description: Low-albedo, hydrated objects dominate the list of the largest asteroids. These objects have varied spectral shapes in the 3-$μ$m region, where diagnostic absorptions due to volatile species are found. Dawn's visit to Ceres has extended the view shaped by ground-based observing, and shown that world to be a complex one, potentially still experiencing geological activity. We present 33 observations from 2.2-4.0 $μ$m of eight large (greater than 200 km diameter) asteroids from the C spectral complex, with spectra inconsistent with the hydrated minerals we see in meteorites. We characterize their absorption band characteristics via polynomial and Gaussian fits to test their spectral similarity to Ceres, the asteroid 24 Themis (thought to be covered in ice frost), and the asteroid 51 Nemausa (spectrally similar to the CM meteorites). We confirm most of the observations are inconsistent with what is seen in meteorites and require additional absorbers. We find clusters in band centers that correspond to Ceres- and Themis-like spectra, but no hiatus in the distribution suitable for use to simply distinguish between them. We also find a range of band centers in the spectra that approaches what is seen on Comet 67P. Finally, variation is seen between observations for some objects, with the variation on 324 Bamberga consistent with hemispheric-level difference in composition. Given the ubiquity of objects with 3-$μ$m spectra unlike what we see in meteorites, and the similarity of those spectra to the published spectra of Ceres and Themis, these objects appear much more to be archetypes than outliers.

description: We have investigated the electronic properties of a C_60 molecule in between carbon nanotube leads. This problem has been tackled within a quantum chemical treatment utilizing a density functional theory-based LCAO approach combined with the Landauer formalism. Owing to low-dimensionality, electron transport is very sensitive to the strength and geometry of interfacial bonds. Molecular contact between interfacial atoms and electrodes gives rise to a complex conductance dependence on the electron energy exhibiting spectral features of both the molecule and electrodes. These are attributed to the electronic structure of the C_60 molecule and to the local density of states of the leads, respectively.

description: The doubling of massless Dirac fermions on two-dimensional lattices is theoretically studied. It has been shown that the doubling of massless Dirac fermions on a lattice with broken chiral symmetry is topologically protected even when the Dirac cone is tilted. This is due to the generalized chiral symmetry defined for lattice systems, where such models can be generated by a deformation of the chiral-symmetric lattice models. The present paper shows for two-band lattice models that this is a general way to produce systems with the generalized chiral symmetry in that such systems can always be transformed back to a lattice model with the conventional chiral symmetry. We specifically show that the number of zero modes is an invariant of the transformation, leading to the topological protection à la Nielsen-Ninomiya of the doubling of tilted and massless Dirac fermions in two dimensions.

description: The Harris-Aharony criterion for a statistical model predicts, that if a specific heat exponent $α\ge 0$, then this model does not exhibit self-averaging. In two-dimensional percolation model the index $α=-{1/2}$. It means that, in accordance with the Harris-Aharony criterion, the model can exhibit self-averaging properties. We study numerically the relative variances $R_{M}$ and $R_χ$ for the probability $M$ of a site belongin to the "infinite" (maximum) cluster and the mean finite cluster size $χ$. It was shown, that two-dimensional site-bound percolation on the square lattice, where the bonds play the role of impurity and the sites play the role of the statistical ensemble, over which the averaging is performed, exhibits self-averaging properties.

It is shown that an initial sand pile, under a wind flow carrying sand, flattens and gets a shape recalling barchan dunes. An evolution law is proposed for the profile and the summit of the dune. The dune dynamics is shown to be shape invariant. The invariant shape, the ``dune function'' is isolated.

description: We construct a consistent quantum field theory of a free massless (pseudo)scalar field in 1+1-dimensional space-times free of infrared divergences. We show that a continuous symmetry of (pseudo)scalar field translations is spontaneously broken. Goldstone bosons appear as quanta of a free massless (pseudo)scalar field. We show that the main inequality between vacuum expectation values of certain operators which has been used for the derivation of the Mermin-Wagner-Hohenberg theorem is fulfilled in the quantum field theory of a free massless (pseudo)scalar field free of infrared divergences.

