description: Achieving electrostatic control of quantum phases is at the frontier of condensed matter research. Recent investigations have revealed superconductivity tunable by electrostatic doping in twisted graphene heterostructures and in two-dimensional (2D) semimetals such as WTe$_2$. Some of these systems have a polar crystal structure that gives rise to ferroelectricity, in which the interlayer polarization exhibits bistability driven by external electric fields. Here we show that bilayer $T_d$-MoTe$_2$ simultaneously exhibits ferroelectric switching and superconductivity. Remarkably, a field-driven, first-order superconductor-to-normal transition is observed at its ferroelectric transition. Bilayer $T_d$-MoTe$_2$ also has a maximum in its superconducting transition temperature ($T_\textrm{c}$) as a function of carrier density and temperature, allowing independent control of the superconducting state as a function of both doping and polarization. We find that the maximum $T_\textrm{c}$ is concomitant with compensated electron and hole carrier densities and vanishes when one of the Fermi pockets disappears with doping. We argue that this unusual polarization-sensitive 2D superconductor is driven by an interband pairing interaction associated with nearly nested electron and hole Fermi pockets.

description: Monolithic 3D (M3D) integration has emerged as an enabling technology to design high performance and energy-efficient circuits and systems. The smaller dimension of vertical monolithic inter-tier vias (MIVs) lowers effective wirelength and allows high integration density. To design an energy-efficient many-core architecture, necessitates efficient resource management of the full SOC system, in terms of power and performance of the system. Voltage/frequency island (VFI)-based power management is a popular methodology for designing energy-efficient manycore architectures without incurring significant performance overhead. In an M3D chip, the vertical layers introduce inter-tier process variations that affect the performance of transistors and interconnects in different layers. Therefore, VFI-based power management in M3D manycore systems requires the consideration of inter-tier process variation effects. In this dissertation, we undertake the problem of resource management in M3D many-core architectures degraded due to inter-tier process variation effects inherent in M3D chips. Firstly, we present the design of an imitation learning (IL)-enabled VFI-based power management strategy that considers the inter-tier process-variation effects in M3D manycore chips. We demonstrate that the IL-based power management strategy can be fine-tuned based on the M3D characteristics. Our policy generates suitable V/F levels based on the computation and communication characteristics of the system for both process-oblivious and process-aware configurations. Subsequently, we propose a machine learning-based online update strategy of IL-based DVFI policies for process degraded M3D architectures. We demonstrate that with no prior knowledge of process-variation parameters, our online strategy captures the inter-tier process variations in the M3D system improving the power-performance trade-off than a process-oblivious offline DVFI policy for the degraded M3D many-core architecture. Furthermore, we show that online update strategy improves the overall energy-efficiency for unseen workloads that are not considered during offline DVFI policy creation.

description: We report an experimental noise study of intermediate sized quasi ballistic semiconducting multiwalled carbon nanotube (IS-MWCNT) devices. The noise is two orders of magnitude lower than in singlewalled nanotubes (SWCNTs) and has no length dependence within the studied range. In these channel limited devices with small or negligible Schottky barriers the noise is shown to originate from the intrinsic potential fluctuations of charge traps in the gate dielectric. The gate dependence of normalized noise can be explained better using ballistic the charge noise model rather than diffusive McWhorter model. The results indicate that the noise properties of IS-MWCNTs are closer to SWCNTs than thicker MWCNTs. These results can be utilized in future to analyze noise in other purely ballistic nanoscale devices.

Building Materials Genome from Ground-State Configuration to Engineering Advance

description: Individual phases are commonly considered as the building blocks of materials. However, the accurate theoretical prediction of properties of individual phases remains elusive. The top-down approach by decoding genomic building blocks of individual phases from experimental observations is non-unique. The density functional theory (DFT), as the state-of-the-art solution of quantum mechanics, prescribes the existence of a ground-state configuration at zero K for a given system. It is self-evident that the ground-state configuration alone is insufficient to describe a phase at finite temperatures as symmetry-breaking non-ground-state configurations are excited statistically at temperatures above zero K. Our multi-scale entropy approach (recently terms as Zentropy theory) postulates that the entropy of a phase is composed of the sum of the entropy of each configuration weighted by its probability plus the configurational entropy among all configurations. Consequently, the partition function of each configuration in statistical mechanics needs to be evaluated by its free energy rather than total energy. The combination of the ground- and non-ground-state configurations represents the building blocks of materials and can quantitively predict free energy of individual phases with the free energies of ground- and non-ground-state configurations predicted from DFT, plus all properties derived from free energy of individual phases.

