description: Context: Many thermally emitting isolated neutron stars have magnetic fields larger than 10^13 G. A realistic cooling model that includes the presence of high magnetic fields should be reconsidered. Aims: We investigate the effects of anisotropic temperature distribution and Joule heating on the cooling of magnetized neutron stars. Methods: The 2D heat transfer equation with anisotropic thermal conductivity tensor and including all relevant neutrino emission processes is solved for realistic models of the neutron star interior and crust. Results: The presence of the magnetic field affects significantly the thermal surface distribution and the cooling history during both, the early neutrino cooling era and the late photon cooling era. Conclusions: There is a large effect of the Joule heating on the thermal evolution of strongly magnetized neutron stars. Both magnetic fields and Joule heating play a key role in keeping magnetars warm for a long time. Moreover, this effect is important for intermediate field neutron stars and should be considered in radio-quiet isolated neutron stars or high magnetic field radio-pulsars.

description: Perturbative estimates suggest that extended topological defects such as cosmic strings emit few particles, but numerical simulations of the fields from which they are constructed suggest the opposite. In this paper we study the decay of the two-dimensional prototype of strings, domain walls in a simple scalar theory, solving the underlying quantum field theory in the Hartree approximation. We conclude that including the quantum effects makes the picture clear: the defects do not directly transform into particles, but there is a non-perturbative channel to microscopic classical structures in the form of propagating waves and persistent localised oscillations, which operates over a huge separation of scales. When quantum effects are included, the microscopic classical structures can decay into particles.

description: The Pr55Gag precursor specifically selects the HIV-1 genomic RNA (gRNA) from a large excess of cellular and partially or fully spliced viral RNAs and drives the virus assembly at the plasma membrane. During these processes, the NC domain of Pr55Gag interacts with the gRNA, while its C-terminal p6 domain binds cellular and viral factors and orchestrates viral particle release. Gag∆p6 is a truncated form of Pr55Gag lacking the p6 domain usually used as a default surrogate for wild type Pr55Gag for in vitro analysis. With recent advance in production of full-length recombinant Pr55Gag, here, we tested whether the p6 domain also contributes to the RNA binding specificity of Pr55Gag by systematically comparing binding of Pr55Gag and Gag∆p6 to a panel of viral and cellular RNAs. Unexpectedly, our fluorescence data reveal that the p6 domain is absolutely required for specific binding of Pr55Gag to the HIV-1 gRNA. Its deletion resulted not only in a decreased affinity for gRNA, but also in an increased affinity for spliced viral and cellular RNAs. In contrast Gag∆p6 displayed a similar affinity for all tested RNAs. Removal of the C-terminal His-tag from Pr55Gag and Gag∆p6 uniformly increased the Kd values of the RNA-protein complexes by ~ 2.5 fold but did not affect the binding specificities of these proteins. Altogether, our results demonstrate a novel role of the p6 domain in the specificity of Pr55Gag-RNA interactions, and strongly suggest that the p6 domain contributes to the discrimination of HIV-1 gRNA from cellular and spliced viral mRNAs, which is necessary for its selective encapsidation.

description: Background: Appendicularia consists of approximately 70 purely marine species that belong to Tunicata the probable sister taxon to Craniota. Therefore, Appendicularia plays a pivotal role for our understanding of chordate evolution. In addition, appendicularians are an important part of the epipelagic marine plankton. Nevertheless, little is known about appendicularian species, especially from deeper water. Results: Using µCT, scanning electron microscopy, and digital 3D-reconstruction techniques we describe three pairs of complex oral sensory organs in the mesopelagic appendicularian Bathochordaeus stygius. The oral sensory organs are situated at the anterior and lateral margin of the mouth and inside the mouth cavity. A single organ consists of 22–90 secondary receptor cells that project apical cilia through a narrow hole in the epidermis. The receptor cells are innervated by branches of the second brain nerve. Conclusions: Based on position, morphology, and innervation we suggest that the oral sensory organs are homologues of the coronal organs in other tunicates. We discuss the hypothesized homology of coronal organs and the lateral line system of primary aquatic vertebrates. The complex oral sensory organs of B. stygius are unique in tunicates and could be adaptations to the more muffled environment of the mesopelagic.

