Studies on cyclic behavior of tripod suction bucket foundation system supporting offshore wind turbine using centrifuge model test
Authors: Jeong Yeong‐Hoon , Ko Kil‐Wan , Kim Dong‐Soo , Kim Jae‐Hyun 
Published: November 2020

AbstractTo be competitive in offshore wind energy production, safe and economical foundation design is essential. In recent years, tripod suction bucket foundations have been considered as an alternative to conventional foundations owing to their unique features suitable for offshore construction environments, economic installation, and high overturning resistance. However, it is difficult to accurately predict the behavior of tripod foundation because the load acting on the tripod is complex in HVM (i.e., horizontal, vertical, and moment loads) and the response varies depending on the size and direction of the load. Moreover, it is harder to analyze because the effects of cyclic loads must be considered in an offshore environment. This study, therefore, has investigated the behavior of the tripod suction bucket foundation under cyclic loadings. To analyze the complex responses of the tripod foundation in detail, the overall behavior of the tripod foundation system was observed based on the compression–pullout behavior of a single bucket. Moment–rotation responses, the cyclic stiffness, and permanent displacements of the tripod foundation are evaluated by analyzing the vertical behavior of the single‐bucket foundations as well as the rotational behavior of the tripod foundation. A number of centrifuge model tests were carried out with different loading conditions (i.e., loading amplitudes and directions). It was confirmed that the cyclic behavior of the tripod bucket foundation is significantly affected by loading amplitudes and directions. Furthermore, this study emphasized the importance of considering load characteristics when designing the tripod foundation.

Abstract
We present the production cross section for a lepton-neutrino pair at the Large Hadron Collider computed at next-to-next-to-next-to-leading order (N3LO) in QCD perturbation theory. We compute the partonic coefficient functions of a virtual W± boson at this order. We then use these analytic functions to study the progression of the perturbative series in different observables. In particular, we investigate the impact of the newly obtained corrections on the inclusive production cross section of W± bosons, as well as on the ratios of the production cross sections for W+, W− and/or a virtual photon. Finally, we present N3LO predictions for the charge asymmetry at the LHC.
Mapping class groups of highly connected $$(4k+2)$$-manifolds
Authors: Krannich Manuel 
Published: November 2020

AbstractWe compute the mapping class group of the manifolds$$\sharp ^g(S^{2k+1}\times S^{2k+1})$$♯g(S2k+1×S2k+1)for$$k>0$$k>0in terms of the automorphism group of the middle homology and the group of homotopy$$(4k+3)$$(4k+3)-spheres. We furthermore identify its Torelli subgroup, determine the abelianisations, and relate our results to the group of homotopy equivalences of these manifolds.
Antibacterial activity of Zn-loaded Cuban zeolite against Helicobacter pylori in comparison to its Na-loaded and unmodified counterparts

Published: November 2020

AbstractHelicobacter pylori can be found in the stomach of about half of the humans, and a large population can be associated with serious diseases. To survive in the stomach H. pylori increases the pH locally by producing ammonia which binds to H+ becoming ammonium. This work investigated the effects on the in-vitro growth of H. pylori of a natural cation-exchanger mainly composed (≈70%) of clinoptilolite and mordenite. The zeolitized material from Cuba was evaluated in its original form (M), as well as in its Na- (M-Na) and Zn-exchanged (M-Zn) counterparts. In the preliminary agar cup diffusion test, H. pylori revealed susceptibility only to M-Zn, with a direct relationship between concentration and width of inhibition halo. Further experiments evidenced that bacterium replication increases when ammonium is supplied to the growth medium and decreases when zeolites subtract NH4+ via ion exchange. Due to the multi-cationic population of its zeolites M was not effective enough in removing ammonium and, in the Minimum Inhibitory Concentration (MIC) test, allowed bacterial growth even at a concentration of 50 mg/mL. Inhibition was achieved with M-Na because it contained sodium zeolites capable of maximizing NH4+ subtraction, although the MIC was high (30 mg/mL). M-Zn evidenced a more effective inhibitory capacity, with a MIC of 4 mg/mL. Zinc has antimicrobial properties and H. pylori growth was affected by Zn2+ released from clinoptilolite and mordenite. These zeolites, being more selective towards NH4+ than Zn2+, can also subtract ammonium to the bacterium, thus enhancing the efficacy of M-Zn.
Life Cycle Assessment and Judgement
Authors: Nathan Christopher , Coles Stuart 
Published: November 2020

