Efficient resumption of interrupted warehouse loads

Data warehouses collect large quantities of data from distributed sources into a single repository. A typical load to create or maintain a warehouse processes GBs of data, takes hours or even days to execute, and involves many complex and user-defined transformations of the data (e.g., find duplicates, resolve data inconsistencies, and add unique keys). If the load fails, a possible approach is to “redo” the entire load. A better approach is to resume the incomplete load from where it was interrupted. Unfortunately, traditional algorithms for resuming the load either impose unacceptable overhead during normal operation, or rely on the specifics of transformations. We develop a resumption algorithm called DR that imposes no overhead and relies only on the high-level properties of the transformations. We show that DR can lead to a ten-fold reduction in resumption time by performing experiments using commercial software.
Generalized Fourier-Mukai transforms.

The paper sets out a generalized framework for Fourier-Mukai transforms and illustrates their use via vector bundle transforms. A Fourier-Mukai transform is, roughly, an isomorphism of derived categories of (sheaves) on smooth varieties X and Y. We show that these can only exist if the first Chern class of the varieties vanishes and, in the case of vector bundle transforms, will exist if and only if there is a bi-universal bundle on XxY which is "strongly simple" in a suitable sense. Some applications are given to abelian varieties extending the work of Mukai.
Chromatic Bipolar Cell Pathways in the Mouse Retina

Like most mammals, mice feature dichromatic color vision based on short (S) and middle (M) wavelength-sensitive cone types. It is thought that mammals share a retinal circuit that in dichromats compares S- and M-cone output to generate blue/green opponent signals, with bipolar cells (BCs) providing separate chromatic channels. Although S-cone-selective ON-BCs (type 9 in mouse) have been anatomically identified, little is known about their counterparts, the M-cone-selective OFF-BCs. Here, we characterized cone connectivity and light responses of selected mouse BC types using immunohistochemistry and electrophysiology. Our anatomical data indicate that four (types 2, 3a/b, and 4) of the five mouse OFF-BCs indiscriminately contact both cone types, whereas type 1 BCs avoid S-cones. Light responses showed that the chromatic tuning of the BCs strongly depended on their position along the dorsoventral axis because of the coexpression gradient of M- and S-opsin found in mice. In dorsal retina, where coexpression is low, most type 2 cells were green biased, with a fraction of cells (≈14%) displaying strongly blue-biased responses, likely reflecting S-cone input. Type 1 cells were also green biased but did not comprise blue-biased “outliers,” consistent with type 1 BCs avoiding S-cones. We therefore suggest that type 1 represents the green OFF pathway in mouse. In addition, we confirmed that type 9 BCs display blue-ON responses. In ventral retina, all BC types studied here displayed similar blue-biased responses, suggesting that color vision is hampered in ventral retina. In conclusion, our data support an antagonistically organized blue/green circuit as the common basis for mammalian dichromatic color vision.
Hand-in-Hand Combat: Affectionate Touch Promotes Relational Well-Being and Buffers Stress During Conflict

Relational conflict has a considerable impact on relational and personal well-being, but whether that impact is positive or negative depends on how the conflict is managed. Individuals struggle to have constructive conflicts that protect their relationships and avoid excess stress, which can lead to declines in relationship quality over time. The current set of experiments tested whether a brief touch intervention would promote relational well-being and prevent stress during couple conflict discussions. Results indicated that engaging in touch prior to and during conflict was effective to improve couple-members’ conflict behavior and to buffer stress in real (Experiment 1) and imagined (Experiments 2a and 2b) contexts. The results of these experiments suggest that touch may be a simple yet effective intervention for improving couple conflict discussions. In addition, we provide initial evidence that enhanced state security and cognitive interdependence serve as mechanisms underlying these effects.
Comparison of ocular blood flow by doppler evaluation in middle aged type 2 diabetes patients with and without diabetic macular edema

