SNe 2019vxm and 2020tlf: two luminous type II Supernovae with signatures of circumstellar interaction

AbstractWe present optical spectroscopic and photometric observations of type II SNe 2019vxm and 2020tlf. The photometric monitoring of SN 2019vxm continued for 592 days, two spectra were collected. SN 2020tlf was observed for 163 days and we obtained one spectra. The maximum luminosity of both SNe is high: mag for SN 2019vxm and SN 2020tlf, respectively. SN 2019vxm displays typical for most of SNe IIn photometric evolution: long rise to the maximum and slow brightness decline with several changes of the decline rate. The light curve of SN 2020tlf shows it may be considered as an intermediate object between classes II‐P and II‐L. The spectral evolution of SN 2019vxm was typical for SNe IIn, while for SN 2020tlf only weak signs of circumstellar interaction were observed at maximum light.

Visual Performance After Unilateral Implantation of an Extended Depth-of-Focus Intraocular Lens in Patients With Unilateral Cataract.

To investigate the visual performance after unilateral implantation of an extended depth-of-focus intraocular lens (IOL) in patients with unilateral cataracts. In this prospective study, uneventful phacoemulsification with LuxSmart IOL (Bausch & Lomb) implantation was performed in 25 eyes of 25 patients with unilateral cataracts. At postoperative 1, 4, 12, and 24 weeks, uncorrected and corrected visual acuity at far, intermediate, and near distances and the spherical equivalent in manifest refraction were measured. A Visual Function Index and modified Visual Function Index questionnaire were used to investigate glare, spectacle dependence, and satisfaction at 24 weeks in the eye that had surgery. At 6 months postoperatively, uncorrected distance visual acuity was 20/20 (0.0 logMAR) in 96% of cases, distance corrected intermediate visual acuity was 20/32 (0.2 logMAR) in all cases (60 cm), and distance corrected near visual acuity was 20/32 (0.2 logMAR) in 60% of cases (40 cm). The patient satisfaction score was 100% based on the Visual Function Index questionnaire for far and intermediate distance, respectively. No patients complained of the permanent photic phenomenon. No patients reported bilateral imbalance. All of the patients became spectacle independent for most of their intermediate activities at 60 cm. A total of 96% of the patients reported 100% contrast sensitivity in the Pelli-Robson test. The unilateral implantation of this EDOF IOL seems to be tolerated and effective in improving the visual function of patients with unilateral cataract with limited optical side effects such as halos or glare, providing spectacle-independent vision from far to intermediate object distances.

Transformer-based image generation from scene graphs

Graph-structured scene descriptions can be efficiently used in generative models to control the composition of the generated image. Previous approaches are based on the combination of graph convolutional networks and adversarial methods for layout prediction and image generation, respectively. In this work, we show how employing multi-head attention to encode the graph information, as well as using a transformer-based model in the latent space for image generation can improve the quality of the sampled data, without the need to employ adversarial models with the subsequent advantage in terms of training stability.The proposed approach, specifically, is entirely based on transformer architectures both for encoding scene graphs into intermediate object layouts and for decoding these layouts into images, passing through a lower dimensional space learned by a vector-quantized variational autoencoder. Our approach shows an improved image quality with respect to state-of-the-art methods as well as a higher degree of diversity among multiple generations from the same scene graph. We evaluate our approach on three public datasets: Visual Genome, COCO, and CLEVR. We achieve an Inception Score of 13.7 and 12.8, and an FID of 52.3 and 60.3, on COCO and Visual Genome, respectively. We perform ablation studies on our contributions to assess the impact of each component. Code is available at https://github.com/perceivelab/trf-sg2im.

