News Kaleidoscope: Visual Investigation of Coverage Diversity in News Event Reporting (2022)

When a newsworthy event occurs, media articles that report on the event can vary widely-a concept known as coverage diversity. To help investigate coverage diversity in event reporting, we de-velop a visual analytics system called News Kaleidoscope. News Kaleidoscope combines several backend language processing techniques with a coordinated visualization interface. Notably, News Kaleidoscope is tailored for visualization non-experts, and adopts an analytic workflow based around subselection analysis, whereby second-level features of articles are extracted to provide a more detailed and nuanced analysis of coverage diversity. To robustly evaluate News Kaleidoscope, we conduct a trio of user studies. (1) A study with news experts assesses the insights promoted for our targeted journalism-savvy users. (2) A follow-up study with news novices assesses the overall system and the specific insights pro-moted for journalism-agnostic users. (3) Based on identified system limitations in these two studies, we refine News Kaleidoscope's design and conduct a third study to validate these improvements. Results indicate that, for both news novice and experts, News Kalei-doscope supports an effective, task-driven workflow for analyzing the diversity of news coverage about events, though journalism expertise has a significant influence on the user's insights and take-aways. Our insights developing and evaluating News Kaleidoscope can aid future tools that combine visualization with natural language processing to analyze coverage diversity in news event reporting.
TCP/IP Stack Implementation for Communication over IP with AUTOSAR Ethernet Specification (2013)

The new generation vehicle will provide connectivity and telematics services for enabling vehicle communication. The communication over IP in TCP/IP means enables a connection between external node and in- vehicle nodes using IP protocols. In order to bring IP into the vehicle communication Ethernet technology is needed. Ethernet technology will provide high speed data transmission. A hardware independent Ethernet driver is necessary for providing Ethernet services. In vehicle diagnostics, the diagnostic tools and vehicles are separated by an internetwork. The main aim of using IP into the family of automotive communication protocol is that the development of new in-vehicle network has led to the need for communication between external equipment and onboard Electronic Control Units (ECUs) using many data link layer technologies. Diagnostic Over IP (DoIP) is a protocol mainly used for communication between off-board and on-board diagnostic system. This will improve the opportunities of interconnecting in-vehicle networks with internet for many new applications, including online, remote automotive diagnostics. Due to the limited resource availability in embedded devices, lightweight TCP/IP implementation is adopted. AutoSAR (Automotive Open System Architecture) is a standardized architecture introduced by a group of automobile manufacturers, suppliers and tool developers for developing and integrating software modules from different vendors.
<i>COS1</i> , a two-component histidine kinase that is involved in hyphal development in the opportunistic pathogen <i>Candida albicans</i> (1998)

Two-component histidine kinases recently have been found in eukaryotic organisms including fungi, slime molds, and plants. We describe the identification of a gene, COS1, from the opportunistic pathogen Candida albicans by using a PCR-based screening strategy. The sequence of COS1 indicates that it encodes a homolog of the histidine kinase Nik-1 from the filamentous fungus Neurospora crassa. COS1 is also identical to a gene called CaNIK1 identified in C. albicans by low stringency hybridization using CaSLN1 as a probe [Nagahashi, S., Mio, T., Yamada-Okabe, T., Arisawa, M., Bussey, H. & Yamada-Okabe, H. (1998) Microbiol. 44, 425-432]. We assess the function of COS1/CaNIK1 by constructing a diploid deletion mutant. Mutants lacking both copies of COS1 appear normal when grown as yeast cells; however, they exhibit defective hyphal formation when placed on solid agar media, either in response to nutrient deprivation or serum. In constrast to the Deltanik-1 mutant, the Deltacos1/Deltacos1 mutant does not demonstrate deleterious effects when grown in media of high osmolarity; however both Deltanik-1 and Deltacos1/Deltacos1 mutants show defective hyphal formation. Thus, as predicted for Nik-1, Cos1p may be involved in some aspect of hyphal morphogenesis and may play a role in virulence properties of the organism.
Improved Cuckoo Search (ICS) algorthm for constrained optimization problems (2014)

Constrained optimization is very important issue in engineering design. The problem of constrained optimization contains the objective function with linear and nonlinear constraint equations. In this paper the Improved Cuckoo Search (ICS) algorithm has been applied for solving problems of constrained engineering optimization, which gives better solutions than the standard CS algorithm and the other optimization algorithms used in solving engineering problems from the literature. In the proposed ICS algorithm, dynamic change of parameters of probability and step size is introduced, which are constant in the standard algorithm.

