The analysis applies to objects made of zero-Gaussian curvature surfaces viewed under orthographic projection.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
An efficient use of the WATERGATE W5 sequence for observing a ligand binding with a protein receptor (2008)

An efficient pulse sequence for observing a ligand binding with a receptor has been developed by incorporating the WATERGATE W5 sequence. In the conventional water ligand observed via gradient spectroscopy (WaterLOGSY) techniques, the water resonance is selectively excited using, e.g. the double-pulsed field gradient spin-echo (DPFGSE) sequence at the initial portion of pulse sequence. In the current version, the modified WATERGATE W5 sequence is incorporated at the initial portion of the pulse sequence, and the resonance at the water frequency can be selectively reserved by the modified WATERGATE W5 sequence. The efficiency of ligand-observed NMR screening techniques has been demonstrated using the human serum albumin (HSA)-tryptophan complex.

InGaN/GaN tunnel-injection blue light-emitting diodes (2002)

A charge asymmetric resonance tunneling (CART) structure was applied to nitride-based blue light emitting diodes (LEDs) to enhance their output efficiency. It was found that with a 20-nm-thick In/sub 0.18/Ga/sub 0.82/N electron emitter layer, we could increase the LED output intensity from 28.3 minicandela (mcd) to 43.2 mcd (i.e., a 53% increase). However, a further increase in electron emitter layer thickness will reduce the intensity due to relaxation. It was also found that we could decrease the 20 mA forward voltage from 4.16 V to 3.58 V with a proper electron emitter layer.

Personalizing graphical user interfaces on flexible widget layout (2009)

The authors propose a method for personalizing the flexible widget layout (FWL) by adjusting the desirability of widgets with a pairwise comparison method, and show its implementation and that it actually works. Personalization of graphical user interfaces (GUIs) is important from a perspective of usability, and it is a challenge in the field of model-based user interface designs. The FWL is a model- and optimization-based layout framework of GUIs offering a possibility for personalization, but it has not actually realized it with any concrete method yet. In this paper, the authors implement a method for personalization as a dialog box and incorporate it into the existing system of the FWL; thus, users can personalize layouts generated by the FWL system at run-time.

Fixed drug eruptions to human immunodeficiency virus-1 protease inhibitor. (2000)

Despite numerous drug interactions that occur with human immunodeficiency virus-1 protease inhibitors, there are relatively few drug reactions. We present two patients receiving saquinavir who developed fixed drug reactions. Both reactions cleared while patients received a therapeutic dose of the medication, and in one patient a flare was seen when the patient later stopped and then restarted the medication. Although fixed drug reactions are relatively inconsequential, it is important to know that these eruptions may clear when the patient is given uninterrupted therapy of a human immunodeficiency virus-1 protease inhibitor, with only post-inflammatory hyperpigmentation.
Functional Geometry Alignment and Localization of Brain Areas. (2010)

Matching functional brain regions across individuals is a challenging task, largely due to the variability in their location and extent. It is particularly difficult, but highly relevant, for patients with pathologies such as brain tumors, which can cause substantial reorganization of functional systems. In such cases spatial registration based on anatomical data is only of limited value if the goal is to establish correspondences of functional areas among different individuals, or to localize potentially displaced active regions. Rather than rely on spatial alignment, we propose to perform registration in an alternative space whose geometry is governed by the functional interaction patterns in the brain. We first embed each brain into a functional map that reflects connectivity patterns during a fMRI experiment. The resulting functional maps are then registered, and the obtained correspondences are propagated back to the two brains. In application to a language fMRI experiment, our preliminary results suggest that the proposed method yields improved functional correspondences across subjects. This advantage is pronounced for subjects with tumors that affect the language areas and thus cause spatial reorganization of the functional regions.
Extraction of Road Intersections from GPS Traces Based on the Dominant Orientations of Roads (2017)

Many studies have used Global Navigation Satellite System (GNSS) traces to successfully extract segments of road networks because such data can be rapidly updated at a low cost. However, most studies have not focused on extracting intersections, which are indispensable parts of road networks in terms of connectivity. However, extracted intersections often present unsatisfactory precision and misleading connectivity. This study proposes a novel method for extracting road intersections from Global Position System (GPS) trace points and for capturing intersections with better accuracy. The key to improving the geometric accuracy of intersections is to identify the dominant orientations of road segments around intersections, merge similar orientations and maintain independent conflicting orientations. Extracting intersections by aligning the dominant orientations can largely reduce location offsets and road distortions. Experiments are performed to demonstrate the increased accuracy and connectivity of extracted road intersections by the proposed method.
A robust method of x-ray source spectrum estimation from transmission measurements: Demonstrated on computer simulated, scatter-free transmission data (2005)

