Development of a Dual-Polarized Direction-Variable Liquid-Crystal Meta-Surface Reflector for Intelligent Reflecting Surface (2023)

Intelligent reflecting surfaces (IRSs) have been attracting attention as a solution to coverage hole problems in millimeter-wave communication areas. They are considered to be one of the key technologies of next-generation mobile communication systems. Since polarized multiple-input-multiple-output (MIMO) is utilized in millimeter-wave communication systems to deliver high-speed data transmission, an IRS is also required to be applied for polarized MIMO and reflect signals in a wide angle range. To realize an IRS for the polarized MIMO, the IRS is required to reflect the signal of each polarization in the same direction with high isolation. In addition, the IRS is required to control the reflection phase over a wide range. In recent research, many proposals related to the development of IRSs have been proposed. However, since the configuration of a conventional IRS with diodes controls the reflection characteristics by controlling the electric length or shape of the reflecting element, it becomes asymmetrical in the direction of each polarization and it is difficult to apply polarized MIMO. To solve this problem, in this paper, we propose a new design of a dual-polarized liquid-crystal-based IRS for 28 GHz mobile communication systems. Since the proposed IRS controls the reflecting phase by controlling the electric thickness of the substrate, the IRS can control the reflecting phase without changing the shape of the reflecting element. By optimizing the design of the reflecting element, the IRS can achieve a wide reflection phase control of 260 degrees for both vertical and horizontal polarizations. The IRS can also control the reflection direction of each polarization in the range of ±60 degrees with a high isolation of more than 20 dB. The main contributions of this paper are 1) a proposal for the design of a liquid crystal IRS for polarized MIMO; 2) a proposal of a design method for the liquid-crystal IRS using unit cell analysis; 3) verification of the proposed IRS through electromagnetic field analysis; 4) development of the proposed liquid-crystal IRS; 5) experimental verification of the proposed IRS in an anechoic chamber, and 6) derivation of the MIMO channel capacity of the proposed dual-polarized IRS.

Priming of CD4+ and CD8+ T cell responses using a HCV core ISCOMATRIX™ vaccine: A phase I study in healthy volunteers (2009)

The disease burden and public health impact of chronic HCV infection continues to be a major problem globally. Current treatment for chronic HCV infection is not effective in all patients and is frequently associated with unacceptable side effects. Clearly a need exists for improved treatments and one such strategy is the use of therapeutic vaccines. Although still not completely understood, emerging data indicate that the generation of CD4(+) and CD8(+) T cells are important for the clearance of HCV. We have developed a prototype vaccine with the HCV Core protein and ISCOMATRIX adjuvant (HCV Core ISCOMATRIX vaccine). ISCOMATRIX vaccines have been shown to induce CD4(+) and CD8(+) T cell responses to a range of antigens in both animal models and in human studies. Additionally, ISCOMATRIX vaccines have been shown to be safe and generally well tolerated in several clinical trials. Preliminary studies demonstrated that the prototype HCV Core ISCOMATRIX vaccine induced strong CD4(+) and CD8(+) T cell responses in monkeys following immunization. Here we show the results of a Phase I placebo controlled, dose escalation clinical study designed to evaluate the safety, tolerability and immunogenicity of the HCV Core ISCOMATRIX vaccine in healthy individuals. The 30 subjects received three immunizations of HCV Core ISCOMATRIX vaccines or placebo vaccine on days 0, 28 and 56. The HCV Core ISCOMATRIX vaccines contained 5, 20 or 50 microg HCV Core protein with 120 mug ISCOMATRIX adjuvant. The adverse events reported were generally mild to moderate in severity, of short duration and self-limiting. The most common adverse events were injection site reactions such as pain and redness as well as myalgia. Antibody responses were detected in all but one of the participants receiving the HCV Core ISCOMATRIX vaccine and there was no indication of a dose response. CD8(+) T cell responses were only detected in two of the eight participants receiving the highest dose. T cell cytokines were detected in 7 of the 8 participants in the highest dose group. The results of this study support the further evaluation of this prototype HCV Core ISCOMATRIX vaccine in HCV infected subjects.
Multiple byte processing with full-word instructions (1975)

A method is described which allows parallel processing of packed data items using only ordinary full-word computer instructions, even though the processing requires operations whose execution is contingent upon the value of a datum. It provides a useful technique for processing small data items such as alphanumeric characters.
Mechanical properties of self-welded silicon nanobridges (2005)

