Reinforced concrete (RC) slabs exhibit complexities in their structural behavior under load due to the composite nature of the material and the multitude and variety of factors that affect such behavior. Current methods for determining the load-deflection behavior of reinforced concrete slabs are limited in scope and are mostly dependable on the results of experimental tests. In this study, an ...

Nanosecond transient absorption spectroscopy has been used to study reaction centre (RC) chlorophyll triplet quenching by carotenoid in intact photosystem II cores from T. elongatus with closed RCs. We found a triplet beta-carotene ((3)Car) signal (absorption difference maximum at 530 nm) that is sensitized by the RC chlorophyll (Chl) triplet with a formation time of ca. 190 ns, has a decay tim...

In this paper we generalize the framework of the feasible descent method (FDM) to a randomized (R-FDM) and a coordinate-wise random feasible descent method (RC-FDM) framework. We show that the famous SDCA algorithm for optimizing the SVM dual problem, or the stochastic coordinate descent method for the LASSO problem, fits into the framework of RC-FDM. We prove linear convergence for both R-FDM ...

The phototrophic bacterium Rhodobacter capsulatus contains a single, oxygen-responsive superoxide dismutase (SOD(Rc)) homologous to iron-containing superoxide dismutase enzymes. Recombinant SOD(Rc), however, displayed higher activity after refolding with Mn(2+), especially when the pH of the assay mixture was raised. SOD(Rc) isolated from Rhodobacter cells also preferentially contains manganese...

We describe the use of appropriate type simple resistor and capacitor (RC) compensators, which properly connected to a power amplifier, can improve the dynamic performance of MEMS (Microelectromechanical Systems) nanopositioners. Research on compensators led to the design of several simple RC compensators that may be appropriate for the NIST symmetric dual parallel lever nanopositioner. Using b...

Background: To study if patients that have a second radiograph 2 or more years after nonoperative treatment of an isolated radial head fracture have radiocapitellar osteoarthritis (RC OA). Methods: We used the database of 3 academic hospitals in one health system from 1988 to 2013 to find patients with isolated radial head fractures (no associated ligament injury or fracture) that had a second ...

Mitochondrial DNA (mtDNA) mutations are a cause of human disease and are proposed to have a role in human aging. Clonally expanded mtDNA point mutations have been detected in replicating tissues and have been shown to cause respiratory chain (RC) defects. The effect of these mutations on other cellular functions has not been established. Here, we investigate the consequences of RC deficiency on...

In Mandarin Chinese there are two possibilities with regard to the relative order of relative clauses (RC) and demonstrative expressions (DM). A relative clause may either precede a demonstrative expression (RC+DM) or follow it (DM+RC). Traditionally, it is assumed that the latter is transformationally derived from the former by virtue of the movement of DM across RC. An investigation of a larg...

The rainbow connection number, rc(G), of a connected graph G is the minimum number of colors needed to color its edges, so that every pair of vertices is connected by at least one path in which no two edges are colored the same. Our main result is that rc(G) ≤ dn2 e for any 2-connected graph with at least three vertices. We conjecture that rc(G) ≤ n/κ + C for a κ-connected graph G of order n, w...

Neoadjuvant cisplatin-based chemotherapy for muscle-invasive bladder cancer (MIBC) is more beneficial for clinical T3/4 than clinical T2 (cT2) disease. The aim of this study was to assess whether neoadjuvant GCarbo has a survival impact on cT2 bladder cancer. We retrospectively reviewed the medical records of 363 consecutive patients who underwent radical cystectomy (RC) between April 1997 and ...
