Nonexistence of D(4)-quintuples [PDF]

Journal of Number Theory, 2019
In this paper we prove a conjecture that $D(4)$-quintuple does not exist using both classical and new methods. Also, we give a new version of the Rickert's theorem that can be applied on some $D(4)$-quadruples.

Nonexistence of Positive Solutions for Quasilinear Equations with Decaying Potentials

Mathematics, 2020
In this paper, we consider a quasilinear Schrödinger equation, which arises from the study of the superfluid film equation in plasma physics. Our main goal is to find the growth condition for nonlinear term and decaying condition for the potential ...

Hip Morphology–Based Osteoarthritis Risk Prediction Models: Development and External Validation Using Individual Participant Data From the World COACH Consortium

Arthritis Care &Research, EarlyView.
Objective This study aims to develop hip morphology‐based radiographic hip osteoarthritis (RHOA) risk prediction models and investigates the added predictive value of hip morphology measurements and the generalizability to different populations. Methods We combined data from nine prospective cohort studies participating in the Worldwide Collaboration ...

Nonexistence results for some nonlinear elliptic and parabolic inequalities with functional parameters

Electronic Journal of Qualitative Theory of Differential Equations, 2015
We obtain results on nonexistence of nontrivial nonnegative solutions for some elliptic and parabolic inequalities with functional parameters involving the $p(x)$-Laplacian operator. The proof is based on the test function method.

Physician Referral Patterns to Physical Therapists for Managing Knee Osteoarthritis: A Retrospective Analysis of Electronic Health Records From an Integrated Health System

Arthritis Care &Research, EarlyView.
Objective This study aims to describe the frequency and timing of physician referrals to physical therapists (PTs) and other treatments prescribed over 12 months in patients with recent onset of knee osteoarthritis (KOA). The study also aims to identify determinants of early PT referrals.

Nonexistence of invariant measures [PDF]

Proceedings of the American Mathematical Society, 1983
Let G G be a group acting on a set X X . Suppose that for some positive integer r r , G G contains a free group F F of rank > r > r and the intersection of any stabilizer with F F has rank ⩽

Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Blow-up of solutions to fractional differential inequalities involving ψ-Caputo fractional derivatives of different orders

AIMS Mathematics, 2022
We consider a fractional differential inequality involving $ \psi $-Caputo fractional derivatives of different orders, with a polynomial nonlinearity and a singular potential term.

Mutual Exclusion Analysis Shows that DUSP9 Negatively Regulates PD‐L1 Expression and Acts as a Target to Enhance Anti‐PD‐1 Efficacy

Advanced Science, EarlyView.
A mutually exclusive screening system is established to identify negative regulators of highly plastic genes. Dual specificity phosphatase (DUSP9) is a novel negative regulatory molecule of PD‐L1 by dephosphorylating STAT3, and acts as a target molecule in combination with PD‐1 antibody for tumor immunotherapy and a new clinical biomarker for ...

Single‐Cell Profiling Across Immune Tissues and Organs Reveals Immunosenescence Signatures in Male Rhesus Monkeys

Advanced Science, EarlyView.
Single‐cell profiling across bone marrow, spleen, mesenteric lymph, and blood in rhesus monkeys reveals organ Immunosenescence. GZMB rises with age, particularly in cytotoxic and terminally exhausted CD8+ T cells, and BHLHE40 emerges as a key transcription factor enriched across multiple CD8+ subsets, regulating pro‐inflammatory and exhaustion‐related ...
