description: A group of Gemini quaternary ammonium surfactants with the formula CnH2n+1CONH(CH2)2N+(CH3)2(CH2)2N+(CH3)2(CH2)2NHCOCnH2n+1 · 2Y (n = 11, 13 and 15, Y = HCOO−, CH3COO− and CH3CHOHCOO−) have been synthesized by a counterion conversion process and characterized by a Fourier transform infrared spectroscopy and a mass spectroscopy. Their adsorption and self-aggregation properties are investigated by surface tension, conductivity, dynamic light scattering and transmission electron microscopy (TEM) measurements. The results show that these surfactants reduce the surface tension of water to a minimum value of 26.51 mN m−1 at a concentration of 5.72 × 10−2 mmol l−1. Furthermore, the increased alkyl chain length of the carboxylic counterions leads to the increased critical micelle concentration, the decreased degree of counterion binding (β) and the decreased self-assembly tendency, but the minimum area per surfactant molecule (Amin) adsorbed at the air–aqueous solution are similar. TEM images reveal that these surfactants self-assemble spontaneously into aggregates with vesicle or bilayer structures. It is also found that they have superior antibacterial activity at a concentration of 0.1 g l−1. The high surface activity and high antibacterial activity of the Gemini quaternary ammonium salt surfactants containing different carboxylic counterions bring more possibilities for the application in the field of biomedicine.

description: Multiple stellar populations in globular clusters (GCs) are defined and recognized by their chemical signature, with second generation stars showing the effects of nucleosynthesis in the more massive stars of the earliest component formed in the first star formation burst. High temperature H-burning produces the whole pattern of (anti)-correlations among proton-capture elements widely found in GCs. However, where this burning occurred is still debated. Here we introduce new powerful diagnostic plots to detect evidence (if any) of products from proton-capture reactions occurring at very high temperatures. To test these Detectors Of High Temperature (in short DOHT) H-burning plots we show how to put stringent constraints on the temperature range of the first generation polluters that contributed to shape the chemistry of multiple stellar population in the massive bulge GC NGC 6388. Using the largest sample to date (185 stars) of giants with detailed abundance ratios in a single GC (except omega Cen) we may infer that the central temperature of part of the polluters must have been comprised between about 100 and about 150 million Kelvin (MK) if we consider hydrostatic H-burning in the core of massive stars. A much narrower range (110 to 120 MK) is inferred if the polluters can be identified in massive asymptotic giant branch (AGB) stars.

description: We report the discovery of a spatially-resolved edge-on protoplanetary disk in the ~2-Myr-old MBM 12 young association. Our near-infrared images of LkHa 263C (MBM 12A 3C), obtained with the Hokupa'a adaptive optics system on the Gemini North telescope, clearly show two elongated reflection nebulosities separated by a dark lane, a morphology well-matched by scattered light models of an optically thick (at near-infrared wavelengths) edge-on disk. An optical spectrum of the scattered light nebulosity obtained with the Keck II telescope exhibits a spectral type of M0 +/- 0.5 (T_eff = 3850 +/- 100 K) for the central star and contains H_alpha and forbidden emission lines, which may indicate the presence of a jet. The absence of a near-infrared point source implies A_K > 9.5 toward the unseen central star. The disk is flared and has a radius of ~150 AU (at a distance of 275 pc) and an inclination of 87 degrees. The aspect ratio of the model disk in the J-band is 0.72. There is possible evidence for dust settling to the disk midplane. LkHa 263C is 4.115" from the 0.415" binary LkHa 263 A and B (MBM 12A 3A and 3B), which is itself 15.5" from LkHa 262 (MBM 12A 2). Thus, LkHa 263C may be the first disk to be clearly resolved around an individual star in a young quadruple system. The detection of a faint edge-on disk near a bright star demonstrates both the high angular resolution and the high sensitivity that can be achieved with adaptive optics imaging on large telescopes.

