title: Wind intensity affects fine root morphological traits with consequences for plant-soil feedback effects
Creators: name: Werger, Luise

description: Wind influences the development, architecture and morphology of plant roots and may modify subsequent interactions between plants and soil (plant–soil feedbacks—PSFs). However, information on wind effects on fine root morphology is scarce and the extent to which wind changes plant–soil interactions remains unclear. Therefore, we investigated the effects of two wind intensity levels by manipulating surrounding vegetation height in a grassland PSF field experiment. We grew four common plant species (two grasses and two non-leguminous forbs) with soil biota either previously conditioned by these or other species and tested the effect of wind on root:shoot ratio, fine root morphological traits as well as the outcome for PSFs. Wind intensity did not affect biomass allocation (i.e. root:shoot ratio) in any species. However, fine-root morphology of all species changed under high wind intensity. High wind intensity increased specific root length and surface area and decreased root tissue density, especially in the two grasses. Similarly, the direction of PSFs changed under high wind intensity in all four species, but differences in biomass production on the different soils between high and low wind intensity were marginal and most pronounced when comparing grasses with forbs. Because soils did not differ in plant-available nor total nutrient content, the results suggest that wind-induced changes in root morphology have the potential to influence plant–soil interactions. Linking wind-induced changes in fine-root morphology to effects on PSF improves our understanding of plant–soil interactions under changing environmental conditions.

description: Brain-Computer Interfaces (BCIs) allow direct neurological control of assistive technologies such as prosthetics, wheelchairs, and other devices. Because there are no complete, biological remedies for full neural-regeneration, there is a rising prevalence of such technologies in the world of rehabilitation. These devices also raise questions about how BCI-mediated actions may intersect with our current ways of understanding moral responsibility. How should we think about concepts such as blame when applied to BCI-mediated actions? Full video link below.

description: Inspired by the Turing mechanism for pattern formation, we propose a simple self-propelled particle model with short-ranged alignment and anti-alignment at larger distances. It is able to produce orientationally ordered states, periodic vortex patterns as well as meso-scale turbulence. The latter phase resembles observations in dense bacterial suspensions. The model allows a systematic derivation and analysis of a kinetic theory as well as hydrodynamic equations for density and momentum fields. A phase diagram with regions of such pattern formation as well as spatially homogeneous orientational order and disorder is obtained from a linear stability analysis of these continuum equations. Microscopic Langevin simulations of the self-propelled particle system are in agreement with these findings.

description: We estimate dark matter density for the Universe with a reheating temperature smaller than the mass of dark matter, assuming dark matter to be a weakly interacting massive particle. During the reheating process, an inflaton decays and releases high-energy particles, which are scattered inelastically by the thermal plasma and emit many particles. Dark matters are produced through these inelastic scattering processes and pair creation processes by high-energy particles. We properly take account of the Landau-Pomeranchuk-Migdal effect on inelastic processes and show that the resultant energy density of dark matter is much larger than that estimated in the literature and can be consistent with that observed when the mass of dark matter is larger than $O(100)$ GeV.

Zimbabwe’s Mental Genocide
Creators: name: Bhila, Takura
Publisher: name: figshare
Year: 2022
Subjects: Educational technology and computing

description: The easiest way to destroy generations and a nation is through depriving the youth their education. Education is a basic human right not a privilege as is the current case in Zimbabwe. The government of Zimbabwe of July 2018 – 2023 has decided to hide under covid 19 to deprive the innocent children their education. Schools and universities were closed in March 2020 to minimise covid 19 transmission. Little did we know that this was the opportune time for this government to kill the Zimbabwean children intellectually. The education system that was in intensive care, on oxygen, had the oxygen tanks switched off, to the government’s celebration. Teachers and learners were dispatched home indefinitely. While there were celebrations in the corridors of power that we have tamed (SARS-CoV-2) Covid 19 through schools’ closure, other countries upon closing schools started planning on how they were going to make education accessible during the covid 19 pandemic. The government of Zimbabwe was honeymooning abusing donated covid 19 funds. Teachers’ salaries were equalling US 35 from US 520 in 2018. Indirectly it was destroying and devaluing the once admired education system. Some schools changed ownership, from being community schools to private entities at the detriment of the working class child whose parents survived on US1 per day. Bearing the brunt are the children of the marginalised because there is no school anymore. The teachers have no salary. The children of the government officials are enrolled in elite private schools in and outside the country. The children of most of the population whom they coerce to vote for them are deprived of education. They are killing them so that their own children and grandchildren will succeed them in future in those same government and political offices they occupy today. It is at the backdrop of these stated facts that I argue that the government of Zimbabwe 2018-2023’s agenda is to suffocate the public education system in Zimbabwe to perpetuate poverty, anarchy, cronyism, despotism, and demagoguery. Data was generated qualitatively informed by the theory of Ubuntu. This theory is fit for the study because this is about human relationships. Interviews with teachers and document analysis focusing on speeches by ZANU (PF) and MDC political parties were data generation tools. Data was processed coded and conclusions were made.

