Interface dynamics for layered structures

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We investigate dynamics of large scale and slow deformations of layered structures. Starting from the respective model equations for a non-conserved system, a conserved system and a binary fluid, we derive the interface equations which are a coupled set of equations for deformations of the boundaries of each domain. A further reduction of the degrees of freedom is possible for a non-conserved system such that internal motion of each domain is adiabatically eliminated. The resulting equation of motion contains only the displacement of the center of gravity of domains, which is equivalent to the phase variable of a periodic structure. Thus our formulation automatically includes the phase dynamics of layered structures. In a conserved system and a binary fluid, however, the internal motion of domains turns out to be a slow variable in the long wavelength limit because of concentration conservation. Therefore a reduced description only involving the phase variable is not generally justified.

description: The formulation of Brans-Dicke (BD) gravity with matter in the Einstein frame is realized as Einstein gravity with dilaton and dilaton coupled matter. We calculate the one-loop 4d anomaly-induced effective action due to N dilaton- coupled massless fermions on the time-dependent conformally flat background with non-trivial dilaton. Using that complete effective action the (fourth-order) quantum corrected equations of motion are derived. One special solution of these equations representing an inflationary Universe (with exponential scale factor) and (much slower) expanding BD dilaton is given. Similarly, the 2d quantum BD Universe with time-dependent dilaton is constructed. In the last case the dynamics is completely due to quantum effects.

description: We characterize the incidence and intensity of low-level super-massive black hole activity within the Fornax cluster, through X-ray observations of the nuclei of 29 quiescent early-type galaxies. Using the \textit{Chandra X-ray Telescope}, we target 17 galaxies from the HST Fornax Cluster Survey, down to a uniform (3$σ$) limiting X-ray luminosity threshold of $5\cdot10^{38}$ergs$^{-1}$, which we combine with deeper, archival observations for an additional 12 galaxies. A nuclear X-ray point-source is detected in 11 out of 29 targets. After accounting for the low mass X-ray binary contamination to the nuclear X-ray signal, the X-ray active fraction is measured at $26.6\% \pm 9.6\%$. The results from this analysis are compared to similar investigations targeting quiescent early types in the Virgo cluster, as well as the field. After correcting for the different mass distributions, the measured Fornax active fraction is less than the field fraction, at more than 3$σ$, confirming that the funneling of gas to the nuclear regions of cluster members is inhibited compared to those galaxies in the field. At the same time, we find no statistically significant difference between Fornax and Virgo galaxies, with only marginal evidence for a lower active fraction in Fornax (1 $σ$); if real, owing to Fornax's higher galaxy number density, this could indicate that galaxy-galaxy interactions are more effective at gas removal than galaxy-gas effects.

description: Assuming that $X(3872)$ is a mixture between $2P$ charmonium and $\bar{D}D^{*}$ molecular states with $J^{PC}=1^{++}$, an analysis of $X(3872)$ radiative decays into $J/ψγ$ and $ψ(2S)γ$ is presented. The modification of the radiative branching ratio due to possible constructive or destructive interferences between the meson-loop and the short-distance contact term, which is modeled by a charm quark loop, is shown. The model predictions are shown to be compatible with the experimentally determined ratio of the mentioned branching fractions for a wide range of the $X(3872)$ charmonium content. In the case of the destructive interference, a strong restriction on the charmonium admixture is found.

Reachability Analysis of Pushdown Systems with an Upper Stack

description: Pushdown systems (PDSs) are a natural model for sequential programs, but they can fail to accurately represent the way an assembly stack actually operates. Indeed, one may want to access the part of the memory that is below the current stack or base pointer, hence the need for a model that keeps track of this part of the memory. To this end, we introduce pushdown systems with an upper stack (UPDSs), an extension of PDSs where symbols popped from the stack are not destroyed but instead remain just above its top, and may be overwritten by later push rules. We prove that the sets of successors post* and predecessors pre* of a regular set of configurations of such a system are not always regular, but that post* is context-sensitive, so that we can decide whether a single configuration is forward reachable or not. In order to under-approximate pre* in a regular fashion, we consider a bounded-phase analysis of UPDSs, where a phase is a part of a run during which either push or pop rules are forbidden. We then present a method to over-approximate post* that relies on regular abstractions of runs of UPDSs. Finally, we show how these approximations can be used to detect stack overflows and stack pointer manipulations with malicious intent.

