Panoptic-Level Image-to-Image Translation for Object Recognition and Visual Odometry Enhancement

Image-to-image translation methods have progressed from only considering the image-level information to integrating the global- and instance-level information. However, only the foreground instances are refined, and the background semantics are taken as an entire feature, which causes a substantial loss of the semantic information in the translation. Additionally, the insufficient quality of the translated semantic regions also leads to an unsatisfactory performance of the object recognition or visual odometry tasks in which the translated images/videos are further used. In this paper, we propose a novel generative adversarial network for panoptic-level image-to-image translation (PanopticGAN). The proposed method has three advantages: 1) the extracted panoptic perception (i.e., the foreground instances and background semantic regions) as content codes are aligned with the sampled panoptic style codes, which considers the panoptic-level information to avoid the semantic information loss, and the latent space of each object has a rich fusion of content and style codes to generate the higher-fidelity results; 2) a feature masking module is proposed to extract the representations within each object contour by masks for sharpening the object boundaries; 3) the improved fidelity of the translated semantic regions further contributes to enhancing the performance of the object recognition or visual odometry tasks that the translated images/videos are used in. In this paper, we also annotate a compact panoptic segmentation dataset for the thermal-to-color translation task. Extensive experiments are conducted to demonstrate the effectiveness of our PanopticGAN over the latest methods.
AN ANALYSIS OF CULTURAL MEANING RELATED TO LEXICONS IN SATYENG BERATI DANCE

AbstractSatyeng Berati dance is a traditional dance from Bali with many lexicons to identify and document. But over time, several lexicons are rarely used when doing dance practice. It has the possibility of language extinction because the number of speakers of that language has decreased. The purpose of this study is to document the lexicons in the Satyeng Berati dance, especially the cultural meanings of the lexicons in movement. This study is designed in the form of descriptive qualitative research. Data collection is done through observation and interviews. Based on the results of the study, it was found that there were thirty-one lexicons in the Satyeng Berati dance movements. The lexicons are divided into six, namely, the lexicon on eye movements (four lexicons), neck movements (one lexicon), body movements (twelve lexicons), hand movements (seven lexicons), finger movements (two lexicons), and foot movements (five lexicons). The thirty-one movements are nyeledet kanan, nyeledet kiri, ngelier kanan, ngelier kiri, ngegenjet leher, ngelung bulan kanan, ngelung bulan kiri, ngotag pala, ngeseh, ngelo, sleag-sleog kanan, sleag-sleog kiri, agem kanan, agem kiri, ngegol kanan, ngegol kiri, teisik, nagastru, luk nerudut, nabdab petitis, mentang laras, nyalud, ngukel, luk ngelimat, jeriring, ulap-ulap, gandang arep, milpil, nyeregseg kanan, nyeregseg kiri, and ngelikas. These lexicons have their cultural meaning, which is certainly different from other traditional dances. The documentation activity on the lexicon in the Satyeng Berati dance is one of the efforts to preserve the local language to avoid language death.Keywords: Lexicons, cultural meaning, movements, Satyeng Berati dance
Buckling of nonuniform carbon nanotubes under concentrated and distributed axial loads

Abstract. Buckling of nonuniform carbon nanotubes are studied with the axial load taken as a combination of concentrated and axially distributed loads. Constitutive modelling of the nanotubes is implemented via nonlocal continuum mechanics. Problem solutions are obtained by employing a weak formulation of the problem and the Rayleigh-Ritz method which is implemented by using orthogonal Chebyshev polynomials. The accuracy of the method of solution is verified against available results. Solutions are obtained for the cases of uniformly distributed and triangularly distributed axial loads. Contour plots are given to assess the effect of nonuniform cross-sections and the small-scale parameter on the buckling load for a combination of simply supported, clamped and free boundary conditions.
The unquenchable quest for beauty

In this beauty-crazed superficial world where surgically enhanced and digitally airbrushed media images have become an unquestioned standard, millions of men and women are selecting surgical treatments to enhance, minimize, nip and tuck just about every inch of the body. But when cosmetic procedures are met with little satisfaction, and fuel the desire for more surgical enhancements an underlying psychological cause may be to blame. This paper aims to understand the surge in the requests for cosmetic surgery by evaluating whether there is any connection between body dysmorphic disorder and addiction to cosmetic surgery

Analysis of Stability on Single-leg Standing by Wearing a Head Mounted Display

Objective: The purpose of this study was to investigate the effects of three visual conditions (eyes opened, eyes closed, and wearing of a head mounted display [HMD]) on single-leg standing through kinematics and kinetic analysis. Method: Twelve college students (age: 24.5 ± 2.6 years, height: 175.0 ± 6.4 cm, weight: 69.2 ± 5.1 kg) participated in this study. The study method adopted three-dimensional analysis with six cameras and ground reaction force measurement with one force plate. The analysis variables were coefficient of variation (CV) of the center of body mass, head movement, ground reaction force, and center of pressure, which were analyzed using one-way analysis of variance with repeated measures according to visual conditions. Results: In most cases, the results of this study showed that the CV was significantly higher in the order of HMD wearing, eyes closed, and eyes opened conditions. Conclusion: Our results indicated that body sway was the largest in the HMD wearing condition, and the risk of falling was high owing to the low stability.
Chronic symptoms in patients with unilateral vestibular hypofunction: systematic review and meta-analysis

