A Study on Control Method to Reduce Collisions and Interferences between Multiple RFID Readers and RFID Tag (2009)

In relation to the method of controlling multiple RFID reader where multiple RFID readers recognize the RFID tag to reduce collisions and interferences of frequency between RFID readers, the multiple RFID reader control method proposed in this study is composed of Step 1 which configures a fixed number of RFID readers as multiple number of groups, Step 2 which selects an RFID reader among all readers in all groups as master reader and other readers as slaves, Step 3 in which master reader sends frequency hopping signal to master reader and slave readers, and Step 4 which performs frequency hopping with identical frequency for each group and with different frequencies among groups. Step 5 in which master and slave readers transmit tag signal to each RFID tag to recognize the tags follows after Step 4, and these steps are repeated to recognize all RFID tags.
8–13 μm InAsSb heterojunction photodiode operating at near room temperature (1995)

p +-InSb/π-InAs1−xSbx/n+-InSb heterojunction photodiodes operating at near room temperature in the 8–13 μm region of infrared (IR) spectrum are reported. A room-temperature photovoltaic response of up to 13 μm has been observed at 300 K with an x≊0.85 sample. The voltage responsivity-area product of 3×10−5 V cm2/W has been obtained at 300 K for the λ=10.6 μm optimized device. This was close to the theoretical limit set by the Auger mechanism, with a detectivity at room temperature of ≊1.5×108 cm Hz1/2/W.

Surface enhanced Raman spectroscopy (SERS) for <i>in vitro</i> diagnostic testing at the point of care (2017)

Abstract Point‐of‐care (POC) device development is a growing field that aims to develop low‐cost, rapid, sensitive in‐vitro diagnostic testing platforms that are portable, self‐contained, and can be used anywhere – from modern clinics to remote and low resource areas. In this review, surface enhanced Raman spectroscopy (SERS) is discussed as a solution to facilitating the translation of bioanalytical sensing to the POC. The potential for SERS to meet the widely accepted “ASSURED” (Affordable, Sensitive, Specific, User‐friendly, Rapid, Equipment‐free, and Deliverable) criterion provided by the World Health Organization is discussed based on recent advances in SERS in vitro assay development. As SERS provides attractive characteristics for multiplexed sensing at low concentration limits with a high degree of specificity, it holds great promise for enhancing current efforts in rapid diagnostic testing. In outlining the progression of SERS techniques over the past years combined with recent developments in smart nanomaterials, high‐throughput microfluidics, and low‐cost paper diagnostics, an extensive number of new possibilities show potential for translating SERS biosensors to the POC.
The Folding of Triangulated Cylinders, Part III: Experiments (1996)

This paper describes an experimental investigation of a type of foldable cylindrical structure, first presented in two earlier papers. Three cylinders of this type were designed and manufactured, and were then tested to find the force required to fold them. The results from these tests show some discrepancies with an earlier computational simulation, which was based on a pin-jointed truss model of the cylinders. Possible explanations for these discrepancies are explored, and are then verified by new simulations using computational models that include the effect of hinge stiffness, and the effect of geometric imperfections.
Reducing Feedback Overhead in Opportunistic Scheduling of Wireless Networks Exploiting Overhearing (2012)

We propose a scheme to reduce the overhead associated with channel state information (CSI) feedback required for opportunistic scheduling in wireless access networks. We study the case where CSI is partially overheard by mobiles and thus one can suppress transmitting CSI reports for time varying channels of inferior quality. We model the mechanism of feedback suppression as a Bayesian network, and show that the problem of minimizing the average feedback overhead is NP-hard. To deal with hardness of the problem we identify a class of feedback suppression structures which allow efficient computation of the cost. Leveraging such structures we propose an algorithm which not only captures the essence of seemingly complex overhearing relations among mobiles, but also provides a simple estimate of the cost incurred by a suppression structure. Simulation results are provided to demonstrate the improvements offered by the proposed scheme, e.g., a savings of 63-83% depending on the network size.
PHASE TRANSITIONS OF POLY(VINYLIDENE FLUORIDE) UNDER ELECTRIC FIELDS (2006)

