Overview

La psicóloga Marta Martínez Novoa nos invita a liberarnos del síndrome de la chica buena para priorizar nuestro bienestar emocional y establecer relaciones auténticas y equilibradas.Libérate del síndrome de la chica buena y reconecta contigo misma y con lo que realmente quieres tú. Si tienes la sensación de ser siempre la última de tu lista, si te cuesta tomar decisiones por lo que puedan pensar los demás, si te empeñas en cumplir siempre sus expectativas y la palabra «no» es inexistente en tu vocabulario, si te obligas a seguir en relaciones que no te aportan porque no quieres hacer daño? seguramente padeces el síndrome de la chica buena. En principio, ser buena no tiene nada de malo, pero puede convertirse en un problema cuando esa «bondad» se traduce en dificultades para poner límites, afrontar conflictos y defender tus valores; en definitiva, para ser quien tú quieres y no lo que quieren los demás. Pero ya está bien de vivir solo para dar, de no poder equivocarte, de tener que hacerte pequeña para que otros ocupen más espacio, de tener que apagar tu luz como si eso fuese a hacer que otros brillen más. La psicóloga Marta Martínez Novoa te guía en un viaje para analizar tu pasado y entender por qué te sientes así en el presente, para construir un futuro en el que seas tu máxima prioridad. En estas páginas hallarás las claves para liberarte de las falsas exigencias de bondad y aprender a cuidarte, sentirte segura y confiar en lo que haces.

Constraint Energy Minimizing Generalized Multiscale Finite Element Method for multi-continuum Richards equations

description: In fluid flow simulation, the multi-continuum model is a useful strategy. When the heterogeneity and contrast of coefficients are high, the system becomes multiscale, and some kinds of reduced-order methods are demanded. Combining these techniques with nonlinearity, we will consider in this paper a dual-continuum model which is generalized as a multi-continuum model for a coupled system of nonlinear Richards equations as unsaturated flows, in complex heterogeneous fractured porous media; and we will solve it by a novel multiscale approach utilizing the constraint energy minimizing generalized multiscale finite element method (CEM-GMsFEM). In particular, such a nonlinear system will be discretized in time and then linearized by Picard iteration (whose global convergence is proved theoretically). Subsequently, we tackle the resulting linearized equations by the CEM-GMsFEM and obtain proper offline multiscale basis functions to span the multiscale space (which contains the pressure solution). More specifically, we first introduce two new sources of samples, and the GMsFEM is used over each coarse block to build local auxiliary multiscale basis functions via solving local spectral problems, that are crucial for detecting high-contrast channels. Second, per oversampled coarse region, local multiscale basis functions are created through the CEM as constrainedly minimizing an energy functional. Various numerical tests for our approach reveal that the error converges with the coarse-grid size alone and that only a few oversampling layers, as well as basis functions, are needed.

Disruption of the actin cytoskeleton after microinjection of proteolytic fragments of alpha-actinin
Creators: name: Pavalko, Fredrick M.
name: Burridge, Keith
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: Alpha-actinin can be proteolytically cleaved into major fragments of 27 and 53 kD using the enzyme thermolysin. The 27-kD fragment contains an actin-binding site and we have recently shown that the 53-kD fragment binds to the cytoplasmic domain of beta 1 integrin in vitro (Otey, C. A., F. M. Pavalko, and K. Burridge. 1990. J. Cell Biol. 111:721-729). We have explored the behavior of the isolated 27- and 53-kD fragments of alpha-actinin after their microinjection into living cells. Consistent with its containing a binding site for actin, the 27-kD fragment was detected along stress fibers within 10-20 min after injection into rat embryo fibroblasts (REF-52). The 53-kD fragment of alpha-actinin, however, concentrated in focal adhesions of REF-52 cells 10-20 min after injection. The association of this fragment with focal adhesions in vivo is consistent with its interaction in vitro with the cytoplasmic domain of the beta 1 subunit of integrin, which was also localized at these sites. When cells were injected with greater than 5 microM final concentration of either alpha-actinin fragment and cultured for 30-60 min, most stress fibers were disassembled. At this time, however, many of the focal adhesions, particularly those around the cell periphery, remained after most stress fibers had gone. By 2 h after injection only a few small focal adhesions persisted, yet the cells remained spread. Identical results were obtained with other cell types including primary chick fibroblasts, BSC-1, MDCK, and gerbil fibroma cells. Stress fibers and focal adhesions reformed if cells were allowed to recover for 18 h after injection. These data suggest that introduction of the monomeric 27-kD fragment of alpha-actinin into cells may disrupt the actin cytoskeleton by interfering with the function of endogenous, intact alpha-actinin molecules along stress fibers. The 53-kD fragment may interfere with endogenous alpha-actinin function at focal adhesions or by displacing some other component that binds to the rod domain of alpha-actinin and that is needed to maintain stress fiber organization.

