Bandwidth Analysis of Multiport Radio Frequency Systems—Part I (2016)

When multiple radio frequency sources are connected to multiple loads through a passive multiport matching network, perfect power transfer to the loads across all frequencies is generally impossible. In this two-part paper, we provide analyses of bandwidth over which power transfer is possible. Our principal tools include broadband multiport matching upper bounds, presented herein, on the integral over all frequency of the logarithm of a suitably defined power loss ratio. In general, the larger the integral, the larger the bandwidth over which power transfer can be accomplished. We apply these bounds in several ways. We show how the number of sources and loads, and the coupling between loads, affect achievable bandwidth. We analyze the bandwidth of networks constrained to have certain architectures. We characterize systems whose bandwidths scale as the ratio between the numbers of loads and sources. The first part of this paper presents the bounds and uses them to analyze loads whose frequency responses can be represented by analytical circuit models. The second part analyzes the bandwidth of realistic loads whose frequency responses are available numerically. We provide applications to wireless transmitters where the loads are antennas being driven by amplifiers. The derivations of the bounds are also included.
Engineering Quantum States of Light on Demand via Projective Measurements (2007)

We apply a theory of an optical quantum state generator to quantum information and metrology problems. We demonstrate how different entangled states of light can be constructed in an optimal way for given resources.
Active Learning for Approximation of Expensive Functions with Normal Distributed Output Uncertainty (2016)

When approximating a black-box function, sampling with active learning focussing on regions with non-linear responses tends to improve accuracy. We present the FLOLA-Voronoi method introduced previously for deterministic responses, and theoretically derive the impact of output uncertainty. The algorithm automatically puts more emphasis on exploration to provide more information to the models.
Journey to the past (2006)

While the Internet community recognized early on the need to store and preserve past content of the Web for future use, the tools developed so far for retrieving information from Web archives are still difficult to use and far less efficient than those developed for the "live Web." We expect that future information retrieval systems will utilize both the "live" and "past Web" and have thus developed a general framework for a past Web browser. A browser built using this framework would be a client-side system that downloads, in real time, past page versions from Web archives for their customized presentation. It would use passive browsing, change detection and change animation to provide a smooth and satisfactory browsing experience. We propose a meta-archive approach for increasing the coverage of past Web pages and for providing a unified interface to the past Web. Finally, we introduce query-based and localized approaches for filtered browsing that enhance and speed up browsing and information retrieval from Web archives.
Body Mass Index Mediates the Relationship between the Frequency of Eating Away from Home and Hypertension in Rural Adults: A Large-Scale Cross-Sectional Study (2022)

This study was conducted to investigate the association of eating away from home (EAFH) frequency with hypertension and to explore whether the association was mediated by BMI. A total of 29,611 participants were selected from the Henan Rural Cohort Study. Data on the frequency of EAFH were obtained by face-to-face questionnaires. The relationship between EAFH frequency and blood pressure was evaluated by linear regression. Logistic regression and restricted cubic spline were used to assess the association between EAFH frequency and hypertension, and the mediation effect of BMI on the relationship was performed. There were pronounced associations between the frequency of EAFH and blood pressure (P trend < 0.001) in the total population and men. Compared with the population with 0 times EAFH per week, the multivariate odds ratios (ORs) and 95% confidence intervals (95% CIs) for hypertension of the group with 7 times or more EAFH per week were 1.673 (1.482−1.889) for the total population and 1.634 (1.413−1.890) for men. A nonlinear dose-response relationship was detected between the frequency of EAFH and hypertension (p < 0.001), and the relationship was partially mediated by BMI. The proportion explained was 21.3% in the total population and 25.4% in men. The current study indicated that EAFH was associated with rising blood pressure and increased risk of hypertension and BMI partially mediated the relationship.
Source-Side State Feedback-Based Electrolytic Capacitor-less Inverter Drive System Using One Sample Predictive State Observer (2022)

In an electrolytic capacitor-less inverter, source current harmonics are caused by LC-circuit resonance, and the source power factor deteriorates. Therefore, an inverter must reduce harmonics control without additional circuits. This paper proposes a source current control method to reduce source current harmonics in a three-phase to three-phase electrolytic capacitor-less inverter of a permanent magnet synchronous motor drive. The proposed method consists of a source current control using the full-state feedbacks of a LC-resonance state observer. The validity of the proposed method is confirmed through experimental results.
Workflow interoperability standards for the Internet (2000)

