description: After about two decades of the first observational papers confirming the accelerated expansion of the universe, we are still facing the question whether the cause of it is a rigid cosmological constant $Λ$-term or a mildly evolving dynamical dark energy (DDE). While studies focusing mainly on CMB measurements do not perceive signs of physics beyond the $Λ$CDM, in this work we show that if we take a large string $SNIa+BAO+H(z)+LSS+CMB$ of modern cosmological observations, in which not only the CMB but also a rich sample of large scale structure formation data are included, one can extract $\sim 3.3σ$ signs of DDE using a simple XCDM parameterization. These signs can be enhanced up to near $3.8σ$ in the context of the running vacuum model (RVM), in which the vacuum energy density is in interaction with dark matter. Recently the RVM has been shown to provide an efficient and economical solution to the $σ_8$-tension, which is one of the intriguing phenomenological problems that has not been possible to solve within the $Λ$CDM so far. This fact contributes to strengthen the possibility that dynamical vacuum energy, or in general DDE, could be presently favored by the observations.

description: The Human resource data (HRDt) is considered a valuable asset for an organization; however, its effect is more significant when utilized in a proper way. This research study is conducted in Statistics and Measurement Unit (SAMU) at X Public Administration, Sultanate of Oman, Muscat. The primary aim of the study is to identify the internal issues and challenges related to the usage of HRDt at the SAMU in the Sultanate of Oman. In addition, a further aim is to increase the effectiveness of the SAMU by improving the usage of HRDt and utilizing it in the human resource (HR) decision-making process (DMP). Furthermore, the study aims include the identification of the reasons behind the lack of data usage at the SAMU, the evaluation of the culture role in the usage of the data, the identification of any force from managers to ignore the data, and an evaluation of whether the usage of data in the DMP improves or has any effect on staff satisfaction. The study followed a pragmatist research philosophy, an inductive research approach, and an AR strategy. The data was collected using a multiple-method qualitative strategy research choice by observing the participants and conducting semi-structured interviews. Thematic analysis techniques were used to analyze the collected qualitative data. The findings of the research study were above the expectations and actionable, which provided reasons for ignoring the usage of HRDt in the HR decision-making process. Furthermore, the creation of the network between the organizational units showed the effectiveness of various processes. Moreover, the study encourages not only the AR Team, but also the new senior managers to adopt the AR methodology as a tool for solving organizational problems for which the organization created a new unit specialist to gather AR proposals, provide approvals, and discuss the results and the solutions. Ethical approvals and consideration were obtained from the ethics review board of the University of Liverpool and the X Public Administration before conducting the research study. The limitations of the study include the fact that the implementation of the study’s outcome was applied to a single unit within the organization due to the COVID-19 pandemic restrictions; however, the limitation was overcome by involving other units’ managers in the study as AR Team so they can transfer, report the knowledge and the idea to their units. Furthermore, the number of the AR Team was limited to 10 due to the fact that in general X Public Administration is known for the lowest number of staff compared to other governmental organizations in the country; nevertheless, despite this limitation, the study was conducted successfully.

description: Organizations are now integrating life cycle thinking tools and techniques into decision-making to enable an analysis of the environmental impacts associated with all stages of a product’s life. In this context, mining has been questioned by the widespread consensus that reducing resource consumption is a requirement for sustainable development. On the other side, it is clear that, due to dissipation, virgin raw materials will always be needed, and that circular economy thinking should integrate the mining industry and not oppose it. From this emerges the concern of resource depletion and the abiotic depletion potential (ADP) comes therefore as an attempt to assess the risk of depletion within life cycle assessment (LCA) methodology. However, when it comes to mineral resources, a lot of general assumptions are made, and the specificities of each element are often neglected. By attempting to include anthropogenic stocks in the calculations, some authors also neglect the singularities of each product. LCA has proven to be a powerful tool and its successful application within the refractory industry depends on collaboration between organisations in order to fill the numerous lacks of data availability and to overcome the challenges ahead. This paper is part of a PhD project that aims to build a database of magnesia production, from the mine to the kiln, to support LCA as well as to discuss resource depletion within the methodology and to account for the benefits and challenges of refractory recycling, focusing on magnesia bricks.

