Published: July 2021

Abstract
At present, in order to prevent the water flow of rivers, streams, spillways, fish ponds and field ditches from soaking and eroding the line foundation, it is often necessary to build revetment to the poles near these waters. In order to completely eliminate the disadvantages of traditional revetment, we need to design the revetment suitable for power concrete pole.

Authors: Zhang Ziqian , Yang Huilin , Zhao Fei , Jiang Nianshun 
Published: July 2021

Abstract
Circular cylindrical thin shells as one of the most energy absorbing elements are used in various engineering applications. One of the most important applications is compressing shells laterally between two rigid plates. Many researchers have work on this issue, but it is hard to be analyzed by the theoretical methods. In the present paper, a finite element model was developed to resemble the compressive process of circular cylindrical shell by two rigid plates laterally. Then a dynamic simulation was carried out using ANSYS LS-DYNA program. The cross-sectional profile and Mises stress distributions as well as the load–displacement curve was obtained by the FEA process, which can reveal the main deformation characteristics of circular cylindrical shells compressed between two rigid plates.

Abstract
The stresses of head cover bolts in a pump turbine were analyzed based on Fluid-Structure-Interaction (FSI). A nonlinear finite element model including head cover, bolts and stay ring was set up by means of contact elements, two head cover models with different flanges were set up to evaluate the effect of head cover to bolts. Results showed that both the uneven pressure distribution and the uneven head cover structure along the circumference have great influence on the stresses of the bolts. In this study, for the head cover with double flange, the single bolt has larger axial stresses amplitude along the outside circle, and the average values of the axial stresses for the 96 bolts are larger too, as a result, the bolts have higher average relative stiffness.

Authors: Ershadi Mahmoud , Jefferies Marcus , Davis Peter , Mojtahedi Mohammad 
Published: July 2021

Abstract
Recent advancements in information technology have benefited the construction sector in more effective storage, analysis, and transmission of information. Making proper project decisions is hinged upon the verified and timely information provided by systems. It is especially the case in large construction projects in which many partners collaborate to deliver a project. Building information modeling (BIM) as an intelligent 3D model-based approach provides construction managers with insight on how to integrate elements of project configuration. In this paper, we theorize the potential contribution of BIM to the systematic management of projects at the project and corporate level. The findings guide practitioners on how to take advantage of this approach towards the integrated planning and control of construction projects.
Double single-channel Kondo coupling in graphene with Fe molecules
Authors: Vicent I M , Chirolli L , Guinea F 
Published: July 2021

Abstract
We study the interaction between graphene and a single-molecule-magnet, [Fe
4(L)2(dpm)6]. Focusing on the closest Iron ion in a hollow position with respect to the graphene sheet, we derive a channel selective tunneling Hamiltonian, that couples different d orbitals of the Iron atom to precise independent combinations of sublattice and valley degrees of freedom of the electrons in graphene. When looking at the spin-spin interaction between the molecule and the graphene electrons, close to the Dirac point the channel selectivity results in a channel decoupling of the Kondo interaction, with two almost independent Kondo systems weakly interacting among themselves. The formation of magnetic moments and the development of a full Kondo effect depends on the charge state of the graphene layer.

Abstract

Background
Minimally invasive oesophagectomy (MIO) for oesophageal cancer may reduce surgical complications compared with open oesophagectomy. MIO is, however, technically challenging and may impair optimal oncological resection. The aim of the present study was to assess if MIO for cancer is beneficial.

Methods
A systematic literature search in MEDLINE, Web of Science and CENTRAL was performed and randomized controlled trials (RCTs) comparing MIO with open oesophagectomy were included in a meta-analysis. Survival was analysed using individual patient data. Random-effects model was used for pooled estimates of perioperative effects.

