Summer seasonal prevalence of Culicoides species from pre‐alpine areas in Switzerland
Authors: Paslaru A. I. , Torgerson P. R. , Veronesi E. 
Published: December 2020

AbstractBiting midges (Diptera: Ceratopogonidae) are arthropods of veterinary importance since they can transmit pathogens and cause severe allergic dermatitis in horses. Very little is known about the species at higher altitudes and their seasonal dynamics. In this work, adult Culicoides were collected with Onderstepoort UV‐light suction traps (OVI) from June to September 2016 at two areas situated at around 1600 m asl (pre‐alpine area I, 2 farms) and 2030 m asl (pre‐alpine area II, 1 farm) in the Canton of Grisons (south‐east Switzerland). Overall, 17 049 Culicoides were collected, including 871 parous females. A total of 50 individuals/trap/night (n = 1050) were identified to species (17 species) by matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOF MS) or by polymerase chain reaction (PCR) and sequencing. The remaining 15 128 Culicoides were classified to species groups' level. Culicoides obsoletus (Meigen, 1818), a multivoltine species, was mainly present at 1600 m asl, whereas at high altitudes (2030 m asl), C. grisescens Edwards, 1939 I&II were the most abundant species. In particular, C. grisescens II, which seems to be univoltine, occurred later in the season but significantly increasing over time. Species diversity was higher at pre‐alpine I area (n = 16 species) compared to pre‐alpine II (n = 10 species).
On how trap positioning affects phlebotomine sand fly density estimations
Authors: Muñoz C. , Pérez‐Cutillas P. , Berriatua E. , Ortiz J. 
Published: December 2020

AbstractThere is a need for standardizing sand fly sampling methodology and guidance on trap positioning for quantitative sand fly studies. We investigated differences in sand fly density with ‘sticky’ interception and CO2‐light attraction traps, in relation to trap distance to the ground and the presence or absence of a continuous or discontinuous (wire mesh) vertical surface adjacent to the trap. The study, conducted in a dog kennel in southeast Spain, lasted 48 days and collected 692 Phlebotomus papatasi, P. perniciosus, P. ariasi and Sergentomyia minuta specimens. There were no significant differences between species with respect to trap position. Overall, density in sticky traps was highest closest to the ground and next to the continuous vertical surface, followed sequentially by traps similarly placed adjacent to the wire mesh and those hanging from a rope across the kennel yard. In contrast, density in CO2‐light traps was highest in traps hanging from the rope near the ground, followed by those next to the continuous vertical surface. The overall negative relationship between sand fly density and ground distance was not significant for CO2‐light traps next to the continuous vertical surface. Modelling also suggested that sand flies do not use the wire mesh to move vertically.
Disciplinary Potential and Individual Choice: Reflections from Participatory Research on Oaxacan Intercultural Education
Authors: Lebrato Matthew 
Published: December 2020

AbstractThis article reflects on the current status of participatory research in anthropology. I draw on my work at the Instituto Superior Intercultural Ayuuk (Ayuuk Intercultural University) in Oaxaca, Mexico to sketch some of potentials and pitfalls for participatory research during the preliminary, data‐collection, and postfield phases. My argument is that while anthropologists as individuals tend to find ways to connect meaningfully with collaborators in the field, the discipline does little to train, foster, or evaluate participatory research as a core element. Assigning participatory research to the status of a personal choice rather than a disciplinary hallmark saps anthropology's potential for meaningful engagement with a host of publics, not the least of which are the communities, groups, and networks of individuals with whom we conduct research.

Summary

The tree seed mycobiome has received little attention despite its potential role in forest regeneration and health. The aim of the present study was to analyze the processes shaping the composition of seed fungal communities in natural forests as seeds transition from the mother plant to the ground for establishment.

We used metabarcoding approaches and confocal microscopy to analyze the fungal communities of seeds collected in the canopy and on the ground in four natural populations of sessile oak (Quercus petraea). Ecological processes shaping the seed mycobiome were inferred using joint species distribution models.

Fungi were present in seed internal tissues, including the embryo. The seed mycobiome differed among oak populations and trees within the same population. Its composition was largely influenced by the mother, with weak significant environmental influences. The models also revealed several probable interactions among fungal pathogens and mycoparasites.

