description: This paper presents a case study of the Honey Bee Network’s decentralized model for collecting, verifying and disseminating grassroots innovations and provides a roadmap for its replication in Africa. The Honey Bee Network brings together governmental and non‐governmental institutions, members of academia, scholars and a large number of volunteers. Through the Network’s activities, locally-designed solutions and traditional knowledge with the potential to be refined and scaled up are scouted and members of the Network work with the innovators to help their ideas reach their commercial or non‐commercial potential. The Network has been involved in the sharing of grassroots technology developed in India with Kenya, notably a food processing machine, seed sowing device, and a small tractor. Through these pilot programs, actors at the grassroots had a chance to collaborate and co‐design solutions adapted to the Kenyan context. This experience revealed a willingness in Kenya to further invest in grassroots innovation initiatives, and Network members identified many conditions that would make Kenya the right choice for an African network hub, such as a rich traditional knowledge system and institutional willingness and recognition of the dynamism of the informal sector. Lessons from the Network’s experience in Kenya and its technology transfer program are collected and turned into recommendations for the development of a sister Network in Africa.

description: This paper describes a novel approach for on demand volumetric texture synthesis based on a deep learning framework that allows for the generation of high quality 3D data at interactive rates. Based on a few example images of textures, a generative network is trained to synthesize coherent portions of solid textures of arbitrary sizes that reproduce the visual characteristics of the examples along some directions. To cope with memory limitations and computation complexity that are inherent to both high resolution and 3D processing on the GPU, only 2D textures referred to as "slices" are generated during the training stage. These synthetic textures are compared to exemplar images via a perceptual loss function based on a pre-trained deep network. The proposed network is very light (less than 100k parameters), therefore it only requires sustainable training (i.e. few hours) and is capable of very fast generation (around a second for $256^3$ voxels) on a single GPU. Integrated with a spatially seeded PRNG the proposed generator network directly returns an RGB value given a set of 3D coordinates. The synthesized volumes have good visual results that are at least equivalent to the state-of-the-art patch based approaches. They are naturally seamlessly tileable and can be fully generated in parallel.

description: Recent negotiations of the United States Mexico Canada Agreement (USMCA) and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) highlight the impact of contracting costs, uncertainty, and the importance of political welfare. Agriculture exhibits these traits perhaps more than any other sector and subsequently tends to be pivotal in many trade negotiations. Moreover, these traits are -- to some extent -- responsible for the large increase in Regional Trade Agreements (RTAs). In this manuscript we extend the political economy model of trade agreements to include both contracting costs and uncertainty. Uncertainty is incorporated through trade and policy shocks while contracting costs are incorporated as a function of the number of policy instruments. The optimal conditions on domestic support differ considerably if governments maximize social surplus only versus some linear combination of both social surplus and private political welfare. We also show that the politically optimal structure of trade agreements allows for countervailing duties. Our model helps explain: (a) why tariffs rather than production subsidies are more common in agriculture; (b) differential treatment of agricultural producers in developed versus developing countries; (c) continued presence of agricultural subsidies in many RTAs even under significant trade volume growth; and (d) the trend toward harmonization of Sanitary and Phytosanitary Standards (SPS) measures.

description: Using the Ashtekar-Sen variables of loop quantum gravity, a new class of exact solutions to the equations of quantum cosmology is found for gravity coupled to a scalar field, that corresponds to inflating universes. The scalar field, which has an arbitrary potential, is treated as a time variable, reducing the hamiltonian constraint to a time-dependent Schroedinger equation. When reduced to the homogeneous and isotropic case, this is solved exactly by a set of solutions that extend the Kodama state, taking into account the time dependence of the vacuum energy. Each quantum state corresponds to a classical solution of the Hamiltonian-Jacobi equation. The study of the latter shows evidence for an attractor, suggesting a universality in the phenomena of inflation. Finally, wavepackets can be constructed by superposing solutions with different ratios of kinetic to potential scalar field energy, resolving, at least in this case, the issue of normalizability of the Kodama state.

