description: Vertically stacking two dimensional (2D) materials can enable the design of novel electronic and optoelectronic devices and realize complex functionality. However, the fabrication of such artificial heterostructures in wafer scale with an atomically-sharp interface poses an unprecedented challenge. Here, we demonstrate a convenient and controllable approach for the production of wafer-scale 2D GaSe thin films by molecular beam epitaxy. In-situ reflection high-energy electron diffraction oscillations and Raman spectroscopy reveal a layer-by-layer van der Waals epitaxial growth mode. Highly-efficient photodetector arrays were fabricated based on few-layer GaSe on Si. These photodiodes show steady rectifying characteristics and a relatively high external quantum efficiency of 23.6%. The resultant photoresponse is super-fast and robust with a response time of 60 us. Importantly, the device shows no sign of degradation after 1 million cycles of operation. Our study establishes a new approach to produce controllable, robust and large-area 2D heterostructures and presents a crucial step for further practical applications.

description: In the sixth of the series of papers reporting on a large reverberation mapping (RM) campaign of active galactic nuclei (AGNs) with high accretion rates, we present velocity-resolved time lags of H$β$ emission lines for nine objects observed in the campaign during 2012$-$2013. In order to correct the line-broadening caused by seeing and instruments before the analysis of velocity-resolved RM, we adopt Richardson-Lucy deconvolution to reconstruct their H$β$ profiles. The validity and effectiveness of the deconvolution are checked out by Monte Carlo simulation. Five among the nine objects show clear dependence of time delay on velocity. Mrk 335 and Mrk 486 show signatures of gas inflow whereas the clouds in the broad-line regions (BLRs) of Mrk 142 and MCG +06-26-012 tend to be radial outflowing. Mrk 1044 is consistent with the case of virialized motions. The lags of the rest four are not velocity-resolvable. The velocity-resolved RM of super-Eddington accreting massive black holes (SEAMBHs) shows that they have diversity of the kinematics in their BLRs. Comparing with the AGNs with sub-Eddington accretion rates, we do not find significant differences in the BLR kinematics of SEAMBHs.

description: We report experimental measurements of the translational and rotational dynamics of a large buoyant sphere in isotropic turbulence. We introduce an efficient method to simultaneously determine the position and (absolute) orientation of a spherical body from visual observation. The method employs a minimization algorithm to obtain the orientation from the 2D projection of a specific pattern drawn onto the surface of the sphere. This has the advantages that it does not require a database of reference images, is easily scalable using parallel processing, and enables accurate absolute orientation reference. Analysis of the sphere's translational dynamics reveals clear differences between the streamwise and transverse directions. The translational auto-correlations and PDFs provide evidence for periodicity in the particle's dynamics even under turbulent conditions. The angular autocorrelations show weak periodicity. The angular accelerations exhibit wide tails, however without a directional dependence.

description: Image segmentation in the medical domain is a challenging field owing to poor resolution and limited contrast. The predominantly used conventional segmentation techniques and the thresholding methods suffer from limitations because of heavy dependence on user interactions. Uncertainties prevalent in an image cannot be captured by these techniques. The performance further deteriorates when the images are corrupted by noise, outliers and other artifacts. The objective of this paper is to develop an effective robust fuzzy C- means clustering for segmenting vertebral body from magnetic resonance image owing to its unsupervised form of learning. The motivation for this work is detection of spine geometry and proper localisation and labelling will enhance the diagnostic output of a physician. The method is compared with Otsu thresholding and K-means clustering to illustrate the robustness.The reference standard for validation was the annotated images from the radiologist, and the Dice coefficient and Hausdorff distance measures were used to evaluate the segmentation.

description: With recent technological developments within the field of power conditioning and the progressive
decrease of incentives for PV electricity in grid-connected markets, new operation modes for PV systems should be
explored beyond the traditional maximization of PV electricity feed-in. An example can be found in the domestic
sector, where the use of modern PV hybrid systems combined with efficient electrical appliances and demand side
management strategies can significantly enhance the PV value for the user. This paper presents an active demand
side management system able to displace the consumer’s load curve in response to local (PV hybrid system, user)
and external conditions (external grid). In this way, the consumer becomes an “active consumer” that can also
cooperate with others and the grid, increasing even more the PV value for the electrical system.

