description: In this paper, we find all integer sequences of the form a^n + b^n, where a and b are complex numbers and n is a nonnegative integer. We prove that if p and q are integers, then there is a correspondence between the roots of the quadratic equation z^2 - pz - q = 0 and integer sequences of the form a^n + b^n. In addition, we will show that there are no integer sequences of the form a^n - b^n. Finally, we use special values of a and b to obtain a range of formulas involving Lucas and Fibonacci numbers.

Trajectories at risk : examining young children's self-regulation in classroom contexts from kindergarten to grade 5
Creators: name: Hall, Marissa Rose
Publisher: name: University of British Columbia
Year: 2023

description: Self-regulation involves individuals’ abilities to adapt cognitions, affect, and behaviors to respond to environmental demands and achieve goals. During childhood, self-regulation describes how children co-ordinate their deployment of basic executive functions and higher order process (e.g., metacognition, motivation, strategic action) to effectively engage with parents and siblings at home, and with teachers and peers, while learning in school. Research spanning the fields of developmental and educational psychology provides empirical support illustrating how children’s self-regulation predicts school adjustment. However, studies also reveal that children differ in their engagement in self-regulation in school, but fewer studies have examined the development of young children’s self-regulation in school trajectories, and how they may be shaped by features of classroom contexts that can serve to impact it. The current study fills a gap in the literature by using longitudinal data to examine trajectories of three young children’s self-regulation in school from Kindergarten to Grade Five. This longitudinal case study asks three research questions. First, how did the case study students’ self-regulation and achievement trajectories change from Kindergarten through Grade 5? Second, how might supports for self-regulation in classrooms attenuate for risk in children’s development of self-regulation? Third, how might classroom supports for self-regulation differentially support emotion regulation (ER), self-regulated learning (SRL), and socially responsible self-regulation (SRSR) in the case study students? Results from this study demonstrated that, in general, trajectories of self-regulation and achievement show similar patterns (i.e., when self-regulation scores increase or decrease so do achievement ratings). However, each student’s trajectory is unique and context needs to be considered when thinking about children’s development of self-regulation. This study suggests that certain classroom contexts and teaching practices provide more support for students’ development of self-regulation. These practices are discussed in detail in the results section. Implications for research and practice, as well as future directions, are also presented.
title: THE EFFECTS OF ESCALATED FENTANYL INTAKE ON DECISION-MAKING DYNAMICS

description: Opioid Use Disorder is characterized partially as a decision-making disorder. Decision-making theories, such as habit theory and relative value theory, have aimed to better understand the shift in preference for drug over other alternatives. In order to compare these two contrasting theories, an allomorphic concurrent choice task will run in tandem with an escalation procedure. Male and female Sprague-Dawley rats were tested for choice differences in an allomorphic choice procedure. Reward dimensions, such as relative reward rate, were manipulated within sessions, and magnitude (remifentanil dose), was manipulated between sessions. To study the effects of escalated fentanyl intake on relative valuation, rats completed choice procedures in the morning, followed by either 1-hr or 6-hr access to fentanyl in the afternoon.

Escalation of fentanyl intake was evident in the 6-hr fentanyl access group, meanwhile fentanyl intake remained stable in the 1-hr fentanyl group. Choice behavior between 1-hr and 6-hr fentanyl access groups did not differ, however model comparison differences were found such that the model that included food-condition best described escalation data, but not choice data. This major finding indicates that value-based decision-making processes remained intact in 6-hr fentanyl access rats despite escalated intake of fentanyl, thus failing to support habit theory.

description: Whilst ageing in place is considered important for a healthier and a
      better quality of life for older people, there is yet a dearth of evidence
      on how older people with dementia negotiate and experience the wider
      community. The aim of the present study is therefore to explore
      experiences of social and spatial engagement in the wider community for
      people living with dementia in order to advance understandings of how
      their interactions in and with community settings impact on their health
      and wellbeing. Drawing on the theoretical framework of therapeutic
      landscapes and a sensory ethnographic methodology, I provide social,
      embodied and symbolic accounts of people’s everyday experiences and
      pursuits of health and wellbeing within their neighbourhood and beyond. An
      in-depth examination of socio-spatial interactions of nine people with
      dementia, seven of whom participated with family carers, is conducted by
      use of innovative interview methods (including photo-elicitation and
      walking interviews), participant observations and participant ‘diaries’
      (kept for a period of four weeks).

