The Effect of Admission at Weekends on Clinical Outcomes in Patients with Non-ST-segment Elevation Acute Coronary Syndrome and Its Contributing Factors

We investigated the effects of weekend admission on adverse cardiac events in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Patients with NSTE-ACS treated with percutaneous coronary intervention (PCI) were divided into a "weekend group" and a "weekday group" according to the emergency room arrival time. The primary outcome was 30-day major adverse cardiac events (MACE) including cardiac death, recurrent myocardial infarction, repeat revascularization, and urgent PCI. Of 577 patients, 168 patients were allocated to the weekend and 409 patients to the weekday group. The incidence of 30-day MACE was significantly higher in the weekend group (Crude: 15.5% vs. 7.3%, P = 0.005; propensity score matched: 12.8% vs. 4.8%, P = 0.041). After adjustment for all the possible confounding factors, in Cox proportional hazard regression analysis, weekend admission was associated with a 2.1-fold increased hazard for MACE (HR, 2.13; 95% CI, 1.26-3.60, P = 0.005). These findings indicate that weekend admission of patients with NSTE-ACS is associated with an increase in 30-day adverse cardiac event. Graphical Abstract
Interpreters – experts in careful listening and efficient encoding? Findings of a prose recall test

Research Questions: The purpose of the present experiment was to study interpreters’ recall of spoken prose. Design: The prose recall of simultaneous and consecutive interpreters was compared to that of foreign language teachers and non-linguistic experts. The professional experience of participants (21–24 participants in each group) was 10 years as a aminimum. The auditory presentation of the prose passage to be recalled, divided into eleven speech sequences, resembled the working conditions of interpreters. Data: Transcripted prose recall recordings were analysed quantitatively through an idea unit measure and qualitatively through meaning-based expressions. Findings: The foreign language expert groups outperformed the non-linguistic experts in both quantitative and qualitative measures. Additionally, compared to foreign language teachers, interpreters indicated a better recall of time expressions and topic sentences, as well as of complicated emotional and causal expressions. The explanation for these findings could indicate expertise-dependent tendencies: possibly a continuous practising of careful listening and the demand for a quick comprehension of the source text under the extreme time pressure of interpreters’ work leads to better results in prose recall. However, the findings can only be generalized to a limited extent because the prose passage used contained only one or two expressions of each type studied in the qualitative analysis. Originality: The study differs from previous studies in that the memory of interpreters, and especially of consecutive interpreters, was studied for the first time with a prose recall measure. Significance: The prose recall test revealed that the abilities of careful listening and effective comprehension of coherence and causality seem to play a significant role in explaining memory functions of simultaneous and consecutive interpreters compared to those of foreign language teachers and non-linguistic experts.
Varactor-tuned combline bandpass filter using step-impedance microstrip lines

In this paper, a varactor-tuned combline bandpass filter using step-impedance microstrip lines is considered so that the absolute passband bandwidth can be maintained nearly constant within the tuning range. The difference between the odd- and even-mode characteristics of the coupled microstrip line makes it difficult to design a tunable bandpass filter with minimum degradation in passband performance. By using step-impedance microstrip lines, couplings between resonators can be controlled so that the constant bandwidth requirement could be satisfied with reasonable design parameter values. Lumped inductors are used for input and output coupling networks. Design equations are derived, and experimental results are compared with theoretical ones based on these equations.

Noninvasive assessment of autonomic function in human neonates born at the extremes of fetal growth spectrum

