description: We construct Poisson structures for Ermakov systems, using the Ermakov invariant as the Hamiltonian. Two classes of Poisson structures are obtained, one of them degenerate, in which case we derive the Casimir functions. In some situations, the existence of Casimir functions can give rise to superintegrable Ermakov systems. Finally, we characterize the cases where linearization of the equations of motion is possible.

description: Musculoskeletal problems (MSD) influence the staffs in numerous professions including vehicle drivers. The examinations happening muscular issues from truck, taxi, and bus drivers were attempted yet there is no investigation to assess these three automobile users and give ergonomic interferences amongst them. In such manner, the study means to survey the level of musculoskeletal problems on critical elements influencing the three automobiles as for demographic contours and undertakings drivers’ appliance. It additionally means to evaluate the degree of musculoskeletal sufferings of physical portions of automobile drivers from the usual factors, and suggest ergonomic facilitations to address frequency of musculoskeletal problems among the drivers. Evaluation on the issues of these vehicle drivers utilizing RULA and CMDQ were attempted. The outcomes exhibited that there was a correlation on the body portions of truck, taxi and bus drivers on the RULA and CMDQ esteems. The vehicle drivers showed that their neck, inferior back, subordinate legs, upper limb and wrists were the main five greatest usual body parts associated with musculoskeletal issues. As such, the study proposes proposed ergonomics interferences required for these body portions.

description: In 2011-2012 sugarcane yields in the Brazilian south-central region fell 15 percent lower than the average of the previous decade. This corresponded to the end of a decade of uninterrupted growth in sugarcane ethanol production in Brazil. Several explanations for this fall have been proposed including inclement weather, and a low field renewal rate due to the 2008-2009 financial crisis. We gather academic and journalistic evidence to demonstrate the possiblity of the crisis-renewal pathway. We develop a theoretical model of perennial crop yields as a function of the renewal rate. We theoretically derive the number of lags of the renewal rate that should be used in a reduced form specification of perennial crop yields. Using a balanced panel of yields and renewal rates in the South-Central region of Brazil from 2005-2013 we investigate the relevance of these pathways. We find that the yield effects from a renewal rate change in Brazil are consistent with the yield effects predicted by our model. We also find that both pathways are significant, but that the weather pathway is driven by temperature, not rainfall.

description: The superconformal structure of coset superspaces with AdS_m x S^n geometry of bosonic subspaces is studied. It is shown, in particular, that the conventional superspace extensions of the coset manifolds AdS_2 x S^2, AdS_3 x S^3 and AdS_5 x S^5, which arise as solutions of corresponding D=4,6, 10 supergravities and have been extensively studied in connection with AdS/CFT correspondence, are not superconformally flat, though their bosonic submanifolds are conformally flat. We give a group-theoretical reasoning for this fact. We find that in the AdS_2 x S^2 and AdS_3 x S^3 cases there exist different supercosets based on the supergroup OSp(4^*|2) which are superconformally flat. We also argue that in D=2,3,4 and 5 there exist superconformally flat `pure' AdS_D supercosets. Two methods of checking the superconformal flatness are proposed. One of them consists in solving the Maurer-Cartan structure equations and the other is based on embedding the isometry supergroup of the AdS_m x S^n superspace into a superconformal group in (m+n)-dimensional Minkowski space. Finally, we discuss some applications of the above results to the description of supersymmetric dynamical systems.

