Dynamics and Properties of the Cohesive Zone in Rapid Fracture and Friction.

Physical review letters

Berman N, Cohen G, Fineberg J.
PMID: 33016754
Phys Rev Lett. 2020 Sep 18;125(12):125503. doi: 10.1103/PhysRevLett.125.125503.

The cohesive zone is the elusive region in which material fracture takes place. Here, the putatively singular stresses at a crack's tip are regularized. We present experiments, performed on PMMA, in which we visualize the cohesive zone of frictional...

Origin of the microbranching instability in rapid cracks.

Physical review letters

Boué TG, Cohen G, Fineberg J.
PMID: 25699445
Phys Rev Lett. 2015 Feb 06;114(5):054301. doi: 10.1103/PhysRevLett.114.054301. Epub 2015 Feb 02.

The origin of the microbranching instability is a long-standing unresolved issue in the fracture of brittle amorphous materials. We investigate the onset of this instability by measuring the real-time dynamics and symmetries of the strain fields produced by rapid...

Passion matters but not equally everywhere: Predicting achievement from interest, enjoyment, and efficacy in 59 societies.

Proceedings of the National Academy of Sciences of the United States of America

Li X, Han M, Cohen GL, Markus HR.
PMID: 33712544
Proc Natl Acad Sci U S A. 2021 Mar 16;118(11). doi: 10.1073/pnas.2016964118.

How to identify the students and employees most likely to achieve is a challenge in every field. American academic and lay theories alike highlight the importance of passion for strong achievement. Based on a Western independent model of motivation,...

Detachment fronts and the onset of dynamic friction.

Nature

Rubinstein SM, Cohen G, Fineberg J.
PMID: 15329715
Nature. 2004 Aug 26;430(7003):1005-9. doi: 10.1038/nature02830.

The dynamics of friction have been studied for hundreds of years, yet many aspects of these everyday processes are not understood. One such aspect is the onset of frictional motion (slip). First described more than 200 years ago as...

Resumption of sexual activity after acute myocardial infarction and long-term survival.

European journal of preventive cardiology

Cohen G, Nevo D, Hasin T, Benyamini Y, Goldbourt U, Gerber Y.
PMID: 33624045
Eur J Prev Cardiol. 2020 Sep 22; doi: 10.1093/eurjpc/zwaa011. Epub 2020 Sep 22.

AIMS: Sexual activity is an important factor in the overall quality of life. We examined whether resumption of sexual activity frequency within the first few months after myocardial infarction (MI) is associated with long-term survival.METHODS AND RESULTS: Sexually active...

Physical Activity and Long-Term Mortality Risk in Older Adults with and without Cardiovascular Disease: A Nationwide Cohort Study.

Gerontology

Shaked O, Cohen G, Goshen A, Shimony T, Shohat T, Gerber Y.
PMID: 34515134
Gerontology. 2021 Aug 25;1-9. doi: 10.1159/000518169. Epub 2021 Aug 25.

AIMS: To evaluate the association between physical activity (PA) levels and mortality among older adults, to determine whether it differs according to cardiovascular disease (CVD) status, and to assess the optimal weekly duration of PA associated with subsequent survival.METHODS:...

Designing and Evaluating Standard-Setting Procedures for Licensure and Certification Tests.

Advances in health sciences education : theory and practice

Kane MT, Crooks TJ, Cohen AS.
PMID: 12386478
Adv Health Sci Educ Theory Pract. 1999;4(3):195-207. doi: 10.1023/A:1009849528247.

Passing scores for licensure and certification tests are justified by showing that decisions based on the passing score achieve the purposes of the credentialing program while avoiding any serious negative consequences. The standard should be high enough to provide...

Attainable and Relevant Moral Exemplars Are More Effective than Extraordinary Exemplars in Promoting Voluntary Service Engagement.

Frontiers in psychology

Han H, Kim J, Jeong C, Cohen GL.
PMID: 28326045

The present study aimed to develop effective moral educational interventions based on social psychology by using stories of moral exemplars. We tested whether motivation to engage in voluntary service as a form of moral behavior was better promoted by...

The Relationship Between Self-Efficacy and Well-Being Among Surgical Residents.

Journal of surgical education

Milam LA, Cohen GL, Mueller C, Salles A.
PMID: 30245061
J Surg Educ. 2019 Mar - Apr;76(2):321-328. doi: 10.1016/j.jsurg.2018.07.028. Epub 2018 Sep 21.

OBJECTIVE: Residency is a challenging time in the lives of physicians. In this study, we examined the relationship between general self-efficacy, defined as the belief in one's own capabilities in a variety of situations, and burnout and psychological well-being...

A brief social-belonging intervention in college improves adult outcomes for black Americans.
