We discuss recurrently connected neural networks, investigating their global exponential stability (GES). Some sufficient conditions for a class of recurrent neural networks belonging to GES are given. Sharp convergence rate is given too.

Cytotoxin-associated gene A (CagA) is one of the most important virulence factors of Helicobacter pylori, and serves a role in H. pylori‑mediated tumorigenesis in gastric cancer. However, the underlying molecular mechanism remains to be elucidated. The present study aimed to investigate the effects of CagA on the proliferation and apoptosis of GES‑1 cells, and the underlying mechanism. A CagA e...

BACKGROUND Gastric electric stimulation (GES) at a high-frequency, low-energy setting is an option for treating refractory gastroparesis. The currently available commercial stimulator, the Enterra neurostimulator (Medtronic Inc, Minneapolis, MN), however, requires surgical implantation and is powered by a nonrechargeable battery. OBJECTIVE To develop and test a miniature wireless GES device f...

BACKGROUND/AIM Sustained attention is a vital function mediated by the right frontoparietal cortex. The Six Letter Cancellation Task (SLCT) measures sustained attention. Development of sustained attention in a yoga-based education system compared to a modern one is the theme of the present study. AIM To compare the effectiveness of the Modern Education System (MES) and the Gurukula Education ...

BACKGROUND/AIMS Gastroparesis is characterized by delayed gastric emptying without obstruction. Diabetes is frequently associated with poor glycemic control and delayed gastric emptying. Gastric emptying scintigraphy (GES) is the standard for measuring gastric emptying. Serum hemoglobin A1C (HbA1C) measures prolonged glycemic control with normal as < 7% glycated. To date, no correlation of seru...

Gastric electrical stimulation (GES) for gastroparesis has been in use for more than a decade. Multiple publications, consisting almost entirely of open label single center studies, reported a beneficial effect on symptoms, quality of life and nutritional status. Some predictors of better response to GES have been lately identified, primarily diabetic etiology and nausea and vomiting as the pre...

We perform first-principles, density-functional-theory calculations of the electronic structure for the layered bulk materials SnS and GeS which are of interest for photovoltaic applications. Band gap corrections are computed within the GW approximation to the electron self-energy. The resulting quasiparticle gaps in both SnS and GeS are in excellent agreement with the majority of existing expe...

22 Resistance to ß-lactams is constantly increasing, due to the emergence of totally new 23 enzymes, but also to the evolution of pre-existing ß-lactamases. GES-1 is a clinically24 relevant extended-spectrum -lactamase (ESBL) hydrolyzing penicillins and broad25 spectrum cephalosporins, but sparing monobactams and carbapenems. However, 26 several GES-1 variants (i.e. GES-2 and GES-5) previously ...
