description: We present a very general geometrico-dynamical description of physical or more abstract entities, called the 'general tension-reduction' (GTR) model, where not only states, but also measurement-interactions can be represented, and the associated outcome probabilities calculated. Underlying the model is the hypothesis that indeterminism manifests as a consequence of unavoidable fluctuations in the experimental context, in accordance with the 'hidden-measurements interpretation' of quantum mechanics. When the structure of the state space is Hilbertian, and measurements are of the 'universal' kind, i.e., are the result of an average over all possible ways of selecting an outcome, the GTR-model provides the same predictions of the Born rule, and therefore provides a natural completed version of quantum mechanics. However, when the structure of the state space is non-Hilbertian and/or not all possible ways of selecting an outcome are available to be actualized, the predictions of the model generally differ from the quantum ones, especially when sequential measurements are considered. Some paradigmatic examples will be discussed, taken from physics and human cognition. Particular attention will be given to some known psychological effects, like question order effects and response replicability, which we show are able to generate non-Hilbertian statistics. We also suggest a realistic interpretation of the GTR-model, when applied to human cognition and decision, which we think could become the generally adopted interpretative framework in quantum cognition research.

A new species of psychrophilic bdelloid rotifer from North America
Creators: name: DiMattia, Lydia Michelina
Publisher: name: No Publisher Supplied
Year: 2023

description: Rotifers are aquatic invertebrates known for their high tolerance and adaptability when faced with environmental stressors such as drought and extreme temperatures. Here, a bdelloid rotifer was discovered in a shelved beaker stored for ~6 years at 4˚C, originally collected from a field sample on Deception Glacier, WA. DNA sequencing at nuclear and mitochondrial loci followed by phylogenetic analyses revealed three haplotypes that share a close evolutionary relationship with an ice-obligate, Norwegian rotifer lineage. Viability experiments established their growth rate between 4 – 37˚C, survivability after freezing at -20˚C, and pH tolerance between 5.8 – 7.9. A metagenomic analysis of the glacial meltwater sample revealed a highly diverse fungal and bacterial community. Collectively, these data identify a new species of bdelloid rotifer, and the first glacier-obligate Rotifera discovered in North America.

description: En este artículo se analizan las representaciones políticas que circularon a través de la predicación religioso-católica para los años de 1816 a 1822. Esta línea temporal abarca en realidad, dos periodos importantes para entender el papel de la oratoria sagrada como articulador de potestades políticas: el primero que va de 1816 a 1820, los cuales son los años de la reconquista fernandina en la Nueva Granada; y el segundo empieza de 1819 a 1822, periodo en el cual se consolida la independencia. En el primer periodo se estudiará el discurso religioso desde la visión de los predicadores que defienden a la monarquía, y en el segundo periodo se analizará el discurso religioso desde los predicadores que están a favor de la independencia y la república. En ambos casos se verá como la predicación refleja las intenciones políticas de los poderes en disputa, cuya finalidad última es la de legitimarse

description: The Superior Colliculus, a laminar structure involved in the retinotopic mapping of the visual field, plays a cardinal role in the several cortical and subcortical loops of the saccadic system. Although the selection of saccade targets has long been thought to be the sole product of cortical processes, a growing body of evidence hints at the implication of the Superior Colliculus, firstly by the lateral connections between the neurons of its maps, and secondly by its interactions with the midbrain Basal Ganglia, already renowned for their role in decision making. We propose a biomimetic population-coded race model of selection based on a dynamic tecto-basal loop that reproduces the observed ability of the Superior Colliculus to stochastically select between similar stimuli, the accuracy of this selection depending on the discriminability of the target and the distractors. Our model also offers an explanation for the phenomenon of Remote Distractor Effect based on the lateral connectivity within the Basal Ganglia circuitry rather than on lateral inhibitions within the collicular maps. Finally, we propose a role for the intermediate layers of the Superior Colliculus, as stochastic integrators dynamically gated by the selective disinhibition of the Basal Ganglia channels that is consistent with the recorded activity profiles of these neurons.
Molecular mechanism of reversed temperature dependence of ATP synthesis in glacier ice worms
Creators: name: Abdelrahman, Noureen
Publisher: name: No Publisher Supplied
Year: 2023

