Query on Knowledge Graphs with Hierarchical Relationships
Creators: name: Liu, Kaihua
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: The dramatic popularity of graph database has resulted in a growing interest in graph queries. Two major topics are included in graph queries. One is based on structural relationship to find meaningful results, such as subgraph pattern match and shortest-path query. The other one focuses on semantic-based query to find question answering from knowledge bases. However, most of these queries take knowledge graphs as flat forms and use only normal relationship to mine these graphs, which may lead to mistakes in the query results. In this thesis, we find hierarchical relationship in the knowledge on their semantic relations and make use of hierarchical relationship to query on knowledge graphs; and then we propose a meaningful query and its corresponding efficient query algorithm to get top-k answers on hierarchical knowledge graphs. We also design algorithms on distributed frameworks, which can improve its performance. To demonstrate the effectiveness and the efficiency of our algorithms, we use CISCO related products information that we crawled from official websites to do experiments on distributed frameworks.

Recursive Properties of srdc Structures in Golden Age Musical Theater Songs
Creators: name: Markel, Morgan
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: The srdc is a four-part phrase pattern in popular music consisting of four formal functions: statement (s), restatement (r), departure (d), and conclusion (c). In recent scholarship, the applicability and scope of the four-part pattern has been vigorously debated. The question of whether entire song forms, such as the AABA and verse–prechorus–chorus song forms, can be interpreted as large-scale SRDC patterns has become a primary topic of interest among popular music scholars. In this thesis, I seek to further the argument for the large-scale SRDC reading of the AABA song form by demonstrating the recursive potential of srdc structures in Golden Age musical theater songs. To do so, I survey the characteristic properties of 8- and 16- bar srdc patterns and 32- and 64-bar AABA song forms as they were observed in a corpus study of 89 songs. By highlighting the similar ways in which the srdc’s formal functions are expressed at multiple levels of structure within the surveyed 32- and 64-bar AABA song forms, I demonstrate why these song forms can be interpreted as large-scale SRDC patterns.
Chapter 1 introduces this thesis’s primary research question and surveys the relevant literature on the srdc and other related topics. Chapter 2 outlines the steps taken to assemble the corpus of 89 songs and assesses the srdc patterns and AABA song forms contained therein. Chapter 3 then discusses the results of the corpus study. Chapter 4 examines the structural correspondences between the surveyed srdc patterns and AABA song forms, using a model AABA song form that contains three nested srdc patterns. To conclude this thesis, Chapter 4 closes by discussing some avenues for future research.

description: Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical models of inflation and its alternatives. In order to exploit the full cosmological information in galaxy surveys it is necessary to study the matter power spectrum to fully non-linear scales. We therefore study the non-linear clustering in models with superimposed linear and logarithmic oscillations to the primordial power spectrum by running high-resolution dark-matter-only N-body simulations. We fit a Gaussian envelope for the non-linear damping of superimposed oscillations in the matter power spectrum to the results of the N-body simulations for $k \lesssim 0.6\ h/$Mpc at $0 \leq z \leq 5$ with an accuracy below the percent. We finally use this fitting formula to forecast the capabilities of future galaxy surveys, such as Euclid and Subaru, to probe primordial oscillation down to non-linear scales alone and in combination with the information contained in CMB anisotropies.

Perceptions of General and Situational Influence in Predicting Negative Conflict Behavior: The Moderating Role of Attachment Style
Creators: name: Newberg, Amy
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Because of the numerous ways to operationalize power, much of the literature about power in relationships has not been cohesive. However, to understand when and how perceptions of power are associated with behaviors in relationships, multiple conceptualizations of power must be considered along with personal characteristics. The present study tested how perceptions of general power and situational power interact to predict negative behaviors during relationship conflict for people of various attachment orientations. Additionally, we tested if effects remained stable or changed over the early years of marriage. We found that low general and low situational influence did interact to predict less hostility than different combinations of influence, which did not support my hypothesis. Largely, we did not find systematic support that attachment style was a relevant moderator in considering influence and negative conflict behavior, with one interaction between general influence, situational influence, gender, and avoidance as an exception. Finally, we found that the proposed effects did not differ over time.
Efficient Scaling of a Web Proxy Cluster

