Cyanobacteria are unique among phytoplankton in their ability to controltheir depth in lakes by buoyancy regulation. They derive their buoyancyfrom gas vesicles, which if present in sufficient quantity will offsetthe excess buoyant density of other cell constituents. Cyanobacteria mayregulate buoyancy by one, or more, of three mechanisms: gas vesiclecollapse; regulation of gas vesicle formation; or changes in other components,especially carbohydrate. This chapter describes the techniquesdeveloped to elucidate the mechanisms of buoyancy regulation in laboratorycultures and to study the phenomena of vertical migration or stratificationby cyanobacteria in lakes.

description: Quels besoins peut-on déduire du vécu des enfants atteints de cancer et de celui de leurs parents ? Issu d’une expérience de stage, notre questionnement s’est précisé au fil de nos lectures. Plusieurs écrits récents publiés dans le domaine de l’oncologie pédiatrique relèvent la nécessité de donner la parole aux enfants. Ce travail est une revue de littérature composée de huit articles sélectionnés parmi les recherches actuelles qui concernent la perspective infantile. Le cancer de l’enfant exerçant un impact sur l’ensemble du système familial, il nous a paru nécessaire d’intégrer le vécu des parents à notre questionnement. Afin de pouvoir traiter correctement du sujet choisi, nous avons décidé de ne pas nous intéresser au vécu des frères et soeurs. Les résultats de recherche issus des différents articles sélectionnés se corroborent ou se complètent. Nous n’avons pas remarqué de divergences importantes. Au sein des discours des parents et enfants inclus dans les études de notre revue, nous avons pu identifier plusieurs besoins qui nous permettent de mieux saisir les enjeux tels qu’ils se posent pour eux. Dans les conditions particulières imposées par le cadre de la prise en soins, parents et enfant ressentent la nécessité de maintenir les liens familiaux qui les attachent. Des besoins en information, en participation à la réalisation des soins et aux prises de décisions ont notamment pu être relevés. La sensibilité des enfants à l’égard des relations qu’ils entretiennent avec les infirmières ressort également des résultats et témoignent d’enjeux identitaires sous-jacents. Finalement, en fonction de leur âge les enfants se positionnent différemment par rapport aux prises de décision, mais ils ressentent tous le besoin d’être entendus. Du côté des parents on peut noter un risque élevé encouru quant à leur état de santé général. Ils sont soumis à un stress important et à de vives tensions qui découlent de l’accumulation des tâches qui leur incombent. L’évaluation de leurs besoins et la prévention des risques encourus sur le long terme sont donc des interventions infirmières qu’il serait judicieux d’entreprendre si le cadre de la prise en soins le permet. Sur le plan de la recherche, une précision des critères permettant de favoriser l’intégration des enfants aux processus décisionnels semble souhaitable. Le développement d’outils permettant d’évaluer les réactions des enfants et leur perception de la situation font également partie des enjeux actuels.

description: We study a renormalizable model of Dirac fermion dark matter (DM) that communicates with the Standard Model (SM) through a pair of mediators -- one scalar, one fermion -- in the representation $(\boldsymbol{6},\boldsymbol{1}, \tfrac{4}{3})$ of the SM gauge group $\text{SU}(3)_{\text{c}} \times \text{SU}(2)_{\text{L}} \times \text{U}(1)_Y$. While such assignments preclude direct coupling of the dark matter to the Standard Model at tree level, we examine the many effective operators generated at one-loop order when the mediators are heavy, and find that they are often phenomenologically relevant. We reinterpret dijet and pair-produced resonance and $\text{jets} + E_{\text{T}}^{\text{miss}}$ searches at the Large Hadron Collider (LHC) in order to constrain the mediator sector, and we examine an array of DM constraints ranging from the observed relic density $Ω_χ h^2_{\text{Planck}}$ to indirect and direct searches for dark matter. Tree-level annihilation, available for DM masses starting at the TeV scale, is required in order to produce $Ω_χ h^2_{\text{Planck}}$ through freeze-out, but loops -- led by the dimension-five DM magnetic dipole moment -- are nonetheless able to produce signals large enough to be constrained, particularly by the XENON1T experiment. In some benchmarks, we find a fair amount of parameter space left open by experiment and compatible with freeze-out. In other scenarios, however, the open space is quite small, suggesting a need for further model-building and/or non-standard cosmologies.

