description: We compute the phase diagram of a one-dimensional model of spinless fermions with pair-hopping and nearest-neighbor interaction, first introduced by Ruhman and Altman, using the density-matrix renormalization group combined with various analytical approaches. Although the main phases are a Luttinger liquid of fermions and a Luttinger liquid of pairs, we also find remarkable phases in which only a fraction of the fermions are paired. In such case, two situations arise: either fermions and pairs coexist spatially in a two-fluid mixture, or they are spatially segregated leading to phase separation. These results are supported by several analytical models that describe in an accurate way various relevant cuts of the phase diagram. Last, we identify relevant microscopic observables that capture the presence of these two fluids: while originally introduced in a phenomenological way, they support a wider application of two-fluid models for describing pairing phenomena.

description: We perform the first study of the principal core $g$-mode oscillation in hybrid stars containing quark matter, utilizing a crossover model for the hadron-to-quark transition inspired by lattice QCD. The ensuing results are compared with our recent findings of $g$-mode frequencies in hybrid stars with a first-order phase transition using Gibbs constructions. We find that models using Gibbs construction yield $g$-mode amplitudes and the associated gravitational energy radiated that dominate over those of the chosen crossover model owing to the distinct behaviors of the equilibrium and adiabatic sound speeds in the various models. Based on our results, we conclude that were $g$-modes to be detected in upgraded LIGO and Virgo detectors it would indicate a first-order phase transition akin to a Gibbs construction.

description: With the deregulation of the economy and marketing arrangements in Australia, there are a number of instances where a particular industry or section of an industry has adopted a successful collaborative approach to the export or domestic marketing of their produce. The studies of collaborative marketing groups discussed here suggest that while addressing and defining the marketing issues is important, it appears that establishing a suitable structure that can encourage and reward commitment while coping with expansion and changing needs is equally important to success. Careful consideration needs to be given to the ramifications of compulsory and voluntary product contribution. We found that groups tended to avoid formal planning processes but are unsure of the effects this had on success. Despite the importance of leadership to the success of the group, members tended to believe that leaders were bom and not made and therefore most did not have processes in place to encourage development of leadership skills.

description: The implementation of plans normally results in deviations between actual performance and budgeted expectations. Changes in the environment and new information make adjustments to the plan through time necessary for expansion or contraction of the size of a business or parts of it. This is necessary to survive or grow to reach the objectives of the organisation. This paper discusses an integrated control system on an intensive egg production unit. Advanced monitoring techniques such as a global positioning system (GPS), a computerised grading and monitoring (control) system, etc. are discussed in this paper.

description: We report on the growth and properties of high quality bicolor oxide superlattices, composed of two perovskites out of BaTiO3, CaTiO3, and SrTiO3. The artificially grown superlattices are structurally unique and have a macroscopically homogeneous phase, which is not feasible to recreate in bulk form. By artificial structuring, it is found that the polarization of such superlattices can be highly increased as compared to pseudo-binary ceramics with the same overall composition. Such strong enhancement in superlattice is attributed to newly-developed ionic motions of A-site cations at the hetero-interfaces due to the interfacial coupling of electrostatic and elastic interactions, which cannot be found in single phase materials.

description: The scandium modified aluminium alloy Scalmalloy® is specifically developed for the use in laser‐based powder bed fusion (PBF‐LB). It is supposed to show potential in the production of lightweight structures due to its high specific strength compared to other aluminium alloys. A limiting factor is the high surface roughness of additively manufactured parts, which has a negative influence on its mechanical properties, especially under cyclic loads. In order to reduce the surface roughness, methods of design of experiments (DoE) are applied to develop contour parameters. Additionally, the formation of pores in keyhole‐mode welding and strategies to reduce the porosity in the contour area are investigated. The surface roughness of vertical walls can be reduced down to Ra < 7 μm using contour scans with a line energy EL >0.9 J mm⁻¹ but keyhole pores start to form applying EL >0.6– 0.75 J mm⁻¹. Two contour parameter sets in different EL‐ranges are developed that can be used to reduce the surface roughness compared to parameter sets without contour scans, without increasing the porosity in the contour area. Their impact on the mechanical properties has to be further investigated.

