The enigma of plant tubulin detyrosination: lessons from a rice TTL family protein
Creators: name: Zhang, Kunxi
Publisher: name: Karlsruhe
Year: 2020

description: Der Detyrosinierungs- und Retyrosinierungszyklus ist einer der häufigsten posttranslationalen Modifikationsprozesse für α-Tubulin. Die Abspaltung eines konservierten, C-terminalen Tyrosins von α-Tubulin durch eine noch nicht bekannte Tubulin-Tyrosin-Carboxypeptidase (TTC) und die Religation dieses Tyrosins durch eine Tubulin-Tyrosin-Ligase (TTL) ist ein vermutlich gemeinsames Merkmal in allen Eukaryoten. Um diesen Zyklus der De- und Retyrosinierung genauer untersuchen zu können, wurden in unserem Labor transgene Linien erstellt, welche die Tubulin-Tyrosin Kinase aus Reis (nachfolgend als OsTTL bezeichnet) in sowohl Reis, als auch in Tabak BY-2 Zellen mit einem RFP-tag überexprimieren. Überraschenderweise wurde herausgefunden, dass die Überexpression von OsTTL-RFP die relative Verweildauer von detyrosiniertem α-Tubulin in sowohl den Koleoptilen, als auch den Embryonalwurzeln erhöht ist und das dies mit stabileren und weniger transversal orientierten kortikalen Mikrotubuli einhergeht, die das Wachstums der Koleoptile und Seminalwurzeln beeinträchtigen. Pflanzen mit diesem Phänotyp zeigten eine gleichzeitig auftretende Störung in der Organisation der in den Phragmoplasten lokalisierten Mikrotubuli und eine fehlerhafte Orientierung der Zellwände. Folglich verändert die erhöhte Tubulin-Detyrosinierung, welche durch die Überexpression von OsTTL erreicht wurde, die strukturellen und dynamischen Eigenschaften von Mikrotubuli und beeinträchtigt damit die Axialität der Mittellamelle und schließlich das gesamte Pflanzenwachstum. Die Überexpremierung von OsTTL-RFP in einer Mikrotubuli-Marker BY-2-Zelllinie, die NtTUA3-GFP exprimiert, veränderte die Kaltsensorfunktion der kortikalen Mikrotubuli, indem sie die kälteinduzierte Zerlegung der kortikalen Mikrotubuli beschleunigte, begleitet von einem ausgeprägten Kalziumeinstrom, was schließlich zu einer verringerten Kälteakklimatisierung führte. Der Abbau kortikaler Mikrotubuli, die durch die 1%ige n-Butanol induzierte Aktivierung der Phospholipase D (PLD) verursacht wurde, wurde durch eine Überexpression von OsTTL in der Zelllinie NtTAU3 BY-2 gemildert. OsPLDα1, eine Isoform der PLD-Familie aus Reis, die die gemeinsamen Funktionen der PLD vermittelt, wird vorzugsweise mit kortikalen Mikrotubuli, Spindel und Phragmoplastenmikrotubuli lokalisiert. Die Überexpression von OsPLDα1 erhöhte die Häufigkeit von detyrosiniertem α-Tubulin. Diese Ergebnisse deuteten auf eine funktionelle Interaktion zwischen OsPLDα1 und detyrosiniertem α-Tubulin hin. Die Überexpression von OsTTL-RFP erhöhte nicht nur die Menge des α-Tubulin-Proteins, sondern auch die Transkription des α-Tubulin-Gens, sowie die Transkription von OsTTL, was auf eine gegenseitige Regulation der posttranslationalen Modifikation bei der Tubulinsynthese hindeutet.

description: We study twisted Courant sigma models, a class of topological field theories arising from the coupling of 3D 0-/2-form BF theory and Chern-Simons theory and containing a 4-form Wess-Zumino term. They are examples of theories featuring a nonlinearly open gauge algebra, where products of field equations appear in the commutator of gauge transformations, and they are reducible gauge systems. We determine the solution to the master equation using a technique, the BRST power finesse, that combines aspects of the AKSZ construction (which applies to the untwisted model) and the general BV-BRST formalism. This allows for a geometric interpretation of the BV coefficients in the interaction terms of the master action in terms of an induced generalised connection on a 4-form twisted (pre-)Courant algebroid, its Gualtieri torsion and the basic curvature tensor. It also produces a frame independent formulation of the model. We show, moreover, that the gauge fixed action is the sum of the classical one and a BRST commutator, as expected from a Schwarz type topological field theory.

