description: We have studied the influence of disorder induced by electron irradiation on the normal state resistivities $ρ(T)$ of optimally and underdoped YBa2CuOx single crystals, using pulsed magnetic fields up to 60T to completely restore the normal state. We evidence that point defect disorder induces low T upturns of rho(T) which saturate in some cases at low T in large applied fields as would be expected for a Kondo-like magnetic response. Moreover the magnitude of the upturns is related to the residual resistivity, that is to the concentration of defects and/or their nanoscale morphology. These upturns are found quantitatively identical to those reported in lower Tc cuprates, which establishes the importance of disorder in these supposedly pure compounds. We therefore propose a realistic phase diagram of the cuprates, including disorder, in which the superconducting state might reach the antiferromagnetic phase in the clean limit.

Here $Z_t^1,\dots,Z_t^d$ are independent one-dimensional stable processes with $α_1,\dots,α_d\in(0,2)$. In this article we research on uniqueness of weak solutions to such systems by studying the corresponding martingale problem. We prove the uniqueness of weak solutions in the case of diagonal coefficient matrices.

The importance of shift work: The hospitality sector

description: This study explores the importance of shift work in the organizational context of the hospitality sector. To answer the three research objectives (1) to characterize individual motivations for working shift work; (2) to identify the degree of satisfaction with the shift work regime and; (3) to understand the impact of shift work on the worker's physical, mental, social well-being and family environment, a survey was developed and published online to sample of 154 shift workers in the hospitality sector. The results indicate that the main motivation to work in shifts is related to the requirement of the function they perform. The degree of satisfaction of workers in shift work tends to decrease when they evaluate satisfaction with the balance between work life and the other dimensions - personal, family and social life. Most respondents say that if they could choose, they would not choose to work in shifts, considering the negative effects on their physical and mental well-being and family and social well-being. From the results obtained, we contribute to the literature on shift work by showing the need for greater organizational support, be it at the level of physical conditions of work or at the level of benefits promoting social well-being of this category of workers.

description: Matters falling into and consisting of a blackhole can oscillate periodically across instead of accumulate statically on the central point and form singularities there. In quantum language, this oscillation not only resolves central singularities of the blackhole but also blurs its horizon remarkably. This blurring makes the horizon not a zero-thickness geometric surface any more, but an extended physic region whose thickness is comparable with the horizon radius itself. It is our negligence of this fact that leads to the information missing puzzle, and other related question in blackhole physics. Besides the title question and Schwarzschild singularity's resolving, the current work also provides interpretations for the origin of Bekenstein-Hawking entropy and an explicitly unitary formulation of Hawking radiations.

description: We propose and demonstrate the sequential initialization, optical control, and read-out of a single spin trapped in a semiconductor quantum dot. Hole spin preparation is achieved through ionization of a resonantly excited electron-hole pair. Optical control is observed as a coherent Rabi rotation between the hole and charged exciton states, which is conditional on the initial hole spin state. The spin-selective creation of the charged exciton provides a photocurrent read-out of the hole spin state.

description: Significant efforts have been and are being spent on developing intensified tubular reactors for continuous manufacturing of fine and specialty chemicals. In this work, we have proposed a new design of passive mixer-cum-reactor for process intensification and development of continuous processes. The mixer/reactor consists of threaded inserts with cone-shaped ends, placed concentrically in the tube such that fluid flows through the annular region between the inserts and the tube. The proposed design is easy to fabricate, maintain, and overcomes the limitations of scale up/scale down compared to most of the commercial passive mixers. The split and recombine of flow around inserts, the swirling effect generated by threads, change in the swirl direction due to change in the direction of screw threads, and pinching effect/expansion at the cone-cone shaped ends realize desired enhancements in mixing and heat transfer. A detailed computational study has been carried out on the mixer-cum-reactor to characterize flow, mixing and heat transfer at different operating conditions using a verified and validated CFD model. Various designs and configurations of threaded inserts were considered: 5-channel, 7-channel and 9-channel, smooth surface (no threading) and smooth surface-extended rear end inserts. The flow, mixing and heat transfer were characterized over the Reynolds number range of 100 to 1600. Structure of the generated swirling flow, effect of pinching/expansion, direction reversal of flow, tracer fraction, temperature and path lines were investigated systematically to gain new insights. Threaded inserts could achieve excellent mixing (>99 % of mixing intensity) and heat transfer (7 times smooth inserts and 20 times without inserts). The presented results will provide a sound basis for selecting appropriate threaded inserts for intensifying mixing and heat transfer in tubular reactors. The work also provides a useful starting point for further work on multiphase flows in a tubular reactor with threaded inserts.