Efforts toward defining a standard for workflow interoperability began in 1994 with the Workflow Reference Model from the Workflow Management Coalition (WfMC). From that model other standardization efforts have evolved: from OMG's jointflow specification to the simple Workflow Access Protocol. The WfMC's Wf-XML focuses on a simple subset of SWAP for a first version of a standard, with the aim of future extension.
Phase-separation of miscible liquids in a centrifuge (2007)

We show that a liquid mixture in the thermodynamically stable homogeneous phase can undergo a phase-separation transition when rotated at sufficiently high frequency ω . This phase-transition is different from the usual case where two liquids are immiscible or where the slow sedimentation process of one component (e.g. a polymer) is accelerated due to centrifugation. For a binary mixture, the main coupling is due to a term <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mo>∝</mml:mo> <mml:mi mathvariant="normal">Δ</mml:mi> <mml:mi>ρ</mml:mi> <mml:msup> <mml:mrow> <mml:mo stretchy="false">(</mml:mo> <mml:mi>ω</mml:mi> <mml:mi>r</mml:mi> <mml:mo stretchy="false">)</mml:mo> </mml:mrow> <mml:mn>2</mml:mn> </mml:msup> </mml:math> , where Δ ρ is the difference between the two liquid densities and r the distance from the rotation axis. Below the critical temperature there is a critical rotation frequency <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:msub> <mml:mi>ω</mml:mi> <mml:mi>c</mml:mi> </mml:msub> </mml:math> , below which smooth density gradients occur.

These findings may be relevant to various separation processes and to the control of chemical reactions, in particular their kinetics.
Cell Cycle and Biochemical Effects of PD 0183812 (2001)

Progression through the G1 phase of the cell cycle requires phosphorylation of the retinoblastoma gene product (pRb) by the cyclin D-dependent kinases CDK4 and CDK6, whose activity can specifically be blocked by the CDK inhibitor p16(INK4A). Misregulation of the pRb/cyclin D/p16(INK4A) pathway is one of the most common events in human cancer and has lead to the suggestion that inhibition of cyclin D-dependent kinase activity may have therapeutic value as an anticancer treatment. Through screening of a chemical library, we initially identified the [2,3-d]pyridopyrimidines as inhibitors of CDK4. Chemical modification resulted in the identification of PD 0183812 as a potent and highly selective inhibitor of both CDK4 and CDK6 kinase activity, which is competitive with ATP. Flow cytometry experiments showed that of the cell lines tested, only those expressing pRb demonstrated a G1 arrest when treated with PD 0183812. This arrest correlated in terms of incubation time and potency with a loss of pRb phosphorylation and a block in proliferation, which was reversible. These results suggest a potential use of this chemical class of compounds as therapeutic agents in the treatment of tumors with functional pRb, possessing cell cycle aberrations in other members of the pRb/cyclin D/p16(INK4A) pathway.
High resolution optical projection tomographic microscopy for 3D tissue imaging (2011)

Optical projection tomography (OPT) requires a large depth of field (DOF) of a low numerical aperture (NA) lens resulting in low resolution. However, DOF of a high NA objective can be extended by scanning the focal plane through the sample. This extended DOF image is called pseudoprojection, which is used by optical projection tomographic microscope (OPTM) for tomographic reconstruction. The advantage of OPTM is the acquisition of relatively high resolution and large depth of field concurrently. This method requires the working distance of the lens to be larger than the size of the sample, so proper lens should be chosen for samples of different sizes. In this paper, we imaged hematoxylin stained muntjac cells inside capillary tube with two different sizes. Two objective lenses with different NA are used for these two tubes. Experimental results show that resolution improves over 10 times in OPTM compared to conventional OPT, which make it possible for OPTM technique to resolve sub-cellular features for large samples. Therefore, OPTM can be used for 3D histological analysis of hematoxylin & eosin (H&E) stained biopsy specimen with sub-cellular resolution in the future.
Insights into the ruthenium-catalysed selective reduction of cardanol derivatives via transfer hydrogenation: a density functional theory study (2023)

