Collaborative and Adversarial Network for Unsupervised Domain Adaptation (2018)

In this paper, we propose a new unsupervised domain adaptation approach called Collaborative and Adversarial Network (CAN) through domain-collaborative and domain-adversarial training of neural networks. We add several domain classifiers on multiple CNN feature extraction blocks <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> , in which each domain classifier is connected to the hidden representations from one block and one loss function is defined based on the hidden presentation and the domain labels (e.g., source and target). We design a new loss function by integrating the losses from all blocks in order to learn domain informative representations from lower blocks through collaborative learning and learn domain uninformative representations from higher blocks through adversarial learning. We further extend our CAN method as Incremental CAN (iCAN), in which we iteratively select a set of pseudo-labelled target samples based on the image classifier and the last domain classifier from the previous training epoch and re-train our CAN model by using the enlarged training set. Comprehensive experiments on two benchmark datasets Office and ImageCLEF-DA clearly demonstrate the effectiveness of our newly proposed approaches CAN and iCAN for unsupervised domain adaptation.
Synthesis, Structural and Dielectric Studies of Nickel Substituted Cobalt-Zinc Ferrite (2010)

Nano particles of Co(0.5-x)NixZn0.5Fe2O4 (x = 0 to 0.3) is prepared by co-precipitation method. The X-ray diffraction analysis indicates the formation of single phase ferrite particle in nano size. The lattice constant for Co0.5Zn0.5Fe2O4 is found to be 8.38 Å, but the lattice constant decreases when cobalt is replaced by nickel up to x = 0.2 content. The formation of Fe2+ in octahedral site increases the lattice constant for the concentration x = 0.3. The dielectric constant of Co0.5Zn0.5Fe2O4 is found to be less than the bulk sample. The migration of Fe3+ ion from octahedral site to tetrahedral site decreases the dielectric constant with increase in nickel concentration. The charge libration and electron hoping together form the basis for the conduction mechanism in this present compound.
Acoustoelectric interaction of plate modes with solutions (1988)

Acoustic plate mode (APM) devices operating in liquids have an associated electric field which extends several micrometers into the liquid and is capable of interacting with ions and dipoles in solution. Experiments have been performed using quartz APM devices which demonstrate these acoustoelectric interactions. Changes in the dielectric constant or conductivity of solutions in contact with the device were found to perturb the propagation velocity of the plate mode. An equivalent circuit is proposed to describe the interaction of the electric field with ions and dipoles. From this simple model we obtain the velocity shift and attenuation which should occur as a result of this interaction and compare the model predictions to the experimentally observed trends.
The GABA<sub>A</sub>Receptor α+β− Interface: A Novel Target for Subtype Selective Drugs (2011)

GABA(A) receptors mediate the action of many clinically important drugs interacting with different binding sites. For some potential binding sites, no interacting drugs have yet been identified. Here, we established a steric hindrance procedure for the identification of drugs acting at the extracellular α1+β3- interface, which is homologous to the benzodiazepine binding site at the α1+γ2- interface. On screening of >100 benzodiazepine site ligands, the anxiolytic pyrazoloquinoline 2-p-methoxyphenylpyrazolo[4,3-c]quinolin-3(5H)-one (CGS 9895) was able to enhance GABA-induced currents at α1β3 receptors from rat. CGS 9895 acts as an antagonist at the benzodiazepine binding site at nanomolar concentrations, but enhances GABA-induced currents via a different site present at α1β3γ2 and α1β3 receptors. By mutating pocket-forming amino acid residues at the α1+ and the β3- side to cysteines, we demonstrated that covalent labeling of these cysteines by the methanethiosulfonate ethylamine reagent MTSEA-biotin was able to inhibit the effect of CGS 9895. The inhibition was not caused by a general inactivation of GABA(A) receptors, because the GABA-enhancing effect of ROD 188 or the steroid α-tetrahydrodeoxycorticosterone was not influenced by MTSEA-biotin. Other experiments indicated that the CGS 9895 effect was dependent on the α and β subunit types forming the interface. CGS 9895 thus represents the first prototype of drugs mediating benzodiazepine-like modulatory effects via the α+β- interface of GABA(A) receptors. Since such binding sites are present at αβ, αβγ, and αβδ receptors, such drugs will have a much broader action than benzodiazepines and might become clinical important for the treatment of epilepsy.
Rapid Ultraperformance Liquid Chromatography–Tandem Mass Spectrometry Assay for a Characteristic Glycogen-Derived Tetrasaccharide in Pompe Disease and Other Glycogen Storage Diseases (2012)

The UPLC-MS/MS assay of Glc₄ in urine was discriminative between Glc₄ and M₄ and confirmed the diagnosis in >98% of GSD-II cases.
Reduced Graphene Oxide Supported Palladium Nanoparticles via Photoassisted Citrate Reduction for Enhanced Electrocatalytic Activities (2014)

