Active Illumination for the RealWorld (2017)

Active illumination systems use a controllable light source and a light sensor to measure properties of a scene. For such a system to work reliably across a wide range of environments it must be able to handle the effects of global light transport, bright ambient light, interference from other active illumination devices, defocus, and scene motion. The goal of this thesis is to develop computational techniques and hardware arrangements to make active illumination devices based on commodity-grade components that work under real world conditions. We aim to combine the robustness of a scanning laser rangefinder with the speed, measurement density, compactness, and economy of a consumer depth camera. Towards this end, we have made four contributions. The first is a computational technique for compensating for the effects of motion while separating the direct and global components of illumination. The second is a method that combines triangulation and depth from illumination defocus cues to increase the working range of a projector-camera system. The third is a new active illumination device that can efficiently image the epipolar component of light transport between a source and sensor. The device can measure depth using active stereo or structured light and is robust to many global light transport effects. Most importantly, it works outdoors in bright sunlight despite using a low power source. Finally, we extend the proposed epipolar-only imaging technique to time-of-flight sensing and build a low-power sensor that is robust to sunlight, global illumination, multi-device interference, and camera shake. We believe that the algorithms and sensors proposed and developed in this thesis could find applications in a diverse set of fields including mobile robotics, medical imaging, gesture recognition, and agriculture.
Crystal structure of Ir(acac-O,O)2(acac-C3)(pyridine) (2011)

Ir(acac-O,O)2(acac-C3)(pyridine), 1 is synthesized, and its crystal structure is determined by single crystal X-ray diffraction. In the complex, the central Ir(III) atom displays a distorted octahedral geometry wherein the equatorial positions are occupied by four oxygen atoms of two acetylacetone ligands, and the apical positions are coordinated by a carbon atom of one acetylacetone ligand and a nitrogen atom of pyridine.
Sound broadcasting from non-geostationary satellites (1992)

Briefly discusses research developments and future prospects for the use of highly inclined elliptical orbits (HEOs) for sound broadcasting. Whilst further study is required, it is believed that satellites with their wide coverage would form a necessary compliment to or perhaps enhance the viability of terrestrial systems. The first results of economic studies indicate that HEO techniques will make satellites attractive to broadcasters and that the consumer will be able to afford receivers, whilst making a contribution to broadcaster revenues.<

Li–Fraumeni Syndrome: Mutation of TP53 Is a Biomarker of Hereditary Predisposition to Tumor: New Insights and Advances in the Treatment (2022)

Li-Fraumeni syndrome (LFS) is a rare familial tumor predisposition syndrome with autosomal dominant inheritance, involving germline mutations of the <i>TP53</i> tumor suppressor gene. The most frequent tumors that arise in patients under the age of 45 are osteosarcomas, soft-tissue sarcomas, breast tumors in young women, leukemias/lymphomas, brain tumors, and tumors of the adrenal cortex. To date, no other gene mutations have been associated with LFS. The diagnosis is usually confirmed by genetic testing for the identification of <i>TP53</i> mutations; therefore, these mutations are considered the biomarkers associated with the tumor spectrum of LFS. Here, we aim to review novel molecular mechanisms involved in the oncogenic functions of mutant p53 in LFS and to discuss recent new diagnostic and therapeutic approaches exploiting <i>TP53</i> mutations as biomarkers and druggable targets.
Fluorometric Determination of Thiamine Vitamers in Chicken (1992)

Abstract A comparison was made of the direct determination of thiamine In acidified heated chicken extracts, by either flow injection or chromatographic determination, with the standard method (acid and enzyme digestion, adsorption, and elutlon, followed by the fluorometric determination of thiochrome extracted by Isobutanol from K3Fe(CN)6-treated eluates). Liquid chromatography of extracts, followed by oxidation of thiamine vitamers to thlochromes, showed 1 light scatter emission peak and 2 thlochromes, the latter corresponding to thiamine and thiamine monophosphate. Both forms were determined quantitatively by flow Injection determination, the lower detection limit of which was about 60 femtomol. The determination was linear from 0.1 ng to 10 μg thlamlne/mL, and the pooled coefficient of variation was 4%. The determination of thiamine in chicken extracts provides a nondestructive method for determining thiamine and Its phosphate esters, either In toto by flow Injection determination or as individual components by chromatography.
A Stereoselective Pharmacophoric Model of the Serotonin Re‐uptake Site (1997)

Exhaustive conformational analyses on four selective serotonin reuptake inhibitors resulted in a pharmacophoric model explaining observed differences in enantioselectivities. A number of test compounds from a diverse set of chemical structures was included in the evaluation of the model. Furthermore, selectivity towards noradrenaline reuptake is explained.
IllumiRoom (2013)

