Maximizing the Capacity of Edge-Caching Networks With User-Content Evolution Relationship

System capacity is an important metric for evaluating the performance of edge-caching networks. In most previous studies, the caching content was assumed to remain unchanged in a base station. Hence, the requested probability for each content was treated as stable; In fact, both the number of content and users can change overtime, which impacts the system performance. This article firstly constructs a new user-content evolution model to infer such performance changes, and analyzes the number of links between users and content (i.e., degree). Then, the requested probability of the content and the optimal copy number are calculated by using the content degree. Next, the minimum average transmission distance of the content and system capacity under the cache scheme are given. Finally, a user-content time-varying system is simulated. The results show that the proposed model can characterize the evolution relationship between users and content and achieve better performance in terms of system capacity.
Macroﬁnancial Feedback, Bank Stress Testing and Capital Surcharges

We develop a framework to assess macroﬁnancial vulnerabilities across the business and ﬁnancial cycles, and to calibrate a countercyclical capital buﬀer (CCyB) to account for those vulnerabilities in the context of bank stress tests. A parsimonious model captures the dynamic relationship between bank capital, ﬁnancial conditions, and GDP growth, quantiﬁes the causal impact of shocks to bank capital on the future distribution of ﬁnancial conditions and future downside risks to GDP growth, and estimates macroﬁnancial feedback eﬀects. Our model calibrates a bank capital surcharge, the additional bank capital that accounts for the macroﬁnancial feedback— typically overlooked in bank stress tests—as a macroprudential tool to avert banks’ ampliﬁcation of shocks to the economy. Using a Growth-at-Risk based metric as a measure of ﬁnancial stability risks, we calibrate the size and the timing of the CCyB, as the capital needed to oﬀset the macroﬁnancial feedback across the business cycle.
Influence Of Abiotic Variables On The Bat Fauna Of A Granitic Cave And Its Surroundings In The State Of São Paulo, Brazil

In the present study we analyzed the bat assemblage of the granitic cave Gruta do Riacho Subterrâneo and its surroundings (Itu, Sao Paulo state, Brazil) aiming to verify the influence of seasonality on its species composition and population abundances. Five samplings were carried out with three days of duration each, along the period from October 2013 to September 2014. Captures of bats were performed by setting mist nets in cave entrances, its interior and surroundings, making a total capture effort of 6,090 m2.h. Our results indicate that this cave is shelter for a rich bat assemblage with fifteen species captured. Carollia perspicillata, Desmodus rotundus and Myotis sp. were the most abundant species. A comparison of the assemblage composition with that of other caves of Sao Paulo state revealed that its composition is very similar and typical of the Atlantic Forest Atlantic cave chiropterofauna independently of cave lithology. A multiple regression analysis performed to check for the existence of correlation between the seasonal fluctuation of the climatic variables temperature, pluviosity and air humidity did not reveal significant relationships among these and the changes in the abundance of bats. However, the analysis of canonical correspondence including these variables and also moonlight luminosity indicated a significant relationship of the changes in bat abundance with the air relative humidity. Changes in bat abundances are probably related to the seasonality in food availability. The accumulation curve obtained from the relationship between the accumulated richness of species and the number of samples showed that more samplings are required to reach the asymptote of species richness. Considering that Gruta do Riacho Subterrâneo is the largest granitic cave in Brazil and that it shelters a high number of bat species, including common and rare species, we suggests the preservation of this cave for maintenance of bat diversity in Sao Paulo state.
Studies on free and nano-encapsulated Lactobacillus casei under simulated gastrointestinal fluid and thermal conditions

Keywords The main goal of this research was to see how nanoencapsulation affected the stability and vitality of the probiotic bacteria in a simulated gastrointestinal digesting and temperature environment. The mechanical encapsulation approach was used to encapsulate probiotics using sodium alginate and pullulan. Further, scanning electron microscopy (SEM) was used to examine the interaction between the capsule matrix and probiotic bacteria in the created nano-capsules. Probiotic bacteria's survival and stability were tested in simulated gastrointestinal, intestinal, thermal, and refrigeration conditions. Nano encapsulation has a considerable impact on probiotic bacteria survival and stability. The viability of probiotic bacteria decreased at a similar rate across all treatments. In contrast, free probiotic cells were shown to have a quick -encapsulated bacteria have a lower reduction in total viable cells than free bacterial cells in an in vitro gastrointestinal assay, but the results of the viable count in the case of nano-encapsulated cells were also above the recommended level (106 CFU/gram) under the thermal and simulated GIT conditions.

