Research-Based Teacher Education Reform: Making Teacher Education Work (2013)

This special issue of Reflecting Education brings together a selection of papers presented at the fifth annual Teacher Education Policy in Europe (TEPE) conference hosted by the University of Vienna in 2011. The initiative to establish the TEPE Network was agreed at the University of Umea (Sweden) in 2006 and the first TEPE meeting was held at the University of Tallinn (Estonia) in 2007 and attended by participants from eight countries. The Network has grown significantly since its inception with the most recent 2012 conference (Warsaw) attracting over 100 participants. Over the course of its six years, the Network has emerged as a leading voice on teacher education policy in Europe, building on the work of previous European collaborative projects in the field of teacher education policy, notably TNTEE and EUDORA. The TEPE Network goals relate to: advancing research in and on teacher education; increasing mobility and extending the European dimension of teacher education; and enhancing quality through the renewal of evaluation cultures in teacher education. Central to its mission is the dissemination of research in the field of teacher education policy.

Abstract We present a fiber sensor based on an active integrated component which could be effectively used to measure the longitudinal vibration modes of telescope mirrors in an interferometric array. We demonstrate the possibility to measure vibrations with frequencies up to ⋍100 Hz with a precision better than 10 nm (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Slow-Injection Growth of Seeded CdSe/CdS Nanorods with Unity Fluorescence Quantum Yield and Complete Shell to Core Energy Transfer (2016)

A two-step process has been developed for growing the shell of CdSe/CdS core/shell nanorods. The method combines an established fast-injection-based step to create the initial elongated shell with a second slow-injection growth that allows for a systematic variation of the shell thickness while maintaining a high degree of monodispersity at the batch level and enhancing the uniformity at the single-nanorod level. The second growth step resulted in nanorods exhibiting a fluorescence quantum yield up to 100% as well as effectively complete energy transfer from the shell to the core. This improvement suggests that the second step is associated with a strong suppression of the nonradiative channels operating both before and after the thermalization of the exciton. This hypothesis is supported by the suppression of a defect band, ubiquitous to CdSe-based nanocrystals after the second growth.
Robust formant features for speaker verification in the lombard effect (2015)

This paper presents a voice controlled speaker verification system for hand-held devices in noisy environments. In noisy environments, users unintentionally increase their voice intensity because of the ear-mouth feedback mechanism i.e., the Lombard effect; thus, the characteristic of the input signal is much different from that in a quiet environment. To enhance the accuracy of a speaker verification system, this paper proposes a robust formant feature that represents the physical nature of the voice production system of the speaker. It utilizes the analysis results that the impact of Lombard varies depending on the types and levels of the background noise, but the third and fourth formant frequencies are insensitive even in the Lombard condition. Experimental results show that optimal performance can be achieved when the above formant frequencies and corresponding bandwidths are combined.
Qualitative Process Automation (1989)

Abstract This paper addresses research in computer science, control theory and material processing science wherein the focus is to develop a process control system which enables in situ process model development. A generic control system architecture employing the use of qualitative physics (QP) is described together with an explanation of the system operation involving multiple co-operating expert systems. Specific details involving development and application of the control system to auotoclave curing of composites is also presented, together with recent research and production results.
Aggregation risk prediction for antibodies and its application to biotherapeutic development (2015)

Aggregation is a common problem affecting biopharmaceutical development that can have a significant effect on the quality of the product, as well as the safety to patients, particularly because of the increased risk of immune reactions. Here, we describe a new high-throughput screening algorithm developed to classify antibody molecules based on their propensity to aggregate. The tool, constructed and validated on experimental aggregation data for over 500 antibodies, is able to discern molecules with a high aggregation propensity as defined by experimental criteria relevant to bioprocessing and manufacturing of these molecules. Furthermore, we show how this tool can be combined with other computational approaches during early drug development to select molecules with reduced risk of aggregation and optimal developability properties.
Crosstalk analysis of high-speed interconnects and packages (2002)