description: In the mammary gland Bcl-x is the most abundant cell survival factor from the Bcl-2 family. Since Bcl-x null mice die around day 12 of embryogenesis, the relevance of this protein in organ development and function is poorly understood. In erythroid cells bcl-x gene expression is controlled by cytokines and the transcription factor Stat5 (signal transducer and activator of transcription). However, we identified that bcl-x RNA levels in mammary tissue from prolactin receptor- and Stat5-null mice were indistinguishable from wild type mice. We have proposed that Bcl-x might control the survival of mammary epithelial cells throughout pregnancy, lactation, and the early stages of involution, and we have now tested this hypothesis through the conditional deletion of the bcl-x gene from mouse mammary epithelium. Conditional (floxed) bcl-x alleles were excised from alveolar cells during pregnancy using a Cre transgene under the control of the whey acidic protein gene promoter. Deletion of the bcl-x gene from the entire epithelial compartment (ducts and alveoli) was achieved by expressing Cre-recombinase under control of the mouse mammary tumor virus long terminal repeat. The absence of Bcl-x did not compromise proliferation and differentiation of mammary ductal and alveolar epithelial cells in virgin mice and during pregnancy and lactation. However, epithelial cell death and tissue remodeling were accelerated in the bcl-x conditional knockout mice during the first stage of involution. Concomitant deletion of the bax gene did not significantly modify the Bcl-x phenotype. Our results suggest that Bcl-x is not essential during mammopoiesis, but is critical for controlled apoptosis during the first phase of involution.

description: We report our recent effort for the extraction of resonance parameters (complex pole mass and residues etc.) associated with Lambda* and Sigma* hyperons. This was accomplished via a comprehensive partial-wave analysis of the data for K^- p --> barK N, pi Sigma, pi Lambda, eta Lambda, K Xi reactions from the thresholds up to W=2.1 GeV within a dynamical coupled-channels approach. The results suggest a possible existence of new narrow J^P=3/2^+ Λresonance with pole mass 1671^{+2}_{-8} -i(5^{+11}_{-2}) MeV, located close to the eta Lambda threshold. This resonance is found to be responsible for reproducing the data for K^-p --> eta Lambda differential cross sections near the threshold, and thus the data seem favor its existence. The extracted poles for J^P=1/2^- Lambda resonances below the barK N threshold, including Lambda(1405), are also presented.

description: Solar Thin Film has successfully brought the a-Si/a-Si tandem cell technology for ASITM (in
short ASI) modules to full production. Light-induced degradation of ASI modules is found to be reproducible
around 18 %. The temperature dependent LID factor was estimated from an experiment with cells to be 0.0028 K-1
which is consistent with the seasonal, temperature-driven LID variation of outdoor-exposed control modules. ASI
modules with thermally isolated rear side reveal a significant annealing effect; the energy yield is enhanced by
around 4 %. For long-term (14 and 16 years) monitored PV installations in Germany we demonstrate that the
initial, 2 years lasting stabilization phase is followed by a stable phase with a minor power decay of maximal 0.2 %
per year.

Interplay between strain, defect charge state and functionality in complex oxides

description: We use first-principles calculations to investigate the interplay between strain and the charge state of point defect impurities in complex oxides. Our work is motivated by recent interest in using defects as active elements to provide novel functionality in coherent epitaxial films. Using oxygen vacancies as model point defects, and CaMnO$_3$ and MnO as model materials, we calculate the changes in internal strain caused by changing the charge state of the vacancies, and conversely the effect of strain on charge-state stability. Our results show that the charge state is a degree of freedom that can be used to control the interaction of defects with strain and hence the concentration and location of defects in epitaxial films. We propose the use of field-effect gating to reversibly change the charge state of defects and hence the internal strain and corresponding strain-induced functionalities.

