Moreover, if the Dixmier (or minimal) angle between $Ran(S)$ and $Ker(T) \cap [Ker(T) \cap Ran(S)]^{\perp}$ is positive and $ \bar{Ker(S^*)+Ran(T^*)} $ is an orthogonal summand then $TS$ has closed range.

description: A two-dimensional electron gas exposed to a tilted magnetic field is considered with the Rashba spin-orbit interaction and the Zeeman effect. An exact solution for the eigenvalues were obtained assuming that two opposite spin states of adjacent Landau levels have equal probability. No crossings between adjacent eigenenergies were observed unlike in the perpendicular-magnetic-field case. The absence of crossings lead to quenched beating structures in the oscillations of the density of states (DOS). Persistent spin-splittings were observed at the weak magnetic field region. The splittings, however, can be effectively screened by an increased Landau level broadening. The results shed light on how spins can be controlled through the Rashba interaction strength, the disorder-related broadening and the magnetic field tilt angle.

description: We discuss SU(5) Grand Unified Theories in the context of orientifold compactifications. Specifically, we investigate two and three D-brane stack realizations of the Georgi-Glashow and the flipped SU(5) model and analyze them with respect to their Yukawa couplings. As pointed out in arXiv:0909.0271 the most economical Georgi-Glashow realization based on two stacks generically suffers from a disastrous large proton decay rate. We show that allowing for an additional U(1) D-brane stack this as well as other phenomenological problems can be resolved. We exemplify with globally consistent Georgi-Glashow models based on RCFT that these D-brane quivers can be indeed embedded in a global setting. These globally consistent realizations admit rigid O(1) instantons inducing the perturbatively missing coupling 10105^H. Finally we show that flipped SU(5) D-brane realizations even with multiple U(1) D-brane stacks are plagued by severe phenomenological drawbacks which generically cannot be overcome.

description: A general electroweak scale $Z'$ is applied in a supersymmetric SU(6)$\timesSU(2)_h$ grand unification model, to have a $\Z_6$ for the hexality. We briefly show that there cannot exist any baryonic U(1)$'_B$ in any subgroup of E$_6$. Any effect that requires sizable $Z'$ couplings to quarks like the reported Wjj anomaly of CDF, if observed, implies a substantial $Z'$ coupling to leptons or Higgs doublets. The kinetic mixing considered in a supersymmetric model from E$_6$ is restricted by the gauge coupling unification and neutrino mixing. The mass of $Z'$ is strongly constrained by the electroweak $ρ_0$ parameter. We conclude that $Z'$ mass much above 10 TeV is favored by considering the neutrino mixing and proton decay constraint in supersymmetric models. In this sense, the CDF $Wjj$ anomaly cannot be fitted to any electroweak model descending from E$_6$. Furthermore, if $Z'$ is found at several hundred GeV, any grand unification group embedded in E$_6$ such as SU(6)$\times$SU(2), SO(10), SU(5)$\times$U(1), SU(5), SU(4)$\times$SU(4), and SU(3)$^3$, needs fine-tuned gauge couplings. We also discuss the U(1)$'$ effect on the tree level mass of the lightest MSSM Higgs boson.

