description: Automotive radar is a key component in an ADAS. The increasing number of radars implemented in vehicles makes interference between them a noteworthy issue. One method of interference mitigation is to limit the TBP of radar waveforms. However, the problems of how much TBP is necessary and how to optimally utilize the limited TBP have not been addressed. We take CWS as an example and propose a method of designing the radar waveform parameters oriented by the performance of CWS We propose a metric to quantify the CWS performance and study how the radar waveform parameters (bandwidth and duration) influence this metric. Then, the waveform parameters are designed with a limit on the TBP to optimize the system performance. Numerical results show that the proposed design outperforms the state-of-the-art parameter settings in terms of system performance and resource or energy efficiency.

description: We study screening properties of the two-dimensional electron gas with Rashba spin-orbit coupling. Calculating the dielectric function within the random phase approximation, we describe the new features of screening induced by spin-orbit coupling, which are the extension of the region of particle-hole excitations and the spin-orbit-induced suppression of collective modes. The required polarization operator is calculated in an analytic form without any approximations. Carefully deriving its static limit, we prove the absence of a small-$q$ anomaly at zero frequency. On the basis of our results at finite frequencies we establish the new boundaries of the particle-hole continuum and calculate the SO-induced lifetime of collective modes such as plasmons and longitudinal optical phonons. According to our estimates, these effects can be resolved in inelastic Raman scattering. We evaluate the experimentally measurable dynamic structure factor and establish the range of parameters where the described phenomena are mostly pronounced.

Effects of adjuvanted AEROMONAS SALMONICIDA vaccines on growth, oxygen consumption, and selected haematological and immunological variables in juvenile rainbow trout (ONCORHYNCHUS MYKISS)
Creators: name: Ackerman, Paige A.
Publisher: name: University of British Columbia

description: Seven injectible vaccines against Aeromonas salmonicida were tested to determine the various effects they might have on selected variables of the physiology, swimming performance and immune functions of juvenile rainbow trout (Oncorhynchus mykiss). The study involved three trials of consecutively longer times, 5, 12, and 24 weeks in duration, at the beginning of which fish were injected with a variety of adjuvanted and non-adjuvanted vaccines. The array of vaccine preparations was based on a simple, formalin killed, Aeromonas salmonicida bacterin. They were: bacterin only, bacterin adjuvanted with levamisole, bacterin in oil emulsion, microencapsulated- bacterin, microencapsulated bacterin with the addition of muramyl dipeptide, microencapsulated bacterin with P-1,3 glucan added, and microencapsulated bacterin with the addition of Vibrio anguillarum lipopolysaccharide (LPS). Midway through each of the three trials, oxygen consumption was determined in whole fish as an indicator of metabolic rate. At the termination of each study, fish weights and lengths were determined and specific growth rates were calculated. Fish were sacrificed and blood was collected for determination of haematocrit, leucocrit, differential white blood cell count, agglutinating antibody titre, and haemolytic activity in the plasma. Somatic organs were dissected from the animals, and the somatic indices for total kidney, head kidney and spleen were determined. Finally, kidney lysozyme activity was determined from tissue homogenates. The highest level and broadest range of positive responses were gained from the A. salmonicida bacterin which was microencapsulated with V. anguillarum LPS as an immunostimulant. This preparation proved to increase the metabolic and specific growth rates of fish over a short period of time. Such effects may have potential long term positive impacts on the size of fish at harvest. The LPS treatment also caused a high plasma antibody titre, and high levels of kidney lysozyme activity for a substantially longer period of time than other immunizations.

