description: Rice–wheat (RW) cropping system in India is a major source of N2O emissions. In such system, defining N rates that deliver minimal N2O emissions and economically optimum yield would benefit both food production and the environment. We measured yield and N2O fluxes from RW systems in Northwest IGP under two tillage systems and five N rates (0, 75, 150, 225 and 300 kg N ha−1) for both rice and wheat using static chamber method. Seasonal pattern of N2O emission was mainly influenced by fertilizer and water application events with no significant effect of tillage systems. Mean annual N2O emission from RW system was 1.49 kg N ha−1 in N75 plot and 2.97–3.04 in the plots receiving ≥150 kg N ha−1. On average, the yield-scaled N2O emissions of rice and wheat were 0.25 and 0.52 kg N2O–N mg−1, respectively. Our finding suggests that N rates between 120–200 kg N ha−1 in rice and 50–185 kg ha−1 in wheat provide the most economical returns and application rates beyond these ranges would be both economically and environmentally unsustainable. Within the range of N rate studied, fertilizer-induced N2O-EF for rice and wheat were 0.41% and 0.79%, respectively.

description: NH4+ nutrition has emerged as an effective approach to generate salt tolerance in sorghum plants. Our hypothesis was that salt-tolerance mechanisms in NH4+-grown sorghum are related to rapid absorption and assimilation of NH4+ as well as favorable K+ uptake. Sorghum plants were grown in nutrient solutions containing NO3− or NH4+ and subjected to NaCl at 75 mM. Under control conditions, K+ uptake was more pronounced in NO3− than that of NH4+-fed plants. Under salinity, NH4+-grown plants showed lower Na+ and higher K+ contents than NO3–grown plants at 1 and 10 days after salt exposure, and thereby increased K+/Na+ ratio. The data indicate that NH4+ does not increase K+ uptake under salt stress conditions, but decrease the K+ efflux and maintain an elevated K+/Na+ ratio in tissues. In parallel, sorghum plants displayed elevated NH4+ uptake, evidenced by higher Vmax for NH4+, assimilating a higher amount of NH4+ into amino acids in roots; whereas NO3−-fed plants accumulated NH4+ in the shoot. In conclusion, NH4+-fed salt-stressed sorghum plants maintain favorable K+/Na+ homeostasis due to greater retention of K+ in tissues together with restricting control of Na+ accumulation and transport. S. bicolor face to NH4+ toxicity by activating mechanisms for rapid inorganic N-assimilation.

description: Symbolic controller synthesis is a fully-automated and correct-by-design synthesis scheme whose limitations are its immense memory and runtime requirements. A current trend to compensate for this downside is to develop techniques for parallel execution of the scheme both in mathematical foundation and in software implementation. In this paper we present a generalized Bellman-Ford algorithm to be used in the so-called symbolic optimal control, which is an extension of the aforementioned synthesis scheme. Compared to the widely used Dijkstra algorithm our algorithm has two advantages. It allows for cost functions taking arbitrary (e.g. negative) values and for parallel execution with the ability for trading processing speed for memory consumption. We motivate the usefulness of negative cost values on a scenario of aerial firefighting with unmanned aerial vehicles. In addition, this four-dimensional numerical example, which is rich in detail, demonstrates the great performance of our algorithm.

The resulting oscillation frequencies of the core radius reproduce the trends seen in recent experiments [Engels et al., Phys. Rev.

description: We present the long term X-ray light curves, detailed spectral and timing analyses of XTE J1908+094 using the Rossi X-ray Timing Explorer Proportional Counter Array observations covering two outbursts in 2002 and early 2003. At the onset of the first outburst, the source was found in a spectrally low/hard state lasting for ~40 days, followed by a three day long transition to the high/soft state. The source flux (in 2$-$10 keV) reached $\sim$100 mCrab on 2002 April 6, then decayed rapidly. In power spectra, we detect strong band-limited noise and varying low-frequency quasi periodic oscillations that evolved from ~0.5 Hz to ~5 Hz during the initial low/hard state of the source. We find that the second outburst closely resembled the spectral evolution of the first. The X-ray transient's overall outburst characteristics lead us to classify XTE J1908+094 as a black-hole candidate. Here we also derive precise X-ray position of the source using Chandra observations which were performed during the decay phase of the first outburst and following the second outburst.

