description: In the current study, we evaluated the modulatory effects of size and surface coating/charge of AgNPs on their toxicity to a unicellular yeast Saccharomyces cerevisiae BY4741 – a fungal model. For that, the toxicity of a set of 10 and 80 nm citrate-coated (negatively charged) and branched polyethylenimine (bPEI) coated (positively charged) AgNPs was evaluated in parallel with AgNO3 as ionic control. Yeast cells were exposed to different concentrations of studied compounds in deionized water for 24 h at 30 °C and evaluated for the viability by the post-exposure colony-forming ability. Particle-cell interactions were assessed by SEM, TEM and confocal laser scanning microscopy (CLSM) in the reflection mode. AgNPs toxicity to yeast was size and charge-dependent: 24-h IC50 values ranged from 0.04 (10nAg-bPEI) up to 8.3 mg Ag/L (80nAg-Cit). 10 nm AgNPs were 5–27 times more toxic than 80 nm AgNPs and bPEI-AgNPs 8–44 times more toxic than citrate-AgNPs. SEM and TEM visualization showed that bPEI-AgNPs but not citrate-AgNPs adsorbed onto the yeast cell’s surface. However, according to CLSM all the studied AgNPs, whatever the size and coating, ended up within the yeast cell. Toxicity of citrate-AgNPs was largely explained by the dissolved Ag ions but the bPEI-AgNPs showed mainly particle-driven effects leading to the cellular internalization and/or to more pronounced dissolution of AgNPs in the close vicinity of the cell wall. Therefore, the size, and especially the coating/charge of AgNPs can be efficiently used for the design of new more efficient antifungals.

description: This paper examines the immediate effects of group methods in facilitating remote team collaboration. We recruited seven teams with prior experience working together. All teams completed two current, complex, and open-ended design challenges using remote tools. We examined design activities before and after teams were given a design method intervention. The interventions were a Brainstorming Method to promote divergent thinking and the Five-Whys method to promote analytical thinking. Using OpenFace, we observed changes in emotion by examining facial expressions. We found that the brainstorming intervention did not have a change in ideation performance and the problem analysis intervention had a decrease in ideation performance. Teams used digital media to facilitate communication but were constrained by the media's tools. Our results can inform teams in organizations interested in promoting divergent thinking to not expect immediate improvements in ideation performance following the introduction of a design method. Future research is required to identify relevant abilities and social skills needed to facilitate remote ideation through design methods.

description: This article aims to present the results of the analysis of the physical environment in the municipality of Caculé, located in the center-south of the State of Bahia, with an area of 686km². The central objective of the research was to show the physiographic, phytophysiognomic and climatic conditions in the area. The methodology used was based on theoretical analysis, observations and application of methods in the field with the aid of GPS, preparation of maps and chemical and physical analysis of soils, climatological data and use of geoprocessing. The results obtained through the maps showed that the municipality is part of geomorphological units belonging to crystalline plateaus, more precisely in the Planalto das Bordas do Espinhaço and geomorphological features called pediplanate depressions, specifically in the Patamares do Médio Rio de Contas. Its predominant topography varies from gently undulating to undulating with altitudes ranging on average from 1000 to 550m. It was found from cartographic investigation and field observation that the predominant rocks in the region are: tunalite gneisses and granodiorites, diapiric granite bodies and quartzites. From soil fertility analyzes it was generally found that they are considered to have good to regular fertility. They are classified as red-yellow latosol, dark red latosol and eutrophic red-yellow podzolic. To verify the water conditions in the soil, as well as classify the climate typology for the municipality, the Thornthwaite water accounting method was used. The rainfall graphs show that the municipality of Caculé presents a large annual and monthly variation in precipitation. The hydrographic network shows a dendritic pattern and some dams on the map. With regard to vegetation, in the field and in the existing literature, the predominance of open arboreal caatinga without palm trees, deciduous seasonal forest and dense arboreal caatinga with palm trees that have been significantly altered by human action was observed. The environmental diagnosis made it possible to verify that it is a municipality suitable for agricultural activity due to its good soil fertility and favorable topography.

