AbstractObjectiveThis study aimed to evaluate the effectiveness of computed tomography and positron emission tomography-computed tomography prior to salvage surgery after head and neck carcinoma treated with bioradiotherapy and to look at the role of neck dissection in this setting.MethodThis study was a retrospective chart review of a series of consecutive patients with locally advanced head and neck squamous cell carcinoma treated with bioradiotherapy. Radiological and pathological stages were compared to evaluate the accuracy of computed tomography and positron emission tomography-computed tomography in detecting occult neck metastasis in the context of recurrence of primary tumour. In order to assess the impact of neck dissection on survival, Kaplan–Meier survival curves after salvage surgery with and without neck dissection were derived.ResultsA total of 268 patients were identified, of which 22 underwent salvage surgery. The negative predictive value of computed tomography and positron emission tomography-computed tomography was excellent. Neck dissection did not represent an improvement on overall, disease specific and regional recurrence free survival (p =0.67,p =0.91 andp =0.62, respectively) amongst clinically and radiologically negative necks.ConclusionConservative treatment of the neck should be considered when dealing with patients with primary site recurrence or persistent disease after bioradiotherapy without evidence of neck disease.

AbstractObjectiveRecurrent acute otitis media is common in children. The preferred treatment measures for recurrent acute otitis media have a mixed evidence base. This study sought to assess baseline practice across ENT departments in England.MethodsA national telephone survey of healthcare staff was conducted. Every ENT centre in England was contacted. A telephone script was used to ask about antibiotic and grommet use and duration in recurrent acute otitis media cases.ResultsNinety-six centres (74 per cent) provided complete information. Recurrent acute otitis media treatment across England by ENT departments varied. The antibiotic first- and second-line prophylaxis offered varies, with trimethoprim used in 33 centres and 29 centres not offering any antibiotics. The timing or choice about when to use grommets also varies, but 87 centres (91 per cent) offer grommet surgery at one stage.ConclusionThe treatments received by children in England for recurrent acute otitis media vary by centre; collaborative research in this area is advised.

AbstractMammalian haemosporidian parasites are classified in ten genera, including Plasmodium, Hepatocystis and Nycteria. A high diversity of haemosporidian parasites has been described from bats, but our understanding of their prevalence, distribution and use of hosts remain fragmented. The haemosporidian parasites of bats in Cameroon have been largely understudied, but here, bats, sampled from different habitat types of the Central Region of Cameroon, were investigated for haemosporidian infections with a combination of microscopic and molecular phylogenetic analysis. An overall prevalence of 18.1% of haemosporidian infections was detected in a total of 155 investigated bats belonging to 14 bat species. For the first time Hepatocystis and Nycteria parasites were detected in bats from Cameroon and molecularly characterized. Hepatocystis infections were exclusively identified in the epauletted fruit bat host species Epomophorus pusillus with a high prevalence of 65.5%, whereas Nycteria infections could be detected in several hosts, namely: Doryrhina cyclops (60.0%), Rhinolophus landeri (20.0%) and one Nycteris grandis. This study unveils evidence that habitat types may play a role in transmission of Hepatocystis parasites on a local scale and it adds important information on the distribution and host specificity of the neglected haemosporidian genus Nycteria.
Frozen data? Polar research and fieldwork in a pandemic era
Authors: Duveau Sophie 
Published: September 2021

AbstractDrawing on an ethnographic survey in Svalbard before and during the coronavirus outbreak, this commentary reflects on the multiple dimensions of fieldwork highlighted by the pandemic. Firstly, the cancellation of many field campaigns has revealed the decisive role of personnel inhabiting scientific bases in the maintenance of scientific activities in Svalbard. Automatic and remote-controlled instruments are autonomous only in appearance as the crucial phases of data acquisition often call for human presence. Secondly, airborne remote sensing can be perceived as a response to fill data gaps. Although embedded in a long history, the use of remote sensed data has taken on a new meaning in the context of the pandemic. Finally, the fact that several researchers endeavour to go to the field whatever the travel conditions underlines a certain need of being in Svalbard as well as limitations of science performed remotely.
Social and occupational recovery in early psychosis: a systematic review and meta-analysis of psychosocial interventions

