Resonant Emittance Mixing of Flat Beams in Plasma Accelerators.

Phys Rev Lett

December 2024

Deutsches Elektronen-Synchrotron DESY, Notkestrasse 85, 22607 Hamburg, Germany.

Linear colliders rely on high-quality flat beams to achieve the desired event rate while avoiding potentially deleterious beamstrahlung effects. Here, we show that flat beams in plasma accelerators can be subject to quality degradation due to emittance mixing. This effect occurs when the beam particles' betatron oscillations in a nonlinearly coupled wakefield become resonant in the horizontal and vertical planes.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Introduction: HIV self-testing (HIVST) is an innovative strategy that has been shown to increase uptake of HIV testing compared to conventional facility-based testing. HIVST implementation with digital-based supports may help facilitate testing accessibility and linkage to care after a reactive self-test. Economic evidence around community-based implementation of HIVST is growing; however, economic evidence around digital-based HIVST approaches remains limited.

Carbon capture and storage (CCS) and CO-based geothermal energy are promising technologies for reducing CO emissions and mitigating climate change. Safe implementation of these technologies requires an understanding of how CO interacts with fluids and rocks at depth, particularly under elevated pressure and temperature. While CO-bearing aqueous solutions in geological reservoirs have been extensively studied, the chemical behavior of water-bearing supercritical CO remains largely overlooked by academics and practitioners alike.

Self-care interventions for legal and safe abortions: lessons learned from a woman-centered approach to sexual and reproductive healthcare in Uruguay.

Lancet Reg Health Am

February 2025

Department of Sexual and Reproductive Health and Research, Including the UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP), World Health Organization, Geneva, Switzerland.

Problem: In the 1990s, almost 40% of maternal deaths in Uruguay were caused by unsafe abortions.

Approach: A harm reduction model implemented in Uruguay, which addressed the risks associated with unsafe abortion practices by promoting and supporting the self-management of medical abortions by women in their homes, encouraged women's autonomy.

Local Setting: Since 2005, an accelerated decrease in maternal mortality has been recorded in Uruguay, coinciding with the implementation of two major actions: a harm reduction approach with active promotion of self-care through self-management of medical abortions; and in 2012, a change in legislation, which made abortion legal within sexual and reproductive health facilities when requested by women up to 12 weeks of pregnancy or later for specific indications.

This article attends to the emotional resonances of 'stuckedness' and (in)voluntary return as experienced by Nicaraguan migrants stranded in Spain during the COVID-19 pandemic. Feeling both figuratively and literally trapped in a context of cascading lockdowns, border closures, and travel restrictions, many viewed Spain's Assisted Voluntary Return and Reintegration (AVRR) programme as offering a choice to 'freely' depart Spain - a way to simultaneously leave their distressing circumstances behind while returning to the comfort of 'home' and family. Building on recent literature that challenges the basis for participation in such programmes as founded on free, voluntary, and individual decisions, this article contends that, for some, the act of 'choosing' to return generates a profound and unexpected emotional response.

Oligonucleotides (ONs) are an increasingly popular category of molecules in the pharmaceutical landscape, particularly attractive for the treatment of genetic and rare diseases. However, analyzing these molecules presents significant challenges, due to their highly hydrophilic nature, multiple negative charges, and the presence of closely related impurities resulting from the complex solid-phase synthesis process. Ion pairing reverse-phase liquid chromatography (IP-RPLC) is the preferred technique for ONs analysis but is not ideal for mass spectrometry (MS) coupling.

We conducted a genome-wide association study on income among individuals of European descent (N = 668,288) to investigate the relationship between socio-economic status and health disparities. We identified 162 genomic loci associated with a common genetic factor underlying various income measures, all with small effect sizes (the Income Factor). Our polygenic index captures 1-5% of income variance, with only one fourth due to direct genetic effects.

Background: Health authorities worldwide have invested in digital technologies to establish robust information exchange systems for improving the safety and efficiency of medication management. Nevertheless, inaccurate medication lists and information gaps are common, particularly during care transitions, leading to avoidable harm, inefficiencies, and increased costs. Besides fragmented health care processes, the inconsistent incorporation of patient-driven changes contributes to these problems.

HIV-prevention efforts focusing on women of child-bearing potential are needed to end the HIV epidemic in the African region. The use of antiretroviral drugs as pre-exposure prophylaxis (PrEP) is a critical HIV prevention tool. However, safety data on new antiretrovirals during pregnancy are often limited because pregnant people are excluded from drug development studies.

Nebulized aminoglycosides for ventilator-associated pneumonia: Methodological considerations and lessons from experimental studies.

J Intensive Med

January 2025

Department of Pneumology, Institut Clinic del Tórax, Hospital Clinic of Barcelona - Institut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), University of Barcelona - SGR 911- Ciber de Enfermedades Respiratorias (Ciberes), Barcelona, Spain.

Aminoglycosides are concentration-dependent antibiotics exerting a bactericidal effect when concentrations at the site of infection are equal to or greater than 5 times the minimum inhibitory concentrations (MIC). When administered intravenously, they exhibit poor lung penetration and high systemic renal and ototoxicity, imposing to restrict their administration to 5 days. Experimental studies conducted in anesthetized and mechanically ventilated sheep and pigs provide evidence that high doses of nebulized aminoglycosides induce a rapid and potent bacterial killing in the infected lung parenchyma.

Pragmatic realism: towards a reconciliation of enactivism and realism.

Phenomenol Cogn Sci

February 2024

Department of Philosophy, University of Geneva, 5 rue De-Candolle, Genève, 1211 Switzerland.

This paper addresses some apparent philosophical tensions between realism and enactivism by means of Charles Peirce's pragmatism. Enactivism's Mind-Life Continuity thesis has been taken to commit it to some form of anti-realist 'world-construction' which has been considered controversial. Accordingly, a new realist enactivism is proposed by Zahidi ( (3), 461-475, 2014), drawing on Ian Hacking's 'entity realism', which places subjects in worlds comprised of the things that they can successfully manipulate.

Modulation of microtubule dynamics by monovalent ions.

PNAS Nexus

January 2025

Department of Biochemistry, University of Geneva, 1211 Geneva, Switzerland.

The microtubule cytoskeleton is a dynamic network essential for many cellular processes, influenced by physicochemical factor, such as temperature, pH, dimer concentration, and ionic environment. In this study, we used in vitro reconstitution assays to examine the effects of four monovalent ions (Na, K, Cl, and Ac) on microtubule dynamics, uncovering distinct effects for each ion. Na was found to increase microtubule dynamicity by raising catastrophe frequency, polymerization and depolymerization speeds, and ultimately reducing microtubule lifetime by 80%.
