Function Meets Style: Insights From Emotion Theory Applied to HRI (2004)

As robot designers, we tend to emphasize the cognitive aspect of intelligence when designing robot architectures while viewing the affective aspect with skepticism. However, scientific studies continue to reveal the deeply intertwined and complementary roles that cognition and emotion play in intelligent decision-making, planning, learning, attention, communication, social interaction, memory, and more. Such findings provide valuable insights and lessons for the design of autonomous robots that must operate in complex and uncertain environments and perform in cooperation with people. This paper presents a concrete implementation of how these insights have guided our work, focusing on the design of sociable autonomous robots that interact with people as capable partners.
Combined Cycle Performance Deterioration Analysis (2002)

Combined\ncycles are subject to degradations and hence performance deterioration.\nAccording to the author's survey nothing was found in the open literature on this\nsubject. Therefore, it was anticipated that it would be of great achievement if a tool for\nanalysing and diagnosing the deterioration of combined cycle could be produced. So\nthis thesis\npresents a procedure for combined cycle performance analysis and fault\ndiagnostic by way of simulation.\nl order to\naccomplish this task successfully it was necessary to developed two\npieces of software. These are STEAMOMATCH for steam cycle performance\ndeterioration\nanalysis, and GOTRESS for GPA of any system. STEAMOMATCH, which\nis built on the basics of combined cycle thermodynamics, can simulate up to three levels\nof\npressure with reheat. On the other hand GOTRESS uses a Gas Path Analysis\ntechnique that enables the user the choice of conducting either linear or non-linear GPA\nat the same time. I both cases single or multiple fault can be diagnosed. GOTRESS\nwas built in such a\nway that it makes it a generalised code that can be used not only for\ncombined\ncycle but to diagnose a wide range of power cycle plants.\nThe deterioration simulation results of the gas turbine power plant showed that the\nisentropic efficiency deterioration of the turbine unit has the uppermost sever effect on\noverall\ngas turbine power output and thermal efficiency. This is also the case with\nsteam turbine\n(bottoming) cycle power and Rankine efficiency. Also, the simulation\nresults obtained showed that the relationship between the gas turbine size and its\nperformance deterioration is almost constant, i.e. performance deterioration follows the\nplant's size. Among the two major gas turbine parameters that affects the steam\nbottoming cycle performance of a CCGT power plant, the gas turbine exhaust\ntemperature has a predominant effect on steam cycle efficiency over the exhaust mass\nflow.' As a\ngeneral result, the obtained simulation results showed that the behaviour of\nCCGT\npower plant performance is more affected by gas turbine cycle conditions than\nby steam turbine cycle conditions. The obtained results showed that GPA can be\nsuccessfully applied to either gas turbine cycle, steam turbine cycle, or the combination\nof the two in a form of combined cycle. The GPA diagnostic results obtained showed\nthat it would be\npossible to detect some faults that might occur within the gas turbine\nthat is a\npart of a combined cycle power plant by monitoring the dependent parameters\nof the steam turbine (bottoming) cycle such as live steam pressure and temperature and\nsteam turbine\npower. In contrast, it would not been possible to detect the problems\n(implanted faults) that might occur within the steam turbine by monitoring the\ndependent parameters of the gas turbine unit.
<i>In Vivo</i> Brain Water Determination by <i>T</i><sub>1</sub> Measurements: Effect of Total Water Content, Hydration Fraction, and Field Strength (1991)

This work is concerned with the accurate quantification of brain water content under routine clinical conditions. Gelatin solutions of varying water content are first employed as a model of an edematous brain and longitudinal relaxation measurements are performed at proton Larmor frequencies of 5, 41, 63, and 100 MHz. These are followed with in vivo measurements in an experimental animal model of brain edema at 41 MHz. The results underscore the dominant role of total water content W in the relaxation process and verify the expected linearity between 1/T1 and 1/W. A scheme is presented and experimentally verified at 41 MHz for deducing the exact relationship of 1/T1 vs 1/W at any frequency. Knowledge of this relationship along with precise measurements of 1/T1 at a given field strength permits quantitative in vivo measures of brain water content to be obtained with a precision of about 0.01. It is concluded that routine, accurate, and noninvasive brain water measurements are possible by magnetic resonance imaging in a clinical environment.
Myomectomy during Caesarean Section: Safety and Feasibility of the Procedure (2016)