description: We advance a holographic conjecture for the entanglement negativity of bipartite quantum states in $(1+1)$-dimensional conformal field theories in the $AdS_3/CFT_2$ framework. Our conjecture exactly reproduces the replica technique results in the large central charge limit, for both the pure state described by the $CFT_{1+1}$ vacuum dual to bulk the pure $AdS_3$ geometry and the finite temperature mixed state dual to a Euclidean BTZ black hole respectively. The holographic entanglement negativity characterizes the distillable entanglement and reduces to a specific sum of holographic mutual informations. We briefly allude to a possible higher dimensional generalization of our conjecture in a generic $AdS_{d+1}/CFT_{d}$ scenario.

Predicting grammatical gender in Nakh languages: Three methods compared

description: The Nakh languages Chechen and Tsova-Tush each have a five-valued gender system: masculine, feminine, and three “neuter” genders named for their singular agreement forms: B, D and J. Gender assignment in languages is generally analysed as being dependent on both forms and semantics (e.g. Corbett, 1991), with semantics typically prevailing over form (e.g. Bellamy & Wichers Schreur, 2021, Allassonnière-Tang et al., 2021). Most previous studies have considered only binary or tripartite gender systems possessing masculine, feminine, and neuter values. The five-valued system of Nakh thus represents an innovative and insightful case study for analysing gender assignment. In this paper we build on the existing qualitative linguistic analyses of gender assignment in Tsova-Tush (Wichers Schreur, 2021) and apply three machine-learning methods to investigate the weight of form and semantics in predicting grammatical gender in Chechen and Tsova-Tush. The results show that while both form and semantics are helpful for predicting grammatical gender in Nakh, semantics is dominant, which supports findings from existing literature (Allassonnière-Tang, Brown & Fedden, 2021). However, the results also show that the coded semantic information could be further fine-grained to improve the accuracy of the predictions (see also Plaster et al., 2013). In addition, we discuss the implications of the output for our understanding of language-internal and family-internal processes of language change, including how loanwords are integrated from Russian, a three-gender language.

description: We study the behavior of the complex potential between a heavy quark and its antiquark, which are in relative motion with respect to a hot and dense medium. The heavy quark-antiquark complex potential is obtained by correcting both the Coulombic and the linear terms in the Cornell potential through a dielectric function estimated within the real-time formalism using the hard thermal loop approximation. We show the variation of both the real and the imaginary parts of the potential for different values of velocities when the bound state ($ Q\bar{Q}$ pair) is aligned in the direction parallel as well as perpendicular to the relative velocity of the $ Q\bar{Q}$ pair with the thermal medium. With an increase of the relative velocity the screening of the real part of the potential becomes weaker at short distances and stronger at large distances for the parallel case. However, for the perpendicular case the potential decreases with an increase of the velocity at all distances which results in the larger screening of the potential. In addition, the inclusion of the string term makes the screening of the potential weaker as compared to the Coulombic term alone for both cases. Therefore, by combining all these effects we expect a stronger binding of a $ Q\bar{Q} $ pair in a moving medium in the presence of the string term as compared to the Coulombic term alone. The imaginary part decreases (in magnitude) with an increase of the relative velocity, leading to a decrease of the width of the quarkonium state at higher velocities. The inclusion of the string term increases the magnitude of the imaginary part, which results in an increase of the width of the quarkonium states. All of these effects lead to the modification in the dissolution of quarkonium states.

