This paper studies a single product setting in which a firm can source from multiple suppliers. One supplier has unreliable capacity while other suppliers are reliable but have lower product quality. The addressed context (where a case study has been made) is disruptions due to sanctions which cause failure in the supply from the unreliable source. The important question which emerges here is how
Background: In experimental studies, the apolipoprotein D (APOD) and the sigma receptor type 1 (SIGMAR1) have been related to processes of brain damage, repair and plasticity. Methods: We examined blood samples from 3081 ischemic stroke (IS) patients and 1595 control subjects regarding 10 single nucleotide polymorphisms (SNPs) in the APOD (chromosomal location 3q29) and SIGMAR1 (chromosomal locati
We are constructing a High Resolution Tomographic Scintillation Camera System for small animal imaging. The system consists of a CsI(Tl) scintillator coupled to a military surplus image intensifier with a CCD camera focused on the output window. The system operates in photons counting mode and the spatial resolution is improved by centroid calculations for every photon interaction. The system can
Popular Abstract in Swedish Inom många områden, exempelvis inom sjukvården, blir det allt vanligare med situationer där stora mängder av bilder behöver analyseras. Ofta kan dessa bildmängder vara så stora att det tar för lång tid för en människa att gå igenom dem. Till exempel kan man med hjälp av datortomografi ta tredimensionella röntgenbilder av människor, något som görs på sjukhus idag. Att gåAt the core of many computer vision models lies the minimization of an objective function consisting of a sum of functions with few arguments. The order of the objective function is defined as the highest number of arguments of any summand. To reduce ambiguity and noise in the solution, regularization terms are included into the objective function, enforcing different properties of the solution. T

Humans are able to transcend the present and mentally travel to another time, place, or perspective. Mentally projecting ourselves backwards (i.e., episodic memory) or forwards (i.e., episodic foresight) in time are crucial characteristics of the human memory system. Indeed, over the past few years, episodic memory has been argued to be involved both in our capacity to retrieve our personal past e
Evidence-based practice creates practice that integrates research-driven evidence with clinical expertise and patients' preferences in clinical decision-making. Aim: The aim of this study was to investigate and evaluate the quality and applicability of scientific research in occupational therapy intervention related to the use of everyday life occupations and client-centred practice within stroke
An experimental study of methane + air flames doped with ammonia (4370 ppm of the fuel) has been performed. The goal of this work was to analyze formation of NOx from fuel-N under well-controlled conditions. The Heat Flux method was used for stabilization of non-stretched adiabatic flames on a perforated plate burner at atmospheric pressure. Laser-saturated fluorescence (LSF) and probe sampling we
The development of neural transplantation as a treatment for Parkinson's disease has been compromised by a lack of functional efficacy and the appearance of transplant-induced motor side-effects in some patients. Since the first reports of these graft-induced dyskinesias (GID), and the realization of their impact on the progress of the field, a great deal of experimental work has been performed to
Ecology is a leading discipline in the synthesis of diverse knowledge. Ecologists have had considerable experience in bringing together diverse, multinational data sets, disciplines, and cultural perspectives to address a wide range of issues in basic and applied science. Now is the time to build on this foundation and invest in ecological synthesis through new national or international programs.
In radio communications, a set of links that can transmit in parallel with a tolerable interference is called a compatible set. Finding a compatible set with maximum weighted revenue of the parallel transmissions is an important subproblem in wireless network management. For the subproblem, there are two basic approaches to express the signal to interference plus noise ratio (SINR) within integer
Although the association between cancer and venous thromboembolism (VTE) has long been known, the mechanisms are poorly understood. Circulating tissue factor-bearing extracellular vesicles have been proposed as a possible explanation for the increased risk of VTE observed in some types of cancer. The International Society for Extracellular Vesicles (ISEV) and International Society on Thrombosis an
The molecular basis for the effectiveness of arginine-rich cell penetrating peptides (ARCPPs) traversing a cell membrane barrier is not well established. The fact that a threshold concentration of ARCPPs is required for efficient translocation in model membranes suggests cooperative action by ARCPPs. We used umbrella sampling simulations to calculate the free energies for membrane pore formation.
