Design of Infrared SPR Sensor Based on Bimetallic Nanowire Gratings on Plastic Optical Fiber Surface (2014)

In this paper, a bilayer metallic grating with pitch of 1 μm on the flank of a cylindrical plastic optical fiber was proposed as a novel optical sensor. Surface plasmon resonance excited by this structure for refractive index sensing is investigated by finite difference time domain methods. A theoretical sensitivity of 643.75 nm/RIU is obtained, where the wavelength of the resonant sharp dip is obviously shifted from 1.398 μm to 1.501 μm for surrounding refractive index increased from 1.33 to 1.49. Several factors which affect the accuracy of the device, such as the polarization state of the incident light, grating pitch, and refractive index of the sensing medium, are discussed. The successful fabrication of the grating indicates the feasibility of the devices. The sensor is expected to have potential applications in the chemical, biomedical, environmental safety, and food safety industries as well as in many other aspects.
Meso-Scale Digital Materials: Modular, Reconfigurable, Lattice-Based Structures (2016)

We present a modular, reconfigurable system for building large structures. This system uses discrete lattice elements, called digital materials, to reversibly assemble ultralight structures that are 99.7% air and yet maintain sufficient specific stiffness for a variety of structural applications and loading scenarios. Design, manufacturing, and characterization of modular building blocks are described, including struts, nodes, joints, and build strategies. Simple case studies are shown using the same building blocks in three different scenarios: a bridge, a boat, and a shelter. Field implementation and demonstration is supplemented by experimental data and numerical simulation. A simplified approach for analyzing these structures is presented which shows good agreement with experimental results.
NO release regulated by doxorubicin as the green light-harvesting antenna (2020)

We report for the first time a NO photodonor (NOPD) operating with the widely used chemotherapeutic agent doxorubicin (DOX) as the light-harvesting antenna. This permits NO uncaging from an N-nitroso appendage upon selective excitation of DOX with highly biocompatible green light, without precluding its typical red emission. This NOPD effectively binds DNA and photodelivers NO nearby, representing an intriguing candidate for potential multimodal therapeutic applications based on the combination of DOX and NO.
A spatio-temporal clustering method using real-time motion analysis on event-based 3D vision (2010)

This paper proposes a method for clustering asynchronous events generated upon scene activities by a dynamic 3D vision system. The inherent detection of moving objects offered by the dynamic stereo vision system comprising a pair of dynamic vision sensors allows event-based stereo vision in real-time and a 3D representation of moving objects. The clustering method exploits the sparse spatio-temporal representation of sensor's events for real-time detection and separation between moving objects. The method makes use of density and distance metrics for clustering asynchronous events generated by scene dynamics (changes in the scene). It has been evaluated on clustering the events of moving persons across the sensor field of view. Tests on real scenarios with more than 100 persons show that the resulting asynchronous events can be successfully clustered and the persons can be detected.
A study of near-field imaging and diagnostic applications of surface equivalent current methods (2018)

The utilization of surface equivalent current (SEC) methods in near-field imaging and diagnostics of flat scatterers with fine details is discussed. Of special interest is the ability to identify and locate electrically small physical changes on the scatterers by analyzing the equivalent surface current densities obtained by transforming the observed near fields. Using two test objects as scattering targets for an incident plane wave at 77 GHz, it is shown that sub-wavelength physical changes can even be localized using SEC methods. Finally, the need for an appropriate excitation method and measurement setup is discussed in the light of experimental results.

Design Method for Online Totally Self-Checking Comparators Implementable on FPGAs (2020)

In this article, we propose a method for designing online totally self-checking (TSC) comparators for TSC systems implementable on field-programmable gate arrays (FPGAs). This method can be used to conduct exhaustive online diagnostics of each lookup table (LUT), which involves mapping the fundamental components of the comparator, with a small number of test patterns by directly measuring output of each LUT. Our method drastically reduces the number of test patterns for exhaustive diagnosis on the order of the input number n [O(n)] (n is the input number to the comparator) while maintaining 100% coverage, even if we only know the specifications of the LUT without knowing its detailed structure. FPGAs will be easily applicable to systems that require high dependability. To confirm the soft error rate (SER) in a static random-access memory (SRAM)-based FPGA, we also conducted an experiment involving a single-event upset (SEU) caused by neutron radiation. For this experiment, we designed an FPGA implementation of 1575 identical dual-modular-redundant TSC comparators. The experiment was conducted for 10.4 h, and 34 errors were observed regarding such failures in comparator function. The evaluated SER for the TSC comparator with the proposed method was 0.055 FIT at sea level of New York City.
Thin-film silicon solar cells for space applications: radiation hardness and applications for an integrated Solant (solar cell-antenna) module (2002)

