Data-driven suppression of short-period multiples from laterally varying thin-layered overburden structures
Authors: Peng Haorui , Dukalski Marcin , Elison Patrick , Vasconcelos Ivan 
Published: November 2022

Marchenko multiple elimination methods remove all orders of overburden-generated internal multiples in a data-driven way. In the presence of thin beds, however, these methods have been shown to underperform. This is because the underlying inverse problem requires the information about short-period internal multiple (SPIM) imprint on the inverse transmission to be correctly constrained. This has been addressed in 1.5D media with energy conservation and minimum-phase reconstruction. Extending the applications to two dimensions and, hence, making the step toward field data were believed to be hampered by the need for a multidimensional minimum-phase reconstruction which is (1) not unique and (2) no algorithm has been found to perform this in practice on band-limited data. Here, we address both of these problems with an approach that includes solving the Marchenko equation with a trivial constraint, evaluating the energy conservation condition of its solutions to find the spatially dependent error syndrome, using the 1.5D minimum-phase reconstruction for each shot gather to find the spatially dependent constraint, and finally using that inside another run of the Marchenko equation solver to find a much-improved result. We find that the method works because in 2D media the expression of SPIMs in the inverse transmission coda is approximately 1.5D. We then investigate a class of models and synthetic data sets to verify where the 1.5D approximation starts breaking down. Our analysis indicates that this approach could perform very well in settings with moderate lateral variations, which also is where the (short-period) internal multiples are most difficult to differentiate from primary reflections.
Hidden hydrosphere under the Caspian Sea: Geophysical evidence and sea-level influence
Authors: Putans Victoria A. , Trimonova Mariia A. , Merklin Lev R. 
Published: November 2022

We analyzed geologic-geophysical data, both from archives and collections in recent expeditions by the Shirshov Institute of Oceanology of Russian Academy of Sciences, and revealed many anomalies in the seismoacoustic wavefield. Anomalies are of two types: horizontal disturbed layers and vertical pipes. Anomalies form associations — pipes (chimneys) are rooted in disturbed layers and go through sediments up to the seafloor and form pockmarks. We consider all specified seismic anomalies and bottom microrelief as a possibility of vertical migration of gas and water via sediments (fluid from sediments to water and from seawater to sediments). It is expected that the fluids form a huge underground hydrosphere below the Caspian Sea. To test the fluid flow, we made a mathematical model of fluid discharge and absorption in bottom sediments. We hypothesize that the Caspian Sea level fluctuates, at least partially, due to cycles of the submarine ground water discharge and sea water absorption back into the sediments. This cyclicity of fluid discharge and absorption correlates with regional seismic events. The earthquakes cause tectonic relaxation, triggering the absorption process, and sea-level drop due to reverse flow into sediments. In other periods, the tectonic tension causes sediment compression and fluid discharge to sea water, which causes sea-level rise. The model was tested on the recent (past 100 years) sea-level change curve. As a result, we got a distribution of the general volume of fluid flows depending on the infiltration coefficient. The real change in the Caspian Sea volume is at the lower range of the calculated values, so we cannot neglect the effect of “gas pipes” (“chimneys”) on the Caspian Sea-level change.
Design and implementation of a robust random number generator based on chaotic ring oscillators
Authors: Demir Kaya , Ergün Salih 
Published: November 2022

Abstract
In this paper, the design and implementation of a robust random number generator (RNG) based on chaotic ring oscillators is presented. The RNG output bits are generated through the chaotic sampling of chaotic waveform (CSCW) where the chaotic signals are obtained from two separate nodes of a chaotic ring oscillator (CRO). The proposed RNG is implemented on a FPGA (field-programmable gate array) combined with lumped elements on a breadboard circuit. The output bitstream of the proposed RNG passed the NIST 800-22 statistical randomness test suite without any need for post processing. To analyze the robustness of the CSCW method, a comparative analysis is conducted between chaos-based bit generation methods in terms of robustness against external interference. It is demonstrated that the proposed CSCW method ensures higher immunity of the RNG against external interference.
Glucagon-like Peptide-1 Receptor Agonist Treatment With Semaglutide in Type 1 Diabetes
Authors: Raven Lisa M , Greenfield Jerry R , Muir Christopher A 
Published: November 2022