An approach to the crosstalk analysis of high-speed interconnects has been developed. The method yields closed-form expressions of the voltage and current transfer functions and time-domain signal waveforms. The results facilitate analytical evaluation of coupling noise, waveform distortion, and propagation delay due to crosstalk inherent in multiconductor interconnects. The method is applicable to the general problem of N coupled lossy and/or dispersive interconnects with arbitrary linear source/load impedances.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Longitudinal Analysis of Serum Autoantibody-Reactivities in Patients with Primary Open Angle Glaucoma and Optic Disc Hemorrhage (2016)

With this approach we were able to detect autoimmune reactivities in sera of patients with primary open angle glaucoma and optic disc hemorrhage compared to patients without optic disc hemorrhage. These antibodies could give further insights into the pathogenesis and the autoimmune component of glaucomatous optic neuropathy.
Asymmetric Fluorination of α‐Aryl Acetic Acid Derivatives with the Catalytic System NiCl<sub>2</sub>–Binap/R<sub>3</sub>SiOTf/2,6‐Lutidine (2007)

Not binary, but trinary: A binary system consisting of Ni(OTf)2–binap complex and 2,6-lutidine failed to promote the asymmetric fluorination of ester equivalents. However, upon the addition of a substoichiometric amount of Et3SiOTf to the NiCl2–binap/2,6-lutidine catalyst, the monofluorinated products were obtained in good yield with high enantioselectivity (see example). NFSI=N-fluorobenzenesulfonimide, Tf=trifluoromethanesulfonyl.
Parallel convolutional-linear neural network for motor imagery classification (2015)

Deep learning, recently, has been successfully applied to image classification, object recognition and speech recognition. However, the benefits of deep learning and accompanying architectures have been largely unknown for BCI applications. In motor imagery-based BCI, an energy-based feature, typically after spatial filtering, is commonly used for classification. Although this feature corresponds to the estimate of event-related synchronization/desynchronization in the brain, it neglects energy dynamics which may contain valuable discriminative information. Because traditional classiication methods, such as SVM, cannot handle this dynamical property, we proposed an architecture that inputs a dynamic energy representation of EEG data and utilizes convolutional neural networks for classification. By combining this network with a static energy network, we saw a significant increase in performance. We evaluated the proposed method and compared with SVM on a multi-class motor imagery dataset (BCI competition dataset IV-2a). Our method outperforms SVM with static energy features significantly (p < 0.01).
Look-ahead decision-feedback ΣΔ modulation (2002)

We present a novel solution to the problem of instability in multiloop /spl Sigma//spl Delta/ modulators (nonlinear oversampled one-bit A/D and D/A converters). /spl Sigma//spl Delta/ modulators are attractive because their SNR is proportional to their oversampling rate which is physically tied to the speed of the VLSI. The problem of instability in traditional higher order (multiloop) /spl Sigma//spl Delta/ modulators is corrected by a new class of self-stabilizing /spl Sigma//spl Delta/ modulators called look-ahead decision-feedback (LADF) /spl Sigma//spl Delta/ modulators. LADF /spl Sigma//spl Delta/ modulators select the output at each time-step to create the optimally stable set of integrator states at the following time-step. Simulation results for up to third order (triple loop) modulators are included.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<title>High-sensitivity direct detection optical communication system that operates in sunlight</title> (1994)

In freespace laser communication systems, optical background noise rejection is a very important issue. We have designed and built a building to building direct detection optical communication system that uses a Faraday Anomalous Dispersion Optical Filter (FADOF) in the receiver. The FADOF is a narrow bandpass optical filter, which can provide a background noise rejection of 10<SUP>5</SUP> approximately 10<SUP>6</SUP>, while transmitting the signal with up to 80% efficiency. The FADOF also has a signal bandwidth that is variable between 0.5 GHz and 5 GHz, a field-of-view that is flat over +/- 20 degree(s). FADOFs offer new capabilities to freespace laser communication by effectively reducing the solar background radiation that reaches the photodetector. Using the FADOF receiver, we have demonstrated that 27nW of received signal power gives a bit error rate of 10<SUP>-6</SUP> (limited by the photoreceiver electronic noise) independent of solar noise up to 0.15Watt. We also repeated these measurements under the same operation conditions after replacing the FADOF with an interference filter. The experiments showed three orders higher background noise rejection capability for the FADOF receiver.
Content-Aware Resource Allocation for Scalable Video Transmission to Multiple Users Over a Wireless Network (2007)

