GPS accuracy improvement by satellite selection using omnidirectional infrared camera (2008)

This paper describes a precision positioning technique that can be applied to vehicles in urban areas. The proposed technique mitigates GPS multipath by means of an omnidirectional infrared (IR) camera that can eliminate the need for invisible satellites (a satellite detected by the receiver but without LOS (Line Of Sight)) by using IR images. Some simple GPS multipath mitigation techniques such as installation of antennas away from buildings and using choke ring antennas are well known. Further, various correlator techniques can also be employed. However, when a direct signal cannot be received by the antenna, these techniques do not provide satisfactory results because they presume that the antenna chiefly receives direct signals. On the other hand, the proposed technique can mitigate GPS multipath even if a direct signal cannot be received because it can recognize the surrounding environment by means of an omnidirectional IR camera. With the IR camera, the sky appears distinctively dark; this facilitates the detection of the borderline between the sky and the surrounding buildings, which are captured in white, due to the difference in the atmospheric transmittance rate between visible light and the IR rays. Positioning is performed only with visible satellites having less multipath errors, and without using invisible satellites. With the proposed system, static and kinematic evaluations in which invisible satellites are discriminated through observation using an omnidirectional IR camera are conducted. Hence, signals are received even if satellites are hidden behind buildings; furthermore, exclusion of satellites having large errors from the positioning computation becomes possible. The evaluation results confirm the effectiveness of the proposed technique and the feasibility of highly accurate positioning.
Efforts to secure universal access to HIV/AIDS treatment: a comparison of BRICS countries (2013)

This article illustrates how the BRICS countries have been building their focused leadership, making important high level commitment and national policy changes, and improving their health systems, in addressing the HIV/AIDS epidemics in respective settings. Specific aspects are focused on efforts of creating public provisions to secure universal access to ARVs from the aspects of active responsive system and national program, health system strengthening, fostering local production of ARVs, supply chain management, and information system strengthening. Challenges in each BRICS country are analyzed respectively. The most important contributors to the success of response to HIV/AIDS include: creating legal basis for healthcare as a fundamental human right; political commitment to necessary funding for universal access and concrete actions to secure equal quality care; comprehensive system to secure demands that all people in need are capable of accessing prevention, treatment and care; active community involvement; decentralization of the management system considering the local settings; integration of treatment and prevention; taking horizontal approach to strengthen health systems; fully use of the TRIPS flexibility; and regular monitoring and evaluation to serve evidence based decision making.
Generation and Characterization of a Transgenic Pig Carrying a DsRed-Monomer Reporter Gene (2014)

This red fluorescent pig can serve as a host for other fluorescent-labeled cells in order to study cell-microenvironment interactions, and can provide optimal red-fluorescent-labeled cells and tissues for research in developmental biology, regenerative medicine, and xenotransplantation.
Implementation of a Long-Horizon Model Predictive Control Algorithm on an Embedded System (2021)

This paper deals with the implementation of a long-horizon finite control set model predictive control (FCS-MPC) algorithm on an embedded system. The targeted application is a medium voltage drive system implying a very low switching frequency. The implementation is facilitated by the use of a high level synthesis (HLS) tool, which synthesizes C++ code into VHDL, enabling a higher level of abstraction and faster prototype development. Experimental results based on a small-scale prototype, consisting of a three-level neutral point clamped (NPC) inverter and an induction machine, confirm that the algorithm can be executed in real time within the targeted control period of 25&#x00B5;s. This allows for high switching granularity, and thus favorable steady-state and transient performance.
Nature and origin of asphaltenes in processed coals. Final report. [Especially of initial phases and products] (1979)

The development of improved liquefaction technology requires a thorough understanding of the chemistry and mechanisms involved in converting coals to liquid fuels. The primary objectives of EPRI Project 410-1 were to develop such fundamental understanding of the thermal solvent refining of coal. This report constitutes the final report of a four year study. It consists of three volumes. The first volume contains a critical review of the chemistry and basic limitations of today's developing liquefaction processes; an overall summary of the significance of the results of the four-year project to present-day processes; and a detailed review of the last 1 1/2 years of the project. The second volume contains the bulk of the experimental work in the last 1 1/2 years of the project as well as a literature review of specific topics. Volume III contains the pertinent Appendices. Throughout this report, emphasis is placed on the initial phases of coal liquefaction with special attention to the chemical functionality, structure and properties of the initial products of coal. This chemistry is related to the basic constraints imposed on commercial processes such as achievable reaction times, temperatures, pressures, and production and chemical constitution of recycle solvents which are required for coal conversion. In the critical review of limitations of present-day technology, we attempt to integrate the understanding of the chemistry developed and suggest possible means to improve these processes.
The F-Box Protein Rcy1p Is Involved in Endocytic Membrane Traffic and Recycling Out of an Early Endosome in Saccharomyces cerevisiae (2000)

