description: We describe the architecture and implementation of our comprehensive multi-platform collaboration framework known as Columbia InterNet Extensible Multimedia Architecture (CINEMA). It provides a distributed architecture for collaboration using synchronous communications like multimedia conferencing, instant messaging, shared web-browsing, and asynchronous communications like discussion forums, shared files, voice and video mails. It allows seamless integration with various communication means like telephones, IP phones, web and electronic mail. In addition, it provides value-added services such as call handling based on location information and presence status. The paper discusses the media services needed for collaborative environment, the components provided by CINEMA and the interaction among those components.

description: This thesis investigates an African diaspora Christian community in Calgary, Alberta, to examine the role of the church within Canada's new burgeoning African population. Using social scientific methods this study answers three pertinent questions: 1. How does this particular community relate to the comprehensive African diaspora?; 2. How does the theory and praxis of this African diaspora church correlate with worldwide and African Christianity?; and, 3. What is the role and significance of the church within Canada's African diaspora? Employing the diffusion of innovations as a guide, this study investigates the success of Pentecostalism across the continent and within the African diaspora; multiplying African conceptions of the Prosperity Gospel, demonic forces, power, church services, gender, and a missional and marketing focus. Additionally, it will be demonstrated that the church also serves to cultivate a thriving Christian Pan­Africanism, while providing an avenue by which to deal with discrimination.

description: Since the beginning of scientific operations in 2003, more than 20 extra-galactic sources have been detected with H.E.S.S. (High Energy Stereoscopic System) at very high energies (VHE): apart from the starburst galaxy NGC 253, all of them are active galactic nuclei (AGNs). BL Lac objects are by far the dominant AGN sub-class in the H.E.S.S. extra-galactic sky, but two radio-galaxies and one flat-spectrum radio quasar (FSRQ) have been detected as well. The study of extra-galactic VHE emitters will be improved in the near future by the completion of a fifth 24m-diameter telescope (H.E.S.S. II). In this talk, a review of the AGNs seen by H.E.S.S. will be given, including the latest results achieved, namely the detection of VHE emission from the blazars 1RXS J101015.9-311909, SHBL J001355.9-185406, 1ES 1312-423, AP Lib and the BL Lac candidate HESS J1943+213.

Are sex differences in force steadiness due to dissimilar motor unit activity between men and women?
Creators: name: Brown, Ruth Emily
Publisher: name: University of British Columbia
Year: 2011

description: Force steadiness (FS) is the ability to maintain a constant isometric contraction around a given force level and is expressed as the coefficient of variation (CV) of force. Although it has recently been shown that men are steadier than women in the elbow flexor muscles, the primary mechanism for this difference has yet to be determined. Motor unit activity is thought to influence FS, in particular motor unit discharge rate variability (MUDRV). The purpose of this thesis was to determine if motor unit activity differs between men and women, and if this is a possible mechanism to explain sex differences in FS. Eight young men (25 ± 3.6 years) and 11 young women (21.2 ± 3.2 years) performed a 7.5 second steady isometric elbow flexion contraction in the neutral wrist position at 5%, 10%, 25% and 50% of maximum voluntary contraction (MVC). Single motor unit activity, force, and surface electromyography (EMG) were measured simultaneously during the 7.5s contraction from the short head (SH) and long head (LH) of the biceps brachii (BB) of the left, non-dominant arm. Results indicate that men were significantly (p < 0.05) stronger than women as well as steadier at all force levels. Motor unit discharge rate (MUDR) and surface EMG did not differ between men and women at the same relative force levels. However, women exhibited greater MUDRV than men (p = 0.02). When data for men and women were combined, significant relationships were observed between CV of force with MVC (r² = 0.42) (p < 0.001), CV of force with MUDR (r² = 0.05) (p = 0.01), but CV of force and MUDRV were not related. When men and women were assessed independently, there was no relationship between FS and MVC, MUDR, or MUDRV for men, yet significant relationships were observed between FS and MVC (r² = 0.35) (p < 0.001) and FS and MUDR (r² = 0.25) (p < 0.001) for women. Partial correlations revealed that maximum strength (-0.71) and MUDR (-0.37) contribute the most to FS. Although MUDRV was greater in women than men during isometric elbow flexion, MUDRV does not appear to be a factor contributing to FS in young adults. Maximum strength seems to be the largest contributor to sex differences in FS, in that the weaker the muscle the less steady it is.
Three-Loop Calculation of the Higgs Boson Mass in Supersymmetry

