1Enhanced recovery after surgery programs in patients undergoing hepatectomy:A meta-analysis显示文摘AIM:To evaluate the impact of enhanced recovery after surgery(ERAS) programs in comparison with traditional care on liver surgery outcomes.METHODS:The Pub Med,EMBASE,CNKI and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials(RCTs) comparing the ERAS program with traditional care in patients undergoing liver surgery. Studies selected for the meta-analysis met all of the following inclusion criteria:(1) evaluation of ERAS in comparison to traditional care in adult patients undergoing elective open or laparoscopic liver surgery;(2) outcome measures including complications,recovery of bowel function,and hospital length of stay; and(3) RCTs. The following exclusion criteria were applied:(1) the study was not an RCT;(2) the study did not compare ERAS with traditional care;(3) the study reported on emergency,non-elective or transplantation surgery; and(4) the study consisted of unpublished studies with only the abstract presented at a national or international meeting. The primary outcomes were complications. Secondary outcomes were length of hospital stay and time to first flatus.RESULTS:Five RCTs containing 723 patients were included in the meta-analysis. In 10/723 cases,patients presented with benign diseases,while the remaining 713 cases had liver cancer. Of the five studies,three were published in English and two were published in Chinese. Three hundred and fifty-four patients were in the ERAS group,while 369 patients were in the traditional care group. Compared with traditional care,ERAS programs were associated with significantly decreased overall complications(RR = 0.66; 95%CI:0.49-0.88; P = 0.005),grade?Ⅰ?complications(RR = 0.51; 95%CI:0.33-0.79; P = 0.003),and hospitallength of stay [WMD =-2.77 d,95%CI:-3.87-(-1.66); P < 0.00001]. Similarly,ERAS programs were associated with decreased time to first flatus [WMD =-19.69 h,95%CI:-34.63-(-4.74); P < 0.0001]. There was no statistically significant difference in grade Ⅱ-Ⅴ complications between the two groups.CONCLUSION:ERAS is a safe and effective program in liver surgery. Future studies should define the active elements to optimize postoperative outcomes for liver surgery.Tian-Gen Ni Han-Teng Yang Hao Zhang Hai-Peng Meng Bo Li 2015World Journal of Gastroenterology2015,21,30:34
2Diagnosis and treatment of spontaneous colonic perforation:Analysis of 10 cases显示文摘AIM: To investigate the etiology, diagnosis and treatment of spontaneous perforation of the colon. METHODS: The clinical data of 10 cases of spontaneous perforation of the colon, observed at Fuding hospital from January 2004 to December 2007, were analyzed retrospectively. RESULTS: The mean age at onset was 65 years (range from 45 to 73). Seven patients had a history of chronic constipation. All patients complained of sudden lower abdominal pain. The perforation occurred after coloclysis and administration of senna leaves in two patients. Nine patients had signs of peritoneal irritation. Seven cases underwent abdominal paracentesis, which was diagnostic in six. Only one case was definitely diagnosed prior to surgery. One patient underwent neoplasty of the colon, another a partial resection of colon, six a neoplasty of the colon plus sigmoid colostomy, and two underwent Hartmann surgery. All perforation sites were opposite to the mesenteric edge. The perforation sites were located on descending colon in one case, sigmoid colon in three cases, and rectosigmoid colon in six cases. In five patients, surgical pathological examination was consistent with the microscopical changes of colonic perforation caused by feces. Three patients died after surgery. CONCLUSION: Spontaneous perforation of the colon most commonly occurs among the elderly with chronic constipation. Abdominal paracentesis is helpful for the diagnosis. The perforation site is located opposite to the mesenteric edge. Sigmoid colon and rectosigmoid colon are the most frequent locations. Neoplasty of the colon and sigmoid colostomy are the most frequenttreatment. The prognosis is bad and the mortality rate after surgery is high.Bo Yang Huai-Kun Ni 2008World Journal of Gastroenterology2008,14,28:24

