description: Poster presented in the XVI Scientific Meeting of the Spanish Astronomical Society
description: Distance is one of the most important yet hard to determine measures in astronomy. Many methods such as parallax, Type Ia supernova and Cepheid variables have turned astronomy into astrophysics. Active Galactic Nuclei (AGN) are amongst the most luminous objects in the universe and have long been desired as a distance measure. By analyzing radio flares in AGN jets we can use causality arguments to calibrate a standard ruler. This is then compared against the apparent sizes as measured using Very Long Baseline Interferometry (VLBI).  A ‘Causality Distance’ can then be estimated. This approach is being adopted in the Cosmological Quasar Observations on the KVN from Korea to Australia and South Africa (QUOKKAS) project, which is currently observing ~50 AGN weekly in a redshift range 0 < z < 5. We have applied this technique to archival MOJAVE (Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments) data to determine how best to actually use the method. 15 sources were selected and their angular diameter distances were determined (using the Causality Distance method) and then compared against a standard cosmological model. In this way, we estimate our statistical and systematic uncertainties and find that we could be competitive with other distance measures within 5-10 years of observations.

description: The GN model of non-linear fiber propagation has been shown to overestimate the variance of non-linearity due to the signal Gaussianity approximation, leading to maximum reach predictions for realistic optical systems which may be pessimistic by about 5% to 15%, depending on fiber type and system set-up. Analytical corrections have been proposed, which however substantially increase the model complexity. In this paper we provide a simple closed-form GN model correction formula, derived from the EGN model, which we show to be quite effective in correcting for the GN model tendency to overestimate non-linearity. The formula also permits to clearly identify the correction dependence on key system parameters, such as span length and loss.

We prove that Connes' pairing of some invertible element with Roe's cyclic one-cocycle coincides to the Fredholm index of a Toeplitz operator. In the proof of this paper, we use some properties of a circle and use Higson's argument. In the last section, there is a example of partitioned manifold, which is not a cylinder, with non-trivial pairing.

description: This thesis investigates the psychological impact of chanting practices across traditions, an area that has received little scientific attention to date. Despite the global and historical prevalence of chanting, its psychosocial and psychospiritual effects are poorly understood. Even less understood are the effects of new online chanting formats which have emerged with technological advances and the need to move communal practices online during the COVID-19 pandemic. To understand the effects of live and online chanting, data were gathered worldwide from both experienced and novice chanters through a series of online surveys and interventions. The project aimed to uncover mechanisms of chanting that trigger altered states of consciousness (e.g., mystical states, flow, ego dissolution) and lead to pro-social outcomes. Four research questions were investigated: (1) What is the prevalence and nature of mystical experiences across traditions and practices? (2) Are different chanting styles and belief systems associated with different psychosocial benefits? (3) Isoline chanting an effective tool at reducing stress and increasing social connection? (4) Do the effects of chanting differ for experienced chanters compared to novices? A series of investigations revealed, among other results, that (a) 60% of participants from various traditions (e.g., Hindu, Vedic, Buddhism, Hare Krishna, Tantra, Yoga, Kirtan, etc.) experienced mystical states while chanting; (b) absorption, altruism and religiosity were higher among those who reported mystical states; (c) practitioners who valued devotion and setting intentions for chanting had higher mindfulness scores, experienced greater flow, and higher perceived quality of life; (d) online individual and group chanting interventions led to reduced stress and increased positive affect. These and other findings reported in the thesis shed light on the psychological processes by which chanting practices across diverse traditions can impact upon emotional experience, social connection, wellbeing, and altered states of consciousness.

description: We study metrics on shape space of immersions that have a particularly simple horizontal bundle. More specifically, we consider reparametrization invariant Sobolev metrics $G$ on the space $\operatorname{Imm}(M,N)$ of immersions of a compact manifold $M$ in a Riemannian manifold $(N,\overline{g})$. The tangent space $T_f\operatorname{Imm}(M,N)$ at each immersion $f$ has two natural splittings: one into components that are tangential/normal to the surface $f$ (with respect to $\overline{g}$) and another one into vertical/horizontal components (with respect to the projection onto the shape space $B_i(M,N)=\operatorname{Imm}(M,N)/\operatorname{Diff}(M)$ of unparametrized immersions and with respect to the metric $G$). The first splitting can be easily calculated numerically, while the second splitting is important because it mirrors the geometry of shape space and geodesics thereon. Motivated by facilitating the numerical calculation of geodesics on shape space, we characterize all metrics $G$ such that the two splittings coincide. In the special case of planar curves, we show that the regularity of curves in the metric completion can be controlled by choosing a strong enough metric within this class. We demonstrate in several examples that our approach allows us to efficiently calculate numerical solutions of the boundary value problem for geodesics on shape space.

