description: For an automorphism $ϕ$ of a free group $F_n$ of rank $n$, Bestvina and Handel showed that the rank $rk Fix(ϕ)$ of the fixed subgroup is not greater than $n$ (the so-called Scott conjecture). Soon after Bestvina and Handel's announcement, their result was generalized by many authors in various directions. In this paper, we are interested in the fixed subgroups of endomorphisms of free products, focusing on explicit bounds for their ranks.

Fluid mechanics and thermal engineering not elsewhere classified

description: The performance of many objects is primarily dictated by the flow of surrounding air or water. For example, most of vehicle fuel usage is required to overcome aerodynamic drag. Conversely, the energy in flowing fluids can be harnessed as a renewable energy source. We can manipulate the flow around an object -- using, for example, pulsed jets of air or movement of the object surface -- to minimise vehicle drag or maximise energy generation. This thesis studies the control of flow around two generic geometries to provide insight into aerodynamic performance improvements across a broad range of engineering applications.

description: We have built regions in a Sky map where it should be expected the arrival of 120 EeV ultrahigh energy cosmic rays (UHECR) directionally correlated with the latest astrophysical neutrino tracks observed at IceCube, which are taken as point sources. In order to calculate these arrival directions we have considered contributions to the cosmic rays deflections originated by the galactic and the extragalactic magnetic field, and a UHECR composition compatible with the current expectations. We have used the Jansson-Farrar JF12 model for the Galactic magnetic field and an extragalactic magnetic field strength of 1nG and coherence length of 1Mpc. We observe that the regions outside of the Galactic plane are more strongly correlated with the neutrino tracks than those adjacent to or in it, with the former regions being good candidates to search for excesses, or anisotropies, in the UHECR flux. Additionally, we have focused, as an example, on the region of 150 EeV UHECR arrival directions correlated with the IceCube event 37 located at $(l,b)=(-137.1^\circ,65.8^\circ)$ in the Northern Hemisphere, far away from the Galactic plane, obtaining an angular size $\sim 5^\circ$, being $\sim 3^\circ$ for 200 EeV, and $\sim 8^\circ$ for 120 EeV. The results presented in this paper represent a useful UHECR excess search Sky map guide.

Effect of Extrusion Operating Conditions on Aflatoxin Reduction and Product Characteristics of Corn-Peanut Flakes
Creators: name: Molla, Aynadis
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: The study was conducted with the objective of reducing aflatoxin B1 (AFB1), B2 (AFB2), G1 (AFG1), and G2 (AFG2) as a function of extruder operating conditions such as initial moisture content of samples (17% and 21%) barrel temperature (140, 160, and 180 0C), and screw speed (150,200 and 250 rpm) when naturally contaminated composite of corn and fully defatted peanut meal (70/30 ratio) was extrusion-cooked to produce corn flakes. Factorial design was used to conduct the experiment. The amounts of aflatoxin in extruded and unextruded composite samples were measured by using high-performance liquid chromatography (HPLC). Accordingly, the effect of the operating conditions on the physicochemical properties (bulk density, expansion ratio, specific length, fresh product moisture content, water absorption index (WAI), water solubility index (WSI), water holding capacity (WHC), and sensory characteristics (hardness and crispness) on composite of corn and fully defatted peanut meal (70/30 ratio) was investigated. The collected data were subjected to analysis of variance using SPSS statistical soft ware. Extrusion-cooking was observed to reduce aflatoxin (AF) content, which ranged from 60% to 93% depending on the type of AF significantly (P<0.05). Temperature and screw speed had a significant effect on the reduction of AFB1, but moisture content was not found to be a significant factor affecting the levels of AFB1. Major reduction was found at highest temperature (160 0C), as AFB1 and AFB2 were more reduced at it. The water solubility index of extrudates increased with temperature, but decreased with feed moisture content. WAI increased with increased barrel temperature and moisture levels. As barrel temperature increased from 140 0C to 1800C, WAI increased from 4.810 to 5.799 respectively and it was increased from5.317 to 5.417 when moisture grew from 17% to 21 %. WSI increased from 10.641 to 11.798 when the barrel temperature grew from 140 0C to 180 0C. Feed moisture and WSI showed inverse relationship. Screw speed showed direct correlation with WSI, which is as screw speed increased from 150 rpm to 250 rpm, WSI increased by 10.404 to 12.394, respectively. WHC increased from 5.612 to 6.841 when the barrel temperature increase from 1400C to 1800C. As feed moisture content increased from 17% to 21% WHC increased from 6.244 to 6.483. The results indicated that this new product had good flavor and color than pure corn flakes, but it is less crispy. It had also over all acceptances greater than 5. In conclusion 1600C barrel x temperature, 17% moisture content and 150rpm screw speed has been found to be ideal operating variables for reducing aflatoxin and improving the quality of the corn-peanut flakes.

description: In this paper, we study the atomic structure of Puiseux monoids generated by monotone sequences. To understand this atomic structure, it is often useful to know whether the monoid has a bounded generating set. We provide necessary and sufficient conditions for the atomicity and boundedness to be transferred from a monotone Puiseux monoid to all its submonoids. Finally, we present two special subfamilies of monotone Puiseux monoids and fully classify their atomic structure.