description: The ultra-faint dwarf galaxy Leo V has shown both photometric overdensities and kinematic members at large radii, along with a tentative kinematic gradient, suggesting that it may have undergone a close encounter with the Milky Way. We investigate these signs of disruption through a combination of i) high-precision photometry obtained with the Hubble Space Telescope (HST), ii) two epochs of stellar spectra obtained with the Hectochelle Spectrograph on the MMT, and iii) measurements from the Gaia mission. Using the HST data, we examine one of the reported stream-like overdensities at large radii, and conclude that it is not a true stellar stream, but instead a clump of foreground stars and background galaxies. Our spectroscopic analysis shows that one known member star is likely a binary, and challenges the membership status of three others, including two distant candidates that had formerly provided evidence for overall stellar mass loss. We also find evidence that the proposed kinematic gradient across Leo V might be due to small number statistics. We update the systemic proper motion of Leo V, finding $(μ_α\cosδ, μ_δ)= (0.009\pm0.560$, $-0.777\pm0.314)$ mas yr$^{-1}$, which is consistent with its reported orbit that did not put Leo V at risk of being disturbed by the Milky Way. These findings remove most of the observational clues that suggested Leo V was disrupting, however, we also find new plausible member stars, two of which are located >5 half-light radii from the main body. These stars require further investigation. Therefore, the nature of Leo V still remains an open question.

description: We propose a matrix model to describe a class of fractional quantum Hall (FQH) states for a system of (N_1+N_2) electrons with filling factor more general than in the Laughlin case. Our model, which is developed for FQH states with filling factor of the form ν_{k_1k_2}=\frac{k_1+k_2}{k_1k_2} (k_1 and k_2 odd integers), has a U(N_1)\times U(N_2) gauge invariance, assumes that FQH fluids are composed of coupled branches of the Laughlin type, and uses ideas borrowed from hierarchy scenarios. Interactions are carried, amongst others, by fields in the bi-fundamentals of the gauge group. They simultaneously play the role of a regulator, exactly as does the Polychronakos field. We build the vacuum configurations for FQH states with filling factors given by the series ν_{p_1p_2}=\frac{p_2}{p_1p_2-1}, p_1 and p_2 integers. Electrons are interpreted as a condensate of fractional D0-branes and the usual degeneracy of the fundamental state is shown to be lifted by the non-commutative geometry behaviour of the plane. The formalism is illustrated for the state at ν={2/5}.

description: According to Clifford Lynch, Coalition for Networked Information president, a problem in developing digital libraries is that scarce resources get burned up in too many small-scale local projects, which then wither away for lack of institutional support. One approach to solving it is to concentrate funding on a few large institutions that have the technical skills and institutional resources to manage major long-term projects of national scope. A second approach is to help small, inexperienced institutions do it right. In the early stages of a digitization project, choices must be made: how much emphasis to put on preservation and how much on access; whether to do photographically exact images or structurally marked-up, searchable ASCII text. The purpose of this article is two-fold: to convince the reader of the importance of knowing the digitization literature and to introduce some of the most important elements of that literature. The bibliography emphasizes issues that cut across all options. Sections are on general works, landmark digitization projects, choice, quality, longevity, integrity, access, SGML markup, and copyright.

description: Giant clams offer small holders throughout the Indo-Pacific with good prospects for commercial culture to satisfy their increasing dependence on the cash economy. Two species appear promising for an emerging village-based export industry in Solomon Islands. These species are Tridacna crocea, the preferred species for the aquarium market, and T. derasa, the species that has the best potential for the seafood market. In this paper, a bioeconomic model is used in a normative analysis to explore optimal-management strategies for village farmers producing these clams. The normative study provides a benchmark against which current practices can be evaluated.

