description: Low-dimensional electronic and glassy phononic transport are two important ingredients of highly-efficient thermoelectric material, from which two branches of the thermoelectric research emerge. One focuses on controlling electronic transport in the low dimension, while the other on multiscale phonon engineering in the bulk. Recent work has benefited much from combining these two approaches, e.g., phonon engineering in low-dimensional materials. Here, we propose to employ the low-dimensional electronic structure in bulk phonon-glass crystal as an alternative way to increase the thermoelectric efficiency. Through first-principles electronic structure calculation and classical molecular dynamics simulation, we show that the $π$-$π$ stacking Bis-Dithienothiophene molecular crystal is a natural candidate for such an approach. This is determined by the nature of its chemical bonding. Without any optimization of the material parameter, we obtain a maximum room-temperature figure of merit, $ZT$, of $1.48$ at optimal doping, thus validating our idea.

Lonergan’s Theory of Historiography and His Metaphysical Presuppositions
Creators: name: Guglielmi, Giuseppe
Publisher: name: Università degli Studi di Cagliari
Year: 2020

description: This article focuses on the importance that Lonergan attributes to historical knowledge (historiography). After having traced the cultural and ecclesial climate that led him to take an interest in the question, this text presents the ambitious project by Lonergan denominated “transcendental method” and of the “functional specializations” in which he articulates this method. Then it analyses the functional specialty “History” and the various related themes: the presuppositions of his theory of historiography, historical objectivity and perspectivism, and the role of values in historical knowledge. In the conclusion, a critical balance is formulated starting from the aspects raised.

description: AIM: The objective of this study is to determine the significant influence of smoking cigarettes on the dental implant survival-failure rate in comparison to the rate in non-smokers.
METHODS: An electronic search was conducted for studies published in English, restricted to the period between 2012 and 2022. Pub-Med and Google Scholar were used to search for articles comparing the success vs. failure rates of dental implants between smokers and non-smokers.
RESULTS: Smokers have a higher failure rate, with the duration and amount of smoking being significant factors compared to non-smokers. Moreover, osseointegration was adversely affected by smoking, and smoking accelerated marginal bone loss. Patients who quit smoking showed the same success rates as non-smokers.
CONCLUSION: Implant insertion is not an absolute contraindication for smokers, but patients should be informed about all risk factors (bone healing issues, osseointegration, and implant failure). They should be aware that consuming cigarettes during the initial healing phase after implant insertion increases the risk of failure. Advising patients to quit smoking is a viable solution that helps accelerate bone healing and increases the rates of osseointegration and implant success.

description: This thesis examines the allegiance of Scottish bishops between 1332, when Edward Balliol invaded Scotland, and 1357, when the Treaty of Berwick established a fragile peace between England and Scotland. This period witnessed the so-called ‘Second War of Scottish Independence’, in which David II fought Balliol and Edward III of England for the Scottish throne. Until now, no study of the ‘Second War’ has examined bishops’ allegiance, nor has any study of the Wars of Independence (1296-1357) supplied a rigorous framework to analyse prelates’ bonds with kings. The thesis addresses this lacuna and seeks to establish a new way of thinking about Scottish allegiance, the hierarchical bond between king and subject. It argues that allegiance was connected but distinct from Scottish regnal identity, by using governmental, ecclesiastical, and chronicle evidence. Chapter one analyses existing scholarship on medieval allegiance and highlights the problematic terminology historians have used to describe allegiance. Chapters two and three establish a new way of approaching allegiance by examining medieval theological and legal conceptions of bishops’ relationships with the king. This is achieved by, first, demonstrating bishops’ power when legitimising royal authority during royal inaugurations and, second, by considering bishops’ legal obligations as subjects and potentates. Chapter four applies these findings to the allegiance of bishops in the conflict between 1332 and 1357. This final chapter demonstrates that bishops’ loyalties were not binary and static but flexible and fluctuating. While some bishops were short-term affiliates of Balliol, many bishops provided continuous support to David throughout the 1330s and 1340s. Therefore, bishops played a crucial role in defending Scotland’s independence. Overall, the thesis demonstrates that allegiance cannot be described merely as a binary between loyalty and disloyalty but must be viewed as a spectrum of behaviour between pro-active service and the fulfilment of legal obligations.

description: AIM: The application of platelet-rich fibrin (PRF) in alveolar ridge preservation (ARP) has been shown to enhance treatment outcomes. The aim of this study is to systematically review the efficacy of PRF in the preservation of alveolar ridge following minimally traumatic tooth extraction.

