Channel Selectivity of Satellite Transponders with the Antenna Combined with a Size-Reduced Metallic Waveguide Bandpass Filter Having Thin Metamaterial Resonators (2023)

Global and intercontinental networking relies on satellite communication. Its wireless communication system always has antennas and their feed assembly comprising waveguides. This makes the satellite payload heavy and costly. In this paper, a novel method is proposed to effectively reduce the size of a waveguide bandpass filter (BPF). Because the metallic cavities make the conventional waveguide end up with a large geometry, especially for high-order BPFs, very compact waveguide-type resonators having metamaterial zeroth-order resonance (WG-ZOR) are designed on the cross-section of the waveguide and substituted for the cavities. While the cavities are half-wavelength resonators, the WG-ZOR is shorter than one eighth of a wavelength. A substantial reduction in size and weight of the waveguide filter is observed as the resonators are cascaded in series through coupling elements in the X-band much longer than K- or Ka-band. An X-band of 7.25~7.75 GHz is chosen to verify the method as the passband with attenuation of 40 dB at 7.00 GHz and 8.00 GHz as the roll-off in the stopband. The BPF is manufactured using the CNC milling technique. The design is carried out with geometrical parameters, not of the level of 10 μm, but the level of 100 μm, which is good for manufacturers but a big challenge for component designers. The measurement of the manufactured metal waveguide filter reveals that the passband has about ≤1 dB and ≤-15 dB as insertion loss and reflection coefficient and the stopband has ≤-40 dB as attenuation, which are in good agreement with the results of the circuit and simulation. The proposed filter has a length of 3.5 λg as the eighth-order BPF, but the conventional waveguide is 5 λg as the seventh-order BPF for the same area of the cross-section. This metamaterial BPF is combined with a horn antenna. The filter enables the wide-band antenna to distinguish the band of transmission from that of noise suppression. This channel selectivity is obviously observed by the filter integrated antenna test.
Resource allocation scheme for reliability improvement in wireless USB networks (2013)

Wireless USB (WUSB) is the USB technology merged with WiMedia PHY /MAC based on success of wired USB, and it can be applied to various mobile applications such as laptop, cellular phone, etc. However the current WUSB protocol can't recover the link breakage occurred between WUSB host and device. This problem causes the critical problems in QoS provisioning to isochronous streams and mobile applications. Therefore, we propose a new resource allocation scheme for reliability improvement in Wireless USB networks.

Abstract IA4: Outcome prediction from the pattern of aberrations in prostate cancer genomes (2012)

Abstract One of the greatest challenges in prostate cancer care is distinguishing men with high-risk disease requiring aggressive therapy from those who can be managed with active surveillance. Therefore, we are pursuing an ongoing integrative genomic analysis of human primary and metastatic prostate cancers. We explore the clinical importance and pathogenicity of genomic lesions and their association with canonical features of prostate cancer biology. Previously, we found that global patterns of DNA copy number alterations (CNAs) in primary tumors were associated with disease recurrence after radical prostatectomy. Here, we will discuss our efforts to extend this discovery by validating the clinical importance of CNAs and structural rearrangements in independent cohorts, at multiple scales, and with orthogonal methods. Our principal goal is to deliver a clinical diagnosis informed by genomic abnormalities that impacts definitive treatment decisions in men diagnosed with prostate cancer. Citation Format: Barry S.

Thermoelectric signatures of the electron-phonon fluid in PtSn4 (2018)

In most materials, transport can be described by the motion of distinct species of quasiparticles, such as electrons and phonons. Strong interactions between quasiparticles, however, can lead to collective behaviour, including the possibility of viscous hydrodynamic flow. In the case of electrons and phonons, an electron-phonon fluid is expected to exhibit strong phonon-drag transport signatures and an anomalously low thermal conductivity. The Dirac semi-metal PtSn4 has a very low resistivity at low temperatures and shows a pronounced phonon drag peak in the low temperature thermopower; it is therefore an excellent candidate for hosting a hydrodynamic electron-phonon fluid. Here we report measurements of the temperature and magnetic field dependence of the longitudinal and Hall electrical resistivities, the thermopower and the thermal conductivity of PtSn4. We confirm a phonon drag peak in the thermopower near 14 K and observe a concurrent breakdown of the Lorenz ratio below the Sommerfeld value. Both of these facts are expected for an electron-phonon fluid with a quasi-conserved total momentum. A hierarchy between momentum-conserving and momentum-relaxing scattering timescales is corroborated through measurements of the magnetic field dependence of the electrical and Hall resistivity and of the thermal conductivity. These results show that PtSn4 exhibits key features of hydrodynamic transport.
An Integral Boundary Layer Method using Discontinuous Galerkin Discretization and Captured Transition Modeling (2020)

