Modeling of crustal layering using three-dimensional analysis of stress-drop slip zones in an elastic layer/half-space system
Authors: Wu M. , Sakae C. , Keer L. M. 
Published: February 2023

AbstractA numerical scheme for calculating the elastic fields in a layer over a half-space medium due to embedded slip zones of prescribed stress drop was developed to examine how the layer influences fault mechanics. Although the method is general, for simplicity, only penny-shaped slip zones were considered in the current analysis. For slip zones that are embedded in the half-space and near the interface, it was found that the layer causes the slip to depart from that for a uniform medium: softer layers tend to increase, but stiffer layers tend to decrease the magnitude and gradient of the slip near the upper end of a slip zone. Consequently, the layer causes an increase, if the layer is softer, or a decrease, if the layer is stiffer, in the energy release rate of the slip zone. The layer was also seen to have a strong effect on the surface displacements to the extent that the distance change predicted between a pair of stations across the slip zone could be biased by a uniform half-space model. The results also showed that the layer can cause a significant change in the uniform normal stress, which can alter the frictional resistance.

The use of enzyme preparations is a traditional trend in various fields of medicine. The usage of immobilized enzymes hyaluronidase (IG) and subtilisin (IS) seems to be very promising for the treatment of damage to the ocular surface. The aim of the study was to establish the nature of changes in the ultrastructural organization of human conjunctival epithelium under the influence of immobilized hyaluronidase and subtilisin in vitro. Material and methods. In the experiment, a culture of normal cells of the human conjunctiva Chanqconjunctiva, clone 1–5 C-4, was seeded in 96well plates in the amount of 2 × 104 cells/well, after 24 h the medium was removed, Eagle’s medium MEM and fetal calf serum were added and cells were cultured for another 48 h. 5 experimental groups were formed: group 1 – without drugs (except for the composition of the incubation scheme), groups 2 and 3 – with IS at a concentration of 37 and 150 U/ml, respectively, groups 4 and 5 – with IG at a concentration of 37 and 150 U/ml, respectively. After preparation of cell preparations under a JEM 1400 electron microscope (Japan), ultrathin sections of 70–100 nm were studied at ×1000 magnification. Results. The article presents the results of electron microscopy of a culture of normal cells of the human conjunctiva in 5 experimental groups of cells with a description of changes in cytoarchitectonics under the influence of IG and IS. Conclusions. The introduction of immobilized enzymes into human conjunctival cell culture at a low dose (37 U/ml) affects the organization of cells without cytotoxic effects, while increasing the dose directly correlates with the occurrence of a cytotoxic effect.

Statistical stegdetectors performance by message re-embedding
Authors: Progonov Dmytro 
Published: February 2023

State-of-the-art stegdetectors for digital images are based on pre-processing (calibration) of analyzed image for increasing stego-to-cover ratio. In most cases, the calibration is realized by image processing with enormous set of high-pass filters to obtain good estimation of cover image from the stego one. Nevertheless, the efficiency of this approach significantly depends on careful selection of filters for reliably extraction of cover image alterations that are specific for each embedding method. The selection is non-trivial and laborious operation that is realized today by training of convolutional neural networks, such as Ye-Net, SR-Net to name but a few. The paper is devoted to performance analysis of alternative approach to image calibration, namely message re-embedding into analyzed image. The considered method is aimed to increasing stego-to-cover ratio by amplification of cover image alterations caused by message hiding. The analysis was performed on ALASKA and VISION datasets by usage of stegdetector based on SPAM model of covers. Messages were re-embedded according to state-of-the-art adaptive methods HUGO, S-UNIWARD, MG and MiPOD. Proposed approach allows significantly (up to 20%) decreasing detection error even in case of low payload of cover image (less than 10%) where modern stegdetectors are ineffective.

Published: February 2023

The task of assessing the destructive effects on information is considered public safety on the example of electoral losses in the process of information opposition. To find a solution to the above problem, it is proposed a non-linear model based on process modeling pre-election races. Based on similar studies, it was the impact of destructive informational influences on certain security is considered layers of society. A case study where an adversary advances its narratives for capture of a part of society in its information field, as well as his keeping under its influence at the expense of existing agents. For this purpose he involves influence agents who act in two groups. For the specified situation it was the process of transition of the electorate to the information environment is simulated opponent.
The following groups of objects were considered in the model: our agents, which functionally, they only oppose the agents of the adversary, groups of society, divided according to the possible impact on them, and two groups of agents enemy, each of which can change as a result of losses and necessity keeping under its influence members of the social groups that reacted positively on the information narratives of the adversary. As a result, the simulation was carried out assessment of probable electoral losses, which provides grounds for determination optimal counteraction to destructive informational influences.

