description: We show a purely electronic cooling scheme to cool a charged mechanical resonator (MR) down to nearly the vibrational ground state by elaborately tuning bias gate voltages on the electrodes, which couple the MR by Coulomb interaction. The key step is the modification of time-dependent effective eigen-frequency of the MR based on the Lewis-Riesenfeld invariant. With respect to a relevant idea proposed previously [Li et al., Phys. Rev. A 83, 043803 (2011)], our scheme is simpler, more practical and completely within the reach of current technology.

description: The aim of the present paper is to investigate intrinsically the notion of a concircular $π$-vector field in Finsler geometry. This generalizes the concept of a concircular vector field in Riemannian geometry and the concept of a concurrent vector field in Finsler geometry. Some properties of concircular $π$-vector fields are obtained. Different types of recurrence are discussed. The effect of the existence of a concircular $π$-vector field on some important special Finsler spaces is investigated. The whole work is formulated in a coordinate-free form.

Όσον αφορά τις απόκρυφες Αποκαλύψεις, η έρευνα θα επικεντρωθεί στα ελληνικά κείμενα της Αποκάλυψης Πέτρου και Παύλου (το τμήμα του χειρογράφου του Akhmim και την ελληνική εκδοχή του C. Tischendorf). Οι χρωματικές εικόνες θα εντοπισθούν και θα αξιολογηθεί το περιεχόμενό τους όσον αφορά την σημασία του χρώματος στον αρχαίο κόσμο. Ιδιαίτερης σημασίας είναι η σύγκριση των χρωματικών εικόνων των αποκρύφων κειμένων με ανάλογες περιπτώσεων του κανονικού βιβλίου της Αποκάλυψης, η οποία θα αποδώσει πληροφορίες σχετικά με την συγγένεια ή την διαφοροποίηση των εξωκανονικών αποκαλύψεων με την αντίστοιχη κανονική. Σαν ερμηνευτικά εργαλεία σε αυτή την χρωματική έρευνα, θα χρησιμοποιήσω την ιστορικοκριτική μέθοδο, ονομαστικά την φιλολογική ανάλυση του κειμένου, όπως επίσης και τις αρχές της διακειμενικότητας και το πρίσμα της πολιτισμικής θεωρίας με έμφαση στην ιστορία των χρωμάτων.
description: My research aims to present a thorough overview of the usage of colours in the ancient Christian apocryphal texts. As for the apocryphal Apocalypses, the research will focus on the Greek texts of the Apocalypse of Peter and Paul (the fragment of the Akhmim manuscript and the Greek edition of C. Tischendorf). The colour images will be traced down and their content will be evaluated according to the meaning of colour in the ancient world. Of utmost interest is a comparison of the colour images of the apocryphal texts with analogous occurrences in the canonical book of Revelation, that provide information regarding the relation or the differentiation of the extracanonical apocalypses from the canonical one. As hermeneutical tools in this chromatic research, I will utilize the historical-critical exegetical tools, namely the philological analysis of the text, as well as the principles of intertextuality and the lenses of cultural theory with emphasis on the history of colours.

description: The asymptotic giant branch (AGB) of the globular cluster NGC 4372 appears to extend to unexpectedly high luminosities. We show, on the basis of proper motions and spatial distribution, that the extended AGB is indeed a likely part of the cluster. We also present the first spectra of the very cool (2600 K), very luminous (8000 Lsun), very dusty, oxygen-rich, purported long-period variable stars V1 and V2 that define the AGB tip. In particular, on the basis of their radial velocities, we conclude that V1 and V2 are probably members. We find that V1 and V2 are likely undergoing the superwind phase that terminates their nuclear-burning evolution. We hypothesise that the mass-loss processes that terminate the AGB are inhibited in NGC 4372 due to a lack of atmospheric pulsation and the high gas-to-dust ratio in the ejecta, leading to a delay in the associated enhanced mass loss and dust production. Previously predicted, but never observed, this explains the high mass of the white dwarf in Pease 1 in M15 without the need to invoke a stellar merger. If commonplace, this phenomenon has implications for the mass return from stars, the production of carbon stars and supernovae through the Universe's history, and the AGB contribution to light from unresolved metal-poor populations.

