AbstractFontan surgery is a life-saving procedure for newborns with complex cardiac malformations, but it originates complications in different organs. The liver is also affected, with development of fibrosis and sometimes cirrhosis and hepatocellular carcinoma. There is no general agreement on how to follow-up these children for the development of liver disease. To understand the current practice on liver follow-up, we invited members of the European Society of Paediatric Radiology (ESPR) to fill out an online questionnaire. The survey comprised seven questions about when and how liver follow-up is performed on Fontan patients. While we found some agreement on the use of US as screening tool, and of MRI for nodule characterization, the discrepancies on timing and the lack of a shared protocol make it currently impossible to compare data among centers.
Poisson voting games under proportional rule
Authors: De Sinopoli Francesco , Meroni Claudia 
Published: October 2021

AbstractWe analyze strategic voting under proportional rule and two parties, embedding the basic spatial model into the Poisson framework of population uncertainty. We prove that there exists a unique Nash equilibrium. We show that it is characterized by a cutpoint in the policy space that is always located between the average of the two parties’ positions and the median of the distribution of voters’ types. We also show that, as the expected number of voters goes to infinity, the equilibrium converges to that of the case with deterministic population size.
Transient behavior of imperfect bi-directional functionally graded sandwich plates under moving loads

Published: October 2021

AbstractAn investigation of dynamic behaviors of a sandwich plate containing an imperfect two dimensional functionally graded (2D-FG) core surrounded by two faces on a two-parameter elastic foundation and subjected to a moving load is carried out in this paper. The present sandwich solid is composed of a porous 2D-FG core covered by two homogenous layers. It is assumed that the middle layer has micro voids dispersed uniformly and unevenly through the layer thickness. The fundamental equations are governed within the framework of first-order-shear deformation theory by utilizing Hamilton’s principle, von-Karman geometrical nonlinearity and the principal of mixtures. Newmark direct integration procedure is implemented to transform the dynamic equations into a static form and then the kinetic dynamic relaxation numerical technique in conjunction with the finite difference discretization method are employed to solve the nonlinear partial differential governing equations. Finally, the effects of porosity fraction and scattering patterns, boundary constrains, the variation of materials’ grading indexes and elastic foundation constants on the transient performances of the plate are studied in detail.
Discrete Carleman estimates and three balls inequalities
Authors: Fernández-Bertolin Aingeru , Roncal Luz , Rüland Angkana , Stan Diana 
Published: October 2021

AbstractWe prove logarithmic convexity estimates and three balls inequalities for discrete magnetic Schrödinger operators. These quantitatively connect the discrete setting in which the unique continuation property fails and the continuum setting in which the unique continuation property is known to hold under suitable regularity assumptions. As a key auxiliary result which might be of independent interest we present a Carleman estimate for these discrete operators.
Renaming of Hallervorden–Spatz disease: the second man behind the name of the disease
Authors: Voges Luca , Kupsch Andreas 
Published: October 2021

AbstractHallervorden–Spatz disease (HSD) has been recently renamed to pantothenate kinase-associated neurodegeneration (PKAN) and neurodegeneration with brain iron accumulation (NBIA), mainly due to the unethical behavior of Julius Hallervorden in the National Socialist (NS) euthanasia program of the Nazi Third Reich. The role of the second name giver in the NS euthanasia program is less clear. Hugo Spatz was the director of the Kaiser Wilhelm Institute for Brain Research in Berlin-Buch during World War II (WWII), renamed to Max Planck Institute after 1945. After the war, he headed the Max Planck Institute for Brain Research in Frankfurt am Main. The present study investigates the potential involvement of Hugo Spatz in the NS euthanasia program. In the present study, we compared a list of euthanasia victims from the German Federal Archive Berlin (30.146 cases published after the reunification of Germany, BArch R179) with the files of the collection of specimens from 1940 until 1945 of Hugo Spatz as listed in the Archive of the Max Planck Society Berlin-Dahlem (n = 305). Furthermore, the old term HSD and the new terms PKAN and NBIA were systematically searched in PubMed from 1946, through January 2019 to evaluate the renaming process from HSD to PKAN/NBIA. Following Hugo Spatz’s death in 1969 growing evidence indicated that he may have taken part in the NS euthanasia program. This study identifies 4 euthanized victims in the patient files of Hugo Spatz from 1940 to 1945, suggesting involvement of Hugo Spatz in the NS euthanasia program. This further strengthens the argument that the former HSD should be exclusively referred to as PKAN or NBIA.
Metaplasticity in the human swallowing system: clinical implications for dysphagia rehabilitation
Authors: Cheng Ivy , Hamdy Shaheen 
Published: October 2021

