Leaving Their Mark: Using Danish Student Grade Lists to Construct a More Detailed Measure of Historical Human Capital

We provide a brief overview of the educational history of Denmark and document archival and printed sources covering the development of primary, secondary, and tertiary education. In particular, we focus on student grade lists, which are available for individuals at all levels of education from the early Nineteenth century until well into the Twentieth century. We suggest that these can be used to

Should Liberal Democracy Respect Group Rights that Discriminate against Women and Apostates?

The paper examines the limits of state interference in proscribing cultural norms by considering gender discrimination, right of people to leave their community free of penalties, denying women appropriate education, and forced or arranged marriages for girls and young women. The discussion opens by reflecting on the discriminatory practices of the Pueblo tribes against their women and analysing a

Energigemenskap – olika modeller för att äga förnybar energi gemensamt

När medborgare vill gå samman och äga och producera energi gemensamt finns det olika sätt att organisera det på. I den här community briefen presenterar vi fem olika modeller av energigemenskaper. Modellerna baseras på en analys av 12 existerande solenergigemenskaper i Sverige. Genom att presentera de olika modellerna för delat ägande av förnybar energi hoppas vi kunna inspirera fler att etablera

Fatigue Reliability Based on Predicted Posterior Stress Ranges Determined from Strain Measurements of Wind Turbine Support Structures

In the present paper, an approach for updating the continuous stress range distribution of a welded connection of a wind turbine support structure with predicted information from strain measurements is presented. Environmental conditions, such as wind or, in offshore fields, waves and currents, in combination with rotor excitations generate cyclic stresses affecting the reliability of welded joint

Contactin-1 links autoimmune neuropathy and membranous glomerulonephritis

Membranous glomerulonephritis (MGN) is a common cause of nephrotic syndrome in adults, mediated by glomerular antibody deposition to an increasing number of newly recognised antigens. Previous case reports have suggested an association between patients with anti-contactin-1 (CNTN1)-mediated neuropathies and MGN. In an observational study we investigated the pathobiology and extent of this potentia

The Gaia-ESO Survey : Preparing the ground for 4MOST and WEAVE galactic surveys: Chemical evolution of lithium with machine learning

Context. With its origin coming from several sources (Big Bang, stars, cosmic rays) and given its strong depletion during its stellar lifetime, the lithium element is of great interest as its chemical evolution in the Milky Way is not well understood at present. To help constrain stellar and galactic chemical evolution models, numerous and precise lithium abundances are necessary for a large range

Chrono-chemodynamical analysis of the globular cluster NGC 6355 : Looking for the fundamental bricks of the Bulge

The information on Galactic assembly time is imprinted on the chemodynamics of globular clusters. This makes them important probes that help us to understand the formation and evolution of the Milky Way. Discerning between in-situ and ex-situ origin of these objects is difficult when we study the Galactic bulge, which is the most complex and mixed component of the Milky Way. To investigate the ear

MAXPEEM : a spectromicroscopy beamline at MAX IV laboratory

MAXPEEM, a dedicated photoemission electron microscopy beamline at MAX IV Laboratory, houses a state-of-the-art aberration-corrected spectroscopic photoemission and low-energy electron microscope (AC-SPELEEM). This powerful instrument offers a wide range of complementary techniques providing structural, chemical and magnetic sensitivities with a single-digit nanometre spatial resolution. The beaml

Energetics of Microwaves Probed by Double Quantum Dot Absorption

We explore the energetics of microwaves interacting with a double quantum dot photodiode and show wave-particle aspects in photon-assisted tunneling. The experiments show that the single-photon energy sets the relevant absorption energy in a weak-drive limit, which contrasts the strong-drive limit where the wave amplitude determines the relevant-energy scale and opens up microwave-induced bias tri

Paleoclimate evolution of the North Pacific Ocean during the late Quaternary : Progress and challenges

High- and low-latitude climatic processes in the North Pacific Ocean are important components of the global climate system. For example, the interplay among North Pacific atmospheric circulation, ocean circulation, and biological productivity affects atmospheric carbon dioxide levels and marine oxygen concentrations. Here we review recent research on the North Pacific paleoclimatic and paleoceanog

Wargaming cancer: a strategy for future precision oncology?

Development of drug resistance is a mounting problem in precision oncology, demanding a rethink of treatment strategy. We here apply concepts from military theory and espionage to the battle-like dynamics between cancer and its host, thereby identifying system vulnerabilities in cancer and ways of tricking cancer’s evolution into dead ends.

Effects of working memory load and CS-US intervals on delay eyeblink conditioning

Eyeblink conditioning is used in many species to study motor learning and make inferences about cerebellar function. However, the discrepancies in performance between humans and other species combined with evidence that volition and awareness can modulate learning suggest that eyeblink conditioning is not merely a passive form of learning that relies on only the cerebellum. Here we explored two wa

Accelerated permafrost thaw and increased drainage in the active layer : Responses from experimental surface alteration

Erosion and infrastructure in the Arctic can change the thickness of the active layer which can subsequently alternate the thermal-hydrological regime and change the drainage patterns on slopes. Previous studies have shown that drainage can either decrease due to the movement of water occurring in deeper soil layers with lower permeability or increase due to the formation of features like gullies

Genetically adjusted PSA levels for prostate cancer screening

Prostate-specific antigen (PSA) screening for prostate cancer remains controversial because it increases overdiagnosis and overtreatment of clinically insignificant tumors. Accounting for genetic determinants of constitutive, non-cancer-related PSA variation has potential to improve screening utility. In this study, we discovered 128 genome-wide significant associations (P < 5 × 10 -8) in a multi-

Percutaneous access of an intraoperatively recanalized mid-superficial femoral artery for distal lower limb revascularization

A 61-year-old male patient presented with rest pain and ulceration in his left leg 1 week after a hybrid procedure with bilateral external iliac stenting, common femoral artery thromboendarterectomy, and left-sided femoral popliteal bypass with an in situ saphenous vein. The bypass had been stented intraoperatively but had again become occluded directly after surgery. In the present report, we dem

Infective popliteal artery aneurysm by Streptococcus equi : An unusual pathogen

We report the case of a 63-year-old man who presented with a 2-week complaint of lower extremity pain, swelling, and low-grade fever after an episode of septic arthritis in the ipsilateral knee. The investigation showed a rapidly expanding popliteal artery aneurysm (PAA). The rare clinical entity of an infective PAA was suspected and was confirmed by the cultures obtained at the right femoropoplit
