Elasto-capillary circumferential buckling of soft tubes under axial loading: existence and competition with localised beading and periodic axial modes
Authors: Emery Dominic , Fu Yibin 
Published: March 2021

AbstractWe provide an extension to previous analysis of the localised beading instability of soft slender tubes under surface tension and axial stretching. The primary questions pondered here are as follows: under what loading conditions, if any, can bifurcation into circumferential buckling modes occur, and do such solutions dominate localisation and periodic axial modes? Three distinct boundary conditions are considered: in case 1 the tube’s curved surfaces are traction-free and under surface tension, whilst in cases 2 and 3 the inner and outer surfaces (respectively) are fixed to prevent radial displacement and surface tension. A linear bifurcation analysis is conducted to determine numerically the existence of circumferential mode solutions. In case 1 we focus on the tensile stress regime given the preference of slender compressed tubes towards Euler buckling over axisymmetric periodic wrinkling. We show that tubes under several loading paths are highly sensitive to circumferential modes; in contrast, localised and periodic axial modes are absent, suggesting that the circumferential buckling is dominant by default. In case 2, circumferential mode solutions are associated with negative surface tension values and thus are physically implausible. Circumferential buckling solutions are shown to exist in case 3 for tensile and compressive axial loads, and we demonstrate for multiple loading scenarios their dominance over localisation and periodic axial modes within specific parameter regimes.
Money Laundering, Political Corruption and Asset Recovery in the Spanish Criminal Code
Authors: González Uriel Daniel 
Published: March 2021

AbstractThis article analyzes the relationship between corruption offenses and money laundering with reference to the Spanish Penal Code. These two criminal categories lack a certain definition, as there is no such univocal concept of “political corruption” and “money laundering.” The reasons for the denaturation of these criminal figures will be addressed. Then, the paper will expose how these criminal figures relate to each other. We argue that a real concurrence between both figures is possible, although it may lead, in certain cases, to double incrimination and its consequent punitive excess. Therefore, we will propose some criteria for a restrictive interpretation of “money laundering” to avoid confusion with other legal figures such as “confiscation.” The paper will end with reference to the Spanish Criminal Code’s regulation on “confiscation” and a brief review of the main critics.

Published: March 2021

AbstractObjectives:Respiratory transmission, especially in mass gatherings, is considered one of the main ways of influenza transmission. The Hajj ceremony, as one of the largest gatherings worldwide, can increase the distribution of influenza infection. Thus, the present study aimed to evaluate the incidence of influenza among Hajj pilgrims.Methods:In this present systematic review and meta-analysis, all English studies published by 2019 were extracted from several databases such as the Web of Science, PubMed, Scopus, Cochrane Library, Science Direct, and Google Scholar. Finally, the data were extracted using a pre-prepared checklist and then analyzed by fixed and random effects model tests in the meta-analysis, Cochran, meta-regression, and Begg’s test.Results:Eighteen studies with a sample size of 62 431 were entered into the meta-analysis process. The overall prevalence of influenza, in addition to the prevalence of types A, B, and C influenza, was estimated at 5.9 (95% CI: 4.3-8.0), 3.6 (95% CI: 2.6-4.9), 2.9 (95% CI: 2.8-3.1), and 0.9% (95% CI: 0.5-1.5), respectively.Conclusions:In general, influenza remains widespread regardless of vaccinating pilgrims and following health protocols. Therefore, it is recommended that comprehensive management and educational approaches be used to reduce the prevalence of influenza and its adverse consequences among the pilgrims.
Systematic review of effectiveness and satisfaction evaluation in child and adolescent mental health services in Ireland
Authors: Leahy D. , McNicholas F. 
Published: March 2021

Objectives:Increasing numbers of youth experience mental illness, and also require and benefit from specialist child and adolescent mental health services (CAMHS). Worldwide, such services are underfunded and under-resourced, and services in Ireland are no different. It is vital that existing services are regularly reviewed for both efficacy and acceptability. Our objective was to review published studies evaluating service user satisfaction with CAMHS in Ireland and CAMHS therapeutic efficacy.Methods:MEDLINE, PsycINFO and CINAHL databases were systematically searched. Studies were included if they reported on service user satisfaction or an evaluation of CAMHS in Ireland.Results:From an initial 125 articles identified, 15 studies meet the inclusion criteria: four reporting on overall CAMHS satisfaction, three on satisfaction where a specific diagnosis was present, while eight evaluated various interventions offered. Whilst most service users perceived services to be satisfactory, important issues relating to accessibility were present. Evidence of efficacy was present for a small number of interventions, but studies were limited by methodological issues.Conclusions:There is a dearth of studies evaluating CAMHS in Ireland. The extant literature suggests a positive experience once accessed, but long waiting times and poor collaboration are seen to limit services users’ experience. More robust methodologically sound studies are urgently required. Given the expected increased demand linked to the current COVID-19 pandemic, coupled with the resultant compromised financial position, it is essential that scant resources are appropriately directed.