We establish the phase diagram of the dissipative problem and investigate the changes in the Curie temperature, magnetization, and magnetic correlation length due to dissipation and both thermal and quantum fluctuations. We show that the interplay between the topological term (Berry's phase) and dissipation leads to non-trivial effects for the finite temperature critical behavior.

description: The growth of New York City between the 1880s and the 1930s produced a remarkable building boom that reshaped the landscape of the city. In these years the city acquired its modern skyline, many of its civic monuments, and much of the housing its residents live in today. The development of new architectural styles, building materials, and construction methods in this period also introduced profound changes in the way buildings were produced. The soaring demand for new construction stimulated the rise of new kinds of architecture, building, and contracting firms, revitalized the building trades, and transformed the city’s building industry. This dissertation explores the building of the city from the perspective of those who were engaged in its production to shed new light on the history of the city. Focusing on the creation of some of the city’s most important buildings, it traces the efforts of architects, builders, and workers to the shape the building process as it became increasingly industrialized. While architects, general contracting companies, and subcontractors exercised growing authority within the building industry, construction ultimately depended upon skilled building craftsmen. Thanks to their collective action, workers successfully fought to maintain the integrity of their trades and exert control over their work. Over time, architects, building employers, and workers established cooperative agreements which helped to stabilize a volatile industry. This study contains five chapters that examine the work of leading New York architects as a window onto the transformation of building practice over half a century. Using the records of architecture firms, building trade publications, and municipal records, it documents the changing character of the building industry in a period of rapid urban growth, technological change, and industrial conflict. By looking at the making of buildings as a form of production, it reframes architectural history around the conflicts that shaped the building process between the late nineteenth century and the Great Depression.

description: We investigate the physical mechanisms of high-energy gamma-ray emission from the TeV-emitting misaligned active galactic nucleus IC 310. Eight years of data from the Fermi Large Area Telescope (Fermi-LAT) between 100 MeV and 500 GeV are reduced and analysed to study the temporal and spectral characteristics of IC 310. Point spread function-partitioned instrument response functions are used to improve the resolvability of IC 310 from nearby NGC 1275. Systematic effects due to this choice of instrument response functions and the proximity of NGC 1275 are investigated. We find strong spectral variability and detect the hard flaring state of IC 310 along with a previously undiscovered soft state in quiescent periods, and the first detection with Fermi-LAT below 1 GeV. This represents a shift in peak Compton energy of more than five orders of magnitude. Possible interpretations are discussed, but we lack the instantaneous sensitivity with Fermi to probe the underlying physics.

description: The Asia-Pacific region is one of the most vulnerable regions in the world to flooding. This vulnerability will only increase with rapid urbanization placing more people and infrastructure in harms way. At the same time, rapid urbanization is leading to environmental degradation reducing economic growth. The EU’s world-leading experiences in city planning, infrastructure services and management creates the potential for Europe to export green infrastructure solutions to ensure rapidly expanding Asian cities have sustainable infrastructure. This also has the potential to create economic growth and job creation in Europe.

description: A model checking computation checks whether a given logical sentence is true in a given finite structure. Provenance analysis abstracts from such a computation mathematical information on how the result depends on the atomic data that describe the structure. In database theory, provenance analysis by interpretations in commutative semirings has been rather succesful for positive query languages (such a unions of conjunctive queries, positive relational algebra, or datalog). However, it did not really offer an adequate treatment of negation or missing information. Here we propose a new approach for the provenance analysis of logics with negation, such as first-order logic and fixed-point logics. It is closely related to a provenance analysis of the associated model-checking games, and based on new semirings of dual-indeterminate polynomials or dual-indeterminate formal power series. These are obtained by taking quotients of traditional provenance semirings by congruences that are generated by products of positive and negative provenance tokens. Beyond the use for model-checking problems in logics, provenance analysis of games is of independent interest. Provenance values in games provide detailed information about the number and properties of the strategies of the players, far beyond the question whether or not a player has a winning strategy from a given position.

