New XMRV Paper Looks Good, Skeptics Admit—Yet Doubts Linger (2010)

This week, a long-awaited paper about the link between a virus and chronic fatigue syndrome (CFS) finally saw the light of day. The study confirms a controversial 2009 paper that reported CFS patients are often infected with the virus, called XMRV.
Association between human cancer and two polymorphisms occurring together in the p21Waf1/Cip1 cyclin-dependent kinase inhibitor gene (1997)

These data suggest that p21 gene variants may play a role in increased susceptibility for the development of some types of cancer. In the current study, the authors demonstrated that the occurrence of these two polymorphisms is increased in prostate adenocarcinoma and squamous cell carcinoma of the head and neck. The polymorphic sites may be directly responsible for this apparent increased susceptibility or they may be linked to regulatory region alterations.
Effects of core retrieval and degassing on the carbon isotope composition of methane in gas hydrate- and free gas-bearing sediments from the Blake Ridge (2000)

A pressurized core with CH 4 hydrate or dissolved CH 4 should evolve gas volumes in a predictable manner as pressure is released over time at isothermal conditions.Incremental gas volumes were collected as pressure was released over time from 29 pressure core sampler (PCS) cores from Sites 994, 995, 996, and 997 on the Blake Ridge.Most of these cores were kept at or near 0°C with an ice bath, and many of these cores yielded substantial quantities of CH 4 .Volume-pressure plots were constructed for 20 of these cores.Only five plots conform to expected volume and pressure changes for sediment cores with CH 4 hydrate under initial pressure and temperature conditions.However, other evidence suggests that sediment in these five and at least five other PCS cores contained CH 4 hydrate before core recovery and gas release.Detection of CH 4 hydrate in a pressurized sediment core through volume-pressure relationships is complicated by two factors.First, significant quantities of CH 4poor borehole water fill the PCS and come into contact with the core.This leads to dilution of CH 4 concentration in interstitial water and, in many cases, decomposition of CH 4 hydrate before a degassing experiment begins.Second, degassing experiments were conducted after the PCS had equilibrated in an ice-water bath (0°C).This temperature is significantly lower than in situ values in the sediment formation before core recovery.Our results and interpretations for PCS cores collected on Leg 164 imply that pressurized containers formerly used by the Deep Sea Drilling Project (DSDP) and currently used by ODP are not appropriately designed for direct detection of gas hydrate in sediment at in situ conditions through volume-pressure relationships.

Transient false tripping characteristic analysis of ground fault circuit interrupter (2005)

GFCI (ground fault circuit interrupter) is widely used to prevent from fire hazards, electronic shock and injury to persons by a persistent earth leakage current. On account of a application of GFCI, however the occurrence of false tripping due to lightning and switching surge has been growing. This unwanted tripping caused by the transient ground potential rise due to nearby lightning strokes could bring about a fatal loss like a power outage or a deterioration of power quality. In order to analyze the cause of malfunction, various samples of GFCI were investigated experimentally. When lightning impulse and EFT (electrical fast transient) were injected to GFCIs with the different leakage current detecting circuits and the wiring configurations, various false tripping characteristics were showed. Most of them showed malfunctions under surge current less than 3 kA. Also, it was found that a false tripping is dependent on a wiring of GFCI circuit and position of protective component Countermeasures using MOV (metal oxide varistor) and zener diode were suggested to prevent from a false tripping in this study.
Terahertz phase modulator (2000)

A semiconductor quantum device which enables the phase modulation of terahertz signals is described. Modulation-doped parabolic quantum wells enable the electronic control of dispersion at terahertz frequencies. Device characterisation with terahertz time-domain spectroscopy shows a phase modulation for frequencies up to 4 THz.
Optical transients in the WASP survey (2010)