METHODS: A comprehensive literature search was conducted with the publication date set to the past 10 years. A total of 26 controlled clinical trials met the inclu- sion criteria and were included for review. The outcome parameters analysed included post-operational morbidity, soft tissue healing, changes of alveolar dimension, and bone formation in the socket.

RESULTS: All included studies treated the test sites with PRF, and the control sites were left for spontaneous healing. The tooth extraction procedures were kept min- imally traumatic. A pronounced post-extraction pain reduction effect was reported in the test sites, with corresponding fewer analgesic consumptions. PRF-treated sites demonstrated accelerated soft tissue healing. The applied PRF reduced bone atrophy and led to an appreciable quantity of new bone formation in the socket, thereby sus- taining the bone volume.

CONCLUSION: PRF ameliorates immediate post-operational discomfort, improves soft tissue healing, and enhances bone tissue preservation and regeneration. Clini- cal application of PRF is effective and should be considered as a biomaterial for ARP following dental extractions.

description: The active site of superoxide reductase SOR consists of an Fe2+ center in an unusual [His4 Cys1] square-pyramidal geometry. It specifically reduces superoxide to produce H2O2. Here, we have reacted the SOR from Desulfoarculus baarsii directly with H2O2. We have found that its active site can transiently stabilize an Fe3+-peroxo species that we have spectroscopically characterized by resonance Raman. The mutation of the strictly conserved Glu47 into alanine results in a stabilization of this Fe3+-peroxo species, when compared to the wild-type form. These data support the hypothesis that the reaction of SOR proceeds through such a Fe3+-peroxo intermediate. This also suggests that Glu47 might serve to help H2O2 release during the reaction with superoxide.

description: We calculated the effective vertex of the quark production in the collision of Reggeized quark and Reggeized gluon in the next-to-leading order (NLO). The vertex in question is the missing component of the multi-Regge NLO amplitudes with the quark and gluon exchanges in $t_i$ channels. The calculation allows us to develop the bootstrap approach to the quark Reggeization proof within next-to-leading logarithmic approximation.

The Ethics of Love as Translation of History and Finitude: An Essay from Paul Ricoeur
Creators: name: Guzun, Madalina
Publisher: name: Università degli Studi di Cagliari
Year: 2020

description: Could an ethical reasoning give an answer to the crisis of historicity ? The scope of the present article is to address the question of ethics along with Paul Ricœur, by analyzing the relation between love and justice and by drawing a parallel between this relation and the way in which Jacques Derrida defines translation. Through the Ricœurien description of love as Christian love of enemies and through the description of justice as distributive justice, we show that love corresponds to an anhistorical dimension, which transgresses our facticity, while justice belongs to facticity, finitude and historicity. Their conflict is overcome by Ricœur, who shows that the two are reciprocally dependent. Their relation is nonetheless marked by an asymmetry which does not allows us to consider it as a mere dialectic. Along with Jacques Derrida, we may conceive this relation as a translation and we may thus hermeneutically reconsider the nature of translation itself. This approach sheds a new light both on the Ricœurien relation between love and justice and on the question of historicity.

description: We extend a previous phenomenological analysis of photon lensing in an external gravitational background to the case of a massless neutrino, and propose a method to incorporate radiative effects in the classical lens equations of neutrinos and photons. The study is performed for a Schwarzschild metric, generated by a point-like source, and expanded in the Newtonian potential at first order. We use a semiclassical approach, where the perturbative corrections to neutrino scattering, evaluated at one-loop in the Standard Model, are compared with the Einstein formula for the deflection using an impact parameter formulation. For this purpose, we use the renormalized expression of the graviton/fermion/fermion vertex presented in previous studies. We show the agreement between the classical and the semiclassical formulations, for values of the impact parameter $b_h$ of the neutrinos of the order of $b_h\sim 20$, measured in units of the Schwarzschild radius. The analysis is then extended with the inclusion of the post Newtonian corrections in the external gravity field, showing that this extension finds application in the case of the scattering of a neutrino/photon off a primordial black hole. The energy dependence of the deflection, generated by the quantum corrections, is then combined with the standard formulation of the classical lens equations. We illustrate our approach by detailed numerical studies, using as a reference both the thin lens and the nonlinear Virbhadra-Ellis lens.

