Protocols for a wireless-ATM multihop network (2002)

A medium access control protocol for a wireless multihop network is described and evaluated. The network is able to guarantee the bandwidth contracted to a connection in a hidden station environment and to most efficiently use the spectrum capacity by providing a mechanism for dynamic channel allocation to services. Both channel and packet switched services are supported, based on real channel connections. Ad-hoc networks without a central control node can be realized due to the ability of any station to route connections according to the current meshing of the network. Channels are established and used for the duration of a so called train of data packets, released when the train ends and reestablished when the next train arrives. To guarantee available capacity of the network for the reestablishment of a connection, connection admission control is applied and new connections are accepted only if spare capacity is available. The traffic performance of the proposed protocol is given by means of a simulation study in an example scenario.
Catalytic, Highly Enantio, and Diastereoselective Nitroso Diels−Alder Reaction (2004)

This communication presents studies that nitroso Diels-Alder adduct has been furnished in uniformly high yield and high enantioselectivity using nitrosopyridine as a substrate and copper as a catalyst. The obtained Diels-Alder adduct was easily transformed to corresponding chiral amino alcohols without loss of enantioselectivity.
Functional Electrical Stimulation: A MatLab Based Tool for Designing Stimulation Patterns (2006)

We developed user-friendly software that generates stimulation profiles by using user-customized model-based control of walking. The model is a multi-segment structure with pin and ball joints. A pair of an agonist and an antagonistic muscles acts at each joint. Each muscle is modeled by a three-compartment multiplicative model. The control is based on optimization that uses a cost function that minimizes the tracking error of the joint angles and levels of muscles activations. The inputs to the simulation are trajectories and user characteristic model parameters. The outputs of the simulation are levels of muscle activations vs. time. The software allows for interactive testing of various walking trajectories and model parameters since the simulation is integrated into a database of individuals and reference trajectories. The simulation was realized in the MatLab environment with multiple windows graphical user interface. Here we present an example: stimulation patterns for the shank-foot system that is applicable for walking control in hemiplegic individuals.
Towards Scalable Cluster Auditing through Grammatical Inference over Provenance Graphs (2018)

Investigating the nature of system intrusions in large distributed systems remains a notoriously difficult challenge. While monitoring tools (e.g., Firewalls, IDS) provide preliminary alerts through easy-to-use administrative interfaces, attack reconstruction still requires that administrators sift through gigabytes of system audit logs stored locally on hundreds of machines. At present, two fundamental obstacles prevent synergy between system-layer auditing and modern cluster monitoring tools: 1) the sheer volume of audit data generated in a data center is prohibitively costly to transmit to a central node, and 2) systemlayer auditing poses a "needle-in-a-haystack" problem, such that hundreds of employee hours may be required to diagnose a single intrusion.
Molecular Population Genetics of Drosophila Immune System Genes (1997)

A striking aspect of many vertebrate immune system is the exceptionally high level of polymorphism they harbor. A convincing case can be made that this polymorphism is driven by the diversity of pathogens that face selective pressures to evade attack by the host immune system. Different organisms accomplish a defense against diverse pathogens through mechanisms that differ widely in their requirements for specific recognition. It has recently been shown that innate defense mechanisms, which use proteins with broad-spectrum bactericidal properties, are common to both primitive and advanced organisms. In this study we characterize DNA sequence variation in six pathogen defense genes of Drosophila melanogaster and D. mauritiana, including Andropin; cecropin genes CecA1, CecA2, CecB, and CecC; and Diptericin. The necessity for protection against diverse pathogens, which themselves may evolve resistance to insect defenses, motivates a population-level analysis. Estimates of variation levels show that the genes are not exceptionally polymorphic, but Andropin and Diptericin have patterns of variation that differ significantly from neutrality. Patterns of interpopulation and interspecific differentiation also reveal differences among the genes in evolutionary forces.
A Recurrent Neural-Network-Based Real-Time Dynamic Model for Soft Continuum Manipulators (2021)

This paper introduces and validates a real-time dynamic predictive model based on a neural network approach for soft continuum manipulators. The presented model provides a real-time prediction framework using neural-network-based strategies and continuum mechanics principles. A time-space integration scheme is employed to discretize the continuous dynamics and decouple the dynamic equations for translation and rotation for each node of a soft continuum manipulator. Then the resulting architecture is used to develop distributed prediction algorithms using recurrent neural networks. The proposed RNN-based parallel predictive scheme does not rely on computationally intensive algorithms; therefore, it is useful in real-time applications. Furthermore, simulations are shown to illustrate the approach performance on soft continuum elastica, and the approach is also validated through an experiment on a magnetically-actuated soft continuum manipulator. The results demonstrate that the presented model can outperform classical modeling approaches such as the Cosserat rod model while also shows possibilities for being used in practice.
Increasing the Efficiency of the Electroflotation Recovery of Finely Dispersed Carbon Material in the Presence of Surfactants from Liquid Technogenic Waste (2018)