description: The time of concentration is an important concept in hydrology. It provides a characteristic hydrological response time (CHRT) useful in many applications. Estimation of the time of concentration is challenging because small watersheds (<100 km2) with sub-daily flow and precipitation records are uncommon. Many practitioners therefore use empirical equations developed from watersheds exposed to different climates and with different attributes. The main objective of this study is to develop an approach to estimate the CHRT from physiographic characteristics for small watersheds located in Ontario, Québec and the northeastern USA. Regression trees are used to identify the physiographic characteristics associated with CHRT. The fraction of lakes and wetlands was identified as the most significant attribute related to CHRT, followed by the ratio between the main watercourse length and the square root of the main watercourse slope. Uncertainties on estimated CHRT values based on regression tree are also provided.

description: This report presents the development of two international bunker fuel models, for maritime and aviation that can assess the potential contribution of the sectors to meet deep decarbonization goals such as those of the Paris Agreement objectives. The models are calibrated to latest available information. In the short-term both models take into account the impact of the COVID-19 pandemic, and include mechanisms that can account for different policies, technologies, and prices. We quantify global and regional scenarios as well as regional case studies to demonstrate the potential contribution of international bunker fuels to GHG mitigation efforts. Then, the report discusses how the modelling of international transport (aviation and shipping) is improved in the global energy model PROMETHEUS, with endogenization of the emission reduction options (e.g., accelerated efficiency and operational improvements, advanced biofuels, clean synthetic fuels, hydrogen). Finally, the enhanced global modelling framework was used to investigate deep decarbonisation pathways and strategies for the international shipping and aviation sectors highlighting feasible policy measures and actions in the relatively short-term and possible enhancements in the longer-term, as well as the synergies of domestic climate action with the decarbonisation of bunker fuels.

description: In this work we focus on the gravitationally influenced adiabatic particle creation process, a mechanism that does not need any dark energy or modified gravity models to explain the current accelerating phase of the universe. Introducing some particle creation models that generalize some previous models in the literature, we constrain the cosmological scenarios using the latest compilation of the Type Ia Supernovae data only, the first indicator of the accelerating universe. Aside from the observational constraints on the models, we examine the models using two model independent diagnoses, namely the cosmography and $Om$. Further, we establish the general conditions to test the thermodynamic viabilities of any particle creation model. Our analysis shows that at late-time, the models have close resemblance to that of the $Λ$CDM cosmology, and the models always satisfy the generalized second law of thermodynamics under certain conditions.

description: In the paper, we show how to tackle the problem of lack of the rotation invariance in CNN networks using the authors’ Invariant Dataset Augmentation (IDA) method. The IDA method allows to increase the clas-sification rates taking into account as an example the classification of the skin lesions using a small image set. In order to solve the problem of the lack of rotation invariance, IDA method was used and the dataset was in-creased in an eightfold and invariant way. In the research, we applied the IDA methods and compared the results of VGG19, XN and Inception-ResNet-v2 CNN networks in three skin lesions features classification defined by well-known dermoscopic criterions e.g. the Three-Point Checklist of Dermoscopy or the Seven-Point Checklist. Due to Invariant Dataset Augmentation, the classification rate parameters like true positive rate by almost 20%, false positive rate as well as the F1 score and Matthews correlation coefficient have been significantly increased opposite to type II error that has signifi-cantly decreased. In the paper, the confusion matrix parameters result in: 98-100% accuracy, 98-100% true positive rate, 0.0-2.3% false positive rate, tests F1=0.95 and MCC=0.95. That general approach can provide higher results while using CNN networks in other applications.

Im Falle der Naturstoffe Isomigrastatin sowie Lactimidomycin wurde im Anschluss an diese eine trans-selektive Hydrosilylierung/Protodesilylierung zum Erhalt eines E-Alkens durchgeführt. Im Rahmen der Synthese von Dehydrocurvularin erlaubte eine Ausweitung der RCAM auf funktionalisierte propargylische Alkohole die Darstellung eines zyklischen E-Enons. Schließlich diente eine der RCAM folgende Edelmetall-katalysierte Heterozyklisierung zur Bildung eines Benzofurans als entscheidender Schritt in der Synthese des Antibiotikums Kendomycin. Eine sich den synthetischen Arbeiten anschließende biologische Evaluierung offenbarte für einige der dargestellten Substanzen eine unerwartet hohe Zytotoxizität gegenüber menschlichen und murinen Krebszelllinien.

