description: Boundary conditions for the two-dimensional fermions in ribbons of the hexagonal lattice are studied in the dice model whose energy spectrum in infinite system consists of three bands with one completely flat band of zero energy. Like in graphene the regular lattice terminations are of the armchair and zigzag types. However, there are four possible zigzag edge terminations in contrast to graphene where only one type of zigzag termination is possible. Determining the boundary conditions for these lattice terminations, the energy spectra of pseudospin-1 fermions in dice model ribbons with zigzag and armchair boundary conditions are found. It is shown that the energy levels for armchair ribbons display the same features as in graphene except the zero energy flat band inherent to the dice model. In addition, unlike graphene, there are no propagating edge states localized at zigzag boundary and there are specific zigzag terminations which give rise to bulk modes of a metallic type in dice model ribbons. We find that the existence of the flat zero-energy band in the dice model is very robust and is not affected by the zigzag and armchair boundaries.

description: Polar Connect will be an unprecedented long-haul fiber optic link going through the Arctic from Europe to Asia. Today, it is possible to use fiber optic cables for sensing in addition to telecommunication. Since the Arctic Ocean is relatively unexplored due to its remoteness and extreme climate, and since studying the Arctic Ocean is important within climate research, applying fiber optic sensing on Polar Connect is a unique and unprecedented opportunity. Having reliable and continuous measurements in the Arctic is highly wished by scientists on Arctic research.

In this deliverable, a feasibility study on sensing applications of subsea fiber optic cables is provided. The study is based on input from a submarine cable vendor, general research literature, other similar sensing projects and consultations with relevant researchers and companies. 

In the deliverable the following is investigated:

Which fiber sensing technologies are relevant to Polar Connect and for Artic cable systems in general?

What applications do current fiber sensing technologies offer?

What future applications are requested by Arctic scientists?

The feasibility of meeting the requests of the scientists by the capabilities of fiber optic sensors.

description: We investigated the optical properties of (Ca,Sr)RuO_3 films on the borderline of a metal-insulator (M-I) transition. Our results show all of the predicted characteristics for a metallic Mott-Hubbard system, including (i) a mass enhancement in dc-limit, (ii) an U/2 excitation, and (iii) an U excitation. Also, a self-consistency is found within the Gutzwiller-Brinkman-Rice picture for the Mott transition. Our finding displays that electron correlation should be important even in 4d materials.

description: Understanding of the structure of turbulent flows at extreme Reynolds numbers (Re) is relevant because of several reasons: almost all turbulence theories are only valid in the high Re limit, and most turbulent flows of practical relevance are characterized by very high Re. Specific questions about wall-bounded turbulent flows at extreme Re concern the asymptotic laws of the mean velocity and turbulence statistics, their universality, the convergence of statistics towards their asymptotic profiles, and the overall physical flow organization. In extension of recent studies focusing on the mean flow at moderate and relatively high Re, the latter questions are addressed with respect to three canonical wall-bounded flows (channel flow, pipe flow, and the zero-pressure gradient turbulent boundary layer). Main results reported here are the asymptotic logarithmic law for the mean velocity and corresponding scale-separation laws for bulk flow properties, the Reynolds shear stress, the turbulence production and turbulent viscosity. A scaling analysis indicates that the establishment of a self-similar turbulence state is the condition for the development of a strict logarithmic velocity profile. The resulting overall physical flow structure at extreme Re is discussed.

description: We studied three conserved ciliary proteins, FAP256/CEP104, CHE12/Crescerin and ARMC9, in the ciliate Tetrahymena. Using a combination of super-resolution structural illumination and electron microscopy we show that these proteins localize near the plus ends of ciliary microtubules where they control their length and subsequently the structural organization of ciliary ends. Our results show that defects in the geometry of ciliary ends affect the function of cilia.

description: The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. It is argued that essentially all inflationary models lead to (future-)eternal inflation, which implies that an infinite number of pocket universes are produced. Although the other pocket universes are unobservable, their existence nonetheless has consequences for the way that we evaluate theories and extract consequences from them. The question of whether the universe had a beginning is discussed but not definitively answered. It appears likely, however, that eternally inflating universes do require a beginning.

