description: We present revised near-infrared albedo fits of 2835 Main Belt asteroids observed by WISE/NEOWISE over the course of its fully cryogenic survey in 2010. These fits are derived from reflected-light near-infrared images taken simultaneously with thermal emission measurements, allowing for more accurate measurements of the near-infrared albedos than is possible for visible albedo measurements. As our sample requires reflected light measurements, it undersamples small, low albedo asteroids, as well as those with blue spectral slopes across the wavelengths investigated. We find that the Main Belt separates into three distinct groups of 6%, 16%, and 40% reflectance at 3.4 um. Conversely, the 4.6 um albedo distribution spans the full range of possible values with no clear grouping. Asteroid families show a narrow distribution of 3.4 um albedos within each family that map to one of the three observed groupings, with the (221) Eos family being the sole family associated with the 16% reflectance 3.4 um albedo group. We show that near-infrared albedos derived from simultaneous thermal emission and reflected light measurements are an important indicator of asteroid taxonomy and can identify interesting targets for spectroscopic followup.

description: We study the relations between a contract automata and an interaction model. In the former model, distributed services are abstracted away as automata - oblivious of their partners - that coordinate with each other through an orchestrator. The interaction model relies on channel-based asynchronous communication and choreography to coordinate distributed services. We define a notion of strong agreement on the contract model, exhibit a natural mapping from the contract model to the interaction model, and give conditions to ensure that strong agreement corresponds to well-formed choreography.

description: A series of 27 B-cell lymphomas (designated the CH series), induced in B10.H-2aH-4b p/Wts mice by intense adoptive immunization with sheep erythrocytes, was found to represent a subset of the total B-cell repertoire. This subset was characterized by expression of a limited number of Ig heavy chain variable regions, as evidenced by the presence of cross-reactive idiotypes and common antigen binding specificities. Twenty-one of the 27 CH lymphomas studied were classified into five groups, defined by a particular cross-reactive idiotype; four of these groups were linked in a single network. Seven of 16 idiotypes defined by absorption analysis were present on lymphomas bearing either kappa or lambda light chains and so were localized to the heavy chain variable region. The surface Ig on 14 CH lymphomas was found to be specific for epitopes on certain erythrocytes (bromelain-treated autologous erythrocytes, sheep, and chicken erythrocytes) or E. coli. We propose that the CH lymphomas represent the malignant counterparts of a subset of idiotypically related, normal B cells in B10.H-2aH-4b p/Wts mice. Perturbation of this idiotype network, by hyperimmunization with an antigen for which some of the members are specific (sheep erythrocytes), increases the risk for neoplasia. Possible mechanisms for this are discussed.

description: A heat-labile Epstein-Barr virus-specific DNA polymerase stimulatory protein having a molecular mass of 45 kDa was purified from phorbol 12-myristate 13-acetate-treated P3HR-1 cells by column chromatography. The virus DNA polymerase stimulatory protein was precipitated by sera from patients with nasopharyngeal carcinoma but not by sera from healthy donors. The interaction of the stimulatory protein with DNA polymerase was stoichiometric. Furthermore, this protein stimulated Epstein-Barr virus DNA polymerase but not herpes simplex virus type 1 or type 2 or human DNA polymerase alpha. The stimulatory protein did not alter the Km value of dTTP or DNA but did increase the Vmax of DNA polymerase. Salt concentrations between 100 mM and 150 mM KCl were optimal for this protein-induced stimulation of Epstein-Barr virus DNA polymerase activity. The presence of the stimulatory protein in the reaction mixture enhanced the sensitivity of virus DNA polymerase to phosphonoformate.

description: Accretion of fields by black holes is a subject of great interest in physics. It is known that accretion plays a fundamental role in active galactic nuclei and in the evolution of black holes. Accretion of fundamental fields is often related to the study of absorption cross section. Basically all black holes for which absorption of fields has been studied so far present singularities. However, even within general relativity, it is possible to construct regular black holes: objects with event horizons but without singularities. Many physically motivated regular black hole solutions have been proposed in the past years, demanding the understanding of their absorption properties. We study the absorption of planar massless scalar waves by Bardeen regular black holes. We compare the absorption cross section of Bardeen and Reissner--Nordström black holes, showing that the former always have a bigger absorption cross section for fixed values of the field frequency and of the normalized black hole charge. We also show that it is possible for a Bardeen black hole to have the same high-frequency absorption cross section of a Reissner--Nordström black hole. Our results suggest that, in mid-to-high-frequency regimes, regular black holes can have compatible properties with black holes with singularities, as far as absorption is concerned.