description: This paper investigates the utilization of differential thrust to help a commercial aircraft with a damaged vertical stabilizer regain its lateral/directional stability. In the event of an aircraft losing its vertical stabilizer, the consequential loss of the lateral/directional stability and control is likely to cause a fatal crash. In this paper, an aircraft with a completely damaged vertical stabilizer is investigated, and a unique differential thrust based adaptive control approach is proposed to achieve a stable flight envelope. The propulsion dynamics of the aircraft is modeled as a system of differential equations with engine time constant and time delay terms to study the engine response time with respect to a differential thrust input. The proposed differential thrust control module is then presented to map the rudder input to differential thrust input. Model reference adaptive control based on the Lyapunov stability approach is implemented to test the ability of the damaged aircraft to track the model aircraft's (reference) response in an extreme scenario. Investigation results demonstrate successful application of such differential thrust approach to regain lateral/directional stability of a damaged aircraft with no vertical stabilizer. Finally, the conducted robustness and uncertainty analysis results conclude that the stability and performance of the damaged aircraft remain within desirable limits, and demonstrate a safe flight mission through the proposed adaptive control methodology.

description: The purpose of the present study is to investigate the potential economic effects of consolidation of rural administrative districts even though municipal consolidation has been focused on urban areas in Korea. We utilize two methodologies to identify rural districts that can be consolidated. First, we identify rural districts suitable for the consolidation through cluster analyses. Second, we examine the economic effects of the consolidation based on a minimum cost approach. Following the methodologies, we identify four rural regions that are suitable for municipal consolidation. They are Yoenchoen- Dongduchoen, Gosung-Injae, Changnyeong-Uiryeng and Yangsan- Gijang. With respect to per capita expenditure savings projection, Gijang-Yangsan is expected to save the expenditure by 86% through the consolidation and 33% for Gosung-Injae, 23% for Yoenchoen-Dongduchoen and 21% was estimated for Changnyeong-Uiryeng. The results may cast important light on the necessity of consolidation in all four rural regions. While the present study entails limitations in data and empirical applications, it provides a theoretical basis and empirical implications for municipal consolidation in rural regions. The present study concludes with some policy implications and directions for future studies.

description: Some sulfate-reducing and microaerophilic bacteria rely on the enzyme superoxide reductase (SOR) to eliminate the toxic superoxide anion radical (O2*-). SOR catalyses the one-electron reduction of O2*- to hydrogen peroxide at a nonheme ferrous iron center. The structures of Desulfoarculus baarsii SOR (mutant E47A) alone and in complex with ferrocyanide were solved to 1.15 and 1.7 A resolution, respectively. The latter structure, the first ever reported of a complex between ferrocyanide and a protein, reveals that this organo-metallic compound entirely plugs the SOR active site, coordinating the active iron through a bent cyano bridge. The subtle structural differences between the mixed-valence and the fully reduced SOR-ferrocyanide adducts were investigated by taking advantage of the photoelectrons induced by X-rays. The results reveal that photo-reduction from Fe(III) to Fe(II) of the iron center, a very rapid process under a powerful synchrotron beam, induces an expansion of the SOR active site.

description: The ability to generate 3-dimensional models of the developing human kidney via the directed differentiation of pluripotent stem cells-termed kidney organoids-has been hailed as a major advance in experimental nephrology. Although these provide an opportunity to interrogate human development, model-specific kidney diseases facilitate drug screening and even deliver bioengineered tissue; most of these prophetic end points remain to be realized. Indeed, at present we are still finding out what we can learn and what we cannot learn from this approach. In this review, we will summarize the approaches available to generate models of the human kidney from stem cells, the existing successful applications of kidney organoids, their limitations, and remaining challenges.