description: One of the major developments in Israeli citrus growing in recent years has been the increase in production of Sunrise grapefruit. This process entailed massive capita! investment from private as well as public resources during a time period of about 20 years. Fxport quantities of Sunrise are still increasing while prices declined substantially since the mid-80's. We are evaluating the investment decisions by comparing the investment in planting Sunrise to keeping an existing grove of white grapefruit. Our main findings are- (1) About one third of Sunrise plantations planted in the first part of the two decade period gained a positive and high Net Present Value, while the other two thirds planted later may end up with a very low or even negative NPV; (2) A variation of the product life cycle concept is identified in the development of Sunrise export sales. In the basic PLC concept sales volume and profits develop more or less parallel over lime, while in Sunrise exports the time series of sales is delayed in comparison to profits; (3) These findings are explained by the perennial nature of citrus production with its long time lag from investment til! the start of production.

description: We investigate carrier transport in a single 22 nm-thick double-gated Si quantum well device, which has independent contacts to electrons and holes. Conductance, Hall density and Hall mobility are mapped in a broad double-gate voltage window. When the gate voltage asymmetry is not too large only either electrons or holes occupy the Si well and the Hall mobility shows the fingerprints of volume inversion/accumulation. At strongly asymmetric double-gate voltage an electric field induced electron-hole (EH) bi-layer is formed inside the well. The EH drag resistance R_{he} is explored at balanced carrier densities: R_{he} decreases monotonically from 860 to 37 Ohms when the electron and hole density is varied between ~0.4-1.7x10^{16} m^{-2}.

description: Basis set convergence of correlation effects on molecular atomization energies beyond the CCSD (coupled cluster with singles and doubles) approximation has been studied near the one-particle basis set limit. Quasiperturbative connected triple excitations, (T), converge more rapidly than $L^{-3}$ (where $L$ is the highest angular momentum represented in the basis set), while higher-order connected triples, $T_3-(T)$, converge more slowly -- empirically, $\propto L^{-5/2}$. Quasiperturbative connected quadruple excitations, (Q), converge smoothly as $\propto L^{-3}$ starting with the cc-pVTZ basis set, while the cc-pVDZ basis set causes overshooting of the contribution in highly polar systems. Higher-order connected quadruples display only weak, but somewhat erratic, basis set dependence. Connected quintuple excitations converge very rapidly with the basis set, to the point where even an unpolarized double-zeta basis set yields useful numbers. In cases where fully iterative CCSDTQ5 (coupled cluster up to connected quintuples) calculations are not an option, CCSDTQ(5) (i.e., coupled cluster up to connected quadruples plus a quasiperturbative connected quintuples correction) cannot be relied upon in the presence of significant nondynamical correlation, whereas CCSDTQ(5)$_Λ$ represents a viable alternative. Connected quadruples corrections to the core-valence contribution are thermochemically significant in some systems. [...] We conclude that ``$3σ\leq 1$ kJ/mol'' thermochemistry is feasible with current technology, but that the more ambitious goal of $\pm$10 cm$^{-1}$ accuracy is illusory, at least for atomization energies.

