The Use of Statistical Functions for the Selection of Laser Texturing Parameters
Authors: Sęk Piotr 
Published: July 2020

Abstract
Laser surface texturing is currently the most developed technique for producing fully reproducible microcavities on the surfaces of machine elements. From the point of view of texture technology, an important aspect is the proper selection of process parameters to obtain texture elements with desirable and repetitive geometries and physicochemical properties. Surface texturing improves mottling and fretting resistance and is also used wherever the adhesion properties of surface layers (printing techniques, bonding materials, biological and chemical activity, coatings, etc.) are important. The article shows the possibility of applying statistical functions to the selection of appropriate machining parameters to obtain microgeometry useful in the application of textured surfaces [1].

Abstract
Metabolic disorders, including obesity, diabetes, and hyperlipidemia, as well as cardiovascular diseases (CVD), particularly atherosclerosis, are still leading causes of death worldwide. Plasma levels of low-density lipoprotein (LDL) are currently being considered as a critical risk factor for the diseases mentioned above, especially atherosclerosis. Because of the heterogeneous nature of LDL, many studies have already been conducted on its subclasses, especially small dense LDL (sdLDL). According to available evidence, sdLDL levels can be considered as an ideal alternative to LDL levels for monitoring CVD and early diagnosis of atherosclerosis. Recently, several researchers have focused on factors that are able to decrease sdLDL levels and improve health quality. Therefore, the purpose of this study is to describe the production process of sdLDL particles and review the effects of pharmaceutical and dietary agents as well as lifestyle on sdLDL plasma levels. In brief, their mechanisms of action are discussed. Apparently, cholesterol and LDL-lowering compounds are also effective in the reduction of sdLDL levels. In addition, improving lipid profile, especially the reduction of triglyceride levels, appropriate regimen, and lifestyle can decrease sdLDL levels. Therefore, all the aforementioned parameters should be taken into consideration simultaneously in sdLDL levels reducing strategies.
Desire and confusion: A sociolinguistic ethnography on affect in the ethnic economy of Thai massage
Authors: Flubacher Mi-Cha 
Published: July 2020

Abstract
In my contribution, I will look at the interconnections between language, work, ethnicity and gender in the exemplary site of the Thai massage studio as part of a larger sociolinguistic ethnography in Vienna, Austria. I argue that Thai massage therapists are trying to establish an independent and professional self, while being continuously repositioned along gendered and racial stereotypes based on post-colonial ideas of the “exotic woman”. In other words, their work empowers them on the local labour market, but simultaneously threatens to reinstall clear social and ethnical hierarchies. In order to unpack this complex, I propose to discuss two theoretical concepts from a critical sociolinguistic perspective: the ethnic economy and the affect of desire, as they both inform an understanding of Thai massage as a particular localised global practice. I will first discuss ambivalent opportunities related to language competences in the ethnic economy, and then turn to examine how male clients come to ascribe “confused affect” to their experience with desire in the Thai massage. Finally, I will discuss the issue of researcher positionality in dealing with the potential reproduction of exoticisation through research.
Theoretical analysis of the influence of plane control network on lateral breakthrough error of long immersed tunnel

Published: July 2020

Abstract
There is extremely strict precision requirement for the lateral breakthrough error of long immersed tunnel in the offshore island and tunnel project, but the point location layout range of the outer plane control network is limited in the artificial island, and the space inside the tunnel is long and narrow, which is not conducive to high-precision through-measurement control. In order to further reduce the influence of the error of the plane control network on the lateral breakthrough error of the immersed tunnel, a mathematical model of the influence of the lateral breakthrough error caused by the orientation direction of the outer control point and the position of the breakthrough point has been established through the theoretical analysis in this study, and the favorable orientation directions and the favorable penetration point are analyzed. It is suggested through simulation analysis that the direction that is as consistent with that from the entrance (outlet) point to the penetration point as possible is as the advantageous orientation, which could minimize the lateral penetration error and ensure high-precision rendezvous and docking of the immersed tunnel. This study is instructive for similar engineering practices.
Reduced basis approximations of the solutions to spectral fractional diffusion problems
Authors: Bonito Andrea , Guignard Diane , Zhang Ashley R. 
Published: July 2020

