The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. All these situations require good calculation methods. The main
The capacity of downlink cellular multiple-input multiple-output (MIMO) systems, where co-channel interference is the dominant. channel impairment, is investigated in this paper, mainly from a signal-processing perspective. Turbo space-time multiuser detection (ST MUD) is employed for intracell communications and is shown to closely approach the ultimate capacity limits in Gaussian ambient noise f
We present detailed low-temperature transport measurements of a single quantum dot formed in an InGaAs/InP heterostructure with a strong tunnel coupling to the source and drain leads. The conventional spin-1/2 Kondo effect is observed for the quantum dot in the N = 9 charge state. By changing the voltages applied to the quantum dot barrier gates, we find a zero-field splitting of the Kondo resonan
The response of electric devices to an applied thermal gradient has, so far, been studied almost exclusively in two-terminal devices. Here we present measurements of the response to a thermal bias of a four-terminal, quasiballistic junction with a central scattering site. We find a novel transverse thermovoltage measured across isothermal contacts. Using a multiterminal scattering model extended t
The biochemistry and molecular genetics underlying the related carbohydrate blood group antigens P, P(k), and LKE in the GLOB collection and P1 in the P blood group system are complex and not fully understood. Individuals with the rare but clinically important erythrocyte phenotypes P(1)k and P(2)k lack the capability to synthesize P antigen identified as globoside, the cellular receptor for Parvo
The overall aim of this thesis was to study life satisfaction (LS) and factors associated to LS in the group aged 78 and above. As an aid in interpreting the findings, Baltes’ and Baltes’ theory of selective optimisation with compensation (SOC) was used. All four studies included the same studypopulation who were followed for three years in the study Good Aging in Skåne, a national, randomized, po
The present communication reviews reasons to perform rescreening of chlamydia-infected persons. It brings up difficulties to differentiate between relapse and reinfection. Studies on follow-up of chlamydia-positive cases after therapy are reviewed. It also highlights reasons for therapeutic failure, like compliance, pharmacological factors, including poor bioavailability, wrong dose regimens, lack
Abstract in Undetermined BACKGROUND: The absence of all Kell blood group antigens (K0 phenotype) is very rare. K0 persons, however, can produce clinically significant anti-Ku (K5) after transfusion and/or pregnancy and require K0 blood for transfusion. Ten alleles giving rise to the K0 phenotype have been reported: different populations were studied although none from Scandinavia. STUDY DESIGN AND
Human papillomavirus type 16 (HPV-16) is a major cause of human cancer. Effective prophylactic vaccines are based on type-specific neutralizing antibodies. A major neutralizing epitope has been defined by the monoclonal antibody H16.V5. To investigate the importance of this epitope for overall immunogenicity of HPV-16, HPV-16 virus-like particles devoid of the H16.V5 epitope were engineered by sit
We have studied the atomic scale structure of molecular beam epitaxy grown Ga1-xMnxAs compounds with various Mn concentrations by cross-sectional scanning tunneling microscopy and first principles calculations. Only bright protrusions close to the top layer As atoms are directly correlated with the bulk Mn concentration. Atomically resolved filled and empty states images of this defect are compare
Popular Abstract in Swedish I många utvecklingsländer i tropiska klimat leder den snabba urbaniseringen till många problem, bl a försämrad termisk komfort i utemiljön. Detta har negativa följder för människors hälsa och välbefinnande och påverkar sociala och kommersiella aktiviteter utomhus negativt. Följaktligen är det mycket viktigt att åstadkomma komfortabla mikroklimat i urban miljö. Den huvuIn many developing tropical countries, rapid urban growth leads to several problems, including increased thermal stress. This has negative consequences for people's health and well-being, and affects social and commercial outdoor activities negatively. Consequently, the creation of thermally comfortable microclimates in urban environments is highly important. The main aim of this thesis is to dee
BACKGROUND: Spatial epidemiological analyses primarily depend on spatially-indexed medical records. Some countries have devised ways of capturing patient-specific spatial details using ZIP codes, postcodes or personal numbers, which are geocoded. However, for most resource-constrained African countries, the absence of a means to capture patient resident location as well as inexistence of spatial d
OBJECTIVES: Educating healthcare professionals in patient safety is essential to achieving sustainable improvements in care. This study aimed to identify the key constituents of patient safety education alongside its facilitators and barriers from a frontline perspective.METHODS: An electronic survey was sent to 592 healthcare professionals and educators in patient safety education in the United K
Flexible and powerful control over network flows is one of the core advantages of Software-Defined Networking (SDN). Flow rules stored in switch network flow tables contain information on packet processing and routing. Flow rules are stored in memory, in a set of data structure rules, and managed by a classifier in flow tables. Network flows are a valuable asset: they contain information about the
MicroRNAs (miRNA) play an important role in various biological process by regulating gene expression. Their abnormal expression may lead to cancer. Therefore, analysis of such data may discover potential biological insight for cancer diagnosis. In this regard, recently many feature selection methods have been developed to identify such miRNAs. These methods have their own merits and demerits as th
Site-specific land management practice taking into account variability in maize yield gaps (the difference between yields in the 90th percentiles and other yields on smallholder farmers’ fields) could improve resource use efficiency and enhance yields. However, the applicability of the practice is constrained by inability to identify patterns of resource utilization to target application of resour
Whole-genome sequencing projects are increasingly populating the tree of life and characterizing biodiversity1–4. Sparse taxon sampling has previously been proposed to confound phylogenetic inference5, and captures only a fraction of the genomic diversity. Here we report a substantial step towards the dense representation of avian phylogenetic and molecular diversity, by analysing 363 genomes from
HQC is an IND-CCA2 KEM running for standardization in NIST’s post-quantum cryptography project and has advanced to the second round. It is a code-based scheme in the class of public key encryptions, with given sets of parameters spanning NIST security strength 1, 3 and 5, corresponding to 128, 192 and 256 bits of classic security.In this paper we present an attack recovering the secret key of an H