On the influence of time and space correlations on the next earthquake magnitude

description: A crucial point in the debate on feasibility of earthquake prediction is the dependence of an earthquake magnitude from past seismicity. Indeed, whilst clustering in time and space is widely accepted, much more questionable is the existence of magnitude correlations. The standard approach generally assumes that magnitudes are independent and therefore in principle unpredictable. Here we show the existence of clustering in magnitude: earthquakes occur with higher probability close in time, space and magnitude to previous events. More precisely, the next earthquake tends to have a magnitude similar but smaller than the previous one. A dynamical scaling relation between magnitude, time and space distances reproduces the complex pattern of magnitude, spatial and temporal correlations observed in experimental seismic catalogs.

description: We generalize and test the recent "ab initio" self-consistent (AISC) time-independent semiclassical laser theory. This self-consistent formalism generates all the stationary lasing properties in the multimode regime (frequencies, thresholds, internal and external fields, output power and emission pattern) from simple inputs: the dielectric function of the passive cavity, the atomic transition frequency, and the transverse relaxation time of the lasing transition. We find that the theory gives excellent quantitative agreement with full time-dependent simulations of the Maxwell-Bloch equations after it has been generalized to drop the slowly-varying envelope approximation. The theory is infinite order in the non-linear hole-burning interaction; the widely used third order approximation is shown to fail badly.

description: There is an increasing demand for quality assurance (QA) in food supplied hy farmers. In response, farmer organisations have been developing on-farm quality assurance schemes such as Cattlecarefor cattle (1995) andFlockcare for sheep (1997). However the adoption of these schemes has been slow. Research in 1998 investigated the impediments to adoption. Because Flockcare was new and relatively unknown, the research was based on in-depth interviews about Cattlecare. Impediments to Cattlecare adoption included the need for extra record keeping, additional costs, adversarial industry relationships, a lack of conviction that QA was consumer driven, no obvious benefits to farmers, no sense of urgency, and no obvious trigger for action.

description: Integrated optoelectronics is emerging as a promising platform of neural network accelerator, which affords efficient in-memory computing and high bandwidth interconnectivity. The inherent optoelectronic noises, however, make the photonic systems error-prone in practice. It is thus imperative to devise strategies to mitigate and, if possible, harness noises in photonic computing systems. Here, we demonstrate a photonic generative network as a part of a generative adversarial network (GAN). This network is implemented with a photonic core consisting of an array of four programable phase-change memory cells to perform 4-elements vector-vector dot multiplication. We demonstrate that the GAN can generate a handwritten number ("7") in experiments and full ten digits in simulation. We realize an optical random number generator derived from the amplified spontaneous emission noise, apply noise-aware training by injecting additional noise and demonstrate the network's resilience to hardware non-idealities. Our results suggest the resilience and potential of more complex photonic generative networks based on large-scale, realistic photonic hardware.

The aim of this research is to understand better how users choose among social networking sites as an act of brand identification. The study presents a new model whose structure of identification drivers for social networking brand sites varies for customer brand identification in the real and virtual worlds. The presented model reveals that personal branding is a planned effect of brand identification and it is crucial for brand value creation in social networks.

description: We investigate the dynamics of football matches. Our goal is to characterize statistically the temporal sequence of ball movements in this collective sport game, searching for traits of complex behavior. Data were collected over a variety of matches in South American, European and World championships throughout 2005 and 2006. We show that the statistics of ball touches presents power-law tails and can be described by $q$-gamma distributions. To explain such behavior we propose a model that provides information on the characteristics of football dynamics. Furthermore, we discuss the statistics of duration of out-of-play intervals, not directly related to the previous scenario.

description: Worldwide, the ISO 9000 quality assurance standards have received considerable support from firms seeking to improve their economic competitiveness. This paper focusses on South African agribusiness firms ’ experiences with the ISO 9000 standards. A postal survey was conducted amongst 92 agribusiness firms to determine the extent of adoption of ISO 9000, reasons for certification atul to identify the costs and benefits of adopting these standards. About 36 percent of respondent firms were certified. The desire to improve customer service, a basis for quality improvement and the need to improve operational efficiency (reduce wastage) were the most important factors influencing certification. Respondents reportedfinancial, managerial and production benefits following certification. Discriminant analysis revealed that ISO 9000 certified firms tended to be larger, established firms with parent company affiliation, manufacturing products derived from agricultural output and exporting to developed countries. Most non-certified firms had adopted an alternative quality assurance system.

