description: This paper aims to study the asymptotic behaviour of the fundamental solutions (heat kernels) of non-local (partial and pseudo differential) equations with fractional operators in time and space. In particular, we obtain exact asymptotic formulas for the heat kernels of time-changed Brownian motions and Cauchy processes. As an application, we obtain exact asymptotic formulas for the fundamental solutions to the $n$-dimensional fractional heat equations in both time and space \begin{gather*} \frac{\partial^β}{\partial t^β}u(t,x) = -(-Δ_x)^γu(t,x), \quad β,γ\in(0,1). \end{gather*}

description: The authors describe ACT-R/perceptual-motor (ACT-R/PM), an integrated theory of cognition, perception, and action that consists of the ACT-R production system and a set of perceptual-motor modules. Each module (including cognition) is essentially serial, but modules run in parallel with one another. ACT-R/PM can model simple dual tasks such as the psychological refractory period (PRP), including subtle results previously explained with executive process interactive control (EPIC, D. E. Meyer & D. E. Kieras, 1997a). The central difference between the theories is that EPIC's productions can fire in parallel, whereas in ACT-R/PM, they are serial. Results from three PRP-like experiments with more demanding cognitive requirements indicate that cognitive processing for the 2 tasks need not overlap. ACT-R's activation-based retrieval processes are critical in accounting for the timing of these tasks and for explaining the dual-task performance decrement.

Subjects: Waste tire, waste tire Pyrolysis, oil and solid char.

description: Scrap tires have a high content of volatile matters and fixed carbon. Their disposal has lost only a small percentage of their original mass, the same in their physical and chemical properties as compared to the new tires. Therefore, recycling scrap tires as a fuel for energy production and the major environmental problem due to them are not biodegradable. Currently in Ethiopia especially in the capital city Addis Ababa, the demand of cars and the need of fuel are increasing due to urbanization. With the increasing demand for cars that makes to increase the need for tire that leads also for scrap tires to the environment increasing. This scrap tires are dumped everywhere place and recycled without any considerations about environmental impact and human health. The overall objective of this research was to assess disposal of scrap tires and their recycling process in to pyrolysis oil and solid char by using pyrolysis methods in Ethiopia. The specific objectives to assess the most available waste tire type in Ethiopia, to study the effects of temperatures and pyrolysis time of on oil and solid char production during pyrolysis and to characterize the oil product. By using gathered data from secondary and primary source found that the most available waste tire type was the imported type of tire. Using pyrolysis methods the sample tire were pyrolyzed in the reactor under N2 atmosphere, the maximum yield of products were obtained oil (24% by wt.) at temperature of 450OC and pyrolysis time 60min and char (41.94%wt.) at temperature 450OC and pyrolysis time 30min. The density, caloric value and viscosity of oil was found to be 857.14 kg
 ���� 3 , 42.9MJ/kg and 4.8cSt, respectively and Ash and caloric value solid char was found to be 15.95% and 28.25MJ/kg. The factorial experimental design and statistical analysis done by Design-Expert 7.0.0 Software and temperature was highly significant effect on the products of oil and carbon black yield. Hence, the properties of product result shown encourage their use as replacement for conventional fuel and as fillers, pigments.

description: With the increasing digital services demand, performance and power-efficiency become vital requirements for digital circuits and systems. However, the enabling CMOS technology scaling has been facing significant challenges of device uncertainties, such as process, voltage, and temperature variations. To ensure system reliability, worst-case corner assumptions are usually made in each design level. However, the over-pessimistic worst-case margin leads to unnecessary power waste and performance loss as high as 2.2x. Since optimizations are traditionally confined to each specific level, those safe margins can hardly be properly exploited. To tackle the challenge, it is therefore advised in this Ph.D. thesis to perform a cross-layer optimization for digital signal processing circuits and systems, to achieve a global balance of power consumption and output quality. To conclude, the traditional over-pessimistic worst-case approach leads to huge power waste. In contrast, the adaptive voltage scaling approach saves power (25% for the CORDIC application) by providing a just-needed supply voltage. The power saving is maximized (46% for CORDIC) when a more aggressive voltage over-scaling scheme is applied. These sparsely occurred circuit errors produced by aggressive voltage over-scaling are mitigated by higher level error resilient designs. For functions like FFT and CORDIC, smart error mitigation schemes were proposed to enhance reliability (soft-errors and timing-errors, respectively). Applications like Massive MIMO systems are robust against lower level errors, thanks to the intrinsically redundant antennas. This property makes it applicable to embrace digital hardware that trades quality for power savings.