IllumiRoom is a proof-of-concept system that augments the area surrounding a television with projected visualizations to enhance traditional gaming experiences. Our system demonstrates how projected visualizations in the periphery can negate, include, or augment the existing physical environment and complement the content displayed on the television screen. We can change the appearance of the room, induce apparent motion, extend the field of view, and enable entirely new physical gaming experiences. Our system is entirely self-calibrating and is designed to work in any room.
Five-coordination in complexes of 2-(3,5-Dimethylpyrazol-1-yl)quinoline, a sterically hindered diimine system (1984)

The bidentate diimine-type ligand 2-(3,5-dimethylpyrazol-1-yl)quinoline forms mono complexes with the bivalent chlorides of iron, cobalt, nickel and copper. These complexes are magnetically dilute, but electronic spectral data indicate that, except for the cobalt complex which is tetrahedral, the metal atoms are five-coordinate and hence a chloro-bridged structure is proposed. The cobalt(II) complex readily adds a water molecule, and structure determination by X-ray diffraction shows that the complex aquadichloro[2-(3,5-dimethylpyrazol-1-yl)quinoline]cobalt(II) is monomeric and five-coordinate, the coordination environment approximating trigonal bipyramidal.
Nonuniformly Activated Catalysts (1987)

Abstract In most theoretical and experimental studies in the area of heterogeneous catalysis, the distribution of catalytically active material within three-dimensional carriers has been assumed to be uniform. An extensive literature exists [1, 2] dealing with interactions between chemical and physical transport phenomena within such porous catalysts. The effects of intraparticle mass and heat diffusional resistances in catalysts exhibiting uniform activity distributions have been extensively studied in terms of point and overall effectiveness, selectivity, and yield, as well as in terms of concentration and temperature profiles within catalyst particles and chemical reactors.
Refined Mean Field Analysis of the Gossip Shuffle Protocol -- extended version -- (2020)

Gossip protocols form the basis of many smart collective adaptive systems. They are a class of fully decentralised, simple but robust protocols for the distribution of information throughout large scale networks with hundreds or thousands of nodes. Mean field analysis methods have made it possible to approximate and analyse performance aspects of such large scale protocols in an efficient way. Taking the gossip shuffle protocol as a benchmark, we evaluate a recently developed refined mean field approach. We illustrate the gain in accuracy this can provide for the analysis of medium size models analysing two key performance measures. We also show that refined mean field analysis requires special attention to correctly capture the coordination aspects of the gossip shuffle protocol.
Characterization of atrial flutter. Studies in man after open heart surgery using fixed atrial electrodes. (1979)

Studies were performed using bipolar atrial wire electrodes to record atrial electrograms and to pace the atria in 27 patients who developed atrial flutter after open heart surgery. Two types of atrial flutter, classic or type I atrial flutter, and type II atrial flutter, were identified. Both types of atrial flutter were characterized by uniformity of the beat-to-beat atrial cycle length, morphology, polarity, and amplitude of the recorded bipolar atrial electrogram. Both types sometimes manifested a beat-to-beat electrical alternans, which in turn was sometimes associated with an alternans in beat-to-beat cycle length. The initial basis of separation of types I and II atrial flutter was that type I atrial flutter was always influenced by rapid atrial pac- ing from the high right atrium, and type II atrial flutter was not. Two additional observations suggested that types I and II atrial flutter were different, although related, rhythms: 1) In four patients, type II atrial flutter was present after termination of rapid atrial pacing used to treat type I atrial flutter; 2) in two patients, type II atrial flutter changed to type I atrial flutter in a one-step fashion. The range of rates of the two types of atrial flutter were also different type I atrial flutter was slower (range 240-338 beats/min) than type II (range 340-433 beats/min). We concluded that type II atrial flutter is a distinct rhythm which may be intermediate between classic, or type I, atrial flutter and atrial fibrillation.
Presence of late gadolinium enhancement in Duchenne muscular dystrophy patients is associated with age and global ventricular function (2012)

Background The Duchenne muscular dystrophy (DMD) associated cardiac disease results in significant morbidity and mortality usually resulting in death by the second to third decade of life. End-stage cardiac pathology consists of alternating areas of myocyte hypertrophy, atrophy and fibrosis manifesting as late gadolinium enhancement (LGE) on cardiac magnetic resonance imaging (CMR) evaluation. There has been considerable interest in detecting the presence of LGE, and previous studies have associated LGE with global ventricular dysfunction as assessed by ejection fraction (EF). However, given the genetic origins and underlying pathogenesis of DMDassociated cardiac disease, we hypothesized that LGE is prevalent in patients without overt disease.
QS1: Creeping Fat Adipocytes Drive Intestinal Fibrosis Through Adipocyte-to-fibroblast Conversion in a Novel Model of Inflammatory Bowel Disease (2021)

