Subjects: subject: Astrophysics (astro-ph)

description: Microlensing maps -- that is, contours of equal numbers of events per $10^6$ source stars -- are provided for the inner Galaxy under two alternative hypotheses : (1) the bulge is an oblate axisymmetric spheroid or (2) the bulge is a prolate bar. Oblate spheroids yield a total of $\sim 12$ events per year per $10^6$ stars at Baade's Window ($\sim 15$ events if the disk is maximal). The event rate is slightly lower for prolate bars viewed at $\sim 45^\circ$ and the maps have a characteristic asymmetry between positive and negative longitudes. Prolate bars can yield mild amplifications of the event rate if viewed almost down the long axis. The disk provides the dominant lensing population on the bulge major axis for $|\ell | \gta 6^\circ$. Measurements of the rate at major axis windows can test for disk dark matter or maximal disk models.

description: Η τρισδιάστατη εκτύπωση αποτελεί μία αναπτυσσόμενη τεχνολογία που υπόσχεται πλήθος εφαρμογών με γρηγορότερο, οικονομικότερο και ευκολότερο τρόπο, αντικαθιστώντας σταδιακά τις παραδοσιακές τεχνικές κατασκευής. Υπάρχει πληθώρα τεχνολογιών που μπορούν να εφαρμοστούν καθώς επίσης και πολλοί τύποι υλικών που μπορούν να χρησιμοποιηθούν. Στην παρούσα διπλωματική εργασία αναλύθηκαν οι προσθετικές μέθοδοι που έχουν μελετηθεί μέχρι σήμερα στα κεραμικά υλικά. Οι προσθετικές μέθοδοι αυτοί είναι η εναπόθεση συγκολλητικής ουσίας (Binder Jetting), οι διεργασίες εξώθησης υλικού (Material Extrusion), οι διεργασίες εναπόθεσης υλικού (Material Jetting), οι διεργασίες φωτοπολυμερισμού σε κάδο (Vat Polymerization), οι διεργασίες εναπόθεσης με κατευθυνόμενη ενεργειακή δέσμη (Direct Energy Deposition), οι διεργασίες επάλληλων φύλλων (Sheet Lamination) και οι διεργασίες σύντηξης πούδρας σε κλίνη (Powder Bed Fusion). Συγκεκριμένα το ενδιαφέρον την παρούσας εργασίας στράφηκε στην επιλεκτική τήξη και στην επιλεκτική πυροσυσσωμάτωση με λέιζερ (Selective Laser Melting/Selective Laser Sintering) αλλά και στη σύγκρισή τους με τις υπόλοιπες προσθετικές μεθόδους κατασκευής. Η επιλεκτική τήξη και η επιλεκτική πυροσυσσωμάτωση με λέιζερ για τα κεραμικά, συγκριτικά με κάποιες άλλες μεθόδους κατασκευής όπως οι διεργασίες φωτοπολυμερισμού σε κάδο, δεν είναι αρκετά μελετημένες. Η επιλεκτική τήξη με λέιζερ δεν χρειάζεται μετέπειτα επεξεργασία, αποδίδει απευθείας ένα πυκνό αντικείμενο το οποίο όμως δεν είναι απαλλαγμένο από εσωτερικές ρωγμές και πορώδες. Η επιλεκτική τήξη και η επιλεκτική πυροσυσσωμάτωση με λέιζερ καταφέρνουν να κατασκευάσουν πολύπλοκες γεωμετρίες με επιφανειακή τραχύτητα σε μικρό βαθμό. Η διαδικασία της προθέρμανσης έχει δειχθεί ότι βελτιώνει την πυκνότητα των αντικειμένων αλλά και των εσωτερικών ρωγμών. Η επιλεκτική τήξη και η επιλεκτική πυροσυσσωμάτωση με λέιζερ στα κεραμικά είναι πολλά υποσχόμενες τεχνολογίες αλλά για να καταφέρουν να καθιερωθούν στον οδοντιατρικό χώρο χρειάζονται βελτίωση στην ακρίβεια κατασκευής, στην τελική επιφάνεια του αντικειμένου και βελτίωση της πυκνότητας και των μηχανικών ιδιοτήτων. Παραμένει πρόκληση η παραγωγή εξαιρετικά αξιόπιστων κεραμικών οδοντιατρικών αποκαταστάσεων με προσθετικές μεθόδους κατασκευής που μπορούν να αντέξουν δεκαετίες μασητικής φόρτισης.