Viscous analysis is crucial for understanding aerodynamic performance metrics such as proﬁle drag. For three-dimensional (3D) viscous analysis, Reynolds-averaged Navier-Stokes (RANS) solvers are often the fastest available tool in practice but the required computational eﬀorts preclude its extensive use for preliminary design. In contrast, the integral boundary layer (IBL) method oﬀers a computationally more eﬃcient alternative with comparable eﬀectiveness when applicable. However, existing IBL methods mostly rely on two-dimensional (2D) or quasi-2D assumptions and thus remain to be extended to a fully 3D formulation for general conﬁgurations. To this end, we continue the development of an IBL method with discontinuous Galerkin (DG) ﬁnite element discretization and strong viscous-inviscid coupling. The current work proposes a captured laminar-to-turbulent ﬂow transition treatment for the IBL method that can be more conveniently extended to the 3D case compared to a previously examined ﬁtted transition approach. The current captured transition treatment also leverages a more robust nonlinear solution method and achieves accurate solution of transitional ﬂows. Moreover, correction to the standard DG discretization is introduced for well-behaved numerical solution. Numerical results of the proposed method in a 2D implementation compares well with XFOIL and demonstrate its capability for practical aerodynamic analysis with free transition.
GAZE-2 (2002)

GAZE-2 is an attentive video conferencing system that conveys whom users are talking to by measuring whom a user looks at and then rotating his video image towards that person in a 3D meeting room. Attentive Videotunnels ensure a parallax-free image by automatically broadcasting the feed from the camera closest to where the user looks. The system allows attentive compression by reducing resolution of video and audio feeds from users that are not being looked at.

Leukotoxin Confers Beta-Hemolytic Activity to Actinobacillus actinomycetemcomitans (2006)

Actinobacillus actinomycetemcomitans is the etiologic agent of localized aggressive periodontitis, a rapidly progressing oral disease that occurs in adolescents. A. actinomycetemcomitans can also cause systemic disease, including infective endocarditis. In early work on A. actinomycetemcomitans workers concluded that this bacterium is not beta-hemolytic. More recent reports have suggested that A. actinomycetemcomitans does have the potential to be beta-hemolytic. While growing A. actinomycetemcomitans on several types of growth media, we noticed a beta-hemolytic reaction on media from one manufacturer. Beta-hemolysis occurred on Columbia agar from Accumedia with either sheep or horse blood, but not on similar media from other manufacturers. A surprising result was that mutants of A. actinomycetemcomitans defective for production of leukotoxin, a toxin that is reportedly highly specific for only human and primate white blood cells, are not beta-hemolytic. Purified leukotoxin was able to lyse sheep and human erythrocytes in vitro. This work showed that in contrast to the accepted view, A. actinomycetemcomitans leukotoxin can indeed destroy erythrocytes and that the production of this toxin results in beta-hemolytic colonies on solid medium. In light of these results, the diagnostic criteria for clinical identification of A. actinomycetemcomitans and potentially related bacteria should be reevaluated. Furthermore, in studies on A. actinomycetemcomitans leukotoxin workers should now consider this toxin's ability to destroy red blood cells.

Tachykinins as enhancers of prostaglandin E2-induced intraocular inflammation (1998)

The effects of tachykinins on prostaglandin E2 (PGE2)-induced intraocular inflammation were investigated. PGE2 (0.01% or 0.1%) instillation induced iridal hyperemia and protein leakage into the aqueous humor in rabbits, but caused minimal miosis. Intravitreally injected substance P (SP) or neurokinin A (NKA), on the other hand, did not induce protein leakage into the aqueous humor in normal rabbits, but they (SP 10 micrograms/eye or NKA 50 micrograms/eye) did induce long-lasting miosis. The miotic activity of SP was about fivefold stronger than that of NKA. Intravitreally injected SP (10 micrograms/eye) but not NKA (50 micrograms/eye) increased PGE2 concentration in the aqueous humor in normal rabbits. In addition, SP (10 micrograms/eye) or NKA (50 micrograms/eye) markedly enhanced protein leakage into the aqueous humor induced by PGE2 instillation. Pretreatment with indomethacin partially blocked the enhancing effect of SP on protein leakage, while it did not block that of NKA. These results suggest that SP or NKA may enhance intraocular inflammation in vivo. However, the mechanisms of these effects of SP and NKA may be different. The enhancing effect of SP in eye inflammation may be partially due to an increased turnover of arachidonic acid into PGE2 caused by activation of the enzyme cyclooxygenase.
Impact of rare and common genetic variation in the Interleukin-1 pathway on human cytokine responses (2020)

