description: Optimal lower bounds for discrepancy in Besov spaces with dominating mixed smoothness are known from the work of Triebel. Hinrichs proved upper bounds in the plane. In this work we systematically analyse the problem, starting with a survey of discrepancy results and the calculation of the best known constant in Roth's Theorem. We give a larger class of point sets satisfying the optimal upper bounds than already known from Hinrichs for the plane and solve the problem in arbitrary dimension for certain parameters considering a celebrated constructions by Chen and Skriganov which are known to achieve optimal $L_2$-norm of the discrepancy function. Since those constructions are $b$-adic, we give $b$-adic characterizations of the spaces. Finally results for Triebel-Lizorkin and Sobolev spaces with dominating mixed smoothness and for the integration error are concluded.
Examining contingencies of the plant community–grazing relationship at multiple scales across North America
Creators: Grenke, Jessica SJ
Publisher: name: University of Alberta Library
Year: 2023

Defoliation is a globally ubiquitous driver of plant community structure and function. However, plant community responses to defoliation remain challenging to predict as they are highly context-dependent. Following defoliation, plant community diversity and production may increase, decrease, or display no change depending on climate, plant neighbors, and the disturbance’s timing, frequency, and location. In this thesis, I disentangle the role of these three core contingencies in mediating the plant community–defoliation relationship across a broad spectrum of scales in time and space. First, I test the assumption that defoliation instigates higher plant production and diversity when applied using high-intensity, short-duration holistic grazing management across the northern great plains. I find holistic grazing management supports fewer vascular plant species at both local and landscape scales despite no difference in plant community composition and variability. However, holistically managed ranches showed markedly higher plant community production than their regionally typical counterparts, with 20% higher aboveground biomass, 26% higher litter mass, and equivalent amounts of surface root biomass. Second, I examined how varying the proportion and patchiness of defoliation disturbances impacted community-wide competition and production using experimental mesocosms. I found that defoliation intensity strongly interacted with the proportion of the plant community disturbed to influence whole-community production and competition. Increased defoliation intensity negatively affected mesocosm production (aboveground, belowground, and total biomass) when all individuals were defoliated but positively affected production where half the mesocosm was defoliated. Finally, I used a meta-analysis of grazing studies across North America to examine how the consequences of grazing exclusion on plant community production and richness vary depending on the weather at the sampling time, climate, year, and study location. Study location and sampling time mediated the effects of grazing exclusion on plant community production and richness. Plant richness, not plant abundance, responded to grazing exclusion differently depending on mean annual precipitation, with less positive effects of exclusion found when precipitation was higher. Data collection within an unusually wet year detected less positive effects of grazing exclusion. Our results demonstrate that climate and weather drive the effects of grazing exclusion on plant communities and that these effects are growing more deleterious toward plant abundance over time. Overall, the results of this thesis promote a new understanding of how grazing management, plant-plant interactions, and study location in time and space modify the plant community–defoliation relationship.

description: Recent observations have led to the establishment of the concordance LCDM model for cosmology. A number of experiments are being planned to shed light on dark energy, dark matter, inflation and gravity, which are the key components of the model. To optimize and compare the reach of these surveys, several figures of merit have been proposed. They are based on either the forecasted precision on the LCDM model and its expansion, or on the expected ability to distinguish two models. We propose here another figure of merit that quantifies the capacity of future surveys to rule out the LCDM model. It is based on a measure of the difference in volume of observable space that the future surveys will constrain with and without imposing the model. This model breaking figure of merit is easy to compute and can lead to different survey optimizations than other metrics. We illustrate its impact using a simple combination of supernovae and BAO mock observations and compare the respective merit of these probes to challenge LCDM. We discuss how this approach would impact the design of future cosmological experiments.

