Text-dependent speaker recognition using PLDA with uncertainty propagation (2013)

In this paper, we apply and enhance the i-vector-PLDA paradigm to text-dependent speaker recognition. Due to its origin in text-independent speaker recognition, this paradigm does not make use of the phonetic content of each utterance. Moreover, the uncertainty in the i-vector estimates should be taken into account in the PLDA model, due to the short duration of the utterances. To bridge this gap, a phrase-dependent PLDA model with uncertainty propagation is introduced. We examined it on the RSR-2015 dataset and we show that despite its low channel variability, improved results over the GMM-UBM model are attained.

Dynamic frame-rate selection for live LBR video encoders using trial frames (2008)

Low bit-rate live encoding and streaming of video over wired or wireless channels, as utilized in place-shifting applications, need to adapt the frame rate and bit-rate according to content and channel conditions. Typical rate control schemes work with a given target frame rate and can result in irregular frame skips that are induced by buffer conditions and quantizer saturation. Prior methods proposed to address the dynamic frame-rate selection (DFS) problem work by projecting the impact of a new frame-rate from the operating frame-rate and can have slower convergence to the required frame-rate. In this paper, we propose a scheme that utilizes a given computational capacity (typical in embedded appliances) to actually assess the impact of the new frame-rate by coding at the corresponding new frame-skip (referred to as trial frames) before committing to it. The proposed scheme offers quick content-adaptive convergence to the target frame-rate and maintains a motion-adaptive frame skipping pattern to provide a subjectively pleasing spatio-temporal quality trade-off at the operating bit-rate. In addition, the scheme can work with most existing rate control methods that operate at a supplied frame-rate and is also suitable for hooking to a user controlled quality dial.

Theoretical and experimental study of microstrip-to-slot line uniplanar transition (2002)

Recent advances in MMIC technology makes it possible to construct transitions from CPW-to-microstrip with via hole, microstrip-to-slot line and microshield line-to-CPW all of which have potential applications in the feed network of antennas. In this study we investigated the characteristics of the microstrip-to-slot line uniplanar transition using the finite element method (FEM) and finite difference time domain (FDTD) technique, and compared the theoretical results with the measurements. In both cases, the results agree with the measurements within a few percent.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Quantum‐Dot Solar Cells: Suppressing Interfacial Dipoles to Minimize Open‐Circuit Voltage Loss in Quantum Dot Photovoltaics (Adv. Energy Mater. 48/2019) (2019)

Quantum-dot solar cells have suffered from substantial losses of photovoltage. In article number 1901938, Yeon Sik Jung, Jin Young Kim and co-workers develop and report a bilayer hole-transport layer, which effectively suppresses undesired interfacial dipoles and electron leakage. The new method consequently enables a quantum-dot solar cell with an open-circuit-voltage loss of 450 mV, one of the lowest values reported to date.

This study emphasizes the importance of blood glucose testing, of bolus insulin administration and of an increase in the time of temporary basal rate use in relation to improving glycaemic control.
On RTL scan design (2002)

This paper presents a methodology to insert scan paths in a functional Register Transfer Level (RTL) specification of a design that can exploit existing functional paths between sequential elements in the original circuit for establishing scan chains. The primary objective for RTL scan insertion is to reduce the time taken for DFT, and thus reduce the time to market. Additionally, building scan chains at the functional RT-Level is expected to reduce the total area overhead introduced by full scan without compromising the fault coverage achieved. In addition, it often eliminates the delay associated with the additional multiplexer as a part of a conventional scan-cell in high performance designs. Experimental results presented in this paper demonstrate that the proposed method achieves the above objectives while also achieving higher fault coverages for most of the benchmark circuits considered.

