description: Sustainable procurement requires organizations to align their purchasing behavior with regard to broader goals linked to resource efficiency, climate change, social responsibility and other sustainability criteria. The level of sustainability in Information and Communication Technology (ICT) hardware procurement is analyzed for two reasons: First, ICT hardware belongs to the six key product groups in sustainable procurement. Second, ICT in general is expected to be an important enabler for low-carbon economies, providing solutions to reduce Green-House Gas (GHG) emissions. While the advantages of sustainable procurement are obvious, certain barriers hinder the adoption in day-to-day procurement. This case study on ICT hardware discusses the three important barriers "lack of clear definitions per product group", "missing market intelligence about sustainable products" and "inflexible procedures and attitudes as barriers for innovative approaches" based on an in-depth analysis of sustainable procurement of ICT hardware by the public sector in Switzerland. To this end, tender data published on the national procurement platform simap.ch is screened for sustainability criteria using the Common Procurement Vocabulary (CPV) nomenclature to identify relevant ICT projects. The results reveal to which extent such criteria as well as their determinants are currently included in public tenders. Using two different approaches, only a small number of tenders were found containing sustainability criteria of a wide range from basic to comprehensive. The overall performance of Swiss public procurement is benchmarked by comparing the identified sustainability criteria with available criteria from international key actors in sustainable procurement. Thus, this analysis provides novel insights on how public agencies today take sustainability into account when procuring ICT hardware.

description: In this paper, the use of cost-effective, custom home experiment kits for remote teaching of first-semester introductory physics labs is described. The kit experiments were designed to match the existing onsite lab experiment learning goals and the general laboratory course learning goals in remote teaching. Additionally, a revised group project approach optimized for remote use and that leverages the kits was developed and employed. Student survey results at the end of the Summer 2020 semester indicate that the critical learning goals were met, student satisfaction with the remote lab was maintained, and successful collaboration via video-conferencing breakout rooms was achieved.
Ferromagnetic instabilities in neutron matter at finite temperature with the Skyrme interaction

description: The properties of spin polarized neutron matter are studied both at zero and finite temperature using Skyrme-type interactions. It is shown that the critical density at which ferromagnetism takes place decreases with temperature. This unexpected behaviour is associated to an anomalous behaviour of the entropy which becomes larger for the polarized phase than for the unpolarized one above a certain critical density. This fact is a consequence of the dependence of the entropy on the effective mass of the neutrons with different third spin component and a new constraint on the parameters of the effective Skyrme force is derived in order to avoid such a behaviour.

description: Hypothesis: Sphingomyelin (SPM), a crucial phospholipid in the myelin sheath, is vital in insulating nerve fibers. We hypothesize that iron ions selectively bind to the phosphatidylcholine (PC) template within the SPM membrane under near-physiological conditions, disrupting membrane organization. These interactions could potentially contribute to the degradation of the myelin sheath, thereby playing a role in the development of neurodegenerative diseases. Experiments: We utilized synchrotron-based X-ray spectroscopy and diffraction techniques to study the interaction of iron ions with a bovine spinal cord SPM monolayer (ML) at the liquid-vapor interface under physiological conditions. The SPM ML serves as a model system, representing localized patches of lipids within a more complex membrane structure. The experiments assessed iron binding to the SPM membrane both in the presence of salts and with additional evaluation of the effects of various ion species on membrane behavior. Grazing incidence X-ray diffraction was employed to analyze the impact of iron binding on the structural integrity of the SPM membrane. Findings: Our results demonstrate that iron ions in dilute solution selectively bind to the PC template of the SPM membrane exclusively at near-physiological salt concentrations (e.g., NaCl, KCl, KI, or CaCl2) and are pH-dependent. In-significant binding was detected without these salts or at near-neutral pH with salts. The surface adsorption of iron ions is correlated with salt concentration, reaching saturation at physiological levels. In contrast, multivalent ions such as La$^{3+}$ and Ca2+ do not bind to SPM under similar conditions. Notably, iron binding to the SPM membrane disrupts its in-plane organization, suggesting that these interactions may compromise membrane integrity and contribute to myelin sheath damage associated with neurological disorders.

