Dielectric properties and partial discharge endurance of polypropylene-silica nanocomposite (2010)

This paper presents the results of the dielectric properties and partial discharge endurance measurements conducted on polypropylene (PP)-silica nanocomposite. The material compounds were analyzed with micro-Raman spectroscopy, X-ray tomography and transmission electron microscopy (TEM). ac and dc breakdown strength of the materials was measured. Dielectric response, capacitance and loss factor of the film samples were measured as a function of temperature and frequency. Partial discharge (PD) endurance of the reference PP and PP Silica nanocomposite was studied as a function of ac voltage. Material surfaces were analyzed after PD stress with optical microscopy. All dielectric measurements were done for oriented thin films with a thickness of 11-23 μm. The results were analyzed statistically to determine the effects of the additive on the properties of PP. The paper discusses the potential of PP Silica nanocomposite with a view to high voltage applications, especially power capacitors.
Measurement of Coherent Undulator Radiation of Compact Terahertz Radiation Source at Kyoto University (2017)

An accelerator based compact terahertz radiation source has been successfully developed at Institute of Advanced Energy, Kyoto University. The system is very compact with the total length of 3.7 m. The radiations are generated by injecting a short electron bunch to a 0.7 m long 10-period planar Halbach type undulator. The radiations have a high degree of phase coherence or called coherent undulator radiation. The frequencies are tunable in the range from 0.17 to 0.55 THz. The electron source is a 1.6 cells BNL type photocathode RF gun which provides the beam with energy of 4.6 MeV.
Attacks on time-of-flight distance bounding channels (2008)

Cryptographic distance-bounding protocols verify the proximity of two parties by timing a challenge-response exchange. Such protocols rely on the underlying communication channel for accurate and fraud-resistant round- trip-time measurements, therefore the channel's exact timing properties and low-level implementation details become security critical. We practically implement 'late-commit' attacks, against two commercial radio receivers used in RFID and sensor networks, that exploit the latency in the modulation and decoding stages. These allow the attacker to extend the distance to the verifier by several kilometers. We also discuss how 'overclocking' a receiver can make a prover respond early. We practically implement this attack against an ISO 14443A RFID token and manage to get a response 10 µs earlier than normal. We conclude that conventional RF channels can be problematic for secure distance-bounding implementations and discuss the merits and weaknesses of special distance-bounding channels that have been proposed for RFID applications.
FcgRIIIA (CD16)-expressing monocytes mediate the depletion of tumor-infiltrating Tregs via Ipilimumab-dependent ADCC in melanoma patients (2014)

Meeting abstracts Enhancing immune responses with immune-modulatory monoclonal antibodies (mAbs) directed to inhibitory immune-receptors is a promising modality in cancer therapy. Clinical efficacy has been demonstrated with antibodies blocking inhibitory immune checkpoints such as CTLA-4 or PD-1/
On modeling energy-security trade-offs for distributed monitoring in wireless ad hoc networks (2008)

In this paper, we propose a game theoretic framework for distributed intrusion detection in ad hoc networks. The proposed models capture the energy-security tradeoffs for individual monitoring and propose an energy efficient design for distributed monitoring, with probabilistic guarantees for the achieved security level in the network.
Chemistry of the Interfaces of an Electric Water Heater: Implications from an Input-Output Analysis (2010)

Abstract In a case study, this paper responds to increasing public interest in water quality issues by investigating chemical changes as water passes through a domestic water hot water system. Elemental changes were measured by simultaneous analysis of the incoming and outgoing water streams and the deposited sediment from an electric water heater tank. The results may alter some long-held beliefs. The collected and dried sediment from the tank was analyzed for thirty common elements by inductively coupled plasma and atomic absorption techniques. Of the 25 elements found, the dominant seven in order of concentration were magnesium, aluminum, copper, zinc, manganese, iron, and sodium, as well as some surprising traces of other elements. The cold water input and the heated output were also analyzed for thirteen measurable elements. In the heated water output, magnesium had a massive 151% increase in concentration, followed by much more modest increases shown by arsenic, calcium, lead, potassium, silicon, and strontium. None of these mass balance changes compromised the potability of the water. The six elements, aluminum, boron, copper, iron, manganese, and sodium, showed decreases in aqueous concentrations on heating, thereby improving the water quality.
A Comprehensive Program to Reduce Rates of Hospital-Acquired Pressure Ulcers in a System of Community Hospitals (2015)