The electroflotation recovery of a finely dispersed carbon material, namely, carbon nanoflakes, from aqueous solutions in the pH range of 3.0–11.0 in the presence of different forms of surfactants has been experimentally studied. The electroflotation of carbon nanoflakes from aqueous solutions with the addition of the FeCl3 coagulant has been investigated. The experimental dependences of the degree of recovery and the electrokinetic potential on the pH value of the medium in the presence and absence of a coagulating agent have been derived. The optimal values of characteristics such as the pH value of the medium, volumetric current density, electroflotation time, and the initial concentrations of Fe3+ ions and surfactants for effective electroflotation of carbon nanoflakes have been found.
The Vega X-Band Enhancer-An Advanced Technological Aid to Navigation (1971)

A practical x-band enhances which will respond to marine radars operating in the 9300 to 9500 MHz frequency band without the necessity for radar tuning has been developed by Vega Precision Laboratories and field tested. The reply echo from the all solid state enhancer will be seen as a normal radar echo except that it is fixed high power and coded for identification. If the radar receiver is detuned then the enhancer reply overrides the usual radar clutter such as unwanted echoes from the sea, land or rain. The equipment may be strategically located and used for navigation of rivers and waterways or it may be used to enhance the radar return from small boats for collision avoidance and also search and rescue.
CP7_E2alf oral vaccination confers partial protection against early classical swine fever virus challenge and interferes with pathogeny-related cytokine responses (2013)

The conventional C-strain vaccine induces early protection against classical swine fever (CSF), but infected animals cannot be distinguished from vaccinated animals. The CP7_E2alf marker vaccine, a pestivirus chimera, could be a suitable substitute for C-strain vaccine to control CSF outbreaks. In this study, single oral applications of CP7_E2alf and C-strain vaccines were compared for their efficacy to induce protection against a CSF virus (CSFV) challenge with the moderately virulent Bas-Rhin isolate, in pigs as early as two days post-immunization. This work emphasizes the powerful potential of CP7_E2alf vaccine administered orally by a rapid onset of partial protection similar to that induced by the C-strain vaccine. Furthermore, our results revealed that both vaccinations attenuated the effects induced by CSFV on production of the pig major acute phase protein (PigMAP), IFN-α, IL-12, IL-10, and TGF-β1 cytokines. By this interference, several cytokines that may play a role in the pathogeny induced by moderately virulent CSFV strains were revealed. New hypotheses concerning the role of each of these cytokines in CSFV pathogeny are discussed. Our results also show that oral vaccination with either vaccine (CP7_E2alf or C-strain) enhanced CSFV-specific IgG2 production, compared to infection alone. Interestingly, despite the similar antibody profiles displayed by both vaccines post-challenge, the production of CSFV-specific IgG1 and neutralizing antibodies without challenge was lower with CP7_E2alf vaccination than with C-strain vaccination, suggesting a slight difference in the balance of adaptive immune responses between these vaccines.
Electronic simulation of Josephson tunneling, including the effects of frequency, temperature, and the superconducting energy gap (1982)

An electronic device which simulates the Werthamer theory of Josephson tunneling is described. The simulator includes the effects of frequency, temperature, and the superconducting energy gap. The nonlinear quasi-particle resistance, and the related reactive term, are also modeled. Current-voltage characteristics obtained with the simulator are presented for a variety of temperatures under both current and voltage bias conditions. Phenomena such as subgap structure, the Riedel peak, and photon-assisted tunneling are also illustrated. Finally, brief evidence of a new form of oscillatory behavior associated with the Riedel peak is presented.
Introduction of the Revolving Vane Expander (2009)

Expanders are becoming increasingly important as refrigeration systems that use carbon dioxide gain popularity. This paper discusses the revolving vane expander, which is a highly efficient, new type of rotary expander. Although the design is similar to that of a rolling piston machine, its design eliminates the friction power losses at all rubbing surfaces, except for at the vane side and the shaft bearings. In this paper, the expander design and its working principles are introduced. A mathematical model is also presented that has been used to investigate the operating characteristics of the expander. The theoretical results confirm that the only significant frictional losses left are at the shaft bearing and that a mechanical efficiency of 94.2% can be obtained.
A scheduler for mobile cloud based on weighted metrics and dynamic context evaluation (2015)