description: Objective: To evaluate patient satisfaction and patient and physician assessment of scar appearance after cesarean skin closure with suture versus staples. Methods: Women undergoing cesarean delivery (CD) at ≥23 weeks’ gestation via low-transverse skin incisions at three hospitals in the CROSS Consortium were randomized to receive skin closure using subcuticular absorbable suture or nonabsorbable metal staples. The primary outcome of this substudy, patient satisfaction, was assessed by surveys at the postpartum visit using a 10-point Likert scale. Scar outcomes according to patients and trained observers were assessed at the primary research site using the Patient and Observer Scar Assessment Scale (POSAS). The POSAS is comprised of a patient-completed assessment including subjective data such as pain and itchiness, and an observer-completed assessment about cosmetic criteria. Results: Between June 2010 and August 2012, 746 women were randomized; 370 received suture and 376 received staples. Satisfaction data were available for 606 (81%). Complete patient scar assessment data were available for 577 (77%) and complete observer scar assessment data were available for 275 (57% of the 480 planned for evaluation at the primary research site). Demographic data for women in the two groups were similar. Satisfaction with the closure method was higher (superior) among women who received suture closure: median 10 (interquartile range 9, 10) versus 9 (interquartile ranges (IQR) 6, 10); p p = .02. Receiving one’s preferred closure method was associated with higher patient satisfaction, and wound complications were associated with lower satisfaction. POSAS scores were superior (lower) in the suture group. Patient Scar Assessment Scale scores were median 15 (IQR 10, 25) for sutures versus 20 (IQR 11, 28) for staples; p p = .01. Conclusions: Satisfaction with the closure method, satisfaction with the scar’s appearance, and patient and physician assessments of scar cosmesis were all superior in those closed with suture. These results further support the use of sutures for cesarean skin closure. Trial registration:ClinicalTrials.gov identifier: NCT01211600.

description: Nowadays, tourism plays a very important role in the growth of the economy, and in particular, in the province of Burgos the tourism sector is an important source of economic and social development. Therefore, it is necessary to optimize the competitive advantages of this area of northern Spain by creating a responsible and sustainable tourism model that aims to reach the 17 SDGs. This study analyses the evolution of tourist supply and demand, comparing it with data from Castilla y León, Spain and five other provinces in Spain, as well as examining the tourist's profile and perception. The findings show that the increase in the number of hotel establishments was greater than that at national and regional level, but the growth of the supply of rural tourism accommodation establishments has stagnated in the last two years. The number of passengers in Burgos has been growing since 2012, with a slight decrease in 2018, in contrast the number of travellers in rural accommodation establishments has increased substantially since 2015. The visits are characterized by being short and with few expenses, focused mainly on the restoration. The degree of overall satisfaction and loyalty continues to be high. Finally, all services related to catering, infrastructures, information points and complementary activities to historical tourism should be improved to maximize tourist satisfaction and loyalty.

description: Ejection activities in S255IR-SMA1 and AFGL 5142 were investigated by multi-epoch VLBI observations of 22 GHz water masers, tracing bowshocks leading collimated jets. The history of ejections, revealed by the 3D maser motions and supplemented by the literature, suggests that these massive stars formed by episodic accretion, inferred via the accretion-ejection connection. This contribution centers on the role of episodic accretion in overcoming the radiation pressure problem of massive star formation - with maser VLBI and single-dish observations providing essential observational tools.