Skew Class-balanced Re-weighting for Unbiased Scene Graph Generation

Year: 2023
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: An unbiased scene graph generation (SGG) algorithm referred to as Skew Class-balanced Re-weighting (SCR) is proposed for considering the unbiased predicate prediction caused by the long-tailed distribution. The prior works focus mainly on alleviating the deteriorating performances of the minority predicate predictions, showing drastic dropping recall scores, i.e., losing the majority predicate performances. It has not yet correctly analyzed the trade-off between majority and minority predicate performances in the limited SGG datasets. In this paper, to alleviate the issue, the Skew Class-balanced Re-weighting (SCR) loss function is considered for the unbiased SGG models. Leveraged by the skewness of biased predicate predictions, the SCR estimates the target predicate weight coefficient and then re-weights more to the biased predicates for better trading-off between the majority predicates and the minority ones. Extensive experiments conducted on the standard Visual Genome dataset and Open Image V4 \& V6 show the performances and generality of the SCR with the traditional SGG models.

description: Drought is a natural phenomenon that has widespread and significant effects on the global economy, environment, industries, and communities. early drought detection allows for the implementation, mitigation strategies and measures before its occurrence. Therefore, drought assessment is critical in the planning and management of water resource systems, particularly during dry climatic periods. However, assessing droughts is not always simple. This study described and evaluated drought conditions in Campania (southern Italy) using an in-situ measurement database that spans a centennial period from 1918 to 2019. With the assistance of these tools, water managers may more accurately assess droughts and prepare in advance for water management operations during droughts. Since water resource management in our area was crucial, the Campania region in southern Italy was selected as the case study region. To achieve the objectives of this study, an analysis of the precipitation coefficient of variation, assumed as index of inter-annual climate variability, was first performed over the period 1918-2015. Based on the findings of the above analysis and with the aim of reconstructing continuous long-term monthly scale precipitation time series, the in-situ point measurements (observed at the rain gauge locations) for the two datasets were projected on a 10×10 km resolution grid covering the whole region by using a geostatistical interpolation approach. Standardized Precipitation Index (SPI) and Standardized Precipitation Evapotranspiration Index (SPEI) time series were reconstructed for different accumulation timescales (from 3 to 48 months) to explore the full range of drought types. The modified Mann–Kendall and Sen's tests were applied to identify SPI and SPEI changes over time. In addition, the impact of the vegetation stress to better understand causes of the drought phenomenon was evaluated. Drought characteristics (Duration, severity and peak) were furthermore investigated for both moderate (SPI/SPEI ≤ −1) and extremely severe conditions (SPI/SPEI ≤ −2). Spatial autocorrelation was used too, to evaluate whether the different events studied have similar characteristics in terms of spatial aggregation, i.e., if there are areas increasingly affected by drought and how they are affected. The same events in which drought was already assessed with the SPI and SPEI indices were taken into consideration, i.e., the events of 1962, 1989, 2003 and 2017. [edited by Author]

description: Enzyme-enriched condensates can organize the spatial distribution of their substrates by catalyzing non-equilibrium reactions. Conversely, an inhomogeneous substrate distribution induces enzyme fluxes through substrate-enzyme interactions. We find that condensates move towards the center of a confining domain when this feedback is weak. Above a feedback threshold, they exhibit self-propulsion, leading to oscillatory dynamics. Moreover, catalysis-driven enzyme fluxes can lead to interrupted coarsening, resulting in equidistant condensate positioning, and to condensate division.

description: We use particle-based simulations to examine the static and driven collective phases of skyrmions interacting with random quenched disorder. We show that non-dissipative effects due to the Magnus term reduce the depinning threshold and strongly affect the skyrmion motion and the nature of the dynamic phases. The quenched disorder causes the Hall angle to become drive-dependent in the moving skyrmion phase, while different flow regimes produce distinct signatures in the transport curves. For weak disorder, the skyrmions form a pinned crystal and depin elastically, while for strong disorder the system forms a pinned amorphous state that depins plastically. At high drives the skyrmions can dynamically reorder into a moving crystal, with the onset of reordering determined by the strength of the Magnus term.

