description: We propose a scenario with string theory in the deep ultraviolet, an intermediate asymptotically safe scaling regime for gravity and matter, and the Standard Model in the infrared. This could provide a new perspective to tackle challenges of the two models: For instance, the gravitational Renormalization Group flow could connect a negative microscopic to a positive macroscopic cosmological constant, potentially rendering string theory on an anti-de Sitter background observationally viable. Further, the unitarity of a string-theoretic ultraviolet completion could be inherited by an asymptotically safe fixed point, despite the presence of higher-order interactions. We discuss necessary conditions on the scale of asymptotic safety and the string scale for our scenario to be viable. As a first test, we explore the weak-gravity conjecture in the context of asymptotically safe gravity.

description: Objectives: To collect information on endodontic treatment procedures among dentists in the public dental service (PDS) in Western Norway and relate this information to their work experience. Materials and methods: A survey comprised of 35 questions related to personal information, frequency of endodontic treatment, endodontic procedures and treatment principles was distributed electronically to 187 dentists in PDS in two counties of Western Norway. Results: The response rate was 74%, and 130 dentists participated. Among them, 57.0% had completed their education less than 13 years ago, and almost all were below 39 years old (95%). The majority (81.0%) had graduated in Norway. Stepwise caries excavation in primary and permanent teeth and direct pulp capping in primary teeth were more frequently performed by dentists with less than 13 years from graduation. Routine use of rubber dam was high among the responders (87%). However, use of rubber dam and master-cone radiograph uptakes were more frequent among the younger dentists. The majority used rotary instrumentation systems, and almost all participants followed the current guidelines for use of antibiotics in endodontics. Conclusions: In general, dentists in PDS follow the current endodontic treatment guidelines. However, it seems that the more recently graduated dentists perform more endodontic procedures and tend to adhere more to the taught principles regarding rubber dam use and radiograph uptakes.

description: BeppoSAX observed the Seyfert 1 galaxy NGC 3783 for ~ 5 days from 1998 June 6 to 1998 June 10. The average flux during the observation was F(2-10 keV) ~ 6 X 10^{-11} erg cm^-2 s^-1. The long exposure provided a very high quality spectrum that exhibits all the typical features of Seyfert 1s. The high energy cut-off of the intrinsic continuum, at E_c=340+560/-107 keV, was detected for the first time in this object. During the observation the source showed modest flux variations (~ 20% in 2-10 keV) and spectral variability that can be completely explained by a change of the intrinsic slope ΔΓ~ 0.1. NGC 3783 is one of the few Seyfert 1s that exhibits a soft emission component in the BeppoSAX spectrum. This soft excess is well reproduced by a black body component with temperature kT ~ 0.2 keV. A warm absorber is also required to fit the soft X-ray spectrum. Both reprocessing features, the Compton reflection hump and the Fe emission line, were detected in our observation. In addition to a narrow iron line (as observed by Chandra) a broad component with sigma=0.72 +1.28/-0.27 keV and EW=115+/-76 eV, is required to fit the line. The observed Compton hump and the Fe line are well reproduced with the ionized (lg(xi)=2.73+0.04/-0.05) disc reflection model of Ross & Fabian. In this case the soft excess observed below 2 keV can be accounted for by the disc emissivity and no additional soft X-rays component is required to fit the spectrum.

