description: When an ideal (no bulk pinning) flat type-II superconducting disk is subjected to a perpendicular magnetic field H_a, the first vortex nucleates at the rim when H_a = H_0, the threshold field, and moves quickly to the center of the disk. As H_a increases above H_0, additional vortices join the others, and together they produce a domelike field distribution of radius b. In this paper I present analytic solutions for the resulting magnetic-field and sheet-current-density distributions. I show how these distributions vary as b increases with H_a, and I calculate the corresponding field-increasing magnetization.

description: O crescimento exponencial do uso das redes de computadores (na sua maior parte a Internet) vem, a cada dia que se passa, expondo algumas fragilidades na forma atual da sua arquitetura. Um dos pontos mais afetado, e consequentemente o mais perceptível ao usuário final é a segurança das informações e a performance. O fato do conjunto de protocolos que formam o TCP/IP (centro da atual arquitetura da Internet) trabalhar nomeando hosts é o que torna a Internet atual insegura e com limitações de performance, porque nesse modelo o que é “protegido” é o canal por onde a informação vai transitar, e não a informação diretamente e a orientação do processo de roteamento é sobre o host e não sobre o conteúdo. A arquitetura Named Data Networking (NDN) se apresenta como uma nova forma de conduzir a Internet, alterando o paradigma de comunicação expondo uma nova abordagem tendo como base o conteúdo, independentemente de sua localização. A proposta da arquitetura NDN não é nomear os hosts, e sim o dado que será requisitado e enviado. Com o dado nomeado, a comunicação será centrada ao conteúdo e não centrada em hosts. Seguindo essa premissa, a proposta de segurança na arquitetura NDN é de proteger o arquivo diretamente, desde quando ele sair do remetente até chegar ao destinatário, assim o destinatário poderá ter a certeza de que o dado chegado foi realmente o dado solicitado. Apesar da performance não ser um dos princípios da arquitetura, a inteligência aplicada ao plano de dados com os múltiplos nexthops sobre os dados nomeados associado ao sistema de cache e gerência de interesse e conteúdo, confere melhor performance na entrega de dados e também melhor resiliência a congestionamentos, face a atual arquitetura da Internet. O objetivo desse trabalho é apresentar a arquitetura NDN, seus aspectos e princípios de design e protocolos através de uma pesquisa exploratória com uma revisão bibliográfica e relacionar problemas de segurança e de performance em pesquisa exploratória na literatura, apresentar dois simuladores da arquitetura e demonstrar o seu funcionamento, contribuindo assim para o conhecimento dessa arquitetura, para que se tenha cada vez uma Internet melhor.

description: The detailed evaluation of solar cells typically involves a computationally intensive modelling approach. While the complexity of the optical analysis scales with the number of material layers, analytical solutions for the power conversion efficiency generally come with restrictive model assumptions. Here, an explicit equation is proposed for the filling-factor via the voltage at the maximum power point and which is free of parameter assumptions. The conversion efficiency can thus be calculated directly without numerical procedures. In addition, absorption matrices are introduced in the geometric optics regime to facilitate a multi-layer analysis under incoherent sunlight. The framework is then applied to study the harvesting efficiencies of a high-performing industrial solar cell, a siliconperovskite tandem system and of ideal multi-junction devices for four different climatic zones on Earth. By combining satellite-retrieved datasets, historical, global (hemispherical) solar spectra were therefore reconstructed at a 1-min temporal and 1-nm spectral resolution on latitude-tilted planes and for a 14-year period.

description: Commodity workstations with multiple GPUs have been built by engineers and scientists for real-time rendering applications. As a result, a high display resolution can be achieved by connecting each GPU to a display monitor (resulting in a tiled large display). Using a multi-GPU workstation may not always produce a highly interactive rendering rate due to imbalanced rendering workloads among GPUs. In this work, we propose a parallel load balancing algorithm based on a screen partitioning strategy to dynamically balance the amount of vertices and triangles rendered by each GPU. Each GPU renders a screen region whose size may be different from the screen regions of other GPUs, but the amounts of vertices and triangles in those screen regions are balanced. It is possible that a screen region rendered by a GPU has to be displayed by another GPU. We propose a frame exchanging algorithm that allows GPUs to exchange screen regions efficiently. The inter-GPU communication overhead is very small since the data transferred between GPUs are a small amount of image pixels.

