A social-cognitive research on metaphor and metonymy: Taking age appellations in Chinese as an example

The process from individual language to communal language, from individual experience to communal embodiment, and from individual cognition to collective cognition is based on human embodiment and social interactions. Metaphor and metonymy are two basic cognitive approaches to the world. Thus, human cognition is metaphorical and metonymic in essence, and metaphonymy is embodied and social in nature. In the perspective of social embodied cognition, this paper, taking social metaphonymy as a theoretical foundation and the Chinese age appellations as the corpus, demonstrates that Chinese age appellation has eight metaphonymic categories, namely, physiology, gender, wisdom, accessories, raising, behavior, animal and plant, and number. The paper, by expounding the embodiment and metaphonymy, aims to reveal metaphonymic cognitive mechanism of Chinese age appellations.

Effect of Single and Dual Modifications on Properties of Lotus Rhizome Starch Modified by Microwave and γ-Irradiation: A Comparative Study

A comparative study between two novel starch modification technologies, i.e., microwave (MI) and γ-irradiation (IR), is of important significance for their applications. The objective of this work is to compare the changes in lotus rhizome starch (LRS) subjected to single modifications by MI (thermal treatment) and IR (non-thermal treatment), and dual modification by changing the treatment sequence, i.e., microwave followed by irradiation (MI-IR) and irradiation followed by microwave (IR-MI). The amylose content of native and modified LRS varied from 14.68 to 18.94%, the highest and lowest values found for native and MI-LRS, respectively. IR-treated LRS showed the lowest swelling power (4.13 g/g) but highest solubility (86.9%) among native and modified LRS. An increase in light transmittance value suggested a lower retrogradation rate for dual-modified starches, making them more suitable for food application at refrigeration and frozen temperatures. Dual-modified LRS showed the development of fissures and dents on the surface of granules as well as the reduction in peak intensities of OH and CH2 groups in FTIR spectra. Combined modifications (MI and IR) reduced values of pasting parameters and gelatinization properties compared to native and microwaved LRS and showed improved stability to shear thinning during cooking and thermal processing. The sequence of modification also affected the rheological properties; the G′ and G″ of MI-IR LRS were lower (357.41 Pa and 50.16 Pa, respectively) than the IR-MI sample (511.96 Pa and 70.09 Pa, respectively), giving it a soft gel texture. Nevertheless, dual modification of LRS by combining MI and IR made more significant changes in starch characteristics than single modifications.

Exact elasticity solution for natural frequencies of functionally graded simply-supported structures

This paper gives an exact three-dimensional elastic model for the free vibration analysis of functionally graded one-layered and sandwich simply-supported plates and shells. An exact elasticity solution is proposed for the differential equations of equilibrium written in general orthogonal curvilinear coordinates. The equations consider a geometry for shells without simplifications, and allow the analysis of the cases of spherical shell panels, cylindrical shell panels, cylindrical closed shells and plates. The main novelty is the possibility of a general formulation for these geometries. The coefficients in equilibrium equations depend on the thickness coordinate because of the radii of curvature for the shell geometries and/or the use of functionally graded layers. These equations are solved in a layer-wise form by introducing a number of mathematical layers where the coefficients are constant. An exhaustive 3D overview of the vibration modes is given for a number of thickness ratios, imposed wave numbers, geometries and embedded materials. Results are given for one-layered functionally graded plates and shells and for sandwich structures with external homogenous skins and an internal core made of functionally graded material. These results can also be used as reference solutions for the validation of analytical or numerical two-dimensional models for functionally graded plates and shells.
Tracking de múltiples objetos aplicado a insectos

La detección y el tracking de objetos múltiples es un aspecto muy estudiado dentro de las ciencias de las imágenes. El tracking de objetos múltiples es, en general, un problema exigente debido a una amplia gama de potenciales problemas que pueden surgir (como el movimiento brusco de los objetos, el cambio en apariencia de los objetos o la escena de fondo, frames de mala calidad, oclusión entre objetos o entre el objeto y la escena, o movimiento de la cámara). Usualmente, el tracking es realizado en aplicaciones que requieren la locación de los objetos en cada frame para realizar algún posterior procesamiento. Conociendo la complejidad del problema de tracking, normalmente se asumen determinadas condiciones que hacen que la resolución sea más sencilla en el contexto particular. En este trabajo, describimos los métodos y técnicas utilizados para realizar una aplicación que detecta y trackea múltiples objetos (en particular, insectos en placas de Petri en videos obtenidos en un proyecto de integración con el Laboratorio de Zooloǵıa de Invertebrados II, del Departamento de Bioloǵıa, Bioqúımica y Farmacia), y analiza distintos aspectos del recorrido efectuado por cada uno de ellos. El objetivo general y a largo plazo del proyecto es desarrollar una aplicación que permita realizar identificación y tracking de objetos genéricos.

