Robust vehicle lateral stabilization via set-based methods for uncertain piecewise affine systems: Experimental results (2011)

The paper presents the design of a lateral stability controller for ground vehicles based on front steering and four wheels independent braking. The control objective is to track yaw rate and lateral velocity reference signals while avoiding front and rear wheel traction force saturation. Control design is based on an approximate piecewise-affine nonlinear dynamical model of the vehicle. Vehicle longitudinal velocity and driver steering input are modeled as measured disturbances taking values in a compact set. We use a time-optimal control strategy which ensures convergence into a maximal robust control invariant set. This paper presents the controller experimental results on a vehicle equipped with active front steering and differential braking. In particular, tests at high-speed on ice with aggressive driver maneuvers show the effectiveness of the proposed scheme.
Coherent combination method applied to distributed acoustic sensing over deployed multicore fiber (2023)

From Distributed Acoustic Sensing (DAS) measurements over deployed Multi-Core Fiber (MCF), we discuss several signal processing options to enhance the sensing sensitivity, namely core combination and longitudinal averaging.
Path-Based Contextualization of Knowledge Graphs for Textual Entailment (2019)

In this paper, we introduce the problem of knowledge graph contextualization -- that is, given a specific NLP task, the problem of extracting meaningful and relevant sub-graphs from a given knowledge graph. The task in the case of this paper is the textual entailment problem, and the context is a relevant sub-graph for an instance of the textual entailment problem -- where given two sentences p and h, the entailment relationship between them has to be predicted automatically. We base our methodology on finding paths in a cost-customized external knowledge graph, and building the most relevant sub-graph that connects p and h. We show that our path selection mechanism to generate sub-graphs not only reduces noise, but also retrieves meaningful information from large knowledge graphs. Our evaluation shows that using information on entities as well as the relationships between them improves on the performance of purely text-based systems.
Somatic BRCA status in ovarian tumors (2009)

5528 Background: The combined prevalence of BRCA1/2 mutations in germline DNA derived from a population of invasive ovarian cancer patients is up to 15.3%. PARP inhibitor trials are ongoing in patients who carry germline BRCA1/2 mutations. It is important to know whether somatic (non-germline) BRCA changes are present in ovarian tumors, given the predicted sensitivity of BRCA mutation-carrying tumors to PARP inhibitors and other DNA damaging agents. However, a large cohort of ovarian tumor tissues has not been studied to determine the frequency of BRCA deficiency due to additional somatic changes. Methods: BRCA1/2 exons/flanking regions were sequenced in 235 high-grade ovarian cancers and 38 ovarian cancer cell lines. In 112 tumors, we also performed gene expression analysis and copy number arrays with ultradense probe tiling throughout both BRCA genes. Results: For BRCA1, 31 tumors (13.2%) harbored mutations: 23 known deleterious mutations, 1 suspected deleterious mutation, 3 novel indels, 1 novel mis-sense and 3 novel nonsense mutations. For BRCA2, 12/178 sequenced tumors (6.7%) harbored mutations: 8 known deleterious mutations, 1 suspected deleterious mutation and 3 novel indels. Only 3 BRCA1 mutations were detected in 2 cell lines, two known deleterious and 1 a novel 29 base pair deletion. One cell line thus appears to have both a germline and a somatic mutation. BRCA mutation status was associated with a trend to improved progression-free survival (PFS) in univariate analysis (p = 0.17). However, BRCA deficiency (defined by BRCA1/2 gene expression loss (4 tumors) and homozygous deletion (1 tumor) in addition to mutations) was associated with improved PFS in univariate (p = 0.04) and multivariate (p = 0.03) analyses. Conclusions: The frequency of BRCA1/2 mutations in ovarian tumors detected by sequencing regardless of family history is ≈20%, higher than the expected prevalence of germline mutations. In both BRCA1/2 genes, almost 25% of mutations in tumor tissue were novel and not previously seen in germline DNA. We are now sequencing corresponding germline DNA to determine the exact number of these novel mutations that are somatic. Direct analysis of ovarian tumor tissue is likely to expand the number of women with BRCA-deficient tumors beyond that detectable by germline sequencing. [Table: see text]
Bandgap engineering in deep submicron vertical pMOSFETs (2002)

