Oxygen and Carbon Isotope Analyses of Tertiary and Cretaceous Microfossils from Shatsky Rise and Other Sites in the North Pacific Ocean

Oxygen and carbon isotopes were determined for nannofossils and foraminifera of Tertiary and Cretaceous age recovered at sites drilled on Shatsky and Hess rises during Leg 32. Additional samples of microfossils from other DSDP sites on Shatsky Rise and on Magellan Rise were also analyzed for comparative purposes. Progressive lithification in pelagic carbonate sediments results in the partial isotopic adjustment of microfossil calcite as dissolved CaCCh is deposited as overgrowth cement. In this process nannofossils, particularly discoasters, are preferentially overgrown and show the largest isotopic adjustment. Nannofossils from midTertiary sediments yield δ θ u values that differ from associated planktonic foraminifera by more than 1.0 per mil, although the original isotopic composition of the two groups was similar. Only nannofossils from depths of burial of less than about 200 meters, where little cement overgrowth has occurred, retain their original isotopic composition. Foraminifera, which tend to act as donors in the CaCθ3 transfer, are less affected isotopically by diagenesis. Planktonic foraminifera retain their isotopic composition from sediments as old as Late Cretaceous at Site 305 and benthonic species from Early Cretaceous sediments at Site 306. Because of their different preservation characteristics, foraminifera are more reliable isotopic paleotemperature indicators than are nannofossils. Microfossils from Shatsky Rise yield oxygen-isotope paleotemperatures that suggest a warming trend in the Early Cretaceous, a thermal maximum in the Albian, and a cooling trend in the Late Cretaceous. Bottom-water temperatures were warm, and the difference between surface waters and bottom waters in tropical regions was less than one-half of the present-day value. There is a small drop in temperature across the Cretaceous-Tertiary boundary which begins in the latest Campanian and ends in the Paleocene. The change in the central Pacific corresponds to approximately 2.5°C in surface waters and 3°C in bottom waters.
Satellite studies of magnetospheric substorms on August 15, 1968. IX - Phenomenological model for substorms.

Observations made during three substorms on August 15, 1968, are shown to be consistent with current theoretical ideas about the cause of substorms. The phenomenological model described in several preceding papers is further expanded. This model follows closely the theoretical ideas presented more quantitatively in recent papers by Coronti and Kennel (1972 and 1973).

Measuring the Irreversibility of Numerical Schemes for Reversible Stochastic Differential Equations

For a Markov process the detailed balance condition is equivalent to the time-reversibility of the process. For stochastic differential equations (SDE's) time discretization numerical schemes usually destroy the property of time-reversibility. Despite an extensive literature on the numerical analysis for SDE's, their stability properties, strong and/or weak error estimates, large deviations and infinite-time estimates, no quantitative results are known on the lack of reversibility of the discrete-time approximation process. In this paper we provide such quantitative estimates by using the concept of entropy production rate, inspired by ideas from non-equilibrium statistical mechanics. The entropy production rate for a stochastic process is defined as the relative entropy (per unit time) of the path measure of the process with respect to the path measure of the time-reversed process. By construction the entropy production rate is nonnegative and it vanishes if and only if the process is reversible. Crucially, from a numerical point of view, the entropy production rate is an {\em a posteriori} quantity, hence it can be computed in the course of a simulation as the ergodic average of a certain functional of the process (the so-called Gallavotti-Cohen (GC) action functional). We compute the entropy production for various numerical schemes such as explicit Euler-Maruyama and explicit Milstein's for reversible SDEs with additive or multiplicative noise. Additionally, we analyze the entropy production for the BBK integrator of the Langevin processes. We show that entropy production is an observable that distinguishes between different numerical schemes in terms of their discretization-induced irreversibility. Furthermore, our results show that the type of the noise critically affects the behavior of the entropy production rate.