A Dense-Aware Cross-splitNet for Object Detection and Recognition

Object detection and recognition is widely used in various fields and have become key technologies in computer vision. The distribution of objects in natural images can be roughly divided into densely stacked objects and scattered objects. Due to the incomplete attributes or features of some objects in densely stacked distributions, some object detectors have missed local area details or low detection accuracy. In this paper, we propose Cross-splitNet, a novel cross-split method for dense object detection and recognition based on candidate box generation. First, an adaptive feature extraction network is constructed. Different datasets are input into convolutional neural networks with various depths, the generalization of the model. Then, the proposed cross-split algorithm is introduced to guide the different deep networks to learn features of images with various densities, according to intermediate object density classification results. Finally, we adopt a feature pyramid network (FPN) subnet to perform multi-scale feature extraction while retaining lower-layer object information and physical characteristics. The model was trained on the COCO 17, VOC 12, and VOC 07 datasets, which contain a large number of object categories. Our network was compared with several two-stage detectors, and the results show that our model achieved an average precision ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">AP</i> ) of 0.819 at 22.9 frames per second ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FPS</i> ) on the VOC 07+12 dataset. The mean average precision ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">mAP</i> ) of the object detection model with R50+R2-101 backbones on the COCO dataset was increased by 1.9%.

NIR spectroscopic survey of protostellar jets in the star-forming region IC 1396N

Context. The bright-rimmed cloud IC 1396N, associated with an intermediate-mass star-forming region, hosts a number of CO, molecular hydrogen, and Herbig-Haro (HHs) outflows powered by a set of millimetre compact sources. Aims. The aim of this work is to characterise the kinematics and physical conditions of the H2 emission features spread throughout the IC 1396N region. The features appear as chains of knots with a jet-like morphology and trace different H2 outflows. We also obtain further information about (and an identification of) the driving sources. Methods. Low-resolution, long-slit near-infrared spectra were acquired with the NICS camera at the TNG telescope, using grisms KB (R ~ 1200), HK, and JH (R ~ 500). Several slit pointings and position angles were used throughout the IC 1396N region in order to sample a number of the H2 knots that were previously detected in deep H2 2.12 μm images. Results. The knots exhibit rich ro–vibrational spectra of H2, consistent with shock-excited excitation, from which radial velocities and relevant physical conditions of the IC 1396N H2 outflows were derived. These also allowed estimating extinction ranges towards several features. [Fe ii] emission was only detected towards a few knots that also display unusually high H2 1–0 S(3)/S(1) flux ratios. The obtained radial velocities confirm that most of the outflows are close to the plane of the sky. Nearby knots in the same chain often display different radial velocities, both blue–shifted and red–shifted, which we interpret as due to ubiquitous jet precession in the driving sources or the development of oblique shocks. One of the chains (strand A, i.e. knots A1 to A15) appears as a set of features trailing a leading bow-shock structure consistent with the results of 3D magneto-hydrodynamical models. The sides of the leading bow shock (A15) exhibit different radial velocities. We discuss possible explanations. Our data cannot confirm whether strands A and B have both originated in the intermediate mass young stellar object [BGE2002] BIMA 2 because a simple model of a precessing jet cannot account for their locations. Conclusions. Near-infrared spectroscopy has confirmed that most of the H2 ro-vibrational emission in IC 1396N is shock-excited rather than uv-excited in photon-dominated regions. It has shown a complex kinematical structure in most strands of emitting knots as well.

