Impact of ship emissions on the microphysical, optical and radiative properties of marine stratus: a case study

Modifications of existing clouds by the exhaust of ships are well-known but inadequately quantified impacts, which could contribute to climate change. The perturbation of a cloud layer by ship-generated aerosol changes the cloud reflectivity and is identified by long curves in satellite im- ages, known as ship tracks. As ship tracks indicate a pollu- tion of a very clean marine environment and also affect the radiation budget below and above the cloud, it is important to investigate their radiative and climatic effects. Satellite- data from MODIS on Terra are used to examine a scene from 10 February 2003 where ship tracks were detected close to the North American West-Coast. The cloud optical and mi- crophysical properties are derived using a semi-analytical re- trieval technique combined with a look-up-table approach. An algorithm is presented to distinguish ship-track-pixels from the unperturbed cloud pixels in the scene and from this the optical properties of the former are compared to those of the latter. Within the ship tracks a significant change in the droplet number concentration, the effective radius and the optical thickness are found compared to the unaffected cloud. The resulting cloud properties are used to calculate the radiation budget below and above the cloud. Assuming a mean solar zenith angle of 63 for the selected scene, the mean solar surface radiation below the ship track is decreased by 43.2 Wm 2 and the mean reflectance at top of atmosphere (TOA) is increased by 40.8 Wm 2 . For the entire analyzed scene the ship emission decreases the solar radiation at the surface by 2.1 Wm 2 and increases the backscattered solar radiation at TOA by 2.0 Wm 2 , whereas no significant effect on thermal radiation was detected.
Quality aspects in service ecosystems: areas for exploitation and exploration

Service Science, Management, and Engineering (SSME) is a research area with significant relevance to research and practice. Networked systems of web services are a field of service science that enjoys growing interest from researchers. The complex and dynamic environment of these service ecosystems poses new requirements on quality management that are insufficiently addressed by current approaches that focus mainly on the technical aspects of quality. This focus is a severe limitation for the development of service networks because it neglects perceived service quality from the viewpoint of service consumers. In this paper we propose a reference model for quality management in service ecosystems. This reference model is linked in particular to innovation and new service development. Towards the end we propose premises for the implementation and outline a future research agenda.
Optimal Triangulation in 3 D Computer Vision Using a Multi-objective Evolutionary Algorithm

The triangulation is a process by which the 3D point position can be calculated from two images where that point is visible. This process requires the intersection of two known lines in the space. However, in the presence of noise this intersection does not occur, then it is necessary to estimate the best approximation. One option towards achieving this goal is the usage of evolutionary algorithms. In general, evolutionary algorithms are very robust optimization techniques, however in some cases, they could have some troubles finding the global optimum getting trapped in a local optimum. To overcome this situation some authors suggested removing the local optima in the search space by means of a single-objective problem to a multi-objective transformation. This process is called multi-objectivization. In this paper we successfully apply this multi-objectivization to the triangulation problem.
Acute Renal Endothelial Injury During Marrow Recovery in a Cohort of Combined Kidney and Bone Marrow Allografts

An idiopathic capillary leak syndrome (‘engraftment syndrome’) often occurs in recipients of hematopoietic cells, manifested clinically by transient azotemia and sometimes fever and fluid retention. Here, we report the renal pathology in 10 recipients of combined bone marrow and kidney allografts. Nine developed graft dysfunction on day 10–16 and renal biopsies showed marked acute tubular injury, with interstitial edema, hemorrhage and capillary congestion, with little or no interstitial infiltrate (≤10%) and marked glomerular and peritubular capillary (PTC) endothelial injury and loss by electron microscopy. Two had transient arterial endothelial inflammation; and 2 had C4d deposition. The cells in capillaries were primarily CD68+MPO+ mononuclear cells and CD3+CD8+ T cells, the latter with a high proliferative index (Ki67+). B cells (CD20+) and CD4+ T cells were not detectable, and NK cells were rare. XY FISH showed that CD45+ cells in PTCs were of recipient origin. Optimal treatment remains to be defined; two recovered without additional therapy, six were treated with anti‐rejection regimens. Except for one patient, who later developed thrombotic microangiopathy and one with acute humoral rejection, all fully recovered within 2–4 weeks. Graft endothelium is the primary target of this process, attributable to as yet obscure mechanisms, arising during leukocyte recovery.
SUPPRESSION, OPPRESSION, AND SURVIVAL: THE EXPLOITED WORKER IN TONI MORRISON’S JAZZ

