Designing for observation

Design can be tricky for qualitative researchers who want to use observations. In the academic world we are often asked to have linear ambitions: proposals, applications, personal websites and presentations. But good practice in ethnography means documenting social life as process, not as a box, and grasping people’s active “doing” of social life rather than rendering it reducible or machinelike.

Investigating the Secondary Electron Emission of Nanomaterials Induced by a High-Resolution Proton Beam

Herein, the secondary electron emission (SEE) from 1D nanomaterials in the form of nanorods is investigated. The small beam of a 1.5 MeV +H2 hydrogen with a sub 70 nm in diameter allows studying the SEE with a very high resolution. A wide range of nanomaterials from various laboratories are studied, including thin ZnO and ZnO/GaN nanostructures grown on 1 μm thick Si3N4 membranes and thick InP, Ga

Effective persistency evaluation via exact excursion distributions for random processes and fields

Finding the probability that a stochastic system stays in a certain region of its state space over a specified time -- a long-standing problem both in computational physics and in applied and theoretical mathematics -- is approached through the extended and multivariate Rice formula. In principle, it applies to any smooth process multivariate both in argument and in value given that efficient numeFinding the probability that a stochastic system stays in a certain region of its state space over a specified time—a long-standing problem both in computational physics and in applied and theoretical mathematics—is approached through the extended and multivariate Rice formula.

Supporting Entrepreneurship and Innovation in Higher Education in Lithuania

Changes in climate, technology and demography as well as the COVID-19 pandemic are transforming our societies and way of life. The EU Member States, as elsewhere, need a strong higher education sector, as an engine of innovation and entrepreneurship and driver of skills and knowledge. As the conditions in which our societies operate are changing, there is broad consensus that higher education inst

Dissolved neodymium isotopes in the Mediterranean Sea

The neodymium isotopic composition (εNd) of seawater is one of the most important geochemical tracers to investigate water mass provenance, which can also serve as a proxy to reconstruct past variations in ocean circulation. Nd isotopes have recently also been used to reconstruct past circulation changes in the Mediterranean Sea on different time scales. However, the modern seawater εNd dataset fo

Magnetic resonance imaging of the brachial plexus. Part 2 : Traumatic injuries

The most common indications for magnetic resonance imaging (MRI) of the brachial plexus (BP) are traumatic injuries. The role of MRI of the BP has increased because of recent trends favoring earlier surgery. Determining preganglionic vs. postganglionic injury is essential, as different treatment strategies are required. Thus, MRI of the BP should be supplemented with cervical spine MRI to assess t

Establishing metastatic prostate cancer quality indicators using a modified Delphi approach

Background: There is variation in the care provided to men with metastatic prostate cancer (mPCa). There has been no previous set of quality indicators (QIs) regarding the management of men with mPCa. The objective of this study is to develop a set of international mPCa-specific QIs, which will enable global benchmarking of quality of care. Materials and methods: Potential QIs were identified thro

Personalized seizure signature : An interpretable approach to false alarm reduction for long-term epileptic seizure detection

Objective: Long-term automatic detection of focal seizures remains one of the major challenges in epilepsy due to the unacceptably high number of false alarms from state-of-the-art methods. Our aim was to investigate to what extent a new patient-specific approach based on similarly occurring morphological electroencephalographic (EEG) signal patterns could be used to distinguish seizures from nons

Assessing How Consumers Interpret and Act on Results from At-Home COVID-19 Self-test Kits : A Randomized Clinical Trial

Importance: The US Food and Drug Administration (FDA) authorized SARS-CoV-2 rapid at-home self-test kits for individuals with and without symptoms. How appropriately users interpret and act on the results of at-home COVID-19 self-tests is unknown. Objective: To assess how users of at-home COVID-19 self-test kits interpret and act on results when given instructions authorized by the FDA, instructio

ERC-ESICM guidelines on temperature control after cardiac arrest in adults

The aim of these guidelines is to provide evidence‑based guidance for temperature control in adults who are comatose after resuscitation from either in-hospital or out-of-hospital cardiac arrest, regardless of the underlying cardiac rhythm. These guidelines replace the recommendations on temperature management after cardiac arrest included in the 2021 post-resuscitation care guidelines co-issued b

The sustainability challenge of product information quality in the design and construction of facades : lessons from the Grenfell Tower fire

Purpose: This paper explores the quality and flow of facade product information and the capabilities for avoiding the risk of facade fires early in the design process. Design/methodology/approach: A qualitative case study using the process tracing method is conducted in two stages. First, a thematic analysis of reports and literature identified two categories for the problems that caused fast fire

Changes in apparent diffusion coefficient and pathological response in colorectal liver metastases after preoperative chemotherapy

Background: The pathological response to preoperative chemotherapy of colorectal liver metastases (CRLMs) is predictive of long-term prognosis after liver resection. Accurate preoperative assessment of chemotherapy response could enable treatment optimization. Purpose: To investigate whether changes in lesion-apparent diffusion coefficient (ADC) measured with diffusion-weighted magnetic resonance

Base of tongue squamous cell carcinomas, outcome depending on treatment strategy and p16 status. A population-based study from the Swedish Head and Neck Cancer Register

Background: The base of tongue squamous cell carcinoma (BOTSCC) is mainly an HPV-related tumor. Radiotherapy (EBRT) ± concomitant chemotherapy (CT) is the backbone of the curatively intended treatment, with brachytherapy (BT) boost as an option. With four different treatment strategies in Sweden, a retrospective study based on the population-based Swedish Head and Neck Cancer Register (SweHNCR) wa

On the sign recovery by least absolute shrinkage and selection operator, thresholded least absolute shrinkage and selection operator, and thresholded basis pursuit denoising

Basis pursuit (BP), basis pursuit deNoising (BPDN), and least absolute shrinkage and selection operator (LASSO) are popular methods for identifying important predictors in the high-dimensional linear regression model (Formula presented.). By definition, when (Formula presented.), BP uniquely recovers (Formula presented.) when (Formula presented.) and (Formula presented.) implies (Formula presented
