AbstractThis is a systematic review and meta-analysis that assessed the impact of performing OAGB with a 150-cm BPL versus a 200-cm BPL concerning weight loss, comorbidities remission, and adverse nutritional effects. The analysis included studies that compared patients who underwent OAGB with a 150-cm BPL and 200-cm BPL. Eight studies were eligible for this review after searching in the EMBASE, PubMed central database, and Google scholar. The pooled analysis revealed favoring the 200-cm BPL limb length for weight loss, with a highly significant difference in the TWL% (p=0.009). Both groups showed comparable comorbidities remission. Significantly higher ferritin and folate deficiency rates were found in the 200-cm BPL group. Considering a 200-cm BPL when performing OAGB delivers a better weight loss outcome than a 150-cm BPL, which is at the expense of a more severe nutritional deficiency. No significant differences were found regarding the comorbidities’ remission.

Published: April 2023

AbstractThe capability of wire and arc additive manufacturing (WAAM) to produce large, near-net-shaped parts with inexpensive equipment has led to the process being considered as one of the options to significantly decrease the buy-to-fly ratio in aircraft manufacture. Even so, there are several challenges associated with the process: achieving mechanical properties and microstructure similar to wrought material, as well as the low surface quality of the parts. The low surface quality is usually improved by milling. As with the microstructure, here too the question arises as to whether the process is comparable to milling wrought material. A significant factor influencing the microstructure according to literature is the interlayer temperature during the WAAM process. Therefore, the objective of this research was to study the influence of the interlayer temperature on the machinability and the microstructure of wire and arc additively manufactured Ti-6Al-4V. Consequently, the machinability was first determined for Ti-Al6-V4-parts manufactured with three different interlayer temperatures. Then, the macro- and microstructures were analyzed and, finally, the mechanical properties were determined. Contrary to expectations based on the state of the art, the machinability was not influenced by the interlayer temperature. This aligns with the mechanical properties and the macro- and microstructures, which are only slightly affected by the interlayer temperature.

AbstractSecondary diabetes mellitus (DM) is a common complication of acromegaly, encountered in up to 55% of cases. Vice versa, the prevalence of acromegaly is markedly higher in cohorts of patients with type 2 DM (T2DM). The presence of secondary DM depends primarily on acromegaly status and is associated with increased cardiovascular morbidity, malignancy rate and overall mortality. The principal pathophysiologic mechanism is increased insulin resistance due to excessive lipolysis and altered fat distribution, reflected at the presence of intermuscular fat and attenuated, dysfunctional adipose tissue. Insulin resistance is ascribed to the direct, diabetogenic effects of growth hormone (GH), which prevail over the insulin-sensitizing effects of insulin-like growth factor 1 (IGF-1), probably due to higher glucometabolic potency of GH, IGF-1 resistance, or both. Inversely, GH and IGF-1 act synergistically in increasing insulin secretion. Hyperinsulinemia in portal vein leads to enhanced responsiveness of liver GH receptors and IGF-1 production, pointing towards a mutually amplifying loop between GH-IGF-1 axis and insulin. Secondary DM occurs upon beta cell exhaustion, principally due to gluco-lipo-toxicity. Somatostatin analogues inhibit insulin secretion; especially pasireotide (PASI) impairs glycaemic profile in up to 75% of cases, establishing a separate pathophysiologic entity, PASI-induced DM. In contrast, pegvisomant and dopamine agonizts improve insulin sensitivity. In turn, metformin, pioglitazone and sodium-glucose transporters 2 inhibitors might be disease-modifying by counteracting hyperinsulinemia or acting pleiotropically. Large, prospective cohort studies are needed to validate the above notions and define optimal DM management in acromegaly.

ZusammenfassungSchulabsentismus wird vornehmlich als illegitimes Fernbleiben von der Schule und damit als individuelles Fehlverhalten diskutiert. Demgegenüber nimmt der vorliegende Beitrag einen Blickwinkel auf das Phänomen ein, der stärker die Bedeutung schulischer Strukturen und Praktiken für den Schulabsentismus akzentuiert. Der Beitrag plädiert für eine machtanalytische Perspektive auf den Gegenstand und dafür, den Schulabsentismus als etwas zu verstehen, das auch in und durch schulische Machtverhältnisse hervorgebracht wird.
Can Māori Negotiate School Attendance in State-Led Education in Aotearoa, New Zealand?
Authors: Coulter Sarah-Kay 
Published: April 2023

