Articulated mesh animation from multi-view silhouettes (2008)

Details in mesh animations are difficult to generate but they have great impact on visual quality. In this work, we demonstrate a practical software system for capturing such details from multi-view video recordings. Given a stream of synchronized video images that record a human performance from multiple viewpoints and an articulated template of the performer, our system captures the motion of both the skeleton and the shape. The output mesh animation is enhanced with the details observed in the image silhouettes. For example, a performance in casual loose-fitting clothes will generate mesh animations with flowing garment motions. We accomplish this with a fast pose tracking method followed by nonrigid deformation of the template to fit the silhouettes. The entire process takes less than sixteen seconds per frame and requires no markers or texture cues. Captured meshes are in full correspondence making them readily usable for editing operations including texturing, deformation transfer, and deformation model learning.
Tensile Properties of Films from Low-Temperature GR-S Latex (1954)

Abstract Studies were made of the influence of a number of polymerization variables on the tensile strength of vulcanized evaporated films from low-temperature high-solids GR-S latexes. Previous reports of film tensiles on the order of 3000 pounds per square inch for latexes of 70/30 butadiene-styrene charge ratio were confirmed. The levels of accelerator necessary for optimum vulcanized properties were found to be considerably lower than those normally used, particularly for latexes shortstopped with dithiocarbamate salts. Microscopic coagulum found in some latex samples had a pronounced effect in decreasing film tensile of vulcanizates. Cured films from latexes emulsified with mixtures of fatty acid and rosin soap possessed considerably better tensile strengths than those from latexes using all fatty acid soap emulsification. Wide variations on Mooney viscosity had relatively little effect on ultimate film tensiles. Incorporation of small amounts of lignin into the latex as the ammonium or sodium salt decreased cure rates of films and aided in giving more reproducible tensile results. Both lignin and the sodium salt of cresyl monosulfide improved the aging characteristics of films.
A neuroinductive biomaterial based on dopamine (2006)

Chemical messengers such as neurotransmitters play an important role in cell communication, differentiation, and survival. We have designed and synthesized a bioactive biomaterial that derived its biological activity from dopamine. The resultant biodegradable polymer, PCD, has pendent groups bearing dopamine functionalities. Image analysis demonstrated that nerve growth factor-primed rat pheochromocytoma cells (PC12) and explanted rat dorsal root ganglions attached well and displayed substantial neurite outgrowth on the polymer surface. Furthermore, PCD promoted more vigorous neurite outgrowth in PC12 cells than tissue culture polystyrene, laminin, and poly(d-lysine). The histogram of neurite length of PC12 cells showed distinctive patterns on PCD that were absent on the controls. A subset of PC12 cells displayed high filopodium density on PCD. The addition of dopamine in culture medium had little effect on the differentiation of PC12 cells on tissue culture polystyrene. Tyrosine, the precursor of dopamine, did not exhibit this ability to impart specific bioactivity to an analogous polymer. Thus, the dopamine functional group is likely the origin of the inductive effect. PCD did not cause nerve degeneration or fibrous encapsulation when implanted immediately adjacent to the rat sciatic nerves. This work is a step toward creating a diverse family of bioactive materials using small chemical messengers as monomers.
Grouping Proof for RFID Tags (2005)

An RFID tag is a small and cheap device which is combined in IC chip and an antenna for radio communications. The tag is used for management of goods and its distribution. Moreover it reduces the cost of managements of goods. However, an RFID system has some security problems. Juels proposed a "yoking-proof" which guarantees the existence of two tags (Juels, 2004). But we point out that this scheme is not secure against a replay attack. In this paper, we propose a scheme which deals with the problem by using time stamp. Moreover, we propose a scheme which guarantees the existence of a group of RFID tags.
Tuning a PID Controller for a Digital Excitation Control System (2005)

Some of the modern voltage regulator systems are utilizing the proportional, integral, and derivative (PID) control for stabilization. Two PID tuning approaches, pole placement and pole-zero cancellation, are commonly utilized for commissioning a digital excitation system. Each approach is discussed including its performance with three excitation parameter variations. The parameters considered include system loop gain, uncertain exciter time constants, and forcing limits. This paper is intended for various engineers and technicians to provide a better understanding of how the digital controller is tuned with pros and cons for each method.
The Human Gene Mutation Database: 2008 update (2009)

