Accessing the Internet through Moving Networks (2007)

The success of cellular communications networks shows the interest of users in mobility. Host mobility support in IP networks is a first step in the adaptation of these networks to the needs of users in this field. But, there exists also the need of supporting the movement of a complete network that changes its point of attachment to the fixed infrastructure. This paper describes the architecture designed in the EU DAIDALOS II project to provide Internet access through moving networks. The designed moving networks architecture support the following main features: route optimisation, multicast traffic delivery, security and authentication integration, end-to-end QoS and interaction with localised mobility management solutions.
XPS surface analysis of V-P mixed oxide catalysts for the selective oxidation of butane. (1989)

PIV組成比(原子比)がo.75～1.70の触媒を調製して,XPSによる表面分析を行い,触媒表面の酸化状態や表面組成を調べ,ブタン酸化触媒能に与える影響について検討した。触媒の表面状態は,触媒調製法や焼成条件(温度,時間,雰囲気)またP/V(パルク)比により大きく異なり,N2気流中で焼成した場合,触媒表面のバナジウムの酸化数はほぼ四価であったが空気中で焼成すると五緬が主となった。ブタン酸化反応後の触媒表面状態には,PIV(バルク)比の影響が顕著に現われ,N2気流中焼成した触媒は,P/V＜1.0において表面バナジウムの一部が五価に酸化された。これに対し空気中焼成した触媒は,表面に多く存在するV5+がP/V＞1.0においてブタン酸化反応糊気中,V4+に還元された。このようにリンが過剰に存在すると,触媒反応時にV4+按定化させる効果が顕著であった。一方,触媒表面のリンの酸化数は,焼成雰囲気によらず五価と考えられるが,PIV比が1.0～1.1付近においてBE値にシフトが見られ,リンの結合状態がP/V比により異なるものと示唆される。V-P系触媒の仕込(バルク)組成と裏面組成との関係を調べたところ,パルク組成が0.85を越えるとリンが多くなり,さらに表面組成がプラトー(PIV=1.6～1.9)になる領域が見られた。このような触媒を用いてブタン酸化反応を行ったところ,無水マレイン酸(MA)選択性は表面組成に大きく依存し,表面組成がプラトーとなる領域において最大となった。したがって,選択的なMA生成活性はバルク中に(VO)2P207相を含み,その表面にリンが豊富なプラトー表面層(P/V=1.6～1・9)が形成したものが有効と示唆され,この表面層がMA生成に選択的な表面を提供するものと考えられる。

Microwave spectra of mixtures of non-absorbing solid particles and absorbing liquids (2008)

Microwave spectroscopy of condensed phases is sensitive to sample compositional factors such as water or fat content, solids content and salt concentration which leads to applications for in-line process monitoring. In this paper we show that microwave spectra can also be sensitive to sample structure at fixed composition which has implications for analytical applications involving samples which are multi-phase mixtures. We have measured microwave spectra for samples containing a constant volume fraction of non-absorbing glass spheres immersed within an absorbing liquid phase; the only difference between samples is the mean diameter of the glass spheres. The large differences in the spectra for different diameters is successfully modelled in terms of the relative volume fractions of glass and absorbing liquid within a measurement penetration depth adjacent to the microwave measuring probe.
Expanding the useful range of ionic liquids: melting point depression of organic salts with carbon dioxide for biphasic catalytic reactions (2006)

Large and previously unreported melting point depressions (even exceeding DeltaTm of 100 degrees C) were observed for simple ammonium and phosphonium salts in the presence of compressed CO2, bringing them well within the range of typical ionic liquids; possible applications include biphasic catalysis in IL/scCO2 systems as demonstrated for rhodium complex catalyzed hydrogenation, hydroformylation, and hydroboration of 2-vinyl-naphthalene using a CO2-induced molten sample of [NBu4][BF4] as a catalyst phase at temperatures in the range of 55-75 degrees C, i.e. 100 degrees C below the normal melting point of the organic salt.
Magnetoelastic microsensors for environmental monitoring (2002)

