Maintaining the artemisinin content through direct and indirect in vitro regeneration and their assessment of variations with the field grown mother plants of Artemisia annua L. (2012)

An efficient protocol for maintaining the artemisinin content in tissue culture and high frequency of in vitro direct and indirect regenerations of multiple shoots of high artemisinin yielding genotypes of Artemisia annua has been developed and their comparison with field grown mother plant has been carried out. The eleven elite genotypes (containing more than 1% artemisinin) were tested on seven different modified media formulations. Modified half MS (Murashige and Skoog’s) media containing 100 mg L−1 myo-inositol, 0.5 g L−1 casine hydrolysate, 5 mg L−1 biotin, 2 mL L−1 RT (Revised Tobacco) vitamin stock, 0.5 mg L−1 BAP and 0.01 mg L−1 NAA showed best regeneration while, above modified MS medium containing 0.2 mg L−1 BAP and 0.2 mg L−1 NAA showed maximum shoot multiplication with maintained artemisinin content. Based on the chemical profiles of both the systems, minor difference was observed in their artemisinin content. A large scale culture of these plants maintained the normal growth index along with the artemisinin content and could be a better alternative to maintain the high artemisinin yielding genotypes with their genetic constraint in specific media combinations and also used as base material for further genetic improvement.
Raman labeled nanoparticles: characterization of variability and improved method for unmixing (2012)

Raman spectroscopy can differentiate the spectral fingerprints of many molecules, resulting in potentially high multiplexing capabilities of Raman-tagged nanoparticles. However, accurate quantitative unmixing of Raman spectra is challenging because of potential overlaps between Raman peaks from each molecule as well as slight variations in the location, height and width of the very narrow peaks. If not accounted for properly, even minor fluctuations in the spectra may produce significant error which will ultimately result in poor unmixing accuracy. The objective of our study was to develop and validate a mathematical model of the Raman spectra of nanoparticles to unmix the contributions from each nanoparticle allowing simultaneous quantitation of several nanoparticle concentrations during sample characterization. We developed and evaluated an algorithm for quantitative unmixing of the spectra, called Narrow Peak Spectral Algorithm (NPSA) . Using NPSA, we were able to successfully unmix Raman spectra from up to 7 Raman nanoparticles after correcting for the spectral variations of 30% in intensity and shifts in peak locations of up to 10 cm<sup>-1</sup> which is equivalent to 50% of the full width at half maximum (FWHM). We compared the performance of NPSA to the conventional least squares analysis (LS), error in NPSA is approximately 50% lower than LS. The error in estimating the relative contributions of each nanoparticle using NPSA are in the range of 10-16% for equal ratios and 13-19% for unequal ratios for unmixing of 7 composite organic - inorganic nanoparticles (COINs) whereas the errors using the traditional least squares approach were in the range of 25-38% for equal ratios and 45-68% for unequal ratios. Here, we report for the first time, the quantitative unmixing of 7 nanoparticles with maximum RMS % error less than 20%.

L'instrumentation de l'action publique (2014)

Comment s'organise l'action collective ? Comment les acteurs coopèrent-ils ? La recherche en sciences sociales a donné des réponses très diverses à ces questions. Cet ouvrage propose de centrer l'attention sur les aspects concrets et sur les supports matériels de l'action collective : les instruments, les outils et les dispositifs tels qu’ils sont aujourd’hui mobilisés pour analyser les marchés, le capitalisme, les entreprises et différentes formes d’action collective liées à l’autorité publique. Dix ans après la parution de Gouverner par les instruments, ce nouvel opus dresse un bilan des débats et des controverses sur l’instrumentation en dialoguant avec d’autres champs d’études (sciences de gestion, histoire et économie) et discute la notion d’instrumentation à partir de travaux récents portant sur le climat, les services environnementaux,les droits de propriété, la dette publique, les journées mémorielles, la gestion des squats, etc. Une richesse des débats qui confirme le caractère fécond de la réflexion sur l’instrumentation pour penser les sciences sociales et l’action collective aujourd’hui.
Three-D Safari: Learning to Estimate Zebra Pose, Shape, and Texture From Images “In the Wild” (2019)