Published: February 2023

To identify and classify objects on images obtained using UAV imaging and orbital-based imaging, a neural network classification model based on the use of an autoencoder and built on the architecture of an ensemble of multilayer perceptrons is proposed. Additionally, at the stage of highlighting informative features, is added a color information, which is based on the per-channel histograms and is invariant to the scale and rotations of the image. The model is implemented using the Keras library. The use of the proposed model for classification into four classes: “Fire”, “Smoke”, “Vegetation” and “Buildings”, allows to achieve a classification accuracy above 99%.

Abstract
Background

Insulin pump therapy (IPT) improves glucose control in people with Type 1 diabetes (T1D) compared with multiple daily injections (MDI). However, their size, the tethered insulin infusion set, intrusiveness when operating the device, and the need to disconnect during showering limits their acceptance to many who may benefit. The Omnipod DASH® Insulin Management System is a small waterproof tubeless device worn on the upper arm which is wirelessly controlled by a handheld device which may be an acceptable alternative. However, there are no randomised controlled trials focusing on the impact on user perceptions of tubeless insulin pump therapy. This pilot study aims to assess the acceptability and feasibility of patch pump therapy compared with usual care in adults with T1D in Australia.

Methods

A pilot multi-site parallel randomised controlled study will be conducted in sixty-four adults with T1D who are managed on MDI or IPT and self-monitoring with finger-stick blood glucose from four specialist diabetes centres in Victoria, Australia. Following carbohydrate counting education, participants will be randomised to use Omnipod DASH® System (Omnipod group) or continue usual care (Usual care group) for 12 weeks, followed by a 12-week extension phase where all participants will use Omnipod DASH® System. The primary study outcome measures are acceptability which will be assessed by the difference in Diabetes Technology Questionnaire “current” (DTQ-current) score at 12 weeks post-randomisation compared to baseline, and feasibility which will be evaluated through study completion rates. Data on process outcomes, resource outcomes, participant centred outcomes, healthcare professional perceptions and glycaemic outcomes will also be collected.

Discussion

This pilot study will provide insights regarding feasibility of the study design and first data regarding user acceptance of insulin patch pump technology in Australian T1D adults. We anticipate that this study will provide information informing the design of a larger study evaluating the impact of patch pumps on subjective outcomes that are of significance to the person living with T1D.

Diurnal water fluxes and growth patterns in potato tubers under drought stress
Authors: Huntenburg Katharina , Pflugfelder Daniel , Koller Robert , Dodd Ian C. , Dusschoten Dagmar van 
Published: February 2023

Abstract
Background and Aims: Potato tubers comprise 83 % water at harvest, but surprisingly few studies address tuber water relations in drying soil. This study aims to understand whether soil drying alters water tuber fluxes and their effect on tuber volume growth.
Methods: tuber water content and volume growth were investigated every 4 hours using magnetic resonance imaging (MRI) during soil drying and re-watering, with leaf gas exchange, leaf water potential and foliar abscisic acid (ABA) concentration measured concurrently.
Results: Tubers of well-watered plants showed a diurnal growth pattern with their volume andaverage water content (TWC) increasing overnight. Withholding irrigation caused typical shoot drought stress responses (e.g. stomatal closure), dampened fluctuations in total TWC and paused nocturnal volume growth. Irrespective of soil moisture, tubers lost water (likely to the shoot) during the daytime when the plant transpires, while tuber water loss to the soil was minimal. Re-watering restored tuber volume growth and average TWC due to root water uptake and transport to the tuber.
Conclusions: Potato tubers can supply water to the shoot. Nocturnal water influx needs to exceed daytime water efflux for net tuber volume growth, which should be considered in irrigation management.
Estimation of the genetic influence on bone mineral density for Japanese women: a twin study