Results
Among 3219 articles, six RCTs were identified including 822 patients. Three-year overall survival (56 (95 per cent c.i. 49 to 62) per cent for MIO versus 52 (95 per cent c.i. 44 to 60) per cent for open; P = 0.54) and disease-free survival (54 (95 per cent c.i. 47 to 61) per cent versus 50 (95 per cent c.i. 42 to 58) per cent; P = 0.38) were comparable. Overall complication rate was lower for MIO (odds ratio 0.33 (95 per cent c.i. 0.20 to 0.53); P &lt; 0.010) mainly due to fewer pulmonary complications (OR 0.44 (95 per cent c.i. 0.27 to 0.72); P &lt; 0.010), including pneumonia (OR 0.41 (95 per cent c.i. 0.22 to 0.77); P &lt; 0.010).

Conclusion
MIO for cancer is associated with a lower risk of postoperative complications compared with open resection. Overall and disease-free survival are comparable for the two techniques.
Aguascalientes: one of the hottest chronic kidney disease (CKD) hotspots in Mexico and a CKD of unknown aetiology mystery to be solved
Authors: Villalvazo Priscila , Carriazo Sol , Martin-Cleary Catalina , Ortiz Alberto 
Published: July 2021

Abstract
In a recent issue of Clinical Kidney Journal (CKJ), Gutierrez-Peña et al. reported a high incidence and prevalence of advanced chronic kidney disease (CKD) in Aguascalientes, Mexico. This contradicts Global Burden of Disease estimates, which should be updated. A key component of this high burden of CKD relates to young people ages 20–40 years in whom the cause of CKD was unknown [CKD of unknown aetiology (CKDu)]. The incidence of kidney replacement therapy in this age group in Aguascalientes is among the highest in the world, second only to Taiwan. However, high-altitude Aguascalientes, with a year-round average temperature of 19°C, does not fit the geography of other CKDu hotspots. Furthermore, kidney biopsies in young people showed a high prevalence of focal segmental glomerulosclerosis. Potential causes of CKDu in Aguascalientes include the genetic background (no evidence, although podocytopathy genes should be explored) and environmental factors. The highest prevalence of CKD was found in Calvillo, known for guava farming. Thus guava itself, known to contain bioactive, potentially nephrotoxic molecules and pesticides, should be explored. Additionally, there are reports of water sources in Aguascalientes contaminated with heavy metals and/or pesticides. These include fluoride (increased levels found in Calvillo drinking water) as well as naturally occurring arsenic, among others. Fluoride may accumulate in bone and cause kidney disease years later, and maternal exposure to excess fluoride may cause kidney disease in offspring. We propose a research agenda to clarify the cause of CKDu in Aguascalientes that should involve international funders. The need for urgent action to identify and stem the cause of the high incidence of CKD extends to other CKD hotspots in Mexico, including Tierra Blanca in Veracruz and Poncitlan in Jalisco.

Abstract

Aims
The impact of mechanical ventilation (MV) at the time of heart transplantation is not well understood. In addition, MV was recently removed as a criterion from the new US heart transplantation allocation system. We sought to assess for the association between MV at transplantation and 1-year mortality.

Methods and results
We utilized the United Network for Organ Sharing database and included all adult, single organ heart transplantations from 1990 to 2019. We utilized multivariable logistic regression adjusting for demographics, comorbidities, and markers of clinical acuity. We identified 60 980 patients who underwent heart transplantation, 2.4% (n = 1431) of which required MV at transplantation. Ventilated patients were more likely to require temporary mechanical support, previous dialysis, and had a shorter median waitlist time (21 vs. 95 days, P &lt; 0.001). At 1 year, the mortality was 33.7% (n = 484) for ventilated patients and 11.7% (n = 6967) for those not ventilated at the time of transplantation (log-rank P &lt; 0.001). After multivariable adjustment, patients requiring MV continued to have a substantially higher 90-day [odds ratio (OR) 3.20, 95% confidence interval (CI): 2.79–3.66, P &lt; 0.001] and 1-year mortality (OR 2.67, 95% CI: 2.36–3.03, P &lt; 0.001). For those that survived to 90 days, the adjusted mortality at 1 year continued to be higher (OR 1.48, 95% CI: 1.16–1.89, P = 0.002).

