description: Entanglement is one of the most fundamental features of quantum systems. In this work, we obtain the entanglement spectrum and entropy of Floquet noninteracting fermionic lattice models and build their connections with Floquet topological phases. Topological winding and Chern numbers are introduced to characterize the entanglement spectrum and eigenmodes. Correspondences between the spectrum and topology of entanglement Hamiltonians under periodic boundary conditions and topological edge states under open boundary conditions are further established. The theory is applied to Floquet topological insulators in different symmetry classes and spatial dimensions. Our work thus provides a useful framework for the study of rich entanglement patterns in Floquet topological matter.

description: A quasi-Lie scheme is a geometric structure that provides t-dependent changes of variables transforming members of an associated family of systems of first-order differential equations into members of the same family. In this note we introduce two quasi-Lie schemes for studying second-order Gambier equations in a geometric way. This allows us to study the transformation of these equations into simpler canonical forms, which solves a gap in the previous literature, and other relevant differential equations, which leads to derive new constants of motion for families of second-order Gambier equations. Additionally, we describe general solutions of certain second-order Gambier equations in terms of particular solutions of Riccati equations, linear systems, and t-dependent frequency harmonic oscillators.

description: Questo testo, frutto di un’accurata ricerca e basato anche sulle esperienze personali dell’autrice, si rivolge essenzialmente, ma non esclusivamente, ai docenti di letteratura inglese nei licei italiani. L’intento è quello di attivare una profonda riflessione sulla effettiva realtà della docenza della letteratura inglese per invitare gli insegnanti a scardinare il “canone” sia letterario, che linguistico, ancora attualmente troppo incentrato sull’insegnamento diacronico della letteratura britannica e, in qualche raro caso, americana. L’obiettivo è quello di suggerire un metodo e dei contenuti che possano contribuire ad accrescere la consapevolezza linguistico-letteraria negli adolescenti italiani attraverso l’impiego della stilistica come metodo per “mettere in dialogo” autori e brani tradizionali con gli innumerevoli scrittori in inglese dal mondo intero. Il testo si apre con un’analisi del contesto di partenza e continua con la presentazione della stilistica e dell’importanza delle letterature mondiali in lingua inglese nei programmi liceali italiani. A conclusione, vengono fornite cinque proposte didattiche. Il “dialogo tra testi” e la scoperta di voci parlanti inglese e provenienti dall’intero pianeta aiuterebbero gli adolescenti ad aprirsi ad una dimensione etica di pluralismo e cosmopolitismo coi mezzi scientifici dell’approccio stilistico.

description: We extend inner fluctuations to spectral triples that do not fulfill the first-order condition. This involves the addition of a quadratic term to the usual linear terms. We find a semi-group of inner fluctuations, which only depends on the involutive algebra A and which extends the unitary group of A. This has a key application in noncommutative spectral models beyond the Standard Model, of which we consider here a toy model.

description: In addition to the intended effects, the increasing use of artificial outdoor lighting also entails a number of undesirable side effects referred to as light pollution. Artificial lighting can disturb the circadian rhythms of humans and animals, which are controlled by the change of day and night, and is suspected of being involved in the development of various diseases. Moreover, the increasing illumination of the night influences the natural behaviour of animals. Besides habitat changes, the consequences are ranging from changes in hunting or reproductive behaviour to the deadly attraction effect of light sources, e. g. for insects. However, the longterm consequences of these changes for entire populations, communities or landscapes are still poorly understood. Options for reducing light pollution exist both technologically and in terms of regulation and approval of lighting installations.

description: We consider a two-dimensional electron system subjected to a short-ranged nonmagnetic disorder potential, Coulomb interactions, and Rashba spin-orbit coupling. The path-integral approach incorporated within the Keldysh formalism is used to derive the kinetic equation for the semiclassical Green's function and applied to compute the spin current within the linear response theory. We discuss the frequency dependence of the spin Hall conductivity and further elucidate the role of electron interactions at finite temperatures for both the ballistic and diffusive regimes of transport. We argue that interaction corrections to the spin Hall effect stem from the quantum interference processes whose magnitude is estimated in terms of parameters of the considered model.