description: We study a system of $n$ Abelian vector fields coupled to $\frac 12 n(n+1)$ complex scalars parametrising the Hermitian symmetric space $\mathsf{Sp}(2n, {\mathbb R})/ \mathsf{U}(n)$. This model is Weyl invariant and possesses the maximal non-compact duality group $\mathsf{Sp}(2n, {\mathbb R})$. Although both symmetries are anomalous in the quantum theory, they should be respected by the logarithmic divergent term (the ``induced action'') of the effective action obtained by integrating out the vector fields. We compute this induced action and demonstrate its Weyl and $\mathsf{Sp}(2n, {\mathbb R})$ invariance. The resulting conformal higher-derivative $σ$-model on $\mathsf{Sp}(2n, {\mathbb R})/ \mathsf{U}(n)$ is generalised to the cases where the fields take their values in (i) an arbitrary Kähler space; and (ii) an arbitrary Riemannian manifold. In both cases, the $σ$-model Lagrangian generates a Weyl anomaly satisfying the Wess-Zumino consistency condition.

description: Hybrid devices based on the superconducting qubits have emerged as a promising platform for controlling the quantum states of macroscopic resonators. The nonlinearity added by a qubit can be a valuable resource for such control. Here we study a hybrid system consisting of a mechanical resonator longitudinally coupled to a transmon qubit. The qubit readout can be done by coupling to a readout mode like in c-QED setup. The coupling between the mechanical resonator and transmon qubit can be implemented by modulation of the SQUID inductance. In such a tri-partite system, we analyze the steady-state occupation of the mechanical mode when all three modes are dispersively coupled. We use the quantum-noise and the Lindblad formalism to show that the sideband cooling of the mechanical mode to its ground state is achievable. We further experimentally demonstrate that measurements of the thermomechanical motion is possible in the dispersive limit, while maintaining a large coupling between qubit and mechanical mode. Our theoretical calculations suggest that single-photon strong coupling is within the experimental reach in such hybrid devices.

Novel Sensors and Quantum Technology for Geodesy

Subjects: quantum technology, relativistic geodesy, Earth observation

description: Current developments in quantum physics and the application of general relativity open up enhanced prospects for satellite geodesy, gravimetric Earth observation and reference systems and thus support the GGOS goals in a unique way. These novel concepts include the application of atom interferometry for realizing quantum gravimetry/gradiometry, the enhanced use of laser interferometry for inter-satellite tracking and accelerometry at future gravity field missions, and relativistic geodesy with clocks for the determination of gravity potential differences via gravitational redshift measurements. We briefly illustrate those novel techniques and present in which fields geodesy and geosciences will benefit from them. We show various application areas ranging from the direct determination of physical heights and the monitoring of mass variations using clock networks up to the use of quantum technology for gravimetric Earth observation on ground and in space. Realizing these innovative methods is key to quantify climate change processes (groundwater changes, ice mass loss, seal level rise, etc.) with largely increased precision and resolution. The IAG project “Novel Sensors and Quantum Technology for Geodesy (QuGe)” advances those activities in close collaboration between geodesy and physics, see https://quge.iag-aig.org/

Classical tests of General Relativity in thick branes

Year: 2014
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Classical tests of General Relativity in braneworld scenarios have been investigated recently with the purpose of posing observational constraints on parameters of some models of infinitely thin brane. Here we consider the motion of test particles in a thick brane scenario that corresponds to a regularized version of the Garriga-Tanaka solution, which describes a black hole solution in RSII model, in the weak field regime. By adapting a mechanism previously formulated in order to describe the confinement of massive tests particles in a domain wall (that simulates classically the trapping of the Dirac field in a domain wall), we study the influence of the brane thickness on the four-dimensional (4D) path of massless particles. Although the geometry is not warped and, therefore, the bound motion in the transverse direction is not decoupled from the movement in the 4D-world, we can find an explicit solution for the light deflection and the time delay, if the motion in the fifth direction is a high frequency oscillation. We verify that, owing to the transverse motion, the light deflection and the time delay depend on the energy of the light rays. This feature may lead to the phenomenon of gravitational rainbow. We also consider the problem from a semi-classical perspective, investigating the effects of the brane thickness on the motion of the zero-mode in the 4D-world.

description: We attempt to interpret the cosmic-ray positron excess by injection from the nearby pulsar Geminga, assuming a two-zone diffusion scenario and an injection spectrum with a low energy cutoff. Since the high energy positrons and electrons from Geminga can induce $γ$ rays via inverse Compton scattering, we take into account the extended $γ$-ray observations around Geminga from HAWC for $\sim 10$ TeV and from Fermi-LAT for $\mathcal{O}(10)$ GeV. According to the extended $γ$-ray observation claimed by an analysis of Fermi-LAT data, we find that Geminga could explain the positron excess for a $30\%$ energy conversion efficiency into positrons and electrons. However, based on the constraint on the extended $γ$ rays given by another Fermi-LAT analysis, positrons from Geminga would be insufficient to account for the positron excess. A further robust analysis of Fermi-LAT data for the extended $γ$ rays would be crucial to determine whether Geminga can explain the positron excess or not.

