description: Let S be an infinite-dimensional manifold of all symplectic, or hyperkahler, structures on a compact manifold M, and $Diff_0$ the connected component of its diffeomorphism group. The quotient $S/\Diff_0$ is called the Teichmuller space of symplectic (or hyperkahler) structures on M. MBM classes on a hyperkahler manifold M are cohomology classes which can be represented by a minimal rational curve on a deformation of M. We determine the Teichmuller space of hyperkahler structures on a hyperkahler manifold, identifying any of its connected components with an open subset of the Grassmannian $SO(b_2-3,3)/SO(3)\times SO(b_2-3)$ consisting of all Beauville-Bogomolov positive 3-planes in $H^2(M, R)$ which are not orthogonal to any of the MBM classes. This is used to determine the Teichmuller space of symplectic structures of Kahler type on a hyperkahler manifold of maximal holonomy. We show that any connected component of this space is naturally identified with the space of cohomology classes $v\in H^2(M,\R)$ with $q(v,v)>0$, where $q$ is the Bogomolov-Beauville-Fujiki form on $H^2(M,\R)$.

description: Although 3D printing has become of increasing interest in the medical field and the demand for biodegradable polymers has rapidly developed, there are only a few additively manufactured, biodegradable implants on the market. Due to the thermosensitive behavior of such polymers, processing and sterilization of biodegradable implants and the side effects on their degradation have still not been sufficiently studied. The effects of fused filament fabrication (FFF) as well as low-temperature sterilization (H2O2 plasma and gamma radiation) on poly(p-dioxanone) (PPDO) and its degradation behavior were assessed. To quantify PPDO in vitro degradation the differently sterilized samples and a non-sterilized control group were immersed in phosphate buffered solution (PBS) over 4 weeks. Surface morphology, thermal and mechanical properties and molecular weight change were investigated directly after processing and at regular time intervals of immersion. Within this work, printability of thermosensitive PPDO via FFF was successfully demonstrated. Thermal characteristics, molecular weight (Mw) and inherent viscosity (IV) were not significantly affected by the printing process. Further, the investigation of the different sterilization methods presented that H2O2 plasma did not significantly harm the thermosensitive polymer whereas gamma radiation lowered Mw and IV statistically significant (p < 0.001). After being immersed in PBS, non-sterilized samples did not show any change of surface morphology, plasma-sterilized samples revealed small microcracks after two weeks while gamma-sterilized samples had already shown small microcracks directly after being radiated which further deteriorated over immersion duration. Mw and yield strength decreased for all samples. However, gamma-sterilized samples were affected the most. In addition, cell proliferation tests proved the cytocompatibility of degraded PPDO independently of the sterilization method. To conclude, we demonstrated that FFF and H2O2 plasma sterilization are well suited for processing thermosensitive, biodegradable PPDO. This research is meant to support the establishment of adequate production and sterilization methods for biodegradable implants.

description: A robust detection of defects and a reliable quality assurance is of great importance for the application of additive manufactured components, especially in heavily regulated industries such as the medical. Several techniques are currently used together for quality control and mostly reference parts are printed alongside for a subsequent destructive testing. Oftentimes, this elaborate quality assurance is hampering the widespread use of this particularly energy and resource-saving technology. By using micro computed tomography (µCT) scans, even complex components, such as individualized implants can be examined directly for defects. Typically, there are three types of defects in a powder bed fusion process, of which gas porosities and inclusions can be easily identified by means of µCT. Lack-of-fusion pores, on the other hand, which are caused by insufficient layer bonding in the printing process, are difficult to identify depending on the direction and their contrast to the solid material. As part of the publicly funded research project ENABL3D, this study examines methods for the optimized detection of these lack-of-fusion defects. For this purpose, different filtering and phase retrieval algorithms applied to projection and volume data in order to reduce noise, separate signal information and optimize the contrast of defects. Additionally, different reconstruction techniques and hardware setups are evaluated. The defects detected in this way are compared to the actual defects using microscopic cross-sectional images (micrographs) of test specimens. Thus, the potential of the evaluated algorithms is objectively compared and their parameters are optimized. It will be shown how phase contrast and other filtering methods have improved the detection of lack-of-fusion in additively manufactured metal components.