description: We introduce a new statistic, 'spectral goodness of fit' (SGOF) to measure how well a network model explains the structure of an observed network. SGOF provides an absolute measure of fit, analogous to the standard R-squared in linear regression. Additionally, as it takes advantage of the properties of the spectrum of the graph Laplacian, it is suitable for comparing network models of diverse functional forms, including both fitted statistical models and algorithmic generative models of networks. After introducing, defining, and providing guidance for interpreting SGOF, we illustrate the properties of the statistic with a number of examples and comparisons to existing techniques. We show that such a spectral approach to assessing model fit fills gaps left by earlier methods and can be widely applied.

description: Experiences of virtual reality (VR) can easily break if the method of evaluating subjective user states is intrusive. Behavioral measures are increasingly used to avoid this problem. One such measure is eye tracking, which recently became more standard in VR and is often used for content-dependent analyses. This research is an endeavor to utilize content-independent eye metrics, such as pupil size and blinks, for identifying mental load in VR users. We generated mental load independently from visuals through auditory stimuli. We also defined and measured a new eye metric, focus offset, which seeks to measure the phenomenon of “staring into the distance” without focusing on a specific surface. In the experiment, VR-experienced participants listened to two native and two foreign language stimuli inside a virtual phone booth. The results show that with increasing mental load, relative pupil size on average increased 0.512 SDs (0.118 mm), with 57% reduced variance. To a lesser extent, mental load led to fewer fixations, less voluntary gazing at distracting content, and a larger focus offset as if looking through surfaces (about 0.343 SDs, 5.10 cm). These results are in agreement with previous studies. Overall, we encourage further research on content-independent eye metrics, and we hope that hardware and algorithms will be developed in the future to further increase tracking stability.

description: The windshield is one of a car's most important safety features because it protects the driver from the weather and keeps debris from getting into the car. But when a windshield is replaced, the Advanced Driver Assistance System (ADAS) must be reset. With correct calibration of the ADAS, the car's safety and the driver's ability to control it can be protected. This article will talk about how important it is to recalibrate ADAS after getting a new windshield and what could happen if you don't.

description: This paper describes an approach to estimate the photosynthetic capacity and derive the optimum fruit number for each individual tree, in order to achieve a defined fruit size, which is named as the fruit bearing capacity of the tree. The estimation of fruit bearing capacity was carried out considering the total leaf area per tree as measured with a 2-D LiDAR laser scanner, LALiDAR, and key carbon-related variables of the trees including leaf gas exchange, fruit growth and respiration, in two commercial apple orchards. The range between minLALiDAR and maxLALiDAR was found to be 2.4 m on Pinova and 4.3 m on RoHo 3615 at fully developed canopy. The daily C requirement of the growing fruit and the associated leaf area demand, necessary to meet the average daily fruit C requirements showed seasonal variation, with maximum values in the middle of the growing period. The estimated fruit bearing capacity ranged from 33-95 fruit tree-1 and 45-121 fruit tree-1 on the trees of Pinova and RoHo 3615, respectively. This finding demonstrates sub-optimal crop load at harvest time in both orchards, above or below the fruit bearing capacity for individual trees. In conclusion, the LiDAR measurements of the leaf area combined with a carbon balance model allows for the estimation of fruit bearing capacity for individual trees for precise crop load management. © 2020 Polish Academy of Sciences.