Single-Cell Analyses of Heterotopic Ossification: Characteristics of Injury-Related Senescent Fibroblasts

Introduction Injury-related cellular senescence may be involved in heterotopic ossification, and no research has been performed about this before. Methods and Results The study utilized integrated single-cell RNA-sequencing (scRNA-seq) data from heterotopic ossification samples. The number of senescent cells increased from day 3 and reached the highest level at day 21. However, the expression level of Cyclin Dependent Kinase Inhibitor 2A (Cdkn2a) has no such tendency as the change of cell amount, indicating that the expression level of Cdkn2a may be different in different types of senescent cells or the same time of senescent cell at different time points. The expression level of SASPs (senescence associated secret phenotypes) was also different in different types of senescent cells or at different time points. The GO (gene ontology) analysis revealed that the senescent cells were significantly correlated with the ossification processes, like ECM organization, cell adhesion, ossification, cartilage development, etc. Trajectory analysis showed that injury-related senescent fibroblasts (day 7 and 21) and age-related senescent fibroblasts (day 0 and 42) were in different branches. GO analysis demonstrated that injury-related senescent fibroblasts were mainly related to ossification and ECM remodeling. The KEGG (Kyoto Encyclopedia of Genes and Genomes) results revealed that the ossification was significantly corrected with protein processing in PI3K-Akt signaling, MAPK signaling, focal adhesion, etc. Conclusion Consequently, we demonstrated that, unlike age-related senescence, the injury-related senescence demonstrated significantly different SASP phenotypes. The injury-related senescence of fibroblasts is associated with heterotopic ossification formation and may act through PI3K/Akt-induced SASPs.
Exploring children’s TikTok cultures in India: Negotiating access, uses, and experiences under restrictive parental mediation

TikTok is a popular platform allowing users to view and make short videos. The platform's embeddedness among youth cultures is key to TikTok’s commercial success, to attract and sustain a diverse array of international users. The discourse around children and social media especially TikTok is laced with technopanics, as is the case in India. Although sparse, literature shows children in India want to explore social media but parental mediation usually follows a restrictive style. Using a qualitative approach and multimodal methods, we unpack how children (10–18 years) in a large Indian metropolitan city use TikTok for self-presentation and creative expression while navigating restrictive parental mediation. This article helps gain in-depth understanding of children’s TikTok cultures in India by foregrounding their voices and contributes to larger scholarship on youth digital cultures by focusing on their: (a) vernacular cultures on TikTok, (b) deliberations on safety and wellbeing, and (c) negotiations regarding agency and resistance.
A Note on Erdős-Szekeres Theorem

Erdős-Szekeres Theorem is proven. The proof is very similar to the original given by Erdős and Szekeres. However, it explicitly uses properties of binary trees to prove and visualize the existence of a monotonic subsequence. It is hoped that this presentation is helpful for pedagogical purposes.
Underdetermined DOA estimation and blind separation of non-disjoint sources in time-frequency domain based on sparse representation method

This paper deals with the blind separation of nonstationary sources and directionofarrival(DOA) estimation in the underdetermined case, when there are more sources than sensors. We assume the sources to be timefrequency(TF) disjoint to a certain extent. In particular, the number of sources presented at any TF neighborhood is strictly less than that of sensors. We can identify the real number of active sources and achieve separation in any TF neighborhood by the sparse representation method. Compared with the subspacebased algorithm under the same sparseness assumption, which suffers from the extra noise effect since it cannot estimate the true number of active sources, the proposed algorithm can estimate the number of active sources and their corresponding TF values in any TF neighborhood simultaneously. Another contribution of this paper is a new estimation procedure for the DOA of sources in the underdetermined case, which combines the TF sparseness of sources and the clustering technique. Simulation results demonstrate the validity and high performance of the proposed algorithm in both blind source separation(BSS) and DOA estimation.