description: We analyze the static and dynamical properties of a one-dimensional topological lattice, the fermionic Su-Schrieffer-Heeger model, in the presence of on-site interactions. Based on a study of charge and spin correlation functions, we elucidate the nature of the topological edge modes, which depending on the sign of the interactions, either display particles of opposite spin on opposite edges, or a pair and a holon. This study of correlation functions also highlights the strong entanglement that exists between the opposite edges of the system. This last feature has remarkable consequences upon subjecting the system to a quench, where an instantaneous edge-to-edge signal appears in the correlation functions characterizing the edge modes. Besides, other correlation functions are shown to propagate in the bulk according to the light-cone imposed by the Lieb-Robinson bound. Our study reveals how one-dimensional lattices exhibiting entangled topological edge modes allow for a non-trivial correlation spreading, while providing an accessible platform to detect spin-charge separation using state-of-the-art experimental techniques.

description: We investigate Planck scale boundary conditions on Higgs quartic interactions and their $β$-functions in the SM augmented by an additional complex scalar. We use renormalisation group running at two-loops, and include both theoretical and experimental constraints. We find that the boundary condition $λ=β_λ=0$ at the Planck scale is compatible with the current Higgs and top mass measurements, but requires additional scalars lighter than about $600\,$GeV.

description: Empirically derived continuum models of collective behavior among large populations of dynamic agents are a subject of intense study in several fields, including biology, engineering and finance. We formulate and study a mean-field game model whose behavior mimics an empirically derived non-local homogeneous flocking model for agents with gradient self-propulsion dynamics. The mean-field game framework provides a non-cooperative optimal control description of the behavior of a population of agents in a distributed setting. In this description, each agent's state is driven by optimally controlled dynamics that result in a Nash equilibrium between itself and the population. The optimal control is computed by minimizing a cost that depends only on its own state, and a mean-field term. The agent distribution in phase space evolves under the optimal feedback control policy. We exploit the low-rank perturbative nature of the non-local term in the forward-backward system of equations governing the state and control distributions, and provide a linear stability analysis demonstrating that our model exhibits bifurcations similar to those found in the empirical model. The present work is a step towards developing a set of tools for systematic analysis, and eventually design, of collective behavior of non-cooperative dynamic agents via an inverse modeling approach.

description: In the low-velocity limit, multi-soliton solutions trace out geodesics in the static solution manifold with distance defined by a metric on moduli space. For the recently constructed multimonopole solutions of heterotic string theory, we obtain a flat metric to leading order in the impact parameter. This result agrees with the trivial scattering predicted by a test monopole calculation.

description: We perform a combined likelihood analysis for the IceCube 6-year high-energy starting events (HESE) and 8-year throughgoing muon events above 10 TeV using a two-component neutrino flux model. The two-component flux can be motivated either from purely astrophysical sources or due to a beyond Standard Model contribution, such as decaying heavy dark matter. We find that the astrophysical plus dark matter interpretation is mildly preferred by the current data over the purely astrophysical explanation. As for the astrophysical neutrinos, we consider two different source flavor compositions corresponding to the standard pion decay and muon-damped pion decay sources. We find that the latter is slightly preferred over the former as the high-energy component, while the low-energy component does not show any such preference. We also take into account the multi-messenger gamma-ray constraints and find that our two-component fit is compatible with these constraints, whereas the single-component power-law bestfit to the HESE data is ruled out. The astrophysical plus dark matter interpretation of the two-component flux is found to be mildly preferred by the current data and the gamma-ray constraints over the purely astrophysical explanation.

description: The Ataxia-telangiectasia mutated (ATM) kinase and the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) are activated by DNA double-strand breaks (DSBs). These DSBs occur in the context of chromatin but how chromatin influences the activation of these kinases is not known. Here we show that loss of the replication-dependent chromatin assembly factors ASF1A/B or CAF-1 compromises ATM activation, while augmenting DNA-PKcs activation, in response to DNA DSBs. Cells deficient in ASF1A/B or CAF-1 exhibit reduced histone H4 lysine 16 acetylation (H4K16ac), a histone mark known to promote ATM activation. ASF1A interacts with the histone acetyl transferase, hMOF that mediates H4K16ac. ASF1A depletion leads to increased recruitment of DNA-PKcs to DSBs. We propose normal chromatin assembly and H4K16ac during DNA replication is required to regulate ATM and DNA-PKcs activity in response to the subsequent induction of DNA DSBs.

description: In the present work we propose that two-time correlations of Majorana edge localized fermions constitute a novel and versatile toolbox for assessing the topological phases of 1D open lattices. Using analytical and numerical calculations on the Kitaev model, we uncover universal relationships between the decay of the short-time correlations and a particular family of out-of-time-ordered correlators, which provide direct experimental alternatives to the quantitative analysis of the system regime, either normal or topological. Furthermore we show that the saturation of two-time correlations possesses features of an order parameter. Finally, we find that violations of Leggett-Garg inequalities can indicate the topological-normal phase transition by looking at different qubits formed by pairing local and non-local edge Majorana fermions.