description: Accurate and robust detection of multi-class objects in optical remote sensing images is essential to many real-world applications such as urban planning, traffic control, searching and rescuing, etc. However, state-of-the-art object detection techniques designed for images captured using ground-level sensors usually experience a sharp performance drop when directly applied to remote sensing images, largely due to the object appearance differences in remote sensing images in term of sparse texture, low contrast, arbitrary orientations, large scale variations, etc. This paper presents a novel object detection network (CAD-Net) that exploits attention-modulated features as well as global and local contexts to address the new challenges in detecting objects from remote sensing images. The proposed CAD-Net learns global and local contexts of objects by capturing their correlations with the global scene (at scene-level) and the local neighboring objects or features (at object-level), respectively. In addition, it designs a spatial-and-scale-aware attention module that guides the network to focus on more informative regions and features as well as more appropriate feature scales. Experiments over two publicly available object detection datasets for remote sensing images demonstrate that the proposed CAD-Net achieves superior detection performance. The implementation codes will be made publicly available for facilitating future researches.
Lateral Distribution Studies for the PACT Experiment

description: Monte Carlo calculations have been done to study the possibilities of using different spatial distributions, local fluctuations and the number of Cerenkov photons in gamma ray showers to increase the sensitivity of the PACT experiment. After matching the trigger rates in data with the predictions of simulations, the energy threshold of the array for gamma rays is found to be about 900 GeV. It is shown that a lateral distribution parameter $β$ can increase the signal to noise ratio in the experiment. A typical season of 15 nights should be able to conclusively establish any source with Crab level fluxes. Two other possible parameters for increase of sensitivity are also discussed. Preliminary results on the application of the $β$ parameter to the data from PACT experiment are discussed.

description: There are a number of reasons why an examination of the defence modernisation efforts of the People's Republic of China have been of particular interest to analysts since the late 1970's. This has had much to do with what could be termed the broader context of China's economic modernisation in conjunction with an important shift in the way Beijing has come to view its strategic environment. This interest has also resulted because of the potential that China has displayed in the past for rejecting hard-won gains in the face of domestic political turmoil. The capacity must be seen to exist therefore for real resistance to military reform that can not be traced to the obvious limitations imposed by the sheer size of the armed forces or the limitations of the defence budget. The focus of this study is the long term tension that has accompanied efforts to modernise the Chinese armed forces. It is contended that the last decade has witnessed fundamental change, the underlying themes of which have already made their impact and will continue to do so despite practical and political constraints.
Quantum correlations protection through spin self-rephasing in 1-D Bose gas

description: System consisting of a number of trapped atoms evolving under the influence of external inhomogenous magnetic field undergoes spin dephasing: classically, since each atom feels different field along its trajectory, the spin rotation rates differ; as a result the average spin decays. In a quantum mechanical context this corresponds to entanglement of spin and spatial degrees of freedom and nontrivial internal spin dynamics. The spin dephasing can be prevented by tuning the interaction between the atoms. This phenomenon, called spin self-rephasing, has been observed experimentally and can increase the coherence time by a large factor. While such systems have been studied from a semiclassical point of view, a quantum mechanical description is limited, especially in the case of entangled states. In this work we provide a numerical simulation of an ab initio model and provide realistic examples of spin self-rephasing used to counteract the effect of inhomogenous magnetic field. We analyze in particular the joint effect of magnetic field inhomogeneity and interactions on the coherent and spin squeezed states evolution.

description: We consider the structure of Jordan $H$-pseudoalgebras which are linearly finitely generated over a Hopf algebra $H$. There are two cases under consideration: $H=U(\mathfrak h)$ and $H=U(\mathfrak h)# \mathbb C[Γ]$, where $\mathfrak h$ is a finite-dimensional Lie algebra over $\mathbb C$, $Γ$ is an arbitrary group acting on $U(\mathfrak h)$ by automorphisms. We construct an analogue of the Tits-Kantor-Koecher construction for finite Jordan pseudoalgebras and describe all simple ones.

description: We reassess constraints on the cosmological baryon density from observations of the mean decrement and power spectrum of the Lyman-alpha forest, taking into account uncertainties in all free parameters in the simplest gravitational instability model. The uncertainty is dominated by that of the photoionizing background, but incomplete knowledge of the thermal state of the intergalactic medium also contributes significantly to the error-budget. While current estimates of the baryon fraction from the forest do prefer values that are somewhat higher than the big bang nucleosynthesis value of Ω_b h^2 = 0.02 \pm 0.001, the discrepancy is at best about 3 σ. For instance, assuming the highest estimate of the ionizing background, as indicated by recent measurements of a large escape fraction from Lyman-break galaxies by Steidel, Pettini & Adelberger, we find Ω_b h^2 = 0.045 \pm 0.008. A recent measurement of the ionizing background from the proximity effect by Scott et al., on the other hand, implies Ω_b h^2 = 0.03 \pm 0.01. We provide an expression from which future likelihoods for Ω_b h^2 can be derived as measurements of the ionizing background improve -- consistency among constraints from the forest, nucleosynthesis and the microwave background will provide a powerful test of the gravitational instability model. We also develop a formalism which treats lower bounds on the baryon density in a statistical manner, which is appropriate if only a lower bound on the ionizing background is known. Finally, we discuss the implications of the escape fraction measurement for the age, structure and stellar content of Lyman-break galaxies.