description: The Indian Ayurvedic physicians knew the concept of inflammation dating back to 1500 BC. The continuous progress in the immunology of inflammation has explained its undiscovered mechanisms. For example, the discovery of Toll-like receptor 4 (TLR4) in humans (1997) has revolutionized the field of infection biology and innate immunity. The laboratory mice have shown twelve TLRs and express TLR10 (CD290) as a disrupted pseudogene, and humans have ten functional TLRs. Now, it is well established that TLRs play a significant role in different infectious and inflammatory diseases. Skin inflammation and other associated inflammatory diseases, including atopic dermatitis (AD), acne vulgaris, and psoriasis, along with many skin cancers are major health problems all over the world. The continuous development in the immunopathogenesis of inflammatory skin diseases has opened the window of opportunity for TLRs in studying their role. Hence, the manuscript explores the role of different TLRs in the pathogenesis of skin inflammation and associated inflammatory diseases. The article starts with the concept of inflammation, its origin, and the impact of TLRs discovery on infection and inflammation biology. The subsequent section describes the burden of skin-associated inflammatory diseases worldwide and the effect of the geographical habitat of people affecting it. The third section explains skin as an immune organ and explains the expression of different TLRs on different skin cells, including keratinocytes, Langerhans cells (LCs), skin fibroblasts, and melanocytes. The fourth section describes the impact of TLRs on these cells in different skin-inflammatory conditions, including acne vulgaris, AD, psoriasis, and skin cancers. The article also discusses the use of different TLR-based therapeutic approaches as specific to these inflammatory skin diseases.

Meso-scale structures in social contagion and graph neural networks
Creators: name: Eslami, Roozbeh
Publisher: name: University of British Columbia
Year: 2022

description: Networks have been used to model complex real-world systems where pairwise interactions between objects are captured by the edges of the network. Recently, there has been a growing interest in meso-scale network structures. These structures go beyond pair-wise interactions and include higher-order sets of nodes such as, cliques, simplexes, hyperedges, etc. Interesting phenomena have been observed when higher-order interaction is taken into account. In this thesis, we studied the impact of meso-scale structures on the behavior of social contagion systems and machine learning models for network data. Using intersection models of graphs, we proposed a superimposition model of networks to better understand the behavior of social contagion process where meso-scale interactions may play a significant role. We investigated different higher-order propagation mechanisms and the nature of phase transitions in the outcome of the spreading processes. Moreover, we did extensive simulation to validate our assumptions. We also developed a Python package for modeling and simulating spreading mechanisms on standard and higher-order graphs. Furthermore, we investigated the effects of meso-scale structures on graph neural networks and our main goal was to investigate whether it is beneficial to incorporate information from the network community structure into the deep learning model. We investigated different ways of incorporating community structure information in the deep learning model and provided a comparison to other commonly used models on a variety of datasets.

Relativistic and Recoil Corrections to Vacuum polarization in muonic systems: Three--photon exchange, gauge invariance and numerical values

Publisher: name: arXiv
Year: 2024
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: For an accurate theoretical description of muonic bound systems, it is crucial to consistently treat relativistic and recoil corrections to vacuum polarization. The one-loop vacuum-polarization effect is by far the dominant quantum electrodynamic (QED) energy correction for bound muons, being of order $α(Zα)^2 m_r$, where $α$ is the fine-structure constant, $Z$ is the nuclear charge number, and $m_r$ is the reduced mass. Gauge invariance of the relativistic and recoil corrections to vacuum polarization of order $α(Zα)^4 m_r$ is investigated with respect to nonretarded and standard, renormalized variants of Coulomb gauge. The invariance is shown after including three-photon exchange diagrams. Our derivation is based on an adapted form of Nonrelativistic Quantum Electrodynamics for bound muon systems (NRQED$_μ$), which is a version of NRQED where the hard scale is set at the muon mass instead of the electron mass. Updated values for the gauge-independent corrections for one-muon ions with nuclear charge numbers $Z = 1,2,6$ are presented.

description: Multi-dimensional quantum walks usually require large coin spaces. Here we show that the non-localized case of the spatial density probability of the two-dimensional Grover walk can be obtained using only a two-dimensional coin space and a quantum walk in alternate directions. We present a formal proof of this correspondence and analyze the behavior of the coin-position entanglement as well as the x-y spatial entanglement in our scheme with respect to the Grover one. We show that our experimentally simpler scheme allows to entangle the two orthogonal directions of the walk more efficiently.

