How to Test in Sixteen Languages? Automation Support for Localization Testing (2017)

Developing for a global market requires the internationalization of software products and their localization to different countries, regions, and cultures. Localization testing verifies that the localized software variants work, look and feel as expected. Localization testing is a perfect candidate for automation. It has a high potential to reduce the manual effort in testing of multiple language variants and to speed-up release cycles. However, localization testing is rarely investigated in scientific work. There are only a few reports on automation approaches for localization testing providing very little empirical results or practical advice. In this paper we describe the approach we applied for automated testing of the different localized variants of a large industrial software system, we report on the various bugs found, and we discuss our experiences and lessons learned.
Application of Phasor Measurement Unit on Locating Disturbance Source for Low-Frequency Oscillation (2010)

A smart power grid is an integration of the advanced measurement, communication, computer, and control techniques. Among all the state-of-the-art technologies in building a smart power grid, the phasor measurement unit (PMU) is an important and promising one. Nowadays in China, most ultrahigh- and high-voltage buses are all equipped with PMUs. This paper reports an application of PMU data on locating the disturbance source for the low-frequency oscillation that has happened several times in the interconnected big power grids in China recently. The posterior analysis by the Electric Power System Research Institute of China (CEPRI) has confirmed that these low-frequency oscillations are caused by the resonance phenomena. It is urgent to find the disturbance source in case it happens again. However, there have been no systematic and effective methods to locate the disturbance in a very large power system. The trial and error method has been implemented via the digital simulations, but in vain. To overcome this problem, a novel method is developed in this paper to locate the disturbance source with the help of PMUs. The method takes advantage of the PMU measurements to reduce the searching area for locating the disturbance source. Case studies show the efficiency of the proposed method.
Electroviscous Fluids. II. Electrical Properties (1967)

The induced interfacial polarization mechanism invoked to explain electroviscosity requires a direct relationship between the rheological and electrical properties of an electroviscous system. Static and dynamic measurements of the electric and dielectric properties of electroviscous silica dispersions were made to study these relationships. An electrokinetic potential and conductivity and a small dc power output that depend upon shear rate were observed. Electroviscous fluids under shear exhibit the characteristics of small electric cells. Shear-induced desorption of weakly held charge carriers out of the double layer is suggested to explain these effects. On application of an external electric field, electroviscosity appears at the onset of current flow. Dielectric measurements under zero-shear conditions show that the medium in contact with the disperse phase is essentially a low-dielectric-constant vehicle while the particles are composites having higher dielectric constants, thereby facilitating interfacial polarization. Anomalous dispersion occurs under zero-shear conditions at low frequencies as expected on the basis of the proposed interfacial polarization mechanism. Simultaneous dielectric-constant, loss, and electroviscosity measurements under shear conditions correlate with the effects of changing shear rate, field strength, temperature, and frequency. Increasing temperatures promote polarization while shear stresses transverse to the direction of the applied field perturb the field-induced polarization. When an electroviscous dispersion is subjected to both mechanical shearing and an external electric field, a dynamic equilibrium is established between the rheological and electrical properties of the system.

A Novel Technique Enabling the Realisation of 60 GHz Body Area Networks (2012)

This paper presents a novel technique to enable over-body propagation at 60 GHz. A flexible material has been created that enables the propagation of surface waves around the body without the need of repeaters, high powers or high gain antennas. The solution is wireless and self-redundant, and will facilitate the development of light weight, high bandwidth, and low power, wireless body area networks that could offer improvements for mobile health monitoring applications as well as utility in sports and entertainment industries.
A practical adaptive image compression technique using visual criteria for still-picture transmission with electronic mail (1990)

An efficient image compression/decompression technique for complex scenes is presented. An image is first decorrelated by a full two-dimensional DCT (discrete cosine transform). The resulting coefficient map is weighted using properties of the human visual system and finally encoded with a novel multiresolution encoder. The result is converted into printable ASCII for transmission by electronic mail.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A cross-layer parallel handover optimization scheme for WiMAX networks (2011)