Implicit Gender Bias in the Classroom: Memories from K-12 Implicit Gender Bias in the Classroom: Memories from K-12 Education Education

Implicit biases affect everyone in society, including within the K-12 education system. This study investigated what memories of implicit gender bias preservice teachers (PSTs) recalled from their K-12 education. These memories may be connected to the PSTs’ embedded implicit biases and indicate the long-term impact of teachers’ biases on students. A total of 141 undergraduate PSTs from two universities were surveyed regarding gender expectations and recognition of LGBTQ+ people. Results indicated an inconsistency between espoused beliefs and practices within the classrooms. Because schools often reflect society’s norms and perpetuate them through implicit bias, understanding what biases are currently accepted and reinforced in schools allows teacher education programs to unpack these specific biases with their preservice teachers to promote greater equality and ultimately reduce sexism in our society.
Correlation between diminished vagal tone and somatic dysfunction severity in very and extremely low birth weight preterm infants assessed with frequency spectrum heart rate variability and salivary cortisol

Osteopathic manipulative treatment (OMT) is evolving in the neonatal intensive care unit (NICU) setting. Studies showed its efficacy in length of stay and hospitalization costs reduction. Moreover, it was suggested that OMT has a modulatory effect on the preterm infants’ autonomic nervous system (ANS), influencing saturation and heart rate. Even if OMT is based on the palpatory examination of the somatic dysfunctions (SD), there are controversies about its identification and clinical relevance. The objective of this study was to evaluate the inter-rater reliability, clinical characteristics, and functional correlation of the SD Grade score with the heart rate variability (HRV) and the salivary cortisol (sCor) using a multivariate linear model approach. To evaluate those features, we implemented an ad hoc SD examination for preterm infants that was performed by 2 trained osteopaths. It was based on the new variability model of SD that includes an SD Grade assessment procedure. The ANS features were assessed by frequency parameters of HRV studying high frequency (HF), low frequency (LF), and HF/LF, whereas sCor was tested with a radioimmunoassay. The ANS assessment was standardized and performed before SD testing. Sixty-nine premature infants were eligible. SD Grade showed excellent concordance between the blinded raters. Using SD Grade as a grouping variable, the infants presented differences in GA, Apgar, pathological findings, length of stay, and ventilatory assistance. In our multivariate model, HF, LF, and LF/HF resulted linearly correlated with SD Grade. Instead, sCor presented a linear correlation with 5’ Apgar and respiratory distress syndrome but not with SD Grade. SD Grade was in line with the natural history of the underdevelopment due to prematurity. Our models indicate that the cardiac vagal tone is linearly related with SD Grade. This finding may improve the multidisciplinary decision making inside NICU and the management of modifiable factors, like SD, for cardiac vagal tone regulation.
Clinical tool to measure fluorescein patterns in orthokeratology

Background Orthokeratology (ortho-k) is an overnight clinical contact lens wear technique to correct myopia and to reduce myopia progression wearing reverse-geometry rigid gas-permeable lenses. The lens fitting procedure in clinical practice usually requires subjective assessment of fluorescein pattern (fluorescein “bull’s eye” pattern). The aim of this study was to develop a novel tool for fluorescein pattern measurements to reduce subjective practitioner dependency, especially in inexperienced practitioners, in ortho-k practice. Methods A new MATLAB customized algorithm to measure the horizontal width of the four main zones of ortho-k fluorescein patterns (central bearing, tear reservoir, mid-peripheral bearing and edge lift) was designed. The algorithm was tested on a small image database consisting of 26 ortho-k fluorescein pattern images of 13 volunteers fitted with reverse geometry lenses (Seefree, Conoptica-Hecht Contactlinsen). The agreement between two independent observers and the ImageJ measurements was determined. Results The new clinical tool provided similar measurements to ImageJ software for the central bearing (4.20 ± 0.74 and 4.27 ± 0.69 mm; P = 0.21), tear reservoir (1.69 ± 0.41 and 1.69 ± 0.45 mm; P = 0.69), mid-peripheral bearing (1.17 ± 0.11 and 1.13 ± 0.10 mm; P < 0.01) and edge lift (0.48 ± 0.06 and 0.48 ± 0.06 mm; P = 0.81) zones. Good agreement between the software (limits of agreement lower than ±0.55 mm) and inter-observer measurements (limits of agreement lower than ±0.66 mm) was found. Conclusions The proposed clinical tool for semiautomatic fluorescein pattern measurements in ortho-k could help to reduce practitioner dependency in fluorescein pattern assessment with future potential to introduce prediction algorithms or artificial intelligence methods in myopia control management.
Spectral selective composite mask media for personal cooling and efficient PM 2.5 removal

