description: The physiologist Zwaardemaker (1857-1930) conducted extensive research into the relationship between radioactivity and the functioning of the heart, later in a broader sense also called bioradioactivity. For 15 years, from 1915 until his death in 1930, Zwaardemaker worked on this project and about 25 dissertations were devoted to it. The very extensive research project ended abruptly at his death. What exactly did the investigation entail and why was it not continued?

Angles in the SI: treating the radian as an independent, unhidden unit does not require the redefinition of the term frequency or the unit hertz
Creators: name: Quincey, Paul
Publisher: name: arXiv
Year: 2021
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: Some recent papers have argued that frequency should have the dimensions of angle/time, with the consequences that 1 Hz = $2π$ rad/s instead of 1 s$^{-1}$, and also that $ν= ω$ and $h = \hbar$. This letter puts the case that this argument redefines the quantity frequency and then draws conclusions from equations that rely on the standard definition being used. The problems that this redefinition is designed to address arise from the widespread unstated adoption of the Radian Convention, which treats the radian as a dimensionless quantity equal to the number 1, in effect making the radian a hidden unit. This convention is currently built-in to the SI, when it should be separable from it. The unhelpful status of angles in the SI can be remedied with minimal disruption by (1) changing the definition of the radian from a radian equals 1 m/m to e.g. a right angle equals $π/2$ radians, and (2) acknowledging that the adoption of the Radian Convention is acceptable, when made explicit. The standard definitions of frequency and the hertz should remain unchanged.

description: In a previous work (Hernández-Bernal et al. 2021) we performed an observational analysis of the Arsia Mons Elongated Cloud (AMEC), which stands out due to its impressive size and shape, quick dynamics, and the fact that it happens during the martian dusty season. Observations show that its morphology can be split in a head, on the western slope of the volcano of around 120 km in diameter; and a tail, that expands to the west reaching more than 1000 km in length, making the AMEC the longest orographic cloud observed so far in the solar system. In this work we run the LMD (Laboratoire de Météorologie Dynamique) Mesoscale Model to gain insight into the physics of the AMEC. We note that it is coincident in terms of local time and seasonality with the fastest winds on the summit of Arsia Mons. A downslope windstorm on the western slope is followed by a hydraulic-like jump triggering a strong vertical updraft that propagates upwards in the atmosphere, causing a drop in temperatures of down to 30K at 40-50 km in altitude, spatially and temporarily coincident with the observed head of the AMEC. However the model does not reproduce the microphysics of this cloud: the optical depth is too low and the expansion of the tail does not happen in the model. The observed diurnal cycle is correctly captured by the model for the head of the cloud. This work raises new questions that will guide future observations of the AMEC.
Ground-state properties of the attractive one-dimensional Bose-Hubbard model

description: We study the ground state of the attractive one-dimensional Bose-Hubbard model, and in particular the nature of the crossover between the weak interaction and strong interaction regimes for finite system sizes. Indicator properties like the gap between the ground and first excited energy levels, and the incremental ground-state wavefunction overlaps are used to locate different regimes. Using mean-field theory we predict that there are two distinct crossovers connected to spontaneous symmetry breaking of the ground state. The first crossover arises in an analysis valid for large L with finite N, where L is the number of lattice sites and N is the total particle number. An alternative approach valid for large N with finite L yields a second crossover. For small system sizes we numerically investigate the model and observe that there are signatures of both crossovers. We compare with exact results from Bethe ansatz methods in several limiting cases to explore the validity for these numerical and mean-field schemes. The results indicate that for finite attractive systems there are generically three ground-state phases of the model.

description: We demonstrate control of the electron number down to the last electron in tunable few-electron quantum dots defined in catalytically grown InAs nanowires. Using low temperature transport spectroscopy in the Coulomb blockade regime we propose a simple method to directly determine the magnitude of the spin-orbit interaction in a two-electron artificial atom with strong spin-orbit coupling. Due to a large effective g-factor |g*|=8+/-1 the transition from singlet S to triplet T+ groundstate with increasing magnetic field is dominated by the Zeeman energy rather than by orbital effects. We find that the spin-orbit coupling mixes the T+ and S states and thus induces an avoided crossing with magnitude $Δ_{SO}$=0.25+/-0.05 meV. This allows us to calculate the spin-orbit length $λ_{SO}\approx$127 nm in such systems using a simple model.

