Enriching Basque Coreference Resolution System using Semantic Knowledge sources (2017)

In this paper we present a Basque coreference resolution system enriched with semantic knowledge. An error analysis carried out revealed the deficiencies that the system had in resolving coreference cases in which semantic or world knowledge is needed. We attempt to improve the deficiencies using two semantic knowledge sources, specifically Wikipedia and Word-Net.
The role of culture in women interacting with ICT (2009)

Gender and culture are two important social characteristics. Prior research has demonstrated that both of them have great impacts on users’ interaction with ICT. However, most studies examined these two factors in isolation. In this panel, we will identify raise broad awareness of the situations related to the role of culture in gender and ICT interaction, to identify some of the issues and challenges, to brainstorm potential research directions, and to identify potential interventions to narrow the gender gap in ICT interaction by examining situations in difference cultures.

X-ray powder data for Nd <sub>2</sub> Co <sub>14</sub> B, Pr <sub>2</sub> Co <sub>14</sub> B and Pr <sub>2</sub> Fe <sub>14</sub> B (1994)

The crystal structure data have been determined by X-ray diffraction for three rare earth magnetic materials, Nd 2 Co 14 B, Pr 2 Co 14 B, and Pr 2 Fe 14 B. The data were evaluated with several computer programs desingned for that purpose. The crystal structure for Nd 2 Co 14 B and Pr 2 Fe 14 D determined by X-ray diffraction agree with those obtained earlier by neutron diffraction.

Tele-impedance control of a variable stiffness prosthetic hand (2012)

We propose a variable stiffness prosthetic hand and present its surface electromyography (sEMG) interface for tele-impedance control. Such an interface, together with variable stiffness actuation (VSA), enables the amputee to modulate the impedance of the prosthetic limb to properly match the requirements of the task at hand, while performing activities of daily living. Both the desired position and stiffness of the hand are estimated through sEMG signals and these estimates are employed to control the VSA hand prosthesis. In particular, regulation of finger impedance is managed through the impedance measurements of the intact forearm; this control takes place naturally and automatically as the amputee interacts with the environment, while position of the hand prosthesis is regulated intentionally by the amputee through the estimated position of the thumb, extracted from sEMG signals of the dysfunctional agonistic and antagonistic thumb muscles that are embedded in the forearm. The proposed approach is advantageous, since the impedance regulation takes place naturally from task to task or during execution of a single task without requiring amputees' attention and diminishing their functional capability. Consequently, the proposed interface does not require long training periods or interfere with control of intact body segments, and provides amputee with easiness in use. The performance of the tele-impedance control of the VSA hand prosthesis is experimentally evaluated. Experimental results indicate that both position and stiffness can be adequately estimated using sEMG signals and regulated through VSA.
A real-time two-dimensional moment generating algorithm and its single chip implementation (1986)

We present a fast algorithm and its single chip VLSI implementation for generating moments of two-dimensional (2-D) digital images for real-time image processing applications. Using this algorithm, the number of multiplications for computing 16 moments of a 512 × 512 image is reduced by more than 5 orders of magnitude compared to the direct implementation; the number of additions is reduced by a factor of 4. This also makes the software implementation extremely fast. Using the chip, 16 moments μ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p,q</sup> (p = 0, 1, 2, 3, q = 0, 1, 2, 3) of a 512 × 512 8 bits/pixel image can be calculated in real time (i.e., 30 frames per second). Each moment value is computed as a 64- bit integer. The basic building block of the algorithm is a single-pole digital filter implemented with a simple accumulator. These filters are cascaded together in both horizontal and vertical directions in a highly regular structure which makes it very suitable for VLSI implementation. The chip has been implemented in 2.5 μ CMOS technology, it occupies 6100 μm × 6100 μm of silicon area. The chip can also be used as a general cell in a systolic architecture for implementing 2-D transforms having polynomial basis functions.
Halofuginone: a potent inhibitor of critical steps in angiogenesis progression (2000)

