Towards Context-Aware Opinion Summarization for Monitoring Social Impact of News (2020)

Opinion mining and summarization of the increasing user-generated content on different digital platforms (e.g., news platforms) are playing significant roles in the success of government programs and initiatives in digital governance, from extracting and analyzing citizen’s sentiments for decision-making. Opinion mining provides the sentiment from contents, whereas summarization aims to condense the most relevant information. However, most of the reported opinion summarization methods are conceived to obtain generic summaries, and the context that originates the opinions (e.g., the news) has not usually been considered. In this paper, we present a context-aware opinion summarization model for monitoring the generated opinions from news. In this approach, the topic modeling and the news content are combined to determine the “importance” of opinionated sentences. The effectiveness of different developed settings of our model was evaluated through several experiments carried out over Spanish news and opinions collected from a real news platform. The obtained results show that our model can generate opinion summaries focused on essential aspects of the news, as well as cover the main topics in the opinionated texts well. The integration of term clustering, word embeddings, and the similarity-based sentence-to-news scoring turned out the more promising and effective setting of our model.

Judicial activism has a wide variety of definitions, while its true content remains unclear.
Forward-looking automotive radar using a W-band single-chip transceiver (1995)

A prototype W-band all-weather automotive radar based on a single-chip 0.1-/spl mu/m AlGaAs-InGaAs-GaAs HEMT transceiver has been developed. This radar has the features of simple architecture and small size, with adequate performance. Owing to the maturity of HEMT MMIC technology, this radar is potentially low cost to implement in personal vehicles. The prototype radar used for autonomous intelligent cruise control in a passenger car is presented in this paper. The MMIC development, together with the radar system design, is also addressed. >
ProofRite: A Paper-Augmented Word Processor (2004)

Proofreading digital documents on paper is a common pattern of use among word processor users [7]. Yet, at present, there are no word processing programs that let users merge information gathered on a printout back into the digital version of the document. In this paper we present ProofRite, an extended version of the AbiWord word processor [1], which lets users merge annotations and markings made on a printout with the original digital version of a document. Upon merging, marks are anchored in the document such that they can reflow with the text they are attached to. ProofRite showcases the first full implementation of the Paper Augmented Digital Document system [4] and shows how cohabitation between the digital and the paper world might simplify user workflow in many office-related tasks.
A three-parameter equation for molecular weight distribution of low-density polyethylene (1972)

A new three-parameter distribution function is proposed which fits best the experimental molecular weight distribution curves of branched lowdensity polyethylenes. The data were interpreted from GPC measurements, and a special computer program was utilized in order to derive the best values of the empirical constants a, b, and c.
Design and Optimization of Microchannel Cooling Systems (2006)

Microchannel heat sinks have been shown to exhibit significant heat transfer rates from extremely small volumes, albeit at the expense of moderately high pumping power. However, their successful integration into commercially viable miniature cooling systems will likely be determined by system-level factors such as energy efficiency, weight, volume, manufacturability, material compatibility, and ultimately, cost. While previous studies have focused on optimizing the microchannel heat sink device in isolation, the present study focuses on the entire system comprising a microchannel heat sink, a pump, a liquid-to-air plate and fin compact heat exchanger, and a fan or blower. A thermal resistance-based network model is constructed to characterize the system physics. Heat transfer and flow parameters for the liquid and air sides, as well as spreading in the microchannel heat sink base, are predicted using correlations from the literature. Heat extraction optimization is linked to heat rejection capability to allow for a holistic approach. Optimal system design with and without manufacturability constraints is presented to quantify the "gap" between ideal and practical solutions. Analysis is carried out for copper microchannel heat sink and heat exchanger materials, with water as the liquid side coolant, and with a commercial pump and fan as fluid moving devices
Evaluating virtual reality and augmented reality training for industrial maintenance and assembly tasks (2013)

The current study evaluated the use of virtual reality (VR) and augmented reality (AR) platforms, developed within the scope of the SKILLS Integrated Project, for industrial maintenance and assembly (IMA) tasks training. VR and AR systems are now widely regarded as promising training platforms for complex and highly demanding IMA tasks. However, there is a need to empirically evaluate their efficiency and effectiveness compared to traditional training methods. Forty expert technicians were randomly assigned to four training groups in an electronic actuator assembly task: VR (training with the VR platform twice), Control-VR (watching a filmed demonstration twice), AR (training with the AR platform once), and Control-AR (training with the real actuator and the aid of a filmed demonstration once). A post-training test evaluated performance in the real task. Results demonstrate that, in general, the VR and AR training groups required longer training time compared to the Control-VR and Control-AR groups, respectively. There were fewer unsolved errors in the AR group compared to the Control-AR group, and no significant differences in final performance between the VR and Control-VR groups, probably due to a ceiling effect created by the use of two training trials in the selected task for participants who were expert technicians. The results suggest that use of the AR platform for training IMA tasks should be encouraged and use of the VR platform for that purpose should be further evaluated.
Bond order and valence indices: A personal account (2006)

