description: In this article we compare the well-known Ramsey property with a dual form of it, the so called dual-Ramsey property (which was suggested first by Carlson and Simpson). Even if the two properties are different, it can be shown that all classical results known for the Ramsey property also hold for the dual-Ramsey property. We will also show that the dual-Ramsey property is closed under a generalized Suslin operation (the similar result for the Ramsey property was proved by Matet). Further we compare two notions of forcing, the Mathias forcing and a dual form of it, and will give some symmetries between them. Finally we give some relationships between the dual-Mathias forcing and the dual-Ramsey property.
Tetrahedral intrinsic structure of Oxygen-16 revisited

description: Abstract: A model for vibrational and rotational excitations of an intrinsic tetrahedral structure of the Oxygen-16 nucleus has been investigated, building on classic work of Wheeler, Dennison and Robson. Tetrahedral A- and F-phonons are treated harmonically, but the E-phonon dynamics is extended to dynamics on an E-manifold of configurations of four α-particles. This allows for tunnelling between the tetrahedral configuration and its dual, through a square configuration, and lifts the parity doubling that would otherwise occur. Unlike in earlier models, including the algebraic cluster model, the E-phonon frequency is taken to be about half the F-phonon frequency, which in turn is about half the A-phonon frequency. As a result, the first-excited 0+ state is a 2-phonon, E-manifold excitation, whereas the lowest 2+ and 2− states are 1-phonon, E-manifold excitations. Coriolis contributions to the rotational energy of states with F-phonons are significant. Altogether, rotational bands are constructed based on vibrational states with up to four phonons, and with spin/parity up to 9−. Nearly all the observed states of Oxygen-16 are accommodated, up to 20 MeV and partly beyond. Predictions for some so far unobserved states, especially those of unnatural parity, are made.

Iridomyrmex obscurans

description: Iridomyrmex obscurans Carpenter, incertae sedis
 Iridomyrmex obscurans Carpenter, 1930: 51.
 Types. Holotype queen from the United States (Oligocene).
 Comments. When describing this species Carpenter (1930) commented that it “is one of the most obscure of the Florissant ants, since nothing but the more general features are known”. Unfortunately little has changed over the past 90 years and this species remains essentially unknown. While there is little rigorous data to suggest it belongs in Iridomyrmex, placement in another genus would be just as tenuous and therefore it remains in Iridomyrmex as incertae sedis.

description: The solution for the nucleon-nucleon T matrix in the framework of the covariant Bethe-Salpeter approach for a two spin-one-half particle system with a separable kernel of interaction is analyzed. The explicit analytical connection between parameters of the separable kernel and low energy scattering parameters, deuteron binding energy and phase shifts is established.Covariant separable kernels for positive-energy partial channels with total angular momentum J=0 (1S0+, 3P0+) and J=1 (3S1+-3D1+, 1P1+, 3P1+) are constructed by using obtained relations.

description: Rings and spiral arms are distinctive features of many galaxies, and their properties are closely related to the disk dynamics. They are often associated to stellar bars, but the details of this connection are far from clear. We study the pitch angles of spiral arms and the frequency and dimensions of inner and outer rings as a function of disk parameters and the amplitude of non-axisymmetries in the S$^4$G survey. The ring fraction increases with bar Fourier density amplitude: this can be interpreted as evidence for the role of bars in ring formation. The sizes of inner rings, normalised by the disk size, are positively correlated with bar strength: this can be linked to the radial displacement of the inner 4:1 ultra-harmonic resonance while the bar grows and the pattern speed decreases. The fraction of rings is larger in barred galaxies than in their non-barred counterparts, but still $\sim 1/3$ ($\sim 1/4$) of the galaxies hosting inner (outer) rings are not barred. The amplitudes of bars and spirals are correlated for all types of spirals. However, on average, the pitch angles of spiral arms are roughly the same for barred and non-barred galaxies: this questions the role of bars exciting spiral structure. We conclude that the present-day coupling of rings, spiral arms, and bars is not as robust as predicted by simulations.

