description: Non-supersymmetric Grand Unified $SO(10)\times U(1)_{\rm PQ}$ models have all the ingredients to solve several fundamental problems of particle physics and cosmology -- neutrino masses and mixing, baryogenesis, the non-observation of strong CP violation, dark matter, inflation -- in one stroke. The axion - the pseudo Nambu-Goldstone boson arising from the spontaneous breaking of the $U(1)_{\rm PQ}$ Peccei-Quinn symmetry - is the prime dark matter candidate in this setup. We determine the axion mass and the low energy couplings of the axion to the Standard Model particles, in terms of the relevant gauge symmetry breaking scales. We work out the constraints imposed on the latter by gauge coupling unification. We discuss the cosmological and phenomenological implications.

description: In today's business environment, multiple organizations routinely work collaboratively in pursuit of a single mission. These separate efforts result in process and programmatic complexity that is difficult to manage effectively. Mission success in these complex settings demands a collaborative management approach that effectively coordinates task execution and decision-making activities among all participating groups. Managing for mission success requires establishing and maintaining a reasonable degree of confidence that a mission's objectives will be successfully achieved. Confidence at the mission level requires establishing and maintaining a corresponding level of confidence in the people, processes, and technologies used to achieve a mission. The Software Engineering Institute (SEI) is currently developing the Mission-Oriented Success Analysis and Improvement Criteria (MOSAIC)—a suite of advanced, risk-based analysis methods for assessing complex, distributed programs, processes, and information-technology systems. With SEI MOSAIC methods, management can establish and maintain confidence in success throughout the life cycle and help provide assurance at the mission, system, and program levels. This technical note provides an executive overview of the concepts and foundations of SEI MOSAIC.

description: One of the most promising strategies to identify the nature of dark matter consists in the search for new particles at accelerators and with so-called direct detection experiments. Working within the framework of simplified models, and making use of machine learning tools to speed up statistical inference, we address the question of what we can learn about dark matter from a detection at the LHC and a forthcoming direct detection experiment. We show that with a combination of accelerator and direct detection data, it is possible to identify newly discovered particles as dark matter, by reconstructing their relic density assuming they are weakly interacting massive particles (WIMPs) thermally produced in the early Universe, and demonstrating that it is consistent with the measured dark matter abundance. An inconsistency between these two quantities would instead point either towards additional physics in the dark sector, or towards a non-standard cosmology, with a thermal history substantially different from that of the standard cosmological model.

description: The variability of wind power supply can present substantial challenges to incorporating wind power into a grid system. Thus, Wind Power Forecasting (WPF) has been widely recognized as one of the most critical issues in wind power integration and operation. There has been an explosion of studies on wind power forecasting problems in the past decades. Nevertheless, how to well handle the WPF problem is still challenging, since high prediction accuracy is always demanded to ensure grid stability and security of supply. We present a unique Spatial Dynamic Wind Power Forecasting dataset: SDWPF, which includes the spatial distribution of wind turbines, as well as the dynamic context factors. Whereas, most of the existing datasets have only a small number of wind turbines without knowing the locations and context information of wind turbines at a fine-grained time scale. By contrast, SDWPF provides the wind power data of 134 wind turbines from a wind farm over half a year with their relative positions and internal statuses. We use this dataset to launch the Baidu KDD Cup 2022 to examine the limit of current WPF solutions. The dataset is released at https://aistudio.baidu.com/aistudio/competition/detail/152/0/datasets.

description: A fundamental truth of system design is that, in the absence of countermeasures, a system's security and survivability will degrade over time. Changes in the environment or usage of a system, or changes to the elements that compose the system, often introduce new or elevated threats that the system was not designed to handle and is ill-prepared to defend itself against. The first step in evolving to meet new threats to your system's security and survivability is to recognize the need to modify your system, that is, to recognize changes in security and survivability risks that trigger the need to enter the evolution phase of the system development life cycle. It is essential that significant risk management resources be devoted to the ongoing evolution of any mission-critical system. The successful evolutionary design of a secure and survivable system is dependent on the continual monitoring of the system and its environment to detect changes that may affect the risk management assumptions on which the system's security and survivability are founded.