Conclusion
We found a strong association between the presence of MV at heart transplantation and 90-day and 1-year mortality. Future studies are needed to identify which patients requiring MV have reasonable outcomes, and which are associated with substantially poorer outcomes.

Abstract

Aims
The use of digitalis has been plagued by controversy since its initial use. We aimed to determine the relationship between digoxin use and outcomes in hospitalized patients with acute coronary syndromes (ACSs) complicated by heart failure (HF) accounting for sex difference and prior heart diseases.

Methods and results
Of the 25 187 patients presenting with acute HF (Killip class ≥2) in the International Survey of Acute Coronary Syndromes Archives (NCT04008173) registry, 4722 (18.7%) received digoxin on hospital admission. The main outcome measure was all-cause 30-day mortality. Estimates were evaluated by inverse probability of treatment weighting models. Women who received digoxin had a higher rate of death than women who did not receive it [33.8% vs. 29.2%; relative risk (RR) ratio: 1.24; 95% confidence interval (CI): 1.12–1.37]. Similar odds for mortality with digoxin were observed in men (28.5% vs. 24.9%; RR ratio: 1.20; 95% CI: 1.10–1.32). Comparable results were obtained in patients with no prior coronary heart disease (RR ratio: 1.26; 95% CI: 1.10–1.45 in women and RR ratio: 1.21; 95% CI: 1.06–1.39 in men) and those in sinus rhythm at admission (RR ratio: 1.34; 95% CI: 1.15–1.54 in women and RR ratio: 1.26; 95% CI: 1.10–1.45 in men).

Conclusion
Digoxin therapy is associated with an increased risk of early death among women and men with ACS complicated by HF. This finding highlights the need for re-examination of digoxin use in the clinical setting of ACS.
The Virtuous Cycle of Agreement
Authors: Louis Philippos , Núñez Matías , Xefteris Dimitrios 
Published: July 2021

AbstractCollective choice mechanisms are used by groups to reach decisions in the presence of diverging preferences. But can the employed mechanism affect the degree of post-decision actual agreement (i.e., preference homogeneity) within a group? And if so, which are the features of the choice mechanisms that matter? Since it is difficult to address these questions in natural settings, we employ a theory-driven experiment where, after the group collectively decides on an issue, individual preferences can be properly elicited. We find that decision mechanisms that promote consensual behaviour generate substantially higher levels of post-decision actual agreement compared to outcome-wise identical procedures that incentivise subjects to exaggerate their differences.

Abstract

Aims
This study determined whether the improvements in hypertension management over the last five decades have influenced subjects’ prognosis.

Methods and results
The study considered 5693 eligible subjects seen January 1969 to February 1991 (follow-up until December 2003) or January 1995 to October 2014 (follow-up until July 2016) in an all-grade hypertension reference centre. Missing data or incomplete follow-ups led to exclude 1036 subjects (18%). The outcome was all-cause death. An adjusted modelling of the excess mortality rate assessed subjects’ net survival over five inclusion periods to allow for the increase in life expectancy of the general population during the same periods. The analysis of 4657 records (mean age: 47 years; 43.2% women) showed that the proportion of subjects with grade 3 hypertension decreased significantly from 43.3% (1142) to only 6.3% (22) over the five periods and that the net survival improved in men and women regardless of the hypertension grade; i.e. the gain in net survival at 15 years was estimated at 12.3% (95% confidence interval: 8.1–22.3). The 15-year restricted mean survival was estimated at 13 years over the first period and 14.8 years over the last period, which is nearly a 2-year gain in life expectancy at 15 years.

Conclusion
Since the 70s and the advent of modern management, the excess mortality of hypertensive subjects (vs. the general population) was markedly reduced. Within a context of trivialization of blood pressure measurement and reluctance to long-term treatments, physicians should consider this advantage and use it to promote blood pressure control.

Abstract

Aims
Epicardial ablation has risen to an essential part of the treatment of ventricular tachycardias (VTs). In this study, we report the efficacy, risks, and current trends of epicardial ablation in structural heart disease as reported in a tertiary single centre over a 12-year period.