Objective (s): Aim of the study was to evaluate the safety and feasibility of myomectomy during cesarean section.Materials and methods: This prospective observational study was carried out in a private setting at Dhaka city from January 2006 to June 2015. Forty five (45) women with fibroid uterus with pregnancy who needed caesarean section were the target population for this study. Myomectomy was done during caesarean section. Main outcome measures were: difficulty of myomectomy and caesarean section, time needed for operation, per-operative complications, need for blood transfusion, postoperative complications and duration of hospital stay.Results: During the study period total 45 women were found who had pregnancy with myoma and needed caesarean section for various indications. Twenty nine (64.4%) women were of age 26-35 years, 30 (66.7%) were para 0 and in 37 (82%) cases were term pregnancy. In forty one (91.1%) cases myomas were diagnosed preoperatively. Twenty five (55.6%) women had multiple myomas. Commonest site of myoma was body of the uterus (82.2%) and commonest type was intramural (75.6%). Thirty (66.7%) women had myoma of less than 5cm in size. In forty two (93.3%) cases myomectomy was done after delivery of the baby. Myomectomy was successful in all 45 (100%) cases. In thirty (80%) cases caesarean myomectomy was completed within 1 hour. Thirty seven (82.2%) women did not need blood transfusion and thirty eight (84.4%) women had no postoperative complication. Other had minor complications. Forty one (90.1%) women were discharged from hospital within 72 hours of operations.Conclusion: Myomectomy during cesarean section is a safe procedure and it is feasible in almost all cases. Though large scale RCT is needed before giving final conclusion it is not far away when myomectomy during cesarean section will be norm discarding the traditional view of not touching the myoma in pregnancyBangladesh J Obstet Gynaecol, 2015; Vol. 30(1) : 10-14
New endemic West Nile virus lineage 1a in northern Italy, July 2012 (2012)

We report here the first blood donation positive for West Nile virus (WNV) by nucleic acid amplification testing collected in north-eastern Italy in July 2012.Partial sequencing of the WNV RNA demonstrated identity with a WNV lineage 1a genome identified in the same area in 2011 and divergence from the strain responsible for the outbreak in northern Italy in 2008–09. These data indicate that WNV activity in northern Italy is occurring earlier than expected and that different WNV strains are circulating.
A new efficient algorithm to compute the two-dimensional discrete Fourier transform (1988)

An algorithm is presented for computation of the two-dimensional discrete Fourier transform (DFT). The algorithm is based on geometric properties of the integers and exhibits symmetry and simplicity of realization. Only one-dimensional transformation of the input data is required. The transformations are independent; hence, parallel processing is feasible. It is shown that the number of distinct N-point DFTs needed to calculate N*N-point two-dimensional DFTs is equal to the number of linear congruences spanning the N*N grid. Examples for N=3, N=4, and N=10 are presented. A short APL code illustrating the algorithm is given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimization of fault indicators placement with dispersed generation insertion (2005)

This paper presents an optimization method of fault indicator placement by genetic algorithms. Requirements such as the network structure with switchgear system, reliability factor, economic parameters and fault localization by switchgear can be taken into account in an objective function to minimize. The influence of dispersed generation, inserted in the distribution network, on the fault indicator placement is also carried out. The tool created provides help to select the optimal fault indicator placement in the network following different objectives.
A novel approach to identify driver genes involved in androgen-independent prostate cancer (2014)

Our approach has proven effective for use in PCa, identifying a known prostate cancer gene, PTRF, and also several genes not previously associated with prostate cancer. The replication-incompetent shuttle vector approach has broad potential applications for cancer gene discovery, and for interrogating diverse biological and disease processes.
Moving obstacle detection using residual error of FOE estimation (2002)

The paper presents a simple moving obstacle detection method which used the residual error calculated in uses of focus of expansion (FOE) estimation. Method can be applied to many industrial tasks such as an intelligent machine surveillance system or an obstacle detection system for an autonomous vehicle system. First, the optical flow field is extracted from sequence of dynamic imaged captured by a fixed camera on a moving observer. Next, the FOE is estimated in local image regions. Its residual error is first calculated in the region. An image region corresponding to the block is added with the residual error. This process is repeated by sliding and adding for the local region, and changing the size of the local region. Finally, regions which have high residual error values are detected as candidate regions of moving obstacles. Experimental results using real outdoor scenes show the effectiveness of the proposed method.
An FPGA-based floating-point processor array supporting a high-precision dot product (2006)

This note reports on the design of a pipelined floating point processor on a Spartan-III FPGA. It is implemented as a coprocessor to a novel, universal controller for pipelined data path designs that provides a high-level API and compiler support for general FPGA applications. The controller adds multithreading and networking to the processor design, and the option of SIMD processing. The complexity issue of high precision floating point in an FPGA implementation is taken care of by efficiently implementing a recent algorithm of Rump that computes the dot product of two vectors at the same level of precision as a double precision processor yet using single precision operations only including a few non-standard primitives. For these special operations, our FPGA based processor actually outperforms hardwired floating-point DSP chips performing them in software. Through the inclusion of sequential control and networking our design provides a realistic estimate of the floating point system performance of FPGA in standard applications
HYDROXYLATION OF BENZENE WITH HYDROGEN PEROXIDE BY THE USE OF HYDROPHOBIC CATECHOLS AND Fe3+ COMPLEXES AS THE CATALYST (1981)

