Nature inspired artificial intelligence based adaptive traffic flow distribution in computer network
Creators: name: Singh, Manoj Kumar
Publisher: name: arXiv
Year: 2010
Subjects: subject: Neural and Evolutionary Computing (cs.NE)
subject: FOS: Computer and information sciences

description: Because of the stochastic nature of traffic requirement matrix, it is very difficult to get the optimal traffic distribution to minimize the delay even with adaptive routing protocol in a fixed connection network where capacity already defined for each link. Hence there is a requirement to define such a method, which could generate the optimal solution very quickly and efficiently. This paper presenting a new concept to provide the adaptive optimal traffic distribution for dynamic condition of traffic matrix using nature based intelligence methods. With the defined load and fixed capacity of links, average delay for packet has minimized with various variations of evolutionary programming and particle swarm optimization. Comparative study has given over their performance in terms of converging speed. Universal approximation capability, the key feature of feed forward neural network has applied to predict the flow distribution on each link to minimize the average delay for a total load available at present on the network. For any variation in the total load, the new flow distribution can be generated by neural network immediately, which could generate minimum delay in the network. With the inclusion of this information, performance of routing protocol will be improved very much.

description: Eesmärk. Analüüsida arstiabi, teatud ravimite kasutamise ja vähi varase avastamise uuringute tegemise piirkondlikke erinevusi Eestis.  Metoodika. Analüüsiks kasutati Eesti täiskasvanud rahvastiku tervisekäitumise uuringu 2012 andmeid. Uuringu tegemiseks telliti rahvastikuregistrist kihitatud juhuvalim, millesse kuulus 5000 isikut vanuses 16–64 aastat. Küsimustikud koostati nii eesti kui ka vene keeles. Postiküsitlus toimus märtsis-aprillis 2012, sellele vastas 2969 isikut. Piirkondlike erinevuste hindamiseks jagati Eesti 5-ks ning tulemusi väljendati võrdluses Põhja-Eesti näitajatega mitmese logistilise regressiooni abil. Šansisuhted koos 95% usaldusvahemikuga arvutati kohandatuna soole, vanusele, haridusele, sissetulekule ja majanduslikule aktiivsusele.  Tulemused. Võrdluses Põhja-Eestiga oli oluliselt suurem viimase 12 kuu jooksul perearstiabi kasutamine Lõuna-Eestis, perearstiabi kasutanute visiitide keskmine arv kõigis Eesti piirkondades; haiglaravil viibimine, vastamisele eelnenud viimase seitsme päeva jooksul mitmete ravimite kasutamine ning naistel viimase viie aasta jooksul Pap-testi mittetegemine Kirde-Eestis; oluliselt väiksem oli rahustite/uinutite/antidepressantide kasutamine Kesk- ja Lääne-Eestis ning Pap-testi mittetegemine Lõuna-Eestis.  Kokkuvõte. Ainult Kirde-Eestis esines olulisi erinevusi võrreldes Põhja-Eestiga kõigis uuritud valdkondades. Valdavalt riikliku sõeluuringu raames tehtava mammogrammi mittetegemisel olulisi piirkondlikke erinevusi ei ilmnenud. Tõenäoliselt on leitud erinevuste põhjustes oma osa ka tervishoiukorralduse piirkondlikel erinevustel.Eesti Arst 2013; 92(10):557–563

description: We present a new efficient method for Monte Carlo simulations of diffusion-reaction processes. First introduced by us in [Phys. Rev. Lett., 97:230602, 2006], the new algorithm skips the traditional small diffusion hops and propagates the diffusing particles over long distances through a sequence of super-hops, one particle at a time. By partitioning the simulation space into non-overlapping protecting domains each containing only one or two particles, the algorithm factorizes the N-body problem of collisions among multiple Brownian particles into a set of much simpler single-body and two-body problems. Efficient propagation of particles inside their protective domains is enabled through the use of time-dependent Green's functions (propagators) obtained as solutions for the first-passage statistics of random walks. The resulting Monte Carlo algorithm is event-driven and asynchronous; each Brownian particle propagates inside its own protective domain and on its own time clock. The algorithm reproduces the statistics of the underlying Monte-Carlo model exactly. Extensive numerical examples demonstrate that for an important class of diffusion-reaction models the new algorithm is efficient at low particle densities, where other existing algorithms slow down severely.

description: We have developed a dynamical model for a unified description of the pion-nucleus scattering and photo- and neutrino-induced coherent pion production on nuclei. Our approach is based on a combined use of the Sato-Lee model for the electroweak pion production on a single nucleon and the Delta-hole model of pion-nucleus scattering. Numerical calculations are carried out for the case of the C12 target. After testing our model with the use of the pion photo-production data, we confront our predictions of the neutrino-induced coherent pion production reactions with the recent data from K2K and MiniBooNE.