Introduction: The World Health Organization (WHO) has estimated that the number of people diagnosed with Diabetes is 347 million worldwide. Diabetic macular edema (DME) and Diabetic Retinopathy are the main causes of vision loss in Diabetes mellitus. Objective: To compare altered ocular blood flow by Doppler evaluation in middle aged type 2 diabetic patients with and without diabetic macular edema. Materials and Methods: An analytical cross–sectional study was conducted in the out-patient and in-patient department of ophthalmology and the department of radiodiagnosis in a tertiary care hospital including 36 patients in each group (A-with DME & B-without DME). Color doppler was done to evaluate ocular blood flow velocities in internal carotid, ophthalmic and central retinal arteries and central retinal vein. Results: The majority of diabetes patients in developing countries are middle aged (45–64 years of age). Vascular changes and subsequent ocular hemodynamic changes are critical events in the pathogenesis of diabetic retinopathy. Mean Resistivity Index (RI) and Mean Pulsatility Index (PI) in the ophthalmic artery were found to be significantly high in the DME group. Mean end diastolic velocity (EDV) in the common carotid artery was found to be significantly high in the NO DME group than the DME group. In our study, the mean values of Low Density Lipoprotein (LDL) (mg/dl) , Total cholesterol (mg/dl) , Serum urea (mg/dl), Serum creatinine (mg/dl) was found to be higher (Statistically significant) in the DME group as compared to NO DME group. Conclusion: Our findings may indicate disturbances of retinal and choroidal circulation in patients with DME. Further studies with larger groups of patients are needed to understand better the role of retrobulbar hemodynamics in the pathogenesis of Diabetic macular edema. Keywords: Diabetic macular edema, Doppler evaluation, Ocular blood flow
Time-domain and Frequency-domain Reflectometry Type Soil Moisture Sensor Performance and Soil Temperature Effects in Fine- and Coarse-textured Soils

The performances of six time-domain reflectometry (TDR) and frequency-domain reflectometry (FDR) type soil moisture sensors were investigated for measuring volumetric soil-water content (θv) in two different soil types. Soil-specific calibration equations were developed for each sensor using calibrated neutron probe-measured θv. Sensors were also investigated for their performance response in measuring θv to changes in soil temperature. The performance of all sensors was significantly different (P
Channel Simulation and Coded Source Compression

Coded source compression, also known as source compression with helpers, has been a major variant of distributed source compression, but has hitherto received little attention in the quantum regime. This letter treats and solves the corresponding quantum coded source compression through an observation that connects coded source compression with channel simulation. First, we consider classical source coding with quantum side information, where the quantum side information is observed by a helper and sent to the decoder via a classical channel. We derive a single-letter characterization of the achievable rate region for this problem. The direct coding theorem of our result is proved via the measurement compression theory of Winter, a quantum-to-classical channel simulation. Our result reveals that a helper's scheme which separately conducts a measurement and a compression is suboptimal, and measurement compression seems necessary to achieve the optimal rate region. We then study coded source compression in the fully quantum regime, where two different scenarios are considered depending on the types of communication channels between the legitimate source and the receiver. We further allow entanglement assistance from the quantum helper in both scenarios. We characterize the involved quantum resources and derive single-letter expressions of the achievable rate region. The direct coding proofs are based on well-known quantum protocols, the quantum state merging protocol, and the fully quantum Slepian-Wolf protocol, together with the quantum reverse Shannon theorem.
Practices in-between: Norwegian long-term visitors in Mediterranean Spain

