description: Metabolic rates are linked to key life-history traits that are thought to set the pace of life and affect fitness, yet the role that parents may have in shaping the metabolism of their offspring to enhance survival remains unclear. Here, we investigated the effect of temperature (24°C or 30°C) and feeding frequency experienced by parent zebrafish (Danio rerio) on offspring phenotypes and early survival at different developmental temperatures (24°C or 30°C). We found that embryo size was larger, but survival lower, in offspring from the parental low food treatment. Parents exposed to the warmer temperature and lower food treatment also produced offspring with lower standard metabolic rates—aligning with selection on embryo metabolic rates. Lower metabolic rates were correlated with reduced developmental and growth rates, suggesting selection for a slow pace of life. Our results show that intergenerational phenotypic plasticity on offspring size and metabolic rate can be adaptive when parent and offspring temperatures are matched: the direction of selection on embryo size and metabolism aligned with intergenerational plasticity towards lower metabolism at higher temperatures, particularly in offspring from low condition parents. These findings provide evidence for adaptive parental effects, but only when parental and offspring environments match.This article is part of the theme issue ‘Evolutionary significance of variation in metabolic rates’.

description: We have observed the Crab pulsar with the Deep Space Network (DSN) Goldstone 70 m antenna at 1664 MHz during three observing epochs for a total of 4 hours. Our data analysis has detected more than 2500 giant pulses, with flux densities ranging from 0.1 kJy to 150 kJy and pulse widths from 125 ns (limited by our bandwidth) to as long as 100 microseconds, with median power amplitudes and widths of 1 kJy and 2 microseconds respectively. The most energetic pulses in our sample have energy fluxes of approximately 100 kJy-microsecond. We have used this large sample to investigate a number of giant-pulse emission properties in the Crab pulsar, including correlations among pulse flux density, width, energy flux, phase and time of arrival. We present a consistent accounting of the probability distributions and threshold cuts in order to reduce pulse-width biases. The excellent sensitivity obtained has allowed us to probe further into the population of giant pulses. We find that a significant portion, no less than 50%, of the overall pulsed energy flux at our observing frequency is emitted in the form of giant pulses.

description: The 3-strand pretzel knots and links are a well-studied source of examples in knot theory. However, while there have been computations of the Khovanov homology of some sub-families of 3-strand pretzel knots, no general formula has been given for all of them. We give a general formula for the unreduced Khovanov homology of all 3-strand pretzel links, over the rational numbers.

description: Let $F$ be a leafwise hyperbolic taut foliation of a closed 3-manifold $M$ and let $L$ be the leaf space of the pullback of $F$ to the universal cover of $M$. We show that if $F$ has branching, then the natural action of $π_1(M)$ on $L$ is faithful. We also show that if $F$ has a finite branch locus $B$ whose stabilizer acts on $B$ nontrivially, then the stabilizer is an infinite cyclic group generated by an indivisible element of $π_1(M)$.

Homologous Gravitational Collapse in Lagrangian Coordinate: Planetary System in Protostar and Cavity in Pre-Supernova

description: The classical problem of spherical homologous gravitational collapse with a polytropic equation of state for pressure is examined in Lagrangian fluid coordinate, where the position of each initial fluid element η = r(0) is followed in time by the evolution function y(t). In this Lagrangian description, the fluid velocity v = dr/dt = ηdy/dt is not a fluid variable, contrary to the commonly used Eulerian fluid description. As a result, the parameter space is one dimensional in η, in contrast to the (x, v) two-parameter space of Eulerian formulation. In terms of Lagrangian coordinate, the evolution function y(t), which is not limited to a linear time scaling, agrees with the well established parametric form of Mestel (Mestel 1965) for cold cloud collapse. The spatial structure is described by an equation which corresponds to the one derived by Goldreich and Weber (Goldreich & Weber 1980). The continuous self-similar density distribution presents a peaked central core followed by oscillations with decreasing amplitude, somewhat reminiscent to the expansion-wave inside-out collapse of Shu (Shu 1977). This continuous solution could account for the planetary system of a protostar. There is also a disconnected density distribution, which could be relevant to cavity formation between the highly peaked central core and the external infalling envelope of a magnetar-in-a-cavity pre-supernova configuration.