Finite-Horizon Parameterizing Manifolds, and Applications to Suboptimal Control of Nonlinear Parabolic PDEs

description: This article proposes a new approach based on finite-horizon parameterizing manifolds (PMs) for the design of low-dimensional suboptimal controllers to optimal control problems of nonlinear partial differential equations (PDEs) of parabolic type. Given a finite horizon $[0,T]$ and a low-mode truncation of the PDE, a PM provides an approximate parameterization of the uncontrolled high modes by the controlled low ones so that the unexplained high-mode energy is reduced, in an $L^2$-sense, when this parameterization is applied. Analytic formulas of such PMs are derived by application of the method of pullback approximation of the high-modes (Chekroun, Liu, and Wang, 2013, http://arxiv.org/pdf/1310.3896v1.pdf). These formulas allow for an effective derivation of reduced ODE systems, aimed to model the evolution of the low-mode truncation of the controlled state variable, where the high-mode part is approximated by the PM function applied to the low modes. A priori error estimates between the resulting PM-based low-dimensional suboptimal controller $u_R^\ast$ and the optimal controller $u^*$ are derived. These estimates demonstrate that the closeness of $u_R^\ast$ to $u^*$ is mainly conditioned on two factors: (i) the parameterization defect of a given PM, associated respectively with $u_R^\ast$ and $u^*$; and (ii) the energy kept in the high modes of the PDE solution either driven by $u_R^\ast$ or $u^*$ itself. The practical performances of such PM-based suboptimal controllers are numerically assessed for various optimal control problems associated with a Burgers-type equation. The numerical results show that a PM-based reduced system allows for the design of suboptimal controllers with good performances provided that the associated parameterization defects and energy kept in the high modes are small enough, in agreement with the rigorous results.

description: Purpose: This paper aims to extend the traditional conceptualization of localization, which has largely focused on recruitment, by examining “employability” and “retention” as crucial determinants of localization success. Design/methodology/approach: Using survey data from local (Emirati) employees in private sector organizations in the United Arab Emirates (UAE), the authors develop a holistic model of localization and test the relationships between stereotypes, organizational socialization, employability and retention outcomes, using Smart-PLS. Findings: Among the main findings are the significant influence of stereotypes on organizational socialization (OS) experiences of Emirati employees, with a negative relationship between “work ethics stereotypes” and perceptions of OS experiences. Strong evidence is also found for the indirect effects of OS experiences on retention of Emirati employees, mediated by employability. Research limitations/implications: This study contributes to the literature on localization by examining the relationships between key variables not examined together in previous research. In terms of limitations, the cross-sectional nature of the study prevents the identification of direction of causality among these relationships. Since employee integration, as part of localization efforts, is a gradual process, future research should include longitudinal studies. Practical implications: Employability has emerged as a significant challenge for organizations and governments working to implement successful localization initiatives. This study’s findings highlight several opportunities for organizational and governmental policy interventions to support successful localization. Originality/value: The authors’ holistic model extends localization literature by providing evidence for the role of stereotypes and employability as key constructs to be examined along with OS experiences and retention.

description: We study the transverse single-spin asymmetry for single-hadron production in proton-proton collisions within the framework of collinear twist-3 factorization in Quantum Chromodynamics. By taking into account the contribution due to parton fragmentation we obtain a very good description of all high transverse-momentum data for neutral and charged pion production from the Relativistic Heavy Ion Collider. Our study may provide the crucial step towards a final solution to the longstanding problem of what causes transverse single-spin asymmetries in hadronic collisions within Quantum Chromodynamics. We show for the first time that it is possible to simultaneously describe spin/azimuthal asymmetries in proton-proton collisions, semi-inclusive deep-inelastic scattering, and electron-positron annihilation by using collinear twist-3 factorization in the first process along with transverse momentum dependent functions extracted from the latter two reactions.