description: There is an increasing consumers' concern for food safety and quality and, at the same time, there has been a significant market increment in differentiated or high value products consumption, including organic products. The lack of empirical research in Argentina regarding consumers' awareness of food safety brought our attention. Therefore, the objective of this paper is to analyse consumers' perceptions about the risk and quality attributes of food consumption; and to evaluate the incidence of these factors when buying organic products in Argentina. The Lancaster model (1966) provided the theoretical basis for the use of products attributes and characteristics to analyse the incidence of these attributes in consumers' choices. The data used in this study derives from a food consumption survey on organic and non-organic consumers conducted in Buenos Aires City, Argentina, in April 2005. According to consumers' perceptions, 67% were worried about their health, 79% take care in meals, 57% perceived the high risk of hormones and pesticides in food content and 91% of consumers are used to reading labels before or during their purchase. A Logit Binomial Regression Model was applied to explore which factors affected organic food consumption. The results yielded by this model suggest that the consumers with higher educational level, who eat healthy food, and consider food control organisms 'inefficient' are more likely to buy organic products. A high percentage of consumers read and trust label information in Argentina. This has interesting policy implications to promote differentiated and high value products, and to reduce information asymmetries.

description: The new institutional economics has recently developed the idea that the institutional environment can have an impact on economic actors' mental perceptions, and reciprocally, that these perceptions can impact on the institutional environment. This latter point seems particularly relevant in the field of economic organisations participation in the political making process. Nevertheless the empirical description of this role of mental perceptions in the political behaviour had not been made clearly. To contribute to this empirical description we lead a comparative study of 4 farm sectors in Costa Rica, based on a dynamic approach of mental perceptions in relation with the institutional change occurring during the liberalisation process. We carry out a statistical analysis of mental perceptions through a textual analysis of actors perceptions of the institutional change, leading to two main conclusions. Firstly we provide an empirical confirmation that mental models are influenced by specific institutional environments and lead to different strategies regarding the participation to the political making process. Secondly, we show that when an exogenous change occurs in the institutional environment, the mental models existing before the change can persist and lead to inefficient behaviours. This can partly explain part of the difficulties some sectors to lead efficient political activity that ensures their survival in a liberalized environment.

description: The paper assesses the extent to which sampling variation affects findings about Malmquist productivity change derived using Data Envelopment Analysis (DEA), in the first stage calculating productivity indices and in the second stage investigating the farm-specific change in productivity. Confidence intervals for Malmquist indices are constructed using Simar and Wilson's (1999) bootstrapping procedure. The main contribution of the paper is to account in the second stage for the information provided by the bootstrap in the first stage. The DEA standard errors of the Malmquist indices given by bootstrapping are employed in an innovative heteroscedastic panel regression, using a maximum likelihood procedure. The application is to a sample of 250 Polish farms over the period 1996-2000. The confidence interval's results suggest that contrary to what was reported by previous studies, the second half of 1990s for Polish farms was characterised not so much by productivity regress but rather by stagnation. As for the determinants of farm productivity change, we find that the integration of the DEA standard errors in the second-stage regression is significant in explaining a proportion of the variance in the error term. Although our heteroscedastic regression results differ with those from the standard Ordinary Least Squares, in terms of significance (fewer parameters are significant in our heteroscedastic regression) and sign (of the parameter of the share of other income in total income), they are consistent with theory and previous research. Family farms concentrating on farming experienced larger productivity progress than farms with hired labour and income diversification.

description: Quantum wells in InAs/GaSb heterostructures can be tuned to a topological regime associated with the quantum spin Hall effect, which arises due to an inverted band gap and hybridized electron and hole states. Here, we investigate electron-hole hybridization and the fate of the quantum spin Hall effect in a quasi one-dimensional geometry, realized in a core-shell-shell nanowire with an insulator core and InAs and GaSb shells. We calculate the band structure for an infinitely long nanowire using $\mathbf{k \cdot p}$ theory within the Kane model and the envelope function approximation, then map the result onto a BHZ model which is used to investigate finite-length wires. Clearly, quantum spin Hall edge states cannot appear in the core-shell-shell nanowires which lack one-dimensional edges, but in the inverted band-gap regime we find that the finite-length wires instead host localized states at the wire ends. These end states are not topologically protected, they are four-fold degenerate and split into two Kramers pairs in the presence of potential disorder along the axial direction. However, there is some remnant of the topological protection of the quantum spin Hall edge states in the sense that the end states are fully robust to (time-reversal preserving) angular disorder, as long as the bulk band gap is not closed.

