description: Silicon photomultipliers (SiPMs) have a low radioactivity, compact geometry, low operation voltage, and reasonable photo-detection efficiency for vacuum ultraviolet light (VUV). Therefore it has the potential to replace photomultiplier tubes (PMTs) for future dark matter experiments with liquid xenon (LXe). However, SiPMs have nearly two orders of magnitude higher dark count rate (DCR) compared to that of PMTs at the LXe temperature ($\sim$ 165 K). This type of high DCR mainly originates from the carriers that are generated by band-to-band tunneling effect. To suppress the tunneling effect, we have developed a new SiPM with lowered electric field strength in cooperation with Hamamatsu Photonics K. K. and characterized its performance in a temperature range of 153 K to 298 K. We demonstrated that the newly developed SiPMs had 6--54 times lower DCR at low temperatures compared to that of the conventional SiPMs.

description: Ethiopia holds large potential for dairy development due to its large livestock population, the favorable climate for improved, high-yielding animal breeds, and the relatively disease-free environment for livestock. Given the considerable potential for smallholder income and employment generation from high-value dairy products, development of the dairy sector in Ethiopia can contribute significantly to poverty alleviation and nutrition in the country. Like other sectors of the economy, the dairy sector in Ethiopia has passed through three phases or turning points, following the economic and political policy in the country. In the most recent phase, characterized by the transition towards market-oriented economy, the dairy sector appears to be moving towards a takeoff stage. Liberalized markets and private sector investment and promotion of smallholder dairy are the main features of this phase. Milk production during the 1990s expanded at an annual rate of 3.0 percent compared to 1.63-1.66 percent during the preceding three decades. Review of the development of dairy sector in Ethiopia indicates that there is a need to focus interventions more coherently. Development interventions should be aimed at addressing both technological gaps and marketing problems. Integration of crossbred cattle to the sector is imperative for dairy development in the country. This can be achieved either through promotion of large private investment to introduce new technology in the sector such as improved genotypes, feed and processing, and promotion of integration of crossbred cattle into the smallholder sector through improving their access to improved cattle breeds, AI service, veterinary service, and credit. Similarly, government should also take the lead in building infrastructure and providing technical service to smallholders. Severe shortages, low quality and seasonal unavailability of feed likewise remain as major constraints to livestock production in Ethiopia. These constraints need to be addressed and technological change be promoted to increase milk production.

description: We conducted on-farm trials in the southern Guinea savannah of Ghana in 2016 and 2017 to evaluate soyabean response to three fertiliser blends to guide farmers towards profitable adoption of appropriate phosphorus fertiliser blend for improved soyabean production. Old Yara Legume, New Yara Legume and Triple Superphosphate fertiliser blends were evaluated. In both years, the phosphorus fertiliser blends were evaluated in a Randomised Complete Block Design with 20, 30, and 40 kg P ha−1 application rates together with control. Phosphorus fertiliser application increased soyabean yields by 1 070 kg ha−1. In 2016, fertiliser blend use efficiency ranged from 2.9 kg grain per kg fertiliser blend applied with the New Yara Legume applied at 40 kg P ha−1 to 7.4 kg grain per kg fertiliser blend applied with the Triple Superphosphate applied at 40 kg P ha−1 with significant differences between treatments. In 2017, blend use efficiency ranged from 2.5 kg grain per kg fertiliser blend applied with Old Yara Legume applied at 40 kg P ha−1 to 9.2 kg grain per kg fertiliser blend applied with the Triple Superphosphate applied at 40 kg P ha−1 with significant differences between treatments. However, phosphorus use efficiency did not significantly differ between the different treatments both in the 2016 and 2017 trials. In both 2016 and 2017 trials, the highest benefit cost ratio was attained at the lowest application rate for all the three fertiliser blends suggesting the need to review the current application rate of 30 kg P fertiliser ha−1 promoted in northern Ghana. Furthermore, the provision of credit and/or subsidy for farmers by the government is required to enable uptake and utilisation of fertilisers by farmers.

