description: Modern wind turbine blades implement carbon fiber-reinforced polymer (CFRP) planks in their load carrying structures, i. e., the spar caps. These CFRP planks are pre-manufactured in a pultrusion process and are stacked into the blade structure. The pultrusion process ensures a high quality with respect to fiber alignment, fiber volume fraction, and low manufacturing defects. All these metrics can be manufactured with a high reproducibility leading to outstanding mechanical properties. CFRP structures can be damaged during operation, e.g., due to voids, undulations, defects, dielectric breakdowns, or flashovers because of a lightning strike [1]. Conventional repair techniques by infusion of dry fiber patches cannot achieve the properties of the original CFRP planks. Therefore, pre-cured and chamfered CFRP plank patches are bonded into the recess. In case innermost CFRP planks are damaged in the inboard blade region, a repair from the blade's inside is required, which requires grinding off the damaged CFRP planks and cutting away a window from the shear web. An up-tower repair is generally preferred over a down-tower repair at site or in the workshop when considering the longer downtime and higher efforts for logistics as well as mounting. In an up-tower repair situation the temporarily weakened structure needs to withstand extreme wind situations, in particular offshore. To this end, this research investigates the feasibility of an up-tower repair concept by means of (i) simulations and (ii) practical considerations. Therefore, a detailed finite element model of a commercial rotor blade, which was designed for a 7MW offshore turbine, was subjected to a maintenance design load situation. The blade loads were determined by aeroelastic simulations. The weakened blade structure was investigated towards permissible strains and buckling for conducting the repair.

description: The critical velocity vc for the onset of turbulent drag of small spheres oscillating in superfluid 4He is frequency dependent (omega/2pi from 100 Hz to 700 Hz) and is described by vc = 2.6sqrt(kappa*omega), where kappa is the circulation quantum. A qualitative analysis based on a recent theory of the onset of superfluid turbulence gives vc = sqrt(8*kappa*omega/beta), where beta is of order 1 and depends on the coefficients of mutual friction. This agrees well with the data and implies that vc is a universal critical velocity that is independent of geometry, size, and surface properties of the oscillating body. This is confirmed by comparing our data on spheres with vc obtained with other oscillating structures by other groups. Numerical simulations indicate somewhat larger critical velocity, above which a rapid increase in vortex length is observed.

Subjects: classificationCode: 4602
subject: Artificial intelligence

description: This study examines the determinants affecting office manager’s implementation of artificial intelligence (AI) in Bahrain, with an emphasis on generational viewpoints. The study investigates the attitudes, challenges, and preferences of four generational cohorts: Baby Boomers, Generation X, Millennials, and Generation Z regarding AI adoption in professional environments. The study employs the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Technology Threat Avoidance Theory (TTAT) as theoretical frameworks to identify significant generational differences in AI adoption, encompassing trust issues, job security concerns, and training needs. A qualitative methodology was utilized using semi-structured interviews to obtain comprehensive insights. Research indicates that Baby Boomers display skepticism towards AI, primarily due to concerns about job displacement, but Millennials and Gen Z demonstrate greater enthusiasm, appreciating AI for its efficiency and creativity. Recommendations encompass the implementation of customized training programs, the promotion of intergenerational collaboration, the resolution of ethical issues, and the assurance of transparent AI practices. This study offers practical ways for organizations in Bahrain to successfully address generational disparities, fostering inclusive and sustainable AI implementation.

description: Intermetallic compounds containing f-electron elements display a wealth of superconducting phases, that are prime candidates for unconventional pairing with complex order parameter symmetries. For instance, superconductivity has been found at the border of magnetic order as well as deep within ferro- and antiferromagnetically ordered states, suggesting that magnetism may promote rather than destroy superconductivity. Superconductivity near valence transitions, or in the vicinity of magneto-polar order are candidates for new superconductive pairing interactions such as fluctuations of the conduction electron density or the crystal electric field, respectively. The experimental status of the study of the superconducting phases of f-electron compounds is reviewed.