description: Abstract: We introduce a general technique for proving estimates for certain random planar maps which belong to the γ-Liouville quantum gravity (LQG) universality class for γ∈(0, 2). The family of random planar maps we consider are those which can be encoded by a two-dimensional random walk with i.i.d. increments via a mating-of-trees bijection, and includes the uniform infinite planar triangulation (UIPT; γ=8/3); and planar maps weighted by the number of different spanning trees (γ=2), bipolar orientations (γ=4/3), or Schnyder woods (γ=1) that can be put on the map. Using our technique, we prove estimates for graph distances in the above family of random planar maps. In particular, we obtain non-trivial upper and lower bounds for the cardinality of a graph distance ball consistent with the Watabiki (Prog Theor Phys Suppl 114:1–17, 1993) prediction for the Hausdorff dimension of γ-LQG and we establish the existence of an exponent for certain distances in the map. The basic idea of our approach is to compare a given random planar map M to a mated-CRT map—a random planar map constructed from a correlated two-dimensional Brownian motion—using a strong coupling (Zaitsev in ESAIM Probab Stat 2:41–108, 1998) of the encoding walk for M and the Brownian motion used to construct the mated-CRT map. This allows us to deduce estimates for graph distances in M from the estimates for graph distances in the mated-CRT map which we proved (using continuum theory) in a previous work. In the special case when γ=8/3, we instead deduce estimates for the 8/3-mated-CRT map from known results for the UIPT. The arguments of this paper do not directly use SLE/LQG, and can be read without any knowledge of these objects.

description: The boson-conserving one-nucleon transfer operator in the interacting boson model (IBA) is reanalyzed. Extra terms are added to the usual form used for that operator. These new terms change generalized seniority by one unit, as the ones considered up to now. The results obtained using the new form for the transfer operator are compared with those obtained with the traditional form in a simple case involving the pseudo-spin Bose-Fermi symmetry $U^{B}(6) \otimes U^F(12)$ in its $U^{BF}(5) \otimes U^F(2)$ limit. Sizeable differences are found. These results are of relevance in the study of transfer reactions to check nuclear supersymmetry and in the description of (β)-decay within IBA.

description: The Standard Model (SM) with a light Higgs boson provides a very good description of the precision electroweak observable data coming from the LEP, SLD and Tevatron experiments. Most of the observables, with the notable exception of the forward-backward asymmetry of the bottom quark, point towards a Higgs mass far below its current experimental bound. The disagreement, within the SM, between the values for the weak mixing angle as obtained from the measurement of the leptonic and hadronic asymmetries at lepton colliders, may be taken to indicate new physics contributions to the precision electroweak observables. In this article we investigate the possibility that the inclusion of additional bottom-like quarks could help resolve this discrepancy. Two inequivalent assignments for these new quarks are analysed. The resultant fits to the electroweak data show a significant improvement when compared to that obtained in the SM. While in one of the examples analyzed, the exotic quarks are predicted to be light, with masses below 300 GeV, and the Higgs tends to be heavy, in the second one the Higgs is predicted to be light, with a mass below 250 GeV, while the quarks tend to be heavy, with masses of about 800 GeV. The collider signatures associated with the new exotic quarks, as well as the question of unification of couplings within these models and a possible cosmological implication of the new physical degrees of freedom at the weak scale are also discussed.

description: We find the Lie point symmetries for non-relativistic two-dimensional charged particle motion. These symmetries comprise a quasi-invariance transformation, a time-dependent rotation, a time-dependent spatial translation and a dilation. The associated electromagnetic fields satisfy a system of first-order linear partial differential equations. This system is solved exactly, yielding four classes of electromagnetic fields compatible with Lie point symmetries.

description: Steel marine structures provide foci of biodiversity when they develop into artificial reefs. Development begins with deposition of a biofilm. The effects of contaminants from oil spills on biofilm microbiomes, microbially-induced corrosion (MIC) and metal loss may impact preservation of marine metal structures. A microcosm experiment exposed biofilms on carbon steel disks (CSDs) to crude oil, dispersant, and dispersed oil to address their impacts on bacterial composition and metal loss and pitting. Biofilm diversity increased over time in all exposures. Community composition in dispersant and dispersed oil treatments deviated from the controls for the duration of a 12-week experiment. As biofilms matured, Pseudomonadaceae increased while Rhodobacteraceae decreased in abundance in dispersed oil treatments compared to the controls and dispersant treatments. Greatest mass loss and deepest pitting on CSDs were observed in dispersed oil treatments, suggesting impacts manifest as a consequence of increased MIC potential on carbon steel.

