Low-Profile Strip-Loaded Textile Antenna With Enhanced Bandwidth and Isolation for Full-Duplex Wearable Applications (2020)

A novel dual-port textile antenna with a low profile and enhanced bandwidth is proposed for 2.45 GHz IMS-band full-duplex wearable applications. The antenna is developed on a textile material by using an advanced screen-printing technology and, thus, exhibits a very good structural flexibility and a high manufacturing accuracy. To improve the bandwidths at the two input ports, an innovative method is introduced for the first time where two additional strips are incorporated into the antenna design. These additional strips are placed perpendicularly to the feed lines to generate another resonant frequency, which is then combined with the fundamental mode of the patch antenna, producing the second-order resonant properties with enhanced bandwidths. The proposed strips are also beneficial to significantly improve the isolation between the two channels/ports. To maintain a robust linkage, a study of structural deformation is carried out by bending the antenna along both the 0° and 45° directions. The experimental results also show that the antenna is robust to the human tissue loading, where the specific absorption rate (SAR) is lower than 0.37 W/kg when the antenna is fully attached. The measured results agree reasonably well with the simulations providing experimental verification of the design concept. The antenna is believed to be the first dual-mode textile antenna of its type which features a low profile, improved bandwidth, high isolation, and low cost, making it a good candidate for potential full-duplex wearable applications.

Driving Characteristics of Micro Artificial Muscle using Electro-conjugate Fluid (2004)

Soft robot inspired from natural systems is one of keywords in the robotic field in last decade. Accordingly, there have been developed many types of artificial muscles including pneumatic ones, ion-exchange polymer composite ones, polymer gels, shape memory alloys, and so on. On the other hand, using the electro-conjugate fluid, which generates powerful jet flow with high voltage supply (〜 kV), we can construct a compact pressure source. In this study, authors propose a new type of micro artificial muscle (< 1 cm^3) utilizing electro-conjugate fluid. The essence of this study is to develop the micro artificial muscle integrated with micro pressure source, which enables us to construct an autonomous system and/or artificial muscle array.
On the Successful Delivery Probability of Full-Duplex-Enabled Mobile Edge Caching (2019)

Cache hit ratio (CHR) is a common metric to evaluate the performance of an edge caching system. While the CHR is efficient to measure throughput reduction gain, it fails to guarantee user quality of experience since the CHR does not capture the last-mile channel uncertainty. In this letter, we investigate a novel successful delivery probability (SDP) metric of full-duplex-enabled mobile edge caching (FD-MEC) systems, defined as a probability that the user receives the requested file before a tolerable delay. First, the average SDP is derived in a closed-form expression for arbitrary caching policy and network topology, taking into account the wireless fading distribution. Second, based on the derived SDP, a sub-optimal cache placement is proposed to maximize the average SDP, which is analytically shown to surpass both the most popular and uniform caching policies. Finally, the numerical results are presented to verify the accuracy of our analysis and demonstrate the effectiveness of our proposed cache placement design.

The Role of Fractures in Geological CO2 Storage in Saline Aquifers (2021)

Summary Natural or induced fractures are typically present in subsurface geological formations, which are of interest for geo-energy production and storage as well as for long-term carbon dioxide storage. Instinctively, fracture networks may undermine storage security as they are highly conductive pathways which may lead to the leakage of CO2. In addition, they may act as flow barriers, causing significant pressure and stress gradients. Nevertheless, despite their high sensitivities, impacts of fractures on the full-cycle storage process have not been fully understood. In this study, a numerical model is used to examine the role of a single fracture on the flow and transport of CO2 plume in various scenarios. A unified multiphysics framework is developed to model the essential trapping mechanisms in a robust manner. Important is that the projection-based embedded discrete fracture model is incorporated into the framework to describe fractures with varying conductivities. In particular, we focus on the dissolution trapping. Impacts of fracture location, fracture inclination angle, as well as fracture-matrix permeability ratio are systemically studied. Results indicate that the fracture exhibits differing effects regarding the dissolution trapping, and therefore, accurate characterization of fracture geometry and its conductivity is essential for evaluation of CO2 storage in fractured formations.

From sub-Terahertz to Terahertz: challenges and Design Considerations (2020)

NR Rel-15 physical layer specifications (released on December 2018) by 3GPP targeting IMT 2020 can support deployments in frequency ranges 410 MHz - 7.125 GHz and 24.25 GHz - 52.6 GHz. The support of higher frequency bands with large chunks of contiguous spectrum was deemed essential to fulfilling IMT 2020 vision of 20 Gbps peak data- rate in realistic deployment scenarios. It is also expected that global IMT traffic will grow 10 - 100 times from 2020 to 2030 and in order to support such growth Terahertz spectrum provides an attractive choice. In this paper, we describe the challenges in power amplifier, analog-to- digital design and impairments from phase noise that is expected in such regime. Considering such impairments, we show that realistic power amplifier backoff ratios are strongly correlated with the choice of a waveform. We provide results to show that phase noise could be mitigated by an appropriate choice of waveform and reference signals for compensation while a judicious choice of frame structure can be used to maintain reasonable scheduling and processing complexity. In order to maintain simultaneous connectivity to multiple base-stations resulting in large timing differences at the receiver, the isolation between panels at the user equipment can be successfully used.