Abstract Hydroxylation of benzene with H2O2 was carried out in the Presence of a variety of catechols and Fe3+ in a benzene–H2O biphase system. The hydrophobic catechols were found far more effective as the catalyst than the hydrophilic ones.
Migration using the shortest-path method (1994)

Abstract The shortest-path method for the calculation of seismic rays and traveltimes in complicated media is compared with two methods for traveltime calculation that are based on a finite-difference solution of the eikonal equation, namely the algorithm of Vidale and a modification by Gray of the algorithm of van Trier and Symes. This comparison consists of two parts: first, the performance of the three algorithms in forward modeling is tested, and second, their application in Kirchhoff migration is demonstrated. The comparison of the forward modeling shows a very close resemblance between the shortest-path method and the eikonal equation solver of Vidale, but quite large differences with Gray's version, which was developed exclusively for application to migration and therefore favors speed at the cost of a possible loss of accuracy. Surprisingly, application of the three methods to the migration of the Marmousi data set shows differences only in small details. The flexibility of the shortest path method allows for application in exploding reflector migration; each reflector can be reconstructed from zero-offset traveltime data by only one forward calculation. Investigation of the effect of smoothing of the slowness model shows that a moderate amount of smoothing delays the traveltimes by about 1 to 2 percent but has no visible effect on the migration results.
Translation Invariant Combined Denoising Algorithm (2005)

The paper develops a method for denoising images corrupted with additive white Gaussian noise (AWGN). The noise degrades the image quality and makes the interpretation, analysis and segmentation of images harder. The discrete curvelet transform is a new image representation approach that codes image edges more efficiently than the wavelet transform. On the other hand, the wavelet transform codes homogeneous areas better than the curvelet transform. A translation invariant combined denoising algorithm (TICDA) is proposed. The algorithm is implemented by combining the undecimated discrete wavelet transform (UDWT) and the translation invariant discrete curvelet transform (TIDCT). The AWGN image is then denoised by letting the TICDA solve an l/sub 1/ optimization problem.
Epidemiology of sexually transmitted diseases: the global picture. (1990)

Sexually transmitted diseases (STD) are now the commonest group of notifiable infectious diseases in most countries, particularly in the age group of 15 to 50 years and in infants. Their control is important considering the high incidence of acute infections, complications and sequelae, their socioeconomic impact, and their role in increasing transmission of the human immunodeficiency virus (HIV). The worldwide incidence of major bacterial and viral STD is estimated at over 125 million cases yearly. STD are hyperendemic in many developing countries. In industrialized countries, the bacterial STD (syphilis, gonorrhoea, chancroid) declined from the peak during the Second World War till up to the late fifties, then increased during the sixties and early seventies, and they have been decreasing again from the late seventies till the present. In the industrialized world, diseases due to Chlamydia trachomatis, genital herpes virus, human papillomaviruses and human immunodeficiency virus are now more important than the classical bacterial ones; both groups remain major health problems in most developing countries. Infection rates are similar in both women and men, but women and infants bear the major burden of complications and serious sequelae. Infertility and ectopic pregnancies are often a consequence of pelvic inflammatory disease, and are preventable. Sexually transmitted diseases in pregnant women can result in prematurity, stillbirth and neonatal infections. In many areas 1-5% of newborns are at risk of gonococcal ophthalmia neonatorum, a blinding disease; congenital syphilis causes up to 25% of perinatal mortality. Genital and anal cancers (especially cervical cancer) are associated with viral sexually transmitted diseases (genital human papillomavirus and herpes virus infections). Urethral stricture and infertility are frequent sequelae in men.
Preliminary pathologic findings in bullfrog (Rana catesbiana) and green frog (Rana clamitans) larvae collected from farm ponds in Tennessee. (2006)

Amphibian populations are declining worldwide, with anthropogenic stressors as a common mechanism among leading hypotheses. An anthropogenic stressor that has not been explored in detail is the influence of cattle grazing in farm ponds. In particular, cattle may introduce pathogens or change the aquatic environment such that resident larval amphibians become stressed and immunity is compromised. Amphibians also may function as reservoirs for pathogens (e.g., Cryptosporidium parvum, Leptospira spp., Salmonella spp., Escherichia coli, Mycobacterium paratuberculosis and Listeria monocytogens) that are associated with cattle and could be ultimately transferred to humans as a foodborne illness. Thus, our objective was to compare pathogen prevalence in bullfrog and green frog tadpoles inhabiting farm ponds with and without cattle access. We collected 101 bullfrog and 80 green frog tadpoles from eight farm ponds in February, June, and October 2005, and compared prevalence between cattle-access treatments. Iridovirus, Aeromonas hydrophila, Pseudomonas spp., Corynebacterium spp. and Mycobacterium spp. were isolated from tadpoles in both treatment groups. All individuals were negative for cattle-associated pathogens. These findings suggest that cattle may not influence pathogen prevalence in amphibians; however, our results may be a consequence of uninfected cattle or relatively low grazing intensity in our cattle-access ponds. A more extensive and prolonged study is planned involving controlled experimental infections of tadpoles with pathogens of concern to amphibians and humans.
Simplistic dynamic image based rendering (2003)

