description: Enabling mobile robots for solving challenging and diverse shape, texture, and motion related tasks with high fidelity vision requires the integration of novel multimodal imaging sensors and advanced fusion techniques. However, it is associated with high cost, power, hardware modification, and computing requirements which limit its scalability. In this paper, we propose a novel Simultaneously Learned Auto Encoder Domain Adaptation (SAEDA)-based transfer learning technique to empower noisy sensing with advanced sensor suite capabilities. In this regard, SAEDA trains both source and target auto-encoders together on a single graph to obtain the domain invariant feature space between the source and target domains on simultaneously collected data. Then, it uses the domain invariant feature space to transfer knowledge between different signal modalities. The evaluation has been done on two collected datasets (LiDAR and Radar) and one existing dataset (LiDAR, Radar and Video) which provides a significant improvement in quadruped robot-based classification (home floor and human activity recognition) and regression (surface roughness estimation) problems. We also integrate our sensor suite and SAEDA framework on two real-time systems (vacuum cleaning and Mini-Cheetah quadruped robots) for studying the feasibility and usability.

description: The aim of the present thesis is to give an overall picture of the Cypriot Enosis movement that developed in Athens in the 1930s. After it sketches out the impact that Cyprus revolt of 1931 had on Greece, the paper examines in detail the policy of the Greek governments in Cyprus question in its various aspects and particularly in the issue of Cypriots exiles of 1931, the British policy towards Athens and the Greek consulate in Cyprus, as well as the reactions for any pro-Enosis movement on the Greek territory. At the same time, it presents unknown aspects of the action and presence of Cypriots in Athens, and particularly their organizations, as well as the Greek support to the Cypriot struggle, as expressed mainly through the Central Committee for Cyprus and Athens Press. Furthermore, it displays the few voices that were heard during the period under review in favour of an alternative line in the issue, that of autonomy, as an interim stage towards the ultimate goal of Enosis.
On the Polyphase Decomposition for Design of Generalized Comb Decimation Filters

description: Generalized comb filters (GCFs) are efficient anti-aliasing decimation filters with improved selectivity and quantization noise (QN) rejection performance around the so called folding bands with respect to classical comb filters. In this paper, we address the design of GCF filters by proposing an efficient partial polyphase architecture with the aim to reduce the data rate as much as possible after the Sigma-Delta A/D conversion. We propose a mathematical framework in order to completely characterize the dependence of the frequency response of GCFs on the quantization of the multipliers embedded in the proposed filter architecture. This analysis paves the way to the design of multiplier-less decimation architectures. We also derive the impulse response of a sample 3rd order GCF filter used as a reference scheme throughout the paper.

description: We consider a social system of interacting heterogeneous agents with learning abilities, a model close to Random Field Ising Models, where the random field corresponds to the idiosyncratic willingness to pay. Given a fixed price, agents decide repeatedly whether to buy or not a unit of a good, so as to maximize their expected utilities. We show that the equilibrium reached by the system depends on the nature of the information agents use to estimate their expected utilities.

Head nurses' perceptions of their roles
Creators: name: Baxter, Elaine Marilyn
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to explore head nurses' perceptions of their roles. The head nurse is in a crucial position of management in a nursing department, acting as a link between upper management and the work group. It is the head nurse who sets the standards and directions for nursing practice on a nursing unit and who manages the staff delivering care. Owing to the decentralization of managerial decisions in many nursing organizations and the change from functional to primary nursing in the care delivery systems, the head nurse's role has changed considerably. Despite this, research into the work of head nurses has been limited and based largely on the perception of others such as staff nurses and directors of nursing. An exploratory, descriptive research design was used to collect and to analyze data. Data collection was based on semi-structured interviews using Mintzberg's framework of ten managerial roles. The procedure of content analysis was used to analyze the data. The findings showed that the head nurses were able to describe their work within the context of each of the 10 managerial roles described by Mintzberg. Roles which were more familiar to them were those of monitor, disseminator, entrepreneur, disturbance handler, resource allocator, leader, and liaison. Roles that were less familiar were those of spokesman, negotiator, and figurehead. Mintzberg's framework was useful as a basis for describing the head nurse position and identifying areas of future development for head nurses. Several general themes were identified from the findings of the study. First, many of the activities of the head nurse in the manager position are unstructured and informal but nonetheless effective. Second, there is a variation in emphasis among roles depending upon the skill of the manager and the situational requirements. Third, the ability of the head nurse to see the whole organization from a systems perspective may require development in future. Finally, head nurses favour a highly participative management perspective, encouraging staff involvement in many ways. The two roles that were particularly significant for head nurses were those of leader and resource allocator. The leader role enabled the head nurse to set directions for the nursing" unit and create an environment in which staff were motivated. The resource allocator role was one which focussed the head nurses' attention on the staff, equipment, and supplies available to the nursing unit. The importance of the resource allocator role may have increased over the past few years, since scarce financial resources have become the boundary for many decisions on nursing units. The knowledge about the behaviours described by the subjects in this study may provide information to improve the educational preparation necessary for the head nurse position. As well, increased understanding about the managerial roles should enable head nurses to facilitate the provision of high quality patient care.