Driven by the combination of a repository of evidence-based tools and best practices, readily available data on PrU rates, and local flexibility with processes, the Reducing Hospital Acquired-PrUs Program represents the successful operationalization of improvement in a wide variety of facilities.
Functional Equivalence of Monomeric and Dimeric Forms of Purified Acetylcholine Receptors from Torpedo californica in Reconstituted Lipid Vesicles (1980)

Acetylcholine receptors from Torpedo californica electric organ were solubilized and purified under conditions which prevent inactivation of the agonist-regulated cation channels. The dimer form of the receptors was preserved during purification. Treatment with reducing agents converted dimers into monomers. Receptor monomers and dimers were separately reconstituted into soybean lipid vesicles by the cholate dialysis technique. Reconstituted monomers and dimers were functionally equivalent with respect to their carbamylcholine-induced dose-dependent uptake of 22Na+, the total flux of 22Na+ per receptor during the permeability response, and the occurrence of desensitization. Evidence against non-covalent association of monomers to produce dimeric functional units was obtained using glutaraldehyde as a crosslinking agent. These results show that both the acetylcholine-binding sites and the agonist-regulated cation-specific channel are contained within the α2βγδ subunit structure of the acetylcholine receptor monomer.
The effect of confinements on phase behaviour of the mixture possessing smectic CAphase (2000)

Abstract We present experimental data on the phase behaviour of a mixture possessing SmCA* phase, which show that the balance between ferroelectric and antiferroelectric states is very mobile and can be shifted in favour of ferroelectric phase by weak external forces due to aligning surfaces.
Longing for Ligand: Hedgehog, Patched, and Cell Death (2003)

The hedgehog signaling pathway controls crucial events during development. In a Perspective,
 Guerrero and Ruiz i Altaba
 discuss new work (
 Thibert
 et al .) that identifies the Ptc1 receptor for Sonic hedgehog as a crucial modulator of programmed cell death during development of the chick neural tube. Ptc1 joins a cadre of other receptors, called ligand dependence receptors, that induce the programmed cell death of cells bearing them if they remain unoccupied by ligand.
Studies on Alkylated Furan Derivatives. III (1960)

During the preparation of 5-alkylated and 5, N-dialkylated 2-furamides, introduction of alkyl group into α-position of the ring was effected by acylation of the furan ring and reduction of carbonyl by the Wolff-Kishner reduction. None of the compounds prepared had strong antitubercular action but 5-alkylated compounds showed strong antifungal activity against Trichophyton, Microsporum and Aspergillus spp.
A combined experimental and theoretical study on the side ingress of water into barrier adhesives for organic electronics applications (2014)

