description: Introduction Data augmentation is a technique commonly used in expanding image dataset by artificially creating new images based on real original images. However, studies on data augmentation effects on medical images are limited.1,2,3 This work compared traditional augmentation techniques including rotating, shearing, flipping, and Gaussian addictive noise on monochromic and polychromic medical images. Methodology Two different types of medical image were acquired from open source. A total of 7048 skin diseases images with 4879 benign lesions and 2169 malignant lesions, labelled with diagnosis verified by histopathology and a set of 5856 pediatric chest radiographs acquired from a retrospective cohort were used. VGG16 Net was constructed for training.4 Original dataset mixed with different types of augmentation techniques were used for training.5 After training, each networks tested for their performance based on recall, precision and F1 score. Results Experiments showed gray-scale chest radio-graph performed better than color-scale skin disease images in VGG16 Net with recall and precision more than 0.95 in identifying pneumonia. Rotation technique had best F1score for skin images and performed equally well in chest. On the other hand, flipping had improved neural net performance for chest radiograph slightly more compared to other techniques. Meanwhile, training using augmented images alone had worst achievement than others. Discussion / Conclusion Data augmentation is applicable in both types of medical images when combining together with original datasets, giving merits for generalization. Both monochromic and polychromic medical images classifiers have various degree of boosted performance with all types of data augmentation techniques. Training of medical image classifier is not indifferent towards type of data augmentations, rotation can provide better recall which is favored in real world. It would be better to train together with original images than only augmented image, because latter alone has no benefits towards medical image training.

description: The structure functions $F_1$ and $F_2$ of the hadronic tensor of vector mesons are obtained at order $1/N$ and strong coupling using the gauge/gravity duality. We find that the large $N$ limit and the high energy one do not commute. Thus, by considering the high energy limit first, our results of the first moments of $F_1$ for the rho meson agree well with those from lattice QCD, with an important improvement of the accuracy with respect to the holographic dual calculation in the planar limit.

description: Aims: Gastrostomy feeding represents a vital component of supportive care provided to people with swallowing or feeding difficulties; however, the rate of specific long-term complications is currently unknown in the adult population. This study aimed to determine the prevalence of specific long-term gastrostomy-related complications and unplanned replacements in adults. Methods: A prospective systematic review of Medline, CINAHL and Embase databases was performed. Key complications of hypergranulation, infection and displacement among studies relevant to percutaneous endoscopic gastrostomy tubes, radiologically inserted gastrostomy tubes and balloon replacement tubes were critically appraised by two independent reviewers. Results were synthesised quantitatively in a meta-analysis using random effects where the population and condition were sufficiently homogeneous. Results: In total, 453 studies were identified, of which 17 met inclusion criteria. 8.5% of adults with a gastrostomy were found to have had an infection ≥42 days after initial tube insertion (p < 0.01), while 13% had hypergranulation (p < 0.01). Displacement occurred in 10.8% of adults (p < 0.01), with age (p < 0.001) and sex (p < 0.001) presenting as a risk factor (R2 = 75%) following meta-regression. Conclusions: Approximately 1 in 10 people with a gastrostomy will experience a complication related to either hypergranulation, infection or dislodgement. Age, in combination with sex, may provide a guide for risk of displacement among adult female cohorts, though further studies reporting prevalence of gastrostomy-related complications along with participant demographics are required.

Third order extensions of $3d$ Chern-Simons interacting to gravity: Hamiltonian formalism and stability

description: We consider inclusion of interactions between 3d Einstein gravity and the third order extensions of Chern-Simons. Once the gravity is minimally included into the third order vector field equations, the theory is shown to admit a two-parameter series of symmetric tensors with on-shell vanishing covariant divergence. The canonical energy-momentum is included into the series. For a certain range of the model parameters, the series include the tensors that meet the weak energy condition, while the canonical energy is unbounded in all the instances. Because of the on-shell vanishing covariant divergence, any of these tensors can be considered as an appropriate candidate for the right hand side of Einstein's equations. If the source differs from the canonical energy momentum, the coupling is non-Lagrangian while the interaction remains consistent with any of the tensors. We reformulate these not necessarily Lagrangian third order equations in the first order formalism which is covariant in the sense of 1+2 decomposition. After that, we find the Poisson bracket such that the first order equations are Hamiltonian in all the instances, be the original third order equations Lagrangian or not. The brackets differ from canonical ones in the matter sector, while the gravity admits the usual PB's in terms of ADM variables. The Hamiltonian constraints generate lapse, shift and gauge transformations of the vector field with respect to these Poisson brackets. The Hamiltonian constraint, being the lapse generator, is interpreted as strongly conserved energy. The matter contribution to the Hamiltonian constraint corresponds to 00-component of the tensor included as a source in the right hand side of Einstein equations. Once the 00-component of the tensor is bounded, the theory meets the usual sufficient condition of classical stability, while the original field equations are of third order.