The Human Gene Mutation Database (HGMD((R))) is a comprehensive core collection of germline mutations in nuclear genes that underlie or are associated with human inherited disease. Here, we summarize the history of the database and its current resources. By December 2008, the database contained over 85,000 different lesions detected in 3,253 different genes, with new entries currently accumulating at a rate exceeding 9,000 per annum. Although originally established for the scientific study of mutational mechanisms in human genes, HGMD has since acquired a much broader utility for researchers, physicians, clinicians and genetic counselors as well as for companies specializing in biopharmaceuticals, bioinformatics and personalized genomics. HGMD was first made publicly available in April 1996, and a collaboration was initiated in 2006 between HGMD and BIOBASE GmbH. This cooperative agreement covers the exclusive worldwide marketing of the most up-to-date (subscription) version of HGMD, HGMD Professional, to academic, clinical and commercial users.
Nanoalloy Printed and Pulse-Laser Sintered Flexible Sensor Devices with Enhanced Stability and Materials Compatibility (2015)

While conformal and wearable devices have become one of the most desired formats for printable electronics, it is challenging to establish a scalable process that produces stable conductive patterns but also uses substrates compatible with widely available wearable materials. Here, we describe findings of an investigation of a nanoalloy ink printed and pulsed-laser sintered conductive patterns as flexible functional devices with enhanced stability and materials compatibility. While nanoparticle inks are desired for printable electronics, almost all existing nanoparticle inks are based on single-metal component, which, as an electronic element, is limited by its inherent stabilities of the metal such as propensity of metal oxidation and mobility of metal ions, especially in sintering processes. The work here has demonstrated the first example in exploiting plasmonic coupling of nanoalloys and pulsed-laser energy with controllable thermal penetration. The experimental and theoretical results have revealed clear correlation between the pulsed laser parameters and the nanoalloy structural characteristics. The superior performance of the resulting flexible sensor device, upon imparting nanostructured sensing materials, for detecting volatile organic compounds has significant implications to developing stable and wearable sensors for monitoring environmental pollutants and breath biomarkers. This simple "nanoalloy printing-laser sintering-nanostructure printing" process is entirely general to many different sensor devices and nanostructured sensing materials, enabling the ability to easily construct sophisticated sensor array.
The DNA-encoded nucleosome organization of a eukaryotic genome (2008)

Nucleosome organization is critical for gene regulation. In living cells this organization is determined by multiple factors, including the action of chromatin remodellers, competition with site-specific DNA-binding proteins, and the DNA sequence preferences of the nucleosomes themselves. However, it has been difficult to estimate the relative importance of each of these mechanisms in vivo, because in vivo nucleosome maps reflect the combined action of all influencing factors. Here we determine the importance of nucleosome DNA sequence preferences experimentally by measuring the genome-wide occupancy of nucleosomes assembled on purified yeast genomic DNA. The resulting map, in which nucleosome occupancy is governed only by the intrinsic sequence preferences of nucleosomes, is similar to in vivo nucleosome maps generated in three different growth conditions. In vitro, nucleosome depletion is evident at many transcription factor binding sites and around gene start and end sites, indicating that nucleosome depletion at these sites in vivo is partly encoded in the genome. We confirm these results with a micrococcal nuclease-independent experiment that measures the relative affinity of nucleosomes for approximately 40,000 double-stranded 150-base-pair oligonucleotides. Using our in vitro data, we devise a computational model of nucleosome sequence preferences that is significantly correlated with in vivo nucleosome occupancy in Caenorhabditis elegans. Our results indicate that the intrinsic DNA sequence preferences of nucleosomes have a central role in determining the organization of nucleosomes in vivo.
Ti/Al/Ni/Au Ohmic Contacts on AlGaN/GaN HEMTs (2003)

The purpose of this study was to construct a HA-1-DC nucleic acid vaccine and to induce anti-leukemia effect after hematopoietic stem cell transplantation (HSCT). The dendritic cells (DCs) were generated from HSCT donors in vitro, and its immunologic activity was studied by using flow cytometry and mix lymphocyte reaction. HA-1 gene was electroporated into the cultured DCs to construct a DC nucleic acid vaccine. After transfecting for 48 hours, the expression of HA-1 protein was detected by Western blot. The DCs were cultured with isogenic lymphocytes to induce specific cytotoxic T lymphocytes (CTLs). The cytotoxicity of the CTLs was detected by LDH assay. The results showed that the DCs derived from peripheral blood monocytes (PBMCs) expressed the DC phenotype, and were effective in stimulating proliferation of the allogenic lymphocytes. After electroporating for 48 hours, HA-1 protein was detected by Western blot. The cytotoxity of inducing CTLs was higher than that in the control group. It is concluded that the minor histocompatibility antigen HA-1 can be considered as a target of immunotherapy against leukemia after HSCT.
Saturation Adjustment Scheme of Blind Color Watermarking for Secret Text Hiding (2010)