Our results demonstrate that maternal effects, environmental filtering and biotic interactions all shape the seed mycobiome of sessile oak. They provide a starting point for future research aimed at understanding how maternal genes and environments interact to control the vertical transmission of fungal species that could then influence seed dispersal and germination, and seedling recruitment.
Orofacial clefts in low‐ and middle‐income countries: A scoping review of quality and quantity of research based on literature between 2010‐2019

Published: December 2020

Structured AbstractThis paper assesses the research literature on OFC in LMIC over the last decade across various geographical settings and project focus of the indexed literature. A scoping review of the indexed literature was performed using a set of predefined keywords. The articles were filtered by a ten‐year time frame (2010‐2019) and a strict inclusive‐exclusive criterion. Two authors screened the titles/abstracts/full text of the final included papers and input the desired data (year of publication, type of publication, geographical country/region and project focus to a coded spreadsheet). Six hundred and twenty publications were inventoried from the indexed literature on OFC in LMIC settings over the 10‐year period. Five hundred and eighty‐three derived from single LMIC countries and 37 from multi‐settings. More than half of the articles were reported from Asia (57%), then from Americas (22.8%), Africa (15.4%) and the rest from cross‐regional, Europe and Oceania (4.9%). The top 3 LMIC contributors towards OFC publications were China (21.5%), Brazil (13.1%) and India (11.6%). The most discussed OFC project themes were prevalence, surgical repair, aetiology and genetics. This study helps OFC researchers, humanitarian missions and research grant funders to identify gaps in the literature on issues impacting on children and adults born with OFC, in which issues were subjected to research and which were less explored in which LMIC regions. In addition, this study offers recommendations for established OFC researchers and international research bodies to identify areas of deficiency in the literature and what information is required to support LMIC governments achieve SDGs by 2030.

Published: December 2020

AbstractTo ensure an adequate pain therapy with high patient adherence, it is necessary to know and consider patient preferences. A discrete choice experiment was used to obtain patients’ preferences regarding treatment with systemic or topical pain medication. Patients with peripheral neuropathic pain (pNP) were recruited in two pain‐focused practices in Germany. To identify relevant attributes of topical or systemic pain medication, a literature review and face‐to‐face interviews with experts for pain treatment were conducted. The attributes used in the choice scenarios were noticeable onset of effect, time spent in medical office, risk of systemic and local side effects, and impairment of daily life with regard to sleep quality and sexuality. The model was estimated with a mixed multinomial logit regression model. The study included 153 participants suffering from moderate to severe pNP. Most important attributes from patient’s perspective was noticeable onset of effect (odds ratio 2.141 [95% confidence interval 1.837 to 2.494]), followed by risk of systemic side effects (2.038 [1.731 to 2.400]) and risk of sexual dysfunction (1.839 [1.580 to 2.140]), while risk of local side effects regarding skin ranked fourth (1.612 [1.321 to 1.966]). The impairment of sleep quality was also significant but less important (1.556 [1.346 to 1.798]). Local side effects were more likely to be accepted than systemic side effects. The risk of sexual dysfunction as a side effect of treatment is very important for patients, although it has received little attention in the literature.

Published: December 2020

AbstractObjectiveTo assess propranolol's impact on sleep when used in infants and toddlers with infantile hemangioma (80% under 6 months old).MethodsParents and caregivers of infants and toddlers with infantile hemangioma presenting to a tertiary pediatric hospital's dermatology clinic and assessed by their dermatologist as requiring propranolol treatment were invited to participate. All participants completed an extended version of the Brief Infant Sleep Questionnaire (BISQ) prior to propranolol treatment initiation, which acted as the control, and 5 weeks after treatment commencement. Objective data were gathered through actigraphy, which utilizes a small wristwatch‐like device that measures sleep‐wake patterns, for 1 week prior to initiation and again 5 weeks after commencement. BISQ responses and actigraphy values from the two time points were compared.Results55 infants and toddlers (aged 0‐2.8 years, 80% under 6 months) were included. Sleep was reported as only a minor problem by most parents 5 weeks after starting propranolol (P = .049). Subgroup analysis of 45 infants <6 months old showed no significant difference in sleep while taking propranolol. Whole cohort BISQ data analysis showed a statistically significant increase in night‐time sleep (P = .024), and a decrease in the number (P = .003) and duration of daytime naps (P = .025) following commencement of propranolol. Actigraphy data completed in 10 infants showed no significant difference in sleep quality before and 5 weeks after commencing propranolol.ConclusionPropranolol did not significantly impair sleep quality and pattern in our cohort of infants and toddlers with infantile hemangioma. Most parents considered the impact on sleep to be only a minor problem.
Survivors of allogeneic bone marrow transplants in childhood report no significant long‐term respiratory symptoms: A single‐center analysis over 20 years
Authors: Ball Jessica , Growcott Siona , Cameron Alison 
Published: December 2020

