Published: July 2023

Abstract
Background Despite its many advantages, prepectoral breast reconstruction also carries the risk of implant rippling. The recent introduction of partial superior implant coverage using a pectoralis muscle slip in prepectoral direct-to-implant (DTI) breast reconstruction has shown the potential to minimize upper pole rippling. The purpose of this study was to identify factors associated with rippling and the effectiveness of our surgical technique.
Methods In total, 156 patients (186 breasts) who underwent prepectoral DTI breast reconstruction between August 2019 and March 2021 were identified retrospectively. Patient data were analyzed from medical records. Univariable and multivariable logistic analyses were performed to contextualize the risks associated with rippling deformity relative to demographic characteristics and other clinical factors. Retrospective propensity-matched analysis was performed to identify the relationship between rippling deformity and the reconstruction method.
Results Patients with body mass index (BMI; odds ratio [OR], 0.736; p < 0.001), those with a postoperative chemotherapy history (OR, 0.324; p = 0.027) and those who received breast reconstruction via the superior coverage technique (OR, 0.2; p = 0.004), were less likely to develop rippling deformity. The median follow-up period was 64.9 weeks, and there were no significant differences between patients in types of mastectomy, implant, or acellular dermal matrix. Patients who underwent superior coverage technique-based reconstruction showed significantly reduced rippling (OR, 0.083; p = 0.017)
Conclusion Patients with higher BMI and prior postoperative chemotherapy were less likely to develop rippling deformity. The superior coverage technique can be effective in minimizing upper pole rippling.
Small Aromatics Bearing Two Diarylamino Termini: Highly Reducing Organic Photocatalysts
Authors: Koike Takashi 
Published: July 2023

AbstractSmall aromatics such as anthracene, naphthalene, or benzene bearing two diarylamino termini function as highly reducing organic photocatalysts (OPCs). In particular, the small aromatic core remarkably enhances the reducing power of the catalyst in the excited state. An appropriate combination of an OPC and an electron-accepting fluoroalkylating reagent is the key to successful radical fluoroalkylation. The basic design of the photocatalyst and the photocatalytic fluoroalkylation of olefins are discussed.1	Introduction2	Basic Catalyst Design and Photo- and Electrochemical Properties3	Photocatalytic Reactions of 9,10-Bis(diphenylamino)anthracene Derivatives4	Photocatalytic Reactions of 1,4-Bis(diphenylamino)naphthalene Derivatives5	Photocatalytic Reactions of 1,4-Bis(diphenylamino)benzene6	Summary and Outlook
Laryngeal Mask Airway Clinical Use and Training: A Survey of North American Neonatal Health Care Professionals
Authors: Robin Beverley , Soghier Lamia M. , Vachharajani Akshaya , Moussa Ahmed 
Published: July 2023

Objective The aim of this study was to explore North American neonatal health care professionals' (HCPs) experience, confidence, skill, and training with the laryngeal mask airway (LMA).
Study Design This was a cross-sectional survey.
Results The survey was completed by 2,159 HCPs from Canada and the United States. Seventy nine percent had no clinical experience with the LMA, and less than 20% considered the LMA an alternative to endotracheal intubation (EI). The majority had received LMA training; however, 28% of registered nurses, 18% of respiratory therapists, 17% of physicians, and 12% of midwives had never inserted an LMA in a mannequin. Less than a quarter of respondents agreed that the current biennial Neonatal Resuscitation Program instruction paradigm is sufficient for LMA training. All groups reported low confidence and skill with LMA insertion, and compared with all other groups, the respiratory therapists had the highest reported confidence and skill.
Conclusion This survey study, which is the first of its kind to include midwives, demonstrates that neonatal HCPs lack experience, confidence, skill, and training with the LMA, rarely use the device, and in general, do not consider the LMA as an alternative to EI. These findings contribute to, and support the findings of previous smaller studies, and in conjunction with the diminishing opportunities for EI, highlight the need for programs to emphasize the importance of the LMA for neonatal airway management and prioritize regular LMA training, with focus that parallels the importance placed on the skills of EI and mask ventilation.