description: Carbon materials doped with nitrogen have long been used for SO2 removal from flue gases for the benefits of the environment. The role of water is generally regarded as hydration of SO3 which is formed through the oxidization of SO2. However, the hydration of SO2, especially on the surface of N doped carbon materials, was almost ignored. In this study, the hydration of SO2 was investigated in detail on the pyridinic nitrogen (PyN) doped graphene (GP) surfaces. It is found that, compared to the homogeneous hydration of SO2 assisted with NH3 in gas phase, the heterogeneous hydration is much more thermodynamically and kinetically favourable. Specifically, when a single H2O molecule is involved, the energy barrier for SO2 hydration is as low as 0.15 eV, with 0.59 eV released, indicating the hydration of SO2 can occur at rather low water concentration and temperature. Thermodynamic integration molecular dynamics results show the feasibility of the hydrogenated substrate recovery and the immobilized N acting as a catalytic site for SO2 hydration. Our findings show that the heterogeneous hydration of SO2 should be universal and potentially uncover the puzzling reaction mechanism for SO2 catalytic oxidation at low temperature by N doped carbon materials.

description: In this study, new smart zinc oxide (ZnO) and magnetic (Fe3O4) nanocarrier based on microcrystalline cellulose with functional cationic groups were developed by the combination of the grafting-onto method and reversible addition fragmentation chain transfer polymerization method. The synthesized nanocarriers were step by step validated and characterized using 1H NMR, FTIR, VSM, TGA, DLS, and SEM-EDX analysis. The resulting NCs were uniform spherical NCs with a mean diameter of less than 70 nm. Methotrexate (MTX) was selectively attached to nanocarrier by ionic interaction with cationic part of nanoparticles and complexing with inorganic metal oxide part of NCs (high encapsulation efficiency of >98%). This NC–MTX conjugated system was used for targeted therapy of breast cancer cell line (MCF7). The cytotoxicity studies revealed high antitumor efficacy of MTX-ZnO NCs compared to MTX-Fe3O4 NCs and free MTX in MCF7 breast cancer cell lines due to high interaction of ZnO with MTX proved by DAPI staining and MTT assay. The formation of the complexes between the MTX and ZnO nanoparticles, lead to more sustainer drug release and enhanced chemotherapy efficiency by increasing the intracellular concentration of MTX.

description: The non-renormalization theorem of chiral vertices and the generalized non-renormalization theorem of the photon self energy are derived in SQED on the basis of algebraic renormalization. For this purpose the gauge coupling is extended to an external superfield. This extension already provides detailed insight into the divergence structure. Moreover, using the local supercoupling together with an additional external vector multiplet that couples to the axial current, the model becomes complete in the sense of multiplicative renormalization, with two important implications. First, a Slavnov--Taylor identity describing supersymmetry, gauge symmetry, and axial symmetry including the axial anomaly can be established to all orders. Second, from this Slavnov-Taylor identity we can infer a Callan-Symanzik equation expressing all aspects of the non-renormalization theorems. In particular, the gauge $β$-function appears explicitely in the closed form.