description: As computational infrastructure extends to the edge, it will increasingly offer the same fine-grained resource provisioning mechanisms used in large-scale cloud datacenters, and advances in low-latency, wireless networking technology will allow service providers to blur the distinction between local and remote resources for commodity computing. From the users' perspectives, their devices will no longer have fixed computational power, but rather will appear to have flexible computational capabilities that vary subject to the shared, disaggregated edge resources available in their physical proximity. System software will transparently leverage these ephemeral resources to provide a better end-user experience. We discuss key systems challenges to enabling such tightly-coupled, disaggregated, and ephemeral infrastructure provisioning, advocate for more research in the area, and outline possible paths forward.

description: A lattice Boltzmann model is considered in which the speed of sound can be varied independently of the other parameters. The range over which the speed of sound can be varied is investigated and good agreement is found between simulations and theory. The onset of nonlinear effects due to variations in the speed of sound is also investigated and good agreement is again found with theory. It is also shown that the fluid viscosity is not altered by changing the speed of sound.

Effect of parental presence on the behaviour of the postoperative preschool age child in the pediatric recovery room
Creators: name: Brunke, Margaret Laurel
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the effect of parental presence on the behaviour of the postoperative preschool age child in the pediatric recovery room. The immediate postoperative period has been identified as one of the three most stressful periods in a child's hospitalization. Although it has been suggested that parental presence during painful and stressful procedures can reduce anxiety and influence pain perception, review of the literature demonstrated a scarcity of research that describes the effects of parental presence on children's behaviour in areas such as the recovery room. This study therefore contributes to a currently inadequate research base, and thereby enhances the ability of health care professionals to make objective decisions regarding parental presence in the pediatric recovery room. A quasi-experimental design was used to study two groups of ten children between the ages of three and six years immediately following strabismus repair. The behaviour of ten children accompanied by parents and ten children unaccompanied by parents in the Recovery Room was recorded on videotape which was then analyzed for duration and frequency of 26 items on a behavioural checklist. Differences in duration and frequency of behaviours between the two groups were determined using Kruskal-Wallis one-way analysis of variance and other descriptive analyses. Findings demonstrated that although children in the two groups displayed the same behaviours, the duration and frequency of certain behaviors varied significantly between groups. Children in the parent-present group made more attempts to cope with the pain experience by crying and complaining with the apparent expectation that their parents would comfort them, whereas children in the parent-absent group made more attempts to cope with the pain experience by trying to reduce the pain themselves through rubbing their eyes and protective behaviour. Thus, it was concluded that the parent1s presence in the pediatric recovery room provides the child with an important additional way of coping effectively with the experience, including pain. Implications for nursing practice and nursing research are described in view of the research findings and recommendations are made regarding the process of implementing parental visiting in pediatric recovery rooms.

description: The process of annealing of a CdTe:Cl ingot during its cooling after growth was studied. The annealing was performed in two stages: a high-temperature stage, with an approximate equality of chlorine and cadmium vacancy concentrations established at the thermodynamic equilibrium between the crystal and vapors of volatile components, and a low-temperature stage, with charged defects interacting to form neutral associations. The chlorine concentrations necessary to obtain semi-insulating crystals were determined for various ingot cooling rates in the high temperature stage. The dependence of the chlorine concentration [Cl+Te] in the ingot on the temperature of annealing in the high-temperature stage was found. The carrier lifetimes and drift mobilities were obtained in relation to the temperature and cadmium vapor pressure in the postgrowth annealing of the ingot.

