Construction of Three-Dimensional Improved-Quality Triangulations Using Local Transformations (1995)

Three-dimensional Delaunay triangulation are the most common form of three-dimensional triangulation known, but they are not very suitable for tetrahedral finite element meshes because they tend to contain poorly shaped sliver tetrahedra. In this paper, we present an algorithm for constructing improved-quality triangulation with respect to a tetrahedron shape measure. This algorithm uses combination of two or more local transformations to improve a given triangulation toward an optimal triangulation. Experimental results on finite element meshes show that this algorithm is much more effective than previous methods at removing slivers from Delaunay triangulation and producing nearly optimal triangulation. A variation of this algorithm for improving a pseudo locally optimal non-Delaunay triangulationn toward a Delaunay triangulation is also presented.
A pneumatic artificial larynx popularized in Hong Kong (1994)

The 'Taiwan tube' is an inexpensive pneumatic artificial larynx made in Taiwan. The device, which is a tracheo-oral shunt containing a resonator, is popular with laryngectomees in Hong Kong. This paper reports its use and describes its working dynamics which compare favourably with those of other forms of voice restoration.
Bitter gourd (<i>Momordica charantia</i>) improves insulin sensitivity by increasing skeletal muscle insulin-stimulated IRS-1 tyrosine phosphorylation in high-fat-fed rats (2007)

The aim of this present study was to investigate the effect of bitter gourd extract on insulin sensitivity and proximal insulin signalling pathways in high-fat-fed rats. High-fat feeding of male Wistar rats for 10 weeks decreased the glucose tolerance and insulin sensitivity compared to chow-fed control rats. Bitter gourd extract supplementation for 2 weeks (9th and 10th) of high-fat feeding improved the glucose tolerance and insulin sensitivity. In addition bitter gourd extract reduced the fasting insulin (43 (se 4.4) v. 23 (se 5.2) microU/ml, P < 0.05), TAG (134 (se 12) v. 96 (se 5.5) mg/dl, P < 0.05), cholesterol (97 (se 6.3) v. 72 (se 5.2) mg/dl, P < 0.05) and epidydimal fat (4.8 (se 0.29) v. 3.6 (se 0.24) g, P < 0.05), which were increased by high-fat diet (HFD). High-fat feeding and bitter gourd supplementation did not have any effect on skeletal muscle insulin receptor, insulin receptor subtrate-1 (IRS-1) and insulin- stimulated insulin receptor tyrosine phosphorylation compared to chow-fed control rats. However high-fat feeding for 10 weeks reduced the insulin-stimulated IRS-1 tyrosine phosphorylation compared to control rats. Bitter gourd supplementation together with HFD for 2 weeks improved the insulin-stimulated IRS-1 tyrosine phosphorylation compared to rats fed with HFD alone. Our results show that bitter gourd extract improves insulin sensitivity, glucose tolerance and insulin signalling in HFD-induced insulin resistance. Identification of potential mechanism(s) by which bitter gourd improves insulin sensitivity and insulin signalling in high-fat-fed rats may open new therapeutic targets for the treatment of obesity/dyslipidemia-induced insulin resistance.

Cost-effective masks for deep x-ray lithography (2003)

The production of X-ray masks is one of the key techniques for X-ray lithography and the LIGA process. Different ways for the fabrication of X-ray masks has been established. Very sophisticated, difficult and expensive procedures are required to produce high precision and high quality X-ray masks. In order to minimize the cost of an X-ray mask, the mask blank must be inexpensive and readily available. The steps involved in the fabrication process must also be minimal. In the past, thin membranes made of titanium, silicon carbide, silicon nitride (2-5μm) or thick beryllium substrates (500μm) have been used as mask blanks. Thin titanium and silicon compounds have very high transparency for X-rays; therefore, these materials are predestined for use as mask membrane material. However, the handling and fabrication of thin membranes is very difficult, thus expensive. Beryllium is highly transparent to X-rays, but the processing and use of beryllium is risky due to potential toxicity. During the past few years graphite based X-ray masks have been in use at various research centers, but the sidewall quality of the generated resist patterns is in the range of 200-300 nm Ra. We used polished graphite to improve the sidewall roughness, but polished graphite causes other problems in the fabrication of X-ray masks. This paper describes the advantages associated with the use of polished graphite as mask blank as well as the fabrication process for this low cost X-ray mask. Alternative membrane materials will also be discussed.
Interactive Higher-Order Network Analysis (2018)

