Microscopic Origin of the Logarithmic Time Evolution of Aging Processes in Complex Systems

There exists compelling experimental evidence in numerous systems for logarithmically slow time evolution, yet its full theoretical understanding remains elusive. We here introduce and study a generic transition process in complex systems, based on nonrenewal, aging waiting times. Each state n of the system follows a local clock initiated at t = 0. The random time tau between clock ticks follows t

Postglacial sedimentary and geomorphological evolution of a small sub-Antarctic fjord landscape, Stromness Bay, South Georgia

A detailed stratigraphical, palaeoecological and geomorphological reconstruction of a fjord head on South Georgia (Husvik, Stromness Bay) is presented. Six sites were chosen to reconstruct the lithostratigraphy of the area by means of coring. A maximum depth of 11m was attained and the sediments encountered vary from coarse gravel over sands to fine silts with, in some cases, intercalated peat lay

The association between self-rated health and impaired glucose tolerance in Swedish adults: A cross-sectional study

Objective. To investigate gender differences in the association between self-rated health (SRH) and impaired glucose tolerance (IGT) in subjects unaware of their glucose tolerance. Design. A cross-sectional population-based study. Setting. The two municipalities of Vara and Skovde in south-western Sweden. Subjects. A total of 2502 participants (1301 women and 1201 men), aged 30-75, were randomly s

Marital status, social capital, economic stress, and mental health: A population-based study

The associations between marital status and poor mental health are investigated, and whether social capital, trust, and economic stress attenuate the associations between marital status and poor mental health. The public health survey in Skane (southern Sweden) 2008 is a cross-sectional study including 28,198 persons aged 18-80. Logistic regression models investigate associations between marital s

Reduction of greenhouse gas emissions by wood ash application to a Picea abies (L.) Karst. forest on a drained organic soil

Wood ash additions of 3.3 and 6.6 t ha(-1) reduced greenhouse gas (GHG) emissions from a spruce forest (Picea abies) on a minerotrophic drained organic soil. Emissions of carbon dioxide (CO(2)), methane (CH(4)) and nitrous oxide (N(2)O) were measured using static dark chambers for two years following the ash treatment. The CO(2) emission from the soil was significantly reduced by 17-23% by both do

Parental history and venous thromboembolism: a nationwide study of age and sex-specific familial risks in Sweden.

Background: The value of parental history as a risk indicator for venous thromboembolism (VTE) has not been determined in a nationwide setting. Objectives: This is the first nationwide study of age and sex specific familial VTE risks in offspring of parents hospitalized for VTE. Patients/Methods: The Swedish Multigeneration Register of 0-75-year-old subjects was linked to the Hospital Discharge Re

Genotyping should be considered the primary choice for pre-treatment evaluation of thiopurine methyltransferase function.

BACKGROUND AND AIMS: A pre-treatment determination of the thiopurine S-methyltransferase (TPMT) genotype or phenotype can identify patients at risk of developing severe adverse reactions from thiopurine treatment. The risk of misclassifying a patient might be dependent on the method used. The aim of this study was to investigate the concordance between TPMT genotyping and phenotyping. METHODS: T

Tighter Relaxations for Higher-Order Models based on Generalized Roof Duality

Many problems in computer vision can be turned into a large-scale boolean optimization problem, which is in general NP-hard. In this paper, we further develop one of the most successful approaches, namely roof duality, for approximately solving such problems for higher-order models. Two new methods that can be applied independently or in combination are investigated. The first one is based on cons

Local martingales with two reflecting barriers

We give an account of the characteristics that result from reflecting a drifting local martingale (i.e. the sum of a local martingale and a multiple of its quadratic variation process) in 0 and b > 0. We present conditions which guarantee the existence of finite moments of what is required to keep the reflected process within its boundaries. Also, we derive an associated law of large numbers and a

Arsenite adsorption on cryogels embedded with iron-aluminium double hydrous oxides: Possible polishing step for smelting wastewater?