AbstractThere is a conflict between the claims of Māori sovereignty and the imposition of State legislation on Māori children. This conflict of interest has been given very little consideration in the public sphere. This research-informed article speculates that despite legislation ensuring that education attendance is fixed as a legal obligation for all Primary and Secondary aged children, there is urgency to address if conceivably this is a deeply flawed assumption as it contradicts notions of tribal sovereignty. Cautiously, this article does not romanticise past positioning of Māori peoples, nor makes claims to indigenous righteousness, rather moves to suggest that State-led education belongs part of positive outcomes for Māori, however there must be negotiation to the terms and expectations for education attendance. This paper is a catalyst for future orientated discussion aiming to broaden what education can move to become in Aotearoa, New Zealand.

Published: April 2023

AbstractBased on the fact that the production of deep coalbed methane (CBM) in Yushe-Wuxiang Block is lower than expected, the paper is carried out uniaxial strength test and triaxial rheological test on coal measure strata reservoirs (mudstone, coal, sandstone and their composite sample) deeper than 1300 m in the block. In the uniaxial strength test, it is found that the stress–strain process of deep coal rock sample was similar to that of shallow one. The brittleness of deep coal rock sample is more obvious. It can also serve as described by the four stages of shallow coal rock sample in the compression process. The compressive strength of the coal in the combined samples will be improved in a small range, while the mudstone will be driven to produce radial tensile failure at the moment of failure. Creep characteristics of the composite sample are similar to those of the single one, and the axial deformation characteristics under lower stress (14 MPa, 18 MPa, 22 MPa) are close to those of coal. The axial deformation characteristics under extreme stress (26 MPa, 30 MPa, 34 MPa) are close to those of sandstone. The established stress-seepage coupled creep damage model can be used to describe the deformation law of each rock sample under different stresses. The permeability characteristics of the composite sample are determined by the poor permeability of the composite formation. There is a great correlation between the volume deformation and permeability evolution of the sample in the test. The permeability model based on the theory of porous media can be well fitted the relationship between volumetric strain and permeability. It is of great significance to predict the influence of creep effect on permeability under different in-situ stresses in engineering.

AbstractIn the High Modernism period, from around 1914 to 1970, many system halls in steel construction were manufactured to meet the increasing demand in industry, commerce, and agriculture, among other areas. However, these types of buildings have not been the focus of any research in the field of construction history, generating a lack of knowledge regarding their construction types, distribution, and related context to enable statements on the ability and worthiness of historical monument listings. This paper proposes a methodology for the automatic detection of these buildings using aerial imagery. For this purpose, Deep Learning techniques for two tasks are evaluated: semantic segmentation and object detection. Different state-of-the-art software architectures are extensively reviewed and assessed through a series of experiments to determine which features and hyper-parameters produce the best results. Based on our experiments, the height information from nDSM improved the results by refining the detections and reducing the number of false negatives and false positives. Moreover, the Focal Loss helped boost the detections by tuning its hyper-parameter $$\gamma$$

Networks of splicing processors: simulations between topologies
Authors: Martín José Angel Sanchez , Mitrana Victor , Păun Mihaela 
Published: April 2023

AbstractNetworks of splicing processors are one of the theoretical computational models that take inspiration from nature to efficiently solve problems that our current computational knowledge is not able to. One of the issues restricting/hindering is practical implementation is the arbitrariness of the underlying graph, since our computational systems usually conform to a predefined topology. We propose simulations of networks of splicing processors having arbitrary underlying graphs by networks whose underlying graphs are of a predefined topology: complete, star, and grid graphs. We show that all of these simulations are time efficient in the meaning that they preserve the time complexity of the original network: each computational step in that network is simulated by a fixed number of computational steps in the new topologic networks. Moreover, these simulations do not modify the order of magnitude of the network size.
Pilot scale evaluation of thin film composite membranes for reducing wastewater volumes: osmotic concentration process