Comments
One of the most widespread and well-documented species of Strumigenys in Asia, with its geographical range including central to northern provinces of mainland China (as far as Beijing) and North Korea, which are often void of any record of Strumigenys. Its presence in Chinese provinces such as Hainan, Hebei, Henan, Anhui, Jiangxi is likely. Records from Myanmar need confirmation (Bolton 2000), while past records from India have been excluded (Bharti et al. 2016). Similarly, several records of this species outside its native range such as in Malta and Georgia in Europe most likely represent misidentifications (Hamer et al. 2021). Records from the Philippines (Way et al. 1998) would also need to be confirmed.

description: Total production value for seeds and propagation material in the Netherlands in 1994 equals 640 million Euro, approximately 6% of world production value. The organisation of the industry is continuously changing. To predict developments in this industry, we performed desk-research and asked managers about their response on the development of important socio-economic factors: With these developments in mind, companies have to develop a global strategy:
Shareholders value is related to availability of patents, access to genetic sources and efficiency in which markets can be opened up and maintained. Besides this strategy the following will occur.
. Economies of scale are important. Mergers or buy-outs will continuously occur. Local activities will be managed from a headquarter, located in the USA, Europe or Japan.

description: An efficient futures market should provide a forecast of the future spot (cash) price which reflects all publicly available information; ideally, for effective price discovery, such forecasts would also be unbiased The trading of yellow maize futures contracts began in South Africa in mid-J996 after the power of the Maize Board to set maize producer prices was abolished Cointegration analysis shows that (I) there is a long-run relationship between South African yellow maize futuresand spot prices, and (2) the futures price was cm unbiased predictor of spot prices for the three-month 1997 contract and annual 1998 contract, but a biased predictor for the three-month 1998 contract. Overall, this means that South African maize farmers can use price information derived from recently introduced yellow maize futures contracts to forecast "local" yellow maize cash prices. This information can help them in their planting decisions, in negotiating yellow maize cash prices with traders and millers, and in deciding whether, and what portion of their crop, to hedge against price risk by using futures contracts.

description: Using state-of-the-art adaptive mesh refinement cosmological hydrodynamic simulations with a spatial resolution of proper 0.21kpc/h in refined subregions embedded within a comoving cosmological volume (27.4Mpc/h)^3, we investigate the sizes of galaxies at z=3 in the standard cold dark matter model where reionization is assumed to complete at zri~6. Our simulated galaxies are found to be significantly smaller than the observed ones: while more than one half of the galaxies observed by HST and VLT ranging from rest-frame UV to optical bands with stellar masses larger than 2E10 Msun have half-light radii larger than 2kpc/h, none of the simulated massive galaxies in the same mass range have half-light radii larger than 2kpc/h, after taking into account dust extinction. Corroborative evidence is provided by the rotation curves of the simulated galaxies with total masses of 1E11-1E12Msun, which display values 300-1000km/s at small radii (0.5kpc/h) due to high stellar concentration in the central regions, larger than those of any well observed galaxies. Possible physical mechanisms to resolve this serious problem include: (1) an early reionization at zri>>6 to suppress gas condensation hence star formation, (2) a strong, internal energetic feedback from stars or central black holes to reduce the overall star formation efficiency, or (3) a substantial small-scale cutoff in the matter power spectrum.