description: The F0F1 ATP synthase enzyme is highly conserved across species. The F0F1 is a reversible motor, where the counterclockwise rotation of the rotor portion of F0 (known as the c-ring and present in the membrane-embedded F0 domain) produces ATP, and the clockwise rotation induces ATP hydrolysis. In a surprising contrast to temperate organisms, glacier ice worms display elevated ATP levels as temperatures decline. The increased energy expenditure is used as a strategy for survival at cold temperatures, but the mechanism is unknown. More specifically, an ice worm-specific, 18 amino acid extension with regularly spaced histidine residues was previously found to be fused to the carboxy-terminal of the ATP6 subunit generating a proton shuttling domain projecting away from the F0 exit pore. The role of this C-terminal extension in the temperature dependence ATP synthesis in ice worms is undetermined. To investigate the underlying mechanism of elevated ATP levels in glacier ice worms, we sought to understand the effects of temperature on the dynamics of the F0F1 ATP synthase of ice worm, yeast and ice worm without the ATP6 extension. We conducted all-atomistic MD simulations of the F0 domain subunits at different temperatures to evaluate the effect of sequence on temperature dependence. We also measured the rotational diffusion of the cring as a function of temperature to evaluate the change in the rotation angles of the c-ring around the z-axis in clock-and counter-clockwise directions. Our results suggest that the rotational diffusion of the c-ring is temperature-dependent, and the ATP6 extension exacerbates the difference in rotational diffusion at varying temperatures.

description: The apparent stochasticity of in-vivo neural circuits has long been hypothesized to represent a signature of ongoing stochastic inference in the brain. More recently, a theoretical framework for neural sampling has been proposed, which explains how sample-based inference can be performed by networks of spiking neurons. One particular requirement of this approach is that the neural response function closely follows a logistic curve. Analytical approaches to calculating neural response functions have been the subject of many theoretical studies. In order to make the problem tractable, particular assumptions regarding the neural or synaptic parameters are usually made. However, biologically significant activity regimes exist which are not covered by these approaches: Under strong synaptic bombardment, as is often the case in cortex, the neuron is shifted into a high-conductance state (HCS) characterized by a small membrane time constant. In this regime, synaptic time constants and refractory periods dominate membrane dynamics. The core idea of our approach is to separately consider two different "modes" of spiking dynamics: burst spiking and transient quiescence, in which the neuron does not spike for longer periods. We treat the former by propagating the PDF of the effective membrane potential from spike to spike within a burst, while using a diffusion approximation for the latter. We find that our prediction of the neural response function closely matches simulation data. Moreover, in the HCS scenario, we show that the neural response function becomes symmetric and can be well approximated by a logistic function, thereby providing the correct dynamics in order to perform neural sampling. We hereby provide not only a normative framework for Bayesian inference in cortex, but also powerful applications of low-power, accelerated neuromorphic systems to relevant machine learning tasks.

description: We theoretically investigate effect of a transverse electric field generated by side gates and a vertical electric field generated by top, back gates on energy bands and transport properties of zigzag bilayer graphene ribbons (Bernal stacking). Using atomistic Tight Binding calculations and Green function formalism we demonstrate that bandgap is opened when either field is applied and even enlarged under simultaneous influence of the two fields. Interestingly, although vertical electric fields are widely used to control bandgap in bilayer graphene, here we show that transverse fields exhibit more positive effect in terms of modulating a larger range of bandgap and retaining good electrical conductance. Seebeck effect is also demonstrated to be enhanced strongly about 13 times for a zigzag bilayer graphene ribbons with 16 chain lines. These results may motivate new designs of devices made of bilayer graphene ribbons using electric gates.

LA FUNZIONE DELLA MUSICA NEL TEATRODANZA DI SASHA WALTZ E PINA BAUSCH.