AbstractIt has become a standard for researchers carrying out biotechnology projects to do a life cycle assessment (LCA). This is a process for assessing the environmental impact of a technology, product or policy. Doing so is no simple matter, and in the last decades, a rich set of methodologies has developed around LCA. However, the proper methods and meanings of the process remain contested. Preceding the development of the international standard that now governs LCA, there was a lively debate in the academic community about the inclusion of ‘values’ within the process. We revisit this debate and reconsider the way forward for LCA. We set out ways in which those outside of science can provide input into LCAs by informing the value assumptions at stake. At the same time, we will emphasize that the role of those within the scientific community need not (and sometimes, will inevitably not) involve value-free inquiry. We carry out this exploration through a case study of a particular technology project that sought ways to produce industrial and consumer products from algal oils.
Condition Assessment Techniques for Aged Fixed-Type Offshore Platforms Considering Decommissioning: a Historical Review
Authors: Wahab Mohamed Mubarak Abdul , Kurian V. John , Liew Mohd Shahir , Kim Do Kyun 
Published: November 2020

AbstractIn this study, the technical papers on structural condition assessment of aged fixed-type offshore platforms reported over the past few decades are presented. Other ancillary related works are also discussed. Large numbers of researches are available in the area of requalification for life extension of offshore jacket platforms. Many of these studies involve reassessment of existing platforms by means of conducting pushover analysis, a static nonlinear collapse analysis method to evaluate the structure nonlinear behaviour and capacity beyond the elastic limit. From here, the failure mechanism and inherent reserve strength/capacity of the overall truss structure are determined. This method of doing reassessment is described clearly in the industry-adopted codes and standards such the API, ISO, PTS and NORSOK codes. This may help understand the structural behaviour of aged fixed offshore jacket structures for maintenance or decommissioning.

Published: November 2020

AbstractPurposeSmall intestinal neuroendocrine tumours (siNETs) with a Ki-67 proliferation index between 3 and 20% belong to WHO grade 2. Response to treatment may be monitored by blood chromogranin A (CgA) and urine 5-hydroxyindoleacetic acid (5HIAA). The aim of this retrospective study was to investigate the prognostic value of baseline CgA and 5HIAA and of the early biochemical response to treatment, and to compare different cut-off values used in the literature.MethodsA retrospective cohort study of 184 patients with siNET Grade 2 treated with somatostatin analogues (SSA), interferon-alpha (IFN) or peptide receptor radionuclide therapy (PRRT).ResultsBaseline CgA was a statistically significant prognostic marker for both cancer-specific survival (CSS) and progression-free survival (PFS). A cut-off of 5 × ULN (upper limit of normal) was best discriminative in most cases, but 2 × ULN discriminated better for SSA. Baseline 5HIAA was a prognostic marker for CSS in treatment with IFN and PRRT, but not for single SSA. Early changes of CgA and 5HIAA correlated well with CSS (HR 3.18, 95% CI 1.82–5.56 and HR 1.47, 95% CI 1.16–1.86) and PFS (HR 3.08, 95% CI 1.86–5.10 and HR 1.37, 95% CI 1.11–1.68) for SSA, but not for PRRT.ConclusionsBaseline CgA and to a lesser extent 5HIAA are associated with CSS irrespective of treatment used, and with PFS after PRRT, and 5 × ULN provides best discrimination in many, but not all, cases. Early reductions of CgA and 5HIAA are prognostic for treatment with SSA, but not PRRT.