description: The Hedgehog (Hh) signaling pathway is essential for patterning many structures in vertebrates including the nervous system, chordamesoderm, limb and endodermal organs. In the sea urchin, a basal deuterostome, Hh signaling is shown to participate in organizing the mesoderm. At gastrulation the Hh ligand is expressed by the endoderm downstream of the Brachyury and FoxA transcription factors in the endomesoderm gene regulatory network. The co-receptors Patched (Ptc) and Smoothened (Smo) are expressed by the neighboring skeletogenic and non-skeletogenic mesoderm. Perturbations of Hh, Ptc and Smo cause embryos to develop with skeletal defects and inappropriate non-skeletogenic mesoderm patterning, although initial specification of mesoderm occurs without detectable abnormalities. Perturbations of the pathway caused late defects in skeletogenesis and in the non-skeletogenic mesoderm, including altered numbers of pigment and blastocoelar cells, randomized left-right asymmetry of coelomic pouches, and disorganized circumesophageal muscle causing an inability to swallow. Together the data support the requirement of Hh signaling in patterning each of the mesoderm subtypes in the sea urchin embryo. © 2009 Elsevier Inc. All rights reserved.

description: Consider a discrete valuation ring $R$ whose residue field is finite of cardinality at least $3$. For a finite torsion module, we consider transitive subsets $O$ under the action of the automorphism group of the module. We prove that the associated permutation representation on the complex vector space $C[O]$ is multiplicity free. This is achieved by obtaining a complete description of the transitive subsets of $O\times O$ under the diagonal action of the automorphism group.

description: We present a simple design to achieve bianisotropy at visible wavelengths: an ultrathin plasmonic grating made of a gold grating covered by a thin flat layer of gold. We show experimentally and through simulations that the grating exhibits magneto-electric coupling and features asymmetric reflection and absorption, all that with a device thickness of a tenth of the operating wavelength. We compared the spectral results and retrieved the effective material parameters of different polarizations and devices. We show that both asymmetry and strong coupling between the incoming light and the optically interacting surfaces are required for obtaining asymmetric optical behavior in metasurfaces.

description: Surface polaritons, e.g., surface plasmon polaritons, are invaluable tools in nanophotonics. However, considerable plasmon loss narrows the application regime of plasmonic devices. Here we reveal some general conditions for lossless surface polaritons to emerge at the interface of a gain and a loss media. The gain medium does not only compensate the energy loss, but also modifies surface wave oscillation mechanisms. A new type of surface polaritons induced by the sign switch of the imaginary part of the permittivity across the interface is discovered. The surface polaritons exhibit spin Hall effect due to spin-momentum locking and unique Berry phase. The spin Hall coefficient changes the sign across the parity-time symmetric limit and becomes quantized for perfect metal-dielectric interface and for dielectric-dielectric interface with very large permittivity contrast, carrying opposite topological numbers. Our study opens a new direction for manipulating light with surface polaritons in non-Hermitian optical systems.

description: This paper gives an overview on the latest progress of the French PHOTOSIL project towards an industrial
production. The PHOTOSIL consortium has been working for 6 years on a new innovative refining approach to produce
Upgraded Metallurgical Silicon (UMG) with a purity compatible with the specifications of the PV industry. The involved
refinement processes are based on physical techniques and run on an industrial pilot level with batch sizes of 100kg.
Two major directions for the evaluation of the quality of the PHOTOSIL UMG Silicon were pursued:
(i) a large quantity 1.3 tons of UMG Si was produced on the pilot facility using the standard PHOTOSIL purification
process to demonstrate the process stability in a continuous operation and its compatibility with the specifications
required by the PV industry. This UMG Silicon was used to demonstrate an installed module capacity of 100 kW using
multi-c Silicon solar cells from 100% PHOTOSIL UMG Silicon, which is currently under outdoor evaluation for energy
rating.
(ii) high quality UMG Silicon was purified with an improved process, to evaluate the ultimate performance potential in
terms of solar cell efficiencies compared to the performance of high purity polysilicon from the Siemens route.
The results of both evaluation routes as well as an economic evaluation allowed to start the next phase of the PHOTOSIL
project that will install by 2014 an improved and simplified 500 t/y industrial purification equipment.
A Scalable Low-Cost-UAV Traffic Network (uNet)

