Procesamiento digital de imágenes implementado en LabVIEW para sistemas biológicos y nanomateriales

Images have been used for several decades as a tool for the identification or quantification of certain physical properties. In the field of medicine, they have been applied for the identification of malformations, tumors, fractures, among others. The algorithms implemented in this work are: opening and cutting of image section, filtering operators and pixel quantification. They are used to create a virtual application in the LabVIEW programming environment (LV) as a utility model that applies different algorithms to measure, quantify and determine the differences of changes and shapes in the images that were obtained through a microscope using three different amplifications. In this application, we work with images of cells obtained from the femur of an animal and the quantification of the size distribution of nanomaterials by measuring the individual areas of each cell or particle in the field of vision, in order to show that this application is acceptable.
Spectral model for long‐term computation of thermodynamics and potential evaporation in shallow wetlands

Altiplanic wetlands are unique ecosystems located in the elevated plateaus of Chile, Argentina, Peru, and Bolivia. These ecosystems are under threat due to changes in land use, groundwater extractions, and climate change that will modify the water balance through changes in precipitation and evaporation rates. Long‐term prediction of the fate of aquatic ecosystems imposes computational constraints that make finding a solution impossible in some cases. In this article, we present a spectral model for long‐term simulations of the thermodynamics of shallow wetlands in the limit case when the water depth tends to zero. This spectral model solves for water and sediment temperature, as well as heat, momentum, and mass exchanged with the atmosphere. The parameters of the model (water depth, thermal properties of the sediments, and surface albedo) and the atmospheric downscaling were calibrated using the MODIS product of the land surface temperature. Moreover, the performance of the daily evaporation rates predicted by the model was evaluated against daily pan evaporation data measured between 1964 and 2012. The spectral model was able to correctly represent both seasonal fluctuation and climatic trends observed in daily evaporation rates. It is concluded that the spectral model presented in this article is a suitable tool for assessing the global climate change effects on shallow wetlands whose thermodynamics is forced by heat exchanges with the atmosphere and modulated by the heat‐reservoir role of the sediments.
Impacts of Trade Liberalization on Growth and Poverty in Ethiopia: Dynamic Computable General Equilibrium Simulation Model

To investigate the impacts of trade liberalization in Ethiopia, the paper uses a dynamic Computable General Equilibrium model that allows for quantification of income and welfare effects stemming from tariff reduction. The 1990/2000 Social Accounting Matrix (SAM) is fitted into the model and we simulated alternative policies scenarios depicting full and indiscriminating liberalization, gradual and rationalized liberalization and instantaneous tariff liberalization. The main finding of these scenarios is a decline in poverty among all households in the long run. In the short run, poverty remains significantly unaffected for most of the simulations' scenarios. The simulations' results show that static version of the model underestimates trade liberalization's impacts on production, and welfare, since it excludes the accumulation effects. However, from the alternative simulations' scenarios, instantaneous type of liberalization seems performing well in its capacity to increase real GDP, welfare, real output, and real export in the long run. This liberalization also records substantial decline in poverty level in the long run.
A Review of the Housing Policy in Limpopo Province, South Africa

Abstract Limpopo Province is currently experiencing an acute housing shortage that is exacerbated by the unequal distribution of income in the country and the widening gap between the rich and the poor. Limpopo is alsothe province with the second highest unemployment rate in South Africa. This article analyzes the Department ofCooperative Governance and Traditional Affairs’ (CoGHSTA) implementation of central government’s housingpolicy in all five municipal districts in Limpopo Province and offers recommendations to address housing challenges.It identifies the major problems that hinder the provision of adequate housing, including a shortage of suitablegovernment-owned land for housing and an unreliable Provincial Government database on contractors and suppliersof building material. The negative impact of corruption on the province housing need is also examined. Theresearch study was mainly theoretical, with limited application of empirical research methods. It is recommendedthat zero tolerance towards any form of corruption should be applied in CoGHSTA’s dealings with contractors inthe province.
Decoupling thinking in service operations: a case in healthcare delivery system design