The paper accounts for the author's activity in developing bond order and valence indices since the early 80s. These indices represent an important conceptual link between the physical description of molecules as systems of electrons and nuclei and the chemical picture of molecules consisting of atoms kept together by bonds. They are also useful for a systematization and interpretation of the results obtained in the quantum chemical calculations, by permitting to extract from the wave function different pieces of information that may be assigned chemical significance. In some cases they can have some predictive power, too. Historically, the prototypes of such indices were introduced in the semiempirical quantum chemistry; the most important developments were Coulson's charge-bond order matrix in the simple Hückel theory and the Wiberg index in the CNDO framework. (Valence indices were also introduced in the semiempirical theory.) The definition of the ab initio bond order index emerged from the asymptotic term of the exchange energy component of the partitioning performed in the framework of the author's so-called "chemical Hamiltonian approach" using a "mixed" second quantization formalism for overlapping basis sets. They can also be introduced by studying the exchange part of the two-particle density (or of the second-order density matrix). Some properties of the bond order indices are discussed and the author's (until now unpublished) proof is also presented, showing the sufficient conditions under which the bond order index of a homonuclear diatomics is equal to the "chemist's bond order," i.e., the half of the difference between the number of electrons occupying bonding and antibonding orbitals. The ab initio valence indices are also introduced and discussed, and it is stressed that for correlated wave function the same "exchange only" definition of the bond order and valence indices should be used, which was introduced for the SCF case. The recent concept of the "atomic decomposition of identity" is also discussed and it is utilized for introducing bond orders and valences in the framework of the "3D analysis," when atoms are defined not by their basis orbitals but as regions of the three-dimensional (3D) physical space. Two versions of the 3D analysis are considered--the AIM (atoms in molecules)-type decomposing the space into disjunct atomic domains and the "fuzzy atoms" scheme in which there are no sharp boundaries between the atoms but they exhibit a continuous transition from one to another.
Molecular recognition between ligands and nucleic acids: novel pyridine- and benzoxazole-containing agents related to Hoechst 33258 that exhibit altered DNA sequence specificity deduced from footprinting analysis and spectroscopic studies (1990)

The syntheses of certain analogues of the DNA minor groove binding agent Hoechst 33258 designed to exhibit altered sequence recognition are described. The structural modifications include the following: substitution of pyridine for the benzene ring of the benzimidazole moiety, replacement of one benzimidazole unit by a benzoxazole in the two possible orientations with respect to the DNA receptor, and a synthesis of 2,2'-m-phenylene-bis[6-(4-methyl-1-piperazinyl)benzimidazole]. Sequence recognition of these agents on a HindIII/EcoRI fragment of pBR322 DNA was determined by MPE footprinting procedures. Some of the analogues exhibited altered DNA sequence preference compared with Hoechst 33258. In particular, a structure bearing a benzoxazole moiety with the oxygen oriented inward to the minor groove together with an inward-directed pyridine nitrogen appears to confer the property of recognition of a GC base pair within the binding sequence. The possible factors, structural, stereochemical, and electrostatic, contributing to the altered DNA sequence recognition properties are discussed.
Simulated and measured results from a Duroid-based planar MBG cavity resonator filter (2000)

A planar Microwave Band Gap (MBG) cavity resonator filter that is completely compatible with current commercial printed circuit board (PCB) fabrication techniques has been designed, fabricated and tested. This filter provides a 1.33% bandwidth passband response at 10.67 GHz with a corresponding insertion loss of 2.17 dB. Design considerations and equations are presented which demonstrate that the resonant frequency and Q of the resonator can be adjusted as desired.
hMSH2 forms specific mispair-binding complexes with hMSH3 and hMSH6 (1996)