The handover performance plays a crucial role in guaranteeing the quality of real-time applications in WiMAX networks. In general, a handover process can be divided into four stages: i) cell reselection, ii) handover preparation, iii) link layer handover, and iv) IP layer handover. A cross-layer parallel handover optimization (CPHO) scheme is proposed in this paper to reduce the handover signaling overhead and latency in each stage. The key idea of our proposed scheme is that uses the knowledge achieved from the backhaul inter-BS communications to reduce the HO control message load in wireless links and overlaps the executions of the link layer and the network layer handover process. Therefore the mean of the handover interruption time can be significantly reduced. The numerical analysis and simulation results show that the proposed approach significantly enhances the handover performance.
Microwave Photonic Downconversion Using Phase Modulators in a Sagnac Loop Interferometer (2013)

A new high conversion efficiency and wideband microwave photonic downconverter with infinite isolation between the RF and LO port, which enables the RF and LO to be located at different locations, is presented. It is based on two traveling wave electrooptic phase modulators inside a Sagnac loop interferometer. No dc bias voltages are required and there are no bias drift issues. High conversion efficiency downconversion is obtained by optical carrier suppression inherent from the Sagnac loop structure, which allows high-amplitude RF and LO sidebands into the photodetector. The microwave photonic downconverter topology can be extended to have multiple RF channels using a wavelength division multiplexing technique in which the phase modulators driven by the RF signals can be located in different remote locations. Experimental results are presented which demonstrate wideband operation from 5 to 20 GHz and over 26 dB conversion efficiency improvement compared to the conventional dual-series MZM-based microwave photonic downconverter.
An extended object-oriented data model for complex inter-entity relationships (2002)

Object-oriented (OO) databases are deemed to be more suitable than traditional systems (e.g. relational systems) for applications involving complex data items such as multimedia information. At present, however, OO methods have some difficulty in modelling complex relationships. In this paper, an extended OO data model is proposed in order to overcome these shortcomings. The extensions enhance the modelling capability of current OO models.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Interoperable secure voice communications in tactical systems (2000)

With the increased dependence on peace-keeping operations under the auspices of the UN and NATO, interoperability among and between coalition member nations is imperative. An essential element is to overcome differences in voice coding algorithms from system to system and nation to nation. Our goal is to ensure interoperability between communications equipment produced by different nations designed to common standards. Tactical environments are very often characterized by harsh acoustic environments, and stressed or jammed channels. The next generation tactical communications systems are conceived with interoperability as a primary consideration. A key step is to adopt a single high performance voice coding algorithmic suite. This suite must be capable of multiple transmission rates which can dynamically adapt to available bandwidth, channel SNR, or by user direction. Integrating powerful forward error correction codes will optimize the system quality of service, delivered to the user by selecting the optimal combined voice and channel coding for a given impaired scenario. Most importantly, this adaptation must occur seamlessly, dynamically and instantaneously. This paper discusses one voice coding technology, the enhanced mixed excitation linear prediction, MELPe voice coding algorithmic suite, where it is today, and the additions under development and in consideration.

Head and Cuticular Structures of Some Species in the Family Steinernematidae (Nematoda) (1981)

Head and cuticular structures of the Steinernematidae: Steinernema kraussei, Neoaplectana glaseri, N. carpocapsae and N. bibionis were compared by scanning electron microscopy. In both genera and all species studied one ring of six labial papillae and one of four cephalic papillae were clearly visible, which shows that Steinernema and Neoaplectana cannot be separated on the number of head papillae alone. Details of the morphology of the lips, openings of secretory organs and of the surface of the cuticle are given. Invasive juveniles have only one ring of four cephalic papillae.
Discovery of an oncogenic activity in p27<sup>Kip1</sup>that causes stem cell expansion and a multiple tumor phenotype (2007)