description: We study the thermodynamics of small black holes in compactified spacetimes of the form R^(d-1)x S^1. This system is analyzed with the aid of an effective field theory (EFT) formalism in which the structure of the black hole is encoded in the coefficients of operators in an effective worldline Lagrangian. In this effective theory, there is a small parameter $λ$ that characterizes the corrections to the thermodynamics due to both the non-linear nature of the gravitational action as well as effects arising from the finite size of the black hole. Using the power counting of the EFT we show that the series expansion for the thermodynamic variables contains terms that are analytic in $λ$, as well as certain fractional powers that can be attributed to finite size operators. In particular our operator analysis shows that existing analytical results do not probe effects coming from horizon deformation. As an example, we work out the order $λ^2$ corrections to the thermodynamics of small black holes for arbitrary d, generalizing the results in the literature.

description: It is known that some of the deeply-virtual-Compton-scattering observables, for instance, the beam-charge asymmetry in the hard electroproduction of real photons on the nucleon, are extremely sensitive to the magnitude of D-term appearing in the parameterization of the generalized parton distributions. We report a theoretical analysis of both the isoscalar and isovector parts of the nucleon D-term within the framework of the chiral quark soliton model, without recourse to the derivative expansion type approximation used in previous works.

description: The wolf motif, one of the most important motifs of Turkic mythology, based on afundamental cult, the cult of the wolf. This animal, which called "wolf" in Oghuz language, called“böri” in Common Turkish. Since it thought that the historical development of language alsorepresents cultural development, an examination of the etymology of the word “böri” may revealsome philological and mythological results. When the etymological origin of the word is analysed,it will be seen that it can be traced back to the Proto-Altaic Language Period, one of the oldestknown words of Turkic has been uncovered, and when compared with the languages within theframework of the Altaic language family hypothesis, it will be seen that evidence of Altaic languageunity has been revealed. On the other hand, important mythological details about the cult of thewolf revealed and clues to the earliest times in the history of Turkic thought obtained. In the Han-shu, a Chinese history written in 111 AD, the word " 拊離 (fǔ-lí)" appears in the title of the Wu-sunruler who was killed in 30 BC as a result of a throne dispute. However, it was determined that theWu-sun ruler received this title from the Xiong-nu (Asian Huns) and the first known linguistic linkbetween Turks and Xiong-nu was established. In addition, the word "böri" has found to be commonin Xiong-nu language, Common Turkish, Mongolian, Korean, Japanese, Manchu-Tungus, otherlanguages thought to be in the Altaic language family, and a word from the Proto-Altaic LanguagePeriod has reconstructed for the first time. Also based on the word "böri", it concluded that Xiong-nu language is closer to Turkish than other Altaic languages.

Ειδότερα μελετήθηκε η εγκεφαλική ενεργοποίηση 6 ατόμων σε 2 διαφορετικές δραστηριότητες. Αναλυτικότερα, το κάθε άτομο συμμετείχε σε τέσσερις συνεδρίες καθεμία από τις οποίες περιείχε μία περίοδο ηρεμίας, πέντε προβλήματα κατανόησης κώδικα και πέντε αναγνώρισης των συντακτικών λαθών του κώδικα. Ακόμη, οι δραστηριότητες που περιελάμβαναν την κατανόηση κώδικα διαχωρίστηκαν σε δύο επιμέρους υποκατηγορίες, τις δύσκολες και εύκολες δραστηριότητες κατανόησης κώδικα, έχοντας ως βάση την κλίμακα βαθμολόγησης την οποία έδωσε το κάθε άτομο. Η καταγραφή του σήματος κατά τη διάρκεια του πειράματος έγινε με τη χρήση 14 ηλεκτροδίων.Μελετήσαμε τις ενέργειες των σημάτων και χρησιμοποιήσαμε τη μέθοδο Rankfeatures για την ταξινόμηση και επιλογή χαρακτηριστικών.Ακόμη για την ταξινόμηση των δεδομένων χρησιμοποιήθηκε Support Vector Machine (SVM) προκειμένου βρούμε διαφορές στην εγκεφαλική δραστηριότητα τόσο σε επίπεδο ατόμου όσο και συνόλου. Για την επιβεβαίωση των αποτελεσμάτων χρησιμοποιήθηκαν μέθοδοι Cross Validation, όπως οι Leave One Out Cross Validation και η k-fold Cross Validation. Ακόμη χρησιμοποίηθηκε η μέθοδος Phase Locking Value (PLV), για τη μελέτη του συγχρονισμού των νευρώνων. Τα ευρήματά μας δείχνουν την εργοποίηση της θ και β μπάντας κατά τη διάρκεια εκτέλεσης πιο απαιτητικών δραστηριοτήτων.
description: In this particular research, we are interested in finding patterns that can be spotted during program comprehension. More specifically, the brain activation of 6 subjects was examined while two different programming tasks were taking place. Furthermore, each subject participated in four sessions each of which included a Resting State period, 5 Comprehension Tasks and 5 Syntax Tasks. In addition, Comprehension Tasks were separated in Difficult and Easy tasks using the grades provided by the subjects. During the experiment the brain signals were recorded using a 14 electrode EEG Headset. We examined the signals in matters of energy and used Rankefeatures for feature ordering and selection. Furthermore, classification was performed using Support Vector Machine learning methods in order to find the differences between the tasks both in single subject analysis and considering the recorded data of all subjects as a whole. The classifier was tested upon its performance using Cross Validation methods, such as Leave One Out Cross Validation and k-fold Cross Validation. Neural synchrony was also part of this research, while using Phase Locking Value (PLV) for the estimation. Our findings indicate that theta band is more activated during more challenging tasks. Furthermore, there are indications that beta band is also activated in some cases.