description: In ground based astronomical observations, atmospheric dispersion shifts the image of the object at different wavelengths due to the wavelength-dependent index of refraction of the atmosphere. Thus, using an Atmospheric Dispersion Corrector (ADC) is mandatory in order to avoid any wavelength dependent losses. Typical ADC configurations, for high resolution astronomical instruments, are two counter-rotating prisms, a set of, at least, four prisms paired together. With the arrival of large telescopes with higher angular magnification, and spectrographs with higher resolution, the requirements on the dispersion correction are becoming more critical due to the impact on the produced science (e.g. radial velocity precision). We developed an ADC optical design tool in order to select the best set of glasses in terms of residuals, transmission, resulting image quality, Fresnel losses, taking into account the required spectral range and typical atmospheric conditions where the ADC will be working. A demonstration of the capabilities of the tool is presented with the analysis of the impact of different melt data, the effect of different glass Sellmeier coefficients between catalog and measured ones, that can create a difference in the residuals above few tens of milli-arcseconds (mas). The tool allows the investigation of critical steps on the ADC design phase and speeds up the glass selection process critical for the harder requirements of the future instruments/telescopes.

description: We investigate dimension five Lorentz-violating nonminimal interactions in the electroweak sector, in connection with the possible generation of electric dipole moment (EDM), weak electric dipole moment (WEDM), magnetic dipole moment (MDM) and weak magnetic dipole moment (WMDM) for leptons. These couplings are composed of the physical fields and LV tensors of ranks ranging from 1 to 4. The CPT-odd couplings do no generate EDM\ behavior and do not provide the correct MDM\ signature, while the CPT-even ones yield EDM and MDM\ behavior, being subject to improved constraining. Tau lepton experimental data is used to constrain the WEDM\ and WMDM couplings to the level of $10^{-4}\left( \text{GeV}\right) ^{-1},$ whereas electron MDM and EDM data is employed to improve constraints to the level of $10^{-17}\left( \text{GeV}\right) ^{-1}$ and $10^{-11}\left( \text{GeV}\right) ^{-1},$ respectively.

description: Recently the ferroelectric anomaly (Nad, Monceau, et al) followed by the charge disproportionation (Brown, et al) have been discovered in (TMTTF)2X compounds. The corresponding theory of the combined Mott-Hubbard state describes both effects by interference of the build-in nonequivalence of bonds and the spontaneous one of sites. The state gives rise to three types of solitons: πsolitons (holons) are observed via the activation energy Δin the conductivity $G$; noninteger αsolitons (the FE domain walls) provide the frequency dispersion of the ferroelectric response; combined spin-charge solitons determine G(T) below subsequent structural transitions of the tetramerisation. The photoconductivity gap 2Δis determined by creations of soliton - antisoliton pairs. The optical edge lies well below, given by the collective ferroelectric mode which coexists with the combined electron-phonon resonance and the phonon antiresonance. The charge disproportionation and the ferroelectricity can exist hiddenly even in the Se subfamily giving rise to the unexplained yet low frequency optical peak, the enhanced pseudogap and traces of phonons activation.

Here we report a new dilignan, archidendronin A (1), along with one known sesquilignan (2). Their structures were determined by extensive spectroscopic methods, including UV, HRESIMS, 1 D and 2 D NMR data. The inhibitory activity on Aβ1-42 aggregation was screened by ThT assay with curcumin as the positive control, and compounds 1 and 2 showed inhibition rate of 60.0% and 64.4% at 20 μM, respectively.
Role of the Surface Energy in Heavy-Ion Collisions

description: The surface energy is one of the fundamental properties nuclei, appearing in the simplest form of the semi-empirical mass formula. The surface enery has an influence on e.g. the shape of a nucleus and its ability to deform. This in turn could be expected to have an effect in fusion reactions around the Coulomb barrier where dynamical effects such as the formation of a neck is part of the fusion process. Frozen Hartree-Fock and Time-Dependent Hartree-Fock calculations are made for a series of effective interactions in which the surface energy is systematically varied, using $^{40}$Ca + $^{48}$Ca as a test case. The dynamical lowering of the barrier is greatest for the largest surface energy, contrary to naive expectations, and we speculate that this may be due to the variation in other nuclear matter properties for these effective interactions

