Novel aspects of an application of 'zero'-ripple techniques to basic converter topologies (2002)

Based on a short summary of the theoretical basics of the zero-ripple current phenomenon a special zero input current ripple boost converter topology as presented in the literature is investigated. It is shown that the complete suppression of the input current ripple of the system is only given in a theoretical extreme case. For a practical realization only such a ripple reduction of the input current of the basic converter structure is obtained as corresponds to a simple low-pass input filter. This is proven by a detailed analysis also for a zero-ripple Cuk and for a zero-ripple SEPIC converter structure. Furthermore, it is shown that the realization of a zero-ripple Cuk or zero-ripple SEPIC converter is not linked to a magnetic coupling of the input and output inductors, but can also be achieved by a simple rearrangement of the elements of the basic converter structures. There one can see that the operating behavior of a zero input current ripple SEPIC converter is equivalent to the operating behavior of a buck-boost converter stage with LC input filter. Finally, the advantages and disadvantages of the different realization approaches of zero-ripple topologies are compared. Also, an outlook towards the planned further treatment of the topic is given.
Optimizing polyimide cure using infrared spectroscopy and a factorial design (1986)

Abstract The cure of a polyimide derived from pyromellitic dianhydride (PMDA) and oxydianiline (ODA) has been studied using infrared spectroscopy. A factorial experimental design, combined with regression analysis, was used to find the optimum curing conditions. It was shown that five micron films can be cured by heating at 230–250°C for times of five minutes or longer, while samples cured initially at 150°C did not cure completely when heated to higher temperatures.

Assignment of term descriptors to clusters (2002)

An approach to cluster characterization is developed. The clusters are constructed by using one of the user-oriented techniques. If the clusters have been characterized on the basis of user preferences, the representations of documents contained within the clusters need not be scanned to determine the relevance of a cluster of documents to a query. Since the cluster representations are decided by the users, this approach results in a higher precision and recall in document retrieval. A program to interview a user automatically to elicit the constructs and the repertory grid has been implemented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Low Latency End-to-End Streaming Speech Recognition with a Scout Network (2020)

The attention-based Transformer model has achieved promising results for speech recognition (SR) in the offline mode. However, in the streaming mode, the Transformer model usually incurs significant latency to maintain its recognition accuracy when applying a fixed-length look-ahead window in each encoder layer. In this paper, we propose a novel low-latency streaming approach for Transformer models, which consists of a scout network and a recognition network. The scout network detects the whole word boundary without seeing any future frames, while the recognition network predicts the next subword by utilizing the information from all the frames before the predicted boundary. Our model achieves the best performance (2.7/6.4 WER) with only 639 ms latency on the test-clean and test-other data sets of Librispeech.
Two coding strategies for bidirectional associative memory (1990)

Enhancements of the encoding strategy of a discrete bidirectional associative memory (BAM) reported by B. Kosko (1987) are presented. There are two major concepts in this work: multiple training, which can be guaranteed to achieve recall of a single trained pair under suitable initial conditions of data, and dummy augmentation, which can be guaranteed to achieve recall of all trained pairs if attaching dummy data to the training pairs is allowable. In representative computer simulations, multiple training has been shown to lead to an improvement over the original Kosko strategy for recall of multiple pairs as well. A sufficient condition for a correlation matrix to make the energies of the training pairs be local minima is discussed. The use of multiple training and dummy augmentation concepts are illustrated, and theorems underlying the results are presented.
Methodologies for the preparation of soft materials using cryoFIB SEM (2009)

The recent advent of focused ion beam (FIB) technology in combination with the more familiar scanning electron microscope (SEM) is bringing new insights to the characterization of a range of bulk materials. Furthermore, the FIB SEM can be augmented by a cryo-preparation/transfer system, enabling both frozen and frozen-hydrated soft materials to be FIB-milled at low temperature. This provides an opportunity to perform in situ site-specific crosssectioning, and hence study the interior of a bulk material in two and three dimensions, and serves as an alternative to the freeze-fracturing techniques associated with conventional cryo-SEM. For soft materials in particular, the quality of FIB SEM results is dependent on correct preparation of the specimen's top surface, which is rather challenging for specimens at low temperature. We therefore demonstrate methods for 'cold deposition' of a protective, planarising surface layer on a cryo-prepared sample, enabling high-quality cross-sectioning and investigation of structures at the nano-scale.
<scp>d</scp>‐Aspartate stimulation of testosterone synthesis in rat Leydig cells (1999)