description: Background: Towards the improvement of stakeholders’ awareness of animal tungiasis, we report 10 unusual severe clinical cases of pig tungiasis which were associated with very high infection intensities of T. penetrans in an endemic area. Results: Morbidity of ten pigs with high sand flea intensities detected during high transmission seasons in an endemic area in Busoga sub region, Uganda is described in detail. The cases of pigs presented with a very high number of embedded sand fleas (median = 276, range = 141–838). Acute manifestations due to severe tungiasis included ulcerations (n = 10), abscess formation (n = 6) and lameness (n = 9). Chronic morphopathological presentations were overgrowth of claws (n = 5), lateral deviation of dew claws (n = 6), detachment (n = 5) or loss of dew claws (n = 1). Treatment of severe cases with a topical insecticidal aerosol containing chlorfenvinphos, dichlorvos and gentian violet resolved acute morbidity and facilitated healing by re-epithelialisation. Conclusions: The presentations of tungiasis highlighted in this report show that high intensities of embedded T. penetrans can cause a severe clinical disease in pigs. Effective tungiasis preventive measures and early diagnosis for treatment could be crucial to minimize its effects on animal health.
Electroweak corrections to the fermionic decays of heavy Higgs states

description: Extensions of the Standard Model often come with additional, possibly electroweakly charged Higgs states, the prototypal example being the Two-Higgs-Doublet Model. While collider phenomenology does not exclude the possibility for some of these new scalar fields to be light, it is relatively natural to consider masses in the multi-TeV range, in which case the only remaining light Higgs boson automatically receives SM-like properties. The appearance of a hierarchy between the new-physics states and the electroweak scale then leads to sizable electroweak corrections, e. g. in the decays of the heavy Higgs bosons, which are dominated by effects of infrared type, namely Sudakov logarithms. Such radiative contributions obviously affect the two-body decays, but should also be paired with the radiation of electroweak gauge bosons (or lighter Higgs bosons) for a consistent picture at the one-loop order. Resummation of the leading terms is also relatively easy to achieve. We re-visit these questions in the specific case of the fermionic decays of heavy Higgs particles in the Next-to-Minimal Supersymmetric Standard Model, in particular pointing out the consequences of the three-body final states for the branching ratios of the heavy scalars.

Complexation of 4 with CB[7] in the form of CB[7]•4•2PF6 allows the preparation of assembly 7 which contains 1.95 mechanically interlocked CB[7] units. Assemblies 6 and 7 are hydrolytically unstable due to their imine linkages. Redesign of our system with water stable 2,2ʹ-bipyridine end groups was realised in the form of ligands 11 and 16. Self-assembly of 11 with Fe(NTf2)2 gave tetrahedral MOP 12. Isomeric ligand 16 underwent self-assembly with Fe(OTf)2 to give cube 17. Precomplexation of ligands 11 and 16 with CB[7] gave the acetonitrile soluble CB[7]•11•2PF6 and CB[7]•16•2PF6 complexes. Self-assembly of CB[7]•11•2PF6 with Fe(OTf)2 gave tetrahedron 13 which contains 1.8 mechanically interlocked CB[7] units. Self-assembly of CB[7]•16•2PF6 with Fe(OTf)2 gave cube 13 which contains 6.59 interlocked CB[7] units.

description: The cost of mental illness in Australia is approximately $19.1 billion each year (Australian Institute of Health and Welfare, 2022a). This figure is estimated from the cost of mental health-related services in Australia and includes state/territory mental health services and government benefits for Medicare-subsidised mental health-specific services in 2019 to 2020. A World Health Organization scoping review provided evidence that performing arts activities can trigger psychological, physiological, social and behavioural responses linked to good health outcomes and the prevention of a range of mental health conditions (Fancourt & Finn, 2019). This research investigates theatre-based interventions as having an impact on mental health and suicidality through two studies. Study 1 involves a systematic literature review to identify theatre interventions measuring the impact on mental health and/or suicidality. Studies were eligible if they used theatre interventions to investigate the impact on mental health and/or suicidality. Study 2 involved qualitative interviews with two Australian and one New Zealand organisation that facilitate mental health and wellbeing-related theatre programs. [...]