description: We study $ω\toπ^+π^-$ decay up to including all orders of the chiral expansion and one-loop level of mesons in formlism of chiral constituent quark model. This G-parity forbidden decay is caused by $m_u\neq m_d$ and electromagnetic interaction of mesons. We illustrate that in the formlism both nonresonant contact interaction and $ρ$ resonance exchange contribute to this process, and the contribution from $ρ$ resonance exchange is dominant. We obtain that transition matrix element is $=[-(3956\pm 280)-(1697\pm 130)i]$MeV$^2$, and isospin breaking parameter is $m_d-m_u=3.9\pm 0.22$MeV at energy scale $μ\sim m_ω$.

description: Earlier work reported on the existence of a term within a generalized skyrmion approach that yields appreciable spin content for the proton. Unfortunately there is no accessible experiment that can fix the coefficient of this term directly; plausible but highly uncertain values for it gave a result for the spin content loosely consistent with the currently measured $ΔΣ= 0.27\pm 0.13.$ We here attempt to narrow the range of values for this coefficient by performing global fits to all the parameters of the generalized Skyrme lagrangian while requiring reasonable results for the baryon octet and decuplet masses and octet magnetic moments. This requirement fixes the coefficient loosely, and we find that parameter sets that fit the baryon masses and magnetic moments yield proton spin content near $ΔΣ\sim 0.15.$

description: The Boussinesq equations are fundamental in meteorology. Among other aspects, they aim to model the process of front formation. We use the approach presented in [Hol15] to introduce stochasticity into the incompressible Boussinesq equations. This is, we introduce cylindrical transport noise in a way that the geometric properties in the Euler-Poincaré formulation are preserved. One of our main results establishes the local well-posedness of regular solutions for these new stochastic Boussinesq equations. We also construct a blow-up criterion and derive some general estimates, which are crucial for showing well-posedness of a wide range of similar SPDEs.

description: The classical linearised gravitational self interaction of a Goto-Nambu string is examined in four spacetime dimensions. Using a conveniently gauge independent tensorial treatment, the divergent part of the self-force is shown to be exactly zero. This is due to cancelation by a contribution that was neglected in the previous treatments. This result has implications for many applications.

Systematic Errors in the Hubble Constant Based on Measurement of the Sunyaev-Zeldovich Effect

description: Values of the Hubble constant reported to date which are based on measurement of the Sunyaev-Zeldovich (SZ) effect in clusters of galaxies are systematically lower than those derived by other methods (e.g., Cepheid variable stars, or the Tully-Fisher relation). We investigate the possibility that systematic errors may be introduced into the analysis by the generally adopted assumptions that observed clusters are in hydrostatic equilibrium, are spherically symmetric, and are isothermal. We construct self-consistent theoretical models of merging clusters of galaxies using hydrodynamical/N-body simulations. We then compute the magnitude of Ho derived from the SZ effect at different times and at different projection angles both from first principles, and by applying each of the standard assumptions used in the interpretation of observations. Our results indicate that the assumption of isothermality in the evolving clusters can result in Ho being underestimated by 10-30% depending on both epoch and projection angle. Moreover, use of the projected, emission-weighted temperature profile under the assumption of spherical symmetry does not significantly improve the situation except in the case of more extreme mergers (i.e., those involving relatively gas-rich subclusters).

Supplementing the adjoint Higgs field to a model analyzed previously, we calculate the mass matrices for the up and down quarks and charged leptons. Although the number of free parameters is less than that of observables, an overall fitting to the observed masses and mixing angles is shown to be possible. Most notably, we find two novel, parameter-independent relations between the lepton 2-3 mixing angle and the quark masses and CKM mixing angles that are in good agreement with the large lepton mixing recently observed.