PECULIARITIES OF APPLYING ART THERAPY IN WORK WITH CHILDREN

The article is devoted to the coverage of the peculiarities of the application of art therapy in working with children, in particular, the disclosure of the characteristics of child development and consideration of the main art-therapeutic directions in working with children. The study of foreign and domestic literature on the study showed that art therapy is widely used in working with children, namely in psychodiagnostic, psychocorrectional and psychotherapeutic work, as it is the mildest method of working with various psychological problems and promotes creative development of cognitive and creative abilities of the child. establishing harmonious relations with the environment. Childhood is an important period of a child's development, during this period the child's cognitive mental processes and creative activity begin to develop rapidly, this is manifested in artistic creativity and constructive games. Summarizing the practical experience of psychologists working with children, it can be noted that among the variety of areas of art therapy in working with children are widely used: isotherapy, fairy tale therapy, puppet therapy and sand therapy. It was found that isotherapy - therapy with fine arts, namely drawing, is used in the process of psychological correction in working with children to harmonize the emotional state of the child, the development of interpersonal skills, the disclosure of creative abilities of the child. Drawing is an effective tool, because thanks to it the child can freely express their thoughts, feelings and experiences through the language of images, symbols and colors, as well as get rid of negative experiences and express their attitude to the surrounding reality. An effective way of psychological work with children is fairy tale therapy, namely fairy tale therapy, which uses a metaphor to create connections between fairy tale events and behavior in real life, as well as the process of transferring fairy tale meanings into reality. It should be noted that fairy tale therapy is used for therapeutic purposes, helps the child to actualize and realize his problems and see ways to solve them, promotes the development of imagination and creative thinking of the child. A fairy tale for a child is a special reality that allows you to expand the boundaries of ordinary life, to meet with complex phenomena and feelings in a form understandable to the child. Fairy tales teach children moral principles, norms of behavior, show the true values ​​of life. Puppet therapy is a therapeutic direction that uses as a main method of corrective action a doll, which is an intermediate object in the interaction of a child and an adult. In turn, puppet therapy as a method is based on the processes of identifying a child with a favorite cartoon character, fairy tale and favorite toy. The child, knowing the real world, its social connections and relationships, actively projects the perceived experience into a specific game situation. The main object of such a social projection for a long time are dolls. In puppet therapy different variants of dolls are used: puppet dolls, finger dolls, shadow dolls, rope dolls, plane dolls, glove dolls. Puppet therapy promotes the development of cognitive processes and improves children's social adaptation and communication skills. At the same time, sand therapy is a type of therapy associated with the use of natural materials, namely sand for psychotherapeutic purposes. Sand therapy is widely used in correctional, developmental and educational work with children. Sand games are one of the forms of a child's natural activity, interacting with which the child's creative abilities, imagination, spontaneity and originality of the child's worldview develop. In the course of sand therapy, a free and protected space is created, where the child can explore his own inner world, turning his own experiences and experiences into images that he understands. In addition, sand therapy helps to harmonize the inner state of the child and improve his social skills. Therefore, the use of art therapy is an effective way to work with children, which contributes to the comprehensive development and self-expression of the child.

Perturbative calculations of entanglement entropy

This paper is an attempt to extend the recent understanding of the Page curve for evaporating black holes to more general systems coupled to a heat bath. Although calculating the von Neumann entropy by the replica trick is usually a challenge, we have identified two solvable cases. For the initial section of the Page curve, we sum up the perturbation series in the system-bath coupling κ; the most interesting contribution is of order 2s, where s is the number of replicas. For the saturated regime, we consider the effect of an external impulse on the entropy at a later time and relate it to OTOCs. A significant simplification occurs in the maximal chaos case such that the effect may be interpreted in terms of an intermediate object, analogous to the branching surface of a replica wormhole.

Many-body near-field radiative heat pumping

We introduce a local radiative heat-pumping effect between two bodies in a many-body system, obtained by periodically modulating both the temperature and the position of an intermediate object using an external source of energy. We show that the magnitude and the sign of energy flow can be tuned by changing the oscillation amplitude and dephasing of the two parameters. This many-body effect paves the way for an efficient and active control of heat fluxes at the nanoscale.

On the Sweep Map for $\vec{k}$-Dyck Paths

Garsia and Xin gave a linear algorithm for inverting the sweep map for Fuss rational Dyck paths in $D_{m,n}$ where $m=kn\pm 1$. They introduced an intermediate family $\mathcal{T}_n^k$ of certain standard Young tableaux. Then inverting the sweep map is done by a simple walking algorithm on a $T\in \mathcal{T}_n^k$. We find their idea naturally extends for $\mathbf{k}^\pm$-Dyck paths, and also for $\mathbf{k}$-Dyck paths (reducing to $k$-Dyck paths for the equal parameter case). The intermediate object becomes a similar type of tableau in $\mathcal{T}_\mathbf{k}$ of different column lengths. This approach is independent of the Thomas-Williams algorithm for inverting the general modular sweep map.

