Underlying event properties in pp collisions at √s = 13 TeV

This article reports measurements characterizing the Underlying Event (UE) associated with hard scatterings at midrapidity (|η| < 0.8) in pp collisions at s = 13 TeV. The hard scatterings are identified by the leading particle, the charged particle with the highest transverse momentum (pTleading) in the event. Charged-particle number-densities and summed transverse-momentum densities are measured

Colonial and indigenous institutions in the fiscal development of French indochina

Official revenue collections in French Indochina were low compared with most other colonies in East and Southeast Asia. This fact stands in contrast to a large body of literature that claims French tax demands were a crushing burden on many indigenous people. French Indochina is often put forward as an example of one of the most extractive colonial states in Asia. This chapter reconciles these see

Sepsis Is Underreported in Swedish Intensive Care Units: A Retrospective Observational Multicentre Study

BackgroundSepsis is a common indication for admission to the intensive care unit (ICU). Since definitions vary across studies, comparisons of prevalence and outcomes have been challenging. We aimed to compare sepsis according to ICU discharge codes with sepsis according to Sepsis‐3 criteria and to investigate the epidemiology of sepsis in the ICU. We hypothesized that sepsis using discharge codes

The chemical compositions of accreted and in situ galactic globular clusters according to SDSS/APOGEE

Studies of the kinematics and chemical compositions of Galactic globular clusters (GCs) enable the reconstruction of the history of star formation, chemical evolution, and mass assembly of the Galaxy. Using the latest data release (DR16) of the SDSS/APOGEE survey, we identify 3090 stars associated with 46 GCs. Using a previously defined kinematic association, we break the sample down into eight se

Complications after medullary thyroid carcinoma surgery : multicentre study of the SQRTPA and EUROCRINE® databases

Background: Surgery is the curative therapy for patients with medullary thyroid carcinoma (MTC). In determining the extent of surgery, the risk of complications should be considered. The aim of this study was to assess procedure-specific outcomes and risk factors for complications after surgery for MTC. Methods: Patients who underwent thyroid surgery for MTC were identified in two European prospec

A dopamine metabolite stabilizes neurotoxic amyloid-β oligomers

Aberrant soluble oligomers formed by the amyloid-β peptide (Aβ) are major pathogenic agents in the onset and progression of Alzheimer’s disease. A variety of biomolecules can influence the formation of these oligomers in the brain, although their mechanisms of action are still largely unknown. Here, we studied the effects on Aβ aggregation of DOPAL, a reactive catecholaldehyde intermediate of dopa

Male-male competition causes parasite-mediated sexual selection for local adaptation

Sexual selection has been suggested to accelerate local adaptation and promote evolutionary rescue through several ecological and geneticmechanisms. Condition-dependent sexual selection has mainly been studied in laboratory settings, while data from natural populations are lacking. One ecological factor that can cause condition-dependent sexual selection is parasitism. Here, we quantified ectopara

Screening Environmental Impact Reduction Enabled by Brass Reclamation through Hot Forging Operations

The traditional method for recycling brass chips is to send the scrap back to the material manufacturer for re-melting. Alternatively, brass chips can be reclaimed through hot forging operations at the production site. As an initial screening of the environmental impact of this novel reclamation method, the impacts of this new method was compared to conventional brass production (including recycli

Deterministic lateral displacement systems with arrayed three-dimensional electrodes for tunable particle sorting

Deterministic Lateral Displacement (DLD) is a passive technique employed for particles sorting. We recently introduced a DLD device composed of arrayed three-dimensional metal-covered pillars that can be used to locally apply an electric field. With our system we can exploit the dielectrophoretic (DEP) effect to exert forces on the bioparticles to be sorted, thus dynamically tuning the critical si

Enforcing the General Planar Motion Model : Bundle Adjustment for Planar Scenes

In this paper we consider the case of planar motion, where a mobile platform equipped with two cameras moves freely on a planar surface. The cameras are assumed to be directed towards the floor, as well as being connected by a rigid body motion, which constrains the relative motion of the cameras and introduces new geometric constraints. In the existing literature, there are several algorithms ava

Heritage in Action : Crafting collections between vernacular and institutional culture

This article is based on ethnographic fieldwork and applies theories of crafting and performance to explore how living heritage practices are rethought, reframed, and refashioned when traditional dress and individual garments are moved, reorganized, and transformed into a collection following rationales derived from both family tradition and museum standards. By following one woman’s emerging coll

Mortality with paclitaxel-coated devices in peripheral artery disease

BACKGROUND The results of a recent meta-analysis aroused concern about an increased risk of death associated with the use of paclitaxel-coated angioplasty balloons and stents in lower-limb endovascular interventions for symptomatic peripheral artery disease. METHODS We conducted an unplanned interim analysis of data from a multicenter, randomized, open-label, registry-based clinical trial. At the

Dealing with contaminants in Coulomb excitation of radioactive beams

Data analysis of the Coulomb excitation experiment of the exotic 206Hg nucleus, recently performed at CERN's HIE-ISOLDE facility, needs to account for the contribution to target excitation due to the strongly-present beam contaminant 130Xe. In this paper, the contamination subtraction procedure is presented.

Restoration of the electrocardiogram during mechanical cardiopulmonary resuscitation

Objective: An artefact-free electrocardiogram (ECG) is essential during cardiac arrest to decide therapy such as defibrillation. Mechanical cardiopulmonary resuscitation (CPR) devices cause movement artefacts that alter the ECG. This study analyzes the effectiveness of mechanical CPR artefact suppression filters to restore clinically relevant ECG information. Approach: In total, 495 10 s ECGs were

Response of heterogeneous rainfall variability in East Asia to Hadley circulation reorganization during the late Quaternary

The Quaternary East Asian summer rainfall evolution reconstructed with the Chinese speleothem δ18O records shows the consistency throughout the region of East Asia, and has long been considered equivalent to the monsoon intensity. Its variation and teleconnection with global climate were usually interpreted by the meridional shift of the intertropical convergence zone (ITCZ). However, many other p

Pre-processing for image quality improvement in simultaneous DBT and mechanical imaging

Simultaneous digital breast tomosynthesis (DBT) and mechanical imaging (MI) offer the potential to combine anatomic information from DBT with functional information from MI. This makes it possible to associate tissue stiffness with specific anatomic structures in the breast, a combination that can reduce false-positive findings by using the MI data to discriminate between ambiguous lesions in DBT.

Orphan G-protein coupled receptor 183 (GPR183) potentiates insulin secretion and prevents glucotoxicity-induced β-cell dysfunction

The expression and functional impact of most expression orphan G-protein coupled receptors (GPCRs) in β-cell is not fully understood. Microarray expression indicated that 36 orphan GPCRs are restricted in human islets, while 55 receptors overlapped between human islets and INS-1 cells. GPR183 showed higher expression in diabetic compared to non-diabetic human islets. GPR183 expression co-localized

Vestibular rehabilitation in Europe : a survey of clinical and research practice

Vestibular rehabilitation (VR) is practiced across Europe but little in this area has been quantified. The aim of this study was to investigate current VR assessment, treatment, education, and research practices. This was an online, cross-sectional survey with 39 VR specific questions and four sections: demographics, current practice, education, and research. The survey was disseminated through th

Molecular tests support the viability of rare earth elements as proxies for fossil biomolecule preservation

The rare earth element (REE) composition of a fossil bone reflects its chemical alteration during diagenesis. Consequently, fossils presenting low REE concentrations and/or REE profiles indicative of simple diffusion, signifying minimal alteration, have been proposed as ideal candidates for paleomolecular investigation. We directly tested this prediction by conducting multiple biomolecular assays
