On some beta ridge regression estimators : method, simulation and application

The classic statistical method for modelling the rates and proportions is the beta regression model (BRM). The standard maximum likelihood estimator (MLE) is used to estimate the coefficients of the BRM. However, this MLE is very sensitive when the regressors are linearly correlated. Therefore, this study introduces a new beta ridge regression (BRR) estimator as a remedy to the problem of instabil

Förutbestämda liv och utbildningens syfte : En litteratursociologisk läsning av Kazuo Ishiguros roman Never Let Me Go

Den här studien tar sin utgångspunkt i Kazuo Ishiguros dystopiska roman Never Let Me Go. Med teoretiskt stöd från Gert Biestas (2011) tre utbildningsdimensioner – kvalificering, socialisering och subjektifiering – samt barndomssociologins dikotomi being och becoming (Jenks 1982; James, Jenks & Prout 1998), analyseras hur romanen förhåller sig till och problematiserar relationen mellan barndom,

Low-frequency noise in ferroelectric III-V vertical gate-all-around FETs

In this letter, we demonstrate low-frequency noise (LFN) characterization of an InAs vertical gate-all-around hafnium-zirconium oxide (HZO) ferroelectric field-effect transistor (FeFET). The LFN characteristics are investigated before and after ferroelectric switching for up to 1000 cycles in the FeFET. The evolution of such cycling reveals distinct differences in the LFN for the two polarization

Evaluation of Total Column Ozone derived from CAMS against AIRS datasets across the Indian subcontinent

Present work examined the spatio-temporal variability of total column ozone (TCO) using the Copernicus Atmospheric Monitoring Service (CAMS) reanalysis dataset (2005–2020) over the Indian subcontinent. TCO data from CAMS is evaluated against the TCO from the Atmospheric Infrared Sounder (AIRS) satellite dataset using descriptive statistical analysis. CAMS TCO shows better agreement with AIRS TCO w

Wigner-function formalism for the detection of single microwave pulses in a resonator-coupled double quantum dot

Semiconductor double quantum dots (DQD) coupled to superconducting microwave resonators offer a promising platform for the detection of single microwave photons. In previous works, the photodetection was studied for a monochromatic source of microwave photons. Here, we theoretically analyze the photodetection of single microwave pulses. The photodetection in this case can be seen as a nonlinear fi

Impact of antenna pattern directivity on near-field focusing of planar array in large intelligent surface applications

Near-field focusing (NFF) is a fundamental enabler for a broad spectrum of applications utilizing large intelligent surfaces (LIS) within sub-10 GHz frequency bands. This paper investigates the impact of element pattern on NFF properties, when the LIS array is a large planar array. The NFF properties of maximum received power, focal width, and focal depth are analyzed for three typical antenna pat

The Sacred Battlefields of the Eastern Europe : The Role of Orthodox Christianity in Geopolitics

Special Issue InformationIs Orthodox Christianity primarily a tool or resource used by political entities, or does it act as an independent social force with the power to drive political outcomes? How does this religion, as a transnational force, shape global politics? The special issue "Sacred Battlefields: The Role of Orthodox Christianity in Geopolitics" seeks to address these overarching quest

Characterization of emerging non-volatile cryogenic memories

In this thesis, two emerging non-volatile memories, being the resistive random access memory and a ferroelectric capacitor were characterized at cryogenic temperatures. This was carried out due to the demand for non-volatile CMOS compatible cryogenic memories for quantum computing applications. Both devices exhibit good switching characteristics, endurance >10^7 cycles and multilevel capability. M

STEM students prefer assessment practices known to reduce the impact of test anxiety

Undergraduate introductory STEM courses often rely on few, high-stakes exams to assess student learning. This assessment strategy engenders high test anxiety and negatively impacts academic performance. We know little about how students want to be assessed—particularly those who experience high test anxiety. Applying a humanist learning framework, we asked students at a university in Norway to env

Ringön Paradis

Ringön är ett industriområde i Göteborg där traditionella verksamheter som skeppsbyggare & bilmekaniker samexisterar med konstnärer, musiker, kreativa byråer & bryggerier. Området präglas av återbruk, ”Do-it-yourself”- kultur & en livlig undergroundscen med graffiti, rave, svartklubbar & alternativa konserter. Inga bostäder planeras, då målet är att bevara områdets karaktär genom o

On the effectiveness of aerosol extinguishing agents for battery vent gases and hydrogen

It is well known that Lithium-ion batteries in thermal runaway can emit gases with high hydrogen concentrations which, in case of delayed ignition, can cause a gas explosion. Aerosol suppression agents are sometimes used to suppress fires and/or prevent ignition of released gases in such situations. The agent has been studied for suppression of fires (diffusion flames), but less is known about the

Two-Step Acoustic Cell Separation Based on Cell Size and Acoustic Impedance─toward Isolation of Viable Circulating Tumor Cells

Isolation and characterization of circulating tumor cells (CTCs) present a noninvasive alternative to monitor disease progression in individual patients. However, the heterogeneous lineage specificity of CTCs makes it difficult to isolate and identify possible CTCs by a liquid biopsy. Better label-free methods for the isolation of viable CTCs are needed. Our solution is a combined approach that is

A literature-based cost-effectiveness analysis of device-assisted suturing versus needle-driven suturing during laparotomy closure

Purpose: Small-bites suturing technique for laparotomy closure is now recommended as the standard of care. However, uptake of the practice remains slow. A medical technology called the SutureTOOL has been developed which can facilitate implementation of small-bites. The aim of the study was to compare the economic and clinical outcomes of laparotomy closure for patients using manual needle-driver

How complex are galaxies? A non-parametric estimation of the intrinsic dimensionality of wide-band photometric data

Galaxies are complex objects, yet the number of independent parameters to describe them remains unknown. We present here a non-parametric method to estimate the intrinsic dimensionality of large data sets. We apply it to wide-band photometric data drawn from the COSMOS2020 catalogue and a comparable mock catalogue from the HORIZON-AGN simulation. Our galaxy catalogues are limited in signal-to-nois

Earthworm abundance increases aggregate stability : A field study in a Mediterranean agroforestry system

Soil aggregate stability has been asserted as an indicator of soil quality. Earthworms are essential for the stability of soil aggregates due to their activities, including burrowing and organic matter decomposition. In this study, we focused on how differences in plant litter quality influences earthworm abundance and composition and, subsequently, macroaggregate stability in an agroforestry ecos

Climate change rivals fertilizer use in driving soil nitrous oxide emissions in the northern high latitudes : Insights from terrestrial biosphere models

Nitrous oxide (N2O) is the most important stratospheric ozone-depleting agent based on current emissions and the third largest contributor to increased net radiative forcing. Increases in atmospheric N2O have been attributed primarily to enhanced soil N2O emissions. Critically, contributions from soils in the Northern High Latitudes (NHL, >50°N) remain poorly quantified despite their exposure to r

Increased plasma DOPA decarboxylase levels in Lewy body disorders are driven by dopaminergic treatment

DOPA Decarboxylase (DDC) has been proposed as a cerebrospinal fluid (CSF) biomarker with increased concentrations in Lewy body disorders (LBDs) and highest levels in patients receiving dopaminergic treatment. Here we evaluate plasma DDC, measured by proximity extension assay, and the effect of dopaminergic treatment in three independent LBD (with a focus on dementia with Lewy bodies (DLB) and Park