description: We measure nonlocal third-order spatial correlations in non-degenerate ultracold gases of bosonic ($^{84}$Sr) and spin-polarized fermionic ($^{87}$Sr) strontium through studies of the formation rates for ultralong-range trimer Rydberg molecules. The trimer production rate is observed to be very sensitive to the effects of quantum statistics with a strong enhancement of up to a factor of six (3!) in the case of bosonic $^{84}$Sr due to bunching, and a marked reduction for spin-polarized fermionic $^{87}$Sr due to anti-bunching. The experimental results are compared to theoretical predictions and good agreement is observed. The present approach opens the way to {\it{in situ}} studies of higher-order nonlocal spatial correlations in a wide array of ultracold atomic-gas systems.

Spin-orbit torque for field-free switching in C_{3v} crystals

description: Spin-orbit torques in noncentrosymmetric polycrystalline magnetic heterostructures are usually described in terms of field-like and damping-like torques. However, materials with a lower symmetry point group can exhibit torques whose behavior substantially deviates from the conventional ones. In particular, based on symmetry arguments it was recently proposed that systems belonging to the C_{3v} point group display spin-orbit torques that can promote field-free switching [Liu et al. Nature Nanotechnology 16, 277 (2021)]. In the present work, we analyze the general form of the torques expected in C3v crystals using the Invariant Theory. We uncover several new components that arise from the coexistence of the three-fold rotation and mirror symmetries. Using both tight binding model and first principles simulations, we show that these unconventional torque components arise from the onset of trigonal warping of the Fermi surface and can be as large as the damping-like torque. In other words, the Fermi surface warping is a key indicator to the onset of field-free switching in low symmetry crystals.

description: Over the last decade there have been many advances in studies of quantum walks (QWs) including a momentum-space QW recently realized in our spinor Bose-Einstein condensate system. This QW possessed behaviors that generally agreed with theoretical predictions; however, it also showed momentum distributions that were not adequately explained by the theory. We present a theoretical model which proves that the coherent dynamics of the spinor condensate is sufficient to explain the experimental data without invoking the presence of a thermal cloud of atoms as in the original theory. Our numerical findings are supported by an analytical prediction for the momentum distributions in the limit of zero-temperature condensates. This current model provides more complete explanations to the momentum-space QWs that can be applied to study quantum search algorithms and topological phases in Floquet-driven systems.

description: The occurrences of collective quantum states, such as superconductivity (SC) and charge- or spin-densitywaves (CDWs or SDWs), are among the most fascinating phenomena in solids. To date much effort has been made to explore the interplay between different orders, yet little is known about the relationship of multiple orders of the same type. Here we report optical spectroscopy study on CDWs in the rare-earth tri-telluride compounds RTe3 (R = rare earth elements). Besides the prior reported two CDW orders, the study reveals unexpectedly the presence of a third CDW order in the series which evolves systematically with the size of R element. With increased chemical pressure, the first and third CDW orders are both substantially suppressed and compete with the second one by depleting the low energy spectral weight. A complete phase diagram for the multiple CDW orders in this series is established.

description: The legacy of NASA's K2 mission has provided hundreds of transiting exoplanets that can be revisited by new and future facilities for further characterization, with a particular focus on studying the atmospheres of these systems. However, the majority of K2-discovered exoplanets have typical uncertainties on future times of transit within the next decade of greater than four hours, making observations less practical for many upcoming facilities. Fortunately, NASA's Transiting exoplanet Survey Satellite (TESS) mission is reobserving most of the sky, providing the opportunity to update the ephemerides for $\sim$300 K2 systems. In the second paper of this series, we reanalyze 26 single-planet, K2-discovered systems that were observed in the TESS primary mission by globally fitting their K2 and TESS lightcurves (including extended mission data where available), along with any archival radial velocity measurements. As a result of the faintness of the K2 sample, 13 systems studied here do not have transits detectable by TESS. In those cases, we re-fit the K2 lightcurve and provide updated system parameters. For the 23 systems with $M_* \gtrsim 0.6 M_\odot$, we determine the host star parameters using a combination of Gaia parallaxes, Spectral Energy Distribution (SED) fits, and MESA Isochrones and Stellar Tracks (MIST) stellar evolution models. Given the expectation of future TESS extended missions, efforts like the K2 & TESS Synergy project will ensure the accessibility of transiting planets for future characterization while leading to a self-consistent catalog of stellar and planetary parameters for future population efforts.

