Approximating smooth, multivariate functions on irregular domains

description: In this paper, we introduce a method known as polynomial frame approximation for approximating smooth, multivariate functions defined on irregular domains in $d$ dimensions, where $d$ can be arbitrary. This method is simple, and relies only on orthogonal polynomials on a bounding tensor-product domain. In particular, the domain of the function need not be known in advance. When restricted to a subdomain, an orthonormal basis is no longer a basis, but a frame. Numerical computations with frames present potential difficulties, due to the near-linear dependence of the truncated approximation system. Nevertheless, well-conditioned approximations can be obtained via regularization, for instance, truncated singular value decompositions. We comprehensively analyze such approximations in this paper, providing error estimates for functions with both classical and mixed Sobolev regularity, with the latter being particularly suitable for higher-dimensional problems. We also analyze the sample complexity of the approximation for sample points chosen randomly according to a probability measure, providing estimates in terms of the corresponding \textit{Nikolskii inequality} for the domain. In particular, we show that the sample complexity for points drawn from the uniform measure is quadratic (up to a log factor) in the dimension of the polynomial space, independently of $d$, for a large class of nontrivial domains. This extends a well-known result for polynomial approximation in hypercubes.

description: The increased demand for tighter border and building security has renewed public interest in biometric identification and verification systems. With fingerprint recognition being socially stigmatized, hand geometry-based recognizers have emerged as niche solutions. However, systems currently available in the marketplace require direct contact with the device, raising, among others, significant hygiene concerns. In this paper we introduce a novel approach to hand geometrybased identification. The proposed method employs Active Appearance Models to track the hand inside the capture device and to extract geometry features for identification. The AAM fitting algorithm runs faster than real-time, enabling robust system performance. In experiments on a small-scale database of hand images, the accuracy of our system exceeds 90% using as little as five features.

Entering the Borderland: Creative Process and the Quest for Mythic Resonance in the Work of an Australian Screenwriter

description: This exegesis explores the challenges I have faced as an emerging Australian storyteller attempting to write myths for domestic and international television audiences. The exegesis focuses specifically on four creative modalities that I have either developed or adopted in order to gain a better understanding of myth’s foundations, the archetypes. These modalities are: meditation, hypnagogic immersion, archetypal dream work and active imagination. The exegesis considers the hypothesis that an emerging screenwriter can gain a more instinctual and intimate understanding of myth from a ‘direct’ dialogue with the archetypes within one’s own body, than can be garnered solely through an intellectual understanding of the mythic storytelling frameworks that have been popularised within the screen industries. The creative works with which I’ve developed and tested this hypothesis include two short films Interview (2006) and The Weight of Sunken Treasure (2007), and the pilot script for Borderland, a proposed 10 episode serial drama for television.

title: Perspectives on Participation in Continuous Vocational Education Training–An Interview Study
Creators: name: Siegfried, Christin

Year: 2024

description: In European industrialized countries, a large number of companies in the healthcare, hotel, and catering sectors, as well as in the technology sector, are affected by demographic, political, and technological developments resulting in a greater need of skilled workers with a simultaneous shortage of skilled workers (CEDEFOP, 2015, 2016). Consequently, employers have to address workers who have not been taken into account such as low-skilled workers, workers returning from a career break, people with a migrant background, older people, and jobseekers and train them, in order to guarantee the professionalization of this workforce (Festing and Harsch, 2018). Continuing vocational education and training (CVET) is seen as an indispensable tool; because CVET has advantages for both employers and employees, it helps to increase the productivity of companies (Barrett and O’Connell, 2001), to prevent the widening of socioeconomic disparities (Dieckhoff, 2007), and to open up career opportunities for the workforce (Rubenson and Desjardins, 2009). However, participation rate on CVET seems to differ, depending on institutional factors (such as sector and size of the company) and individual characteristics (such as qualification level, migration background, age and time of absence from work) (e.g., Rubenson and Desjardins, 2009; Wiseman and Parry, 2017). In contrast to previous research, our study aims to provide a holistic view of reasons for and against CVET, combining the different perspectives of employers and (potential) employees. The analysis of reasons and barriers was carried out based on semi-structured interviews. Fifty-seven employers, 73 employees, and 42 jobseekers (potential employees) from the sectors retail, healthcare and social services, hotels and catering, and technology were interviewed. Results point to considerable differences in the reasons and barriers mentioned by the disadvantaged groups. These differences are particularly significant between employees on the one side and employers, as well as jobseekers, on the other side, while the reasons to attend CVET of jobseekers are more similar to those of employers. The results can be used to tailor CVET more closely to the needs of (potential) employees and thus strengthen both the qualification and career opportunities of (potential) employees and the competitiveness and productivity of companies.