Some of the barriers influencing the enhancement of the quality of graphic design education in Jordanian universities from the perspectives of lecturers, students, and industry practitioners

description: The finding that Graphic Design education in Jordan is in far from ideal conditions is robustly evidenced, despite multiple interventions to improve the quality of teaching and learning. This study sought to identify and critically evaluate some of the barriers affecting the enhancement of the quality of Graphic Design education in Jordanian universities from the perspectives of lecturers, students, and industry practitioners. Thus, three related sub-studies were undertaken. Study I is a comparative case study of learning outcomes in relevant programmes in Cardiff Metropolitan University, UK, and Philadelphia University, Jordan. Data was gathered by archival research. Study II formed a Graphic Design focussed survey in Jordan that sampled 220 Year 1/ Year 4 students, 270 practitioners, and 26 lecturers, to ascertain the state of Graphic Design education in Jordan. The main Study, III, sought to ascertain the states of: implementation of the fieldwork module; theoretical and practical modules; quality assurance; Wasta; and creative problem-solving. It employed a multiple case study strategy and a sample of 12 purposefully selected specialist lecturers in Graphic Design in Jordanian universities. This study argues that such specialist Graphic Design lecturers individually hold the most promising prospects for change in the short-term, despite the inertia occasioned by the capacity-handicapped Ministry of Higher Education and Scientific Research, and the much greater numbers of generalist lecturers who remain unspecialised, and unmotivated. Such short-term change could be reached through: increased awareness/focus on creative problem-solving; wresting control over Graphic Design modules from disinterested Schools; and adoption of constructive alignment and blended learning among others. Without a systemic approach to the problems facing Graphic Design education in Jordan, a lasting solution is unlikely. This study reappraises the problems and past interventions for suitability, implementation, and effectiveness, and proposes other interventions, with emphasis on how to get more within the current capacity.

description: We apply boundary integral equations for the first time to the two-dimensional scattering of time-harmonic waves from a smooth obstacle embedded in a continuously-graded unbounded medium. In the case we solve the square of the wavenumber (refractive index) varies linearly in one coordinate, i.e. $(Δ+ E + x_2)u(x_1,x_2) = 0$ where $E$ is a constant; this models quantum particles of fixed energy in a uniform gravitational field, and has broader applications to stratified media in acoustics, optics and seismology. We evaluate the fundamental solution efficiently with exponential accuracy via numerical saddle-point integration, using the truncated trapezoid rule with typically 100 nodes, with an effort that is independent of the frequency parameter $E$. By combining with high-order Nystrom quadrature, we are able to solve the scattering from obstacles 50 wavelengths across to 11 digits of accuracy in under a minute on a desktop or laptop.

description: Spatially resolving light detectors allow, with proper calibration, quantitative analysis of the variations in two-dimensional intensity distributions over time. An ultrasensitive microfluorometer was assembled by using as a detector a microchannel plate-intensified video camera. The camera was interfaced with a software-based digital video analysis system to digitize, average, and process images and to directly control the timing of the experiments to minimize exposure of the specimen to light. The detector system has been characterized to allow its use as a photometer. A major application has been to perform fluorescence recovery after photobleaching measurements by using the camera in place of a photomultiplier tube (video-FRAP) with the goal of detecting possible anisotropic diffusion or convective flow. Analysis of the data on macromolecular diffusion in homogenous aqueous glycol solutions yielded diffusion constants in agreement with previous measurements. Results on lipid probe diffusion in dimyristoylphosphatidylcholine multibilayers indicated that at temperatures above the gel-to-liquid crystalline phase transition diffusion is isotropic, and analysis of video-FRAP data yielded diffusion coefficients consistent with those measured previously by using spot photobleaching. However, lipid probes in these multibilayers held just below the main phase transition temperature exhibited markedly anisotropic diffusive fluxes when the bleaching beam was positioned proximate to domain boundaries in the P beta' phase. Lipid probes and lectin receptor complexes diffused isotropically in fibroblast surface membranes with little evidence for diffusion channeled parallel to stress fibers. A second application was to trace the time evolution of cell surface reactions such as patching. The feasibility of following, on the optical scale, the growth of individual receptor clusters induced by the ligand wheat germ agglutinin was demonstrated.

