Veterinary radiologic error rate as determined by necropsy
Authors: Cohen Jonathan , Fischetti Anthony J. , Daverio Heather 
Published: June 2023

AbstractA large‐scale postmortem auditing of antemortem imaging diagnoses has yet to be accomplished in veterinary medicine. For this retrospective, observational, single‐center, diagnostic accuracy study, necropsy reports for patients of The Schwarzman Animal Medical Center were collected over a 1‐year period. Each necropsy diagnosis was determined to be either correctly diagnosed or discrepant with its corresponding antemortem diagnostic imaging, and discrepancies were categorized. The radiologic error rate was calculated to include only clinically significant missed diagnoses (lesion was not reported but was retrospectively visible on the image) and misinterpretations (lesion was noted but was incorrectly diagnosed). Nonerror discrepancies, such as temporal indeterminacy, microscopic limitations, sensitivity limitations, and study‐type limitations were not included in the error rate. A total of 1099 necropsy diagnoses had corresponding antemortem imaging; 440 diagnoses were classified as major diagnoses, of which 176 were discrepant, for a major discrepancy rate of 40%, similar to reports in people. Seventeen major discrepancies were diagnoses that were missed or misinterpreted by the radiologist, for a calculated radiologic error rate of 4.6%, comparable with error rates of 3%–5% reported in people. From 2020 to 2021, nearly half of all clinically significant abnormalities noted at necropsy went undetected by antemortem imaging, though most discrepancies owed to factors other than radiologic error. Identifying common patterns of misdiagnosis and discrepancy will help radiologists refine their analysis of imaging studies to potentially reduce interpretive error.
Evaluation of the effect of copper on the restart of a novel combined two‐stage anaerobic digester
Authors: Mohan S. Mariraj , Swathi T. 
Published: June 2023

AbstractThe performance of the modified upflow anaerobic sludge blanket (MUASB) reactor–static granular bed reactor (SGBR) series was evaluated during the restart after a starvation period of 6 months. The steady‐state chemical oxygen demand (COD) removal of the reactor series obtained during the restart with copper was 98 ± 1.96% with the corresponding biogas production and copper removal of 0.218‐m3/kg CODdigested and 81.5%, respectively. Even though the biogas production of the reactor series with copper decreased because of the inhibitory effect of the accumulated copper on the methanogens, the reactor series was maintained stable throughout the operation with the effluent characteristics well within the discharge standards. The resumption of feed after starvation was sufficient for the recovery of the biomass from a dormant to an active state when operated with and without copper. The restart of the reactor series with copper was achieved in 35 days, indicating robustness and sustainability even after starvation.
Efficient Control of a Switched Inertance Hydraulic Converter With a Time-Varying Load
Authors: Yuan Chenggang , Plummer Andrew , Pan Min 
Published: June 2023

Abstract
Digital hydraulics is a novel alternative to proportional or servovalve-controlled systems in fluid power engineering, providing hydraulic systems with high-energy efficiency, good controllability, and insensitivity to contamination. Switched inertance hydraulic converters (SIHCs) are new digital hydraulic devices that can adjust flow and pressure by digital switching instead of throttling the flow. In this paper, an efficient closed-loop control system is proposed for SIHCs subject to time-varying loading conditions in which the load pressure and/or flow varies with time. The control system is designed to operate SIHCs at optimized switching frequencies and ratios that maximize system efficiency when the load varies. With the proposed controller, the SIHC can effectively adapt to the time-varying load and has achieved up to 10% efficiency improvement and up to 65% pressure ripple reduction without affecting the system's dynamic responses, compared with using a nonoptimized controller. The work shows the feasibility and advantages of simultaneously controlling the switching ratio and switching frequency of SIHCs with a time-varying load. As time-varying loading conditions are commonly found in hydraulic applications, the research outcomes constitute an important aspect in the design and development of highly efficient SIHCs and their practical use in hydraulic machinery.
Importance of Preferential Segregation by Aerodynamics in Dust Rig Tests
Authors: Miranda Cairen , Palmore John 
Published: June 2023

Abstract
This work studies a particle injection rig to understand how its design affects particle impingement and rebound from a target plate. The motivation behind this study is to understand how dust ingestion affects aviation gas-turbine engines. The particles are injected into a constant area duct upstream of the plate, and they exit through a converging nozzle. The major result concerns how particles respond differently to changes in the flow field based on their diameter. Near the plate, small particles follow the flow streamlines which causes them to both significantly slow down and to disperse in all directions. However, large particles move ballistically, so they impact the plate with nearly the same velocity and orientation they had at the duct exit. Reynolds-averaged Navier–Stokes (RANS) simulations are compared to large eddy simulation (LES). While RANS are capable of predicting mean particle impact statistics, they display narrower statistical variation than LES, suggesting that particle dispersion is underpredicted in RANS.