We present a very inexpensive way of creating dynamic image-based renderings of digitally recorded, photo realistic, real-life objects. Together with computer vision algorithms, the recorded person is visualized using the Relief Texture Mapping algorithm [Oliveira et al. 2000]. This mapping technique requires depth information for all texels representing the recorded object from all recorded views. By using two digital video cameras, the dynamic object is recorded in stereo in different views to cover its whole volume. As the depth information from the separate views is generated by stereo correlation, it is used together with the recorded video as relief textures on a pre-defined bounding box and morphed into a three dimensional representation by justifying the known depth disparities.
Proteinases in rheumatoid arthritis. (1992)

The role of proteinases in the extracellular breakdown of the connective tissue matrix during disease processes is outlined. Focussing on the matrix metalloproteinases, we present an overview of the mechanisms regulating their activity. Methods of assessing their role in disease processes is exemplified by new data on stromelysin activity in remodelling joint tissues in both model systems and human disease.
Hypoxia-inducible factor-1α polymorphisms and TSC1/2 mutations are complementary in head and neck cancers (2006)

Dysregulation of the TSC1/TSC2 complex by mutation compliments HIF-1alpha polymorphisms in the expression of HIF-1alpha in SCC of the head and neck, and may provide biomarkers to predict responses to specific therapies and overall disease prognosis.
Differential immunohistochemical and biological profile of squamous cell carcinoma of the breast. (2007)

The expression profile of SCC of the breast was markedly different from that of IDC. A typical "basal-like" phenotype was displayed that may explain part of their behaviour and justify specific therapeutic approaches. HPV infection was not a leading oncogenic event in SCC of the breast.
Validation of a polymerase chain reaction/restriction enzyme analysis method for species identification of thermophilic campylobacters isolated from domestic and wild animals (2002)

Routinely used phenotypic tests often resulted in unreliable identifications, requiring additional testing. The PCR/REA, however, gave unequivocal results and was considered useful for the routine identification of thermophilic campylobacters from different animals.
Packet Switching in Radio Channels: New Conflict-Free Multiple Access Schemes (1980)

We study new access schemes for a population of geographically distributed data users who communicate with each other and/or with a central station over a multiple-access broadcast ground radio packet-switching channel. We introduce and analyze alternating priorities (AP), round robin (RR), and random order (RO) as new conflict-free methods for multiplexing buffered users without control from a central station. These methods are effective when the number of users is not too large; as the number grows, a large overhead leads to a performance degradation. To reduce this degradation, we consider a natural extension of AP, called minislotted alternating priorities (MSAP) which reduces the overhead and is superior to fixed assignment, polling, and known random access schemes under heavy traffic conditions. At light input loads, only random access schemes outperform MSAP when we have a large population of users. In addition, and of major importance, is the fact that MSAP does not require control from a central station.
Switchable Proline Derivatives: Tuning the Conformational Stability of the Collagen Triple Helix by pH Changes (2014)

(4S)-Aminoproline is introduced as a pH-sensitive probe for tuning the conformational properties of peptides and proteins. The pH-triggered flip of the ring puckering and the formation/release of a transannular H bond were used to switch the formation of collagen triple helices on and off reversibly.
DNase I Increases the Rate Constant of Depolymerization at the Pointed (-) End of Actin Filaments (1994)

We show here that DNase is distinguished from other known actin-binding proteins by its unique ability to increase the depolymerization rate constant of actin at the pointed filament end, thereby speeding up depolymerization of filaments capped at their barbed ends. This action requires relatively high DNase concentrations, 3 orders of magnitude higher than those needed to block elongation, although 10 times lower than those needed for DNase binding to the side of the filament. We propose that a high DNase concentrations, steric interference between the two DNase molecules, bound to the ends of both strands of the two-start actin helix, destabilizes actin binding to the filament.
The effect of lead on male fertility: A time to pregnancy (TTP) study (2000)

It is not easy to assert or to deny the effect of inorganic lead on male fecundity, quantitatively estimated by TTP, with the data available for this study. In fact, while the general data seem to exclude effects of Pb on male fecundability a more detailed analysis suggests an unfavorable effect at relatively high levels of exposure but some confounding attributable to personal and social conditions of the workers cannot be ruled out. Further investigations with a better control of confounding are needed.