1 Entity-BasedQuery Recommendation for Long-TailQueries

Query recommendation, which suggests related queries to search engine users, has attracted a lot of attention in recent years. Most of the existing solutions, which perform analysis of users’ search history (or query logs), are often insufficient for long-tail queries that rarely appear in query logs. To handle such queries, we study the use of entities found in queries to provide recommendations. Specifically, we extract entities from a query, and use these entities to explore new ones by consulting an information source. The discovered entities are then used to suggest new queries to the user. In this paper, we examine two information sources: (1) a knowledge base (or KB), such as YAGO and Freebase; and (2) a click log, which contains the URLs accessed by a query user. We study how to use these sources to find new entities useful for query recommendation. We further study a hybrid framework that integrates different query recommendation methods effectively. As shown in the experiments, our proposed approaches provide better recommendations than existing solutions for long-tail queries. In addition, our query recommendation process takes less than 100ms to complete. Thus, our solution is suitable for providing online query recommendation services for search engines.
Dynamic Mechanical Behavior of Luffa cylindrica Fiber-Resorcinol Composites

Dynamic mechanical behaviour of resorcinol-formaldehyde matrix and its composites reinforced with natural fibers of Luffa cylindrica (LC) has been studied. The effects of fiber loading, alkali treatment on fiber, temperature and frequency on storage modulus and mechanical-loss factor of the composites were studied. The dynamic mechanical behaviour of the composites and pure matrix has been investigated in the frequency range from 0.1 Hz to 10 Hz and temperature range from 26℃ to 100℃. The experimental results show that the values of storage modulus of the composites increase with increase in fiber loading. The storage modulus of treated LC fiber composites were found to be enhanced when compared with the untreated fiber composites. It was also found that mechanical-loss factor was more when untreated LC fibers were incorporated in the composites and decreased with the incorporation of treated LC fiber. The storage modulus of all the composites increased with frequency but decreased with rise of temperature. The glass transition temperature of the composites was evaluated from the peaks of tan delta variations.
Garbage collector for memory intensive applications on NUMA architectures

Large-scale multicore architectures create new challenges for garbage collectors (GCs). On contemporary cache-coherent Non-Uniform Memory Access (ccNUMA) architectures, applications with a large memory footprint suffer from the cost of the garbage collector (GC), because, as the GC scans the reference graph, it makes many remote memory accesses, saturating the interconnect between memory nodes. In this thesis, we address this problem with NumaGiC, a GC with a mostly-distributed design. In order to maximise memory access locality during collection, a GC thread avoids accessing a different memory node, instead notifying a remote GC thread with a message; nonetheless, NumaGiC avoids the drawbacks of a pure distributed design, which tends to decrease parallelism and increase memory access imbalance, by allowing threads to steal from other nodes when they are idle. NumaGiC strives to find a perfect balance between local access, memory access balance, and parallelism. In this work, we compare NumaGiC with Parallel Scavenge and some of its incrementally improved variants on two different ccNUMA architectures running on the Hotspot Java Virtual Machine of OpenJDK 7. On Spark and Neo4j, two industry-strength analytics applications, with heap sizes ranging from 160 GB to 350 GB, and on SPECjbb2013 and SPECjbb2005, NumaGiC improves overall performance by up to 94% over Parallel Scavenge, and increases the performance of the collector itself by up to 5.4× over Parallel Scavenge. In terms of scalability of GC throughput with increasing number of NUMA nodes, NumaGiC scales substantially better than Parallel Scavenge for all the applications. In fact in case of SPECjbb2005, where inter-node object references are the least among all, NumaGiC scales almost linearly.
Motivation and control in the Mondragon experiment. and Replication and sustainability of the Mondragon experiment

This paper examines the commercial success of the Mondragon experiment. Specifically, it addresses the question of whether this success can be attributed to its cooperative organization, i.e. the constellation of ownership patterns, rules, and community relations which are so distinctively part of Mondragon. Survey and interview results suggest that cooperative organization is significantly associated with success. Theoretically at least, cooperation contributes to efficiency by rendering more effective traditional vertical control by reducing resistance and by generating pressures towards horizontal reinforcement. Mondragon plausibly does both. Vertical control is improved by the generation and sustaining of concensus and high-trust relationships within the enterprise. Horizontal reinforcement is induced through dispersion of shareholdings and appreciation of the role of effort in the success of the enterprise. A disciplined environment is maintained, therefore, without causing undue opposition or perception of strict discipline. However, attributing causal significance to correlation may be premature. Many issues make the potential replicability of Mondragon a difficult question.
Potential of the Jerivá Fruit (Syagrus romanzoffiana C.): Physicochemical and Bioactive Characterization

