Accretion and emission processes in AGN

description: The UV-X continuum, the X-ray spectral features, and the variability in these bands provide powerful tools for studying the innermost regions of AGNs from which we gain an insight into the accretion process. In this chapter the discussion focusses on luminous AGN, i.e. Seyfert galaxies and quasars. The standard accretion disk model (a stationary geometrically thin disk) is described, and vertically averaged solutions for the radial structure are given. The emission of the standard disk is discussed using different approximations, and it is compared to the observations. This leads to the conclusion that more complex models are required, such as the irradiated disk and the disk-corona models. The advantage of this last model is that it explains the overall UV-X spectral distribution. In the framework of these disk models, the profile, intensity, and variability properties of the X-ray iron line can be explained by reprocessing at the surface of the cold disk very close to the black hole (the "relativistic disk model"). An alternative possibility is discussed, where the UV-X continuum is produced by a quasi-spherical distribution of dense clouds surrounded by (or embedded in) a hot medium. In such a model the iron line profile could be due to Comptonization instead of relativistic effects.

description: Materials with in-plane electrical anisotropy have great potential for designing artificial synaptic devices. However, natural materials with strong intrinsic in-plane electrical anisotropy are rare. We introduce a simple strategy to produce extremely large electrical anisotropy via grating gating of a semiconductor two-dimensional electron gas (2DEG) of AlGaN/GaN. We show that periodically modulated electric potential in the 2DEG induces in-plane electrical anisotropy, which is significantly enhanced in a magnetic field, leading to an ultra large electrical anisotropy. This is induced by a giant positive magnetoresistance and a giant negative magnetoresistance under two orthogonally oriented in-plane current flows, respectively. This giant electrical anisotropy is in-situ tunable by tailoring both the grating gate voltage and the magnetic field. Our semiconductor device with controllable giant electrical anisotropy will stimulate new device applications, such as multi-terminal memtransistors and bionic synapses.

description: We develop a field theory to study the dynamics of long wavelength exchange spin wave excitations on honeycomb nanoribbons characterized by armchair edge boundaries and the Néel antiferromagnetic ordering state. Appropriate boundary conditions are established by requiring that the bulk and edge spins precess with the same frequency for any given spin wave eigenmode in these systems. A set of characteristic boundary equations, common for bulk and edge spin wave modes, are hence derived. The equations of motion for the spin dynamics are then solved to determine the propagating and evanescent exchange spin wave modes. We prove in general that the bulk spin wave dynamics is discretized due to the finite width of the nanoribbon. For an isotropic magnetic nanoribbon, the Dirac cone is reduced to a single linear dispersion curve due to this discretization. The number and wavelengths of allowed bulk modes for isotropic and anisotropic nanoribbons are determined from the derived characteristic boundary equations. As witnessed by our numerical results for different examples it is shown that the characteristics of these modes depend on the width of the nanoribbon and its antiferromagnetic anisotropy. Further, anisotropic nanoribbons, even those with the slightest anisotropy, present evanescent modes with non-linear dispersion relations. The spatial variation of the amplitudes of the evanescent exchange spin waves across the finite widths of the nanoribbons, is found to be strongly dependent on the system magnetic anisotropy and its width. The developed theoretical approach is general and can be applied for nanoribbons with all types of boundary edges.

description: In recent years, the skyrmion lattice phase with a short lattice constant has attracted attention due to its high skyrmion density, making it a promising option for achieving high-density storage memory and for observing novel phenomena like the quantized topological Hall effect. Unlike conventional non-centrosymmetric systems where the Dzyaloshinsky-Moriya interaction plays a crucial role, the short pitch skyrmion phase requires a quadratic magnetic interaction $J(q)$ with a peak at finite-$Q$, and weak easy-axis magnetic anisotropy is also critical. Thus, conducting first-principles evaluations is essential for understanding the formation mechanism as well as for promoting the discovery of new skyrmion materials. In this {\it Perspective}, we focus on recent developments of the first-principles evaluations of these properties and apply them to the prototype systems Gd$T_2X_2$ and Eu$T_2X_2$, where $T$ denotes a transition metal and $X$ represents Si or Ge. In particular, based on the spin density functional theory with the Hubbard correction combined with the Liechtenstein method in the Wannier tight-binding model formalism, we first show that the Hubbard $U$ and Hund's coupling is essential to stabilize a skyrmion lattice state by enhancing the easy-axis anisotropy. We then discuss mechanisms of finite-$Q$ instability and show that competition among Gd-5$d$ orbitals determines whether ferromagnetism or a finite-$Q$ structure is favored in Gd$T_2$Si$_2$ with $T=$ Fe and Ru. Our systematic calculations reveal that GdRu$_2$$X_2$, GdOs$_2$$X_2$, and GdRe$_2X_2$ are promising, while GdAg$_2X_2$, GdAu$_2X_2$, and EuAg$_2X_2$ are possible candidates as the skyrmion host materials. Analysis based on a spin spiral calculation for the candidate materials is also presented.