The genetic and biochemical properties of three human MutS homologues, hMSH2, hMSH3, and hMSH6, have been examined. The full-length hMSH6 cDNA and genomic locus were isolated and characterized, and it was demonstrated that the hMSH6 gene consisted of 10 exons and mapped to chromosome 2p15-16. The hMSH3 cDNA was in some cases found to contain a 27-bp deletion resulting in a loss of nine amino acids, depending on the individual from which the cDNA was isolated. hMSH2, hMSH3, and hMSH6 all showed similar tissue-specific expression patterns. hMSH2 protein formed a complex with both hMSH3 and hMSH6 proteins, similar to protein complexes demonstrated by studies of the Saccharomyces cerevisiae MSH2, MSH3, and MSH6. hMSH2 was also found to form a homomultimer complex, but neither hMSH3 nor hMSH6 appear to interact with themselves or each other. Analysis of the mismatched nucleotide-binding specificity of the hMSH2-hMSH3 and hMSH2-hMSH6 protein complexes showed that they have overlapping but not identical binding specificity. These results help to explain the distribution of mutations in different mismatch-repair genes seen in hereditary nonpolyposis colon cancer.

Current status and future potential of somatic mutation testing from circulating free DNA in patients with solid tumours (2010)

Genetic alterations can determine the natural history of cancer and its treatment response. With further advances in DNA sequencing technology, multiple novel genetic alterations will be discovered which could be exploited as prognostic, predictive and pharmacodynamic biomarkers in the development and use of cancer therapeutics. As such, the importance in clinical practice of efficient and robust somatic mutation testing in solid tumours cannot be overemphasized in the current era of personalized medicine. However, significant challenges remain regarding the testing of genetic biomarkers in clinical practice. Reliance on archived formalin fixed, paraffin embedded tumour, obtained from diagnostic biopsies, for testing somatic genetic alterations could restrict the scientific community in asking relevant questions about a patient's cancer biology. Problems inherent with using formalin fixed, archival tissue are well recognized and difficult to resolve. It could be argued that to achieve rapid and efficient incorporation of genetic biomarkers into clinical practice, somatic mutation testing in cancer patients should be simpler, less invasive using a readily available clinical sample, whilst maintaining robustness and reproducibility. In this regard, use of circulating free DNA (cfDNA) from plasma or serum as an alternative and/or additional source of DNA to test cancer specific genetic alterations is an attractive proposition. In light of encouraging results from recent studies, this mini review will discuss the current role and future potential of somatic mutation testing from circulating or cell free DNA derived from the blood of patients with solid tumours.
FPGA based digital high frequency beamformers for arrays (2005)

We have developed two digital beamformers for eye imaging using 30-50 MHz transducer arrays: a 6-channel digital beamformer for a six-ring annular array ultrasound transducer (43 MHz) and a 16-channel digital beamformer for a linear array ultrasound transducer (30 MHz) of 48-64 elements. The hardware allows the flexibility for multiple transmit focusing, dynamic receive focusing, amplitude apodization, and dynamic aperture control. Individual channel delays are applied using a combination of coarse and fine delays. The coarse delays are integer multiples of the clock periods achieved by using a FIFO structure, and the fine delays are applied with interpolation of a 4-tap fractional delay (FD) FIR filter. The dynamic receive focusing is implemented based on a state machine which updates delay values and the FD filter coefficients according to the depth of the echoes. The aperture apodization is set according to the focusing zone. Cross-sectional wire target images, using a 20 /spl mu/m diameter wire, from both arrays are shown. The images of an excised pig eye clearly show the fine structures of the anterior segment, including cornea and lens.
Optical and Electrical Properties of Epitaxial and Diffused GaAs Injection Lasers (1967)

GaAs injection lasers were prepared by an epitaxial solution growth method and their properties compared with those of diffused junctions. The optical gain factor β was up to a factor of 7 higher for the epitaxial diodes at 300°K. This resulted in threshold current densities as low as 26 000 A/cm2 (3.8×10−3 cm length) at 300°K. At 77°K, gain factor and loss numbers were similar for the two laser types. The spontaneous line-width of the epitaxial lasers was unusually large (∼300 Å at 77°K) and increased with decreasing junction voltage. The internal quantum efficiency of epitaxial diodes drops from 100% at 4.2°K to 40% at 300°K. The vertical beam spread was found to be between 20°–30° half-width at 77°K as well as at 300°K. Diffused diodes frequently show a delay between the current pulse and the stimulated emission of up to 30 nsec, dependent on the current value at higher temperatures. No such delay was observed in epitaxial lasers.
Oxidative Dehydrogenation of Hydrocarbons (1977)

Experimental data are examined and the present state of the theory of the oxidative dehydrogenation reactions of hydrocarbons is discussed. Fundamental varieties of oxidative dehydrogenation have been considered as a function of dehydrogenating agent and the involvement of the solid surface in the process. Attention is concentrated on the elucidation of the process characteristics, the reaction mechanisms, and the nature of the active surface. The bibliography includes 196 references.

