Society Of Photo-Optical Instrumentation Engineers 1987 Technical Symposium Southeast Optics, Electro-Optics, And Sensors (1987)

Traditional training methods usually provide for alternating free practice trials with demonstrations of ideal or desired performance. Current work at the University of Central Florida's Human Factors Laboratory has tested the feasibility of simultaneously coupling direct practice with exposure to a proficient model's behavior. By optically superimposing a videotape of a model's execution of the task on the student's video terminal during training, subjects can practice complex skills such as an aircraft carrier launch and approach to landing by mimicking the altitude, pitch and roll demonstrated by the model. Results suggest that coupling direct practice with simultaneous exposure to the modeled demonstrations yields the same level of proficiency with a 33% savings in training time.

Imagerie des cancers en tomographie par émission de positons. (1999)

Positron emission tomography (PET) is a method making use of short half-life radioactive compounds which allow imaging and quantification of functional and metabolic data at the level of multiple organs. This method has been initially oriented towards neurological and cardiological applications but gets now a more widespread use in oncology. This recent development has been made possible thanks to methodological progresses allowing "whole body" imaging and thanks to the use of a practical tracer, the 2-[18 F]fluoro-2-deoxy-D-glucose (FDG). The uptake of this tracer is enhanced in diverse cancer tissues. Recent studies has clarified the biological processes which lead to this enhanced uptake of FDG in cancers. This new insight allows a rational and helpful usage of PET in diverse aspects of clinical oncology: diagnosis of lesion, staging, follow-up of patients and treatment evaluation.
Male Pseudohermaphroditism due to 17,20-Desmolase Deficiency (1983)

In a 5-yr-old 46,XY male pseudohermaphrodite with microphallus, perineal hypospadias, chordee and cryptorchidism, serum C19 steroid levels were abnormally low in the basal state and after adrenal and testicular stimulation. Serum C21 steroid levels were elevated in the basal state and increased further after adrenal, but not after gonadal, stimulation. Urinary excretion of pregnanetriolone, a metabolite of 17-hydroxypregnenolone and 17-hydroxyprogesterone not normally present in the urine, was increased in the basal and stimulated states. Cortisol production was normal, and all steroid hormone levels were suppressed by dexamethasone. Testicular biopsy was consistent with prepubertal cryptorchid testes. Incubation of testicular tissue with labeled 17-hydroxyprogesterone revealed failure of conversion of precursor to androstenedione and testosterone. A significant increase in phallic length occurred after treatment with exogenous androgen. These findings are consistent with 17,20-desmolase deficiency in both gonads and adrenal glands.
Calculation of the Performance of Communication Systems From Measured Oscillator Phase Noise (2014)

Oscillator phase noise (PN) is one of the major problems that affect the performance of communication systems. In this paper, a direct connection between oscillator measurements, in terms of measured single-side band PN spectrum, and the optimal communication system performance, in terms of the resulting error vector magnitude (EVM) due to PN, is mathematically derived and analyzed. First, a statistical model of the PN, considering the effect of white and colored noise sources, is derived. Then, we utilize this model to derive the modified Bayesian Cramér-Rao bound on PN estimation, and use it to find an EVM bound for the system performance. Based on our analysis, it is found that the influence from different noise regions strongly depends on the communication bandwidth, i.e., the symbol rate. For high symbol rate communication systems, cumulative PN that appears near carrier is of relatively low importance compared to the white PN far from carrier. Our results also show that 1/f <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> noise is more predictable compared to 1/f <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> noise and in a fair comparison it affects the performance less.
THE PERFORMANCE-BASED INTERLINKED MODEL (PBIM) IN ARCHITECTURAL DESIGN: EXCHANGING ENVIRONMENTAL, STRUCTURAL AND SPATIAL PARAMETERS IN THE EARLY DESIGN STAGE (2021)

The paper aims to present a model that generates a framework for incorporating different types of performance issues into the conceptual design to improve the decision-making process of students by extracting only the critical parameters and demonstrate its applicability in the context of architectural education. The proposed Performance-based Interlinked Model (PBIM) seeks to address the question of whether design and performance parameters can be evaluated together in the early design stage, where conceptual ideas are explored, by integrating knowledge taught in different types of courses in architectural education, including design, building science and technology. The salient pedagogical approach consists in three stages—namely, generating the design model, applying the selected method for performance computation—including solar radiation, daylight, structural, wind flow and spatial analyses— and regenerating the design model by extracting critical performanceparameters. Data is collected via a process-analysis method driven by case studies, and a network graph is generated that visualizes the data. The degree and centrality values of the graph are then extracted to assess the individual contribution of the parameters in the architectural design process. The PBIM is validated by calculating the Sensitivity Rate (SR) for each study. The proposed model enables the integrated evaluation of design and performance parameters and the enhancement of students’ decision-making process concerning performance analysis.
Doppler myocardial imaging in adult male rats: Reference values and reproducibility of velocity and deformation parameters (2006)

