description: We consider the most general teleparallel theory of gravity whose action is a linear combination of the five scalar invariants which are quadratic in the torsion tensor. Since two of these invariants possess odd parity, they naturally allow for a coupling to pseudo-scalar fields, thus yielding a Lagrangian which is even under parity transformations. In analogy to similar fields in gauge theories, we call these pseudo-scalar fields \emph{teleparallel axions}. For the most general coupling of a single axion field, we derive the cosmological field equations. We find that for a family of cosmologically symmetric teleparallel geometries, which possess non-vanishing axial torsion, the axion coupling contributes to the cosmological dynamics in the early universe. Most remarkably, this contribution is also present when the axion is coupled to the teleparallel equivalent of general relativity, hence allowing for a canonical coupling of a pseudo-scalar to general relativity. For this case we schematically present the influence of the axion coupling on the fixed points in the cosmological dynamics understood as dynamical system. Finally, we display possible generalizations and similar extensions in other geometric frameworks to model gravity.

description: This paper investigates a novel active-sensing-based obstacle avoidance paradigm for flying robots in dynamic environments. Instead of fusing multiple sensors to enlarge the field of view (FOV), we introduce an alternative approach that utilizes a stereo camera with an independent rotational DOF to sense the obstacles actively. In particular, the sensing direction is planned heuristically by multiple objectives, including tracking dynamic obstacles, observing the heading direction, and exploring the previously unseen area. With the sensing result, a flight path is then planned based on real-time sampling and uncertainty-aware collision checking in the state space, which constitutes an active sense and avoid (ASAA) system. Experiments in both simulation and the real world demonstrate that this system can well cope with dynamic obstacles and abrupt goal direction changes. Since only one stereo camera is utilized, this system provides a low-cost and effective approach to overcome the FOV limitation in visual navigation.

description: We study Rényi entropies for geometries with Lifshitz scaling and hyperscaling violation. We calculate them for specific values of the Lifshitz parameter, and analyze the dual spectrum of the ground state. In the large $d-θ$ limit they show that the ground state is unique in specific parameter ranges. We also calculate the Rényi entropies perturbatively around $n=1$, and derive constraints using the Rényi entropy inequalities, which correspond to the thermodynamic stability of the black holes.

description: Our research reveals that POLM plays an important role in ovarian cancer development, especially the mutation G312R. We uncover the POLM G312R mutation as a driver of genomic instability in ovarian cancer via aberrant ribonucleotide incorporation. We reveal POLMG312R upregulates COL11A1 and activates NF-κB signaling, contributing to tumor progression and chemoresistance. This study identifies the POLM G312R-COL11A1-NF-κB axis as a novel oncogenic pathway.

description: In eukaryote nucleosome, DNA wraps around a histone octamer in a left-handed way. We study the process of chirality formation of nucleosome with Brownian dynamics simulation. We model the histone octamer with a quantitatively adjustable chirality: left-handed, right-handed or non-chiral, and simulate the dynamical wrapping process of a DNA molecule on it. We find that the chirality of a nucleosome formed is strongly dependent on that of the histone octamer, and different chiralities of the histone octamer induce its different rotation directions in the wrapping process of DNA. In addition, a very weak chirality of the histone octamer is quite enough for sustaining the correct chirality of the nucleosome formed. We also show that the chirality of a nucleosome may be broken at elevated temperature.

Magnetic field-induced "mirage" gap in an Ising superconductor

description: Superconductivity is commonly destroyed by a magnetic field due to orbital or Zeeman-induced pair breaking. Surprisingly, the spin-valley locking in a two-dimensional superconductor with spin-orbit interaction makes the superconducting state resilient to large magnetic fields. We investigate the spectral properties of such an Ising superconductor in a magnetic field taking into account disorder. The interplay of the in-plane magnetic field and the Ising spin-orbit coupling leads to noncollinear effective fields. We find that the emerging singlet and triplet pairing correlations manifest themselves in the occurrence of "mirage" gaps: at (high) energies of the order of the spin-orbit coupling strength, a gap-like structure in the spectrum emerges that mirrors the main superconducting gap. We show that these mirage gaps are signatures of the equal-spin triplet finite-energy pairing correlations and due to their odd parity are sensitive to intervalley scattering.

