Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

H∞ Sliding Mode Control: A Recent Review of Applications and Design Methods

open access: yesIEEE Access
The $H_{\infty }$ Sliding Mode Control ( $H_{\infty }$ SMC) approach was introduced at the onset of this millennium as a proficient strategy integrating sliding mode and $H_{\infty }$ control principles to leverage their robust attributes while ...

Complexity adaptation in H.264/AVC video coder for static cameras [PDF]

open access: yes, 2009
H.264/AVC uses variable block size motion estimation (VBSME) to improve coding gain. However, its complexity is significant and fixed regardless of the required quality or of the scene characteristics. In this paper, we propose an adaptive complexity

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

H-mode accelerating structures with permanent-magnet quadrupole beam focusing

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
We have developed high-efficiency normal-conducting rf accelerating structures by combining H-mode resonator cavities and a transverse beam focusing by permanent-magnet quadrupoles (PMQ), for beam velocities in the range of a few percent of the speed of ...

Efficient intra- and inter-mode selection algorithms for H.264/AVC [PDF]

open access: yes, 2004
H.264/AVC standard is one of the most popular video formats for the next generation video coding. It provides a better performance in compression capability and visual quality compared to any existing video coding standards.

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

open access: yesFEBS 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 ...

Gyrokinetic simulation of eigenmode GAM in EAST H-mode plasma

open access: yesNuclear Fusion
Gyrokinetic simulations based on the Gyrokinetic Toroidal Code are conducted to investigate the geodesic acoustic mode (GAM) physics in the pedestal of EAST H-mode discharge $\#$ 74036 (Zhou et al 2018 Nucl. Fusion 58 106009).

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Experimental observation and edge characteristics of EDA H-mode on the HL-3 tokamak

open access: yesNuclear Fusion
The enhanced ${D_\alpha }$ (EDA) H-mode features high energy confinement together with the absence of edge localized modes (ELMs) and impurity accumulation, making it highly attractive for fusion reactors. The EDA H-mode has been observed recently in the