Negli esemplari di questa specie che ho ricevuti provenienti dai dintorni di Cape-Town, il capo e il torace sono di colore nero opaco, talvolta tendente al rosso cupo e sono coperti di una punteggiatura fittissima, come la superficie di un ditale da cucire, sicche quelle parti del corpo potrebbero dirsi ancora reticolate a rilievo, scultura questa molto frequento nelle formiche: sul capo si osservano sparse in mezzo a questa scultura delle fossette poco profonde, il cui fondo presenta la stessa struttura della superficie circostante. L'addome e vestito di grosse setole giallo-fulve depresse, che formano una fitta vestitura, fra le quali altre simili, piu lunghe e ritte, sono disposte in due ordini trasversi per ciascun segmento. Tutti questi peli sono piantati entro dei punti obliqui sparsi fra la punteggiatimi fittissima e uniformo di tutto l'addome. Le setole sono piu scarse e sottili sui lati della faccia ventrale dell'addome e mancano nel mezzo di essa. Negli esemplari del Capo rimangono pure affatto prive di peli la base del primo segmento addominale e una macchia oblunga sulsecondo, e spesso anche una macchia sul primo e sul terzo. Si potrebbe credere a prima giunta che quello macchie nude fossero dovute a cattivo stato di conservazione degli esemplari: so cosi fosse dovrebbero potersi vedere in quelle chiazze i punti dai quali le setole fossero state staccate, come si vede benissimo laddove si tolgano ad arte i peli. Invece, nei grandi esemplari che hanno lc macchie bene sviluppate, nelle parti nude, i punti piligeri mancano affatto.
Alcuni esemplari del Damara-Land non mostrano che un piccolissimo rudimento dolla macchia denudata sul secondo segmento e nessuna traccia di macchia sul primo e terzo. â Altri individui del territorio dei Namaqua hanno invece le macchie nude molto sviluppate, quella dc 1 secondo segmento poco meno larga che lunga. In questi esemplari, como in quelli di Damara, il colore dei peli e poco meno rosseggiante che in quelli del Capo.

To understand the effects of climate warming on biota, long-term observations of the occurrence of species and detailed knowledge on their ecology and life-history is crucial. Mountain species particularly suffer under climate warming and often respond to environmental changes by altitudinal range shifts. We assessed long-term distribution trends of mountain butterflies across the eastern Alps and calculated species´ specific annual range shifts based on field observations and species distribution models, counterbalancing the potential drawbacks of both approaches. We also compiled details on the ecology, behaviour and life-history, and the climate niche of each species assessed. We found that the highest altitudinal maxima were observed recently in the majority of cases, while the lowest altitudes of observations were recorded before 1980. Mobile and generalist species with a broad ecological amplitude tended to more uphill move than specialist and sedentary species. As main drivers, we identified climatic conditions and topographic variables, such as insolation and solar irradiation. This study provides important evidence for responses of high mountain taxa to rapid climate change. Our study underlines the advantage of combining historical surveys and museum collection data with cutting-edge analyses. Appendix S4 shows the summary statistics and individual responses of all studied species to contemporary climatic fluctuations as animations.

description: We study the dynamics of an atomic BEC subject to local dissipation in the form of atom losses. We show there is a critical loss rate at which the system undergoes a continuous dissipative phase transition from a homogenous state into a state which contains a sonic horizon. The latter drastically alters the behavior of the system by screening the drain. Dissipation leads to two types of fluctuations. First, fluctuations are generated by particles emitted in the reservoir. Both above and below the critical loss, these result in thermal emission of phonons with a temperature set by the loss rate and the chemical potential. The second type of fluctuation results from scattering on the drain and gives rise to a particular correlation pattern that can be observed in the density-density correlation. Aside from correlations between in an out scattered modes, outgoing particles are correlated with localized modes through a process that is reminiscent of Hawking radiation. Finally, we briefly discuss the dynamics of the system when there are two drains, in which case it is possible to construct a black hole laser.