description: The objective of this study was to find optimal freeze-drying process parameters to design porous and friable freeze-dried bismuth-potassium-ammonium citrate (FD BPAC) with improved dissolution behavior. The nucleation and melting temperatures of frozen BPAC solution in water and tert-butanol/water co-solvent system were studied with use of thermal analysis. The phases that resulted on cooling were studied by low-temperature powder x-ray diffraction. BPAC formed an amorphous freeze concentrate on cooling and remained amorphous during freeze-drying and subsequent storage. The nucleation of colloidal bismuth subcitrate (CBS) in the FD BPAC and starting BPAC systems in 0.1 M and 0.01 M HCl was studied by dynamic light scattering (DLS) method. The proposed preparation method of FD BPAC can be the basis for design of formulations with enhanced dissolution rate for bismuth-based triple/quadruple therapy, where FD BPAC simultaneously act as a carrier and an active ingredient.

description: We successively pass two $V$-type three-level atoms through a single-mode cavity field. Considering the field to be initially in a classical state, we evaluate various statistical properties such as the quasiprobability $Q$ function, Wigner distribution, Mandel's $Q$ parameter and normal squeezing of the resulted field. We notice that the sequential crossing of atoms induces nonclassicality into the character of a pure classical state (coherent field). The initial thermal field shows sub-Poissonian as well as squeezing property after interacting with the $V$ atoms.

Biodiversity
Spatio-Temporal Data Analytics

description: In the biodiversity domain, researchers often have to combine a large variety of heterogeneous spatio-temporal data sources. For example, the loss of biodiversity can be quantified by analyzing occurrence observations of various species across time. To find the root cause of that loss, occurrence data may need to be combined with satellite images to find possible correlations with climate variables. To facilitate an exploratory approach for this combination of data sources, it is essential to provide researchers with workflow-based tools such that each step during the formulation of a research hypothesis can be tracked. In this presentation, we will discuss Geo Engine, a workflow-based analysis platform for spatio-temporal data analytics, and its place within FAIR data spaces.

description: Experimental data at RHIC and SPS energies suggest a systematic correlation between yield ratio $\bar{p}/p$ and $K^{-}/K^{+}$, which reveal some universality of hadron production in relativistic heavy ion collisions. We propose an explanation based on the quark combination mechanism in which the production asymmetry between baryons and antibaryons is focused on especially. We start from the basic ideas of quark combination to carry out a general analysis of the properties of the global production of baryons and mesons and obtain the yields of baryons, antibaryons and mesons as functions of the number of constituent quarks and antiquarks just before hadronization. In particular, we study effects of quark-antiquark asymmetry on the ratio of (anti-)baryons to mesons and that of antibaryons to baryons. We use these formula to well explain the data of $\bar{p}/p$ and $K^{-}/K^{+}$ at different of collision energies and rapidities and suggest further measurements at moderate RHIC energies in the mid-forward rapidity regions to make the decisive test of this universality.

description: We present results on numerical calculations of the sensitivity coefficients, Qmu, of microwave molecular transitions in (13C)H3OH and CH3(18O)H to the hypothetical variation in the fundamental physical constant mu - the electron-to-proton mass ratio. The invariability of mu in time and space is one of the basic assumptions of the Standard Model of particle physics which can be tested at cosmological scales by means of astronomical observations in the Galaxy and external galaxies. Our calculations show that these two methanol isotopologues can be utilized for such tests since their microwave transitions from the frequency interval 1-100 GHz exhibit a large spread in Qmu values which span a range of -109 < Qmu < 78. We show that the thermal emission lines of (13C)H3OH observed in the star-forming region NGC6334I constrain the variability of mu at a level of 3x10^-8 (1σ), which is in line with the most stringent upper limits obtained previously from observations of methanol (CH3OH) and other molecules in the Galaxy.

