We present a summary of the commissioning and performance of the vacuum system of a 500-MeV booster synchrotron recently built at LNLS as part of a new injector for the LNLS light source. The main vacuum parameters of the synchrotron are pressure below 5×10-7Pa (lifetime of 1-2 hours), no in-situ baking, no cooling system, and a short recovery time after ventilation. All parts of the system are ma

This concert featured the world premiere of new music for serpent from the composers Orlando Bass, Henrik Denerin, Athena Corcoran-Tadd, and Jesse Ronneau (the latter also with live electronics). The concert opened with a performance of a 17th-century work from Girolamo Frescobaldi with Orlando Bass on harpsichord. There was also a visual presentation, illustrating the history of the serpent and b

Studio recordings of new music for serpent from the composers Orlando Bass, Henrik Denerin, Athena Corcoran-Tadd, and Jesse Ronneau, recorded at the Inter Arts Center (Malmö) on 8-10 February 2025.

The aim of the RAID project (Robot for Assisting the Integration of the Disabled) is to develop and demonstrate a prototype robotic workstation for use by disabled people. The RAID project is part of the European Community TIDE program (Technology for the socio-economic Integration of disabled and Elderly people). The robotized system is intended primarily for vocational use in an office environ

We consider the elliptic-elliptic, focussing Davey-Stewartson equations, which have an explicit bright line soliton solution. The existence of a family of periodic solitons, which have the profile of the line soliton in the longitudinal spatial direction and are periodic in the transverse spatial direction, is established using dynamical systems arguments. We also show that the line soliton is lin

The Grodsky packet storage model describes many features of insulin release, but at present more or less arbitrary simplifications are necessary. The consequences of various simplifications are discussed, especially with regard to identification of parameters thought to be of importance for glucose tolerance. In particular, the insulin release dynamics of the ordinary intravenous glucose tolerance

We consider the problem of identifying structural influences of external inputs on steady-state outputs in a biological network model. We speak of a structural influence if, upon a perturbation due to a constant input, the ensuing variation of the steady-state output value has the same sign as the input (positive influence), the opposite sign (negative influence), or is zero (perfect adaptation),

Background: Celiac disease (CD) is an autoimmune disease leading to gastrointestinal symptoms and mineral deficiencies. The pathogenetic mechanisms, besides the clear HLA association, are elusive. Among environmental factors infections have been proposed. Covid-19 infection results in a systemic inflammatory response that often also involves the gastrointestinal tract. The aim of the present study

Dark matter’s presence can be inferred from gravitational interactions and astrophysical observations, but its nature is still unknown. If dark matter is a particle, then we hope to complement these observations from space and understand its nature and interactions by producing it in controlled laboratory conditions. The Large Hadron Collider (LHC), hosted at the CERN laboratory in Switzerland, pr
