description: To optimize fruit production, a portion of the flowers and fruitlets of apple trees must be removed early in the growing season. The proportion to be removed is determined by the bloom intensity, i.e., the number of flowers present in the orchard. Several automated computer vision systems have been proposed to estimate bloom intensity, but their overall performance is still far from satisfactory even in relatively controlled environments. With the goal of devising a technique for flower identification which is robust to clutter and to changes in illumination, this paper presents a method in which a pre-trained convolutional neural network is fine-tuned to become specially sensitive to flowers. Experimental results on a challenging dataset demonstrate that our method significantly outperforms three approaches that represent the state of the art in flower detection, with recall and precision rates higher than $90\%$. Moreover, a performance assessment on three additional datasets previously unseen by the network, which consist of different flower species and were acquired under different conditions, reveals that the proposed method highly surpasses baseline approaches in terms of generalization capability.

description: We present a theoretical analysis of signals for CPT and Lorentz violation in g-2 and charge-to-mass-ratio experiments on electrons and positrons in Penning traps. Experiments measuring anomaly frequencies are found to be the most sensitive to CPT violation. We find that the conventional figure of merit for CPT breaking, involving the difference of the electron and positron g factors, is inappropriate in this context, and an alternative is introduced. Bounds of approximately one part in 10^{20} are attainable.

description: Suspended particles can alter the properties of fluids and in particular also affect the transition from laminar to turbulent flow. In the present experimental study, we investigate the impact of neutrally buoyant, spherical inertial particles on transition to turbulence in a pipe flow. At low particle concentrations, like in single phase Newtonian fluids, turbulence only sets in when triggered by sufficiently large perturbations and, as characteristic for this transition localized turbulent regions (puffs) co-exist with laminar flow. In agreement with earlier studies this transition point initially moves to lower Reynolds number (Re) as the particle concentration increases. At higher concentrations however the nature of the transition qualitatively changes: Laminar flow gives way to a globally fluctuating state following a continuous, non-hysteretic transition. A further increase in Re results in a secondary instability where localized puff-like structures arise on top of the uniformly fluctuating background flow. At even higher concentration only the uniformly fluctuating flow is found and signatures of Newtonian type turbulence are no longer observed.

description: Differential cross sections for dijet photoproduction in association with a leading neutron using the reaction e^+ + p --> e^+ + n + jet + jet + X_r have been measured with the ZEUS detector at HERA using an integrated luminosity of 6.4 pb^{-1}. The fraction of dijet events with a leading neutron in the final state was studied as a function of the jet kinematic variables. The cross sections were measured for jet transverse energies E^{jet}_T > 6 GeV, neutron energy E_n > 400 GeV, and neutron production angle theta_n < 0.8 mrad. The data are broadly consistent with factorization of the lepton and hadron vertices and with a simple one-pion-exchange model.

description: Critical properties of the Calogero-Sutherland model of $BC_N$-type ($BC_N$-CS model) are studied. Using the asymptotic Bethe-ansatz spectrum of the $BC_N$-CS model, we calculate finite-size corrections in the energy spectrum. Since the $BC_N$-CS model does not possess translational invariance, the finite-size spectrum acquires the contributions coming from ``boundaries''. We show that the low-energy critical behavior of the model is described by $c=1$ boundary conformal field theory. Thus the universality class of the model is identified as a chiral Tomonaga-Luttinger liquid.

description: The number of Ultra-Diffuse Galaxies (UDGs) in clusters is of significant importance to constrain models of their formation and evolution. Furthermore, their distribution inside clusters may tell us something about their interactions with their environments. In this work we revisit the abundance of UDGs in a more consistent way than in previous studies. We add new data of UDGs in eight clusters from the Kapteyn IAC WEAVE INT Clusters Survey (KIWICS), covering a mass range in which only a few clusters have been studied before, and complement these with a compilation of works in the literature to homogeneously study the relation between the number of UDGs and the mass of their host cluster. Overall, we find that the slope of the number of UDGs$-$cluster mass relation is consistent with being sublinear when considering galaxy groups or linear if they are excluded, but we argue that most likely the behavior is sublinear. When systematically studying the relation between the projected distance to the innermost UDG and M$_{200}$ for each cluster, we find hints that favor a picture in which massive clusters destroy UDGs in their centres.

