This paper designs an impulse-radio ultrawideband (IR-UWB) system for precise ranging and low-rate communication, especially targeting IEEE 802.15.4a standard, which is a candidate technology for realizing the ubiquitous home. We first introduce the IR-UWB packet and packet based ranging in IEEE 802.15.4a. Incorporated by IR-UWB link budget analysis, we propose a full-digital transceiver along with the corresponding baseband receiver algorithms. We then discuss implementation issues for IR-UWB system, ...

Myocardial ischemia, which precedes acute myocardial infarction (AMI)1 is associated with changes in human serum albumin (HSA) that result in decreased divalent cobalt ion (Co2+) binding. This reaction the basis of the serum colorimetric Co2+-HSA binding assay, which is an indirect measure of ischemia-modified albumin (IMA). Previously we showed that IMA was a useful diagnostic test for the diagnosis of myocardial ischemia in suspected acute coronary syndromes (ACS) patients (area under the ROC curve ...

We developed a fully enzymatic process employing D-hydantoinase and N-carbamoylase for the production of D-amino acid from 5'-monosubstituted hydantoin. For the comparison of the reaction systems using two sequential enzymes, D-hydantoinase of Bacillus stearothermophilus SD1 and N-carbamoyl-D-amino acid amidohydrolase (N-carbamoylase) of Agrobacterium tumefaciens NRRL B11291 were separately expressed in each host cell and coexpressed in the same host cell. A high level and constitutive expression ...

This study examines teacher collaboration across three Asia-Pacific countries (Australia, Malaysia, and South Korea), focusing on the possibility that principal-teacher perceptual disagreement regarding principal instructional leadership performance may impede progress toward a school organizational condition conducive to collaborative teacher interactions. Data for this study were taken from the OECD Teaching and Learning International Survey 2008. Overall, the results from a series of hierarchical ...

Many countries design and implement school change with a focus on the fundamental reconfiguration in the structures of schooling. In this article, we examined the relationship between principal leadership and teacher resistance to school reforms driven by external interveners. For an empirical analysis, we took advantage of extensive data derived from 967 teachers and 32 principals in Korean vocational high schools that are now experiencing school reforms launched by the government. Our results ...

We developed a kinetic model that describes a heterogeneous reaction system consisting of a solid substrate suspension for the production of D-amino acid using D-hydantoinase. As a biocatalyst, mass-produced free and whole cell enzymes were used. The heterogeneous reaction system involves dissolution of a solid substrate, enzymatic conversion of the dissolved D-form substrate, spontaneous racemization of an L-form substrate to D-form, and deactivation of the enzyme. In the case of using whole cell ...

Abstract Open educational resources (OERs) are increasingly adopted in non‐formal education contexts. However, little research has been conducted to investigate the self‐directed learning patterns of non‐formal learners using OERs. A lack of knowledge about non‐formal learners precludes discussions on how to support their self‐regulated learning in open learning environments. We explored the self‐directed learning patterns of 1892 non‐formal online learners who were using OER repositories. In addition, ...

Research shows teacher influence in school decision-making is related to improving individual job satisfaction and professional commitment. However, few empirical studies investigate how different domains of school decision-making may have a distinct relationship with both individual teacher job satisfaction and professional commitment.

Nationally representative data for 8869 teachers in 551 lower secondary schools in England, Finland, South Korea, and the USA were analyzed. In all four countries, a participative school climate was positively associated with teacher collegial interaction, ...

Background S-nitrosation – the formation of S-nitrosothiols (RSNOs) at cysteine residues in proteins – is a posttranslational modification involved in signal transduction and nitric oxide (NO) transport. Recent studies would also suggest the formation of N-nitrosamines (RNNOs) in proteins in vivo, although their biological significance remains obscure. In this study, we characterized a redox-based mechanism by which N-nitroso-tryptophan residues in proteins may be denitrosated. Methodology/Principal Findings ...

Although much literature highlights the importance of teacher expectations for students’ academic success, a very small number of studies used large-scale data to examine school-level factors associated with group-level teacher expectations – defined as expectations that teachers have for many students in their class or school, rather than for a specific student – in the US context. Using contextual data provided by mathematics and science teachers participating in the High School Longitudinal Study ...