ABSTRACT Background Interleukin(IL)-1 signaling is of major importance in human innate cytokine responses. Common variants in related genes have been linked to various inflammation-mediated diseases and stimulation-induced cytokine responses, but the role of rare variants remains to be elucidated. Methods In this study, we characterize the role of rare and common genetic variation, as identified by molecular inversion probe-based sequencing, in 48 genes related to the IL-1 pathway. Using a systems biology approach, we examined the inter-individual variability of in vitro stimulation-specific human cytokine responses from 463 healthy individuals of the Human Functional Genomics Project and assessed the role of rare and common genetic variants, separately and combined, by means of the Sequence Kernel Association Test. Results We identified strong associations for rare genetic variants in NCF4 ( adj P=7.2E −05 ) and CASP1 ( adj P=3.0E −05 ) with IL-6 production in response to PHA and LPS stimulation, respectively. In addition, common variants in IL36A and IL38 were associated to both C. albicans -induced IL-1β ( IL36A adj P=0.0442; IL38 adj P=0.0092) and IL-6 production ( IL36A adj P=0.0037; IL38 adj P=0.0082), an effect that was stronger at the subpathway level both for IL-1β ( adj P=0.0017) and IL-6 ( adj P=1.8E −04 ). The common variant signature for the IL-1β and IL-6 response to C. albicans was confirmed by an association with all anti-inflammatory genes ( adj P=1.87E −03 and adj P=5.75E −04 ), and we validated this finding for non-coding common variants. Lastly, we identified a burden of rare variants in pro-inflammatory genes and LPS-induced IL-6 production ( adj P=2.42E −04 ), and a new role for anti-inflammatory rare variants on S. aureus -stimulated IL-6 production ( adj P=6.71E −03 ). Conclusions In conclusion, we show that both common and rare genetic variation in genes of the IL-1 pathway, separately and combined, differentially influence in vitro cytokine responses to various stimuli in healthy individuals. This study therefore accentuates potential mechanisms that are translatable into new hypothesis-driven characterization of common and rare variant involvement in a wide variety of inflammatory and immunological mechanisms and diseases.
Graph Sampling with and Without Input Priors (2018)

In this paper the focus is on sampling and reconstruction of signals supported on nodes of arbitrary graphs or arbitrary signals that may be represented using graphs, where we extend concepts from generalized sampling theory to the graph setting. To recover such signals from a given set of samples, we develop algorithms that incorporate prior knowledge on the original signal when available such as smoothness or subspace priors related to the underlying graph. For reconstructing arbitrary signals, we constrain the reconstruction to the graph, and provide a consistent reconstruction method, in which both the reconstructed signal and the input yield exactly the same measurements. Given a set of graph frequency domain samples, the sampling and interpolation operations may be efficiently implemented using linear shift-invariant graph filters.
Achieving independence in logarithmic number of rounds (1987)

Simultaneous broadcast [CGMAJ is a fundamental tool in designing secure protocols for fault tolerant distributed computing. A system that supports it enables n processes to globally commit to independently chosen values (a significantly harder task than mere agreement). It is also a basic building block in a recent %ompleteness" theorem of [GMWZ].
Candidate gene-based association genetics analysis of herbage quality traits in perennial ryegrass (Lolium perenne L.) (2013)

Due to the complex genetic architecture of perennial ryegrass, based on an obligate outbreeding reproductive habit, association-mapping approaches to genetic dissection offer the potential for effective identification of genetic marker–trait linkages. Associations with genes for agronomic characters, such as components of herbage nutritive quality, may then be utilised for accelerated cultivar improvement using advanced molecular breeding practices. The objective of the present study was to evaluate the presence of such associations for a broad range of candidate genes involved in pathways of cell wall biosynthesis and carbohydrate metabolism. An association-mapping panel composed from a broad range of non-domesticated and varietal sources was assembled and assessed for genome-wide sequence polymorphism. Removal of significant population structure obtained a diverse meta-population (220 genotypes) suitable for association studies. The meta-population was established with replication as a spaced-plant field trial. All plants were genotyped with a cohort of candidate gene-derived single nucleotide polymorphism (SNP) markers. Herbage samples were harvested at both vegetative and reproductive stages and were measured for a range of herbage quality traits using near infrared reflectance spectroscopy. Significant associations were identified for ~50% of the genes, accounting for small but significant components of phenotypic variance. The identities of genes with associated SNPs were largely consistent with detailed knowledge of ryegrass biology, and they are interpreted in terms of known biochemical and physiological processes. Magnitudes of effect of observed marker–trait gene association were small, indicating that future activities should focus on genome-wide association studies in order to identify the majority of causal mutations for complex traits such as forage quality.
RraA. a protein inhibitor of RNase E activity that globally modulates RNA abundance in E. coli. (2003)