description: In this work we focus on the challenges of perceiving and coordinating spatial actions between humans and robots in production systems. We address the fundamental questions of how the affective states of individuals in the production process can be visually captured and interpreted in order to facilitate intuitive interactions without explicit commands. Additionally, we investigate methods to analyze the environment and action context in a semantic scene to anticipate user and action intentions. Lastly, we formulate decision approaches to derive appropriate interaction strategies based on affective user states and intentions in the scene context to improve productive collaboration between humans and robots in production environments. By addressing these challenges, this work aims to improve the efficiency of productive teaming processes in production systems.

description: From a theoretical perspective crop yields should tend to converge over time and space as: growth in yield potential exhibits diminishing returns; an increasing share of farmers shift to using high yielding varieties (HYVs); barriers to the free flow of knowledge and information are removed; and significant investments continue to be made in supporting institutions whose mandates include facilitating and accelerating the cross-border flow of improved agricultural technologies. Using a new, sub-national crop yield database for Latin America and the Caribbean (LAC) we examine whether convergence is indeed occurring, and discover it is not. On the contrary, there is evidence of divergence. We test three hypotheses that might help account for this finding: that technology generation has been biased towards production in more-favored production systems leaving behind persistent pockets of production in more marginal lands; that rainfall patterns have changed in ways that exacerbate yield divergence, and that technology spillover across borders remains more problematic than within-country spillover. We find evidence to support all three of these hypotheses. Further work is needed to assess the relative importance of these sources of yield divergence both across and within LAC. As anticipated, rainfall variability is poorly linked to the variability of irrigated crop yields, but more strongly linked to variability in rainfed crops. The results suggest while some countries and regions within countries forge ahead with crop yield improvements there are many areas, often in smaller countries, where the livelihoods of many farmers - and likely a disproportionate share of LAC’s rural poor - continue to be constrained by low-productivity agriculture. There remains significant work ahead for national governments and for publicly-funded regional and international agricultural technology institutions to remedy this situation.
Understanding the environmental factors that have an impact on employee well-being : a social audit of a university college
Creators: name: Gurm, Balbir Kaur
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this research was to study the effects of the environment, especially the work environment, on employee well-being in order to identify ways in which the environment may be improved. Key elements of a methodology called social and ethical auditing and accounting (social auditing) were used to determine the impact of a university college's policies and practices (environment) on employees' (faculty, support staff, and administration) wellbeing. Focus groups were conducted to determine which policies and practices employees believed affected their well-being. Most factors identified were consistent with the Determinants of Health in the Workplace Framework (Polanyi et al., 1998). Data from the focus groups was used to create a social audit survey that was administered to all employees at the university college. The response rate was 39% or 450 respondents. Generally the employees reported a high level of health or well-being. They also believed the organization was a good place to work. Employees had a sense of autonomy, control, belonging and caring. The employees perceived a low level of trust, communication, and organizational justice. They also reported that their stress and workload had increased over the last year, yet they were able to balance their work life and personal life. Recommendations made include actions to increase trust and communication, ensure the practices in the organization are fair and equitable, and monitor stress and workload.

description: Deep neural networks are known to be overconfident when applied to out-of-distribution (OOD) inputs which clearly do not belong to any class. This is a problem in safety-critical applications since a reliable assessment of the uncertainty of a classifier is a key property, allowing the system to trigger human intervention or to transfer into a safe state. In this paper, we aim for certifiable worst case guarantees for OOD detection by enforcing not only low confidence at the OOD point but also in an $l_\infty$-ball around it. For this purpose, we use interval bound propagation (IBP) to upper bound the maximal confidence in the $l_\infty$-ball and minimize this upper bound during training time. We show that non-trivial bounds on the confidence for OOD data generalizing beyond the OOD dataset seen at training time are possible. Moreover, in contrast to certified adversarial robustness which typically comes with significant loss in prediction performance, certified guarantees for worst case OOD detection are possible without much loss in accuracy.