 Material examined. None, only known from type holotype, which was lost (Vilela et al. 2019), originally housed at RBINS.
 Known distribution. Brazil (Southern Minas Gerais state).
 Diagnosis and remarks. Described from a single male collected in Caxambu, Minas Gerais state, this species has not been collected again, despite some search in that area by A.B.M. Machado (pers. comm. in 2019). Because of this, the assessment of H. obsoletum in the IUCN Red List is Data Deficient (Vilela & Guillermo-Ferreira 2021i). According to Selys (1886), this species can be separated from the other congeners by the broad shape of the MP plate, which has a rounded apex. Vilela et al. (2019b) made a thorough analysis of this enigmatic species, separating it from H. denisye and other congeners.

description: Educational literature regarding school communication takes a very different approach than the Communication literature. Education scholars employ a view of communication processes that reflect a linear information-transmission conceptualization of communication processes, rather than the contemporary approach of communication scholars, who treat communication processes as nonlinear, relational, and constitutive of meaning. This thesis includes the findings from a study in which 43 parents completed a survey, 19 of whom were also interviewed about their perceptions and satisfaction with school communication. The interviews were recorded, transcribed and analyzed for recurring trends and themes. Open-ended communicative experience survey responses were combined with interview quotes to provide one dataset. The surveys and transcripts were thematically analyzed, resulting in 14 themes. Although parental satisfaction with general school communication registered slightly higher than that with child-specific communication, findings suggest that parental satisfaction with school communication is heavily dependent on individual teachers. Overall, participants expressed the desire to communicate with schools while they feel schools communicate to them. Parents also report that they feel school communication is ineffective overall and must be initiated by the parent. It is interesting to note that parents’ perception of schools communicating “to” rather than “with” closely reflects the schools literature’s treatment of communication. This important finding highlights the need for schools and parents to be aware of parental perceptions of school communication to better meet both parties’ needs. Limitations and strengths of the study and recommendations for future research and application are discussed.

Mass-transfer properties of overcontact systems in the Kepler eclipsing binary catalog
Creators: name: Kouzuma, Shinjirou
Publisher: name: arXiv
Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We selected mass-transferring binary candidates from the catalog of Kepler eclipsing binary stars and investigated the dependence of the mass-transfer rate on several astrophysical quantities, including orbital period, semi-major axis, mass ratio, fill-out factor, temperature, and mass. We selected these candidates using $O-C$ diagrams and calculated their mass-transfer rates. Primary masses were obtained from the mass--temperature relation, and the temperatures of the component stars were extracted from a catalog of temperatures for Kepler eclipsing binary stars. The mass-transfer rates of overcontact systems have associations with astrophysical quantities that seem to differ from those of semi-detached or detached systems. These associations indicate that mass exchange from more- to less-massive components (from less- to more-massive components) generally becomes rapid (slow) as the mass exchange evolves. However, for mass exchange from more- to less-massive components, this tendency is not reasonable for binaries with a short period ($P<0.4$ d) and low mass ($M_1<1.2$ M$_\odot$) because the correlations of these binaries are opposite to those of binaries with long period and high mass. These different correlations likely arise from differences in correlation between subtypes of W UMa systems (i.e., W- and A-types). Alternatively, when mass exchange from more- to less-massive components reoccurs after a mass-ratio reversal, its properties may differ from those of the first mass exchange.

 Material examined. None.
 Known distribution. Brazil (Nova Friburgo, Rio de Janeiro state).
 Diagnosis and remarks. Regarding H. ochraceum, it was described by Selys (1862) based on the two sexes, including one male and two females (one of them teneral). According to Williamson (1919), Hagen considered H. cinnamomeum to be a junior synonym of H. ochraceum, though not formalizing this proposition. Additionally, one can observe many similarities between the female assigned as H. ochraceum (depicted by Williamson 1919, Plate IV fig. 19) and the female assigned as H. aurantiacum (Lencioni 2013, fig. 50b). The main problem is that the type specimens are now incomplete (the male is missing) and impossible to associate with any valid name (von Ellenrieder & Garrison 2007). However, as we have not studied the types in person, for now we do not consider this name as nomen dubium. Currently, there is not enough taxonomic information on this species to formalize a proper diagnosis. See further discussion under H. cinnamomeum.

gamma gamma -> gamma gamma as a Test of Weak Scale Quantum Gravity at the NLC
Creators: name: Davoudiasl, Hooman
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Recently, it has been proposed that the fundamental scale of quantum gravity can be close to the weak scale if there are large extra dimensions. This proposal has important phenomenological implications for processes at the TeV scale. We study the process gamma gamma -> gamma gamma, assuming an ultraviolet cutoff M_S \sim 1 TeV for the effective gravity theory. We find that, at center of mass energies \sqrt(s) \sim 1 TeV, the contribution of gravitationally mediated scattering to the cross section is comparable to that coming from the one-loop Feynman diagrams of the Standard Model. We thus conclude that the effects of weak scale quantum gravity can be studied at the Next Linear Collider (NLC), in the photon collider mode. Our results suggest that, for typical proposed NLC energies and luminosities, the range 1 TeV \lsim M_S \lsim 10 TeV can be probed.