description: We investigate the behavior of the periodic Anderson model in the presence of $d$-$f$ Coulomb interaction ($U_{df}$) using mean-field theory, variational calculation, and exact diagonalization of finite chains. The variational approach based on the Gutzwiller trial wave function gives a critical value of $U_{df}$ and two quantum critical points (QCPs), where the valence susceptibility diverges. We derive the critical exponent for the valence susceptibility and investigate how the position of the QCP depends on the other parameters of the Hamiltonian. For larger values of $U_{df}$, the Kondo regime is bounded by two first-order transitions. These first-order transitions merge into a triple point at a certain value of $U_{df}$. For even larger $U_{df}$ valence skipping occurs. Although the other methods do not give a critical point, they support this scenario.

description: We study the coupling between backward- and forward-propagating wave modes, with the same group velocity, in a composite right/left-handed nonlinear transmission line. Using an asymptotic multiscale expansion technique, we derive a system of two coupled nonlinear Schr{ö}dinger equations governing the evolution of the envelopes of these modes. We show that this system supports a variety of backward- and forward propagating vector solitons, of the bright-bright, bright-dark and dark-bright type. Performing systematic numerical simulations in the framework of the original lattice that models the transmission line, we study the propagation properties of the derived vector soliton solutions. We show that all types of the predicted solitons exist, but differ on their robustness: only bright-bright solitons propagate undistorted for long times, while the other types are less robust, featuring shorter lifetimes. In all cases, our analytical predictions are in a very good agreement with the results of the simulations, at least up to times of the order of the solitons' lifetimes.

description: The orbits of satellite galaxies encode rich information about their histories. We investigate the orbital dynamics and histories of satellite galaxies around Milky Way (MW)-mass host galaxies using the FIRE-2 cosmological simulations, which, as previous works have shown, produce satellite mass functions and spatial distributions that broadly agree with observations. We first examine trends in orbital dynamics at z = 0, including total velocity, specific angular momentum, and specific total energy: the time of infall into the MW-mass halo primarily determines these orbital properties. We then examine orbital histories, focusing on the lookback time of first infall into a host halo and pericenter distances, times, and counts. Roughly 37 per cent of galaxies with Mstar < 10^7 Msun were `pre-processed' as a satellite in a lower-mass group, typically ~2.7 Gyr before falling into the MW-mass halo. Half of all satellites at z = 0 experienced multiple pericenters about their MW-mass host. Remarkably, for most (67 per cent) of these satellites, their most recent pericenter was not their minimum pericenter: the minimum typically was ~40 per cent smaller and occurred ~6 Gyr earlier. These satellites with growing pericenters appear to have multiple origins: for about half, their specific angular momentum gradually increased over time, while for the other half, most rapidly increased near their first apocenter, suggesting that a combination of a time-dependent MW-mass halo potential and dynamical perturbations in the outer halo caused these satellites' pericenters to grow. Our results highlight the limitations of idealized, static orbit modeling, especially for pericenter histories.

description: We study models where the gauge coupling constants, masses, etc are functions of some conserved charge in the universe. We first consider the standard Dirac action, but where the mass and the electromagnetic coupling constant are a function of the charge in the universe and afterwards extend this scalar fields. For Dirac field in the flat space formulation, the formalism is not manifestly Lorentz invariant, however Lorentz invariance can be restored by performing a phase transformation of the Dirac field. In the case where scalar field are considered, there is the new feature that an initial condition for the scalar field is derived from the action. In the case of the Higgs field, the initial condition require, that the universe be at the false vacuum state at a certain time slice, which is quite important for inflation scenarios. Also false vacuum branes will be studied in a similar approach. We discuss also the use of "spoiling terms", that violate gauge invariant to introduce these initial condition.

description: Brain tumor segmentation remains a challenge in medical image segmentation tasks. With the application of transformer in various computer vision tasks, transformer blocks show the capability of learning long-distance dependency in global space, which is complementary with CNNs. In this paper, we proposed a novel transformer-based generative adversarial network to automatically segment brain tumors with multi-modalities MRI. Our architecture consists of a generator and a discriminator, which are trained in min-max game progress. The generator is based on a typical "U-shaped" encoder-decoder architecture, whose bottom layer is composed of transformer blocks with resnet. Besides, the generator is trained with deep supervision technology. The discriminator we designed is a CNN-based network with multi-scale $L_{1}$ loss, which is proved to be effective for medical semantic image segmentation. To validate the effectiveness of our method, we conducted experiments on BRATS2015 dataset, achieving comparable or better performance than previous state-of-the-art methods.