description: Erroneous— Psychroplanes obsoleta (Hérouard, 1899)   Reports for the Azores:
 Peniagone (Kolga) obsoleta (Hérouard, 1899) — Perrier 1902: 276.
 Type locality: between the Azores and the European continent (39°50’N, 17°57’45”W).
 See: Hérouard (1899: 170, fig. 1; 1902: 41–42, pl. 6, figs. 11–15, pl. 8, figs. 16–18, as Kolga obsoleta); Hansen (1975: 134–135, fig. 56).
 Occurrence: known from the Mid-Atlantic near the equator and the deep waters between the Azores and the European shores (Hansen 1975); reported elsewhere in the east of the Japanese Trench (Pacific; Gebruk et al. 2014).
 Depth: 4,275–6,096 m (Gebruk et al. 2014).
 Habitat: soft sediments (Hérouard 1923).
 Remarks: Perrier (1902) mentioned Psychroplanes obsoleta among the species reported by Hérouard from the Azores. However, Hérouard (1902) clearly states that the specimens came from waters between the Azores and the European mainland (Princesse Alice, sta 753: 39°50’00”N, 17°57’45”W, 4,360 m). It is possible that P. obsoleta may occur in the abyssal waters of the Azores, considering the known geographical and bathymetric distribution of this species, but at present no records from the archipelago exist.

description: The classical alternating minimization (or projection) algorithm has been successful in the context of solving optimization problems over two variables. The iterative nature and simplicity of the algorithm has led to its application to many areas such as signal processing, information theory, control, and finance. A general set of sufficient conditions for the convergence and correctness of the algorithm is quite well-known when the underlying problem parameters are fixed. In many practical situations, however, the underlying problem parameters are changing over time, and the use of an adaptive algorithm is more appropriate. In this paper, we study such an adaptive version of the alternating minimization algorithm. As a main result of this paper, we provide a general set of sufficient conditions for the convergence and correctness of the adaptive algorithm. Perhaps surprisingly, these conditions seem to be the minimal ones one would expect in such an adaptive setting. We present applications of our results to adaptive decomposition of mixtures, adaptive log-optimal portfolio selection, and adaptive filter design.

description: The current situation of COVID-19 demands novel solutions to boost healthcare services and economic growth. A full-fledged solution that can help the government and people retain their normal lifestyle and improve the economy is crucial. By bringing into the picture a unique incentive-based approach, the strain of government and the people can be greatly reduced. By providing incentives for actions such as voluntary testing, isolation, etc., the government can better plan strategies for fighting the situation while people in need can benefit from the incentive offered. This idea of combining strength to battle against the virus can bring out newer possibilities that can give an upper hand in this war. As the unpredictable future develops, sharing and maintaining COVID related data of every user could be the needed trigger to kick start the economy and blockchain paves the way for this solution with decentralization and immutability of data.

QSO pairs {\it across} Active galaxies: Evidence of Blueshifts?
Creators: name: Basu, D.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Several QSO pairs have been reported and their redshifts determined, where the two objects in each pair are located {\it across} an active galaxy. The usually accepted explanation of such occurrences is that the pair is ejected from the active galaxy. Currebtly interpreted redshifted spectra for both the QSOs imply that both the objects are receding from the observer. However, ejection can occur towards and away from the observer with equal probability. We argue that for a system with two QSOs {\it across} the parent galaxy, ejection should have occurred in opposite directions, whereby one object will be approaching us and the other will be receding from us. The former would be exhibiting a blueshifted spectrum. We analyse here a sample of four such pairs and show that the observed spectrum of one QSO in each pair can be interpreted as blueshifted. The other exhibits the ususal redshifted spectrum.A scenario based on the 'sling-shot' mechanism of ejection is presented to explain the ocurrences of the pairs in opposite sides of the active galaxies moving in opposite durections.

description: We consider the nonequilibrium Casimir pressure in the system of two parallel graphene-coated plates one of which is either warmer or cooler than the environment. The electromagnetic response of graphene coating characterized by the nonzero energy gap and chemical potential is described in the framework of the Dirac model by means of the polarization tensor. It is shown that the magnitude of the nonequilibrium Casimir pressure on a warmer plate than the environment is larger and on a cooler plate is smaller than the magnitude of the standard Casimir pressure in the state of thermal equilibrium. According to our results, the spatially local theory underestimates the role of the effects of nonequilibrium. This underestimation increases for asmaller chemical potential of the graphene coating and at lower temperatures of the cooled plate. Possible applications of the obtained results are discussed.

