description: Spiral and antispiral waves are studied numerically in two examples of oscillatory reaction-diffusion media and analytically in the corresponding complex Ginzburg-Landau equation (CGLE). We argue that both these structures are sources of waves in oscillatory media, which are distinguished only by the sign of the phase velocity of the emitted waves. Using known analytical results in the CGLE, we obtain a criterion for the CGLE coefficients that predicts whether antispirals or spirals will occur in the corresponding reaction-diffusion systems. We apply this criterion to the FitzHugh-Nagumo and Brusselator models by deriving the CGLE near the Hopf bifurcations of the respective equations. Numerical simulations of the full reaction-diffusion equations confirm the validity of our simple criterion near the onset of oscillations. They also reveal that antispirals often occur near the onset and turn into spirals further away from it. The transition from antispirals to spirals is characterized by a divergence in the wavelength. A tentative interpretaion of recent experimental observations of antispiral waves in the Belousov-Zhabotinsky reaction in a microemulsion is given.

description: Traditional Knowledge (TK) systems have always been integral to the survival and adaptation of human societies. Yet, they enjoy a fairly recent recognition and popularization by scientists, the media, politicians, corporates and the wider public. In this paper we present a typology of key driving forces behind the popularization of TK held by marginal communities: an equality preference motive, a value motive, a compliance motive, a scarcity motive and a strategic motive. Secondly, through the use of a simple model, we discuss the hype’s impact on marginal communities. Moreover, we critically assess the outcome of a number of policy instruments that intend, in part, to protect traditional knowledge bases of such communities. Our analysis primarily draws upon secondary literature; policy documents and case studies within economics, the social sciences, conservation biology and legal studies. We argue that whilst the public and institutional hype around TK may have resulted in its prioritization within international conventions and frameworks, its institutionalization may have adversely impacted marginalized communities, and in particular contexts, unintentionally led to the creation of “new” marginals. We purport that the traditional innovation incentive motive does not hold for protecting TK within a private property regime. Instead we identify a conservation incentive motive and a distribution motive that justify deriving policy instruments that focus on TK to protect marginal communities.

description: Previous studies have identified regulatory preemption and differentiation as two main motives for participation in voluntary environmental programs (VEPs). This research examines the motivations of livestock farmers to participate in the Michigan Agricultural Environmental Assurance Program (MAEAP). It employs a signaling model of interaction between the regulator and livestock farmers under imperfect information to analyze the potential equilibria of participation decisions in VEPs. Data from a survey of livestock farmers in Michigan is analyzed to test hypotheses regarding the realized equilibrium in MAEAP participation. The results suggest that livestock farmers who are interested in regulatory preemption are more likely to be MAEAP-verified while those who are interested in differentiation are less likely to be verified at the time of the survey. Consistent with the model predictions under the regulatory preemption equilibrium, MAEAP-certified farms also perceived more stringent enforcement effort by the regulators.

description: Selective removal of heavy metals from water is a complex topic. We present a theoretical computational approach, supported by experimental evidences, to design a functionalized nanomaterial that is able to selectively capture metallic ions from water in a self-assembling process. A theoretical model is used to map an experimental mixture of Ag nanoparticles and either Co$^{2+}$ or Ni$^{2+}$ onto an additive highly asymmetric attractive Lennard Jones binary mixture. Extensive NVT (constant number of particles, volume, and temperature) Monte Carlo simulations are performed to derive a set of parameters that first induce aggregation among the two species in solution and then affect the morphology of the aggregates. The computational predictions are thus compared with the experimental results. The gathered insights can be used as guidelines for the prediction of an optimal design of a new generation of selective nanoparticles to be used for metallic ion adsorption and hence for maximizing the trapping of ions in an aqueous solution.

description: 1. The six MERLIN Sectoral Strategies provide a vision for integrating Nature-based Solutions (NbS) into key economic sectors (Agriculture; Hydropower; Insurance; Navigation; Peat Extraction; Water Supply and Sanitation).

2. Economic sectors both depend on and impact freshwater ecosystems—NbS align private benefits with public goods like flood risk mitigation.