description: This article proposes a new Unmanned Aerial Vehicle (UAV) operation paradigm to enable a large number of relatively low-cost UAVs to fly beyond-line-of-sight without costly sensing and communication systems or substantial human intervention in individual UAV control. Under current free-flight-like paradigm, wherein a UAV can travel along any route as long as it avoids restricted airspace and altitudes. However, this requires expensive on-board sensing and communication as well as substantial human effort in order to ensure avoidance of obstacles and collisions. The increased cost serves as an impediment to the emergence and development of broader UAV applications. The main contribution of this work is to propose the use of pre-established route network for UAV traffic management, which allows: (i) pre- mapping of obstacles along the route network to reduce the onboard sensing requirements and the associated costs for avoiding such obstacles; and (ii) use of well-developed routing algorithms to select UAV schedules that avoid conflicts. Available GPS-based navigation can be used to fly the UAV along the selected route and time schedule with relatively low added cost, which therefore, reduces the barrier to entry into new UAV-applications market. Finally, this article proposes a new decoupling scheme for conflict-free transitions between edges of the route network at each node of the route network to reduce potential conflicts between UAVs and ensuing delays. A simulation example is used to illustrate the proposed uNet approach.

description: Energy is one of the central parameters required for human survival after food. “Knowledge is power” and
renewable energy plays increasingly important role to run knowledge-based society for sustainable social and economic
development. Out of these, solar photovoltaic (PV) energy system is a useful tool to run the knowledge based systems.
Apart from research and development, PV systems need suitable human capital for its successful penetration into every
nook and corner of the society. The main aim of the present paper is to address the quality and quantity of human capital
need in future to bring the solar PV power in the world electric power budget. Analyses on the chronology of PV power
systems indicated that PV would be equivalent to other conventional power sources by the year 2023. Proper
implementation of PV power systems needs three levels of human capital and these are i. Skilled technicians ii.
Experienced technologists and iii. Efficient executives. While the technicians would be involved in the installation,
operation, maintenance and monitoring of solar PV systems, technologists need to provide the basis for the liberalization
of PV systems and the executives need to develop its market, policy, planning and execution. Academic and research
institutions need to develop these types of human capital to match with future demand of the PV power systems. Market
and human capital are interdependent and the market for clean energy depends on issues like energy security, climate
change, fossil fuel depletion, new and novel technologies and environmentally conscious consumers. The future PV
market depends upon how powerful these forces are individually and collectively. Thus the PV communities need to
build up human capital as well as newer market to generate demand for human resource for better dissemination of PV power.

field is the heterojunction solar cell (HJT) which must not be subject to a temperature higher than 300° C in order to
avoid outdiffusion of atomic hydrogen. In this study, first the impact of a low temperature screen printing ink on the
characteristics of a HJT is investigated. In a second step, the compatibility of screen printed layers with cell connector
bonding is examined.

description: We consider a general class of three--state models where individuals hold one of two opposite opinions, or are neutral, and exchange opinions in generic pairwise interactions. We show that when opinions spread in a population where a fraction of individuals (zealots) maintain unshakably their opinion, one of four qualitatively distinct kinds of collective dynamics arise, depending on the specific rules governing the social interactions. Unsurprisingly, when their density is high, zealots drive the whole population to consensus on their opinion. For low densities a rich phase diagram emerges: a finite population of dissenters can survive and be the only stationary state or may need a critical mass or dissenters to be sustained; the critical mass may vanish or not as the density is reduced; the transition to the high density regime can be smooth or abrupt, and shows interesting hysteretic effects. For each choice of the interaction rules we calculate the critical density of zealots above which diverse opinions cannot survive.