Phase diagram of the one-dimensional extended Hubbard model with attractive and/or repulsive interactions at quarter filling

description: We study the phase diagram of the one dimensional (1D) $U-V$ model at quarter filling in the most general case where the on-site and first-neighbour interactions $U$ and $V$ can be both attractive and repulsive. The results have been obtained using exact diagonalization of small clusters and variational techniques, as well as exact results in various limits. We have analyzed four properties of the groundstate: i)~whether it is insulating or metallic; \hbox{ii)~whether} it is homogenous or phase separated; iii)~whether it has a spin gap; iv)~whether it has dominant superconducting fluctuations. With eight phases, the resulting phase diagram is unexpectedly rich. The four phases not found in the weak coupling limit are: i) an insulating phase when $U$ and $V$ are large enough; ii) a region of phase separation when $V$ is attractive; iii) another region of phase separation when $V$ is large enough and $U$ small; iv) a region with dominant superconducting fluctuations when $V$ is intermediate and $U$ small. The actual nature of this last phase, which has pairs but no spin gap, is not fully clear yet.

description: Phase field modelling offers an extremely general framework to predict microstructural evolutions in complex systems. However, its computational implementation requires a discretisation scheme with a grid spacing small enough to preserve the continuous character of the theory. We present here a new formulation, which is intrinsically discrete, in which the interfaces are resolved with essentially one grid point with no pinning on the grid and an accurate rotational invariance, improving drastically the numerical capabilities of the method. We show that interfacial kinetic properties are reproduced with a high accuracy. Finally, we apply the model to a situation where conserved and non-conserved fields are coupled.

Secular effects on inflation from one-loop quantum gravity

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper we revisit and extend a previous analysis where the possible relevance of quantum gravity effects in a cosmological setup was studied. The object of interest are non-local (logarithmic) terms generated in the effective action of gravity due to the exchange in loops of massless modes (such as photons or the gravitons themselves). We correct one mistake existing in the previous work and discuss the issue in a more general setting in different cosmological scenarios. We obtain the one-loop quantum-corrected evolution equations for the cosmological scale factor up to a given order in a derivative expansion in two particular cases: a matter dominated universe with vanishing cosmological constant, and in a de Sitter universe. We show that the quantum corrections, albeit tiny, may have a secular effect that eventually modifies the expansion rate. For a de Sitter universe they tend to slow down the rate of the expansion, while the effect seems to have the opposite sign in a matter dominated universe. To partly understand these effects we provide a complementary newtonian analysis.

description: Manipulating the electron spin with the aid of spin-orbit coupling (SOC) is an indispensable element of spintronics. Electrostatically gating a material with strong SOC results in an effective magnetic field which can in turn be used to govern the electron spin. In this work, we report the existence and electrostatic tunability of Rashba SOC in multilayer InSe. We observed a gate-voltage-tuned crossover from weak localization (WL) to weak antilocalization (WAL) effect in quantum transport studies of InSe, which suggests an increasing SOC strength. Quantitative analyses of magneto-transport studies and energy band diagram calculations provide strong evidence for the predominance of Rashba SOC in electrostatically gated InSe. Furthermore, we attribute the tendency of the SOC strength to saturate at high gate voltages to the increased electronic density of states-induced saturation of the electric field experienced by the electrons in the InSe layer. This explanation of nonlinear gate voltage control of Rashba SOC can be generalized to other electrostatically gated semiconductor nanomaterials in which a similar tendency of spin-orbit length saturation was observed (e.g. nanowire field effect transistors), and is thus of broad implications in spintronics. Identifying and controlling the Rashba SOC in InSe may serve pivotally in devising III-VI semiconductor-based spintronic devices in the future.