Higher-order network modeling and analysis is vital to understand the structures governing the configuration and behavior of complex networks. While network motifs are known to be fundamental building blocks of complex networks, the higher-order configuration and organization of complex networks remains widely unknown. In this work, we develop interactive visual higher-order network mining and modeling techniques to gain insight into the higher-order structure and composition of complex networks. The approach uncovers higher-order configurations including important phenotypes in a human gene interaction network and hubs in a power grid network.
Hydrogen Bonding of Methanol in Supercritical CO<sub>2</sub> Studied by <sup>13</sup>C Nuclear Spin−Lattice Relaxation (1997)

A sapphire high-pressure NMR cell, capable of independently controlling sample pressure, temperature, and concentration, is used to measure 13C spin−lattice relaxation times for dilute methanol in dense carbon dioxide at pressures from 80 to 220 atm and temperatures from 287 to 334 K. These ranges of temperature and pressure provide relaxation data for methanol in both the liquid and supercritical fluid phases of CO2. The nuclear Overhauser effect (NOE), used for separating the contributions of the dipolar and spin-rotation mechanisms, has also been measured. Spin-rotation relaxation theory, together with proposed hydrogen-bonding models, is used to interpret the experimental data. The partial molar enthalpy changes for hydrogen bond formation agree well with those reported by Smith et al. using FTIR (J. Am. Chem. Soc. 1991, 113, 8327−8334) and commonly accepted hydrogen bond energies. A large negative change in the partial molar volume arising from hydrogen bond formation in methanol is observed near the critical temperature of the CO2−methanol mixture.
Optical thin films of silica and titania deposited by plasma polymerisation process : System design and fabrication (2008)

Plasma polymerization provides a very versatile and cost-effective technique for the deposition of a wide variety of\ndielectric films, in particular optical thin films of silica (silicon dioxide) and titania (titanium dioxide) that are widely used\nas low and high index films in optical multilayer coatings for a variety of applications. The deposition of these films is often\ncarried out using toxic and corrosive precursors–silane gas for silica and titanium tetrachloride liquid for titania – that are\nexpensive and difficult to handle. The use of non-toxic organic liquid precursors, that are cheaper and safer and easier to\nhandle, has been reported for the deposition of these films. In order to develop indigenous expertise in such deposition\nprocesses, a plasma polymerization deposition system that uses non-toxic and safe organic liquid precursors for the\ndeposition of optical quality silica and titania films has been designed and fabricated in-house and successfully made\noperational. The problems that arise in this deposition process, the methods adopted to overcome them, the precautions that\nmust be taken, have been studied in detail. Optical quality silica and titania films with satisfactory refractive indices and\nextinction coefficients have been deposited using this home-made deposition system.

Evaluating New Technology to Improve Patient Outcomes (2002)

The nurses in the peripherally inserted central catheter (PICC) program at the University of Washington Medical Center perform ongoing data tracking to measure team and patient outcomes. Quality improvement initiatives have included the transition to microintroducer technology and ultrasound-guided placement. Used together, this technology has allowed the PICC team to increase their bedside insertion success rate to 91%. The group has also changed PICC securement methods, and use of the Statlock anchoring device has reduced the incidence of catheter migration from 6% to 1.5% of all catheter lines placed. Catheter durability also was assessed. The Pressure Activated Safety Valve PICC was compared to the Groshong PICC and the rate of catheter repair and exchange due to breakage has been reduced from 11% to 1%.
Oligodendrocytes in the early course of multiple sclerosis (1994)

The neuropathology of demyelinating lesions in multiple sclerosis was studied in specimens obtained by diagnostic needle biopsy during early stages of the disease. The lesions were characterized by a chronic inflammatory reaction dominated by lymphocytes and macrophages, plaque-like demyelination, and astroglial sclerosis. Oligodendrocytes within the lesions were studied by immunocytochemistry using antibodies against various myelin and oligodendroglia components. The expression of messenger RNA for proteolipid protein was determined by in situ hybridization. Our studies revealed that myelin-oligodendrocyte glycoprotein is a sensitive and reliable marker for identification of oligodendrocytes in demyelinated plaques. The results suggest that in the early course of the disease in some patients, oligodendrocytes may largely be preserved, whereas in others oligodendroglial loss is pronounced. Loss of oligodendrocytes was only marginally related to the stage of demyelinating activity within the lesions. These findings indicate that the pathogenesis of demyelination may vary within different multiple sclerosis patients.
Electronic Configuration in Electrodeposition from Aqueous Solutions (1954)