Iridomyrmex shandongicus

description: Iridomyrmex shandongicus Zhang
 Iridomyrmex shandongicus Zhang, 1989: 278.
 Types. Holotype queen from China (Miocene).
 Comments. Of all the fossils thus far placed within Iridomyrmex, this is the only one with strong support. While Zhang’s (1989) figures are simple line drawings with minimal detail, the shape of the mandibles as well as the wing venation is consistent with extant species within the genus. Critical details such as the configuration of the anterior clypeal margin are unfortunately missing, and the location of the compound eye is slightly anterior of what might be expected, but in general, the placement of this species within Iridomyrmex seems plausible and is accepted in this study.

description: We report Cd NMR and Re NQR studies on Cd2Re2O7, the first superconductor among pyrochlore oxides Tc=1 K. Re NQR spectrum at zero magnetic field below 100 K rules out any magnetic or charge order. The spin-lattice relaxation rate below Tc exhibits a pronounced coherence peak and behaves within the weak-coupling BCS theory with nearly isotropic energy gap. Cd NMR results point to moderate ferromagnetic enhancement at high temperatures followed by rapid decrease of the density of states below the structural transition temperature of 200 K.

description: Two indicators were used: the economic subsistence level (ESL) where annual income equaled expenditure and a nutritional poverty line (NPL) where average annual total income equaled the estimated taka cost of an acceptable nutritional diet per average household for each size grouping. Across three sampler reviewed in detail, 22% of the total sample of 135 farmers were below the ESL and 16 % below the NPL. A further 15% were around the ESL and 5% around the NPL. These figures appeared to be much lower estimates dun those found by others. The main difference was that the data for this study were collected from weekly monitoring over the whole duration of the season/year and hence should have been more accurate than the cross sectional data used in other studies.

description: The energy spectra and quantum diffusion of an electron in a 1D incommensurate Frenkel-Kontorova (FK) model are studied numerically. We found that the spectral and dynamical properties of electron display quite different behaviors in invariance circle regime and in Cantorus regime. In the former case, it is similar to that of the Harper model, whereas in the latter case, it is similar to that of the Fibonacci model. The relationship between spectral and transport properties is discussed.

description: This study provides useful information on the
existing interactions in an aqueous solution of deep eutectic
solvents (DESs) by studying excess properties namely excess refractive index and excess logarithm viscosity at different concentrations and temperatures. In order to investigate the effects of DES mole fraction and temperature on the refractive index and viscosity of binary mixtures, the response surface methodology (RSM) was applied based on the mixed-level full factorial design. The analysis of variance (ANOVA) results revealed that although both DES mole fraction and temperature are significant, the DES mole fraction has more effect on these thermophysical properties. Results showed that as excess refractive index and excess logarithm viscosity values are positive over the whole composition range and maximum excess data were
investigated at the water-reach region. Moreover, the effects of important factors influencing CO2 solubilities such as pressure,
temperature, water content, and molecular weight of DES were determined using the Taguchi L18 method. A regression model was
developed based on the Taguchi method for prediction of the prediction of CO2 solubility. The results disclosed that the pressure is
the most significant factor influencing the CO2 fraction followed by the water content and molecular weight of DESs while the
temperature had the lowest effect. The error evaluations indicated that the Taguchi model is an accurate model and had excellent
performance in prediction of the CO2 solubility.

description: Effects of the electron-electron interaction in the two-dimensional flux phase are investigated. We treat the half-filled Hubbard model with a magnetic flux $π$ per plaquette by the quantum Monte Carlo method. When the interaction is small, an antiferromagnetic long-range does not exist and the charge fluctuation is different from that of the Mott insulator It suggests that the Mott transition occurs at finite strength of the interaction in the flux phase, which is in contrast to the standard Hubbard model.

