description: Phagocytosis is the defining feature of professional phagocytes of the innate immune system. This function is typically carried out by phagocytic receptors on the cell surface. These receptors can mediate binding and engulfment of solid particles. However, these phagocytic receptors have evolved very recently in history comparing to phagocytosis as a conserved cellular function. This suggests a primordial form of phagocytosis might exist. Years ago, our laboratory uncovered an expected phagocytic mechanism that solid particle can bind to membrane lipids on phagocytes to trigger lipid sorting. Consequently, this can lead to phagocytosis akin to FcγR-based phagocytosis regarding its dependence on Immunoreceptor Tyrosine-based Activation Motif (ITAM), Src-family kinases, Syk, and phosphoinositide 3-kinase (PI3K). Based on these findings, we proposed a hypothetical mechanism for solid particle phagocytosis termed “Signaling Equivalent Platform” (SEP). In short, membrane engagement with solid structures, either via ligand/receptor binding or merely being stabilized by an approaching solid surface will lead to a shared downstream pathway with the same dependence on ITAM and Syk. Both modes of phagocytosis are equivalent for its activation by solid structures. However, the identity of the ITAM-containing molecule and the exact involvement of lipid during solid particle phagocytosis under SEP is still unclear. This thesis serves to strengthen the idea of SEP by identifying the ITAM-containing molecule and further characterizing the involvement of the ITAM-containing molecule and lipids during solid particle phagocytosis. We used a generic ITAM sequence as a probe and identified moesin as the ITAM-containing molecule from the mouse genome. We further demonstrated that a solid structure binding to the cell surface leads to autonomous accumulation of phosphatidylinositol 4, 5-bisphosphate (PIP2) to the site of contact, which attracts moesin, a conserved structural linker, to the plasma membrane. Moreover, Moesin, via its ITAM, is sufficient to activate phagocytic programming including Syk and downstream signaling that is virtually identical to that initiated by Fcγ receptors. Bioinformatic analysis suggested that this moesin-mediated signaling predates modern Fcγ and immune receptors. This thesis, therefore, reveals an evolutionarily conserved moesin-, PIP2-mediated signaling platform for the evolutionarily conserved phagocytosis that provides essential components for modern ITAM-based signaling cascades.
Harnessing the community capacity of small farmer organizations to reduce pesticide-related environmental health risks : a case study in an indigenous community in the southern ranges of Ecuador, 2007-2008
Creators: name: Cabarcas, Fabio

description: This work aims to better understand the capacity of small farmers, their organizations and other social players in the Ecuadorian indigenous communities of Quilloac and San Rafael to reduce pesticide-related environmental health risks. I used a multi-method approach that included Pierre Bourdieu’s field theory along with a 187-household survey, ethnographic methods, and participative approaches in 2007-2008. This study analyzed community capacity-building as social relationships co-determined by human agency and social structure in local and global contexts. By mapping community stakeholders’ differential access to cultural, social and economic capital, this study reveals connections between the degree of access to resources and health vulnerabilities. Four key findings emerged. First, in a context in which workers were forced to diversify their income through strategies such as emigration and urban employment, families had reduced time for their crops and increased reliance on pesticides. Members of households with fewer people applied pesticides more times. Elders from poor households were left to care for crops and experienced more problems with pesticide handling and symptoms. Children experienced increases in accidental pesticide poisoning cases that coincided with a period of high farmer migration to find work. Second, despite numerous well-intended efforts by community leaders, farmers with the highest participation in agriculture had less contact with community organizations. Third, structural factors such as inequitable land distribution, unfavorable market policies, and limited state support for small farmers represent critical barriers for harnessing the capacity of small farmer organizations. Fourth, community leaders tended to adopt peasantry-focused strategies that were likely to further marginalize some vulnerable families who combined non-agricultural activities with their farming, which was characterized by consumption crops with low workforce and high pesticide use. My findings provide theoretical and practical contributions for understanding the causes of environmental health inequities. Results from this research informed the development of several community-based initiatives (workshops, a radio show). My approach described important contextual barriers that need to be addressed by national and international stakeholders in order to harness the capacity of local organizations. It also identified specific social mechanisms that could increase health inequities despite great efforts by community organizations.