ABSTRACT The electric poling behavior of poly(vinylidene fluoride) (PVDF) films was investigated by Fourier transition infrared spectrum (FT-IR), ferroelectric and piezoelectric effect test in this paper. PVDF undergoes a structural evolution under electric fields over a wide range of electric fields from 0 to 180 MV/m. The phase transitions were characterized as α phase to β phase via middle δ phase with increase of poled electric field intensity. According to ferroelectric hysteresis performance of PVDF films, it could be found that the trend of piezoelectric coefficient d33 which increased with poled electric field intensity was coincident with Boltzmann distributing function. And the results indicated that the range of the poled electric field intensity which brought the maximal remnant polarization was 100–125 MV/m, the maximal piezoelectric coefficient d33 for β phase of PVDF films was achieved 28 pC/N.
Pore architecture affects photocatalytic activity of periodic mesoporous nanocrystalline anatase thin films (2006)

We report the photocatalytic activity of periodic mesoporous nanocrystalline anatase thin films (denoted meso-nc-TiO2) using Methylene Blue (denoted MB) as a probe of pore architecture effects on reactivity. Specifically, 2D hexagonal and 3D cubic mesoporous nanocrystalline anatase thin films (denoted h-meso-nc-TiO2 and c-meso-nc-TiO2 respectively) annealed at different temperatures were investigated to reveal the effects of different pore architectures on the photocatalytic activity. The adsorption behavior of MB on the films annealed at the same temperature signaled that c-meso-nc-TiO2 has a larger accessible surface area but a lower adsorption surface affinity, compared to h-meso-nc-TiO2. In the case of the solid-state photodegradation of MB, the most efficacious photocatalyst was found to be c-meso-nc-TiO2 annealed at 450 °C. For MB in solution, a 400 °C annealed c-meso-nc-TiO2 was established to have the optimum photocatalytic activity among the samples investigated. The observed superior photocatalytic activity of c-meso-nc-TiO2 relative to both h-meso-nc-TiO2 and nc-TiO2 is believed to originate from the higher photoactivity of anatase nanocrystallites comprising the more open cubic framework. as well as geometrical advantages, such as a larger surface area and less obstructed 3D diffusion paths of guest molecules. It is concluded that the photocatalytic efficiency of periodic mesoporous nanocrystalline anatase thin films depends on the pore architecture.
Multi-stage generation of extreme ultraviolet dispersive waves by tapering gas-filled hollow-core anti-resonant fibers (2018)

In this work, we numerically investigate an experimentally feasible design of a tapered Ne-filled hollow-core anti-resonant fiber and we report multi-stage generation of dispersive waves (DWs) in the range 90-120 nm, well into the extreme ultraviolet (UV) region. The simulations assume a 800 nm pump pulse with 30 fs 10 µJ pulse energy, launched into a 9 bar Ne-filled fiber with a 34 µm initial core diameter that is then tapered to a 10 µm core diameter. The simulations were performed using a new model that provides a realistic description of both loss and dispersion of the resonant and anti-resonant spectral bands of the fiber, and also importantly includes the material loss of silica in the UV. We show that by first generating solitons that emit DWs in the far-UV region in the pre-taper section, optimization of the following taper structure can allow re-collision with the solitons and further up-conversion of the far-UV DWs to the extreme-UV with energies up to 190 nJ in the 90-120 nm range. This process provides a new way to generate light in the extreme-UV spectral range using relatively low gas pressure.
A Low-Complexity Real-Time 3-D Sonar Imaging System With a Cross Array (2015)

The development of real-time 3-D underwater imaging is restricted by the huge hardware cost and the computational burden associated with a large number of transducers. In this paper, a low-complexity real-time 3-D sonar imaging system with a cross array is proposed. The low complexity, in both hardware cost and computational load, is achieved by an innovative method of signal processing in the far field and the advantages of the cross array in minimal transducer numbers. The method consists of two parts: a multifrequency (MF) algorithm for the transmitting process and a parallel subarray (PS) algorithm for the receiving beamforming. The MF algorithm solves the real-time problem of the cross array by reducing the scanning time that is proportional to the number of transmissions. The PS algorithm improves the computational efficiency using a two-stage parallel and pipeline framework. The PS algorithm is an approximate method, and its precision is analyzed in this paper. The computational efficiency of the proposed method is compared with the direct method (DM) beamforming in both cross and planar arrays. A prototype, based on the innovative method, was designed and tested in pool and lake trials. The results demonstrate that the low-complexity system can satisfy the real-time requirement of 3-D underwater imaging applications with an acceptable imaging quality.
Mutations in the Fas Antigen in Patients With Multiple Myeloma (1997)