Face masks are commonly used to protect an individual’s respiratory system from inhaling fine particulate matter (PM2.5) in polluted air, as well as the airborne pathogens, especially during the ongoing coronavirus disease 2019 (COVID-19) pandemic. However, all conventional masks with anti-PM2.5 function suffer from insufficient facial thermal comfort, particularly in a hot and humid environment. Herein, we demonstrated a novel infrared-transmittance visible-opaque PM2.5 media for radiative cooling utilizing rutile titanium dioxide particle-embedded polyamide 6 (PA6-TiO2). The transmission of visible light and infrared and PM2.5 removal performance of composite media containing a variety of microstructures, such as TiO2 particles of varying sizes, shapes, and contents, were numerically examined to determine the optimal ranges. Then the PA6-TiO2 media was effectively electrospun by controlling the arrangement of fibers and the morphology of TiO2 particles. By transmitting more than 85% of the thermal radiation from the human body and selectively blocking solar irradiance, the developed PA6-TiO2(flower-shaped) media cooled the simulative skin by 10.3°C as compared with commercial masks under strong solar irradiance. Additionally, they demonstrated a high PM2.5 removal efficiency of 95.3%, a low air resistance of 22.5 Pa (at 5.3 cm/s), and a sound water vapor transmission rate of 0.0169 g cm−2 h−1. This study presents an effective strategy for making thermally comfortable anti-PM2.5 masks, which will significantly benefit the public health prevention and control.
Super-Resolution Procedure for Target Responses in KOMPSAT-5 Images

Recently, target analysis using satellite SAR images has received much attention in the area of satellite SAR remote sensing. Because the spatial resolution of the target response in the satellite SAR image is a main factor that has a large effect on target analysis performances, the improvement of the spatial resolution of target response is required to enhance the target analysis capability. However, the spatial resolution is already determined in the satellite SAR system design process. To solve the above problem, the super-resolution techniques that have been applied to radar images can be utilized. However, the application of the super-resolution techniques to the target response in the satellite SAR image is not simple due to the following reasons. First, the target’s motion induces severe blurring of the target response, which impedes the successful improvement of spatial resolution. Next, the zero-region in the frequency spectrum of the target image containing the target response also hinders the generation of the super-resolved image. To successfully improve spatial resolution of the satellite SAR image, the super-resolution techniques should be combined with proper preprocessing steps that can cope with the above two issues. In this paper, the whole super-resolution procedure for target responses in KOMPSAT-5 images is described. To the best of the authors’ knowledge, the description of the whole super-resolution procedure for target responses is the first ever attempt in the area of satellite SAR. First, a target image containing the target response is extracted from a large-scale KOMPSAT-5 image. Subsequently, the target image is transformed to be appropriate for the utilization of super-resolution techniques by proper preprocessing steps, considering the direction of super resolution and the motion of the target. Then, some super-resolution techniques are utilized to improve the spatial resolutions and qualities of the target images. The super-resolution performances of the proposed scheme are validated using various target images for point static, extended static, and extended moving targets. The novelties of this paper can be summarized as follows: (1) the practical design of whole super-resolution processing for real satellite SAR images; (2) the performance evaluation of super-resolution techniques on real satellite SAR images. The results show that the proposed scheme can led to noticeable improvements of spatial resolution of the target images for various types of targets with reliable computation times. In addition, the proposed scheme also enhanced PSLR, ISLR, and IC, leading to clearer scattering information of the principal scatterers. Consequently, the proposed method can assist in extracting more precise and meaningful information for targets represented in KOMPSAT-5 images, which means great potential for target recognition.
