Securing Large-Scale D2D Networks Using Covert Communication and Friendly Jamming (2022)

We exploit both covert communication and friendly jamming to propose a friendly jamming-assisted covert communication and use it to doubly secure a large-scale device-to-device (D2D) network against eavesdroppers (i.e., wardens). The D2D transmitters defend against the wardens by: 1) hiding their transmissions with enhanced covert communication, and 2) leveraging friendly jamming to ensure information secrecy even if the D2D transmissions are detected. We model the combat between the wardens and the D2D network (the transmitters and the friendly jammers) as a two-stage Stackelberg game. Therein, the wardens are the followers at the lower stage aiming to minimize their detection errors, and the D2D network is the leader at the upper stage aiming to maximize its utility (in terms of link reliability and communication security) subject to the constraint on communication covertness. We apply stochastic geometry to model the network spatial configuration so as to conduct a system-level study. We develop a bi-level optimization algorithm to search for the equilibrium of the proposed Stackelberg game based on the successive convex approximation (SCA) method and Rosenbrock method. Numerical results reveal interesting insights. We observe that without the assistance from the jammers, it is difficult to achieve covert communication on D2D transmission. Moreover, we illustrate the advantages of the proposed friendly jamming-assisted covert communication by comparing it with the information-theoretical secrecy approach in terms of the secure communication probability and network utility.
Endovascular Treatment of Post-Subarachnoid Hemorrhage Vasospasm (2007)

Carotid cavernous fistula (CCF) is an abnormal communication between the internal carotid artery (ICA) and the cavernous sinus. Direct CCF represents one specific form of CCF with high-pressure arterial blood entering the low-pressure venous cavernous sinus, most commonly via a single hole in the cavernous segment of the ICA (Fig. 1). In contrast, the other variety of CCF has been coined an ‘‘indirect’’ CCF and is characterized by a nidus of dural arterioles (1-3). Indirect CCF is described more fully in another chapter.
Cast Body Nodes for 2016 Acura NSX (2015)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Ablation casting is an emerging technology which combines traditional sand molding techniques with rapid cooling due to the use of a water soluble binder. High cooling rates and control of solidification direction allows for exceptional mechanical properties and complex shapes. Through the use of ablation, six different body node castings have been manufactured for the 2016 NSX aluminum space frame. The high mechanical properties allowed these castings to be integrated into the crash structure for energy absorption. Using the traditional casting alloy A356, target mechanical properties were 190 Mpa Yield Strength, 280 Mpa Tensile Strength and 12% min elongation. The high elongation was achieved due to the refined eutectic microstructure produced by high cooling rates. The eutectic microstructure produced by ablation was found to be Level 5 or 6 on the AFS scale. Light weighting could also be achieved when compared to traditional GDC castings. By using sand molds instead of steel dies, the nominal wall thickness was set to 4 mm instead of 5-6 mm when using traditional gravity die casting. Further light weighting was achieved by using sand cores to create complex hollow internal sections. The combination of high properties and hollow shapes made ablation cast nodes ideal for a lightweight space frame structure.&lt;/div&gt;&lt;/div&gt;
Rotavirus Nonstructural Protein NSP5 Interacts with Major Core Protein VP2 (2003)

Rotavirus is a nonenveloped virus with a three-layered capsid. The inner layer, made of VP2, encloses the genomic RNA and two minor proteins, VP1 and VP3, with which it forms the viral core. Core assembly is coupled with RNA viral replication and takes place in definite cellular structures termed viroplasms. Replication and encapsidation mechanisms are still not fully understood, and little information is available about the intermolecular interactions that may exist among the viroplasmic proteins. NSP2 and NSP5 are two nonstructural viroplasmic proteins that have been shown to interact with each other. They have also been found to be associated with precore replication intermediates that are precursors of the viral core. In this study, we show that NSP5 interacts with VP2 in infected cells. This interaction was demonstrated with recombinant proteins expressed from baculovirus recombinants or in bacterial systems. NSP5-VP2 interaction also affects the stability of VP6 bound to VP2 assemblies. The data presented showed evidence, for the first time, of an interaction between VP2 and a nonstructural rotavirus protein. Published data and the interaction demonstrated here suggest a possible role for NSP5 as an adapter between NSP2 and the replication complex VP2-VP1-VP3 in core assembly and RNA encapsidation, modulating the role of NSP2 as a molecular motor involved in the packaging of viral mRNA.
Quantum electron ad optoelectonic devices (1992)

Recent advances in quantum devices are reviewed. Transistors based on resonant tunneling promise to greatly reduce circuit complexity in certain analog and digital applications. Prototype multiplier and parity generator circuits which illustrate this point have been demonstrated. The final section of this paper discusses recent results on AlGaAs/GaAs quantum well infrared photodetectors (QWIP) and focal plane arrays and the potential of this technology vis-a-vis HgCdTe based detectors at ?~10 ?m.
Access rights analysis for Java (2002)

