Dynamics of inviscid capillary breakup: collapse and pinchoff of a film bridge (1997)

An axisymmetric film bridge collapses under its own surface tension, disconnecting at a pair of pinchoff points that straddle a satellite bubble. The free-boundary problem for the motion of the film surface and adjacent inviscid fluid has a finite-time blowup (pinchoff). This problem is solved numerically using the vortex method in a boundary-integral formulation for the dipole strength distribution on the surface. Simulation is in good agreement with available experiments. Simulation of the trajectory up to pinchoff is carried out. The self-similar behaviour observed near pinchoff shows a ‘conical-wedge’ geometry whereby both principal curvatures of the surface are simultaneously singular – lengths scale with time as t 2/3 . The similarity equations are written down and key solution characteristics are reported. Prior to pinchoff, the following regimes are found. Near onset of the instability, the surface evolution follows a direction dictated by the associated static minimal surface problem. Later, the motion of the mid-circumference follows a t 2/3 scaling. After this scaling ‘breaks’, a one-dimensional model is adequate and explains the second scaling regime. Closer to pinchoff, strong axial motions and a folding surface render the one-dimensional approximation invalid. The evolution ultimately recovers a t 2/3 scaling and reveals its self-similar structure.
An interactive and team approach to multimedia design curriculum (2005)

Over the past decade, increasingly powerful technologies have made it easier to compress, distribute, and store multimedia content. The merger of computing and communications has created a ubiquitous infrastructure that brings digital multimedia closer to the users and opens up tremendous educational and commercial opportunities in multimedia content creation, delivery, rendering, and archiving for millions of users worldwide. Multimedia has become a basic skill demanded by an increasing number of potential jobs for electrical engineering/computer science graduates. In this article, the authors intend to share their experiences and new ways of thinking about curriculum development. It is beneficial for colleagues in the multimedia signal processing areas for use in developing or revising the curriculum to fit the needs and resources of their own programs.
Crustacean hemocyanin gene family and microarray studies of expression change during eco-physiological stress (2006)

Proteins in the arthropod hemocyanin gene family are involved in major physiological processes, including aerobic respiration, the innate immune response, and molting. Members of this family, hemocyanin, cryptocyanin, and phenoloxidase, are multisubunit molecules that assemble into hexamers and higher aggregates. The hemocyanin hexamers show species-specific subunit heterogeneity. It is hypothesized that this subunit diversity is maintained as a mechanism of selection for functional diversity under changing developmental and environmental conditions. There is good evidence for a strong relationship between subunit composition and functional diversity in the hemocyanins. We have amplified, cloned, and sequenced the complete cDNAs of the 6 hemocyanin genes, 2 cryptocyanins, and 1 phenoloxidase of Cancer magister. Alignment of the amino acid sequences provides the first opportunity to assess in 1 species of brachyuran crustacean the similarities and differences among all the hemocyanin subunits and compare them with cryptocyanin and phenoloxidase. A phylogeny of sequences of crustacean members of the arthropod hemocyanin gene family is described. Construction of a cDNA library for C. magister microarray studies is in progress. The microarrays will be queried using transcriptional profiles from crabs sampled during developmental, molting, and physiological perturbations. The combination of genomics, proteomics, and gene-by-gene analyses will help us dissect how much a gene sequence in this hemocyanin family can vary while conserving function and which aspects of preservation of shape and structural flexibility are essential for functional stability. Integrating focused gene studies with global-expression profiling can eventually lead to the identification of functional networks at the level of the gene, the multisubunit molecule, and the whole organism.
<i>Lodderomyces elongisporus</i> Masquerading as <i>Candida parapsilosis</i> as a Cause of Bloodstream Infections (2007)

Ten yeast bloodstream isolates identified as Candida parapsilosis by conventional methods grew as turquoise blue colonies on Chromagar media. Subsequent sequence analysis showed that these isolates were the species Lodderomyces elongisporus. To our knowledge, this is the first published report of L. elongisporus as a cause of human disease.
MobileFusion: Real-Time Volumetric Surface Reconstruction and Dense Tracking on Mobile Phones (2015)