Objective To systematically evaluate the full spectrum of self-reported chronic symptoms in patients with unilateral vestibular hypofunction (UVH) and to investigate the effect of interventions on these symptoms. Methods A systematic review was conducted following the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis Statement (PRISMA). A literature search was performed in Pubmed, Web of Science, Embase, and Scopus to investigate self-reported symptoms and self-report questionnaires in patients with UVH. All original studies ranging from full-text clinical trials to case reports, written in English, German, and French, were included. The frequency of self-reported symptoms was presented. For self-report questionnaires, a meta-analysis was carried out to synthesize scale means by the pre- and post-intervention means and mean changes for studies that investigated interventions. Results A total of 2,110 studies were retrieved. Forty-seven studies were included after title-abstract selection and full-text selection by two independent reviewers. The symptoms of UVH patients included chronic dizziness (98%), imbalance (81%), symptoms worsened by head movements (75%), visually induced dizziness (61%), symptoms worsened in darkness (51%), and oscillopsia (22%). Additionally, UVH could be accompanied by recurrent vertigo (77%), tiredness (68%), cognitive symptoms (58%), and autonomic symptoms (46%). Regarding self-report questionnaires, UVH resulted on average in a moderate handicap, with an estimated mean total score on the Dizziness Handicap Inventory (DHI) and the Vertigo Symptom Scale (VSS) of 46.31 (95% CI: 41.17–51.44) and 15.50 (95% CI: 12.59–18.41), respectively. In studies that investigated the effect of vestibular intervention, a significant decrease in the estimated mean total DHI scores from 51.79 (95% CI: 46.61–56.97) (pre-intervention) to 27.39 (95% CI: 23.16–31.62) (post intervention) was found (p < 0.0001). In three studies, the estimated mean total Visual Analog Scale (VAS) scores were 7.05 (95% CI, 5.64–8.46) (pre-intervention) and 2.56 (95% CI, 1.15–3.97) (post-intervention). Finally, a subgroup of patients (≥32%) persists with at least a moderate handicap, despite vestibular rehabilitation. Conclusion A spectrum of symptoms is associated with UVH, of which chronic dizziness and imbalance are most frequently reported. However, semi-structured interviews should be conducted to define the whole spectrum of UVH symptoms more precisely, in order to establish a validated patient-reported outcome measure (PROM) for UVH patients. Furthermore, vestibular interventions can significantly decrease self-reported handicap, although this is insufficient for a subgroup of patients. It could therefore be considered for this subgroup of patients to explore new intervention strategies like vibrotactile feedback or the vestibular implant.

Towards Onsite Age Estimation of Semen Stains Using Fluorescence Spectroscopy

The age estimation of biological traces is one of the holy grails in forensic investigations. We developed a method for the age estimation of semen stains using fluorescence spectroscopy in conjunction with a stoichiometric ageing model. The model describes the degradation and generation rate of proteins and fluorescent oxidation products (FOX) over time. The previously used fluorimeter is a large benchtop device and requires system optimization for forensic applications. In situ applications have the advantage that measurements can be performed directly at the crime scene, without additional sampling or storage steps. Therefore, a portable fiber-based fluorimeter was developed, consisting of two optimized light-emitting diodes (LEDs) and two spectrometers to allow the fluorescence protein and FOX measurements. The handheld fiber can be used without touching the traces, avoiding the destruction or contamination of the trace. In this study, we have measured the ageing kinetics of semen stains over time using both our portable fluorimeter and a laboratory benchtop fluorimeter and compared their accuracies for the age estimation of semen stains. Successful age estimation was possible up to 11 days, with a mean absolute error of 1.0 days and 0.9 days for the portable and the benchtop fluorimeters, respectively. These results demonstrate the potential of using the portable fluorimeter for in situ applications.
Non-existence of global solutions to nonlinear wave equations with positive initial energy

We consider the Cauchy problem for nonlinear abstract wave equations in a Hilbert space. Our main goal is to show that this problem has solutions with arbitrary positive initial energy that blow up in a finite time. The main theorem is proved by employing a result on growth of solutions of abstract nonlinear wave equation and the concavity method. A number of examples of nonlinear wave equations are given. A result on blow up of solutions with arbitrary positive initial energy to the initial boundary value problem for the wave equation under nonlinear boundary conditions is also obtained.
Analogous seasonal evolution of the South Atlantic SST dipole indices

Two variants of sea‐surface temperature (SST) dipole indices for the South Atlantic Ocean (SAO) has been previously described representing: (1) the South Atlantic subtropical dipole (SASD) supposedly peaking in austral summer and (2) the SAO dipole (SAOD) in winter. In this study, we present the analysis of observational data sets (1985–2014) showing the SASD and SAOD as largely constituting the same mode of ocean–atmosphere interaction reminiscent of the SAOD structure peaking in winter. Indeed, winter is the only season in which the inverse correlation between the northern and southern poles of both indices is statistically significant. The observed SASD and SAOD indices exhibit robust correlations (P ≤ 0.001) in all seasons and these are reproduced by 54 of the 63 different models of the Coupled Models Intercomparison Project analysed. Their robust correlations notwithstanding the SASD and SAOD indices appear to better capture different aspects of SAO climate variability and teleconnections.
Unpacking Name-Based Race Discrimination