AbstractChronic Obstructive Pulmonary Disease (COPD) is a long-term progressive inflammatory lung disease causing chronic breathlessness and many hospital admissions. It affects up to 1.2 million people in the UK. To help people with COPD self-manage their condition we developed, in partnership with healthcare users, a digital mobile phone app called COPD.Pal®. We report the first user feedback of COPD.Pal®, applying the Technology Acceptance Model (TAM) theoretical framework.11 participants engaged with a click dummy version of COPD.Pal® before being asked questions relating to their experiences. A deductive, semantic, reflexive thematic analysis was conducted to analyse their individual and collective experiences. The study was registered at Clinical Trials.gov (NCT04142957).Two overarching themes resulted: Ease of Use and Perceived Usefulness. Within the former, participants discussed how they wanted flexibility and choice in how they engaged with the app; including how often they used it. Additionally, they discussed how the app layout should make it straightforward to use, whilst unanimously agreeing that COPD.Pal® provided this. Within Perceived Usefulness, participants discussed how they wanted the information they entered into the app to be useful, in addition to the app providing resources regarding COPD. Lastly, there was disagreement regarding preferences for further app development.We found that COPD.Pal® was usable and acceptable by people with COPD and TAM provided a useful theoretical framework for both structuring discussions with users and analysing their comments.
Decision-making skills of high-performance youth soccer players
Authors: Murr Dennis , Larkin Paul , Höner Oliver 
Published: November 2020

Abstract
Objectives
This study aimed to develop a valid video-based diagnostic instrument that assesses decision-making with a sport-specific motor response.

Methods
A total of 86 German youth academy players (16.7 ± 0.9 years) viewed game situations projected on a large video screen and were required to make a decision by dribbling and passing to one of three targets (representing different decision options). The test included 48 clips separated into two categories: build-up (bu) and offensive decisions (off). Criterion-related validity was tested based on age (i.e., U16, U17, and U19), playing status (i.e., minutes played in official matches of the current season) and in a prospective approach relating to future youth national team status (i.e., selected or nonselected). Finally, it was investigated whether decision-making competence was influenced by playing position (i.e., defenders vs. midfielders vs. forwards).

Results
Instrumental reliability demonstrated satisfactory values for SCbu (r = 0.72), and lower for SCoff (r = 0.56). Results showed the diagnostic instrument is suitable for discriminating between playing status (SCbu: Φ = 0.22, p < 0.01; SCoff: Φ = 0.14, p < 0.05) and between younger (U16) and older players (U17 > U16 in SCbu: Φ = 0.24 and SCoff: Φ = 0.39, p < 0.01; U19 > U16 in SCbu: Φ = 0.41 and SCoff: Φ = 0.46, p < 0.01); however, there was no difference between U17 and U19 players. Furthermore, the predictive value of the test indicates that future youth national team players make better decisions with respect to the build-up category (SCbu: Φ = 0.20; p < 0.05), whereas playing position did not significantly influence decision-making competence.

Conclusion
Results indicate the video-based decision-making diagnostic instrument can discriminate decision-making competence within a high-performance youth group. The outcomes associated with national youth team participation demonstrate the predictive value of the diagnostic instrument. This study provides initial evidence to suggest a new video-based diagnostic instrument with a soccer-specific motor response can be used within a talent identification process to assist with assessment of decision-making performance.