      The thesis presents three broad themes relating to participants’
      interactions with and experiences of places beyond the home- the diverse
      and changing nature of people’s personal circumstances and conceptions of
      health and wellbeing; the interrelationship between people’s changing
      health needs, lifestyle choices and geographical area of activities and
      finally the social, physical and symbolic processes through which people
      maintain a sense of normality and stay connected. Together these themes
      illustrate the significance of a variety of places to the lives of people
      with dementia. The ‘shrinking world’ analogy associated with experiences
      of dementia is thereby considered through a more focused discussion on the
      active role people with dementia play in shaping their life worlds and
      their everyday interactions to meet their health and wellbeing needs.
      Further, by applying the concept of therapeutic landscape to experiences
      of people with dementia in the wider community, this thesis makes an
      important contribution to dementia research whilst also suggesting new
      directions for the therapeutic landscape scholarship.
Electromagnetic field bumps: Electro-gravitational models of the classical electron and dark energy
Creators: name: Marx, Pierre
Publisher: name: arXiv
Year: 2023
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Previously we conjectured that extremely high Electromagnetic (EM) fields in a vacuum generate a gravitational field that causes Maxwell's equations to no longer be linear. This results in a "4-force" in the field configuration space, also called "four-current density". Based on the 4-current density, we postulate that the electric charge is the result of a high EM field. Considering the electrostatic potential with central symmetry and with the assumption that it cannot exceed the Planck potential, we show that the associated electric charge is confined inside a sphere with non-zero radius, centered at the origin. We propose to represent this elementary charge e, thus replacing the point electron of the standard model with a "bump" of the EM field. According to this model, the gravitational field created by EM is repulsive up to the classical radius of the electron, then attractive beyond. This property provides a model for dark energy, which is believed to cause the accelerated expansion of the universe and whose nature is unknown today. We thus replace the cosmological constant of the standard model ΛCDM by a "field of EM bumps".

Filipino Chaplains' Shift to Online Ministry: A Transcendental Phenomenological Study on Evolving Church Communication
Creators: name: Gaston, Gregory Ramon

Year: 2022
Subjects: chaplains filipinos online on-line ministry church communication phenomenology phenomenological Catholic

description: Using a transcendental phenomenology approach, six Filipino chaplains in Italy were interviewed as to their lived experiences in: (1) their shift to online ministry, (2) the response of the faithful to this shift, and (3) their sense of fulfilment during this shift. The shift to online ministry was viewed as part of the evolution of Church communication. Church ministry has always involved close contact with the people. The shift to online ministry has, to some extent, brought such contact even closer. This reflects the ongoing evolution in Church communication, from the limited oral and written means at the beginning, to systematic manual copying of Bibles and other early manuscripts, to printing, stage presentations, radio, TV, cinema and to the current use of Information and Communications Technology (ICT). This evolution was accelerated by lockdown measures brought about by Covid-19. ICT use is seen not as a replacement but rather a complement to face to face communication. Results of this study also suggest that as the migrants, chaplains, Government and Church engage in dialogue with each other, the virus itself as the object of the experience, creates the reality of the phenomenon. Communication does not only convey reality, but creates it. The virus communicated fear to everyone, creating a pandemic reality. The people responded to the virus through the lockdown, stringent policies, safety protocols, constant communication with each other and the shift to online ministry. The study revealed that in response to the shift the migrants, in coordination with their chaplains, spontaneously created online groups for prayers, formation, updating, and reaching out to those in need, whether they were Catholics or not. Chaplains suffered the same stress as others but needed to keep strong to continue to accompany and serve the migrants in line with their ministry. Part of their fulfillment as chaplains was being able to reach more people despite the pandemic using ICT, a practice that continued even after the lockdown. Understanding these chaplains’ experiences would help other chaplains in their own shift to online ministry. Standard operating procedures could be designed to encourage and facilitate such shift among other chaplains as needed. Data can eventually be organized into information and new lived knowledge to enhance chaplains’ ministry. This study also recommends further exploration into the transcendental phenomenological method as applied in the field of Church communications, specifically in the ministry of the clergy.
Controllable, driven phase transitions in the Fractional quantum Hall states in bilayer graphene