In Saccharomyces cerevisiae, endocytic material is transported through different membrane-bound compartments before it reaches the vacuole. In a screen for mutants that affect membrane trafficking along the endocytic pathway, we have identified a novel mutant disrupted for the gene YJL204c that we have renamed RCY1 (recycling 1). Deletion of RCY1 leads to an early block in the endocytic pathway before the intersection with the vacuolar protein sorting pathway. Mutation of RCY1 leads to the accumulation of an enlarged compartment that contains the t-SNARE Tlg1p and lies close to areas of cell expansion. In addition, endocytic markers such as Ste2p and the fluorescent dyes, Lucifer yellow and FM4-64, were found in a similar enlarged compartment after their internalization. To determine whether rcy1Delta is defective for recycling, we have developed an assay that measures the recycling of previously internalized FM4-64. This method enables us to follow the recycling pathway in yeast in real time. Using this assay, it could be demonstrated that recycling of membranes is rapid in S. cerevisiae and that a major fraction of internalized FM4-64 is secreted back into the medium within a few minutes. The rcy1Delta mutant is strongly defective in recycling.
Robust quantum data locking from phase modulation (2014)

Quantum data locking is a uniquely quantum phenomenon that allows a relatively short key of constant size to (un)lock an arbitrarily long message encoded in a quantum state, in such a way that an eavesdropper who measures the state but does not know the key has essentially no information about the message. The application of quantum data locking in cryptography would allow one to overcome the limitations of the one-time pad encryption, which requires the key to have the same length as the message. However, it is known that the strength of quantum data locking is also its Achilles heel, as the leakage of a few bits of the key or the message may in principle allow the eavesdropper to unlock a disproportionate amount of information. In this paper we show that there exist quantum data locking schemes that can be made robust against information leakage by increasing the length of the key by a proportionate amount. This implies that a constant size key can still lock an arbitrarily long message as long as a fraction of it remains secret to the eavesdropper. Moreover, we greatly simplify the structure of the protocol by proving that phase modulation suffices to generate strong locking schemes, paving the way to optical experimental realizations. Also, we show that successful data locking protocols can be constructed using random code words, which very well could be helpful in discovering random codes for data locking over noisy quantum channels.
Fully Automatic Segmentation of Head and Neck Organs using Active Appearance Models (2016)

We present a fully automatic model based system for segmenting the mandible, parotid and submandibular glands, brainstem, optic nerves and the optic chiasm in CT images, which won the MICCAI 2015 Head and Neck Auto Segmentation Grand Challenge. The method is based on Active Appearance Models (AAM) built from manually segmented examples via a cancer imaging archive provided by the challenge organisers. High quality anatomical correspondences for the models are generated using a Minimum Description Length (MDL) Groupwise Image Registration method. A multi start optimisation scheme is used to robustly match the model to new images. The model has been cross validated on the training data to a good degree of accuracy, and successfully segmented all the test data.
Stability of Transcendental Fractional Systems i (2018)

We investigate the stability of transcendental fractional systems, in which the transfer function of a system is given by a ratio of transcendental polynomials: polynomial-like functions with transcendental branch points on the real-axis. We derive root locus rules such as asymptote angles, centroid, number of branches, and arrival and departure angles to deduce the overall stability properties of such systems under feedback.

An Experiments on 40Gbit/s*8 WDM Transmission through an OPGW (2004)

A field experiment on transmission of eight 40-Gbit/s WDM channels is successfully carried out, where a 240-km optical transmission line is composed of four 60-km SMFs in an OPGW and three optical amplifiers. A few experimental studies on effective optical pulse waveforms for the transmission are made prior to the experiment. A carrier-suppressed RZ format is certified useful for increasing the dispersion compensation tolerance and the allowable optical input power to optical fibers. It is also found to be favorable against the polarization dispersion that pulse-width shortening by an EA modulator in front of the O/E converter. Applicability of the OPGW to 40-Gbit/s optical systems is clarified through error free transmission in all wavelengths.
Bootstrap and aggregating VQ classifier for speakerrecognition (1999)