過去には,ピアノ譜から隠れマルコフモデル(HMM)を用いてギター用に編曲されたタブ譜を生成するシステムが提案されていたが,楽譜から得られる旋律情報のみ用いた編曲を行っているため,主旋律と和音を同時に演奏するためのタブ譜生成には利用できない.

本研究では,リードシートを入力として,与えられた旋律情報とコードシンボルの情報に対してHMMと押弦制約を用いてソロギタータブ譜の自動生成を行うシステムを作成する.リードシートに含まれる主旋律と和音の情報から主旋律と和音を含んだ押弦候補を多数作成し,押弦候補にHMMと押弦制約に基づいて押弦候補を絞り込むことで,主旋律と和音を同時に演奏するためのタブ譜を作成できる.

評価実験では,システムを用いて生成されたタブ譜を評価するためのアンケートを実施した.生成したタブ譜を6つの項目について7段階で評価してもらった.各楽曲の押弦位置の適切さや選択された和音の適切さについて自由に回答してもらった.その結果,楽曲の調やコードシンボルの切り替わりの頻度,コード進行の単純さなどの要因が,生成されたタブ譜の演奏のしやすさに大きく関わっている事が分かった.

description: The technical and allocative efficiency of broadacre farmers in a southern region of Western Australia is investigated over a three-year period. Applying data envelopment analysis (DEA) and stochastic frontier analysis (SFA) reveals there is some inefficiency in each year, which decreases over time. The distributions of technical efficiency in each year are positively skewed toward higher efficiency levels, indicating a majority of farms produce close to their maximum technical efficiency. DEA and SFA produce similar efficiency rankings of farms yet DEA rankings are more stable. The relationships between farm-specific variables and the DEA and SFA efficiency scores are investigated. There is evidence that farmers benefit from using at least a small amount of tillage, rather than using ‘no-till’ practices. Education levels and farmer age are found to positively influence technical efficiency. Using a DEA profit efficiency model, the duality between the directional distance function and the profit function allows the decomposition of economic efficiency into its technical and allocative components. Greater gains in profitability are possible by improving allocative rather than technical efficiency. Technically efficient farms are not necessarily allocatively efficient. Also, Tobit regression results indicate that the variables associated with variation in technical efficiency are different to those explaining the variation in allocative efficiency.
Multiparticle quantum walk with a gas-like interaction

description: We analyze the dynamics of multiparticle discrete-time quantum walk on the two-dimensional lattice, with an interaction inspired on a classical model for gas collision, called HPP model. In this classical model, the direction of motion changes only when the particles collide head-on, preserving momentum and energy. In our quantum model, the dynamics is driven by the usual quantum-walk evolution operator if the particles are on different nodes, and is driven by the HPP rules if the particles are in the same node, linearly extended for superpositions. Using this new form of evolution operator, we numerically analyze three physical quantities for the two-walker case: The probability distribution of the position of one walker, the standard deviation of the position of one walker, and the entanglement between the walkers as a function of the number of steps. The numerical analysis implies that the entanglement between the walkers as a function of the number of steps initially increases and quickly tends to a constant value, which depends on the initial condition. We compare the results obtained using the HPP interaction with the equivalent ones using the phase interaction, which is based on an evolution operator that inverts the sign of the coin operator if the walkers are in the same position.

Design/methodology/approach – The method is fundamentally anthropological with strong consideration given to reports contemporary behaviors in law cases and news reports. Findings – The findings suggest that rights-holder organizations like the Recording Industry Association of America are learning how to apply technology more effectively to their policing efforts. This could significantly alter the risk of infringement. Originality/value – Technology has long been recognized as a key factor in enabling copyright infringement. Some new technologies attempt to restrict copying (e.g. Digital Rights Management software). Now internet software is being used systematically for discovery and policing.