Streptomycin‐resistant ( <i>rpsL</i> ) or rifampicin‐resistant ( <i>rpoB</i> ) mutation in <i>Pseudomonas putida</i> KH146‐2 confers enhanced tolerance to organic chemicals (2002)

We found that certain Str-, Gen- or Rif- mutants derived from Pseudomonas putida KH146-2, which are resistant to streptomycin, gentamicin or rifampicin, respectively, are tolerant to the aromatic compound 4-hydroxybenzoate (4HBA). The minimum inhibitory concentration (MIC) of 4HBA as the sole carbon source for the wild-type strain was 1%, whereas the MIC for the mutants was 1.7%. Frequency of 4HBA-tolerant mutants among spontaneous Str-, Gen- and Rif- mutants was 5-15%, 3-5%, and 3% respectively. These 4HBA-tolerant mutants also tolerated to a variety of organic chemicals such as 3-hydroxybenzoate, aliphatic and heterocyclic compounds, chlorobenzoates, as well as organic solvents toluene and m-xylene. The Str mutants had a point mutation in the rpsL gene, which produces the ribosomal protein S12. The Rif mutants were found to have a point mutation in the rpoB gene, which encodes the RNA polymerase beta-subunit. Mutation points in Gen mutants still remain unknown. Str-, Gen- and Rif-phenotypes occurred in spontaneous 4HBA-tolerant mutants which had been selected by successively increasing concentrations (from 0.8% to 5%) of 4HBA. Complementation experiments with one of the Str mutants demonstrated a causal relationship between a rpsL mutation (str-1) and 4HBA tolerance. Uptake experiments using [14C]-4HBA revealed that apparent ability of 4HBA to be taken up by the membrane transport system was reduced two to threefold in the mutants compared to the wild-type strain, accounting at least partly for the enhanced tolerance to 4HBA. Our approaches thus could be effective in improvement of tolerance to aromatic compounds of bacteria applicable for bioremediation.
Design of low density generator matrix codes for continuous phase modulation (2005)

We investigate the low density generator matrix (LDGM) codes for continuous phase modulation (CPM). The nonsystematic version of LDGM codes is used in the scheme. The overall system has linear encoding complexity due to the low complexity of the LDGM codes. A property of the check node degree of the LDGM code is shown. We use the EXIT chart/function to optimize the LDGM codes. The EXIT function of CPM with a fixed SNR (signal-to-noise-ratio) is shown. We derive the union bound to analyze the error floor performance. Design approaches for lowering error floors are suggested from the analysis process. Numerical results show that this scheme converges earlier (lower SNR) than best found serially concatenated CPM (SCCPM) for iterative decoding while maintaining comparable error floors.
Assessing an Epidemic (2020)

The brief and easily administered DSM-5 Level 2 Substance Use screener shows promise for improving identification of substance use in an inpatient psychiatric hospital setting. This measure may also provide psychiatric inpatient nursing staff with a means of working collaboratively with patients to assess substance use and coordinate appropriate treatment plans.
Regeneration of Hyaline Cartilage by Cell-Mediated Gene Therapy Using Transforming Growth Factor <i>β</i> 1-Producing Fibroblasts (2001)

Transforming growth factor beta (TGF-beta) has been considered as a candidate for gene therapy of orthopedic diseases. The possible application of cell-mediated TGF-beta gene therapy as a new treatment regimen for degenerative arthritis was investigated. In this study, fibroblasts expressing active TGF-beta 1 were injected into the knee joints of rabbits with artificially made cartilage defects to evaluate the feasibility of this therapy for orthopedic diseases. Two to 3 weeks after the injection there was evidence of cartilage regeneration, and at 4 to 6 weeks the cartilage defect was completely filled with newly grown hyaline cartilage. Histological analyses of the regenerated cartilage suggested that it was well integrated with the adjacent normal cartilage at the sides of the defect and that the newly formed tissue was indeed hyaline cartilage. Our findings suggest that cell-mediated TGF-beta 1 gene therapy may be a novel treatment for orthopedic diseases in which hyaline cartilage damage has occurred.
Childhood functional gastrointestinal disorders (1999)