Publisher: name: University of Massachusetts Amherst
Year: 2017

description: With the continuing growth in network traffic and increasing diversity in web content, web caching, together with various network functions (NFs), has been introduced to enhance security, optimize network performance, and save expenses. In a large enterprise network with more than tens of thousands of users, a single proxy server is not enough to handle a large number of requests and turns to group processing. When multiple web cache proxies are working as a cluster, they talk with each other and share cached objects by using internet cache protocol (ICP). This leads to poor scalability.
This thesis describes the development of a framework that provides the efficient management of a distributed web cache. A controller is introduced into the cluster of proxy servers and becomes responsible for managing objects shared within the cluster. By obtaining a knowledge of global states from the controller, proxy servers that are working in the group do not need to query its neighbors' storage. This reduces traffic in the cluster and saves the computing resources of associated proxy servers. The evaluation on a caching proxy benchmark has shown that our approach demonstrates a superior scalability in comparison to an ICP web caching cluster.

Directed by: Dr. Alayne G. Ronnenberg
High sugar-sweetened beverage (SSB) intake and poor vitamin D status have both been associated with increased risk of elevated systolic blood pressure (SBP) in previous research. However, these associations have never been investigated in the same study population, leaving the question of a possible interaction uninvestigated. One potential mechanism for an interaction is that SSB intake may increase serum uric acid (UA) and UA may interfere with utilization of vitamin D. This study examined these relationships in a sample of men and women (n=2,875) aged 20-74 using data collected in the 2003-2006 NHANES survey. No statistically significant association was found between SSB intake and risk of elevated SBP (defined as SBP>120mmHg) in whole group analysis. In subgroup analysis by gender, women (n=1,550) showed a 68% (OR: 1.68, 95% CI: 1.12-2.50, p-value 0.011) increased risk of elevated SBP in the highest SSB intake quartile (mean intake of 3.27 servings/day) compared to the lowest (mean intake of 0.03 servings/day) after adjustment for age, race, BMI, alcohol use, physical activity, and smoking, but no association was found in men (n=1,325). A statistically significant association was found between 25(OH)D and SBP, with a 30% decrease in risk of elevated SBP (OR: 0.70, 95% CI: 0.55-0.90, p-value 0.005) for those in the highest serum 25(OH)D group (>75nmol/L) compared to the lowest (<50nmol/L) in the fully adjusted model. However, no association was found between SSB intake and serum UA. Assessing potential effect modification between SSB and vitamin D in their impact on blood pressure using a multiplicative term and stratified analysis did not provided evidence of an interaction effect.

description: The vertebral biopsy is the method of choice to confirm the diagnosis of localized infectious and tumoral lesions of the spine. It can be performed percutaneously or in the open. The percutaneous route has largely supplanted surgical biopsy with a minimally invasive spinal approach and diagnostic efficiency. The transpedicular biopsy is the most classic. We report our experience through a series of six cases of transpedicular vertebral biopsy collected during a two-year period in the neurosurgery department at Mohamed VI University Hospital in Oujda Morocco.
Modelling Bird Migration with Motus Data and Bayesian State-Space Models
Creators: name: Baldwin, Justin
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Bird migration is a poorly-known yet important phenomenon, as understanding movement patterns of birds can inform conservation strategies and public health policy for animal-borne diseases. Recent advances in wildlife tracking technology, in particular the Motus system, have allowed researchers to track even small flying birds and insects with radio transmitters that weigh fractions of a gram. This system relies on a community-based distributed sensor network that detects tagged animals as they move through the detection nodes on journeys that range from small local movements to intercontinental migrations. The quantity of data generated by the Motus system is unprecedented, is on its way to surpass the size of all other centralized databases of animal detection and requires novel statistical methods. Building from the bsam package in R, I propose two new biologically informed Bayesian state-space models for animal movement in JAGS that include informed assumptions about songbird behavior. I evaluate the models using a simulation study in realistic conditions of data missingness. One of these models is generalized to a hierarchical version that fits population-level movement through joint estimation of movement parameters over multiple animal tracks. To apply the models, I then employ a localization routine on a Motus data set from migrating songbirds (Red-eyed Vireos - Vireo olivaceus) from the Eastern coast of North America. This allows me to apply the new hierarchical model and its predecessor to estimate unobserved locations and behaviors. Migratory flights were observed to occur mostly in the evenings along the coast and directed migratory flights were detected over water over e.g. the Bay of Fundy, the Long Island Sound and the New York Bight. Area-restricted searches were confined to coastal areas, in particular the Gulf of Maine, Long Island and Cape May.