Consideration of electronic structures of metal ions in aqueous solutions indicates that metals are electrodeposited from ions in which coordinate linkages involve only orbitals of the outermost electronic shell. When coordination involves the penultimate shell also, that is, with Taube's "inner orbital" complexes, the metal is not electrodeposited. Apparently the energy required to break such hybridization exceeds that required for cathodic discharge of hydrogen from these solutions. Platinum metals are exceptions, probably because of extraordinary stability of the metallic state for these elements; deposition, however, requires high activation, as shown by over‐ potentials and low current efficiencies. Between different oxidation states, electrolytic oxidation or reduction is irreversible if the electronic configuration must be changed significantly. Irreversible deposition is observed for transition metals or when the ion is bound in a hydrolyzed aggregate. Since inner orbital hybridization is associated with a lack of substitutional lability of the coordinated groups, whereas lability of outer orbital complexes probably results from formation of a dissociation interm iate, it is likely that such an intermediate is also important in the cathode process. These considerations are used to account for and extend the Piontelli electrolytic classification of metals. In considering the effects of anions, it is shown that aquo complexes are reduced with highest irreversibility, which is attributed to high activity of water; the influence of halide ions may be labilization by the trans effect.
New antipsychotic agents for schizophrenia: pharmacokinetics and metabolism update. (2002)

The so-called atypical antipsychotics undergo extensive metabolism, except for amisulpride, which is substantially excreted unchanged. Risperidone is oxidized by CYP2D6/CYP3A4 and iloperidone is reduced by cytosolic enzymes, although CYP1A2, CYP2E1 and CYP3A4 are involved as well. Olanzapine is both conjugated and oxidized (mainly by CYP1A2), while quetiapine and zotepine primarily undergo CYP3A4-mediated oxidation. Ziprasidone pathways include aldehyde oxidase-mediated reduction and CYP3A4-mediated oxidation. The main metabolites of risperidone, zotepine and possibly perospirone and ziprasidone contribute to the parent drug's effect. Information is limited, however, on some promising antipsychotics in the pipeline.
Information understanding: integrating data fusion and data mining processes (2002)

Data fusion and data mining are complementary processes that contribute abductive-inductive (learning and discovery) and deductive (detection) capabilities. Not to be confused with each other, the processes offer distinct and reciprocal capabilities that, once integrated, provide powerful tools for improving the automatic recognition of targets by complex, nonliteral signatures from multiple sources. ERIM International is developing and applying this integrated technology to improve the performance of traditional data fusion processes.
Novel Heat Resistant Plastics from Hydrogenation of Styrene Polymers (1973)

The combination of polymer preparation by anionic techniques and hydrogenation technology based on soluble transition metal catalysts has allowed the facile hydrogenation of polystyrene and styrene—diene block copolymers. Problems encountered in hydrogenation of polymers using conventional techniques have been avoided. Polystyrene is hydrogenated to poly(vinylcyclohexane) (PVCH) which has a heat distortion temperature 60°C higher than polystyrene. PVCH, however, has low impact strength. By hydrogenating styrene—diene block copolymers, materials with heat and impact resistance resulted. By varying the level of polystyrene in the diene block copolymers products of hydrogenation ranged from rubbery to rigid materials all of which were clear, tough, and heat resistant.
Correlative Filters for Convolutional Neural Networks (2015)

This paper introduces a regularization method called Correlative Filter (CF) for Convolutional Neural Network (CNN), which takes advantage of the relevance between the convolutional kernels belonging to the same convolutional layer. During the process of training with the proposed CF method, several pairs of filters are designed in a manner of randomness to contain opposite weights in low-level layers. Regarding higher level layers where synthetical features are processed, the relation between correlative filters is explored as translation of various directions. The proposed CF method attempts to optimize the inner structure of convolutional layers and it can work jointly with other regularization techniques, such as stochastic pooling, Dropout, etc. The experimental results on the competitive image classification benchmark dataset CIFAR-10 demonstrates the performance of the proposed CF method, additionally, it is also verified that the proposed CF method is wonderful to be employed to enhance several state-of-the-art regularization models.
Unconventional electrical machine for circulating molten metal (1978)

The paper deals with the application of an unconventional electrical machine for circulating molten aluminium in reverberatory furnaces. Its design is based on the classical jumping-ring principle, and it incorporates some hitherto less known aspects of open magnetic circuits and of the concepts of flux spreading. Results of trials using a prototype machine are given, and the metallurgical and other benefits which accrue from its use are discussed. To maintain the electromagnetic integrity of this machine at liquid-metal temperature (> 700°C), a study of its thermal behaviour is made using a mathematical model. This model is subsequently verified by experimental observations. Proposals are made for the future use of some unconventional electrical machines in an aluminium remelt plant.
Influence of Temperature on the Radiation Response of Mammalian Cells in Tissue Culture (1963)

Mammalian cells in tissue culture were irradiated at 5 un. Concent 85% C, 37 un. Concent 85% C, or 40 un. Concent 85% C. Cells irradiated at 5 un. Concent 85% C demonstrate radioresistance compared to cells irradiated at 40 un. Concent 85% C by a factor of 1.59. It is suggested that low temperature results in protection rather than enhances recovery. The nature of this protection is not known but it is thought to be associated closely with slowed rate processes and recombination of molecules in the metionic state before deieterious reactions can take place.