We present the first pipeline for real-time volumetric surface reconstruction and dense 6DoF camera tracking running purely on standard, off-the-shelf mobile phones. Using only the embedded RGB camera, our system allows users to scan objects of varying shape, size, and appearance in seconds, with real-time feedback during the capture process. Unlike existing state of the art methods, which produce only point-based 3D models on the phone, or require cloud-based processing, our hybrid GPU/CPU pipeline is unique in that it creates a connected 3D surface model directly on the device at 25Hz. In each frame, we perform dense 6DoF tracking, which continuously registers the RGB input to the incrementally built 3D model, minimizing a noise aware photoconsistency error metric. This is followed by efficient key-frame selection, and dense per-frame stereo matching. These depth maps are fused volumetrically using a method akin to KinectFusion, producing compelling surface models. For each frame, the implicit surface is extracted for live user feedback and pose estimation. We demonstrate scans of a variety of objects, and compare to a Kinect-based baseline, showing on average ∼ 1.5cm error. We qualitatively compare to a state of the art point-based mobile phone method, demonstrating an order of magnitude faster scanning times, and fully connected surface models.
半側空間無視を有する患者における“自発的解決を促す介入"の効果の検討 (2003)

半側空間無視は右半球脳損傷による後遺症として比較的頻繁に現れ,患者の日常生活への復帰を困難にする因子として知られる.本研究はこれに対するアプローチにおいて患者の自発性という問題に焦点をあて,これを促すことが半側空間無視の改善を生むかどうかを検証することをめざしたものである.なお,本研究において“自発的解決を促す介入"とは患者が興味のある課題を行う中で,無視症状の正しい認識と代償戦略の立案・獲得を促すことを目的にデザインされたものである.2症例を対象にそれぞれA-B-A'型のシングルケースデザインを用いて実験を行った.独立変数を“自発的解決を促す介入"の有無,従属変数を半側空間無視による見落とし数を標的とした半側空間無視量とし,A,B,A'各期それぞれ10回のセッションを週3～4回の頻度で実施した.さらに汎化の程度を調べる目的で,行動性無視検査を実験開始時と各期の終了時に計4回実施した.その結果,半側空間無視量は2症例ともB期において改善を示し,行動性無視検査の成績も1症例においてB期終了後に改善を示した.また,B期で得られた代償法のA'期における使用や自発的な無視に関するコメントの出現が認められた.すなわち,“自発的解決を促す介入"は半側空間無視に対する病識の芽生えと代償法の獲得ならびに拡張的使用を促すものと判断された.
Polyethers containing coumarin dimer components in the main chain. II. Reversible photocleavage and photopolymerization (1997)

Polyethers, containing coumarin dimer components in the main chain, were irradiated successively in 1,4-dioxane with 254 and 350 nm (or 300 nm) light to investigate their reversible photoreaction properties. The coumarin dimer components cleave symmetrically under 254 nm (photocleavage) to original dioxycoumarins. Irradiating the cleaved sample with 350 nm (or 300 nm) leads to polymerization of the dioxycoumarins via dimerization of the telechelic coumarin chromophores (λmax = 320 nm). The absorbances at 320 nm of the sample solution were used to trace the photoreactions. For both 5 and 6, the maximum absorbance (ABS) and ΔABS increase with the number of cycles (one photocleavage followed with one photopolymerization). However, the degenerates (percent decrease of absorbance per cycle) of 5 (ca. 50%) are much greater than those of 6 with 4-methyl substitution (ca. 29%), which has been explained by the formation of coumarin dimer components which are difficult to cleave under 254 nm. Moreover, photocleavage (254 nm) is much faster than is photopolymerization (350 nm) for both 5 and 6 due to the high-energy intensity of 254 nm light. Addition of the photosensitizer, benzophenone, enhances the photopolymerization rate with the photocleavage rate remaining almost unchanged. 4-Methyl substitution in 6 results in an increased rate for both reactions which can be attributable to its electron-releasing property. Photopolymerization under 300 nm light is more effective than under 350 nm, suggesting that the absorbing efficiency under 300 nm should be greater since it overlaps with the absorption of coumarin chromophores (320 nm). © 1997 John Wiley & Sons, Inc.