description: Single molecule force spectroscopy methods can be used to generate folding trajectories of biopolymers from arbitrary regions of the folding landscape. We illustrate the complexity of the folding kinetics and generic aspects of the collapse of RNA and proteins upon force quench, using simulations of an RNA hairpin and theory based on the de Gennes model for homopolymer collapse. The folding time, $τ_F$, depends asymmetrically on $δf_S = f_S - f_m$ and $δf_Q = f_m - f_Q$ where $f_S$ ($f_Q$) is the stretch (quench) force, and $f_m$ is the transition mid-force of the RNA hairpin. In accord with experiments, the relaxation kinetics of the molecular extension, $R(t)$, occurs in three stages: a rapid initial decrease in the extension is followed by a plateau, and finally an abrupt reduction in $R(t)$ that occurs as the native state is approached. The duration of the plateau increases as $λ=τ_Q/τ_F$ decreases (where $τ_Q$ is the time in which the force is reduced from $f_S$ to $f_Q$). Variations in the mechanisms of force quench relaxation as $λ$ is altered are reflected in the experimentally measurable time-dependent entropy, which is computed directly from the folding trajectories. An analytical solution of the de Gennes model under tension reproduces the multistage stage kinetics in $R(t)$. The prediction that the initial stages of collapse should also be a generic feature of polymers is validated by simulation of the kinetics of toroid (globule) formation in semiflexible (flexible) homopolymers in poor solvents upon quenching the force from a fully stretched state. Our findings give a unified explanation for multiple disparate experimental observations of protein folding.

description: Previous research suggests that parental attachment is stable throughout emerging adulthood. However, the relationships between the mutual attachments in the dyads of emerging adults and their parents are still unclear. Our study examines the stability and change in dyadic attachment. We asked 574 emerging adults and 463 parents at four occasions over 1 year about their mutual attachments. We used a latent state-trait model with autoregressive effects to estimate the time consistency of the attachments. Attachment was very stable, and earlier measurement occasions could explain more than 60% of the reliable variance. Changes of attachment over time showed an accumulation of situational effects for emerging adults but not for their parents. We estimated the correlations of the mutual attachments over time using a novel multi-rater latent state-trait model with autoregressive effects. This model showed that the mutual attachments of parents and emerging adults were moderately to highly correlated. Our model allows to separate the stable attachment from the changing attachment. The correlations between the mutual attachments were higher for the stable elements of attachment than for the changing elements of attachment. Emerging adults and their parents share a stable mutual attachment, but they do not share the changes in their respective attachments.
Non-local Realistic Theories and the Scope of the Bell Theorem
Creators: name: Laudisa, Federico
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: According to a widespread view, the Bell theorem establishes the untenability of so-called 'local realism'. On the basis of this view, recent proposals by Leggett, Zeilinger and others have been developed according to which it can be proved that even some non-local realistic theories have to be ruled out. As a consequence, within this view the Bell theorem allows one to establish that no reasonable form of realism, be it local or non-local, can be made compatible with the (experimentally tested) predictions of quantum mechanics. In the present paper it is argued that the Bell theorem has demonstrably nothing to do with the 'realism' as defined by these authors and that, as a consequence, their conclusions about the foundational significance of the Bell theorem are unjustified.

description: Gija is an endangered Australian Aboriginal language spoken in the east Kimberley region of northern Western Australia. It is no longer acquired as a first language, nor spoken fluently by younger generations of Gija people, who instead largely speak Kimberley Kriol (an English-based lingua franca) with some Gija vocabulary. Due to widespread concern about the vitality of their language, many members of the community are actively engaged in language revitalisation efforts. Although academic publications are scarce, the linguists who have worked with the Gija community since the 1980s have produced language-learning materials and records of ethnobiological knowledge, oral history, and stories told through painting. Numerous community-oriented language publications aimed at maintenance of the language and culture have also been produced. A video corpus of face-to-face Gija conversations is currently being developed to support community-led initiatives for language documentation and revitalisation.

They live in a dozen villages in the southernmost part of the Guéra region in Chad. The Kulaawe are traditionally agriculturalists: they grow mainly sorghum and millet, as well as maize, groundnut, and beans. The inhabitants of the village of Tilé Nougar are additionally historically blacksmiths, and used to extract, melt, smelt, and forge iron. The Kulaawe are all Muslims today, although their conversion is relatively recent, and aspects of their pre-Islamic practices still survive. Many Kulaawe also live in towns, mostly Sarh and N’Djamena, where the language is usually not passed on to the younger generations. In general, the language and the traditions it carries are under threat due to rapid economic and demographic change in the country.

description: Nobiin is a Nile-Nubian language originally spoken along the Nile River in Egypt and Sudan. Rilly & de Voogt (2012) estimate that the Nobiin community today consists of about 545,000 members. Of those, about 500,000 are in Egypt and Sudan, and the rest live as refugees in Europe, the United States (US), and the Arabian Gulf (Rilly & de Voogt, 2012), due to the coerced displacement of much of the Nobiin community in the 1960s. Nobiin is currently considered to be an endangered language. Several members of the Nobiin communities in the US and elsewhere are currently engaged in revitalization programs, including literacy projects for native Nobiin-speaking adults and children of the Nobiin community.