The ESR amplitude and its temperature dependence suggest that the signal originates from the effective magnetic field caused by the spin orbit-interaction and a modulation of the electron wavevector caused by the microwave electric field. This contrasts markedly to conventional ESR that detects through the microwave magnetic field.

Subjects: food; P.D.O. certification; willingness to pay; regional differences; conjoint analysis

description: The purpose of this paper is to investigate consumer preferences and estimate their willingness to pay (WTP) for P.D.O. (Protected Designation of Origin) certification. The original contribution of this analysis is the evidence provided on regional differences among consumers in their evaluations. We interpret this result as the higher level of information available to consumers that live in the production region of the food product in question, thus giving less value to P.D.O. certification. The product that this study focuses on is Italian P.D.O. Fontina cheese. In order to conduct the study, we collected original data that we analyze through the conjoint analysis technique.

Year: 2014
Subjects: Animal welfare label; certification systems; process quality of food products

description: The process quality of food products is currently the subject of increased attention. In the area of meat production, public discussion has centered on perceived low standards of animal welfare. Besides an increase in legislative regulations, improved animal welfare standards are most frequently achieved through the establishment of socalled animal welfare labels. So far these labeling concepts have not been substantially evaluated in terms of how well they carry out their goal of improving process quality in agricultural animal husbandry. This paper will use a recognized list of criteria to evaluate selected animal welfare labels. Results show that competing labels vary strongly regarding the improvement of process quality. This has far‐reaching effects not only for consumers and
other label users, but also for companies that want to enter the animal welfare segment of the meat market.

Can Differentiated Production Planning and Control enable both Responsiveness and Efficiency in Food Production?

Publisher: name: CentMA
Year: 2014
Subjects: food production; planning and control; responsiveness; case study

description: This paper addresses the complex production planning and control (PPC) challenges in food supply chains. The study illustrates how food producers' traditional make‐to‐stock (MTS) approach is not well suited to meet the trends of increasing product variety, higher demand uncertainty, increasing sales of fresh food products and more demanding customers. The paper proposes a framework for differentiated PPC that combines MTS with make‐to‐order (MTO).
The framework matches products with the most appropriate PPC approaches and buffering techniques depending on market and product characteristics. The core idea is to achieve more volume flexibility in the production system by exploiting favourable product and market characteristics (high demand predictability, long customer order lead
time allowances and low product perishability). A case study is used to demonstrate how the framework can enable food producers to achieve efficiency in production, inventory and PPC processes – and simultaneously be responsive to market requirements.

Trophic structure of the eastern Chukchi Sea : an updated mass balance food web model

description: This is a 2010s update of the previous 1990s Ecopath trophic mass balance model of the eastern Chukchi Sea. In the time since the original 1990s model was developed, a number of datasets have been produced and several reports and journal articles published documenting the findings of recent field studies in the eastern Chukchi Sea, including the completion of the BOEM-funded Arctic Ecosystem Integrated Survey (Arctic Eis). In this report we use published and unpublished datasets from many of these recent studies to update several input parameters from the preliminary 1990s Ecopath model of eastern Chukchi Sea, so it is more representative of the current (2010s) state of the eastern Chukchi Sea food web. Overall, 93 input parameters were updated and the data quality was improved for 34 parameters. A total of 9 new functional groups were added, 6 for seabirds and 3 for fish. Here we document all model parameters that we were able to update with improved information, including estimates of biomass, production, consumption, and diet composition. Changes in the included species, the species composition of functional groups, and their related parameters resulted in higher biomass for marine mammals, seabirds, fish and zooplankton, and decreased biomass for benthic invertebrates, jellies, microbes, and phytoplankton. Additionally, we calculate several ecosystem-level metrics for both models and compare the results between the original model and our updated model. In both models, benthic invertebrates represent the dominant portion of total ecosystem biomass, and energy flow is dominated by benthic resources. Total energy flow, total production, total biomass, and net primary production decreased from the preliminary model to the updated model. A key result common to both the preliminary model and the updated model is that trawl-survey-derived estimates of demersal fish biomass were insufficient to balance the model. Fish biomass needed to be several times greater to meet the modeled trophic demand from predators. Changes in the ecosystem metrics are the reflection of the updated and improved (higher quality) model inputs, and do not necessarily reflect any change in ecosystem state between the two model time periods. Given the number of updated parameters and improved data quality in the updated model (2010s), we recommend using the updated model over the preliminary model (1990s) for future modeling studies and as a baseline of this system’s food web.

