Design and implementation of a single system image operating system for ad hoc networks (2005)

In this paper, we describe the design and implementation of a distributed operating system for ad hoc networks. Our system simplifies the programming of ad hoc networks and extends total system lifetime by making the entire network appear as a single virtual machine. It automatically and transparently partitions applications into components and dynamically finds them a placement on nodes within the network to reduce energy consumption and to increase system longevity. This paper describes our programming model, outlines the design and implementation of our system and examines the energy efficiency of our approach through extensive simulations as well as validation of a deployment on a physical testbed. We evaluate practical, power-aware, general-purpose algorithms for component placement and migration, and demonstrate that they can significantly increase system longevity by effectively distributing energy consumption and avoiding hotspots.
Automotive Software Engineering Principles, Processes, Methods, and Tools (2005)

The deployment of onboard electronic systems and software in the motor vehicle has increased steadily since the early 1970s. The software-based implementation of vehicle functions must take into consideration higher demands on safety and reliability in relation to lower cost ceilings, longer product life cycles and shorter development times. The driver-vehicle-environment system, essential system basics, development processes for electronic systems / software, and the methods and tools used in the development, manufacture, and service of electronic systems are described in this book, which was translated from German into English by Roger Carey.
Computational models satisfying relative angle constraints for 2-dimensional segmented bodies (2006)

Abstract Planar hinged segmented bodies have been used to represent models of biomechanical systems. One characteristic of a segmented body moving under gravitational acceleration and torques between segments is the possibility that the body's segments spin through more than a revolution or past a natural limit, and a computational mechanism to stop such behaviour should be provided. This could be done by introducing angle constraints between segments, and computational models utilising optimal control are studied here. Three models to maintain angle constraints between segments are proposed and compared. These models are: all-time angle constraints, a restoring torque in the state equations and an exponential penalty model. The models are applied to a 2-D three-segment body to test the behaviour of each model when optimising torques to minimise an objective. The optimisation is run to find torques so that the end effector of the body follows the trajectory of a half-circle. The result shows the behaviour of each model in maintaining the angle constraints. The all-time constraints case exhibits a behaviour of not allowing torques (at a solution) which makes segments move past the constraints, while the other two show a flexibility in handling the angle constraints which is more similar to what occurs in a real biomechanical system.
Comprehensive analysis of the expression of the metastasis-associated gene 1 in human neoplastic tissue. (2006)

This study characterizes MTA1 expression for the first time across a broad spectrum of primary tumors, demonstrating expression in both benign and malignant neoplasms in addition to showing an association with neuroendocrine differentiation. We also found evidence that MTA1 expression is associated with tissue invasion but may not be sufficient for the progression to metastatic stages.
Edge and modular significance assessment in individual-specific networks (2023)

Individual-specific networks, defined as networks of nodes and connecting edges that are specific to an individual, are promising tools for precision medicine. When such networks are biological, interpretation of functional modules at an individual level becomes possible. An under-investigated problem is relevance or "significance" assessment of each individual-specific network. This paper proposes novel edge and module significance assessment procedures for weighted and unweighted individual-specific networks. Specifically, we propose a modular Cook's distance using a method that involves iterative modeling of one edge versus all the others within a module. Two procedures assessing changes between using all individuals and using all individuals but leaving one individual out (LOO) are proposed as well (LOO-ISN, MultiLOO-ISN), relying on empirically derived edges. We compare our proposals to competitors, including adaptions of OPTICS, kNN, and Spoutlier methods, by an extensive simulation study, templated on real-life scenarios for gene co-expression and microbial interaction networks. Results show the advantages of performing modular versus edge-wise significance assessments for individual-specific networks. Furthermore, modular Cook's distance is among the top performers across all considered simulation settings. Finally, the identification of outlying individuals regarding their individual-specific networks, is meaningful for precision medicine purposes, as confirmed by network analysis of microbiome abundance profiles.
Solid State Synthesis and Characterization of Carbo-Nitride Materials (2000)

