Regional CBF (rCBF) and regional cerebral blood volume (rCBV) were evaluated by N,N,N'-trimethyl-N'-(2)-hydroxy-3-methyl-5-[123I]iodobenzyl-1, 3-propanediamine-2 HCl- and 99mTC-labeled red blood cells, respectively, and single-photon emission computerized tomography (SPECT) in a patient with focal cerebral ischemia. Sequential transmission computerized tomography (TCT) and SPECT functional data...

PURPOSE To investigate the expression of FAS ligand (FASL) in ipsilateral and contralateral testicles of rats submitted to ischemia/reperfusion. METHODS Wistar rats (n=21) distributed into groups control (GC), n=5, testicular exposure; ischemia (GI), (n=8), Torsion in the left testicular Cord (TCT) for three hours followed by orchiectomy without distortion and orchietomy of the contralateral ...

The microbump (μ-bump) reliability of 3D integrated circuit (3D-IC) packaging must be enhanced, in consideration of the multi-chip assembly, during temperature cycling tests (TCT). This research proposes vehicle fabrications, experimental implements, and a nonlinear finite element analysis to systematically investigate the assembled packaging architecture that stacks four thin chips through the...

In this paper, a new method is proposed for estimating the depreciation rate of technological knowledge based on the analysis of technology cycle time (TCT). Patent citation data are used in an empirical analysis. The following features characterize the proposed TCT-based method: i) Estimation of the depreciation rate is measured by using the entire set of patents; and ii) The current approach ...

We have irradiated Czochralski silicon (Cz-Si) and Float Zone silicon (Fz-Si) detectors with 24GeV=c and 10MeV protons. Samples were characterized with Capacitance-Voltage measurements (CV), Transient Current Technique (TCT) and secondary electron backscattering recorded by Scanning Electron Microscope (SEM). We present the evolution of the effective doping concentration as a function of irradi...

Social Network Sites (SNSs) are a success story by example. User counts as well as page visits have rocketed in recent years. In this paper we propose to utilize Transaction Cost Theory (TCT) and Social Capital Theory (SCT) to make sense of what kind of social interaction is executed on SNSs and why. In doing so we will show how TCT can be applied to SNSs by proposing to include in the theory t...

At the proximal part of mouse chromosome 17 there are three well-defined genes affecting the axis of the embryo and consequently tail length: Brachyury, Brachyury the second, and the t-complex tail interaction (T1, T2, and tct). The existence of T1 and tct in fact defines the classical "t-complex" that occupies approximately 40 cM of mouse chromosome 17. Their relationship to each other and var...

This study addresses the theoretically neglected role of information system (IS) specificity for application governance, by referring to the allocation of applicationrelated decision authority and task responsibility between business and IT units. Based on the premise of organizational and technical ‘embedding’, and employing a transaction cost theoretic (TCT) lens, we develop the idea that cus...

Culture extracts from the cave-derived actinomycete Nonomuraea specus were investigated, resulting in the discovery of a new S-bridged pyronaphthoquinone dimer and its monomeric progenitors designated hypogeamicins A-D (1-4). The structures were elucidated using NMR spectroscopy, and the relative stereochemistries of the pyrans were inferred using NOE and comparison to previously reported compo...

In recent years, researchers have tried to estimate the direction-of-arrival (DOA) of wideband sources and several novel techniques been proposed. this paper, we compare six algorithms for calculating DOA broadband signals, namely coherent subspace signal method (CSSM), two-sided correlation transformation (TCT), incoherent multiple classification (IMUSIC), test orthogonality frequency subspace...