description: Weed suppression is a potential benefit of cover crop mixtures, as species diversity may allow for combining early and late-season competition with weeds. Here, we studied if this is possible for only-legume mixtures containing species with different growth rates, by testing two legumes, alsike clover (AC; Trifolium hybridum L.) and black medic (BM; Medicago lupulina L.) in two field trials sown in 2016 and 2017. Five AC:BM ratios (100:0, 67:33, 50:50, 33:67, and 0:100) were grown at three densities (50%, 100%, and 150% of recommended seed density). Cover crop and weed aboveground biomass (CCB and WB, respectively) were harvested three times, after establishment in spring (H1), in summer (H2), and in autumn after mulching (H3). Compared to fallow plots, all monocultures and mixtures showed early-season weed suppression in terms of biomass production and more efficiency over time with an average reduction of 42%, 52%, and 96% in 2016, and 39%, 55%, and 89% in 2017 at H1, H2, and H3, respectively. Out of 54 mixture treatments, only eight mixtures showed stronger weed suppression than monocultures. Mixtures reduced WB by 28%, as an average value, in 2017 compared to the respective monocultures, but not significantly in 2016, indicating that the crop diversity effect on weeds was dependent on the growing environment. Weed suppression was significantly higher at 100% and 150% seed density than 50%, but no significant differences were determined between 100% and 150% seed density. After mulching, no density effect was observed on CCB and WB. In conclusion, AC and BM can be used as a keystone species on weed suppression for sustainable agriculture as they possess plasticity to suppress weeds when higher biomass productivity is limited by environmental conditions. However, their diversity effects are time and condition dependent. Appropriate seed density and mulching can successfully be employed in weed management, but seed density may not have an effect after mulching.

description: Geothermal district heating development has been gaining momentum in Europe with numerous deep geothermal installations and projects currently under development. With the increasing density of geothermal wells, questions related to the optimal and sustainable reservoir exploitation become more and more important. A quantitative understanding of the complex thermo-hydraulic interaction between tightly deployed geothermal wells in heterogeneous temperature and permeability fields is key for a maximum sustainable use of geothermal resources. Motivated by the geological settings of the Upper Jurassic aquifer in the Greater Munich region, we develop a computational model based on finite element analysis and gradient-free optimization to simulate groundwater flow and heat transport in hot sedimentary aquifers, and investigate numerically the optimal positioning and spacing of multi-well systems. Based on our numerical simulations, net energy production from deep geothermal reservoirs in sedimentary basins by smart geothermal multi-well arrangements provides significant amounts of energy to meet heat demand in highly urbanized regions. Our results show that taking into account heterogeneous permeability structures and variable reservoir temperature may drastically affect the results in the optimal configuration. We demonstrate that the proposed numerical framework is able to efficiently handle generic geometrical and geologocal configurations, and can be thus flexibly used in the context of multi-variable optimization problems. Hence, this numerical framework can be used to assess the extractable geothermal energy from heterogeneous deep geothermal reservoirs by the optimized deployment of smart multi-well systems.

Por tanto, si contrario con lo esperado, los operadores judiciales resuelven no usar el enfoque de género, causará revictimización a la mujer materializada en una providencia judicial, bien sea por el uso de estereotipos contra ella o por la tolerancia a la forma de violencia padecida. Contexto en el cual la mujer podrá demandar por el daño generado con ocasión a la revictimización como modalidad de la violencia institucional a través del juicio de responsabilidad del Estado por error judicial
description: The purpose of this thesis is to demonstrate that the gender perspective is part of the State's human rights obligations. For this reason, judges, regardless of their specialty, must apply the gender perspective when they hear a case involving some form of violence or discrimination against women. Therefore, if, contrary to expectations, the judicial operators decide not to use the gender perspective, it will cause re-victimization of the woman materialized in a judicial decision, either by the use of stereotypes against her or by the tolerance of the form of violence she has suffered. In this context, the woman may sue for the damage caused by revictimization as a form of institutional violence through the trial of State responsibility for judicial error.