description: A shapeable planar Hall sensor has been fabricated by lift-off a bilayer structure of NiFe(10 nm)/IrMn (8 nm) grown on a Kapton/PDMS substrate without using a buffer layer. The sensor exhibits a magnetic field sensitivity of 0.74 $μ$V/Oe.mA and provides a stable response under repetitive ON/OFF experiments. The concave and convex bending measurements indicate that the AMR voltage of the sensor is very sensitive to the stress and strain. However, the planar Hall sensitivity is independent from them with a stable linear region and unchanged peak positions in the magnetic field axis. This type of behaviour has been observed for the first time in the planar Hall sensors. Therefore, this novel device can fulfill simultaneous multifunctional sensing of small magnetic fields, stress and strain. This makes it promising for tactile sensing applications in humanoid robotics.

description: Genus Sciurella Allman, 1883
 Type species. Sciurella indivisa Allman, 1883, by monotypy.
 Diagnosis. Colonies erect, composed of multiple stems springing in clusters from the hydrorhiza. Stems thick but monosiphonic, either simple or forked, divided into somewhat regular internodes; coenosarc canaliculate. Stem internodes usually bearing four cladial apophyses, of which a pair is set close to the proximal node, while the other is found next to the distal node, the pairs forming an acute angle between them and giving the hydrocladia a bipinnate arrangement along the stem; the number of cladia per internode and their arrangement could be locally or fully altered, giving rise to stems whose appearances range from simple-pinnate to multi-verticillate. Cladial apophyses stubby, bearing a prominent adaxial mamelon, and a number of flanking nematothecae. Cladia unbranched, divided into elongate internodes, composed of usually one hydrotheca (but up to three possibly present) and its complement of three nematothecae. Hydrotheca long, almost tubular, fully adnate, with thick perisarc. Mesial nematotheca quite long, conical, borne on a distinct bulge of perisarc far below the hydrothecal base; lateral nematothecae comparatively shorter, sometimes becoming almost globular; all nematothecae bithalamic, wall of upper chamber with deep adaxial emargination. Gonothecae borne in pairs, one to each side of the cladial apophyses; gonothecae not known in all species but, when present, either stellate or urn-shaped, flattened dorso-ventrally and curving over the corresponding stem internode; as a rule, the gonothecae are provided with nematothecae (notably along their perimeter) whose coenosarc is composed of ramifications originating from a central blastostyle.
 Remarks. Morphologically, the genus Sciurella is readily distinguished from Nemertesia Lamouroux, 1812 through the following features: 1) unlike in Nemertesia, its cladia are borne at different levels on the stem internodes, often adopting a bipinnate arrangement; 2) its hydrothecae are very deep and almost tubular, instead of being cup-shaped; 3) its gonothecae are armed with nematothecae, instead of being devoid of them; 4) the upper chamber of all nematothecae is distinctly emarginated on the adaxial side, instead of having an entire rim.

description: Results on the correlations of low density classical and quantum Coulomb systems at equilibrium in three dimensions are reviewed. The exponential decay of particle correlations in the classical Coulomb system -- Debye-Hückel screening -- is compared and contrasted with the quantum case where strong arguments are presented for the absence of exponential screening. Results and techniques for detailed calculations that determine the asymptotic decay of correlations for quantum systems are discussed. Theorems on the existence of molecules in the Saha regime are reviewed. Finally, new combinatoric formulas for the coefficients of Mayer expansions are presented and their role in proofs of results on Debye-Hückel screening is discussed.

description: This dissertation investigates the cognitive field of the relations and the interactions between literature and journalism in Russia, in the context of the country's historical course from the 19th century to the present day (2024). In conducting this study, it was deemed appropriate to expand the time frame to the Middle Ages, where theroots of the peculiar Russian phenomenon of publitsistika, a term that marks the interpenetration of these two literary arts, were pinpointed. Based on the study of literary currents, journalistic genres, themes found in Russian periodicals,censorship regulations of the Russian state, criticism, competition between the two main literary parties (the admirers of Western civilization and the Slavophiles), as well as the content of the journals, research has led to an understanding of the universal value of Russian literature, which lies in Christian Realism, which expresses the temperament of the Russian people and constitutes its cohesive, cultural tradition.

