Published: March 2023

AbstractThe uncertainty of wind speed has a great impact on the reliability of wind turbines. However, previous studies usually used average wind speed or rated wind speed as inputs, ignoring the impact of time and space distribution on wind speed. Based on the hourly ground observation data of meteorological stations, four observation stations are taken as the research object of the uncertainty of wind speed spatial distribution. The four observation stations are divided into single day and one week, and seven data analysis indicators and normal distribution models are used day and night to analyze the uncertainty of wind speed time distribution. The results show that both spatial distribution and temporal distribution are important factors that cause the uncertainty of wind speed. Due to different geographical locations of four stations, their wind speed time domain diagrams are different, and the maximum wind speed, fluctuation frequency and fluctuation amplitude of wind speed at each observation station are different; The wind speed distribution of a single day is quite different from that of a week. The data of a single day and a week are analyzed by day and night, which is quite different from the overall data analysis. The necessity of wind speed uncertainty research of wind turbine considering the temporal and spatial distribution is verified, and it is concluded that normal distribution is not suitable for fitting the distribution model of four stations under study, which lays a foundation for determining the wind speed distribution model, analyzing the power characteristics of wind turbine, evaluating the generation capacity of wind turbine, and analyzing the reliability of wind turbine.
Development of a classification system for equine postoperative complications and its application in a cohort of 190 horses undergoing emergency laparotomy
Authors: Gandini Marco , Giusto Gessica 
Published: March 2023

AbstractBackgroundAccurate reporting of postoperative complications is paramount to understanding procedural outcomes, comparing procedures and assuring quality improvement. Standardising definitions of complications in equine surgeries will improve the evidence of their outcomes. To this end, we proposed a classification for postoperative complications and applied it to a cohort of 190 horses undergoing emergency laparotomy.MethodsA classification system for postoperative complications in equine surgery was developed. Medical records of horses that underwent equine emergency laparotomy and recovered from anaesthesia were analysed. Reported complications pre‐discharge were classified as per the new classification system, and the cost and days of hospitalisation were correlated with the equine postoperative complication score (EPOCS).ResultsOf the 190 horses that underwent emergency laparotomy, 14 (7.4%) did not survive to discharge (class 6 complications), and 47 (24.7%) did not develop complications. The remaining horses were classified as follows: 43 (22.6%) had class 1 complications, 30 (15.8%) had class 2, 42 (22%) had class 3, 11 (5.8%) had class 4; and three (1.5%) had class 5. The proposed classification system and EPOCS correlated with the cost and length of hospitalisation.LimitationsThis was a single‐centre study and the definition of scores was arbitrary.ConclusionsReporting and grading all complications will help surgeons better understand the patients’ postoperative course, thereby reducing subjective interpretation.

AbstractBackgroundThis study aimed to identify complications associated with cerebrospinal fluid (CSF) collection in dogs.MethodsThis was a prospective, observational multicentre study using data collected from 102 dogs undergoing CSF collection for the investigation of neurological disease. CSF was collected from the cerebellomedullary cistern (CMC), lumbar subarachnoid space (LSAS) or both sites. Pre‐, intra‐ and postprocedural data were collected. Descriptive statistics were performed to outline complications associated with CSF collection.ResultsCSF sampling was attempted on 108 occasions, and CSF was acquired on 100 occasions (92.6%). Collection from the CMC was more likely to be successful than that from the LSAS. No dogs exhibited neurologic deterioration following CSF collection. There was no significant difference between pre‐ and post‐CSF collection short‐form Glasgow composite measure pain scores in ambulatory dogs (p = 0.13).LimitationsThe scarcity of complications limited the ability to quantify the incidence of some potential complications reported elsewhere.ConclusionsOur results may be used to inform clinicians and owners that CSF sampling is associated with a low frequency of complications when performed by trained personnel.

Authors: Watkins Moira , Elmenhorst Kine , Weston Philippa , Pink Jonathan 
Published: March 2023

AbstractPseudoankylosis of the temporomandibular joint is infrequent in veterinary practice and mostly seen secondary to trauma. This case report describes the surgical treatment of a 1‐year old, male, entire lurcher that presented with progressive lateral deviation of the muzzle to the left and decreased vertical mandibular range of motion of 6‐month duration. There was no history of trauma, no pain on palpation and complete loss of temporomandibular joint movement, even under sedation. Computed tomography investigation showed a left‐sided temporomandibular pseudoankylosis with osseous fusion between the zygomatic arch and mandible. Surgical excision of the ankylosed bone was performed and achieved an initial 5 cm interincisal gap. The surgical site healed, with no complications reported. Re‐examination at 4 weeks revealed good vertical mandibular range of motion with interincisal gap of approximately 5 cm. At 9 months post‐operatively, the dog had maintained good vertical mandibular range of motion and was able to eat normally, pant and hold large toys.
Hyperkalaemia in a greyhound under general anaesthesia
Authors: Pye Elliot , Ward Rob 
Published: March 2023