description: The extreme radiation dose received by vertex detectors at the Large Hadron Collider dictates stringent requirements on their cooling systems. To be robust against radiation damage, sensors should be maintained below -20 degree C and at the same time, the considerable heat load generated in the readout chips and the sensors must be removed. Evaporative CO2 cooling using microchannels etched in a silicon plane in thermal contact with the readout chips is an attractive option. In this paper, we present the first results of microchannel prototypes with circulating, two-phase CO2 and compare them to simulations. We also discuss a practical design of upgraded VELO detector for the LHCb experiment employing this approach.

description: Given a countably generated rigid C^*-tensor category C, we construct a planar algebra P whose category of projections Pro is equivalent to C. From P, we use methods of Guionnet-Jones-Shlyakhtenko-Walker to construct a rigid C^*-tensor category Bim whose objects are bifinite bimodules over an interpolated free group factor, and we show Bim is equivalent to Pro. We use these constructions to show C is equivalent to a category of bifinite bimodules over L(F_infty).

description: We study the long-time behavior of the scaled walker (particle) position associated with decoupled continuous-time random walk which is characterized by superheavy-tailed distribution of waiting times and asymmetric heavy-tailed distribution of jump lengths. Both the scaling function and the corresponding limiting probability density are determined for all admissible values of tail indexes describing the jump distribution. To analytically investigate the limiting density function, we derive a number of different representations of this function and, by this way, establish its main properties. We also develop an efficient numerical method for computing the limiting probability density and compare our analytical and numerical results.

description: We present local probe results on the honeycomb lattice antiferromagnet Ba3CuSb2O9. Muon spin relaxation measurements in zero field down to 20 mK show unequivocally that there is a total absence of spin freezing in the ground state. Sb NMR measurements allow us to track the intrinsic susceptibility of the lattice, which shows a maximum at around 55 K and drops to zero in the low-temperature limit. The spin-lattice relaxation rate shows two characteristic energy scales, including a field-dependent crossover to exponential low-temperature behavior, implying gapped magnetic excitations.

description: We investigate a six-dimensional universal extra-dimensional model in the extension of an effective neutrino mass operator. We derive the β-functions and renormalization group equations for the Yukawa couplings, the Higgs self-coupling, and the effecive neutrino mass operator in this model. Especially, we focus on the renormalization group running of physical parameters such as the Higgs self-coupling and the leptonic mixing angles. The recent measurements of the Higgs boson mass by the ATLAS and CMS collaborations at the LHC as well as the current three-flavor global fits of neutrino oscillation data have been taken into account. We set a bound on the six-dimensional model, using the vacuum stability criterion, that allows five Kaluza-Klein modes only, which leads to a strong limit on the cutoff scale. Furthermore, we find that the leptonic mixing angle θ_{12} shows the most sizable running, and that the running of the angles θ_{13} and θ_{23} are negligible. Finally, it turns out that the findings in this six-dimensional model are comparable with what is achieved in the corresponding five-dimensional model, but the cutoff scale is significantly smaller, which means that it could be detectable in a closer future.

description: We present a minimal continuum model of strongly adhering cells as active contractile isotropic media and use the model to study the effect of the geometry of the adhesion patch in controlling the spatial distribution of traction and cellular stresses. Activity is introduced as a contractile, hence negative, spatially homogeneous contribution to the pressure. The model shows that patterning of adhesion regions can be used to control traction stress distribution and yields several results consistent with experimental observations. Specifically, the cell spread area is found to increase with substrate stiffness and an analytic expression for the dependence is obtained for circular cells. The correlation between the magnitude of traction stresses and cell boundary curvature is also demonstrated and analyzed.

description: Background Considering the high number of new cases of cervical cancer each year caused by human papilloma viruses (HPVs), the development of an effective vaccine for the prevention and therapy of HPV-associated cancers, and in particular against the high-risk HPV-16 genotype, remains a priority. Vaccines expressing the E6 and E7 proteins, which are detectable in all HPV-positive pre-cancerous and cancer cells, might support the treatment of HPV-related lesions and clear already established tumors. Methods In this study, DNA and fowlpox virus recombinants expressing the E6F47R and E7GGG mutated forms of the HPV-16 E6 and E7 oncoproteins were generated, and their correct expression verified by RT-PCR, Western blotting and immunofluorescence. The immune responses were determined by ELISA and ELISPOT assays and the therapeutic efficacy was evaluated In mice, as a pre-clinical model of HPV-16 tumorigenicity, using heterologous (DNA/FP) or homologous (DNA/DNA and FP/FP) prime/ boost regimens after challenge with syngeneic TC-1* cells. Results The analyses of the different recombinants showed the correct expression of the inserted heterologous genes. After mice immunization, while specific anti-E6 and anti-E7 humoral responses were just detectable, specific T-cell responses were elicited. In the therapeutic protocols, after the challenge and the subsequent immunizations, a delay in cancer appearance was shown, thus confirming the pivotal role of the T-cell response in the control of tumor growth also in the absence of E6- and E7-specific antibodies. These in-vivo experiments resulted in higher numbers of tumor-free mice after either the homologous or heterologous immunizations compared to the controls. Conclusions These data establish a preliminary indication for the prevention and treatment of HPV-related tumors by the use of DNA and avipox constructs as safe and effective immunogens administered by the prime/boost strategy. The combined use of the recombinants expressing both the E6F47R and E7GGG proteins should improve the antitumor efficacy and represent an important approach to control/clear HPV-associated cancers.