The Evolution of form and function across taxonomic scales of passerines
Creators: name: Reaney, Ashley
Publisher: name: Imperial College London
Year: 2020

description: Adaptive radiations, the process by which organisms diversify both taxonomically and ecologically, have been attributed to underline the majority of living biodiversity. This type of evolutionary radiation typically transpires following the exploitation of vacant niche space though is not restricted to insular communities as numerous large clades likely diversified in much the same way. There is considerable variation in morphological and ecological diversity both within and between clades at all taxonomic scales. Several near-complete phylogenetic trees and datasets were used to investigate clade disparity in abstract space, trait evolution and the associations between morphology, ecology and diversification rates. These were combined to assess whether imbalances in speciation rates occur among taxa possessing particularly extreme morphologies in beak and body traits. New approaches capturing disparity metrics were used to quantitively analyse the hypervolumes of diverse families and smaller subclades within multidimensional space. These metrics were then employed to assess whether passerine families possess greater disparity in either their beak or body morphospaces. Thraupidae are an incredibly diverse passerine family with its various subclades exhibiting contrasting levels of taxonomic and morphological diversity. Analysis of these two evolutionary aspects revealed speciation rates are often decoupled from trait disparity among the various tanager subclades. Finally, the extreme disparity in form among the nested adaptive radiations within Thraupidae and other passerine families were explored to assess their contrasting trajectories with other endemic taxa to understand how such discrepancy in diversity was achieved and the factors that likely generated it.

description: Tropical cyclones (TCs) are one of the most destructive natural hazards that pose a serious threat to society, particularly to those in the coastal regions. In this work, we study the temporal evolution of the regional weather conditions in relation to the occurrence of TCs using climate networks. Climate networks encode the interactions among climate variables at different locations on the Earth’s surface, and in particular, time-evolving climate networks have been successfully applied to study different climate phenomena at comparably long time scales, such as the El Niño Southern Oscillation, different monsoon systems, or the climatic impacts of volcanic eruptions. Here, we develop and apply a complex network approach suitable for the investigation of the relatively short-lived TCs. We show that our proposed methodology has the potential to identify TCs and their tracks from mean sea level pressure (MSLP) data. We use the ERA5 reanalysis MSLP data to construct successive networks of overlapping, short-length time windows for the regions under consideration, where we focus on the north Indian Ocean and the tropical north Atlantic Ocean. We compare the spatial features of various topological properties of the network, and the spatial scales involved, in the absence and presence of a cyclone. We find that network measures such as degree and clustering exhibit significant signatures of TCs and have striking similarities with their tracks. The study of the network topology over time scales relevant to TCs allows us to obtain crucial insights into the effects of TCs on the spatial connectivity structure of sea-level pressure fields.

description: We compute the cosmological constant in a scale invariant scalar field theory. The gravitational action is also suitably modified to respect scale invariance. Due to scale invariance the theory does not admit a cosmological constant term. The scale invariance is broken by a recently introduced mechanism called cosmological symmetry breaking. This leads to a nonzero cosmological constant. We compute the one loop corrections to the cosmological constant and show that it is finite.

Ibatan of Babuyan Claro (Philippines) – Language Contexts
Creators: name: Gallego, Maria Kristina
Publisher: name: Language Documentation and Description
Year: 2020

description: Babuyan Claro is a small island in northern Philippines, home to a dynamic multilingual community of speakers proficient in at least three languages, namely Ibatan, the local language, Ilokano, the regional lingua franca, and Filipino, the national language. Ibatan, the smallest of the three, has emerged out of an intense and complex contact setting in Babuyan Claro characterized by a kind of egalitarian multilingualism, but its less privileged position vis-à-vis Ilokano and Filipino at present has led to changing patterns of multilingualism across generations, driven by interacting social, political, and cultural changes. Currently, language choices and uses among the first-language and second-language speakers of Ibatan reflect how speakers form networks of interaction across the island. That is, speakers strongly tied to particular networks reflect greater affinity towards Ibatan, whereas those tied to other networks show stronger affinity towards Ilokano. The multilingual landscape of Babuyan Claro is one that clearly demonstrates not only change, but also fragility, where the effect of extra-linguistic pressures on the language ecology of the island has become more and more pronounced as the community has become further integrated into the modern nation state.