AbstractWe consider the numerical approximation of the spectral fractional diffusion problem based on the so called Balakrishnan representation. The latter consists of an improper integral approximated via quadratures. At each quadrature point, a reaction–diffusion problem must be approximated and is the method bottle neck. In this work, we propose to reduce the computational cost using a reduced basis strategy allowing for a fast evaluation of the reaction–diffusion problems. The reduced basis does not depend on the fractional power s for 0 < smin ⩽ s ⩽ smax < 1. It is built offline once for all and used online irrespectively of the fractional power. We analyze the reduced basis strategy and show its exponential convergence. The analytical results are illustrated with insightful numerical experiments.

Published: July 2020

Abstract
Exercise during pregnancy may be beneficial provided that there are no contraindications. The aim of this study was to summarize and compare recommendations regarding exercise in pregnancy. Thus, a comparative descriptive review was conducted and included guidelines by the American College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynaecologists of Canada and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists. All compared guidelines recommend that pregnant women without contraindications should undertake physical activities regularly, however, the type of workout performed should be adjusted based on the previous exercise experience and the physical condition of each pregnant woman. A variation among the reviewed guidelines was identified on appropriate and inappropriate activities and on indications to interrupt exercise. To summarize, the adoption of an international up-to-date consensus regarding appropriate exercise during pregnancy may be beneficial in ensuring the safety of the pregnant women while promoting their physical and mental health.

Published: July 2020

AbstractThe goal of this paper is to discuss the well-posedness and the generalized well-posedness of a new kind of differential quasi-variational-hemivariational inequality (DQHVI) in Hilbert spaces. Employing these concepts, we explore the essential relation between metric characterizations and the well-posedness of DQHVI. Moreover, the compactness of the set of solutions for DQHVI is delivered, when problem DQHVI is well-posed in the generalized sense.

Published: July 2020

Abstract
This study pursues an investigation on L-semihypergroups equipped with an L-order. First, the concept of L-ordered L-semihypergroups is introduced by L-posets and L-semihypergroups, and some related results are obtained. Then, prime, weakly prime, and semiprime L-hyperideals of L-ordered L-semihypergroups are studied. Moreover, the relationships among the three types of L-hyperideals are established. Finally, the intra-regular L-ordered L-semihypergroups are characterized in terms of these L-hyperideals. The results of the study show that some well-known results on ordered semihypergroups also hold in the case of L-ordered L-semihypergroups.

Published: July 2020

AbstractThis article describes a long-term study evaluating the use of the humanoid robot Kaspar in a specialist nursery for children with autism. The robot was used as a tool in the hands of teachers or volunteers, in the absence of the research team on-site. On average each child spent 16.53 months in the study. Staff and volunteers at the nursery were trained in using Kaspar and were using it in their day-to-day activities in the nursery. Our study combines an “in the wild” approach with a rigorous approach of collecting and including users’ feedback during an iterative evaluation and design cycle of the robot. This article focuses on the design of the study and the results from several interviews with the robot’s users. We also show results from the children’s developmental assessments by the teachers prior to and after the study. Results suggest a marked beneficial effect for the children from interacting with Kaspar. We highlight the challenges of transferring experimental technologies like Kaspar from a research setting into everyday practice in general and making it part of the day-to-day running of a nursery school in particular. Feedback from users led subsequently to many changes being made to Kaspar’s hardware and software. This type of invaluable feedback can only be gained in such long-term field studies.
Varieties of abstract concepts and their grounding in perception or action
Authors: Kiefer Markus , Harpaintner Marcel 
Published: July 2020

AbstractFor a very long time, theorizing in the cognitive sciences was dominated by the assumption that abstract concepts, which lack a perceivable referent, can only be handled by amodal or verbal linguistic representations. In the last years, however, refined grounded cognition theories emphasizing the importance of emotional and introspective information for abstract concepts, in addition to verbal associations and sensorimotor information, have received increasing support. Here, we review theoretical accounts of the structure and neural basis of conceptual memory and evaluate them in light of recent empirical evidence with regard to the processing of concrete and abstract concepts. Based on this literature review, we argue that abstract concepts should not be treated as a homogenous conceptual category, whose meaning is established by one single specific type of representation. Instead, depending on the feature composition, there are different subgroups of abstract concepts, including those with strong relations to vision or action, which are represented in the visual and motor brain systems similar to concrete concepts. The reviewed findings with regard to concrete and abstract concepts can be accommodated best by hybrid theories of conceptual representation assuming an interaction between modality-specific, multimodal and amodal hub areas.
Investigation of effective parameters on SAPO-34 nanocatalyst in the methanol-to-olefin conversion process: a review
Authors: Yang Zhidong , Zhang Liehui , Zhou Yuhui , Wang Hui , Wen Lichen , Kianfar Ehsan 
Published: July 2020

