description: It is well known that direct observation of interference and diffraction pattern in the intensity distribution requires a spatially coherent source. Optical waves emitted from portions beyond the coherence area possess statistically independent phases, and will degrade the interference pattern. In this paper we show an optical interference experiment, which seems contrary to our common knowledge, that the formation of the interference pattern is related to a spatially incoherent light source. Our experimental scheme is very similar to Gabor's original proposal of holography[1], just with an incoherent source replacing the coherent one. In the statistical ensemble of the incoherent source, each sample field produces a sample interference pattern between object wave and reference wave. These patterns completely differ from each other due to the fluctuation of the source field distribution. Surprisingly, the sum of a great number of sample patterns exhibits explicitly an interference pattern, which contains all the information of the object and is equivalent to a hologram in the coherent light case. In this sense our approach would be valuable in holography and other interference techniques for the case where coherent source is unavailable, such as x-ray and electron sources.

description: We demonstrate electrochemical top gating of graphene by using a solid polymer electrolyte. This allows to reach much higher electron and hole doping than standard back gating. In-situ Raman measurements monitor the doping. The G peak stiffens and sharpens for both electron and hole doping, while the 2D peak shows a different response to holes and electrons. Its position increases for hole doping, while it softens for high electron doping. The variation of G peak position is a signature of the non-adiabatic Kohn anomaly at $Γ$. On the other hand, for visible excitation, the variation of the 2D peak position is ruled by charge transfer. The intensity ratio of G and 2D peaks shows a strong dependence on doping, making it a sensitive parameter to monitor charges.

description: We study the existence of a maximal solution of $-\Gd u+g(u)=f(x)$ in a domain $\Gw\subset \BBR^N$ with compact boundary, assuming that $f\in (L^1_{loc}(\Gw))_+$ and that $g$ is nondecreasing, $g(0)\geq 0$ and $g$ satisfies the Keller-Osserman condition. We show that if the boundary satisfies the classical $C_{1,2}$ Wiener criterion then the maximal solution is a large solution, i.e., it blows up everywhere on the boundary. In addition we discuss the question of uniqueness of large solutions.

description: Likely candidates for the global potential energy minima of (H$_{2}$O)$_{n}$ clusters with $n\leq21$ on the (0001)-surface of graphite are found using basin-hopping global optimization. The potential energy surfaces are constructed using the TIP4P intermolecular potentials for the water molecules (the TIP3P is also explored as a secondary choice), a Lennard-Jones water-graphite potential, and a water-graphite polarization potential that is built from classical electrostatic image methods and takes into account both the perpendicular and parallel electric polarizations of graphite. This potential energy surface produces a rather hydrophobic water-graphite interaction. As a consequence, the water component of the lowest graphite-(H$_{2}$O)$_{n}$ minima is quite closely related to low-lying minima of the corresponding TIP4P (H$_{2}$O)$_{n}$ clusters. In about half of the cases the geometrical substructure of the water molecules in the graphite-(H$_{2}$O)$_{n}$ global minimum coincides with that of the corresponding free water cluster. Exceptions occur when the interaction with graphite induces a change in geometry. A comparison of our results with available theoretical and experimental data is performed.

description: Area under the ROC curve (AUC) optimisation techniques developed for neural networks have recently demonstrated their capabilities in different audio and speech related tasks. However, due to its intrinsic nature, AUC optimisation has focused only on binary tasks so far. In this paper, we introduce an extension to the AUC optimisation framework so that it can be easily applied to an arbitrary number of classes, aiming to overcome the issues derived from training data limitations in deep learning solutions. Building upon the multiclass definitions of the AUC metric found in the literature, we define two new training objectives using a one-versus-one and a one-versus-rest approach. In order to demonstrate its potential, we apply them in an audio segmentation task with limited training data that aims to differentiate 3 classes: foreground music, background music and no music. Experimental results show that our proposal can improve the performance of audio segmentation systems significantly compared to traditional training criteria such as cross entropy.
Child Drawing Development Optimization Algorithm based on Child's Cognitive Development