Each of these subalgebras admits as a basis a $q$-analogue to Gessel's fundamental quasisymmetric functions where $q$ is equal to a complex root of unity. Interestingly, the basis elements are indexed by sets corresponding to an intermediary statistic between peak and descent sets of permutations that we call extended peak.

description: An infinite dimensional canonical symplectic structure and structure-preserving geometric algorithms are developed for the photon-matter interactions described by the Schrödinger-Maxwell equations. The algorithms preserve the symplectic structure of the system and the unitary nature of the wavefunctions, and bound the energy error of the simulation for all time-steps. This new numerical capability enables us to carry out first-principle based simulation study of important photon-matter interactions, such as the high harmonic generation and stabilization of ionization, with long-term accuracy and fidelity.

On Helium Mixing in Quasi-global Simulations of the Intracluster Medium

description: The assumption of a spatially uniform helium distribution in the intracluster medium can lead to biases in the estimates of key cluster parameters if composition gradients are present. The helium concentration profile in galaxy clusters is unfortunately not directly observable. Current models addressing the putative sedimentation are one-dimensional and parametrize the presence of magnetic fields in a crude way, ignoring the weakly-collisional, magnetized nature of the medium. When these effects are considered, a wide variety of instabilities can play an important role in the plasma dynamics. In a series of recent papers, we have developed the local, linear theory of these instabilities and addressed their non-linear development with a modified version of Athena. Here, we extend our study by developing a quasi-global approach that we use to simulate the mixing of helium as induced by generalizations of the heat-flux-driven buoyancy instability (HBI) and the magneto-thermal instability (MTI), which feed off thermal and composition gradients. In the inner region of the ICM, mixing can occur on few Gyrs, after which the average magnetic field inclination angle is $\sim 45^{\circ}$ resulting in an averaged Spitzer parameter higher by about 20 % than the value obtained in homogeneous simulations. In the cluster outskirts the instabilities are rather inefficient, due to the shallow gradients. This suggests that compositions gradients in cluster cores might be shallower than one-dimensional models predict. More quantitative statements demand more refined models that can incorporate the physics driving the sedimentation process and simultaneously account for the weakly-collisional nature of the plasma.

description: El aceite esencial presente en la cáscara de pomelo (Citrus maxima) procedente de la región Caribe de Colombia, se extrajo del exocarpo del fruto, utilizando los métodos de destilación por arrastre con vapor e hidrodestilación, con el fin de comparar los rendimientos de la extracción y optimizar las condiciones de obtención de los métodos antes mencionados. Los métodos de extracción fueron comparados teniendo en cuenta el rendimiento de la extracción a partir de variables influyentes como el tiempo y el tamaño de partícula, lo cual permitió determinar el mejor de los métodos. El mejor rendimiento (0,182 %) se registró para el método de destilación por arrastre con vapor. Del mismo modo, se observó que el tamaño de partícula es la variable de mayor incidencia en el rendimiento de la extracción con destilación por arrastre con vapor, mientras que para el método de hidrodestilación, el tiempo y el tamaño de tamaño de partícula fueron las más significativas. La optimización de las condiciones de extracción para cada uno de los métodos se realizó por medio de un análisis estadístico usando superficies de respuestas, las cuales permitieron definir que el proceso de destilación por arrastre con vapor debe realizarse por un tiempo de extracción de 66,21 min y con un tamaño de partícula de 0,59 cm para obtener un rendimiento del 0,182%, mientras que el proceso de hidrodestilación se debe realizar durante un tiempo de 46,42 min y con un tamaño de partícula de 1,94 cm, condiciones con las cuales se obtendría un rendimiento del 0,033%.