description: The formation of electron pairs is a prerequisite of superconductivity. The fermionic nature of electrons yields four classes of superconducting correlations with definite symmetry in spin, space and time. Here, we suggest double quantum dots coupled to conventional s-wave superconductors in the presence of inhomogeneous magnetic fields as a model system exhibiting unconventional pairing. Due to their small number of degrees of freedom, tunable by gate voltages, quantum-dot systems provide an ideal tool to gain fundamental insight in unconventional pairing. We propose two detection schemes for unconventional superconductivity, based on either Josephson or Andreev spectroscopy.

description: Synchronized aggregate signature is a special type of signature that all signers have a synchronized time period and allows aggregating signatures which are generated in the same period. This signature has a wide range of applications for systems that have a natural reporting period such as log and sensor data, or blockchain protocol. In CT-RSA 2016, Pointcheval and Sanders proposed the new randomizable signature scheme. Since this signature scheme is based on type-3 pairing, this signature achieves a short signature size and efficient signature verification. In this paper, we design the Pointchcval-Sanders signature-based synchronized aggregate signature scheme and prove its security under the generalized Pointcheval-Sanders assumption in the random oracle model. Our scheme offers the most efficient aggregate signature verification among synchronized aggregate signature schemes based on bilinear groups.

Remarks. Amiarus fulvus comb. nov. is one of the few Pentastirini recorded from Brazil. The species was sparsely described by Walker from a specimen collected in Santarem. The specimen (Fig. 37), deposited at the BMNH, is a female. Although generic placement is difficult without the male terminalia, the species is consistent in habitus with Amiarus subgen. nov. based on its size, form of the vertex and thorax, and the lack of tubercles on the CuP vein. We tentatively place the species in Amiarus subgen. nov. All other described members of Amiarus subgen. nov. are South American in distribution.

description: In the context of supersymmetric models where the gauginos may have both Majorana and Dirac masses we investigate the general constraints from flavour-changing processes on the scalar mass matrices. One finds that the chirality-flip suppression of flavour-changing effects usually invoked in the pure Dirac case holds in the mass insertion approximation but not in the general case, and fails in particular for inverted hierarchy models. We quantify the constraints in several flavour models which correlate fermion and scalar superpartner masses. We also discuss the limit of very large Majorana gaugino masses compared to the chiral adjoint and Dirac masses, where the remaining light eigenstate is the "fake" gaugino, including the consequences of suppressed couplings to quarks beyond flavour constraints.

description: Abstract: Tajikistan, a pivotal country in Central Asia, faces considerable challenges due to climate change, particularly concerning its glaciers, which contribute to 60% of the region's water resources. This article examines the impact of glacier melting on water resources in Central Asia and highlights Tajikistan's strategies to tackle these challenges. It reviews national policies such as the Green Economy Strategy (2023-2037) and international initiatives like the UN’s declaration of 2025 as the International Year of Glacier Protection. The study discusses Tajikistan’s role in regional and global climate advocacy, its collaboration with neighboring Central Asian countries, and its efforts to enhance renewable energy utilization. The findings underscore the urgent need for increased regional cooperation and international support to ensure sustainable water management and climate resilience.

description: We study coherence and entanglement properties of the state space of a composite bi-fermion (two electrons pierced by $λ$ magnetic flux lines) at one Landau site of a bilayer quantum Hall system. In particular, interlayer imbalance and entanglement (and its fluctuations) are analyzed for a set of $U(4)$ coherent (\emph{quasiclassical}) states generalizing the standard pseudospin $U(2)$ coherent states for the spin-frozen case. The interplay between spin and pseudospin degrees of freedom opens new possibilities with regard to the spin-frozen case. Actually, spin degrees of freedom make interlayer entanglement more effective and robust under perturbations than in the spin-frozen situation, mainly for a large number of flux quanta $λ$. Interlayer entanglement of an equilibrium thermal state and its dependence with temperature and bias voltage is also studied for a pseudo-Zeeman interaction.