description: Here we report from our theoretical studies that in biased bilayer graphene, one can induce phase transitions from an incompressible fractional quantum Hall state to a compressible state by tuning the bandgap at a given electron density. The nature of such phase transitions is different for weak and strong inter-layer coupling. Although for strong coupling more levels interact there are lesser number of transitions than for the weak coupling case. The intriguing scenario of tunable phase transitions in the fractional quantum Hall states is unique to bilayer graphene and never before existed in conventional semiconductor systems.

description: This paper explores privacy-compliant group-level emotion recognition ''in-the-wild'' within the EmotiW Challenge 2023. Group-level emotion recognition can be useful in many fields including social robotics, conversational agents, e-coaching and learning analytics. This research imposes itself using only global features avoiding individual ones, i.e. all features that can be used to identify or track people in videos (facial landmarks, body poses, audio diarization, etc.). The proposed multimodal model is composed of a video and an audio branches with a cross-attention between modalities. The video branch is based on a fine-tuned ViT architecture. The audio branch extracts Mel-spectrograms and feed them through CNN blocks into a transformer encoder. Our training paradigm includes a generated synthetic dataset to increase the sensitivity of our model on facial expression within the image in a data-driven way. The extensive experiments show the significance of our methodology. Our privacy-compliant proposal performs fairly on the EmotiW challenge, with 79.24% and 75.13% of accuracy respectively on validation and test set for the best models. Noticeably, our findings highlight that it is possible to reach this accuracy level with privacy-compliant features using only 5 frames uniformly distributed on the video.
Living and learning with disabilities in Nigeria : an ecological narrative inquiry
Creators: name: Anokwuru, Joann Ihuoma
Publisher: name: University of British Columbia

description: Despite Nigeria’s policies on inclusive education, a gap exists between the word in policy and deed for people with disabilities. This qualitative study draws upon narratives of young people with disabilities, parents, special educators and a policymaker who recount their experiences within and around the Nigerian educational system. Bronfenbrenner’s bioecological theory of human development serves as a framework to situate and contextualize their particular experiences by considering broader socio-cultural influences, as well as immediate environments, such as family and school. In moving toward inclusive education in Nigeria, areas of focus are recommended, and an ecology of inclusive education with practical pathways is proposed. The fifteen participants in the study were selected to bring together relevant and diverse insights into past and current educational challenges within existing structures and future possibilities for people with disabilities in Nigeria. Each voice was positioned within a socio-cultural context and ecology of interrelated environments related to the individual, the family, the school, and public policy. Across the four groups of participants, voices were treated distinctly, represented in dialogue form, collective narratives and particular excerpts to situate, contextualize and personalize nuances of the journeys they chose to share. Each contributed to a larger narrative of stories, conceptions, practices and recommendations in this study. General themes across the narratives include experiences related to stigma, inclusivity, barriers, and support resources. Other themes focused on particular experiences of young adults with disabilities and their parents such as uncertainty, sacrifice, insufficient funding, changing schools, and the lack of educational resources and special educators. From the data, three priority areas of focus with eight recommendations were generated: stigma (prevalence, intervention), professional development for educators (rights-based frameworks, inclusive education) and the government’s role in inclusive education (reliable data, targeted funding, accessible language). Finally, an ecology of inclusive education, as a framework, submits that courses of action and intervention strategies target multiple structures and environmental influences together rather than a focus on exclusive ones. This study concludes that implementing inclusive education will be a significant step in achieving Nigeria’s policies in tackling discrimination against people living with disabilities and achieving inclusive education for all.