Mechanical properties of self-welded [111] single-crystal silicon nanowire bridges grown between two silicon posts using metal-catalyzed chemical vapor deposition were determined using both dynamic and static measurements. The static tests were carried out using atomic force microscopy (AFM) to measure the nanowires’ Young’s modulus and the strength of the self-welded junctions. The AFM-measured Young’s modulus ranged from 93 to 250 GPa (compared to 185 GPa for bulk silicon in the [111] direction) depending on the nanowire diameter, which ranged from 140 to 200 nm. The self-welded wire could withstand a maximum bending stress in the range of 210–830 MPa (larger than bulk silicon), which also depended on the nanowire diameter and loading conditions. The beam broke close to the loading point, rather than at the self-welded junction, indicating the excellent bond strength of the self-welded junction. The vibration spectra measured with a network analyzer and a dc magnetic field indicated a dynamic Young’s modulus of 140 GPa, in good agreement (within the experimental error) with the static measurement results.
New organolanthanide complexes containing a σ-bonded 1,3-dithiane. Crystal structures of [M(C5H4But)2(C4H7S2-1,3)]·LiCl·2thf (M = Lu or Y; thf = tetrahydrofuran) (1995)

New complexes of Y and Lu have been synthesized and fully characterized by single-crystal X-ray analysis: [M(C5H4But)2(C4H7S2-1,3)]·LiCl·2thf (M = Lu 1 or Y 2, thf = tetrahydrofuran). Both complexes crystallize from pentane at 0 °C. The crystal of 1 has space group P with a= 11.489(4), b= 14.438(6), c= 20.217(4)Å, α= 94.16(3), β= 89.76(2) and γ= 97.58(3)°. Least-square refinements based on 5881 reflections [l > 2.0σ(I)] converged to a final R= 0.072. Complex 2 crystallizes in orthorhombic unit cell and space group Pbca with a= 14.744(6), b= 21.148(7) and c= 21.472(6)Å. Least-squares refinement based on 1570 reflections [l > 2.0σ(I)] converged to a final R= 0.081. The complexes contain the anion of 1,3-dithiane included into a pentagonal co-ordination ring formed by M (Lu or Y), C, S, Li and Cl atoms. 1,3-Dithiane is σ bonded to the metal (Y or Lu) through the 2-carbon atom. Proton and 13C NMR spectra suggest high conformational stability of the 1,3-dithiane ring in solution at room temperature. The complexes react with protonic acids such as water, NH(SiMe3)2 and HCCPh releasing free 1,3-dithiane and forming corresponding cyclopentadienyl derivatives.

Intranasal anticonvulsive treatment in rural settings of developing countries (2006)

642 http://neurology.thelancet.com Vol 5 August 2006 bias due to diff ering epilepsy severity in earlier ABCB1 studies leaves the possibility that ABCB1 is contributory in a few patients with severe refractory epilepsy, although the evidence looks increasingly tenuous. Metaanalysis of all ABCB1 studies may provide resolution, but heterogeneity of patients will be a challenge. What lessons can we take home from the work of Leschziner and colleagues? First, they should be congratulated for showing that a prospective genetic-association study of epilepsy is feasible. The prospective design will ensure that, with time, we can look forward to the emergence of new data from the cohort, including late development of AED resistance. Second, researchers should consider doing a metaanalysis using a consensus defi nition of AED resistance. Finally, clinicians can take comfort in the fact that while researchers grapple with defi ning AED resistance, clinical predictors (panel) continue to provide guidance on caring for patients with epilepsy.

Optical properties and nonradiative decay of Sm2+in CaF2-YF3and CaF2-LaF3mixed crystals (1987)

The authors have obtained the absorption and emission spectra for the Sm2+ impurity in the mixed fluorides, Ca1-xYxF2+x and Ca1-xLaxF2+x. From these spectra they conclude that the Sm2+ ions tend to be coordinated by one or more extra F- ions in addition to the normal eightfold coordination expected in CaF2. Measurements of the emission lifetime and intensity as a function of temperature lead them to propose that the luminescence quenching of Sm2+ in the mixed fluorides is due to a competition between ionisation of the 4f55d level with relaxation into the 5D0 (4f6) emitting state. In addition, the thermal activation energy for Sm2+ emission quenching in various alkaline-earth halides is consistent with the calculated optical separation of the 4f55d level from the conduction band of the host, lending further support to the ionisation mechanism of emission quenching.
X-exome sequencing in Finnish families with Intellectual Disability - four novel mutations and two novel syndromic phenotypes (2014)

