description: Laser Doppler holography (LDH) is an interferometric blood flow imaging technique based on full-field measurements of the Doppler spectrum. LDH has so far been demonstrated in the retina with ultrafast cameras, typically at 75 kHz. We show here that a similar method can be implemented with camera frame rates 10 times slower than before. Thanks to energy conservation, low and high frequency local power Doppler signals have opposite variations, and a simple contrast inversion of the low frequency power Doppler reveals fast blood flow beyond the camera detection bandwidth for conventional laser Doppler measurements. Relevant blood flow variations and color composite power Doppler images can be obtained with camera frame rates down to a few kHz.

description: A long-standing problem with the many-body approximations for interacting condensed bosons has been the dichotomy between the ``conserving'' and ``gapless'' approximations, which either obey the conservations laws or satisfy the Hugenholtz-Pines condition for a gapless excitation spectrum, in the order. It is here shown that such a dichotomy does not exist for a system of composite bosons, which form as bound-fermion pairs in the strong-coupling limit of the fermionic attraction. By starting from the constituent fermions, for which conserving approximations can be constructed for any value of the mutual attraction according to the Baym-Kadanoff prescriptions, it is shown that these approximations also result in a gapless excitation spectrum for the boson-like propagators in the broken-symmetry phase. This holds provided the corresponding equations for the fermionic single- and two-particle Green's functions are solved self-consistently.

description: Concepts explaining the wage‐price nexus in Bangladesh are diverse and conflicting. A proper understanding of the relationship between food prices and rural wages is essential for planning policies in support of the rural poor. In exploring the link between food prices and rising agricultural wages, this study analyzes the dynamic relations between those two by using monthly data from 1994 to 2014. A standard vector error correction model (VECM) is implemented to determine the short‐run and long‐run relationships between wages and food prices in eight divisions in Bangladesh. In addition, we use autoregressive distributed lag (ARDL) models to estimate the pass‐through coefficients and to compare the short‐run effects of rice price and urban wage shocks on agricultural wages. We find statistical evidence for a structural break between January 2007 and January 2009 in the relationships of the variables in all divisions. After the structural break, in six out of eight divisions, any shock in rice prices does not transmit to the farm wages in the short‐run. Moreover, our findings show that in the long‐run food prices have become less influential in explaining the changes in rural wages while the influence of urban wages has become stronger in some divisions.

description: The challenging problems that the hegelian lectures on the history of philosophy pose are reviewed and investigated in this study in the light of their origins, historical background, their Introduction and their section on german idealism. A connection with certain modern issues in the history of philosophy is delineated and German Idealism, the principal work of Fredercik Beiser on the releveant period, is presented, so as to provide a concrete case through which a modern outlook on the subject be featured. A final line of questioning refers to the relation between the lectures and the broader hegelian ouevre, and its importance for their valid appreciation.
Splash Bridge Models of Inclined, Gas-Rich, Direct Galaxy Collisions

description: Splash bridges are formed from the direct inelastic collision of gas-rich galaxies. Recent multi-wavelength observations of the Taffy galaxies, UGC 12914/15, have revealed complicated gas structures in the bridge. We have upgraded the sticky particle simulation code of Yeager et al., 2019, by adding: the ability to adjust the relative inclination of the gas discs, the ability to track cloud-cloud collisions over time, and additional cooling processes. Inclination effects lead to various morphological features, including filamentary streams of gas stripped from the smaller galactic disc. The offset of disc centres at impact determines whether or not these streams flow in a single direction or multiple directions, even transverse to the motion of the two galaxies. We also find that, across many types of direct collision, independent of the inclination or offset, the distributions of weighted Mach numbers and shock velocities in colliding clouds relax to a very similar form. There is good evidence of prolonged turbulence in the gas of each splash bridge for all inclinations and offsets tested, as a result of continuing cloud collisions, which in turn are the result of shearing and differentially accelerated trajectories. The number distribution of high velocity shocks in cloud collisions, produced in our low inclination models, are in agreement with those observed in the Taffy Galaxies with ALMA, Appleton et al., 2019.
Search for High Energy Gamma Rays from an X-ray Selected Blazar Sample