description: High bandwidth sensor feedback is necessary for pegorming precise manipulation tasks within imprecisely calibrated and dynamically varying environments. Force controlled manipulation is a common technique for compliantly contacting and manipulating uncertain environments. visual servoing is an eflective technique for guiding imprecisely calibrated manipulators with imprecisely calibrated camera-lens systems. These two types of manipulator feedback, force and vision, represent complementary sensing modalities: visual feedback provides information over a relatively large area of the workspace without requiring contact with the environment, and force feedback provides highly localized and precise information upon contact. This paper presents three different strategies which combine force and vision within the feedback loop of a manipulator; traded control; hybrid control; and shared control. These strategies can be used alone, or in concert with each other, depending on the manipulation task. A discussion of the types of tasks that beneJit from the strategies is included, as well as experimental results which show that the use of visual servoing to stably guide a manipulator simplij5e.s the force control problem by allowing low gain force control with relatively large stability margins.

description: Protein-protein interaction (PPI) network alignment is a canonical operation to transfer biological knowledge among species. The alignment of PPI-networks has many applications, such as the prediction of protein function, detection of conserved network motifs, and the reconstruction of species' phylogenetic relationships. A good multiple-network alignment (MNA), by considering the data related to several species, provides a deep understanding of biological networks and system-level cellular processes. With the massive amounts of available PPI data and the increasing number of known PPI networks, the problem of MNA is gaining more attention in the systems-biology studies. In this paper, we introduce a new scalable and accurate algorithm, called MPGM, for aligning multiple networks. The MPGM algorithm has two main steps: (i) SEEDGENERATION and (ii) MULTIPLEPERCOLATION. In the first step, to generate an initial set of seed tuples, the SEEDGENERATION algorithm uses only protein sequence similarities. In the second step, to align remaining unmatched nodes, the MULTIPLEPERCOLATION algorithm uses network structures and the seed tuples generated from the first step. We show that, with respect to different evaluation criteria, MPGM outperforms the other state-of-the-art algorithms. In addition, we guarantee the performance of MPGM under certain classes of network models. We introduce a sampling-based stochastic model for generating k correlated networks. We prove that for this model, if a sufficient number of seed tuples are available, the MULTIPLEPERCOLATION algorithm correctly aligns almost all the nodes. Our theoretical results are supported by experimental evaluations over synthetic networks.

description: We report on simultaneous optical and X-ray observations of the Seyfert galaxy, NGC3147. The XMM-Newton spectrum shows that the source is unabsorbed in the X-rays ($N_H<5\times10^{20}$ cm$^{-2}$). On the other hand, no broad lines are present in the optical spectrum. The origin of this optical/X-rays misclassification (with respect to the Unification Model) cannot be attributed to variability, since the observations in the two bands are simultaneous. Moreover, a Compton-thick nature of the object can be rejected on the basis of the low equivalent width of the iron K$α$ line ($\simeq130$ eV) and the large ratio between the 2-10 keV and the [OIII] fluxes. It seems therefore inescapable to conclude that NGC3147 intrinsically lacks the Broad Line Region (BLR), making it the first "true" Seyfert 2.