Geology and petrogenesis of the Serb Creek intrusive complex near Smithers, British Columbia
Creators: name: Sellmer, H. W.
Publisher: name: University of British Columbia
Year: 2011

description: The Serb Creek molybdenite property is 26 miles west-northwest of Smithers, B. C. on the northeast flank of the Howson Range of the Coast Range physiographic province. The property lies within an upper mesozonal to lower epizonal batholithic offshoot of the Coast Range Intrusive Complex. Small irregular plutons and a series of northwesterly-striking dykes intrude the batholith. The rocks are quartz monzonitic and, in texture range from coarse-grained granitic to porphyritic. Plots of optic angle against composition show that feldspars are of intermediate structural type indicating an increasingly rapid rate of cooling from the oldest to the youngest intrusive body. This increase in the rate of cooling is ascribed to smaller size of intrusive body with decreasing age. Plots of normative Q:AbOr ratios suggest that, if one believes the magma to have formed by anatexis, high pressures of volatiles, HC1, or of both were present during crystallization. Two general attitudes—N20° W to N^5°w and N75° E--control the emplacement of intrusive bodies, hydrothermal alteration, and, to a large extent, molybdenite mineralization. Hydrothermal alteration and molybdenite mineralization appear to be related to igneous activity because they are closely associated in time and space.

description: We study the Quantum Regge Calculus of Einstein-Cartan theory to describe quantum dynamics of Euclidean space-time discretized as a 4-simplices complex. Tetrad field e_μ(x) and spin-connection field ω_μ(x) are assigned to each 1-simplex. Applying the torsion-free Cartan structure equation to each 2-simplex, we discuss parallel transports and construct a diffeomorphism and {\it local} gauge-invariant Einstein-Cartan action. Invariant holonomies of tetrad and spin-connection fields along large loops are also given. Quantization is defined by a bounded partition function with the measure of SO(4)-group valued ω_μ(x) fields and Dirac-matrix valued e_μ(x) fields over 4-simplices complex.

Kõige sagedasemaks mädase meningiidi tekitajaks oli S. pneumoniae ja pneumokokiline meningiit oli ka sagedasimaks surma põhjuseks. Empiirilist ravi alustati enamikul juhtudest penitsilliini ja gentamütsiini kombinatsiooniga. Haigus lõppes surmaga 28 juhul, täielikult paranes 48 patsienti ja ülejäänutel esines haiglast lahkumisel neuroloogiline häire. Bakteriaalse meningiidiga haigete prognoos on halvem, kui Glasgow’ koomaskaala skoor hospitaliseerimisel on väike. Prognoosi halvendab patsientide vanem iga ja pneumokokiline infektsioon.

description: Non-dominated Sorting Genetic Algorithm (NSGA) has established itself as a benchmark algorithm for Multiobjective Optimization. The determination of pareto-optimal solutions is the key to its success. However the basic algorithm suffers from a high order of complexity, which renders it less useful for practical applications. Among the variants of NSGA, several attempts have been made to reduce the complexity. Though successful in reducing the runtime complexity, there is scope for further improvements, especially considering that the populations involved are frequently of large size. We propose a variant which reduces the run-time complexity using the simple principle of space-time trade-off. The improved algorithm is applied to the problem of classifying types of leukemia based on microarray data. Results of comparative tests are presented showing that the improved algorithm performs well on large populations.

description: We show how to get a non-commutative product for functions on space-time starting from the deformation of the coproduct of the Poincare' group using the Drinfel'd twist. Thus it is easy to see that the commutative algebra of functions on space-time (R^4) can be identified as the set of functions on the Poincare' group invariant under the right action of the Lorentz group provided we use the standard coproduct for the Poincare' group. We obtain our results for the noncommutative Moyal plane by generalizing this result to the case of the twisted coproduct. This extension is not trivial and involves cohomological features. As is known, spacetime algebra fixes the coproduct on the dffeomorphism group of the manifold. We now see that the influence is reciprocal: they are strongly tied.