DMI is feasible and reproducible in healthy rats. Establishing reference values opens new perspectives towards the use of strain and strain rate imaging in small rodents in the assessment of myocardial diseases.
A blue-green alga from Okinawa contains aplysiatoxins, the third class of tumor promoters. (1985)

The causative agents of swimmer's itch were isolated from the marine blue-green alga, Lyngbya majuscula, which grows off the coast of the Okinawa islands, Japan. Nuclear magnetic resonance and mass spectral studies revealed that these agents were identical with aplysiatoxin and debromoaplysiatoxin, which were previously shown to be the causative agents of swimmer's itch in Hawaii. Aplysiatoxin and debromoaplysiatoxin were recently found to be potent tumor promoters in two-stage carcinogenesis in mouse skin. This is the first report that humans are directly affected by these potent environmental tumor promoters in Japan.
Leptomycin B induces apoptosis in cells containing the whole HPV 16 genome (2009)

Cervical cancer is a major cause of death in women worldwide and is strongly associated with human papillomavirus (HPV) infection. Integration of HPV is thought to be a key step in malignant progression, and is associated with loss of regulation of the viral E6 and E7 oncogenes. Leptomycin B (LMB), a nuclear export inhibitor, has previously been shown to induce apoptosis in primary keratinocytes transduced with the HPV 16 E7 or E6/E7 genes, but not in normal cells. We show here that LMB can also induce apoptosis in derivatives of the W12 cell line that contain either episomal or integrated HPV 16. Cells transduced with HPV 16 E7 or E6/E7, and the episomal and integrated W12 derivatives showed distinct temporal expression patterns of the apoptotic markers activated caspase-3 and M30. The expression of both markers occurred later in the episomal derivatives than in either transduced cells or W12 derivatives containing integrated HPV. These findings suggest that, although LMB can induce apoptosis in keratinocytes containing episomal or integrated HPV 16, genome status is likely to influence the response of HPV-associated anogenital lesions to LMB treatment.

Understanding the Influence of SO2 and O2 on the Corrosion of Carbon Steel in Water-Saturated Supercritical CO2 (2014)

In this work, the general and localized corrosion behavior of X65 carbon steel in water-saturated supercritical CO2 conditions containing O2 and SO2 at 35°C and 80 bar is evaluated. The results indicate that crystalline FeCO3 formed in the presence of water and CO2; however, the combined introduction of small concentrations of O2 and SO2 (as low as 20 ppm and 2 ppm, respectively) changed its crystal morphology. Increasing the concentration of SO2 to 50 ppm and 100 ppm, while maintaining O2 content at 20 ppm, results in the formation of FeSO3 · 3 H2O. General corrosion rates increased significantly from 0.1 mm/y to 0.7 mm/y as a result of the increase in SO2 content from 0 ppm to 100 ppm based on 48 h experiments, while localized corrosion rates rose from 0.9 mm/y to 1.7 mm/y. Additional tests involving solution replenishment over 48 h indicated that the higher corrosion rates observed in the presence of SO2 did not present the worst case scenario corrosion rates and highlight the importance of having a system where the process fluid is continuously replenished. The corrosion product morphology and chemistry were identified through a combination of scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDX), x-ray diffraction (XRD), and surface profilometry measurements.
Methods for estimating the autocorrelation function of complex Gaussian stationary processes (1987)

New methods for estimating the autocorrelation function (acf) of a complex Gaussian stationary process are presented. These methods are based on a general invariance property for the autocorrelation of a common class of the above processes. This property suggests estimation procedures based on magnitude hard limiting and phase quantization. The procedures are an extension of the relay estimator, currently employed for real processes. The computational cost and the general properties of the methods are discussed. In particular, some estimators especially suited for very simple implementations are considered. The performance of the complex hybrid sign estimator is evaluated and compared to that of the classical Direct estimator. The proposed methods are attractive for many applications in the field of digital signal processing.
Time-Dependent Phenomena in Neutron Slowing Down Theory (1972)