Abstract Programmed cell death, or apoptosis, is well documented as a physiological means of eliminating activated lymphocytes and maintaining immune homeostasis. Apoptosis has also been implicated in the targeting of tumor cells by cytotoxic T lymphocytes and natural killer cells. One of the two primary mechanisms used in cell-mediated cytotoxicity is the Fas/FasLigand system. Activated or transformed cells expressing the Fas antigen on their surface are susceptible to killing by immune effector cells that express the Fas ligand. Many neoplastic cells, including those derived from patients with multiple myeloma, express Fas antigen on their surface, but do not undergo apoptosis in response to antigen crosslinking. One possibility for the lack of Fas-mediated apoptosis includes mutations in the Fas antigen. Loss of function mutations in the Fas antigen have been associated with congenital autoimmune disease in humans, and have been defined as the genetic defect the in lpr mice. Mutations in the Fas antigen have not been previously described in cancer patients. In this study, we show that mutations occur in the Fas antigen which may cause loss of function and contribute to the pathogenesis of the neoplastic disease, multiple myeloma. Using reverse transcriptase-polymerase chain reaction (RT-PCR), single-stranded conformation polymorphism (SSCP) analysis, and DNA sequencing, we examined the cDNA structure of the Fas antigen in 54 bone marrow (BM) specimens obtained from myeloma patients. Six patient specimens (11%) did not express detectable levels of Fas antigen mRNA. Of the 48 BM specimens which did express Fas antigen, 5 (10%) displayed point mutations. All of the mutations identified were located in the cytoplasmic region of the Fas antigen known to be involved in transduction of an apoptotic signal. Two separate individuals demonstrated an identical mutation at a site previously shown to be mutated in the congenital autoimmune syndrome, ALPS. One patient exhibited a point mutation at a site only two amino acids removed from the documented lesion of the lprcg mouse. Although the functional status of these point mutations remains to be determined, we propose that Fas antigen mutations may contribute to the pathogenesis and progression of myeloma in some patients.
종설 : 식품 첨가물과 천식 (2006)

Purpose : To review the role of food additives in asthma and provide a practical approach for evaluation, diagnosis, and management of additive-induced asthma. Methods : Information was gathered from original articles, selected reviews and abstracts published in peer-reviewed journals and from selected textbook chapters, supplemented by the clinical experience of the authors. Results : In some patients, food additive ingestion can induce bronchospasm or exacerbation of symptoms in patients with chronic asthma. The most implicated agents are sulfites, followed by tartrazine, monosodium glutamate and others. However, geographic variations exist depending on the dietary habits. Conclusion : Food additives are worth considering as possible causes of bronchospasm or worsening of asthma. The medical history may be suggestive, particularly when symptoms occur to commercially prepared foods or to multiple unrelated foods. Physicians should also think of food additives in patients whose asthma is poorly controlled in spite of appropriate routine allergy evaluation, environmental control, and optimal pharmacologic therapy. Except for a few natural additives, allergy skin test and in-vitro tests are unreliable. A titrated oral challenge testing, preferably in a blind fashion would be the definitive diagnostic procedure.

Accurate Simulation Testbench for Nuclear Imaging Systems (2008)

Current testbenches for nuclear imaging devices aim to simulate only a single stage of the system at a time. This approach is useful in early design stages where accuracy is not necessary. However, it would be desirable that different tools could be combined to achieve more detailed simulations. In this work, a high precision testbench is presented. It has been developed to test nuclear imaging systems. Its accuracy lies in the possibility of linking different simulation tools using the right one for each part of the system. High energy events are simulated using Geant4 (High Energy Simulator). Analog and digital electronics are verified using SpectreVerilog or UltrasimVerilog (Cadence Design Syst. Inc., San Jose, CA, USA) and ModelSim (Mentor Graphics Corp, Wilsonville, OR, USA). This testbench structure can be used to test any physical topology, scintillation crystals, Photomultiplier Tubes (PMTs), Avalanche Photodiodes (APDs), with any kind of ASIC, discrete analog and digital electronics, thus reducing the prototyping and design time. New system developments can be easily verified using behavioral and circuital description models for analog and digital electronics. Finally, a dual-head continuous LSO scintillation crystal Positron Emission Tomography (PET) system has been used as an example for evaluation of the testbench.
Structural and optical properties of Pr doped BiFeO[sub 3] multiferroic ceramics (2013)