Published: April 2023

AbstractGas operations generate large volumes of wastewater, necessitating efficient water management schemes. This study evaluates a forward osmosis (FO) pilot plant for volumes reduction of gas industry process water (PW). The osmotic pressure difference between seawater (40 g/L Total Dissolved Solids (TDS)) and low salinity (2 g/L TDS) PW is used for the osmotic concentration (OC). In the OC, PW volumes get reduced, while diluted draw solution (DS) is directly discharged, obviating the high-energy DS recovery step. A thin-film composite hollow fiber (HF) FO membrane was tested under FO mode using synthetic solutions to assess the performance on the OC unit. Subsequently, the pilot unit was subjected to PW feed for 48 h of continuous operation, primarily to evaluate water flux, reverse solute flux (RSF), and membrane fouling. The cleaning requirement to remove contaminants from the membrane surface was examined. The membrane achieved a water flux and RSF between 11.5 to 6.43 LMH and 38.57 to 9.45 mmol h−1 m−2, respectively at feed recovery rates between 60 and 90%. The membrane achieved a water flux of 10 LMH, which slightly decreased to 9.6 after 48 h of operation, mainly due to inorganic scaling. Lastly, cleaning with citric acid succeeded in recovering the initial water flux.
Unveiling the synergistic effect of internal Fe single atoms and introduced Fe3C in Enteromorpha derived biochar with enhanced peroxymonosulfate activation property towards nitenpyram removal
Authors: Xiong Sheng , Zeng Hao , Deng Yaocheng , Tang Rongdi , Wang Jiajia , Li Ling , Zhou Zhanpeng , Gong Daoxin 
Published: April 2023

AbstractThis work demonstrated that Enteromorpha biochar with introduced iron (SFB900-3) could activate peroxymonosulfate (PMS) efficiently for NTP remediation. It removed 83.9%–95.1% of NTP in 60 min under a wide pH range from 3.15 to 8.95. Density functional theory (DFT) calculations revealed the synergistic relationship between internal Fe single atoms and introduced Fe compounds—Fe3C. The adsorption capacity of SFB900-3 for persulfate improved from −0.953 eV to −4.214 eV, and the Bader charge analysis showed that Fe atoms as active sites (0.658 e) enhanced the adsorption capacity more than carbon (0.050 e). Moreover, the energy barrier for PMS dissociation reduced from 0.072 eV to −5.372 eV due to the longer length of O–O bond under the synergistic effect of Fe single atom and Fe3C which increased from 1.467 Å to 3.890 Å. The quenching experiment confirmed that 1O2 was the main active substance in NTP degradation and its contribution rate was 88.2%, which was further verified by EPR detection. The effect factor experiments proved that the SFB900-3/PMS system had stable and efficient activity for NTP removal, which remained at 73.6% removal rate after three rounds of tests. This work provided novel guidance for constructing efficient and stable biochar-based materials for organic pollutant remediation.

Sustainable energy propulsion system for sea transport to achieve United Nations sustainable development goals: a review
Authors: Tay Zhi Yung , Konovessis Dimitrios 
Published: April 2023

AbstractThe cost of renewable energy technologies such as wind and solar is falling significantly over the decade and this can have a large influence on the efforts to reach sustainability. With the shipping industry contributing to a whopping 3.3% in global CO2 emissions, the International Maritime Organization has adopted short-term measures to reduce the carbon intensity of all ships by 50% by 2050. One of the means to achieve this ambitious target is the utilisation of propulsion systems powered by sustainable energy. This review paper summarises the current state of the adoption of renewable energy and alternative fuels used for ship propulsion. Special focus is given to the means of these alternative energies in achieving the United Nations Sustainable Development Goals, in particular Goal 7 (Affordable and Clean Energy), Goal 9 (Industry, Innovation and Infrastructure) and Goal 13 (Climate Action). A state-of-the-art for various ships powered by renewable energy and alternative fuels is investigated and their technologies for mitigating carbon emissions are described. The cost for each technology found in the literature is summarised and the pros and cons of each technology are studied.
Scalable flood inundation mapping using deep convolutional networks and traffic signage
Authors: Alizadeh Bahareh , Behzadan Amir H. 
Published: April 2023

AbstractFloods are one of the most prevalent and costliest natural hazards globally. The safe transit of people and goods during a flood event requires fast and reliable access to flood depth information with spatial granularity comparable to the road network. In this research, we propose to use crowdsourced photos of submerged traffic signs for street-level flood depth estimation and mapping. To this end, a deep convolutional neural network (CNN) is utilized to detect traffic signs in user-contributed photos, followed by comparing the lengths of the visible part of detected sign poles before and after the flood event. A tilt correction approach is also designed and implemented to rectify potential inaccuracy in pole length estimation caused by tilted stop signs in floodwaters. The mean absolute error (MAE) achieved for pole length estimation in pre- and post-flood photos is 1.723 and 2.846 in., respectively, leading to an MAE of 4.710 in. for flood depth estimation. The presented approach provides people and first responders with a reliable and geographically scalable solution for estimating and communicating real-time flood depth data at their locations.
The incidence and prognostic role of β-catenin and E-cadherin biomarkers in bladder neoplasms, a cross-sectional study
Authors: Yazdi Seyed Amir Miratashi , Batmani Sara , Tabriz Hedieh Moradi , Nazar Elham , Pourebrahimi Elham 
Published: April 2023

