Published: September 2021

AbstractA key open question in the aerial locating method is ensure that parameters that identify the location of the radio frequency interference (RFI) are monitored, and to make sure that the locating algorithm is unbiased. Furthermore, the transmission of parameters to the ground for real-time analysis and display of the RFI location is important as it provides insight into the performance advantages of the aerial location method. The main contributions of the article are four points: the first is the introduction of the angle of arrival (AOA) algorithm to civil aviation RFI location, and the integration of algorithm characteristics with unmanned aerial vehicle (UAV) operations proposing an aerial monitoring method for civil aviation RFI. Simulation results show that the two-point cross-location method obtains effective information on the location parameters of the RFI. The second is to build a UAV monitoring platform, which is as light as possible to make sure the direction finding and digital transmission devices meet the airworthiness requirements, so that the UAV can complete the data acquisition task within a safety margin. Thirdly, a ground analysis system was designed to receive information on the UAV’s parameters, enabling software manipulation to ensure safe operation under non-visual conditions. In addition to this, the monitoring data is processed in real time and algorithms are used to resolve the location of interference sources and display them on a map. The fourth one is to verify the implementation of the aerial positioning method by setting up different test scenarios. Compared with portable direction-finding equipment and ground monitoring, the test results show that the UAV-based RFI monitoring method performances better in monitoring radius and positioning accuracy with a small direction-finding error, and the advantages of the ground analysis system are highly integrated and intuitive display.

Published: September 2021

AbstractBalancing agendas for climate mitigation and environmental justice continues to be one of the key challenges in climate change governance mechanisms, such as Reducing Emissions from Deforestation and Degradation (REDD+). In this paper we apply the three-dimensional environmental justice framework as a lens to examine the REDD+ process in the Lao People’s Democratic Republic (Laos) and the REDD+ social safeguards. We focus particularly on challenges to justice faced by marginalized communities living in forest frontier areas under an authoritarian regime. Drawing on policy analysis and open-ended interviews across different policy levels, we explore procedural, distributional, and recognitional justice across the REDD+ policy levels in Laos. We find that REDD+ social safeguards have been applied by both donors and state actors in ways that facilitate external control. We underscore how authoritarian regime control over civil society and ethnic minority groups thwarts justice. We also highlight how this political culture and lack of inclusiveness are used by donors and project managers to implement their projects with little political debate. Further obstacles to justice relate to limitations inherent in the REDD+ instrument, including tight schedules for dealing with highly sensitive socio-political issues under social safeguards. These findings echo other research but go further in questioning the adequacy of safeguards to promote justice under a nationally driven REDD+. We highlight the importance of recognition and political context, including aspects such as power relations, self-determination and self-governance of traditional or customary structures, in shaping justice outcomes.
A Boundary Tool for Multi-stakeholder Sustainable Business Model Innovation
Authors: Velter M. G. E. , Bitzer V. , Bocken N. M. P. 
Published: September 2021

AbstractSustainable business model innovation cannot reach its full sustainability potential if it neglects the importance of multi-stakeholder alignment. Several studies emphasize the need for multi-stakeholder collaboration to enable sustainable business model innovation, but few studies offer guidance to companies for engaging in such a collaborative process. Based on the concept of boundary work, this study presents a tested process tool that helps companies engage with multiple stakeholders to innovate sustainable business models. The tool was developed in three iterative phases, including testing and evaluation with 74 participants in six sustainable business model innovation cases. The final process tool consists of five steps to facilitate multi-stakeholder alignment for sustainable business model innovation: (1) defining a collective ambition, (2) mapping and negotiating the changing organizational boundaries, (3) exploring opportunities and tensions for aligning stakeholders, (4) defining first interventions and (5) developing a collaboration pitch. We found that the tool enables discussions and negotiations on sensitive topics, such as power reconfigurations and mutual responsibilities to help stakeholders align. For companies, the boundary tool enriches sustainable business model innovation by offering guidance in the process of redesigning their multi-stakeholder system, assessing their own organizational boundaries, exploring, negotiating and prioritizing strategic actions based on organizational boundary changes and kick-starting new partnerships.

Published: September 2021

Abstract

Introduction
Chronic vulvar pain is a condition that affects many women during their lifetime, including women with Female Genital Mutilation/Cutting (FGM/C).

Aim
To study the prevalence and possible etiologies of chronic vulvar pain among women living with FGM/C.

