Reversal of Nonlocal Vortex Motion in the Regime of Strong Nonequilibrium

We investigate nonlocal vortex motion in weakly pinning a-NbGe nanostructures, which is driven by a transport current I and remotely detected as a nonlocal voltage Vnl. At high I, the measured Vnl exhibits dramatic sign reversals that at low and high temperatures T occur for opposite polarities of I. The sign of Vnl becomes independent of that of the drive current at large abs(I). These unusual effects can be nearly quantitatively explained by a novel enhancement of magnetization, arising from a nonequilibrium distribution of quasiparticles at high T, and a Nernst-like effect resulting from local electron heating at low T

Linkage disequlibrium in populations of Merodon avidus A. (Diptera, Syrphidae)

Analysis of the genetic structure in the populations of Merodon avidus A originated from the Dubašnica Mountain, Serbia (AADUB), Pindos Mountain Greece (AAPIN) and Morinj, Montenegro (AAMOR) was done. Based on the polyacrylamide gel electrophoresis out of 16 analyzed loci 10 izozymic loci were monomorphic: Aat, Fum, Hk-2, Hk-3, Idh-2, Mdh-1, Pgm, Sod-1, Sod-2 Sod-3. Nonrandom association between alleles of the Ao and Me in the AAMOR population has been registered. Significant association among alleles of the Ao and Mdh-2 loci in AADUB and Ao and Gpd-2 loci in AAPIN was found as well. Percent of the locus with observed significant gametic disequilibrium was from 16.7% in AAMOR to significant association of the only variable loci pair in AADUB and AAPIN

Nonlocal vs local vortex dynamics in the transversal flux transformer effect

In this follow-up to our recent Letter [F. Otto et al., Phys. Rev. Lett. 104, 027005 (2010)], we present a more detailed account of the superconducting transversal flux transformer effect (TFTE) in amorphous (a-)NbGe nanostructures in the regime of strong nonequilibrium in local vortex motion. Emphasis is put on the relation between the TFTE and local vortex dynamics, as the former turns out to be a reliable tool for determining the microscopic mechanisms behind the latter. By this method, a progression from electron heating at low temperatures T to the Larkin-Ovchinnikov effect close to the transition temperature Tc is traced over a range 0.26 < T/Tc < 0.95. This is represented by a number of relevant parameters such as the vortex transport entropy related to the Nernst-like effect at low T, and a nonequilibrium magnetization enhancement close to Tc. At intermediate T, the Larkin-Ovchinnikov effect is at high currents modified by electron heating, which is clearly observed only in the TFTE

Perspectives on Women’s Higher Education Leadership from around the World

At this time in world history, numerous scholars have emphasized the importance of having greater diversity in leadership, and specifically having greater representation by women in leadership. In particular, providing women with greater access to higher education—and having role models for women in higher education leadership—has a beneficial ripple effect, given that postsecondary institutions shape the lives of future generations. Individuals, nations, and the world collectively pay a price when women are not given full opportunities to develop and contribute their talents by serving on senior-level leadership teams. This Special Issue, titled “Perspectives on Women’s Higher Education Leadership From Around the World,” offers an array of articles that present research findings from both qualitative and quantitative studies, along with narratives and best practices gleaned from the lived experiences of women in academic leadership from countries on four continents: the United States, the United Kingdom, Australia, India, China, and Saudi Arabia. Taken together, these articles offer a helpful overview of the literature related to women in higher education leadership worldwide, thus addressing previous concerns that much of the research has too often taken a Western perspective that reflects inaccurate assumptions for other cultural contexts