Birth weight is associated with adult cardiovascular disease, such that those at both ends of the spectrum are at increased risk. This may be driven in part by modification to autonomic control, a mechanistic contributor to hypertension. However, birth weight is a relatively crude surrogate of fetal growth; and newborn body composition may more accurately identify the “at risk” infant. Accordingly, we sought to determine whether newborns with high or low body fat have altered autonomic control of vasomotor function and cardiac contractility. Body fat was assessed by air‐displacement plethysmography <24 h postnatal. Measures of spontaneous baroreflex sensitivity (sBRS), blood pressure variability (BPV), and dP/dtmax variability were compared between newborns categorized according to established body fat percentiles: high body fat (HBF, >90th percentile, n = 7), low body fat (LBF, ≤10th percentile, n = 12), and normal body fat (control, >25th to ≤75th percentile, n = 23). BPV was similar across body fat percentiles; similarly, low frequency dP/dtmax variability was similar across body fat percentiles. sBRS was reduced in HBF compared to controls (11.0 ± 6.0 vs. 20.1 ± 9.4 msec/mmHg, P = 0.03), but LBF did not differ (18.4 ± 6.0 msec/mmHg, P = 0.80). Across the entire body fat spectrum (n = 62), there was a nonlinear association between newborn body fat and sBRS (P = 0.03) that was independent of birth weight (P = 0.04). Autonomic modulation of vasomotor function and cardiac contractility in the newborn did not differ by body fat, but newborns born with high body fat show depressed baroreflex sensitivity.

Learning Prototypes for On-Line Handwritten Digits

A writer independent handwriting recognition system must be able to recognize a wide variety of handwriting styles, while attempting to obtain a high degree of accuracy when recognizing data from any one of those styles. As the number of writing styles increases, so does the variability of the data’s distribution. We then have an optimization problem: how to best model the data, while keeping the representation as simple as possible? If we can identify N different styles of writing individual characters (referred to as lexemes), these can then be modeled as N relatively simple independent distributions. We describe here a template-based system using a string-matching distance measure for the recognition of on-line handwriting which takes advantage of lexemes to reduce the number of templates that must be stored. A method of identifying lexemes and lexeme representatives is shown, and experimental results are given for a set of handwritten digits taken from 21 different writers. The use of lexeme representatives reduces classification time by 90.2% while retaining approximately 98% of the recognition accuracy.
A Longitudinal Analysis of the Network Complexity of the World Trade Web

The increasingly broad global connectivity of international trade is just one general way in which the patterns and partners of trading have evolved over the past decades. In this paper we use techniques related to modern network analysis to investigate and quantify the evolution of what is known as “The World Trade Web” (WTW). WTW analysis uses the directed and weighted networks of yearly country-to-country imports and exports in real dollars. To these networks we apply different tools in order to articulate the structure of individual networks (i.e., a given year’s statistics) as well as the evolution of structure over time (1948-2000, and 2005). We analyze the dynamics of network centrality and community structure in the WTW. With respect to centrality, we utilize tools from the web-search domain, specifically, the concepts of authorities and hubs. The most novel part of our work is related to the evolution of communities in the world trade web through the consideration of a newly developed notion of “cluster persistence. ” The persistence of a cluster quantifies the degree to which a cluster remains intact as the network evolves. By tracking cluster persistence we provide an account of the evolution of community structure of the WTW. We also track the movement of countries between clusters, cluster composition, as well as the frequency of movement. In total, these kinds of
Identification of Amino Acid Residues in the α, β, and γ Subunits of the Epithelial Sodium Channel (ENaC) Involved in Amiloride Block and Ion Permeation

The amiloride-sensitive epithelial Nachannel (ENaC) is a heteromultimeric channel made of three αβγ subunits. The structures involved in the ion permeation pathway have only been partially identified, and the respective contributions of each subunit in the formation of the conduction pore has not yet been established. Using a site-directed mutagenesis approach, we have identified in a short segment preceding the second membrane-spanning domain (the pre-M2 segment) amino acid residues involved in ion permeation and critical for channel block by amiloride. Cys substitutions of Gly residues in β and γ subunits at position βG525 and γG537 increased the apparent inhibitory constant (K i) for amiloride by >1,000-fold and decreased channel unitary current without affecting ion selectivity. The corresponding mutation S583 to C in the α subunit increased amiloride K i by 20-fold, without changing channel conducting properties. Coexpression of these mutated αβγ subunits resulted in a nonconducting channel expressed at the cell surface. Finally, these Cys substitutions increased channel affinity for block by externalZn2+ ions, in particular the αS583C mutant showing a K i for Zn2+of 29 μM. Mutations of residues αW582L or βG522D also increased amiloride K i, the later mutation generating a Ca2+blocking site located 15% within the membrane electric field. These experiments provide strong evidence that αβγ ENaCs are pore-forming subunits involved in ion permeation through the channel. The pre-M2 segment of αβγ subunits may form a pore loop structure at the extracellular face of the channel, where amiloride binds within the channel lumen. We propose that amiloride interacts with Na+ions at an external Na+binding site preventing ion permeation through the channel pore.
Cellular Interference Alignment: Omni-Directional Antennas and Asymmetric Configurations