We present the first method to perform automatic 3D pose, shape and texture capture of animals from images acquired in-the-wild. In particular, we focus on the problem of capturing 3D information about Grevy's zebras from a collection of images. The Grevy's zebra is one of the most endangered species in Africa, with only a few thousand individuals left. Capturing the shape and pose of these animals can provide biologists and conservationists with information about animal health and behavior. In contrast to research on human pose, shape and texture estimation, training data for endangered species is limited, the animals are in complex natural scenes with occlusion, they are naturally camouflaged, travel in herds, and look similar to each other. To overcome these challenges, we integrate the recent SMAL animal model into a network-based regression pipeline, which we train end-to-end on synthetically generated images with pose, shape, and background variation. Going beyond state-of-the-art methods for human shape and pose estimation, our method learns a shape space for zebras during training. Learning such a shape space from images using only a photometric loss is novel, and the approach can be used to learn shape in other settings with limited 3D supervision. Moreover, we couple 3D pose and shape prediction with the task of texture synthesis, obtaining a full texture map of the animal from a single image. We show that the predicted texture map allows a novel per-instance unsupervised optimization over the network features. This method, SMALST (SMAL with learned Shape and Texture) goes beyond previous work, which assumed manual keypoints and/or segmentation, to regress directly from pixels to 3D animal shape, pose and texture.
Honeypot-Based Cyber Deception Against Malicious Reconnaissance via Hypergame Theory (2022)

Malicious reconnaissance is a critical step for attackers to collect sufficient network knowledge and choose valuable targets for intrusion. Defensive deception (DD) is an essential strategy against threats by misleading attackers' observations and beliefs. Honeypots are widely used for cyber deception that aims to confuse attackers and waste their resources and efforts. Defenders may use low-interaction honeypots or high-interaction honeypots. In this paper, we consider a hybrid honeypot system that balances the use of the two levels of honeypot complexity, where high-interaction honeypots are more capable of deceiving skilled attackers than low-interaction honeypots. We present a two-player hypergame model that characterizes how a defender should deploy low and high-interaction honeypots to defend the network against malicious reconnaissance activities. We model the tradeoff of each player and characterize their best strategies within a hypergame framework that considers the imperfect knowledge of each player toward their opponent. Finally, our numerical results validate the effectiveness of the proposed honeypot system.
Ocular manifestations of systemic arterial hypertension (2006)

Hypertension is a major cause of cardiovascular disease and is also a risk factor for various ocular diseases. Hypertension exerts its effects on the retinal, choroidal and optic nerve circulations. In this article, the various ocular manifestations of hypertension are reviewed. Retinal microangiopathy is strongly associated with blood pressure and risk of cardiovascular diseases, including stroke, cognitive decline and heart disease. Higher blood pressure is an important risk factor for the development and progression of diabetic retinopathy and has also been implicated in the pathogenesis of retinal vein occlusion, retinal artery occlusion, retinal arteriolar emboli and macroaneurysm. Hypertension has also been inconsistently linked with glaucoma and age-related macular degeneration. The management of patients with these ocular conditions should include appropriate assessment and management of hypertension.
The Status and Future of Acupuncture Clinical Research (2008)

On November 8-9, 2007, the Society for Acupuncture Research (SAR) hosted an international conference to mark the tenth anniversary of the landmark National Institutes of Health Consensus Development Conference on Acupuncture. More than 300 acupuncture researchers, practitioners, students, funding agency personnel, and health policy analysts from 20 countries attended the SAR meeting held at the University of Maryland School of Medicine, Baltimore, MD. This paper summarizes important invited lectures in the area of clinical research. Specifically, included are: a review of the recently conducted German trials and observational studies on low-back pain (LBP), gonarthrosis, migraine, and tension-type headache (the Acupuncture Research Trials and the German Acupuncture Trials, plus observational studies); a systematic review of acupuncture treatment for knee osteoarthritis (OA); and an overview of acupuncture trials in neurologic conditions, LBP, women's health, psychiatric disorders, and functional bowel disorders. A summary of the use of acupuncture in cancer care is also provided. Researchers involved in the German trials concluded that acupuncture is effective for treating chronic pain, but the correct selection of acupuncture points seems to play a limited role; no conclusions could be drawn about the placebo aspect of acupuncture, due to the design of the studies. Overall, when compared to sham, acupuncture did not show a benefit in treating knee OA or LBP, but acupuncture was better than a wait-list control and standard of care, respectively. In women's health, acupuncture has been found to be beneficial for patients with premenstrual syndrome, dysmenorrhea, several pregnancy-related conditions, and nausea in females who have cancers. Evidence on moxibustion for breech presentation, induction of labor, and reduction of menopausal symptoms is still inconclusive. In mental health, evidence for acupuncture's efficacy in treating neurologic and functional bowel disorder is still inconclusive. For chronic cancer-related problems such as pain, acupuncture may work well in stand-alone clinics; however, for acute or treatment-related symptoms, integration of acupuncture care into a busy and complex clinical environment is unlikely, unless compelling evidence of a considerable patient benefit can be established.