description: Transmembrane electrical activity in pituitary tumor cells can be altered by substances that either stimulate or inhibit their secretory activity. Using patch recording techniques, we have measured the resting membrane potentials, action potentials, transmembrane macroscopic ionic currents, and single Ca2+-activated K channel currents of GH3 and GH4/C1 rat pituitary tumor cells in response to thyrotropin-releasing hormone (TRH). TRH, which stimulates prolactin secretion, causes a transient hyperpolarization of the membrane potential followed by a period of elevated action potential frequency. In single cells voltage clamped and internally dialyzed with solutions containing K+, TRH application results in a transient increase in Ca2+-activated K currents and a more protracted decrease in voltage-dependent K currents. However, in cells internally dialyzed with K+-free solutions, TRH produces no changes in inward Ca2+ or Ba2+ currents through voltage-dependent Ca channels. The time courses of the effects on Ca2+-activated and voltage-dependent K currents correlate with the phases of hyperpolarization and hyperexcitability, respectively. During application of TRH to whole cells, single Ca2+-activated K channel activity increases in cell-attached patches not directly exposed to TRH. In contrast, TRH applied directly to excised membrane patches produces no change in single Ca2+-activated K channel behavior. We conclude that TRH (i) triggers intracellular Ca2+ release, which opens Ca2+-activated K channels, (ii) depresses voltage-dependent K channels during the hyperexcitable phase, which further elevated intracellular Ca2+, and (iii) does not directly modulate Ca channel activity.

description: With electronegativity and hardness of an atom defined as 1/2(I + A) and 1/2(I - A), respectively, where I and A are the ionization potential and electron affinity, electronegativity difference and hardness sum are proposed as coordinates in structure stability diagrams. With these coordinates a successful topological classification of the crystal structures of octet and suboctet binary compounds is obtained, and a clear delineation of the structural classes portraying chemical periodicity is found.

description: Stellar variability in the near-infrared (NIR) remains largely unexplored. The exploitation of public science archives with data-mining methods offers a perspective for the time-domain exploration of the NIR sky. We perform a comprehensive search for stellar variability using the optical-NIR multi-band photometric data in the public Calibration Database of the WFCAM Science Archive (WSA), with the aim of contributing to the general census of variable stars, and to extend the current scarce inventory of accurate NIR light curves for a number of variable star classes. We introduce new variability indices designed for multi-band data with correlated sampling, and apply them for pre-selecting variable star candidates, i.e., light curves that are dominated by correlated variations, from noise-dominated ones. Pre-selection criteria are established by robust numerical tests for evaluating the response of variability indices to colored noise characteristic to the data. We find 275 periodic variable stars and an additional 44 objects with suspected variability with uncertain periods or apparently aperiodic variation. Only 44 of these objects had been previously known, including 11 RR~Lyrae stars in the outskirts of the globular cluster M3 (NGC~5272). We provide a preliminary classification of the new variable stars that have well-measured light curves, but the variability types of a large number of objects remain ambiguous. We classify most of the new variables as contact binary stars, but we also find several pulsating stars, among which 34 are probably new field RR~Lyrae and 3 are likely Cepheids. We also identify 32 highly reddened variable objects close to previously known dark nebulae, suggesting that these are embedded young stellar objects. We publish our results and all light-curve data as the WFCAM Variable Star Catalog.

description: We have independently isolated and characterized cDNA and genomic clones for the human coagulation factor IX. Sequence analysis in both cases indicates that threonine is encoded by the triplet ACT as the third residue of the activation peptide. This is in agreement with some earlier reports but in disagreement with others that show the alanine triplet GCT at this position. The discrepancy can thus be accounted for by natural variation of a single nucleotide in the normal population. Amino acid sequence analyses of activated factor IX from plasma samples of four individuals yielded two cases of alanine and two cases of threonine at the third position of the activation peptide. In factor IX from pooled plasma and in factor IX from a heterozygous individual, however, both alanine and threonine were found. Taken together, the findings show that a prevalent nondeleterious dimorphism exists in the activation peptide of human coagulation factor IX.