A new device called "Solant" (for SOLar cell-ANTenna) is presented in this paper. It is a combination of thin-film amorphous silicon solar cells and flat printed antennas. A proton irradiation campaign has also been carried out on a series of n-i-p amorphous and p-i-n micromorph [microcrystalline (/spl mu/c-Si:H) and amorphous (a-Si:H)] silicon tandem solar cells. The effect of thermal annealing on solar cells degraded by proton irradiation is investigated.
THE ASSOCIATION OF TELOMERES LENGTH AND CORONARY ARTERY DISEASE: A META-ANALYSIS (2012)

Objectives Telomeres, the end of the chromosomes, which play a crucial role in retaining the stability and integrity of the chromosome, is linked with several aging-related diseases. A number of studies confirmed its relevance with coronary artery disease. However, the dispute exists. Methods The telomere length data from 13 publications consists of 1985 cases and 3435 controls are pooled in a meta-analysis to assess the association between coronary artery disease and telomere length. Results Telomere length is associated with coronary artery disease (WMD=−0.26, 95% CI −0.29 to −0.23). And the association between the telomere length and CAD was statistically significant in studies from European-American countries (WMD=−0.25, 95% CI −0.29 to −0.22), and Asian countries (WMD=−0.83, 95% CI −1.21 to −0.45). There was no publication bias in this meta-analysis Conclusions Telomere length is associated with coronary artery disease by statistical evidence.
Localization and manipulation of small parts using GelSight tactile sensing (2014)

Robust manipulation and insertion of small parts can be challenging because of the small tolerances typically involved. The key to robust control of these kinds of manipulation interactions is accurate tracking and control of the parts involved. Typically, this is accomplished using visual servoing or force-based control. However, these approaches have drawbacks. Instead, we propose a new approach that uses tactile sensing to accurately localize the pose of a part grasped in the robot hand. Using a feature-based matching technique in conjunction with a newly developed tactile sensing technology known as GelSight that has much higher resolution than competing methods, we synthesize high-resolution height maps of object surfaces. As a result of these high-resolution tactile maps, we are able to localize small parts held in a robot hand very accurately. We quantify localization accuracy in benchtop experiments and experimentally demonstrate the practicality of the approach in the context of a small parts insertion problem.

Size-controlling of Cu2ZnSnS4 nanoparticles: Effects of stabilizing/reducing agents on material properties (2020)

In this study, Cu2ZnSnS4 (CZTS) nanoparticles with an average size in a range of 10–36 nm were synthesized via solvothermal synthesis using different amounts of polyvinylpyrrolidone (PVP, 3, 5, 7, and 9 mg/mL) stabilizing agent. The effect of the amount of PVP on the CZTS nanoparticles’ structure, phase formation, composition, morphology, and opto-electronic properties were studied using XRD, UV–vis spectroscopy, TEM, FE-SEM, and Raman spectroscopy. Raman spectroscopy and XRD confirmed the formation of a pure kieserite phase with high crystallinity. The nanoparticles exhibited a strong preferential orientation along the [1 1 2] crystallographic plane. Using PVP stabilizer at a concentration of 9 mg/mL, a nearly stoichiometric ratio of 2:1:1:4 was achieved. The UV–vis absorption spectroscopy measurements showed an absorption coefficient exceeding 104 cm−1 in the visible light region and energy gap of CZTS nanoparticles between 1.59 eV and 1.82 eV, which is close to the optimum bandgap value for solar cell conversion devices. The TEM study revealed good CZTS nanoparticles crystals with diameters of approximately 10–40 nm depending on the stabilizing agent concentration. Solar cell devices with Al/ZnO: Al/ZnO/CdS/CZTS/Mo structures prepared with CZTS synthesized using PVP stabilizer at a concentration of 9 mg/mL had a maximum Jsc = 9.83 mA/cm2, Voc = 0. 453 V, fill factor = 61.1%, and efficiency of 2.7%.
A Detection and Mitigation Model for PTP Delay Attack in an IEC 61850 Substation (2016)