description: Canada has many lakes and rivers, and studying these inland water resources requires information about their water level changes. Until recently, the knowledge of the spatiotemporal variations of continental waters in Canada was limited to in-situ observations and hydrological models. The poor spatiotemporal coverage of tide-gauge stations and the inaccessibility of some inland water surfaces make it difficult to monitor their water level changes. The number of in-situ stations has also dramatically declined in the last few years and, therefore, there is a need to develop alternative methods of continental water level monitoring. Satellite altimetry has the advantages of operating continuously, in all-weather conditions, and can provide data for lake and river level monitoring. In this thesis, the potential of satellite altimetry to determine water level variations over lakes and rivers in Canada is assessed. Altimetry data from the Jason-1, Jason-2, Jason-3, Cryosat-2 and SARAL missions are used to estimate the Water Surface Height (WSH) time series between 2002 and 2017. The estimated multi-mission and single-mission WSH time series are validated against tide-gauge data and their correlation coefficient (R) and RMS differences (D) are estimated. The multi-mission WSH time series over larger water bodies with good data coverage (e.g., Lake Superior) are in excellent agreement (R = 0.98 and D = 4 cm) with tide-gauge data. The ocean-like condition of this lake due to its large size allows satellite altimetry to provide water level data that are not affected a lot by the surrounding topography. As a result, an excellent agreement of altimetry time series with tide-gauge data is achieved. Smaller water bodies (e.g., Lake Athabasca) show lower correlation (R = 0.71) and larger RMS differences (D = 70 cm) between altimetry time series and tide-gauge data. The low correlation and high RMS values are the results of less available WSH data caused by ice coverage during winter over Lake Athabasca. Other studies, e.g., Schwatke et al. (2015), provide better results over Lake Athabasca because of using more altimetry data and better outlier removal methods.

description: The goal is to identify the class of distributions to which the distribution of the maximum of a Lévy process with no negative jumps and negative mean (equivalently, the stationary distribution of the reflected process) belongs. An explicit new distributional identity is obtained for the case where the Lévy process is an independent sum of a Brownian motion and a general subordinator (nondecreasing Lévy process) in terms of a geometrically distributed sum of independent random variables. This generalizes both the distributional form of the standard Pollaczeck-Khinchine formula for stationary workload distribution in the M/G/1 queue and the exponential stationary distribution of a reflected Brownian motion.

A Formal Characterization of Epsilon Serializability
Creators: name: Ramamritham, Krithi
name: Pu, Calton
Publisher: name: Columbia University
Year: 1991
Subjects: Computer science

description: Epsilon Serializability (ESR) is a generalization of classic serializability (SR). ESR allows some limited amount of inconsistency in transaction processing (TP), through an interface called epsilon-transactions (ETs). For example, some query ETs may view inconsistent data due to non-SR interleaving with concurrent updates. In this paper, we restrict our attention to the situation where query-only ETs run concurrently with consistent update transactions that are SR without the ETs. This paper presents a formal characterization of ESR and ETs. Using the ACTA framework, the first part of this characterization formally expresses the inter-transaction conflicts that are recognized by ESR and, through that, defines ESR, analogous to the manner in which conflict-based serializability is defined. The second part of the paper is devoted to deriving expressions for: (1) the inconsistency in the values of data -- arising from ongoing updates, (2) the inconsistency of the results of a query ““ arising from the inconsistency of the data read in order to process the query, and (3) the inconsistency exported by an update ET - arising from ongoing queries reading uncommitted data produced by the update ET. These expressions are used to determine the preconditions that ET operations have to satisfy in order to maintain the limits on the inconsistency in the data read by query ETs, the inconsistency exported by update ETs, and the inconsistency in the results of queries. This determination suggests possible mechanisms that can be used to realize ESR.

description: In the present paper we consider the motion of a very heavy tracer particle in a medium of a very dense, non-interacting Bose gas. We prove that, in a certain mean-field limit, the tracer particle will be decelerated and come to rest somewhere in the medium. Friction is caused by emission of Cerenkov radiation of gapless modes into the gas. Mathematically, a system of semilinear integro-differential equations, introduced in [FSSG10], describing a tracer particle in a dispersive medium is investigated, and decay properties of the solution are proven. This work is an extension of [FGS10]; it is an extension because no weak coupling limit for the interaction between tracer particle and medium is assumed. The technical methods used are dispersive estimates and a contraction principle.