Published: September 2021

AbstractBackgroundPsychosis, even in its early stages, ranks highly among the causes of disability worldwide, resulting in an increased focus on improved recovery of social and occupational functioning. This study aimed to provide an estimate of the effectiveness of psychosocial interventions for improving functioning in early psychosis. We also sought evidence of superiority between intervention approaches.MethodsAn electronic search was conducted using PubMed and PsycINFO to identify original articles reporting on trials of psychosocial interventions in early-stage psychosis, published up to December 2020 and is reported following PRISMA guidelines. Data were extracted on validated measures of functioning from included studies and pooled standardised mean difference (SMD) was estimated.ResultsIn total, 31 studies involving 2811 participants were included, focusing on: cognitive behavioural therapy for psychosis (CBTp), family-based therapy, supported employment, cognitive remediation training (CRT) and multi-component psychosocial interventions. Across interventions, improved function was observed (SMD = 0.239; 95% confidence interval 0.115–0.364, p < 0.001). Effect sizes varied by intervention type, stage of illness, length and duration of treatment and outcome measure used. In particular, interventions based on CRT significantly outperformed symptom-focused CBT interventions, while multi-component interventions were associated with largest gains.ConclusionsPsychosocial interventions, particularly when provided as part of a multi-component intervention model and delivered in community-based settings are associated with significant improvements in social and occupational function. This review underscores the value of sensitively tracking and targeting psychosocial function as part of the standard provided by early intervention services.
Gradience in subject–verb number agreement: Can bilinguals tune in?
Authors: Jessen Anna , Schwarz Lara , Felser Claudia 
Published: September 2021

AbstractThis study investigates native German speakers’ and bilingual Turkish/German speakers’ sensitivity to constraints on verbal agreement with pseudo-partitive subjects such as eine Packung Tabletten (“a pack of pills”). Although number agreement with the first noun phrase (headed by a container noun) is considered to be the norm, agreement with the second (containee) noun phrase is also possible. We combined scalar acceptability ratings with a stochastic constraint-based grammatical framework to model the relative strength of the constraints that determine speakers’ agreement preferences and subsequently tested whether these models could correctly predict speakers’ verb choices in a production task. For both participant groups, number match between the container noun phrase and the verb was the strongest determinant of both acceptability and production choices. The relative ranking of the constraints that we identified was the same for both groups, and the lack of age-of-acquisition effects suggests that constraints on variable subject–verb agreement, and their relative strength, are acquirable by both early and later learners of German. Group differences were seen in the absolute constraint weightings, however, with the bilinguals’ agreement preferences being more strongly influenced by number match with the containee phrase, indicating a comparatively greater reliance on surface-level cues to agreement (such as noun proximity) among the bilingual group.

Published: September 2021

AbstractThis paper presents a modularized autonomous pipeline inspection robot called MRINSPECT VII+, which we recently developed. MRINSPECT VII+ is aimed at inspect in-service urban gas pipelines with a diameter of 200 mm. The robot consists of five basic modules: driving, sensing, joint, and battery modules. For nondestructive testing (NDT), an NDT module can be added to the system. The driving module uses a multiaxial differential gear mechanism to provide traction forces to the robot. The sensor module recognizes the pipeline element using position-sensitive detector (PSD) sensors and a CCD camera. The control module contains a computing unit and manages the robot’s autonomous navigation. The battery module supplies power to the system. Each module is connected via backdrivable active joint modules, which provide flexibility while moving inside narrow pipelines. Additionally, the wireless communication module helps the system communicate with the ground station. We tested MRINSPECT VII+ in real pipeline environments and validated its feasibility successfully.
Study of grasp-energy based optimal distribution of contact forces on a humanoid robotic hand during object grasp
Authors: Mukherjee Sourajit , Mahapatra Abhijit , Kumar Amit , Chatterjee Avik 
Published: September 2021

AbstractA novel grasp optimization algorithm for minimizing the net energy utilized by a five-fingered humanoid robotic hand with twenty degrees of freedom for securing a precise grasp is presented in this study. The algorithm utilizes a compliant contact model with a nonlinear spring and damper system to compute the performance measure, called ‘Grasp Energy’. The measure, subject to constraints, has been minimized to obtain locally optimal cartesian trajectories for securing a grasp. A case study is taken to compare the analytical (applying the optimization algorithm) and the simulated data in MSC.Adams$^{^{\circledR}}$, to prove the efficacy of the proposed formulation.
A dilemma for lexical and Archimedean views in population axiology
Authors: Thornley Elliott 
Published: September 2021