4Future 5G-Oriented System for Urban Rail Transit:Opportunities and Challenges显示文摘As a development direction of urban rail transit system,the train autonomous circumambulate system(TACS)can operate in a safer,more efficient,and more economical mode.However,most urban rail transit systems transmit signals through industrial,scientific,and medical(ISM)frequency bands or narrow frequency bands,which cannot meet the requirements of TACS.As a promising solution,the 5th generation(5G)mobile communication provides more services for the future urban rail transit systems,and covers the shortages of exiting communication technologies in terms of capacity and reliability.In this paper,we first briefly review the research status of current train control system and introduce its limitations.Next,we propose a novel network architecture,and present new technologies and requirements of the proposed architecture for TACS.Some potential challenges are then discussed to give insights for further research of TACS.Junhui Zhao Jin Liu Lihua Yang Bo Ai Shanjin Ni 2021China Communications2021,18,2:18
5Using shapes correlation for active contour segmentation of uterine fibroid ultrasound images in computer-aided therapy显示文摘Segmenting the lesion regions from the ultrasound(US) images is an important step in the intra-operative planning of some computer-aided therapies. High-Intensity Focused Ultrasound(HIFU), as a popular computer-aided therapy, has been widely used in the treatment of uterine fibroids. However, such segmentation in HIFU remains challenge for two reasons:(1)the blurry or missing boundaries of lesion regions in the HIFU images and(2) the deformation of uterine fibroids caused by the patient's breathing or an external force during the US imaging process, which can lead to complex shapes of lesion regions. These factors have prevented classical active contour-based segmentation methods from yielding desired results for uterine fibroids in US images. In this paper, a novel active contour-based segmentation method is proposed, which utilizes the correlation information of target shapes among a sequence of images as prior knowledge to aid the existing active contour method. This prior knowledge can be interpreted as a unsupervised clustering of shapes prior modeling. Meanwhile, it is also proved that the shapes correlation has the low-rank property in a linear space, and the theory of matrix recovery is used as an effective tool to impose the proposed prior on an existing active contour model. Finally, an accurate method is developed to solve the proposed model by using the Augmented Lagrange Multiplier(ALM). Experimental results from both synthetic and clinical uterine fibroids US image sequences demonstrate that the proposed method can consistently improve the performance of active contour models and increase the robustness against missing or misleading boundaries, and can greatly improve the efficiency of HIFU therapy.NI Bo HE Fa-zhi PAN Yi-teng YUAN Zhi-yong 2016Applied Mathematics(A Journal of Chinese Universities)2016,31,1:14
6Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD.Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao 2018Bone Research2018,6,3:13

8GABAergic Abnormalities Associated with Sensorimotor Corticostriatal Community Structural Deficits in ErbB4 Knockout Mice and First-Episode Treatment-Naive Patients with Schizophrenia显示文摘The current study was designed to explore how disruption of specific molecular circuits in the cerebral cortex may cause sensorimotor cortico-striatal community structure deficits in both a mouse model and patients with schizophrenia.We used prepulse inhibition(PPI)and brain structural and diffusion MRI scans in 23 mice with conditional ErbB4 knockout in parvalbumin interneurons and 27 matched controls.Quantitative real-time PCR was used to assess the differential levels of GABA-related transcripts in brain regions.Concurrently,we measured structural and diffusion MRI and the cumulative contribution of risk alleles in the GABA pathway genes in firstepisode treatment-naı¨ve schizophrenic patients(n=117)and in age-and sex-matched healthy controls(n=86).We present the first evidence of gray and white matter impairment of right sensorimotor cortico-striatal networks and reproduced the sensorimotor gating deficit in a mouse model of schizophrenia.Significant correlations between gray matter volumes(GMVs)in the somatosensory cortex and PPI as well as glutamate decarboxylase 1 mRNA expression were found in controls but not in knockout mice.Furthermore,these findings were confirmed in a human sample in which we found significantly decreased gray and white matter in sensorimotor cortico-striatal networks in schizophrenic patients.The psychiatric risk alleles of the GABA pathway also displayed a significant negative correlation with the GMVs of the somatosensory cortex in patients.Our study identified that ErbB4 ablation in parvalbumin interneurons induced GABAergic dysregulation,providing valuable mechanistic insights into the sensorimotor cortico-striatal community structure deficits associated with schizophrenia.Chengcheng Zhang Peiyan Ni Yikang Liu Yang Tian Jinxue Wei Bo Xiang Liansheng Zhao Xiaojing Li Xiaohong Ma Wei Deng Wanjun Guo Rongjun Ni Yamin Zhang Qiang Wang Hailiang Huang Nanyin Zhang Tao Li 2020Neuroscience Bulletin2020,36,2:9