This paper presents a novel secret text hiding technique, where the secret text is embedded into the low frequency sub-band of the saturation component of a color image via redundant discrete wavelet transform (RDWT), while the intensity and hue components are preserved with direct saturation adjustment. The hidden secret text can be extracted from the watermarked image based on independent component analysis (ICA) without referring to the original cover image. Experimental results demonstrate that our scheme successfully fulfills the requirement of imperceptibility and provides sufficient robustness to against the most prominent attacks, such as JPEG2000, JPEG-loss compression, low-pass filtering, scaling, and cropping.
Thrombocytopenia in Critically Ill Patients (2008)

Critically ill patients often have a low platelet count. A proper identification of the underlying cause of this abnormality is required, because various underlying disorders may necessitate different diagnostic and therapeutic management strategies. Platelets are part of the first line of defense of the body against bleeding, hence, thrombocytopenia may increase the risk of hemorrhage. In case of systemic inflammatory syndromes, such as the response to sepsis, disseminated intravascular platelet activation may occur, which will contribute to microvascular failure and thereby play a role in the development of organ dysfunction. A low platelet count is a strong and independent predictor of an adverse outcome in critically ill patients, thereby facilitating a simple and practical risk assessment in these patients and potentially guiding the use of complex or expensive treatment strategies.
The readout thickness versus the measured thickness for a range of screen film mammography and full-field digital mammography units (2011)

None of the units assessed were found to have perfect correlation between measured and readout thickness. TMD measures and thickness readouts were different for the duplicate units from two different models/manufacturers.
A Model of Search Intermediaries and Paid Referrals (2007)

In this paper we pursue three main objectives: (1) to develop a model of an intermediated search market in which matching between consumers and firms takes place primarily via paid referrals; (2) to address the question of designing a suitable mechanism for selling referrals to firms; and (3) to characterize and analyze the firms' bidding strategies given consumers' equilibrium search behavior. To achieve these objectives we develop a two-stage model of search intermediaries in a vertically differentiated product market. In the first stage an intermediary chooses a search engine design that specifies to which extent a firm's search rank is determined by its bid and to which extent it is determined by the product offering's performance. In the second stage, based on the search engine design, competing firms place their open bids to be paid for each referral by the search engine. We find that the revenue-maximizing search engine design bases rankings on a weighted average of product performance and bid amount. Nonzero pure-strategy equilibria of the underlying discontinuous bidding game generally exist but are not robust with respect to noisy clicks in the system. We determine a unique nondegenerate mixed-strategy Nash equilibrium that is robust to noisy clicks. In this equilibrium firms of low product performance fully dissipate their rents, which are appropriated by the search intermediary and the firm with the better product. The firms' expected bid amounts are generally nonmonotonic in product performance and depend on the search engine design parameter. The intermediary's profit-maximizing design choice, by attributing a positive weight to the firms' bids, tends to obfuscate search results and reduce overall consumer surplus compared to the socially optimal design of fully transparent results ranked purely on product performance.
Intensity modulated radiation therapy: a clinical review. (2000)

Intensity modulated radiotherapy represents a significant advance in conformal radiotherapy. In particular, it allows the delivery of dose distributions with concave isodose profiles such that radiosensitive normal tissue close to, or even within a concavity of, a tumour may be spared from radiation injury. This article reviews the clinical application of this technique to date, and discusses the practical issues of treatment planning and delivery from the clinician's perspective.
Breast cancer multicentricity. (1984)

The reported incidence of breast cancer multicentricity has varied depending on the methods selected for sampling the apparently uninvolved portion of the breast, the distance a second cancer must be from the first cancer in order for it to be considered multicentric, and whether or not in situ carcinomas are included in calculations of multicentricity. In addition, the incidence of multicentricity may depend to some extent on the pathological stage and other histological characteristics of the primary index cancer. Bearing these various considerations in mind, one may estimate the overall rate of breast cancer multicentricity to be in the range of 25-50%. It also would appear that at least 5-10% of these multicentric cancers are invasive. Multicentric cancers do not appear limited to the breast quadrant that contains the primary index tumor, and they frequently involve breast tissue immediately subjacent to the nipple. In view of this incidence of multicentricity, if a breast cancer is treated by tylectomy one may predict that there will be a significant number of recurrences in the ipsilateral breast, although considerable time may be required before these additional breast cancers become clinically apparent. Whether or not recurrences of this type will increase breast cancer mortality is not known. Available data suggests that appropriate radiation to the apparently uninvolved portion of the breast may significantly reduce the chance of relatively short term recurrence. The effect of combining breast irradiation or adjuvant chemotherapy with tylectomy on long term survival is not known.
Giant Magnetoresistance Materials And Their Potential As Read Head Sensors (2005)