description: Currently, autonomous vehicles are able to drive more naturally based on the driving policies learned from millions of driving miles in real environments. However, to further improve the automation level of vehicles is a challenging task, especially in the case of multi-vehicle cooperation. In recent heated discussions of 6G, millimeter-wave (mmWave) and terahertz (THz) bands are deemed to play important roles in new radio communication architectures and algorithms. To enable reliable autonomous driving in 6G, in this paper, we envision collaborative autonomous driving, a new framework that jointly controls driving topology and formulate vehicular networks in the mmWave/THz bands. As a swarm intelligence system, the collaborative driving scheme goes beyond existing autonomous driving patterns based on single-vehicle intelligence in terms of safety and efficiency. With efficient data sharing, the proposed framework is able to achieve cooperative sensing and load balancing so that improve sensing efficiency with saved computational resources. To deal with the new challenges in the collaborative driving framework, we further illustrate two promising approaches for mmWave/THz-based vehicle-to-vehicle (V2V) communications. Finally, we discuss several potential open research problems for the proposed collaborative driving scheme.

description: The Bartnik mass is a quasi-local mass tailored to asymptotically flat Riemannian manifolds with non-negative scalar curvature. From the perspective of general relativity, these model time-symmetric domains obeying the dominant energy condition without a cosmological constant. There is a natural analogue of the Bartnik mass for asymptotically hyperbolic Riemannian manifolds with a negative lower bound on scalar curvature which model time-symmetric domains obeying the dominant energy condition in the presence of a negative cosmological constant. Following the ideas of Mantoulidis and Schoen [2016], of Miao and Xie [2016], and of joint work of Miao and the authors [2017], we construct asymptotically hyperbolic extensions of minimal and constant mean curvature (CMC) Bartnik data while controlling the total mass of the extensions. We establish that for minimal surfaces satisfying a stability condition, the Bartnik mass is bounded above by the conjectured lower bound coming from the asymptotically hyperbolic Riemannian Penrose inequality. We also obtain estimates for such a hyperbolic Bartnik mass of CMC surfaces with positive Gaussian curvature.

description: Introduction: Investigating the information seeking behavior of nursing students in General English and ESP courses is of great importance since various factors may impact the students’ information seeking behavior. As such, the present study sought the inhibitors to the information seeking behavior of students of nursing in general English and ESP courses. Methods The study is a qualitative research that adopted a conventional content analysis. Seven faculty members of English as foreign language (EFL) who took part in the interview had the experience of teaching English for specific purposes (ESP) to nursing students. The study that was carried out in 2018 used a purposive sampling and a semi-structured interview was employed in the study. Results: Based on the findings,143 themes emerged that were categorized into 19 sub categories and, 3 main categories; namely, behavioral, organizational, and contextual factors were the main obstacles to information seeking behavior of nursing students in general English and ESP courses. Conclusion: It was revealed that ignoring the factors which influence nursing students’ information seeking behavior may result in either students’ over- reliance on their textbooks or on their attempt to translate textbook. By so doing, they would not seek help from various other information resources. It seems necessary to pay a particular attention to the factors. By doing so, one can have a better understanding of students' information seeking behavior.

description: An action for two dimensional gravity conformally coupled to two dilaton-type fields is analysed. Classically, the theory has some exact solutions. These include configurations representing black holes. A semi-classical theory is obtained by assuming that these singular solutions are caused by the collapse of some matter fields. The semi-classical equations of motion reveal then that any generic solution must have a flat geometry.

description: Many dynamic programming algorithms for discrete 0-1 optimizationproblems are "pure" in that their recursion equations only use min/max and addition operations, and do not depend on actual input weights. The well-known greedy algorithm of Kruskal solves the minimum weight spanning tree problem on $n$-vertex graphs using only $O(n^2\log n)$ operations. We prove that any pure DP algorithm for this problem must perform $2^{Ω(\sqrt{n})}$ operations. Since the greedy algorithm can also badly fail on some optimization problems, easily solvable by pure DP algorithms, our result shows that the computational powers of these two types of algorithms are incomparable.
description: The first structural claim of the Forest lemma (that the sets of vertices in the connected components of all forests from one side must be the same) in the previous version is just wrong. We now use entirely different arguments to prove a slightly weaker version of the numerical claim of the Forest lemma. The resulting lower bound is weaker, but still exponential

