- ALICE (A Large Ion Collider Experiment) is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model. It is designed to address the physics of strongly interacting matter and the quark-gluon plasma at extreme values of energy density and temperature in nucleus-nucleus collisions. Besides running with Pb ions, the physics programme includes collisions with lighter ions, lower energy running and dedicated proton-nucleus runs. ALICE will also take data with proton beams at the top LHC energy to collect reference data for the heavy-ion programme and to address several QCD topics for which ALICE is complementary to the other LHC detectors. The ALICE detector has been built by a collaboration including currently over 1000 physicists and engineers from 105 Institutes in 30 countries, Its overall dimensions are 16 x 16 x 26 m(3) with a total weight of approximately 10 000 t. The experiment consists of 18 different detector systems each with its own specific technology choice and design constraints, driven both by the physics requirements and the experimental conditions expected at LHC. The most stringent design constraint is to cope with the extreme particle multiplicity anticipated in central Pb-Pb collisions. The different subsystems were optimized to provide high-momentum resolution as well as excellent Particle Identification (PID) over a broad range in momentum, up to the highest multiplicities predicted for LHC. This will allow for comprehensive studies of hadrons, electrons, muons, and photons produced in the collision of heavy nuclei. Most detector systems are scheduled to be installed and ready for data taking by mid-2008 when the LHC is scheduled to start operation, with the exception of parts of the Photon Spectrometer (PHOS), Transition Radiation Detector (TRD) and Electro Magnetic Calorimeter (EMCal). These detectors will be completed for the high-luminosity ion run expected in 2010. This paper describes in detail the detector components as installed for the first data taking in the summer of 2008.

- There are large between- and within-country variations in COVID-19 death rates. Some very low death rate settings such as Eastern Asia, Central Europe, the Balkans and Africa have a common feature of eating large quantities of fermented foods whose intake is associated with the activation of the Nrf2 (Nuclear factor (erythroid-derived 2)-like 2) anti-oxidant transcription factor. There are many Nrf2-interacting nutrients (berberine, curcumin, epigallocatechin gallate, genistein, quercetin, resveratrol, sulforaphane) that all act similarly to reduce insulin resistance, endothelial damage, lung injury and cytokine storm. They also act on the same mechanisms (mTOR: Mammalian target of rapamycin, PPARγ:Peroxisome proliferator-activated receptor, NFκB: Nuclear factor kappa B, ERK: Extracellular signal-regulated kinases and eIF2α:Elongation initiation factor 2α). They may as a result be important in mitigating the severity of COVID-19, acting through the endoplasmic reticulum stress or ACE-Angiotensin-II-AT1R axis (AT1R) pathway. Many Nrf2-interacting nutrients are also interacting with TRPA1 and/or TRPV1. Interestingly, geographical areas with very low COVID-19 mortality are those with the lowest prevalence of obesity (Sub-Saharan Africa and Asia). It is tempting to propose that Nrf2-interacting foods and nutrients can re-balance insulin resistance and have a significant effect on COVID-19 severity. It is therefore possible that the intake of these foods may restore an optimal natural balance for the Nrf2 pathway and may be of interest in the mitigation of COVID-19 severity.

- Aim: To investigate whether there is any pharmacokinetic rationale for the common practice of administering vincristine to adolescents at relatively lower doses than those to younger children. Methods: A total of 98 children, aged 1.3-17.3 y, with acute lymphoblastic leukaemia (ALL) were studied on day 1 of induction therapy. Plasma samples were drawn before and 10, 30, 360 and 1380 min after injection of vincristine 2.0 mg/m2 (maximum dose 2.0 mg) and analysed by high-performance liquid chromatography. Results: The median value (and range) for distribution half-life was 6.4 min (0.8-11.8), elimination half-life 1014 min (258-2570), volume of distribution 445 L/m 2 (137-1241) and total body clearance 362 ml/min/m2 (134-2553). No correlation was found between age and any of these pharmacokinetic parameters. The area under the concentration time curve (AUC) was significantly correlated to age (p = 0.002, ?-0.31), as expected from the dosage of vincristine. The lower AUC in children with a body surface area > 1 m2, which is reached at 8-9 y of age, indicates that they received a less intense treatment because of the capping of the vincristine dose at 2.0 mg. Conclusions: Vincristine pharmacokinetics were not age dependent in this paediatric population. Thus, we found no pharmacokinetic rationale for dose reduction in adolescents. The common practice of limiting the vincristine dose to 2.0 mg should be carefully reconsidered.

Message from the AeSIR 2021 Chairs

Konferensbidrag (refereegranskat)abstract
- It is our pleasure to welcome you to the first edition of the International Workshop on Automated Support to Improve code Readability (AeSIR) which is being virtually held and co-located with the 36th IEEE/ACM International Conference on Automated Software Engineering (ASE 2021). Reading and understanding code is essential to implement new features in an existing system, refactor, debug, write tests, and perform code reviews. Developers spend large amounts of time reading code and making the code easier to read and understand is an important goal with potential practical impact. In this context, automatically measuring and improving legibility, readability, and understandability is of primary importance to help developers addressing program comprehension issues. The Workshop on Automated Support to Improve code Readability (AeSIR) aims at providing a forum for researchers and practitioners to discuss both new approaches and emerging results related to such aspects. In this first edition of AeSIR, we have 4 accepted papers which address novel tools and approaches for automatically measuring and improving code legibility, readability, and understandability. As organizers, we would like to thank the authors of all the submitted papers, the program committee members, the ASE workshop chairs and the conference organizers, who have all contributed to the success of this workshop!