 Occurrence: Western Atlantic, from Brazil, northwards to Bermuda including the Gulf of Mexico and the Caribbean (Deichmann 1954).
 Depth: shallow waters, 1–7 m (Laguarda-Figueras et al. 2001).
 Habitat: among algae, in mangrove swamps and reef lagoons (H.L. Clark 1942).
 Larval stage: viviparous (Deichmann 1954).
 Remarks: Hérouard (1923) tentatively attributed poorly preserved material (mainly muscle fragments, with no calcareous deposits) collected by Princesse Alice in the Azores (sta 1349: 38°35’00”N, 28°05’45”W), at a depth of 1,250 m to the tropical species Synaptula hydriformis. The depth distribution of this species is restricted to the first few meters, which makes the Azorean reported depth highly unlikely.

description: "Incentivized" advertising platforms allow mobile app developers to acquire new users by directly paying users to install and engage with mobile apps (e.g., create an account, make in-app purchases). Incentivized installs are banned by the Apple App Store and discouraged by the Google Play Store because they can manipulate app store metrics (e.g., install counts, appearance in top charts). Yet, many organizations still offer incentivized install services for Android apps. In this paper, we present the first study to understand the ecosystem of incentivized mobile app install campaigns in Android and its broader ramifications through a series of measurements. We identify incentivized install campaigns that require users to install an app and perform in-app tasks targeting manipulation of a wide variety of user engagement metrics (e.g., daily active users, user session lengths) and revenue. Our results suggest that these artificially inflated metrics can be effective in improving app store metrics as well as helping mobile app developers to attract funding from venture capitalists. Our study also indicates lax enforcement of the Google Play Store's existing policies to prevent these behaviors. It further motivates the need for stricter policing of incentivized install campaigns. Our proposed measurements can also be leveraged by the Google Play Store to identify potential policy violations.

description: Spin wave spectra of perpendicularly magnetized disks with trilayers consisting of a 100 nm permalloy (Py) layer sandwiched by two Cu layers of 30 nm, are measured individually with a Magnetic Resonance Force Microscope (MRFM). It is demonstrated by 3D micromagnetic simulations that in disks having sub-micron size diameters, the lowest energy spin wave mode of the saturated state is not spatially uniform but rather is localized at the center of the Py/Cu interface in the region of a minimum demagnetizing field.

description: Lévy walk process is one of the most effective models to describe superdiffusion, which underlies some important movement patterns and has been widely observed in the micro and macro dynamics. From the perspective of random walk theory, here we investigate the dynamics of Lévy walks under the influences of the constant force field and the one combined with harmonic potential. Utilizing Hermite polynomial approximation to deal with the spatiotemporally coupled analysis challenges, some striking features are detected, including non Gaussian stationary distribution, faster diffusion, and still strongly anomalous diffusion, etc.

description: RNAs play crucial and versatile roles in biological processes. Computational prediction approaches can help to understand RNA structures and their stabilizing factors, thus providing information on their functions, and facilitating the design of new RNAs. Machine learning (ML) techniques have made tremendous progress in many fields in the past few years. Although their usage in protein-related fields has a long history, the use of ML methods in predicting RNA tertiary structures is new and rare. Here, we review the recent advances of using ML methods on RNA structure predictions and discuss the advantages and limitation, the difficulties and potentials of these approaches when applied in the field.

description: The present scientific research was designed to study the phenomenon of dyslexia. We presented the international scientific definitions, characteristics and types of dyslexia, its symptoms and causes, as well as additional disorders and difficulties that accompany dyslexia and ways of dealing with particular emphasis on education. Particularly, the primary objective was to investigate the strategies and techniques that can be used during the educational process, especially in foreign language teaching, to enhance the skills of students with dyslexia. Furthermore, we critically examined the findings of current research, past and recent literature reports, both domestic and foreign. Additionally, we mentioned the Multisensory Structured Learning Approach (MSLA) and the techniques that derive through this approach, as it is extensively suggested from the Greek and foreign literature as the most appropriate for language learning students with dyslexia. Finally we listed conclusions and recommendations.