description: We consider a quantum system periodically driven with a strength which varies slowly on the scale of the driving period. The analysis is based on a general formulation of the Floquet theory relying on the extended Hilbert space. It is shown that the dynamics of the system can be described in terms of a slowly varying effective Floquet Hamiltonian that captures the long-term evolution, as well as rapidly oscillating micromotion operators. We obtain a systematic high-frequency expansion of all these operators. Generalizing the previous studies, the expanded effective Hamiltonian is now time-dependent and contains extra terms appearing due to changes in the periodic driving. The same applies to the micromotion operators which exhibit a slow temporal dependence in addition to the rapid oscillations. As an illustration, we consider a quantum-mechanical spin in an oscillating magnetic field with a slowly changing direction. The effective evolution of the spin is then associated with non-Abelian geometric phases reflecting the geometry of the extended Floquet space. The developed formalism is general and also applies to other periodically driven systems, such as shaken optical lattices with a time-dependent shaking strength, a situation relevant to the cold atom experiments.

description: In this paper, we develop the mathematical tools needed to explore isotopy classes of tilings on hyperbolic surfaces of finite genus, possibly nonorientable, with boundary, and punctured. More specifically, we generalize results on Delaney–Dress combinatorial tiling theory using an extension of mapping class groups to orbifolds, in turn using this to study tilings of covering spaces of orbifolds. Moreover, we study finite subgroups of these mapping class groups. Our results can be used to extend the Delaney–Dress combinatorial encoding of a tiling to yield a finite symbol encoding the complexity of an isotopy class of tilings. The results of this paper provide the basis for a complete and unambiguous enumeration of isotopically distinct tilings of hyperbolic surfaces.
Search for heavy resonances decaying to tau lepton pairs in proton-proton collisions at sqrt(s) = 13 TeV

description: A search for heavy resonances that decay to tau lepton pairs is performed using proton-proton collisions at sqrt(s) = 13 TeV. The data were collected with the CMS detector at the CERN LHC and correspond to an integrated luminosity of 2.2 inverse femtobarns. The observations are in agreement with standard model predictions. An upper limit at 95% confidence level on the product of the production cross section and branching fraction into tau lepton pairs is calculated as a function of the resonance mass. For the sequential standard model, the presence of Z' bosons decaying into tau lepton pairs is excluded for Z' masses below 2.1 TeV, extending previous limits for this final state. For the topcolor-assisted technicolor model, which predicts Z' bosons that preferentially couple to third-generation fermions, Z' masses below 1.7 TeV are excluded, representing the most stringent limit to date.

description: Theta functions for definite signature lattices constitute a rich source of modular forms. A natural question is then their generalization to indefinite signature lattices. One way to ensure a convergent theta series while keeping the holomorphicity property of definite signature theta series is to restrict the sum over lattice points to a proper subset. Although such series do not have the modular properties that a definite signature theta function has, as shown by Zwegers for signature $(1,n-1)$ lattices, they can be completed to a function that has these modular properties by compromising on the holomorphicity property in a certain way. This construction has recently been generalized to signature $(2,n-2)$ lattices by Alexandrov, Banerjee, Manschot, and Pioline. A crucial ingredient in this work is the notion of double error functions which naturally lends itself to generalizations to higher dimensions. In this work we study the properties of such higher dimensional error functions which we will call $r$-tuple error functions. We then construct an indefinite theta series for signature $(r,n-r)$ lattices and show they can be completed to modular forms by using these $r$-tuple error functions.

description: In [5], Donovan and Wemyss introduced the contraction algebra of flopping curves in 3-folds. They conjectured that the contraction algebra determines the formal neighborhood of the underlying singularity of the contraction. In this paper, we prove that the contraction algebra together with its natural $A_\infty$-structure constructed in [10], determine the formal neighborhood of the singularity.

