Form factors for $B-->\pi l\nu$ decay in a model constrained by chiral symmetry and quark model [PDF]

, 2000
The form factors for the $B-->\pi$ transition are evaluated in the entire momentum transfer range by using the constraints obtained in the framework combining the heavy quark expansion and chiral symmetry for light quarks and the quark model.

SPECIFIC FEATURES OF DEFORMATION OF THE CONTINENTAL AND OCEANIC LITHOSPHERE AS A RESULT OF THE EARTH CORE NORTHERN DRIFT

Геодинамика и тектонофизика, 2015
Drifting and submeridional compression of the continental and oceanic lithosphere, both with the northward vector (Figure 1) are revealed at the background of various directions of horizontal displacement combined with deformations of horizontal ...

A reconfigurable dual‐band low noise amplifier for 5G in 65‐nm CMOS

Electronics Letters, 2023
In this paper, a reconfigurable low noise amplifier (LNA) is proposed for 5G dual‐bands in a 65‐nm CMOS process. The reconfigurable function of LNA is realized by designing reconfigurable matching networks composed of transformers and MOS transistor ...

Regge-cascade hadronization [PDF]

, 2006
We argue that the evolution of coloured partons into colour-singlet hadrons has approximate factorization into an extended parton-shower phase and a colour-singlet resonance--pole phase.

Les adverbiaux prépositionnels en dans : exploration en corpus de la notion de contenance

Corela, 2010
This paper provides a description of the notional meanings of the French preposition dans (‘in’) in the construction [Dans NPy, Sx], where the Ground y is expressed by the extra-predicative PP [Dans NP], and the Figure x by a part or by the whole ...

The $\sigma$ meson in a nuclear medium through two pion photoproduction

, 2002
We present theoretical results for $(\gamma, \pi^0 \pi^0)$ production on nucleons and nuclei in the kinematical region where the scalar isoscalar $\pi \pi$ amplitude is influenced by the $\sigma$ pole. The final state interaction of the pions modified by

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Spindle Angle Measurements

Bio-Protocol, 2013
Spindle angles measures derive from the measures of spindle poles positions that were taken from fixed and immunostained adherent cells. To determine spindle angles (α), z-stack images of metaphasic cells immunostained with anti γ-tubulin (spindle poles)

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