description: To study the nanoscopic interaction between edge dislocations and a phase boundary within a two-phase microstructure the effect of the phase contrast on the internal stress field due to the dislocations needs to be taken into account. For this purpose a 2D semi-discrete model is proposed in this paper. It consists of two distinct phases, each with its specific material properties, separated by a fully coherent and non-damaging phase boundary. Each phase is modelled as a continuum enriched with a Peierls--Nabarro (PN) dislocation region, confining dislocation motion to a discrete plane, the glide plane. In this paper, a single glide plane perpendicular to and continuous across the phase boundary is considered. Along the glide plane bulk induced shear tractions are balanced by glide plane shear tractions based on the classical PN model. The model's ability to capture dislocation obstruction at phase boundaries, dislocation pile-ups and dislocation transmission is studied. Results show that the phase contrast in material properties (e.g. elastic stiffness, glide plane properties) alone creates a barrier to the motion of dislocations from a soft to a hard phase. The proposed model accounts for the interplay between dislocations, external boundaries and phase boundary and thus represents a suitable tool for studying edge dislocation--phase boundary interaction in two-phase microstructures.

description: The features of the ordinary least squares method, which gives a possible way to a solution of the overdetermined systems of algebraic equations and allows to estimate the uncertainties of the obtained solutions, are considered. As the important physical example we define four-loop QCD coefficients in the dependence of the relation between pole and running heavy quarks masses on the number of light flavors, using the existing results of numerical supercomputer based calculations of the corresponding four-loop contributions at different fixed numbers of light flavors. Stability of the found solutions to the number of the considered equations and unknowns is demonstrated and supported by the Pearsons's $χ$-squared test.

description: We study the connection between heat transport properties of systems coupled to different thermal baths in two separate regions and their underlying nonequilibrium dynamics. We consider classical systems of interacting particles that may exhibit a certain degree of delocalization, and whose effective dimensionality can be modified through the controlled variation of a global trapping potential. We focus on Coulomb crystals of trapped ions, which offer a versatile playground to shed light on the role that spatial constraints play on heat transport. We use a three-dimensional model to simulate the trapped ion system, and show in a numerically rigorous manner to what extent heat transport properties could be feasibly tuned across the structural phase transitions between the linear, planar zigzag and helical configurations. By solving the classical Langevin equations of motion, we analyze the steady state spatial distributions of the particles, the temperature profiles and total heat flux through the various structural phase transitions that the system may experience. The results evidence a clear correlation between the degree of delocalization of the internal ions and the emergence of a non-zero gradient in the temperature profiles. The signatures of the phase transitions in the total heat flux as well as the optimal spatial configuration for heat transport are shown.

Nonlinear analysis of the shearing instability in granular gases

description: It is known that a finite-size homogeneous granular fluid develops an hydrodynamic-like instability when dissipation crosses a threshold value. This instability is analyzed in terms of modified hydrodynamic equations: first, a source term is added to the energy equation which accounts for the energy dissipation at collisions and the phenomenological Fourier law is generalized according to previous results. Second, a rescaled time formalism is introduced that maps the homogeneous cooling state into a nonequilibrium steady state. A nonlinear stability analysis of the resulting equations is done which predicts the appearance of flow patterns. A stable modulation of density and temperature is produced that does not lead to clustering. Also a global decrease of the temperature is obtained, giving rise to a decrease of the collision frequency and dissipation rate. Good agreement with molecular dynamics simulations of inelastic hard disks is found for low dissipation.

 Remarks. The males from Qionglai have been identified as Togoperla sp. by the senior author and its mitogenomical results was analyzed by Wang et al. (2016). After we checked and compared with the holotype of T. grahami we believe that they are conspecific. The Sichuan materials have identical color pattern and external terminalia. However, the trilobed apex of aedeagal sac is more enlarged than that in holotype of T. grahami and the illustration in Stark & Sivec (2008: fig. 17), which may result from artificial eversion. The males from Qionglai also show a heavier hirsute areas of terga 6–8 and a distinct medial sclerite of tergum 9, together with darker habitus may indicate that these males are fully aged specimens.