description: ABSTRACT

This research investigates the role of Human Resources (HR) in Somali organizations, particularly in the context of post-civil war economic development. The study aimed to enhance HR practices to support sustainable growth, improve organizational effectiveness, and foster economic development in Somalia. Key objectives included examining resource constraints faced by HR professionals, exploring the influence of traditional Somali work culture on HR practices, and evaluating the legal framework for HR in Somalia. The research employed a mixed-methods approach, collecting data through surveys and interviews with HR professionals, employees, and organizational leaders. A total of 117 observations were collected and analyzed using Stata. Findings revealed significant resource constraints, including limited financial resources, inadequate technological infrastructure, and a shortage of qualified HR professionals, which negatively impacted HR functions and strategies. The influence of traditional Somali culture, characterized by collectivism, hierarchy, and informal communication, posed both opportunities and challenges for HR practices. Additionally, the study highlighted weaknesses in the legal framework, with inconsistent enforcement and gaps in labor protections. These findings underscored the need for comprehensive reforms, enhanced investment in HR, and the adoption of culturally sensitive and legally compliant HR practices. The study's conclusions emphasized the importance of addressing resource constraints, navigating cultural dynamics, and strengthening the legal framework to enhance HR capabilities within Somali organizations. Recommendations included prioritizing HR investment, developing local HR talent, fostering cultural sensitivity, advocating for legal reforms, and promoting digital literacy and technological infrastructure. Suggestions for further research were proposed, focusing on comprehensive HR metrics, employee voice and participation, gender dynamics, organizational learning and innovation, and the integration of sustainability and corporate social responsibility principles. This research contributes to the understanding of HR practices in post-conflict settings, offering practical insights and strategic interventions to support organizational development and economic growth in Somalia.

description: We propose a systematic and constructive way to determine the exchange-correlation potentials of density-functional theories including vector potentials. The approach does not rely on energy or action functionals. Instead it is based on equations of motion of current quantities (force balance equations) and is feasible both in the ground-state and the time-dependent setting. This avoids, besides differentiability and causality issues, the optimized-effective-potential procedure of orbital-dependent functionals. We provide straightforward exchange-type approximations for different density functional theories that for a homogeneous system and no external vector potential reduce to the exchange-only local-density and Slater X$α$ approximations.

description: The Household Dietary Diversity Score (HDDS) was developed to measure household food access, one of the levels of food security. Previous research has shown dietary diversity is related to food security. However, the specific way in which the HDDS measures food security has never been validated. Based on the results of a Rasch model on datasets from Colombia and Ecuador we conclude this indicator in its current form is not internally valid, has limited external validity only in our Colombian data, and is not comparable across cultural settings. More research is warranted into the food groups that make up the indicator as well as the recall period on which it is based.

description: This paper analyses empirically the impact of food aid on production, sales and purchases. We estimate the discrete choice and the level choice using the Ethiopian rural household survey. The panel dimension allows us to deal with food aid selection. Running a panel Tobit with sample selection and endogeneity we find that food aid reduces the probability of being a producer. It increases the one of being a seller and decreases the one of being a buyer only after 2004 that corresponds to changes in the criteria of food aid allocation. Food aid does not affect the level choice.