description: We present a detailed investigation of the magnetic properties of complex vanadium phosphates M(VO)2(PO4)2 (M = Ca, Sr) by means of magnetization, specific heat, 31P NMR measurements, and band structure calculations. Experimental data evidence the presence of ferro- and antiferromagnetic interactions in M(VO)2(PO4)2 resulting in a nearly vanishing Curie-Weiss temperature θ_{CW} < 1 K that contrasts with the maximum of magnetic susceptibility at 3 K. Specific heat and NMR measurements also reveal weak exchange couplings with the thermodynamic energy scale J_c = 10-15 K. Additionally, the reduced maximum of the magnetic specific heat indicates strong frustration of the spin system. Band structure calculations show that the spin systems of the M(VO)2(PO4)2 compounds are essentially three-dimensional with the frustration caused by competing ferro- and antiferromagnetic interactions. Both calcium and strontium compounds undergo antiferromagnetic long-range ordering at T_N = 1.5 K and 1.9 K, respectively. The spin model reveals an unusual example of controllable frustration in three-dimensional magnetic systems.

description: In a recent work the Green's functions of the $\mathcal{PT}$-symmetric scalar theory $g ϕ^{2}(iϕ)^ε$ were calculated at the first order of the logarithmic expansion, i.e. at first order in $ε$, and it was proposed to use this expansion in powers of $ε$ to implement a systematic renormalization of the theory. Using techniques that we recently developed for the analysis of an ordinary (hermitian) scalar theory, in the present work we calculate the Green's functions at $O(ε^2)$, pushing also the analysis to higher orders. We find that, at each finite order in $ε$, the theory is non-interacting for any dimension $d \geq 2$. We then conclude that by no means this expansion can be used for a systematic renormalization of the theory. We are then lead to consider resummations, and we start with the leading contributions. Unfortunately, the results are quite poor. Specifying to the physically relevant $i g ϕ^3$ model, we show that this resummation simply gives the trivial lowest order results of the weak-coupling expansion. We successively resum subleading diagrams, but again the results are rather poor. All this casts serious doubts on the possibility of studying the theory $g ϕ^{2}(iϕ)^ε$ with the help of such an expansion. We finally add that the findings presented in this work were obtained by us some time ago (December 2019), and we are delighted to see that these results, that we communicated to C.M. Bender in December 2019, are confirmed in a recent preprint (e-Print:2103.07577) of C.M. Bender and collaborators.

description: In recent years, the application of molybdenum oxide (MoOx) in a hole selective contact for siliconbased solar cells has been explored, because of its superior optical transmittance compared to doped Si-based passivating contacts. So far, its development has been hampered by the lack of thermal stability after a thermal treatment, at standard SHJ annealing conditions, is performed. Here, we present a MoOx contact combined with an ultra-thin AlOx interface passivation layer, that can sustain an annealing temperature of at least 210 0C which makes this structure industrially appealing for high-efficiency Si solar cells. Furthermore, to demonstrate this new MoOxbased passivating hole contact, a 6 inch hybrid solar cell with a n-type polysilicon (poly-Si(n+)) electron selective contact was made using pilot deposition tools, which resulted in an efficiency of 18.2 % with an open circuit voltage (Voc) of 651 mV, a fill factor (FF) of 75.6 %, and a short circuit current (Jsc) of 36.9 mA/cm2.

However, few irregular galaxies have observed magnetic field structures. Using the VLA, the GBT, and the ATCA, we have observed several irregular galaxies in the radio continuum to determine their magnetic field structures. Here we report on our results for the galaxies NGC 4214 and NGC 1569.