Publisher: name: Universit� degli Studi di Milano
Year: 2013

description: The goal of this project is to re-examine the relationships between movement and musical form in contemporary dance theatre, placing the focus of our analysis on the reception that is on the global effect of spectacle. The focal point of romantic ballet was dancers virtuosity, that?s why ? grounding on some ?low quality? scores ? ballet music wasn?t considered as dignified as absolute music, wrongly so. At the beginning of 20th century, esthetical, technical, historical and sociological factors determined a turning point, which, instead, allowed gestures to express the affects: K�rperkultur, a tradition that comes from the Delsartian theory, permitted dance to acquire expressive sense. Starting from Rudolf Laban, dance becomes an independent art form, concentrating on bodily expression: music was no more the inspirer of the movement, but becomes a sort of ?external entity?, giving it only time and rhythmic limits. In the first chapter we contemplate the historical premises, together with the dancers and choreographers ? such as Isadora Duncan, Mary Wigman, Lo�e Fuller, Ruth St. Denis, Kurt Joos and Valentine de Saint-Point ? who led off the development of modern dance in Europe. They prepared the grounds for the different dance theatre conceptions to come: dance theatre is a form of performance, in which dance, words, gestures and movement coexist, as well as music, which ? as stated by Pina Bausch, the ?inventor? of this kind of performance ? is a very important component of the dance spectacle. This project will examine exclusively the production of two choreographers, Pina Bausch and Sasha Waltz, who is viewed by some scholars in a way the heiress of the former. We will take into account only some pieces of their whole production: for Bausch Orpheus und Eurydike, (one of her first creations) Kontakthof in the three 1978, 2000 and 2008 versions and Vollmond, one of her last pieces. We didn?t choose Waltz? more abstract creations, but those of her last periods, on classical music, namely Dido and Aeneas, insideout and Jagden und Formen. Confronting the different musical demands of both choreographers and the way they built the movement sequences, in chapter 4 to 9 we will analyse piece by piece the musical score and the choreography, trying to discover how the relationships between music and movement develop in the spectacles taken into consideration: in opera as well as in non-narrative performances. As a methodological basis in comparing those structures, we will use the principles given by Paul Hodgins and Stephanie Jordan. Exposed in chapter three, the global significance, which is produced by the interaction between music and dance will then be analysed according to the audiovisual studies of Nicholas Cook.

Forensic interpretation of grouped and ungrouped single-cell electropherograms
Creators: name: Mulcahy, Madison Maria
Publisher: name: No Publisher Supplied
Year: 2023

description: In forensic DNA the weight of evidence (WoE) for a person of interest (PoI) is summarized by the logarithm of the likelihood ratio (LR), which is the probability of the data given that the PoI contributed divided by the probability of the data given a random contributor. Manually determining this ratio quickly becomes untenable as the number of peaks increases, the profile shows signs of degradation, or one or more contributors donated low quantities of DNA. As the profile becomes more complex, many genotype combinations can explain the data, meaning that as the peaks increase the WoE will decrease when the PoI is a true contributor to the mixture. An alternative to bulk mixture interpretation is one that focusses on separating the cells before the DNA. By applying a single cell approach the interpretation, in principle, reduces to its simplest form – one that determines a WoE for only one contributor. This work describes a single cell forensic process capable of interpreting single cell EPGs (scEPGs) in a forensically relevant way. We, first, demonstrate scEPGs regularly carry sufficient genetic information to provide informative WoE. We accomplish this by calculating the logLR for each scEPG and true contributor, logLR(E,strue), and show that the majority of scEPGs render values greater than zero. We evaluated the performance of a three-step single-cell interpretation strategy. In the first step scEPGs are clustered in a PoI-agnostic way using unsupervised learning. The second step applied a probabilistic approach to calculate the WoE of each cluster. In the third step we determine the WoE for the entire admixture of cells by averaging the WoE across PoI. To test the interpretation system, we generated 630 cellular admixtures by randomly combining scEPGs of known genotype of varying complexity, where the mixtures contained up to five contributors, consisted of major-minor and equal donor ratios, and were sourced from blood or saliva. We present results that demonstrate that not only was the clustering approach accurate in most cases, but that the WoE for the admixtures remained unaffected by the complexity of the admixture, with 99.0% of the results rendering a logLR > 5.