Influence of quantum fluctuations on zero-temperature phase transitions between collinear and noncollinear states in frustrated spin systems

description: We study a square-lattice spin-half Heisenberg model where frustration is introduced by competing nearest-neighbor bonds of different signs. We discuss the influence of quantum fluctuations on the nature of the zero-temperature phase transitions from phases with collinear magnetic order at small frustration to phases with noncollinear spiral order at large frustration. We use the coupled cluster method (CCM) for high orders of approximation (up to LSUB6) and the exact diagonalization of finite systems (up to 32 sites) to calculate ground-state properties. The role of quantum fluctuations is examined by comparing the ferromagnetic-spiral and the antiferromagnetic-spiral transition within the same model. We find clear evidence that quantum fluctuations prefer collinear order and that they may favour a first order transition instead of a second order transition in case of no quantum fluctuations.

description: Collaborative research and development (R&D) activities involve researchers working closely with industry, community and/or other stakeholders to address research problems, as promoted by the Australian Cooperative Research Centre (CRC) Program. Case study analysis of two collaborative research activities undertaken by the CRC for Sustainable Sugar Production has identified some important positive and negative features of collaborative research. These findings and the results of a survey of CRC Sugar stakeholders will contribute to the development of a framework to systematically evaluate the performance of collaborative research activities. The proposed evaluation framework is expected to contribute knowledge regarding the value of collaborative research, as well as benefit researchers, stakeholders, funders, and research managers, and allow them to improve the efficiency and effectiveness of collaborative research activities.

description: Endoscopy is a routine imaging technique used for both diagnosis and minimally invasive surgical treatment. Artifacts such as motion blur, bubbles, specular reflections, floating objects and pixel saturation impede the visual interpretation and the automated analysis of endoscopy videos. Given the widespread use of endoscopy in different clinical applications, we contend that the robust and reliable identification of such artifacts and the automated restoration of corrupted video frames is a fundamental medical imaging problem. Existing state-of-the-art methods only deal with the detection and restoration of selected artifacts. However, typically endoscopy videos contain numerous artifacts which motivates to establish a comprehensive solution. We propose a fully automatic framework that can: 1) detect and classify six different primary artifacts, 2) provide a quality score for each frame and 3) restore mildly corrupted frames. To detect different artifacts our framework exploits fast multi-scale, single stage convolutional neural network detector. We introduce a quality metric to assess frame quality and predict image restoration success. Generative adversarial networks with carefully chosen regularization are finally used to restore corrupted frames. Our detector yields the highest mean average precision (mAP at 5% threshold) of 49.0 and the lowest computational time of 88 ms allowing for accurate real-time processing. Our restoration models for blind deblurring, saturation correction and inpainting demonstrate significant improvements over previous methods. On a set of 10 test videos we show that our approach preserves an average of 68.7% which is 25% more frames than that retained from the raw videos.

description: We describe non-equilibrium phase transitions in arrays of dynamical systems with cubic nonlinearity driven by multiplicative Gaussian white noise. Depending on the sign of the spatial coupling we observe transitions to ferromagnetic or antiferromagnetic ordered states. We discuss the phase diagram, the order of the transitions, and the critical behaviour. For global coupling we show analytically that the critical exponent of the magnetization exhibits a transition from the value 1/2 to a non-universal behaviour depending on the ratio of noise strength to the magnitude of the spatial coupling.

description: Abstract: Active systems such as microorganisms and self-propelled particles show a plethora of collective phenomena, including swarming, clustering, and phase separation. Control over the propulsion direction and switchability of the interactions between the individual self-propelled units may open new avenues in designing of materials from within. Here, we present a self-propelled particle system, consisting of half-gold-coated titania (TiO2) particles, in which we can quickly and on-demand reverse the propulsion direction, by exploiting the different photocatalytic activities on both sides. We demonstrate that the reversal in propulsion direction changes the nature of the hydrodynamic interaction from attractive to repulsive and can drive the particle assemblies to undergo both fusion and fission transitions. Moreover, we show these active colloids can act as nucleation sites, and switch rapidly the interactions between active and passive particles, leading to reconfigurable assembly and disassembly. Our experiments are qualitatively described by a minimal hydrodynamic model.