description: We study the mod $2$ cohomology of real Calabi-Yau threefolds given by real structures which preserve the torus fibrations constructed by Gross. We extend the results of Castaño-Bernard-Matessi and Arguz-Prince to the case of real structures twisted by a Lagrangian section. In particular we find exact sequences linking the cohomology of the real Calabi-Yau with the cohomology of the complex one. Applying SYZ mirror symmetry, we show that the connecting homomorphism is determined by a ``twisted squaring of divisors'' in the mirror Calabi-Yau, i.e. by $D \mapsto D^2 + DL$ where $D$ is a divisor in the mirror and $L$ is the divisor mirror to the twisting section. We use this to find an example of a connected $(M-2)$-real quintic threefold.

description: This article aims to present reflections on the integration of sustainability principles in tourism, in rural communities. In these regions, several elements attract the contemporary tourist, such as the authenticity of the culture, being of particular importance the involvement of the residents, as a key factor for the emancipation of the community and for local development. In this context, the question "How can a rural community emancipate itself through tourism? The research presents as a case study a village in Portugal, Podence, which is characterized by the socio-economic dynamization of its intangible cultural heritage, distinguished by UNESCO. Following a qualitative approach, the method of participant observation and semi-structured interviews was applied to understand the local perspective on tourism development. The results show the positive contribution of tourism activity to the community, through cultural enhancement and by the dynamization of the local economy. The importance of the cultural legacy for the well-being of the population, contributing to its sense of belonging, is notorious.

We prove that the inequivalent connectivities of the N=5 and N=9 irreducible supermultiplets are due to inequivalent decompositions into two sets of N=4 (respectively, N=8) supermultiplets. "Oxido-reduction" diagrams linking the irreducible supermultiplets of the N=5,6,7,8 supersymmetries are presented. We briefly discuss these results and their possible applications.

description: N44 is the second active site of high mass star formation next to R136 in the Large Magellanic Cloud (LMC). We carried out a detailed analysis of HI at 60 arcsec resolution by using the ATCA & Parkes data. We presented decomposition of the HI emission into two velocity components (the L- and D-components) with the velocity separation of 60 km s$^{-1}$. In addition, we newly defined the I-component whose velocity is intermediate between the L- and D-components. The D-component was used to derive the rotation curve of the LMC disk, which is consistent with the stellar rotation curve (Alves et al. 2000). Toward the active cluster forming region of LHA 120-N 44, the three velocity components of HI gas show signatures of dynamical interaction including bridges and complementary spatial distributions. We hypothesize that the L- and D-components have been colliding with each other since 5 Myrs ago and the interaction triggered formation of the O and early B stars ionizing N44. In the hypothesis the I-component is interpreted as decelerated gas in terms of momentum exchange in the collisional interaction of the L- and D-components. In the N44 region the Planck sub-mm dust optical depth is correlated with the HI intensity, which is well approximated by a linear regression. We found that the N44 region shows a significantly steeper regression line than in the Bar region indicating less dust abundance in the N44 region, which is ascribed to the tidal interaction between the LMC with the SMC 0.2 Gyrs ago.

description: Uromycladium acaciae is the cause of a severe wattle rust epidemic in plantations of Acacia mearnsii (black wattle) in southern Africa. Research on the biology of this damaging rust is assisting in the development of control strategies. One strategy under investigation is the identification and deployment of resistant lines of A. mearnsii. Selection of resistant families currently relies on large-scale, time-consuming and expensive field trials. In this study, we present a detailed artificial inoculation protocol for U. acaciae, which can be used to screen for resistance. The results of an experiment that used the protocol to screen the relative resistance of 12 families of A. mearnsii to U. acaciae are also presented. The developed artificial inoculation protocol can also be used to investigate several other aspects of this host–pathogen system.

description: Transition metal dichalcogenides (TMDCs) combine both strong light-matter-interaction and strong Coulomb-interaction for the formation of optically excitable excitons. Through radiative feedback control, a mechanism to control the linewidth can be applied, which modifies optical transition spectra. Here, we extend these investigations to the absorption spectra of TMDCs in a variety of geometries with respect to non-Markovian exciton-phonon-scattering contributions. Our approach is based on the self consistent solution of the microscopic Bloch equations and the macroscopic solution of the wave equation. We discuss the formation of a phonon sideband for MoSe$_2$ embedded in SiO$_2$, and two setups for enhancing or suppressing the phonon sideband in the spectrum.