description: There has been a great deal of recent interest in India’s food security, as evidenced by intensive discussions on India’s National Food Security Act (NFSA) and proposed changes to its food subsidy programs. The NFSA is both ambitious and full of potential problems, as it aims at guaranteeing the provision of subsidized food grains for around 70 percent of its vast population and is built upon India’s existing food security policy, which has caused enormous fiscal burden, particularly during the recent world food price crisis. This study uses a computable general equilibrium model to evaluate the fiscal and welfare costs of the market stabilization and insulating food policy of India during the 2007-08 global food crisis. We demonstrate that domestic food grain price stabilization through simultaneously subsidizing consumers and producers and restricting exports entailed huge fiscal costs and equally large welfare costs to India, an outcome that is almost always the worst as compared to the alternative policy mixes examined in this study. While the most market-oriented domestic and trade policy alternatives that would generate better welfare effects and the least fiscal costs may not be feasible due to political economy considerations, we argue that there exist some “middle-ground” policy mixes featuring partial relaxations of domestic subsidizations on either food grains or fertilizers and/or less restrictive border policies. These policy mixes are superior in terms of their welfare effects and fiscal costs and might also be politically possible.

description: Rotating all islands in square artificial spin ice (ASI) uniformly about their centres gives rise to the recently reported pinwheel ASI. At angles around 45$^\mathrm{o}$, the antiferromagnetic ordering changes to ferromagnetic and the magnetic configurations of the system exhibit near-degeneracy, making it particularly sensitive to small perturbations. We investigate through micromagnetic modelling the influence of dipolar fields produced by physically extended islands in field-driven magnetisation processes in pinwheel arrays, and compare the results to hysteresis experiments performed in-situ using Lorentz transmission electron microscopy. We find that magnetisation end-states induce a Heisenberg pseudo-exchange interaction that governs both the inter-island coupling and the resultant array reversal process. Symmetry reduction gives rise to anisotropies and array-corner mediated avalanche reversals through a cascade of nearest-neighbour (NN) islands. The symmetries of the anisotropy axes are related to those of the geometrical array but are misaligned to the array axes as a result of the correlated interactions between neighbouring islands. The NN dipolar coupling is reduced by decreasing the island size and, using this property, we track the transition from the strongly coupled regime towards the pure point dipole one and observe modification of the ferromagnetic array reversal process. Our results shed light on important aspects of the interactions in pinwheel ASI, and demonstrate a mechanism by which their properties may be tuned for use in a range of fundamental research and spintronic applications.

description: This study deals with horizontal wheat price transmission from the international markets to the domestic Swiss market. The analysis takes into account trade policies implemented at the borders that might shelter the domestic market from international markets fluctuations, as well as the presence of explosive behavior in some of the price series. Furthermore, the Swiss case is peculiar due to the presence of different border policies for wheat according to its domestic use, food or feed. The paper investigates price transmission in this segregated domestic market under the respective different border policies but still acknowledging possible linkages among the two market segments. Vector Error Correction models with structural breaks are estimated, allowing to account for the influence of periods of market exuberance in the international markets as well as of the consequent policy regime changes.
Investigating Natural and Induced Biofilm Dispersion in Listeria monocytogenes
Creators: name: Boulden, Brett
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Dispersion is a natural part of a biofilm life cycle in many bacterial species. Dispersion occurs when bacteria revert from a stationary, sessile state to a free-swimming, planktonic state and are freed from a biofilm. Bacterial biofilms consist of proteins, polysaccharides, and extracellular DNA that together make up the extracellular polymeric substances. Surrounded by this mucus-like substance, sessile cells can be extremely difficult to eradicate as compared to the planktonic form of Listeria monocytogenes. Biofilms are robust due to increased surface adherence, inhibition of diffusion of harmful compounds, and increased genetic diversity that exists within a biofilm. As a result, traditional biofilm removal methods are often inadequate; and a novel method for the eradication of Listeria monocytogenes biofilms is needed. Here it is shown that two known biofilm dispersal agents, nitric oxide and cis-2-Decenoic acid, do not induce dispersion in Listeria monocytogenes strain LM23. Nitric oxide and cis-2-Decenoic acid do not influence planktonic cell numbers or biofilm biomass. Ten carbohydrates were screened for their influence on biofilm biomass for use in investigation into natural biofilm dispersion in Listeria monocytogenes strain LM23. Carbohydrate source can significantly increase or decrease biofilm biomass as compared to glucose. Natural biofilm dispersion in Listeria monocytogenes remains inconclusive, yet warrants further investigation. Changes in planktonic cells numbers, sessile cell numbers, and biofilm biomass were tracked under static growth conditions, and suggested a possible dispersion event. However, treatment of biofilms with spent media and observation using scanning electron microscopy did not clarify the results obtained. This research deems the nitric oxide donors, molsidomine (N- (ethoxycarbonyl)-3-(4-morpholinyl)-sydnone imine) and MAHMA NONOate (6-(2-Hydroxy-1-methyl-2-nitrosohydrazino)-N-methyl-1-hexanamine), as well as cis-2-Decenoic acid as ineffective in inducing biofilm dispersion. It also brings about new research questions into natural biofilm dispersion in Listeria monocytogenes.