Smart grid applications demand the availability of a reliable and accurate time signal. Measurements and events need to be correctly aligned to enable proper actions and decisions. Precision time protocol (PTP) is the favored protocol for time distribution across smart grid domains. The correct functionality of PTP is of paramount importance and its security is of high priority. To harden its security, detection, and prevention mechanisms against attacks targeting PTP are needed. In this paper, we propose detection and mitigation mechanisms against the known PTP delay attack. We apply model checking to quantify the effect of the delay attack. Moreover, the validity of the proposed mechanism is formally proven. The suggested approach is tested on a physical system. The collected results support the usefulness of the mechanism in detecting the delay attacks targeting PTP, and preserving the system functionality.
Sound field analysis assuming a cuboid sound field and the same acoustic absorption medium. (2017)

In the design of the cabin such as a car and an agricultural machine, the construction machine, it is necessary to consider about the acoustic feature in the cabin, and to design it. However, I hear that it is possible only to the frequency range of approximately 0-300Hz by the analysis using FEM. On the other hand, the frequency range of 300-1000Hz, called ‘middle frequency range’ is regarded as important about the design of the cabin, but the analytical technique of this range is nonestablishment. Therefore we perform a study to suggest the new analytical technique of this middle frequency range. In this study, we suggest the analytical technique of the acoustic absorption sound field using the mode distortion energy method as the first stage of analyzing a cabin. By this technique, we demand the energy of the air domain and the energy of the sound absorption material domain from the model that sound absorption material was added to on the wall of the cuboid space each and derive the same loss coefficient by the ratio of energy used by energy and sound absorption material of the whole space. At first we compare the truth level by the theory analysis with the solution of the same acoustic absorption sound field by the suggestion technique in simulation and confirm the validity of the suggestion technique. Then, we compare it with the experimental value in the model who stuck sound absorption material on the wall entire surface and the model that stuck sound absorption material on a part of the wall and confirm the validity of the suggestion technique experimentally. Finally we perform a comparison between suggestion technique and classic technique using A and show the thing that is more correct than classic technique.
Redox-Responsive Multicompartment Vesicles of Ferrocene-Containing Triblock Terpolymer Exhibiting On–Off Switchable Pores (2015)

Multicompartment vesicles of ferrocene-containing triblock terpolymer containing on-off switchable pores in the vesicular membrane are prepared by seeded RAFT polymerization. In these multicompartment vesicles, the incompatible solvophobic poly(4-vinylbenzyl ferrocenecarboxylate) (PVFC) and poly(benzyl methacrylate) (PBzMA) blocks form the porous phase-segregated membrane and the solvophilic poly[2-(dimethylamino) ethyl methacrylate] block locates at the inner and outer sides of the membrane. These porous multicompartment vesicles are redox-responsive and the membrane pores can be on-off switched through redox triggering. These porous multicompartment vesicles are deemed to be new nanoassembly of ABC triblock terpolymer and are anticipated to be a smart host to load and release guests.
Molecular biology of salt tolerance in the facultative halophyte Mesembryanthemum crystallinum: Identification and regulation of stress-responsive mRNAs. (1992)

As sessile organisms, plants are subject to numerous environmental insults. Of these, salinity is one of the most widespread and important in terms of limiting plant distribution and productivity. Molecular studies have established that plants challenged by high salinity respond by increasing expression of specific genes. A functional role for the products of such genes in stress tolerance has not been established, however, and little is known about the biochemical mechanisms that allow plants to tolerate osmotic stress. Mesembryanthemum crystallinum is a facultative halophyte capable of adjusting to and surviving in highly saline conditions. I have generated and screened a subtracted cDNA library to identify mRNAs that accumulate during this plant's adaptation to salt stress. Three mRNAs were identified that increased in abundance in leaf tissue of salt stressed plants. Patterns of induction for these mRNAs differed. The most dramatically-induced mRNA, Imt1, was characterized in depth. Imt1 expression was induced in leaves and, transiently, in roots. Nuclear run-on assays indicated that the gene is transcriptionally regulated. In several respects, the expression of Imt1 differed from that of other salinity-responsive genes involved in photosynthetic metabolism in M. crystallinum: The mRNA was induced by salinity and low temperature, but not by drought, and its induction by stress was not influenced by plant age. Imt1 encoded a predicted polypeptide of Mr 40,250 which exhibited sequence similarity to several hydroxymethyl transferases. The IMT1 protein was expressed in E. coli and identified by functional assay as a myo-inositol methyl transferase that catalyzes the first step in the biosynthesis of the cyclic sugar alcohol pinitol. The presence of high levels of sugar alcohols has been correlated with osmotolerance in a wide range of organisms, and the stress-initiated transcriptional induction of IMT1 expression in a facultative halophyte provides the strongest support to date for the importance of sugar alcohols in establishing tolerance to osmotic stress in higher plants. The ability of this methyl transferase to generate a putative osmoprotectant from a ubiquitous plant substrate makes it an attractive candidate enzyme for the creation of stress-resistant transgenic plants.
Full duplex cellular systems: will doubling interference prevent doubling capacity? (2015)