description: A spectral line survey of IRC +10216 between 13.3 and 18.5 GHz is carried out using the Shanghai Tian Ma 65 m Radio Telescope (TMRT-65m) with a sensitivity of < 7 mK. Thirty-five spectral lines of 12 different molecules and radicals are detected in total. Except for SiS, the detected molecules are all carbon-chain molecules, including HC3N, HC5N, HC7N, HC9N, C6H, C6H-, C8H, SiC2, SiC4, c-C3H2 and l-C5H. The presence of rich carbon-bearing molecules is consistent with the identity of IRC +10216 as a carbon-rich AGB star. The excitation temperatures and column densities of the observed species are derived by assuming a local thermodynamic equilibrium and homogeneous conditions.

Maximizing the potential of river sports to boost sustainable tourism development: Identification of the determinants of tourist consumption associated with river sports
Creators: name: Ferreira, Maria João

Publisher: name: Journal of Tourism & Development
Year: 2021

description: Tourism has important economic impacts, but these are concentrated particularly on areas such as the coast. River sports such as kayaking and canoeing, in addition to having very low negative environmental impacts, can extend positive economic impacts to geographical areas beyond the coastlines. Understanding the factors that influence expenditures on river sports is critical to maximize the economic impacts of these sports as well as their potential to boost sustainable tourism development. Despite the growing research on sports tourism consumption and its determinants, it mainly focuses on sport events and certain sports. No study was found on the factors that influence tourism consumption in river sports. The aim of this paper is to analyse the consumption patterns of visitors related to river sports and the factors that determine this consumption. A questionnaire survey was conducted in Portugal, which permitted the conclusion that the surveyed river sports practitioners tend to spend more on accommodation, catering and retail and that the factors that positively influence consumption are, above all, income and some characteristics of the trip. The paper ends with conclusions and implications for tourism sector agents

description: This paper examines the role of Social Studies in the teaching of morals to minimize the prevalence of moral degeneration in contemporary Nigerian society. The causes and consequences of moral degeneration in society were examined. The paper employed the descriptive survey research design and Social Learning Theory to explain that individuals tend to act based on their observations in society. The paper made use of both primary (questionnaire) and secondary (books, journals, and online materials) types of data. The paper was guided by three research questions. The findings revealed that social studies being a value and moral-laden subject can help minimize moral degeneration's prevalence in contemporary Nigerian society. It is recommended that there should be a national re-orientation of national values among Nigerians by Nigeria's federal, state, and local governments
Masses for the Local Group and the Milky Way

description: We use the very large Millennium Simulation of the concordance $Λ$CDM cosmogony to calibrate the bias and error distribution of Timing Argument estimators of the masses of the Local Group and of the Milky Way. From a large number of isolated spiral-spiral pairs similar to the Milky Way/Andromeda system, we find the interquartile range of the ratio of timing mass to true mass to be a factor of 1.8, while the 5% and 95% points of the distribution of this ratio are separated by a factor of 5.7. Here we define true mass as the sum of the ``virial'' masses $M_{200}$ of the two dominant galaxies. For current best values of the distance and approach velocity of Andromeda this leads to a median likelihood estimate of the true mass of the Local Group of $5.27\times 10^{12}\msun$, or $\log M_{LG}/M_\odot = 12.72$, with an interquartile range of $[12.58, 12.83]$ and a 5% to 95% range of $[12.26, 13.01]$. Thus a 95% lower confidence limit on the true mass of the Local Group is $1.81\times 10^{12}\msun$. A timing estimate of the Milky Way's mass based on the large recession velocity observed for the distant satellite Leo I works equally well, although with larger systematic uncertainties. It gives an estimated virial mass for the Milky Way of $2.43 \times 10^{12}\msun$ with a 95% lower confidence limit of $0.80 \times 10^{12}\msun$.