description: In this paper, we study the domain wall motion induced by vertical current flow in asymmetric magnetic tunnel junctions. The domain wall motion in the free layer is mainly dictated by the current-induced field-like torque acting on it. We show that as we increase the MTJ asymmetry, by considering dissimilar ferromagnetic contacts, a linear-in-voltage field-like torque behavior is accompanied by an enhancement in the domain wall displacement efficiency and a higher degree of bidirectional propagation. Our analysis is based on a combination of a quantum transport model and magnetization dynamics as described by the Landau-Lifshitz-Gilbert equation, along with comparison to the intrinsic characteristics of a benchmark in-plane current injection domain wall device.

description: We report $^{12}$CO($J=$3--2) observations of 15 nearby elliptical galaxies carried out with the ASTE telescope. Thirteen were selected without regard to the presence of other tracers of cold interstellar matter. CO emission was detected from three of the galaxies, two of which are undetected by IRAS at 100 microns, suggesting that cold ISM may be present in more ellipticals than previously thought. The molecular gas masses range from $2.2 \times 10^6$ to $4.3 \times 10^8$ $M_\odot$. The ratio of the CO(3--2) and (1--0) lines, $R_{31}$, has a lower value for elliptical galaxies than for spiral galaxies except for NGC 855, for which the value is close to the mean for spirals. The molecular gas in NGC 855 has a mean density in the range 300 -- 1000 cm$^{-3}$ adopting a temperature range of 15 -- 100 K.

description: We analyze the prospects of observing lepton flavour violation in future e-e- and e+e- linear colliders in scenarios where the gravitino is the lightest supersymmetric particle, and the stau is the next-to-lightest supersymmetric particle. The signals consist of multilepton final states with two heavily ionizing charged tracks produced by the long-lived staus. The Standard Model backgrounds are very small and the supersymmetric backgrounds can be kept well under control by the use of suitable kinematical cuts. We discuss in particular the potential of the projected International Linear Collider to discover lepton flavour violation in this class of scenarios, and we compare the estimated sensitivity with the constraints stemming from the non-observation of rare decays.

We find that spontaneous emission rates are strongly influenced by far off-resonant modes of the cavity and can be understood within a semiclassical circuit model. A careful analysis of the spontaneous qubit decay into a microwave transmission-line cavity can accurately predict the qubit lifetimes over two orders of magnitude in time and more than an octave in frequency. Coherence times $T_1$ and $T_2^*$ of more than a microsecond are reproducibly demonstrated.

description: The equilibration of sinusoidally modulated distribution of the kinetic temperature is analyzed in the $β$-Fermi-Pasta-Ulam-Tsingou chain with different degrees of nonlinearity and for different wavelengths of temperature modulation. Two different types of initial conditions are used to show that either one gives the same result as the number of realizations increases and that the initial conditions that are closer to the state of thermal equilibrium give faster convergence. The kinetics of temperature equilibration is monitored and compared to the analytical solution available for the linear chain in the continuum limit. The transition from ballistic to diffusive thermal conductivity with an increase in the degree of anharmonicity is shown. In the ballistic case, the energy equilibration has an oscillatory character with an amplitude decreasing in time, and in the diffusive case, it is monotonous in time. For smaller wavelength of temperature modulation, the oscillatory character of temperature equilibration remains for a larger degree of anharmonicity. For a given wavelength of temperature modulation, there is such a value of the anharmonicity parameter at which the temperature equilibration occurs most rapidly.