description: The dynamics of a quantum system following a sudden, highly non-adiabatic change of its control parameter (quantum quench) is studied with quasiclassical techniques. Recent works have shown, using exact quantum mechanical approach, that equilibration after quantum quench exhibits specific features in the presence of excited-state quantum phase transitions. In this paper, we demonstrate that these features can be understood from the classical evolution of the Wigner function in phase space.

description: The horticulture and propagation materials sector has been designated as one of the so‐called top sectors in which the Netherlands excels globally and that are a government priority. The top sector approach for further innovation is based on public‐private partnerships (PPPs) in which businesses, knowledge institutes and the (national) government are working closely together towards a common vision and action plans (the 'golden triangle'). This paper introduces the Digital Greenport Holland (Dutch: Tuinbouw Digitaal) and its research and innovation
programme ‘a Smarter Greenport’. Digital Greenport Holland is the PPP of the horticultural top sector that focuses on digital information management. The business involvement consists of the collaboration between three active
industry associations for chain information, i.e. Frug I Com (fruit and vegetables), Floricode (flowers and plants) and EDIbulb (flower bulbs). The activities focus on four main themes: E‐standards, E‐information‐integration, Ebusiness‐to‐government and E‐competence. The programme ‘a Smarter Greenport’ has currently conducted eight projects on these themes.

description: We report a deterministic 2D material (2DM) transfer method to assemble any-stacking-order heterostructures incorporating suspended ultra-thin 2D materials, such as single-layer graphene (SLG) and bilayer graphene (BLG). The transfer procedure relies on a single-step preparation nitrocellulose micro-stamp, which combines both outstanding adhesion and softness. It permits the dry pick-up of naked 2D crystals (graphene, MoS$_2$, and hBN) directly from a SiO$_2$ substrate, and to precisely transfer them on substrates or trenches. Optical and Raman data show that no significant defect is introduced upon transfer, even in suspended SLG and BLG. The areas transferred range up $\sim$ 1000 $μ$m$^2$ on substrate. High-yield transfer of suspended ultra-thin 2DM does not require critical point drying for areas up to 15 $μ$m$^2$ or suspension heights down to 160 nm. To demonstrate the method's capabilities, we assembled on-substrate and suspended optical cavities tuning BLG's Raman scattering intensity by factors of 19 and 4, respectively. This resilient and rapid 2DM transfer procedure will accelerate the fabrication of many heterostructures and permit versatile suspension of 2DMs for research in twistronics, straintronics, and nano-opto-electro-mechanical systems (NOEMS).

description: We have studied the ground state structure of quantum strips within the local spin-density approximation, for a range of electronic densities between $\sim$ 5$\times10^4$ and 2$\times10^6$ cm$^{-1}$ and several strengths of the lateral confining potential. The results have been used to address the conductance $G$ of quantum strips. At low density, when only one subband is occupied, the system is fully polarized and $G$ takes a value which is close to 0.7(2e$^2/h$), decreasing with increasing electron density in agreement with experiments. At higher densities the system becomes paramagnetic and $G$ takes a value near (2e$^2/h$), showing a similar decreasing behaviour with increasing electron density. In both cases, the physical parameter that determines the value of the conductance is the ratio $K/K_0$ of the compressibility of the system over the free one.

