description: We report theoretical and experimental results on 4-wave capillary wave turbulence. A system consisting of two inmiscible and incompressible fluids of the same density can be written in a Hamiltonian way for the conjugated pair $(η,Ψ)$. When given the symmetry $z\to-z$, the set of weakly non-linear interacting waves display a Kolmogorov-Zakharov (KZ) spectrum $n_k\sim k^{-4}$ in wave vector space. The wave system was studied experimentally with two inmiscible fluids of almost equal densities (water and silicon oil) where the capillary surface waves are excited by a low frequency random forcing. The power spectral density (PSD) and probability density function (PDF) of the local wave amplitude are studied. Both theoretical and experimental results are in fairly good agreement with each other.

description: For an observation time {equal to} the universe age, the Heisenberg principle fixes the value of the smallest measurable mass at $m_{\rm H}=1.35 \times 10^{-69}$ kg and prevents to probe the masslessness for any particle using a balance. The corresponding reduced Compton length to $m_{\rm H}$ is $\lambdabar_{\rm H}$, and represents the length limit beyond which masslessness cannot be proved using a metre ruler. In turns, $\lambdabar_{\rm H}$ is equated to the luminosity distance $d_{\rm H}$ which corresponds to a red shift $z_{\rm H}$. When using the Concordance-Model parameters, we get $d_{\rm H} = 8.4$ Gpc and $z_{\rm H}=1.3$. Remarkably, $d_{\rm H}$ falls quite short to the radius of the {\it observable} universe. According to this result, tensions in cosmological parameters could be nothing else but due to comparing data inside and beyond $z_{\rm H}$. Finally, in terms of quantum quantities, the expansion constant $H_0$ reveals to be one order of magnitude above the smallest measurable energy, divided by the Planck constant

description: The marine red alga, Gracilaria eucheumatoides, is economically significant for its agar production and pharmacologically active compounds. This study reveals its complete mitochondrial genome (mitogenome), sequenced using Illumina’s next-generation technology. The mitogenome is a 25,909 bp circular molecule with a G + C content of 27.21%, comprising 24 protein-coding genes, two ribosomal RNA genes, 24 transfer RNA genes, and one open reading frame (ORF) with an unidentified function. Both gene structure and composition are highly conserved within Gracilaria. The phylogenetic analyses fully support a close relationship of G. eucheumatoides with other Gracilaria species, as well as its sister relationship with G. urvillei. This mitogenome sequencing effort of G. eucheumatoides provides crucial data for future phylogenetic research on marine red algae.

Narration and Comprehension of Paradox in Gauḍīya Literature
Creators: name: Graheli, Alessandro
Publisher: name: Rivista di Studi Sudasiatici
Year: 2007

description: Are the Absolute and the world different or non-different? The advantages and disadvantages of either view are synthesized in Gauḍīya theology in a doctrine derived from scriptural statements about the paradoxical nature of god. In this tradition this paradox is illustrated and explained in positive terms, through circles of narration and comprehension. Unlike other Vedāntic traditions, the assumption is not the impossibility of expression, but rather the convergence of contradictory aspects in the divine personality as the very mark of divinity.

The Existence of Sterile Neutrino Halos in Galactic Centers as an Explanation of the Black Hole mass - Velocity Dispersion Relation

description: If sterile neutrinos exist and form halos in galactic centers, they can give rise to observational consequences. In particular, the sterile neutrinos decay radiatively and heat up the gas in the protogalaxy to achieve hydrostatic equilibrium, and they provide the mass to form supermassive blackholes. A natural correlation between the blackhole mass and velocity dispersion thus arises $\log(M_{BH,f}/M_{\odot})=α\log (σ/200 {\rm km s^{-1}})+ β$ with $α\approx 4$ and $β\approx 8$.

description: The content of this thesis contains a study of the rings C(Rⁿ), L[sub c](Rⁿ), C[sup m](Rⁿ), C[sup ∞](Rⁿ), А(Rⁿ) and P(Rⁿ). We obtain the result that no two of the rings above can be isomorphic : in fact we prove the following : if Φ : A → B is a ring homomorphism where A, B are any two of the rings and A ⊂ B, then Φ(f) = f(p) for some p εRⁿ. We also characterise C(Rⁿ), C[sup m](Rⁿ), and C[sup ∞](Rⁿ) as rings.