FSVM is an improved version of the classical SVM algorithm, incorporating measurement errors into the classification process; this is the first successful application of this algorithm in the astronomy. We created reliable catalogues of galaxies, stars and AGNs consisting of objects with MIR measurements, some of them with no optical counterparts. Some examples of identified objects are shown, among them O-rich and C-rich AGB stars.

description: We employ tools from the fields of symbolic computation and satisfiability checking---namely, computer algebra systems and SAT solvers---to study the Williamson conjecture from combinatorial design theory and increase the bounds to which Williamson matrices have been enumerated. In particular, we completely enumerate all Williamson matrices of even order up to and including 70 which gives us deeper insight into the behaviour and distribution of Williamson matrices. We find that, in contrast to the case when the order is odd, Williamson matrices of even order are quite plentiful and exist in every even order up to and including 70. As a consequence of this and a new construction for 8-Williamson matrices we construct 8-Williamson matrices in all odd orders up to and including 35. We additionally enumerate all Williamson matrices whose orders are divisible by 3 and less than 70, finding one previously unknown set of Williamson matrices of order 63.

description: This article focuses on the constellations of actors engaged in the food safety debate in Germany and the potential of civil society organizations for mobilization and politicization of the issue. In an exploratory case study we assess the structure of communication between these organizations by applying hyperlink analysis. Our study sheds light on the nature of the issue network and in particular on their linkages with media and political actors. We interpret communication network patterns with respect to civil society actors' opportunities to make food safety salient on the agenda and to mobilize around it and politicize it. In fact, our empirical study shows that the structure of linkages between civil society actors, media organizations and political actors in Germany offers favourable opportunities for making the food safety issue salient and for politicizing it in the offline world.
Search for Top Squark Production using Run 2 Data from the CMS Experiment at the LHC
Creators: name: Merritt, Anna Henckel
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The Standard Model of particle physics is an experimentally successful description of the fundamental building blocks and properties of the universe.
Yet some questions remain, with no candidates for dark matter or explanation for the masses and oscillations of neutrinos.
Even the addition of the Higgs raised more questions, as its measured mass implies an unnatural degree of precision in the corrections to its mass.
These corrections scale with the mass of the particle interacting with the Higgs, with the top quark giving the largest contribution within the Standard Model.
The addition of Supersymmetry would ameliorate this, providing supersymmetric partners for each Standard Model particle to help cancel out their corrections.
This dissertation presents a search for the top squark, supersymmetric partner to the top quark, using data from the CMS detector taken during the years 2016-2018.
The data were taken at a center-of-mass energy of 13 TeV and correspond to an integrated luminosity of 137 inverse femtobarns.
The search targets fully-hadronic final states of multiple different simplified signal models for both direct and gluino-mediated top squark production.
Discussion is also given to work on the CMS Level-1 Trigger Menu, both as part of the Menu Team and on a project to incorporate a neural network into the trigger menu.

description: We study numerically a class of non-topological solitons, the Q-balls, arising in supersymmetric extension of the Standard Model with low-energy, gauge-mediated symmetry breaking. % Taking into account the exact form of the supersymmetric potential giving rise to Q-balls, we find that there is a lower limit on the value of the charge $Q$ in order to make them classically stable: $Q \gtrsim 5 \times 10^2 Q_{\rm cr}$, where $Q_{\rm cr}$ is constant depending on the parameters defining the potential and can be in the range $1 \lesssim Q_{\rm cr} \lesssim 10^{8 ÷16}$.If $Q$ is the baryon number, stability with respect to the decay into protons requires $Q \gtrsim 10^{17} Q_{\rm cr}$, while if the gravitino mass is greater then $m_{3/2} \gtrsim 61 \MeV$, no stable gauge-mediation supersymmetric Q-balls exist. Finally, we find that energy and radius of Q-balls can be parameterized as $E \sim ξ_E Q^{3/4}$ and $R \sim ξ_R Q^{1/4}$, where $ξ_E$ and $ξ_R$ are slowly varying functions of the charge.

