Reaching out to the cell phone with Jini (2003)

Jini has made considerable inroads as an enterprise computing platform, but it hasn't fulfilled its promise as an ubiquitous computing platform for thin clients. A roadblock has been that full participation in a Jini community requires devices to support a fully capable Java virtual machine, something that is a challenge for mobile devices (e.g., cellphones). The Jini Surrogate specification aims to provide a service gateway that enables limited Java devices to hook into a Jini network, eliminating the need for Jini on the device. The paper describes the Jini Surrogate Architecture, its benefits in enabling wireless access to Jini services, and the implementation and performance issues uncovered in implementing surrogate-based services. The paper discusses several application architectures that can leverage the surrogate approach. These include exporting enterprise services from the wired Internet to the wireless Internet, and enabling a thin-client mobile agent platform that implements migratory services. These application architectures are being further explored as part of the Arches project.
Pre-repeat selective-repeat ARQ in fading channel (2002)

A new selective-repeat (SR) ARQ scheme using the pre-repeat (PR) technique is proposed. The proposed scheme is efficient in digital cordless-phone systems employing TDMA-TDD under slow fading environments. Because fading affects both up-link channel and down-link channel simultaneously, the occurrence of error in the up-link channel is closely correlated with that in the down-link channel. This characteristic can be applied to predict errors in transmitted data by observing received signal. In this paper, throughput efficiency of the proposed scheme is investigated by computer simulation, and is compared with conventional SR-ARQ. It indicates that the proposed scheme is advantageous to transmission with a long round-trip delay.
The Crystal Structure of an Avian IgY-Fc Fragment Reveals Conservation with both Mammalian IgG and IgE (2008)

Avian IgY is closely related to an ancestor of both mammalian IgG and IgE and thus provides insights into the evolution of antibody structure and function. A recombinant fragment of IgY-Fc consisting of a dimer of the Cupsilon3 and Cupsilon4 domains, Fcupsilon3-4, was expressed and crystallized and its X-ray structure determined to 1.75 A resolution. Fcupsilon3-4 is the only nonmammalian Fc fragment structure determined to date and provides the first structural evidence for an ancient origin of antibody architecture. The Fcupsilon3-4 structure reveals features common to both IgE-Fc and IgG-Fc, and the implications for IgY binding to its receptor are discussed.
Temperature Dependence of Mechanical and Dielectric Relaxation in <i>cis</i>-1,4-Polyisoprene (1998)

The linear viscoelastic properties of 1,4-polyisoprene (PI; MW = 504 000) were measured by combined mechanical and dielectric spectroscopies. For local segmental motion, the respective mechanical and dielectric relaxation times, although differing substantially in magnitude, have identical temperature dependencies. The shape of the segmental relaxation function itself was sensitive to temperature. The data, obtained over a 160 degree range of temperatures, could be reduced to yield ostensibly satisfactory master curves; however, detailed analysis reveals the usual breakdown of time−temperature superpositioning in the glass transition zone. Given the near equivalence of the respective breadths of its terminal and segmental dispersions, thermorheological complexity in PI is unanticipated by theory. In the plateau zone, the mechanical spectrum of PI exhibits power law behavior, with an exponent (0.21) close to a proposed universal value.
Contour Motion Estimation for Asynchronous Event-Driven Cameras (2014)

This paper compares image motion estimation with asynchronous event-based cameras to Computer Vision approaches using as input frame-based video sequences. Since dynamic events are triggered at significant intensity changes, which often are at the border of objects, we refer to the event-based image motion as “contour motion.” Algorithms are presented for the estimation of accurate contour motion from local spatio-temporal information for two camera models: the dynamic vision sensor (DVS), which asynchronously records temporal changes of the luminance, and a family of new sensors which combine DVS data with intensity signals. These algorithms take advantage of the high temporal resolution of the DVS and achieve robustness using a multiresolution scheme in time. It is shown that, because of the coupling of velocity and luminance information in the event distribution, the image motion estimation problem becomes much easier with the new sensors which provide both events and image intensity than with the DVS alone. Experiments on synthesized data from computer vision benchmarks show that our algorithm on combined data outperforms computer vision methods in accuracy and can achieve real-time performance, and experiments on real data confirm the feasibility of the approach. Given that current image motion (or so-called optic flow) methods cannot estimate well at object boundaries, the approach presented here could be used complementary to optic flow techniques, and can provide new avenues for computer vision motion research.
Quantum dot intermediate band solar cell material systems with negligible valence band offsets (2005)

