Effective Video Annotation by Mining Visual Features and Speech Features (2007)

In the area of multimedia processing, a number of studies have been devoted to narrowing the gap between multimedia content and human sense. In fact, multimedia understanding is a difficult and challenging task even using machine-learning techniques. To deal with this challenge, in this paper, we propose an innovative method that employs data mining techniques and content-based paradigm to conceptualize videos. Mainly, our proposed method puts the focus on: (I) Construction of prediction models, namely speech-association model Model <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Sass</sub> and visual-statistical model Model <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CRM</sub> , and (2) Fusion of prediction models to annotate unknown videos automatically. Without additional manual cost, discovered speech-association patterns can show the implicit relationships among the sequential images. On the other hand, visual features can atone for the inadequacy of speech-association patterns. Empirical evaluations reveal that our approach makes, on the average, the promising results than other methods for annotating videos.
An alternative use of power quality information - Load signature studies &amp; applications (2012)

Electrical appliances have distinct consumption patterns of which can be interpreted as signatures and used for various applications. Based on traditional power quality monitoring techniques, coupled with optimization algorithms and innovative pattern recognition methods and stochastic simulation tools, we are going to demonstrate in this paper how we defined different load signatures systematically, structured a disaggregation framework to identify and track individual appliances, assembled different Monte-Carlo simulators for testing purposes and proposed some innovative applications such as smart metering and equipment health monitoring using different load signatures.
Association between In Utero arsenic exposure, placental gene expression, and infant birth weight: a US birth cohort study (2013)

We identified the expression of AQP9 as a potential fetal biomarker for arsenic exposure. Further, we identified a positive association between the placental expression of phospholipase ENPP2 and infant birth weight. These findings suggest a path by which arsenic may affect birth outcomes.
The complement membrane attack complex triggers intracellular Ca2+ fluxes leading to NLRP3 inflammasome activation (2013)

The membrane attack complex of complement (MAC), apart from its classical role of lysing cells, can also trigger a range of non-lethal effects on cells, acting as a drive to inflammation. In the present study, we chose to investigate these non-lethal effects on inflammasome activation. We found that, following sublytic MAC attack, there is increased cytosolic Ca(2+) concentration, at least partly through Ca(2+) release from the endoplasmic reticulum lumen via the inositol 1,4,5-triphosphate receptor (IP3R) and ryanodine receptor (RyR) channels. This increase in intracellular Ca(2+) concentration leads to Ca(2+) accumulation in the mitochondrial matrix via the 'mitochondrial calcium uniporter' (MCU), and loss of mitochondrial transmembrane potential, triggering NLRP3 inflammasome activation and IL-1β release. NLRP3 co-localises with the mitochondria, probably sensing the increase in calcium and the resultant mitochondrial dysfunction, leading to caspase activation and apoptosis. This is the first study that links non-lethal effects of sublytic MAC attack with inflammasome activation and provides a mechanism by which sublytic MAC can drive inflammation and apoptosis.
End-to-End Conditional GAN-based Architectures for Image Colourisation (2019)

In this work recent advances in conditional adversarial networks are investigated to develop an end-to-end architecture based on Convolutional Neural Networks (CNNs) to directly map realistic colours to an input greyscale image. Observing that existing colourisation methods sometimes exhibit a lack of colourfulness, this paper proposes a method to improve colourisation results. In particular, the method uses Generative Adversarial Neural Networks (GANs) and focuses on improvement of training stability to enable better generalisation in large multi-class image datasets. Additionally, the integration of instance and batch normalisation layers in both generator and discriminator is introduced to the popular U-Net architecture, boosting the network capabilities to generalise the style changes of the content. The method has been tested using the ILSVRC 2012 dataset, achieving improved automatic colourisation results compared to other methods based on GANs.
[Effect of calcitonin gene-related peptide and vasoactive intestinal polypeptide on delayed cerebral vasospasm studied after experimental subarachnoid hemorrhage in rabbits]. (1994)