description: The orbital angular momentum (OAM) of light is potentially interesting for astronomical study of rotating objects such as black holes, but the effect of reduced spatial coherence of astronomical light sources such as stars is largely unknown. In a lab-scale experiment, we find that the detected OAM spectrum depends strongly on the position of the light-twisting object along the line of sight. We develop a simple intuitive model to predict the influence of reduced spatial coherence in astronomical observations, and discuss line-of-sight and intensity issues.

description: Understanding the relation between underlying matter distribution and biased tracers such as galaxy or dark matter halo is essential to extract cosmological information from ongoing or future galaxy redshift surveys. At sufficiently large scales such as the BAO scale, a standard approach for the bias problem on the basis of the perturbation theory (PT) is to assume the `local bias' model in which the density field of biased tracers is deterministically expanded in terms of matter density field at the same position. The higher-order bias parameters are then determined by combining the power spectrum with higher-order statistics such as the bispectrum. As is pointed out by recent studies, however, nonlinear gravitational evolution naturally induces nonlocal bias terms even if initially starting only with purely local bias. As a matter of fact, previous works showed that the second-order nonlocal bias term, which corresponds to the gravitational tidal field, is important to explain the characteristic scale-dependence of the bispectrum. In this paper we extend the nonlocal bias term up to third order, and investigate whether the PT-based model including nonlocal bias terms can simultaneously explain the power spectrum and the bispectrum of simulated halos in $N$-body simulations. We show that the power spectrum, including density and momentum, and the bispectrum between halo and matter in $N$-body simulations can be simultaneously well explained by the model including up to third-order nonlocal bias terms up to k~0.1h/Mpc. Also, the results seem in a good agreement with theoretical predictions of a simple coevolution picture, although the agreement is not perfect. These demonstration clearly shows a failure of the local bias model even at such large scales, and we conclude that nonlocal bias terms should be consistently included in order to model statistics of halos.

description: The first generation of stars produces a background of Lyman-Werner (LW) radiation which can photo-dissociate molecular hydrogen, increasing the mass of dark matter halos required to host star formation. Previous studies have determined the critical mass required for efficient molecular cooling with a constant LW background. However, the true background is expected to increase rapidly at early times. Neglecting this evolution could underestimate star formation in small halos that may have started to cool in the past when the LW intensity was much lower. Background evolution is a large source of uncertainty in pre-reionization predictions of the cosmological 21cm signal, which can be observed with future radio telescopes. To address this, we perform zero-dimentional one-zone calculations that follow the density, chemical abundances, and temperature of gas in the central regions of dark matter halos, including hierarchical growth and an evolving LW background. We begin by studying the physics of halos subjected to a background that increases exponentially with redshift. We find that when the intensity increases more slowly than $J_{\rm LW}(z) \propto 10^{-z/5}$, cooling in the past is a relatively small effect. We then self-consistently compute the cosmological LW background over $z=15-50$ and find that cooling in the past due to an evolving background has a modest impact. Finally, we compare these results to three-dimensional hydrodynamical cosmological simulations with varying LW histories. While only a small number of halos were simulated, the results are consistent with our one-zone calculations.

description: We study the effects of quantum entanglement on the performance of two classical zero-error communication tasks among multiple parties. Both tasks are generalizations of the two-party zero-error channel-coding problem, where a sender and a receiver want to perfectly communicate messages through a one-way classical noisy channel. If the two parties are allowed to share entanglement, there are several positive results that show the existence of channels for which they can communicate strictly more than what they could do with classical resources. In the first task, one sender wants to communicate a common message to multiple receivers. We show that if the number of receivers is greater than a certain threshold then entanglement does not allow for an improvement in the communication for any finite number of uses of the channel. On the other hand, when the number of receivers is fixed, we exhibit a class of channels for which entanglement gives an advantage. The second problem we consider features multiple collaborating senders and one receiver. Classically, cooperation among the senders might allow them to communicate on average more messages than the sum of their individual possibilities. We show that whenever a channel allows single-sender entanglement-assisted advantage, then the gain extends also to the multi-sender case. Furthermore, we show that entanglement allows for a peculiar amplification of information which cannot happen classically, for a fixed number of uses of a channel with multiple senders.

