Lightweight format-compliant encryption algorithm for JPEG 2000 images (2017)

The increasing usage of personal multimedia devices such as mobiles phones, smart glasses, etc. has pointed out the need for securing the captured/exchanged images content. Nevertheless, because of the limited resources of these novel platforms on one hand and the voluminous nature of multimedia content on the other hand, preserving multimedia content security remains a research challenge. In this paper, we tackle this issue by presenting a fast format-compliant selective encryption algorithm for JPEG 2000 images. It is based on selectively choosing data from the JPEG 2000 code-stream in a uniformly dynamic-key dependent manner to apply the proposed encryption algorithm. The encryption algorithm consists of two rounds of substitution-diffusion processes, based on a dynamic key, that is changed for every input image. Extensive security analysis has been conducted to evaluate the effectiveness of the proposed scheme. The obtained results have demonstrated the robustness of our algorithm against the most known types of attacks and have shown a significant improvement in term of execution time reduction compared to a similar existing JPEG 2000 images encryption scheme.
Spin dynamic simulations of solid effect DNP: the role of the relaxation superoperator (2014)

Relaxation plays a crucial role in the spin dynamics of dynamic nuclear polarisation. We review here two different strategies that have recently been used to incorporate relaxation in models to predict the spin dynamics of solid effect dynamic nuclear polarisation. A detailed explanation is provided on how the Lindblad–Kossakowski form of the master equation can be used to describe relaxation in a spin system. Fluctuations of the spin interactions with the environment as a cause of relaxation are discussed and it is demonstrated how the relaxation superoperator acting in Liouville space on the density operator can be derived in the Lindblad–Kossakowski form by averaging out non-secular terms in an appropriate interaction frame. Furthermore we provide a formalism for the derivation of the relaxation superoperator starting with a choice of a basis set in Hilbert space. We show that the differences in the prediction of the nuclear polarisation dynamics that are found for certain parameter choices arise from the use of different interaction frames in the two different strategies. In addition, we provide a summary of different relaxation mechanisms that need to be considered to obtain more realistic spin dynamic simulations of solid effect dynamic nuclear polarisation.

Interactions of intrathecally administered ziconotide, a selective blocker of neuronal N-type voltage-sensitive calcium channels, with morphine on nociception in rats (2000)

Ziconotide is a selective, potent and reversible blocker of neuronal N-type voltage-sensitive calcium channels (VSCCs). Morphine is an agonist of mu-opioid receptors and inhibits N-type VSCC channels via a G-protein coupling mechanism. Both agents are antinociceptive when they are administered intrathecally (spinally). The present study investigated the acute and chronic (7-day) interactions of intrathecally administered ziconotide and morphine on nociception in several animal models of pain. In the acute study, intrathecal bolus injections of morphine and ziconotide alone produced dose-dependent inhibition of formalin-induced tonic flinch responses and withdrawal responses to paw pressure. The combination of ziconotide and morphine produced an additive inhibition of formalin-induced tonic flinch responses and a significant leftward shift of the morphine dose-response curve in the paw pressure test. After chronic (7-day) intrathecal infusion, ziconotide enhanced morphine analgesia in the formalin test. In contrast, chronic intrathecal morphine infusion produced tolerance to analgesia, but did not affect ziconotide antinociception. Antinociception produced by ziconotide alone was the same as that observed when the compound was co-administered with morphine to morphine-tolerant rats. In the hot-plate and tail immersion tests, chronic intrathecal infusion of morphine lead to rapid tolerance whereas ziconotide produced sustained analgesia with no loss of potency throughout the infusion period. Although ziconotide in combination with morphine produced an apparent synergistic analgesic effects during the initial phase of continuous infusion, it did not prevent morphine tolerance to analgesia. These results demonstrate that (1) acute intrathecal administrations of ziconotide and morphine produce additive or synergistic analgesic effects; (2) chronic intrathecal morphine infusion results in tolerance to analgesia but does not produce cross-tolerance to ziconotide; (3) chronic intrathecal ziconotide administration produces neither tolerance nor cross-tolerance to morphine analgesia; (4) intrathecal ziconotide does not prevent or reverse morphine tolerance.
Reliability Analysis of a Suspension Bridge Affected by Hydrogen Induced Cracking Based upon Response Surface Method (2009)

