In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Single-Crystalline Si Stacked AlGaN/GaN High-Electron-Mobility Transistors with Enhanced Two-Dimensional Electron Gas Density

Micromachines
High-electron-mobility transistors (HEMTs) are characterized by the formation of a two-dimensional electron gas (2DEG) induced by the polarization effects.

Stacking sensitive topological phases in a bilayer Kane-Mele-Hubbard model at quarter filling

, 2019
Layered quasi two dimensional systems have garnered huge interest both in the advancement of technology and in understanding emergent physics such as unconventional superconductivity, topological phases. In particular, the study of topological properties

Entropy and biological systems: experimentally-investigated entropy-driven stacking of plant photosynthetic membranes [PDF]

, 2014
According to the Second Law of thermodynamics, an overall increase of entropy contributes to the driving force for any physicochemical process, but entropy has seldom been investigated in biological systems.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Mapping the air temperature in China from time-normalized MODIS land surface temperature data via zone-based stacking ensemble models

Geo-spatial Information Science
High-resolution near-surface air temperature (Ta) data are important for studies on human life and plant. Remote sensing offers an effective means to acquire spatially continuous Ta over large areas.

Research on Strawberry Quality Grading Based on Object Detection and Stacking Fusion Model

IEEE Access, 2023
Strawberry quality grading helps producers to better manage inventory, transportation and sales, and improve product market competitiveness. Currently, this work is mostly carried out by manual grading, which is not only inefficient, but also relies on ...

A Simultaneous Stacking and Deblending Algorithm for Astronomical Images

, 2010
Stacking analysis is a means of detecting faint sources using a priori position information to estimate an aggregate signal from individually undetected objects. Confusion severely limits the effectiveness of stacking in deep surveys with limited angular

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