D-Aspartate increases human chorionic gonadotropin-induced testosterone production in purified rat Leydig cells. L-Aspartate, D-,L-glutamate or D-,L-asparagine could not substitute for D-aspartate and this effect was independent of glutamate receptor activation. Testosterone production was enhanced only in cells cultured with D-aspartate for more than 3 h. The increased production of testosterone was well correlated with the amounts of D-aspartate incorporated into the Leydig cells, and L-cysteine sulfinic acid, an inhibitor of D-aspartate uptake, suppressed both testosterone production and intracellular D-aspartate levels. D-Aspartate therefore is presumably taken up into cells to increase steroidogenesis. Intracellular D-aspartate probably acts on cholesterol translocation into the inner mitochondrial membrane, the rate-limiting process in steroidogenesis.

Jazzing up JVMs with off-line profile data (2004)

In Java Virtual Machines employing dynamic compilation, there exists a tradeoff between compilation overhead and execution time. The compilation efforts are directed selectively on program hotspots so that gains in performance due to compiled code can overcome compilation cost. Using online profile incurs runtime-profiling overhead. Using only offline profile data might result in selecting cold methods for compilation when offline profile does not mirror current application behavior. Hence we propose a hybrid scheme that incorporates both online and offline profile to identify selective compilation candidates. We also discuss the significance of selective compilation ordering especially in applications which exhibit phase changes with respect to the method invocations it makes. This results in the hotspots of the program also changing as the application executes. Hence it is important for the selective compilation scheme to be highly responsive to phase changes and target the compilation efforts on the new hotspots, as they appear. We propose a temporal event graph for capturing this phase changing behavior of the application (in terms of the method calls it makes) and use this information in making better selective compilation decisions.
Absence of Strong Gate Effects in Electrical Measurements on Phenylene-Based Conjugated Molecules (2003)

The electronic transport characteristics of self-assembled monolayers of phenylene-based π-conjugated molecules were measured in a three-terminal device geometry. The short (∼1 nm) molecules were connected between two gold electrodes with a nearby Al2O3/Al gate electrode. It was possible to fabricate working devices using three of the five molecules investigated. The other two types of molecules led to devices where the Au electrodes were shorted together. Current−voltage characteristics as a function of the gate voltage are presented for the other three molecules. For some devices with 1,3-benzenedithiol, a weak gate effect was observed but no gating effect was observed for devices fabricated with the other molecules. The results are in strong contrast with those reported by Schön et al.

5 Differentiating transient epileptic amnesia from epilepsy in dementia and mild cognitive impairment (2020)

Objectives/Aims Patients with TEA experience epileptic seizures characterised primarily by a transient impairment of memory. These seizures sometimes include brief periods of unresponsiveness and other ictal features, including olfactory hallucinations and motor automatisms. TEA patients also report interictal memory difficulties: autobiographical amnesia, accelerated long-term forgetting, and topographical amnesia. Epileptic seizures in dementia can lead to behavioural arrest and altered responsiveness, as well as periods of increased confusion and amnesia. We aimed to compare and contrast these conditions with the objective of developing a decision aid to distinguish them efficiently in typical clinical settings. Methods This retrospective study examined the case notes of two groups of patients enrolled in two separate studies. The Impairment of Memory in Epilepsy (TIME) study has established a cohort of 115 patients with TEA. The Presentation of Epileptic Seizures in Dementia (PrESIDe) study assessed 144 patients with MCI or dementia and identified a clinical suspicion of epilepsy in 37 (25.7%). The Addenbrooke’s Cognitive Examination - Version III (ACE-III) scores were compared as a measure of cognitive function. The prevalence of several key seizures features in both the TEA and epilepsy in dementia populations were identified. Results The average age of seizure onset in the dementia group was 76.91 years, 15 years older than in the TEA group. A range of seizure features were seen in both groups. PrESIDe patients were more likely to have seizures where loss of awareness was a feature. Automatisms occurred in a similar prevalence across both groups, although olfactory hallucinations were significantly more common in the TEA group, as were seizures where amnesia was the sole manifestation. More than 50% of participants in both groups experienced amnestic episodes on waking. Patients with epilepsy in dementia scored significantly lower than patients with TEA on all domains of the ACE-III. However, despite typically normal results on the ACE-III, patients with TEA demonstrate impairments when recall is tested over longer delays (>24 hrs), or on measures of autobiographical memory. Conclusions In patients with TEA, the onset of seizures occurs at a younger age than in patients who experience seizures as a feature of their dementia, there are also key differences in the types of seizure reported by these two groups of patients. In contrast to patients with dementia, those with TEA commonly perform normally on standard cognitive tests.

