Objective: Endoscopic Submucosal Dissection (ESD) can be used to resect gastrointestinal diseases, but ESD costs long procedure time. It was reported that the rulers can serve as an ancillary device for shortening the procedure time. Thus, we aimed to identify a ruler assisted method performed by endoscopic nurses to shorten ESD procedure time and improve safety. Methods: A total of 30 patients...

Sik,?On the 26th of May I had occasion to perform an amputation at the shoulder joint for osteo-myelitis of the humerus of 10 years' standing. The coracoid process of the scapula was carious, and part of it required removal. During theoperation the axillary artery was compressed by simply pressing one end of the office ruler, which was about an inch in diameter, into the axilla. The end of the ...

A novel channel allocation method, based on optimal golomb ruler, that allows reduction of FWM effect while maintaining bandwidth efficiency, is presented. Simulation is carried out to show performance improvement in WDM systems without inducing bandwidth increase.

[Purpose] Postural problems of adolescents needs to be evaluated accurately because they may lead to greater problems in the musculoskeletal system as they develop. Although photographic posture analysis has been frequently used, more simple and accessible methods are still needed. The purpose of this study was to investigate the inter- and intra-rater reliability of photographic posture analys...

An actin ruler n page 947, McElhinny et al. suggest that nebulin is a molecular ruler for actin filaments in muscle cells. Muscle physiology depends on the precise alignment, length, and overlap of thin (actin) and thick (myosin) filaments. Capping proteins such as Tmod stop the growing and shrinking of dynamic thin filaments but lack the innate ability to know when to do so. The new results sh...

The authors compared 3 measures of readiness to change alcohol use commonly used in clinical research and practice with adolescents: the Readiness Ruler, the SOCRATES (subscales of Recognition and Taking Steps), and a Staging Algorithm. The analysis sample consisted of 161 male and female adolescents presenting for intensive outpatient alcohol-abuse treatment who reported current alcohol use at...

Size varies. Small things are typically more frequent than large things. The logarithm of frequency often declines linearly with the logarithm of size. That power law relation forms one of the common patterns of nature. Why does the complexity of nature reduce to such a simple pattern? Why do things as different as tree size and enzyme rate follow similarly simple patterns? Here I analyze such ...

We measure the length of the baryon acoustic oscillation (BAO) feature, and the expansion rate of the recent Universe, from low-redshift data only, almost model independently. We make only the following minimal assumptions: homogeneity and isotropy, a metric theory of gravity, a smooth expansion history, and the existence of standard candles (supernovæ) and a standard BAO ruler. The rest is det...

The research presented in this paper is situated in the framework of constraint databases that was introduced by Kanellakis, Kuper, and Revesz in their seminal paper of 1990. Constraint databases and query languages are defined using real polynomial constraints. As a consequence of a classical result by Tarski, first-order queries in the constraint database model are effectively computable, and...

Celem niniejszego artykułu jest rzucenie nowego światła na rolę postaci męskich w średniowiecznej literaturze arabskiej.
