Adaptive Data Broadcasting Using Air-Cache (1996)

In the Data AirWaves Project at University of Maryland, we are integrating Direct Broadcast Satellite (DBS) systems with terrestrial networks to provide a hybrid and eective communication substrate lying between data resources and remote/mobile user applications. Smooth integration of these two media balances the need for rapid data dissemination to very large numbers of clients and on{demand interactive data services. This paper describes the air{cache, a method for eective data broadcasting and an algorithm which rapidly adapts the content of the cache based on the \\misses&amp;quot; which result in explicit (on{demand) data requests. Simulation results show that the hypothesis of adapting based only on the misses performs quite reasonably and has very little deviation from a system that has complete information { both hits and misses. This material is based upon work supported by the Center for Satellite and Hybrid Communication Networks under
Dynamic Modeling and Experiment Verification of a Piezoelectric Part Feeder (2005)

The study is aimed to perform dynamic modeling of the part-feeder powered by piezoelectric actuation. This part-feeder consists mainly of a horizontal platform vibrated by a pair of parallel piezoelectric beams. The parts to be transported on the platform march forward owing to their intermittent impacts on the platform. The dynamic modeling technique used herein is essentially the Rayleigh-Ritz method, which first incorporates material properties and constitutive equations of the piezoelectric materials, and then captures the complex dynamics of the parallel-beam piezo-feeder by three lower-order assumed modes in the transverse direction of the vibrating beams. With the three approximated assumed modes in hand, the system dynamics is then represented by three coupled discrete equations of motion. Based on these equations, displacement and velocity of the platform can be approximately obtained. Based on the approximated motions of the platform, the marching speed of the parts with intermittent impacts on the platform can be predicted. Numerical computations are conducted to acquire the estimated marching speed of the parts, along with the experimental study. The comparison between the theoretical predicted transporting speed of the part and the experiment counterparts.
Thermal Stability and Mechanical Properties of Silicone Rubber Composites Filled with Inorganic Fire-proof Fillers and Expandable Materials (2018)

본 연구에는 무기계 내화 필러와 팽창재료를 충전한 실리콘 고무 복합체의 내화 성능과 열적 안정성 및 기계적 강도를 분석하였다. 가스 토치 화염시험과 열 중량분석(TGA)을 통해 미네랄 섬유(mineral fiber)/실리콘 고무 복합체는 규회석(wollastonite)/실리콘 고무 복합체와 운모(mica)/실리콘 고무 복합체보다 내화 성능이 우수하다는 것을 확인하였다. 주사전자현미경(SEM)을 통해 규회석은 실리콘 고무에 분산성이 양호함을 확인하였고, 만능재료분석기(UTM)를 통해 분석한 결과 기계적 강도가 가장 우수했다. 팽창재료(팽창흑연 및 팽창질석) 2종은 가스 토치 화염시험 결과 내화 필러/실리콘 고무 복합체의 내화성능을 보다 향상시킬 수 있다는 것을 확인하였다. 특히, 팽창흑연이 충전된 실리콘 고무 복합체가 팽창질석이 충전된 실리콘 고무 복합체보다 내화성능이 더 우수함을 확인하였다. 하지만, 기계적 특성의 경우, 팽창질석이 충전된 실리콘 고무 복합체가 팽창흑연이 충전된 실리콘 고무 복합체보다 다소 우수하였다.
Fluoropolymers for 157 nm single-layer resists (2003)

Tetrafluoroethylene-based copolymers with functionalized norbornenes were synthesized using a hydrocarbon and hydrofluorocarbon initiators and their fundamental properties, such as transparency at 157 nm and solubility in a standard alkaline developer were characterized. A high transparency, i.e., absorbance of less than 0.5 μm−1, and the increase of the dissolution rate in the standard alkaline developer were achieved. Positive-working resists formulated by the fluororesins were developed and showed fine patterns of 60 nm dense lines and spaces delineated by the exposure at 157 nm wavelength.

Arthrodesis of the First Metatarsophalangeal Joint: A Biomechanical Study Comparing Memory Compression Staples, Cannulated Screws, and a Dorsal Plate (2002)

Arthrodesis of the first metatarsophalangeal joint of 21 matched pairs of cadaver toes was performed in order to compare the strength of three methods of internal fixation: 1. two crossed cannulated screws, 2. a dorsal plate with an oblique 0.062 K-wire, and 3. two compression staples with an oblique 0.062 K-wire. Biomechanical testing with plantar force was carried out, and gapping across the fusion site was measured. Stiffness, load to 1-mm displacement, and force to failure was determined for each specimen. Both the plate and screw constructs were statistically stronger in force to failure and initial stiffness than the compression construct. Compression staples have an advantage in their ease of insertion and theoretical continuous compressive force across an arthrodesis site, but should be supplemented with a cast or other external immobilization until union is achieved.
BI-DIRECTIONAL LATTICE RECURRENT NEURAL NETWORKS FOR CONFIDENCE ESTIMATION (2018)