description: L’impegno degli organismi europei intesi come il Consiglio d’Europa e l’Unione Europea in merito all’insegnamento delle lingue e alla diffusione del multilinguismo da molti anni è assiduo e costante. L’Europa considera la formazione linguistica dei suoi cittadini uno dei punti cardine del futuro del vecchio continente, non solo per scelta culturale o di indirizzo educativo, ma all’interno di un preciso disegno politico a largo raggio. Non intendiamo qui ripercorrere il lungo cammino che dal Progetto Lingue Vive degli anni ’70, passando per il Quadro Comune Europeo di riferimento per le lingue, arriva agli ultimi documenti sul multilinguismo, sull’insegnamento delle lingue e ai Piani di Azione che se ne occupano a livello pratico e operativo. Quello che ci interessa è estrapolare dai principali dei molti documenti in merito una serie di indicazioni ricorrenti, di riflessioni e principi più volte ribaditi a proposito dell’insegnamento delle lingue straniere a bambini, confrontarli con la situazione odierna dell’insegnamento delle lingue straniere a bambini tra i sei e gli undici anni per delineare alcune delle sfide che la scuola primaria italiana deve affrontare per diventare davvero una scuola che forma futuri cittadini europei plurilingui fin dall’età dell’infanzia.

description: We describe few aspects of the quantum symmetries of some massless two-dimensional field theories. We discuss their relations with recent proposals for the factorized scattering theories of the massless $PCM_1$ and $O(3)_{θ=π}$ sigma models. We use these symmetries to propose massless factorized S-matrices for the $su(2)$ sigma models with topological terms at any level, alias the $PCM_k$ models, and for the $su(2)$-coset massless flows.

description: The functionality of materials is determined by their composition and microstructure, that is, the distribution and orientation of crystalline grains, grain boundaries and the defects within them. The characterisation of the material's microstructure is therefore critical for materials applications such as catalysis, energy storage and buildings. Until now, characterization techniques that map the distribution of grains, their orientation, and the presence of defects have either been limited to surface investigations, to spatial resolutions of a few hundred nanometres, or to systems of thickness around one hundred nanometres, thus requiring destructive sample preparation for measurements and preventing the study of system-representative volumes or the investigation of materials under operational conditions. Here, we present X-ray linear dichroic orientation tomography, a quantitative, non-invasive technique that allows for an intra- and inter-granular characterisation of extended polycrystalline and amorphous materials in three dimensions (3D). We present the detailed characterisation of a polycrystalline sample of vanadium pentoxide (V2O5), a key catalyst in the production of sulfuric acid. In addition to determining the nanoscale composition, we map the crystal orientation throughout the polycrystalline sample with 73 nm spatial resolution. We identify grains, as well as twist, tilt, and twin grain boundaries. We further observe the creation and annihilation of topological defects promoted by the presence of volume crystallographic defects in 3D. Our method's non-destructive and spectroscopic nature opens the door to in-operando combined chemical and microstructural investigations of functional materials, including energy and mechanical materials in existing industries, as well as quantum materials for future technologies.
Spin-orbit coupling effects in zinc-blende InSb and wurtzite InAs nanowires: Realistic calculations with multiband $\vec{k} \cdot \vec{p}$ method