description: We introduce a new model for the Carbon-12 nucleus and compute its lowest energy levels. Our model is inspired by previous work on the rigid body approximation in the $B=12$ sector of the Skyrme model. We go beyond this approximation and treat the nucleus as a deformable body, finding several new states. A restricted set of deformations is considered, leading to a configuration space $\mathcal{C}$ which has a graph-like structure. We use ideas from quantum graph theory in order to make sense of quantum mechanics on $\mathcal{C}$ even though it is not a manifold. This is a new approach to Skyrmion quantisation and the method presented in this paper could be applied to a variety of other problems.

The Impact of a Cost Rebate on the Economics of Solar Power in Canada
Creators: name: MacDougall, Hillary
Publisher: name: My University
Year: 2016

description: Incentives have been implemented in countries like Canada, the United States of America, and China, among others, to stimulate the deployment of solar power. Electricity from solar energy is one source of renewable energy that can reduce greenhouse gas emissions. Achieving a widespread adoption of solar projects depends on both the current subsidy for solar power and determining the ideal geographic location for solar insolation. This paper analyzes the impact of various systems cost incentives on the economics of residential solar projects in Western Canada. Eighteen cities across three provinces were analyzed for both photovoltaic and concentrated photovoltaic projects with start dates of 2016, 2018, and 2020. Additionally, this research looked at the impact of optimizing a PV system and how this impacts generated revenue. The internal rate of return (IRR) and discounted net present value (NPV) were calculated for each city under various cost incentive scenarios. The internal rate of return was then mapped for a visual estimate of the most economically viable location in which to install a solar system. This research finds that the internal rate of return for PV and CPV projects increases over time and shows the extent to which the application of additional systems cost incentives impacts this economic measurement. In order to make solar projects profitable to homeowners in Western Canada (IRR > 7%) the government needs to subsidize systems costs by 30%. The results also show that the value of the discount rate used has an impact on the net present value over time, and that the net present value generally increases over time, with the application of additional cost incentives. Moreover, the findings recommend deferring a solar project until the year 2020 where systems costs will decline and the price of electricity will rise, making solar projects an attractive investment.

description: Background: The aim of this paper is to share the methodological problems of an unsuccessful prospective single-arm feasibility trial conducted to evaluate the safety and feasibility of a 12-week progressive exercise intervention for adults undergoing neoadjuvant chemoradiotherapy for rectal cancer, as well as offer recommendations for future trials. Methods: The initial plan was to recruit adults diagnosed with rectal cancer and scheduled for neoadjuvant chemoradiotherapy over a 12-month period. The exercise intervention was to consist of supervised exercise sessions delivered three times per week by a trained exercise specialist. Feasibility (i.e., recruitment, adherence, and compliance rates) and safety (i.e., adverse events) were to be assessed throughout the trial, and patient-reported and physical health outcomes were to be assessed pre- and post-intervention. After 8 months of open recruitment, we had been unable to successfully enroll patients into our trial. We therefore modified our eligibility criteria to increase the number of patients that could be recruited into our trial, and in turn increase our recruitment rate. We also amended our recruitment procedures to ensure we could reach patients who were either awaiting treatment, receiving treatment, or had completed treatments in the past 5 years. In doing so, we added a research objective, namely to determine the optimal timing of conducting an exercise intervention with adults diagnosed with rectal cancer (i.e., during neoadjuvant treatment, after surgery, during adjuvant treatment, or post-treatment). Results: Many problems continued to hinder the progress of our trial, particularly the low recruitment rate and the failure to enroll the required sample size that would make our results reliable. Conclusion: This led us to conclude that our trial was not feasible and that it is advisable to consider some elements carefully (e.g., recruitment strategies, communication, and trial location) before designing and conducting future trials. If one or more of these elements still proves to be problematic, trial results risk being compromised and alternative approaches should be considered.