description: Primordial non-Gaussianity has emerged as one of the most promising probes of the inflationary epoch. While the cosmic microwave background and large-scale halo bias currently provide the most stringent constraints on the non-Gaussian parameter fNL, the abundance of dark matter halos is a complementary probe which may allow tests of Gaussianity which are independent of the precise form of non-Gaussian initial conditions. We study the halo mass function in N-body simulations with a range of non-Gaussian initial conditions. In addition to the usual fNL model, we consider gNL Phi^3-type non-Gaussianity and models where the 4-point amplitude tauNL is an independent parameter. We introduce a new analytic form for the halo mass function in the presence of primordial non-Gaussianity, the "log-Edgeworth" mass function, and find good agreement with the N-body simulations. The log-Edgeworth mass function introduces no free parameters and can be constructed from first principles for any model of primordial non-Gaussianity.

Aspherical supernova explosions and formation of compact black hole low-mass X-ray binaries
Creators: name: Li, Xiang-Dong
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: It has been suggested that black-hole low-mass X-ray binaries (BHLMXBs) with short orbital periods may have evolved from BH binaries with an intermediate-mass secondary, but the donor star seems to always have higher effective temperatures than measured in BHLMXBs (Justham, Rappaport & Podsiadlowski 2006). Here we suggest that the secondary star is originally an intermediate-mass ($\sim 2-5 M_{\sun}$) star, which loses a large fraction of its mass due to the ejecta impact during the aspherical SN explosion that produced the BH. The resulted secondary star could be of low-mass ($\la 1 M_{\sun}$). Magnetic braking would shrink the binary orbit, drive mass transfer between the donor and the BH, producing a compact BHLMXB.

description: We report the effect of different sequences of high vs low levels of instructional guidance on children’s immediate learning and long-term transfer of simple experimental design procedures and concepts, often called “CVS” (Control of Variables Strategy). Third-grade children (N = 57) received instruction in CVS via one of four possible orderings of high or low instructional guidance: high followed by high (HH), high followed by low (HL), low followed by high (LH), and low followed by low (LL). High guidance instruction consisted of a combination of direct instruction and inquiry questions, and low guidance included only inquiry questions. Contrary to the frequent claim that a high degree of instructional guidance leads to shallow learning and transfer, across a number of assessments—including a 5-month post-test—the HH group demonstrated a stronger understanding of CVS than the LL group. Moreover, we found no advantage for preceding high guidance with low guidance. We discuss our findings in relation to perspectives advocating “invention as preparation for future learning”, and the efficacy of “productive failure”.
ASSESSMENT OF LAND USE/COVER CHANGE AND MANAGEMENT IMPACTS ON HYDROLOGY: THE CASE OF GADO CATCHMENT, ETHIOPIA
Creators: name: TSEGAYE DEBEBE MELESE
Publisher: name: National Academic Digital Repository of Ethiopia