description: Analysis of data from a village of Bangladesh shows that the incomes of poor and landless households are inadequate to meet their minimum basic needs and particularly the landless households mostly depend on gifts and loans for their mere survival. The need for credit is seriously felt by the poor farmers during born season which they meet mostly by borrowing from non-institutional sources at a very high interest rate and by mortgaging out land. Timely supply of credit at subsidized interest rate, input subsidy and ensured fair output price would improve the condition of the poor farmers. WI He for landless, since the prospect to get substantial benefit from new technology is not so bright (even if labour inte7sive technologies are adopted), particularly due to shifting of traditional peak periods of labour demand to new peak periods ; substantial credit and institutional support to create non-farm income generating activities would their condition.

description: We investigate families of partitions of omega which are related to special coideals, so-called happy families, and give a dual form of Ramsey ultrafilters in terms of partitions. The combinatorial properties of these partition-ultrafilters, which we call Ramseyan ultrafilters, are similar to those of Ramsey ultrafilters. For example it will be shown that dual Mathias forcing restricted to a Ramseyan ultrafilter has the same features as Mathias forcing restricted to a Ramsey ultrafilter. Further we introduce an ordering on the set of partition-filters and consider the dual form of some cardinal characteristics of the continuum.

description: Mass-spectrometry technologies are widely used in the fields of ionomics and metabolomics to simultaneously profile at the genome scale intracellular concentrations of e.g. amino acids or elements. Short profiles of molecular or sub-molecular features are intrinsically non-Gaussian and may reveal patterns of correlations that reflect the system nature of the cell biochemistry and biology. Here we introduce two profile similarity measures that enforce information from the empirical covariance matrix of the data, the Mahalanobis cosine and the hybrid-Mahalanobis cosine. We evaluate the performance of these similarity measures in the task of inferring and integrating genetic networks from omics data by analysing experimental datasets derived from the ionome and the metabolome of the model organism S. cerevisiae, and several large curated databases of genetic annotations. The proposed covariance-based similarity measures can in general recover known and predicted associations between genes better than the commonly used Pearson's correlation and the standard cosine similarity. The choice of which of the two measures to recommend depends upon whether the focus is on extracting genetic associations at a global or local genetic network scale.

description: Non-repayment of bank loans and rental charges for irrigation equipment is widespread in Bangladesh. Owners/managers of equipment, who are largely rich farmers, do not repay loans or rentals inspite of their large profits accumulated from increased production and water sales. This paper illustrates with field level evidence that the underlying causes of non-repayment are bureaucratic and political inefficiencies associated with allocation and installation of equipment, distribution of loan and provision of support services.

description: This paper has attempted to measure the extent and level of faun household income surpluses and the magnitude of potential investible capital. Patterns of investment of the selected farm families and factors affecting their investment choices also were analysed. For analytical purposes, sample farmers were categorised into four farm size groups. Findings of the study revealed that in rural areas of Bangladesh farm families operating between I acre to 2.5 acres of land could be considered as potential for mobilization of income surpluses. Medium and large farms exhibited substantial positive income surpluses. Investment analysis showed that investment on land purchase and on non-agricultural purposes was highest for the large farms. Smaller farms invested more for improvement of their land resource and on acquisition of livestock resources. This study indicated that the very small farms in particular and some other small farms upto 2.00 acres of operational holding in general require external financing for pursuing productive investment.

description: Anonychomyrma geinitzi (Mayr), comb. nov.
 Hypoclinea geinitzi Mayr, 1868: 58.
 Types. Syntype workers, queens and males from Baltic amber (Eocene).
 Comments. This species was moved from Hypoclinea to Bothriomyrmex by Dalla Torre (1893) and then to Iridomyrmex by Wheeler (1915b), a position supported by Shattuck (1992a) and Dlussky (1997). Dlussky (1997), in a study of Baltic amber ants, provides a key to genera of ants occurring in this amber, where he states that the anterior margin of the clypeus in Iridomyrmex has a “small medial lobe projecting forwards”. However, his illustration of the head of H. geinitzi (fig. 2e) clearly shows the anterior clypeal margin as being uniformly convex and not with the anteromedial clypeal prominence characteristic of typical Iridomyrmex. Additionally, the eyes (based on fig. 2e) are placed more anteriorly and laterally on the head compared to extant Iridomyrmex, where they are typically positioned more medially and posteriorly. It seems clear that this species does not belong to Iridomyrmex, but rather to Anonychomyrma, as the head is typical of that genus. The body (based on Dlussky’s (1997) fig. 2d) is slightly more elongate than typical extant Anonychomyrma, but not unduly and approaches the morphology seen in some Papua New Guinean species of the genus. Because of this, this species is here transferred from Iridomyrmex to Anonychomyrma (noting the geographic distribution of the genus as discussed above).