description: A Key feature of the minimal supersymmetric extension of the Standard Model (MSSM) is the existence of a light Higgs boson, the mass of which is not a free parameter but an observable that can be predicted from the theory. Given that the LHC is able to measure the mass of a light Higgs with very good accuracy, a lot of effort has been put into a precise theoretical prediction. We present a calculation of the SUSY-QCD corrections to this observable to three-loop order. We perform multiple asymptotic expansions in order to deal with the multi-scale three-loop diagrams, making heavy use of computer algebra and keeping a keen eye on the numerical error introduced. We provide a computer code in the form of a Mathematica package that combines our three-loop SUSY-QCD calculation with the literature of one- and two-loop corrections to the Higgs mass, providing a state-of-the-art prediction for this important observable.

description: We predict a quantum phase transition from normal to topological insulators in the 5$d$ transition metal oxide Na$_2$IrO$_3$, where the transition can be driven by the change of the long-range hopping and trigonal crystal field terms. From the first-principles-derived tight-binding Hamiltonian we determine the phase boundary through the parity analysis. In addition, our first-principles calculations for Na$_2$IrO$_3$ model structures show that the interlayer distance can be an important parameter for the existence of a three-dimensional strong topological insulator phase. Na$_2$IrO$_3$ is suggested to be a candidate material which can have both a nontrivial topology of bands and strong electron correlations.

description: We report the discovery of an X-ray/UV stellar flare from the source LMC 335, captured by XMM-Newton in the field of the Large Magellanic Cloud. The flare event was recorded continuously in X-ray for its first 10 hours from the precursor to the late decay phases. The observed fluxes increased by more than two orders of magnitude at its peak in X-ray and at least one in the UV as compared to quiescence. The peak 0.1-7.0 keV X-ray flux is derived from the two-temperature APEC model to be ~(8.4 +/- 0.6) x 10^-12 erg cm-2 s-1. Combining astrometric information from multiple X-ray observations in the quiescent and flare states, we identify the NIR counterpart of LMC 335 as the 2MASS source J05414534-6921512. The NIR color relations and spectroscopic parallax characterize the source as a Galactic K7-M4 dwarf at a foreground distance of (100 - 264) pc, implying a total energy output of the entire event of ~(0.4 - 2.9) x 10^35 erg. This report comprises detailed analyses of this late-K / early-M dwarf flare event that has the longest time coverage yet reported in the literature. The flare decay can be modeled with two exponential components with timescales of ~28 min and ~4 hours, with a single component decay firmly ruled out. The X-ray spectra during flare can be described by two components, a dominant high temperature component of ~40-60MK and a low temperature component of ~10MK, with a flare loop length of about 1.1-1.3 stellar radius.

description: We present an analysis of the WISE photometric data for 829 stars in the Sco-Cen OB2 association, using the latest high-mass membership probabilities. We detect infrared excesses associated with 135 BAF-type stars, 99 of which are secure Sco-Cen members. There is a clear increase in excess fraction with membership probability, which can be fitted linearly. We infer that 41+-5% of Sco-Cen OB2 BAF stars to have excesses, while the field star excess fraction is consistent with zero. This is the first time that the probability of non-membership has been used in the calculation of excess fractions for young stars. We do not observe any significant change in excess fraction between the three subgroups. Within our sample, we have observed that B-type association members have a significantly smaller excess fraction than A and F-type association members.

description: The computational complexity of constructing the imbeddings of a given graph into surfaces of different genus is not well-understood. In this paper, topological methods and a reduction to linear matroid parity are used to develop a polynomial-time algorithm to find a maximum-genus cellular imbedding. This seems to be the first imbedding algorithm for which the running time is not exponential in the genus of the imbedding surface.