description: One of the major surprises of the molecular analysis of major histocompatibility complex (MHC) genes is the large number of class I (K/D)-related sequences in the genome. Both restriction fragment length polymorphisms and cosmid cloning experiments showed them all to be closely linked to the MHC. Until now little information was available concerning either their expression or recognition by the immune system. Here we report that these non-K/D genes can provoke antibody responses and be recognized by cytolytic T cells. Immunization of C3H mice with L cells transfected with class I genomic clones resulted in antisera that reacted preferentially with cells from strain B10.P (the gene donor). Thus, these genes can be expressed by L cells. These products were recognized by cytolytic T cells produced by mixed lymphocyte culture with B10.P stimulators. One gene, represented in clone lambda 3a, was chosen for further analysis. A restriction fragment length polymorphism, detected between B10.P (KpDp) and B10.F(14R) (KbDp) and between B10 (KbDb) and B10.F(13R) (KpDb), has enabled us to map the lambda 3a sequence to the D or Tla region. Restriction endonuclease mapping of the lambda 3a clone shows that the gene is intact and that, although many restriction sites are conserved, the gene in lambda 3a differs from other class I genes. When the lambda 3a clone was transfected into mouse L cells, a new product was expressed. Cells expressing this product (designated L3a cells) were killed by primary D-end-reactive, allospecific cytolytic T lymphocytes. The L3a cells were unreactive with monoclonal antibodies specific for the Kp,Dp,Qa-2, Tla.3, and Tla.5 molecules.
YANG-MILLS THEORY WITH A SCALAR FIELD: A UNIFIED MODEL FOR CONFINEMENT AND MASS GAP

description: We propose a new model for the mass gap problem in Yang-Mills theory, based on the introduction of a confinement particle that mediates the confinement force binding quarks together into color-singlet states. Our proposed Lagrangian density describes the confinement particle's behavior and interactions with quarks. We show that the confinement particle naturally explains the mass gap problem, and discuss its implications for nonperturbative phenomena and the renormalization of the theory. Our model provides a new mechanism for understanding the fundamental interactions of quarks and gluons, with potential implications for a range of areas in theoretical physics

description: The three-dimensional purely plaquette gonihedric Ising model and its dual are investigated to resolve inconsistencies in the literature for the values of the inverse transition temperature of the very strong temperature-driven first-order phase transition that is apparent in the system. Multicanonical simulations of this model allow us to measure system configurations that are suppressed by more than 60 orders of magnitude compared to probable states. With the resulting high-precision data, we find excellent agreement with our recently proposed nonstandard finite-size scaling laws for models with a macroscopic degeneracy of the low-temperature phase by challenging the prefactors numerically. We find an overall consistent inverse transition temperature of 0.551334(8) from the simulations of the original model both with periodic and fixed boundary conditions, and the dual model with periodic boundary conditions. For the original model with periodic boundary conditions, we obtain the first reliable estimate of the interface tension, 0.12037(18), using the statistics of suppressed configurations.

description: Circadian rhythms are biological rhythms with a period close to 24 h. They become entrained to the Earth’s solar day via different periodic cues, so-called zeitgebers. The entrainment of circadian rhythms to a single zeitgeber was investigated in many mathematical clock models of different levels of complexity, ranging from the Poincaré oscillator and the Goodwin model to biologically more detailed models of multiple transcriptional translational feedback loops. However, circadian rhythms are exposed to multiple coexisting zeitgebers in nature. Therefore, we study synergistic effects of two coexisting zeitgebers on different components of the circadian clock. We investigate the induction of period genes by light together with modulations of nuclear receptor activities by drugs and metabolism. Our results show that the entrainment of a circadian rhythm to two coexisting zeitgebers depends strongly on the phase difference between the two zeitgebers. Synergistic interactions of zeitgebers can strengthen diurnal rhythms to reduce detrimental effects of shift-work and jet lag. Medical treatment strategies which aim for stable circadian rhythms should consider interactions of multiple zeitgebers.

description: We explore the surprisingly rich energy landscape of origami-like folding planar structures. We show that the configuration space of rigid-paneled degree-4 vertices, the simplest building blocks of such systems, consists of at least two distinct branches meeting at the flat state. This suggests that generic vertices are at least bistable, but we find that the nonlinear nature of these branches allows for vertices with as many as five distinct stable states. In vertices with collinear folds and/or symmetry, more branches emerge leading to up to six stable states. Finally, we introduce a procedure to tile arbitrary 4-vertices while preserving their stable states, thus allowing the design and creation of multistable origami metasheets.