description: Exopolysacharides (EPS) produced by Lactobacillus acidophilus play an important role in food processing with its well-recognized antioxidant activity. In this study, a L. acidophilus mutant strain with high-yielding EPS (2.92±0.05 g/L) was screened by chemical mutation (0.2 % diethyl sulfate). Plackett-Burman (PB) design and response surface methodology (RSM) were applied to optimize the EPS fermentation parameters and central composite design (CCD) was used to optimize the EPS extraction parameters. A strain with high-yielding EPS was screened. It was revealed that three parameters (Tween 80, dipotassium hydrogen phosphate and trisodium citrate) had significant influence (P < 0.05) on the EPS yield. The optimal culture conditions for EPS production were: Tween 80 0.6 mL, dipotassium hydrogen phosphate 3.6 g and trisodium citrate 4.1 g (with culture volume of 1 L). In these conditions, the maximum EPS yield was 3.96±0.08 g/L. The optimal extraction conditions analyzed by CCD were: alcohol concentration 70 %, the ratio of material to liquid (M/L ratio) 1:3.6 and the extraction time 31 h. In these conditions, the maximum EPS extraction yield was 1.48±0.23 g/L. It was confirmed by the verification experiments that the EPS yield from L. acidophilus mutant strains reached 5.12±0.73 g/L under the optimized fermentation and extraction conditions, which was 3.8 times higher than that of the control (1.05±0.06 g/L). The results indicated that the strain screening with high-yielding EPS was successful and the optimized fermentation and extraction conditions significantly enhanced EPS yield. It was efficient and industrially promising.

description: We study how varying the P éclet number (Pe) affects the steady state sedimentation of colloidal particles that interact through short-ranged attractions. By employing a hybrid molecular dynamics simulation method we demonstrate that the average sedimentation velocity changes from a non- monotonic dependence on packing fraction ϕ at low Pe numbers, to a monotonic decrease with ϕ at higher Pe numbers. At low Pe number the pair correlation functions are close to their equilibrium values, but as the Pe number increases, important deviations from equilibrium forms are observed. Although the attractive forces we employ are not strong enough to form permanent clusters, they do induce transient clusters whose behaviour is also affected by Pe number. In particular, clusters are more likely to fragment and less likely to aggregate at larger Pe numbers, and the probability of finding larger clusters decreases with increasing Pe number. Interestingly, the life-time of the clusters is more or less independent of Pe number in the range we study. Instead, the change in cluster distribution occurs because larger clusters are less likely to form with increasing Pe number. These results illustrate some of the subtleties that occur in the crossover from equilibrium like to purely non-equilibrium behaviour as the balance between convective and thermal forces changes.

description: Mass spectrum of 0++ glueballs is produced using a dual supergravity theory we proposed for pure N=1 SU(N) gauge theory in four dimensions in the large N limit in the IR. The glueball states are expressed in terms of Whittaker functions. The spectrum is discrete and a function whose roots give the masses is written. The ratios of the masses are independent of the parameters of the theory and comparison to recent non-supersymmetric large N lattice QCD data available for the lowest three states shows agreement to within five percent.

description: Based on the time-dependent nonequilibrium Green's function method we investigate theoretically the time and spin-dependent transport through a graphene layer upon the application of a static bias voltage to the electrodes and a time-alternating gate voltage to graphene. The electrodes are magnetic with arbitrary mutual orientations of their magnetizations. We find features in the current that are governed by an interplay of the strength of the alternating field and the Dirac point in graphene: The influence of a weak alternating field on the zero bias conductance is strongly suppressed by the zero density of state at the Dirac point. In contrast, for a strong amplitude of the alternating field the current is dominated by several resonant peaks, in particular a marked peak appears at zero bias. This subtle competition results in a transition of the tunnel magnetoresistance from a broad peak to a sharp dip at a zero bias voltage applied to the electrodes. The dip amplitude can be manipulated by tuning the ac field frequency.