The integrated operating room system - a pathway to the or 2000 and beyond. (1998)

The need to create a new kind of operating room (OR) is obvious from the situation today. Although a number of innovative and even futuristic OR concepts have been proposed, the challenge to implement the OR of the future has never been met. In the Integrated OR System project we came to the conclusion that we have to proceed to new values and new approaches to make the OR of the next millennium happen. By following those new roads we will not only overcome the deficiencies of the OR today but also create a platform that allows easy inclusion of upcoming technology.
Lanthanum-Doped Hafnium Oxide: A Robust Ferroelectric Material (2018)

Recently simulation groups have reported the lanthanide series elements as the dopants that have the strongest effect on the stabilization of the ferroelectric non-centrosymmetric orthorhombic phase in hafnium oxide. This finding confirms experimental results for lanthanum and gadolinium showing the highest remanent polarization values of all hafnia-based ferroelectric films until now. However, no comprehensive overview that links structural properties to the electrical performance of the films in detail is available for lanthanide-doped hafnia. La:HfO<sub>2</sub> appears to be a material with a broad window of process parameters, and accordingly, by optimization of the La content in the layer, it is possible to improve the performance of the material significantly. Variations of the La concentration leads to changes in the crystallographic structure in the bulk of the films and at the interfaces to the electrode materials, which impacts the spontaneous polarization, internal bias fields, and with this the field cycling behavior of the capacitor structure. Characterization results are compared to other dopants like Si, Al, and Gd to validate the advantages of the material in applications such as semiconductor memory devices.
Sonochemically-Assisted Modification of Polyethylene Surfaces (1996)

The oxidation of polyethylene surfaces with a range of mild oxidizing agents enhanced by the use of ultrasound is described. The use of sonochemical methods allows significant levels of surface modification to be achieved using oxidizing agents such as hydrogen peroxide and persulfate salts around ambient temperatures under mild conditions. Changes in the water contact angle and attenuated total reflection IR spectroscopy were used to follow the changes in surface chemistry. Variation of the experimental conditions such as treatment time and sound intensity allowed control over the extent and nature of the surface oxidation. Although the changes achieved with laboratory equipment are relatively slow, more significant effects could be obtained at higher ultrasound intensities.
드라이버 밸런스의 변화가 정확성에 미치는 운동학적 연구 (2009)

The purpose of the study was to examine what phenomenon took place after swing with three kinds of drivers manufactured specially to examine an effect of change of head weight in swing on quality of pitch. For test, the study manufactured clubs with different balances-DO, D2.5 and D5- and analyzed quality of pitch with trackman. When pro golfers hit balls in about 107mile head speed, the study investigated their accuracy and direction. As the results, a club with D2.5 in head weight was the best accuracy and direction. In the light head D0, the study could see that swing orbit moved toward outside/in, had a high trajectory and consequently had a lot of hooks. A club with heavy head of D5 had the same result as D2.5 club in the side of efficiency. However, in all factors of overall driving distance and direction, it was not beyond D2.5. Averagely as much as head is light, there were diverse deviations such as hook, slice, fade and throw after impacting. The deviation was reduced as much as head was heavy. Examining D2.5 club with the best result, it had fade moving to the right side in the landing point although face was somewhat closed in the impact point. In flight time, fade had less time than hook. However, in direction and driving distance, it had a little deviation and the best direction and driving distance.
Research on control method of T-type three-level topology (2016)

A T-type three-level inverter topology is studied in this paper, and a control method based on the topology is presented. For T-type topology, according to the polarity of the load current, the method take a correspondingly control to the switch state of zero level to output the reference voltage, which reduce the switch loss. To solve the problem of neutral-point potential balance, neutral-point charge adjustment algorithm is introduced, which effectively suppress neutral point voltage drift. Finally, T-type three-level model is built under environment of MATLAB and the results of simulation verify the feasibility and effectiveness of the control method.