description: Diffusion Models (DMs) have disrupted the image Super-Resolution (SR) field and further closed the gap between image quality and human perceptual preferences. They are easy to train and can produce very high-quality samples that exceed the realism of those produced by previous generative methods. Despite their promising results, they also come with new challenges that need further research: high computational demands, comparability, lack of explainability, color shifts, and more. Unfortunately, entry into this field is overwhelming because of the abundance of publications. To address this, we provide a unified recount of the theoretical foundations underlying DMs applied to image SR and offer a detailed analysis that underscores the unique characteristics and methodologies within this domain, distinct from broader existing reviews in the field. This survey articulates a cohesive understanding of DM principles and explores current research avenues, including alternative input domains, conditioning techniques, guidance mechanisms, corruption spaces, and zero-shot learning approaches. By offering a detailed examination of the evolution and current trends in image SR through the lens of DMs, this survey sheds light on the existing challenges and charts potential future directions, aiming to inspire further innovation in this rapidly advancing area.

description: This paper presents an in-depth examination of the nonlinear deformation induced by dielectric actuation in pre-stressed ideal dielectric elastomers. A nonlinear ordinary differential equation that governs this deformation is formulated based on the hyperelastic model under dielectric stress. By means of numerical integration and neural network approximations, the relationship between voltage and stretch is established. Neural networks are utilized to approximate solutions for voltage-to-stretch and stretch-to-voltage transformations obtained via an explicit Runge-Kutta method. The efficacy of these approximations is illustrated by their use in compensating for nonlinearity through the waveshaping of the input signal. The comparative analysis demonstrates that the approximated solutions are more accurate than baseline methods, resulting in reduced harmonic distortions when dielectric elastomers are used as acoustic actuators. This study highlights the effectiveness of the proposed approach in mitigating nonlinearities and enhancing the performance of dielectric elastomers in acoustic actuation applications.

description: Federated learning (FL) enables collaborative training of a machine learning (ML) model across multiple parties, facilitating the preservation of users' and institutions' privacy by maintaining data stored locally. Instead of centralizing raw data, FL exchanges locally refined model parameters to build a global model incrementally. While FL is more compliant with emerging regulations such as the European General Data Protection Regulation (GDPR), ensuring the right to be forgotten in this context - allowing FL participants to remove their data contributions from the learned model - remains unclear. In addition, it is recognized that malicious clients may inject backdoors into the global model through updates, e.g., to generate mispredictions on specially crafted data examples. Consequently, there is the need for mechanisms that can guarantee individuals the possibility to remove their data and erase malicious contributions even after aggregation, without compromising the already acquired "good" knowledge. This highlights the necessity for novel federated unlearning (FU) algorithms, which can efficiently remove specific clients' contributions without full model retraining. This article provides background concepts, empirical evidence, and practical guidelines to design/implement efficient FU schemes. This study includes a detailed analysis of the metrics for evaluating unlearning in FL and presents an in-depth literature review categorizing state-of-the-art FU contributions under a novel taxonomy. Finally, we outline the most relevant and still open technical challenges, by identifying the most promising research directions in the field.

description: New venture strategy strongly affects its performance and is subject to many changes following the high levels of uncertainty as well as changes in business environment. In some cases incremental changes do not generate anticipated performance, and radical change in strategy occur. These quantum leaps, a phenomenon described in botany as punctuated equilibrium, contradict common incremental Darwinian model of new venture strategy formation. Punctuated Equilibrium was recognized in organizational behavior as well. Yet its mechanisms are still unclear. Inspired by recent explorations in botany, we explore the relationships and mechanisms initiating radical strategic change in high technology new ventures.
title: Convective-scale hybrid data assimilation over the Maritime continent
Creators: name: Lee, Joshua Chun Kwang
Publisher: name: University of Reading
Year: 2024