description: Our understanding of blazars has been greatly increased in recent years by extensive multi-wavelength observations, particularly in the radio, X-ray and gamma-ray regions. Over the past decade the Whipple 10m telescope has contributed to this with the detection of 5 BL Lacertae objects at very high gamma-ray energies. The combination of multi-wavelength data has shown that blazars follow a well-defined sequence in terms of their broadband spectral properties. Together with providing constraints on emission models, this information has yielded a means by which potential sources of TeV emission may be identified and predictions made as to their possible gamma-ray flux. We have used the Whipple telescope to search for TeV gamma-ray emission from eight objects selected from a list of such candidates. No evidence has been found for VHE emission from the objects in our sample, and upper limits have been derived for the mean gamma-ray flux above 390GeV. These flux upper limits are compared with the model predictions and the implications of our results for future observations are discussed.

There is clear evidence of a strong anomalous Hall effect as expected from a 4f conduction channel, supported by an optical absorption into a 4f or 4f/5d hybridized tail at the base of the conduction band. The results reveal a heavy-fermion 4f/5d band lying where it can be occupied at controllable levels with nitrogen-vacancy donors.

description: We derive the asymptotic symmetries of the manifestly duality invariant formulation of electromagnetism in Minkoswki space. We show that the action is invariant under two algebras of angle-dependent $u(1)$ transformations, one electric and the other magnetic. As in the standard electric formulation, Lorentz invariance requires the addition of additional boundary degrees of freedom at infinity, found here to be of both electric and magnetic types. A notable feature of this duality symmetric formulation, which we comment upon, is that the on-shell values of the zero modes of the gauge generators are equal to only half of the electric and magnetic fluxes (the other half is brought in by Dirac-string type contributions). Another notable feature is the absence of central extension in the angle-dependent $u(1)^2$-algebra.

description: This paper examines the state, drivers and, consequently, the impacts of agricultural mechanization in eleven countries in Africa. Using representative multistage stratified household survey data and robust analytical approaches, findings show light hand-held tools and equipment remain the main type of machinery in most countries – about 48% of the sampled households have access to light machinery compared to 35% that have access to animal-powered machinery, and only about 18% that use tractor-powered machinery. Significant drivers of agricultural mechanization include the size of the household, gender of the household head, participation in off-farm economic activities, distance to the input and output markets, farm size, land tenure, type of farming system, access to extension services, and use of fertilizer and pesticides. This study finds that after controlling for socio-economic, demographic, and regional determinants, agricultural mechanization, significantly increases the amount of cropland cultivated (extensification) and is also accompanied by input intensification especially in countries where land expansion is limited. We further find significant but mixed impact of agricultural mechanization on use of household and hired labor. Finally, agricultural mechanization significantly raises the productivity of maize and rice in all cases. These findings point to the importance of developing favorable arrangements that would avail mechanization to small and medium scale farmers. This would involve providing incentives for private sector to scale agricultural mechanization initiatives and targeting and engaging women farmers and the youth by investing in supportive infrastructure and training.

description: An elegant formula for coordinates of carbon atoms in a unit cell of a single-walled nanotube (SWNT) is presented and the potential of neon (Ne) inside an infinitely long SWNT is analytically derived out under the condition of the Lennard-Jones potential between Ne and carbon atoms. Specific heats of dilute Ne inside long (20, 20) SWNT are calculated at different temperatures. It is found that Ne exhibits 3-dimensional (3D) gas behavior at high temperature but behaves as 2D gas at low temperature. Especially, at ultra low temperature, Ne inside (20, 20) nanotubes behaves as lattice gas. A coarse method to determine the characteristic temperature $\mathcal{T}_c$ for low density gas in a potential is put forward. If $\mathcal{T}\gg \mathcal{T}_c$, we just need to use the classical statistical mechanics without solving the Shrödinger equation to consider the thermal behavior of gas in the potential. But if $\mathcal{T}\sim \mathcal{T}_c$, we must solve the Shrödinger equation. For Ne in (20,20) nanotube, we obtain $\mathcal{T}_c\approx 60$ K.

