Sketch-Based Controllers for Blendshape Facial Animation (2015)

The blendshape approach is a widely used technique to generate realistic facial animation. However, creating blendshape facial animations using traditional weight editing tools requires either memorizing the function of a large number of parameters, or a trial-and-error search in a high-dimensional space. Direct manipulation interfaces address this problem, allowing the artist to directly move and pin manipulators placed on the surface of the face. Placing manipulators is an open-ended and slightly unnatural task for artists however. In this paper we present a sketch-based approach to this problem, inspired by artists' brush painting on canvas. In this approach the artist simply sketches directly onto the 3D model the positions of the manipulators that they feel are needed to produce particular facial expression. The manipulators activate the blendshapes in the model and allow the user to interactively create the desired facial poses by a dragging operation in screen coordinates. Our hybrid method can be used with any blendshape facial model and allows producing expeditious manipulation in an intuitive way.
Thermal Degradation of Nitride Phosphors (2015)

Thermal stability of phosphors for solid state lighting is usually investigated by in-situ measuring the thermal quenching behavior of the sample heated up to ~ 300 o C and held at each temperature for a certain time. However, thermal quenching does not have the same meaning with thermal degradation, which thus cannot evaluate the stability of the phosphor against thermal attacks comprehensively. In this work, we attempted to study the thermal degradation of nitride phosphors (i.e., SrSi 2 O 2 N 2 :Eu and CaAlSiN 3 :Eu) by baking the powders in air or in pressued water steam at high temperatures. The degradation mechanism was discussed and clarified by carrying out the surface state analysis using various techniques. For SrSi 2 O 2 N 2 :Eu, the PL intensity decreased as the baking temperature rises, degrading by 10 and 30% when the samples baked at 500 and 600 o C, respectively. In comparison with Ca-α-sialon:Eu 2+ that retained its luminescence up to 800 o C, SrSi 2 O 2 N 2 :Eu showed a very serious thermal degradation. By conducting the high-temperature in-situ XRD analysis and TEM observations, an impurity phase of SrSiO 3 was identified additionally, as a result of the oxidation of the host SrSi 2 O 2 N 2 . In addition, the activator ions were also oxidized during baking in air, with divalent Eu 2+ changed into trivalent Eu 3 . It indicates that both of the oxidation of host and activators leads to the thermal degradation of SrSi 2 O 2 N 2 :Eu that is an irreversible decrease of luminescence. For (Sr,Ca)AlSin3:Eu (SCASN), the moisture-induced degradation was comprehensively investigated by treating it under a severe condition of high-pressure water steam. The degradation initiated at 150 o C, and the luminescence of SCASN was seen to be quenched quickly, with the powder sample being bleached after the treatment. Both of the microstructure and phase changed obviously with the oxidation, and the host turned finally into NH 3 , (Sr,Ca)Al 2 Si 2 O 8 and Ca(OH) 2 . By using a variety of spectroscopic, surface and microstructure analytic techniques, the degradation mechanism was clarified and proposed to occur via the oxidant-gas penetration mechanism through the moisture-enhanced oxidation of both the SCASN host and divalent europium.

Enhancing the sweetening power of lactose by enzymatic modification in the reformulation of dairy products (2020)

Lactose solutions of up to 50% ( w / v ) were incubated with lactases and glucose isomerases for subsequent implementation in dairy product samples to enhance sweetness. A degree of hydrolysis of &gt;90% and of isomerisation of 50% were attainable. The sensory sweetening power of lactose in solutions of up to 50% ( w / v ) can be enhanced 2–3 times. Based on sensory experiments, application of this bi‐enzymatic system in yoghurt and pudding samples allowed for a 10–20% ( w / w ) reduction in the total sugar content, whilst retaining equal sweetness. The growth of yoghurt starter cultures was not affected, yet furosine formation more than doubled in high heated, enzyme‐modified milk.