description: We obtain a simple two-sided inequality for the ratio $\mathbf{L}_ν(x)/\mathbf{L}_{ν-1}(x)$ in terms of the ratio $I_ν(x)/I_{ν-1}(x)$, where $\mathbf{L}_ν(x)$ is the modified Struve function of the first kind and $I_ν(x)$ is the modified Bessel function of the first kind. This result allows one to use the extensive literature on bounds for $I_ν(x)/I_{ν-1}(x)$ to immediately deduce bounds for $\mathbf{L}_ν(x)/\mathbf{L}_{ν-1}(x)$. We note some consequences and obtain further bounds for $\mathbf{L}_ν(x)/\mathbf{L}_{ν-1}(x)$ by adapting techniques used to bound the ratio $I_ν(x)/I_{ν-1}(x)$. We apply these results to obtain new bounds for the condition numbers $x\mathbf{L}_ν'(x)/\mathbf{L}_ν(x)$, the ratio $\mathbf{L}_ν(x)/\mathbf{L}_ν(y)$ and the modified Struve function $\mathbf{L}_ν(x)$ itself. Amongst other results, we obtain two-sided inequalities for $x\mathbf{L}_ν'(x)/\mathbf{L}_ν(x)$ and $\mathbf{L}_ν(x)/\mathbf{L}_ν(y)$ that are given in terms of $xI_ν'(x)/I_ν(x)$ and $I_ν(x)/I_ν(y)$, respectively, which again allows one to exploit the substantial literature on bounds for these quantities. The results obtained in this paper complement and improve existing bounds in the literature.

description: We propose a new example of entanglement knitting spacetime together, satisfying a series of checks of the corresponding von Neumann and Renyi entropies. The conjectured dual of de Sitter in d+1 dimensions involves two coupled CFT sectors constrained by residual d-dimensional gravity. In the d=2 case, the gravitational constraints and the CFT spectrum are relatively tractable. We identify a finite portion of each CFT Hilbert space relevant for de Sitter. Its maximum energy level coincides with the transition to the universal Cardy behavior for theories with a large central charge and a sparse light spectrum, derived by Hartman, Keller, and Stoica. Significant interactions between the two CFTs, derived previously for other reasons, suggest a maximally mixed state upon tracing out one of the two sectors; we derive this by determining the holographic Renyi entropies. The resulting entanglement entropy matches the Gibbons-Hawking formula for de Sitter entropy, including the numerical coefficient. Finally, we interpret the Gibbons-Hawking horizon entropy in terms of the Ryu-Takayanagi entropy, and explore the time evolution of the entanglement entropy.

description: Study and research path (SRP) is an inquiry-based teaching format grounded in the Anthropological Theory of the Didactic. One of the specific characteristics of SRP is its task-design basis, which includes explicitly questioning the knowledge at stake in study processes. In this work, we propose general guidelines for the design of SRPs for Engineering courses. We have explored the validity of the SRP methodology for learning Strength of Materials, a key subject in Mechanical Engineering. The use of question–answer maps and the media–milieu dialectics throughout the development of the SRP are discussed, together with the student’s perceptions on the new learning process.

description: Abstract

The development and dissemination of integrated reporting has solved the inadequacy of financial reporting and the burden of presenting sustainability reporting separately. The development and dissemination of integrated reporting has solved the inadequacy of financial reporting and the burden of presenting sustainability reporting separately. Academic studies have played an important role in this field. Academic studies analysing and evaluating published integrated reports can improve their quality. Bibliometric analysis of such studies aims to create a resource for scientists to conduct new research by identifying gaps and making comparisons and analyses. Additionally, through a systematic review of the literature, this aims to evaluate the role attributed to integrated reporting and computer technology in sustainable business models.The study analysed 330 articles and found that only one article had been published in this field until 2011, after which the number of publications increased. The years with the highest number of articles published were 2020 and 2022. The journal that published the highest number of articles on this theme was Sustainability (Switzerland). The authors who published the most articles were Maroun, W., De Villiers, C., and Dumay, J. The most frequently used keywords were integrated reporting and sustainability. The institution that published the most articles was the University of the Witwatersrand, and the country with the highest number of citations was Italy.
Helicity-protected domain-wall magnetoresistance in ferromagnetic Weyl semimetal

description: The magnetotransport properties of disordered ferromagnetic Weyl semimetals are investigated numerically. We found an extraordinarily stable and huge magnetoresistance effect in domain walls of Weyl semimetals. This effect originates from the helicity mismatch of Weyl fermions and is a specific property of Weyl semimetals. Although conventional magnetoresistance effects are strongly suppressed in domain walls where local magnetization varies gradually, the helicity-protected magnetoresistance in Weyl semimetals maintains almost $100\%$ of the magnetoresistance ratio for any kind of thick domain walls, even in the presence of disorder. The contribution of surface Fermi arcs to the magnetoresistance is also discussed.