description: Electron energy-loss spectrometry was employed to measure the white lines at the L23 absorption edges of the 3d transition-metal oxides and lithium transition-metal oxides. The white-line ratio (L3/L2) was found to increase between d^0 and d^5 and decrease between d^5 and d^10, consistent with previous results for the transition metals and their oxides. The intensities of the white lines, normalized to the post-edge background, are linear for the 3d transition-metal oxides and lithium transition-metal oxides. An empirical correlation between normalized white-line intensity and 3d occupancy is established. It provides a method for measuring changes in the 3d-state occupancy. As an example, this empirical relationship is used to measure changes in the transition-metal valences of Li_{1-x}Ni_{0.8}Co_{0.2}O_2 in the range of 0 < x < 0.64. In these experiments the 3d occupancy of the nickel ion decreased upon lithium deintercalation, while the cobalt valence remained constant.

description: The effect of the non-extensive form of statistical mechanics proposed by Tsallis on the formation of a quark-gluon plasma (QGP) has been recently investigated in ref. \cite{1}. The results show that for small deviations ($\approx 10%$) from Boltzmann-Gibbs (BG) statistics in the QGP phase, the critical temperature for the formation of a QGP does not change substantially for a large variation of the chemical potential. In the present effort we use the extensive $κ$-deformed statistical mechanics constructed by Kaniadakis to represent the constituents of the QGP and compare the results with ref. [1].

Live Rural / Work Rural : Design for Resiliency in Hermitage, NL
Creators: name: Case, Graham
Publisher: name: The University of British Columbia
Year: 2021

description: Rural communities in Newfoundland and Labrador are discovering new economic life through aquaculture. This burgeoning economy provides potential for growth and diversity; however, this potential is inhibited by a shortage of housing, an aging population and a lack of infrastructure for business development. This makes it unlikely that new families will move into these areas creating problems for social and economic resiliency. What we can foresee is, though these towns are thriving now, without an influx of new, younger residents, the current economic spike is likely to be short-lived. Using the community of Hermitage as a testing site, this thesis proposes an architecturally based solution to the problem of resiliency in rural Newfoundland and Labrador communities. A live/work area within the community can act as a stimulus for new growth, providing much needed housing, on-site space for micro-local economic development, and shared community space for new and existing residents.

The results are based on the recent data reported by the L3 Collaboration at CERN LEP. Due to the stringent limit of the model mixing angle $ϕ$, the effect of this angle on the dipole moments is quite small.

description: A new type aporphine-benzylisoquinoline alkaloid leptofumarine (1) was isolated from Leptopyrum fumarioides L. The structure of 1 was elucidated based on spectroscopic evidence. Leptofumarine together with the previously isolated leptopyrine (2) were evaluated for their effect on macrophages and bone marrow (BM) cells in vitro. Both alkaloids inhibited cytokine production by LPS-stimulated peritoneal macrophages. Leptopyrine suppressed osteoclast and osteoblast formation, while leptofumarine affected only osteoblastogenesis.

description: A new regime in the interaction of a two-colour ($ω$,$2ω$) laser with a nanometre-scale foil is identified, resulting in the emission of extremely intense, isolated attosecond pulses - even in the case of multi-cycle lasers. For foils irradiated by lasers exceeding the blow-out field strength (i.e. capable of fully separating electrons from the ion background), the addition of a second harmonic field results in the stabilization of the foil up to the blow-out intensity. This is then followed by a sharp transition to transparency that essentially occurs in a single optical cycle. During the transition cycle, a dense, nanometre-scale electron bunch is accelerated to relativistic velocities and emits a single, strong attosecond pulse with a peak intensity approaching that of the laser field.

