Amyloid of the prion domain of Sup35p has an in-register parallel β-sheet structure (2006)

The [PSI(+)] prion of Saccharomyces cerevisiae is a self-propagating amyloid form of Sup35p, a subunit of the translation termination factor. Using solid-state NMR we have examined the structure of amyloid fibrils formed in vitro from purified recombinant Sup35(1-253), consisting of the glutamine- and asparagine-rich N-terminal 123-residue prion domain (N) and the adjacent 130-residue highly charged M domain. Measurements of magnetic dipole-dipole couplings among (13)C nuclei in a series of Sup35NM fibril samples, (13)C-labeled at backbone carbonyl sites of Tyr, Leu, or Phe residues or at side-chain methyl sites of Ala residues, indicate intermolecular (13)C-(13)C distances of approximately 0.5 nm for nearly all sites in the N domain. Certain sites in the M domain also exhibit intermolecular distances of approximately 0.5 nm. These results indicate that an in-register parallel beta-sheet structure underlies the [PSI(+)] prion phenomenon.

Hardware-in-the-loop (HIL) test systems for unmanned aerial vehicles (UAV) embedded flight controllers provides more realistic test environments for pre-flight tests. The HIL test system which is described in this paper combines a detailed and sophisticated flight simulation software with a moving hardware platform in the pitch and roll axis with actual flight sensors to form a complete testing environment.
Virtual Worlds: No Interface to Design (1991)

In a virtual world, we are inside an environment of pure information that we can see, hear, and touch. The technology itself is invisible, and carefully adapted to human activity so that we can behave naturally in this artificial world. We can create any imaginable environment and we can experience entirely new perspectives and capabilities within it. A virtual world can be informative, useful, and fun, it can also be boring and uncomfortable. The difference is in the design. The platform and the interactive devices we use, the software tools and the purpose of the environment are all elements in the design of virtual worlds. But the most important component in designing comfortable, functional worlds is the person inside them. Cyberspace technology couples the functions of the computer with human capabilities. This requires that we tailor the technology to people, and refine the fit to individuals. We then have customized interaction with personalized forms of information that can amplify our individual intelligence and broaden our experience. Designing virtual worlds is a challenging departure from traditional interface design. In the first section of this chapter I differentiate between paradigms for screen-based interface design and paradigms for creating virtual worlds. The engineer, the designer, and the participant co-create cyberspace. Each role carries its own set of goals and expectations, its own model of the technology's salient features. In the second section of the chapter I address these multiple perspectives, and how they interrelate in the cooperative design process. In conclusion, I consider broader design issues, including control, politics, and emergent phenomena in cyberspace.
Lossless, near-lossless, and refinement coding of bilevel images (1999)

We present general and unified algorithms for lossy/lossless coding of bilevel images. The compression is realized by applying arithmetic coding to conditional probabilities. As in the current JBIG standard the conditioning may be specified by a template. For better compression, the more general free tree may be used. Loss may be introduced in a preprocess on the encoding side to increase compression. The primary algorithm is a rate-distortion controlled greedy flipping of pixels. Though being general, the algorithms are primarily aimed at material containing half-toned images as a supplement to the specialized soft pattern matching techniques that work better for text. Template based refinement coding is applied for lossy-to-lossless refinement. Introducing only a small amount of loss in half-toned test images, compression is increased by up to a factor of four compared with JBIG. Lossy, lossless, and refinement decoding speed and lossless encoding speed are less than a factor of two slower than JBIG. The (de)coding method is proposed as part of JBIG2, an emerging international standard for lossless/lossy compression of bilevel images.

Pattern-directed reporting tool with two-phase outputs (2010)

Reporting Tool is one of the most prevalent applications in diversified fields. Most of the available commercial reporting tools often provide overabundant functions with complicated operating procedures, while users emphasis on ease of use and generation efficiency. Accordingly, we are presenting a pattern-directed design mode, in which a report can be designed by recombining reusable report elements. It will free users from the tuff design and thus greatly facilitate usability. Besides, a mid format is proposed to boost the two-phase outputs in runtime.
Analysis of Interstrain Variation in Cytomegalovirus Glycoprotein B Sequences Encoding Neutralization-Related Epitopes (1991)

Nucleotide sequences of a part of the envelope glycoprotein B (gB) gene of human cytomegalovirus (CMV), encoding epitopes recognized by virus-neutralizing monoclonal antibodies, were determined for 12 distinct clinical strains of CMV after amplification of suitable templates using the polymerase chain reaction. Sequence analysis of this region (codons 384-717) revealed that the clinical strains and previously sequenced laboratory strains Towne and AD169 belong to one of four variant groups, each with a characteristic nucleotide and peptide sequence. Peptide homology was greater than 99% for strains within a group, and varied from 91% to 98% for strains in different groups. Variation was most frequent between codons 448 and 480. The gB group of a CMV strain could be determined by restriction analysis of a small target sequence amplified from viral genomic DNA, and an additional 28 clinical strains were grouped in this manner. The existence of a limited number of variants of gB among clinical strains facilitates analysis of biologic function and cross-reactivity of immune responses.
SMaRTCaR: An integrated smartphone-based platform to support traffic management applications (2012)