Size effects in the nonlinear resistance and flux creep in a virtual Berezinskii-Kosterlitz-Thouless state of superconducting films

description: We show that the size effects radically affect the electric field-current ($E-I$) relation of superconducting films. We calculate $E(J)$ due to thermally-activated hopping of single vortices driven by current $I$ across the film in a magnetic field $H$, taking into account interaction of free vortices with their antivortex images and peaks in the Meissner currents at the film edges. Unbinding of virtual vortex-antivortex pairs not only mimics the transport uniform BKT behavior, it can dominate the observed $E(J)$ and result in the field-dependent ohmic resistance at small $I$. We show that $E(I)$ can be tuned by changing the film geometry and propose experimental tests of this theory.

description: We have searched for IR emission from the intracluster dust (ICD) in the galaxy cluster A2029. Weak signals of enhanced extended emission in the cluster are detected at both 24 and 70 micron. However, the signals are indistinguishable from the foreground fluctuations. The 24 versus 70 micron color map does not discriminate the dust emission in the cluster from the cirrus emission. After excluding the contamination from the point sources, we obtain upper limits for the extended ICD emission in A2029, 5 x 10^3 Jy/sr at 24 micron and 5 x 10^4 Jy/sr at 70 micron. The upper limits are generally consistent with the expectation from theoretical calculations and support a dust deficiency in the cluster compared to the ISM in our galaxy. Our results suggest that even with the much improved sensitivity of current IR telescopes, a clear detection of the IR emission from ICD may be difficult due to cirrus noise.

description: Floating photovoltaic (FPV) installations are increasingly preferred in areas where land is scarce. This paper analyzes data for overwater and land-based sites in the high-temperature, high-humidity equatorial tropical climate of Singapore (SG) in comparison with the environments of Colorado (CO) and Florida (FL) in the United States. We first determine and compare metrics including the fraction of operating time during which the modules experience dew and rain. Using a data-based model, we compare the annual coulombs transferred for a module type under system voltage potential in the environments under study. We find that the FPV modules in the SG environment exhibit 50%–75% greater annual coulomb transfer than in the Florida environment, principally because of the uniformly hotter climate of SG compared to FL, which is seasonal. We discuss the results in view of the stress test levels in the potential-induced degradation (PID) test protocol of IEC TS 62804-1, which used the FL environment as the reference. Based on acceleration factor data for current transfer, we estimate that the following test conditions—85°C, 85% relative humidity, 96 h, with module nameplate system voltage applied contained in IEC TS 62804-1—are sufficient to screen for PID-shunting in crystalline-silicon modules being designed for FPV applications such as lakes and reservoirs in tropical environments.

description: We put forward a method that allows the experimental determination of the entire spatial mode spectrum of any arbitrary monochromatic wave field in a plane normal to its propagation direction. For coherent optical fields, our spatial spectrum analyzer can be implemented with a small number of benchmark refractive elements embedded in a single Mach-Zehnder interferometer. We detail an efficient setup for measuring in the Hermite-Gaussian mode basis. Our scheme should also be feasible in the context of atom optics for analyzing the spatial profiles of macroscopic matter waves.

description: The heterostructure consisting of the Mott insulator LaVO$_3$ and the band insulator SrTiO$_3$ is considered a promising candidate for future photovoltaic applications. Not only does the (direct) excitation gap of LaVO$_3$ match well the solar spectrum, but its correlated nature and predicted built-in potential, owing to the non-polar/polar interface when integrated with SrTiO$_3$, also offer remarkable advantages over conventional solar cells. However, experimental data beyond the observation of a thickness-dependent metal-insulator transition is scarce and a profound, microscopic understanding of the electronic properties is still lacking. By means of soft and hard X-ray photoemission spectroscopy as well as resistivity and Hall effect measurements we study the electrical properties, band bending, and band alignment of LaVO$_3$/SrTiO$_3$ heterostructures. We find a critical LaVO$_3$ thickness of five unit cells, confinement of the conducting electrons to exclusively Ti 3$d$ states at the interface, and a potential gradient in the film. From these findings we conclude on electronic reconstruction as the driving mechanism for the formation of the metallic interface in LaVO$_3$/SrTiO$_3$.