description: Electroweak radiative corrections give rise to large negative, double-logarithmically enhanced corrections in the TeV region. These are partly compensated by real radiation and, moreover, affected by selecting isospin-noninvariant external states. We investigate the impact of real gauge boson radiation more quantitatively by considering different restricted final state configurations. We consider successively a massive abelian gauge theory, a spontaneously broken SU(2) theory and the electroweak Standard Model. We find that details of the choice of the phase space cuts, in particular whether a fraction of collinear and soft radiation is included, have a strong impact on the relative amount of real and virtual corrections.

Year: 2017

description: This thesis seeks to investigate the global paradigm that exists in the War on Terror. It will do so over several steps, starting with the second chapter which will first document the history, both in the field of International Relations and of global politics, before 9/11. Afterward it discusses the international reaction and immediate war strategies of the War on Terror. The following section will go into the nuances of the War on Terror that make it distinct from other wars and make it harder to explain by legal and political scholars. In Chapter 3, various research of the State of Exception theory will be presented, including that of: John Locke, Carl Schmitt, Nicos Poulantzas, Michel Foucault, and Giorgio Agamben. This section highlights the strengths of Agamben’s theory over the others in looking at the War on Terror paradigm. In Chapter 4, the Agambenian State of Exception theory will be applied to the empirical reality of the War on Terror. In the Conclusion chapter, this research will reflect on the overall implications that the extra-legal paradigm of State of Exception has on human rights, while also discussing how the theory can be improved to reflect the true globality of the systems in act.

description: Across countless marine invertebrates, coordination of closely spaced swimming appendages is key to producing diverse locomotory behaviors. Using a widespread mechanism termed hybrid metachronal propulsion, mantis shrimp swim by moving five paddle-like pleopods along their abdomen in a posterior to anterior sequence during the power stroke and a near-synchronous motion during the recovery stroke. Despite the ubiquity of this mechanism, it is not clear how hybrid metachronal swimmers coordinate and modify individual appendage movements to achieve a range of swimming capabilities. Using high-speed imaging, we measured pleopod kinematics of mantis shrimp (Neogonodactylus bredini) while they performed two swimming behaviors: burst swimming and taking off from the substrate. By tracking each of the five pleopods, we tested how stroke kinematics vary across swimming speeds and the two swimming behaviors. We found that mantis shrimp achieve faster swimming speeds through a combination of higher beat frequencies, smaller stroke durations, and partially via larger stroke angles. The five pleopods exhibit non-uniform kinematics that contribute to the coordination and forward propulsion of the whole system. Micro-hook structures (retinacula) connect each of the five pleopod pairs and differ in their attachment across pleopods – possibly contributing to passive kinematic control. We compare our findings in N. bredini to previous studies to identify commonalities across hybrid metachronal swimmers at high Reynolds numbers and centimeter scales. Through our large experimental dataset and by tracking each pleopod's movements, our study reveals key parameters by which mantis shrimp adjust and control their swimming, yielding diverse locomotor abilities.