description: miRNAs are a class of non-coding endogenous small RNAs that control gene expression at the posttranscriptional level and involved in cell proliferation, migration and differentiation. Dysregulation of miRNA expression is involved in a variety of human diseases including cardiovascular diseases. miRNAs have been shown to regulate vascular smooth muscle cell (VSMC) function and play vital roles in hypertension, restenosis and atherosclerosis. Here we reported that miR-16 as one of miRNAs in the miR-15 family was highly expressed in vascular smooth muscle cells (VSMCs) and involved in angiotensin II (Ang II) mediated VSMC signaling pathways. Ang II downregulated miR-16 expression in VSMCs. Lentiviral vector mediated miR-16 knockdown promoted Ang II-induced cell proliferation and migration. Moreover, silencing miR-16 enhanced Ang II induced cell cycle associated gene expression and promoted Ang II-activated cell proliferative pathways ERK1/2 and p38. Our finding demonstrated for the first time that miR-16 was a potential therapeutic target by participating in the Ang II-associated multiple signaling pathways in cardiovascular diseases.

description: We develop a high-throughput computational scheme based on cluster multipole theory to identify new functional antiferromagnets. This approach is applied to 228 magnetic compounds listed in the AtomWork-Adv database, known for their elevated Néel temperatures. We conduct systematic investigations of both stable and metastable magnetic configurations of these materials. Our findings reveal that 34 of these compounds exhibit antiferromagnetic structures with zero propagation vectors and magnetic symmetries identical to conventional ferromagnets, rendering them potentially invaluable for spintronics applications. By cross-referencing our predictions with the existing MAGNDATA database and published literature, we verify the reliability of our findings for 26 out of 28 compounds with partially or fully elucidated magnetic structures in the experiments. These results not only affirm the reliability of our scheme but also point to its potential for broader applicability in the ongoing quest for the discovery of new functional magnets.13

description: We investigate the physical properties of structures seen in channel map observations of 21-cm neutral hydrogen (HI) emission. HI intensity maps display prominent linear structures that are well aligned with the ambient magnetic field in the diffuse interstellar medium (ISM). Some literature hold that these structures are "velocity caustics", fluctuations imprinted by the turbulent velocity field, and are not three-dimensional density structures in the ISM. We test this hypothesis by stacking probes of the density field -- broadband far infrared (FIR) emission and the integrated HI column density (NHI) -- at the locations of linear HI intensity structures. We find that the HI intensity features are real density structures and not velocity caustics. We generalize the investigation to all small-scale structure in HI channel maps, and analyze this correlation as a function of velocity channel width, finding no measurable contribution from velocity caustics to the HI channel map emission. Further, we find that small-scale HI channel maps structures have elevated FIR/NHI, implying that this emission originates from a colder, denser phase of the ISM than the surrounding material. The data are consistent with a multi-phase diffuse ISM in which small-scale structures in narrow HI channel maps are preferentially cold neutral medium (CNM) that is anisotropically distributed and aligned with the local magnetic field. The shallow spatial power spectrum (SPS) of narrow HI channels is often attributed to velocity caustics. We conjecture instead that the small-scale structure and narrow linewidths typical of CNM explain the observed relationship between the SPS and channel width.

description: The understanding of epidemics on networks has greatly benefited from the recent application of message-passing approaches, which allow to derive exact results for irreversible spreading (i.e. diseases with permanent acquired immunity) in locally-tree like topologies. This success has suggested the application of the same approach to reversible epidemics, for which an individual can contract the epidemic and recover repeatedly. The underlying assumption is that backtracking paths (i.e. an individual is reinfected by a neighbor he/she previously infected) do not play a relevant role. In this paper we show that this is not the case for reversible epidemics, since the neglect of backtracking paths leads to a formula for the epidemic threshold that is qualitatively incorrect in the large size limit. Moreover we define a modified reversible dynamics which explicitly forbids direct backtracking events and show that this modification completely upsets the phenomenology.