description: We propose a rigorous thermal resonating mean-field theory (Res-MFT). A state is approximated by superposition of multiple MF wavefunctions (WFs) composed of non-orthogonal Hartree-Bogoliubov (HB) WFs. We adopt a Res-HB subspace spanned by Res-HB ground and excited states. A partition function (PF) in a SO(2N) coherent state representation |g> (N:Number of single-particle states) is expressed as Tr(e^{-βH})=2^{N-1} \int dg (β=1/k_BT). Introducing a projection operator P to the Res-HB subspace, the PF in the Res-HB subspace is given as Tr(Pe^{-βH}), which is calculated within the Res-HB subspace by using the Laplace transform of e^{-βH} and the projection method. The variation of the Res-HB free energy is made, which leads to a thermal HB density matrix W_{Res}^{thermal} expressed in terms of a thermal Res-FB operator F_{Res}^{thermal} as W_{Res}^{thermal}={1_{2N}+exp(βF_{Res}^{thermal})}^{-1}. A calculation of the PF by an infinite matrix continued fraction is cumbersome and a procedure of tractable optimization is too complicated. Instead, we seek for another possible and more practical way of computing the PF and the Res-HB free energy within the Res-MFT.

description: Untersucht wird Frauenschmuck aus Niederlegungen der späten Bronzezeit und vorrömischen Eisenzeit in Südskandinavien. In einem interdisziplinären Ansatz werden methodologisch Erkenntnisse der Vergleichenden Religionswissenschaft, insbesondere die Ritualtheorie und das darin inkludierte Opfer, exemplarisch auf das archäologische Material angewendet. Dabei werden religionswissenschaftliche und archäologische Kriterien, die auf eine sakrale Motivation der Niederlegungen schließen lassen, herausgearbeitet. Der sakrale Charakter des bronzenen Frauenschmucks, schwerpunktmäßig des Ringschmuckes, wird dargestellt. Der Ringschmuck eignet sich aufgrund seiner Form, seines Materials und des Prestiges besonders als religiöses Symbol. Methodisch behandelt werden auch die religiöse Symbolik und Merkmale sogenannter „Heiliger Orte“. Die Sakralität „Heiliger Räume“ wird durch ihre Separation von dem alltäglichen Umfeld ausgedrückt. Daher werden hierfür topographisch auffällige Plätze bevorzugt. Abschließend erfolgt eine Deutung der Deponierungen als Opfer innerhalb eines agrarisch geprägten Fruchtbarkeitskults.
description: This study deals with jewelry from metal deposits dated from Late Bronze Age to pre-Roman Iron Age in Southern Scandinavia. In an interdisciplinary framework, methodology from comparative religion, especially ritual theory including offering, is applied on archaeological material. Criteria from comparative religion and archaeology for the sacrality of the hoard finds are developed. The sacral aspects of women jewelry are shown with a special focus on neck rings. Neck rings are particularly suitable as religious symbols because of their form, material and their high prestige. Additionally, religious symbolism and so called “Holy places” are analyzed. The separation from human space underlines their sacral character as “Holy places”. Therefore, topocraphical remarkable places are preferred. Finally, the hoards are interpreted as offerings in an agrarian fertility cult.

description: We discuss, by means of mode-matching analysis for the Dirac equation, how splittings of the Landau-level (LL) degeneracies associated with spin, valley, and layer degrees of freedom affect the ballistic conductance of graphene bilayer. The results show that for wide samples ($W\gg{}L$) the Landauer-Büttiker conductance reaches the maximum $G\simeq{}se^2/(π{h})\times{}W/L$ at the resonance via each LL, with the prefactor varying from $s=8$ if all three degeneracies are preserved, to $s=1$ if all the degeneracies are split. In the absence of bias between the layers, the degeneracies associated with spin and layer degrees of freedom may be split by manipulating the doping and magnetic field; the conductance at the zeroth LL is twice as large, while the conductance at any other LL equals to the corresponding conductance of graphene monolayer. The presence of bias potential allows one also to split the valley degeneracy. Our results show that the charge transfer at each LL has pseudodiffusive character, with the second and third cumulant quantified by ${\cal F}=1/3$ and ${\cal R}=1/15$ (respectively). In case the electrochemical potential is allowed to slowly fluctuate in a finite vicinity of LL, the resulting charge-transfer characteristics are still quantum-limited, with ${\cal F}\simeq{}0.7$ and ${\cal R}\simeq{}0.5$ in the limit of large fluctuations. The above values of ${\cal F}$ and ${\cal R}$ are also predicted to be approached in the limit of high source-drain voltage difference applied. The possible effects of indirect interlayer hopping integrals are also briefly discussed.