AbstractUsing the global fitting framework, we constrain the MSSM with an eV-scale gravitino as the lightest supersymmetric particle, and the six electroweakinos (neutralinos and charginos) as the only other light new states. We combine 15 ATLAS and 12 CMS searches at 13 TeV, along with a large collection of ATLAS and CMS measurements of Standard Model signatures. This model, which we refer to as the $${{\tilde{G}}}$$

Early evolution of fully convective stars in scalar–tensor gravity
Authors: Gomes Débora Aguiar , Wojnar Aneta 
Published: June 2023

AbstractIn this work, the early evolution of low-mass fully convective stars is studied in the context of DHOST (degenerate higher order scalar-tensor) theories of gravity. Although it is known that the hydrostatic equilibrium equation is modified for scalar-tensor gravity, the consequent modifications to the early evolution phases of a star were not explored in this framework. With this in mind, we consider three evolutionary phases—contraction to the main sequence, lithium burning and entrance to the main sequence—and investigate how each of these phases is affected by the theory’s parameter. Taking these effects into account, we are able to show, among other things, that the Hayashi tracks are shifted and the star’s age is considerably modified.
A Simple and Efficient Method for Accelerating Construction of the Gap-Greedy Spanner
Authors: Salami Hosein , Nouri-Baygi Mostafa 
Published: June 2023

Let [Formula: see text] be the complete Euclidean graph on a set of points embedded in the plane. Given a constant [Formula: see text], a spanning subgraph [Formula: see text] of [Formula: see text] is said to be a [Formula: see text]-spanner, or simply a spanner, if for any pair of nodes [Formula: see text], [Formula: see text] in [Formula: see text] there exists a [Formula: see text]-path in [Formula: see text], i.e., a path between [Formula: see text] and [Formula: see text] whose length is at most [Formula: see text] times their distance in [Formula: see text]. Gap-greedy spanner, proposed by Arya and Smid, is a light weight and bounded degree spanner in which a pair of points [Formula: see text] is guaranteed to have a [Formula: see text]-path, if there exists at least one edge with some special criteria in the spanner. Existing algorithms for computing the gap-greedy spanner determine the existence of such an edge for each pair of points by examining the edges of the spanner, which takes [Formula: see text] time, however in this paper, we have presented a method by which this task can be done in [Formula: see text] time. Using the proposed method and well-separated pair decomposition, we have proposed a linear-space algorithm that can compute the gap-greedy spanner in [Formula: see text] time. How to use the well-separated pair decomposition to compute this spanner was proposed by Bakhshesh and Farshi, however using an example, we have shown that one of the algorithms they have proposed for this purpose is incorrect. We have performed various experiments to measure the duration and amount of memory used by the algorithms for computing this spanner. The results of these experiments showed that the proposed method, without a significant effect on the amount of memory consumed compared to previous algorithms, leads to a significant acceleration in the construction time of this spanner.

Recently, the thought of nanotechnology has endowed mankind to create materials of nanometer magnitudes. Nanoparticles or nanomaterials have diverse optical, chemical, thermal and physical possessions from their pre-supremacy corresponding item. Hence, this paper comprises the features of a Casson–Williamson flow field with nanoparticles. Here, we explored the impact of rate slip precondition on the mechanics of heat and mass transport over a stretched sheet with viscous dissipation, and heat generation in an exceedingly porous medium. The influence of Soret–Dufour, magneto-hydrodynamics (MHD) and thermal radiation is presumed. All chemical science specifications of nanofluid are measured as constant. As a result of motion of nanofluid particles, the fluid concentration is inspected underneath chemical implications. A collection of coupled partial differential frameworks is accustomed mathematically to formulate the physical model. The scheme for numerical study named Runge–Kutta approach along with shooting technique is implied to solve the obtained equations. The numerical procedure is then displayed pictorially, where fluid velocity, temperature and concentration against various pertinent parameters are examined. The velocity of the nanofluid encompasses a quicker rate within the deficiency of a magnetic factor; however, the velocity field possesses a reverse trend for Casson factor. The higher Eckert number intensifies the temperature of Casson fluid. Furthermore, the Casson parameter and the velocity slip parameter reduce the drag force and local Nusselt number.