Calcitonin gene-related peptide (CGRP) and vasoactive intestinal polypeptide (VIP) are intrinsic vasodilatory substances contained in perivascular nerve fibers innervating large intracranial arteries. Effects of these substances on delayed cerebral vasospasm were examined using a rabbit model of experimental subarachnoid hemorrhage (SAH). Sixty-one anesthetized rabbits received intrathecal fresh arterial blood on day-1 and intrathecal administration of different doses of CGRP, VIP or distilled water on day-4. Prior to the treatment, caliber of the spastic basilar artery was 73.4 +/- 0.9% of pre-SAH values. Serial angiograms after treatment demonstrated that 10(-10)mol/kg of CGRP dilated the spastic artery to 117.1% of pre-SAH levels and that dilatory effect of CGRP continued up to 6 hours after treatment. VIP injection also brought arterial dilatation up to 114.9% of pre-SAH levels, although the duration of the effect was less than 3 hours. Intrathecal administration of CGRP or VIP showed no adverse effect on the systemic and neurological state of the animals. These results indicate that intrathecal CGRP and VIP have therapeutic potential in treating delayed cerebral vasospasm after subarachnoid hemorrhage. Further investigations are expected to extend the effect of CGRP and VIP.
Photosensitizer-Loaded Gold Vesicles with Strong Plasmonic Coupling Effect for Imaging-Guided Photothermal/Photodynamic Therapy (2013)

A multifunctional theranostic platform based on photosensitizer-loaded plasmonic vesicular assemblies of gold nanoparticles (GNPs) is developed for effective cancer imaging and treatment. The gold vesicles (GVs) composed of a monolayer of assembled GNPs show strong absorbance in the near-infrared (NIR) range of 650-800 nm, as a result of the plasmonic coupling effect between neighboring GNPs in the vesicular membranes. The strong NIR absorption and the capability of encapsulating photosensitizer Ce6 in GVs enable trimodality NIR fluorescence/thermal/photoacoustic imaging-guided synergistic photothermal/photodynamic therapy (PTT/PDT) with improved efficacy. The Ce6-loaded GVs (GV-Ce6) have the following characteristics: (i) high Ce6 loading efficiency (up to ~18.4 wt %; (ii) enhanced cellular uptake efficiency of Ce6; (iii) simultaneous trimodality NIR fluorescence/thermal/photoacoustic imaging; (iv) synergistic PTT/PDT treatment with improved efficacy using single wavelength continuous wave laser irradiation.

The InterMezzo File System (1999)

Is it possible to implement a distributed file system, retaining some of the advanced protocol features of systems like Coda, while getting an implementation that is an order of magnitude simpler? We claim the answer is &quot;yes&quot;, and InterMezzo is well on its way towards being a prototype of such a system. The key design decisions were to exploit local file systems as server storage and as a client cache and make the kernel file system driver a wrapper around a local file system. We use a rich, high level language and work with asynchronous completion instead of threads. Finally, we rely on existing infrastructure, such as TCP. This is in contrast with systems like Coda and AFS, which implement their entire infrastructure from the ground up, in C. This paper will describe the design and implementation decisions used in our prototype.
Macrophage differentiation in atherosclerosis. An in situ immunohistochemical analysis in humans. (1992)