description: We propose two approaches to cloak the spin waves (magnons) by investigating magnetization dynamics. One approach is based on a spatially inhomogeneous anisotropic magnetic moment tensor. The other mechanism is using a spatially inhomogeneous anisotropic gyromagnetic factor tensor and an inhomogeneous external magnetic field. For both approaches, the damping tensor is also inhomogeneous and anisotropic. The magnetic characteristic functions of the magnetic materials have been theoretically derived for both mechanisms. A non-magnetic core, which prevents magnons from entering and consequently distorts the spin wave propagation, can be cloaked by a structured magnetic shell to redirect the spin wave around the core using the above design mechanisms. We discuss the feasibility of the proposed mechanisms in an ensemble of quantum dot molecules and magnetic semiconductors. The proposed approaches shed light on transformation magnonics, and can be utilized for future spin-wave lenses, concentrators, low back-scattering waveguides, and ultimately quantum computing.

We analyze the local minima of the modified functional as well as the convergence of the modified functional to the original functional. Algorithms combining soft thresholding with gradient descent are proposed for minimizing this new functional. Numerical tests validate our approach. As an added bonus, we also prove the unanticipated and remarkable property that every local minimum the OMM functional without the $\ell^1$ term is also a global minimum.

description: Despite numerous benefits, students do not always respond positively and engage in active learning in STEM courses. Understanding the factors that influence how students’ respond to active learning is important to devising interventions that support their learning, especially for students from historically underrepresented groups. This study examines the influence of students’ belongingness and self-efficacy on their affective and behavioural response to active learning and the moderating influence of students’ gender-identity. We surveyed 579 students from 25 Science, Engineering, and Computer Science courses across 14 universities. Using a latent indirect-effect model, we found that belongingness and self-efficacy independently predicted students’ affective response to active learning and evaluation of the class. Belongingness also predicted students’ self-reports of their behavioural participation in active learning. Using measurement invariance, we also found that, despite mean differences in value, positivity, and distraction, there were no gender differences in the strength of relations between variables. These findings suggest that belongingness and self-efficacy play an important role in how all students respond to active learning and that fostering an atmosphere that supports both may reduce student’s resistance to engaging in active learning.

description: The medium-long term frequency stability of the integrating sphere cold atom clock was improved.During the clock operation, Rb atoms were cooled and manipulated using cooling light diffusely reflected by the inner surface of a microwave cavity in the clock. This light heated the cavity and caused a frequency drift from the resonant frequency of the cavity. Power fluctuations of the cooling light led to atomic density variations in the cavity's central area, which increased the clock frequency instability through a cavity pulling effect. We overcame these limitations with appropriate solutions. A frequency stability of 3.5E-15 was achieved when the integrating time ? increased to 2E4 s.

description: La intensificación de la agricultura ha conllevado a una excesiva dependencia del control químico, frecuentemente utilizado de forma indiscriminada para el control sistemático de plagas. A pesar de los beneficios inmediatos, esta estrategia está llegando a límites para mantener la seguridad alimentaria de una población humana en crecimiento. El progreso en la evaluación toxicológica de los pesticidas ha llevado a restricciones en su uso en el medio ambiente. Por lo que se han buscado nuevas estrategias, de las cuales los biopesticidas basados en agentes de control biológico de origen microbiano (hongos y bacterias) antagonistas de enfermedades de los cultivos, son una alternativa excelente y sostenible para reducir la dependencia global de los productos fitosanitarios convencionales (químicos). No obstante, la producción y uso a gran escala de estos microorganismos biocontroladores presenta algunas dificultades, debido a factores ambientales y a las técnicas utilizadas para su aplicación en campo, afectando negativamente la estabilidad y la viabilidad de los mismos. Por tal motivo, se han investigado nuevos métodos de formulación, especialmente la microencapsulación, la cual ha mostrado un notable aumento en los últimos años. De igual manera se han propuesto una amplia gama de materiales con el propósito de encapsular células microbianas, la selección juiciosa de materiales para la producción de micropartículas es fundamental para garantizar un daño mínimo a la viabilidad de las células microbianas encapsuladas. Dentro de las tecnologías más comúnmente aplicadas para la microencapsulación tenemos: la gelificación iónica, secado por aspersión, emulsificación y coacervación; de otro lado, el lecho fluido es una técnica modificada del secado por aspersión, utilizada para la microencapsulación de probióticos. Los conocimientos y avances de las formulaciones probióticas sirven como referencia para su aplicación en biopreparados conteniendo microorganismos controladores de plagas. El objetivo de esta revisión fue compilar información detallada sobre los materiales y técnicas utilizadas para la microencapsulación de biocontroladores. 2 También se hace una breve revisión de los métodos de secado y los métodos para medir la viabilidad. Se finaliza esta monografía con las aplicaciones recientes y técnicas utilizadas para la microencapsulación de biocontroladores y su utilidad agronómica. En la presente revisión encontramos aplicaciones para todas las técnicas con excepción a la tecnología de lecho fluido, del cual solamente encontramos referencia de su utilización en granulados conteniendo biocontroladores.