We have previously demonstrated that halofuginone, a low molecular weight quinazolinone alkaloid, is a potent inhibitor of collagen alpha1(I) and matrix metalloproteinase 2 (MMP-2) gene expression. Halofuginone also effectively suppresses tumor progression and metastasis in mice. These results together with the well-documented role of extracellular matrix (ECM) components and matrix degrading enzymes in formation of new blood vessels led us to investigate the effect of halofuginone on the angiogenic process. In a variety of experimental system, representing sequential events in the angiogenic cascade, halofuginone treatment resulted in profound inhibitory effect. Among these are the abrogation of endothelial cell MMP-2 expression and basement membrane invasion, capillary tube formation, and vascular sprouting, as well as deposition of subendothelial ECM. The most conclusive anti-angiogenic activity of halofuginone was demonstrated in vivo (mouse corneal micropocket assay) by showing a marked inhibition of basic fibroblast growth factor (bFGF) -induced neovascularization in response to systemic administration of halofuginone, either i.p. or in the diet. The ability of halofuginone to interfere with key events in neovascularization, together with its oral bioavailability and safe use as an anti-parasitic agent, make it a promising drug for further evaluation in the treatment of a wide range of diseases associated with pathological angiogenesis.
A feasibility and performance study of dependency inference (database design) (2003)

The feasibility of inferring functional dependencies from an example relation is investigated. The problem occurs in the context of automatic database design, when a tool is needed to assist the database designer in the process of specifying logical dependencies. The complexity of the dependency inference problem is inherently exponential. However, algorithms could be developed that perform well when the input relation has certain characteristics. Two such algorithms for dependency inference are implemented and optimized. An extensive set of experiments is presented, in which dependencies were inferred from example relations with different cardinalities, number of attributes, and degree of normalization. It is concluded that for practical example relations, an adequate implementation of a dependence inference function leads to acceptable interactive response times.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimized Led for Single-Fiber Optical Links. (1976)

The power coupled into an N.A. = 0.15, 90-micrometers core, multimode fiber from an edge-emitting, light-emitting diode has been significantly increased by the development of the narrow active region, double-heterojunction (DH) LED. As much as 0.8 mW has been coupled into a single fiber. The new diode structure results in a narrow (approx. 25 deg FWHM) emitted beam (in the direction perpendicular to the junction plane), and leads to optical coupling efficiencies 3 to 5 dB better than previously achieved. The radiance of the emitting facet is greatly increased, to over 1000 W/sq cm--sr, a factor of 10 greater than previously reported. The new structure also results in LEDs that can be modulated at high frequencies (150 MHz). Coupling from the narrow-active-region, DH diodes into the fiber is further enhanced, by about 3 dB, with the use of a microlens melted onto the fiber end. Overall coupling efficiencies of 9 to 11 dB are achieved. With the high modulation speed and coupled power of these diodes, material dispersion effects in the fiber, rather than signal power or diode speed, limit the usable distance-bandwidth product.

A prospective study of plasma hormone levels, nonhormonal factors, and development of benign prostatic hyperplasia (1995)

We assessed the relation of plasma hormone levels and nonhormonal factors with subsequent occurrence of surgical treatment for benign prostatic hyperplasia (BPH) among participants in the Physicians' Health Study. Frozen plasma samples, collected at the study onset, were available for 320 men who developed surgically treated BPH up to 9 years later and for 320 age-matched controls. Plasma testosterone (T), dihydrotestosterone (DHT), androstenedione, estradiol (E2), and estrone (E1) were measured for each case-control pair. In unadjusted analyses, none of the hormones or hormone ratios were associated with BPH; for example, for T and E2 the odds ratios (OR) comparing the highest quintile (Q5) with the lowest (Q1) were 0.74 (95% CI = 0.42, 1.30) and 1.07 (95% CI = 0.51, 2.22), respectively. However, in multivariate analyses controlling diastolic blood pressure, exercise, alcohol, E1, and DHT:T ratio, we observed a strong trend for increasing risk across quintiles for E2 (Q5 vs. Q1 OR = 3.56, P trend = 0.009), and a weak inverse trend for E1 (Q5 vs Q1 OR = 0.51, P trend = 0.07). The excess risk associated with E2 was confined to men with relatively low androgen levels. Three nonhormonal factors previously suspected as risk factors were independently associated with surgical BPH in these data. The OR for a 1-mm Hg difference in diastolic blood pressure was 1.04 (95% CI = 1.01, 1.07). Alcohol use and infrequent exercise were inversely associated with risk of BPH surgery; however, risk estimates were not consistent across categories of exercise and alcohol frequency. Our results indicate that normal variation in circulating androgen levels does not influence development of BPH, but that variation in estrogen levels might be important.
RF Mesh Systems for Smart Metering: System Architecture and Performance (2010)