Establishing Zebrafish as an Animal Model to Study Drusen
Creators: Humaira, Tasnuva
Publisher: name: University of Alberta Library
Year: 2023

Drusen are extracellular deposits that accumulate in the retina and are a hallmark of age-related macular degeneration (AMD), a leading cause of blindness in the elderly. Sometimes drusen have also been detected in otherwise healthy eyes of younger and elderly patients. Despite their clinical significance, the underlying mechanisms that lead to drusen formation and their impact on retinal function remain poorly understood. Therefore, specific diagnostic tests and treatment are also unavailable.

Animal models can be an essential tool for studying drusen. Zebrafish (Danio rerio), from its first published used in 1981, have emerged as a valuable model organism due to their genetic similarity to humans, ease of genetic manipulation, and fast development. They also share similarity with human eyes and visual system. Rodents are the most common, animal model for vision research. However, they are not well-suited for drusen research because rodents are nocturnal, and their retina is structurally different than the part of human retina where drusen appear. This presents some challenge with using rodents for drusen studies because drusen appears in and degenerates within cone-rich macula of human eye. Zebrafish retina, is cone-rich and more adapted to diurnal light variations, thus overcoming the challenge we face with rodents.

This project determines the earliest age when drusen-like deposits become detectable in rp1l1-/- zebrafish using histological staining techniques. It is the zebrafish line where a mutation has been introduced into the Retinitis pigmentosa 1-like 1 (rp1l1) gene to demonstrate the ocular disease, retinitis pigmentosa. Oil Red O-stained deposits were first detected sporadically in rp1l1-/- fish at 55 days post-fertilization (dpf) and progressed to appear bilaterally in the following months. These progressively increased in size with age, increasing about 3-fold in area in fish up to 1-year post fertilization age. Coincident with the accumulating drusen, the data revealed progressive decreases in the size of the zebrafish Outer Nuclear Layer (ONL).

Unexpectedly, drusen were also detected infrequently in older (1 year old) otherwise normal wildtype zebrafish retinas. This suggests that zebrafish might also be used to model the drusen that appear in healthy human non-AMD retinas, as well as providing the chance to explore structural components of drusen in AMD. Finally, the presence of drusen in 4-year post fertilization WT and rp1l1-/- fish supports the age-related drusen events successfully replicating into zebrafish.

New and advanced animal models are always essential to understand human conditions – both developmental and pathological. Zebrafish is a well-accepted animal model, and this project has laid the groundwork that using the novel rp1l1-/- zebrafish can provide us with the opportunity to understand a complex polygenic condition like drusen and to explore AMD in a comprehensive manner.

Introducing $\RR_0$ the set of non-characteristic points with the Lorentz transform of the space-independent solution as asymptotic profile, we show that $\RR_0$ is open and that the blow-up surface is of class $C^1$ on $\RR_0$. Then, we show the stability of $\RR_0$ with respect to initial data.

Role of Human Fractalkine Receptor Variant in Mouse Brain Development
Creators: Bibi, Sana
Publisher: name: University of Alberta Library
Year: 2023

Multiple sclerosis (MS) is a degenerative disorder of the central nervous system that is triggered in genetically predisposed individuals by environmental insults. In MS, the body’s own immune cells attack and damage myelin and the myelin-producing cells, oligodendrocytes. Genetic factors contribute to both the triggers (susceptibility risk) and drivers (severity risk) of MS. Genetic variants associated with MS severity cluster into the central nervous system development category. However, to date, there are no functional studies on MS severity risk genetic variants in central nervous system development. C-X3-C motif chemokine receptor 1 (CX3CR1), a receptor for chemokine fractalkine (FKN), variants are associated with MS severity. Our lab has shown that FKN-CX3CR1 signaling is important for developmental oligodendrocyte formation. However, whether MS-associated CX3CR1 variants affect brain development and function is unknown.

To address this knowledge gap, I analyze brains from developing and adult mice that express human MS-associated CX3CR1 (I249/M280) variant in place of the mouse CX3CR1. These mice are compared to wild type and CX3CR1 knockout (KO) mice. This study shows that in comparison to WT mice, CX3CR1 (I249/M280) variant brains display i) decreased myelin protein abundance and proportion of oligodendrocytes; ii) altered astrocytes; iii) increased activation of microglia (brain immune cells); and iv) aberrant levels of cytokines. Finally, the CX3CR1 (I249/M280) variant mice exhibit aberrant behaviour in adulthood, such as increased anxiety.

