An AI-based network management system (2003)

A preliminary network management prototype that is based on the cooperation of two components is described. A network monitoring and control system (NMCS), which uses advanced database management, graphics and man/machine interface techniques, is used for data collection and status evaluation. A rule-based expert system uses its acquired expert knowledge to recommend appropriate control actions to alleviate the effects of network stresses detected by the NMCS. Preliminary results demonstrate the validity of the proposed concept.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
APPROACHES TO CONVERSATIONAL SPEECH RHYTHM: SPEECH ACTIVITY IN TWO-PERSON TELEPHONE DIALOGES (2007)

The positive linear sweep voltammograms of lead were investigated in 0.01-2.00 M aqueous HCl solutions. The results revealed the occurrence of one anodic current peak as the result of formation of a thin PbCl2 surface layer. Intensive study of the electrochemical behaviour of the lead electrode in 1.00 M HCl solution was carried out by cyclic voltammetry. The results indicated that the formation of PbCl2 is a reversible process controlled by diffusion of Cl- ions to the electrode surface. Controlling the voltammetric conditions enabled the building up of a relatively thick and porous PbCl2 layer that could resist rupture or breakdown. In addition, the electrode surface products were examined by scanning electron microscopy and X-ray diffractometry. The morphology of the as-formed PbCl2 layers showed a primitive dependence on the voltammetric conditions. X-ray diffraction analysis proved that only PbCl2 was formed on the electrode surface and no other products could be detected.
[Effect of divalent copper ions on heat denaturation of DNA]. (1978)

Using the thermal denaturation method the effect of bivalent copper of (4-10(-6)-10(-3)) M concentrations on the helix-coil transition of DNA was studied in the solution of Na+ concentrations 10(-3)-10(-1) M. Unlike the previous studies, this paper makes allowance for the effect of impurity ions present in DNA and deionized water. It has been shown that in the region of low Cu2+ and Na+ concentrations, thermal stability increases, the melting range extends and the denaturation curves become asymmetric. At concentrations more than approximately 3-10(-5) M Cu2+, melting temperature starts to fall, and the range reduces to 1-1.5 degrees at [Cu2+] greater than or equal to 2-10(-4) M. As [Cu2+] reaches these values, the denaturation curve asymmetry and melting range increase again, which is due to the inversion of the relative stability of AT- and GC-pairs. Employing experimental and phase-transition-theory data for homopolymers, the constants of Cu2+ binding with phosphates and DNA bases were calculated. The concentration dependence of the DNA denaturation parameters was shown to be governed by the superposition of binding Cu2+ with phosphates and nucleic acid bases.

The NRF2 gene variant, -653G/A, is associated with nephritis in childhood-onset systemic lupus erythematosus (2010)

Systemic lupus erythematosus (SLE) is an autoimmune disease associated with oxidative stress and characterized by chronic inflammation. Kidney malfunction, an aggressive characteristic of this disease, is not present in all affected individuals. The Nrf2-Keap1 pathway is important in protecting against oxidative stress and inflammation. Mouse models and genome-wide scans have suggested NRF2 (Nuclear factor (erythroid-derived 2)-like 2) as a candidate gene for susceptibility to SLE. We therefore investigated whether NRF2 polymorphisms are associated with childhood-onset SLE in a Mexican Mestizo population. Two single nucleotide polymorphisms (SNPs) were genotyped by TaqMan((R)) assays in 362 patients with childhood-onset SLE and 379 controls. We found no significant association between susceptibility to SLE and NRF2 polymorphisms. However, after population stratification by gender, the heterozygous genotype of the -653G/A SNP was significantly associated with nephritis in females only [OR = 1.81, CI (1.04-3.12), p = 0.032]. This association was stronger in females affected with severe nephritis [classes IV-VI; OR = 2.16, CI (1.12-4.15), p = 0.019]. Our results suggest that NRF2 is not associated with susceptibility to childhood-onset SLE, but it could confer a risk for developing kidney malfunction in SLE-affected individuals.

