Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma
Molecular Oncology, EarlyView.The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Theory of neutrino detection: flavor oscillations and weak values
European Physical Journal C: Particles and Fields, 2021 We revisit the theory of neutrino oscillations and describe it through the formalism of weak measurements with postselection. It is well understood that due to the large momentum uncertainty in detection, there is no collapse of the neutrino wavefunction

Optimal Output Regulation for Square, Over-Actuated and Under-Actuated Linear Systems
, 2019 This paper considers two different problems in trajectory tracking control for linear systems. First, if the control is not unique which is most input energy efficient. Second, if exact tracking is infeasible which control performs most accurately. These

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics
FEBS Open Bio, EarlyView.Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Numerical Treatment Of The Bounded-Control LQR Problem By Updating The Final Phase Value
IEEE Latin America Transactions, 2016 A novel approach has been developed for approximately solving the constrained LQR problem, based on updating the final state and costate of an unrestricted related regular problem, and the switching times (when the control meets the constraints). The main result is the expression of a suboptimal control in feedback form by using some corresponding ...

The Energy of a Dynamical Wave-Emitting System in General Relativity [PDF]
, 2003 The problem of energy and its localization in general relativity is critically re-examined. The Tolman energy integral for the Eddington spinning rod is analyzed in detail and evaluated apart from a single term.

FEBS Open Bio, EarlyView.We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.