description: Rho GTPases are essential regulators of signaling networks emanating from many receptors involved in innate or adaptive immunity. The Rho family member RhoA controls cytoskeletal processes as well as the activity of transcription factors such as NF-κB, C/EBP and serum response factor. The multifaceted host cell activation triggered by Toll-like receptors (TLRs) in response to soluble and particulate microbial structures includes rapid stimulation of RhoA activity. RhoA acts downstream of TLR2 in HEK-TLR2 and monocytic THP-1 cells, but the signaling pathway connecting TLR2 and RhoA is still unknown. It is also not clear if RhoA activation is dependent on a certain TLR adapter. Using lung epithelial cells, we demonstrate TLR2- and TLR3-triggered recruitment and activation of RhoA at receptor-proximal cellular compartments. RhoA activity was dependent on TLR-mediated stimulation of Src family kinases. Both Src family kinases and RhoA were required for NF-κB activation, while RhoA was dispensable for type I interferon generation. These results suggest that RhoA plays a role downstream of MyD88-dependent and -independent TLR signaling and acts as a molecular switch downstream of TLR-Src initiated pathways.

description: The M 31 nova M31N 2008-12a was recently found to be a recurrent nova (RN) with a recurrence time of about 1 year. This is by far the fastest recurrence time scale of any known RNe. Our optical monitoring programme detected the predicted 2014 outburst of M31N 2008-12a in early October. We immediately initiated an X-ray/UV monitoring campaign with Swift to study the multiwavelength evolution of the outburst. We monitored M31N 2008-12a with daily Swift observations for 20 days after discovery, covering the entire supersoft X-ray source (SSS) phase. We detected SSS emission around day six after outburst. The SSS state lasted for approximately two weeks until about day 19. M31N 2008-12a was a bright X-ray source with a high blackbody temperature. The X-ray properties of this outburst were very similar to the 2013 eruption. Combined X-ray spectra show a fast rise and decline of the effective blackbody temperature. The short-term X-ray light curve showed strong, aperiodic variability which decreased significantly after about day 14. Overall, the X-ray properties of M31N 2008-12a are consistent with the average population properties of M 31 novae. The optical and X-ray light curves can be scaled uniformly to show similar time scales as those of the Galactic RNe U Sco or RS Oph. The SSS evolution time scales and effective temperatures are consistent with a high-mass WD. We predict the next outburst of M31N 2008-12a to occur in autumn 2015.

description: Folded supersymmetry (f-SUSY) stabilizes the weak scale against radiative corrections from the top sector via scalar partners whose gauge quantum numbers differ from their Standard Model counterparts. This non-trivial pairing of states can be realized in extra-dimensional theories with appropriate supersymmetry-breaking boundary conditions. We present a class of calculable f-SUSY models that are parametrized by a non-trivial twist in 5D boundary conditions and can accommodate the observed Higgs mass and couplings. Although the distinctive phenomenology associated with the novel folded states should provide strong evidence for this mechanism, the most stringent constraints are currently placed by conventional supersymmetry searches. These models remain minimally fine-tuned in light of LHC8 data and provide a range of both standard and exotic signatures accessible at LHC13.

description: This work demonstrates that viable human cells may be deposited in predefined geometries by an HP (HP inc.) TIPS (Thermal Inkjet Pipette System) jet-based bioprinter. The aim of these experiments is the incipient use of this bioprinter for printing human cells and verification of the cell viability following printing. Human embryonic kidney (HEK) cells were suspended in a modified cell medium to form a bioink-- a suspension of cells in a carrier solution for use in jet-based bioprinting. Cells were marked using Calcein dye, a cell-permeant dye used to determine cell viability via fluorescence. 1 cm x 1 cm squares were printed into 6-well plates using the jet-based bioprinter. Fluorescence images show a cell viability of over 90% immediately post-print. Printed cells reached approximately 70-100% confluence per well five days post printing. To offer the print more structural support, bioink was printed in alternating layers with a hydrogel, creating a cell-laden three-dimensional biological structure.