ABSTRACT During initial ethnographic fieldwork among Norwegian long-term visitors in the province of Alicante in Spain, these visitors expressed concern about the manner in which they were portrayed in the Norwegian news media, in contrast to their own images as holidaymakers. This problem is partly epistemological, since ‘long-term visitors’ were uncertain about their status and role. For instance, on sightseeing tours, sports events or hiking trips, they were tourists. At other times, for instance, when dealing with local authorities, they saw themselves as different from pure tourists. The Norwegian long-termers stated that their stay in Spain was far more multifaceted than what had been portrayed in the media, that they participated in cultural and social activities, and that they had many points of contact with Spanish society. The Norwegian visitors wondered how a more accurate and multi-vocal image of holidaymakers and long-termers could be represented. The concepts of local knowledge, adaptation and discourse will be used here to problematise this timely topic in tourism research on roles and images. Developing a more comprehensive view of long-term visitors will focus not only on their own situation, but also on their relations with other visitors, the host population, and Spanish authorities.
APOSTOL-EULER POLYNOMIALS OF HIGHER ORDER AND GAUSSIAN HYPERGEOMETRIC FUNCTIONS

The purpose of this paper is to give analogous definitions of Apostol type (see T. M. Apostol [Pacific J. Math. 1 (1951), 161-167]) for the so-called Apostol-Euler numbers and polynomials of higher order. We establish their elementary properties, obtain several explicit formulas involving the Gaussian hypergeometric function and the Stirling numbers of the second kind, and deduce their special cases and applications that lead to the corresponding formulas of the classical Euler numbers and polynomials of higher order.
The Frame Problem and Knowledge-Producing Actions

This paper proposes a solution to the frame problem for knowledge-producing actions. An example of a knowledge-producing action is a sense operation performed by a robot to determine whether or not there is an object of a particular shape within its grasp. The work is an extension of Reiter's solution to the frame problem for ordinary actions and Moore's work on knowledge and action. The properties of our specification are that knowledge-producing actions do not affect fluents other than the knowledge fluent, and actions that are not knowledge-producing only affect the knowledge fluent as appropriate. In addition, memory emerges as a side-effect: if something is known in a certain situation, it remains known at successor situations, unless something relevant has changed. Also, it will be shown that a form of regression examined by Reiter for reducing reasoning about future situations to reasoning about the initial situation now also applies to knowledge-producing actions.
Estimating Total Discharge in the Yangtze River Basin Using Satellite-Based Observations

The measurement of total basin discharge along coastal regions is necessary for understanding the hydrological and oceanographic issues related to the water and energy cycles. However, only the observed streamflow (gauge-based observation) is used to estimate the total fluxes from the river basin to the ocean, neglecting the portion of discharge that infiltrates to underground and directly discharges into the ocean. Hence, the aim of this study is to assess the total discharge of the Yangtze River (Chang Jiang) basin. In this study, we explore the potential response of total discharge to changes in precipitation (from the Tropical Rainfall Measuring Mission—TRMM), evaporation (from four versions of the Global Land Data Assimilation—GLDAS, namely, CLM, Mosaic, Noah and VIC), and water-storage changes (from the Gravity Recovery and Climate Experiment—GRACE) by using the terrestrial water budget method. This method has been validated by comparison with the observed streamflow, and shows an agreement with a root mean square error (RMSE) of 14.30 mm/month for GRACE-based discharge and 20.98 mm/month for that derived from precipitation minus evaporation (P − E). This improvement of approximately 32% indicates that monthly terrestrial water-storage changes, as estimated by GRACE, cannot be considered negligible over Yangtze basin. The results for the proposed method are more accurate than the results previously reported in the literature.
Leveraging Domain-expert Knowledge, Boosting and Deep Learning for Identification of Rare and Complex States