All of the mutations found in this study are being reported for the first time in Finnish families with several affected male patients whose etiological diagnoses have remained unknown to us, in some families, for more than 30 years. This study illustrates the impact of X-exome sequencing to identify rare gene mutations and the challenges of interpreting the results. Further functional studies are required to confirm the cause of the syndromic phenotypes associated with ZMYM3 and SYP in this study.
Association of epicardial adipose tissue with proteomics, coronary flow reserve, cardiac structure and function, and quality of life in heart failure with preserved ejection fraction: insights from the PROMIS‐HFpEF study (2022)

Increased EAT was associated with cardiac structural alterations and proteins expressing adiposity, inflammation, lower insulin sensitivity and endothelial dysfunction related to HFpEF pathology, probably driven by general obesity. Potential local mechanical or paracrine effects mediated by EAT remain to be elucidated.

A Pilot Study of Quantitative MRI Parametric Response Mapping of Bone Marrow Fat for Treatment Assessment in Myelofibrosis (2016)

Myelofibrosis (MF) is a hematologic neoplasm arising as a primary disease or secondary to other myeloproliferative neoplasms (MPNs). Both primary and secondary MF are uniquely associated with progressive bone marrow fibrosis, displacing normal hematopoietic cells from the marrow space and disrupting normal production of mature blood cells. Activation of the JAK2 signaling pathway in hematopoietic stem cells commonly causes MF, and ruxolitinib, a drug targeting this pathway, is the treatment of choice for many patients. However, current measures of disease status in MF do not necessarily predict response to treatment with ruxolitinib or other drugs in MF. Bone marrow biopsies are invasive and prone to sampling error, while measurements of spleen volume only indirectly reflect bone marrow status. Toward the goal of developing an imaging biomarker for treatment response in MF, we present preliminary results from a prospective clinical study evaluating parametric response mapping (PRM) of quantitative Dixon MRI bone marrow fat fraction maps in four MF patients treated with ruxolitinib. PRM allows for the voxel-wise identification of significant change in quantitative imaging readouts over time, in this case the bone marrow fat content. We identified heterogeneous response patterns of bone marrow fat among patients and within different bone marrow sites in the same patient. We also observed discordance between changes in bone marrow fat fraction and reductions in spleen volume, the standard imaging metric for treatment efficacy. This study provides initial support for PRM analysis of quantitative MRI of bone marrow fat to monitor response to therapy in MF, setting the stage for larger studies to further develop and validate this method as a complementary imaging biomarker for this disease.
Defense against pollution attacks in network coding (2012)

Network coding is a paradigm that advocates that intermediate nodes are allowed to combine, in addition to forward, packets. This idea has generated a significant amount of attention in the research community and has been shown to improve throughput and robustness. However, network coding is particularly vulnerable to pollution attacks, where corrupted packets injected by attackers may cause significant degradation of network performance. If network coding is to succeed, it has to overcome pollution attacks. As a result, there is a large body of work, in both the communications and applied cryptography communities, that proposes defense schemes for network coded systems against pollution attacks. 
In this thesis, we combat pollution attacks in both intra and inter-session coding, using cryptographic primitives. In particular, we present two efficient, comprehensive defense schemes for intra-session coding: one for directed acyclic networks that have fixed topologies and one for general networks that have dynamic topologies. Both of these schemes can provide in-network attack detection as well as precise identification of the location of attackers. They are built on a novel homomorphic message authentication code (MAC) scheme called SpaceMac. To the best of our knowledge, SpaceMac is the first homomorphic MAC scheme which allows for authenticating a subspace that expands over time. We implemented SpaceMac in both Java and C++ as a library and made the source code publicly available. 
In addition, we present an efficient in-network attack detection scheme for inter-session coding. The detection scheme is built on a novel multi-source homomorphic MAC scheme called InterMac. To the best of our knowledge, InterMac is the first homomorphic MAC scheme that allows tags to be generated under multiple, different keys. 
Finally, we propose a data auditing scheme called NC-Audit for network coding storage. NC-Audit is built on SpaceMac and on a novel chosen-plaintext-secure encryption scheme for network coding called NCrypt. NC-Audit exploits the similarity between pollution detection and data integrity checking to provide an efficient, privacy-preserving integrity checking, as well as support for efficient data repair and data dynamics.
Evaluation of Cross-Calibrated 68Ge/68Ga Phantoms for Assessing PET/CT Measurement Bias in Oncology Imaging for Single- and Multicenter Trials (2016)