Abstract
The efficacy of glucagon-like peptide-1 receptor agonists in type 2 diabetes is well established, but their role in type 1 diabetes (T1DM) is less clear. A 36-year-old woman with a 27-year history of T1DM and undetectable c-peptide presented for review of weight management, with body mass index 29.3 kg/m2. A previous trial of dapagliflozin led to no improvement in weight or glycemic control. Semaglutide was introduced (0.25 mg weekly increased to 0.5 mg weekly) and was well tolerated. After 6 months, weight had decreased by 16 kg and insulin dose by 36%. Despite less insulin, hemoglobin A1c improved, with reduced glycemic variability and no increase in hypoglycemia. Semaglutide may exert significant metabolic benefits in patients with established T1DM, even where c-peptide is no longer detectable. This case supports the need for a dedicated trial examining potential benefits of semaglutide in T1DM.
Selective Vapor-Phase Hydrogenation of Furfural to Furfuryl Alcohol over Cu/Silica Catalysts

Published: November 2022

Abstract
Vapor-phase hydrogenation of furfural (FAL) to furfuryl alcohol (FOL) was performed over 20 wt.% Cu supported on SiO2 under H2 pressure. The Cu/SiO2 catalyst with a pore size of 6 nm or larger provided FOL selectivity higher than 99% even at a high FAL conversion, whereas hydrogenolysis of FOL to 2-methylfuran (MF) proceeded over the Cu/SiO2 catalyst with small mesopores of 3 nm even at low FAL conversion. The selective transformation of FAL to FOL was regulated by the reaction temperature, H2 pressure, and contact time: the high FOL selectivity was achieved by minimizing the stepwise hydrogenolysis of FOL to MF, which is favorable under severe conditions. Under the optimum conditions, the FOL productivity was 3.1 kgFOL kgcat−1 h−1 with a FOL selectivity above 99% at 150 °C and an H2 pressure of 2.0 MPa. Furthermore, the Cu/SiO2 catalyst could maintain the high activity on stream for 5 h, with no significant catalyst deactivation.
The effect of obesity on the outcome of total knee replacement (TKR)
Authors: AlOmran Abdullah 
Published: November 2022

Background: The objective of this study was to look for the outcome of TKR in obese individuals. Methods: The data of all patients who had undergone primary TKR between 2005 and 2015 were collected from the QuadruMed Patient Care System and crosschecked with the operating room. The biometric data of age, gender, weight and postoperative follow up, any complications were collected from the medical charts. Patients were classified as per the BMI (Body Mass Index). BMI is classified as per the WHO classification of 2000. Results: Two hundred and four patients fulfilled the criteria for inclusion. The demographic data is given in Table 2. The average age 59.8±9.3 years. Right side was operated in 103 and left in 101 patients. The average BMI was 35.88±7.47 (Range 21.95-54.78); mean duration of surgery was 163.37±29.9 (Range 88-250) minutes. The range of follow up was 5-14 years with the average of 7.49±2.56 years. There were 18 (8.8%) complications. One hundred and three (50.5%) of the patients belonged to Class II Obesity (BMI ≥36Kg/M2). Between class II obesity and Class III obesity (BMI ≥41Kg/M2, the later had 94.4% of the complications. The level of satisfaction was similar in all the groups at 80%. High BMI and longer duration of surgery were important and statistically significant risk factors (p <0.0001 and <0.009) for complications during TKA. Post operative data on VAS, Modified Knee Scoring Score and WOMAC grading, showing low scores of all the assessment in the patients with higher BMI. Conclusions: Our analysis shows that our patients with Class III obesity had over 90% of the complications and we believe that patients in this BMI range should seek ways to reduce their body weight to avoid complications and long-term morbidity.
Spillover Effects and Freemium Strategy in the Mobile App Market
Authors: Deng Yiting , Lambrecht Anja , Liu Yongdong 
Published: November 2022