AbstractTo evaluate the feasibility of reintroduction as a tool for conservation of the jaguarPanthera onca, we adapted the IUCN soft release protocol to reintroduce two jaguars in the southern Pantanal, Brazil. After being kept at rescue centres for 13 months, the jaguars were moved to a 1-ha enclosure with native vegetation on a 53,000 ha ranch in the Pantanal, where hunting is not allowed and prey is abundant. In the enclosure, the animals were fed with meat, dead animals (roadkill) and then, progressively, live wild prey. After 11 months, the jaguars were fitted with collars equipped with GPS/VHF (recording one location per hour) and accelerometers, and released in the same area. The animals established residence near the enclosure, with home ranges, movement parameters, daily activity patterns and prey consumption similar to that recorded in previous studies. Social interaction and reproduction indicated the reintroduction was successful, and that it can be a tool for the species' survival in areas where the jaguar population is in decline.

Published: March 2021

AbstractTrichuriasis known as whipworm infection caused byTrichuris trichiura, is a highly prevalent soil-transmitted helminthiasis in low- and middle-income countries located in tropical and subtropical areas and affecting approximately 360 million people. Children typically harbour the largest burden ofT. trichiuraand they are usually co-infected with other soil-transmitted helminth (STH), includingAscaris lumbricoidesand hookworm. The consequences of trichuriasis, such as malnutrition and physical and cognitive growth restriction, lead to a massive health burden in endemic regions. Despite the implementation of mass drug administration of anthelminthic treatment to school-age children,T. trichiurainfection remains challenging to control due to the low efficacy of current drugs as well as high rates of post-treatment re-infection. Thus, the development of a vaccine that would induce protective immunity and reduce infection rate or community faecal egg output is essential. Hurdles for human whipworm vaccine development include the lack of suitable vaccine antigen targets and animal models for humanT. trichiurainfection. Instead, rodent whipwormT. murisinfected mouse models serve as a major surrogate for testing immunogenicity and efficacy of vaccine candidates. In this review, we summarize recent advances in animal models forT. trichiuraantigen discovery and testing of vaccine candidates, while providing an overall view of the current status ofT. trichiuravaccine development.
Effects of tDCS during inhibitory control training on performance and PTSD, aggression and anxiety symptoms: a randomized-controlled trial in a military sample

Published: March 2021

AbstractBackgroundPost-traumatic stress disorder (PTSD), anxiety, and impulsive aggression are linked to transdiagnostic neurocognitive deficits. This includes impaired inhibitory control over inappropriate responses. Prior studies showed that inhibitory control can be improved by modulating the right inferior frontal gyrus (IFG) with transcranial direct current stimulation (tDCS) in combination with inhibitory control training. However, its clinical potential remains unclear. We therefore aimed to replicate a tDCS-enhanced inhibitory control training in a clinical sample and test whether this reduces stress-related mental health symptoms.MethodsIn a preregistered double-blind randomized-controlled trial, 100 active-duty military personnel and post-active veterans with PTSD, anxiety, or impulsive aggression symptoms underwent a 5-session intervention where a stop-signal response inhibition training was combined with anodal tDCS over the right IFG for 20 min at 1.25 mA. Inhibitory control was evaluated with the emotional go/no-go task and implicit association test. Stress-related symptoms were assessed by self-report at baseline, post-intervention, and after 3-months and 1-year follow-ups.ResultsActive relative to sham tDCS neither influenced performance during inhibitory control training nor on assessment tasks, and did also not significantly influence self-reported symptoms of PTSD, anxiety, impulsive aggression, or depression at post-assessment or follow-up.ConclusionsOur results do not support the idea that anodal tDCS over the right IFG at 1.25 mA enhances response inhibition training in a clinical sample, or that this tDCS-training combination can reduce stress-related symptoms. Applying different tDCS parameters or combining tDCS with more challenging tasks might provide better conditions to modulate cognitive functioning and stress-related symptoms.
Access to health care among racialised immigrants to Canada in later life: a theoretical and empirical synthesis
Authors: Lin Shen (Lamson) 
Published: March 2021