Preparation of Graft Copolymers By Means of Uv Photolysis of Poly(Methyl Vinyl Ketone) and Reverse Osmosis Performance of the Membranes from the Oximes of the Copolymers (1990)

ABSTRACT ABSTRACT An attempt was made to prepare a graft copolymer consisting of poly(methyl vinyl ketone) (PMVK) as a backbone chain and polyacrylonitrile, poly(4-vinylpyridine), or polystyrene as a graft chain by UV irradiation of a solution of PMKV in the presence of acrylonitrile, 4-vinylpyridine, or styrene. the influence of reaction conditions on the yield, composition, and viscosity of the resulting graft copolymers was investigated. It was suggested from NMR and gel permeation chromatography that those graft copolymers contained a high molecular weight fraction of narrow distribution and block copolymers as well. the reverse osmosis membranes derived from the oxime and amidoxime of the graft copolymers showed a characteristic performance of exhibiting a maximal difference between rejections against NaCl and CoCl2 at a certain addition ratio of crosslinking agent, which was not observed in the membranes from copolymers by conventional radical copolymerization. the relationship between these phenomena and the branching structure of the graft copolymers was discussed.

Distributed signal detection under the Neyman-Pearson criterion (2001)

A procedure for finding the Neyman-Pearson optimum distributed sensor detectors for cases with statistically dependent observations is described. This is the first valid procedure we have seen for this case. This procedure is based on a theorem proven in this paper. These results clarify and correct a number of possibly misleading discussions in the existing literature. Cases with networks of sensors in fairly general configurations are considered along with cases where the sensor detectors make multiple bit sensor decisions.
Robbins, Lionel Charles (1898–1984) (2008)

Lionel Robbins, who in 1961 became Baron Robbins of Clare Market, was one of the major academic economists of the interwar period. He remained active after the Second World War but never really regained the centre of the stage that he had occupied. He was also a great public servant for his country, serving it well and loyally in many aspects of social, political and cultural life. He was truly a ‘Renaissance man’.
An oscillator design using low g-sensitivity, low phase noise STW devices (2002)

Focuses upon results of integrating surface transverse wave (STW) technology into an oscillator product line. Phase noise of <-100 dBc/Hz at 100 Hz, noise floor of <-180 dBc/Hz, and g-sensitivity of <5/spl times/10/sup -10/ per g have been achieved at 1 GHz using STW technology. Select units have exhibited g-sensitivities below 1/spl times/10/sup -10/ per g. These 1/f and g-sensitivity results represent state of the art for 1 GHz STW oscillators. The above low phase noise and low g-sensitivity (<5/spl times/10/sup -10/ per g) have been achieved in a 1.5"/spl times/1"/spl times/.2" package. In addition, this g-sensitivity performance is attained in an industry-standard, 14-pin dual in-line package (DIP) measuring 87"/spl times/.5"/spl times/.24". Bare hybrid oscillator products with hermetically-sealed resonators have been developed at a size of .715"/spl times/.380"/spl times/.110" for subsequent hermetic module integration. Design techniques have resulted in production of standard oscillators From 300 MHz to nearly 1200 MHz and over temperature ranges from -55 degrees Celsius to +110 degrees Celsius using the exact same hybrid substrate design. The design of this hybrid circuit is discussed.
Impedance properties of complementary multiterminal planar structures (1959)