description: In supersymmetric models of warm inflation, the large temperature of the radiation bath produced by the dissipative motion of the inflaton field may induce a significant thermal abundance of potentially dangerous gravitinos. While previous discussions of this problem focused on gravitino production only at the end of warm inflation, similarly to conventional reheating scenarios, we study the full evolution of the gravitino abundance during and after inflation for simple monomial potentials, taking into account the enhanced gravitino and possibly gaugino masses due to supersymmetry breaking during inflation and the smooth transition into a radiation-dominated era. We find, on one hand, that the continuous thermal production increases the gravitino yield, although, on the other hand, `freeze-out' occurs at temperatures much lower than previously estimated. Moreover, for sufficiently strong dissipation, which allows for sub-planckian inflaton values, the lower radiation temperature significantly alleviates and possibly solves the gravitino problem, with a baryon asymmetry being nevertheless produced through dissipative effects. Our analysis may also be relevant to standard reheating as an oscillating inflaton will also change the gravitino mass, potentially modifying the produced gravitino yield.

description: We analyze the potential of Compact Linear Colliders based on the γ-e collisions to search for the radion in the Randall-Sundrum model, where compactification radius of the extra dimension is stabilized by the radion, which is a scalar field lighter than the graviton Kaluza-Klein states. The radion production in the high energy γ-e colliders with the polarization of the electron beams are calculated in detail. Numerical evaluation shows that if the radion mass is not too heavy with the mass order of GeV then the reaction can give observable cross section in future colliders at the high degree of polarization.

Mass loss in pre-main sequence stars via coronal mass ejections and implications for angular momentum loss

description: We develop an empirical model to estimate mass-loss rates via coronal mass ejections (CMEs) for solar-type pre-main-sequence (PMS) stars. Our method estimates the CME mass-loss rate from the observed energies of PMS X-ray flares, using our empirically determined relationship between solar X-ray flare energy and CME mass: log(M_CME [g]) = 0.63 x log(E_flare [erg]) - 2.57. Using masses determined for the largest flaring magnetic structures observed on PMS stars, we suggest that this solar-calibrated relationship may hold over 10 orders of magnitude in flare energy and 7 orders of magnitude in CME mass. The total CME mass-loss rate we calculate for typical solar-type PMS stars is in the range 1e-12 to 1e-9 M_sun/yr. We then use these CME mass-loss rate estimates to infer the attendant angular momentum loss leading up to the main sequence. Assuming the CME outflow rate for a typical ~1 M_sun T Tauri star is < 1e-10 M_sun/yr, the resulting spin-down torque is too small during the first ~1 Myr to counteract the stellar spin-up due to contraction and accretion. However, if the CME mass-loss rate is >1e-10 M_sun/yr, as permitted by our calculations, the CME spin-down torque may influence the stellar spin evolution after an age of a few Myr.

description: Membrane technology is widely used in food processing, fouling remains a significant issue that affects efficiency. Fouling leads to the buildup of undesirable substances in the membrane that resulting in a decrease in permeate flux. Membrane fouling can be categorized into three types: internal fouling, external fouling, and fouling due to concentration polarization. There are several mitigation strategies used to deal with fouling in dairy industry. That will ensure improved membrane effectiveness and quality production.

description: Subdiffusive fractional equations are not structurally stable with respect to spatial perturbations to the anomalous exponent (Phys. Rev. E 85, 031132 (2012)). The question arises of applicability of these fractional equations to model real world phenomena. To rectify this problem we propose the inclusion of the random death process into the random walk scheme from which we arrive at the modified fractional master equation. We analyze the asymptotic behavior of this equation, both analytically and by Monte Carlo simulation, and show that this equation is structurally stable against spatial variations of anomalous exponent. Additionally, in the continuous and long time limit we arrived at an unusual advection-diffusion equation, where advection and diffusion coefficients depend on both the death rate and anomalous exponent. We apply the regularized fractional master equation to the problem of morphogen gradient formation.