description: The importance of classifying connections in large graphs has been the motivation for a rich line of work on distributed subgraph finding that has led to exciting recent breakthroughs. A crucial aspect that remained open was whether deterministic algorithms can be as efficient as their randomized counterparts, where the latter are known to be tight up to polylogarithmic factors. We give deterministic distributed algorithms for listing cliques of size $p$ in $n^{1 - 2/p + o(1)}$ rounds in the \congest model. For triangles, our $n^{1/3+o(1)}$ round complexity improves upon the previous state of the art of $n^{2/3+o(1)}$ rounds [Chang and Saranurak, FOCS 2020]. For cliques of size $p \geq 4$, ours are the first non-trivial deterministic distributed algorithms. Given known lower bounds, for all values $p \geq 3$ our algorithms are tight up to a $n^{o(1)}$ subpolynomial factor, which comes from the deterministic routing procedure we use.

description: Cette revue de littérature tente de mettre en évidence la manière dont la dimension spirituelle de l’expérience de santé se manifeste chez les enfants et les adolescents atteints de maladie chronique ainsi que chez leurs parents. Par cette problématique, nous explorons les intérêts pour la pratique infirmière ainsi que pour le système socio-sanitaire. Les résultats répondent à une partie de notre questionnement en mettant l’accent surtout sur l’aspect religieux de la spiritualité, ceci peut s’expliquer par la particularité des échantillons des articles (Afro-Américains). Il nous semble donc intéressant que les futures recherches soient menées en Europe, qu’elles incluent une différentiation plus marquée entre religion et spiritualité ainsi qu’une distinction entre l’enfant et l’adolescent en tenant compte des stades de développement.

description: Small-world networks---complex networks characterized by a combination of high clustering and short path lengths---are widely studied using the paradigmatic model of Watts and Strogatz (WS). Although the WS model is already quite minimal and intuitive, we describe an alternative formulation of the WS model in terms of a distance-dependent probability of connection that further simplifies, both practically and theoretically, the generation of directed and undirected WS-type small-world networks. In addition to highlighting an essential feature of the WS model that has previously been overlooked, this alternative formulation makes it possible to derive exact expressions for quantities such as the degree and motif distributions and global clustering coefficient for both directed and undirected networks in terms of model parameters.

description: Objective. Optical fibre dosimeters (OFDs) offer great promise for real-time in vivo dose measurement in radiation-based treatment modalities such as radiotherapy and brachytherapy. This is attributed to their many useful qualities such as high spatial resolution and sensitivity. However, there are several requirements that an optical fibre dosimeter must meet to be acceptable for dose measurement in a specified treatment modality. In this work, the dosimetric performance of a novel optical fibre dosimeter for use in external beam radiotherapy is presented. Approach. The dosimeter was characterised for photon beam energies between 6–15 MV using a Varian TrueBeam Linac at dose rates between 100–2400 MU/min and assessed based on its repeatability, dose dependence, dose rate dependence, energy dependence and dose-per-pulse dependence. Main Results. The results demonstrated excellent short-term repeatability of 0.3%, good linearity in response (R 2 > 0.9997), and minor dose rate dependence between 0.53%–2.49% for all beam qualities investigated. As the scintillator of the OFD is non-water equivalent, Monte-Carlo-TOPAS simulations were used to calculate the absorbed dose energy dependence. A dose-per-pulse dependence was also investigated and compared with dosimetry measurements made with an ionisation chamber and simulated from the treatment planning system. An over-response of 20% was found at the lowest investigated dose-per-pulse, and an under-response of 34% was found at the highest investigated dose-per-pulse. This is believed to be due to an intrinsic energy dependence making this type of OFD unsuitable for external beam radiotherapy dosimetry. Significance. The OFD evaluated in this work was primarily designed for high-dose-rate brachytherapy whereas this study includes the first measurements made in external beam radiotherapy and highlights the challenges of transferability of the dosimeter to a different radiation source.

Axial Current driven by Magnetization Dynamics in Weyl Semimetals

description: We theoretically study the axial current $\bm{j}_5$ (defined as the difference between the charge current with opposite chirality) in doped Weyl semimetal using a Green's function technique. We show that the axial current is controlled by the magnetization dynamics in a magnetic insulator attached to a Weyl semimetal. We find that the induced axial current can be detected by using ferromagnetic resonance or the inverse spin Hall effect and can be converted into charge current with no accompanying energy loss. These properties make Weyl semimetal advantageous for application to low-consumption electronics with new functionality.