description: In this second paper of the series on internal gravity waves (IGWs), we present a study of the generation and propagation of IGWs in a model solar atmosphere with diverse magnetic conditions. A magnetic field free, and three magnetic models that start with an initial, vertical, homogeneous field of 10 G, 50 G, and 100 G magnetic flux density, are simulated using the CO$^{\rm 5}$BOLD code. We find that the IGWs are generated in similar manner in all four models in spite of the differences in the magnetic environment. The mechanical energy carried by IGWs is significantly larger than that of the acoustic waves in the lower part of the atmosphere, making them an important component of the total wave energy budget. The mechanical energy flux (10$^{6}$ - 10$^{3}$ W m$^{-2}$) is few orders of magnitude larger than the Poynting flux (10$^{3}$ - 10$^{1}$ W m$^{-2}$). The Poynting fluxes show a downward component in the frequency range corresponding to the IGWs, which confirm that these waves do not propagate upwards in the atmosphere when the fields are predominantly vertical and strong. We conclude that, in the upper photosphere, the propagation properties of IGWs depend on the average magnetic field strength and therefore these waves can be potential candidate for magnetic field diagnostics of these layers. However, their subsequent coupling to Alfvénic waves are unlikely in a magnetic environment permeated with predominantly vertical fields and therefore they may not directly or indirectly contribute to the heating of layers above plasma-$β$ less than 1.

description: I review the black hole uniqueness theorem and the no hair theorems established for physical black hole stationary states by the early 80'. This review presents the original and decisive work of Carter, Robinson, Mazur and Bunting on the problem of no bifurcation and uniqueness of physical black holes. Its original version was written only few years after my proof of the Kerr-Newman et al. black hole uniqueness theorem has appeared in print. The proof of the black hole uniqueness theorem relies heavily on the positivity properties of nonlinear sigma models on the Riemannian noncompact symmetric spaces with negative sectional curvature. It is hoped that the first hand description of the original developments leading to our current understanding of the black hole uniqueness will be found useful to all interested in the subject.
description: 26 pages, Latex. I have reviewed here the classic by now developments in the mathematical theory of black holes which have led to the black hole uniqueness and the black hole no hair theorems

description: A summary of the work recently carried out on the morphotropic phase boundary (MPB) of PZT is presented. By means of x-ray powder diffraction on ceramic samples of excellent quality, the MPB has been successfully characterized by changing temperature in a series of closely spaced compositions. As a result, an unexpected monoclinic phase has been found to exist in between the well-known tetragonal and rhombohedral PZT phases. A detailed structural analysis, together with the investigation of the field effect in this region of compositions, have led to an important advance in understanding the mechanisms responsible for the physical properties of PZT as well as other piezoelectric materials with similar morphotropic phase boundaries.

description: Pulsed neutron diffraction investigations have been performed in the ferroelectric PZT system, Pb(Zr1-xTix)O3, doped with 1%wt. of Nb2O5, as a function of both temperature and composition. The study has been made in a wide range of temperatures encompassing the three known phases in Zr-rich PZT: ferroelectric low temperature (R3c), ferroelectric high temperature (R3m) and paraelectric (Pm3m). The combination of the temperature and the composition dependence of the structural parameters allowed the determination of the special relationship, recently pointed out by Corker et al., between the octahedral strain (z) and the tilt angle (w) in the ferroelectric low temperature phase (FL) of PZT. The strain-tilt coupling coefficient has been found to decrease linearly with Ti content and the composition at which z and w de-couple to be of x=0.30.

description: We first obtain the analogue of Vaidya's solution on the brane for studying the collapse of null fluid onto a flat Minkowski cavity on the brane. Since the back-reaction of the bulk onto the brane is supposed to strengthen gravity on the brane, it would favour formation of black hole as against naked singularity. That is the parameter window in the initial data set giving rise to naked singularity in the 4D Vaidya case would now get partially covered.

description: Neutron pair distribution function analysis and first principles calculations have been employed to study short-range correlations in heavily disordered dielectric material Sr$_x$Ba$_{1-x}$Nb$_2$O$_6$ ($x=0.35, 0.5$ and 0.61). The combination of methods has been fruitful in pinpointing main local-structure features, their temperature behaviour and interrelation. A rather complex system of tilts is found to be both temperature and Sr-content sensitive with the biggest tilt magnitudes reached at low temperatures and high $x$. Relative Nb-O$_6$ displacements, directly responsible for material's ferroelectric properties, are shown to be distinct in two octahedra sub-systems with different freezing temperatures and disparate levels of deviation from macroscopic polarization direction. Intrinsic disorder caused by Sr, Ba and vacancy distribution is found to introduce local strain to the structure and directly influence octahedra tilting. These findings establish a new atomistic picture of the local structure -- property relationship in Sr$_x$Ba$_{1-x}$Nb$_2$O$_6$.

description: We use a Monte Carlo bond-switching method to study systematically the thermodynamic properties of a "continuous random network" model, the canonical model for such amorphous systems as a-Si and a-SiO$_2$. Simulations show first-order "melting" into an amorphous state, and clear evidence for a glass transition in the supercooled liquid. The random-network model is also extended to study heterogeneous structures, such as the interface between amorphous and crystalline Si.

