Predicting Visible Image Differences Under Varying Display Brightness and Viewing Distance (2019)

Numerous applications require a robust metric that can predict whether image differences are visible or not. However, the accuracy of existing white-box visibility metrics, such as HDR-VDP, is often not good enough. CNN-based black-box visibility metrics have proven to be more accurate, but they cannot account for differences in viewing conditions, such as display brightness and viewing distance. In this paper, we propose a CNN-based visibility metric, which maintains the accuracy of deep network solutions and accounts for viewing conditions. To achieve this, we extend the existing dataset of locally visible differences (LocVis) with a new set of measurements, collected considering aforementioned viewing conditions. Then, we develop a hybrid model that combines white-box processing stages for modeling the effects of luminance masking and contrast sensitivity, with a black-box deep neural network. We demonstrate that the novel hybrid model can handle the change of viewing conditions correctly and outperforms state-of-the-art metrics.
Intensive recreational athletes in the prospective multinational ICD Sports Safety Registry: Results from the European cohort (2019)

Participants in recreational sports had less frequent appropriate and inappropriate shocks during physical activity than participants in competitive sports. Shocks did not cause death or injury. Recreational athletes with ICDs can engage in sports without severe adverse outcomes unless other reasons preclude continuation.
Tag-Aware Ordinal Sparse Factor Analysis for Learning and Content Analytics (2014)

Machine learning offers novel ways and means to design personalized learning systems wherein each student's educational experience is customized in real time depending on their background, learning goals, and performance to date. SPARse Factor Analysis (SPARFA) is a novel framework for machine learning-based learning analytics, which estimates a learner's knowledge of the concepts underlying a domain, and content analytics, which estimates the relationships among a collection of questions and those concepts. SPARFA jointly learns the associations among the questions and the concepts, learner concept knowledge profiles, and the underlying question difficulties, solely based on the correct/incorrect graded responses of a population of learners to a collection of questions. In this paper, we extend the SPARFA framework significantly to enable: (i) the analysis of graded responses on an ordinal scale (partial credit) rather than a binary scale (correct/incorrect); (ii) the exploitation of tags/labels for questions that partially describe the question{concept associations. The resulting Ordinal SPARFA-Tag framework greatly enhances the interpretability of the estimated concepts. We demonstrate using real educational data that Ordinal SPARFA-Tag outperforms both SPARFA and existing collaborative filtering techniques in predicting missing learner responses.
A Large Crow in the Doomed Saloon (2006)

My admiration for the vanishing profession of humans who check written copy before it reaches official print is, within certain limits, unbounded. They are being made extinct by such unpredictable inventions as spellcheck, but they have been invaluable though never infallible. Here are some musical memorabilia for their epitaphs.
Thermogalvanic Cells with Silver Iodide as a Solid Electrolyte (1964)

Experiments with the thermocells and are described and compared with theory. The combination of the solid electrolyte, , with iodine gas diffusion electrodes gives the iodine cell a figure of merit of and a theoretical efficiency of 5.1%. In operation of this cell, iodine gas is evolved at the cold electrode and consumed at the hot electrode. These electrode reactions are reversible. In the silver cell, complications are introduced by the formation of silver dendrites at the cathode.
Evolution of Non-Cryptographic Hash Function Pairs for FPGA-Based Network Applications (2015)

High-speed computer networks require rapid packet processing and flexibility which can be ensured by implementing network applications in field programmable gate arrays (FPGAs). Many network applications are based on fast lookup in hash tables. It is important to use such hash functions for these tables which utilize efficiently the limited memory resources of FPGAs. Cuckoo hashing improves this utilization by using more hash functions simultaneously. However, there is no known approach for selecting those functions which together produce the best results. Bio-inspired methods are used in this paper for evolving hash function pairs for FPGA-based network applications. The evolved hash functions are based on linear and non-linear feedback shift registers and can be efficiently implemented in FPGAs. The experiments were aimed at hashing of Internet Protocol addresses and it was shown that evolved solutions can achieve better table load factor in comparison with human-created solutions.
High-survivability network architecture for military communications (1987)

Photoluminescence study of carrier transfer among vertically aligned double-stacked InAs/GaAs quantum dot layers (2002)