description: Authentication of individuals via palmprint based biometric system is becoming very popular due to its reliability as it contains unique and stable features. In this paper, we present a novel approach for palmprint recognition and its representation. To extract the palm lines, local thresholding technique Niblack binarization algorithm is adopted. The endpoints of these lines are determined and a connection is created among them using the Delaunay triangulation thereby generating a distinct topological structure of each palmprint. Next, we extract different geometric as well as quantitative features from the triangles of the Delaunay triangulation that assist in identifying different individuals. To ensure that the proposed approach is invariant to rotation and scaling, features were made relative to topological and geometrical structure of the palmprint. The similarity of the two palmprints is computed using the weighted sum approach and compared with the k-nearest neighbor. The experimental results obtained reflect the effectiveness of the proposed approach to discriminate between different palmprint images and thus achieved a recognition rate of 90% over large databases.

description: A fast, non-destructive, non-contact and preparation free measurement method is introduced which is
capable of distinguishing between boron and gallium doped PV silicon bulk feedstock materials (slugs, ingots or
uneven shaped material pieces). The method consists of high-injection minority carrier lifetime measurement and
high intensity laser treatment. The microwave photoconductance decay method is applied as a high injection carrier
lifetime measurement.
The boron or gallium dopant species can be determined from the polarity of the carrier lifetime change caused by the
applied laser treatment sequence. All boron doped samples show negative carrier lifetime change, while the laser
treatment increases the lifetime of most gallium doped pieces. The negative lifetime change of boron doped silicon is
caused by the formation of boron-oxygen LID defects. Dissociation of iron-acceptor pairs is found to be responsible
for the lifetime increase in the gallium doped samples.
The dynamics of lifetime change caused by the laser treatment is discussed in detail, optical dissociation of irongallium
pairs is found to be much slower than in the case of iron-boron pairs, while light induced degradation shows
the expected dynamics.

description: These are the slides from the LIBER 2020 Workshop, ‘Hot RDM topics’ from a library perspective: what are the challenges and what role can library professionals play? Session Description: It’s been eight years since LIBER published 10 recommendations for libraries to get started with RDM. Since then, libraries have been actively involved in RDM, playing different roles and having various tasks. Notwithstanding the progress that libraries have made over the years, in RDM, libraries are largely faced with the same challenges, i.e. RDM as a strategic topic and developing adequate RDM services. What’s different and stands out today is a need for clarification of the role of the library and library professionals in solving the RDM challenges. This is the focus of the LIBER RDM workshop. In 2020, the LIBER RDM Working Group has prioritized 8 ‘hot RDM topics’ that require further guidance and articulation from the library perspective. The workshop will focus on these topics, i.e. data stewardship, FAIR data, data curation, data rights, DMP reviews, RDM training, implementing RDM policies, and engaging researchers. Brief pitches will be held for the hot topics, articulating the challenges and how libraries can move forward in these areas. We invite library data professionals, both newcomers and experts, to join us in an active workshop. The workshop participants will be challenged to discuss and review the deliverables of the LIBER RDM working group and to ‘brand’ the library in the field of
 RDM.

description: The goal of this research is to extract a large list or table from named entities and relations in a specific domain. A small set of a handful of instance relations is required as input from the user. The system exploits summaries from Google search engine as a source text. These instances are used to extract patterns. The output is a set of new entities and their relations. The results from four experiments show that precision and recall varies according to relation type. Precision ranges from 0.61 to 0.75 while recall ranges from 0.71 to 0.83. The best result is obtained for (player, club) relationship, 0.72 and 0.83 for precision and recall respectively.

description: The evaluation of the properties of a PV module in actual operating conditions is essential in order to
obtain a closer view of its real performance within a PV system generator. Particularly, the Yucatan Peninsula in the
Eastern of Mexico is a potential zone for PV applications because of the high availability of solar radiation over the
whole year. Thus, the Energy Laboratory of the University of Yucatan has been working on several projects to study the
solar resources and their potential application in PV systems. In this paper, a set of PV modules has been preliminary
evaluated in outdoor conditions. The performance of this modules related with the main environmental variables such as
solar radiation, ambient temperature and wind speed and direction has been analyzed over for a full year. This research
has produced useful information to optimize the design of PV system generators in the tropical of the Yucatan Peninsula.

