| 1 | Should,and how can,exercise be done during a coronavirus outbreak? An interview with Dr.Jeffrey A.Woods显示文摘The Coronavirus disease(COVID-19)crisis is now present in China.It started in December,2019 and has,so far,led 213 individuals died and at least 9066 infected in China by local time 17:26,r January 30,2020.It has also spread to a number of Asian countries,as well as to Canada,France,Germany,and the United States.As a result,the Chinese government has put several major cities in Hubei Province on lockdown and has thrown plans for the Lunar New Year holiday into chaos for millions of people.On January 30,2020,the World Health Organization also declared the COVID-19 outbreak a global health emergency because it could spread to countries that are not prepared. | Weimo Zhu | 2020 | Journal of Sport and Health Science2020，9，2： | 11 |
| 2 | Canadian Agility and Movement Skill Assessment(CAMSA):Validity, objectivity, and reliability evidence for children 8–12 years of age显示文摘Purpose: The primary aim of this study was to develop an assessment of the fundamental, combined, and complex movement skills required to support childhood physical literacy. The secondary aim was to establish the feasibility, objectivity, and reliability evidence for the assessment.Methods: An expert advisory group recommended a course format for the assessment that would require children to complete a series of dynamic movement skills. Criterion-referenced skill performance and completion time were the recommended forms of evaluation. Children, 8–12 years of age, self-reported their age and gender and then completed the study assessments while attending local schools or day camps. Face validity was previously established through a Delphi expert(n = 19, 21% female) review process. Convergent validity was evaluated by age and gender associations with assessment performance. Inter-and intra-rater(n = 53, 34% female) objectivity and test–retest(n = 60, 47% female) reliability were assessed through repeated test administration.Results: Median total score was 21 of 28 points(range 5–28). Median completion time was 17 s. Total scores were feasible for all 995 children who self-reported age and gender. Total score did not differ between inside and outside environments(95% confidence interval(CI) of difference:-0.7 to 0.6;p = 0.91) or with/without footwear(95%CI of difference:-2.5 to 1.9; p = 0.77). Older age(p < 0.001, η2= 0.15) and male gender(p < 0.001, η2= 0.02)were associated with a higher total score. Inter-rater objectivity evidence was excellent(intraclass correlation coefficient(ICC) = 0.99) for completion time and substantial for skill score(ICC = 0.69) for 104 attempts by 53 children(34% female). Intra-rater objectivity was moderate(ICC = 0.52) for skill score and excellent for completion time(ICC = 0.99). Reliability was excellent for completion time over a short(2–4 days; ICC = 0.84) or long(8–14days; ICC = 0.82) interval. Skill score reliability was moderate(ICC = 0.46) over a short interval, and substantial(ICC = 0.74) over a long interval.Conclusion: The Canadian Agility and Movement Skill Assessment is a feasible measure of selected fundamental, complex and combined movement skills, which are an important building block for childhood physical literacy. Moderate-to-excellent objectivity was demonstrated for children 8–12 years of age. Test–retest reliability has been established over an interval of at least 1 week. The time and skill scores can be accurately estimated by 1 trained examiner. | Patricia E.Longmuir Charles Boyer Meghann Lloyd Michael M.Borghese Emily Knight Travis J.Saunders Elena Boiarskaia Weimo Zhu Mark S.Tremblay | 2017 | Journal of Sport and Health Science2017，6，2： | 10 |
| 3 | Construction and Characterization of Novel Staphylokinase Variants with Antiplatelet Aggregation Activity and Reduced Immunogenecity显示文摘To develop target thrombolytic agents with fibrinolytic activity, antiplatelet aggregation activity and reduced immunogenicity, two staphylokinase variants containing Arg-Gly-Asp (RGD) motif were constructed. Gene expression was induced in E. coli JF1125 and the variants, designated DGR and RL1, were purified with gel filtration and ion-exchange chromatography and the purity was over 95%. The fibrinolytic activity and kinetic constants of the two variants were comparable to those of recombinant wild-type staphylokinase. Both the variants can inhibit the platelet aggregation at a final concentration of 2 μM. The titers of antibodies against variants were much lower than those against recombinant staphylokinase in guinea pigs, which indicated that the immunogenicity of the variants was greatly reduced. These results confirm that it is possible to design and produce a bifunctional protein that possesses fibrinolytic and antiplatelet aggrega- tion activities. | Hua-BoSU Yu-GaoZHANG Jin-TianHE WeiMO Yan-LingZHANG Xian-MeiTAO Hou-YanSONG | 2004 | Acta Biochimica et Biophysica Sinica2004，36，5： | 7 |
| 4 | Sadly,the earth is still round(p<0.05)显示文摘Looking through any exercise science journals today,in fact any science journals including many top Science Citation Index(SCI) journals,one can easily find examples of the wide-spread 'p<0.05/significance' abuse phenomenon,i.e., if the p value from a statistical/hypothesis test is less than 0.05(or 0.01 sometimes),a conclusion that 'the results/ findings are significant' is then drawn.The abuse is so severe that it is already seriously threatening the integrity of scientific inquiry. | Weimo Zhu | 2012 | Journal of Sport and Health Science2012，1，1： | 7 |

