description: The circular Dyson Brownian motion model refers to the stochastic dynamics of the log-gas on a circle. It also specifies the eigenvalues of certain parameter-dependent ensembles of unitary random matrices. This model is considered with the initial condition that the particles are non-interacting (Poisson statistics). Jack polynomial theory is used to derive a simple exact expression for the density-density correlation with the position of one particle specified in the initial state, and the position of one particle specified at time $τ$, valid for all $β> 0$. The same correlation with two particles specified in the initial state is also derived exactly, and some special cases of the theoretical correlations are illustrated by comparison with the empirical correlations calculated from the eigenvalues of certain parameter-dependent Gaussian random matrices. Application to fluctuation formulas for time displaced linear statistics in made.

Zabaluev (IZCS); 4 larvae and 1 pupa, 18.05.2021, Russia, Saratov region, near Sinenkiye vill. (51.244222°N 45.745267°E), ex buds of M. domestica, leg. and det. I.A. Zabaluev (IZCS).
 Measurements of larvae (in mm). Body length: 3.78–4.78 (mean 4.25). Body width: 1.58–1.79 (mean 1.70). Head width: 0.69–0.71 (mean 0.70).
 Measurements of pupae (in mm). Body length: 3.73–4.96 (mean 4.09). Body width: 1.44–1.78 (mean 1.59). Head width: 0.53–0.60 (mean 0.55). Rostrum 3.6–4.2x as long as wide in male, and 4.2–4.5x in female. Pronotum 1.4–1.5x as wide as long.
 Remarks. The larva (Ahmad & Burke 1972) and pupa (Burke 1968) of this species have already been described. The material studied by me corresponds well to these descriptions, except that this species has three pairs of ligular setae (ligs) (= glossal), rather than two, as indicated in the previous description. Also, when describing the antenna, not all sensilla were indicated. Basal membranous segment (Figs. 105) with conical sensorium (se) and five sensilla: one ampullacea (sa), three styloconium (ss) and one basiconicum (sb). The pupa of this species has ventral setae (v) on the abdominal segments, as in A. incurvus, but in most specimens these setae are usually visible only on I–IV segments.

description: Planet migration in protoplanetary discs plays an important role in the longer term evolution of planetary systems, yet we currently have no direct observational test to determine if a planet is migrating in its gaseous disc. We explore the formation and evolution of dust rings - now commonly observed in protoplanetary discs by ALMA - in the presence of relatively low mass (12-60 Earth masses) migrating planets. Through two dimensional hydrodynamical simulations using gas and dust we find that the importance of perturbations in the pressure profile interior and exterior to the planet varies for different particle sizes. For small sizes a dust enhancement occurs interior to the planet, whereas it is exterior to it for large particles. The transition between these two behaviours happens when the dust drift velocity is comparable to the planet migration velocity. We predict that an observational signature of a migrating planet consists of a significant outwards shift of an observed midplane dust ring as the wavelength is increased.

Chapter 11 - Heterogeneous photo-Fenton reaction and its enhancement upon addition of chelating agents

name: Dutta, Joydeep
Publisher: name: Zenodo
Year: 2020

description: Abstract Water pollution caused by recalcitrant organic molecules from industrial and domestic sectors has become a major problem that can affect human health and the balance of our ecosystem. Fenton oxidation process based on the generation of highly reactive hydroxyl radicals (⋅OH) is one of the most efficient methods to overcome this issue. However, this process has three significant limitations such as the narrow working pH range, the formation of iron sludge, and the nonreuse of iron catalyst. To overcome these shortcomings, the use of heterogeneous photo-Fenton process is widely recommended. This chapter reviews the main advances in heterogeneous photo-Fenton oxidation and especially the use of chelating agents such as nitrilotriacetic acid, ethylenediamine-N,N′-disuccinic acid, and oxalate C2O42− as a promising solution to enhance the degradation efficiency of refractory organic pollutants.