description: The development of methods to deal with the informative contents of the text units in the matching process is a major challenge in automatic summary evaluation systems that use fixed n-gram matching. The limitation causes inaccurate matching between units in a peer and reference summaries. The present study introduces a new Keyphrase based Summary Evaluator KpEval for evaluating automatic summaries. The KpEval relies on the keyphrases since they convey the most important concepts of a text. In the evaluation process, the keyphrases are used in their lemma form as the matching text unit. The system was applied to evaluate different summaries of Arabic multi-document data set presented at TAC2011. The results showed that the new evaluation technique correlates well with the known evaluation systems: Rouge1, Rouge2, RougeSU4, and AutoSummENG MeMoG. KpEval has the strongest correlation with AutoSummENG MeMoG, Pearson and spearman correlation coefficient measures are 0.8840, 0.9667 respectively.

description: Tissue-specific autoimmune diseases such as type 1 diabetes (T1D) are characterized by T cell-driven pathology. Administration of autoantigenic peptides provides a strategy to selectively target the pathogenic T cell response. Indeed, treatment with β cell peptides effectively prevents T1D in NOD mice. However, the efficacy of peptide immunotherapy generally wanes as β cell autoimmunity progresses and islet inflammation increases. With the goal of enhancing the efficacy of peptide immunotherapy, soluble (s)IAg7-Ig dimers covalently linked to β cell autoantigen-derived peptides were tested for the capacity to suppress late preclinical T1D. NOD female mice with established β cell autoimmunity were vaccinated i.v. with a short course of sIAg7-Ig dimers tethered to peptides derived from glutamic acid decarboxylase (GAD)65 (sIAg7-pGAD65). Treatment with sIAg7-pGAD65 dimers and the equivalent of only ~7 μg of native peptide effectively blocked the progression of insulitis and the development of diabetes. Furthermore, suppression of T1D was dependent on β cell-specific IL-10-secreting CD4+ T cells, although the frequency of GAD65-specific FoxP3-expressing CD4+ T cells was also increased in sIAg7-pGAD65 dimer vaccinated NOD mice. These results demonstrate that MHC class II-Ig dimer vaccination is a robust approach to suppress ongoing T cell-mediated autoimmunity, and may provide a superior strategy of adjuvant-free peptide-based immunotherapy to induce immunoregulatory T cells.

description: In Positron Emission Tomography (PET), radioactive phantoms are needed for calibration, characterization and quality assurance (QA) of the scanners. They can be simple structures such as flat radioactive sources, or hollow cylinders filled with liquid radioactive solutions. Image quality studies require more complex phantoms, which often consist of several fillable parts. To characterize the performance of high-resolution imaging devices, it is desirable to integrate tiny radioactive structures into the phantoms. Thanks to the latest and significant advances in 3D printing technology, it is now possible to print phantoms that include submillimeter structures. Since filling small structures with radioactive liquid is problematic (e.g., bubbles), direct printing with radioactive material would be preferable. Recently, phantoms printed with liquid resin mixed with 18F- Fludeoxyglucose (18F-FDG), a radiotracer for PET, with a half life of 110 min, were developed for clinical devices [1,2]. Due to their large size, these phantoms cannot be used for small animal PET. In this work, we have adapted this technique to allow for printing small structures. To achieve the necessary submillimeter resolution for the phantoms, we have adapted a reasonably priced desktop Digital Light Processing (DLP) 3D printer (Anycubic Photon Mono). The modifications included a reduced size resin tank (31mm3) and a smaller build plate (60x30mm2). The aim was to reduce the amount of required radioactive substances while preserving the activity concentration in the phantoms. Preliminary tests using 18F-FDG mixed to the resin were carried out with printed flat and point-like sources. The high resolution capability of the printer was not affected by the new resin mixture. The results show a homogeneous activity distribution within the phantoms. Additionally, more complex phantoms with regions containing different activity concentrations were printed and assembled. By combining active and non-active prints, we plan to create realistic phantoms, e.g. based on segmented anatomical data.