Published: November 2020

ZusammenfassungDie Gestaltung eines interessefördernden (Chemie‑)Unterrichts ist Anspruch von Unterricht und bildungswissenschaftlicher sowie fachdidaktischer Forschung. Gemäß des 4‑Phasen-Modells der Interessenentwicklung ist es sinnvoll, auf die Förderung des labileren situationalen Interesses zu fokussieren, da dies den Ausgangspunkt zur Entwicklung eines stabileren individuellen Interesses darstellen kann. Faktoren, sogenannte Trigger, die in verschiedensten Studien als potenziell interessefördernd identifiziert worden sind, sind vielfältig. Trotz einer langen Forschungstradition ist bis heute unklar, welche Auswirkungen der Einsatz von kombinierten Triggern im Unterricht auf das situationale Interesse hat und inwiefern Lernercharakteristika die Perzeption von Triggern beeinflusst. Daher wurde eine explorative Beobachtungsstudie im Chemieunterricht in neun gymnasialen Klassen der achten Jahrgangsstufe durchgeführt. Mittels einer qualitativen Inhaltsanalyse konnten unterschiedliche Trigger extrahiert und verschiedenen Unterrichtsphasen zugeordnet werden. Der Einsatz von Alltagskontexten wurde bspw. am häufigsten in Einstiegsphasen gefunden. Weiterhin wurde der Einfluss des mittleren situationalen Interesses der Lernenden auf die Wahrnehmung von Triggern untersucht: Experimente werden von niedriginteressierten Lernenden generell als interessant wahrgenommen, während die Wahrnehmung der Hochinteressierten differenzierter bezüglich u. a. der Einbettung in den Unterricht ist. Auf Basis der Ergebnisse werden erste Hypothesen zu möglichen Wirkmechanismen aufgestellt.
Development and Validation of an Implicit Relational Assessment Procedure (IRAP) to Measure Implicit Dysfunctional Beliefs about Caregiving in Dementia Family Caregivers
Authors: Cabrera Isabel , Márquez-González María , Kishita Naoko , Vara-García Carlos , Losada Andrés 
Published: November 2020

AbstractCaregivers of people with dementia who endorse dysfunctional beliefs about caregiving are at high risk of experiencing higher levels of distress. These dysfunctional beliefs are presented in the form of rules, verbal statements that specify what responsibilities one should expect in order to be a “good caregiver,” and are characterized as rigid, unrealistic, or highly demanding. Previous studies relied exclusively on self-report measures when assessing such dysfunctional beliefs about caregiving. The objectives of this study were: 1) to develop and validate an Implicit Relational Assessment Procedure (IRAP) to measure implicit dysfunctional beliefs about caregiving (CARE-IRAP), and 2) considering the relatively high age of the sample, to analyze the adaptation of the IRAP for older adults, comparing the IRAP performance between older adult caregivers and middle-aged caregivers. Participants were 123 dementia family caregivers with a mean age of 62.24 ± 12.89. Adaptations were made to the IRAP by adjusting the accuracy and response time criteria. The sample was split into middle-aged caregivers (below 60 years) and older adult caregivers (60 or older). The CARE-IRAP scores presented significant positive correlations with explicit measures of dysfunctional beliefs about caregiving and experiential avoidance in caregiving. A similar pattern of results was observed across the two age groups. The results revealed that caregivers endorse implicit dysfunctional beliefs about caregiving and offer preliminary support for the use of the IRAP as a valid measure of implicit caregiving beliefs. This exploratory study is the first to adapt the IRAP criteria to older adults, and future studies should further explore criteria suitable for this population.
Voting behavior is unaffected by subtle linguistic cues: evidence from a psychologically authentic replication
Authors: GERBER ALAN S. , HUBER GREGORY A. , FANG ALBERT H. 
Published: November 2020

AbstractDo small wording differences in message-based behavioral interventions have outsized effects on behavior? An influential initial study, examining this question in the domain of political behavior using two small-scale field experiments, argues that subtle linguistic cues in voter mobilization messages describing someone as a voter (noun) instead of one who votes (verb) dramatically increases turnout rates by activating a person's social identity as a voter. Two subsequent large-scale replication field experiments challenged this claim, finding no effect even in electorally competitive settings. However, these experiments may not have reproduced the psychological context needed to motivate behavioral change because they did not occur in highly competitive and highly salient electoral contexts. Addressing this major criticism, we conduct a large-scale, preregistered replication field experiment in the 2016 presidential election. We find no evidence that noun wording increases turnout compared to verb wording in this highly salient electoral context, even in competitive states.