Knowledge of the x-ray spectrum in diagnostic imaging is important for dose calculations, correction for beam-hardening artifacts, and dual-energy computed tomography. One way to determine the x-ray source spectrum is to estimate it from transmission data of a known phantom. Although such an approach is experimentally simple, spectrum estimation from transmission data is known to be an ill-conditioned problem. The contribution of this work is twofold. First, we present a systematic method of designing the transmission measurements to reduce the mathematical instability of spectrum estimation. Second, we apply the expectation-maximization (EM) method, which is known to yield robust solutions to positive, linear integral equations such as the one that describes spectrum estimation from transmission data. The proposed EM method is compared to other algorithms in the literature on simulated data from x-ray spectra typical to mammography and computed tomography. The EM method appears to outperform existing algorithms for spectrum estimation.
Detection of Mycoestrogen Zearalenone by a Molecularly Imprinted Polypyrrole-Based Surface Plasmon Resonance (SPR) Sensor (2009)

The aim of the present work was to investigate the feasibility of employing the molecular imprinting polymer technique for detecting the mycotoxin zearalenone using a surface plasmon resonance (SPR) transducer. The molecularly imprinted polypyrrole (MIPPy) film was prepared by electropolymerization of pyrrole onto the bare Au chip in the presence of a template zearalenone molecule. The MIPPy-SPR sensor exhibited a linear response in the range of 0.3−3000 ng/mL (R(2) = 0.993) for detection of zearalenone. The selectivity efficiencies of zearalenone and other structurally related analogues were 1.0 and 0.15−0.27, respectively. The limit of detection and average recovery of blank corn matrix spiked with 30 ng/g zearalenone were 0.3 ng/g and 89%, respectively, and these were found to be comparable to those obtained by enzyme-linked immunosorbent assay. These results suggest that a combination of SPR sensing with MIPPy film is a promising alternative method for the detection of zearalenone.
Production and characterization of recombinant heteropolymers of human ferritin H and L chains (1993)

Vertebrate ferritins are iron storage proteins composed by 24 subunits of one or more types. The recombinant homopolymers of human ferritin H- and L-type chains differ in iron uptake and in physical stability, but the properties of heteropolymers with various proportions of H- and L-type chains cannot be predicted. Present study shows that unfolded human ferritin H- and L- type chains renature under similar conditions to form homopolymers indistinguishable from the native ones and that, when mixed, the unfolded H and L chains renature to form heteropolymers with restricted heterogeneity and with the expected H:L ratios. Seven of these ferritins with different H:L ratios were analyzed; electrophoretic mobility, immunological reactivity, and stability to guanidine denaturation varied as predicted, based on the homopolymers. In contrast, the rate of iron uptake, monitored by the variation of absorbance at 310 nm, increased in the ferritins that ranged in H chain content from 0 to 35%; further increments in H chains had no additional effect. This finding indicates that, under the present conditions, only a limited number of H chains are needed for the maximum rate of ferritin iron uptake. Variations of L- and H-type chains in vivo may thus have biological relevance.

Taste Components of Japanese Spiny and Shovel-Nosed Lobsters (1996)

Methanol extracts were prepared from the abdominal muscles of Japanese spiny andshovel-nosed lobsters and free amino acids, ATP related compounds, betaines, and other components in the extracts were analyzed. The two lobsters were rich in glycine, arginine, glycine betaine, trimethylamine oxide, glutamine, taurine, homarine, proline, alanine, ADP, Na+, K+, PO43-, and Cl-. Glycine, arginine, proline, alanine, glutamic acid, glycine betaine, trimethylamine oxide, AMP, IMP, NaCl, KCl, and KH2PO4. They were confirmed to be taste-active for the Japanese spiny lobster taste by the sensory taste test. As for shovelnosed lobster, valine, isoleucine, leucine, sarcosine, and methionine were tasteactive in addition to theabove 11 components except IMP.
Combination of iCVD and Porous Silicon for the Development of a Controlled Drug Delivery System (2012)

We describe a pH responsive drug delivery system which was fabricated using a novel approach to functionalize biodegradeable porous silicon (pSi) by initiated chemical vapor deposition (iCVD). The assembly involved first loading a model drug (camptothecin, CPT) into the pores of the pSi matrix followed by capping the pores with a thin pH responsive copolymer film of poly(methacrylic acid-co-ethylene dimethacrylate) (p(MAA-co-EDMA)) via iCVD. Release of CPT from uncoated pSi was identical in two buffers at pH 1.8 and pH 7.4. In contrast, the linear release rate of CPT from the pSi matrix with the p(MAA-co-EDMA) coating was dependent on the pH; release of CPT was more than four times faster at pH 7.4 (13.1 nmol/(cm(2) h)) than at pH 1.8 (3.0 nmol/(cm(2) h)). The key advantage of this drug delivery approach over existing ones based on pSi is that the iCVD coating can be applied to the pSi matrix after drug loading without degradation of the drug because the process does not expose the drug to harmful solvents or high temperatures and is independent of the surface chemistry and pore size of the nanoporous matrix.