description: The motivic nearby fiber is an invariant obtained from degenerating a complex variety over a disc. It specializes to the Euler characteristic of the original variety but also contains information on the variation of Hodge structure associated to the degeneration which is encoded as a limit mixed Hodge structure. However, this invariant is difficult to compute in practice. Using the techniques of tropical geometry we present a new formula for the motivic nearby fiber. Moreover, since there is a range of available software implementing the main algorithms in tropical geometry, our formula can be computed in practice. We specialize to the case of families of schön complex hypersurfaces of tori where we provide explicit formulas describing the action of the unipotent part of monodromy on the graded pieces (with respect to the Deligne weight filtration) of the cohomology with compact supports. These families are described combinatorially by a polyhedral subdivision of the associated Newton polytope. We develop new mixed Hodge theory-inspired combinatorial invariants of such subdivisions, among them the `refined limit mixed $h^*$-polynomial'. These invariants are related to Stanley's combinatorial study of subdivisions: in a companion combinatorial paper whose results are applied here, we situate our invariants in Stanley's theory where they become multi-variable extensions of his invariants. Our results generalize work of Danilov and Khovanski{\uı} and Batyrev and Borisov on the Hodge numbers of hypersurfaces. We also present analogous formulas describing the action of the unipotent part of monodromy on the intersection cohomology groups of a family of schön hypersurfaces of a projective toric variety.

description: Yang-Mills-Higgs theory offers a rich set of physics. In particular, in some region of its parameter space it has QCD-like behavior, while in some other range it is Higgs-like. Furthermore, for the choice of the gauge group SU(2) and an SU(2) Higgs flavor symmetry it is the Higgs sector of the standard model. Therefore, it is possible to study a plethora of phenomena within a single theory. Here the standard-model version is studied using lattice gauge theory. Choosing non-aligned minimal Landau gauge, its propagators and three-point vertices will be determined in both the QCD-like and Higgs-like domains. This permits to test various proposals for how confinement works, as well as how confinement and the Higgs effect differ. The correlations functions are found to exhibit a different behavior, depending on whether the lowest mass scalar flavor singlet is lighter than the vector triplet, heavier and stable, or unstable against decay into two vector triplets.

description: We prove new kinematic formulas for tensor valuations and simplify previously known Crofton formulas by using the recently developed algebraic theory of translation invariant valuations. The heart of the paper is the computation of the Alesker-Fourier transform on the large class of spherical valuations, which is achieved by differential-geometric and representation theoretical tools. We also describe in explicit form the product and convolution of tensor valuations.

Dust Transport in MRI Turbulent Disks: Ideal and Non-ideal MHD with Ambipolar Diffusion

description: We study dust transport in turbulent protoplanetary disks using three-dimensional global unstratified magnetohydrodynamic (MHD) simulations including Lagrangian dust particles. The turbulence is driven by the magnetorotational instability (MRI) with either ideal or non-ideal MHD that includes ambipolar diffusion (AD). In ideal MHD simulations, the surface density evolution (except for dust that drifts fastest), turbulent diffusion, and vertical scale height of dust can all be reproduced by simple one-dimensoinal and/or analytical models. However, in AD dominated simulations which simulate protoplanetary disks beyond 10s of AU, the vertical scale height of dust is larger than previously predicted. To understand this anomaly in more detail, we carry out both unstratified and stratified local shearing box simulations with Lagrangian particles, and find that turbulence in AD dominated disks has very different properties (e.g., temporal autocorrelation functions and power spectra) than turbulence in ideal MHD disks, which leads to quite different particle diffusion efficiency. For example, MRI turbulence with AD has a longer correlation time for the vertical velocity, which causes significant vertical particle diffusion and large dust scale height. In ideal MHD the Schmidt numbers ($Sc$) for radial and vertical turbulent diffusion are $Sc_{r}\sim 1$ and $Sc_{z}\gtrsim 3$, but in the AD dominated regime both $Sc_{r}$ and $Sc_{z}$ are $\lesssim 1$. Particle concentration in pressure bumps induced by MRI turbulence has also been studied. Since non-ideal MHD effects dominate most regions in protoplanetary disks, our study suggests that modeling dust transport in turbulence driven by MRI with non-ideal MHD effects is important for understanding dust transport in realistic protoplanetary disks.