This paper describes the system architecture and the performance evaluation of a Radio Frequency (RF) mesh based system for smart energy management applications in the Neighborhood Area Network (NAN). The RF mesh system presented in this paper leverages the Industrial, Scientific and Medical (ISM) band at 902-928 MHz and is based on frequency hopping spread spectrum (FHSS). The performance evaluation is based on a geographical model of the deployment scenario and implements geographical routing combined with appropriate radio propagation models. The results show that the system is able to handle Smart Metering communication traffic with a high reliability provided potential coverage gaps are properly filled with repeater nodes. The proposed methodology allows the identification of coverage gaps, which may cause bottlenecks in the network, prior to deployment and therefore supports efficient and reliable deployment and operation of the system.
Automatic detection of memory anti-patterns (2008)

In large distributed enterprise systems detection of memory problems can be a burdensome task. For understanding the memory related problems a catalog which documents memory anti-pattens is proposed. This paper also introduces our proposed prototype tool for the automatic detection of memory anti-patterns.
PAMS: Pattern Aware Memory System for embedded systems (2014)

In this paper, we propose a hardware mechanism for embedded multi-core memory system called Pattern Aware Memory System (PAMS). The PAMS supports static and dynamic data structures using descriptors and specialized memory and reduces area, cost, energy consumption and hit latency. When compared with a Baseline Memory System, the PAMS consumes between 3 and 9 times and 1.13 and 2.66 times less program memory for static and dynamic data structures respectively. The benchmarking applications (having static and dynamic data structures) results show that PAMS consumes 20% less hardware resources, 32% less on chip power and achieves a maximum speedup of 52× and 2.9× for static and dynamic data structures respectively. The results show that the PAMS multi-core system transfers data structures up to 4.65× faster than the MicroBlaze baseline system.

The design and fabrication of a generic travelling wave dielectrophoretic separation system is presented. A range of technical issues have been addressed and resolved. These include the optimization of the electrical insulation and electrical contact between different electrode layers and the choice of materials. A new method for fabricating microfluidic liquid channels, the fluidic channel cover and the seal within the channel, as well as an effective sample introduction system has been developed. A complete particle handling and fractionation system has been fabricated and the functioning of the device demonstrated with latex particles.
Direct fabrication of silicon photonic devices on a flexible platform and its application for strain sensing (2012)

We demonstrate a process to fabricate silicon photonic devices directly on a plastic film which is both flexible and transparent. This process allows the integration of complex structures on plastic films without the need of transferring from another substrate. Waveguides, grating couplers, and microring resonators are fabricated and optically characterized. An optical strain sensor is shown as an application using 5 µm-radius microring resonators on the flexible substrate. When strain is applied, resonance wavelength shifts of the microring resonators are observed. Contributions of different effects are analyzed and evaluated. Finally, we measure the influence of residual strain and confirm the material undergoes elastic deformation within the applied strain range.
Didox, a ribonucleotide reductase inhibitor, induces apoptosis and inhibits DNA repair in multiple myeloma cells (2006)