description: We introduce a methodology based on averaging similarity matrices with the aim of integrating the layers of a multiplex network into a single monoplex network. Multiplex networks are adopted for modelling a wide variety of real-world frameworks, such as multi-type relations in social, economic and biological structures. More specifically, multiplex networks are used when relations of different nature (layers) arise between a set of elements from a given population (nodes). A possible approach for investigating multiplex networks consists in aggregating the different layers in a single network (monoplex) which is a valid representation -- in some sense -- of all the layers. In order to obtain such an aggregated network, we propose a theoretical approach -- along with its practical implementation -- which stems on the concept of similarity matrix average. This methodology is finally applied to a multiplex similarity network of statistical journals, where the three considered layers express the similarity of the journals based on co-citations, common authors and common editors, respectively.

description: Government and private organizations are escalating their use of commercial off-the-shelf (COTS) and other pre-existing components in critical business systems. Attempts to exploit these components through use of traditional engineering approaches that involve defining requirements, formulating an architecture, and then searching for components that meet the specified requirements within the defined architecture have been disappointing. The Evolutionary Process for Integrating COTS-based systems (EPIC) redefines acquisition, management, and engineering practices to more effectively leverage the COTS marketplace and other sources of pre-existing components. This is accomplished through concurrent discovery and negotiation of diverse spheres of influence: user needs and business processes, applicable technology and components, the target architecture, and programmatic constraints. EPIC codifies these practices in a structured flow of key activities and artifacts. This alternative approach is a risk-based, disciplined, spiral-engineering approach which leverages the Rational Unified Process (RUP). This document is the first release of an overview of the EPIC framework along with its activities and artifacts. The first release of the full description of EPIC is found in the Software Engineering Institute technical report: Evolutionary Process for Integrating COTS-Based Systems (EPIC). These documents will be updated based on reader's comments and lessons learned from use of EPIC.

description: The magnitude of finite-size effects and Coulomb interactions in quantum Monte Carlo simulations of van der Waals interactions between weakly bonded benzene molecules are investigated. To that extent, two trial wave functions of the Slater-Jastrow and Backflow-Slater-Jastrow types are employed to calculate the energy-volume equation of state. We assess the impact of the backflow coordinate transformation on the non-local correlation energy. We found that the effect of finite-size errors in quantum Monte Carlo calculations on energy differences is particularly large and may even be more important than the employed trial wave function. Beside the cohesive energy, the singlet excitonic energy gap and the energy gap renormalization of crystalline benzene at different densities are computed.

description: Mobile applications increasingly are being used by first responders and soldiers to support their missions. These users operate in resource-constrained, edge environments characterized by dy-namic context, limited computing resources, intermittent network connectivity, and high levels of stress. In addition to efficient battery management, mobile applications operating in edge environments require efficient resource usage of onboard sensors to capture, store, and send data across networks that may be intermittent. The traditional method for building mobile applications is to use native software development kits (SDKs) on a particular mobile platform, such as An-droid or iOS. However, HTML5 has recently evolved to a stage where it supports many of the development features that native SDKs support. The advantages of using HTML5 not only in-clude cross-platform development and deployment, but also that mobile edge applications would not have to be deployed on mobile devices, potentially leading to an easier distribution and testing process because they simply run inside the web browser that already exists on the device. This technical note presents an analysis of the feasibility of using HTML5 for developing mobile edge applications, as well as the use of bridging frameworks for filling in gaps in HTML5 development features. This note also provides a discussion of the software architecture implications of HTML5 mobile application development. The work presented in this note is the result of an independent study in Carnegie Mellon University’s Master of Information Technology - Embedded Software Engineering (MSIT-ESE) program.