Java 2 has a security architecture that protects systems from unauthorized access by mobile or statically configured code. The problem is in manually determining the set of security access rights required to execute a library or application. The commonly used strategy is to execute the code, note authorization failures, allocate additional access rights, and test again. This process iterates until the code successfully runs for the test cases in hand. Test cases usually do not cover all paths through the code, so failures can occur in deployed systems. Conversely, a broad set of access rights is allocated to the code to prevent authorization failures from occurring. However, this often leads to a violation of the "Principle of Least Privilege"This paper presents a technique for computing the access rights requirements by using a context sensitive, flow sensitive, interprocedural data flow analysis. By using this analysis, we compute at each program point the set of access rights required by the code. We model features such as multi-threading, implicitly defined security policies, the semantics of the Permission.implies method and generation of a security policy description. We implemented the algorithms and present the results of our analysis on a set of programs. While the analysis techniques described in this paper are in the context of Java code, the basic techniques are applicable to access rights analysis issues in non-Java-based systems.

SMC (2017)

We address the problem of determining the satisfiability of a Boolean combination of convex constraints over the real numbers, which is common in the context of hybrid system verification and control. We first show that a special type of logic formulas, termed monotone Satisfiability Modulo Convex (SMC) formulas, is the most general class of formulas over Boolean and nonlinear real predicates that reduce to convex programs for any satisfying assignment of the Boolean variables. For this class of formulas, we develop a new satisfiability modulo convex optimization procedure that uses a lazy combination of SAT solving and convex programming to provide a satisfying assignment or determine that the formula is unsatisfiable. Our approach can then leverage the efficiency and the formal guarantees of state-of-the-art algorithms in both the Boolean and convex analysis domains. A key step in lazy satisfiability solving is the generation of succinct infeasibility proofs that can support conflict-driven learning and decrease the number of iterations between the SAT and the theory solver. For this purpose, we propose a suite of algorithms that can trade complexity with the minimality of the generated infeasibility certificates. Remarkably, we show that a minimal infeasibility certificate can be generated by simply solving one convex program for a sub-class of SMC formulas, namely ordered positive unate SMC formulas, that have additional monotonicity properties. Perhaps surprisingly, ordered positive unate formulas appear themselves very frequently in a variety of practical applications. By exploiting the properties of monotone SMC formulas, we can then build and demonstrate effective and scalable decision procedures for problems in hybrid system verification and control, including secure state estimation and robotic motion planning.
Mating disrupts morning anticipation in Drosophila melanogaster females (2022)

After mating, the physiology of Drosophila females undergo several important changes, some of which are reflected in their rest-activity cycles. To explore the hypothesis that mating modifies the temporal organization of locomotor activity patterns, we recorded fly activity by a video tracking method. Monitoring rest-activity patterns under light/dark (LD) cycles indicated that mated females lose their ability to anticipate the night-day transition, in stark contrast to males and virgins. This postmating response is mediated by the activation of the sex peptide receptor (SPR) mainly on pickpocket (ppk) expressing neurons, since reducing expression of this receptor in these neurons restores the ability to anticipate the LD transition in mated females. Furthermore, we provide evidence of connectivity between ppk+ neurons and the pigment-dispersing factor (PDF)-positive ventral lateral neurons (sLNv), which play a central role in the temporal organization of daily activity. Since PDF has been associated to the generation of the morning activity peak, we hypothesized that the mating signal could modulate PDF levels. Indeed, we confirm that mated females have reduced PDF levels at the dorsal protocerebrum; moreover, SPR downregulation in ppk+ neurons mimics PDF levels observed in males. In sum, our results are consistent with a model whereby mating-triggered signals reach clock neurons in the fly central nervous system to modulate the temporal organization of circadian behavior according to the needs of the new status.
Aphasia quality of life: reliability of the Italian version of SAQOL-39. (2004)

Our Italian version of SAQOL-39 seems suitable for clinical use. A multicentric study aiming to compare our data to original English ones is in progress.
Six-Port Radar Sensor for Remote Respiration Rate and Heartbeat Vital-Sign Monitoring (2013)

A novel remote respiration and heartbeat monitoring sensor is presented. The device is a monostatic radar based on a six-port interferometer operating a continuous-wave signal at 24 GHz and a radiated power of less than 3 μW . Minor mechanical movements of the patient's body caused by the respiration as well as heartbeat can be tracked by analyzing the phase modulation of the backscattered signal by means of microwave interferometry with the six-port network. High-distance measurement accuracy in the micrometer scale as well as low system complexity are the benefits of the six-port receiver. To verify the performance of the system, different body areas have been observed by the six-port radar. The proposed system has been tested and validated by measurement results.
Soil-specific limitations for access and analysis of soil microbial communities by metagenomics (2011)

