Combination of Titanium Oxide and a Conjugated Polyelectrolyte for High‐Performance Inverted‐Type Organic Optoelectronic Devices (2011)

Interface engineering by combination of TiOx and a conjugated polyelectrolyte as an electron transport layer modifies the electrical contact between a metal electrode and an organic active layer with well-aligned frontier orbital energy levels for efficient charge transport. This results in remarkable improvements in the device performance of inverted polymer solar cells and polymer light-emitting diodes.

Protection of broiler breeders by an inactivated combined water-in-oil-in-water viral vaccine. (1998)

A four-component vaccine, prepared by combining the single vaccines, contains subunits of Newcastle disease and infectious bronchitis viruses, as well as whole inactivated infectious bursal disease and egg drop syndrome viruses. The vaccine is prepared in the form of a low-viscosity water-in-oil-in-water emulsion with low mineral oil content. Heavy breeders were vaccinated at the age of 20 weeks by intramuscular administration of 0.5 ml vaccine/bird in an experiment carried out under field conditions, involving 5000 female and 450 male parents. The birds had previously been vaccinated with live vaccines according to an obligatory field vaccination programme. Vaccination with the WOWE vaccine near the point of lay elicited serological responses protecting both the parents and their progeny. Each of the antigens administered in the four-component vaccine was as effective as the respective single component vaccine. The mortality, recorded during the 31-week experimental period, was 6.2%. Mortality and morbidity were not triggered by viruses against which vaccination was carried out. Egg production was not affected by the vaccination and was 170.2 eggs per hen during the 28-week production period.
Kinetic Modeling of Coke Oxidation of a Ferrierite Catalyst (2006)

Kinetic models describing coke oxidation were derived for purposes of designing a catalyst regeneration unit and to gain information on coke oxidation kinetics. The coke was formed during an alkene skeletal isomerization reaction on a ferrierite catalyst. Experiments were performed according to the temperature-programmed oxidation technique at several oxygen concentrations and heating rates. The parameters of the models were estimated by nonlinear regression. A power-law model with parametrized order of oxygen concentration described the experimental results adequately. Three other successful models, which were based on assumed reaction mechanisms, shared two main characteristics: the formation of a reactive oxygen intermediate in a fast equilibrium reaction, and the formation of CO and CO2 from one or more common precursors. All estimated parameters of the models were in a physically meaningful range.
Relation between Responsiveness to Neurotransmitters and Complexity of Epileptiform Activity in Rat Hippocampal CA1 Neurons (2002)

The results suggest that the reduced responses to neurotransmitters of the CA1 neurons appear to be closely related to the onset of EA. Furthermore, these neurons show that the changes in responsiveness are closely parallel to the decrease of degree of complexity of firing series during penicillin epileptogenesis.
Blind Deblurring Using GANs (2019)

Deblurring is the task of restoring a blurred image to a sharp one, retrieving the information lost due to the blur. In blind deblurring we have no information regarding the blur kernel. As deblurring can be considered as an image to image translation task, deep learning based solutions, including the ones which use GAN (Generative Adversarial Network), have been proven effective for deblurring. Most of them have an encoder-decoder structure. Our objective is to try different GAN structures and improve its performance through various modifications to the existing structure for supervised deblurring. In supervised deblurring we have pairs of blurred and their corresponding sharp images, while in the unsupervised case we have a set of blurred and sharp images but their is no correspondence between them. Modifications to the structures is done to improve the global perception of the model. As blur is non-uniform in nature, for deblurring we require global information of the entire image, whereas convolution used in CNN is able to provide only local perception. Deep models can be used to improve global perception but due to large number of parameters it becomes difficult for it to converge and inference time increases, to solve this we propose the use of attention module (non-local block) which was previously used in language translation and other image to image translation tasks in deblurring. Use of residual connection also improves the performance of deblurring as features from the lower layers are added to the upper layers of the model. It has been found that classical losses like L1, L2, and perceptual loss also help in training of GANs when added together with adversarial loss. We also concatenate edge information of the image to observe its effects on deblurring. We also use feedback modules to retain long term dependencies