description: Domain wall skyrmions are skyrmions trapped inside a domain wall. We investigate domain wall skyrmions in chiral magnets using a fully analytic approach. Treating the Dzyaloshinskii-Moriya (DM) interaction perturbatively, we construct the low-energy effective theory of a magnetic domain wall in an $O(3)$ sigma model with the DM interaction and an easy-axis potential term, yielding a sine-Gordon model. We then construct domain wall skyrmions as sine-Gordon solitons along the domain wall. We also construct domain wall skyrmions on top of a pair of a domain wall and an anti-domain wall. One of characteristic feature of domain wall skyrmions is that both skyrmions and anti-skyrmions are equally stable inside the domain wall, unlike the bulk in which only one of them is stable.

A role of tyrosine phosphorylation in the formation of acetylcholine receptor clusters induced by electric fields in cultured Xenopus muscle cells

description: During the development of the neuromuscular junction, acetylcholine receptors (AChRs) become clustered in the postsynaptic membrane in response to innervation. In vitro, several non-neuronal stimuli can also induce the formation of AChR clusters. DC electric field (E field) is one of them. When cultured Xenopus muscle cells are exposed to an E field of 5-10 V/cm, AChRs become clustered along the cathode-facing edge of the cells within 2 h. Recent studies have suggested the involvement of tyrosine kinase activation in the action of several AChR clustering stimuli, including nerve, polymer beads, and agrin. We thus examined the role of tyrosine phosphorylation in E field-induced AChR clustering. An antibody against phosphotyrosine (PY) was used to examine the localization of PY-containing proteins in E field-treated muscle cells. We found that anti-PY staining was colocalized with AChR clusters along the cathodal edge of the cells. In fact, cathodal PY staining could be detected before the first appearance of AChR clusters. When cultures were subjected to E fields in the presence of a tyrosine kinase inhibitor, tyrphostin RG-50864, cathodal AChR clustering was abolished with a half maximal inhibitory dosage of 50 microM. An inactive form of tyrphostin (RG-50862) had no effect on the field-induced clustering. These data suggest that the activation of tyrosine kinases is an essential step in E field-induced AChR clustering. Thus, the actions of several disparate stimuli for AChR clustering seem to converge to a common signal transduction mechanism based on tyrosine phosphorylation at the molecular level.
New models and Big Bang Nucleosynthesis constraints in $f(Q)$ gravity

description: The $f(Q)$ theories of modified gravity arise from the consideration of non-metricity as the basic geometric quantity, and have been proven to be very efficient in describing the late-time Universe. We use the Big Bang Nucleosynthesis (BBN) formalism and observations in order to extract constraints on various classes of f(Q) models. In particular, we calculate the deviations that f(Q) terms bring on the freeze-out temperature in comparison to that of the standard $ΛCDM$ evolution, and then we impose the observational bound on $ |\frac{δ{T}_f}{{T}_f}|$ to extract constraints on the involved parameters of the considered models. Concerning the polynomial model, we show that the exponent parameter should be negative, while for the power-exponential model and the new hyperbolic tangent - power model we find that they pass the BBN constraints trivially. Finally, we examine two DGP-like $f(Q)$ models, and we extract the bounds on their model parameters. Since many gravitational modifications, although able to describe the late-time evolution of the Universe, produce too-much modification at early times and thus fall to pass the BBN confrontation, the fact that $f(Q)$ gravity can safely pass the BBN constraints is an important advantage of this modified gravity class.