Nonflammable Trimethyl Phosphate Solvent-Containing Electrolytes for Lithium-Ion Batteries: II. The Use of an Amorphous Carbon Anode (2001)

In order to improve the cycling performance of lithium-ion batteries with nonflammable trimethyl phosphate (TMP)-based electrolytes, amorphous carbon (AC) was used as the anode material. It was found that the reduction decomposition of TMP solvent, which occurred without limit on a natural graphite anode and concomitantly generated a large amount of methane and ethylene gases, was considerably suppressed on amorphous carbon anode. This improvement was attributed to the disordered structure of amorphous carbon, which hindered the cointercalation of TMP solvent. The charge/discharge result and cyclic voltammetry further disclosed that a highly stable and passivating surface film, called the solid electrolyte interphase film, was formed on the AC surface at the potential near 1 V. As a result, an ion cell with 1 mol/dm3 (30:30:20:20) nonflammable electrolyte exhibited promising cycling performance. Furthermore, this electrolyte was also found to have good low-temperature performance with the freezing point of <−40°C. Thermal test results disclosed that a lithium-ion cell with 1 mol/dm3 (30:30:20:20) exhibited good thermal stability. © 2001 The Electrochemical Society. All rights reserved.
Cloning and Functional Expression of cDNA Encoding Pheromone Δ9 Acyl‐CoA Desaturase of the Tobacco Cutworm, Spodoptera litura (Lepidoptera: Noctuidae) (2005)

ABSTRACT A cDNA encoding pheromone Δ9 acyl‐CoA desaturase, Slit KPSE was isolated from sex pheromone gland of the tobacco cutworm, Spodoptera litura which uses a diene unsaturated fatty acid (UFA) derivative, Z9E11‐14 : 2 as a major pheromone component. The fulllength open reading frame coding region of Slit KPSE was inserted in a yeast shuttle vector, YEpOLEX, and two kinds of yeast ( Saccharomyces cerevisiae ) mutant strains were transformed with the recombinant vector. In the desaturase‐deficient ole 1 strain, Slit KPSE expressed a complementary enzyme producing two kinds of diene UFAs, more 9–16 : 1 and less 9–18 : 1 at a ratio of 1 : 0.74 exhibiting a typical functional characteristics as one of the pheromone Δ9 acyl‐CoA desaturase lineage group, KPSE, but no Δ9 14C monoene was detectable because of too small amount of 14C saturated fatty acid precursor to be reliably used by Slit KPSE in the transformed cells. However, the another transformed yeast strain elo 1 which is deficient of elongase 1, an enzyme converting 14C to 16C hydrocarbon substrate, was supplemented with some myristic acid (14 : 0) in the medium, and produced a significant amount of 9–14 : 1 in due to a much enhanced level of the 14C substrate suggesting that Slit KPSE may be responsible for making the Δ9 double bond on the diene pheromone component.
MI simulation of an orifice flow in a circular pipe with different beta ratios (2011)

Industrial measurements commonly use orifice flowmeters as a method of flowrate measurement. Aiming for the development of highly functionalized orifice flowmeter in future, the authors have developed the Measurement-integrated (MI) simulation for an orifice flow in a circular pipe. In a present paper, the MI simulation is applied for a flow field including an orifice with a beta ratio of 0.6 or 0.7. Computations of the MI simulation were performed at several constant flow rates. It is found that that the MI simulation can be applied to orifice flows with the beta ratios.

Design and Simulation of UART Serial Communication Module Based on VHDL (2011)

UART (Universal Asynchronous Receiver Transmitter) is a kind of serial communication protocol; mostly used for short-distance, low speed, low-cost data exchange between computer and peripherals. During the actual industrial production, sometimes we do not need the full functionality of UART, but simply integrate its core part. UART includes three kernel modules which are the baud rate generator, receiver and transmitter. The UART implemented with VHDL language can be integrated into the FPGA to achieve compact, stable and reliable data transmission. It's significant for the design of SOC. The simulation results with Quartus II are completely consistent with the UART protocol.
Basis mapping methods for forward and inverse problems (2016)

Summary This paper describes a novel method for mapping between basis representation of a field variable over a domain in the context of numerical modelling and inverse problems. In the numerical solution of inverse problems, a continuous scalar or vector field over a domain may be represented in different finite‐dimensional basis approximations, such as an unstructured mesh basis for the numerical solution of the forward problem, and a regular grid basis for the representation of the solution of the inverse problem. Mapping between the basis representations is generally lossy, and the objective of the mapping procedure is to minimise the errors incurred. We present in this paper a novel mapping mechanism that is based on a minimisation of the L 2 or H 1 norm of the difference between the two basis representations. We provide examples of mapping in 2D and 3D problems, between an unstructured mesh basis representative of an FEM approximation, and different types of structured basis including piecewise constant and linear pixel basis, and blob basis as a representation of the inverse basis. A comparison with results from a simple sampling‐based mapping algorithm shows the superior performance of the method proposed here. © 2016 The Authors.