The analysis of the slowing down of a neutron pulse leads to a detailed analogy between the decay of a pulse in the fast regime versus the decay in the thermal energy region. It is found that the slope, α, of log N(t) versus log(t) depends on the system buckling, B2. An “α versus B2” curve exists that is analogous to the “λ versus B2” curve for thermal systems. Other analogies between fast and thermal time decay are discussed. These analogies exist despite the fact that no time eigenvalue exists for this slowing down problem.
Regulation of ventilation in the obstructive sleep apnea syndrome. (1981)

The recent recognition of the sleep apnea syndrome has forced a re-evaluation of the mechanism of hypercapnia and disordered respiratory control in obese patients. Thirteen obese patients with sleep apnea were studied in an attempt to relate the pattern of sleep abnormality and awake ventilatory control to the presence of chronic hypercapnia. Patients with hypercapnia and/or hypoxemia had reduced ventilatory responses to hypercapnic and hypoxic stimulation, respectively. The presence of hypercapnia, however, did not separate the patients with respect to type, duration, or frequency of apneas. The degree of awake chemical drives could not be related to the severity of the sleep apnea phenomenon. However, patients with intact ventilatory control demonstrated augmented ventilation after apneas, which may explain their eucapnic state.
Highly Active Titanium-Based Olefin Polymerization Catalysts Supported by Bidentate Phenoxyamide Ligands (2006)

Designing an integrated review sheet for an electronic textbook (2003)

In this paper, we present findings and design decisions arisen while designing a review sheet within the confines of a pre-existing digital textbook, AdaptiveBook. Through user studies, we found that instructors and students cited a lack of both context and integration as the major problems in current high-tech teaching and studying tools. Because research on electronic books indicates that metaphors "reduce users' cognitive load when navigating and acquiring information" [1], our design aims to address the lack of context and integration by creating an intuitive review sheet metaphor while leveraging the power of a digital medium.
Exploring the language modeling toolkits for Arabic text (2017)

Statistical N-grams language models (LMs) have shown to be very effective in natural language processing (NLP), particularly in automatic speech recognition (ASR) and machine translation. In fact, the successful impact of LMs promote to introduce efficient techniques as well as different types models in various linguistic applications. The LMs mainly include two types that are grammars and statistical language models that is also called N-grams. The main difference between grammars and statistical language models is that the statistical language models are based on the estimation of probabilities for words sequences while the grammars usually do not have probabilities. Despite there are many toolkits that are used to create LMs, however, this work employs two well-known language modeling toolkits with focus on the Arabic text. The implementing toolkits include the Carnegie Mellon University (CMU)-Cambridge Language Modeling Toolkit and the Cambridge University Hidden Markov Model Toolkit (HTK) language modeling toolkits. For clarification, we used a small Arabic text corpus to compute the N-grams for 1-gram, 2-gram, and 3-gram. In addition, this paper demonstrates the intermediate steps that are needed to generate the ARPA-format LMs using both toolkits.
Improving Productivity Estimates by Work Sampling (1984)

Theoretical aspects are presented to evaluate the adequacy of work sampling as a surrogate productivity measure. A 10‐week study is described in which work sampling data were gathered simultaneously with earned value information for a 10‐man, small‐bore pipefitter crew. Two forms of work sampling data were gathered that differed principally in the definition of direct work. The direct work percentages are statistically correlated to the ratio of earned to actual man‐hours, and it is shown that the Pearson product‐moment correlation coefficient could be improved by as much as 86% if the definition of direct work is restricted. The probability of a Type I statistical error is also greatly reduced. Data summarized according to 5‐ or 7‐day moving averages is found to be more reliable than daily or weekly averages. It is shown how a prediction equation could be developed. The slope of this equation suggests that rather significant changes in the earned to actual man‐hour ratio are reflected by rather small changes in direct work.
Optimization-Based Layout Design (2005)

The layout problem is of importance to ergonomists, vehicle/cockpit packaging engineers, designers of manufacturing assembly lines, designers concerned with the placement of levers, knobs, controls, etc. in the reachable workspace of a human, and also to users of digital human modeling code, where digital prototyping has become a valuable tool. This paper proposes a hybrid optimization method (gradient-based optimization and simulated annealing) to obtain the layout design. We implemented the proposed algorithm for a project at Oral-B Laboratories, where a manufacturing cell involves an operator who handles three objects, some with the left hand, others with the right hand.
MET-XAlign: A Metabolite Cross-Alignment Tool for LC/MS-Based Comparative Metabolomics (2015)