description: This paper explores the patterns of duration and survival of fresh fruit and vegetables import in New Zealand and identifies determinants of survival. Using a discrete-time survival model, we evaluate the impacts of partner-specific characteristics and New Zealand Import Health Standards (IHS) regulations on the survival of trade relationships with 87 economies from 1994 to 2017. Our findings indicate that while more than half of these trade relationships had only survived one year, approximately one-quarter had attempted to enter the market multiple times. Interestingly, the results reveal no evidence that IHS regulations have persistent effects on import survival

description: We perform a numerical analysis of the effects of a nonlinear perturbation on the quantum dynamics of two models describing non-interacting cold atoms in a standing wave of light with a periodical modulated amplitude $A(t)$. One model is the driven pendulum, considered in ref.\cite{raiz1}, and the other is a variant of the well-known Kicked Rotator Model. In absence of the nonlinear perturbation, the system is invariant under some discrete symmetries and quantum dynamical tunnelling between symmetric classical islands is found. The presence of nonlinearity destroys tunnelling, breaking the symmetries of the system. Finally, further consequences of nonlinearity in the kicked rotator case are considered.

description: Abstract:- Objective: The purpose of this paper is to report on enablers and barriers during the first 2 years of the health systems integration project that included the implementation of a health navigator role. The project aims to improve health outcomes for children and young people residing in out of home care in rural Australia with a health navigator co- located between child protection practitioners and community health services clinicians.Setting: Rural Northwest Victoria.Participants: Sunraysia Community Health Services and the Department of Health and Human Services.Design: The qualitative design of the project evaluation involved semi- structured interviews and documentary evidence analysis. Analyses of interviews and documentary data demonstrate the challenging nature of siloed service delivery in rural Australia, particularly during a time that comprised multiple interruptions due to COVID-19.Results: A limited synergy between organisational priorities and reporting systems hindered project progress. The lack of a shared definition of ‘health’ challenged the effective collaboration between health clinicians and child protection practitioners and the role of the health navigator. The health navigator raising health awareness through project involvement, training and sector- wide stakeholder engagement resulted in a slow but steady process of increased prioritisation of health care, increased health literacy among the child protection workforce, and broadening participation of area- based stakeholders, but did not translate to increased access to health plans for children. Conclusion: Integrating health systems across multiple sites with support of a health navigator revealed difficulties, particularly during COVID- 19. The first phase of the project demonstrated the value of shared governance and partnerships as an imperative foundation for fundamental change. Relationships strengthened throughout the project, leading to a better understanding of area- based strengths, which in turn supports improved pathways to health care for children and young people in OOHC within rural communities and driving the subsequent phases of the 10-year project.

description: The accurate flux calibration of observational data is vital for astrophysics and cosmology because absolute flux uncertainties of stellar standards propagate into scientific results. With the ever higher precision achieved by telescopic missions (e.g. JWST) in the infrared (IR), suitable calibrators are required for this regime. The basis of the Hubble Space Telescope (HST) flux scale is defined by model fits of three hot (Teff > 30000 K) hydrogen-atmosphere (DA) white dwarfs, which achieve an accuracy better than 1 per cent at optical wavelengths but falls below this level in the IR range. We present a network of 17 cooler DA white dwarfs with Teff < 20000 K as spectrophotometric flux standards that are equally, if not more, accurate at IR wavelengths. Cooler white dwarfs do not suffer from non-local thermal equilibrium (NLTE) effects in continuum flux or from UV metal line blanketing, have a larger sky density, are generally closer to Earth with little or negligible interstellar reddening, and have energy distributions peaking in the optical or near-IR. Using the latest grid of DA LTE atmosphere models with three-dimensional (3D) convection, the observed Space Telescope Imaging Spectrometer (STIS) and Wide Field Camera three (WFC3) fluxes of our network are accurate to 3 per cent over most of the range 1450 - 16000 AA, with a median standard deviation of 1.41 per cent. Fitting the HST STIS and WFC3 white dwarf SEDs and Balmer lines independently yields SEDs that agree within 3$σ$, which demonstrates the precision of the models for our network.