description: Any macroscopic deformation of a filamentous bundle is necessarily accompanied by local sliding and/or stretching of the constituent filaments. Yet the nature of the sliding friction between two aligned filaments interacting through multiple contacts remains largely unexplored. Here, by directly measuring the sliding forces between two bundled F-actin filaments, we show that these frictional forces are unexpectedly large, scale logarithmically with sliding velocity as in solid-like friction, and exhibit complex dependence on the filaments' overlap length. We also show that a reduction of the frictional force by orders of magnitude, associated with a transition from solid-like friction to Stokes' drag, can be induced by coating F-actin with polymeric brushes. Furthermore, we observe similar transitions in filamentous microtubules and bacterial flagella. Our findings demonstrate how altering a filament's elasticity, structure and interactions can be used to engineer interfilament friction and thus tune the properties of fibrous composite materials.

description: Generative design and especially topology optimization tools can greatly decrease production time and costs of additive manufacturing. Routine use of generative design workflows has rapidly increased over the last years in many different areas of mechanical design and additive manufacturing. Anatomically integrated applications have proven to be more challenging due to the difficulty of combining the high variability and complexity of anatomical structures with the necessary rigidity and simplicity of parameters for accurate topology optimization. As demonstration of this method three different support structures for the patient specific Lübeck Neuro-Angiography Simulator (Lu:NAS) were designed and SLA 3D printed. The topology optimization resulted in a 66 % decrease of resin usage and 39 % shorter printing time compared to the manually designed original geometry while retaining equivalent structural support of the anatomical model. Therefore, this method presents a simple and fast approach to effectively integrate topology optimization into a variety of anatomy-based design and 3D printing workflows, lowering associated costs significantly.

description: A first measurement is presented of exclusive photoproduction of $ρ^0$ mesons associated with leading neutrons at HERA. The data were taken with the H1 detector in the years $2006$ and $2007$ at a centre-of-mass energy of $\sqrt{s}=319$ GeV and correspond to an integrated luminosity of $1.16$ pb$^{-1}$. The $ρ^0$ mesons with transverse momenta $p_T<1$ GeV are reconstructed from their decays to charged pions, while leading neutrons carrying a large fraction of the incoming proton momentum, $x_L>0.35$, are detected in the Forward Neutron Calorimeter. The phase space of the measurement is defined by the photon virtuality $Q^2 < 2$ GeV$^2$, the total energy of the photon-proton system $20 < W_{γp} < 100$ GeV and the polar angle of the leading neutron $θ_n < 0.75$ mrad. The cross section of the reaction $γp \to ρ^0 n π^+$ is measured as a function of several variables. The data are interpreted in terms of a double peripheral process, involving pion exchange at the proton vertex followed by elastic photoproduction of a $ρ^0$ meson on the virtual pion. In the framework of one-pion-exchange dominance the elastic cross section of photon-pion scattering, $σ^{\rm el}(γπ^+ \to ρ^0π^+)$, is extracted. The value of this cross section indicates significant absorptive corrections for the exclusive reaction $γp\toρ^0 n π^+$.

description: The settlement and metamorphosis of the fully-developed larva of Conopeum seurati (Canu) has been observed. The early astogeny of colonies is described from preserved material. Comparisons have been made of the type of ancestrula and early astogeny of 15 membraniporine species. Three principal forms of budding have been seen. These correspond broadly to the accepted grouping of the majority of the species into three genera, namely, Membranipora, Electra and Conopeum, based on the characters of the later developed zooecia. Species of some other genera, e.g. Aspidelectra and Pyripora, may have, however, similar budding patterns.