This paper deals with the Hydrogen Induced Cracking (HIC) of wires in a cable of a suspension bridge. The main objective is to compare the safety of a bridge system locally and globally. In a deterministic analysis stage, HIC in cable wires is calculated in order to evaluate the local safety of the main cable of suspension bridge. In the local analysis, a decoupling technique has been developed for the evaluation of crack propagations in a wire section driven by the hydrogen diffusion to a wire section, in terms of two 2-dimensional finite element models. One is for the fracture analysis in a longitudinal section, and the other is for a hydrogen diffusion model in a horizontal section. In a stochastic analysis stage, an ultimate limit state function for the cracking in cable wires is considered for the local safety of main cable. Using the ultimate limit state, the reliability of time-dependent and crack depth-dependent HIC of a cable wire has been calculated in component and parallel system reliability analysis. Globally, a serviceability limit state based on the global responses of a stiffening girder is also evaluated. Based on the observed difference of safeties between the global and local behaviors of the suspension bridge system, the proposed solutions are discussed.
Remote hydrogen–nitrogen plasma chemical vapor deposition from a tetramethyldisilazane source. Part 1. Mechanism of the process, structure and surface morphology of deposited amorphous hydrogenated silicon carbonitride filmsElectronic supplementary information (ESI) available: deconvoluted emission and IR spectra of a-Si–N–C–H films. See http://www.rsc.org/suppdata/jm/b2/b211415c/ (2003)

Amorphous hydrogenated silicon carbonitride films were produced by remote plasma chemical vapor deposition (RP-CVD) from 1,1,3,3-tetramethyldisilazane (TMDSN) as the single-source compound using a H2–N2 upstream-gas-mixture for plasma generation. The reactivity of particular TMDSN bonds in the RP-CVD initiation step has been examined using a hexamethyldisilazane model compound in the deposition experiments. The active species contributing to RP-CVD were identified by optical emission spectroscopic analysis of the plasma region. The films were examined using Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and atomic force microscopy. The effect of N2 content in the H2–N2 upstream-gas-mixture on plasma generation of the active species, growth rate, chemical structure, and surface morphology of the resulting films is reported.

Results for the Nucleus multiple-electrode cochlear implant in two children [Abstract] (1988)

Two males, 9 years 10 months (CHILD 1) and 5 years 5 months (CHILD 2) at time of surgery, were implanted with the Nucleus multiple-electrode cochlear implant. Both patients were deafened as a result of meningitis in their third year. Assessments of speech perception, speech production and language skills were undertaken at regular intervals, pre and post operatively. For both patients in the audition alone condition, some speech perception post operative scores were significantly higher than pre operative scores and progressive improvements in scores over successive post operative data collection times were seen. Significant differences between the visual alone and auditory-visual condition scores were also observed for CHILD 1 post operatively. Speech production post operative scores were significantly higher than pre operative scores for both patients. The receptive vocabulary scores for both patients improved at a higher rate than that of age-matched normal children. The acquisition of expressive and receptive language skills for CHILD 2 was at a higher rate than that of age-matched children. Differences in the results between the two patients were seen, and this may be related to age and duration of deafness.
Detection of chemical agents, precursors and by-products using ion trap technology (1994)

The utility of a new field portable ion trap-based instrument, the Generic Detector, for use in chemical weapons treaty verification is assessed. The ability of the instrument to detect targeted chemical agents, precursors and degradation products is examined. Instrumental characteristics (membrane vacuum interface, ion pump, air buffer gas) which resulted from, the reduction in size of the instrument are evaluated as to their impact on the detection limits for these selected compounds. Detection limits in the low nanogram range are obtainable for most of the chemical agents, precursors and by-products using both GC/MS and GC/MS/MS analysis.

NDT of Layered Structures Using Pulse-Thermography and THz-TDS Imaging (2018)

The nondestructive testing (NDT) techniques active thermography and terahertz time domain spectroscopy (THz-TDS) are both newcomers to the large range of established NDT methods: Both are contactless imaging techniques and well suited for analysing layered materials e.g. ceramic coatings, polymer laminates and glued materials. These two methods are compared for characterising ceramic coatings. Measurement results show these two methods are practicable and complimentary for NDT applications of layered structures. The pulse-thermography is suitable for fast screening inspection and THz-TDS imaging performs well for the detailed investigation of coatings and boundary variations.
Issues in performance certification for high-level automotive control software (2005)

