Depth from Small Motion using Rank-1 Initialization (2019)

Depth from Small Motion (DfSM) (Ha et al., 2016) is particularly interesting for commercial handheld devices because it allows the possibility to get depth information with minimal user effort and cooperation. Due to speed and memory issue on these devices, the self calibration optimization of the method using Bundle Adjustment (BA) need as little as 10-15 images. Therefore, the optimization tends to take many iterations to converge or may not converge at all in some cases. This work propose a robust initialization for the bundle adjustment using the rank-1 factorization method (Tomasi and Kanade, 1992), (Aguiar and Moura, 1999a). We create a constraint matrix that is rank-1 in a noiseless situation, then use SVD to compute the inverse depth values and the camera motion. We only need about quarter fraction of the bundle adjustment iteration to converge. We also propose grided feature extraction technique so that only important and small features are tracked all over the image frames. This also ensure speedup in the full execution time on the mobile device. For the experiments, we have documented the execution time with the proposed Rank-1 initialization on two mobile device platforms using optimized accelerations with CPU-GPU co-processing. The combination of Rank 1-BA generates more robust depth-map and is significantly faster than using BA alone.

Role of mTOR Signaling Cascade in Epidermal Morphogenesis and Skin Barrier Formation (2022)

The skin epidermis, with its capacity for lifelong self-renewal and rapid repairing response upon injury, must maintain an active status in metabolism. Mechanistic target of rapamycin (mTOR) signaling is a central controller of cellular growth and metabolism that coordinates diverse physiological and pathological processes in a variety of tissues and organs. Recent evidence with genetic mouse models highlights an essential role of the mTOR signaling network in epidermal morphogenesis and barrier formation. In this review, we focus on the recent advances in understanding how mTOR signaling networks, including upstream inputs, kinases and downstream effectors, regulate epidermal morphogenesis and skin barrier formation. Understanding the details of the metabolic signaling will be critical for the development of novel pharmacological approaches to promote skin barrier regeneration and to treat epidermal barrier defect-associated diseases.
UV photodecomposition of zinc acetate for the growth of ZnO nanowires (2015)

The thermal annealing of zinc precursors to form suitable seed layers for the growth of ZnO nanowires is common. However, the process is relatively long and involves high temperatures which limit substrate choice. In this study the use of a low temperature, ultra-violet (UV) exposure is demonstrated for photodecomposition of zinc acetate precursors to form suitable seed layers. Comparisons are made between ZnO nanowire growth performed on seed layers produced through thermal annealing and exposure to UV. The dependence of growth density and nanowire diameter on UV exposure time is investigated. Growth quality is confirmed with energy dispersive x-ray (EDX) and x-ray diffraction analyses. The chemical composition of the exposed layers is investigated with EDX and x-ray photoelectron spectroscopy (XPS). Atomic force microscopy (AFM) is utilized to investigate morphological changes with respect to UV exposure. The diameter and density of the resultant growth was found to be strongly dependent on the UV exposure time. UV exposure times of only 25-30 s led to maximum density of growth and minimum diameter, significantly faster than thermal annealing. EDX, XPS and AFM analyses of the seed layers confirmed decomposition of the zinc precursor and morphological changes which influenced the growth.
A Comprehensive Review of Brain Connectomics and Imaging to Improve Deep Brain Stimulation Outcomes (2020)

DBS is an effective neuromodulatory therapy that has been applied in various conditions, including PD, essential tremor, dystonia, Tourette syndrome, and other movement disorders. There have also been recent examples of applications in epilepsy, chronic pain, and neuropsychiatric conditions. Innovations in neuroimaging technology have been driving connectomics, an emerging whole-brain network approach to neuroscience. Two rising techniques are functional connectivity profiling and structural connectivity profiling. Functional connectivity profiling explores the operational relationships between multiple regions of the brain with respect to time and stimuli. Structural connectivity profiling approximates physical connections between different brain regions through reconstruction of axonal fibers. Through these techniques, complex relationships can be described in various disease states, such as PD, as well as in response to therapy, such as DBS. These advances have expanded our understanding of human brain function and have provided a partial in vivo glimpse into the underlying brain circuits underpinning movement and other disorders. This comprehensive review will highlight the contemporary concepts in brain connectivity as applied to DBS, as well as introduce emerging considerations in movement disorders. © 2020 International Parkinson and Movement Disorder Society.
Bio-efficacy of plants extracts against Alternaria carthmi caused Alternaria Leaf spot of safflower (2019)