In this paper, material triads (quantum-dot/barrier/substrate) are presented that may implement quantum dot intermediate band solar cells with conversion efficiencies greater than 60%. Triads whose barrier material and substrate material are lattice-matched are presented. In addition, triads are presented with the lattice constant of the substrate in-between the lattice constant of the barrier and the lattice constant of the quantum dot. The latter case provides triads that may remove strain during epitaxial growth.
Study on the effect of object to camera distance on polynomial expansion coefficients in barrel distortion correction (2003)

Videoendoscopy is becoming increasingly popular in surgical procedures. Wide-angle lenses are commonly employed in such applications for enhanced viewing capability. However, images captured with these lenses suffer from barrel distortion. 2D distortion correction for images captured with wide-angle lenses has been widely investigated in clinical applications, it is necessary to incorporate correction techniques that are independent of the distance from the object to the camera lens. In this paper, we prove that for a wide-angle camera lens with fixed focal length, the distortion correction coefficients remain the same for distances within the minimum and maximum range (depth of field). Experiments have also been performed to verify this.
Antiarrhythmic drug-induced side effects: a prospective survey of 300 patients. (1996)

The purpose of this study was to define the characteristics and the frequency of antiarrhythmic drug-induced side effects. All patients referred for cardiological consultation and treated with antiarrhythmic drugs between April 1992 and October 1993 were prospectively investigated. 300 patients were included in the study: 41 (13.6 per cent) had drug-induced side effects, nine of which were serious: 5 proarrhythmic effects, 1 pulmonary fibrosis, 1 peripheral neuropathy, and 2 acute cardiac failure. Side effects led to discontinuation of treatment in 26 cases (7.6 per cent). Statistical analysis showed that side effects occurred more commonly with disopyramide (46.1 per cent, P < 0.01) or propafenone (41.7 per cent, P < 0.05) and less frequently with sotalol (2 per cent, P < 0.01) than with the other drugs (flecainide 20 per cent; amiodarone 16.4 per cent; cibenzoline 4.8 per cent; hydroquinidine 4.3 per cent). Side effects were more common on bitherapy (39 per cent) than on monotherapy (13 per cent) in general and in the amiodarone-treated group in particular. In conclusion, side effects of antiarrhythmic drugs involved 1/6 patients overall and led to discontinuation of treatment in 1/14. The frequency of proarrhythmias (1.1 per cent) was lower than previously reported, suggesting that recently published clinical trials have modified the prescription habits.

Modeling belief and preference in multi-agent support systems (1996)

In "multi-agent" systems such as groups, problem solving is an intentional process that causes individual agents to pursue goals, commit to action and adopt beliefs, as well as seek and manipulate related knowledge and information. Because human agents can engage in such action independently, conflicting agent-centric preferences for "products" and "processes" emerge in group problem solving. Although such capabilities have been speculated for machine agents, they have been given only rudimentary conceptual definition and, hence, are far from practical for application to multi-agent support systems. Yet, the same problems of preference seem likely. This paper outlines a conceptual model and supporting logic for intentional processes in multi-agent support systems and then explores agent preferences for problem-solving strategies in more depth.
Phage Peptide Libraries As a Source of Targeted Ligands (2016)

One of the dominant trends in modern pharmacology is the creation of drugs that act directly on the lesion focus and have minimal toxicity on healthy tissues and organs. This problem is particularly acute in relation to oncologic diseases. Short tissue- and organ-specific peptides capable of delivering drugs to the affected organ or tissue are considered promising targeted agents that can be used in the diagnosis and therapy of diseases, including cancer. The review discusses in detail the technology of phage display as a method for obtaining specific targeted peptide agents and offers examples of their use in diagnostic and clinical practice.
C–H Bond Strengths and Acidities in Aromatic Systems: Effects of Nitrogen Incorporation in Mono-, Di-, and Triazines (2012)