A bootstrap and aggregating (bagging) vector quantisation (VQ) classifier is proposed for speaker recognition. This method obtains multiple training data sets by resampling the original training data set, and then integrates the corresponding multiple classifiers into a single classifier. Experiments involving a closed set, text-independent and speaker identification system are carried out using the TIMIT database. The proposed bagging VQ classifier shows considerably improved performance over the conventional VQ classifier.
Enzymes in Organic Synthesis: Application to the Problems of Carbohydrate Recognition (Part 2) (1995)

Abstract Recognition of carbohydrates by proteins and nucleic acids is highly specific, but the dissociation constants are relatively high (generally in the m M to high μ M range) because of the lack of hydrophobic groups in the carbohydrates. The high specificity of this weak binding often comes from many hydrogen bonds and the coordination of metal ions as bridge between sugars and receptors. Though weak hydrophobic interactions between sugars and proteins have also been identified, the unique shape of a complex carbohydrate under the influence of anomeric and exo anomeric effects (the glycosidic torsion angles are therefore often not flexible but are typically somewhat restricted) and the topographic orientation of the hydroxyl and charged groups contribute most significantly to the recognition process. Studies on the structure–function relationship of a complex carbohydrate therefore require deliberate manipulation of its shape and functional groups, and synthesis of oligosaccharide analogs from modified monosaccharides is often useful to address the problem. The availability of various monosaccharides and their analogs for the synthesis of complex carbohydrates together with the information resulting from structural studies (such a NMR or X‐ray studies on sugar–protein complexes) will certainly provide a basic understanding of complex carbohydrate recognition. An ultimate goal is to develop simple and easy‐to‐make non‐carbohydrate molecules that resemble the active structure involved in carbohydrate–receptor interaction or the transition‐state of an enzyme‐catalyzed transformation (for example, glycosidase or glycosyltransferase reactions) and have the approprite bioavailability to be used to control the carbohydrate function in a specific manner. In part one of this review we described various enzymatic approaches to the synthesis of monosaccharides, analogs, and related structures. We describe in this part enzymatic and chemoenzymatic approaches to the synthesis of oligosaccarides and analogs, including those involved in E‐selectin recognition, and strategies to inhibit glycosidases and glycosyltransferases.

New insights into micro/nanoscale combined probes (nanoAuger, μXPS) to characterize Ag/Au@SiO2core–shell assemblies (2014)

This work has examined the elemental distribution and local morphology at the nanoscale of core@shell Ag/Au@SiO2 particles. The characterization of such complex metal/insulator materials becomes more efficient when using an initial cross-section method of preparation of the core@shell nanoparticles (ion milling cross polisher). The originality of this route of preparation allows one to obtain undamaged, well-defined and planar layers of cross-cut nano-objects. Once combined with high-resolution techniques of characterization (XPS, Auger and SEM), the process appears as a powerful way to minimize charging effects and enhance the outcoming electron signal (potentially affected by the topography of the material) during analysis. SEM experiments have unambiguously revealed the hollow-morphology of the metal core, while Auger spectroscopy observations showed chemical heterogeneity within the particles (as silver and gold are randomly found in the core ring). To our knowledge, this is the first time that Auger nano probe spectroscopy has been used and successfully optimized for the study of some complex metal/inorganic interfaces at such a high degree of resolution (≈12 nm). Complementarily, XPS Au 4f and Ag 3d peaks were finally detected attesting the possibility of access to the whole chemistry of such nanostructured assemblies.
Drugs affecting lactation. (1979)

The effects of a variety of drugs on lactation are described. Drugs affect lactation either by modifying breast tissue or by influencing prolactin secretion. Androgens and progesterones stimulate the growth of breast tissue, and estrogens, which are frequently used to suppress lactation, stimulate breast duct growth. Many psychotropic drugs increase prolactin levels and cause galactorrhea while other centrally acting drugs inhibit lactation. The names and the mechanism of action of all centrally acting drugs which cause galactorrhea and of all those known to inhibit lactation are provided in tabular form. Suggestions related to the clinical use of the sex steroids and the centrally acting drugs are 1) the use of estrogens to suppress lactation should be limited to the shortest possible time; 2) if galactorrhea occurs in a menopausal patient who is taking oral contraceptives or estrogens, she should be examined for pituitary tumor; 3) if galactorrhea occurs in a patient who is taking a centrally acting drug known to cause galactorrhea, the patient need not be examined for pituitary tumor unless other symptoms are present; 4) the use of centrally acting drugs by women predisposed to breast cancer should be avoided; 5) nursing mothers should avoid taking large doses of barbiturates and pyridoxine as these drugs may reduce lactation; and 6) the use of bromocryptine to suppress postpartum lactation may stimulate early ovulation, and patients should be warned about the need to use contraceptives.
Design, modeling and controllability of a spherical mobile robot (2007)