Background: Jerivá is a native palm tree from Brazil, very abundant in the rural environment and widely observed in the urban area. Its fruits can be consumed in fresh and drink form. Despite this context there are few studies on the species, especially when portraying the nutritional value of its fruit. This research aims to investigate jerivá fruits in three ripening stages.Methods: The fruits were harvested in a domestic orchard in Campos dos Goytacazes-RJ, in three ripening stages, according to the color: green (green peel), intermediate (yellowish green peel) and ripe (orange peel). The fruits were characterized in terms of physicochemical and bioactive composition.Result: This fruit has a low source of ascorbic acid in all evaluated stages, but has high levels for yellow flavonoids and total extractable polyphenols when mature (23.07 mg/100 g and 596.95 mg GAE/100 g, respectively). Considering the relevance of this fruit species and the few researches at national level, it is necessary to evaluate the physicochemical and bioactive characteristics of the fruits of Jerivá, in order to quantify particularities regarding the detailed composition, guaranteeing its potential for use.
An Usability Constraint Model & Information Preserving Watermarking Scheme for Novel Rights Protection of EMR System with Multivariate Data

The Electronic Medical Records (EMR) is a set of application and workflow that digitizes the creation, collection, storage and management of patient information. The use of EMR enables physicians to do accurate and effective diagnosis. The interoperable EMR systems are becoming the top priority in the world. Acceleration in the use of electronic medical records may lead to an increase in personal health information theft, unauthorized access and illegal sale to third parties. In order to avert such a situation, the EMR data need to be right protected so that an unauthorized party might be sued in a court of law. The ownership rights protection of EMR dataset is possible through a well-known technique of watermarking. The challenges associated with watermarking EMR would be corrupt medical record that may lead to misdiagnoses and attacks for corrupting watermark. Thus a specialized model is proposed for ownership rights protection of EMR system with multivariate attributes having both numeric and nonnumeric data using a usability constraint model and information preserving watermarking scheme. The watermarking process is modeled as a constrained optimization problem using particle swarm optimization (PSO). The decoding of watermark is done using a majority voting scheme.

The Wage Distribution Across the Life-Cycle and the Role of Unemployment Beneflts: France versus the US

The way wage increases along the life-cycle of workers is not homogenous between France and the US. Indeed the discrepancy between the seniors and the young’s wages is wider in France than in the US at the end of the distribution and wider in the US than in France at the bottom of it. Besides, seniors’employment rate is far lower in France than in the US. We propose to explain these facts thanks to a model based on the Burdett and Mortensen (1998) framework with life-cycle. We consider the difference between France and the US in terms of unemployment benefits. Indeed when French workers enjoy rather high and progressive unemployment benefits, the American workers have rather low and flat benefits. We assume therefore that the high and progressive unemployment benefits induce the selection effect responsible for the facts on employment and wage distributions. We first find that the endogenous productivity, the frictions, and the ”on the job search” assumptions are enough to account for the difference between the young’s and the seniors’wages. Then, by introducing high and progressive unemployment benefits consistent with French labor market, we find that this difference is larger especially for the higher wages and that the seniors’employment rate decreases sharply.
Emergy perspectives on the environmental performance and sustainability of small-scale gold production systems in Ghana