A new neutral dimeric gold(I) complex bearing the 1,2-bis[(2R,5R)-2,5-dimethylphospholanebenzene] [(R,R)-Me-Duphos] ligand has been synthesized which catalyzes the asymmetric hydrogenation of alkenes and imines under mild reaction conditions.
Beam and RB allocation in LTE uplink with opportunistic beamforming (2011)

Opportunistic beamforming is investigated in the context of multicell LTE uplink resource allocation. A scheduling algorithm based on beam and resource block (RB) allocation with opportunistic beamforming is presented. Beams are formed in a pseudorandom fashion thus allowing users to opportunistically benefit from the antenna gain and interference rejection capabilities. Results show that enhanced performance is obtained with opportunistic beamforming.

Thin-film hermeticity: A quantitative analysis of diamondlike carbon using variable angle spectroscopic ellipsometry (1988)

The purpose of this paper is twofold. First, we report on the successful application of variable angle spectroscopic ellipsometry to quantitative thin-film hermeticity evaluation. Secondly, it is shown that under a variety of film preparations and moisture introduction conditions water penetrates only a very thin diamondlike carbon (DLC) top surface-roughness region. Thus DLC is an excellent candidate for use as protective coatings in adverse chemical and aqueous environments.

Nanocomposites: Hybrid Organic–Inorganic Colloidal Composite ‘Sponges’ via Internal Crosslinking (Small 11/2015) (2015)

A generalized approach to form hybrid organic–inorganic nanocomposite microparticles via the structural reorganization of Pickering emulsion templates is described by V. M. Rotello and co-workers on page 1302. Hydrophilic nanoparticles assembled at the oil/water interface react with a hydrophobic polymer, pulling the particles into the oil core. The combined self-assembly and in-situ covalent conjugation strategy provides a facile method to generate robust porous nanocomposites with excellent stability and high capacity.
A wavelet transform-based capacity curve estimation approach using seismic response data (2018)

This paper presents an automated method for derivation of capacity curve from measured structural acceleration response. Based on the decomposition by wavelet transform method, the structural behavior is directly evaluated in the form of a capacity curve of the predominant response, as a relationship between the spectral force and spectral displacement. It enables the user to judge the performance of the building quickly after an earthquake. The feasibility of the proposed method is demonstrated through numerical simulations, full-scale shaking-table tests, and actual response of a steel tower during 2016 Fukushima earthquake.
The Influence of Promoter on Ni(15)/La(5)/<I>γ</I>-Al<SUB>2</SUB>O<SUB>3</SUB> Catalyst in CO<SUB>2</SUB>-Steam Reforming of Methane to Syngas at High Pressure (2014)

Catalysts were investigated with respect to catalytic activity and coke formation in combined steam and carbon dioxide reforming of methane to develop a highly active and stable catalyst for gas to liquid processes. Ni/La-X/Al2O3 (X = Co, Ce, Mo) catalysts were prepared by an impregnation method. The combined steam and carbon dioxide reforming of methane reaction were studied as a function of high pressure (20 bar) in a fixed bed reactor system. X-ray diffraction, BET surface area, and H2-temperature programmed reduction were used to observe the characteristics of the prepared catalysts. Coke formation of used catalysts was examined by scanning electron microscopy, transmission electron microscopy and the coke amount of used catalysts was measured by thermo gravimetric analysis. Catalysts with smaller particle size had a higher temperature of reduction, which had a positive effect on catalytic activity. The improvement in active site rise and dispersion and the lowest metal crystal size had an effect on catalyst activity. As a result, the Ni/La-Co/Al2O3 catalyst showed the highest activity at a reaction temperature of 800 degrees C and a reaction pressure of 20 bar.