description: We report a comprehensive investigation of the effects of quantum turbulence and quantized vorticity in superfluid $^4$He on the motion of a micro-electromechanical systems (MEMS) resonator. We find that the MEMS is uniquely sensitive to quantum turbulence present in the fluid. To generate turbulence in the fluid, a quartz tuning fork (TF) is placed in proximity to the MEMS and driven at large amplitude. We observe that at low velocity, the MEMS is damped by the turbulence, and that above a critical velocity, $v_c \simeq 5\,$mm\,s$^{-1}$, the turbulent damping is greatly reduced. We find that above $v_c$, the damping of the MEMS is reduced further for increasing velocity, indicating a velocity dependent coupling between the surface of the MEMS and the quantized vortices constituting the turbulence. We propose a model of the interaction between vortices in the fluid and the surface of the MEMS. The sensitivity of these devices to a small number of vortices and the almost unlimited customization of MEMS open the door to a more complete understanding of the interaction between quantized vortices and oscillating structures, which in turn provides a new route for the investigation of the dynamics of single vortices.

description: Climate volatility affects agricultural variability, and extreme climate outcomes have the potential to detrimentally affect food supply and prices in a given country. International trade has the potential to reduce the impacts of climate-induced food production variability, although it may further expose the country to international price volatility. This study focuses on Tanzania and finds that global production volatility currently has very little effect on domestic grain prices due to the country’s limited integration with the international grains market. Almost all the price volatility in grains is attributable to domestic production volatility. At the same time, an export ban that was a response to the 2007-2008 food price crisis increases potential domestic grains price volatility. Rural agricultural households that are net sellers of grains, or rely on revenue from grains production as their primary source of income, may be particularly vulnerable to high income volatility through climate-induced production variability. If Tanzania experiences extremely positive shocks to grains production – due to exceptionally good climate outcomes for example – total revenue from grain falls by 2 percent under the 2001 national trade regime, with the revenue decline becoming 5 percent if there is an export ban on grains.

Optical monitoring of their spontaneous decay can display either Zeno or anti-Zeno deviations from the Golden Rule, and thereby probe the temporal correlations of elementary excitations in BECs.

description: This research evaluates the impact of interactive technologies on consumer experiences in the hospitality and tourism sector. It specifically addresses technology adoption behaviors, interactive technology design, and privacy concerns associated with information disclosure. Chapter 1 conducts a meta-analysis of technology research published in top hospitality and tourism journals from 2000 to 2021. This analysis identifies critical factors influencing consumers' technology experiences and pinpoints design and privacy concerns as significant gaps in current research. Building on these insights, Chapter 2 delves into the design elements of technologies like service robots, addressing the gaps by taking a holistic approach to service robot design. The findings underscore the importance of design congruency in the deployment of service robots, providing practical insights and guidelines for industry stakeholders to optimize investments in such technologies. Chapter 3 employs an exploratory sequential mixed-methods approach to compare consumer private information disclosure behavior during interactions with technological and human service agents in the travel sector. This study indicates that technological agents are perceived as more competent, whereas human agents are trusted more for their integrity and benevolence in matters of information privacy. Together, these insights are crucial for service providers, technology developers, and policymakers as they seek to enhance consumer satisfaction and operational efficiency within the hospitality and tourism industry.