AbstractPulmonary toxicity is documented in long‐term survivors of allogeneic BMT. No studies have specifically evaluated late pulmonary symptomatology in these patients. 85 long‐term pediatric survivors were sent a validated questionnaire of pulmonary symptomatology. Demographic and clinical data were retrospectively collected from the respondents medical records. Response rate was 52.9%. Mean follow‐up post‐BMT of those who responded was 12.3 years. Mean pulmonary symptom scores were low (0.78). There was no significant difference in symptoms between patients who underwent MA conditioning with or without TBI. These results are reassuring that long‐term survivors of pediatric BMT have few respiratory symptoms which do not impact on activities of daily living.
Cultivating Justice beyond Law
Authors: Bocarejo Diana 
Published: December 2020

AbstractThinking about justice beyond law involves understanding justice as a process thatcampesinos(peasants) in Colombia link to aspirations for a good life. I argue that environmental justice draws on distinctive temporalities and spatial scales. By temporality, I refer to how campesinos think about justice as a process to overcome their long history of community injustice, not as a reversal of a single event or action. I also refer to campesinos’ everyday life, through which they define the territorial management underlying their enduring social inequality. Justice does not entail fixed spatial scales but rather the interplay between forms of state and local spatial orderings that may clash or coexist. These spatial‐temporal dimensions have crucial consequences for addressing environmental justice, such as redress beyond individual compensation; thinking about scale beyond legal frameworks of jurisdiction; reflecting on the unequal distribution of responsibilities for environmental changes; and addressing notions of response‐ability—that is, the capacity of campesinos to respond, not only to react, with both patience and urgency to socio‐environmental harms.
Asymmetric expression patterns of B‐ and C‐class MADS‐box genes correspond to the asymmetrically specified androecial identities of Canna indica
Authors: Tian X. , Li X. , Yu Q. , Zhao H. , Liao J. 
Published: December 2020

Abstract

Canna indica is a common ornamental plant with asymmetric flowers having colourful petaloid staminodes. The only fertile stamen comprises a one‐theca anther and a petaloid appendage and represents the lowest stamen number in the order Zingiberales. The molecular mechanism for the asymmetric androecial petaloidy remains poorly understood. Here, we studied the identity specification in Canna stamen.

We observed four types of abnormal flower in terms of androecium identity transformation and analysed the corresponding floral symmetry changes. We further tested the expression patterns of B‐ and C‐class MADS‐box genes using in situ hybridization in normal Canna stamen.

Homeotic conversions in the androecium were accompanied by floral symmetry changes, and the asymmetric stamen is key in contributing to the floral asymmetry. Both B‐ and C‐class genes exhibited higher expression levels in the anther primordium than in other androecial parts. This asymmetric expression pattern precisely corresponded to the asymmetric identities of the Canna androecium.

We identified C. indica as a model species for studying androecial organ identity and floral symmetry synthetically in Zingiberales. We hypothesized that homeotic genes specify floral organ identity in a putative dose‐dependent manner. The results add to the current understanding of organ identity‐related floral symmetry.
The cross‐kingdom roles of mineral nutrient transporters in plant‐microbe relations

Published: December 2020

AbstractThe regulation of plant physiology by plant mineral nutrient transporter (MNT) is well understood. Recently, the extensive characterization of beneficial and pathogenic plant‐microbe interactions has defined the roles for MNTs in such relationships. In this review, we summarize the roles of diverse nutrient transporters in the symbiotic or pathogenic relationships between plants and microorganisms. In doing so, we highlight how MNTs of plants and microbes can act in a coordinated manner. In symbiotic relationships, MNTs play key roles in the establishment of the interaction between the host plant and rhizobium or mycorrhizae as well in the subsequent coordinated transport of nutrients. Additionally, MNTs may also regulate the colonization or degeneration of symbiotic microorganisms by reflecting the nutrient status of the plant and soil. This allows the host plant obtain nutrients from the soil in the most optimal manner. With pathogenic‐interactions, MNTs influence pathogen proliferation, the efficacy of the host's biochemical defense and related signal transduction mechanisms. We classify the MNT effects in plant‐pathogen interactions as either indirect by influencing the nutrient status and fitness of the pathogen, or direct by initiating host defense mechanisms. While such observations indicate the fundamental importance of MNTs in governing the interactions with a range of microorganisms, further work is needed to develop an integrative understanding of their functions.