Wireless video transmission is prone to unpredictable degradations due to time-varying channel conditions. Such degradations are difficult to overcome using conventional video coding techniques. Scalable video coding offers a flexible bitstream that can be dynamically adapted to fit the prevailing channel conditions. Within a scalable video coding framework, we develop simple packet prioritization strategies, which, when combined with a reasonable error concealment scheme and a content-aware resource allocation technique, provide for robust video transmission over time-varying channels. The packet prioritization as well as the calculation of the content-aware scheduling metric can be performed offline and signaled to the wireless scheduler.
A Speculative Coherence Scheme using Decoupling Synchronization for Multiprocessor Systems (2003)

This paper proposes a new speculative coherencescheme, SCDS, for hardware distributed shared memory systemsto reduce the overhead of coherence action in directory-basedcache-coherence protocol. SCDS has two main features,predicting accurate timing of speculative coherence withsynchronization information and detecting write pattern(migratory and non-migratory) for exclusive blocks' speculativecoherence action. In our simulation, SCDS outperforms existingschemes (DSI and LTP) for well-synchronized applications.
An Automatic Prosody Recognizer using a Coupled Multi-Stream Acoustic Model and a Syntactic-Prosodic Language Model (2006)

Automatic detection and labeling of prosodic events in speech has received much attention from speech technologists and linguists ever since the introduction of annotation standards such as ToBI. Since prosody is intricately bound to the semantics of the utterance, recognition of prosodic events is important for spoken language applications such as automatic understanding and translation of speech. Moreover, corpora labeled with prosodic markers are essential for building speech synthesizers that use data-driven approaches to generate natural speech. In this paper, we build a prosody recognition system that detects stress and prosodic boundaries at the word and syllable level in American English using a coupled hidden Markov model (CHMM) to model multiple, asynchronous acoustic feature streams and a syntactic-prosodic model that captures the relationship between the syntax of the utterance and its prosodic structure. Experiments show that the recognizer achieves about 75% agreement on stress labeling and 88% agreement on boundary labeling at the syllable level.
Head injuries in sport. (1996)

Injuries to the head and neck are the most frequent catastrophic sports injury, and head injuries are the most common direct athletic cause of death. Although direct compressive forces may injure the brain, neural tissue is particularly susceptible to injury from shearing stresses, which are most likely to occur when rotational forces are applied to the head. The most common athletic head injury is concussion, which may very widely in severity. Intracranial haemorrhage is the leading cause of head injury death in sports, making rapid initial assessment and appropriate follow up mandatory after a head injury. Diffuse cerebral swelling is another serious condition that may be found in the child or adolescent athlete, and the second impact syndrome is a major concern in adult athletes. Many head injuries in athletes are the result of improper playing techniques and can be reduced by teaching proper skills and enforcing safety promoting rules. Improved conditioning (particularly of the neck), protective headgear, and careful medical supervision of athletes will also minimise this type of injury.
A New Method for Initial Radius Selection of Sphere Decoding (2007)

In this paper, a new initial radius (IR) selection method of Sphere Decoding (SD), called IR-ZF-OSUC, for MIMO system is proposed. An significant merit is that this method utilizes the result ofQR decomposition which is inherent in SD to obtain a suboptimal solution, and selects the distance between the received signal and the lattice point mapped by the suboptimal solution as the IR, which makes the procedure can be embedded in the body of SD. Unlike other approaches, it needs no extra processing, so lower computational complexity is achieved. Additionally, this method includes an ordering step, which not only makes the IR be closer to the optimal value but also increases the efficiency ofSD itself. The simulation results show that the computational complexity ofSD with IR-ZF-OSUC is lower than the ones using other approaches over a wide range ofSNRs.
Design of a Two-Stage AC/DC Converter with Standby Power Losses Less than 1 W (2007)

