Authors: Xin Fubin , Huang Zhiqiang , Huang Hao , Zhang Hao , Liao Wenjing , Xie Jun 
Published: December 2024

Abstract
An oilfield in the South China Sea will be developed by CO2 injection to enhance oil recovery and carbon sequestration. It is challenging to prevent corrosion in the cementing operation of injection wells, and high requirements are put forward for the anti-corrosion performance of cementing slurry. In this paper, aiming at the sealing problem of the cement ring, which is easy to corrode under the condition of stratified gas injection, the rheological properties and thickening properties of cement slurry, as well as the tensile strength, compressive strength, elastic modulus, and porosity permeability of the cement slurry system, are simulated under the condition of an underground field with polymer emulsion and calcium sulfate whiskers as the research objects. Through experimental and theoretical comparison, the results show that the addition of polymer emulsion and calcium sulfate whisker can significantly improve the tensile strength and tensile strength and reduce porosity and permeability, elastic modulus has been controlled below 7.5 GPa, and the performance has been dramatically improved. In addition, according to electron microscope scanning and other experimental methods, it is found that the cement stone cured by cement slurry with polymer emulsion and calcium sulfate whisker is more compact and compact in structure and has higher strength and toughness, which fully meets the requirements of stratified gas injection conditions, providing theoretical basis and data support for the corrosion prevention of cementing cement slurry in oil fields. Promoting the safe and efficient development of oil and gas resources is of great significance.
Finite element assessment of the biomechanical implications of various internal fixation techniques used in lumbar interbody fusion surgeries
Authors: Fei Kaixuan , Nie Wenzhong 
Published: December 2024

Abstract
The use of lumbar interbody fusion along with an internal fixation device is a common procedure for addressing conditions such as herniated lumbar discs and lumbar spondylolisthesis. As there are fewer comparative studies on the posterior lateral approach, this study can provide a reference for a new surgical approach and a more optimized fixation protocol for the patient; hence, the following study is done. Accurate reconstruction of vertebral geometry and simulation of soft tissues enables the simulation of the implant’s positioning and configuration, as well as its impact on the surrounding tissues, throughout the surgical procedure. The fixation stage and intervertebral stresses, the disc stresses in neighboring segments, and the differences in mobility between stages were compared separately in each model. The total lumbar spine activity during forward flexion, backward extension, lateral bending, and twisting was reduced in Groups A, B, C, and D compared to the intact model. In addition, Group A generally had the least range of motion. As a result, patients in Group A had a more stable spine with a lower likelihood of degeneration.
Synchronization of Chen’s chaotic systems based on single sliding mode controller
Authors: Zhao Haibin , Zhao Qunchao , Liu Chong 
Published: December 2024

Abstract
Synchronization of Chen’s chaotic systems with different initial states based on a single sliding mode controller (SMC) is considered in this paper. A single controller is simple and easy to implement in practical applications. A single SMC controller can make the synchronization error signals converge to zero gradually. It can realize synchronization control. The single controller is designed based on SMC theory and the stability analysis is proved using Lyapunov stability theory. Single SMC with saturation constraints is used for synchronization control of Chen’s chaotic systems in this paper. A numerical simulation based on MATLAB software is presented to show the effectiveness of the single SMC controller with saturation constraints.

Authors: Liang Zhengang , Liu Yingmiao , Zhang Lei , Lu Jiashu , Guo Xuncheng 
Published: December 2024

Abstract
To improve the damage assessment efficiency of anti-ship weapons, the target vulnerability model of typical ships is introduced, and the damage level is classified into severe and moderate damage according to the functional characteristics of the ships. The damage probability calculation model of typical ships is constructed, and the damage assessment system of anti-ship missiles on typical ships is built based on the Unity3D engine. The system can achieve the parameter input of the anti-ship missile, the calculation of the damage probability of the anti-ship missile on typical ships, and the visualization of the damaging effect. For an example of an anti-ship missile analysis, the system visualizes the damage effect of the anti-ship missile on a typical ship, sets the combat tribal speed to 1, 450 m/s and CEP to 10 m, and calculates the damage probability of the anti-ship missile on a typical ship at three different aiming points under the conditions of the bullet-eye meeting with the direction angle of the scattering of fragments of 90° and the angle of fall of 20°. The results show that aiming point 2 has the highest probability of destroying the ship. The designed system is functionally complete and can provide support for the damage assessment of typical ships by anti-ship missiles, and the idea of system development can provide a reference for the design of damage assessment software.