description: For the past thirty years, a growth in population pressure caused change in the land cover and
 management in Gado catchment. Gado is a catchment found in Abay river basin of Ethiopia
 affected by human induced factors causing deforestation and improper land management which
 in turn affects the catchment hydrological components. This study is mainly focused on the
 assessment of changes in stream flow magnitude due to land cover and management using
 ERDAS imagine and Geographic information system (GIS) integrated with soil and water
 assessment tool (SWAT). The assessment on the land cover indicated that the forest cover
 decreased by 32.01% between the years 1987-2000, while it was decreased by 149.31% between
 the years 2000-2014. Likewise, the dominant Bush/Shrubs cover in the mid 1980’s around the
 upper most highlands and lower portions of the catchment greatly changed for the study period
 from 23.99% to 2.91%. The grass/grazing land rate of change followed similar trend (from 17.77
 to 12.31% reduction) between 1987 and 2014. This was mainly due to the expansion of
 cultivated and settlement land from 19.2% to 68.96% during the period of 1987−2014. SWAT
 was applied to evaluate the change in stream flow magnitude due to land cover and
 management, and the results show that changes in stream flow could be related to the change of
 the land cover and management in Gado catchment. Based on model result, stream flow was
 analysed to evaluate if changes in land cover and management affected stream flow. The
 simulated mean annual discharge had changed from 19.62m3/s to 20.09 m3/s. The result
 indicates that there was insignificant change in stream flow through time periods of 1987 to
 2014 due to soil conservations and management practices in the study area.

description: Several results of large deviations are obtained for distributions that are associated with the Poisson--Dirichlet distribution and the Ewens sampling formula when the parameter $θ$ approaches infinity. The motivation for these results comes from a desire of understanding the exact meaning of $θ$ going to infinity. In terms of the law of large numbers and the central limit theorem, the limiting procedure of $θ$ going to infinity in a Poisson--Dirichlet distribution corresponds to a finite allele model where the mutation rate per individual is fixed and the number of alleles going to infinity. We call this the finite allele approximation. The first main result of this article is concerned with the relation between this finite allele approximation and the Poisson--Dirichlet distribution in terms of large deviations. Large $θ$ can also be viewed as a limiting procedure of the effective population size going to infinity. In the second result a comparison is done between the sample size and the effective population size based on the Ewens sampling formula.

description: Community analysis is an important way to ascertain whether or not a complex system consists of sub-structures with different properties. In this paper, we give a two level community structure analysis for the SSCI journal system by most similar co-citation pattern. Five different strategies for the selection of most similar node (journal) pairs are introduced. The efficiency is checked by the normalized mutual information technique. Statistical properties and comparisons of the community results show that both of the two level detection could give instructional information for the community structure of complex systems. Further comparisons of the five strategies indicates that, the most efficient strategy is to assign nodes with maximum similarity into the same community whether the similarity information is complete or not, while random selection generates small world local community with no inside order. These results give valuable indication for efficient community detection by most similar node pairs.

description: In this paper, a system architecture is proposed that approximately models the functionality of metabolic networks. The AND/OR graph model is used to represent the metabolic network and each processing element in the system emulates the functionality of a metabolite. The system is implemented on a graphics processing unit (GPU) as the hardware platform using CUDA environment. The proposed architecture takes advantage of the inherent parallelism in the network structure in terms of both pathway and metabolite traversal. The function of each element is defined such that it can find flux-balanced pathways. Pathways in both small and large metabolic networks are applied to the proposed architecture and the results are discussed.

description: A traditionally desired goal when designing auction mechanisms is incentive compatibility, i.e., ensuring that bidders fare best by truthfully reporting their preferences. A complementary goal, which has, thus far, received significantly less attention, is to preserve privacy, i.e., to ensure that bidders reveal no more information than necessary. We further investigate and generalize the approximate privacy model for two-party communication recently introduced by Feigenbaum et al.[8]. We explore the privacy properties of a natural class of communication protocols that we refer to as "dissection protocols". Dissection protocols include, among others, the bisection auction in [9,10] and the bisection protocol for the millionaires problem in [8]. Informally, in a dissection protocol the communicating parties are restricted to answering simple questions of the form "Is your input between the values αand β(under a predefined order over the possible inputs)?". We prove that for a large class of functions, called tiling functions, which include the 2nd-price Vickrey auction, there always exists a dissection protocol that provides a constant average-case privacy approximation ratio for uniform or "almost uniform" probability distributions over inputs. To establish this result we present an interesting connection between the approximate privacy framework and basic concepts in computational geometry. We show that such a good privacy approximation ratio for tiling functions does not, in general, exist in the worst case. We also discuss extensions of the basic setup to more than two parties and to non-tiling functions, and provide calculations of privacy approximation ratios for two functions of interest.

