Search for Higgs boson decays into a pair of pseudoscalar particles in the bbμμ final state with the ATLAS detector in pp collisions at s =13 TeV

This paper presents a search for decays of the Higgs boson with a mass of 125 GeV into a pair of new pseudoscalar particles, H→aa, where one a-boson decays into a b-quark pair and the other into a muon pair. The search uses 139 fb-1 of proton-proton collision data at a center-of-mass energy of s=13 TeV recorded between 2015 and 2018 by the ATLAS experiment at the LHC. A narrow dimuon resonance is

Search for heavy particles in the b -tagged dijet mass distribution with additional b -tagged jets in proton-proton collisions at s =13 TeV with the ATLAS experiment

A search optimized for new heavy particles decaying to two b-quarks and produced in association with additional b-quarks is reported. The sensitivity is improved by b-tagging at least one lower-pT jet in addition to the two highest-pT jets. The data used in this search correspond to an integrated luminosity of 103 fb-1 collected with a dedicated trijet trigger during the 2017 and 2018 s=13 TeV pro

Detection of the tidal deformation of WASP-103b at 3 σ with CHEOPS

Context. Ultra-short period planets undergo strong tidal interactions with their host star which lead to planet deformation and orbital tidal decay. Aims. WASP-103b is the exoplanet with the highest expected deformation signature in its transit light curve and one of the shortest expected spiral-in times. Measuring the tidal deformation of the planet would allow us to estimate the second degree fl

Search for Lepton-Flavor Violation in Z -Boson Decays with τ Leptons with the ATLAS Detector

A search for lepton-flavor-violating Z→eτ and Z→μτ decays with pp collision data recorded by the ATLAS detector at the LHC is presented. This analysis uses 139 fb-1 of Run 2 pp collisions at s=13 TeV and is combined with the results of a similar ATLAS search in the final state in which the τ lepton decays hadronically, using the same data set as well as Run 1 data. The addition of leptonically dec

Soft-Dielectron Excess in Proton-Proton Collisions at s =13 TeV

A measurement of dielectron production in proton-proton (pp) collisions at s=13 TeV, recorded with the ALICE detector at the CERN LHC, is presented in this Letter. The data set was recorded with a reduced magnetic solenoid field. This enables the investigation of a kinematic domain at low dielectron (ee) invariant mass mee and pair transverse momentum pT,ee that was previously inaccessible at the

This study analyzes some of the factors that facilitate and complicate advanced legal teaching in human rights as a subject of international law. The main objective is to offer a reflection on the challenges faced by the teacher in this field and which arise as a result of the expansion, diversification, and confrontation of the subject taught. According to the argument developed, a classical or t

An increasing number of litigations before the International Court of Justice (ICJ) concerns situations involving serious crimes (genocide, crimes against humanity and war crimes). However, to date, several of these litigations have failed to deliver justice in the form of reparations to the victims of these crimes. Two recurrent legal obstacles impede effective results: the limits imposed on this

Regenerating islet-derived protein 3α : A promising therapy for diabetes. Preliminary data in rodents and in humans

The aim of our study was to test the hypothesis that administration of Regenerating islet-derived protein 3α (Reg3α), a protein described as having protective effects against oxidative stress and anti-inflammatory activity, could participate in the control of glucose homeostasis and potentially be a new target of interest in the treatment of type 2 diabetes. To that end the recombinant human Reg3α

Neuronal Dysfunction Is Linked to the Famine-Associated Risk of Proliferative Retinopathy in Patients With Type 2 Diabetes

Persons with type 2 diabetes born in the regions of famine exposures have disproportionally elevated risk of vision-threatening proliferative diabetic retinopathy (PDR) in adulthood. However, the underlying mechanisms are not known. In the present study, we aimed to investigate the plausible molecular factors underlying progression to PDR. To study the association of genetic variants with PDR unde

After the Caliphate: Changing Mobilization in the Swedish Salafi-Jihadist Environment following the Fall of ISIS

After the fall of the Islamic State’s self-declared Caliphate in Syria and Iraq, understanding how the Salafi-jihadist environments in the West mobilize in new ways has become urgent. This study is based on unique hard-to-reach data from qualitative interviews with returned Swedish ISIS fighters, previous members of the Swedish Salafi-jihadist environment, friends and acquaintances of persons enga

Space–Time Surveillance of COVID-19 Seasonal Clusters : A Case of Sweden

While COVID-19 is a global pandemic, different countries have experienced different morbidity and mortality patterns. We employ retrospective and prospective space–time permutation analysis on COVID-19 positive records across different municipalities in Sweden from March 2020 to February 2021, using data provided by the Swedish Public Health Agency. To the best of our knowledge, this is the first

Early neuro-electric indication of lexical match in English spoken-word recognition

We investigated early electrophysiological responses to spoken English words embedded in neutral sentence frames, using a lexical decision paradigm. As words unfold in time, similar-sounding lexical items compete for recognition within 200 milliseconds after word onset. A small number of studies have previously investigated event-related potentials in this time window in English and French, with r

Building urban resilience through sustainability-oriented small- and medium-sized enterprises

The unfolding COVID-19 pandemic, and the unprecedented social and economic costs it has inflicted, provide an important opportunity to scrutinize the interplay between the resilience of small and medium-sized enterprises (SMEs) and the resilience of the communities they are embedded in. In this article, we articulate the specific ways that SMEs play a crucial, and underappreciated role in building

Assessment and Intervention for Tool-Use in Learning Powered Mobility Intervention: A Focus on Tyro Learners

Young infants, children, and persons of any age who have cognitive limitations can be thought of as tyro learners, who are beginners in learning. For tyro learners, the self-produced mobility afforded by a powered mobility device offers opportunities, to explore tool-use learning and interact with the surrounding environment, thereby potentially enhancing development and learning, providing a foun

GDP, not the Bond Yield, should Remain the Anchor of the EU Fiscal Framework

Declining bond yields and rising public debts have caused many economists to suggest raising the debt ceiling in the EU’s Stability and Growth Pact. Implicitly, they argue for replacing GDP as the anchor with the bond yield. We discuss the risks of such a shift. While such a change would provide shortterm relief to highly indebted EU member states, it is based on the expectation that bond yields wDeclining bond yields and rising public debts have caused many economists to suggest raising the debt ceiling in the EU’s Stability and Growth Pact.

Academia and society in collaborative knowledge production towards urban sustainability : several schemes—three common crossroads

Arrangements for collaboration in knowledge production across academia, government, non-governmental organisations, and corporations have several names, such as citizen-science, community-based participatory research, engaged research and hybrid forums. The multiplicity of schemes does not lie only in the high number of names for various versions of collaborative knowledge production. Different sc

3D X-ray microscopy with a CsPbBr3 nanowire scintillator

X-ray microscopy is an essential imaging method in many scientific fields, which can be extended to three-dimensional (3D) using tomography. Recently, metal halide perovskite (MHP) nanomaterials have become a promising candidate for X-ray scintillators, due to their high light yield, high spatial resolution, and easy fabrication. Tomography requires many projections and therefore scintillators wit