Investigation of basic imaging properties in digital radiography. 5. Characteristic curves of II–TV digital systems (1986)

A simple method was devised to determine the characteristic curve of image intensifier (II)-TV digital imaging systems, which relates the output pixel value to the input relative x-ray intensity. To provide a wide range of x-ray intensities incident on the II, we used an aluminum stepwedge consisting of nine steps with thickness increments of 6.3 mm, together with an 0.81-mm-thick copper plate. The x-ray field was narrowly collimated to the area occupied by the stepwedge in order to reduce the effect of veiling glare. The relative x-ray intensities transmitted through each step of the stepwedge were determined by using screen-film systems. The gradient curve of the system was derived from the slope of the characteristic curve. Results obtained with a Siemens Digitron 2 system showed that its characteristic and gradient curves depended upon the matrix size used, but did not change with the II field size. The validity of the characteristic curve was demonstrated by measurement of iodine attenuation curves obtained with the II-TV digital system at different exposure levels.

Fabrication and optical behavior of graded-index, moth-eye antireflective structures in CdTe (2016)

A simple and scalable method, based on dip-coat colloidal lithography, mask reduction, and plasma-based pattern transfer, is presented to create graded-index, moth eye-inspired antireflective features on II–VI semiconductors. Hexagonal arrays of isolated conical frusta with tunable geometry (top diameter = 200–1300 nm, pitch = 310–2530 nm, and height = 790–7100 nm) were realized by isotropic etching of various size silica colloid masks before pattern transfer into the underlying substrate. Substantial increases in single-side direct and total infrared (IR) transmission across the 4–20 μm range (9%–15% for CdTe thin films and 18% for bulk CdTe) were achieved, in excellent agreement with transfer matrix calculations and finite difference time domain optical simulations. The fabrication method presented can be used to enhance efficiency in multiple IR application areas including photovoltaics, optical system components, detectors, and focal plane array imagers.

Pulse delay measurement of the zero waveguide of material dispersion in optical fibres (1978)

Pulse delay measurements on fibres are reported over a wide wavelength range straddling the zero of material dispersion. Results for phosphosilicate and a range of germania-doped fibres indicate that the wavelength of negligible material dispersion lies in the range 1270-1350nm. The optimum wavelength depends on the concentration for fibres containing germania.
Optimization of 3D Plasmonic Crystal Structures for Refractive Index Sensing (2009)

We study the refractive index sensitive transmission of a 3D plasmonic crystal that consists of a square array of subwavelength cylindrical nanowells in a polymer conformally coated with a gold film. Using extensive 3D finite-difference time-domain simulations, we investigate the effect of system parameters such as periodicity, well diameter and depth, and metal thickness on its refractive index sensitivity. These theoretical results are also confirmed experimentally in some cases. Our calculations predict an enhancement in sensitivity by an order of magnitude when the plasmonic crystal characteristics are optimized.
Improvement of highly sensitive lidar with a thumb-sized sensor-head built using an optical fiber preamplifier (2012)

We have developed a LIDAR system with a sensor head which, although it includes a scanning mechanism, is less than 20 cc in size. The system is not only small, but is also highly sensitive. Our LIDAR system is based on time-of-flight measurements, and incorporates an optical fiber. The main feature of our system is the utilization of optical amplifiers for both the transmitter and the receiver, and the optical amplifiers enable us to exceed the detection limit set by thermal noise. In conventional LIDAR systems the detection limit is determined by the thermal noise, because the avalanche photo-diodes (APD) and trans-impedance amplifiers (TIA) that they use detect the received signals directly. In the case of our LIDAR system, the received signal is amplified by an optical fiber amplifier before reaching the photo diode and the TIA. Therefore, our LIDAR system boosts the signal level before the weak incoming signal is depleted by thermal noise. There are conditions under which the noise figure for the combination of an optical fiber amplifier and a photo diode is superior to the noise figure for an avalanche photo diode. We optimized the gains of the optical fiber amplifier and the TIA in our LIDAR system such that it would be capable of detecting a single photon. As a result, the detection limit of our system is determined by shot noise. We have previously demonstrated optical pre-amplified LIDAR with a perfect co-axial optical system[1]. For this we used a variable optical attenuator to remove internal reflection from the transmission and receiving lenses. However, the optical attenuator had an insertion loss of 6dB which reduced the sensitivity of the LIDAR. We re-designed the optical system such that it was semi-co-axial and removed the variable optical attenuator. As a result, we succeeded in scanning up to a range of 80 m. This small and highly sensitive measurement technology shows great potential for use in LIDAR.
Large-Scale Exome Sequencing Study Implicates Both Developmental and Functional Changes in the Neurobiology of Autism (2020)