description: A cetirizine hydrochloride PVC membrane drug sensor was developed by using the ion association complex produced with sodium tetra phenyl borate and cetirizine hydrochloride as electroactive substance. In sodium dihydrogen phosphate-sodium hydroxide buffer solution of pH 5.0, the linear range of the sensor is 1.58×10-6~1.0×10-1 mol/L, the slope is 46mV/pC (20°C) and the detection limit is 6.31×10-7 mol/L. The sensor has fast response and good reproducibility. Using the sensor for the determination of cetirizine hydrochloride in drugs, the relative standard deviation is less than 3% and the results are consistent with the labeled content in preparations.

description: Nanopore sensing is a versatile technique for the analysis of molecules on the single-molecule level. However, extracting information from data with established algorithms usually requires time-consuming checks by an experienced researcher due to inherent variability of solid-state nanopores. Here, we develop a convolutional neural network (CNN) for the fully automated extraction of information from the time-series signals obtained by nanopore sensors. In our demonstration, we use a previously published dataset on multiplexed single-molecule protein sensing. The neural network learns to classify translocation events with greater accuracy than previously possible, while also increasing the number of analysable events by a factor of five. Our results demonstrate that deep learning can achieve significant improvements in single molecule nanopore detection with potential applications in rapid diagnostics.

description: Monopole-mediated baryon number violation, the Callan-Rubakov effect, is reexamined using boundary conformal field theory techniques. It is shown that the low-energy behaviour is described simply by free fermions with a conformally invariant boundary condition at the dyon location. When the number of fermion flavours is greater than two, this boundary condition is of a non-trivial type which has not been elucidated previously.

description: The complex compounds of diiron (II) bisbenzoll, 2, 4, 5 tetracarbonate were synthesized for the first time with porous structure. This article presents the results of X-ray diffraction, elemental and IR analyzes of spectroscopic derivatographic complex compound of 1,2,4,5-bis benzene tetracarbonate of diiron (II). By means of the indicated physical-chemical analyzes the individual coordination form of carboxyl groups, chemical formula and unit cell parameters of the complex compound have been identified. Also the process of thermal degradation of the studied complex has been studied. It was revealed that the compound after losing six molecules of water is resistant until the temperature 300°С. In all likelihood coordinately related the water molecules form intermolecular hydrogen bonds both with oxygen of the carboxyl groups, and among themselves. In all likelihood coordinately related the water molecules form intermolecular hydrogen bonds both with oxygen of the carboxyl groups, and among themselves. Here molecules of coordination water in the different layers play an active role in this interaction. Thus, a two-dimensional structure of a complex compound by means of the hydrogen bonds is transformed into 3D structure.

description: Despite the noticeable progress in perceptual tasks like detection, instance segmentation and human parsing, computers still perform unsatisfactorily on visually understanding humans in crowded scenes, such as group behavior analysis, person re-identification and autonomous driving, etc. To this end, models need to comprehensively perceive the semantic information and the differences between instances in a multi-human image, which is recently defined as the multi-human parsing task. In this paper, we present a new large-scale database "Multi-Human Parsing (MHP)" for algorithm development and evaluation, and advances the state-of-the-art in understanding humans in crowded scenes. MHP contains 25,403 elaborately annotated images with 58 fine-grained semantic category labels, involving 2-26 persons per image and captured in real-world scenes from various viewpoints, poses, occlusion, interactions and background. We further propose a novel deep Nested Adversarial Network (NAN) model for multi-human parsing. NAN consists of three Generative Adversarial Network (GAN)-like sub-nets, respectively performing semantic saliency prediction, instance-agnostic parsing and instance-aware clustering. These sub-nets form a nested structure and are carefully designed to learn jointly in an end-to-end way. NAN consistently outperforms existing state-of-the-art solutions on our MHP and several other datasets, and serves as a strong baseline to drive the future research for multi-human parsing.