description: In an attempt to perform a national unduplicated accounting of visit patterns across domestic violence homeless shelters, while respecting the confidentiality of the clients who are the subjects of that accounting, the United States Department of Housing and Urban Development ("HUD") has sponsored locally administered Homeless Management Information Systems ("HMIS"). These are computerized data collection and processing systems designed to capture person-specific information over time from homeless persons being serviced by local shelters. In order to maintain client safety and to insure high degrees of compliance, HUD agreed that the name and Social Security number of each client of a domestic violence homeless shelter are not to be forwarded to HMIS. Instead, a newly created identifier termed a â€œunique identification number ("UID") can be used. A question posed is, "how do shelters construct UIDs with minimal risk of re-identification while still achieving an accurate unduplicated accounting?" The work reported herein provides a framework for reasoning about and assessing proposed technical solutions that may answer this question. Eight categories of technologies (encoding, hashing, encryption, scan cards/RFID, biometrics, consent, inconsistent hash, and distributed query) are examined and a set of recommendations provided. Results suggest that inconsistent hashing, distributed query and (regular) hashing may be easier to bundle with policies and best practices to create an effective solution. Scan cards, encryption, and biometrics create new kinds of risks to consider. Consent and encoding are technically the simplest to implement but harbor serious dangers that are difficult for any particular implementation to overcome. Biometrics is the only technology that authenticates clients; all the other technologies tend to rely on non-verified information from clients. While significant differences and tradeoffs exist in the use of these technologies, there is no magic technology as much as practices that must be bundled with any chosen technology in order to demonstrate minimal risk of client reidentification and maximum correctness in computing an unduplicated accounting.

description: Pathogens frequently associated with multi-drug resistant (MDR) phenotypes, including extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) and Acinetobacter baumannii isolated from horses admitted to horse clinics, pose a risk for animal patients and personnel in horse clinics. To estimate current rates of colonization, a total of 341 equine patients were screened for carriage of zoonotic indicator pathogens at hospital admission. Horses showing clinical signs associated with colic (n = 233) or open wounds (n = 108) were selected for microbiological examination of nostril swabs, faecal samples and wound swabs taken from the open wound group. The results showed alarming carriage rates of Gram-negative MDR pathogens in equine patients: 10.7% (34 of 318) of validated faecal specimens were positive for ESBL-E (94%: ESBL-producing Escherichia coli), with recorded rates of 10.5% for the colic and 11% for the open wound group. 92.7% of the ESBL-producing E. coli were phenotypically resistant to three or more classes of antimicrobials. A. baumannii was rarely detected (0.9%), and all faecal samples investigated were negative for Salmonella, both directly and after two enrichment steps. Screening results for the equine nostril swabs showed detection rates for ESBL-E of 3.4% among colic patients and 0.9% in the open wound group, with an average rate of 2.6% (9/340) for both indications. For all 41 ESBL-producing E. coli isolated, a broad heterogeneity was revealed using pulsed-field gel electrophoresis (PFGE) patterns and whole genome sequencing (WGS) -analysis. However, a predominance of sequence type complex (STC)10 and STC1250 was observed, including several novel STs. The most common genes associated with ESBL-production were identified as blaCTX-M-1 (31/41; 75.6%) and blaSHV-12 (24.4%). The results of this study reveal a disturbingly large fraction of multi-drug resistant and ESBL-producing E. coli among equine patients, posing a clear threat to established hygiene management systems and work-place safety of veterinary staff in horse clinics.