High-level supervisory control software for automotive applications (e.g., drive-by-wire) presents many challenges to making performance guarantees, which are a necessary part of the software's certification for deployment. The features of such systems demand that a compositional, or modular, approach to reasoning about performance be devised and applied. We discuss one such analytical approach as an alternative to simulation and testing.
Sparse Gaussian process regression for compliant, real-time robot control (2015)

Sparse Gaussian process (GP) models provide an efficient way to perform regression on large data sets. The key idea is to select a representative subset of the available training data, which induces the sparse GP model approximation. In the past, a variety of selection criteria for GP approximation have been proposed, but they either lack accuracy or suffer from high computational costs. In this paper, we introduce a novel and straightforward criterion for successive selection of training points used for GP model approximation. The proposed algorithm allows a fast and efficient selection of training points, while being competitive in learning performance. As evaluation, we employ our approach in learning inverse dynamics models for robot control using very large data sets (e.g. 500.000 samples). It is demonstrated in experiments that our approximated GP model is sufficiently fast for real-time prediction in robot control. Comparisons with other state-of-the-art approximation techniques show that our proposed approach is significantly faster, while being competitive to generalization accuracy.

Elevated expression of ACE2 in tumor-adjacent normal tissues of cancer patients (2020)

Abstract The rapidly developing COVID-19 pandemic has raised a concern that cancer patients may have increased susceptibility to SARS-CoV-2 infection. This discussion has mostly focused on therapy-induced immune suppression. Here, we examined the expression patterns of ACE2 , the receptor through which SARX-CoV2 enters human cells, and found that ACE2 mRNA levels are elevated in tumor-adjacent normal tissues of cancer patients, including in normal-adjacent lung tissues of lung cancer patients. These observations raise the possibility that the elevated COVID-19 risk of cancer patients may not be limited to those undergoing immune-suppressing treatment.
A thermoeconomic indicator for the sustainable development with social considerations (2021)

Abstract The United Nations action plan Agenda 21 has represented a milestone toward Sustainable Development. On its 40th Chapter, it is introduced the requirement to dispose of an accurate and continuous collection of information, essential for decision-making. Besides bridging the data gap and improving the information availability, it is highlighted the need to dispose of sustainable development indicators, in order to assess and monitor the performances of countries toward sustainability. In this paper, we develop an improvement of a new indicator, recently introduced linking environmental anthropic footprint and social and industrial targets. Here, we suggest a link with the Income Index, in order to consider also a condition of people well-being. Our results consists in an improvement of the present approaches to sustainability; indeed, we link the socio-economic considerations, quantified by the Income Index and the Human Development Index, to the engineering approach to optimization, introducing the thermodynamic quantity entropy generation, related to irreversibility. In this way, two different new indicators are introduced, the Thermodynamic Income Index and the Thermodynamic Human Development Index, which quantitatively express a new viewpoint, which goes beyond the dichotomy between socio-economic considerations on one hand and engineering and scientific approach to sustainability on the other one. So, the result leads to a unified tool useful for the designing of new policies and interventions for a sustainable development for the next generations.
Performance and Energy Modeling for Cooperative Hybrid Computing (2014)

Accelerator-based heterogeneous systems can provide high performance and energy efficiency, both of which are key design goals in high performance computing. To fully realize the potential of heterogeneous architectures, software must optimally exploit the hosts' and accelerators' processing and power-saving capabilities. Yet, previous studies mainly focus on using hosts and accelerators to boost application performance. Power-saving features to improve the energy efficiency of parallel programs, such as Dynamic Voltage and Frequency Scaling (DVFS), remain largely unexplored. Recognizing that energy efficiency is a different objective than performance and should therefore be independently pursued, we study how to judiciously distribute computation between hosts and accelerators for energy optimization. We further explore energy-saving scheduling in combination with computation distribution for even larger gains. Moreover, we present PEACH, an analytical model for Performance and Energy Aware Cooperative Hybrid computing. With just a few system- and application-dependent parameters, PEACH accurately captures the performance and energy impact of computation distribution and energy-saving scheduling to quickly identify the optimal coupled strategy for achieving the best performance or the lowest energy consumption. PEACH thus eliminates the need for extensive profiling and measurement. Experimental results from two GPU-accelerated heterogeneous systems show that PEACH predicts the performance and energy of the studied codes with less than 3% error and successfully identifies the optimal strategy for a given objective.
