TiSe2 has long been considered one of the best candidate materials to host the elusive excitonic insulator (EI) phase. However, a finite coupling to the lattice can generically be expected, while a lack of "smoking-gun"signatures for the importance of the electron-hole interaction in driving the phase transition has rendered it challenging to distinguish the EI from the conventional charge-density
The rheology of dense granular shear flows is influenced by friction and particle shape. We investigate numerically the impact of nonspherical particle geometries under shear on packing fraction, stress ratios, velocity fluctuations, force distribution, and dissipation mechanisms, for a wide range of inertial numbers, friction coefficients and aspect ratios. We obtain a regime diagram for the diss
A random labyrinth is a disordered environment of scatterers on a lattice. A beam of light travels through the medium, and is reflected off the scatterers. The set of illuminated vertices is studied, under the assumption that there is a positive density of points, called `normal points', at which the light behaves in the manner of a simple symmetric random walk. The ensuing `random walk in a labyr
This paper is about simple random walks on $Z^d$, $d \ge 3$, in a random field of traps, the density of which tends to zero at infinity. We distinguish between the quenched problem (when the traps are fixed) and the annealed problem (when the traps are updated each unit of time). Our goal is not only to find a criterion for zero vs. positive probability of survival, but also to show three differen
The p53 gene product is a tumour suppressor protein, and alterations of the protein are common in human cancer. Previous studies have focused on nuclear accumulation of p53. To investigate if cytoplasmic accumulation of p53 strengthens the relationships to different pathobiological variables and distant recurrence-free survival in breast cancer, tumours from 164 stage II patients were examined wit
Objective. To compare the reproducibility of the standing extended view (SEV) (also known as the standing anteroposterior view) with the semiflexed, postero-anterior view [the 'metatarsophalangeal' (MTP)] view for assessing joint space width (JSW) and osteophytes in osteoarthritis of the knee when used in a busy routine X-ray department. Methods. Forty-seven patients (24 men) had both SEV and MTP
Adaptive data-dependent allocation designs are used in phase III clinical trials having two or more competing treatments with sequential entrance of patients, in order to allocate a larger number of patients to the better treatment. The odds ratio is a popular concept for biomedical practitioners; hence, odds-ratio-based adaptive designs could be very useful in practice. Rosenberger et al. (2001)
Telomerase reverse transcriptase (TERT) activity is up-regulated in several types of tumors including glioblastoma (GBM). In the present study, 128 primary glioblastoma patients were examined for single nucleotide polymorphisms of TERT in blood and in 92 cases for TERT promoter mutations in tumors. TERT promoter mutations were observed in 86% of the tumors and of these, C228T (-124 bp upstream sta
Clinical tools to guide treatment decisions in relapsed/refractory mantle cell lymphoma (R/R MCL) are limited. Moreover, the translational potential of circulating tumor DNA (ctDNA) remains largely unproven. We designed and applied panel-based duplex sequencing of ctDNA to study molecular determinants of response and outcome in 58 patients with R/R MCL treated with venetoclax, lenalidomide, and ri
Denna avhandling undersöker hur svenska män som betalar för sex ger mening åt sina handlingar och förhåller sig till ett moraliskt sammanhang präglat av kriminalisering, stigma och offentlig fördömelse. Med utgångspunkt i antropologiska perspektiv på moral, stigma och hemlighållande förstås männens berättelser som uttryck för moraliskt arbete: det pågående, situationsbundna arbete genom vilket indThis dissertation examines how Swedish men who pay for sex make sense of their actions and orient themselves within a moral landscape marked by criminalization, stigma, and public condemnation. Drawing on anthropological approaches to morality, stigma, and secrecy, the study conceptualizes the men’s accounts as forms of “moral work”: the ongoing, situated labor through which individuals seek to su
Hur kan svenska handelsföretag bli mer konkurrenskraftiga? Ja, inte är det genom att leka följa John i priskriget med de kinesiska plattformsföretagen. Det skriver Handelns ekonomiska råd – Cecilia Hermansson, Håkan Frisén, Ulf Johansson, Elin Nilsson – i en debattartikel.
Kinesiska marknadsplattformar som Temu och Shein kan utan ansvar saluföra såväl klimatmässigt ohållbara som oetiska och osäkra produkter
BACKGROUND: Digital technologies are increasingly central to supporting autonomy, health, and social participation in later life. However, disparities persist in the ability to keep up with technological developments, affecting individuals' opportunities to benefit from digital health and social innovations.OBJECTIVE: This study aimed to investigate factors associated with individuals' self-report
The ESS linac is under construction by the ESS partner institutes (socalled In-Kind Contributors - IKC) and will operate the most powerful proton beam ever for neutron spallation source. The linac delivers 5 MW via 2 GeV protons at a repetition rate of 14 Hz at the He-cooled solid tungsten target. The pulsed neutrons, result of the spallation, will reach the science instruments after having been m
BACKGROUND: Dupuytren disease (DD) is a benign fibroproliferative disorder affecting the hand. Although diabetes mellitus is a known risk factor, the underlying mechanisms behind this association remain unclear. This study aimed to examine the relationship between glycemic control and DD in type 1 (T1D) and type 2 diabetes (T2D), and to identify other metabolic risk factors influencing DD risk.MET
Network reconfiguration can significantly increase the hosting capacity (HC) for distributed generation (DG) in radially operated systems, thereby reducing the need for costly infrastructure upgrades. However, when the objective is DG maximization, jointly optimizing topology and power dispatch remains computationally challenging. Existing approaches often rely on relaxations or approximations, ye