Object affordance detection with relationship-aware network

Object affordance detection, which aims to understand functional attributes of objects, is of great significance for an autonomous robot to achieve a humanoid object manipulation. In this paper, we propose a novel relationship-aware convolutional neural network, which takes the symbiotic relationship between multiple affordances and the combinational relationship between the affordance and objectness into consideration, to predict the most probable affordance label for each pixel in the object. Different from the existing CNN-based methods that rely on separate and intermediate object detection step, our proposed network directly produces the pixel-wise affordance maps from an input image in an end-to-end manner. Specifically, there are three key components in our proposed network: Coord-ASPP module introducing CoordConv in atrous spatial pyramid pooling (ASPP) to refine the feature maps, relationship-aware module linking the affordances and corresponding objects to explore the relationships, and online sequential extreme learning machine auxiliary attention module focusing on individual affordances further to assist relationship-aware module. The experimental results on two public datasets have shown the merits of each module and demonstrated the superiority of our relationship-aware network against the state of the arts.

Regrasp Planning Using Stable Object Poses Supported by Complex Structures

Using regrasp planning, a robot could pick up an object, place it down to an intermediate stable state, and reorient the object into certain poses by grasping and picking it up again. Regrasp is an important skill when a robot cannot reorient the object directly with one grasp due to kinematic constraints and collisions. It uses intermediate object states to release, regrasp, and reorient objects. In our previous work, we developed regrasp algorithms considering intermediate stable states on simple fixtures like a flat table surface. This paper further develops our previous studies by enabling regrasp planning using stable object poses on complex structures. The complex structures have high variety of contact elements. They not only provide flat surface supports but also point supports, line supports, and a combination of them. In detail, the developed regrasp planner includes two parallel processes. One is a dynamic simulator that computes immediate stable poses on given supporting structures. The other builds a regrasp graph using the stable states and finds a sequence of reorient motion by searching the graph. We performed thousands of simulation and real-world verification to analyze the performance of the developed planner. We conclude that our planner has higher performance on regrasping than the previous ones. The number of candidate regrasp sequences increased and the lengths became shorter. We also compared simulation results with real-world executions, and gave suggestions on the selection of supporting structures considering real-world implementations.

Right-angled Coxeter quandles and polyhedral products

To a Coxeter group W W one associates a quandle X W X_W from which one constructs a group A d ( X W ) \mathrm {Ad}(X_W) . This group turns out to be an intermediate object between W W and the associated Artin group. By using a result of Akita, we prove that A d ( X W ) \mathrm {Ad}(X_W) is given by a pullback involving W W , and by using this pullback, we show that the classifying space of A d ( X W ) \mathrm {Ad}(X_W) is given by a space called a polyhedral product whenever W W is right-angled. Two applications of this description of the classifying space are given.

Lusztig data of Kashiwara–Nakashima tableaux in types B and C

We provide an explicit combinatorial description of the embedding of the crystal of Kashiwara–Nakashima tableaux in types B and C into that of i-Lusztig data associated to a family of reduced expressions i of the longest element w0. The description of the embedding is simple and elementary using only the Schützenberger's jeu de taquin and RSK algorithm. A spinor model for classical crystals plays an important role as an intermediate object connecting Kashiwara–Nakashima tableaux and Lusztig data.

Newton–Okounkov Bodies over Discrete Valuation Rings and Linear Systems on Graphs

AbstractThe theory of Newton–Okounkov bodies attaches a convex body to a line bundle on a variety equipped with a flag of subvarieties. This convex body encodes the asymptotic properties of sections of powers of the line bundle. In this article, we study Newton–Okounkov bodies for schemes defined over discrete valuation rings. We give the basic properties and then focus on the case of toric schemes and semistable curves. We provide a description of the Newton–Okounkov bodies for semistable curves in terms of the Baker–Norine theory of linear systems on graphs, finding a connection with tropical geometry. We do this by introducing an intermediate object, the Newton–Okounkov linear system of a divisor on a curve. We prove that it is equal to the set of effective elements of the real Baker–Norine linear system of the specialization of that divisor on the dual graph of the curve. As a bonus, we obtain an asymptotic algebraic geometric description of the Baker–Norine linear system.

