Readout of Quantum Screening Effects Using a Time-Dependent Probe

In voltage- and temperature-biased coherent conductors quantum screening effects occur if the conductor's transmission is energy dependent. Here, we show that an additional ac-driven terminal can act as a probe for a direct readout of such effects, hitherto unexplored. We find that screening of charges induced by the static biases impacts already their standard linear thermoelectric response coeff

More on the weak gravity conjecture via convexity of charged operators

The Weak Gravity Conjecture has recently been re-formulated in terms of a particle with non-negative self-binding energy. Because of the dual conformal field theory (CFT) formulation in the anti-de Sitter space, the conformal dimension ∆(Q) of the lowest-dimension operator with charge Q under some global U(1) symmetry must be a convex function of Q. This property has been conjectured to hold for a

Fra det syriske voldskaos er der opstået en ny litterær strømning, der er kendetegnet ved at være meget sanselig og kropslig. Død, blod og afrevne lemmer er gennemgående elementer i teksterne, der beskriver, hvordan krigen besætter hverdagen og fører helt nye lugte- og sanseindtryk med sig. Teksterne er et vidnesbyrd om volden og bryder med en litterær tradition i Syrien, hvor censur og afstraffelArticle in Danish on new Syrian literature written after the militarization of the popular uprising. As a consequence of the violence and destruction, this literature is very bodily and full of sense perceptions of the new war reality. The article presents literary examples written by the Syrian poet Rasha Omran and the Syrian novelist, poet, and journalist Khalil Sweileh.

Transient dynamics of a magnetic impurity coupled to superconducting electrodes : Exact numerics versus perturbation theory

Impurities coupled to superconductors offer a controlled platform to understand the interplay between superconductivity, many-body interactions, and nonequilibrium physics. In the equilibrium situation, local interactions at the impurity induce a transition from the spin-singlet to the spin-doublet ground state, resulting in a supercurrent sign reversal (0-π transition). In this work, we apply the

A Children's Health Perspective on Nano- and Microplastics

BACKGROUND: Pregnancy, infancy, and childhood are sensitive windows for environmental exposures. Yet the health effects of exposure to nano- and microplastics (NMPs) remain largely uninvestigated or unknown. Although plastic chemicals are a well-established research topic, the impacts of plastic particles are unexplored, especially with regard to early life exposures.OBJECTIVES: This commentary ai

Be Aware of the Indoor Air. Physicochemical Characterization of Airborne Fine Particles in Occupied Homes : Physicochemical Characterization of Airborne Fine Particles in Occupied Homes

Negative health effects of exposure to particles of outdoor origin have been confirmed by epidemiological studies. In developed countries, we spend on average 65% of our time in our homes. Thus, the properties of airborne particles indoors need to be understood. The aim of this PhD thesis was to investigate the differences in physicochemical and toxicological characteristics of fine particles (PM2.5

Genetic and environmental influences on the progression from alcohol use disorder to alcohol-related medical conditions

Background: Medical conditions related to alcohol use disorders (AUD) represent a substantial public health concern. However, only a subset of individuals with AUD develop these conditions and the extent to which genetic and environmental factors that are shared with AUD, versus those distinct from it, contribute to this progression has not yet been determined. Methods: Using data from Swedish nat

Diet and lifestyle behaviour disruption related to the pandemic was varied and bidirectional among US and UK adults participating in the ZOE COVID Study

Evidence of the impact of the COVID-19 pandemic on health behaviours in the general population is limited. In this retrospective longitudinal study including UK and US participants, we collected diet and lifestyle data pre-pandemic (896,286) and peri-pandemic (291,871) using a mobile health app, and we computed a bidirectional health behaviour disruption index. Disruption of health behaviour was h

Exploring the Associations Among Occupational Balance and Health of Adults With and Without Inflammatory Arthritis

Objective: Occupational balance is a person's subjective perception of the amount and variation of their everyday activities. Evidence suggests an association between occupational balance and health. However, the impact of arthritis on occupational balance and its association with health is unclear. This exploratory study was undertaken to examine associations between occupational balance and meas

Lose pain, lose weight, and lose both : A cohort study of patients with chronic pain and obesity using a national quality registry

Background: It is known that chronic pain makes it difficult to lose weight, but it is unknown whether obese patients (body mass index ≥30 kg/m2) who experience significant pain relief after interdisciplinary multimodal pain rehabilitation (IMMPR) lose weight. Objective: This study investigated whether obese patients with chronic pain lost weight after completing IMMPR in specialist pain units. Th

A Scenario Analysis of the Potential Effects of Decarbonization on the Profitability of the Energy-Intensive and Natural-Resource-Based Industries

The decarbonization of the energy-intensive and natural-resourced-based industries is associated with large economic costs. In this paper, I explore how decarbonization may affect the profitability and market value of these industries and their ability to attract capital to fund their decarbonization. I also discuss the possibility of compensating for the investment costs through higher prices and

A Study of the Romer and Romer Monetary Policy Shocks Using Revised Data

Romer and Romer (2004) propose a simple method to estimate monetary policy shocks using forecasts and real-time data. However, such data is not always (publicly) available, especially in a historical context. We explore the consequences of using revised data instead of the original forecast and real-time data when estimating policy shocks using the Romer and Romer framework. To this end, we estima

The Risks of Adopting the Bond Yield as the Anchor for the EU Fiscal Framework

The EU’s fiscal rules, set out in the Maastricht Treaty of 1993 and the Stability and Growth Pact of 1997, are anchored to GDP. The debt ceiling and the deficit threshold are set to 60 percent and 3 percent of GDP, respectively. Recently, prominent economists and policymakers, have argued that that the debt ceiling should be raised due to falling bond yields. By extension, this argument suggests a

Promoting outdoor recreation among older adults in Sweden : – a theoretical and empirical foundation for the development of an intervention

Background: Disengagement from outdoor recreation may diminish the positive benefits on health and well-beingin old age. The purpose of this study is to present a contextual, theoretical, and empirical rationale for anintervention, aiming to promote continued engagement in outdoor recreation for older adults in a Swedishcontext.Methods: The paper includes a contextualization of outdoor recreation

The Art of Listening in the Gospel of Matthew and Paul’s Letter to the Romans

This revised lecture highlights two aspects of listening in the Bible, that of listening as an obedient act of confession according to the Gospel of Matthew and that of listening to and interpreting the oral performance of Paul’s letter to the Romans. The former aspect is specific to the socio-religious commitment in ancient Israel and Judaism, including the Jewish Christ-believers, and identifiesThis revised lecture highlights two aspects of listening in the Bible, that of listening as an obedient act of confession according to the Gospel of Matthew and that of listening to and interpreting the oral performance of Paul’s letter to the Romans.
