Exploiting Mapping Diversity for Enhancing Security at Physical Layer in the Internet of Things (2018)

Application of Internet of Things (IoT) in health, defense, banking, and other confidential information transfer urges the need for secure IoT. As most of the IoT devices are resource-limited (antennas, bandwidth, energy), securing the information transfer has always been a challenge. Looking at a solution for enhancing the security of single antenna, single carrier, energy efficient devices, we propose a novel scheme, channel-based mapping diversity. This scheme uses the inherent randomness of the wireless channel and multiple mappings available for an M-ary phase shift keying constellation in confusing an eavesdropper. When the legitimate and the eavesdropper channels are independent of each other, it is shown that a symbol error rate (SER) of (M-1)/ M is induced at the eavesdropper. Whereas, when the channels are correlated, optimal and suboptimal strategies at source and eavesdropper are derived for their respective optimal performances. Further, a closed-form expression for a lower-bound on the SER at the eavesdropper is derived. Simulation results show that for the correlated case, as SNR at the eavesdropper increases, SER initially decreases, later saturates to a relatively high SER, hence making the job of the eavesdropper difficult in getting the legitimate data. Furthermore, the effect of the correlation is more pronounced on SER at higher levels of correlation. This indicates that for practical correlation scenarios, SER is high enough to confuse the eavesdropper.
Quantitative measurement of gas pressure drop along T-shaped micro channels by interferometry (2012)

The study of gas flows in microchannels has received considerably more attention in the literature from a simulation perspective than an experimental. The majority of the experimental work has emphasis on the global measurements at the inlet or exit of the microchannel instead locally along it. In this paper some efforts were made to measure the pressure drop along T-shaped micro channel by using interferometry. The two side channels were served as gas entrances and they were both open to air and the channel outlet was being vacuumed during experiments. A Mach-Zehnder interference microscopy was built for the measurement of gas pressure drop along the mixing channel. Some points along the mixing channel were selected for interferometric measurements. Simulations were first developed in unsteady condition by using Ansys Fluent to verify the nonexistence of transient phenomena of gas flow in the defined condition and then run again in steady condition to get the theoretical pressure drop that was would be used for comparison with experimental results.
Investigation of Coupled Lateral and Torsional Vibrations of a Cracked Rotor Under Radial Load (2007)

A practical cracked rotor model with two disks representing a turbine and generator is studied using a four degree of freedom model; two transverse displacements and two torsional angular displacements. The differential equations of a rotor with a crack, unbalance, and constant radial force are first derived in detail using energy principles. The nonlinearities related with a “breathing” crack are incorporated, which distinguishes this paper from others studying stiffness anisotropy of a rotor with a similar rotor configuration. Through numerical simulations, this paper demonstrates the lateral-torsional coupling that occurs with a shaft crack and predicts torsional critical speed frequencies at fixed non-integer ratios of lateral to torsional natural frequency. The spectrum of the torsional vibration is shown to contain super-synchronous critical speeds related to the lateral natural frequency. The unique frequency response of the torsional motion predicted by this model could be employed for early detection of a cracked rotor.
Computerized restoration of a fossil cranium based on selective elimination of estimated taphonomic deformation (2022)

Abstract Objectives Due to taphonomic processes, fossils have often undergone plastic deformation. To correctly assess the morphological affinities of such specimens, the original antemortem shape of the deformed specimens must be reconstructed. Here we describe a method to mathematically isolate and selectively eliminate the taphonomic deformation of a fossil cranium for restoration of its original antemortem appearance, and apply this method to reconstruction of a cranium of Mesopithecus from the late Miocene of Greece. Materials and methods Three‐dimensional (3D) models of the fossil cranium and the crania of phylogenetically close extant species were generated, and 3D shape variations of the crania were analyzed based on anatomical and sliding semi‐landmarks. Using principal component analysis, we attempt to extract the taphonomic deformation component of the shape variation that is presumably orthogonal to the hyperplane describing interspecific variations of the intact crania of the extant species. Landmarks were repositioned so that the extracted taphonomic component is selectively eliminated. A thin‐plate spline was used to describe the 3D transformation from original and repositioned landmarks, and the entire surface of the fossil was restored. Results The proposed method successfully extracted and eliminated the component of the taphonomic deformation and enabled restoration of the original antemortem appearance of the deformed fossil cranium. Discussion Unlike conventional methodologies, the proposed method does not rely on the assumption of symmetry for correction of taphonomic deformation. Although some methodological limitations apply, the proposed method may contribute to improved accuracy, objectivity, and transparency in virtual reconstruction of deformed cranial fossils.
CD4+CD25highCD127low/-FoxP3+ Regulatory T-Cell Population in Acute Leukemias: A Review of the Literature (2019)