title: The vocabulary challenge of the English Language GCSE Exam and the implications for adolescent reading experience
Creators: name: Jennings, Beverley Judith
Publisher: name: University of Reading
Year: 2025

description: A new English language GCSE exam in England has put an increased focus on 
adolescents’ comprehension of unseen literary texts, from all three of the 19th, 20th and 21st
centuries. Since reading experience is a strong predictor of successful reading 
comprehension, it is important to know whether what adolescents read prepares them for this 
new exam. Any findings related to this particular exam could also have broader implications 
for other assessment jurisdictions and for theory. This PhD project focuses on: 1) the 
vocabulary challenge presented by the new exam texts; 2) the type of reading material that 
provides experience with this vocabulary; and 3) the actual reading experience of 
adolescents, including the vocabulary they encounter. First, a corpus of exam texts was 
created and analysed to examine typical vocabulary (Paper 1). Next, a survey reported 
respondents’ attainment in the English language GCSE exam and their reading experience 
(Paper 2). Finally, two further corpora, created from samples of students’ independent and 
curriculum reading materials, were analysed (Paper 3). The keywords in the exam texts were 
found to be typically low frequency and most likely to be encountered in older, literary texts. 
The reading survey showed that students who gained high grades also had more exposure to 
classic authors. The final corpus analysis showed that students’ independent reading for 
pleasure was a better match for the exam texts than their curriculum reading, although the 
vocabulary in the curriculum reading was more challenging. This study contributes new 
primary data in the three new corpora and in the data on adolescent reading habits from the 
survey. It shows that reading experience can be analysed and explored through the use of 
corpus linguistics and through a genre-specific ART. Finally, a potential influence of 
assessment content on curriculum choices and on reading practices is identified.

description: Surface diffusion of interacting adsorbates is here analyzed within the context of two fundamental phenomena of quantum dynamics, namely the quantum Zeno effect and the anti-Zeno effect. The physical implications of these effects are introduced here in a rather simple and general manner within the framework of non-selective measurements and for two (surface) temperature regimes: high and very low (including zero temperature). The quantum intermediate scattering function describing the adsorbate diffusion process is then evaluated for flat surfaces, since it is fully analytical in this case. Finally, a generalization to corrugated surfaces is also discussed. In this regard, it is found that, considering a Markovian framework and high surface temperatures, the anti-Zeno effect has already been observed, though not recognized as such.

Thermally assisted spin transfer torque switching in synthetic free layers

description: We studied the magnetization reversal rates of thermally assisted spin transfer torque switching in a ferromagnetically coupled synthetic free layer theoretically. By solving the Fokker-Planck equation, we obtained the analytical expression of the switching probability for both the weak and the strong coupling limit. We found that the thermal stability is proportional to Delta_{0}(1-I/I_{c})^{2}, not Delta_{0}(1-I/I_{c}) argued by Koch et al. [Phys. Rev. Lett. 92, 088302 (2004)], where I and I_{c} are the electric current and the critical current of spin transfer torque switching at absolute zero temperature. The difference in the exponent of (1-I/I_{c}) leads to a significant underestimation of the thermal stability Delta_{0}. We also found that fast switching is achieved by choosing the appropriate direction of the applied field.

In particular, we find that is highly non-monotonic function of $λ$ along the generic direction $λ_1\simλ_2 = λ$ when the system size $L$ is bounded between the shorter and longer correlation lengths characterizing the MCP: $1/|λ|^{ν_1}\ll L\ll 1/|λ|^{ν_2}$, where $ν_1