description: This paper proposes a novel metaheuristic Child Drawing Development Optimization (CDDO) algorithm inspired by the child's learning behaviour and cognitive development using the golden ratio to optimize the beauty behind their art. The golden ratio was first introduced by the famous mathematician Fibonacci. The ratio of two consecutive numbers in the Fibonacci sequence is similar, and it is called the golden ratio, which is prevalent in nature, art, architecture, and design. CDDO uses golden ratio and mimics cognitive learning and child's drawing development stages starting from the scribbling stage to the advanced pattern-based stage. Hand pressure width, length and golden ratio of the child's drawing are tuned to attain better results. This helps children with evolving, improving their intelligence and collectively achieving shared goals. CDDO shows superior performance in finding the global optimum solution for the optimization problems tested by 19 benchmark functions. Its results are evaluated against more than one state of art algorithms such as PSO, DE, WOA, GSA, and FEP. The performance of the CDDO is assessed, and the test result shows that CDDO is relatively competitive through scoring 2.8 ranks. This displays that the CDDO is outstandingly robust in exploring a new solution. Also, it reveals the competency of the algorithm to evade local minima as it covers promising regions extensively within the design space and exploits the best solution.

Numerical estimates of the attempt frequency are analyzed in comparison with theoretical predictions from the Fokker-Planck equation for the Neel-Brown model. It is found that for a nanomagnet with the thin-film geometry, theoretically predicted values for the universal case are in excellent agreement with numerical estimates.

description: In this article, we describe some of the difficulties some parents and therapists can encounter when faced with child to parent violence. We hope to show that an adapted Non Violent Resistance Programme seems to restore confidence and competence to parents who have lived with child to parent violence; the Non Violent Resistance programme also provides therapists with a helpful way to talk with parents about their experiences of violence. Such conversations  can lead to an end of the fear and isolation at the heart of the experience. We will also outline an innovative research project involving five countries in the European Union that includes, as its objectives, increasing awareness of child to parent violence and exploring participants responses to a two day training programme on Non Violent Resistance. As a way of reflecting on experience and practice, we will also use an anonymised case example, drawn from the experiences of one of us.

These samples are dominated by disk stars, and we use them to constrain the shape of the main-sequence photometric parallax relation M_r(r-i) and to study the properties of wide binary systems. We estimate M_r(r-i) by searching for a relation that minimizes the difference between distance moduli of primary and secondary components of wide binary candidates. We model M_r(r-i) by a fourth degree polynomial and determine the coefficients using Markov Chain Monte Carlo fitting, independently for each sample. Aided by the derived photometric parallax relation, we construct a series of high-quality catalogs of candidate main-sequence binary stars. Using these catalogs, we study the distribution of semi-major axes of wide binaries, a, in the 2,000 < a < 47,000 AU range. We find the observations to be well described by the Opik distribution, f(a)~1/a, for a

description: The solution of the eigenvalue problem of the Laplacian on a general homogeneous space G/H is given. Here, G is a compact, semisimple Lie group, H is a closed subgroup of G, and the rank of H is equal to the rank of G. It is shown that the multiplicity of the lowest eigenvalue of the Laplacian on G/H is just the degeneracy of the lowest Landau level for a particle moving on G/H in the presence of the background gauge field. Moreover, the eigenspace of the lowest eigenvalue of the Laplacian on G/H is, up to a sign, equal to the G-equivariant index of the Dirac operator of Kostant on G/H.

Remarks.— Gripp (1927) and Vonderbank (1970) ascribed a variety of isolated appendages and venters to what they considered to be P. spitzbergica, but because there are two galatheoid species in the region, those cannot be ascribed to any taxon with certainty. None of those specimens were attached to carapaces. It is likely, however, that most, if not all, can be attributed to Valamunida haeggi Klompmaker and Robins sp. nov. because 15/16 carapaces studied are ascribed to this species and appendages are found in the same rock as some of the carapaces for the ones found in Zachariassendalen (NRM-PZ Ar68002, NRM-PZ Ar68003, NRM-PZ Ar68006, and NRM-PZ Ar68010/Ar68013).

description: We determine the stability, the geometry, the electronic and magnetic structure of hydrogen-terminated graphene-nanoribbons edges as a function of the hydrogen content of the environment by means of density functional theory. Antiferromagnetic zigzag ribbons are stable only at extremely-low ultra-vacuum pressures. Under more standard conditions, the most stable structures are the mono- and di-hydrogenated armchair edges and a zigzag edge reconstruction with one di- and two mono-hydrogenated sites. At high hydrogen-concentration ``bulk'' graphene is not stable and spontaneously breaks to form ribbons, in analogy to the spontaneous breaking of graphene into small-width nanoribbons observed experimentally in solution. The stability and the existence of exotic edge electronic-states and/or magnetism is rationalized in terms of simple concepts from organic chemistry (Clar's rule)