Regulatory T-cells (Tregs) are a very important subtype of lymphocytes when it comes to self-control in the human immunological system. Tregs are decisive not only in the protection against destruction of own tissues by autoimmune immunocompetent cells but also in the immunological answer to developing cancers. On the other hand, Tregs could be responsible for the progression of acute and chronic leukemias. In our study, we review publications available in the PUMED database concerning acute leukemia, with a particular emphasis on child's leukemias. The percentage of regulatory T-lymphocytes in peripheral blood and bone marrow was elevated compared to those in healthy individuals and correlated with progressive disease. Regulatory T-cells taken from children diagnosed with leukemia showed a higher suppressive capability, which was confirmed by detecting elevated levels of secreted IL-10 and TGF-beta. The possibility of pharmacological intervention in the self-control of the immunological system is now under extensive investigation in many human cancers. Presumably, Treg cells could be a vital part of targeted therapies. Routine Treg determination could be used to assess the severity of disease and prognosis in children with acute lymphoblastic leukemia. This proposition results from the fact that in some studies, higher percentage of Treg cells in peripheral blood was demonstrated. However, observations confirming these facts are scarce; thus, extrapolating them to the population of children with hematological malignancies needs to be verified in additional studies.
Teleoperation controller design using H/sub ∞/-optimization with application to motion-scaling (1996)

The design of a bilateral teleoperation controller is a nontrivial problem. The goal is to achieve a stable system with optimal performance in the possible presence of time delays, disturbances, uncertainties and/or measurement noise. In this paper, a general design strategy based on H/sub /spl infin// theory is presented. This approach allows a convenient means to trade off the optimization of various performance criteria and system robustness. The control approach is applied to a motion-scaling teleoperation system and simulations and experiments with the resulting controllers demonstrate that the strategy is effective.
Simulated bi-SQUID Arrays Performing Direction Finding (2015)

Abstract : One of the High Temperature Superconductor (HTS) bi-Superconducting Quantum Interference Device (SQUID) Array Fractional Wavelength Baseline Determination and Design Study team s goal was to determine whether the raw simulated output from an array of bi-superconducting quantum interference devices (bi-SQUIDs) could perform direction-finding (DF) tasks such as the angle of arrival (AoA), elevation, and polarization. First, we applied the multiple signal classification (MUSIC) algorithm on linearly polarized signals. We included multiple signals in the output both of the same frequency and different frequencies. Next, we explored a modified MUSIC algorithm called dimensionality reduction MUSIC (DR- MUSIC), which can handle elliptical or circular polarizations. Finally, we explored the six-element Poynting vector method.
Dispersion Sources for Compact Geometries on Microchips (1998)

Folding the separation channel in a microchip device generally introduces an additional geometrical contribution to analyte dispersion through lateral variations in both migration distance and field strength. The geometrical dispersion generated depends on the ratio of the analyte transverse diffusion time to the time that the analyte band spends traversing the turn. A one-dimensional model has been developed which predicts the amount of excess dispersion introduced by turns in microchip channels. This model accounts for migration length differences, field strength differences, and transverse diffusion effects and accurately describes the experimental data. The introduction of turns into the channel on a microchip is shown to reduce separation efficiency compared to the same separation length in a straight channel, especially for molecules with small diffusion coefficients. Several methods to reduce geometrical dispersion are examined including the manipulation of channel width and analyte velocity and the use of complementary pairs of turns.
A DSL for importing models in a requirements management system (2014)

Requirements are artefacts often described with text and models. It is important to manage traceability between requirements and other software artefacts, including designs and test cases, also often captured with specialized models. Some Requirements Management Systems (RMS) support traceability relationships, between (textual) requirements artefacts in the RMS and model artefacts created outside the RMS, through complex standards or proprietary solutions. This paper proposes a new Domain-Specific Language (DSL) for describing the concepts of a modeling language intended to be traced using an RMS, with tool support handling the import and re-import of models and of their traceability links. The Model Import DSL (MI-DSL) is supported by an Xtext-based editor and the automatic generation of an import library targeting a leading RMS, namely IBM Rational DOORS. The language and the tools are demonstrated for model import and evolution scenarios with two different modeling languages. This work contributes a simple yet reliable mechanism to define and support traceability between requirements and models from different tools.

Rapid Detection of Human Cytomegalovirus and Herpesvirus Hominis IgM Antibody by the Immunoperoxidase Technique (1977)

Immunoglobulin M (IgM) to human cytomegalovirus (CMV) and herpesvirus hominis (HVH, types 1 and 2) has been searched for in a group of patients with congenital and recent CMV and HVH infections and also in a group of patients with remote CMV and recurrent HVH infections, using the immunoperoxidase antibody technique (IPA) as compared to a technique using sucrose density gradient differential centrifugation. Both techniques detected the same positive samples. High IgM antibody titers (1:32-1:512) were observed in all cases of primary CMV and HVH infection, whereas low titers (1:8-1:16) were found in congenital infections. The IPA technique is sensitive, specific and useful for rapid diagnosis of recent and congenital CMV and HVH infections.
Harvesting Broadband Kinetic Impact Energy from Mechanical Triggering/Vibration and Water Waves (2014)