description: This paper analyzes the complicated nature of Dharma as it relates to women in Hinduism. We are given a contrasting account of women in Hindu texts, in the legal and political treatises we see classical gender schemas of Patriarchy and female subordination. In the narrative works however, we see examples of women actively challenging men using the tools traditionally associated with masculinity (reason, argumentation, religious purity etc.). This paper attempts to navigate this discrepancy and explain how the contradictory representation of women can actually offer insight into the way gender was perceived and expressed in ancient India.
A reimagined approach to professional development for Irish mathematics teachers
Creators: name: White, Jillian
Publisher: name: University of Limerick
Year: 2022
Subjects: Education

description: Upon completion of their initial teacher education programmes, professional development opportunities are often the only form of formal education teachers experience in relation to how they teach. When conducted effectively, professional development has the potential to challenge teachers and assist them to develop new skills. In an ever-changing world, teachers need to adapt how they teach to adequately prepare their students for further education, work, and life in general. The aim of this study was to design an approach to professional development for Irish mathematics teachers that could support their career-long development and assist them to better incorporate the changes to teaching and learning evident in recent national mathematics curriculum reforms. Based on the tenets of complexity theory, this project aimed to gain insights into four major influences on Irish mathematics teachers’ professional development and use these insights to suggest a reimagined approach to professional development for Irish mathematics teachers. The four perspectives were: (1) the theoretical and experimental literature on best practice regarding mathematics teachers’ professional development; (2) the experiences of education systems globally regarding the professional development of mathematics teachers; (3) the views of current Irish mathematics teachers; and (4) the policy documents of the major stakeholders influencing teacher professional development in Ireland. The suggestions made by this research project include the need for a structure of professional development to be designed so that all mathematics teachers in Ireland have regular access to converse and collaborate with colleagues. A structure of learning communities through which mathematics teachers can explore an area of interest with other mathematics teachers was the recommended approach. This research also makes suggestions on: how teachers could be provided with the time to engage in these communities during already contracted hours; how communities could network with one another and access the expertise of knowledgeable others using an existing Irish online collaboration platform; who could provide the necessary administration support regarding these communities; what resources communities will need access to and who should provide these resources; and what data should be collected by and for these communities and what use this data could serve.
A geometric approach to the distribution of quantum states in bipartite physical systems
Creators: name: Batle, J.
Publisher: name: arXiv
Year: 2013
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Any set of pure states living in an given Hilbert space possesses a natural and unique metric --the Haar measure-- on the group $U(N)$ of unitary matrices. However, there is no specific measure induced on the set of eigenvalues $Δ$ of any density matrix $ρ$. Therefore, a general approach to the global properties of mixed states depends on the specific metric defined on $Δ$. In the present work we shall employ a simple measure on $Δ$ that has the advantage of possessing a clear geometric visualization whenever discussing how arbitrary states are distributed according to some measure of mixedness. The degree of mixture will be that of the participation ratio $R=1/Tr(ρ^2)$ and the concomitant maximum eigenvalue $λ_m$. The cases studied will be the qubit-qubit system and the qubit-qutrit system, whereas some discussion will be made on higher-dimensional bipartite cases in both the $R$-domain and the $λ_m$-domain.

description: How should businesses best choose foreign partners as they seek to internationalise? We use reputation theory to examine this question. Building reputation is a key aim on the European Business School scene, and this article starts by using more than 2,000 articles written by European academics in top quality journals to update the LRP research reputation rankings of European Schools. We then look at the way international research collaboration takes place, and find that alliances between schools are far from random. It seems that academics from US and European schools are strongly attracted to form alliances with one another, and the choice process appears to be consistent with reputation theory that suggests US schools seek out the most reputable foreign partners. Moreover, the "charmed circle" of high-reputation partners appears to be defined on a country-to-country basis rather than from a whole-Europe perspective. The lessons for managers in internationalising industries are that international alliance choice must include a reputation perspective, with great care being paid to the exact nature of the foreign partner's achievements. © 2002 Elsevier Science Ltd.

description: Purpose: While the literature on migration highlights the reshaping of host and immigrant population in countries, there is a paucity of research in marketing investigating the evolving dynamics for acculturation. The purpose of this study is to further the understanding of the emerging phenomenon of acculturation and identity negotiation. Design/methodology/approach: Three experiments examined situational ethnicity, self-construal and identity negotiation in home and host culture work and social settings. Study 1 and Study 2 were conducted in the United Kingdom (UK), where the host country is the majority population. Study 3 was conducted in the United Arab Emirates (UAE), where the host country is the minority population. Study 4 utilized qualitative interviews in both countries. Findings: Results from all four studies show that ethnic consumers deploy “indifference” as an identity negotiation mechanism when the host society is the majority population (UK) and when the host society has the minority population (UAE). Originality/value: The authors offer new insights into identity negotiation by ethnic consumers when the host society is the majority population as well as the minority population. “Indifference”, i.e. preferring to neither fit in nor stand out as an identity negotiation mechanism, is deployed in work and social settings of home and host societies. The authors also advance the existing literature on acculturation by examining whether independent and interdependent self-construal influence identity negotiation.

