by Sharon Teitler Regev, Tchai Tavor

The global health crisis initiated by the COVID-19 pandemic triggered unparalleled economic upheavals. In this comprehensive study of 16 countries categorized by their infection rates, we scrutinize the impact of a range of variables on stock market indices and calculate four critical ratios derived from those variables. Our regression analyses reveal striking differences in how the variables influenced stock indices in countries with low and high infection rates. Читать дальше...

Effects of Pieris japonica (Ericaceae) dominance on cool temperate forest altered-understory environments and soil microbiomes in Southern Japan

En

by Yuji Tokumoto, Ayumi Katayama

The number of plants unpalatable to deer increases with increasing deer numbers. In the Kyushu Mountain area of Southern Japan, Pieris japonica (Ericaceae), an unpalatable shrub, has become the monodominant vegetation under evergreen conifer and deciduous broad-leaved tree stands. The monodominance of unpalatable plants in the understory has potential advantages and drawbacks; however, the effects of Pieris dominance are not well understood. To assess the effects of P.

COVID-19 masks and limited number of shoppers as determinants of shop assistants’ (dis)honesty

by Maciej Koscielniak, Dorota Marciniak, Dariusz Doliński

Previous laboratory and field studies have demonstrated that the dishonesty of commercial transaction participants may depend on subtle cues. In this field study conducted on a sample of 216 shop assistants in Poland, we planned to demonstrate that coronavirus disease-related factors could result in an increased propensity for dishonesty among shop assistants. This investigation is unique in its application of social psychological... Читать дальше...

Changes in instrumental activities daily living limitations and their associated factors according to gender in community-residing older adults: A longitudinal cohort study

En

by SeolHwa Moon, Eunmi Oh, Daum Chung, Gwi-Ryung Son Hong

Background

Increases in dependence among older adults cause increases in care needs and social care burden. Instrumental activities of daily living (IADL) are often used to assess the independence of older adults residing in communities. Various factors affect IADL limitations, but few studies confirm gender differences in IADL limitations in older adults. This study explored the changes in incidence of IADL limitations across 14...

Sex differences in growth and mortality in pregnancy-associated hypertension

by Jess C. Hercus, Katherine X. Metcalfe, Julian K. Christians

Background

It is hypothesized that male fetuses prioritize growth, resulting in increased mortality, whereas females reduce growth in the presence of adversity. Preeclampsia reflects a chronic condition, in which fetuses have the opportunity to adjust growth. If females reduce their growth in response to preeclampsia, but males attempt to maintain growth at the cost of survival, we predict that differences in birthweight between... Читать дальше...

Scenario analysis on co-benefits of air pollution control and carbon reduction in Yangtze River Delta based on STIRPAT model

In a changing climate, it is vital to focus on the co-benefits of the pollution control and carbon emission reduction. Based on calculation of emission equivalent, the synergy coefficient is further calculated to quantitatively analyze the co-benefits of air pollution control and carbon reduction in the Yangtze River Delta; Scenario analysis in co-benefits in the Yangtze River Delta from 2026–2035 is thoroughly proposed...

Performance enhancement and PAPR reduction for MIMO based QAM-FBMC systems

En

by Emad S. Hassan

Filter Bank Multi-Carrier (FBMC) is attracting significant interest as a multi-carrier modulation (MCM) approach for future communication systems. It offers numerous advantages in contrast to Orthogonal Frequency Division Multiplexing (OFDM). Nonetheless, similar to many other MCM techniques, FBMC encounters a significant challenge with a high Peak-to-Average Power Ratio (PAPR). Additionally, incorporating Multiple-Input and Multiple-Output (MIMO) into FBMC presents heightened... Читать дальше...

Patterns in refractive error and treatment delay in keratoconus–An Australian study

Plos.org 
En

by Samantha Bobba, Alanna Wood, John Males, Yves Kerdraon

Keratoconus is the most common primary corneal ectasia and is associated with significant morbidity. In its early stages, keratoconus is often asymptomatic, making the identification of subclinical disease challenging. Refractive error is a parameter that is documented at most routine optometry visits, yet interestingly, changes in refraction of keratoconic patients over time have not yet been studied and compared with the general population.

F-actin coordinates spindle morphology and function in Drosophila meiosis

Plos.org 
En

by Benjamin W. Wood, Xingzhu Shi, Timothy T. Weil

Meiosis is a highly conserved feature of sexual reproduction that ensures germ cells have the correct number of chromosomes prior to fertilization. A subset of microtubules, known as the spindle, are essential for accurate chromosome segregation during meiosis. Building evidence in mammalian systems has recently highlighted the unexpected requirement of the actin cytoskeleton in chromosome segregation; a network of spindle actin filaments appear to regulate many aspects of this process.