Purpose: Crohn’s disease (CD) is a subtype of inflammatory bowel disease (IBD) characterized by patchy, transmural inflammation throughout the digestive tract and creeping fat formation. Thirty percent of CD patients develop strictures, eighty percent of which will require surgery. Creeping fat is associated with stricture formation, but its role in intestinal fibrosis remains unclear. Here, we present a novel surgical model of intestinal fibrosis and show by lineage tracing that creeping fat adipocytes convert to fibroblasts that contribute to fibrosis. Methods: We developed a novel surgical model of IBD that avoids the chronic use of caustic agents by creating a longitudinal, anti-mesenteric colotomy in the mouse transverse colon that is closed transversally. We performed Masson’s trichrome staining to assess collagen deposition. Finally, we performed lineage tracing of mature adipocytes in Adiponectin-Cre; mTmG mice and characterized adipocyte-derived cells by immunostaining. Results: Our surgical model mimics key features of human strictures, including the formation of creeping fat around the injury site, increased bowel wall thickness, collagen deposition, and transmural adipocyte infiltration by post-operative day (POD) 7. Immunostaining for adipocyte and fibroblast markers confirmed the presence of transmural adipocytes adjacent to fibroblasts. Lineage tracing of mature adipocytes in Adiponectin-Cre; mTmG mice revealed adipocyte-derived cells that infiltrate the wound site that lose expression of adipocyte lineage markers, gain expression of fibroblast markers, produce collagen, and respond to TGF-β signaling. Conclusions: Our novel surgical colotomy model represents a viable approach to study intestinal fibrosis and creeping fat without the long-term use of caustic agents. Lineage tracing of mature creeping fat adipocytes demonstrates that adipocytes convert to fibroblasts that infiltrate the injury site and participate in fibrotic responses. Taken together, these findings suggest that creeping fat contributes to intestinal fibrosis in part through the local conversion of adipocytes to fibroblasts.
Survey of support structures for offshore wind turbines (2017)

This paper aims to provide an overview of the state-of-the-art in offshore wind turbines, including an introduction to general design principles and the foundations. For use in shallow water, gravity foundations or buckets (caissons) are currently used, whereas monopiles are being applied for medium depth water. It is foreseen that future larger wind turbines (say 10 MW nominal power output, 160 m rotor diameter) in deeper water will be based on a tripod foundation. For very deep waters, such as around Japan, floating wind turbines are also being considered.
Handwriting Recognition through Novel Combinational Segmentation Technique and Iterative Blocks Features (2018)

We propose a novel technique for segmentation of the handwritten answers written in continuous writings by the candidates during theory based examinations. We estimate digital information from the handwritten words. The problem with cursive writings is that the neighboring characters may be overlapping or may be some times away from each other. Also all the characters are not of same size. A single length window cannot segment all the characters while an adaptive length window would either require multiple scans of the image or multiple windows might be needed, increasing the computational complexity. Here, we propose a novel combinational segmentation scheme where variable length cuts are of the word image are generated as tentative segments and the length of cuts depends upon the vertical pixel density threshold. These segments may have some segments with deficient characters or excess parts of neighboring characters. So recombination of these segments with nearest segments is done to generate final segments. The advantage of the method is that we can segment any handwriting. Then, we train the system to identify a character through the proposed iterative blocks scheme. The features extracted are density per block and number of junctions and end points per block. Text written by the same author is used for the testing. We have tested for 10 subjects with character recognition accuracy more than 90%.
SwinFuse: A Residual Swin Transformer Fusion Network for Infrared and Visible Images (2022)

The existing deep learning fusion methods mainly concentrate on the convolutional neural networks, and few attempts are made with transformer. Meanwhile, the convolutional operation is a content-independent interaction between the image and convolution kernel, which may lose some important contexts and further limit fusion performance. Towards this end, we present a simple and strong fusion baseline for infrared and visible images, namely <i>Residual Swin Transformer Fusion Network</i>, termed SwinFuse. Our SwinFuse includes three parts: the global feature extraction, fusion layer and feature reconstruction. In particular, we build a fully attentional feature encoding backbone to model the long-range dependency, which is a pure transformer network and has a stronger representation ability compared with the convolutional neural networks. Moreover, we design a novel feature fusion strategy based on <i>L</i><sub>1</sub>-norm for sequence matrices, and measure the corresponding activity levels from row and column vector dimensions, which can well retain competitive infrared brightness and distinct visible details. Finally, we testify our SwinFuse with nine state-of-the-art traditional and deep learning methods on three different datasets through subjective observations and objective comparisons, and the experimental results manifest that the proposed SwinFuse obtains surprising fusion performance with strong generalization ability and competitive computational efficiency. The code will be available at https://github.com/Zhishe-Wang/SwinFuse.

