description: We study the online influence maximization problem in social networks under the independent cascade model. Specifically, we aim to learn the set of "best influencers" in a social network online while repeatedly interacting with it. We address the challenges of (i) combinatorial action space, since the number of feasible influencer sets grows exponentially with the maximum number of influencers, and (ii) limited feedback, since only the influenced portion of the network is observed. Under a stochastic semi-bandit feedback, we propose and analyze IMLinUCB, a computationally efficient UCB-based algorithm. Our bounds on the cumulative regret are polynomial in all quantities of interest, achieve near-optimal dependence on the number of interactions and reflect the topology of the network and the activation probabilities of its edges, thereby giving insights on the problem complexity. To the best of our knowledge, these are the first such results. Our experiments show that in several representative graph topologies, the regret of IMLinUCB scales as suggested by our upper bounds. IMLinUCB permits linear generalization and thus is both statistically and computationally suitable for large-scale problems. Our experiments also show that IMLinUCB with linear generalization can lead to low regret in real-world online influence maximization.

description: Phenomenological nonequilibrium thermodynamics describes how fluxes of conserved quantities such as matter, energy and charge flow from outer reservoirs across a system, and how they irreversibly degrade from one form to another. Stochastic thermodynamics is formulated in terms of probability fluxes circulating in the system's configuration space. The consistency of the two frameworks is granted by the condition of local detailed balance, which specifies the amount of physical quantities exchanged with the reservoirs during single transitions between configurations. We demonstrate that the topology of the configuration space crucially determines the number of independent thermodynamic affinities (forces) that the reservoirs generate across the system, and provide a general algorithm that produces the fundamental affinities and their conjugate currents contributing to the total dissipation, based on the interplay between macroscopic conservations laws for the currents and microscopic symmetries of the affinities.

description: Histogenetisch bedingte Sternmusterungen an Petalen treten in verschiedenen Pflanzengattungen auf und konnten bei Camellia, Pelargonium, Phlox, Rhododendron, Saintpaulia und Verbena nachgewiesen werden, sie sind aber auch bei Myosotis und Petunia bekannt. Die Sternmusterungen entstehen bei den untersuchten Sorten durch Anthocyandefektmutation in einer bestimmten Sproßscheitelschicht und den abstammenden Geweben, in Abhängigkeit von der gewebespezifischen Farbstoffbildung im Blütenblatt, dem Wirken der Partnerinduktion von anthocyanintaktem auf anthocyandefektes Gewebe (Induktion der Anthocyansynthese) und der L1-Beteiligung an der Mesophyllbildung des Blütenblattrandes. Fünf unterschiedliche Typen der histogenetisch bedingten Sternmusterbildung in der Petalenfärbung unter Berücksichtigung dieser Charakteristika konnten gefunden werden.
description: Histogenetically determined pinwheel patterns in petals exist in various genera of plants. Such patterns have been proved in Camellia, Pelargonium, Phlox, Rhododendron, Saintpaulia and Verbena, and are also known in Myosotis and Petunia. Pinwheel patterns occur by mutation in a defined layer of the apex and ist originated tissues. Its intensity is affected by presence of pigmentation in specific tissues of the petal and the existance and level of partner- induction (induction of anthocyanin synthesis from anthocyan-intact to anthocyan-defect tissue), and the participation of L1 (layer one of the apex) on the formation of mesophyll in the margin of the petal. Five different types of the histogenetically determined formation of pinwheel patterns were found according to the above mentioned conditions. In addtion, some other types can exist when more than two layers of the apex and their derived tissues form the petals (perhaps in Camellia) and layer 2 and 3 are different in their genotypes.

description: Poland's overall economic, political and social situation is improving. However, in the realm of trust, the Polish press may be judging their countrymen and women too harshly. I argue that there is a disconnect between contemporary popular Polish press articles highlighting the extremely distrustful nature of Polish society and the cross-national data which prove that Poles are in the middle of the pack in comparison to other Eastern European countries when it comes to social trust. This disconnect, which I call the distrust paradox, is revealed in this study by comparing online media and data sources. This distrust paradox is not present in the academic discourse on Poland and other transitioning societies. Poland's turbulent history accounts for a low level of trust in government, institutions, and other citizens, by Western standards. The press articles may be exaggerated, since optimism, societal trust, and general life satisfaction are all on the rise.

