This paper discusses signal processing methods for speech extraction in use with voice communication applications such as personal digital assistants (PDA), mobile telephone terminals and personal computers. The user is distant from the device and thus the speech signal entering the device may be subject to reverberation and may be disturbed by background noise. The proposed structure consists of

This study focuses on Seved, a segregated and socioeconomically "poor" neighborhood in the city of Malmö in Sweden. It has attracted wide media coverage, a possible consequence of which is its increased stigmatization. The wide disparity between perceived or imagined fear and the actual incidence of, or exposure to, violence attests to the important role of the media in shaping mental maps and pla

Background: General practice systems in the Nordic countries share certain common features. The sector is based on the Nordic model of a tax-financed supply of services with a political objective of equal access for all. The countries also share the challenges of increased political expectations to deliver primary prevention and increased workload as patients from hospital care are discharged earl

Surgical site infections (SSIs) are common complications after open heart surgery. Fortunately, most are superficial and respond to minor wound debridement and antibiotics. However, 1–3% of patients develop deep sternal wound infections that can be fatal. Late infections with sternocutaneous fistulas, are encountered less often, but represent a complex surgical problem. This evidence-based review

Triple-negative breast cancer (TNBC) is considered an early onset subtype of breast cancer that carries with it a poorer prognosis in young rather than older women for reasons that remain poorly understood. Hematopoiesis in the bone marrow becomes altered with age and may therefore affect the composition of tumor-infiltrating hematopoietic cells and subsequent tumor progression. In this study, we

Purpose - The purpose of this paper is to numerically investigate the heat transfer performance of aviation kerosene flowing in smooth and enhanced tubes with asymmetric fins at supercritical pressures and to reveal the effects of several key parameters, such as mass flow rate, heat flux, pressure and inlet temperature on the heat transfer. Design/methodology/approach - A CFD approach is taken and

The results of lichenological excursions of the 19th Symposium of Baltic Mycologists and Lichenologists (BMLS) in Latvia, Kurzeme region, 22–26 September 2014, are reported. A list of 290 species is presented, of which 238 are lichenized, 43 lichen-inhabiting, and nine saprotrophic fungi: ninety-one species are new to Latvia, twelve of which (Caloplaca duplicata, Cresporhaphis wienkampii, Ellisemb

InGaAs nMOSFETs with Al2O3 and HfO2 as dielectric are analyzed. The devices with Al 2O3 show a slightly better subthreshold slope. Both high-κ's have an equal transconductance frequency dispersion (gm-f). A reduction of gm-f is reached by scaling the HfO2 thickness. Positive gate stress leads to an increase in threshold voltage and subthreshold slope for all oxides. DC-gmax degradation is related

The biologically active form of vitamin D, 1α,25-dihydroxyvitamin D3 (1,25D3), has been reported to positively regulate the human cathelicidin anti-microbial peptide (CAMP) gene coding for LL-37, but the mechanisms are not completely understood. We have determined the expression of CAMP, vitamin D receptor (VDR), and the retinoid X receptor (RXR) isoforms in human skin and gingival tissue biopsies

The transcription factor Sox4 has been proposed to underlie the increased type 2 diabetes risk linked to an intronic single nucleotide polymorphism in CDKAL1. In a mouse model expressing a mutant form of Sox4, glucose-induced insulin secretion is reduced by 40% despite normal intracellular Ca2+ signaling and depolarization-evoked exocytosis. This paradox is explained by a fourfold increase in kiss

The overdamped dynamics of particles dragged by a parallel flow in a straight micro-channel in the presence of a transverse acoustophoretic force is investigated. Analytical solutions are presented in the case of plug, shear, or Poiseuille flow velocity profile. Two regimes of particle dynamics are observed, namely an early regime dominated by the local stream-wise velocity and a later regime gove

Spectral properties of the weighted Laplace operator in the presence of fractal boundaries are numerically investigated for both Neumann and Dirichlet boundary conditions. This corresponds to the characterization of heat and mass transport in microchannels with irregular and rough surfaces induced by the microfabrication process. The axial velocity field with no-slip boundary conditions, represent

The present study focuses on a manager’s understanding of leadership and how this guides – or does not guide practice. The paper reports an empirical in-depth study of a middle manager in an international manufacturing company. We link our discussion to both – the mainstream leadership studies, which assume that managers have a solid type of leadership behavior, and authors with a meaning-oriented