This thesis describes a search for transient phenomena using data from the\nWide Angle Search for Planets (WASP) observatories. With images taken of the\nsame region of sky every 15 minutes and a field-of-view of 974 degrees squared,\nthe WASP survey is ideal for identifying both short and long duration transients\nto a limiting magnitude of 16 in V. A high cadence wide-field survey of this type\nhas not been carried out before so provides a different method of sampling variable\npopulations and has the potential to identify previously unknown phenomena.\nAn algorithm to carry out a full untargeted search of the database was developed,\ntested and run on data from 2004, 2006, 2007 and 2008. False positives were\nrejected based on their proximity to similar magnitude stars, the tightness of the\nclustering of detections in sky coordinates, the focus of the images and the number\nof corroborating detections.\nOverall, 44 cataclysmic variable candidates, 144 extreme flare candidates, 63\nvariable star candidates and 57 transients of unknown type were identified. The cataclysmic\nvariable candidates showed similarities to the currently known population\nalthough some selection effects were uncovered. Of particular note were two new WZ\nSge systems, an eclipsing system with a period of 540 minutes and an object with\nan M-star spectrum and broad Balmer lines but no visible white dwarf. The flares\nare some of the largest ever observed on M-type stars. The largest of these released\n~1035erg in the V-band alone. A candidate flare was also identified on a G-type\nstar releasing 1.6×1037erg in the V-band. Alternatively, it may be unrelated to the\nG-star and could be a gamma ray burst or similar transient without a persistent\ncounterpart. A known supernova and two known novae were also identified.
Calcium signaling around Mitochondria Associated Membranes (MAMs) (2011)

Calcium (Ca2+) homeostasis is fundamental for cell metabolism, proliferation, differentiation, and cell death. Elevation in intracellular Ca2+ concentration is dependent either on Ca2+ influx from the extracellular space through the plasma membrane, or on Ca2+ release from intracellular Ca2+ stores, such as the endoplasmic/sarcoplasmic reticulum (ER/SR). Mitochondria are also major components of calcium signalling, capable of modulating both the amplitude and the spatio-temporal patterns of Ca2+ signals. Recent studies revealed zones of close contact between the ER and mitochondria called MAMs (Mitochondria Associated Membranes) crucial for a correct communication between the two organelles, including the selective transmission of physiological and pathological Ca2+ signals from the ER to mitochondria. In this review, we summarize the most up-to-date findings on the modulation of intracellular Ca2+ release and Ca2+ uptake mechanisms. We also explore the tight interplay between ER- and mitochondria-mediated Ca2+ signalling, covering the structural and molecular properties of the zones of close contact between these two networks.

A fault oriented partial scan design approach (2002)

The authors propose a fault oriented partial scan design methodology to be performed as a sequel to test generation. Given the cost of converting each flip-flop to a scanned flip-flop and an overall bound on the cost of the scan design, the program OPUS-2 selects a set of flip-flops which are most likely to improve the quality of test generation. The expected improvement in testability is modeled by profit functions quantifying the reduction in weighted cycles, or the reduction in SCOAP values at hard-to-detect fault sites. Experiments performed on ISCAS89 sequential benchmark circuits show that, by analytically selecting only 10-20% of the flip-flops, the circuits can be tested to the same level of quality as a fully scanned circuit. The advantages of the proposed method are that the highest possible fault coverage can be achieved while limiting the cost of scan to a user-specified limit.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Central Motor Conduction Time to Upper and Lower Limbs in Cervical Cord Lesions (1994)

In extramedullary lesions, measurement of CMCT to the TA is more sensitive. The procedure is valuable in detecting subclinical lesions. Abnormal CMCT correlates with cord compression and clinical signs of upper motor neuron involvement.
A parallel diffusion-based microfluidic device for bacterial chemotaxis analysis (2012)

We developed a multiple-channel microfluidic device for bacterial chemotaxis detection. Some characteristics such as easy operation, parallel sample adding design and fast result readout make this device convenient for most biology labs. The characteristic feature of the design is the agarose gel channels, which serve as a semi-permeable membrane. They can stop the fluid flow and prevent bacteria getting across, but permit the diffusion of small molecules. In the device fabrication process a novel thermal-based method was used to control the shape of agarose gel in the microfluidic channel. The chemical gradient is established by diffusion which can be precisely controlled and measured. Combined with an 8-channel pipette, different attractants, repellent chemicals or different bacteria were analyzed by a two step operation with a readout time of one hour. This device may be useful in the high throughput detection of chemotaxis related molecules and genes.
Revision total elbow arthroplasty. (1987)