description: It was recently shown that Strong Cosmic Censorship may be violated in highly charged black-hole spacetimes living in a universe with a positive cosmological constant. Several follow-up works have since suggested that such result, while conceptually interesting, cannot be upheld in practice. We focus here on the claim that the presence of charged massive scalars suffices to save Strong Cosmic Censorship. To the contrary, we show that there still exists a finite region in parameter space where Strong Cosmic Censorship is expected to be violated.

description: We establish the best possible approximation to a perfect quantum cloning machine which produces two clones out of a single input. We analyze both universal and state-dependent cloners. The maximal fidelity of cloning is shown to be 5/6 for universal cloners. It can be achieved either by a special unitary evolution or by a novel teleportation scheme. We construct the optimal state-dependent cloners operating on any prescribed two non-orthogonal states, discuss their fidelities and the use of auxiliary physical resources in the process of cloning. The optimal universal cloners permit us to derive a new upper bound on the quantum capacity of the depolarizing quantum channel.

description: Quantum communication between distant parties is based on suitable instances of shared entanglement. For efficiency reasons, in an anticipated quantum network beyond point-to-point communication, it is preferable that many parties can communicate simultaneously over the underlying infrastructure; however, bottlenecks in the network may cause delays. Sharing of multi-partite entangled states between parties offers a solution, allowing for parallel quantum communication. Specifically for the two-pair problem, the butterfly network provides the first instance of such an advantage in a bottleneck scenario. In this paper, we propose a more general method for establishing EPR pairs in arbitrary networks. The main difference from standard repeater network approaches is that we use a graph state instead of maximally entangled pairs to achieve long-distance simultaneous communication. We demonstrate how graph-theoretic tools, and specifically local complementation, help decrease the number of required measurements compared to usual methods applied in repeater schemes. We examine other examples of network architectures, where deploying local complementation techniques provides an advantage. We finally consider the problem of extracting graph states for quantum communication via local Clifford operations and Pauli measurements, and discuss that while the general problem is known to be NP-complete, interestingly, for specific classes of structured resources, polynomial time algorithms can be identified.

We also provide some numerical details of the computation of the bulk viscosity close to the Mott transition line, where the dissipation is dominated by decays of mesons into quarks and their inverse processes. We close with a summary of our current understanding of this quantity, which stresses the importance of loop resummation for obtaining the qualitatively correct result near the Mott line.

description: Effective scholarly research depends on collecting and linking accurate data about the varied components and outputs. Persistent identifiers (PIDs) such as ORCID IDs, DOIs, or accession numbers offer a solution to pinpoint specific resources and link them. This makes it possible to foster reproducibility eg by ensuring publications contain links to specific reagents and data generated; it means we can gather data about impact of funding, and facility use, and can serve many other use cases in the research community. These user stories are at the heart of the FREYA project, a 3 year EC-funded project that is part of the European Open Science Cloud (EOSC), where we and others are collaborating to build on the persistent identifier infrastructure, assess emerging identifier types and foster their development and adoption. In this session Martin Fenner (DataCite) and I will introduce the concept of the PID Graph, and some of the emerging persistent identifiers. We will demonstrate how it is possible to connect scholarly entities associated with those new PIDs to other things using the PID Graph, combining practical examples with audience discussion about what is possible with a PID Graph and how to get involved.

description: Context. Pulsars scintillate. Dynamic spectra show brightness variation of pulsars in the time and frequency domain. Secondary spectra demonstrate the distribution of fluctuation power in the dynamic spectra. Aims. Dynamic spectra strongly depend on observational frequencies, but were often observed at frequencies lower than 1.5 GHz. Scintillation observations at higher frequencies help to constrain the turbulence feature of the interstellar medium over a wide frequency range and can detect the scintillations of more distant pulsars. Methods. Ten pulsars were observed at 2250 MHz (S-band) with the Jiamusi 66 m telescope to study their scintillations. Their dynamic spectra were first obtained, from which the decorrelation bandwidths and time scales of diffractive scintillation were then derived by autocorrelation. Secondary spectra were calculated by forming the Fourier power spectra of the dynamic spectra. Results. Most of the newly obtained dynamic spectra are at the highest frequency or have the longest time span of any published data for these pulsars. For PSRs B0540+23, B2324+60 and B2351+61, these were the first dynamic spectra ever reported. The frequencydependence of scintillation parameters indicates that the intervening medium can rarely be ideally turbulent with a Kolmogorov spectrum. The thin screen model worked well at S-band for the scintillation of PSR B1933+16. Parabolic arcs were detected in the secondary spectra of three pulsars, PSRs B0355+54, B0540+23 and B2154+40, all of which were asymmetrically distributed. The inverted arclets of PSR B0355+54 were seen to evolve along the main parabola within a continuous observing session of 12 hours, from which the angular velocity of the pulsar was estimated that was consistent with the measurement by very long baseline interferometry (VLBI).