description: We apply renormalisation-group methods to two-body scattering by a combination of known long-range and unknown short-range potentials. We impose a cut-off in the basis of distorted waves of the long-range potential and identify possible fixed points of the short-range potential as this cut-off is lowered to zero. The expansions around these fixed points define the power countings for the corresponding effective field theories. Expansions around nontrivial fixed points are shown to correspond to distorted-wave versions of the effective-range expansion. These methods are applied to scattering in the presence of Coulomb, Yukawa and repulsive inverse-square potentials.

Validity of ADHD Symptoms in Toddlers
Creators: name: Brown, Hallie
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Attention deficit/hyperactivity disorder (ADHD) is one of the most common child neurodevelopmental disorders. The disorder is typically diagnosed in elementary school, but there is growing evidence for the validity of ADHD in preschoolers, and symptoms likely emerge even earlier than preschool years. Research suggests that ADHD symptoms can be evident in toddlers beyond developmentally appropriate behavior, and symptoms in toddlers are predictive of later impairment. However, few studies have examined the validity of Diagnostic and Statistical Manual of Mental Disorders (DSM) ADHD symptoms in this younger population. The present study examined the 18 DSM ADHD symptoms in a community sample of 2-year-old children by recruiting parents (N = 321) online through Amazon’s Mechanical Turk. Results showed that ADHD symptoms were fairly common in 2-year-old children; a substantial minority (22%) of children met symptom criteria for ADHD. ADHD showed similar construct validity and symptom utility to older children, with the exception of verbal hyperactive-impulsive symptoms. Similar to school-age children, a two-factor model of ADHD, was the best fit. ADHD symptoms showed convergent and divergent validity with a temperament questionnaire; symptoms were related to similar traits such as motor activation and inhibitory control, and not related to traits such as cuddliness or fear. Finally, item response theory analyses showed that items besides verbal symptoms discriminated well between toddlers high and low on ADHD. Results suggest that ADHD symptoms, with the exception of verbal symptoms, demonstrate good validity in 2-year-old children, and provide support for conducting prospective studies to determine whether 2-year-old children showing high levels of ADHD symptoms are at high risk for the development of ADHD.
The Effects of Central transfers on Local Own-Revenue: The Case of Morocco
Creators: name: Meriem MIRI
Publisher: name: figshare