description: Aims. We analyze coronagraph observations of a polar jet observed by the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instrument suite onboard the Solar TErrestrial RElations Observatory (STEREO) spacecraft. Methods. In our analysis we compare the brightness distribution of the jet in white-light coronagraph images with a dedicated kinetic particle model. We obtain a consistent estimate of the time that the jet was launched from the solar surface and an approximate initial velocity distribution in the jet source. The method also allows us to check the consistency of the kinetic model. In this first application, we consider only gravity as the dominant force on the jet particles along the magnetic field. Results. We find that the kinetic model explains the observed brightness evolution well. The derived initiation time is consistent with the jet observations by the EUVI telescope at various wavelengths. The initial particle velocity distribution is fitted by Maxwellian distributions and we find deviations of the high energy tail from the Maxwellian distributions. We estimate the jet's total electron content to have a mass between 3.2 \times 1014 and 1.8 \times 1015 g. Mapping the integrated particle number along the jet trajectory to its source region and assuming a typical source region size, we obtain an initial electron density between 8 \times 109 and 5 \times 1010 cm-3 that is characteristic for the lower corona or the upper chromosphere. The total kinetic energy of all particles in the jet source region amounts from 2.1 \times 1028 to 2.4 \times 1029 erg.

description: We formulate the concept of time machine structure for spacetimes exhibiting a compactely constructed region with closed timelike curves. After reviewing essential properties of the pseudo Schwarzschild spacetime introduced by A. Ori, we present an analysis of its geodesics analogous to the one conducted in the case of the Schwarzschild spacetime. We conclude that the pseudo Schwarzschild spacetime is geodesically incomplete and not extendible to a complete spacetime. We then introduce a rotating generalization of the pseudo Schwarzschild metric, which we call the the pseudo Kerr spacetime. We establish its time machine structure and analyze its global properties.

description: Servicing and maintaining wind turbines may expose wind turbine technicians (wind techs) to musculoskeletal disorder (MSD) hazards. We aimed to characterise MSD hazard exposures and identify work elements that should be prioritised for MSD prevention efforts. A cross-sectional online survey methodology gathered data from 144 wind techs based on a convenience, non-probability sampling approach. The survey was developed using resources from the Ontario MSD Prevention Guideline, where cognitive interviewing yielded wind tech specific modifications. Climbing was the most physically demanding task, followed by torqueing/tensioning and manual materials handling (MMH). However, working in awkward and constrained postures emerged as the task most likely to cause or aggravate discomfort. Injecting ergonomic and human factors principles into wind turbine design should be a high priority. Re-engineering tools like torque tensioning devices may reduce MSD hazard exposures associated with tasks including torqueing/tensioning and MMH. We know little about musculoskeletal disorder (MSD) hazards associated with green jobs. By surveying wind turbine technicians, we learned that MSD hazards exists, and can be addressed by better considering human factors/ergonomics principles in the design of wind turbines and the tools required for service and maintenance operations.

TechCare Dairy Goats Welfare Assessment Measures

description: A description of animal-based measures and their definition as used in the dairy goats studies by TechCare. These are NOT intended to be a comprehensive protocol for assessing overall welfare of dairy goats but are individual measures of different welfare issues as identified by the TechCare stakeholders as the most important issues for their industry. As far as possible these are validated indicators drawn from a number of different studies (particularly the Animal Welfare Indicators (AWIN) project, national projects), which were considered the best methods to measure each issue by the TechCare WP2 team. Indicators are described in two ways: firstly, for measures that can be taken in the field in undisturbed animals (typically extensively managed animals where it would not be feasible or desirable to handle the animals frequently) and secondly for those that can be made at close quarters, likely with some handling required (e.g. restraint). Indicators are measured at the level of the individual animal. This is required to allow validation of the sensor measures (which are recorded at the animal level). Thus, each animal must be identifiable at close quarters and at a distance if the field measures are to be used.

