MAC ID Spoofing-Resistant Radio Fingerprinting (2019)

We explore the resistance of deep learning methods for radio fingerprinting to MAC ID spoofing. We demonstrate that classifying transmission slices enables classification of a transmission with a fixed-length input deep classifier, enhances shift-invariance, and, most importantly, makes the classifier resistant to MAC ID spoofing. This is a consequence of the fact that the classifier does not learn to use the MAC ID to classifying among transmissions, but relies on other inherent discriminating signals, e.g., device imperfections. We demonstrate this via experiments on transmissions generated using two protocols, namely, WiFi and ADS-B.
Influence of age as a factor in the outcome of gestational trophoblastic neoplasia. (2008)

Patient age may not be a risk factor for gestational trophoblastic neoplasia. With birth rates in women > 40 years and maternal age at first pregnancy significantly increasing in the United Kingdom, it is important to improve our understanding of the relationship between GTN and maternal age.
Pathogenicity of the Novel A/H7N9 Influenza Virus in Mice (2013)

An H7N9 virus isolate causing fatal human disease was found to be more pathogenic for mice than other avian H9N2 or H7N9 viruses but less pathogenic than the highly pathogenic avian influenza virus (HPAI) H5N1. Similarly, the ability of Sh2/H7N9 to elicit proinflammatory cytokines in the lung and serum of mice was intermediate to ck/H9N2 and dk/H7N9 on the one hand and HPAI H5N1 on the other. These findings accord with the observed epidemiology in humans, in whom, as with seasonal influenza viruses, H7N9 viruses cause severe disease predominantly in older persons while HPAI H5N1 can cause severe respiratory disease and death in children and young adults.
SNR‐enhanced diffusion MRI with structure‐preserving low‐rank denoising in reproducing kernel Hilbert spaces (2021)

Nonlinear redundancy of the dMRI signal can be exploited with KPCA, which allows superior noise reduction/SNR improvements than the MPPCA method, without loss of signal information.
Unique Requirements for Reactivation of Virus-Specific Memory B Lymphocytes (2010)

Memory B cells (MBCs) are rapidly activated upon Ag re-exposure in vivo, but the precise requirements for this process are still elusive. To address these requirements, T cell-independent reactivation of MBCs against virus-like particles was analyzed. As few as 25 MBCs are sufficient for a measurable Ab response after adoptive transfer. We found that MBCs were reactivated upon antigenic challenge to normal levels after depletion of macrophages, CD11c(+) dendritic cells, and matured follicular dendritic cells. Furthermore, MBC responses were possible in TNF/lymphotoxin α double-deficient mice after partial normalization of lymphoid architecture by means of long-term reconstitution with wild-type bone marrow. Activation did not occur when chimeric mice, which still lack all lymph nodes and Peyer's patches, were splenectomized prior to MBC transfer. Together with our finding that MBC responses are weak when Ag was administered within minutes after adoptive MBC transfer, these results strongly suggest that MBCs have to occupy specific niches within secondary lymphoid tissue to become fully Ag-responsive. We provide clear evidence that MBCs are not preferentially resident within the splenic marginal zones and show that impaired homing to lymphoid follicles resulted in significantly diminished activation, suggesting that reactivation of MBCs occurred inside lymphoid follicles. Furthermore, comparison of virus-specific MBC T cell-independent reactivation versus primary T cell-independent type II B cell activation revealed unique requirements of MBC activation.

Memory-bounded bidirectional search (1994)

Previous approaches to bidirectional search require exponential space, and they are either less efficient than unidirectional search for finding optimal solutions, or they cannot even find such solutions for difficult problems. Based on a memory-bounded unidirectional algorithm for trees (SMA*), we developed a graph search extension, and we used it to construct a very efficient memory-bounded bidirectional algorithm. This bidirectional algorithm can be run for difficult problems with bounded memory. In addition, it is much more efficient than the corresponding unidirectional search algorithm also for finding optimal solutions to difficult problems. In summary, bidirectional search appears to be the best approach to solving difficult problems, and this indicates the extreme usefulness of a paradigm that was neglected for long.