3. The business case for NbS includes cost reduction, risk management, regulatory compliance, sustainability commitments, and brand value.

4. The Strategies promote not only freshwater measures but also a shift toward recognizing natural capital as a business priority.

5. These Strategies aim to foster Communities of Practice (CoPs), engaging businesses, policymakers, financial institutions, and sectoral associations. as well as other civic and financial institutions.

6. Actions cover 'why,' 'what,' 'when,' and 'who'— starting with evidence gathering, followed by knowledge sharing, capacity building, policy shaping, and securing funding.

7. Collaboration is key, requiring cross-sector partnerships at catchment, national, and EU levels, alongside policy support from nonenvironmental sectors.

8. An enabling policy environment is essential, with non-environmental sectors (e.g., Agriculture, Energy) needing to support NbS.

9. With rising economic competitiveness concerns, sectors show interest in NbS, but further work is needed to turn strategies into action.

description: Effects of the U_A(1) breaking interaction on the low-lying nonet scalar mesons are studied using the extended Nambu-Jona-Lasinio model. The strength of the U_A(1) breaking interaction is determined by the electromagnetic decays of the eta meson. We find that the U_A(1) breaking interaction gives rise to about 150 MeV mass difference between the sigma and a_0 mesons. We also find that the strangeness content in the σmeson is about 15%. The calculated mass of the I=1/2 state is about 200 MeV heavier than that of the I=1 state. The order of these masses is not likely to change within this model.

Accurate 6D Object Pose Estimation by Pose Conditioned Mesh Reconstruction

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Current 6D object pose methods consist of deep CNN models fully optimized for a single object but with its architecture standardized among objects with different shapes. In contrast to previous works, we explicitly exploit each object's distinct topological information i.e. 3D dense meshes in the pose estimation model, with an automated process and prior to any post-processing refinement stage. In order to achieve this, we propose a learning framework in which a Graph Convolutional Neural Network reconstructs a pose conditioned 3D mesh of the object. A robust estimation of the allocentric orientation is recovered by computing, in a differentiable manner, the Procrustes' alignment between the canonical and reconstructed dense 3D meshes. 6D egocentric pose is then lifted using additional mask and 2D centroid projection estimations. Our method is capable of self validating its pose estimation by measuring the quality of the reconstructed mesh, which is invaluable in real life applications. In our experiments on the LINEMOD, OCCLUSION and YCB-Video benchmarks, the proposed method outperforms state-of-the-arts.

description: Abstract: Electroluminescence of colloidal nanocrystals promises a new generation of high-performance and solution-processable light-emitting diodes. The operation of nanocrystal-based light-emitting diodes relies on the radiative recombination of electrically generated excitons. However, a fundamental question—how excitons are electrically generated in individual nanocrystals—remains unanswered. Here, we reveal a nanoscopic mechanism of sequential electron-hole injection for exciton generation in nanocrystal-based electroluminescent devices. To decipher the corresponding elementary processes, we develop electrically-pumped single-nanocrystal spectroscopy. While hole injection into neutral quantum dots is generally considered to be inefficient, we find that the intermediate negatively charged state of quantum dots triggers confinement-enhanced Coulomb interactions, which simultaneously accelerate hole injection and hinder excessive electron injection. In-situ/operando spectroscopy on state-of-the-art quantum-dot light-emitting diodes demonstrates that exciton generation at the ensemble level is consistent with the charge-confinement-enhanced sequential electron-hole injection mechanism probed at the single-nanocrystal level. Our findings provide a universal mechanism for enhancing charge balance in nanocrystal-based electroluminescent devices.

description: Abstract: Volcanic eruptions are thought to be a key driver of rapid climate perturbations over geological time, such as global cooling, global warming, and changes in ocean chemistry. However, identification of stratospheric volcanic eruptions in the geological record and their causal link to the mass extinction events during the past 540 million years remains challenging. Here we report unexpected, large mass-independent sulphur isotopic compositions of pyrite with Δ33S of up to 0.91‰ in Late Ordovician sedimentary rocks from South China. The magnitude of the Δ33S is similar to that discovered in ice core sulphate originating from stratospheric volcanism. The coincidence between the large Δ33S and the first pulse of the Late Ordovician mass extinction about 445 million years ago suggests that stratospheric volcanic eruptions may have contributed to synergetic environmental deteriorations such as prolonged climatic perturbations and oceanic anoxia, related to the mass extinction.