description: Remotely sensed data are sparse, which means that data have missing values, for instance due to cloud cover. This is problematic for applications and signal processing algorithms that require complete data sets. To address the sparse data issue, we present a new gap-fill algorithm. The proposed method predicts each missing value separately based on data points in a spatio-temporal neighborhood around the missing data point. The computational workload can be distributed among several computers, making the method suitable for large datasets. The prediction of the missing values and the estimation of the corresponding prediction uncertainties are based on sorting procedures and quantile regression. The algorithm was applied to MODIS NDVI data from Alaska and tested with realistic cloud cover scenarios featuring up to 50% missing data. Validation against established software showed that the proposed method has a good performance in terms of the root mean squared prediction error. The procedure is implemented and available in the open-source R package gapfill. We demonstrate the software performance with a real data example and show how it can be tailored to specific data. Due to the flexible software design, users can control and redesign major parts of the procedure with little effort. This makes it an interesting tool for gap-filling satellite data and for the future development of gap-fill procedures.

description: Despite the advances made in artificial intelligence, software agents, and robotics, there is little we see today that we can truly call a fully autonomous system. We conjecture that the main inhibitor for advancing autonomy is lack of trust. Trusted autonomy is the scientific and engineering field to establish the foundations and ground work for developing trusted autonomous systems (robotics and software agents) that can be used in our daily life, and can be integrated with humans seamlessly, naturally and efficiently. In this paper, we review this literature to reveal opportunities for researchers and practitioners to work on topics that can create a leap forward in advancing the field of trusted autonomy. We focus the paper on the `trust' component as the uniting technology between humans and machines. Our inquiry into this topic revolves around three sub-topics: (1) reviewing and positioning the trust modelling literature for the purpose of trusted autonomy; (2) reviewing a critical subset of sensor technologies that allow a machine to sense human states; and (3) distilling some critical questions for advancing the field of trusted autonomy. The inquiry is augmented with conceptual models that we propose along the way by recompiling and reshaping the literature into forms that enables trusted autonomous systems to become a reality. The paper offers a vision for a Trusted Cyborg Swarm, an extension of our previous Cognitive Cyber Symbiosis concept, whereby humans and machines meld together in a harmonious, seamless, and coordinated manner.

description: Organization studies have long built a ‘business case’ for diversity, which today includes innovation capacity among the benefits of diverse workforces. Diversity’s impact on innovation has been tested in private firms, yet no systematic study exists in public management. We address this challenge using a twostep dynamic panel data analysis via generalised methods of moments estimation in 36 European countries. The findings confirm that higher public workforce diversity leads to higher public sector innovation. This effect, however, is mediated by the administrative ecosystem, where greater uniformity in managerial practices makes diversity more salient, an obstacle to unleash its innovative potential.