Abstract

Objectives
To predict the aggressive behavior of the bladder tumor as well as the poor prognosis of the disease, the use of some biomarkers including β-catenin and E-cadherin related to the detachment of tumoral cells from its primary lesion can be very beneficial. We intended to evaluate the incidence of β-catenin and E-cadherin expression and their association with tumor biological behavior in patients suffering bladder neoplasms.

Methods
This cross-sectional study was done on 30 established bladder neoplasms on tissue assessment with evidence of malignancy on cystoscopic examination. Hematoxylin and Eosin stains were planned for pathological evaluation in terms of tumor biological behavior. Immunohistochemistry staining for two markers E-cadherin and β-catenin was done to evaluate gene expression.

Results
Overall, β-catenin biomarker was expressed in nuclear in only one patient (3.3%), while abnormal E-Cadherin staining was revealed in none of the patients. The expression of these biomarkers was independent of tumor characteristics including vascular invasion, tumor size, tumor grade, and tumor stage (P-value>0.05).

Conclusion
The change in β-catenin and E-cadherin expression probably has a weak prognostic role in the prediction of the biological behavior in bladder neoplasms as well as the clinical outcomes of patients in our society.

Published: April 2023

Introduction Wilderness medicine education is one of the fastest growing facets of both graduate and undergraduate medical education. Currently, there are curriculum guidelines for both student electives and fellowships in wilderness medicine. However, there are no guidelines for resident elective curricula. The student/resident education committee of the Wilderness Medical Society (WMS) convened a task force to develop curriculum guidelines for these electives. Methods A survey of previously described core wilderness medicine topics was sent to a cohort of educators involved in wilderness medicine resident electives. They were asked to rank topics on the basis of their importance of being included on a Likert scale. Multivariate analysis of medians was used to distinguish among topics to determine which topics were voted most and least necessary for a curriculum. Results Of the database members contacted, 35 responded to the survey. The described current state of residency electives was that 16 institutions offered their own elective (46%). For subject preferences, multivariate analysis of scoring distribution medians demonstrated a significantly higher pattern of responses ( P<0.01) for subjects with a median of 3 (must include) than for the lowest-scoring subjects that had a median of 1 (can include). Every topic was rated “must” by at least 1 respondent. Topics were further subdivided into an educational framework reflecting a common approach to education of wilderness medicine fellows focusing on education, leadership, knowledge, and skills. Conclusions There was a wide variety in the ranking of topics; however, there were multiple topics on which a consensus for inclusion was reached. These topics are organized and presented here as a suggested curriculum by the student/resident education committee of the WMS.
Structure and Dynamics of Lithosphere and Asthenosphere in Asia: A Seismological Perspective
Authors: Ma Jincheng , Bunge Hans‐Peter , Fichtner Andreas , Chang Sung‐Joon , Tian You 
Published: April 2023

AbstractKnowledge of lithospheric structure is essential for understanding the impact of continental collision and oceanic subduction on surface tectonic configurations. Full‐waveform tomographic images reveal lateral heterogeneities and anisotropy of the lithosphere and asthenosphere in Asia. Estimating lithospheric thickness from seismic velocity reductions at depth exhibits large variations underneath different tectonic units. The thickest cratonic roots are present beneath the Sichuan, Ordos, and Tarim basins and central India. Radial anisotropy signatures of 11 representative tectonic provinces uncover the different nature and geodynamic processes of their respective past and present deformation. The large‐scale continental lithospheric deformation is characterized by low‐velocity anomalies from the Himalayan Orogen to the Baikal rift zone in central Asia, coupled with the post‐collision thickening of the crust. The horizontal low‐velocity layer of ∼100–300 km depth extent below the lithosphere points toward the existence of the asthenosphere beneath East and Southeast Asia, with heterogeneous anisotropy indicative of channel flows.