AbstractIn this cross-sectional population-based study, women had significantly higher crude incidence rates of both community-associated Clostridioides difficile infection (CA-CDI) and ambulatory antibiotic prescriptions compared to men in South Carolina in 2015. After adjustments for antibiotic prescription rates, there was no difference in the incidence rates of CA-CDI between the genders.
THE LEGITIMACY OF CAPITAL CONTROLS DURING A RETREAT FROM GLOBALISATION
Authors: Mercurio Bryan , Buckley Ross , Fu Erin Jiangyuan 
Published: November 2020

AbstractCapital controls—measures taken to regulate the outflow or inflow of capital—are employed by governments to maintain financial stability and prevent or mitigate the effects of economic crises. For many decades capital controls were out of favour among economists and policymakers. Of late, however, they have become acceptable, if somewhat controversial, tools of financial policy, with the International Monetary Fund stating that ‘in certain circumstances, [capital controls] can be useful to support macroeconomic adjustment and safeguard financial stability’. Yet, little is known about the legality of capital controls under the various international treaties and rules of international organisations. This article introduces capital controls, traces their evolution over time, considers the success of short-term and long-term controls implemented in Chile, Malaysia, Iceland and China, and examines the consistency of selected controls with international rules and obligations. We suggest treaty language will be the critical factor in determining the legality of a particular capital control under a trade or investment agreement.

Published: November 2020

AbstractIn this paper, a novel miniaturized and flexible dual band frequency selective surface (FSS) is presented. This FSS provides effective shielding in X-band and Ku- band, with a frequency response of 9.4 and 16.7 GHz, respectively. The proposed FSS provides 924 MHz bandwidth at X-band and 1.34 GHz bandwidth at Ku-band with an insertion loss of 20 dB. Moreover, the proposed design is polarization-independent and it provides stable frequency response at various angles of incidences for both transverse electric and transverse magnetic modes. More significantly, the proposed FSS analyzed the bandstop response of the selective frequency and also is suitable for conformal applications. A prototype of the proposed FSS is fabricated. The measured results and simulated results are good in agreement.

AbstractA terrestrial gamma‐ray flash (TGF) associated with an Elve was recently reported by the Atmosphere‐Space Interactions Monitor (ASIM) (Neubert et al., 2020,https://doi.org/10.1126/science.aax3872). An extremely low frequency electromagnetic field pulse coinciding with this event was detected by two stations of our World Extremely Low Frequency (ELF) Radiolocation Array (WERA) project from a distance of more than 10,000 km. The recorded signal allowed us to radiolocate the source, determine its polarity, and calculate the charge moment of the associated atmospheric discharge. Our analysis shows that this TGF was associated with a powerful discharge that had a positive polarity and the charge momentp ≈ 125 C·km.

AbstractThe development of the sequencing technologies allowed the generation of huge amounts of molecular data from a single cancer specimen, allowing the clinical oncology to enter the era of the precision medicine. This massive amount of data is highlighting new details on cancer pathogenesis but still relies on tissue biopsies, which are unable to capture the dynamic nature of cancer through its evolution. This assumption led to the exploration of non-tissue sources of tumoral material opening the field of liquid biopsies. Blood, together with body fluids such as urines, or stool, from cancer patients, are analyzed applying the techniques used for the generation of omics data. With blood, this approach would allow to take into account tumor heterogeneity (since the circulating components such as CTCs, ctDNA, or ECVs derive from each cancer clone) in a time dependent manner, resulting in a somehow “real-time” understanding of cancer evolution. Liquid biopsies are beginning nowdays to be applied in many cancer contexts and are at the basis of many clinical trials in oncology.