The detailed mechanism for ruthenium-catalysed selective reduction of cardanol derivatives by transfer hydrogenation has been fully characterised at the B3PW91-D3/ECP2/PCM//B3PW91/ECP1 level of density functional theory.
Phosphoinositide-3-kinase gamma/delta isoform signalling defines a mixed T cell severe asthmatic endotype (2017)

Severe asthma remains a clinical burden despite the emergence of antibody therapies. Complex disease drivers, which shift between T2, T1 and T17 driven inflammation, termed mixed T cell asthma, likely contribute to ineffective disease control in this population. Here we dissect the mechanisms underlying severe asthma to reveal a potential role (s) for both PI3Kgamma and delta (PI3Kγ and δ) isoform activity in asthmatics with a mixed T cell endotype. A PI3Kγδ gene signature was generated from next generation sequencing of IL-8/GM-CSF-stimulated monocytes where PI3Kγδ signalling was inhibited. This mRNA signature was used to interrogate the Ubiopred database. We observed a strong association between PI3Kγδ pathway activity, severity and mixed eosinophil and neutrophil sputum granulocyte content. To further support a role of PI3Kγδ in a mixed T cell asthma phenotype we demonstrated the following. 1) PI3Kδ-dependent allergen stimulation of mixed T cell activity in grass pollen atopic blood. 2) PI3Kδ-mediated inhibition of IL-5, IFNγ and IL-17 production from asthma patient blood T cells. 3) PI3Kγ mediated signalling was required for activation of asthmatic eosinophil and neutrophil populations. 4) Activity of an inhaled PI3Kγδ dual inhibitor in a rodent in vivo model of steroid resistant allergy/infection on mixed T cell mediator release, granulocyte influx and airways hyperresponsiveness. These data identify a population of mixed T cell asthma patients with increased PI3Kγδ activity and suggest a therapeutic potential of an inhaled PI3K dual inhibitor.
Seeing Beyond Appearance - Mapping Real Images into Geometrical Domains for Unsupervised CAD-based Recognition (2019)

While convolutional neural networks are dominating the field of computer vision, one usually does not have access to the large amount of domain-relevant data needed for their training. Therefore, it has become common practice to use available synthetic samples along domain adaptation schemes to prepare algorithms for the target domain. Tackling this problem from a different angle, we introduce a pipeline to map unseen target samples into the synthetic domain used to train task-specific methods. Denoising the data and retaining only the features these recognition algorithms are familiar with, our solution greatly improves their performance. As this mapping is easier to learn than the opposite one (i.e., to generate realistic features to augment the source samples), we demonstrate how our whole solution can be trained purely on augmented synthetic data and still performs better than methods trained with domain-relevant information (e.g., real images or realistic textures for the 3D models). Applying our approach to object recognition from texture-less CAD data, we present a custom generative network which fully utilizes the purely geometrical information to learn robust features and to achieve a more refined mapping for unseen color images.
pH‐Controlled Assemblies of Dimethyltin‐Functionalized 9‐Tungstophosphates with Guanidinium as Structure‐Directing Cation (2010)