Abstract
Dysphagia is a common and devastating complication following brain damage. Over the last 2 decades, dysphagia treatments have shifted from compensatory to rehabilitative strategies that facilitate neuroplasticity, which is the reorganization of neural networks that is essential for functional recovery. Moreover, there is growing interest in the application of cortical and peripheral neurostimulation to promote such neuroplasticity. Despite some preliminary positive findings, the variability in responsiveness toward these treatments remains substantial. The purpose of this review is to summarize findings on the effects of neurostimulation in promoting neuroplasticity for dysphagia rehabilitation and highlight the need to develop more effective treatment strategies. We then discuss the role of metaplasticity, a homeostatic mechanism of the brain to regulate plasticity changes, in helping to drive neurorehabilitation. Finally, a hypothesis on how metaplasticity could be applied in dysphagia rehabilitation to enhance treatment outcomes is proposed.
Raising the level: orangutans solve the floating peanut task without visual feedback
Authors: Sebastián-Enesco Carla , Amezcua-Valmala Nerea , Colmenares Fernando , Mendes Natacha , Call Josep 
Published: October 2021

AbstractChimpanzees and orangutans are able to generate innovative behaviors to solve complicated physical problems. For example, when presented with an out-of-reach peanut at the bottom of a vertical tube (floating peanut task—FPT), some of them spontaneously spit water into the tube until the peanut floats to the top. Yet, it is unclear whether this innovative solution results from repeating those actions that bring the peanut incrementally closer to the top or from anticipating the solution before acting. In the current study, we addressed this question by presenting three naïve orangutans with an opaque version of the FPT that prevented them from obtaining visual information about the effect of their actions on the position of the peanut. One of the subjects solved the opaque FPT in the very first trial: he collected water from the faucet and poured it into the opaque tube repeatedly until the hitherto non-visible peanut reached the top. This provides evidence for the first time that orangutans can potentially solve the FPT without relying on sensorimotor learning, but to some extent by mentally representing the problem.
Comorbidity Between Internalising and Externalising Disorders Among Adolescents: Symptom Connectivity Features and Psychosocial Outcome
Authors: Essau Cecilia A. , de la Torre-Luque Alejandro 
Published: October 2021

AbstractInternalising disorders are highly prevalent conditions in adolescence and tend to co-occur with externalising disorders. The present study used a symptom network approach to examine the interplay between symptoms of internalising disorders among adolescents with comorbid internalising and externalising disorders. Data comes from the National Comorbidity Survey—Adolescent Supplement, a nationally representative survey of adolescents aged 13 to 18 years. The most central symptoms across the disorders in the network were poor self-esteem and worry. The comorbidity between anxiety and depression increases the probability of having comorbid externalising disorders. Adolescents with both internalising and externalising disorders had the highest rate of health service utilisation. Comorbidity group, lifestyle factors, deficits in cognitive and academic competence and coping skills were significant covariates of the mental health outcomes. Understanding comorbidity profile of internalising and externalising disorders and central symptoms that bridge these disorders could have important clinical implications.
Technologies in the education of children and teenagers with autism: evaluation and classification of apps by work areas

Published: October 2021

AbstractMobile apps represent a resource with great potential for encouraging the development of many skills, given the high number of apps available and the quick access to them. Many professionals and families include these resources in the education and therapy of children with autism. For a group with such particular needs, a review of the apps is great importance, since, due to their characteristics, the apps must provide content, design and pedagogical aspects that fit those needs. Through a previously validated system of indicators, 155 free apps on Google Play were evaluated, using “autism” in English and in Spanish. We determined which work area each app developed, as well as which were the most multifaceted. Having evaluated the recorded data, we calculated frequencies, percentages and reliability, as well as parametric contrast and correlation statistics. We found that the focus of most apps was on executive functions, language and entertainment, with a minority devoted to the emotional sphere or time management. However, 98.06% of the apps worked on several areas, which makes them more functional but with the downside of not being specialized. Most apps were placed in the “recommendable” level but with margin for improvement in increasing their functionality.
The Metaphysics of Decoherence
Authors: Vassallo Antonio , Romano Davide 
Published: October 2021

AbstractThe paper investigates the type of realism that best suits the framework of decoherence taken at face value without postulating a plurality of worlds, or additional hidden variables, or non-unitary dynamical mechanisms. It is argued that this reading of decoherence leads to a type of perspectival realism which is extremely radical, especially when cosmological decoherence is considered.
Linking Up: The Role of Institutions and Farmers in Forage Seed Exchange Networks of Southeast Asia
Authors: Leyte James D. , Delaquis Erik , Van Dung Pham , Douxchamps Sabine 
Published: October 2021