Gas transport and storage in the Egeria densa Planch. lacunar system. Abstract

Egeria densa is a large aquatic angiosperm with an extensive lacunar airspace system in the shoots and roots. Oxygen produced in the chloroplasts is partitioned to both the external liquid and the lacunar system. In the light O2 entering and pressurising the lacunae diffuses to the roots down a 5% per metre concentration gradient. At the roots, some of the transported O2 sustains aerobic respiration of the tissue, and the excess is released into the sediment, oxidizing the rhizosphere. This longitudinal O2 transport is a diurnal phenomenon; corresponding diurnal fluctuations of 0.4 µgO2. cm-2. min-1 were found for the rhizosphere O2 flux.Diffusion of CO2 from roots to shoots provides an additional carbon source for photosynthesis. This results in a root-derived CO2 concentration gradient along the shoot axis.In the dark dissolved O2 around the plants may be depleted. A lower demand for external O2 by shoots with gas-filled lacunae, than by shoots with water-infiltrated lacunae, demonstrated that radial O2 diffusion in the lacunae assists nocturnal aeration of Egeria.

description: En Suisse, une femme sur cinq est victime de violence conjugale. Cette forme de violence a des conséquences sur la vie physique, psychologique, émotionnelle, environnementale et sociale de l’individu et de son entourage. De plus, elle engendre des coûts importants qui sont assumés par l’ensemble de la population. Le service d’urgences est un des lieux où les victimes se rendent en premier. L’infirmière est la personne de référence lors de l’accueil et de la prise en soins des patients. En lien avec ces différents constats, notre revue de littérature vise à répondre à la question de recherche suivante : « Comment l’infirmière peut-elle détecter des signes de violences chez des patientes admises dans un service d’urgences et proposer un accompagnement adéquat ? »

description: Ira Aldridge is widely recognized today for having been the first African American to earn an international reputation as a professional actor in the nineteenth century. During his first twenty-seven years performing throughout the British Isles, he was recognized as a skillful actor. He went on to perform Shakespeare with great success in major theatres on the Continent for the remaining fifteen years of his career. Yet his remarkable achievements abroad were seldom mentioned in newspapers in the United States during his lifetime. More stories about him finally began to circulate when it was announced in 1867 that he would be returning to America to perform in New York City, but he died in Poland shortly before he was due to sail. The many obituaries written about him immediately afterward earned him a measure of belated recognition.

description: Vav2, like all Dbl family proteins, possesses tandem Dbl homology (DH) and pleckstrin homology (PH) domains and functions as a guanine nucleotide exchange factor for Rho family GTPases. Whereas the PH domain is a critical positive regulator of DH domain function for a majority of Dbl family proteins, the PH domains of the related Vav and Vav3 proteins are dispensable for DH domain activity. Instead, Vav proteins contain a cysteine-rich domain (CRD) critical for DH domain function. We evaluated the contribution of the PH domain and the CRD to Vav2 guanine nucleotide exchange, signaling, and transforming activity. Unexpectedly, we found that mutations of the PH domain impaired Vav2 signaling, transforming activity, and membrane association. However, these mutations do not influence exchange activity on Rac and only slightly affect exchange on RhoA and Cdc42. We also found that the CRD was critical for the exchange activity in vitro and contributed to Vav2 membrane localization. Finally, we found that phosphoinositol 3-kinase activation synergistically enhanced Vav2 transforming and signaling activity by stimulating exchange activity but not membrane association. In conclusion, the PH domain and CRD are mechanistically distinct, positive modulators of Vav2 DH domain function in vivo.

description: Chimera is a fascinating phenomenon of coexisting synchronized and desynchronized behaviour that was discovered in networks of nonlocally coupled identical phase oscillators over ten years ago. Since then, chimeras were found in numerous theoretical and experimental studies and more recently in models of neuronal dynamics as well. In this work, we consider a generic model for a saddle-node bifurcation on a limit cycle representative for neural excitability type I. We obtain chimera states with multiple coherent regions (clustered chimeras/multi-chimeras) depending on the distance from the excitability threshold, the range of nonlocal coupling as well as the coupling strength. A detailed stability diagram for these chimera states as well as other interesting coexisting patterns like traveling waves are presented.