description: Using the Fisher matrix formalism, we quantitatively investigate the constraints on a 10 dimensional space of cosmological parameters which may be obtained with future cluster surveys. We explore the dependence of the Omega_m constraint on both angular coverage and depth of field. We show that in each case there is a natural cutoff beyond which the constraints on Omega_m do not significantly improve. We also investigate the sensitivity of the constraints to changes in our knowledge of the Mass-Temperature (M-T) relation by including its normalization and scatter as two of the parameters in the Fisher matrix. To make our analysis more realistic, we have added, as priors, the Fisher matrices from hypothetical supernova and CMB experiments. We find that X-ray cluster surveys actually help to constrain the M-T relation, and explore the implications of this result.

description: We discuss a 1D variational problem modeling an elastic sheet on water, lifted at one end. Its terms include the membrane and bending energy of the sheet as well as terms due to gravity and surface tension. By studying a suitable Gamma-limit, we identify a parameter regime in which the sheet is inextensible, and the bending energy and weight of the sheet are negligible. In this regime, the problem simplifies to one with a simple and explicit solution.

description: In this paper, we present and analyze measurements of the positron induced electron spectra (PIES) from highly oriented pyrolytic graphite (HOPG). The spectra were obtained using a time of flight spectrometer attached to a variable energy positron beam. In the first measurements presented, the system was configured to obtain high resolution data from the annihilation induced KVV Auger transition of carbon. In the second set of data presented, PIES spectra were obtained for 3 different positron beam energies (1.25 eV, 3.5 eV and 4.5 eV). The resulting time of flight (ToF)-PIES exhibit contributions arising from either positron annihilation induced Auger processes (PAES), Auger mediated positron sticking (AMPS), or secondary electron emission. Our analysis indicates that for incident positron energies 3.5 eV and less, the ToF-PIES can be accounted for considering only two mechanisms: positron annihilation induced Auger processes or positron sticking.

In this paper we study general continuous potentials. We demonstrate that the Weyl functions of the corresponding auxiliary Dirac spectral problem carry a natural Poisson structure. We call it the Atiyah--Hitchin Poisson bracket. We show that the Poisson bracket on the phase space is the image of the Atiyah--Hitchin bracket on Weyl functions under the inverse spectral transform.

description: We have developed a fast, accurate and generally applicable method for inferring the power spectrum and its uncertainties from maps of the cosmic microwave background (CMB) in the presence of inhomogeneous and correlated noise. For maps with 10 to 100 thousand pixels, we apply an exact power spectrum estimation algorithm to submaps of the data at various resolutions, and then combine the results in an optimal manner. To analyze larger maps efficiently one must resort to sub-optimal combinations in which cross-map power spectrum error correlations are only calculated approximately. We expect such approximations to work well in general, and in particular for the megapixel maps to come from the next generation of satellite missions.

description: Elemental abundances of carbon, nitrogen, oxygen, magnesium, aluminum, and silicon are presented for a sample of twelve rapidly rotating OB star (v sin i > 60 km s^-1) members of the Cep OB2, Cyg OB3 and Cyg OB7 associations. The abundances are derived from spectrum synthesis, using both LTE and non-LTE calculations. As found in almost all previous studies of OB stars, the average abundances are slightly below solar, by about 0.1 to 0.3 dex. In the case of oxygen, even with the recently derived low solar abundances the OB stars are closer to, but still below, the solar value. Results for the 9 Cep OB2 members in this sample can be combined with results published previously for 8 Cep OB2 stars with low projected rotational velocities to yield the most complete set of abundances, to date, for this particular association. These abundances provide a clear picture of both the general chemical and individual stellar evolution that has occurred within this association. By placing the Cep OB2 stars studied in an HR diagram we identify the presence of two distinct age subgroups, with both subgroups having quite uniform chemical abundances. Two stars are found in the older subgroup that show significant N/O overabundances, with both stars being two of the most massive, the most evolved, and most rapidly rotating of the members studied in Cep OB2. These characteristics of increased N abundances being tied to high mass, rapid rotation, and an evolved phase are those predicted from models of rotating stars which undergo rotationally driven mixing.