The differentiation of macrophages present in diffuse intimal thickening, fatty streaks, and atheromatous plaques, was analyzed with immunohistochemical methods, using segments of aorta, coronary, and carotid arteries obtained at autopsy. Various differentiation antigens were studied with the monoclonal antibodies anti-HLA-DR, EBM-11, Leu M3, OKM1, and OKM5. Adjacent sections were stained for lipids (oil red O) and lysosomal activity (acid phosphatase). Almost all macrophages identified with the pan-macrophage antibody EBM-11, also stained with the anti-HLA-DR antibody. Diffuse intimal thickening showed a predominance of Leu M3+ cells; fatty streaks also showed OKM1+ and OKM5+ macrophages. Classical atheromatous plaques showed a gradual shift in phenotypic expression towards the center of the lesion. Cells in the superficial layers were positive only with Leu M3, deeper localized cells showed double expression of Leu M3 and OKM1 or double expression of OKM1 and OKM5. Cells that were localized adjacent to the atheromatous debris stained only with OKM5. The phenotypic changes occurred in parallel with an increase in both fat uptake and lysosomal activity of the macrophages. This shift in phenotypic expression suggests a process of differentiation and maturation of the macrophages involved. The results indicate that macrophages within the arterial intima are activated and mature towards cells that express receptors for adhesion proteins and complement during the development of atherosclerotic plaques. This may imply that the macrophages involved in lipid metabolism also have a potential to act as effector cells in a chronic inflammatory process, and thus, may contribute to the progression of an atherosclerotic plaque. Functional studies of macrophage subpopulations are needed to verify this hypothesis.
A Blockchain Platform for User Data Sharing Ensuring User Control and Incentives (2020)

We propose a new platform for user modelling with blockchains that allows users to share data without losing control and ownership of it and applied it to the domain of travel booking. Our platform provides solution to three important problems: ensuring privacy and user control, and incentives for sharing. It tracks who shared what, with whom, when, by what means and for what purposes in a verifiable fashion. The paper presents a case study of applying the framework for a hotel reservation system as one of the enterprise nodes of Multichain which collects users’ profile data and allows users to receive rewards while sharing their data with other travel service providers according to their privacy preferences expressed in smart contracts. The user data from the repository is converted into an open data format and shared via stream in the blockchain so that other nodes can efficiently process and use the data. The smart contract verifies and executes the agreed terms of use of the data and transfers digital tokens as a reward to the user. The smart contract imposes double deposit collateral to ensure that all participants act honestly. The paper also presents a performance evaluation of the platform by analyzing latency and memory consumption with selected three test-scenarios and measuring the transaction cost for smart contracts deployment. The results show that the node responded quickly in all our cases with a befitting transaction cost.
Impact of oxygen supply during growth on the electrical properties of crystalline Gd2O3 thin films on Si(001) (2006)

We investigated the influence of additional oxygen supply and temperature during the growth of thin Gd2O3 layers on Si(001) with molecular beam epitaxy. Additional oxygen supply during growth improves the dielectric properties significantly; however, too high oxygen partial pressures lead to an increase in the lower permittivity interfacial layer thickness. The growth temperature mainly influences the dielectric gate stack properties due to changes of the Gd2O3∕Si interface structure. Optimized conditions (600°C and pO2=5×10−7mbar) were found to achieve equivalent oxide thickness values below 1nm accompanied by leakage current densities below 1mA∕cm2 at 1V.
Colloidal synthesis of lead-free all-inorganic cesium bismuth bromide perovskite nanoplatelets (2018)

Lead halide two-dimensional (2D) nanoplatelets (NPLs) have attracted intense interest due to their unique optoelectronic properties.
Contribution of Interstitial Diffusion in Drug Absorption from Perfused Rabbit Muscle: Effect of Hyaluronidase on Absorption. (1992)

[3H]Water and [14C]inulin were injected into perfused rabbit muscle with or without hyaluronidase (300 units/ml) and their absorption into venous effluent from muscle was determined. Hyaluronidase accelerated the absorption of both compounds but the enhancement of [14C]inulin was much larger than that for [3H]water. The pharmacokinetic analysis of venous appearance curves based on a physiological diffusion model elucidated that interstitial diffusion of [14C]inulin was remarkably increased by hyaluronidase treatment, suggesting the existence of steric hindrance for it by the polysaccharide network under normal conditions. Enhancement of [3H]water diffusion was also detected although enhancement ratio was about one-half of that of [14C]inulin. Mean time necessary for each process was calculated using the statistical moment concepts. The results suggested predominant contribution of the interstitial diffusion process and secondary and little contribution of local perfusion flow and permeation process across the capillary wall, respectively, in total absorption of [14C]inulin. Effect of hyaluronidase on transcapillary movement of [14C]inulin was studied using an in vitro diffusion experiment with cultured endothelial cell monolayer and no enhancing effect was shown on [14C]inulin transport across the cell monolayer. The contribution of the local perfusion flow, on the other hand, was shown to be almost equivalent to that of the diffusion process in the total absorption of [3H]water.
Medium-Chain Fatty Acids Improve Cognitive Function in Intensively Treated Type 1 Diabetic Patients and Support In Vitro Synaptic Transmission During Acute Hypoglycemia (2009)