description: Die Langlebigkeit reifer periphärer B Zellen ist abhängig von mindestens zwei Überlebenssignalen, einem tonischen Signal, welches vom B Zellrezeptor ausgeht und dem Zytokin B Zell aktivierender Faktor der TNF-Familie (BAFF). BAFF fördert nicht nur das Überleben von reifen B Zellen, sondern kontrolliert auch deren Funktionstüchtigkeit, indem es vielschichtige physiologische Prozesse wie Zellwachstum und –metabolismus, Energiehaushalt und Eintritt in den Zellzyklus reguliert. Zwei BAFF-induzierte molekulare Mechanismen, zum einen die Aktivierung des Akt Signaltransduktionsweges sowie die erhöhte Expression der onkogenen kinase Pim-2 zum anderen, führen zu Veränderungen in Effektorproteinen welche in der Lage sind diese physiologischen Zellveränderungen auszulösen. Die BAFF-induzierte Aktivierung von Akt hängt von der klassischen Proteinkinase C (PKC) beta ab und sowohl PKC beta-defiziente B Zellen als auch Mäuse zeigen Anzeichen von Unsensitivität gegenüber BAFF-Stimulation. Die Proteintyrosinkinase Syk spielt eine Rolle während der frühen B Zellentwicklung und wird in reifen B Zellen durch Stimulation des B Zellrezeptors aktiviert. Induzierbare Inaktivierung von Syk in Mäusen führt zum Verschwinden reifer B Zellen aus den periphären lymphoiden Organen, was auf eine unverzichtbare Funktion von Syk in der Vermittlung des tonischen B Zellrezeptorsignals schliessen läßt.
description: The maintenance of mature peripheral B cells depends on at least two survival cues, tonic signaling from the B cell receptor (BCR) complex and the extracellular cytokine B cell activating factor of the TNF family (BAFF). In addition to enhancing viability, BAFF controls the functional efficiency of the peripheral B cell pool by regulating complex physiological processes including cell growth, metabolism, energy homeostasis and entry into the cell cycle. BAFF-mediated induction of two molecular mechanisms, namely activation of the Akt signal transduction pathway and upregulation of the oncogenic kinase Pim-2 results in the modification of effector proteins including transcription factors and regulators of protein synthesis which are capable of executing the observed cellular physiological changes. The classic protein kinase C beta is instrumental in BAFF-induced Akt-activation and PKC beta-deficient B cells and mice show signs of partial refractiveness to BAFF. The protein tyrosine kinase Syk plays a role in early B cell development and is activated in mature B cells by immunogenic BCR-stimulation. Inducible ablation of Syk in mice results in the loss mature B cells from the peripheral lymphoid organs and reveals an indispensable function for Syk in tonic BCR survival signaling.

description: Cisterna Magna blood injection model is a well established method in research to study of subarachnoidal hemorrhage (SAH). Blood injection into the Cisterna Magna displays one well known and commonly used technique which is used in small animals like mice with the advantage of a low mortality rate of this technique compared with other. With this review we want to find methodological parameters who might disturb heterogeneity and might influence outcome of the experiments such as mortality rate, affected area, Timepoint of EBI and DBI. We want to analyse keyfactors which might have an impact for outcome and find a consensus to reduce needed animal numbers in experiments in the sense of the 3-R principles (replace, reduce and refine).

description: We generalise gauge theory on a graph so that the gauge group becomes a finite-dimensional ribbon Hopf algebra, the graph becomes a ribbon graph, and gauge-theoretic concepts such as connections, gauge transformations and observables are replaced by linearised analogues. Starting from physical considerations, we derive an axiomatic definition of Hopf-algebra gauge theory, including locality conditions under which the theory for a general ribbon graph can be assembled from local data in the neighbourhood of each vertex. For a vertex neighbourhood with n incoming edge ends, the algebra of non-commutative "functions" of connections is dual to a two-sided twist deformation of the n-fold tensor power of the gauge Hopf algebra. We show these algebras assemble to give an algebra of functions and gauge-invariant subalgebra of "observables" that coincide with those obtained in the combinatorial quantisation of Chern-Simons theory, thus providing an axiomatic derivation of the latter. We then discuss holonomy in a Hopf algebra gauge theory and show that for semisimple Hopf algebras this gives, for each path in the embedded graph, a map from connections into the gauge Hopf algebra, depending functorially on the path. Curvatures -- holonomies around the faces canonically associated to the ribbon graph -- then correspond to central elements of the algebra of observables, and define a set of commuting projectors onto the subalgebra of observables on flat connections. The algebras of observables for all connections or for flat connections are topological invariants, depending only on the topology, respectively, of the punctured or closed surface canonically obtained by gluing annuli or discs along edges of the ribbon graph.