description: We present a new formulation of the correlated electron-ion dynamics (CEID) scheme, which systematically improves Ehrenfest dynamics by including quantum fluctuations around the mean-field atomic trajectories. We show that the method can simulate models of non-adiabatic electronic transitions, and test it against exact integration of the time-dependent Schroedinger equation. Unlike previous formulations of CEID, the accuracy of this scheme depends on a single tunable parameter which sets the level of atomic fluctuations included. The convergence to the exact dynamics by increasing the tunable parameter is demonstrated for a model two level system. This algorithm provides a smooth description of the non-adiabatic electronic transitions which satisfies the kinematic constraints (energy and momentum conservation) and preserves quantum coherence. The applicability of this algorithm to more complex atomic systems is discussed.

description: We investigate spin transport in 2-dimensional insulators, with the long-term goal of establishing whether any of the transport coefficients corresponds to the Fu-Kane-Mele index which characterizes 2d time-reversal-symmetric topological insulators. Inspired by the Kubo theory of charge transport, and by using a proper definition of the spin current operator, we define the Kubo-like spin conductance $G_K^{s_z}$ and spin conductivity $σ_K^{s_z}$. We prove that for any gapped, periodic, near-sighted discrete Hamiltonian, the above quantities are mathematically well-defined and the equality $G_K^{s_z} = σ_K^{s_z}$ holds true. Moreover, we argue that the physically relevant condition to obtain the equality above is the vanishing of the mesoscopic average of the spin-torque response, which holds true under our hypotheses on the Hamiltonian operator. This vanishing condition might be relevant in view of further extensions of the result, e.g. to ergodic random discrete Hamiltonians or to Schrödinger operators on the continuum. A central role in the proof is played by the trace per unit volume and by two generalizations of the trace, the principal value trace and it directional version.

description: The non-linear coupled Gross-Pitaevskii equation governing the dynamics of the two component Bose-Einstein condensate (TBEC) is shown to admit pure sinusoidal, propagating wave solutions in quasi one dimensional geometry. These solutions, which exist for a wide parameter range, are then investigated in the presence of a harmonic oscillator trap with time dependent scattering length. This illustrates the procedure for coherent control of these modes through temporal modulation of the parameters, like scattering length and oscillator frequency. We subsequently analyzed this system in an optical lattice, where the occurrence of an irreversible phase transition from superfluid to insulator phase is seen.

description: Tick-borne diseases (TBDs) cause significant losses among livestock and impact the livelihoods of resource-poor farming communities worldwide. In Ethiopia, detailed studies on the epidemiology of tick-borne pathogens (TBPs) in cattle using sensitive molecular detection methods are scarce. The objective of this study was to determine the prevalence and species composition of bovine TBPs of veterinary significance in local cattle populations. A comprehensive cross- sectional epidemiological study was conducted in cattle populations of Illubabor zone in Southwestern Ethiopia from June to August 2013. For this purpose, blood samples were collected from 392 cattle. A combination of polymerase chain reaction (PCR) and a Reverse Line Blot (RLB) hybridization assay was employed for the detection of TBPs in these samples. The PCR/RLB results of the 392 blood samples indicated a high overall prevalence of 96.9% for TBPs, including Theileria mutans (66.1%), Theileria orientalis (51.8%), Anaplasma sp. Omatjenne (25.5%), Anaplasma marginale (14.5%), Babesia bigemina (14.0%) and Theileria velifera (13.0%) and minor occurrences of Ehrlichia ruminantium (0.5%) and Ehrlichia minasensis (0.26%). Moreover, three novel Anaplasma genotypes were detected in bovine blood samples. A phylogenetic analysis revealed that they most likely represent three, but at least two, new species. The prevalence of the three novel Anaplasma species, preliminary designated as Anaplasma sp. Hadesa, Anaplasma sp. Saso and Anaplasma sp. Dedessa, was 12.5%, 14.3% and 5.6%, respectively. Overall, a total of 227 cattle (57.9%) were found to be co-infected with two or more TBPs simultaneously and 86 different species combinations were observed. The findings show a very high burden of infection of cattle with TBPs in Ethiopia. The high frequency of co-infections suggests that clinical manifestations might be complex. Further research is required to determine the pathogenicity, host cell types and vector of the three novel Anaplasma species identified in this study.

