The mass of the Higgs boson is measured in the H→γγ decay channel, exploiting the high resolution of the invariant mass of photon pairs reconstructed from the decays of Higgs bosons produced in proton–proton collisions at a centre-of-mass energy s=13 TeV. The dataset was collected between 2015 and 2018 by the ATLAS detector at the Large Hadron Collider, and corresponds to an integrated luminosity
What constraints and conditions are conducive to the innovation of more advanced watercraft technology? This paper explores this question by modeling ancient voyages in the Channel Island region of southern California. The Chumash and Tongva cultures of this region invented an advanced form of boat, the sewn plank canoe, around 500 CE. This new technology led to a rapid increase in maritime travel
Background: In patients undergoing resection for pancreatic cancer, adjuvant modified fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) improves overall survival compared with alternative chemotherapy regimens. We aimed to compare the efficacy and safety of neoadjuvant FOLFIRINOX with the standard strategy of upfront surgery in patients with resectable pancreatic ductal adenocarci
This letter reports the observation of W(ℓν)γγ production in proton-proton collisions. This measurement uses the full Run 2 sample of events recorded at a center-of-mass energy of s=13 TeV by the ATLAS detector at the LHC, corresponding to an integrated luminosity of 140 fb−1. Events with a leptonically-decaying W boson and at least two photons are considered. The background-only hypothesis is rej
The purpose of this paper is to analyse the evolution of Qatar and the UAE’s foreign aid and compare them in the same context: the Syrian early recovery. Analysing data on projects financed as well as the geographical, sectoral, and channel allocation of aid, the article highlights crucial aspects of these two Gulf donors’ behaviours. To examine their modus operandi, this research focuses on the S
This article compares two Islamic organisations, a non-governmental and a national one, in their methods of collecting and distributing zakat, and analyses how they addressed the COVID-19 crisis with these funds in the period 2020–2021. The study examines Islamic Relief as a Muslim non-governmental organisation involved in humanitarian response, and the National Board of the Zakat Republic of Indo
Context. TOI-732 is an M dwarf hosting two transiting planets that are located on the two opposite sides of the radius valley. Inferring a reliable demographics for this type of systems is key to understanding their formation and evolution mechanisms. Aims. By doubling the number of available space-based observations and increasing the number of radial velocity (RV) measurements, we aim at refinin
Background: The COVID-19 pandemic adversely affected health care systems. Patients in need of transcatheter aortic valve replacement (TAVR) are especially susceptible to treatment delays. Objectives: This study sought to evaluate the impact of the COVID-19 pandemic on global TAVR activity. Methods: This international registry reported monthly TAVR case volume in participating institutions prior to
Purpose: This article reports on jaw articulation, in connection with the segmental articulations of tongue tip and lips. The jaw is considered a syllable articulator as it opens and closes for each syllable, and the amount of jaw opening is related to syllable strength, given the same phonemic vowel. Here, we investigate the syllabic and the segmental articulations relationships to the acoustic s
Blomväxterna, eller angiospermerna som de kallas i vetenskapliga sammanhang, omfattar idag över 295 000 olika arter. Men denna siffra ändras ständigt eftersom det beskrivs ungefär 2 000 nya arter varje år. För att kunna ha överblick över en så stor mängd behöver den organiseras på ett vettigt sätt. Det har botanister försökt med alltsedan Linnés tid.
Charles Darwin (1809–1882) är främst känd för sin evolutionsteori– om arters utveckling genom naturligt urval. Hans övriga arbetenär mindre kända. Mycket handlade om växter – om mekanismer för pollinering, blombiologi, rörelser och förmågan att ta upp näring från andra organismer – sådant som intresserat honom sedan studietiden i Cambridge. Med tiden kom han att publicera ett flertal böcker och en
PurposeThis study aimed to elucidate whether gadolinium contrast in clinically relevant doses can be used with photon-counting computed tomography (PCCT) as an alternative contrast agent in clinical applications.Material/methodsA CTDI phantom with 3D printed rods filled with different concentrations of gadolinium and iodine contrast was scanned in a PCCT and an energy-integrated computed tomograph
Materials with heterogeneous microstructures architected across several scales are becoming increasingly popular in structural applications due to unique strength–ductility balance. One of the most popular 3D-architected structure designs is harmonic structure (HS) where soft coarse-grain (CG) islands are embedded in a hard continuous 3D skeleton of ultrafine grains (UFGs). In this work, a series
Since the Industrial Revolution, human activities have elevated atmospheric CO2 concentrations. The consequences of this include rising temperatures, shifts in precipitation patterns, and increased intensity and frequency of extreme weather events, such as heat waves and droughts. Elevated temperatures can accelerate microbial activity in soil, potentially resulting in an increased rate of soil