description: We present an inverse scattering approach to defects in classical integrable field theories. Integrability is proved systematically by constructing the generating function of the infinite set of modified integrals of motion. The contribution of the defect to all orders is explicitely identified in terms of a defect matrix. The underlying geometric picture is that those defects correspond to Backlund transformations localized at a given point. A classification of defect matrices as well as the corresponding defect conditions is performed. The method is applied to a collection of well-known integrable models and previous results are recovered (and extended) directly as special cases. Finally, a brief discussion of the classical $r$-matrix approach in this context shows the relation to inhomogeneous lattice models and the need to resort to lattice regularizations of integrable field theories with defects.

description: We study the chiral separation effect (CSE) in two-color and two-flavor QCD (QC$_2$D) to delineate quasiparticle pictures in dense matter from low to high temperatures. Both massless and massive quarks are discussed. We particularly focus on the high density domain where diquarks form a color singlet condensate with the electric charge $1/3$. The condensate breaks baryon number and $U(1)_A$ axial symmetry, and induces the electromagnetic Meissner effects. Within a quark quasiparticle picture, we compute the chiral separation conductivity at one-loop. We have checked that Nambu-Goldstone modes, which should appear in the improved vertices as required by the Ward-Takahashi identities, do not contribute to the chiral separation conductivity due to their longitudinal natures. In the static limit, the destructive interferences in the particle-hole channel, as in usual Meissner effects, suppress the conductivity (in chiral limit, to $1/3$ of the normal phase's). This locally breaks the universality of the CSE coefficients, provided quasiparticle pictures are valid in the bulk matter.

description: Most particle induced X-ray emission (PIXE) data analysis codes are not focused on handling multilayered samples. We have developed an open-source library called "LibCPIXE", for PIXE data analysis. It is written in standard C and implements functions for simulating X-ray yields of PIXE spectra taken from arbitrary samples, including multilayered targets. The library is designed to be fast, portable, modular and scalable, as well as to facilitate its incorporation into any existing program. In order to demonstrate the capabilities of the library, a program called CPIXE was developed and used to analyze various real samples involving both bulk and layered samples. Just as the library, the CPIXE source code is freely available under the General Public License. We demonstrate that it runs both under GNU/Linux systems as well as under MS Windows. There is in principle no limitation to port it to other platforms.

description: A framework for integrating transfer matrices with particle-in-cell simulations is developed for TeV staging of plasma wakefield accelerators. Using nonlinear transfer matrices in terms up to ninth order in normalized energy spread $\sqrt{\langleδγ^2\rangle}$ and deriving a compact expression for the chromatic emittance growth in terms of the nonlinear matrix, plasma wakefield accelerating stages simulated using the three-dimensional particle-in-cell framework OSIRIS 4.0 were combined to model acceleration of an electron beam from 10 GeV to 1 TeV in 85 plasma stages of meter scale-length with long density ramps and connected by simple focusing lenses. In this calculation, we find that for initial relative energy spreads below $10^{-3}$, energy-spread growth below $10^{-5}$ of the energy gain per stage and normalized emittance below mm-mrad, the chromatic emittance growth can be minimal. The technique developed here may be useful for plasma collider design, and potentially could be expanded to encompass non-linear wake structures and include other degrees of freedom such as lepton spin.

description: Here, we demonstrate the selective cellobiose (building block of cellulose) photoreforming for gluconic acid and syngas co-production in acidic conditions by rationally designing a bifunctional polymeric carbon nitride (CN) with potassium/sulfur co-dopant. This heteroatomic doped CN photocatalyst possesses enhanced visible light absorption, higher charge separation efficiency than pristine CN. Under acidic conditions, cellobiose is not only more efficiently hydrolyzed into glucose but also promotes the syngas and gluconic acid production. Density functional theory (DFT) calculations reveal the favorable generation of •O2− during the photocatalytic reaction, which is essential for gluconic acid production. Consequently, the fine-designed photocatalyst presents excellent cellobiose conversion (>80%) and gluconic acid selectivity (>70%) together with the co-production of syngas (~56 μmol g-1 h-1) under light illumination. The current work demonstrates the feasibility of biomass photoreforming with value-added chemicals and syngas co-production under mild condition.