AbstractEvidence that immigrants tend to be underserved by the health-care system in the hosting country is well documented. While the impacts of im/migration on health-care utilisation patterns have been addressed to some extent in the existing literature, the conventional approach tends to homogenise the experience of racialised and White immigrants, and the intersecting power axes of racialisation, immigration and old age have been largely overlooked. This paper aims to consolidate three macro theories of health/behaviours, including Bronfenbrenner's ecological theory, the World Health Organization's paradigm of social determinants of health and Andersen's Behavioral Model of Health Service Use, to develop and validate an integrated multilevel framework of health-care access tailored for racialised older immigrants. Guided by this framework, a narrative review of 35 Canadian studies was conducted. Findings reveal that racial minority immigrants’ vulnerability in accessing health services are intrinsically linked to a complex interplay between racial-nativity status with numerous markers of power differences. These multilevel parameters range from socio-economic challenges, cross-cultural differences, labour and capital adequacy in the health sector, organisational accessibility and sensitivity, inter-sectoral policies, to societal values and ideology as forms of oppression. This review suggests that, counteracting a prevailing discourse of personal and cultural barriers to care, the multilevel framework is useful to inform upstream structural solutions to address power imbalances and to empower racialised immigrants in later life.
Older workers imagining retirement: the collapse of agency, or freedom at last?
Authors: Grødem Anne Skevik , Kitterød Ragni Hege 
Published: March 2021

AbstractImages of what retirement is and ought to be are changing. Older workers are being encouraged to work for longer, at the same time, older adults increasingly voice expectations of a ‘third age’ of active engagement and new life prospects. In this article, we draw on the literature on older workers’ work patterns and retirement transitions (noting push/pull/stay/stuck/jump factors), and on scholarship on the changing social meaning of old age, most importantly the notions of a ‘third’ and ‘fourth’ age. The analysis is based on qualitative interviews with 28 employees in the private sector in Norway, aged between 55 and 66 years. Based on the interviews, we propose three ideal-typical approaches to the work–retirement transition: ‘the logic of deadline’, ‘the logic of negotiation’ and ‘the logic of averting retirement’. The ideal-types are defined by the degree to which informants assume agency in the workplace, their orientation towards work versus retirement and the degree to which they expect to exercise agency in retirement. We emphasise how retirement decisions are informed by notions of the meaning of ageing, while also embedded in relationships with employers and partners.
In the moment with music: an exploration of the embodied and sensory experiences of people living with dementia during improvised music-making

Published: March 2021

AbstractThe term ‘in the moment’ has received growing interest in the context of music programmes for people living with dementia, with music therapists, family carers, health-care professionals and people living with dementia themselves reporting the value of framing musical experiences in the ‘here and now’. Although this term is being used more frequently within the literature, there has yet to be a formal examination of such ‘in the moment’ musical experiences and how they might benefit a person living with dementia. We used a multiple-case study approach to develop a thematic framework of ‘in the moment’ musical experiences within the context of a music-making programme for people living with dementia. The research followed six people living with dementia and four family carers, and used video-observation and video-elicitation interviews to capture and analyse ‘in the moment’ experiences. Four thematic observations were developed which captured ‘in the moment’ musical experiences: Sharing a life story through music, Musical agency ‘in the moment’, Feeling connected ‘in the moment’ and Musical ripples into everyday life. These findings showcase the creativity and musical abilities of people living with dementia whilst affirming music as a medium to connect people living with dementia with their own life story, other people and the environments in which music-making takes place.
Phonological neighborhood measures and multisyllabic word acquisition in children
Authors: RAJARAM Melissa 
Published: March 2021

Abstract
Multisyllabic words constitute a large portion of children's vocabulary. However, the relationship between phonological neighborhood density and English multisyllabic word learning is poorly understood. We examine this link in three, four and six year old children using a corpus-based approach. While we were able to replicate the well-accepted positive association between CVC word acquisition and neighborhood density, no similar relationship was found for multisyllabic words, despite testing multiple novel neighborhood measures. This finding raises the intriguing possibility that phonological organization of the mental lexicon may play a fundamentally different role in the acquisition of more complex words.
Sphere tangencies, line incidences and Lie’s line-sphere correspondence
Authors: ZAHL JOSHUA 
Published: March 2021

AbstractTwo spheres with centers p and q and signed radii r and s are said to be in contact if |p–q|2=(r–s)2. Using Lie’s line-sphere correspondence, we show that if F is a field in which –1 is not a square, then there is an isomorphism between the set of spheres in F3 and the set of lines in a suitably constructed Heisenberg group that is embedded in (F[i])3; under this isomorphism, contact between spheres translates to incidences between lines.In the past decade there has been significant progress in understanding the incidence geometry of lines in three space. The contact-incidence isomorphism allows us to translate statements about the incidence geometry of lines into statements about the contact geometry of spheres. This leads to new bounds for Erdős’ repeated distances problem in F3, and improved bounds for the number of point-sphere incidences in three dimensions. These new bounds are sharp for certain ranges of parameters.

