A bstract We propose a second renormalization group (SRG) in the triad representation of tensor networks. The SRG method improves two parts group, which are decomposition intermediate tensors and preparation isometries, taking influence environment into account. Every fundamental including is given as rank-3 tensor, computational cost proposed algorithm scales with $$ \mathcal{O} <mml:math xmln...
A series of brominated mono-methano[60]fullerene malonate derivatives (two diads and one triad) are investigated for intramolecular and external heavy-atom effects on their fluorescence. Significant internal and external heavy-atom effects are observed in the three cases. It is shown that the internal effect doubles when going from the diads to the triad. In bromobenzene and in iodobenzene, the...
A large number of sequences in each newly sequenced genome correspond to lineage and species-specific proteins, also known as ORFans. Amongst these ORFans, a large number are sequences with unknown structures and functions. We have identified a family of sequences, annotated as hypothetical proteins, which are specific to Bacillus and have carried out a computational study aimed at characterizi...
BACKGROUND The Currarino triad is a rare hereditary syndrome comprising anorectal malformation, sacral bony defect, and presacral mass. Most of the patients are diagnosed during infancy. CASE PRESENTATION A 44-year-old man was diagnosed with Currarino triad, with a huge presacral teratoma and meningocele. One-stage surgery via posterior approach was successful. CONCLUSIONS Treatment of the ...
The structure of the junction between sarcoplasmic reticulum (SR) and transverse tubular (T) system at the triad has been studied in twitch fibers of the frog. The junction is formed by flattened surfaces of the SR lateral sacs and the T-system tubule, which face each other at a distance of 120-140 A. At periodic intervals of about 300 A, the SR membrane forms small projections, whose tips are ...
Polymorphous light eruption (PMLE) is an idiopathic photodermatosis elicited by UV radiation (UVR). The objective of this double-blind, randomized, controlled, intraindividual, bilateral comparison was to determine the efficacy of the UVA filters (ecamsule, avobenzone) present in the new sun protection factor (SPF) 40 sunscreen cream in preventing PMLE in maximized outdoor conditions (ie, exagg...