Strongylocentrotus purpuratus

description: The foxa gene is an integral component of the endoderm specification subcircuit of the endomesoderm gene regulatory network in the Strongylocentrotus purpuratus embryo. Its transcripts become confined to veg2, then vegi endodermal territories, and, following gastrulation, throughout the gut. It is also expressed in the stomodeal ectoderm. gatae and otx genes provide input intol the pregastrular regulatory system of foxa, and Foxa represses its own transcription, resulting in an oscillatory temporal expression profile. Here, we report three separate essential functions of the foxa gene: it represses mesodermal fate in the veg2 endomesoderm; it is required in postgastrular development for the expression of gut-specific genes; and it is necessary for stomodaeum formation. If its expression is reduced by a morpholino, more endomesoderm cells become pigment and other mesenchymal cell types, less gut is specified, and the larva has no mouth. Experiments in which blastomere transplantation is combined with foxa MASO treatment demonstrate that, in the normal endoderm, a crucial role of Foxa is to repress gcm expression in response to a Notch signal, and hence to repress mesodermal fate. Chimeric recombination experiments in which veg2, veg1 or ectoderm cells contained foxa MASO show which region of foxa expression controls each of the three functions. These experiments show that the foxa gene is a component of three distinct embryonic gene regulatory networks.

description: Tensile tests of commercially available a-Si:H flexible solar cells were carried out under the xenon
lamp irradiation and mechanical damage accumulation was evaluated by AE technique. The open circuit voltage (Voc)
was also monitored during the test. Specimens were observed during and after the tests by a digital microscope and a
scanning electron microscope, respectively. AE signals were classified based on projected wavelet transform (PWT)
analysis so that AE signals corresponding to each failure mode could be identified. Onset of the degradation of Voc
was observed at the strain of ~0.9% and cumulative AE energy with frequency range of 600-800 kHz began to
increase. In addition, it was observed that TCO, a-Si:H and back electrode through-wall cracks perpendicular to
loading direction took place. As tensile strain increased to 11%, Voc decreased to ~0% and cumulative AE energy
with frequency range of 800-1000 kHz increased. Simultaneously, cracks perpendicular to loading direction in the
grid electrode were observed. Mechanical damage accumulation in a-Si:H solar cells under tensile strain was
successfully monitored by AE technique and corresponding damages were observed. Consequently, fundamental
implications for the characterization of durability of a-Si:H flexible solar cells were obtained in the present work.

description: High throughput mRNA expression profiling can be used to characterize the response of cell culture models to perturbations such as pharmacologic modulators and genetic perturbations. As profiling campaigns expand in scope, it is important to homogenize, summarize, and analyze the resulting data in a manner that captures significant biological signals in spite of various noise sources such as batch effects and stochastic variation. We used the L1000 platform for large-scale profiling of 978 genes, chosen to be representative of the genome as whole, across thousands of compound treatments. Here, a method is described that uses deep learning techniques to convert the expression changes of the landmark genes into a perturbation barcode that reveals important features of the underlying data, performing better than the raw data in revealing important biological insights. The barcode captures compound structure and target information, in addition to predicting a compound's high throughput screening promiscuity, to a higher degree than the original data measurements, indicating that the approach uncovers underlying factors of the expression data that are otherwise entangled or masked by noise. Furthermore, we demonstrate that visualizations derived from the perturbation barcode can be used to more sensitively assign functions to unknown compounds through a guilt-by-association approach, which we use to predict and experimentally validate the activity of compounds on the MAPK pathway. The demonstrated application of deep metric learning to large-scale chemical genetics projects highlights the utility of this and related approaches to the extraction of insights and testable hypotheses from big, sometimes noisy data.