Communication for Omniscience. (2016)

This paper considers the communication for omniscience (CO) problem: A set of users observe a discrete memoryless multiple source and want to recover the entire multiple source via noise-free broadcast communications. We study the problem of how to attain omniscience with the minimum sum-rate, the total number of communications, and determine a corresponding optimal rate vector. The results cover both asymptotic and non-asymptotic models where the transmission rates are real and integral, respectively. Based on the concepts of submodularity and Dilworth truncation, we formulate a maximization problem. The maximum is the highest Slepian-Wolf constraint over all multi-way cuts of the user set, which determines the minimum sum-rate. For solving this maximization problem and searching for an optimal rate vector, we propose a modified decomposition algorithm (MDA) and a sum-rate increment algorithm (SIA) for asymptotic and non-asymptotic models, respectively, both of which complete in polynomial time. For solving the Dilworth truncation problem as the subroutine in both algorithms, we propose a fusion method to implement the existing coordinate saturation capacity (CoordSatCap) algorithm, where the submodular function minimization (SFM) is done over a merged user set. We show by experimental results that this fusion method contributes to a reduction in computation complexity as compared to the original CoordSatCap algorithm.
Contextual sensing: why we should make sensors "smarter" (Conference Presentation) (2019)

Aside from the daunting physics based challenges needed to maintain Moore's Law, it's becoming increasingly difficult to justify the huge foundry investments required. This probable constraint to future electronics provides sensor developers with a unique opportunity to create more "elegant" sensing design options. Instead of continually increasing the amount of data collected in an open-loop manner, we should consider providing "intelligent" feedback to and within sensors in a more "closed-loop" manner. In other words, allow the sensor to dynamically learn how best to allocate its sampling, processing, and communication resources based on both external objectives and internal conditions. Imbedding deep learning machines into sensors designs could help mitigate Moore's Law's possible demise.
Rolle der zentralen Sensitisierung bei der Wirkung von Triptanen - Schneller, höher, weiter: Ist die moderne Migränetherapie besser?* (2006)

Triptane sind effektive Substanzen zur Behandlung akuter Migräneattacken. Am besten wirksam ist die subkutane Anwendung von Sumatriptan. Selbst bei dieser Anwendungsform beträgt aber die Erfolgsquote nur 50-70 %, d.h. mindestens ein Drittel der Patienten spricht nicht auf diese Behandlung an. Bisher gab es keine gute Möglichkeit, die Wirksamkeit eines Triptans nach klinischen Kriterien vorauszusagen.
Comprehensive Biostatistical Analysis of CpG Island Methylator Phenotype in Colorectal Cancer Using a Large Population-Based Sample (2008)

Our study provides valuable data for standardization of the use of CIMP-high-specific methylation markers. CIMP-high is independently associated with clinical and key molecular features in colorectal cancer. Our data also suggest that KRAS mutation is related with a random CpG island methylation pattern which may lead to CIMP-low tumors.
XPS analysis of the poly(ethylene terephthalate) film grafted with acrylamide (1990)

Abstract Graft polymerization of acrylamide (AAm) was performed onto the surface of a poly(ethylene terephthalate) (PET) film with the simultaneous UV irradiation method but using no photosensitizer and without degassing. To examine whether polyacrylamide (PAAm) was introduced into the bulk place of PET film by the surface graft polymerization, an x‐ray photoelectron spectroscopic (XPS) study was performed on the PAAm‐grafted PET films. The distribution of grafted PAAm chains on and in the PET films was estimated from the PAAm/PET ratio calculated from the XPS spectra of PET films with different amounts of grafted PAAm. The results clearly demonstrate that graft polymerization has actually occurred not merely on the outermost surface but also within the thin surface region of the PET film. In addition, the XPS analysis revealed that the PET component was always present in the grafted surface region by a mole fraction of 0.1 to 0.05 even when the amount of PAAm grafted was larger than 10 μg/cm 2 .
Real-Time TEC Determination for Ionospheric Modeling in WADGPS (1995)