description: In this work, the potential effect of atmospheric haze caused by dust aerosols on the spectral mismatch factor (SF) of monocrystalline photovoltaic cells is analyzed. To that effect, SF is calculated using the SMARTS spectral code and inputs provided by either AERONET sunphotometric data or spectroradiometric solar irradiance measurements conducted at the Plataforma Solar de Almería (PSA), southern Spain, under clear and hazy days. Using AERONET data as inputs to the SMARTS model, it is found that its simulations closely correspond to the direct normal irradiance measurements obtained with a spectroradiometer. SF is evaluated with SMARTS for a large range of aerosol conditions and air mass values, also using various tilt angles and two aerosol models, so as to cover a large variety of situations that can occur at PSA or elsewhere. It is found that, although SF generally remains close to 1, various combinations of these varying conditions can make SF oscillate between overall gains or losses, even during a single day. The impact of air mass is found generally more important than that of the atmospheric aerosol load, even under very dusty or hazy conditions.

description: We present an independent analysis of expected real-world performance of single junction perovskite cells and tandem perovskite-on-silicon devices relative to single junction silicon cells. As energy-rating of perovskite devices is not yet realised and the technology is still rapidly maturing, this is a theoretical study. We create an “optimistic” scenario, which represents successful upscaling of current record-efficiency perovskite lab cells. Our model considers temperature, spectral, angular and junction mismatch effects. In this scenario, we find that single-junction perovskite cells perform better in many real-world climates than under standard test conditions; in one climate, the single junction perovskite cell has a higher absolute energy yield than a silicon cell that had 3 % higher efficiency under standard test conditions. For tandem cells, we find that tandem energy gains of between 29 % and 40 % are achieved when the band gap of the front cell is optimised to the climate. We also simulate less optimistic scenarios by reducing the performance of both the perovskite or silicon sub cells. We find that tandem energy gain is strongly affected by the initial choice of sub-cell efficiency, which largely explains the large variations in published modelling studies.

Seasonality, sinking and the chlorophyll maximum of an oligotrophic British Columbia lake
Creators: name: Jackson, Leland J.
Publisher: name: University of British Columbia
Year: 2010

description: A field investigation was carried out over two seasonal periods on an oligotrophic coastal British Columbia lake to determine the role of sinking in the formation of the chlorophyll maximum as well as some aspects of phytoplankton seasonality. Sinking rates of two diatoms were measured and found to be highest in the epilimnion and lowest at the depth of the chlorophyll maximum. Light affected sinking rate as well as the position of the chlorophyll maximum. The chlorophyll maximum formed at 10-12 m following the onset of seasonal thermal stratification and descended to ca. 22 m for the summer. A major factor in the formation of the chlorophyll maximum is the decrease of phytoplankton sinking rate at depth. Rhizosolenia eriensis is one of the first phytoplankters to bloom in the spring. Small flagellates (3-15 um) and occasionally Dinobryon sp. were also important numerically. In the summer Cyclotella spp. displaced R. eriensis as the dominant diatom in the epilimnion. The relative timing of seasonal maxima of blooms of various species remained similar during the two years investigated. Lake fertilization affected the phytoplankton standing stock. R. eriensis did not greatly benefit from fertilization since it sank out of the epilimnion and became a major constituent of the chlorophyll maximum before fertilization. Because of its large size and low C : cell volume ratio due to a large vacuole, R. eriensis is probably not a good food source for zooplankton.