description: We investigate the three-dimensional structure of the pulsar magnetosphere through time-dependent numerical simulations of a magnetic dipole that is set in rotation. We developed our own Eulerian finite difference time domain numerical solver of force-free electrodynamics and implemented the technique of non-reflecting and absorbing outer boundaries. This allows us to run our simulations for many stellar rotations, and thus claim with confidence that we have reached a steady state. A quasi-stationary corotating pattern is established, in agreement with previous numerical solutions. We discuss the prospects of our code for future high-resolution investigations of dissipation, particle acceleration, and temporal variability.

description: In the paper we discuss possible approaches to the problem of the rigorous derivation of quantum kinetic equations from underlying many-particle dynamics. For the description of a many-particle evolution we construct solutions of the Cauchy problems of the BBGKY hierarchy and the dual BBGKY hierarchy in suitable Banach spaces. In the framework of the conventional approach to the description of kinetic evolution the mean-field asymptotics of the quantum BBGKY hierarchy solution is constructed. We develop also alternative approaches. One method is based on the construction of the solution asymptotics of the initial-value problem of the quantum dual BBGKY hierarchy. One more approach is based on the generalized quantum kinetic equation that is a consequence of the equivalence of the Cauchy problems of such evolution equation and the BBGKY hierarchy with initial data determined by the one-particle density operator.

Karl Pearson's meta-analysis revisited

description: This paper revisits a meta-analysis method proposed by Pearson [Biometrika 26 (1934) 425--442] and first used by David [Biometrika 26 (1934) 1--11]. It was thought to be inadmissible for over fifty years, dating back to a paper of Birnbaum [J. Amer. Statist. Assoc. 49 (1954) 559--574]. It turns out that the method Birnbaum analyzed is not the one that Pearson proposed. We show that Pearson's proposal is admissible. Because it is admissible, it has better power than the standard test of Fisher [Statistical Methods for Research Workers (1932) Oliver and Boyd] at some alternatives, and worse power at others. Pearson's method has the advantage when all or most of the nonzero parameters share the same sign. Pearson's test has proved useful in a genomic setting, screening for age-related genes. This paper also presents an FFT-based method for getting hard upper and lower bounds on the CDF of a sum of nonnegative random variables.

description: Our understanding of the evolutionary process has gone a long way since the publication, 150 years ago, of "On the origin of species" by Charles R. Darwin. The XXth Century witnessed great efforts to embrace replication, mutation, and selection within the framework of a formal theory, able eventually to predict the dynamics and fate of evolving populations. However, a large body of empirical evidence collected over the last decades strongly suggests that some of the assumptions of those classical models necessitate a deep revision. The viability of organisms is not dependent on a unique and optimal genotype. The discovery of huge sets of genotypes (or neutral networks) yielding the same phenotype --in the last term the same organism--, reveals that, most likely, very different functional solutions can be found, accessed and fixed in a population through a low-cost exploration of the space of genomes. The 'evolution behind the curtain' may be the answer to some of the current puzzles that evolutionary theory faces, like the fast speciation process that is observed in the fossil record after very long stasis periods.

title: Structural and Functional characterization of the LDP3 (VHZ) Protein Tyrosine Phosphatase
Creators: name: Kuznetsov, Vyacheslav I.
Publisher: name: Utah State University
Year: 2013