A massive research effort is recently going in the direction of interfacing cars with smartphones to offer value-added services to driver and passengers. Such an interest is motivated by the large popularity of smartphones and by the observation that vehicles can act as effective collectors of information from the surrounding environment. Indeed, modern cars are endowed with several sensors forming an in-vehicle network, which provides kinematics information, automotive diagnostic services, etc. Cars can be further equipped with external sensing devices to monitor specific physical parameters, such as pollution, humidity, temperature, etc. If properly collected and delivered, such data can contribute to make the road transport greener, smarter, and safer. With the purpose of supporting and improving data collection and distribution, in this paper a smartphone-based platform is designed that exploits low-cost dedicated hardware to interact with sensors on board and in the vehicle surroundings. Retrieved data are classified and then opportunistically transmitted via the most convenient wireless interface to the specific remote control and monitoring center. A prototype is also developed to assess the technological feasibility of our conceived platform.
A microelectromechanical accelerometer fabricated using printed circuit processing techniques (2007)

A microelectromechanical systems (MEMS) capacitive-type accelerometer fabricated using printed circuit processing techniques is presented. A Kapton polymide film is used as the structural layer for fabricating the MEMS accelerometer. The accelerometer proof mass along with four suspension beams is defined in the Kapton polyimide film. The proof mass is suspended above a Teflon substrate using a spacer. The deflection of the proof mass is detected using a pair of capacitive sensing electrodes. The top electrode of the accelerometer is defined on the top surface of the Kapton film. The bottom electrode is defined in the metallization on the Teflon substrate. The initial gap height is determined by the distance between the bottom electrode and the Kapton film. For an applied external acceleration (normal to the proof mass), the proof mass deflects toward or away from the fixed bottom electrode due to inertial force. This deflection causes either a decrease or increase in the air-gap height thereby either increasing or decreasing the capacitance between the top and the bottom electrodes. An example PCB MEMS accelerometer with a square proof mass of membrane area 6.4 mm × 6.4 mm is reported. The measured resonant frequency is 375 Hz and the Q-factor in air is 0.52.

Stress response during development predicts fitness in a wild, long lived vertebrate (2007)

Short-term elevation of circulating glucocorticosteroids (GCs) in vertebrates facilitates the adoption of a distinct emergency life history state, which allows individuals to cope with perturbations and recover homeostasis at the expense of temporarily suppressing nonessential activities. Although GC responses are viewed as a major evolutionary mechanism to maximize fitness through stress management, phenotypic variability exists within animal populations, and it remains unclear whether interindividual differences in stress physiology can explain variance in unequivocal components of fitness. We show that the magnitude of the adrenocortical response to a standardized perturbation during development is negatively related to survival and recruitment in a wild population of long lived birds. Our results provide empirical evidence for a link between stress response, not exposure to stressors, and fitness in a vertebrate under natural conditions. Recent studies suggest that variability in the adrenocortical response to stress may be maintained if high and low GC responders represent alternative coping strategies, with differential adaptive value depending on environmental conditions. Increased fitness among low GC responders, having a proactive personality, is predicted under elevated population density and availability of food resources, conditions that characterize our study population.
A circle-based vectorization algorithm for drawings with shadows (2013)

Vectorization algorithms described in the literature assume that the drawings being vectorized are either binary images or have a clear white background. Sketches of artistic objects however also contain shadows which help the artist to portray intent, particularly in potentially ambiguous sketches. Such sketches are difficult to binarise since the shading strokes make these sketches non bimodal. For this reason, we describe a circle-based vectorization algorithm that uses signatures obtained from sample points on the line strokes to identify and vectorize the line strokes in the sketch. We show that the proposed algorithm performs as well as other vectorization techniques described in the literature, despite the shadows present in the sketch.

T-S fuzzy control for a class of networked control system (2012)

In this paper, we will propose the T-S fuzzy controller design for a class of networked control system (NCS) with the network transmission delay and the data packet dropout. In the NCS, the controlled plant is approximated to the Takagi-Sugeno fuzzy model (T-S fuzzy model). Then, we propose the fuzzy controller design based on the T-S fuzzy model, to inhibit the effect of the network transmission delay and the data packet dropout, and to guarantee the stability of the overall system. Next, we analyze the stability and the robustness of the overall system by the Lyapunov-Krasovskii function and the Lyapunov stability theorem, and obtain the Lyapunov stability criterion. After that, the Lyapunov stability criterion would be presented in the linear matrix inequality format to solve the control problem more efficiently by using the Schur complements. Finally, the computer simulations are given to demonstrate the validity and the performance of the proposed control strategy.