Modular waveguide filter platform for educational and prototyping purposes
Authors: Miek Daniel , Bruhn Daniel , Braasch Kennet , Kamrath Fynn , Boe Patrick , Höft Michael 
Published: March 2021

AbstractIn this paper, a modular waveguide filter platform suitable for educational and prototyping purposes is presented. The waveguide filter platform is dimensioned to work in the F-band (4.9–7.05 GHz). The design of the platform is discussed and versatile application possibilities are shown in many examples. The platform can be used to realize generalized Chebyshev filters with or without cross-couplings by exploiting TE101 and TE102 mode cavities. Transmission zeros can be introduced by the utilization of wires or aperture couplings. Filter topologies based on the extracted pole technique can be examined as well. Small changes in the set-up also allow the realization of a gap waveguide filter, a diplexer set-up as well as filters with frequency-dependent coupling apertures. Most required components can either be purchased cheaply or be manufactured with a three-dimensional printer.
Determining Threshold Instrumental Resolutions for Resolving the Velocity‐Space Signature of Ion Landau Damping

Published: March 2021

AbstractUnraveling the physics of the entire turbulent cascade of energy in space and astrophysical plasmas from the injection of energy at large scales to the dissipation of that energy into plasma heat at small scales, represents an overarching, open question in heliophysics and astrophysics. The fast cadence and high phase‐space resolution of particle velocity distribution measurements on modern spacecraft missions, such as the recently launched Parker Solar Probe, presents exciting new opportunities for identifying turbulent dissipation mechanisms using in situ measurements of the particle velocity distributions and electromagnetic fields. Here we demonstrate how to use data from kinetic numerical simulations of plasma turbulence to create synthetic spacecraft data; this data set can then be used to determine instrumental requirements to identify specific particle energization mechanisms. Using such synthetic data, downsampled to the velocity phase‐space resolution available from the plasma instruments on several past and present missions, we compute the resulting velocity‐space signature of ion Landau damping using the recently developed Field‐Particle Correlation (FPC) technique. We find that only recent missions have sufficiently fine phase‐space resolution to resolve the characteristic resonant features of the ion Landau damping signature. Coupled with numerical determinations of the velocity‐space signatures of different proposed particle energization mechanisms, this strategy enables the specification of instrumental capabilities required to achieve science goals on the topic of plasma heating and particle acceleration in turbulent heliospheric plasmas.
Nodal Structure of Toroidal Standing Alfvén Waves and Its Implication for Field Line Mass Density Distribution
Authors: Takahashi Kazue , Denton Richard E. 
Published: March 2021

AbstractWe have conducted a statistical study of toroidal mode standing Alfvén waves detected by the Van Allen Probes spacecraft in the dayside inner magnetosphere, with an emphasis on the nodal structure of the fundamental through fifth harmonics. We developed a technique to accurately assign harmonic mode numbers to peaks in the power spectra of the electric (Eν) and magnetic (Bϕ) field components of toroidal waves and then determine the spectral intensities of Eν and Bϕ and the coherence and cross‐phase between these field components for each harmonic. The magnetic latitude (MLAT) dependence of these quantities was statistically examined to determine the location of the nodes. In addition to the equatorial nodes located close to the equator (MLAT = 0), we identified several nodes away from the equator within the MLAT range from −20° to +20°. We found that the Eν‐Bϕ cross‐phase is very close to ±90° except near the nodes, indicating that the fixed‐end approximation is appropriate in modeling dayside toroidal waves. Noting that the node latitudes depend on the distribution of the mass density (ρ) along the background magnetic field, we inferred the distribution from the nodes observed at L = 4–6. If we adopt a model field line mass density (ρ) distribution of the form ρ ∝ (1/r)α, where r is geocentric distance to the field line and α is a free parameter, the statistically determined node latitudes indicate that α∼1.5 is appropriate for both the plasmasphere and the plasmatrough.