AbstractLexical views in population axiology can avoid the Repugnant Conclusion without violating Transitivity or Separability. However, they imply a dilemma: either some good life is better than any number of slightly worse lives, or else the ‘at least as good as’ relation on populations is radically incomplete. In this paper, I argue that Archimedean views face an analogous dilemma. I thus conclude that the lexical dilemma gives us little reason to prefer Archimedean views. Even if we give up on lexicality, problems of the same kind remain.
EPILOGUE

Published: September 2021

AbstractIn this commentary, we summarize the findings of the seven included studies that examined implicit language aptitude from various perspectives and highlight issues to be resolved in the validation of this new construct in second language research. We start by providing an overview of the contributions of the studies. We then identify the lack of convergent validity of the measures of implicit aptitude reported in the included studies and problematize the equally varied nature of the measurement of implicit knowledge—the outcome variable of aptitude research—and related concepts. In particular, by drawing on empirical evidence and theoretical claims, we attempt to clarify the relationships between implicit and explicit knowledge, implicit and explicit learning, and implicit and explicit instruction. Next, we draw attention to the interactions reported by the included studies between aptitude and outcome measures and between aptitude and instruction type, emphasizing the value and importance of interactional research. We conclude by making recommendations for future research.
Common pulmonary vein atresia

Published: September 2021

AbstractA 4-hour-old infant with profound cyanosis on an alprostadil infusion was urgently transferred to Rady Children’s Hospital with suspected CHD. Upon arrival, urgent echocardiography was performed but could not confirm the presence of discrete pulmonary veins or pulmonary venous drainage. Given the difficulty in delineating the anatomy, a cardiac CT scan was performed and demonstrated a nearly atretic common pulmonary vein with multiple small collaterals that drained to systemic veins. Due to the high risk of mortality associated with operative repair, the decision was made to proceed with compassionate withdrawal of care. The described anatomy of common pulmonary vein atresia remains rare, and to our knowledge, fewer than 40 cases have been reported in the literature. Albeit rare, common pulmonary vein atresia should be considered in the differential diagnosis of a severely cyanotic neonate.
Paediatric dilated cardiomyopathy with and without endocardial fibroelastosis – a pathological analysis of 89 explants
Authors: Reyes Jeanette A. , Dipchand Anne I. , Chiasson David A. 
Published: September 2021

AbstractHeart failure due to dilated cardiomyopathy is a major indication for paediatric cardiac transplantation. Endocardial fibroelastosis is a recognised pathological finding of unknown prognostic significance in paediatric dilated cardiomyopathy. To evaluate the nature of the association between left ventricular endocardial fibroelastosis and paediatric dilated cardiomyopathy, we reviewed surgical pathology reports of dilated cardiomyopathy explants (1986–2016) in order to characterise the pathological findings and to compare and contrast their frequency among four age groups: less than 1 year; 1–5 years; 6–10 years; and greater than 11 years. The 89 explants (47 males and 42 females) were all characterised by increased weight and left ventricular chamber dilatation without increased wall thickness. Ninety-five per cent of the specimens in the two youngest subsets had left ventricular endocardial fibroelastosis. Compared to the oldest age group, recipients aged 1–5 years had a 6-fold increase and those younger than 1 year a 19-fold increase in the odds of observing left ventricular endocardial fibroelastosis. Explants with and without endocardial fibroelastosis were otherwise phenotypically similar. In paediatric dilated cardiomyopathy endocardial fibroelastosis is a very common pathological finding, especially in infants and young children. We propose that the descriptive, clinico-pathological designation “Dilated Cardiomyopathy with Endocardial Fibroelastosis” should be adopted to facilitate future investigation into the potential prognostic/therapeutic significance of left ventricular endocardial fibroelastosis.