Zr/ZrO<sub>2</sub> Sensors for in Situ Measurement of pH in High-Temperature and -Pressure Aqueous Solutions (2008)

The aim of this study is to develop new pH sensors that can be used to test and monitor hydrogen ion activity in hydrothermal conditions. A Zr/ZrO2 oxidation electrode is fabricated for in situ pH measurement of high-temperature aqueous solutions. This sensor responds rapidly and precisely to pH over a wide range of temperature and pressure. The Zr/ZrO2 electrode was made by oxidizing zirconium metal wire with Na2CO3 melt, which produced a thin film of ZrO2 on its surface. Thus, an oxidation-reduction electrode was produced. The Zr/ZrO2 electrode has a good electrochemical stability over a wide range of pH in high-temperature aqueous solutions when used with a Ag/AgCl reference electrode. Measurements of the Zr/ZrO2 sensor potential against a Ag/AgCl reference electrode is shown to vary linearly with pH between temperatures 20 and 200 degrees C. The slope of the potential versus pH at high temperature is slightly below the theoretical value indicated by the Nernst equation; such deviation is attributed to the fact that the sensor is not strictly at equilibrium with the solution to be tested in a short period of time. The Zr/ZrO2 sensor can be calibrated over the conditions that exist in the natural deep-seawater. Our studies showed that the Zr/ZrO2 electrode is a suitable pH sensor for the hydrothermal systems at midocean ridge or other geothermal systems with the high-temperature environment. Yttria-stabilized zirconia sensors have also been used to investigate the pH of hydrothermal fluids in hot springs vents at midocean ridge. These sensors, however, are not sensitive below 200 degrees C. Zr/ZrO2 sensors have wider temperature range and can be severed as good alternative sensors for measuring the pH of hydrothermal fluids.
Ceramics for Total Hip Replacement - What a Surgeon Should Know (1998)

Numerous clinical results reported in the literature prove that ceramic femoral heads reduce wear, osteolysis, and revision rates in total hip replacements (THRs). Femoral heads and cups made out of alumina ceramics were introduced about 25 years ago, and femoral heads made out of zirconia were introduced about 10 years ago. Today, the wear couples of alumina-on-polyethylene or zirconia-on-polyethylene have become the standard in THR. The wear couple offering the lowest wear rate is alumina-on-alumina. This article discusses the state of the art and lists advantages as well as problems with the various materials used for prostheses in THR.
Gene Signature Is Associated with Early Stage Rectal Cancer Recurrence (2010)

Dielectric properties of bismuth layer type ceramics with lanthanum and nickel co-substitutions (2003)

The dielectric properties of bismuth-layer-type ceramics with lanthanum and nickel cosubstitutions, Bi/sub 2/(Pb/sub 1-x/La/sub x/)(Nb/sub 2-x/3/Ni/sub x/3/)O/sub 9/ are presented. Above the Curie temperature, the dielectric constant decreases at a rate that can be approximately described by Smolensky's quadratic law, showing relaxor behavior. At room temperature, the dielectric constant and loss tangent of the new materials are higher than those of the parent Bi/sub 2/PbNb/sub 2/O/sub 9/. High resistivity and breakdown strength make these materials very attractive for applications such as a high-voltage ceramic capacitor dielectric.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Receptor-Mediated Actions of Corticotropin-Releasing Factor in Pituitary Gland and Nervous System (1986)

High-affinity corticotropin-releasing factor (CRF) receptors which mediate the actions of the hypothalamic peptide on adrenocorticotropic hormone (ACTH) release have been identified in the rat anterior pituitary gland. Occupancy of the pituitary receptor by CRF agonists stimulates ACTH release via activation of adenylate cyclase and cyclic adenosine monophosphate dependent protein kinase. In the regulation of ACTH secretion, the effects of CRF on the corticotroph are integrated with the stimulatory actions of cyclic adenosine monophosphate-independent stimuli such as angiotensin II, vasopressin and norepinephrine, and the inhibitory effects of glucocorticoids and somatostatin. In contrast to the major importance of the inhibitory effect of glucocorticoid feedback on ACTH secretion, somatostatin has relatively little effect on CRF-stimulated ACTH release in the normal rat corticotroph. Following adrenalectomy, the progressive elevation of plasma ACTH levels is accompanied by a concomitant decrease in pituitary CRF receptors. The postadrenalectomy loss of CRF receptors, which is prevented by dexamethasone treatment, is caused by a combination of occupancy and processing of the pituitary sites during increased secretion of the hypothalamic peptide. Recently, specific receptors for CRF have been localized in the rat and monkey brain and adrenal medulla, where they are also coupled to adenylate cyclase. Brain CRF receptors are most abundant in the cerebral and cerebellar cortices and in structures related to the limbic system and control of the autonomic nervous system. The actions of CRF on the central and peripheral nervous systems, as well as on the pituitary gland, emphasize the role of CRF as a key hormone in the integrated response to stress.