In summary, I show that mice expressing the MS-associated human CX3CR1 variant have delayed myelination and aberrant immune environment during CNS development. These transient developmental defects may lead to aberrant brain function in adulthood. These results suggest that individuals with MS-associated variants may display aberrant brain development, which may contribute to mechanisms of neurodegeneration later in life.

description: The Kondo cloud, represented by the correlations between the magnetic moment and the spin density in the leads of a Kondo setup, is until now eluding its observation. We exploit the unique coupling of spin and direction of motion of the recently discovered helical liquids in a setup with two leads to establish a proportionality between the Kondo cloud and the time resolved current cross correlations. This relation holds around a specific choice of model parameters. Thereby, we provide a new and direct way to detect the Kondo cloud.

Spectra of Discrete Schrödinger Operators with Primitive Invertible Substitution Potentials

subject: FOS: Physical sciences

description: We study the spectral properties of discrete Schrödinger operators with potentials given by primitive invertible substitution sequences (or by Sturmian sequences whose rotation angle has an eventually periodic continued fraction expansion, a strictly larger class than primitive invertible substitution sequences). It is known that operators from this family have spectra which are Cantor sets of zero Lebesgue measure. We show that the Hausdorff dimension of this set tends to $1$ as coupling constant $λ$ tends to $0$. Moreover, we also show that at small coupling constant, all gaps allowed by the gap labeling theorem are open and furthermore open linearly with respect to $λ$. Additionally, we show that, in the small coupling regime, the density of states measure for an operator in this family is exact dimensional. The dimension of the density of states measure is strictly smaller than the Hausdorff dimension of the spectrum and tends to $1$ as $λ$ tends to $0$.
Rational Design and Engineering of Metal-based Nanomaterials for Multifunctional Electrocatalysis
Creators: Li, Hangxuan
Publisher: name: University of Alberta Library
Year: 2023

Multifunctional electrocatalysis plays an important role in renewable energy conversion, supporting a variety of clean energy devices such as fuel cells, electrolyzers, and metal-air batteries. Hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR) are the most significant electrocatalytic reactions that have attracted great research interest. However, several challenges still exist in the design and fabrication of electrocatalysts in terms of cost, performance, and stability.

To address these issues, I attempt to tackle the problems of both cost and electrocatalytic performance, and also fabricate the multifunctional catalysts for different half reactions. Based on the literature review of recent works, I successfully fabricated the transition metal-based nanomaterials supported on the nickel foam and it shows bifunctional electrocatalytic performance for HER and OER.

Chapter 1 is a literature review on novel Pd-based and transition metal-based nanomaterials for multifunctional ORR/OER/HER electrocatalysis in both acidic and alkaline media. The mechanism of electrocatalytic reactions and the challenges of both Pd-based and transition metal-based catalysts are demonstrated. Effective strategies such as alloying design, single-atom catalyst design, interface engineering, and heterojunction construction are summarized.

Chapter 2 clarifies the objectives and experimental design based on the literature review.

Chapter 3 is an experimental section for the design and fabrication of transition metal-based heterogeneous structural Co2P-Ni3S2 hollow nanowires supported on nickel foam (Co2P-Ni3S2/NF). Owing to the multiple active sites provided by transition metal compounds, the large surface area of the unique hollow nanowire morphology, and the synergistic effect of Co2P-Ni3S2 heterostructure interfaces, the as-prepared catalyst exhibits remarkable bifunctional HER/OER performance. It requires ultralow overpotentials of 110, 164 mV for HER and 331.7, 358.3 mV for OER at large current densities of 100, 500 mA cm-2 in alkaline medium, respectively. Impressively, the two-electrode electrolyzer assembled by Co2P-Ni3S2/NF displays a cell voltage of 1.54 V at 10 mA cm-2 and operates stably over 24 h at 100 mA cm-2.