description: This paper presents the initial concept for an evaluation framework to systematically evaluate productive teaming (PT). We consider PT as adaptive human-machine interactions between human users and augmented technical production systems. Also, human-to-human communication as part of a hybrid team with multiple human actors is considered, as well as human-human and human-machine communication for remote and mixed remote- and co-located teams. The evaluation comprises objective, performance-related success indicators, behavioral metadata, and measures of human experience. In particular, it considers affective, attentional and intentional states of human team members, their influence on interaction dynamics in the team, and researches appropriate strategies to satisfyingly adjust dysfunctional dynamics, using concepts of companion technology. The timescales under consideration span from seconds to several minutes, with selected studies targeting hour-long interactions and longer-term effects such as effort and fatigue. Two example PT scenarios will be discussed in more detail. To enable generalization and a systematic evaluation, the scenarios’ use cases will be decomposed into more general modules of interaction.

description: The product development process could benefit from a synergistic human-machine teaming, potentially shortening product development cycles and improving product performance and sustainability. However, there is a lack of available methods to achieve this goal. A technical product has to satisfy numerous requirements. Due to the variety and complexity of these requirements, the design process is challenging for human engineers. While engineers are supported by various tools (e.g. FEM) for analyzing product properties, tools for computer-aided synthesis of product properties considering the corresponding requirements are still only available in exceptional cases. However, such synthesis capabilities are necessary to qualify a computer-aided tool for productive teaming with engineers. Special methods based on artificial intelligence show a high potential for general computer-aided synthesis methods. This contribution presents an innovative approach in this direction based on topology optimization techniques.

description: This paper presents a general equilibrium analysis of the optimal allocation of land to be preserved as natural habitat for conservation and recreation. Following Anas (1988) we model the natural habitat as both a congestible public good due to recreation visits and a pure public good due to option and existence values. Following Fullerton and Kinnaman (1995) we analyze the use of tax instruments to achieve the first best outcome in a private competitive market. First we present the scenario where the public good, the environment, is provided by a government or conservation agency. We show that a per unit lump sum tax on the environment similar to Anas (1988) combined with a recreation tax or a wage subsidy can achieve the first best allocation. Given the difficulty of charging a lump sum tax we next show that combining the wage or recreation tax with a utility maximizing conservation agency achieves the first best outcome. Next we present the scenario where the public good, the environment, is privately provided. We show that a subsidy on the private land set aside for the environment combined with a recreation or wage tax can achieve the first best outcome. Given the growing interest in ecosystem service markets and in providing ecosystem services this analysis highlights that tax instruments can be used to provide the optimal amount of land devoted to the environment.

description: Due to their adaptability, mobility, and capacity to offer an ideal channel, unmanned aerial vehicles (UAVs) have become a potential option for wireless power transfer and data collection in wireless sensor networks (WSNs). This paper examines energy-constrained WSNs, where data transfer to the data center is facilitated by UAV and sensors rely on radio frequency (RF) energy obtained by a Power Beacon (PB). However, due to energy limitations, sensors can only send data using the harvested energy. We consider a WSN in which the nodes are randomly distributed within a circular area, with the PB placed at the center of the WSN. To evaluate the system performance, we consider the dynamic nature of the wireless channel, which includes factors such as signal reflection, scattering, and diffraction. Through numerical analysis and simulations, the main aim is to identify the optimal system parameters that minimize the outage probability. This analysis provides valuable insights for designing more effective and reliable energy-harvesting WSNs with UAV as data collector. By leveraging UAV in WSNs, system performance can be improved, ensuring data transmission to destination nodes placed at a large distance from the WSN.

description: It is possible to tune the scattering length for the collision of ultra-cold 1S0 ground state alkaline-earth atoms using an optical Feshbach resonance. This is achieved with a laser far detuned from an excited molecular level near the frequency of the atomic intercombination 1S0--3P1 transition. Simple resonant scattering theory, illustrated by the example of 40Ca, allows an estimate of the magnitude of the effect. Unlike alkali metal species, large changes of the scattering length are possible while atom loss remains small, because of the very narrow line width of the molecular photoassociation transition. This raises prospects for control of atomic interactions for a system without magnetically tunable Feshbach resonance levels.