description: Do cell phones, household electrical power wiring or appliance, or high voltage power lines cause cancer? Fuggedaboudit! No way! When pigs fly! When I'm the Pope! Don't text while you're driving, however, or eat your cell phone. All organisms absorb microwave radiation directly as thermal energy. In living organisms, the organisms' thermal control systems, including the blood flow, and various cooling mechanisms, such as sweating in humans, that work to maintain a stable body temperature rapidly transfer the absorbed energy to the environment. Any temperature rise is small or even unobserved. Any proposed mechanism by which cell phone radiation might cause cancer must begin with this fact. But the amount of radiation absorbed from a cell phone is less than that produced by normal metabolic processes, and much less than that produced by, for example, exercise. None of these normal metabolic processes cause cancer. Therefore, the much smaller amounts of energy from cell phones doesn't cause cancer either. All forms of electromagnetic energy that are known carcinogens are ionizing; ultraviolet, X-rays, and gamma rays. Microwave radiation cannot ionize any physiological molecule. In fact, microwave radiation cannot directly break or modify any chemical bond, covalent or weak. Therefore, microwaves cannot initiate any process leading to cancer, unless it does so through thermal mechanisms. All chemical bonds that act in physiological processes must operate correctly in the thermal environment of the cells at body temperature. All of them have bond energy that is greater than that arising from the thermal jostling, vibrating, and rotating of the cytoplasm. Energy added by microwave radiation is more than a thousand times weaker than that present in the normal thermal jiggling. Since the normal thermal environment does not cause cancer, neither does any absorbed microwave radiation.

description: Das exponentielle Wachstum des wissenschaftlichen Outputs erhöht stetig den Bedarf an zuverlässigen Messgrößen zur effizienten Beurteilung von wissenschaftlichen Arbeiten. Traditionell werden Zitationen und zitationsbasierte Indikatoren wie der Journal Impact-Faktor oder der h-Index genutzt. Neben diesen bibliometrischen Faktoren bieten neue Technologien und Arbeitsweisen in der Wissenschaft eine Vielfalt von webbasierten Indikatoren um den Einfluss von Forschung („Impact“] messbar zu machen, z. B. Altmetrics oder Nutzungszahlen. Viele Forschende verfolgen die Nutzung dieser quantitativen Messgrößen mit verständlicher Skepsis.

Innerhalb des *metrics Projektes führen wir quantitative und qualitative Studien in Form von Interviews, Umfragen und interaktiven Experimenten durch, um herauszufinden wie Forschende Metriken gegenüberstehen und diese selbst nutzen. Wir möchten verbreitete Missverständnisse, die zur Fehlinterpretation von Metriken führen können, ebenso aufdecken wie latente Barrieren, die Forschende davon abhalten, Metriken in ihrer vollen Bandbreite anzuwenden.

Erste Ergebnisse zeigen, dass das fehlende Wissen über eine Vielzahl von Impact Metriken Forschende von deren Nutzung abhält. Dem könnte durch die Aufnahme in Ausbildungsinhalte entgegengewirkt werden. Ebenso zeigen erste Analysen substantielle Unterschiede in der Bewertung der Nützlichkeit unterschiedlicher Metriken, wobei bibliometrische Kenngrössen weit eher als nutzbringende Indikatoren für wissenschaftliche Relevanz angesehen werden als web-basierte Metriken.

Die Studienergebnisse bieten wertvolle Orientierung im unübersichtlichen Dickicht der existierenden Indikatoren für wissenschaftlichen Impact, zeigen welche Vorbehalte von Forschenden berücksichtigt werden sollten, wenn Metriken im Bereich der Performance-Messung herangezogen und kommuniziert werden und geben Empfehlungen zur Verbesserung der Nützlichkeit von Metriken als Hilfsmittel für Forschungsevaluation.

description: Quantum mechanics and gravitation are two pillars of modern physics. Despite their success in describing the physical world around us, they seem to be incompatible theories. There are suggestions that one of these theories must be generalized to achieve unification. For example, Born's rule, one of the axioms of quantum mechanics could be violated. Born's rule predicts that quantum interference, as shown by a double slit diffraction experiment, occurs from pairs of paths. A generalized version of quantum mechanics might allow multi-path, i.e. higher order interferences thus leading to a deviation from the theory. We performed a three slit experiment with photons and bounded the magnitude of three path interference to less than 10-2 of the expected two-path interference, thus ruling out third and higher order interference and providing a bound on the accuracy of Born's rule. Our experiment is consistent with the postulate both in semi-classical and quantum regimes.