Booker has shown that Babinet's principle, properly extended to electromagnetic fields, leads to a simple relation between the impedances of two planar complementary structures. A relation, which generalizes this result, is found between the impedance matrices of two complementary <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</tex> -terminal structures. This relation is applied to the particular <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</tex> -terminal structures having <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</tex> -fold symmetry and to those that are also self-complementary. In the latter case the impedance matrix is real and entirely determined by the number of terminals. It is therefore independent of the exact shape of the elements composing the structure and of the frequency. By connecting in groups the terminals of such a structure various impedance levels, all frequency independent and real, may be achieved. Structures having their terminal pairs in different locations in the plane are also considered. A self-complementary two-port structure is found to be equivalent, from the impedance point of view, to a length of lossy transmission line having a characteristic impedance of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">60\pi</tex> ohms.
A general framework for fracture intersection analysis: algorithms and practical applications (2011)

The modelling and simulation of fracture networks is a critical component of the assessment of hot dry rock (HDR) geothermal resources and of the design and creation of enhanced geothermal systems (EGS). The production of geothermal energy from an EGS depends on fluid pathways through the HDR and thus connectivity of fractures is essential. One way of assessing and modelling fracture connectivity is by intersection analysis. There is a notable lack of research in this area reported in the published literature probably because of the extreme complexity of three-dimensional fractures in HDR especially with respect to their geometrical characteristics i.e., shapes and orientations and spatial interrelationships in the fracture network.
Chemical synthesis of biodegradable aliphatic polyesters and polycarbonates catalyzed by novel versatile aluminum metal complexes bearing salen ligands (2004)

Abstract Two novel aluminum metal complexes ( 2 and 3 ) bearing salen ligands were in situ prepared from trimethyl aluminum (AlMe 3 ), methanol, and ( R,R )‐ N,N ′‐bis(salicylidene)‐1,2‐diaminocyclohexane with original synthetic strategies, and a preliminarily resoluted ( R,R )‐1,2‐diaminocyclohexane was applied as a synthetic precursor. By means of Fourier transform infrared spectrometry, NMR spectrometry, mass spectrometry, and single‐crystal X‐ray diffractometry, 2 and 3 were revealed to be distinct molecular structures with corresponding yields of 85 and 10%, respectively. Further studies via 27 Al NMR techniques and single‐crystal X‐ray diffraction indicated that dimeric metal complex 3 appeared in the six‐coordinated state, whereas there was a dynamic equilibrium transition between the five‐ and six‐coordinated states for metal complex 2 in a CDCl 3 solution. The more stable dimeric metal complex ( 3 ) exhibited two inequivalent aluminum metal centers coordinated to nitrogen atoms attributed to two different salen ligands, and this was different from the reported salen aluminum complex structures. Furthermore, 2 and 3 were employed as candidate catalysts for the ring‐opening polymerization (ROP) of some important biodegradable aliphatic polyesters and polycarbonates, including poly(ϵ‐caprolactone) (PCL), poly(δ‐valerolactone), poly(trimethylene carbonate), and poly(2,2‐dimethyl trimethylene carbonate). The synthetic results indicated that both metal complexes efficiently catalyzed ROP at 100 °C in an anisole solution, and 3 showed much better controlled characteristics of ROP than 2 . Very narrow molecular weight distributions close to 1.21 for PCL were detected with 3 as the ROP catalyst. In addition, a catalytic mechanism study confirmed that ROP catalyzed by these metal complexes was in good agreement with the commonly accepted coordination polymerization reported for aluminum triiso [Al(O i Pr) 3 ] and stannous octanoate [Sn(Oct) 2 ]. © 2004 Wiley Periodicals, Inc.

An Inclusive Structural Analysis on the Design of 1.2kV 4H-SiC Planar MOSFETs (2021)

A detailed structural analysis of 1.2 kV 4H-SiC MOSFETs with accumulation mode channel is reported in this paper. 1.2 kV SiC MOSFETs with a variety of cell designs were fabricated and compared with respect to the output and transfer characteristics, and blocking behaviors. All the design rules, such as channel length, JFET width, contact openings, gate-to-source overlap, and cell pitch were investigated to clearly provide the quantitative impact on the static performances. 2D-simulation was also conducted to support experimental results. As a result, it turned out that the channel length is the most determining factor for the specific on-resistance, resulting in 0.364 mΩ-cm2 increase per 0.1 μm increase in the channel length. However, the channel potential is also largely dependent on the channel length such that the leakage current tends to increase with short channel design. The enhanced doping in the JFET region with a current spreading layer (CSL) is essential for achieving a narrower JFET width, which satisfies all static performances, as well as device reliability and ruggedness. Methods to further improve the trade-off characteristics using other design aspects are discussed in this paper.
Chemical and Functional Properties of Blood Globin Prepared by a New Method (1984)