Medium-chain triglyceride ingestion improves cognition without adversely affecting adrenergic or symptomatic responses to hypoglycemia in intensively treated type 1 diabetic subjects. Medium-chain triglycerides offer the therapeutic advantage of preserving brain function under hypoglycemic conditions without causing deleterious hyperglycemia.
Development and evaluation of a coculture technique for identification of anaerobic organisms (1984)

We investigated a method to reduce oxygen tension and produce anaerobic conditions conveniently by coculture with a nonfermentative organism. The biochemical reactions of 94 strains representing 41 different species were determined using prereduced media and gas chromatography according to standard methods. The standard reactions were compared with those obtained by preparing similar media, modified by containing no cysteine or resazurin, under aerobic conditions. Preincubation of the modified biochemical media with a standard suspension of a culture of Acinetobacter lwoffi provided reducing conditions. In 1,449 individual tests using 22 different biochemicals, 1,349 (93%) of the reactions agreed. Only two misidentifications resulted when using the modified media, one each at the species and genus levels. Two strains of Actinomyces odontolyticus failed to grow in coculture.
Automatic performance model synthesis from hardware verification models (2011)

Performance models are typically written by hand for a new model or assembled piece-meal from the prior simulation code of an old model. In either case, many man-months of work may be required to write the new model and validate design details against a prior or current design. In reality, the majority of information about the performance of the design already exists in the design structure of either the old hardware model or the new model or both. To harvest this information and eliminate the significant duplicate coding and validation efforts, we propose that a performance model be automatically synthesized from a prior or current hardware design using a bottom-up, design-oriented approach. We demarcate the performance-critical boundaries of the design and perform backward-trace cone analysis to identify logic to include in the performance model. We then abstract specific components for design changes and expend modeling effort only on the few functions relevant to a particular design study. Engineering effort then becomes focused on workload selection and quality, defining and projecting new designs, and assessing design tradeoffs and sensitivities - the small set of tasks with the highest potential to improve design performance.
Reflection Angle-Domain Pseudoextended Least-Squares Reverse Time Migration Using Hybrid Regularization (2020)

Angle-domain common image gathers (ADCIGs) describe the reflectivity variation over reflection angles which are important for seismic exploration. The ADCIGs could be obtained using reverse time migration (RTM). However, because of the limitation of seismic frequency band and acquisition geometry, RTM produces the ADCIGs with low fidelity. We propose a reflection angle-domain pseudoextended least-squares RTM method to improve the quality of the ADCIGs in which the Poynting vector is used to efficiently calculate the angles. We first extend the inverted model in the reflection angle domain and derive a feasible pseudoextended Born modeling operator which can map the reflection angle-domain extended model to seismic data. The modeling operator, associated with an adjoint operator, are then used to build a pseudoextended linearized inversion framework for inverting the angle-dependent reflectivity. Taking advantage of the simplicity and coherency of the ADCIGs, we impose a series of low-rank constraints on the extended angle dimension and a sparse constraint on the whole dimension to ensure the production of high-quality ADCIGs. The proposed method is finally solved by a regularized conjugate gradient algorithm. We conduct several numerical examples on a flat layer model, the Marmousi model, and the Sigsbee2A salt model to test the validity and superiority of the proposed method. The results demonstrate that the proposed method could produce the ADCIGs and the stacked image with higher fidelity than RTM, which provides a reliable input for migration velocity analysis, anisotropic model building, and amplitude versus angle analysis.
Milk Yield and Composition of Lactating Cows Fed Steam-Flaked Sorghum and Graded Concentrations of Ruminally Degradable Protein (1998)