description: We develop an asynchronous event-driven First-Passage Kinetic Monte Carlo (FPKMC) algorithm for continuous time and space systems involving multiple diffusing and reacting species of spherical particles in two and three dimensions. The FPKMC algorithm presented here is based on the method introduced in [Phys. Rev. Lett., 97:230602, 2006] and is implemented in a robust and flexible framework. Unlike standard KMC algorithms such as the n-fold algorithm, FPKMC is most efficient at low densities where it replaces the many small hops needed for reactants to find each other with large first-passage hops sampled from exact time-dependent Green's functions, without sacrificing accuracy. We describe in detail the key components of the algorithm, including the event-loop and the sampling of first-passage probability distributions, and demonstrate the accuracy of the new method. We apply the FPKMC algorithm to the challenging problem of simulation of long-term irradiation of metals, relevant to the performance and aging of nuclear materials in current and future nuclear power plants. The problem of radiation damage spans many decades of time-scales, from picosecond spikes caused by primary cascades, to years of slow damage annealing and microstructure evolution. Our implementation of the FPKMC algorithm has been able to simulate the irradiation of a metal sample for durations that are orders of magnitude longer than any previous simulations using the standard Object KMC or more recent asynchronous algorithms.

Energy Spectra from Electromagnetic Fields Generated by Ultra-relativistic Charged Bunches in a Perfectly Conducting Cylindrical Beam Pipe

Year: 2009
Subjects: subject: Accelerator Physics (physics.acc-ph)

description: The spectrum of electromagnetic fields satisfying perfectly conducting boundary conditions in a segment of a straight beam pipe with a circular cross-section is discussed as a function of various source models. These include charged bunches that move along the axis of the pipe with constant speed for which an exact solution to the initial-boundary value problem for Maxwell's equations in the beam pipe is derived. In the ultra-relativistic limit all longitudinal components of the fields tend to zero and the spectral content of the transverse fields and average total electromagnetic energy crossing any section of the beam pipe are directly related to the properties of the ultra-relativistic source. It is shown that for axially symmetric ultra-relativistic bunches interference effects occur that show a striking resemblance to those that occur due to CSR in cyclic machines despite the fact that in this limit the source is no longer accelerating. The results offer an analytic description showing how such enhanced spectral behaviour depends on the geometry of the source and the details of the stochastic distribution of structure within the source. They offer a viable experimental means for inferring properties of the longitudinal charge distribution of bunches with micro-structure in ultra-relativistic motion in straight segments of a beam pipe from observation of the associated electromagnetic energy spectra. They are also of relevance to design criteria where the coherence effects of such fields play a significant role.

Palynology of Tertiary rocks of the Whatcom Basin, Southwestern British Columbia and Northwestern Washington.
Creators: name: Hopkins, William Stephen
Publisher: name: University of British Columbia
Year: 2011

description: Lower and Middle Tertiary continental sedimentary rocks comprise the fill in a large structural basin adjacent to the Georgia Depression in southwestern British Columbia and northwestern Washington. Upper Cretaceous continental sedimentary rocks apparently underlie the entire basin. Outcrops of Tertiary rocks are restricted to the north, south and east margins where they are dipping into the basin and overlying older rocks rimming the basin. Relationships to the west are obscured by the Strait of Georgia, but apparently the Whatcom basin is part of, and contiguous with, the Georgia depression. Over most of the area, surface cover is Pleistocene and Recent sediments. Investigations of plant microfossils from two deep basin wells indicate three distinct floras in pre-Pleistocene rocks. Basal portions contain a relatively small Upper Cretaceous floral assemblage. Above this are Middle and probably Upper Eocene assemblages. Upper parts of the section contain a predominantly dicotyledonous Miocene assemblage. Palynological study of the outcrops indicates a Middle to Upper Eocene age for all except the Brothers Creek outcrop on the north side of Burrard Inlet, which appears to be Upper Cretaceous. Miocene rocks are found only in the wells, and apparently do not crop out. Eocene assemblages contain Pistillipollenites and Platycarya together with significant numbers of Cactricosisporites and Anemia spores, and suggest a warm temperate to subtropical climate. Miocene assemblages are generally characterized by Glyptostrobus, Pterocarya, Ulmus-Zelkoya and Fagus and several other dicotyledonous pollen. Miocene assemblages indicate a more temperate aspect than those of the Eocene.