AN ANALYSIS OF PHYSICAL HEALTH AND POSITIVE PSYCHOLOGY
Creators: name: Divya
Publisher: name: Zenodo
Year: 2023

description: The scientific study of happiness and thriving is known as "positive psychology." The field of positive psychology aims to supplement and expand upon the more commonplace problem-focused school of thought. The field of positive psychology focuses on studying flourishing mental states, including but not limited to joy, as well as flourishing personality characteristics, interpersonal connections, and social structures. In this article, we detail the research that links positive psychology concepts to improved physical well-being. Psychological health assets (such as pleasant emotions, life satisfaction, optimism, a sense of meaning and purpose in one's life, and social support) have been shown to correlate with health in various contexts. Whether or not therapies based on positive psychology enhance physical health is an open question. It is explored how positive psychology may be used to improve health in the future. We conclude that there is promise in applying positive psychology to health, but more must be done.

description: A new nonconventional mechanism for the basic 2π-fusion reaction pn --> d+(ππ)_0 in the energy region T_p = 1.0-1.4 GeV is suggested. The mechanism is aimed at providing a consistent explanation for the comprehensive experimental studies of this reaction in exclusive setting done recently by the WASA-at-COSY Collaboration. The basic assumption of the model proposed is the production of the I(JP) = 0(3+) dibaryon resonance D03 in the pn collision. The interference of two decay channels of this resonance: D_03 --> d + σ --> d + (ππ)_0 and D_03 --> D_12 + π --> d + (ππ)_0 is shown to give a strong near-threshold enhancement in the ππ invariant mass spectrum, which is well known as the ABC effect. The σ-meson parameters found to reproduce the ABC enhancement are in a general agreement with models which predict the chiral symmetry restoration at high excitation energy and/or high density of matter, although they are essentially less than those accepted for the free σ meson. So, this result might be considered as an indication of partial chiral symmetry restoration in dense and excited quark matter.

DESIGN OF VASCULARIZABLE SCAFFOLDS FOR LARGE TISSUE ENGINEERING

Year: 2014

description: The emerging field of tissue engineering is dedicated to restore, maintain or improve the functions of damaged or lost human tissues. However, despite significant successes have been achieved over the last 20 years, several challenges still remain, preventing a pervasive clinical application of tissue engineering. One of the main challenges lies in the development of scaffolding materials able to mimic the complex organization of the in vivo milieu and provide tailored stimuli for tissue growth and maturation. A fundamental aspect of this problem resides in the design of scaffolds having three-dimensional vascular architecture, able to provide optimal nutrients diffusion, supporting and maintaining viable tissue in vitro, and capable to promote vascularization after implantation. The lack of proper vascularization is currently limiting the size of the engineered tissues to smaller than clinically relevant dimensions. The aim of this PhD work, merging the study of novel biomaterials and the development of original microfabrication methods, is to create enabling technologies towards the design of innovative scaffolds for large tissues engineering. For this purpose, a library of RGD-mimetic hydrogels with controlled chemical, mechanical and biological features has been developed. The obtained hydrogels have been combined with foaming and sacrificial molding techniques to engineer customizable scaffolds with hierarchical three-dimensional architectures. These novel hydrogel scaffolds supported optimal three-dimensional cell growth and promoted in vitro vascularization in large constructs. The reported results suggest that the presented approach could represent a viable solution to scale engineered tissue to clinically relevant dimensions releasing the full potential of regenerative medicine.

description: We present results for the one loop anomalous dimension matrix of flavor non-singlet twist-4 operators of lowest spin that contribute to the leading moment of the $F_2$ structure function in deep inelastic electron-nucleon scattering. We analyze the flavor structure of the anomalous dimension matrix and decompose the leading moment of $F_2$ into separate flavor channels. In addition to building on previous work with higher-twist operators, these results can provide a benchmark for future work that generalizes to include the higher moments as well. We include non-perturbative input from the lattice and phenomenological estimates of the twist-4 matrix elements and estimate the twist-4 contributions to the leading moment of $F_2$. The results suggest that the overall twist-4 contribution may be suppressed due to either cancellations among the twist-4 terms or inherently small twist-4 matrix elements.