Chapter 4 briefly summarizes recent progress in the literature review and experimental results in the first three chapters, analyzes the existing challenges, and proposes future prospects.

description: Nach der letzten größeren Aufarbeitung frühbronzezeitlicher Bestattungen im südbayerischen Raum Ende der 1970 er Jahre bot sich nach der Entdeckung von fünf neuen Gräberfeldern im Westen des Münchner Stadtgebietes die Möglichkeit einen Kleinraum in dieser Epoche bezüglich ihrer Bestattungen genauer zu beurteilen. Diese Untersuchungen wurden im Rahmen meiner Magisterarbeit an der Ludwigs-Maximilians-Universität München durchgeführt. Da in einer der Nekropolen der Übergang von der frühen zur mittleren Bronzezeit zu fassen war schien es sinnvoll den zeitlichen Rahmen auszudehnen um neue Erkenntnisse über die Belegungsdynamik dieser Bestattungsplätze erlangen zu können. Vor allem die großflächig angelegten Grabungen in Freiham und Maisach-Gernlinden konnten im Gegensatz zu den kleinen Altgrabungen einen ausgedehnten Einblick in die Siedlungslandschaft und der dazugehörigen Bestattungsareale liefern. Da die geringe Anzahl an neuen Gräbern im Arbeitsgebiet keine chronologische Neuordnung der Funde zuließ lag der Fokus der Magisterarbeit auf der Analyse der Bestattungssitten und der damit verbundenen Besonderheiten in der Schotterebene. Durch die anthropologische Analyse eines Großteils des neuen Skelettmaterials konnten einige offene Fragen bezüglich des Bestattungsverhaltens geklärt werden. Neuartige Befundstrukturen, wie z.B. Totenhütten lassen auf weit reichende Kulturkontakte schließen wie auch Altfunde neu bewerten.
description: After the last investigation of Early Bronze Age burials in Southern Bavaria has been made in the late 1970’s five newly discovered cemeteries west of Munich’s township provided an opportunity to examine a small scaled landscape in this certain period regarding the burial customs. These analyses had been undertaken within the scope of my final thesis for M.A. degree at the Ludwigs-Maximilians-University of Munich. Because there was one cemetery in which the transition from Early to Middle Bronze Age could be apprehended it seemed useful to widen the chronological range to gain new knowledge about the dynamic processes within such grave fields. Not like the small scaled old digs the large excavation areas of Freiham and Maisach-Gernlinden opened new insights in the settlement zones and the connected burial places. The amount of graves was too small for making a new chronological order so the focus in this thesis was set upon the analysis of the burial practices and the associated specifics in the gravel plain. Most of the skeletons were examined anthropologically and so some unresolved questions could have been cleared while looking at the burial customs. New types of features, like small buildings erected over graves, give evidence of far-reaching cultural contacts and give us the opportunity to revaluate old findings.

description: We investigate the nature of the insulating phases in a bilayer Hubbard model with intralayer coupling $t$ and interlayer coupling $t_{\perp}$ at large interaction strength $U/t$ and half-filling. We consider a dynamical cluster approximation with a cluster size of $N_c=2\times4$, where short-range spatial fluctuations as well as on-site dynamical fluctuations are emphasized. By varying the band splitting ($t_{\perp}/t$), we find that at $t_{\perp}/t\simeq1.5$ the Mott behavior is rapidly suppressed in the momentum sectors ($π,0$) and ($0,π$). At $t_{\perp}/t\simeq2.5$ Mott features dominate in the momentum sectors ($π,π$) of the bonding band and ($0,0$) of the anti-bonding band and at $t_{\perp}/t\simeq3.0$ a tiny scattering rate is observed in all momentum sectors at the Fermi level, indicating a transition from a Mott to a band insulator. We attribute such a momentum-dependent evolution of the insulating behavior to the competition and cooperation between short-range spatial fluctuations and interlayer coupling $t_{\perp}$ with the help of the Coulomb interaction $U$. Finally, we also discuss the possible appearance of non-Fermi liquid behavior away from half-filling.

The role of obesity and insulin resistance in modulating immune cell function in cancer and liver disease
Creators: Lee, Megan CMH
Publisher: name: University of Alberta Library
Year: 2023

Obesity and associated insulin resistance (IR) represent a significant global health burden, and predispose individuals to develop various diseases, including cancer and liver diseases. Heightened inflammation during obesity can on the one hand exacerbate liver inflammation, while on the other, dampen protective immune responses against tumours. However, the underlying mechanisms remain incompletely understood. My research aims to assess aspects of obesity and alterations in immune function within the context of cancer, focusing on how obesity and IR affects T cell-mediated anti-tumour responses. In addition, my research focuses on the role of Hippo signalling mediators Yes-associated protein (YAP) and Transcriptional co-activator with PDZ-binding motif (TAZ) activity in dendritic cells (DCs) in the development of IR and non-alcoholic fatty liver disease (NAFLD). In response to tension, DCs have enhanced pro-inflammatory function, but also upregulate the expression of TAZ. TAZ is involved in mechanosensing in non-immune cell types and has a homolog known as YAP, suggesting that DC mechanosensing and inflammatory function may involve YAP/TAZ signalling.