Synthesis of γ-aminobutyric acid analogues of restricted conformation. Part 1. The 2-aminocycloalkylacetic acids (1982)

The syntheses of cis- and trans-2-aminocyclopropyl, -cyclobutyl, -cyclopentyl, and -cyclohexylacetic acids as γ-aminobutyric acid analogues of restricted conformation are described. Mass spectral evidence fully supports the stereochemical assignments of the configurational isomers.
Software-Defined Device-to-Device (D2D) Communications in Virtual Wireless Networks With Imperfect Network State Information (NSI) (2015)

Software-defined networking (SDN) and network function virtualization (NFV) are a promising system architecture and control mechanism for future networks. Although some works have been done on wireless SDN and NFV, recent advancements in device-to-device (D2D) communications are largely ignored in this novel framework. In this paper, we study the integration of D2D communication in the framework of SDN and NFV. An inherent challenge in supporting software-defined D2D is the imperfectness of network state information, including channel state information (CSI) and queuing state information, in virtual wireless (QSI) networks. To address this challenge, we formulate the resource sharing problem in this framework as a discrete stochastic optimization problem and develop discrete stochastic approximation algorithms to solve this problem. Such algorithms can reduce the computational complexity compared with exhaustive search while achieving satisfactory performance. Both the static wireless channel and time-varying channels are considered. Extensive simulations show that users can benefit from both wireless network virtualization and software-defined D2D communications, and our proposed scheme can achieve considerable performance gains in both system throughput and user utility under practical network settings.
Smart radio‐frequency identification tag for diaper moisture detection (2015)

A passive smart tag is described that responds to dampness in diapers once a pre-defined threshold value is reached. A high-frequency (HF) system at 13.56 MHz is used as this allows operation through water or human tissues with less absorption that would occur for an ultra-HF signal. A circular spiral coil and swelling substrate facilitate a reaction to dampness that can be detected without contact to the diaper wearer. A prototype design is simulated and measured results are provided together with a demonstration of a tag integrated into a worn diaper.
A modular test structure for CMOS mismatch characterization (2003)

In this work a new test structure for mismatch characterization of CMOS technologies is presented. The test structure is modular, with a reduced area and it can be inserted in the space between the dies (scribe lines) on the wafers. The test structure has been implemented in a standard 0.18-/spl mu/m digital CMOS technology.
An Unexpected Outcome During Testing of Commercially Available Demineralized Bone Graft Materials (2001)

Although the volume of Grafton product per kilogram of body weight used in this study was approximately eight times the maximum volume used in humans, the authors believe that this data must be reported because this product is used substantially in clinical settings. In addition, the osteoinductive performance and relative safety of the nonallograft components in all commercially available demineralized bone grafts are not known.
A theoretical model to predict the low-frequency sound absorption of a Helmholtz resonator array (2006)

A theoretical method based on mutual radiation impedance is proposed to compute the sound absorption performance of a Helmholtz resonator array in the low-frequency range. Any configuration of resonator arrangement can be allowed in the method, while all the resonators may or may not be identical. Comparisons of the theoretical predictions with those done by the past studies or experiments show that the present method can accurately predict the absorption performance in more general cases.
A safe, efficient algorithm for regression test selection (2002)

Regression testing is a necessary but costly maintenance activity aimed at demonstrating that code has not been adversely affected by changes. A selective approach to regression testing selects tests for a modified program from an existing test suite. A new technique for selective regression testing is presented. The proposed algorithm constructs control dependence graphs for program versions and uses these graphs to determine which tests from the existing test suite may exhibit changed behavior on the new version. Unlike most previous techniques for selective retest, the algorithm selects every test from the original test suite that might expose errors in the modified program, and does this without prior knowledge of program modifications. The algorithm handles all language constructs and program modifications and is easily automated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Self-expanding metallic stents for small vessels: an experimental evaluation. (1987)