description: The implantation and development of new methods aimed to assess the health status of coral reefs is a tenet core for the conservation science of these systems. For years, coral reefs communities have been described in Venezuela; however, no efforts to classify the health status of these systems have been accomplished. Part of the problem is that reefs have being always classified in terms of live coral cover, while other variables clearly linked with healthy reefs have been neglected. In this work, we aimed to assess the health status of 36 reef sites encompassing seven different geographical locations in Venezuela using a multivariate approach.
Vertical distribution and biomass of fine roots in three subalpine forest plant associations in southwestern British Columbia
Creators: name: Nuszdorfer, Friedrich Carl
Publisher: name: University of British Columbia
Year: 2010

description: Roots smaller than 5 mm in diameter were studied in three typical high elevation forested plant associations of coastal Southwestern British Columbia. The objectives were to quantify their distribution with depth, examining changes with plant association and time; to examine their relationships with foliage; and to seek correlations with soil properties. Coring randomly in three replicates of each plant association was followed by washing of soil and organic matter from roots with water in combination with manual sorting. Length and surface area were estimated for all samples. Standard analytical methods were used for determining soil physical and chemical properties. Soil temperature and moisture were measured during the growing season. The peak in mass of both overstory and understory < 2 mm roots was within the upper 10 cm of the soil. Overstory 2-5 mm roots peaked between 5 and 30 cm. Understory 2-5 mm roots peaked within 10 cm of the surface of the forest floor. The large variation between replicates of the plant associations made it impossible to determine if changes in root mass with time of sampling were real or due to random variation. Unsuberized roots of the overstory vegetation contributed very little to biomass of ≤ 5 mm roots. Biomass of ≤ 5 mm roots of the overstory vegetation varied from 740 to 1320 g m⁻², length from 3.8 to 6.5 km m⁻², and surface area from 7.3 to 11.9 m² m⁻². The ridgetop association had the most overstory and understory roots and its soil (including organic horizons) was lowest in total nitrogen concentration and CEC. The midslope association had intermediate amounts of overstory roots, the lowest amount of understory roots, and its soil was intermediate in nitrogen concentration and CEC. The receiving association had the lowest amounts of overstory roots, intermediate amounts of understory roots, and its soil had the highest nitrogen concentration and CEC. The ridgetop ecosystems had the highest ratio of root-to-shoot and ratio of root-to-foliage plus twig, being approximately double the ratio for the receiving association. The midslope association was intermediate. Correlations of root mass with soil properties were generally poor.

description: The low-temperature behavior of Ce2RuZn4 has been investigated. Specific heat and magnetic susceptibility data reveal an antiferromagnetic transition at a Neel temperature of 2 K. Ce2RuZn4 is a static intermediate-valent compound with two crystallographically independent cerium atoms. The magnetic data clearly show that only one cerium site is magnetic (Ce^3+), while the second one carries no magnetic moment. The experimental data are interpreted with the help of first principles electronic structure calculations using density functional theory and the augmented spherical wave method. The calculations reveal the occurrence of two different cerium sites, which are characterized by strongly localized magneticmoments and strong Ce-Ru bonding, respectively.

description: We apply the Lagrange-mesh $R$-matrix method to calculate the $S$-factor for the $^{13}$C$(p,γ)^{14}$N and $^{16}$O$(p,γ)^{17}$F direct radiative capture reactions. By comparing the astrophysical $S$-factors calculated with nonlocal and local potentials, we investigate the nonlocality effects coming from the nuclear potentials in the direct capture reactions. Our calculations are in good agreement with the experimental data and indicate a nonnegligible difference in the results of local and nonlocal potentials. The use of small diffuseness narrow potentials also provides a remarkably good fit in the case with multiple broad resonances. Our findings suggest that the nonlocal potential improves the calculated results although the difference between the local and nonlocal potentials is smaller than uncertainties from other sources. We propose the nonlocality potential should be used in the potential model calculation of future astrophysics rates evaluation.

A generalized Petviashvili iteration method for scalar and vector Hamiltonian equations with arbitrary form of nonlinearity
Creators: name: Lakoba, T. I.

