Isreal

After all, more important than the truth is the dehumanization of the enemy which, once operated on a large scale, enables the apathy of the dominant society in the face of the suffering of the dominated. Perhaps this is the greatest indication of the operation's success in substituting reason for emotion. After all, dehumanization is the dematerialization of the other, who stops being a being of flesh and blood and becomes something imaginary, the repository of any evil. It is as necessary to the social acceptance of war as the devil is to Christianity.

MACHINE LEARNING PREDICTION OF VOLUME FRACTION OF GAS-HYDRATES IN NATURAL GAS PIPELINES IN OFFSHORE NIGER DELTA

This study employs multiphase simulations with OLGA software to investigate volume fractions of hydrate in an offshore gas system and develops machine-learning models to predict these fractions. Annually, substantial operating expenditures are allocated to hydrate prevention, with significant costs associated with inhibition (Wang et al., 2022). Hydrate formation along natural gas pipelines is recognized as a critical threat to the success of gas field operations. Despite the importance, no machine learning model has been validated for predicting volume fractions of hydrate in the Niger Delta study area, making this development crucial. Key findings indicate significant hydrate jamming risks in Niger Delta offshore flowlines and risers, with a peak volume fraction of 0.54, highlighting the need for proactive management strategies. Hydrate formation begins at 750 m where fluid temperatures fall below formation thresholds, with a sudden increase in volume at 2971 m, peaking at 3022 m before declining. Machine Learning model comparisons show Random Forest's superior accuracy (correlation coefficient of 0.9391, mean absolute error of 0.0271), while Linear Regression provides interpretable insights for future predictions. All models perform well, with Random Forest leading in accuracy. Regression analysis reveals relationships between volume fractions of hydrate and various parameters, guiding management strategies. The Random Forest and Linear Regression models are valuable for estimating hydrate volumes and enhancing management approaches in natural gas pipelines due to their accuracy and interpretability. These findings underscore the importance of proactive hydrate management in offshore gas systems and the potential of Machine Learning models to optimize these strategies.

Lobar lung transplantation in the mouse.

As an important supplementary approach to clinical in orthotopic lung transplantation (LTx), lobar LTx currently lacks a stable animal model and in the orthotopic left LTx model, the right lung of the donor mouse is completely removed and discarded. We introduce a novel mouse lobar LTx model that potentially provides a mouse model for clinical lobar LTx and increase the utilization rate of the experimental donor. Lobar and orthotopic left LTx were performed in syngeneic strain combinations. We performed micro-computed tomography and tested arterial blood gases to assess the graft function 28 days after transplantation. Hematoxylin-eosin and Masson's trichrome staining were used to evaluate pathological changes. We performed ten lobar LTx with an operation success rate of 90%, accompanied by ten orthotopic left LTx from the same donors with an operation success rate of 100%. The graft preparation for lobar LTx was longer than that of the orthotopic left LTx (42.11±3.79 vs. 30.10±3.14 minutes, P<0.001). The recipient procedure for lobar LTx was nearly equivalent to the orthotopic left LTx. The graft function and histopathological changes for lobar LTx were comparable to those of orthotopic left LTx 28 days after transplantation. We describe a lobar LTx model in the mouse, which potentially provides a model for clinical lobar LTx and effectively addresses the issue of resource wastage in the orthotopic left LTx model.

ShaleSeg: Deep-learning dataset and models for practical fracture segmentation of large-scale shale CT images