description: Se la filosofia teoretica non dispone di un insieme definito di metodi e problemi, che cosa la distingue dalle altre discipline filosofiche? Qual è il senso del theorein, se non possiamo più concepire un sapere “primo” puramente contemplativo contrapposto ai saperi “regionali”? È possibile identificare uno stile argomentativo teoretico al di là della divisione tra analitici e continentali? Nato dalla didattica e per la didattica, Dubitare, riflettere, argomentare di Silvana Borutti e Luca Vanzago risponde a queste domande individuando nell'atteggiamento autoriflessivo – inteso come vocazione della filosofia a interrogare i propri presupposti, obiettivi e metodi di ricerca – l'emblema della specificità teoretica. La strategia degli autori è duplice: da una parte, circoscrivere nelle opere dei grandi filosofi il campo semantico «originariamente teoretico» del domandare iniziale (meraviglia, skepsis, dubbio, epochè); dall'altra, impostare ogni capitolo come un esercizio di lettura diretta dei testi, dando risalto alla componente metodologica e argomentativa...

description: The propagation of a probe laser field in a cavity optomechanical system with a Bose-Einstein condensate is studied. The transmission properties of the system are investigated and it is shown that the group velocity of the probe pulse field can be controlled by Rabi frequency of the pump laser field. The effect of the decay rate of the cavity photons on the group velocity is studied and it is demonstrated that for small values of the decay rates, the slope of phase dispersion switches from positive to negative just by changing the Rabi frequency of the pump field. Then, the gain-assisted superluminal light propagation due to the cross-Kerr nonlinearity is established in cavity optomechanical system with a Bose-Einstein condensate. Such behavior can not appear in the pump-probe two-level atomic systems in the normal phase. We also find that the amplification is achieved without inversion in the population of the quantum energy levels.

description: The objective of this study was to examine the transitional experiences of elite female athletic mothers from different sports and how those experiences impacted on their identity. Through the adoption of a phenomenological approach, underpinned by a qualitative research design, in-depth interviews were conducted with five elite female athletes. Two athletes competed in winter sport and the remaining three were distance runners. All participants had become mothers during their elite careers and returned to compete at the same level. Three of the athletes had retired; one retired during the study and one was still competing. In-depth interviews were analysed using thematic analysis allowing key themes to be identified within each athlete’s story. Results revealed six identity-related themes: transitioning to elite sport; being an athlete; organisational stressors; injury; motherhood; retirement. In addition, two other key themes related to management of transition emerged: social support and the nature of the sport. The main conclusions of the study were that winter sports athletes experienced more cultural, organisational and logistical challenges through their career. Furthermore, all five athletes successfully transitioned from athlete to mother athlete but the support received differed between sports. Findings also extended the research related to the way athlete mothers negotiate multiple identities and how they felt combining identities was beneficial to them as athletes at the psychological level. Future research should examine further the differences between different types of winter sport as well as the physical implications during the return to sport phase following childbirth.

Crossover between the two regions is also demonstrated. We verify our theory using both the one-dimensional transverse-field Ising model and the one-dimensional quantum Potts model. Our results confirm that the Schmidt gap can be regarded as a supplement to the local order parameter.

description: We report on the potential of high electron mobility transistors (HEMTs) consisting of high composition AlGaN channel and barrier layers for power switching applications. Detailed 2D simulations show that threshold voltages in excess of 3 V can be achieved through the use of AlGaN channel layers. We also calculate the two-dimensional electron gas (2DEG) mobility in AlGaN channel HEMTs and evaluate their power figures of merit as a function of device operating temperature and Al mole fraction in the channel. Our models show that power switching transistors with AlGaN channels would have comparable on-resistance to GaN-channel based transistors for the same operation voltage. The modeling in this paper shows the potential of high composition AlGaN as a channel material for future high threshold enhancement mode transistors.

description: The self-consistent proton-neutron quasiparticle random phase approximation approach is employed to calculate $β$-decay half-lives of neutron-rich even-even nuclei with $8\leqslant Z \leqslant 30$. A newly proposed nonlinear point-coupling effective interaction PC-PK1 is used in the calculations. It is found that the isoscalar proton-neutron pairing interaction can significantly reduce $β$-decay half-lives. With an isospin-dependent isoscalar proton-neutron pairing strength, our results well reproduce the experimental $β$-decay half-lives, although the pairing strength is not adjusted using the half-lives calculated in this study.