description: Data assimilation is an important component of numerical weather prediction (NWP);
it is used to estimate realistic initial conditions. In recent years, hybrid data assimilation, which combines the traditional climatological representation of background
error covariances with an ensemble representation, has gained significant traction.
This thesis develops and applies hybrid ensemble-variational data assimilation to a
convective-scale tropical simplified model (ABC-DA) and an NWP system over the
western Maritime Continent (SINGV-DA) to explore its benefits and how it can be
better designed for the tropics.
Firstly, the hybrid ensemble-variational data assimilation approach (hybrid-En3DVar)
was implemented in ABC-DA. Generally, hybrid-En3DVar outperformed the traditional
3DVar data assimilation approaches. The improvements were sensitive to ensemble
size, and were less pronounced when the ensemble was very small. The results also
highlighted how the sub-optimal background error covariance model in 3DVar, which
uses geostrophic balance as a balance constraint, led to erroneous analysis increments
in meridional wind and negatively impacted the forecasts.
Secondly, the hybrid ensemble-variational data assimilation approach was implemented in SINGV-DA. Without proper tuning, the initial hybrid-En3DVar setup
had a relatively neutral impact compared to 3DVar. However, tuning the weightings for hybrid-En3DVar and time-shifting of ensemble perturbations were vital for
improving precipitation forecasts and forecast fits to radiosonde humidity and wind
compared to 3DVar. The results also highlighted how the autocovariance structures
varied between variables, including the presence of robust cross-correlation structures
between the moisture and temperature-related variables in the ensemble-derived background error matrix, which could have physical significance over the Maritime Continent.
Thirdly, the localisation aspect of En3DVar was modified to allow for variable-dependent localisation (prescribing different localisation length-scales for different variables) and selective multivariate localisation (knocking-out by localisation certain multi-variate error covariances) in ABC-DA. This was to address two limitations of traditional
ensemble-variational data assimilation approaches which were pertinent over the tropics. Using selective multivariate localisation was beneficial, particularly when covariances
associated with hydrostatic balance were retained and when zonal wind errors were de-coupled from the mass errors in the cross-covariances. The results also showed that
variable-dependent localisation could be beneficial if the localisation length-scales were
well-tuned for each variable. Both these enhancements within a pure EnVar framework
reduced the forecast root-mean-square errors by about 3-4% for zonal wind and mass
variables. These benefits may also apply to hybrid-En3DVar.

description: The growing prevalence of overweight/obesity in adolescents highlights the significance of studying metabolic syndrome (MetS) in increasingly sedentary adolescents. To date, no study in Sudan has examined the association between MetS and physical activity (PA) among adolescents. This study aimed to assess the association between MetS and its components and PA among Sudanese early adolescents. A cross-sectional assessment was conducted from to 2018 to 2019 on a sample of 921 primary school students from Khartoum State, Republic of Sudan. MetS was defined according to the International Diabetes Federation criteria and a standardized questionnaire was used to assess PA. Metabolic equivalents of task were calculated, and levels of different intensities of PA (tertiles) were identified accordingly. The association between PA and MetS and its components was assessed using a logistic regression model. The participants comprised 388 boys and 533 girls with a mean age of 12.59 ± 1.21 years. The prevalence of MetS was significantly higher in subjects in the 1st PA tertile (least active) than in the 2nd and 3rd (most active) tertiles of PA, and this difference was observed in both boys and girls. After adjusting for other study factors, the odds of MetS among adolescents in the 1st PA tertile were 7 times higher than those in the highest PA tertile (adjusted odds ratio = 7.01, 95% confidence interval: 1.48, 32.99). A physically inactive lifestyle was associated with higher odds of MetS and its components, especially waist circumference and triglyceride levels, in Sudanese early adolescents. This study highlights the importance of promoting PA in this age group.

description: Cornerstones of the Cellular Automaton Interpretation of Quantum Mechanics are its ontological states that evolve by permutations, in this way never creating would-be quantum mechanical superposition states. We review and illustrate this with a classical Ising spin chain. It is shown that it can be related to the Weyl equation in the continuum limit. Yet, the model of discrete spins or bits unavoidably becomes a model of qubits by generating superpositions, if only slightly deformed. We study modifications of its signal velocity which, however, do not relate to mass terms. To incorporate the latter, we consider the Dirac equation in 1+1 dimensions and sketch an underlying discrete deterministic "necklace of necklaces" automaton that qualifies as ontological.