Subjects: Economics

description: The purpose of this work is to evaluate the effects of transferred central revenues on local own revenues. The nature of these effects remains ambiguous according to theoretical and empirical literature review, especially for developing countries. Indeed, these effects are analyzed in the context of a behavior’s imbalance that can be caused by decentralization between local expenditures and their coverage by local own revenues. We are interested in Morocco for the period 2002-2014, taking into consideration all the Moroccan territorial communities grouped by the 16 regions. The effects are analyzed for total own revenue and then for each type of own-revenues and taking into account the endogeneity effect of transfers as a key issue. It is concluded that an increase in transferred central revenues does not necessarily encourage local own revenues in Morocco. This unfavorable effect is more important for the poorest regions than for non-poorest ones.
Partial Craniofacial Cartilage Rescue in ace/fgf8 Mutants from Compensatory Signaling From the Ventricle of Danio Rerio
Creators: name: Calenda, Douglas A
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Examples of asymmetric organs are found throughout the animal kingdom. Whether it is superficial like the fiddler crab’s claw or within an organism like our visceral organs, asymmetries have repeatedly evolved in nature. However, the genetic and developmental origins for asymmetric organ development remain unclear, especially for superficially paired structures. Within zebrafish, a striking example of asymmetry occurs within the ace/fgf8 mutant. The pharyngeal cartilages of these mutants develop asymmetrically 35% of the time, with more cartilages developing on the left or right side of the head, but the origins of this asymmetry are unknown. A significant proportion of mutants also exhibit situs inversus, whereby the visceral organs develop on the opposite side of the body. Here we seek to understand the temporal window most sensitive to giving rise to this asymmetry, and to understand if there is a correlation between the developing heart field and pharyngeal cartilage with respect to the direction of the asymmetry.
Wild type (WT) zebrafish were exposed to SU5402 during different periods of development, and heart position as well as cartilage development was observed within the developing larvae. The direction of asymmetry (i.e., left or right biased) was also recorded in ace/fgf8 mutant heart position and cartilage number to observe if there was a correlation between the two developing fields. SU5402 experiments revealed that the time window most sensitive to the development of cartilage asymmetries was during heart looping and pharyngeal arch segmentation. Furthermore, ace/fgf8 mutants exhibited a robust correlation between ventricle position and the side of cartilage asymmetry, with more cartilages forming on the side where the ventricle is located. Given the close proximity of the heart and pharyngeal cartilage fields we suggest that the heart field is influencing the developing cartilage, with signaling permeating from the developing heart to the pharyngeal mesoderm to provide a buffer on the side of the developing ventricle.

The yield of prompt $J/ψ$ mesons in the $Υ(4S)$ sample is compatible with that of continuum production; we set an upper limit ${\cal B}(Υ(4S) \to J/ψX) < 1.9 \times 10^{-4}$ at the 95% confidence level, and find $σ(e^{+}e^{-} \to J/ψX)=1.47\pm 0.10 \pm 0.13$ pb. The cross-sections for prompt $ψ(2S)$ and direct $J/ψ$ are measured. The $J/ψ$ momentum spectrum, production angle distribution and polarization are studied.

 HOLOTYPE female: “ Texas; Uvalde County. Rambie’s Cave, 8 miles N of Uvalde, April 6, 1963 J. Reddell, D. McKenzie ”. Examined (AMNH).
 Description. Female holotype
 Epigynum length: 0.161 (half size). Epigynal ventral plate with short transverse slit, bearing medial, shallow, inverted U-shaped indentation; atrium squared, two-thirds intruded by rounded dorsal plate, atrial Cicurina uvalde Gertsch 1992. 114–115 Cicurina venefica Gertsch 1992. 116–117 Cicurina venii Gertsch 1992. 118–119 Cicurina vespera Gertsch 1992. 120–121 Cicurina vibora Gertsch 1992. 122–123 Cicurina wartoni Gertsch 1992. 124–125 Cicurina watersi Gertsch 1992. 126–127 Cicurina wiltoni Gertsch 1992. Scale bar = 0.1 mm.
 Distribution. Only reported from the type locality: Rambie’s Cave (Uvalde County, Texas, Fig. 135).
 Remarks. Male unknown. The holotype vial contained a broken epigynum and one mature female not dissected. We are presuming that the broken epigynum is the remnant of the holotype represented by Gertsch because he drew ventral and dorsal views (Figs 101–102) that could only be seen with a dissected specimen. Gertsch (1992) did not mentioned any other mature specimen other than the holotype for the species, only 18 immatures that were not found in the vial. The description presented here for Cicurina uvalde is incomplete because the holotype is damaged.