Bandgap engineering in SiGe heterojunction bipolar transistors (HBT) and high-mobility SiGe channel pMOSFETs significantly enhances the device performance. This study, for the first time, further explores the application of Si-SiGe heterostructures in tailoring MOSFET channel potentials for improving the performance of deep submicron pMOSFETs, and provides guidance for experimental work.
The beneficial effect of methylphenidate in ADHD with comorbid separation anxiety (2014)

The objective of this study was to assess the response of subsyndromal separation anxiety (SSSA) symptoms to methylphenidate (MPH) treatment in patients with attention-deficit/hyperactivity disorder (ADHD). A group of patients with ADHD and SSSA (n=42), aged 8-17 years, received 12 weeks of MPH treatment. The severity of SSSA symptoms was assessed using appropriate scales including the Screen for Child Anxiety Related Emotional Disorders and the specially designed Child and Adolescent Separation Anxiety Scale (CASAS). The severity of ADHD symptoms was assessed using the ADHD Rating Scale. The severity of ADHD and separation anxiety reduced significantly and significant positive correlations were found between the changes in ADHD Rating Scale and the total CASAS scores (P=0.012), as well as other relevant subscales of Screen for Child Anxiety Related Emotional Disorders and CASAS. The MPH-related attenuation in the severity of ADHD was associated with a corresponding improvement in separation anxiety related to school. SSSA symptomatology may be secondary to ADHD and thus the alleviation in ADHD symptoms achieved by MPH treatment results in corresponding relief in separation anxiety.
Recovering The Past: A Photographic Documentary Exploring Post-Conflict Reconciliation (2017)

I am a London-based photographer whose great grandfather was shot at the Battle of the Somme in 1916. With this family history and the then fast-approaching centenary commemorations of the First World War in mind, in 2011 I embarked on developing a complex but unique photographic project to be entitled Recovering The Past. Since its completion, Recovering The Past has been exhibited both at the United Nations in Geneva and currently as a component of the centenary commemorations to the Battle of Passchendaele at the In Flanders Fields Museum, in Ypres, Belgium, as part of the Total War display. The project’s 25 images are a montage of my own photographs of the operations of the DOVO-SEDEE bomb disposal team, and archival images of men of the Australian Imperial Force (AIF). The men of the AIF made significant contributions to the fighting in many localized battles that collectively made up the Third Battle of Ypres. Their courageous efforts are acknowledged through the images of this project.
Development of Open-source Software and Gaze Data Repositories for Performance Evaluation of Eye Tracking Systems (2019)

In this paper, a range of open-source tools, datasets, and software that have been developed for quantitative and in-depth evaluation of eye gaze data quality are presented. Eye tracking systems in contemporary vision research and applications face major challenges due to variable operating conditions such as user distance, head pose, and movements of the eye tracker platform. However, there is a lack of open-source tools and datasets that could be used for quantitatively evaluating an eye tracker's data quality, comparing performance of multiple trackers, or studying the impact of various operating conditions on a tracker's accuracy. To address these issues, an open-source code repository named GazeVisual-Lib is developed that contains a number of algorithms, visualizations, and software tools for detailed and quantitative analysis of an eye tracker's performance and data quality. In addition, a new labelled eye gaze dataset that is collected from multiple user platforms and operating conditions is presented in an open data repository for benchmark comparison of gaze data from different eye tracking systems. The paper presents the concept, development, and organization of these two repositories that are envisioned to improve the performance analysis and reliability of eye tracking systems.
Treatment of Trans-Scaphoid Perilunate Injuries of the Wrist using a Nitinol Staple for Fixation (2020)

Treatment of trans-scaphoid perilunate injuries of the wrist presents a clinical challenge for patients and the treating hand surgeon. In the past, traditional treatment consisted of combined volar and dorsal approaches,
MULTI-SUGAR ANALYSIS SYSTEM USING A NOVEL GLUCOSE-3-DEHYDROGENASE ELECTRODE (2002)