AbstractObjectives:We investigated the impact of culturally relevant social, educational, and language factors on cognitive test performance among Spanish speakers living near the US–Mexico border.Methods:Participants included 254 healthy native Spanish speakers from the Neuropsychological Norms for the US–Mexico Border Region in Spanish (NP-NUMBRS) project (Age: M = 37.3, SD = 10.4; Education: M = 10.7, SD = 4.3; 59% Female). A comprehensive neuropsychological battery was administered in Spanish. Individual test scaled scores and T-scores (based on region-specific norms adjusted for age, education, and sex) were averaged to create Global Mean Scaled and T-scores. Measures of culturally relevant factors included a self-reported indicator of educational quality/access (proportion of education in Spanish-speaking country, quality of school/classroom setting, stopped attending school to work), childhood socioeconomic environment (parental education, proportion of time living in Spanish-speaking country, childhood socioeconomic and health status, access to basic resources, work as a child), and Spanish/English language use and fluency.Results:Several culturally relevant variables were significantly associated with unadjusted Global Scaled Scores in univariable analyses. When using demographically adjusted T-scores, fewer culturally relevant characteristics were significant. In multivariable analyses, being bilingual (p = .04) and working as a child for one’s own benefit compared to not working as a child (p = .006) were significantly associated with higher Global Mean T-score, accounting for 9% of variance.Conclusions:Demographically adjusted normative data provide a useful tool for the identification of brain dysfunction, as these account for much of the variance of sociocultural factors on cognitive test performance. Yet, certain culturally relevant variables still contributed to cognitive test performance above and beyond basic demographics, warranting further investigation.
Confronting the Foreigner: Common Policies of Rashid al-Din and Liu Bingzhong on Mongol Rule in Iran and China
Authors: HATEF-NAIEMI ATRI 
Published: September 2021

AbstractThis article discusses the career of three historical figures who had a position of authority in the courts of the Ilkhans and the Great Khans of the Mongol Empire in China: Rashid al-Din Tabib (d. 1318), the Persian statesman and historian; Liu Bingzhong (d. 1274), Qubilai Khan's (r. 1260-94) Chinese counsellor; and Bolad Aqa (d. 1313), the famed Mongol tribesman. This study raises the question of whether Rashid al-Din's policies, when he was in office as the vizier of Ghazan Khan (r. 1295-1304), were modelled in some respects on the approach of the Chinese nobles—Liu in particular—to the Mongols during the early stages of the Mongol rule over China. In addition, taking into account Bolad's noticeable presence in the courts of the Mongols in Ilkhanid Iran and Yuan China, it seeks to shed light on his role as an intermediary and a possible conduit for Chinese political thoughts to reach Rashid al-Din.
Power and Politics of Representation: Picturing Elite Women in Ilkhanid Painting
Authors: CHIDA-RAZVI MEHREEN 
Published: September 2021

AbstractThe first half of the fourteenth century was a discrete period in Ilkhanid Iran during which paintings that pictured elite Mongol women in their true courtly milieu, participating in courtly life and in their contemporary place within societal hierarchies, were produced. It will be argued that a correlation existed between the power wielded by these women in Mongol socio-economic and political spheres and their depictions as formative, important members of the ruling elite; and that the decrease, and ultimate halting, of such representations coincided with changes in their political, cultural and social power. Using Ilkhanid enthronement scenes in the Diez and Istanbul albums to illustrate how visible and prominent the Khātūns were, a fact corroborated by written testimonials of visitors to the Mongol courts, this paper then examines how such images became symbols of legitimacy for later Il-Khans as well as later Persianate rulers in the fourteenth to sixteenth centuries. It will be argued that the image of an enthroned royal Ilkhanid couple carried the weight of political and dynastic legitimacy, and that the inclusion of the Mongol Khātūn was integral to this symbolic importance.

AbstractThe Sikkim-Himalaya represents one of the unique reservoirs of rice genetic resources in India owing to the presence of a large number of landraces adapted to extreme climatic and edaphic conditions. This valuable gene pool is now under threat due to the introduction of high-yielding varieties, wanting suitable genetic intervention for enhancing their productivity, and thus economic viability. Development of lodging resistant, high-yielding varieties tolerant to soil acidity through association mapping aided marker-assisted breeding programmes can help achieve this in a fast and efficient manner. But this requires information on genetic diversity, population structure, etc., of the germplasm collection, which is strikingly lacking. We, therefore, characterized a set of 53 rice landraces from Sikkim to address the above issues. The results revealed moderate diversity, poor divergence and high gene flow in our germplasm collection attesting its utility as an association mapping panel. Further, a total of 115 putative marker-trait associations (P < 0.05, R2 ≥ 10%) were obtained using the general linear model and mixed linear models of which 25 were identical in both. Some of the associated markers were positioned in those regions where Qualitative Trait Loci have been previously identified in rice, providing credence to our results. The resources generated from this study will benefit the rice breeders from this region and elsewhere for targeting the yield and related traits, in addition to conservation efforts by the interested researchers.