Reduced graphene oxide (rGO) supported palladium nanoparticles (Pd NPs) with a size of ∼3 nm were synthesized using one-pot photoassisted citrate reduction. This synthetic approach allows for the formation and assembly of Pd NPs onto the rGO surface with a desired size and can be readily used for other metal NP preparation. The prepared rGO-Pd exhibited 5.2 times higher mass activity for ethanol oxidation reaction than the commercial platinum/carbon (Pt/C). In the oxygen reduction reaction tests, rGO-Pd exhibited comparable activity compared with Pt/C and maintained its high performance after 4000 cycles of potential sweep. These results demonstrate that our synthetic approach is effective for preparing graphene-supported metal NPs with excellent activity and stability in ethanol oxidation and oxygen reduction reactions.
Online ARIMA Algorithms for Time Series Prediction (2016)

Autoregressive integrated moving average (ARIMA) is one of the most popular linear models for time series forecasting due to its nice statistical properties and great flexibility. However, its parameters are estimated in a batch manner and its noise terms are often assumed to be strictly bounded, which restricts its applications and makes it inefficient for handling large-scale real data. In this paper, we propose online learning algorithms for estimating ARIMA models under relaxed assumptions on the noise terms, which is suitable to a wider range of applications and enjoys high computational efficiency. The idea of our ARIMA method is to reformulate the ARIMA model into a task of full information online optimization (without random noise terms). As a consequence, we can online estimation of the parameters in an efficient and scalable way. Furthermore, we analyze regret bounds of the proposed algorithms, which guarantee that our online ARIMA model is provably as good as the best ARIMA model in hindsight. Finally, our encouraging experimental results further validate the effectiveness and robustness of our method.
Improved Optical Quality for Ti:Sapphire using MRF (2008)

Magneto-rheological finishing (MRF) imprinting techniques have been applied to Ti:sapphire crystals to compensate for submillimeter distortions, thereby, improving the transmitted wavefront and increasing the availability of large aperture parts.
Carotid bifurcation: MR imaging. Work in progress. (1988)

To devise and implement an in-plane magnetic resonance angiography examination of the carotid bifurcation capable of producing high-resolution images, the authors examined 19 normal carotid arteries and 14 patients with angiographically documented disease with two flow-correction techniques: a three-gradient, velocity-refocused technique with spin-echo (SE) and gradient-echo sequences, and a four-gradient velocity- and acceleration-corrected SE technique. With use of three equal gradients in the read direction, velocity-related phase changes were minimized by placing the dephasing gradient after the 180 degree pulse and near the read gradient. Acceleration effects were minimized through the use of short echo times and cardiac gating. Both velocity- and acceleration-produced phase changes were corrected with the four-gradient scheme but at the expense of some limitations in spatial resolution. Both techniques consistently produced satisfactory images of the carotid bifurcation in healthy individuals. However, the results indicate that the present gradient-phase modulation techniques have several drawbacks, including susceptibility to patient motion, overlapping with the jugular vein, and inability to image carotid stenosis accurately due to turbulence.
Multi-stage axial-flux PM machine for wheel direct drive (2002)

The design of direct-drive wheel motors must comply with a diameter restriction due to housing the motor in a wheel rim, and must allow the achievement of very high torque density and overload capability. Slotless axial-flux permanent magnet machines (AFPMs) prove to be one of the best candidates for application in electric vehicles as direct-drive wheel motors, as in comparison with conventional machines they allow designs with higher compactness, lightness and efficiency. The paper presents a newly-conceived AFPM which has multi-stage structure and water-cooled ironless stator. In the proposed new machine topology, the space formerly occupied by the toroidal core becomes a water duct, which removes heat directly from the interior surface of the stator winding. The high efficiency of the machine cooling arrangement allows long-term 100% overload operation and great reduction of the machine weight. The multistage structure of the machine is suited to overcome the restriction on the machine diameter and meet the torque required at the wheel shaft. The paper gives guidelines for the design of a multi-stage AFPM with water-cooled ironless stator, and describes characteristics of a two-stage prototype machine rated 220 Nm, 1100 RPM.
Small forwarding tables for fast routing lookups (1997)