The cell cycle inhibitor p27Kip1 also has cyclin-cyclin-dependent kinase (CDK)-independent functions. To investigate the significance of these functions in vivo, we generated a knock-in mouse in which four amino acid substitutions in the cdkn1b gene product prevent its interaction with cyclins and CDKs (p27CK-). In striking contrast to complete deletion of the cdkn1b gene, which causes spontaneous tumorigenesis only in the pituitary, the p27CK- protein dominantly caused hyperplastic lesions and tumors in multiple organs, including the lung, retina, pituitary, ovary, adrenals, spleen, and lymphomas. Moreover, the high incidence of spontaneous tumors in the lung and retina was associated with amplification of stem/progenitor cell populations. Therefore, independently of its role as a CDK inhibitor, p27Kip1 promoted stem cell expansion and functioned as a dominant oncogene in vivo. Thus, the p27CK- mouse unveils a dual role for p27 during tumorigenesis: It is a tumor suppressor by virtue of its cyclin-CDK regulatory function, and also an oncogene through a cyclin-CDK-independent function. This may explain why the cdkn1b gene is rarely inactivated in human tumors, and the p27CK- mouse in which the tumor suppressor function is lost but the cyclin-CDK-independent-oncogenic-function is maintained may represent a more faithful model for the widespread role of p27 misregulation in human cancers than the p27 null.
Facile Fabrication of Core-in-Shell Particles by the Slow Removal of the Core and Its Use in the Encapsulation of Metal Nanoparticles (2008)

Core-in-shell particles with controllable core size have been fabricated from core-shell particles by means of the controlled core-dissolution method. These cores in inorganic shells were employed as scaffolds for the synthesis of metal nanoparticles. After dissolution of the cores, metal nanoparticles embedded in cores were encapsulated into the interior of shell, without any damage or change. This article describes a very simple method for deriving core-in-shell particles with controllable core size and encapsulation of nanoparticles into the interior of shell.
Effect of particle size and volume fraction on tensile properties of fly ash/polyurea composites (2010)

Fly ash, which consists of hollow particles with porous shells, was introduced into polyurea elastomer. A one-step method was chosen to fabricate pure polyurea and the polyurea matrix for the composites based on Isonate&reg; 2143L (diisocyanate) and Versalink&reg; P-1000 (diamine). Scanning electron microscopy was used to observe the fracture surfaces of the composites. Particle size and volume fraction were varied to study their effects on the tensile properties of the composites. The tensile properties of the pure polyurea and fly ash/polyurea (FA/PU) composites were tested using an Instron load frame with a 1 kN Interface model 1500ASK-200 load cell. Results showed that fly ash particles were distributed homogeneously in the polyurea matrix, and all of the composites displayed rubber-like tensile behavior similar to that of pure polyurea. The tensile strength of the composites was influenced by both the fly ash size and the volume fraction. Compared to the largest particle size or the highest volume fraction, an increase in tensile strength was achieved by reducing particle size and/or volume fraction. The strain at break of the composites also increased by using fine particles. In addition, the composites filled with 20% fly ash became softer. These samples showed lower plateau strength and larger strain at break than the other composites.
Mammalian MYC Proteins and Cancer (2014)

The MYC family of proteins is a group of basic-helix-loop-helix-leucine zipper transcription factors that feature prominently in cancer. Overexpression of MYC is observed in the vast majority of human malignancies and promotes an extraordinary set of changes that impact cell proliferation, growth, metabolism, DNA replication, cell cycle progression, cell adhesion, differentiation, and metastasis. The purpose of this review is to introduce the reader to the mammalian family of MYC proteins, highlight important functional properties that endow them with their potent oncogenic potential, describe their mechanisms of action and of deregulation in cancer cells, and discuss efforts to target the unique properties of MYC, and of MYC-driven tumors, to treat cancer.
Building distributed systems with remote procedure call (1987)

Remote procedure call is gaining popularity assimple, transparent and useful paradigm for building distributed systems. Ideal transparency means that remote procedure calls are in distinguishable from local ones. This is usually only partially achievable. This paper discusses those implementation decisions which affect transparency and intrude on the design of distributed applications built using remote procedure call.
New β-Hydroxyaspartate Derivatives Are Competitive Blockers for the Bovine Glutamate/Aspartate Transporter (1997)

