A Dirac System with Transmission Condition and Eigenparameter in Boundary Condition
This paper deals with a Dirac system with transmission condition and eigenparameter in boundary condition. We give an operator-theoretic formulation of the problem then investigate the existence of the solution.

Tooth mode has been proven to be adaptable for the diagnosis of periodontal disease. However, in previous studies of tooth mode computation, model settings, including boundary condition and model structure integrity, were quite different.

This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

First-Order Boundary Value Problem with Nonlinear Boundary Condition on Time Scales
This work is concerned with the following first-order dynamic equation on time scale , xΔ(t)+p(t)x(σ(t))=f(t,x(t)), t∈[0,T]𝕋 with the nonlinear boundary condition x(0)=g(x(σ(T))).

A convective-like energy-stable open boundary condition for simulations of incompressible flows [PDF]
We present a new energy-stable open boundary condition, and an associated numerical algorithm, for simulating incompressible flows with outflow/open boundaries.

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

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

DeWitt Boundary Condition in One-Loop Quantum Cosmology
DeWitt’s suggestion that the wave function of the universe should vanish at the classical Big Bang singularity is considered here within the framework of one-loop quantum cosmology.

Existence of a weak solution to a fluid-elastic structure interaction problem with the Navier slip boundary condition [PDF]
We study a nonlinear, moving boundary fluid-structure interaction problem between an incompressible, viscous Newtonian fluid, modeled by the 2D Navier-Stokes equations, and an elastic structure modeled by the shell or plate equations.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...
