Rewetting Intensity Influences Soil Respiration and Nitrogen Availability

It is not clear how different rewetting intensities (rapid, slow or partial rewetting) influence soil respiration and nitrogen (N) availability. Moist soil left unamended or amended with low C/N faba bean residue and incubated for 21 days was dried to rapid > partial rewetting. From day 4 onwards, moisture treatments differed little in respiration rate. In unamended soils, the rewetting intensity

The Value of a New Diagnostic Test for Prostate Cancer : A Cost-Utility Analysis in Early Stage of Development

Background: Standard biopsy for prostate cancer diagnosis is an unpleasant and sometimes painful procedure with a detection rate as low as around 50%. Consequently, an accurate blood-based test would be highly desirable to improve the predictive accuracy. However, the clinical value of a new blood test for diagnosing prostate cancer depends on its sensitivity and specificity, in relation to the se

General Trends in Core-shell Preferences for Bimetallic Nanoparticles

Core-shell nanoparticles have gathered much attention of the scientific community owing to their potential applications in various fields including biomedical imaging and catalysis. Predicting core-shell preference1-3 is, however, still largely based on a few experimental observations and limited theorical studies, and hence development of new core-shell nanoparticles is normally built on a trial-

Breaking Masked and Shuffled CCA Secure Saber KEM by Power Analysis

In this paper, we show that a software implementation of CCA secure Saber KEM protected by first-order masking and shuffling can be broken by deep learning-based power analysis. Using an ensemble of deep neural networks created at the profiling stage, we can recover the session key and the long-term secret key from 257xN and 24x257xN traces, respectively, where N is the number of repetitions of th

Mapping Customer Experience of Unattended Delivery Services in E-Grocery Retail

PurposeThe purpose of this study is to empirically identify and describe customer experience of unattended delivery services in e-grocery retail, and suggest propositions for further research and development of the research area.Design/methodology/approachThis exploratory research is based on a series of qualitative interviews to explore customer experience of unattended grocery delivery services.

Sintering Mechanism of Core@Shell Metal@Metal-Oxide Nanoparticles

Adding metal-oxide shell layers is a promising route for improving the performance of metal nanoparticles (NPs) in various applications. However, despite the rapidly growing interest and a significant amount of experimental work on metal@metal-oxide NPs, computational modeling is relatively scarce, particularly on the sintering mechanism, which plays a crucial role in both the synthesis and perfor

Synthesis and characterization of Au@Zn core@shell aerosol nanoparticles generated by spark ablation and on-line PVD

An interesting subset of nanoparticles is core-shell nanoparticles: encapsulating a core particle of one material with a shell of another material can be utilized to combine and even extend the properties of the respective material. Strategies to synthesize core-shell nanoparticles in the aerosol phase remain relatively unexplored, despite the benefit of the continuous, ambient pressure nature of

Exploring unattended delivery services in e-grocery retail : A consumer-centric perspective on last-mile logistics

The retail landscape is transforming at an unprecedented speed and scale, thereby driving an unparalleled growth in last-mile delivery. The already rapidly growing online sales have been further fueled by the coronavirus pandemic. However, the share of online sales varies greatly among different retail sectors. In grocery retail, the share of online sales is still relatively low even though it is

Aspects of Endocrine Therapy in Primary Breast Cancer. Risk Profiling and Adherence Perspectives for Improving Tailored Adjuvant Treatment.

Abstract: Breast cancers are heterogeneous tumours. Prognostic markers are needed to better profile the patient´s risk, and predictive markers to indicate the expected benefit of systemic treatment. Using gene expression analyses, breast tumours can be divided into intrinsic subtypes. Immunohistochemical (IHC) markers (oestrogen and progesterone receptors (ER and PR), human epidermal growth factor

Measuring Inflation Expectations in Interwar Britain

What caused the recovery from the British Great Depression? A leading explanation - the “expectations channel” - suggests that a shift in expected inflation lowered real interest rates and stimulated consumption and investment. However, few studies have measured, or tested the economic consequences of, inflation expectations. In this paper, we collect high-frequency information from primary and se

Sticky Wages and the Great Depression: Evidence from the United Kingdom

How sticky were wages during the Great Depression? Although classic accounts emphasize the importance of nominal rigidity in amplifying deflationary shocks, the evidence is limited. In this paper, I calculate the degree of nominal wage rigidity in the United Kingdom between the wars using new granular data covering millions of wages.I find that nominal wages were more flexible downwards than in mo

T cell receptor (TCR) signaling in health and disease

Interaction of the T cell receptor (TCR) with an MHC-antigenic peptide complex results in changes at the molecular and cellular levels in T cells. The outside environmental cues are translated into various signal transduction pathways within the cell, which mediate the activation of various genes with the help of specific transcription factors. These signaling networks propagate with the help of v

Intersection of Longest Paths in a Graph

In 1966, Gallai asked whether every connected graph has a vertex that is common to all its longest paths. The answer to this question is negative. We prove that the answer is positive for outerplanar graphs. Another related question was raised in 1995 at the British Combinatorial Conference: Do any three longest paths in a connected graph have a vertex in common? We prove that, in a connected grap

Dynamic Processes in Metal-Semiconductor Nanoparticle Heterostructures

Over the last years, there have been huge research efforts in the synthesis of advanced nanoparticle heterostructures to promote their performance in photocatalysis.[1] Especially, the combination of metals with semiconductors has been identified as a potential approach to enhance the photocatalytic activity via efficient charge carrier separation enabled by plasmon- exciton coupling.[2] The physi

Changes in south-Swedish vegetation composition over the last 200 years as described by species-specific indicator and trait values and documented by museum and literature records

Vascular plant observances were compiled for 10 well-documented parishes in Scania, southernmost Sweden, from published floras, herbarium specimens, modern inventories, and a large citizen-science database to provide decade-level presence/absence data of species throughout the period 1800–2020. Species-specific plant traits and ecological indicator values were then used to examine functional and e

Nature-based shore protection against ship waves in intra-coastal fairways

Sjötrafik har alltid haft en stor betydelse för vårt samhälle genom att transportera gods och människor mellan och inom länder. Transporter till sjöss har stora fördelar associerat till relativt låga klimatutsläpp och transportkostnader. Tyvärr medför sjötrafik även en negativ påverkan på vår miljö. Den negativa påverkan kan till exempel bestå av utsläpp av luftföroreningar, tömning av ballastvatt

Prevalence and antimicrobial susceptibility level of typhoid fever in Ethiopia: A systematic review and meta-analysis

Typhoid fever continues to be a health challenge in low-and middle-income countries where access to clean water and sanitation infrastructure is scarce. The non-confirmatory diagnostic method continues to hinder effective diagnosis and treatment, ensuring in a high antimicrobial resistance. This systematic review and meta-analysis aimed to estimate the pooled prevalence and antimicrobial susceptib

Associations of work-related stress and total sleep time with cholesterol levels in an occupational cohort of Japanese office workers

OBJECTIVE: The aim of the study was to investigate the associations of total sleep time (TST) and occupational stress based on the Brief Job Stress Questionnaire (BJSQ) with cholesterol levels in an occupational cohort of Japanese office workers. METHODS: The present study is a secondary analysis of a subset of participants from a randomized controlled trial. Participants were 179 employees from 5