This paper reports on the operational characteristics, and application, of a new passive wireless micro-sensor platform based on magnetoelastic materials. We have used micro-electro-discharge machining (micro-EDM) to fabricate magnetoelastic micro-sensor arrays. In response to a time varying magnetic field, amorphous ferromagnetic magnetoelastic thin films efficiently convert magnetic energy into elastic energy. The elastic waves mechanically deform the sensor which, for ribbon shaped elements, has a characteristic mechanical resonant frequency that is a function of its length, elasticity, and material density. Since the magnetoelastic material is also magnetostrictive, as the sensor mechanically deforms it generates magnetic flux that extends remotely about the device, which can be detected by a pickup coil. The remote query capability of this sensor technology enables a host of new monitoring applications including in-situ and in-vivo experiments. The bare sensor is capable of measuring ambient temperature and pressure, liquid density, liquid viscosity, and fluid flow velocity. The sensor platform can be used for chemical sensing when used in combination with mass-changing chemically responsive layers. Using an array of the magnetoelastic sensors one can determine multiple environmental conditions simultaneously.
Catoptric Surface (2018)

The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.
Cars, calls, and cognition (2010)

Conversing on cell phones while driving an automobile is a common practice. We examine the interference of the cognitive load of conversational dialog with driving tasks, with the goal of identifying better and worse times for conversations during driving. We present results from a controlled study involving 18 users using a driving simulator. The driving complexity and conversation type were manipulated in the study, and performance was measured for factors related to both the primary driving task and secondary conversation task. Results showed significant interactions between the primary and secondary tasks, where certain combinations of complexity and conversations were found especially detrimental to driving. We present the studies and analyses and relate the findings to prior work on multiple resource models of cognition. We discuss how the results can frame thinking about policies and technologies aimed at enhancing driving safety.
Organic inorganic hybrid materials-2002 : symposium held April 1-5, 2002, San Francisco, California, U.S.A. (2002)

Interest in hybrid materials has grown substantially as researchers recognize that the ability to tailor the organization of organic/inorganic composites at nanometer length scales provides access to materials with properties nonlinearly related to the bulk properties of the individual components. Efforts to tailor nanostructure through the design, synthesis and processing of nanocomponents and the investigation of intermediate and final properties have intensified, driven in part by the roadmap that guides miniaturization in the electronics and photonics industries. This book creates a forum for researchers involved in the synthesis, characterization, processing and properties analysis of organic/inorganic hybrid materials to develop ideas and points of view. Topics include: well-defined nanobuilding blocks-precursors for hybrids; strategies to functional lamellar hybrid materials; chemical strategies for the design of new hybrids; biomaterials, biogels and biomimetic approaches of materials; templated growth to nano/meso/macrostructured hybrid materials; advanced processing for hybrid materials; processing and properties of functional hybrids (optical, electrical and mechanical) and properties of hybrids (optical, electrical, mechanical and catalysis).
S-Nitrosylation of Dynamin-Related Protein 1 Mediates Mutant Huntingtin-Induced Mitochondrial Fragmentation and Neuronal Injury in Huntington's Disease (2013)

Our findings indicate that aberrant S-nitrosylation of Drp1 is a prominent pathological feature of neurodegenerative diseases such as AD and HD. Moreover, the SNO-Drp1 signaling pathway links mutHTT neurotoxicity to a malfunction in mitochondrial dynamics, resulting in neuronal synaptic damage in HD.
Probing and Controlling Liquid Crystal Helical Nanofilaments (2015)

We report the first in situ measurement of the helical pitch of the helical nanofilament B4 phase of bent-core liquid crystals using linearly polarized, resonant soft X-ray scattering at the carbon K-edge. A strong, anisotropic scattering peak corresponding to the half-pitch of the twisted smectic layer structure was observed. The equilibrium helical half-pitch of NOBOW is found to be 120 nm, essentially independent of temperature. However, the helical pitch can be tuned by mixing guest organic molecules with the bent-core host, followed by thermal annealing.
Traffic measurement and analysis in an organic enterprise data center (2013)