description: We study the effect of diagonal and off-diagonal electron-phonon coupling in the ground state properties of the t-J model. Adiabatic and quantum phonons are considered using Lanczos techniques. Charge tiles and stripe phases with mobile holes (localized holes) are observed at intermediate (large) values of the diagonal electron-phonon coupling. The stripes are stabilized by half-breathing modes, while the tiles arise due to the development of extended breathing modes. Off-diagonal terms destabilize the charge inhomogeneous structures with mobile holes by renormalizing the diagonal coupling but do not produce new phases. Buckling modes are also studied and they seem to induce a gradual phase separation between hole rich and hole poor regions. The pairing correlations are strongly suppressed when the holes are localized. However, in charge inhomogeneous states with mobile holes no dramatic changes, compared with the uniform state, are observed in the pairing correlations indicating that D-wave pairing and moderate electron-phonon interactions can coexist.

description: The Punjab of India is an historical source of key wheat genetic resources in national and global plant breeding, and a focus of concerns about the abandonment of local varieties during the Green Revolution. Much of the wheat area in Punjab was already planted with earlier products of modern plant breeding programs when the Green Revolution began. These cultivars were more genetically similar and less productive than the semi-dwarf wheat varieties that succeeded them. We define, summarize and test indices of variety change and genetic diversity for the modern wheat varieties released and grown in Indian Punjab during the post-Green Revolution period. The first is the area-weighted average of varieties grown, which measures the rate of variety change, important means of counteracting the uniformity that can lead to pathogen mutation and plant diseases. Variety change is determined in large part by variety release and seed industry po licies. The second is the average coefficient of diversity, which measures the extent of dissimilarity among wheat varieties conferred through plant breeding. A generalized Cobb-Douglas production function is estimated with these indices specified as technical efficiency parameters, after testing for the exogeneity of each index. Findings support the hypothesis that slow variety age has counteracted the positive productivity effects brought about through diversifying the genetic base in wheat breeding in the post-Green Revolution period. Policies that speed the rate of variety change and make more equitable the spatial distribution of modern varieties could support, rather than detract from wheat productivity, reinforcing breeding successes.

Minimally-disturbing Heisenberg-Weyl symmetric measurements using hard-core collisions of Schrödinger particles

Year: 2005

description: In a previous paper we have presented a general scheme for the implementation of symmetric generalized measurements (POVMs) on a quantum computer. This scheme is based on representation theory of groups and methods to decompose matrices that intertwine two representations. We extend this scheme in such a way that the measurement is minimally disturbing, i.e., it changes the state vector \ketΨ of the system to \sqrtΠ \ketΨ where Πis the positive operator corresponding to the measured result. Using this method, we construct quantum circuits for measurements with Heisenberg-Weyl symmetry. A continuous generalization leads to a scheme for optimal simultaneous measurements of position and momentum of a Schr"odinger particle moving in one dimension such that the outcomes satisfy Δx Δp \geq \hbar. The particle to be measured collides with two probe particles, one for the position and the other for the momentum measurement. The position and momentum resolution can be tuned by the entangled joint state of the probe particles which is also generated by a collision with hard-core potential. The parameters of the POVM can then be controlled by the initial widths of the wave functions of the probe particles. We point out some formal similarities and differences to simultaneous measurements of quadrature amplitudes in quantum optics.

description: A characteristic feature of the 3d plaquette Ising model is its planar subsystem symmetry. The quantum version of this model has been shown to be related via a duality to the X-Cube model, which has been paradigmatic in the new and rapidly developing field of fractons. The relation between the 3d plaquette Ising and the X-Cube model is similar to that between the 2d quantum transverse spin Ising model and the Toric Code. Gauging the global symmetry in the case of the 2d Ising model and considering the gauge invariant sector of the high temperature phase leads to the Toric Code, whereas gauging the subsystem symmetry of the 3d quantum transverse spin plaquette Ising model leads to the X-Cube model. A non-standard dual formulation of the 3d plaquette Ising model which utilises three flavours of spins has recently been discussed in the context of dualising the fracton-free sector of the X-Cube model. In this paper we investigate the classical spin version of this non-standard dual Hamiltonian and discuss its properties in relation to the more familiar Ashkin-Teller-like dual and further related dual formulations involving both link and vertex spins and non-Ising spins.

