Case Studies in Thermal EngineeringThe core idea of similarity theory is to use the scaled model to replace prototype for equivalent experiments, to obtain approximate solutions to the research problems based on saving research costs. The major goal of this work is to propose a new steady-

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Integers, 2015 In 1989, Erdős conjectured that for a sufficiently large $n$ it is impossible to place $n$ points in general position in a plane such that for every $1\le i \le n-1$ there is a distance that occurs exactly $i$ times. For small $n$ this is possible and in his paper he provided constructions for $n\leq 8$.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

THE CONFIGURATION OF STENDOMYCIDINE
The Journal of Antibiotics, 1970 The absolute configuration of stendomycidine (I), a constituent of the peptide antibiotic stendomycin, was determined. Optical rotatory dispersion (ORD) measurements showed the configuration at the α-carbon atom to be that of an L-amino acid. Degradation of stendomycidine with N-bromosuccinimide yielded 2-methylimino-3-methyl-hexahydropyrimidine-4 ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Study on the Aeroelastic Characteristics of a Large-Span Joined-Wing Solar-Powered UAV
AerospaceWhen a joined-wing configuration is applied to the design of solar-powered UAVs, the increasing span amplifies aeroelastic effects, while structure complexity poses greater challenges to computational effectiveness during the conceptual design phase ...

Heat Transfer Enhancement using Combined Microchannel with Vertical Rectangular Micro Fins
Nigerian Journal of Technological Development, 2023 This paper focuses on the numerical optimisation of a combined hybrid microchannel heat sink with rectangular solid fins. The axial length and volume are fixed, and external structure is allowed to vary. The simulation was performed on an elemental unit

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