description: The quest for colorful components (connected components where each color is associated with at most one vertex) inside a vertex-colored graph has been widely considered in the last ten years. Here we consider two variants, Minimum Colorful Components (MCC) and Maximum Edges in transitive Closure (MEC), introduced in 2011 in the context of orthology gene identification in bioinformatics. The input of both MCC and MEC is a vertex-colored graph. MCC asks for the removal of a subset of edges, so that the resulting graph is partitioned in the minimum number of colorful connected components; MEC asks for the removal of a subset of edges, so that the resulting graph is partitioned in colorful connected components and the number of edges in the transitive closure of such a graph is maximized. We study the parameterized and approximation complexity of MCC and MEC, for general and restricted instances. For MCC on trees we show that the problem is basically equivalent to Minimum Cut on Trees, thus MCC is not approximable within factor $1.36 - \varepsilon$, it is fixed-parameter tractable and it admits a poly-kernel (when the parameter is the number of colorful components). Moreover, we show that MCC, while it is polynomial time solvable on paths, it is NP-hard even for graphs with constant distance to disjoint paths number. Then we consider the parameterized complexity of MEC when parameterized by the number $k$ of edges in the transitive closure of a solution (the graph obtained by removing edges so that it is partitioned in colorful connected components). We give a fixed-parameter algorithm for MEC paramterized by $k$ and, when the input graph is a tree, we give a poly-kernel.
Comparative Cytotoxicity of Drinking Water Disinfection By-Product Mixtures Produced During Chlorination and Chloramination

Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Chlorinated and chloraminated waters containing characterized natural organic matter (NOM) were compared on the basis of cytotoxicity, disinfection by-product (DBP), and total organic halogen (TOX) levels. Cytotoxicity was evaluated using a growth inhibition assay (GIA) in NCM460 human colon cells. Without adding iodide or nitrate or using medium pressure ultraviolet (UV) pretreatment, the chlorinated water was more cytotoxic than the chloraminated water. At elevated iodide levels and using pretreatment with medium pressure UV, the chloraminated water was the most cytotoxic of all disinfected samples evaluated. This is likely due to the formation of iodinated DBPs, possibly enhanced by degradation of the NOM with UV but present at levels below detection of the analytical methods used. This current research shows that the GIA is able to detect these differential cytotoxic responses, and can provide more insight into changes in water quality than DBP and TOX measurements alone.

description: Ultracold atoms are an ideal platform to study strongly correlated phases of matter in and out of equilibrium. Much of the experimental progress in this field crucially relies on the control of the contact interaction between two atoms. Control of strong long-range interactions between distant ground state atoms has remained a long standing goal, opening the path towards the study of fundamentally new quantum many-body systems including frustrated or topological magnets and supersolids. Optical dressing of ground state atoms by near-resonant laser coupling to Rydberg states has been proposed as a versatile method to engineer such interactions. However, up to now the great potential of this approach for interaction control in a many-body setting has eluded experimental confirmation. Here we report the realisation of coherent Rydberg-dressing in an ultracold atomic lattice gas and directly probe the induced interaction potential using an interferometric technique with single atom sensitivity. We use this approach to implement a two-dimensional synthetic spin lattice and demonstrate its versatility by tuning the range and anisotropy of the effective spin interactions. Our measurements are in remarkable agreement with exact solutions of the many-body dynamics, providing further evidence for the high degree of accurate interaction control in these systems. Finally, we identify a collective many-body decay process, and discuss possible routes to overcome this current limitation of coherence times. Our work marks the first step towards the use of laser-controlled Rydberg interactions for the study of exotic quantum magnets in optical lattices.