Here, I present my findings that diet-induced obesity accelerates tumour growth, which is associated with a decrease in tumour infiltrating lymphocytes. Intratumoural T cells in obese mice also exhibit reduced effector function, but similar levels of exhaustion compared to lean mice. To determine mechanistically how T cell anti-tumour immunity is impaired during obesity, I investigated the role of insulin signalling in T cells, as we found that T cells in obese mice are insulin resistant. To assess the role of insulin signalling in T cell-mediated anti-tumour immunity, I used a mouse model with insulin receptor (INSR)-specific ablation in T cells. Genetic insulin resistance in T cells dampens antigen-specific T cell-mediated immunity, which is associated with decreased production of effector molecules, mirroring the observations in obese mice. Given that obesity imposes a similar phenotype, this supports the notion that obesity impairs T cell-mediated anti-tumour responses through inducing IR. This offers new insight into how obesity impairs immune responses in cancer, and provides implications for the potential of immunotherapies targeting immune cell metabolism against cancer.

I also report that YAP/TAZ in DCs, which we previously observed to be important for DCs’ proinflammatory function, does not play a significant role in the pathogenesis of IR, NAFLD, and liver fibrosis in a high fat high sucrose model.

My findings highlight the complex signals that modulate immunity during obesity, which awaits further investigation for better understanding to ultimately develop therapeutics to improve health and blunt disease.

Simulation-based Sensor Configuration Optimization to Detect Human Activities in Smart Indoor Spaces
Creators: Golestan-Irani, Shadan
Publisher: name: University of Alberta Library
Year: 2023

Smart indoor spaces include a network of interconnected sensors, predictive models, and actuators to sense occupants’ activities and act to improve living. These ubiquitous systems are increasingly popular due to their potential to improve energy efficiency, comfort, and safety in buildings. Typically, the sensors collect data on the environment, while the predictive models use this data to predict the environment's activities and state. The actuators then act on the environment to change the environment's state to a desired one.

The design of smart indoor spaces is a challenging task that requires a lot of effort and time. One critical aspect of the design process is finding a suitable sensor configuration, as different applications require different sensor configuration deployments. The quality of the sensor configuration is critical for the system's overall effectiveness, as inaccurate or incomplete sensor data can lead to poor performance.

To address these challenges, designers of such systems iteratively deploy and modify different sensor configurations to find the one that meets their needs. This process is complex and time-consuming. Alternatively, simulation methodologies have been proposed to facilitate the design process because they offer fast, reproducible, and easy prototyping. Simulation allows designers to test and evaluate different sensor configurations in a virtual environment, reducing the need for expensive and time-consuming physical deployments. However, current simulation approaches still require significant effort and expertise to optimize the sensor configuration accurately.

This thesis proposes a simulation-driven sensor configuration evaluation framework that can optimize the sensor configuration effectively for various applications. Such a framework evaluates and optimizes different sensor configurations efficiently, leading to the development of more effective smart indoor spaces. The framework is evaluated in terms of 1) the fidelity of its simulation methodologies, 2) the quality of the sensor configurations it proposes, and 3) the framework’s scalability considering the sensor numbers and types.
Bag vs. NJL models for color-flavor-locked strange quark matter

description: We compare the mass-radius relationship of strange stars obtained in two theoretical frameworks describing the color-flavor-locking state of dense quark matter: The semi-empirical MIT model and a self-consistent approach using the Nambu-Jona-Lasinio (NJL) model. In the simplest MIT model extended to include pairing, one can make the equation of state stiffer by increasing the gap parameter so that larger maximum masses for these objects can be reached. In the NJL model, however, such an effect is not possible. To increase the gap parameter within the NJL model to values comparable to those considered in the MIT case, a noticeably increase of the diquark-coupling-constant strength is needed, but this in turn softens the equation of state producing a lower maximum star mass. This behaviour is interpreted as signalling the system crossover at high diquark coupling from a BCS regime to a BEC one, a process that cannot be reproduced within the simple MIT prescription.