Objective To improve the diagnosis and treatment of the rupture of kidney graft artery after renal transplantation.Methods The cause of disease,clinical manifestations,surgical findings,treatment and pathological characteristics of eight cases with rupture of kidney graft artery were retrospectively analyzed.Results The rupture positions of graft artery were from 0.45 cm to 1.65 cm far from the position of anastomosis.Our findings revealed that four cases of graft artery were infected due to aspergilluses,two cases due to mucorales,and two due to bacteria,the diagnoses were confirmed by pathological examination.All the cases were returned to hemodialysis except two was dead with fungal sepsis after the removement of kidney transplant and administration of anti-fungal agents and antiseptics.Conclusion Rupture of kidney graft artery is a uncommon complication after renal transplantation.Early diagnosis,operation and initiation of specific treatment in addition to graft nephrectomy may improve the prognosis of this complication.
Performing a breast biopsy with a directional, vacuum-assisted biopsy instrument. (1997)

A recently developed method of minimally invasive breast biopsy involves use of a directional, vacuum-assisted instrument. Use of this instrument requires some changes in techniques and applications of breast biopsy, but it enables confident biopsy of breast lesions under both ultrasound (US) and stereotactic guidance. The device uses vacuum to pull tissue into the probe and to remove the specimen without withdrawing the probe each time. For stereotactic biopsy, to target the lesion, the probe is placed anterior or posterior to the lesion and stereotactic positioning views are obtained; for a US-guided procedure, the probe is advanced posterior to the lesion. Next, the direction that the probe aperture must be rotated to face the lesion is determined. Tissue samples are obtained at consecutive clock positions of 1 1/2-hour intervals to achieve contiguous sampling. At least 15 samples are obtained with an 11-gauge probe to acquire a minimum of 1,500 mg of tissue. If postbiopsy images reveal that the lesion has been removed, a percutaneous clip is placed to mark the biopsy site for follow-up examination and possible further treatment. Patients are examined the next day and given the biopsy results and treatment considerations, if needed; they are followed up approximately 1 week later to detect any complications (eg, discomfort, ecchymosis). By learning how to perform a directional, vacuum-assisted biopsy with either stereotactic or US guidance, the radiologist has an additional, valuable tool for bringing accurate breast biopsy to his or her community.
Prediction of antiviral drugs against African swine fever viruses based on protein–protein interaction analysis (2020)

The African swine fever virus (ASFV) has severely influenced the swine industry of the world. Unfortunately, there is currently no effective antiviral drug or vaccine against the virus. Identification of new anti-ASFV drugs is urgently needed. Here, an up-to-date set of protein-protein interactions between ASFV and swine were curated by integration of protein-protein interactions from multiple sources. Thirty-eight swine proteins were observed to interact with ASFVs and were defined as ASFV-interacting swine proteins. The ASFV-interacting swine proteins were found to play a central role in the swine protein-protein interaction network, with significant larger degree, betweenness and smaller shortest path length than other swine proteins. Some of ASFV-interacting swine proteins also interacted with several other viruses and could be taken as potential targets of drugs for broad-spectrum effect, such as HSP90AB1. Finally, the antiviral drugs which targeted ASFV-interacting swine proteins and ASFV proteins were predicted. Several drugs with either broad-spectrum effect or high specificity on ASFV-interacting swine proteins were identified, such as Polaprezinc and Geldanamycin. Structural modeling and molecular dynamics simulation showed that Geldanamycin could bind with swine HSP90AB1 stably. This work could not only deepen our understanding towards the ASFV-swine interactions, but also help for the development of effective antiviral drugs against the ASFVs.
Grape berry transpiration influences ripening and must composition in cv. Tempranillo (Vitis vinifera L.) (2022)