Το δείγμα αποτελείται κυρίως από το άνω προγναθικό και τα άνω γναθικά οστά, ενώ διατηρούνται και κάποια δόντια στη φυσική τους θέση. Το μελετώμενο δείγμα συγκρίθηκε με φωτογραφικό υλικό του ολότυπου του αμφισβητούμενου για την εγκυρότητά του Varanus marathonensis από το Άνω Μειόκαινο του Πικερμίου, δείγματα από απολιθωματοφόρες θέσεις του Μέσου και Άνω Μειοκαίνου της Ισπανίας και αρτίγονα είδη. Η μελέτη του απολιθωμένου υλικού κατέληξε στο συμπέρασμα ότι όλα ανήκουν στο πλέον έγκυρο ευρωπαϊκό είδος Varanus marathonensis, με δύο νέα προτεινόμενα διαγνωστικά χαρακτηριστικά τα οποία είναι: η προς το εσωτερικό επεκτεινόμενη ελασματοειδής επιφάνεια (mefp) στο ραχιαίο τμήμα της προσωπικής απόφυσης και η παρουσία της εγκάρσιας αύλακας (las) στο άνω γναθικό οστό, τα οποία δεν έχουν περιγραφεί ποτέ μέχρι τώρα για κανένα άλλο αρτίγονο και απολιθωμένο είδος.
description: The purpose of the present master thesis is the study of the anterior part of a Varanus skull which was found in the Middle Turolian (around 7.3 Ma) fossiliferous site in the Mitilinii Basin of Samos island (eastern Aegean Sea, Greece). The specimen consists mainly of the premaxilla, maxillae and some teeth in situ. The studied specimen has been compared with the holotype of the extinct species of uncertain validity Varanus marathonensis (Pikermi, Greece), fossil specimens from the Middle and Upper Miocene of Spain and extant species. The study suggests that all the available fossil material belongs to the same, thus valid species Varanus marathonensis with two new diagnostic features: the medial expansion of the facial process and the presence of the lateral sulcus in the maxilla bone, features that have never beεn described for any extant or fossil species.

description: The buckling of elastic bodies is a common phenomenon in the mechanics of solids. Wrinkling of membranes can often be interpreted as buckling under constraints that prohibit large amplitude deformation. We present a combination of analytic calculations, experiments, and simulations to understand wrinkling patterns generated in a bilayer membrane. The model membrane is composed of a flexible spherical shell that is under tension and that is circumscribed by a stiff, essentially incompressible strip with bending modulus B. When the tension is reduced sufficiently to a value σ, the strip forms wrinkles with a uniform wavelength found theoretically and experimentally to be λ= 2π(B/σ)^{1/3}. Defects in this pattern appear for rapid changes in tension. Comparison between experiment and simulation further shows that, with larger reduction of tension, a second generation of wrinkles with longer wavelength appears only when B is sufficiently small.

description: As the time goes by, the quality of software is decreased, causing the cost magnification. This situation affects to the further development and software maintenance. However, through calculating and controlling the quality of a software product throughout its lifetime, the technical debt becomes manageable, reducing cost of ownership. This is the reason why the calculation of software quality of a system attracts the interest, and nowadays there are disagreements in the qualitative assessment. This thesis uses a quality tool for evaluating specific industrial computer system, and translates it in the technical debt term. Moreover, considering the dimension of quality as perceived by the professionals who take part in the development of the industrial system, it calculates the technical debt to this view. The purpose of this study is to determine the percentage of similarity between the quality assessments and technical debt measurements of the same software, which are derived from these two different sources, and what are reasons that contribute to the deviation. Finally, the conclusion of this work presents the divergence of two different approaches to software quality.

description: Strong correlations between leptogenesis and low energy CP violating leptonic processes have been shown by us to exist in the minimal left-right symmetric model with spontaneous CP violation. In this note, we investigate the implications of this model for the electric dipole moment of the electron. With an additional broken U(1)_H symmetry, the seesaw scale can be lowered to close to the electroweak scale. This additional symmetry also makes the connection between CP violation in quark sector to that in the lepton sector possible.

