High-pressure homogenizers (HPHs) are used extensively in food-, pharma-, and biotech processing. Erosion wear is a serious concern leading to high maintenance costs and downtime. Despite this, very little is known about how operating conditions and HPH design influence wear. Guidelines for optimizing design and operation are in great need. This contribution develops a relatively simple CFD-based

Purpose:The purpose of this study is to map different kinds of tensions in product innovation and investigate how top managers use communication to shape subordinates' attention and thereby respond to these tensions.Design/methodology/approach:This study adopted an embedded case study of four innovation centers within a Nordic multinational firm.Findings:This study identifies three kinds of tensio

Classical model reduction techniques project the governing equations onto a linear subspace of the original state space. More recent data-driven techniques use neural networks to enable nonlinear projections. While those often enable stronger compression, they may have redundant parameters and lead to suboptimal latent dimensionality. To overcome these issues, we propose a multistep algorithm that

Gaussian process regression is widely applied in computational science and engineering for surrogate modeling owning to its kernel-based and probabilistic nature. In this work, we propose a Bayesian approach that integrates the variability of input data into the Gaussian process regression for function and partial differential equation approximation. Leveraging two types of observables—noise-corru

Micro-scale mechanisms, such as inter-particle and particle-fluid interactions, govern the behaviour of granular systems. While particle-scale simulations provide detailed insights into these interactions, their computational cost is often prohibitive. At a recent Lorentz Center Workshop on “Machine Learning for Discrete Granular Media”, researchers explored how machine learning approaches can aid

We use a lifting trick to show that the Beurling-Malliavin multiplier theorem extends to radial functions in several variables in a straightforward way. This simplifies an argument of Vasilyev and also answers a question of Vasilyev on the Cartwright version of the theorem.

Let f be an entire function of finite exponential type less than or equal to σ which is bounded by 1 on the real axis and satisfies f(0)=1. Under these assumptions, Hörmander showed that f cannot decay faster than cos(σx) on the interval (−π/σ,π/σ). We extend this result to the setting of de Branges spaces with cosine replaced by the real part of the associated Hermite–Biehler function. We apply t

Let f be a strictly increasing smooth function, such that f′ is comparable to a weight α′ which is locally doubling and satisfies a non-triviality condition to be explained in the paper. We construct a meromorphic inner function J, such that f−arg(J) is bounded and arg(J)′ is comparable to α′ up to polynomial loss. We give two applications of this result. The first is a sufficient density conditio

Consider a sample of apparently unrelated individuals, for which marker genotype and phenotype data is available. When individuals are sampled on phenotypes, we propose an ascertained ancestral recombination graph (ARG) that models shared ancestry of the sample chromosomes given phenotype data along a region that possibly harbors a disease susceptibility gene. The ascertained ARG is used to define

Current food systems are unsustainable, exacerbating environmental and socio-economic challenges. With 80 % of food consumed in cities, transforming urban food systems is vital. Urban food sharing initiatives (FSIs), which involve collective acts of growing, cooking, eating, and redistributing food, offer a promising alternative in sustainable urban transformations. However, FSIs often struggle to

Globally, suicide is a leading cause of mortality among teenage children and adolescents. Alcohol and other substances of abuse may influence both the decision to commit suicide and the choice of method. However, only few studies focused on toxicological findings in child suicides. The aim of this study was to map postmortem toxicological findings in child suicides in Sweden. Data on age, sex, sui

STUDY OBJECTIVES: An association between COVID-19 and obstructive sleep apnea (OSA) has been reported in literature. We aimed to address the occurrence and phenotypes of OSA in adults with a history of COVID-19 infection and its possible association with long-COVID.METHODS: In this matched case-control study, 152 individuals with a history of COVID-19 and 152 without were evaluated in a sleep labo

C1INH (C1-inhibitor) is a multifunctional SERPIN (serine protease inhibitor) that functions as a major negative regulator of the complement, coagulation, and kallikrein-kinin systems. C1INH products were originally developed for the treatment of hereditary angioedema associated with C1INH deficiency. A growing body of literature indicates that C1INH products may find utility in the management of s

Det kraftigt förändrade omvärldsläget och den nu förändrade miljön som Sveriges armé förväntas agera i ställer allt högre krav på tillgängligheten hos arméns tekniska system. En möjlig lösning för att underlätta planering och genomförande av underhåll är användningen av digitala beslutsstödsystem. Den här studien utforskar vilka funktionaliteter som bör finnas i ett beslutsstödsystem som är anpassThe significantly altered global security environment and the changing operational context in which the Swedish Army is expected to act place increasing demands on the availability of the Army’s technical systems. One possible solution to facilitate the planning and execution of maintenance is the use of digital decision support systems. This study explores which functionalities should be included

Mantelplymhypotesen har varit föremål för omfattande debatt under lång tid, ända sedan den publicerades 1971. Denna hypotes förklarar vulkanismens ursprung genom antagandet att ett extremt varmt mantelmaterial stiger upp under litosfären genom smala kanaler. Hypotesen har accepterats av geologer och har använts för att förklara vulkanism på platser som Hawaii och Island. Trots detta har hypotesen The mantle plume hypothesis has been a subject of extensive debate since its initial publication in 1971. This hypothesis posits that volcanism originates from narrow channels of exceptionally hot mantle material rising from the deep mantle to the lithosphere. While some geologists have historically supported this idea, it has encountered significant challenges, particularly in explaining the volc

This thesis focuses on developing energy barrier models that increase photovoltaic hot carrier extraction efficiency. Hot carriers are electrons containing an excess of kinetic energy and the energy required to leave the valence band. In mitigating losses and increasing the efficiency of solar cells, hot carriers offer the opportunity to extract this kinetic energy. The study of extracting the kin

We report the synthesis of highly enantiopure perdeuterated poly-L-lactic acid and poly-D-lactic acid polymers with well-defined molecular weight by polymerization of perdeuterated lactides. Enantiopure D- and L-lactic acid-d4 monomers were synthesized from sodium pyruvate-d3 using D- and L-lactate dehydrogenase enzymes (D-LDH and L-LDH) as biocatalysts. The reduced form of the co-enzyme nicot

Disaster risk reduction (DRR) strategies must actively include people with disabilities (PWD) to ensure equitable and effective preparedness. Although awareness of disability inclusion in DRR is growing, the literature remains fragmented, and no prior structured literature review has focused specifically on participatory methods involving PWD. This review addresses that gap by identifying and synt

We study correlations in the prepare-and-measure scenario when quantum communication is constrained by photon-number statistics. Such constraints are natural and practical control parameters for semi-device-independent certification in optical platforms. To analyse these scenarios, we show how semidefinite programming relaxations for noncommutative polynomial optimization can be used to bound the

In this note, we prove equicontinuity for the family of one-point densities with respect to a two-dimensional Coulomb gas at an inverse temperature β ≥ 1=2 confined by an external potential of Hele-Shaw (or quasi-harmonic) type. As a consequence, subsequential limiting Lipschitz continuous densities are defined on the microscopic scale. There are several additional results, for example comparing t
