description: The transfer of information between two physical locations is an essential component of both classical and quantum computing. In quantum computing the transfer of information must be coherent to preserve quantum states and hence the quantum information. We establish a simple protocol for transferring one- and two-electron encoded logical qubits in quantum dot arrays. The theoretical energetic cost of this protocol is calculated - in particular, the cost of freezing and unfreezing tunnelling between quantum dots. Our results are compared with the energetic cost of shuttling qubits in quantum dot arrays and transferring classical information using classical information buses. Only our protocol can manage constant dissipation for any chain length. This protocol could reduce the cooling requirements and constraints on scalable architectures for quantum dot quantum computers.

description: TikTok creators have figured out how to make its users want to consume content and, more importantly, stay on the platform. What may feel like a knowledge bank and a source of harmless entertainment is said to affect the way we view ourselves, how we consume information, and much more (McGowan, 2020).  This thesis project aims to better understand Gen Z’s heightened consumerism patterns inconsistent with their moral beliefs. Reviewing the topics of TikTok, the role of Influencer Marketing, Sustainability in Fashion, and Cognitive Dissonance, this study applies Festinger’s magnitude of post-decision dissonance exposition to find that these Gen Z’s eco-consciousness is a cause of cognitive dissonance when purchasing fashion items on TikTok, especially for those who have a moderate care for protecting the environment. Themes found in responses from the quantitative survey questions paired with the qualitative interview discussions provide a limited, yet fresh perspective that encourages decisions with integrity for both Gen Z consumers and TikTok.

description: If we are ever to unravel the mysteries of brain function at its most fundamental level, we will need a precise understanding of how its component neurons connect to each other. Electron Microscopes (EM) can now provide the nanometer resolution that is needed to image synapses, and therefore connections, while Light Microscopes (LM) see at the micrometer resolution required to model the 3D structure of the dendritic network. Since both the topology and the connection strength are integral parts of the brain's wiring diagram, being able to combine these two modalities is critically important. In fact, these microscopes now routinely produce high-resolution imagery in such large quantities that the bottleneck becomes automated processing and interpretation, which is needed for such data to be exploited to its full potential. In this paper, we briefly review the Computer Vision techniques we have developed at EPFL to address this need. They include delineating dendritic arbors from LM imagery, segmenting organelles from EM, and combining the two into a consistent representation.

description: In this paper, we explore the use of microfluidic paper-based analytical devices (lPADs) to study the behavior of Caenorhabditis elegans. We show how these devices can be fabricated on paper and plastic substrates, as well as how to load, visualize, and transfer single and multiple nematodes. We also demonstrate the use of anthelmintic drug, levamisole, to perform chemical testing on C. elegans. Furthermore, we provide a custom program that is able to recognize individual worms on the lPADs in real-time and extract their locomotion parameters. This combination of lPADs and the nematode tracking program creates a low-cost, easy-to-fabricate imaging and screening assay that is superior to standard agarose plates or polymeric microfluidic devices for non-microfluidic, nematode laboratories.

description: Polymer chains decorated with a fraction of monomers capable of forming reversible bonds form transient polymer networks that are important in soft and biological systems. If chains are flexible and the attractive monomers are all of the same species, the network formation occurs continuously as density increases. By contrast, it has been recently shown [L. Rovigatti and F. Sciortino, Phys. Rev. Lett. 129, 047801 (2022)] that, if the attractive monomers are of two different and alternating types, the entropic gain of swapping intra-molecular bonds for inter-molecular connections induces a first order phase transition in the fully-bonded (\textit{i.e.} low-temperature or, equivalently, large monomer-monomer attraction strength) limit and the network forms abruptly on increasing density. Here we use simulations to show that this phenomenon is robust with respect to thermal fluctuations, disorder and change in the polymer architecture, demonstrating its generality and likely relevance for the wide class of materials that can be modelled as associative (transient) polymer networks.

description: Self-propulsion of catalytic Janus swimmers in electrolyte solutions is induced by inhomogeneous ion release from their surface. Here, we consider the experimentally relevant cases of particles which emit only one type of ions (type I) or equal fluxes of cations and anions (type II). In the limit of a thin electrostatic diffuse layer we derive a nonlinear outer solution for the electric field and concentrations of active (i.e. released from the surface) and passive ionic species. We show that for swimmers of type I both the maximum ion flux and propulsion velocity are constrained. This suggests that the propulsion of Janus swimmers can be optimized by tuning the concentration of active ions.