description: Microbially Induced Calcium Carbonate Precipitation (MICP) is an eco-friendly technique that enhances soil mechanical properties using urease-producing microorganisms, especially Sporosarcina pasteurii. However, field trials often yield suboptimal results due to the presence of indigenous soil microbes. To evaluate their impact, bacteria from natural soil were classified into two groups: low-ureolysis and high-ureolysis. These were combined with S. pasteurii in experiments using microfluidic chips and sand columns. The analysis covered bacterial populations, urease activity, pH changes, calcium carbonate crystal metrics, and unconfined compressive strength (UCS). Results indicated that mixing low-ureolysis bacteria with S. pasteurii resulted in a 74-84% reduction in bacterial activity and a 60% decrease in chemical conversion rate, leading to a 60% drop in UCS. In contrast, combining high-ureolysis bacteria with S. pasteurii reduced bacterial activity by 49-54%, which was less than the 64% reduction seen with S. pasteurii alone. This combination improved calcium carbonate conversion rates by 9% to 45% and slightly enhanced UCS.The study highlights the distinct effects of low-ureolysis and high-ureolysis bacteria on MICP efficiency, particularly regarding their influence on pH. Low-ureolysis bacteria decrease pH, while high-ureolysis bacteria increase it. Maintaining high bacterial activity and precipitation rates is crucially dependent on pH levels. Future strategies could focus on reducing the presence of low-ureolysis bacteria or sustaining higher pH levels to enhance MICP effectiveness in field applications.

Periodontal disease epidemiology : assessment of untreated periodontitis and accuracy of partial mouth recording protocols
Creators: name: Alawaji, Yasmine
Publisher: name: University of British Columbia
Year: 2022

description: The current thesis includes three projects that covered several aspects of periodontitis epidemiology. The first project focused on studying the prevalence, extent, and associations with untreated periodontitis. A purposive sample of 431 subjects never treated for periodontal conditions was clinically examined at screening dental school clinics. Background data were collected using questionnaires. The prevalence, extent, and associations with untreated periodontitis were evaluated. Our findings showed that the prevalence and extent of untreated periodontitis were high in untreated subjects. Significant exposures associated with untreated periodontitis included age ≥35 years, male sex, lower education, lower income, uncontrolled diabetes mellitus, current cigarette smoking, and lower perceived stress. The second thesis project compared the performance of partial-mouth recording protocols (PRP) with the full-mouth recording protocol (FRP) to estimate the prevalence, extent, and associations of untreated periodontitis. Three PRPs were selected: full-mouth at the mesiobuccal and distolingual sites [(FM)MB-DL], half-mouth at mesiobuccal and distolingual [(HM)MB-DL] and random-half-mouth (RHM) protocol. The accuracy of PRPs was compared with that of FRP by calculating the sensitivity, negative predictive value, and absolute bias. Our findings showed that PRPs had the highest overall accuracy in estimating the untreated periodontitis prevalence, extent, and associations were the (FM)MB-DL and RHM. The third project focused on studying the accuracy of using PRPs in estimating the prevalence, extent, severity, and associations of periodontitis for population-based studies using a systematic review and meta-analyses. A systematic literature search was conducted to retrieve the studies that examined the accuracy of PRP toward estimating the periodontitis prevalence, its extent, severity, and its associations. Data selection, extraction, synthesis, and meta-analyses were performed for 14 studies that matched the eligibility criteria. Our findings include the following: the PRPs that had the highest overall accuracy in studying the periodontitis prevalence, its extent and severity were the (FM)MB-B-DL, (FM)MB-DL, full-mouth at Mesiobuccal-Midbuccal-Distobuccal [(FM)MB-B-DB] sites, (FM)MB-DB, a total of 84 sites using random site selection method, and RHM. Based on a limited number of studies, estimating the associations with periodontitis using PRPs resulted in marginal bias.

title:  Understanding the Association Between Social Networks, College Student Alcohol Use, and Protective Behavioral Strategy Use and Beliefs
Creators: name: Colangelo, Melissa Roberts
Publisher: name: Old Dominion University Libraries
Year: 2020