description: Στο σύγχρονο περιβάλλον ασφαλείας οι υβριδικές απειλές αποτελούν ένα πολυδιάστατο εργαλείο για τους επιτιθέμενους δρώντες. Ταυτόχρονα, σε ένα περιβάλλον παρατεταμένης κρίσης και ενός μεταβαλλόμενου παγκόσμιου συστήματος ισορροπίας ισχύος (status quo), η μετανάστευση ως ένα διαχρονικό φαινόμενο, δύναται να εργαλειοποιηθεί και να αποτελέσει ένα μέσο εξαναγκασμού. Σε αυτό το πλαίσιο, η ΕΕ καλείται να διαχειριστεί τα εξωτερικά της σύνορα, προασπίζοντας την εσωτερική της ασφάλεια και αντιμετωπίζοντας τις υβριδικές επιθέσεις με τη μορφή της στρατηγικά κατευθυνόμενης ή στρατηγικά σχεδιασμένης μετανάστευσης. Στην παρούσα εργασία, η ανάλυση πραγματοποιείται μέσω της ποιοτικής και περιγραφικής ανάλυσης, της μελέτης περίπτωσης και της βιβλιογραφικής ανασκόπησης. Επιπλέον, προτείνεται ως πληρέστερος περιγραφικά όρος η στρατηγικά κατευθυνόμενη μετανάστευση. Ακόμη, επιχειρείται η σε βάθος προσέγγιση των υβριδικών απειλών, η μελέτη των ευρωπαϊκών πολιτικών και η ανάλυση της στρατηγικά κατευθυνόμενης μετανάστευσης στο ευρωπαϊκό πλαίσιο ασφάλειας και διαχείρισης των εξωτερικών συνόρων. Μέσω της έρευνας, εντοπίζεται η επιρροή των υβριδικών απειλών στο στρατηγικό, επιχειρησιακό και τακτικό επίπεδο και υπογραμμίζεται η σημασία της προπαγάνδας και του βοηθητικού βραχίονα, στη δράση του συμπλέγματος «οργανωμένο έγκλημα-μετανάστευση-επιτιθέμενοι δρώντες». Τέλος, ως κύριες ευπάθειες του συστήματος διαχείρισης των εξωτερικών συνόρων εντοπίζονται στο πολιτικό και επιχειρησιακό επίπεδο, ενώ η αποτελεσματικότητα της στρατηγικής διαχείρισης εδράζεται στην ολιστική αντίληψη των απειλών, τη θεσμική ανθεκτικότητα και την επιχειρησιακή ετοιμότητα του αμυνόμενου δρώντα.

description: To identify a signal involved in transporting a ribosomal protein to the nucleus, we constructed hybrid genes encoding amino-terminal segments of yeast ribosomal protein L3 joined to the amino-terminal end of the entire Escherichia coli beta-galactosidase molecule. The subcellular locations of the corresponding hybrid proteins in yeast were determined by in situ immunofluorescence. The first 21 amino acids of L3 were sufficient to localize beta-galactosidase to the nucleus. This region shows limited homology to portions of other nuclear proteins identified as essential for their transport. Larger fusion proteins were also localized to the nucleus. However, a hybrid protein containing all but the 14 carboxyl-terminal amino acids from L3 initially failed to localize; this defect was corrected by inserting a glycine- and proline-containing bridge between the L3 and beta-galactosidase moieties. The renovated protein was able to associate with ribosomes, suggesting that, in addition to entering the nucleus, this hybrid polypeptide was assembled into 60S ribosomal subunits that were subsequently exported to the cytoplasm.

description: Controlling and reversing the effects of loss are major challenges in optical systems. For lasers losses need to be overcome by a sufficient amount of gain to reach the lasing threshold. We show how to turn losses into gain by steering the parameters of a system to the vicinity of an exceptional point (EP), which occurs when the eigenvalues and the corresponding eigenstates of a system coalesce. In our system of coupled microresonators, EPs are manifested as the loss-induced suppression and revival of lasing. Below a critical value, adding loss annihilates an existing Raman laser. Beyond this critical threshold, lasing recovers despite the increasing loss, in stark contrast to what would be expected from conventional laser theory. Our results exemplify the counterintuitive features of EPs and present an innovative method for reversing the effect of loss.