description: The titanium alloys are widely used in aeronautical engineering and medical device materials due to exceptional mechanical properties such as tensile resistance and toughness of fractures. High thermo-mechanical loads occur in metal cutting of Titanium alloy Ti6Al4V, which can decrease life of cutting tool and increase cost of part production. In this paper, the coolant effects on the cutting temperature, surface roughness and tool wear are investigated by using the developed virtual machining system. The cutting forces during turning operations of Ti6Al4V alloy are accurately calculated in order to be used in calculation of cutting temperature and tool wear. The modified Johnson-Cook methodology is utilized to obtain the cutting temperatures along machining paths. Then, the Coupled Eulerian-Lagrangian (CEL) approach is investigated to predict and evaluate the effects of coolants on the cutting temperature in turning operations of Ti6Al4V alloy. The finite element approach is employed to predict tool wear by using the Takeyama-Murata analytical model and modifying the cutting tool geometry during the chip production process. To verify the developed methodology in the study, the results of experiments for the measured cutting temperatures, surface quality and wear rate are compared to the results of virtual machining system obtained by the finite element simulation. Thus, utilizing the proposed virtual machining system in the study, cutting temperatures, surface quality and tool wear during the turning operations of Ti6Al4V alloys with and without coolant can be accurately predicted to enhance the accuracy as well as productivity in the CNC machining operations.

description: The magnetic properties of polycrystalline samples of Ba3Cu3In4O12 (In-334) and Ba3Cu3Sc4O12 (Sc-334) are reported. Both 334 phases have a structure derived from perovskite, with CuO4 squares interconnected to form half-twist ladders along the c-axis. The Cu-O-Cu angles, ~ 90o, and the positive Weiss temperatures indicate the presence of significant ferromagnetic (FM) interactions along the Cu ladders. At low temperatures, T < 20 K, sharp transitions in the magnetic susceptibility and heat capacity measurements indicate three-dimensional (3D) antiferromagnetic (AFM) ordering at TN. TN is suppressed on application of a field and a complex magnetic phase diagram with three distinct magnetic regimes below the upper critical field can be inferred from our measurements. The magnetic interactions are discussed in relation to a modified spin-1/2 FM-AFM model and the 334 half-twist ladder is compared to other 2-rung ladder spin-1/2 systems.

description: We present new thermal IR photometry and spectral energy distributions (SEDs) of eight classical Cepheids (type I) and three type II Cepheids, using VISIR thermal IR photometric measurements, supplemented with literature data. We used the BURST mode of the instrument to get diffraction-limited images at 8.59, 11.25 and 11.85 μm. The SEDs show a IR excess at wavelengths longer than 10μm in ten of the eleven stars. We tentatively attribute these excesses to circumstellar emission created by mass loss from the Cepheids. With some hypotheses for the dust composition, we estimated a total mass of the envelope ranging from 10-10 to 10-8 M\odot. We also detect a spatially extended emission around AX Cir, X Sgr, W Sgr, Y Oph and U Car while we do not resolve the circumstellar envelope (CSE) for the other stars. The averaged circumstellar envelope brightnesses relative to the stellar photosphere are α(AX Cir) = 13.8\pm2.5%, α(X Sgr) = 7.9\pm1.4%, α(W Sgr) = 3.8\pm0.6%, α(Y Oph) = 15.1\pm1.4% and α(U Car) = 16.3\pm1.4% at 8.59 μm. With this study, we extend the number of classical Cepheids with detected CSEs from 9 to 14, confirming that at least a large fraction of all Cepheids are experiencing significant mass loss. The presence of these CSEs may also impact the future use of Cepheids as standard candles at near and thermal infrared wavelengths.