description: As theoretical neuroscience has grown as a field, machine learning techniques have played an increasingly important role in the development and evaluation of theories of neural computation. Today, machine learning is used in a variety of neuroscientific contexts from statistical inference to neural network training to normative modeling. This dissertation introduces machine learning techniques for use across the various domains of theoretical neuroscience, and the application of these techniques to build theories of neural circuits. First, we introduce a variety of optimization techniques for normative modeling of neural activity, which were used to evaluate theories of primary motor cortex (M1) and supplementary motor area (SMA). Specifically, neural responses during a cycling task performed by monkeys displayed distinctive dynamical geometries, which motivated hypotheses of how these geometries conferred computational properties necessary for the robust production of cyclic movements. By using normative optimization techniques to predict neural responses encoding muscle activity while ascribing to an “untangled” geometry, we found that minimal tangling was an accurate model of M1. Analyses with trajectory constrained RNNs showed that such an organization of M1 neural activity confers noise robustness, and that minimally “divergent” trajectories in SMA enable the tracking of contextual factors. In the remainder of the dissertation, we focus on the introduction and application of deep generative modeling techniques for theoretical neuroscience. Specifically, both techniques employ recent advancements in approaches to deep generative modeling -- normalizing flows -- to capture complex parametric structure in neural models. The first technique, which is designed for statistical generative models, enables look-up inference in intractable exponential family models. The efficiency of this technique is demonstrated by inferring neural firing rates in a log-gaussian poisson model of spiking responses to drift gratings in primary visual cortex. The second technique is designed for statistical inference in mechanistic models, where the inferred parameter distribution is constrained to produce emergent properties of computation. Once fit, the deep generative model confers analytic tools for quantifying the parametric structure giving rise to emergent properties. This technique was used for novel scientific insight into the nature of neuron-type variability in primary visual cortex and of distinct connectivity regimes of rapid task switching in superior colliculus.

description: We consider the pure supersymmetric Yang--Mills theories placed on a small 3-dimensional spatial torus with higher orthogonal and exceptional gauge groups. The problem of constructing the quantum vacuum states is reduced to a pure mathematical problem of classifying the flat connections on 3-torus. The latter problem is equivalent to the problem of classification of commuting triples of elements in a connected simply connected compact Lie group which is solved in this paper. In particular, we show that for higher orthogonal SO(N), N > 6, and for all exceptional groups the moduli space of flat connections involves several distinct connected components. The total number of vacuumstates is given in all cases by the dual Coxeter number of the group which agrees with the result obtained earlier with the instanton technique.

description: The information contained in a time series is more than what the values themselves are. In this paper, the Time-variant Local Autocorrelated Polynomial model with Kalman filter is proposed to model the underlying dynamics of a time series (or signal) and mine the deep pattern of it, except estimating the instantaneous mean function (also known as trend function), including: (1) identifying and predicting the peak and valley values of a time series; (2) reporting and forecasting the current changing pattern (increasing or decreasing pattern of the trend, and how fast it changes). We will show that it is this deep pattern that allows us to make higher-accuracy estimation and forecasting for a time series, to easily detect the anomalies (faults) of a sensor, and to track a highly-maneuvering target.
title: From Negative to Positive Legislator? Response to Unconstitutional Legislative Omission As a Case Study in the Changing Roles of Constitutional Courts

description: An important but challenging development appears to be occurring in the character of some constitutional courts—a shift from their traditional role as a negative legislator to a significant role as a positive legislator. Under this shift, a constitutional court is no longer confined to declaring the unconstitutionality of statutes if they are contrary to the constitution and simply annulling them, but rather takes on a positive power to create statute law. The case study examined here is the power to fill the gaps caused by unconstitutional legislative omissions (ULOs). Such a power authorises a constitutional court to declare what a missing law should contain, and to draft and promulgate that law, thus assuming the role of positive legislators by enacting temporary or provisional rules on specific matters. This development in the power of constitutional courts provokes vital questions. Why has such a role developed? What are its most important manifestations? What are the benefits and risks of such powers? Do the benefits outweigh the risks, and how might benefits be maximised and risks minimised? In response to these questions, this study provides a deeper understanding of the apparent shift in constitutional courts’ power from negative to positive legislator, and its implications for countries struggling with establishment and maintenance of democracy. The study applies lessons from international experience of powers to rectify ULOs in 17 countries, to examine whether such powers help address these challenges in more legal systems, and if so, how. It finds that some forms of such a power do have a positive contribution to make in response to serious constitutional challenges, but two things are required: a general recognition that the traditional understanding of a constitutional court as a purely negative legislator is no longer sufficient to explain and evaluate its role, once entrusted with such a power; and a new approach to the design of such a power, such as developed and applied in this thesis, which enables this ‘positive legislator’ role to be granted in a manner that still protects core values of liberal democracy.