Four subtypes of excitatory amino acid transporters (EAAT1-4) have been identified in the mammalian brain. A number of pharmacological agents have been developed to study their intrinsic properties and function. Up to now, blockers were available only for EAAT2, whereas all the inhibitors of glutamate uptake active on the other subtypes were proved to be substrates of the transporters. We synthesized five new derivatives of DL-threo-beta-hydroxyaspartic acid, a well known general substrate of EAATs, and investigated their potential blocking activity on the cloned bovine EAAT1 expressed in the Xenopus oocyte system, by using radiotracer and voltage-clamp techniques. Two of our derivatives proved to be substrates for bovine EAAT1, with reduced electrogenicity compared with their parent compound, and an affinity of 40 and 64 microM. The last three derivatives displayed a blocking activity on bovine EAAT1. The affinity of DL-threo-beta-benzoyloxyaspartate and DL-threo-beta-(1-naphthoyl)oxyaspartate was determined by Schild analysis as 17.2 and 52.1 microM, respectively. These blockers should help in the better understanding of the key intrinsic properties of EAAT1. Moreover, they appear as good candidates for a general blocking activity on EAATs.

The C-terminal domain of the regulatory protein NOVH is sufficient to promote interaction with fibulin 1C: A clue for a role of NOVH in cell-adhesion signaling (1999)

The NOVH protein belongs to the emerging CCN [Connective tissue growth factor (CTGF), Cyr61/Cef10, nephroblastoma overexpressed gene] family of growth regulators sharing a strikingly conserved multimodular organization but exhibiting distinctive functional features. Two members of the family (CYR61 and CTGF) are positive regulators of cell proliferation, whereas NOVH and two other members (ELM1 and RCOP-1) exhibit features of negative regulators of growth. The multimodular structure of these proteins suggests that their biological role(s) may depend on interactions with several factors as well as proteins constitutive of the extracellular matrix. To gain insight into the functionality of these domains, we have used a two-hybrid system to identify proteins interacting with NOVH. We report here that the C-terminal domain confers on the full-length NOVH protein the capacity to bind fibulin 1C, a protein of the extracellular matrix that interacts with several other regulators of cell adhesion. Furthermore, we show that a natural N-truncated isoform of NOVH produced by cells expressing the full-length NOVH protein also binds fibulin 1C with a high affinity, and we hypothesize that the production of truncated isoforms of NOVH (and probably of other CCN proteins) may be a critical aspect in the modulation of their biological activity. These results set the stage for a study of NOVH-fibulin 1C interactions and their potential significance in cell-adhesion signaling in normal and pathological conditions.

Improving simultaneous voice and data performance in Bluetooth systems (2004)

In the Bluetooth system, isochronous applications, such as voice and audio, are carried by synchronous connection oriented (SCO) links. SCO packets are regularly scheduled every two, four, or six time slots and enjoy preemptive priority over data-bearing asynchronous connection-less (ACL) packets. The residual bandwidth available to simultaneous data services is often insufficient for many types of applications, even under perfect channel conditions. We introduce a novel methodology where isochronous audio traffic is carried over ACL links to obtain higher simultaneous data throughputs while strictly adhering to the 64 Kbps isochronous service quality guaranteed by SCO links. Simulation results are presented for a variety of channel conditions verifying that this technique improves both the throughput for data services and the quality of voice services.
Direct interactions between PSD-95 and stargazin control synaptic AMPA receptor number (2002)

Excitatory synapses in the brain exhibit a remarkable degree of functional plasticity, which largely reflects changes in the number of synaptic alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs). However, mechanisms involved in recruiting AMPARs to synapses are unknown. Here we use hippocampal slice cultures and biolistic gene transfections to study the targeting of AMPARs to synapses. We show that AMPARs are localized to synapses through direct binding of the first two PDZ domains of synaptic PSD-95 (postsynaptic density protein of 95 kDa) to the AMPAR-associated protein, stargazin. Increasing the level of synaptic PSD-95 recruits new AMPARs to synapses without changing the number of surface AMPARs. At the same time, we show that stargazin overexpression drastically increases the number of extra-synaptic AMPARs, but fails to alter synaptic currents if synaptic PSD-95 levels are kept constant. Finally, we make compensatory mutations to both PSD-95 and stargazin to demonstrate the central role of direct interactions between them in determining the number of synaptic AMPARs.