description: Two previously undescribed limonoids, 1-O-benzoyl-3-O-deactylnimbolinin C (1) and a pair of epimers named toosendalactonins A and B (12a and 12b), together with ten known compounds (2−11) were isolated from the fruits of Melia azedarach L. Their structures were determined by extensive spectroscopic methods, including 1D-, 2D-nuclear magnetic resonance, and mass spectrometry. All the isolated compounds were evaluated for their nitric oxide (NO) inhibition in lipopolysaccharide-activated microglia and nerve growth factor (NGF) production in astrocytes. Compounds 1−2 and 5−8 significantly inhibited NO production, which is comparable to the positive control, L-NMMA. Previously undescribed limonoid, compound 12, and two known limonoids, munronin K (3) and 12-O-methyl-1-O-deacetyl-nimbolinin B (4), showed the highest potency to increase the NGF production in C6 astrocytes.

description: We study non-crossing frameworks in the plane for which the classical reciprocal on the dual graph is also non-crossing. We give a complete description of the self-stresses on non-crossing frameworks whose reciprocals are non-crossing, in terms of: the types of faces (only pseudo-triangles and pseudo-quadrangles are allowed); the sign patterns in the self-stress; and a geometric condition on the stress vectors at some of the vertices. As in other recent papers where the interplay of non-crossingness and rigidity of straight-line plane graphs is studied, pseudo-triangulations show up as objects of special interest. For example, it is known that all planar Laman circuits can be embedded as a pseudo-triangulation with one non-pointed vertex. We show that if such an embedding is sufficiently generic, then the reciprocal is non-crossing and again a pseudo-triangulation embedding of a planar Laman circuit. For a singular (i.e., non-generic) pseudo-triangulation embedding of a planar Laman circuit, the reciprocal is still non-crossing and a pseudo-triangulation, but its underlying graph may not be a Laman circuit. Moreover, all the pseudo-triangulations which admit a non-crossing reciprocal arise as the reciprocals of such, possibly singular, stresses on pseudo-triangulation embeddings of Laman circuits. All self-stresses on a planar graph correspond to liftings to piece-wise linear surfaces in 3-space. We prove characteristic geometric properties of the lifts of such non-crossing reciprocal pairs.

We provide a Lie-theoretic classification of these objects by studying the interaction between Klyachko's fan filtration and the fiber of the co-Higgs bundle at a closed point in the open orbit of the torus action. This can be interpreted, under certain conditions, as the construction of a coarse moduli scheme of toric co-Higgs bundles of any rank and with any total equivariant Chern class.

description: We present a large homogeneous set of stellar parameters and abundances across a broad range of metallicities, involving $13$ classical dwarf spheroidal (dSph) and ultra-faint dSph (UFD) galaxies. In total this study includes $380$ stars in Fornax, Sagittarius, Sculptor, Sextans, Carina, Ursa Minor, Draco, Reticulum II, Bootes I, Ursa Major II, Leo I, Segue I, and Triangulum II. This sample represents the largest, homogeneous, high-resolution study of dSph galaxies to date. With our homogeneously derived catalog, we are able to search for similar and deviating trends across different galaxies. We investigate the mass dependence of the individual systems on the production of $α$-elements, but also try to shed light on the long-standing puzzle of the dominant production site of r-process elements. We use data from the Keck observatory archive and the ESO reduced archive to reanalyze stars from these $13$ dSph galaxies. We automatize the step of obtaining stellar parameters, but run a full spectrum synthesis to derive all abundances except for iron. The homogenized set of abundances yielded the unique possibility to derive a relation between the onset of type Ia supernovae and the stellar mass of the galaxy. Furthermore, we derived a formula to estimate the evolution of $α$-elements. Placing all abundances consistently on the same scale is crucial to answer questions about the chemical history of galaxies. By homogeneously analysing Ba and Eu in the 13 systems, we have traced the onset of the s-process and found it to increase with metallicity as a function of the galaxy's stellar mass. Moreover, the r-process material correlates with the $α$-elements indicating some co-production of these, which in turn would point towards rare core-collapse supernovae rather than binary neutron star mergers as host for the r-process at low [Fe/H] in the investigated dSph systems.