Published: February 2023

Abstract

Purpose
Although osteoporosis is a crucial problem in super-aged societies such as Japan, the heritability of bone mineral density in the Japanese population has not been studied to date.
Methods
Quantitative ultrasound was used to measure the bone area ratio (BAR, %) of 298 healthy, female Japanese twins (149 pairs, 136 monozygotic and 13 dizygotic twin pairs) registered in the Osaka University Twin Registry. Classical twin analysis was used to measure the heritability of bone mineral density.
Results
The heritability of bone mineral density for the group with all subjects was 0.51 (95% confidence intervals (CI) 0.38 – 0.63). For the group of subjects younger than 50 years, the effects of menopause were adjusted for and the best-fit model was also found to be the AE model, with a heritability estimate of 0.53 (95% CI: 0.34 – 0.72).
Conclusion
Japanese women appear to have a relatively lower heritability of bone mineral density compared with women from other countries. Therefore, environmental factors may play a significant role in the osteoporosis of Japanese women compared with women of other race and ethnicity.
A new method for interpreting well-to-well interference tests and quantifying the magnitude of production impact: Theory and applications in a multi-basin case study
Authors: Almasoodi Mouin , Andrews Thad , Johnston Curtis , Singh Ankush , McClure Mark 
Published: February 2023

Abstract
Interference tests are used in shale reservoirs to evaluate the strength of connectivity between wells. The results inform engineering decisions about well spacing. In this paper, we propose a new procedure for interpreting interference tests. We fit the initial interference response with the solution to the 1D diffusivity equation at an offset observation point. It is advantageous to use the initial interference response, rather than the subsequent trend, because the initial response is less affected by nonlinearities, time-varying boundary conditions, and uncertainties about flow geometry and flow regime. From the curve fit, we estimate the hydraulic diffusivity and the conductivity of the fractures connecting the wells. For engineering purposes, it would be useful to quantify the impact of interference on well production. Thus, we seek a relationship between the ‘degree of production interference’ (DPI) and an appropriate dimensionless quantity that can be derived from the estimate of fracture conductivity. Using simulations run under a wide range of conditions, we find that the classical definition for dimensionless fracture conductivity does not achieve a consistent prediction of DPI. This occurs because the dimensionless fracture conductivity was derived assuming radial flow geometry, but the dominant flow geometry during shale production is linear. We also find that the CPG (Chow Pressure Group) metric does not yield consistently accurate predictions of DPI. As an alternative, we derive a dimensionless quantity similar to the classical ‘dimensionless fracture conductivity,’ but which is derived for linear, not radial, flow geometry. Using this approach, we calculate a ‘dimensionless interference length’ that collapses all cases onto a single curve that predicts DPI as a function of fracture conductivity, well spacing, and formation properties. We conclude by applying the new method to field cases from the Anadarko and Delaware Basins.
Causes of stress and poor mental health in paramedicine students: A cross-cultural qualitative investigation in Saudi Arabia and the United Kingdom
Authors: Alzahrani Adnan , Keyworth Chris , Wilson Caitlin , Johnson Judith 
Published: February 2023

Abstract
Background: Paramedicine presents students with numerous challenges, including factors threatening their wellbeing. Over the last two decades studies have illustrated that paramedics and paramedic students are more likely to have mental disorders than the general population. These findings suggest that course-related factors could be important in contributing to poorer mental health. However, few studies have examined factors related to stress in paramedic students, and none of these have included paramedic students from cross-culture. To address this, the present study 1) explored paramedicine students' training experiences and other education-related factors that could affect their wellbeing, and 2) illustrated the possible differences and similarities between two cultures (Saudi Arabia and the UK) to determine whether the students’ cultural environment influenced factors related to their wellbeing.
Methods: A qualitative exploratory research design was used. Twenty semi-structured interviews were conducted with paramedicine students from the United Kingdom and Kingdom of Saudi Arabia (ten participants from each country). Reflexive thematic analysis was employed as the analytical approach in this study.
Results: Four major themes were identified which captured the contributors to paramedic students’ stress levels: 1) exposure to potentially traumatic events, 2) relationships and communication, illustrating the student's personal and professional experiences with others, 3) programme atmosphere, demonstrating the challenges and support students encounter during their coursework and training, and 4) career, elucidating the pressure of future career expectations and predictions.
Conclusion: The study revealed contributors to stress were similar in both countries. Better preparation can help to reduce the negative impacts of the possible traumatic events encountered on placements and supportive relationships, especially with proctors, can boost student wellbeing. Universities are able to address both these factors and help foster a positive environment for paramedicine students. As such, these results should help educators and policymakers when identifying and delivering interventions to support paramedic students.