Direct utilization of methanol and ethanol in solid oxide fuel cells
Creators: name: Cimenti, Massimiliano
Publisher: name: University of Calgary
Year: 2008

description: Bibliography: p. 423-444
description: Solid oxide fuel cells (SOFC) are high temperature energy conversion devices operating with hydrogen and synthesis gas, but - in principle - they could also utilize hydrocarbons and alcohols. The objective of this study was to investigate the direct utilization of methanol and ethanol in SOFC. Based on the published literature, the following anodic compositions were considered: Me/ceria and Me/zirconia-doped ceria, (Me = Ni, Cu, Co­Co ); L8-0.1Sro.3Cro.sMno.sO3_15 (LSCM); L8-0.1Sro.3 VO3_15 (LSV); and Sro.86 Y o.os TiO3_15 (SYT). In the first part of this thesis, the pyrolysis of methanol and ethanol was examined. It was found that both alcohols undergo significant decomposition, producing mixtures rich in H2, CO and CH4. The conversion depends strongly on the flow and temperature conditions, and is higher for ethanol. The production of soot was always significant for ethanol, while for methanol it became negligible above 800°C. Subsequently, the oxidation of hydrogen and carbon monoxide was investigated on nickel and on the other anode materials using 2 and 3-electrode static and dynamic techniques, combined with impedance spectroscopy measurements. Since distortions affect measurements in 3- electrode planar cells, the configurations used in this study were first validated using a theoretical model. The results obtained indicate that the oxidation of H2 on Ni is about one order of magnitude larger than that of CO. On ceria, LSCM, LSV and SYT, instead, these rates are comparable, but the perovskites alone are very poor electrocatalysts. Besides, a gradual deactivation was observed for LSCM anodes in H2, possibly as a consequence of partial reduction, whereas LSV anodes were very unstable to redox cycling. Finally, the anodes were tested directly with alcohols. The direct utilization of methanol was feasible on all metal/ceria anodes without significant coking. With ethanol metal/ceria anodes were deactivated by coking; however, on Cu/ceria base anodes the deactivation was reversible after exposure to humidified hydrogen, and the anodic microstructure was not damaged. Stability and performance of metal/ceria anodes were improved by using zirconia-doped ceria. The deactivation by coking was delayed by adding small amounts of dispersed ruthenium.
Dynamic Data Structures for Series Parallel Digraphs

description: We consider the problem of dynamically maintaining general series parallel directed acyclic graphs (GSP dags), two-terminal series parallel directed acyclic graphs (TTSP dags) and looped series parallel directed graphs (looped SP digraphs). We present data structures for updating (by both inserting and deleting either a group of edges or vertices) GSP dags, TTSP clags and looped SP digraphs of m edges and n vertices in O( log n) worst-case time. The time required to check whether there is a path between two given vertices is O(log n), while a path of length k can be traced out in O(k + log n) time. For GSP and TTSP dags, our data structures are able to report a regular expression describing all the paths between two vertices x and y in O(h + log n), where h ≤ n is the total number of vertices which are contained in paths from x to y. Although GSP dags can have as many as O(n2) edges, we use an implicit representation which requires only O(n) space. Motivations for studying dynamic graphs arise in several areas, such as communication networks, Incremental compilation environments and the design of very high level languages, while the dynamic maintenance of series parallel graphs is also relevant in reducible flow diagrams.
Conversion : melancholia, masculinity, and psychic change
Creators: name: Semper, Samantha
Publisher: name: University of British Columbia
Year: 2011

