Ethics and Robot Democratization: Reflecting on Integrative Ethics Practices
Authors: de Pagter Jesse 
Published: May 2023

AbstractThis paper aims to address the need for new integrative approaches to aid the further development of robot ethics as a research field. It presents observations gathered in a collaborative robotics project that pursued an integrative ethics approach. The paper first contextualizes the increasing attention to ethical approaches in robotics development, design and implementation. Several existing considerations and attempts to further integrate ethics into the field of robotics are reviewed, while also providing context with respect to new trends that generate new possibilities for integrating ethical approaches into robotics and human-robot interaction research. Subsequently, the paper elaborates on the specificities of the collaborative robotics project that pursued an integrative approach. The collaborative robot is presented as a specific type of technological artifact, and insight is given into the project’s aim to “democratize” this technology. Furthermore, practices required to integrate ethics are reviewed based on the author’s observations and experiences in the project. Finally, to contribute to the further development of integrative approaches in robot ethics, these observations are developed into three constitutive components that should aid the further development of integrative robot ethics approaches, namely: increased attention for the way interdisciplinarity is defined in the field of robot ethics, the role and nature of ethical critique, and finally the chances integrative approaches offer for the development of more thorough anticipatory concepts.
A characterisation study of ignimbrites of Tenerife Island employed as building stone
Authors: Valido José A. , Cáceres José M. , Sousa Luís 
Published: May 2023

AbstractThe objective of this study is to evaluate the petrophysical properties of four ignimbrites employed as dimension stones. The natural stone under study is produced in Tenerife Island (Spain) under the commercial brand name of Piedra Chasnera and are differentiated according to their chromatic variety into: brown, violet, grey and green. To assess the suitability for feasible applications, it is essential to have a comprehensive knowledge of its properties. In this respect, mineralogical, petrographic and chemical properties were obtained by X-ray diffraction (XRD), polarisation microscopy (POM) and X-ray fluorescence (XRF). According to the procedure described in the standardised methods, apparent density, open porosity, water absorption at atmospheric pressure, water absorption coefficient by capillary and ultrasound propagation velocity were measured. The four variants of ignimbrites were analysed and classified according to the results obtained. It was found that the properties vary depending on the depth of the stratigraphic volcanic level from which the stone is extracted. From the review of the published data, it can be seen that the test results are within the expected values for this lithotype. A comparison was also made with other types of dimensional stones. The correlation analysis shows that there is a high degree of correlation between the physical properties studied.
A new approach for post-fracturing evaluation and productivity prediction based on a reservoir fracability index model in shale gas reservoirs
Authors: Liu Shanyong , Cao Nai , Lou Yishan , Yuan Yuan 
Published: May 2023

AbstractMultistage fracturing technology is the primary means of reservoir stimulation in shale gas wells. However, the productivity contribution of each stage varies greatly. It is essential to evaluate the fracturing effect in order to make an optimized treatment design. In this study, we adopted an integrated workflow to assess the main control factors of geological and engineering parameters and a novel approach was proposed for post-fracturing evaluation. For this purpose, the H block in Zhaotong shale gas demonstration zone in Sichuan, China, has been taken as an object of study. The production predicting model was built based on the reservoir fracability index (RFI) which took both fluid type and proppant size differences into consideration. The results demonstrated that (1) if the reservoir quality index (RQI) in the target zone is greater than 5.0, then the area has good reservoir quality and development potential. (2) The RFI of H Block is generally at 4.0–6.0, it can be used as the key parameter to screen out the sweet spot. This method not only serves as a set of practical fracturing evaluation methods but also as a set of productivity prediction and fracturing optimization methods, which can provide strong support for the development of shale gas reservoirs.
Identification of screw spacing on pediatric hip locking plate in proximal femoral osteotomy