Epidemiological Impact of a Genital Herpes Type 2 Vaccine for Young Females (2012)

Genital Herpes, which is caused by Herpes Simplex Virus-1 or -2 (HSV-1, -2, predominantly HSV-2) is a sexually transmitted infection (STI) that causes a chronic latent infection with outbreak episodes linked to transmission. Antiviral therapies are effective in reducing viral shedding during these episodes, but are ineffective as a whole since many outbreaks are asymptomatic or have mild symptoms. Thus, the development of a vaccine for genital herpes is needed to control this disease. The question of how to implement such a vaccine program is an important one, and may be similar to the vaccination program for Human Papilloma Virus (HPV) for young females. We have developed a mathematical model to describe the epidemiology of vaccination targeting young females against HSV-2. The model population is delineated with respect to age group, sexual activity and infection status including oral infection of HSV-1, which may affect vaccine efficacy. A threshold parameter R(C), which determines the level of vaccine uptake needed to eradicate HSV-2, is found. Computer simulation shows that an adolescent-only vaccination program may be effective in eliminating HSV-2 disease, however, the success of extinction greatly depends on the level of vaccine uptake, the vaccine efficacy, the age of sexual maturity and safe sex practices. However, the time course of eradication would take many years. We also investigate the prevalence of infection in the total population and in women between 16-30 years of age before and after vaccination has been introduced, and show that the adolescent-only vaccination program can be effective in reducing disease prevalence in these populations depending on the level of vaccine uptake and vaccine efficacy. This will also result in a decrease of maternal-fetal transmission of HSV-2 infection. Another important, if commonsense, conclusion is that vaccination of some females reduces infection in men, which then reduces infection in women.
A General Approach to Online Sensor Calibration for Navigation using Factor Graphs (2013)

We present a general method for online sensor calibration using factor graphs, which can be applied to a wide range of sensors and parameter types. Our approach refines a particular sensor’s calibration parameters using all sensors’ measurements recorded in a small period of time at the beginning of a navigation mission, and then uses the refined parameters in the rest of the mission. The parameter estimation module is implemented in our twotier navigation system which comprises a low-latency Hierarchical Multi-Rate Filter (HMF) and a high-quality Trajectory Smoother/Mapper (TSM). HMF and TSM run in parallel to provide a low-latency and accurate navigation solution. TSM includes the parameter estimation sub-module, which refines the sensor calibration parameters. We present methods for calibrating four types of parameters that are often encountered in a navigation system: wind velocity, compass bias, time offset between system’s clock and camera’s clock, and step size of pedestrians. In addition, we validated our proposed calibration method using both real aerial and ground data.
Stress distribution in optical-fiber ribbons (1997)

Previous results indicate that fibers in ribbons are sometimes affected by systematic birefringence superimposed on the random one, their relative weights depending on fiber position in the ribbon. We report new theoretical and experimental results on stress distribution in ribbons, which is shown to depend on thermal and mechanical properties of the common coating. Numerical simulations are based on the theory of elasticity and the finite-element method (FEM). Polarization dispersion measurements vs. temperature match very well with numerical results, and indicate that central fibers in the ribbon exhibit significantly larger birefringence than lateral ones.

Differential Evaluation of Excisional Non-occluded Wound Healing in db/db Mice (2009)

The full-thickness wound in the genetically diabetic (db/db) mouse is a commonly used model of impaired wound healing. We investigated delayed healing of non-occluded, excisional, full-thickness, dermal wounds in db/db mice in comparison to their normal littermate controls and refined methods for monitoring skin wound re-epithelialization, contraction, granulation tissue formation, and inflammation. We have confirmed with a computer-assisted planimetry method the results of previous studies showing that healing of non-occluded full excision wounds in db/db mice does not occur by contraction as much as in healthy mice. In addition, we have developed separate histological methods for the assessment of re-epithelialization, contraction, granulation tissue (mature, immature, fibrosis), and inflammation (lipogranulomas, secondary, nonspecific). Using a new approach to histological assessment, we have shown that wound closure in db/db mice is delayed owing to: (1) delayed granulation tissue maturation; (2) ''laced,'' widely distributed granulation tissue around fat lobules; and (3) obstruction by lipogranulomas, whereas the rate of re-epithelialization seems to be the same as in C57Bl/6 mice. This methodology should permit a more precise differentiation of effects of novel therapeutic agents on the wound healing process in db/db mice.
Architecture of the IBM System/360 (1964)