Arsenic is among the most toxic elements and it commonly exists in water as arsenite (As(III)) and arsenate (As(V)) ions. As(III) removal often requires a pre-oxidation or pH adjustment step and it is a challenge to adsorb As(III) at circumneutral pH. In this study, iron-aluminium double hydrous oxides were synthesized and incorporated into cryogels. The resulting composite cryogels were evaluated

Personality psychology as the integrative study of traits and worldviews

Personality psychology inevitably studies human beings not just as mechanical systems, but also as rational agents, whose experiences and actions are imbued with meaning. The purpose of this paper is to clarify the implications of taking this core element of personality psychology seriously, and to thereby contribute to the development of an integrative and normative framework for the field. I arg

Making sense of sensory perceptions across languages and cultures

This article has two aims: (i) to give an overview of research on sensory perceptions in different disciplines with different aims, and on the basis of that (ii) to encourage new research based on a balanced socio-sensory-cognitive approach. It emphasizes the need to study sensory meanings in human communication, both in Language with a capital L, focusing on universal phenomena, and across differ

Fc epsilon RI levels and frequencies of peripheral blood dendritic cell populations in allergic rhinitis

The dendritic cell (DC) lineage encompasses a diverse population of cells with unique subtype-specific functions. In peripheral blood, four DC subsets have been identified based on their distinct expression of CD1c, CD141, CD16, and CD123, and these subpopulations exhibit functional properties in immune responses. However, their respective roles in allergic diseases, such as rhinitis, are unclear.

Prolonged half-life and preserved enzymatic properties of factor IX selectively PEGylated on native N-glycans in the activation peptide

Current management of hemophilia B entails multiple weekly infusions of factor IX (FIX) to prevent bleeding episodes. In an attempt to make a longer acting recombinant FIX (rFIX), we have explored a new releasable protraction concept using the native N-glycans in the activation peptide as sites for attachment of polyethylene glycol (PEG). Release of the activation peptide by physiologic activators

Influence of optic flow on the control of heading and target egocentric direction during steering toward a goal

Although previous studies have shown that people use both optic flow and target egocentric direction to walk or steer toward a goal, it remains in question how enriching the optic flow field affects the control of heading specified by optic flow and the control of target egocentric direction during goal-oriented locomotion. In the current study, we used a control-theoretic approach to separate the

Giant aneurysm in the sinus of Valsalva presenting as an acute coronary symptom.

We describe an 85-year old male who was admitted to the hospital with acute coronary symptoms. Bedside echocardiography revealed a structure in the aortic root, and a computed tomography scan verified the diagnosis of an aneurysm in the sinus of Valsalva below the left coronary ostium. A coronary angiography also depicted the aneurysm clearly and clearly showed how the aneurysm compressed and disl

Vertical profiling of aerosol particles and trace gases over the central Arctic Ocean during summer

Unique measurements of vertical size-resolved aerosol particle concentrations, trace gas concentrations and meteorological data were obtained during the Arctic Summer Cloud Ocean Study (ASCOS, www.ascos.se), an International Polar Year project aimed at establishing the processes responsible for formation and evolution of low-level clouds over the high Arctic summer pack ice. The experiment was con

Analytical evaluation of nine serological assays for diagnosis of syphilis.

The diagnosis of syphilis is most frequently dependent on antibody detection with serological assays. Assays for both treponemal and non-treponemal antibodies are needed to provide a sensitive and specific diagnosis. For decades, a first screening has been done with non-treponemal assays, followed by treponemal. However, in recent years, following laboratory automation, the reverse sequence screen

Search for Pair Production of a Heavy Up-Type Quark Decaying to a W Boson and a b Quark in the lepton plus jets Channel with the ATLAS Detector

A search is presented for production of a heavy up-type quark (t') together with its antiparticle, assuming subsequent decay to a W boson and a b quark, t'(t) over bar' -> W(+)bW(-)(b) over bar. The search is based on 1.04 fb(-1) of proton-proton collisions at root s = 7 TeV collected by the ATLAS detector at the CERN Large Hadron Collider. Data are analyzed in the lepton + jets final state, chara

A somatic mutation of GFI1B identified in leukemia alters cell fate via a SPI1 (PU.1) centered genetic regulatory network.

We identify a mutation (D262N) in the erythroid-affiliated transcriptional repressor GFI1B, in an acute myeloid leukemia (AML) patient with antecedent myelodysplastic syndrome (MDS). The GFI1B-D262N mutant functionally antagonizes the transcriptional activity of wild-type GFI1B. GFI1B-D262N promoted myelomonocytic versus erythroid output from primary human hematopoietic precursors and enhanced cel