description: We examine a large set of synthetic quasar spectra to realistically assess the potential of using the relative sizes of highly ionized near-zones in the Lya and Lyb forest as a probe of the neutral hydrogen content of the intergalactic medium (IGM) at z>6. The scatter in the relative near-zone size distribution, induced by underlying fluctuations in the baryonic density field and the filtering of ionizing radiation, is considerable even for fixed assumptions about the IGM neutral fraction. As a consequence, the current observational data cannot distinguish between an IGM which is significantly neutral or highly ionized just above z=6. Under standard assumptions for quasar ages and ionizing luminosities, a future sample of several tens of high resolution Lya and Lyb near-zone spectra should be capable of distinguishing between a volume weighted neutral hydrogen fraction in the IGM which is greater or less than 10 per cent.

description: We study the $ππN$ system by solving the Faddeev equations, for which the input two-body $t$-matrices are obtained by solving the Bethe-Salpeter equation in the coupled channel formalism. The potentials for the $ππ$, $πN$ sub-systems and their coupled channels are obtained from chiral Lagrangians, which have been earlier used to study resonances in these systems successfully. In this work, we find a resonance in the $ππN$ system with a mass of $1704 - i 375/2$ MeV and with quantum numbers $I=1/2$, $J^π=1/2^+$. We identify this state with the $N^*(1710)$. This peak is found where the energies of the $ππ$ sub-system fall in the region of the $σ$ resonance. We do not find evidence for the Roper resonance in our study indicating a more complex structure for this resonance, nor for any state with total isospin $I=3/2$ or $5/2$.

description: The combined stress tests, in which some kinds of stressors simultaneously applied to the testing PV modules, have several advantages to contribute the risk avoidance on long-term operation of PV modules in fields (find the failure modes which are a-priori unknown in new module designs, reduction of potential risk, acceleration of the time to market of a product, and so on). Through the analyses for the cost-of-ownerships in the conventional qualification test and the proposed extended stress tests for PV modules, we predict that of a combined stress test, to clarify the acceptable level of investment for this novel test system. In this study, we demonstrate that, if we could develop the test equipment with a comparable cost to those required in these extended stress tests, the combined stress test would be accepted by all stake-holders in PV industry sector. Furthermore, it is suggested that the market penetration of this combined stress test would be facilitated by the equipment-improvement for the multi-module testing.
WinCrtclas, a Windows program for cerite-supergroup minerals✝
Creators: name: Yavuz, Fuat
Publisher: name: Periodico di Mineralogia
Year: 2025

description: A Microsoft® Visual Basic software, WinCrtclas, has been developed to calculate the chemical formulas of cerite-supergroup minerals (CSM) based on data obtained from wet-chemical and electron-microprobe analyses. WinCrtclas currently evaluates 17 valid mineral species using the Commission on New Minerals, Nomenclature and Classification (CNMMC) of the International Mineralogical Association (IMA) nomenclature scheme in the general formula A9XM[T7O24Ø4]Z3. The program recalculates the compositional formulas of CSM based on 28 oxygen atoms with the T-site total of 7.00 normalization option. Mineral formulas of the CSM are calculated considering the valency-imposed double site occupancy and the site total charge approach, allowing a double suffix to state the essential A constituents in the general formula. WinCrtclas operates in four stages: (1) it estimates cation and anion contents provided by input chemical data; (2) it determines the dominant cation and anion at the A, X, M, T and Z sites; (3) it assigns the CSM based on the dominant cations and anions at these sites; and (4) it classifies the species into an appropriate groups. WinCrtclas allows users to: (1) enter up to 41 input variables for mineral-chemical analyses; (2) type and load multiple CSM compositions in the data entry section; (3) edit and load the Microsoft® Excel files used in calculating, classifying, and naming the CSM, and (4) store all the calculated parameters in the output of a Microsoft® Excel file for further data evaluations.

description: Defects in semiconductors have been studied for over 60 years. In this time there has been significant progress in measuring and understanding of these defects. This development has led to various types of defect parameters being reported. A large proportion of these are not suitable to accurately determine the impact of a defect on the performance/lifetime of a device. This paper outlines these developments and different values that have been reported. It then suggests a path so that the correct values important for lifetime can be determined.