description: Sibley, Kello, Plaut, and Elman (2008) proposed the sequence encoder as a model that learns fixed-width distributed representations of variable-length sequences. In doing so, the sequence encoder overcomes problems that have restricted models of word reading and recognition to processing only monosyllabic words. Bowers and Davis (in press) recently claimed that the sequence encoder does not actually overcome the relevant problems, and hence is not a useful component of large-scale word reading models. In this reply, it is noted that the sequence encoder has facilitated the creation of large-scale word reading models. The reasons for this success are explained, and stand as counterarguments to claims made by Bowers and Davis.

description: We investigate properties of iron fluorescent line arising as a result of illumination of a black hole accretion disc by an X-ray source located above the disc surface. We study in details the light-bending model of variability of the line, extending previous work on the subject. We indicate bending of photon trajectories to the equatorial plane, which is a distinct property of the Kerr metric, as the most feasible effect underlying reduced variability of the line observed in several objects. A model involving an X-ray source with a varying radial distance, located within a few central gravitational radii around a rapidly rotating black hole, close to the disc surface, may explain both the elongated red wing of the line profile and the complex variability pattern observed in MCG--6-30-15 by XMM-Newton. We point out also that illumination by radiation which returns to the disc (following the previous reflection) contributes significantly to formation of the line profile in some cases. As a result of this effect, the line profile always has a pronounced blue peak (which is not observed in the deep minimum state in MCG--6-30-15), unless the reflecting material is absent within the innermost 2--3 gravitational radii.

Including these J terms explicitly allows us to enhance the strength of the (pi, 0)-(0, pi) spin order which favors the presence of tightly bound pairing states even in the small clusters that are here exactly diagonalized. The A1g and B2g pairing symmetries are found to compete in the realistic spin-ordered and metallic regime. The dynamical pairing susceptibility additionally unveils low-lying B1g states, suggesting that small changes in parameters may render any of the three channels stable.

description: Quantization can be used to form new vectors/matrices with shared values close to the original. In recent years, the popularity of scalar quantization for value-sharing applications has been soaring as it has been found huge utilities in reducing the complexity of neural networks. Existing clustering-based quantization techniques, while being well-developed, have multiple drawbacks including the dependency of the random seed, empty or out-of-the-range clusters, and high time complexity for a large number of clusters. To overcome these problems, in this paper, the problem of scalar quantization is examined from a new perspective, namely sparse least square optimization. Specifically, inspired by the property of sparse least square regression, several quantization algorithms based on $l_1$ least square are proposed. In addition, similar schemes with $l_1 + l_2$ and $l_0$ regularization are proposed. Furthermore, to compute quantization results with a given amount of values/clusters, this paper designed an iterative method and a clustering-based method, and both of them are built on sparse least square. The paper shows that the latter method is mathematically equivalent to an improved version of k-means clustering-based quantization algorithm, although the two algorithms originated from different intuitions. The algorithms proposed were tested with three types of data and their computational performances, including information loss, time consumption, and the distribution of the values of the sparse vectors, were compared and analyzed. The paper offers a new perspective to probe the area of quantization, and the algorithms proposed can outperform existing methods especially under some bit-width reduction scenarios, when the required post-quantization resolution (number of values) is not significantly lower than the original number.

