An interesting class of non-Gaussian stationary processes is obtained when in the harmonics of a signal with random amplitudes and phases, one allows also for frequencies to vary randomly. In the resulting models, the statistical distribution of frequencies determines the process spectrum while the distribution of amplitudes governs the process distributional properties. Since decoupling the distr

A search is presented for the production of a single top quark via left-handed flavour-changing neutral-current (FCNC) interactions of a top quark, a gluon and an up or charm quark. Two production processes are considered: u+ g→ t and c+ g→ t. The analysis is based on proton–proton collision data taken at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. The data set correspond

OBJECTIVE: Radical prostatectomy reduces mortality among patients with localized prostate cancer, however up to 35% of patients will experience biochemical recurrence, often treated with salvage radiotherapy. The objective of the study was to investigate long-term effects of salvage radiotherapy. METHODS: A prospective, controlled, non-randomized trial at 14 Swedish center's including 4,003 patien

In this letter, we propose a class of efficient, accurate, and general methods for solving state-estimation problems with equality and inequality constraints. The methods are based on recent developments in variable splitting and partially observed Markov processes. We first present the generalized framework based on variable splitting, then develop efficient methods to solve the state-estimation

Objectives: To evaluate the total number of false-positive recalls, including radiographic appearances and false-positive biopsies, in the Malmö Breast Tomosynthesis Screening Trial (MBTST). Methods: The prospective, population-based MBTST, with 14,848 participating women, was designed to compare one-view digital breast tomosynthesis (DBT) to two-view digital mammography (DM) in breast cancer scre

A challenging question in evolutionary theory is the origin of cell division and plausible molecular mechanisms involved. Here, we made the surprising observation that complexes formed by short alpha-helical peptides and oleic acid can create multiple membrane-enclosed spaces from a single lipid vesicle. The findings suggest that such complexes may contain the molecular information necessary to in

Popular Abstract in Swedish Ett glas mjölk innehåller ungefär tusen miljarder små oljedroppar. Varje droppe är en tusendels millimeter stor. Dropparna är suspenderade i en blandning av vatten, proteiner och lösta molekyler. Små droppar av olja i vatten brukar kallas emulsioner. Emulsioner är vanliga beståndsdelar i livsmedel och finns exempelvis i allehanda mjölkprodukter, såser, smeter och dressiDifferent approaches and sub-models for the modelling of emulsification in a high-pressure homogenizer are reviewed and compared in terms of both practical aspects and how well they describe what is currently known on the emulsification process in general and on high-pressure homogenization in particular. Special effort is devoted to comparing the model developments presented in the appended paper

Gasification processes convert carbon-containing material into syngas through chemical reactions in the presence of gasifying agents such as air, oxygen, and steam. Syngas mixtures produced from such processes consist mainly of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), and methane (CH4); this gas can be directly utilised as a fuel to produce electricity or steam. Besides, it is re

Policy brief Maliha Shirzay - FINAL Unseen and Undaunted: Uzbek Women Educators Confront Gender Apartheid in Afghanistan Author: Maliha Shirzay Policy Brief Executive Summary Today, many Uzbek women continue to teach in secret under extremely challenging conditions, particularly in remote provinces such as Faryab and Jawzjan. They face severe economic hardship, psychological stress, and social iso

General Purpose Graphics Processing Units (GPGPUs) have become the prevalent processor for AI/ML and other large computational problems because parallel processing has not reached a hardware limit, unlike single-threaded processing. The goal of the thesis is to investigate the suitability of a novel SRAM architecture for implementation in a GPU without extensive GPU architecture changes. This arch

In this thesis, the effective Hamiltonian formalism is studied and applied to two-photon Rabi oscillations in hydrogen. The process occurs when two photons are absorbed or emitted simultaneously. There exist various approaches to model two-photon transitions. In this thesis, we single out essential quantum states using the projection operator technique and solve for the exact dynamics in this ess

By adapting gear changes and cruise control of a Heavy Duty Vehicle (HDV) to road inclination, fuel and time savings can be achieved. In this thesis is presented a novel method of predicting the upcoming road topography, by constructing a geographical and topographical self-learning map from which a route prediction is made. The system is designed to simultaneously produce the desired road grade o

The most common controller in the process industry today is the PID controller due to its simple structure. A regular factory may have thousands of different PID controllers in use where each of them has to be tuned to work satisfactory. Doing this manually can become both a difficult and time consuming task where some knowledge for each process is required. Therefore, it is highly beneficial to h

Purpose The EPHOR-NIGHT cohort was established to investigate how night shift work influences biological pathways and chronic disease risk using a comprehensive working-life exposome approach, focusing on cardiometabolic, mental health, cognitive and biological ageing outcomes. Participant The cohort includes 937 workers aged 20–65 years (88%female), primarily from the healthcare sector (96%) in S

Many insects have a behavioral need for the rapid detection of small moving visual targets. In dragonflies and flies, Small Target Motion Detector (STMD) neurons have been found to fill this function, but observations in Hymenopterans raise questions of whether similar neurons are present. In high order variants of these neurons, predictive response gain modulation thought to be driven by dendriti

What is required to make a manager feel satisfied with his working situation, and at the same time encourage him/her to take an active part in an effective building process? Purpose: The purp