description: Automatic detection of colonic polyps is still an unsolved problem due to the large variation of polyps in terms of shape, texture, size, and color, and the existence of various polyp-like mimics during colonoscopy. In this study, we apply a recent region based convolutional neural network (CNN) approach for the automatic detection of polyps in images and videos obtained from colonoscopy examinations. We use a deep-CNN model (Inception Resnet) as a transfer learning scheme in the detection system. To overcome the polyp detection obstacles and the small number of polyp images, we examine image augmentation strategies for training deep networks. We further propose two efficient post-learning methods such as, automatic false positive learning and off-line learning, both of which can be incorporated with the region based detection system for reliable polyp detection. Using the large size of colonoscopy databases, experimental results demonstrate that the suggested detection systems show better performance compared to other systems in the literature. Furthermore, we show improved detection performance using the proposed post-learning schemes for colonoscopy videos.

description: A group of Gemini quaternary ammonium surfactants with the formula CnH2n+1CONH(CH2)2N+(CH3)2(CH2)2N+(CH3)2(CH2)2NHCOCnH2n+1 · 2Y (n = 11, 13 and 15, Y = HCOO−, CH3COO− and CH3CHOHCOO−) have been synthesized by a counterion conversion process and characterized by a Fourier transform infrared spectroscopy and a mass spectroscopy. Their adsorption and self-aggregation properties are investigated by surface tension, conductivity, dynamic light scattering and transmission electron microscopy (TEM) measurements. The results show that these surfactants reduce the surface tension of water to a minimum value of 26.51 mN m−1 at a concentration of 5.72 × 10−2 mmol l−1. Furthermore, the increased alkyl chain length of the carboxylic counterions leads to the increased critical micelle concentration, the decreased degree of counterion binding (β) and the decreased self-assembly tendency, but the minimum area per surfactant molecule (Amin) adsorbed at the air–aqueous solution are similar. TEM images reveal that these surfactants self-assemble spontaneously into aggregates with vesicle or bilayer structures. It is also found that they have superior antibacterial activity at a concentration of 0.1 g l−1. The high surface activity and high antibacterial activity of the Gemini quaternary ammonium salt surfactants containing different carboxylic counterions bring more possibilities for the application in the field of biomedicine.

description: In this work, the transition form factors are calculated for the semileptonic $D_{(s)} \to A \ell^+ ν$ where $A=a_{1}, b_{1}, K_{1}(1270,1400)$, i.e., $D^{+} \to a^{0}_{1} (b^{0}_{1}, K^{0}_{1}) \ell^+ ν$, $D^{0} \to a^{-}_{1} (b^{-}_{1}) \ell^+ ν$, and $D^{+}_{s}\to K^{0}_{1} \ell^+ ν$ in the frame work of the light-cone QCD sum rules (LCSR) approach up to the twist-3 distribution amplitudes (DAs). Since the masses of these axial vector mesons are comparable to the charm quark mass, we keep out in our calculations all terms including ${m_{A}}/{m_c}$ in expansion of two--parton DAs. Branching ratio values are estimated for the semileptonic $D_{(s)} \to A \ell ν$ and nonleptonic $D\to K_1 (1270,1400) π$ decays. A comparison is also made between our results and predictions of other methods and the existing experimental values.

description: Introdução: A cirurgia bariátrica, procedimento eficaz para o tratamento da obesidade grave, apresenta desafios anestésicos significativos devido às alterações fisiológicas e anatômicas presentes nesses pacientes. O manejo anestésico adequado é crucial para garantir a segurança do paciente durante e após o procedimento. O manejo adequado da anestesia e da dor em cirurgias bariátricas é fundamental para o sucesso do procedimento e o bem-estar do paciente. Estas cirurgias, destinadas ao tratamento da obesidade mórbida, apresentam desafios específicos devido às características dos pacientes, que frequentemente possuem comorbidades associadas. Portanto, uma abordagem anestésica cuidadosa e uma estratégia eficaz de controle da dor são essenciais para minimizar riscos intraoperatórios e complicações pós-operatórias, promover uma recuperação mais rápida e melhorar a qualidade de vida dos pacientes. Objetivo: Identificar as melhores práticas anestésicas e de controle da dor para melhorar a segurança, eficácia e resultados clínicos em pacientes submetidos a cirurgias bariátricas. Metodologia: Foram utilizadas as bases de dados Cochrane, Scielo e Medline, buscando artigos publicados entre os anos de 2018 e 2024, nos idiomas Português ou Inglês. Considerações Finais: O manejo da anestesia e da dor em cirurgias bariátricas é vital para a segurança e o conforto dos pacientes. Portanto, a combinação de anestesia geral com bloqueios regionais pode diminuir os riscos respiratórios e cardiovasculares. Além disso, um controle eficiente da dor pós-operatória, através do uso combinado de analgésicos opioides e não opioides, acelera a recuperação e reduz complicações. Assim, personalizar essas abordagens de acordo com as características individuais dos pacientes é crucial para otimizar os resultados e melhorar a qualidade de vida no pós-operatório.