We present the largest exome sequencing study of autism spectrum disorder (ASD) to date (n = 35,584 total samples, 11,986 with ASD). Using an enhanced analytical framework to integrate de novo and case-control rare variation, we identify 102 risk genes at a false discovery rate of 0.1 or less. Of these genes, 49 show higher frequencies of disruptive de novo variants in individuals ascertained to have severe neurodevelopmental delay, whereas 53 show higher frequencies in individuals ascertained to have ASD; comparing ASD cases with mutations in these groups reveals phenotypic differences. Expressed early in brain development, most risk genes have roles in regulation of gene expression or neuronal communication (i.e., mutations effect neurodevelopmental and neurophysiological changes), and 13 fall within loci recurrently hit by copy number variants. In cells from the human cortex, expression of risk genes is enriched in excitatory and inhibitory neuronal lineages, consistent with multiple paths to an excitatory-inhibitory imbalance underlying ASD.
Maximum Bayes Smatch Ensemble Distillation for AMR Parsing (2021)

AMR parsing has experienced an unprecendented increase in performance in the last three years, due to a mixture of effects including architecture improvements and transfer learning. Self-learning techniques have also played a role in pushing performance forward. However, for most recent high performant parsers, the effect of self-learning and silver data augmentation seems to be fading. In this paper we propose to overcome this diminishing returns of silver data by combining Smatch-based ensembling techniques with ensemble distillation. In an extensive experimental setup, we push single model English parser performance to a new state-of-the-art, 85.9 (AMR2.0) and 84.3 (AMR3.0), and return to substantial gains from silver data augmentation. We also attain a new state-of-the-art for cross-lingual AMR parsing for Chinese, German, Italian and Spanish. Finally we explore the impact of the proposed technique on domain adaptation, and show that it can produce gains rivaling those of human annotated data for QALD-9 and achieve a new state-of-the-art for BioAMR.
Engineering the Coupling Between the Berreman Mode and Nanobar Antennas in Epsilon-near-zero Materials (2018)

Timing Models for MOS Circuits (1983)

Performance is an important aspect of integrated circuit design, and depends in part on the speed of the underlying circuits. This thesis presents a new method of analyzing MOS circuit delay, based on a single-time-constant approximation. The timing models characterize the circuit by a single parameter, which depends on the resistance and capacitance of the circuit elements. To ensure the single- time-constant approximation is valid for a particular circuit, the timing models provide both an estimate and bounds for the output waveform. For circuits where the bounds are poor, an improved timing model is derived. These simple models provide insight about circuit performance issues, as well as determining the circuit delay. The timing models are first developed for linear networks and then are extended to model MOS circuits driven by a step input. By using the single-time-constant approximation, the output waveform of a complex MOS circuit can be modelled by the output of a circuit consisting of a single MOS transistor and a single capacitor. Finally, a new circuit model of a gate is used to derive the output waveform of a circuit driven by an arbitrary input. The resulting timing model does not depend strongly on the shape of the input: the output waveform only depends on the input''s slope at the gate''s switching voltage.

<50% (4). This is particularly troubling considering the fact
that preclinical research over the last couple of years led to

Anti-CD44 Monoclonal Antibody Inhibits Heart Transplant Rejection Mediated by Alloantigen-primed CD4+Memory T Cells in Nude Mice (2010)

Donor-reactive CD4(+)memory T cells threaten the survival of transplanted organs. In this study, we used anti-CD44 monoclonal antibody (mAb) to inhibit adoptively transferred B6-reactive CD4(+)memory T cells (BALB/c origin) and to induce tolerance of B6 hearts in nude mice. The median survival time (MST) of the grafts was 6 days in the isotype group, and more than 100 days in the group treated with 8 doses of anti-CD44 at four-day intervals. Histological analysis revealed that the mean rejection level was Grade 3 in the isotype group, and Grade 0 or 1 in the multi-dose anti-CD44 treatment group. Compared with the isotype group, the multiply treated anti-CD44 group had significantly decreased IL-2 and IFN-γ expressions, while IL-10 and TGF-β were increased in the serum and the graft. Foxp3 in the graft was also increased. These data demonstrate that alloreactive CD4(+) memory T cells mediate the destruction of allografts, and the adhesion molecule CD44 plays an important role in this course. Anti-CD44 mAb may promote the reduction of CD4(+)memory T cells and the production of regulatory T cells (Tregs). Furthermore, Tregs are maintained at a certain level while suppressing cellular immunity and inducing the grafts long-term survival in transplant recipients.
Effect of Cation Substitution on the Oxygen Semipermeability of Perovskite-type Oxides (1988)

Abstract Oxygen semipermeability of LnCoO3-based perovskite-type oxides changed drastically by the partial substitution of A site and B site cations, Ba and Cu being the most effective substituents, respectively. Host rare earth cations (Ln) also affected the oxygen semipermeability, which increased with a decrease in ionic radius of Ln.