description: This study chooses three representations of conversion and asks whether these might challenge or ‘talk back’ to discourse about conversion, or whether they simply transfer a deeply problematic melancholic attachment structure? This analysis considers three primary case studies: the religious conversion of St. Augustine as represented in his Confessions; John Howard Griffin’s white racial conversion narrative, Black Like Me; and the Hip-Hop conversion testimony of Caesar L. Willis, Rude Awakening, and his associated spiritual-autobiographical dance practice of krumping. The first two chapters specifically deal with religious conversion: Chapter One offers a reinterpretation of the role of the maternal and paternal object in religious conversion, and Chapter Two proposes a rereading of the conversion of St. Augustine using this model. The remaining chapters analyze conversion discourse in relation to, and from embedded stances within, the dynamics of racialized oppression and legacy of slavery in the United States of America. The philosopher and psychoanalyst Julia Kristeva carefully distinguishes between “revolt”, from the Latin, revolvere, a productive ‘return’ and ‘rolling’ over of psychic structures, and the conversion, or conversio, turning, of the Christian man. She argues that religious conversion, the turn to religious faith, that ends in “reconciliation” or “unification” is a compromise: “a primary identification with a loving and protective agency” that is compensatory (24). It is a “fusion” with a “nourishing, loving, and protective” “breast” that is “transposed from the mother’s body to an invisible agency located in another world” (24). Building from this, my analysis argues that this compromise is a specifically melancholic compromise marked by the splitting and fusion with the maternal part-object, which is retained in a dynamic of “rejection, yet attachment to”. Because religious conversion is built on a drive toward ‘wholeness’ that is achieved through the fusion with a part-object, it does not represent an ethical relation or productive revolt. However, this analysis asks whether there are examples of conversion that do not end in a melancholic compromise, but instead open up to what Ranjana Khanna calls “critical melancholia” (22).

description: The TTAB surfactant micelle formation in presence of PVA was detected by the evaluation of CMC from the conductivity plot against the concentration of surfactant. Micellar parameters, such as critical micelle concentration (CMC), the extent of counter ion binding (β), and thermodynamic properties (ΔG0m, ΔH0m and ΔS0m) of PVA + TTAB systems have been estimated. Values of CMC of the PVA + TTAB mixed system was achieved and found to reduce with enhancing PVA concentrations which designate the survival of interactions between TTAB and PVA. The values of CMC were found to undergo an increase in the mixed solvents in comparison to the values obtained in aqueous media, which might be attributed to the reduction of the dielectric constant as well as water cohesive energy. The values of free energy of micellisation (ΔGmo) are negative for the PVA + TTAB system, suggesting a spontaneous aggregation phenomenon. The negative values of ΔGmo in H2O and 9% (w/w) mixed solvents follow the order: ΔGmo (H2O) > ΔGmo (water + AN) > ΔGmo (water + DO) >ΔGmo (water + DMF). The thermodynamic properties of transfer were also estimated for the move of PVA+ TTAB mixed system from water to aqua-organic mixture of solvents.

description: Monte Carlo and molecular dynamics simulations were performed for the adsorption-diffusion properties of dimethyl ether (DME) and carbon monoxide (CO) pure gas and mixture with different feed ratio in H-MOR zeolite to find out the influence of feed ratio on the DME carbonylation activity. For pure gas, DME adsorbs stronger than CO with a competitive adsorption, and all molecules have relatively good diffusion properties. For the mixture, in low feed ratio (PCO/PDME = 1–10), the adsorption capacity of CO in 8-MR cannot meet the reaction requirement caused the low carbonylation activity, while increasing the feed ratio (to PCO/PDME = 20–30) will promote CO adsorption. The optimal feed ratio PCO/PDME ≈ 27:1 is also discovered. Furthermore, it can also reduce the total molecular per cell and improve the diffusion in each channel which is another factor for the carbonylation activity improvement. Highlights:The adsorption ratio of NCO/NDME in H-MOR was investigated from both adsorption and diffusion sides, which is the key factor affecting the activity of DME carbonylation.A new scheme was proposed to optimise the carbonylation activity by changing the feed ratio, and the mechanism of increase and decrease of feed ratio was analysed from a microscopic point of view.The optimal feed ratio PCO/PDME ≈ 27:1 for DME carbonylation in H-MOR was discovered.A wide range of experimental feed ratio data (covers PCO/PDME = 1:1 to PCO/PDME = 1:50), so this research work provides a new idea for the next subsequent modification of H-MOR, which is to reduce the optimal feed ratio to an acceptable level.

description: In a recent paper, we analyzed the self-assembly of a complex cooperation network. The network was shown to approach a state where every agent invests the same amount of resources. Nevertheless, highly-connected agents arise that extract extraordinarily high payoffs while contributing comparably little to any of their cooperations. Here, we investigate a variant of the model, in which highly-connected agents have access to additional resources. We study analytically and numerically whether these resources are invested in existing collaborations, leading to a fairer load distribution, or in establishing new collaborations, leading to an even less fair distribution of loads and payoffs.