description: Although attention bias (AB) toward threat has been associated with Social Anxiety Disorder (SAD), concerns regarding the ability of current measures to detect change in AB following treatment exist. We sought to examine change in bias, as measured via eye-tracking, in adolescents with SAD receiving either attention-bias modification training (ABMT) or attention-control training (ACT). Gaze-based AB was associated (r = −0.361) with symptoms of social anxiety prior to treatment, whereas there was no association between bias as measured via dot probe and social anxiety. Moreover, gaze-based bias to same-age face stimuli showed change following treatment. Large effects are seen for condition (ABMT or ACT) and for time, independent of treatment condition, in gaze-based AB to same-age stimuli. Findings suggest that further research on gaze-based bias, to assess stability over time outside of treatment and sensitivity to change following intervention, is warranted.

description: We present the timing parameters of nine pulsars discovered in a survey of intermediate Galactic latitudes at 1400 MHz with the Parkes radio telescope. Eight of these pulsars possess small pulse periods and period derivatives thought to be indicative of ``recycling''. Six of the pulsars are in circular binary systems, including two with relatively massive white dwarf companions. We discuss the implications of these new systems for theories of binary formation and evolution. One long-period pulsar (J1410-7404) has a moderately weak magnetic field and an exceedingly narrow average pulse profile, similar to other recycled pulsars.

Contact transience during slow loading of dense granular materials

description: The irregularity of particle motions during quasi-static deformation is investigated using discrete element (DEM) simulations of sphere and sphere-cluster assemblies. A total of three types of interparticle movements are analyzed: relative motions of particle centers, relative motions of material points of two particles at their contact, and the traversal of contacts across the surfaces of particles. Motions are a complex combination of rolling, sliding, and elastic distortion at the contacts, and all motions are highly irregular and variant, qualities that increase with increasing strain. The relative motions of particle centers diverge greatly from those of an affine displacement of the particles. The motions of the nonconvex sphere-cluster particles were more regular that those of the spheres. The paper also investigates the effect of the distance between two remote particles and their pair-wise relative displacements. Even for particle pairs separated by more than six intermediate particles, the relative motions do not conform with the mean deformation (affine) field. Force chains are shown to be transient features, which survive only briefly across elapsed strains.

description: Distraction can reduce adults’ memory for emotion-eliciting information, whereas reappraisal can preserve or enhance it. Yet, when given instructions to use specific emotion regulation (ER) strategies, adults report using other strategies too. The consequences of non-instructed strategy use within instructed ER paradigms are rarely examined. We investigated how both instructed and non-instructed but reported strategies related to memory for emotional information in childhood. Older (N = 69; 8- to 10-year-olds; 24 girls) and younger (N = 65; 5- to 7-year-olds; 35 girls) children received instructions to use cognitive distraction, reappraisal, or do nothing (control) before and after viewing a negative emotional film clip. Children were later interviewed about what they remembered about the film, and reported the ER strategies they used during it. Memory did not vary across instructed ER strategy conditions, and reported strategies did not relate to memory differently for older and younger children. Consistent with adult work, reported cognitive distraction related to poorer memory. Different reappraisal types were reported, but only situation-focused reappraisal was linked to better memory. In sum, children’s reported cognitive distraction and reappraisal strategies related to memory for emotional information differently. Thus, ER strategies divergently relate to what children remember about their emotional experiences.

description: Various company interactions can be described by networks, for instance the ownership networks and the board membership networks. To understand the ecosystem of companies, these interactions cannot be seen in isolation. For this purpose we construct a new multilayer network of interactions between companies in Germany and in the United Kingdom, combining ownership links, social ties through joint board directors, R\&D collaborations and stock correlations in one linked multiplex dataset. We describe the features of this network and show there exists a non-trivial overlap between these different types of networks, where the different types of connections complement each other and make the overall structure more complex. This highlights that corporate control, boardroom influence and other connections have different structures and together make an even smaller corporate world than previously reported. We have a first look at the relation between company performance and location in the network structure.