UTJECAJ DUŽINE TRANSPORTA I MIJEŠANJA GRUPA NA KAKVOĆU JUNEĆIH TRUPOVA SIMENTALSKIH BIKOVA

In the last few years, beef producers have had great problems with beef distribution, related primarily to the frequent incidence of dark, firm, dry meat. Consumers are unlikely to buy and consume such meat. The aim of this study was to examine the effect of transport period and mixing of groups during rest period in lairage on the quality of beef carcasses. The study included 40 Simmental bulls aged from 18 to 20 months. Ultimate pH value and meat colour were measured 24 hours post mortem in m. longissimus dorsi and m. gracilis. Only 45% of carcasses were within the standard pHu range. Results of transport period did not show significant effect on beef quality. In contrast to transport period, mixing of groups during rest period in lairage had highly significant adverse effect on beef quality (p<0.001). The effect of mixing of bulls during the resting period of 18 hours, could however be regarded of being the main stress factor.Proizvođači junećega mesa proteklih godina imaju značajne probleme u plasmanu junetine, prvenstveno zbog učestalije pojave tamnog suhog i tvrdog mesa (DFD).

Critical behavior of the long-range Ising chain from the largest-cluster probability distribution

Monte Carlo simulations of the 1D Ising model with ferromagnetic interactions decaying with distance $r$ as $1/r^{1+\sigma}$ are performed by applying the Swendsen-Wang cluster algorithm with cumulative probabilities. The critical behavior in the non-classical critical regime corresponding to $0.5 <\sigma < 1$ is derived from the finite-size scaling analysis of the largest cluster.Comment: 4 pages, 2 figures, in RevTeX, to appear in Phys.

Efficacy of combined oral contraceptives for depressive symptoms and overall symptomatology in premenstrual syndrome:pairwise and network meta-analysis of randomized trials

OBJECTIVE: Combined oral contraceptives are often considered a treatment option for women with premenstrual syndrome (PMS) or premenstrual dysphoric disorder (PMDD) also seeking contraception, but evidence for this treatment is scarce. We aimed to determine 1) the level of evidence for the efficacy of combined oral contraceptives in managing premenstrual depressive symptoms and overall premenstrual symptomatology, and 2) the comparative efficacy of combined oral contraceptives (PROSPERO registration number CRD42020205510). DATA SOURCES: We searched Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Web of Science, PsycINFO, Emcare, and EMBASE from inception to June 3rd, 2021. STUDY ELIGIBILITY: All randomized clinical trials that evaluated efficacy of combined oral contraceptives in women with PMS or PMDD were considered eligible for inclusion in the present meta-analysis. STUDY APPRAISAL AND SYNTHESIS METHODS: A random effect Bayesian pairwise and network meta-analysis was conducted with change in premenstrual depressive symptoms and overall premenstrual symptomatology between baseline and 3 cycles as outcome. Certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Of 3664 records, nine eligible trials were included that studied 1205 women with PMS or PMDD (mean age per study range: 24.6-36.5 years). The pairwise meta-analysis revealed that combined oral contraceptives were more efficacious than placebo in treating overall premenstrual symptomatology (standardized mean difference SMD [95%CrI], 0.41 [0.17, 0.67]), but not premenstrual depressive symptoms specifically (SMD [95%CrI], 0.22 [-0.06, 0.47]). However, none of the combined oral contraceptives were more effective than each other in reducing premenstrual depressive symptoms and overall premenstrual symptomatology. CONCLUSIONS: Combined oral contraceptives may improve overall premenstrual symptomatology in women with PMS or PMDD, but not premenstrual depressive symptoms. There is no evidence for one combined oral contraceptive being more efficacious than any other

Anisotropic flow of charged particles at sNN=2.76\mathbf{\sqrt{s_{NN}} = 2.76} TeV measured with the ALICE detector

Measurements of anisotropic flow in heavy-ion collisions provide evidence for the creation of strongly interacting matter which appears to behave as an almost ideal fluid. Anisotropic flow signals the presence of multiple interactions and is very sensitive to the initial spatial anisotropy of the overlap region in non-central heavy-ion collisions. In this article we report measurements of elliptic $v_2$, triangular $v_3$, quadrangular $v_4$ and pentagonal $v_5$ flow. These measurements have been performed with 2- and multi-particle correlation techniques.Comment: 4 pages, 4 figures, Quark Matter 2011 proceeding
