description: The Brazilian project Carne Carbono Neutro (CCN) assumes that a more sustainable beef will increase its value for the consumers. The paper aims to verify this assumption and to suggest a communication strategy supporting the CCN valorization. An online survey involving 506 Brazilian consumers showed three different classes of consumers with significantly different attitudes towards environmental issues. Price and quality always strongly influence their demand for beef. A communication campaign should focus on the CCN lower beef environmental impact and beef price/quality issues. Social media on internet and education programs in schools and different institutions should be used.

description: I study the effect of various types and amounts of North American Business language data on the quality of the derived vocabulary, and use my ﬁndings to derive an improved ranking of the words, using only 19% of the NAB corpus. I then study the conﬂicting effects of increased vocabulary size on a speech recognizer’s accuracy, and use the result to pick an optimal vocabulary size. A similar analysis of ngram coverage yields a very different outcome, with the best system being the one based on the most data.

description: This paper focuses on the study of a practical management problem faced by a healthcare {\it emergency department} (ED) located in the north of Italy. The objective of our study was to propose organisational changes in the selected ED, which admits approximately 7000 patients per month, aiming at improving key performance indicators related to patient satisfaction, such as the waiting time. Our study is based on a design thinking process that adopts a {\it discrete event simulation} (DES) model as the main tool for proposing changes. We used the DES model to propose and evaluate the impact of different improving scenarios. The model is based on historical data, on the observation of the current ED situation, and information obtained from the ED staff. The results obtained by the DES model have been compared with those related to the existing ED setting, and then validated by the ED managers. Based on the results we obtained, one of the tested scenarios was selected by the ED for implementation.

description: We extend the results of planetary formation synthesis by computing the long-term evolution of synthetic systems from the clearing of the gas disk into the dynamical evolution phase. We use the symplectic integrator SyMBA to numerically integrate the orbits of planets for 100 Ma, using populations from previous studies as initial conditions.We show that within the populations studied, mass and semi-major axis distributions experience only minor changes from post-formation evolution. We also show that, depending upon their initial distribution, planetary eccentricities can statistically increase or decrease as a result of gravitational interactions. We find that planetary masses and orbital spacings provided by planet formation models do not result in eccentricity distributions comparable to observed exoplanet eccentricities, requiring other phenomena such as e.g. stellar fly-bys to account for observed eccentricities.

description: We establish criteria on the chemotactic sensitivity $χ$ for the non-existence of global weak solutions (i.e. \textit{blow-up} in finite time) to a stochastic Keller--Segel model with spatially inhomogeneous, conservative noise on $\mathbb{R}^2$. We show that if $χ$ is sufficiently large then \emph{blow-up} occurs with probability $1$. In this regime our criterion agrees with that of a deterministic Keller--Segel model with increased viscosity. However, for $χ$ in an intermediate regime, determined by the variance of the initial data and the spatial correlation of the noise, we show that \emph{blow-up} occurs with positive probability.

description: Topic adaptation for language modeling is concerned with adjusting the probabilities in a language model to better reflect the expected frequencies of topical words for a new document. The language model to be adapted is usually built from large amounts of training text and is considered representative of the current domain. In order to adapt this model for a new document, the topic (or topics) of the new document are identified. Then, the probabilities of words that are more likely to occur in the identified topic(s) than in general are boosted, and the probabilities of words that are unlikely for the identified topic(s) are suppressed.

description: One of the core questions of quantum physics is how to reconcile the unitary evolution of quantum states, which is information-preserving and time-reversible, with evolution following the second law of thermodynamics, which, in general, is neither. The resolution to this paradox is to recognize that global unitary evolution of a multi-partite quantum state causes the state of local subsystems to evolve towards maximum-entropy states. In this work, we experimentally demonstrate this effect in linear quantum optics by simultaneously showing the convergence of local quantum states to a generalized Gibbs ensemble constituting a maximum-entropy state under precisely controlled conditions, while introducing an efficient certification method to demonstrate that the state retains global purity. Our quantum states are manipulated by a programmable integrated quantum photonic processor, which simulates arbitrary non-interacting Hamiltonians, demonstrating the universality of this phenomenon. Our results show the potential of photonic devices for quantum simulations involving non-Gaussian states.