Subjects: subject: V position (knee)

description: The objectives of this study were to find the prevalence of knee bend at point of contact in the forehand groundstroke and to find the height of the ball when contacted. Both areas are yet to be considered or defined as one. In this thesis, the term "V Position" is used to describe and identify a playing position when these two areas are considered together. The V Position is defined as the use of knee bend and a height of point of contact that is at/around or below a player's hip height and can be used as a visual reference point for coaches. Using notational analysis, 121,770 individual notations were acquired to determine the prevalence of the V Position over 11 variables, in 123 players, ranked inside the top 200 on the Women's Tennis Association (WTA), or Association of Tennis Professionals (ATP) tour. A theoretical framework for the research problem was derived from a broad canvass of learning theory, including Bruner’s (1961) discovery learning, Bandura’s (1962, 1991) social learning, Vygotsky’s (1980) cognition theory and Gagné’s (1984) conditional learning phases. Concepts were also drawn from an analysis of research literature into the application of learning approaches such as Teaching Games for Understanding (TGfU) (Wu et al., 2012). Survey (n = 46) and interview (n = 9) data were collected, followed by a thematic analysis, to explain how the best coaches in the world communicate the V Position.

description: We present a strategy for a statistically rigorous Bayesian approach to the problem of determining cosmological parameters from the results of observations of anisotropies in the cosmic microwave background. Our strategy relies on Markov chain Monte Carlo methods, specifically the Metropolis-Hastings algorithm, to perform the necessary high-dimensional integrals. We describe the Metropolis-Hastings algorithm in detail and discuss the results of our test on simulated data.

description: The quasi-thermal components found in many Fermi gamma-ray bursts (GRBs) imply that the photosphere emission indeed contributes to the prompt emission of many GRBs. But whether the observed spectra empirically fitted by the Band function or cutoff power law, especially the spectral and peak energy ($E_{p}$) evolutions can be explained by the photosphere emission model alone needs further discussion. In this work, we investigate in detail the time-resolved spectra and $E_{p}$ evolutions of photospheric emission from a structured jet, with an inner-constant and outer-decreasing angular Lorentz factor profile. Also, a continuous wind with a time-dependent wind luminosity has been considered. We show that the photosphere spectrum near the peak luminosity is similar to the cutoff power-law spectrum. The spectrum can have the observed average low-energy spectral index $α$ $ \sim -1$, and the distribution of the low-energy spectral index in our photosphere model is similar to that observed ($-2\lesssim $ $α\lesssim 0$). Furthermore, the two kinds of spectral evolutions during the decay phase, separated by the width of the core ($θ_{c}$), are consistent with the time-resolved spectral analysis results of several Fermi multi-pulse GRBs and single-pulse GRBs, respectively. Also, for this photosphere model we can reproduce the two kinds of observed $E_{p}$ evolution patterns rather well. Thus, by considering the photospheric emission from a structured jet, we reproduce the observations well for the GRBs best fitted by the cutoff power-law model for the peak-flux spectrum or the time-integrated spectrum.

Theory of coherent oscillations detection in THz pump-probe spectroscopy: from phonons to electronic collective modes

description: Time-resolved spectroscopies using intense THz pulses appear as a promising tool to address collective electronic excitations in condensed matter. In particular recent experiments showed the possibility to selectively excite collective modes emerging across a phase transition, as it is the case for superconducting and charge-density-wave (CDW) systems. One possible signature of these excitations is the emergence of coherent oscillations of the differential probe field in pump-probe protocols. While the analogy with the case of phonon modes suggests that the basic underlying mechanism should be a sum-frequency stimulated Raman process, a general theoretical scheme able to describe the experiments and to define the relevant optical quantity is still lacking. Here we provide this scheme by showing that coherent oscillations as a function of the pump-probe time delay can be linked to the convolution in the frequency domain between the squared pump field and a Raman-like non-linear optical kernel. This approach is applied and discussed in few paradigmatic examples: ordinary phonons in an insulator, and collective charge and Higgs fluctuations across a superconducting and a CDW transition. Our results not only account very well for the existing experimental data in a wide variety of systems, but they also offer an useful perspective to design future experiments in emerging materials.