description: Separation of the text regions from background texture and graphics is an important step of any optical character recognition system for the images containing both texts and graphics. In this paper, we have presented a novel text/graphics separation technique and a method for skew correction of text regions extracted from business card images captured with a cell-phone camera. At first, the background is eliminated at a coarse level based on intensity variance. This makes the foreground components distinct from each other. Then the non-text components are removed using various characteristic features of text and graphics. Finally, the text regions are skew corrected for further processing. Experimenting with business card images of various resolutions, we have found an optimum performance of 98.25% (recall) with 0.75 MP images, that takes 0.17 seconds processing time and 1.1 MB peak memory on a moderately powerful computer (DualCore 1.73 GHz Processor, 1 GB RAM, 1 MB L2 Cache). The developed technique is computationally efficient and consumes low memory so as to be applicable on mobile devices.

description: OBJECTIVE: To evaluate whether sedentary time (ST) and/or sedentary behavior patterns are related to incident diabetes in the U.S.'s oldest age-groups. RESEARCH DESIGN AND METHODS: Women without physician-diagnosed diabetes (n = 4,839, mean ± SD age = 79 ± 7 years) wore accelerometers for ≥4 days and were followed up to 6 years for self-reported newly diagnosed diabetes requiring treatment with medications. Hazard ratios (HRs) for incident diabetes were estimated across quartiles of accelerometer-measured ST and mean bout duration with use of Cox proportional hazards models. We conducted isotemporal substitution analyses using Cox regression and tested associations with risk for diabetes after statistically replacing ST with light physical activity (PA) or moderate-to-vigorous PA (MVPA) and after replacing light PA with MVPA. RESULTS: During 20,949 person-years, 342 diabetes cases were identified. Women in ST quartile (Q)2, Q3, and Q4 (vs. Q1) had incident diabetes HR 1.20 (95% CI 0.87-1.65), 1.33 (0.97-1.82), and 1.21 (0.86-1.70); Ptrend = 0.04. Respective HRs following additional adjustment for BMI and MVPA were 1.04 (95% CI 0.74-1.47), 1.04 (0.72-1.50), and 0.85 (0.56-1.29); Ptrend = 0.90. Fully adjusted isotemporal substitution results indicated that each 30 min of ST replaced with MVPA (but not light PA) was associated with 15% lower risk for diabetes (HR 0.85 [95% CI 0.75-0.96]; P = 0.01); the HR for replacing 30 min of light PA with MVPA was 0.85 (95% CI 0.73-0.98); P = 0.03. Mean bout duration was not associated with incident diabetes. CONCLUSIONS: Statistically replacing ST or light PA with MVPA was associated with lower diabetes risk in older women. While reducing ST is important for several health outcomes, results indicate that to reduce diabetes risk among older adults, the primary public health focus should be on increasing MVPA.

description: The resistance of chemically synthesized polypyrrole (PPy) thin films is investigated as a function of the pressure of various gases as well as of the film thickness. A physical, piezoresistive response is found to coexist with a chemical response if the gas is chemically active, like, e.g., oxygen. The piezoresistance is studied separately by exposing the films to the chemically inert gases such as nitrogen and argon. We observe that the character of the piezoresistive response is a function not only of the film thickness, but also of the pressure. Films of a thickness below 70 nm show a decreasing resistance as pressure is applied, while for thicker films, the piezoresistance is positive. Moreover, in some films of thickness of about 70 nm, the piezoresistive response changes from negative to positive as the gas pressure is increased above 500 mbars. This behavior is interpreted in terms of a total piezoresistance which is composed of a surface and a bulk component, each of which contributes in a characteristic way. These results suggest that in polypyrrole, chemical sensing and piezoresistivity can coexist, which needs to be kept in mind when interpreting resistive responses of such sensors.