description: IMPACT HTA Work Package 10 (WP10) is developing guidance on novel approaches to appraising medicines for rare diseases to support robust, accountable decision-making across Europe on high-cost products that have a limited evidence base with high uncertainty and intense stakeholder scrutiny. WP10 is exploring how different forms of evidence obtained from a range of data sources and stakeholders can be integrated with economic modelling to inform robust, accountable decisions about OMPs and ultra-OMPs.
 The first step was to document HTA appraisal/reimbursement processes for medicines for rare diseases in all EU Member States, Canada, New Zealand and Australia in WP10 workstream 1. This information was used to explore whether there is a for need supplemental HTA appraisal processes for rare disease treatments (RDTs), and if so, what form these could take. This work was done in several stages: (1) Development of individual country vignettes providing an overview of HTA appraisal processes for rare disease treatments. This was done in close collaboration with HTA/reimbursement experts in each country (via a questionnaire & emails with follow-up questions and validation) and additional desk research. These vignettes are now publicly available on the IMPACT-HTA website https://www.impact-hta.eu/country-vignettes.
 (2) Peer review publication providing an overview of existing supplemental processes for rare disease treatments in the study countries (soon to be submitted to Orphanet Journal of Rare Diseases). This work characterises the different types of supplemental processes identified for rare disease treatments, and their features and potential impact on decision-making. This was used to further the debate about whether there is a need for supplemental processes for appraisal/reimbursement of rare disease treatments, and what form these could take.
 (3) Additional work is being done illustrate the impact of these supplemental processes in practice. This is being done through case study analyses, which aim to identify and contrast the impact of these supplemental processes across a number of countries with and without supplemental processes. This report is a H2020 project deliverable outlining what has been done and summarising key results.

description: We report a molecular dynamics simulation of selenium, described by a three-body interaction. The temperatures T_g and T_c and the structural properties are in agreement with experiment. The mean nearest neighbor coordination number is 2.1. A small pre-peak at about 1 AA^-1 can be explained in terms of void correlations. In the intermediate self-scattering function, i.e. the density fluctuation correlation, classical behavior, alpha- and beta-regimes, is found. We also observe the plateau in the beta-regime below T_g. In a second step, we investigated the heterogeneous and/or homogeneous behavior of the relaxations. At both short and long times the relaxations are homogeneous (or weakly heterogeneous). In the intermediate time scale, lowering the temperature increases the heterogeneity. We connect these different domains to the vibrational (ballistic), beta- and alpha-regimes. We have also shown that the increase in heterogeneity can be understood in terms of relaxations.

description: We present a comprehensive small angle neutron scattering study of the doping dependence of the helimagnetic correlations in Mn$_{1-x}$Fe$_{x}$Si. The long-range helimagnetic order in Mn$_{1-x}$Fe$_x$Si is suppressed with increasing Fe content and disappears for $x$ $>$ $x^*$ $\approx$ 0.11, i.e. well before $x_C$ $\approx$ 0.17 where the transition temperature vanishes. For $x$ $>$ $x^*$, only finite isotropic helimagnetic correlations persist which bear similarities with the magnetic correlations found in the precursor phase of MnSi. Magnetic fields gradually suppress and partly align these short-ranged helimagnetic correlations along their direction through a complex magnetization process.

description: We examine the network of forces to be expected in a static assembly of hard, frictionless spherical beads of random sizes, such as a colloidal glass. Such an assembly is minimally connected: the ratio of constraint equations to contact forces approaches unity for a large assembly. However, the bead positions in a finite subregion of the assembly are underdetermined. Thus to maintain equilibrium, half of the exterior contact forces are determined by the other half. We argue that the transmission of force may be regarded as unidirectional, in contrast to the transmission of force in an elastic material. Specializing to sequentially deposited beads, we show that forces on a given buried bead can be uniquely specified in terms of forces involving more recently added beads. We derive equations for the transmission of stress averaged over scales much larger than a single bead. This derivation requires the Ansatz that statistical fluctuations of the forces are independent of fluctuations of the contact geometry. Under this Ansatz, the $d(d+1)/2$-component stress field can be expressed in terms of a d-component vector field. The procedure may be generalized to non-sequential packings. In two dimensions, the stress propagates according to a wave equation, as postulated in recent work elsewhere. We demonstrate similar wave-like propagation in higher dimensions, assuming that the packing geometry has uniaxial symmetry. In macroscopic granular materials we argue that our approach may be useful even though grains have friction and are not packed sequentially.=17

