Event-based multimedia chronicling systems (2005)

This paper presents a new framework for multimedia electronic chronicling systems.Its approach uses events as its driving force for heterogeneous information processing. Specifically,this new approach .rst separates symbols and data, then puts events between them to make a distinct connection.In addition,this approach provides spatio-temporal- semantic relations networks to map high-level semantic user queries into low-level queries that a machine can compute. The innovative user interfaces are designed for ease of use and are interactive to allow organization of information and a search capability for information retrieval. The results reported as a part of this paper show that we can achieve effective chronicling and high-quality user experiences by coupling together multimedia analysis,tagging and querying. We believe that our system can serve as a semantically accessible annotated multimedia log.The approach taken here may provide a foundation to provide further summaries of important events or access to events at the required level of granularity.

The Coiled-Coil Domain of the Adenovirus Type 5 Protein IX Is Dispensable for Capsid Incorporation and Thermostability (2005)

The 14.4-kDa hexon-associated protein IX (pIX) acts as a cement in the capsids of primate adenoviruses and confers a thermostable phenotype. Here we show that deletion of amino acids 100 to 114 of adenovirus type 5 pIX, which eliminates the conserved coiled-coil domain, impairs its capacity to self-associate. However, pIXDelta100-114 is efficiently incorporated into the viral capsid, and the resulting virions are thermostable. Deletion of the central alanine-rich domain, as in pIXDelta60-72, does not impair self-association, incorporation into the capsid, or the thermostable phenotype. These data demonstrate, first, that the self-association of pIX is dispensable for its incorporation into the capsid and generation of the thermostability phenotype and, second, that the increased thermostability results from pIX monomers binding to different hexon capsomers rather than capsid stabilization by pIX multimers.
Resisting Multiple Advanced Persistent Threats via Hypergame-Theoretic Defensive Deception (2023)

Existing defensive deception (DD) approaches apply game theory, assuming that an attacker and defender play the same, full game with all possible strategies. However, in deceptive settings, players may have different beliefs about the game itself. Such structural uncertainty is not naturally handled in traditional game theory. In this work, we formulate an attackdefense hypergame where multiple advanced persistent threat (APT) attackers and a single defender play a repeated game with different perceptions. The hypergame model systematically evaluates how various DD strategies can defend proactively against APT attacks. We present an adaptive method to select an optimal defense strategy using hypergame theory for strategic defense as well as machine learning for adaptive defense. We conducted in-depth experiments to analyze the performance of the eight schemes including ours, baselines, and existing counterparts. We found the DD strategies showed their highest advantages when the hypergame and machine learning are considered in terms of reduced false positives and negatives of the NIDS, system lifetime, and players’ perceived uncertainties and utilities. We also analyze the Hyper Nash Equilibrium of given hypergames and discuss the key findings and insights behind them.
An experimental adaptive nulling receiver utilizing the sample matrix inversion algorithm with channel equalization (1991)

The authors explore two ideas for effectively achieving channel equalization within the framework of a narrowband sidelobe canceler. The first approach relies primarily on digital equalization to enhance conventional sample matrix inversion (SMI) performance, whereas the second utilizes feedback to extend the SMI method into the realm of analog adaptive cancellation. An experimental four-channel receiver that supports open-loop and closed-loop operation is described. As implemented, three different canceler modes are possible: feedforward, feedback, and a tandem feedback/feedforward combination. All three modes have been successfully demonstrated in bench experiments with a broadband noise source using the SMI algorithm. Cancellation ratios in excess of 50 dB have been achieved in a four-channel testbed system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
FOLKSOMAPS - towards community driven intelligent maps for developing regions (2009)

Many services taken for granted in the developed world are often missing from the developing countries. One typical example is that of map systems that form the basis of several location driven services. Its heavy reliance on content, provides a huge barrier towards building such systems. Further, in developing countries like India, the infrastructure typically has a history of unplanned development, leading to unorganized addresses and absence of standard naming conventions for roads. Detailed map systems such as online maps have only recently started becoming available but for major cities. Remote towns and villages remain out of reach till date. In this paper, we investigate a community-driven approach for creating maps in developing regions - following Web 2.0 principles, but not entirely relying on the existing Web. Our system, dubbed FOLKSOMAPS is an intelligent, community constructed map system, particularly architected with developing regions in mind. We present the design of FOLKSOMAPS, followed by an implementation of our proof-of-concept system. We present user studies aimed at understanding the uptake, usability and utility of FOLKSOMAPS. The results indicate a strong need for such a community-generated mapping ecosystem.