description: Physical and social environments of parks and neighborhoods influence park use, but the extent of their relative influence remains unclear. This cross-sectional study examined the relationship between the physical and social environment of parks and both observed and self-reported park use in low-income neighborhoods in New York City. We conducted community- (n = 54 parks) and individual-level (n = 904 residents) analyses. At the community level, observed park use was measured using a validated park audit tool and regressed on the number of facilities and programmed activities in parks, violent crime, stop-and-frisk incidents, and traffic accidents. At the individual level, self-reported park use was regressed on perceived park quality, crime, traffic-related walkability, park use by others, and social cohesion and trust. Data were collected in 2016–2018 and analyzed in 2019–2020. At the community level, observed park use was negatively associated with stop-and-frisk (β = −0.04; SE = 0.02; p < 0.05) and positively associated with the number of park facilities (β = 1.46; SE = 0.57; p < 0.05) and events (β = 0.16; SE = 0.16; p < 0.01). At the individual level, self-reported park use was positively associated with the social cohesion and trust scale (β = 0.02; SE = 0.01; p < 0.05). These results indicate that physical and social attributes of parks, but not perceptions of parks, were significantly associated with park use. The social environment of neighborhoods at both community and individual levels was significantly related to park use. Policies for increasing park use should focus on improving the social environment of parks and surrounding communities, not only parks' physical attributes. These findings can inform urban planning and public health interventions aimed at improving the well-being of residents in low-income communities.

description: Longitudinal, natural experiments provide an ideal evaluation approach to better understand the impact of built environment interventions on community health outcomes, particularly health disparities. As there are many participant engagement challenges inherent in the design of large-scale community-based studies, adaptive and iterative participant engagement strategies are critical. This paper shares practical lessons learned from the Physical Activity and Redesigned Community Spaces (PARCS) study, which is an evaluation of the impact of a citywide park renovation initiative on physical activity, psychosocial health, and community well-being. The PARCS study, although ongoing, has developed several approaches to improve participant engagement: building trust with communities, adapting the study protocol to meet participants’ needs and to reflect their capacity for participation, operational flexibility, and developing tracking systems. These strategies may help researchers anticipate and respond to participant engagement challenges in community-based studies, particularly in low-income communities of color.

description: Background: Self-reported time spent standing has been associated with lower risk of mortality. No previous studies have examined this association using device-measured standing. Method: This was a prospective cohort study of 5878 older (median age = 80 years), racial/ethnically diverse, community-dwelling women in the WHI Objective Physical Activity and Cardiovascular Health Study (OPACH). Women wore accelerometers for 1 week and were followed for mortality. The study applied previously validated machine learning algorithms to ActiGraph GT3X+ accelerometer data to separately measure time spent standing with and without ambulation. Cox proportional hazards models were used to estimate mortality risk adjusting for potential confounders. Effect modification by age, body mass index, moderate-to-vigorous physical activity, sedentary time, physical functioning, and race/ethnicity was evaluated. Results: There were 691 deaths during 26 649 person-years of follow-up through March 31, 2018 (mean follow-up = 4.8 years). In fully adjusted models, all-cause mortality risk was lower among those with more standing without ambulation (quartile [Q] 4 vs Q1 HR = 0.63; 95% CI = 0.49-0.81, p-trend =.003) and more standing with ambulation (Q4 vs Q1 HR = 0.50; 95% CI = 0.35-0.71, p-trend <.001). Associations of standing with ambulation and mortality were stronger among women with above-median sedentary time (HR = 0.51; 95% CI = 0.38-0.68) compared to women with below-median sedentary time (HR = 0.80; 95% CI = 0.59-1.07; p-interaction =.02). Conclusions: In this prospective study among older women, higher levels of accelerometer-measured standing were associated with lower risks of all-cause mortality. Standing is an achievable approach to interrupting prolonged sedentary time, and if not contraindicated, is a safe and feasible behavior that appears to benefit health in older ages.

description: Three-body systems with large scattering length display universal phenomena associated with a discrete scaling symmetry. These phenomena include resonant enhancement of three-body loss rates when an Efimov three-body resonance is at the scattering threshold. In particular, there can be resonant peaks in the atom-dimer relaxation rate for large positive scattering length. We improve upon earlier studies and calculate the atom-dimer relaxation rate as a function of temperature using a Bose-Einstein distribution for the thermal average. As input, we use calculations of the atom-dimer scattering phase shifts from effective field theory.

