Lamniform sharks are amongst the largest-bodied extant fishes and have an evolutionary history spanning ~135 million years (Ma). Fossils correlate their initial development of mega-body size (≥ 6 m) with ecological radiation as marine top-predators during the later part of the mid-Cretaceous (after the late Albian, ~100 Ma). Here, we push back this earliest appearance of gigantic lamniforms by ~15
Background: Induced hypothermia after cardiac arrest is neuroprotective in several animal models of cardiac arrest, but few high-quality studies have been conducted in larger animals. Recent clinical trials have questioned the beneficial effects of post-ischemic hypothermia. This study investigated whether immediate cooling or a 2-h delay in cooling to 33 °C after cardiac arrest was neuroprotectiv
We propose a novel class of dark matter (DM) candidates in the form of a heavy composite axionlike particle (ALP) with highly suppressed electromagnetic interactions populating vast yet unexplored domains in the ALP parameter space. This is achieved for the first time in the simplest dark confining gauge theory yielding a new composite glueball ALP (GALP) DM coupling-mass relation found in terms o
Science is a risky business, and risk-taking is a critical disposition for scientists. This study uses a combination of survey and bibliometric data to measure the degree of individual scientists' risk-taking and investigate its determinants. In particular, we focus on academic training as a critical arena for the socialization of risk-taking and examine whether and how risk-taking is transmitted
Cutaneous endometriosis is a rare manifestation of endometriosis, and few reports on its dermoscopic features have been published. In this case report, we present a 40-year-old female with cutaneous endometriosis arising in a caesarean scar, exhibiting unique and distinct dermoscopic features. Te patient presented with a nodular, papillomatous growth in the right end of the scar, and dermoscopic e
IMPORTANCE Risk stratification strategies in primary prevention of coronary events lack precision. OBJECTIVE To determine whether prediction of first coronary events is improved by adding information on coronary atherosclerosis from coronary computed tomography angiography (CCTA) to a model using the pooled cohort equation (PCE) risk score tool and the coronary artery calcification score (CACS). D
In this paper, we revisit the question of key recovery using side-channel analysis for unrolled, single-cycle block ciphers. In particular, we study the Princev2 cipher. While it has been shown vulnerable in multiple previous studies, those studies were performed on side-channel friendly ASICs or older FPGAs (e.g., Xilinx Virtex II on the SASEBO-G board), and using mostly expensive equipment. We s
Background: Current guidelines for the treatment of severe TBI recommend maintaining a cerebral perfusion pressure (CPP) at 60–70 mmHg. In our institution, as well as others, an alternative algorithm—originally named the Lund concept—has been used. This treatment algorithm employs metoprolol and clonidine to limit CPP, accepting levels below 60 mmHg, with the aim of reducing cerebral edema. Previo
Emerging from the citizen movements of the early 2010s, New Municipalism merges the administrative capacity of municipal government with the organizational capacities of activists and social movements to build more equal, just and ecological local economies. In these contexts, Digital Municipal Currencies (DMCs) emerge as potent instruments of counter-hegemonic struggle, enabling cities to impleme
Layered transition metal dichalcogenides (TMDs) are model systems to investigate the interplay between superconductivity and the charge density wave (CDW) order. Here, we use muon spin rotation and relaxation (μ+SR) to probe the superconducting ground state of polycrystalline 2H-TaS2, which hosts a CDW transition at 76 K and superconductivity below 1 K. The μ+SR measurements, conducted down to 0.2
Modern cellular radio base stations (RBS) employ beamforming to dynamically steer radio frequency (RF) energy toward active users. This adaptive transmission produces significant angular and temporal variations in the equivalent isotropically radiated power (EIRP). To account for these variations, electromagnetic field (EMF) compliance assessment of RBSs rely on the usage of the EIRP envelope toge
Detta examensarbete utfört på uppdrag av och i samarbete med Vossloh Nordic Switch Systems AB i syfte att ta fram ett pressverktyg för montering av fjäderbefästningar (s.k. pandrolfjädrar) vilka används vid installation av järnvägsväxlar. Det verktyg som huvudsakligen används idag har inte kunnat brukas till hela produktportfolion av växlar på grund av verktygets storlek som inte tillåter åtkomst This master thesis work was carried out on behalf of and in collaboration with Vossloh Nordic Switch Systems AB with the aim of developing a pressing tool for the assembly of spring fasteners (so-called Pandrol e-clips) used in the installation of railway switches. The tool primarily used today has not been able to be used for the entire product portfolio of switches due to the tool’s size, which
The increasing presence and activities of people in both urban environments and non-urban areas result in the exposure of many wild animal populations to persistent human disturbance. As a response, individuals in disturbed populations often become tolerant towards humans, which can have significant ecological and societal consequences, for example by affecting ecosystem services and human–wildlif
This paper examines digital wellbeing as an evolving, mul-tifaceted concept shaped by technological design, data practices, and policy measures. Focusing on children and young people, it explores how digital wellbeing is governed through individual, platform, and government regulation. The technological dimension is foregrounded through well-being management tools such as screen-time dashboards, a
Population growth and climate change have accelerated groundwater depletion globally. Interferometric synthetic aperture radar (InSAR) is a fairly new satellite remote sensing technique based on SAR images that offers a high-accuracy monitoring system of land surface motion driven by groundwater level changes in time and space that can never be achieved with point-in-situ measurements. In producti
