Cholesteryl-6-O-acyl-α-d-glucopyranoside ofHelicobacter pylorirelate to relative lysophospholipid content [PDF]

FEMS Microbiology Letters, 2005
The presence of cholesteryl glucosides and high levels of lysophospholipids are elements making the cell wall of Helicobacter pylori unique. In this study, we have investigated the relationship between lysophospholipid content and cholesteryl glucoside composition of variants of 6 clinical isolates.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Regressions between molt period δD_fur and growing season δD_precip or latitude at the collection sites.

, 2012
The δDfur values (site mean ± standard deviation) of males collected during the molt period varied significantly with latitude of capture (panel A) and predicted growing season δDprecip at the location of capture (panel B).

Optimization of the Production of Rubber Compounds Using Mathematical Models

Advanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Induction of opsonic antibodies to the γ-d-glutamic acid capsule ofBacillus anthracisby immunization with a synthetic peptide-carrier protein conjugate [PDF]

FEMS Immunology & Medical Microbiology, 2004
The capsule of Bacillus anthracis, a polymer of gamma-D-glutamic acid, functions as a virulence determinant and is a poor immunogen. In this study we show that antibodies reactive with the B. anthracis capsule can be elicited in mice by immunization with a conjugate consisting of a synthetic gamma-D-glutamic acid nonamer peptide (gamma-D-glu9 ...