description: We consider the optical properties of the half-filled AB-stacked bilayer graphene with the excitonic pairing and condensation between the layers. Both intra and interlayer local Coulomb interaction effects have been taken into account and the role of the exact Fermi energy has been discussed in details. We have calculated the absorption coefficient, refractive index, dielectric response functions and the electron energy loss spectrum for different interlayer Coulomb interaction regimes and for different temperatures. Considering the full four-band model for the interacting AB bilayer graphene, a good agreement is achieved with other theoretical and experimental works on the subject, in particular, limiting cases of the theory. The calculations, presented here, permit to estimate accurately the effects of excitonic pairing and condensation on the optical properties of the bilayer graphene. The modifications of the plasmon excitation spectrum are discussed in details for a very large interval of the interlayer interaction parameter.

description: We use a homogenization procedure for Maxwell's equations in order to obtain in the local limit the frequency ($ω$) dependent macroscopic dielectric response $ε^M(ω)$ of metamaterials made of natural constituents with any geometrical shape repeated periodically with any structure. We illustrate the formalism calculating $ε^M(ω)$ for several structures. For dielectric rectangular inclusions within a conducting material we obtained a very anisotropic response which changes along one direction from conductor-like at low $ω$ to a resonant dielectric-like at large $ω$, attaining a very small reflectance at intermediate frequencies unrelated to surface plasmon excitation and which can be tuned through geometrycal tayloring. A similar behavior is obtained for other shapes close to the percolation threshold.

description: We compare the abundances of various chemical species as derived with 3D hydrodynamical and classical 1D stellar atmosphere codes in a late-type giant characterized by T_eff=3640K, log g = 1.0, [M/H] = 0.0. For this particular set of atmospheric parameters the 3D-1D abundance differences are generally small for neutral atoms and molecules but they may reach up to 0.3-0.4 dex in case of ions. The 3D-1D differences generally become increasingly more negative at higher excitation potentials and are typically largest in the optical wavelength range. Their sign can be both positive and negative, and depends on the excitation potential and wavelength of a given spectral line. While our results obtained with this particular late-type giant model suggest that 1D stellar atmosphere models may be safe to use with neutral atoms and molecules, care should be taken if they are exploited with ions.

description: We report the new results of exchange bias effect in Nd_{1-x}Sr_{x}CoO_3 for x = 0.20 and 0.40, where the exchange bias phenomenon is involved with the ferrimagnetic (FI) state in a spontaneously phase separated system. The zero-field cooled magnetization exhibits the FI (T_{FI}) and ferromagnetic (T_C) transitions at ~ 23 and \sim 70 K, respectively for x = 0.20. The negative horizontal and positive vertical shifts of the magnetic hysteresis loops are observed when the system is cooled through T_{FI} in presence of a positive static magnetic field. Training effect is observed for x = 0.20, which could be interpreted by a spin configurational relaxation model. The unidirectional shifts of the hysteresis loops as a function of temperature exhibit the absence of exchange bias above T_{FI} for x = 0.20. The analysis of the cooling field dependence of exchange bias field and magnetization indicates that the ferromagnetic (FM) clusters consist of single magnetic domain with average size around \sim 20 and ~ 40 Å~ for x = 0.20 and 0.40, respectively. The sizes of the FM clusters are close to the percolation threshold for x = 0.20, which grow and coalesce to form the bigger size for x = 0.40 resulting in a weak exchange bias effect.

With increasing velocity of the ensemble we observe an evolution from a large chaotic sea with stickiness due to regular islands to thin chaotic channels with diffusive motion leading to Fermi acceleration. As a surprising consequence, we encounter a crossover, which is not parameter induced but rather occurs dynamically, from amplitude dependent tunable subdiffusion to universal normal diffusion in momentum space. In the high velocity case we observe particle focusing in phase space.