Methods
We conducted a retrospective review of consecutive medical files of 506 women who consulted our specialized clinic for women with FGM/C between April 1, 2010 and December 31, 2017. We collected sociodemographic and clinical data including information on the type of FGM/C and its complications. We focused on studying the prevalence, etiologies and characteristics of chronic vulvar pain.

Main outcome measures
Prevalence and etiologies of vulvar pain in women with FGM/C.

Results
Chronic vulvar pain was present in 14 women (2.8%). Pain was unprovoked in one case (7.1%) and provoked in the 13 other cases (92.9%). In most of the cases, women presented vulvar pain related to scar complications such as clitoral or peri-clitoral adhesions or scar tissue (n = 3, 21.4%), bridle scars (n = 1, 7.1%), post-traumatic neuromas (n = 2, 14.3%) and vulvar cysts (n = 6, 42.9%), the latter being found more frequently in women with FGM/C type III. In 2 cases (14.3%) of chronic vulvar pain, no lesions other than FGM/C were visible at clinical examination. Among these 14 women, 12 suffered from superficial dyspareunia as well. The remaining ones had not had any sexual contact for several years.
Dyspareunia was present in 126 women (24.9%), among which 75 patients (14.8%) suffered from superficial dyspareunia and 25 patients (4.9%) complained of deep dyspareunia. Fourteen women (2.8%) reported both superficial and deep dyspareunia. Twelve women (2.3%) reported dyspareunia with no specified localization documented in the medical charts. Dyspareunia was significantly more frequent among infibulated women compared to women with FGM/C different from type III (P = .014).

Conclusion
Chronic vulvar pain after FGM/C is probably associated with scar complications and FGM/C type III (infibulation). Dyspareunia is more frequent in women with FGM/C type III.

Published: September 2021

ABSTRACT

Introduction:
Safe entry zone for brain stem surgery has already been established. Selective approaches or routes can be used according to anatomical locations. Appropriate surgical corridors for Brainstem Cavernous Malformations (CM) are critical where neuronavigation is not available. Preoperative GCS, comorbid conditions, and patient's age are strong predictors of the outcome of the surgery.

Objective:
The study aims to assess the surgical outcome of the brainstem CM.

Method:
A total of eight patients were observed retrospectively from 2013 to 2017 in a private hospital in Dhaka, Bangladesh, of which the male: female ratio was 3:2. Four patients underwent surgeries, and four patients were treated without surgery. Multiple variables, including preoperative GCS, age of the patient, and comorbid conditions, were analyzed. Operative procedures were analyzed in detail. The patient's symptoms and signs, the timing of surgery, and recurrent hemorrhage were observed.

Results:
Out of four (4) surgical patients-1 died due to pneumonia after two months of surgery. One patient developed internuclear ophthalmoplegia immediately after surgery and recovered after two months. 2 patients recovered entirely, of which one developed obstructive hydrocephalus and was managed by endoscopic third ventriculostomy.

Conclusion:
Safety corridors for brainstem CM are to be selected according to the location of the lesions. Preoperative patient status, appropriate patient selection, and perioperative management of the patients are few predictors of surgical outcomes. Making a pseudo plane in removing CM with sharp microdissection is technically helpful even in adhering lesions.

Abstract
Consumption of pork and pork products can be associated with outbreaks of human salmonellosis. Salmonella infection is usually subclinical in pigs, and farm-based control measures are challenging to implement. To obtain data on Salmonella prevalence, samples can be collected from pigs during the slaughter process. Here we report the results of a Great Britain (GB) based abattoir survey conducted by sampling caecal contents from pigs in nine British pig abattoirs during 2019. Samples were collected according to a randomised stratified scheme, and pigs originating from 286 GB farms were included in this survey. Salmonella was isolated from 112 pig caecal samples; a prevalence of 32.2% [95% confidence interval (CI) 27.4–37.4]. Twelve different Salmonella serovars were isolated, with the most common serovars being S. 4,[5],12:i:-, a monophasic variant of Salmonella Typhimurium (36.6% of Salmonella-positive samples), followed by S. Derby (25.9% of Salmonella-positive samples). There was no significant difference compared to the estimate of overall prevalence (30.5% (95% CI 26.5–34.6)) obtained in the last abattoir survey conducted in the UK (2013). Abattoir-based control measures are often effective in the reduction of Salmonella contamination of carcasses entering the food chain. In this study, the effect of abattoir hygiene practices on the prevalence of Salmonella on carcasses was not assessed. Continuing Salmonella surveillance at slaughter is recommended to assess effect of farm-based and abattoir-based interventions and to monitor potential public health risk associated with consumption of Salmonella-contaminated pork products.
Price promotion of organic foods and consumer demand