description: A foundational principle in the study of modules over standard graded polynomial rings is that geometric positivity conditions imply vanishing of Betti numbers. The main goal of this paper is to determine the extent to which this principle extends to the nonstandard graded case. In this setting, the classical arguments break down, and the results become much more nuanced. We introduce a new notion of Castelnuovo-Mumford regularity and employ exterior algebra techniques to control the shapes of nonstandard graded minimal free resolutions. Our main result reveals a unique feature in the nonstandard graded case: the possible degrees of the syzygies of a graded module in this setting are controlled not only by its regularity, but also by its depth. As an application of our main result, we show that, given a simplicial projective toric variety and a module M over its coordinate ring, the multigraded Betti numbers of M are contained in a particular polytope when M satisfies an appropriate positivity condition.

description: We develop the theory of quantum (a.k.a. noncommutative) relations and quantum (a.k.a. noncommutative) graphs in the finite-dimensional covariant setting, where all systems (finite-dimensional $C^*$-algebras) carry an action of a compact quantum group $G$, and all channels (completely positive maps preserving the canonical $G$-invariant state) are covariant with respect to the $G$-actions. We motivate our definitions by applications to zero-error quantum communication theory with a symmetry constraint. Some key results are the following: 1) We give a necessary and sufficient condition for a covariant quantum relation to be the underlying relation of a covariant channel. 2) We show that every quantum confusability graph with a $G$-action (which we call a quantum $G$-graph) arises as the confusability graph of a covariant channel. 3) We show that a covariant channel is reversible precisely when its confusability $G$-graph is discrete. 4) When $G$ is quasitriangular (this includes all compact groups), we show that covariant zero-error source-channel coding schemes are classified by covariant homomorphisms between confusability $G$-graphs.

description: We present a simple thermodynamically consistent method for solving time-dependent Fokker--Planck equations (FPE) for over-damped stochastic processes, also known as Smoluchowski equations. It yields both transition and steady-state behavior and allows for computations of moment-generating and large-deviation functions of observables defined along stochastic trajectories, such as the fluctuating particle current, heat and work. The key strategy is to approximate the FPE by a Master equation with transition rates in configuration space that obey a local detailed balance condition for arbitrary discretization. Its time-dependent solution is obtained by a direct computation of the time-ordered exponential, representing the propagator of the FPE, by summing over all possible paths in the discretized space. The method thus not only preserves positivity and normalization of the solutions, but also yields a physically reasonable total entropy production, regardless of the discretization. To demonstrate the validity of the method and to exemplify its potential for applications, we compare it against Brownian-dynamics simulations of a heat engine based on an active Brownian particle trapped in a time-dependent quartic potential.

description: For an arbitrary convex quadrilateral $ABCD$ with area ${\cal A}$ and perimeter $p$, we define two points $I_1, I_2$ on its Newton line that serve as incenters. These points are the centers of two circles with radii $r_1, r_2$ that are tangent to opposite sides of $ABCD$. We then prove that ${\cal A}=pr/2$, where $r$ is the harmonic mean of $r_1$ and $r_2$. We also investigate the special cases with $I_1\equiv I_2$ and/or $r_1=r_2$.

description: Within tourism, the marketing studies seek to explain the tourist behavior and one of the most explored variables has been emotion. The evaluation of emotions is an element of multidisciplinary interest applied to different areas of research. Starting from the study of the psychological models and theories applied to tourism marketing as a theoretical support, the objective of this work is to focus the definition and possible conceptualization of emotions in the study of typical marketing variables such as satisfaction and behavior. The results show the need to include a psychological approach to the theoretical framework of the study of emotions in tourism, since it helps to conceptualize and foresee reactions and the design of theoretical models and new inputs for experimentation.

