Published: December 2022

Abstract
Objectives Endoscopic mucosal resection (EMR) is useful for removing colon polyps and is generally carried out by one doctor. It is occasionally difficult for colorectal polyps to be removed by EMR. In such cases, EMR is performed by the main doctor and an assistant doctor (the two-person method). However, the efficacy and safety of EMR in the two-person method remain unclear. This study aimed to compare the procedure time and incomplete resection rate (IRR) by the two- and single-person methods of EMR for polyp removal.
Materials and Methods Data from colorectal polyps resected by EMR were reviewed retrospectively and divided into two groups: general procedure/single- (n = 215) or two-person method (n = 56). The IRR, the procedure time, and the incidence of adverse events were compared between these methods.
Results A total of 152 patients and 271 lesions were included in this study. The mean procedure time for polypectomy was significantly shorter in the two-person method group than in the general procedure group (median time: 3.38 minutes vs. 6.56 minutes; p < 0.001). Additionally, the IRR for polyps was significantly lower in the two-person methods group than in the single-person methods group (2/56, 3.6% vs. 47/215, 21.9%; p = 0.001). None of the patients in the two-person method group presented with delayed bleeding.
Conclusions The two-person method for EMR was more effective than the single-person method. Therefore, this method may replace the conventional one-operator method in the future.

Published: December 2022

Abstract
Aim/Objectives Duodenal varices (DVs), although rare, can present with massive, potentially fatal upper gastrointestinal bleeding; however, there are no randomized trials regarding management of this relatively uncommon presentation. We aim to report our experience with endoscopic cyanoacrylate glue injection in patients with DVs.
Materials and Methods We retrospectively evaluated the medical records of all patients with portal hypertension at our center between January 2010 and December 2021. Demographic characteristics along with the etiology, location, and effectiveness of cyanoacrylate glue injection for bleeding DVs were collected and analyzed.
Results A total of 5,892 patients with portal hypertension underwent endoscopy during the study period, of whom 41 patients (M:F = 29:12) with mean age of 38 years were noted to have DVs. While extrahepatic portal vein obstruction was the commonest etiology (n = 26), the most common site of DVs was the duodenal bulb (n = 21). Twenty-one (51%) out of these 41 patients presented primarily with DV bleeding and underwent endoscopic cyanoacrylate glue injection with successful hemostasis achieved of the index bleed; however, four of these 21 patients had rebleeding between 2 weeks and 12 months of follow-up requiring repeat endotherapy.. While three patients underwent successful repeat glue injections, one patient had recurrent massive bleedings, not amenable to endotherapy and was subjected to duodenal resection with surgical shunt procedure.
Conclusion While the prevalence of DVs in portal hypertension patients was 0.7% (41/5892), DVs accounted for 0.42% (21/4889) of portal hypertension-related bleedings. Endotherapy with cyanoacrylate glue appears to be a safe and cost-effective treatment for acute DV bleeding in a resource-limited setting.
Past, Present, and Future Perspectives of Plasminogen Activator Inhibitor 1 (PAI-1)
Authors: Morrow Gael B. , Mutch Nicola J. 
Published: December 2022

AbstractPlasminogen activator inhibitor 1 (PAI-1), a SERPIN inhibitor, is primarily known for its regulation of fibrinolysis. However, it is now known that this inhibitor functions and contributes to many (patho)physiological processes including inflammation, wound healing, cell adhesion, and tumor progression.This review discusses the past, present, and future roles of PAI-1, with a particular focus on the discovery of this inhibitor in the 1970s and subsequent characterization in health and disease. Throughout the past few decades diverse functions of this serpin have unraveled and it is now considered an important player in many disease processes. PAI-1 is expressed by numerous cell types, including megakaryocytes and platelets, adipocytes, endothelial cells, hepatocytes, and smooth muscle cells. In the circulation PAI-1 exists in two pools, within plasma itself and in platelet α-granules. Platelet PAI-1 is secreted following activation with retention of the inhibitor on the activated platelet membrane. Furthermore, these anucleate cells contain PAI-1 messenger ribonucleic acid to allow de novo synthesis.Outside of the traditional role of PAI-1 in fibrinolysis, this serpin has also been identified to play important roles in metabolic syndrome, obesity, diabetes, and most recently, acute respiratory distress syndrome, including coronavirus disease 2019 disease. This review highlights the complexity of PAI-1 and the requirement to ascertain a better understanding on how this complex serpin functions in (patho)physiological processes.
What drives health mindset and expectations in the United States?
Authors: Martin Laurie T. , Carman Katherine , Yeung Douglas 
Published: December 2022

AbstractHealth mindset is a group of beliefs or assumptions that individuals hold about the causes of health and well-being. Strengthening our understanding of factors that shape mindset and how mindset shapes expectations for who can and should be responsible for health can inform the success and sustainability of solutions to current health crises including the COVID-19 pandemic, ongoing disparities in health outcomes, and gun violence. We first examined associations between personal characteristics and experiences with health mindset. Next, we examined the association between mindset and the belief that government involvement can help address pressing health questions, using obesity as an example of a health outcome that is shaped both by personal choices and factors outside one’s control. Going forward, it will be important to consider health mindset in broader transformations of the health system and population approaches to improving health.
Information security risk management terminology and key concepts
Authors: Schmidt Michael 
Published: December 2022

