We present the results of temperature dependence Raman spectra pyrochlore Cd2Os2O7 single crystal in a range 100-270 K. found that, among six observed active modes, 762 cm-1 phonon has significant peak shift and asymmetric Fano lineshape. The temperature-dependent frequency full width at half maximum (FWHM) shows kinks near Néel temperature. complex asymmetry parameter anomalies FWHM below indi...

Traditional circulating biomarkers play a fundamental role in the diagnosis and prognosis of acute myocardial infarction (AMI). However, they have several limitations. microRNAs (miRs), a class of RNA molecules that do not encode proteins, function directly at the RNA level by inhibiting the translation of messenger RNAs. Due to their significant roles in disease development, they can be used a...

When we set out to apply nonlinear techniques, or even techniques inspired by chaos theory, to phenomena occurring in the brain, it seems wise to rst ask if the use of such advanced techniques is justiied by the data. While it seems very unlikely that the brain is a linear apparatus, its nonlinear nature might not be evident in speciic aspects of its dynamics and we might be better oo using the...

Commercial electronic voting systems have experienced many high-profile software, hardware, and usability failures in real elections. While it is tempting to abandon electronic voting altogether, we show how a careful application of distributed systems and cryptographic techniques can yield voting systems that surpass current systems and their analog forebears in trustworthiness and usability. ...

In upper tertiary educational programmes around the world, the new Web-mediated communication practices termed Web 2.0 are introduced as learning activities with the goal of facilitating learning through collaborative knowledge construction. The aim of this paper is to point to discrepancies in the views of learning, knowledge, and the goals of the practice implicit in Web 2.0 and educational p...

Prominent working memory (WM) deficits have been observed in people with schizophrenia (PSZ) across multiple sensory modalities, including the visuospatial realm. Electrophysiological abnormalities noted during early visual processing as well as later cognitive functions in PSZ may underlie deficiencies in WM ability, though the mechanisms linking behavior to neural responses are not well under...

An 81-year-old man with retinitis pigmentosa had severe, slowly progressive visual loss that began at age 20. Intermittent nystagmus was observed for 1 decade. Examination revealed severe retinal atrophy and periodic alternating nystagmus (PAN) that occurred only in darkness (video on the Neurology® Web site at www.neurology.org). PAN refers to horizontal nystagmus that periodically reverses di...

The main study objective was to determine if experienced emergency physicians can accurately identify a subgroup of patients with anterior shoulder dislocation for whom prereduction radiographs do not alter patient management. Our prospective study evaluated 97 patients who presented to 2 ski-hill clinics and to our rural emergency department with possible shoulder dislocation between November ...

Oligosaccharide structures derived from the lipooligosaccharide of M. catarrhalis show that the highly branched glucose-rich inner core of the oligosaccharide has an altered conformation compared to the most truncated tetra-glucose-Kdo lgt1/4Δ oligosaccharide structure. Addition of one residue each to the (1-4) and (1-6) chains to give the lgt2Δ oligosaccharide is the minimum requirement for th...

This paper presents the design, implementation, and evaluation of CATS, a toolkit for indexed state storage for network services. CATS is based on a new implementation of a persistent authenticated dictionary, which integrates signed action records and cryptographic state digests into an index. This storage abstraction enables a CATS-based network service to certify its operations: any client w...
