Introduction: We have previously adapted a clinical linear accelerator (Elekta Precise, Elekta AB) for ultra-high dose rate (UHDR) electron delivery. To enhance reliability in future clinical FLASH radiotherapy trials, the aim of this study was to introduce and evaluate an upgraded beam control system and beam tuning process for safe and precise UHDR delivery. Materials and Methods: The beam contr

The X-ray flux provided by X-ray free-electron lasers and storage rings offers new spatiotemporal possibilities to study in-situ and operando dynamics, even using single pulses of such facilities. X-ray Multi-Projection Imaging (XMPI) is a novel technique that enables volumetric information using single pulses of such facilities and avoids centrifugal forces induced by state-of-the-art time-resolv

Bragg coherent X-ray diffraction imaging (BCDI) has emerged as a powerful technique for strain imaging and morphology reconstruction of nanometre-scale crystals. However, BCDI often suffers from angular distortions that appear during data acquisition, caused by radiation pressure, heating or imperfect scanning stages. This limits the applicability of BCDI, in particular for small crystals and high

Effectively identifying deviations in real-world medical time-series data is a critical endeavor, essential for early surveillance of disease outbreaks. This paper demonstrates the integration of time-series anomaly detection techniques to develop surveillance systems for disease outbreaks. Utilizing data from Sweden's telephone counseling service (1177), we first illustrate the trends in physical

Detta är introduktionskapitet till rapporten "DigiTrust: Tillit i det digitala. Tvärvetenskapliga perspektiv från ett forskningsprojekt", där forskargruppsledarna beskriver grunderna för projektet.

There are relatively few studies based on an individual adult perspective on ADHD which takes into account how various factors interact and affect everyday life. Compensatory strategies can facilitate life for people with ADHD and those strategies might include the use of assistive technology or cognitive support. The purpose of this paper is to present and discuss how various factors can facilita

Consider a reflected random walk Wn+1 = (W-n +X-n)(+), where X-o, X-1,... are i.i.d. with negative mean and subexponential with common distribution F. It is shown that the probability that the maximum within a regenerative cycle with mean mu exceeds x is approximately mu (F) over bar(x) as x --> infinity, and thereby that max (W-o,..., W-n) has the same asymptotics as max(X-o,...,X-n) as n --> inf

Organized human papillomavirus (HPV) vaccination was introduced in Sweden in 2012. On-demand vaccination was in effect from 2006 to 2011. We followed the HPV prevalences in Southern Sweden from 2008 to 2013.

Människans roll inom IS kan ofta falla till glömska inom organisationer som besitter en hög teknisk medvetenhet. Då utvecklingen av tekniska lösningar sker i explosionsartad takt blir möjligheten för användaren att hänga med mindre för varje ny funktion. Säkerhetsmedveten-het är därmed en fråga som bör diskuteras och göras mer aktuell inom organisationer idag då litteratur påvisar att det inte fin

Från avfall till bioetanol - en undersökning av bioetanolproduktion från djupströ Under de senaste 50 åren har befolkningen på vår planet fördubblats, vilket har lett till att energiförbrukningen har ökat drastiskt. En av de främsta bovarna är transportsektorn, som dessutom medför stora utsläpp av växthusgaser. Ett sätt att minimera dessa utsläpp är att använda sig av miljövänliga transportmedel For the year 2020, the European Union has set common goals to aim for regarding the environment. One of them being to reduce the green house gas (GHG) emissions by 20 percent. The world population is increasing, consequently increasing the demand for energy and food. Since the use of fossil sources is neither sustainable nor environmentally friendly, new techniques of meeting the energy demand nee

Popular Abstract in Swedish Den sydafrikanske författaren J. M. Coetzee, nobelpristagare 2003, är en komplex författare som räknas till en av samtidens största. Han har en unik politisk hållning i sina romaner och vägrar konsekvent att ge några enkla lösningar, istället drar han in läsaren och tvingar henne att bli delaktig i verkens problematik. I denna studie, den första avhandlingen på svenska This dissertation is a study of In the Heart of the Country (1977), Waiting for the Barbarians (1980), Age of Iron (1990), Disgrace (1999), Diary of a Bad Year (2007), and Summertime (2009) written by J. M. Coetzee. The aim of the dissertation is to analyze these works of fiction using four postcolonial aspects that function as consistent themes in the novels. The aspects are; the relationship bet

INTRODUCTION: We investigated the natural history of the relationship between PSA at age 60 and lifetime risk of prostate cancer death in an unscreened cohort followed for 40 years, the Malmö Preventive Project. We also investigated whether percent free PSA could risk-stratify men with low PSAs.METHODS: The cohort included 1162 men aged 58-62 at blood draw in 1981-82, with 1151 deaths by December

Background: While simultaneous saccharification and co-fermentation (SSCF) is considered to be a promising process for bioconversion of lignocellulosic materials to ethanol, there are still relatively little demo-plant data and operating experiences reported in the literature. In the current work, we designed a SSCF process and scaled up from lab to demo scale reaching 4% (w/v) ethanol using xylos

This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. However, one of the major

The aim of this thesis is to investigate if postcolonial structures affect international children's law in general. In order for the thesis to fulfill its purpose, I studied two children's rights documents, the CRC (Convention on the Rights of the Child) and the ACRWC (African Charter on the Rights and Welfare of the Child). The thesis aims to answer the following question: Do colonial str

Ferroelectric thin films present a powerful platform for next-generation computing and memory applications. However, domain morphology and dynamics in buried ferroelectric stacks have remained underexplored, despite their importance for real device performance. Here, nanoprobe X-ray diffraction (nano-XRD) is used to image ferroelectric domains inside BiFeO3-based capacitors, revealing local disord