AbstractLight olefins such as ethylene, propylene and butylene are mainly used in the petrochemical industry. Due to the growing need for light olefins in the industry and the future shortage of petroleum resources, the process of converting methanol to olefins (MTO) using non-oil sources has been considered as an alternative. Coal and natural gas are abundant in nature and the methods of converting them to methanol are well known today. Coal gasification or steam reforming of natural gas to produce synthetic gas (CO and hydrogen gas) can lead to methanol production. Methanol can also be catalytically converted to gasoline or olefins depending on the effective process and catalyst factors used. Due to the use of crude methanol in the MTO unit and because the feed does not require primary distillation, if the MTO unit is installed alongside the methanol unit, its capital costs will be reduced. The use of methanol can have advantages such as easier and less expensive transportation than ethane. Among the available catalysts, SAPO-34 is the most suitable catalyst for this process due to its small cavities and medium acidity. One of the problems of MTO units is the rapid deactivation of SAPO-34, which can also be affected by the synthesis factors, so it is possible to optimize the catalyst performance by modifying the synthesis conditions. In this article, we will introduce the MTO process and the factors affecting the production of light olefins.

Published: July 2020

AbstractThis study analyses a literary topos concerning the abundance of natural phenomena, including fresh water, reed beds and fish. The standardised sequence listing such abundant natural features occurs in two previously unpublished tablets containing Emesal prayers concerning the god Enki, published in this article. The Old Babylonian tablet, of unknown provenance, attests to a unique composition. The tablet from Late Babylonian Ur, which is partially paralleled by a previously known manuscript, includes performative indications.

Nouveaux joints relatifs au grand rituel louvite de Kuwattalla et Šilalluḫi
Authors: Sasseville David 
Published: July 2020

AbstractIn his edition of Cuneiform Luwian texts, Starke categorizes the rituals of Kuwattalla into three groups. While the existence of the first two in which Šilalluḫi participates is secured, the third one is highly hypothetical. In this paper, new joins of fragments made by the author are presented, which confirm the recent arguments of Hutter against the third ritual of Starke and bear consequences for the rearrangement of the rituals of the Kuwattalla tradition. Furthermore, it is shown that the various redactions of the Great Ritual were not kept in the same archives at the city of Ḫattuša.
Houses with a Central Courtyard. House Concepts in the Late Ninevite 5 Period at Tell Arbid
Authors: Smogorzewska Anna 
Published: July 2020

AbstractHouses with central courtyards, examples of which were uncovered at Tell Arbid, show that standardization in house plans and spatial organization characteristic for EJZ 3 domestic architecture, can be traced back to the late Ninevite 5 period. Houses of this type were built at plots of lands and had a regular internal layout. Also in terms of socio-economic organization houses with central courtyards of late Ninevite 5 date can be regarded as a reference to the EJZ 3 period.
Elevated pressure low-temperature oxidation of linear five-heavy-atom fuels: diethyl ether, n-pentane, and their mixture