description: A systematic numerical investigation of spin-orbit fields in the conduction bands of III-V semiconductor nanowires is performed. Zinc-blende InSb nanowires are considered along [001], [011], and [111] directions, while wurtzite InAs nanowires are studied along [0001] and [10$\overline{1}$0] or [11$\overline{2}$0] directions. Realistic multiband $\vec{k} \cdot \vec{p}\,$ Hamiltonians are solved by using plane-wave expansions of real-space parameters. In all cases the linear and cubic spin-orbit coupling parameters are extracted for nanowire widths from 30 to 100 nm. Typical spin-orbit energies are on the $μ$eV scale, except for InAs wurtzite nanowires grown along [10$\overline{1}$0] or [11$\overline{2}$0], in which the spin-orbit energy is about meV, largely independent of the wire diameter. Significant spin-orbit coupling is obtained by applying a transverse electric field, causing the Rashba effect. For an electric field of about 4 mV/nm the obtained spin-orbit energies are about 1 meV for both materials in all investigated growth directions. The most favorable system, in which the spin-orbit effects are maximal, are InAs WZ nanowires grown along [1010] or [11$\overline{2}$0], since here spin-orbit energies are giant (meV) already in the absence of electric field. The least favorable are InAs WZ nanowires grown along [0001], since here even the electric field does not increase the spin-orbit energies beyond 0.1 meV. The presented results should be useful for investigations of optical orientation, spin transport, weak localization, and superconducting proximity effects in semiconductor nanowires.

description: In this paper, we extend G{é}rard's formula for the solution of the Benjamin--Ono equation on the line to square integrable and real valued initial data. Combined with this formula, we also extend the G{é}rard's formula for the zero dispersion limit of the Benjamin--Ono equation on the line to more singular initial data. In the derivation of the extension of the formula for the zero dispersion limit, we also find an interesting integral equality, which might be useful in other contexts.

description: This thesis provides a thorough understanding of the interests-values interplay utilised by India and Australia’s to enable their meta-narrative identity utilisation for revitalisation of strategic relations. It simultaneously illustrates the gaps in collaborative endeavours that need to be filled for ensuring the long-term sustainability of India-Australia strategic relations. By employing the strategic partnership framework developed by Wilkins (2008), it compares the India-Australia strategic partnership’s trajectory, with India-Russia and Australia-Japan strategic partnerships (their strongest strategic partnerships) along three phases, i.e., inception, implementation, evaluation. Theories of classical realism and constructivism have been integrated within inception and evaluation phases for scrutinising each partnership’s interests-values interplay. Findings reveal that India and Australia need to move beyond the pursuit of trade-related economic goals, and instead work towards bolstering security, people-to-people linkages. This would allow them to build mutual understanding, trust, and in turn sustain their strategic partnership by helping them in navigating through each other’s priorities, sensitivities.
IL RUOLO DELLA CORTESIA NELLA FORMAZIONE DELLA COMPETENZA INTERCULTURALE

Subjects: cortesia; competenza interculturale; competenza comunicativa

description: Il tema della cortesia è tuttora oggetto di un notevole dibattito tra quanti sostengono la visione universalistica proposta dal modello di Brown e Levinson, basata sul principio di cooperazione e sul concetto di “faccia”, e coloro che propugnano una concezione relativistica, ponendo l’accento sulle percezioni della cortesia dei parlanti. In contrasto con questi due punti di vista si è andato affermando un filone di studi che, pur ammettendo alcuni principi generali di base, ritiene che la cortesia sia concettualizzata in modo differente nelle varie culture, per cui i giudizi dei parlanti sulla cortesia degli enunciati sarebbero condizionati dalle norme di comportamento specifiche della loro cultura. Assumendo come riferimento teorico questa terza prospettiva, si prendono in considerazione alcune differenze interculturali significative, dovute all’intreccio di varie dimensioni della cultura, allo scopo di proporre un approccio didattico al fenomeno della cortesia imperniato sulla riflessione metaculturale e finalizzato al superamento dello stereotipo secondo cui esisterebbero popoli più cortesi di altri.