description: This study experimentally investigates the isotopic behaviors of Li and K during the dissolution of silicate rocks (i.e., basalt and granite). Proton-driven dissolution (in 0.8 M HNO3) and ligand-driven dissolution (in 5 mM critic acid or oxalic acid) experiments were performed in batch-closed systems over 15 days. We provide a time-series interpretation of Li and K isotope fractionation during silicate dissolution in ultra-acidic (unidirectional) and near-natural (biologically affected) environments. As the reaction progressed, we measured large isotope fractionation between the liquid (l) phase and the pristine silicate (s) phase, ranging from −10.3 to 0.1‰ (Δ7Lil-s) and from −1.01 to −0.11‰ (Δ41Kl-s) through the early stage of dissolution (<24 h). The enrichment of lighter Li and K isotopes in the solutions rapidly diminished as rock dissolution continued and gradually approached equilibrium to the end of experiments. In contrast, resorption of pre-leached isotopically lighter Li on silicate residuals during ligand-driven dissolution produced lighter isotope enrichment in the solutions compared to the initial rock by up to 2.8‰. Despite the preferential dissolution of specific minerals, the isotope fractionation patterns of Li and K do not vary with lithology, indicating limited inter-mineral isotopic differences. During the experiments, the Li and K isotopic pattern could be divided into two-to-three stages. The initial enrichment of light isotopes in the liquids can be ascribed to the kinetic isotope effect, confounded by diffusion and ion solvation. A later transition towards no isotope fractionation of Li and K may be explained by (i) the masking effect from dissolution, and (ii) an imprint from the destruction of 7Li/41K-enriched surface layers. Lateral resorption of solute Li after ~100 h reaction could be facilitated by the electrostatic attraction from increasing surface negative charges and active hydroxyls with increasing pH during ligand-driven dissolution (pH ~ 4) relative to proton-driven dissolution (pH ~ 0.2). Therefore, the presence of organic ligands impacts dissolution stoichiometry, and potentially modifies Li isotope fractionation in natural weathering environments. In comparison, K isotope fractionation driven by rock dissolution stops immediately (within days) after starting the experiments. This research helps to understand the mechanisms of Li and K isotope fractionation during chemical weathering and trace long-term climate change using geological records.
Explaining Giant Apparent $\mathrm{p}K_\mathrm{A}$ Shifts in Weak Polyelectrolyte Brushes

description: Recent experiments on weak polyelectrolyte brushes found marked shifts in the effective p$K_\mathrm{A}$ that are linear in the logarithm of the salt concentration. Comparing explicit-particle simulations with mean-field calculations we show that for high grafting densities the salt concentration effect can be explained using the ideal Donnan theory, but for low grafting densities the full shift is due to a combination of the Donnan effect and the polyelectrolyte effect. The latter originates from electrostatic correlations which are neglected in the Donnan picture and which are only approximately included in the mean-field theory. Moreover, we demonstrate that the magnitude of the polyelectrolyte effect is almost invariant with respect to salt concentration but depends on the grafting density of the brush. This invariance is due to a complex cancellation of multiple effects. Based on our results, we show how the experimentally determined p$K_\mathrm{A}$ shifts may be used to infer the grafting density of brushes, a parameter that is difficult to measure directly.

description: Recently, model systems with quadratic Hamiltonians and time-dependent interactions were studied by Briegel and Popescu and by Galve et al. in order to consider the possibility of both quantum refrigeration in enzymes [Proc. R. Soc. 469 20110290 (2013)] and entanglement in the high temperature limit [Phys. Rev. Lett. 105 180501 (2010); Phys. Rev. A 81 062117 (2010)]. Following this line of research, we studied a model comprising two quantum harmonic oscillators driven by a time-dependent harmonic coupling. Such a system was embedded in a thermal bath represented in two different ways. In one case, the bath was composed of a finite but great number of independent harmonic oscillators with an Ohmic spectral density. In the other case, the bath was more efficiently defined in terms of a single oscillator coupled to a non-Hamiltonian thermostat. In both cases, we simulated the effect of the thermal disorder on the generation of the squeezed states in the two-oscillators relevant system. We found that, in our model, the thermal disorder of the bath determines the presence of a threshold temperature, for the generation of squeezed states, equal to T=311.13 K. Such a threshold is estimated to be within temperatures where chemical reactions and biological activity comfortably take place.

