Prediction of air concentration in stepped spillways using data-oriented methods [PDF]

محیط زیست و مهندسی آب
The high flow velocity and the pressure reduction in the spillways cause damage to the spillways. In the present research, the application of Gaussian Process Regression (GPR) and Support Vector Machine (SVM) was investigated for predicting air ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

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 ...

Two-Step Aminoacylation of tRNA without Channeling in Archaea [PDF]

Journal of Molecular Biology, 2011
Catalysis of sequential reactions is often envisaged to occur by channeling of substrate between enzyme active sites without release into bulk solvent. However, while there are compelling physiological rationales for direct substrate transfer, proper experimental support for the hypothesis is often lacking, particularly for metabolic pathways involving

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Correction of Channel Imbalance for MIMO SAR Using Stepped-Frequency Chirps

International Journal of Antennas and Propagation, 2014
To simultaneously achieve two-dimensional high resolution and wide swath in synthetic aperture radar (SAR), azimuth MIMO structure combined with stepped-frequency chirp signals was developed via splitting the antenna into N subapertures.

Electrostatically-Doped Hetero-Barrier Tunnel Field Effect Transistor: Design and Investigation

IEEE Access, 2018
In this paper, an electrostatically-doped hetero-barrier tunnel-field-effect-transistor (EDHet-TFET) based on stepped broken-gap (type-III) is simulated, investigated, and compared with the conventionally-doped stepped broken-gap hetero-barrier TFET (Het-

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Multi-Channel Step FinFET With Spacer Engineering

IEEE Access
Multi-channel FinFET ( $\text{M}_{\textbf {ch}}$ -FinFET) is an emerging device having promising use due to its excellent driving capability. In this paper, we have investigated the significance of multiple channels of FinFET configuration. We have examined the performance of the multi-channel-based step FinFET ( $\text{M}_{\textbf {ch}}$ - step FinFET)

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Optical Design and Investigation of a Dual-Interference Channels and Bispectrum Static Fourier-Transform Imaging Spectrometer Based on Stepped Micro-Mirror

IEEE Access, 2021
We demonstrate a novel tempo-spatial mixed-modulation Fourier-transform infrared imaging spectrometer. The static interference channel based on a stepped micro-mirror contributes a compact system with high stability.