description: Abstract: Constipation is a common but not a universal feature in early PD, suggesting that gut involvement is heterogeneous and may be part of a distinct PD subtype with prognostic implications. We analysed data from the Parkinson’s Incidence Cohorts Collaboration, composed of incident community-based cohorts of PD patients assessed longitudinally over 8 years. Constipation was assessed with the MDS-UPDRS constipation item or a comparable categorical scale. Primary PD outcomes of interest were dementia, postural instability and death. PD patients were stratified according to constipation severity at diagnosis: none (n = 313, 67.3%), minor (n = 97, 20.9%) and major (n = 55, 11.8%). Clinical progression to all three outcomes was more rapid in those with more severe constipation at baseline (Kaplan–Meier survival analysis). Cox regression analysis, adjusting for relevant confounders, confirmed a significant relationship between constipation severity and progression to dementia, but not postural instability or death. Early constipation may predict an accelerated progression of neurodegenerative pathology.

description: We present a new algorithm to decide finiteness of matrix groups defined over a field of positive characteristic. Together with previous work for groups in zero characteristic, this provides the first complete solution of the finiteness problem for finitely generated matrix groups over an arbitrary field. We also give an algorithm to compute the order of a finite matrix group over a function field of positive characteristic. Our MAGMA implementations of these algorithms are publicly available.

 KRÖBER,, O. (1932): Zwei neue Dipteren aus Palästina. - Stettiner Entomologische Zeitung 93: 302; Stettin.
Die Art wurde nach einem Männchen aus „Reboboth“ [= Rehoboth] beschrieben. Das Material erhielt Kröber (laut Originalbeschreibung) von Erwin Lindner, im Stuttgarter Museum ist die Art nicht vorhanden (Tschorsnig in litt.). Es ist also davon auszugehen, dass Kröber den Holotypus behielt und dieser mit seiner Sammlung zerstört wurde.
 Die zur Charakterisierung von Dalmannia aharoniiaharonii in der kurzen Beschreibung genannten Merkmale liegen innerhalb der Variationsbreite von Dalmannia marginata. Aus Israel liegen Amnon Freidberg 15 Exemplare von Dalmannia marginatamarginata vor, die zwei vom Autor untersuchten Exemplare aus dieser Serie unterscheiden sich nicht von mitteleuropäischen Tieren von Dalmannia marginata. Dalmannia aharonii KRÖBER,, 1932 wird daher als jüngeres Synonym zu Dalmannia marginata (MEIGEN, 1824) gestellt [syn. n.].

description: Abstract: Quality, traceability and reproducibility are crucial factors in the reliable manufacture of cellular therapeutics, as part of the overall framework of Good Manufacturing Practice (GMP). As more and more cellular therapeutics progress towards the clinic and research protocols are adapted to comply with GMP standards, guidelines for safe and efficient adaptation have become increasingly relevant. In this paper, we describe the process analysis of megakaryocyte manufacture from induced pluripotent stem cells with a view to manufacturing in vitro platelets to European GMP for transfusion. This process analysis has allowed us an overview of the entire manufacturing process, enabling us to pinpoint the cause and severity of critical risks. Risk mitigations were then proposed for each risk, designed to be GMP compliant. These mitigations will be key in advancing this iPS-derived therapy towards the clinic and have broad applicability to other iPS-derived cellular therapeutics, many of which are currently advancing towards GMP-compliance. Taking these factors into account during protocol design could potentially save time and money, expediting the advent of safe, novel therapeutics from stem cells.

description: Interlibrary lending and document delivery have become an integral part of the services that contemporary libraries offer. The copyright laws in most countries authorized this copying within reasonable limits, but tensions with publishers may be growing. For interlibrary services to remain effective, libraries must continue to lobby politicians to defend their legal basis. Libraries must also continue to work with publishers to address legitimate economic concerns. This paper looks at the legal basis for interlibrary services, particularly document delivery, in the US, Canadian, and German law.
