The distribution of the longitudes of solar flares associated with the high-energy proton events called ground level events (GLEs) can be approximated by a Gaussian with a peak at ∼W60, with a full range from ∼E90 to ∼W150. The longitudes of flares associated with the top third (24 of 72) of GLEs in terms of their >430 MeV fluences (F 430) are primarily distributed over E20-W100 with a skew toward

Bone is a dynamic tissue with a quarter of the trabecular and a fifth of the cortical bone being replaced continuously each year in a complex process that continues throughout an individual’s lifetime. Bone has an important role in homeostasis of minerals with non-stoichiometric hydroxyapatite bone mineral forming the inorganic phase of bone. Due to its crystal structure and chemistry, hydroxyapat

Graffiti game boards attest to the presence of historical populations at an archaeological site and, in some cases, assist in dating an archaeological context. While games suggest the presence of a social activity, their contextual significance compared to the graffiti of texts and images, pottery finds, and other diagnostic tools of archaeology is open to further enquiry. The presence of multiple

A push-pull oscillator topology that uses only one type of active device is proposed in this article. A magnetic transformer is leveraged to set positive feedback around a common-collector differential npn transistor pair, implementing the push-pull operation. This results in half the bias current for a given amplitude of oscillation, compared to more standard oscillator topologies. A thorough pha

Abstract Objectives: The area of regenerative work is still close to unexplored. The aim was to explore the possibility for employees to gain energy at work. Methods: Questionnaire to all employees (n = 599) from different professions in public and private primary health care centers in one health care district in Sweden. The questionnaire, which had a salutogenic perspective, included information

Purpose: Personalized cancer treatment requires predictive biomarkers, including image-based biomarkers. Breast cancer (BC) patients receiving neoadjuvant chemotherapy (NACT) are in a clinically vulnerable situation with the tumor present. This study investigated whether mammographic density (MD), assessed pre-NACT, is predictive of pathological complete response (pCR). Methods: A total of 495 BC

The article challenges the theoretical “sectoral model” of civil society through a historical case study and offers an alternative actor-centered approach inspired by American pragmatism. First, three separate strands of research are identified that each conceptualize civil society as a sector with institutional independence, a single normative logic, and fixed roles. Building on archival material

The pancreas is particularly sensitive to acute cellular stress, but this has been difficult to evaluate using light microscopy. Pancreatic ischaemia associated with deceased organ donation negatively impacts whole-organ and isolated-islet transplantation outcomes. Post-mortem changes have also hampered accurate interpretation of ante-mortem pancreatic pathology. A rigorous histological scoring sy

Aim: The primary aim was to compare the 30-day morbidity and mortality in patients aged ≥80 years undergoing surgery for colorectal cancer with those aged

Objective: Dose optimization and pharmacokinetic evaluation of α-particle emitting radium-223 dichloride (223RaCl2) by planar γ-camera or single photon emission computed tomography (SPECT) imaging are hampered by the low photon abundance and injected activities. In this study, we demonstrate SPECT of 223Ra using phantoms and small animal in vivo models. Methods: Line phantoms and mice bearing 223R

Fire safety provisions in building regulation are about managing risk. In order to appropriately characterize and incorporate risk measures into building regulation, it is helpful to view building regulatory systems (BRS) as complex socio-technical systems (STS), wherein there are interactions between institutions, technology and people, which ideally work together to mitigate risk to a societally

The clinical value of the polygenetic component of blood pressure (BP) is commonly questioned. We evaluated a genetic risk score for BP (BP-GRS858), based on the most recently published genome-wide association studies variants that were significantly associated with either systolic BP or diastolic BP, for prediction of hypertension and cardiovascular end points. The genotyping was performed in 2 u

Time perspective has been recognized as an important psychological dimension with a pervasive and powerful influence on human behavior. To the authors’ knowledge, no studies have focused on the relationship between time perspective and cyberbullying behavior. The first aim of this research is to fill this gap by investigating the relationship between different time perspectives and both cyberbully

Drainage networks delineated from Digital Elevation Models (DEMs), are the basis for the modelling of geomorphological and hydrological processes, biogeochemical cycling, and water resources management. Besides providing effective models of water flows, automatically extracted drainage networks based on topography can diverge from reality to varying degrees. The variability of such disagreement wi

Background: Gallbladder cancer (GBC) has a poor prognosis. The aim was to develop and validate a preoperative risk score for incidental gallbladder cancer (IGBC) in patients scheduled for cholecystectomy. Methods: Data registered in the nationwide Swedish Registry for Gallstone Surgery (GallRiks) was analyzed, including the derivation cohort (n = 28915, 2007–2014) and the validation cohort (n = 78

We report thermometry and new Raman linewidth data using a novel method for time-domain rotational coherent anti-Stokes Raman spectroscopy (RCARS) on single-shot basis. The coherences are generated by two fs pulses and probed by a ns pulse. The resulting signal is detected using a combined spectrograph/streak camera setup with high spectral and temporal resolution. Rotational CARS spectrograms of

Summary: Background: Diabetes mellitus (DM) is a risk factor for peripheral arterial disease (PAD). Indications for open surgery in infrainguinal intermittent claudication (IC) are limited, and reports are lacking regarding outcomes in DM patients. Study aims were to compare short and long-term effects on major adverse cardiovascular events (MACE), acute myocardial infarction (AMI), stroke, major

Background: The coronavirus disease 2019 (COVID-19) pandemic calls for effective and safe treatments. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing COVID-19 actively replicates in the throat, unlike SARS-CoV, and shows high pharyngeal viral shedding even in patients with mild symptoms of the disease. HCoV-229E is one of four coronaviruses causing the common cold. In this stu

Ammonia (NH3) is considered a promising alternative fuel, capable of producing energy with zero CO2 emissions. Its combustion, however, poses a series of challenges due to the low reactivity of NH3 and the formation of very high quantities of NOx. This work numerically investigates the combustion and emission characteristics of ammonia in three modern stationary gas turbine concepts, namely (a) le