description: This paper investigates price transmission in beef and veal markets in Switzerland. We extend earlier research by analyzing both prices in one system and considering two different marketing channels for meat. VAR and VEC models are estimated using monthly up- and downstream prices collected at the processors’ level for 2004-2013. Tests on Granger causality for these markets suggest that a) multiple product investigation should be preferred over beef (or veal) only analysis and b) the results for the same product can differ across marketing channels. In both channels, veal (and not beef) prices adjust significantly if deviations from the long-run price equilibrium occur. Nonetheless, no empirical evidence can be found that downstream industries exercise market power over producers. In all marketing channels, no significant asymmetry in price transmission is found.

description: This is the first paper to analyze the impact of biofuels on the price transmission along the food chain. Specifically, we analyze the U.S. corn sector and its vertical links to food and ethanol markets. The key result of this paper is that the presence of biofuels affects the price transmission elasticity only when the blender's tax credit is binding and the shock originates in the food market. Our another important result is that the response of corn and food prices to exogenous shocks in the corn or food markets is always lower in the presence of biofuels when the tax credit is binding. However, the results are mixed for the binding mandate. The sensitivity analyses indicate that our results are robust to different assumptions about the model parameters.

description: We propose a new set of supersymmetric benchmark scenarios, taking into account the constraints from LEP, b to s gamma, g_mu - 2 and cosmology. We work in the context of the constrained MSSM (CMSSM) with universal soft supersymetry-breaking masses and assume that R parity is conserved. We propose benchmark points that exemplify the different generic possibilities, including focus-point models, points where coannihilation effects on the relic density are important, and points with rapid relic annihilation via direct-channel Higgs poles. We discuss the principal decays and signatures of the different classes of benchmark scenarios, and make initial estimates of the physics reaches of different accelerators, including the Tevatron collider, the LHC, and e+ e- colliders in the sub- and multi-TeV ranges. We stress the complementarity of hadron and lepton colliders, with the latter favoured for non-strongly-interacting particles and precision measurements. We mention features that could usefully be included in future versions of supersymmetric event generators.

description: We discuss interacting quantum field theory in de Sitter space and argue that the Mottola-Allen vacuum ambiguity is an artifact of free field theory. The nature of the nonthermality of the MA-vacua is also clarified. We propose analyticity of correlation functions as a fundamental requirement of quantum field theory in curved spacetimes. In de Sitter space, this principle determines the vacuum unambiguously and facilitates the systematic development of perturbation theory.

description: Τhe Belt and Road is expanding and the need to provide security to the Chinese infrastructure projects (railways and sea roads) and to protect the interests of Chinese companies is growing. China’s growing engagement with Africa is increasing the need for a more pro-active Chinese role in African security and for further support to Africa for achieving a balance between security and development. China has increased involvement in the UN peacekeeping in Africa, peace and security cooperation has become of the most important pillars of the comprehensive strategic partnership between China and Africa. The Belt and Road Initiative provides opportunities for strengthening China-Africa dialogue on peace and security which is an important driver for China-Africa relations.
Improving the Robustness of Capsule Networks to Image Affine Transformations

description: Convolutional neural networks (CNNs) achieve translational invariance by using pooling operations. However, the operations do not preserve the spatial relationships in the learned representations. Hence, CNNs cannot extrapolate to various geometric transformations of inputs. Recently, Capsule Networks (CapsNets) have been proposed to tackle this problem. In CapsNets, each entity is represented by a vector and routed to high-level entity representations by a dynamic routing algorithm. CapsNets have been shown to be more robust than CNNs to affine transformations of inputs. However, there is still a huge gap between their performance on transformed inputs compared to untransformed versions. In this work, we first revisit the routing procedure by (un)rolling its forward and backward passes. Our investigation reveals that the routing procedure contributes neither to the generalization ability nor to the affine robustness of the CapsNets. Furthermore, we explore the limitations of capsule transformations and propose affine CapsNets (Aff-CapsNets), which are more robust to affine transformations. On our benchmark task, where models are trained on the MNIST dataset and tested on the AffNIST dataset, our Aff-CapsNets improve the benchmark performance by a large margin (from 79% to 93.21%), without using any routing mechanism.