description: This paper examines load profiles of three commercial parking garages and, in this context, created individual load profiles for them. A considerable proportion of the operating costs of parking garages is accounted for by energy and maintenance costs. The lighting systems and the ventilation system are the main cost drivers. The aim is to use these load profiles to estimate energy consumption and its structure over the course of the day, week and year, as well as to identify efficiency measures and potential savings with regard to operational energy costs. The necessity of such individual load profiles results on the one hand from the lack of current representative commercial profiles for this industry, and on the other hand from the heterogeneity of the individual buildings. Here it becomes clear that the construction and energy concept of the parking garages have a great influence on the consumption patterns. Therefore, parking garages were equipped with a detailed metering infrastructure in the project ”SmartPark” funded by the BMWK.

description: We study the alignment of the vacuum in gauge theories with $N_f$ Dirac fermions transforming according to a complex representation of the gauge group. The alignment of the vacuum is produced by adding a small mass perturbation to the theory. We study in detail the $N_f=2,3$ and $4$ case. For $N_f=2$ and $N_f=3$ we reproduce earlier known results including the Dashen phase with spontaneous violation of the combined charge conjugation and parity symmetry, CP. For $N_f=4$ we find regions with and without spontaneous CP violation. We then generalize to an arbitrary number of flavors. Here it is shown that at the point where $N_f-1$ flavors are degenerate with positive mass $m>0$ and the mass of the $N_f$'th flavor becomes negative and equal to $-m$ CP breaks spontaneously.

description: We find a solution to $4D$ Einstein-Maxwell theory coupled to a massless dilaton field describing a Melvin magnetic field in an expanding universe with 'stiff matter' equation of state parameter $w=+1$. As the universe expands, magnetic flux becomes more concentrated around the symmetry axis for dilaton coupling $a<1/\sqrt{3}$ and more dispersed for $a>1/\sqrt{3}$. An electric field circulates around the symmetry axis in the direction determined by Lenz's law. For $a=0$ the magnetic flux through a disk of fixed comoving radius is proportional to the proper area of the disk. This result disagrees with the usual expectation based on a test magnetic field that this flux should be constant, and we show why this difference arises. We also find a Melvin solution in an accelerating universe with $w=-7/9$ for a dilaton field with a certain exponential potential. Our main tools are simple manipulations in $5D$ Kaluza-Klein theory and related solution generating techniques. We also discuss a number of directions for possible extensions of this work.

Environmental Political Theory

description: The need to lower emissions to prevent catastrophic climate change is clear, but the political path to achieve such a future is unclear. The emerging field of environmental political theory is divided on the best form of governance to successfully mitigate the climate crisis. Liberal democracies around the world are dealing with climate change with various levels of success, while authoritarian regimes are providing a potential alternative path. This paper utilizes three environmental political frameworks that fall across the spectrum of theory: "Too Hot to Handle? The Democratic Challenge of Climate Change" by Rebecca Willis, "The Climate Change Challenge and the Failure of Democracy" by David Shearman and Joseph Wayne, and "Climate Leviathan: A Political Theory for Our Future by Geoff Mann and Joel Wainwright." To understand the strengths and weaknesses of each theory as well as the field as a whole, Denmark, China, and the United States are used to see how the theories perform in the real world and extrapolate issues that are hindering the efficacy of environmental political theory in securing positive sustainable governance. This analysis concludes with three main findings: environmental theory is too broad in its scope, effective frameworks must focus on the domestic political level, and new environmental political theories should work to provide specific guidance and policy reforms to reach its end goal.