Supporting zoomable video streams with dynamic region-of-interest cropping (2010)

Streaming of an arbitrary region of interest (RoI) from a high resolution video is essential to supporting zooming and panning within a video stream. This paper explores two methods for RoI-based streaming, referring to them as tiled streaming and monolithic streaming. Tiled streaming partitions video frames into grid of tiles and encodes each tile as an independently decodable stream. Monolithic streaming applies to video encoded using off-the-shelf encoder, and relies on a pre-computed dependency information to send the necessary bits for the RoI. We evaluated these two methods in terms of bandwidth efficiency, storage requirement, and computational costs under different video encoding parameters. Experimental results show that bandwidth efficiency of tiled streams for RoI-based streaming reduces when tile size increases, despite improvement in compression efficiency. In the case of monolithic streams, use of a larger motion vector range coupled with careful run-time optimization can still improve the bandwidth efficiency, despite an increase in motion vector dependency.

The Early Ontogeny of the Columella Auris Of Crocodilus Niloticus and its Bearing on Problems Concerning the Upper end of the Reptilian Hyoid Arch (1974)

AbstractThe columella amis in Crocodilus niloticus has been found to comprise the two upper segments of the hyoid arch, viz., a forked pharyngohyal and an epihyal. To these two primary arch divisions becomes added a laterohyal component derived from delaminating subepidermal blasteme. The crocodilian stapes represents the infrapharyngohyal; the suprastapedial stem (or basal portion of the lacertilian dorsal process) represents the suprapharyngohyal while the extrastapedial represents essentially the epihyal to which laterohyal material contributes the tympanic process as well as the suprastapedial (or lacertilian intercalary). The lateral limb of the so-called lateral prong of the reptilian and avian columella auris is also a laterohyal derivative. It is concluded that in reptiles and birds: (a) the lateral limb and intercalary represent the dorsal articular head of the rhipidistian hyomandibula, (b) the proximal end of the epihyal represents its ventral articular head and (c) the so-called Huxley's foramen is the original passage between the two. Since the lacertilian internal process arises from the pharyngohyal it cannot represent the original rhipidistian quadrate-hyomandibular articulation.

Abstract Based on the daily data of temperature (T) and precipitation (P) of Heilongjiang River basin, Mann–Kendall test method, the linear least-squares regression model and hydrological statistical analysis methods were selected to analyze the variations of temperature, precipitation, and extreme events in Heilongjiang River. The results revealed that T had significant increasing trends, and annual P increased only in the lower reaches. The annual extreme low temperature (ELT) increased obviously. Both the annual extreme high temperature (EHT) had noticeable increasing trends. The outputs can provide a valuable theoretical basis for sustainable development and utilization of water resources in Heilongjiang River.

Peroxide-controlled degradation of poly(propylene): rheological behaviour and process modelling (2000)

The control of the molecular weight distribution of poly(propylene) resins by peroxide degradation is widely used in polymer industry. It allows to adjust the viscosity of these resins to the level required for processing applications. The purpose of this work was to characterise the influence of peroxide degradation on the rheological behaviour of an homopolymer PP and a block copolymer PP/PE, and to use these results to obtain a predictive model of the degradation in a twin-screw extruder. By coupling a thermomechanical model of the twin-screw extrusion process, a kinetic model of the considered reactions and the rheological behaviour, it was possible to calculate the changes in molecular weight along the extruder, during the peroxide-controlled degradation.

Axial force imparted by a conical radiofrequency magneto-plasma thruster (2012)

Direct thrust measurements of a low pressure (∼0.133 Pa) conical radiofrequency (rf at 13.56 MHz) argon plasma source show a total axial force of about 5 mN for an effective rf power of 650 W and a maximum magnetic field of 0.018 T, of which a measured value of 2.5 mN is imparted by the magnetic nozzle. A simplified model of thrust including contributions from the electron pressure and from the magnetic field pressure is developed. The magnetic nozzle is modelled as a “physical” nozzle of increasing cross-sectional area.
Remyelination in demyelinating diseases of the central nervous system. (1987)

It is well accepted that a thorough understanding of pathogenetic mechanisms involved in demyelination and remyelination of the central nervous system (CNS) is fundamental to a better understanding of the etiology and pathogenesis of clinical demyelinating disease. In this review, experimental and clinical models of demyelination are discussed in an attempt to elucidate the mechanism by which they cause breakdown of the myelin sheath and/or damage to the oligodendrocyte. An attempt is made to determine whether mechanisms operating during experimental diseases may be applicable to the human situation. In a similar fashion, the occurrence of remyelination within the CNS in experimental animals and its relationship to the potential for remyelination following not only demyelinating disease but also remyelination following trauma and other destructive lesions are explored. The evidence for meaningful remyelination in the clinical situation is assessed, and the importance of such theoretical factors as the ability of oligodendrocytes to proliferate and migrate is evaluated.