The standard approach to mitigate errors made by an automatic speech recognition system is to use confidence scores associated with each predicted word. In the simplest case, these scores are word posterior probabilities whilst more complex schemes utilise bi-directional recurrent neural network (BiRNN) models. A number of upstream and downstream applications, however, rely on confidence scores assigned not only to 1-best hypotheses but to all words found in confusion networks or lattices. These include but are not limited to speaker adaptation, semi-supervised training and information retrieval. Although word posteriors could be used in those applications as confidence scores, they are known to have reliability issues. To make improved confidence scores more generally available, this paper shows how BiRNNs can be extended from 1-best sequences to confusion network and lattice structures. Experiments are conducted using one of the Cambridge University submissions to the IARPA OpenKWS 2016 competition. The results show that confusion network and lattice-based BiRNNs can provide a significant improvement in confidence estimation.
Measuring the performance-related effect of supply chain events on manufacturing operations (2012)

Today supply chain event management (SCEM) is an important research area because global and lean supply chains are prone to disturbances (i.e.events).SCEM systems identify these events early and mitigate their effects through counter-measures.The impact of common events like transport delays on scheduled manufacturing operations, however, is difficult to judge before effects have propagated through the production.Thus, to avoid an overly sensitive SCEM system that reacts to every event, an assessment of its probable performance-related effects is required.To this end, the paper proposes and evaluates two aggregated measures that capture the dynamics of system performance as an event's effects unfold over time.The measures support the answering of the question of how and why one supply chain event would be more critical than another.

FFT and filter bank based spectrum sensing for WLAN signals (2011)

As wireless communication devices have increased rapidly, much attention has been paid to the spectrum resources. Cognitive Radio (CR) technology has received increasing attention as a potential approach to utilize more effectively the radio frequency bands. CRs need to dynamically and reliably determine spectral holes which could be used for secondary transmissions. In this study, wideband multichannel spectrum sensing techniques are considered, using either FFT or filter bank based spectrum analysis. We focus on detecting spectral gaps between OFDM-based WLAN signals in the 2.4 GHz ISM band. It is found out that the limited spectral purity of WLAN signals, allowed by the 802.11g specifications, significantly restricts the ability to detect possible weaker signals in the spectral gaps between WLAN channels. Improved spectral purity of the primary signals greatly enhances the sensitivity of spectrum sensing, provided that spectrally well-contained filter bank based spectrum analysis methods are used.
Combining irbesartan and trichlormethiazide enhances blood pressure reduction via inhibition of sympathetic activity without adverse effects on metabolism in hypertensive rats with metabolic syndrome (2014)

Sympathoexcitation and oxidative stress in the brain have pivotal roles in hypertension with metabolic syndrome (MetS). Here, we examined whether oral administration of irbesartan (IRB) and trichlormethiazide (TCM) decreases blood pressure (BP) via inhibiting sympathetic activity through anti-oxidant effects in the brain of spontaneously hypertensive rats (SHR-cp). IRB/TCM treatment decreased BP more profoundly than IRB monotherapy. Urinary norepinephrine excretion and oxidative stress in the brain were decreased in both IRB and IRB/TCM groups without any adverse effect on the metabolic profile. These findings suggest that IRB/TCM profoundly decreases BP in SHR-cp by inhibiting sympathetic activity via anti-oxidant effects in the brain.
Structure and Ligand Binding Properties of Myoglobins Reconstituted with Monodepropionated Heme:  Functional Role of Each Heme Propionate Side Chain, (2007)

Two heme propionate side chains, which are attached at the 6 and 7 positions of the heme framework, are linked with Arg45 and Ser92, respectively, in sperm whale myoglobin. To evaluate the role of each propionate, two kinds of one-legged hemins, 6-depropionated and 7-depropionated protohemins, were prepared and inserted into the apomyoglobin to yield two reconstituted proteins. Structural data of the reconstituted myoglobins were obtained via an X-ray crystallographic analysis at a resolution of 1.1-1.4 A and resonance Raman spectroscopy. It was found that the lack of the 6-propionate reduces the number of hydrogen bonds in the distal site and clearly changes the position of the Arg45 residue with the disrupting Arg45-Asp60 interaction. In contrast, the removal of the 7-propionate does not cause a significant structural change in the residues of the distal and proximal sites. However, the resonance Raman studies suggested that the coordination bond strength of the His93-Fe bond for the protein with the 7-depropionated protoheme slightly increases compared to that for the protein with the native heme. The O2 and CO ligand binding studies for the reconstituted proteins with the one-legged hemes provide an important insight into the functional role of each propionate. The lack of the 6-propionate accelerates the O2 dissociation by ca. 3-fold compared to those of the other reconstituted and native proteins. The lack of the 7-propionate enhances the CO affinity by 2-fold compared to that of the protein with the native heme. These results indicate that the 6-propionate clearly contributes to the stabilization of the bound O2, whereas the 7-propionate plays an important role in the regulation of the Fe-His bond.
Thérapie génique et maladies cardiovasculaires. (1999)

