Two results are presented on a SVD-like decomposition of 4th-order tensors. This is motivated by an array processing problem: consider an array of m sensors listening at n independent narrow band sources; the 4th-order cumulants of the array output form a 4th-order rank-deecient symmetric tensor which has a tetradic structure. Finding a tetradic decomposition of this tensor is equivalent to ide...

Age estimation of unknown skeletal remains is very important in forensic medicine. Morphologic methods are fast and easy to use for purpose of age determination. The sternal ends of the ribs are a reliable method of age estimation from late adolescence to old age. Iscan et al developed a phase analysis method for the right 4th rib that was sex and race specific. The purpose of this study is to ...

BACKGROUND In liver injury, the pool of hepatic stellate cell (HSC) increases and produces extracellular matrix proteins, decreasing during the resolution of fibrosis. The profibrogenic role of endothelin-1 (ET-1) in liver fibrosis remains disputed. We therefore studied the effect of ET-1 on proliferation, apoptosis and profibrogenic gene expression of HSCs. RESULTS First passage HSC predomin...

A leptonic (l̄l) decay of a heavy quark-antiquark bound state T (Q̄Q) with a Higgs-boson H emission is investigated. The applying of the well-known low-energy theorem to meson-Higgs coupling allows one to estimate the probability of the decay T (Q̄Q) → l̄lH. The only a simple version of the Standard Model extension containing two-Higgs doublet is considered. It is well-known that some extensions of...

The requirement of retinoic acid (RA) in the initial formation of the pharyngeal arches was investigated by treating headfold-stage mouse embryos with a pan-RAR antagonist in vitro and in vivo. This results in a complete absence of mesenchyme, arteries, nerves and epibranchial placodes of the 3rd and 4th pharyngeal arches, complete agenesis of the 3rd and 4th pouches and consistent lack of the ...

OBJECTIVE The aim of this study was to assess the antibody response to combined passive-active immunization versus active immunization against hepatitis B in 71 patients with acute leukemia with negative hepatitis B virus serology at presentation. METHODS The first group (n=28) received a double dose of hepatitis B vaccine at 0, 1, 2 and 6 months and immunoglobin (HBIG) at 0 and 1 month concu...

Although the addition of 2nd and 4th order artiicial viscosity terms to cell vertex discretisations is standard practice, it is widely recognised that there is a lack of understanding of their exact function. This report explores the need for, and the function of, both 2nd and 4th order artiicial viscosity models, and presents improved designs.

Male and female adults of Culex (Culex) articularis Philippi are redescribed, and the 4th-instar larva and pupa are described and illustrated for the first time. Culex articularis is compared with other species of the subgenus Culex. Illustrations of diagnostic characters of the female, male genitalia, 4th-instar larva, and pupa are also provided.