A current‐activated sediment trap (1994)

A current‐activated sediment trap is described that collects particles based on preselected current speed and direction criteria. The collector incorporates a steep‐walled funnel, a motor‐driven carousel with sample cups, an absolute optical shaft encoder, and an acoustic current meter. A field trial of the trap was carried out in a shallow marine embayment over 3 d where it correctly positioned cups in response to tidal changes in current speed and direction. Particle organic content and sedimentation rates calculated over hourly intervals were similar to measurements with a standard sequential sampling trap over several hours when the two traps were deployed simultaneously.
Modelling lateral beam quality variations in pencil kernel based photon dose calculations (2006)

Standard treatment machines for external radiotherapy are designed to yield flat dose distributions at a representative treatment depth. The common method to reach this goal is to use a flattening filter to decrease the fluence in the centre of the beam. A side effect of this filtering is that the average energy of the beam is generally lower at a distance from the central axis, a phenomenon commonly referred to as off-axis softening. The off-axis softening results in a relative change in beam quality that is almost independent of machine brand and model. Central axis dose calculations using pencil beam kernels show no drastic loss in accuracy when the off-axis beam quality variations are neglected. However, for dose calculated at off-axis positions the effect should be considered, otherwise errors of several per cent can be introduced. This work proposes a method to explicitly include the effect of off-axis softening in pencil kernel based photon dose calculations for arbitrary positions in a radiation field. Variations of pencil kernel values are modelled through a generic relation between half value layer (HVL) thickness and off-axis position for standard treatment machines. The pencil kernel integration for dose calculation is performed through sampling of energy fluence and beam quality in sectors of concentric circles around the calculation point. The method is fully based on generic data and therefore does not require any specific measurements for characterization of the off-axis softening effect, provided that the machine performance is in agreement with the assumed HVL variations. The model is verified versus profile measurements at different depths and through a model self-consistency check, using the dose calculation model to estimate HVL values at off-axis positions. A comparison between calculated and measured profiles at different depths showed a maximum relative error of 4% without explicit modelling of off-axis softening. The maximum relative error was reduced to 1% when the off-axis softening was accounted for in the calculations.
Application of Composite Dictionary Multi-Atom Matching in Gear Fault Diagnosis (2011)

The sparse decomposition based on matching pursuit is an adaptive sparse expression method for signals. This paper proposes an idea concerning a composite dictionary multi-atom matching decomposition and reconstruction algorithm, and the introduction of threshold de-noising in the reconstruction algorithm. Based on the structural characteristics of gear fault signals, a composite dictionary combining the impulse time-frequency dictionary and the Fourier dictionary was constituted, and a genetic algorithm was applied to search for the best matching atom. The analysis results of gear fault simulation signals indicated the effectiveness of the hard threshold, and the impulse or harmonic characteristic components could be separately extracted. Meanwhile, the robustness of the composite dictionary multi-atom matching algorithm at different noise levels was investigated. Aiming at the effects of data lengths on the calculation efficiency of the algorithm, an improved segmented decomposition and reconstruction algorithm was proposed, and the calculation efficiency of the decomposition algorithm was significantly enhanced. In addition it is shown that the multi-atom matching algorithm was superior to the single-atom matching algorithm in both calculation efficiency and algorithm robustness. Finally, the above algorithm was applied to gear fault engineering signals, and achieved good results.
Effect of heat treatments on microstructural and mechanical characteristics of dissimilar friction stir welded 2198/2024 aluminum alloys (2021)

