In this manuscript we propose a structural condition on nonseparable Hamiltonians, which term displacement monotonicity condition, to study second-order mean field games master equations. A rate of dissipation bilinear form is brought bear global (in time) well-posedness theory, based priori uniform Lipschitz estimates the solution in measure variable. Displacement being sometimes dichotomy with widely used Lasry–Lions novelties work persist even when restricted separable Hamiltonians.

Objective Turnover of cartilage endplate extracellular matrix (ECM) may play an important role in disc degeneration and low back pain (LBP). However, the expression pattern pro‐inflammatory factors, metalloproteinases (MMP), tissue inhibitors (TIMP) endplates (CEP) intervertebral discs (IVD) is not understood. We aimed to examine transcriptional levels MMP, TIMP, interleukins (IL), correlations between them. Methods Thirty degenerated samples from patients with LBP who underwent lumbar...

Speech processing involves a complex interplay between sensory and motor systems in the brain, essential for early language development. Recent studies have extended this sensory-motor interaction to visual word processing, emphasizing connection reading handwriting during literacy acquisition. Here we show how language-motor areas encode motoric features of stimuli auditory perception, using functional magnetic resonance imaging (fMRI) combined with representational similarity analysis....

.This paper is a continuation of our accompanying [M. Talbi, N. Touzi, and J. Zhang, Dynamic Programming Equation for the Mean Field Optimal Stopping Problem, https://arxiv.org/abs/2103.05736, 2021], where we characterized mean field optimal stopping problem by an obstacle equation on Wasserstein space probability measures, provided that value function smooth. Our purpose here to establish this characterization under weaker regularity requirements. We shall define notion viscosity solutions...

Abstract Background The application of artificial intelligence patient-controlled analgesia (AI-PCA) facilitates the remote monitoring management, implementation mobile ward rounds, and automatic recording all types key data in clinical setting. However, it cannot quantify quality postoperative management. This study aimed to establish an index (analgesia (AQI)) re-monitor re-evaluate system, equipment, medical staff degree patient matching pain management through machine learning. Methods...

Open radical inguinal lymphadenectomy is reported to have morbidity as high 50%. We describe our endoscopic that aims at decreasing the of procedure without compromising oncologic outcomes.Eleven groin dissections were undertaken in seven male patients. The was performed via three ports. first one a 10-mm incision 3 mm distal apex femoral triangle. Two additional trocars (10 and 5 mm) positioned 6 cm medially laterally triangle, respectively. Taking great saphenous vein landmark, superficial...

Diaphyseal defects in long bones of extremities following segmental resection are very common the clinic, and reconstruction remains a great challenge. Although there many treatments for diaphyseal at present, with an intercalary endoprosthesis may be optimal method. We demonstrate surgical technique humeral shaft defect tumor resection, achieve good clinical outcome. conclude that comparison other methods, is simple, effective, allows earlier weight bearing more rapid restoration function.

This report presents a rare case of 41-year-old woman with decreased sensation and weakness grip her left hand. On examination she had well-defined mass on the ulnar-volar aspect wrist. Magnetic resonance imaging showed focal nodular in Guyon’s canal. Examination that mass, 2.1 × 1.1 1.0 cm size, originated proximal portion canal was loosely associated tendon sheath flexor carpi ulnaris. The removed released. Histological confirmed diagnosis fibroma sheath. Postoperatively, fully restored...