Shale gas plays a crucial role as an exploration resource for human life, and its contribution to energy production has been steadily increasing. The success of hydraulic fracturing operations is highly dependent on the understanding of shale fracture propagation at large scales. Currently, the segmentation of large-scale shale fractures is primarily carried out through time-consuming manual or semi-automated methods. The identification of shale fractures is similar to image segmentation, in which deep-learning holds the potential to achieve accurate performance close to human experts. However, its application encounters challenges when dealing with large-scale shale images due to factors such as a lack of datasets, severe artifacts, and limited sample sizes. In this study, we compiled the first publicly available large-scale shale CT dataset, which consists of a total of 4313 scanned images, with over 700 images coming from scanning experiments on 300 cm3 cubic shale samples. We also proposed a new data augmentation method for shale CT images to overcome challenges posed by severe artifacts and small-sample sizes. This method involves simulating image artifacts and reducing high edge gradients along the sample edges, which has proven to be effective in facilitating the efficient training of deep-learning models. We've also conducted several ablation studies to determine the best model design, namely ShaleSeg. ShaleSeg was able to accurately identify multi-scale fractures, achieving a precision of 0.84 and an F-score of 0.81, which is close to the manual results. In the case of minor fractures, precision increased by an increase significantly from 0.191 to 0.513, compared to the traditional algorithm. ShaleSeg significantly improves the accuracy and efficiency of fracture segmentation for large-scale shale images. This advancement will be crucial for a thorough comprehension of the fracture mechanism in shale.

Endoscopic ultrasound-guided biliary drainage vs percutaneous transhepatic bile duct drainage in the management of malignant obstructive jaundice.

Malignant obstructive jaundice (MOJ) is a condition characterized by varying degrees of bile duct stenosis and obstruction, accompanied by the progressive development of malignant tumors, leading to high morbidity and mortality rates. Currently, the two most commonly employed methods for its management are percutaneous transhepatic bile duct drainage (PTBD) and endoscopic ultrasound-guided biliary drainage (EUS-BD). While both methods have demonstrated favorable outcomes, additional research needs to be performed to determine their relative efficacy. To compare the therapeutic effectiveness of EUS-BD and PTBD in treating MOJ. This retrospective analysis, conducted between September 2015 and April 2023 at The Third Affiliated Hospital of Soochow University (The First People's Hospital of Changzhou), involved 68 patients with MOJ. The patients were divided into two groups on the basis of surgical procedure received: EUS-BD subgroup (n = 33) and PTBD subgroup (n = 35). Variables such as general data, preoperative and postoperative indices, blood routine, liver function indices, myocardial function indices, operative success rate, clinical effectiveness, and complication rate were analyzed and compared between the subgroups. In the EUS-BD subgroup, hospital stay duration, bile drainage volume, effective catheter time, and clinical effectiveness rate were superior to those in the PTBD subgroup, although the differences were not statistically significant (P > 0.05). The puncture time for the EUS-BD subgroup was shorter than that for the PTBD subgroup (P < 0.05). Postoperative blood routine, liver function index, and myocardial function index in the EUS-BD subgroup were significantly lower than those in the PTBD subgroup (P < 0.05). Additionally, the complication rate in the EUS-BD subgroup was lower than in the PTBD subgroup (P < 0.05). EUS-BD may reduce the number of punctures, improve liver and myocardial functions, alleviate traumatic stress, and decrease complication rates in MOJ treatment.

Capsular Tension Ring and Iris Hook Use in The Management of Cataract with Phacoemulsification Method in Dogs

The purpose of this study is to evaluate the surgical outcome of capsular tension ring and iris hook use during phacoemulsification in dogs with zonular weakness and miotic pupils. This study includes nineteen dogs (29 eyes) that underwent phacoemulsification (15 dogs/25 eyes) and extracapsular cataract extraction surgery (4 dogs/4 eyes) between February 2014 and February 2015. Patients with any ophthalmic problem other than cataracts were not included in the study. Some dogs did not achieve pharmacologic pupil dilation. These dogs required the use of iris hooks or the insertion of capsular tension rings. The capsular tension ring insertion was used in dogs with zonular rupture in more than half of the zonules. Capsular tension rings were inserted in cases of zonular dialysis and iris hooks were placed to widen the pupil. Fifteen dogs (25 eyes) underwent phacoemulsification, while 4 (4 eyes) received extracapsular cataract extraction (ECCE) surgery due to the difficulty of phacoemulsification in hypermature cataracts. Iris hooks were used in four dogs (8 eyes) for drug-resistant miotic pupils. Capsular tension rings were inserted to stabilize the lens capsule during phacoemulsification and to centralize the intraocular lens (IOL) in the bag. Capsular tension rings in cases of zonular dialysis and iris hooks in drug-resistant miotic pupils improved the success of cataract operations with phacoemulsification. Both are safe and useful for zonular weakness and for maintaining mydriasis during surgery.