AbstractCases of intraoperative hyperkalaemia in healthy greyhound dogs under general anaesthesia have previously been reported in veterinary literature. This case report describes the identification and treatment of hyperkalaemia in an otherwise healthy greyhound undergoing general anaesthesia for a fracture repair. The clinical signs were sudden bradycardia and loss of P waves on the electrocardiogram waveform. Treatment consisted of intravenous 10% calcium gluconate, rapid recovery from anaesthesia, intravenous glucose administration and continued serum potassium monitoring postoperatively. Potential aetiologies of the hyperkalaemia are discussed.
Property as Metaphor: Home and Belonging in Goran Vojnović’s Film Piran – Pirano (Slovenia, 2010)
Authors: Rutar Sabine 
Published: March 2023

AbstractIn this chapter, the author analyzes property in the filmPiran–Pirano(Slovenia, 2010), directed by Goran Vojnović. The film is set in the Istrian town of Piran (It. Pirano) in today’s Slovenia. Its property metaphors encapsulate the historical experience of individuals who lived through the war’s aftermath, through displacement and the rifts between those who “vanished,” those who stayed, those who moved in from elsewhere, and those who—eventually—returned. Real estate is at the metaphorical center stage: an apartment in the town’s center which passes from an Italian family to a Slovene-Bosnian one. Looking from there, the author addresses further metaphorical devices of property: a piano, the town of Piran, the languages spoken (Slovene, Bosnian, Italian), and family graves. Through its cinematic approach, the chapter illustrates biographical experiences of voids—and who (potentially) filled them—in Piran and the Istrian peninsula.
The Joy and Burden of Living: Roma Communities in the Western Borderlands of the Postwar Soviet Union
Authors: Bartash Volha 
Published: March 2023

AbstractFocusing on the processes of post-war community reconstruction and healing, this chapter outlines the experiences of Roma who spent the early post-war years in the western borderlands of the Soviet Union. The author demonstrates that Roma in the Baltic States, western Belarus, and western Ukraine faced similar challenges and choices, for example “to keep on the move or settle,” “to stay in the Soviet Union or leave for Poland,” and so on. Likewise, they found themselves affected by the confrontation between the nationalist insurgencies and the Soviet counterinsurgency. Analysis of the post-war lifestyles and mobility patterns of Roma reveals that their decisions were, first of all, informed by family and community considerations, such as looking for lost family members, taking care of orphans, and providing for their families. Drawing on published memoirs and oral histories, the author discusses how the Roma communities devastated by the Nazi persecution sought to heal from their multiple losses and return to a normal community life.

AbstractA body of literature has previously highlighted the impact of health insurance on observed disparities in congenital cardiac operations. With aims of improving access to healthcare for all patients, the Affordable Care Act (ACA) expanded Medicaid coverage to nearly all eligible children in 2010. Therefore, the present population-based study aimed to examine the association of Medicaid coverage with clinical and financial outcomes in the era the ACA. Records for pediatric patients (≤ 18 years) who underwent congenital cardiac operations were abstracted from the 2010–2018 Nationwide Readmissions Database. Operations were stratified using the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) Category. Multivariable regression models were developed to evaluate the association of insurance status on index mortality, 30-day readmissions, care fragmentation, and cumulative costs. Of an estimated 132,745 hospitalizations for congenital cardiac surgery from 2010 to 2018, 74,925 (56.4%) were insured by Medicaid. The proportion of Medicaid patients increased from 57.6 to 60.8% during the study period. On adjusted analysis, patients with Medicaid insurance were at an increased odds of mortality (1.35, 95%CI: 1.13–1.60) and 30-day unplanned readmission (1.12, 95%CI: 1.01–1.25), experienced longer lengths of stay (+ 6.5 days, 95%CI 3.7–9.3), and exhibited higher cumulative hospitalization costs (+ $21,600, 95%CI: $11,500–31,700). The total hospitalization cost-burden for patients with Medicaid and private insurance were $12.6 billion and $8.06 billion, respectively. Medicaid patients exhibited increased mortality, readmissions, care fragmentation, and costs compared to those with private insurance. Our results of outcome variation by insurance status indicate the necessity of policy changes to attempt to approach equality in surgical out comes for this high-risk cohort.

