Insights into the Dynamics and Binding Mechanisms of the Alkhumra Virus NS2B/NS3 Protease: A Molecular Dynamics Study

open access: yesAdvanced Theory and Simulations, EarlyView.
The ΔRMSF$\Delta {\rm RMSF}$ analysis reveals significant flexibility differences between free NS3 and the NS2B/NS3 complex, with notable deviations in specific regions. Key residues driving NS2B binding are identified, and the protonation state of catalytic serine affects oxyanion hole formation.

Antler tine homologies and cervid systematics: A review of past and present controversies with special emphasis on Elaphurus davidianus

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 5-28, January 2023., 2023
Abstract Antlers are the most conspicuous trait of cervids and have been used in the past to establish a classification of their fossil and living representatives. Since the availability of molecular data, morphological characters have generally become less important for phylogenetic reconstructions.

High‐Performance Polymer‐derived Ceramics in LCD 3D Printing

open access: yesAdvanced Science, EarlyView.
This study highlights the potential of silicon oxycarbide‐based formulations for producing polymer‐derived ceramics with superior properties via LCD 3D printing. VMM‐based ceramics demonstrate a remarkable 50‐fold increase in compressive strength (up to 17 MPa) compared to SPR‐684, along with exceptional high‐temperature survivability (up to 1500 °C ...

Come together over me: Cells that form the dermatocranium and chondrocranium in mice

open access: yesThe Anatomical Record, EarlyView., 2023
Abstract Most bone develops either by intramembranous ossification where bone forms within a soft connective tissue, or by endochondral ossification by way of a cartilage anlagen or model. Bones of the skull can form endochondrally or intramembranously or represent a combination of the two types of ossification.

Integrating spatial and temporal approaches for explaining bicycle crashes in high-risk areas in Antwerp (Belgium) [PDF]

open access: yes, 2019
The majority of bicycle crash studies aim at determining risk factors and estimating crash risks by employing statistics. Accordingly, the goal of this paper is to evaluate bicycle-motor vehicle crashes by using spatial and temporal approaches to ...