A flavoenzyme, glucose-3-dehydrogenase (G3DH) from Halomonas sp. α-15 strain, possessed broad substrate specificity and site-specific reaction against various sugars. We constructed an amperometric enzyme electrode employing G3DH and also developed a multi-sugar analysis system combined with the G3DH sensor and sugar analysis chromatography. This system can discriminate the 4 components of sugar, i.e., glucose, 1,5-anhydro-D-glucitol, trehalose, and N-carbamoyl-β-D-glucopyranosylamine mixture and it can determine each concentration from 2 mM to 10 mM.
Carbapenem-resistant Acinetobacter baumannii and Klebsiella pneumoniae across a hospital system: impact of post-acute care facilities on dissemination (2010)

In this outbreak of carbapenem-resistant A. baumannii and K. pneumoniae across a healthcare system, we illustrate the important role post-acute care facilities play in the dissemination of multidrug-resistant phenotypes.
Measurement of the time-dependent CP asymmetry in B0→J/ψKS0 decays (2013)

in the decay channel B 0 J / K 0 S performed with 1.0 fb -1 of pp collisions at s = 7 TeV collected by the LHCb experiment. The fit to the data yields S J / K 0 S = 0.73 0.07 (stat) 0.04 (syst) and C J / K 0 S = 0.03 0.09 (stat) 0.01 (syst). Both values are consistent with the current world averages and within expectations from the Standard Model.
Set-theoretic DS/CDMA receivers for fading channels by adaptive projected subgradient method (2005)

This paper presents a family of multiple access interference (MAI) suppression receivers based on the adaptive projected subgradient method. The proposed scheme can be applied to many different channel models and modulations in a unified manner. Moreover, it is suitable for both blind and nonblind receivers. The adaptive projected subgradient method realizes excellent convergence to a set including an optimal solution with high probability by asymptotically minimizing a sequence of nonnegative convex functions. Simulation results show much better (variable) tradeoff between speed and performance at steady-state as compared to existing techniques
Charge Transport Orthogonality in All‐Polymer Blend Transistors, Diodes, and Solar Cells (2013)

Polymer aggregation and phase separation of polymer–polymer blends are effectively tuned from self-stratified to laterally phase-separated by adjusting the relative solubility of the two polymers in the mixture. This is found to dramatically alter the charge transport characteristics from a preferential in-plane to an out-of-plane direction, revealing the critical dependence of the resulting device performance on the film morphology and structure of the active layer.

Selective Thallium (I) Ion Sensor Based on Functionalised ZnO Nanorods (2012)

Well controlled in length and highly aligned ZnO nanorods were grown on the gold-coated glass substrate by hydrothermal growth method. ZnO nanorods were functionalised with selective thallium (I) ion ionophore dibenzyldiaza-18-crown-6 (DBzDA18C6). The thallium ion sensor showed wide linear potentiometric response to thallium (I) ion concentrations ( M to M) with high sensitivity of 36.87 ± 1.49 mV/decade. Moreover, thallium (I) ion demonstrated fast response time of less than 5 s, high selectivity, reproducibility, storage stability, and negligible response to common interferents. The proposed thallium (I) ion-sensor electrode was also used as an indicator electrode in the potentiometric titration, and it has shown good stoichiometric response for the determination of thallium (I) ion.
Changes in pH of peritoneal fluid associated with carbon dioxide insufflation during laparoscopic surgery in dogs (2008)

Pneumoperitoneum attributable to CO2 insufflation caused a mild and transient decrease in peritoneal fluid pH in dogs. Changes in peritoneal fluid associated with CO2 insufflation in dogs were similar to those in other animals.
Demonstration of Widely Tunable Single-Chip 10-Gb/s Laser–Modulators Using Multiple-Bandgap InGaAsP Quantum-Well Intermixing (2004)

High-speed wavelength-agile laser-modulators were fabricated for the first time using a quantum-well intermixing processing platform for monolithic integration. Over 19-GHz 3-dB modulator bandwidth was achieved and 10-Gb/s error-free transmission was demonstrated through 75 km of standard fiber.
Whole-body, real-time preclinical imaging of quantum dot fluorescence with time-gated detection (2009)

We describe a wide-field preclinical imaging system optimized for time-gated detection of quantum dot fluorescence emission. As compared to continuous wave measurements, image contrast was substantially improved by suppression of short-lifetime background autofluorescence. Real-time (8 frames/s) biological imaging of subcutaneous quantum dot injections is demonstrated simultaneously in multiple living mice.
PPARγ Agonists Attenuate Palmitate-Induced ER Stress through Up-Regulation of SCD-1 in Macrophages (2015)