description: In the context of gravity's rainbow, we study the deformed Starobinsky model in which the deformations take the form $f(R)\sim R^{2(1-α)}$, with $R$ the Ricci scalar and $α$ a positive parameter. We show that the spectral index of curvature perturbation and the tensor-to-scalar ratio can be written in terms of $N,\,λ$ and $α$, with $N$ being the number of {\it e}-foldings, $λ$ a rainbow parameter. We compare the predictions of our models with Planck data. With the sizeable number of {\it e}-foldings and proper choices of parameters, we discover that the predictions of the model are in excellent agreement with the Planck analysis. Interestingly, we obtain the upper limit and the lower limit of a rainbow parameter $λ$ and a positive constant $α$, respectively.

description: In this paper we present preliminary spectroscopic results from a small area faint K-excess (KX) survey, and compare KX selection against UVX selection. The aim of the KX method is to produce complete samples of QSOs flux-limited in the K band, in order to minimize any selection bias in samples of QSOs from the effects of reddening and extinction. Using the photometric catalogue of the ESO Imaging Survey Chandra Deep Field South (48 arcmin^2) we have identified compact objects with J-K colours redder than the stellar sequence, that are brighter than K=19.5. We have obtained spectra of 33 candidates, using the LDSS++ spectrograph on the AAT. Amongst the 11 bluer candidates, with V-J<3, three are confirmed as QSOs. Identification of the 22 redder candidates with V-J>3 is substantially incomplete, but so far no reddened QSOs have been found. Near-infrared spectroscopy will be more effective in identifying some of these targets. Only two UVX (U-B3) is substantially incomplete, the 2sigma upper limit on the density of reddened QSO is large, <1150 deg^-2. As anticipated, at these faint magnitudes the KX sample includes several compact galaxies. Of the 14 with measured redshifts, there are roughly equal numbers of early and late type objects. Nearly all the early type galaxies are found in a single structure at z=0.66.

description: We present a simple model based on the dark halo approach which provides a useful way to understand key points determining the shape of the non-Gaussian tails of the dark matter one-point probability distribution function(PDF). In particular, using the scale-free models with power-law profile of dark halos, we derive a simple analytic expression for the one-point PDF. It is found that the shape of the PDF changes at the characteristic value of $δ_*$ which is defined by the smoothed density of a halo with the characteristic mass $M_*$ at the epoch. In cold dark matter models with top-hat smoothing filters, the characteristic smoothed density at present time typically takes the value $δ_*\gg 1$ for a small smoothing scale $\rth\sim 1$Mpc$/h$ and conversely $δ_*\ll 1$ for a large smoothing scale $\rth > 10$Mpc$/h$. On the range $δ/δ_*<1$, the shape of the PDF is almost solely determined by the outer slope of halos and scales as a power-law. The resultant non-Gaussian tails of PDF then resemble the log-normal PDFs in that range and show a good agreement with N-body simulations, which can be ascribed to the universality of the outer slope of the halo profile. In contrast, tails of one-point PDF in the range $δ/δ_*>1$ basically follow the steep exponential tails of the halo mass function, which exhibit a strong sensitivity to both the outer slope of the halo profile and the initial power spectrum. Based on these results, the discussion on the PDF of galaxy distribution and the application to the weak lensing statistics are also presented.

REMARKS
Gagnepain (1929) identified Magnolia echinina P.Parm. as belonging to Unona discolor Vahl. This lead allowed me to track down the type and confirm that Gagnepain was correct, though the accepted name for this species is now Desmos chinensis Lour. (Annonaceae).