description: Heavy drinking and alcohol-related problems are a growing concern for American college students (Jun, Agley, Huang, & Gassman, 2015). Social networks, or peer groups, have demonstrated predictive associations with college students’ alcohol outcomes (Neighbors, Lee, Lewis, Fossos, & Larimer, 2007). Protective behavioral strategies (PBS), defined as behaviors used to reduce negative alcohol-related consequences, are often assessed as a mechanism of change and predictor of alcohol outcomes (Martens, Taylor, Damann, Page, Mowry, & Cimini, 2004). Still, the association between social networks’ and college students’ own PBS use has yet to be explored. The current study was designed to address this gap in the literature to better understand the association between social network members’ drinking-related behaviors and college students’ alcohol use. Participants (n = 566) were undergraduates who completed the web-based survey for research credit in participating psychology classes. Students were asked about their alcohol use, PBS use, and beliefs about PBS, as well as the perceived alcohol use and PBS use of five members of their social networks. Results show that a larger proportion of social network members reported as heavy drinkers was a significant predictor of higher alcohol quantity, higher peak alcohol use, and more alcohol-related problems by participants. A larger proportion of social network members reported as light drinkers or abstainers was a significant predictor of more PBS use by participants. Additionally, a larger proportion of high PBS using social network members was a significant predictor of more PBS use and perceived importance of PBS by participants. Closeness (i.e., amount of time spent with the individual social network members) did not moderate any of these associations

description: For the study of citation networks, a challenging problem is modeling the high clustering. Existing studies indicate that the promising way to model the high clustering is a copying strategy, i.e., a paper copies the references of its neighbour as its own references. However, the line of models highly underestimates the number of abundant triangles observed in real citation networks and thus cannot well model the high clustering. In this paper, we point out that the failure of existing models lies in that they do not capture the connecting patterns among existing papers. By leveraging the knowledge indicated by such connecting patterns, we further propose a new model for the high clustering in citation networks. Experiments on two real world citation networks, respectively from a special research area and a multidisciplinary research area, demonstrate that our model can reproduce not only the power-law degree distribution as traditional models but also the number of triangles, the high clustering coefficient and the size distribution of co-citation clusters as observed in these real networks.

description: Abstract: Frailty is a common syndrome in older individuals that is associated with poor cognitive outcome. The underlying brain correlates of frailty are unclear. The aim of this study was to investigate the association between frailty and MRI features of cerebral small vessel disease in a group of non-demented older individuals. We included 170 participants who were classified as frail (n = 30), pre-frail (n = 85) or non-frail (n = 55). The association of frailty and white matter hyperintensity volume and shape features, lacunar infarcts and cerebral perfusion was investigated by regression analyses adjusted for age and sex. Frail and pre-frail participants were older, more often female and showed higher white matter hyperintensity volume (0.69 [95%-CI 0.08 to 1.31], p = 0.03 respectively 0.43 [95%-CI: 0.04 to 0.82], p = 0.03) compared to non-frail participants. Frail participants showed a non-significant trend, and pre-frail participants showed a more complex shape of white matter hyperintensities (concavity index: 0.04 [95%-CI: 0.03 to 0.08], p = 0.03; fractal dimensions: 0.07 [95%-CI: 0.00 to 0.15], p = 0.05) compared to non-frail participants. No between group differences were found in gray matter perfusion or in the presence of lacunar infarcts. In conclusion, increased white matter hyperintensity volume and a more complex white matter hyperintensity shape may be structural brain correlates of the frailty phenotype.

description: vapr is a collection of short stories loosely interconnected via an anthropoid of smoke self-titled the Antimmanuel. vapr is an acronym for VOID & AUGURY & PRESENCE & RESIDUE; there is nothing else, and it is all ephemeral. The Antimmanuel is the guide; it is there with us even when god is not – within capitalism, within religion, within mental health crises, etc. Although very much not a work of Realism, this collection of eight stories grasps for, at the very least, its own author’s understanding of the real – what it feels like to live in middle America in the early 21st century. Ride-share drivers, drone operators, astronauts, sex cults, bimbos, active shooters, drug addicts, moms, dads, and impressionable young men – these are the people of vapr.

