Lightlike Geometry of Leaves in Indefinite Kenmotsu Manifolds
Cubo, 2011 In this paper, we study some aspects of the geometry of leaves of integrable distributions of lightlike hypersurfaces in indefinite Kenmotsu manifolds, tangent to the structure vector field.

Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease
Arthritis &Rheumatology, EarlyView.Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Nonhuman Mobilities and Multispecies Border Regimes in (Post‐)Colonial Southern Africa**
Berichte zur Wissenschaftsgeschichte, EarlyView.This article explores how borders in Southern Africa—such as Namibia's internal veterinary and settler border (Red Line) and national borders between Namibia, South Africa, and Botswana—functioned not only as territorial dividers but as tools to shape colonial and postcolonial multispecies hierarchies. These borders regulated human and animal movement,

Killing Vector Fields of Invariant Metrics
GeometryWe study the existence of Killing vector fields for right-invariant metrics on low-dimensional Lie groups. Specifically, Lie groups of dimension two, three and four are considered. Before attempting to implement the differential conditions that comprise Killing’s equations, the metric is reduced as much as possible by using the automorphism group of ...

What Makes an “Ideal” Cell Line for Recombinant Adeno‐Associated Virus Production?
Biotechnology and Bioengineering, EarlyView.Several host cell types have been used to produce rAAVs to date. Cell line‐specific traits that are beneficial in the context of rAAV manufacturing are reviewed here, with the goal of developing a consensus on the ‘ideal’ characteristics that an rAAV production host should possess (created with Biorender.com).

A necessary and sufficient condition for a vector field to be Killing
, 1979 Lynge (see (4)), proved that X vector field on a compact and connected manifold M, is Killing in a Riemannian metric g, if and only if there exist k complete vector fields X1 , ... , Xk; such that: 1) The fl.ows of the Xi are a11 periodic, 2) [X;, X;]

Biotechnology and Bioengineering, EarlyView.Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.

Biotechnology and Bioengineering, EarlyView.Lifecycle perspective on cell and gene therapy manufacturing challenges and enabling GMP solutions. ABSTRACT Cell and gene therapies (CGTs) are revolutionizing modern medicine; however, making these advanced medicines scalable and readily available to commercial manufacturers worldwide is a major challenge. The number of approved CGT products continues

Hydrodynamic Killing vector fields on surfaces
Journal of Geometry and PhysicsKilling vector fields, which have their origins in Riemannian geometry, have recently garnered attention for their significance in understanding fluid flows on curved surfaces. Owing to the significance of behavior of fluid flows around the boundary and at infinity, in the context of fluid dynamics, Killing vector fields of interest should satisfy the ...