A Threshold Determining Method for the Dynamic Filtering in Wireless Sensor Networks Based on Fuzzy Logic (2008)

In sensor networks, nodes can be easily compromised by an adversary because of hostile environments. An adversary may use compromised nodes to inject false reports into the network. The dynamic en-route scheme for filtering false data injection can detect and drop such false reports during the forwarding phase. In this scheme, choosing a threshold value is important, as it trades off between security power and energy consumption. Thus, we should choose the threshold value such that it provides sufficient resilience, yet be small enough to conserve energy. This paper presents a fuzzy-based threshold determining method for the dynamic en-route scheme for filtering false data injection in wireless sensor networks. The base station periodically determines a threshold value with a fuzzy rule-based system. The number of cluster nodes, the value of the key dissemination limit, and the distance from the base station to each cluster are used to determine the threshold value. The resilience and energy efficiency of the proposed method against false data injection attacks are shown by the simulation results. Key words: sensor networks, false reports, en-route filtering, false data injection attack, fuzzy logic, security. 1.
Randomization Designs in Comparative Clinical Trials (1984)

IN a conventionally conducted randomized clinical trial, random assignment to treatment does not lake place until the patient has been demonstrated to be eligible, has had the details of the study explained, including possible risks and benefits of the therapeutic alternatives, and has then agreed to participate. A modification of this randomization procedure, the "randomized-consent design," has recently been introduced into the practice of clinical trials. The intent of this new design, also called prerandomization, is to eliminate what many physicians feel to be a most uncomfortable and difficult aspect of randomized clinical trials: having to obtain the patient's consent . . .
Subset-codebook precoding for 1-bit massive multiuser MIMO (2017)

We consider a massive multiuser MIMO downlink scenario with 1-bit digital-to-analog converters. QPSK information symbols are transmitted to the users by a channel-dependent mapping of the symbols to 1-bit DAC signals that are transmitted from each base station (BS) antenna. The mapping is selected to emulate the desired information bearing QPSK symbols at the users. Non-linear precoding is considered, where the mapping from the information symbols to the transmit antenna signals is selected based on the combination of information symbols. First, a linear quantized precoder is used to create tentative transmit symbols. For each combination of information symbols, a subset of antennas is selected, and an exhaustive search over a limited size codebook of precoding alternatives is performed. The resulting method significantly lowers the error floor caused by quantization, with a complexity that is linear in the number of transmit antennas.
An antidiabetic thiazolidinedione potentiates insulin stimulation of glycogen synthase in rat adipose tissues. (1996)

Thiazolidinedione derivatives are a novel class of insulin-sensitizing agents that have demonstrated effective antidiabetic activity in vivo. Here, the effects of the potent thiazolidinedione derivative, AD-5075, on the rate-limiting enzyme of glycogen synthesis, glycogen synthase, were investigated in cultured rat adipose tissue. Short term preincubation of adipose tissue with AD-5075 potentiated acute insulin stimulation of I-form glycogen synthase activity in a concentration-dependent (EC50 approximately, 61nM) and time-dependent (t1/2 approximately, 2.3 h) manner. The thiazolidinedione derivative increased the responsiveness of I-form glycogen synthase activity to insulin stimulation at both maximal and submaximal insulin concentrations. In contrast, it had no effect on total glycogen synthase activity. Isoproterenol inhibited acute insulin activation of I-form glycogen synthase activity in a dose-dependent manner; maximal inhibition was attained at a concentration of 3 nM. AD-5075 antagonized isoproterenol inhibition of insulin's action. The concentration of glycogenolytic agent required to attain maximal inhibition was increased an order of magnitude in tissue treated with the antidiabetic agent. Short term preincubation of adipose tissue under hyperglycemic conditions (15 or 25 mM glucose) decreased insulin-stimulated I-form glycogen synthase activity. Concurrent treatment of the tissue with AD-5075 abrogated this glucose toxicity-induced inhibition of insulin action. Wortmannin, an inhibitor of phosphatidylinositol 3-kinase, blocked insulin activation of glycogen synthase in a dose-dependent manner. Half-maximal inhibition was observed at approximately 0.3 microM, and maximal inhibition occurred at 1.0 microM. AD-5075 did not antagonize wortmannin's inhibitory action. These results indicate that thiazolidinediones can act directly on adipose tissues to augment an important metabolic effect of insulin and counteract the inhibitory effects of catecholamines or hyperglycemia. As insulin stimulation of glycogen synthase remains wortmannin inhibitable in the presence of AD-5075, the effects of thiazolidinediones on insulin signal transduction may be phosphatidylinositol 3-kinase-dependent.
The effect of air bearing contour design on thermal pole-tip protrusion (2011)