description: We have made a multiwavelength study of the overlapping error boxes of the unidentified gamma-ray sources TeV J2032+4130 and 3EG J2033+4118 in the direction of the Cygnus OB2 association (d = 1.7 kpc) in order to search for a point-source counterpart of the first unidentified TeV source. Optical identifications and spectroscopic classifications for the brighter X-ray sources in ROSAT PSPC and Chandra ACIS images are obtained, without finding a compelling counterpart. The classified X-ray sources are a mix of early and late-type stars, with one exception. The brightest source in the Chandra observation is a new, hard absorbed source that is both transient and rapidly variable. It lies 7' from the centroid of the TeV emission, which places it outside of the claimed 2 sigma location (r = 4.8'). A possible eclipse or "dip" transition is seen in its light curve. With a peak 1-10 keV luminosity of 7 x 10^(32) (d/1.7 kpc})^2 ergs s^(-1), this source could be a quiescent low-mass X-ray binary that lies beyond the Cyg OB2 association. A coincident, reddened optical object of R = 20.4, J = 15.4, H = 14.2, and K = 13.4 is observed, but not yet classified due to the lack of obvious emission or absorption features in its spectrum. Alternatively, this Chandra} and optical source might be a considered a candidate for a proton blazar, a long hypothesized type of radio-weak gamma-ray source. More detailed observations will be needed to determine the nature of this variable X-ray source, and to assess the possibility of its connection with TeV J2032+4130.

description: In a ferromagnet, an applied electric field $\bf E$ invariably produces an anomalous Hall current ${\bf J}_H$ that flows perpendicular to the plane defined by $\bf E$ and $\bf M$ (the magnetization). For decades, the question whether ${\bf J}_H$ is dissipationless (independent of the scattering rate), has been keenly debated without experimental resolution. In the ferromagnetic spinel CuCr$_2$Se$_{4-x}$Br$_x$, the resistivity $ρ$ (at low temperature) may be increased 1000 fold by varying $x$(Br), without degrading the $\bf M$. We show that ${\bf J}_H/E$ (normalized per carrier, at 5 K) remains unchanged throughout. In addition to resolving the controversy experimentally, our finding has strong bearing on the generation and study of spin-Hall currents in bulk samples.

The first game is described by the quantum formalism of spin one half system for which two noncommuting observables are measured. The second game corresponds to the spin one case. Quantum logical orthocomplemented nondistributive lattices for these two games are presented. Interference terms for the probability amplitudes are analyzed by using so called contextual approach to probability (in the von Mises frequency approach). We underline that our games are not based on using of some microscopic systems. The whole scenario is macroscopic.