Methods and results
Two hundred and thirty-six patients referred for VT ablation underwent a successful epicardial access and were included in the analysis (89% non-ischaemic cardiomyopathy, 90% males, mean age 60 years, mean left ventricular ejection fraction 38.4%). After performing epicardial ablation the clinical VTs were eliminated in 87% of the patients and 71% of the cohort achieved freedom from VT during 22-month follow-up. Twelve patients (5%) suffered major procedure-related complications. Until the end of follow-up 47 (20%) patients died, 9 (4%) underwent a left ventricular assist device implantation and 10 (4%) patients received a heart transplantation. Antiarrhythmic drugs at baseline and during follow-up were independent predictors of VT recurrence. Atrial fibrillation, renal dysfunction, worse New York Heart Association class, and antiarrhythmic drugs at follow-up were associated with worse survival in our cohort.

Conclusion
In this large tertiary single-centre experience, percutaneous epicardial access was feasible in the large majority of the cohort with acceptably low complications rates. A combined endo-/epicardial approach resulted in 87% acute and 71% long-term success. Further studies are needed to clarify the role of routine combined endo-/epicardial ablation in these complex cardiomyopathies.
Estimation of forest canopy structure and understory light using spherical panorama images from smartphone photography
Authors: Arietta A Z Andis 
Published: July 2021

Abstract
Accurate estimates of forest canopy structure are central for a wide range of ecological studies. Hemispherical photography (HP) is a popular tool to estimate canopy attributes. However, traditional HP methods require expensive equipment, are sensitive to exposure settings, and produce limited resolution which dramatically affects the accuracy of gap fraction estimates. As an alternative, hemispherical images can be extracted from spherical panoramas produced by many smartphone camera applications. I compared hemispherical photos captured with a digital single lens reflex camera and 180° lens to those extracted from smartphone spherical panoramas (SSP). The SSP HP method leverages built-in features of current generation smartphones to produce sharper images of higher resolution, resulting in more definition of fine canopy structure. Canopy openness and global site factor from SSP HP are highly correlated with traditional methods (R2 &gt; 0.9), while leaf area index estimates are lower, especially in more closed canopies where traditional methods fail to capture fine gaps.

Published: July 2021

Abstract
The Salmonella research community has used strains and bacteriophages over decades, exchanging useful new isolates among laboratories for the study of cell surface antigens, metabolic pathways and restriction-modification (RM) studies. Here we present the sequences of two laboratory Salmonella strains (STK005, an isolate of LB5000; and its descendant ER3625). In the ancestry of LB5000, segments of ∼15 and ∼42 kb were introduced from Salmonella enterica sv Abony 803 into S. enterica sv Typhimurium LT2, forming strain SD14; this strain is thus a hybrid of S. enterica isolates. Strains in the SD14 lineage were used to define flagellar antigens from the 1950s to the 1970s, and to define three RM systems from the 1960s to the 1980s. LB5000 was also used as a host in phage typing systems used by epidemiologists. In the age of cheaper and easier sequencing, this resource will provide access to the sequence that underlies the extensive literature.

AbstractThiabendazole (TBZ) is an FDA-approved benzimidazole widely used for its antifungal and antihelminthic properties. We showed previously that TBZ is also a potent vascular disrupting agent and inhibits angiogenesis at the tissue level by dissociating vascular endothelial cells in newly formed blood vessels. Here, we uncover TBZ’s molecular target and mechanism of action. Using human cell culture, molecular modeling, and humanized yeast, we find that TBZ selectively targets only 1 of 9 human β-tubulin isotypes (TUBB8) to specifically disrupt endothelial cell microtubules. By leveraging epidemiological pesticide resistance data and mining chemical features of commercially used benzimidazoles, we discover that a broader class of benzimidazole compounds, in extensive use for 50 years, also potently disrupt immature blood vessels and inhibit angiogenesis. Thus, besides identifying the molecular mechanism of benzimidazole-mediated vascular disruption, this study presents evidence relevant to the widespread use of these compounds while offering potential new clinical applications.