Karl Heinrich Marx’s worker loses his identity as he descends to the level of commodity by working like a machine in a capitalist world. Capitalism thrives on exploitation, unemployment and monopoly of the capital. I endeavour to locate how Toni Morrison’s Jazz accentuates the struggle of oppressed members of the black community against firm structures of slavery, feudalism and capitalism. Morrison addresses strain perpetuated on burdened people through exploitation of economy; thus Jazz epitomizes the marginalized section of the society, which is not given equal opportunities to sustain and have no access to wealth and positions of privilege. The dominant class uses power and discourse to make the system appear logical and natural. Analysis is based on examples from the text, which are stylistically worked out and structurally scrutinized. It is an examination of social realities of African-American community which has decided to raise voice against injustice. KEYWORDS: bourgeoisie, capitalism, economic, exploitation, labourer, proletariat
Automated land use identification using cell-phone records

Pervasive large-scale infrastructures generate datasets that contain human behavior info rmation. In this context, cell phones and cell phone networks, due to its pervasiveness, can be considered sensors of human behavior and one of the main elements that define our digital footprint. In this paper we present a technique for the automatic identification and classification of land uses from the information generated by a cell-phone network infrastructure. Our approach first computes the aggregated calling patterns of the antennas of the network and, after that, finds the optimum cluster distribution to automatically identify how citizens use the different geographic regions within a city. We present and validate our results using cell phone records collected for the city of Madrid.
An improved clustering algorithm based on K-means and harmony search optimization

Clustering is a data mining technique that classifies a set of observations into several clusters based on some similarity measures. The most commonly used partitioning based clustering algorithm is K-means. However, the K-means algorithm has several drawbacks. The algorithm generates a local optimal solution based on the randomly chosen initial centroids. A recently developed meta heuristic optimization algorithm named harmony search helps to find out near global optimal solutions by searching the entire solution space. K-means performs a localized searching. Studies have shown that hybrid algorithm that combines the two ideas will produce a better solution. In this paper, a new approach that combines the improved harmony search optimization technique and an enhanced K-means algorithm is proposed.
A Study of Employee Personality's Impact Toward Customer Satisfaction

The purpose of the study was to investigate the employee personality’s impact toward customer satisfaction and how employee personality directly or indirectly influenced the customer satisfaction. Two conceptual mechanisms were employed according to the statements of Five Factor Model (FFM) of personality and Service Quality Model (SERVQUAL). In addition, three elements of impact were found as following:(1) employee personality would have an influence upon employee behavior in turn to customer satisfaction;(2) employee personality would influence employee attitude in turn to customer satisfaction;(3) employee personality has an effect directly on employee performance or indirectly on employee performance via employee behavior or attitude in turn to customer satisfaction. Key word:Five Factor Model, SERVQUAL, Personality, Customer satisfaction
MOLECULAR HYBRIDIZATION TECHNIQUES OF NUCLEIC ACIDS

The nucleic acid hybridization is the process wherein two DNA or RNA single chains (mono-stranded) from different biological sources, make the double catenary configuration, based on contingent sequence homology of the two sources, resulting DNA-DNA, RNA-RNA or DNA-RNA hybrids. The purpose is identification or localization of certain nucleic acid sequences (genes) in the genome of some species. The target molecule representing the DNA, RNA or protein sequence that should be identified or located and the probe molecule who identify the target, by hybridization. Hybridization on a solid carrier is: Southern blotting, Northern blotting, Western blotting. Hybridization stages is: probe synthesis, probe marking (radioactively or non-radioactively), target DNA processing, target DNA denaturation, target DNA transfer to solid carrier, molecular hybridization.
Exploiting underrepresented query aspects for automatic query expansion