description: Biotechnology companies can access financial and management resources through venture capitalist (VC) firms. An analysis of 1,490 VC investments shows that country-of-origin (CO) of biotech companies has an effect on the participation by VC firms in various biotech subsectors. Specifically, it is found that US biotech companies tend to have higher amount received per VC firm, greater number of VC firms investing in them and greater biotech investment experience of the investing VC firms. Asia-Pacific biotech companies have consistently less VC firms investing in them and these investing VC firms tend to have less biotech investment experience. VC firms with greater biotech investment experience are also investing in European biotech companies more than those from the Americas less US. CO also correlates with outcomes in the four of the six key biotech subsectors studied. These findings suggest a strong CO effect of VC investment in biotech companies.
Death is Not the End: The Role of Reactive Oxygen Species in Driving Apoptosis-induced Proliferation
Creators: name: Fogarty, Caitlin
Publisher: name: University of Massachusetts Medical School

description: Apoptosis-induced proliferation (AiP) is a compensatory mechanism to maintain tissue size and morphology following unexpected cell loss during normal development, and may also be a contributing factor to cancer growth and drug resistance. In apoptotic cells, caspase-initiated signaling cascades lead to the downstream production of mitogenic factors and the proliferation of neighboring surviving cells. In epithelial Drosophila tissues, the Caspase-9 homolog Dronc drives AiP via activation of Jun N-terminal kinase (JNK); however, the specific mechanisms of JNK activation remain unknown. Using a model of sustained AiP that produces a hyperplastic phenotype in Drosophila eye and head tissue, I have found that caspase-induced activation of JNK during AiP depends on extracellular reactive oxygen species (ROS) generated by the NADPH oxidase Duox. I found these ROS are produced early in the death-regeneration process by undifferentiated epithelial cells that have initiated the apoptotic cascade. I also found that reduction of these ROS by mis-expression of extracellular catalases was sufficient to reduce the frequency of overgrowth associated with our model of AiP. I further observed that extracellular ROS attract and activate Drosophila macrophages (hemocytes), which may in turn trigger JNK activity in epithelial cells by signaling through the TNF receptor Grindelwald. We propose that signaling back and forth between epithelial cells and hemocytes by extracellular ROS and Grindelwald drives compensatory proliferation within the epithelium, and that in cases of persistent signaling, such as in our sustained model of AiP, hemocytes play a tumor promoting role, driving overgrowth.

description: Στην παρούσα διπλωματική εργασία πραγματοποιείται συγκριτική τεχνο-οικονομική μελέτη διαφόρων μεθόδων ψύξης και θέρμανσης μιας νεόκτιστης κατοικίας στην περιοχή των Χανίων, με σκοπό την εύρεση της πιο συμφέρουσας λύσης.
    Η σημαντικότητά της έγκειται στο ότι σε κάθε νεόκτιστη κατοικία θα πρέπει να έχει πραγματοποιηθεί ενεργειακή μελέτη δεδομένου ότι στις μέρες μας αυτό δεν αποτελεί είδος πολυτελείας αλλά κάτι απόλυτα αναγκαίο που άπτεται της ποιότητας ζωής μας. Επομένως, είναι σημαντικό να γνωρίζει ο καταναλωτής την πιο συμφέρουσα για αυτόν λύση και να μην εστιάζει στο κόστος της αρχικής επένδυσης. Ως προς τα αναμενόμενα αποτελέσματα, ο στόχος είναι να διαφανεί ποιος από τους προς μελέτη συνδυασμούς είναι πιο συμφέρων και υπερτερεί των υπολοίπων.
    Οι υπολογισμοί των ψυκτικών και θερμικών φορτίων πραγματοποιούνται σύμφωνα με τα πρότυπα που ορίζουν οι κανονισμοί του Κ.ΕΝ.Α.Κ και η μεταξύ τους σύγκριση  υλοποιείται με την μέθοδο της Ετήσιας Αξίας. Tα δεδομένα που απαιτούνται είναι το αρχικό κόστος της επένδυσης, καθώς επίσης και το κόστος ενέργειας για την τρέχουσα περίοδο της μελέτης ή της εγκατάστασης.
    Αρχικά, παρατίθεται η μεθοδολογία που θα εφαρμοστεί για τον υπολογισμό των θερμικών απωλειών και των ψυκτικών φορτίων, καθώς και τα αντίστοιχα αποτελέσματα. Ακολούθως, αναπτύσσεται η αρχή λειτουργίας του καθενός από τους τρείς μηχανολογικούς εξοπλισμούς. Στη συνέχεια, επιλέγεται ο κατάλληλος εξοπλισμός για την κάλυψη των ενεργειακών αναγκών τόσο για την θέρμανση όσο και για την ψύξη και υπολογίζεται το ετήσιο κόστος τους. Τέλος, εφαρμόζεται η μέθοδος της ετήσιας αξίας και εξάγονται τα συμπεράσματα.