This is the first attempt at defining criteria for functional gastrointestinal disorders (FGIDs) in infancy, childhood, and adolescence. The decision-making process was as for adults and consisted of arriving at consensus, based on clinical experience. This paper is intended to be a quick reference. The classification system selected differs from the one used in the adult population in that it is organized according to main complaints instead of being organ-targeted. Because the child is still developing, some disorders such as toddler's diarrhea (or functional diarrhea) are linked to certain physiologic stages; others may result from behavioral responses to sphincter function acquisition such as fecal retention; others will only be recognizable after the child is cognitively mature enough to report the symptoms (e.g., dyspepsia). Infant regurgitation, rumination, and cyclic vomiting constitute the vomiting disorders. Abdominal pain disorders are classified as: functional dyspepsia, irritable bowel syndrome (IBS), functional abdominal pain, abdominal migraine, and aerophagia. Disorders of defecation include: infant dyschezia, functional constipation, functional fecal retention, and functional non-retentive fecal soiling. Some disorders, such as IBS and dyspepsia and functional abdominal pain, are exact replications of the adult criteria because there are enough data to confirm that they represent specific and similar disorders in pediatrics. Other disorders not included in the pediatric classification, such as functional biliary disorders, do occur in children; however, existing data are insufficient to warrant including them at the present time. For these disorders, it is suggested that, for the time being, clinicians refer to the criteria established for the adult population.
Current Use of Clozapine in Parkinson Disease and Related Disorders (2010)

Clozapine may be useful in the management of movement disorders and related symptoms so long as adequate supervision and monitoring can be provided.
Broadband microstrip patch antenna with reduced transversal size (2010)

In the paper we present the proposal of broadband patch antenna with reduced transversal size. The broadband operation is obtained by means of application of thick substrate and electromagnetic coupling made of two slots. The nonresonant dimension of the antenna is reduced by using H-type slot instead of simple rectangular slot. The antenna has been designed and fabricated and 29% bandwidth for WFS<1.5 has been achieved. The broadband matching has been confirmed by the measurement of the reflection coefficient of fabricated antenna. However, the radiation pattern in E-plane shows some irregularities and needs additional research.
Storing and Indexing RDF Data in a Column-Oriented DBMS (2010)

Effcient RDF data management is an essential factor in realizing the Semantic Web vision. However, most existing RDF storage schemes based on row-store relational databases are constrained in terms of efficiency and scalability. In this paper, we propose an RDF storage scheme that implements sextuple indexing for RDF triples using a column-oriented DBMS. To evaluate the performance of our approach, large-scale datasets upto 13 million triples are generated and benchmark queries that cover important RDF join patterns are devised. The experimental results show that our approach outperforms the row-oriented DBMS approach by upto an order of magnitude and is even competitive to the best state-of-the-art native RDF store.
Analysis of striping techniques in robotic storage libraries (2002)

In recent years advances in computational speed have been the main focus of research and development in high performance computing. In comparison, the improvement in I/O performance has been modest. Faster processing speeds have created a need for faster I/O as well as for the storage and retrieval of vast amounts of data. The technology needed to develop these mass storage systems exists today. Robotic storage libraries are vital components of such systems. However, they normally exhibit high latency and long transmission times. We analyze the performance of robotic storage libraries and study striping as a technique for improving response time. Although striping has been extensively studied in the content of disk arrays, the architectural differences between robotic storage libraries and arrays of disks suggest that a separate study of striping techniques in such libraries would be beneficial.
Heterogeneous Isolated Execution for Commodity GPUs (2019)

Traditional CPUs and cloud systems based on them have embraced the hardware-based trusted execution environments to securely isolate computation from malicious OS or hardware attacks. However, GPUs and their cloud deployments have yet to include such support for hardware-based trusted computing. As large amounts of sensitive data are offloaded to GPU acceleration in cloud environments, ensuring the security of the data is a current and pressing need. As deployed today, the outsourced GPU model is vulnerable to attacks from compromised privileged software. To support isolated remote execution on GPUs even under vulnerable operating systems, this paper proposes a novel hardware and software architecture, called HIX (Heterogeneous Isolated eXecution). HIX does not require modifications to the GPU architecture to offer protections: Instead, it offers security by modifying the I/O interconnect between the CPU and GPU, and by refactoring the GPU device driver to work from within the CPU trusted environment. A result of the architectural choices behind HIX is that the concept can be applied to other offload accelerators besides GPUs. This work implements the proposed HIX architecture on an emulated machine with KVM and QEMU. Experimental results from the emulated security support with a real GPU show that the performance overhead for security is curtailed to 26% on average for the Rodinia benchmark, while providing secure isolated GPU computing.
Training Skinny Deep Neural Networks with Iterative Hard Thresholding Methods (2016)