Dezocine as preemptive analgesia alleviates ultrapulse CO2 fractional laser treatment induced pain in patients with acne scars.

Ultrapluse CO2 fractional laser technology has emerged as an effective treatment for scar management. However, one drawback of this modality is the pain caused during the procedure. This study aims to explore the efficacy and safety of dezocine (DZC) as preemptive analgesia for reduction of pain induced by ultrapulse CO2 fractional laser treatment for acne scars. The study cohort included 78 outpatients with acne scars between February and April 2023. Patients were randomly assigned into three groups with intravenous injection (iv) of DZC prior to laser treatment: (1) control, iv of saline; (2) DZC group 1 (DZC_1), iv of DZC at 0.15 mg/kg; and (3) DZC_2, iv of DZC at 0.20 mg/kg. After 30 min, one session of ultrapulse CO2 fractional laser treatment on acne scars was performed. Hemodynamics, visual analogue scale (VAS), and anxiety visual analog test (AVAT) were monitored prior to, during, and after the procedure. Operative success rates for patients in the control, DZC_1, and DZC_2 groups were 34.6%, 84.6%, and 100%, respectively. DZC administered with either dosage significantly reduced the VAS and AVAT scores of patients in treatment groups as compared with the subjects in the control group during the course of ultrapulse CO2 fractional laser treatment. Patients in DZC_1 and DZC_2 groups did not show any significant difference in hemodynamic parameters, VAS, and AVAT scores. Temporary adverse effects such as nausea and dizziness were observed in some subjects after treatment; the symptoms were quickly dissolved after a rest in supine position. DZC as preemptive analgesia could effectively reduce pain and anxiety induced by ultrapulse CO2 fractional laser treatment in patients. This study provided an option of preemptive anesthesia to minimize the pain and discomforts associated with laser treatments in clinical practices.

Kombucha fungus bio-coating for improving mechanical and antibacterial properties of cellulose composites

Some microorganisms can produce biofilm to create survival conditions. These biofilms are highly resistant to different environmental conditions, and dealing with them is challenging. However, it significantly increases bacterial resistance. Hence, most relevant articles focus on destroying and preventing microorganisms' biofilm creation, and very few articles have been written on the use of microorganism biofilm for manufacturing (especially biocomposite manufacturing). Also, biofilm production by microorganisms on the intended surface (bio-coating process) is challenging. This study planned the conditions so kombucha fungus produces biofilm on a cellulose layer (bio-coating on the surface). As a result of this action, Kombucha biofilm created a biocomposite with good barrier properties and mechanical properties (tensile index: 59 k Nm/kg, burst index: 4.8 kPa.m2/g, air permeability: 189 ml/min, porosity percentage: %10, density: 0.85 gr/cm3, contact angle:72°)The composite has such strong antibacterial properties that a significant inhibition zone was formed in the well diffusion test, and a semi-inhibition zone was also observed. This inhibition zone for the Gram-positive pathogen (S. aureus) was 10.2 mm, close to the tetracycline control sample (11 mm). (the other antibacterial test results for S. aureus: MIC:15 µl, MBC:25 µl,R-number:8,and for E.coli MIC: 15 µl, MBC:25 µl, R-number7: inhibition zone:7.4 mm) These results, along with the results of the permeability and mechanical tests, further demonstrate the operational success of this surface modification. Also, due to its properties, this biocomposite can be suggested for use in wound dressing, pharmaceutical coating, and protecting food with high nutritional value and perishability.

The profession that came in from the cold: Trust and distrust in espionage

Abstract Trust and distrust are important elements of the fiduciary relationship in the professions. Whether to trust or to distrust someone is a decision that has real consequences for success or failure of secret operations in undercover policing, in fraud investigation, or in audit. In this article, we focus on the spying profession as an extreme context in which we attempt to answer the question: how do spies navigate the trust/distrust dynamic in their work? The world of spies has often been out of bounds for those studying the professions and given that field studies in this context are extremely difficult, we analyzed biographies and autobiographies of secret agents. Based on our analysis, we identified different functions of trust and distrust: trust can be used as an instrument of manipulation and an option of last resort, while distrust is a protective mechanism aimed at shielding from vulnerability. We argue that a better understanding of trust and distrust dynamic may illuminate some of the behaviours of people in other professions.