description: “Juchowo Farm” is a large-scale farm in North-Western Poland near Szczecinek, established in 2000, operating on nearly 2,000 hectares of land. It is one of the best examples of a multifunctional farm in Poland and is a forerunner in the introduction of modern agroforestry practices in this part of Europe. “Juchowo Farm” is a biodynamic farm with a strongly diversified agricultural production. It consists of 1,450 ha of arable land, 340 ha of grasslands, 140 ha of forests and trees outside forests and 7.5 ha of vegetables garden (2016). The main source of income for the farm is the production and sale of biodynamic milk. Almost 700 head of cattle are kept here. Additionally, 77 other biodynamic products are sold directly at the farm, including different types of bread, cheese, herbs, fruit syrups and vegetables.
Do naked singularities generically occur in generalized theories of gravity?

description: A new mechanism for causing naked singularities is found in an effective superstring theory. We investigate the gravitational collapse in a spherically symmetric Einstein-Maxwell-dilaton system in the presence of a pure cosmological constant "potential", where the system has no static black hole solution. We show that once gravitational collapse occurs in the system, naked singularities necessarily appear in the sense that the field equations break down in the domain of outer communications. This suggests that in generalized theories of gravity, the non-minimally coupled fields generically cause naked singularities in the process of gravitational collapse if the system has no static or stationary black hole solution.

description: It is widely believed that the primary X-ray emission of AGN is due to the Comptonisation of optical-UV photons from a hot electron corona, while the origin of the 'soft-excess' is still uncertain and matter of debate. A second Comptonisation component, called warm corona, was therefore proposed to account for the soft-excess, and found in agreement with the optical-UV to X-ray emission of a sample of Seyfert galaxies. In this context, we exploit the broadband XMM-Newton and NuSTAR simultaneous observations of the Seyfert galaxy NGC 4593 to further test the so called "two corona model". The NGC 4593 spectra are well reproduced by the model, from the optical/UV to the hard X-rays. Moreover, the data reveal a significant correlation between the hot and the warm corona parameters during our monitoring campaign.

We calculate the correlation functions via the Landau-Ginzburg formulation and derive the string equation based on the twistor construction. Moreover, by using the approach of Dubrovin and Zhang, we compute the genus one correction of the Poisson brackets and compare them with the Oevel-Strampp's brackets of the Kaup-Broer hierarchy.

description: Abstract

Vitamin D plays a critical role in maintaining overall health, particularly in bone metabolism, immune function, and respiratory health. This study examines the relationship between vitamin D status and asthma among young adult women in Baidoa, Somalia. The research aims to assess the impact of vitamin D deficiency on asthma prevalence, severity, and respiratory function in young women.

Using a cross-sectional study design, data was collected through surveys, medical assessments, and laboratory tests from young adult women diagnosed with asthma. The findings indicate that a significant proportion of participants suffer from vitamin D deficiency, which is associated with increased asthma symptoms and reduced lung function. Factors contributing to low vitamin D levels include limited sun exposure, poor dietary intake, and lack of awareness regarding vitamin D’s health benefits.

The study highlights the need for targeted interventions, including vitamin D supplementation, public health awareness campaigns, and improved dietary strategies to enhance vitamin D levels among young women. Recommendations include incorporating vitamin D screening into routine asthma management, encouraging sun exposure, and promoting balanced diets rich in vitamin D sources. These findings provide valuable insights for healthcare providers, policymakers, and researchers working to improve respiratory health and nutrition in Somalia.

description: Organic-inorganic halide perovskites recently have emerged as a promising material for highly effective light-emitting diodes (LEDs) and solar cells (SCs). Despite efficiencies of both perovskite SCs and LEDs are already among the best, the development of a perovskite dual functional device that is capable of working in these two regimes with high efficiencies is still challenging. Here we demonstrate that the dual functional device based on mixed halide perovskite CH3NH3PbBr2I can be switched from SC to LED with low threshold voltage Vth < 2 V by exposing to Sun at open circuit Voc or at small bias voltage of Vpol ~ 1 - 2 V. Such photo-poling creates in-situ p-i-n junction via methylammonium (CH3NH3+, MA+) and I-/Br- ions migration to interfaces, lowering charge injection barriers, and self-balancing injection currents in perovskite LED. We show that before the photo-poling, the electroluminescence (EL) is highly unstable in LED regime, whereas after the photo-poling, stabilized EL exhibits unusual dynamics, increasing with time and poling cycle number, while Vth and injection current decrease with cycling runs. Additionally, photo-induced and current-induced halide segregation accumulates with cycling, that is found beneficial for LED, increasing its efficiency and brightness, but reversibly degrading photovoltaic (PV) performance, which can be easily recovered.

