Prioritize the right energy measures in historic buildings - Approach and measure selection

The overall energy goals mean that more and more extensive measures need to be applied on buildings with varying degrees of heritage value. Previous studies show that there are a number of measures that have a beneficial impact on different parts of the energy system in historic buildings. What is now needed is a holistic approach that provides an opportunity to prioritize which measures are most

Work and everyday life in a digitalized time : Experiences of people with subjective cognitive difficulties related to neurological disorders

Introduction Digitalization has changed working life and increased cognitive demands on employees in general. Nevertheless, the consequences for employees with cognitive impairments and subjective cognitive difficulties are to a large extent unexplored. The aim of this study was to explore and describe how employees with subjective cognitive difficulties who are performing digital work tasks exper

Plasma tumour and metabolism related biomarkers AMBP, LPL and Glyoxalase I differentiate heart failure with preserved ejection fraction with pulmonary hypertension from pulmonary arterial hypertension

Background: Discrimination of heart failure with preserved ejection fraction with pulmonary hypertension (HFpEF-PH) from pulmonary arterial hypertension (PAH) is crucial for clinical management but may be challenging due to similarities in clinical and comorbid characteristics. We aimed to investigate tumour and metabolism related proteins in differentiating HFpEF-PH from PAH. Methods: Sixty-nine

Finding autonomy in activity : Development and validation of a democratic classroom survey

This paper developed a Democratic Classroom Survey to measure students' perceived democratic environment of the classroom. Perceived democratic environment is one of the most important variables for understanding classroom activity and indeed any type of group activity, but actually measuring perceptions in an objective manner has been problematic. We developed the survey items from both a strong

“More Probable than Unlikely” - : A Tale of the Blood-Brain Barrier and Mobile Communication. Dedicated to Leif G, Salford on his 80th birth day 2021-12-07.

De första levande organismerna uppstod på jorden när den funnits i 1,5 miljarder år. Under de följande tre miljarder åren bildades livet på jorden, och existerade i harmoni, med gravitation, kosmisk-strålning, elektriska och magnetiska fält och dess cyklisk-hemlighetsfulla variationer medan exponeringen från den naturlga mikrovågstrålningen var endast i storleksordningen 210-15 W/kg. Det var i deOur team of the clinical researchers in Lund, Sweden, found that electromagnetic radiation, such as those used in mobile communications, even at shallow power values, cause users’ blood albumin to leak through the blood-brain barrier “BBB” into the brain tissue. The BBB is supposed to protect the brain against unwanted and toxic molecules potentially present in the blood, to transfer to the brain

The “Managing Fatigue” Programme – Experiences Shared by participants with Multiple Sclerosis

Background: The “Managing Fatigue” program can help participants manage fatigue in their everyday lives. The programme has been proven feasible with Swedish occupational therapists, but there is a lack of knowledge of how participants experience the programme.Aim: To describe how Swedish MS participants experience the content and structure of the Swedish MF programme, as well as lessons learned fr

Accuracy of Tau Positron Emission Tomography as a Prognostic Marker in Preclinical and Prodromal Alzheimer Disease : A Head-to-Head Comparison against Amyloid Positron Emission Tomography and Magnetic Resonance Imaging

Importance: Tau positron emission tomography (PET) tracers have proven useful for the differential diagnosis of dementia, but their utility for predicting cognitive change is unclear. Objective: To examine the prognostic accuracy of baseline fluorine 18 (18F)-flortaucipir and [18F]RO948 (tau) PET in individuals across the Alzheimer disease (AD) clinical spectrum and to perform a head-to-head compa

The diagnostic and prognostic capabilities of plasma biomarkers in Alzheimer's disease

Introduction: This study investigated the diagnostic and disease-monitoring potential of plasma biomarkers in mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia and cognitively unimpaired (CU) individuals. Methods: Plasma was analyzed using Simoa assays from 99 CU, 107 MCI, and 103 AD dementia participants. Results: Phosphorylated-tau181 (P-tau181), neurofilament light, amyloid-