AbstractIn light of the market uncertainty for hospitality and tourism companies caused by COVID-19, which even led to the legal closure of borders, a study model is proposed. Our model considers market uncertainty as a moderator of the principles of business management. This moderator leads to a sustainable competitive advantage through organizational values, participative leadership, market orientation and innovative intensity. The viability of the proposed model has been analyzed with a mixed methodology using the Smart-PLS tool, on the one hand, and two fsQCA-based samples of hospitality and tourism companies located in Spain and South Korea, on the other hand. The results show the relevance of participative leadership supported by organizational values in obtaining a sustainable competitive advantage. This will help the tourism sector to adapt to future health pandemics. Market uncertainty has not affected participative leadership in achieving this sustainable competitive advantage.
Health system recovery in Northwest Syria–challenges and operationalization

Published: July 2023

AbstractThe demonstrations in Syria in 2011 became an uncompromising conflict that divided the country into three main areas of control: governmental areas, northeast Syria, and Northwest Syria. A series of United Nations resolutions adopted in 2014 authorizing official cross-border humanitarian aid in opposition-held areas to allow humanitarian agencies and organizations to use routes across the border from neighborhood countries like Turkey to deliver humanitarian assistance to people in need in Syria. The resolution was extended annually until 2021 when it was adapted to involve a cross-line humanitarian response from governmental areas besides cross-border operations. The last adaptation of the cross-border resolution, whose original form was interpreted as a politicized action by Russia and China, implicates an unframed and unplanned transition from an emergency to an Early Recovery status. Without an appropriate framework for the current geopolitical complexity in Syria, Early Recovery programs are doomed to fail, resulting in further complications in the political and humanitarian scenes. Moreover, the effectiveness of the cross-line mechanism is questionable, considering the lack of accessibility and acceptability for Damascus-based humanitarian operations in areas out of government control. The article reviews studies about Early Recovery guidelines and operational frameworks of health systems recovery in post-conflict settings to derive a practical and hybrid framework for operationalizing health system recovery in Northwest Syria, considering current geopolitical and humanitarian circumstances. This article draws upon the six building blocks of the health system, the essential package of public health services, Early Recovery integration criteria, health system resilience dimensions in the literature, and public health determinants to identify context-specific health system recovery challenges and priorities. As a result, we introduce a new health system recovery framework, which is operationalized for the context of Northwest Syria.

AbstractThe design and quality of the neighbourhood built environment can encourage health-supportive behaviours and support cardiometabolic health. However, despite the relationships between demographic and behavioural risk factors of metabolic syndrome being investigated by many studies, only some studies have directly estimated the associations between the built environment and metabolic syndrome. Using data from Canada, we examined the associations between the neighbourhood built environment and metabolic syndrome. Data from Alberta’s Tomorrow Project participants, conducted in Alberta, Canada, was used (n = 6718). Metabolic syndrome was defined as the presence of at least three clinical risk factors among lipid levels, blood pressure, and waist circumference. The normalised difference vegetation index was used to quantify the greenness of each participant’s neighbourhood. Built attributes of participants’ neighbourhoods associated with supporting physical activity, including dwelling density, intersection density, and the number of points of interest, were obtained via the Canadian Urban Environmental Health Research Consortium. Increases in the number of points of interest and total active living environment-friendliness of the neighbourhood were associated with having fewer metabolic syndrome risk factors (b = −0.11, 95% CI −0.16, −0.07 and b = −0.03, 95% CI −0.05, −0.01, respectively) and lower odds of metabolic syndrome (OR = 0.89, 95% CI 0.84, 0.094 and OR = 0.97, 95% CI 0.95, 0.99, respectively). Furthermore, higher dwelling density was associated with having fewer metabolic syndrome risk factors (b = −0.05, 95% CI −0.09, −0.01). Our findings highlight the importance of urban design to prevent and potentially manage metabolic syndrome and improve population health.
Revealing the widespread existence and serious adverse health consequences of low-price rental housing in urban villages in Xiamen, China

AbstractXiamen, China, currently experiencing rapid development, needs to house large numbers of migrant workers who receive relatively low pay, prompting original residents in urban villages to repurpose and rebuild their original houses for low-price letting. In this conglomerate study, we firstly gauged the scale of existence of low-price rental housing (LPRH) in the city’s rental housing market and the severity of their indoor environmental deficiencies. Questionnaires were then employed to reveal the actual living experience of their renters and the consequences on their health. Finally, statistical analyses were used to find the origin of any reported health problems. It was found that partitioned rural rental housings (PRRHs), the specific type of LPRH developed in Xiamen, represented the majority of rental housing supply in most areas of the city, and that the indoor environment parameters were mostly negative, both from the on-site measurements and from renters’ experience. The sub-standard environmental parameters also showed correlational relationships to the renters’ health. This research highlights the significant presence of PRRHs in Xiamen and their disservice for renters’ health, calling governmental intervention throughout the lifetime of LPRHs in all cities including formulating adequate housing plans to house population explosions and renovating and replacing existing LPRHs.
Comparison of soil analytical methods for estimating plant-available potassium in highly weathered soils