description: Diese Dissertation ist eine kumulative Arbeit im Bereich der Mensch-Computer-Interaktion und untersucht sowie evaluiert haptische Steuerungen und deren Anwendungen. Sie besteht aus drei wissenschaftlichen Arbeiten: Die erste Arbeit, ”Haptic and Auditive Mesh Inspection for Blind 3D Modelers” (ASSETS 2020), beschreibt die Implementierung einer neuartigen haptischen Schnittstelle für blinde 3D-Modellierer. Das beschriebene System ist das Ergebnis einer engen Zusammenarbeit mit der Blindenschule Marburg (BLISTA) und ermöglicht es blinden Nutzern, virtuelle 3D-Meshes auditiv und taktil zu inspizieren. Dieses haptisch-auditive Mesh-Inspektionssystem wurde in einer Studie mit 20 blinden Teilnehmenden evaluiert und mit dem Stand der Technik verglichen. Die Ergebnisse zeigen, dass unser neuartiges System die Fehlerquote senkt, die Geschwindigkeit erhöht und die Nutzerzufriedenheit verbessert. Aufbauend auf der Idee des haptischen Modellierens stellt die zweite Arbeit, ”Digitizing Interlocking Building Blocks” (VMV 2023), eine neue haptische Schnittstelle in Form digitalisierbarer Klemmbausteine vor und verfolgt damit das Ziel einer intuitiven, taktilen Mensch-Computer-Interaktion. Dieser Teil konzentriert sich auf die Hardware- und Softwareentwicklung eines solchen Systems und diskutiert dessen Implementierung, Komponenten und mögliche Anwendungen. In der dritten Arbeit, ”Using Interlocking Building Blocks as a Game Interface” (GAMES: Research and Practice 2025), wird das zuvor entwickelte System der Klemmbausteine weiter verbessert. Eine umfassende Nutzerstudie wird im Kontext eines Puzzlespiels durchgeführt, das mit unserer Schnittstelle gesteuert wird. Die Ergebnisse dieser Studie zeigen eine signifikante Verbesserung der Nutzerleistung sowie gesteigerte Nutzererfahrungsmetriken im Vergleich zu einer herkömmlichen Computermaus. Zudem werden die Vorteile der Schnittstelle analysiert und mögliche zukünftige Entwicklungen diskutiert. Die Ergebnisse dieser Dissertation zeigen, dass der Einsatz haptischer Schnittstellen und speziell für Haptik entwickelte Software die
Mensch-Computer-Interaktion erheblich verbessern kann. In unseren Anwendungen steigern haptische Schnittstellen die Effizienz, Genauigkeit, das Engagement sowie die allgemeine Nutzererfahrung im Vergleich zum Stand der Technik.

description: The problem of obtaining necessary and sufficient conditions for local existence of non-negative solutions in Lebesgue spaces for semilinear heat equations having monotonically increasing source term $f$ has only recently been resolved (Laister et al. (2016)). There, for the more difficult case of initial data in $L^1$, a necessary and sufficient integral condition on $f$ emerged. Here, subject to this integral condition, we consider other fundamental properties of solutions with $L^1$ initial data of indefinite sign, namely: uniqueness, regularity, continuous dependence and comparison. We also establish sufficient conditions for the global-in-time continuation of solutions for small initial data in $L^1$.

description: I survey physics theories involving parallel universes, which form a natural four-level hierarchy of multiverses allowing progressively greater diversity. Level I: A generic prediction of inflation is an infinite ergodic universe, which contains Hubble volumes realizing all initial conditions - including an identical copy of you about 10^{10^29} meters away. Level II: In chaotic inflation, other thermalized regions may have different effective physical constants, dimensionality and particle content. Level III: In unitary quantum mechanics, other branches of the wavefunction add nothing qualitatively new, which is ironic given that this level has historically been the most controversial. Level IV: Other mathematical structures give different fundamental equations of physics. The key question is not whether parallel universes exist (Level I is the uncontroversial cosmological concordance model), but how many levels there are. I discuss how multiverse models can be falsified and argue that there is a severe "measure problem" that must be solved to make testable predictions at levels II-IV.

description: This paper examines whether human capital levels diverged across Chinese cities between 1990 and 2010. By employing a series of instruments for the initial human capital share, consistent positive feedback between current human capital levels on the subsequent growth of human capital in the 2000s is found. The findings are also robust to alternative instrumental variables. Further evidence suggests that a city's industry structure does not explain the positive feedbacks, but rather urban amenities appear to be the primary causal factor. To mitigate large provincial inequality in development, China should mitigate growing differentials in human capital by improving local urban amenities.

description: The first measurement of longitudinal decorrelations of harmonic flow amplitudes $v_n$ for $n=2$, 3 and 4 in Xe+Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44$ TeV is obtained using 3 $μ\textrm{b}^{-1}$ of data with the ATLAS detector at the LHC. The decorrelation signal for $v_3$ and $v_4$ is found to be nearly independent of collision centrality and transverse momentum ($p_{\mathrm{T}}$) requirements on final-state particles, but for $v_2$ a strong centrality and $p_{\mathrm{T}}$ dependence is seen. When compared with the results from Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV, the longitudinal decorrelation signal in mid-central Xe+Xe collisions is found to be larger for $v_2$, but smaller for $v_3$. Current hydrodynamic models reproduce the ratios of the $v_n$ measured in Xe+Xe collisions to those in Pb+Pb collisions but fail to describe the magnitudes and trends of the ratios of longitudinal flow decorrelations between Xe+Xe and Pb+Pb. The results on the system-size dependence provide new insights and an important lever-arm to separate effects of the longitudinal structure of the initial state from other early-time and late-time effects in heavy-ion collisions.