description: Novel surface treatment for Additively Manufactured Polypropylene parts is presented in this work. The method uses green sustainable solvents to smooth, seal and remove semi-sintered powder particles from the surface. The surface smoothing produces parts that can be used in medical applications. Polypropylene (PP) is a non-polar, semi-crystalline thermoplastic polymer belonging to the polyolefin group. PP is the most used thermoplastic, and it is very cost effective as well. The properties of PP are dependent on its crystallinity, molecular weight, and stereochemistry (tacticity). PP has excellent chemical-resistant and water-impermeability properties. The recyclability of PP alongside its properties makes it suitable for many industrial applications [1] PP finds a lot of relevance in diverse aspects of medicine. It is used in the manufacture of medical products such as syringes, pouches, hospital disposables, test tubes, beakers, and pipettes. Drug-delivery systems, packaging and non-woven fabrics used in hospitals are made from PP. The water-impermeability property of PP makes it an attractive choice in the manufacture of biocompatible implants [2] One of the main hindrances to the use of 3D-printed PP parts in medical applications is due to the imperfections seen on the printed parts. Solvent smoothing of PP parts is very challenging; owning to the fact that PP is highly resistant to chemicals. However, identified solvents (such as carbon tetrachloride, benzene, xylene, etc.) used to smooth/dissolve PP parts have been identified as carcinogenic, neurotoxic, and environmentally unfriendly [3]. To this end, Additive Manufacturing Technologies Ltd (AMT) using its flagship 3D polymer post-processing equipment and expertise, have successfully demonstrated the smoothing of PP parts using some proprietary green solvents [4, 5]. These green solvents have low toxicities and are environmentally benign. The smoothed PP parts were seen to have better performance properties, both mechanically and aesthetically.

description: Naturally occurring regulatory T (nTreg) cells express Foxp3 and were originally discovered as immune suppressors critical for self-tolerance and immune homeostasis. Through yet-to-be-defined mechanisms, nTreg cells were recently shown to convert into proinflammatory cells. Particularly, attenuation of Foxp3 expression led to Th2 conversion of nTreg cells in vivo. In this paper, we demonstrated an nTreg-specific mechanism controlling their Th2 conversion. We found that wild-type nTreg cells expressing reduced levels of Foxp3 but not those expressing no Foxp3 produced the Th2 cytokine IL-4. Intriguingly, IL-4 production by converted nTreg cells is required for Th2 differentiation of coexisting naive CD4 T cells in vivo, suggesting that Th2 conversion of nTreg cells might be critical for directing Th2 immune responses. Th2 conversion of nTreg cells was not due to their inability to become Th1 cells, because IFN-γ was produced by Foxp3-low–expressing cells when IL-4/STAT-6 signaling was abrogated. Surprisingly, however, unlike naive CD4 T cells whose IL-4 production is dependent on STAT-6, Foxp3-low–expressing cells generated IL-4 independent of STAT-6, indicating an intrinsic mechanism that favors nTreg-to-Th2 differentiation. Indeed, compared with naive CD4 T cells, nTreg expressed elevated levels of GATA-3 independent of STAT-6. And GATA-3 was required for nTreg-to-Th2 conversion. Foxp3 may account for this GATA-3 upregulation in nTreg cells, because ectopic expression of Foxp3 preferentially promoted GATA-3 but not T-bet expression. Thus, we have identified an intrinsic mechanism that imposes a Th2/Th1 imbalance and predisposes Foxp3-expressing cells to IL-4 production independent of STAT-6 signaling.

description: The conventional manufacturing methods (such as solvent casting, particle leaching, freeze-drying, thermally induced phase separation, and gas foaming [1]) are not applicable to creating pre-determined complex anatomical geometries, and utilization of polymer-ceramic material composition with these types of manufacturing methods is a challenge. Nevertheless, additive manufacturing methods have been introduced in the medical field and one of such methods, Fused Deposition Modelling (FDM)- pneumatic method (Allevi 1 by 3D Systems) is provided as a cutting-edge solution in terms of producibility of such complex geometries with referred composite materials. In particular, Poly lactic co glycol acid (PLGA): micro/nano Hydroxyapatite (m/n HAp) weight ratio, printing parameters, physical characterization of constructs after printing, and in vitro or in vivo tests were examined in order to understand their compatibility with bone tissue engineering applications [1],[2],[3]. These applications have been provided a starting point to give a solution for pediatric craniomaxillofacial implant treatment. Therefore, the method developed in this paper is dedicated to children, as such craniomaxillofacial (CMF) implants do not hinder the physical growth of these developing children. Moreover, the lattice geometries have been introduced last decades as a new scaffold design [4]. In this study, one of the Triply Periodic Minimal Surface Lattice types, Gyroid has been chosen both for osteointegration and self-supporting features for biological response and producibility respectively. In this article, three different HAp weight percentages within the final PLGA/m/nHAp composite material (10, 20, and 30 %, w/w) and the producibility of innovative patient-specific geometry design with these materials will be discussed.