Extracellular matrix contains insulin-like growth factor binding protein-5: potentiation of the effects of IGF-I

description: Insulin-like growth factor binding proteins (IGFBPs) have been shown to serve as carrier proteins for the insulin-like growth factors (IGFs) and to modulate their biologic effects. Since extracellular matrix (ECM) has been shown to be a reservoir for IGF-I and IGF-II, we examined the ECM of cultured human fetal fibroblasts and found that IGFBP-5 was incorporated intact into ECM, while mostly inert proteolytic fragments were found in the medium. In contrast, two other forms of IGFBP that are secreted by these cells were either present in ECM in minimal amounts (IGFBP-3) or not detected (IGFBP-4). Likewise, when purified IGFBPs were incubated with ECM, IGFBP-5 bound preferentially. IGFBP-5 was found to bind to types III and IV collagen, laminin, and fibronectin. Increasing salt concentrations inhibited the binding of IGFBP-5 to ECM and accelerated the release of IGFBP-5 from ECM, suggesting an ionic basis for this interaction. ECM-associated IGFBP-5 had a sevenfold decrease in affinity for IGF-I compared to IGFBP-5 in solution. Furthermore, when IGFBP-5 was present in cell culture substrata, it potentiated the growth stimulatory effects of IGF- I on fibroblasts. When IGFBP-5 was present only in the medium, it was degraded to a 22-kD fragment and had no effect on IGF-I-stimulated growth. We conclude that IGFBP-5 is present in fibroblast ECM, where it is protected from degradation and can potentiate the biologic actions of IGF-I. These findings provide a molecular explanation for the association of the IGF's with the extracellular matrix, and suggest that the binding of the IGF's to matrix, via IGFBP-5, may be important in mediating the cellular growth response to these growth factors.

description: The purpose of this study was to explore the functional role of the cytoplasmic domain of the alpha subunit of the alpha 5/beta 1 integrin, a fibronectin receptor. Mutant CHO cells that express very low levels of endogenous hamster alpha 5 subunit (CHO clone B2) were transfected with an expression vector containing full-length or truncated human alpha 5 cDNAs to form chimeric human alpha 5/hamster beta 1 integrins. Three transfectants were examined: B2a27 expresses a full-length human alpha 5 subunit with 27 amino acids in the cytoplasmic domain; B2a10 expresses an alpha 5 with a 17-amino acid cytoplasmic truncation; B2a1 expresses an alpha 5 with a 26-amino acid truncation. Levels of alpha 5/beta 1 surface expression in B2a27 and B2a10 cells were similar to that in wild type CHO cells. The expression of alpha 5/beta 1 in B2a1 cells was less, amounting to 15-20% of WT levels, despite message levels that were three to five times greater than those of B2a27. The transfectants were used to examine the role of the alpha 5 cytoplasmic domain in cell adhesion, cell motility, cytoskeletal organization, and integrin-mediated tyrosine phosphorylation. The adhesion characteristics of B2a27 and B2a10 cells on fibronectin substrata were similar to each other and to wild type CHO cells. B2a1 cells displayed slight reductions in the strength and rate of adhesion to fibronectin. Cell motility in the presence of fibronectin was similar for B2a27, B2a10, and wild type CHO cells, while the B2a1 cells were substantially less motile. Comparable degrees of cell spreading and extensive organization of actin filaments were observed for B2a27, B2a10, and wild type CHO cells on fibronectin substrata. The B2a1 cells spread to a lesser degree, and some organization of actin was observed; the untransfected B2 cells remained round on fibronectin substrata and showed no actin reorganization. Since the reduced motility and cell spreading observed in the B2a1 cells might be due either to reduced surface expression of alpha 5/beta 1 or to the truncation in the alpha 5 cytoplasmic domain, we used flow cytometric cell sorting to select populations of B2a1 and B2a27 cells expressing similar levels of cell surface alpha 5. The deficits in spreading and motility were present in B2a1 cells expressing high levels of alpha 5. Thus the region of the alpha 5 cytoplasmic domain adjacent to the membrane seems to play an important role in cytoskeletal organization and cell motility. We also examined whether alpha subunit truncation would affect integrin- mediated tyrosine phosphorylation.(ABSTRACT TRUNCATED AT 400 WORDS)