description: We point out a novel possible mechanism by which the electroweak hierarchy problem can be avoided in the (effective) quantum field theory. Assuming the existence of a UV complete underlying fundamental theory and treating the cutoff scale $Λ$ of the effective field theory as a real physical scale we argue that the hierarchy problem would be solved if the coefficient in front of quadratic divergences vanished for some choice of $Λ$, and if the effective theory mass parameters fixed at $Λ$ by the fundamental theory were hierarchically smaller than $Λ$ itself. While this mechanism most probably cannot work in the Standard Model if the scale $Λ$ is to be close to the Planck scale, we show that it can work in a minimal extension (Conformal Standard Model) proposed recently for a different implementation of soft conformal symmetry breaking.

description: Using methods based on conformal field theory, we construct model wave functions on a torus with arbitrary flat metric for all chiral states in the abelian quantum Hall hierarchy. These functions have no variational parameters, and they transform under the modular group in the same way as the multicomponent generalizations of the Laughlin wave functions. Assuming the absence of Berry phases upon adiabatic variations of the modular parameter $τ$, we calculate the quantum Hall viscosity and find it to be in agreement with the formula, given by Read, which relates the viscosity to the average orbital spin of the electrons. For the filling factor $ν=2/5$ Jain state, which is at the second level in the hierarchy, we compare our model wave function with the numerically obtained ground state of the Coulomb interaction Hamiltonian in the lowest Landau level, and find very good agreement in a large region of the complex $τ$-plane. For the same example, we also numerically compute the Hall viscosity and find good agreement with the analytical result for both the model wave function and the numerically obtained Coulomb wave function. We argue that this supports the notion of a generalized plasma analogy that would ensure that wave functions obtained using the conformal field theory methods do not acquire Berry phases upon adiabatic evolution.
MACHINE LEARNING FOR RESILIENT AND SUSTAINABLE ENERGY SYSTEMS UNDER CLIMATE CHANGE

description: Climate change is recognized as one of the most significant challenge of the 21st century. Anthropogenic activities have led to a substantial increase in greenhouse gases (GHGs) since the Industrial Revolution, with the energy sector being one the biggest contributors globally. The energy sector is now facing unique challenges not only due to decarbonization goals but also due to increased risks of climate extremes under climate change. This dissertation focuses on leveraging machine learning, specifically utilizing unstructured data such as images, to address many of the unprecedented challenges faced by the energy systems. The dissertation begins (Chapter 1) by providing an overview of the risks posed by climate change to modern energy systems. It then explains how machine learning applications can help with addressing these risks. By harnessing the power of machine learning and unstructured data, this research aims to contribute to the development of more resilient and sustainable energy systems, as described briefly below. Accurate forecasting of generation is essential for mitigating the risks associated with the increased penetration of intermittent and non-dispatchable variable renewable energy (VRE). In Chapters 2 and 3, deep learning techniques are proposed to predict solar irradiance, a crucial factor in solar energy generation, in order to address the uncertainty inherent in solar energy. Specifically, Chapter 2 introduces a cost-efficient fully exogenous solar irradiance forecasting model that effectively incorporates atmospheric cloud dynamics using satellite imagery. Building upon the work of Chapter 2, Chapter 3 extends the model to a fully probabilistic framework that not only forecasts the future point value of irradiance but also quantifies the uncertainty of the prediction. This is particularly important in the context of energy systems, as it relates to high-risk decision making.While the energy system is a major contributor to GHG emissions, it is also vulnerable to climate change risks. Given the essential role of energy systems infrastructure in modern society, ensuring reliable and sustainable operations is of utmost importance. However, our understanding of reliability analysis in electricity transmission networks is limited due to the lack of access to large-scale transmission network topology datasets. Previous research has mostly relied on proxy or synthetic datasets. Chapter 4 addresses this research gap by proposing a novel deep learning-based object detection method that utilizes satellite images to construct a comprehensive large-scale transmission network dataset.

description: In this paper, we study static vacuum solutions of quantum gravity at a fixed Lifshitz point in (2+1) dimensions, and present all the diagonal solutions in closed forms in the infrared limit. The exact solutions represent spacetimes with very rich structures: they can represent generalized BTZ black holes, Lifshitz space-times or Lifshitz solitons, in which the spacetimes are free of any kind of space-time singularities, depending on the choices of the free parameters of the solutions. We also find several classes of exact static non-diagonal solutions, which represent similar space-time structures as those given in the diagonal case. The relevance of these solutions to the non-relativistic Lifshitz-type gauge/gravity duality is discussed.