description: Over the last few years, many studies have found an empirical relationship between the abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 red-giant stars observed by the APOGEE survey with a median statistical uncertainty of 17%. To this end, we use the supervised machine learning technique XGBoost, trained on a high-quality dataset of 3060 red-giant and red-clump stars with asteroseismic ages observed by both APOGEE and Kepler. After verifying the obtained age estimates with independent catalogues, we investigate some of the classical chemical, positional, and kinematic relationships of the stars as a function of their age. We find a very clear imprint of the outer-disc flare in the age maps and confirm the recently found split in the local age-metallicity relation. We present new and precise measurements of the Galactic radial metallicity gradient in small age bins between 0.5 and 12 Gyr, confirming a steeper metallicity gradient for $\sim2-5$ Gyr old populations and a subsequent flattening for older populations mostly produced by radial migration. In addition, we analyse the dispersion about the abundance gradient as a function of age. We find a clear power-law trend (with an exponent $β\approx0.15$) for this relation, indicating a relatively smooth radial migration history in the Galactic disc over the past $7-9$ Gyr. Departures from this power law may possibly be related to the Gaia Enceladus merger and passages of the Sagittarius dSph galaxy. Finally, we confirm previous measurements showing a steepening in the age-velocity dispersion relation at around $\sim9$ Gyr, but now extending it over a large extent of the Galactic disc (5 kpc $

description: Observations of early-type dwarf galaxies in clusters often show that cluster dwarf members have significantly higher velocities and less symmetric distributions than cluster giant ellipticals, suggesting that these dwarfs are recently accreted galaxies, possibly from an infalling group. We use a series of $N$-body simulations, exploring a parameter space of groups falling into clusters, to study the observed velocity distributions of the infall components along various lines of sight. We show that, as viewed along a line of sight parallel to the group's infall direction, there is a significant peculiar velocity boost during the pericentric passage of the group, and an increase in velocity dispersion that persists for many Gyr after the merger. The remnants of the infalling group, however, do not form a spatially distinct system -- consistent with recent observations of dwarf galaxies in the Virgo and Fornax clusters. This velocity signature is completely absent when viewed along a direction perpendicular to the merger. Additionally, the phase-space distribution of radial velocity along the infall direction versus cluster-centric radius reveals the separate dynamical evolution of the group's central core and outer halo, including the presence of infalling remnants outside the escape velocity envelope of the system. The distinct signature in velocity space of an infalling group's galaxies can therefore prove important in understanding the dynamical history of clusters and their dwarfs. Our results suggest that dwarf galaxies, being insensitive to dynamical friction, are excellent probes of their host clusters' dynamical histories.

The effect of light intensity, temperature, and oxygen pressure on the photo-oxidation rate of bare PbS quantum dots

description: The oxidation speed of PbS quantum dots has been a subject of controversy for some time. In this study, we reveal the precise functional form of the oxidation rate constant for bare quantum dots through analysis of their photoluminescence as a function of temperature, oxygen pressure, and excitation-laser intensity. The combined effect of these factors results in a reduced energy barrier that allows the oxidation to proceed at a high rate. Each absorbed photon is found to have a 10−8 probability of oxidizing a PbS atomic pair. This highlights the importance of photo-excitation on the speed of the oxidation process, even at low illumination conditions. The procedure used here may set up a quantitative standard useful for characterizing the stability of quantum dots coated with ligands/linkers, and to compare different protection schemes in a fair quantitative way.