It discusses the different approaches adopted by the European Court to deal with the responsibility of Member States of international organizations. It contends that the Court based its reasoning on two different concepts of international organization, founded on their original or derived nature. After introducing the theme, section II deals with the attribution of conduct to Member States and international organizations. Section III analyses the merits of the two judgments, distinguishing between the Chamber (III.1) and the Grand Chamber (III.2). In conclusion, section IV proposes a reading of the two judgments considering that the legal systems developed by international organizations are neither purely original or purely derived from international law.

description: We present here an optomechanical system fabricated with novel stress management techniques that allow us to suspend an ultrathin defect-free silicon photonic-crystal membrane above a Silicon-on-Insulator (SOI) substrate with a gap that is tunable to below 200 nm. Our devices are able to generate strong attractive and repulsive optical forces over a large surface area with simple in- and outcoupling and feature the strongest repulsive optomechanical coupling in any geometry to date (gOM/2π ~ -65 GHz/nm). The interplay between the optomechanical and photo-thermal-mechanical dynamics is explored, and the latter is used to achieve cooling and amplification of the mechanical mode, demonstrating that our platform is well-suited for applications in low-power mass, force, and refractive index sensing as well as and optomechanical accelerometry.

description: We report the observation of an anomalous antibunching dip in intensity autocorrelation function with photon correlation measurements on a single-photon emitter (SPE). We show that the anomalous dip observed is a manifestation of quantum nature of SPEs. Taking population dynamics in a quantum two-level system into account correctly, we redefine intensity autocorrelation function. This is of primary importance for precisely evaluating the lowest-level probability of multiphoton generation in SPEs toward realizing versatile pure SPEs for quantum information and communication.

description: We present an efficient and accurate algorithm for principal component analysis (PCA) of a large set of two dimensional images, and, for each image, the set of its uniform rotations in the plane and its reflection. The algorithm starts by expanding each image, originally given on a Cartesian grid, in the Fourier-Bessel basis for the disk. Because the images are bandlimited in the Fourier domain, we use a sampling criterion to truncate the Fourier-Bessel expansion such that the maximum amount of information is preserved without the effect of aliasing. The constructed covariance matrix is invariant to rotation and reflection and has a special block diagonal structure. PCA is efficiently done for each block separately. This Fourier-Bessel based PCA detects more meaningful eigenimages and has improved denoising capability compared to traditional PCA for a finite number of noisy images.

INTEGRATION OF DIFFERENT PATHWAYS IN EARLY STAGE OF ALZHEIMER'S DISEASE PATHOGENESIS, FROM ACTIN REMODELLING TO AΒ FORMATION

description: Alzheimer disease (AD) pathogenesis is the result of an interplay of crossing pathways, as amyloid cascade and synaptic failure. It has been shown that A? is liberated from the amyloid precursor protein (APP) by BACE and ?-secretase activity. Alternatively, APP is cleaved within A? domain by ADAM10, which prevents A? formation. ADAM10 is a synaptic protein and works as sheddase towards several neuronal cell adhesion molecules. Therefore, ADAM10 activity can regulate not only A? generation, but also the synaptic morphology and the degree of functional synaptic connectivity. ADAM10 represents a potential pharmacological target for AD because the upregulation of its activity limits A? formation and affects synaptic function. Since ADAM10 synaptic localization/activity is controlled by the interactions with different protein partners, we aimed at identifying novel protein partners of ADAM10. To this, we performed a yeast two-hybrid screening, using ADAM10 C-terminal tail as a bait. We took advantage of several biochemical and imaging technique to analyze the role of such interaction. The results revealed the cyclase-associated protein 2 (CAP2) as a new ADAM10 binding partner. CAP2 is a regulator of actin dynamics and, thereby, of spines morphology, and could be involved in the modulation of ADAM10 synaptic localization/activity. Here we confirmed ADAM10/CAP2 interaction and we identified the domains responsible for the association. Moreover, we defined the region of CAP2 involved in actin binding and we analyzed the effect of such domain on ADAM10 synaptic localization. CAP2 can represent the crossing point between different aspects of AD pathogenesis, such as the amyloid cascade and actin-dependent spines shaping, thus taking part in a new cellular mechanism underlying synaptic dysfunction in AD.