Purpose: Most spinal osteotomy procedures applied for spinal deformity and concomitant malalignment cases are associated with varied complications. This study evaluates the short- to midterm clinical and radiographic efficacy of the transpedicular anterior opening osteotomy technique. Methods: We retrospectively enrolled six patients who underwent transpedicular anterior opening osteotomy due to symptomatic rigid kyphotic deformity from May 2005 to 2016. During surgery, we created a new fracture line at the collapsed anterior vertebral body through bilateral pedicles, filled spaces with compacted bone grafts while preserving posterior elements, including lamina, and secured structure using posterior instrumentation. The kyphotic Cobb angle, Visual Analog Scale (VAS), and Oswestry Disability Index (ODI) before and after surgery were measured and analyzed. Results: The mean preoperative kyphotic Cobb angle was [Formula: see text] while the postoperative value was [Formula: see text]. The mean correction angle was [Formula: see text]. The mean follow-up duration was [Formula: see text] months. During the final follow-up, the mean kyphotic angle was not statistically different from the postoperative values. All patients with documented VAS Back and ODI had improved values postoperatively. Conclusions: Transpedicular anterior opening osteotomy with posterior element preservation improves clinical outcomes and is safe and effective in correcting regional, fixed kyphotic deformities.

We establish global-in-time averaging for the [Formula: see text]-critical dispersion-managed nonlinear Schrödinger equation in the fast dispersion management regime. In particular, in the case of nonzero average dispersion, we establish averaging with any subcritical data, while in the case of a strictly positive dispersion map, we obtain averaging for data in [Formula: see text].

Published: June 2023

Let [Formula: see text] be an open connected domain and [Formula: see text] stand for the Laplacian in [Formula: see text]. For a uniformly bounded sequence [Formula: see text] having a fixed sign and non-positive bi-harmonic functions [Formula: see text], we prove that there exists a sequence of solutions [Formula: see text] to [Formula: see text] with a total curvature [Formula: see text] such that [Formula: see text] for [Formula: see text] and [Formula: see text] for [Formula: see text], where [Formula: see text] is the zero set given by [Formula: see text] In particular, when [Formula: see text] is smoothly bounded and [Formula: see text], we obtain that [Formula: see text] blows up on [Formula: see text] for any [Formula: see text]. This extends the work of Hyder et al. who treated the analogue in even dimensions and complements a previous result in dimension three. We also consider a radial case with no blowing up phenomena and large total curvature.

Published: June 2023

Design/methodology/approach: Converting data into information and its diffusion along all organization units has become a vital survival skill. At this point, an ERP system provides an invisible network among a company’s internal and external stakeholders and plays a strategic role. Moreover, ERP systems offer some advantages. For example, integrating financial, customer, and order information, speeding up production processes, and reducing stock level and order lead time. Therefore, we propose an integrated spherical fuzzy-analytical hierarchy process (SF-AHP) and spherical fuzzy-combinative distance-based assessment (SF-CODAS) framework to prioritize the best ERP software provider for the defense industry. Purpose: Despite having the advantages mentioned above, some crucial aspects must be considered while selecting an ERP package. Factors such as high cost, difficulty in installation, and security threats can be very challenging. The latter issue needs special care in the defense industry. This study aims to design an evaluation framework for the ERP selection problem in the sector. Findings: One of the pivoting defense companies in Turkey is chosen as a case study. Seven ERP systems are evaluated with the proposed model. The results show that the proposed model can be successfully implemented in a defense company context. Furthermore, a sensitivity analysis proves the robustness of the approach to varying threshold parameters in CODAS and different fuzzy weighting approaches. Originality/value: The defense professionals prioritize a different set of selection criteria than conventional manufacturing firms. The study provides a rare holistic framework for the defense industry using a hybridized SF-AHP-CODAS technique. Thus, the study may serve as reference work for the researchers and decision-makers during the digitalization journey of defense firms.