Over a ten-year period, thirty-three consecutive revision total elbow arthroplasties were performed at our institution. These were assessed at a minimum of three years after the revision, with an average length of follow-up of sixty-one months. Eighteen (55 per cent) of the elbows had a good result and fifteen (45 per cent) had a poor result. The poor results were due to infection in three elbows, loosening of the prosthesis in six, inadequate motion in two, continued pain in two, and prosthetic failure in two. Additional surgical revision with another implant was done in the fifteen elbows that initially had a poor result. Eventually the result was good in twenty-four elbows. The three elbows that became infected after surgical revision had a resection arthroplasty and all were rated as having a fair result. The data from this study indicated that reimplantation is a viable option for the revision of a failed total elbow arthroplasty, although more than one revision may be required. They also suggested that young patients who have post-traumatic arthritis should not undergo a total joint replacement, and that revision procedures should be performed in settings that can offer several surgical options and by surgeons who have had experience with these options. Alternatives to reimplantation as a revision procedure should be considered in selected patients.
Comparison of Sweep and Dihedral Effects on Compressor Cascade Performance (1997)

The influence of two stacking lines, namely sweep and dihedral, has been investigated in a linear compressor cascade. Both types of blades considered are symmetrical about midspan and consist of a straight central section with either swept or dihedral sections towards the endwalls. Two types of experiments have been carried out. Firstly, a parametric study was performed by changing both the magnitude and the extent of the sweep or dihedral. In the case of swept blades, those with forward sweep (SWF), for which the stacking line is swept in the upstream direction towards the endwall, were found to have better performance than backward swept blades. Subsequently, four sets of SWFs were compared. In the case of dihedral blades, it is well-known that the dihedral is advantageous when the angle between the suction surface and the endwall is obtuse, i.e. positive dihedral. Thus, four sets of positive dihedral blades (DHP) were compared. In both SWF and DHP blades, those configurations which have better efficiency than straight blades were determined. Secondly, detailed three-dimensional measurements inside the blade passage were performed in the cases which showed the best performance in the parametric study. Both SWF and DHP showed significant effects on the flowfield. In the SWF case, a vortex, which has the opposite sense to the passage vortex, was observed in the forward portion inside the blade passage. This vortex supplies high-energy fluid to the endwall region and reduces the corner stall. The secondary flow is greatly reduced. In the DHP, the blade loading was reduced at the endwall and increased at the midspan. Also reduction of the corner stall and the secondary flow was observed.
State-of-the-art hydrogen sulfide control for geothermal energy systems: 1979 (1980)

Existing state-of-the-art technologies for removal of hydrogen sulfide are discussed along with a comparative assessment of their efficiencies, reliabilities and costs. Other related topics include the characteristics of vapor-dominated and liquid-dominated resources, energy conversion systems, and the sources of hydrogen sulfide emissions. It is indicated that upstream control technologies are preferred over downsteam technologies primarily because upstream removal of hydrogen sulfide inherently controls all downstream emissions including steam-stacking. Two upstream processes for vapor-dominated resources appear promising; the copper sulfate (EIC) process, and the steam converter (Coury) process combined with an off-gas abatement system such as a Stretford unit. For liquid-dominated systems that produce steam, the process where the non-condensible gases are scrubbed with spent geothermal fluid appears to be promising. An efficient downstream technology is the Stretford process for non-condensible gas removal. In this case, partitioning in the surface condenser will determine the overall abatement efficiency. Recommendations for future environmental control technology programs are included.
An integrated design of power converters for electric vehicles (2017)

This paper proposes a novel integrated power system for electric vehicles (EVs) to improve the power density and efficiency at a less cost. It integrates the on-board charger (OBC) and the low-voltage DC/DC converter (LDC) by common use of semiconductor devices, capacitors and magnetic components. Therefore, the volume and cost of the integrated system is reduced compared with the conventional two independent converters. The proposed system can operate in three modes: OBC standalone mode, LDC standalone mode and OBC-LDC simultaneous mode. The phase-shift control is the main control strategy for this system. For a light load, a PWM plus phase shift (PPS) control is added to provide expending soft switching range. As the most important integrated component, the transformer is designed by considering the soft switching ranges. The theoretical analysis of topology, operating modes, control strategy and transformer design are presented. A prototype integrating a 3.3-kW OBC and a 2-kW LDC is built to demonstrate the validity and advantages of the proposed system.
Mat-core: a decoupled matrix core extension for general-purpose processors (2011)