Deep neural networks have achieved remarkable success in a wide range of practical problems. However, due to the inherent large parameter space, deep models are notoriously prone to overfitting and difficult to be deployed in portable devices with limited memory. In this paper, we propose an iterative hard thresholding (IHT) approach to train Skinny Deep Neural Networks (SDNNs). An SDNN has much fewer parameters yet can achieve competitive or even better performance than its full CNN counterpart. More concretely, the IHT approach trains an SDNN through following two alternative phases: (I) perform hard thresholding to drop connections with small activations and fine-tune the other significant filters; (II)~re-activate the frozen connections and train the entire network to improve its overall discriminative capability. We verify the superiority of SDNNs in terms of efficiency and classification performance on four benchmark object recognition datasets, including CIFAR-10, CIFAR-100, MNIST and ImageNet. Experimental results clearly demonstrate that IHT can be applied for training SDNN based on various CNN architectures such as NIN and AlexNet.
Substrate constraint modifies the Rayleigh spectrum of vibrating sessile drops (2013)

In this work, we study the resonance behavior of mechanically oscillated, sessile water drops. By mechanically oscillating sessile drops vertically and within prescribed ranges of frequencies and amplitudes, a rich collection of resonance modes are observed and their dynamics subsequently investigated. We first present our method of identifying each mode uniquely, through association with spherical harmonics and according to their geometric patterns. Next, we compare our measured resonance frequencies of drops to theoretical predictions using both the classical theory of Lord Rayleigh and Lamb for free, oscillating drops, and a prediction by Bostwick and Steen that explicitly considers the effect of the solid substrate on drop dynamics. Finally, we report observations and analysis of drop mode mixing, or the simultaneous coexistence of multiple mode shapes within the resonating sessile drop driven by one sinusoidal signal of a single frequency. The dynamic response of a deformable liquid drop constrained by the substrate it is in contact with is of interest in a number of applications, such as drop atomization and ink jet printing, switchable electronically controlled capillary adhesion, optical microlens devices, as well as digital microfluidic applications where control of droplet motion is induced by means of a harmonically driven substrate.
Kinetics of the Innate Immune Response After Trauma (2013)

Phenotyping blood PMNs enables identification of the kinetics and magnitude of the initial systemic inflammatory response after injury. The decreased functionality of PMNs and monocytes reaches its minimum before the development of sepsis and could be an important contributing factor. This could support the early identification of patients at risk.
Service and connection management architecture for distributed multimedia applications (2002)

This paper addresses a novel networking architecture model on DPE for various multimedia services suitable to high speed networks and for the flexible and rapid introduction of services. In this model, applications are assembled from software "building blocks" which cope with information service and network providers. Each building block provides a layered view, enabling the effective management of multimedia network resources and services according to the concept of TMN and TINA. In this paper, we also propose the use of a directory system and its naming structure for the management of user profiles and session profiles, and a control model of effective multimedia logical device objects that uses a stream process approach. Our model is implemented on a DPE platform that provides various transparencies. For the purpose of flexible service provision to users, this architecture presents ad hoc service building blocks such as a video on demand building block and a CSCW building block.
Photochemistry of hydrated electron clusters (H2O)−<i>n</i> (15≤<i>n</i>≤40) at 1064 nm: Size dependent competition between photofragmentation and photodetachment (1988)

Photofragmentation is found to be surprisingly efficient when hydrated electron clusters (H2O)−n, 15≤n≤40, are excited at 1064 nm (1.165 eV). The decay probability into ionic channels rises sharply from zero in the size range 15≤n≤20 before leveling off at a value of 0.56±0.10. The propensity of smaller clusters to detach an electron rather than fragment is correlated with the peculiar shape of the cluster ion distribution obtained by dissociative attachment of low energy electrons onto neutral water clusters, where the ionic clusters are only observed in abundance for n≥11.
1.72-Tb/s Virtual-Carrier-Assisted Direct-Detection Transmission Over 200 km (2017)

Supporting the ever-increasing data-center-inter-connect traffic in a cost-effective manner is a great challenge, which requires innovative transmission and digital signal processing (DSP) techniques. Recently, single-side-band (SSB) direct-detection (DD) transmissions have been actively considered for data rates beyond 100 Gb/s per channel and distance of hundreds of kilometers due to its capability of electronic chromatic dispersion compensation. In addition, several effective DSP techniques to mitigate or suppress the signal-signal beating interference (SSBI) due to the squared-law detection of the photodiode have been intensively investigated, such as Kramers-Knonig (KK) and SSBI cancellation schemes, showing promising performance at data rates over 200 Gb/s and distance beyond 100 km. In this paper, we demonstrate that high-performance low-complexity SSB DD transmissions can be achieved by generating a digital carrier (virtual carrier) together with the complex information-bearing signal at the transmitter using only two digital-to-analog converters. Combining this transmission technique with either the KK field reconstruction or a two-stage SSBI cancellation scheme at the receiver, eight-channel WDM signals with a net data rate of 1.72 Tb/s have been transmitted successfully over a record span length of 200 km at 1550 nm.