Identification of rare states in complex dynamical systems remains challenging due to data incompleteness and limited success in adopting standard machine learning algorithms for such problems. Although alternatives such as single-example learning (SEL) can learn novel classes from just a few training examples using similarities to reference classes for which large data sets are available, SEL performance quickly deteriorates with decreasing number of available reference classes. Previously, we have shown that with availability of just two broad classes, vector of boosting-ensemble components, discovered in supervised classification learning, provides universal state representation. Analytical models and other domain-expert knowledge can be directly incorporated within such ensemble decomposition learning (EDL) framework reducing requirements for data size. Alternatively, auto-encoders (AE), components of deep learning (DL) frameworks for automatic feature selection and dimensionality reduction, offer unlimited flexibility in discovering robust latent representations. However, AEs require large data sets and unlike boosting are less effective in utilization of existing models. We argue that using EDL vectors as inputs in standard AE architectures allows synergetic combination of the two approaches and discovery of robust state representations even with limited data. The framework is illustrated in the context of personalized medicine application using cardio data from www.physionet. org.
Antibacterial Activity Of Various Extracts From The Fruiting Bodies Of Ganoderma Lucidum Growing At Samanea Saman (Jacq.) Merr) Trunk

Ganoderma sp provides bioactive compounds that claim to posses antibacterial activity. The aim of this research is to know antibacteriall activity of various extract of Ganoderma. Fruiting bodies of Ganoderma were extracted by maceration method using 50 % aceton, 50 % ethanol, methanol and boiling water, respectively. Antibacterial activities were done against Staphylococcus aureus and Pseudomonas aureuginosa using disc diffusion assay. The result showed that the extracts had antibacterial activity and methanolic extract at concentration 500 ug/disc had higher antibacterial activity than ethanolic, acetonic, and water extract, with diameter of zone inhibition was 13.04 mm.
Regulatory Networks Controlling Nitrogen Sensing and Uptake in Candida albicans

Nitrogen is one of the key nutrients for microbial growth. During infection, pathogenic fungi like C. albicans need to acquire nitrogen from a broad range of different and changing sources inside the host. Detecting the available nitrogen sources and adjusting the expression of genes for their uptake and degradation is therefore crucial for survival and growth as well as for establishing an infection. Here, we analyzed the transcriptional response of C. albicans to nitrogen starvation and feeding with the infection-relevant nitrogen sources arginine and bovine serum albumin (BSA), representing amino acids and proteins, respectively. The response to nitrogen starvation was marked by an immediate repression of protein synthesis and an up-regulation of general amino acid permeases, as well as an up-regulation of autophagal processes in its later stages. Feeding with arginine led to a fast reduction in expression of general permeases for amino acids and to resumption of protein synthesis. The response to BSA feeding was generally slower, and was additionally characterized by an up-regulation of oligopeptide transporter genes. From time-series data, we inferred network interaction models for genes relevant in nitrogen detection and uptake. Each individual network was found to be largely specific for the experimental condition (starvation or feeding with arginine or BSA). In addition, we detected several novel connections between regulator and effector genes, with putative roles in nitrogen uptake. We conclude that C. albicans adopts a particular nitrogen response network, defined by sets of specific gene-gene connections for each environmental condition. All together, they form a grid of possible gene regulatory networks, increasing the transcriptional flexibility of C. albicans.
Dynamic Portfolio Choice and Risk Aversion

This chapter presents a theory of optimal lifetime consumption-portfolio choice in a continuous information setting, with emphasis on the modeling of risk aversion through generalized recursive utility. A novel contribution is a decision theoretic development of the notions of source-dependent firstor second-order risk aversion. Backward stochastic differential equations (BSDEs) are explained heuristically as continuous-information versions of backward recursions on an information tree, and are used to formulate utility functions as well as optimality conditions. The role of scale invariance and quadratic BSDEs in obtaining tractable solutions is explained. A final section outlines extensions, including optimality conditions under trading constraints, and tractable formulations with nontradeable income.
EMT-induced metabolite signature identifies poor clinical outcome

