Seasonal infertility remains a major challenge in pig production and is influenced by environmental conditions and sow parity. This study aimed to identify in-barn heat load (HL), light variability (LV), and parity as farm-specific predictors of farr...

A graph is even (resp. odd) if all its vertex degrees are even (resp. odd). We consider edge coverings by prescribed number of even and/or odd subgraphs. In view of the 8-Flow Theorem, a graph admits a covering by three even subgraphs if and only if...

We interpret the lack of large-angle temperature correlations and the even-odd parity imbalance observed in the cosmic microwave background (CMB) by COBE, WMAP and Planck satellite missions as a possible stringy signal ultimately stemming from a comp...

Equivariant graph neural networks encode the $\mathrm{E}\left(3\right)$ symmetries that molecular force fields must obey, yet they are often trained against geometric objectives whose own symmetry is rarely examined. We develop a symmetry-sensitive diagnostic protocol tha...

Sr${}_2$RuO${}_4$ and Fe-pnictide superconductors belong to the same point group symmetry $D_{4h}$. Many experimental data confirm odd pairs in Sr${}_2$RuO${}_4$ and even pairs in Fe-pnictides, but opposite conclusions also exist. Recent NMR results of Pustogow et al., which...

Background/Objectives: Postpartum depression (PPD) is a clinically important perinatal mental health condition affecting maternal functioning and early mother–infant interaction. Prospective studies using clinically diagnosed PPD outcomes while...

Malaria infection during pregnancy is a major public health problem in sub-Saharan Africa. The World Health Organization (WHO) recommends that gestational and congenital malaria can be prevented by using intermittent preventive treatment of malaria i...

Recently, operations research, especially linear integer-programming, is used in various grids to find optimal paths and, based on that, digital distance. The 4 and higher-dimensional body-centered-cubic grids is the nD ($n\ge 4$) equivalent of the 3D...

The purpose of the study was to investigate 1: overall knowledge of pelvic organ prolapse (POP) and urinary incontinence (UI) as well as knowledge, attitudes, and practice of pelvic floor muscle exercise (PFME); and 2: the association of these factor...

The current study investigated the trends and factors associated with the unmet need for family planning (FP) for limiting and spacing births among married Tanzanian women between 1999 and 2016. The study used Tanzania Demographic and Health Survey (...