Glycoproteomic Analysis by Two-Dimensional Electrophoresis (2009)

Changes in N-linked glycosylation are known to occur during the development of cancer. For example, increased branching of oligosaccharides has been associated with metastasis and has been correlated to tumor progression in human cancers of the breast, colon, and melanomas. Increases in core fucosylation have also been associated with the development of hepatocellular carcinoma (HCC). To a large extent, the proteins to which these N-linked glycans are attached have been unknown. However, with the advent of sensitive glycan analysis and proteomic technologies, the ability to comprehensively identify all the fucosylated proteins in a given population is now a possibility. This method, generally referred to as targeted glycoproteomics, is shown as applied to the detection of proteins present in the fucosylated proteome of a liver cancer cell line but is generally enough to be applied in many other situations.
A Probabilistic Approach to Optical Flow based Super-Resolution (2005)

This paper deals with the computation of a single super-resolution image from a set of low-resolution images, where the motion fields are not constrained to be parametric. In our approach, the inversion process, in which the super-resolved image is inferred from the input data, is interleaved with the computation of a set of dense optical flow fields. The case of arbitrary motion presents several significant challenges. First of all, the super-resolution setting dictates that the optic flow computations must be very precise. Furthermore, we have to consider the possibility that certain parts of the scene, which are visible in the super-resolved image, are occluded in some of the input images. Such occlusions must be identified and dealt with in the restoration process. We propose a Bayesian approach to tackle these problems. In this framework, the input images are regarded as sub-sampled and noisy versions of the unknown high-quality image. Also, the input data is considered incomplete, in the sense that we do not know which pixels from the evolving super-resolution image are occluded in particular images from the input set. This will be modeled by introducing so-called visibility maps, which are treated as hidden variables. We describe an EM-algorithm, which iterates between estimating values for the hidden quantities, and optimizing the flow-fields and the super-resolution image. The approach is illustrated with a synthetic and a challenging real-world example.

Sensorimotor Gating and Thought Disturbance Measured in Close Temporal Proximity in Schizophrenic Patients (1999)

Assessment of information processing and thought disturbance measures in close temporal proximity resulted in strong evidence that gating deficits correlate highly with measures of perceptual and reasoning disturbances. This relationship may form an important basis for the cognitive dysfunction observed among schizophrenic patients.
Implementation of WirelessHART in the NS-2 Simulator and Validation of Its Correctness (2014)

One of the first standards in the wireless sensor networks domain,WirelessHART (HART (Highway Addressable Remote Transducer)), was introduced to address industrial process automation and control requirements. This standard can be used as a reference point to evaluate other wireless protocols in the domain of industrial monitoring and control. This makes it worthwhile to set up a reliable WirelessHART simulator in order to achieve that reference point in a relatively easy manner. Moreover, it offers an alternative to expensive testbeds for testing and evaluating the performance of WirelessHART. This paper explains our implementation of WirelessHART in the NS-2 network simulator. According to our knowledge, this is the first implementation that supports the WirelessHART network manager, as well as the whole stack (all OSI (Open Systems Interconnection model) layers) of the WirelessHART standard. It also explains our effort to validate the correctness of our implementation, namely through the validation of the implementation of the WirelessHART stack protocol and of the network manager. We use sniffed traffic from a real WirelessHART testbed installed in the Idrolab plant for these validations. This confirms the validity of our simulator. Empirical analysis shows that the simulated results are nearly comparable to the results obtained from real networks. We also demonstrate the versatility and usability of our implementation by providing some further evaluation results in diverse scenarios. For example, we evaluate the performance of the WirelessHART network by applying incremental interference in a multi-hop network.
Stimulated Emission and Laser Action in Gallium Nitride (1971)

Stimulated emission and laser action have been observed near 3.45 eV in single-crystal needles of GaN. These observations support the earlier suggestion that GaN is a direct band-gap semiconductor with Eg∼3.50 eV at 2°K. Furthermore, the occurrence of very high gain (g∼105 cm−1) in the stimulated emission emphasizes the possible device potential of this material.