description: Online Social Networks (OSNs) have become an integral part of today's Web. Politicians, celebrities, revolutionists, and others use OSNs as a podium to deliver their message to millions of active web users. Unfortunately, in the wrong hands, OSNs can be used to run astroturf campaigns to spread misinformation and propaganda. Such campaigns usually start off by infiltrating a targeted OSN on a large scale. In this research, we evaluate how vulnerable OSNs are to a large-scale infiltration by socialbots: computer programs that control OSN accounts and mimic real users. We adopt a traditional web-based botnet design and built a Socialbot Network (SbN): a group of adaptive socialbots that are orchestrated in a command-and-control fashion. We operated such an SbN on Facebook—a 750 million user OSN—for about 8 weeks. We collected data related to users' behavior in response to a large-scale infiltration where socialbots were used to connect to a large number of Facebook users. Our results show that (1) OSNs, such as Facebook, can be infiltrated with a success rate of up to 80%, (2) depending on users' privacy settings, a successful infiltration can result in privacy breaches where even more users' data are exposed when compared to a purely public access, and (3) in practice, OSN security defenses, such as the Facebook Immune System, are not effective enough in detecting or stopping a large-scale infiltration as it occurs.

description: The research in anomaly detection lacks a unified definition of what represents an anomalous instance. Discrepancies in the nature itself of an anomaly lead to multiple paradigms of algorithms design and experimentation. Predictive maintenance is a special case, where the anomaly represents a failure that must be prevented. Related time-series research as outlier and novelty detection or time-series classification does not apply to the concept of an anomaly in this field, because they are not single points which have not been seen previously and may not be precisely annotated. Moreover, due to the lack of annotated anomalous data, many benchmarks are adapted from supervised scenarios. To address these issues, we generalise the concept of positive and negative instances to intervals to be able to evaluate unsupervised anomaly detection algorithms. We also preserve the imbalance scheme for evaluation through the proposal of the Preceding Window ROC, a generalisation for the calculation of ROC curves for time-series scenarios. We also adapt the mechanism from a established time-series anomaly detection benchmark to the proposed generalisations to reward early detection. Therefore, the proposal represents a flexible evaluation framework for the different scenarios. To show the usefulness of this definition, we include a case study of Big Data algorithms with a real-world time-series problem provided by the company ArcelorMittal, and compare the proposal with an evaluation method.

We present the exact solution for the case of an infinite wire and show that in this case the dc current vanishes identically. We also investigate a confined system consistent in an annular arrangement coupled to a particle reservoir. We present a perturbative treatment that allows for the analytical expressions of the dc current in the lowest order of the amplitudes of the potential. We also present results obtained from the exact numerical solution of the problem.

description: Collective behavior of pulse-coupled oscillators has been investigated widely. As an example of pulse-coupled networks, fireflies display many kinds of flashing patterns. Mirollo and Strogatz (1990) proposed a pulse-coupled oscillator model to explain the synchronization of South East Asian fireflies ({\itshape Pteroptyx malaccae}). However, transmission delays were not considered in their model. In fact, the presence of transmission delays can lead to desychronization. In this paper, pulse-coupled oscillator networks with delayed excitatory coupling are studied. Our main result is that under reasonable assumptions, pulse-coupled oscillator networks with delayed excitatory coupling can not achieve complete synchronization, which can explain why another species of fireflies ({\itshape Photinus pyralis}) rarely synchronizes flashing. Finally, two numerical simulations are given. In the first simulation, we illustrate that even if all the initial phases are very close to each other, there could still be big variations in the times to process the pulses in the pipeline. It implies that asymptotical synchronization typically also cannot be achieved. In the second simulation, we exhibit a phenomenon of clustering synchronization.

description: Diamond Open Access Standard (DOAS) sets out guidelines for Diamond publishing. It helps scholarly publishers ensure quality and transparency in journal publishing processes.

The original version of DOAS is intended for Diamond open access (OA) publishers and service providers. However, improvements in individual journals are usually made by editorial bodies. To ensure wide uptake, this guide translates the DOAS requirements to the context of individual journals, making it easier for editorial bodies to align their journals with the DOAS requirements. 

It complements existing guides and checklists for enhancing journal quality and can also help journals in preparing for indexing in the Directory of Open Access Journals (DOAJ).

description: The performance of variational quantum algorithms relies on the success of using quantum and classical computing resources in tandem. Here, we study how these quantum and classical components interrelate. In particular, we focus on algorithms for solving the combinatorial optimization problem MaxCut, and study how the structure of the classical optimization landscape relates to the quantum circuit used to evaluate the MaxCut objective function. In order to analytically characterize the impact of quantum features on the critical points of the landscape, we consider a family of quantum circuit ansätze composed of mutually commuting elements. We identify multiqubit operations as a key resource and show that overparameterization allows for obtaining favorable landscapes. Namely, we prove that an ansatz from this family containing exponentially many variational parameters yields a landscape free of local optima for generic graphs. However, we further prove that these ansätze do not offer superpolynomial advantages over purely classical MaxCut algorithms. We then present a series of numerical experiments illustrating that noncommutativity and entanglement are important features for improving algorithm performance.