description: It has been well recognized that channel state information (CSI) feedback is of great importance for dowlink transmissions of closed-loop wireless networks. However, the existing work typically researched the CSI feedback problem for each individual mobile station (MS), and thus, cannot efficiently model the interactions among self-interested mobile users in the network level. To this end, in this paper, we propose an alternative approach to investigate the CSI feedback rate control problem in the analytical setting of a game theoretic framework, in which a multiple-antenna base station (BS) communicates with a number of co-channel MSs through linear precoder. Specifically, we first present a non-cooperative feedback-rate control game (NFC), in which each MS selects the feedback rate to maximize its performance in a distributed way. To improve efficiency from a social optimum point of view, we then introduce pricing, called the non-cooperative feedback-rate control game with price (NFCP). The game utility is defined as the performance gain by CSI feedback minus the price as a linear function of the CSI feedback rate. The existence of the Nash equilibrium of such games is investigated, and two types of feedback protocols (FDMA and CSMA) are studied. Simulation results show that by adjusting the pricing factor, the distributed NFCP game results in close optimal performance compared with that of the centralized scheme.

description: A liquidity-constrained entrepreneur needs to raise capital to finance a business activity that may cause injuries to third parties - the tort victims. Taking the level of borrowing as fixed, the entrepreneur finances the activity with senior (secured) debt in order to shield assets from the tort victims in bankruptcy. Interestingly, senior debt serves the interests of society more broadly: it creates better incentives for the entrepreneur to take precautions than either junior debt or outside equity. Unfortunately, the entrepreneur will raise a socially excessive amount of senior debt, reducing his incentives for care and generating wasteful spending. Giving tort victims priority over senior debtholders in bankruptcy prevents over-leveraging but leads to suboptimal incentives. Lender liability exacerbates the incentive problem even further. A Limited Seniority Rule, where the firm may issue senior debt up to an exogenous limit after which any further borrowing is treated as junior to the tort claim, dominates these alternatives. Shareholder liability, mandatory liability insurance and punitive damages are also discussed.
Securing Land and Land Transactions in Accra: Land Registration and Off-Register Strategies. The Case of Oyibi and Dansoman

description: This doctoral thesis develops theory to explain how landholders secure their land and land transactions and why they use or do not use land registration and off-register land-securing strategies in urban and peri-urban Accra, the capital city of Ghana. This study argues that without understanding the underlying reasons why landholders choose to use land registration systems or off-register strategies to secure their land, it is difficult to target aspects of the land registration system to improve; nor can feasible alternative(s) be developed. Using semi-structured interviews, data for the research include a total of 81 interviews, a workshop and two focus-group discussions from Oyibi and Dansoman which are, respectively, urban and peri-urban communities in Accra. The data collected is analyzed using a land-securing theoretical framework developed in the context of the on-going changes in the land tenure system, drawing upon the Reasoned Action Approach, Technology Acceptance Model, and a Social Change Model. The study revealed the predominant mode of land-securing behaviour follows a waterfall or staircase trajectory, where land-securing behaviours are determined by perceptions of tenure security and escalated in response to the perceived nature of threat to their claim. The theory that emerged from the analysis holds that landholders evaluate many inter-related causal factors that are dialectical and mutually inclusive when choosing a land-securing strategy. In a socially, politically, and economically precarious environment where tenure is highly insecure and entrepreneurial and exploitative activities abound, landholders evaluate their personal beliefs about consequential outcomes, usefulness, accessibility, and ease of use, together with societal norms, and associated factors which they believe could hinder or facilitate the performance of the land-securing behaviour. Additionally, landholders also evaluate the degree of security of their tenure or transactions and the level of threat they face. This research deepens understanding of land registration usage through the development of theories that explain why landholders do not use land registration in securing land in urban and peri-urban Accra, by constructing a waterfall and staircase model for explaining land-securing strategy usage. Results from the study are useful for improving current (or developing alternative) approaches for securing land rights in Ghana.