description: The use of ultrasonic guided waves to probe the materials/structures for damage continues to increase in popularity for non-destructive evaluation (NDE) and structural health monitoring (SHM). The use of high-frequency waves such as these offers an advantage over low-frequency methods from their ability to detect damage on a smaller scale. However, in order to assess damage in a structure, and implement any NDE or SHM tool, knowledge of the behaviour of a guided wave throughout the material/structure is important (especially when designing sensor placement for SHM systems). Determining this behaviour is extremely diffcult in complex materials, such as fibre-matrix composites, where unique phenomena such as continuous mode conversion takes place. This paper introduces a novel method for modelling the feature-space of guided waves in a composite material. This technique is based on a data-driven model, where prior physical knowledge can be used to create structured machine learning tools; where constraints are applied to provide said structure. The method shown makes use of Gaussian processes, a full Bayesian analysis tool, and in this paper it is shown how physical knowledge of the guided waves can be utilised in modelling using an ML tool. This paper shows that through careful consideration when applying machine learning techniques, more robust models can be generated which offer advantages such as extrapolation ability and physical interpretation.

description: In this article, a modification of the rapidly convergent approximation method is proposed to solve a coupled Korteweg-de Vries equations with conformable derivative that govern shallow-water waves. Based on the Leibniz and chain rule of conformable derivative, these equations reduced into ODEs with integer-order using traveling wave transformation. Adopting the modified scheme a new novel exact solution of the reduced coupled ordinary differential equations is obtained in terms of exponential functions. Finally, by putting them back into traveling wave transformation the solutions of the considered partial differential equations with conformable derivative are derived. To ensure the boundedness of the derived solutions few theorems have been proposed and proved. The derived results of the theorems are utilized to plot the solutions. Graphics exhibit that solutions have variant multi-hump soliton peculiarities and their tails decay to zero exponentially in a monotonic manner. These results not only show the efficiency of the modified scheme but also establish that the solution is enriched with new multi-hump features.

description: We use intersection theory techniques to define an invariant of closed 3-manifolds counting the characters of irreducible representations of the fundamental group in PSL(2,C). We note several properties of the invariant and compute the invariant for certain Seifert fibered spaces and for some Dehn surgeries on twist knots. We discuss the relationship between this invariant and the SL(2,C)-invariant.

description: Modern multicore systems are migrating from homogeneous systems to heterogeneous systems with accelerator-based computing in order to overcome the barriers of performance and power walls. In this trend, FPGA-based accelerators are becoming increasingly attractive, due to their excellent flexibility and low design cost. In this paper, we propose the architectural support for efficient interfacing between FPGA-based multi-accelerators and chip-multiprocessors (CMPs) connected through the network-on-chip (NoC). Distributed packet receivers and hierarchical packet senders are designed to maintain scalability and reduce the critical path delay under a heavy task load. A dedicated accelerator chaining mechanism is also proposed to facilitate intra-FPGA data reuse among accelerators to circumvent prohibitive communication overhead between the FPGA and processors. In order to evaluate the proposed architecture, a complete system emulation with programmability support is performed using FPGA prototyping. Experimental results demonstrate that the proposed architecture has high-performance, and is light-weight and scalable in characteristics.

description: Two approaches to renormalization-group improvement are examined: the substitution of the solutions of running couplings, masses and fields into perturbatively computed quantities is compared with the systematic sum of all the leading log (LL), next-to-leading log (NLL) etc. contributions to radiatively corrected processes, with n-loop expressions for the running quantities being responsible for summing N^{n}LL contributions. A detailed comparison of these procedures is made in the context of the effective potential V in the 4-dimensional O(4) massless $λϕ^{4}$ model, showing the distinction between these procedures at two-loop order when considering the NLL contributions to the effective potential V.

description: Query optimizer is at the heart of the database systems. Cost-based optimizer studied in this paper is adopted in almost all current database systems. A cost-based optimizer introduces a plan enumeration algorithm to find a (sub)plan, and then uses a cost model to obtain the cost of that plan, and selects the plan with the lowest cost. In the cost model, cardinality, the number of tuples through an operator, plays a crucial role. Due to the inaccuracy in cardinality estimation, errors in cost model, and the huge plan space, the optimizer cannot find the optimal execution plan for a complex query in a reasonable time. In this paper, we first deeply study the causes behind the limitations above. Next, we review the techniques used to improve the quality of the three key components in the cost-based optimizer, cardinality estimation, cost model, and plan enumeration. We also provide our insights on the future directions for each of the above aspects.