description: This note aims to provide an entrée to two developments in two-dimensional topological gravity -- that is, intersection theory on the moduli space of Riemann surfaces -- that have not yet become well-known among physicists. A little over a decade ago, Mirzakhani discovered \cite{M1,M2} an elegant new proof of the formulas that result from the relationship between topological gravity and matrix models of two-dimensional gravity. Here we will give a very partial introduction to that work, which hopefully will also serve as a modest tribute to the memory of a brilliant mathematical pioneer. More recently, Pandharipande, Solomon, and Tessler \cite{PST} (with further developments in \cite{Tes,BT,STa}) generalized intersection theory on moduli space to the case of Riemann surfaces with boundary, leading to generalizations of the familiar KdV and Virasoro formulas. Though the existence of such a generalization appears natural from the matrix model viewpoint -- it corresponds to adding vector degrees of freedom to the matrix model -- constructing this generalization is not straightforward. We will give some idea of the unexpected way that the difficulties were resolved.

description: Finite dimensional entanglement for pure states has been used extensively in quantum information theory. Depending on the tensor product structure, even set of separable states can show non-intuitive characters. Two situations are well studied in the literature, namely the unextendible product basis by Bennett et al. [Phys. Rev. Lett. 82, 5385, (1999)], and completely entangled subspaces explicitly given by Parthasarathy in [Proc. Indian Acad. Sci. Math. Sci. 114, 4 (2004)]. More recently, Boyer, Liss, and Mor [Phys. Rev. A 95, 032308 (2017)]; Boyer and Mor [Preprints 2023080529, (2023)]; and Liss, Mor, and Winter [Lett. Math. Phys, 114, 86 (2024)] have studied spaces which have only finitely many pure product states. We carry this further and consider the problem of perturbing different spaces, such as the orthogonal complement of an unextendible product basis and also Parthasarathy's completely entangled spaces, by taking linear spans with specified product vectors. To this end, we develop methods and theory of variations and perturbations of the linear spans of certain unextendible product bases, their orthogonal complements, and also Parthasarathy's completely entangled sub-spaces. Finally, we give examples of perturbations with infinitely many pure product states.

description: Recently discovered mirror neurons systems play a major explanatory role in the understanding of human features like imitation, empathy and also language learning. This neural system is at the basis of social, interpersonal and affiliative behaviour. Mirror brain cells circuits are active during imitation activities and may contribute to the ability of learning a language. This article addresses some theoretical implications of the discovery of mirror neurons and will try to evaluate to what extent it can provide a new empirical ground for research in foreign language acquisition.

description: As photosynthetic organisms, Cyanobacteria play a crucial role in ecosystems. They are highly adaptable and can be found in various habitats. During summer, cyanobacterial blooms, often with toxin-producing species, pose a threat to humans and animals. As primary producers, cyanobacteria are attractive prey for predators. Research on predatory bacteria has gained increasing importance in recent years. However, only a few predatory bacteria that prey on cyanobacteria are known, and their properties are poorly characterized. The defense mechanisms of cyanobacteria against predatory bacteria are also unknown. This work describes the interaction of the filamentous cyanobacterium Anabaena variabilis with predatory bacteria. Initially, freshwater isolates were screened for predatory bacteria. Six isolates were selected and examined in more detail using metagenome analysis and microscopy. Lysobacter brunescens and Candidatus Venantispira tubingensis, a newly discovered bacterium, have been identified as predatory bacteria of A. variabilis. Candidatus Venantispira tubingensis belongs to the phylum Bacteroidota and is a representative of a new genus in the family Saprospiraceae. It forms spiral, multicellular filaments up to 50 µm long and it and close relatives have been found in Germany, Italy, New Mexico, and Costa Rica. Venantispira preys on filamentous and unicellular cyanobacteria. The cell surface of Venantispira carries outer membrane vesicle chains and smaller, possibly adhesive filaments, which could play a role in the lysis mechanism. Venantispira moves along the prey filament by alternating forward and backward movements until the prey cells finally lyse. This mechanism has not yet been described for predatory bacteria. Venantispira only lyses vegetative cells, while akinetes are not lysed. Therefore, akinetes play a role in the defense A. variabilis against bacterial predators. Further research is needed to fully understand the potential of the newly discovered bacterium Candidatus Venantispira tubingensis. It has a broad prey spectrum and could thus provide a natural way to control cyanobacterial blooms in freshwater. This could help reduce ecological damage caused by toxin-producing blooms and protect drinking water reservoirs.

