SUSY naturalness without prejudice

, 2013
Unlike the Standard Model (SM), supersymmetric models stabilize the electroweak (EW) scale $v$ at the quantum level and {\it predict} that $v$ is a function of the TeV-valued SUSY parameters ($\gamma_\alpha$) of the UV Lagrangian.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Slash-Weighted Lindley Distribution: Properties, Inference, and Applications

Mathematics, 2023
The slash-weighted Lindley model is introduced due to the need to obtain a model with more kurtosis than the weighted Lindley distribution. Several expressions for the pdf of this model are given.

Luminosity Functions of Gamma-Ray Burst Afterglows

, 2007
Aims: Use the standard fireball model to create virtual populations of gamma-ray burst afterglows and study their luminosity functions. Methods: We randomly vary the parameters of the standard fireball model to create virtual populations of afterglows.

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

FEBS 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.

Some considerations in connection with Kurepa's function [PDF]

, 2004
In this paper we consider the functional equation for factorial sum and its particular solutions (Kurepa's function $K(z)$ \cite{Kurepa_71} and function $K_{1}(z)$).

Ewald methods for inverse power-law interactions in tridimensional and quasi-two dimensional systems

, 2010
In this paper, we derive the Ewald method for inverse power-law interactions in quasi-two dimensional systems. The derivation is done by using two different analytical methods.

Functional inequalities for the incomplete gamma function

Journal of Mathematical Analysis and Applications, 2012
Let \(f_a(x)= \Gamma(a,x)/\Gamma(a,0)\), where \(\Gamma(a,x)\) denotes the incomplete gamma function \((a,x> 0)\). The authors prove various new functional inequalities for \(f_a(x)\). For example, they study the double inequality \[ f_a(S_p(x_1,\dots, x_n))\leq f_a(x_1)\cdots f_a(x_n)\leq f_a(S_q(x_1,\dots, x_n)), \] where \(S_t\) is the power sum of ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

New upper and lower bounds for the upper incomplete gamma function

Results in Applied Mathematics
Some new upper and lower bounds for the upper incomplete gamma function Γ(a,x) are presented. Some of the bounds are given for all real x>0 and some are for only certain combinations of a and x.