AbstractLanguage is the foundation for any communication and the vocabulary used has a decisive influence on the ability of the communication partners to clearly understand each other. In Information Security Risk Management (ISRM), the terminology used is often dictated by industry standards and frameworks. However, there is no universally accepted terminology, which makes collaboration difficult for professionals and researchers alike. This publication compares the terminology defined by frequently used frameworks, such as ISO and NIST, in the field of ISRM. It examines the terms and inherent concepts of each terminology, compares the notion of risk and derives a concept diagram based on the most important key concepts. The result facilitates a common understanding of ISRM across frameworks and organisational boundaries, thus enables further research, discussion, intra- and inter-firm communication.

A rapid and accurate diagnostic modality is essential to prevent the spread of SARS-CoV-2. In this study, we proposed a SARS-CoV-2 detection sensor based on surface-enhanced Raman scattering (SERS) to achieve rapid and ultrasensitive detection. The sensor utilized spike protein deoxyribonucleic acid aptamers with strong affinity as the recognition entity to achieve high specificity. The spherical cocktail aptamers-gold nanoparticles (SCAP) SERS substrate was used as the base and Au nanoparticles modified with the Raman reporter molecule that resonates with the excitation light and spike protein aptamers were used as the SERS nanoprobe. The SCAP substrate and SERS nanoprobes were used to target and capture the SARS-CoV-2 S protein to form a sandwich structure on the Au film substrate, which can generate ultra-strong “hot spots” to achieve ultrasensitive detection. Analysis of SARS-CoV-2 S protein was performed by monitoring changes in SERS peak intensity on a SCAP SERS substrate-based detection platform. This assay detects S protein with a LOD of less than 0.7 fg mL−1 and pseudovirus as low as 0.8 TU mL−1 in about 12 min. The results of the simulated oropharyngeal swab system in this study indicated the possibility of it being used for clinical detection, providing a potential option for rapid and accurate diagnosis and more effective control of SARS-CoV-2 transmission.

Published: December 2022

Context The behaviours used by mammalian predators to track, kill, and consume prey are some of the most dynamic interspecific interactions in nature. However, they are often challenging to follow through the landscape and observe directly without disturbing the animals being watched. Aims We describe the behaviours used by wild dingoes while hunting macropods in Namadgi National Park, Australian Capital Territory, Australia. Methods Footage was initially captured by wildlife cinematographers on behalf of documentary programs and was made available for viewing after production. Hunting events were filmed from an altitude of >50 m by using a ‘long lens’ fitted to either a drone or helicopter. Results We recorded a suite of hunting behaviours that would have been extremely challenging to observe from the ground via traditional methods. This includes some of the first video records published in the scientific literature of the behaviours used by dingoes to hunt and kill macropod prey, as well as some rare observations of mother and pup hunting dynamics. We did not observe any signs of disturbance as a result of filming for either predator or prey. Conclusions The varied repertoire of predatory behaviours displayed by dingoes is similar to that documented in wolves and asserts them as a behaviourally complex top predator in the Australian landscape. In addition, we highlight the use of drones as a valuable approach for directly observing wild behaviours. They offer a minimally invasive and relatively inexpensive and accessible alternative to helicopters. This project is also a case study exemplifying the value of collaborations between filmmakers and researchers that enable the sharing of archival documentary footage for the study of wild animal behaviour. Implications Future studies of wild animal behaviour should consider employing drones (at a safe distance and in accordance with published best practices and guidelines) as an additional tool to collect types of data that would be challenging using other methods.
Near thermal-electric field controlled electrohydrodynamic 3D printing of high aspect ratio microstructures

Published: December 2022

Abstract
Electrohydrodynamic (EHD) printing is an effective method for high-resolution two-dimensional patterning because of its high material compatibility. The latest research on three-dimensional (3D) structure fabrication has been reported for metal nanoparticles, small molecular materials, and phase change materials by process regulation. One of the main challenges in conventional EHD 3D printing of polymers is the low accuracy of filament deposition and stacking at the microscale. It is difficult to achieve a high aspect ratio (AR) for printed structures. This study develops an external field-assisted EHD printing process for polymer materials, where the filament formation can be improved by the near thermal field and the stacking accuracy of filaments is further promoted by applying an alternating voltage between layers. The feasibility of this method is demonstrated by printing polystyrene, a typical polymer material, on the silicon substrate with. The regulatory effect of the process parameters on the filament width is explored. The influence of the external thermal field on filament formation and deposition is discussed, and a promotion mechanism is revealed of alternating voltage for accurate deposition. Based on these combinative effects, micro-scale 3D structures with a high AR are successfully printed on the insulating substrate with three kinds of polymers.