In this paper, an algorithm for the real-time computati-
on of Ionospheric Total Electron Content (TEC) will be
presented. The computation is based on a sequential
least-squares algorithm applied to dual frequency GPS
pseudorange and carrier phase measurements. It will be
shown that this combination enables a strong reduction
of noise on the TEC determination as compared to TEC
values computed from simple frequency differenced
pseudoranges.
Thanks to its real-time processing capability, this al-
gorithm is mainly expected to be implemented in Wide
Area Differential GPS Reference Stations or in Io-
nosphere Monitoring Stations.
Sural Nerve Donor-Site Morbidity (2006)

This study presents a long-term evaluation of sural nerve donor-site morbidity in patients with at least 15 years' follow-up (mean 26 years) after sural nerve harvesting for peripheral nerve repair. Twenty-nine patients (mean age 30 years at time of surgery) participated in a retrospective analysis using a questionnaire. The subjective patient evaluations indicated a significant recovery of the sural nerve donor site with regard to sensory loss, pain, and cold sensitivity over time. Beyond 5 years, no further improvement is to be expected. Our findings provide a guideline for general patient information regarding sural nerve donor-site morbidity. An area of sensory loss of approximately the size of 5 x 6 cm is to be expected, and 20%-30% of the patients experienced minimal levels of pain, cold sensitivity, functional impairment, and scar discomfort. The latter 2 were confined to inconvenience with bumping of the donor site and putting on shoes.

A new model is proposed giving the channel capability of a MB-IR-UWB system versus the number of subband and the duty cycle. The architecture simulated shows data rate ranging from 1.434 Gbits/s to 0.9 Gbits/s for 16 to 10 subbands and duty cycle ranging from 20% to 12%.
Minimally invasive estimation of ventricular dead space volume through use of Frank-Starling curves (2017)

This paper develops a means of more easily and less invasively estimating ventricular dead space volume (Vd), an important, but difficult to measure physiological parameter. Vd represents a subject and condition dependent portion of measured ventricular volume that is not actively participating in ventricular function. It is employed in models based on the time varying elastance concept, which see widespread use in haemodynamic studies, and may have direct diagnostic use. The proposed method involves linear extrapolation of a Frank-Starling curve (stroke volume vs end-diastolic volume) and its end-systolic equivalent (stroke volume vs end-systolic volume), developed across normal clinical procedures such as recruitment manoeuvres, to their point of intersection with the y-axis (where stroke volume is 0) to determine Vd. To demonstrate the broad applicability of the method, it was validated across a cohort of six sedated and anaesthetised male Pietrain pigs, encompassing a variety of cardiac states from healthy baseline behaviour to circulatory failure due to septic shock induced by endotoxin infusion. Linear extrapolation of the curves was supported by strong linear correlation coefficients of R = 0.78 and R = 0.80 average for pre- and post- endotoxin infusion respectively, as well as good agreement between the two linearly extrapolated y-intercepts (Vd) for each subject (no more than 7.8% variation). Method validity was further supported by the physiologically reasonable Vd values produced, equivalent to 44.3-53.1% and 49.3-82.6% of baseline end-systolic volume before and after endotoxin infusion respectively. This method has the potential to allow Vd to be estimated without a particularly demanding, specialised protocol in an experimental environment. Further, due to the common use of both mechanical ventilation and recruitment manoeuvres in intensive care, this method, subject to the availability of multi-beat echocardiography, has the potential to allow for estimation of Vd in a clinical environment.
Naegleria and Acanthamoeba Infections: Review (1990)

Infections caused by small, free-living amebas are still unfamiliar to many clinicians, pathologists, and laboratorians. As of 31 July 1989, more than 140 cases of primary amebic meningoencephalitis caused by Naegleria fowleri and more than 40 cases of granulomatous amebic encephalitis caused by Acanthamoeba species (including two cases in patients with AIDS) and possibly by other free-living amebas had occurred worldwide. The recent increase in acanthamoeba keratitis (more than 200 cases), especially in contact lens wearers, has generated new interest in this group of amebas. Effective treatment is still lacking. Risk factors, clinical manifestations, and laboratory parameters helpful in the recognition of infections of the central nervous system (i.e., granulomatous amebic encephalitis and primary amebic meningoencephalitis) and acanthamoeba keratitis are reviewed.