The $T$-matrix approach is well suited to implement potential scattering and thus provides a common framework for low-momentum transfer interactions in heavy-heavy and heavy-light quark systems. We assume that the underlying potentials can be estimated from the heavy-quark free energy computed in lattice QCD. We discuss constraints from vacuum spectroscopy, uncertainties arising from different choices of the potential, and the role of elastic and inelastic widths which are naturally accounted for in the $T$-matrix formalism.

description: The new distributed network vision for AI is to create a shared data interface by querying multiple data nodes simultaneously. This distributed approach is based on the agile, community-driven standard called Croissant ML, allowing users to query and understand responses from various data platforms that support the standard, such as Dataverse, Kaggle, HuggingFace, and OpenML. The results are processed in a standardized way, converting metadata into a knowledge graph integrated with ontologies, and ingesting structured content into Large Language Models (LLMs) that act as reasoning engines, interfacing between humans and AI. The prototype enables "chatting" with individual data nodes in the network while considering ethical and privacy constraints, using only information shared through open metadata records.

In our study, we investigate a disk-shaped two-dimensional electron system (2DES) with a metallic gate on the backside of the substrate. Importantly, we show that 2D plasmon polaritons hybridize with the TM$_0$ photonic mode of a dielectric waveguide formed by a sample substrate. We have developed a theory for plasmon-polaritons in an infinite 2DES. We find the experimental data to be in good agreement with the developed theory.

Representation theory of variety of algebras
Creators: name: Lee, Hei-Sook
Publisher: name: University of British Columbia
Year: 2010

description: While there is considerable literature about algebras satisfying a polynomial identity, there are only scant results about varieties of algebras. For such an algebra we can introduce the notions of bimodule, birepresentation and universal enveloping algebra as an extension of the notions of module and representation for associative algebras. Moreover, it is possible to define injective hulls for these restricted representations. We derive a rather concrete structure theorem of I-bimodules M for a finite dimensional algebra in a certain variety by studying a universal enveloping algebra and injective hulls.
Identification of Biased Terms in News Articles by Comparison of Outlet-specific Word Embeddings

description: Slanted news coverage, also called media bias, can heavily influence how news consumers interpret and react to the news. To automatically identify biased language, we present an exploratory approach that compares the context of related words. We train two word embedding models, one on texts of left-wing, the other on right-wing news outlets. Our hypothesis is that a word's representations in both word embedding spaces are more similar for non-biased words than biased words. The underlying idea is that the context of biased words in different news outlets varies more strongly than the one of non-biased words, since the perception of a word as being biased differs depending on its context. While we do not find statistical significance to accept the hypothesis, the results show the effectiveness of the approach. For example, after a linear mapping of both word embeddings spaces, 31% of the words with the largest distances potentially induce bias. To improve the results, we find that the dataset needs to be significantly larger, and we derive further methodology as future research direction. To our knowledge, this paper presents the first in-depth look at the context of bias words measured by word embeddings.

Classic neuropsychological approaches and powerful new techniques supported by rigorous methodological procedures enable neuroscientists to reveal the neuronal correlates of mental functions such as talking, reasoning, remembering, imaging, etc. This does not mean, however, that the brain expresses the mind in a rigid, deterministic way. Indeed, brain functioning is strongly modulated by bodily and environmental input, as well as by interaction with other individuals. In a nutshell, mind and brain are conceived as a reciprocally shaped unit which underpins human behaviour.

Publisher: name: Studi sulla Formazione
Year: 2012

description: The present paper collects some entries excluded from the original 1998 pamphlet titled "commiato dal Commiato" (a small farewell to the Great Farewell to "modernity" in philosophy), thus it tackles often with sarcastic flavour topics such as relativism, hermeneutics, fragmented knowledge, which mainly concern the debate between analytic and continental philosophy. The entries are related to each other in a sort of hypertextual structure rather than in a linear order.

La ricerca empirica in pedagogia
Creators: name: Baldacci, Massimo
Publisher: name: Studi sulla Formazione
Year: 2010

description: According to the author the pedagogical research has two convoys: the first epistemological (theoretical and historical), the other praxeology (experimental and empirical). Traveling together these two trains offer us the opportunity to see the face of critical pedagogy, or the reflexive dimension of doing research in education that translates better to the concept of action ricerca-azione. The most interesting aspect that emerges from this investigation is that the investigation is never separated from the ‘action and results that follow are never objective and definitive.