description: Random matrix theory has proven very successful in the understanding of the spectra of chaotic systems. Depending on symmetry with respect to time reversal and the presence or absence of a spin 1/2 there are three ensembles, the Gaussian orthogonal (GOE), Gaussian unitary (GUE), and Gaussian symplectic (GSE) one. With a further particle-antiparticle symmetry the chiral variants of these ensembles, the chiral orthogonal, unitary, and symplectic ensembles (the BDI, AIII, and CII in Cartan's notation) appear. A microwave study of the chiral ensembles is presented using a linear chain of evanescently coupled dielectric cylindrical resonators. In all cases the predicted repulsion behavior between positive and negative eigenvalues for energies close to zero could be verified.

description: A microscopic calculation of near-threshold eta-meson production in the reaction NN -> NNeta is presented. It is assumed that the eta meson is produced via direct emission and via elementary rescattering processes MN -> etaN of various mesons M = pi, rho, etc. As a novel feature the amplitudes for the latter production mechanism are taken from a multi-channel meson-exchange model of the pi N system developed by the Juelich group which contains explicitly the channels pi N, rho N, eta N, sigma N, and pi Delta. Furthermore, effects of the NN interaction in the final as well as in the initial state are taken into account microscopically. Our results are compared with recent data from the COSY and CELSIUS accelerator facilities. Reasonable agreement with available near-threshold cross section data for the reactions pp -> ppeta, pn -> pneta, and pn -> deta is found.

description: Effective String Theory (EST) represents a powerful non-perturbative approach to describe confinement in Yang-Mills theory that models the confining flux tube as a thin vibrating string. EST calculations are usually performed using the zeta-function regularization: however there are situations (for instance the study of the shape of the flux tube or of the higher order corrections beyond the Nambu-Goto EST) which involve observables that are too complex to be addressed in this way. In this paper we propose a numerical approach based on recent advances in machine learning methods to circumvent this problem. Using as a laboratory the Nambu-Goto string, we show that by using a new class of deep generative models called Continuous Normalizing Flows it is possible to obtain reliable numerical estimates of EST predictions.

description: PurposeThough anger as an emotion is an important determinant of negotiation outcomes, the extant literature presents mixed and contradictory findings. We propose that the effect of anger in intercultural negotiations depends on the power and personality orientation of the counterpart negotiators.Design/methodology/approachBased on data from 429 working professionals in the USA, we conducted two experimental studies in which they responded to an angry Chinese counterpart.FindingsWe find that the intercultural negotiation outcomes depend on the three-way interaction between anger, power and personality orientation. Our findings suggest that US action-oriented negotiators conceded more in a high-power condition than in a low-power condition while responding to an angry Chinese counterpart, while US state-oriented negotiators showed no difference in concession size regardless of their power and counterpart’s anger.Originality/valueOur work is unique in establishing three-way interactive effects of power, personality and emotions in intercultural negotiation outcome relationships. Our findings are specific to an intercultural negotiation context consisting of negotiators from low-status, low-power-distance countries (e.g. the USA) with their counterparts from high-status, high-power-distance countries (e.g. China).

description: Little is known about which factors account for dynamic change or for stagnation in India's agriculture. Though statistics at the macro-economic level suggest upward trends, not much is known at the micro level to point to a rational explanation of these changes. On the other hand, successful macro-economic policies require a knowledge of economic decision-making processes at the farm level. As a contribution to meeting this need this micro-economic study, based on 85 farms over a six-year period, was undertaken in East India. It is an empirical attempt to understand the decision-making processes of East Indian farm households, classified by farm size. The study is based on detailed cost accounting records and, using statistical sampling techniques, important planning implications for East Indian agriculture and its development are drawn. Those concerned with growth of agricultural economy in a developing country may also find interesting the method and approach used in the study.