Training intonational phrasing rules automatically for English and Spanish text-to-speech. (1994)

Abstract We describe a procedure for acquiring intonational phrasing rules for text-to-speech synthesis automatically, from annotated text, and some evaluation of this procedure for English and Spanish. The procedure employs decision trees generated automatically, using Classification and Regression Tree techniques, from text corpora which have been hand-labeled by native speakers with likely locations of intonational boundaries, in conjunction with information available about the text via simple text analysis techniques. Rules generated by this method have been implemented in the English version of the Bell Laboratories Text-to-Speech System and have been developed for the Mexican Spanish version of that system. These rules currently achieve better than 95% accuracy for English and better than 94% for Spanish.
Kinetico-mechanistic Study on the Oxidation of Biologically Active Iron(II) Bis(thiosemicarbazone) Complexes by Air. Importance of NH···O2 Interactions As Established by Activation Volumes (2017)

Air oxidation of methanolic solutions of biologically active tridentate pyridyl thiosemicarbazone (TSC) complexes of the general formula [Fe<sup>II</sup>(TSC)<sub>2</sub>] has been studied at varying dioxygen concentrations, temperatures, and pressures. The data collected indicate that the activation entropy of the reaction increases linearly with the redox potential of the complexes in a more definite way than the activation enthalpy. However, a very distinct behavior is observed for the values of the activation volumes, which do not follow the expected entropy-volume parallel trend for all of the systems studied. The involvement of important interactions between the terminal NH groups of the coordinated TSC ligand and molecular dioxygen has been found to be significant by measurements carried out at varying hydrostatic pressures. Kinetic experiments run on analogous N-deuterated complexes confirm the importance of these noncovalent interactions, which are weaker for the less acidic ND groups. These interactions show the existence of an ordering/expansion process upon going from the reactants to the transition state, whenever an interaction between the polar terminal amino groups and dioxygen can be established.
Evaporation-based Ge/.sup.68 Ga Separation (2023)

Micro concentrations of .sup.68 Ga in secular equilibrium with .sup.68 Ge in strong aqueous HCl solution may readily be separated in ionic form from the .sup.68 Ge for biomedical use by evaporating the solution to dryness and then leaching the .sup.68 Ga from the container walls with dilute aqueous solutions of HCl or NaCl. The chloro-germanide produced during the evaporation may be quantitatively recovered to be used again as a source of .sup.68 Ga. If the solution is distilled to remove any oxidizing agents which may be present as impurities, the separation factor may easily exceed 10.sup.5. The separation is easily completed and the .sup.68 Ga made available in ionic form in 30 minutes or less.
Ion Chromatographic Determination of Residual Phase Transfer Catalyst in Active Pharmaceutical Ingredient (2009)

A new ion chromatography method with non-suppressed conductivity detection has been developed for the quantification of residual phase transfer catalyst-tetrabutylammonium bromide (TBAB) in an active pharmaceutical drug, Levetiracetam. Separation conditions are optimized to get a clear separation of TBAB from drug impurities using a Metrosep Cation C2-150 column. Conditions are also optimized to separate tetramethylammonium bromide, tetraethylammonium bromide, and tetrapropylammonium bromide, which are also used as phase transfer catalysts in several syntheses. Method performance was checked for selectivity, linearity, limit of quantification, limit of detection, accuracy, and precision. The method has superior performance with linearity r(2) > or = 0.9999, recovery from 94.7% to 96.5%, precision < or = 0.74%. In-line preconcentration is used to achieve limits of detection and quantification of 39 ng and 118 ng of TBAB, which corresponds to 1.56 and 4.72 microg/g of TBAB with respect to sample weight. The proposed method can be used for routine quality assurance analysis in the pharmaceutical industry.
Mechanical properties of 3D bioprinted dermis: characterization and improvement (2019)

Bioprinting is a promising way to create native-equivalent tissues for skin replacement in several pathologies and trauma. These last few years, various constructs have been reported, composed of fibroblasts and keratinocytes used to recapitulate the dermo-epidermal structure. However, the ability to control and characterize the mechanical properties of such constructs is a critical point to insure the transfer of these engineered products to clinic in a near future. In the present study, we had investigated the modulation of the biomechanics of a bioprinted dermis model through physical constrain during tissue maturation. Two passive tension devices were then designed and tested to mature the tissue after printing. Decrease in tissue retraction and increase of collagen I densities, associated to modulations of Young’s modulus were obtained after 20 days of tissue maturation. Taken together, these results attest for the first time in literature of promising methods to modulate the mechanical properties of bioprinted skin models.