Investigation of the diameter-dependent piezoelectric response of semiconducting ZnO nanowires by Piezoresponse Force Microscopy and FEM simulations
Authors: Jalabert Thomas , Pusty Manojit , Mouis Mireille , Ardila Gustavo 
Published: December 2022

Abstract
Semiconducting piezoelectric nanowires (NWs) are promising candidates to develop highly efficient mechanical energy transducers made of biocompatible and non-critical materials. The increasing interest in mechanical energy harvesting makes the investigation of the competition between piezoelectricity, free carrier screening and depletion in semiconducting NWs essential. To date, this topic has been scarcely investigated because of the experimental challenges raised by the characterization of the direct piezoelectric effect in these nanostructures. Here we get rid of these limitations using the piezoresponse force microscopy technique in DataCube mode and measuring the effective piezoelectric coefficient through the converse piezoelectric effect. We demonstrate a sharp increase in the effective piezoelectric coefficient of vertically aligned ZnO NWs as their radius decreases. We also present a numerical model which quantitatively explains this behavior by taking into account both the dopants and the surface traps. These results have a strong impact on the characterization and optimization of mechanical energy transducers based on vertically aligned semiconducting NWs.

O3]0.7–[PbTiO3]0.3 (PMN-PT), however, the interplay between different coupling mechanisms is not yet well understood. To disentangle the role of strain and polarisation influence in Fe3O4/PMN-PT, we report on magnetoelectric coupling measurements for different orientations of the applied magnetic field and for two different substrate cuts, PMN-PT(001) and PMN-PT(011). For Fe3O4/PMN-PT(011), having the sample aligned such that the magnetic field is parallel to the [01

] easy axis leads to a remanent increase of the magnetisation for each electric field cycle. On the other hand, for the magnetic field along the [100] hard axis, the magnetisation follows a butterfly-like loop characteristic of strain coupling imparted by the substrate. For Fe3O4/PMN-PT(001), the magnetoelectric effect is a superposition of the observed behaviour of both in-plane directions in Fe3O4/PMN-PT(011). The magnetisation shows an initial remanent increase followed by a butterfly like loop. Polarised neutron reflectometry measurements on Fe3O4/PMN-PT(011) shows no difference between the behaviour at the interface and the bulk of the film and no decline of the interaction further away from the shared interface. Our results demonstrate the role of strain and polarisation on the magnetisation of the Fe3O4 layer and provide a clear step towards the design of future magnetoelectric systems.

Published: December 2022

Abstract
The general mathematical formulation of describing flows with chemical reactions problem includes mass conservation, momentum, energy and concentrations equations for each chemical substance, supplemented by the state equation and other thermodynamic relations. Chemical kinetics, through the heat of reactions, relates the concentrations of various substances to the energy equation. In many combustion systems, it is the chemical kinetics that determines the characteristic spatial and temporal scales of the equations to be solved. In this paper, we consider the problem of spray combustion of gaseous simple hydrocarbon fuel in a cylindrical channel. Mathematical modeling was carried out within the framework of the open package OpenFOAMv7, and the visualization of numerical results was carried out using Paraview 5.6. Deep understanding and tuning of a simple gaseous reaction scheme in the OpenFOAM package when modeling reacting flows is the goal of this work. It is shown that the CFD package used makes it possible to successfully simulate this class of flows.

Published: December 2022

Abstract
The material of the work is an integral element of the problem of determining the stress-strain state of various types of arrays, including various forms of recess. In the current problem, the stress state is determined in the plastic zone near an ellipsoidal recess for a compressible mass. There is no pressure inside the recess, and at a considerable distance there is compression by mutually perpendicular forces. A solution is obtained for the case of the first approximation by the small parameter method. The results can be applied in the field of structural mechanics, mining business, and other related fields.
An error analysis of a rheological study of magnetic nanofluids on a rotational viscometer
Authors: Bolotov A N , Novikov V V , Novikova O O 
Published: December 2022

Abstract
The paper considers metrological instrumentation for studying the rheological properties of magnetic fluids. It also presents the design of a magnetic coaxial viscometer. There is a metrological analysis of the factors that affect the measurement accuracy. Errors are systematized into 2 main groups: method and instrumental. The authors analyse the contribution of each group to the total metrological error. It is established that the temperature instability of the liquid under study and the error in determining the level of the liquid in contact with the measuring cylinder have the greatest effect on the measurement results. There is a theoretical assessment of the instrument error and its minimum value. The authors propose the main directions for improving the viscometer design. They also show the possibility of a significant reduce in the total measurement error by calibrating the device. There are comparative studies of experimental and reference liquids indicating good accuracy and reliability of experimental data.

Published: December 2022

Abstract
Converting a compression-ignition thermal plant to gas-liquid operation is one way to neutralize the danger of waste while maintaining the high efficiency of the engine corresponding to the original modification. Although debugging the functioning of a gas-liquid installation is a significantly problematic task, since we are dealing with a large number of interrelated properties. Therefore, optimizing the injection of diesel fuel (DF)/methane by solving a problem with several unknowns was one of the goals of our research. More than 10 parameters must be taken into account for the modeling to be adequate, including the initial (flammable) DF injection. In our experiments, the volume of the ignition DF was determined to be optimal in the amount of 0.15...0.20 relative to the single-fuel modification, respectively, the duration of fuel injection changed proportionally.