Navigating HRM practices in the Indian institutional context: multinational vs domestic enterprises in comparative perspective

PurposeThe role of distinct institutional context in shaping employment practices is particularly evident in emerging markets where institutional measures are often evolving and not yet fully established. This presents several challenges, particularly for multinational corporations (MNCs) operating in such contexts. This research paper aims to provide a comparative analysis of HRM practices, specifically recruitment and selection, internal career opportunities and performance appraisals between domestic and multinational companies in a large emerging economy, that is India.Design/methodology/approachIn this study, survey-based data was gathered from a diverse sample of 252 companies, comprising both domestic enterprises (DEs) and MNCs, to collect comprehensive data on HRM practices. The aim is to provide a nuanced understanding of the variations in HRM approaches between DEs and MNCs, taking into account the unique institutional context of the Indian market.FindingsContrary to initial expectations, the study’s findings do not support the hypothesis that MNCs would prioritize more rigorous and effective HRM practices compared to DEs in the Indian context. Instead, the results reveal that DEs place a greater emphasis on effective HRM practices than their MNC counterparts, despite the latter’s international reach and operational success. These findings shed light on the distinctive HRM strategies used by MNCs and DEs when navigating the complexities of the Indian market.Originality/valueThis study contributes to the existing IB literature by providing a comparative perspective that emphasizes DEs proclivity for institutional entrepreneurship and change. Exploring the resource dynamics for both MNCs and DEs, the study showcases them as divergent adaptive navigators within (in)formal institutional logics, adept at navigating and influencing institutional structures and shaping distinct HRM practices. The findings challenge traditional assumptions about HRM priorities of MNCs and DEs.

An evaluation tool for assessing coral restoration efforts

The ever-increasing need for coral restoration as a tool available to mitigate reef declines and aid in the recovery of lost ecosystem services requires improving restoration performance over time through an adaptive management framework to evaluate the status of restoration programs using uniform, consistent metrics. An evaluation tool, presented herein, allows restoration practitioners and managers to self-evaluate the robustness of each project and identify successful metrics, those metrics that need special attention, and changes to restoration strategies that can improve performance and aid recovery. This tool is designed to allow programs to track the progress of each key metric over time to assist in improving upon successes and learning from failures. The metrics within this restoration evaluation tool focus on published best-management practices and have resulted from extensive research conducted by restoration experts over the past 20 years. Common metrics of growth and survival are included, in addition to parameters vital to the operational success of restoration programs, such as coral reproduction, recruitment of associated reef taxa, increasing habitat for reef fisheries, and improving overall reef habitat. Five Caribbean restoration programs, each with at least 15 years of restoration experience, are presented as case studies. Each program was evaluated based on six restoration categories including: field-based nurseries, outplantings, programmatic management, education and outreach, event-driven restoration, and socioeconomic restoration. Category-specific metrics were scored with a binary scoring system and summarized using a stop-light indicator framework, where the resulting color/score indicates the operations tatus of the different program components (Scores &amp;gt;75% = green/successful; 50–74.9% = light green &amp;gt; yellow &amp;gt; orange/intermediate; &amp;lt;49.9% = red/sub-optimal). Composite scores may be used to evaluate individual projects, overall restoration programs, or even large-scale state of regional restoration plans. Overall, four of the five programs scored &amp;gt;75% indicating most of these programs are performing well, are versatile, well managed, and sustainable. Outside of environmental factors and large-scale disturbance events, many programs described resource limitations, including funding and staffing, as reasons for scoring low on some metrics. A holistic evaluation rubric incorporated into programmatic self-assessment can ensure that restoration projects and programs are working towards success and sustainability.

