description: This review discusses a paradigm that has become of increasing importance in the theory of quantum phase transitions; namely, the coupling of the order-parameter fluctuations to other soft modes, and the resulting impossibility of constructing a simple Landau-Ginzburg-Wilson theory in terms of the order parameter only. The soft modes in question are manifestations of generic scale invariance, i.e., the appearance of long-range order in whole regions in the phase diagram. The concept of generic scale invariance, and its influence on critical behavior, is explained using various examples, both classical and quantum mechanical. The peculiarities of quantum phase transitions are discussed, with emphasis on the fact that they are more susceptible to the effects of generic scale invariance than their classical counterparts. Explicit examples include: the quantum ferromagnetic transition in metals, with or without quenched disorder; the metal-superconductor transition at zero temperature; and the quantum antiferromagnetic transition. Analogies with classical phase transitions in liquid crystals and classical fluids are pointed out, and a unifying conceptual framework is developed for all transitions that are influenced by generic scale invariance.

description: The increasing impact due to urban population’s food supply causes a series of negative externalities related to food production, transformation and transportation. FAO and other institutions are trying to integrate traditional models of food supply with alternative ones like Urban and Peri-Urban Agriculture (UPA). Defining the drivers that motivate the participation in different types of UPA could be useful to plan more participated and effective UPA development policies. Barcelona (Spain) hosts a number of cases representing different declinations that UPA can assume. This work aims at describing the differences in terms of motivations to enter the various typologies of Urban Agriculture (UA) in Barcelona. Data were collected through semi-structured interviews to 4 groups of users representing 3 of the most widespread models of UA initiatives in Barcelona (Allotment Gardens, Community Gardens, Pla Buits.) The results showed that participation in UA is mainly motivated by relational aspects and knowledge exchange and differences exist among the various UA models. Political reasons are mostly influencing the Community Gardeners while Pla Buits users’ mains motivations are related to socialising and Allotment gardeners are mainly motivated by environmental aspects. Differences in the participants’ demographic characteristics also emerged. Better targeted public policies contents and communication strategies for UPA development can thus be derived by the results obtained; to this end, recommendations have been provided. Further research should broaden the range of case studies and the sample size, in order to provide a more effective and comprehensive tool for tailoring UPA developing strategies to different contexts.

description: We propose a scheme for parametric amplification and phase conjugation of an atomic Bose-Einstein condensate (BEC) via stimulated dissociation of a BEC of molecular dimers consisting of bosonic atoms. This can potentially be realized via coherent Raman transitions or using a magnetic Feshbach resonance. We show that the interaction of a small incoming atomic BEC with a (stationary) molecular BEC can produce two counterpropagating atomic beams -- an amplified atomic BEC and its phase-conjugate or time-reversed replica. The two beams can possess strong quantum correlation in the relative particle number, with squeezed number-difference fluctuations.

description: Urban food systems consist of many stakeholders with different perspectives, different interests and different governance tools. This study aimed at developing potential future scenarios for the food system of Cologne by analysing the system with a Delphi approach. In our research-design, the suitability of the Delphi-method was evaluated not only as a tool for future modelling and scenario design, but also as a communication tool among the group of participants on a multistakeholder- platform. As a case study, the Food Policy Council of Cologne, Germany was used. Cologne can be seen as a forerunner among German cities in the development of a new urban food policy. Some of the successful steps to re-envisioning food as an urban system include joining the Milan Urban Food Policy Pact, the decision of the City Council to become an edible city and the establishment of a Food Policy Council. For the study it was important to capture participants’ visions of a common goal regarding the governance of the urban food system and also to identify mental ‘silos’. It was obvious that the municipality of Cologne together with the Food Policy Council made great efforts towards participatory processes to build a vision for a sustainable and regional food supply. However, many stakeholder-groups in the process still work exclusively among themselves and do not actively practice the confrontation with the viewpoints of other relevant groups. This supports the maintenance of ‘silos’ and leaves little room for face-to-face discussions. Therefore, the primary aim of this study is to explore key components of food provisioning in the future for Cologne while confronting all stakeholders (municipal administration and politicians, farmers and food activists) with the perspectives of all group members. We used a multi-stakeholder Delphi approach with 19 panellists to find out essential components of the municipal regional food provisioning system in Cologne. Unique in this Delphi study is the bringing together of municipal administration, regional urban farmers and food activists. The research is still on-going, but preliminary results show that more communication among all relevant actors, especially horizontally among different city departments, in the urban food system is needed.
Su-Schrieffer-Heeger-Hubbard model at quarter filling: effects of magnetic field and non-local interactions