description: We report the fusion of photons from two independent photonic crystal fiber sources into polarization entangled states using a fiber-based polarizing beam splitter. We achieve fidelities of up to F = 0.74 $\pm$ 0.01 with respect to the maximally entangled Bell state ϕ+ using a low pump power of 5.3mW with a success rate of 3.2 four-fold detections per second. By increasing the pump power we find that success rates of up to 111.6 four-folds per second can be achieved, with entanglement still present in the fused state. We characterize the fusion operation by providing a full quantum process reconstruction. Here a model is developed to describe the generation of entanglement, including the main causes of imperfection, and we show that this model fits well with the experimental results. Our work shows how non-ideal settings limit the success of the fusion, providing useful information about the practical requirements for an operation that may be used to build large entangled states in bulk and on-chip quantum photonic waveguides.

description: Using fits to numerical simulations, we show that the entire hierarchy of moments quickly ceases to provide a complete description of the convergence one-point probability density function leaving the linear regime. This suggests that the full N-point correlation function hierarchy of the convergence field becomes quickly generically incomplete and a very poor cosmological probe on nonlinear scales. At the scale of unit variance, only 5% of the Fisher information content of the one-point probability density function is still contained in its hierarchy of moments, making clear that information escaping the hierarchy is a far stronger effect than information propagating to higher order moments. It follows that the constraints on cosmological parameters achievable through extraction of the entire hierarchy become suboptimal by large amounts. A simple logarithmic mapping makes the moment hierarchy well suited again for parameter extraction.

description: The process comparing the empirical cumulative distribution function of the sample with a parametric estimate of the cumulative distribution function is known as the empirical process with estimated parameters and has been extensively employed in the literature for goodness-of-fit testing. The simplest way to carry out such goodness-of-fit tests, especially in a multivariate setting, is to use a parametric bootstrap. Although very easy to implement, the parametric bootstrap can become very computationally expensive as the sample size, the number of parameters, or the dimension of the data increase. An alternative resampling technique based on a fast weighted bootstrap is proposed in this paper, and is studied both theoretically and empirically. The outcome of this work is a generic and computationally efficient multiplier goodness-of-fit procedure that can be used as a large-sample alternative to the parametric bootstrap. In order to approximately determine how large the sample size needs to be for the parametric and weighted bootstraps to have roughly equivalent powers, extensive Monte Carlo experiments are carried out in dimension one, two and three, and for models containing up to nine parameters. The computational gains resulting from the use of the proposed multiplier goodness-of-fit procedure are illustrated on trivariate financial data. A by-product of this work is a fast large-sample goodness-of-fit procedure for the bivariate and trivariate t distribution whose degrees of freedom are fixed.

Based on this definition, we analyze the information loss in static input-output systems subject to a continuous-valued input. For a certain class of multiple-input, multiple-output systems the information loss is quantified. An interpretation of this loss is accompanied by upper bounds which are simple to evaluate. Finally, a class of systems is identified for which the information loss is necessarily infinite. Quantizers and limiters are shown to belong to this class.

description: CLASP (CLAssification of Scenarios and Plans) is a knowledge representation system that extends the notion of subsumption from terminological languages to plans. The CLASP representation language provides description-forming operators that specify temporal and conditional relationships between actions represented in CLASSIC (a current subsumption-based knowledge representation language). CLASP supports subsumption inferences between plan concepts and other plan concepts, as well as between plan concepts and plan instances. These inferences support the automatic creation of a plan taxonomy. Subsumption in CLASP builds on term subsumption in CLASSIC and illustrates how term subsumption can be exploited to serve special needs. In particular, the CLASP algorithms for plan subsumption integrate work in automata theory with work in term subsumption. We are using CLASP to store and retrieve information about feature specifications and test scripts in the context of a large software development project.

description: Using copulas to model the stochastic dependence of values, this paper establishes new general conditions on the profitability of product bundling. A multiproduct monopolist generally achieves higher profit from mixed bundling than from separate selling if consumer values for two products are negatively dependent, independent, or have limited positive dependence. With more than two goods, the same conditions are sufficient for an optimal monopoly selling scheme to include a bundle of at least two products. The profitability of monopoly bundling also extends to situations where a multiproduct firm competes with a single-product rival.