description: In this study, ultrafast optical spectroscopy was employed to elucidate the intricate topological features of EuIn$_2$As$_2$, a promising candidate for a magnetic topological-crystalline axion insulator. Our investigation, focusing on the real-time evolution of topological states, unveiled a narrow surface magnetic gap (2$Δ_0$ $\simeq$ 8.2 meV)) emerging at the antiferromagnetic transition temperature ($T_N$ $\approx$ 16 K). Below $T_N$, two extremely low-energy collective modes, $ω_1$ and $ω_2$, with frequencies of $\sim$9.9 and 21.6 GHz at $T$ = 4 K, respectively, were observed, exhibiting strong temperature dependence. $ω_1$ correlates with an acoustic phonon, while $ω_2$ is associated with a magnon. The results suggest that EuIn$_2$As$_2$ has the potential to manifest a magnetic topological-crystalline axion insulator, presenting a small magnetic energy gap on the (001) surface. The findings further our understanding of the interplay between magnetism and topology in this material, showcasing its potential for applications in quantum information processing and spintronics.

description: Machine-learning methods are gradually being adopted in a wide variety of social, economic, and scientific contexts, yet they are notorious for struggling with exact mathematics. A typical example is computer algebra, which includes tasks like simplifying mathematical terms, calculating formal derivatives, or finding exact solutions of algebraic equations. Traditional software packages for these purposes are commonly based on a huge database of rules for how a specific operation (e.g., differentiation) transforms a certain term (e.g., sine function) into another one (e.g., cosine function). These rules have usually needed to be discovered and subsequently programmed by humans. Efforts to automate this process by machine-learning approaches are faced with challenges like the singular nature of solutions to mathematical problems, when approximations are unacceptable, as well as hallucination effects leading to flawed reasoning. We propose a novel deep-learning interface involving a reinforcement-learning agent that operates a symbolic stack calculator to explore mathematical relations. By construction, this system is capable of exact transformations and immune to hallucination. Using the paradigmatic example of solving linear equations in symbolic form, we demonstrate how our reinforcement-learning agent autonomously discovers elementary transformation rules and step-by-step solutions.

description: Integrating Internet of Things (IoT) technology inside the cold supply chain can enhance transparency, efficiency, and quality, optimizing operating procedures and increasing productivity. The integration of IoT in this complicated setting is hindered by specific barriers that need a thorough examination. Prominent barriers to IoT implementation in the cold supply chain are identified using a two-stage model. After reviewing the available literature on the topic of IoT implementation, a total of 13 barriers were found. The survey data was cross-validated for quality, and Cronbach's alpha test was employed to ensure validity. This research applies the interpretative structural modeling technique in the first phase to identify the main barriers. Among those barriers, "regularity compliance" and "cold chain networks" are key drivers for IoT adoption strategies. MICMAC's driving and dependence power element categorization helps evaluate the barrier interactions. In the second phase of this research, a decision-making trial and evaluation laboratory methodology was employed to identify causal relationships between barriers and evaluate them according to their relative importance. Each cause is a potential drive, and if its efficiency can be enhanced, the system as a whole benefits. The research findings provide industry stakeholders, governments, and organizations with significant drivers of IoT adoption to overcome these barriers and optimize the utilization of IoT technology to improve the effectiveness and reliability of the cold supply chain.

description: We study the Iwasawa theory of $p$-primary Selmer groups of elliptic curves $E$ over a number field $K$. Assume that $E$ has additive reduction at the primes of $K$ above $p$. In this context, we prove that the Iwasawa invariants satisfy an analogue of the Riemann--Hurwitz formula. This generalizes a result of Hachimori and Matsuno. We apply our results to study rank stability questions for elliptic curves in prime cyclic extensions of $\mathbb{Q}$. These extensions are ordered by their absolute discriminant and we prove an asymptotic lower bound for the density of extensions in which the Iwasawa invariants as well as the rank of the elliptic curve is stable.

description: Exciton optomechanics, bridging cavity exciton polaritons and optomechanics, opens new opportunities for the study of light-matter strong interactions and nonlinearities, due to the rich nonlinear couplings among excitons, phonons, and photons. Here, we propose to entangle two exciton modes in an exciton-optomechanics system, which consists of a semiconductor microcavity integrated with two quantum wells. The quantum wells support two exciton modes, which simultaneously couple to an optical cavity mode via a linear dipole interaction and to a mechanical vibration mode via a nonlinear deformation potential interaction. We show that by strongly driving the microcavity with a red-detuned laser field and when the two exciton modes are respectively resonant with the Stokes and anti-Stokes sidebands scattered by the mechanical motion, stationary entanglement between the two exciton modes can be established under realistic parameters. The protocol is within reach of current technology and may become a promising approach for preparing excitonic entanglement.