Safflower (Carthomus tinctorius L) is most important oilseed crop and several bacteria, fungi and virus infect it and cause diseases. Alternaria Leaf spot of Safflower is very worst disease and distributed worldwide in all safflower growing countries. This disease is caused by Alternaria carthmi and pathogen affect the oil content of safflower and yield. Experiment carried out on Bio-efficacy of plant extracts against Alternaria carthmi caused Alternaria Leaf spot of Safflower. Five plant extracts viz, Azadirachta indica, Capsicum annum, Allium sativum (bulbs), Eucalyptus globulus, Mentha arvensis and mixture of all plant extract each of them at two concentration 15% and 25% were evaluated against Alternaria carthmi. Mixture of all plant extracts and garlic (bulbs) extracts were found highly effective against pathogen at both 15% and 25% concentration and mycelial inhibition was recorded 62.16% at 25% concentration. Another two plant extracts Neem and chilli was also found to be effective against pathogen and both showed 52.15% inhibition at 25% concentration. There are different plant extracts are available in nature. However, some plant extracts are highly effective and some plant extracts are not effective against pathogen. Therefore, this investigation will be helpful to the farmers for selection of suitable plant extracts, used as a control of Alternaria Leaf spot of Safflower.
Inspiring blind high school students to pursue computer science with instant messaging chatbots (2008)

Blind students are an underrepresented group in computer science. In this paper, we describe our experience preparing and leading the computer science track at the National Federation of the Blind Youth Slam. As part of this workshop, fifteen blind high school students created and personalized instant messaging chatbots, a project designed to be completely accessible to blind students. Chatbots enable students to infuse their own personalities into a socially-oriented program that incorporates ideas from artificial intelligence, natural language processing, and web services. We first outline the chatbots project and curriculum, which has wide appeal for all students, and then offer general design principles used to create it that can help ensure the accessibility of future projects. Students created their chatbots using a real programming language and were guided by both blind and sighted mentors. By programming from the start in a supportive environment, our students will gain the confidence to persevere in computer science in the future.
Encapsulation of Luminous Recombinant E. coli in Sol–Gel Silicate Films (2001)

Long-term immobilization of recombinant luminous bacteria in transparent sol–gel derived silicate films is reported by these authors. Aspects such as the light response of the encapsulated bacteria after exposure to various luminescence inducers at different doses and the evolution of luminescence during the gelation process are examined. Based on these experiments it is concluded that the recombinant bacteria has a high biocompatibility with sol–gel derived silicate gels. Sensing of encapsulation-induced physiological stress will help devise synthesis procedures that will minimize cell inactivation during immobilization.
[Acute implantation technique of the ellipsoid heart for clinical left ventricular assistance (author's transl)]. (1980)

The results of the first clinical trials of left ventricular assist devices are not encouraging. The only indication at present is in patients with cardiac failure after cardiac operations. The acute type of ellipsoid heart described in this paper-displays a canulation technique where the inflow canula inserted in the left ventricular cavity via the left atrium and the outflow canula is directly connected to the aortic canula of the cardiopulmonary bypass. The haemodynamic response shows the efficacy of this system. The circulation can be maintained in severe cardiac failure, as well as in ventricular fibrillation and cardiac arrest. On the basis of data obtained in experiments on 7 female calves this system is considered worthy of clinical trial.
Refractory peptic ulcers. (1992)

Ulcers that do not heal after 8 weeks of treatment with standard-dose regimens of antiulcer drugs are considered refractory. Incidences of duodenal and gastric ulcers refractory to H2-receptor antagonists are 9% and 20%, respectively. When treated with a single daily dose of omeprazole 20 mg, duodenal ulcers have a refractory incidence of 3% and gastric ulcers, 11%. Omeprazole's benefit may result from its potent gastric antisecretory action. Acid hypersecretion is an important pathophysiologic factor associated with refractoriness to H2 antagonists. Some patients with refractory ulcer, however, have a normal pharmacologic response of decreasing intragastric acidity following administration of H2 antagonists. Two possible mechanisms may explain refractoriness in such cases: the relative preservation of daytime acidity, which is the usual pharmacologic response to standard doses of H2 antagonists, and excessive impairment of mucosal defense. The first possibility is consistent with the results that increased doses of H2 antagonists or more potent antisecretory drugs such as omeprazole do heal a subgroup of ulcers refractory to H2 antagonists. The second possibility is supported by reports that drugs that mainly enhance mucosal defense, such as misoprostol, sucralfate, and bismuth compounds, also effectively heal refractory ulcers, and that gastrointestinal prostaglandin levels are extremely low in the mucosa of such patients. Other reasons for refractoriness to omeprazole treatment include gastric hyperacidity and impaired gastric emptying that may disturb drug absorption. Infection with Helicobacter pylori might, to some extent, be involved in refractoriness to potent antisecretory drugs. Single daily doses of omeprazole 40 mg seem superior to omeprazole 20 mg or increased doses of H2 antagonists for maintenance therapy of H2 antagonist-refractory ulcers.(ABSTRACT TRUNCATED AT 250 WORDS)
Contribution of Polybrominated Dibenzo-p-dioxins and Dibenzofurans (PBDD/Fs) to the Toxic Equivalency of Dioxin-like Compounds in Archived Biosolids from the U.S. EPA’s 2001 National Sewage Sludge Survey (2014)