The negative ion chemistry of five azine molecules has been investigated using the combined experimental techniques of negative ion photoelectron spectroscopy to obtain electron affinities (EA) and tandem flowing afterglow-selected ion tube (FA-SIFT) mass spectrometry to obtain deprotonation enthalpies (Δ(acid)H(298)). The measured Δ(acid)H(298) for the most acidic site of each azine species is combined with the EA of the corresponding radical in a thermochemical cycle to determine the corresponding C-H bond dissociation energy (BDE). The site-specific C-H BDE values of pyridine, 1,2-diazine, 1,3-diazine, 1,4-diazine, and 1,3,5-triazine are 110.4 ± 2.0, 111.3 ± 0.7, 113.4 ± 0.7, 107.5 ± 0.4, and 107.8 ± 0.7 kcal mol(-1), respectively. The application of complementary experimental methods, along with quantum chemical calculations, to a series of nitrogen-substituted azines sheds light on the influence of nitrogen atom substitution on the strength of C-H bonds in six-membered rings.
Analysis of Three Trusted Friends' Vulnerability in Facebook (2013)

With about 1 billion users, Facebook nowadays is the most popular and famous social networking site (SNS) around the globe. It is one of the Internet's biggest success stories. Facebook gets hundreds of new users every day because of the incredible spread of the network. One specific aspect of this social network site that widely discussed in the news and heavily researched in academic circles is the security and privacy issues of Facebook. Facebook provides different security mechanisms and one of these mechanism is a facility known as 3 trusted friends that Facebook provide to its users to recover their accounts in case that they forget their passwords which it could be a vulnerability as well if it is misused by malicious person. The purpose of this paper is to introduce this new 3 trusted friend's vulnerability that could be exploited by a hacker to recover the password of a legitimate user and hack his account.
Hsp60 Peptide Therapy of NOD Mouse Diabetes Induces a Th2 Cytokine Burst and Downregulates Autoimmunity to Various β-Cell Antigens (1997)

A peptide of the human 60-kDa heat-shock protein (hsp60), designated p277, was found to be useful as a therapeutic agent to arrest the autoimmune process responsible for diabetes in nonobese diabetic (NOD) mice. The effectiveness of peptide treatment was associated with the induction of peptide-specific antibodies of the IgG1 but not of the IgG2a isotype, suggesting the possibility that a Th2-type response may have been induced. We now report that the effectiveness of p277 treatment is associated with the transient activation of anti-p277 splenic T-cells that produce the Th2 cytokines interleukin-4 (IL-4) and IL-10. The Th2 response to p277 was associated with reduced Th1-type autoimmunity to hsp60 and to two other target antigens associated with diabetes: GAD and insulin. The Th2 shift appeared to be relatively specific; spontaneous T-cell reactivity to a bacterial antigen peptide remained in the Th1 mode in the p277-treated mice. Moreover, treatment with the bacterial peptide did not induce a change in cytokine profile, and it did not affect progression of the disease. Thus, effective peptide treatment of the diabetogenic process associated with the induction of antibodies may be explained by selective and transient activation of Th2 autoimmune reactivity.
Extraction of diffuse correlation spectroscopy flow index by integration of <i>N</i>th-order linear model with Monte Carlo simulation (2014)