Enterprise data centers (EDCs) are critical infrastructure to large enterprises, government agencies, research institutions, etc. They are used to support a variety of off-the-shelf and customized services. EDCs are different from cloud data centers (CDCs) in two major aspects. Firstly, an EDC is usually built over time and consists of old and new equipment. Secondly, the type of services and applications in EDCs are quite different from those in CDCs. Therefore, we expect that the traffic characteristics in EDCs would also be different from those in CDCs. While most existing data center measurements were from CDCs, we performed extensive traffic measurement and analysis in an EDC that provided multiple services to over a million users. We present the data center architecture, measurement methodology, measurement results, and analysis. The results include traffic matrix, traffic distribution, flow characteristics, and TCP characteristics. Our research reveals that the traffic characteristics in the EDC are indeed quite different from the reported results in CDCs. For example, the traffic matrix tends to be sparse rather than all-to-all. Based on the analysis we provide a few guidelines for EDC design, optimization, and anomaly detection. As the first most extensive study on EDC traffic, our work provides valuable information to future EDC design and implementation, and also helps researchers develop insights into the differences and similarities between EDCs and CDCs.
Abstract LB-102: A tumor-specific tissue penetrating peptide inhibits metastasis (2014)

Abstract Neuropilin-binding tumor-penetrating peptides increase vascular and tissue permeability in tumors, allowing drugs conjugated to the peptide and even free drugs co-injected with the peptide to widely distribute within the tumor tissue (Sugahara KN et al, Cancer Cell 16:510, 2009; Science 328:1031, 2010). Thus, the peptides provide an elegant way to enhance therapeutic index of anti-cancer drugs. However, the ability of the peptides to increase vascular permeability has raised concerns that the peptides might enhance metastasis by promoting cell seeding from the primary tumor. Here, we show a recent unexpected finding that a prototypic tumor-penetrating peptide, iRGD (amino acid sequence: CRGDK/RGPD/EC), is a potent metastasis inhibitor. iRGD did not cause systemic tumor cell dissemination or metastasis in mice bearing breast tumors with low metastatic potential. iRGD treatment of mice bearing aggressive orthotopic pancreatic tumors resulted in significant decrease in spontaneous metastasis formation. Primary tumor growth was not affected by the treatment. Another tumor-penetrating peptide, iNGR, also inhibited metastasis, while conventional RGD peptides or a scrambled iRGD peptide that lack neuropilin affinity failed to do. These results indicate that the anti-metastatic effect of iRGD was dependent on its neuropilin-binding peptide motif. In vitro migration assays demonstrated that iRGD potently inhibits tumor cell migration and serves as a chemorepellent of tumor cells in a neuropilin-dependent manner. Chemorepulsion assays based on live cell imaging confirmed the findings, and further demonstrated that iRGD dramatically collapses tumor cell protrusions leading to an instantaneous retraction of tumor cells from iRGD-bound surfaces. Our finding refutes the hypothesis that iRGD may cause enhanced metastasis. The mechanism of the anti-metastatic effect may involve neuropilin-mediated chemorepulsion of tumor cells. Collectively, iRGD may simultaneously achieve tumor-specific drug delivery and metastasis inhibition when utilized for cancer treatment. Citation Format: Kazuki N. Sugahara, Gary B.

A new short practical quality of life questionnaire for use in Head and Neck Oncology outpatient clinics (1998)

A new short questionnaire to assess the quality of life of head and neck patients has been designed at the University of Liverpool Head and Neck Oncology Department. The questionnaire is short, simple and can be easily completed by a patient whilst in the waiting room before consultation. It is filled in 6 months after completion of treatment and shows very good correlation with the standard long exhaustive questionnaires that are difficult to complete on every patient in a busy National Health Service clinic. The University of Liverpool questionnaire provides a simple score from 0%-100% which should prove valuable in the assessment of quality of care and help with decisions regarding treatment options in head and neck cancer patients.
Macro Cell Switching of Transmit Antennas in Distributed Antenna Transmission (2021)

In this paper, a macro cell switching scheme for distributed antennas is proposed. In conventional distributed antenna transmission (DAT), the macro cell to which each antenna belongs is fixed. Though a cell-free system has been investigated because of its higher system throughput, the implementation cost of front-hauls can be excessive. To increase the flexibility of resource allocation in the DAT with moderate front-haul complexity, we propose the macro cell switching of distributed antennas (DAs). In the proposed scheme, DAs switch their attribution macro cells depending on the amount of pre-assigned connections. Numerical results obtained through computer simulation show that the proposed scheme realizes a better system throughput than the conventional system, especially when the number of user equipments (UEs) is smaller and the distance between DAs are larger.