This paper proposes new processor architecture to exploit the increasingly number of transistors per integrated circuit and improve the performance of many applications on general-purpose processors. The proposed processor (called Mat-Core) is based on the use of multi-level ISA to explicitly communicate data parallelism to processor in a compact way instead of the dynamic extraction using complex hardware or the static extraction using sophisticated compiler techniques. Scalar-scalar (level-O), scalar-vector (level-l), vector-vector (level-l), vector-matrix (level-2), and matrix-matrix (level-3) instruction sets are used as a multi-level interface between hardware and software. Mat-Core extends a general-purpose scalar processor (for executing scalar instructions) with a matrix unit (for executing vector/matrix instructions). To tolerate the memory latency, the extended matrix unit is decoupled into two components: address generation and data computation. The data computation unit is organized in parallel lanes; each lane contains a pipeline of each functional unit and a slice of the matrix register file. On parallel lanes, the Mat-Core processor can effectively process not only vector but also matrix data. This paper explains the execution of vector/matrix instructions on the parallel lanes of Mat-Core. Moreover, the performances of element-wise vector-vector addition, vector-matrix multiplication, and matrix-matrix multiplication are estimated on the decoupled Mat-Core processor. The increasingly budget of transistors can be exploiting to scale the Mat-core processor by providing more cores in a physical package. On a Multi-Mat-Core processor, performance would be improved by parallel processing threads of codes using multi-threading techniques.
Learning in efficient tag recommendation (2010)

The objective of a tag recommendation system is to propose a set of tags for a resource to ease the tagging process done manually by a user. Tag recommendation is an interesting and well defined research problem. However, while solving it, it is easy to forget about its practical implications. We discuss the practical aspects of tag recommendation and propose a system that successfully addresses the problem of learning in tag recommendation, without sacrificing efficiency. Learning is realized in two aspects: adaptation to newly added posts and parameter tuning. The content of each added post is used to update the resource and user profiles as well as associations between tags. Parameter tuning allows the system to automatically adjust the way tag sources (e.g., content related tags or user profile tags) are combined to match the characteristics of a specific collaborative tagging system. The evaluation on data from three collaborative tagging systems confirmed the importance of both learning methods. Finally, an architecture based on text indexing makes the system efficient enough to serve in real time collaborative tagging systems with number of posts counted in millions, given limited computing resources.
Scattering by a dielectric cylinder of arbitrary cross section shape (1965)

The theory and equations are developed for the scattering pattern of a dielectric cylinder of arbitrary cross section shape. The harmonic incident wave is assumed to have its electric vector parallel with the axis of the cylinder, and the field intensities are assumed to be independent of distance along the axis. Solutions are readily obtained for inhomogeneous cylinders when the permittivity is independent of distance along the cylinder axis. Although other investigators have approximated the field within the dielectric body by the incident field, we treat the total field as an unknown function which is determined by solving a system of linear equations. In the case of the dielectric cylindrical shell of circular cross section, this technique yields results which agree accurately with the exact classical solution. Scattering patterns are also presented in graphical form for a dielectric shell of semicircular cross section, a thin homogeneous plane dielectric sheet of finite width, and an inhomogeneous plane sheet. The effects of surface-wave excitation and mutual interaction among the various portions of the dielectric shell are included automatically in this solutiom
An architecture for visualizing the execution of parallel logic programs (1991)

This paper describes the development of an architecture and implementation of a graphical tracing system for the parallel logic programming language PARLOG. Novel features of the architecture include a graphical execution model of PARLOG; a range of representational techniques that allow the user a choice of perspective and granularity of analysis; and ongoing work on graphical tools that provide user-defined visualisations of their programs, either before the program is run, or afterwards by demonstration from a textual trace. The aims of the architecture are threefold: (1) to aid program construction and debugging by providing an informative graphical trace of the program's execution; (2) to provide the user with a choice of representational techniques, at a preferred level of granularity; and (3) to allow users to define their own visualisations, that more truly map onto their conception of the problem, and which support the way they wish to view the execution information.