description: Protein phosphorylation is as an important regulatory mechanism that controls a large number of physiologically important cellular processes. Proteins are phosphorylated on aliphatic (serine and threonine) as well aromatic (histidine and tyrosine) residues predominantly located on sterically accessible loops. Phosphorylation affects three- dimensional structures of proteins resulting in conformational changes which activate or deactivate enzymatic functions. Because of the ability of protein phosphorylation to modulate a multitude of diverse cellular processes, it became an appealing and promising target for drug therapy.Attachment of phosphate is accomplished by kinases, whereas the removal of the phosphoryl group is performed by protein phosphatases. Traditionally, protein kinases have been studied more intensely than protein phosphatases due to the earlier belief that they confer fine regulation to protein phosphorylation, whereas protein phosphatases act to nonspecifically remove phosphate groups. In recent years the protein phosphatases were subjected to thorough analysis to reveal a number of diverse properties which formed the basis for phosphatase classification. The family of protein tyrosine phosphatses (PTPs) represents the largest group of protein phosphatases known today.We focused our study on the 150 amino acids VHZ phosphatase, which was originally classified as a dual-specificity enzyme which can dephosphorylate aliphatic (phospho serine, phospho threonine) and aromatic (phospho tyrosine) residues. We solved a crystal structure of VHZ refined to 1.1 Å resolution and performed an extensive structural, biological and kinetic analysis which revealed that this enzyme is not a dual specificity phosphatase. Activity screening with 360 biologically relevant peptides indicated strict phospho-tyrosine specificity and provided important information about its physiological substrates. Mechanistic studies using steady-state and pre-steady state kinetics, as well as inhibition studies and kinetic isotope effects (KIE) explain the significantly reduced catalytic parameters of VHZ, and contribute to our understanding of the PTP catalytic mechanism in general.
Direct Bounds on the Tau Neutrino Mass from LEP
Creators: name: L. Passalacqua
Publisher: name: INFN Open Access Repository
Year: 1996

description: A review of direct bounds on the mass of the tau neutrino obtained at the LEP collider is presented. In addition to published results it includes preliminary results presented at recent conferences and new results presented at the 1996 Tau Workshop. The different techniques and decay modes employed by the ALEPH, DELPHI and OPAL collaborations are compared. The impact of the theoretical modelling of tau decays is also discussed. The most stringent 95% CL limit on the tau neutrino mass is now obtained by a preliminary ALEPH analysis which combines the results from τ->5π^±(π^0)v_r and τ->3π^±v_r decays. This bound constraints the mass of the tau neutrino below 18.2 MeV/c2.
Cooling and squeezing the fluctuations of a nanomechanical beam by indirect quantum feedback control

description: We study cooling and squeezing the fluctuations of a nanomechanical beam using quantum feedback control. In our model, the nanomechanical beam is coupled to a transmission line resonator via a superconducting quantum interference device (SQUID). The leakage of the electromagnetic field from the transmission line resonator is measured using homodyne detection. This measured signal is then used to design a quantum-feedback-control signal to drive the electromagnetic field in the transmission line resonator. Although the control is imposed on the transmission line resonator, this quantum-feedback-control signal indirectly affects the thermal motion of the nanomechanical beam via the inductive beam-resonator coupling, making it possible to cool and squeeze the fluctuations of the beam, allowing it to approach the standard quantum limit.

description: Western Rengma (Terüpvunyu /tərYɸuɲu/) is an undocumented Angami-Pochuri language from the Tibeto-Burman language family. Preliminary fieldwork was conducted during April 2018 in Karbi Anglong district, Assam, India to document the language and understand the language attitudes of the speakers, in addition to identifying domains of language use. The dominant language in the district is colloquial Assamese, an Eastern Indo-Aryan language used as a lingua franca by Rengma speakers, blended with Nagamese, a creole from the neighbouring state of Nagaland. Western Rengma bears a resemblance to Southern Rengma, while Northern Rengma is totally distinct. Research is still required to confirm the identity of Western and Central Rengma and to understand the sociolinguistic situation of the language.

title: A Multiday Record-Assisted Fruit, Vegetable, and Snack Questionnaire to Assess Intake Among Fourth and fifth Grade Students
Creators: name: Lambert, Anne B.
Publisher: name: Utah State University

description: Assessing FV intake among young children is difficult and can be a time- consuming, resource-intensive, and burdensome. The aim of this study was to create a simple, self-assessment tool to estimate and detect changes in FV consumption among fourth and fifth graders. Such a tool would ease the complications and resources of other diet assessment options that are used to measure FV consumption when implementing school-based nutrition programs.The questionnaire provided a moderately valid estimate of lunchtime FV consumption, but it was inconsistent at detecting small, yet important increases in FV consumption between time points. The ability of the questionnaire to measure total FV consumption was also tested and found to be poor. In addition, having the students record what they ate on a food tracker during meals did not improve performance on the questionnaire.The tool examined in this study could provide a reasonable estimate of average lunchtime FV consumption among fourth and fifth grade children, but could not be used to detect sensitive changes in consumption during a FV intervention study. While it is difficult for children to recall dietary information, it beneficial to continue to explore the development of a self-report questionnaire that can accurately assess total FV intake in children.