Reaction Kinetics in Polymer Melts

description: We study the reaction kinetics of end-functionalized polymer chains dispersed in an unreactive polymer melt. Starting from an infinite hierarchy of coupled equations for many-chain correlation functions, a closed equation is derived for the 2nd order rate constant $k$ after postulating simple physical bounds. Our results generalize previous 2-chain treatments (valid in dilute reactants limit) by Doi, de Gennes, and Friedman and O'Shaughnessy, to arbitrary initial reactive group density $n_0$ and local chemical reactivity $Q$. Simple mean field (MF) kinetics apply at short times, $k \sim Q$. For high $Q$, a transition occurs to diffusion-controlled (DC) kinetics with $k \approx x_t^3/t$ (where $x_t$ is rms monomer displacement in time $t$) leading to a density decay $n_t \approx n_0 - n_0^2 x_t^3$. If $n_0$ exceeds the chain overlap threshold, this behavior is followed by a regime where $n_t \approx 1/x_t^3$ during which $k$ has the same power law dependence in time, $k \approx x_t^3/t$, but possibly different numerical coefficient. For unentangled melts this gives $n_t \sim t^{-3/4}$ while for entangled cases one or more of the successive regimes $n_t \sim t^{-3/4}$, $t^{-3/8}$ and $t^{-3/4}$ may be realized depending on the magnitudes of $Q$ and $n_0$. Kinetics at times longer than the longest polymer relaxation time $τ$ are always MF. If a DC regime has developed before $τ$ then the long time rate constant is $k \approx R^3/τ$ where $R$ is the coil radius. We propose measuring the above kinetics in a model experiment where radical end groups are generated by photolysis.

description: We study cutoff and lattice effects in the O(n) symmetric $ϕ^4$ theory for a $d$-dimensional cubic geometry of size $L$ with periodic boundary conditions. In the large-N limit above $T_c$, we show that $ϕ^4$ field theory at finite cutoff $Λ$ predicts the nonuniversal deviation $\sim (ΛL)^{-2}$ from asymptotic bulk critical behavior that violates finite-size scaling and disagrees with the deviation $\sim e^{-cL}$ that we find in the $ϕ^4$ lattice model. The exponential size dependence requires a non-perturbative treatment of the $ϕ^4$ model. Our arguments indicate that these results should be valid for general $n$ and $d > 2$.

description: Abstract

This research paper explores the challenges and opportunities in managing electronic waste (E-waste) in India through the lens of a circular economy approach. E-waste poses significant environmental and health risks due to its complex composition of valuable and hazardous materials. The linear consumption model prevalent in many countries, including India, exacerbates the E-waste problem by promoting a "take-make-dispose" paradigm. However, transitioning to a circular economy model offers a promising solution by emphasizing resource efficiency, product reuse, and material recycling. Through a comprehensive analysis of current E-waste management practices, legislative frameworks, and ongoing initiatives in India, this paper identifies key strategies for improving E-waste management within a circular economy framework. These strategies include enhancing reverse logistics systems, promoting the 3Rs (Reduce, Reuse, Recycle) principles, integrating informal recycling sectors, raising public awareness, and implementing digital tracking mechanisms. By adopting these strategies and leveraging the principles of the circular economy, India can mitigate the environmental impact of E-waste, conserve valuable resources, and foster sustainable development.

description: Here, we report on the detection and verification of Fast Radio Burst FRB 180301, which occurred on UTC 2018 March 1 during the Breakthrough Listen observations with the Parkes telescope. Full-polarization voltage data of the detection were captured--a first for non-repeating FRBs--allowing for coherent de-dispersion and additional verification tests. The coherently de-dispersed dynamic spectrum of FRB 180301 shows complex, polarized frequency structure over a small fractional bandwidth. As FRB 180301 was detected close to the geosynchronous satellite band during a time of known 1-2 GHz satellite transmissions, we consider whether the burst was due to radio interference emitted or reflected from an orbiting object. Based on the preponderance of our verification tests, we find that FRB 180301 is likely of astrophysical origin, but caution that anthropogenic sources cannot conclusively be ruled out.

description: Spacetime-constrained oblivious transfer (SCOT) extends the fundamental primitive of oblivious transfer to Minkowski space. SCOT and location oblivious data transfer (LODT) are the only known cryptographic tasks with classical inputs and outputs for which unconditional security needs both quantum theory and relativity. We give an unconditionally secure SCOT protocol that, contrasting previous SCOT and LODT protocols, is practical to implement with current technology, where distant agents need only communicate classical information, while quantum communication occurs at a single location. We also show that our SCOT protocol can be used to implement unconditionally secure quantum relativistic bit commitment.