IZA DP No. 16254 JUNE 2023 Unpacking Name-Based Race Discrimination* We investigate the extent and underlying mechanisms of how race beliefs associated with applicants’ names affect hiring decisions. Using nationally representative data, we find widespread beliefs that people with names perceived to be Black possess lower levels of education, productivity and noncognitive skills. Notably, this race penalty persists when considering only variation in race perception for the same name and when omitting distinctly Black names. Conducting an incentivized hiring experiment with real worker data, we find that participants are 30 percentage points (pp) more likely to hire workers perceived to be white compared to Black. Controlling for productivity and noncognitive skills beliefs reduces this racial gap to 21 pp and 20 pp, respectively. Results indicate that race serves as a decision heuristic as employers make faster decisions and display more certainty when perceived race differences between candidates are large. Moreover, the race gap in hiring increases by 25% when employers are forced to make quick decisions. Estimates from a structural drift-diffusion model quantify the effect of beliefs and show that employers differ both in their usage of racial heuristics and inclination to override these heuristics when given sufficient decision time.

A Numerical Approach to Possible Identification of the Noisiest Zones of a Wall Surface with a Flow Interaction

This paper examines the use of proper orthogonal decomposition (POD) and singular value decomposition (SVD) to identify zones on the surface of the source that contribute the most to the sound power the source radiates. First, computational fluid dynamics (CFD) is used to obtain the pressure field at the surface of the blade in a subsonic regime. Then the fluctuation of this pressure field is used as the input for the loading noise in the Ffowcs Williams and Hawkings (FW&H) acoustic analogy. The FW&H analogy is used to calculate the sound power that is radiated by the blade. Secondly, the most important acoustic modes of POD and SVD are used to reconstruct the radiated sound power. The results obtained through POD and SVD are similar to the acoustic power directly obtained with the FW&H analogy. It was observed that the importance of the modes to the radiated sound power is not necessarily in ascending order (for the studied case, the seventh mode was the main contributor). Finally, maps of the most contributing POD and SVD modes have been produced. These maps show the zones on the surface of the blade, where the dipolar aeroacoustic sources contribute the most to the radiated sound power. These identifications are expected to be used as a guide to design and shape the blade surface in order to reduce its radiated noise.
The self-similarity of wall-bounded temporally accelerating turbulent flows

ABSTRACT From the study of viscous flow it is known that certain time-dependent laminar problems, such as the impulsively started flat plate and the diffusion of a vortex sheet, possess self-similar solutions. Previous studies of turbulent channel and pipe flows accelerating between two steady states have shown that the flow field evolves in three distinct stages. Furthermore, recent direct numerical simulations have shown that the perturbation velocity, i.e. the surplus velocity from the initial value, in an impulsively accelerating turbulent channel and pipe flow also possesses a self-similar distribution during the initial stage. In here, these results are developed analytically and it is shown that accelerating flows in which the centreline velocity develops as U∧c(t) = U0(t/t0)m will possess a self-similar velocity distribution during the initial stage. The displacement thickness of the perturbation velocity is shown to be dependent only on the type of acceleration, and not on the initial Reynolds number, the acceleration rate or the change in Reynolds number. The derived formulas are verified with good agreement against measurements performed in a linearly accelerating turbulent pipe flow and with data from channel flow simulations.
Description of Junior High School Students’ Mathematical Understanding According to Skemp Theory in terms of Rational Personality Types

Mathematical understanding is one of the supporting factors for students' success in mathematics. Skemp divides understanding into two types, namely instrumental understanding and relational understanding. This research purpose was to describe the mathematical understanding of seventh grade D students in solving set problems based on Skemp's theory of understanding in terms of rational personality types. The type of research used was descriptive qualitative. This research was conducted at Junior High School Darul Aman Mataram of 2021/2022 academic year. Selection of subjects using a purposive sampling technique. The subjects in this study were two students with rational personality types. Data were obtained using a mathematical understanding test and interviews. The study's results showed that students with rational personality types tend to have a relational understanding because they can explain reasons or interpret problem-solving procedures according to the set concept correctly. In addition, students are able to understand the purpose of the given set of problems, can apply ideas according to the logic of thinking in solving problems, can write problem solving procedures coherently according to Skemp's theory even though they tend to be brief, can solve mathematical understanding problems accompanied by appropriate answer arguments, can change mathematical sentences in the given problem in the form of words, images, or certain mathematical symbols. Furthermore, this type can achieve all of the indicators of instrumental understanding and can fulfill the six indicators of relational understanding, except for the ability to correlate several set concepts. Based on these results, it is expected that rational personality type students can determine detailed planning in solving problems, and improve understanding of mathematical concepts such as being more careful in the use of solution strategies so that students are accustomed to applying various solution strategies.