Abstract Aqueous reaction of (CH 3 ) 2 SnCl 2 with Na 9 [ A ‐α‐PW 9 O 34 ] in a 3:1 ratio with [C(NH 2 ) 3 ] + as structure‐directing agent resulted in three distinct assemblies of dimethyltin‐functionalized tungstophosphates depending on the pH: [{(CH 3 ) 2 Sn(H 2 O)}{(CH 3 ) 2 Sn}( A ‐α‐PW 9 O 34 )] 5– ( 1 ) at pH = 4.5; [{(CH 3 ) 2 Sn(H 2 O) 2 }{(CH 3 ) 2 Sn(H 2 O)} 2 ( A ‐α‐PW 9 O 34 )] 3– ( 2 ) at pH = 3.0; and [{(CH 3 ) 2 Sn(H 2 O)} 3 ( A‐ α‐PW 9 O 34 )] 3– ( 3 ) at pH = 2.0. All three compounds have been characterized in the solid‐state by elemental and thermal analyses, infrared spectroscopy and single‐crystal X‐ray diffraction. The [ A ‐α‐PW 9 O 34 ] 9– trilacunary fragments have three {(CH 3 ) 2 Sn} 2+ groups anchored on the vacant sites via two Sn–O(W) bonds each and they are linked into guanidinium‐templated, extended architectures with dimensionalities increasing with the acidity of the reaction media. The structure of 1 consists of a 1‐dimensional arrangement of alternating [ A ‐α‐PW 9 O 34 ] 9– subunits and trans ‐(CH 3 ) 2 SnO 4 bridging moieties, whereas compounds 2 and 3 are 2‐ and 3‐dimensional assemblies, respectively, of monomeric [{(CH 3 ) 2 Sn} 3 ( A ‐α‐PW 9 O 34 )] 3– building blocks connected via weak intermolecular Sn–O=W bridges.
Hybrid Mesoporous Silica Nanoparticles with pH‐Operated and Complementary H‐Bonding Caps as an Autonomous Drug‐Delivery System (2014)

Mesoporous silica nanoparticles (MSNPs) are functionalized with molecular-recognition sites by anchoring a triazine or uracil fragment on the surface. After loading these MSNPs with dyes (propidium iodide or rhodamine B) or with a drug (camptothecin, CPT) they are capped by the complementary fragments, uracil and adenine, respectively, linked to the bulky cyclodextrin ring. These MSNPs are pH-sensitive and indeed, the dye release was observed at acidic pH by continuously monitored fluorescence spectroscopy studies. On the other hand, no dye leakage occurred at neutral pH, hence meeting the non-premature requirement to minimize side effects. In vitro studies were performed and confocal microscopy images demonstrate the internalization of the MSNPs and also dye release in the cells. To investigate the drug-delivery performance, the cytotoxicity of CPT-loaded nanoparticles was tested and cell death was observed. A remarkably lower amount of loaded CPT in the MSNPs (more than 40 times less) proved to be as efficient as free CPT. These results not only demonstrate the drug release after pore opening under lysosomal pH, but they also show the potential use of these MSNPs to significantly decrease the amount of the administered drug.
Microfluidic System for Detection of Viral RNA in Blood Using a Barcode Fluorescence Reporter and a Photocleavable Capture Probe (2017)

A microfluidic sample preparation multiplexer (SPM) and assay procedure is developed to improve amplification-free detection of Ebola virus RNA from blood. While a previous prototype successfully detected viral RNA following off-chip RNA extraction from infected cells, the new device and protocol can detect Ebola virus in raw blood with clinically relevant sensitivity. The Ebola RNA is hybridized with sequence specific capture and labeling DNA probes in solution and then the complex is pulled down onto capture beads for purification and concentration. After washing, the captured RNA target is released by irradiating the photocleavable DNA capture probe with ultraviolet (UV) light. The released, labeled, and purified RNA is detected by a sensitive and compact fluorometer. Exploiting these capabilities, a detection limit of 800 attomolar (aM) is achieved without target amplification. The new SPM can run up to 80 assays in parallel using a pneumatic multiplexing architecture. Importantly, our new protocol does not require time-consuming and problematic off-chip probe conjugation and washing. This improved SPM and labeling protocol is an important step toward a useful POC device and assay.
On the performance of practical VIP-MIMO-OFDM systems for future wireless LAN (2006)

This paper examines the practical feasibility of the proposed Varying Interleave Patterns (VIP)-MIMO scheme in accordance with OFDM-based IEEE802.11a standards and IEEE802.11n channel models for future wireless LAN. For the sake of acquiring more diversity gain in the VIP-MIMO scheme using spatial multiplexing, both interleave size and the number of iterative decoding are of special importance although an iterative decoder gives rise to delays. IEEE802.11a standards require sending an ACK frame within a specific period, and IEEE802.11 future standards including IEEE802.11n are also demanding the period as a backward compatibility. The simulation results of a VIP-MIMO-OFDM system with an iterative decoder considering the above points indicate significant improvements in S/N over a legacy system. We therefore clarify the promising faculty of the VIP-MIMO-OFDM system.
Ceramic Surface Reactions and Carbon Retention during Non‐Oxidative Binder Removal Al 2 O 3 /Poly(methyl methacrylate) at 20 ° –700 ° C (1994)