To determine the effect of various amounts of ruminally undegradable protein in the diets of lactating cows fed steam-flaked sorghum, 24 Holstein cows (90 +/- 50 d in milk) were assigned to three treatments: 0.8% urea, 6% soybean meal, or 5% fish meal. Respective percentages of ruminally undegradable protein in the diets (as a percentage of crude protein) were 30, 35, and 39%. All diets contained 37% alfalfa hay; 3 to 5% cottonseed hulls; 10 to 13% whole cottonseed; 39% steam-flaked sorghum (360 g/L); 5% of a molasses, mineral, and vitamin supplement; and the different protein supplements. Intake of dry matter was higher for cows fed urea than for cows fed soybean meal or fish meal diets. In cows that yielded more than 40 kg/d of milk (4 cows per treatment), the soybean meal and fish meal diets resulted in higher yields of milk and 3.5% fat-corrected milk and a greater efficiency of conversion of feed to milk than did the urea diet. Cows that yielded less than 40 kg/d of milk (4 cows per treatment) at the beginning of treatment tended to yield more milk when fed urea than when fed the protein supplements. Nutrient digestibilities were not greatly affected by source of N, suggesting a beneficial effect of urea supplementation on nutrient digestibilities because replacement of protein supplements with cottonseed products caused the neutral detergent fiber content of the urea diet to be about 7% higher than that of the other diets. These data show that response to ruminally undegradable protein in diets of lactating cows fed steam-flaked sorghum was related to milk yield.
Immunoprocedures for detecting human chorionic gonadotropin: clinical aspects and doping control (1997)

The pregnancy hormone human chorionic gonadotropin (hCG) is also present at low concentrations in plasma and urine of men and nonpregnant women. hCG immunoreactivity occurs in various molecular forms: Besides the intact hCG heterodimer, considerable amounts of proteolytically cleaved forms, free subunits, and fragments are found in plasma and urine. Especially in urine, proteolytic fragments constitute a major part of the hCG immunoreactivity. The different forms of hCG cross-react to various degrees in immunoassays and constitute a problem for standardization of specific hCG determinations. After injection of hCG (10,000 IU of Pregnyl; Organon), above-normal concentrations of hCG can be detected in serum and urine for 7-11 days. Most immunoassays for hCG also measure hCG beta. Quantitative hCG determinations are mainly performed on serum samples, and very few commercial hCG determinations have been validated for determination of urine samples. Considerable care must therefore be exercised when utilizing such assays to analyze urines for doping control.
Phase-Sensitive Sum-Frequency Spectroscopy (2012)

Phase-sensitive sum-frequency spectroscopy (SFS) allows the complete measurement of the complex spectra of surface nonlinear response coefficients. Similar to linear spectroscopy, the spectrum of the imaginary part of a surface response coefficient directly characterizes surface resonances without complication. This newly developed technique has greatly enhanced the capability of surface SFS and provides many new research opportunities for surface science. This article describes the experimental schemes and underlying theory for the technique and briefly reviews works that have clearly demonstrated its power.
Design-for-Testability for Synchronous Sequential Circuits that Maintains Functional Switching Activity (2008)

Design-for-testability (DFT) approaches that allow a synchronous sequential circuit to enter states that it cannot enter during functional operation improve the fault coverage achievable for the circuit. However, nonfunctional operation during test application may result in switching activity that is significantly higher than under functional operation. This may lead to unnecessary yield loss due to supply voltage droops that slow the circuit but will not occur during functional operation. To address this issue we describe a DFT approach and a test generation procedure that improve the fault coverage by slowing down the state transitions of certain state variables relative to others. Unlike approaches that are based on holding values of state variables stable for unlimited numbers of clock cycles, the proposed approach resumes functional operation every limited number of clock cycles. This is shown to result in maximum switching activity that is in most cases lower than that obtained under the application of a functional test sequence, and never needs to exceed it.