description: Cananga essential oil is a type of oil extracted by distillation from freshly-picked cananga flowers. Cananga oil is of a high economic value for its use as fragrances and flavors. In Indonesia, cananga essential oil is majorly produced by small and medium distillers. The most prominent barrier to cananga essential oil production in Indonesia is the fluctuation in its price. This price fluctuation is responsible for the decrease in profits earned by distillers. The aim of this research was to develop a system dynamics model to maximize profits in the cananga essential oil production in Indonesia. A system dynamics approach was employed to figure out the effect of some variables on cananga essential oil production in relation to profits and the interaction of such variables with each other. The scenarios examined in this system dynamics model include to increase the number of distillers, to decrease the fuel expenses, and a combination of both. This research assumed that a change in parameter will be able to increase profits from the cananga essential oil production in Indonesia over the next five years. The results show that increasing the number of distillers and decreasing the fuel expenses have been able to increase cananga essential oil production average by 20% and profits by 62%.

description: This study deals with the consumers' perceived risk and its determinants for fresh tomatoes in Albania. Survey data are analyzed using ordered logistic regression.Consumers associate a high level of benefits with the consumption of fresh tomatoes but have severe doubts about food safety and rate the average level of food safety risk as high as 6.66 on a scale from 0 to 10.Consumers' knowledge of food safety, their perceptions about the reliability of food safety information, the government's ability to ensure safety, negative experiences with tomato consumption, consumer age, and family size are key determinants of perceived food risk, while gender, education, and income did not prove to be significant. The results provide the basis for appropriate actions by government and food system actors in improving food safety and consumers‘ trust in food safety assurance.

Subjects: food waste; food waste knowledge; consumer behavior; social desirability bias; consumer survey

description: In times of increasing environmental awareness, the topic of food waste receives a lot of attention from practitioners and scholars alike. In this study, we analyze how well-informed Austrian consumers regard food waste and what factors might influence this knowledge. In a consumer survey (n = 470), we examined consumer food and food handling knowledge, cooking skills, place of residence, personal ties to agriculture, engagement in initiatives against food waste, and their effect on food waste knowledge. To understand what effect social desirability might have on participants’ answers, we administered the survey in both online and face-to-face settings. Amongst others, our findings suggest a positive relationship between knowledge about food and food handling and knowledge about food waste prevention as well as a social desirability bias in reporting one’s own knowledge about food waste prevention. We could not find a statistically significant relationship between food and food handling knowledge, and food waste knowledge. Furthermore, we did not find evidence that a personal connection to agriculture or a rural place of residence leads to better food waste knowledge. Finally, the unexpected influence of cooking skills is at least surprising to a certain extent. We conclude this study by outlining potential areas for future research as well as managerial implications.

description: The SDSS-III/APOGEE survey operated from 2011-2014 using the APOGEE spectrograph, which collects high-resolution (R~22,500), near-IR (1.51-1.70 microns) spectra with a multiplexing (300 fiber-fed objects) capability. We describe the survey data products that are publicly available, which include catalogs with radial velocity, stellar parameters, and 15 elemental abundances for over 150,000 stars, as well as the more than 500,000 spectra from which these quantities are derived. Calibration relations for the stellar parameters (Teff, log g, [M/H], [alpha/M]) and abundances (C, N, O, Na, Mg, Al, Si, S, K, Ca, Ti, V, Mn, Fe, Ni) are presented and discussed. The internal scatter of the abundances within clusters indicates that abundance precision is generally between 0.05 and 0.09 dex across a broad temperature range; within more limited ranges and at high S/N, it is smaller for some elemental abundances. We assess the accuracy of the abundances using comparison of mean cluster metallicities with literature values, APOGEE observations of the solar spectrum and of Arcturus, comparison of individual star abundances with other measurements, and consideration of the locus of derived parameters and abundances of the entire sample, and find that it is challenging to determine the absolute abundance scale; external accuracy may be good to 0.1-0.2 dex. Uncertainties may be larger at cooler temperatures (Teff<4000K). Access to the public data release and data products is described, and some guidance for using the data products is provided.