Abstract
To provide an economic and safe destruction program, this paper is based on the jet detonation method of poly energy charge structure design. The use of simulation software is to establish the diameter of the 40 mm polymer charge physical model, and the combat structure model is used for the invasion and detonation simulation calculations. The results show that the theoretical calculations and simulations are in good agreement and the structure can penetrate the 40 mm thick 50SiMnVB shell, to observe the shock wave in the shielding cover and shielding explosives between the transmission process, finding that the thickness of the shell affects the impact detonation mechanism.
Bernard of Clairvaux and the Fragmentation of Charity
Authors: Teubner Jonathan D 
Published: December 2024

Abstract
Chapter 6 turns to the application of Benedict’s Rule in the hands of the most representative of the Benedictine tradition: Bernard of Clairvaux. Framed by Bernard’s last major work De consideratione, a work of counsel dedicated to his one-time pupil Pope Eugenius III, this chapter presents Bernard as attempting to pull together an Augustinian portrait of Paul, Benedictine abbatial authority, and the example of Gregory to craft his pastoral theory and advice on balancing the “active” and “contemplative” lives. As in Gregory, Bernard holds that the caritas of one who rules over others should be guided by the desire to be of service to them and to promote their salvation. However, the chapter shows how Bernard delineates this variety of charity as distinct from the higher level of charity, the pure love of God (amor dei). This distinction informs Bernard’s controversial Liber ad milites temple de laude novae militae, where he imagines a Benedictine-informed rite for going to war.
Epilogue
Authors: Teubner Jonathan D 
Published: December 2024

Abstract
In the Epilogue, the reader is returned to the author’s original motivation for exploring the ways in which beliefs about and commitments to a love-ethic have given rise to concrete practices of charity, and the way in which those practices have promoted, prevented, or destroyed an expandable solidarity. The chapter explores the connection between the practices of charity and prayer through critical engagement with Jean Daniélou’s Prayer as a Political Problem. Summarizing the argument of the book as a whole, the chapter proposes to re-center in theological practice questions about how some idea might be translated into action or implemented by a leader, for the implementation of the idea is intrinsic to the idea, not some external, secondary concern.
Does the Osman Test Go to School? Recent Developments Concerning States’ Positive Obligations to Protect Children in School
Authors: Leisure Patrick 
Published: December 2024

ABSTRACT
In light of the recent Biba v Albania case, this article takes a closer look at states' positive obligations to protect children in school. It tracks a distinct divergence in judicial preference for how positive obligations apply in the school context and illustrates how the Strasbourg Court has inconsistently invoked and applied the Osman test in schooling cases. Recommending that the Strasbourg Court clarify in future case-law the Court's positive obligations doctrine on states to protect children in school, the article concludes with a reflection and a recommendation, based on Judge Tulkens' concurrence in Kayak v Turkey, regarding the Strasbourg Court's role in this important area.
The Magico-Juridical Hypothesis
Authors: Alvarez-Nakagawa Alexis 
Published: December 2024

Abstract
Is there such a thing as a ‘magico-juridical’ phenomenon, designating a threshold of indistinction between magic and law—that is, a phenomenon similar to the concept of the ‘magico-religious’? What prevents us from considering these two terms in relation? What do legal theory and religious studies gain by thinking in this way? Does this construction speak to our political and juridical order? Does it say anything about modernity and secularization? This article addresses some of these questions. It overviews part of the scholarship—from the early works of Marcel Mauss and Paul Huvelin to the most recent writings of Giorgio Agamben—and spotlights a critical realization: magic does not belong to a ‘primitive’ stage that law has overcome, but remains an inherent aspect of its current existence.

Abstract

Introduction
Sleep and exercise are pillars of health. However, the temporal dynamics between these two behaviours remain poorly understood. This study examined the independent between- and within-person associations of sleep duration and onset on next-day exercise likelihood and duration in a large, longitudinal sample of adults under free-living conditions.

Methods
Participants (N=19,977; 6,593,237 person-nights) wore a validated wrist-worn biometric device (WHOOP Strap) for one year. Objective sleep metrics were derived from the wrist-worn device and exercises were logged on a smartphone application. We fit generalized additive mixed models to assess the between- and within-person associations between sleep and exercise variables, adjusted for age, gender, weekday, seasonal effects, biometric feedback, and autocorrelated errors.

Results
At the between-person level, longer average sleep duration and later average sleep onset were each independently associated with reduced exercise likelihood and duration (ps&lt;.001). At the within-person level, sleeping 1 to 1.75 fewer hours and going to sleep 2 to 2.5 hours earlier than usual were each independently associated with increased next-day exercise likelihood and duration (ps&lt;.001). However, further sleep loss and earlier sleep onset advance predicted worse next-day exercise outcomes. Sleeping longer and going to sleep later than usual were negatively associated with next-day exercise (ps&lt;.001).