description: The bacterial strains Rhodococcus sp. S, Pseudomonas sp. S and Consortium M isolated from hydrocarbon contaminated sites in Skikda (Algeria) and Alexandria (Egypt) were tested for their ability to bioremediate crude oil contaminated sea water in lab microcosms. Different treatments including bioaugmentation, biostimulation and attenuation were tested. Ammonium nitrate was used as nitrogen source. Dissodium hydrogen phosphate and sodium dihydrogen phosphate were used as phosphorus sources. After six weeks crude oil degradation was between 70.5 and 95% except in the attenuation treatment (55.5%). The wheat straw immobilized cells enhanced crude oil degradation in comparison with free cells. The immobilized cells of Rhodococcus sp. S and Consortium M could degrade 88 and 91% respectively from 3% of crude oil in presence of Triton X-100 after four weeks. In absence of Triton X-100 they could degrade 89.5 and 90% respectively. The scale-up of lab microcosms revealed that the best results were obtained in bioaugmentation with immobilized cells of Consortium M. The increase in biodegradation of crude oil was correlated with an increase in dehydrogenase activity. The effect of crude oil toxicity was evaluated using local marine algae. The results revealed that bioremediated sea water had less toxicity in comparison with untreated one.

Ιδανική λύση στο ζήτημα των μεταφορών αποτελούν τα ηλεκτρικά οχήματα. Παράλληλα με τα οικονομικά και τα περιβαλλοντικά οφέλη που προσφέρουν τα ηλεκτρικά οχήματα, η μαζική παραγωγή τους μπορεί να τροποποιήσει σημαντικά το προφίλ της ζήτησης των δικτύων διανομής. Το γεγονός αυτό αναμφισβήτητα μπορεί να προκαλέσει επιβάρυνση στη ομαλή λειτουργία του δικτύου, όπως διακυμάνσεις της τάσης, υπερφορτίσεις του δικτύου κ.α.
Προκειμένου να αποφευχθούν αυτά τα θέματα, είναι απαραίτητο να εφαρμοστεί ένα μοντέλο ενεργειακής διαχείρισης της φόρτισης των ηλεκτρικών οχημάτων. Σκοπός της παρούσας διπλωματικής είναι η ανάπτυξη ενός συστήματος ελέγχου φόρτισης που ως στόχο έχει την ικανοποίηση των αναγκών φόρτισης των χρηστών των ηλεκτρικών οχημάτων χωρίς να παραβιάζονται ταυτόχρονα οι τεχνικοί περιορισμοί του δικτύου.

• Μη ελεγχόμενη Φόρτιση (Dumb Charging)
• Ελεγχόμενη Φόρτιση (Smart Charging)
Βασικά κριτήρια σύμφωνα με τα οποία αναπτύχθηκε το συγκεκριμένο σύστημα ελέγχου αποτέλεσαν:
• Διακύμανση της τάσης των ζυγών του δικτύου σε όρια τα οποία θέτει ο διαχειριστής.
• Ελαχιστοποίηση των απωλειών του δικτύου.
• Ελαχιστοποίηση του κόστους φόρτισης των οχημάτων σύμφωνα με την τιμή της ηλεκτρικής ενέργειας κάθε χρονική στιγμή.

description: The goal of this thesis was to implement an ARM processor with Single Instruction Multiple Data (SIMD) extensions using the Bluespec System Verilog (BSV) as a Hardware Description Language (HDL). BSV has a fundamentally different approach to hardware design, comparing to other HDLs. It is based on circuit generation - rather than merely circuit description - and on atomic transactional rules instead of a globally synchronous view of the world. BSV language is considered a high-level functional HDL, which was essentially Haskell - extended to handle chip design and electronic design automation in general. BSV is partially evaluated (to convert the Haskell parts) and compiled to the Term Rewriting System (TRS). Our scalar processor supports a 3-stage pipeline (Fetch – Decode – Execute), belongs to the ARM7 family and uses a 32-bit architecture, which is based on ARMv4 instruction set. The SIMD unit works as an extension to the scalar part and is based on a modification of ARM NEON technology. The scalar part of the processor supports Data processing, Multiply, Long Multiply, Load/Store – Byte/Word and Branch instructions of the ARM Instruction Set Format, while the vector part supports Vector Data Processing, Vector Multiply and Vector Load/Store instructions.