A three-phase approach for robust project scheduling: an application for R&D project scheduling

During project execution, especially in a multi-project environment unforeseen events arise that disrupt the project process resulting in deviations of project plans and budgets due to missed due dates and deadlines, resource idleness, higher work-in-process inventory and increased system nervousness. In this thesis, we consider the preemptive resource constrained multi-project scheduling problem with generalized precedence relations in a stochastic and dynamic environment and develop a three-phase model incorporating data mining and project scheduling techniques to schedule the R&D projects of a leading home appliances company in Turkey. In Phase I, models classifying the projects with respect to their resource usage deviation levels and an activity deviation assignment procedure are developed using data mining techniques. Phase II, proactive project scheduling phase, proposes two scheduling approaches using a bi-objective genetic algorithm (GA). The objectives of the bi-objective GA are the minimization of the overall completion time of projects and the minimization of the total sum of absolute deviations for starting times for possible realizations leading to solution robust baseline schedules. Phase II uses the output of the first phase to generate a set of non-dominated solutions. Phase III, called the reactive phase, revises the baseline schedule when a disruptive event occurs and enables the project managers to make “what-if analysis” and thus to generate a set of contingency plans for better preparation.
Experimental realization of the quantum metrological triangle experiment

The quantum metrological triangle experiment (QMTE) consists in realizing Ohm's law with Josephson (JE), quantum Hall (QHE) and single electron tunneling (SET) effects. The aim is to check the consistency of the link among the phenomenological constants K J, RK and Q X involved in these effects and theoretically expressed with the fundamental constants e and h. Such an experiment could be a contribution for a new definition of the système international d'unités (SI) base units. In the QMTE, a current generated by a SET device flows through a resistor calibrated against QHE standard and the voltage induced at its terminals is compared to the metrological voltage generated by a Josephson junctions array. At LNE, the studied SET devices are 3 junctions single electron pumps with on chip resistors. The quantized current generated by this pump is theoretically equal to ef (f is the frequency of the driving signals applied on the gates) and is measured through a cryogenic current comparator (CCC), which allows to amplify the low pumping current with a metrological accuracy. We will present and discuss the experimental set-up developed at LNE and the first results. In addition to the main aim of QMTE described above, these preliminary results are also a first step towards a determination of e.
Mechanical characterization of C60 whiskers by MEMS bend testing

Little has been published on the mechanical characteristics of C60 whiskers, due to the inherent difficulties in physically mounting such small test samples. Earlier reported results suggested Young's modulus values of 32 and 54 GPa, with 130 and 160 micron diameter C60 nanowhiskers, respectively, using compressive deformation techniques. In our work, an experimental bespoke silicon-based microelectromechanical system has been developed to extract an other value. 1th as been found, through parameter extraction techniques, that a Young's modulus of only ∼ 2 GPa is obtained with a C60 whisker having a diameter of 4 microns. By including the previously published data points, there is now strong evidence to suggest an inverse proportionality relationship between the Young's modulus and the diameter of a C60 whisker.
High frequency perturbation formulas for the effect of small inhomogeneities

We derive asymptotic expressions for the scattering effects of small inhomogeneities in the context of the two dimensional Helmholtz equation. Asymptotic refers to the limit as the inhomogeneity size tends to zero. One novelty is that these asymptotic formulas also apply to large frequency, not just finite or zero frequency, as has been considered previously. The derived formulas are compared to numerically simulated solutions of the Helmholtz equation.
A simple model for the spin singlet: mathematical equivalence of non-locality, slave will and conspiracy

A hidden-variable model reproducing the quantum mechanical probabilities for a spin singlet is presented. The model violates only the hypothesis of independence of the distribution for the hidden variables from the detector settings and vice versa (measurement independence). It otherwise satisfies the hypotheses of setting independence, outcome independence—made in the derivation of the Bell inequality—and that of compliance with Malus's law—made in the derivation of the Leggett inequality. It is shown that the violation of the measurement independence hypothesis may be explained alternatively by assuming a non-local influence of the detector settings on the hidden variables, or by taking the hidden variable to influence the choice of settings (limitation of free will), or finally by purporting a conspiracy. It is demonstrated that the last two cases admit a realization through existing local classical resources.
HVMUX, the High Voltage Multiplexing for the ATLAS Tracker Upgrade