Thirty-three self-expanding metallic stents were placed in 24 arterial segments of the hind legs and nine arteries of the abdominal viscera in seven dogs. Twelve 5-mm stents, eight 4-mm stents, and 13 3-mm stents were inserted. Follow-up ranged from 4 to 30 weeks. All 4-mm and 5-mm stents were patent at follow-up. Seven (54%) of the 3-mm stents remained patent. Stent wires were completely covered by a proliferation of the intima. No stent migration, occlusion of side branches, or vessel wall perforation was observed. A stent/artery ratio (SAR) was computed using stent and recipient vessel diameters. Good vascular patency was observed when the SAR was less than or equal to 1.2. An SAR greater than 1.2 was associated with immediate spasm, immediate or delayed thrombosis, or excessive intimal proliferation. Selection of correct stent size is a major determinant of patency in small arteries.
Three-dimensional finite element modelling of high-speed milling of Inconel 718 (2004)

The paper details research and development of a three-dimensional finite element (FE) model to simulate the ball nose end milling process using a commercial Lagrangian based code, ABAQUS Explicit. An elastic—plastic constitutive relationship was employed for the Inconel 718 workpiece material, which took account of inertia, strain hardening, strain rate and temperature on the material's flow stress. Associated yield stress behaviour was determined experimentally using an elevated strain rate and temperature compression testing (up to 100s −1 850°C respectively), with the former subsequently extrapolated to the levels encountered in metal cutting. Ball nose end mill geometry was based on commercial tools and was created externally on a computer aided design (CAD) system and imported into the FE domain. Different cutting speeds were simulated with chip shape, cutting forces and temperature results detailed for the initial cut. Resultant cutting forces were found to be essentially constant across the range of speeds simulated, while average cutting temperatures increased with cutting speed, although not dramatically, both of which agreed with trends from experimental work.
Stellenwert pflanzlicher Antitussiva und Expektorantien. Symptomatische Phytotherapie bei Husten (2008)

Abstract Die Inzidenz von Erkrankungen des Respirationstraktes steigt in Deutschland stark an, dies betrifft insbesondere die chronischen Erkrankungen wie die chronisch obstruktive Lungenerkrankung und das Asthma bronchiale. Der Stellenwert von pflanzlichen Drogen und ihren Zubereitungen ist bei diesen Erkrankungen bisher kaum zu beurteilen, da das Spektrum an verfügbaren Expektorantien und Antitussiva zwar relativ breit ist, diese jedoch ganz überwiegend bei akuten unkomplizierten Erkrankungen des Respirationstraktes eingesetzt werden und zwar immer mehr im Bereich der Selbstmedikation. Ein kompetenter Umgang mit Phytopharmaka ist jedoch bei allen Atemwegserkrankungen essenziell; die infolge der fehlenden Erstattungsfähigkeit mittlerweile überwiegende Selbstmedikation sollte arztgestützt erfolgen.

A Synthetic Alternative to Canonical One-Carbon Metabolism (2017)

One-carbon metabolism is an ubiquitous metabolic pathway that encompasses the reactions transferring formyl-, hydroxymethyl- and methyl-groups bound to tetrahydrofolate for the synthesis of purine nucleotides, thymidylate, methionine and dehydropantoate, the precursor of coenzyme A. An alternative cyclic pathway was designed that substitutes 4-hydroxy-2-oxobutanoic acid (HOB), a compound absent from known metabolism, for the amino acids serine and glycine as one-carbon donors. It involves two novel reactions, the transamination of l-homoserine and the transfer of a one-carbon unit from HOB to tetrahydrofolate releasing pyruvate as coproduct. Since canonical reactions regenerate l-homoserine from pyruvate by carboxylation and subsequent reduction, every one-carbon moiety made available for anabolic reactions originates from CO<sub>2</sub>. The HOB-dependent pathway was established in an Escherichia coli auxotroph selected for prototrophy using long-term cultivation protocols. Genetic, metabolic and biochemical evidence support the emergence of a functional HOB-dependent one-carbon pathway achieved with the recruitment of the two enzymes l-homoserine transaminase and HOB-hydroxymethyltransferase and of HOB as an essential metabolic intermediate. Escherichia coli biochemical reprogramming was achieved by minimally altering canonical metabolism and leveraging on natural selection mechanisms, thereby launching the resulting strain on an evolutionary trajectory diverging from all known extant species.

