Abstract in Russian В данной работе был использован фантом Алдерсон-РАНДО для экспериментального определения коэффициентов перехода для условий внешнего облучения. Были смоделированы следующие конфигурации облучения: ротационная геометрия облучения с использованием различных точечных источников (99mTc, 131I + 133Ba, 137Cs, 60Co); передне-задняя и задне-передняя геометрия облучения источником 137Cs

In this paper, we propose a preemptive test scheduling technique (a test can be interrupted and later resumed) for core-based systems with the objective to minimize the test application time. We make use of reconfigurable core test wrappers in order to increase the flexibility in the scheduling process. The advantage with such a wrapper is that it is not limited to a single TAM (test access mechan

Using examples from authentic Swedish and Czech everyday conversation, we show how absent ethnic groups are categorised. In sequences where people or groups are attributed an ethnic identity, the speakers usually start by introducing a positive "we"-concept, which is then contrasted against the negative "they"-concept. Our main question in this analysis is: How can you speak about ethnic groups so

Bertrand supergames with non- binding communication are used to study price formation and stability of collusive agreements on experimental duopoly markets. The experimental design consists of three treatments with different costs of communication: zero- cost, low- cost and high- cost. Prices are found to be significantly higher when communication is costly. Moreover, costly communication decrease

Abstract: Personality traits were assessed in 63 patients with persistent allergic or non-allergic rhinitis with the Karolinska Scales of Personality, developed with the aim of measuring psychobiological vulnerability factors, and were compared with a reference group comprising a random sample of 400 sex- and age-stratified subjects. The patients' personality profile differed slightly - within one

Extended X-ray absorption fine structure has been utilised to determine the structural parameters of the amorphous III-V semiconductors GaP, GaAs, InP and InAs. The amorphous phase was formed by ion implantation to inhibit preparation-specific artefacts associated with the alternative fabrication techniques of sputtering and evaporation. Relative to crystalline standards, increases in bond length

In this paper, we take moral agency to be that context in which a particular agent can, appropriately, be held responsible for her actions and their consequences. In order to understand moral agency, we will discuss what it would take for an artifact to be a moral agent. For reasons that will become clear over the course of the paper, we take the artifactual question to be a useful way into discus

Neurons in the hippocampus exhibit subpopulations of dendritic spines that contain endoplasmic reticulum (ER). ER in spines is important for synaptic activity and its associated Ca(2+) signaling. The dynamic distribution of ER to spines is regulated by diacylglycerol and partly mediated by protein kinase C, metalloproteinases and γ-secretase. In this study, we explored whether pharmacological acti

Particle filter methods constitute a class of iterative genetic-type algorithms which provide powerful tools for obtaining approximate solutions to non-linear and/or non-Gaussian filtering problems. The aim of this paper is to, using standard tools from probability theory, study the bias of Monte Carlo integration estimates obtained by the bootstrap particle filter. A bound on this bias, which is

Expression of transcription factor ATF3 in sensory neurons in dorsal root ganglion and in Schwann cells in sciatic nerve of diabetic (BB and Goto-Kakizaki rats; experimental models of types 1 and 2 diabetes, respectively) and healthy rats were examined by immunocytochemistry after nerve compression (silicone tube) for 3, 6 or 14 days. ATF3-stained sensory neurons in dorsal root ganglia and Schwann

A chain is no stronger than its weakest link is an old idiom that holds true for muscle biology. As the name implies, skeletal muscle's main function is to move the bones. However, for a muscle to transmit force and withstand the stress that contractions give rise to, it relies on a chain of proteins attaching the cytoskeleton of the muscle fiber to the surrounding extracellular matrix. The import

Recently, nonlinear properties of three-terminal ballistic junctions (TBJs) were predicted by theoretical calculations done by Xu, and potential applications such as rectification and logic function proposed. In that analysis the TBJ was modeled by connecting three quantum point contacts via a ballistic cavity with adiabatic boundaries, thus neglecting any backscattering of electrons. In this pape

The paper deals with domestic hot water circulation (DHWC) in residential buildings. Thermostatic circulation valves (TCV) of self-acting type can be used to assure proper temperature level in DHWC systems. A mathematic model of a DHWC system with TCV's in a 36 flat residential building is presented as well as results from steady-state and dynamic Simulations. The TCV design values used in simulat

Fifty-one teenage cases with anorexia nervosa (AN) were compared with 51 age-, sex-, and school-matched cases with respect to premorbid developmental, physical, and psychiatric problems and comorbidity at the time of examination. Almost half of the AN group consisted of the total population of AN cases in one birth cohort. There were more premorbid personality problems in the AN group. Obsessive c