The 3rd generation of aluminum–lithium (Al–Li) alloys provides a desirable combination of high mechanical properties and low density compared to their traditional counterparts, exempt of lithium. Therefore, providing a reliable joint between new and conventional aluminum alloys is crucial for making hybrid structures. The present study focuses on improving the mechanical properties of dissimilar AA2198/AA2024 joints using different heat treatments before and after welding. Tensile tests paired with digital image correlation (DIC) techniques and micro-hardness maps were performed to document the macro-scale and local mechanical behavior of the joints. As-welded joints demonstrated a similar yield strength, 30% lower than that of the base metals in T3 and T8 metallurgical states. As-welded joints failed at the AA2198 side in the heat affected zone (HAZ), parallel to the thermo-mechanically affected zone (TMAZ), region experiencing intense strain concentration and minimal hardness values. Post welding-heat treatments (PWHT) was found to successfully strengthen HAZ on the AA2198 side, without abnormal grain growth in the nugget and impairing the hardness properties on AA2024 side. This improvement in local mechanical properties on the AA2198 side was related to the re-precipitation of dissolved T1 (Al2CuLi) and θ (Al2Cu) during welding as characterized by differential scanning calorimetry (DSC) and microscopy analyses. However, PWHT joint variants demonstrated a reduction in total elongation and ultimate tensile strength due to intense strain localization on the AA2024 retreating side compared to a much more homogeneous strain distribution in the as-welded joints.
The national cancer data base report on prostate cancer (1995)

This information provides national points of reference against which individual hospital performance can be compared and should be particularly helpful to cancer committees, tumor boards, and cancer registrars for the monitoring and evaluation of prostate cancer management in hospital cancer programs. Not all segments of the population-at-risk are benefiting from earlier detection of prostate cancer. Improvements in early detection have important consequences for treatment patterns, allowing the increased use of curative surgical or radiotherapeutic treatment.
Ultrahigh-Sensitive Tin-Oxide Microsensors for H&lt;tex&gt;$_2$&lt;/tex&gt;S Detection (2004)

Ultrahigh-sensitivity SnO/sub 2/-CuO sensors were fabricated on Si(100) substrates for detection of low concentrations of hydrogen sulfide. The sensing material was spin coated over platinum electrodes with a thickness of 300 nm applying a sol-gel process. The SnO/sub 2/-based sensors doped with copper oxide were prepared by adding various amounts of Cu(NO/sub 3/)/sub 2/.3H/sub 2/O to a sol suspension. Conductivity measurements of the sensors annealed at different temperatures have been carried out in dry air and in the presence of 100 ppb to 10-ppm H/sub 2/S. The nanocrystalline SnO/sub 2/-CuO thin films showed excellent sensing characteristics upon exposure to low concentrations of H/sub 2/S below 1 ppm. The 5% CuO-doped sensor having an average grain size of 20 nm exhibits a high sensitivity of 2.15/spl times/10/sup 6/ (R/sub a//R/sub g/) for 10-ppm H/sub 2/S at a temperature of 85/spl deg/C. By raising the operating temperature to 170/spl deg/C, a high sensitivity of /spl sim/10/sup 5/ is measured and response and recovery times drop to less than 2 min and 15 s, respectively. Selectivity of the sensing material was studied toward various concentrations of CO, CH/sub 4/, H/sub 2/, and ethanol. SEM, XRD, and TEM analyses were used to investigate surface morphology and crystallinity of SnO/sub 2/ films.
Heavier Alkaline Earth Catalysts for the Intermolecular Hydroamination of Vinylarenes, Dienes, and Alkynes (2011)