description: We present an asymptotic analysis of the Gunn effect in a drift-diffusion model---including electric-field-dependent generation-recombination processes---for long samples of strongly compensated p-type Ge at low temperature and under dc voltage bias. During each Gunn oscillation, there are different stages corresponding to the generation, motion and annihilation of solitary waves. Each stage may be described by one evolution equation for only one degree of freedom (the current density), except for the generation of each new wave. The wave generation is a faster process that may be described by solving a semiinfinite canonical problem. As a result of our study we have found that (depending on the boundary condition) one or several solitary waves may be shed during each period of the oscillation. Examples of numerical simulations validating our analysis are included.

description: The switching dynamics of a single-domain BiFeO$_3$ thin films is investigated through combining the dynamics of polarization and Neel vector. The evolution of the ferroelectric polarization is described by the Landau-Khalatnikov (LK) equation, and the Landau-Lifshitz-Gilbert (LLG) equations for spins in two sublattices to model the time evolution of the antiferromagnetic order (Neel vector) in a G-type antiferromagnet. This work theoretically demonstrates that due to the rotation of the magnetic hard axis following the polarization reversal, the Neel vector can be switched by 180 degrees, while the weak magnetization can remain unchanged. The simulation results are consistent with the ab initio calculation, where the Neel vector rotates during polarization rotation, and also match our calculation of the dynamics of order parameter using Landau-Ginzburg theory. We also find that the switching time of the Neel vector is determined by the speed polarization switching and is predicted to be as short as 30 ps.

description: The farm in Gunarsholt is located 100 km East from Reykjavík, nearby Hella city and belongs to the governmental agency – Soil Conservation Service (SCS) which is world’s oldest agency with soil protection and reclamation mission (1907). The farm includes several minor households and covers 8000 ha in total. It was founded in the place where severe erosion and frequent sand storms forced local inhabitants to leave the area in the period 1885-1925. In 1944, Icelandic government purchased the land and undertook efforts to restore the land to the sustainable production. After many years of intensive work, the farm is presently simply submerged in greenness. Of particular interest is its windbreaks design. The belts are characterised by specific structure and include two external rows of lower height vegetation (Salix phylicifolia, Betula pubescens) and one internal row of balsam poplar (Populus tricocarpa).

description: Abstract 

Background: Severe acute malnutrition (SAM) is a life-threatening situation characterized by severe wasting (low weight-for-height) or the presence of nutritional edema due to insufficient consumption of nutrients. WHO standards define SAM as either: 1) no edematous with a weight-for-height z-score (WHZ) below 3 standard deviation (SD) or a mid-upper arm circumference (MUAC) of less than 115 mm; 2) edematous SAM with the presence of bilateral pitting edema, a condition of fluid retention linked to early childhood malnutrition or 3) mixed phenotype with the presence of both wasting and edema.

Objectives: To assess magnitude and associated factors of severe acute malnutrition among under-five children in Hassan Kayd MCH.

Method and material: An institutional-based cross-sectional study was used. Study was conducted in Burao General Hospital. Sampling The Systemic sampling method was used to select the study. Our sample size was 135 participants. Additionally, data was analyzed and interpreted by using statistical tools like 20, table frequency, and percentage.

Result: The Magnitude of Severe Acute Malnutrition among Under-Five Children was 18.5%, while 81.5% was not SAM. Family monthly income with a p-value 0.049, initiation of breastfeeding with a p-value of 0.012, timely complementary feeding starts with a p-value of 0.027, and frequency of taking vegetables and fruits to the children with a p-value of 0.032 was statistically significant SAM among under-five children.

Conclusion: The magnitude of SAM was higher compared to other studies. Family monthly income, initiation of breastfeeding, timely complementary feeding starts, and frequency of taking vegetables and fruits to the children were significantly associated with SAM among under-five children.