African American Race is Not Associated with Risk of Reclassification during Active Surveillance: Results from the Canary Prostate Cancer Active Surveillance Study (2019)

Of men on active surveillance who followed a standardized protocol of regular prostate specific antigen testing and biopsy those who were African American were not at increased risk for pathological reclassification while on active surveillance, or for adverse pathology findings at prostatectomy. Active surveillance appears to be an appropriate management strategy for African American men with favorable risk prostate cancer.
Circannual Changes in Serum Testosterone Concentrations of Adult and Yearling Woodchucks (Marmota Monax)1 (1985)

Testicular volumes and serum testosterone concentrations were determined biweekly in 5 adult and 4 yearling woodchucks maintained indoors from December through August. Food and water were provided ad libitum except for 2 mo beginning at the winter solstice when feeding and lighting (12L:12D) supplemental to available natural light were discontinued. Temperatures fluctuated with outdoor temperatures greater than 4 degrees C. No significant hibernation occurred. Testes in adults were small in December (0.3-1.8 cm3), largest in February and March (3.5-5.6 cm3), and smallest in late June (0.1-0.5 cm3). Testosterone was basal in December (less than 0.6 ng/ml), maximal (3.4-6.6 ng/ml) between early January and late March, and minimal from April through August (less than 0.8 ng/ml). In yearlings, maximum testes volumes (1.6 cm3) and serum testosterone (0.9 +/- 0.2 ng/ml) were less, and occurred later, than in adults. Testosterone levels and testis volumes measured in newly captured woodchucks in March and April and again 2-3 mo later were generally similar to those of their laboratory counterparts. Thus, in woodchucks: annual cycles of testosterone production and of testes recrudescence and regression parallel each other with maxima during the short, late-winter breeding season; those cycles are not altered significantly by the absence of hibernation or the present conditions of captivity; and yearling males apparently are not an important part of the breeding population.
Elucidation of the Scale Prevention Effect by Alternating Magnetic Treatment (2007)

Process industry remains skeptical of the effect of scale prevention in a water pipe by magnetic treatment despite its long history. In this study, mechanism of scale prevention by “alternating” magnetic treatment was investigated. Using suspensions of non‐magnetic colloid particles (TiO2 or CaCO3) dispersed in an electrolytic solution, we investigated zeta potential changes of the particles by imposition of alternating magnetic field with a specific frequency. Consequently, we found that the specific frequency treatment (several kHz) changes the zeta potential of particles drastically with an inversion of sign. This phenomenon obviously depends on the frequency. It is considered to be due to the specific adsorption of anions, that were easily adsorbed, in the solution onto the particles interface. From the experimental results, we concluded the mechanism of scale prevention by the treatment as follows: Normally, a surface of inner wall of a water pipe has negative charge and surface of scale particles in water has positive charge. So the particles are attracted by the water pipe and are attached to it. After the treatment, surface potential of the particles shifts to negative side, then repulsive force is formed between the particles and the wall.
186 A Multi-Center, Randomized, Placebo-Controlled, Double-Blinded Trial of Efficacy and Safety of Riluzole in Acute Spinal Cord Injury Study (RISCIS) (2023)

INTRODUCTION: Riluzole, a sodium-glutamate antagonist which is FDA approved for ALS has shown promising pre-clinical results and is clinically safe in SCI patients. METHODS: The RISCIS trial is an international, multi-center, prospective, double-blinded, randomized, placebo-controlled Phase II/III trial. Patients with ASIA A-C, C4-C8 SCI and &lt;12 hours from injury were randomized between Riluzole, at an oral dose of 100mg BID for the first 24 hours followed by 50mg BID for the following 13 days, and placebo control. RESULTS: Due to the impact of the global COVID-19 pandemic this trial was terminated prior to completion. 193 patients were randomized with a follow-up rate of 82.7% at 180-days. No statistical difference was noted in the demographics and baseline injury characteristics between the two groups. At 6 months there was a median gain in total motor scores (TOTM) of 30.0 in the Riluzole group compared to 20.0 for the Placebo group. The improved motor outcomes did not reach statistical significance. Given the decreased sample size, additional sensitivity analyses were conducted. In the ASIA-C population, Riluzole was a significant improver of total motor scores (coefficient estimate: 14.10, p = 0.020) and upper motor scores (CE: 7.68, p = 0.040) at 6 months. ASIA B patients had higher reported independence, as measured by the SCIM score (45.3 vs. 27.3; p = 0.071) and change in mental health scores as measured by the SF-36 mental health domain (2.01 vs. -11.58; p: 0.0205) at 180 days. CONCLUSIONS: Despite the premature termination of the RISCIS trial due to the COVID-19 pandemic, 193 subjects were recruited into this trial. Primary analysis showed a 10-motor point gain in riluzole-treated subjects which did not reach significance. However, on secondary analysis, incomplete cervical SCI subjects (AIS B and C) showed significant gains in functional recovery.

