Denote the total domination number of a graph G by γt(G). A graph G is said to be total domination edge critical, or simply γtcritical, if γt(G + e) < γt(G) for each edge e ∈ E(G). For 3t-critical graphs G, that is, γt-critical graphs with γt(G) = 3, the diameter of G is either 2 or 3. We characterise the 3t-critical graphs G with diam G = 3.

Three-terminal (3T) and four-terminal (4T) tandem photovoltaic (PV) devices using various materials have been increasingly reported in the literature, but measurement standards are lacking. Here, multiterminal measured as functions of two load variables characterized unambiguously three device voltages or currents on hexagonal plots. We demonstrate these techniques GaInP/GaAs solar cells, with ...

The inherent doubling in signal-to-noise ratio when compared to 1.5T provides unique opportunities for body MR imaging at 3T. The augmented SNR can be used to improve anatomic and/or temporal resolution and reduce breath hold time periods while preserving image quality. However, susceptibility, and chemical shift dispersion are also increased at 3.0T (scaling with field strength) and T1 and T2 ...

Three strains of prosthecate, budding bacteria, MHS-2T, MHS-3T and VP6T, were isolated from marine habitats including the open ocean (the pelagic zone), the offshore region (the neritic zone) and the hydrothermal vent region. A polyphasic approach including 16S rDNA sequencing, phenotypic analyses, serology, fatty acid analyses, membrane protein profiles and DNA-DNA hybridizations was used to p...

A Multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, Digital Signal Processors (DSPs), Microprocessors etc., A Wallace tree multiplier is an improved version of tree based multiplier architecture. It uses 4:2, 5:2 compressors and a Carry Select Adder (CSA) to reduce the latency and power consumption. In conventional methods, 10T XNOR s...

A programmable CSF shunt valve was assessed for magnetic field interactions, heating (transmit-receive body radio-frequency coil; whole-body averaged specific absorption rate, 2.1 W/kg), functional alterations, and artifacts at 3T. The programmable valve showed minor magnetic field interactions and heating was not excessive (+0.8 degrees C). The function of the programmable valve was not altere...

Background: Talar chondral defects can be a source of persistent ankle pain and disability. If untreated, there is an increased risk of osteoarthritis. The purpose of our study was to determine diagnostic accuracy of 3T MRI in detecting Outerbridge grades 3 and 4 articular cartilage lesions of the talus in a clinical setting, utilizing a standardized clinical MRI protocol. Methods: Patients who...

BACKGROUND AND PURPOSE With appropriate selection, temporal lobe epilepsy is potentially curable with surgical intervention achieving seizure freedom in ~80% of individuals. MR imaging-based identification of MTS remains central to the selection process but currently relies on qualitative visual analysis. We sought to determine if new ultrastructural hippocampal details seen on 3T MR imaging ha...

Two new 3T MR imaging contrast methods, track density imaging and echo modulation curve T2 mapping, were combined with simultaneous multisection acquisition to reveal exquisite anatomic detail at 7 canonical levels of the brain stem. Compared with conventional MR imaging contrasts, many individual brain stem tracts and nuclear groups were directly visualized for the first time at 3T. This new a...