description: Abstract: Background: Chondroitin sulfate proteoglycans (CSPGs) are potent inhibitors of axonal regrowth and remyelination. More recently, they have also been highlighted as a modulator of macrophage infiltration into the central nervous system in experimental autoimmune encephalomyelitis, an inflammatory model of multiple sclerosis. Methods: We interrogated results from single nucleotide polymorphisms (SNPs) lying in or close to genes regulating CSPG metabolism in the summary results from two publicly available systematic studies of multiple sclerosis (MS) genetics. A demyelinating injury model in the spinal cord of exostosin-like 2 deficient (EXTL2-/-) mice was used to investigate the effects of dysregulation of EXTL2 on remyelination. Cell cultures of bone marrow-derived macrophages and primary oligodendrocyte precursor cells and neurons were supplemented with purified CSPGs or conditioned media to assess potential mechanisms of action. Results: The strongest evidence for genetic association was seen for SNPs mapping to the region containing the glycosyltransferase exostosin-like 2 (EXTL2), an enzyme that normally suppresses CSPG biosynthesis. Six of these SNPs showed genome-wide significant evidence for association in one of the studies with concordant and nominally significant effects in the second study. We then went on to show that a demyelinating injury to the spinal cord of EXTL2−/− mice resulted in excessive deposition of CSPGs in the lesion area. EXTL2−/− mice had exacerbated axonal damage and myelin disruption relative to wild-type mice, and increased representation of microglia/macrophages within lesions. In tissue culture, activated bone marrow-derived macrophages from EXTL2−/− mice overproduce tumor necrosis factor α (TNFα) and matrix metalloproteinases (MMPs). Conclusions: These results emphasize CSPGs as a prominent modulator of neuroinflammation and they highlight CSPGs accumulating in lesions in promoting axonal injury.

description: It is currently believed that the local causality of Quantum Field Theory (QFT) is destroyed by the measurement process. This belief is also based on the Einstein-Podolsky-Rosen (EPR) paradox and on the so-called Bell's theorem, that are thought to prove the existence of a mysterious, instantaneous action between distant measurements. However, I have shown recently that the EPR argument is removed, in an interpretation-independent way, by taking into account the fact that the Standard Model of Particle Physics prevents the production of entangled states with a definite number of particles. This result is used here to argue in favor of a statistical interpretation of QFT and to show that it allows for a full reconciliation with locality and causality. Within such an interpretation, as Ballentine and Jarret pointed out long ago, Bell's theorem does not demonstrate any nonlocality.

description: Although Artificial Intelligence (AI) holds immense potential to enhance the educational experience, its use also presents challenges. This research examines the use and misuse of AI tools for university-related tasks. We surveyed 498 students from three faculties at a large European university to, first, identify factors driving their willingness to use AI tools for university-related tasks, and, second, estimate the prevalence of cheating behavior involving the unauthorized use of AI tools in examinations. Specifically, we tested and extended the Technology Acceptance Model 2 (TAM2) by identifying trust and perceived opportunity costs as additional determinants of using AI tools for university-related tasks. To estimate the proportion of students cheating during examinations, we applied a randomized response technique. We discuss the results with respect to the effective and appropriate implementation of AI tools in higher education. Our findings can help educators and policymakers to promote responsible AI use while mitigating its misuse.

description: Using an extended version of the Nambu-Jona-Lasinio model we build a simple description of the baryons as diquark-quark bound states. First, a description of the diquarks in a dense and hot medium is presented. Then, we introduce the formalism for the baryons based on the Faddeev equation associated with the so-called `` static approximation'' which finally gives a Bethe-Salpeter equation in the diquarks-quarks channel. By identifying the baryons with the bound states, we can obtain a description of their properties. In particular, we obtain the right mass spectrum for the proton, $Λ$, $Ξ$, and $Σ$ at T=0 and $μ=0$. We extend the formalism to finite temperature and density to obtain a description of the mass change of these baryons in the medium.

description: Light-matter interactions at the single particle level have generally been explored in the context of atomic, molecular, and optical physics. Recent advances motivated by quantum information science have made it possible to explore coherent interactions between photons trapped in superconducting cavities and superconducting qubits. Spins in semiconductors can have exceptionally long spin coherence times and can be isolated in silicon, the workhorse material of the semiconductor microelectronic industry. Here, we review recent advances in hybrid "super-semi" quantum systems that coherently couple superconducting cavities to semiconductor quantum dots. We first present an overview of the underlying physics that governs the behavior of superconducting cavities, semiconductor quantum dots, and their modes of interaction. We then survey experimental progress in the field, focusing on recent demonstrations of cavity quantum electrodynamics in the strong coupling regime with a single charge and a single spin. Finally, we broadly discuss promising avenues of future research.