Ribonuclease E (RNase E) has a key role in mRNA degradation and the processing of catalytic and structural RNAs in E. coli. We report the discovery of an evolutionarily conserved 17.4 kDa protein, here named RraA (regulator of ribonuclease activity A) that binds to RNase E and inhibits RNase E endonucleolytic cleavages without altering cleavage site specificity or interacting detectably with substrate RNAs. Overexpression of RraA circumvents the effects of an autoregulatory mechanism that normally maintains the RNase E cellular level within a narrow range, resulting in the genome-wide accumulation of RNase E-targeted transcripts. While not required for RraA action, the C-terminal RNase E region that serves as a scaffold for formation of a multiprotein degradosome complex modulates the inhibition of RNase E catalytic activity by RraA. Our results reveal a possible mechanism for the dynamic regulation of RNA decay and processing by inhibitory RNase binding proteins.
Radical reductions of alkyl halides bearing electron withdrawing groups with N-heterocyclic carbene boranes (2011)

1,3-Dimethylimidazol-2-ylidene borane and 2,4-dimethyl-1,2,4-triazol-3-ylidene borane are found to be useful reagents for the reduction of alkyl iodides and bromides bearing nearby electron withdrawing substituents. Signatures of radical chain reactions are seen in many cases, but ionic reductions may also be occurring with some substrates. The reagents are attractive because of their low molecular weight, their availability from inexpensive precursors, and their stability. Separation of the borane products from the target products is readily accomplished either with or without prior regeneration of the borane for later reuse. 2,4-Dimethyl-1,2,4-triazol-3-ylidene borane is versatile because both starting borane and its derived products can be removed by extraction with water.
Holographic grating formation in poly(spiropyran l-glutamate) (1993)

An argon-ion laser interferometer (0.3638 or 0.488 microm) wrote photoreversible holographic grating (fringe spacing 0.39-100 microm) on spin-cast thin films (5 microm thick) of poly(spiropyran l-glutamate).
Highly parallel volumetric imaging with a 32‐element RF coil array (2004)

The improvement of MRI speed with parallel acquisition is ultimately an SNR-limited process. To offset acquisition- and reconstruction-related SNR losses, practical parallel imaging at high accelerations should include the use of a many-element array with a high intrinsic signal-to-noise ratio (SNR) and spatial-encoding capability, and an advantageous imaging paradigm. We present a 32-element receive-coil array and a volumetric paradigm that address the SNR challenge at high accelerations by maximally exploiting multidimensional acceleration in conjunction with noise averaging. Geometric details beyond an initial design concept for the array were determined with the guidance of simulations. Imaging with the support of 32-channel data acquisition systems produced in vivo results with up to 16-fold acceleration, including images from rapid abdominal and MRA studies.
Nonconjugated Redox-Active Polymer Mediators for Rapid Electrocatalytic Charging of Lithium Metal Oxides (2019)

For rapid charging of lithium-ion batteries, a series of novel electrode-active materials have been studied. However, those materials suffered from replacing conventional metal oxides, such as LiCoO2 and LiFePO4, because of the strict performance criteria for commercialization. As an alternative approach, we propose the hybridization of the conventional inorganic active materials with organic redox-active polymers which are characterized by fast electrode kinetics. A new robust organic-radical-substituted polyether was synthesized to yield one of the highest charge transportabilities of nonconjugated polymers with a charge diffusion coefficient of 10–7 cm2/s. The hybrid electrode of LiFePO4 and a small amount of the polymer was able to be charged within several minutes by virtue of the electrocatalytic oxidation of the metal oxide with the radical polymer. In addition, several 4 V class organic redox-active polymers were synthesized for the hybrid with LiCoO2. After hybridization, the LiCoO2 electrodes could also be charged within several minutes with the reduced overvoltages.
Design and analysis of spatial encoding circuits for peak power reduction in on-chip buses (2005)

We propose various low-latency spatial encoder circuits based on bus-invert coding for reducing peak energy and current in on-chip buses with minimum penalty on total latency. The encoders are implemented in dual-rail domino logic with interfaces for static inputs and static buses. A spatial and temporally encoded dynamic bus technique is also proposed for higher performance targets. Comparisons to standard on-chip buses of various lengths with optimal repeater configurations at the 130-nm node show the energy-delay and peak current-delay design space in which the different encoder circuits are beneficial. A 9-mm spatially encoded static bus exhibits peak energy gains beyond that achievable through repeater optimization for a single-cycle operation at 1 GHz, with delay and energy overhead of the encoding included. For throughput-constrained buses, the spatially encoded static bus can provide up to 31% reduction in peak energy, while the spatially and temporally encoded dynamic bus yields peak current reductions of more than 50% for all bus lengths. The encoder circuits show good scaling properties since the performance penalty from encoding decreases with scaled interconnects.