description: This is the report of the second FAIRsFAIR Synchronisation Force workshop, organised online as a series of eight sessions from 29th of April until 11th of June 2020. The objective of these sessions was to measure the progress towards implementing the recommendations outlined in the Turning FAIR into Reality report (2018). To do this, FAIRsFAIR brought together representatives of the Working Groups of the EOSC Executive Board, INFRAEOSC5 projects, ESFRI clusters, and the FAIRsFAIR European Group of FAIR Champions to share information on the progress of their FAIR-oriented activities and to discuss commonalities and priorities. The report addresses the EOSC Executive Board and Governing Board and their successors, as well as the European Commission’s EOSC programme (together called “the EOSC Governance” in this report), in addition to the participants and other EOSC-related projects. A table in the document summarises the amount of activity with regards to the 27 recommendations from the Turning FAIR into Reality report (TFiR). It is a snapshot in time and the observations and analysis in the report express an interpretation of the situation - confirmed by the workshop participants. The overall conclusion of the workshop series and this review of project activities is that the implementation of the Turning FAIR into Reality recommendations is clearly being addressed across the range of projects and activities surveyed. The EOSC Governance should look at the less well covered TFiR Recommendations 6, 8, 11 and 13 (coded “some activities support this recommendation”), determine whether extra activity is needed and which could be provided through EOSC co-creation activities, through the Horizon Europe funding initiative or through other means. Workshop participants also felt that supporting recommendation 23 should be reclassified as a priority recommendation. Finally, this report proposes additional actions that address gaps in the Turning FAIR into Reality Action Plan that were identified by the workshop discussions.

description: The effects of magnetic vortices and nonmagnetic impurities on the low energy quasiparticle excitations and the spin-lattice relaxation rate are examined in the iron-based superconductors for the $s_{\pm}$-, $s$- and d-wave pairing symmetries, respectively. The main effect of the vortices is to enhance the quasiparticle excitations and the spin-lattice relaxation rate for all symmetries, and leads to a $T^{3}$ dependence of the relaxation rate followed by a nearly $T$-linearity at lower temperatures. This enhancement can only be seen for the $s_{\pm}$- and d-wave symmetries in the presence of nonmagnetic impurities. These results suggest that the $s_{\pm}$-wave and d-wave pairing states behave similarly in response to the magnetic field and nonmagnetic impurities, therefore it may be impossible to distinguish them on the basis of the measurements of spin-lattice relaxation rates when a magnetic field and/or impurity scatterings are present.

description: We report the results of a systematic survey for 95 GHz class I methanol masers towards a new sample of 192 massive young stellar object (MYSO) candidates associated with ongoing outflows (known as extended green objects or EGOs) identified from the Spitzer GLIMPSE survey. The observations were made with the Australia Telescope National Facility (ATNF) Mopra 22-m radio telescope and resulted in the detection of 105 new 95 GHz class I methanol masers. For 92 of the sources our observations provide the first identification of a class I maser transition associated with these objects (i.e. they are new class I methanol maser sources). Our survey proves that there is indeed a high detection rate (55%) of class I methanol masers towards EGOs. Comparison of the GLIMPSE point sources associated with EGOs with and without class I methanol maser detections shows they have similar mid-IR colors, with the majority meeting the color selection criteria -0.6

Does Teleworking Affect Housework Division And Improve The Well-Being Of Couples?

Subjects: Gender Roles; Household Production; Teleworking; Well-Being

description: This study examines the relationship between teleworking, gender roles and happiness of couples using data from the British Household Panel Survey (BHPS) during the period 1991-2009. Various approaches are followed, including Probit-adapted fixed effects, multinomial Logit and three stage least squares. The results support that both men and women who are teleworkers spend more time on housework, while teleworking increases the probability that the household chores examined in this study, such as cooking, cleaning ironing and childcare, will be shared relatively to those who are non-teleworkers. In addition, women are happier when they or their spouse is teleworker, as well as, both men and women are happier when they state that the specific household chores are shared. Thus, teleworkers may be happier for the reason that they are able to face the family demands and share the household chores with their spouse, increasing their fairness belief about the household division allocation and improving their well-being, expressed by happiness.

