description: Fully convolutional neural networks (FCN) are successfully used for the automated pixel-wise classification of aerial images and possibly additional data. However, they require many labelled training samples to perform well. One approach addressing this issue is semi-supervised domain adaptation (SSDA). Here, labelled training samples from a source domain and unlabelled samples from a target domain are used jointly to obtain a target domain classifier, without requiring any labelled samples from the target domain. In this paper, a two-step approach for SSDA is proposed. The first step corresponds to a supervised training on the source domain, making use of strong data augmentation to increase the initial performance on the target domain. Secondly, the model is adapted by entropy minimization using a novel weighting strategy. The approach is evaluated on the basis of five domains, corresponding to five cities. Several training variants and adaptation scenarios are tested, indicating that proper data augmentation can already improve the initial target domain performance significantly resulting in an average overall accuracy of 77.5%. The weighted entropy minimization improves the overall accuracy on the target domains in 19 out of 20 scenarios on average by 1.8%. In all experiments a novel FCN architecture is used that yields results comparable to those of the best-performing models on the ISPRS labelling challenge while having an order of magnitude fewer parameters than commonly used FCNs. © 2020 Copernicus GmbH.

description: The electric dipole (E1) strength functions have been systematically calculated based on the time-dependent density functional theory (TDDFT), using the finite amplitude method and the real-time approach to the TDDFT with pairing correlations. The low-energy E1 strengths in neutron-rich isotopes show peculiar behaviors, such as sudden enhancement and reduction, as functions of the neutron numbers.They seem to be due to the interplay between the neutron shell effect and the deformation effect.

description: Land use (LU) is an important information source commonly stored in geospatial databases. Most current work on automatic LU classification for updating topographic databases considers only one category level (e.g. residential or agricultural) consisting of a small number of classes. However, LU databases frequently contain very detailed information, using a hierarchical object catalogue where the number of categories differs depending on the hierarchy level. This paper presents a method for the classification of LU on the basis of aerial images that differentiates a fine-grained class structure, exploiting the hierarchical relationship between categories at different levels of the class catalogue. Starting from a convolutional neural network (CNN) for classifying the categories of all levels, we propose a strategy to simultaneously learn the semantic dependencies between different category levels explicitly. The input to the CNN consists of aerial images and derived data as well as land cover information derived from semantic segmentation. Its output is the class scores at three different semantic levels, based on which predictions that are consistent with the class hierarchy are made. We evaluate our method using two test sites and show how the classification accuracy depends on the semantic category level. While at the coarsest level, an overall accuracy in the order of 90% can be achieved, at the finest level, this accuracy is reduced to around 65%. Our experiments also show which classes are particularly hard to differentiate. © 2020 Copernicus GmbH. All rights reserved.

Full counting statistics as a probe of quantum coherence in a side-coupled double quantum dot system

description: We study theoretically the full counting statistics of electron transport through side-coupled double quantum dot (QD) based on an efficient particle-number-resolved master equation. It is demonstrated that the high-order cumulants of transport current are more sensitive to the quantum coherence than the average current, which can be used to probe the quantum coherence of the considered double QD system. Especially, the quantum coherence plays a crucial role in determining whether the super-Poissonian noise occurs in the weak inter-dot hopping coupling regime depending on the corresponding dot-lead coupling, and the corresponding values of super-Poissonian noise can be relatively enhanced when considering the spins of conduction electrons. Moreover, this super-Poissonian noise bias range depends on the singly-occupied eigenstates of the system, which thus suggests a tunable super-Poissonian noise device. The occurrence-mechanism of super-Poissonian noise can be understood in terms of the interplay of quantum coherence and effective competition between fast-and-slow transport channels.

description: Chemical adsorption of the species at semiconductor surfaces is analyzed showing the existence of the two contributions to adsorption energy: bond creation and charge transfer. It is shown that the energy of quantum surface states is affected by the electric field at the surface, nevertheless the potential contribution of electron and nuclei cancels out. The charge transfer contribution is Fermi level independent for pinned surfaces. Thus for Fermi level pinned at the surface, the adsorption energy is independent on the Fermi energy i.e. the doping in the bulk. The DFT simulations of adsorption of hydrogen at clean GaN(0001) and silicon at SiC(0001) surfaces confirmed independence of adsorption energy on the doping in the bulk. For the Fermi level nonpinned surfaces the charge contribution depends on the position of Fermi level in the bulk. Thus adsorption energy is sensitive to change of the Fermi energy in the bulk, i.e. the doping. The DFT simulations of adsorption of atomic hydrogen at 0.75 ML hydrogen covered GaN(0001) surface confirmed that the adsorption energy may be changed by about 2 eV by the doping change from n- to p-type.