Published: July 2023

Context The NaHCO3-extractable soil K test (Colwell K) is the most frequently used method for soil K across Australia, but there is still uncertainty about the suitability of K testing guidelines for heavy-textured soils. Aims To determine whether Colwell K is suitable for predicting plant-available K on loam- and clay-textured soil types developed from highly weathered soil parent materials in Western Australia (WA). Methods Nine soil K testing methods were used to determine plant-available K on 21 soil types with a wide range of properties collected from three depths on the northern, central and southern farmlands in WA. Key results Quartz and K-feldspars were the dominant minerals in all soils, while limited white mica (1–2%) was identified in less than 10% of samples. The amount of K extracted by silver thiourea was only about 70% of the amounts extracted by NaHCO3 (Colwell K) and NH4OAc. Soil non-exchangeable K extracted by nitric acid and sodium tetraphenyl borate were from similar K pools, while aqua regia K was 1–6 times higher than these values. Conclusion There was no systemic difference or proportional bias between NH4OAc K and Colwell K, and both had good model performance (R2 > 0.86) for total K uptake by wheat in a single growing season in a wide range of soils. Implication In this diverse range of soils formed from weathered parent materials, the reliance on exchangeable K for plant K uptake suggests that plant-available K will be vulnerable to rundown due to negative K balances.
Angular correlations on causally-coherent inflationary horizons
Authors: Hogan Craig , Meyer Stephan S , Selub Nathaniel , Wehlen Frederick 
Published: July 2023

Abstract
We develop a model for correlations of cosmic microwave background (CMB) anisotropy on the largest angular scales, based on standard causal geometrical relationships in slow-roll inflation. Unlike standard models based on quantized field modes, it describes perturbations with nonlocal directional coherence on spherical boundaries of causal diamonds. Causal constraints reduce the number of independent degrees of freedom, impose new angular symmetries, and eliminate cosmic variance for purely angular 2-point correlations. Distortions of causal structure from vacuum fluctuations are modeled as gravitational memory from randomly oriented outgoing and incoming gravitational null shocks, with nonlocally coherent directional displacements on curved surfaces of causal diamonds formed by standard inflationary horizons. The angular distribution is determined by axially symmetric shock displacements on circular intersections of the comoving sphere that represents the CMB photosphere with other inflationary horizons—those centered on it, and those that pass through an observer’s world line. Displacements on thin spheres at the end of inflation have a unique angular power spectrum

A new medium-long term polar motion prediction method based on sliding average within difference series
Authors: Wang Leyang , Miao Wei , Wu Fei 
Published: July 2023

Abstract
In response to the problem that the input data and combination method of existing polar motion (PM) prediction methods are relatively single, which leads to the limited satisfaction of PM prediction accuracy by major satellite navigation orbiting systems and deep space exploration projects. This study borrows the idea of differential method and proposes to push back the forecast after selecting several samples within the PM Y, X and Y–X series by sliding average. In the constructed new series, the high-frequency terms are effectively attenuated. Then, the pushing back forecasts are combined in pairs with those of the traditional method. After least-squares extrapolation and autoregressive (LS + AR) modeling, the optimal combination was found. Among them, the prediction of PMX is obtained by subtracting the forecast of PMY of traditional method and the prediction of PM(Y–X) of the sliding average method, the forecast of PMY is obtained by adding the forecast of PMX of the sliding average method and the forecast of PM(Y–X) of the traditional method. The results of the 418-week hindcast experiment from 2012 to 2021 show that the proposed method has a greater improvement than the traditional method, and the corresponding 1–365-day mean absolute error (MAE) are improved by 31.46% and 21.11%, respectively, on average. It has certain advantages over the IERS Bulletin-A in the medium-long term, and the 150-day lead time predictions, the MAE of PMX and PMY were 14.678 and 17.232 mas, respectively, which were less than the 17.833 and 20.769 mas predicted by IERS Bulletin A. This not only verifies that the stability and ability of the proposed method have some competitive ability, but also provides new ideas for other time-series forecasting studies.
Modal frequencies evaluation of a damaged bridge using RCVMD algorithm based on sensor dynamic responses