description: The structure of Canadian agriculture sector has changed significantly. There are fewer farms and farmers but the average farm size for those remaining has increased. The extent of the change varies by region and commodity. For example, average farm size has grown more in Saskatchewan than Ontario and the rate of growth is higher for hog farms than for other livestock farms. The growth in the average farm size is driven by an increase in the absolute number of large farms but the growing share of small farms tempers the extent of the increase in average farm size. Regardless of sector, the number of mid-sized farms that dominated production a generation ago has declined significantly. The hollowing out of the middle has resulted in a movement away from a bell-shaped distribution for farm size to a more uniform distribution. Those in the largest size categories consequently represent a growing percentage of total farm sales. In addition to size, which has been the focus of this review, farm structure can also be assessed in terms of by attributes such as specialization, focus, contracts, ownership structure, and markets. These attributes have also changed resulting in a sector with a heterogeneous group of participants. The variation makes it difficult to assess the need for policy action and what should be the focus of any interventions. The growing heterogeneity also suggests that there are different drivers for entry and exit within the sector and that understanding those drivers will help explain the underlying structural changes in agriculture.

description: The average income of farm operator families distributed size of farm business receipts gives a misleading indication of the well-being of farm families. For 1970, the distribution of farm taxpayers by basic income classes varied considerably within as well as between farm receipt classes. Thus, the link between size of farm business and family wellbeing should be considered but a myth.

description: We study combined interference effects due to the Aharonov-Bohm (AB) and Aharonov-Casher (AC) phases in a Josephson supercurrent of local and nonlocal (split) Cooper pairs. We analyze a junction between two superconductors interconnected through a normal-state nanostructure with either (i) a ring, where single-electron interference is possible, or (ii) two parallel nanowires, where the single-electron interference can be absent, but the cross Andreeev reflection can occur. In the low-transmission regime in both geometries the AB and AC effects can be related to only local or nonlocal Cooper pair transport, respectively.

description: In this article, a numerical tool is proposed in the framework of bond-based peridynamics to simulate fatigue crack propagation in composite materials and structures. The cycle-dependent damage-cumulative model derived from Peerlings' law and applied to a bilinear constitutive law is used to evaluate the fatigue degradation of the bond stiffness. Several benchmark cases are studied to validate the proposed approach. Finally, static and fatigue crack propagations in composite systems with single or multi-inclusions are simulated to illustrate the capabilities and characteristics of the developed approach.This article is part of the theme issue ‘Ageing and durability of composite materials’.

description: The inner annular gap (IAG), a new type of inner gap whose magnetic field lines intersect the null charge surface (NCS), is proposed to explain $γ$-ray and radio emission from pulsars. The IAG can be an important source for high-energy particles. The particles can radiate between the NCS and the IAG. Some observational characteristics in both $γ$-ray and radio bands, such as the $γ$-ray emission beams of Crab-like, Vela-like and Geminga-like, can be reproduced by numerical method. It is predicted that the view angle $ζ$ should be larger than the inclination angle ($ζ>α$), otherwise the $γ$-ray radiation will have little possibility to be observed. Whether the inner annular gap (or cap) is sparking (or free flow) depends on the surface binding energy of the pulsar. In stead of neutron star models, the scenario of the IAG is favorable for bare strange star models, because bare strange stars can easily satisfy the requisite condition to form an IAG for both pulsars ($\vecΩ\cdot \vec{B}<0$) and anti-pulsars ($\vecΩ\cdot \vec{B}>0$).

description: Improved understanding of charge-transport in single molecules is essential for harnessing the potential of molecules e.g. as circuit components at the ultimate size limit. However, interpretation and analysis of the large, stochastic datasets produced by most quantum transport experiments remains an ongoing challenge to discovering much-needed structure-property relationships. Here, we introduce Segment Clustering, a novel unsupervised hypothesis generation tool for investigating single molecule break junction distance-conductance traces. In contrast to previous machine learning approaches for single molecule data, Segment Clustering identifies groupings of similar pieces of traces instead of entire traces. This offers a new and advantageous perspective into dataset structure because it facilitates the identification of meaningful local trace behaviors that may otherwise be obscured by random fluctuations over longer distance scales. We illustrate the power and broad applicability of this approach with two case studies that address common challenges encountered in single molecule studies: First, Segment Clustering is used to extract primary molecular features from a varying background to increase the precision and robustness of conductance measurements, enabling small changes in conductance in response to molecular design to be identified with confidence. Second, Segment Clustering is applied to a known data mixture to qualitatively separate distinct molecular features in a rigorous and unbiased manner. These examples demonstrate two powerful ways in which Segment Clustering can aid in the development of structure-property relationships in molecular quantum transport, an outstanding challenge in the field of molecular electronics.