The biology of infection by loma salmonae (microsporidia)
Creators: name: Shaw, Ross Winning
Publisher: name: University of British Columbia
Year: 2009

description: Loma salmonae is an important gill pathogen of Pacific salmon Oncorhynchus spp. in the Pacific Northwest. Epizootics of the parasite have caused considerable economic loss in Pacific salmon farming in British Columbia. A study was undertaken on the basic biology of L. salmonae since very little information exists to aid fish-farmers and scientists. Loma salmonae transmission was examined by challenging fish by per os (oral), injection, and cohabitation with infected fish. Loma salmonae is transmissible by experimental (e.g. intraperitoneal, intramuscular injection) and natural (e.g. peros, cohabitation of naive and infected fish) exposure routes. Autoinfection of hosts is possible as demonstrated by intravascular injections of spores producing infection. The route of infection in salmon was examined using histological techniques. Sporoplasms from extruded spores were detected in epithelial cells of the alimentary canal. The parasite may move through these cells and enter the blood stream eventually reaching the gills. Purified spores were held under various laboratory conditions to examine viability. Spores were still infective after 95 d at 4 °C in fresh or sea water. Spores were killed when frozen or exposed to 100 or 200 ppm iodophor, although some spores survived the latter treatment. Host specificity of L. salmonae was examined by per os exposure of salmonids and nonsalmonds. All Oncorhynchus spp. tested were susceptible, but Atlantic salmon and Arctic char were resistant. All nonsalmonids tested were resistant. A Northern Stream strain of Chinook showed higher susceptibility to the parasite when compared to a Southern Coastal or hybrid strains. Macrophage phagocytic ability was investigated as a possible mechanism to explain differences between strains and susceptible or resistant salmonids. No differences were found between strains but Atlantic salmon macrophages have a higher phagocytic response to L. salmonae spores than Chinook. The possibility of nonsalmonid reservoirs for L. salmonae was examined by collecting different life stages of salmonids and nonsalmonids near Vancouver Island. Loma salmonae was present throughout the life cycle of wild salmonids and a new Loma sp. is described from Cymatogaster aggregata using morphology, transmission studies, and rDNA sequencing.

description: Based on an analysis of the supply chain of four producers of local specialty foods, we explore how planning and control principles can be applied to align supply chain capabilities and market requirements. It has been shown that local food struggles with market access, and that the supply chain is one of the obstacles preventing local food producers from gaining a solid market position. We identify a number of features of the local food chain, analyse the obstacles and develop generic designs and control principles for local food producers.

Subjects: Crop Production/Industries

description: Prices received by Australian wheat farmers have increasingly depended on grain quality, especially protein concentration. This concentration depends on various agronomic and physical factors including weed competition. In this paper a model of weed management in the presence of grain quality premiums is presented. Two types of quality premium are examined: a continuout linear payment schedule and a discontinuous "stepped" schedule with substantial premiums for quality levels above a critical level. The model is applied to an analysis of the impact of protein premiums on optimal management strategies for a particular weed in Western Australia. It is found that the impact of protein premiums on optimal weed management is likely to be very small indeed, even if premiums were substantially increased above current levels.

description: Promoting environmentally friendly farming products is crucial to meeting consumer demand. Although governments implement policy measures to improve the environmental performance of the agriculture sector, their
impacts are difficult to assess. This study analyses the performance of agri‐environmental policies in Japan, by using the OECD’s policy impact model and reference level framework. In particular, it identifies the environmental impacts of three simulated agri‐environmental policies based on farms’ characteristics. The results suggest that a policy mix of regulation and an incentive payment would reduce environmental impacts, suggesting that targeted approaches could improve the cost‐effectiveness of agri‐environmental policies.

description: The idea of a new world order suggests political and economic changes that would improve the lot of all the people in the world. Such a new world order would address all causes of poverty and inequality both within nations and between nations. Desirable changes would modify present competitive patterns of organisation and substitute more cooperative systems and processes. Writers in this area focus particularly on how to change the current state of the world in order to achieve a transition to a more desirable new world order. From an economic point of view, this transition could be interpreted as an attempt to frame new political, economic and social institutions and rules of conduct that would enable the equity goals of the proposers to be achieved.