description: Natural gas stands as an indispensable energy source, integrated to the daily operations of countries worldwide, serving as a primary energy input for various industries, homes, and sectors. The predominant driver behind the escalating trend in natural gas consumption is rooted in its distinctive environmental profile, characterized by a relatively lower carbon emissions footprint. Recognized as the most environmentally friendly among fossil fuels, natural gas has become the preferred choice, reflecting a conscious effort to mitigate environmental impact and promote sustainability in energy consumption patterns in the world. Especially, in developing countries like Turkey, effective management of energy resources and the formulation of policies centered on the production and consumption of natural gas necessitate accurate forecasting. This study, thus, focuses on forecasting natural gas consumption in Turkey, employing the Fractional Nonlinear Grey Bernoulli Model (FANGBM(1,1)) optimized by Grey Wolf Optimizer (GWO). First, the parameters are optimized using GWO for an accurate forecasting to be used through the metaheuristic model FANGBM(1,1). After using GWO-FANGBM(1,1) model to forecast natural gas consumption in Turkey, a comparative study has been performed including GM(1,1) and GWO-GM(1,1). The predictive performance of these models is compared with ARIMA and linear regression. Notably, numerical results reveal that the proposed hybrid model GWO-FANGBM(1,1) model surpasses other grey models, such as GM(1,1) and GWO-GM(1,1), as well as statistical methods like ARIMA and linear regression. Numerical results show that the proposed hybrid model, GWO-FANGBM(1,1), achieves superior prediction accuracy with a MAPE of 5.82%, an RMSE of 3857.12, and an MAE of 3062.00, outperforming GM(1,1), GWO-GM(1,1), ARIMA, and LR. The originality of the study is supported by the fact that a hybrid approach named as GWO-FANGBM(1,1) has not been used in the literature to forecast natural gas consumption in Turkey with an accurate parameter optimization.

description: Purpose of Project: The purpose of this project was to integrate inhaled lavender aromatherapy prior to gynecological examinations in an effort to decrease pain and anxiety. Methodology: Quasi-experimental design with pre-/post-test including all English-speaking women ages 21-75 presenting for gynecological examinations. Participants received educational brochure explaining benefits of lavender aromatherapy and positive effects on decreasing levels of pain and anxiety, followed by inhaled lavender aromatherapy 15 minutes before gynecological exam, and data collection using visual analog scale and state trait anxiety scale questionnaires. Participant likelihood of returning for next exam with the presence of aromatherapy also assessed. Results: Total of 34 participants partook in the inhalation of lavender before their gynecological exam. There were statistically significant changes in anxiety after the gynecological exams (p =.010) and in state trait anxiety scale score after the lavender (p =.012). While there was a reduction in pain after gynecological exams, results failed to reach statistical significance (p =.423). All participants acknowledged intent to return for future gynecological exams with the presence of lavender aromatherapy. Implications for Practice: Implications for practice include increased gynecological exam compliance, more positive relationship with providers and overall decreased pain and anxiety during exams. Additionally, improving overall participant experience, and increased adherence to recommended guidelines regarding gynecological exam compliance.

description: Introducing the DRAGON simulation project, we present direct $N$-body simulations of four massive globular clusters (GCs) with $10^6$ stars and 5$\%$ primordial binaries at a high level of accuracy and realism. The GC evolution is computed with NBODY6++GPU and follows the dynamical and stellar evolution of individual stars and binaries, kicks of neutron stars and black holes, and the effect of a tidal field. We investigate the evolution of the luminous (stellar) and dark (faint stars and stellar remnants) GC components and create mock observations of the simulations (i.e. photometry, color-magnitude diagrams, surface brightness and velocity dispersion profiles). By connecting internal processes to observable features we highlight the formation of a long-lived 'dark' nuclear subsystem made of black holes (BHs), which results in a two-component structure. The inner core is dominated by the BH subsystem and experiences a core collapse phase within the first Gyr. It can be detected in the stellar (luminous) line-of-sight velocity dispersion profiles. The outer extended core - commonly observed in the (luminous) surface brightness profiles - shows no collapse features and is continuously expanding. We demonstrate how a King (1966) model fit to observed clusters might help identify the presence of post core-collapse BH subsystems. For global observables like core and half-mass radii the direct simulations agree well with Monte-Carlo models. Variations in the initial mass function can result in significantly different GC properties (e.g. density distributions) driven by varying amounts of early mass loss and the number of forming BHs.