Photoluminescence (PL) properties of self-organized quantum dots (QDs) in a vertically aligned double-layer InAs/GaAs QD structure are studied as a function of temperature from 10 to 290 K. The QDs in a sample with a 1.8 ML InAs seed layer and a second 2.4 ML InAs layer are found to self-organize in pairs of unequal sized QDs with clearly discernible ground-states transition energy. The unusual temperature behavior of the PL for such asymmetrical QD pairs provides clear evidence for carrier transfer from smaller to larger QDs by means of a nonresonant multiphonon-assisted tunneling process in the case of interlayer transfer and through carrier thermal emission and recapture within one layer.
Modeling of Wave Propagation in Inhomogeneous Media (2005)

We present a methodology providing a new perspective on modeling and inversion of wave propagation satisfying time-reversal invariance and reciprocity in generally inhomogeneous media. The approach relies on a representation theorem of the wave equation to express the Green function between points in the interior as an integral over the response in those points due to sources on a surface surrounding the medium. Following a predictable initial computational effort, Green's functions between arbitrary points in the medium can be computed as needed using a simple cross-correlation algorithm.
Real-Time Live-Cell Imaging Technology Enables High-Throughput Screening to Verify in Vitro Biocompatibility of 3D Printed Materials (2019)

With growing advances in three-dimensional (3D) printing technology, the availability and diversity of printing materials has rapidly increased over the last years. 3D printing has quickly become a useful tool for biomedical and various laboratory applications, offering a tremendous potential for efficiently fabricating complex devices in a short period of time. However, there still remains a lack of information regarding the impact of printing materials and post-processing techniques on cell behavior. This study introduces real-time live-cell imaging technology as a fast, user-friendly, and high-throughput screening strategy to verify the in vitro biocompatibility of 3D printed materials. Polyacrylate-based photopolymer material was printed using high-resolution 3D printing techniques, post-processed using three different procedures, and then analyzed with respect to its effects on cell viability, apoptosis, and necrosis of adipogenic mesenchymal stem cells (MSCs). When using ethanol for the post-processing procedure and disinfection, no significant effects on MSCs could be detected. For the analyses a novel image-based live-cell analysis system was compared against a biochemical-based standard plate reader assay and traditional flow cytometry. This comparison illustrates the superiority of using image-based detection of in vitro biocompatibility with respect to analysis time, usability, and scientific outcome.

Radioactivity Analysis of DUPIC Fuel Fabrication Process According to Burn-Up and Cooling Time (2005)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Unusual regulation of expression of the herpes simplex virus DNA polymerase gene (1993)

During herpes simplex virus infection, expression of the viral DNA polymerase (pol) gene is regulated temporally as an early (beta) gene and is additionally down-regulated at late times at the level of translation (D. R. Yager, A. I. Marcy, and D. M. Coen, J. Virol. 64:2217-2225, 1990). To examine the role of viral DNA synthesis in pol regulation, we studied pol expression during infections in which viral DNA synthesis was blocked, either by using drugs that inhibit Pol or ribonucleotide reductase or by using viral mutants with lesions in either the pol or a primase-helicase subunit gene. Under any of these conditions, the level of cytoplasmic pol mRNA was reduced. This reduction was first seen at approximately the time DNA synthesis begins and, when normalized to levels of other early mRNAs, became as great as 20-fold late in infection. The reduction was also observed in the absence of the adjacent origin of replication, oriL. Thus, although pol mRNA accumulated as expected for an early gene in terms of temporal regulation, it behaved more like that of a late (gamma) gene in its response to DNA synthesis inhibition. Surprisingly, despite the marked decrease in pol mRNA in the absence of DNA synthesis, the accumulation of Pol polypeptide was unaffected. This was accompanied by loss of the normal down-regulation of translation of pol mRNA at late times. We suggest a model to explain these findings.
Accurate FEA-Based Modeling of IPMSMs Operating Under High Magnetic Utilization (2022)

In this work, an automotive interior permanent-magnet synchronous machine (IPMSM) with double V-shape rotor magnets under high magnetic utilization is investigated. Most IPMSM models nowadays use finite element analyses (FEAs) to build look-up-tables in order to account for the dependency of the direct and quadrature inductances (L <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</inf> and L <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</inf> ) on the values of the direct and quadrature currents (i <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">d</inf> and i <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">q</inf> ). However, these models make assumptions that lead to inaccuracy of the machine’s parameters. First, that the difference between the differential inductances and the absolute inductances of the machine is neglected; second, that there is no cross-coupling between the inductances (L <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">dq</inf> and L <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">qd</inf> ); and third, that all the magnet flux linkage is oriented along the d-axis, while ignoring the q-axis magnet flux linkage. The effects of these three assumptions can be considerable according to the results of this study. In this paper, an analysis of the saturation effects of the material with a focus on the often-neglected quantities is performed. The parameters of the extended model of the IPMSM, derived from finite element analyses, are contrasted with those derived for the simplified model of the machine.
Framework for rapid prototyping of distributed IoT applications powered by WebRTC (2016)