AbstractIn Southeast Asia, access to improved forages remains a challenge for smallholder farmers and limits livestock production. We compared seed exchange networks supporting two contrasting livestock production systems to identify bottlenecks in seed availability and determine the influences of the market, institutions, and cultural context of seed exchange, using interview-based methods for ‘seed tracing’ and network analysis. Government agencies were the primary sources of high-quality genetic materials, with secondary diffusion in the Philippines dairy case being dominated by key individuals in active cooperatives. In the Vietnamese beef-oriented production context, farmer to farmer dissemination was more substantial. In both cases, formal actors dominated where botanical seed was exchanged, while farmers frequently exchanged vegetatively propagated materials among themselves. To improve access to forage seed in these contexts, government agencies and development actors should coordinate quality seed production upstream while supporting the creation of appropriate training, structures, and incentives for seed exchange network improvement downstream.
The Persistence of Political Power: A Communist ‘Party Village’ in Kerala and the Paradox of Egalitarian Hierarchies
Authors: Kaul Nitasha , Kannangara Nisar 
Published: October 2021

AbstractThis article combines political analysis with ethnographic fieldwork to theorise Communist party’s construction of political allegiance and their persistence of power in the democratic context at a local village level in the state of Kerala in India. We provide an inaugural scholarly conceptualisation of an empirical phenomenon, known in Kerala popular parlance as ‘party gramam’ or the ‘party village’, as the focus of analysis. As we explain, a ‘party village’ is an administrative unit where a particular political party dominates not simply electorally but in all lived experience. We posit that the concept of ‘party village’ is of specific value in our understanding of various forms of current (Communist) politics. The original ascendancy of communism in the village (as in many regions of Kerala) during the twentieth century was due to its progressive ideological challenge to feudal structures of class and caste oppression. However, in democratic post-independence India, the overwhelming dominance of Communist Party in the 'party village' presents the paradox of a party with an egalitarian ideology having adapted to a persistent Hindu caste hierarchy. After situating our work within the conceptual problematisations of political party competition, and in conversation with wider communist studies literature, we provide a background to the politics of Kerala and explain the unique phenomenon of ‘party villages’ in Kerala. We then provide an insight into the social and economic structures of one such village, explaining the salience of these structures in relation to political allegiances. Next, we illustrate the paradox of continued caste hierarchies in a Communist Party village, and the multiple ways in which Hindu religion and caste structures are important to performing individual identity in social settings. We dissect the various means through which the grassroots Communist Party apparatus in the village maintains its dominance by adapting itself to regressive caste hierarchies for political profit at the same time as laying claim to having challenged them. In our concluding section, we place our village observations in the longer frame of historical north Kerala village politics, noting the changes over time and offering theoretical perspectives upon them. In this sense, through a mix of empirical observation with historical context and theorisation, we highlight the importance and the implications of unconventional democratic dynamics more generally.
“It’s Like Stealing What Should be Theirs.” An Exploration of the Experiences and Perspectives of Parents and Educational Practitioners on Hebrew–English Bilingualism for Jewish Autistic Children
Authors: Sher David Ariel , Gibson Jenny L. , Browne Wendy V. 
Published: October 2021

AbstractParents of autistic children are routinely advised to raise them monolingually, despite potential negative effects of monolingualism and no evidence of harm from bilingualism. There is, however, limited research on this topic. This study explored experiences and perspectives of educational practitioners (‘practitioners’) and parents of Hebrew–English bilingual autistic children on bilingualism and monolingualism. Using interpretative phenomenological analysis, we explored the experiences of 22 parents and 31 practitioners using both oral and written interviews. The analysis revealed that religious continuity is a crucial factor in bilingual decision-making. Unexpectedly, both practitioners and parents felt that having to adopt a monolingual approach was unjust, in line with conceptions of forced monolingualism. This article recommends awareness training on community languages and research in other communities.
Long-Term Immune Recovery After Hematopoietic Stem Cell Transplantation for ADA Deficiency: a Single-Center Experience