The Case of H$_2$C$_3$O Isomers, Revisited: Solving the Mystery of the Missing Propadienone

description: To date, two isomers of H$_2$C$_3$O have been detected, namely, propynal (HCCCHO) and cylclopropenone (c-H$_2$C$_3$O). A third, propadienone (CH$_2$CCO), has thus far eluded observers despite the fact that it is the lowest in energy of the three. This previously noted result is in contradiction of the minimum energy principle, which posits that the abundances of isomers in interstellar environments can be predicted based on their relative stabilities - and suggests, rather, the importance of kinetic over thermodynamic effects in explaining the role of such species. Here, we report results of \textit{ab initio} quantum chemical calculations of the reaction between H and (a) HC$_3$O, (b) H$_2$C$_3$O (both propynal and propadienone), and (c) CH$_2$CHCO. We have found that, among all possible reactions between atomic hydrogen and either propadienone or propynal, only the destruction of propadienone is barrierless and exothermic. That this destruction pathway is indeed behind the non-detection of CH$_2$CCO is further suggested by our finding that the product of this process, the radical CH$_2$CHCO, can subsequently react barrierlessly with H to form propenal (CH$_2$CHCHO) which has, in fact, been detected in regions where the other two H$_2$C$_3$O isomers are observed. Thus, these results not only shed light on a previously unresolved astrochemical mystery, but also further highlight the importance of kinetics in understanding the abundances of interstellar molecules.

description: We describe a Faraday-rotation structure in the Interstellar Medium detected through polarimetric imaging at 1420 MHz from the Canadian Galactic Plane Survey (CGPS). The structure, at l=91.8, b=-2.5, has an extent of ~2 degree, within which polarization angle varies smoothly over a range of ~100 degree. Polarized intensity also varies smoothly, showing a central peak within an outer shell. This region is in sharp contrast to its surroundings, where low-level chaotic polarization structure occurs on arcminute scales. The Faraday-rotation structure has no counterpart in radio total intensity, and is unrelated to known objects along the line of sight, which include a Lynds Bright Nebula, LBN 416, and the star cluster M39 (NGC7092). It is interpreted as a smooth enhancement of electron density. The absence of a counterpart, either in optical emission or in total intensity, establishes a lower limit to its distance. An upper limit is determined by the strong beam depolarization in this direction. At a probable distance of 350 +/- 50 pc, the size of the object is 10 pc, the enhancement of electron density is 1.7 cm-3, and the mass of ionized gas is 23 M_sun. It has a very smooth internal magnetic field of strength 3 microG, slightly enhanced above the ambient field. G91.8-2.5 is the second such object to be discovered in the CGPS, and it seems likely that such structures are common in the Magneto-Ionic Medium.

description: Spin waves are promising information carriers which can be used in modern magnonic devices, characterized by higher performance and lower energy consumption than presently used electronic circuits. However, before practical application of spin waves, the efficient control over spin wave amplitude and phase needs to be developed. We analyze analytically reflection and refraction of the spin waves at the interface between two ferromagnetic materials. In the model we consider the system consisting of two semi-infinite ferromagnetic media, separated by the ultra-narrow interface region with the magnetic anisotropy. We have found the Goos-Hanchen shift for spin waves in transmission and reflection, and performed detailed investigations of its dependence on the anisotropy at the interface and materials surrounding the interface. We have demonstrated possibility of obtaining Goos-Hanchen shift of several wavelengths in reflection for realistic material parameters. That proves the possibility for change of the spin waves phase in ferromagnetic materials at subwavelength distances, which can be regarded as a metasurface for magnonics.
