background: selective alveolar corticotomy is defined as an intentional injury to cortical bone. this technique is an effective means of accelerating orthodontic tooth movement. the aim of this study is to evaluate the effect of buccal corticotomy in accelerating maxillary canine retraction. materials and methods: the sample in this clinical trial study consisted of 15 adult female patients wit...

The main effects which limit accelerating gradient in CLIC (Compact Linear Collider) main linac accelerating structures are RF breakdown and pulsed surface heating. Recent highlights of the structure development program are presented, including demonstration of higher accelerating gradients using tungsten and a complete redesign of the CLIC main linac accelerating structure, based on reduced su...

We demonstrate that any two-dimensional accelerating beam can be described in a canonical form in Fourier space. In particular, we demonstrate that there is a one-to-one correspondence between complex functions in the real line (the line spectrum) and accelerating beams. An arbitrary line spectrum can be used to generate novel accelerating beams with diverse transverse shapes. The line spectra ...

During the last SPARC run a preliminary experimental study of the velocity bunching technique has been performed. Bunch length and projected emittance have been measured at the linac exit as a function of the injection phase in the first accelerating structure and for different solenoids field values. A maximum compression ratio up to a factor 13 has been observed. In particular a peak current ...

Receptor binding and subsequent cell-mediated internalization or disassembly are the initial steps in virus replication. Cell surface molecules that participate in this process are the primary determinants of virus tissue tropism. Monoclonal antibody blockade, immunoprecipitation, and DNA transfection were used to identify decay accelerating factor as a major cell attachment receptor for coxsac...

Explain the Role of Psychological Capital in Knowledge Sharing of an Organization Abstract The aim of present study was to investigate knowledge sharing approach as essential factor in the advancement of organization's purposes and also the effect of psychological capital dimensions in improving and accelerating of this process and want to measure these effects in transferring knowledge among i...

The conversion of plasma to serum results in a variable loss of the coagulase-reacting factor (C.R.F.) of the plasma. The C.R.F. loss is incurred during the process of prothrombin conversion: conditions which favor the most effective prothrombin conversion result in maximal C.R.F. loss, while factors which interfere with prothrombin conversion spare the C.R.F. In a system containing an adequate...

A new accelerated algorithm to solve the single-facility minisum location problem is developed. The acceleration is achieved using a feedback factor. The proposed algorithm converges faster than the accelerating procedures available in the literature. Being nearly as simple as the classical Weiszfeld procedure, the new method can easily be implemented in real applications. Practical subroutines...

Infections caused by Escherichia coli isolates expressing adhesins of the Dr family are associated with diarrhea and urinary tract infections, and these E. coli strains recognize the complement regulatory protein decay-accelerating factor (DAF) as their receptor. Clustering of the DAF receptor at the sites of bacterial adherence to epithelial cells is proposed as an alternative to PCR assay for...

We theoretically and numerically investigate the nonparaxial self-accelerating beams in a Λ-type three-level energy system of rubidium atomic vapor in the electromagnetically induced transparency (EIT) window. In the EIT window, the absorption of the atomic vapor is small, and robust nonparaxial self-accelerating beams can be generated. The reason is that the energy of the tail transfers to the...
