description: One possible diagnostic of planet formation, orbital migration, and tidal evolution is the angle psi between a planet's orbital axis and the spin axis of its parent star. In general, psi cannot be measured, but for transiting planets one can measure the angle lambda between the sky projections of the two axes via the Rossiter-McLaughlin effect. Here, we show how to combine measurements of lambda in different systems to derive statistical constraints on psi. We apply the method to 11 published measurements of lambda, using two different single-parameter distributions to describe the ensemble. First, assuming a Rayleigh distribution (or more precisely, a Fisher distribution on a sphere), we find that the peak value is less than 22 degrees with 95% confidence. Second, assuming a fraction f of the orbits have random orientations relative to the stars, and the remaining fraction (1-f) are perfectly aligned, we find f<0.36 with 95% confidence. This latter model fits the data better than the Rayleigh distribution, mainly because the XO-3 system was found to be strongly misaligned while the other 10 systems are consistent with perfect alignment. If the XO-3 result proves robust, then our results may be interpreted as evidence for two distinct modes of planet migration.

description: We propose a new method to measure the absolute photon absorption cross section of neutral molecules in a molecular beam. It is independent of our knowledge of the particle beam density, nor does it rely on photo-induced fragmentation or ionization. The method is based on resolving the recoil resulting from photon absorption by means of near-field matter-wave interference, and it thus applies even to very dilute beams with low optical densities. Our discussion includes the possibility of internal state conversion as well as fluorescence. We assess the influence of various experimental uncertainties and show that the measurement of absolute absorption cross sections is conceivable with high precision and using existing technologies.

description: In multi-turn dialogues, large language models (LLM) face a critical challenge of ensuring coherence while adapting to user-specific information. This study introduces the persona knowledge gap, the discrepancy between a model's internal understanding and the knowledge required for coherent, personalized conversations. While prior research has recognized these gaps, computational methods for their identification and resolution remain underexplored. We propose Conversation Preference Elicitation and Recommendation (CPER), a novel framework that dynamically detects and resolves persona knowledge gaps using intrinsic uncertainty quantification and feedback-driven refinement. CPER consists of three key modules: a Contextual Understanding Module for preference extraction, a Dynamic Feedback Module for measuring uncertainty and refining persona alignment, and a Persona-Driven Response Generation module for adapting responses based on accumulated user context. We evaluate CPER on two real-world datasets: CCPE-M for preferential movie recommendations and ESConv for mental health support. Using A/B testing, human evaluators preferred CPER's responses 42% more often than baseline models in CCPE-M and 27% more often in ESConv. A qualitative human evaluation confirms that CPER's responses are preferred for maintaining contextual relevance and coherence, particularly in longer (12+ turn) conversations.

description: The present paper is a continuation of a foregoing paper [Tensor, N. S., 69 (2008), 155-178]. The main aim is to establish \emph{an intrinsic investigation} of the conformal change of the most important special Finsler spaces, namely, $C^{h}$-recurrent, $C^{v}$-recurrent, $C^{0}$-recurrent, $C_{2}$-like, quasi-$C$-reducible, $C$-reducible, Berwald space, $S^{v}$-recurrent, $P^*$-Finsler manifold, $R_{3}$-like, $P$-symmetric, Finsler manifold of $p$-scalar curvature and Finsler manifold of $s$-$ps$-curvature. Necessary and sufficient conditions for such special Finsler manifolds to be invariant under a conformal change are obtained. Moreover, the conformal change of Chern and Hashiguchi connections, as well as their curvature tensors, are given.

A capillaroscopic investigation of mongolism
Creators: name: Shalman, Denis Clarence
Publisher: name: University of British Columbia
Year: 2012

description: The purpose of the study was to determine the morphological capillary pattern of the mongoloids and compare this with another constitutionally retarded clincial group - the phenylketonurics- and the degree of deviation from the "normal" pattern. Photomicrographs were taken with capillary microscope and the capillaries were analysed into the ten basic morphological categories as set out by Gibson, Bosley and Griffiths (1956). It was concluded that the mongoloids and the phenylketonurics differed significantly in the amount of primitive immature configuration they displayed. The hypothesis of Powdermaker (1929) that structure is related to function, was found tenable through a capillaroscopic examination of scholastically retarded school children.