description: Carbon monoxide (CO) is the second most abundant molecule in the gas-phase of the interstellar medium. In dense molecular clouds, it is also present in the solid-phase as a constituent of the mixed water-dominated ices covering dust grains. Its presence in the solid-phase is inferred from its infrared (IR) signals. In experimental observations of solid CO/water mixed samples, its IR frequency splits into two components, giving rise to a blue- and a redshifted band. However, in astronomical observations, the former has never been observed. Several attempts have been carried out to explain this peculiar behaviour, but the question still remains open. In this work, we resorted to pure quantum mechanical simulations in order to shed some light on this problem. We adopted different periodic models simulating the CO/H$_2$O ice system, such as single and multiple CO adsorption on water ice surfaces, CO entrapped into water cages and proper CO:H$_2$O mixed ices. We also simulated pure solid CO. The detailed analysis of our data revealed how the quadrupolar character of CO and the dispersive forces with water ice determine the energetic of the CO/H$_2$O ice interaction, as well as the CO spectroscopic behaviour. Our data suggest that the blueshifted peak can be assigned to CO interacting {\it via} the C atom with dangling H atoms of the water ice, while the redshifted one can actually be the result of CO involved in different reciprocal interactions with the water matrix. We also provide a possible explanation for the lack of the blueshifted peak in astronomical spectra. Our aim is not to provide a full account of the various interstellar ices, but rather to elucidate the sensitivity of the CO spectral features to different water ice environments.

description: Modifications of the mu+ lifetime in matter due to muonium (M = mu+ e-) formation and other medium effects are examined. Muonium and free mu+ decay spectra are found to differ at O(alpha m_e/m_mu) from Doppler broadening and O(alpha^2 m_e/m_mu) from the Coulomb bound state potential. However, both types of corrections are shown to cancel in the total decay rate due to Lorentz and gauge invariance respectively, leaving a very small time dilation lifetime difference, (tau_M - tau_mu+)/tau_mu+ = alpha^2 m_e^2/ 2m_mu^2 \simeq 6\times 10^-10, as the dominant bound state effect. It is argued that other medium effects on the stopped mu+ lifetime are similarly suppressed.

description: There is a chance that singleton fields, that in the context of strings and membranes have been regarded as topological gauge fields that can interact only at the boundary of anti-De Sitter space, at spatial infinity, may have a more physical manifestation as costituents of massless fields in space time. The composite character of massless fields is expressed by field - current identities that relate ordinary massless field operators to singleton currents and stress-energy tensors. Naive versions of such identities do not make sense, but when the singletons are described in terms of dipole structures, then such constructions are at least formally possible. The new proposal includes and generalizes an early composite version of QED, and includes quantum gravity, super gravity and models of QCD. Unitarity of such theories is conjectural.

description: We measure the velocity dispersion, $σ$, and surface density, $Σ$, of the molecular gas in nearby galaxies from CO spectral line cubes with spatial resolution $45$-$120$ pc, matched to the size of individual giant molecular clouds. Combining $11$ galaxies from the PHANGS-ALMA survey with $4$ targets from the literature, we characterize ${\sim}30,000$ independent sightlines where CO is detected at good significance. $Σ$ and $σ$ show a strong positive correlation, with the best-fit power law slope close to the expected value for resolved, self-gravitating clouds. This indicates only weak variation in the virial parameter $α_\mathrm{vir}\proptoσ^2/Σ$, which is ${\sim}1.5$-$3.0$ for most galaxies. We do, however, observe enormous variation in the internal turbulent pressure $P_\mathrm{turb}\proptoΣ\,σ^2$, which spans ${\sim}5\rm\;dex$ across our sample. We find $Σ$, $σ$, and $P_\mathrm{turb}$ to be systematically larger in more massive galaxies. The same quantities appear enhanced in the central kpc of strongly barred galaxies relative to their disks. Based on sensitive maps of M31 and M33, the slope of the $σ$-$Σ$ relation flattens at $Σ\lesssim10\rm\;M_\odot\,pc^{-2}$, leading to high $σ$ for a given $Σ$ and high apparent $α_\mathrm{vir}$. This echoes results found in the Milky Way, and likely originates from a combination of lower beam filling factors and a stronger influence of local environment on the dynamical state of molecular gas in the low density regime.