Trompeter et al., Phys. Rev. Lett. \textbf{96}, 053903 (2006)]. We identify the Zener tunneling regime at the crossing of two Bloch bands, which occurs in a generic case of the Bragg reflection when the Bloch index crosses the edge of the irreducible Brillouin zone. Similarly, the higher-order Zener tunneling involves four Bloch bands when the Bloch index passes through a high-symmetry point on the edge of the Brillouin zone. We derive simple analytical models that describe the tunneling effect, and calculate the corresponding tunneling probabilities.

description: The EU has been on track toward growing disunity along geographical and political lines, expressed in growing anti-EU sentiments and the rise of Euroskeptic forces. However, Russia’s invasion of Ukraine seems to have functioned as a source of unity – revitalizing the European project by creating alliances in response to an external threat. However, as the war drags on, it begs the question of how brittle its new-found unity may be. This study thus seeks to examine the extent to which the war has mended the geographical and political divisions in the EU. Focusing on elite cohesion, we analyse social media interaction to provide a relational view of the alliances of the members of the European Parliament. We find that parliamentarians did not become more cohesive: East-Western division remains pronounced, and Euroskeptic political groups became further isolated. These findings imply that Euroskeptic groups will likely continue to be a source of contestation inside of the European Union.

description: Sociocultural norms serve as guiding principles for personal conduct in social interactions, emphasizing respect, cooperation, and appropriate behavior, which is able to benefit tasks including conversational information retrieval, contextual information retrieval and retrieval-enhanced machine learning. We propose a scalable approach for constructing a Sociocultural Norm (SCN) Base using Large Language Models (LLMs) for socially aware dialogues. We construct a comprehensive and publicly accessible Chinese Sociocultural NormBase. Our approach utilizes socially aware dialogues, enriched with contextual frames, as the primary data source to constrain the generating process and reduce the hallucinations. This enables extracting of high-quality and nuanced natural-language norm statements, leveraging the pragmatic implications of utterances with respect to the situation. As real dialogue annotated with gold frames are not readily available, we propose using synthetic data. Our empirical results show: (i) the quality of the SCNs derived from synthetic data is comparable to that from real dialogues annotated with gold frames, and (ii) the quality of the SCNs extracted from real data, annotated with either silver (predicted) or gold frames, surpasses that without the frame annotations. We further show the effectiveness of the extracted SCNs in a RAG-based (Retrieval-Augmented Generation) model to reason about multiple downstream dialogue tasks.

description: The magnetic polarizability of the neutral pion has been calculated in the background magnetic-field formalism of Lattice QCD. In this investigation, the chiral extrapolation of these lattice results is considered in a formalism preserving the exact leading nonanalytic terms of chiral perturbation theory. The $n_f = 2 + 1$ numerical simulations are electro-quenched, such that the virtual sea-quarks of the QCD vacuum do not interact with the background field. To understand the impact of this, we draw on partially quenched chiral perturbation theory and identify the leading contributions of quark-flow connected and disconnected diagrams. While electro-quenching does not impact the leading-loop contribution to the magnetic polarizability, the loops which generate the leading term have yet to be considered in lattice QCD simulations. Lattice QCD results are used to constrain the analytic terms in the chiral expansion and supplementing those with the two-loop result from chiral perturbation theory enables an evaluation of the polarizability at the physical quark mass. The resulting magnetic polarizability of the neutral pion is $β_{π^0}=3.44(19)^{\rm stat}(37)^{\rm syst}\times 10^{-4}$ fm$^3$, which lies just above the $1 σ$ error bound of the experimental measurement.

