Compression of Entanglement Improves Quantum Communication

Shared entanglement can significantly amplify classical correlations between systems interacting over a limited quantum channel. A natural avenue is to use entanglement of the same dimension as the channel because this allows for unitary encodings, which preserve global coherence until a measurement is performed. Contrasting this, a distributed task based on a qubit channel is demonstrated, for wh

Perceived productivity when working from home : Insights into the global experience

Purpose: This study aims to provide insights into the experiences of working from home (WFH) in a global context from the perspective of perceived productivity. Design/methodology/approach: This paper uses a multivariate analysis benefiting from an extensive data set of almost 137,500 respondents from 88 countries. Findings: This paper find that most respondents are satisfied with their productivi

Theory and Computation of Substructure Characteristic Modes

The problem of substructure characteristic modes is developed using a scattering matrix-based formulation, generalizing subregion characteristic mode decomposition to arbitrary computational tools. It is shown that the modes of the scattering formulation are identical to the modes of the classical formulation based on the background Green’s function for lossless systems under conditions where both

Supplemental oxygen for symptomatic relief in people with serious respiratory illness : a systematic review and meta-analysis

Background People with serious respiratory illness frequently have a high symptom burden and may be prescribed supplemental oxygen therapy with the aims of reducing the severity of breathlessness and improving health-related quality of life (HRQoL). This systematic review and meta-analysis aimed to assess the effectiveness of oxygen therapy versus no oxygen on 1) breathlessness, 2) HRQoL and 3) ad

Using Standards in Risk Management Regulations: a Swedish Case Study

Risk management in land-use planning often boils down to practical decision-making situations, such as deciding on safe distances between residential buildings and other types of developments and dangerous goods transportation routes or hazardous industries. The practical approaches to managing risk in land-use planning vary across countries, ranging from prescriptive regulations on managing risk

Para-crime : Notes Towards A ‘Grey Criminology’

Although criminology has long debated the so-called ‘crime drop’, the shifting nature of criminality complicates any clear-cut assessment. While some offences have decreased, this is not necessarily due to moral reform or growing securitisation but rather to transformations in crime modalities. The illicit does not simply retreat or relocate, we argue; nowadays, it increasingly adapts, embeds, and

Renal elimination and eGFR prediction of proenkephalin

Proenkephalin (PENK) is assumed to be freely filtered by the glomerulus, thus potentially useful for estimating glomerular filtration rate (eGFR). Recently developed eGFR-equation based on PENK and creatinine has not been validated against existing cystatin C-based equations. This study aimed to test the hypothesis of free filtration of PENK. Also, the PENK-creatinine based eGFR-equation was valid

Nutrient Enrichment Alters Phenotypic Selection on Plant Traits in an Annual Herb on the Tibetan Plateau

Nutrient enrichment is an increasingly important consequence of anthropogenic activities. Nutrient enrichment can alter the composition, diversity, and functioning of terrestrial plant communities, yet its effect on evolutionary processes in plant populations has been less well studied. To understand the evolutionary consequence of long-term soil nutrient enrichment, we examine the effects of nutr

Early Independent Wheeled Mobility in Children with Cerebral Palsy : A Norwegian Population-Based Registry Study

Background: The aim was to explore independent wheeled mobility in children with CP, and identify predictors of early independent wheeled mobility and changes over time across birth cohorts. Methods: We included data from the Norwegian Quality and Surveillance Registry for Cerebral Palsy (NorCP) comprising 11,565 assessments of 1780 children born in 2002–2019. Variables included demographic data,

On the Origin of Information Dynamics in Early Life

We hypothesize that predictable variations in environmental conditions caused by night/day cycles created opportunities and hazards that initiated information dynamics central to life’s origin. Increased daytime temperatures accelerated key chemical reactions but also caused the separation of double-stranded polynucleotides, leading to hydrolysis, particularly of single-stranded RNA. Daytime solar

Integrating flight mechanics, energetics and migration ecology in vertebrates

Animal locomotion is constrained by Newtonian laws of motion and therefore biomechanics is a useful approach for quantitative analysis of force and power requirements. Aerial locomotion in vertebrates is no exception, and arguably the most significant developments are to be found in this journal. Evolutionary birds and bats are very successful groups, doubtless largely because of their ability to

Signs of Hyperinflation and Ventilation Heterogeneity in Individuals With Severe Alpha-1-Antitrypsin Deficiency at the Age of 42

Background: Severe alpha-1-antitrypsin deficiency (AATD) is a known risk factor for early development of emphysema and COPD. By the Swedish national screening program within the years 1972–74 a cohort of individuals with severe AATD (PiZZ) was identified and regularly followed up. The aim of this study was to investigate alveolar volume (VA) and the ratio VA/Total lung capacity (VA/TLC) for the de

Electrographic and Clinical Determinants of Good Outcome After Postanoxic Status Epilepticus

Background and Objectives Postanoxic electrographic status epilepticus (PSE) affects up to a third of all comatose patients after cardiac arrest (CA) and is associated with high mortality. Late PSE onset (>24 hours), from a restored continuous background pattern, and absence of established indicators of poor outcome at multimodal prognostication are described in survivors. We aimed to determine th

Evaluation of Software-Optimized Protocols for Acoustic Noise Reduction During Brain MRI at 7 Tesla

Background: MR-generated acoustic noise may be particularly concerning at 7-Tesla (T) systems. Noise levels can be reduced by altering gradient output using software optimization. However, such alterations might influence image quality or prolong scan times, and these optimizations have not been well characterized. Purpose: To evaluate image quality, sound pressure levels (SPLs), and perceived noi

The role of microglia in the prion-like transmission of protein aggregates in neurodegeneration

Numerous neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis share a neuropathological hallmark: aberrant protein aggregation in the CNS. Microglia, the brain's innate immune cells, also play a pivotal role in the pathogenesis of these disorders. Multiple studies indicate that these pathological aggregates can propagate throughout the brain

Some common statistical methods for assessing rater agreement in radiological studies

Rater agreement is commonly assessed in radiologic studies concerning image quality. There are several methods of measuring rater agreement. To choose the appropriate method, the researcher needs to consider the scale of the outcome variable and the design of the study. This article provides a brief overview of available methods, focusing on the most practical and commonly used, including intracla

Why Do Some Lineages Radiate While Others Do Not? Perspectives for Future Research on Adaptive Radiations

Understanding the processes that drive phenotypic diversification and underpin speciation is key to elucidating how biodiversity has evolved. Although these processes have been studied across a wide array of clades, adaptive radiations (ARs), which are systems with multiple closely related species and broad phenotypic diversity, have been particularly fruitful for teasing apart the factors that dr