description: We applied the recently developed technique of force-detected nuclear magnetic resonance (NMR) to observe 71Ga, 69Ga, and 75As in GaAs. The nuclear spin-lattice relaxation time is 21$\pm$5 min for 69Ga at $\sim 5$ K and 4.6 Tesla. We have exploited this long relaxation time to first create and then observe spatially varying nuclear spin polarization within the sample, demonstrating a new form of contrast for magnetic resonance force microscopy (MRFM). Such nuclear spin contrast could be used to indirectly image electron spin polarization in GaAs-based spintronic devices.

description: Giant emitters derive their name from nonlocal field-emitter interactions and feature diverse self-interference effects. Most of the existing works on giant emitters have considered Hermitian waveguides or photonic lattices. In this work, we unveil how giant emitters behave if they are coupled to a non-Hermitian bath, i.e., a Hatano-Nelson (HN) model which features a non-Hermitian skin effect due to the asymmetric inter-site tunneling rates. We show that the behaviors of the giant emitters are closely related to the stability of the bath. In the convectively unstable regime, where the HN model can be mapped to a pseudo-Hermitian lattice, a giant emitter can either behave as in a Hermitian bath or undergo excitation amplification, depending on the relative strength of different emitter-bath coupling paths. Based on this mechanism, we can realize protected nonreciprocal interactions between giant emitters, with nonreciprocity opposite to that of the bath. Such giant-emitter effects are not allowed, however, if the HN model enters the absolutely unstable regime, where the coupled emitters always show secular energy growth. Our proposal provides a new paradigm of non-Hermitian quantum optics, which may be useful for, e.g., engineering effective interactions between quantum emitters and performing many-body simulations in the non-Hermitian framework.

description: Anonychomyrma constricta (Mayr)
 Hypoclinea constricta Mayr, 1868: 60.
 Types. Holotype worker from Baltic amber (Eocene).
 Comments. This species was transferred from Hypoclinea to Bothriomyrmex by Dalla Torre (1893), then to Iridomyrmex by Wheeler (1915b) and finally to Anonychomyrma by Shattuck (1992a), this final treatment being accepted by Dlussky (1997). It should be noted, however, that extant species of Anonychomyrma are restricted to Indonesia, Papua New Guinea, Australia and the Solomon Islands (Shattuck, 1992a, 1992b; Ward et al., 2010) while this and other fossil species currently placed in Anonychomyrma are well outside this geographic area. The possibility that these species would be better placed in a genus other than Anonychomyrma, probably newly erected specifically for them, cannot be ruled out.

description: Two-Photon Laser-Scanning Microscopy is a powerful tool for exploring biological structure and function because of its ability to optically section through a sample with a tight focus. While it is possible to obtain 3D image stacks by moving a stage, this perframe imaging process is time consuming. Here, we present a method for an easy to implement and inexpensive modification of an existing two-photon microscope to rapidly image in 3D using an electrically tunable lens to create a tessellating scan pattern which repeats with the volume rate. Using appropriate interpolating algorithms, the volumetric imaging rate can be increased by a factor up to four-fold. This capability provides the expansion of the two-photon microscope into the third dimension for faster volumetric imaging capable of visualizing dynamics on timescales not achievable by traditional stage stack methods.

description: In this paper, we propose and analyze high order efficient schemes for the time fractional Allen-Cahn equation. The proposed schemes are based on the L1 discretization for the time fractional derivative and the extended scalar auxiliary variable (SAV) approach developed very recently to deal with the nonlinear terms in the equation. The main contributions of the paper consist in: 1) constructing first and higher order unconditionally stable schemes for different mesh types, and proving the unconditional stability of the constructed schemes for the uniform mesh; 2) carrying out numerical experiments to verify the efficiency of the schemes and to investigate the coarsening dynamics governed by the time fractional Allen-Cahn equation. Particularly, the influence of the fractional order on the coarsening behavior is carefully examined. Our numerical evidence shows that the proposed schemes are more robust than the existing methods, and their efficiency is less restricted to particular forms of the nonlinear potentials.