Long-term chronic baroreflex activation (2015)

BAT provides long-term chronic reductions in sympathetic activity and utilization of hospital resources in patients with HFrEF. General clinical presentation, quality of life and functional capacity are likewise improved and maintained. The temporal association of BAT with sympathetic drive diminution and improvement in objective clinical measures suggests a cause-and-effect relationship that will be verified in future randomized controlled trials of outcome.
Case report of a clinically indolent but morphologically high‐grade cutaneous mast cell tumor in an adult: Atypical cutaneous mastocytoma or mast cell sarcoma? (2021)

We present a case of an adult male with a solitary mast cell tumor of the skin with unusual nuclear pleomorphism and mitotic activity. The tumor was excised, recurred within 2 years, was reexcised after 4 years and did not recur >6 years after diagnosis. The tumor showed progressive cytonuclear atypia and a high mitotic and proliferation rate by Ki67-staining from the onset. No KIT mutations were identified in the tumor and bone marrow. Serum tryptase levels and a bone marrow aspirate and trephine biopsy were normal. Although the histomorphology of the skin tumor was consistent with mast cell sarcoma, the clinical behavior without systemic progression argued against this diagnosis. The tumor was finally considered as atypical mastocytoma, borderline to mast cell sarcoma. Currently, the patient is in close follow-up and still in complete remission.
Recursive Descriptions of Decoding Algorithms and Hardware Architectures for Polar Codes (2012)

Polar codes are recursive general concatenated codes. This property motivates a recursive formalization of the known decoding algorithms: Successive Cancellation, Successive Cancellation with Lists and Belief Propagation. This description allows an easy development of the first two algorithms for arbitrary polarizing kernels. Hardware architectures for these decoding algorithms are also described in a recursive way, both for Arikan's standard polar codes and for arbitrary polarizing kernels.

Demo: Real-time depth extraction and viewpoint interpolation on FPGA (2011)

In this demo, we demonstrate a real-time viewpoint interpolation application on FPGA. Viewpoint interpolation is the process of synthesizing plausible in-between views - so-called virtual camera views - from a couple of surrounding fixed camera views. Stereo matching is used to extract depth information, by computing a disparity map from a pair of input images. With the depth information, virtual views at any points between the two cameras are computed through view interpolation. To make viewpoint interpolation possible for low/moderate-power consumer applications, a further quality/complexity tradeoff study is required to conciliate algorithmic quality to architectural performance. In essence, the inter-dependencies between the different algorithmic steps in the processing chain are thoroughly analyzed, aiming at an overall quality-performance model that pinpoints which algorithmic functionalities can be simplified with minor (preferably no) global input-output quality degradation, while maximally reducing their implementation complexity w.r.t. arithmetic and line buffer requirements. Compared to state-of-the-art CPU and GPU platforms running at several GHz clock speed, our low-power 65 MHz FPGA implementation achieves speedups with one order of magnitude over state-of-the-art, without impeding on the visual quality, reaching over 60 frames per second high-definition (1024×768) high-quality, 64-disparity search range stereo matching and enabling viewpoint interpolation in low-power, embedded applications.
Intramolecular chloride shift polymerization by cationic mechanism. Polymerization of 3‐chloro‐3‐methyl‐1‐butene and the effect of temperature on polymer structure (1966)

Abstract The cationic polymerization of 3‐chloro‐3‐methyl‐1‐butene was investigated in the temperature range from −30° to −130°C. The structure of the polymer was characterized by NMR spectroscopy and was found to be a mixture of about equal portions of magnified image repeating units. Changing the temperature from −30° to −130°C. affects only slightly the respective amounts of these structures. No evidence for methide shift polymerization was found. These results are discussed in terms of an earlier proposed mechanism.
