Multi-fold fermionic and bosonic states in topologically non-trivial TiPd.

The topological properties of the A15-type compound TiPd reveal a complex landscape of multi-fold fermionic and bosonic states, as uncovered through calculations within the framework of density functional theory (DFT). The electronic band structure shows multi-fold degenerate crossings at the high-symmetry point R near the Fermi level, which evolves into 4-fold and 8-fold degenerate fermionic states upon the introduction of spin-orbit coupling (SOC). Likewise, the phononic band structure features multi-fold degenerate bosonic crossings at the same R point.

Assessing the efficacy of synthetic compounds foliar sprays in alleviating terminal heat stress in late-sown wheat ().

Detrimental effects of terminal heat stress could be mitigated by exogenous application of synthetic compounds by preserving cell membrane integrity and protecting against oxidative damage. A field experiment was conducted to test the application of seven synthetic compounds on wheat growth traits: (1) thiourea (20 mM and 40mM); (2) potassium nitrate (1% and 2%); (3) sodium nitroprusside (400 μg mL-1 and 800μg mL-1 ); (4) dithiothreitol (25 ppm and 50ppm); (5) salicylic acid (100 ppm and 200ppm); (6) thioglycolic acid (200 ppm and 500ppm); and (7) putrescine (4 mM and 6mM). These compounds were applied at the anthesis and grain-filling stages to enhance physio-biochemical traits and yield attributes of wheat (Triticum aestivum ) cvs GW-11 and GW-496 under terminal heat stress.

Imaging in atypical van der knaap disease with subependymal nodular heterotopia: A case report.

Here, we discuss a rare and to our knowledge, the first case of an atypical Van der Knaap's disease in a 6-year-old boy who presented with motor difficulties, developmental delay, cognitive impairment, seizures. The objective of this report is to highlight its unusual findings on MRI including internal capsule, brainstem, cerebellum involvement; subependymal nodular heterotopia, subependymal cysts, cortical laminar necrosis along with typical findings of megalencephalic leukoencephalopathy and subcortical cysts. The study also underscores the clinical implications of this complex pathology, with emphasis on comprehensive neuroradiological evaluation for atypical presentations to guide better diagnostic and management outcomes.

Assessing Post-traumatic Stress Disorder and Social Determinants Among COVID-19 Case-Contact Dyads in Household Settings.

Background: Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The COVID-19 outbreak raised several public and mental health concerns including tremendous psychological distress.

Aim: To assess post-traumatic stress disorder (PTSD) among COVID-19-positive patients and household contacts and to determine the socio-demographic factors associated with PTSD in the study population.

Exergetic investigation of the influence of injector location in HCCI engines utilizing DEE as pilot fuel and biogas as primary fuel.

To address the global demand for sustainable energy, integrating biogas into internal combustion engines is becoming more important. Homogeneous Charge Compression Ignition (HCCI) engines, known for high efficiency and low emissions, offer a promising solution. This study investigates the optimal injector location for using biogas in HCCI engines, with diethyl ether (DEE) as the pilot fuel, evaluating three positions: (i) at the port, (ii) 6 cm away (Manifold 1), and (iii) 10 cm away (Manifold 2).