description: The heteronemertean Cerebratulus marginatus Renier, 1804 is a well-known representative of the family Lineidae (Nemertea) inhabiting sandy or muddy sediments throughout the world. Due to its wide geographic distribution and the lack of distinctive external morphological features among different populations, the species has been considered cosmopolitan. Increasing evidence indicates that nemertean species, including Cerebratulus marginatus, described based on morphology are often not supported by genetic data and represent complexes of cryptic species, rather than cosmopolitan species. Here, we use species delimitation and phylogenetic analyses to evaluate the speciation patterns within the putative C. marginatus species complex. We examined 25 specimens morphologically ascribed to C. marginatus and closely related species using a multilocus dataset including two mitochondrial markers (16S rRNA, COI) and three nuclear markers (18S rRNA, 28S rRNA, H3). Our analyses identified at least four supported independent lineages among the populations analysed, indicating that samples identified as C. marginatus might represent indeed a complex of cryptic species. Therefore, our results do not support the cosmopolitanism of C. marginatus and provide additional evidence suggesting that species identifications in nemerteans should not be based exclusively on morphological or anatomical features which do not accurately reflect evolutionary patterns. Our study highlights the importance of including molecular data in addition to morphological information to accurately delimit species boundaries, thereby improving nemertean taxonomy by providing a more accurate picture of the true species diversity and geographic distribution of this typically neglected phylum.

description: We study the Navier-Stokes steady states for a low density monodisperse hard sphere granular gas (i.e, a hard sphere ideal monatomic gas with inelastic interparticle collisions). We present a classification of the uniform steady states that can arise from shear and temperature (or energy input) applied at the boundaries (parallel walls). We consider both symmetric and asymmetric boundary conditions and find steady states not previously reported, including sheared states with linear temperature profiles. We provide explicit expressions for the hydrodynamic profiles for all these steady states. Our results are validated by the numerical solution of the Boltzmann kinetic equation for the granular gas obtained by the direct simulation Monte Carlo method, and by molecular dynamics simulations. We discuss the physical origin of the new steady states and derive conditions for the validity of Navier-Stokes hydrodynamics.

description: An important process step for galvanic metallization on transparent conducting oxide (TCO) is the preparation of a plating mask, which is an electrically insolating layer in the area where no metal deposition is desired. A polymer ink is often used for this purpose. A disadvantage, however, is that the front side of the solar cell is largely coated with polymer, hence large amounts of it must be recovered or, even worse, disposed of together with the solvents used in the later stripping process. To reduce costs, we take a different approach, namely screen-printing a polymer ink in the form of the later front metal grid, applying a full-area SiO2 coating at room temperature and lift off. This way we obtain a SiO2 instead of a polymer plating mask. At first glance, replacing polymer ink with SiO2 coating does not seem to be cost-effective. However, we have used a new atmospheric pressure chemical vapor deposition (APCVD) technology developed by us that potentially has very low investment and operating costs. In this work, we investigated this approach and demonstrated the performance of the SiO2 plating mask on heterojunction Si solar cells.

description: O uso intensivo das redes de computadores baseadas em IP e a crescente demanda
 de utilização das aplicações de tempo real como VoIP e outras aplicações multimídia,
 intensifica a coexistência de tráfegos distintos na rede e a necessidade de um melhor
 gerenciamento da infraestrutura de rede. Soluções tradicionais de qualidade de
 serviço são propostas, porém são consideradas insuficientes pois são baseadas
 apenas em métricas de rede. Observa-se, portanto a necessidade de uma
 transformação na maneira em que as redes devem se comportar, onde as decisões
 devem ser centradas no usuário final, e a Qualidade de Experiência (QoE) é
 fundamental para essa mudança pois muda o foco da avaliação de qualidade, da rede
 para o usuário. O arcabouço Context-Aware Adaptative Routing Framework (CAARF)
 e mais especificamente, o CAARF-SDN implementação inspirada no arcabouço
 CAARF, são soluções de otimização sensíveis ao contexto que são propostas de
 forma a viabilizar o encaminhamento do tráfego de rede baseado em informações de
 contexto de forma dinâmica. Integrado ao modelo de contexto destas soluções estão
 os conceitos de QoE, QoS e QoD. Tendo em vista o que é proposto pelo CAARF-SDN
 este trabalho tem como objetivo o desenvolvimento de uma solução de coleta da
 qualidade de experiência que se adequa ao CAARF-SDN. A solução proposta tratase de um agente de software capaz de estimar a qualidade de experiência para
 aplicações de voz, que ao receber requisições do CAARF-SDN utiliza pacotes UDP
 para estimar métricas de QoS que serão utilizas como parâmetros em seu modelo de
 estimação de qualidade de experiência.