Neat poly(methyl methacrylate) (PMMA) thermally decomposes in oxygen‐free environments with negligible production of nonvolatile residue. Compacts of α‐alumina powder containing PMMA that are fired in a non‐oxidative ambient, however, retain appreciable amounts of char. Fourier transform infrared (FTIR) spectroscopy and evolved gas analysis utilizing mass spectral detection were employed to probe the chemical mechanism that initiates the production of organic residue from non‐oxidatively fired PMMA/alumina bodies. We find that binding of organic groups to alumina particles is caused by a sponification reaction between either the ester groups of PMMA or thermally evolved PMMA fragments (including MMA) and hydroxyl groups on alumina particle surfaces. Isolated alumina surface hydroxyl groups were found to be much more reactive than mutually hydrogen‐bonded alumina surface hydroxyl groups in producing surface‐bound organic groups. This surface‐carboxylate‐forming reaction anchors organic residue to the inorganic surfaces to temperatures above the unzipping temperature of the polymer and leads to retention of organic fragments in the compacts at temperatures where neat PMMA has completely volatilized. Subsequent transformations of these surface‐bound organic fragments at high temperatures produce the nonvolatile carbonaceous residues, which are retained in the fired alumina compacts. We demonstrate that unsaturation in the carboxylate side chain plays an important role in this stage of the process in increasing the char yield. We also show that the char yields are proportional to surface carboxylate coverage but that it is difficult to control surface carboxylate coverage by thermal pretreatments of the alumina powders.

Scanning characteristics of spherical dome antenna composed of arcing dipole array antennas including the effects of mutual coupling between elements (1988)

Abstract For a beam scanning at high speed over a wide angle, a dome antenna has been proposed. Past research on the dome antenna treated the dome parts as an ideal lens. However, the concrete arrangement of antenna elements outside and inside the dome and their mutual coupling have not been considered. Based on our past work on the electromagnetic field inside a concave spherical surface, this paper describes the results of analysis performed on the most fundamental dome antenna composed of arcing array antennas. For the array elements we considered dipole antennas. We obtained the radiation characteristics considering the mutual coupling among the elements of the radiators on the convex surface, the elements of the collector on the concave surface, and the coupling between the elements of the collector and the elements of the primary radiator. We determined the excitation currents in the elements of the primary radiator so that the currents in the elements of the radiator become co‐phase and uniform amplitude along the direction of the main beam. We obtained the radiation characteristics, and confirmed that over the range from 0 to 110°, beam scanning at almost a constant gain was possible. Next, we suppressed the levels of the sidelobes. We showed that up to a maximum of 18 dB, we suppressed the levels of the sidelobes compared to the co‐phase excitation. Finally, we discussed the influence of the mutual coupling between the elements of the radiator and the elements of the collector on the directivity.
Tea Polyphenols Regulate Key Mediators on Inflammatory Cardiovascular Diseases (2009)

Tea polyphenols known as catechins are key components with many biological functions, including anti-inflammatory, antioxidative, and anticarcinogenic effects. These effects are induced by the suppression of several inflammatory factors including nuclear factor-kappa B (NF-kappaB). While these characteristics of catechins have been well documented, actions of catechins as mediators on inflammation-related cardiovascular diseases have not yet been well investigated. In this article, we reviewed recent papers to reveal the anti-inflammatory effects of catechins in cardiovascular diseases. In our laboratory, we performed oral administration of catechins into murine and rat models of cardiac transplantation, myocarditis, myocardial ischemia, and atherosclerosis to reveal the effects of catechins on the inflammation-induced ventricular and arterial remodeling. From our results, catechins are potent agents for the treatment and prevention of inflammation-related cardiovascular diseases because they are critically involved in the suppression of proinflammatory signaling pathways.
Surveillance for Influenza Admissions Among Children Hospitalized in Canadian Immunization Monitoring Program Active Centers, 2003–2004 (2006)

Healthy young children and children with chronic conditions are at risk for serious illness with influenza. Ongoing surveillance is needed to evaluate the impact of changing immunization recommendations on the burden of influenza illness in children.