Published: May 2023

AbstractThis study describes a computational analysis technique for evaluating the effect of screw spacing and angle on the pediatric hip locking plate system in proximal femoral osteotomy in pediatric patients having DDH with an aberrant femoral head and femoral angle. Under static compressive load conditions, the stresses of the screw and bone were examined as the screw spacing and angle changed. The spacing and angle of various screws were specifically considered as variables in this study based on the pile mechanism studied in civil engineering. As with the group pile mechanism, the tighter the screw spacing under static compressive loads, the more the overlapping effect between the bone stresses and the screws develops, increasing the risk of injuring the patient’s bone. Therefore, a series of simulations was performed to determine the optimal screw spacing and angles to minimize the overlapping effect of bone stress. In addition, a formula for determining the minimum screw spacing was proposed based on the computational simulation results. Finally, if the outcomes of this study are applied to pediatric patients with DDH in the pre-proximal femoral osteotomy stage, post-operative load-induced femur damage will be reduced.

Published: May 2023

Abstract
Purpose of Review
Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder in women of reproductive age worldwide. This disease causes menstrual, metabolic, and biochemical abnormalities such as hyperandrogenism, oligo-anovulatory menstrual cycles, polycystic ovary, hyperleptinemia, insulin resistance (IR), and cardiometabolic disorders, often associated with overweight or obesity and visceral adiposity.

Recent Findings
The etiology and pathophysiology of PCOS are not yet fully understood, but insulin seems to play a key role in this disease. PCOS shares an inflammatory state with other chronic diseases such as obesity, type II diabetes, and cardiovascular diseases; however, recent studies have shown that a healthy nutritional approach can improve IR and metabolic and reproductive functions, representing a valid therapeutic strategy to ameliorate PCOS symptomatology.

Summary
This review aimed to summarize and collect evidence about different nutritional approaches such as the Mediterranean diet (MedDiet) and the ketogenic diet (KD), as well as bariatric surgery and nutraceutical supplementation as probiotics, prebiotics, and synbiotics, among the others, used in patients with PCOS.

Abstract
Introduction
Cancer-related pain is common and undertreated. Exercise is known to have a pain-relieving effect in non-cancer pain.

Objectives
This systematic review aimed to evaluate (1) the effect of exercise on cancer-related pain in all cancers, and (2) whether the effect of exercise differed according to exercise mode, degree of supervision, intervention duration and timing (during or after cancer treatment), pain types, measurement tool and cancer type.

Methods
Electronic searches were undertaken in six databases to identify exercise studies evaluating pain in people with cancer, published prior to 11 January 2023. All stages of screening and data extraction were conducted independently by two authors. The Cochrane risk of bias tool for randomised trials (RoB 2) was used and overall strength of evidence was assessed using the GRADE approach. Meta-analyses were performed overall and by study design, exercise intervention and pain characteristics.

Results
In total, 71 studies reported in 74 papers were eligible for inclusion. The overall meta-analysis included 5877 participants and showed reductions in pain favouring exercise (standardised mean difference − 0.45; 95% confidence interval − 0.62, − 0.28). For most (> 82%) of the subgroup analyses, the direction of effect favoured exercise compared with usual care, with effect sizes ranging from small to large (median effect size − 0.35; range − 0.03 to − 1.17). The overall strength of evidence for the effect of exercise on cancer-related pain was very low.

Conclusion
The findings provide support that exercise participation does not worsen cancer-related pain and that it may be beneficial. Better pain categorisation and inclusion of more diverse cancer populations in future research would improve understanding of the extent of benefit and to whom.

Analysis and verification of stress and plastic zone in surrounding rocks of hydraulic flushing borehole based on strain-softening