description: Agricultural productivity is significantly hindered by the limited availability of phosphorus in acidic soils due to the presence of aluminum and iron phosphates. Soil liming is commonly employed to enhance soil fertility. However, modifying the pH might also impact the interactions involving existing soil organic matter, leading to changes in the effective concentrations of competing low-molecular-weight acids (LMWOACs) participating in phosphorus adsorption. This study explored the impacts of citric, oxalic, and malic acids in acidic soils from tea cultivation regions within the Eastern Black Sea. These soils had undergone various levels of liming and were incubated for 15 months to assess their effects on phosphorus (P) adsorption in 7 acidic soils. The experimental sorption data were utilized to calculate the soil Langmuir and Freundlich adsorption parameters. In addition, the influences of organic acids and liming levels on the Freundlich and Langmuir model parameters were subjected to ANOVA analysis. The findings indicated that citric acid demonstrated the highest efficiency in diminishing phosphorus adsorption among the tested organic acids, followed by oxalic and malic acids. Three carboxyl groups (−COOH) in citric acid facilitated the formation of more complexes with adsorbed phosphorus on the soil surface. Furthermore, the 100% LR ratio of liming notably decreased phosphorus adsorption, especially in the lower end of the isotherms. Therefore, it can be concluded that the combination of LMWOACs and liming treatments could be used to overcome P deficiency in acid soils with very high P sorption ability.

description: This paper presents the study and the realization at IETR of a high data rate 60 GHz wireless communications system. The system uses a simple single carrier architecture. The receiver architecture is based on a differential demodulation which minimizes the intersymbol interference (ISI) effect and a signal processing unit composed of a joint frame and byte synchronization block and a conventional RS (255, 239) decoder. The byte synchronization technique provides a high preamble detection probability and a very small value of the false detection probability. First measurement results show a good communication link quality in line of sight environments with directional antennas.

A Graph-Matching Approach for Cross-view Registration of Over-view 2 and Street-view based Point Clouds

Publisher: name: arXiv
Year: 2022
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: In this paper, based on the assumption that the object boundaries (e.g., buildings) from the over-view data should coincide with footprints of façade 3D points generated from street-view photogrammetric images, we aim to address this problem by proposing a fully automated geo-registration method for cross-view data, which utilizes semantically segmented object boundaries as view-invariant features under a global optimization framework through graph-matching: taking the over-view point clouds generated from stereo/multi-stereo satellite images and the street-view point clouds generated from monocular video images as the inputs, the proposed method models segments of buildings as nodes of graphs, both detected from the satellite-based and street-view based point clouds, thus to form the registration as a graph-matching problem to allow non-rigid matches; to enable a robust solution and fully utilize the topological relations between these segments, we propose to address the graph-matching problem on its conjugate graph solved through a belief-propagation algorithm. The matched nodes will be subject to a further optimization to allow precise-registration, followed by a constrained bundle adjustment on the street-view image to keep 2D29 3D consistencies, which yields well-registered street-view images and point clouds to the satellite point clouds.

description: Salinity is a major abiotic stressor that can significantly impact plant growth and productivity. To evaluate the physiological responses of sweet pepper (Capsicum annuum L. Ps301) to gradual salinity stress (SLS) and shock salinity stress (STS), an experiment was conducted using a factorially based completely randomized design (CRD). The sodium chloride (NaCl) induced salinity treatments were administered in the nutrient solution in two forms: STS and SLS. The SLS was applied for 8 days, with stress levels increasing every 2 days; STS was administered for 48 h. The signaling response was activated more rapidly and abruptly in response to STS; however, after the various adaptive responses to salinity, these signals were more activated in response to SLS. The STS led to plant growth a greater decrease than SLS. The electrolyte leakage (EL) increased under both SLS and STS by 60% and 61% compared to the control, respectively. Other stress indices, such as phenol and abscisic acid (ABA) content, increased by 26% and 71% under SLS compared to STS. Salinity increased the leaf water potential (LWP) in two salt regimes, and the root water potential (RWP) in STS conditions only. Salinity stress decreased plasma membrane intrinsic protein gene expression in roots, especially in STS compared to SLS. The STS increased plasma membrane intrinsic protein (PIP) expression in leaves more than SLS. It was concluded that salinity impairs the growth and physiological characteristics of pepper; however, the signaling and stress indices respond differently to STS and SLS application.
Correlated earthquakes in a self-organized model

