We perform a detailed analysis of broad pulses in bright gamma-ray bursts (GRBs) to understand the evolution of GRB broad pulses. Using the temporal and spectral properties, we test the high-latitude emission (HLE) scenario in the decaying phase of broad pulses. [...]

Context. To date, three nuclear transients have been associated with high-energy neutrino events [...]

Non-destructive Schottky detectors are indispensable devices widely used in experiments at heavy-ion storage rings. In particular, they can be used to accurately determine the masses and lifetimes of short-lived exotic nuclear species. [...]

Silicon strip sensors developed for the ATLAS Inner Tracker Upgrade have shown a strong dependence of the breakdown voltage on varying levels of relative humidity (RH). The solution to this humidity sensitivity has so far been to store and test the sensors in a dry environment (RH < 10 %). [...]

Ecto-5’-nucleotidase (CD73) is a potential new drug target for cancer immunotherapy. Its overexpression is associated with various aggressive cancers, including triple-negative breast cancer (TNBC) and pancreatic cancer, making it a promising target for diagnostic imaging. [...]

In this thesis the electroweak production of the Z boson in association with twojets is investigated focusing on its topology via the Vector Boson Fusion (VBF)mechanism and the determination of heavy boson parton densities.The first part presents a theoretical study of the Drell–Yan and electroweak Zjj pro-duction mechanisms and their particle-level comparison, demonstrating the domi-nance of the former and motivating the definition of a VBF-enhanced phase space toisolate electroweak contributions. The impact of electroweak corrections is discussedas a motivation for introducing electroweak (heavy boson) densities [...]

TBC (Tre2/Bub2/Cdc16) domain-containing proteins constitute the widespread family of GTPase-activating proteins (GAPs). They interact with the Rab superfamily of small GTPases, stimulate GTP hydrolysis, and regulate vesicle trafficking. [...]

Aspartate transcarbamoylase (ATC) catalyzes the committed and rate-limiting step in the pyrimidine de novo biosynthesis pathway. While previously suggested to be a potential target for antimalarial, antitubercular, and antioncologic drug discovery, we hypothesized that an existing compound library of ATC inhibitors designed from one scaffold by fragment screening against Plamodium falciparum ATC (PfATC) may also contain inhibitors of Trypanosoma cruzi ATC (TcATC). [...]

Herein, we present crystal structures of proteins adopting a fold not identified among known -solenoids in current structural databases, a Knotted Solenoid. These proteins exhibit a characteristic solenoidal architecture, closely resembling -solenoid proteins. [...]