AbstractThis study aimed to solve the problem ignored by previous research on hydraulic flushing gas extraction technology regarding the strain-softening of surrounding rock. Firstly, through the analysis of experimental data, previous studies have proved that the essence of strain-softening is that the internal friction angle remains unchanged while the cohesion decreases. According to the variation law of cohesion of surrounding rocks in a borehole, we theoretically analyzed the stress distribution of the surrounding rock considering strain-softening and determined the theoretical formula of the plastic zone radius. Subsequently, we established a numerical calculation model considering strain-softening using the COMSOL numerical simulation software. We simulated the influence of residual cohesion on the stress and plastic zone of surrounding rocks of the borehole. We found that with the decrease in residual cohesion, the peak stress transferred to the deep and the plastic zone radius gradually increased. The simulation results were compared with the theoretical values, and the errors were found to be within 10%, which verifies the model's accuracy. Subsequently, we studied the influence law of strain-softening on the stress and plastic zone of surrounding rocks of boreholes with different radii. We found that the larger the borehole radius, the greater the influence of strain-softening. The field measurement results show that the stress reduction zone of a hydraulic flushing borehole is about 10 times the borehole radius. The stress reduction zone calculated without considering strain-softening is 1.305 times the borehole radius, and that calculated while considering strain-softening is 6.663 times the borehole radius. Thus, we proved that strain-softening is an essential factor affecting the stress distribution of surrounding rocks of the borehole. When studying the gas extraction through a hydraulic flushing borehole, it is necessary to consider the strain-softening of surrounding rocks.
Analysing of the sustainable development goals in Damascus University during Syrian crisis using the strategy in the university and the bibliometrics data from SciVal
Authors: Al-Raeei Marwan 
Published: May 2023

AbstractMost countries strive to reach effective sustainable development policies, given the repercussions of this policy on many aspects, such as the economic growth of countries. The adoption of policies of sustainability by developing countries may lead to their development faster than expected. This research aims to study the strategies applied in one of the universities of developing countries and the sustainability policies adopted at that university which is Damascus University. The study focuses on the time during last four years of the Syrian crisis through several factors, with a focus on the analysis based on the SciVal and Scopus databases and the strategies applied by the university itself. In this research, we use the method of extracting and analysing the data of the sixteen sustainable development goals (SDGs) of Damascus University within Scopus and SciVal. We also analyse the strategies used in the university in order to reach some of the determinants of SDGs. By analysing Scopus and SciVal data, we find that the third goal of SDGs is the most widespread in terms of scientific research in Damascus University. We find that the application of such policies led to an important goal in the environment, which is the ratio of green space in Damascus University reaching to more than 63 percent of the total flat area of the university. In addition, we find that the application of sustainable development policies led to the generation of energy from renewable sources by 11% of the total electrical energy consumed at the university. The university has been able to reach lots of indicators of the sustainable development goals and it remains apply others.
Sedimentary records reveal two stages of evolution of the Abandoned Yellow River Delta from AD1128 to AD1855: vertical accretion and land-forming

Published: May 2023

AbstractIn AD1128, the Yellow River shifted its course from the Bohai Sea to the South Yellow Sea (SYS) due to anthropogenic dike excavation, starting the development of the Abandoned Yellow River Delta (AYRD) that lasted for more than 700 years (AD1128-1855). However, the sediment flux of the abandoned Yellow River into the sea is in a state of change due to human activities, and the growth process of the AYRD is not well understood. Here, we investigate the growth process of the AYRD and its sedimentary record characteristics over the last millennium based on three cores collected from the AYRD.The results show that the main sediment types in the AYRD are silt, mud and sandy silt. After AD1128, the grain size components in the sediments of the AYRD showed significant stage changes with the sand content first starting to decrease. The clay content increased and remained at a high percentage in the middle to late 14th century, followed by a sharp increase from the mid-16th to the mid-17th century, due to a further increase in sediment flux from the abandoned Yellow River into the sea. A slight increase in the proportion of sand content during the final stage of the transition from subaqueous delta to terrestrial delta is a distinctive feature of the sedimentary record, and this change persists for 10 ~ 90 years in different core records.This study further proposes a schematic model of the development of the AYRD: (a) before the 16th century, the sediments were deposited mainly in the estuary and nearshore, with rapid vertical accretion; (b) After the 16th century, the horizontal land formation was the main focus, and the rate of seaward extension increased rapidly. This model also reflects the following pattern: when the sediment flux from the river into the sea is certain, the rate of land formation is inversely proportional to the rate of vertical accretion. The dominant factors affecting the evolution of the AYRD are the sediment flux into the sea and initial submerged topography, with less influence from sea level changes. Hydrodynamic erosion by wave and tidal forces from the outer delta began to dominate after the interruption of sediment supply due to the Yellow River mouth northward to the Bohai Sea in AD1855. This study has important implications for understanding the growth and evolution of deltas under the influence of human activities.
Using video detection of snow surface movements to estimate weak layer crack propagation speeds