description: We analyze the Ericksen-Leslie system equipped with the Oseen-Frank energy in three space dimensions. The new concept of dissipative solutions is introduced. Recently, the author introduced the concept of measure-valued solutions to the considered system and showed global existence as well as weak-strong uniqueness of these generalized solutions. In this paper, we show that the expectation of the measure valued solution is a dissipative solution. The concept of a dissipative solution itself relies on an inequality instead of an equality, but is described by functions instead of parametrized measures. These solutions exist globally and fulfill the weak-strong uniqueness property. Additionally, we generalize the relative energy inequality to solutions fulfilling different nonhomogeneous Dirichlet boundary conditions and incorporate the influence of a temporarily constant electromagnetic field. Relying on this generalized energy inequality, we investigate the long-time behavior and show that all solutions converge for the large time limit to a certain steady state.

description: Using a combination of dielectric spectroscopy and solid-state deuteron NMR, the hydration water dynamics of connective tissue proteins is studied at sub-ambient temperatures. In this range, the water dynamics follows an Arrhenius law. A scaling analysis of dielectric losses, 'two-phase' NMR spectra, and spin-lattice relaxation times consistently yield evidence for a Gaussian distribution of energy barriers. With the dielectric data as input, random-walk simulations of a large-angle, quasi-isotropic water reorientation provide an approximate description of stimulated-echo data on hydrated elastin. This secondary process takes place in an essentially rigid energy landscape, but in contrast to typical β-relaxations it is quasi-isotropic and delocalized. The delocalization is inferred from previous NMR diffusometry experiments. To emphasize the distinction from conventional β-processes, for aqueous systems such a matrix-decoupled relaxation was termed a ν-process. It is emphasized that the phenomenology of this time-honored, 'new' process is shared by many non-aqueous binary glasses in which the constituent components exhibit a sufficient dynamical contrast.

description: This scoping review seeks to explore methodologies in previous studies’ which use nails as a biomarker for fluoride content. Specifically, the collection, preparation, and analytical procedures, to identify variance in protocols that may affect the final fluoride content determination. Fluoride is ubiquitous in the environment and therefore people’s diet and bodies. Although fluoride is beneficial in preventing dental caries, excess fluoride can cause dental fluorosis, skeletal fluorosis, and it may be associated with negative impact on cognitive function. Due to this, there has been an increase in studies determining fluoride content in biomarkers, including nail clippings, to be related with health outcomes, calling for more consistency in protocols. This review attempts to identify variance in the collection, preparation, and analysis of fluoride in nails in order to aid in the creation of a standardized protocol.

description: We have observed warm molecular hydrogen in two nearby edge-on disk galaxies, NGC 4565 and NGC 5907, using the Spitzer high-resolution infrared spectrograph. The 0-0 S(0) 28.2 micron and 0-0 S(1) 17.0 micron pure rotational lines were detected out to 10 kpc from the center of each galaxy on both sides of the major axis, and in NGC 4565 the S(0) line was detected at r = 15 kpc on one side. This location lies beyond a steep drop in the radio continuum emission from cosmic rays in the disk. Despite indications that star formation activity decreases with radius, the H2 excitation temperature and the ratio of the H2 line and the far-IR luminosity surface densities, Sigma_L(H2}/Sigma_L(TIR}, change very little as a function of radius, even into the diffuse outer region of the disk of NGC 4565. This suggests that the source of excitation of the H2 operates over a large range of radii, and is broadly independent of the strength and relative location of UV emission from young stars. Although excitation in photodissociation regions is the most common explanation for the widespread H2 emission, cosmic ray heating or shocks cannot be ruled out. The inferred mass surface densities of warm molecular hydrogen in both edge-on galaxies differ substantially, being 4(-60) M_solar/pc^2 and 3(-50) M_solar/pc^2 at r = 10 kpc for NGC 4565 and NGC 5907, respectively. The higher values represent very unlikely point-source upper limits. The point source case is not supported by the observed emission distribution in the spectral slits. These mass surface densities cannot support the observed rotation velocities in excess of 200 km/s. Therefore, warm molecular hydrogen cannot account for dark matter in these disk galaxies, contrary to what was implied by a previous ISO study of the nearby edge-on galaxy NGC 891.