as PlanetLab, EmuLab, IBM/Google cluster, and Amazon
EC2/S3, that enable researchers to study different aspects
of distributed computing. However, no single testbed
supports research spanning systems, applications,
services, open-source development, and datacenters.
Towards this end, we have developed Open Cirrus, a
cloud computing testbed for the research community that
federates heterogeneous distributed data centers. Open
Cirrus offers a cloud stack consisting of physical and
virtual machines, and global services, such as sign-on,
monitoring, storage, and job submission. By developing
the testbed and making it available to the research
community, we hope to help spur innovation in cloud
computing and catalyze the development of an open

description: Autonomous mobile ground robots use global and local path planners to determine the routes that they should follow to achieve mission goals while avoiding obstacles. Although many path planners have been developed, no single one is best for all situations. This paper describes metareasoning approaches that enable a robot to select a new path planning algorithm when the current planning algorithm cannot find a feasible solution. We implemented the approaches within a ROS-based autonomy stack and conducted simulation experiments to evaluate their performance in multiple scenarios. The results show that these metareasoning approaches reduce the frequency of failures and reduce the time required to complete the mission.

Here we describe a new approach that avoids the current limitations by combining strong non-linearities with active Gaussian operations in efficient protocols for Bell state analysers and Controlled-Sign gates.

description: This paper considers the problem of controlling a dynamical system when the state cannot be directly measured and the control performance metrics are unknown or partially known. In particular, we focus on the design of data-driven controllers to regulate a dynamical system to the solution of a constrained convex optimization problem where: i) the state must be estimated from nonlinear and possibly high-dimensional data; and, ii) the cost of the optimization problem -- which models control objectives associated with inputs and states of the system -- is not available and must be learned from data. We propose a data-driven feedback controller that is based on adaptations of a projected gradient-flow method; the controller includes neural networks as integral components for the estimation of the unknown functions. Leveraging stability theory for perturbed systems, we derive sufficient conditions to guarantee exponential input-to-state stability (ISS) of the control loop. In particular, we show that the interconnected system is ISS with respect to the approximation errors of the neural network and unknown disturbances affecting the system. The transient bounds combine the universal approximation property of deep neural networks with the ISS characterization. Illustrative numerical results are presented in the context of control of robotics and epidemics.

description: Based on density functional theory calculations, the structural and electronic properties of polythiophene in periodic and oligomer forms have been investigated. In particular, the effects of Li or Cl adsorption onto a monolayer and Li or Cl-intercalation into bulk or bilayer polythiophene are addressed using periodic calculations. The binding energy of Li or Cl adsorbed bulk or bilayer polythiophene is significantly larger than for the monolayer. The trends in the binding energy as a function of adsorbent remain the same for both the periodic and molecular cases. The band gap or HOMO-LUMO gap and charge transfer are analysed. In addition, for the bulk or bilayer, different kinds of stacking have been considered. It is found that the parallel bulk or bilayer structure is energetically favorable compared to flipping the second layer by 180$^\circ$. This has been considered for both the periodic and oligomer forms. Moreover, for Li adsorption, polarons are found to be more stable than bipolarons, while the situation is opposite for Cl adsorption. The detailed analysis of the present study will be useful for understanding the structural properties and the tuneability of the electronic states, which is an important step to construct polythiophene based electronic devices.

The characteristic signatures appear in the single-particle excitation spectrum. We show that the transitions are governed by a "many-body selection rule" which allows one to relate the number of allowed transitions to the number of quasihole states on a finite geometry. We illustrate the theory with numerically exact simulations of small numbers of particles.