Subjects: subject: Astrophysics (astro-ph)

description: The correlation dimension, that is, the dimension obtained by computing the correlation function of pairs of points of a trajectory in phase space, is a numerical technique introduced in the field of nonlinear dynamics in order to compute the dimension of the manifold in which an orbit moves, without the need of knowing the actual equations of motion that give rise to the trajectory. This technique has been proposed in the past as a method to measure the dimension of stellar orbits in astronomical potentials, i.e., the number of isolating integrals of motion the orbits obey. Although the algorithm can in principle yield that number, some care has to be taken in order to obtain good results. We studied the relevant parameters of the technique, found their optimal values, and tested the validity of the method on a number of potentials previously studied in the literature, using the SALI, Lyapunov exponents and spectral dynamics as gauges.

Description.—Complete tooth shows translucent cap at apex. Both teeth small, ~ 1 mm and 2 mm; strongly posteriorly recurved and laterally compressed. Outer surfaces bear very fine longitudinal striations. Both teeth with expanded
area of spongy bone at base that marks jaw attachment. Vertebra small, similarly-sized to teeth.
Remarks.—The teleost material reported here represents the second finding of actinopterygian fish from the Cenozoic of Spitsbergen. The first actinopterygian was described as a fossil bowfin, Pseudamia heintzi, by Lehman (1951). According to Thomsen (2013), the specimen was discovered at Cap Dresselhuys, implying that it derives from the late Paleocene (Thanetian) Grumantbyen Formation (Dallmann 2015), which overlies the Basilika Formation. Both bowfin (Amia sp.) and scombroid teleost teeth assigned to Eutrichiurides have been described from the Eocene Eureka Sound Formation on Banks Island in the Canadian High Arctic by Gottfried and Eberle (2018). In addition to its presence in the High Arctic, scombroid teeth are known from many Paleogene localities in Europe, Africa, India, and the USA (Gottfried and Eberle 2018).

description: Introduction

A promising reparative therapy for Parkinson’s disease is the transplantation of dopaminergic neurons harvested from foetal tissue. However, this is limited by poor survival leading to poor striatal reinnervation and motor recovery. We have recently shown that GDNF-enriched hydrogels have the potential to improve these graft outcomes1,2, suggesting that this approach merits extension to other neurotrophic factors.  One potential neurotrophic factor to use in this context is growth differentiation factor 5 (GDF-5) which is a potent dopaminergic neuroprotective agent. Therefore, this study sought to determine the survival and efficacy of primary dopaminergic grafts in a GDF-5-loaded collagen hydrogel in a rat model of Parkinson's disease.

Methods:

Forty Sprague Dawley rats received a unilateral medial forebrain bundle 6-hydroxydopamine lesion two weeks before transplantation surgery. They then received an intrastriatal transplant of E14 ventral mesencephalic (VM) cells (300k/6µl) with or without encapsulation in a collagen hydrogel with or without enrichment with GDF-5 (20µg/6µl). Methamphetamine induced rotations were assessed as a measure of functional restoration, while immunohistochemistry for dopaminergic neurons (tyrosine hydroxylase), microglia (OX-42) and astrocytes (GFAP) was used to identify graft survival, reinnervation, and host immune response post mortem.

Approach for statistical analysis:

A randomised and blinded experimental approach was used throughout. All data were analysed using ANOVA (one-way or two-way with repeated measures where appropriate), with post hoc Bonferroni test as appropriate.

4. Results and conclusions:

Surprisingly, we found that incorporation of GDF-5, but not the collagen hydrogel, into the transplantation process actually reduced the survival, reinnervation and functional capacity of the VM transplants suggesting that the GDF-5 was toxic to the cells. In conclusion, this study suggests that GDF-5, at the dose used in the present study, is detrimental to VM grafts. Therefore, it was not possible to demine if the collagen hydrogel provided any beneficial effects.