Conventional semi-infinite solution for extracting blood flow index (BFI) from diffuse correlation spectroscopy (DCS) measurements may cause errors in estimation of BFI (<i>αD<sub>B</sub></i> ) in tissues with small volume and large curvature. We proposed an algorithm integrating <i>N</i>th-order linear model of autocorrelation function with the Monte Carlo simulation of photon migrations in tissue for the extraction of <i>αD<sub>B</sub></i> . The volume and geometry of the measured tissue were incorporated in the Monte Carlo simulation, which overcome the semi-infinite restrictions. The algorithm was tested using computer simulations on four tissue models with varied volumes/geometries and applied on an <i>in vivo</i> stroke model of mouse. Computer simulations shows that the high-order (<i>N</i> ≥ 5) linear algorithm was more accurate in extracting <i>αD<sub>B</sub></i> (errors < ±2%) from the noise-free DCS data than the semi-infinite solution (errors: -5.3% to -18.0%) for different tissue models. Although adding random noises to DCS data resulted in <i>αD<sub>B</sub></i> variations, the mean values of errors in extracting <i>αD<sub>B</sub></i> were similar to those reconstructed from the noise-free DCS data. In addition, the errors in extracting the relative changes of <i>αD<sub>B</sub></i> using both linear algorithm and semi-infinite solution were fairly small (errors < ±2.0%) and did not rely on the tissue volume/geometry. The experimental results from the <i>in vivo</i> stroke mice agreed with those in simulations, demonstrating the robustness of the linear algorithm. DCS with the high-order linear algorithm shows the potential for the inter-subject comparison and longitudinal monitoring of absolute BFI in a variety of tissues/organs with different volumes/geometries.
Characteristics of a dual-shape core fiber with an α-index center core (1987)

The bending-loss and dispersion-sensitivity characteristics of a dispersion-shifted dual-shape core fiber with an alpha index center core are described. Calculations show that these characteristics can be improved by decreasing a and that a bend-optimized, dual-shaped core fiber exhibits a small bending loss and a large mode field diameter.
Development of a System to Provide Full, Real-timeRemote Control of a Scanning Electron Microscopeacross the Second Generation Internet: The Teaching SEM (2000)

The development and makeup of a real-time full remote control system for the University of Michigan, Department of Materials Science and Engineering Teaching SEM is described. The instrument was initially controlled via the campus local area Ethernet network and cable TV network. The latest implementation employs Fast Ethernet, Asynchronous Transfer Mode (ATM) networks, and moving picture experts group (MPEG) video encoding to effect the remote control via the computer network alone. Remote control demonstrations from Washington, DC, Dearborn, MI, and Emerson School, Ann Arbor, MI are described.
Spectral analysis in cyclic changes of human sleep evaluation (1996)

In this study cyclic changes of human sleep structure were examined. For whole-night polysomnograms of 35 healthy volunteers of both sexes, manual hypnograms were created and divided into NREM-REM cycles. EEG signals from C3-A2 derivation were analysed by computer using a Fast Fourier Transform (FFT). For consecutive NREM-REM cycles of individual sleep stages, EEG power density contents for delta, theta, alpha, sigma and beta waves were analysed. For consecutive sleep cycles, a clear decrease in NREM sleep duration, especially slow wave sleep duration, was obtained. In addition, a decrease in power density of delta waves was observed. For consecutive sleep cycles, increases in REM sleep duration and in power density of theta and alpha waves were obtained. In consecutive sleep cycles, high amplitude delta slow waves are replaced by higher frequency and lower amplitude waves. Thus stages of NREM sleep are replaced by stages of REM.
A fresh look at migraine therapy (2001)

Successful management of migraine headaches involves identifying and avoiding headache triggers and using appropriate abortive therapy once a headache is recognized. Pain relief measures include over-the-counter analgesics, parenteral NSAID therapy when needed, and use of antiemetics and cold packs. Narcotic analgesics are best used only as a "last resort" measure. Prophylactic therapy should be considered for patients who have more than two acute migraine attacks each month or whose daily activities are seriously compromised by headaches. For the patient in whom status migrainosus threatens well-being, hospitalization and more intensive therapy may be needed.
DSiP distributed systems intercommunication protocol: a traffic engineering solution for secure multichannel communication (2011)

The importance of reliable telecommunication is constantly increasing. The DSiP-solution makes it possible to distribute all telecommunication among several operators and methods, resulting in a true multichannel communication system. The DSiP-multichannel routing solution increases reliability, security and integrity in telecommunication and allows regular communication methods to be used in mission critical telemetry systems. This is achieved by splitting risks between operators and communication channels; better routing capabilities; taking security and intrusion risks into account; and adding modularity.
Emulsion polymerization of vinyl stearate (1967)