description: Motivated by the fact that empirical time series of earthquakes exhibit long-range correlations in space and time and the Gutenberg-Richter distribution of magnitudes, we propose a simple fault model that can account for these types of scale-invariance. It is an avalanching process that displays power-laws in the event sizes, in the epicenter distances as well as in the waiting-time distributions, and also aftershock rates obeying a generalized Omori law. We thus confirm that there is a relation between temporal and spatial clustering of the activity in this kind of models. The fluctuating boundaries of possible slipping areas show that the size of the largest possible earthquake is not always maximal, and the average correlation length is a fraction of the system size. This suggests that there is a concrete alternative to the extreme interpretation of self-organized criticality as a process in which every small event can cascade to an arbitrary large one: the new picture includes fluctuating domains of coherent stress field as part of the global self-organization. Moreover, this picture can be more easily compared with other scenarios discussing fluctuating correlations lengths in seismicity.

description: The Perceived Relationship Superiority Effect (PRSE) highlights that many people consider their own romantic relationship better than others’ romantic relationships (e.g., Buunk & van der Eijnden, 1997; Reis et al., 2011). But initial data indicate that exposure to positive images of others’ romantic relationship (as common on social networking sites such as Instagram) can elicit spontaneous relationship comparisons and undermine viewers’ attitudes towards their own relationship (cf. Thai et al., 2020). This two-part study therefore investigates whether and how exposure to other people’s positive romantic relationship images affects the PRSE.

description: Since its first experimental demonstration, “ghost imaging” has attracted much attention, perhaps not only because of its interesting physics but also because of its attractive application. This review article discusses the physics and application of ghost imaging: (1) emphasizes the nonlocal two-photon interference nature of ghost imaging, including detailed analysis and calculations; (2) introduces three types of applications with unique advantages of ghost imaging, including a light detection and ranging device with imaging ability, namely, an Imaging Lidar or ILidar system; a turbulence-resistant, or turbulence-free, imaging technology; and a vibration-resistant X-ray microscope of high resolving capability. This article is prepared for a Special Issue of Chinese Optics Letters, intended for general audiences, especially young researchers and students who are interested in ghost imaging.

Studies on the biosynthesis of nucleic acids by Novikoff hepatoma tissue in vitro
Creators: name: Scrimgeour, Kenneth Gray
Publisher: name: University of British Columbia
Year: 2012

description: Nucleic acid metabolism has been studied in vitro with suspensions of Novikoff rat hepatoma cells. The formation of acid soluble and nucleic acid purines from formate-C¹⁴ and adenine-8-C¹⁴ has been measured. In all cases, adenine had a higher specific activity than guanine. The acid soluble purines were much more radioactive than the nucleic acid purines. Adenine-8-C¹⁴ gave a higher value for the ratio of the specific activities of adenine to guanine nucleotides than that obtained from formate-C¹⁴. Both ribonucleic acid and deoxyribonucleic acid incorporated radioactivity in this system. A standardized set of conditions suitable for testing the activity of possible chemotherapeutic and inhibitory agents was established, and 4 such compounds were examined. Azaserine in low doses was extremely effective in inhibiting de novo purine biosynthesis. 6-Mereaptopurine also blocked de novo synthesis of the purines. A new possible antimetabolic compound; N-benzoylglycinamidine was tested. In low amounts, N-benzoylglycinamidine stimulated purine biosynthesis, but a large dose decreased both purine synthesis and respiration. The Novikoff tumour cell suspension was used to gain some knowledge of the mode of action of actinomycin D. This antibiotic inhibited cellular respiration, but not anaerobic glycolysis. Actinomycin D decreased nucleic acid biosynthesis and acid soluble guanine synthesis, but did not affect the formation of acid soluble adenine. Large amounts either of calcium pantothenate or of coenzyme A were able to reverse the inhibition of nucleic acid metabolism, and to reverse partially the inhibition of respiration. Coenzyme A was more effective than pantothenate. These findings appear to support the suggestion that actinomycin D interferes with coenzyme A-dependent reactions.