description: Slides used during the ELIXIR 2024 All Hands Meeting MiniSymposium titled: "Enriching synergies across the ELIXIR Training Platform and the Science Tier"

The main theme of the mini-symposium is towards finding the appropriate connections and building bridges between the planned efforts across the ELIXIR Training Platform, and the activities of the ELIXIR Science Tier. This bidirectional interaction will be facilitated by flash presentations of the individual Work Packages in the TrP, complemented by an overview of the different Science Priorities with Training in mind. Ultimately, the session will conclude with an open Panel discussion, towards identifying the most viable synergies in the short-term, while also building a longer-term connection across the key elements of the Science Tier.

The ELIXIR Training Platform (TrP) is building a network of training resources and services, aiming for collaboration, visibility, and standardisation. SPLASH, a digital hub, showcases core services like TeSS, enhancing the training life cycle. Work Packages focus on infrastructure, guidelines, and Train-the-Trainer resources. Collaboration across ELIXIR entities is essential, as are standardised guidelines and a supportive community for knowledge sharing. The project's success will transform training delivery within the community.

description: Modern machine learning, especially deep learning, which is used in a variety of applications, requires a lot of labelled data for model training. Having an insufficient amount of training examples leads to models which do not generalize well to new input instances. This is a particular significant problem for tasks involving aerial images: Often training data is only available for a limited geographical area and a narrow time window, thus leading to models which perform poorly in different regions, at different times of day, or during different seasons. Domain adaptation can mitigate this issue by using labelled source domain training examples and unlabeled target domain images to train a model which performs well on both domains. Modern adversarial domain adaptation approaches use unpaired data. We propose using pairs of semantically similar images, i.e., whose segmentations are accurate predictions of each other, for improved model performance. In this paper we show that, as an upper limit based on ground truth, using semantically paired aerial images during training almost always increases model performance with an average improvement of 4.2% accuracy and .036 mean intersection-over-union (mIoU). Using a practical estimate of semantic similarity, we still achieve improvements in more than half of all cases, with average improvements of 2.5% accuracy and .017 mIoU in those cases. © 2020 Copernicus GmbH.

title: Field Evaluation of Tobacco Engineered for High Leaf-Oil Accumulation
Creators: name: Perry, James
Publisher: name: University of Kentucky Libraries

description: The biofuel market is dominated by ethanol and biodiesel derived from cellulosic and lipid-based biomass crops. This is largely due to the relatively low costs and reliability of production. At present, production of non-food plant-derived oils for biofuel production in the U.S. is minimal. A research team from the Commonwealth Scientific and Industrial Research Organization (CSIRO), an independent Australian federal government research institution, has developed an efficient transgenic system to engineer oil production in tobacco leaves. This novel system is comprised of multiple transgenes that direct the endogenous metabolic flux of oil precursors towards triacylglycerol (TAG) production. Additional genes were incorporated to store and protect the accumulated oil in vegetative tissues. Preliminary greenhouse tests by the CSIRO research group indicated an oil content of > 30% by dry weight (DW) in tobacco leaf lamina. Here we evaluated two transgenic lines against a non-transgenic control in 2017 and 2018 in greenhouse and field production systems. The 2017 pilot study showed that the high leaf-oil tobacco line was viable and will grow in the field in Kentucky. Chemical analyses revealed significantly higher oil content compared to the non-transgenic control despite several logistical setbacks. These promising discoveries prompted the deployment of additional transgenic line assessments and further data validation in 2018. Line evaluations in 2018 revealed that the LEC2:WRI1:DGAT:OLE transgenic line had the highest leaf oil content (≥ 19.3% DW-1) compared to both the WRI1:DGAT:OLE transgenic line (≤ 5.6% DW-1) and non-transgenic control (≤ 2.1% DW-1). The results of this research will contribute to the successful development of transgenic tobacco lines engineered to accumulate high concentrations of TAG in the leaves.