Analysis of Collaborative Learning Behaviors and the Roles of Collaborative Learning Agent (2004)

Collaborative learning is one of the learning approaches that promote interactions and complementary roles among learners in order to maximize achievement of individual learners’ and groups’ goals. The current research inquired the collaborative e-learning models and behaviors that can improve cognitive and social interactions demanded in the various platforms such as personal computing, mobile computing, and digital TV environments. Furthermore, it suggested the roles of collaborative learning agent.
Analysis of magnetic noise in lead overlaid giant magnetoresistive read heads (2002)

Thermally induced magnetic noise in giant magnetoresistive (GMR) read heads was characterized with both contiguous junction and lead overlaid design using an integrated spectral method. At 0.25 μm magnetic read width and 4 mA bias current, magnetic noise is twice as large as Johnson noise for lead overlaid design, while it is comparable with Johnson noise for contiguous junction design. The head signal-to-noise ratio gain of 2–3 dB with lead overlaid design is less than an amplitude gain of 50%–100% since it is limited by increased magnetic noise, which roughly scales with amplitude. Magnetic noise increases with bias current at a much faster rate than Johnson noise. Higher magnetic noise is attributed to weaker longitudinal bias field associated with the lead overlaid design. Fortunately, magnetic noise does not limit system level signal to noise ratio since media transition noise is dominant. However, it is projected that magnetic noise will account for an increased portion of total noise power at higher areal densities.
Promoting Joint Attention with Computer Supported Collaboration in Children with Autism (2016)

There exists mounting evidence in favor of computer supported autism interventions at the individual level. However, the potential benefits of using computer supported collaboration to encourage social interactions between individuals with autism and typically developed individuals are underexplored, particularly in developing regions. We present an exploratory study of a collaborative gesture-based application, Balloons. The application encourages joint attention, which is defined as the shared attention between two individuals towards the same object. Using mixed methods, we evaluated Balloons for three weeks in New Delhi with ten medium-low functioning autistic children. Our findings suggest that employing CSC interventions for children with autism in India provide (a) observable improvements in social interaction with typically developed peers, (b) the opportunity to customize and individualize intervention to cater to a large spectrum of children and (c) the potential opportunity of reducing fears of certain objects.
Ultralow Temperature Synthesis of Ordered Hexagonal Smaller Supermicroporous Silica Using Semifluorinated Surfactants as Template (2006)

Ordered hexagonal smaller supermicroporous silica (JLU-14L and JLU-11L) has been successfully synthesized at ultralow temperature (0 approximately -20 degrees C) by semifluorinated surfactants, which is extensively investigated by X-ray diffraction, N2 adsorption, and transmission electron microscopy. X-ray diffraction shows that the peak intensity of the samples increases with decreasing synthesis temperatures in the range of 0 approximately -20 degrees C, indicating that the ordering of porous silica improves with decreasing synthesis temperature. N2 adsorption/ desorption isotherms show that JLU-14L has both ordered smaller hexagonal supermicropores (1.27 and 1.28 nm) and disordered micropores (0.67 nm). Such hierarchically porous materials with micro/supermicroporosity should be potentially important for fast diffusion of reactants and products in catalytic reactions. The ultralow temperature synthesis is a crucial factor for the formation of ordered smaller supermicropores and the control of microporosity in JLU-14L.
Synthesis of Substituted Phenazines via Palladium-Catalyzed Aryl Ligation (2011)

Lysosomal response of a murine macrophage-like cell line persistently infected with Coxiella burnetii (1983)

The lysosomal response of a murine macrophage-like tumor cell line (J774) during persistent infection with Coxiella burnettii was examined. By using acid phosphatase as a lysosomal marker, it was shown that phagosome-lysosome fusion occurred in J774 cells persistently infected with C. burnetii. This observation was verified using thorium dioxide, an electron-dense compound that is sequestered in secondary lysosomes. The phagolysosomes contained viable replicating rickettsiae. Spectrofluorometric analysis indicated that the phagolysosomal pH of persistently infected cells was acidic. In attempts to correlate rickettsial survival with lysosome function, the activities of several lysosomal enzymes were assayed in both infected and uninfected cells. Activities of acid phosphatase and beta-acetylglucosaminidase were not significantly altered during infection. However, infected cells appeared to display slightly higher intracellular lysozyme, beta-glucuronidase, and beta-galactosidase activities.