description: Ferroelectric polar displacements have recently been observed in conducting electron-doped BaTiO3. The co-existence of a ferroelectric phase and conductivity opens the door to new functionalities which may provide a unique route for novel device applications. Using first-principles methods and electrostatic modeling we explore the effect that the switchable polarization of electron-doped BaTiO3 (n-BaTiO3) has on the electronic properties of the SrRuO3/n-BaTiO3 (001) interface. Ferroelectric polarization controls the accumulation or depletion of electron charge at the interface, and the associated bending of the n-BTO conduction band determines the transport regime across the interface. The interface exhibits a Schottky tunnel barrier for one polarization orientation, whereas an Ohmic contact is present for the opposite polarization orientation, leading to a large change in interface resistance associated with polarization reversal. Calculations reveal a large (five orders of magnitude) change in the interface resistance as a result of polarization switching.

Verglichen wurden Studierende aus drei gesundheitsbezogenen Studiengängen, wobei keine signifikanten Unterschiede zwischen den Gruppen festgestellt wurden. Trotz der hohen Anzahl an Stunden, die im Sitzen verbracht wurden, zeigte sich eine moderate bis hoch ausgeprägte körperliche Aktivität. In der vorliegenden Studie wird versucht die Ergebnisse anhand einer ähnlichen Stichprobe zu replizieren, um zu überprüfen, ob dieses Aktivitätsniveau auch in einem anderen gesundheitsorientierten Studiengang wiederzufinden ist. Hierfür werden sowohl die verwendeten Materialien, als auch die Auswertungsmethoden so genau wie möglich auf die aktuelle Analyse übertragen.
The too-much-married man : male bigamy prosecutions in Scotland, 1837-1901

description: This thesis provides the first research into male bigamy in Scotland, examining criminal prosecutions between 1837 and 1901. Drawing on the records of the criminal courts, newspapers and a variety of other sources, it identifies how Scotland's separate legal and criminal justice system impacted on the definition, prosecution and punishment of the offence. The study addresses three key research aims: how did this separate legal context, in particular the definition of the crime and the marital law framework, affect the technical aspects of bigamy in Scotland; how did social and economic factors provide an impetus for the growth in prosecutions; and how did the criminal justice system respond to cases of bigamy? The continued legal validity of irregular marriage might be expected to facilitate bigamy, yet this research finds that it was not the major cause of prosecuted cases. It also suggests greater nuance to the argument that the era's highly restricted divorce processes fostered bigamy. Examining the physical and social geography of the crime, the study establishes that this was almost exclusively a working-class offence, disproportionately concentrated in the expanding cities. The research also posits a typology of male offenders, finding that bigamists ranged from the 'unintentional' who misunderstood the law, to the 'fickle' unable to settle in one relationship and place, to those with a wider criminal history. For the courts, the essence of the crime lay in the betrayal of the marriage vows made to the lawful wife, the deception of the second and the implications for the essential role that matrimony was seen to play in maintaining the stability of society. Punishment ranged from transportation to imprisonment, yet as the century progressed those same courts demonstrated a greater willingness to take the circumstances of individual cases into account.

description: A natural combination of the first and second derivatives of the scalar potential was achieved in a framework of an alternative refined de Sitter conjecture recently proposed in the literature. In this work, we study various inflation models in which the inflaton is a composite field emerging from various strongly interacting field theories. We then examine if these three models of inflation can satisfy this further refining de Sitter swampland conjecture or not. Regarding our analysis with proper choices of parameters $a,\,b=1- a$ and $q$, we find that some inflationary models are in strong tension with the refined Swampland conjecture. However, all of them can always satisfy the alternative refined de Sitter conjecture. Therefore, one may expect that all inflationary models might all be in landscape since the further refining de Sitter swampland conjecture is satisfied.