The pain cues of cognitively impaired elderly people: an ethnoscientific study of gerontological nurses’ perspectives
Creators: name: Parke, Belinda Bernice
Publisher: name: University of British Columbia
Year: 2009

description: Many gaps exist in our ability to detect and assess pain in cognitively impaired elderly people. In this study, an ethnoscientific approach was used to access gerontological nurses' knowledge of pain in the cognitively impaired elderly. In keeping with an ethnoscientific approach, judgement sampling, a nonprobability method for selection of knowledgable informants was used to select six gerontological nurse participants. All informants were over the age of thirty and had between six and fifteen years of experience working with cognitively impaired elderly people. Two data collection procedures were used; story telling interviews and retrospective chart reviews. The story telling interviews involved a systematic exploration of gerontological nurses' observations and perceptions caring for cognitively impaired elderly people in pain. Formal elicitation procedures were used as the framework for the interviews. As such, both the questions and the answers were discovered by the nurse informants. The second data source, retrospective chart reviews, focused on the written language other nurses used to describe pain. The chart review was intended to give breadth to the data that was collected in the interviews. Twenty-one charts of cognitively impaired elderly people were reviewed, sixteen were included in the study and five were excluded. A process of constant comparative analysis was used to determine the meanings nurses attached to the words and phrases they used to describe their observations. The findings from this study revealed that nurses use three pain cue groupings, overt behaviour, appearance and sounds. In addition, the findings revealed that the gerontological nurses in this study were able to integrate "knowing the patient" with knowing by intuitive perception. Together, each method of knowing enhanced the nurses ability to infer that pain was a problem for an impaired elder.

description: Solving land-use allocation problems can help us to deal with some of the most urgent global environmental issues. Since these problems are NP-hard, effective optimizers are needed to handle them. The knowledge about variable dependencies allows for proposing such tools. However, in this work, we consider a real-world multi-objective problem for which standard variable dependency discovery techniques are inapplicable. Therefore, using linkage-based variation operators is unreachable. To address this issue, we propose a definition of problem-dedicated variable dependency. On this base, we propose obtaining masks of dependent variables. Using them, we construct three novel crossover operators. The results concerning real-world test cases show that introducing our propositions into two well-known optimizers (NSGA-II, MOEA/D) dedicated to multi-objective optimization significantly improves their effectiveness.

description: Media with engineered magnetization are essential building blocks in superconductivity, magnetism and magnon spintronics. However, the established thin-film and lithographic techniques insufficiently suit the realization of planar components with on-demand-tailored magnetization in the lateral dimension. Here, we demonstrate the engineering of the magnetic properties of CoFe-based nanodisks fabricated by the mask-less technique of focused electron beam induced deposition (FEBID). The material composition in the nanodisks is tuned \emph{in-situ} via the e-beam waiting time in the FEBID process and their post-growth irradiation with Ga ions. The magnetization $M_s$ and exchange stiffness $A$ of the disks are deduced from perpendicular ferromagnetic resonance measurements. The achieved $M_s$ variation in the broad range from $720$ emu/cm$^3$ to $1430$ emu/cm$^3$ continuously bridges the gap between the $M_s$ values of such widely used magnonic materials as permalloy and CoFeB. The presented approach paves a way towards nanoscale 2D and 3D systems with controllable and space-varied magnetic properties.

description: As digitization increases, the need to automate various entities becomes crucial for development. The data generated by the IoT devices need to be processed accurately and in a secure manner. The basis for the success of such a scenario requires blockchain as a means of unalterable data storage to improve the overall security and trust in the system. By providing trust in an automated system, with real-time data updates to all stakeholders, an improved form of implementation takes the stage and can help reduce the stress of adaptability to complete automated systems. This research focuses on a use case with respect to the real time Internet of Things (IoT) network which is deployed at the beach of Chicago Park District. This real time data which is collected from various sensors is then used to design a predictive model using Deep Neural Networks for estimating the battery life of IoT sensors that is deployed at the beach. This proposed model could help the government to plan for placing orders of replaceable batteries before time so that there can be an uninterrupted service. Since this data is sensitive and requires to be secured, the predicted battery life value is stored in blockchain which would be a tamper-proof record of the data.