description: Climate change is a growing challenge facing the entire world. Today, most actions are aimed at mitigation. However, some climate change impacts will be unavoidable. This explains a growing interest in adaptation to climate change. On a political level, adaptation is a challenging concept. At this level, there is a growing literature on “climate policy integration” theory (stemming from the environmental policy integration paradigm). It proposes to take climate change into account in each and every sectoral policy. This contribution addresses the way to integrate climate change adaptation into policies. We will focus on regional and external adaptation strategies, from a theoretical and practical perspective. First, we will present the concept of adaptation, as a political challenge. The “climate policy integration” theory will be defined and its practical application, which has links with both vertical and horizontal integration of adaptation, will be explained. A second part of our paper will address the practical implementation of climate change adaptation at two policy levels. We will first analyse regional adaptation strategies and plans of several European countries, with regards to integration of adaptation in different sectors. These policy instruments will be analysed, as well as the perception of adaptation by various concerned actors at the regional level. Secondly, the focus will be on how adaptation to climate change can be integrated into external policies. This will be studied through development aid. Two different approaches will be described. Institutions such as the E.U. or the World Bank often highlight the need to take climate change into account while working on any development projects. This is the so-called mainstreaming approach. On the contrary, a sectoral approach of adaptation, such as proposed by NAPAs , will be aimed at reducing the vulnerability of a specific sector. Both approaches will be analysed, through scientific and official literature.

We then apply our construction to find the M-5-brane worldvolume solitons in an AdS background that saturate this bound. We show that these worldvolume solitons are supersymmetric and that they satisfy differential equations which generalize those of standard calibrations.

description: Background: A better understanding of determinants for drug survival of antipsoriatic agents may guide dermatologists in the right therapeutic choice. Objectives: To describe 2-year drug survival of conventional and biologic antipsoriatic treatments. Methods: SAHARA was a prospective study in patients with moderate-to-severe psoriasis who initiated a conventional or biologic drug. Kaplan-Meier analysis estimated the drug survival and Cox regression the predictors of treatment persistence at two years. Results: A total of 552 patients were included (conventional group n = 181, biologic group n = 371). After a median treatment duration of 21.4 months, more than 50% of patients remained on methotrexate, etanercept, and ustekinumab whereas the median exposition time to cyclosporine, acitretin, and adalimumab was 11.8, 10.6, and 25.5 months, respectively. There were 178 discontinuations for all causes, mainly in patients who initiated cyclosporine (58.3%), acitretin (52.8%), and adalimumab (46%), and less frequently with ustekinumab (14%). The main reason for discontinuing biologics was lack of efficacy (70%), especially for etanercept (76%). Conclusion: Biologics have a superior drug survival rate than conventional therapies. Ustekinumab is the biologic with the longest drug survival, only affected by the gradual loss of efficacy assumed for biological therapies.

description: Flooding is an essential and critical service in computer networks that is used by many routing protocols to send packets from a source to all nodes in the network. As the packets are forwarded once by each receiving node, many copies of the same packet traverse the network which leads to high redundancy and unnecessary usage of the sparse capacity of the transmission medium. Gossip routing is a well-known approach to improve the flooding in wireless multi-hop networks. Each node has a forwarding probability p that is either statically per-configured or determined by information that is available at runtime, e.g, the node degree. When a packet is received, the node selects a random number r. If the number r is below p, the packet is forwarded and otherwise, in the most simple gossip routing protocol, dropped. With this approach the redundancy can be reduced while at the same time the reachability is preserved if the value of the parameter p (and others) is chosen with consideration of the network topology. This technical report gives an overview of the relevant publications in the research domain of gossip routing and gives an insight in the improvements that can be achieved. We discuss the simulation setups and results of gossip routing protocols as well as further improved flooding schemes. The three most important metrics in this application domain are elaborated: reachability, redundancy, and management overhead. The published studies used simulation environments for their research and thus the assumptions, models, and parameters of the simulations are discussed and the feasibility of an application for real world wireless networks are highlighted. Wireless mesh networks based on IEEE 802.11 are the focus of this survey but publications about other network types and technologies are also included. As percolation theory, epidemiological models, and delay tolerant networks are often referred as foundation, inspiration, or application of gossip routing in wireless networks, a brief introduction to each research domain is included and the applicability of the particular models for the gossip routing is discussed.