description: Excerpts from the report: The Special Milk Program was initiated in public and private schools in September 1954, pursuant to Public Law 690, 83rd Congress. This law amended a price-support provision of the Agricultural Act of 1949. Beginning with the 1957 fiscal year, the program was broadened to include summer camps, nursery schools, orphanages, and similar child-care institutions. The primary purpose of the program is to increase milk consumption among children through lowering its cost to them and thereby making it more readily available. This study of factors affecting milk consumption in summer camps is one in a series of reports evaluating selected aspects of public programs. The research on which it is based is part of a broad program designed to expand the market for farm products. Specific objectives were to obtain information upon which educational programs might be developed to encourage increased consumption of milk in nonprofit summer camps and to provide a better basis for milk producers, processors, and distributors to appraise the potential market for whole milk in this outlet. The study was conducted in July and August 1958 in a random sample of 109 nonprofit resident summer camps participating in the Special Milk Program. The sample was representative of all such camps in the States of Maine, Massachusetts, and New York.

description: Sphaerodinium fimbriatum R.H.Thompson (1950: 296). Figure 18
Dimensions: L: 43–45 µm, Td: 34–39 µm.
Cell shape: Rounded, oval, dorsoventrally slightly compressed. Plate margins very prominent as fimbriate lists, present in both the epithecal and the hypothecal plates (Fig. 18C). Prominent plate margins, both in the epitheca and the hypotheca, in the form of fimbriate lists.
Thecal characteristics: Tabulation, 4ʹ, 4a, 7ʹʹ, 7c, 6s, 6ʹʹʹ, 2ʹʹʹʹ (Figs. 18C and 18D), without apical pore. The plate 1ʹ narrow, elongated, flanked by 2ʹ and 4ʹ plates, and not contacting 1ʹʹ and 7ʹʹ plates (Fig 18C). This character does not appear in the order Peridiniales. The 3ʹ is hexagonal and the four anterior intercalary plates are almost isodiametrical.
Cingulum and sulcus: Equatorial cingulum. Narrow sulcus, the Sa plate enters into the epitheca and is in contact with the first and the last pre-cingular plates (Fig. 18C).
Ornamentation: The margins of the plates, very prominent, easily visible with light microscopy (Fig. 18B). The margin border present outstanding nodules, such as fimbriae (Fig. 18C). The epithecal plates have a rough texture, without any ornamentation, while each hypothecal plate has a central prominent strip, similar in appearance to the projections of the plate margins (Figs. 18C, E).
Localities: Ayapel and Zapatosa in North Colombia.
 Commentaries: This is the first record of both the genus and the species Sphaerodinium fimbriatum in Colombia. The species is an easily recognizable, due to the shape of the theca and the curved edges when observed with LM. The specimens observed match the original description (Thompson 1951) and are in the size range (Table 10) mentioned in the literature (Carty 2014; Moestrup & Calado 2018).
World distribution: Ivory Coast and USA (Moestrup & Calado 2018).

description: We report the first detection of galactic spiral structure by means of thermal emission from magnetically aligned dust grains. Our 89 $μ$m polarimetric imaging of NGC 1068 with the High-resolution Airborne Wideband Camera/Polarimeter (HAWC+) on NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) also sheds light on magnetic field structure in the vicinity of the galaxy's inner-bar and active galactic nucleus (AGN). We find correlations between the 89 $μ$m magnetic field vectors and other tracers of spiral arms, and a symmetric polarization pattern as a function of the azimuthal angle arising from the projection and inclination of the disk field component in the plane of the sky. The observations can be fit with a logarithmic spiral model with pitch angle of $16.9^{+2.7}_{-2.8}$$^{\circ}$ and a disk inclination of $48\pm2^{\circ}$. We infer that the bulk of the interstellar medium from which the polarized dust emission originates is threaded by a magnetic field that closely follows the spiral arms. Inside the central starburst disk ($<1.6$ kpc), the degree of polarization is found to be lower than for far-infrared sources in the Milky Way, and has minima at the locations of most intense star formation near the outer ends of the inner-bar. Inside the starburst ring, the field direction deviates from the model, becoming more radial along the leading edges of the inner-bar. The polarized flux and dust temperature peak $\sim 3-6$" NE of the AGN at the location of a bow shock between the AGN outflow and the surrounding interstellar medium, but the AGN itself is weakly polarized ($< 1$%) at both 53 and 89 \um.