Resource scarcity is a major obstacle for many mobile applications, since devices have limited energy power and processing potential. As an example, there are applications that seamlessly augment human cognition and typically require resources that far outstrip mobile hardware's capabilities, such as language translation, speech recognition, and face recognition. The use of cloud computing may tackle this problem. This study presents SmartRank, a scheduling framework to perform load partitioning and offloading for mobile applications using cloud computing to increase performance in terms of response time. We first explore a benchmarking of face recognition application using mobile cloud and confirms its suitability to be used as case study with SmartRank. We have applied the approach to a face recognition process based on two strategies: cloudlet federation and resource ranking through balanced metrics (level of CPU utilization and round-trip time). Second, using a full factorial experimental design we tuned the SmartRank with the most suitable partitioning decision calibrating scheduling parameters. Nevertheless, SmartRank uses an equation that is extensible to include new parameters and make it applicable to other scenarios.
Anatomy of the trading process empirical evidence on the behavior of institutional traders (1995)

This paper examines the behavior of institutional traders. We use unique data on the equity transactions of 21 institutions of differing investment styles which provide a detailed account of the anatomy of the trading process. The data include information on the number of days needed to fill an order and types of order placement strategies employed. We analyze the motivations for trade, the determinants of trade duration, and the choice of order type. The analysis provides some support for the predictions made by theoretical models, but suggests that these models fail to capture important dimensions of trading behavior.
Development of types of psyllium-enriched bread as part of a cholesterol lowering diet. (2000)

Psyllium seed husks derived from Plantago ovata are a concentrated source of dietary fiber and contain ∼ 85% total dietary fiber and ∼ 71% soluble fiber, respectively. In the USA psyllium is well recognized for its cholesterol-lowering effect and has already been added to some food products such as ready-to-eat breakfast cereals. Moreover, the Food and drug Administration FDA has ruled that certain foods containing soluble fiber from psyllium can make a health claim in respect to reducing the risk of coronary heart disease. In Germany the cholesterol-lowering potential of psyllium is not yet appreciated. The objective of the present study was to develop different types of psyllium supplemented breads, e.g. wheat bread, rye bread and mixed grain breads, was aimed that 3-4 slices of bread should contain 10-15 g and therefore 15% of the flour was substituted with psyllium. Human studies have demonstrated that the daily consumption of 10-15 g psyllium will produce a significant hypocholesterolemic effect. The high viscosity of psyllium affected the dough preparation and baking process, therefore customary recipes needed to be modified. Especially the amount of water added to the dough needed to be increased. Due to the increased amount of water that was added to the dough the freshness of the breads was increased but the tendency to bread mould was shortened. After modifying the recipes and the baking process it was possible to bake a psyllium-supplemented wheat bread as well as two types of mixed wheat and rye breads which did not differ from the characteristic of regular breads. Baking tests to make a whole meal rye bread however were not satisfactory because of a number of problems that occurred during the baking process. In a sensory test the psyllium-breads were evaluated as good tasting and as palatable as the conventional control breads. However, there was a particular sandy taste of the psyllium-breads. In conclusion, after modifying the recipes it was possible to bake palatable psyllium-enriched breads with a comparable quality of regular breads. Since bread is a staple food in people's diet, the daily consumption of 3-4 slices containing 10-15 g psyllium could easily be incorporated into a cholesterol-lowering dietary therapy or could help to prevent hyperlipidemia.
Evaluating the Role of Time in Investigative Analysis of Document Collections (2012)

Time is a universal and essential aspect of data in any investigative analysis. It helps analysts establish causality, build storylines from evidence, and reject infeasible hypotheses. For this reason, many investigative analysis tools provide visual representations designed for making sense of temporal data. However, the field of visual analytics still needs more evidence explaining how temporal visualization actually aids the analysis process, as well as design recommendations for how to build these visualizations. To fill this gap, we conducted an insight-based qualitative study to investigate the influence of temporal visualization on investigative analysis. We found that visualizing temporal information helped participants externalize chains of events. Another contribution of our work is the lightweight evaluation approach used to collect, visualize, and analyze insight.