Heart rate as a monitor for metabolic rate in captive juvenile steller sea lions (Eumetopias jubatus)
Creators: name: McPhee, Jan M.
Publisher: name: University of British Columbia
Year: 2009

description: The potential use of heart rate to monitor energy expenditure in free-ranging Steller sea lions (Eumetopias jubatus) was investigated by establishing whether a relationship exists between heart rate (fa) and oxygen consumption ( V 0 2 ) in captive sea lions while swimming and resting. Four trained Steller sea lions (2 males and 2 females; mass 87.4 -194.4 kg; ages 16 months-3 years) were equipped with a datalogger and two dorsal electrodes to record ECG (from which f[sub H] was calculated). Four styles of electrodes were developed and tested before selecting a final subcutaneous design. VO₂ (measured with open-circuit respirometry) was simultaneously recorded while the previously-fasted animal was at rest within an enclosed dry metabolic chamber or while it swam in an enclosed swim mill against water currents of various speeds (0-1.5 ms⁻¹). The mean regression equation describing the relationship between fa (beats min⁻¹) and VO₂ (ml min⁻¹ kg⁻⁰.⁷³) for all four animals was VO₂ = (0.68f[sub H] ± 0.07 s.e.) - (15.07 ± 6.20) (r²=0.72, p<0.01). The possibility that the fa/ VO₂ relationship could be affected by digestion was investigated by feeding one of the male Steller sea lions either 6 or 12 kg of herring prior to entering the swim mill. VO₂ increased over time after ingestion, while heart rate usually remained stable or decreased. The resulting relationship, VO₂ = (0.24f[sub H] ± 0.03) - (18.49 ± 02.68) (r²=0.19,p<0.01), differed significantly from the relationship derived while the animal was fasted, indicating that digestion may alter the relationship between f[sub H] and VO₂. Fasting and feeding intervals must therefore be taken into account when considering the use f[sub H]/VO₂ relationships to estimate energy expenditure from heart rate of free-ranging sea lions. The relationship demonstrated between f[sub H] and VO₂ while fasting suggests that heart rate can potentially be used to monitor energy consumption in free-ranging Steller sea lions. However, additional research should be conducted to further elucidate how the relationship is affected by such factors as digestion, sex, stress, and development.

description: We examine X-ray emission produced from hot gas during collisions and mergers of disk galaxies. To study this process, we employ simulations that incorporate cosmologically motivated disk-galaxy models and include the effects of radiative cooling, star formation, supernova feedback, and accreting supermassive black holes. We find that during a merger, the colliding gas in the disks is shock-heated to X-ray-emitting temperatures. The X-ray luminosity is spatially extended, rises during the initial stages of the merger, and peaks when the galactic centers coalesce. When a physical model for accreting black holes is included, the resulting feedback can drive powerful winds that contribute significantly to the amount and metallicity of hot gas, both of which increase the X-ray luminosity. In terms of their stellar kinematics and structural properties, the merger remnants in our simulations resemble elliptical galaxies. We find that the X-ray luminosities of the remnants with B-band luminosities in the range L_B ~ 10^10 - 10^11 Lsun are consistent with observations, while remnants with smaller or larger masses are underluminous in X-rays. Moreover, because the majority of the merger remnants are broadly consistent with the observed scaling relations between temperature, B-band luminosity and X-ray luminosity we conclude that major mergers are a viable mechanism for producing the X-ray halos of large, luminous elliptical galaxies.

description: Disentangled representation learning has recently attracted a significant amount of attention, particularly in the field of image representation learning. However, learning the disentangled representations behind a graph remains largely unexplored, especially for the attributed graph with both node and edge features. Disentanglement learning for graph generation has substantial new challenges including 1) the lack of graph deconvolution operations to jointly decode node and edge attributes; and 2) the difficulty in enforcing the disentanglement among latent factors that respectively influence: i) only nodes, ii) only edges, and iii) joint patterns between them. To address these challenges, we propose a new disentanglement enhancement framework for deep generative models for attributed graphs. In particular, a novel variational objective is proposed to disentangle the above three types of latent factors, with novel architecture for node and edge deconvolutions. Moreover, within each type, individual-factor-wise disentanglement is further enhanced, which is shown to be a generalization of the existing framework for images. Qualitative and quantitative experiments on both synthetic and real-world datasets demonstrate the effectiveness of the proposed model and its extensions.