description: The micromechanism-based stepwise strain hardening behaviour of copper single crystals significantly depends on the competition and collaboration between dislocation slip and deformation twinning. A crystal plasticity-based model of the strain hardening characteristics associated with slip and twinning interactions is proposed that focuses on modelling the stepwise strain hardening behaviour. An accumulated twin volume fraction is incorporated into the evolution of slip resistance to model slip–twinning (S-T) interactions at small strains. Then, the following stress fluctuation stage caused by the crystal reorientation is related to the twinning–twinning (T-T) interactions. Upon deformation to a large strain, a saturated hardening law including the slip–slip (S-S) interactions in the twinned region and the accumulated slip are presented. The effects of the initial crystal orientation and twinning on distinguished hardening stages are investigated. The stepwise strain hardening model reveals the dominating hardening mechanism at the initial hardening stage, which has been identified for orientation-dependent copper single crystals by investigating the slip and twinning increments. The stress fluctuation of a copper single crystal with a particular grain orientation can be described by introducing the evolution of the twin volume fraction and its saturation value, which allows an in-depth understanding of the evolution of large plastic deformation.

description: Additional file 4: Table S2. Transcriptome analysis was performed on MCF-7 and MDA-MB-231 cells treated with 6.0 μM and 12.0 μM CTet for 24 hours. The genes down-regulated in both MCF-7 and MDA-MB-231 cell lines, either in 6.0 μM and 12.0 μM CTet treatment conditions, were selected using GeneSifter software. The software analysis allowed to identify a list of 177 genes significantly (p < 0.01) down-regulated in both cell lines. (PDF 92 KB)
Revealing stellar brightness profiles by means of microlensing fold caustics

description: With a handful of measurements of limb-darkening coefficients, galactic microlensing has already proven to be a powerful technique for studying atmospheres of distant stars. Survey campaigns such as OGLE-III are capable of providing ~ 10 suitable target stars per year that undergo microlensing events involving passages over the caustic created by a binary lens which last from a few hours to a few days and allow to resolve the stellar atmosphere by frequent broadband photometry. For a caustic exit lasting 12 h and a photometric precision of 1.5%, a moderate sampling interval of 30 min (corresponding to ~ 25-30 data points) is sufficient for providing a reliable measurement of the linear limb-darkening coefficient Gamma with an uncertainty of ~ 8% which reduces to ~ 3% for a reduced sampling interval of 6 min for the surroundings of the end of the caustic exit. While some additional points over the remaining parts of the lightcurve are highly valuable, a denser sampling in these regions provides little improvements. Unless a high-precision measurement is desired, limb-darkening coefficients for several filters can be obtained or observing time can be spent on other targets during the same night. The adoption of an inappropriate stellar intensity profile yields characteristic systematics in the model residuals which can be distinguished from those arising from effects causing an acceleration between source and caustic which are however unlikely to affect the lightcurve significantly for most events, although a free acceleration parameter blurs the limb-darkening measurement if the passage duration cannot be accurately determined.

description: NASA has developed a "Figure of Merit" method to grade the fidelity of lunar simulants for scientific and engineering purposes. Here we extend the method to grade asteroid simulants, both regolith and cobble variety, and we apply the method to the newly developed asteroid regolith and cobble simulant UCF/DSI-CI-2. The reference material that is used to evaluate this simulant for most asteroid properties is the Orgueil meteorite. Those properties are the mineralogical and elemental composition, grain density, bulk density of cobbles, magnetic susceptibility, mechanical strength of cobbles, and volatile release patterns. To evaluate the regolith simulant's particle sizing we use a reference model that was based upon the sample returned from Itokawa by Hayabusa, the boulder count on Hayabusa, and four cases of disrupted asteroids that indicate particle sizing of the subsurface material. Compared to these references, the simulant has high figures of merit, indicating it is a good choice for a wide range of scientific and engineering applications. We recommend this methodology to the wider asteroid community and in the near future will apply it to additional asteroid simulants currently under development.