The preparation of stoichiometric sp(sup 2)-bonded amorphous carbon nitride a-C3N4 in gram quantities was successfully achieved by performing a solid-state reaction of cyanuric halides C3N3X3 (X=Cl, F) with lithium nitride L3N at temperatures 300-380 deg C. Addition of boron precursors, e. g., NaBF4, resulted in preparation of a nitrogen-rich BC-N powder of approximately B3C3N7 composition and showing thermal stability up to temperatures of 1000 deg C. The densification of micronized powders by cold isothermal pressing has produced disk-shaped ceramics of C3N4 and B-C-N materials, being lighter than graphite and boron nitride h-BN, respectively. Further modification of the reaction by introduction of porous substrates and templates has led to preparation of a previously unknown material - sphere-shaped nanoscale-size carbon nitride built by stacking of curved C3N4 layers. Preliminary high pressure/high temperature experiments with the C3N4 powder as precursor have demonstrated that the structure of carbon nitride changes under pressures of 8 to 12 Gpa from amorphous to a more ordered graphite-like one, retaining the C3N4 stoichiometry at temperatures up to 500 deg C and losing nitrogen at higher temperatures. The overall amorphous morphology of the carbon nitride has so far precluded the generation of a secondary electron emission by this material during the tests performed. Continuing attempts to prepare crystalline carbo-nitride phases both by the high pressure treatment of amorphous powder precursors and by an appropriate synthetic routes designed are in progress in our laboratory.
A comparative analysis of undersampling techniques for network intrusion detection systems design (2021)

Intrusion Detection Systems (IDS) figure as one of the leading solutions adopted in the network security area to prevent intrusions and ensure data and services security. However, this issue requires IDS to be assertive and efficient processing time. Undersampling techniques allow classifiers to be evaluated from smaller subsets in a representative manner, aiming high assertive metrics in less processing time. There are several solutions in literature for IDS projects, but some criteria are not respected, such as the adoption of a replicable methodology. In this work, we selected three undersampling methodologies: random, Cluster centroids, and NearMiss in two novel unbalanced datasets (CIC2017 and CIC2018) for comparison between five classifiers using cross-validation and Wilcoxon statistical test. Our main contribution is a systematic and replicable methodology for using subsampling techniques to balance the data sets adopted in the IDS project. We choose three metrics for classifier's choice in an IDS design: accuracy, f1-measure, and processing time. The results indicate that the under-sampling by Cluster centroids presents the best performance when applied to distance-based classifiers. Moreover, under-sampling techniques influence the process of choosing the best classifier in the design of an IDS.
Genomic analyses of two novel biofilm-degrading methicillin-resistant Staphylococcus aureus phages (2019)

The present work addressed the possibility of using phages as potential biocontrol agents for biofilm-producing MRSA.
A Compact, Supply-Voltage Scalable 45–66 GHz Baseband-Combining CMOS Phased-Array Receiver (2014)

This paper presents a four-element phased-array receiver which achieves 38% fractional bandwidth around 55 GHz. Baseband phase-shifting is employed to eliminate wideband phase-shifters, power dividers, and quadrature splitters operating at millimeter-wave frequencies. Antenna weighting and combining are accomplished using a highly digital Cartesian phase-shifter and current summation, respectively. Transformer-coupling techniques are introduced in the LNA to simultaneously achieve wide bandwidth, reduced noise figure, gain boosting and neutralization. Cascode-free and folded topologies are used throughout to enable operation from a scalable supply voltage. To overcome challenges associated with wideband LO distribution, the LO network employs multiconductor transmission lines to distribute four-phase LO signals. The LO distribution network is absorbed into the LO buffers and terminated by distributed LC loads near the I/Q mixers in each phased-array element. The phased-array receiver is fabricated in a 45 nm SOI CMOS process and achieves 26.2 dB (20.2 dB) of element gain over 21 GHz (19 GHz) of 3 dB bandwidth with 5.5 dB/9.8 dB (7.7 dB/12 dB) minimum/maximum NF while dissipating 30 mW/element (14 mW/element) from a 1.1 V (0.6 V) supply voltage. The worst case -1 dB (input) compression is -28 dBm at 1.1 V. A worst case coupling of 26 dB (45 dB) is measured between adjacent (nonadjacent) elements. The IF bandwidth is 1.2 GHz, limited by the wirebond and PCB interface to the chip. The design occupies only 0.225 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> per element including LO buffer/distribution.
Crosstalk Fault Detection for Interconnection Lines Based on Path Delay Inertia Principle (2005)

The crosstalk fault becomes more and more important in the deep submicron SoC and its detection involves sophisticated timing measurement. In this paper, a new test scheme to detect the crosstalk fault, based on the path delay inertia, for interconnection lines in SoC is proposed. The scheme, without using timing measurement, applies a transition on the aggressor line and a critical width pulse, CWP, to the victim line and detects the propagation of the CWP at the output of the victim line. The scheme is simple and simulation analysis and experiments show that it is effective in detecting crosstalk faults.
A comparison of differential and coherent reception for a coded OFDM system in a low C/I environment (2002)