Abstract The notion of decoupling thinking has been well established in the manufacturing operations and supply chain management literature. This paper explores how this decoupling thinking can be applied in service operations and in particular in health care. It first reviews the relevant literature on decoupling fundamentals, the front- and back-office distinction, and new emerging decoupling thinking in service operations. Subsequently, a flow-based framework including content and process is developed for decoupling thinking in service operations. The framework provides an integrated perspective on customer contact, flow driver and flow differentiation (level of customisation). The framework hence, through flow differentiation, introduces the concept of standardisation versus customisation in a service context. This is followed by a health care case example to illustrate how the framework can be applied. The managerial implications are primarily in terms of a modularised approach to system design and management. The framework offers potential for benchmarking with other service systems as well as with manufacturing systems based on the shared foundation in decoupling thinking. Finally, suggestions are provided for further research opportunities derived from this research.
Driven-dissipative many-body systems with mixed power-law interactions: Bistabilities and temperature-driven nonequilibrium phase transitions

We investigate the nonequilibrium dynamics of a driven-dissipative spin ensemble with competing power-law interactions. We demonstrate that dynamical phase transitions as well as bistabilities can emerge for asymptotic van der Waals interactions, but critically rely on the presence of a slower decaying potential core. Upon introducing random particle motion, we show that a finite gas temperature can drive a phase transition with regards to the spin degree of freedom and eventually leads to mean-field behavior in the high-temperature limit. Our work reconciles contrasting observations of recent experiments with Rydberg atoms in the cold-gas and hot-vapor domain, and introduces an efficient theoretical framework in the latter regime.
Content Controlled Image Representation for Sports Streaming

Content based analysis has traditionally been posed in the context of identifying some material in response to a user query. This paper illustrates that given a content based analysis process that can identify semantic events in a sequence, that sequence can then be changed in various ways. A Motion Keyframe is presented to re-express the viewing of a sequence. The notion of content analysis for control of other media processing engines is introduced. Tennis footage is used to illustrate the ideas since sports in general contains strong contextual information.
Aggregations of brittle stars can provide similar ecological roles as mussel reefs Aggregations of brittle stars can provide similar reefs.

Aggregations brittle stars can provide similar ecological roles as mussel reefs. Abstract 1 Biogenic habitats, such as coral reefs, facilitate diverse communities. In aquatic systems, 2 aggregations of mobile benthic species may play a similar ecological role to that of typically 3 sessile biogenic habitats, however, this has rarely been considered. We quantified the abundance 4 of sessile mussels ( Modiolus modiolus ) and aggregating brittle stars ( Ophiotrix fragilis ) and 5 tested for correlations between the density of mussels (live and dead) and brittle stars each with: 6 1) abundance, biomass, diversity and assemblage structure of associated benthic macrofauna; 7 and 2) percent organic matter of the sediment. We found that the abundance of live M. modiolus 8 was positively associated with the abundance and biomass of macrofauna. The positive 9 association between M. modiolus and macrofauna abundance was further amplified with an 10 increase in brittle stars and a decrease in dead mussel shells. Macrofauna biomass was lower 11 with more dead mussel shells and macrofauna diversity increased with more live M. modiolus 12 and brittle stars. Sediment organic matter was positively related with brittle star density, but not 13 with the abundance of live or dead mussels. The positive relationship between brittle stars and 14 sediment organic matter suggests that brittle stars could enhance rates of benthic-pelagic 15 coupling. Given the importance of understanding the functional role of threatened habitats, it is 16 essential that the underlying community patterns be understood through robust observational 17 studies to then derive testable hypotheses to determine drivers. These findings provide novel 18 insight into the ecological role of aggregations of mobile species, which is essential to prioritize 19 conservation and restoration strategies. 20

High Chern number quantum anomalous Hall phases in single-layer graphene with Haldane orbital coupling

Center for Condensed Matter Sciences, National Taiwan University, Taipei 106, Taiwan(Dated: March 22, 2011)We investigate possible phase transitions among the diﬀerent quantum anomalous Hall (QAH)phases in a zigzag graphene ribbon under the inﬂuence of the exchange ﬁeld. The eﬀective tight-binding Hamiltonian for graphene is made up of the hopping term, the Kane-Mele and Rashbaspin-orbit couplings as well as the Haldane orbital term. We ﬁnd that the variation of the exchangeﬁeld results in bulk gap-closing phenomena and phase transitions occur in the graphene system. Ifthe Haldane orbital coupling is absent, the phase transition between the chiral (anti-chiral) edgestate ν = +2 (ν = −2) and the pseudo-quantum spin Hall state (ν = 0) takes place. Surprisingly,when the Haldane orbital coupling is taken into account, an intermediate QSH phase with twoadditional edge modes appears in between phases ν = +2 and ν = −2. This intermediate phase istherefore either the hyper-chiral edge state of high Chern number ν = +4 or anti-hyper-chiral edgestate of ν = −4 when the direction of exchange ﬁeld is reversed. We present the band structures,edge state wave functions and current distributions of the diﬀerent QAH phases in the system. Wealso report the critical exchange ﬁeld values for the QAH phase transitions.
Flight-path vector symbology in tunnel-in-the-sky displays