description: Under temperature oscillation, cyclic molecular machines such as catalysts and enzymes could harness energy from the oscillatory bath and use it to drive other processes. Using a novel geometrical approach, under fast temperature oscillation, we derive a general design principle for obtaining the optimal catalytic energy landscape that can harness energy from a temperature-oscillatory bath and use it to invert a spontaneous reaction. By driving the reaction against the spontaneous direction, the catalysts convert low free energy product molecules to high free energy reactant molecules. The design principle, derived for arbitrary cyclic catalysts, is expressed as a simple quadratic objective function that only depends on the reaction activation energies, and is independent of the temperature protocol. Since the reaction activation energies are directly accessible by experimental measurements, the objective function can be directly used to guide the search for optimal energy-harvesting catalysts.

description: Lithurgus andrewsi Cockerell
(Figs. 17–19)
 Lithurgus andrewsi Cockerell, 1909: 312. Holotype: NHML No. 17.a.2068a; ♀, near Flying-Fish Cove, Christmas Island, Australia.
 DIAGNOSIS: The female of this species can be distinguished easily from other Australian species of Lithurgus by the following combination of characters: distal terga with reddish setae as on sternal scopa (Fig. 17); mesoscutum rugulose; mesoscutellum mostly coarsely, densely foveate; facial prominence broadly convex, wide, about 0.6 times length of lower interorbital distance (Fig. 18); and vertex with contiguous punctures (Fig. 19).
 COMMENTS: This species is only known from Christmas Island, the type locality. As stated by Cockerell (1909), this species was described based on a female, the only female specimen among those studied by W.F. Kirby (1900) in his description of Megachile rotundipennis from Christmas Island (Appendix, vide infra). Thus, there is no need to designate it as lectotype.

description: Let $\mathsf M$ and $\mathsf M _{\mathsf S}$ respectively denote the Hardy-Littlewood maximal operator with respect to cubes and the strong maximal operator on $\mathbb{R}^n$, and let $w$ be a nonnegative locally integrable function on $\mathbb{R}^n$. We define the associated Tauberian functions $\mathsf{C}_{\mathsf{HL},w}(α)$ and $\mathsf{C}_{\mathsf{S},w}(α)$ on $(0,1)$ by \[ \mathsf{C}_{\mathsf{HL},w}(α) :=\sup_{\substack{E \subset \mathbb{R}^n \\ 0 < w(E) < \infty}} \frac{1}{w(E)}w(\{x \in \mathbb{R}^n : \mathsf M χ_E(x) > α\}) \] and \[ \mathsf{C}_{\mathsf{S},w}(α) := \sup_{\substack{E \subset \mathbb{R}^n \\ 0 < w(E) < \infty}} \frac{1}{w(E)}w(\{x \in \mathbb{R}^n : \mathsf M _{\mathsf S}χ_E(x) > α\}). \] Utilizing weighted Solyanik estimates for $\mathsf M$ and $\mathsf M_{\mathsf S}$, we show that the function $\mathsf{C}_{\mathsf{HL},w} $ lies in the local Hölder class $C^{(c_n[w]_{A_{\infty}})^{-1}}(0,1)$ and $\mathsf{C}_{\mathsf{S},w} $ lies in the local Hölder class $C^{(c_n[w]_{A_{\infty}^\ast})^{-1}}(0,1)$, where the constant $c_n>1$ depends only on the dimension $n$.