Abstract The polymerization of vinyl stearate in aqueous emulsions with a non‐ionic emulsifying agent and potassium peroxydisulfate as initiator has been investigated by use of a dilatometric method to follow the reaction. In general, the reaction kinetics do not follow the pattern established for styrene. Variation of initiator concentration produced latices containing approximately equal numbers of latex particles, even though the rate of reaction was almost directly proportional to the peroxydisulfate concentration. For a given initiator and monomer concentration polymerization occurs very slowly when the monomer is completely solubilized but as the number of micelles is reduced and the number of emulsion droplets increased, the rate increases to an optimum value, whereafter it decreases. A mechanism is proposed by which the sparsely soluble vinyl stearate reacts and redistributes itself into latex particles of a different size range from the micelles and emulsion droplets originally present.
Intermittent two phase flow in horizontal pipes: Predictive models (1978)

Abstract A semi‐mechanistic model for two phase gas‐liquid slug flow proposed recently by Dukler and Hubbard has been modified and extended to apply to the entire intermittent flow regime. Flow predictions of the model proposed in this paper are compared with detailed experimental data recently obtained for an air‐oil system. The model requires the use of empirical correlations for the slug velocity and the in situ liquid volume fraction in the slug. In addition, either the slug frequencies or length corresponding to the given design conditions must be known. However, calculated values of average pressure gradient and in situ liquid volume fraction are relatively insensitive to these latter parameters, and in fact, good results are obtained assuming a constant slug length. The paper includes a discussion of the limitations of the proposed model and the expected direction of further study required to extend its mechanistic aspects.
A study of equipment sizes and constraints for a unified power flow controller (2002)

This paper provides a quantitative measurement of the benefit that a unified power flow controller (UPFC) can provide to increase firm power transfer between two large power systems. Included is a complete model for a UPFC control system that contains bus voltage control by the shunt inverter, real power transfer between the shunt and series inverters, and real and reactive power control for the transmission line into which the series inverter is inserted. A significant part of the model is representation of dynamic limits that coordinate injected current limits for the shunt inverter, power transfer limits between inverters, voltage injection limits for the series inverter, current limits for the series inverter, and line voltage limits for the transmission line. This paper contains a simple system simulation to demonstrate the coordinated dynamic control and illustrate issues that system planning engineers must consider in defining applications for a UPFC.
Monodispersed Fine Particles. (1992)

This article is concerned with the recent controlling techniques of mean size, structure and heterojunction of monodispersed fine particle as modern advanced materials. For the control of mean size, the general principle and a theoretical and experimental approach to quantitative control of the mean size are introduced. Also, the relationship between particle shape and the structure is discussed and a rather new idea of polymerize growth mechanism for the growth of metal oxides is referred to. Finally, one of the most sophisticated particles, heterojunctioned particles, is introduced and the mechanism of the formation of junctioned particles consisting of a silver chloride host and silver bromide guests is delineated as an example.
Regulatory and Pathogenic Roles of Müller Glial Cells in Retinal Neovascular Processes and Their Potential for Retinal Regeneration (2009)

Müller glial cells are known to play a very important role in retinal homeostasis, and many metabolic functions have been ascribed to these cells not only in the normal but in the diseased retina. This chapter addresses a wide variety of activities attributed to Müller glial cells. It describes how activation of Müller glia by pro-inflammatory and pro-angiogenic factors may contribute to the development of neovascularisation and fibrosis, the characteristic pathological features of diabetic retinopathy. The chapter also highlights the regulatory role that Müller glia exert in various retinal functions, including the prevention of neural damage due to their production of neurotrophins in response to inflammatory and angiogenic signals. Recent findings that a sub-population of Müller glia have the ability to regenerate retinal neurons in adult life are described, and the implications for the potential use of Müller stem cells for cell-based therapies to regenerate diabetic retina are discussed.