description: The interplay and competition of topology and electron-electron interactions have fascinated researchers since the discovery of topological insulators. The Su-Schrieffer-Heeger-Hubbard (SSSHH) model is a prototypical model which includes both non-trivial topology and interactions. Due to its simplicity, there are several artificial quantum systems which can realize such a model to a good approximation. Here we focus on the quarter-filled case, where interactions and dimerization open a charge gap. In particular, we study the single-particle spectral function for the extended SSHH model with magnetic field and explore several parameter limits where effective model descriptions arise. In the strongly-dimerized limit, we show that the low-energy excitations of the spectral function resemble a half-filled Hubbard model with effective dimer sites and renormalized couplings. For strong magnetic field and interactions, we find physics akin to the spinless Su-Schrieffer-Heeger model at half filling, featuring a non-interacting topological phase transition. Moreover, in light of the recent realization of this model in quantum dot simulation, we provide evidence for the stability of the topological phase towards moderate non-local interactions in the experimentally expected parameter range.

Singular Kahler Potential and Heavy Top Quark in A Democratic Mass Matrix Model

description: It is pointed out that heavy top quark mass can be attributed to a singular normalization of its kinetic term, in which rescaling into canonical one yields large top Yukawa coupling. We pursue this novel possibility in a democratic mass matrix model where only the normalization of the third generation can be different from that of the other two generations. With diagonal breaking of democratic S_3 symmetry, we show that the singular normalization for the top quark is essential to reproduce observed quark masses and mixing angles. We also briefly argue other applications of this mechanism.

description: We consider a class of non-integrable 2D Ising models obtained by perturbing the nearest-neighbor model via a weak, finite range potential which preserves translation and spin-flip symmetry, and we study its critical theory in the half-plane. We prove that the leading order long-distance behavior of the correlation functions for spins on the boundary is the same as for the nearest-neighbor model, up to an analytic multiplicative renormalization constant. In particular, the scaling limit is the Pfaffian of an explicit matrix. The proof is based on an exact representation of the generating function of correlations in terms of a Grassmann integral and on a multiscale analysis thereof, generalizing previous results to include observables located on the boundary.

description: The implementation of food distribution in general and especially within urban areas requires a state-of-the-art logistics system. One decision therein is the level of centralization, with shifting optima due to emerging digitalization and peer-to-peer concepts. This study presents insights regarding the effects of innovative food logistics solutions with digitalized logistics. Findings are based on two case studies from (1) new urban distribution systems (Foodora, Lieferando and Deliveroo) and (2) Foodsharing in Germany. Results focus on the digitalized fast and short-term coordination between suppliers, transporters and customers – with interesting influences on work organization and management of workers in food distribution.

description: We study the spectral properties and eigenvector statistics of the Laplacian on highly-connected networks with random coupling strengths and a gamma distribution of rescaled degrees. The spectral density, the distribution of the local density of states, the singularity spectrum and the multifractal exponents of this model exhibit a rich behaviour as a function of the first two moments of the coupling strengths and the variance of the rescaled degrees. In the case of random coupling strengths, the spectral density diverges within the bulk of the spectrum when degree fluctuations are strong enough. The emergence of this singular behaviour marks a transition from non-ergodic delocalized states to localized eigenvectors that exhibit pronounced multifractal scaling. For constant coupling strengths, the bulk of the spectrum is characterized by a regular spectral density. In this case, the corresponding eigenvectors display localization properties reminiscent of the critical point of the Anderson localization transition on random graphs.

description: In the last two decades, the topic of sustainability has moved from the fringes of supply chain management research to the mainstream and is now an area of significant research activity, and in particular the short food supply chains (SFSCs). The growing interest in SFSCs reflects the consumer demand for quality and traceability, given the alarming health crises in food markets. The SFSCs’ have potential to increase farm value added (margin distribution), promote sustainable farming systems, diversify production and contribute to local economic development. There are many different forms of SFSC, but they share a common characteristic of reduced numbers of intermediaries between the farmer or food producer, and the consumer. From a customers' point of view, SFSCs transfer more complete information about the origin of the food and, for producers, SFSCs retain a higher share of added value. In this paper, we highlight the importance of SFSC for sustainable economic development and present the current situation in EU. The SFSCs have potential to increase farm value added (profit allocation), promote sustainable farming systems, diversify production and contribute to local economic development.