For some time, the networking community has assumed that it is impossible to do IP routing lookups in software fast enough to support gigabit speeds. IP routing lookups must find the routing entry with the longest matching prefix , a task that has been thought to require hardware support at lookup frequencies of millions per second.We present a forwarding table data structure designed for quick routing lookups. Forwarding tables are small enough to fit in the cache of a conventional general purpose processor. With the table in cache, a 200 MHz Pentium Pro or a 333 MHz Alpha 21164 can perform a few million lookups per second. This means that it is feasible to do a full routing lookup for each IP packet at gigabit speeds without special hardware.The forwarding tables are very small, a large routing table with 40,000 routing entries can be compacted to a forwarding table of 150-160 Kbytes. A lookup typically requires less than 100 instructions on an Alpha, using eight memory references accessing a total of 14 bytes.
A Methodology for Introducing Competitive Anxiety and Pressure in VR Sports Training (2015)

Athletes' performances are influenced by internal and external factors, including their psychological state and environmental factors, especially during competition. As a consequence, current training programs include stress management. In this paper, we explore whether highly immersive systems can be used for such training programs. First, we propose methodological guidelines to design sport training scenarios both on considering the elements that a training routine must have, and how external factors might influence the participant. The proposed guidelines are based on Flow and social-evaluative threat theories. Second, to illustrate and validate our methodology, we designed an experimental setup reproducing a ten meter Olympic pistol shooting. We analyzed whether changes in the environment are able to induce changes in user performance, physiological responses and the subjective perception of the task. The simulation included stressors in order to raise a social-evaluative threat, such as aggressive public behavior or unforced errors, increasing the pressure while performing the task. The results showed significant differences in their subjective impressions, trends in the behavioral and physiological data were also observed. Taken together, our results suggest that highly immersive systems could be further used for training in sports.
Synthesis of Au(I) Trifluoromethyl Complexes. Oxidation to Au(III) and Reductive Elimination of Halotrifluoromethanes (2014)

Au(I) trifluoromethyl complexes [Au(CF3)L] (L = N-heterocyclic carbene (NHC), isonitrile, phosphine, P(OMe)3) and [Au2(CF3)2(μ-dppe)] are prepared by reaction of [Au(X)L] (X = Cl, I) or [Au2Cl2(μ-dppe)], respectively, with AgF and Me3SiCF3. The analogous reaction of PPN[Au(C6F5)Cl] (PPN+ = [Ph3PNPPh3]+) gives a mixture of complexes of the type PPN[Au(CF3)x(C6F5)2–x] (x = 0, 1, 2). Single crystals of the new complex PPN[Au(CF3)(C6F5)] are obtained by liquid diffusion from this mixture, and its crystal structure was determined by X-ray diffraction. Acyclic diaminocarbene complexes [Au(CF3){C(NEt2)(NHR)}] (R = tBu, 2,6-dimethylphenyl) are obtained by reaction of [Au(CF3)(CNR)] with NHEt2. Oxidation of the NHC complex [Au(CF3)(IPr)] (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) with PhICl2, Br2, I2 or ICl affords [Au(CF3)(X)(Y)(IPr)] (X = Y = Cl, Br I; X = Cl, Y = I). The dicloro, dibromo, and chloro(iodo) complexes are stable in solution in the dark. In contrast, the diiodo complex is unstable and decomposes to [AuI(IPr)] and ICF3. Under photoirradiation, complexes [Au(CF3)(X)(Y)(IPr)] undergo reductive elimination to give YCF3 and [AuX(IPr)] (X = Y = Cl, Br; X = Cl, Y = I).

The preparation and anthelmintic activities of a series of 2-pyridinyl-5-isothiocyanatobenzimidazoles are described. In the primary oral mouse screen, six derivatives showed 100% taeniacidal activity at 0.2% in diet. The most active member in this series, 1c, is potentially an effective gastrointestinal nematocide in sheep at 50 mg/kg po.
Alternatives to methyl bromide for control of quarantine pests: can composting of bark provide consistent lethal heat accumulation? (2003)

Fuel cells for vehicle propulsion applications: a thermodynamic systems analysis (2003)

The liquid- and air-cooled phosphoric acid, the proton exchange membrane, and the monolithic solid oxide fuel cell systems are analyzed for use in vehicle propulsion applications. System efficiency and input energy distribution are examined as a function of electrochemical fuel utilization and other operating parameters. The liquid-cooled phosphoric acid and the monolithic solid oxide fuel cell systems have efficiencies approaching 40%; the air-cooled phosphoric acid and the proton exchange membrane fuel cells offer efficiencies near 30%. Thus the efficiencies of all of these fuel cell systems are much greater than the efficiencies of internal combustion engines. The analyses indicate further that these fuel cells should be operated at the highest practical electrochemical fuel utilization rates for best efficiency and dynamic response, as well as minimum component volume and cost.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Blinded Comparison of Repetitive-Sequence PCR and Multilocus Sequence Typing for Genotyping Methicillin-Resistant <i>Staphylococcus aureus</i> Isolates from a Children's Hospital in St. Louis, Missouri (2006)