description: Unraveling the stratigraphic record is the key to understanding ancient climate and past climate changes on Mars. River deposits when placed in stratigraphic order could constrain the number, magnitudes, and durations of the wettest climates in Mars history. We establish the stratigraphic context of river deposits in Aeolis Dorsa sedimentary basin, 10E of Gale crater. Here, wind has exhumed a stratigraphic section of >=4 unconformity-bounded sedimentary rock packages, recording >=3 distinct episodes of surface runoff. Early deposits (>700m thick) are embayed by river deposits (>400m), which are in turn unconformably draped by fan-shaped deposits (<100m) which we interpret as alluvial fans. Yardang-forming deposits (>900 m) unconformably drape all previous deposits. River deposits embay a dissected sedimentary-rock landscape, and comprise >=2 distinguishable units. The total interval spanned by river deposits is >(1x10^6-2x10^7) yr; more if we include alluvial-fan deposits. Alluvial-fan deposits unconformably postdate thrust faults which crosscut river deposits. We infer a relatively dry interval of >4x10^7 yr after river deposits formed and before fan-shaped deposits formed. The time gap between the end of river deposition and the onset of yardang-forming deposits is constrained to >10^8 yr by the density of impact craters embedded at the unconformity. We correlate yardang-forming deposits to the upper layers of Gale crater's mound (Mt. Sharp/Aeolis Mons), and fan-shaped deposits to Peace Vallis fan. Alternations between periods of low vs. high mean obliquity may have modulated erosion-deposition cycling in Aeolis. This is consistent with results from an ensemble of simulations of Solar System orbital evolution and the resulting history of Mars obliquity. Almost all simulations yield intervals of continuously low mean Mars obliquity that are long enough to match our unconformity data.

description: Comprehending high-imagery sentences like The number eight when rotated 90 degrees looks like a pair of eyeglasses involves the participation and integration of several cortical regions. The linguistic content must be processed to determine what is to be mentally imaged, and then the mental image must be evaluated and related to the sentence. A theory of cortical underconnectivity in autism predicts that the interregional collaboration required between linguistic and imaginal processing in this task would be underserved in autism. This functional MRI study examined brain activation in 12 participants with autism and 13 age- and IQ-matched control participants while they processed sentences with either high- or low-imagery content. The analysis of functional connectivity among cortical regions showed that the language and spatial centres in the participants with autism were not as well synchronized as in controls. In addition to the functional connectivity differences, there was also a group difference in activation. In the processing of low-imagery sentences (e.g. Addition, subtraction and multiplication are all moth skills), the use of imagery is not essential to comprehension. Nevertheless, the autism group activated parietal and occipital brain regions associated with imagery for comprehending both the low and high-imagery sentences, suggesting that they were using mental imagery in both conditions. In contrast, the control group showed imagery-related activation primarily in the high-imagery condition. The findings provide further evidence of underintegration of language and imagery in autism (and hence expand the understanding of underconnectivity) but also show that people with autism are more reliant on visualization to support language comprehension.

description: We consider the phenomenon of quantum charge pumping of electrons across a superconducting double barrier structure in graphene in the adiabatic limit. In this geometry, quantum charge pumping can be achieved by modulating the amplitudes (Delta_1 and Delta_2) of the gaps associated with the two superconducting strips. We show that the superconducting gaps give rise to a transmission resonance in the Delta_1-Delta_2 plane, resulting in a large value of pumped charge, when the pumping contour encloses the resonance. This is in sharp contrast to the case of charge pumping in a normal double barrier structure in graphene, where the pumped charge is very small, due to the phenomenon of Klein tunneling. We analyse the behaviour of the pumped charge through the superconducting double barrier geometry as a function of the pumping strength and the phase difference between the two pumping parameters, for various angles of the incident electron.

description: L’impegno teorico e didattico di Giuseppe Lombardo Radice fu fortemente orientato a valorizzare la figura dei maestri di scuola primaria. Fra gli anni Dieci e gli anni Trenta del Novecento, egli portò avanti una vera e propria battaglia culturale e politica a favore del potenziamento della preparazione dei maestri e della loro responsabilizzazione nella costruzione della vita nazionale. L’attenzione di Lombardo Radice si è concentrata soprattutto sui protagonisti dell’istruzione popolare, in quanto promotori del riscatto dell’Italia ancora dimenticata e di un paziente e tenace lavoro di emancipazione sociale.