Although interference alignment (IA) can theoretically achieve the optimal degrees of freedom (DoFs) in the K-user Gaussian interference channel, its direct application comes at the prohibitive cost of precoding over exponentially many signaling dimensions. On the other hand, it is known that practical one-shot IA precoding (i.e., linear schemes without symbol expansion) provides a vanishing DoFs gain in large fully connected networks with generic channel coefficients. In our previous work, we introduced the concept of cellular IA for a network topology induced by hexagonal cells with sectors and nearest-neighbor interference. Assuming that neighboring sectors can exchange decoded messages (and not received signal samples) in the uplink, we showed that linear one-shot IA precoding over M transmit/ receive antennas can achieve the optimal M/2 DoFs per user. In this paper, we extend this framework to networks with omnidirectional (non-sectorized) cells and consider a limited practical scenario where users have 2 antennas, and base-stations have 2, 3, or 4 antennas. We provide linear one-shot IA schemes for the 2 × 2, 2 × 3, and 2 × 4 cases, and show the achievability of 3/4, 1, and 7/6 DoFs per user, respectively. DoFs converses for one-shot schemes require the solution of a discrete optimization problem over a number of variables that grows with the network size. We develop a new approach to transform such optimization problem into a tractable linear program with significantly fewer variables. This approach is used to show that 3/4 DoFs per user are indeed optimal for one-shot schemes over large (extended) cellular network with 2 × 2 links.
Multiuser OFDM-MIMO Effect with Fair Resource Allocation in Actual Indoor Multipath Environment

In this paper we evaluate the measured Multi-user MIMO effect with fair resource allocation by using a MU-MIMO testbed, which can evaluate 8 ×8 MIMO channel in an indoor multipath environment. MU-MIMO systems have attracted attention as a technology for increasing the total system capacity. However, unlike single user MIMO (SU-MIMO) systems, multiple receivers cannot cooperate with each other. Thus, the transmit beamforming method at the access point should be designed to cope with interference among multiple spatial channels. Although several approaches to beamforming have been proposed for MU-MIMO systems depending on the degree of awareness of fairness among multiple mobile stations, we focus on a fair resource allocation approach that evenly assigns transmission time to each terminal in order to support terminal diversity better. Although most papers discuss the MU-MIMO effect based on computer simulations or theoretical analysis, only a few measured results have been presented. In this paper, the numbers of users and antennas at the mobile station suitable for MU-MIMO with fair resource allocation are discussed. keywords:Multi-user MIMO, Single-user MIMO, transmit beamforming, Fair resource allocation, indoor multipath
Theorising Urban Playscapes: Producing, Regulating and Consuming Youthful Nightlife City Spaces

This article develops a theoretical understanding of the relationship between young people and city space. More specifically, our focus concerns what we have termed 'urban playscapes'—young people's activities in bars, pubs, night-clubs and music venues within the night-time entertainment economy. The paper theoretically and empirically explores three interrelated aspects of these playscapes: production and the increasing role of a small number of large-scale corporate leisure and entertainment operators providing sanitised, 'branded' experiences ; regulation in which the development of urban playscapes can be understood through a night-time entertainment regime based around a modified relationship between state, developers and consumers, including enhanced forms of surveillance and control; and consumption which is characterised by segmentation and differentiation and based around more 'exclusive' and 'up-market' identities. We argue that these three aspects combine to create a dominant mode of 'mainstream' urban nightlife, with 'alternative' and 'residual' nightlife increasingly under threat or squeezed out. In conclusion, we discuss some of the interrelationships between production, regulation and consumption and suggest a number of potential future scenarios for nightlife development.