description: GM corn seed companies have innovated continuously with the introduction of new traits and, more recently, with the creation of stacked varieties, which combine more than one trait. This work develops a Bayesian model of adoption dynamics that demonstrates how uncertainty with a package technology with known risk can lead to a sequential adoption pattern in which farmers adopt a single component first. We then develop a semiparametric panel data model of adoption dynamics to measure the effects of experience with single trait (non-stacked) varieties on the adoption of stacked varieties. The results underscore the importance of early experience with the non-stacked technology in the subsequent adoption of stacked varieties, i.e., a sequential adoption process. There is also evidence that farmers with more human capital tend to learn faster from own experience and that as the GM corn-technology diffusion process deepens, the importance of early experience decreases.

description: Climate is known for being characterised by strong non-linearity and chaotic behaviour. Nevertheless, few studies in climate science adopt statistical methods specifically designed for non-stationary or non-linear systems. Here we show how the use of statistical methods from Information Theory can describe the non-stationary behaviour of climate fields, unveiling spatial and temporal patterns that may otherwise be difficult to recognize. We study the maximum temperature at two meters above ground using the NCEP CDAS1 daily reanalysis data, with a spatial resolution of 2.5 by 2.5 degree and covering the time period from 1 January 1948 to 30 November 2018. The spatial and temporal evolution of the temperature time series are retrieved using the Fisher Information Measure, which quantifies the information in a signal, and the Shannon Entropy Power, which is a measure of its uncertainty -- or unpredictability. The results describe the temporal behaviour of the analysed variable. Our findings suggest that tropical and temperate zones are now characterized by higher levels of entropy. Finally, Fisher-Shannon Complexity is introduced and applied to study the evolution of the daily maximum surface temperature distributions.

description: This work analyzes the effects of ethnic heterogeneity on credit and entrepreneurship in The Gambia. We develop a model of credit transactions based on ethnic density, which shows that where formal credit markets fail denser ethnic groups will have better access to credit. This work places a special emphasis on the Serahule ethnic group, which is ethnically dense and entrepreneurially successful. Our results show that Serahule-owned enterprises are indeed larger and more profitable. Furthermore, their marginal rate of return of capital is significantly lower than that of enterprises owned by other ethnicities, as one would expect with lower credit constraints.

description: We consider the influence of (milli/micro)lensing on the spectra of lensed QSOs. We propose a method for the observational detection of microlensing in the spectra of lensed QSOs and apply it to the spectra of the three lensed QSOs (PG 1115+080, QSO 1413+117 and QSO 0957+561) observed with Hubble Space Telescope (HST). We find that the flux ratio between images A1 and A2 of PG 1115+080 is wavelength-dependent and shows differential magnification between the emission lines and the continuum. We interpret this magnification as arising from millilensing. We also find that the temporal variations in the continuum of image C of QSO 1413+117 may be caused by microlensing, while the temporal variation observed in QSO 0957+561 was probably an intrinsic one.

description: Atmospheric free space and fiber have been widely exploited as the channels for quantum communication, and have enabled inter-continent and inter-city applications. Air-sea free-space channel, being capable of linking the satellite-based quantum resource and underwater vehicle, has now become the last piece of the puzzle in building global quantum communication network. However, long-distance quantum communication penetrating water up to tens to hundreds of meters is extremely challenging due to the inevitable high loss. Here, we present an experimental demonstration of underwater decoy-state quantum key distribution against high loss, meanwhile keep a low quantum bit error rate less than 2.5% for different distances. By directly modulating blue-green lasers at a high speed of 50MHz and decoy-state protocol, we are able to for the first time reach a long-distance quantum key distribution that is unconditionally secure and can enable real-life air-sea quantum communication tasks. The demonstrated distance, even in coastal water of Jerlov types 2C, is up to 30 meters, about one-order improvement over the proof-in-principle demonstrations in previous experiments, and the channel loss is equivalent to 345-meter-long clean seawater of Jerlov type I, representing a key step forward to practical air-sea quantum communication.

