The mechanism by which an apparently uniform population of cells can generate a heterogeneous population of differentiated derivatives is a fundamental aspect of pluripotent and multipotent stem cell behaviour. One possibility is that the environment and the differentiation cues to which the cells are exposed are not uniform. An alternative, but not mutually exclusive possibility is that the obser

Asteroseismology has the capability of delivering stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars. When this information is coupled with classical determinations of stellar parameters, such as metallicities, effective temperatures and angular diameters, powerful new diagnostics for stellar and Galactic studies can be obtained. The ongoing Strö

With platelet activation, there is modulation of platelet surface molecule expression. In flow cytometric analyses of in vivo platelet activation, results are often confounded by activation induced in vitro by the preparative procedures. It is particularly important therefore to prevent or retard platelet activation as soon as possible after withdrawal of the blood sample. Taking blood into parafo

Control systems can show robustness to many events, like disturbances and model inaccuracies. It is natural to speculate that they are also robust to sporadic deadline misses when implemented as digital tasks on an embedded platform. This paper proposes a comprehensive stability analysis for control systems subject to deadline misses, leveraging a new formulation to describe the patterns experienc

This paper deals with unequal error protection for code symbols of convo-lutional codes. The unequal error protection can be achieved due to different distanceproperties of output sequences and is sometimes described in terms of the correspondingeffective free distances. However, in many situations the effective free distance does notprovide enough information on the error-correcting capability. W

This paper presents the design and features of frequency-selective wallpaper-based on periodic and symmetric metallic hexagons-intended to be attached to standard walls for filtering out 5GHz signals (e.g., IEEE 802.11a systems)without blocking other selected radio communication services (e.g., cellular mobile communication signals). It analyzes the characteristics of the radio channel-as found wi

Low energy buildings are usually characterized by a very well insulated building envelope and an efficient ventilation system that makes use of the heat in the exhaust air. Internal heat gains from residents and their use of appliances can cover the heating demand to a certain extent. The magnitude of internal heat gains that cover demand are often modelled in a simplified way and thus can be asso

Understanding the etiology and meaning of behavioral symptomatology in the context of neurologic disease, and choosing the most effective intervention is a vexing task. This introduction summarizes the history of our understanding of the relationship between behavioral symptoms and primary neurologic conditions, and considers the ways in which both psychiatric and neurologic disorders occurring si

Soil microbiome is one of the most heterogeneous biological systems. State-of-the-art molecular approaches such as those based on single-amplified genomes (SAGs) and metagenome assembled-genomes (MAGs) are now improving our capacity for disentailing soil microbial-mediated processes. Here we analyzed publicly available datasets of soil microbial genomes and MAG's reconstructed from the Amazon's tr

Vi har i vår uppsats undersökt huruvida det finns korrelationssamband mellan makroekonomiskafaktorerna och pris- och omsättningsutvecklingen för villor, för perioden 1990-2002. Faktorerna har i tidsserier analyserats med hjälp av multipel regressionsanalys. Resultaten av vår undersökning tyder på att förändringar av makroekonomiska faktorer leder till förändringar på villamarknaden. Resultaten är

Syfte: Att på den svenska marknaden undersöka effekten av resultatmanipulering, efter införandet av Svensk kod för bolagsstyrning. Metod: Kvantitativ datainsamling använd's för att utföra regressioner del's för beräkning av EM, del's för identifiering av signifikanta förklaringsvariabler. Informationen hämta's bland annat från årsredovisningar, SIS Ägarservice och Datastream. Studi

BACKGROUND: Legumes are one of the most common foods causing allergic reactions in children and adults. Cross-reacting antibodies are frequently demonstrated in this family but the real clinical cross-reactivity is uncommon. OBJECTIVE: To report a case of lupine-induced anaphylaxis and to elucidate in vivo and in vitro cross-reactivity with some legumes. METHODS: Skin prick test (SPT) with some le

Indapamide is a nontiazidic sulfonamide diuretic which has not been previously reported as a cause of fixed drug eruption. We describe a patient who experienced several episodes of fixed drug eruption during treatment with indapamide. The diagnosis was confirmed by positive controlled oral challenge test. The possible existence of cross-reactivity with other sulfonamide derivatives was investigate

This article is an interdisciplinary study of CCP military decision making at the outset of the Civil War. The historical phenomenon of the Communists’ invocation of “Madrid” is studied in the context of the Chinese civil war in Manchuria, particularly the battle of Sipingjie. The strategic culture of the Communist leaders is discussed thematically in terms of their desire for a decisive battle, t

A resultant-type identity for univariate polynomials is proved and used to characterise SAGBI bases of subalgebras generated by two polynomials. A new equivalent condition, expressed in terms of the degree of a field extension, for a pair of univariate polynomials to form a SAGBI basis is derived.

BACKGROUND: Intraabdominal and retroperitoneal sarcomas (IaRS) are malignant connective tissue tumors. Surgical resection is often the only curative treatment. The primary objective was to report the mid-term outcomes following contemporary treatment protocols and identify prognostic factors.METHODS: A retrospective review of consecutive patients (n = 107) with IaRS treated at single center from 2
