BACKGROUND: Positive margins after breast-conserving surgery (BCS) and subsequent second surgery are associated with increased costs and patient discomfort. The aim of this study was to develop a prediction model for positive margins based on risk factors available before surgery. METHODS: Patients undergoing BCS for in situ or invasive cancer between 2015 and 2016 at site A formed a development c
Importance: Local steroid injection is commonly used in treating patients with idiopathic carpal tunnel syndrome, but evidence regarding long-term efficacy is lacking. Objective: To assess the long-term treatment effects of local steroid injection for carpal tunnel syndrome. Design, Setting, and Participants: This exploratory 5-year extended follow-up of a double-blind, placebo-controlled randomiz
Intrinsic molecular subtypes may explain marked variation between bladder cancer patients in prognosis and response to therapy. Complex testing algorithms and little attention to more prevalent, early-stage (non-muscle invasive) bladder cancers (NMIBCs) have hindered implementation of subtyping in clinical practice. Here, using a three-antibody immunohistochemistry (IHC) algorithm, we identify the
This paper presents the numerical study of soot formation and oxidation processes across different ambient temperatures (900K, 1000K, and 1100K) and oxygen levels (15% and 21% O2) using large eddy simulation coupled with a two-equation soot model. The predicted ignition delay time, lift-off length and soot distribution show good agreements with the corresponding experimental data. A stronger oxida
To limit global warming to 1.5°C, fossil fuel use must rapidly decline, but historical precedents for such large-scale transitions are lacking. Here we identify 147 historical episodes and policy pledges of fossil fuel decline in 105 countries and global regions between 1960 and 2018. We analyze 43 cases in larger systems most relevant to climate scenarios. One-half of 1.5°C-compatible scenarios e
Critical infrastructures (CIs) and the services they provide are imperative for the functioning of societies. CI safety and security have historically been addressed and regulated on a sectoral basis, despite their interdependent nature. These silo-structures potentially hinder achieving resilience from a system-of-systems governance perspective. Cross-sectoral initiatives addressing interdependen
The possibility to investigate complex magnetic profiles throughout an ultrathin magnetic film or an interface by soft x-ray resonant magnetic reflectivity is presented. The determination of in- and out-of-plane magnetic profile is shown to be possible with a subnanometer resolution by measuring the reflectivity over a wide angular range. The technique is applied to a granular magnetic multilayer
We have built a new small furnace to perform high temperature studies up to 1200°C in vacuum or in oxygen atmosphere. This furnace was originally used as a catalytic reactor optimized for the in situ X-ray Absorption Spectroscopy experiments on beamline ID24. It has now been redesigned for use on the ESRF beamline ID01 for in situ Grazing Incidence Small Angle X-ray Scattering experiments. For the
Radiocarbon (14C), as a consequence of its production in the atmosphere and subsequent dispersal through the carbon cycle, is a key tracer for studying the Earth system. Knowledge of past 14C levels improves our understanding of climate processes, the Sun, the geodynamo, and the carbon cycle. Recently updated radiocarbon calibration curves (IntCal20, SHCal20, and Marine20) provide unprecedented ac
As part of the IEA-SHC Task 41 'Solar Energy and Architecture' an international survey was carried out. This paper presents its results for Subtask B which especially focuses on methods and tools for solar design applied by architects. Building professionals, mainly architects, were contacted via email and asked to participate in a web-based questionnaire about their use of methods and tools for s
Caused by SARS-CoV-2, COVID-19 has become a severe threaten to society and human health, its epidemic control emerges as long-term issue. A sustainable epidemic and environmental transmission risk control (SEERC) in urban area is urgently needed. This work aims to conduct a new investigation on the transmission risk of SARS-COV-2 as virus/hazardous material through various environmental medias, ro
Although current LC-MS technology permits scientists to efficiently screen clinical samples in translational research, e.g., steroids, biogenic amines, and even plasma or serum proteomes, in a daily routine, maintaining the balance between throughput and analytical depth is still a limiting factor. A typical approach to enhance the proteome depth is employing offline two-dimensional (2D) fractiona
Structure–activity relationships built on descriptors of bulk and bulk-terminated surfaces are the basis for the rational design of electrocatalysts. However, electrochemically driven surface transformations complicate the identification of such descriptors. Here we demonstrate how the as-prepared surface composition of (001)-terminated LaNiO3 epitaxial thin films dictates the surface transformati
Retaining β-mannanases are glycoside hydrolases (GHs) that can potentially be applied for synthesis of glycosides by catalysis of transglycosylation reactions. A novel active-site double mutant (R171K/E205D) of the catalytic module (CM) of the family GH5 Trichoderma reesei β-mannanase (TrMan5A) was expressed in Pichia pastoris and purified. TrMan5A, CM and CM-variants R171K and R171K/E205D had pH
NTRU is a lattice-based public-key cryptosystem that has been selected as one of the Round III finalists at the NIST Post-Quantum Cryptography Standardization. Compressing the key sizes to increase efficiency has been a long-standing open question for lattice-based cryptosystems. In this paper we provide a solution to three seemingly opposite demands for NTRU cryptosystem: compress the key size, i