description: In this paper, we present a deep neural network (DNN) training approach called the "DeepMimic" training method. Enormous amounts of data are available nowadays for training usage. Yet, only a tiny portion of these data is manually labeled, whereas almost all of the data are unlabeled. The training approach presented utilizes, in a most simplified manner, the unlabeled data to the fullest, in order to achieve remarkable (classification) results. Our DeepMimic method uses a small portion of labeled data and a large amount of unlabeled data for the training process, as expected in a real-world scenario. It consists of a mentor model and a student model. Employing a mentor model trained on a small portion of the labeled data and then feeding it only with unlabeled data, we show how to obtain a (simplified) student model that reaches the same accuracy and loss as the mentor model, on the same test set, without using any of the original data labels in the training of the student model. Our experiments demonstrate that even on challenging classification tasks the student network architecture can be simplified significantly with a minor influence on the performance, i.e., we need not even know the original network architecture of the mentor. In addition, the time required for training the student model to reach the mentor's performance level is shorter, as a result of a simplified architecture and more available data. The proposed method highlights the disadvantages of regular supervised training and demonstrates the benefits of a less traditional training approach.

description: Food value chain businesses form alliances with horizontal and/or vertical partners to take collective action to either overcome or ameliorate chain failure, or to take advantage of new opportunities available due to innovations in products or processes. The desired outcomes from the collective action would not be possible to achieve if these businesses acted independently. While such alliances may take many forms, depending on degree of commitment and infrastructure linkages, they can often be considered to be clubs. Four such types of clubs can be identified (1) horizontal clubs comprising businesses that take collective action across a single cross-section or an aggregate of multiple cross-sections in the value chain; (2) vertical clubs, which consist of businesses that form a strategic alliance for collective action along a single value chain within a network of chains; (3) clubs that specialise in a single product or multiple products in the value chain; or (4) clubs focusing on a single input/activity or multiple inputs/activities. Thus the path to collective action chosen by clubs may vary according to existing capabilities and the scope for collaboration, particularly in relation to the potential for value-creating innovation. The result of the collective action is the provision of a chain good or service which usually leads to greater and more valuable chain coordination. By collectively identifying, funding and acting to capture positive externalities associated with innovation, businesses in many parts of a food value chain can widen opportunities to increase whole-of-chain surplus as well as increase private profits. In this paper four mini-case studies are presented which demonstrate the breadth of past collective actions that have been undertaken by a substantial proportion of businesses in food value chains, two in Europe and two in Australia. These are (1) the Euro Pool System, (2) Global Standards certification in Europe and globally, (3) Meat Standards Australia, and (4) the OBE Beef organic producer alliance in Australia. Each case study yields insights into the rationale of how businesses in different food value chains in different countries have acted as a club to use their joint resources to internalise positive innovation and coordination externalities that would not have been possible to achieve were these businesses to act independently.
Possible Fano effect and suppression of Andreev reflection in La$_3$Ni$_2$O$_7$

description: The recently-discovered high-temperature superconductor La$_3$Ni$_2$O$_7$ under high pressure has stimulated intensive debates. Key controversies concern interlayer versus intralayer pairing scenarios and if the hybridization plays a key role in establishing the superconductivity. But experimental clarification is difficult due to the limitation of employing state-of-the-art techniques under high pressure. Here we propose that quasiparticle tunneling and Andreev reflection may provide a feasible way to distinguish different pairing scenarios. We predict that an asymmetric Fano line shape may be induced by the hybridization between the $d_{x^2-y^2}$ metallic bands and the strongly renormalized flat $d_{z^2}$ quasiparticle bands. In the superconducting state, we show that the Andreev reflection should be greatly suppressed for interlayer pairing superconductivity with a small interlayer hopping. We propose future experiments to examine these predictions and help clarify the fundamental physics of superconducting La$_3$Ni$_2$O$_7$ and other multilayer nickelate superconductors.