 Leucothoe micronesiae J.L. Barnard, 1965: 490–492, fig. 6. — Ledoyer, 1978a: 299. — Ledoyer,1979a: 107, fig. 65. — Ledoyer, 1986: 667–670, fig. 256. — Ortiz & Lalana, 1997: 108.
 Type locality and specimens. Ifaluk Atoll, Caroline Islands. Holotype, female, 2.5 mm, USNM 106805.
 Material examined. No material available for examination. Diagnosis based on description by J. L. Barnard (1965).
 Diagnosis (female). Gnathopod 1 basis anteroproximally expanded; propodus narrowing distally; dactylus very short. Gnathopod 2 basis distally expanded; carpus distally truncate; propodus palm concave with three to four major tubercles. Pereopods 5–7 bases narrowly expanded.
 Note. Ledoyer’s (1979, 1986) descriptions of L. micronesiae show discrepancies with Barnard’s original description.

description: Abstract: Biological responses to climate change have been widely documented across taxa and regions, but it remains unclear whether species are maintaining a good match between phenotype and environment, i.e. whether observed trait changes are adaptive. Here we reviewed 10,090 abstracts and extracted data from 71 studies reported in 58 relevant publications, to assess quantitatively whether phenotypic trait changes associated with climate change are adaptive in animals. A meta-analysis focussing on birds, the taxon best represented in our dataset, suggests that global warming has not systematically affected morphological traits, but has advanced phenological traits. We demonstrate that these advances are adaptive for some species, but imperfect as evidenced by the observed consistent selection for earlier timing. Application of a theoretical model indicates that the evolutionary load imposed by incomplete adaptive responses to ongoing climate change may already be threatening the persistence of species.

description: We consider a planar Coulomb gas in which the external potential is generated by a smeared uniform background of opposite-sign charge on a disc. This model can be seen as a two-dimensional Wigner jellium, not necessarily charge neutral, and with particles allowed to exist beyond the support of the smeared charge. The full space integrability condition requires low enough temperature or high enough total smeared charge. This condition does not allow at the same time, total charge neutrality and determinantal structure. The model shares similarities with both the complex Ginibre ensemble and the Forrester--Krishnapur spherical ensemble of random matrix theory. In particular, for a certain regime of temperature and total charge, the equilibrium measure is uniform on a disc as in the Ginibre ensemble, while the modulus of the farthest particle has heavy-tailed fluctuations as in the Forrester--Krishnapur spherical ensemble. We also touch on a higher temperature regime producing a crossover equilibrium measure, as well as a transition to Gumbel edge fluctuations. More results in the same spirit on edge fluctuations are explored by the second author together with Raphael Butez.

description: Nucleon-nucleon (NN) forces from chiral perturbation theory at next-to-leading (NLO) and next-to-next-to-leading order (NNLO) are applied to systems with two, three and four nucleons. At NNLO, we consider two versions of the chiral potential which differ in the strength of the two-pion-exchange (TPE) but describe two nucleon observables equally well. The NNLO potential leads to unphysical deeply bound states in the low partial waves and effects of the 3N forces, which appear first at this order, are expected to be large. We provide arguments for a reduction of the TPE potential and introduce the NNLO* version of the NN forces. We calculate nd scattering observables as well as various properties of 3H and 4He with the NNLO* potential and find good agreement with the data and with predictions based upon the standard high-precision potentials. We find an improved description of the 3H and 4He binding energies.

description: No conscious attempt will be made in these remarks to relate adjustments .in marketing to adjustments in farm productiono I am not an agricultural fundameptalist but I am an agricultural realist. As such, I recognize that some farm prdplems find their source in the marketing area but my focus is not there today. > Marketing adjustments lie against a backdrop of declining food industries~ in terms of numbers. Often these adjustments hit the small tOW"n industrial and S social complex the hardesto These adjustments increasingly result in more of ithe agribusiness complex. The closeness of interrelationships between production and marketing will grow. · Against this setting let us talk, and dramatize a bit, four basic adjust~ents bearing on you and your businesses. If the drama looms large, remember that t~~ very continuity of evolutionary changes in marketing is most disarming.