The World Health Organization recently proposed the inclusion of brominated congeners in addition to chlorinated congeners when computing the toxic equivalency (TEQ) of dioxin-like compounds (DLCs) in assessments of human health risks. In the present study, 12 polybrominated dibenzo-p-dioxins and furans (PBDD/Fs) were analyzed by gas chromatography/high resolution mass spectrometry in the composited, archived biosolids that were collected in 32 U.S. states and the District of Columbia from 94 wastewater treatment plants by the United States Environmental Protection Agency in its 2001 national sewage sludge survey. Two PBDDs and five PBDFs were detected in the biosolids composites at varying frequencies (40-100%) with a total mean concentration of 10,000 ng/kg dry weight (range: 630-42,800), of which 1,2,3,4,6,7,8-hepta-BDF constituted about 95% by mass. Relative to commercial polybrominated diphenyl ether (PBDE) formulations, the ratio of PBDD/Fs to PBDEs in biosolids was 55-times higher (∼ 0.002% vs ∼ 0.11%), which indicates potential PBDE transformation or possibly additional sources of PBDD/Fs in the environment. The TEQ contribution of PBDD/Fs was estimated at 162 ng/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) (range: 15-672), which is equivalent to 75% (range: 12-96%) of the total TEQ in biosolids. The TEQ of DLCs released annually to U.S. soils as a result of the land application of biosolids was estimated at 720 g (range: 530-1600 g). Among all known DLCs determined in biosolids, brominated analogs contributed 370% more TEQ than did chlorinated congeners, which indicates the need to include brominated DLCs in the exposure and risk assessment of land-applied biosolids.

A data-mining approach for optimizing performance of an incremental crawler (2004)

Crawlers visit the Web to maintain a local repository of Web pages up to date. We introduce another perspective to build an effective incremental crawler. Based on previous work in this field, we study how we can improve the performance of a crawler using data-mining. The information collected from the users can help the crawler to know which are the popular pages and to revisit them as soon as possible.
Energy-Based Evaluation and Remediation of Liquefiable Soils (2004)

The states-of-practice for performing remedial ground densification and evaluating earthquake liquefaction potential of loose saturated sands have evolved relatively independent of each other. This is in spite of the fact that the induction of liquefaction is typically requisite for remedial ground densification of sands. Simple calculations are presented herein for estimating the mechanical energy required to densify a unit volume of clean, loose sand using deep dynamic compaction, vibro-compaction, and explosive compaction. These computed energies are compared with that required to induce liquefaction during an earthquake using the Green-Mitchell energy based liquefaction evaluation procedure. The comparison highlights the importance of the efficiency of the method in which the energy is imparted to the soil and the importance of the mode of dissipation of the imparted energy (e.g., possible modes of energy dissipation/expenditure include: breaking down of initial soil structure, ramming soil particles into denser packing, and radiating away from the treatment zone). Additionally, the comparison lays the preliminary groundwork for incorporating the vast knowledge base gained from fundamental studies on earthquake induced liquefaction into the design procedures of remedial ground densification techniques.

Controlling mode instabilities by dynamic mode excitation with an acousto-optic deflector (2013)

We demonstrate an approach to actively stabilize the beam profile of a fiber amplifier above the mode instability threshold. Both the beam quality and the pointing stability are significantly increased at power levels of up to three times the mode instabilities threshold. The physical working principle is discussed at the light of the recently published theoretical explanations of mode instabilities.
Molecular cytogenetic mapping of the human melanoma antigen (MAGE) gene family to chromosome region Xq27-qter: implications for MAGE immunotherapy. (1994)

We have defined the chromosomal location of the human MAGE (melanoma antigen) gene family by polymerase chain reaction amplification of several segments of the MAGE genes from somatic cell hybrids containing well-defined groups of human chromosomes and hybrids containing human derivative chromosomes. The data show that the three known MAGE family members (MAGEs -1, -2, & -3) are syntenic and map to the human X chromosome region q27-qter. Because males and females are hemizygous for most X-linked genes, the frequency of antigen-loss variants for the MAGE system is expected to be greater in comparison to antigens encoded by somatic chromosomes. In this regard, we believe that patients enrolled in MAGE-specific immunotherapy trials should be carefully monitored for the presence of MAGE antigen-loss variants.
Advances in pain management (2014)