Thermal flying height control has recently been implemented in magnetic recording disk drives to reduce the flying height at the read/write element of magnetic recording sliders. This paper investigates the effect of air bearing contour design on thermal pole-tip protrusion and flying characteristics of magnetic recording sliders. A number of air bearing surface designs are examined to study the relationship between air bearing surface design and efficiency of thermal pole-tip protrusion.
Relation between length, isometric force, and O2 consumption rate in vascular smooth muscle (1975)

The length-tension and length-oxygen consumption rate relationships were studied in bovine mesenteric vein at 37 degrees C. The absence of spontaneous mechanical activity permits straightforward interpretation in terms of active (smooth muscle) and passive components of the vein wall. Longitudinal loops, the predominant smooth muscle component being oriented in the longitudinal (axial) direction, were maximally stimulated using epinephrine (2-5 mug-ml-1). An optimum length for isometric tension development was exhibited at which the passive tension was 25% of the total tension. The population regression indicated that tension was developed at lengths which ranged from 0.33 to 1.41 times the length at which maximum tension was developed. Oxygen consumption was measured using a Clark-type polarographic electrode. Basal oxygen consumption was 0.432 plus or minus 0.014 (n equal to 121) mumol-min-1 (g dry wt)-1. The basal rate was found to be independent of the passive tension. Under conditions of maximal stimulation, the oxygen consumption rate at L-o, the resting length at which the tissue maintained 1 g-wt passive tension, was approximately twice the basal rate. The length dependence of the suprabasal oxygen consumption was parallel to that of the active isometric force. This parallel relation reflected a linear relation between active isometric force (deltaP-o) and suprabasal oxygen consumption rate (deltaJ-o2). The slope of the deltaJ-o2-deltaP-o linear regression was 0.142 plus or minus 0.013 nmol O2-MIN-1 (G-WT-CM)-1. DeltaJ-o2 at the minimum contracted length, at which no active force was developed, was 15-20% of the deltaJ-o2 measured when maximum isometric force was developed. This provides an upper bound to the rate of chemical energy utilization required for activation processes. The length dependence of active isometric force and chemical energy utilization is most simply interpreted in terms of a sliding-filament model.
Insertion of Iodine in a Functionalized Inorganic Layered Solid (2004)

The galleries of a Mg-Al layered double hydroxide have been functionalized by intercalation of (carboxymethyl)-beta-cyclodextrin cavities. The functionalized inorganic solid can adsorb iodine molecules from vapor as well as nonaqueous and aqueous solutions. The adsorbed iodine complexes with the grafted cyclodextrin cavities, disassociating heterolytically to form polyiodide species. Electronic and Raman spectra provide conclusive evidence for the existence of linear symmetric triodide, I(3)(-), and pentaiodide, I(5)(-), species within the cyclodextrin cavities confined in the layered double hydroxide.
Quotient Networks (1982)

A large-network algorithm solves a problem of size N on a network of N processors. We present a method for transforming certain large networks into quotient networks that emulate those large networks with fewer processors. Large-network algorithms are easily modified to execute on the quotient network. The emulations result in no loss in execution efficiency. Quotient networks allow algorithms to be designed assuming any number of processors and executed efficiently at a great savings in hardware cost.