description: The U.S. Marine Mammal Protection Act (MMPA) requires that stocks of marine mammal species in U.S. waters be maintained at or above their optimum sustainable population level (OSP), defined as the number of animals which results in the maximum net productivity. To meet this requirement for each stock, the U.S. National Marine Fisheries Service (NMFS) estimates annual human-caused mortality and potential biological removal (PBR), the maximum number of animals that may be removed from a stock due to human activities ( e.g., fisheries bycatch) while allowing the stock to reach or maintain its OSP.

description: A comprehensive comparison between the magnetic field- and temperature-dependent low frequency spin dynamics in the antiferromagnetic spin-1/2 Heisenberg chain (AFHC) system copper pyrazine dinitrate, probed via the 13C-nuclear magnetic resonance (NMR) relaxation rate 1/T1, and the field theoretical approach in the Luttinger liquid (LL) regime has been performed. We have found a very good agreement between the experiment and theory in the investigated temperature and field range. Our results demonstrate how strongly the quantum critical point affects the spin dynamics of Heisenberg spin chain compounds.

description: This work presents the results of experimental laboratory tests on the apodization of circular and rectangular apertures using the Interferometric Apodization by Homothety (IAH) technique. The IAH approach involves splitting the amplitude of the instrumental PSF into two equal parts. One of the two produced PSFs undergoes a homothety to change its transverse dimensions while its amplitude is properly controlled. The two PSFs are then combined to produce an apodized image. The diffraction wings of the resulting PSF are subsequently reduced by some variable reduction factor, depending on an amplitude parameter $γ$ and a spread parameter $η$. This apodization approach was implemented in the laboratory using an interferometric setup based on the Mach-Zehnder Interferometer (MZI). The experimental results exhibit a strong agreement between theory and experiment. For instance, the average experimental contrast obtained at a low angular separation of $2.4λ/D$ does not exceed $5\times10^{-4}$. This work also allowed us to study the influence on the apodizer's performance of some parameters such as the wavelength and the density of the neutral filters.

description: The mechanisms giving rise to diffuse radio emission in galaxy clusters, and in particular their connection with cluster mergers, are still debated. We aim to obtain new insights into the internal dynamics of the cluster Abell 2294, recently shown to host a radio halo. Our analysis is mainly based on redshift data for 88 galaxies acquired at the Telescopio Nazionale Galileo. We also use new photometric data acquired at the Isaac Newton Telescope and X-ray data from the Chandra archive. We re-estimate the redshift of the large, brightest cluster galaxy (BCG) obtaining =0.1690. We estimate a quite large LOS velocity dispersion sigma_V about 1400 km/s and X-ray temperature T_X about 10 keV. Our optical and X-ray analysis detects evidence for substructure. Our results are consistent with the presence of two massive subclusters separated by a LOS rest frame velocity difference V_rf about 2000 km/s, very closely projected in the plane of sky along the SE-NW direction. The observational picture, interpreted through the analytical two-body model, suggests that Abell 2294 is a cluster merger elongated mainly in the LOS direction and catched during the bound outgoing phase, a few fractions of Gyr after the core crossing. We find Abell 2294 is a very massive cluster with a range of M=2-4 10E15 M_sun. Moreover, contradicting previous findings, our new data do exclude the presence of the H$α$ emission in the spectrum of the BCG galaxy. The outcoming picture of Abell 2294 is that of a massive, quite "normal" merging cluster, as found for many clusters showing diffuse radio sources.