The heavier group 2 complexes [M{N(SiMe(3))(2)}(2)](2)(1, M = Ca; 2, M = Sr) and [M{CH(SiMe(3))(2)}(2)(THF)(2)] (3, M = Ca; 4, M = Sr) are shown to be effective precatalysts for the intermolecular hydroamination of vinyl arenes and dienes under mild conditions. Initial studies revealed that the amide precatalysts, 1 and 2, while compromised in terms of absolute activity by a tendency toward transaminative behavior, offer greater stability toward polymerization/oligomerization side reactions. In every case the strontium species, 2 and 4, were found to outperform their calcium congeners. Reactions of piperidine with para-substituted styrenes are indicative of rate-determining alkene insertion in the catalytic cycle while the ease of addition of secondary cyclic amines was found to be dependent on ring size and reasoned to be a consequence of varying amine nucleophilicity. Hydroamination of conjugated dienes yielded isomeric products via η(3)-allyl intermediates and their relative distributions were explained through stereoelectronic considerations. The ability to carry out the hydroamination of internal alkynes was found to be dramatically dependent upon the identity of the alkyne substituents while reactions employing terminal alkynes resulted in the precipitation of insoluble and unreactive group 2 acetylides. The rate law for styrene hydroamination with piperidine catalyzed by [Sr{N(SiMe(3))(2)}(2)](2) was deduced to be first order in [amine] and [alkene] and second order in [catalyst], while large kinetic isotope effects and group 2 element-dependent ΔS(++) values implicated the formation of an amine-assisted rate-determining alkene insertion transition state in which there is a considerable entropic advantage associated with use of the larger strontium center.
TEMPERATURE-GRADIENT INCUBATOR FOR DETERMINING THE TEMPERATURE RANGE OF GROWTH OF MICROORGANISMS (1963)

Elliott, R. Paul (U.S. Department of Agriculture, Albany, Calif.). Temperature-gradient incubator for determining the temperature range of growth of microorganisms. J. Bacteriol. 85:889-894. 1963.-The temperature-gradient incubator consists of an aluminum bar with troughs for media, with controlled temperatures at each end, and with insulation to prevent heat transfer. The resulting linear temperature gradient provides a means for determining minimal or maximal growth temperatures of microorganisms in any desired range and at any desired gradient. The operation of the incubator is unaffected by line-voltage variations or by ambient temperature. Media do not dehydrate seriously even during prolonged periods of operation. The incubator can be used to determine water activity of media by an adjustment to permit partial freezing. Either thermocouples or thermistors may be used to measure temperatures.
Variable Impedance Bilateral Control for Object Discrimination in Microsurgery (2008)

Recently, laparoscopic microsurgery using master-slave system has been gotten a lot of attention. However, as the current system implemented is not capable of presenting haptic sense to operators, it places a large burden on operators. In addition, it is also necessary to enlarge the kinesthetic sense so that the operators can perceive small reactive force against a patient's body. The reactive force on the slave is minute in microsurgery. Therefore, it is necessary to expand the reactive force recognize the object. However, when the reactive force is expanded by a constant ratio, the distinction of the object becomes difficult. In this paper, in order to solve this problem, we propose variable impedance control. The bilateral control consists of contact mode and free motion mode. In the free motion mode, a constant impedance model is used. In the contact mode, estimate the impedance of the object and vary the control model. As a result, the characteristic of the object is clearly reproduced on the master, and the distinction of the object can be facilitated.
ABT‐127, a novel Dopamine D3 Receptor Antagonist: Cardiovascular Profile in the Anesthetized Dog (2006)

