Fast and nonuniform dynamics of perisaccadic vision in the central fovea
Authors: Intoy Janis , Mostofi Naghmeh , Rucci Michele 
Published: September 2021

Significance
Humans shift their gaze more frequently than their heart beats. These rapid eye movements (saccades) enable high visual acuity by redirecting the tiny high-resolution region of the retina (the foveola). But in doing so, they abruptly sweep the image across receptors, raising questions on how the visual system achieves stable percepts. It is well established that visual sensitivity is transiently attenuated during saccades. However, little is known about the time course of foveal vision despite its disproportionate importance, as technical challenges have so far prevented study of how saccades affect the foveola. Here we show that saccades modulate this region in a nonuniform manner, providing stronger and faster changes at its very center, a locus with higher sensitivity.
“The bloodiness and horror of it”
Authors: Bullo Stella 
Published: September 2021

Abstract
In this work, I explore pain descriptions by women who live with the life-altering gynaecological disease of endometriosis. This condition causes incapacitating pain, which tends to be dismissed and normalised as part of the female condition (Cumberbatch, 2019). My aim is to explore the general patterns of pain conceptualisation by women with endometriosis and outline how an in-depth examination of salient elements of narrative scenarios may contribute towards providing a comprehensive understanding of the pain experience. I first examine patterns of metaphorical pain collocates from a corpus generated from online forum contributions. Following this, I explore metaphorical scenarios of pain, focusing on stories that reference popular texts or genres from a conceptual integration perspective. I argue that the combination of metaphor analysis of naturally-occurring data and conceptual intertextuality and interdiscursivity analysis in the metaphorical scenarios of elicited data constitute a methodological niche that allows a holistic assessment of the pain that can potentially be used in consultations and may help tackle the alarming diagnosis delay of endometriosis, which is currently 7.5 years.
‘Could I have an appointment for a viewing?’
Authors: Du Bois Inke 
Published: September 2021

Abstract
This paper represents a novel approach to the study of discrimination in the housing market. Beginning with
detailed discourse analyses of several excerpts of apartment application conversations, it highlights how Standard
German, Standard American and Turkish accents interact and how power relations are reproduced on a micro-level through
interruptions and repair initiations. Furthermore, it includes the statistical report of the viewing appointments
resulting from almost 300 phone calls placed in four different city districts of the city of Bremen, Germany, with
Turkish, Standard American, and German names and accents. The neighborhoods, not the city per se, are a crucial aspect
for predicting linguistic discrimination: in the more prestigious neighborhood, Turkish accented callers had
significantly lower chances of receiving a viewing. In all but one city district, the Standard German callers received
the most viewing appointments, and the American English accented callers had more chances than the Turkish callers
speaking Standard German.
A lack of phonological inherentness
Authors: Baratta Alex 
Published: September 2021

Abstract
This paper addresses accent preference in the context of UK teaching. From this, there are
instances of trainee teachers being told to reduce their accents. The views of 32 teachers were collected and
the paper focuses on two specific points. First, it is not the sounds per se that characterise accents in
terms of positive or negative evaluations; rather, it is the societal connotations. Second, it is not merely
regional accents as such that are targeted for reduction but instead, more broad realisations of such accents.
Thus, in the context of teaching, notions of professionalism are sometimes understood differently between
teachers and mentors when viewed from a linguistic perspective, with broad accents often the target for
change.
English-language attitudes and identities in Spain
Authors: Carrie Erin 
Published: September 2021

Abstract
Language attitude research has increasingly focused on English-language learners’ evaluations of
various accents and their ability to recognise them. However, little academic attention has been paid to the
links between language attitudes and use, or language attitudes and identities. Contextualised within two
Spanish universities, this chapter explores learners’ English-mediated identities via questionnaires and
interviews, and the ways in which they negotiate possible selves within paired interactions. Quantitative data
suggest that attitudes can predict use to some extent, but qualitative data provide much deeper insights into
the negotiation of identity using rich sociolinguistic repertoires. The chapter concludes with some
reflections on the nature of the relationship between language attitudes, language use and second-language
identities.
Plasmonic nano-particles mediated energy harvesting in thin-film organic solar cells
Authors: Hamed Mohammed S G , Ike Jude N , Mola Genene Tessema 
Published: September 2021

Abstract
A Cd-doped ZnO nano-composite (Cd:ZnO) was synthesized using wet chemistry, and then incorporated into the photo-active layer of a thin film organic solar cell (TFOSC) to assist photon harvesting. The nano-composite (NC) formed different sized nano-structures that are beneficial to optical absorption and charge transport processes in the TFOSC. The effects on the NC were studied using a solar absorber medium composed of a poly(3-hexylthiophene) (P3HT) and 6-6-phenyl-C61-butyric acid methyl ester (PCBM) blend with standard device architecture: ITO/PEDOT:PSS/P3HT:PCBM/LiF/Al. The electrical and optical properties of the photoactive films were investigated at various doping levels of Cd:ZnO NC in the medium. The composite showed interesting local surface plasmon resonance, which significantly impacted on the performance of the cells. Consequently, the power conversion efficiency of the TFOSC grew by 84% compared to the reference cell. It is also noted that Cd:ZnO is environmentally stable and compatible for solution device processing.