The role of lockups in takeover contests

Publisher: name: Columbia University
Year: 2006
Subjects: Economics

description: This paper examines breakup fees and stock lockups as devices for prospective target firms to encourage bidder participation in takeover contest. We show that, unless bidding costs for the first bidder are too high, breakup fees provide for the socially desirable degree of competition and ensure the efficient allocation of the target to the highest valued buyer in a takeover auction. In contrast, stock lockups permit the target firm to subsidize entry of a new bidder at the expense of an incumbent bidder. Stock lockups induce too much competition when offered to a second bidder and too little competition when offered to a first bidder. Despite their socially wasteful properties, target management would favor stock lockups as they induce takeover competition at least cost to the target.

description: Santa market is a traditional market located in Jakarta, Indonesia. It is generally understood as a commercial retail place for trading and market activities of household goods and services. Yet, following its 30 years oflife and evolution, Santa can be regarded as more than a place for satisfying the needs and wants by means of shopping. For some users who spend longer hours at the market such as the merchants, Santa had grown into a place for working and temporary living. Thus, the market users, the time spent and the activities during their time at the market have become the main concern addressed in this MDP. Daily activities performed within seven to fifteen hours spent at the market by the merchants have become as important as the main trading and market activities. Moreover, the additional presence of family and relatives of the merchants at the market has temporarily shifted the family life into the market and has contributed to the shaping of the Market life. This MDP accommodates the co-existence between the market activities performed by the merchants and the shoppers and the daily activities performed by the merchants and their relatives as they are important aspects that create the Market life and its dynamics. This MDP proposes an alternative design for the renovation program of Santa, for consideration by the Jakarta Market Authority and for the future design of traditional markets in Indonesia.

description: CFDP is a protocol that takes advantage of the broadcast nature of CSMA networks to speed up simultaneous one-to-many file transfers (e.g., when booting diskless workstations). The CFDP server listens and services requests for entire files or portions thereof. CFDP clients first determine whether the file they are interested in is already being transferred, in which case they "eavesdrop" and load as much of it as they can, or they initiate a new transfer. The clients timeout when the server stops transmitting, and if they are still missing parts of the file they request them with a block-transfer request. CFDP is a back-end protocol a front end is needed to handle naming and security issues. A simple such front end is also presented here.

Good Jobs, Bad Jobs, and the Great Recession: Lessons from Japan’s Lost Decade

description: This paper provides novel evidence on the long-term effect of the Great Recession on the quality of jobs, in particular whether the Great Recession results in the replacement of “good jobs” (characterized by high wage/benefit, job security, and opportunity for training and development) with “bad jobs” (characterized by the lack of such attributes). Unfortunately there is not yet sufficiently long data from the recent Great Recession that enable researchers to study fully its long-term consequences for the labor market structure. To this end, we examine Japan’s Lost Decade, the original Great Recession that occurred two decades ago. First, we find no evidence for a shift of male employment toward “bad jobs” during the Lost Decade. Second, for women we find a compositional change from self-employment to nonstandard employment which is, however, found to be a shift from “bad jobs” to “bad jobs” rather than “good jobs” to “bad jobs”. As such, our findings cast doubt on the popular narrative of the long-term negative effect on job quality of the Great Recession. However, for one particular group of Japanese workers—youth, we find compelling evidence in support of the popular narrative. Especially all progresses that young women made in enhancing their share of standard employment during Japan’s high growth decade in the 1980s are found to be entirely undone during the Lost Decade. The Great Recession affects the quantity of jobs and policy makers ought to pay immediate attention to such quantity effects. However, the Great Recession may also have more long-term structural effects on the quality of jobs, and such long-term effects may be heterogeneous, concentrating on a specific group of workers such as youth.