The implications of grape berry transpiration for the ripening process and final grape composition were studied. An experiment was conducted, under controlled conditions, with fruit-bearing cuttings of Vitis vinifera L. cv. Tempranillo. Three doses of the antitranspirant di-1-p-menthene were applied directly to the bunch at the onset of veraison: 1%, 5%, and 10% (v/v) (D1, D5, and D10, respectively). A treatment with bunches sprayed with water (D0) was also included as a control. Grape and bunch transpiration, and total soluble solids (TSS) accumulation rate decreased as the dose of antitranspirant increased, thus resulting in the lengthening of the ripening period. Bunch transpiration rates were linearly correlated with the elapsed time between veraison and maturity, and with the TSS accumulation rate. The evolution of pH, malic acid and total skin anthocyanins during ripening did not show remarkable changes as a consequence of the artificially reduced bunch transpiration. However, a decoupling between TSS and anthocyanins was observed. At maturity, the bunches treated with D10 had significantly lower must acidity and higher pH and extractable anthocyanin levels, these differences being likely associated with the lengthening of the ripening period. The results show a clear implication of grape transpiration for the ripening process and final grape composition, and give new hints on the direct application of antitranspirants to the bunch as a way to regulate sugar accumulation while avoiding the concurrent delay of color development.
Study of Performance Improvement for Dye-Sublimation Printer (2011)

Dye sublimation printer print is possible to print on the highresolution. But Dye sublimation printer receives high heat and pressure than Inkjet printer and Laser printer. Therefore, the surface paper is transformed, and there is a possibility of negatively affecting the print quality. Then, we verify the reason why the surface paper is transformed and Influence that transformation of surface paper gives print quality.

Selective Formation of Self-Organized InAs Quantum Dots Grown on Patterned GaAs Substrates by Molecular Beam Epitaxy (2006)

We have studied the formation of self-organized InAs quantum dots (QDs) on patterned GaAs substrates. To enhance the migration of the atoms, the InAs QDs were grown by periodic supply epitaxy. For InAs growth on line patterns that were parallel to the [110] direction, the InAs QDs were selectively formed on the A-planes. Conversely, no selective formation of InAs QDs was observed on line patterns, that were parallel to the [110] direction. This can be explained by the stability of the In atoms on the A-steps; they are more stable because they have only one dangling bond, and the other three bonds are attached to As atoms below them. Therefore, accumulated InAs on the A-steps can form QDs at an early stage. The µ-photoluminescence properties of the InAs QDs were studied, and strong emissions from the InAs QDs on the patterned areas were observed even at room temperature. Further work on this issue may reveal possibilities for controlling the exact position of a few InAs QDs.
Transforms Used in Electronic Image Processing (2009)

This chapter discusses several types of transforms that are commonly used in image processing. The most common transform, the Fourier transform, will be presented first, followed by several closely related transforms such as the Hadamard, Walsh, and discrete cosine transforms, which are used in the area of image compression. The chapter will end with the Hough transform, which is used to find straight lines in a binary image, and the Hotelling transform, which is commonly used to find the orientation of the maximum dimension of an object.

A short review of one-dimensional Fourier transforms will be presented to give the reader the necessary background to understand the properties of the two-dimensional Fourier transform used in electronic image processing. The Fourier transform is the most commonly used transform in image processing because of its relationship to linear system theory. Given an input to a linear system, the output is predicted using the complex operation of convolution or by simple multiplication using the Fourier transform. The Fourier transform/series was originally developed by the French mathematician Baptiste Joseph Fourier (1768-1830) to solve Laplace's differential equation (known as the Dirichlet problem) that described the conduction of heat (distribution of temperature) along an infinite conducting sheet. Fourier used a series of sine and cosine functions as a solution to the differential equation by solving for a set of unknown coefficients.
Technetium-99m(Sn2+)pyrophosphate in ischemic and infarcted dog myocardium in early stages of acute coronary occlusion: histochemical and tissue-counting comparisons. (1983)