description: The electrocardiogram (ECG) is a well-known technique used to diagnose cardiac diseases. To acquire the spatial signal characteristics from the thorax, multiple electrodes are commonly used. Displacements of electrodes affect the signal morphologies and can lead to incorrect diagnoses. For quantitative analysis of these effects we propose the usage of a numerical computer simulation. In order to create a realistic representation of the human thorax including the heart and lung a three-dimensional model with a simplified geometry is used. The electrical excitation of the heart is modelled on a cellular level via the bidomain approach. To numerically solve the differential equations, describing the signal propagation within the body, we use the finite element method in COMSOL Multiphysics. The spatial gradients of the simulated body potentials are calculated to determine placement sensitivity maps. The simulated results show that the sensitivity is different for each considered point in time of each ECG wave. In general, the impact of displacement is increased as an electrode is more closely located to the signal source. However, in some specific regions associated with differential ECG leads the placement sensitivity distribution deviates from this simple circular pattern. The results provide useful information to enhance the understanding of placed specific effects on classical ECG features. By additional consideration of patient-specific characteristics in the future, the used model has the ability to investigate additional body-related aspects such as geometrical body shape or composition of various tissue types.
Inferring the morphology of AGN torus using X-ray spectra: A reliability study

description: Numerous X-ray spectral models have been developed to model emission reprocessed by the torus of an active galactic nucleus (AGN), e.g., UXCLUMPY, CTORUS, and MYTORUS. They span a range of assumed torus geometries and morphologies-some posit smooth gas distributions, and others posit distributions of clouds. It is suspected that given the quality of currently available data, certain model parameters, such as coronal power law photon index and parameters determining the morphology of the AGN torus, may be poorly constrained due to model degeneracies. In this work, we test the reliability of these models in terms of recovery of parameters and the ability to discern the morphology of the torus using XMM-Newton and NuSTAR spectral data. We perform extensive simulations of X-ray spectra of Compton-thick AGNs under six X-ray spectral models of the torus. We use Bayesian methods to investigate degeneracy between model parameters, distinguish models and determine the dependence of the parameter constraints on the instruments used. For typical exposure times and fluxes for nearby Compton-thick AGN, we find that several parameters across the models used here cannot be well constrained, e.g., the distribution of clouds, the number of clouds in the radial direction, even when the applied model is correct. We also find that Bayesian evidence values can robustly distinguish between a correct and a wrong model only if there is sufficient energy coverage and only if the intrinsic flux of the object is above a particular value determined by the instrument combination and the model considered.

description: We calculate the full transport counting statistics in a three-terminal tunnel device with one superconducting source and two normal-metal or ferromagnet drains. We obtain the transport probability distribution from direct Andreev reflection, crossed Andreev reflection, and electron transfer which reveals how these processes' statistics are determined by the device conductances. The cross-correlation noise is a result of competing contributions from crossed Andreev reflection and electron transfer, as well as antibunching due to the Pauli exclusion principle. For spin-active tunnel barriers that spin polarize the electron flow, crossed Andreev reflection and electron transfer statistics exhibit different dependencies on the magnetization configuration, and can be controlled by relative magnetization directions and voltage bias.
Quantum constraints, Dirac observables and evolution: group averaging versus Schroedinger picture in LQC

description: A general quantum constraint of the form $C= - \partial_T^2 \otimes B - I\otimes H$ (realized in particular in Loop Quantum Cosmology models) is studied. Group Averaging is applied to define the Hilbert space of solutions and the relational Dirac observables. Two cases are considered. In the first case, the spectrum of the operator $(1/2)π^2 B - H$ is assumed to be discrete. The quantum theory defined by the constraint takes the form of a Schroedinger-like quantum mechanics with a generalized Hamiltonian $\sqrt{B^{-1} H}$. In the second case, the spectrum is absolutely continuous and some peculiar asymptotic properties of the eigenfunctions are assumed. The resulting Hilbert space and the dynamics are characterized by a continuous family of the Schroedinger-like quantum theories. However, the relational observables mix different members of the family. Our assumptions are motivated by new Loop Quantum Cosmology models of quantum FRW spacetime. The two cases considered in the paper correspond to the negative and, respectively, positive cosmological constant. Our results should be also applicable in many other general relativistic contexts.