description: In the study of quantum limits to parameter estimation, the high dimensionality of the density operator and that of the unknown parameters have long been two of the most difficult challenges. Here we propose a theory of quantum semiparametric estimation that can circumvent both challenges and produce simple analytic bounds for a class of problems in which the dimensions are arbitrarily high, few prior assumptions about the density operator are made, but only a finite number of the unknown parameters are of interest. We also relate our bounds to Holevo's version of the quantum Cramér-Rao bound, so that they can inherit the asymptotic attainability of the latter in many cases of interest. The theory is especially relevant to the estimation of a parameter that can be expressed as a function of the density operator, such as the expectation value of an observable, the fidelity to a pure state, the purity, or the von Neumann entropy. Potential applications include quantum state characterization for many-body systems, optical imaging, and interferometry, where full tomography of the quantum state is often infeasible and only a few select properties of the system are of interest.

description: The European Union’s infringement procedure is highly legalized. Nevertheless, as in other international institutions, non-compliance occurs on a regular basis and its transformation into compliance varies across EU infringement stages and over time. State of the art compliance literature focuses mainly on country-specific explanations, such as power, capacity, and legitimacy. In particular power-capacity models explain a good part of whether non-compliance occurs and how quickly it can be resolved. Yet, these approaches leave substantial parts of the empirical variation that we observe unexplained. This paper argues that policy and, in particular, rule-specific variables – although often neglected – are important for explaining non-compliance. Based on a quantitative analysis, we show that policy matters not only for the frequency with which EU law is violated, but also the persistence of non- compliance over time and over the different stages of the infringement procedure.

description: We have studied the ionic--neutral curve crossing between the two lowest ^1 Sigma^+ states of LiF in order to demonstrate the efficiency of the quantum chemistry version of the density matrix renormalization group method (QC-DMRG). We show that QC-DMRG is capable to calculate the ground and several low-lying excited state energies within the error margin set up in advance of the calculation, while with standard quantum chemical methods it is difficult to obtain a good approximation to Full CI property values at the point of the avoided crossing. We have calculated the dipole moment as a function of bond length, which in fact provides a smooth and continuous curve even close to the avoided crossing, in contrast to other standard numerical treatments.

Momentum-space geometric structure of helical evanescent waves and its implications on near-field directionality

description: In this work, a momentum-space geometrical structure in helical evanescent electromagnetic waves is revealed. It is shown that for every helical evanescent wave on a helicity-dependent half tangent line in momentum space, the orientation of each of its field, spin, and Poynting vectors is the same. This geometric structure reveals itself as a remarkable relation between the far-field and near-field components of the angular spectrum. Any general evanescent wavevector is linked to two points on the $k_ρ=k_0$ circle of propagating wavevectors via two helicity-dependent tangent lines. Knowing the field on the $k_ρ=k_0$ circle of a general dipolar source is sufficient to determine its entire evanescent angular spectrum. Applying this concept, we gain insights into near-field directionality by showing that every zero in the angular spectrum is a helicity singularity where two half-tangent lines of opposite helicity intersect. A powerful method for synthetic design of near-field directional sources is also devised, using structured helical illumination to gain full control of the near-field directionality. The results provide a fundamental insight of helical evanescent waves and have implications in areas where chiral light-matter interaction plays a central role.