“Freemium,” whereby a basic service level is provided free of charge but consumers are charged for more advanced features, has become a popular business model for firms selling digital goods. However, it is not clear whether the launch of a free version helps or hurts the demand of an existing paid version. The free version may allow consumers to sample the product before making a purchase decision and subsequently increase demand of the paid version, but it may also cannibalize demand of the paid version. We use a comprehensive data set on game apps from Apple’s App Store that tracks the launch of both the paid and the free versions of individual apps on a daily level to identify whether a freemium strategy stimulates or hurts demand of an existing paid version. We estimate the spillover effects between the free version and the paid version of the same app under a difference-in-difference framework, relying on the fact that app developers cannot predict the exact launch date of the free version of the app due to Apple’s review and approval of apps prior to release and accounting for app-level product heterogeneity. We find that the launch of a free version increases demand of the paid version of the same app. Under the main specification, if the daily number of ratings before the free version’s launch is at the mean, then all else equal, the launch of the free version leads to an 8.9% increase in the daily number of ratings. We then describe multiple robustness checks. Finally, we present evidence that the results are driven by consumers sampling the free version as well as enhanced app discovery and explore the relative importance of the two mechanisms.

Background
The COVID-19 pandemic had a severe impact on women’s birth experiences. To date, there are no studies that use both quantitative and qualitative data to compare women’s birth experiences before and during the pandemic, across more than one country.

Aim
To examine women’s birth experiences during the COVID-19 pandemic and to compare the experiences of women who gave birth in the United Kingdom (UK) or the Netherlands (NL) either before or during the pandemic.

Method
This study is based on analyses of quantitative and qualitative data from the online Babies Born Better survey. Responses recorded by women giving birth in the UK and the NL between June and December 2020 have been used, encompassing women who gave birth between 2017 and 2020. Quantitative data were analysed descriptively, and chi-squared tests were performed to compare women who gave birth pre- versus during pandemic and separately by country. Qualitative data was analysed by inductive thematic analysis.

Findings
Respondents in both the UK and the NL who gave birth during the pandemic were as likely, or, if they had a self-reported above average standard of life, more likely to rate their labour and birth experience positively when compared to women who gave birth pre-pandemic. This was despite the fact that those labouring in the pandemic reported a lack of support and limits placed on freedom of choice. Two potential explanatory themes were identified in the qualitative data: respondents had lower expectations of care during the pandemic, and they appreciated the efforts of staff to give individualised care, despite the rules.

Conclusion
Our study implies that many women labouring during the COVID-19 pandemic experienced restrictions, but their experience was mitigated by staff actions. However, personalised care should not be maintained by the good will of care providers, but should be a priority in maternity care policy to benefit all service users equitably.
Influence of chitosan and chitosan oligosaccharide on dual antibiotic-loaded bone cement: In vitro evaluations
Authors: Tantavisut Saran , Leanpolchareanchai Jiraporn , Wongrakpanich Amaraporn 
Published: November 2022

Background and purposeThe purpose of this study was to investigate the effect of incorporating chitosan (Ch) and chitosan oligosaccharides (ChO) into the commercially premixed antibiotic-loaded bone cement (ALBC). We compare antibiotic release profiles, antibacterial activity, and mechanical properties among different ALBC formulations. The hypothesis was that increasing the amount of Ch and ChO in the cement mixture would increase the antibiotics released and bacterial control. ALBC mixed with Ch or ChO may create a greater effect due to its superior dissolving property.Materials and methodsThe bone cement samples used in this project were made from Copal®G+V composed of vancomycin and gentamicin. To prepare the Ch and the ChO mixed bone cement samples, different amounts of Ch and ChO were added to the polymethylmethacrylate matrix with three concentrations (1%, 5%, and 10%). Drug elution assay, antimicrobial assay,in vitrocytotoxicity, and mechanical properties were conducted.ResultsBone cement samples made from Copal®G+V alone or combined with Ch or ChO can release vancomycin and gentamicin into the phosphate-buffered saline. Mixing ChO into the bone cements can increase the amount of drug released more than Ch. ChO 10% gave the highest amount of antibiotics released. All samples showed good antibacterial properties with good biocompatibilityin vitro. The microhardness values of the Ch and ChO groups increased significantly compared to the control group. In all groups tested, the microhardness of bone cements was reduced after the drug eluted out. However, this reduction of the Ch and ChO groups was in line with the control.InterpretationVarious attempts have been made to improve the ALBC efficacy. In our study, the best bone cement formulation was bone cement mixed with ChO (10%), which had the highest drug release profiles, was biocompatible, and contained antibacterial properties with acceptable mechanical properties. This phenomenon could result from the superior water solubility of the ChO. When ChO leaves the bone cement specimens, it generates pores that could act as a path that exposes the bone cement matrix to the surrounding medium, increasing antibiotic elution. From all above, ChO is a promising substance that could be added to ALBC in order to increase the drug elution rate. However, morein vitroandin vivoexperiments are needed before being used in the clinic.