We invented a triboelectric nanogenerator (TENG) that is based on a wavy-structured Cu-Kapton-Cu film sandwiched between two flat nanostructured PTFE films for harvesting energy due to mechanical vibration/impacting/compressing using the triboelectrification effect. This structure design allows the TENG to be self-restorable after impact without the use of extra springs and converts direct impact into lateral sliding, which is proved to be a much more efficient friction mode for energy harvesting. The working mechanism has been elaborated using the capacitor model and finite-element simulation. Vibrational energy from 5 to 500 Hz has been harvested, and the generator's resonance frequency was determined to be ∼100 Hz at a broad full width at half-maximum of over 100 Hz, producing an open-circuit voltage of up to 72 V, a short-circuit current of up to 32 μA, and a peak power density of 0.4 W/m(2). Most importantly, the wavy structure of the TENG can be easily packaged for harvesting the impact energy from water waves, clearly establishing the principle for ocean wave energy harvesting. Considering the advantages of TENGs, such as cost-effectiveness, light weight, and easy scalability, this approach might open the possibility for obtaining green and sustainable energy from the ocean using nanostructured materials. Lastly, different ways of agitating water were studied to trigger the packaged TENG. By analyzing the output signals and their corresponding fast Fourier transform spectra, three ways of agitation were evidently distinguished from each other, demonstrating the potential of the TENG for hydrological analysis.
Water fluxes and encapsulation efficiency in double emulsions: impact of emulsification and osmotic pressure unbalance (2016)

We study the influence of the emulsification process on encapsulation efficiency of drugs in double water-in-oil-in-water emulsions. Two drugs were used, first vitamin B12 which can be considered as a model drug and secondly a suspension of Cydia pomonella Granulovirus (CpGV), a virus used in organic agriculture to protect fruits against the Carpocapse insect. Encapsulation is measured by classical UV-Vis spectroscopy method. Additionally we show that rheology is a useful tool to determine water exchanges during emulsification. In a two-step emulsification process, using rotor-stator mixers, encapsulation reaches high levels, close to 100% whatever the flowing regime. This encapsulation decreases only if two conditions are fulfilled simultaneously: (i) during the second emulsification step the flow is turbulent and (ii) it leads to excessive fragmentation inducing formation of too small drops. We also investigate the effect of a deliberate loss of osmotic pressure balance on the encapsulation and characterize the induced water fluxes. We show that encapsulation of vitamin B12 is not affected by the osmotic pressure unbalance, while water exchanges, if they exist, are very fast and aim at restoring equilibrium. As a consequence, the emulsification efficiency is not very sensitive to osmotic stresses provided that the interfaces resist mechanically.

Testing the Abrasion Resistance of Porous SiO2 Anti-reflection Coatings for Solar Cover Glass (2022)

The cover glass sheet on solar modules can cause reflection losses as well as soiling build-up. Reflection losses can be addressed with anti-reflection (AR) coatings, whilst soiling is removed by mechanical cleaning processes that are effective but can have adverse effects on surface coatings. In this work, multilayer broadband and commercial porous SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> AR coatings have been subject to abrasion testing that simulates the regular cleaning of solar modules in the field, using Felt Pad and CS-10 abradant materials. The Felt Pad abrasion has no impact on the multilayer coating, but caused visible damage to the porous SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> , increasing WAR from 5.97% to 6.75% after 100 cycles. After 50 and 100 abrasion cycles of CS-10, significant scratches are visible on the porous SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> coating, and the weighted average reflectance (WAR) of the coating increases from 5.97% to 7.08% after 100 cycles. The coating is fully removed in some abraded areas. The multilayer AR coating also experiences some damage after CS-10 abrasion, increasing WAR from 5.84% to 6.68%. Optical microscopy and Scanning Electron Microscopy (SEM) show the nature of the abrasion damage caused. Overall, the multilayer AR coating shows significantly higher abrasion resistance than the porous SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . Significant abrasion damage to porous SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> AR coatings is a major problem for solar asset managers resulting in long-term power losses.
NEONATAL TYPE OF ARGININOSUCCINATE SYNTHETASE DEFICIENCY (1985)

Two autopsy cases of neonatal argininosuccinate synthetase (ASS) deficiency demonstrating the particular histological changes of the liver are presented. Case 1 was a female infant with elevated blood ammonia and citrulline. The patient died of sepsis at nineteen days after birth. Autopsy revealed hematomas in bilateral cerebral hemispheres and a yellow liver parenchyma. Histologically, the cerebrum showed diffuse astrogliosis with Alzheimer type II cell and swollen cytoplasm. Status spongiosus and gliosis were observed in the subthalamic and pontine nuclei. The liver demonstrated fatty degeneration and wide portal space with bile duct proliferation and inflammatory cell infiltration. The ASS activities in the liver and the kidneys were not detected. Case 2 was a female infant who died of respiratory distress twenty-four days after birth. Autopsy revealed hematomas in the bilateral cerebral ventricles and a liver with yellow parenchyma. Histologically, there was destruction of arrangement in the cerebrum and cerebellum together with marked decrease of nerve cells with gliosis and phagocytosis. The liver showed mild fatty degeneration and wide portal space accompanied by bile duct proliferation and inflammatory cell infiltration. The ASS activities in the liver and kidneys were not detected.