This paper compares the performance of differential and coherent QPSK for a high data rate slow frequency hopping (SFH) OFDM system in a channel with strong co-channel interference. Two-branch diversity reception and channel coding are included in the comparison. The coherent system uses a rate 1/2, 64-state convolutional code and includes a relatively high amount of pilot symbol overhead to facilitate the measurement of channel state information (CSI) including the instantaneous co-channel interference level. The CSI is incorporated in the combining and decoding process to improve the decoded bit error rate performance. Although the differential system does not support the measurement of the co-channel interference level, the savings in pilot symbol overhead enables the use of a more powerful rate 1/3, 64-state convolutional code. By using a rate 1/2 code in the CSI-coherent system and a rate 1/3 code in the differential system, the information data rates of the two systems are similar. Results indicate that CSI-coherent system performs better than the differential system due to the inclusion of accurate CSI in the combining and decoding process.
A note on the use of inbreeding in progeny test schemes (1993)

In this note some theoretical and simulated results are presented comparing the selection response in a progeny test scheme that utilizes inbred offspring for testing, with respect to a standard progeny test. The theory indicates a substantial increase in selection response, although the advantage decreases as the number of dams mated to a sire and the number of offspring per dam increases. The advantage is at a maximum when the variation of the trait is due to segregation of recessive alleles at low frequencies unfavourable to the direction of selection. Computer simulation confirmed the advantage of the method. ZUSAMMENFASSUNG: Verwendung von Inzuchttieren bei der Nachkommenschaftsprüfung Hier wurden theoretische und simulierte Selektionserfolge konventioneller Nachkommenschaftsprüfung mit Prüfung von Inzuchtnachkommen verglichen. Theoretisch zeigt sich ein erheblicher Vorteil der letzteren, wenn dieser auch mit steigende Zahl von Partnern und deren Nachkommen abnimmt und nach null tendiert. Der Vorteil der Nachkommenschaftsprüfung ingezüchteter Nachkommen ist am höchsten, wenn seltene ungünstige rezessive Gene eine Rolle spielen. Rechner-Simulation bestätigt den Vorteil dieser Vorgangsweise.
Prototyping closed loop physiologic control with the medical device coordination framework (2010)

Medical devices historically have been monolithic units --- developed, validated, and approved by regulatory authorities as standalone entities. Despite the fact that modern medical devices increasingly incorporate connectivity mechanisms that enable device data to be streamed to electronic health records and displays that aggregate data from multiple devices, connectivity is not being leveraged to allow an integrated collection of devices to work together as a single system to automate clinical work flows. This is due, in part, to current regulatory policies which prohibit such interactions due to safety concerns.
The Effect of Visual and Auditory Information on the Perception of Pleasantness and Roughness of Virtual Surfaces (2017)

Despite the large number of studies on the multisensory aspects of tactile perception, very little is known regarding the effects of visual and auditory sensory modalities on the tactile hedonic evaluation of textures, especially when the presentation of the stimuli is mediated by a haptic device. In this study, different haptic virtual surfaces were rendered by varying the static and dynamic frictional coefficients of a Geomagic® Touch device. In Experiment 1, the haptic surfaces were paired with pictures representing everyday materials (glass, plastic, rubber and steel); in Experiment 2, the haptic surfaces were paired with sounds resulting from the haptic exploration of paper or sandpaper. In both the experiments, participants were required to rate the pleasantness and the roughness of the virtual surfaces explored. Exploration times were also recorded. Both pleasantness and roughness judgments, as well as the durations of exploration, varied as a function of the combinations of the visuo-tactile and the audio-tactile stimuli presented. Taken together, these results suggest that vision and audition modulate haptic perception and hedonic preferences when tactile sensations are provided through a haptic device. Importantly, these results offer interesting suggestions for designing more pleasant, and even more realistic, multisensory virtual surfaces.
Evolutionary cooperative spectrum sensing game: how to collaborate? (2010)

Cooperative spectrum sensing has been shown to be able to greatly improve the sensing performance in cognitive radio networks. However, if cognitive users belong to different service providers, they tend to contribute less in sensing in order to increase their own throughput. In this paper, we propose an evolutionary game framework to answer the question of "how to collaborate" in multiuser de-centralized cooperative spectrum sensing, because evolutionary game theory provides an excellent means to address the strategic uncertainty that a user/player may face by exploring different actions, adaptively learning during the strategic interactions, and approaching the best response strategy under changing conditions and environments using replicator dynamics. We derive the behavior dynamics and the evolutionarily stable strategy (ESS) of the secondary users. We then prove that the dynamics converge to the ESS, which renders the possibility of a de-centralized implementation of the proposed sensing game. According to the dynamics, we further develop a distributed learning algorithm so that the secondary users approach the ESS solely based on their own payoff observations. Simulation results show that the average throughput achieved in the proposed cooperative sensing game is higher than the case where secondary users sense the primary user individually without cooperation. The proposed game is demonstrated to converge to the ESS, and achieve a higher system throughput than the fully cooperative scenario, where all users contribute to sensing in every time slot.
Biochar alters the soil microbiome and soil function: results of next‐generation amplicon sequencing across Europe (2016)