description: Medical imaging is a key component in clinical diagnosis, treatment planning and clinical trial design, accounting for almost 90% of all healthcare data. CNNs achieved performance gains in medical image analysis (MIA) over the last years. CNNs can efficiently model local pixel interactions and be trained on small-scale MI data. The main disadvantage of typical CNN models is that they ignore global pixel relationships within images, which limits their generalisation ability to understand out-of-distribution data with different 'global' information. The recent progress of Artificial Intelligence gave rise to Transformers, which can learn global relationships from data. However, full Transformer models need to be trained on large-scale data and involve tremendous computational complexity. Attention and Transformer compartments (Transf/Attention) which can well maintain properties for modelling global relationships, have been proposed as lighter alternatives of full Transformers. Recently, there is an increasing trend to co-pollinate complementary local-global properties from CNN and Transf/Attention architectures, which led to a new era of hybrid models. The past years have witnessed substantial growth in hybrid CNN-Transf/Attention models across diverse MIA problems. In this systematic review, we survey existing hybrid CNN-Transf/Attention models, review and unravel key architectural designs, analyse breakthroughs, and evaluate current and future opportunities as well as challenges. We also introduced a comprehensive analysis framework on generalisation opportunities of scientific and clinical impact, based on which new data-driven domain generalisation and adaptation methods can be stimulated.

description: The new generation of galaxy surveys will provide unprecedented data allowing us to test gravity at cosmological scales. A robust cosmological analysis of the large-scale structure demands exploiting the nonlinear information encoded in the cosmic web. Machine Learning techniques provide such tools, however, do not provide a priori assessment of uncertainties. This study aims at extracting cosmological parameters from modified gravity (MG) simulations through deep neural networks endowed with uncertainty estimations. We implement Bayesian neural networks (BNNs) with an enriched approximate posterior distribution considering two cases: one with a single Bayesian last layer (BLL), and another one with Bayesian layers at all levels (FullB). We train both BNNs with real-space density fields and power-spectra from a suite of 2000 dark matter only particle mesh $N$-body simulations including modified gravity models relying on MG-PICOLA covering 256 $h^{-1}$ Mpc side cubical volumes with 128$^3$ particles. BNNs excel in accurately predicting parameters for $Ω_m$ and $σ_8$ and their respective correlation with the MG parameter. We find out that BNNs yield well-calibrated uncertainty estimates overcoming the over- and under-estimation issues in traditional neural networks. We observe that the presence of MG parameter leads to a significant degeneracy with $σ_8$ being one of the possible explanations of the poor MG predictions. Ignoring MG, we obtain a deviation of the relative errors in $Ω_m$ and $σ_8$ by at least $30\%$. Moreover, we report consistent results from the density field and power spectra analysis, and comparable results between BLL and FullB experiments which permits us to save computing time by a factor of two. This work contributes in setting the path to extract cosmological parameters from complete small cosmic volumes towards the highly nonlinear regime.

description: The spiral edge-on galaxies from the "Revised Flat Galaxy Catalog" (RFGC) are identified with the Extended Source Catalog of the Two Micron All Sky Survey (2MASS). A relative number of the 2MASS detected galaxies is 2996/4236 = 0.71. We consider the statistical properties of the Tully-Fisher relations for the edge-on galaxies in the B, I, J, H, and K_s bands. The slope of derived TF relations increases steadily from 4.9 in the B band to 9.3 in the K one. The effect is mainly due to the internal extinction which is different in dwarf and giant spiral galaxies seen edge-on that leads to the tight correlation between galaxy color and luminosity. The moderate scatter of the RFGC galaxies in the `color-luminosity' diagram, 0.86 mag., provides us with a new "cheap" method of mass measurements of distances to galaxies on the basis of modern photometric sky surveys.