description: We propose a model of a confining dark sector, dark technicolor, that communicates with the Standard Model through the Higgs portal. In this model electroweak symmetry breaking and dark matter share a common origin, and the electroweak scale is generated dynamically. Our motivation to suggest this model is the absense of evidence for new physics from recent LHC data. Although the conclusion is far from certain at this point, this lack of evidence may suggest that no mechanism exists at the electroweak scale to stabilise the Higgs mass against radiative corrections from UV physics. The usual reaction to this puzzling situation is to conclude that the stabilising new physics is either hidden from us by accident, or that it appears at energies that are currently inaccessible, such that nature is indeed fine-tuned. In order to re-examine the arguments that have lead to this dichotomy, we review the concept of naturalness in effective field theories, discussing in particular the role of quadratic divergences in relation to different energy scales. This leads us to suggest classical scale invariance as a guidline for model building, implying that explicit mass scales are absent in the underlying theory.

description: This paper examines how MNEs operating within the International Product Cycle and an Improving Value-Added Chain between and within countries and industries can feel compelled by competitive pressures to expand globally through sales and FDI into emerging markets in order to find market growth and/or lower costs and then be trapped by graft and corruption and the risks associated with the US Foreign Corrupt Practices Act or similar statutes in other OECD countries. It also explains how herding, global competition and instant communication can create Financial Bubbles that amplify and exacerbate the existing corruption. It then offers MNE executives some possible approaches for identifying and managing corruption pressures including factor reversal and on-shoring strategies.

description: Performers' copies of musical scores are typically rich in handwritten annotations, which capture historical and institutional performance practices. The development of rich, interactive interfaces to explore digital archives of these scores and the systematic investigation of their meaning and function will be facilitated by the automatic extraction of handwritten score annotations. We present several approaches to the extraction of handwritten annotations of arbitrary content from digitized images of musical scores. First, we show promising results in certain contexts when using simple unsupervised clustering techniques to identify handwritten annotations in conductors' scores. Next, we compare annotated scores to unannotated copies and use a printed sheet music comparison tool, Aruspix, to recover handwritten annotations as additions to the clean copy. Using both of these techniques in a combined annotation pipeline qualitatively improves the recovery of handwritten annotations. Recent work has shown the effectiveness of reframing classical optical musical recognition tasks as supervised machine learning classification tasks. In the same spirit, we pose the problem of handwritten annotation extraction as a supervised pixel classification task, where the feature space for the learning task is derived from the intensities of neighboring pixels. After an initial investment of time required to develop dependable training data, this approach can reliably extract annotations for entire volumes of score images without further supervision. These techniques are demonstrated using a sample of orchestral scores annotated by professional conductors of the New York Philharmonic Orchestra. Handwritten annotation extraction in musical scores has applications to the systematic investigation of score annotation practices by performers, annotator attribution, and to the interactive presentation of annotated scores, which we briefly discuss.

description: The role of uncertainty in data management has become more prominent than ever before, especially because of the growing importance of machine learning-driven applications that produce large uncertain databases. A well-known approach to querying such databases is to blend rule-based reasoning with uncertainty. However, techniques proposed so far struggle with large databases. In this paper, we address this problem by presenting a new technique for probabilistic reasoning that exploits Trigger Graphs (TGs) -- a notion recently introduced for the non-probabilistic setting. The intuition is that TGs can effectively store a probabilistic model by avoiding an explicit materialization of the lineage and by grouping together similar derivations of the same fact. Firstly, we show how TGs can be adapted to support the possible world semantics. Then, we describe techniques for efficiently computing a probabilistic model, and formally establish the correctness of our approach. We also present an extensive empirical evaluation using a prototype called LTGs. Our comparison against other leading engines shows that LTGs is not only faster, even against approximate reasoning techniques, but can also reason over probabilistic databases that existing engines cannot scale to.

title: Automatic coastline extraction from aerial images using edge detection and optimization procedures

description: Nowadays, coastline detection and formation monitoring has become of high importance due to the increasing effects of climate change, global warming and rapid growth of human population on the morphological characteristics of coasts. Coastal areas play a significant role on the economy of an entire region especially in major tourist destinations, where tourist infrastructure has been developed in the last decades. This thesis addresses the problem of coastline extraction and morphological change monitoring/tracking in the course of decades. The proposed methodology presents an automatic coastline extraction algorithm, which utilizes grayscale aerial images. Our method is summarized in a four-step algorithm that enables robust extraction of the coastline. Specifically, the first step of our approach is a noise distortion reduction stage with the goal of ameliorating its impact on the input data. The subsequent step involves the application of a local threshold in the input image to segment it into a binary class image, land and sea. The result is then passed to the third stage of our approach, which applies morphological operators on the binary image, with the aim of removing small objects and preserving only the objects of interest. Finally in the last stage of our method, we perform edge detection and active contours fitting, in order to extract and model the coastline. The aforementioned algorithmic steps are illustrated through examples, which demonstrate the efficacy of the proposed methodology. The algorithm is also applicable to one band satellite imagery due to the fact they have same characteristics with grayscale aerial images.