description: Let $K/F$ and $K/L$ be two cyclic Galois field extensions and $D=(K/F,σ,c)$ a cyclic algebra. Given an invertible element $d\in D$, we present three families of unital nonassociative algebras over $L\cap F$ defined on the direct sum of $n$ copies of $D$. Two of these families appear either explicitly or implicitly in the designs of fast-decodable space-time block codes in papers by Srinath, Rajan, Markin, Oggier, and the authors. We present conditions for the algebras to be division and propose a construction for fully diverse fast decodable space-time block codes of rate-$m$ for $nm$ transmit and $m$ receive antennas. We present a DMT-optimal rate-3 code for 6 transmit and 3 receive antennas which is fast-decodable, with ML-decoding complexity at most $\mathcal{O}(M^{15})$.

Fundamental properties of nearby single early B-type stars

description: Fundamental parameters of a sample of 26 apparently slowly-rotating single early B-type stars in the solar neighbourhood are presented and compared to high-precision data from detached eclipsing binaries (DEBs). The data are used to discuss the evolutionary status of the stars in context of the most recent Geneva grid of models. Evolutionary masses plus radii and luminosities are determined to better than typically 5%, 10%, and 20% uncertainty, respectively, facilitating the mass-radius and mass-luminosity relationships to be recovered with a similar precision as derived from DEBs. Good agreement between evolutionary and spectroscopic masses is found. Absolute visual and bolometric magnitudes are derived to typically 0.15-0.20mag uncertainty. Metallicities are constrained to better than 15-20% uncertainty and tight constraints on evolutionary ages of the stars are provided. Signatures of mixing with CN-cycled material are found in 1/3 of the sample stars. Typically, these are consistent with the amount predicted by the new Geneva models with rotation. A few objects are possibly the product of binary evolution. In particular, the unusual characteristics of tau Sco point to a blue straggler nature, due to a binary merger. The accuracy and precision achieved in the determination of fundamental stellar parameters from the quantitative spectroscopy of single early B-type stars comes close (within a factor 2-4) to data derived from DEBs. However, significant systematic differences with data from the astrophysical reference literature are found. Masses are about 10-20% and radii about 25% lower then the recommended values for luminosity class V, resulting in the stars being systematically fainter than assumed usually, by about 0.5mag in absolute visual and bolometric magnitude.

description: Biometric data has been widely adopted across various sectors, including digital identity, artificial intelligence (AI), border control, digital wallets, and national identification systems. While biometric identifiers—such as fingerprints, retina scans, and facial recognition—offer reliable and convenient authentication, they also raise significant concerns regarding privacy and security. This paper examines how biometric data is stored, the vulnerabilities it faces, and the most effective methods for safeguarding it. By highlighting the critical importance of biometric data protection, this study reviews current research on approaches, strategies, and policies that enhance security while preserving the functionality and efficiency of biometric systems.

description: In the framework of relativistic mean field theory, the relativistic neutrino emissivity of the nucleonic and hyperonic direct Urca processes in the degenerate baryon matter of neutron stars are studied. We investigate particularly the influence of the isovector scalar interaction which is considered by exchanging $δ$ meson on the nucleonic and hyperonic direct Urca processes. The results indicate that $δ$ mesons lead to obvious enhancement of the total neutrino emissivity, which must result in more rapid cooling rate of neutron star matter.

description: In this work we present a simple method to reconstruct the complex spectral wavefunction of a biphoton, and hence gain complete information about the spectral and temporal properties of a photon pair. The technique, which relies on quantum interference, is applicable to biphoton states produced with a monochromatic pump when a shift of the pump frequency produces a shift in the relative frequencies contributing to the biphoton. We demonstrate an example of such a situation in type-II parametric down-conversion (SPDC) allowing arbitrary paraxial spatial pump and detection modes. Moreover, our test cases demonstrate the possibility to shape the spectral wavefunction. This is achieved by choosing the spatial mode of the pump and of the detection modes, and takes advantage of spatiotemporal correlations.

description: We propose some multigrid methods for solving the algebraic systems resulting from finite element approximations of space fractional partial differential equations (SFPDEs). It is shown that our multigrid methods are optimal, which means the convergence rates of the methods are independent of the mesh size and mesh level. Moreover, our theoretical analysis and convergence results do not require regularity assumptions of the model problems. Numerical results are given to support our theoretical findings.