Metabolic reprogramming is a hallmark of cancer. Epithelial-mesenchymal transition (EMT) induces cancer stem cell (CSC) characteristics and promotes tumor invasiveness; however relatively little is known about the metabolic reprogramming in EMT. Here we show that breast epithelial cells undergo metabolic reprogramming following EMT. Relative to control, cell lines expressing EMT transcription factors show ≥1.5-fold accumulation of glutamine, glutamate, beta-alanine and glycylleucine as well as ≥1.5-fold reduction of phosphoenolpyruvate, urate, and deoxycarnitine. Moreover, these metabolic alterations were found to be predictive of overall survival (hazard ratio = 2.3 (95% confidence interval: 1.31–4.2), logrank p-value = 0.03) and define breast cancer molecular subtypes. EMT-associated metabolites are primarily composed of anapleurotic precursors, suggesting that cells undergoing EMT have a shift in energy production. In summary, we describe a unique panel of metabolites associated with EMT and demonstrate that these metabolites have the potential for predicting clinical and biological characteristics associated with patient survival.
Duration of Intrapartum Antibiotics for Group B Streptococcus on the Diagnosis of Clinical Neonatal Sepsis

Background. Infants born to mothers who are colonized with group B streptococcus (GBS) but received <4 hours of intrapartum antibiotic prophylaxis (IAP) are at-risk for presenting later with sepsis. We assessed if <4 hours of maternal IAP for GBS are associated with an increased incidence of clinical neonatal sepsis. Materials and Methods. A retrospective cohort study of women-infant dyads undergoing IAP for GBS at ≥37-week gestation who presented in labor from January 1, 2003 through December 31, 2007 was performed. Infants diagnosed with clinical sepsis by the duration of maternal IAP received (< or ≥4-hours duration) were determined. Results. More infants whose mothers received <4 hours of IAP were diagnosed with clinical sepsis, 13 of 1,149 (1.1%) versus 15 of 3,633 (0.4%), P = . 03. Multivariate logistic regression analysis showed that treatment with ≥4 hours of IAP reduced the risk of infants being diagnosed with clinical sepsis by 65%, adjusted relative risk 0.35, CI 0.16–0.79, and P = . 01. Conclusion. The rate of neonatal clinical sepsis is increased in newborns of GBS colonized mothers who receive <4 hours compared to ≥4 hours of IAP.
Fingerprint authentication and security risks in smart devices

The smartphone market is growing rapidly and enriching our digital lives by instant of information sharing. As smartphone devices contain sensitive data of users, it is very essential to protect this information efficiently. To fulfill this, modern smartphones are adopting fingerprint scanners for biometric authentication. Fingerprint biometric authentication is simple and quick, however, it is vulnerable to attacks as hackers can steel fingerprint biometric data. Therefore, a consistent fingerprint biometric authentication mechanism is required to protect personal information of the user as well as biometrics data. In this paper, we will analyze different attacks and security risks associated with fingerprint authentication. Previously, there are eight levels of attacks studied to compromise biometric data. Here, we propose two additional levels of attacks to provide a more robust mechanism to deal with security vulnerabilities in future.
IP OVER DVB: MANAGEMENT OF SELF-SIMILARITY

IP OVER DVB: MANAGEMENT OF SELF-SIMILARITY Digital Video Broadcasting (DVB) defines the carriage of multimedia information to clients by means of MPEG-2 Transport Streams (TS). Multimedia information, due to coding and compression, is variable bit rate (VBR) in nature. Furthermore it displays burstiness on different time scales. Due to its bursty nature, VBR video requires more bandwidth than its mean bit rate. Stuffing bits are inserted into the TS to make TS constant bit-rate. In this thesis, we propose a system, which makes use of the wasted bandwidth, due to stuffing bits in MPEG-2 TS, by carrying best-effort IP traffic with the prioritized video traffic. We investigate the statistical properties of the traffic on the proposed network. We give a detailed description for the traffic characteristics, i.e., self-similarity and long-range dependence. We use the NS simulator to simulate the proposed system for different network resource configurations, i.e., bottleneck bandwidth, buffer size, and different traffic characteristics, i.e., self-similarity (Hurst parameter). Analyzing the results, we suggest a bandwidth-driven network resource allocation policy, assuming a fixed overall traffic demand, since it improves both throughput and queuing delay.