O mito da cadeira vazia

The post-Morenian development of a theory of imagination and fantasy requires us to revise the concept of supplementary reality, understood today in its historical conception as a key aspect of the theory of psychodrama, that forces us to review in the light of a set that comprises the Moreno’s philosophy of the moment, adhered closely to its theoretical formulations and to the practical and technical consequences. From this point of view, the technique of the empty chair, made mythical, is much more than a technique, gaining more importance when it exceeds its mere definition as an intermediate object, focused today on the roots of a supplementary reality, that is, the field of action of our creativity in the psychodramatic scene and in the relational daily life of all of us.

Simulation of train–bridge interaction under wind loads: a rigid-flexible coupling approach

ABSTRACTThis study proposed a rigid-flexible coupling method to simulate the train–bridge vibration under the actions of wind loads. Specifically, the numerical models of a rigid train and a flexible bridge were first established in the Multibody Dynamics Software SIMPACK and the Finite Element Software ANSYS, respectively. The bridge model was then integrated, using the virtual rigid body as an intermediate object, into the SIMPACK as a flexible body through the interface module FlexModal. The wind loads were applied to the coupled train–bridge system in the SIMPACK, and then the dynamic responses were obtained. The accuracy and efficiency of the proposed rigid-flexible coupling approach was verified by calculating the responses of the train–bridge system under various train speeds and comparing the results with those from FlexTrack module. The Xijiang Bridge on the Nanning–Guangzhou railway was employed as a case study to evaluate the dynamic indices under various combinations of the train and wind speeds.

Sparse Rig Parameter Optimization for Character Animation

We propose a novel motion retargeting method that efficiently estimates artist-friendly rig space parameters. Inspired by the workflow typically observed in keyframe animation, our approach transfers a source motion into a production friendly character rig by optimizing the rig space parameters while balancing the considerations of fidelity to the source motion and the ease of subsequent editing. We propose the use of an intermediate object to transfer both the skeletal motion and the mesh deformation. The target rig-space parameters are then optimized to minimize the error between the motion of an intermediate object and the target character. The optimization uses a set of artist defined weights to modulate the effect of the different rig space parameters over time. Sparsity inducing regularizers and keyframe extraction streamline any additional editing processes. The results obtained with different types of character rigs demonstrate the versatility of our method and its effectiveness in simplifying any necessary manual editing within the production pipeline.

Artificial islands as a manifestation of glocalisation

The article is devoted to economic reasons for creation of artificial lands, including artificial islands, and problems related to their functioning. The scientific achievements of economic geography constitute a theoretical basis of the analysis. Economic reasons for constructing artificial islands in particular may, to a large extent, be explained by reference to a new economic geography of Paul Krugman. Therefore, the Authors associate the dynamically developing phenomenon of building artificial islands with the process of glocalisation. On the other hand, functioning of artificial islands – in their opinion – may basically be reduced to a concept of the balance of a company, as an artificial island may be treated as its counterpart.

Integration of location-based information into mobile learning management system to verify scientific formulas in informal learning environment

Scientific formulas govern our life while moving from one location to another. Hence, this study investigates into the development of an adaptive mobile learning model that extends traditional learning systems that address content customisation issue, to include formulas verification feature with help of location-based information in informal learning environment. The main contribution of this novel model is to provide the mobile learner with a virtual-teacher anytime-anywhere to verify or even solve course-related tasks, especially in scientific courses such as math or physics formulas. The virtual-teacher is addressed in this study in the form of intermediate object. This object is built by merging data from three different resources: mobile learner profile, formulas profile, and location-based information. As a result, mobile learner will receive the location-aware personalised outcomes in form of answers that correspond to the pre-defined tasks. The instructors can also benefit from this adaptive model to demonstrate their lessons-related formulas, outside classrooms.