description: Several corrosion resistant alloys, with chromium (Cr) as a key functional alloying element, are now commodity metallic materials presently being used in a myriad of applications. Yet, several fundamental aspects of so-called ‘Cr-based passivity’ are not fully understood due to a lack of element-resolved information. This thesis advances our knowledge of the underlying mechanisms and the associated rate controlling factors of passivity in Cr and Cr-containing alloys. The findings herein will guide design of new corrosion resistant alloys for application in harsh corrosive environments and for emerging technologies

description: This paper proposes a multi-level feature learning framework for human action recognition using a single body-worn inertial sensor. The framework consists of three phases, respectively designed to analyze signal-based (low-level), components (mid-level) and semantic (high-level) information. Low-level features capture the time and frequency domain property while mid-level representations learn the composition of the action. The Max-margin Latent Pattern Learning (MLPL) method is proposed to learn high-level semantic descriptions of latent action patterns as the output of our framework. The proposed method achieves the state-of-the-art performances, 88.7%, 98.8% and 72.6% (weighted F1 score) respectively, on Skoda, WISDM and OPP datasets.

description: La problemática del desplazamiento forzado en Colombia se materializa con el abandono de las personas de su terruño, obligadas por el conflicto armado interno, originando persecuciones y la violación de los derechos humanos. En el caso de la mujer sufre un impacto diferencial de la violencia armada debido a que, cuando se producen las distintas eventualidades como: atracos, violaciones, torturas, desplazamiento forzado, desaparición y otros, que se ciernen sobre ellas, las sobrevivientes deben afrontar nuevas responsabilidades, serios obstáculos y graves implicaciones psicológicas. Autores como Lozano y Gómez (2015), afirman que el desplazamiento forzado producido por violencia, genera en las mujeres, un impacto negativo en su psique, al punto de presentar conductas suicidas, angustia, fobia social, trastornos de ansiedad generalizada, entre otras. Por lo anterior, esta investigación busca, determinar el impacto psicológico producido por el desplazamiento forzado sobre las mujeres víctimas, ubicadas en el barrio ciudad del bicentenario Cartagena, profundizando en la evolución del proceso de duelo, lo cual servirá como base de conocimiento para brindar tratamiento psicológico acorde a las necesidades de esta comunidad. En el plano metodológico, el tipo de investigación fue cualitativa interpretativa bajo el paradigma constructivista, con enfoque ideográfico. La población está constituida por 350 mujeres víctimas de desplazamiento forzado ubicadas en el barrio Bicentenario de la ciudad de Cartagena, en cuanto al muestreo, fue no probabilístico; para lo cual se seleccionaron 50 mujeres, las cuales fueron elegidas por conveniencia según características definidas por el investigador.

description: Expected to be of the highest survey power telescope in the northern hemisphere, the Wide Field Survey Telescope (WFST) will begin its routine observations of the northern sky since 2023. WFST will produce a lot of scientific data to support the researches of time-domain astronomy, asteroids and the solar system, galaxy formation and cosmology and so on. We estimated that the 5 $σ$ limiting magnitudes of WFST with 30 second exposure are $u=22.31$ mag, $g=23.42$ mag, $r=22.95$ mag, $i=22.43$ mag, $z=21.50$ mag, $w=23.61$ mag. The above values are calculated for the conditions of $airmass=1.2$, seeing = 0.75 arcsec, precipitable water vapour (PWV) = 2.5 mm and Moon-object separation = $45^{\circ}$ at the darkest New Moon night of the Lenghu site (V=22.30 mag, Moon phase $θ=0^{\circ}$). The limiting magnitudes in different Moon phase conditions are also calculated. The calculations are based on the empirical transmittance data of WFST optics, the vendor provided CCD quantum efficiency, the atmospherical model transmittance and spectrum of the site. In the absence of measurement data such as sky transmittance and spectrum, we use model data.

A functional model of non-suicidal self-injury in real-time
Creators: name: Siegel, David Marc
Publisher: name: No Publisher Supplied
Year: 2023

description: Only a limited body of research exists to apply a developmental perspective to explain why non-suicidal self-injury (NSSI) peaks during adolescence. The current study employs the Experiential Avoidance Model to address this gap. The Experiential Avoidance Model posits that NSSI functions to provide temporary relief from overarousal. Consistent with this well- established theory, two closely related, manifestations of overarousal – agitation and insomnia – have been found to be associated with NSSI. However, few studies have examined agitation and insomnia among adolescents, and even fewer have utilized ecologically valid approaches. Thus, the current study employed ecological momentary assessment (EMA) to evaluate the hypotheses that elevated levels of agitation would be associated with NSSI urges and behaviors, and that these associations would be stronger for adolescents who also experience insomnia. Over the EMA period, a sample of 123 late adolescents reported on three daily occasions their levels of agitation and insomnia, as well as NSSI urges and behaviors. Results of the study indicated that agitation was significantly associated with the presence and frequency of NSSI behaviors and urges, after controlling for NSSI behaviors and thoughts over the past month, respectively. Further, the effect size (e.g., steepness of slope) of the relationships between agitation and the presence and frequency of NSSI urges was stronger among individuals who also reported lower levels of insomnia, after controlling for NSSI thoughts over the past month. Our findings increase support for the Experiential Avoidance Model and suggest future research investigate the role of agitation in NSSI.