Protein expression of ER stress marker was evaluated by Western blot analysis and stearoyl-CoA desaturase1 (SCD-1) mRNA expression was evaluated by qRT-PCR. Macrophage apoptosis was detected by flowcytometry. Pioglitazone and rosiglitazone reduced palmitate-induced phosphorylation of PERK, a marker of ER stress, in RAW264.7, a murine macrophage cell line. Pioglitazone also suppressed palmitate-induced apoptosis in association with inhibition of CHOP expression, JNK phosphorylation and cleavage of caspase-3. These effects of pioglitazone were reversed by GW9662, a PPARγ antagonist, indicating that PPARγ is involved in this process. PPARγ agonists increased expression of SCD-1 that introduces a double bond on the acyl chain of long-chain fatty acid. 4-(2-Chlorophenoxy)-N-(3-(3-methylcarbamoyl)phenyl)piperidine-1-carboxamide, an inhibitor of SCD-1, abolished the anti-ER stress and anti-apoptotic effects of pioglitazone. These results suggest that PPARγ agonists attenuate palmitate-induced ER stress and apoptosis through SCD-1 induction. Up-regulation of SCD-1 may contribute to the reduction of cardiovascular events by treatment with PPARγ agonists.
Carrier Grade Wi-Fi: Air interface requirements and technologies (2014)

The IEEE 802.11 standardization group has recently ratified 802.11ac as the newest major amendment of the 802.11 family of Wi-Fi standards. While 802.11ac has specified a number of improvements over 802.11n such as: (i) 8 spatial streams (ii) mandatory bandwidth of 80 MHz and (iii) multi-user MIMO on the downlink, these improvements mostly target to improve the per-link throughput, and in case of MU-MIMO, traffic performance on the downlink. In order to satisfy the air interface high efficiency requirements and technologies, herein referred to broadly as 5G-Carrier Grade WiFi (5G-CGW), it is important to consider other metrics for system performance, such as area-throughput and Quality of Experience (QoE), which are more relevant in use cases where there can be a dense deployment of access points (APs), and stations (STAs). Recently, 802.11 started a study group called High Efficiency Wi-Fi (HEW) to develop the next generation of Wi-Fi physical (PHY) and medium access control (MAC) protocols that would satisfy these requirements. In this paper we will first provide an overview of the state-of-the-art in 802.11 standards, followed by a discussion on some of the limitations of 802.11ac in use cases of interest such as dense deployments in apartment buildings, stadiums and airports. We will provide an overview and preliminary simulation results of three technologies that have shown promise for meeting the requirements of CGW: (i) Multi-User Parallel Channel Access (MU-PCA) which would allow APs to simultaneously transmit to and to receive from a number of STAs in the frequency domain: enabled through multiplexing. This would alleviate the problem of underutilization of frequency resources caused by the need to support STAs of different bandwidths. (ii) Uplink Multi-User MIMO (UL MU-MIMO): IEEE 802.11ac standardized multi-user simultaneous transmissions in the downlink via downlink MU-MIMO. Uplink MU-MIMO needs to be defined to enable multiple users to share the spatial domain and transmit at the same time in the uplink. (iii) Fractional CSMA and Transmit Power Control (TPC): In a dense deployment of APs, the performance of overlapping basic service sets (BSSs) can be improved by coordinating the transmitted power in the adjacent APs in such a manner that STAs on the edge of coverage face reduced interference.
Iterative identification of fault-prone binaries using in-process metrics (2008)

Code churn, the amount of code change taking place within a software unit over time, has been correlated with fault-proneness in software systems. We investigate the use of code churn and static metrics collected at regular time intervals during the development cycle to predict faults in an iterative, in-process manner. We collected 159 churn and structure metrics from six, four-month snapshots of a 1 million LOC Microsoft product. The number of software faults fixed during each period is recorded per binary module. Using stepwise logistic regression, we create a prediction model to identify fault-prone binaries using three parameters: code churn (the number of new and changed blocks); class Fan In and class Fan Out (normalized by lines of code). The iteratively-built model is 80.0% accurate at predicting fault-prone and non-fault-prone binaries. These fault-prediction models have the advantage of allowing the engineers to observe how their fault-prediction profile evolves over time.