description: There exist two canonical approaches to describe open quantum systems by a time-evolution equation: the Nakajima-Zwanzig quantum master equation, featuring a time-nonlocal memory kernel $\mathcal{K}$, and the time-convolutionless equation with a time-local generator $\mathcal{G}$. These key quantities have recently been shown to be connected by an exact fixed-point relation [Phys. Rev. X 11, 021041 (2021)]. Here we show that this implies a recursive relation between their perturbative expansions, allowing a series for the kernel $\mathcal{K}$ to be translated directly into a corresponding series for the more complicated generator $\mathcal{G}$. This leads to an elegant way of computing the generator using well-developed, standard memory-kernel techniques for strongly interacting open systems. Moreover, it allows for an unbiased comparison of time-local and time-nonlocal approaches independent of the particular technique chosen to calculate expansions of $\mathcal{K}$ and $\mathcal{G}$ (Nakajima-Zwanzig projections, real-time diagrams, etc.). We illustrate this for leading and next-to-leading order calculations of $\mathcal{K}$ and $\mathcal{G}$ for the single impurity Anderson model using both the bare expansion in the system-environment coupling and a more advanced renormalized series. We compare the different expansions obtained, quantify the legitimacy of the generated dynamics (complete positivity) and benchmark with the exact result in the non-interacting limit.

description: We derive analytic solutions of a chameleon scalar field $ϕ$ that couples to a non-relativistic matter in the weak gravitational background of a spherically symmetric body, paying particular attention to a field mass $m_A$ inside of the body. The standard thin-shell field profile is recovered by taking the limit $m_A*r_c \to \infty$, where $r_c$ is a radius of the body. We show the existence of "no-shell" solutions where the field is nearly frozen in the whole interior of the body, which does not necessarily correspond to the "zero-shell" limit of thin-shell solutions. In the no-shell case, under the condition $m_A*r_c \gg 1$, the effective coupling of $ϕ$ with matter takes the same asymptotic form as that in the thin-shell case. We study experimental bounds coming from the violation of equivalence principle as well as solar-system tests for a number of models including $f(R)$ gravity and find that the field is in either the thin-shell or the no-shell regime under such constraints, depending on the shape of scalar-field potentials. We also show that, for the consistency with local gravity constraints, the field at the center of the body needs to be extremely close to the value $ϕ_A$ at the extremum of an effective potential induced by the matter coupling.

description: We present observational constraints on the solar chromospheric heating contribution from acoustic waves with frequencies between 5 and 50 mHz. We utilize observations from the Dunn Solar Telescope in New Mexico complemented with observations from the Atacama Large Millimeter Array collected on 2017 April 23. The properties of the power spectra of the various quantities are derived from the spectral lines of Ca II 854.2 nm, H I 656.3 nm, and the millimeter continuum at 1.25 mm and 3 mm. At the observed frequencies the diagnostics almost all show a power law behavior, whose particulars (slope, peak and white noise floors) are correlated with the type of solar feature (internetwork, network, plage). In order to disentangle the vertical versus transverse plasma motions we examine two different fields of view; one near disk center and the other close to the limb. To infer the acoustic flux in the middle chromosphere, we compare our observations with synthetic observables from the time-dependent radiative hydrodynamic RADYN code. Our findings show that acoustic waves carry up to about 1 kW m$^{-2}$ of energy flux in the middle chromosphere, which is not enough to maintain the quiet chromosphere, contrary to previous publications.

description: Die Debatte um die Integration von autonomen Systemen in Streitkräfte wird oftmals auf einer (militär-)strategischen Ebene geführt. Die technisch-operativen Aspekte werden außerhalb des Fachpublikums häufig nur am Rande erwähnt. Der Beitrag analysiert die Integration von U(C)AVs in den operativen Flugzeugträgerbetrieb am Beispiel der X‑47B. Die Studie zeigt, dass es keine fundamentalen Probleme bei der Integration gibt, U(C)AVs in einem Fünf-Jahres-Horizont zur neuen maritimen Realität gehören und die Gefahr eines Rüstungswettlaufs in Bezug auf autonome Waffensysteme steigen wird.

description: The abundance evolution of interstellar dust species originating from stellar sources and from condensation in molecular clouds in the local interstellar medium of the Milky Way is studied and the input of dust material to the Solar System is determined. A one-zone chemical evolution model of the Milky Way for the elemental composition of the disk combined with an evolution model for its interstellar dust component similar to that of Dwek (1998) is developed. The dust model considers dust-mass return from AGB stars as calculated from synthetic AGB models combined with models for dust condensation in stellar outflows. Supernova dust formation is included in a simple parameterized form which is gauged by observed abundances of presolar dust grains with supernova origin. For dust growth in the ISM a simple method is developed for coupling this with disk and dust evolution models. The time evolution of the abundance of the following dust species is followed in the model: silicate, carbon, silicon carbide, and iron dust from AGB stars and from SNe as well as silicate, carbon, and iron dust grown in molecular clouds. It is shown that the interstellar dust population is dominated by dust accreted in molecular clouds; most of the dust material entering the Solar System at its formation does not show isotopic abundance anomalies of the refractory elements, i.e., inconspicuous isotopic abundances do not point to a Solar System origin of dust grains. The observed abundance ratios of presolar dust grains formed in SN ejecta and in AGB star outflows requires that for the ejecta from SNe the fraction of refractory elements condensed into dust is 0.15 for carbon dust and is quite small ($\sim10^{-4}$) for other dust species.

