Background: Sleep deprivation leads to decreased performance, alertness and degradation in the health status of a person. Often the person remains unaware of the reduced alertness and may end up taking inaccurate decisions. There was a need to study the sleep duration of college goers and to study the effect of total night-time sleep duration on daytime Electroencephalogram (EEG) characteristics.

Methods: This study aimed to investigate the role of the estrogen-induced ERα-ERRα-SPP1 signaling axis in relation to mammary tumorigenesis in female mice exposed to simulated GCR (GCRsim) at 100-110 days post-exposure.
This paper draws from qualitative research undertaken with the mothers and primary caregivers of children aged under 5 years old and in recovery from severe acute malnutrition (SAM), as well as other community members, across three study sites in Kenya, Zambia, and Zimbabwe. The paper highlights how nutrition-related stigma is constructed and enacted in complex ways, by multiple actors and across diverse settings. Adopting an intersectional approach, the paper identifies how stigma emerges at the intersections of social identity, especially age, gender, and associated beliefs about women's, and especially young women's, assumed (in)capacity to care.

- The study focuses on detecting multijet signatures from proton-proton collisions at a high energy of 13 TeV, analyzing a dataset totaling 128 fb^{-1}.
- A special data scouting method is utilized to pick out events with low combined momentum in jets.
- This research is pioneering in its investigation of electroweak particle production in R-parity violating supersymmetric models, particularly examining hadronically decaying mass-degenerate higgsinos, and it broadens the limits on the existence of R-parity violating top squarks and gluinos.
Article Synopsis
- Superhydrophobic surfaces with hierarchical micro/nanostructures, like the developed O-Ph-POSS on fluorinated graphene, achieve high water contact angles (152°) and low surface energy (5.6 mJ/m²), making them highly robust and effective in water-repelling applications.
- The O-Ph-POSS-FG hybrid demonstrated remarkable oil absorption (200-500 wt%) and was successfully used to coat polyurethane sponges, achieving oil-water separation efficiencies of 90%-99%, even after multiple cycles.
- Durability tests showed that the sponges maintained superhydrophobic properties over time, retaining effective water contact angles and separation efficiency after one year and multiple mechanical stress tests.