Smooth norms in dense subspaces of $\ell_p(Γ)$ and operator ranges

description: For $1\leq p<\infty$, we prove that the dense subspace $\mathcal{Y}_p$ of $\ell_p(Γ)$ comprising all elements $y$ such that $y \in \ell_q(Γ)$ for some $q \in (0,p)$ admits a $C^{\infty}$-smooth norm which locally depends on finitely many coordinates. Moreover, such a norm can be chosen as to approximate the $\left\Vert\cdot \right\Vert_p $-norm. This provides examples of dense subspaces of $\ell_p(Γ)$ with a smooth norm which have the maximal possible linear dimension and are not obtained as the linear span of a biorthogonal system. Moreover, when $p>1$ or $Γ$ is countable, such subspaces additionally contain dense operator ranges; on the other hand, no non-separable operator range in $\ell_1(Γ)$ admits a $C^1$-smooth norm.

description: We prove that, for any type III$_1$ free product factor, its continuous core is full if and only if its $τ$-invariant is the usual topology on the real line. This trivially implies, as a particular case, the same result for free Araki--Woods factors. Moreover, our method shows the same result for full (generalized) Bernoulli crossed product factors of type III$_1$.

description: While human-computer interaction (HCI) methodologies are designed to be general, they have most often been applied in the context of literate end users in the West. These methodologies may, however, need rethinking for application in HCI for the developing world (HCID) contexts, where many of the basic assumptions that underpin the methods may not always hold true. In this article, we present an overview of one factor that is significantly different in the
HCID context—the literacy of the end user—by drawing on the literature of orality, and we offer a framework for HCID methodology that we argue is more appropriate for the HCID context. Based on this framework, we then present guidelines for design and user research methodologies in such contexts, highlighting seminal HCID research that corroborates these guidelines.

description: Understanding how information about external stimuli is transformed into behavior is one of the central goals of neuroscience. Here we characterize the information flow through a complete sensorimotor circuit: from stimulus, to sensory neurons, to interneurons, to motor neurons, to muscles, to motion. Specifically, we apply a recently developed framework for quantifying information flow to a previously published ensemble of models of salt klinotaxis in the nematode worm C. elegans. The models are grounded in the neuroanatomy and currently known neurophysiology of the worm. The unknown model parameters were optimized to reproduce the worm's behavior. Information flow analysis reveals several key principles underlying how the models operate: (1) Interneuron class AIY is responsible for integrating information about positive and negative changes in concentration, and exhibits a strong left/right information asymmetry. (2) Gap junctions play a crucial role in the transfer of information responsible for the information symmetry observed in interneuron class AIZ. (3) Neck motor neuron class SMB implements an information gating mechanism that underlies the circuit's state-dependent response. (4) The neck carries non-uniform distribution about changes in concentration. Thus, not all directions of movement are equally informative. Each of these findings corresponds to an experimental prediction that could be tested in the worm to greatly refine our understanding of the neural circuit underlying klinotaxis. Information flow analysis also allows us to explore how information flow relates to underlying electrophysiology. Despite large variations in the neural parameters of individual circuits, the overall information flow architecture circuit is remarkably consistent across the ensemble, suggesting that information flow analysis captures general principles of operation for the klinotaxis circuit.

title: Factors influencing variation in face processing
Creators: name: Alharbi, Sarah
Publisher: name: University of Glasgow
Year: 2022