Users attempt to express their search goals through web search queries. When a search goal has multiple components or aspects, documents that represent all the aspects are likely to be more relevant than those that only represent some aspects. Current web search engines often produce result sets whose top ranking documents represent only a subset of the query aspects. By expanding the query using the right keywords, the search engine can find documents that represent more query aspects and performance improves. This paper describes AbraQ, an approach for automatically finding the right keywords to expand the query. AbraQ identifies the aspects in the query, identifies which aspects are underrepresented in the result set of the original query, and finally, for any particularly underrepresented aspect, identifies keywords that would enhance that aspect's representation and automatically expands the query using the best one. The paper presents experiments that show AbraQ significantly increases the precision of hard queries, whereas traditional automatic query expansion techniques have not improved precision. AbraQ also compared favourably against a range of interactive query expansion techniques that require user involvement including clustering, web-log analysis, relevance feedback, and pseudo relevance feedback.
Heterologous fermentation of a diterpene from Alternaria brassisicola

A variety of different applications render terpenes and terpenoids attractive research targets. A promising but so far insufficiently explored family of terpenoids are the fusicoccanes that comprise a characteristic 5-8-5 fused tricyclic ring system. Besides herbicidal effects, these compounds also show apoptotic and anti-tumour effects on mammalian cells. The access to fusicoccanes from natural sources is scarce. Recently, we introduced a metabolically engineered Saccharomyces cerevisiae strain to enable the heterologous fermentation of the shared fusicoccane–diterpenoid precursor, fusicocca-2,10(14)-diene. Here, we show experiments towards the identification of bottlenecks in this process. The suppression of biosynthetic by-products via medium optimisation was found to be an important aspect. In addition, the fermentation process seems to be improved under oxygen limitation conditions. Under fed-batch conditions, the fermentation yield was reproducibly increased to approximately 20 mg/L. Furthermore, the impact of the properties of the terpene synthase on the fermentation yield is discussed, and the preliminary studies on the engineering of this key enzyme are presented.
Structured Robust Loop Shaping Control For HIMAT System Using Swarm Intelligent Approach

Robust loop shaping control is a feasible method for designing a robust controller; however, the controller designed by this method is complicated and difficult to implement practically. To overcome this problem, in this paper, a new design technique of a fixed-structure robust loop shaping controller for a highly maneuverable airplane, HIMAT, is proposed. The performance and robust stability conditions of the designed system satisfying H ∞ loop shaping control are formulated as the objective function in the optimization problem. Particle Swarm Optimization (PSO) technique is adopted to solve this problem and to achieve the control parameters of the proposed controller. Simulation results demonstrate that the proposed approach is numerically efficient and leads to performance comparable to that of the other method.
Dust formation in early galaxies

We investigate the sources and amount of dust in early galaxies. We discuss dust nucleation in stellar atmospheres using published extended atmosphere models, stellar evolution tracks and nucleation conditions. The thermally pulsating asymptotic giant branch phase of intermediate-mass stars is likely to be the most promising site for dust formation in stellar winds. We present an elementary model including dust formation time-scales in which the amount of dust in the interstellar medium is governed by chemical evolution. The implications of the model for high-redshift galaxies are investigated and we show there is no difficulty in producing dusty galaxies at redshifts above 5 if supernovae are a dominant source of interstellar dust. If dust does not condense efficiently in supernovae then significant dust masses can only be generated at z > 5 by galaxies with a high star formation efficiency. This is consistent with the high star formation rates implied by submillimetre sources found in deep Submillimetre Common User Bolometric Array surveys. We find the visual optical depth for individual star-forming clouds can reach values greater than 1 at very low metallicity (1/100 solar) provided that the mass–radius exponent of molecular clouds is less than 2. Most of the radiation from star formation will emerge at infrared wavelengths in the early Universe provided that dust is present. The (patchy) visual optical depth through a typical early galaxy will, however, remain less than 1 on average until a metallicity of 1/10 solar is reached.
Forecasting index v olatility : sampling inter v al and non-trading e ff ects