description: Agri-food has become an economic sector under increasing pressure in order to support food demand and decrease environmental impacts. One valuable methodology to evaluate environmental impacts is life cycle assessment (LCA), which has been employed in different economic sectors, however, beekeeping has been scarcely explored. In this context, this article investigates the environmental profile of 31 Chilean beekeeping systems reporting 15 environmental impact categories with a cradle to gate approach. In this way, this study identifies key contributing activities, variability in the environmental impacts, differences among operation scales, and provided efficient management practices for policy-makers. To the best of our knowledge, this is the first study that conducts a wide environmental analysis of beekeeping systems through LCA. The results show that feeding is the most impacting activity in all categories, followed by hives transport. Otherwise, medication, consumption of disposable inputs and honey extraction contribute less than 5% in average across all categories. Regarding the operation scale, the results suggest that small-scale beekeepers have the lowest environmental performance. Otherwise, medium-scale beekeepers have better environmental performance than the large-scale ones, depending on the environmental impact category evaluated. Finally, managerial practices in order to achieve sustainable honey production are provided.

description: The Deliverable 6.1 of the MobiSpaces project “Use Cases Co-Creation & Design Activities v1” aims to deliver the co-creation activities and design for the different Use Case (UC) scenarios. This deliverable aims to provide an overview of co-creation and design activities for different UC scenarios and to analyse the requirements of the UCs involved to define the necessary implementation actions. The first part of the document describes the theoretical approach of co-creation and the role of User Interface (UI)/User Experience (UX) design, suggesting both the methodology and related guidelines to be applied according to the context, i.e., that of co-design, and associated tools, i.e., sketches, wireframes, and mock-ups. The document then proceeds to illustrate a description of each of the five UCs: from the goals and objectives and the relative scenarios to the dataset description, including the information concerning the current infrastructure. Furthermore, a timeline for the co-creation processes is given. Overall, this deliverable highlights the key points of the guidelines to make the application of the co-creation process constructive to the project UCs and related scenarios to maximise cooperation and smooth integration between the partners.

description: Due to their ultra-short duration and peak currents in the kA range, laser-wakefield accelerated electron bunches are promising drivers for ultrafast X-ray generation in compact free-electron-lasers (FELs), Thomson-scattering or betatron sources. Here we present the first single-shot, high-resolution measurements of the longitudinal bunch profile obtained without prior assumptions about the bunch shape. Our method allows complex features, such as multi-bunch structures, to be detected. Varying the length of the gas target, and thus the acceleration length, enables an assessment of the bunch profile evolution during the acceleration process. We find a minimum bunch duration of 4.2 fs (full width at half maximum) with shot-to-shot fluctuation of 11% rms. Our results suggest that after depletion of the laser energy, a transition from a laser-driven to a particle-driven wakefield occurs, associated with the injection of a secondary bunch. The resulting double-bunch structure might act as an elegant approach for driver-witness type experiments, i.e. allowing a non-dephasing-limited acceleration of the secondary bunch in a plasma-afterburner stage.

description: Human heparin cofactor II is a plasma protein that is known to inhibit thrombin. The rate of thrombin inhibition by heparin cofactor II is accelerated (greater than or equal to 1000-fold) in the presence of the glycosaminoglycans, heparin and dermatan sulfate. We have found that chymotrypsin A alpha is also inhibited by heparin cofactor II with a second-order rate constant value of 1.8 X 10(6) M-1 X min-1 at pH 8.0 and 25 degrees C. However, there was no measurable effect of heparin or dermatan sulfate on the rate of chymotrypsin inhibition. Arginine-modified heparin cofactor II showed a comparable percentage loss of both antichymotrypsin and antithrombin activities. Heparin cofactor II and chymotrypsin formed a stable complex with a Mr value near 90,000 when analyzed by NaDodSO4/polyacrylamide gel electrophoresis; this suggests a 1:1 reaction stoichiometry. The chymotrypsin cleavage site in heparin cofactor II was the same as that for thrombin, and primary structure analysis of the inhibitor showed a P'1-P'8 sequence of Ser-Thr-Gln-Val-Arg-Phe-Thr-Val ... . The results indicate that, in contrast to alpha 1-antichymotrypsin, which does not inhibit trypsin-like enzymes, including thrombin, heparin cofactor II can effectively inhibit both thrombin and chymotrypsin.