description: During their formation and early evolution, rocky planets undergo multiple global melting events due to accretionary collisions with other protoplanets. The detection and characterization of their post-collision afterglows (magma oceans) can yield important clues about the origin and evolution of the solar and extrasolar planet population. Here, we quantitatively assess the observational prospects to detect the radiative signature of forming planets covered by such collision-induced magma oceans in nearby young stellar associations with future direct imaging facilities. We have compared performance estimates for near- and mid-infrared instruments to be installed at ESO's Extremely Large Telescope (ELT), and a potential space-based mission called Large Interferometer for Exoplanets (LIFE). We modelled the frequency and timing of energetic collisions using \textit{N}-body models of planet formation for different stellar types, and determine the cooling of the resulting magma oceans with an insulating atmosphere. We find that the probability of detecting at least one magma ocean planet depends on the observing duration and the distribution of atmospheric properties among rocky protoplanets. However, the prospects for detection significantly increase for young and close stellar targets, which show the highest frequencies of giant impacts. For intensive reconnaissance with a K band (2.2 $μm$) ELT filter or a 5.6 $μm$ LIFE filter, the $β$ Pictoris, Columba, TW Hydrae, and Tucana-Horologium associations represent promising candidates for detecting a molten protoplanet. Our results motivate the exploration of magma ocean planets using the ELT and underline the importance of space-based direct imaging facilities to investigate and characterize planet formation and evolution in the solar vicinity.

description: The Difference Image Analysis (DIA) of the images obtained by the Optical Gravitational Lensing Experiment (OGLE-II) revealed a peculiar artifact in the sample of stars proposed as variable by Wozniak (2000) in one of the Galactic bulge fields: the occurrence of pairs of candidate variables showing anti-correlated light curves monotonic over a period of 3 years. This effect can be understood, quantified and related to the stellar proper motions. DIA photometry supplemented with a simple model offers an effective and easy way to detect high proper motion stars (HPM stars) in very dense stellar fields, where conventional astrometric searches are extremely inefficient.

The survey of the CMB over $\mathbb{S}^2$ is incomplete due to obfuscation effects by bright point sources and other extended foreground objects like our own galaxy. To deal with such situations, where analysis in the presence of "masks" is of importance, we introduce the concept of relative homology. The parametric $χ^2$-test shows differences between observations and simulations, yielding $p$-values at per-cent to less than per-mil levels roughly between 2 to 7 degrees. The highest observed deviation for $b_0$ and $b_1$ is approximately between $3σ$-4$σ$ at scales of 3 to 7 degrees. There are reports of mildly unusual behaviour of the Euler characteristic at 3.66 degrees in the literature, computed from independent measurements of the CMB temperature fluctuations by Planck's predecessor WMAP satellite. The mildly anomalous behaviour of Euler characteristic is related to the strongly anomalous behaviour of components and holes. These are also the scales at which the observed maps exhibit low variance compared to the simulations. Non-parametric tests show even stronger differences at almost all scales. Regardless, beyond the trivial possibility that this may still be a manifestation of an extreme Gaussian case, these observations, along with the super-horizon scales involved, may motivate to look at primordial non-Gaussianity. Alternative scenarios worth exploring may be models with non-trivial topology.

