New Accurate Approximation for Average Error Probability

IEEE Access, 2021
This paper proposes new accurate approximations for average error probability (AEP) of a communication system employing either M-phase-shift keying (PSK) or differential quaternary PSK with Gray coding (GC-DQPSK) modulation schemes over generalized ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Valorization of trout skins for a circular bioeconomy: Ecological leather production and anaerobic co-digestion of tanning effluents with trout byproducts (Morocco)

Environmental Challenges
With growing environmental concerns, sustainable alternatives in the leather industry are crucial. This study explores the potential of trout skins as a raw material to produce ecological leather and evaluates the biodegradability of the co-digestion of ...

Truncation error bounds for modified continued fractions with applications to special functions

Numerische Mathematik, 1989
Let \(K(a_ n,1;x_ 1)\) be a limit-periodic modified continued fraction with \(\lim_{n\to \infty}a_ n=a\in {\mathbb{C}}-(-\infty,1/4)\) and n-th approximant \[ g_ n=S_ n(x_ 1)=a_ 1/1+a_ 2/1+...+a_{n- 1}/1+a_ n/(1+x_ 1), \] where \(x_ 1\) denotes the smaller (in modulus) of the two fixed points of \(T(w)=a/(1+w).\) Further, let \(f_ n=S_ n(0)\) be the n ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Approximation of Integrable Functions by Modified Barbosu Operators [PDF]

International Journal of Mathematical, Engineering and Management Sciences
This paper presents an approximation method of integrable functions using a modified Barbosu operator, aimed at improving the rate of convergence in function approximation on the interval [0,1]. By introducing a suitable adjustment in the weight function,

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