Structural DMR: A Technique for Implementation of Soft-Error-Tolerant FIR Filters

In this brief, an efficient technique for implementation of soft-error-tolerant finite impulse response (FIR) filters is presented. The proposed technique uses two implementations of the basic filter with different structures operating in parallel. A soft error occurring in either filter causes the outputs of the filters to differ, or mismatch, for at least one sample. The filters are specifically designed so that, when a soft error occurs, they produce distinct error patterns at the filter output. An error detection circuit monitors the basic filter outputs and identifies any mismatches. An error correction circuit determines which filter is in error based on the mismatch pattern and selects the error-free filter result as the output of the overall error-protected system. This technique is referred to as structural dual modular redundancy (DMR) since it enhances traditional DMR to provide error correction, as well as error detection, by means of filter modules with different structures. The proposed technique has been implemented and evaluated. The system achieves a soft error correction rate of close to 100% for isolated single soft errors and has a logic complexity significantly less than that of conventional triple modular redundancy.
Rejection positivity predicts trial-to-trial reaction times in an auditory selective attention task: a computational analysis of inhibitory control

A series of computer simulations using variants of a formal model of attention (Melara and Algom, 2003) probed the role of rejection positivity (RP), a slow-wave electroencephalographic (EEG) component, in the inhibitory control of distraction. Behavioral and EEG data were recorded as participants performed auditory selective attention tasks. Simulations that modulated processes of distractor inhibition accounted well for reaction-time (RT) performance, whereas those that modulated target excitation did not. A model that incorporated RP from actual EEG recordings in estimating distractor inhibition was superior in predicting changes in RT as a function of distractor salience across conditions. A model that additionally incorporated momentary fluctuations in EEG as the source of trial-to-trial variation in performance precisely predicted individual RTs within each condition. The results lend support to the linking proposition that RP controls the speed of responding to targets through the inhibitory control of distractors.
Performance study on a WDM packet switch with limited-range wavelength converters

We consider a slotted WDM packet switch with limited-range wavelength converters. The performance of this switch is studied using simulations with various types of data traffic. Results show that the slotted WDM packet switch with a small range of wavelength conversion capability can achieve a performance close to that of a switch with the full range of wavelength conversion capability.
Wavelet-Based Statistical Analysis versus SPM of Brain Imaging Data

Analysis of functional magnetic resonance imaging (fMRI) data of a block-based visual stimulation paradigm was comparatively performed by the discrete wavelet transform (DWT) in the wavelet domain and statistical parametric mapping (SPM) within the framework of the general linear model (GLM) [1]. The link is supported by the low-pass analysis filter of the DWT that can be similarly shaped to a Gaussian filter in SPM and by the subsampling scheme that provides means to define the number of coefficients in the low-pass subband of the wavelet decomposition [2]. Functional data processing in the wavelet domain was carried out by means of two biorthogonal transforms resulting in activation patterns similar to the activation maps obtained in SPM.
RAISE in Perspective

The RAISE [6] Specification Language, RSL, originated as a development from VDM [9] during a five year effort involving several researchers. The purpose was to improve VDM by augmenting it with a module system, a process description language, a formal semantics standard, and tool support. A goal was to keep the language a wide spectrum language including high level specification constructs as well as low level programming constructs, allowing specification and program fragments to be mixed arbitrarily with each other without imposing a linguistically layered language. The effort resulted in a language inspired by, but in many ways different from VDM. A main deviation from VDM is the emphasis on an algebraic specification-style logic where a module consists of a signature and a set of axioms over the names introduced in the signature. Derived forms exist which reflect the classical VDM definitional style. Correspondingly, types can be abstract sorts as in algebraic specifications or they can be defined through type definitions as in VDM using what is normally referred to as a model oriented style. The pure model oriented style usually uses such explicit type definitions and a definitional style for functions. The pure algebraic style uses sorts and more liberal equations with arbitrary terms on the left hand side as well as on the right hand side. In the axiomatic style emphasis is on operations and how they relate to each other. In the model oriented style there is a specific emphasis on type equations. When modeling a problem in VDM, the problem is usually first approached by writing down a set of type definitions using set, list and map type constructors. Operations are subsequently defined referring to the operators allowed on values of these types. The same style is possible in RSL, although the added module system suggests the association