Le systeme cardiovasculaire represente un domaine d'application de la therapie genique a court et a moyen terme, notamment en ce qui concerne le traitement des complications de la maladie atheromateuse. Les progres les plus avances concernent la stimulation de l'angiogenese au cours des maladies ischemiques. L'amelioration fonctionnelle et clinique obtenue recemment apres transfert du gene du VEGF (vascular endothelial growth factor) chez des patients atteints d'arterite ischemique des membres inferieurs offre de nouvelles perspectives therapeutiques. Le transfert de gene utilise dans le traitement de la restenose postangioplastie reste a l'heure actuelle prometteur malgre l'absence d'application clinique. Les mises en pratique de la therapie genique a d'autres problematiques cardiovasculaires apparaissent plus lointaines, conditionnees par une meilleure connaissance des mecanismes physiopathologiques ainsi que par l'amelioration des techniques de transfert de gene.

A Clarification Algorithm for Spoken Dialogue Systems (2006)

The paper presents an algorithm for spoken dialogue systems that uses mixed initiative interactions and identification of multiple call-types to clarify the needs of the user efficiently. The representation of the application domain includes the relationships between key topics in the domain, the prompts used to discern between these topics, and the call-types associated with the topics. This representation is used by the algorithm to maintain the state of the conversation. By maintaining a picture of how all of the information conveyed by the user fits into this domain, regardless of whether it was information specifically requested by the system, the algorithm expedites the clarification process.
Armature Temperature Estimation Insensitive to Rotor Flux Variation for SPMSM (2018)

In order to estimate the armature temperature of a surface permanent magnet synchronous motor (SPMSM), it is important to estimate the armature resistance accurately. In this paper, a novel method is proposed to estimate the armature temperature of the SPMSM. The estimated armature temperature is obtained from the estimated armature resistance, which is estimated independently from the rotor flux in the SPMSM. Finally, the effectiveness of the proposed estimation method was evaluated by the experiment.
Implication of 4E-BP1 protein dephosphorylation and accumulation in pancreatic cancer cell death induced by combined gemcitabine and TRAIL (2017)

Pancreatic cancer cells show varying sensitivity to the anticancer effects of gemcitabine. However, as a chemotherapeutic agent, gemcitabine can cause intolerably high levels of toxicity and patients often develop resistance to the beneficial effects of this drug. Combination studies show that use of gemcitabine with the pro-apoptotic cytokine TRAIL can enhance the inhibition of survival and induction of apoptosis of pancreatic cancer cells. Additionally, following combination treatment there is a dramatic increase in the level of the hypophosphorylated form of the tumour suppressor protein 4E-BP1. This is associated with inhibition of mTOR activity, resulting from caspase-mediated cleavage of the Raptor and Rictor components of mTOR. Use of the pan-caspase inhibitor Z-VAD-FMK indicates that the increase in level of 4E-BP1 is also caspase-mediated. ShRNA-silencing of 4E-BP1 expression renders cells more resistant to cell death induced by the combination treatment. Since the levels of 4E-BP1 are relatively low in untreated pancreatic cancer cells these results suggest that combined therapy with gemcitabine and TRAIL could improve the responsiveness of tumours to treatment by elevating the expression of 4E-BP1.
Selective Evolution of Ligands by Exponential Enrichment to Identify RNA Aptamers against Shiga Toxins (2014)

Infection with Shiga toxin- (Stx-) producing E. coli causes life threatening hemolytic uremic syndrome (HUS), a leading cause of acute renal failure in children. Of the two antigenically distinct toxins, Stx1 and Stx2, Stx2 is more firmly linked with the development of HUS. In the present study, selective evolution of ligands by exponential enrichment (SELEX) was used in an attempt to identify RNA aptamers against Stx1 and Stx2. After 5 rounds of selection, significant enrichment of aptamer pool was obtained against Stx2, but not against Stx1, using a RNA aptamer library containing 56 random nucleotides (N56). Characterization of individual aptamer sequences revealed that six unique RNA aptamers (mA/pC, mB/pA, mC, mD, pB, and pD) recognized Stx2 in a filter binding assay. None of these aptamers bound Stx1. Aptamers mA/pC, mB/pA, mC, and mD, but not pB and pD, partially blocked binding of Alexa 488-labeled Stx2 with HeLa cells in a flow cytometry assay. However, none of the aptamers neutralized Stx2-mediated cytotoxicity and death of HeLa cells.
Adaptive back EMF parameter adjustment of simplified vector control for position sensorless permanent magnet synchronous motors (2008)

