Evidence for Non‐Stationarity in the GEV Shape Parameter When Modeling Extreme Rainfall

Water Resources Research
It is now well established that climate change is increasing the intensity of extreme rainfall. What is less well established is how best to model these changes.

具有简单G3条件的可调曲线曲面(Adjustable curves and surfaces with simple G3 conditions)

Zhejiang Daxue xuebao. Lixue ban, 2016
In order to make curves and surfaces have adjustable shape and simple G3 conditions,a kind of EI functions is defined recursively. Based on them, we construct EI curves and surfaces,which have the most properties of Bézier curves and surfaces. Owe to the

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Simple Gamma Random Number Generator for Arbitrary Shape Parameters [PDF]

This paper proposes an improved gamma random generator. In the past, a lot of gamma random number generators have been proposed, and depending on a shape parameter (say, alpha) they are roughly classified into two cases: (i) alpha lies on the interval (0,

Iterated function systems and shape representation [PDF]

, 1990
We propose the use of iterated function systems as an isomorphic shape representation scheme for use in a machine vision environment. A concise description of the basic theory and salient characteristics of iterated function systems is presented and from

Study on Dynamic Factors of Damped Beam Members Under Exponential Attenuation Loading

Buildings
Blast loading is characterized as an impact loading with exponential attenuation, while damping serves as an intrinsic parameter that affects the vibration effect of beam members. The linear attenuation for simplified blast loading and undamped situation