Η ωμική ζώνη αποτελείται δεξιά και αριστερά από δύο οστά, μπροστά μεν από την κλείδα, πίσω δε από την ωμοπλάτη. Το βραχιόνιο οστούν είναι το επιμηκέστερο από τα οστά του άνω άκρου, προς τα άνω συντάσσεται με την ωμοπλάτη μέσω της διάρθρωσης του ώμου και προς τα κάτω με τα δύο οστά του πήχη, την κερκίδα εκ των έξω και την ωλένη εκ των έσω, μέσω της διάρθρωσης του αγκώνος. Ο σκελετός της άκρας χείρας είναι το τελικό κομμάτι του άνω άκρου και αποτελείται από 27 οστά, τα οστά του καρπού, των μετακαρπίων και των δακτύλων, δηλαδή τις φάλαγγες. Κάθε οστούν φέρει τα δικά του μορφώματα πάνω στα οποία καταφύονται μαλακά μόρια, τα οποία συγκροτούν τον σκελετό σταθερό στη σωστή του ανατομική θέση. Το κάθε οστό μπορεί να παρουσιάσει με διαφορετική συχνότητα ανατομικές παραλλαγές και κατ’ επέκταση διαφορετική χωροδιάταξη ιστών, γεγονός το οποίο αποτελεί πρόκληση για τον ανατόμο-χειρουργό. Ως εκ τούτου η άριστη γνώση της ανατομίας κρίνεται απαραίτητη από τους σύγχρονους χειρουργούς για την αποφυγή χειρουργικών επιπλοκών. Σκοπός της παρούσας συστηματικής ανασκόπησης είναι, η συγκέντρωση και καταγραφή κάθε ανατομικής παραλλαγής-ανωμαλίας που έχει περιγραφεί στην βιβλιογραφία, καθώς και η κλινική συσχέτιση που πιθανώς έχει η κάθε ανατομική παραλλαγή ξεχωριστά.
description: The upper limb skeleton consists of four parts: I) the skeleton of the shoulder zone or shoulder, a mechanism for hanging and connecting the upper limb II) the humeral bone or humerus III) the antibrachium or forearm and IV) the hand. The shoulder zone consists of 2 bones in each side: ventral is the clavicle and dorsal is the scapula. The humerus is the longest upper limb bone, connected proximally with the scapula through the shoulder joint and distally through the elbow joint with the 2 antibrachial bones: the ulna medially and the radius laterally. The hand is the most distal part of the upper limb and comprises 26 bones: carpal, metacarpal and phalanges. Every bone has its morphological features where soft tissue is inserted, which keeps the skeleton in its anatomical position. Each bone can present with anatomical variances in different incidences, thus, resulting in different tissue topography, confusing the anatomist or surgeon. Perfect knowledge of variance anatomy is imperative for modern surgeons to avoid surgical complications. This systematic review aims to collect and record every anatomical variance or anomaly reported in the literature and to explore clinical correlations for each anatomical variance.

description: Apostle Paul's teaching in the first letter of Corinthians, and his exhortation to the women of Corinth to wear head covering, was the trigger for the completion of this thesis. The research focused on the causes that led the Apostle of the Nations to this exhortation, through a mosaic of opinions, which opens wider horizons and at the same time directs a radical revision of the perceptions of the relations between the two sexes. Apostle Paul had the ability to understand the essence and the characteristics as well, that a Christian community should have, shaping the context in which Christians are called to surround their lives. The purpose is for Orthodox Christians to understand the role of both sexes, both within the church and within the family. The work brings out the essence of the teaching of St. Paul through the presentation of examples, the importance of which leads them to the essential conclusion of our Faith. Jesus Christ is the head of all of us and leads us to real freedom.

description: The gravitational-wave signal GW150914 was first identified on Sept 14 2015 by searches for short-duration gravitational-wave transients. These searches identify time-correlated transients in multiple detectors with minimal assumptions aboutthe signal morphology, allowing them to be sensitive to gravitational waves emitted by a wide range of sources including binary black-hole mergers. Over the observational period from September 12th to October 20th 2015, these transient searches were sensitive to binary black-hole mergers similar to GW150914 to an average distance of $\sim 600$ Mpc. In this paper, we describe the analyses that first detected GW150914 as well as the parameter estimation and waveform reconstruction techniques that initially identified GW150914 as the merger of two black holes. We find that the reconstructed waveform is consistent with the signal from a binary black-hole merger with a chirp mass of $\sim 30 \, M_\odot$ and a total mass before merger of $\sim 70 \, M_\odot$ in the detector frame.