The architecture of the newly announced IBM System/360 features four innovations: 1. An approach to storage which permits and exploits very large capacities, hierarchies of speeds, read-only storage for microprogram control, flexible storage protection, and simple program relocation. 2. An input/output system offering new degrees of concurrent operation, compatible channel operation, data rates approaching 5,000,000 characters/second, integrated design of hardware and software, a new low-cost, multiple-channel package sharing main-frame hardware, new provisions for device status information, and a standard channel interface between central processing unit and input/output devices. 3. A truly general-purpose machine organization offering new supervisor facilities, powerful logical processing operations, and a wide variety of data formats. 4. Strict upward and downward machine-language compatibility over a line of six models having a performance range factor of 50. This paper discusses in detail the objectives of the design and the rationale for the main features of the architecture. Emphasis is given to the problems raised by the need for compatibility among central processing units of various size and by the conflicting demands of commercial, scientific, real-time, and logical information processing. A tabular summary of the architecture is shown in the Appendices.
Numerical Investigation on the Fatigue Behavior of the Multi-Planar Tubular DX-Joint under Combined Loads (2014)

The stress concentration factors (SCFs) is used in the fatigue design for calculating hot-spot stress. However a major issue can be noted that the majority of research results are focused on the SCF distribution of uni-planar tubular joints subjected to the single basic load. By aiming to find the solution of this problem, the distribution of SCFs at the weld toe of a multi-planar tubular DX-joint which is subjected to the two set of the balanced combined loading components at the end of in-plane braces is studied by the finite element method. Thus it is concluded that for the axial plus in-plane bending load case, hot-spot stress location varies between saddle and crown position; while the location is invariably at the saddle position under combined axial plus out-of-plane bending loads. At last the API RP2A equation for predicting hot-spot stress is used for comparison with the finite element analysis results. Meanwhile the distribution of SCFs is also provided, that information indicates the-hot spot location along the weld toe affects the crack initiation.
Mid-facial anthropometry in second-trimester fetuses with trisomy 21: a three-dimensional ultrasound study (2006)

The nasal bones are present in the majority of fetuses with trisomy 21 in the second trimester. This group of fetuses has a characteristic mid-facial anthropometry (wider maxillary angle) that can be assessed by means of 3D ultrasonography.
Features and a model for icon morphological transformation (2002)

The study proposes several criteria and a system model for morphological construction and transformation of icons. From this point of view, several important concepts, such as meta/actual-use of icons; icon homonyms/synonyms; local/global context; location sensitivity; icon orthogonality/consistency; degree of fusion and combination adequacy; or top-down/bottom-up transformation are discussed. Based on this discussion, a general framework of iconic systems is proposed. In this model, icons are system independent objects, and are morphologically (e.g., incorporation) transformed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Return on Investment in Social Media--Does the Hype Pay Off? Towards an Assessment of the Profitability of Social Media in Organizations (2012)

Since the popularity of customer-centered social media has increased substantially during the last few years, firms have been eager to profit from this trend. Given the uncertain payoffs and constraints on human resources, however, there is as yet no decision tool to help decide on social media implementation. Our paper addresses this gap by establishing a framework for assessing the profitability of customer-centered social media initiatives in organizations. We first outline the importance of customer-centered social media and demonstrate the research gap. We thereafter analyze the common characteristics of customer-centered social media initiatives and identify their main success drivers. We then combine the current knowledge on social media success drivers with the return on investment (ROI) research stream by proposing a balanced framework towards measuring the ROI of customer-centered social media projects. The proposed framework balances a project's high uncertainty with managers' need for hard facts. In a first step towards the framework's validation, we use 12 empirical examples to showcase the proposed framework's application.
Common Channel Interoffice Signaling: History and Description of a New Signaling System (1978)