IntroductionThis paper examines the convergence of the opinions of European higher education institution (HEI) experts on possible implementation of dual career policies and provision areas at university level.MethodsAn online 32-item questionnaire encompassing 26 dual career aspects collected the opinion of European HEI experts as the last phase of a Delphi method preceded by i) focus groups with student-athletes who aimed to identify needs for dual careers and ii) a workshop with 21 dual career experts to generate the statements to be included in the survey. Seventy-one HEI experts from 12 EU member states participated in the survey, rating each dual career aspect identified in previous phases.ResultsThe relative position of each aspect has been plotted based on relevance (x-axis) and feasibility (y-axis). The Quadrant IV of the resulting scatterplots identified the following nine aspects rated as highly relevant and highly feasible for implementation: tutorship/mentorship, psychological support, programmes based on integration of academic departments and sports services, and adaptable programmes to the needs of each student-athletes (assistance/tutorship area), individual study plans and distance learning (curricula requirements area), publicity for student-athletes and initiatives for increasing the awareness of student-athletes and knowledge of dual career issues (social support area), and access to educational facilities (logistic support area).Discussion and conclusionsThe HEI experts’ views represent a coherent and useful starting point to develop a deep understanding of the considered 26 aspects founded on a phenomenological lifeworld-led approach and emphasizes the need for a minimum standard for dual career policies and provisions.
Decrease in medial meniscal extrusion after physical therapy to improve knee pain and range of motion in patients with knee osteoarthritis: A retrospective study
Authors: Yoshizuka Hisayoshi , Taniguchi Takanori , Fukuta Kensuke , Mitsutake Tsubasa , Honda Shigenobu 
Published: November 2022

Background
Medial meniscal extrusion (MME) is the medial displacement of the meniscus, which extends beyond the tibial margin. Studies have shown an association between MME and knee pain and that surgical treatment can reduce the extent of MME. Here, we describe the beneficial effects of physical therapy as a feasible conservative treatment for MME.

Methods
Data of 30 patients with knee osteoarthritis who underwent stretching of the semimembranosus tendon and passive range of motion (ROM) exercises twice a week for 8 weeks were retrospectively analyzed. MME was the measured distance between the medial meniscus and the line connecting the medial borders of the femur and tibia using ultrasound. Ultrasound findings of surrounding tissues, including the deep posterior bundle of the medial collateral ligament (dMCL), were recorded. Additionally, knee extension ROM was measured, and inner knee pain when walking was evaluated using a numerical rating scale.

Results
There were significant improvements between the baseline and 8 weeks for MME in the non-weight-bearing position (3.6 ± 0.3 mm vs. 3.0 ± 0.4 mm), MME in the weight-bearing position (4.3 ± 0.4 mm vs. 3.8 ± 0.5 mm), ROM (−12.3° ± 4.1° vs. −3.1° ± 3.8°), and knee pain (7.0 ± 0.9 vs. 1.1 ± 1.4) (each p < 0.001). In almost all cases in which the knee extension ROM improved, the dMCL was bulging at the baseline; after 8 weeks, the dMCL was flattened, suggesting ligament tension on ultrasound imaging.

Conclusion
Stretching of the semimembranosus tendon and passive ROM exercises may reduce the extent of MME in patients with knee osteoarthritis. The ultrasound findings suggest that improvement in knee extension ROM may have led to the re-acquisition of MCL tension, which may have influenced MME reduction. Therefore, physical therapy may be a feasible conservative treatment for the reduction of MME.