Abstract Wide‐scale application of biochar to soil has been suggested as a mechanism to offset increases in CO 2 emissions through the long‐term sequestration of a carbon rich and inert substance to the soil, but the implications of this for soil diversity and function remain to be determined. Biochar is capable of inducing changes in soil bacterial communities, but the exact impacts of its application are poorly understood. Using three European sites [ UK SRC , short rotation coppice, French grassland ( FR ) and Italian SRF , short rotation forestry ( IT )] treated with identical biochar applications, we undertook 16S and ITS amplicon DNA sequencing. In addition, we carried out assessments of community change over time and N and P mobilization in the UK . Significant changes in bacterial and community structure occurred due to treatment, although the nature of the changes varied by site. STAMP differential abundance analysis showed enrichment of Gemmatimonadete and Acidobacteria in UK biochar plots 1 year after application, whilst control plots exhibited enriched Gemmataceae, Isosphaeraceae and Koribacteraceae . Increased mobility of ammonium and phosphates was also detected after 1 year, coupled with a shift from acid to alkaline phosphomonoesterase activity, which may suggest an ecological and functional shift towards a more copiotrophic ecology. Italy also exhibited enrichments, in both the Proteobacteria (driven by an increase in the order Rhizobiales ) and the Gemmatimonadetes . No significant change in the abundance of individual taxa was noted in FR , although a small significant change in unweighted UNIFRAC occurred, indicating variation in the identities of taxa present due to treatment. Fungal β diversity was affected by treatment in IT and FR , but was unaffected in UK samples. The effects of time and site were greater than that of biochar application in UK samples. Overall, this report gives a tantalizing view of the soil microbiome at several sites across Europe and suggests that although application of biochar has significant effects on microbial communities, these may be small compared with the highly variable soil microbiome that is found in different soils and changes with time.
Direct Synthesis of Electrowettable Carbon Nanowall–Diamond Hybrid Materials from Sacrificial Ceramic Templates Using HFCVD (2017)

Carbon‐on‐carbon materials carry the potential to be a major disruptive technology in fields like energy storage and electronics. In the present work, hot filament chemical vapor deposition (HFCVD) is used to synthesize carbon nanowall (CNW) tetrapods coupled to nanocrystalline diamond in a 3D hybrid network form. The CNW/diamond phase proportion as well as the structural morphology can be easily adjusted by the CVD parameters, allowing a single‐step synthesis of CNW micro‐ and nanopillars or CNW/diamond 3D hybrid materials, in the powder form or as interconnected free‐standing specimens. Additionally, the direct incorporation of SnO 2 catalyst particles during the one‐step CVD process is demonstrated. µ‐Raman and electron microscopy are used to understand the evolution of the morphological characteristics associated to the growth mechanism. The electrowettability behavior of the novel CNW/diamond hybrid material is demonstrated by electrochemical polarization studies. Such multifunctional carbon‐based hybrid 3D nanomaterials can find promising applications in advanced technologies such as energy storage.
Proxy Re-Encryption Schemes with Proxy Having Its Own Public/Private Keys (2010)

Proxy re-encryption (PRE) allows a ciphertext computed under Alice's public key to be transformed to those which can be decrypted by Bob. Since Blaze et al. introduced the concept of proxy re-encryption in Eurocrypt'98, there are many results on proxy re-encryption. However, all the proxy re-encryption schemes proposed until now assume the proxy having no its own public/private keys. In this paper, we investigate the benefits of proxy having its own public/private keys. We find that if we allow the proxy having its own public/private key, then the proxy can not act as malicious as the proxy in the traditional PRE. The proxy can be trusted to sign on the re-encrypted ciphertext, which somewhat make the authentication on the re-encrypted ciphertext no necessary again. Based on this observation, we give two proposals to try to solve two open problems in the PRE field.
Capillary flow between parallel plates in the presence of an electromagnetic field (2001)

This paper addresses the influence of electromagnetic field on the surface tension driven capillary flow between two parallel plates, with special reference to microchannel flows. Analytical solutions are obtained for different values of the non-dimensional parameters that represent the physics of the problem. It is observed that, in the presence of magnetic field, the application of electric current enhances the fluid flow rate and hence results in reduced time to fill the channel length when compared with the case without the electromagnetic field.