description: As requested by UBC SEEDS (Social Ecological Economic Development Studies), Urban Tech Consultants Ltd. is pleased to present the final detailed design for UBC's East Mall road layout between Agronomy and West 16th Ave. The design aims to promote sustainable transportation and safe use for all traffic modes, implement green infrastructure and efficient stormwater drainage systems, accommodate high drop-off and pick-up activities, and incorporate the future Stadium Neighborhood development to a most cost-effective solution. The detailed design utilizes stop control intersections on Agronomy Road, Eagles Drive, Stadium Neighborhood intersections, and a roundabout on W 16th Avenue. Thunderbird Boulevard intersection will remain as an actuated signalized intersection but with efficient reconfigured sequencing and timing. The new roadway design consists of 2 travel lanes separated by a median boulevard with dedicated bike lanes and sidewalks separated by green space with a weather-protected shelter for a pedestrian crossing at Agronomy Road. Detailed plan and cross-sectional view of the roadway, construction specifications, traffic analysis data, schedule and cost estimations are included in the appendix. The updated total life cycle project cost is $ 4,297,674.43, with $1,874,074.43 allocated for the initial consulting and construction costs, $2,503,500.00 for the operation and maintenance cost for 50 years, and $79,990.00 project decommissioning salvage value. The project's expected start date and completion date are on May 1, 2021, and September 30, 2021, respectively. A Gantt chart consisting of time and duration for both project construction and completion tasks is also provided.

description: We consider open superstring partition function Z on the disc in time-dependent tachyon background T= f(x_i) e^{m x_0} where the profile function f depends on spatial coordinates. We compute Z to second order in derivatives of f and compare the result with some previously suggested effective actions depending only on the first derivatives of the tachyon field. We also compute the target-space stress-energy tensor in this background and demonstrate its conservation in the ``on-shell'' case of the linear profile f= f_0 + q_i x_i corresponding to a marginal perturbation. We comment on the role of the rolling tachyon with linear spatial profile in the decay of an unstable D-brane.

description: Certain members of a population consciously and deliberately decide to take joint action to provide particular types of goods or services that are at least partly excludable and at least partly congestible because it is too costly to provide such goods individually. These goods are called club goods or collective goods. We first define some key concepts in club theory and public choice. This includes the prospects for determining the optimal level of membership of a club, how to determine the optimal level and range of provision of services by a club, and consideration of the dynamics of club membership. Then we examine the ways in which club theory can help provide an alternative approach to recognising and overcoming market failure in agricultural and food value chains. We note that useful insights can be gained by considering value chains as ‘latent clubs’. That is, they are systems that exist but which are either inactive or have not been fully developed, but which have the potential for improvement through collective action. If value chain members do exploit an opportunity to reap the rewards of collective action, then forming a club that comprises the whole chain or a subset of chain members offers an efficient organisation design to do so. We find that all of the calculus that has been identified for clubs can be applied to agricultural and food value chains. However, there are two particular issues that require further consideration. One is the nature of risk in agricultural value chains, and how it is related to member preferences, and the other is the form of collective action to be taken by agricultural value chains in the future.

description: In the framework of a Fermi liquid theory it is considered the possibility of appearance of spin polarized states in strongly asymmetric nuclear matter with Skyrme effective interaction. The zero temperature dependence of neutron and proton spin polarization parameters as functions of density is found for SLy4, SLy5 effective forces. It is shown that at some critical density it will be formed the state with the oppositely directed spins of neutrons and protons, while the state with the same direction of spins does not appear. In comparison with neutron matter, even small admixture of protons strongly decreases the threshold density of spin instability. It is clarified that protons become totally polarized within very narrow density domain while in the density profile of neutron spin polarization parameter their appear long tails near the transition density.

description: We describe a cavity-enhanced spontaneous parametric down-conversion (CE-SPDC) source for narrowband photon pairs with filters such that over 97% of the correlated photons are in a single mode of 4.3(4) MHz bandwidth. Type-II phase matching, a tuneable-birefringence resonator, MHz-resolution pump tuning, and tuneable Fabry-Perot filters are used to achieve independent signal and idler tuning. We map the CE-SPDC spectrum using difference frequency generation to precisely locate the emission clusters, and demonstrate CE-SPDC driven atomic spectroscopy. The generated photon pairs efficiently interact with neutral rubidium, a well-developed system for quantum networking and quantum simulation. The techniques are readily extensible to other material systems.