A detailed comparison is made of volatility forecasting techniques on Australian value-weighted indices. The techniques compared are the naı̈ve approach (historical volatility), an improved extreme-value method (IEV), the ARCH/GARCH class of models and an exponentially weighted moving average (EWMA) of volatility. The study suggests that the EWMA technique appears to be the best volatility forecasting technique, closely followed by the appropriate GARCH specification. Both the IEV and historical volatility approaches are poor by comparison. The diversification benefit that arises from indices with larger numbers of stocks appears to make forecasting the volatility of larger indices more accurate. However, as the sampling interval is reduced, the non-trading effects evident in the larger indices start to counteract this benefit.
Collaborative streaming of on demand videos for mobile devices

The 3G and LTE technologies made video on-demand a popular entertainment for users on the go. However, bandwidth insufficiency is an obstacle in providing high quality and smooth video playout in cellular networks. The objective of the proposed PhD research is to provide a user with high quality video streaming with minimal stalling time by aggregating bandwidth from ubiquitous nearby devices that may be using different radio networks.
Life aspirations, values and moral foundations in Mongolian youth

Abstract Life aspirations have aroused much interest in youth studies. Yet, their psychological correlates remain unclear, especially in countries outside the US. The aim of this study was to explore associations among aspirations, values and moral foundations in 157 Mongolian youth, through questionnaires used widely around the world. Correlational and mean differences analyses found that Mongolian youths’ endorsement of intrinsic life aspirations in general was related to self-transcendent values, whereas their endorsement of extrinsic aspirations was related to self-enhancement values. Moral foundations showed fewer relationships to life aspirations. Binding moral foundations (authority and sanctity) contraindicated intrinsic aspirations, but loyalty correlated positively with extrinsic aspirations. Intrinsic aspirations were supported by moral progressivism (domination of individualizing moral foundations over binding moral foundations). As a generally understudied population, these findings provide a foundation for further study of Mongolian youths’ aspirations.
A construction of commutative D-branes from Lower dimensional non-BPS D-branes

We construct an exact soliton, which represents a BPS Dp-brane, in a boundary string field theory action of infinitely many non-BPS D(p−1)-branes. Furthermore, we show that this soliton can be regarded as an exact soliton in the full string field theory. The world-volume theory of the BPS Dp-brane constructed in this way becomes usual gauge theory on commutative p+1, instead of non-commutative plane. We also construct a Dp-brane from non-BPS D(p−n)-branes by the ABS like configuration. We confirm that the Dp-brane has correct RR charges and the tension.
High-dimensional Wavelet Modeling

Wavelets can be thought of as a set of well-localized basis functions with very good approximation properties. The diiculty in applying wavelet approximation to high-dimensional data is that the number of basis functions increases exponentially with the number of dimensions, making the application of standard mathematical methods for determining coeecients diic ult. We propose a modeling methodology that uses multidimensional cubic B-spline wavelets whose co eecients are determined by a nonlinear optimization procedure that combines simulated anneali ng with hill climbing.
Built in self test architecture for testing SRAM using transient current testing