A new interoffice signaling system known as the Common Channel Interoffice Signaling System (CCIS) has been introduced into the Bell System's DDD toll network. It represents a major step forward in signaling systems by providing high speed data links between processors of stored-program-controlled switching offices to carry all signaling and network control information, completely independent of the communication paths used by customers. As CCIS implementation proceeds it will have an expanding and significant impact on the DDD network system performance due to improved speed of signaling and provision of signals to provide a multitude of new network and customer services. The history of common channel signaling is traced from early mechanical implementation to use of present-day technological advances. The fundamental concepts, basic features, signal formats and system operation are described.
Pharmacokinetics and safety of deramciclane during multiple oral dosing. (1999)

In conclusion, the pharmacokinetics of deramciclane is linear over the dose range of 10 - 60 mg at steady-state. The slight non-linearity within the dose levels during repeated administration of seven days was regarded as clinically irrelevant. Deramciclane was safe and well tolerated up to doses of 60 mg b.i.d. for seven days.

Rubbing Against Blood Clots Using Helical Robots: Modeling and In Vitro Experimental Validation (2017)

The risk of side effects from thrombolytic agents can be minimized by using smaller doses, assisted by mechanical rubbing against blood clots using helical robots. Quantifying this observation, we study the influence of rubbing against clots on their removal rate in vitro. First, we present a hydrodynamic model of the helical robot based on the resistive-force theory to investigate the rubbing behavior of the clots using robot driven by two rotating dipole fields. Second, we experimentally evaluate the influence of the rubbing on the removal rate of the blood clots. Not only do we find that the removal rate of mechanical rubbing (-0.56 ± 0.27 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> /min) is approximately three times greater than the dissolution rate of chemical lysis using streptokinase (-0.17 ± 0.032 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> /min), but we also show that this removal rate can be controlled via the rubbing speed of the robot.
Electrical and pressure losses in a magnetohydrodynamic channel due to end current loops (1962)

End electrical and pressure losses are calculated for d-c magnetohydrodynamic (MHD) power generators, accelerators, or induction pumps having a geometry of a rectangular parallelopiped with the electric field, magnetic field, and fluid flow mutually perpendicular. For an MHD generator, having a cubic geometry, the maximum conversion efficiency is only 29%. This can be improved by increasing the length of the generator, inserting vanes, and extending the magnetic field, so that efficiencies of 90% should be attainable.
Storybase: Towards Building a Knowledge Base for News Events (2015)

To better organize and understand online news information, we propose Storybase 1 , a knowledge base for news events that builds upon Wikipedia current events and daily Web news. It first constructs stories and their timelines based on Wikipedia current events and then detects and links daily news to enrich those Wikipedia stories with more comprehensive events. We encode events and develop efficient event clustering and chaining techniques in an event space. We demonstrate Storybase with a news events search engine that helps find historical and ongoing news stories and inspect their dynamic timelines.
Multispectral Image Co-occurrence Matrix Analysis for Poultry Carcasses Inspection (1996)

Textural feature analysis of multispectral images containing visible/near-infrared (NIR) wavelengths based on co-occurrence matrices was demonstrated as feasible for discriminating abnormal from normal poultry carcasses at a wavelength of 542 nm. Statistical regression models and neural network models were used to develop classifiers. The results showed that the accuracy for the separation of normal carcasses was 94.4% when the statistical regression model was used. Specifically, the classification was perfect when the normal carcasses were separated from the septicemic and cadaver carcasses. However, for separating condemned carcasses between septicemic and cadaver, the accuracy was 96% for septicemic and 82.7% for cadaver cases. When neural network models were employed to classify poultry carcasses into three classes (normal, septicemic, and cadaver), the accuracy of classification were 88.9% for normal, 92% for septicemic, and 82.6% for cadaver cases. Whereas, the separation of the neural network classifier performed without error for two classes (normal vs. abnormal) classification.