description: State-of-the-art object detection approaches such as Fast/Faster R-CNN, SSD, or YOLO have difficulties detecting dense, small targets with arbitrary orientation in large aerial images. The main reason is that using interpolation to align RoI features can result in a lack of accuracy or even loss of location information. We present the Local-aware Region Convolutional Neural Network (LR-CNN), a novel two-stage approach for vehicle detection in aerial imagery. We enhance translation invariance to detect dense vehicles and address the boundary quantization issue amongst dense vehicles by aggregating the high-precision RoIs' features. Moreover, we resample high-level semantic pooled features, making them regain location information from the features of a shallower convolutional block. This strengthens the local feature invariance for the resampled features and enables detecting vehicles in an arbitrary orientation. The local feature invariance enhances the learning ability of the focal loss function, and the focal loss further helps to focus on the hard examples. Taken together, our method better addresses the challenges of aerial imagery. We evaluate our approach on several challenging datasets (VEDAI, DOTA), demonstrating a significant improvement over state-of-the-art methods. We demonstrate the good generalization ability of our approach on the DLR 3K dataset. © 2020 Copernicus GmbH. All rights reserved.

description: Federated learning (FL) provides a variety of privacy advantages by allowing clients to collaboratively train a model without sharing their private data. However, recent studies have shown that private information can still be leaked through shared gradients. To further minimize the risk of privacy leakage, existing defenses usually require clients to locally modify their gradients (e.g., differential privacy) prior to sharing with the server. While these approaches are effective in certain cases, they regard the entire data as a single entity to protect, which usually comes at a large cost in model utility. In this paper, we seek to reconcile utility and privacy in FL by proposing a user-configurable privacy defense, RecUP-FL, that can better focus on the user-specified sensitive attributes while obtaining significant improvements in utility over traditional defenses. Moreover, we observe that existing inference attacks often rely on a machine learning model to extract the private information (e.g., attributes). We thus formulate such a privacy defense as an adversarial learning problem, where RecUP-FL generates slight perturbations that can be added to the gradients before sharing to fool adversary models. To improve the transferability to un-queryable black-box adversary models, inspired by the idea of meta-learning, RecUP-FL forms a model zoo containing a set of substitute models and iteratively alternates between simulations of the white-box and the black-box adversarial attack scenarios to generate perturbations. Extensive experiments on four datasets under various adversarial settings (both attribute inference attack and data reconstruction attack) show that RecUP-FL can meet user-specified privacy constraints over the sensitive attributes while significantly improving the model utility compared with state-of-the-art privacy defenses.

description: If to govern a modern state – in a Foucaultian manner – is understood as a relationship of force between population and state, one has to take into account the changes in behaviour, self-consciousness and techniques of control which can be detected for both government and citizen. Even ones’ own identity seems to be embedded, organized and protected by various regulations and restrictions. These aspects provoke the question whether a self-identical modulation of ones’ identity could be possible? This article discusses – by using the example of the self-modification of Luigi Pirandellos Il fu Mattia Pascal – under which circumstances a subject defines itself as independent and tries to modify its identity. Furthermore it will be investigated which mechanisms of regulation, inner conflicts and restrictions affect the subject in its’ venture. The analysis will be based on theories of Michel Foucault, Pierre Bourdieu as well as concepts of Roberto Esposito.

description: We present the evolution of the initial (up to ~ 10 kbar) hydrostatic, pressure dependencies of Tc and of the ambient pressure jump in the heat capacity associated with the superconducting transition as a function of K - doping in the Ba1-xKxFe2As2 family of iron-based superconductors. The pressure derivatives show weak but distinct anomaly near x ~ 0.7. In the same concentration region Delta Cp at Tc deviates from the Delta Cp ~ T^3 scaling found for most BaFe2As2 - based superconductors. These results are consistent with a Lifshitz transition, and possible significant modification of the superconducting state, occurring near x ~ 0.7.

description: We construct and analyze thermal spinning giant gravitons in type II/M-theory based on spherically wrapped black branes, using the method of thermal probe branes originating from the blackfold approach. These solutions generalize in different directions recent work in which the case of thermal (non-spinning) D3-brane giant gravitons was considered, and reveal a rich phase structure with various new properties. First of all, we extend the construction to M-theory, by constructing thermal giant graviton solutions using spherically wrapped M2- and M5-branes. More importantly, we switch on new quantum numbers, namely internal spins on the sphere, which are not present in the usual extremal limit for which the brane world volume stress tensor is Lorentz invariant. We examine the effect of this new type of excitation and in particular analyze the physical quantities in various regimes, including that of small temperatures as well as low/high spin. As a byproduct we find new stationary dipole-charged black hole solutions in AdS_m X S^n backgrounds of type II/M-theory. We finally show, via a double scaling extremal limit, that our spinning thermal giant graviton solutions lead to a novel null-wave zero-temperature giant graviton solution with a BPS spectrum, which does not have an analogue in terms of the conventional weakly coupled world volume theory.