Background/Objective (s) Completion pancreatectomy (C.P.) is one acceptable treatment of choice in clinical scenarios such as management of post-pancreatectomy complications and recurrence in the pancreatic remnant. Studies referring to completion pancreatectomy as a distinct operation are limited, without emphasizing at the operation itself, rather reporting completion pancreatectomy as a possible option for treatment of various diseases. The identification of indications of CP in various pathologies and the clinical outcomes are therefore mandatory. Methods A systematic literature search was performed in the Pubmed and Scopus Databases (February 2020),guided by the PRISMA protocol, for all studies reporting CP as a surgical procedure with reference at indications for performing it combined with postoperative morbidity and/or mortality. Results Out of 1647 studies, 32 studies from 10 countries with 2775 patients in total, of whom 561 (20.2%) CPs met the inclusion criteria and were included in the analysis. Inclusion year ranged from 1964 to 2018 and were published from 1992 until 2019. 17 studies with a total number of 249 CPs were performed for post-pancreatectomy complications. Mortality rate was 44.5% (111 out of 249). Morbidity rate was (72.6%). 12 studies with 225 CPs were performed for isolated local recurrence after initial resection with a morbidity rate of 21.5% and 0% mortality rate in the early postoperative period. Two studies with a total number of 12 patients reported CP as a treatment option for recurrent neuroendocrine neoplasms. The mortality in those studies was 8% (1/12) and the mean morbidity rate was 58.3% (7/12). Finally, CP for refractory chronic pancreatitis was presented in one study with morbidity and mortality rates of 19% and 0%, respectively. Conclusion Completion pancreatectomy is a distinct treatment option for various pathologies. Morbidity and mortality rates depend on the indications of performing CP, the status performance of the patients and whether the operation is performed electively or urgently.
Cholecystoenteric Stent-Related Complications: Rendering the Inoperable Patient Operable
Authors: Chang Jenny H. , Naples Robert , Simon Robert 
Published: June 2023

Introduction Cholecystoenteric stenting is an alternative treatment for cholecystitis. However, complications with this approach can render a need for surgical intervention. Methods A case series of three patients undergoing surgery for a cholecystoenteric stent-related complication. Results Patient 1 was a 42-year-old male with history of lung transplant who had a cholecystoenteric stent placed for acalculous cholecystitis. One year later the stent became occluded with return of symptoms. Endoscopic replacement failed. A laparoscopic cholecystectomy with modified Graham patch was performed. Patient 2 is a 73-year-old female with acalculous cholecystitis in the setting of metastatic colon cancer on FOLFOX. Antibiotic treatment failed. A cholecystoenteric stent was attempted, but the stent dislodged during deployment. The fistula tract was clipped, and a percutaneous cholecystostomy drain was placed, which noted a leak at the gallbladder infundibulum. The patient deteriorated clinically and was taken emergently for an open cholecystectomy. Patient 3 was a 71-year-old male with history of ischemic cardiomyopathy who had a cholecystogastric stent placed for necrotizing gallstone pancreatitis. The stent migrated into the gastrointestinal tract and he developed post-prandial pain. A cholecystectomy and modified Graham patch repair of the gastrotomy was performed. This failed as the gastrotomy was too close to the pylorus. He underwent re-operation with Heineke–Mikulicz pyloroplasty. All patients recovered without any cardiopulmonary complications. Conclusion With the increasing utility of cholecystoenteric stents, surgeons should be aware of the complications and have a plan for managing the duodenotomy or gastrotomy. Shared-medical decision-making involving surgeons should be applied when placing these stents.

Background: Adopting healthy weight-related behaviours in emerging adulthood has long-term health benefits. Digital interventions using game-elements have the potential to improve diet and physical activity outcomes. Universities are influential settings in shifting emerging adults’ behaviour and can deliver health-promoting interventions to young adults. Objectives: To investigate the effect of an online intervention using quiz-games on nutrition knowledge, diet quality, physical activity and sitting time in a sample of university students. Design: Randomised, single-blind, controlled trial. Setting: Two UK Universities including a total of 88 students from different faculties. Method: The intervention group ( n = 50) had access to 10 quiz-games and a website for 10 weeks. The control group ( n = 38) received no such resources. Main outcomes were nutrition knowledge, diet quality, physical activity and sitting time assessed by self-administered questionnaires. Frequency and performance of the quiz-games played, and the effect of time (days) on performance after playing a quiz-game for the second time, were also investigated. Results: No significant differences were found between groups over time in any of the outcomes. The outcomes remained non-significant when engagement rates with the quiz-games were considered. Among the 35 game-players ( n = 15 did not play any game), 15 played at least one quiz-game. Frequency of playing a quiz-game by all students ranged from 43 to 17 times, and mean scores (% of correct answers) ranged from 55% to 82%. When repeating a quiz-game within 8 days, the performance (score) was improved while after that point, performance remained the same or decreased. Conclusion: Online game-based interventions can be easily implemented in university settings. However, further research is needed on their design to enhance engagement and identify key factors affecting students’ behaviour to increase their effectiveness.