description: The X-ray source populations within galaxies are typically difficult to identify and classify from X-ray data alone. We are able to break through this barrier by combining deep new Chandra ACIS-I observations with extensive Hubble Space Telescope imaging from the PHAT survey of the M31 disk. We detect 373 X-ray sources down to 0.35-8.0 keV flux of 10$^{-15}$ erg cm$^{-2}$ s$^{-1}$ over 0.4 square degrees, 170 of which are reported for the first time. We identify optical counterpart candidates for 188 of the 373 sources, after using the HST data to correct the absolute astrometry of our Chandra imaging to 0.1$"$. While 58 of these 188 are associated with point sources potentially in M31, over half (107) of the counterpart candidates are extended background galaxies, 5 are star clusters, 12 are foreground stars, and 6 are supernova remnants. Sources with no clear counterpart candidate are most likely to be undetected background galaxies and low-mass X-ray binaries in M31. The 58 point sources that are not consistent with foreground stars are bright enough that they could be high mass stars in M31; however, all but 8 have optical colors inconsistent with single stars, suggesting that many could be background galaxies or binary counterparts. For point-like counterparts, we examine the star formation history of the surrounding stellar populations to look for a young component that could be associated with a high mass X-ray binary. For the 40 point-like counterpart candidates associated with young populations, we find that their age distribution has two peaks at 15-20 Myr and 40-50 Myr. If we only consider the 8 counterpart candidates with typical high-mass main sequence optical star colors, their age distribution peaks mimic those of the sample of 40. Finally, we find that intrinsic faintness, and not extinction, is the main limitation for finding further counterpart candidates.

[[worker]] C. fulvopiloso simillima at minor, obscure ferruginea, abdomine nigro, capite nitidulo, subtilius reticulato, punctis sparsis inagis profundis, squama subtiliore, magis procumbente, abdomine setis pallide flavis vestito, basi denudato, segmentis 1 Â°, 2 Â°, 3 Â° que maculis denudatis multo majoribus, L. 9 1 / 2 - 13 mm.
La pubescenza di colore giallo paglierino, e non fulvo come nel fulvopilosus, lascia scoperta sul secondo segmento dell'addome una macchia che non ne raggiunge l'apice, ma, nei grandi esemplari, si estende lateralmente tanto da divenire ben piu larga che lunga. Di poco piu piccola e la macchia del terzo segmento. Quella del primo non manca neppure nei piccoli esemplari. Il capo e alquanto lucido, per sottigliezza della sua punteggiatura fondamentale; le fossette sparse del fulvopilosus sono sostituite da punti fortemente impressi. Il colore ferrugineo del capo e del torace non ha grande importanza-, perche anche in alcuni esemplari del fulvopilosus queste parti tendono piu o meno al rosso. Gli angoli del pronoto sembrano piu marcati nella nuova specie, la squama e piu sottile e maggiormente inclinata in avanti.
Non conosco forme intermedie fra il C. detritus o il fulvopilosus, di cui pero, iu ragione della grande affinita, potrebbe forse considerarsi come razza anziche come specie distinta.

C. niveosetosus Emery Ann. Mus. Civ. Genova Vol. IX., p. 364. Magretti ibid Ser. 2. Vol. I. p. 537.
Gli esemplari raccolti da Beccari in Abissinia furono da me determinati falsamente pel niveosetosus Mayr.; mi sono accorto dell'errore' ricevendo dal Capo di Buona Speranza, il vero niveosetosus. Eguale errore fu commesso dall'Andre nel determinare le formiche trovate nel Sudan dal Magretti come risulta da un esemplare comunicatomi dall'egregio collettore. Gli esemplari di Beccari e quelli di Magretti sono conformi alla descrizione del C. foraminosus Forel, so non che hanno gli scapi interamente rossi. Le setole del corpo sono di un bianco gialliccio, carattere non menzionato nella descrizione di Forel che non parla del colore dei peli eretti. Il sig. Forel mi scrive che tale e pure il colore delle setole nell'esemplare originale della collezione Saussure, proveniente dal Capo Verde.
Le specie G. niveosetosus Mayr., ursus, foraminosus e Grandidieri Forel chrysurus e erinaceus Gerst. (1) costituiscono un gruppo naturale al quale si connettono pure il C. fulvopilosus De Geer, e il nuovo C. detritus. Questo gruppo esclusivamente africano, che potrebbe chiamarsi dei Camponoti paleati, e caratterizzato da un genere particolare di setole ritte, di colore fulvo o bianchiccio, grosse, non assottigliate, anzi ingrossate all'apice. Nei C. fulvopilosus e detritus, la pubescenza dell' addome e tutta composta di setole fulve, quasi simili a quelle che, ritte in mezzo ad esse, rappresentano le serie trasverse delle altro specie. Anche il C. Berthoudi Forel appartiene forse come forma atterrante al medesimo gruppo.