In: EMV 2012, Internationale Fachmesse und Kongress für Elektromagnetische Verträglichkeit. Düsseldorf, 2012]. Hohe übertragene Leistungen und steile Taktflanken lassen die HV-Leitungen zu Quellen hochfrequenter Störemission werden. Um diese Effekte besser erschließen zu können, ist es notwendig, die Vorgänge im Inneren des geschirmten HV-Systems zu erfassen. Dies kann durch eine breitbandige Messung der zeitaufgelösten Ströme und Spannungen direkt auf den HV-Leitungen erreicht werden. Die derzeitigen Lösungen für diese Messungen (Spannungsteiler, Rogowskispule, Stromzange, Shunt-Widerstand und Hallsensor) haben jedoch den Nachteil, dass dadurch insbesondere die EMV-relevanten hochfrequenten Störanteile der zu vermessenden Systemkomponenten nicht erfasst oder zumindest deutlich beeinflusst werden. Daher stellt dieser Beitrag ein neu entwickeltes Messverfahren vor, das diese Nachteile nicht aufweist. In Kapitel 2 werden Kalibrierung und Messung im Detail vorgestellt und verifiziert. In Kapitel 3 wird der Messaufbau zum Einsatz in Elektrofahrzeugen dargestellt. Weiterhin wird die Bedeutung der Rückwirkungsfreiheit des entwickelten Verfahrens hervorgehoben, bevor erste Messungen an einem Fahrzeug durchgeführt werden.

description: Antenna arrays can be either reciprocity calibrated (R-calibrated), which facilitates reciprocity-based beamforming, or fully calibrated (F-calibrated), which additionally facilitates transmission and reception in specific physical directions. We first expose, to provide context, the fundamental principles of over-the-air R- and F-calibration of distributed arrays. We then describe a new method for calibration of two arrays that are individually F-calibrated, such that the combined array becomes jointly F-calibrated.

description: We investigate the complete next-to-leading order (NLO) QCD corrections to $Υ(1S) +W$ production at the LHC, and predict theoretically the distribution of the $Υ(1S)$ transverse momentum. We analyse the contributions from different components up to the QCD NLO in the \ppUW process. Our results show that the \ppUW process has a large production rate and could be potentially detected at the LHC. We see that the differential cross section for the $Υ(1S)$ direct-production at the LO is significantly enhanced by the QCD corrections, and the $b\bar{b} [ ^3S_1^{(8)} ]$ contribution component dominates in the whole plotted $p_T^{Υ(1S)}$ region. We have also calculated the $Υ(1S)$ meson indirect-productions via feed-down decays of $Υ(2S)$, $Υ(3S)$, $χ_{b1}(1P)$, $χ_{b2}(1P)$, $χ_{b1}(2P)$, and $χ_{b2}(2P)$ mesons. We find that the $Υ(1S)$ indirect-productions can give important contributions to the distribution of $p_T^{Υ(1S)}$ for the \ppUW process at the NLO. We conclude that the studying the $Υ(1S)+W$ production at the LHC could provide an interesting opportunity in testing the nonrelativistic QCD factorization formalism.

description: We present survey results obtained from the UBVRI optical photometric follow-up of 19 bright core-collapse SNe during 2002-2012 using 1-m class optical telescopes operated by the Aryabhatta Research Institute of Observational Science (acronym ARIES), Nainital India. This homogeneous set of data have been used to study behavior of optical light/color curve, and to gain insight into object-to-object peculiarity. We derive integrated luminosities for types IIP, Ibc and luminous SNe. Two peculiar type IIP events having photometric properties similar to normal IIP and spectroscopic properties similar to sub-luminous IIP have been identified.

description: In this paper the quantum vacuum energies induced by massive fluctuations of one real scalar field on a configuration of two partially transparent plates are analysed. The physical properties of the infinitely thin plates are characterized by two Dirac-$δ$ potentials. We find that an attractive/repulsive Casimir force arises between the plates when the weights of the $δ$'s have equal/different sign. If some of the plates absorbs fluctuations below some threshold of energy (the corresponding weight is negative) there is the need to set a minimum mass to the scalar field fluctuations to preserve unitarity in the corresponding quantum field theory. Two repulsive $δ$-interactions are compatible with massless fluctuations. The effect of Dirichlet boundary conditions at the endpoints of the interval $(-a,a)$ on a massless scalar quantum field theory defined on this interval is tantamount letting the weights of the repulsive $δ$-interactions to $+\infty$.

description: Dynamical maps describe general transformations of the state of a physical system, and their iteration can be interpreted as generating a discrete time evolution. Prime examples include classical nonlinear systems undergoing transitions to chaos. Quantum mechanical counterparts show intriguing phenomena such as dynamical localization on the single particle level. Here we extend the concept of dynamical maps to an open-system, many-particle context: We experimentally explore the stroboscopic dynamics of a complex many-body spin model by means of a universal quantum simulator using up to five ions. In particular, we generate long-range phase coherence of spin by an iteration of purely dissipative quantum maps. We also demonstrate the characteristics of competition between combined coherent and dissipative non-equilibrium evolution. This opens the door for studying many-particle non-equilibrium physics and associated dynamical phase transitions with no immediate counterpart in equilibrium condensed matter systems. An error detection and reduction toolbox that facilitates the faithful quantum simulation of larger systems is developed as a first step in this direction.