Recommendation: Nutritional status screening, increasing the income of the community, early initiation of breastfeeding, adequate and diversity of complementary feeding, and further study were strongly recommended.

description: Photonics might play a key role in future wireless communication systems that operate at THz carrier frequencies. A prime example is the generation of THz data streams by mixing optical signals in high-speed photodetectors. Over the previous years, this concept has enabled a series of wireless transmission experiments at record-high data rates. Reception of THz signals in these experiments, however, still relied on electronic circuits. In this paper, we show that wireless THz receivers can also greatly benefit from optoelectronic signal processing techniques, in particular when carrier frequencies beyond 0.1 THz and wideband tunability over more than an octave is required. Our approach relies on a high-speed photoconductor and a photonic local oscillator for optoelectronic down-conversion of THz data signals to an intermediate frequency band that is easily accessible by conventional microelectronics. By tuning the frequency of the photonic local oscillator, we can cover a wide range of carrier frequencies between 0.03 THz and 0.34 THz. We demonstrate line rates of up to 10 Gbit/s on a single channel and up to 30 Gbit/s on multiple channels over a distance of 58 m. To the best of our knowledge, our experiments represent the first demonstration of a THz transmission link that exploits optoelectronic signal processing techniques both at the transmitter and the receiver.

Exact solution to the homogeneous Maxwell equations in the field of a gravitational wave in linearized theory

description: We present the exact solution to the linearized Maxwell equations in space-time slightly curved by a gravitational wave. We show that in general, even dealing with a first-order theory in the strength of the gravitational field, the solution can not be written as the sum of the flat space-time one and a weak perturbation due to the external field. Such an impossibility arises when either the frequency of the gravitational wave is too low or too high with respect to the one of the electromagnetic field. We also provide an application of the solution to the case of an electromagnetic field bounced between two parallel conducting planes.

description: The recently proposed de Sitter swampland conjecture excludes local extrema of a scalar potential with a positive energy density in a low energy effective theory. Under the conjecture, the observed dark energy cannot be explained by the cosmological constant. The local maximum of the Higgs potential at the symmetric point also contradicts with the conjecture. In order to make the Standard Model consistent with the conjecture, it has been proposed to introduce a quintessence field, $Q$, which couples to the cosmological constant and the local maximum of the Higgs potential. In this paper, we show that such a modified Higgs potential generically results in a $Q$-dependent Higgs vacuum expectation value (VEV). The $Q$-dependence of the Higgs VEV induces a long-range force, which is severely excluded by the tests of the equivalence principle. Besides, as the quintessence field is in motion, the Higgs VEV shows a time-dependence, which is also severely constrained by the measurements of the time-dependence of the proton-to-electron mass ratio. Those constraints require an additional fine-tuning which is justified neither by the swampland conjecture nor the anthropic principle. We further show that, even if such an unjustified fine-tuning condition is imposed at the tree level, radiative corrections upset it. Consequently, we argue that most of the habitable vacua in the string landscape are in tension with the phenomenological constraints.

description: We study the possibility that the vacuum energy density of scalar and internal-space gauge fields arising from the process of dimensional reduction of higher dimensional gravity theories plays the role of quintessence. We show that, for the multidimensional Einstein-Yang-Mills system compactified on a $R \times S^3 \times S^d$ topology, there are classically stable solutions such that the observed accelerated expansion of the Universe at present can be accounted for without upsetting structure formation scenarios or violating observational bounds on the vacuum energy density.

description: We investigate the growth kinetics of binary immiscible fluids and emulsions in two dimensions using a hydrodynamic lattice-gas model. We perform off-critical quenches in the binary fluid case and find that the domain size within the minority phase grows algebraically with time in accordance with theoretical predictions. In the late time regime we find a growth exponent n = 0.45 over a wide range of concentrations, in good agreement with other simluations. In the early time regime we find no universal growth exponent but a strong dependence on the concentration of the minority phase. In the ternary amphiphilic fluid case the kinetics of self assembly of the droplet phase are studied for the first time. At low surfactant concentrations, we find that, after an early algebraic growth, a nucleation regime dominates the late-time kinetics, which is enhanced by an increasing concentration of surfactant. With a further increase in the concentration of surfactant, we see a crossover to logarithmically slow growth, and finally saturation of the oil droplets, which we fit phenomenologically to a stretched exponential function. Finally, the transition between the droplet and the sponge phase is studied.