This paper presents a thorough experimental and theoretical analysis of a model system for the mechanism of cathode degradation in OLED and OPV devices due to lateral side ingress of water vapour into laminated thin film barrier structures. The experimental procedure allows for full quantitative control over layer dimensions of the laminate, as well as the buffer zone width of the lamination adhesive. The optical calcium test is used to monitor side ingress of water vapour both at ambient (20 °C/50% RH) and accelerated (60 °C/90% RH) weathering conditions. Three curable adhesive formulations with sorption and diffusion constants respectively in the range 0.03 < S < 0.4 mol m−3 Pa−1 and 5 × 10−14 < D < 2 × 10−12 m2 s−1 are benchmarked with respect to their capacity to retard ingress and calcium oxidation. A time-resolved 1D semi-analytical model is developed that simulates ingress and degradation. Extensive simulations involving a wide range of values for geometric, material-, and climate-related parameters allow for the derivation of scaling relations for the oxidation front displacement and break-through time as a function of the sorptivity and diffusivity of the lamination adhesive. It is demonstrated that the oxidation front position behaves as: ∼(DS)1/2 and ∼D1/2Sn, n < 1/2 under permeation- and diffusion-controlled conditions respectively, whereas in those same regimes the break-through time behaves as: ∼d02D−1S−0.45 and ∼d02D−1Sn, −0.45 < n < 0, d0 indicating the width of the adhesive buffer zone. These insights demonstrate the fully predictive nature of the model and evidence its usefulness for both material development and barrier design for organic electronics applications.
Flood Monitoring and Early Warning System: The Integration of Inundated Areas Extraction Tool (2010)

This paper examines a satellite images processing system with a mechanism for detecting the inundated areas and supporting to flood monitoring and warning. The interoperable handling system is established in order to freely access the inundated areas with no defensive barrier by the software operability limitations. The ultimate goal of this effort is to bring awareness of the potentially catastrophic occurrence that can be pre-detected and prevented altogether. The development of the algorithm to extract the inundated areas and convey urgent messages during the time of crisis is performed on a user-friendly web based interface. A careful examination of various locations on LANDSAT images yields promising results. Although the size of images is limited by the available bandwidth of the web based application, processing at 4000*4000*3 bands per image takes approximately 3 minutes. This is a significant improvement over currently available methods for inundated detection systems. Additional benefits include software operation cost saving, and reduction of operational expenses and time. Furthermore, it does not require technical expertise to predict the rise of flood disasters.
Calculation of interference levels due to rain scatter on high-altitude platform links (2001)

The possibility of using high-altitude platforms (HAPs) in telecommunications, traffic monitoring and environmental remote sensing has attracted a lot of interest. The main reasons for this are the low implementation and deployment costs and attractive propagation characteristics of HAPs. Compared to satellites, HAPs are highly advantageous in terms of free space path loss, time delay, and ease and cost of deployment. HeliNet is a project supported by the European Union, involving several industrial and academic partners, including the University of York, with the aim of examining the feasibility of an airborne platform to support telecommunications, traffic monitoring and remote sensing applications. The main responsibility of the University of York is to assess the potential of HAPs to support broadband telecommunication services. This study explores degradation due to interference from rain scattering, which may be much worse than in LEO satellite systems in which the cells are up to 10 times larger. This is because, for a cell diameter d, in general the carrier power has a d/sup -2/ dependence while the power received by the scattering process has a d/sup -4/ dependence. The implications of this interference in system design are discussed.
Effects of low and hyper Dk rigid gas permeable contact lenses on Bcl-2 expression and apoptosis in the rabbit corneal epithelium. (2001)

Bcl-2 protein seems to play an important role in the regulation of apoptotic cell shedding in the normal rabbit corneal epithelium. The identical staining pattern was seen in previous studies of the normal human cornea. RGP contact lens wear, however, appears to block the changes in Bcl-2 protein prior to apoptotic surface cell shedding, suggesting a lens-related anti-apoptotic effect. Taken together, these findings may explain why contact lens wear reduces surface cell exfoliation as previously reported in human studies.
KERNEL-BASED TOPOGRAPHIC MAP FO R MAT1 0 N AC H I EVE D WITH N 0 R MA L I Z ED (2002)

A new learning algorithm for kernel-based topographic map formation is introduced. The kernels are Gaussians, and their centers and ranges individually adapted so as to yield an equiprobabilistic topographic map. The converged map also generates a heteroscedastic Gaussian mixture model of the input density. This is verified for both synthetic and real-world examples, and compared with other algorithms for kernel-based topographic map formation.
The Inhibitor of Apoptosis (IAPs) in Adaptive Response to Cellular Stress (2012)