Direct electrosynthesis of pure aqueous H <sub>2</sub> O <sub>2</sub> solutions up to 20% by weight using a solid electrolyte (2019)

Hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) synthesis generally requires substantial postreaction purification. Here, we report a direct electrosynthesis strategy that delivers separate hydrogen (H<sub>2</sub>) and oxygen (O<sub>2</sub>) streams to an anode and cathode separated by a porous solid electrolyte, wherein the electrochemically generated H<sup>+</sup> and HO<sub>2</sub> <sup>-</sup> recombine to form pure aqueous H<sub>2</sub>O<sub>2</sub> solutions. By optimizing a functionalized carbon black catalyst for two-electron oxygen reduction, we achieved >90% selectivity for pure H<sub>2</sub>O<sub>2</sub> at current densities up to 200 milliamperes per square centimeter, which represents an H<sub>2</sub>O<sub>2</sub> productivity of 3.4 millimoles per square centimeter per hour (3660 moles per kilogram of catalyst per hour). A wide range of concentrations of pure H<sub>2</sub>O<sub>2</sub> solutions up to 20 weight % could be obtained by tuning the water flow rate through the solid electrolyte, and the catalyst retained activity and selectivity for 100 hours.
Multilevel interconnection for half-micron ULSI's (2003)

In order to integrate half-micron experimental CMOS and BiCMOS LSIs, multilevel interconnection process technology utilizing relatively conventional techniques has been developed. Some design rules are 0.8- mu m metal line and 0.6- mu m space for the first and the second level. To achieve these requirements, dielectric planarization techniques were adopted. Heavily doped BPSG glass flow was used to cover underlying poly steps, and spin-on-glass planarization was used at the metal steps. Tungsten (W) was selected for the first-level wiring. Although the step coverage of the sputtered W film at the reflow tapered 0.6- mu m contact hole was poor, high current capability was observed due to the high electromigration immunity of W. At via holes, step coverage was slightly improved using shallow voltage bias sputtering of Al. Al/TiN layered metallization was used for the second to fourth-level wirings to maintain stress migration immunity. At the third and fourth levels, design rules were widened because of the focus depth.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Artifact‐resistant motion estimation with a patient‐specific artifact model for motion‐compensated cone‐beam CT (2013)

Using the artifact model allows to accurately estimate and compensate for patient motion, even if the initial reconstructions are of very low image quality. Using our approach together with a cyclic registration algorithm yields a combination which shows almost no sensitivity to sparse-view artifacts and thus ensures both high spatial and high temporal resolution.
D3Feat: Joint Learning of Dense Detection and Description of 3D Local Features (2020)

A successful point cloud registration often lies on robust establishment of sparse matches through discriminative 3D local features. Despite the fast evolution of learning-based 3D feature descriptors, little attention has been drawn to the learning of 3D feature detectors, even less for a joint learning of the two tasks. In this paper, we leverage a 3D fully convolutional network for 3D point clouds, and propose a novel and practical learning mechanism that densely predicts both a detection score and a description feature for each 3D point. In particular, we propose a keypoint selection strategy that overcomes the inherent density variations of 3D point clouds, and further propose a self-supervised detector loss guided by the on-the-fly feature matching results during training. Finally, our method achieves state-of-the-art results in both indoor and outdoor scenarios, evaluated on 3DMatch and KITTI datasets, and shows its strong generalization ability on the ETH dataset. Towards practical use, we show that by adopting a reliable feature detector, sampling a smaller number of features is sufficient to achieve accurate and fast point cloud alignment.[code release](https://github.com/XuyangBai/D3Feat)
Concept Similarity Matching Based on Semantic Distance (2008)

With the application of semantic Web service and semantic Grid service, the similarity measure between services are more and more important in the processing of service matching. By formally defining the similarity of semantic services, useful information can be obtained about their similarity and compatibility. In this paper, we propose a concept similarity matching method based on semantic distance in service matching. Uses OWL-S to descript service, the algorithm computes semantic similarity of service in four macro steps. At last, we provide an experimental comparison of our method against traditional similarity measures, and prove empirically the benefits of our approach.