description: The coupling of microwave and optical systems presents an immense challenge due to the natural incompatibility of energies, but potential applications range from optical interconnects for quantum computers to next-generation quantum microwave sensors, detectors or coherent imagers. Several engineered platforms have emerged that are constrained by specific conditions, such as cryogenic environments, impulse protocols, or narrowband fields. Here we employ Rydberg atoms that allow for the natural wideband coupling of optical and microwave photons even at room temperature and with the use of a modest setup. We present continuous-wave conversion of a $13.9\ \mathrm{GHz}$ field to a near-infrared optical signal using an ensemble of Rydberg atoms via a free-space six-wave mixing process, designed to minimize noise interference from any nearby frequencies. The Rydberg photonic converter exhibits an unprecedented conversion dynamic range of $57\ \mathrm{dB}$ and a wide conversion bandwidth of $16\ \mathrm{MHz}$. Using photon counting, we demonstrate the readout of photons of free-space $300\ \mathrm{K}$ thermal background radiation at $1.59\ \mathrm{nV}\mathrm{cm}^{-1}(\mathrm{rad}/\mathrm{s})^{-1/2}$ ($3.98 \ \mathrm{nV}\mathrm{cm}^{-1}\mathrm{Hz}^{-1/2}$) with the sensitivity down to $3.8\ \mathrm{K}$ of noise-equivalent temperature, allowing us to observe Hanbury Brown and Twiss interference of microwave photons.

description: Objective: Metabolic disorders are a pandemic and increasing health problem. Women of childbearing age may also be affected, thus an abnormal metabolism may interfere with pregnancy short- and long-term outcomes, harming both mother and child. In the context of an abnormal maternal and intrauterine metabolic milieu the development of fetal organs, including pancreas, may be affected. Aim: To investigate the effects of pregnancy metabolic disorders on the morphology of pancreatic Langerhans islets in human late-third trimester stillborn fetuses. Methods: Samples from fetal pancreas underwent a quantitative histological evaluation to detect differences between pregnancy with (cases, n = 9) or without (controls, n = 6) abnormal metabolism. Results: Results show that the islets size increases in fetuses from dysmetabolic pregnancies and that this increment is related to both beta-cell hyperplasia and hypertrophy. Moreover, according to pregnancy and fetal metabolic disorders, a threshold of abnormal size of the islets has been identified. Above this threshold the size of fetal pancreatic Langerhans islets should be considered excessively increased. Conclusion: The study suggests that an accurate fetal pancreas analysis supplies an important tool in stillborn fetus, to discover metabolic disturbances that should be kept in mind and managed in future pregnancies.
Band Topology and Linking Structure of Nodal Line Semimetals with Z2 Monopole Charges

description: We study the band topology and the associated linking structure of topological semimetals with nodal lines carrying $Z_{2}$ monopole charges, which can be realized in three-dimensional systems invariant under the combination of inversion $P$ and time reversal $T$ when spin-orbit coupling is negligible. In contrast to the well-known $PT$-symmetric nodal lines protected only by $π$ Berry phase in which a single nodal line can exist, the nodal lines with $Z_{2}$ monopole charges should always exist in pairs. We show that a pair of nodal lines with $Z_{2}$ monopole charges is created by a {\it double band inversion} (DBI) process, and that the resulting nodal lines are always {\it linked by another nodal line} formed between the two topmost occupied bands. It is shown that both the linking structure and the $Z_{2}$ monopole charge are the manifestation of the nontrivial band topology characterized by the {\it second Stiefel-Whitney class}, which can be read off from the Wilson loop spectrum. We show that the second Stiefel-Whitney class can serve as a well-defined topological invariant of a $PT$-invariant two-dimensional (2D) insulator in the absence of Berry phase. Based on this, we propose that pair creation and annihilation of nodal lines with $Z_{2}$ monopole charges can mediate a topological phase transition between a normal insulator and a three-dimensional weak Stiefel-Whitney insulator (3D weak SWI). Moreover, using first-principles calculations, we predict ABC-stacked graphdiyne as a nodal line semimetal (NLSM) with $Z_{2}$ monopole charges having the linking structure. Finally, we develop a formula for computing the second Stiefel-Whitney class based on parity eigenvalues at inversion invariant momenta, which is used to prove the quantized bulk magnetoelectric response of NLSMs with $Z_2$ monopole charges under a $T$-breaking perturbation.