description: This study protocol falls within WP2 of HIGH Horizons (assessment of health impacts and facilities), task 2.1 (population-level impacts: measurement). Analyses of heat-health impacts and data science predictive modelling using population-level data from Sweden, Italy (Lazio region), Greece and data from health facilities in Kenya and South Africa (Gauteng province) underpin all other activities in HIGH Horizons. These analyses, along with systematic reviews, will inform testing and selection of global, EU and national indicators. Analyses will also inform cut-off thresholds for an Early Warning System (EWS), whereby a smartphone app (ClimApp-MCH) will deliver personalised warnings and context-specific messages, co-designed locally.

The aim of the epidemiological study is to generate evidence to inform the testing and selection of global, EU and national indicators of heat exposure on maternal, neonatal, and child health (MNCH), and to inform cut-off thresholds for a personalised early warning system for pregnant and postpartum women, infants and health workers.

The primary objectives of this study are:1)    To quantify relationships between ambient temperature exposures and risk of adverse maternal, neonatal, and child health outcomes;2)    To identify the relative temperature threshold(s) above which risk of an adverse outcome is increased;3)    To determine valid and reliable heat indicators for assessing heat-MNCH impacts at population-level;4)    To characterise groups of pregnant women and children at high risk of heat-related conditions;5)    To determine if heat-MNCH associations vary by location, climate, facility, or quality of care, as the data allow.Our secondary objectives are:6)    To identify critical windows of susceptibility during gestation or during infancy and childhood; 7)    To explore impacts of both acute and cumulative heat exposures.
Photon Self-Energy in a Color Superconductor

description: In a color superconductor the diquark condensates break spontaneously both the color and ordinary electromagnetism, leaving a remanining rotated U(1) symmetry unbroken. The gauge interactions associated to this rotated symmetry may be considered as the in-medium electromagnetism. We compute the in-medium photon self-energy in the presence of diquark condensates at high baryonic density and weak coupling. This is done to one-loop order for the cases of two and three quark flavors. For vanishing temperature, a detailed discussion is given of the low momentum behavior of the photon polarization tensor. A simple physical picture for the propagation of light in color superconducting media is obtained. The main new effect is due to the diquark condensates, which lead to a strong dielectric constant of the medium. The magnetic permeability remains unchanged, because the primary condensates have vanishing spin and angular momentum. In the two flavor case, an additional contribution arises due to gapless quarks and electrons, which is responsible for Debye screening effects. We also discuss the low energy effective theory for the three flavor case in the presence of electromagnetic interactions.

description: Ever since 2012, the EU ETS (European Union’s Emission Trading Scheme), which is the EU’s climate policy was extended to include the ESD (Effort Sharing Decision) sectors’ (agriculture, transport, building) regulations. As its name implies, this mechanism is based off of shared interests and efforts, all in order to reach the climate goals. Therefore, analysing the agriculture sector from an environmental viewpoint requires the analysis of related sectors as well, since their performances will have an impact on determining the requirements to be met by the agriculture. Seeing that those primarily present in said sectors are not various firms, but people and public utility management institutions instead, the level of regulations draws from the economic state of the various countries in question (GDP per capita). Therefore, member states like ours did not receive difficult goals until 2020, due to our performance being lower than the average of the EU. However, during the program phase between 2021 and 2030, all nations are to lower their GHG (greenhouse gases) emission, and have to make developments to restrict GHG emission level growth within the ESD, which means we already have to estimate our future possibilities. During the analyses, we will see that analysing agriculture from an environmental viewpoint, without doing the same to their related sectors and their various related influences is impossible. The GHG emission goals determined by the EU have to be cleared by the agriculture sector, but the inputs from transport, waste management and building are required nonetheless.