description: A graviton of a nonzero mass and decay width propagates five physical polarizations. The question of interactions of these polarizations is crucial for viability of models of massive/metastable gravity. This question is addressed in the context of the DGP model of a metastable graviton. First, I argue that the well-known breakdown of a naive perturbative expansion at a low scale is an artifact of the weak-field expansion itself. Then, I propose a different expansion -- the constrained perturbation theory -- in which the breakdown does not occur and the theory is perturbatively tractable all the way up to its natural ultraviolet cutoff. In this approach the couplings of the extra polarizations to matter and their selfcouplings appear to be suppressed and should be neglected in measurements at sub-horizon scales. The model reproduces results of General Relativity at observable distances with high accuracy, while predicting deviations from them at the present-day horizon scale.

description: Oroxylin A, a major flavonoid in the extracts of Oroxylum indicum as well as Scutellaria baicalensis possesses useful medicinal properties. Many of the published routes claiming the synthesis of Oroxylin A (1) have in fact led to a regioisomer Negletein that was misinterpreted as Oroxylin A. In the present work, we describe a novel, straight-forward and scalable semi-synthetic approach for rapid access to the title compound, the structure of which is unambiguously secured by NMR and X-ray crystallographic analysis of a derivative. This work also encompasses the synthesis of a glycosylated derivative of Oroxylin A viz OAGME (2), which has marked pharmacological importance.

description: We argue that the complete Klebanov-Witten flow solution must be described by a Calabi-Yau metric on the conifold, interpolating between the orbifold at infinity and the cone over T^(1,1) in the interior. We show that the complete flow solution is characterized completely by a single, simple, quasi-linear, second order PDE, or "master equation," in two variables. We show that the Pilch-Warner flow solution is almost Calabi-Yau: It has a complex structure, a hermitian metric, and a holomorphic (3,0)-form that is a square root of the volume form. It is, however, not Kahler. We discuss the relationship between the master equation derived here for Calabi-Yau geometries and such equations encountered elsewhere and that govern supersymmetric backgrounds with multiple, independent fluxes.

description: The Visual Research Abstract (VRA) was initially conceived as a pedagogical strategy to assist undergraduate students to navigate and understand the structure of their dissertation and the theoretical activities relating to fashion research at its earliest stages. The paper is guided by action research and collects data using a structured online questionnaire across the third-year (L. 6) and second-year (L. 5) fashion students at a UK Arts University and is aimed to evaluate and refine the pedagogical method. The research explores the student experience regarding their application of the tool, and the proposed strategies for refinement. The findings reveal that the VRA is a useful pedagogical strategy in fashion education to navigate the theoretical structure of the written dissertation closely aligned to a student’s final major project. Consequently, this approach has been discussed in the paper and adopted by several subject disciplines within the Arts University environment.

description: Uncorrelated variability between direct X-ray continuum and reflection components (including the Fe line, if present) has been reported in many accreting black hole systems, challenging theoretical models of disc reflection. We explore a model based on gravitational light bending in the near vicinity of the central black hole in which the X-ray variability is controlled by the height of the primary source of X-rays above the accretion disc. The relationship between the direct power law component (PLC) and the reflection-dominated component (RDC) is not trivial and allows to identify three different regimes in which the RDC (and the Fe line) is correlated, anti-correlated or almost independent with respect to the PLC. X-ray observations of the active galaxy MCG-6-30-15 and the black hole candidate XTE J1650-500 (and possibly other sources, e.g. NGC 4051) reveal that a series of predictions are actually observed: the behaviour of the Fe line flux, profile, and EW and of the reflection fraction with respect to the continuum supports our model which may explain what are otherwise puzzling properties of these sources.