Over the past 30 years there have been many improvements in implant fixation, correction of deformity, improved polyethylene wear, and survival after knee replacement. The work over the last decade has focused on less invasive surgical techniques, multimodal pain management protocols, more rapid functional recovery and reduced length of stay, aiming to minimise the side effects of treatment while maintaining function and implant durability. When combined and standardised these pre-, intra- and post-operative factors have now facilitated outpatient knee replacement procedures for unicompartmental replacement, patella femoral arthroplasty and total knee replacement (TKR). We have found liposomal bupivacaine, with potential for longer therapeutic action, to be a helpful adjunct and describe our current pain management program. The next step in our multimodal program is to improve the duration of patient satisfaction and reduce cost and length of stay after TKR.
A survey on Adversarial Recommender Systems: from Attack/Defense strategies to Generative Adversarial Networks (2020)

Latent-factor models (LFM) based on collaborative filtering (CF), such as matrix factorization (MF) and deep CF methods, are widely used in modern recommender systems (RS) due to their excellent performance and recommendation accuracy. However, success has been accompanied with a major new arising challenge: many applications of machine learning (ML) are adversarial in nature. In recent years, it has been shown that these methods are vulnerable to adversarial examples, i.e., subtle but non-random perturbations designed to force recommendation models to produce erroneous outputs. The goal of this survey is two-fold: (i) to present recent advances on adversarial machine learning (AML) for the security of RS (i.e., attacking and defense recommendation models), (ii) to show another successful application of AML in generative adversarial networks (GANs) for generative applications, thanks to their ability for learning (high-dimensional) data distributions. In this survey, we provide an exhaustive literature review of 74 articles published in major RS and ML journals and conferences. This review serves as a reference for the RS community, working on the security of RS or on generative models using GANs to improve their quality.

L-Asparaginase Isolated from Phaseolus vulgaris Seeds Exhibited Potent Anti-Acute Lymphoblastic Leukemia Effects In-Vitro and Low Immunogenic Properties In-Vivo (2016)

<i>Escherichia coli</i>-derived L-asparaginases have been used in the treatment of acute lymphoblastic leukemia (ALL), however, clinical hypersensitivity reactions and silent inactivation due to antibodies against <i>E. coli</i>-asparaginase, lead to inactivation of these preparations in most cases.Therefore, this study was aimed to investigate the cytotoxicity and antitumor effects ofa novel L-asparaginaseenzyme, isolated from <i>Phaseolus vulgaris</i> seeds (P-Asp) on the ALL cell line (Jurkat). The immunogenicity of the enzyme was also evaluated in-vivo and results were compared to commercially available enzymes of microbial sources. The data demonstrated that P-Asp has an enhanced anti-proliferative effect on ALL cells as detected by the WST-8 cell viability assay kit. Cells treated with P-Asp also exhibited a higher degree of early apoptosis compared with asparaginase from <i>Escherichia coli</i> (L-Asp) or its pegylated form Pegasparagas (PEG-ASP) that induced higher rates of late apoptosis and necrosis as detected by an Annexin V/Propidium iodide binding assay. In-vivo experiments indicated that mice treated with P-Asp had less distinct allergenic responses than other bacterial enzyme preparations as indicated by lower serum concentrations of IgG, IgE, IgM and mMCP-1 compared with other treated groups. In conclusion, P-Asp can be considered as a promising candidate for use in the treatment of ALL.
Integrated dry NO{sub x}/SO{sub 2} emissions control system performance summary (1997)

The Integrated Dry NO{sub x}/SO{sub 2} Emissions Control System was installed at Public Service Company of Colorado`s Arapahoe 4 generating station in 1992 in cooperation with the US Department of Energy (DOE) and the Electric Power Research Institute (EPRI). This full-scale 100 MWe demonstration combines low-NO{sub x} burners, overfire, air, and selective non-catalytic reduction (SNCR) for NO{sub x} control and dry sorbent injection (DSI) with or without humidification for SO{sub 2} control. Operation and testing of the Integrated Dry NO{sub x}/SO{sub 2} Emissions Control System began in August 1992 and will continue through 1996. Results of the NO{sub x} control technologies show that the original system goal of 70% NO{sub x} removal has been easily met and the combustion and SNCR systems can achieve NO{sub x} removals of up to 80% at full load. Duct injection of commercial calcium hydroxide has achieved a maximum SO{sub 2} removal of nearly 40% while humidifying the flue gas to a 20 F approach to saturation. Sodium-based dry sorbent injection has provided SO{sub 2} removal of over 70% without the occurrence of a visible NO{sub 2} plume. Recent test work has improved SNCR performance at low loads and has demonstrated that combined dry sodium injection and SNCR yields both lower NO{sub 2} levels and NH{sub 3} slip than either technology alone.