description: We present a detailed analysis of a 3.5 s long burst from SGR1900+14 which occurred on 2001 July 2. The 2-150 keV time-integrated energy spectrum is well described by the sum of two blackbodies whose temperatures are approximately 4.3 and 9.8 keV. The time-resolved energy spectra are similarly well fit by the sum of two blackbodies. The higher temperature blackbody evolves with time in a manner consistent with a shrinking emitting surface. The interpretation of these results in the context of the magnetar model suggests that the two blackbody fit is an approximation of an absorbed, multi-temperature spectrum expected on theoretical grounds rather than a physical description of the emission. If this is indeed the case, our data provide further evidence for a strong magnetic field, and indicate that the entire neutron was radiating during most of the burst duration.

POIROT: Aligning Attack Behavior with Kernel Audit Records for Cyber Threat Hunting

description: Cyber threat intelligence (CTI) is being used to search for indicators of attacks that might have compromised an enterprise network for a long time without being discovered. To have a more effective analysis, CTI open standards have incorporated descriptive relationships showing how the indicators or observables are related to each other. However, these relationships are either completely overlooked in information gathering or not used for threat hunting. In this paper, we propose a system, called POIROT, which uses these correlations to uncover the steps of a successful attack campaign. We use kernel audits as a reliable source that covers all causal relations and information flows among system entities and model threat hunting as an inexact graph pattern matching problem. Our technical approach is based on a novel similarity metric which assesses an alignment between a query graph constructed out of CTI correlations and a provenance graph constructed out of kernel audit log records. We evaluate POIROT on publicly released real-world incident reports as well as reports of an adversarial engagement designed by DARPA, including ten distinct attack campaigns against different OS platforms such as Linux, FreeBSD, and Windows. Our evaluation results show that POIROT is capable of searching inside graphs containing millions of nodes and pinpoint the attacks in a few minutes, and the results serve to illustrate that CTI correlations could be used as robust and reliable artifacts for threat hunting.

description: Cracticus torquatus colletti Mathews
Cracticus torquatus colletti Mathews, 1912b: 46 (Northern Territory).
Now Cracticus argenteus colletti Mathews, 1912. See Amadon, 1951: 7–8; 1962b: 166; Storr, 1977: 101–102; Schodde and Mason, 1999: 538–541; Dickinson, 2003: 463; and Russell and Rowley, 2009: 337–338.
HOLOTYPE: AMNH 673539, adult male, collected on the Mary River, Northern Territory, Australia, on 15 May 1895, by Knut Dahl (no. 1203). From the Mathews Collection (no. 10162) via the Rothschild Collection.
COMMENTS: In the original description, Mathews gave his catalog number of the holotype and noted the range as Northern Territory. Mathews (1912b: 25) had just received specimens from Professor R. Collett, ZMO, including those collected by Dahl, and the holotype was apparently the only specimen he had. Three specimens in AMNH collected by J.T.Tunney on the South Alligator River in 1903 were never in the Mathews Collection.
Apparently, this holotype had not been recognized prior to Amadon (1962b). Even though it bears a Mathews type label in addition to the original label and a Rothschild Collection label printed ‘‘Ex. Coll. G.M. Mathews,’’ it has no Rothschild type label; the AMNH type label is filled in by Amadon.
Amadon (1962b: 166) considered argenteus and torquatus to be conspecific and, accepting Port Essington as the type locality of torquatus, synonymized colletti with it and recognized four subspecies. Schodde and Mason (1999: 540–541) explained their reasons for considering argenteus specifically distinct from C. torquatus and noted that they accepted Hanover Bay in the Kimberley Division as the type locality of argenteus, leaving colletti as the available name for Northern Territory birds. This was followed by Dickinson (2003: 463). Russell and Rowley (2009: 337) accepted five subspecies in a single species, C. torquatus, including C. t. colletti, but noted that if Port Essington is accepted as the type locality of argenteus, then colletti is a synonym and the name latens Ford, 1979, is available for the Western Australian form (type in WAM).
Dahl (1927: 196–218) and his party were camping at the headwaters of the Mary River in May 1895, in the vicinity of Fountainhead, 13.28S, 131.29E (USBGN, 1957).