Published: September 2021

AbstractExisting studies have examined the demand elasticities for organic products only in select categories, and their results for consumers' sensitivity to price changes are inconsistent. Evidence regarding the effects of price promotions on the demand for organic foods vs non-organic foods is scarce. This study aims to (1) examine the own-price elasticities of organic foods vs non-organic counterparts both with and without a promotion in a variety of product categories, and (2) investigate how the distinctive promotion effects between organic and non-organic counterparts depend on food category features. Using purchase data for 36 food categories from the 2015 Nielsen Consumer Panel, we find differential own-price elasticities for organic and non-organic foods, regardless of whether the product is purchased with a promotion. When the products are purchased with a promotion, we find stronger price promotion effects of organic virtues than non-organic virtues and weaker price promotion effects of organic vices than conventional vices. Price promotions of organic foods are more likely to induce health-conscious consumers to switch from conventional purchases to organic purchases in virtues.

Published: September 2021

AbstractAccurate and efficient quantum control in the presence of constraints and decoherence is a requirement and a challenge in quantum information processing. Shortcuts to adiabaticity, originally proposed to speed up the slow adiabatic process, have nowadays become versatile toolboxes for preparing states or controlling the quantum dynamics. Unique shortcut designs are required for each quantum system with intrinsic physical constraints, imperfections, and noise. Here, we implement fast and robust control for the state preparation and state engineering in a rare-earth ions system. Specifically, the interacting pulses are inversely engineered and further optimized with respect to inhomogeneities of the ensemble and the unwanted interaction with other qubits. We demonstrate that our protocols surpass the conventional adiabatic schemes, by reducing the decoherence from the excited-state decay and inhomogeneous broadening. The results presented here are applicable to other noisy intermediate-scale quantum systems.

AbstractThis study aimed to analyze fragments of rangelands through spectral responses and land cover change by livestock in regions of the Caatinga biome through remote sensing. For spectral behavior, the surface reflectance bidirectional (SRB) and spectral indexes of vegetation were used to verify the ragelands seasonality. Land cover change detection of Ouricuri and Tauá through Landsat-8 images with a 16-day revisit interval, were processed in the Google Earth Engine platform (GEE) and software Quantum GIS version 2.18 (QGIS). In the GEE platform, annual mosaics and stacking of the spectral bands were generated for the classification of images, and in sequence the production of thematic maps in QGIS. The analysis of land cover change considered the classes: thinned Caatinga, conserved Caatinga, herbaceous vegetation, bare soil, water and others. The analysis of the spectral responses showed that the vegetation monitored in Ouricuri presented higher SRB in the infrared band and lower SRB in the red and blue bands, and that caused the pasture to produce higher vegetation indexes than the other locations. Through validation, it was observed that in Tauá, there was an overall accuracy of 91% and Kappa index of 89%, and in Ouricuri there was an overall accuracy of 90% and Kappa index of 86%, indicating excellent correctness of the classification model. The classification model proved to be effective in verifying the temporal and spatial land cover change, making it possible to identify places with the vegetation that was most affected and susceptible to degradation and generation of political support to minimize damage to the Caatinga Biome.

Context. The Vela complex is a region of the sky that gathers several stellar and interstellar structures in a few hundred square degrees.
Aims.Gaia data now allow us to obtain a 3D view of the Vela interstellar structures through the dust extinction.
Methods. We used the FEDReD (Field Extinction-Distance Relation Deconvolver) algorithm on near-infrared 2MASS data, cross-matched with the Gaia DR2 catalogue, to obtain a 3D cube of extinction density. We applied the FellWalker algorithm to this cube to locate clumps and dense structures.
Results. We analysed 18 million stars over 450 deg2 to obtain the extinction density of the Vela complex from 0.5 to 8 kpc at ℓ ∈ [250° ,280° ] and b ∈ [ − 10° ,5° ]. This cube reveals the complete morphology of known structures and relations between them. In particular, we show that the Vela Molecular Ridge is more likely composed of three substructures instead of four, as suggested by the 2D densities. These substructures form the shell of a large cavity. This cavity is visually aligned with the Vela supernova remnant but located at a greater distance. We provide a catalogue of location, distance, size, and total dust content of Interstellar Medium (ISM).
The bi-modal 7Li distribution of the Milky Way’s thin-disk dwarf stars
Authors: Roca-Fàbrega S. , Llorente de Andrés F. , Chavero C. , Cifuentes C. , de la Reza R. 
Published: September 2021

