Infrared spectra of propanoic acid isolated in the neon and argon matrixes were obtained and studied with the aid of the DFT calculations. The geometric structures of the cyclic and open dimers of PA were elucidated. The calculations predict that among various types of the open dimers only one type with additional hydrogen bond between oxygen of hydroxyl group of a monomer and hydrogen of hydroxyl
Infrared spectra of matrix isolated formic, acetic, propionic, and butyric acids mixed with water were obtained. Combining experimental data and theoretical calculations we were able to assign spectral bands arising due to formation of 1:1 complex between water and title acids. The structure of such complexes was elucidated from theoretical and spectral data for the first time. Alternating decreas
PurposeTo describe demographic and diagnostic profiles in a national cohort of older people with intellectual disability (ID) who were prescribed antipsychotics.MethodsUsing national registers, we identified people with ID who were 55 + years in 2012 (n = 7936), as well as a subcohort with complete information on demographic factors (sex, year of birth, severity of ID, presence of behavior impairm
In this paper we describe present work on multimodal prosody bymeans of simultaneous recordings of articulation and head movements. Earlierwork has explored patterning, usage and machine-learning based detection offocal pitch accents, head beats and eyebrow beats through audiovisual recordings.Kinematic data obtained through articulography allows for more comparableand accurate measurements, as we
The aim of this work is the development of a thermodynamically consistent fully coupled thermo-viscoplastic material model for metals undergoing finite deformations. A multiplicative split of the deformation gradient into a thermal, an elastic and a plastic part is introduced, where isotropic thermal expansion and isochoric plastic deformation are assumed. The model is based on a decomposition of
Den här avhandlingen berör två olika forskningsområden som är relaterade till fysiken för nanosystem. Det första området rör kvantkorrelationer och sammanflätning mellan elektroner i nanosystem, med ett särskilt fokus på hur man kan generera elektronisk orbital sammanflätning på tidsskalor mycket kortare än dekoherenstiden och hur man kan göra detektionen av sammanflätning enklare experimentellt. This thesis addresses two different topics related to the physics of nanoscale systems. The first topic concerns quantum correlations and entanglement between electrons in solid-state systems, with a focus on how to generate electronic orbital entanglement on a sub-decoherence time scale and how to achieve experimentally more feasible entanglement detection schemes. The second topic concerns heat
Inom besöksnäringen är delningsekonomins utbredning särskilt tydlig och inom denna industri återfinns en rad företag såsom Airbnb, Vayable, Getmyboat, OffWeFly, EatWith, Uber, Fodora och Travelbuddy. Airbnb, som förmedlar uthyrning av privatpersoners bostäder som en sorts hotellrum, är kanske det mest välkända företaget. Typiskt för delningsekonomin i tjänstesektorn är digitala plattformar som sam
Massive multiple-input multiple-output (MIMO) is expected to be a vital component in future 5G systems. As such, there is a need for new modeling in order to investigate the performance of massive MIMO not only at the physical layer, but also higher up the networking stack. In this paper, we present general optimization models for massive MIMO, based on mixed-integer programming and compatible setMassive multiple-input multiple-output (MIMO) is expected to be a vital component in future 5G systems.