description: There are two key paradigms for non-equilibrium dynamics: on the one hand, aging towards an equilibrium state that cannot be reached on reasonable timescales; on the other, external driving that can lead to non-equilibrium steady states. We explore how these two mechanisms interact, by studying the behaviour of trap models, which are paradigmatic descriptions of slow glassy dynamics, when driven by trajectory bias towards high or low activity. To diagnose whether the driven systems continue to age, we establish a framework for mapping the biased dynamics to a Markovian time evolution with time-dependent transition rates. We find that the original aging dynamics reacts in two qualitatively distinct ways to the driving: it can be destroyed by driving of any nonzero strength (fragile aging), whereby the dynamics either reaches an active steady state or effectively freezes; or it can persist within a finite range of driving strengths around the undriven case (robust aging). This classification into fragile and robust aging could form the basis for distinguishing different universality classes of aging dynamics.

description: Von den etwa zwei Millionen Tonnen Klärschlamm, die jährlich in Deutschland anfallen, wird aktuell knapp die Hälfte landwirtschaftlich verwertet, während der Rest entweder in Monoverbrennungsanlagen oder in Kohlekraftwerken und Zementfabriken verbrannt wird. Der direkte Einsatz des Klärschlamms in der Landwirtschaft
wird aufgrund der Belastung mit Schwermetallen und insbesondere mit organischen Schadstoffen zunehmend kritisch gesehen, auch von der Politik. So sieht beispielsweise der Koalitionsvertrag zwischen CDU, CSU und SPD für die 18. Legislaturperiode des Deutschen Bundestags den Ausstieg aus der landwirtschaftlichen Klärschlammverwertung vor. Der Anteil der Verbrennung an der Klärschlammentsorgung dürfte deshalb in Zukunft zunehmen. Während bei der Verbrennung zwar die organischen Schadstoffe nahezu vollständig abgebaut werden, gehen die im Schlamm enthaltenen Wertstoffe - insbesondere Phosphor - dem Wirtschaftskreislauf dauerhaft verloren, da die Aschen bisher hauptsächlich deponiert oder zum Bergversatz genutzt werden. Um das Rückgewinnungspotential für Wertstoffe aus Klärschlammaschen bewerten zu können, wurden in einem Vorhaben des Umweltforschungsplans fast sämtliche in Deutschland anfallenden Klärschlammaschen (KSA) aus 24 Monoverbrennungsanlagen über einen Zeitraum von einem Jahr beprobt und grundlegend charakterisiert. Es wurde festgestellt, dass in knapp 300.000 Tonnen Klärschlammasche pro Jahr etwa 19.000 Tonnen Phosphor enthalten, was 13 Prozent der Phosphormenge entspricht, die in Deutschland jährlich für Mineraldünger benötigt wird. Diese Menge könnte schon heute aus Aschen zurückgewonnen werden, die bei der separaten Verbrennung von
Klärschlamm (Monoverbrennung) anfallen. Das Rückgewinnungspotential anderer Rohstoffe wie seltene Erden ist dagegen eher gering.Quelle: Krüger, Oliver; Roskosch, Andrea; Adam, Christian: Monitoring von Klärschlammaschen / Oliver Krüger ; Andrea Roskosch ; Christian Adam. - graph.

description: Many disciplines of science and engineering deal with problems related to compositions, ranging from chemical compositions in materials science to portfolio compositions in economics. They exist in non-Euclidean simplex spaces, causing many standard tools to be incorrect or inefficient, which is significant in combinatorically or structurally challenging spaces exemplified by Compositionally Complex Materials (CCMs) and Functionally Graded Materials (FGMs). Here, we explore them conceptually in terms of problem spaces and quantitatively in terms of computational feasibility.
 This work implements several essential methods specific to the compositional (simplex) spaces through a high-performance open-source library nimplex. Most significantly, we derive and implement an algorithm for constructing a novel n-dimensional simplex graph data structure, which contains all discretized compositions and all possible neighbor-to-neighbor transitions as pointer arrays. Critically, no distance or neighborhood calculations are performed, instead leveraging pure combinatorics and the ordering in procedurally generated simplex grids, keeping the algorithm $\mathcal{O}(N)$, so that graphs with billions of transitions take seconds to construct on a laptop. Furthermore, we demonstrate how such graph representations can be combined to express path-planning problem spaces and to incorporate prior knowledge while keeping the problem space homogeneous. This allows for efficient deployment of existing high-performance gradient descent, graph traversal search, and other path optimization algorithms.