Published: May 2023

Abstract
Dry-snow slab avalanches release due to crack propagation in a weak snow layer under a cohesive snow slab. Crack propagation speeds can provide insights into the potential size of avalanches and inform fracture and avalanche release models. Despite their importance, slope-scale crack speed measurements from real avalanches are limited. Further, most existing slope-scale measurements utilize the appearance of slab fractures on the snow surface. However, we have no evidence that the appearance of surface cracking is a good indicator of the weak layer crack propagation tip. Here we present a novel method to estimate crack propagation speed from snow surface movements in avalanche videos. Our technique uses changes in frame pixel intensity, allowing us to detect the location of weak layer cracks well before slab fractures appear on the snow surface. We use field experiments and numerical simulations to validate our method before applying it to five avalanches. Our estimates show that cracks propagate faster up and down the slope than in the cross-slope direction; this suggests that different propagation regimes likely govern crack propagation up/down the slope, cross-slope and in flat terrain.
The Impact of Digitalization on International Investment Law: Are Investment Treaties Analogue or Digital?
Authors: Polanco Rodrigo 
Published: May 2023

AbstractThis article explores digitalization’s impacts on the existing international investment law regime. In particular, it examines whether international investment agreements (IIAs) apply to the digital economy, analyzing their scope of application, including the definition of protected investment and protected investor, as well as the territorial application of those treaties. We conclude that the IIAs and their provisions are, in principle, not intended for the digital era. However, their usually broad definitions are likely to cover investments in digital assets, if there is a flexible interpretation of the required territorial nexus. However, we believe caution should be exercised about including digital transformation commitments in IIAs, as they could increase the chance of investor-state dispute settlement (-ISDS-).
ASSESSING THE SPREAD OF ENEOLITHIC AGRICULTURAL COMMUNITIES IN THE FOREST-STEPPE OF UKRAINE USING AMS RADIOCARBON DATING

Published: May 2023

ABSTRACTCurrent scholarship suggests that Neo-Eneolithic systems of settlement and subsistence in Eastern Europe were defined by short-to-medium range migration, while sparsely populated land in peripheral regions allowed for the continual colonization of new territories. We address the Eastern Tripolye Culture (ETC), a sub-group of the Cucuteni-Tripolye cultural complex that flourished ca. 4300–2950 BC by expanding into the forest-steppe ecozone of Central Ukraine. While a general lack of multi-layer sites complicates regional chronology, we resolve several longstanding questions in Ukrainian archaeological discourse by combining traditional relative chronologies of ceramic types with high-precision AMS dating of material from key sites. We offer a revision of the chronology of Tripolye BI and BI-II, which, rather than consisting of distinct “early” and “late” temporal periods, instead constitute a single period characterized by stylistic diversity in material culture. With an absolute chronology established, we then analyze the space-time distribution of sites, revealing a southwest-to-northeast migratory vector across Central Ukraine characterized by punctuated episodes of “leapfrog” colonization. The establishment of this vector by the ETC presages larger-scale population movements by the Western Tripolye Culture (WTC), which led to the establishment of the giant-settlement phenomenon during the first part of the 4th millennium BC.
Canada's Federal Electoral Districts, 1867–2021: New Digital Boundary Files and a Comparative Investigation of District Compactness
Authors: Taylor Zack , Lucas Jack , Kirby J. P. , Hewitt Christopher Macdonald 
Published: May 2023

AbstractWe introduce new data resources to enable spatial and nonspatial research on Canadian elections, electoral history and political geography. These include a comprehensive set of distinct identification codes for every federal electoral district in Canada from 1867 to the present, a complete set of digital boundary files for these electoral districts, historical census data aggregated to federal electoral districts, and tools to connect our district identification codes to federal election results. After describing the construction and content of these new resources, we provide an example of their use in a comparative-historical analysis of district compactness in Canada and the United States. We find that, in contrast to the United States, postwar institutional changes to district boundary-drawing processes had little effect on district compactness in Canada.