Abstract
Light emission by inelastic tunneling (LEIT) from a metal–insulator–metal tunnel junction is an ultrafast emission process. It is a promising platform for ultrafast transduction from electrical signal to optical signal on integrated circuits. However, existing procedures of fabricating LEIT devices usually involve both top-down and bottom-up techniques, which reduces its compatibility with the modern microfabrication streamline and limits its potential applications in industrial scale-up. Here in this work, we lift these restrictions by using a multilayer insulator grown by atomic layer deposition as the tunnel barrier. For the first time, we fabricate an LEIT device fully by microfabrication techniques and show a stable performance under ambient conditions. Uniform electroluminescence is observed over the entire active region, with the emission spectrum shaped by metallic grating plasmons. The introduction of a multilayer insulator into the LEIT can provide an additional degree of freedom for engineering the energy band landscape of the tunnel barrier. The presented scheme of preparing a stable ultrathin tunnel barrier may also find some applications in a wide range of integrated optoelectronic devices.

Authors: Zhang Wei , Meng Xiao , Liu Wenjie , Li Baorang 
Published: September 2021

Abstract
Antioxidant graphite was prepared from Al(H2PO4)3 solution by solution impregnation method. The as-prepared antioxidant graphite was further compounded with phase change materials for heat storage depending upon the form-stable technique. SEM with EDS analyses were used to characterize both the morphology and microstructure of the impregnated graphite while DSC were used to measure thermal properties of the composite. The results showed that the best impregnation mass ratio of Al(H2PO4)3to graphite should be 2:1∼3:1. In this case, the obtained composite heat storage material can realize certain oxidation resistance and obtain good heat storage performance after thermal cycling.

Authors: Hou Yufei , Xu Jinsheng , Zhou Changsheng , Chen Xiong 
Published: September 2021

Abstract
Impregnation capability at particle-matrix interfacial deteriorates during the preparation of composite solid propellant due to manufacturing and environmental factors, which leads to the initial defects in the HTPB solid propellant. In the present work, the effects of initial particle-matrix interfacial defects on the debonding, nucleation, and crack propagation of the composite solid propellant is investigated experimentally and numerically. A random packing model is developed based on the molecular dynamics method by embedding AP particles in the HTPB propellant. The strength of particle-matrix interface obeys Weibull function. Moreover, a zero-thickness cohesive element is used to simulate the particle-matrix interfacial debonding and matrix rupture. According to the simulation and experiment results, the initial interface defects makes a marked effect on the initial modulus, limit strength and elongation at fracture of the composite solid propellant. The initial modulus, limit strength and elongation at fracture of the composite solid propellant decrease with the increase of the initial interface defects.

Published: September 2021

Abstract
In order to promote the exploration and development of oil reservoirs in northern Shaanxi, the study of sedimentary facies characteristics in D area was carried out. Using core, logging and logging data, the Yan 9 oil layer group in the D area is divided into two small layers, Yan 91+2 and Yan 93. Based on the core description, the analysis of single-well sedimentary facies, continuous-well sedimentary facies, and planar sedimentary facies is carried out. It is believed that the Yan 9 member of the study area is a delta plain deposit, which is mainly composed of distributary channels, natural embankment and inter-branch swamp microfacies. Vertically, the sand bodies in the Yan 9 oil-bearing group are discontinuous, with distributary channels and inter-branch swamps mainly developed. Horizontally, the channels of the Yan 9 oil layer group spread out in strips on the plane, extending in the northwest-south east direction. There are 6 main rivers in the study area of Yan93 stage and 7 main rivers in Yan91+2 stage. Channel deposits constitute the main body of the sand body skeleton and are also the main oil and gas enrichment area.

Published: September 2021

Abstract
It is of great significance for the construction and operation of high head pumped storage power station, high dam project and deep tunnel project to master the seepage characteristics and laws of rock mass shear fracture. In this paper, the seepage characteristics of marble shear fractures are summarized as follows. (1) In the radial seepage test, the seepage process conforms to darcy’s law, and there is a linear relationship between head pressure and flow. (2) The characteristics of local tensile failure in the cracks generated under low normal force during the shear process hinder the seepage. (3) The normal force has a significant influence on the fracture seepage. In the process of the normal force increasing from 36kN to 48kN, the seepage characteristics show a sudden change, and the contact form of the shear fracture surface changes, indicating that part of the seepage channel in this stage appears a closed phenomenon with the increase of the normal force, and a large area of closure is formed in the fracture.