Does Giant Magnetoresistance Survive in Presence of Superconducting Contact?

description: The giant magnetoresistance (GMR) of ferromagnetic bilayers with a superconducting contact (F1/F2/S) is calculated in ballistic and diffusive regimes. As in spin-valve, it is assumed that the magnetization in the two ferromagnetic layers F1 and F2 can be changed from parallel to antiparallel. It is shown that the GMR defined as the change of conductance between the two magnetic configurations is an oscillatory function of the thickness of F2 layer and tends to an asymptotic positive value at large thickness. This is due to the formation of quantum well states in F2 induced by Andreev reflection at the F2/S interface and reflection at F1/F2 interface in antiparallel configuration. In the diffusive regime, if only spin-dependent scattering rates in the magnetic layers are considered (no difference in Fermi wave-vectors between spin up and down electrons) then the GMR is supressed due to the mixing of spin up and down electron-hole channels by Andreev reflection.

By means of the replica approach, translating the problem in the study of a molecular liquid, we study the phase transition due to the entropy crisis and we find that the Kauzmann's temperature $\tk$ is $\sim 0.32$. At the end we compare analytical predictions with numerical results.

description: A quantum computer (QC) can solve many computational problems more efficiently than a classic one. The field of QCs is growing: companies (such as DWave, IBM, Google, and Microsoft) are building QC offerings. We position that software engineers should look into defining a set of software engineering practices that apply to QC's software. To start this process, we give examples of challenges associated with testing such software and sketch potential solutions to some of these challenges.

description: A computational method is developed for the study of mechanical response and fracture behavior of phase field crystals (PFC), to overcome a limitation of the PFC dynamics which lacks an effective mechanism for describing fast mechanical relaxation of the material system. The method is based on a simple interpolation scheme for PFC (IPFC) making use of a condition of the displacement field to satisfy local elastic equilibration, while preserving key characteristics of the original PFC model. We conduct a systematic study on the mechanical properties of a sample nanoribbon system with honeycomb lattice symmetry subjected to uniaxial tension, for numerical validation of the IPFC scheme and the comparison with the original PFC and modified PFC methods. Results of mechanical response, in both elasticity and fracture regimes, show the advantage and efficiency of the IPFC method across different system sizes and applied strain rates, due to its effective process of mechanical equilibration. A brittle fracture behavior is obtained in IPFC calculations, where effects of system temperature and chirality on the fracture strength and Young's modulus are also identified, with results agreeing with those found in previous atomistic simulations of graphene. The IPFC scheme developed here is generic and applicable to the mechanical studies using different types of PFC free energy functionals designed for various material systems.

description: Prior research and theory has suggested that rumination plays a role in nonsuicidal self-injury (NSSI), and rumination increases recall of negative autobiographical information in dysphoric individuals. Across two studies, we investigated whether rumination (versus distraction) differentially influences the recall of emotional words among dysphoric persons with and without a history of NSSI. Participants encoded unpleasant, neutral, and pleasant words and then were randomly assigned to either focus on the meaning and consequences of their emotions (i.e. rumination) or unrelated thoughts (i.e. distraction) before they were asked to recall encoded words. Across the two studies, we did not find a significant effect of rumination on memory for emotional words among dysphoric people with (Studies 1 and 2) or without a history of NSSI (Study 1). We did find that people were more likely to remember neutral words as opposed to unpleasant or pleasant words across studies, regardless of rumination condition. Together, results from these two well-powered studies provide fairly compelling evidence that rumination after encoding has little to no effect on recall for emotional words in people elevated on symptoms of depression or with NSSI history. These findings can be used to refine theories of rumination and NSSI.