description: Background: Relapses of granulomatosis with polyangiitis and microscopic polyangiitis, collectively ANCA-associated vasculitis (AAV), are common and important events. Few large, international studies describe risk factors for relapse of AAV. Methods: Relapses occurring in participants with severe AAV enrolled in PEXIVAS, an international, 2-by-2 factorial trial of induction treatments, were studied. The primary outcome of this analysis was relapse occurring at least 90 days after randomization. Candidate predictors included baseline participant and disease characteristics. The association between relapse and the candidate predictors was assessed using time-to-event models incorporating death as a competing event using the Fine and Gray method. All models were adjusted for induction therapies. Results: Over a median follow-up of 2.93 years, 150 (23.3%) participants experienced at least one relapse (incidence rate 7.4 per 100 patient-years). The median time to relapse was 483.5 days (interquartile range 198-920). The most common manifestations of disease at relapse were renal (58.0%), constitutional (38.7%), and ear/nose/throat (31.3%). Baseline characteristics associated with an increased risk of relapse included: PR3-positive ANCA, skin involvement, and non-hemorrhagic lung involvement (Table 1). Characteristics associated with a lower risk of relapse included female sex and receipt of dialysis. Discussion: Relapses remain common among patients with severe AAV. Identifying those most at risk of relapses may help plan treatments and monitoring.

description: Cauchy horizons are well known to exhibit instabilities in classical spacetime dynamics and singularities in quantum field theory. We analyse the response of an Unruh-DeWitt particle detector that falls towards a Cauchy horizon, in terms of the specifics of the horizon, the choice of the quantum state and the specifics of the detector's trajectory. As a prototype, we study in detail the case for the $1+1$ Reissner-Nordström black hole with a scalar field in the Hartle-Hawking state. Comparisons are made with the response of a detector that falls into a Schwarzschild-like singularity.

description: We present a versatile open-source pipeline for simulating inhomogeneous reaction-diffusion processes in highly resolved, image-based geometries of porous media with reactive boundaries. Resolving realistic pore-scale geometries in numerical models is challenging and computationally demanding, as the scale differences between the sizes of the interstitia and the whole system can lead to prohibitive memory requirements. The present pipeline combines a level-set method with geometry-adapted sparse block grids on GPUs to efficiently simulate reaction-diffusion processes in image-based geometries. We showcase the method by applying it to fertilizer diffusion in soil, heat transfer in porous ceramics, and determining effective diffusion coefficients and tortuosity. The present approach enables solving reaction-diffusion partial differential equations in real-world geometries applicable to porous media across fields such as engineering, environmental science, and biology.

description: Purpose: In some proton therapy facilities, patient alignment relies on two 2D orthogonal kV images, taken at fixed, oblique angles, as no 3D on-the-bed imaging is available. The visibility of the tumor in kV images is limited since the patient's 3D anatomy is projected onto a 2D plane, especially when the tumor is behind high-density structures such as bones. This can lead to large patient setup errors. A solution is to reconstruct the 3D CT image from the kV images obtained at the treatment isocenter in the treatment position. Methods: An asymmetric autoencoder-like network built with vision-transformer blocks was developed. The data was collected from 1 head and neck patient: 2 orthogonal kV images (1024x1024 voxels), 1 3D CT with padding (512x512x512) acquired from the in-room CT-on-rails before kVs were taken and 2 digitally-reconstructed-radiograph (DRR) images (512x512) based on the CT. We resampled kV images every 8 voxels and DRR and CT every 4 voxels, thus formed a dataset consisting of 262,144 samples, in which the images have a dimension of 128 for each direction. In training, both kV and DRR images were utilized, and the encoder was encouraged to learn the jointed feature map from both kV and DRR images. In testing, only independent kV images were used. The full-size synthetic CT (sCT) was achieved by concatenating the sCTs generated by the model according to their spatial information. The image quality of the synthetic CT (sCT) was evaluated using mean absolute error (MAE) and per-voxel-absolute-CT-number-difference volume histogram (CDVH). Results: The model achieved a speed of 2.1s and a MAE of <40HU. The CDVH showed that <5% of the voxels had a per-voxel-absolute-CT-number-difference larger than 185 HU. Conclusion: A patient-specific vision-transformer-based network was developed and shown to be accurate and efficient to reconstruct 3D CT images from kV images.

description: We propose a framework combining detrended fluctuation analysis with standard regression methodology. The method is built on detrended variances and covariances and it is designed to estimate regression parameters at different scales and under potential non-stationarity and power-law correlations. The former feature allows for distinguishing between effects for a pair of variables from different temporal perspectives. The latter ones make the method a significant improvement over the standard least squares estimation. Theoretical claims are supported by Monte Carlo simulations. The method is then applied on selected examples from physics, finance, environmental science and epidemiology. For most of the studied cases, the relationship between variables of interest varies strongly across scales.