description: This letter proposes a method of global localization on a map with semantic object landmarks. One of the most promising approaches for localization on object maps is to use semantic graph matching using landmark descriptors calculated from the distribution of surrounding objects. These descriptors are vulnerable to misclassification and partial observations. Moreover, many existing methods rely on inlier extraction using RANSAC, which is stochastic and sensitive to a high outlier rate. To address the former issue, we augment the correspondence matching using Vision Language Models (VLMs). Landmark discriminability is improved by VLM embeddings, which are independent of surrounding objects. In addition, inliers are estimated deterministically using a graph-theoretic approach. We also incorporate pose calculation using the weighted least squares considering correspondence similarity and observation completeness to improve the robustness. We confirmed improvements in matching and pose estimation accuracy through experiments on ScanNet and TUM datasets.

description: Due to the weak current non-conservation the diffractive excitation of charm and strangeness dominates the longitudinal structure function $F_L(x,Q^2)$ of neutrino DIS at small Bjorken $x$. Based on the color dipole BFKL approach we report quantitative predictions for this effect in the kinematical range of the CCFR/NuTeV experiment. We comment on the relevance of our findings to experimental tests of PCAC.

description: We examine cosmological constraints from high precision weak lensing surveys including super-sample covariance (SSC) due to the finite survey volume. Specifically, we focus on the contribution of {\it beat coupling} in the intrinsic alignments as a part of full cosmic shear signal under flat sky approximation. The SSC-effect grows by going to lower redshift bin and indicates considerable footprint on the intermediate and high multipoles for cumulative signal to noise ratio (SNR). The SNR is reduced by $\approx 10\%$ as a consequence of including the intrinsic alignments super-sample covariance, for the full cosmic shear signal, depending on the amplitude of intrinsic alignments, the ellipticity dispersion and the survey redshift ranges, while the contribution of photometric redshift error can be ignored in the cumulative signal to noise ratio. Using the Fisher-matrix formalism, we find that the impact of large modes beyond the volume of the surveys on the small modes alters the intrinsic alignments. However, corresponding impact on the cosmological parameters estimation is marginal compared to that of for gravitational weak lensing, particularly, when all available redshift bins are considered. Our results also demonstrate that, including SSC-effect on the intrinsic alignments in the analytical covariance matrix of full cosmic shear leads to increase marginally the confidence interval for $σ_8$ by $\approx 10\%$ for a sample with almost high intrinsic alignments amplitude.

description: In this article, the free field theory limit of operators dual to giant gravitons with open strings attached are studied. We introduce a graphical notation, which employs Young diagrams, for these operators. The computation of two point correlation functions is reduced to the application of three simple rules, written as graphical operations performed on the Young diagram labels of the operators. Using this technology, we have studied gravitational radiation by giant gravitons and bound states of giant gravitons, transitions between excited giant graviton states and joining of open strings attached to the giant.

description: We study a question of density of Lipschitz mappings in the Sobolev class of mappings from a closed manifold into a singular space. The main result of the paper shows that if we change the metric in the target space to a bi-Lipschitz equivalent one, than the property of the density of Lipschitz mappings may be lost.

description: We conduct experiments with force-free magnetically-driven rigid helical swimmers in Newtonian and viscoelastic (Boger) fluids. By varying the sizes of the swimmer body and its helical tail, we show that the impact of viscoelasticity strongly depends on the swimmer geometry: it can lead to a significant increase of the swimming speed (up to a factor of five), a similar decrease (also up to a factor of five) or it can have approximately no impact. Analysis of our data along with theoretical modeling shows that the influence of viscoelasticity on helical propulsion is controlled by a snowman-like effect, previously reported for dumbbell swimmers, wherein the front-back asymmetry of the swimmer leads to a non-Newtonian elastic force that can either favor or hinder locomotion.
Island identity in an age of ecology: rural land use and a lodge on Carmelo Point, Gambier Island, British Columbia
Creators: name: Higham, Kevin Craig
Publisher: name: University of British Columbia
Year: 2009

description: The thesis is intended to provide an alternative model for rural land use planning and environmental management. The project addresses the issue of settlement and development of sixteen hectares on Carmelo Point, Gambier Island. . The intent of the design is to initiate the development of the site within the determined development areas and to provide specific examples of integrating passive ecological technologies. Furthermore, the proposed development is to utilize the natural renewable energy systems while mamtaining the site's natural character and balance. The design program for the thesis is centred in and around a commons and is comprised of a lodge for cohabitation. The lodge is to include seven private chambers which share facilities in common. These facilities are the dining hall, sun rooms, washrooms, and the kitchen. The lodge is to incorporate a post and beam structure supporting a roof, which is used to catch and harvest rainwater. Additionally, the roof is designed to promote a stacking effect within the interior space. Once the harvested rainwater has been filtered and used, it is then treated via a garden solar aquatic septic system. The lodge is recognized as an initial incremental step in developing the site for human settlement. This project is intended as a prototypical ecologically sensitive intervention in a rural landscape which is experiencing development pressures due to its proximity to the Vancouver metropolitan area.