We argue that the future of Internet of Things (IoT) systems, especially when it comes to privacy and security, lies in distributed IoT applications. Distributed IoT applications implement a model we call "computation follows data". In this model, application modules are deployed directly on IoT devices that produce sensitive data. Developing such applications is, however, not easy. Based on our own experience, we identify the lack of a rapid prototyping and development environment as the biggest challenge in the development process. In this paper, we describe a framework that aims to help simplify the process. The framework provides a web-based user interface with interactive virtual IO ports and a runtime environment for IoT device emulation. We also describe a network architecture with support for WebRTC-based direct device-to-device connections. The network architecture allows experimentation with an entire network of IoT devices, both emulated and physical.
Hypergraph partitioning with fixed vertices [VLSI CAD] (2000)

We empirically assess the implications of fixed terminals for hypergraph partitioning heuristics. Our experimental testbed incorporates a leading-edge multilevel hypergraph partitioner and IBM-internal circuits that have recently been released as part of the ISPD-98 Benchmark Suite. We find that the presence of fixed terminals can make a partitioning instance considerably easier (possibly to the point of being "trivial"); much less effort is needed to stably reach solution qualities that are near best-achievable. Toward development of partitioning heuristics specific to the fixed-terminals regime, we study the pass statistics of flat FM-based partitioning heuristics. Our data suggest that more fixed terminals implies that the improvements within a pass will more likely occur near the beginning of the pass. Restricting the length of passes-which degrades solution quality in the classic (free-hypergraph) context-is relatively safe for the fixed-terminals regime and considerably reduces the run times of our FM-based heuristic implementations. The distinct nature of partitioning in the fixed-terminals regime has deep implications: (1) for the design and use of partitioners in top-down placement; (2) for the context in which VLSI hypergraph partitioning research is pursued; and (3) for the development of new benchmark instances for the research community.
Bioprinted 3D Outer Retina Barrier Uncovers RPE-dependent Choroidal Phenotype in Advanced Macular Degeneration (2021)

Abstract Age-related macular degeneration (AMD), a leading cause of blindness, initiates in the outer-blood-retina-barrier (oBRB) formed by Retinal pigment epithelium (RPE), Bruch’s membrane, and choriocapillaris. The mechanism of AMD initiation and progression remain poorly understood due to the lack of physiologically relevant oBRB models. We engineered a native-like 3D-oBRB tissue by bioprinting endothelial cells, pericytes, and fibroblasts on the basal side of a biodegradable scaffold and establishing an RPE monolayer on top. In this 3D-oBRB, a fully-polarized RPE monolayer with apical processes and basal infoldings provides barrier resistance, induces fenestration and choroid-specific gene expression in the choriocapillaris, and supports the formation of a Bruch’s-like membrane that allows tissue integration in rat eyes. Complement activation in the 3D-oBRB triggers dry-AMD phenotypes (including subRPE drusen and choriocapillaris degeneration), and hypoxia activated HIF-α induces wet-AMD phenotypes (choriocapillaris neovascularization). Anti-VEGF drug treatment suppresses neovascularization - validating this model for clinical translation and drug discovery.
Research on the FP Growth Algorithm about Association Rule Mining (2008)

For large databases, the research on improving the mining performance and precision is necessary, so many focuses of today on association rule mining are about new mining theories, algorithms and improvement to old methods. Association rules mining is a function of data mining research domain and arise many researchers interest to design a high efficient algorithm to mine association rules from transaction database. Generally all the frequent item sets discovery from the database in the process of association rule mining shares of larger, the price is also spending more. This paper introduces an improved aprior algorithm so called FP-growth algorithm that will help resolve two neck-bottle problems of traditional apriori algorithm and has more efficiency than original one. In theoretic research, An anatomy of two representative arithmetics of the Apriori and the FP Growth explains the mining process of frequent patterns item set. The constructing method of FP tree structure is provided and how it affects association rule mining is discussed. Experimental results show that the algorithm has higher mining efficiency in execution time, memory usage and CPU utilization than most current ones like Apriori.

