Starting from the well established form of the Dirac action coupled to the electromagnetic and torsion field we find that there is some additional softly broken local symmetry associated with torsion. This symmetry fixes the form of divergences of the effective action after the spinor fields are integrated out. Then the requirement of renormalizability fixes the torsion field to be equivalent t...

Charged excitons in doped extended Hubbard model systems. Abstract We show that the charge transfer excitons in a Hubbard model system including nearest neighbor Coulomb interactions effectively attain some charge in doped systems and become visible in photoelectron and inverse photoelec-tron spectroscopies. This shows that the description of a doped system by an extended Hubbard model differs ...

Linear support vector machines (SVM) are useful for classifying large-scale sparse data. Problems with sparse features are common in applications such as document classification and natural language processing. In this paper, we propose a novel coordinate descent algorithm for training linear SVM with the L2-loss function. At each step, the proposed method minimizes a one-variable sub-problem w...

| This paper presents a new synthesis procedure (design algorithm) for cellular neural networks with space-invariant cloning template with applications to associative memories. In the present synthesis procedure, the design problem is formulated as a set of linear inequalities and the inequalities are solved using the well-known percep-tron training algorithm. When desired memory patterns are g...

| This paper proposes a general model for bidi-rectional associative memories that associate patterns between the X-space and the Y-space. The general model does not require the usual assumption that the interconnection weight from a neuron in the X-space to a neuron in the Y-space is the same as the one from the Y-space to the X-space. We start by deening a supporting function to measure how w...

background: leucocytozoonosis is a disease of birds caused by obligate intracellular protozoa of the genus leucocytozoon. we determined the prevalence of leucocytozoon spp. using light and transmis-sion electron microscopy in domestic birds in southwest of iran. methods: a total of 825 blood smears from 275 birds were examined for presence of infection. the structure morphology of leucocytozoon...

BackgroundIn all of randomized controlled trials mechanical thrombectomy, the target vessels were proximal. Herein we report a clinical trial Tron FX stent retriever, including smallest size 2/15 mm for distal intracranial large vessel occlusion (LVO).ObjectiveEligible patients presented within 8 h onset with proximal or LVOs, and 4/20 used as first-line device.MethodsThe primary endpoints rate...

For a long time now, people have known the devastating effects of soil agriculture. This can include deforestation due to excessive agriculture which increases carbon emissions causing global warming. Previous research emphasized urgency developing green sustainable solutions grow food such as hydroponics and aeroponics. Tron Sherman, Mansfield, MO, introduced idea using recyclable substrate (i...

Trust has been identified as the key to e-commerce because it is crucial wherever uncertainty and interdependence exist. The strong association between a high level of trust and the banking sector has not yet been fully translated in the electronic world. The aim of this article is to develop and validate a multi-dimensional model of trust for Internet banking. The data are collected through 44...