A Max–Min Fairness-Inspired Approach to Enhance the Performance of Multimodal Transportation Networks

Disruptions in multimodal transportation networks can lead to significant damage and loss, affecting not only the networks’ efficiency but also their sustainability. Given the size, dynamics, and complex nature of these networks, it is essential to understand and enhance their resilience against disruptions. This not only ensures their functionality and performance but also supports sustainable development by maintaining equitable service across various communities and economic sectors. Therefore, developing efficient techniques to increase the robustness and resilience of transportation networks is crucial for both operational success and sustainability. This research introduces a multicriteria mixed integer linear programming (MCMILP) model aimed at enhancing the resilience and performance of multimodal–multi-commodity transportation networks. By ensuring effective distribution of commodities, alongside a cost-efficient distribution strategy in the wake of disruptive events, our model contributes significantly to sustainable transportation practices. The proposed MCMILP model demonstrates that integrating equality considerations while seeking a cost-efficient distribution strategy significantly mitigates the impact of disruptions, thereby bolstering the resilience of multimodal transportation networks. To illustrate the capabilities of the proposed modeling approach, we present a case study based on the multimodal transportation network in Colombia. The results show a significant improvement in the number of nodes that satisfy their demand requirements with respect to other approaches based on reducing total unsatisfied demand and transportation costs.

Does the use of acellular dermal matrices (ADM) in women undergoing pre-pectoral implant-based breast reconstruction increase operative success versus non-use of ADM in the same setting? A systematic review protocol

BackgroundBreast cancer is the most common malignancy among women in the UK. Following mastectomy, reconstruction is now integral to the surgical management of breast cancer, of which implant-based reconstruction (IBBR) is the most common type. IBBR initially evolved from pre-pectoral to post-pectoral due to complications, but with developments in oncoplastic techniques and new implant technology, interest in pre-pectoral IBBR has increased.Many surgeons use acellular dermal matrices (ADM); however, there is little evidence in literature as to whether this improves surgical outcomes in terms of complications, failure and patient satisfaction. This review aims to assess the available evidence as to whether there is a difference in surgical outcomes for breast reconstructions using ADM versus non-use of ADM.MethodsA database search will be performed using Ovid MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and Clinicaltrials.org. The search timeframe will be 10 years.Studies will be screened using inclusion and exclusion criteria and data extracted into a standardised spreadsheet. Risk of bias will be assessed. Screening, extraction and risk-of-bias assessments will be performed independently by two reviewers and discrepancies discussed and rectified. Data analysis and meta-analysis will be performed using Microsoft Excel and R software. Forest plots will be used for two-arm studies to calculate heterogeneity and p-value for overall effect.DiscussionWith the renaissance of pre-pectoral IBBR, it is important that surgeons have adequate evidence available to assist operative decision-making. Assessing evidence in literature is important to help surgeons determine whether using ADM for IBBR is beneficial compared to non-use of ADM. This has potential impacts for patient complications, satisfaction and cost to healthcare trusts.Systematic review registrationPROSPERO 2023 CRD42023389072.

The Importance of Wetland Science for the Success of the D-Day Landings

The success of the D-Day landings during World War II was significantly influenced by the detailed reconnaissance and scientific analysis of coastal substrate, particularly peatlands, by Allied wetland scientists. This paper examines the critical role of wetland science in ensuring the feasibility of the Normandy invasion. Initial geological intelligence raised concerns about the stability of the beaches due to extensive peat deposits underlying the Normandy coast. To address uncertainties, the Combined Operations Pilotage Parties (COPP) conducted covert beach surveys, collecting substrate samples crucial for operational planning. These missions, undertaken under challenging conditions, identified suitable landing areas by analysing sediment composition and bearing capacities. The success of D-Day was, in part, attributed to the insights provided by wetland scientists, who highlighted the significance of substrate properties in operational success. Their contributions underscored the interdisciplinary nature of wartime planning, integrating scientific expertise with military strategy. This study illuminates the often-overlooked role of wetland science in pivotal historical events, emphasising its influence on strategic decision-making and operational outcomes during one of the 20th century’s defining battles.