Exact Covers via Determinants (2009)

Given a k-uniform hypergraph on n vertices, partitioned in k equal parts such that every hyperedge includes one vertex from each part, the k-dimensional matching problem asks whether there is a disjoint collection of the hyperedges which covers all vertices. We show it can be solved by a randomized polynomial space algorithm in time O*(2^(n(k-2)/k)). The O*() notation hides factors polynomial in n and k. When we drop the partition constraint and permit arbitrary hyperedges of cardinality k, we obtain the exact cover by k-sets problem. We show it can be solved by a randomized polynomial space algorithm in time O*(c_k^n), where c_3=1.496, c_4=1.642, c_5=1.721, and provide a general bound for larger k. Both results substantially improve on the previous best algorithms for these problems, especially for small k, and follow from the new observation that Lovasz' perfect matching detection via determinants (1979) admits an embedding in the recently proposed inclusion-exclusion counting scheme for set covers, despite its inability to count the perfect matchings.
A Novel Hybrid Five-Level Voltage-Source Converter Based on T-Type Topology for High-Efficiency Applications (2017)

A novel hybrid five-level voltage-source converter for high-efficiency applications is investigated in this paper. Compared with traditional multilevel converters, this hybrid multilevel converter generates desired staircase voltage levels with a reduced number of power devices and isolated drivers at higher voltage levels. It has redundant switching state combinations in hybrid multilevel converter, which makes it easy to balance flying capacitor voltages and realize fault-tolerant operation. A voltage-balancing control strategy based on switching state redundancies is presented for the hybrid multilevel converter to generate desired levels and also keep voltage balance of flying capacitors at the same time. The performance of the hybrid multilevel converter under various operating conditions is investigated in MATLAB/Simulink. The effectiveness of the proposed hybrid multilevel converter is validated by experiment results.

Identification of a Novel Metallo-^|^beta;-Lactamase VIM-28 Located within Unusual Arrangement of Class 1 Integron Structure in Pseudomonas aeruginosa Isolates from Egypt (2014)

Two multidrug-resistant Pseudomonas aeruginosa strains harboring blaVIM were isolated from a hospital in Egypt and were indistinguishable by pulsed-field gel electrophoresis. Sequence analysis revealed a novel VIM β-lactamase, VIM-28. Additional sequencing of integron revealed that the blaVIM-28 gene cassette had an unusual arrangement of class 1 integron structure, located directly downstream of the integrase gene "intI1" and oriented divergently from it. The new organization of integron also comprised the aacA7 and smr-2 gene cassettes in that order. A complete ISPa21 containing a tnpA gene flanked by two 13-bp inverted repeats was located directly upstream of the 3'-CS conserved region of the integron containing qacEΔ1/sul1 genes. The blaVIM-28-containing class 1 integron was found to have a chromosomal origin in both strains. In conclusion, the presence of a new variant of blaVIM, blaVIM-28, on a new organization of class 1 integron having ISPa21 increases the possibility of dissemination of resistance genes within the integron in P. aeruginosa among hospitalized patients in Egypt.
The expression and modulation of human myeloid-specific antigens during differentiation of the HL-60 cell line (1983)

Antigenic changes detected by myeloid-specific monoclonal antibodies on HL-60 cells induced to differentiate by various chemical mediators were investigated using flow cytometry. Antigen levels detected by monocyte- granulocyte-specific monoclonal antibodies AML-2–23, 61D3, and 63D3 increased dramatically after differentiation of HL-60 cells along the granulocytic pathway by the addition of dimethyl formamide (DMF), dimethylsulfoxide (DMSO), or cis-retinoic acid. The expression of these same antigens also increased in conjunction with monocytoid differentiation when HL-60 cells were treated with supernatants from leukocytes stimulated with phytohemagglutinin (PHA-LCM) or with mixed lymphocyte conditioned medium (MLC). In contrast, treatment of HL-60 cells with phorbol 12-myristate 13-acetate (PMA), which also induced differentiation along the monocyte pathway, had no effect on the expression of these monocyte-associated antigens. The expression of antigens on HL-60 cells recognized by the granulocyte-specified monoclonal antibodies PMN 6 and PMN 29 decreased after treatment of HL- 60 cells with PMA, but remained constant after treatment with DMF, DMSO, cis-retinoic acid, PHA-LCM, or MLC. These results suggest that normal myeloid differentiation may be dependent on various signals and that morphological and cell surface marker maturity may, under some conditions, be separable. The utility of the HL-60 cell line as a model of myeloid differentiation and for evaluation of inductive signals is discussed.