description: There is an increasing concern on the quality of jobs and productivity that is witnessed in the flexible employment arrangements. However, the effects of the employment flexible types on workplace performance has not been explored in Britain. In this study the relationship between two employment arrangements and the workplace performance is examined. More specifically, teleworking and compress hours are two main employment types examined using the Workplace Employee Relations Survey (WERS) in years 2004 and 2011. The workplace

performance is measured by the financial performance and labour productivity. A positive relationship between these two types of flexible employment arrangements and workplace performance is presented. This can have various profound policy implications for employees, employers and the society overall. However, the positive association holds for employees who

have high influence on their job, while it becomes negative in the case of teleworkers who have low influence.

description: Safeguarding online communications using public key cryptography is a well-established practice today, but with the increasing reliance on `faceless', solely online entities one of the core aspects of public key cryptography is becoming a substantial problem in practice: Who can we trust to introduce us to and vouch for some online party whose public key we see for the first time? Most existing certification models lack flexibility and have come under attack repeatedly in recent years, and finding practical improvements has a high priority. We propose that the real-world concept of a notary or certifying witness can be adapted to today's online environment quite easily, and that such a system when combined with peer-to-peer technologies for defense in depth is a viable alternative to monolithic trust infrastructures. Instead of trusting assurances from a single party, integrity certifications (and data replication) can be provided among a group of independent parties in a peer-to-peer fashion. As the likelihood of all such assurance providers being subverted at the very same time is very much less than that of a single party, overall robustness is improved. This paper presents the design and the implementation of our prototype online notary system where independent computer notaries provide integrity certification and highly-available replicated storage, and discusses how this online notary system handles some common threat patterns.

description: New physics at the TeV scale is highly anticipated at the LHC. New particles with color, if within the LHC energy reach, will be copiously produced. One such particle is a diquark, having the quantum numbers of two quarks, and can be a scalar or a vector. It will decay to two light quarks, or two top quarks, or a top and a light quark, (up or down type depending on the quantum number of the produced diquark). If singly produced, it can be looked for as a dijet resonance, or as giving extra contribution to the single top production or tt production. In this work, we consider a color sextet vector diquark having the quantum number of (ud) type, its resonance production, and the subsequent decay to tb, giving rise to excess contribution to the single top production. Even though the diquark mass is large, its strong resonance production dominate the weak production of tb for a wide range of the diquark mass. Also its subsequent decay to tb produce a very hard b-jet compared to the usual electroweak production. In addition, the missing energy in the final state event is much larger from the massive diquark decays. Thus, with suitable cuts, the final state with b, bar{b} and a charged lepton together with large missing energy stands out compared to the Standard Model background. We make a detailed study of both the signal and the background. We find that such a diquark is accessible at the 7 TeV LHC upto a mass of about 3.3 TeV with the luminosity 1 fb^{-1}, while the reach goes up to about 4.3 TeV with a luminosity of 10 fb^{-1}.

description: We have observed Feshbach resonances for 133Cs atoms in two different hyperfine states at ultra-low static magnetic fields by using an atomic fountain clock. The extreme sensitivity of our setup allows for high signal-to-noise-ratio observations at densities of only 2*10^7 cm^{-3}. We have reproduced these resonances using coupled-channels calculations which are in excellent agreement with our measurements. We justify that these are s-wave resonances involving weakly-bound states of the triplet molecular Hamiltonian, identify the resonant closed channels, and explain the observed multi-peak structure. We also describe a model which precisely accounts for the collisional processes in the fountain and which explains the asymmetric shape of the observed Feshbach resonances in the regime where the kinetic energy dominates over the coupling strength.

Pseudogap temperature and effects of a harmonic trap in the BCS-BEC crossover regime of an ultracold Fermi gas