A spherical mobile robot, rolling on a plane with the help of two internal rotors and working on the principle of conservation of angular momentum has recently been fabricated in our group. The robot is a classic example of a nonholonomic system for which many existing algorithms do not easily apply. The objective is to study feasible path planning algorithms on this system. In this paper, we present the design details of the spherical robot fabricated along with the hardware used. We use Euler parameters which describe a unit quaternion for orientation of the robot and develop mathematical model to avoid singularity problem. We also prove controllability of the system in the quaternion space.
Metabolic signature in nucleus accumbens for anti-depressant-like effects of acetyl-L-carnitine (2020)

Emerging evidence suggests that hierarchical status provides vulnerability to develop stress-induced depression. Energy metabolic changes in the nucleus accumbens (NAc) were recently related to hierarchical status and vulnerability to develop depression-like behavior. Acetyl-L-carnitine (LAC), a mitochondria-boosting supplement, has shown promising antidepressant-like effects opening therapeutic opportunities for restoring energy balance in depressed patients. We investigated the metabolic impact in the NAc of antidepressant LAC treatment in chronically-stressed mice using <sup>1</sup>H-magnetic resonance spectroscopy (<sup>1</sup>H-MRS). High rank, but not low rank, mice, as assessed with the tube test, showed behavioral vulnerability to stress, supporting a higher susceptibility of high social rank mice to develop depressive-like behaviors. High rank mice also showed reduced levels of several energy-related metabolites in the NAc that were counteracted by LAC treatment. Therefore, we reveal a metabolic signature in the NAc for antidepressant-like effects of LAC in vulnerable mice characterized by restoration of stress-induced neuroenergetics alterations and lipid function.
RFID Data-Driven Vehicle Speed Prediction via Adaptive Extended Kalman Filter (2018)

The traditional speed prediction generally utilizes the Global Position System (GPS) and video images, and thus, the prediction precision mainly depends on environmental factors (i.e., weather, ionosphere, troposphere, air, and electromagnetic waves). We study the Radio Frequency Identification (RFID) data-driven vehicle speed prediction and proposed an improved extended kalman filter (i.e., the adaptive extended kalman filter, AEKF) algorithm. Firstly, the on-board RFID reader equipped in the vehicle reads the information (i.e., current speed and time) from the tag deployed on the road. Secondly, the received information is transmitted to the on-board information processing unit, and it is demodulated and decoded into available information. Finally, based on the vehicle state space model, the AEKF algorithm is proposed to predict vehicle speed and improve the prediction results, so that the vehicle speed gradually approaches the actual vehicle speed. The simulation results show that compared with the conventional extended kalman filter (EKF) algorithm, our proposed AEKF algorithm improves the dynamic performance of the filtering and better suppresses the filtering divergence process. Moreover, the AEKF algorithm also improves the precision of the Mean Square Error (MSE) and Mean Absolute Error (MAE) by 57.4% and 32.4%, respectively.
Magnetic Gel Composites for Hyperthermia Cancer Therapy (2015)

Hyperthermia therapy is a medical treatment based on the exposition of body tissue to slightly higher temperatures than physiological (<i>i.e.</i>, between 41 and 46 °C) to damage and kill cancer cells or to make them more susceptible to the effects of radiation and anti-cancer drugs. Among several methods suitable for heating tumor areas, magnetic hyperthermia involves the introduction of magnetic micro/nanoparticles into the tumor tissue, followed by the application of an external magnetic field at fixed frequency and amplitude. A very interesting approach for magnetic hyperthermia is the use of biocompatible thermo-responsive magnetic gels made by the incorporation of the magnetic particles into cross-linked polymer gels. Mainly because of the hysteresis loss from the magnetic particles subjected to a magnetic field, the temperature of the system goes up and, once the temperature crosses the lower critical solution temperature, thermo-responsive gels undergo large volume changes and may deliver anti-cancer drug molecules that have been previously entrapped in their networks. This tutorial review describes the main properties and formulations of magnetic gel composites conceived for magnetic hyperthermia therapy.
Motion Information and Coding Mode Reuse for MPEG-2 to H.264 Transcoding (2005)

MPEG-2 to H.264/AVC transcoding is an interesting research topic and has wide applications. This paper proposes a motion vector and coding mode re-use process for MPEG-2 to H.264 main profile transcoding. Experimental results show that the proposed approach can significantly reduce the computational complexity of the transcoder without sacrificing the rate-distortion performance.