We performed a blinded study to compare repetitive-sequence PCR and multilocus sequence typing for genotyping hospital- and community-acquired methicillin-resistant Staphylococcus aureus (MRSA). The MRSA strains that were sequence type 8 (ST8), staphylococcal cassette chromosome mec (SCCmec) type IV, and Panton-Valentine leukocidin-positive clustered separately from those that were ST5 and SCCmec type II.
On bad habits that occur among those who play instruments (2011)

Since I am an instrument maker, I am obliged to receive all sorts of persons in my shop. Some come to see and hear my products, others come to buy, and thus I have the pleasure of seeing all sorts of people play, and of witnessing all the grimaces and postures that are affected. Many people are not careful about these things, and the masters who instruct cannot be observing very well, as their students must be doing as they are taught. I, however, note everything but tell them nothing. I used to speak freely to them, but I realized that some of them took it ill, so I have restrained myself from taking this great liberty, and I have decided to do my speaking on paper. Perhaps people will not be so readily offended by this as by the spoken word.
Neural correlates of the motivational and somatic components of naloxone‐precipitated morphine withdrawal (2002)

In morphine-dependent rats, low naloxone doses have been shown to induce conditioned place aversion, which reflects the negative motivational component of opiate withdrawal. In contrast, higher naloxone doses are able to induce a 'full' withdrawal syndrome, including overt somatic signs. The c-fos gene is commonly used as a marker of neuronal reactivity to map the neural substrates that are recruited by various stimuli. Using in situ hybridization, we have analysed in the brain of morphine-dependent rats the effects of acute withdrawal syndrome precipitated by increasing naloxone doses on c-fos mRNA expression. Morphine dependence was induced by subcutaneous implantation of slow-release morphine pellets for 6 days and withdrawal was precipitated by increasing naloxone doses inducing the motivational (7.5 and 15 micro g/kg) and somatic (30 and 120 micro g/kg) components of withdrawal. Our mapping study revealed a dissociation between a set of brain structures (extended amygdala, lateral septal nucleus, basolateral amygdala and field CA1 of the hippocampus) which exhibited c-fos mRNA dose-dependent variations from the lowest naloxone doses, and many other structures (dopaminergic and noradrenergic nuclei, motor striatal areas, hypothalamic nuclei and periaqueductal grey) which were less sensitive and recruited only by the higher doses. In addition, we found opposite dose-dependent variations of c-fos gene expression within the central (increase) and the basolateral (decrease) amygdala after acute morphine withdrawal. Altogether, these results emphasize that limbic structures of the extended amygdala along with the lateral septal nucleus, the basolateral amygdala and CA1 could specifically mediate the negative motivational component of opiate withdrawal.

Laser Therapy of Breast Cancer with 3-Year Follow-up (2004)

Breast cancer is the commonest female malignancy in the United States and is increasingly being detected at a non-palpable stage by annual mammography. Minimally invasive methods of its local treatment have been recently introduced as alternative to its surgical removal. The case reported in this article illustrates the advantages of in-situ ablation with minimal discomfort to the patient and deformity of the breast. More importantly, it demonstrates the absence of any adverse effect on health and survival of the patient during this intermediate period of follow-up.
Empowering the creative user (2013)

This paper presents the design, implementation, and validation of a novel system that supports streaming and playout of personalized, multi-path, nonlinear video. In contrast to regular video, in which the file content is played sequentially, our design allows multiple nonlinear video sequences of the underlying (linear) video to be stitched together and played in any personalized order, and clients can be provided multiple path choices. The design combines the ideas of HTTP-based adaptive streaming (HAS) and multi-path nonlinear video. Personalization of the content is achieved with the use of a customized metafile, which is downloaded separately from the underlying media and the manifest file that defines the HAS structure. An extension to the user interface allows path choices to be presented to and made by the user. Novel buffer management and prefetching policies are used to ensure seamless uninterrupted playback regardless of client path choices, even under scenarios in which clients defer their choices until the last possible moment. Our solution allows creative home users to easily create their own multi-path nonlinear video, opening the door to an endless possibility of new opportunities and media forms.
SDN: Evolution and Opportunities in the Development IoT Applications (2014)

The exponential growth of devices connected to the network has resulted in the development of new IoT applications and on-line services. However, these advances are limited by the rigidity of the current network infrastructure, in which the administrator has to implement high-level network policies adapting and configuring protocols manually and usually through a command line interface (CLI). At this point, Software-Defined Networking (SDN) appears as a viable alternative network architecture that allows for programming the network and opening the possibility of creating new services and more efficient applications to cover the actual requirements. In this paper, we describe this new technology and analyze its opportunities in the development of IoT applications. Similarly, we present the first applications and projects based on this technology. Finally, we discuss the issues and challenges in its implementation.