description: Different nanomaterials are under development for various biomedical applications in which nanoparticles contact blood and vasculature. Therefore, investigating the interactions between nanomaterials and vascular endothelial cells (ECs) is of great importance. Here, we show the effects of polyamidoamine (PAMAM) dendrimers of two different sizes, generation 2 (G2; approximately 3 nm diameter) and generation 7 (G7; 9 nm), with neutral (OH-terminated), anionic (COOH-terminated), and cationic (NH2-terminated) surface modifications on cultured human umbilical vein ECs (HUVECs). We found that only cationic dendrimers (5–100 μg/mL G7-NH2 and 100 µg/mL G2-NH2) and not anionic or neutral dendrimers were cytotoxic to HUVECs. In addition, cationic dendrimers at low concentrations (5 μg/mL) markedly increased the HUVEC surface expression of the proinflammatory activation marker ICAM-1 and phosphatidylserine (PS). Both G2-NH2 and G7-NH2 dendrimers caused g1 arrest, but only G7-NH2 dendrimers induced significant HUVEC apoptosis. G7-NH2 interacted strongly with HUVEC plasma membranes and mitochondrial membranes, and phospholipid vesicles containing G7-NH2 formed, which resulted in extensive plasma membrane blebbing and disintegration. Furthermore, flow cytometric analysis showed that G7-NH2-treated HUVECs released large numbers of extracellular vesicles (EVs) positive for CD105 and PS. A notable population of EVs positive for the mitochondrial marker TOM20 but negative for the autophagosome marker LC3 was found. In summary, large cationic PAMAM dendrimers (G7-NH2) showed both proinflammatory and proapoptotic effects in ECs; at high dendrimer concentrations, these effects were accompanied by necrotic cytotoxicity. G7-NH2 caused plasma and mitochondrial membrane disintegration and the release of EVs, including EVs of mitochondrial origin that were not associated with mitophagy.

description: The critical filling factor v_c where Shubnikov-de Haas oscillations become spin split is investigated for a set of GaAs-GaAlAs heterojunctions. Finite temperature magnetoresistance measurements are used to extract the value of v_c at zero temperature. The critically point is where the disorder potential has the same magnitude as the exchange energy, leading to the empirical relationship v_c = g* n t h / 2 m_0. This is valid for all the samples studied, where the density n and single particle lifetime t both vary by more than an order of magnitude and g* the exchange enhanced g-factor has a weak dependence on density. For each sample the spin gap energy shows a linear increase with magnetic field. Experiments in tilted magnetic field show the spin gap is the sum of the bare Zeeman energy and an exchange term. This explains why measurements of the enhanced g-factor from activation energy studies in perpendicular field and the coincidence method in tilted fields have previously disagreed.

description: Site energy of the five-state ferromagnetic Potts model is numerically calculated at the first-order transition temperature using corner transfer matrix renormalization group (CTMRG) method. The calculated energy of the disordered phase $U^{+}$ is clearly different from that of the ordered phase $U^{-}$. The obtained latent heat $L = U^{-} - U^{+}$ is 0.027, which quantitatively agrees with the exact solution.

description: We compare the rise and decay timescales of $\sim$200 long-term ($\sim$weeks-months) GeV and R-band outbursts and $\sim$25 short-term ($\sim$hr-day) GeV flares in a sample of 10 blazars using light curves from the Fermi-LAT and the Yale/SMARTS monitoring project. We find that most of the long-term outbursts are symmetric, indicating that the observed variability is dominated by the crossing timescale of a disturbance, e.g., a shock. A larger fraction of short-term flares are asymmetric with an approximately equal fraction of longer and shorter decay than rise timescale. We employ the MUlti-ZOne Radiation Feedback (MUZORF) model to interpret the above results. We find that the outbursts with slow rise times indicate a gradual acceleration of the particles to GeV energy. A change in the bulk Lorentz factor of the plasma or the width of the shocked region can lead to an increase of the cooling time causing a faster rise than decay time. Parameters such as the luminosity or the distance of the broad line region (BLR) affects the cooling time strongly if a single emission mechanism, e.g., external Compton scattering of BLR photons is considered but may not if other mechanisms, e.g., synchrotron self-compton and external Compton scattering of the torus photon are included. This work carries out a systematic study of the symmetry of flares, which can be used to estimate relevant geometric and physical parameters of blazar jets in the context of the MUZORF model.