Published: July 2023

Abstract
This paper aims to employ high-rate global navigation satellite system real-time kinematic (GNSS-RTK) and triaxial accelerometer sensors to evaluate the modal frequencies of a damaged long-span bridge based on the proposed modified variational mode decomposition algorithm. Firstly, in the modified VMD, the relative root mean square error was presented to optimize the decomposition parameter K, the correlation criterion was introduced to select the suitable intrinsic mode function components. The above procedure is called the RCVMD algorithm. Subsequently, the performance comparison evaluation experiments proved that the RCVMD algorithm was more advantageous in the decomposition and reconstruction of signals, had a better noise reduction effect in the signal with different noise levels, and was suitable to process the actual measurement response. Finally, in the field experiment, the modal frequencies of the damaged bridge were correctly detected from the GNSS-RTK displacement and acceleration responses according to the RCVMD algorithm, and the accelerometer picked up the high-order structural frequencies, demonstrating the reliability of the proposed method. The frequency characteristics of the damaged bridge are different from the normal state. The first and third-order frequencies increase, which is especially obvious in the first-order frequency, yet the second-order frequency decreases. The measured results have practical applications and can provide data support for the maintenance of the damaged bridge.

Abstract
Climate change has spurred a shift to electric transportation, but aviation faces challenges with electric energy storage and propulsion. Cryogenically cooled superconducting motors, along with cryogenically cooled power electronics, offer a solution to increase the efficiency and power density of electric aircraft. This paper evaluates the feasibility of cryogenic power electronics by characterising new technologies (GaN, nanocrystalline) using new experimental techniques. It is found that the on resistance reductions of GaN E-high electron mobility transistors at cryogenic temperatures depend on the maximum blocking voltage of the device, and the size of the gate resistor for ohmic p-GaN devices. Different types of nanocrystalline cores are shown to vary greatly in their behaviour at cryogenic temperatures, which is measured using a modified core loss measurement circuit. Further analysis shows that the losses of a GaN based cryogenic inverter could potentially halve that of an equivalent Si based inverter.

Published: July 2023

Abstract
Quantum contextuality is one of the most recognized resources in quantum communication and computing scenarios. We provide a new quantifier of this resource, the rank of contextuality (RC). We define RC as the minimum number of non-contextual behaviors that are needed to simulate a contextual behavior. We show that the logarithm of RC is a natural contextuality measure satisfying several properties considered in the spirit of the resource-theoretic approach. The properties include faithfulness, monotonicity, and additivity under tensor product. We also give examples of how to construct contextual behaviors with an arbitrary value of RC exhibiting a natural connection between this quantifier and the arboricity of an underlying hypergraph. We also discuss exemplary areas of research in which the new measure appears as a natural quantifier.
Electronic phase transition, perpendicular magnetic anisotropy and high Curie temperature in Janus FeClF

Published: July 2023

Abstract
How to enhance the spin polarization, the Curie temperature and the perpendicular magnetic anisotropy (PMA) is crucial for the applications of 2D magnets in spintronic devices. In this work, based on the experimental FeCl2 flakes and the predicted in-plane magnetic anisotropy (IMA) and lower Curie temperature of FeCl2 monolayer, we use first-principles and Monte Carlo simulation to explore the strain and carrier-doping effects on the electronic and magnetic properties of Janus FeClF monolayer. The structure is stable within −10% to 2% biaxial strain. Janus FeClF monolayer can experience transitions from a half-semiconductor to a spin gapless semiconductor (SGS) around the −6% compressive strain, and from the IMA to the PMA at the −7% compressive strain. The super-exchange Fe–F/Cl–Fe interaction induces the ferromagnetic coupling, and the Curie temperature can be considerably enhanced from 56 K to 281 K at the −10% compressive strain. The half-metallicity can be achieved whether under electron doping or hole doping. The Fe-d orbitals and the spin–orbit coupling interaction between occupied and unoccupied intraorbital states are responsible for the electronic phase transition and the magnetic anisotropy, respectively. Remarkably, the compressive −10% strain and the 0.02 e doping collectively increase the Curie temperature to near room temperature (286 K). The high spin polarization (exhibiting SGS and half-metal), the PMA and the near-room-temperature ferromagnetism induced by strain and doping make Janus FeClF a promising candidate for 2D spintronic applications, which will stimulate experimental and theoretical broad studies on this class of Janus monolayers FeXY (X,Y = F, Cl, Br, and X ≠ Y).