description: Background/objectives: Patients with AAV are known to have an increased risk for the development of malignancies, which has been largely attributed to immunodeficiency or side effects induced by immunosuppressive treatments. Because there is a considerable latency period for cancer development after exposure to immunosuppressive treatments, little data are available on the incidence of cancer for large cohort of patients with AAV and long follow-up. The aim of this study is to describe the cumulative incidence of cancer in patients with AAV who participated in the EUVAS therapeutic clinical trials from 1995 to 2012. Methods: 848 patients with AAV from 17 European countries were included in the present study. Information was retrieved from questionnaires sent to the principal investigators of the original RCTs (MEPEX, NORAM, CYCAZAREM, CYCLOPS, IMPROVE, RITUXVAS and MYCYC). Results: Among the total of 848 patients (median follow-up: 8 years, IQR: 2.2–8.8), 149 patients were diagnosed with 181 malignancies. The 10-year cumulative incidence of cancer was estimated at 20.6%. The median duration of start of AAV therapy-to-time of cancer diagnosis was 4.96 years (IQR: 2.24-8.83). The most common cancer types were skin cancer (37.4%), out of which 6 were melanoma and 62 non-melanoma skin cancer, followed by gastrointestinal cancer (12.6%) and prostatic cancer (9.9%). Patients who developed cancer were significantly older at randomization than those who did not (62±12 vs 57±14 years) (p<0.001). Considering both remission-induction and remission-maintenance therapies, 94% of the patients received cyclophosphamide, 68.4% azathioprine, 28.2% mycophenolate, 11.4% methotrexate and 10.4% rituximab during the observation period. Six out of the 28 patients, who were treated with rituximab and two pulses of IV cyclophosphamide as induction therapy, developed cancer. Diagnosis of cancer significantly predicted shorter survival (Log rank=9.2, p=0.002). Conclusions: Our findings, which were derived from a large number of patients with AAV enrolled in clinical trials over the past 25 years, estimates the 10-year cumulative incidence of malignancies following the start of AAV therapy at 20.6%. The development of cancer is tightly associated with decreased survival. Analyses of standardized incidence ratios, using the cancer incidence of the background populations as reference, are underway. Disclosures: None

description: The likely presence of $Λ$ baryons in dense hadronic matter tends to soften the equation of state to an extend that the observed heaviest neutron stars are difficult to explain. We analyze this "hyperon problem" with a phenomenological approach. First, we review what can be learned about the interaction of $Λ$ particle with dense matter from the observed hypernuclei and extend this phenomenological analysis to asymmetric matter. We add to this the current knowledge on non-strange dense matter, including its uncertainties, to conclude that the interaction between $Λ$s and dense matter has to become repulsive at densities below three times the nuclear saturation density.

Two-dimensional extended Hubbard model: doping, next-nearest neighbor hopping and phase diagrams

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

description: Using the strong coupling diagram technique, we investigate the extended Hubbard model on a two-dimensional square lattice. This approach allows for charge and spin fluctuations and a short-range antiferromagnetic order at nonzero temperatures. The model features the first-order phase transition to states with alternating site occupations (SAO) at the intersite repulsion $v=v_c$. In this work, we show that doping decreases $v_c$. For a nonzero next-nearest neighbor hopping $t'$, less mobile carriers produce a stronger fall in $v_c$. For half-filling and $t'=0$, we consider phase diagrams for a fixed temperature $T$, on-site $U$, and intersite repulsions. The diagrams contain regions of SAO, Mott insulator, and several metallic states distinguished by their densities of states. Two of them are characterized by a dip and a peak at the Fermi level. The dip originates from the Slater mechanism for itinerant electrons, while the peak to bound states of electrons with localized magnetic moments. The existence of these two metallic regions in the phase diagram is a manifestation of the Pomeranchuk effect. The boundary between these regions reveals itself as a kink in the curve $v_c(T)$ and as a maximum in the $T$ dependence of the double occupancy $D$. Our calculated $D$ for different values of $v$, $U$, and $T$ are in semiquantitative agreement with Monte Carlo results.