description: We calculate the trace (conformal) anomaly for chiral fermions in a general curved background using Hadamard subtraction. While in intermediate steps of the calculation imaginary terms proportional to the Pontryagin density appear, imposing a vanishing divergence of the stress tensor these terms completely cancel, and we recover the well-known result equal to half the trace anomaly of a Dirac fermion. We elaborate in detail on the advantages of the Hadamard method for the general definition of composite operators in general curved spacetimes, and speculate on possible causes for the appearance of the Pontryagin density in other calculations.

description: A series of new symmetric monomer comprising 2,6-dihydroxynaphthalene as central unit with extended side arms made up by biphenyl system and the terminal alkoxy chains, OCnH2n+1 (n = 7–12) have been successfully prepared and their mesomorphic behaviors were investigated. The naphthalene derivative with shorter terminal alkoxy chains ranging from n = 7 to n = 10 were found to display enantiotropic nematic (N) phase. The homologues with undecyloxy and dodecyloxy derivatives are enantiotropic N phase with the emergence of monotropic smectic C phase. The rigidity and polarizability of naphthalene core causes wide N phase transition temperature range.

description: The face-on spiral galaxy M74 (NGC 628) was observed by XMM on 2002 February 2. In total, 21 sources are found in the inner 5' from the nucleus (after rejection of a few sources associated to foreground stars). Hardness ratios suggest that about half of them belong to the galaxy. The higher-luminosity end of the luminosity function is fitted by a power-law of slope -0.8. This can be interpreted as evidence of ongoing star formation, in analogy with the distributions found in disks of other late-type galaxies. A comparison with previous Chandra observations reveals a new ultraluminous X-ray transient (L_x \~ 1.5 x 10^39 erg/s in the 0.3--8 keV band) about 4' North of the nucleus. We find another transient black-hole candidate (L_x ~ 5 x 10^38 erg/s) about 5' North-West of the nucleus. The UV and X-ray counterparts of SN 2002ap are also found in this XMM observation.

description: Four new rearranged eudesmane sesquiterpenoids, Lyciiterpenoids A-D (1–4), together with four known compounds (5–8) were isolated from the aqueous extract of Lycii Cortex. Their structures were elucidated by spectroscopic analysis, and the absolute configurations of compounds 1–4 were determined by the quantum chemical ECD calculations. The absolute configuration of 1 was further confirmed by X-ray crystallographic data analysis. All the isolated compounds were evaluated for their cytotoxicity against three human cancer cell lines (MCF-7, HepG2, and A549). However, no significant activities were detected even with a concentration up to 100 μM.

description: The theory of communication through coherence (CTC) proposes that brain oscillations reflect changes in the excitability of neurons, and therefore the successful communication between two oscillating neural populations depends not only on the strength of the signal emitted but also on the relative phases between them. More precisely, effective communication occurs when the emitting and receiving populations are properly phase locked so the inputs sent by the emitting population arrive at the phases of maximal excitability of the receiving population. To study this setting, we consider a population rate model consisting of excitatory and inhibitory cells modelling the receiving population, and we perturb it with a time-dependent periodic function modelling the input from the emitting population. We consider the stroboscopic map for this system and compute numerically the fixed and periodic points of this map and their bifurcations as the amplitude and the frequency of the perturbation are varied. From the bifurcation diagram, we identify the phase-locked states as well as different regions of bistability. We explore carefully the dynamics emphasizing its implications for the CTC theory. In particular, we study how the input gain depends on the timing between the input and the inhibitory action of the receiving population. Our results show that naturally an optimal phase locking for CTC emerges, and provide a mechanism by which the receiving population can implement selective communication. Moreover, the presence of bistable regions, suggests a mechanism by which different communication regimes between brain areas can be established without changing the structure of the network