Recent advances in antenna and RF circuit design have greatly reduced the crosstalk between the transmitter and receiver circuits on a wireless device, which enable radios to transmit and receive on the same frequency at the same time. Such a full duplex radio has the potential to double the spectral efficiency of a point-to-point radio link. However, the application of such a radio in current cellular systems (3GPP LTE) has not been comprehensively analyzed. This article addresses the fundamental challenges in incorporating full duplex radios in a cellular network to unlock the full potential of full duplex communications. We observe that without carefully planning, full duplex transmission might cause much higher interference in both uplink and downlink, which greatly limits the potential gains. Another challenge is that standard scheduling methods which attempt to achieve the maximum capacity gain lead to a severe loss in energy efficiency. In this article, we identify new tradeoffs in designing full duplex enabled radio networks, and discuss favorable conditions to operate in full duplex mode. New scheduling algorithms and advanced interference cancellation techniques are discussed, which are essential to maximize the capacity gain and energy efficiency. Under this new design, most of the gain is achievable with full duplex enabled base stations, while user equipment still operates in half duplex mode.
Comparing Model Predictive Control and input shaping for improved response of low-impedance robots (2015)

With an increasing number of robots that can exhibit compliant behavior for safety in operating near humans (either through passive components or active control), additional methods for controlling these robots are needed. In particular, robot arms with low impedance can be safer for working in delicate environments if the effects of dealing with an underdamped robot system can be mitigated to improve performance. This paper focuses on comparing methods that allow a seven degree of freedom Series Elastic Actuator arm to operate with very low impedance while mitigating unwanted oscillation at the end effector. We show that by implementing feedback linearizion in conjunction with input shaping we can reduce residual oscillation for a seven degree of freedom robot arm. We also show that a Cartesian Model Predictive Controller (MPC) is able to significantly reduce residual oscillations while maintaining compliance. Comparing these two methods shows that for our tests for large displacements, MPC has a maximum overshoot of only 0.26% in the worst case where input shaping has at least 5.80% overshoot even in the best case. In addition, despite the fact that MPC is a feedback controller (unlike the open-loop input shaping method), it is still able to maintain compliance at the joints and end effector where we estimated MPC to exhibit a stiffness of 234 N/m as compared to the nominal low impedance controller with a stiffness of 262 N/m. Similar to input shaping (which is a command generation method), MPC is able to generate these commands without any slewing or path planning.

Safe automatic flight back and landing of aircraft flight reconfiguration function (FRF) (2008)

SOFIA (Safe Automatic Flight Back and Landing of Aircraft) project is a response to the challenge of developing concepts and techniques enabling the safe and automatic return to ground in the event of hostile actions. Activities in this sense have been started in the framework of the SAFEE SP3 (Secure Aircraft in the Future European Environment Sub-Project 3) project. SOFIA project is proposed as the continuation of the SAFEE works on FRF (Flight Reconfiguration Function), the system to automatically return the aircraft to ground. SOFIA will design architectures for integrating the FRF system into several typologies of avionics for civil transport aircraft; development of one of this architectures; validation, following E-OCVM (European Operational Concept Validation Methodology) of the FRF concept and the means to integrate it in the current ATM (Air Traffic Management); safety assessment of FRF at aircraft and operational (ATC-Air Traffic Control) levels. The SOFIA product is the FRF system that will take the control of the aircraft and will manage to safely return it to ground under a security emergency (e.g. hijacking), disabling the control and command of the aircraft from the cockpit. This means to create and execute a new flight plan towards a secure airport and landing the aircraft at it. The flight plan can be generated in ground (ATC), or in a military airplane and transmitted to the aircraft, or created autonomously at the FRF.