Small-scale gold mining is an important component of the Ghanaian economy but it has also caused enormous damage to local ecosystems. In this paper, an emergy analysis was conducted in Ghana to assess the environmental performance and the relative sustainability of two artisanal and small-scale gold production systems: alluvial “dig and wash” and underground “ghetto” mines. Results show that both production systems have high environmental impacts, as indicated by an environmental loading ratio (ELR) of 4.31 and environmental sustainability index (ESI) of 0.33 for the alluvial system and 2.53 and 0.52 for the underground system, respectively. Concerning the international trade balance, the emergy exchange ratios of the two systems are both lower than one, at, 0.23 and 0.33 for the alluvial and underground systems, respectively, indicating a significant amount of resource loss to foreign regions. This study could assist in the regulation of the small-scale mining sector bearing in mind the unsustainable nature of their activities. In addition, supporting miners to consider land rehabilitation ethics is urgently needed.
Some Details of Statistical Mechanics of Many-Body Systems in the Presence of a Measurable Minimal Length

Different approaches to quantum gravity proposal such as string theory, doubly special relativity, and also black holes physics, all commonly address the existence of a minimal measurable length of the order of the Planck length. One way to apply the minimal length is changing the Heisenberg algebra in the phase space which is known as the generalized uncertainty principle. It is essential to apply this feature on the statistical mechanics of many body systems in the presence of a measurable minimal length scale in order to see the roles of this natural cutoff on physical phenomena. In this paper, some details of statistical mechanics of many body systems that have not been studied carefully in literature are studied in the presence of minimal length scale. The issues such as isomerization, the Liouville theorem, virial theorem and equipartition theorem are studied in this setup with details and the results are explained thoroughly.
Bayesian Inference in Physics-Driven Problems with Adversarial Priors

Generative adversarial networks (GANs) have found multiple applications in the solution of inverse problems in science and engineering. These applications are driven by the ability of these networks to learn complex distributions and to map the original feature space to a low-dimensional latent space. In this manuscript we consider the use of GANs as priors in physics-driven Bayesian inference problems. Within this approach the posterior distribution is learnt by mapping the problem to the latent space of the GAN and then using an HMC sampler for efﬁcient sampling. We apply this approach to solving linear and nonlinear inverse problems, including an example with experimental data acquired from an application in biophysical imaging. Furthermore, we analyze the weak convergence of the approximate prior to the true prior and elucidate its dependence on the capacity of the network and the number of training samples.
Design Considerations for Remote High-Speed Pressure Measurements of Dynamic Combustion Phenomena

As gas turbine combustion systems evolve to achieve ultra-low emission targets, monitoring and controlling dynamic combustion processes becomes increasingly important. These dynamic processes may include flame extinction, combustion-driven instabilities, or other dynamic combustion phenomena. Pressure sensors can be incorporated into the combustor liner design, but this approach is complicated by the harsh operating environment. One practical solution involves locating the sensor in a more remote location, such as outside the pressure casing. The sensor can be connected to the measurement point by small diameter tubing. Although this is a practical approach, the dynamics of the tubing can introduce significant errors into the pressure measurement. This paper addresses measurement errors associated with semi-infinite coil remote sensing setups and proposes an approach to improve the accuracy of these types of measurements.
flujo electroosmótico transitorio de dos fluidos inmiscibles en un microcanal con potenciales zeta simétricos y asimétricos

The microfluidics study the behavior, precise control and manipulation of fluids in devices built on a geometrically small scale. Therefore, and due to the requirement of the also small volumes that go from microto femto-liters in these devices, the present work develops a study of the electroosmotic flow in transient state for the transport analysis of two immiscible Newtonian fluids through of a microchannel. Considering symmetrical and asymmetric zeta potentials at the channel walls, the governing equations of Poisson-Boltzmann and momentum are solved in analytical and numerical form, respectively. The results show interesting behaviors about the transitory evolution of the flow in relation to different dimensionless parameters that govern the transportation phenomenon; in this way, the prediction of the velocity profiles in parabolic, symmetric or asymmetric forms depending on the magnitude and polarity of the zeta potential is achieved. With this research, it is intended to extend the knowledge of the spatio-temporal numerical analysis of the flow of immiscible fluids in micro-devices and that serves for design proposals for the precise control of injection and transport of samples.