Against the Ultimate Spinach

description: Scattered throughout the Strait of Georgia, which separates Vancouver Island from mainland British Columbia, are the province’s Gulf Islands. These are sites of extreme endemism and cultural diversity. One such place, at the northern end of this fragmented chain, is Hornby Island. A longstanding arts hub initially characterized by the creative energies of draft dodgers, counter culturalists and hippie intelligentsia who flocked to the island in the ’60s. Part rebellion, part escapist reformation, Hornby Island’s arts culture stands apart from others in the Gulf Islands in that it encompasses both the traditional fine arts and numerous unorthodox architectural explorations. Yet, today the island’s popularity as a tourist destination and the ever-increasing ease of access to its shores risks overtaking the memory and methods of the people who helped develop it. As established artisans age and pass on; and property values continue to rise, limiting entry for their successors, a void begins to grow that risks the erosion of localized cultural and craft memory in its vital role as a touchstone of this rural community. In an effort to contravene such a decline this project proposes a series of speculative design interventions intimately informed by local cultural practices and material ecologies. These constructs positing that the preservation of craft knowledge and freedom of action on the island is as much about one’s agency in the creation of their space as it is in the creation of their art.

description: The quark number susceptibility, associated with the conserved quark number density, is closely related to the baryon and charge fluctuations in the quark-gluon plasma, which might serve as signature for the quark-gluon plasma formation in ultrarelativistic heavy-ion collisions. Beside QCD lattice simulations, the quark number susceptibility has been calculated recently using a resummed perturbation theory (Hard Thermal Loop resummation). In the present work we show, based on general arguments, that the computation of this quantity neglecting Hard Thermal Loop vertices contradicts the Ward identity and violates the thermodynamic sum rule following from the quark number conservation. We further show that the Hard Thermal Loop perturbation theory is consistent with the thermodynamic sum rule.

description: Statistical abstracts have always formed a core source of statistical information for a wide variety of users. The increasing technological capabilities of online media has led to an interest in understanding how statistical abstracts might be adapted or transformed in the age of the Web. This paper reports on a study in which the Delphi technique was used to develop a consensus among a set of experts on the future of one particular abstract: Sourcebook of Criminal Justice Statistics. Participant input was used to generate a mission statement for the Sourcebook and a prioritized list of requirements for accomplishing the mission. The findings indicate a continuing role for the statistical abstract but one that can better utilize technologies to create more personalized statistical displays as well as enhanced access to additional sources.

description: Olea europaea L. leaves and fruits contain several constituents with considerablepharmacological activities. The present study was designed to evaluate theantifungal activity of Lebanese olive against five strains of Candida albicansisolated in a Lebanese hospital. Olive leaves and pomace (cake) samples from threedifferent locations were gathered and extracted differently to obtain threecategories of extracts: ethanolic, cold aqueous and hot aqueous. The antifungalactivity of these extracts was tested using well-diffusion method with averageinhibition zone diameter that reached 27 mm. Two out of the tested extracts; coldaqueous extract of Akkar s cake and ethanolic extracts from Koura s leaves,showed antifungal activity against the growth of all isolates under investigation,with the lowest recorded MIC and MFC of 2.5 and 15 mg/ml, respectively for bothextracts. The time kill assay showed that fungal cells died within 6 hours after theirtreatment with both selected extracts and the decimal reduction time (D-value)determined was 71-72 mins. Total phenolic content was found to be 98.03 GAEmg/g dry matter for ethanolic extracts of leaves from Koura and 91.76 GAE mg/gdry matter for cold aqueous extracts of cake from Akkar, which explains theirfungicidal actions and superiority among other tested extracts. The ultrastucture oftreated Candida albicans with the two selected extracts revealed the presence ofdeformed cells with disintegrated protoplasm and even ruptured cell wall and cellmembrane.