description: We present the first accurate characterization of high-degree modes, derived using the best MDI full-disk full-resolution data set available. A ninety day long time series of full-disk two arc-second per pixel resolution dopplergrams was acquired in 2001. These dopplergrams were spatially decomposed using our best estimate of the image scale and the known components of MDI's image distortion. A multi-taper power spectrum estimator was used to generate power spectra up to l = 1000, with a large number of tapers to reduce the realization noise, while the blending at high degrees negates the need for high spectral resolution. These power spectra were fitted for all degrees and all azimuthal orders, between l = 100 and l = 1000. This fitting generated in excess of 6x10^6 individual estimates of ridge frequencies, line-widths, amplitudes and asymmetries (singlets: l,n,m), corresponding to some 6,000 multiplets (l,n). Fitting at high degrees generates ridge characteristics, characteristics that do not correspond to the underlying mode characteristics. We used a sophisticated forward modeling to recover the best possible estimate of the underlying mode characteristics (mode frequencies, as well as line-widths, amplitudes and asymmetries). We describe in detail this modeling and its validation. The modeling has been extensively reviewed and refined, by including an iterative process to improve its input parameters to better match the observations. Also, the contribution of the leakage matrix on the accuracy of the procedure has been carefully assessed. We present the derived set of corrected mode characteristics, discuss their uncertainties and the precision of the ridge to mode correction schemes. In our conclusions, we address how to further improve these estimates, and the implications for other data sets, like GONG+ and HMI.

description: The isoscalar giant monopole resonance (ISGMR) in even-A Cd isotopes has been studied by inelastic $α$-scattering at 100 MeV/u and at extremely forward angles, including 0deg. The asymmetry term in the nuclear incompressibility extracted from the ISGMR in Cd isotopes is found to be $K_τ = -555 \pm 75$ MeV, confirming the value previously obtained from the Sn isotopes. ISGMR strength has been computed in relativistic RPA using NL3 and FSUGold effective interactions. Both models significantly overestimate the centroids of the ISGMR strength in the Cd isotopes. Combined with other recent theoretical effort, the question of the "softness" of the open-shell nuclei in the tin region remains open still.

description: Recently, we have proposed a novel approach (arxiv:1205.3996) to deal with the sign problem that hinders Monte Carlo simulations of many quantum field theories (QFTs). The approach consists in formulating the QFT on a Lefschetz thimble. In this paper we concentrate on the application to a scalar field theory with a sign problem. In particular, we review the formulation and the justification of the approach, and we also describe the Aurora Monte Carlo algorithm that we are currently testing.

The Anisotropic Transport Effects On The Dilute Plasmas

description: We examine the linear stability analysis of a hot, dilute and differentially rotating plasma by considering anisotropic transport effects. In the dilute plasmas, the ion Larmor radius is small compared with its collisional mean free path. In this case, the transport of heat and momentum along the magnetic field lines become important. This paper presents a novel linear instability that may more powerful and greater than ideal magnetothermal instability (MTI) and ideal magnetorotational instability (MRI) in the dilute astrophysical plasmas. This type of plasma is believed to be found in the intracluster medium of galaxy clusters and radiatively ineffective accretion flows around black holes. We derive the dispersion relation of this instability and obtain the instability condition. There is at least one unstable mode that is independent of the temperature gradient direction for a helical magnetic field geometry. This novel instability is driven by the gyroviscosity coupled with differential rotation. Therefore we call it as gyroviscous modified magnetorotational instability (GvMRI). We examine how the instability depends on signs of the temperature gradient and the gyroviscosity, and also on the magnitude of the thermal frequency and on the values of the pitch angle. We provide a detailed physical interpretation of obtained results. The GvMRI is applicable not only to the accretion flows and intracluster medium but also to the transition region between cool dense gas and the hot low-density plasma in stellar coronae, accretion disks, and the multiphase interstellar medium because of being independent of the temperature gradient direction.

Time averaged Einstein relation and fluctuating diffusivities for the Lévy walk

Year: 2012

description: The Lévy walk model is a stochastic framework of enhanced diffusion with many applications in physics and biology. Here we investigate the time averaged mean squared displacement $\bar{δ^2}$ often used to analyze single particle tracking experiments. The ballistic phase of the motion is non-ergodic and we obtain analytical expressions for the fluctuations of $\bar{δ^2}$. For enhanced sub-ballistic diffusion we observe numerically apparent ergodicity breaking on long time scales. As observed by Akimoto \textit{Phys. Rev. Lett.} \textbf{108}, 164101 (2012) deviations of temporal averages $\bar{δ^2}$ from the ensemble average $< x^2 >$ depend on the initial preparation of the system, and here we quantify this discrepancy from normal diffusive behavior. Time averaged response to a bias is considered and the resultant generalized Einstein relations are discussed.