description: SU(N) gauge theories, extended with adjoint fermions having periodic boundary conditions, are confining at high temperature for sufficiently light fermion mass $m$. In the high temperature confining region, the one-loop effective potential for Polyakov loops has a Z(N)-symmetric confining minimum. String tensions associated with Polyakov loops are calculable in perturbation theory, and display a novel scaling behavior in which higher representations have smaller string tensions than the fundamental representation. In the magnetic sector, the Polyakov loop plays a role similar to a Higgs field, leading to an apparent breaking of SU(N) to $U(1)^{N-1}$. This is turn yields a dual effective theory where magnetic monopoles give rise to string tensions for spatial Wilson loops. The spatial string tensions are calculable semiclassically from kink solutions of the dual system. We show that the spatial string tensions $σ^{(s)}_k$ associated with each $N$-ality $k$ obey a variant of Casimir scaling $σ^{(s)}_k /σ^{(s)}_1 \leq \sqrt{k(N-k)/(N-1)} $. Although lattice simulations indicate that the high temperature confining region is smoothly connected to the confining region of low-temperature pure SU(N) gauge theory, the electric and magnetic string tension scaling laws are different and readily distinguishable.

description: Objective The cross-sectional association between accelerometer-measured physical activity (PA), sedentary behaviour (SB) and cardiac structure and function is less well described. This study's primary aim was to compare echocardiographic measures of cardiac structure and function with accelerometer measured PA and SB. Methods Participants included 1206 self-identified Hispanic/Latino men and women, age 45-74 years, from the Echocardiographic Study of Latinos. Standard echocardiographic measures included M-mode, two-dimensional, spectral, tissue Doppler and myocardial strain. Participants wore an Actical accelerometer at the hip for 1 week. Results The mean±SE age for the cohort was 56±0.4 years, 57% were women. Average moderate to vigorous PA (MVPA) was 21±1.1 min/day, light PA was 217±4.2 min/day and SB was 737±8.1 min/day. Both higher levels of light PA and MVPA (min/day) were associated with lower left ventricular (LV) mass index (LVMI)/end-diastolic volume and a lower E/e′ ratio. Higher levels of MVPA (min/day) were associated with better right ventricular systolic function. Higher levels of SB were associated with increased LVMI. In a multivariable linear regression model adjusted for demographics and cardiovascular disease modifiable factors, every 10 additional min/day of light PA was associated with a 0.03 mL/m 2 increase in left atrial volume index (LAVI) (p<0.01) and a 0.004 cm increase in tricuspid annular plane systolic excursion (p<0.01); every 10 additional min/day of MVPA was associated with a 0.18 mL/m 2 increase in LAVI (p<0.01) and a 0.24% improvement in global circumferential strain (p<0.01). Conclusions Our findings highlight the potential positive association between the MVPA and light PA on cardiac structure and function.

description: We present a theoretical study for adhesion-induced lateral phase separation for a membrane with short stickers, long stickers and repellers confined between two hard walls. The effects of confinement and repellers on lateral phase separation are investigated. We find that the critical potential depth of the stickers for lateral phase separation increases as the distance between the hard walls decreases. This suggests confinement-induced or force-induced mixing of stickers. We also find that stiff repellers tend to enhance, while soft repellers tend to suppress adhesion-induced lateral phase separation.

description: India is a multi-lingual country where Roman script is often used alongside different Indic scripts in a text document. To develop a script specific handwritten Optical Character Recognition (OCR) system, it is therefore necessary to identify the scripts of handwritten text correctly. In this paper, we present a system, which automatically separates the scripts of handwritten words from a document, written in Bangla or Devanagri mixed with Roman scripts. In this script separation technique, we first, extract the text lines and words from document pages using a script independent Neighboring Component Analysis technique. Then we have designed a Multi Layer Perceptron (MLP) based classifier for script separation, trained with 8 different wordlevel holistic features. Two equal sized datasets, one with Bangla and Roman scripts and the other with Devanagri and Roman scripts, are prepared for the system evaluation. On respective independent text samples, word-level script identification accuracies of 99.29% and 98.43% are achieved.