The tunnel-in-the-sky display is a viable candidate to become the primary flight display of future aircraft cockpits. The tunnel display shows the flight trajectory to be flown in a synthetic threedimensional world. The synthetic nature of the tunnel display allows the display to be augmented with symbology designed to improve the pilot's performance. An example is the flight-path vector (FPV) symbol that explicitly presents the aircraft direction of motion relative to the world. The paper provides a theoretical discussion regarding the potential benefits of presenting the FPV symbol for the pilot's guidance and control task. Furthermore, it describes an experiment which has been conducted to assess the use of a flight-path vector in the task of following a straight tunnel trajectory.
Computational-based approaches in epigenetic research: Insights from computational tools, mathematical models, and machine learning methods

Understudying epigenetics underlying mechanisms is essential. Studies have indicated functional roles of epigenetic events, including DNA methylation and histone modifications, in human disease, stem cell growth and development, aging, response to environmental stresses, and species evolution. High-throughput sequencing techniques alongside routine experimental approaches have rapidly produced a bulk of data that the major part of them remained unprocessed. To analyze, interpret, and process of these data, availability of efficient computational methods is critical. Epigenetic data analysis is complex and difficult because these data contain multi-layer set of information. The methods implemented to this purpose must be able to handle massive data of experimental works and process the epigenetic layers. Furthermore, the methods must be capable of integrating multiple modifications and their combination effects on chromatin conformational structure and consequently the expression network of genes. In this study, we briefly reviewed challenges in the way of the computational epigenetics, the latest reported methods, and significant biological results derived from Appling computational-based methods on epigenetic data.
Dialect Differences and Social Stratification in a North Indian Village - eScholarship

Dialect Differences and Social Stratification in a North Indian Village 1 JOHN J. GUMPERZ University of California, Berkeley I T IS generally recognized that dialect differences exist in every large speech community. When these differences are minor and do not appreciably affect mutual intelligibility, they are disregarded for most purposes of linguistic description. Areas in which there are no significant linguistic barriers are thus ordinarily said to contain speakers of a single language or dialect. However, detailed studies by dialectologists of the distribution of minor speech variants have shown that these are . not idiosyncratic, as had been assumed by some, but are patterned and socially determined. Leonard Bloomfield postulates a direct relationship between linguistic diversity and the amount of verbal interaction among individual members of a community.2 The model he provides is quite similar to the sociogram of the modern social psychologist. He states: The most important differences of speech within a community are due to differences in the density of communication . Imagine a huge chart with a dot for every speaker in the community and imagine that every time any speaker uttered a sentence, an arrow were drawn into the chart pointing from his dot to the dot representing each one of his hearers. At the end of a given period of time, say 70 years, that chart would show us the density of communication in the community . We believe that the differences in communication are not only personal and individual but that the community is di­ vided into various systems of subgroups, such that the persons within a subgroup speak much more to each other than to persons outside their subgroup . Subgroups are separated by lines of weakness in this net of oral communication. These lines are local, due to mere geographical distribution and non-local or as we say social. If this model is valid, then investigations into the relations of speech dif­ ferences to other types of social interaction should be of great interest to stu­ dents of social structure. Work in this field, however, is still in its beginnings. 3 The first systematic attempts to formulate relationships along the above lines were made by McDavid (1946, 1948, 1951). His data were drawn from the field records of the Linguistic Atlas of the United States, a geographical survey aimed primarily at collecting data for historical studies, but which used a sample drawn from the upper, middle, and lower strata of American society. The distribution of the dialect differences discovered was found to be deter­ mined by social as well as geographical factors. McDavid suggests that these social speech styles reflect what he calls social tensions such as those existing between Negroes and whites, Catholics and non-Catholics, and others in northern industrial communities. The field methods and sampling of the Ling­ uistic Atlas have recently been severly criticized on grounds of reliability and
Hyperbolic Discounting: It's Just Allais Paradox