Contesting Images: Representations of the Modern Woman in the German Illustrated Press, 1924-1933

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Images of the Modern Woman emerged during the interwar years alongside the expansion of the illustrated press, a new form of mass media, which reached a broad social strata. Thus far, scholars have concentrated on this consumer orientated image without acknowledging the tensions and contestation between differing conceptions of femininity in the broad and changing political spectrum of postwar Germany and the nuanced differences found in the visual and textual representations produced in a wide range of illustrated magazines. Questioning the dominant depiction of the New Woman, I argue that illustrated magazines of different political backgrounds incorporated, modified and emphasized different elements of the Modern Woman and thus presented conflicting constructions of femininity while locating modernity within the female body.

description: We present a unified evolution of the universe from very early times until the present epoch by including both the leading local correction $R^2$ and the leading non-local term $R\frac{1}{\square^2}R$ to the classical gravitational action. We find that the inflationary phase driven by $R^2$ term gracefully exits in a transitory regime characterized by coherent oscillations of the Hubble parameter. The universe then naturally enters into a radiation dominated epoch followed by a matter dominated era. At sufficiently late times after radiation-matter equality, the non-local term starts to dominate inducing an accelerated expansion of the universe at the present epoch. We further exhibit the fact that both the leading local and non-local terms can be obtained within the covariant effective field theory of gravity. This scenario thus provides a unified picture of inflation and dark energy in a single framework by means of a purely gravitational action without the usual need of a scalar field.

Overview

Eunha Park thought she was getting another chance at life when she awoke in the world of a novel. The only problem? Raeliana McMillan, the character she was reborn as, is fated to be killed by her fiancé! For the sake of her survival, she comes up with an idea—get into a fake marriage with a man more powerful than her groom-to-be. But when that protection comes in the form of Noah Wynknight, the duke with a warm smile and cold heart, Raeliana realizes she might be a bit in over her head…She’s going to regret this plan, isn’t she?

description: Το Green Deal (Πράσινο Σύμφωνο για την Ενέργεια) μαζί με το CSS (Chemical Strategy for Sustainability), είναι τα πλαίσια που προωθεί η Ευρωπαϊκή Ένωση, με σκοπό την αντιμετώπιση της κλιματικής αλλαγής και την προώθηση μιας πιο κυκλικής οικονομίας και χρήσης βιώσιμων χημικών. Σύμφωνα με το CSS, στόχος είναι η προώθηση της μετάβασης σε προϊόντα πιο ασφαλή και βιώσιμα (Safe-and-Sustainable by Design - SSbD). Για να επιτευχθεί μια τέτοια μετάβαση με επιτυχία, πρέπει να οριστούν τα κατάλληλα κριτήρια, τα οποία θα πρέπει να χρησιμοποιούνται από τα διάφορα υπολογιστικά εργαλεία που χρησιμοποιούνται για την αξιολόγηση των προϊόντων. Σε αυτή την εργασία, πραγματοποιήθηκε μια έρευνα για τις αρχές της βιωσιμότητας, της κυκλικής οικονομίας και της SSbD λογικής, και μελετήθηκαν τα κριτήρια, τα οποία πρέπει να ικανοποιούνται, ως προς τις πτυχές της ασφάλειας, του περιβάλλοντος, της κοινωνίας και της οικονομίας, για την αξιολόγηση από τα διάφορα υπολογιστικά προγράμματα ενός προϊόντος ως SSbD.
description: The Green Deal (Green Pact for Energy) along with the CSS (Chemical Strategy for Sustainability), are the frameworks promoted by the European Union, with the aim of tackling climate change and promoting a more circular economy and the use of more sustainable chemicals. According to CSS, the goal is to promote the transition to safer and more sustainable products (Safe-and-Sustainable by Design-SSbD). To achieve such a transition successfully, appropriate criteria must be defined, which should be used by the various computational tools used to evaluate products. In this work, research was carried out on the principles of sustainability, circular economy and SSbD logic, and the criteria, which must be satisfied, in terms of safety, environmental, social and economic aspects, were studied for the assessment of a product as SSbD, by the various computational tools.