description: We show that there exist Gaussian channels which are amendable. A channel is amendable if when applied twice is entanglement breaking while there exists a unitary filter such that, when interposed between the first and second action of the map, prevents the global transformation from being entanglement breaking [Phys. Rev. A 86, 052302 (2012)]. We find that, depending on the structure of the channel, the unitary filter can be a squeezing transformation or a phase shift operation. We also propose two realistic quantum optics experiments where the amendability of Gaussian channels can be verified by exploiting the fact that it is sufficient to test the entanglement breaking properties of two mode Gaussian channels on input states with finite energy (which are not maximally entangled).

description: GPU-embedded systems have gained popularity across various domains due to their efficient power consumption. However, in order to meet the demands of real-time or time-consuming applications running on these systems, it is crucial for them to be tuned to exhibit high performance. This paper addresses the issue by developing and comparing two tuning methodologies on GPU-embedded systems, and also provides performance insights for developers and researchers seeking to optimize applications running on these architectures. We focus on parallel prefix operations, such as FFT, scan primitives, and tridiagonal system solvers, which are performance-critical components in many applications. The study introduces an analytical model-driven tuning methodology and a Machine Learning (ML)-based tuning methodology. We evaluate the performance of the two tuning methodologies for different parallel prefix implementations of the BPLG library in an NVIDIA Jetson system, and compare their performance to the ones achieved through an exhaustive search. The findings shed light on the best strategies for handling the open challenge of performance portability for major computational patterns among server and embedded devices, providing practical guidance for offline and online tuning. We also address the existing gap in performance studies for parallel computational patterns in GPU-embedded systems by comparing the BPLG performance against other state-of-the-art libraries, including CUSPARSE, CUB, and CUFFT.

description: The synthesis of a mesoporous pseudoboehmite without the use of organic agents is defined in this study. Precipitation at pH=7 and at atmospheric pressure of a temperature solution of 60°C, alkaline melting of a bauxite, gave a mesoporous pseudoboehmite with a specific surface area of 317 m2/g. As a precipitating agent, hydrochloric acid (HCl) is used. In comparison, applying the same treatment to the same solution but at a lower temperature of 25°C resulted in an amorphous gel with a low specific surface. As a result, the temperature of the synthesis solution has a big impact on the textural properties of the finished product, particularly the volume and pore diameter. As a result, compared to pseudoboehmite, the amorphous gel has a lower pore volume and a larger average pore diameter. Furthermore, using this simple process, the pseudoboehmite was transformed into a nano spinel lattice alumina-γ with a precise surface area of 272 m2/g. The topotactic properties of pseudoboehmite were almost preserved in the textural analysis of alumina. To characterise the synthesised materials, EDX, XRD, FTIR, SEM, and BET were used as analytical methods. The nitrogen isotherms and pore size distribution curves confirm that the products made at 25°C or 60°C with alumina-γ are mesoporous materials with flat particles.

description: Reaction networks are systems in which the populations of a finite number of species evolve through predefined interactions. Such networks are found as modeling tools in many biological disciplines such as biochemistry, ecology, epidemiology, immunology, systems biology and synthetic biology. It is now well-established that, for small population sizes, stochastic models for biochemical reaction networks are necessary to capture randomness in the interactions. The tools for analyzing such models, however, still lag far behind their deterministic counterparts. In this paper, we bridge this gap by developing a constructive framework for examining the long-term behavior and stability properties of the reaction dynamics in a stochastic setting. In particular, we address the problems of determining ergodicity of the reaction dynamics, which is analogous to having a globally attracting fixed point for deterministic dynamics. We also examine when the statistical moments of the underlying process remain bounded with time and when they converge to their steady state values. The framework we develop relies on a blend of ideas from probability theory, linear algebra and optimization theory. We demonstrate that the stability properties of a wide class of biological networks can be assessed from our sufficient theoretical conditions that can be recast as efficient and scalable linear programs, well-known for their tractability. It is notably shown that the computational complexity is often linear in the number of species. We illustrate the validity, the efficiency and the wide applicability of our results on several reaction networks arising in biochemistry, systems biology, epidemiology and ecology. The biological implications of the results as well as an example of a non-ergodic biological network are also discussed.