ABT-127 is a novel and orally efficacious dopamine D3-selective antagonist targeted for the treatment of schizophrenia (pre-clinical efficacious Cmax in a rat model of social interaction = 50 ng/mL) and is hypothesized to produce fewer cardiovascular effects than classical or atypical antipsychotics that target multiple receptors. Thus, the cardiovascular profile of ABT-127 was delineated during three 30-min escalating infusions in the pentobarbital anesthetized beagle dog. In low- and high-dose studies (n=6–8/group) ABT-127 produced only a modest increase in heart rate (9 ± 3%) at 2.67 μg/mL (53-fold the Cmax) and produced no effect on blood pressure, cardiac output, or systemic vascular resistance at the highest concentrations tested (3.36 μg/mL; 67-fold). Moreover, ABT-127 produced no effect on left ventricular dP/dtmax at concentrations as high as 1.29 μg/mL (26-fold); at higher concentrations (2.67 to 3.36 μg/mL) dP/dtmax fell to −13 ± 3 and −21 ± 2% below baseline. ABT-127 produced no increase in the QT-interval corrected for changes in heart rate (QTc) at any concentration tested (up to 3.36 μg/mL; 67-fold the Cmax). In contrast, both classical and atypical antipsychotics have been shown to produce dose-dependent hemodynamic and electrocardiographic effects (increases in QTc) in the same model and in patients. These data suggest that ABT-127 has a relatively benign cardiovascular profile and produces no increases in QTc and only modest hemodynamic effects at the highest concentration tested (3.36 μg/mL or 67-fold the pre-clinical efficacious Cmax).
Deployment of a grid-based medical imaging application. (2005)

The MammoGrid project has deployed its Service-Oriented Architecture (SOA)-based Grid application in a real environment comprising actual participating hospitals. The resultant setup is currently being exploited to conduct rigorous in-house tests in the first phase before handing over the setup to the actual clinicians to get their feedback. This paper elaborates the deployment details and the experiences acquired during this phase of the project. Finally the strategy regarding migration to an upcoming middleware from EGEE project will be described. This paper concludes by highlighting some of the potential areas of future work.
Miniaturised battery charger using piezoelectric transformers (2002)

Piezoelectric materials are a technology that in recent years have raised enormous interest for their possible use as power transformers. Their main features are high power densities, absence of electromagnetic noise and high voltage isolation capability. This paper presents the results obtained in a prototype of a miniaturized battery charger for mobile phones. Due to the reduced size of the piezoelectric transformers, the charger has been introduced in a plug type case, smaller than a matchbox.
Estimating time-varying DOA and Doppler shift in radar array processing (2000)

The authors consider the problem of retrieving information about space debris in low-Earth orbit by means of a radar system operating in a bi-static mode. More exactly, a pulse radar steers a beam in a prescribed region of space. When crossing the main lobe of the radar, a moving object will reflect energy towards a ground-based array of sensors. The signal is affected by Doppler shift, which is related to radial speed. Additionally, its direction-of-arrival (DOA), related to the orthoradial speed, will be time-varying. Maximum likelihood (ML) solutions to the problem of estimating both the Doppler shift and the time-varying DOA are proposed. Since the exact ML solution is computationally intensive, a simpler alternative is presented that relies on the extended invariance principle. The new method is shown to be simple as it only entails Fourier transforms and linear computations. Its performance is illustrated via numerical simulations.
Advancing rights for women: the role of litigation. (2006)

Litigation is becoming an increasingly attractive advocacy tool for human rights movements around the world. It has served as an effective strategy not only for reforming or enforcing laws that deny or protect basic human rights, but also for raising awareness of and mobilizing support for human rights issues. In this article, which is based on a presentation at a symposium session at the conference, Luisa Cabal focuses on a specific area within the realm of women's health and rights--the rights of HIV-positive women and girls, and in particular, violations they experience vis-à-vis access to health care--and discusses the potential for litigation to help raise awareness and advance efforts to protect and promote human rights in this area.
Dual-mode half-cut dielectric resonator filters (2009)

This paper shows that it is feasible to realize a quadruple-mode dielectric resonator. A half-cut of this resonator is then shown to support two modes. A new type of dual-mode dielectric resonator filters is introduced, using a cylindrical resonator cut in half along its axis. Center frequency control, intra/inter/input-coupling mechanisms, tuning, and spurious improvement methods are discussed, showing versatility of the proposed structure. Practical filter measurement results are presented which verify the proposed concept. The filter provides improvements in terms of size and mass reduction, in comparison with existing dual-mode dielectric resonator filters, while maintaining better spurious performance, with a small degradation in quality factor. It is a low-cost compact solution, suitable for both wireless and satellite applications.