Pure and Pr substituted BiFeO3 (BFO) ceramics were synthesized by solid state reaction method. X-ray analysis shows the formation of BFO rhombohedral phase with R3c space group. Photoluminescent spectra of pure BFO showed blue emission corresponding to band gap at 2.67 eV. In Pr doped samples in addition to blue emission (2.67eV), a broad weak yellow emission has also been observed due to electronic transitions of dopant Pr3+ states. FTIR spectra showed two broad absorption peaks due to overlapping of Fe-O and Bi-O groups in the region 700 - 400 cm−1. These interesting optical properties of Pr doped BFO samples in visible region may find potential applications in optoelectronic devices.

Comparing Mobile Privacy Protection through Cross-Platform Applications (2013)

With the rapid growth of the mobile market, security of mobile platforms is receiving increasing attention from both research community as well as the public. In this paper, we make the first attempt to establish a baseline for security comparison between the two most popular mobile platforms. We investigate applications that run on both Android and iOS and examine the difference in the usage of their security sensitive APIs (SS-APIs). Our analysis over 2,600 applications shows that iOS applications consistently access more SS-APIs than their counterparts on Android. The additional privileges gained on iOS are often associated with accessing private resources such as device ID, camera, and users’ contacts. A possible explanation for this difference in SS-API usage is that privileges obtained by an application on the current iOS platform are invisible to end users. Our analysis shows that: 1) third-party libraries (specifically advertising and analytic libraries) on iOS invoke more SS-APIs than those on Android; 2) Android application developers avoid requesting unnecessary privileges which will be shown in the permission list during application installation. Considering the fact that an Android application may gain additional privileges with privilege-escalation attacks and iOS provides a more restricted privilege set accessible by third-party applications, our results do not necessarily imply that Android provides better privacy protection than iOS. However, our evidence suggests that Apple’s application vetting process may not be as effective as Android’s privilege notification mechanism, particularly in protecting sensitive resources from third-party applications.
Response to <i>Neisseria gonorrhoeae</i> by Cervicovaginal Epithelial Cells Occurs in the Absence of Toll-Like Receptor 4-Mediated Signaling (2002)

Toll-like receptors (TLRs) have recently been identified as fundamental components of the innate immune response to bacterial pathogens. We investigated the role of TLR signaling in immune defense of the mucosal epithelial cells of the lower female genital tract. This site provides first line defense against microbial pathogens while remaining tolerant to a complex biosystem of resident microbiota. Epithelial cells derived from normal human vagina, ectocervix, and endocervix expressed mRNA for TLR1, -2, -3, -5, and -6. However, they failed to express TLR4 as well as MD2, two essential components of the receptor complex for LPS in phagocytes and endothelial cells. Consistent with this, endocervical epithelial cells were unresponsive to protein-free preparations of lipooligosaccharide from Neisseria gonorrhoeae and LPS from Escherichia coli. However, they were capable of responding to whole Gram-negative bacteria and bacterial lysates, as demonstrated by NF-kappaB activation and proinflammatory cytokine production. The presence of soluble CD14, a high-affinity receptor for LPS and other bacterial ligands, enhanced the sensitivity of genital tract epithelial cells to both low and high concentrations of bacteria, suggesting that soluble CD14 can act as a coreceptor for non-TLR4 ligands. These data demonstrate that the response to N. gonorrhoeae and other Gram-negative bacteria at the mucosal surface of the female genital tract occurs in the absence of endotoxin recognition and TLR4-mediated signaling.
Vertebral Cancellous Bone Augmented with Stiffness-adapted PMMA Cement does not Show Acute Failure under Dynamic Loading (2015)

INTRODUCTION: An increased fracture risk has been reported for the adjacent vertebral bodies after vertebroplasty, which may be due to the high stiffness of PMMA. Using stiffness-adapted porous PMMA might reduce this risk. But the reduced failure strength of the porous cement could deteriorate under dynamic loading. The task of this study was to determine stiffness, acute failure, height loss and subsidence of cancellous bone augmented with porous PMMA under dynamic loading.