Discussion
Together, our findings indicate that contrary to symbiotic models of sleep and exercise, individuals may sacrifice time in one health behaviour for time in the other. Interventions aimed at promoting exercise adherence should carefully consider the temporal dynamics between the duration and timing of sleep and next-day exercise outcomes.

Abstract
Sleep-wake state discrepancy is a common phenomenon for individuals with insomnia, where an individual self-reports worse sleep parameter values than observed in polysomnography-derived values. However, this presumes there is no systematic bias in polysomnography-derived versus self-report sleep estimates in healthy individuals, which may not be true. This study aimed to test for potential bias in sleep-wake state discrepancy in a group of healthy individuals (N=49, aged 33.9±14.1 years) who underwent in-laboratory polysomnography (PSG) and completed a concurrent self-reported sleep diary. Healthy individuals demonstrated sleep-wake state discrepancy for multiple sleep parameters, reflected as ‘better’ self-reported sleep values than PSG-derived. For total sleep time (TST), there was a significant difference (of 51.3 minutes, p &lt;.001.) between the sleep diary reported TST (495.8±50.1) and the PSG-derived TST (M=444.5±62.6). Similar findings were also found for wake after sleep onset (diary: M=27.1±34.2, PSG: M=94.9±62.9, p &lt;.001), sleep efficiency (diary: M=90.6%±8.7, PSG: M=75.2%±11.9, p &lt;.001), and sleep onset latency (diary: M=27.4±22.2, PSG: M=53.7±38.0, p &lt;.001). These observations in healthy sleepers are in the opposite direction usually observed in individuals with insomnia. These findings help inform the premise that self-reporting worse sleep parameters than PSG-derived is not a typical phenomenon in healthy individuals; it may be unique to individuals with sleep disorders (i.e., insomnia) and therefore warrants appropriate detection and treatment. Continued research in establishing age/gender-appropriate cut-off levels of healthy sleep-wake state discrepancy in the general population is needed to facilitate more effective detection and treatment of clinically meaningful sleep-wake state discrepancy in those with sleep disorders.
O030 Impact of lemborexant on daytime sleepiness/alertness in participants with comorbid insomnia and mild obstructive sleep apnea
Authors: Moline M , Gardiner F , Kumar D , Cheng J , Boulos M 
Published: December 2024

Abstract

Introduction
Comorbid insomnia with obstructive sleep apnea (COMISA) is associated with daytime functioning and cognitive impairments. Some sleep-promoting medications cause residual morning sleepiness, potentially exacerbating daytime impairment. This post-hoc analysis assessed the impact of lemborexant (LEM), a competitive dual orexin-receptor antagonist approved to treat insomnia in adults, on morning sleepiness/alertness in participants with COMISA.

Methods
Data from a subgroup of adults (≥55 years) with comorbid insomnia and mild OSA (apnea-hypopnea-index, 5 to ≤15 events/h) from Study E2006-G000-304 (NCT02783729), a 1-month, randomized study, were analyzed (N=410). Participants received placebo (PBO), LEM 5mg (LEM5), LEM 10mg (LEM10), or zolpidem tartrate 6.25mg (not reported). A daily sleep diary assessed morning sleepiness/alertness rated from 1 (extremely sleepy) to 9 (extremely alert). The percentage of participants shifting from baseline mild/moderate sleepiness (≤3) towards greater alertness (4, 5, or &gt;5) during the first and last 7 mornings of the study was analyzed.

Results
At baseline, 17/75 (22.7%), 36/112 (32.1%), and 28/104 (26.9%) participants with COMISA receiving PBO, LEM5, or LEM10, respectively, reported mild/moderate sleepiness. Of these participants, a greater percentage shifted from mild/moderate sleepiness towards alertness with LEM5 (66.7%, 82.9%) and LEM10 (64.3%, 75.0%) versus PBO (47.1%, 64.7%) across the first and last 7 mornings, respectively.

Discussion
The sample size was too small to detect statistical differences; however, a greater percentage of participants with COMISA experienced improvements in morning sleepiness across the treatment period with LEM versus PBO. These data align with previous findings that LEM does not affect tasks requiring morning alertness.
P097 Factors influencing adherence to non-invasive ventilation and its impact on clinical outcomes in chronic respiratory failure
Authors: Fernando D , Hamilton G , Yiu J , Roberts J 
Published: December 2024

Abstract

Introduction
Non-invasive ventilation (NIV) is an established treatment for chronic respiratory failure and is associated with improved quality of life, reduction in hospitalizations and improved survival. Despite its benefits, non-adherence to NIV is a challenge and long-term adherence rates to NIV (defined as 4 hours per night) are generally reported in the range of 40 – 60%. Our service recently began implementing patients with ventilatory failure on long-term NIV as part of a statewide service. This study aims to assess adherence to NIV in our service and identify factors influencing adherence to NIV and its impact on clinical outcomes.

