When do stable roommate matchings exist? A review

We compare different preference restrictions that ensure the existence of a stable roommate matching. Some of these restrictions are generalized to allow for indifferences as well as incomplete preference lists, in the sense that an agent may prefer remaining single to matching with some agents. We also introduce a new type of cycles and in greater detail investigate the domain of preferences that

Gradient-Based Distributed Model Predictive Control

The thesis covers different topics related to model predictive control (MPC) and particularly distributed model predictive control (DMPC). One topic of the thesis is gradient-based optimization algorithms for solving the optimization problem arising in DMPC in a distributed manner. The underlying idea is to solve the optimization problem in distributed fashion using dual decomposition, which is a

Mutations in RPGR and RP2 Account for 15% of Males with Simplex Retinal Degenerative Disease

PURPOSE. To determine the proportion of male patients presenting simplex retinal degenerative disease (RD: retinitis pigmentosa [RP] or cone/cone-rod dystrophy [COD/CORD]) with mutations in the X-linked retinal degeneration genes RPGR and RP2. METHODS. Simplex males were defined as patients with no known affected family members. Patients were excluded if they had a family history of parental consa

Measuring charm and bottom using the PHENIX silicon vertex detector

The PHENIX experiment at RHIC has embarked on a broad range of upgrades to enhance its physics reach. One of the upgrades consists of a set of silicon vertex trackers that combine to cover the pseudorapidity range − 2.4 to 2.4. A description of the vertex detectors and some of their physics goals and capabilities will be given, as well as technology choices and results from prototype components.

Marital status, social capital and health locus of control: A population-based study.

OBJECTIVES: To investigate the association between marital status and lack of internal health locus of control (HLC), taking economic stress and trust into account. STUDY DESIGN: Cross-sectional study. METHODS: The public health survey Skåne 2008 is a postal questionnaire study (55% participation rate). A random sample was invited to participate, and 28,198 individuals aged 18-80 years agre

Modulation of GABA(A) Receptors by Natural Products and the Development of Novel Synthetic Ligands for the Benzodiazepine Binding Site.

Nature provides science and society with a virtually unlimited supply of structurally diverse and biologically active molecules; the natural products. While some are directly useful in commercial applications, others are valuable for studying and understanding biological phenomena at the molecular level. An example is the signaling of nerve cells, which has been explored in considerable detail usi

Numerical Analysis of Constructal Water-Cooled Microchannel Heat Sinks with Multiple Bifurcations in the Entrance Region

The Constructal Theory is applied to obtain better thermal performance from a type of microchannel heat sink. Based on a smooth, straight, rectangular microchannel heat sink (Case 1), three different configurations of constructal multiple bifurcation are designed for the entrance region of each microchannel. These types are one bifurcation (Case 2), two bifurcations with the second placed in the f

Improved outcome in Wegener's granulomatosis and microscopic polyangiitis? A retrospective analysis of 95 cases in two cohorts

Mortality rates for Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA) have decreased after the introduction of cyclophosphamide. Standardized mortality ratio (SMR) expresses the overall mortality of patients compared with the general population. The aims of this study were to compare survival in an old and a recent cohort of patients with WG and MPA using SMR and to determine predic

A LiDAR method of canopy structure retrieval for wind modeling of heterogeneous forests

The difficulty of obtaining accurate information about the canopy structure is a current limitation towards higher accuracy in numerical predictions of the wind field in forested terrain. The canopy structure in computational fluid dynamics is specified through the frontal area density and this information is required for each grid point in the three-dimensional computational domain. By using raw

Carotid artery entrapment by the hyoid bone.

We report a patient with a transient ischemic attack presumably caused by an entrapment of the internal carotid artery by the hyoid bone and without a significant carotid artery stenosis. The patient was operated on, with a release of the right internal and external carotid artery and resection of the right greater cornu of the hyoid bone. One year after treatment, the patient has not experienced

Anomalous Zero-Bias Conductance Peak in a Nb-InSb Nanowire-Nb Hybrid Device.

Semiconductor InSb nanowires are expected to provide an excellent material platform for the study of Majorana fermions in solid state systems. Here, we report on the realization of a Nb-InSb nanowire-Nb hybrid quantum device and the observation of a zero-bias conductance peak structure in the device. An InSb nanowire quantum dot is formed in the device between the two Nb contacts. Due to the proxi

Goodpasture's syndrome with concomitant immune complex mixed membranous and proliferative glomerulonephritis

Classical Goodpasture's (GP) syndrome is a monophasic illness characterized by pulmonary hemorrhage and rapidly progressive glomerulonephritis with linear IgG deposition along the glomerular and distal tubular basement membrane and destructive necrotizing diffuse extracapillary crescentic glomerulonephritis. The majority of patients have circulating anti-glomerular basement membrane (GBM) antibodi

Unveiling Nanometer Scale Extinction and Scattering Phenomena through Combined Electron Energy Loss Spectroscopy and Cathodoluminescence Measurements

Plasmon modes of the exact same individual gold nanoprisms are investigated through combined nanometer-resolved electron energy-loss spectroscopy (EELS) and cathodoluminescence (CL) measurements. We show that CL only probes the radiative modes, in contrast to EELS, which additionally reveals dark modes. The combination of both techniques on the same particles thus provides complementary informatio

Theme vowels in North Sámi : Spanning and maximal expression

In North Sámi, certain verbal derivations can be expressed as a change of theme vowel. An investigation of these derivations leads to the conclusion that spanning, i.e. one vocabulary item spelling out two or more terminal nodes, should be included in the toolbox of Distributed Morphology. It follows that com¬petition between vocabulary items is resolved according to the Principle of Maximal Expre