Tonsil volume and outcome of radiofrequency uvulopalatoplasty with or without tonsillectomy in adults with sleep-disordered breathing
Authors: Tschopp Samuel , Azalmad Khalid , Tschopp Kurt 
Published: March 2023

Abstract
Purpose
Predictors for the outcome of uvulopalatopharyngoplasty with and without tonsillectomy (UPPP ± TE) in sleep-disordered breathing have not been fully established. This study investigates tonsil grade, volume, and preoperative examination in predicting radiofrequency UPP ± TE outcomes.

Methods
All patients undergoing radiofrequency UPP with tonsillectomy if tonsils were present between 2015 and 2021 were retrospectively analyzed. Patients underwent a standardized clinical examination, including Brodsky palatine tonsil grade from 0 to 4. Preoperatively and 3 months after surgery, sleep apnea testing was performed using respiratory polygraphy. Questionnaires were administered assessing daytime sleepiness using the Epworth Sleepiness Scale (ESS) and snoring intensity on a visual analog scale. Tonsil volume was measured intraoperatively using water displacement.

Results
The baseline characteristics of 307 patients and the follow-up data of 228 patients were analyzed. Tonsil volume increased by 2.5 ml (95% CI 2.1–2.9 ml; P < 0.001) per tonsil grade. Higher tonsil volumes were measured in men, younger patients, and patients with higher body mass indices. The preoperative apnea–hypopnea index (AHI) and AHI reduction strongly correlated with tonsil volume and grade, whereas postoperative AHI did not. The responder rate increased from 14% to 83% from tonsil grade 0 to 4 (P < 0.01). ESS and snoring were significantly reduced after surgery (P < 0.01), but the reduction was not influenced by tonsil grade or volume. No other preoperative factor other than tonsil size could predict surgical outcomes.

Conclusions
Tonsil grade and intraoperatively measured volume correlate well and predict the reduction of AHI, while they are not predictive of ESS and snoring response after radiofrequency UPP ± TE.
Positive Wild Animal Welfare
Authors: Browning Heather , Veit Walter 
Published: March 2023

AbstractWith increasing attention given to wild animal welfare and ethics, it has become common to depict animals in the wild as existing in a state dominated by suffering. This assumption is now taken on board by many and frames much of the current discussion; but needs a more critical assessment, both theoretically and empirically. In this paper, we challenge the primary lines of evidence employed in support of wild animal suffering, to provide an alternative picture in which wild animals may often have lives that are far more positive than is commonly assumed. Nevertheless, while it is useful to have an alternative model to challenge unexamined assumptions, our real emphasis in this paper is the need for the development of effective methods for applying animal welfare science in the wild, including new means of data collection, the ability to determine the extent and scope of welfare challenges and opportunities, and their effects on welfare. Until such methods are developed, discussions of wild animal welfare cannot go beyond trading of intuitions, which as we show here can just as easily go in either direction.
A Parametric Study of the Effect of Trees on Residential Footing Design on Expansive Soils
Authors: Sun Xi , Li Jie 
Published: March 2023

AbstractThe influence of trees on residential footings constructed on expansive soils has long been a concern of geotechnical engineers since the invasive tree root could exert suction forces on the soil surrounding them and extract a considerable amount of water depending on seasonality, leading to significant shrinkage settlement and the subsequent foundation failure. In this study, a Eucalypt, Corymbia maculata, planted in an expansive clay site in Melbourne, Australia, was closely monitored for 44 months to assess tree-induced soil moisture patterns and ground movement. Monthly tree water use was measured using a sap flow sensor over 12 months. The results show that the tree consumed 53 kL of water annually, with the highest water demand of 5.9 kL in December and the lowest monthly water use of 2.7 kL in June. The soil suction and moisture content profiles reveal that the desiccating effect of tree roots extended to 3 m depth, while the ground movement data shows a significant shrinkage settlement at a distance equal to half the tree height (HT). A parametric study was also carried out to examine the influence of various parameters on footing design for the effect of trees and the consequent construction cost. It was found that homeowners could save a construction cost of about 32% if the footing is built at a distance of 0.6 HT from the tree compared to the cost for a footing constructed at a distance less than or equal to 0.5 HT.
Fast Computation of Terrain-Induced Gravitational and Magnetic Effects on Arbitrary Undulating Surfaces
Authors: Wu Leyuan , Chen Longwei 
Published: March 2023