description: Nella fase attuale della forma capitalistica di produzione, comunicazione e produzione coincidono: la comunicazione non riguarda soltanto la fase intermedia tra produzione e consumo, quella dello scambio, ma investe l’intero ciclo produttivo. Precisamente, la comunicazione è oggi produzione, scambio e consumo della comunicazione stessa. La fase finale del consumo è la condizione della ripresa del ciclo produttivo e della sua riproduzione allargata. Già nei primi anni Settanta, Pier Paolo Pasolini aveva colto il carattere distruttivo di questa forma di produzione in cui il consumismo è parte costitutiva, al punto da divenire “stile di vita”; e ne descriveva le conseguenze, via via che essa si andava affermando in quegli anni in Italia, nei termini di una vera propria “mutazione antropologica”degli italiani. Oggi persino l’istruzione e la formazione sono programmate in funzione della comunicazione-produzione, rese funzionali all’ideologia del mercato. Come nei confronti della società produttivistica descritta da Orwell e della sua “neo-lingua”, la scrittura letteraria costituisce oggi una sorta di baluardo nei confronti della comunicazione-produzione e di quella che Pasolini chiamava “lingua comunicativa”. La scrittura letteraria resiste ai processi omologanti e umanamente degradanti della comunicazione globale presentandosi come spazio per l’esercizio di valori quali la creatività, la consapevolezza, la coscienza critica, la responsabilità.

Strain-Induced Topological Magnon Phase Transitions: Applications to Kagome-Lattice Ferromagnets

Year: 2018
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: A common feature of topological insulators is that they are characterized by topologically invariant quantity such as the Chern number and the $\mathbb{Z}_2$ index. This quantity distinguishes a nontrivial topological system from a trivial one. A topological phase transition may occur when there are two topologically distinct phases, and it is usually defined by a gap closing point where the topologically invariant quantity is ill-defined. In this paper, we show that the magnon bands in the strained (distorted) kagome-lattice ferromagnets realize an example of a topological magnon phase transition in the realistic parameter regime of the system. When spin-orbit coupling (SOC) is neglected (i.e. no Dzyaloshinskii-Moriya interaction), we show that all three magnon branches are dispersive with no flat band, and there exists a critical point where tilted Dirac and semi-Dirac point coexist in the magnon spectra. The critical point separates two gapless magnon phases as opposed to the usual phase transition. Upon the inclusion of SOC, we realize a topological magnon phase transition point at the critical strain $δ_c=\frac{1}{2}\big[ 1-(D/J)^2\big]$, where $D$ and $J$ denote the perturbative SOC and the Heisenberg spin exchange interaction respectively. It separates two distinct topological magnon phases with different Chern numbers for $δδ_c$. The associated anomalous thermal Hall conductivity develops an abrupt change at $δ_c$, due to the divergence of the Berry curvature in momentum space. The proposed topological magnon phase transition is experimentally feasible by applying external perturbations such as uniaxial strain or pressure.