Solving connectivity problems parameterized by treedepth in single-exponential time and polynomial space

description: A breakthrough result of Cygan et al. (FOCS 2011) showed that connectivity problems parameterized by treewidth can be solved much faster than the previously best known time $\mathcal{O}^*(2^{\mathcal{O}(tw \log(tw))})$. Using their inspired Cut\&Count technique, they obtained $\mathcal{O}^*(α^{tw})$ time algorithms for many such problems. Moreover, they proved these running times to be optimal assuming the Strong Exponential-Time Hypothesis. Unfortunately, like other dynamic programming algorithms on tree decompositions, these algorithms also require exponential space, and this is widely believed to be unavoidable. In contrast, for the slightly larger parameter called treedepth, there are already several examples of algorithms matching the time bounds obtained for treewidth, but using only polynomial space. Nevertheless, this has remained open for connectivity problems. In the present work, we close this knowledge gap by applying the Cut\&Count technique to graphs of small treedepth. While the general idea is unchanged, we have to design novel procedures for counting consistently cut solution candidates using only polynomial space. Concretely, we obtain time $\mathcal{O}^*(3^d)$ and polynomial space for Connected Vertex Cover, Feedback Vertex Set, and Steiner Tree on graphs of treedepth $d$. Similarly, we obtain time $\mathcal{O}^*(4^d)$ and polynomial space for Connected Dominating Set and Connected Odd Cycle Transversal.

description: Linear and nonlinear dynamic properties of a reentrant ferromagnet Cu$_{0.2}$Co$_{0.8}$Cl$_{2}$-FeCl$_{3}$ graphite bi-intercalation compound are studied using AC and DC magnetic susceptibility. This compound undergoes successive phase transitions at the transition temperatures $T_{h}$ (= 16 K), $T_{c}$ (= 9.7 K), and $T_{RSG}$ (= 3.5 K). The static and dynamic behaviors of the reentrant spin glass phase below $T_{RSG}$ are characterized by those of normal spin glass phase with critical exponent $β$ = 0.57 $\pm$ 0.10, a dynamic critical exponent $x$ = 8.5 $\pm$ 1.8, and an exponent $p$ (= 1.55 $\pm$ 0.13) for the de Almeida -Thouless line. A prominent nonlinear susceptibility is observed between $T_{RSG}$ and $T_{c}$ and around $T_{h}$, suggesting a chaotic nature of the ferromagnetic phase ($T_{RSG} \leq T \leq T_{c}$) and the helical spin ordered phase ($T_{c} \leq T \leq T_{h}$). The aging phenomena are observed both in the RSG and FM phases, with the same qualitative features as in normal spin glasses. The aging of zero-field cooled magnetization indicates a drastic change of relaxation mechanism below and above $T_{RSG}$. The time dependence of the absorption $χ^{\prime \prime}$ is described by a power law form ($\approx t^{-b^{\prime \prime}}$) in the ferromagnetic phase, where $b^{\prime \prime} \approx 0.074 \pm 0.016$ at $f$ = 0.05 Hz and $T$ = 7 K. No $ωt$-scaling law for $χ^{\prime \prime}$ [$\approx (ωt)^{-b^{\prime \prime}}$] is observed.

description: The Fokker-Planck equation provides complete statistical description of a particle undergoing random motion in a solvent. In the presence of Lorentz force due to an external magnetic field, the Fokker-Planck equation picks up a tensorial coefficient, which reflects the anisotropy of the particle's motion. This tensor, however, can not be interpreted as a diffusion tensor; there are antisymmetric terms which give rise to fluxes perpendicular to the density gradients. Here, we show that for an inhomogeneous magnetic field these nondiffusive fluxes have finite divergence and therefore affect the density evolution of the system. Only in the special cases of a uniform magnetic field or carefully chosen initial condition with the same symmetry as the magnetic field can these fluxes be ignored in the density evolution.