We have investigated the pattern of accumulation of Tc-99m(Sn2+)pyrophosphate (Tc-99m PPi) in myocardial tissue of dogs during the early stages of acute occlusion of the left anterior descending coronary artery. Three groups were studied after: (a) 40 min occlusion followed by 6 hr reperfusion (n = 6); (b) 6 hr occlusion followed by one hour reperfusion (n = 5); and (c) 7 hr occlusion with no reperfusion (n = 4). Areas of myocardial infarction were defined with triphenyl-tetrazolium chloride (TTC) staining, and blood flow was determined with 9-mu radioactive microspheres. In Group C uptake in infarcted and peri-infarct areas was not enhanced, most likely owing to low flow. In Group B, with late reperfusion, Tc-99m PPi sequestration was increased in both infarcted and peri-infarcted tissues. In Group A, areas ischemic during occlusion but with normal flow and viability by TTC after 6 hr of reperfusion showed significant uptake of Tc-99m PPi (twice the uptake of nonischemic regions).
Toward Improving Similar Item Recommendation for a C2C Marketplace (2019)

This study stems from actual challenges that we face in building a recommender system at Bukalapak. Our existing recommendation system, which is an item-to-item collaborative filtering based on co-view method has helped users during their shopping journey by offering them similar items recommendation in the product detail page. However, our baseline system has not utilized the information on how the user perceives the recommendation offered in our recommendation widget. This paper discusses how we improve our recommendation system with point-wise Learning-to-Rank (LTR) method. We also present specific features that support the LTR performance. Finally, we evaluate the LTR model by offline evaluation metrics and online A/B test, where we compare our baseline by using the model to rerank the candidates item before presenting them as recommendation sets. By calculating the Click Through Rate (CTR), it shows that the LTR method can outperform the baseline by 1.63%.

SAFETY OF AMISELIMOD IN HEALTHY SUBJECTS: RESULTS FROM A PHASE 1 RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED STUDY (2021)

Abstract Objective To evaluate the safety profile of amiselimod, a selective sphingosine 1-phosphate receptor modulator which has been shown to regulate lymphocyte trafficking and is in development for the treatment of inflammatory bowel disease. Methods A randomized, double-blind, multiple-dose, placebo-controlled, parallel study with a nested crossover design evaluated the safety and tolerability profile of amiselimod. Healthy adults were randomized in a 2:1:1 ratio during a 28-day treatment period accordingly: a single dose of placebo followed by oral amiselimod (upwardly titrated in doses ranging from 0.4 to 1.6 mg to achieve 0.4 mg and 0.8 mg steady-state exposure; a single dose of oral moxifloxacin 400 mg followed by placebo; or placebo followed by a single dose of moxifloxacin 400 mg. The safety population included all subjects who received at least one dose of treatment. Adverse events (AE) and serious AEs were collected. Treatment-emergent AEs were defined as an AE that was starting or worsening at the time of or after study drug administration. Changes in clinical laboratory parameters (including lymphocyte counts), physical examinations, vital signs, and electrocardiogram parameters (including heart rate, PR, QRS, and QT intervals) were recorded. Subjects were permitted to withdraw if lymphocyte counts were ≤ 0.2 x 109/L. Results The safety population included 190 subjects of which 95 received amiselimod and 95 were in the combined moxifloxacin group. Subjects were 40% female, 83% white, and the mean (standard deviation) age was 39.0 (8.8) years. The discontinuation rate was 8% (n=8) in the amiselimod group and 4% (n=4) in the moxifloxacin group. Three subjects who received amiselimod discontinued because they met the stopping criteria for low lymphocyte counts. One subject experienced an amiselimod-related serious AE of atrial fibrillation on day 26 (after receiving amiselimod 1.6 mg for 3 of the preceding 4 days) that required hospitalization, cardioversion, and led to discontinuation. No deaths were reported. All other AEs were mild to moderate in severity. Decreased white blood counts were the most commonly reported TEAE, followed by headache and constipation (Table). Reductions in white blood counts returned to normal range after study discontinuation without sequelae. Decreased neutrophils, lymphocytes and hemoglobin, and increased creatine kinase, alanine aminotransferase, and aspartate aminotransferase were reported, all of which resolved without sequelae. The mean absolute lymphocyte count for amiselimod exhibited a gradual decrease from predose (1.681 thou/uL) to a nadir of 0.424 thou/uL on day 27 (Figure). Changes to vital signs, physical examinations, and ECG parameters were within normal limits. Conclusions Upwardly titrated doses of amiselimod ranging from 0.4 to 1.6 mg were generally well tolerated in healthy subjects.
Optical design of a solar collector for the advanced solar thermal electric conversion/process heat program (1977)