description: “Darliner” is a small-scale farm constituted in 2010. The farm is located in the southern-west part of Umbria Region, Central Italy. Around the farm, a mosaic of agroforestry systems, at different level of complexity, characterizes the rural landscape. Olive groves, often managed in combination with pasture or intercropped with cereals, and vineyards are the most common agricultural crops on hilly lands. Other crops, such as sunflower and tobacco are cultivated in small portion of plain lands. Agricultural fields are usually alternated with wooded lands with oaks, ash, maple, etc. managed as coppice to produce fuelwood destined to local energy market.

description: We study the random walk of a particle in a compartmentalized environment, as realized in biological samples or solid state compounds. Each compartment is characterized by its length $L$ and the boundaries transmittance $T$. We identify two relevant spatio-temporal scales that provide alternative descriptions of the dynamics: i) the microscale, in which the particle position is monitored at constant time intervals; and ii) the mesoscale, in which it is monitored only when the particle crosses a boundary between compartments. Both descriptions provide --by construction-- the same long time behavior. The analytical description obtained at the proposed mesoscale allows for a complete characterization of the complex movement at the microscale, thus representing a fruitful approach for this kind of systems. We show that the presence of disorder in the transmittances is a necessary condition to induce anomalous diffusion, whereas the spatial heterogeneity reduces the degree of subdiffusion and, in some cases, can even compensate for the disorder induced by the stochastic transmittance.

description: Andrzej Majerski’s farm is an organic family farm in Southern Poland (Małopolska region, Łącko district) of 24 ha which includes 10 ha of arable land (mowing-grazing usage), 1 ha of old orchards, 1.5 of new orchards and 12 ha of forest. The conversion of the farm to an organic system started in 2005 to provide value-added food products and improve farm income at the same time. The farmer is interested in protecting local varieties of apple trees to prevent their disappearance and maintain local cultural identity, but strengthening the competitive position of the agricultural enterprise is also a key priority in the region, where most of the land belongs to smallholders.

description: Many models for chaotic systems consist of joining two integrable systems with incompatible constants of motion. The quantum counterparts of such models have a propagator which factorizes into two integrable parts. Each part can be diagonalized. The two eigenvector bases are related by an orthogonal (or unitary) transformation. We construct a random matrix ensemble that mimics this situation and consists of a product of a diagonal, an orthogonal, another diagonal and the transposed orthogonal matrix. The diagonal phases are chosen at random and the orthogonal matrix from Haar's measure. We derive asymptotic results (dimension N -> \infty) using Wick contractions. A new approximation for the group integration yields the next order in 1/N. We obtain a finite correction to the circular orthogonal ensemble, important in the long-range part of spectral correlations.

Aging and diffusion in low dimensional environments

description: We study out of equilibrium dynamics and aging for a particle diffusing in one dimensional environments, such as the random force Sinai model, as a toy model for low dimensional systems. We study fluctuations of two times $(t_w, t)$ quantities from the probability distribution $Q(z,t,t_w)$ of the relative displacement $z = x(t) - x(t_w)$ in the limit of large waiting time $t_w \to \infty$ using numerical and analytical techniques. We find three generic large time regimes: (i) a quasi-equilibrium regime (finite $τ=t-t_w$) where $Q(z,τ)$ satisfies a general FDT equation (ii) an asymptotic diffusion regime for large time separation where $Q(z) dz \sim \bar{Q}[L(t)/L(t_w)] dz/L(t)$ (iii) an intermediate ``aging'' regime for intermediate time separation ($h(t)/h(t_w)$ finite), with $Q(z,t,t') = f(z,h(t)/h(t')) $. In the unbiased Sinai model we find numerical evidence for regime (i) and (ii), and for (iii) with $\bar{Q(z,t,t')} = Q_0(z) f(h(t)/h(t'))$ and $h(t) \sim \ln t$. Since $h(t) \sim L(t)$ in Sinai's model there is a singularity in the diffusion regime to allow for regime (iii). A directed model, related to the biased Sinai model is solved and shows (ii) and (iii) with strong non self-averaging properties. Similarities and differences with mean field results are discussed. A general approach using scaling of next highest encountered barriers is proposed to predict aging properties, $h(t)$ and $f(x)$ in landscapes with fast growing barriers. We introduce a new exactly solvable model, with barriers and wells, which shows clearly diffusion and aging regimes with a rich variety of functions $h(t)$.