description: Attenuating the strength of fearful memories could benefit people disabled by memories of past trauma. Pavlovian conditioning experiments indicate that a retrieval cue can return a conditioned aversive memory to a labile state. However, means to enhance retrieval and render a memory more labile are unknown. We hypothesized that augmenting synaptic signaling during retrieval would increase memory lability. To enhance synaptic transmission, mice inhaled CO2 to induce an acidosis and activate acid sensing ion channels. Transient acidification increased the retrieval-induced lability of an aversive memory. The labile memory could then be weakened by an extinction protocol or strengthened by reconditioning. Coupling CO2 inhalation to retrieval increased activation of amygdala neurons bearing the memory trace and increased the synaptic exchange from Ca2+-impermeable to Ca2+-permeable AMPA receptors. The results suggest that transient acidosis during retrieval renders the memory of an aversive event more labile and suggest a strategy to modify debilitating memories.

description: At interfaces with inversion symmetry breaking, Rashba effect couples the motion of electrons to their spin; as a result, spin-charge interconversion mechanism can occur. These interconversion mechanisms commonly exploit Rashba spin splitting at the Fermi level by spin pumping or spin torque ferromagnetic resonance. Here, we report evidence of significant photoinduced spin to charge conversion via Rashba spin splitting in an unoccupied state above the Fermi level at the Cu(111)/$α$-Bi$_{2}$O$_{3}$ interface. We predict an average Rashba coefficient of $1.72\times 10^{-10}eV.m$ at 1.98 eV above the Fermi level, by fully relativistic first-principles analysis of the interfacial electronic structure with spin orbit interaction. We find agreement with our observation of helicity dependent photoinduced spin to charge conversion excited at 1.96 eV at room temperature, with spin current generation of $J_{s}=10^{6}A/m^{2}$. The present letter shows evidence of efficient spin-charge conversion exploiting Rashba spin splitting at excited states, harvesting light energy without magnetic materials or external magnetic fields.

The Annulus-Filtered E and B Modes in CMBR Polarization

description: Although it has previously been recognized that the CMB polarization measurement on a sky ring is able to separate the B and E-mode patterns, we show that the rotational symmetry of the CMB polarization measurement is indeed unique, in that it enables the B and E modes to be separately measured in a simple and clean manner. The separation of B and E modes can in principle be achieved even with a single-polarization detector of arbitrary beam pattern. Based on this premise, a specific observing strategy is suggested, where the telescope scans along a sky circle with the polarimeter axis always oriented to a fixed direction with respect to the radial direction of the sky circle. The observational strategy for B-mode measurements can further be refined by choosing appropriate beam sizes to suppress the accidental E-mode leakage. We present the expected variances of the measured E and B-mode surface-brightness fluctuations as functions of the sky annulus radius and beam size. The measured peak power is expected to be up to 10% of the total power contained in the CMB polarization fluctuations for both B and E modes. The temperature-polarization, or T-E, correlation can be measured by the present method as well.

description: This report--part of a nationwide study of wholesale floral markets--includes data on 22 flower wholesalers in four major markets. In the national study, 136 floral wholesalers were interviewed in 13 markets. The wholesale flower markets in Baltimore, Washington, Atlanta, and Dallas-Fort Worth were found to be highly specialized. Carnations, chrysanthemums, gladioli, and roses account for two-thirds of total gross sales and 80 percent of sales of perishables. Approximately half the major cut flowers handled were from California. Local production accounted for about a fourth and Florida productions nearly a fifth of the volume handled. Nearly all California flowers were shipped to market by air freight. Most Florida flowers were shipped by truck. Wholesalers reported little change in type of customer or type of product sold in the past 5 years.

description: The interlayer tunneling has been studied on high quality Bi-2212 stacks of micron to the submicron lateral size. We found that low temperature and low voltage tunneling I-V characteristics can be self-consistently described by Fermi-liquid model for a d-wave superconductor with a significant contribution from coherent interlayer tunneling. The gap and pseudogap interplay with variation of temperature and magnetic field has been extracted from the I-V characteristics. We consider also the role of charging effects for submicron stacks.

description: Electroencephalography is a widely used tool for both routine examinations and follow-up to critically ill patients admitted to Intensive Care Unit (ICU) settings. Thus, this work studies the quantitative differences of the EEG performed for two groups of Brazilian individuals (n = 25 control and n = 25 coma), considering the frequency range 0 – 100 Hz. The EEG was analyzed by estimating the power spectral density and its time variations. It was found that the amplitude and topographic distribution of delta rhythms - coma group - and alpha - control - consist of the main quantitative differences within the classical neurologic range of 0 – 40 Hz, which agrees with well-establishded knowledge of the field. Accurate description of gamma and supergamma characteristics is provided, pointing out significant changes regarding the time variations of the supergamma power for comatose patients

description: The accounting profession is expanding to address broader accountability, especially in ESG issues. While accounting academia has been slow to embrace these changes, there’s a growing need for research and education on how businesses impact external factors like climate change. Accounting plays a vital role in decision-making and guiding long-term value creation. Future graduates should understand business operations, ESG impacts, and value creation, evolving from traditional financial expertise to broader business stewardship.