description: The micro-environment of cancer cells in the body is mechanically stiffer than that of normal cells. This phenomenon may alter cellular features. We cultured three breast cell lines of MCF10A-normal, MCF7-noninvasive, and MDA-MB-231-invasive on PDMS substrates with elastic moduli of 640kpa, 40kpa and 10kpa, and examined alterations in morphology, cell area, actin structure, cell motility and gene expression caused by substrate stiffness among three cell lines. Effects of substrate stiffness on cell behavior were evident among all examined cell lines. The average cell proliferation was magnified 2.2, 1.5 and 1.6 folds when MCF10A, MCF7 and MDA-MB-231 cells were respectively cultured on stiff substrates compared to soft substrates. Cancerous cells were more sensitive to substrate stiffness for cell behaviors that are related to cell motility and migration which are necessary for invasion. The invasive cancerous cells had the highest sensitivity to all motility parameters and were the most motile on substrates with moderate stiffness followed by non-invasive cancerous cells. The speed of MDA-MB-231 cells raised significantly on the substrate with moderate stiffness, indicating 3-folds higher speeds compared to the cells on the stiff substrates. Distinct actin structures were observed for cells cultured on substrates with different stiffness values necessary for their cell-substrate interaction and migration. Normal cells were least sensitive to substrate stiffness for motility related parameters, however they were more sensitive to cell spreading as an indication of firm adhesion of normal breast cells compared to cancerous cells. IntegrinB1 and E-cadherin were enhanced due to the increased stiffness. Other cell-substrate and cell-cell adhesive markers varied by substrate stiffening. Other cell markers that were related to the biological behaviors such as ECM protease, matrix degradation and cancer progression and cell filopodia (Moesin, Mitogen-activated protein kinases, Matrix metalloproteinases, and human epidermal growth factor receptor2) were also affected by substrate stiffness. Their alterations induced by substrate stiffness were generally according to the analyzed cell movement parameters. Results suggest that alterations in matrix stiffness may be related to cancer disease and its progress.

description: We discuss solution generating techniques treating stationary and axially symmetric metrics in the presence of a cosmological constant. Using the recently found extended form of Ernst's complex equation, which takes into account the cosmological constant term, we propose an extension of spheroidal coordinates adapted to asymptotically de-Sitter and anti de-Sitter static spacetimes. In the absence of a cosmological constant we show in addition that any higher dimensional metric parametrised by a single angular momentum can be given by a 4 dimensional solution and Weyl potentials parametrising the extra Killing directions. We explicitly show how a stationary, and a static axially symmetric spacetime solution in 4 dimensions, can be {\it added} together to give a 5 dimensional stationary and axisymmetric solution.

description: A cactus graph is a connected graph in which every block is either an edge or a cycle. In this paper, we will examine cactus graphs where all the blocks are $3$-cycles, i.e., triangular cactus graphs, of diameter $4$. Our main focus is to prove that the corresponding edge ring of this family of graphs is not normal and satisfies Serre's condition $(S_2)$. We use a criterion due to Katthän for non-normal affine semigroup rings.

description: L'Ateneo di Udine, particolarmente attento al paradigma dell'innovazione continua e alle sollecitazioni del mondo esterno, non ha disatteso le pressanti richieste di formazione permanente e di educazione degli adulti (il /lifelong learning/) e, a partire dall' a.a. 2002/2003, ha aperto il corso di laurea in Relazioni pubbliche /on line/ o Rpol (classe di «Scienze della Comunicazione») della Facoltà di Lingue e letterature straniere ad accesso limitato (75 posti per le immatricolazioni), una proposta formativa parallela a quella in modalità tradizionale con sede a Gorizia, uno dei poli territoriali dell'Ateneo di Udine. Obiettivo di questo lavoro è di illustrare le caratteristiche del corso di laurea, gli aspetti metodologici e tecnologici della didattica nell'aula virtuale, la riconfigurazione della figura del docente e la tipologia di studente che si immatricola. Rpol è stato in grado di intercettare una utenza nuova, costituita da studenti adulti, che sentono la necessità di iniziare una nuova avventura culturale e di acquisire nuove conoscenze che li rendano competitivi in una società in evoluzione continua. Il corso, che si regge su un progetto di qualità è, per ora, un hapax nel mondo accademico udinese, una 'storia di successo' certamente in grado di rappresentare un modello per l'apertura di altri corsi universitari impartiti in modalità /e-learning/.