Metagenomics approaches represent an important way to acquire information on the microbial communities present in complex environments like soil. However, to what extent do these approaches provide us with a true picture of soil microbial diversity? Soil is a challenging environment to work with. Its physicochemical properties affect microbial distributions inside the soil matrix, metagenome extraction and its subsequent analyses. To better understand the bias inherent to soil metagenome 'processing', we focus on soil physicochemical properties and their effects on the perceived bacterial distribution. In the light of this information, each step of soil metagenome processing is then discussed, with an emphasis on strategies for optimal soil sampling. Then, the interaction of cells and DNA with the soil matrix and the consequences for microbial DNA extraction are examined. Soil DNA extraction methods are compared and the veracity of the microbial profiles obtained is discussed. Finally, soil metagenomic sequence analysis and exploitation methods are reviewed.
Prevalence of allergen sensitization among patients with allergic diseases in Guangzhou, Southern China: a four-year observational study (2014)

Der pteronyssinus, Der farinae, cow's milk, and eggs are major allergens in Guangzhou. Sensitization to eggs and cow's milk is more common at younger age, and then gives place to the increasing prevalence of sensitization to Der pteronyssinus and Der farinae at older age. Such a sequence of events may be a result of allergy march. Knowledge on the prevalence of allergen sensitization in different age groups would help early diagnosis and intervention of allergic diseases in this large geographical region.
Resistance in Tomato and Other Lycopersicon Species to Insect and Mite Pests (2006)

Current world agricultural production is largely limited by environmental stresses (Boyer 1982). It is estimated that only 10% of the world’s arable land may be free of stress (Dudal 1976). Extreme temperatures, drought, soil salinity, and nutrient imbalances (including mineral toxicities and deficiencies) are among the major environmental constraints to crop production worldwide. Most plant breeding programs have focused on the development of cultivars with high yield potential in favorable (i.e., nonstress) environments. Such efforts have been extremely successful in improving the efficiency of crop production per unit area thus resulting in significant increase in total agricultural production (Duvick 1986). However, with the rapid increase in human population there is a greater need for food production, and with the increasing diminution in natural resources, and arable lands, greater efforts must be made to increasing crop productivity under stressful agricultural environments and bringing marginal lands under cultivation. Marginal agricultural environments could be enriched by growing stress tolerant plants to increase yields, which is an important step toward solving the problem of feeding the world’s growing population.
Prostaglandin D2 causes accumulation of eosinophils in the lumen of the dog trachea (1989)

Prostaglandin D2 (PGD2), the major product of arachidonic acid metabolism via the cyclooxygenase pathway in most mast cells, is present in the airways of atopic asthmatic patients after antigen challenge. Because eosinophilia is characteristic of asthma, we asked whether PGD2 causes eosinophils to accumulate in the airways in vivo. Using an endotracheal tube with two inflatable balloons we isolated a segment of trachea in four anesthetized mechanically ventilated dogs, and we superfused this segment with either a control solution (Hanks' balanced salt solution and antibiotics) or solution containing PGD2 (10(-6) M). Total and differential cell counts were determined at base line and every hour for 4 h during the study. PGD2 caused eosinophil accumulation in the trachea [7.0 +/- 3.4, 28.7 +/- 17.8, 33.7 +/- 13.6, and 35.4 +/- 10.7 (SD) cells/cm2 trachea after 1, 2, 3, and 4 h, respectively, P less than 0.05 vs. controls] but had no significant effect on neutrophil accumulation. The effect of PGD2 on eosinophil accumulation was significantly inhibited by the prostaglandin receptor antagonist SKF 88046 (5 mg/kg iv). We conclude that PGD2 is a selective stimulus that causes accumulation of eosinophils in the tracheal lumen of dogs in vivo.
BLUE VERSUS GRAY: POTENTIAL HEALTH BENEFITS OF BLUEBERRIES FOR SUCCESSFUL AGING (2017)