Published: September 2021

Abstract
The wire feed laser welding has significant merits in metal joining technology for the manufacturing industry, which including high energy efficiency, high welding speed, automated workflow and narrow heat-affected zone. During to the interaction between weld pool and welding wire, the welding process is more complicated. In this work, a numerical model to the wire feed laser welding for the liquid bridge transition was built. By constructing a movable welding wire entity accurately, the simulation result for flow and heat transfer inside weld pool and welding wire were acquired by the numerical solution. The temperature field, velocity field and weld appearance can be obtained by simulation results. The results shown that the rapid wire feed speed will increase the heat absorption of welding wire, which can improve the hardness due to higher cooling rate. Through the analysis of experimental and simulation results, the quantitative relationship between weld parameters and weld result can be obtained. The numerical simulation can guide the optimization of welding parameters and control the weld appearance.

Abstract
The finite element simulation was performed for 8 carbon fiber reinforced plastic (CFRP) sheets reinforced steel-concrete composite beams via ABAQUS software, in an effort to further investigate their mechanical properties. Next, the influences of shear connection degree and elasticity modulus, width and constitutive relation of CFRP sheets on the mechanical properties of steel-concrete composite beams were studied. Subsequently, their load-dependent change laws of midspan deflection were reported in detail. The simulation results show that the reinforcement effect on the negative moment region of each composite beam is improved with the increase in the elasticity modulus, width of CFRP sheets and the shear connection degree.

Authors: Chen Dengkai , Zhong Jiuqiang , Zhu Bitang , Jiang Yalong 
Published: September 2021

Abstract
A fluid-solid coupling numerical model was established for unsaturated red clay, which is prone to causing clustered landslides under three typical heavy precipitations in southwest China, to investigate the influence of the precipitation patterns on the infiltration mode, pore water pressure and stability of unsaturated red clay slopes. The investigation showed that (1) during heavy precipitation, much rainwater tends to form a transient saturated zone in the shallow layers of the slopes in a short time, thereby reducing the matric suction of the soil matrix; (2) under short-term continuous rainstorm, the pore water pressure dropped to the greatest extent; and (3) the safety factor experienced the largest decrease under persistent heavy precipitation following 24-hour rainfall, while slopes displaced the most under sudden rainstorm.
Study on mechanical properties of basalt fiber reinforced coral concrete under loading
Authors: Zhou Hao , Wu Qing 
Published: September 2021

Abstract
Basalt fiber and cement are easy to disperse concrete and mortar, so basalt fiber reinforced concrete plays the role of reinforcement, crack prevention and crack resistance. The basalt fiber has good ductility and corrosion resistance, which can replace the traditional concrete and is widely used in construction engineering. In order to improve the strength of coral concrete in marine engineering, the compressive strength and creep properties of coral concrete mixed with basalt fiber were tested, and the creep prediction model suitable for coral concrete was established. The experimental results show that the effect of basalt fiber on the compressive strength of reinforced concrete is not significant; The creep behavior of basalt fiber reinforced coral concrete is higher than that of ordinary concrete; By modifying the existing creep model, a creep prediction model suitable for coral concrete is established. These experimental results can provide a reference for the design of coral concrete structures in ocean engineering.
Research on structural design and anti-penetration performance of ceramic composite armor
Authors: Zou Youchun , Xiong Chao , Yin Junhui , Deng Huiyong , Cui Kaibo 
Published: September 2021

Abstract
Two types of composite armor were designed (Composite armor I alumina ceramic/Kevlar/616 armored steel; Composite armor II alumina ceramic/616 armored steel/Kevlar). Through penetration tests and numerical simulations, the anti-penetration performance and anti-penetration mechanism of the composite armors were studied, and the influences of material arrangement on its anti-penetration performance were discussed. The results show that the established finite element models can reliably simulate the penetration process of composite armors. The failure modes of Kevlar and 616 armored steel in composite armor I are tensile failure and spalling damage, respectively. The failure mode of Kevlar and 616 armored steel in composite armor II is shear failure. The shear failure of 616 armored steel and Kevlar is a low energy consumption damage mode. Therefore, the structure form of composite armor I can give full play to the anti-penetration performance of the material, and the anti-penetration performance is better than that of composite armor I.

Published: September 2021

Abstract
At present, the development of clastic reservoir has become an important way to increase oil and gas productivity in China, and the exploitation of oil and gas will inevitably affect the mechanical properties of rocks. Therefore, it is of great significance to study the rock mechanical properties of clastic reservoir rock. In this paper, the path tests of axial pressure rising-confining pressure rising and axial pressure constant-confining pressure unloading are carried out on the clastic rock samples. The results show that the clastic rock exhibits obvious elastoplastic characteristics under the path of rising confining pressure, but has certain characteristics of elasticity and brittleness under the path of unloading confining pressure; The increase in confining pressure can effectively inhibit the expansion of the rock and increase its bearing capacity; At the same initial confining pressure, the loading failure is less severe than the unloading failure; In the unloading path, the damage of the rock sample during the deformation and failure process is higher; As the confining pressure increases, the degree of rock damage also increases.