A previously reported simplified vector control for position-sensorless permanent magnet synchronous motors can be affected by errors in setting the motor parameters, because no feedback compensator is used. We examine the effects of errors on the steady-state performance of these motors in this paper. It was found that the current amplitude increases when a parameter error is given and the effect of a back EMF parameter error is especially large. We propose a new back EMF parameter adjustment method based on these results. We determined from our simulation and experimental results that the proposed method can compensate for the current increase caused by the parameter error. A theoretical analysis showed that the proposed method is affected by only the daxis inductance parameter Ld. Therefore, even if there are errors in the other motor parameters, the motor current of the constant load condition is minimized by using the proposed method.
Compensation of Dominant Frequency Components of Nonrepeatable Disturbance in Hard Disk Drives (2007)

This paper is concerned with the nonrepeatable runout (NRRO) compensation problem for hard disk drives. After standard servo control, several visible frequency components remain in the spectrum of nonrepeatable position error signal (NRPES). The dominant ones among these frequency components contribute a lot to the track mis-registration (TMR). In this paper, we propose an adaptive compensation scheme for the time-varying dominant frequency component of NRRO. The frequency of the dominant component is estimated online by the least mean squares (LMS) algorithm within a short time window. Based on the frequency estimate, the basis function algorithm is applied to adaptively identify the time-varying magnitude and phase of the dominant component. With the identified frequency, magnitude, and phase, an estimate of the dominant component is constructed and then canceled by the control signal. This scheme is further extended to compensating for multiple frequency components. The performance of this compensation scheme is demonstrated by simulation on a realistic hard disk drive model.
Search for gravitational wave ringdowns from perturbed black holes in LIGO S4 data (2009)

According to general relativity a perturbed black hole will settle to a stationary configuration by the emission of gravitational radiation. Such a perturbation will occur, for example, in the coalescence of a black hole binary, following their inspiral and subsequent merger. At late times the waveform is a superposition of quasinormal modes, which we refer to as the ringdown. The dominant mode is expected to be the fundamental mode, $l=m=2$. Since this is a well-known waveform, matched filtering can be implemented to search for this signal using LIGO data. We present a search for gravitational waves from black hole ringdowns in the fourth LIGO science run S4, during which LIGO was sensitive to the dominant mode of perturbed black holes with masses in the range of $10{M}_{\ensuremath{\bigodot}}$ to $500{M}_{\ensuremath{\bigodot}}$, the regime of intermediate-mass black holes, to distances up to 300 Mpc. We present a search for gravitational waves from black hole ringdowns using data from S4. No gravitational wave candidates were found; we place a 90%-confidence upper limit on the rate of ringdowns from black holes with mass between $85{M}_{\ensuremath{\bigodot}}$ and $390{M}_{\ensuremath{\bigodot}}$ in the local universe, assuming a uniform distribution of sources, of $3.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}\text{ }\text{ }{\mathrm{yr}}^{\ensuremath{-}1}\text{ }{\mathrm{Mpc}}^{\ensuremath{-}3}=1.6\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}3}\text{ }\text{ }{\mathrm{yr}}^{\ensuremath{-}1}{L}_{10}^{\ensuremath{-}1},$where ${L}_{10}$ is ${10}^{10}$ times the solar blue-light luminosity.
Hyperglycemia and Incidence of Frailty and Lower Extremity Mobility Limitations in Older Women (2012)

Hyperglycemia is associated with the development of frailty and lower extremity mobility limitations in older women. Future studies should identify mediators of these relationships.
OSCILLATING RANDOM WALK MODELS FOR GI/G/1 VACATION (1986)

Processors handling multi-class traffic typically alternate between serving a particular class of traffic and performing other tasks, e.g., secondary service tasks or routine maintenance. The stochastic behavior of such systems is modeled by a newly introduced class of Bernoulli GI/G/1 vacation models. For this model, when a vacation is completed and customers are present, a customer is served. When a customer has just been served and other customers are present, the server accepts a customer with fixed probability p or commences a vacation of prespecified random duration with probability 1 - p. Whenever no customers are present, a vacation is taken. When p = 0 or p = 1 this schedule reduces to the previously introduced single service schedule and the exhaustive service schedule, respectively. An analysis of all three schedules on a state space incorporating server vacations is presented using simple methods in the complex plane. It is shown that the recent decomposition results for exhaustive service extend to the more general class of Bernoulli schedules.
