The measured properties of the recently discovered Higgs boson are in good agreement with predictions from Standard Model. However, small deviations couplings may manifest themselves once currently large uncertainties will be improved as part LHC program and at a future factory. We review typical new physics scenarios that lead to observable modifications interactions. They can divided into two broad categories: mixing effects portal models or extended sectors, vertex loop matter gauge...
VBFNLO is a flexible parton level Monte Carlo program for the simulation of vector boson fusion (VBF), QCD-induced single and double production plus two jets, triple (plus jet) in hadronic collisions at next-to-leading order (NLO) strong coupling constant, as well Higgs jet via gluon one-loop level. For new version -- Version 3.0 several major enhancements have been included. An interface according to Binoth Les Houches Accord (BLHA) has added all VBF di/tri-boson processes including fully...
BNT162b2 by Pfizer-BioNTech and mRNA-1273 Moderna are the most commonly used vaccines to prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections. Head-to-head comparison of efficacy these in immunocompromised patients is lacking.Parallel, 2-arm (allocation 1:1), open-label, noninferiority randomized clinical trial nested into Swiss HIV Cohort Study Transplant Study. People living with human immunodeficiency virus (PLWH) or solid organ transplant recipients (SOTR; ie,...
We surveyed neuro-oncologists regarding patients treated with temozolomide for at least 12 cycles or months. Patients receiving first-line a median 13 had progression-free survival (PFS) of 14 recurrent disease PFS 15.5 A small percentage experienced grade III to IV toxicity. These results suggest that long-term treatment is feasible and well tolerated.
Abstract Objective. Monolithic active pixel sensors are used for charged particle tracking in many applications, from medical physics to astrophysics. The Bergen pCT collaboration designed a sampling calorimeter proton computed tomography, based entirely on the ALICE PIxel DEtector (ALPIDE). same telescope can be in-situ range verification therapy. An accurate charge diffusion model is required convert deposited energy Monte Carlo simulations cluster of pixels, and estimate energy, given an...
The computation of the NLO-QCD corrections to cross sections for W \gamma production in hadronic collisions is presented. We consider case real photons final state, but include full leptonic decays W. Numerical results LHC and Tevatron are obtained through a parton level Monte Carlo based on structure VBFNLO program, allowing an easy implementation general cuts distributions. show dependence scale variations integrated provide evidence fact that NLO QCD strongly modify LO predictions...
We present a calculation of the $\mathcal{O}({\ensuremath{\alpha}}_{s})$ QCD corrections to production $Z$ boson in association with two photons and triple-photon at hadron colliders. All final-state are taken as real. For boson, we consider decays both into charged leptons neutrinos including all off-shell effects. Numerical results obtained via Monte Carlo program based on structure VBFNLO package. This allows us implement general cuts distributions particles. find that next-to-leading...
Objective.Proton therapy is highly sensitive to range uncertainties due the nature of dose deposition charged particles. To ensure treatment quality, verification methods can be used verify that individual spots in a pencil beam scanning fraction match plan. This study introduces novel metric for proton quality control based on spots.Approach.We employ uncertainty-aware deep neural networks predict Bragg peak depth an anthropomorphic phantom secondary particle detection silicon pixel...
2005 Background: Acute chemotherapy-associated toxicity is an important issue in PCNSL since these patients are usually of advanced age, impaired clinical condition, and often suffer from comorbidities. We present analysis prognostic factors for chemotherapy-related acute a German multicenter phase III trial (G-PCNSL-SG-1). Methods: Five-hundred twenty-six eligible (median age 63 years, median Karnofsky performance status (KPS) 70%) treated with at least one chemotherapy course were analyzed...
8008 Background: High-dose methotrexate (HDMTX) is considered the standard of care for patients with newly diagnosed primary central nervous system lymphoma (PCNSL). The role whole-brain radiotherapy (WBRT) has remained controversial. Delayed neurotoxicity limits its acceptance as a care. Methods: Immunocompetent PCNSL were randomized to chemotherapy followed by WBRT (arms A1, B1) or alone (A2, B2). After randomization, all receive 6 cycles HDMTX (4 g/m2, D1, biweekly) from 1999-2007 and...

This paper describes prototyping work for service hybrids, flexible circuits that form an integral part of the silicon strip modules to be used in CMS Phase-2 Outer Tracker. The hybrid is responsible power distribution, data serialization, and opto-electrical conversion. First prototype featuring complete functionality, have been developed, produced, characterized. In addition a first test board, which allows all aspects complex as will required during production phase, has developed. After...