Attenuation of Lipopolysaccharide-Induced Inflammatory Responses through Inhibition of the NF-κB Pathway and the Increased NRF2 Level by a Flavonol-Enriched n-Butanol Fraction from Uvaria alba (2023)

Pathologic hyperreactive inflammatory responses occur when there is excessive activation of a proinflammatory NF-κB pathway and a reduced cytoprotective NRF2 cascade. The noncytotoxic, highly selective COX-2 inhibitory flavonol-enriched butanol fraction (UaB) from <i>Uvaria alba</i> (<i>U. alba</i>) was investigated for its inflammatory modulating potential by targeting NF-κB activation and NRF2 activity. Enzyme-linked immunosorbent assay was initially performed to measure levels of proinflammatory mediators [nitric oxide (NO), prostaglandin E<sub>2</sub>, and reactive oxygen species (ROS)] and cytokines [tumor necrosis factor-alpha (TNF-α), IL-1β, and IL-6], followed by reverse transcription-polymerase chain reaction and western blotting to determine mRNA and protein expression, respectively. Using immunofluorescence staining combined with western blot analysis, the activation of NF-κB was further investigated. NRF2 activity was also measured using a luciferase reporter assay. UaB abrogated protein and mRNA expressions of inducible nitric oxide synthase (iNOS), COX-2, TNF-α, IL-1β, and IL-6 in RAW 264.7 macrophages, thereby suppressing the production of proinflammatory mediators and cytokines. This was further validated when a concentration-dependent decrease in NO and ROS production was observed in zebrafish (<i>Danio rerio</i>) larvae. UaB also increased NRF2 activity in HaCaT/ARE cell line and attenuated NF-κB activation by inhibiting the nuclear translocation of transcription factor p65 in RAW 264.7 macrophages. Nontargeted LC-MS analysis of UaB revealed the presence of the flavonols quercitrin (<b>1</b>), quercetin (<b>2</b>), rutin (<b>3</b>), kaempferol (<b>4</b>), and kaempferol 3-<i>O</i>-rutinoside (<b>5</b>). Molecular docking indicates that major flavonol aglycones have high affinity toward COX-2 NSAID-binding sites, TNF-α, and TNF-α converting enzyme, while the glycosylated flavonoids showed strong binding toward iNOS and IKK-all possessing dynamic stability when performing molecular dynamics simulations at 140 ns. This is the first report to have elucidated the mechanistic anti-inflammatory potential of the Philippine endemic plant <i>U. alba</i>.

Mathematical Proof Between Generations (2022)

A proof is one of the most important concepts of mathematics. However, there is a striking difference between how a proof is defined in theory and how it is used in practice. This puts the unique status of mathematics as exact science into peril. Now may be the time to reconcile theory and practice, i.e. precision and intuition, through the advent of computer proof assistants. For the most time this has been a topic for experts in specialized communities. However, mathematical proofs have become increasingly sophisticated, stretching the boundaries of what is humanly comprehensible, so that leading mathematicians have asked for formal verification of their proofs. At the same time, major theorems in mathematics have recently been computer-verified by people from outside of these communities, even by beginning students. This article investigates the gap between the different definitions of a proof and possibilities to build bridges. It is written as a polemic or a collage by different members of the communities in mathematics and computer science at different stages of their careers, challenging well-known preconceptions and exploring new perspectives.