United States isolates of Lawsonia intracellularis from porcine proliferative enteropathy resemble European isolates (1996)

Design and procedure—Three isolates of L. intracellularis were isolated from the intestines of United States pigs with porcine proliferative enteropathy. The organisms were grown and passaged in a rat enterocyte cell line (IEC-18). Growth was not associated with morphological cell change and was monitored by immunostaining of the cells using a monoclonal antibody and by polymerase chain reaction (PCR). The PCR products were evaluated by DNA sequencing and compared to a known sequence from L. intracellularis.
System-level loss minimization of VSI-based induction motor drives (2015)

Applications of motor drives, ranging from automotive traction to more-electric aircraft, have widely varying speed and torque demands. With extensive use of inverter-fed drives, loss minimization techniques for such applications have evolved over the past few decades. Previous work on loss minimization has mainly focused on specific drive components. Component-level loss minimization, however, will not guarantee minimum total loss in the drive system. In this paper, a system-level loss minimization method is developed using a comprehensive loss model, to achieve true minimum total loss in the system. The total loss obtained is lower for the proposed system-based minimization than the component-based methods such as machine loss minimization, torque maximization per stator ampere and dc-link loss minimization. Simulation and experimental results for a sample drive cycle are presented to verify the benefits of the proposed scheme for an induction motor drive. Results suggest system loss reduction of about 7%, when compared to machine-based optimization, in high-variability applications.
Laser Raman and XPS analyses of molybdenum–rare earth oxide catalysts (1991)

Abstract Laser Raman spectroscopy (LRS) and x‐ray photoelectron spectroscopy (XPS), combined with x‐ray diffraction (XRD), have been used to characterize the phases in Mo–RE–O (RE = Sm, Tb, Yb) systems. Two clearly differentiated composition regions were observed, namely the RE‐rich region ( x &lt; 0.5–0.6, where x represents the Mo/(Mo + RE) atomic ratio), in which the RE oxide was always present as a separate phase, and the Mo‐rich region ( x &gt; 0.6) in which MoO 3 appeared as a separate phase. The broadening of the Raman bands in the RE‐rich region is indicative of the presence of ill‐defined structures. However, as the RE oxide content increased, crystalline molybdates with decreasing Mo/RE ratios were found in each system. XPS surface composition was roughly similar to that of the bulk for the Mo–Sm–O and Mo–Yb–O series, while relevance of MoO 3 and molybdate phases in the Mo‐rich composition regions is discussed in the context of allylic oxidation of light olefins.
Numerical investigation of the linearity of graphene-based silicon waveguide modulator (2019)

We investigated the linearity of graphene-based silicon waveguide modulators used in microwave photonics links. A theoretical model was developed to systematically analyze the linearity performance for the second-order harmonic distortions (SHD2) and the third-order intermodulation distortions (IMD3). For the graphene-based silicon waveguide electro-absorption (EA) modulator, the distortions were suppressed through bias optimization. As a result, the maximal spurious free dynamic range (SFDR) obtained for SHD2 and IMD3 were 105.9 dB ·Hz<sup>1/2</sup> and 117.8 dB·Hz<sup>2/3</sup>, respectively. For the graphene-based silicon waveguide electro-refraction (ER) phase modulator, SHD2 was fully eliminated through the push-pull modulation and quadrature biasing, while the remaining IMD3 term was linearized by the proper adjustment of the bias voltage and phase shifter length to obtain an ultrahigh SFDR of 130 dB ·Hz<sup>2/3</sup>. Moreover, the graphene-based silicon waveguide ER modulator is more compact and tolerant to bias errors than a pure silicon modulator. These results reveal that the graphene-based silicon waveguide EA and ER modulators can be potentially utilized in integrated microwave photonics.
SnTe–AgBiTe2 as an efficient thermoelectric material with low thermal conductivity (2014)

SnTe–AgBiTe<sub>2</sub> is not only a solid solution but a nanocomposite. The alloying effect coupled with intense interface scattering leads to considerably decreased lattice thermal conductivity. Bi is much more powerful in neutralizing holes than Sb, giving rise to a much higher Seebeck coefficient. A high <italic>ZT</italic> was then obtained.