description: Kelvin-Helmholtz Instabilities (KHI) along contact discontinuities in galaxy clusters have been used to constrain the strength of magnetic fields in galaxy clusters, following the assumption that, as magnetic field lines drape around the interface between the cold and hot phases, their magnetic tension resists the growth of perturbations. This has been observed in simulations of rigid objects moving through magnetised media and sloshing galaxy clusters, and then applied in interpreting observations of merger cold fronts. Using a suite of MHD simulations of binary cluster mergers, we show that even magnetic field strengths stronger than yet observed ($β= P_{\rm th}/P_B = 50$) show visible KHI features. This is because our initial magnetic field is tangled, producing Alfven waves and associated velocity fluctuations in the ICM; stronger initial fields therefore seed larger fluctuations, so that even a reduced growth rate due to magnetic tension produces a significant KHI. The net result is that a stronger initial magnetic field produces more dramatic fluctuations in surface brightness and temperature, not the other way around. We show that this is hard to distinguish from the evolution of turbulent perturbations of the same initial magnitude. Therefore, in order to use observations of KHI in the ICM to infer magnetic field strengths by comparing to idealized simulations, the perturbations which seed the KHI must be well-understood and (if possible) carefully controlled.

description: Loop-level scattering amplitudes for massless particles have singularities in regions where tree amplitudes are perfectly smooth. For example, a $2\to4$ gluon scattering process has a singularity in which each incoming gluon splits into a pair of gluons, followed by a pair of $2\to2$ collisions between the gluon pairs. This singularity mimics double parton scattering because it occurs when the transverse momentum of a pair of outgoing gluons vanishes. The singularity is logarithmic at fixed order in perturbation theory. We exploit the duality between scattering amplitudes and polygonal Wilson loops to study six-point amplitudes in this limit to high loop order in planar ${\cal N}=4$ super-Yang-Mills theory. The singular configuration corresponds to the limit in which a hexagonal Wilson loop develops a self-crossing. The singular terms are governed by an evolution equation, in which the hexagon mixes into a pair of boxes; the mixing back is suppressed in the planar (large $N_c$) limit. Because the kinematic dependence of the box Wilson loops is dictated by (dual) conformal invariance, the complete kinematic dependence of the singular terms for the self-crossing hexagon on the one nonsingular variable is determined to all loop orders. The complete logarithmic dependence on the singular variable can be obtained through nine loops, up to a couple of constants, using a correspondence with the multi-Regge limit. As a byproduct, we obtain a simple formula for the leading logs to all loop orders. We also show that, although the MHV six-gluon amplitude is singular, remarkably, the transcendental functions entering the non-MHV amplitude are finite in the same limit, at least through four loops.