Application of Adaptive Control to a Nuclear Power Plant (1986)

Possible applications of an adaptive control method to a pressurized water reactor nuclear power plant are investigated. A self-tuning control algorithm with the generalized minimum variance strategy is employed. The control system design is based on a second-order linear model with unknown, time-varying parameters. To ensure that this low-order model describes the complex “real” dynamics well enough for control purposes, control parameters are updated on line with a recursive estimation sequence based on an extended least-squares method. The average coolant temperature is held as close as possible to a desired (but changing) reference value in the load-following mode of operation. The control rod position is selected as the control variable. Simulation results for such a system are encouraging and demonstrate the possibility of using this adaptive control method in an actual plant.
The Mammalian Homolog of the Frog Type II Selenodeiodinase Does Not Encode a Functional Enzyme in the Rat* (1999)

Type II iodothyronine deiodinase is a short-lived, membrane-bound enzyme found in rat brain, brown adipose tissue, and cAMP-stimulated astrocytes. Recently, a full-length complementary DNA (cDNA) encoding a 30-kDa, type II-like selenodeiodinase was cloned from frog, and a homologous partial cDNA (rBAT 1.1), containing two in-frame selenocysteine codons (UGA), was isolated from rat brown adipose tissue. Importantly, the rBAT 1.1 cDNA was derived from a 7.5-kb messenger RNA (mRNA) and did not encode a functional selenoenzyne unless an enabling selenocysteine insertion sequence was appended to the presumed coding region and this cDNA. In this study we determined whether the native 7.5-kb SeD2 mRNA in rat tissues programmed the synthesis of the native type II deiodinase using specific antibodies that were raised against the C-terminus of full-length, 30-kDa SeD2 protein and against the catalytic core of SeD2. Direct analysis of the translation products programmed by the native SeD2 mRNA in cAMP-stimulated astrocytes was performed using antisense deoxynucleotides and hybrid selection strategies. (Bu)2cAMP-stimulated rat astrocytes expressed both type II deiodinase activity (approximately 2500 U/mg protein) and contained abundant levels of the 7.5-kb SeD2 mRNA. However, no immunoreactive 30-kDa SeD2 protein was identified by Western analysis, immunoprecipitation, or immunocytochemistry, and the specific C-terminus antiserum failed to immunoprecipitate deiodinase activity from (Bu)2cAMP-stimulated astrocytes, brown adipose tissue or brain. Instead, the native 7.5-kb SeD2 mRNA encoded a 15-kDa protein that terminated at the first UGA codon and contained the catalytically inactive, N-terminal 129 amino acids of SeD2. These data show that the native 7.5-kb SeD2 mRNA in stimulated astrocytes does not encode D2.
Studies of the resonance structure in $$D^{0} \rightarrow K^\mp \pi ^\pm \pi ^\pm \pi ^\mp $$ D 0 → K ∓ π ± π ± π ∓ decays (2018)

A Novel, High Range-to-Resolution Ratio, Optical Sensing Technique for High Speed Surface Geometry Measurements (1987)

A novel combination of image formation theory, along with optimal digital estimation theory was employed in development of a new optical probe suitable for a variety of high speed sensing applications, such as in-process manufactured part inspection. Experimental results demonstrate a robust, 40,000:1 range-to-resolution ratio. The sensing strategy also utilizes multiple, simultaneous illumination beams such that it is possible to accurately estimate surface orientation for robotic guidance applications. A significant element in this research was the development of a technique which is least influenced by surface finish roughness as commonly found on manufactured surfaces. Experimental results are provided to demonstrate the validity of the theoretical models.
Learning Rich Features for Image Manipulation Detection (2018)

Image manipulation detection is different from traditional semantic object detection because it pays more attention to tampering artifacts than to image content, which suggests that richer features need to be learned. We propose a two-stream Faster R-CNN network and train it end-to-end to detect the tampered regions given a manipulated image. One of the two streams is an RGB stream whose purpose is to extract features from the RGB image input to find tampering artifacts like strong contrast difference, unnatural tampered boundaries, and so on. The other is a noise stream that leverages the noise features extracted from a steganalysis rich model filter layer to discover the noise inconsistency between authentic and tampered regions. We then fuse features from the two streams through a bilinear pooling layer to further incorporate spatial co-occurrence of these two modalities. Experiments on four standard image manipulation datasets demonstrate that our two-stream framework outperforms each individual stream, and also achieves state-of-the-art performance compared to alternative methods with robustness to resizing and compression.