description: We theoretically investigate excitation properties in the pseudogap regime of a trapped Fermi gas. Using a combined $T$-matrix theory with the local density approximation, we calculate strong-coupling corrections to single-particle local density of states (LDOS), as well as the single-particle local spectral weight (LSW). Starting from the superfluid phase transition temperature $T_{\rm c}$, we clarify how the pseudogap structures in these quantities disappear with increasing the temperature. As in the case of a uniform Fermi gas, LDOS and LSW give different pseudogap temperatures $T^*$ and $T^{**}$ at which the pseudogap structures in these quantities completely disappear. Determining $T^*$ and $T^{**}$ over the entire BCS (Bardeen-Cooper-Schrieffer)-BEC (Bose-Einstein condensate) crossover region, we identify the pseudogap regime in the phase diagram with respect to the temperature and the interaction strength. We also show that the so-called back-bending peak recently observed in the photoemission spectra by JILA group may be explained as an effect of pseudogap phenomenon in the trap center. Since strong pairing fluctuations, spatial inhomogeneity, and finite temperatures, are important keys in considering real cold Fermi gases, our results would be useful for clarifying normal state properties of this strongly interacting Fermi system.

Terroir products and culture at the heart of the tourism industry: a qualitative study
Creators: name: Karima EL BALBAL

Publisher: name: Zenodo
Year: 2023

description: Despite health, social and economic crises, the tourism industry continues to expand and evolve, especially here in Morocco, the country that had fascinated tourists from all over the globe with its terroir products and original cultural diversity, combining amazigh, arab and african culture, in a Judeo-Muslim religious mix.
The objective of this study is to explore and understand the relationship between cultural tourism and terroir products and what impact the latter could have on internal cultural tourism. Thus, we will focus on internal cultural tourism relating to terroir products, which in our case is olive oil from the Beni-Mellal region, and more specifically from the town of Fkih Ben Saleh, known for its olive oil mills and the distinct quality of its olive oil.
We will structure our article as follows: First, we will examine the theoretical framework relating to the terroir and its products, then the conceptual framework of cultural tourism and heritage. Secondly, we will explain the research methodology and the approach followed to carry out our qualitative study and finally discuss the results obtained.

CMB Anomalies from Imperfect Dark Energy: Confrontation with the Data

description: We test anisotropic dark energy models with the 7-year WMAP temperature observations data. In the presence of imperfect sources, due to large-scale gradients or anisotropies in the dark energy field, the CMB sky will be distorted anisotropically on its way to us by the ISW effect. The signal covariance matrix then becomes nondiagonal for small multipoles, but at $\ell \gtrsim 20$ the anisotropy is negligible. We parametrize possible violations of rotational invariance in the late universe by the magnitude of a post-Friedmannian deviation from isotropy and its scale dependence. This allows to obtain hints on possible imperfect nature of dark energy and the large-angle anomalous features in the CMB. A robust statistical analysis, subjected to various tests and consistency checks, is performed to compare the predicted correlations with those obtained from the satellite-measured CMB full sky maps. The preferred axis point towards $(l,b) = (168^\circ, -31^\circ)$ and the amplitude of the anisotropy is $\varpi_0 = (0.51\pm 0.94)$ (1$σ$ deviation quoted). The best-fit model has a steep blue anisotropic spectrum ($n_{\mathrm{de}} = 3.1\pm1.5$).

Demokratische Grenzen für Völkervertragsrecht nach BVerfG III: Sind die in der Entscheidung zu CETA (BVerfGE 143, 65 ff.) zur Wahrung der verfassungsrechtlichen Grenzen formulierten Vorgaben und Mechanismen aus Sicht des Völkerrechts überzeugend?

description: In seiner Entscheidung zur vorläufigen Anwendung von CETA hat das BVerfG festgestellt, dass eine Verletzung von Verfassungsrechtsgütern möglich erscheine, sich das Risiko der verfassungsrechtlichen Nachteile jedoch durch unterschiedliche völkerrechtliche Vorkehrungen ausschließen lasse. Der vorliegende Beitrag untersucht die Vorkehrungen daraufhin, ob diese im Völkerrecht wirksam implementiert werden und aus völkerrechtlicher Sicht diejenige Wirkung entfalten können, die notwendig ist, um den mit der Vorkehrung verfolgten Zweck zu erreichen. In its decision on the provisional application of CETA, the BVerfG stated that although an infringement of constitutional rights seems possible, the risk of disadvantages could be excluded by different provisions of international law. This article examines the provisions with a view to whether they can be effectively implemented in international law and whether they can have the effect that is necessary to achieve the purpose pursued by the provision.