Semiconductor memories most specifically Static Random Access Memories (SRAMs) are becoming very popular in today's System-On-Chip (SOCs). Memories become more susceptible to faults when the complexity of these memories increase as the technology shrinks. In order to detect these faults, March algorithm has been widely used. This detection of faults in SRAM has been a time consuming process. Hence transient current testing (IDDT) methods are used. This paper implements a transient current testing method to detect faults in Complementary Mosfet (CMOS) SRAM cells. By monitoring a transient current pulse during a write operation or a read operation, faults can be detected. In order to detect the fault a Built in self test (BIST) circuit is developed. Simulations are carried out on a 6T SRAM circuit, to detect the difference in amplitude of the IDDT waveform. Simulations are also carried out on a 4 *4 SRAM array to detect the occurrence of fault . The SRAM circuit, array circuit and the sensor circuits are designed in I8Onm CMOS technology.
Persistent fetal ocular vasculature in mice deficient in bax and bak.

BACKGROUND The ocular fetal vasculature normally regresses by apoptosis but for unknown reasons fails to regress in the human disease persistent fetal vasculature. OBJECTIVE To investigate whether proapoptotic Bcl-2 members, Bax and Bak, are involved in fetal vasculature regression. METHODS Adult eyes from mice deficient in Bax and/or Bak were examined grossly and histologically for persistence of fetal vasculature. Vessels were identified by the presence of lumens and erythrocytes and by Factor VIII labeling. Eyes from postnatal day 7 mice were processed for terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) analysis to determine if deficiency of Bax and Bak results in defective developmental apoptosis. RESULTS Only bax(-/-)bak(-/-) eyes retained fetal vasculature into adulthood. This vasculature consisted of a hyaloid artery emerging from the optic nerve head and intravitreal and perilental vessels but not a pupillary membrane. At postnatal day 7, wild-type but not bax(-/-)bak(-/-) eyes had TUNEL-positive cells in the fetal vasculature. CONCLUSIONS These data demonstrate that Bax and Bak serve overlapping functions in fetal vasculature regression, emphasizing the importance of apoptosis in developmental remodeling. Clinical Relevance Disruption of Bax and Bak results in persistent fetal vasculature in knockout mice, providing a model of the human disease persistent fetal vasculature to investigate its etiology and potential therapies.
Rattan Isobaric Vapor-Liquid Equilibrium of Binary Mixture of Methyl Acetate with Isopropylbenzene at 97 . 3 kPa P

Isobaric vapor-liquid equilibrium measurements are reported for the binary mixture of Methyl acetate and Isopropylbenzene at 97.3 kPa. The measurements have been performed using a vapor recirculating type (modified Othmer's) equilibrium still. The mixture shows positive deviation from ideality and does not form an azeotrope. The activity coefficients have been calculated taking into consideration the vapor phase nonideality. The data satisfy the thermodynamic consistency tests of Herington and Black. The activity coefficients have been satisfactorily correlated by means of the Margules, NRTL, and Black equations. A comparison of the values of activity coefficients obtained by experimental data with the UNIFAC model has been made. Keywords—Binary mixture, Isopropylbenzene, Methyl acetate, Vapor-liquid equilibrium.
A Serious Game using Physiological Interfaces for Emotion regulation Training in the Context of Financial Decision-Making

Abstract Research on financial decision-making shows that traders and investors with high emotion regulation capabilities perform better in trading. But how can the others learn to regulate their emotions? ‘Learning by doing’ sounds like a straightforward approach. But how can one perform ‘learning by doing’ when there is no feedback? This problem particularly applies to learning emotion regulation, because learners can get practically no feedback on their level of emotion regulation. Our research aims at providing a learning environment that can help decision-makers to improve their emotion regulation. The approach is based on a serious game with real-time biofeedback. The game is settled in a financial context and the decision scenario is directly linked to the individual biofeedback of the learner’s heart rate data. More specifically, depending on the learner’s ability to regulate emotions, the decision scenario of the game continuously adjusts and thereby becomes more (or less) difficult. The learner wears an electrocardiogram sensor that transfers the data via Bluetooth to the game. The game itself is evaluated at several levels. Keywords: Serious Games, Emotion Regulation, Biofeedback.