description: The administrative control of the Nāik Pratāp Rāu Sardesāi family extended over most of the present central and south Goa, “and for considerable periods of time beyond the mountains over the region of Belgaum and Dharwar.” What is meant by ‘central and south Goa’ here is the territory to the south and to the east of the Tisvāḍi mahāl. Tisvāḍi mahāl was not a part of any watandārī, being administered directly by the king, as it was a port region. As for the antiquity of this watandārī, we can safely assume that it prevailed during the Bijapuri rule and during the Vijayanagar rule before that, as we shall soon see. But, if we are to go by Vaman Narhar Sardesai’s Mavalankar Gharanyacha Itihas, the family title of sardesāi as such can be traced to theŚilāhār times. Does the history of this sardesāi too go back to the Śilāhār times ?

description: Orientation influences the severity of the exposure to which walls are subjected. Temperatures at any given time can vary as much as 90 degrees due to solar radiation; and the number of freeze-thaw cycles can subsequently be increased as the result of solar radiation. Wetting of walls, as influenced by prevailing winds and air leakage patterns, is also of significance with respect to the environment in which materials must serve.
Finite Size Scaling for the Glass Transition: the Role of a Static Length Scale

description: Over the last decade computer simulations have had an increasing role in shedding light on difficult statistical physical phenomena and in particular on the ubiquitous problem of the glass transition. Here in a wide variety of materials the viscosity of a super-cooled liquid increases by many orders of magnitude upon decreasing the temperature over a modest range. A natural concern in these computer simulation is the very small size of the simulated systems compared to experimental ones, raising the issue of how to assess the thermodynamic limit. Here we offer a theory for the glass transition based on finite size scaling, a method that was found very useful in the context of critical phenomena and other interesting problems. As is known, the construction of such a theory rests crucially on the existence of a growing {\em static} length scale upon decreasing the temperature. We demonstrate that the static length scale that was discovered in Ref. \cite{12KLP} fits the bill extremely well, allowing us to provide a finite size scaling theory for the $α$ relaxation time of the glass transition, including predictions for the thermodynamic limit based on simulations in small systems.

description: The high cost of operating large computing installations has motivated a broad interest in reducing the need for human intervention by making systems self-managing. This paper explores the extent to which control theory can provide an architectural and analytic foundation for building self-managing systems. Control theory provides a rich set of methodologies for building automated self-diagnosis and self-repairing systems with properties such as stability, short settling times, and accurate regulation. However, there are challenges in applying control theory to computing systems, such as developing effective resource models, handling sensor delays, and addressing lead times in effector actions. We propose a deployable testbed for autonomic computing (DTAC) that we believe will reduce the barriers to addressing research problems in applying control theory to computing systems. The initial DTAC architecture is described along with several problems that it can be used to investigate.

The internet and empowerment: a study on women internet users in Bangladesh
Creators: name: Choudhury, Naziat
Publisher: name: University of Calgary
Year: 2008

description: Bibliography: p. 114-121
description: This study poses the question of whether and under what conditions the Internet was or was not an empowering tool for women Internet users in Bangladesh. Hence, the focus is on home-based female Internet users. The main thrust of the study was on those women who were not associated with technology, academically or professionally. In other words, my target people were plain and simple home-based women Internet users. The study is based on the domestication of technology theory and on the concept of empowerment in terms of agency. In-depth interviews were conducted among sixteen participants from two different cities in Bangladesh. The aim of the research was to attain information on women's use of the Internet, what they understood by empowerment and if their use of the Internet contributed in any way to their empowerment. The data show that compared to men, women are late on joining the Internet phenomenon in Bangladesh. The study also shows that women are using the Internet for many interesting purposes. Similar to other developing countries, this study has found that the respondents belong to middle and upper-middle class families with higher levels of education. According to their definition of empowerment, women respondents believe that their use of the Internet is bringing empowerment to them. In a male dominated society, this is definitely a significant move forward.
L’image de l’Asie Mineure et des Turcs dans les textes narratifs du Moyen Âge français (XIIe-milieu du XVe siècle)
Creators: name: Lushchenko, Marina
Publisher: name: University of British Columbia
Year: 2011