title: Harnessing the silver tsunami: An investigation into the benefits and challenges of senior entrepreneurship in Singapore
Creators: name: Chee, Herbert
Publisher: name: Edinburgh Napier University
Year: 2023

description: Singapore is a fast-ageing society and recent Government data indicates that Singapore is facing an impending ‘silver tsunami’. Many researchers have raised the alarm on the problems that such an ageing Singaporean population would bring and how it would negatively affect the economy and society if not well managed. However, this silver tsunami can also be viewed as an opportunity, an impending wave of senior talent that can be harnessed and channelled into increased effective senior entrepreneurship in Singapore. Hence, this thesis seeks to explore an under-researched topic in Asia, namely, what are the benefits of senior entrepreneurship and identify the challenges that potential older entrepreneurs face and highlight potential supporting strategies that can be adopted to alleviate those challenges. The thesis adopts a qualitative interpretivist approach. Data was collected through semi-structured interviews of nine successful senior entrepreneurs who became founders after the age of 50 and also through two focus groups interviews with one group below the age of 50 and the other above age 55. Thematic analysis was used to analyse the collected data. The findings revealed that while business knowledge sharing is one of the benefits that can be leveraged from the senior entrepreneurs, the effective use of technology and positive sales generation were two distinct challenges that senior entrepreneurs often needed additional support with. The recommendations of this research highlight the need for relevant stakeholders to implement further policies and initiatives to assist Singaporean seniors with these potentially problematic areas. One such initiative identified is to create business incubators especially designed for seniors. This research also identified the differing support systems that male and female senior entrepreneurs may require and this is an area that future researchers are encouraged to explore.

description: In the course of the electrification of powertrains, rolling element bearings are increasingly subject to electrical damage. In contrast to mechanically generated pittings, voltage-induced surface damage is a continuous process. Though several approaches for the description of the damage state of a bearing are known, a generally accepted quantification for the bearing damage has not been established yet. This paper investigates surface properties, which can be used as a metric damage scale for the quantification of the electric bearing damage progression. For this purpose, the requirements for suitable surface properties are defined. Afterwards, thrust ball bearings are installed on a test rig, with constantly loaded mechanically and periodically damaged electrically in multiple phases. After each phase, the bearings are disassembled, the bearing surfaces are graded and measured for 45 different standardized surface properties. These properties are evaluated with the defined requirements. For the ones meeting the requirements, critical levels are presented, which allow for a quantified distinction between grey frosting and corrugation surfaces. These values are compared with measurements presented in the literature showing that the identified surface properties are suitable for the quantification of electrical bearing damages.

description: We find two two-qubit states such that any number of copies of one state or the other cannot violate the CHSH Bell inequality. However, their tensor product can produce a CHSH violation of at least 2.023. We also identify a CHSH-local state such that two copies of it are CHSH-violating. The tools employed here can be easily adapted to find instances of non-locality activation in arbitrary Bell scenarios.

Valley Spin Sum Rule for Dirac Fermions: Topological Argument

description: We consider a two-dimensional bipartite lattice system. In such a system, the Bloch band spectrum can have some valley points, around which Dirac fermions appear as the low-energy excitations. Each valley point has a valley spin +1 or -1. In such a system, there are two topological numbers counting vortices and merons in the Brillouin zone, respectively. These numbers are equivalent, and this fact leads to a sum rule which states that the total sum of the valley spins is absent even in a system without time-reversal and parity symmetries. We can see some similarity between the valley spin and chirality in the Nielsen-Ninomiya no-go theorem in odd-spatial dimensions.