Determinants of severe QTc prolongation in a real-world gerontopsychiatric setting (2023)

Introduction QT c prolongation carries the risk of ventricular tachyarrhythmia (Torsades de Pointes) and sudden cardiac death. Psychotropic drugs can affect ventricular repolarization and thus prolong the QT c interval. The present study sought to investigate the risk factors (pharmacological and non-pharmacological) of severe QT c prolongation in gerontopsychiatric patients. Methods Electrocardiograms of patients on a gerontopsychiatric ward were screened for QT c prolongation. Medication lists were examined utilizing the AzCERT classification. Potential drug interactions were identified with the electronic drug interaction program mediQ. Results The overall prevalence of QT c prolongation was 13.6%, with 1.9% displaying severe QT c prolongation (≥ 500 ms). No statistically significant differences between patients with moderate and severe QT c prolongation were identified; however, patients with severe QT c prolongation tended to take more drugs ( p = 0.063). 92.7% of patients with QT c prolongation took at least one AzCERT-listed drug, most frequently risperidone and pantoprazole. Risperidone and pantoprazole, along with pipamperone, were also most frequently involved in potential drug interactions. All patients displayed additional risk factors for QT c prolongation, particularly cardiac diseases. Conclusion In addition to the use of potentially QT c -prolonging drugs, other risk factors, especially cardiac diseases, appear to be relevant for the development of QT c prolongation in gerontopsychiatric patients. Pantoprazole was frequently involved in potential drug interactions and should generally not be used for more than 8 weeks in geriatric populations. As clinical consequences of QT c prolongation were rare, potentially QT c -prolonging drugs should not be used overcautiously; their therapeutic benefit should be considered as well. It is paramount to perform diligent benefit–risk analyses prior to the initiation of potentially QT c -prolonging drugs and to closely monitor their clinical (side) effects.
Integrated voice/data packet switching techniques for future military networks (1980)

Virtual circuit and pure packet (datagram) based switching techniques are studied for future application to the integrated voice/data telecommunications. The coexistence of voice with both interactive and bulk data in an integrated network suggests the desirability of a mixed switching technique to allow the efficient sharing of both the switching and communications resources. Such a mixed packet switching scheme is also evaluated. It uses virtual circuit for regular traffic (voice and bulk data), and uses pure packet (datagram) for bursty traffic (interactive and query/response). It also adapts to changes in voice/ data input traffic mixture.

Simulation of Adaptive Array Algorithms for CDMA Systems (1996)

The increasing demand for mobile communication services without a corresponding increase\nin RF spectrum allocation motivates the need for new techniques to improve spectrum\nutilization. The CDMA and adaptive antenna array are two approaches that shows real\npromise for increasing spectrum efficiency. In this research, we investigate the performance\nof different blind adaptive array algorithms in the CDMA systems. Two novel algorithms,\nleast-squares despread respread multitarget array (LS-DRMTA) and least-squares despread\nrespread multitarget constant modulus algorithm (LS-DRMTCMA), are developed, and a\nMATLAB â ¢ simulation testbed is created to compare the performance of these two novel\nalgorithms with those of the multitarget least-squares constant modulus algorithm (MTLSCMA)\nand multitarget steepest-descent decision-directed (MT-SDDD) algorithm. It is\nshown from the simulation results that these two novel algorithms can outperform the\nother algorithms in all the test situations (e. g., AWGN channel, timing offset case, frequency\noffset case, and multi path environment). It is also shown that these two algorithms\nhave less complexity and can converge faster than the other algorithms.
The Great Wall of Technology Still Stands (1994)

Ever since my first job in the computer industry, as a systems engineer at Strategic Air Command Headquarters near Omaha, Nebraska, I've sensed a separation between people who worked with computers and the rest of an organization. At SAC, the computer systems and operations divisions were housed three stories underground for security purposes. The four-star general in charge was housed on the top floor-- above ground. That separation was more than physical. I don't think the good general really understood what we were doing, but he knew he couldn't manage SAC without us. Now, 36 years later, I still sense a separation between the providers of technology (whether in-house organizations or outsource companies) and those who rely on technology. Surveys conducted by research firms and consultants as recently as this year tell us that a primary goal of the chief information officer is to Information Systems and corporate goals. According to CSC/Index of Cambridge, Mass., this issue ranked first or second in six of the seven annual surveys conducted. Other surveys conducted with chief executive officers show that over half of them are still dissatisfied with their company's information systems capabilities. If we believe what these surveys are telling us, it's safe to conclude that the convergence of goals represented by the CIO and CEO has yet to take place. I believe technology is an essential component of any bank's ability to conduct business. But technology has to serve a master. Too many times, the CIO thinks technology is the end result. Too many times the information systems people get so tied up in how they are going to deliver systems solutions that they don't consider why they are building or acquiring the capabilities. In almost every case banks want the maximum performance from a system, and they usually want to automate everything. That's a good way to start, but as a consultant I am obliged to align the system with the strategic plan and the purse of the bank. To do that I engage management in a soul-searching exercise. Following are the questions we try to answer in preparation for technology investments. Can the technology... ...Gain new customers for the bank? A lot of truth is told in informal meetings, when outside directors ask their management team this question. Sometimes a strong case can be made, other times the bank manager confesses that the capability is just nice to have. ...Reduce the number of employees? I don't accept a reduction of 3. …