description: We report here on the electronic structure of electron-doped half-metallic ferromagnetic perovskites such Sr$_{2-x}$La$_x$FeMoO$_6$ ($x$=0-0.6) as obtained from high-resolved valence-band photoemission spectroscopy (PES). By comparing the PES spectra with band structure calculations, a distinctive peak at the Fermi level (E$_F$) with predominantly (Fe+Mo) t$_{2g}^\downarrow$ character has been evidenced for all samples, irrespectively of the $x$ values investigated. Moreover, we show that the electron doping due to the La substitution provides selectively delocalized carriers to the t$_{2g}^\downarrow$ metallic spin channel. Consequently, a gradual rising of the density of states at the E$_F$ has been observed as a function of the La doping. By changing the incoming photon energy we have shown that electron doping mainly rises the density of states of Mo parentage. These findings provide fundamental clues for understanding the origin of ferromagnetism in these oxides and shall be of relevance for tailoring oxides having still higher T$_C$.

description: The spin filtering effect of the electron current in a double-barrier resonant-tunneling diode (RTD) consisting of ZnMnSe semimagnetic layers has been studied theoretically. The influence of the distribution of the magnesium ions on the coefficient of the spin polarization of the electron current has been investigated. The dependence of the spin filtering degree of the electron current on the external magnetic field and the bias voltage has been obtained. The effect of the total spin polarization of the electron current has been predicted. This effect is characterized by total suppression of the spin-up component of electron current, that takes place when the Fermi level coincides with the lowest Landau level for spin-up electrons in the RTD semimagnetic emitter.

description: It is argued that Weinberg's approach to the nucleon-nucleon (NN) interaction problem within effective field theory provides a consistent power counting for renormalized diagrams. Within this scheme the NN potential is organized as an expansion in terms of small quantities like small external momenta and the pion mass (divided by the characteristic large scale of the effective theory). Physical observables to any given order in these small quantities are calculated from the solutions of the Lippmann-Schwinger (or Schr\" odinger) equation.

The effect of high birefringence is explored, revealing new dynamics and regions of bistability. It is shown that optical switching of the polarisation states of the lasers may be controlled through the optical pump and that, under certain conditions, the polarisation of one laser may be switched by controlling the intensity and polarisation in the other.

description: Maximal signal and peak of high-frequency relic gravitational waves (GW's), recently expected by quintessential inflationary models, may be firmly localized in the GHz region, the energy density of the relic gravitons in critical units (i.e., $ h_0^2 Ω_{GW}$) is of the order $10^{-6}$, roughly eight orders of magnitude larger than in ordinary inflationary models. This is just right best frequency band of the electromagnetic (EM) response to the high-frequency GW's in smaller EM detecting systems. We consider the EM response of a Gaussian beam passing through a static magnetic field to a high-frequency relic GW. It is found that under the synchroresonance condition, the first-order perturbative EM power fluxes will contain "left circular wave" and "right circular wave" around the symmetrical axis of the Gaussian beam, but the perturbative effects produced by the states of + polarization and $\times$ polarization of the relic GW have different properties, and the perturbations on behavior are obviously different from that of the background EM fields in the local regions. For the high-frequency relic GW with the typical parameters $ ν_g = 10^{10}Hz$, $ h = 10^{- 30} $ in the quintessential inflationary models, the corresponding perturbative photon flux passing through the region $ 10^{- 2} m^{2} $ would be expected to be $ 10^{3}s^{-1} $. This is largest perturbative photon flux we recently analyzed and estimated using the typical laboratory parameters. In addition, we also discuss geometrical phase shift generated by the high-frequency relic GW in the Gaussian beam and estimate possible physical effects.

description: The relationship between auditory comprehension and reading comprehension is close. Essentially, these are two processes based on the same cognitive processes and one is the basis for the development of the other. This paper examined the level of development of auditory comprehension of preschool children and its teaching using narrative texts on the topic of sustainable and Mediterranean nutrition.The study involved 14 preschool children. A pre-intervention test and a post-intervention test were used as a tool to measure their auditory comprehension. The duration of the intervention was two weeks with the implementation of 8 teaching activities aimed at teaching the narrative building blocks and drawing conclusions. In conclusion, with the frequent telling of tales and stories in the classroom but also activities in accordance with the developmental age of the children and based on the Curriculum of the kindergarten, it was achieved to address the difficulties faced by infants in the auditory comprehension of children's texts.