description: Σκοπός της διατριβής ήταν η μελέτη του μύθου της Πρόκνης και της Φιλομήλας από τις Μεταμορφώσεις του Οβιδίου. Ο μύθος, θίγοντας γεγονότα που απασχολούν την ανθρώπινη φύση, έχει παρακινήσει πολλούς καλλιτέχνες να ασχοληθούν μαζί του και να δώσουν τη δική τους ερμηνεία στα γεγονότα που διηγείται. Στην παρούσα εργασία ιχνηλατείται ο μύθος ακολουθώντας τρεις άξονες. Ο πρώτος άξονας, σχετίζεται με τον ίδιο τον μύθο τις παραλλαγές του και τις πηγές του. Ο δεύτερος άξονας περιστρέφεται γύρω από την ΓΥΝΑΙΚΑ ως αποδέκτη αλλά και ως δημιουργό απάνθρωπων πράξεων. Ο τρίτος άξονας θα περιοριστεί στην μετεγγραφή του μύθου στην σύγχρονη δραματουργία, καθώς και την διερεύνηση των παραστάσεων περιπατητικού χαρακτήρα προκειμένου, να εξηγηθούν οι λόγοι οι οποίοι οδήγησαν στη συγγραφή της παρούσας εργασίας και τη σκηνική επιλογή της παράστασης Το κορίτσι στο σκοτεινό δάσος.

description: The purpose of the present thesis was the study of the legend of Procne and Philomela from Ovid’s Metamorphoses. The legend, by affecting events that interest the human nature, has motivated many artists to get involved with him and give their own interpretation on the events that he narrates. In this essay the legend is being traced by following three axes. The first axis is associated with the legend himself, the variations and its sources. The second axis is rotating around the WOMAN as a receiver but also as a maker of inhuman actions. The third axis will be limited in the transfer of the legend in the modern dramatologies and the investigation of the walking character in order to explain the reasons that led to the writing of this essay and the scenic choice of the show The girl in the dark forest.

description: Electron-phonon coupling, diagonal in a real space formulation, leads to polaron paradigm of smoothly varying properties. However, fundamental changes, namely the singular behavior of polarons, occur if non-diagonal pairing is involved into consideration. The study of polaron transformations and related properties of matter is of particular interest for realistic models, since competition between diagonal and non-diagonal electron-phonon contributions in the presence of other strong interactions can result in unconventional behavior of the system. Here we consider the multiband pd-model of cuprate superconductors with electron-phonon interaction and analyze the features of the systems that are caused by the competition of diagonal and non-diagonal electron-phonon contributions in the limit of strong electron correlations. Using the polaronic version of the generalized tight-binding method, we describe the evolution of the band structure, Fermi surface, density of states at Fermi level, and phonon spectral function in the space of electron-phonon parameters ranging from weak to strong coupling strength of the adiabatic limit. On the phase diagram of polaron properties we reveal two quantum phase transitions and show how electron-phonon interaction gives rise to Fermi surface transformation (i) from hole pockets to Fermi arcs and (ii) from hole to electron type of conductivity. We also demonstrate the emergence of new states in the phonon spectral function of the polaron and discuss their origin.