description: Body Mass Index (BMI; weight scaled by squared height) is a crucial determinant of physical attractiveness, potentially because BMI signals mate value. Yet, BMI does not contain information about body composition, namely fat and muscle, which might be a better indication of mate value. The current thesis explored the potential influence of body composition on attractiveness and other social judgements. Study 1 investigated the influence of facial correlates of body composition on perceived male facial masculinity. Facial correlates of muscle consistently enhanced facial masculinity, whereas facial correlates of fat increased masculinity perception in underweight to normal-weight men only. Study 2 investigated women’s preferences for facial correlates of body composition in short- and long-term relationships. Women have stronger preferences for facial correlates of muscle in short- compared to long-term relationships, while no discrepancy was observed in preferences for facial correlates of fat. Study 3 investigated how body composition influences health and kindness judgements from male faces. Perceived health increased with increasing fat and muscle from underweight to normal-weight men but decreased with further increases in fat and muscle. Increase in facial correlates of muscle dramatically diminished perceived kindness, but facial correlates of fat showed a slight detrimental impact on perceived kindness. Study 4 investigated whether men and women have accurate perceptions of opposite- sex preferences for body shape. Women exaggerated the thinness that men prefer; men exaggerated the heaviness and muscularity that women prefer. Moreover, these misperceptions were larger for short- compared to long-term relationships. The thesis demonstrates the distinct effects of fat and muscle on social judgements and reveals that men and women misperceive opposite-sex preferences. These findings point out the importance of distinguishing body composition of studies of body size.

description: We propose a nuclear-spin-polarization protocol in a general evolution-and-measurement framework. The protocol works in a spin-star configuration, where the central spin is coupled to the surrounding bath (nuclear) spins by flip-flop interaction of equal strength and is subject to a sequence of projective measurements on its ground state. Then a nondeterministic nuclear spin polarization could be implemented by entropy reduction through measurement. The optimized measurement-interval $τ_{\rm opt}$ is analytically obtained in the near-resonant condition, which is relevant to the nuclear spins' polarization degree of the last-round measurement, the number of nuclear spins, and the coupling strength between the central spin and nuclear spins. Hundreds and even thousands of randomly aligned nuclear spins at the thermal state could be almost fully polarized with an optimized sequence of less than $20$ unequal-time-spacing measurements. In comparison to the conventional approaches, our protocol is not sensitive to the magnetic-field intensity, and it is robust against the extra counterrotating interaction in the near-resonant situation.

description: The type III Hermite $X_m$ exceptional orthogonal polynomial family is generalized to a double-indexed one $X_{m_1,m_2}$ (with $m_1$ even and $m_2$ odd such that $m_2 > m_1$) and the corresponding rational extensions of the harmonic oscillator are constructed by using second-order supersymmetric quantum mechanics. The new polynomials are proved to be expressible in terms of mixed products of Hermite and pseudo-Hermite ones, while some of the associated potentials are linked with rational solutions of the Painlevé IV equation. A novel set of ladder operators for the extended oscillators is also built and shown to satisfy a polynomial Heisenberg algebra of order $m_2-m_1+1$, which may alternatively be interpreted in terms of a special type of $(m_2-m_1+2)$th-order shape invariance property.

description: Recently, it has been argued that quantum mechanics is complete, and that quantum states vectors are necessarily in one-to-one correspondence with the elements of reality, under the assumptions that quantum theory is correct and that measurement settings can be freely chosen. In this work, we argue that the adopted form of the free choice assumption is stronger than needed. We unveil hidden assumptions underlying these results, which limit their range of validity. We support our argument by a model for the bipartite two-level system, reproducing quantum mechanics, in which the free will assumption is respected, and different quantum states can be connected to the same state of reality.

description: Information on iron metabolism has been significantly supplemented and changed in recent decades. The review provides data on the main proteins involved in iron metabolism in humans. The mechanisms of iron acquisition in bacteria from the macroorganism and their importance in the development of infectious and inflammatory process in patients with cystic fibrosis are described. Data on the significance of Burkholderia cepacia complex and Pseudomonas aeruginosa siderophores in the processes of binding and transport of iron to bacterial cells are presented. The result of complex interactions of bacteria and macroorganism in cystic fibrosis can be the development of severe exacerbations, including “cepation-syndrome”, which, taking into account the above data, should be considered not only as direct damage to the lung tissue by bacteria, but also as a factor in the formation of a “vicious circle”: viscous sputum leads to infection of the lower respiratory tract with microorganisms that need iron and release it from the tissues, which can stimulate not only lung damage, but also lead to the growth of virulence of bacteria.