description: Quantum mechanical calculations for material modelling using Kohn-Sham density functional theory (DFT) involve the solution of a nonlinear eigenvalue problem for $N$ smallest eigenvector-eigenvalue pairs with $N$ proportional to the number of electrons in the material system. These calculations are computationally demanding and have asymptotic cubic scaling complexity with the number of electrons. Large-scale matrix eigenvalue problems arising from the discretization of the Kohn-Sham DFT equations employing a systematically convergent basis traditionally rely on iterative orthogonal projection methods, which are shown to be computationally efficient and scalable on massively parallel computing architectures. However, as the size of the material system increases, these methods are known to incur dominant computational costs through the Rayleigh-Ritz projection step of the discretized Kohn-Sham Hamiltonian matrix and the subsequent subspace diagonalization of the projected matrix. This work explores the potential of polynomial expansion approaches based on recursive Fermi-operator expansion as an alternative to the subspace diagonalization of the projected Hamiltonian matrix to reduce the computational cost. Subsequently, we perform a detailed comparison of various recursive polynomial expansion approaches to the traditional approach of explicit diagonalization on both multi-node CPU and GPU architectures and assess their relative performance in terms of accuracy, computational efficiency, scaling behaviour and energy efficiency.

description: We consider Lagrangian coherent structures (LCSs) as the boundaries of material subsets whose advective evolution is metastable under weak diffusion. For their detection, we first transform the Eulerian advection-diffusion equation to Lagrangian coordinates, in which it takes the form of a time-dependent diffusion or heat equation. By this coordinate transformation, the reversible effects of advection are separated from the irreversible joint effects of advection and diffusion. In this framework, LCSs express themselves as (boundaries of) metastable sets under the Lagrangian diffusion process. In the case of spatially homogeneous isotropic diffusion, averaging the time-dependent family of Lagrangian diffusion operators yields Froyland's dynamic Laplacian. In the associated geometric heat equation, the distribution of heat is governed by the dynamically induced intrinsic geometry on the material manifold, to which we refer as the geometry of mixing. We study and visualize this geometry in detail, and discuss connections between geometric features and LCSs viewed as diffusion barriers in two numerical examples. Our approach facilitates the discovery of connections between some prominent methods for coherent structure detection: the dynamic isoperimetry methodology, the variational geometric approaches to elliptic LCSs, a class of graph Laplacian-based methods and the effective diffusivity framework used in physical oceanography.

Norm-Based Enforcement of Promises
Creators: name: Stone, Rebecca

Publisher: name: Zenodo
Year: 2020

description: There is ample evidence that people are internally motivated to keep their promises. However, it is unclear whether promises alone create a meaningful level of commitment in many economically relevant situations where the stakes are high. In a between-subject design, we ask subjects to imagine they observed as third parties a promisor breaking her promise and could punish the promisor, at a cost to themselves, for her behavior. Our results suggest that the motivations third parties have to punish promise breakers have the same structure as the moral motivations of those deciding whether or not to keep their promises. That is, the same moral reasons that motivate promisors to keep their promises make third-party observers more likely to punish promise breaking. This suggests that the determinants of promise-keeping behavior will also drive non-legal enforcement mechanisms in relational contract settings and situations where third parties can punish promisors in a decentralized fashion, such that the moral forces of promise keeping can generate commitment even when the stakes are high.

description: We study the mixed-state entanglement for AdS Born-Infeld (BI) theory. We calculate the mixed-state entanglement and investigate the relationship between it and the system parameters. We find that the holographic entanglement entropy (HEE) and mutual information (MI) exhibit monotonically increasing and decreasing behavior with BI factor $b$. However, the entanglement wedge cross-section (EWCS) exhibits a very rich set of phenomena about system parameters. EWCS always increases with $b$ when $b$ is small and then monotonically decreases with $b$. These behaviors suggest that increasing the BI factor, which is essentially enhancing the coupling between the background geometry and the transport properties can always enhance the EWCS. The coupling between the entanglement and the transport behaviors has also been studied in condensed matter theories and is important to construct a stable quantum circuit. We also provide analytical understanding of the above phenomenon. Furthermore, we have tested two additional BI-like models and find the universality of these results, suggesting the crucial role of the BI term in governing the interplay between nonlinear electromagnetic effects and entanglement.