description: The management of supply chains of the agri-food sector has become a very complex structure. Product variety has decreased, changes in legislatives and quality management requirements have a high influence, international trade is much higher, consumer demands about product freshness and food quality is fluctuate and processors and retailers ask for the implementation of quality systems. This has resulted in individual changes in the process and organisation level of the enterprises and in order to keep the costs minimal. The focus of this paper will be a cost-benefit analysis for the implementation of quality management/assurance systems. Only a few studies with the focus on HACCP and food safety exists in the part of costs and benefits of quality systems in the agri-food industry. And an approach with an integrated accomplishment of quality systems is still not publicised. With the view on this additional aspect a decision support model was developed. This model presents the requirements of existent quality, environmental and occupational health standards and is a basic for a cost benefit model for special scenarios and individual solutions for enterprises.

These results are preliminary due to the number of session (1) and participants (4). They include a technical assessment of the performance of Openpose, as well as a preliminary user study to confirm our game scenario could elicit the expected response from subjects.

description: We present the results of ROSAT and XMM-Newton observations of the recurrent ultraluminous X-ray source (ULX) NGC 253 ULX1. This transient is one of the few ULXs that was detected during several outbursts. The luminosity reached 1.4 10^39 erg s^-1 and 0.5 10^39 erg s^-1 in the detections by ROSAT and XMM-Newton, respectively, indicating a black hole X-ray binary with a mass of the compact object of >11 M_sun. It is highly unlikely that this source is a foreground source or a background AGN. In the ROSAT detection NGC 253 ULX1 showed significant variability, whereas the luminosity was constant in the detection from XMM-Newton. The XMM-Newton EPIC spectra are well-fit by a bremsstrahlung model (kT=2.24 keV, N_H=1.74 10^20 cm^-2), which can be used to describe a comptonized plasma. No counterpart was detected in the optical I, R, B, NUV and FUV bands to limits of 22.9, 24.2, 24.3, 22 and 23 mag, respectively, pointing at a X-ray binary with a low mass companion.

description: Advanced perception and path planning are at the core for any self-driving vehicle. Autonomous vehicles need to understand the scene and intentions of other road users for safe motion planning. For urban use cases it is very important to perceive and predict the intentions of pedestrians, cyclists, scooters, etc., classified as vulnerable road users (VRU). Intent is a combination of pedestrian activities and long term trajectories defining their future motion. In this paper we propose a multi-task learning model to predict pedestrian actions, crossing intent and forecast their future path from video sequences. We have trained the model on naturalistic driving open-source JAAD dataset, which is rich in behavioral annotations and real world scenarios. Experimental results show state-of-the-art performance on JAAD dataset and how we can benefit from jointly learning and predicting actions and trajectories using 2D human pose features and scene context.

description: We propose a time-dependent photonic structure, in which the carrier frequency of an optical pulse is shifted without changing its shape. The efficiency of the device takes advantage of slow group velocities of light attainable in periodic photonic structures. The frequency shifting effect is quantitatively studied by means of Finite Difference Time Domain simulations for realistic systems with optical parameters of conventional silicon technology.

subject: Kenya

description: This paper characterises smallholder milk outlets in Nakuru district one of the major milk producing Districts in Kenya, and also analyses factors that influence their current operating and handling capacities. Data comes from four divisions of the district. A sample of 137 smallholder milk retail outlets was made using systematic random sampling methodology. Both descriptive and ordinary regression methods were used in the analysis. A characterisation of the retail outlets is brought out and the factors that affect their current operating capacities presented. Results show that a unit change in education, experience and selling prices leads to 0.29, 0.18 and 0.23 significant changes in milk handling capacities by the retail outlets respectively. These imply that there is an efficiency gain from education and better prices through higher consumer incomes in the industry. Enhancement of milk retailers' value addition through provision of physical facilities such as cooling equipment and stability in prices should be encouraged through policy intervention to promote informal sector investments in the sub-sector.
Neural network parametrization of the lepton energy spectrum in semileptonic B meson decays

