Coherent multi-cell cooperative transmission, also referred to as coordinated multi-point transmission (CoMP), is a promising strategy to provide high spectral efficiency for universal frequency reuse cellular systems. To report the required channel information to the transmitter in frequency division duplexing systems, limited feedback techniques are often applied. Considering that the average ch
Based on constructal theory, five different cases with multistage bifurcations are designed as well as one case without bifurcations, and the corresponding laminar fluid flow and thermal performance have been investigated numerically. All laminar fluid flow and heat transfer results are obtained using computation fluid dynamics, and a uniform wall heat flux thermal boundary condition is applied al
Background: Alpha-1 antitrypsin (A1AT) is a protease inhibitor that protects the tissues from degradation by neutrophil elastase under certain pathological process. Alpha-1 antitrypsin deficiency (A1ATD) could associate with both lung and liver pathogenicities. Of all the deficiency alleles, Z mutant is the most common variant and causes severe complications. Here, we described a novel and quick m
Aim A defunctioning loop ileostomy in low anterior resection reduces the incidence and morbidity of an anastomotic leakage, but complications related to the stoma may occur. We explored stoma-associated complications during the stoma period and after stoma reversal. Methods A retrospective analysis of rectal cancer patients operated with low anterior resection and a defunctioning loop ileostomy at
In terrestrial organisms, sensitivity to the Earth's magnetic field is mediated by at least two different magnetoreception mechanisms, one involving biogenic ferromagnetic crystals (magnetite/maghemite) and the second involving a photo-induced biochemical reaction that forms long-lasting, spin-coordinated, radical pair intermediates. In some vertebrate groups (amphibians and birds), both mechanism
We used near-infrared spectroscopy (NIRS) to study responses to speech and music on the auditory cortices of 13 healthy full-term newborn infants during natural sleep. The purpose of the study was to investigate the lateralization of speech and music responses at this stage of development. NIRS data was recorded from eight positions on both hemispheres simultaneously with electroencephalography, e
Cellobiose dehydrogenase (CDH) has recently become a redox enzyme at focus in bioelectrochemistry especially for the construction of sugar biosensors and biofuel cell anodes. The present study shows that an increase in the CaCl2 concentration to up to 100 mM led to an increase in the maximal catalytic current generated by two different Ascomycete and one Basidiomycete CDH immobilised on a spectros
Pluripotent stem cells (embryonic stem cells, ESCs, and induced pluripotent stem cells, iPSCs) have the capacity to generate neural progenitors that are intrinsically patterned to undergo differentiation into specific neuronal subtypes and express in vivo properties that match the ones formed during normal embryonic development. Remarkable progress has been made in this field during recent years t
The acrotretide Acrotreta socialis von Seebach, 1865 has suffered a long and tumultuous history since its original description from the middle Cambrian (Guzhangian Stage) Andrarum Limestone of Bornholm, Denmark. Uncertainties regarding key morphological characters have resulted in numerous revisions and redescriptions of the species with much of the taxonomic shuffling occurring before the mid-20(
Abstract Purpose: To monitor cell death in tumors during the rejection process after treatment with an antibody radiolabeled with a β-emitter. Methods: Tumors during rejection after treatment with (177)Lu-labeled antibody BR96 and after administration of unlabeled BR96 were compared with untreated tumors from the same immunocompetent syngeneic rat tumor model. Cell death was monitored with the ter
This study assesses the environmental effects of brine discharge into the Arabian/Persian Gulf and the option of mixing with wastewater to reduce the salt content in the discharge. The Arabian Gulf region occupies about 3.3% of the world area and has 1.0, 2.0 and 2.2% of the total world population in the years 1950, 2008 and 2050 (prognosis) respectively. The study area desalination capacities wer
Background: The focus on Alzheimer's disease (AD) is shifting from dementia to the prodromal stage of the disorder, to a large extent due to increasing efforts in trying to develop disease modifying treatment for the disorder. For development of disease-modifying drugs, a reliable and accurate test for identification of mild cognitive impairment (MCI) due to AD is essential. Objective: In the pres
Human synovial joints display a characteristic anatomic distribution of arthritis e.g. rheumatoid arthritis primarily affects the metacarpophalangeal and proximal finger joints, but rarely the distal finger joints, while osteoarthritis occur in the distal and proximal finger joints. Pelvospondylitis has a selective localization to the spine and sacroiliac joints. Is this tropism due to differences
In the 1990s, Japanese energy regulators were concerned by the fact that new generations of energy using appliances and products no longer displayed successive use-phase energy efficiency improvements, such as those that characterised product development in Japan after the 1970s oil crises. Therefore, in 1999, Japan incepted its Top Runner programme, designed to rejuvenate the lost momentum. Sever
There is today a need of better prediction of part geometry regarding industrial products by simulations. There is a need for better prediction of material inflow, stresses and strains and final geometry. One way to solve this could be by using a more advanced friction model. Today a zero order friction model (Coulomb friction) is normally used. By using a friction model of higher order the fricti
Popular Abstract in Swedish Optoelektronik genomgår för närvarande en otrolig utveckling, inte minst på grund av de senaste årtiondenas kommersialisering och utveckling av hemelektronik som kompaktdiskar och digitalkameror. Denna utveckling har drivit en blomstrande global tillväxt för optoelektroniska företag som varje år utvidgar sina erbjudanden av optiska komponenter i hård konkurrens. UtvecklThe present thesis describes a number of aspects of modern electro-optical measurement technology also known as bio-photonics; this includes instrumentation, applications, sample interaction and data interpretation. The methods employed operate over several domains, and light measurements are discretized both in intensity, space, angle, time, polarization and energy. Mainly the spectral domain is
Geologists have long recognized the magnitude, abruptness, and the global pattern of the major biotic turnover across the Cretaceous–Paleogene (K–Pg) boundary approximately 65.5 million years ago. It was associated with one of the most catastrophic events in the history of life, involving mass mortality in both terrestrial and marine ecosystems globally; vast amounts of dead biomass covered the Ea
BACKGROUND: Co-morbidity with substance use disorders negatively influences overall functioning in patients with psychosis. However, frequencies and courses of risky use of alcohol, drugs and cigarettes are rarely investigated in patients at psychosis units.The purpose of this study is to describe the use of alcohol, drugs and cigarettes in patients at a psychosis unit over a 1 1/2 year period aft
The evolution of dispersal was investigated in an adaptive individual-based metapopulation model, which allowed for demographic and environmental stochasticity. The individual dispersal behaviour was determined by a one-locus genotype subjected to simple inheritance and mutation. Dispersal behaviour could therefore evolve through the genotype–phenotype mapping and the selection regimes stemming fr
