by Shoaib Hassan, Sarfraz Ali Shad

Green lacewing, Chrysoperla carnea (Stephens) is a generalist predator used as a biological control agent in agro ecosystems. In order to use chemical and biological control in an integrated way, it is advantageous to know about natural enemy resistance response to a selected chemical. To determine C. carnea spirotetramat resistance potential, a population collected from the field was selected in the laboratory. Then we determined how spirotetramat resistance... Читать дальше...

This study assessed the resilience of nurses in Saudi Arabia during the corona virus 2019 (COVID-19) pandemic and examined its influence on their quality of life (QOL). A sample of 356 nurses was surveyed in this quantitative, cross-sectional study using the Resilience Scale for Nurses and the World Health Organization Quality of Life (WHOQOL-BREF) from October 2020 to March 2021. The nurses reported the highest resilience score on “situational pattern”, while... Читать дальше...

Improved lightweight YOLOv5 based on ShuffleNet and its application on traffic signs detection

by Liwei Liu, Lei Wang, Zhuang Ma

Traffic signs detection is an important and challenging task in intelligent driving perception system. This paper proposes an improved lightweight traffic signs detection framework based on YOLOv5. Firstly, the YOLOv5’s backbone is replaced with ShuffleNet v2, which simplifies the calculation complexity and reduces the parameters of backbone network. Secondly, aiming at the problem of inconspicuous traffic sign characteristics in complex road environment... Читать дальше...

Parenting stress, dyadic coping and endocrine markers of stress and resilience in foster and biological mothers

Foster parents have been shown to report higher levels of parenting stress but also more dyadic coping (DC) behaviors in their partnership than biological parents, which might be an important protective factor that helps them cope with daily stressors. Here, we examined how parenting stress and DC are related in foster and biological parents and whether these are reflected in long-term alterations of hypothalamic-pituitary-adrenocortical (HPA) axis activity.

The genome of living cells is constantly challenged by DNA lesions that interfere with cellular processes such as transcription and replication. A manifold of mechanisms act in concert to ensure adequate DNA repair, gene expression, and genome stability. Bulky DNA lesions, such as those induced by UV light or the DNA-damaging agent 4-nitroquinoline oxide, act as transcriptional and replicational roadblocks and thus represent a major threat to cell metabolism.