Reconstructing an S-box from its Difference Distribution Table

In this paper we study the problem of recovering a secret S-box from its difference distribution table (DDT). While being an interesting theoretical problem on its own, the ability to recover the S-box from the DDT of a secret S-box can be used in cryptanalytic attacks where the attacker can obtain the DDT (e.g., in Bar-On et al.’s attack on GOST), in supporting theoretical analysis of the propert

Simultaneous quantitative detection of hcn and c2h2 in combustion environment using tdlas

Emission of nitrogen oxides (NOx ) and soot particles during the combustion of biomass fuels and municipal solid waste is a major environmental issue. Hydrogen cyanide (HCN) and acetylene (C2H2 ) are important precursors of NOx and soot particles, respectively. In the current work, infrared tunable diode laser absorption spectroscopy (IR-TDLAS), as a non-intrusive in situ technique, was applied to

Tau pathology mediates age effects on medial temporal lobe structure

Hippocampal atrophy is endemic in ‘normal aging’ but it is unclear what factors drive age-related changes in medial temporal lobe (MTL) structural measures. We investigated cross-sectional (n = 191) and longitudinal (n = 164) MTL atrophy patterns in cognitively normal older adults from ADNI-GO/2 with no to low cerebral β-amyloid and assessed whether white matter hyperintensities (WMHs) and cerebro

Empirical Dynamic Modeling for Low-Altitude UAV Propagation Channels

During the last few years, with the decrease of their sizes and costs, Unmanned Aerial Vehicles (UAVs) became more feasible for their use in general-purpose applications. As an important basis for UAV applications, the Air-to-Ground (A2G) radio propagation channel has gained attention in the channel modeling literature. However, whereas the A2G propagation channel is inherently dynamic (time-varyi

Air-to-Ground Channel Characterization for Low-Height UAVs in Realistic Network Deployments

Due to the decrease in cost, size, and weight, unmanned aerial vehicles (UAVs) are becoming more and more popular for general-purpose civil and commercial applications. Provision of communication services to UAVs both for user data and control messaging by using off-the-shelf terrestrial cellular deployments introduces several technical challenges. In this article, an approach to the air-to-ground

Trajectory-Aided Maximum-Likelihood Algorithm for Channel Parameter Estimation in Ultrawideband Large-Scale Arrays

Millimeter-wave with ultrawide bandwidth available and ability to pack massive number of antennas in a small area is considered the key enabler for future generation communication systems. Accurate understanding and modeling of the ultrawideband propagation channel with large-scale array configuration is essential. In this contribution, a realistic spherical-propagation signal model considering th

A USRP-Based Channel Sounder for UAV Communications

The unmanned-aerial-vehicle (UAV) has attracted great interests in both civil and military applications, due to its low cost, flexibility and ability to establish seamless coverage. In this paper, a Universal Software-defined Radio Peripheral (USRP) based channel sounding system for characterizing the UAV communication channel is introduced, which can be applied in both active and passive measurem

Extracellular vesicles in Shiga toxin-mediated disease

Extracellular vesicles are released during infectious, inflammatory and prothrombotic conditions. These are membrane-derived vesicles shed by cells during activation, senescence and/or apoptosis. Extracellular vesicles contain and transfer components of the parent cell from which they are shed. During gastrointestinal infection with enterohemorrhagic Escherichia coli (EHEC) extracellular vesicles

Precarious employment and psychosocial hazards : A cross-sectional study in Stockholm county

Precarious employment (PE) has been linked to adverse health effects, possibly mediated through psychosocial hazards. The aim of this cross-sectional study is to explore if higher levels of PE are associated with psychosocial hazards (experiences of violence, sexual harassment, bullying, discrimination, high demands, and low control) and to explore gender differences in these patterns.