description: We study the problem of merging three-dimensional points that are nearby or coincident. We introduce a fast, efficient approach that uses data parallel techniques for execution in various shared-memory environments. Our technique incorporates a heuristic for efficiently clustering spatially close points together, which is one reason our method performs well against other methods. We then compare our approach against methods of a widely-used scientific visualization library accompanied by a performance study that shows our approach works well with different kinds of parallel hardware (many-core CPUs and NVIDIA GPUs) and data sets of various sizes.

description: Anthomyiidae is a family of flies distributed worldwide comprising approximately 2,000 species, which, based on molecular analyses, belong to the Muscoidea grade. The phylogenetic data for this family are limited and the Neotropical lineages have never been studied at the molecular level. Herein, we present the first phylogenetic analyses of Anthomyiidae including Neotropical taxa. The resulting phylogenetic trees – inferred using maximum-likelihood and Bayesian criteria and based on two nuclear and three mitochondrial genes and 56 terminals, including 13 Neotropical anthomyiid species – confirmed Anthomyiidae as a monophyletic lineage and sister group of Scathophagidae, which is also monophyletic. The clade Coenosopsia + Phaonantho was not recovered as a sister group of the remaining anthomyiids, as previously indicated by the results of morphological analyses. These and other generic relationships are discussed in the light of morphological data from previous studies. The divergence time estimation suggested that after a split from the Oestroidea clade approximately 51.7 Ma, the radiation of Anthomyiidae + Scathophagidae began during the Eocene, with the oldest common ancestor of both families living approximately 40.5 Ma and with the oldest anthomyiid ancestor living approximately 36.8 Ma. The split of the clade Coenosopsia + Phaonantho was dated to the Oligocene (c. 23 Ma). These results provide new insights into the timing and rate of anthomyiid and scathophagid fly evolution.

description: Because of the spatial separation of high performance compute resources and immersive visualization systems, their combined use requires remote visualization. Remote rendering incurs increased latency from user interaction to display. For immersive virtual environments, this latency is a bigger problem than for desktop visualization. With hybrid remote visualization we enable the exploration of large-scale remote data sets from immersive virtual environments. This is based on three factors: When appropriate, we enable the local rendering of remote objects. We decouple local interaction from remote rendering as far as possible by depth compositing of remote and local images at a rate independent from remote rendering. Finally, we try to hide this latency by reprojecting 2.5D images for changed viewer positions. In this paper we describe the integration of hybrid remote rendering into the data-parallel visualization system Vistle as well its extension to a distributed system. Thereby arbitrary combinations of object-based and image-based remote visualization become possible.

description: Modern real-time visualizations of large-scale datasets require constant high frame rates while their datasets might exceed the available graphics memory. This requires sophisticated upload strategies from host memory to the memory of the graphics cards. A possible solution uses outsourcing of all data uploads onto concurrent threads and disconnecting prohibitive data dependencies. OpenGL provides a variety of functions and parameters but not all allow minimal interference on rendering. In this work, we present a thorough and statistically sound analysis of various effects introduced by choosing different input parameters, such as size, partitioning and number of threads for uploading, as well as combinations of buffer usage hints and uploading functions. This approach provides insight into the problem and offers a basis for future optimizations.