Year: 2019

description: The purpose of this research was to investigate; the effect of reward practices on employee motivation in Heineken Brewery S.C. Heineken has financial and nonfinancial reward system in place as a means of motivating and retaining employee. But the problem is the company has not conducted a study to measure which type of reward scheme is appropriate and which is not. In time, these might highly impact organizational effectiveness and excellence. In addition, the staffs have a number of problems associated with financial and non-financial rewards provided by the company. Meanwhile, subsequent problems have been observed in the company, according to human resource annual report issue related with reward practices de-motivated employee turnover have been recorded. The study used both primary and secondary sources of data. A quantitative research approach of data collection was used and 183 questionnaires were distributed out of which 153 of them were returned. Probability sampling (stratified) method was used and employees were selected from each stratum with a random sampling technique. Among the major findings, the overall perception of respondents over current reward practices were not happy, not enough, not competitive and not attractive. on other side the ranking orders as respondents choice of the most motivator factors from the list, payment is the highest influential factor for employee motivation followed by promotion, benefits, recognition working condition and job security respectively, The result of correlation shows that; there exist positive and significant relation between payment, promotion, benefit, recognition, job security & working condition and employee motivation. On other side, the result of regression analysis shows that; payment and promotion have high explanatory of employee motivation. On top of that, a significant portion of employees considered the reward practices in Heineken Brewery S.C. as less motivating, unfair, not competitive and attractive and hence employees seemed to be less responsibility, less loyalty and belongingness and less committed to the organization. It is recommended to review the company current reward practice that are factor that affect employees motivation

description: Petroleum-derived plastics are the top choice as packaging materials, however, most of the plastics are used for only a few days and then discarded, causing a serious environmental concern. Spray deposited nanocellulose films has emerged as potential alternative to conventional packaging; but long drying times, limited moisture barrier performance and high energy consumptions are the major challenges associated with their future use. The aim of this thesis is to highlight and overcome these issues with the utilization of spray deposited nanocellulose films and thus inching closer to substituting conventional plastic packaging.

A first analysis of the ensemble of local maxima of maximal center gauge

description: Maximal center gauge (MCG) aims to detect some of the most important vacuum configurations, suggesting thick magnetic flux tubes quantised to non-trivial center elements of the gauge group being responsible for confinement. Due to the NP-hardness of a global maximization of the gauge functional only numeric procedures aiming for local maxima are possible. We observe a linear decrease of the string tension with increasing gauge functional value of the local maxima. This implies that the request to get as close as possible to the absolute maximum is untainable. We compare global properties of the ensemble of local maxima with other methods to detect center vortices and with determinations of the string tension from full configurations. This comparison indicates that the information about the number and positions of center vortices is contained in the structure of the ensemble of local maxima. This may pave the way for a future more successful formulation of the gauge condition.

Publisher: name: Monash University
Year: 2022
Subjects: Clinical microbiology

description: Degenerative Disc Disease is a complicated condition affecting the lumbar region due to difficulties in identification of the condition at early stages. This thesis develops a robust and novel predictive disc degeneration analysis model to provide greater knowledge on disc degeneration and corresponding effects on stresses in the lumbar spine. Artificial intelligence is utilized for accurate prediction of stresses at specific levels of degeneration. The results from this work may benefit clinicians in providing quick and timely diagnosis and the corresponding remedy based on the severity of the condition, thus preventing further damage to a patient’s spine.

description: Mixing two chemical elements at the surface of a substrate is known to produce rich phase diagrams of surface alloys. Here, we extend the concept of surface alloying to the case where the two constituent elements are not both atoms, but rather one atom (copper) and one molecule (fullerene). When deposited at room temperature on a Cu(111) surface, fullerenes intermix with the metal substrate. Surprisingly, 10 distinct copper-fullerene surface alloys are found to coexist. The structure of these alloys, i.e. their composition and commensurability relationship with the substrate, is resolved using scanning tunneling microscopy and density functional theory calculations. This diversity in the alloying process is associated to the multiple possibilities a fullerene can bind to the Cu surface. The molecules are indeed found to have in-plane and out-of-plane positional degree of freedom: the molecular alloys have elastic in-plane properties and can buckle. In addition, the molecules can rotate on their binding sites, conferring extra degrees of freedom to the system. We introduce a competing-interaction energy model, parametrized against the results of the \textit{ab initio} calculations, that describes well all the phases we observe experimentally.