description: The review deals with the stages of antiviral therapy of chronic viral hepatitis C. Using different schemes of combined treatment with genetically engineered interferon drugs with ribavirin that makes the treatment so expensive, we observed the successes and failures in the effectiveness of the antiviral therapy, especially in patients with genotype 1 of C virus. The dependence of the efficiency of virologic response on many factors - liver fibrosis and cirrhosis, C virus genotype, ethnicity, as well as the genotype of the IL 28B gene and its loci – has been found out. Therapy with interferon drugs was carried out parenterally for 24 to 48 weeks and longer. In 2012–2014 direct-acting antiviral drugs (DAAs) – NS3/4A protease inhibitors boceprevir and telaprevir – came into use, followed by simeprevir, in combination with pegylated interferon-α and ribavirin for the treatment of patients with chronic viral hepatitis C with 1B and 1A virus genotype. In 2015, the Ministry of Health of the Russian Federation registered the first fully interferon-free combination for the treatment of genotype 1 chronic viral hepatitis, with the trade name of Viekira Pak consisting of 3 direct-acting antiviral drugs: dasabuvir, ombitasvir, paritaprevir, and pharmacological booster ritonavir. Such therapy has shown high efficiency, safety, convenience of use of tablet formulations, a short course of treatment, which contributed to a greater commitment of patients to treatment. Later, registered direct-acting antiviral drugs – daclatasvir and asunaprevir - found their use. The prospects are obvious, although there is still a lot of work to be done in selecting the best approaches to the treatment of all categories of patients with chronic viral hepatitis C. Key words: chronic viral hepatitis C, interferon therapy, direct-acting antiviral drugs, interferon-free therapy.

A fairly common species in Cameroon, in secondary rain forests a long fringes of forests, in swampy regions too. Altitude 100-800 m a.s.l. Local and common names known in Cameroon. None recorded. IUCN conservation status. Not evaluated. Uses in Cameroon. None recorded. Notes. Differences between var. Artabotrys insignis insignis and var. Artabotrys insignis batesii are quite small, and are mainly related to the pubescence of the branches, lower side of the leaves and petals (Le Thomas 1965a). There is one more recognized variety within Artabotrys insignis: var. Artabotrys insignis concolor (Pellegr.) Le Thomas which differs by having shiny leaves on both sides and longer sepals. We have not seen this variety in Cameroon, but it is present in Gabon (Le Thomas 1965a, 1969b). Specimens examined.

description: Inelastic neutron scattering measurements of paramagnetic SrCo$_{2}$As$_{2}$ at T=5 K reveal antiferromagnetic (AFM) spin fluctuations that are peaked at a wavevector of $\textbf{Q}_{\mathrm{AFM}}=(1/2,1/2,1)$ and possess a large energy scale. These stripe spin fluctuations are similar to those found in $A$Fe$_{2}$As$_{2}$ compounds, where spin-density wave AFM is driven by Fermi surface nesting between electron and hole pockets separated by $\textbf{Q}_{\mathrm{AFM}}$. SrCo$_{2}$As$_{2}$ has a more complex Fermi surface and band structure calculations indicate a potential instability towards either a ferromagnetic or stripe AFM ground state. The results suggest that stripe AFM magnetism is a general feature of both iron and cobalt-based arsenides and the search for spin fluctuation-induced unconventional superconductivity should be expanded to include cobalt-based compounds.

Quantized topological terms in weak-coupling gauge theories with symmetry and their connection to symmetry enriched topological phases

description: We study the quantized topological terms in a weak-coupling gauge theory with gauge group $G_g$ and a global symmetry $G_s$ in $d$ space-time dimensions. We show that the quantized topological terms are classified by a pair $(G,ν_d)$, where $G$ is an extension of $G_s$ by $G_g$ and $ν_d$ an element in group cohomology $\cH^d(G,\R/\Z)$. When $d=3$ and/or when $G_g$ is finite, the weak-coupling gauge theories with quantized topological terms describe gapped symmetry enriched topological (SET) phases (i.e. gapped long-range entangled phases with symmetry). Thus, those SET phases are classified by $\cH^d(G,\R/\Z)$, where $G/G_g=G_s$. We also apply our theory to a simple case $G_s=G_g=Z_2$, which leads to 12 different SET phases in 2+1D, where quasiparticles have different patterns of fractional $G_s=Z_2$ quantum numbers and fractional statistics. If the weak-coupling gauge theories are gapless, then the different quantized topological terms may describe different gapless phases of the gauge theories with a symmetry $G_s$, which may lead to different fractionalizations of $G_s$ quantum numbers and different fractional statistics (if in 2+1D).