description: Two-dimensional (2D) atomic crystals, such as graphene and atomically thin transition metal dichalcogenides (TMDCs), are currently receiving a lot of attention. They are crystalline, and thus of high material quality, even so, they can be produced in large areas and are bendable, thus providing opportunities for novel applications. Here, we report a truly 2D p-n junction diode, based on an electrostatically doped tungsten diselenide (WSe2) monolayer. As p-n diodes are the basic building block in a wide variety of optoelectronic devices, our demonstration constitutes an important advance towards 2D optoelectronics. We present applications as (i) photovoltaic solar cell, (ii) photodiode, and (iii) light emitting diode. Light power conversion and electroluminescence efficiencies are ca. 0.5 % and 0.1 %, respectively. Given the recent advances in large-scale production of 2D crystals, we expect them to profoundly impact future developments in solar, lighting, and display technologies.

description: An integer additive set-indexer is defined as an injective function $f:V(G)\rightarrow 2^{\mathbb{N}_0}$ such that the induced function $g_f:E(G) \rightarrow 2^{\mathbb{N}_0}$ defined by $g_f (uv) = f(u)+ f(v)$ is also injective, where $f(u)+f(v)$ is the sumset of $f(u)$ and $f(v)$. If $g_f(uv)=k \forall uv\in E(G)$, then $f$ is said to be a $k$-uniform integer additive set-indexers. An integer additive set-indexer $f$ is said to be a weak integer additive set-indexer if $|g_f(uv)|=max(|f(u)|,|f(v)|) \forall uv\in E(G)$. We have some characteristics of the graphs which admit weak integer additive set-indexers. We already have some results on the admissibility of weak integer additive set-indexer by certain graphs and finite graph operations. In this paper, we study further characteristics of certain graph products like cartesian product and corona of two weak IASI graphs and their admissibility of weak integer additive set-indexers and provide some useful results on these types of set-indexers.

description: AIM: To evaluate the clinical and radiographic outcomes of various augmentation materials and surgical techniques in alveolar ridge preservation procedures compared to natural post-extraction socket healing.

METHODS: A literature search was conducted using the PubMed/MEDLINE database, focusing on the efficacy of different augmentation materials. The initial search yielded 291 studies, which were screened to exclude duplicates and irrelevant entries. Full texts of potentially relevant articles were assessed based on predefined inclusion criteria: studies had to be randomized controlled trials or clinical studies with a minimum follow-up of two months.

RESULTS: In total, 19 studies were ultimately included into the analysis. Alveolar ridge preservation (ARP) procedures are more effective than natural healing in minimizing post-extraction bone resorption, preserving both horizontal and vertical bone dimensions. Cortico-cancellous porcine bone particles and alloplastic materials yield superior results in maintaining alveolar ridge dimensions compared to control groups. Platelet-rich fibrin also reduces bone resorption and enhances preservation. Barrier membranes in ARP procedures further improve outcomes.

CONCLUSION: Future research should refine ARP techniques and materials, focusing on long-term effectiveness and practicality. Investigations into cost-effectiveness and ease of application will promote broader adoption. By implementing tailored ARP strategies, dental professionals can enhance the long-term success of restorations, sustaining patients' health, function, and aesthetics.

Fermi surface renormalization and quantum confinement in the two-coupled chains model

description: We address the problem of the Fermi surface renormalization and the quantum confinement regime (QCR) in the two coupled chains model(TCCM) of spinless fermions. We perform a self-consistent calculation of the renormalization group(RG) flows of the renormalized TCCM couplings and quasiparticle weight. On top of that we take explicitly into account the renormalization of the Fermi surface. The flow of the difference of the renormalized Fermi wave vectors associated with the bonding and antibonding bands has a dramatic effect on the single particle spectrum. Although the quasiparticle amplitude is nullified already at intermediate coupling the QCR is only observed at strong coupling. The state associated with this regime has a charge gap and it is not a Luttinger liquid. In contrast, the Fermi liquid regime is stabilized by the umklapp "$g_2$--like" interactions at very weak coupling regime.