description: Σε μια πόλη σαν την Χαλκίδα, όπου η οικιστική κληρονομιά υπέστη αρκετές απώλειες με την πάροδο του χρόνου και κτίρια χαρακτηριστικής αρχιτεκτονικής κατεδαφίστηκαν, η εικόνα της είναι η επικρατούσα κάθε ελληνικής πόλης.  Πολυόροφες πολυκατοικίες ανάμεσα σε κτίρια που χάνονται στην οικονομική και οικοδομική εντροπία και απουσία βιώσιμου δημόσιου χώρου.   Σε αυτά συμπεριλαμβάνονται οικοδομήματα της  βιομηχανικής κληρονομιάς που άφησε στη Χαλκίδα, μία εποχή κατά την οποία η οικονομική ακμή είχε φτάσει σε υψηλά επίπεδα. Τέτοια κτίρια συναντώται σε όλη την έκταση της πόλης, τα οποία στέκονται στο χώρο χωρίς χρήση, αυτοαναφερόμενα, θυμίζοντας απροσέγγιστα φρούρια.  Υπό αυτό το πρίσμα, στη συγκεκριμένη διπλωματική εργασία γίνεται μία προσπάθεια επαναδιαπραγμάτευσης του δημόσιου χώρου της πόλης μέσω της αξιοποίησης των βιομηχανικών της κελυφών.

Σε δεύτερη φάση, η εργασία εστιάζει στον τελευταιο σταθμό πριν το σημείο εκτόνωσης (Δημοτική Αγορά) του δικτύου αυτού, το «Μακαρονάδικο». Προτείνεται η αποκατάσταση του πρώην εργοστασίου Μακαρονοποιϊας, επανάχρηση του και μετατροπή αυτού σε Σχολή Μουσικoλογίας και Οργανοποϊας με συναφείς χρήσεις και διαμόρφωση δημόσιου χώρου.

description: This article presents the solution of the fractional SIR epidemic model using the Laplace residual power series method. We introduce the fractional SIR model in the sense of Caputo's derivative, it is presented by three fractional differential equations, in which the third one depends on the first coupled equations. The Laplace residual power series method is implemented in this research to solve the proposed model, in which we present the solution in a form of convergent series expansion that converges rapidly to the exact one. We analyze the results and compare the obtained approximate solutions to those obtained from other methods. Figures and tables are illustrated to show the efficiency of the LRPSM in handling the proposed SIR model.
Translation-invariant relativistic Langevin equation derived from first principles

description: The relativistic Langevin equation poses a number of technical and conceptual problems related to its derivation and underlying physical assumptions. Recently, a method has been proposed in [A. Petrosyan and A. Zaccone, J. Phys. A: Math. Theor. 55 015001 (2022)] to derive the relativistic Langevin equation from a first-principles particle-bath Lagrangian. As a result of the particle-bath coupling, a new ``restoring force'' term appeared, which breaks translation symmetry. Here we revisit this problem aiming at deriving a fully translation-invariant relativistic Langevin equation. We successfully do this by adopting the renormalization potential protocol originally suggested by Caldeira and Leggett. The relativistic renormalization potential is derived here and shown to reduce to Caldeira and Leggett's form in the non-relativistic limit. The introduction of this renormalization potential successfully removes the restoring force and a fully translation-invariant relativistic Langevin equation is derived for the first time. The physically necessary character of the renormalization potential is discussed in analogy with non-relativistic systems, where it emerges due to the renormalization of the tagged particle dynamics due to its interaction with the bath oscillators (a phenomenon akin to level-repulsion or avoided-crossing in condensed matter). We discuss the properties that the corresponding non-Markovian friction kernel has to satisfy, with implications ranging from transport models of the quark-gluon plasma, to relativistic viscous hydrodynamic simulations, and to electrons in graphene.