Cells are constantly exposed to endogenous and exogenous cellular injuries. They cope with stressful stimuli by adapting their metabolism and activating various "guardian molecules." These pro-survival factors protect essential cell constituents, prevent cell death, and possibly repair cellular damages. The Inhibitor of Apoptosis (IAPs) proteins display both anti-apoptotic and pro-survival properties and their expression can be induced by a variety of cellular stress such as hypoxia, endoplasmic reticular stress and DNA damage. Thus, IAPs can confer tolerance to cellular stress. This review presents the anti-apoptotic and survival functions of IAPs and their role in the adaptive response to cellular stress. The involvement of IAPs in human physiology and diseases in connection with a breakdown of cellular homeostasis will be discussed.
Enhanced Current Collection in 1.7 eV GaInAsP Solar Cells Grown on GaAs by Metalorganic Vapor Phase Epitaxy (2017)

Quaternary GaInAsP solar cells with a bandgap of ~1.7 eV offer an attractive Al-free alternative to AlGaAs solar cells for integration in next generation of III-V multijunction solar cells with five or more junctions. Development of a high quality 1.7 eV solar cell is also highly sought for III-V/Si tandem solar cells. In this work, we systematically investigate the impact of varying base thicknesses and doping concentrations on the carrier collection and performance of 1.7 eV GaInAsP solar cells. The photoresponse of these cells is found to be very sensitive to p-type zinc doping concentration in the base layer. Prototype 1.7 eV GaInAsP n-i-p solar cell designs are demonstrated that leverage enhanced depletion width as an effective method to achieve peak quantum efficiency exceeding 90%. We also show the importance of optimal i-layer thickness as a critical parameter to reduce the drop in fill-factor (FF) due to field-aided collection. Furthermore, we demonstrate substantial improvement in the cell performance when the GaInAsP base layer is grown at 650 °C instead of 600 °C. The best GaInAsP solar cell (Eg ~ 1.65 eV) in this study achieved JSC of 21.1 mA/cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , VOC of 1.18 V, FF of 83.8%, and an efficiency of 20.8 ± 1% under AM1.5D spectrum (21.5 ± 1% under AM1.5G spectrum). These results highlight the potential of Al-free GaInAsP solar cells for integration in the next generation of III-V multijunction solar cells.
Design and Analysis of NB QC-LDPC Codes Over Small Alphabets (2022)

We propose a novel approach to optimization of irregular nonbinary (NB) quasi-cyclic (QC)-LDPC codes over small alphabets. In this approach, first, the base parity-check matrices are constructed by a simulated annealing method, and then these matrices are labeled by the field elements while maximizing the so- called generalized girth of the Tanner graph. In order to analyze the performance of the constructed irregular NB LDPC codes, a new ensemble of irregular NB LDPC codes over the extensions of the binary Galois field is introduced. A finite-length random coding bound on the error probability of the maximum-likelihood (ML) decoding over the binary phase shift keying (BPSK) input AWGN channel for the new code ensemble is derived. The frame error rate (FER) performance of the sum-product belief-propagation (BP) decoding of the constructed NB QC-LDPC block codes is compared to that of both the optimized binary QC-LDPC block codes in the 5G standard and the best known NB QC-LDPC codes as well as to the derived random coding bound on the ML decoding error probability. It is shown that the obtained bound predicts the behavior of BP decoding performance of practical NB QC-LDPC codes more accurately than the BP decoding thresholds do.