description: As a result of our previous research focussed on benzimidazoles, herein we present design, synthesis, QSAR analysis and biological activity of novel N-substituted benzimidazole derived carboxamides. Carboxamides were designed to study the influence of the number of methoxy groups, the type of the substituent placed at the benzimidazole core on biological activity. Pronounced antioxidative activity displayed unsubstituted 28 (IC50 ≈ 3.78 mM, 538.81 mmolFe2+/mmolC) and dimethoxy substituted derivative 34 (IC50 ≈ 5.68 mM, 618.10 mmolFe2+/mmolC). Trimethoxy substituted 43 and unsubstituted compound 40 with isobutyl side chain at N atom showed strong activity against HCT116 (IC50 ≈ 0.6 µM, both) and H 460 cells (IC50 ≈ 2.5 µM; 0.4 µM), being less cytotoxic towards non-tumour cell. Antioxidative activity in cell generally confirmed relatively modest antioxidant capacity obtained in DPPH/FRAP assays of derivatives 34 and 40. The 3D-QSAR models were generated to explore molecular properties that have the highest influence on antioxidative activity.

Well-posedness for the NLS hierarchy

description: We prove well-posedness for higher-order equations in the so-called NLS hierarchy (also known as part of the AKNS hierarchy) in almost critical Fourier-Lebesgue spaces and in modulation spaces. We show the $j$th equation in the hierarchy is locally well-posed for initial data in $\hat H^s_r(\mathbb{R})$ for $s \ge \frac{j-1}{r'}$ and $1 < r \le 2$ and also in $M^s_{2, p}(\mathbb{R})$ for $s = \frac{j-1}{2}$ and $2 \le p < \infty$. Supplementing our results with corresponding ill-posedness results in Fourier-Lebesgue spaces shows optimality. Using the conserved quantities derived in Koch-Tataru (2018) we argue that the hierarchy equations are globally well-posed for data in $H^s(\mathbb{R})$ for $s \ge \frac{j-1}{2}$.
 Our arguments are based on the Fourier restriction norm method in Bourgain spaces adapted to our data spaces and bi- & trilinear refinements of Strichartz estimates.

Modelling and Classification of Apple Textural Attributes Using Sensory, Instrumental and Compositional Analyses

description: Textural characteristics of fruit are important for their quality, storability, and consumer acceptance. While texture can be evaluated instrumentally or sensorially, instrumental measurements are preferred if they can be reliably related to human perception. The objectives of this research were to validate instrumental measurements with sensory determinations, develop a classification scheme to group apples by their textural characteristics, and create models to predict sensory attributes from instrumental and compositional analyses. The textural characteristics (crispness, hardness, juiciness, and skin toughness) of 12 apple cultivars were evaluated on new and established cultivars. Fruit was also evaluated using five instrumental measurements from TA.XTplus Texture Analyzer, and three compositional determinations. The experiment was repeated for analysis and validation purposes. Principal component (PC) analysis revealed that 95.88% of the variation in the instrumental determinations could be explained by two components (PC 1 and PC 2); which were highly correlated with flesh firmness and skin strength, respectively. Four textural groups of apples were identified, and the accuracy of classification was established at 94.44% by using linear discriminant analysis. The predictive models that were developed between the sensory and instrumental-compositional data explained more than 85% of the variation in the data for hardness and crispness, while models for juiciness and skin toughness were more complex. The work should assist industry personnel to reduce time-consuming and costly sensory testing, yet have an appreciation of the textural traits as perceived by the consumer.

description: We analyze the blackbody radiation problem in the presence of quantum gravity effects encoded in modified dispersion relations. The spectral radiance and the generalized Stefan-Boltzmann law are studied in this context. Furthermore, the regime of low temperatures is also contemplated, where features related to the blackbody thermal laws and the thermodynamic quantities such as energy, pressure, entropy, and specific heat are obtained. Possible implications in compact objects such as neutron stars are also discussed.