Violation of Finite-Size Scaling in Three Dimensions

description: We reexamine the range of validity of finite-size scaling in the $ϕ^4$ lattice model and the $ϕ^4$ field theory below four dimensions. We show that general renormalization-group arguments based on the renormalizability of the $ϕ^4$ theory do not rule out the possibility of a violation of finite-size scaling due to a finite lattice constant and a finite cutoff. For a confined geometry of linear size $L$ with periodic boundary conditions we analyze the approach towards bulk critical behavior as $L \to \infty$ at fixed $ξ$ for $T > T_c$ where $ξ$ is the bulk correlation length. We show that for this analysis ordinary renormalized perturbation theory is sufficient. On the basis of one-loop results and of exact results in the spherical limit we find that finite-size scaling is violated for both the $ϕ^4$ lattice model and the $ϕ^4$ field theory in the region $L \gg ξ$. The non-scaling effects in the field theory and in the lattice model differ significantly from each other.

description: The nature of superluminal photon propagation in the gravitational field describing radiation from a time-dependent, isolated source (the Bondi-Sachs metric) is considered in an effective theory which includes interactions which violate the strong equivalence principle. Such interactions are, for example, generated by vacuum polarisation in conventional QED in curved spacetime. The relation of the resulting light-cone modifications to the Peeling Theorem for the Bondi-Sachs spacetime is explained.

description: Genistein is a widely studied phytoestrogen. The effects of genistein on myoblasts were reported long ago, but the conclusions are controversial. In this study, we evaluated the effects of different concentrations of genistein on C2C12 myoblasts.Genistein treatment promoted myoblast proliferation in a dose-dependent manner in the concentration range of 0–2 µM/L, reaching its maximum effect at 2 µM/L. Proliferation then declined, and a concentration higher than 20 µM/L showed significant inhibition. In addition, genistein treatment promoted myoblast differentiation at a dose of 10 µM/L. However, at treatment concentrations higher than 10 µM/L, the effect on myoblast differentiation was rapidly inhibited as the concentration increased.Genistein treatment also down-regulated the expression of miR-222, resulting in increased expression of its target genes, MyoG, MyoD, and ERα and thereby promoting myoblast differentiation.Our results suggest that genistein has a dose-dependent and bidirectional regulation effect on myoblast proliferation and differentiation. We also found that genistein is a miRNA inducer, and it specifically affects the expression of miR-222 to regulate myoblast differentiation. Genistein is a widely studied phytoestrogen.

description: The diagnosis and treatment of spine disorders have been challenging for thousands of years in different nations and medical schools. Despite this long history, there are many information gaps in this regard. The current research deals with the milestones and progress of spine surgery from ancient times until now, emphasizing the innovations of sages in the Persian traditional medicine era. The present study is based on searching original and library documents, data from databases such as PubMed, Scopus, and Science Direct, and search engines such as Google Scholar. In Persian traditional medicine, Rhazes (865–925 AD) was the first sage who applied spine surgery based on the innovative knowledge of Galen (second century AD) and Paulus Aegineta (seventh century AD). Hally Abbas (tenth century AD), by suturing two separated bones during spine surgery, and Albucasis (936–1013 AD), by inventing, describing, and drawing the surgical instruments involved in surgeries in this area, and also using cauterization in the treatment of children’s hunchback, were the innovators of new methods. The modern knowledge of spine surgery is based on intelligent experiences and prominent thoughts from thousands of years worldwide. However, sometimes, these key points have remained hidden. This issue necessitates investigating this science in different schools and territories for comparative studies, identifying the firsts in the prominent points of this field, preserving the identity of sages and nations, and preventing scientific plagiarism.
Inclusive jet measurements in pp and Pb-Pb collisions with ALICE

description: Measurements of jet yields in heavy-ion collisions can be used to constrain jet energy loss models, and in turn provide information about the physical properties of deconfined QCD matter. ALICE reconstructs charged particle jets ($\textit{charged jets}$) with high-precision tracking of charged particles down to $p_{\mathrm{T}}^{\mathrm{track}} = 150$ MeV/$c$, and jets ($\textit{full jets}$) with the addition of particle information from the electromagnetic calorimeter down to $E_{\mathrm{cluster}} = 300$ MeV. By including low momentum jet constituents, ALICE is uniquely positioned at the LHC to measure jets down to low jet momentum, to determine the modification to the soft components of jets, and to measure medium recoil particles. New inclusive full jet measurements in pp and Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with ALICE will be shown, over $R=0.2-0.4$ and extending to low jet $p_{\mathrm{T}}$. These will include the jet $R_{\mathrm{AA}}$ for different jet $R$, and will constitute the first such full jet measurements at low transverse jet momentum at this collision energy. The results are compared to several theoretical predictions.
