Bat Species Comparisons Based on External Morphology: A Test of Traditional versus Geometric Morphometric Approaches. [PDF]

open access: yesPLoS ONE, 2015
External morphology is commonly used to identify bats as well as to investigate flight and foraging behavior, typically relying on simple length and area measures or ratios. However, geometric morphometrics is increasingly used in the biological sciences

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

open access: yesMolecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Construction of Local-Shape-Controlled Quartic Generalized Said-Ball Model

open access: yesMathematics, 2023
Said-Ball curves and surfaces are extensively applied in the realm of geometric modeling. Their appearance is only decided by the control points, which produces a great deal of inconvenience for the shape design of sophisticated products.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Data-Driven Research on the Matching Degree of Eyes, Eyebrows and Face Shapes

open access: yesFrontiers in Psychology, 2019
There is a close relationship between the attractiveness of the face and the facial features. The shape of the facial features determines the level of attractiveness, in which the eyes and eyebrows are particularly vital.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

On the Probabilistic Shaping and Geometric Shaping in Optical Communication Systems [PDF]

open access: yesIEEE Access, 2019
We introduce and compare typical shaping schemes suitable for optical communications. The geometrically shaped-quadrature amplitude modulation (GS-QAM) formats are characterized by the non-equidistant spacing of constellation points, transmitted uniformly, and applied to improve system capacity.

Mathematical expression method for geometric shape of toroidal propeller

open access: yesZhongguo Jianchuan Yanjiu
ObjectivesThe toroidal propeller can effectively reduce tip vortex leakage due to its unique shape, which is beneficial for reducing hydrodynamic noise and improving propulsion efficiency. However, its complex shape also makes it challenging to model its