Year: 2007
Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: The Petviashvili's iteration method has been known as a rapidly converging numerical algorithm for obtaining fundamental solitary wave solutions of stationary scalar nonlinear wave equations with power-law nonlinearity: \ $-Mu+u^p=0$, where $M$ is a positive definite self-adjoint operator and $p={\rm const}$. In this paper, we propose a systematic generalization of this method to both scalar and vector Hamiltonian equations with arbitrary form of nonlinearity and potential functions. For scalar equations, our generalized method requires only slightly more computational effort than the original Petviashvili method.

description: Organizations can lose knowledge as fast as they can create it. Retiring Baby Boomers, job-hopping Millennials and out-of-date communication and collaboration practices contribute to organizational knowledge loss. This knowledge loss costs organizations billions of dollars for re-learning and for hiring, onboarding and training new employees. Knowledge management strategies foster knowledge retention and are critical to facilitating innovation. Knowledge management can be enhanced using collaborative technologies such as enterprise wikis, instant messaging, collaborative writing, project management, blockchain and semantic web technologies powered by artificial intelligence. Through a systematic review and synthesis of 46 critically appraised studies that span global contexts and sectors, this dissertation informs scholars and practitioners by providing evidence and recommendations to global organizations looking to implement, adopt or utilize collaborative technologies to retain knowledge, prevent knowledge loss or establish and strengthen an organizational culture that fosters knowledge management. Through thematic synthesis and qualitative analysis of inductive codes across scholarly articles, this research highlights aspects of affordances (access to knowledge, knowledge sharing across organizational boundaries, searchability) and organizational culture (knowledge sharing culture, transparency, the role of management) as keys to strategically leverage collaborative technologies for knowledge management. Organizations can retain their knowledge and build innovative capacity by systematically adopting and implementing collaborative technologies. By fostering transparency and knowledge sharing across boundaries, encouraging managers and leaders to promote a collaborative and transparent culture, and prioritizing the continued use of these technologies, organizations can maximize their knowledge management outcomes.
Effective dislocation lines in continuously dislocated crystals. I. Material anholonomity

description: A continuous geometric description of Bravais monocrystals with many dislocations and secondary point defects created by the distribution of these dislocations is proposed. Namely, it is distinguished, basing oneself on Kondo and Kroners Gedanken Experiments for dislocated bodies, an anholonomic triad of linearly independent vector fields. The triad defines local crystallographic directions of the defective crystal as well as a continuous counterpart of the Burgers vector for single dislocations. Next, the influence of secondary point defects on the distribution of many dislocations is modeled by treating these local crystallographic directions as well as Burgers circuits as those located in such a Riemannian material space that becomes an Euclidean 3-manifold when dislocations are absent. Some consequences of this approach are discussed.

description: We compute the Hamiltonian surface charges of gravity for a family of conservative boundary conditions, that include Dirichlet, Neumann, and York's mixed boundary conditions defined by holding fixed the conformal induced metric and the trace of the extrinsic curvature. We show that for all boundary conditions considered, canonical methods give the same answer as covariant phase space methods improved by a boundary Lagrangian, a prescription recently developed in the literature and thus supported by our results. The procedure also suggests a new integrable charge for the Einstein-Hilbert Lagrangian, different from the Komar charge for non-Killing and non-tangential diffeomorphisms. We study how the energy depends on the choice of boundary conditions, showing that both the quasi-local and the asymptotic expressions are affected. Finally, we generalize the analysis to non-orthogonal corners, confirm the matching between the covariant and canonical results without any change in the prescription, and discuss the subtleties associated with this case.

description: Although the introduction of westernised forms of agriculture to the Australian continent has led to national development and created economic wealth through major export earnings, these gains have been achieved at a huge cost to the Australian environment. The sustainability of agricultural production systems is now becoming a matter of concern. This paper describes how, in 1992, a postgraduate, distance education program in sustainable agriculture was introduced at Orange Agricultural College to provide educational opportunities for those who wished to develop more sustainable systems of agriculture. The course aims and structure are described. One of the units of study in this program was designed to provide a strategic approach to property planning. This approach, which is being used with farmers and Landcare groups to facilitate the development of more sustainable systems of agriculture, is described. Opportunities for international collaboration are raised.
