The infrared spectra of water dimers formed from H2O, D 2O, and HDO in krypton matrices have been recorded. Thermal equilibria between H- and D-bonded dimers have been studied. D bonding is preferred, and H-bonded dimers are approximately 60 cm-1 less stable than D-bonded dimers. The energy difference seems to be due to the higher value of the intermolecular out-of-plane H-bond shear vibration com
The infrared spectra of the H2O, HDO, and D2O complexes with ethylene, propene, cis-2-butene, trans-2-butene, 2-methylpropene, 2-methyl-2-butene, 2,3-dimethyl-2-butene, 1,3-butadiene, benzene, and naphthalene have been recorded at temperatures from 11 to 20 K. Interaction energies have been estimated. HDO prefers to form a deuterium bond to the unsaturated molecule; however, small amounts of the h
The bromovinyl radical has been prepared by the reaction of bromine atoms with acetylene in an argon matrix at 17 K and its i.r. spectrum has been studied. The spectrum of C2HDBr• shows the presence of two isomers, indicating that the radical has an unsymmetric structure.
The infrared spectra of the water (H2O, HDO, D2O) complexes with HCl, HBr, HI Cl2, Br2, and I2 have been studied in argon matrices in the 11 to 25 K interval. In all cases, water acts as a lone-pair donor. The hydrogen halide complexes are effectively planar and rotate around the axis through the heavy atoms. For the water halogen complexes, the results are less clear, but a similar rotation, coup
ObjectiveComputerized decision‐support tools may improve diagnosis of acute myocardial infarction (AMI) among patients presenting with chest pain at the emergency department (ED). The primary aim was to assess the predictive accuracy of machine learning algorithms based on paired high‐sensitivity cardiac troponin T (hs‐cTnT) concentrations with varying sampling times, age, and sex in order to rule
To evaluate the diagnostic yield of the ECG criteria for ST-elevation myocardial infarction in a large cohort of emergency department chest pain patients, and to determine whether extended ECG criteria or reciprocal ST depression can improve accuracy. Design: Observational, register-based diagnostic study on the accuracy of ECG criteria for ST-elevation myocardial infarction. Between Jan 2010 and
The aim of this study was to describe changes in the use of accident and emergency departments in the Copenhagen Hospital Co-operation after restricted admittance to the accident and emergency department at a large Danish university hospital, Rigshospitalet (admittance only for patients transported by ambulance or presenting with a referral from a doctor).MATERIAL AND METHODS: A retrospective stud
We present a belief propagation (BP) algorithm with probabilistic data association (DA) for detection and tracking of specular multipath components (MPCs). In real dynamic measurement scenarios, the number of MPCs reflected from visible geometric features, the MPC dispersion parameters, and the number of false alarm contributions are unknown and time-varying. We develop a Bayesian model for specul
The Soviet Union is commonly cited as "totalitarian." But just how totalitarian was the Soviet Union? The modern Russian Federation? There is an ongoing debate in Georgia about the Soviet past, the role of Stalin in Georgian history, an importance of Soviet legacies in shaping the nationalist discourse after independence and etc. Various roundtables and conferences reflecting on the historical, po
The growing influence of the European Union (EU) on the international political arena and at the same time its “particular kind” of characteristics as an international player appears to be a widely debated issue among various scholars of social sciences over the last decades. During this period a wide range of theories and concepts have attributed various epithets to the EU and tried to explain it
In unicellular bacteria, the ParA and ParB proteins segregate chromosomes and coordinate this process with cell division and chromosome replication. During sporulation of mycelial Streptomyces, ParA and ParB uniformly distribute multiple chromosomes along the filamentous sporogenic hyphal compartment, which then differentiates into a chain of unigenomic spores. However, chromosome segregation must
The purpose of this paper is to discuss the problems I have encountered under the development of the theoretical perspective of my thesis. First, discourse analysis is founded in social constructionism and post-structuralistic theory. Second, discourse analysis is a concept including different perspectives, where both more critical approaches with focus on discourses as determining and more relati