ABSTRACT Globin prepared from pig blood cell concentrate by a new method based on heme precipitation with dilute carboxymethylcellulose (CMC)‐solution at acid pH showed very good water‐binding capacity compared with soy protein, lactalbumin and glutein. Water‐holding ability of globin decreased with increasing pH, drastically at pH‐value over 6.0, and with increasing ionic strength. Preheating at different temperatures decreased water‐binding capacity only slightly. A great increase in viscosity of 5% globin solution occurred between pH 5.2 and 5.8 at 95°C and a firm gel formed. Freeze‐dried gels had excellent water‐binding capacities compared with unheated samples or samples heated at other pH values. Isoelectric focusing studies showed three or four bands below Ip 7.4 for globins prepared by CMC‐precipitation method or cold acetone method and one intensive band near 7.8 for heat‐denatured globins.
Use of Positron Annihilation Spectroscopy for Stress-Strain Measurements: Quarterly Progress Report (June 01 – August 31, 2003) (2002)

Highlights of Test Results:\n• Residual stress measurements by the RC method on cold-worked specimens showed tensile residual stresses in austenitic stainless steel. However, compressive residual stresses were observed in martensitic stainless steel. This difference may be attributed to the difference in metallurgical phases and microstructures resulting from different thermal treatments imparted to them.\n• Residual stress measurements by both ND and RC techniques on welded specimens showed similar patterns. Welded specimens consisting of similar material showed tensile residual stresses in the vicinity of the fusion line (FL). However, welded specimens consisting of dissimilar materials (austenitic and martensitic stainless steel on opposite side) showed a different pattern, in that residual stresses were compressive near the FL on the martensitic stainless steel side as opposed to tensile residual stresses on austenitic stainless steel side of the same specimen.\n• The measurements of residual stresses by the PAS technique revealed a reduction in Tparameter with the increased plastic deformation for both austenitic and martensitic stainless steels. A reduced T-parameter indicates enhanced residual stresses in either Alloy.\nOther Accomplishments:\n• One graduate student performed PAS measurements on welded specimens consisting of both similar and dissimilar materials at Idaho State University (ISU) during the summer of 2004. Also, tensile test specimens were subjected to the activation process using ISU accelerator to develop calibration curves. Data analyses are ongoing.\n• Several papers, based on recent data, were presented in technical society meetings. Some of these papers are currently under review for publication in technical journals.\n• Significant progress has been made to characterize residual stresses in terms of dislocation density by using TEM.
A level-set approach to image blending (2000)

This paper presents a novel method for blending images. Image blending refers to the process of creating a set of discrete samples of a continuous, one-parameter family of images that connects a pair of input images. Image blending has uses in a variety of computer graphics and image processing applications. In particular, it ran be used for image morphing, which is a method for creating video streams that depict transformations of objects in scenes based solely on pairs of images and sets of user-defined fiducial points. Image blending also has applications for video compression and image-based rendering. The proposed method for image blending relies on the progressive minimization of a difference metric which compares the level sets between two images. This strategy results in an image blend which is the solution of a pair of coupled, nonlinear, first-order partial differential equations that model multidimensional level-set propagations. When compared to interpolation this method produces more natural appearances of motion because it manipulates the shapes of image contours rather than simply interpolating intensity values. This strategy results in a process that has the qualitative property of deforming greyscale objects in images rather than producing a simple fade from one object to another. This paper presents the mathematics that underlie this new method, a numerical implementation, and results on real images that demonstrate its effectiveness.