description: Η αλλαγές που προμηνύονται για τον τρόπο ζωής των ανθρώπων λόγω των γενικότερων συνθηκών σε περιβαλλοντικά θέματα όπως η κλιματική αλλαγή απαιτούν αποφάσεις που θα δίνουν πραγματοποιήσιμες λύσεις. Μέσα σε αυτό το πλαίσιο η δημιουργία νέων παραγωγικών μοντέλων κρίνεται απαραίτητο να συνδυάζει τα οικονομικά οφέλη με την βιώσιμη διαχείριση των φυσικών πόρων και τη διατήρηση της βιοποικιλότητας. Νέα μοντέλα και στρατηγικές βιοοικονομίας εφαρμόζονται σε πολλά μέρη του κόσμου καθώς είναι φανερό ότι μπορούν να αποτελέσουν μέρος της λύσης. Η βιοοικονομία εμπεριέχει τεχνολογικές εξελίξεις και μεθόδους που διαμορφώνουν νέα παραγωγικά μοντέλα με χαμηλές περιβαλλοντικές επιπτώσεις. Σκοπός της εργασίας είναι να διερευνήσει με τη χρήση ενός ειδικά διαμορφωμένου ερωτηματολογίου τις απόψεις για βασικές πτυχές της βιοοικονομίας που υπάρχουν στον ερευνητικό-δημόσιο αλλά και στον ιδιωτικό τομέα της Ελλάδας. Η μέθοδος που ακολουθήθηκε ήταν αυτή της στατιστικής ανάλυσης των 71 συνολικά απαντήσεων του ερωτηματολογίου που συγκεντρώθηκαν το 2020 στην Ελλάδα. Από το σύνολο των απαντήσεων διακρίνεται ότι η δημιουργία μιας στρατηγικής για την βιοοικονομία θα μπορούσε να δώσει λύσεις σε εθνικά αλλά και περιβαλλοντικά προβλήματα. Παράλληλα αναδεικνύονται ζητήματα όπως τα περιβαλλοντικά οφέλη μιας βιοοικονομίας, οι τρόποι αξιοποίησης της βιομάζας στην χώρα καθώς και τα βασικότερα εμπόδια για την ανάπτυξη της βιοοικονομίας.
description: The predicted changes in people's way of living due to environmental subjects like climate change need decisions that are giving realistic solutions. Under these circumstances, the development of new production models is necessary to combine the economic gains with the sustainable management of natural resources and the protection of biodiversity. New models of bio-economy and related national strategies are taking place in many countries worlwide as they can be part of the solution. In the field of bio-economy, new technological innovations and methods with low environmental effects are taking place. Α questionnaire type of survey is used for the needs of the study, promoting the views from the scientific and the private sector around the different aspects of bio-economy in Greece. The statistical analysis was the selected method for the 71 answers of the survey implemented in 2020 in Greece. The importance of a bio-economy strategy at the national level is highlighted from the answers. At the same time, different kinds of issues are promoted related to the environmental approach of bio-economy, the exploitation of biomass, as also the main obstacles for the further development of bio-economy in Greece.
Error estimates for backward fractional Feynman-Kac equation with non-smooth initial data

description: In this paper, we are concerned with the numerical solution for the backward fractional Feynman-Kac equation with non-smooth initial data. Here we first provide the regularity estimate of the solution. And then we use the backward Euler and second-order backward difference convolution quadratures to approximate the Riemann-Liouville fractional substantial derivative and get the first- and second-order convergence in time. The finite element method is used to discretize the Laplace operator with the optimal convergence rates. Compared with the previous works for the backward fractional Feynman-Kac equation, the main advantage of the current discretization is that we don't need the assumption on the regularity of the solution in temporal and spatial directions. Moreover, the error estimates of the time semi-discrete schemes and the fully discrete schemes are also provided. Finally, we perform the numerical experiments to verify the effectiveness of the presented algorithms.

description: PDGF-CC is a member of the platelet-derived growth factor (PDGF) family that stimulates PDGFRα phosphorylation and thereby activates intracellular signalling events essential for development but also in cancer, fibrosis and neuropathologies involving blood-brain barrier (BBB) disruption. In order to elucidate the biological and pathological role(s) of PDGF-CC signalling, we have generated high affinity neutralizing monoclonal antibodies (mAbs) recognizing human PDGF-CC. We determined the complementarity determining regions (CDRs) of the selected clones, and mapped the binding epitope for clone 6B3. Using the monoclonal 6B3, we determined the expression pattern for PDGF-CC in different human primary tumours and control tissues, and explored its ability to neutralize PDGF-CC-induced phosphorylation of PDGFRα. In addition, we showed that PDGF-CC induced disruption of the blood-retinal barrier (BRB) was significantly reduced upon intraperitoneal administration of a chimeric anti-PDGF-CC antibody. In summary, we report on high affinity monoclonal antibodies against PDGF-CC that have therapeutic efficacy in vivo.

description: In order to explore the possibility of tuning superconducting and ferromagnetic transitions by Cu doping (for Ru) in GdSr2RuCu2O8, we have carried out synthesis and characterization of GdSr2Ru{1-x}Cu{2+x)O8 (x = 0, 0.05, 0.1, 0.2) and studied their physical properties. Coexistence of superconductivity and ferromagnetism is observed in all the Cu doped samples studied here. The zero field susceptibility data suggests formation of a spontaneous vortex phase. Cu doping decreases the ferromagnetic Curie temperature, whereas the superconducting transition temperature increases until an optimal concentration x~0.1. This reflects an increase in hole transfer to the CuO2 planes and reduction of ferromagnetic order within the ruthenate layers.