description: Protoplanets may be born into dust-rich environments if planetesimals formed through streaming or gravitational instabilities, or if the protoplanetary disc is undergoing mass loss due to disc winds or photoevaporation. Motivated by this possibility, we explore the interaction between low mass planets and dusty protoplanetary discs with focus on disc-planet torques. We implement Lin & Youdin's newly developed, purely hydrodynamic model of dusty gas into the PLUTO code to simulate dusty protoplanetary discs with an embedded planet. We find that for imperfectly coupled dust and high metallicity, e.g. Stokes number $10^{-3}$ and dust-to-gas ratio $Σ_\mathrm{d}/Σ_\mathrm{g}=0.5$ , a `bubble' develops inside the planet's co-orbital region, which introduces unsteadiness in the flow. The resulting disc-planet torques sustain large amplitude oscillations that persists well beyond that in simulations with perfectly coupled dust or low dust-loading, where co-rotation torques are always damped. We show that the desaturation of the co-rotation torques by finite-sized particles is related to potential vorticity generation from the misalignment of dust and gas densities. We briefly discuss possible implications for the orbital evolution of protoplanets in dust-rich discs. We also demonstrate Lin & Youdin's dust-free framework reproduces previous results pertaining to dusty protoplanetary discs, including dust-trapping by pressure bumps, dust settling, and the streaming instability.

Temporal Properties of Cygnus X-1 During the Spectral Transitions

description: We report the results from our timing analysis of 15 RXTE observations of Cygnus X-1 throughout its 1996 spectral transitions. The entire period can be divided into 3 distinct phases: (1) transition from the hard to soft state, (2) soft state, and (3) transition from the soft state back to the hard state. The observed X-ray properties in phases 1 and 3 are remarkably similar, suggesting that the same physical processes are likely involved in triggering such transitions. The power density spectrum (PDS) during the transition can be characterized by a red noise component, followed by a white noise component which extends to roughly 1-3 Hz where it is cut off, and a steeper power law at higher frequencies. The X-ray flux also exhibits apparent quasi-periodic oscillation (QPO) with the centroid frequency varying in the range of 4-12 Hz. The QPO shows no correlation with the source flux, but becomes more prominent at higher energies. This type of PDS bears resemblance to that of other black hole candidates often observed in a so-called very high state, although the origin of the observed QPO may be very different. The low-frequency red noise has not been observed in the hard state, thus seems to be positively correlated with the disk mass accretion rate which is presumably low in the hard state and high in the soft state; in fact, it completely dominates the PDS in the soft state. In the framework of thermalComptonization models, Cui et al. (see astro-ph/9610071 and astro-ph/9610072) speculated that the difference in the observed spectral and timing properties between the hard and soft states is due to the presence of a ``fluctuating'' Comptonizing corona during the transition. Here we present the measured hard X-ray time lags and coherence functions between various energy bands, and show that the results strongly support such a scenario.

description: Corrections to hyperfine splitting and Lamb shift of order $α^2(Zα)^5$ induced by the diagrams with radiative photon insertions in the electron line are calculated in the Fried-Yennie gauge. These contributions are as large as $-7.725(3)α^2(Zα)^5/(πn^3)(m_r/m)^3m$ and $-0.6711(7)α^2(Zα)/(πn^3)E_F$ for the Lamb shift and hyperfine splitting, respectively. Phenomenological implications of these results are discussed with special emphasis on the accuracy of the theoretical predictions for the Lamb shift and experimental determination of the Rydberg constant. New more precise value of the Rydberg constant is obtained on the basis of the improved theory and experimental data.