The physical origins of the giant magnetoresistance (GMR) phenomenon is briefly reviewed, and the magnitudes of the GMR ratios in multilayers, spin values, and granular alloys is reviewed. It is pointed out that, though spin valves have been the leading candidate for sensor materials, the maximum values of the sensor sensitivity dR/dH achieved in spin valves are modest. Multilayers can have enormous values of /spl Delta/R/R, but are not presently realistic sensor candidates because of their large saturation fields. Arguments are made that interlayer exchange may be manipulable and attractive sensor arrays synthesized. Recent developments in pancake/multilayer granular alloys are presented, NiFe-Ag systems which display a small saturation field and very attractive values of dR/dH. The conclusion is drawn that GMR sensors will be important in read head technology in the near future. >
Electronic states in amorphous metals (1979)

The electronic states in a model amorphous metal (dense random packing hard-sphere model) are studied in the cases of orthogonal and nonorthogonal atomic orbitals. Compared to the infinite FCC crystal, the density of states shows relatively small change in the bandwidth and the L point singularity seems to be preserved. Peak positions are, however, seen to shift towards the lower-energy side. A 'roton' like behaviour in the wave vector-dependent spectra is also found. These features are discussed in detail by comparison with the FCC case.
Enhancement of the Immunogenicity of Synthetic Carbohydrate Vaccines by Chemical Modifications of STn Antigen (2010)

The abnormal glycans expressed on the surface of tumor cells, known as tumor-associated carbohydrate antigens, increase the chance to develop carbohydrate-based anticancer vaccines. However, carbohydrate antigens pose certain difficulties, and the major drawback is their weak immunogenicity. To tackle this problem, numerous structurally modified STn antigens were designed and synthesized in this work. These synthetic antigens were screened in vitro by using competitive ELISA method, and the antigens with positive response were conjugated to the protein carrier for vaccination. The vaccination results on mice showed that some fluorine-containing modifications on the STn antigen can significantly increase the anti-STn IgG titers and improve the ratios of anti-STn IgG/IgM. The antisera can recognize the tumor cells expressing the native STn antigen.
Design and evaluation of benchmarks for financial applications using Advanced Message Queuing Protocol (AMQP) over InfiniBand (2008)

Message Oriented Middleware (MOM) is a key technology in financial market data delivery. In this context we study the Advanced Message Queuing Protocol (AMQP), an emerging open standard for MOM communication. We design a basic suite of benchmarks for AMQP’s Direct, Fanout, and Topic Exchange types. We then evaluate these benchmarks with Apache Qpid, an open source implementation of AMQP. In order to observe how AMQP performs in a real-life scenario, we also perform evaluations with a simulated stock exchange application. All our evaluations are performed over InfiniBand as well as 1 Gigabit Ethernet networks. Our results indicate that in order to achieve the high scalability requirements demanded by high performance computational finance applications, we need to use modern communication protocols, like RDMA, which place less processing load on the host. We also find that the centralized architecture of AMQP presents a considerable bottleneck as far as scalability is concerned.

Design correctness of digital systems (2002)

Transformational design is a formal technique directed at design correctness. It integrates design and verification by the use of pre-proven behaviour preserving transformations as design steps. A formal framework is necessary but hidden for the designer. Five formal aspects are integrated in the presented formal framework that is aimed at the design of complex systems composed out of different kinds of subsystems. The tagged signal model is used as 'meta' model for a heterogeneous set of computational models with different concurrency semantics. The offered possibilities of model refinement by transformations and the ability to incorporate heterogeneity are valuable extensions with respect to other transformational design approaches for high-level synthesis.

Magnetically Suspended Rotary Blood Pump with Radial Type Combined Motor‐Bearing (2000)

A magnetically suspended centrifugal blood pump is being developed with a combined motor-bearing for long-term ventricular assist systems. The combined motor-bearing actively suspends a rotor in a radial direction to deal with radial force unbalance in the pump and rotates the rotor by using the electric magnetic field. Therefore, the pump has no mechanical parts such as bearings of the motor and has a long lifetime. The developed pump consists of a thin rotor with a semi open-type 6 vane impeller and a stator to suspend and rotate the rotor. The rotor has 4-pole permanent magnets on the circumferential surface. The outer diameter and the thickness of the rotor are 60 mm and 8 mm, respectively. Axial movement and tilt of the rotor are restricted by passive stability based on the thin rotor structure. Radial movements of the rotor, such as levitation in radial direction and rotation, are controlled actively by using electric magnets of the stator. The electric magnet coils to produce levitation and rotation forces are constructed on the periphery stator. The p +/- 2-pole algorithm and the synchronous motor mechanism are adopted to levitate and rotate the rotor. The radial gap between the rotor and the stator is 1 mm. A closed-loop circuit filled with water was connected to the developed pump to examine the basic performance of the pump and the magnetic suspension system. Maximum rotational speed, flow rate, and head were 2,800 rpm, 11 L/min, and 270 mm Hg, respectively. The rotor with the impeller could be suspended completely during the entire pumping process. We conclude the pump with the combined motor-bearing has sufficient performance for the blood pump.