Deconstructing Hierarchy in the Traditional Performing Arts of Japan: The Music of Kamigata Rakugo
Creators: name: Hallett, Catherine
Publisher: name: The Australian National University
Year: 2020

description: Rakugo, the art of staged comic storytelling of Japan, is generally classified as and perceived by audiences to be an oral tradition performed without significant musical accompaniment. This is due to the belief that rakugo is an art form of the Kanto region where music is seldom used, and that rakugo performed in the Kansai region is merely a regional offshoot of the tradition proper. Kamigata rakugo is nevertheless its own distinct tradition and music is a crucial component of it. Music is employed from start to finish, and it ties storyteller to storyteller, story to story, and audience to performance. However, the primary issue with the existing literature is that the music and musicians are not given much recognition and are considered separate from the stories and storytellers. Scholars have not given much recognition to the centrality of those who perform the music in the tradition, and the interaction that takes place between the storytellers and musicians as they prepare for a performance. To address these shortcomings in the extant literature I conducted ethnographic research in Japan that included undertaking a temporary apprenticeship to become a musician of rakugo. The central question guiding this research was "why is music essential to Kamigata rakugo?" For my study I was able to access the musicians' room located in the inner sanctuary of the yose theatre and engage with the storytellers and musicians regarding the stories and music. Unlike many other scholars, therefore, I was able to consider Kamigata rakugo as a complete performing practice. I realised that while all performers appeared from the outside to follow a strict vertical hierarchical structure, this was not a sufficient representation of how things were actually operating on the inside. As I considered the ways in which storytellers negotiate the use of music with the female musicians I was struck by the steadfast assertion by some storytellers or female musicians that the music cannot be altered, while other storytellers or female musicians had a deliberate disregard for the rules and changed them as they pleased. A subsidiary question that this research addresses therefore is "how does hierarchy support music's essential role?" Over the course of my fieldwork it was clear to me there are many different forms of authority or capital inherent to the working of the tradition but the most influential are knowledge, gender, seniority, kinship, status, and role. The musical arena in Kamigata rakugo is a space for promoting, resisting, and subverting positions of authority and ultimately hierarchy. In this study I argue that hierarchy should not simply be viewed as a simple linear structure. Rather than simply radiating downwards, it constitutes a dynamic web of relationships.

description: Context. The Lyman alpha emission line of galaxies is an important tool for finding galaxies at high redshift, and thus probe the structure of the early universe. However, the resonance nature of the line and its sensitivity to dust and neutral gas is still not fully understood. Aims. We present measurements of the velocity, covering fraction and optical depth of neutral gas in front of two well known local blue compact galaxies that show Lyman alpha in emission: ESO 338-IG 04 and Haro 11. We thus test observationally the hypothesis that Lyman alpha can escape through neutral gas by being Doppler shifted out of resonance. Methods. We present integral field spectroscopy from the GIRAFFE/Argus spectrograph at VLT/FLAMES in Paranal, Chile. The excellent wavelength resolution allows us to accurately measure the velocity of the ionized and neutral gas through the H-alpha emission and Na D absorption, which traces the ionized medium and cold interstellar gas, respectively. We also present independent measurements with the VLT/X-shooter spectrograph which confirm our results. Results. For ESO 338-IG04, we measure no significant shift of neutral gas. The best fit velocity is -15 (16) km/s. For Haro 11, we see an outflow from knot B at 44 (13) km/s and infalling gas towards knot C with 32 (12) km/s. Based on the relative strength of the Na D absorption lines, we estimate low covering fractions of neutral gas (down to 10%) in all three cases. Conclusions. The Na D absorption likely occurs in dense clumps with higher column densities than where the bulk of the Ly-alpha scattering takes place. Still, we find no strong correlation between outflowing neutral gas and a high Lyman alpha escape fraction. The Lyman alpha photons from these two galaxies are therefore likely escaping due to a low column density and/or covering fraction.