description: The coronagraphic instrument (CGI) on the Wide-Field Infrared Survey Telescope (WFIRST) will demonstrate technologies and methods for high-contrast direct imaging and spectroscopy of exoplanet systems in reflected light, including polarimetry of circumstellar disks. The WFIRST management and CGI engineering and science investigation teams have developed requirements for the instrument, motivated by the objectives and technology development needs of potential future flagship exoplanet characterization missions such as the NASA Habitable Exoplanet Imaging Mission (HabEx) and the Large UV/Optical/IR Surveyor (LUVOIR). The requirements have been refined to support recommendations from the WFIRST Independent External Technical/Management/Cost Review (WIETR) that the WFIRST CGI be classified as a technology demonstration instrument instead of a science instrument. This paper provides a description of how the CGI requirements flow from the top of the overall WFIRST mission structure through the Level 2 requirements, where the focus here is on capturing the detailed context and rationales for the CGI Level 2 requirements. The WFIRST requirements flow starts with the top Program Level Requirements Appendix (PLRA), which contains both high-level mission objectives as well as the CGI-specific baseline technical and data requirements (BTR and BDR, respectively)... We also present the process and collaborative tools used in the L2 requirements development and management, including the collection and organization of science inputs, an open-source approach to managing the requirements database, and automating documentation. The tools created for the CGI L2 requirements have the potential to improve the design and planning of other projects, streamlining requirement management and maintenance. [Abstract Abbreviated]

 Material examined. 1♁ VENEZUELA, Bolivar state, El Pauji, 4.viii.1990, (1000m asl), R.W. Garrison leg., ABMM.
 Known distribution. Southeastern Venezuela.
 Diagnosis and remarks. This species possesses a tubercle or apophysis on the ventral BP portion, a feature that is shared only with H. triangulare and H. ictericum. De Marmels (1987) stated that H. pemon keys out to H. ictericum following Williamson’s key (1919), but no further morphological characters are provided to separate the two species. In fact, it is highlighted that “ H. pemon is probably restricted to the “Gran Sabana”, a highland plateau on which the famous “Tepuis” (table mountains) stand” (De Marmels 1987). DSV and FAAL have seen specimens of both species (not the types), and, apart from coloration characters, they seem to be identical in their morphology. At any rate, we are waiting for examination of the types and a molecular analysis to test the monophyly of these species.

description: q-oscillators are associated to the simplest non-commutative example of Hopf algebra and may be considered to be the basic building blocks for the symmetry algebras of completely integrable theories. They may also be interpreted as a special type of spectral nonlinearity, which may be generalized to a wider class of f-oscillator algebras. In the framework of this nonlinear interpretation, we discuss the structure of the stochastic process associated to q-deformation, the role of the q-oscillator as a spectrum-generating algebra for fast growing point spectrum, the deformation of fermion operators in solid-state models and the charge-dependent mass of excitations in f-deformed relativistic quantum fields.

description: This thesis explores the ways that Sport for Development and Peace Programs incorporate local community input in planning and implementation. Selecting two programs operating in the Cypriot conflict – DOVES Olympic Project and PeacePlayers International Cyprus – the thesis explores each program’s interactions with the local community to discover the extent of local community input and participation to communicate local needs. Through the constructivist paradigm, semi-structured interviews are used to collect the experiences of facilitators and participants of both programs. Analyzing the lived experiences and perceptions of community members familiar with the programs represent important data to better understand community participation and its value to programs doing intercommunal work in Cyprus.

description: This novel-in-stories follows a trio of Vietnamese American siblings and their friends and family living in the shadow of the most powerful city in the world, Washington, D.C. Spanning the decades between the 1980s and 2010, the stories weave around local events such as the fall of the Little Saigon neighborhood and the growth of the Eden Center strip mall, and illustrate the shifting tapestry of the D.C. metropolitan area’s Vietnamese American history. The characters find themselves confronting the specters of war, refugee assimilation, poverty, violence, crime, gangs, and all the hiccups that go along with these traumas while building lives from the shards of a homeland they carry within themselves. But as the characters grow, so do the distances from each other, sometimes in violent and surprising ways.

description: We study the effect of interactions on the zero-temperature a.c. conductivity of 2D Anderson insulator at low frequencies. We show that the enhancement of the real part of conductivity due to the Coulomb correlations in the occupation numbers of localized states results in the change of the sign of imaginary part within a certain frequency range. As a result, the propagation of a surface plasmon in a localized system becomes possible. We analize the dispersion law of the plasmon for the two cases: unscreened Coulomb interactions and the interactions screened by a gate electrode spaced by some distance from the electron plane.