Abstract
Unconditioned hematopoietic stem cell transplantation (HSCT) is the recommended treatment for patients with adenosine deaminase (ADA)-deficient severe combined immunodeficiency with an HLA-matched sibling donor (MSD) or family donor (MFD). Improved overall survival (OS) has been reported compared to the use of unrelated donors, and previous studies have demonstrated that adequate cellular and humoral immune recovery can be achieved even in the absence of conditioning. Detailed insight of the long-term outcome is still limited. We aim to address this by studying a large single-center cohort of 28 adenosine deaminase-deficient patients who underwent a total of 31 HSCT procedures, of which more than half were unconditioned. We report an OS of 85.7% and event-free survival of 71% for the entire cohort, with no statistically significant differences after procedures using related or unrelated HLA-matched donors. We find that donor engraftment in the myeloid compartment is significantly diminished in unconditioned procedures, which typically use a MSD or MFD. This is associated with poor metabolic correction and more frequent failure to discontinue immunoglobulin replacement therapy. Approximately one in four patients receiving an unconditioned procedure required a second procedure, whereas the use of reduced intensity conditioning (RIC) prior to allogeneic transplantation improves the long-term outcome by achieving better myeloid engraftment, humoral immune recovery, and metabolic correction. Further longitudinal studies are needed to optimize future management and guidelines, but our findings support a potential role for the routine use of RIC in most ADA-deficient patients receiving an HLA-identical hematopoietic stem cell transplant, even when a MSD or MFD is available.
Parallel-machine scheduling of jobs with mixed job-, machine- and position-dependent processing times
Authors: Przybylski Bartłomiej 
Published: October 2021

AbstractWe consider a number of parallel-machine scheduling problems in which jobs have variable processing times. The actual processing time of each job is described by an arbitrary positive function of the position it holds on a machine. However, the function itself may additionally depend on the job or a machine this job was assigned to. Our aim is to find a schedule that minimizes the objectives of maximum completion time or the total completion time. We present a full set of polynomial solutions for the cases of jobs with no precedence constraints. We also show that the case of single-chained jobs may be not easier in general, but some polynomial results can be obtained, too.
Invariant Algebraic Surfaces of Polynomial Vector Fields in Dimension Three
Authors: Kruff Niclas , Llibre Jaume , Pantazi Chara , Walcher Sebastian 
Published: October 2021

AbstractWe discuss criteria for the nonexistence, existence and computation of invariant algebraic surfaces for three-dimensional complex polynomial vector fields, thus transferring a classical problem of Poincaré from dimension two to dimension three. Such surfaces are zero sets of certain polynomials which we call semi-invariants of the vector fields. The main part of the work deals with finding degree bounds for irreducible semi-invariants of a given polynomial vector field that satisfies certain properties for its stationary points at infinity. As a related topic, we investigate existence criteria and properties for algebraic Jacobi multipliers. Some results are stated and proved for polynomial vector fields in arbitrary dimension and their invariant hypersurfaces. In dimension three we obtain detailed results on possible degree bounds. Moreover by an explicit construction we show for quadratic vector fields that the conditions involving the stationary points at infinity are generic but they do not a priori preclude the existence of invariant algebraic surfaces. In an appendix we prove a result on invariant lines of homogeneous polynomial vector fields.
Do Online Gambling Products Require Traditional Therapy for Gambling Disorder to Change? Evidence from Focus Group Interviews with Mental Health Professionals Treating Online Gamblers
Authors: Lopez-Gonzalez Hibai , Jimenez-Murcia Susana , Rius-Buitrago Alicia , Griffiths Mark D. 
Published: October 2021

AbstractOnline gambling has significantly altered the situational and structural characteristics of gambling products, to the extent that online gamblers might be substantially different from traditional offline gamblers. A growing body of literature has identified the evolving features of online gambling and the individuals who engage in it. However, beyond understanding the individual characteristics of this subgroup, relatively less effort has been made to examine whether existing cognitive-behavioural therapy (CBT) approaches are still entirely relevant for online problem gamblers, or whether changes are needed to adapt according to gambling mode of access. To understand what kind of challenges online gambling poses to mental health professionals dealing with disordered gamblers, four focus groups comprising 28 Spanish participants were carried out. All the treatment providers had ongoing experience with online gamblers undergoing treatment, and included clinical psychologists, mental health social workers, and a medical doctor. The data were examined using thematic analysis. The analysis identified five main themes that characterised online gamblers: (1) being of younger age, (2) lack of conflicts at home and at work/educational centre, rarely presenting violent or aggressive behaviour, (3) gambling disorder only being identified by overdue debt, (4) co-occurring conditions with technology-related abuse rather than other substance-related addictions, and (5) skill-based gambling. The study highlights mental health workers’ perceived insecurities about how to best treat online gamblers, and discusses the specific characteristics that CBT for gambling disorder might need to incorporate to adjust for this particular group of gamblers.