description: We examine the interactions between different institutional arrangements in a general equilibrium model of a modernizing economy. There is a modern sector, where productivity is high but information asymmetries are large, and a traditional sector where productivity is low but information asymmetries are low. Consequently, agency costs in the modern sector make consumption lending difficult, while such loans are readily obtainable in the traditional sector. The resulting trade-off between credit availability and productivity implies that not everyone will move to the modern sector. In fact, the laissex-fair level of modernization may fail to maximize net social surplus. This situation may also hold in the long run: in a dynamic version of the model, a "trickle-down" effect links the process of modernization with reduction in modern sector agency costs. This effect may be too weak and the economy may get stuck in a trap and never fully modernize. The two-sector structure also yields a natural testing ground for the Kuznets inverted-U hypothesis: we show that even within the "sectoral shifting" class of models, this phenomenon is not robust to small changes in model specification.

description: Naive dimensional analysis (NDA) is a widely used ansatz to estimate coupling constants among composite states emerging from dynamics of a strongly coupled gauge theory. However, the validity of NDA is still unclear because of the difficulty in calculating these quantities in strongly coupled theories. We examine the NDA ansatz using gauge/string duality, by estimating glueball coupling constants from gravitational description. The NDA scaling rule for coupling constants of some types of glueballs is verified and extended by both generic estimation and numerical calculations. The scaling rule verified in this article can be applied to some class of quiver gauge theories as well, not just to gauge theories with a single gauge group $SU(N_c)$.

description: In this paper we continue our systematic study of form factors of half-BPS operators in N=4 super Yang-Mills. In particular, we extend various techniques known for amplitudes to the case of form factors, including MHV rules, recursion relations, unitarity and dual MHV rules. As an application, we present the solution of the recursion relation for split-helicity form factors. We then consider form factors of the stress-tensor multiplet operator and of its chiral truncation, and write down supersymmetric Ward identities using chiral as well as non-chiral superspace formalisms. This allows us to obtain compact formulae for families of form factors, such as the maximally non-MHV case. Finally we generalise dual MHV rules in dual momentum space to form factors.

description: Domain specific texts often have implicit rules on content and organization. We introduce a novel method for synthesizing this topical structure. The system uses corpus examples and recursively merges their topics to build a hierarchical tree. A subjective cross domain evaluation showed that the system performed well in combining related topics and in highlighting important ones.

description: The evolution of the Schottky barrier height (SBH) of Er silicide contacts to n-Si is investigated as a function of the annealing temperature. The SBH is found to drop substantially from 0.43 eV for the as-deposited sample to reach 0.28 eV, its lowest value, at 450 C. By x-ray diffraction, high resolution transmission electron microscopy, and x-ray photoelectron spectroscopy, the decrease in the SBH is shown to be associated with the progressive formation of crystalline ErSi2-x.
Quantum storage of polarization qubits in birefringent and anisotropically absorbing materials

description: Storage of quantum information encoded into true single photons is an essential constituent of long-distance quantum communication based on quantum repeaters and of optical quantum information processing. The storage of photonic polarization qubits is, however, complicated by the fact that many materials are birefringent and have polarization-dependent absorption. Here we present and demonstrate a simple scheme that allows compensating for these polarization effects. The scheme is demonstrated using a solid-state quantum memory implemented with an ensemble of rare-earth ions doped into a biaxial yttrium orthosilicate ($Y_2SiO_5$) crystal. Heralded single photons generated from a filtered spontaneous parametric downconversion source are stored, and quantum state tomography of the retrieved polarization state reveals an average fidelity of $97.5 \pm 0.4%$, which is significantly higher than what is achievable with a measure-and-prepare strategy.

Extracting Context To Improve Accuracy For HTML Content Extraction

description: Web pages contain clutter (such as ads, unnecessary images and extraneous links) around the body of an article, which distracts a user from actual content. Extraction of 'useful and relevant' content from web pages has many applications, including cell phone and PDA browsing, speech rendering for the visually impaired, reducing noise for information retrieval systems and to generally improve the web browsing experience. In our previous work [16], we developed a framework that employed an easily extensible set of techniques that incorporated results from our earlier work on content extraction [16]. Our insight was to work with DOM trees, rather than raw HTML markup. We present here filters that reduce human involvement in applying heuristic settings for websites and instead automate the job by detecting and utilizing the physical layout and content genre of a given website. We also present work we have done towards improving the usability and performance of our content extraction proxy as well as the quality and accuracy of the heuristics that act as filters for inferring the context of a webpage.
