A corpus-assisted qualitative approach to political discourse in
Spanish print and digital press
Authors: Fernández Smith Gérard 
Published: October 2020

Abstract
News discourse nowadays is generally regarded as
a means for the transmission of ideology and other predefined ideas,
usually related to political viewpoints and, therefore, political
discourses. From this standpoint (widely discussed by van Dijk,
Fairclough, and Wodak, among others), I intend to achieve an
adequate qualitative description of conceptual networks and some
general patterns of persuasive communicative goals throughout data
obtained from written pieces of discourse in Spanish media, focusing
my attention on a series of key words, frequently used by
politicians and reproduced by the media, previously gathered from
Spanish main parties’ electoral programs. My assumption is that,
being involved with political ideology, patterns found within news
discourse support the idea that a positive or a negative position is
defended regarding those contents represented by said key words.
A visual critical discourse analysis of women representation in
Dolce & Gabbana advertising
Authors: Martínez Lirola María 
Published: October 2020

Abstract
The role of visuals in meaning making is
essential to communicate and establish a dialogue with society. The
aim of this chapter is to uncover the visual discursive
representation of women in a sample of advertisements from a
critical discourse analysis perspective. Data was collected via the
Internet from the advertisements by Dolce & Gabbana from January
2016 to December 2018. The data was quantitatively analysed
following van Leeuwen’s model of social actors and Kress and van
Leewen’s visual grammar within the general frame of visual critical
discourse analysis. This chapter critically studies the
advertisements used by Dolce & Gabbana for their products and
examines whether visual choices used by the publicist to portray the
woman in the corpus contribute to perpetuating gender stereotypes.
The findings indicate that women are represented as stereotyped,
following traditional canons of beauty and foregrounding their
bodies as objects of desire.
“Well, in the case of my mom…”
Authors: Lukianova Ekaterina , Steffensmeier Timothy 
Published: October 2020

AbstractThis article is guided by the question: What are the argumentative functions of personal stories in public deliberations? Drawing on the analytical traditions of argumentation theory and discourse analysis, we analyzed three public forums on mental illness, where personal stories were used in a number of argumentative functions. Our analysis reveals that in a deliberative forum personal stories were used as negotiable arguments rather than as mere assertions of individual experience. Personal stories were primarily used as arguments by example to challenge the framing proposed by the moderator and to pitch problem definitions that participants considered most relevant. In this function, personal stories were alternatively engaged as inductive or abductive arguments by other forum participants. Additionally, personal stories were used to support solution proposals and to uphold social ideals.
Polar modes of gravitational waves in Rastall cosmology
Authors: Salti M , Aydogdu O , Kangal E E 
Published: October 2020

Abstract
In this article, we discuss propagation expressions for polar gravitational waves in the spatially flat Friedmann–Lemaitre–Robertson–Walker spacetime dominated by a perfect fluid in the Rastall theory. We perturb the spatially flat spacetime description by making use of Regge–Wheeler perturbations inducing the polar gravitational waves and formulate the corresponding field equations for both unperturbed and perturbed cases. Then, we focus on these field equations simultaneously to find out the unknown perturbation functions. We attain that the assumed perturbations affect the background matter distribution as well as the four-velocity components. We also investigate the impact of model parameters on the amplitude of the polar gravitational waves.

Published: October 2020

Abstract

Objective: Sitting-acquired pressure ulcers (PUs) are common in wheelchair users. These PUs are often serious and may involve deep tissue injury (DTI). Investigating the mechanical properties of the tissues susceptible to DTI may help in guiding the prevention and early detection of PUs. In this study, shear wave elastography (SWE) was used to measure the normative mechanical properties of the soft tissues of the buttocks, i.e. skeletal muscle and subcutaneous fat, under the ischial tuberosities, in a convenient sample of healthy adults without weight bearing and with weight bearing of different times. Approach: We compared the stiffness properties of these soft tissues between the lying prone and sitting postures, to determine whether there are detectable property changes that may be associated with the type of posture. We hypothesized that muscle contractions and 3D tissue configurations associated with the posture may influence the measured tissue stiffnesses. Main results: Our results have shown that indeed, SWE values differed significantly across postures, but not over time in a specific posture or for the right versus left sides of the body. Significance: We have therefore demonstrated that soft-tissue stiffness increases when sitting with weight bearing and may contribute to increasing the potential PU risk in sitting compared to lying prone, given the stiffer behavior of tissues observed in sitting postures.

Published: October 2020

Abstract
This article systematically studies and compares the Brillouin characteristics of single-mode fiber (SMF), few-mode fiber (FMF) and multi-mode fiber (MMF). The Brillouin frequency shift (BFS), Brillouin linewidth, gain peak, and Brillouin gain spectrum of different types of optical fibers in the case of single mode and mode superposition are investigated. The results show that in single mode case, the BFS, Brillouin linewidth, and gain peak of the FMF and MMF decrease as the mode order increases. Considering the mode superposition case, the SMF has the largest BFS, followed by the MMF, and the smallest is FMF. The MMF has the largest Brillouin linewidth, followed by the FMF, and the smallest is SMF. The SMF has the largest gain peak, followed by FMF, and the smallest for MMF. This work provides an important reference value for the further study of Brillouin distributed fiber optical sensors.

Abstract
The industrial systems has became more complex, because of the rapid development of industrial production. Large time-delay, time variation, and highly nonlinear have placed higher requirements on industrial control systems. Smith predicting controller is a controller specifically used for time-delay systems. It estimates the dynamic characteristics of the system’s basic disturbances in advance, and designs an estimator for compensation control, which can effectively improve the system response. But Smith predicting controller depends too much on the mathematical model of the controlled object. This paper proposed a control system based on Smith-PIDNN, which combines Smith controller with neural network PID (PIDNN), uses the neural network’s ability to simulate non-linear systems and self-learning ability, and adjusts control parameters online. And it was simulated by MATLAB software, the effectiveness of this combination method was proved.

Analysis of the influence of tool radius on single crystal silicon cutting process based on Molecular dynamics
Authors: Lai Lianfeng , Niu Qinchuan , Li Minglin 
Published: October 2020

Abstract
In this paper, a molecular dynamics method is used to construct a simulation model for cutting single crystal silicon with a tool. Through the analysis of phase transition, instantaneous atomic position, temperature, Wigner-Seitz defect and other variables, the influence of tool radius on material deformation is studied. The results show that in the process of cutting single crystal silicon, the contact area between the cutting edge and the single crystal silicon workpiece is the main area of cutting heat generation, and the phase change process from the atomic crystalline state to the amorphous state is reflected in the cutting process of different tool radii The difference is that the amorphous atoms are removed in the form of chips during the cutting process of the sharp-angle tool, while the amorphous atoms are further compressed directly under the tool in the round-angle tool, causing subsurface damage. The chip removal mechanism of sharp tools is shear, and the chip removal mechanism of round tools is shear and extrusion. As the radius of the tool increases, the more atoms are compressed directly below the tool, the worse the surface quality of the machined surface.