The increased luminosity of the HL-LHC will require more channels in the upgraded ATLAS Tracker, as a result of the finer detector segmentation. Thus, an upgraded and more efficient HV biasing of the sensors will also be needed and is among the many technological challenges facing the ATLAS Tracker Upgrade. A number of approaches, including the sharing of the same HV line among several sensors and suitable HV switches, along with their control circuitry are currently being investigated for this purpose. The proposed solutions along with latest test results and measurements will be described.
Ultraviolet divergences, repulsive forces and a spherical plasma shell

We discuss the vacuum energy of the electromagnetic field interacting with a spherical plasma shell together with a model for the classical motion of the shell. We discuss the ultraviolet divergences in terms of the heat kernel coefficients. Using these, we carry out the renormalization by redefining the parameters of the classical model. It turns out that this is possible and that the resulting model has a vacuum energy which changes sign in dependence on the parameters of the plasma shell. In the limit of the plasma shell becoming an ideal conductor the vacuum energy found by Boyer in 1968 is reproduced.
Flow rate measurement of oil-water two-phase flow based on V-cone flow meter

In petroleum industry, oil-water two-phase flow widely exists in production wells, and the measurement of oil-water flow is significant in oil well logging. One method in common use is to build a theoretic model to connect differential pressures generated by a throttling set with flow-rate. Several measuring models were adopted and compared for model selection and modification. A V-cone with 0.65 diameter ratio was selected as the throttling set because of its special structure and intrinsic advantages. In the experiments, the differential pressures measured under different flow range were processed with a homogeneous flow model. And the results show that the error is small in the condition where the oil and water are well mixed, while the error is big when they are not well mixed. A polynomial of the error and the water percentage was fitted to improve the model accuracy and widen the measurement range.
Simple security policy for the web

If web security were a siege, the attackers would be winning: it is relatively easy to compromise a site, but it takes significant resources for a defender to provide even modest security. One of the reasons for this is that current web security technologies are very complex to learn, understand, implement and maintain. As a result, security may be ignored in favour of other concerns. Simple security policy would allow defenders tools that could be used despite other constraints: The web needs simpler policy which can stop basic attacks in order to level the playing field. In this thesis, I demonstrate how several facets of the web can be extended to allow for lightweight policy additions: the same origin policy can be adapted to allow additional restrictions on inclusions and communication as we show with the Same Origin Mutual Approval (SOMA) policy. The visual layout of the page can be leveraged to produce policies that control within-page communications for page elements as we show with Visual Security Policy (ViSP). And finally, cascading style sheets can be adapted to produce an extensible policy that encompasses some of the best mitigation strategies currently available as we show with Security Style Sheets. To show the utility of these policy languages, I give formal models followed by case studies demonstrating how these simple policy languages could be used in practice and how their simplicity makes them especially attractive compared to existing solutions in the web space.
Can accurate investigation of phase stability explain the experimental results of multipactor phenomenon?

The simple two-point theory cannot explain the results of known experimental data of the multipactor (MP) discharge for two-parallel plate. Here the concept of accurate phase stability for resonance and regions not satisfying the resonance condition are presented. In this order the results of numerical simulation and improved theoretical calculation are stated. The results show that the most important thing that can result in a MP discharge is the behaviour of stability factor of the electron during its flights. It seems that introduction of ``main condition'' of phase stability can help to understand the experimental results. In numerical simulation a fixed value for the initial velocity of secondary electron is considered while the random initial rf phase is assumed.
Utilization of Tractor Power using Front Three Point Linkage

With a higher HP tractor it is difficult to take the maximum use of tractor power. Front three-point linkage has been found profitable with these tractors due to higher power requirement and also due to multiple operations in single pass. The importance of this study is to check its feasibility under Indian field conditions. Front three-point linkage are designed and fabricated according to Category II hitch requirements. Hydraulic cylinders are designed to provide hydraulic power to the front linkages. Selection of hydraulic hoses is done according to the requirements and availability. Mechanical front-wheel drive tractor is selected for the test. Laboratory test is carried out to evaluate its lifting performance. Field performance is also done to check its profitability. A field is prepared using cultivator in front and harrow in rear and the performance are calculated.