description: We construct a parametrization of the lepton energy spectrum in inclusive semileptonic decays of B mesons, based on the available experimental information: moments of the spectrum with cuts, their errors and their correlations, together with kinematical constraints. The result is obtained in the form of a Monte Carlo sample of neural networks trained on replicas of the experimental data, which represents the probability density in the space of lepton energy spectra. This parametrization is then used to extract the b quark mass m_b^{1S} in a way that theoretical uncertainties are minimized, for which the value m_b^{1S}=4.84 \pm 0.14^{exp}\pm 0.05^{th} GeV is obtained.

description: An increasing scarcity of water for crop farming and livestock watering among agropastoralists of Mieso in Eastern Ethiopia has largely disrupted their livelihoods. Indigenous water well maintenance and government initiated rainwater harvesting are two important collective actions common among these communities. With the aim of examining collective action institutions in both cases, we collected data from different stakeholders and individual members. Theoretically, low level of physical assets (action resource) limits participation of an individual in collective action. In our case, other factors such as environmental uncertainty and lower level of dependence on the resource have been found to be more significant in limiting membership than limitation of assets. Poor agropastoralists depend on their informal networks to have access to other assets. This enables them to maintain their membership. Moreover, there is a difference between self-organized and imposed collective action in terms of rule enforcement and sanctioning. Institutions also produce different incentives in that free riding leads to automatic exclusion in water harvesting, whereas poor free riding members continue benefiting from the water well. In evaluating the success, we conclude that technical capacity of members in benefiting from their collective action is limited and deserves more attention than their ability to develop effective collective action institutions. Technical capacity development of user groups needs to be central in policy and programs addressing this.
Searching for axion-like particles under strong gravitational lenses

description: We establish strong gravitational lens systems as robust probes of axion-like particles (ALPs) -- a candidate for dark matter. A tiny interaction of photons with ALPs induces birefringence. Multiple images of gravitationally lensed polarised objects allow differential birefringence measurement, alleviating systematics and astrophysical dependencies. We apply this novel method to the lens system CLASS B1152+199 and constrain ALP-photon coupling $\le 9.2\times 10^{-11}\, {\rm GeV}^{-1} \textrm{ to } 7.7\times 10^{-8}\, {\rm GeV}^{-1}$ ($95\%$ C.L.) for ALP mass between $3.6\times 10^{-21} \,{\rm eV}$ and $4.6 \times 10^{-18} \,{\rm eV}$. A larger sample will improve the constraints.

description: Land and water are the natural partners in the process of agricultural development. Their coordinated use is essen tial for long-term optimization of economic as well as social welfare. Deliberately planned or policy induced divergence from integrated land and water use management may bring short-term rewards but normally squeezes the long-term sustainability of growth as well as of resources. The Indian Punjab, known as the Heartland of Green Revolution, is a classic example of this. Punjab has depleted its land and water resources due to lack of their integrated use. The production pattern followed was neither commensurate with soil capabilities nor with water availability not to talk about their integrated capacities. The production, inputs use, pricing, marketing and other policies never focused upon the integrated sustainable land and water use management. The concentration of price support policy, assured marketing, input subsidization etc. on rice and wheat established the mono culture of high water requiring and nutrient exhausting rice-wheat crop rotation. This paper attempts to review the policies responsible for this situation and suggests a reformulation of the policies promoting sustainable land and water use. The poster presentation of the paper has been divided into five sections including first introductory section. Second section provides the profile of agricultural economy of the state. Third section deals with the policies, which prohibited the coordinated use of land and water. Fourth section reviews the impact of these policies on soil degradation and water depletion. In the fifth section an attempt has been made to put forward the policies and other remedial measures to correct the situation.

description: We consider a standard \textit{susceptible-infected-susceptible} (SIS) model to study behaviors of steady states of epidemic spreading in small-world networks. Using analytical methods and large scale simulations, we recover the usual epidemic behavior with a critical threshold $λ_{c}$ below which infectious diseases die out. Whereas for the spreading rate $λ$ far above $λ_{c}$, it was found that the density of infected individuals $ρ$ as a function of $λ$ has the property $ρ\approx F(K)(\ln λ- \ln λ_{c})$.