Quantitative PET imaging is an important tool for clinical trials evaluating the response of cancers to investigational therapies. The standardized uptake value, used as a quantitative imaging biomarker, is dependent on multiple parameters that may contribute bias and variability. The use of long-lived, sealed PET calibration phantoms offers the advantages of known radioactivity activity concentration and simpler use than aqueous phantoms. We evaluated scanner and dose calibrator sources from two batches of commercially available kits, together at a single site and distributed across a local multicenter PET imaging network. We found that radioactivity concentration was uniform within the phantoms. Within the regions of interest drawn in the phantom images, coefficients of variation of voxel values were less than 2%. Across phantoms, coefficients of variation for mean signal were close to 1%. Biases of the standardized uptake value estimated with the kits varied by site and were seen to change in time by approximately ±5%. We conclude that these biases cannot be assumed constant over time. The kits provide a robust method to monitor PET scanner and dose calibrator biases, and resulting biases in standardized uptake values.
[A megatrial of ARB in Japan--CASE-J]. (2002)

Guidelines for antihypertensive therapy by World Health Organization/International Society of Hypertension(WHO/ISH) and the Joint National Committee(JNC) have been widely accepted by doctors in the world. In Japan, those for Japanese patients(JSH2000) were prepared last year by Japanese Society of Hypertension considering the difference in the drug metabolism, life style, frequencies of complications, etc. in the elderly. Although angiotensin II receptor antagonists are recommended as one of the first line treatment in JSH2000, no large-scale studies have been conducted in Japan. Therefore, CASE-J study has been designed in order to examine the efficacy of Candesartan Cilexetil, an angiotensin II receptor antagonist, comparing with that of amlodipine besilate, a calcium antagonist, in high-risk hypertensive patients using the incidence of cardiovascular events as an endpoint. The study was started in September 2001 and 4,000 patients will be recruited by December 2002. The results are expected to be presented at the meeting of International Hypertensive Society held in Fukuoka in 2006.
An Adaptive Fuzzy Controller for Constant Cutting Force in End-Milling Processes (2006)

A novel multi-level fuzzy control (MLFC) system is introduced and implemented for online force control of end-milling processes to increase machining productivity and improve workpiece quality, where the cutting force is maintained at its maximum allowable level in the presence of different variations inherent in milling processes, such as tool wear, workpiece geometry and material properties. In the controller design, the fuzzy rules are generated heuristically without any mathematical model of the milling processes. An adaptation mechanism is embedded in to tune the control parameters on-line and the resultant closed-loop system is guaranteed to be stable based on the input-output passivity analysis. In the experiment, the control algorithm is implemented using a National Instrument real-time control computer in an open architecture control environment, where high metal removal rates (MRR) are achieved and the cycle time is reduced by up to 34% over the case without any force controller, and by 22% compared with the regular fuzzy logic controller (FLC), thereby indicating its effectiveness in improving the productivity for actual machining processes.
Flexible Electronics: What can it do? What should it do? (2010)

The development of low temperature, thin film transistor processes that has enabled flexible displays also presents opportunities for flexible electronics. A variety of flexible digital and analog electronics have been demonstrated, although typically of modest performance. We review the state-of-the-art in flexible electronics followed by a discussion of the constraints, remaining challenges and realistic potential applications of thin film transistors and flexible integrated systems.
Dynamic fair node spectrum allocation for ad hoc networks using random matrices (2015)

Dynamic Spectrum Access (DSA) is widely seen as a solution to the problem of limited spectrum, because of its ability to adapt the operating frequency of a radio. Mobile Ad Hoc Networks (MANETs) can extend high-capacity mobile communications over large areas where fixed and tethered-mobile systems are not available. In one use case with high potential impact, cognitive radio employs spectrum sensing to facilitate the identification of allocated frequencies not currently accessed by their primary users. Primary users own the rights to radiate at a specific frequency and geographic location, while secondary users opportunistically attempt to radiate at a specific frequency when the primary user is not using it. We populate a spatial radio environment map (REM) database with known information that can be leveraged in an ad hoc network to facilitate fair path use of the DSA-discovered links. Utilization of high-resolution geospatial data layers in RF propagation analysis is directly applicable. Random matrix theory (RMT) is useful in simulating network layer usage in nodes by a Wishart adjacency matrix. We use the Dijkstra algorithm for discovering ad hoc network node connection patterns. We present a method for analysts to dynamically allocate node-node path and link resources using fair division. User allocation of limited resources as a function of time must be dynamic and based on system fairness policies. The context of fair means that first available request for an asset is not envied as long as it is not yet allocated or tasked in order to prevent cycling of the system. This solution may also save money by offering a Pareto efficient repeatable process. We use a water fill queue algorithm to include Shapley value marginal contributions for allocation.