An experimental investigation of the wall-pressure field during turbulent incompressible pipe flow
Creators: name: Williams, Norman S.W.
Publisher: name: University of British Columbia
Year: 2010

description: An optical technique was developed to make possible a study of the instantaneous structure of the turbulent wall-pressure field. The approach involved the use of real-time laser-holographic-moiré interferometry. A moiré fringe pattern generated by the holographic method was superimposed on the surface of a specially-fabricated compliant pipe wall. The compliant surface, in response to wall-pressure changes, introduces optical path length changes which are manifested by distortions in the fringe field. The fringe distortions, observed during flow, were recorded (framed area, 11 mm x 34 mm) by means of medium-speed motion photography. The amplitude of fringe distortion provides a measure of the pressure magnitude at the wall. A 26.3 mm ID horizontal glass pipline (7.0 m long) supplied with distilled water from a constant head reservoir was used in the study. Photographs taken of the fringe patterns observed at a flow velocity (U) of 0.47 m/sec (Re[sub=d] = 12,300) were analysed. Results show that the wall-pressure field consists of a positive and negative pressure region. A statistical analysis reveals that the wall-pressure distribution is asymmetrical (Skewness = -0.29). From an analysis of the pressure patterns, a relationship between the generation of wall-pressure fluctuations and known wall-layer flow characteristics is inferred. A flow model is proposed to explain some aspects of the wall region dynamics and a mechanism for particle detachment from a wall, during turbulent flow, is also presented.

description: Magnetowave induced plasma wakefield acceleration (MPWA) in a relativistic astrophysical outflow has been proposed as a viable mechanism for the acceleration of cosmic particles to ultra high energies. Here we present simulation results that clearly demonstrate the viability of this mechanism for the first time. We invoke the high frequency and high speed whistler mode for the driving pulse. The plasma wakefield so induced validates precisely the theoretical prediction. We show that under appropriate conditions, the plasma wakefield maintains very high coherence and can sustain high-gradient acceleration over a macroscopic distance. Invoking gamma ray burst (GRB) as the source, we show that MPWA production of ultra high energy cosmic rays (UHECR) beyond ZeV 10^21 eV is possible.

description: There is significant interest in potential experimental tests of macroscopic quantum effects, both to test potential modifications to quantum theory and to probe the quantum nature of gravity. A proposed platform with which to generate the required macroscopic quantum spatial superposition is a nanodiamond containing a negatively charged nitrogen vacancy (${\text{NV}}^{-}$) centre. In this review, methods to fabricate nanodiamonds containing ${\text{NV}}^{-}$ suitable for these quantum applications are discussed. The proposed probes of the macroscopic limits of quantum theory are presented along with the spin physics of the ${\text{NV}}^{-}$ centre relevant to those tests.

description: If $h$ is a nondecreasing real valued function and $0\leq q\leq 2$, we analyse the boundary behaviour of the gradient of any solution $u$ of $-Δu+h(u)+\abs {\nabla u}^q=f$ in a smooth N-dimensional domain $Ω$ with the condition that $u$ tends to infinity when $x$ tends to $\partialΩ$. We give precise expressions of the blow-up which, in particular, point out the fact that the phenomenon occurs essentially in the normal direction to $\partialΩ$. Motivated by the blow--up argument in our proof, we also give in Appendix a symmetry result for some related problems in the half space.

description: We compute electron-phonon coupling (EPC) of selected phonon modes in graphene and graphite using various ab-initio methods. The inclusion of non-local exchange-correlation effects within the GW approach strongly renormalizes the square EPC of the A$'_1$ {\bf K} mode by almost 80$%$ with respect to density functional theory in the LDA and GGA approximations. Within GW, the phonon slope of the A$'_1$ {\bf K} mode is almost two times larger than in GGA and LDA, in agreement with phonon dispersions from inelastic x-ray scattering and Raman spectroscopy. The hybrid B3LYP functional overestimates the EPC at {\bf K} by about 30%. Within the Hartree-Fock approximation, the graphene structure displays an instability under a distortion following the A$'_1$ phonon at {\bf K}.