description: Future production technologies will comprise a multitude of systems whose core functionality is closely related to machine-learned models. Such systems require reliable components to ensure the safety of workers and their trust in the systems. The evaluation of the functional reliability and resilience of systems based on machine-learned models is generally challenging. For this purpose, appropriate test data must be available, which also includes abnormal cases. These abnormal cases can be unexpected usage scenarios, erroneous inputs, accidents during operation or even the failure of certain subcomponents. In this work, approaches to the model-based generation of an arbitrary abundance of data representing such abnormal cases are explored. Such computer-based generation requires domain-specific approaches, especially with respect to the nature and distribution of the data, protocols used, or domain-specific communication structures. In previous work, we found that different use cases impose different requirements on synthetic data, and the requirements in turn imply different generation methods [1]. Based on this, various use cases are identified and different methods for computer-based generation of realistic data, as well as for the quality assessment of such data, are explored. Ultimately we explore the use of Federated Learning (FL) to address data privacy and security challenges in Industrial Control Systems. FL enables local model training while keeping sensitive information decentralized and private to their owners. In detail, we investigate whether FL can benefit clients with limited knowledge by leveraging collaboratively trained models that aggregate client-specific knowledge distributions. We found that in such scenarios federated training results in a significant increase in classification accuracy by 31.3% compared to isolated local training. Furthermore, as we introduce Differential Privacy, the resulting model achieves on par accuracy of 99.62% to an idealized case where data is independent and identically distributed across clients.

description: The emergence of smart products has led to the development of an increasing number of multidisciplinary systems. For the successful development of such systems, a holistic approach is necessary, such as model-based systems engineering (MBSE). It is argued that certain product development activities could be integrated and improved with MBSE, one such activity being the assessment of environmental impacts. This article presents a case study on the usage of Life Cycle Assessment (LCA) on a MBSE system model. In the study a technical system is modelled with views according to the MagicGRID approach. The scope and goal of the LCA are defined by using SysML diagrams and elements. Additionally, different system variants are modelled to explore the capability of comparing LCA studies. At the end of the case study, the benefits, limitations, and shortcomings of the integration are discussed.

description: One of the main ingredients in most quantum information protocols is a reliable source of two entangled systems. Such systems have been generated experimentally several years ago for light but has only in the past few years been demonstrated for atomic systems. None of these approaches however involve two atomic systems situated in separate environments. This is necessary for the creation of entanglement over arbitrary distances which is required for many quantum information protocols such as atomic teleportation. We present an experimental realization of such distant entanglement based on an adaptation of the entanglement of macroscopic gas samples containing about 10^11 cesium atoms shown previously by our group. The entanglement is generated via the off-resonant Kerr interaction between the atomic samples and a pulse of light. The achieved entanglement distance is 0.35m but can be scaled arbitrarily. The feasibility of an implementation of various quantum information protocols using macroscopic samples of atoms has therefore been greatly increased. We also present a theoretical modeling in terms of canonical position and momentum operators X and P describing the entanglement generation and verification in presence of decoherence mechanisms.

description: Excerpts from the report Summary: This report covers the findings of a study, made in Iowa during 1952 and 1953, of costs of storing reserves of corn at country elevators, at bin sites, and on farms. The objective of this study was to measure and compare the costs of storing corn in alternative locations and types of structures. The problem was one of measuring storage costs in existing plants rather than one of minimizing costs or maximizing storage income within the plants. The data collected included information on volume and costs but not on profits or margins. Consequently, the study provides no basis for a comparison of the marginal productivity of resources allocated to the storage operation or to other departments within the elevator plants studied. It was not designed to do so. Total and average storage costs are assumed to be continuous functions of plant volume which are not constant over the entire volume range. Therefore, this study was directed toward the description of the shape as well as the level of cost curves associated with the storage function.