9Anti-scourability of purple soil on hillslopes with different land uses显示文摘A large-scale flume (40 cm×10 cm×10 cm) was used to determine soil anti-scourability of 4 different land uses of purple soil in hilly areas of Sichuan, China under artificial removal of vegetation to examine the effects of land uses on sediment production by runoff. The results showed that soil anti-scourability declined with the increase of slope gradients in the form of power function, but there was a significant difference in the effects of slope gradients on anti-scourability between different land uses. The ratio of the mean values of soil anti-scourability was 1︰2.2︰2.5︰3.6 for forest land, new waste pasture, old waste pasture, crop land respectively, indicating that forest and grass use can significantly improve soil anti-scourability. Compared with the observations from the runoff plots located at the same sites in this region, an inconsistent result was found between anti-scourability and anti-erodibility in hilly areas of Sichuan. Essential causes of the differences in soil anti-scourability were further discussed based on analyzing the influence of inherent soil characteristics induced by different land uses on soil anti-scourability.ZHANG Jianhui, LIU Gangcai, NI Shijun, ZHU Bo & GE Fanglong Institute of Mountain Hazards and Environment, Chinese Academy of Sciences and Ministry of Water Resources, Chengdu 610041, China Chengdu University of Technology, Chengdu 610059, China 2003Science China(Technological Sciences)2003,46,z1:8
10Impacts of algal blooms removal by chitosan-modified soils on zooplankton community in Taihu Lake,China显示文摘It is important to assess the eflect on zooplankton when perform the environmental protection or restoration technology,especially removing algal blooms,because algae were the major primary producer in algal lakes.The influence on zooplankton community after half a year of algal blooms removed by chitosan-modified soils in Taihu Lake was assessed and the rationality of carrying out the process semiannually was evaluated in the present study.Morphological composition and genetic diversity of zooplankton community were investigated by microscope checkup and polymerase chain reaction-denatured gradient gel electrophoresis(PCR-DGGE) .A total of 44 zooplankton taxa(23 protozoa,17 rotifers,3 copepoda and 1 cladocera) were detected by microscope checkup,and a total of 91 bands(28 bands amplified by primers F1427-GC and R1616,63 bands amplified by primers Fung-GC and NS1) were detected by PCR-DGGE.The results of cluster analysis or detrended correspondence analysis indicated that there was no considerable diflerence in morphological composition of zooplankton and DGGE profiles between experimental and control sites,and DGGE profiles could represent the biologic diversity.The study showed that zooplankton community could recover original condition after half year of algal blooms removed by chitosan-modified soils and it was acceptable to apply this process semiannually.In addition,the results revealed that PCR-DGGE could be applied to investigate the impacts of the environmental protection or restoration engineering on zooplankton community diversity.Jiajia Ni Yuhe Yu Weisong Feng Qingyun Yan Gang Pan Bo Yang Xiang Zhang Xuemei Li 2010Journal of Environmental Sciences2010,22,10:8
11^(18)F-fluorodeoxyglucose PET/CT findings of a solitary primary hepatic lymphoma:A case report显示文摘Primary hepatic lymphoma is extremely rare,and only a few cases have been described on positron emission tomography(PET) or PET/computed tomography(PET/CT) imaging in the English literature.We report a case of a 55-year-old woman who presented with low-grade fever and weight loss of three months.On CT scanning,a mass was identified which appeared to be a hypoattenuating lesion,on ultrasonographic imaging,the mass was hypoechoic,therefore,liver abscess or hepatic metastasis from a gastrointestinal primary was initially suspected.Tumor markers such as alpha-fetoprotein,carcinoembryonic antigen and carbohydrate antigen 19-9 were within normal limits.PET/CT demonstrated a large abnormal ring-like hypermetabolic focus in the right liver lobe.The lesion was resected and the histo-pathological findings were consistent with lymphoma.The patient was discharged two weeks after surgery and did not receive any further treatment.After 25 mo follow-up,she is in good health.18F-fluorodeoxyglucose PET/CT is useful in confirming the diagnosis of primary hepatic lymphoma by demonstrating no other foci with high uptake in other parts of the body.Bo Pan Cun-Shi Wang Jian-Kui Han Lin-Feng Zhan Ming Ni Shi-Cheng Xu 2012World Journal of Gastroenterology2012,18,48:6
