Stochastic Simulation of Process Calculi for Biology

open access: yes, 2010
Biological systems typically involve large numbers of components with complex, highly parallel interactions and intrinsic stochasticity. To model this complexity, numerous programming languages based on process calculi have been developed, many of which ...

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

open access: yesFEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

A middle aged women with bilateral staghorn complete calculi

open access: yesThe Pan African Medical Journal, 2014
A 50-year-old woman presented with a 2-years history of chronic flanc and hematuria. Plain abdominal radiography was performed showing bilateral complete staghorn calculi.

Systematic construction of natural deduction systems for many-valued logics [PDF]

open access: yes, 1993
A construction principle for natural deduction systems for arbitrary, finitely-many-valued first order logics is exhibited. These systems are systematically obtained from sequent calculi, which in turn can be automatically extracted from the truth tables

Efficacy Evaluation of the Phytotherapeutic Drug Canephron N in the Complex Treatment of Patients with Urolithiasis Using Extracorporeal Shock Wave Lithotripsy [PDF]

open access: yes, 2018
The study objective was to analyse the effect of the herbal drug Canephron N, namely, its ability to potentiate the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of patients with urolithiasis (UL) and prevent recurrence of ...

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

open access: yesFEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

All bicovariant differential calculi on Glq(3,C) and SLq(3,C)

open access: yes, 1994
All bicovariant first order differential calculi on the quantum group GLq(3,C) are determined. There are two distinct one-parameter families of calculi.

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Tool support for reasoning in display calculi [PDF]

open access: yes, 2016
We present a tool for reasoning in and about propositional sequent calculi. One aim is to support reasoning in calculi that contain a hundred rules or more, so that even relatively small pen and paper derivations become tedious and error prone.

On the Correspondence between Display Postulates and Deep Inference in Nested Sequent Calculi for Tense Logics

open access: yes, 2011
We consider two styles of proof calculi for a family of tense logics, presented in a formalism based on nested sequents. A nested sequent can be seen as a tree of traditional single-sided sequents.