Context. The lithium abundance, A(Li), in stellar atmospheres suffers from various enhancement and depletion processes during the star’s lifetime. While several studies have demonstrated that these processes are linked to the physics of stellar formation and evolution, the role that Galactic-scale events play in the galactic A(Li) evolution is not yet well understood.
Aims. We aim to demonstrate that the observed A(Li) bi-modal distribution, in particular in the FGK-dwarf population, is not a statistical artefact and that the two populations connect through a region with a low number of stars. We also want to investigate the role that Galactic-scale events play in shaping the A(Li) distribution of stars in the thin disk.
Methods. We use statistical techniques along with a Galactic chemical evolution model for A(Li) that includes most of the well-known 7Li production and depletion channels.
Results. We confirm that the FGK main-sequence stars belonging to the Milky Way’s thin disk present a bi-modal A(Li) distribution. We demonstrate that this bi-modality can be generated by a particular Milky Way star formation history profile combined with the stellar evolution’s 7Li depletion mechanisms. We show that A(Li) evolution can be used as an additional proxy for the star formation history of our Galaxy.

Zusammenfassung
Anamnese und klinischer Befund Wir berichten über eine 89-jährige Patientin, für die aufgrund einer Bewusstseinsstörung der Notarzt alarmiert wurde. Sie war soporös und zeigte eine deutliche generalisierte Muskelrigidität. Fremdanamnestisch war der fehlerhafte Gebrauch eines Fentanyl-Pflasters zu eruieren.
Therapie und Verlauf Durch die Antidot-Gabe von Naloxon kam es zu einer Restitution. Die Notwendigkeit einer repetitiven Gabe bestätigte die Verdachtsdiagnose.
Folgerung Die Gabe von Fentanyl über die Haut in Form transdermaler therapeutischer Systeme (TTS) erfreut sich seit Jahren einer zunehmenden Beliebtheit. Bei unsachgemäßer Verabreichung treten Intoxikationen mit den führenden Symptomen Bewusstseinsminderung und Atemdepression auf. Dieser Fallbericht ergänzt das Spektrum um den Rigor der quergestreiften Skelettmuskulatur, der sonst im Zusammenhang mit der intravenösen Applikation beschrieben wird.

Resumo
Objetivo Comparar a dor, a função, a qualidade de vida e os eventos adversos da descompressão lombar e da fusão espinhal em pacientes com patologias degenerativas da coluna vertebral que participaram de um programa de segunda opinião para cirurgias de coluna com acompanhamento de 36 meses.
Métodos Os dados desta coorte retrospectiva foram obtidos de um sistema de saúde privado entre junho de 2011 e janeiro de 2014. A amostra do estudo foi composta por 71 pacientes encaminhados para cirurgia de coluna lombar. Os desfechos para comparações entre a descompressão lombar e a fusão espinhal foram qualidade de vida (avaliada pelo questionário EuroQoL 5D), dor (medida pela Escala Numérica de Classificação de Dor) e função (avaliada pelo Questionário de Incapacidade de Roland Morris) no início do estudo e aos 12 e 36 meses de acompanhamento pós-cirúrgico. As definições de recuperação foram estabelecidas pela diferença mínima clinicamente importante (DMCI). As diferenças basais entre os grupos foram analisadas por teste t não pareado, e as diferenças nas pontuações dos instrumentos entre os momentos, por modelos mistos generalizados. Os resultados foram apresentados como valores médios ajustados pelos modelos e intervalos de confiança de 95%.
Resultados No total, 22 pacientes foram submetidos à artrodese, e 49 pacientes, à descompressão lombar. Quanto às comparações de achados antes e depois das intervenções cirúrgicas, a DMCI foi alcançada em todos os desfechos de qualidade de vida, dor e função nos dois pontos de acompanhamento em relação aos escores basais Em relação às complicações, apenas a descompressão lombar apresentou 4% (n = 3) de taxa cirúrgica de recidiva da hérnia de disco lombar.
Conclusão Pacientes com patologias espinhais degenerativas apresentam melhoras nos desfechos de dor, função e qualidade de vida em longo prazo que são clinicamente significativas e independentes da intervenção cirúrgica.