description: Stars of all evolutionary phases have been found to have excess infrared emission due to the presence of circumstellar material. To identify such stars, we have positionally correlated the infrared MSX point source catalogue and the Tycho 2 optical catalogue. A near/mid infrared colour criteria has been developed to select infrared excess stars. The search yielded 1938 excess stars, over half (979) have never previously been detected by IRAS. The excess stars were found to be young objects such as Herbig Ae/Be and Be stars, and evolved objects such as OH/IR and carbon stars. A number of B type excess stars were also discovered whose infrared colours could not be readily explained by known catalogued objects.

description: During the soccer game, coaches have to make strategic decisions on player substitutions. Player substitutions made at the right time and with the right player can have a significant impact on winning the competition. The aim of this study is to investigate the effects of player substitutions in Turkish Super League competitions on match winning performance. The sample of the present study was composed of 100 matches randomly selected from the Turkish Professional Soccer League (Super League) during the 2020-2021 season. A total of 766 player substitutions made by the home and away teams in these competitions were analyzed according to the determined parameters. All the data obtained were given and interpreted as frequency and percentage values. As a result of the analyzes carried out, it was determined that the first player substitutions occurred mostly in the half-time and between 46-60 minutes of the competitions. It was found that the second player substitutions occurred mostly between the 61-75 minutes of the games. It has been observed that the third, fourth and fifth substitutions are mostly made between the 76-90 minutes of the matches. As a result, the fact that the coaches make more substitutions, especially between the 61-90 minutes of the matches, can be explained as the result of a strategy they apply to win the match by interfering with the game. In addition, coaches' substitutions time strategies can have an impact on the game tactics applied during the competition and final outcome in the match.

description: By arithmeticity and superrigidity, a commensurability class of lattices in a higher rank Lie group is defined by a unique algebraic group over a unique number subfield of $\mathbb{R}$ or $\mathbb{C}$. We prove an adelic version of superrigidity which implies that two such commensurability classes define the same profinite commensurability class if and only if the algebraic groups are adelically isomorphic. We discuss noteworthy consequences on profinite rigidity questions.

description: National parks as natural areas preserved from the more disruptive forms of economic activity provide a multitude of benefits to humankind, and these may be classified as either on-site use benefits or off-site benefits. This paper reports an applied case which is concerned with the measurement of the value of the recreational use benefits for one such national park. Whilst the national park is under no immediate threat, having an indication of the economic value of recreational opportunities within the park can aid future planning and decision-making. The emphasis in this study was to use and test TCM for rapid valuation appraisal. Demand curves for both camping and day visits are estimated. and consumer surplus calculated. A value of $40m. is estimated as the net present value of the recreational use alone in 1993-94 values at 6 per cent real rate of interest in perpetuity.

description: The Water Resources Commission of New South Wales has calculated the capital and operating costs of diverting the amount of water which would be available in the driest year from the major coastal rivers to the inland streams of New South Wales. A preliminary benefit cost analysis of the least cost diversion to each inland stream, using a discount rate of 3 per cent, indicates that at present prices and yields none of the projects would have a benefit cost ratio of greater than 0.93, even if all of the diverted water were utilised immediately by farmers for the most profitable activity. If a discount rate of 7 per cent is used, this benefit cost ratio would decline to 0.52. If water is taken up at the same rate as it was after Copeton Dam was completed on the Gwydir River and utilized for the same purposes as it is on the inland rivers at present, no scheme would have a benefit cost ratio of more than 0.31, and most would have a benefit cost ratio of less than 0.22, using a 7 per cent discount rate.

Are radio galaxies and quiescent galaxies different? Results from the analysis of HST brightness profiles