description: Exploratory analysis over network data is often limited by the ability to efficiently calculate graph statistics, which can provide a model-free understanding of the macroscopic properties of a network. We introduce a framework for estimating the graphlet count---the number of occurrences of a small subgraph motif (e.g. a wedge or a triangle) in the network. For massive graphs, where accessing the whole graph is not possible, the only viable algorithms are those that make a limited number of vertex neighborhood queries. We introduce a Monte Carlo sampling technique for graphlet counts, called {\em Lifting}, which can simultaneously sample all graphlets of size up to $k$ vertices for arbitrary $k$. This is the first graphlet sampling method that can provably sample every graphlet with positive probability and can sample graphlets of arbitrary size $k$. We outline variants of lifted graphlet counts, including the ordered, unordered, and shotgun estimators, random walk starts, and parallel vertex starts. We prove that our graphlet count updates are unbiased for the true graphlet count and have a controlled variance for all graphlets. We compare the experimental performance of lifted graphlet counts to the state-of-the art graphlet sampling procedures: Waddling and the pairwise subgraph random walk.

description: Colombia, en el marco de los compromisos de carácter internacional frente al incremento en el uso de energías más limpias y la reducción de emisiones, plantea como alternativa la implementación de comunidades energéticas como estructura encaminada a la obtención del servicio público energía eléctrica y la satisfacción de necesidades básicas de grupos de personas. El Gobierno actual le ha apostado a la figura para la prestación eficiente del servicio a un menor costo, la descongestión de las redes, la intervención de menos agentes en la cadena y, en últimas, la descentralización de la prestación de servicios públicos. Al ser una figura nueva en el ordenamiento jurídico es posible que la regulación actual pueda contener barreras no identificadas hasta el momento que podrían desincentivar la estructuración de comunidades energéticas en el país, especialmente en un sector altamente regulado como es el sector de energía eléctrica. Por lo anterior, este trabajo tiene como objetivo principal identificar si la regulación que será aplicada a las comunidades energéticas que buscan ser implementadas en Colombia es óptima y permite la masificación de las comunidades en el país; o en caso contrario, si se encuentran barreras regulatorias que podrían significar un obstáculo para conseguir dichos objetivos.
description: Colombia, within the framework of international commitments to increase the use of cleaner energy and reduce emissions, proposes as an alternative the implementation of energy communities as a structure aimed at obtaining the public electricity service and satisfying the basic needs of groups of people. The current government is committed to the efficient provision of the service at a lower cost, the relieve of the energy networks, the intervention of fewer agents in the chain and, ultimately, the decentralization of the provision of public services. As it is a new figure in the legal system, it is possible that the current regulation may contain barriers that have not been identified so far that could discourage the structuring of energy communities in the country, especially in a highly regulated sector such as the electricity sector. Therefore, the main objective of this paper is to identify whether the regulation that will be applied to the energy communities that seek to be implemented in Colombia is optimal and allows the massification of the communities in the country; or if not, whether there are regulatory barriers that could be an obstacle to achieve these objectives.

description: The discovery of the enhancement of Raman scattering by molecules adsorbed on nanostructured metal surfaces is a landmark in the history of spectroscopic and analytical techniques. Significant experimental and theoretical effort has been directed toward understanding the surface-enhanced Raman scattering (SERS) effect and demonstrating its potential in various types of ultrasensitive sensing applications in a wide variety of fields. In the 45 years since its discovery, SERS has blossomed into a rich area of research and technology, but additional efforts are still needed before it can be routinely used analytically and in commercial products. In this Review, prominent authors from around the world joined together to summarize the state of the art in understanding and using SERS and to predict what can be expected in the near future in terms of research, applications, and technological development. This Review is dedicated to SERS pioneer and our coauthor, the late Prof. Richard Van Duyne, whom we lost during the preparation of this article.