description: Humanitarian and health crisis have drastic effects on the physical and mental well-being of people. The COVID-19 pandemic forced many countries to impose containment measures on its population to halt the spread of the new coronavirus (SARS-CoV-2). This aim of this study was to explore self-reported sleep quality and insomnia symptoms in a sample of the Brazilian population before and during the COVID-19 quarantine period. Our data was collected through online questionnaires, including the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and the Sleep Hygiene Index. The final sample comprised 1,109 volunteers. Generalized estimating equations (GEE) revealed that during the initial months of the COVID-19 pandemic, alterations in self-reported sleep parameters were observed in the participants. Sleep efficiency and sleep duration increased, but there was a worsening in sleep quality and an increase in symptoms related to insomnia.

description: In this paper, we investigate the effects of a new version of the generalized uncertainty principle (modified GUP) on the dynamics of the Universe. As the modified GUP will modify the relation between the entropy and area of the apparent horizon, it will also deform the Friedmann equations within Jacobson's approach. We explicitly find these deformed Friedmann equations governing the modified GUP-corrected dynamics of such a Universe. It is shown that the modified GUP-deformed Jacobson's approach implies an upper bound for the density of such a Universe. The Big Bang singularity can therefore also be avoided using the modified GUP-corrections to horizons' thermodynamics. In fact, we are able to analyze the pre Big Bang state of the Universe. Furthermore, the equations imply that the expansion of the Universe will come to a halt and then will immediately be followed by a contracting phase. When the equations are extrapolated beyond the maximum rate of contraction, a cyclic Universe scenario emerges.

description: Desynchronization of circadian rhythms and sleep-wake patterns impacts biochemical, physiological, and behavioral functions, including mental processes. The complex relationship between circadian rhythms and mental health makes it challenging to determine causality between circadian desynchronization and mental disorders. Regarding the fact that psychologists act as the front line for initial mental health care, we aimed to assess the knowledge and use of sleep science and basic chronobiology by professional psychologists in Brazil. Data were collected via an online questionnaire completed by 1384 professional psychologists between October 2018 and May 2019. Our findings revealed that ±80% of psychologists reported that at least half of their patients presented some sleep-related complaints; however, only ±27% routinely inquired about sleep quality even in the absence of patient complaints. Additionally, only ±66% initiated treatments to understand these complaints, potentially influenced by the lack of prior academic exposure to biological rhythms as reported by ±76% of Brazilian psychologists interviewed. Importantly, ±15% did not believe in an association between mental health and biological rhythms, and even a significant ±67% were unfamiliar with the term chronobiology and ±63% were not able to describe any other biological rhythm except for the sleep-wake cycle. These results demonstrate that fundamental concepts in chronobiology and sleep science are unknown to a substantial proportion of Brazilian psychologists. In conclusion, we propose that this subject could be more effectively integrated into psychologists’ academic training, potentially promoting benefits through the incorporation of a chronobiological approach in mental health practice.

Bond Graph Modelling of Chemiosmotic Biomolecular Energy Transduction

Year: 2016
Subjects: subject: Molecular Networks (q-bio.MN)

description: Engineering systems modelling and analysis based on the bond graph approach has been applied to biomolecular systems. In this context, the notion of a Faraday-equivalent chemical potential is introduced which allows chemical potential to be expressed in an analogous manner to electrical volts thus allowing engineering intuition to be applied to biomolecular systems. Redox reactions, and their representation by half-reactions, are key components of biological systems which involve both electrical and chemical domains. A bond graph interpretation of redox reactions is given which combines bond graphs with the Faraday- equivalent chemical potential. This approach is particularly relevant when the biomolecular system implements chemoelectrical transduction - for example chemiosmosis within the key metabolic pathway of mitochondria: oxidative phosphorylation. An alternative way of implementing computational modularity using bond graphs is introduced and used to give a physically based model of the mitochondrial electron transport chain. To illustrate the overall approach, this model is analysed using the Faraday-equivalent chemical potential approach and engineering intuition is used to guide affinity equalisation: a energy based analysis of the mitochondrial electron transport chain.