description: Indium tin oxide (ITO) is the premier choice for transparent conductive electrodes in optoelectronic devices despite its inherent brittleness. Here we report the fabrication of a grating-like structure that obviates ITO's mechanical limitations while retaining its resistivity and optical qualities. ITO nanopatterned films exhibited a resistivity <1.3 × 10-3 Ω cm, which surpassed all previously reported values for flexible ITO, with a normal transmission >90% across the whole visible spectrum range. We demonstrate the nanopatterned ITO retains extraordinary flexibility and durability on heat-sensitive substrates, accommodating cyclic bending to a curvature diameter of at least 3.2 mm for over 50 cycles of compressive and decompressive flexing without significant deterioration of its resistivity or optical properties. Moreover, 2-dimensional extrapolation shows that multiaxial bending is also feasible while maintaining mechanical flexibility, durability, and optical transparency.
Slippery and mobile hydrophobic electrokinetics: from single walls to nanochannels

description: We discuss how the wettability of solid walls impacts electrokinetic properties, from large systems to a nanoscale. We show in particular how could the hydrophobic slippage, coupled to confinement effects, be exploited to induce novel electrokinetic properties, such as a salt-dependent giant amplification of zeta potential and conductivity, and a much more efficient energy conversion. However, the impact of slippage is dramatically reduced if some surface charges migrate along the hydrophobic wall under an applied field.

description: In this paper we derive some new invariant solutions of Einstein-Maxwell's field equations for string fluid as source of matter in cylindrically symmetric space-time with Variable Magnetic Permeability. We also discuss the physical and eometrical properties of the models derived in the paper. The solutions, at least one of them, are interesting physically as they can explain the accelerating as well as singularity free Universe.

description: Background/ Objectives: Glucocorticoids (GCs) are the mainstay treatment for Takayasu’s arteritis (TAK). However, GC-related toxicity still remains a major concern. In this study we aimed to evaluate GC-associated damage in TAK patients with glucocorticoid toxicity index (GTI) which was developed to assess GC-related toxicity. Methods: Patients followed in Marmara University Hospital Vasculitis Clinic with a diagnosis of TAK and receiving GC treatment were enrolled in the study. Damage was assessed with GTI under the headings: body mass index (BMI), glucose tolerance, blood pressure, lipids, bone density, steroid myopathy, skin toxicity, neuropsychiatric toxicity, infection, endocrine, gastrointestinal, musculoskeletal, ocular domains. Total GTI score range was defined between −36 and 439.
 Results: A total of 57 (F/M: 53/4) TAK patients were included. Mean age was 44.3±12.5 years and cumulative GC dose 11.1±7.2 grams. After mean 82.8±53.8 months of GC treatment, mean GTI score was found to be 51.5±52.4. GTI score was similar between genders (Total GTI: women vs men: 50.2±52.0 vs 37.2±11.7, p=0.88). Total GTI score correlated with age (r=0.32, p=0.014), cumulative GC dose (r=0.34, p=0.017) and duration of GC treatment (r=0.27, p=0.041). Conclusions: GC-related toxicity was related to cumulative dose and duration of the GC treatment in our study. GTI is a useful tool to evaluate GC-related toxicity and can be chosen both for clinical studies and routine practice to assess long-term GC-associated damage. Disclosures: None

description: We present a temperature extrapolation technique for self-consistent many-body methods, which provides a causal starting point for converging to a solution at a target temperature. The technique employs the Carathéodory formalism for interpolating causal matrix-valued functions and is applicable to various many-body methods, including dynamical mean field theory, its cluster extensions, and self-consistent perturbative methods such as the self-consistent GW approximation. We show results that demonstrate that this technique can efficiently simulate heating and cooling hysteresis at a first-order phase transition, as well as accelerate convergence.

Авторы анализируют специфику и подходы к изучению чайлдфри, последствия распространения чалдфри для демографического будущего России. Авторы делают выводы, что, несмотря на сильную привязанность к традиционным ценностям, данный вид семейного поведения складывается в самостоятельную практику и отношение в обществе к нему все более толерантно. Данная проблема требует разработки социальных технологий и мер государственной поддержки для сохранения и поддержания традиционных ценностей семьи и брака.
description: The article is devoted to childfree and the factors of its spread. The authors analyze the specifics and approaches to the study of childfree, the consequences of the spread of childfree for the demographic future of Russia. The authors conclude that, despite the strong attachment to traditional values, this type of family behavior develops into an independent practice and the attitude in society towards it is increasingly tolerant. This problem requires the development of social technologies to preserve and maintain traditional values.