description: Abstract Esponiamo in questo articolo una sintesi di parte della nostra ricerca1 in relazione all’analisi del contatto fra la lingua degli alunni di origine araba e l’italiano. Il lavoro di ricerca aveva fra gli scopi quello di delineare un’ipotesi concreta su quale fosse il ruolo della L1 nel causare gli errori in L2, quale grado di incidenza avesse e per quale tipo di errori. In relazione a quanto esaminato e valutando gli intrecci fra le diverse teorie sull’analisi del contatto, sulla formazione e sullo sviluppo dell’interlingua e sulla processabilità, abbiamo tratto oltre ad alcune ipotesi di spiegazione delle cause e anche alcune implicazioni glottodidattiche.

A solution to the $γγ^*\rightarrowη_c$ puzzle using the Principle of Maximum Conformality

description: The next-to-next-to-leading order (NNLO) pQCD prediction for the $γγ^* \to η_c$ form factor was evaluated in 2015 using nonrelativistic QCD (NRQCD). A strong discrepancy between the NRQCD prediction and the BaBar measurements was observed. Until now there has been no solution for this puzzle. In this paper, we present a NNLO analysis by applying the Principle of Maximum Conformality (PMC) to set the renormalization scale. By carefully dealing with the light-by-light diagrams at the NNLO level, the resulting high precision PMC prediction agrees with the BaBar measurements within errors, and the conventional renormalization scale uncertainty is eliminated. The PMC is consistent with all of the requirements of the renormalization group, including scheme-independence. The application of the PMC thus provides a rigorous solution for the $γγ^* \to η_c$ form factor puzzle, emphasizing the importance of correct renormalization scale-setting. The results also support the applicability of NRQCD to hard exclusive processes involving charmonium.

title: A Comparative Note on the Bangla Particle "to" and the German Particle "doch"

description: The Bangla discourse particle –to and the German discourse particle doch share a number of syntactic and semantic properties. Their phonetic similarity suggests a remote historical relation. While the latter part will only be mentioned and must remain for the specialists in Indo-European reconstruction, the present short study will highlight points of convergence between the two languages with respect to these particles along a series of concrete tests. The convergence appears to be more than accidental.

description: The screening of Parkinson's Disease (PD) through speech is hindered by a notable lack of publicly available datasets in different languages. This fact limits the reproducibility and further exploration of existing research.
 To address this gap, this manuscript presents the NeuroVoz corpus consisting of 112 native Castilian-Spanish speakers, including 58 healthy controls and 54 individuals with PD, all recorded in ON state. The corpus showcases a diverse array of speech tasks: sustained vowels; diadochokinetic tests; 16 Listen-and-Repeat utterances; and spontaneous monologues.
 The dataset is also complemented with subjective assessments of voice quality performed by an expert according to the GRBAS scale (Grade/Roughness/Breathiness/Asthenia/Strain), as well as annotations with a thorough examination of phonation quality, intensity, speed, resonance, intelligibility, and prosody.
 The corpus offers a substantial resource for the exploration of the impact of PD on speech. This data set has already supported several studies, achieving a benchmark accuracy of 89% for the screening of PD. Despite these advances, the broader challenge of conducting a language-agnostic, cross-corpora analysis of Parkinsonian speech patterns remains open.

description: Hidden conformal symmetries of scalar field on various black hole backgrounds have been investigated for years, but whether those features holds for other fields are still open questions. Recently, with proper assumptions, Lunin achieves to the separation of variables for Maxwell equations on Kerr background. In this paper, with that equation, we find that hidden conformal symmetry appears at near region under low frequency limit. We also extended those results to vector field on Kerr-(A)dS and Kerr-NUT-(A)dS backgrounds, then hidden conformal symmetry also appears if we focusing on the near-horizon region at low frequency limit.