description: We report results of muon spin relaxation and rotation ($μ$SR) experiments on the spin-liquid candidate~YbMgGaO$_{4}$. No static magnetism $\gtrsim 0.003μ_B$ per Yb ion, ordered or disordered, is observed down to 22~mK, a factor of two lower in temperature than previous measurements. Persistent (temperature-independent) spin dynamics are observed up to 0.20~K and at least 1~kOe, thus extending previous zero-field $μ$SR results over a substantial region of the $H$-$T$ phase diagram. Knight shift measurements in a 10-kOe transverse field reveal two lines with nearly equal amplitudes. Inhomogeneous muon depolarization in a longitudinal field, previously characterized by stretched-exponential relaxation due to spatial inhomogeneity, is fit equally well with two exponentials, also of equal amplitudes. We attribute these results to two interstitial muon sites in the unit cell, rather than disorder or other spatial distribution. Further evidence for this attribution is found from agreement between the ratio of the two measured relaxation rates and calculated mean-square local Yb$^{3+}$ dipolar fields at candidate muon sites. Zero-field data can be understood as a combination of two-exponential dynamic relaxation and quasistatic nuclear dipolar fields.

description: The interplay between linearly dispersing or Dirac-like, and flat electronic bands, for instance, in the kagome ferromagnets, has attracted attention due to a possible interplay between topology and electronic correlations. Here, we report the synthesis, structural, electrical, and magnetic properties of a single-crystalline ferromagnetic compound, namely Fe$_{1/3}$CrTe$_2$ or FeCr$_3$Te$_6$, which crystallizes in the $P\bar{3}m1$ space group instead of the $I2/m$ previously reported for FeCr$_2$Te$_4$. Electronic band structure calculations reveal type-II Dirac nodes and relatively flat bands near the Fermi level ($\varepsilon_F$). This compound shows onset Curie temperature $T_{\text{c}}\simeq 120$ K, followed by an additional ferromagnetic transition near $T_{\text{c2}} \sim 92.5 $ K. Below $T_{\text{c}}$, FeCr$_3$Te$_6$ displays a pronounced anomalous Hall effect, as well as sizable coercive fields that exceed $μ_0H = 1$~T at low $T$s. However, a scaling analysis indicates that the anomalous Hall effect results from a significant intrinsic contribution, as expected from the calculations, but also from the extrinsic mechanism, i.e., scattering. The extrinsic contribution probably results from occupational disorder at the 1b Fe-site within the van der Waals gap of the CrTe$_2$ host. We also observe evidence for a topological Hall component superimposed onto the overall Hall response, suggesting the presence of chiral spin textures akin to skyrmions in this centrosymmetric system. Their possible presence will require experimental confirmation.

description: We elaborate further on the evolution properties of cosmological fluctuations through a bounce. We show this evolution to be describable either by ``transmission'' and ``reflection'' coefficients or by an effective unitary S-matrix. We also show that they behave in a time reversal invariant way. Therefore, earlier results are now interpreted in a different perspective and put on a firmer basis.

description: A new solution for general half-plane contact problems subject to a constant normal load together with alternating shear loads and tension in the steady state is presented. The method uses a formulation where a displacement correction is made to the fully stuck contact solution. There will be two outer regions of slip and a central permanent stick zone, which is explicitly established. Thereby, the maximum extent of the slip zones is effectively specified. Cases of small and large tension are studied, that is when the direction of slip is the same or opposing at the ends of the contact, respectively.

 Description
 Shell (Fig. 11A–C). Length up to 2.8 mm; elongate­conic broadly conical (SW/SL 0.45–0.56, mean 0.49, n = 3);spire tall, straight in outline; last whorl evenly rounded, or angular to subangular in middle of whorl; suture grooved/channelled or with very narrow shoulder above or below. Protoconch microsculpture unknown. Teleoconch up to 4.4 whorls in adult; aperture oval to pear­shaped; small, much shorter than spire (AL/SL 0.37– 0.44, mean 0.40, n = 3); outer lip orthocline, straight, with narrow reflection and thickened; notch present in posterior corner of aperture; inner lip thin to moderately thickened and narrow to medium width, in partial contact or narrowly separated from parietal wall.
Dimensions. See Table 5.
 Distribution and habitat
Known only from Persephone Pot, Bauhaus, where it lives in a narrow (about 0.5m wide), slow flowing (estimated about 1L/s) stream. The substrate is composed of cobbles, gravel and silt.
 Remarks
 Pseudotricula elongata has a very distinctive, elongate shell shape and is known only from a few specimens. It is only known from Persephone Pot, where it is found living with several other species (Table 15). It is readily distinguished from all of the other species found in the caves by its large, elongate shell and distinctly sinuate outer lip.