 Remarks. D. attemsi is a semiperegrine earthworm species found frequently also in disturbed habitats like green-houses etc. (FENDER 1982, CSUZDI et. al. 2008). It shows high morphological variability in term of coloration and the position of the first dorsal pore (FENDER 1982, ROTA & ERSÉUS 1997). The different specimens, even within a population, can be from slightly pigmented to possessing dark red-violet pigmentation and the dorsal pores are from different pre- or postclitellar positions to the complete loss of pores. The new species D. apora described by QIU & BOUCHÉ (1998) differs from D. attemsi only by its lighter pigmentation and lack of dorsal pores. However such variations occur even within a population, therefore D. apora is only a synonymous name of D. attemsi.

description: Sub-arcsecond resolution Chandra observations of Eta Carinae reveal a 40 arcsec X 70 arcsec ring or partial shell of X-ray emission surrounding an unresolved, bright, central source. The spectrum of the central source is strongly absorbed and can be fit with a high-temperature thermal continuum and emission lines. The surrounding shell is well outside the optical/IR bipolar nebula and is coincident with the Outer Shell of Eta Carinae. The X-ray spectrum of the Shell is much softer than that of the central source. The X-ray Shell is irregular and only correlates well with optical features where a bright X-ray knot coincides with a bright feature of the Outer Shell. Implications for the binary model of the central source are discussed.

description: Businesses are undergoing a fundamental transformation in response to global challenges like climate change, societal inequality, and sustainability. This shift requires a reevaluation of corporate purpose, governance, and accountability to multiple stakeholders. Traditional financial accounting is inadequate for measuring non-financial capitals like natural and social resources. Accountants must adapt to a broader concept of value creation and sustainability. Education must evolve to prepare accountants for these new challenges, enabling them to play a key role in developing sustainability standards and guiding businesses toward responsible practices.
SSwsrNet: A Semi-Supervised Few-Shot Learning Framework for Wireless Signal Recognition

description: Wireless signal recognition (WSR) is crucial in modern and future wireless communication networks since it aims to identify properties of the received signal. Although many deep learning-based WSR models have been developed, they still rely on a large amount of labeled training data. Thus, they cannot tackle the few-sample problem in the practically and dynamically changing wireless communication environment. To overcome this challenge, a novel SSwsrNet framework is proposed by using the deep residual shrinkage network (DRSN) and semi-supervised learning. The DRSN can learn discriminative features from noisy signals. Moreover, a modular semi-supervised learning method that combines labeled and unlabeled data using MixMatch is exploited to further improve the classification performance under few-sample conditions. Extensive simulation results on automatic modulation classification (AMC) and wireless technology classification (WTC) demonstrate that our proposed WSR scheme can achieve better performance than the benchmark schemes in terms of classification accuracy. This novel method enables more robust and adaptive signal recognition for next-generation wireless networks.

Stabilizing Grafted Colloids in a Polymer Melt: Favorable Enthalpic Interactions

description: The interactions between spherical colloids covered with end-grafted polymers (brushes) immersed in a polymer melt are studied theoretically. We show that attractive enthalpic interactions between the two polymer species, characterized by a negative Flory parameter (chi<0), can stabilize the colloidal dispersion. The stabilizing mechanism is a result of a structural change from a dry brush, where the melt chains do not penetrate deeply into the brush, to a wet brush, where the free chains penetrate the brush and force the grafted chains to extend into the melt.

description: Cluster headache is a primary headache disorder that can be highly disabling. In this thesis we look at the treatment landscape of cluster headache with a scoping review of preventive and acute therapies for cluster headache as identified in randomized controlled trials and two-arm observational studies. We subsequently compare these therapies where data are available using network meta-analysis of randomized trials, and we attempt subgroup analyses again where data are available for acute treatments of episodic and chronic cluster. We identify the ranking of treatments for acute cluster headache, and certain acute therapies that may be beneficial in episodic and chronic cluster headache. Based on our findings, we also identify future directions for cluster headache trials.