The Drastic Role of Beyond Nearest-Neighbor Interactions on Two-Dimensional Dynamical Lattices: A Case Example

description: In the present work, we highlight the significant effect that the simplest beyond nearest neighbor interactions can have on two-dimensional dynamical lattices. To do so, we select as our case example the closest further neighbor, namely the diagonal one, and a prototypical nonlinear lattice, the discrete nonlinear Schrodinger equation. Varying solely the strength of this extra neighbor interaction, we see examples of (a) destabilization of states that start out as stable in the nearest neighbor limit; (b) stabilization of states that start out as unstable in that limit; (c) bifurcation of novel states that do not exist in the nearest neighbor case. These dramatic changes are first theoretically highlighted through an analysis of a reduction of the problem to a few excited sites and the associated set of conditions that govern their existence and their dynamical stability. Then, they are corroborated numerically through fixed point computations, spectral analysis and nonlinear dynamical evolution simulations.

description: Topology, symmetry, electron correlations, and the interplay between them have formed the cornerstone of our understanding of quantum materials in recent years and are used to identify new emerging phases. While the first two give a fair understanding of noninteracting and, in many cases, weakly interacting wave function of electron systems, the inclusion of strong correlations could change the picture substantially. The Kondo lattice model is a paradigmatic example of the interplay of electron correlations and conduction electrons of a metallic system, describing heavy fermion materials and also fractionalized Fermi liquid pertaining to an underlying gauge symmetry and topological orders. In this work, we study a superconducting Kondo lattice model, a network of 1D Kitaev superconductors Kondo coupled to a lattice of magnetic moments. Using slave-particle representation of spins and exact numerical calculations, we obtain the phase diagram of the model in terms of Kondo coupling $J_K$ and identify a topological order phase for $J_{K}J_{K}^c$, where $J_{K}^c$ is the critical point. Setting the energy scales of electron hopping and pairing to unity, the mean-field theory calculations achives $J_{K}^c=2$ and in exact numerics we found $J_{K}^c\simeq 1.76$, both of which show that the topological order is a robust phase. We argue that in terms of slave particles, the compensated phase corresponds to an invertible phase, and a Mott insulating transition leads to a topological order phase. Furthermore, we show that in the regime $J_{K}

description: We study in detail the dynamics of a scalar field in thermal bath with symmetry breaking potential. In particular, we focus on the process of trapping of a scalar field at an enhanced symmetry point through the thermal/non-thermal particle production, taking into account the interactions of produced particles with the standard model particles. As an explicit example, we revisit the saxion dynamics with an initial amplitude much larger than the Peccei-Quinn scale and show that the saxion trapping phenomenon happens for the most cases and it often leads to thermal inflation. We also study the saxion dynamics after thermal inflation, and it is shown that thermal dissipation effect on the saxion can relax the axion overproduction problem from the saxion decay.

description: Many cognitive neuroscience studies use large feature sets to predict and interpret brain activity patterns. Feature sets take many forms, from human stimulus annotations to representations in deep neural networks. Of crucial importance in all these studies is the mapping model, which defines the space of possible relationships between features and neural data. Until recently, most encoding and decoding studies have used linear mapping models. Increasing availability of large datasets and computing resources has recently allowed some researchers to employ more flexible nonlinear mapping models instead; however, the question of whether nonlinear mapping models can yield meaningful scientific insights remains debated. Here, we discuss the choice of a mapping model in the context of three overarching desiderata: predictive accuracy, interpretability, and biological plausibility. We show that, contrary to popular intuition, these desiderata do not map cleanly onto the linear/nonlinear divide; instead, each desideratum can refer to multiple research goals, each of which imposes its own constraints on the mapping model. Moreover, we argue that, instead of categorically treating the mapping models as linear or nonlinear, we should instead aim to estimate the complexity of these models. We show that, in many cases, complexity provides a more accurate reflection of restrictions imposed by various research goals. Finally, we outline several complexity metrics that can be used to effectively evaluate mapping models.

description: Using the off-shell formulation for N-extended conformal supergravity in three dimensions, which has recently been presented in arXiv:1305.3132, we construct superspace actions for conformal supergravity theories with N<6. For each of the cases considered, we work out the complete component action as well as the gauge transformation laws of the fields belonging to the Weyl supermultiplet. The N=1 and N=2 component actions derived coincide with those proposed by van Nieuwenhuizen and Rocek in the mid-1980s. The off-shell N=3, N=4 and N=5 supergravity actions are new results. Upon elimination of the auxiliary fields, these actions reduce to those constructed by Lindstrom and Rocek in 1989 (and also by Gates and Nishino in 1993).