Radical classes of Boolean algebras
Creators: name: Galay, Theodore Alexander
Publisher: name: University of British Columbia
Year: 2010

description: This thesis obtains information about Boolean algebras by means of the radical concept. One group of results revolves about the concept, theorems, and constructions of general radical theory. We obtain some subdirect product representations by methods suggested by the theory. A large number of specific radicals are defined, and their properties and inter-relationships are examined. This provides a natural frame-work for results describing what epimorphs an algebra can have. Some new results of this nature are obtained in the process. Finally, a contribution is made to the structure theory of complete Boolean algebras. Product decomposition theorems are obtained, some of which make use of chains of radical classes.

description: This paper studies decentralized, Fountain and network-coding based strategies for facilitating data collection in circular wireless sensor networks, which rely on the stochastic diversity of data storage. The goal is to allow for a reduced delay collection by a data collector who accesses the network at a random position and random time. Data dissemination is performed by a set of relays which form a circular route to exchange source packets. The storage nodes within the transmission range of the route's relays linearly combine and store overheard relay transmissions using random decentralized strategies. An intelligent data collector first collects a minimum set of coded packets from a subset of storage nodes in its proximity, which might be sufficient for recovering the original packets and, by using a message-passing decoder, attempts recovering all original source packets from this set. Whenever the decoder stalls, the source packet which restarts decoding is polled/doped from its original source node. The random-walk-based analysis of the decoding/doping process furnishes the collection delay analysis with a prediction on the number of required doped packets. The number of doped packets can be surprisingly small when employed with an Ideal Soliton code degree distribution and, hence, the doping strategy may have the least collection delay when the density of source nodes is sufficiently large. Furthermore, we demonstrate that network coding makes dissemination more efficient at the expense of a larger collection delay. Not surprisingly, a circular network allows for a significantly more (analytically and otherwise) tractable strategies relative to a network whose model is a random geometric graph.
Definitions of kaḷavu in the Old Tamil Poetological Tradition.The Convergence of Interests
Creators: name: Wilden, Eva
Publisher: name: Rivista di Studi Sudasiatici
Year: 2006

description: The present paper is a study of the development of a concept that is a constitutive part of the division of Classical Tamil poetics concerned with the themes of Akam, love poetry. In the two poetological treatises belonging to the first millennium, the Tolkāppiyam Poruḷatikāram and the Iṟaiyaṉār Akapporuḷ, we find four different definitions of what kaḷavu is, a term denoting the phase of secret love for the poetic couple, in contradistinction to kaṟpu, the phase of publicly known or post-marital love. Considerations of structural plausibility as well as phrasal and stylistic analysis provide arguments for the systematic and temporal interrelation of sources.

description: Training a model-free deep reinforcement learning model to solve image-to-image translation is difficult since it involves high-dimensional continuous state and action spaces. In this paper, we draw inspiration from the recent success of the maximum entropy reinforcement learning framework designed for challenging continuous control problems to develop stochastic policies over high dimensional continuous spaces including image representation, generation, and control simultaneously. Central to this method is the Stochastic Actor-Executor-Critic (SAEC) which is an off-policy actor-critic model with an additional executor to generate realistic images. Specifically, the actor focuses on the high-level representation and control policy by a stochastic latent action, as well as explicitly directs the executor to generate low-level actions to manipulate the state. Experiments on several image-to-image translation tasks have demonstrated the effectiveness and robustness of the proposed SAEC when facing high-dimensional continuous space problems.
Mountains of Eternity: Raidhū and the Colossal Jinas of Gwalior
Creators: name: Granoff, Phyllis
Publisher: name: Rivista di Studi Sudasiatici
Year: 2006

description: This paper explores the unique political and religious circumstances surrounding the carving of the colossal Jina images at Gwalior fort in the 15th century. It focuses on the works of the Apabhraṁśa poet Raidhū, who was a pivotal figure in the Gwalior court and the Digambara community. In his poems Raidhū speaks often of the end of times, the Kali yuga. This paper argues that the carving of the colossal Jinas was part of a strategy to turn Gopālagiri into a holy mountain destined to survive the coming cataclysm. Medieval Jain texts give ample evidence of a belief among both Śvetāmbaras and Digambaras that certain holy mountains covered with wonderful images of the Jinas would be left unscathed at the destruction of the world. The paper also explores the intimate networks of patronage in 15th century Gwalior.