| 7 | Reliability:What type,please!显示文摘Validity and reliability,as we all learned in our first research methods class,are two of the most important qualities of any test,measurement or assessment.When compared with validity, reliability is actually more important since without it, there would be no validity.Since reliability is so important, almost all research journals today have some articles related to reliability.Unfortunately,many of these articles fail to | Weimo Zhu | 2013 | Journal of Sport and Health Science2013，2，1： | 1 |

| 15 | Rational design of robust iridium-ceria oxide-carbon nanofibers to boost oxygen evolution reaction in both alkaline and acidic media显示文摘Anodic oxygen evolution reaction(OER)is essential to participate in diverse renewable energy conversion and storage processes,while most OER electrocatalysts present satisfactory catalytic performance in only alkaline or acidic medium,limiting their practical applications in many aspects.Herein,we have designed and prepared Ir-CeO_(2)-C nanofibers(NFs)via an electrospinning and a relatively low-temperature calcination strategy for OER application in both alkaline and acidic conditions.Density functional theory(DFT)simulations demonstrate the high catalytic active sites of Ir atoms for OER,that the formation of Ir–O bonds at the interface between Ir and CeO_(2)can modulate the electron density of the relevant Ir atoms to promote the OER activity.In addition,the unique nanofibrous heterostructure increases the exposed active sites and promotes the electrical conductivity.Therefore,the prepared Ir-CeO_(2)-C nanofibrous catalyst delivers an excellent OER property in both alkaline and acidic solutions.Impressively,the overpotentials to reach 10 mA·cm^(−2)are only 279 and 283 mV in the alkaline and acidic electrolyte,respectively,with favorable long-term stabilities.In addition,the two-electrode overall water splitting set-ups equipped with Ir-CeO_(2)-C NFs as anode and commercial Pt/C as cathode provide a cell voltage of 1.54 and 1.53 V to drive 10 mA·cm^(−2)in the alkaline and acidic electrolyte,respectively,which are much lower than Pt/C||IrO_(2)and lots of transition metal oxides-based electrolyzers.This research presents an efficient means to design OER catalysts with superior properties in both alkaline and acidic solutions. | Xiaojie Chen Wenying Liao Mengxiao Zhong Junjie Chen Su Yan Weimo Li Ce Wang Wei Chen Xiaofeng Lu | 2023 | Nano Research2023，16，5： | 1 |

| 19 | '17% at or above the 95th percentile'——What is wrong with this statement?显示文摘When reporting the prevalence of childhood obesity in the USA a few years ago,the magazine U.S.News & World Report stated: '...some 17 percent of kids are now obese,which means they’re at or above the 95th percentile for weight in relation to height for their age;an additional 17 percent are overweight, or at or over the 85th percentile.' Anyone with some basic training in measurement or statistics will realize that this statement is incorrect.This is because the percentile is defined as the value below which a certain percent of observations fall in a population.For example,the | Weimo Zhu | 2012 | Journal of Sport and Health Science2012，1，2： | 0 |
| 20 | Transfer characteristics of dynamic biochemical signals in non-reversing pulsatile flows in a shallow Y-shaped microfluidic channel: signal filtering and nonlinear amplitude-frequency modulation显示文摘The transports of the dynamic biochemical signals in the non-reversing pulsatile flows in the mixing microchannel of a Y-shaped microfluidic device are analyzed. The results show that the mixing micro-channel acts as a low-pass filter, and the biochemical signals are nonlinearly modulated by the pulsatile flows, which depend on the biochemical signal frequency, the flow signal frequency, and the biochemical signal transporting distance. It is concluded that, the transfer characteristics of the dynamic biochemical signals, which are transported in the time-varying flows, should be carefully considered for better loading biochemical signals on the cells cultured on the bottom of the microfluidic channel. | Zongzheng CHEN Weimo YUAN A.R.AZIZ Zhengming GAO Depei ZENG Bo LIU Kairong QIN | 2017 | Applied Mathematics and Mechanics(English Edition)2017，38，10： | 0 |