description: The nucleation of reversed magnetic domains in Pt/Co/AlO$_{x}$ microstructures with perpendicular anisotropy was studied experimentally in the presence of an in-plane magnetic field. For large enough in-plane field, nucleation was observed preferentially at an edge of the sample normal to this field. The position at which nucleation takes place was observed to depend in a chiral way on the initial magnetization and applied field directions. An explanation of these results is proposed, based on the existence of a sizable Dzyaloshinskii-Moriya interaction in this sample. Another consequence of this interaction is that the energy of domain walls can become negative for in-plane fields smaller than the effective anisotropy field.

Orbital ordering transition in the single-layer manganites near half doping: a weak-coupling approach

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

description: The roles of crystal-field splitting and Jahn-Teller distortions on the orbital ordering transition are investigated in the single-layer manganites near half doping. Crystal-field splitting of energy levels favoring the $d_{3z^2-r^2}$ occupancy provides not only the correct Fermi surface topology for La$_{0.5}$Sr$_{1.5}$MnO$_4$ having a circular electron pocket around the $Γ$ point, but also enhances the flatness of the hole pocket around the M point thereby improving the nesting. In the presence of the circular electron pocket, Jahn-Teller distortions are found to be crucial for the transition to the transverse orbital ordering with ordering wavevector ($0.5π, 0.5π$). In the hole-doping regime $0.5 \leq x \leq 0.7$, the orbital ordering wavevector shows a linear dependence on the hole concentration in accordance with the experiments.

description: The utilization and demand of self-medication with herbomineral-based formulations have increased day-by-day across the globe over the last decade. A new proprietary herbomineral formulation was prepared with the mixture of minerals (zinc, magnesium, and selenium) and the herbal root extract of ashwagandha. The current study was undertaken to evaluate the Biofield Energy Healing (The Trivedi Effect®) on the test herbomineral formulation using murine dendritic cells (DCs) and splenocytes in vitro. The formulation was divided into two parts, one part was control without any Biofield Energy Treatment, while the other part was defined as the Biofield Energy Treated sample, which received the Biofield Energy Healing Treatment remotely from eighteen renowned Biofield Energy Healers. The effect of the Biofield Energy Treated formulation in murine cells was monitored with an estimation of pro-inflammatory cytokines levels such as tumor necrosis factor (TNF-α), macrophage inflammatory protein-1α (MIP-1α) and interleukin (IL-1β) in cell culture supernatants along with estimations of non-cytotoxic concentrations of the test formulation by MTT assay. The Biofield Treated formulation showed 114.2%, 122.6%, 141.2%, 127.8%, and 114.1% cell viability at concentrations 1.05, 5.2, 10.5, 25.6, and 51.2 µg/mL, respectively in DCs. Similarly, the Biofield Energy Treated and untreated formulations showed more than 100% cell viability in mice splenocytes at 5 µg/mL. The level of TNF-α in DCs was significantly (p≤0.05) inhibited by 19.21% in the Biofield Treated formulation at concentration 5.2 µg/mL as compared to the untreated test formulation. The level of MIP-1α in LPS induced mice splenocyte cells was reduced by 15.35% in the Biofield Energy Treated formulation at 0.0105 µg/mL as compared to the untreated formulation. Similarly, the level of IL-1β in LPS induced mice splenocyte cells was significantly (p≤0.05) reduced by 31.59% in the Biofield Treated formulation at 1.05 µg/mL as compared to the untreated formulation. Altogether, the results suggest that The Trivedi Effect® (Biofield Energy Healing Treatment) showed significant down-regulation of the tested pro-inflammatory cytokines expression and potentiated the immunosuppressive effect of the treated formulation to modulate the immune system. These data also suggest that the Biofield Treated test formulation can be used for autoimmune and inflammatory diseases, stress management and anti-aging by improving overall health.
