A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

From Pathogens to Partners: The Beginnings of Gut Microbiota Research

open access: yesApplied Sciences
The investigation of the human intestinal microbiota has rapidly become one of the most dynamic and interdisciplinary fields in modern biomedical science, and for good reasons.

SELF-EQUALITY AS A STRATEGY OF SPONTANEOUS TEXT GENERATION

open access: yesВестник Кемеровского государственного университета, 2017
The article deals with the results of the psycholinguistic experiment which prove the influence of the self-equality strategy in the process of spontaneous reaction text generation as a reaction on the stimulus “human life”.

Possibility of spontaneous CP violation in the nonminimal supersymmetric standard model with two neutral Higgs singlets

open access: yes, 2002
A supersymmetric standard model with two Higgs doublets and two Higgs singlets is investigated if it can accommodate the possibility of spontaneous CP violation.

Photon-pair generation by non-instantaneous spontaneous four-wave mixing [PDF]

open access: yes, 2017
We present a general model, based on a Hamiltonian approach, for the joint quantum state of photon pairs generated through pulsed spontaneous four-wave mixing, including nonlinear phase-modulation and a finite material response time.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Analysis of harmonic generation in planar and elliptic bi-harmonic undulators and FELs

open access: yesResults in Physics, 2019
We present a phenomenological model for single-pass FEL radiation power and bunching evolution in planar and elliptic undulators with two polarizations of the emitted radiation; the models allows for the suppression of low harmonics in the spectrum.

Spontaneous current generation in the gapless 2SC phase

open access: yes, 2006
It is found that, except chromomagnetic instability, the gapless 2SC phase also exhibits a paramagnetic response to the perturbation of an external color neutral baryon current.

Spontaneous generation of modular invariants [PDF]

open access: yesMathematics of Computation, 1996
It is possible to compute j ( τ ) j(\tau ) and its modular equations with no perception of its related classical group structure except at ∞ \infty . We start by taking, for p p prime, an unknown “ p p -Newtonian” polynomial equation g