The Non-linear Dynamics of Meaning-Processing in Social Systems

description: Social order cannot be considered as a stable phenomenon because it contains an order of reproduced expectations. When the expectations operate upon one another, they generate a non-linear dynamics that processes meaning. Specific meaning can be stabilized, for example, in social institutions, but all meaning arises from a horizon of possible meanings. Using Luhmann's (1984) social systems theory and Rosen's (1985) theory of anticipatory systems, I submit equations for modeling the processing of meaning in inter-human communication. First, a self-referential system can use a model of itself for the anticipation. Under the condition of functional differentiation, the social system can be expected to entertain a set of models; each model can also contain a model of the other models. Two anticipatory mechanisms are then possible: one transversal between the models, and a longitudinal one providing the modeled systems with meaning from the perspective of hindsight. A system containing two anticipatory mechanisms can become hyper-incursive. Without making decisions, however, a hyper-incursive system would be overloaded with uncertainty.

description: Faces are highly deformable objects which may easily change their appearance over time. Not all face areas are subject to the same variability. Therefore decoupling the information from independent areas of the face is of paramount importance to improve the robustness of any face recognition technique. This paper presents a robust face recognition technique based on the extraction and matching of SIFT features related to independent face areas. Both a global and local (as recognition from parts) matching strategy is proposed. The local strategy is based on matching individual salient facial SIFT features as connected to facial landmarks such as the eyes and the mouth. As for the global matching strategy, all SIFT features are combined together to form a single feature. In order to reduce the identification errors, the Dempster-Shafer decision theory is applied to fuse the two matching techniques. The proposed algorithms are evaluated with the ORL and the IITK face databases. The experimental results demonstrate the effectiveness and potential of the proposed face recognition techniques also in the case of partially occluded faces or with missing information.

description: Ultracold dipolar Fermi gases represent relatively unexplored, strongly correlated systems arising from long-range and anisotropic interactions. We demonstrate the possibility of a spontaneous symmetry breaking biaxial phase in these systems, which may be realized in, e.g., gases of ultracold polar molecules or strongly magnetic atoms. This biaxial nematic phase is manifest in a spontaneous distortion of the Fermi surface perpendicular to the axis of polarization. We describe these dipolar interaction induced phases using Landau Fermi liquid theory.

description: (Abridged) We present numerical simulations of the spectral evolution and emission of radio components in relativistic jets. We have developed an algorithm (SPEV) for the transport of a population of non-thermal electrons including radiative losses. For large values of the ratio of gas pressure to magnetic field energy density, \ab \sim 6\times 10^4, quiescent jet models show substantial spectral evolution, with observational consequences only above radio frequencies. Larger values of the magnetic field (\ab \sim 6\times 10^2), such that synchrotron losses are moderately important at radio frequencies, present a larger ratio of shocked-to-unshocked regions brightness than the models without radiative losses, despite the fact that they correspond to the same underlying hydrodynamic structure. We also show that jets with a positive photon spectral index result if the lower limit γ_min of the non-thermal particle energy distribution is large enough. A temporary increase of the Lorentz factor at the jet inlet produces a traveling perturbation that appears in the synthetic maps as a superluminal component. We show that trailing components can be originated not only in pressure matched jets, but also in over-pressured ones, where the existence of recollimation shocks does not allow for a direct identification of such features as Kelvin-Helmholtz modes, and its observational imprint depends on the observing frequency. If the magnetic field is large (\ab \sim 6\times 10^2), the spectral index in the rarefaction trailing the traveling perturbation does not change much with respect to the same model without any hydrodynamic perturbation. If the synchrotron losses are considered the spectral index displays a smaller value than in the corresponding region of the quiescent jet model.

description: Electrons hopping on the sites of a three-dimensional pyrochlore lattice are shown to form topologically non-trivial insulating phases when the spin-orbit (SO) coupling and lattice distortions are present. Of 16 possible topological classes 9 are realized for various parameters in this model. Specifically, at half-filling undistorted pyrochlore lattice with SO term yields a 'pristine' strong topological insulator with Z2 index (1;000). At quarter filling various strong and weak topological phases are obtained provided that both SO coupling and uniaxial lattice distortion are present. Our analysis suggests that many of the non-magnetic insulating pyrochlores should be topological insulators.

description: The study of flavor changing neutrinos is a very active field of research. I will discuss the status of ongoing and near term experiments investigating neutrino properties at short distances from the source. In the next few years, the Double Chooz, RENO and Daya Bay reactor neutrino experiments will start looking for signatures of a non-zero value of the mixing angle $θ_{13}$ with much improved sensitivities. The MiniBooNE experiment is investigating the LSND anomaly by looking at both the $ν_μ \to ν_{e}$ and $\barν_μ \to \barν_{e}$ appearance channels. Recent results on cross section measurements will be discussed briefly.