Liquid chromatography/mass spectrometry (LC/MS) metabolite profiling has been widely used in comparative metabolomics studies; however, LC/MS-based comparative metabolomics currently faces several critical challenges. One of the greatest challenges is how to effectively align metabolites across different LC/MS profiles; a single metabolite can give rise to multiple peak features, and the grouped peak features that can be used to construct a spectrum pattern of single metabolite can vary greatly between biochemical experiments and even between instrument runs. Another major challenge is that the observed retention time for a single metabolite can also be significantly affected by experimental conditions. To overcome these two key challenges, we present a novel metabolite-based alignment approach entitled MET-XAlign to align metabolites across LC/MS metabolomics profiles. MET-XAlign takes the deduced molecular mass and estimated compound retention time information that can be extracted by our previously published tool, MET-COFEA, and aligns metabolites based on this information. We demonstrate that MET-XAlign is able to cross-align metabolite compounds, either known or unknown, in LC/MS profiles not only across different samples but also across different biological experiments and different electrospray ionization modes. Therefore, our proposed metabolite-based cross-alignment approach is a great step forward and its implementation, MET-XAlign, is a very useful tool in LC/MS-based comparative metabolomics. MET-XAlign has been successfully implemented with core algorithm coding in C++, making it very efficient, and visualization interface coding in the Microsoft.NET Framework. The MET-XAlign software along with demonstrative data is freely available at http://bioinfo.noble.org/manuscript-support/met-xalign/ .

Identification of Moraxella bovis by qualitative genetic transformation and nutritional assays (1988)

Strains of Moraxella bovis were identified definitively through the combined use of a qualitative genetic transformation assay and determination of the ability of the organism under examination to grow in a defined medium (medium MB). Except for weak transformation by DNA from strains of M. lacunata, M. nonliquefaciens, and M. (Branhamella) ovis, DNA samples from all other members of the genus Moraxella failed to transform either of the two M. bovis auxotrophs used in this study.
The Price of Secure Mobile Video Streaming (2013)

The cryptographic algorithms providing unquestionable security are usually complex. From this point of view, it is reasonable that high bit rate secure live video streams require significant processing power from the end devices. To cope with the demands, there are many publications suggesting a kind of selective video encryption that reduce the burden by ciphering only a part of the video stream. As a tradeoff, the security level decreases. On the other hand, recently the retail price of the efficient hardware based cryptographic chips is dropped and devices became more and more resourceful. This is true for the mobile sector as well. In this article, based on measurements, we prove that the fully encrypted high bit rate mobile video streaming is a true possibility today, moreover there are certain scenarios where it is advised to be used. The resource barrier is no longer the processing capacity, rather the network link.
Structural Analysis of the SANT/Myb Domain of FLASH and YARP Proteins and Their Complex with the C-Terminal Fragment of NPAT by NMR Spectroscopy and Computer Simulations (2020)

FLICE-associated huge protein (FLASH), Yin Yang 1-Associated Protein-Related Protein (YARP) and Nuclear Protein, Ataxia-Telangiectasia Locus (NPAT) localize to discrete nuclear structures called histone locus bodies (HLBs) where they control various steps in histone gene expression. Near the C-terminus, FLASH and YARP contain a highly homologous domain that interacts with the C-terminal region of NPAT. Structural aspects of the FLASH-NPAT and YARP-NPAT complexes and their role in histone gene expression remain largely unknown. In this study, we used multidimensional NMR spectroscopy and <i>in silico</i> modeling to analyze the C-terminal domain in FLASH and YARP in an unbound form and in a complex with the last 31 amino acids of NPAT. Our results demonstrate that FLASH and YARP domains share the same fold of a triple α -helical bundle that resembles the DNA binding domain of Myb transcriptional factors and the SANT domain found in chromatin-modifying and remodeling complexes. The NPAT peptide contains a single α -helix that makes multiple contacts with α -helices I and III of the FLASH and YARP domains. Surprisingly, in spite of sharing a significant amino acid similarity, each domain likely binds NPAT using a unique network of interactions, yielding two distinct complexes. <i>In silico</i> modeling suggests that both complexes are structurally compatible with DNA binding, raising the possibility that they may function in identifying specific sequences within histone gene clusters, hence initiating the assembly of HLBs and regulating histone gene expression during cell cycle progression.
Exploiting Nonlinear Dynamics to Search for the Existence of Matches in a Database (2006)

We propose a method that uses nonlinear dynamics to address the task of determining the existence of a specific item in an unsorted arbitrarily large database. The scheme involves a single global operation applied simultaneously to all elements of the database and a single global monitoring threshold for verification of existence. We also show how this global threshold can be altered for identification of the existence of items with characteristics close to the searched one