description: Nonradiative processes limit optoelectronic functionality of nanocrystals and curb their device performance. Nevertheless, the dynamic structural origins of nonradiative relaxations in nanocrystals are not understood. Here, femtosecond electron diffraction measurements corroborated by atomistic simulations uncover transient lattice deformations accompanying radiationless electronic processes in semiconductor nanocrystals. Investigation of the excitation energy dependence shows that hot carriers created by a photon energy considerably larger than the bandgap induce structural distortions at nanocrystal surfaces on few picosecond timescales associated with the localization of trapped holes. On the other hand, carriers created by a photon energy close to the bandgap result in transient lattice heating that occurs on a much longer 200 ps timescale, governed by an Auger heating mechanism. Elucidation of the structural deformations associated with the surface trapping of hot holes provides atomic-scale insights into the mechanisms deteriorating optoelectronic performance and a pathway towards minimizing these losses in nanocrystal devices.

description: Alignment algorithms usually rely on simplified models of gaps for computational efficiency. Based on an isomorphism between alignments and physical helix-coil models, we show in statistical mechanics that alignments with realistic laws for gaps can be computed with fast algorithms. Improved performances of probabilistic alignments with realistic models of gaps are illustrated. Probabilistic and optimization formulations are compared, with potential implications in many fields and perspectives for computationally efficient extensions to Markov models with realistic long-range interactions.

description: Triangular transactions are an extremely common practice of trade both in the domestic and intra-community, and international trade, which has, however, been associated over the past years with the most provocative and large tax delinquency cases, attracting the interest of both public opinion and the political power, in an attempt to tackle the phenomenon of rampant tax evasion and avoidance, which deeply affects and injures the coveted financial balance of our country. The purpose of this study is to attempt to approach and study the basic traits of the commercial practice of triangular trade in the light mainly of its use as a tax dodge to serve the goal of reducing the tax liability or even total avoidance of tax payment under the intra-community and international trade. Particular attention is given to tax avoidance by the method of triangular transactions, as there lies the most extensive form of tax delinquency, and at the same time to present the tools applied to address this phenomenon, both from the perspective of the EU and of International Law, and the Greek Tax Law.

description: We study the one-loop anomalous dimensions of operators in the ${\cal N}=4$ super Yang-Mills theory that are dual to open strings ending on giant gravitons. We consider both AdS and sphere giants as well as boundstates of them. The open strings we consider carry angular momentum on an S^3 embedded in the S^5 of the AdS$_5\times$S^5 background. The main result of this article is that we derive a bosonic lattice Hamiltonian that describes the one loop mixing of the operators dual to the general excited giant graviton system. A semiclassical analysis of the Hamiltonian allows us to give a geometrical interpretation for the labeling used to describe the gauge theory operators. We also argue that AdS giant gravitons are unstable against the excitations considered.

description: Isotopic effects are relevant to understand several properties of solids, and have been thoroughly analyzed along the years. These effects may depend on the dimensionality of the considered solid. Here we assess their magnitude for structural properties of graphene, a paradigmatic two-dimensional material. We use path-integral molecular dynamics simulations, a well-suited technique to quantify the influence of nuclear quantum effects on equilibrium variables, especially in cases where anharmonic effects are important. Emphasis is put on interatomic distances and mean-square displacements, as well as on the in-plane area of the graphene layer. At low temperature, the relative difference in C--C distance for $^{13}$C and $^{14}$C, with respect to $^{12}$C, is found to be $-2.5$ and $-4.6 \times 10^{-4}$, respectively, larger than in three-dimensional carbon-based materials such as diamond. For the in-plane area, the relative changes amount to $-3.9$ and $-6.9 \times 10^{-4}$. The magnitude of anharmonicity in the lattice vibrations is estimated by comparing the internal energy and atomic vibrational amplitudes with those derived from a harmonic approximation.