description: We present Ditto, a novel entity matching system based on pre-trained Transformer-based language models. We fine-tune and cast EM as a sequence-pair classification problem to leverage such models with a simple architecture. Our experiments show that a straightforward application of language models such as BERT, DistilBERT, or RoBERTa pre-trained on large text corpora already significantly improves the matching quality and outperforms previous state-of-the-art (SOTA), by up to 29% of F1 score on benchmark datasets. We also developed three optimization techniques to further improve Ditto's matching capability. Ditto allows domain knowledge to be injected by highlighting important pieces of input information that may be of interest when making matching decisions. Ditto also summarizes strings that are too long so that only the essential information is retained and used for EM. Finally, Ditto adapts a SOTA technique on data augmentation for text to EM to augment the training data with (difficult) examples. This way, Ditto is forced to learn "harder" to improve the model's matching capability. The optimizations we developed further boost the performance of Ditto by up to 9.8%. Perhaps more surprisingly, we establish that Ditto can achieve the previous SOTA results with at most half the number of labeled data. Finally, we demonstrate Ditto's effectiveness on a real-world large-scale EM task. On matching two company datasets consisting of 789K and 412K records, Ditto achieves a high F1 score of 96.5%.

description: Two tunnel-coupled few-electron quantum dots were fabricated in a GaAs/AlGaAs quantum well. The absolute number of electrons in each dot could be determined from finite bias Coulomb blockade measurements and gate voltage scans of the dots, and allows the number of electrons to be controlled down to zero. The Zeeman energy of several electronic states in one of the dots was measured with an in-plane magnetic field, and the g-factor of the states was found to be no different than that of electrons in bulk GaAs. Tunnel-coupling between dots is demonstrated, and the tunneling strength was estimated from the peak splitting of the Coulomb blockade peaks of the double dot.

description: $SU(2)_L \times SU(2)_R$ gauge symmetry requires three right-handed neutrinos ($ N _i $), one of which, $N_1$, can be sufficiently stable to be dark matter. In the early universe, $ W _R $ exchange with the Standard Model thermal bath keeps the right-handed neutrinos in thermal equilibrium at high temperatures. $N_1$ can make up all of dark matter if they freeze-out while relativistic and are mildly diluted by subsequent decays of a long-lived and heavier right-handed neutrino, $N_2$. We systematically study this parameter space, constraining the symmetry breaking scale of $SU(2)_R$ and the mass of $N_1$ to a triangle in the $(v_R,M_1)$ plane, with $v_R = (10^6 - 3 \times 10^{12})$ GeV and $M_1 = (2\, {\rm keV} - 1 \, {\rm MeV)}$. Much of this triangle can be probed by signals of warm dark matter, especially if leptogenesis from $N_2$ decay yields the observed baryon asymmetry. The minimal value of $v_R$ is increased to $10^8 \, {\rm GeV}$ for doublet breaking of $SU(2)_R$, and further to $10^9 \, {\rm GeV}$ if leptogenesis occurs via $N_2$ decay, while the upper bound on $M_1$ is reduced to 100 keV. In addition, there is a component of hot $N_1$ dark matter resulting from the late decay of $N_2 \rightarrow N_1 \ell^+ \ell^-$ that can be probed by future cosmic microwave background observations. Interestingly, the range of $v_R$ allows both precision gauge coupling unification and the Higgs Parity understanding of the vanishing of the Standard Model Higgs quartic at scale $v_R$. Finally, we study freeze-in production of $N_1$ dark matter via the $W_R$ interaction, which allows a much wider range of $(v_R,M_1)$.

description: Detailed description of the technical and domain business-specific KPIs that will be used for validating the MUSKETEER data platform. The deliverable D2.3 - Key performance indicators selection and definition, is the first result of the task T2.3. This task deals with the definition of KPIs related to the processing and analysis of data coming from the 2 industrial scenarios, which shall be improved through the application of MUSKETEER data platform. This task will provide to the validation work package with the expected outcomes, which shall be compared with the real results of the validation activities in order to assess the success of the project. The Evaluation Framework employed for validating the MUSKETEER platform, is based on the Goal Question Metric (GQM) method. Thus, measurement goals, questions and metrics are described to the use case implementations towards final evaluation execution by the end of the project. This document describes the planning and the definition phases, which have been achieved at this stage of the project. A revision of the KPIs and methodology will be done in M24. Starting from the final version of the D2.3, Data Collection and interpretation phases will be documented in the deliverables D7.5 and D7.6, where the description of the Smart Manufacturing and Health pilots setup and execution, together with the evaluation of the KPIs, will be reported in order to assess the usage of the MUSKETEER platform.
