Matsumura‐Type Estimates and Global Solutions of a Fractional Wave Equation With Nonlocal Nonlinearity

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The main results of this paper are the global existence and long time behavior of solutions of a fractional wave equation with a nonlocal nonlinearity. The techniques in this work rely on norm estimates of the solutions of εutt+ut+(−Δ)βu=0,u(0,x)=φ(x),ut(0,x)=ψ(x),$$ \varepsilon {u}_{tt}+{u}_t+{\left(-\Delta \right)}^{\beta }u=0,\kern1em u ...

A new numerical approach for solving space–time fractional Schrödinger differential equations via fractional-order Chelyshkov functions

Results in Applied Mathematics
In this paper, a numerical method for solving space–time fractional Schrödinger equations is proposed. The method employs fractional-order Chelyshkov functions and their properties to derive the remainders associated with the main problem.

Clinicopathological characteristics of patients with inoperable non‐small cell lung cancer harboring circulating NRF2 pathway mutations

The Journal of Pathology, EarlyView.
Abstract Lung cancer is the leading cause of global cancer‐related morbidity and mortality, with tobacco smoking as its strongest risk factor. Nuclear factor erythroid 2‐related factor 2 (NRF2) is a redox‐regulated transcription factor frequently dysregulated in non‐small cell lung cancer (NSCLC), leading to aggressive disease and resistance to therapy.

Nonlinear subelliptic Schrodinger equations with external magnetic field

Electronic Journal of Differential Equations, 2004
To account for an external magnetic field in a Hamiltonian of a quantum system on a manifold (modelled here by a subelliptic Dirichlet form), one replaces the the momentum operator $frac 1i d$ in the subelliptic symbol by $frac 1i d-alpha$, where ...

Parametric Excitation of a Ferrimagnetic Sphere Resonator

Advanced Quantum Technologies, EarlyView.
The hypothesis that disentanglement spontaneously occurs in quantum systems is experimentally tested using a ferromagnetic resonator. Predictions derived from the hypothesis, and from an alternative theoretical model, are compared with the measured response of the resonator to an externally applied driving.

Darboux transformation for the discrete Schrodinger equation

Electronic Journal of Differential Equations, 2019
The discrete Schrodinger equation on a half-line lattice with the Dirichlet boundary condition is considered when the potential is real valued, is summable, and has a finite first moment.

A Chiral 2D Sheet for Enhancing GLUT1 Function Through the Interplay of Architecture and Recognition

Small, EarlyView.
We show that both supramolecular architecture and glucose chirality determine biological function. Unlike self‐assembled 0D particles, we assembled with OFN to form 2D sheets. Only the (d)‐sheets with exposed d‐glucose interacted with GLUT1, increasing its expression, promoting glucose uptake, and reducing ROS.

Compact tape‐driven sample delivery system for serial femtosecond crystallography

Journal of Applied Crystallography, EarlyView.
A tape‐driven liquid sample droplet delivery system for serial femtosecond crystallography is described.We have developed a compact tape drive (CoT) with on‐demand sample delivery for time‐resolved serial femtosecond crystallography (SFX) experiments, which can deliver sample droplets and/or initiate reactions with a drop‐on‐drop strategy.

Molecular structure and nickel‐binding capacity of Proteus mirabilis UreE

Acta Crystallographica Section D, EarlyView.
This study presents a 2.0 Å resolution crystal structure and determined the nickel‐binding capacity of the P. mirabilis nickel chaperone UreE. UreE is essential for the delivery of nickel to the metalloenzyme urease, which is key for the ability of P. mirabilis to cause urinary‐tract infections.UreE is a nickel chaperone that is required for the safe ...

Molecular basis for a pore block of Tentonin 3 expressed in HEK293 cells by a conopeptide, NMB‐1

British Journal of Pharmacology, EarlyView.
Background and Purpose Tentonin 3 (TTN3/TMEM150C) is a mechanosensitive ion channel that plays critical roles in mechanotransduction processes. TTN3 forms a tetramer with a predicted rectangular shape and a central pore. A conotoxin ρ‐TIA and its synthetic analog, noxious mechanosensation blocker 1 (NMB‐1), were initially developed to inhibit slowly ...
