XENON Dark Matter Project searches for the dark matter candidate, the Weakly Interacting Massive Particle (WIMPs). All XENON experiments use a time projection chamber (TPC) to detect nuclear recoils resulting from WIMP-nuclei scattering. Photomultiplier tubes (PMTs) read out the signal from the scintillation and ionization of the xenon triggered by the nuclear recoils. This paper details PMT ga...

The KM3NeT Collaboration has developed a multi-PMT optical so lution for construction of the two deep-sea ARCA and ORCA telescopes. This approach several advantages compared to single-PMT modules which have been traditionally used in neutrino telescopes, including larger photocathode area is equivalent three 10-inch photomultipliers. In addition, allows high resolution, good positioning timing ...

BACKGROUND The effects produced by transcranial direct current stimulation (tDCS) applied to the motor system have been widely studied in the past, chiefly focused on primary motor cortex (M1) excitability. However, the effects on functional tasks are less well documented. OBJECTIVE This study aims to evaluate the effect of tDCS-M1 on goal-oriented actions (i.e., arm-reaching movements; ARM),...

A subset of patients with recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN) benefit from pembrolizumab and nivolumab, but the majority of patients do not probably due to lack of activated cytotoxic CD8+ T-cells in their tumor tissues. Herein, we aim to investigate whether specific protein methyltransferases (PMTs) and demethylases (PDMTs) could play any roles in the CD8+...

گیاهان عالی حاوی گستره¬ی وسیعی از مواد شیمیایی مفید برای مصارف دارویی بوده که می¬توان آنها را پایانه های متابولیسم در سلول های گیاهی دانست. بذرالبنج مصری گیاه دارویی مهمی به شمار می¬رود و دو ماده هیوسیامین و اسکوپولامین که دو ترکیب دارویی ارزشمند بوده از محصولات نهایی مسیر بیوسنتزی آلکالوئیدهای تروپانی در این گونه است. اسکوپولامین ارزش تجاری بالاتری نسبت به پیش ساز آن یعنی هیوسیامین و سایر ترکی...

Background: The prevalence of pregnant women with a risk Chronic Energy Deficiency (CED) is quite high (24.2%). CED in requires additional feeding interventions (PMT). Brownies enriched taro flour–mung bean sprouts and purple sweet potato (TALAHIBU) were chosen as it an energy-dense product expected to have preferred organoleptic value energy PMT.
 Objectives: To determine the phenolic ant...

Phosphaturic mesenchymal tumors (PMTs) are very rare tumors which are frequently associated with Tumor Induced Osteomalacia (TIO), a paraneoplastic syndrome that manifests as renal phosphate wasting. The tumor cells produce a peptide hormone-like substance known as fibroblast growth factor 23 (FGF23), a physiologic regulator of phosphate levels. FGF23 decreases proximal tubule reabsorption of p...

The cubic-kilometre neutrino telescope, which consists of large-scale 3D-arrays photomultiplier tubes (PMTs) currently under construction on the Mediterranean seabed, relies accurate calibration procedures in order to answer its science goals. These proceedings present gain method used KM3NeT, is based highly compressed PMT hit information. In particular, it shown that gains can be tuned within...