description: Since the outset of COVID-19, the pandemic has prompted immediate global efforts to sequence SARS-CoV-2, and over 450 000 complete genomes have been publicly deposited over the course of 12 months. Despite this, comparative nucleotide and amino acid sequence analyses often fall short in answering key questions in vaccine design. For example, the binding affinity between different ACE2 receptors and SARS-COV-2 spike protein cannot be fully explained by amino acid similarity at ACE2 contact sites because protein structure similarities are not fully reflected by amino acid sequence similarities. To comprehensively compare protein homology, secondary structure (SS) analysis is required. While protein structure is slow and difficult to obtain, SS predictions can be made rapidly, and a well-predicted SS structure may serve as a viable proxy to gain biological insight. Here we review algorithms and information used in predicting protein SS to highlight its potential application in pandemics research. We also showed examples of how SS predictions can be used to compare ACE2 proteins and to evaluate the zoonotic origins of viruses. As computational tools are much faster than wet-lab experiments, these applications can be important for research especially in times when quickly obtained biological insights can help in speeding up response to pandemics.

description: A search for heavy resonances decaying into a pair of $Z$ bosons leading to $\ell^+\ell^-\ell^+\ell^-$ and $\ell^+\ell^-ν\barν$ final states, where $\ell$ stands for either an electron or a muon, is presented. The search uses proton proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 36.1 fb$^{-1}$ collected with the ATLAS detector during 2015 and 2016 at the Large Hadron Collider. Different mass ranges for the hypothetical resonances are considered, depending on the final state and model. The different ranges span between 200 GeV and 2000 GeV. The results are interpreted as upper limits on the production cross section of a spin 0 or spin 2 resonance. The upper limits for the spin 0 resonance are translated to exclusion contours in the context of Type I and Type II two-Higgs-doublet models, while those for the spin 2 resonance are used to constrain the Randall Sundrum model with an extra dimension giving rise to spin 2 graviton excitations.

description: Objective: To evaluate the impact of a geriatric day hospital program on older adults' functional independence and on caregiver stress. Methods: We used a single group pre- and posttest design. The data were collected through chart reviews and follow-up phone calls. Outcomes included fear of falling, balance, functional exercise capacity (walking distance), and caregiver stress. Descriptive statistics were used for sociodemographic data, dependent t test for paired samples of normally distributed data, and the Wilcoxon signed-rank test for determining differences between nonnormally distributed data sets. Results: We found a statistically significant difference in pre (33.54) and post (27.47) mean rank scores for fear of falling (Z = -3.895, P < .001), pre (49.5) and post (59.42) scores for balance (Z = -8.725, P < .001), and pre (250.07 m) and post (291.20 m) for functional exercise capacity (P < .001). No statistically significant difference was found with respect to caregiver stress pre (22.05) and post (19.90) scores (Z = -0.422, P = .673). Discussion: Future research may consider approaching evaluative studies of a similar type using not only quantitative but also qualitative methods to obtain a more comprehensive understanding of older adults' functional ability and caregiver stress before and after participating in a geriatric day hospital program.

description: The recent discovery of gravitational waves from GW170817, associated with a short Gamma-Ray Burst (GRB) at a distance of $40$Mpc, has demonstrated that short GRBs can occur locally and at a reasonable rate. Furthermore, gravitational waves enable us to detect close by GRBs, even when we are observing at latitudes far from the jet's axis. We consider here Compton echoes, the scattered light from the prompt and afterglow emission. Compton echoes, an as yet undetected counterpart of GRBs, peak in X-rays and maintain a roughly constant flux for hundreds to thousands of years after the burst. Though too faint to be detected in typical cosmological GRBs, a fraction of close by bursts with a sufficiently large energy output in X-rays, and for which the surrounding medium is sufficiently dense, may indeed be observed in this way. The detection of a Compton echo could provide unique insight into the burst properties and the environment's density structure. In particular, it could potentially determine whether or not there was a successful jet that broke through the compact binary merger ejecta. We discuss here the properties and expectations from Compton echoes and suggest methods for detectability.

description: The SEI has been involved with the development and analysis of software process models for several years. As part of the ongoing process of technology evolution, a study has been undertaken to experimentally implement a set of proposed improvements to the process modeling techniques used by the SEI, and to evaluate the results of that experimentation. As a result of that study, a number of modifications to our techniques have been identified. These modifications enhance the support of software engineering concepts in the development and use of process models. This report describes the study and elaborates upon the advantages and disadvantages of the proposed technique improvements.