description: Die vorgelegte Dissertation untersucht einerseits das Onlinekonsumverhalten von Jugendlichen und jungen Erwachsenen und andererseits die Relevanz der Verbraucher*innenbildung im Rahmen einer Bildung für nachhaltige Entwicklung in Nordrhein-Westfalen. Die Bedeutung des Onlinehandels hat in den letzten Jahren stark zugenommen. Immer häufiger wird der Onlinehandel genutzt, um Produkte und Güter nach Hause liefern zu lassen. Eine Diskussion um unseren Konsum und die Nutzung des Onlinehandels ist unerlässlich für die Sicherung einer nachhaltigen Entwicklung.
 Der Verbraucher*innenbildung kommt hier eine besondere Bedeutung im Rahmen der Förderung einer reflektierten Konsumkompetenz zu. Denn Verbraucher*innenbildung vermittelt Schüler*innen das Wissen und die Kompetenzen, die reflektierte Entscheidungen ermöglichen. Aufgrund des hohen Stellenwertes unter Jugendlichen und jungen Erwachsenen und der zunehmenden Bedeutung des Onlinehandels im Zusammenhang mit einer nachhaltigen Entwicklung ist es sehr wichtig, diese Themen genauer zu untersuchen.

description: Anthology of a Mess is a collection of poems by Yusuf Akman, written at the University of Kentucky. Poems in this thesis deal examine the journey of a poet in three chapters. The first chapter examines myth-making, ekphrasis, and language. While the second one is a genre-defying work in which the modes of mockumentary, lyric essay, and fairy tale co-exist. Last but not least, the final chapter contains autobiographical poems, starting in Turkey and continuing in Kentucky. These poems explore eco-homo eroticism, roadkill, religion, and what it is like to be a queer Turk in Kentucky/the South. Throughout these sections, one can also examine how writing in a second language engenders many possibilities in the English language, how poetry can push the boundaries in terms of genre, and in fact, how it is a constructed term just like everything else.

description: In this work, we calculate the mass spectrum of doubly heavy baryons with the diquark model in terms of the QCD sum rules. The interpolating currents are composed of a heavy diquark field and a light quark field. Contributions of the operators up to dimension six are taken into account in the operator product expansion. Within a reasonable error tolerance, our numerical results are compatible with other theoretical predictions. This indicates that the diquark picture reflects the reality and is applicable to the study of doubly heavy baryons.

See-Saw Masses for Quarks and Leptons in SU(5)

description: We build on a recent paper by Grinstein, Redi and Villadoro, where a see-saw like mechanism for quark masses was derived in the context of spontaneously broken gauged flavour symmetries. The see-saw mechanism is induced by heavy Dirac fermions which are added to the Standard Model spectrum in order to render the flavour symmetries anomaly-free. In this letter we report on the embedding of these fermions into multiplets of an SU(5) grand unified theory and discuss a number of interesting consequences.

The growth of structure in the Szekeres inhomogeneous cosmological models and the matter-dominated era

description: This study belongs to a series devoted to using Szekeres inhomogeneous models to develop a theoretical framework where observations can be investigated with a wider range of possible interpretations. We look here into the growth of large-scale structure in the models. The Szekeres models are exact solutions to Einstein's equations that were originally derived with no symmetries. We use a formulation of the models that is due to Goode and Wainwright, who considered the models as exact perturbations of an FLRW background. Using the Raychaudhuri equation, we write for the two classes of the models, exact growth equations in terms of the under/overdensity and measurable cosmological parameters. The new equations in the overdensity split into two informative parts. The first part, while exact, is identical to the growth equation in the usual linearly perturbed FLRW models, while the second part constitutes exact non-linear perturbations. We integrate numerically the full exact growth rate equations for the flat and curved cases. We find that for the matter-dominated era, the Szekeres growth rate is up to a factor of three to five stronger than the usual linearly perturbed FLRW cases, reflecting the effect of exact Szekeres non-linear perturbations. The growth is also stronger than that of the non-linear spherical collapse model, and the difference between the two increases with time. This highlights the distinction when we use general inhomogeneous models where shear and a tidal gravitational field are present and contribute to the gravitational clustering. Additionally, it is worth observing that the enhancement of the growth found in the Szekeres models during the matter-dominated era could suggest a substitute to the argument that dark matter is needed when using FLRW models to explain the enhanced growth and resulting large-scale structures that we observe today (abridged)