 

Giuseppe Lombardo Radice's theoretical and educational efforts were strongly oriented toward enhancing the figure of primary school teachers. Between the 1910s and 1930s, he carried on a real cultural and political battle in favor of empowering the training of teachers and making them responsible for the building of national life. Lombardo Radice's attention focused above all on the protagonists of popular education, as promoters of the redemption of the still forgotten Italy and of a tenacious and patient work of social emancipation.

Ram pressure histories of cluster galaxies

description: Ram pressure stripping can remove significant amounts of gas from galaxies that orbit in clusters and massive groups, and thus has a large impact on the evolution of cluster galaxies. In this paper, we reconstruct the present-day distribution of ram-pressure, and the ram pressure histories of cluster galaxies. To this aim, we combine the Millennium Simulation and an associated semi-analytic model of galaxy evolution with analytic models for the gas distribution in clusters. We find that about one quarter of galaxies in massive clusters are subject to strong ram-pressures that are likely to cause an expedient loss of all gas. Strong ram-pressures occur predominantly in the inner core of the cluster, where both the gas density and the galaxy velocity are higher. Since their accretion onto a massive system, more than 64 per cent of galaxies that reside in a cluster today have experienced strong ram-pressures of $>10^{-11}$ dyn cm$^{-2}$ which most likely led to a substantial loss of the gas.

description: We are trying to implement deep neural networks in the edge computing environment for real-world applications such as the IoT(Internet of Things), the FinTech etc., for the purpose of utilizing the significant achievement of Deep Learning in recent years. Especially, we now focus algorithm implementation on FPGA, because FPGA is one of the promising devices for low-cost and low-power implementation of the edge computer. In this work, we introduce Binary-DCGAN(B-DCGAN) - Deep Convolutional GAN model with binary weights and activations, and with using integer-valued operations in forward pass(train-time and run-time). And we show how to implement B-DCGAN on FPGA(Xilinx Zynq). Using the B-DCGAN, we do feasibility study of FPGA's characteristic and performance for Deep Learning. Because the binarization and using integer-valued operation reduce the memory capacity and the number of the circuit gates, it is very effective for FPGA implementation. On the other hand, the quality of generated data from the model will be decreased by these reductions. So we investigate the influence of these reductions.

description: Recently, inhomogeneous generalisations of the Friedmann-Lemaitre-Robertson-Walker cosmological models have gained interest in the astrophysical community and are more often employed to study cosmological phenomena. However, in many papers the inhomogeneous cosmological models are treated as an alternative to the FLRW models. In fact, they are not an alternative, but an exact perturbation of the latter, and are gradually becoming a necessity in modern cosmology. The assumption of homogeneity is just a first approximation introduced to simplify equations. So far this assumption is commonly believed to have worked well, but future and more precise observations will not be properly analysed unless inhomogeneities are taken into account. This paper reviews recent developments in the field and shows the importance of an inhomogeneous framework in the analysis of cosmological observations.

description: Prior research suggests that preschoolers can generalize object properties based on category information conveyed by semantically-similar labels. However, previous research did not control for co-occurrence probability of labels in natural speech. The current studies re-assessed children's generalization with semantically-similar labels. Experiment 1 indicated that adults made category-based inferences regardless of co-occurrence probability; however, 4-year-olds generalized with semantically-similar labels that co-occurred in child-directed speech (e.g., bunny-rabbit) but not with non-co-occurring labels (e.g., crocodile-alligator). Experiment 2 indicated that generalization with semantically-similar labels increased gradually between 4- and 6-years of age. These results are discussed in relation to theories of early learning.

description: We study the role of magnetic interaction in the photoproduction of the kaon and hyperon. We find that the inclusion of a higher order diagram induced by the Wess-Zumio-Witten term has a significant contribution to the magnetic amplitude, which is compatible to the observed photon asymmetry in the forward angle region. This enables us to use the K^* coupling constants which have been determined in a microscopic way rather than the phenomenological ones which differ largely from the microscopic ones.