Abstract
Diethyl ether (DEE) has been proposed as a biofuel additive for compression-ignition engines, as an ignition improver for homogeneous charge compression ignition (HCCI) engines, and as a suitable component for dual-fuel mixtures in reactivity-controlled compression ignition (RCCI) engines. The combustion in these engines is significantly controlled by low-temperature (LT) chemistry. Fundamental studies of DEE LT oxidation chemistry and of its influence in fuel-mixture oxidation are thus highly important, especially at elevated pressures. Elevated pressure speciation data were measured for the LT oxidation of DEE, of its similarly-structured linear five-heavy-atom hydrocarbon fuel (n-pentane), and of a mixture of the two fuels in a jet-stirred reactor (JSR) in the temperature range of 400–1100 K and at various pressures up to 10 bar. The pressure influence on the LT oxidation chemistry of DEE was investigated by a comparison of the measured profiles of oxidation products. The results for DEE and n-pentane were then inspected with regard to fuel structure influences on the LT oxidation behavior. The new speciation data were used to test recent kinetic models for these fuels [Tran et al., Proc. Combust. Inst. 37 (2019) 511 and Bugler et al., Proc. Combust. Inst. 36 (2017) 441]. The models predict the major features of the LT chemistry of these fuels well and could thus subsequently assist in the data interpretation. Finally, the LT oxidation behavior of an equimolar mixture of the two fuels was explored. The interaction between the two fuels and the effects of the pressure on the fuel mixture oxidation were examined. In addition to reactions within the combined model for the two fuels, about 80 cross-reactions between primary reactive species generated from these two fuel molecules were added to explore their potential influences.

Background:
The ‘3PAs’ syndrome, associating pituitary adenoma (PA) and pheochromocytoma/paraganglioma (PPGL), is sometimes associated with mutations in PPGL-predisposing genes, such as SDHx or MAX. In ’3PAs’ syndrome, PAs can occur before PPGL, suggesting a new gateway into SDHx/MAX-related diseases.

Objective:
To determine the SDHx/MAX mutation prevalence in patients with isolated PAs and characterize PAs of patients with SDHx/MAX mutations.

Design:
Genes involved in PAs (AIP/MEN1/CDKN1B) or PPGLs (SDHx/MAX) were sequenced in patients with isolated PAs. We then conducted a review of cases of PA in the setting of ’3PAs’ syndrome.

Results:
A total of 263 patients were recruited. Seven (likely) pathogenic variants were found in AIP, two in MEN1, two in SDHA, and one in SDHC. The prevalence of SDHx mutations reached 1.1% (3/263). Of 31 reported patients with PAs harboring SDHx/MAX mutations (28 published cases and 3 cases reported here), 6/31 (19%) developed PA before PPGL and 8/31 (26%) had isolated PA. The age of onset was later than in patients with AIP/MEN1 mutations. PAs were mainly macroprolactinomas and showed intracytoplasmic vacuoles seen on histopathology.

Conclusions:
We discovered SDHx mutations in patients bearing PA who had no familial or personal history of PPGL. However, the question of incidental association remains unresolved and data to determine the benefit of SDHx/MAX screening in these patients are lacking. We recommend that patients with isolated PA should be carefully examined for a family history of PPGLs. A family history of PPGL, as well as the presence of intracytoplasmic vacuoles in PA, requires SDHx/MAX genetic testing of patients.

Context:
Accurate hydrocortisone dosing in children with adrenal insufficiency is important to avoid the risks of over and under treatment including iatrogenic Cushing’s syndrome and adrenal crisis.

Objective:
To establish a population pharmacokinetic model of hydrocortisone in children and use this to refine hydrocortisone replacement regimens.

Design and methods:
Pharmacokinetic study of hydrocortisone granules, available in 0.5, 1, 2 and 5 mg dose strengths, in 24 children with adrenal insufficiency aged 2 weeks to 6 years. Cortisol concentrations quantified by LC-MS/MS were used to refine an adult pharmacokinetic model to a paediatric population model which was then used to simulate seven different hydrocortisone treatment regimens.

Results:
Pre-dose cortisol levels were undetectable in 54% of the 24 children. The developed pharmacokinetic model had good predictive performance. Simulations for the seven treatment regimens using either three- or four-times daily dosing showed treatment regimens delivered an AUC0-24h within the 90% reference range for healthy children except in neonates where two regimens had an AUC below the 5th percentile. Cortisol concentrations at individual time points in the 24 h were outside the 90% reference range for healthy individuals in 50%, 55–65% and 70–75% for children, infants and neonates, respectively, with low cortisol levels being most prevalent.

Conclusions:
Current paediatric hydrocortisone treatment regimens based on either three- or four-times daily administration replicate cortisol exposure based on AUC0-24h, but the majority of cortisol levels are above or below physiological cortisol levels with low levels very common before the next dose.