AbstractBased on a brief review of forward algorithms for the computation of topographic gravitational and magnetic effects, including spatial, spectral and hybrid-domain algorithms working in either Cartesian or spherical coordinate systems, we introduce a new algorithm, namely the CP-FFT algorithm, for fast computation of terrain-induced gravitational and magnetic effects on arbitrary undulating surfaces. The CP-FFT algorithm, working in the hybrid spatial-spectral domain, is based on a combination of CANDECOMP/PARAFAC (CP) tensor decomposition of gravitational integral kernels and 2D Fast Fourier Transform (FFT) evaluation of discrete convolutions. By replacing the binomial expansion in classical FFT-based terrain correction algorithms using CP decomposition, convergence of the outer-zone computation can be achieved with significantly reduced inner-zone radius. Additionally, a Gaussian quadrature mass line model is introduced to accelerate the computation of the inner zone effect. We validate our algorithm by computing the gravitational potential, the gravitational vector, the gravity gradient tensor, and magnetic fields caused by densely-sampled topographic and bathymetric digital elevation models of selected mountainous areas around the globe. Both constant and variable density/magnetization models, with computation surfaces on, above and below the topography are considered. Comparisons between our new method and space-domain rigorous solutions show that with modeling errors well below existing instrumentation error levels, the calculation speed is accelerated thousands of times in all numerical tests. We release a set of open-source code written in MATLAB language to meet the needs of geodesists and geophysicists in related fields to carry out more efficiently topographic modeling in Cartesian coordinates under planar approximation.
Synthetic Undecidability and Incompleteness of First-Order Axiom Systems in Coq
Authors: Kirst Dominik , Hermes Marc 
Published: March 2023

AbstractWe mechanise the undecidability of various first-order axiom systems in Coq, employing the synthetic approach to computability underlying the growing Coq Library of Undecidability Proofs. Concretely, we cover both semantic and deductive entailment in fragments of Peano arithmetic (PA) as well as ZF and related finitary set theories, with their undecidability established by many-one reductions from solvability of Diophantine equations, i.e. Hilbert’s tenth problem (H10), and the Post correspondence problem (PCP), respectively. In the synthetic setting based on the computability of all functions definable in a constructive foundation, such as Coq’s type theory, it suffices to define these reductions as meta-level functions with no need for further encoding in a formalised model of computation. The concrete cases of PA and the considered set theories are supplemented by a general synthetic theory of undecidable axiomatisations, focusing on well-known connections to consistency and incompleteness. Specifically, our reductions rely on the existence of standard models, necessitating additional assumptions in the case of full ZF, and all axiomatic extensions still justified by such standard models are shown incomplete. As a by-product of the undecidability of set theories formulated using only membership and no equality symbol, we obtain the undecidability of first-order logic with a single binary relation.
Dynamic Games with Strategic Complements and Large Number of Players
Authors: Ramirez Stefanny , Bauso Dario 
Published: March 2023

AbstractWe study dynamic games with strategic complements where each player is modeled by a scalar flow dynamical system with a controlled input and an uncontrolled output. The model originates in inventory control problems with shared set-up costs and a large number of players. An activation cost is shared among active players, namely players who control their dynamics at a given time. As a main contribution, we prove that two-threshold strategies, like the (s, S) strategies used in inventory control, are mean-field equilibrium strategies in dynamic games with a large number of players. Furthermore, we provide conditions for the convergence of the nonstationary mean-field equilibrium to the stationary one in the limit.
Surgical versus interventional coronary revascularization in kidney transplant recipients: a systematic review and meta-analysis
Authors: El-Qushayri Amr Ehab , Reda Abdullah 
Published: March 2023

Abstract
Aim
To study the most beneficial coronary revascularization strategy in kidney transplant recipients (KTR).

Methods
In 16th June 2022 and updated on 26th February 2023, we searched in five databases including PubMed for relevant articles. The odds ratio (OR) together with the 95% confidence interval (95%CI) were used to report the results.

Results
Percutaneous coronary intervention (PCI) was significantly associated with significant lower in-hospital mortality (OR 0.62; 95%CI 0.51–0.75) and 1-year mortality (OR 0.81; 95%CI 0.68–0.97), but not overall mortality (mortality at the last follow-up point) (OR 1.05; 95%CI 0.93–1.18) rather than coronary artery bypass graft (CABG). Moreover, PCI was significantly associated with lower acute kidney injury prevalence (OR 0.33; 95%CI 0.13–0.84) compared to CABG. One study indicated that non-fatal graft failure prevalence did not differ between the PCI and the CABG group until 3 years of follow up. Moreover, one study demonstrated a short hospital length of stay in the PCI group rather than the CABG group.

Conclusion
Current evidence indicated the superiority of PCI than CABG as a coronary revascularization procedure in short- but not long-term outcomes in KTR. We recommend further randomized clinical trials for demonstrating the best therapeutic modality for coronary revascularization in KTR.