A technical feasibility study was carried out for a concentrating solar collector system with receiver at ground level to result in an optical design carried out in sufficient detail to enable the sponsor to evaluate cost and potential for using its technology. Potential problem areas were to be identified. The initial efforts consisted of literature searches and weekly meetings to discuss general concepts. Several potential systems were considered, but one configuration, the tower reflector-concentrator, was the only one that met requirements at reasonable technological risk. This system was adopted for detailed development and analysis. The second stage consisted of development of techniques for calculating the optical specifications, a study of funnel concentrators, which also required development of analytical tools and computer programs, and a review of materials and coatings for optical elements.
Proton-Ion Medical Machine Study (PIMMS), 2 (2000)

The Proton-Ion Medical Machine Study (PIMMS) group was formed following an agreement between the Med-AUSTRON (Austria) and the TERA Foundation (Italy) to combine their efforts in the design of a cancer therapy synchrotron capable of accelerating either light ions or protons. CERN agreed to support and host this study in its PS Division. A close collaboration was also set up with GSI (Germany). The study group was later joined by Onkologie-2000 (Czech Republic). Effort was first focused on the theoretical understanding of slow extraction and the techniques required to produce a smooth beam spill for the conformal treatment of complex-shaped tumours with a sub-millimetre accuracy by active scanning with proton and carbon ion beams. Considerations for passive beam spreading were also included for protons. The study has been written in two parts. The more general and theoretical aspects are recorded in Part I and the specific technical design considerations are presented in the present volume, Part II. An accompanying CD-ROM contains supporting publications made by the team and data files for calculations. The PIMMS team started its work in January 1996 in the PS Division and continued for a period of four years.
Multi-jet Merging with TMD Parton Branching (2022)

One of the main theoretical systematics in studies of final states with large jet multiplicities at high-energy hadron colliders is associated with the merging of QCD parton showers and hard-scattering matrix elements. We present a method to incorporate the physics of transverse momentum recoils due to initial-state shower evolution into multi-jet merging algorithms by using the concept of transverse momentum dependent (TMD) distributions and the associated parton branching. We investigate the dependence on the merging scale and illustrate the impact of the new method at the level of both exclusive and inclusive final-state observables by studying differential jet rates, transverse momentum spectra and multiplicity distributions, using vector boson + jets events at the LHC as a case study.
Spectra and eigenvectors of scale-free networks (2001)

We study the spectra and eigenvectors of the adjacency matrices of scale-free networks when bidirectional interaction is allowed, so that the adjacency matrix is real and symmetric. The spectral density shows an exponential decay around the center, followed by power-law long tails at both spectrum edges. The largest eigenvalue lambda1 depends on system size N as lambda1 approximately N1/4 for large N, and the corresponding eigenfunction is strongly localized at the hub, the vertex with largest degree. The component of the normalized eigenfunction at the hub is of order unity. We also find that the mass gap scales as N(-0.68).
1.5 GHz SAW bandpass filter using poly-crystalline diamond (1993)

Due to its high Young modulus, diamond has the highest acoustic wave velocity among all materials and thus it can be expected to be a candidate of the substrate for high frequency surface acoustic wave (SAW) devices. 15 μm thick poly-crystalline diamond deposited on a silicon substrate by hot-filament CVD was used as a substrate. For the piezoelectric material, ZnO film was deposited by RF sputtering. A 1.5 GHz bandpass filter was successfully demonstrated using a 1.5 μm line and space single electrode; additionally a 12.1 dB insertion loss including a 6 dB bi-directional loss was observed. The phase velocity of 8900 m/s and an electro-mechanical coupling constant of 1.76% were obtained for this filter. The propagation loss of this structure was estimated to be 3.9 dB- most of this is presumably losses in ZnO. This loss can be reduced by process refinement of ZnO deposition