description: We present a study of the optical brightness profiles of early type galaxies, using a number of samples of radio galaxies and optically selected elliptical galaxies. For the radio galaxy samples--B2 of Fanaroff-Riley type I and 3C of Fanaroff-Riley type II-- we determined a number of parameters that describe a "Nuker-law" profile, which were compared with those already known for the optically selected objects. We find that radio active galaxies are always of the "core" type (i.e. an inner Nuker law slope gamma < 0.3). However, there are core-type galaxies which harbor no significant radio source and which are indistinguishable from the radio active galaxies. We do not find any radio detected galaxy with a power law profile (gamma > 0.5). This difference is not due to any effect with absolute magnitude, since in a region of overlap in magnitude the dichotomy between radio active and radio quiescent galaxies remains. We speculate that core-type objects represent the galaxies that have been, are, or may become, radio active at some stage in their lives; active and non-active core-type galaxies are therefore identical in all respects except their eventual radio-activity: on HST scales we do not find any relationship between boxiness and radio-activity. There is a fundamental plane, defined by the parameters of the core (break radius r_b and break brightness mu_b), which is seen in the strong correlation between r_b and mu_b. The break radius is also linearly proportional to the optical Luminosity in the $I$ band. Moreover, for the few galaxies with an independently measured black hole mass, the break radius turns out to be tightly correlated with M_{BH}. The black hole mass correlates even better with the combination of fundamental plane parameters r_b and mu_b, which represents the central velocity dispersion.

Effect of Crystal-Field Splitting and Inter-Band Hybridization on the Metal-Insulator Transitions of Strongly Correlated Systems

description: We investigate a quarter-filled two-band Hubbard model involving a crystal-field splitting, which lifts the orbital degeneracy as well as an inter-orbital hopping (inter-band hybridization). Both terms are relevant to the realistic description of correlated materials such as transition-metal oxides. The nature of the Mott metal-insulator transition is clarified and is found to depend on the magnitude of the crystal-field splitting. At large values of the splitting, a transition from a two-band to a one-band metal is first found as the on-site repulsion is increased and is followed by a Mott transition for the remaining band, which follows the single-band (Brinkman-Rice) scenario well documented previously within dynamical mean-field theory. At small values of the crystal-field splitting, a direct transition from a two-band metal to a Mott insulator with partial orbital polarization is found, which takes place simultaneously for both orbitals. This transition is characterized by a vanishing of the quasiparticle weight for the majority orbital but has a first-order character for the minority orbital. It is pointed out that finite-temperature effects may easily turn the metallic regime into a bad metal close to the orbital polarization transition in the metallic phase.

On the massive two-loop corrections to Bhabha scattering

description: We overview the general status of higher order corrections to Bhabha scattering and review recent progress in the determination of the two-loop virtual corrections. Quite recently, they were derived from combining a massless calculation and contributions with electron sub-loops. For a massive calculation, the self-energy and vertex master integrals are known, while most of the two-loop boxes are not. We demonstrate with an example that a study of systems of differential equations, combined with Mellin-Barnes representations for single masters, might open a way for their systematic calculation.

$X_J(2900)$ states in a hot hadronic medium

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this work we investigate the hadronic effects on the $X_{J=0,1} (2900)$ states in heavy-ion collisions. We make use of Effective Lagrangians to estimate the cross sections and their thermal averages of the processes $X_J π\to \bar{D}^{*} K , K^{*} \bar{D} $, as well as those of the corresponding inverse processes, considering also the possibility of different isospin assignments ($I=0,1$). We complete the analysis by solving the rate equation to follow the time evolution of the $X_J (2900)$ multiplicities and determine how they are affected by the considered reactions during the expansion of the hadronic matter. We also perform a comparison of the $X_J (2900)$ abundances considering them as hadronic molecular states ($J=0$ as a $S$-wave and $J=1$ as a $P$-wave) and tetraquark states at kinetic freeze-out.

description: An assessment is presented of the costs and benefits of a scheme in the New England region of New South Wales for the control of footrot in sheep. An ex post evaluation is presented of the operation of the scheme since its inception in 1960 to the present, and also an ex ante appraisal is made of the proposed continuation of the scheme in the future. Data were collected from the implementing agencies and from samples of sheep farmers in the target area and in another area where the disease is endemic. Some coefficients not otherwise available were estimated by a panel of experts by use of a Delphi procedure. Net benefits from the scheme were estimated directly as producers' surpluses less administrative costs, assuming no effects on output prices. Relatively large positive net present values and benefit-cost ratios were obtained for both the past and future operation of the scheme. The findings are shown to be robust under sensitivity analysis. It is argued that any reduction in the price of wool caused by the supply shift would not offset the advantages to producers in the region of the scheme. Producers in other regions, however, would suffer losses from a price fall, although the net benefit to Australia as a whole is likely to be positive.