description: This study explores the medieval French perceptions of Turkish Asia Minor and the Turks in the time period between 1096 and 1453. Unlike medieval representations of other Eastern nations, very little research has been done on those of the Turks. Focusing on a variety of medieval French texts within a variety of genres, this research argues that the collective perception of the Turks results from medieval authors’ subjective interpretations, based more on cultural values and ideologies of European feudal society, memories of classical Antiquity and Christian traditions than on factual reality. Using as a point of reference the cultural approach and the works of Edward S. Said, Jacques Le Goff and Georges Duby, it is shown that the Turkish ‘Other’ is pre-eminently a product of Western imagination. The first chapter centres on the ambivalence of medieval geographical descriptions of Asia Minor, in which its portrayal as a land of evil blends with reminiscences of the classical and Christian past. The second chapter investigates the medieval French conceptions of the Turks’ origins, identity and history through the prism of literary traditions, historiographical considerations and political factors. The third chapter concentrates on the formation and various uses of the enemy image of the Turk in the medieval West. The last chapter shows how conformity or non-conformity of Turkish cultural practices to the system of Western feudal values influenced the genesis of negative but also positive perceptions of the Turks in the medieval West.

description: A new fluorescent probe HSL-AI derived from imidazo [1,5- a]pyridine was synthesised for the detection of hydrazine (N2H4) based on excited-state intramolecular proton transfer (ESIPT). HSL-AI was designed using acetyl group as the recognition site and exhibited high selectivity towards N2H4 with a low limit of detection (2.56 ppb). Moreover, HSL-AI was successfully applied to detect N2H4 in living cells.

description: Event correlation is essential to realizing self-managing distributed systems. For example, distributed systems often require that events be correlated from multiple systems using temporal patterns to detect denial of service attacks and to warn of problems with business critical applications that run on multiple servers. This paper addresses how to specify timer values for temporal patterns so as to manage the trade-off between false alarms and undetected alarms. A central concern is addressing the variability of event propagation delays due to factors such as contention for network and server resources. To this end, we develop an architecture and an adaptive control algorithm that dynamically compensate for variations in propagation delays. Our approach makes Management Stations more autonomic by avoiding the need for manual adjustments of timer values in temporal rules. Further, studies we conducted of a testbed system suggest that our approach produces results that are at least as good as an optimal fixed setting of timer values.

description: We review recent studies of coherent phonons (CPs) corresponding to the radial breathing mode (RBM) and G-mode in single-wall carbon nanotubes (SWCNTs) and graphene. Because of the bandgap-diameter relationship, RBM-CPs cause bandgap oscillations in SWCNTs, modulating interband transitions at terahertz frequencies. Interband resonances enhance CP signals, allowing for chirality determination. Using pulse shaping, one can selectively excite speci!c-chirality SWCNTs within an ensemble. G-mode CPs exhibit temperature-dependent dephasing via interaction with RBM phonons. Our microscopic theory derives a driven oscillator equation with a density-dependent driving term, which correctly predicts CP trends within and between (2n+m) families. We also find that the diameter can initially increase or decrease. Finally, we theoretically study the radial breathing like mode in graphene nanoribbons. For excitation near the absorption edge, the driving term is much larger for zigzag nanoribbons. We also explain how the armchair nanoribbon width changes in response to laser excitation.

description: The relativistic six-quark equations are constructed in the framework of the dispersion relation technique. The relativistic six-quark amplitudes of dibaryons including the light $u$, $d$ and heavy $c$, $b$ quarks are calculated. The approximate solutions of these equations using the method based on the extraction of leading singularities of the heavy hexaquark amplitudes are obtained. The poles of these amplitudes determine the masses of charmed and bottom dibaryons with the isospins I=0, 1, 2 and the spin-parities $J^P=0^+$, $1^+$, $2^+$.