description: В 2004 и 2007 гг. 12 стран Центральной и Восточной Европы присоединились к Европейскому союзу, благодаря чему процесс перехода от бывшей социалистической системы к рыночной форме хозяйства формально подошел к концу. Несмотря на длительную подготовку стран, вступление в Европейский союз было как шаг в неизвестную территорию. Ожидаемые последствия расширения в сельском хозяйстве в 15 странах ЕС и в странах-кандидатах были одной из самых обсуждаемых тем. Десятая годовщина присоединения это хорошая возможность для анализа и оценки развития сельского хозяйства новых государств-членов ЕС в свете последних имеющихся данных. Результаты исследования свидетельствуют о том, что Польша и страны Балтии могут рассматриваться как лидеры вступления в ЕС в сельском хозяйстве, в то время как Румыния, Болгария и Словения использовали свой потенциал в наименьшей степени. Результаты также показывают, что сосредоточение на высокой добавленной стоимости сельскохозяйственной продукцией оказалось хорошей стратегией для достижения развития в аграрной сфере, а те страны, которые были сосредоточены на производстве аграрно-продовольственного сырья, оказались отстающими. Эти результаты могут также быть полезными и для других стран, испытывающих аналогичные проблемы интеграции, как и новые государства-члены Европейского союза.In 2004 and 2007, 12 countries of Central and Eastern Europe acceded to the European Union, by which the transition process from the former socialist system to a market based agriculture formally came to an end. Despite the long-lasting preparations of countries, accession to the European Union was somehow a step into unknown territory. The expected impacts of enlargement in agriculture both in EU15 and in the candidate countries have been one of the most debated areas. The tenth anniversary of accession is a good opportunity for stocktaking and assessing the agricultural developments of the New Member States (NMS) in light of the latest data available. Results suggest that Poland and the Baltic countries can be treated as the winners of EU accession in agriculture, while Romania, Bulgaria and Slovenia proved to have used their potentials to the least. Results also suggest that focusing on high value added agri-food products proved to be a good strategy to reach development in the agriculture sector, while those countries concentrating on the production of agri-food raw materials turned out to be lagged behind. These results might also be useful for other countries experiencing similar integration issues like the NMS.

description: Let G be a finite abelian group. This paper is concerned with nonnegative functions on G that are sparse with respect to the Fourier basis. We establish combinatorial conditions on subsets S and T of Fourier basis elements under which nonnegative functions with Fourier support S are sums of squares of functions with Fourier support T. Our combinatorial condition involves constructing a chordal cover of a graph related to G and S (the Cayley graph Cay($\hat{G}$,S)) with maximal cliques related to T. Our result relies on two main ingredients: the decomposition of sparse positive semidefinite matrices with a chordal sparsity pattern, as well as a simple but key observation exploiting the structure of the Fourier basis elements of G. We apply our general result to two examples. First, in the case where $G = \mathbb{Z}_2^n$, by constructing a particular chordal cover of the half-cube graph, we prove that any nonnegative quadratic form in n binary variables is a sum of squares of functions of degree at most $\lceil n/2 \rceil$, establishing a conjecture of Laurent. Second, we consider nonnegative functions of degree d on $\mathbb{Z}_N$ (when d divides N). By constructing a particular chordal cover of the d'th power of the N-cycle, we prove that any such function is a sum of squares of functions with at most $3d\log(N/d)$ nonzero Fourier coefficients. Dually this shows that a certain cyclic polytope in $\mathbb{R}^{2d}$ with N vertices can be expressed as a projection of a section of the cone of psd matrices of size $3d\log(N/d)$. Putting $N=d^2$ gives a family of polytopes $P_d \subset \mathbb{R}^{2d}$ with LP extension complexity $\text{xc}_{LP}(P_d) = Ω(d^2)$ and SDP extension complexity $\text{xc}_{PSD}(P_d) = O(d\log(d))$. To the best of our knowledge, this is the first explicit family of polytopes in increasing dimensions where $\text{xc}_{PSD}(P_d) = o(\text{xc}_{LP}(P_d))$.