Alignment of the CMS tracker with LHC and cosmic ray data

The central component of the CMS detector is the largest silicon tracker ever built. The precise alignment of this complex device is a formidable challenge, and only achievable with a significant extension of the technologies routinely used for tracking detectors in the past. This article describes the full-scale alignment procedure as it is used during LHC operations. Among the specific features of the method are the simultaneous determination of up to 200 000 alignment parameters with tracks, the measurement of individual sensor curvature parameters, the control of systematic misalignment effects, and the implementation of the whole procedure in a multi-processor environment for high execution speed. Overall, the achieved statistical accuracy on the module alignment is found to be significantly better than 10μm.

Part I of this three-part series described semiconductor supply chains from the decision-making and functional perspectives, using this as a framework to review the industrial engineering and operations research literature on the problems arising in these supply chains. Part I then reviewed the literature on Strategic Network Design, supply chain coordination, sustainability and simulation-based decision support. This paper, Part II, reviews the areas of Demand Planning, Inventory Management and Capacity Planning in semiconductor supply chains. Part III concludes the series by discussing models to support Master Planning, Production Planning and Demand Fulfilment in this industry.
Is Kelvin representative of an "Irish tradition"?

Kelvin interacted with many physicists and mathematicians with Irish connections, and these interactions are sketched. A number of suggestions of Irish or Irish-Scottish scientific traditions or networks are reviewed, but it is argued that the large number of interactions may be better explained just by the high quality of physics and mathematics in Ireland and Scotland in the nineteenth century. Kelvin's disapproval of science as carried out in Cambridge and London is discussed, and an attack by some of his followers on science at Oxford is also described. Finally a number of examples of Kelvin's most important work are outlined and some general features are pointed out; these include the willingness to tackle practical and engineering problems, and the ability to attempt to construct major syntheses, where appropriate taking note of religious themes, and drawing conclusions, positive or negative, on religious matters. These features are used to construct a highly tentative characterisation of a grouping of Irish and Scottish scientists centred largely round Kelvin.
Strong-field modulated diffraction effects in the correlated electron-nuclear motion in dissociating H2+

By solving the time dependent Schrödinger equation for H2+ in a pump-probe numerical experiment, we found that the electronic motion can follow or oppose the laser electric force. Our results show that the internal electron dynamics in H2+ is determined by both, the external laser field and intra-molecular electron diffraction.
Two different LNA optimizing techniques

Two different LNA design techniques, namely the classical two-port technique and the Shaeffer technique, have been introduced, compared and implemented for practical design. Their merits and drawbacks are also discussed. This paper mainly focuses on the former technique, which is seldom introduced in traditional papers. Since a parasitic capacitor of the transistor is included in the computation of the former technique, the errors caused by the ignorance of the capacitor have been minimized, which is superior to traditional techniques. Using the former technique, a fully integrated LNA is realized with only 1.4 dB while drawing 1.3 mA DC at 2.4 GHz for simulation results. Another version of the LNA is designed using the latter technique, which has been fabricated.
Immunological assessment of varieties of cereal crops relative to the North Caucasian and Belarusian populations of the pathogen of pink snow mold

The article presents the results of an immunological assessment of the North Caucasian (NC) and Belarusian (BL) populations of pink snow mold (pathogen Microdochium nivale (Fr.) Samuels & I.C. Hallett) of 2 triticale varieties, 3 rye varieties, 2 winter barley varieties of Belarusian selection and 11 varieties barley, 20 varieties of winter wheat of Russian selection in the seedling phase. Infectious material was selected from two geographically distant zones - the population of the fungus of the North Caucasus region of the Russian Federation (NC) and the population selected on the crops of the Republic of Belarus (BL). It was revealed that resistance to NC was shown by one variety of winter triticale Grenado with a degree of damage of 3.2 points. Winter rye varieties showed different degrees of susceptibility to both populations: Zazerskaya 3 (NC - 5.0 points, BL 8.2 - points), Forzetti (NC5.2 - points, BL 6.4 - points), Golubka (NC - 5.4 points, BL 7.2 points). High resistance to both pathogen populations was found in the winter barley variety Vivat (NC - 2.8 points, BL - 2.6 points). High resistance relative to both populations was found in winter wheat varieties: Helios (NC - 2.0 points, BL - 2.4 points), Iliad (NC - 2.0 points, BL - 2.8 points) and Soberbash (NC 2, 8 - points, BL 2.8 - points). The degree of plant damage by the Belarusian population of the pathogen of pink snow mold was higher than the North Caucasian population (Ft4.0<Ff4.5) with a moderate degree of correlation of damage by different populations (rxy=0.33), which indicates a higher aggressiveness of the pathogen common on crops grain crops of Belarus.