Analysis of hydrogen permeation tests considering two different modelling approaches for grain boundary trapping in iron

description: The electrochemical permeation test is one of the most used methods for characterising hydrogen diffusion in metals. The flux of hydrogen atoms registered in the oxidation cell might be fitted to obtain apparent diffusivities. The magnitude of this coefficient has a decisive influence on the kinetics of fracture or fatigue phenomena assisted by hydrogen and depends largely on hydrogen retention in microstructural traps. In order to improve the numerical fitting of diffusion coefficients, a permeation test has been reproduced using FEM simulations considering two approaches: a continuum 1D model in which the trap density, binding energy and the input lattice concentrations are critical variables and a polycrystalline model where trapping at grain boundaries is simulated explicitly including a segregation factor and a diffusion coefficient different from that of the interior of the grain. Results show that the continuum model captures trapping delay, but it should be modified to model the trapping influence on the steady state flux. Permeation behaviour might be classified according to different regimes depending on deviation from Fickian diffusion. Polycrystalline synthetic permeation shows a strong influence of segregation on output flux magnitude. This approach is able to simulate also the short-circuit diffusion phenomenon. The comparison between different grain sizes and grain boundary thicknesses by means of the fitted apparent diffusivity shows the relationships between the registered flux and the characteristic parameters of traps.

description: We propose and investigate a unifying class of sparse random graph models, based on a hidden coloring of edge-vertex incidences, extending an existing approach, Random graphs with a given degree distribution, in a way that admits a nontrivial correlation structure in the resulting graphs. The approach unifies a number of existing random graph ensembles within a common general formalism, and allows for the analytic calculation of observable graph characteristics. In particular, generating function techniques are used to derive the size distribution of connected components (clusters) as well as the location of the percolation threshold where a giant component appears.

Escaping from nonhyperbolic chaotic attractors

description: We study the noise-induced escape process from chaotic attractors in nonhyperbolic systems. We provide a general mechanism of escape in the low noise limit, employing the theory of large fluctuations. Specifically, this is achieved by solving the variational equations of the auxiliary Hamiltonian system and by incorporating the initial conditions on the chaotic attractor unambiguously. Our results are exemplified with the H{é}non and the Ikeda map and can be implemented straightforwardly to experimental data.

High Frequency Microwave Emission of a Tri-layer Magnetic Tunnel Junction in the Absence of External Bias-Magnetic Field

description: We perform an experimental study of DC current induced microwave emission in a magnetic tunnel junction (MTJ) consisting of three active magnetic layers. For this tri-layer structure, in addition to a conventional bilayer orthogonal MTJ containing a perpendicular free layer and an in-plane fixed layer, a second perpendicular layer has been introduced. We found that the microwave emission frequency induced by spin-transfer torque (STT) can reach as high as 6 GHz in the absence of any applied magnetic field. Moreover, microwave emission is observed for both current polarizations where a redshift is seen with increase in magnitude of current. We discuss spin-dynamics of the observed bi-directional high-frequency emission and the physical origin of the red-shift. The distinct microwave emission properties exhibited in this tri-layer MTJ structure could potentially be useful for future applications in nanoscale spintronics devices such as microwave communication and neuromorphic computing.

Exploring sub-concepts in sustainability for home economics education : two case studies
Creators: name: Kuemmerle, Nicole
Publisher: name: The University of British Columbia
Year: 2023

description: “Sustainability”, “voluntary simplicity” and “going green” are fashionably appropriate mantras for today’s world. The increasing pace of globalization and its anthropogenic impact on Earth, including the social and economic damage that contemporary lifestyles can generate, is impacting the fabric of society and consequently families. It has been proposed that home economics educators take action through a revitalized pedagogy of sustainability that encourages students to integrate and live in the modern world through emergent ideologies such as sustainability and the associated subconcepts of sustainability, collaborative consumption and upcycling. This paper explores the viability of future-proofing home economics programs through the use of alternate modes of consumption while modeling values of sustainability and sustainable practices to students. A review of the literature identifies a gap in the use of the outlined subconcepts in home economics curriculum delivery. To facilitate the future integration of collaborative consumption and upcycling in home economics education, this self-study narrative describes my personal and professional beliefs and experiences as I transcended the typical views of home economics curriculum delivery, allowing students to explore and experience some of the key concepts of sustainability, while offering them autonomy in its future use in their everyday lives.