Published: December 2020

AbstractCrosstalk between the oocyte and surrounding cumulus cells (CCs) is essential for the production of competent oocytes. Previous studies have analysed the relative transcript abundance in oocytes derived from small (SF: <3 mm diameter)‐ and medium‐sized (MF: 3–6 mm diameter) follicles to determine the potential use of SF‐derived oocytes in assisted reproductive technologies (ART). The aim of this study was to examine the relative transcript abundance of CCs obtained from cumulus–oocyte complexes (COCs) derived from SF and MF. Nine genes were selected according to their importance for developmental competence: AT‐rich interaction domain 1B (ARID1B), bone morphogenic protein receptor 2 (BMPR2), CD44, follicle‐stimulating hormone receptor (FSHR), follistatin (FST), inhibin beta‐A (INHBA), luteinizing hormone receptor (LHR), nuclear receptor subfamily 2 group F member 6 (NR2F6) and vascular endothelial growth factor A (VEGFA). The expression of these genes was analysed by RT‐qPCR. The results pointed to significant differences in five genes, and the relative transcript abundance of SF‐derived CCs was lower in the case of INHBA, but higher in FSHR, FST, LHR and NR2F6 compared with MF‐derived CCs. We provide information of gene activity in the porcine CCs from different sized follicles, thus improving our understanding of oocyte biology and providing new markers that identify viable and competent oocytes.

Published: December 2020

AbstractThe Salt Range in Pakistan exposes Precambrian to Pleistocene strata outcropping along the Salt Range Thrust (SRT). To better understand the in‐situ Cambrian and Pliocene tectonic evolution of the Pakistan Subhimalaya, we have conducted low‐temperature thermochronological analysis using apatite (U‐Th‐Sm)/He and fission track dating. We combine cooling ages from different samples located along the thrust front of the SRT into a thermal model that shows two major cooling events associated with rifting and regional erosion in the Late Palaeozoic and SRT activity since the Pliocene. Our results suggest that the SRT maintained a long‐term average shortening rate of ~5–6 mm/yr and a high exhumation rate above the SRT ramp since ~4 Ma.
Controller Driven VRML Animation of the NIST Robotic Welding Cell
Authors: Stouffer Keith 
Published: December 2020

Abstract
Virtual objects in a web-based environment can be interfaced to and controlled by external real world controllers. A Virtual Reality Modeling Language (VRML) welding cell was created that models a robotic arc welding cell (the Automated Welding Manufacturing System project,) located at the National Institute of Standards and Technology (NIST). The VRML welding cell contains a model of a 7 degree-of-freedom robot, a welding table, torch and various fixtures and parts. The VRML robot is interfaced to, and can be controlled by, the real world robot controller. This is accomplished by a socket connection between the collaborator’s web browser and the real world controller. The current joint angles of the robot, which are stored in a world model buffer in the controller, are collected by a Java applet running on the web page. The applet updates the VRML model of the robot via the External Authoring Interface (EAI) of the VRML plug-in. Virtual welds, a series of VRML cylinders, are also dynamically created every 100 ms on the part based on the current robot position and colored according to the calculated weld quality of that section of weld obtained from the real world controller. This allows a collaborator to visually determine where a bad section of weld has occurred without being present in the physical welding lab.
PC Based Data Acquisition, and Analysis of Fluid Flow Over a Poppet Valve
Authors: Aflaki Jamshid 
Published: December 2020

Abstract
The flow of liquid fuel (hydrogen) and the oxidizing agent in a rocket engine are controlled by valves that are called main feed valves. The most often used type of feed valve is the so-called in-line poppet valve. The pressure drop across the feed valve must be kept as low as possible to avoid cavitation, which may cause interruption of the proper amount of fuel flow. In addition, a controllable motion of the valve poppet during opening/closing of the valve is required to prevent the possibility of a water hammer.
This paper provides an experimental fluid dynamic investigation of a commercial in-line poppet valve. Pressure losses across the valve and drag forces experienced by the valve poppet were measured using approximately 1/2 scale model. The water was used as the flowing medium.
To find a valve design with minimum pressure loss, new valve models were designed and tested. The results of this research can be summarized as follows.
An optimal choice of valve housing contours and valve poppet shapes could decrease the pressure loss coefficient by more than 50%. (typically from ξ = 0.82 to ξ = 0.37). The pressure loss coefficient is strongly dependent on the Reynolds number up to Reynolds numbers of approximately less than 2.5 × 105. The flow force experienced by the valve poppet increases exponentially during closing of the valve.
Strategies for Product Structure Management in Manufacturing Firms
Authors: Svensson Daniel , Malmqvist Johan 
Published: December 2020

Abstract
Product structure management (PSM) is a process that affects many different disciplines in a company. Different disciplines have different demands on the decomposition of the product structure and the functionality of the information systems used. Different disciplines therefore often work in different information systems. If several information systems to some extent contain the same information, it is important that the information is updated in all systems if it is changed. Since PSM is a change intensive activity, it is difficult to perform PSM in an environment consisting of several different information systems.
There is a need for strategies for PSM that considers all relevant aspects of an information system, such as the process it supports, the information handled, the information systems used and the organisation.
This paper discusses different disciplines requirements on the product structure based on a case study at an automotive manufacturing firm. The paper proposes strategies for PSM that can be used as a guide and for categorisation when analysing the information system before restructuring and/or introduction of new systems.