description: In the paper, we describe the Drinfel'd double structure of the $n$-rank Taft algebra and all of its simple modules, and then endow its $R$-matrices with some application to knot invariants. The knot invariants we get is a generalization of the Jones polynomial, in particular, it recovers the Jones polynomial in rank $1$ case, while in rank $2$ case, it is the one-parameter specialization of the two-parameter unframed Dubrovnik polynomial, and in higher rank case it is the composite ($n$-power) of the Jones polynomial.

description: We report the detection of correlated anisotropies in the Cosmic Far-Infrared Background at 160 microns. We measure the power spectrum in the Spitzer/SWIRE Lockman Hole field. It reveals unambiguously a strong excess above cirrus and Poisson contributions, at spatial scales between 5 and 30 arcminutes, interpreted as the signature of infrared galaxy clustering. Using our model of infrared galaxy evolution we derive a linear bias b=1.74 \pm 0.16. It is a factor 2 higher than the bias measured for the local IRAS galaxies. Our model indicates that galaxies dominating the 160 microns correlated anisotropies are at z~1. This implies that infrared galaxies at high redshifts are biased tracers of mass, unlike in the local Universe.

Intolerance of uncertainty and reinstatement

description: The return of fear model of reinstatement is an understudied phenomenon that may shed some light on the mechanisms of clinical relapse seen in anxiety disorders. Previous studies have found altered threat responding during reinstatement phases of classical threat conditioning tasks connected to Intolerance of uncertainty (IU), an emerging transdiagnostic feature seen in various clinical disorders. This study recruited 69 participants (33 females, 33 males, and 3 non-binaries) aged between 18 and 55 years to explore the possible impact that IU, and other measures of individual difference, may have on reinstatement effects using an online classical conditioning task. Participants completed questionnaires on IU, distress tolerance (DT), neuroticism, and depression, anxiety, and stress, followed by a threat conditioning task which utilised the face of a fearful woman, paired with a fearful female scream as the unconditioned stimulus (US). None of the measures of individual difference moderated the relationship between extinction learning and reinstatement, however DT total, absorption, and regulation significantly predicted reinstatement. The task successfully facilitated differential threat conditioning and reinstatement which supports the feasibility of online associative learning tasks. Results from this study could help to gain further understanding of reinstatement, and therefore further the understanding of clinical relapse.

Για τον σκοπό αυτό πραγματοποιήσαμε συνολικά τρία πειράματα πεπτικότητας και ένα πείραμα αποδομησιμότητας με ευνουχισμένους κριούς της φυλής Χίου. Παρουσιάσαμε τις υπάρχουσες πληροφορίες, αλλά και τις ελλείψεις που υπήρχαν σχετικά με το θέμα. Κατόπιν, δημιουργήσαμε πίνακες με τη χημική σύσταση των πρωτεϊνικών πηγών και των σιτηρεσίων. Στη συνέχεια παρουσιάσαμε, με πίνακες και διαγράμματα, τους συντελεστές της φαινομένης πεπτικότητας των θρεπτικών συστατικών τόσο των ίδιων των τροφών, όσο και των σιτηρεσίων, καθώς και τις παραμέτρους της αποδομησιμότητας των τροφών. Ένα άλλο θέμα που μελετήσαμε ήταν ο ισολογισμός αζώτου των σιτηρεσίων. Τέλος, βρήκαμε τις τροφές που θα μπορούσαν να αντικαταστήσουν το σογιάλευρο στα σιτηρέσια των προβάτων.
description: The aim of the present thesis was the measurement of degradability and apparent digestibility of nutritious components and energy of sunflower meal, rapeseed meal, lupin seed, faba bean seed, vetch seed, pea seed, flaxseed and chickpea seed, compared to soybean meal, in order to estimate the ability of these protein sources to replace completely soybean meal in sheep rations and to provide important information that could make this replacement possible. For this aim we conducted three digestibility trials and one degradability trial with castrated Chios rams. We presented the existing information, but also the lacks that existed with regard to the subject. Then, we created tables with the chemical composition of the protein sources and the rations. Afterwards we presented, with tables and diagrams, the apparent digestibility coefficients of nutritious components of feeds and rations and the degradability parameters of the feeds. Another subject that we measured was the nitrogen balance of the rations. Finally, we found the foods which could replace soybean meal in sheep rations.