Integrating an Image-Guided Robot with Intraoperative MRI (2008)

Microsurgical techniques, together with the introduction of intraoperative magnetic resonance imaging (MRI), established the need and the environment for the integration of robotics with surgery. In this article, we summarize our experience with intraoperative MRI on 781 neurosurgical patients. Intraoperative MRI demonstrated unsuspected residual pathology in up to 20% of patients. To take full advantage of the imaging environment, an magnetic resonance (MR)-compatible image-guided robot capable of both microsurgery and stereotaxy was designed and constructed. Unique features of the system include the use of non-ferromagnetic materials, an end effector that actuates standard surgical instrumentation, automated tool exchange, and haptic feedback.
Results of computed tomography-based computer-assisted stereotactic resection of metastatic intracranial tumors (1988)

Forty-four patients underwent 45 computer-assisted stereotactic resections of intracranial metastases from various centrally located and deep-seated regions using methods described in this report and elsewhere. Gross total removal was achieved in all cases. There was no postoperative mortality (within 30 days). Postoperative neurological examinations revealed that: (a) of 26 who presented with preoperative neurological deficits, 13 were normal postoperatively, 7 were improved, 3 were unchanged, and 3 were worse; (b) 5 of 5 patients who had increased intracranial pressure preoperatively were normal postoperatively; and (c) 3 of 3 patients who had increased intracranial pressure and neurological deficit preoperatively were neurologically normal postoperatively. Nine of 10 patients who were neurologically normal preoperatively were normal postoperatively, and the other had transient upper extremity weakness after resection of a lesion in the contralateral motor strip. The 1-year survival in this group of patients was 62.5%. No local recurrence was noted in any patient. Computer-assisted stereotactic resection permits accurate localization of metastatic lesions and gross total resection from difficult locations with acceptable levels of morbidity.

Test data for the full array will be presented in the final paper.
Outdoor navigation using natural landmarks by teaching-playback scheme (2002)

In this paper, we report the outdoor navigation of an autonomous and self-contained mobile robot using the perceived route map (PRM) generated through human assisted route teaching. The PRM includes the path from the start to the goal taught by the operator and landmark information are automatically generated by the robot itself. The target environment is a paved or tiled pedestrian walkway. The pedestrian walkway can be assumed to be a two dimensional plane along with a wall, a hedge or a tree, etc., which can be utilized as landmarks for estimating the robot position. The robot is assumed to have sensors to detect landmarks and obstacles. A walking person or bicycle is assumed to be a moving obstacle.
A new design of an air core transformer for Electric Vehicle On-Board Charger (2020)

This paper compares two geometries of air core transformer, relevant for high frequency converters and high power densities: One logical toroidal, one innovative cylindrical. The manufacturing, the coupling parameter, the volume, and the flux leakage are examined in these topologies. The efficiency symbolizes a crucial parameter on power electronics, and a trade-off must ever be optimized between size and power. The proposed innovative structure permits to strongly increase the converter power density for an identical efficiency.
Immunologic memory with no detectable bactericidal antibody response to a first dose of meningococcal serogroup C conjugate vaccine at four years (2003)

Fourteen children with no detectable bactericidal antibody response to a first dose of meningococcal C conjugate vaccine at 4 years of age were given a booster dose of the same vaccine 2 years later. A rapid 1000-fold rise in postimmunization bactericidal antibody titers, a measured either 7 or 14 days later, suggested previous immunologic priming.
Speeding up parallel decoding of LZ compressed text on the PRAM EREW (2002)

While sliding window (LZ1) compression can be parallelized efficiently, the LZ2 compression method seems hardly parallelizable since some related heuristics are known to be P-complete. In spite of such negative result, there are parallel decoders which run in O(log/sup 2/ n) time with O(n/log n) processors on the PRAM EREW where n is the length of the output string, as for LZ1 decompression. We show a faster parallel decoding algorithm which runs on the PRAM EREW in O(log n) time with O(n) processors for text compressed by a standard implementation of the LZ2 algorithm (next character heuristic). We observe that LZ1 parallel decoders also can have such speed up. Moreover, we address a different implementation of LZ2 compression called identity heuristic. In this case, decoding on the PRAM EREW takes O(log n log log n) time with O(n/log n) processors with the realistic assumption that the length of the dictionary elements is logarithmic.