Methods
Retrospective study of 61 adult patients commenced on NIV for chronic respiratory failure. Adherence is assessed by evaluating NIV use duration (time of use and proportion, equal or over 4 hours per night) and clinic attendance. Factors considered as predictors for adherence include demographics, clinical characteristics, supports and psychological comorbidities. The effectiveness of NIV is measured by comparing markers of clinical improvement and hospital admissions pre and post NIV initiation. Statistical analyses will identify predictors of adherence and NIV impact on outcomes.

Progress to date
Ethics approval has been obtained and analysis of the patient database has begun. Full results are expected by the end of August.

Intended outcome
This study aims to benchmark our NIV adherence rates and emphasize the importance of adherence to NIV in improving clinical outcomes. It hopes to highlight the need for a holistic approach addressing both clinical and psychosocial factors, to optimize clinical effects.
A Cost Analysis of Enucleation and Evisceration Surgeries for Treatment of Blind, Painful Eyes
Authors: Chen Darren A. , Azad Amee D. , Lin Lisa Y. , Yoon Michael K. 
Published: December 2024

Purpose:
The purpose of this study is to assess the surgical costs of enucleations and eviscerations and their relation to current reimbursement rates using time-driven activity–based costing.

Methods:
This is a retrospective study of patients undergoing enucleation and evisceration surgeries with attachment of muscles (Current Procedural Terminology 65105 and 65093) for a diagnosis of blind, painful eye, from January 1, 2019, to December 31, 2023, at a single, tertiary level, teaching hospital. A time-driven activity–based cost analysis for day of surgery was performed. Operative reports, perioperative times, and supply costs were extracted from the electronic medical record, and average reimbursement fees were taken from Center for Medicare and Medicaid Services data.

Results:
In the 5-year study span, 110 patients underwent enucleation and 52 underwent evisceration for a primary indication of blind, painful eye by 10 different surgeons. The average operating room time and surgical time for enucleation was approximately 9 minutes longer compared with evisceration (p < 0.01). Both surgeries on average resulted in a negative margin with enucleations costing on average $624 more than eviscerations. The breakeven total operating room time for enucleation and evisceration surgery was approximately 86.3 and 83.1 minutes, respectively. From the sample, approximately 79% of enucleation and 60% of evisceration surgeries resulted in a net negative margin.

Conclusions:
On average, the cost of enucleation and evisceration surgeries exceeded the reimbursement amount set by the Center for Medicare and Medicaid Services. Compared with enucleation, evisceration was more time and cost-effective by only a modest margin.

Published: December 2024

Purpose:
To compare regression rates, characteristics, and surgical outcomes of thyroid eye disease patients who underwent orbit, strabismus, or eyelid surgery at various times during or after teprotumumab treatment.

Design:
Multicenter, retrospective, observational cohort study.

Participants:
Adult patients (age >18) with a minimum of 4 infusions of teprotumumab treatment for thyroid eye disease who had had eye surgery during or after treatment.

Methods:
Two groups were formed based on surgery timing: group 1 (G1) (<180 days since last infusion) and group 2 (G2) (≥180 days since last infusion).

Main Outcome Measures:
The primary outcome was postoperative regression rates. Secondary outcomes were postoperative regression characteristics, regression treatment, and orbital decompression proptosis reduction.

Results:
This study evaluated 53 patients (81% female) who underwent 78 surgeries. G1 comprised 24 individuals with 34 surgeries, while G2 comprised 29 patients with 44 surgeries. Regression rates did not significantly differ between G1 and G2 (20.8% vs. 14.7%, p = 0.611). Compared with G1 patients, patients in G2 who regressed showed a significant mean increase in Clinical Activity Score (4.2 vs. 6.1, p = 0.027) and a nonsignificant yet measured increase in proptosis when compared with those in G1 (2.9 vs. 4.25, p = 0.298) at the time of regression. Compared with G1 patients, G2 patients who regressed were equally likely to undergo a repeat course of teprotumumab as group 1 (p = 0.14) but underwent a higher number of additional surgical procedures (p = 0.057). Thyroid stimulating immunoglobin levels uptrended more often in patients who regressed.

Conclusion:
Our study suggests that while the rate of regression may not differ significantly, the severity, clinical impact, and need for additional surgery might be more pronounced for patients who have surgery more than 6 months after their last teprotumumab dose.
