| 1 | 基于强化学习的自主式水下潜器障碍规避技术(英文)显示文摘Obstacle avoidance becomes a very challenging task for an autonomous underwater vehicle(AUV)in an unknown underwater environment during exploration process.Successful control in such case may be achieved using the model-based classical control techniques like PID and MPC but it required an accurate mathematical model of AUV and may fail due to parametric uncertainties,disturbance,or plant model mismatch.On the other hand,model-free reinforcement learning(RL)algorithm can be designed using actual behavior of AUV plant in an unknown environment and the learned control may not get affected by model uncertainties like a classical control approach.Unlike model-based control model-free RL based controller does not require to manually tune controller with the changing environment.A standard RL based one-step Q-learning based control can be utilized for obstacle avoidance but it has tendency to explore all possible actions at given state which may increase number of collision.Hence a modified Q-learning based control approach is proposed to deal with these problems in unknown environment.Furthermore,function approximation is utilized using neural network(NN)to overcome the continuous states and large statespace problems which arise in RL-based controller design.The proposed modified Q-learning algorithm is validated using MATLAB simulations by comparing it with standard Q-learning algorithm for single obstacle avoidance.Also,the same algorithm is utilized to deal with multiple obstacle avoidance problems. | Prashant Bhopale Faruk Kazi Navdeep Singh | 2019 | Journal of Marine Science and Application2019，18，2： | 5 |

| 18 | Evaluation of corrosion resistance, mechanical integrity loss and biocompatibility of PCL/HA/TiO_(2) hybrid coated biodegradable ZM21 Mg alloy显示文摘A novel PCL/HA/TiO_(2)hybrid coating on ZM21 Mg alloy substrate has been investigated for corrosion resistance, biocompatibility and mechanical integrity loss in terms of bending, compressive and tensile strength in physiological media. The prepared hybrid coating was dip coated over ZM21 from HA/TiO_(2)and PCL solutions followed by creating a microporous PCL layer by utilizing Non-solvent Induced Phase Separation(NIPS) technique. The electrochemical measurement and in-vitro degradation study in SBF after 28 days showed that the PCL/HA/TiO_(2) hybrid coating reduced H2 evolution rate, weight loss, and corrosion rate by 64, 116 and 118 times respectively, as compared to uncoated ZM21 samples. The surface studies carried out using SEM-EDX, FTIR and XRD revealed formation of highly stable 3d flower-like HA crystals with Ca/P ratio of 1.60 in the PCL micropores. This dense apatite growth effectively protected the PCL/HA/TiO_(2)hybrid coated samples to maintain the good mechanical integrity even after 28 days of immersion as compared to HA/TiO_(2)composite coated, As-polished(A/P) and As-machined(A/M) samples. The failure analysis of samples under mechanical loading were performed using SEM-BSE-EBSD.The in-vitro cellular viability of L929 fibroblast cells on PCL/HA/TiO_(2)hybrid coating was found 50.47% higher with respect to control group,whereas bacterial viability was supressed by 57.15 and 62.35% against gram-positive Staphylococcus aureus and gram-negative Escherichia coli bacterial models. The comprehensive assessment indicates PCL/HA/TiO_(2)hybrid coating as a suitable candidate to delay early degradation and mechanical integrity loss of Mg-based alloys for devising biodegradable orthopaedic implant. | Navdeep Singh Uma Batra Kamal Kumar Anil Mahapatro | 2022 | Journal of Magnesium and Alloys2022，10，11： | 0 |
| 19 | Psychotic symptoms in bipolar disorder and their impact on the illness:A systematic review显示文摘BACKGROUND Lifetime psychotic symptoms are present in over half of the patients with bipolar disorder(BD)and can have an adverse effect on its course,outcome,and treatment.However,despite a considerable amount of research,the impact of psychotic symptoms on BD remains unclear,and there are very few systematic reviews on the subject.AIM To examine the extent of psychotic symptoms in BD and their impact on several aspects of the illness.METHODS The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed.An electronic literature search of six English-language databases and a manual search was undertaken to identify published articles on psychotic symptoms in BD from January 1940 to December 2021.Combinations of the relevant Medical Subject Headings terms were used to search for these studies.Articles were selected after a screening phase,followed by a review of the full texts of the articles.Assessment of the methodological quality of the studies and the risk of bias was conducted using standard tools.RESULTS This systematic review included 339 studies of patients with BD.Lifetime psychosis was found in more than a half to two-thirds of the patients,while current psychosis was found in a little less than half of them.Delusions were more common than hallucinations in all phases of BD.About a third of the patients reported first-rank symptoms or mood-incongruent psychotic symptoms,particularly during manic episodes.Psychotic symptoms were more frequent in bipolar type I compared to bipolar type II disorder and in mania or mixed episodes compared to bipolar depression.Although psychotic symptoms were not more severe in BD,the severity of the illness in psychotic BD was consistently greater.Psychosis was usually associated with poor insight and a higher frequency of agitation,anxiety,and hostility but not with psychiatric comorbidity.Psychosis was consistently linked with increased rates and the duration of hospitalizations,switching among patients with depression,and poorer outcomes with mood-incongruent symptoms.In contrast,psychosis was less likely to be accompanied by a rapid-cycling course,longer illness duration,and heightened suicidal risk.There was no significant impact of psychosis on the other parameters of course and outcome.CONCLUSION Though psychotic symptoms are very common in BD,they are not always associated with an adverse impact on BD and its course and outcome. | Subho Chakrabarti Navdeep Singh | 2022 | World Journal of Psychiatry2022，12，9： | 0 |
| 20 | Novel PA encapsulated PCL hybrid coating for corrosion inhibition of biodegradable Mg alloys:A triple triggered self-healing response for synergistic multiple protection显示文摘Surface coatings have been extensively used to control the degradation rate of Mg alloys for bioimplant applications.However,these coatings only act as passive barriers.In corrosive media,structural damage impairs their barrier properties,resulting in rapid degradation of Mg alloys.The present study incorporates phytic acid(PA)as a healing agent in polycaprolactone(PCL)microcapsules with a unique honeycomb core matrix to obtain a self-healing PA-PCLcaps coating.The contact between simulated body fluid(SBF)and PA-PCLcaps coated ZM21 exhibited Cassie-Baxter interfacial states,resulting in significant hydrophobicity with a contact angle(CA)of 116.3.The corrosion potential(Ecorr)and current density(Icorr)were found to be-0.28 V and 1.1×10^(-9)A/cm^(2),respectively,for PA-PCLcaps coating,resulting in biosafe corrosion rate of 2.5×10^(-4)mm/year.After mechanical scratching,rapid HA mineralization at scratched regions recovered the hydrogen evolution rate(HER,0.36 mL/cm^(2)/day)and pH change(pH 7.10)of scratched PA-PCLcaps coated ZM21 samples to corresponding unscratched samples within one day of immersion.The coating’s self-healing ability could be attributed to PA released from punctured microcapsules,which facilitates HA chelation.The pH-triggered(pH 10)and Mg(II)-triggered(5 mM)conditions enhanced PA release from PA-PCLcaps coating by 2.5 and 3.1 times,respectively.As a result,dense HA mineralization occurred,which protects the coating from structural defects and ensures its durability in stimulating conditions.The findings of present study provide new insight for design of multiple stimuli-feedback based self-healing coatings on biodegradable Mg alloys. | Navdeep Singh Grewal Uma Batra Kamal Kumar Anil Mahapatro | 2023 | Journal of Magnesium and Alloys2023，11，4： | 0 |