Emerging evidence from both preclinical and clinical studies have generated evidence of the potential health benefits of consuming blueberries (BBs). This fruit contains among the highest levels of polyphenols identified that provide highly effective antioxidant protection in addition to activating a wide range of other stress signaling pathways directly impacting health. The challenge now is to identify mechanisms through which BBs mediate their health benefits. Based on a wide range of preclinical and clinical studies, D Ingram (LSU, USA) will chair this symposium to review progress in assessing the health effects of BBs to promote successful aging. A Rodriguez-Mateos (U. Duesseldorf, GERMANY) will review studies examining the cardiovascular effects of BBs. CM Williams (U Reading, UK) will examine the cognitive effects of BB consumption in children and adults. B Shukitt-Hale (USDA/Tufts U, USA) will present data examining the effects of BB on motor and cognitive performance and brain inflammation in older adults. Y Desjardins (Laval U, CANADA) will present findings highlighting effects of BB consumption on the microbiome and its impact upon various health parameters. D Ingram will conclude with a talk focused on the concept of “hormesis.” Specifically, he will present data showing that berry fruits provide long-term protection against oxidative stress because they initially generate an essential mild oxidative stress.
The effect of oxygen incorporation in semi-insulating (AlxGa1−x)yIn1−yP (1992)

Oxygen-doped, semi-insulating layers of (AlxGa1−x)yIn1−yP with x=0.4 were grown on GaAs using organometallic vapor phase epitaxy (OMVPE). Secondary-ion mass spectrometry measurements show that the oxygen incorporation is proportional to the flow rate of O2 into the OMVPE reactor. Two-terminal metal-insulator-semiconductor devices were fabricated and used to evaluate the electrical characteristics of the (AlxGa1−x)yIn1−yP. Traps into the (AlxGa1−x)yIn1−yP bulk behave like DX centers, and are believed to be related to residual Si contamination. Increasing the oxygen concentration in the (AlxGa1−x)yIn1−yP layer decreases the trap concentration by the formation of oxygen complexes with the Si atoms.
A link-to-system level interface for B3G scenarios (2010)

Advanced simulation tools have taken a lot of attention for development and analysis of new and existing protocols and technologies in wireless communications. The huge amount of information, protocols and techniques to be analysed make however their implementation difficult in one simulator. It is thus of paramount importance to define a common interface between the different layers in order to simplify the implementation task but guaranteeing also the confidence of the obtained results. This paper provides a complete specification of the system level simulation envisaged for Beyond 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> Generation (B3G) systems. The main idea of this paper is to explain how we could extract information from the link level simulation and to implement them in the system level simulation. Two particular cases are considered for the proof of concept in this work. The first one concerns the Spatial Division Multiple Access (SDMA) technique using positioning information. The second one concerns the use of the cooperative communications to improve the quality of service at the cell border.
New methodology on electro-thermal characterization and modeling of large power drivers using lateral PNP BJTs (2010)

This paper presents a new methodology to characterize and simulate the electro-thermal aspects of packaged power drivers using lateral bipolars. Maximum elevation of junction temperature due to the electrical power stress is sensed in the field of the drivers. Those measurements are further complemented by the transient interferometric mapping (TIM) inspection. For the first time a data driven segmented electro-thermal model is proposed to describe accurately the non-uniform current density and the thermal profile behavior of a large power driver.
Modulation of brainstem activity and connectivity by respiratory-gated auricular vagal afferent nerve stimulation in migraine patients (2017)

Migraine pathophysiology includes altered brainstem excitability, and recent neuromodulatory approaches aimed at controlling migraine episodes have targeted key brainstem relay and modulatory nuclei. In this study, we evaluated the impact of respiratory-gated auricular vagal afferent nerve stimulation (RAVANS), a novel neuromodulatory intervention based on an existing transcutaneous vagus nerve stimulation approach, in the modulation of brainstem activity and connectivity in migraine patients. We applied 3T-functional magnetic resonance imaging with improved in-plane spatial resolution (2.62 × 2.62 mm) in episodic migraine (interictal) and age- and sex-matched healthy controls to evaluate brain response to RAVANS (gated to either inhalation or exhalation) and sham stimulation. We further investigated RAVANS modulation of tactile trigeminal sensory afference response in the brainstem using air-puff stimulation directed to the forehead during functional magnetic resonance imaging. Compared with sham and inhalatory-gated RAVANS (iRAVANS), exhalatory-gated RAVANS (eRAVANS) activated an ipsilateral pontomedullary region consistent with nucleus tractus solitarii (NTS). During eRAVANS, NTS connectivity was increased to anterior insula and anterior midcingulate cortex, compared with both sham and iRAVANS, in migraine patients. Increased connectivity was inversely correlated with relative time to the next migraine attack, suggesting clinical relevance to this change in connectivity. Poststimulation effects were also noted immediately after eRAVANS, as we found increased activation in putative pontine serotonergic (ie, nucleus raphe centralis) and noradrenergic (ie, locus coeruleus) nuclei in response to trigeminal sensory afference. Regulation of activity and connectivity of brainstem and cortical regions involved in serotonergic and noradrenergic regulation and pain modulation may constitute an underlying mechanism supporting beneficial clinical outcomes for eRAVANS applied for episodic migraine.