Ribonucleotide reductase (RR) is the enzyme that catalyses the rate-limiting step in DNA synthesis, the production of deoxynucleotides. RR activity is markedly elevated in tumour tissue and is crucial for cell division. It is therefore an excellent target for cancer chemotherapy. This study examined the anti-myeloma activity of Didox (3,4-Dihydroxybenzohydroxamic acid), a novel RR inhibitor (RRI). Our data showed that Didox induced caspase-dependent multiple myeloma (MM) cell apoptosis. Didox, unlike other RRIs that mainly target the pyrimidine metabolism pathway, targets both purine and pyrimidine metabolism pathways in MM, as demonstrated by transcriptional profiling using the Affymetrix U133A 2.0 gene chip. Specifically, a >or=2-fold downregulation of genes in these anabolic pathways was shown as early as 12 h after exposure to Didox. Furthermore, apoptosis was accompanied by downregulation of bcl family proteins including bcl-2, bcl(xl), and XIAP. Importantly, RR M1 component transcript was also downregulated, associated with decreased protein expression. Genes involved in DNA repair mechanisms, specifically RAD 51 homologue, were also downregulated. As Didox acts on MM cells by inhibiting DNA synthesis and repair, combination studies with melphalan, an agent commonly used in MM, were performed. A strong in vitro synergism was shown, with combination indices of <0.7 as determined by the Chou-Talalay method. These studies therefore provide the preclinical rationale for evaluation of Didox, alone and in combination with DNA-damaging agents, to improve patient outcome in MM.
Abstract 17066: Cellular Repressor of E1A-Stimulated Genes Protects From Myocardial Ischemia/Reperfusion Injury by Regulating Myocardial Autophagy and Apoptosis (2015)

Background: Cellular repressor of E1A-stimulated genes (Creg) is a secreted glycoprotein that regulates tissue and cell homeostasis and has been shown to antagonize heart injury; however, little is known about the role of CREG in ischemia/reperfusion injury (IRI). In this study, we aimed to investigate the role of CREG in cardiac IRI and clarify the mechanism. Methods: Myocardial ischemia/reperfusion (MIR) was established by ligation of left descending coronary artery for 30 min in wild type C57 mice (Creg+/+) and heterozygous Creg mice (Creg+/–). Expression of CREG was determined by Western Blot. Infarction size was determined by TTC and Evan’s Blue staining 24 hours after MIR. Cardiac function was evaluated by echocardiography at day 28. Recombinant CREG protein (0.3mg/kg·d) was supplemented through micro-pump embedded subcutaneously in Creg+/+ mice. Cardiac function and infarction size were assessed as mentioned above. Apoptosis, lysosome formation and function were detected in both heart tissue and cardiomyocyte cell line H9C2. Results: Level of CREG protein in mouse hearts was downregulated after mice were subjected to MIR, especially in Creg+/– mice. Creg+/– mice had larger infarction sizes after 24 hours of MIR treatment and worse cardiac function at day 28 compared with Creg+/+ mice. However, cardiac function was significantly improved in Creg+/+ mice treated with recombinant CREG protein. In Creg+/– mice, the number of cardiomyocytes undergoing apoptosis was increased, and LC3A and p62 accumulated, suggesting that autophagy was dysfunctional. Upregulation of CREG decreased apoptosis and activated autophagy of cardiomyocytes. Furthermore, we demonstrated that CREG protects cardiomyocytes against apoptosis by activating autophagy both in vivo and in vitro. Conclusions: CREG overexpression protects cardiac function against IRI by preventing cardiomyocyte apoptosis. The protective effects of CREG are partly mediated by activation of lysosomal autophagy.
Progress in satellite quantum key distribution (2017)

Abstract Quantum key distribution (QKD) is a family of protocols for growing a private encryption key between two parties. Despite much progress, all ground-based QKD approaches have a distance limit due to atmospheric losses or in-fibre attenuation. These limitations make purely ground-based systems impractical for a global distribution network. However, the range of communication may be extended by employing satellites equipped with high-quality optical links. This manuscript summarizes research and development which is beginning to enable QKD with satellites. It includes a discussion of protocols, infrastructure, and the technical challenges involved with implementing such systems, as well as a top level summary of on-going satellite QKD initiatives around the world.