description: Perceptions of faces, such as judgments about others’ emotional states or attractiveness from facial characteristics, influence social interaction. However, relatively few studies have investigated factors that predict variation among individuals or groups of individuals in how people perceive facial characteristics and results from studies on this topic that have been reported have often been subsequently shown to not be robust. For these reasons, the studies reported in this thesis investigated potential sources of variation in face perception, focusing on (1) the relationship between affective factors and perceptions of facial expression of emotion in a UK sample and (2) the effects of sexually dimorphic face-shape characteristics on social judgments of faces in samples of Arab women. Chapter 2 (the first empirical chapter) reports results from a Registered Report investigating relationships between different affective factors and emotion perception. Results replicated previous studies suggesting that participants scoring higher on generalised anxiety performed poorer on emotion perception tasks, but also found evidence that other affective factors, particularly those related to empathy, also contributed to variation in emotion perception. While Chapter 2 had investigated responses to facial characteristics that can change very rapidly (emotional expressions), Chapters 3 and 4 investigated Arab women’s responses to a facial characteristic that is relatively stable over time (sexually dimorphic face-shape characteristics). Results from this series of studies suggested that Arab women perceived feminised versions of men’s faces to be more attractive, younger-looking, and less dominant than masculinised versions, but found no effects of sexually dimorphic face-shape characteristics on perceptions of men’s trustworthiness or health. These results for Arab women’s face perceptions show some similarities (e.g., femininized faces look more attractive, younger, and less dominant than masculinised faces) to results previously reported for UK women’s face perceptions, but also show some differences (e.g., UK women typically find feminized faces look more trustworthy, a pattern not seen in this sample of Arab women). Together, the results reported in this thesis suggest that affective factors and cultural differences may contribute to variation in face perceptions and highlight the importance of considering variation when studying face perception.
Ethnic identity, language, and /o/ fronting among Latinos at UNC Chapel Hill
Creators: name: McGee, Victoria
Publisher: name: University of North Carolina at Chapel Hill
Year: 2010

description: This study focuses on the variety of English used by college students at UNC Chapel Hill who self-identify as Latino and the relationship between the social and linguistic categories governing the speech of this particular group. The study will reveal, through conversations, interviews and questionnaires, certain details pertaining to the creation and expression of ethnic identity, which allows each speaker to orient themselves socially within the complex matrix of a college campus. The linguistic analysis of the study involves obtaining measurements of the F2 values of /o/ of Latino English speaking university students at UNC Chapel Hill at various grade levels and analyzing these measurement statistically in order to determine patterns that explain the connection between /o/ fronting and ethnic identity.
Capacities of the covariant Pauli channel

Publisher: name: arXiv
Year: 2022
Subjects: subject: Quantum Physics (quant-ph)

description: We study the four well-known capacities of a two-parameter family of qubit Pauli channels. These are the channels which are covariant under the SO(2) group and contain the depolarizing channel as a special case. We find exact expressions for the classical capacity and entanglement assisted capacities, and analytically determine the regions where the quantum capacity of the channel vanishes. We then use a flag extension to find upper bound for the quantum capacity and private capacity of these channels in the entire region of parameter space and also obtain the lower bound for the quantum capacity by calculating the single shot quantum capacity numerically. In conjunction with previous results on depolarizing channels, our result is one step forward for determining the capacities of the full Pauli channel.

description: Our algorithm, ParaMor, fared well in Morpho Challenge 2007 (Kurimo et al., 2007), a peer operated
competition pitting against one another algorithms designed to discover the morphological structure of
natural languages from nothing more than raw text. ParaMor constructs sets of affixes closely mimicking
the paradigms of a language, and, with these structures in hand, annotates word forms with morpheme
boundaries. Of the four language tracks in Morpho Challenge 2007, we entered ParaMor in English
and German. Morpho Challenge 2007 evaluated systems on their precision, recall, and balanced F1
at identifying morphological processes, whether those processes mark derivational morphology or inflectional
features. In English, ParaMor’s balanced precision and recall outperform at F1 an already sophisticated
baseline induction algorithm, Morfessor (Creutz, 2006). ParaMor placed fourth in English
overall. In German, ParaMor suffers from a low morpheme recall. But combining ParaMor’s analyses
with analyses from Morfessor results in a set of analyses that outperform either algorithm alone, and
that place first in F1 among all algorithms submitted to Morpho Challenge 2007

description: We consider models of identical pulse-coupled oscillators with global interactions. Previous work showed that under certain conditions such systems always end up in sync, but did not quantify how small clusters of synchronized oscillators progressively coalesce into larger ones. Using tools from the study of aggregation phenomena, we obtain exact results for the time-dependent distribution of cluster sizes as the system evolves from disorder to synchrony.