12Integrated Forest Biorefinery:Value-added Utilization of Dissolved Organics in the Prehydrolysis Liquor of Prehydrolysis Kraft (PHK) Dissolving Pulp Production Process显示文摘The concept of integrated forest biorefineries(IFBRs) has gained significant interest.The prehydrolysis kraft(PHK) dissolving pulp production process is a suitable example of IFBR concept for the production of dissolving pulp and utilization of dissolved hemicelluloses,acetic acid,and lignin in the prehydrolysis liquor(PHL).This review paper highlights recent progress related to the recovery and utilization of dissolved organics(e.g.,hemicelluloses,acetic acid,and lignin) in the PHL of the PHK dissolving pulp production process.Integrated multi-step recovery and separation processes have been developed for this purpose to accommodate the complex nature of the PHL.Potential products,including xylan-based compounds,acetic acid,and lignin,are also discussed in detail.Bo Yang BaoBin Wang GuanHua Wang ZhiBin He YongHao Ni 2018Paper And Biomaterials2018,3,3:6
13Experimental investigation of laser-produced-plasma EUV source based on liquid target显示文摘A laser-produced plasma(LPP) source was built using liquid as target and a Nd:YAG laser as the irradiation laser, and the LPP source's radiation with ethanol and acetone target respectively was measured by an AXUV100 silicon photodiode combined with a McPHERSON model 247 grazing incidence monochromator of the resolution Δλ≤0.075 nm and the wavelength scanning interval 0.5 nm. Both ethanol and acetone target LPP source had EUV emission at 11~20 nm wavelength. The comparison between the spectra of the two kinds of target materials shows that all the two kinds of target source's spectra are the result of oxygen ions' transitions under current source's parameters, but the spectrum intensity from different target sources is different. The spectra intensity from the ethanol target is higher than that from the acetone target. In addition, the target liquid is forced into the vacuum chamber by the background pressure supported by the connected external high pressure gas, and the influence of the background pressure on the source's intensity is investigated.QI Li-hong NI Qi-liang CHEN Bo 2005光学精密工程2005,13,5:6
14Integration of a Nonlinear Vibration Absorber and Levitation Magnetoelectric Energy Harvester for Whole-Spacecraft Systems显示文摘This paper presents a new device integrating a nonlinear vibration absorber with a levitation magnetoelectric energy harvester for whole-spacecraft systems. This device effectively reduces vibration and has a stronger energy harvesting capability than the existing systems. It harvests energy from a wide frequency range and has a high output voltage. The harvested energy is determined by magnetic field strength, excitation frequency, and resistive load. The change in the magnetic field strength has the least impact on the output voltage. The vibration reduction effects and harvested energy of the system are analyzed with an approximate analytical method that combines the harmonic balance approach and the pseudo-arclength continuation algorithm. The results of the Runge-Kutta method are nearly consistent with those of the approximate analytical method. Moreover, the effects of the excitation frequency, resistive load, and parameters of the nonlinear energy sink on the system vibration response and energy harvesting are analyzed.Ye-Wei Zhang Zhi-Wei Fang Shi-Lei Wang Zhi-Yu Ni Jian Zang Bo Fang 2019Acta Mechanica Solida Sinica2019,32,3:6
15An Improved vTPM-VM Live Migration Protocol显示文摘To prevent malicious virtual machine from harming the security of vTPM-VM live migration process, we propose an improved vTPM-VM live migration protocol which uses a TPM-based integrity verification policy and a specific encryption scheme to enhance security. The TPM-based integrity verification policy is presented to ensure that all participating entities in this process are trustworthy. In data transfer phase, the specific encryption scheme is designed to associate the decipher process with one certain platform status so that only the destination platform can gain the key data of the migrated VM and vTPM instance. The security of this new protocol is analyzed. The results show that this protocol can effectively resist most of the attacks in the process of vTPM-VM live migration.FAN Peiru ZHAO Bo SHI Yuan CHEN Zhihong NI Mingtao 2015Wuhan University Journal of Natural Sciences2015,20,6:5
16Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting.Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu 2021Cancer Communications2021,41,9:5

18Zinc finger E-box-binding homeobox 1 mediates aerobic glycolysis via suppression of sirtuin 3 in pancreatic cancer显示文摘AIM To uncover the roles of tumor-promoting gene ZEB1 in aerobic glycolysis regulation and shed light on the underlying molecular mechanism.METHODS Endogenous zinc finger E-box binding homeobox-1(ZEB1) was silenced using a lentivirus-mediated method, and the impact of ZEB1 and methyl-CpG binding domain protein 1(MBD1) on aerobic glycolysis was measured using seahorse cellular flux analyzers, reactive oxygen species quantification, and mitochondrial membrane potential measurement. The interaction between ZEB1 and MBD1 was assessed by co-immunoprecipitation and immunofluorescence assays. The impact of ZEB1 and MBD1 interaction on sirtuin 3(SIRT3) expression was confirmed by quantitative polymerase chain reaction, western blotting, and dual-luciferase and chromatinimmunoprecipitation assays.RESULTS ZEB1 was a positive regulator of aerobic glycolysis in pancreatic cancer. ZEB1 transcriptionally silenced expression of SIRT3, a mitochondrial-localized tumor suppressor, through interaction with MBD1. CONCLUSION ZEB1 silenced SIRT3 expression via interaction with MBD1 to promote aerobic glycolysis in pancreatic cancer.Wen-Yan Xu Qiang-Sheng Hu Yi Qin Bo Zhang Wen-Sheng Liu Quan-Xing Ni Jin Xu Xian-Jun Yu 2018World Journal of Gastroenterology2018,24,43:4
19Abnormal characterization of dynamic functional connectivity in Alzheimer’s disease显示文摘Numerous studies have shown abnormal brain functional connectivity in individuals with Alzheimer’s disease(AD)or amnestic mild cognitive impairment(aMCI).However,most studies examined traditional resting state functional connections,ignoring the instantaneous connection mode of the whole brain.In this case-control study,we used a new method called dynamic functional connectivity(DFC)to look for abnormalities in patients with AD and aMCI.We calculated dynamic functional connectivity strength from functional magnetic resonance imaging data for each participant,and then used a support vector machine to classify AD patients and normal controls.Finally,we highlighted brain regions and brain networks that made the largest contributions to the classification.We found differences in dynamic function connectivity strength in the left precuneus,default mode network,and dorsal attention network among normal controls,aMCI patients,and AD patients.These abnormalities are potential imaging markers for the early diagnosis of AD.Cui Zhao Wei-Jie Huang Feng Feng Bo Zhou Hong-Xiang Yao Yan-E Guo Pan Wang Lu-Ning Wang Ni Shu Xi Zhang 2022Neural Regeneration Research2022,17,9:4
20Powermitter:Data Exfiltration from Air-Gapped Computer through Switching Power Supply显示文摘Air-gapped computers are isolated both logically and physically from all kinds of existing common communication channel, such as USB ports, wireless and wired networks. Although the feasibility of infiltrating an air-gapped computer has been proved in recent years, data exfiltration from such systems is still considered to be a challenging task. In this paper we present Powermitter, a novel approach that can exfiltrate data through an air-gapped computer via its power adapter. Our method utilizes the switched-mode power supply, which exists in all of the laptops, desktop computers and servers nowadays. We demonstrate that a malware can indirectly control the electromagnetic emission frequency of the power supply by leveraging the CPU utilization. Furthermore, we show that the emitted signals can be received and demodulated by a dedicated device. We present the proof of concept design of the power covert channel and implement a prototype of Powermitter consisting of a transmitter and a receiver. The transmitter leaks out data by using a variant binary frequency shift keying modulation, and the emitted signal can be captured and decoded by software based virtual oscilloscope through such covert channel. We tested Powermitter on three different computers. The experiment re-sults show the feasibility of this power covert channel. We show that our method can also be used to leak data from different types of embedded systems which use switching power supply.Bo Zhao Mingtao Ni Peiru Fan 2018China Communications2018,15,2:4