The objective of this paper is to design and implement an AC/DC converter which meets the green power specification under standby condition. The design of PFC-OFF control and auxiliary circuit which will significantly reduce the standby power to meet the energy code under standby condition will be presented. Moreover, it will be shown that these circuits don't need any current sensor and hysteresis circuit to detect the load condition, which can reduce the cost and avoid false activation caused by current noise. The specifications of converter are as follows: universal input voltage: AC 90-265 V, 50-60 Hz; output voltage: 19V/DC; output power: 250W; standby power: input power < 1 W @ 265 V/AC input. Experimental results have demonstrated that the input power factor is greater than 98% in the whole voltage range and full load condition. The power consumption under standby condition is less than 1 W confirming the design and implementation.

Human Immunodeficiency Virus Infection Among Homeless Men in a New York City Shelter (1990)

• The human immunodeficiency virus (HIV) seroprevalence among a selected sample of 169 high-risk homeless men residing in a congregate shelter in New York City, NY, was 62%. Seropositivity for HIV correlated significantly with intravenous drug use (odds ratio, 3.3; 95% confidence interval, 1.4 to 4.4) and active tuberculosis (odds ratio, 7.0; 95% confidence interval, 3.4 to 13.5). Most cases of active tuberculosis were among homeless men with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex; and significant CD4 lymphocyte depletion was associated with active tuberculosis. Total time homeless correlated positively with active and latent tuberculosis infection. Compliance rates with return for HIV antibody test results, medications, and follow-up visits were 70%, suggesting a significant degree of knowledge, awareness, and personal concern regarding HIV infection among homeless men; yet 28% of homeless intravenous drug users continue active drug injection, despite HIV infection. Cohabitation in overcrowded congregate dormitories creates a risk of airborne transmission of tuberculosis, which is a common reactivation infection in HIV-seropositive homeless men. Medically appropriate housing should be provided to such homeless persons, and expanded HIV antibody testing, counseling, and medical services on site should be offered to residents of shelters.

Slow and fast single photons from a quantum dot interacting with the excited state hyperfine structure of the Cesium D1-line (2019)

Hybrid interfaces between distinct quantum systems play a major role in the implementation of quantum networks. Quantum states have to be stored in memories to synchronize the photon arrival times for entanglement swapping by projective measurements in quantum repeaters or for entanglement purification. Here, we analyze the distortion of a single-photon wave packet propagating through a dispersive and absorptive medium with high spectral resolution. Single photons are generated from a single In(Ga)As quantum dot with its excitonic transition precisely set relative to the Cesium D1 transition. The delay of spectral components of the single-photon wave packet with almost Fourier-limited width is investigated in detail with a 200 MHz narrow-band monolithic Fabry-Pérot resonator. Reflecting the excited state hyperfine structure of Cesium, “slow light” and “fast light” behavior is observed. As a step towards room-temperature alkali vapor memories, quantum dot photons are delayed for 5 ns by strong dispersion between the two 1.17 GHz hyperfine-split excited state transitions. Based on optical pumping on the hyperfine-split ground states, we propose a simple, all-optically controllable delay for synchronization of heralded narrow-band photons in a quantum network.

Behind the fa&#x00E7;ade (2015)

OPC UA (IEC 62541) has proven to be a very rich and versatile technology, not least of which we find with the release of the Field Device Integration standard, FDI, in 2014 [16]. However, when introducing such a standard within products or systems on a broad scale, also economic questions on development effort and footprint must be answered. Ideally, we wish technology to be versatile, time-efficient to implement, and cost-efficient to deploy.
Design and Synthesis of Novel Pegylated 4‐Methylcoumarins (2007)

Coumarins are well known for their antioxidant and anti‐edema activities. Their antioxidant property gets enhanced with a methyl group at the C‐4 position of the pyran ring. To increase the antioxidant potential and their hydrophilicity, a lipase (Novozyme 435) catalyzed copolymerization of 4‐methylcoumarin diesters and polyethylene glycols (PEGs) has been carried out to give novel copolymers.