description: Στην παρούσα εργασία ελέγχθηκε η βραχυπρόθεσμη επίδραση τριών φυτοφαρμάκων: του εντομοκτόνου karate Zeon με δραστική ουσία την λ-κυαλοθρίνη, και των μυκητοκτόνων Score και Ortiva με δραστικές ουσίες τις διφενοκοναζόλη και αζοξυστροβίνη, αντίστοιχα. Μελετήθηκε η επίδραση τους μεμονωμένα αλλά και σε συνδυασμό στη δομή της κοινότητας των μικροβίων και των νηματωδών του εδάφους. . Για την παρούσα μελέτη εγκαταστάθηκαν 20 πειραματικές επιφάνειες εμβαδού 5 X 5 = 25m2 η κάθε μία. Συνολικά εφαρμόστηκαν 4 διαφορετικοί χειρισμοί με 5 επαναλήψεις για τον καθένα: καμία παρέμβαση (Μάρτυρας), διαφυλλικός ψεκασμός με εντομοκτόνο, διαφυλλικός ψεκασμός με τα 2 μυκητοκτόνα και ψεκασμός με συνδυασμό μυκητοκτόνων και εντομοκτόνου. Η πρώτη δειγματοληψία έγινε πριν την εφαρμογή των χειρισμών (Ιούνιος 2021), κατόπιν ακολούθησαν οι ψεκασμοί που πραγματοποιήθηκαν εις τριπλούν με ενδιάμεσο διάστημα τις 15 μέρες, και η δεύτερη δειγματοληψία πραγματοποιήθηκε τρεις μήνες μετά την τελευταία εφαρμογή. Εδαφικά δείγματα συλλέχθηκαν από τα πρώτα 20 εκατοστά. Η εκτίμηση της δομής της μικροβιακής κοινότητας (Gram+ και Gram- βακτήρια, ακτινομύκητες, μύκητες, συνολική βακτηριακή και μικροβιακή βιομάζα) έγινε με τη μέθοδο των φωσφολιπιδίων (Phospholipid Fatty Acid Analysis) ενώ για τους νηματώδεις έγινε καταμέτρηση και ταξινόμηση σε γένη.
description: In the present study, the short-term effect of three pesticides was tested: the insecticide karate Zeon with the active substance l-cyhalothrin, and the fungicides Score and Ortiva with the active substances difenoconazole and azoxystrobin, respectively. Their effect, both individually and in combination, on the structure of the soil microbial and nematode community was studied. For this study, 20 experimental plots of 5 X 5 = 25m2 each were installed. A total of 4 different treatments were applied with 5 replicates for each: no intervention (Control), leaf spray with insecticide, leaf spray with the 2 fungicides and spraying with a combination of fungicides and insecticide. The first sampling was carried out before the application of the treatments (June 2021), then followed by the sprays applied in triplicate with an interval of 15 days, and the second sampling was carried out three months after the last application. The assessment of the microbial community structure (Gram+ and Gram- bacteria, actinomycetes, fungi, total bacterial and microbial biomass) was performed by the Phospholipid Fatty Acid Analysis method, while the nematodes were counted and classified into genera.

Overview

 

El aliento de los dioses oWarbreaker, segunda novela de Brandon Sanderson, es unarara avis en la fantasía épica: una narración completa en un único volumen, con toda la imaginación, la aventura, la magia y los entrañables personajes a los que este autor, destinado a heredar el trono de todo un género, nos tiene acostumbrados. Hace años, el monarca de Idris firmó un tratado con el reino de Hallandren según el cual el rey Dedelin enviaría a su hija mayor, Vivenna, para casarse con Susebron, el rey-dios de Hallabdren. Vivenna ha sido adiestrada durante toda su vida para ser una novia adecuada para Susebron y así cumplir con su deber y ayudar a forjar una paz estable entre los dos reinos. Ese era el plan, pero el monarca de Idris envía a su hija Siri, desobediente e independiente, en lugar de Vivenna. Mientras intenta encontrar su lugar en la corte de Susebron, Siri descubre la verdad oculta sobre el rey-dios. En Idris, Vivenna se siente intranquila y teme que su hermana no esté preparada para esa nueva vida, por lo que decide viajar a Hallandren. Allí se reúne con la gente de Idris que trabaja en la capital, Telir, y comienza una nueva vida de espionaje y sabotaje.El plan de Vivenna es rescatar a Siri, aunque tal vez esta ni necesite ni desee ser salvada.Res...

description: Purpose: The class of models that can be represented by STL files is larger than the class of models that can be printed using additive manufacturing technologies. Stated differently, there exist well-formed STL files that cannot be printed. In this paper such a gap is formalized and a fully automatic procedure is described to turn any such file into a printable model. Approach: Based on well-established concepts from combinatorial topology, we provide an unambiguous description of all the mathematical entities involved in the modeling-printing pipeline. Specifically, we formally define the conditions that an STL file must satisfy to be printable and, based on these, we design an as-exact-as-possible repairing algorithm. Findings: We have found that, in order to cope with all the possible triangle configurations, the algorithm must distinguish between triangles that bound solid parts and triangles that constitute zero-thickness sheets. Only the former set can be fixed without distortion. Originality: Previous methods that are guaranteed to fix all the possible configurations provide only approximate solutions with an unnecessary distortion. Conversely, our procedure is as exact as possible, meaning that no visible distortion is introduced unless it is strictly imposed by limitations of the printing device. Thanks to such an unprecedented flexibility and accuracy, this algorithm is expected to significantly simplify the modeling-printing process, in particular within the continuously emerging non-professional "maker" communities.