Thermodynamics conditions of matter in neutron star mergers

description: Matter in neutron star collisions can reach densities up to few times the nuclear saturation threshold and temperatures up to one hundred MeV. Understanding the structure and composition of such matter requires many-body nonperturbative calculations that are currently highly uncertain.Unique constraints on the neutron star matter are provided by gravitational-wave observations aided by numerical relativity simulations. In this work, we explore the thermodynamical conditions of matter and radiation along the merger dynamics. We consider 3 microphysical equation of state models and numerical relativity simulations including an approximate neutrino transport scheme. The neutron star cores collision and their multiple centrifugal bounces heat the initially cold matter to several tens of MeV. Streams of hot matter with initial densities $\sim1-2ρ_0$ move outwards and cool due to decompression and neutrino emission. The merger can result in a neutron star remnant with densities up to $3-5ρ_0$ and temperatures $\sim 50$~MeV. The highest temperatures are confined in an approximately spherical annulus at densities $\simρ_0$. Such temperatures favour positron-neutron capture at densities $\simρ_0$, thus leading to a neutrino emission dominated by electron antineutrinos. We study the impact of trapped neutrinos on the remnant matter's pressure, electron fraction and temperature and find that it has a negligible effect. Disks around neutron star or black hole remnant are neutron rich and not isentropic, but they differ in size, entropy and lepton fraction depending on the nature of the central object. In presence of a black hole, disks are smaller and mostly transparent to neutrinos; in presence of a massive neutron star, they are more massive, geometrically and optically thick.

Business Composition Change in the 798 Art District of Beijing, and Reasons Behind It

description: This study begins with an analysis of the 798 Art District as it has existed since 2002, using historical art district maps as its primary data source. Counting and cataloging the properties on the yearly guide map has revealed that a major business composition change occurred within just this short period of time of 2007 - 2013. Since the oldest version of the historical map is that of 2007, this study’s quantitative analysis will begin at 2007 and end at 2013. As a complementary resource, this study will conduct archival research so as to fill in the gap between 2002 and 2007. The above mentioned approaches all seek to answer the research questions in a complex, comprehensive way. The emergence of 798 is a remarkable cultural phenomenon, changing Beijing’s inner-city fabric in a profound and probably a long-lasting way. By basing itself on data drawn from historical maps, and by extending the research and analysis to embrace scholarly documents, media coverage, and observations, the study will be able to probe the underlying causes of the gentrification process happening within 798.

description: Excerpts from the report: Few of the 1,400 cotton warehouses in use in 1958 were designed for the efficient use of machines for handling bales of cotton. Consequently, operators of public warehouses are concerned about the costs of constructing new storage compartments. This report contains designs and costs for four different types of compartments and a warehouse consisting of six separated compartments. The warehouse is designed for storing 40,000 to 50,000 bales and is suitable for areas of low rainfall, such as the Southwest. The main objective of this study was the development of improved floor layouts and building designs for cotton warehouses which would help to reduce the costs of handling bales of cotton and to minimize losses from fire and weather damage. This report is intended as a guide for planning public warehouses for storing cotton; it will not replace the services of engineers, architects, or builders.

description: A microscopic Hamiltonian for interacting manganese impurities in diluted magnetic semiconductors (DMS) is derived. It is shown that in p -type III-V DMS the indirect exchange between Mn impurities has similarities with the Zener mechanism in transition metal oxides. Here the mobile holes and localized states near the top of the valence band play the role of unoccupied oxygen orbitals which induce ferromagnetism. The Curie temperature estimated from the proposed kinematic exchange agrees with recent experiments on GaAs:Mn. The model is also applicable to the GaP:Mn system.

Resolving New Keynesian Anomalies with Wealth in the Utility Function

description: At the zero lower bound, the New Keynesian model predicts that output and inflation collapse to implausibly low levels, and that government spending and forward guidance have implausibly large effects. To resolve these anomalies, we introduce wealth into the utility function; the justification is that wealth is a marker of social status, and people value status. Since people partly save to accrue social status, the Euler equation is modified. As a result, when the marginal utility of wealth is sufficiently large, the dynamical system representing the zero-lower-bound equilibrium transforms from a saddle to a source---which resolves all the anomalies.