This paper demonstrates that present bias may be viewed as a systematic violation of expected utility theory. I propose a model in which a well known failure of expected utility captured by the Allais paradox is also equivalent to also a well-known failure of exponential discounting captured by hyperbolic discounting. This result also implies a connection between two well known behavioral regularities, one in intertemporal choice and another in choice under uncertainty.
Generation of strongly coupled plasma using Argon-based capillary discharge lasers

Argon based capillary discharge lasers operate in the extreme ultra violet (EUV) at 46.9 nm with an output of up to 0.5 mJ energy per pulse and up to a 10 Hz repetition rate. Focussed irradiances of up to 1012 W cm-2 are achievable and can be used to generate plasma in the warm dense matter regime by irradiating solid material. To model the interaction between such an EUV laser and solid material, the 2D radiative-hydrodynamic code POLLUX has been modified to include absorption via direct photo-ionisation, a super-configuration model to describe the ionisation dependant electronic configurations and a calculation of plasma refractive indices for ray tracing of the incident EUV laser radiation. A simulation study is presented, demonstrating how capillary discharge lasers of 1.2ns pulse duration can be used to generate strongly coupled plasma at close to solid density with temperatures of a few eV and energy densities up to 1×105 J cm-3. Plasmas produced by EUV laser irradiation are shown to be useful for examining the equation-of-state properties of warm dense matter. One difficulty with this technique is the reduction of the strong temperature and density gradients which are produced during the interaction. Methods to inhibit and control these gradients will be examined.
Diaspora As The Instrument Of Humane Capital

By means of the free movements of production factors in the world economy, countries can easily reach the production factors which their economies lack. Having aroused as an additional factor besides the production factors especially in todayâ€™s age, and being regarded as an important production factor by many academics, information has been an important factor for increasing the growth rate of both developing and developed countries. This enables countries to develop without being dependent on their own production factors. However, developing countries have difficulties in sustaining their growth acceleration because of the problems they have in both finding qualified labor power and accessing technology and capital. For this reason, many developing countries search alternative ways for solving this problem and sustaining their growth trend.When the countries which have reached high growth rates and sustain these rates despite the economical crises are analyzed, it can be observed that many of these countries have based their growth economies on information technologies, and benefit from their Diasporas for developing these technologies. It can easily be seen from the studies that while the countries, especially China and India, which have made important economical progresses in the last 10-15 years, they have get fundamental befits from their diasporas.Many developing countries need humane capital as much as they do capital. While these countries benefit from foreign investors for the capital they need, they cannot find a foreign resource that can provide them with labor power necessary for humane capital. Within this respect, the countries (China, India and South Korea etc.) having Diasporas with qualified labor power, try to provide the humane capital they need from these groups. Many Asian and European countries such as China, India and Israel, have tried to meet their humane capital need by getting benefit from Diaspora members who have developed themselves at engineering, R&D and information technology areas aroused in developed countries.The aim of this study is to show developing countries who have Diasporas in developed countries but cannot make use of this power or are unaware of it such as Turkey and Bosnia and Herzegovina that their Diasporas are alternative resources for humane capital necessary for them to sustain the reached growth trend.
Absenteeism in Remission: Planning, Policy, Culture

It has been estimated that employee absenteeism costs the U.S. economy on the order of $40 billion per year. Not surprisingly, great time and effort has been dedicated to research assessing the causes of employee absenteeism with the obvious goal of reducing its incidence in the workplace. It is argued in this article that much of this effort has been of virtually no practical value to the practicing manager. In fact, the prescriptions that would naturally arise from much of this research would almost certainly land managers in the lap of litigation in federal court. Two promising strategies —attention to absence policy and absence culture—are described in this article. Both have the advantage of practical application as well as a distinguished tradition in reducing absenteeism.
Transitional ideal point models for longitudinal multinomial outcomes

For the analysis of longitudinal data, three families of models are generally distinguished: the marginal, the transitional and the subject-specific family. In this paper, we will propose a transitional model for the analysis of change for a nominal response variable. Such an analysis is often hampered by the dimensionality of the problem. We use multidimensional scaling techniques, more specifically the ideal point model, in order to reduce the dimensionality. The model can handle pure transitional data but also allows for explanatory variables. Two empirical examples will be discussed in order to illustrate all the virtues of the model.
