Hidden Markov models are often applied in quantitative finance to capture the stylised facts of financial returns. They are usually discrete-time models and the number of states rarely exceeds two because of the quadratic increase in the number of parameters with the number of states. This paper presents an extension to continuous time where it is possible to increase the number of states with a l

The Model of Emissions of Gases and Aerosols from Nature (MEGANv2.1) together with the Modern-Era Retrospective Analysis for Research and Applications (MERRA) meteorological fields were used to create a global emission data set of biogenic volatile organic compounds (BVOC) available on a monthly basis for the time period of 1980-2010. This data set, developed under the Monitoring Atmospheric Compo

The presence of mouth alcohol (MA) during alcohol breath test for law enforcement is the most common cause of falsely high breath alcohol concentrations (BrAC). A fast and reliable test for detection of MA roadside at the scene of the act would facilitate the police efforts for proper prosecution. A tentative technique to use orally exhaled water vapour as a reference gas to position the origin of

Det övergripande syftet med artikeln är att med hjälp av en teoretisk utgångspunkt beskriva, analysera och försöka förstå varför biståndshandläggarna i sin dagliga yrkesutövning normaliserar en restriktiv hållning när äldre personer överväger en flytt till ett särskilt boende. Medan tidigare forskning i stor utsträckning har uppmärksammat på vilket sätt biståndshandläggarna tillämpar en restriktivBy applying a theoretical point of departure, the overarching aim of this article is to describe, analyze, and try to understand why care managers in their everyday occupational practice normalize the restrictive approach when older people consider relocation to a residential home. While earlier research to a large extent has drawn attention to how the care managers carry out the restrictive appro

The aim of the study was to investigate workplace incivility as a social process, examining its components and relationships to both instigated incivility and negative outcomes in the form of well-being, job satisfaction, turnover intentions, and sleeping problems. The different components of incivility that were examined were experienced and witnessed incivility from coworkers as well as supervis

This paper examines the formation and expansion of a new organizational field in experimental science: synchrotron radiation laboratories. These labs were once peripheral servants of some specialisms of solid-state physics, but over the 40 years studied they have grown into a worldwide generic resource for tens of thousands of users in a broad spectrum of disciplines. The paper uses insights prima

ABSTRACT. We present a noninvasive method to study fruit ripening. The method is based on the combination of reflectance and fluorescence spectroscopies, as well as gas in scattering media absorption spectroscopy (GASMAS). Chlorophyll and oxygen are two of the most important constituents in the fruit ripening process. Reflectance and fluorescence spectroscopies were used to quantify the changes of

Leukocytes are activated systemically and their numbers increase soon after a burn followed by a rapid decline to low normal or subnormal levels, possibly by increased extravasation. Experimental data support that an important target for such extravasation is the lungs and that leukocytes when they adhere to endothelial cells cause an increase in vascular permeability. The authors investigated a p

This article describes the results to expand and develop the use of the Satisfaction with Daily Occupations (SDO-13) Scale. Data were collected in primary care before (I) and after intervention (II) among clients with stress-related disorders and musculoskeletal pain. The Cronbach's alpha values of the SDO-13 Scale were 0.80 and 0.88. Convergent validity was assessed against global occupational sa

A total of 20 patients with a depressed fracture of the lateral tibial plateau (Schatzker II or III) who would undergo open reduction and internal fixation were randomised to have the metaphyseal void in the bone filled with either porous titanium granules or autograft bone. Radiographs were undertaken within one week, after six weeks, three months, six months, and after 12 months. The primary out

The French language is less and less used as an international scientific language and many French researchers publish their work in English. Nowadays, Annales de Chirurgie Plastique Esthétique is the only international plastic surgical journal published completely in French. The use of English loan words in French plastic surgery has never been studied.

Deep eutectic solvents (DES) resemble ionic liquids but are formed from an ionic mixture instead of being a single ionic compound. Here we present some results that demonstrate that surfactant sodium dodecyl sulfate (SDS) remains surface-active and shows self-assembly phenomena in the most commonly studied DES, choline chloride/urea. X-ray reflectivity (XRR) and small angle neutron scattering (SAN

The use of bibliometric indicators on individual and national levels has gathered considerable interest in recent years, but the application of bibliometric models for allocating resources at the institutional level has so far gathered less attention. This article studies the implementation of bibliometric measures for allocating resources at Swedish universities. Several models and indicators bas

OBJECTIVES: To examine the association between barriers in the outdoor environment and perceived quality of life (QoL) in old age and to assess whether fear of moving outdoors and unmet physical activity need contribute to this association. DESIGN: Cross-sectional. SETTING: Community and research center. PARTICIPANTS: Five hundred eighty-nine, community-dwelling people aged 75 to 81 took part in f

We explore the magnetic anisotropy of GaMnAs ferromagnetic semiconductor by Planar Hall Effect (PHE) measurements. Using low magnitude of applied magnetic field (i.e., when the magnitude H is smaller than both cubic Hc and uniaxial Hu anisotropy field), we have observed various shapes of applied magnetic field direction dependence of Planar Hall Resistance (PHR). In particular, in two regions of t

The isotope effects in formaldehyde photolysis are the key link between the delta D of methane emissions and the delta D of atmospheric in situ hydrogen production. A few recent studies have suggested that a pressure dependence in the isotopic fractionation can partly explain enrichment of deuterium with altitude in the atmosphere. The mechanism and the extent of this pressure dependency is, howev

Abstract in UndeterminedIn this paper, the agricultural status in Syria regarding virtual water flow is presented. Crop patterns, area, yield, and water consumption in agriculture are discussed. The historical change in crop pattern and the cultivated land is analyzed. The embedded water in different crops and the virtual water flow due to agriculture products were estimated. It was found that the

In this work, multi-dimensional computational fluid dynamics modeling predictions are compared for three different methods of achieving high-efficiency, low NOT, and soot premixed charge compression ignition (PCCI) combustion. The first method is early injection, highly dilute (i.e., low oxygen concentration), diesel fuel PCCI operation. In this method, the oxygen concentration is reduced to exten

Activated dynamics plays a central role in protein function, where transitions between distinct conformations often underlie the switching between active and inactive states. The characteristic time scales of these transitions typically fall in the microsecond to millisecond range, which is amenable to investigations by NMR relaxation dispersion experiments. Processes at the faster end of this ran