description: Nanovid (video-enhanced) microscopy was used to determine whether lateral diffusion in the plasma membrane of colloidal gold-tagged lipid molecules is confined or is unrestricted. Confinement could be produced by domains within the plane of the plasma membrane or by filamentous barriers within the pericellular matrix. Fluorescein- phosphatidylethanolamine (F1-PE), incorporated into the plasma membranes of cultured fibroblasts, epithelial cells and keratocytes, was labeled with 30-nm colloidal gold conjugated to anti-fluorescein (anti-F1). The trajectories of the gold-labeled lipids were used to compute diffusion coefficients (DG) and to test for restricted motion. On the cell lamella, the gold-labeled lipids diffused freely in the plasma membrane. Since the gold must move through the pericellular matrix as the attached lipid diffuses in the plasma membrane, this result suggests that any extensive filamentous barriers in the pericellular matrix are at least 40 nm from the plasma membrane surface. The average diffusion coefficients ranged from 1.1 to 1.7 x 10(-9) cm2/s. These values were lower than the average diffusion coefficients (DF) (5.4 to 9.5 x 10(-9) cm2/s) obtained by FRAP. The lower DG is partially due to the pericellular matrix as demonstrated by the result that heparinase treatment of keratocytes significantly increased DG to 2.8 x 10(-9) cm2/s, but did not affect DF. Pericellular matrix viscosity was estimated from the frictional coefficients computed from DG and DF and ranged from 0.5 to 0.9 poise for untreated cells. Heparinase treatment of keratocytes decreased the apparent viscosity to approximately 0.1 poise. To evaluate the presence of domains or barriers, the trajectories and corresponding mean square displacement (MSD) plots of gold-labeled lipids were compared to the trajectories and MSD plots resulting from computer simulations of random walks within corrals. Based on these comparisons, we conclude that, if there are domains limiting the diffusion of F1-PE, most are larger than 5 microns in diameter.

description: We study the synchronization of a superconducting qubit to an external optical field via a mechanical resonator in a hybrid optoelectromechanical system. The quantum trajectory method is employed to investigate synchronization. The bistability in one of the qubit polarization vectors, where the qubit rotates about the polarization vector, is observed for a single quantum trajectory run. The rotation in one of the stable states is synced with the external optical drive. When the number of trajectories is significantly increased, the qubit no longer displays bistability. However, synchronization with less quantum fluctuations is still observed. The scheme could be used to transfer the phase of the microwave qubit's rotation to a long-lived optical photon through synchronization, which may find applications in long-distance quantum communication. Also, this hybrid system can be used to study quantum synchronization.

Actomyosin-based Retrograde Flow of Microtubules in the Lamella of Migrating Epithelial Cells Influences Microtubule Dynamic Instability and Turnover and Is Associated with Microtubule Breakage and Treadmilling

description: We have discovered several novel features exhibited by microtubules (MTs) in migrating newt lung epithelial cells by time-lapse imaging of fluorescently labeled, microinjected tubulin. These cells exhibit leading edge ruffling and retrograde flow in the lamella and lamellipodia. The plus ends of lamella MTs persist in growth perpendicular to the leading edge until they reach the base of the lamellipodium, where they oscillate between short phases of growth and shortening. Occasionally “pioneering” MTs grow into the lamellipodium, where microtubule bending and reorientation parallel to the leading edge is associated with retrograde flow. MTs parallel to the leading edge exhibit significantly different dynamics from MTs perpendicular to the cell edge. Both parallel MTs and photoactivated fluorescent marks on perpendicular MTs move rearward at the 0.4 μm/min rate of retrograde flow in the lamella. MT rearward transport persists when MT dynamic instability is inhibited by 100-nM nocodazole but is blocked by inhibition of actomyosin by cytochalasin D or 2,3-butanedione–2-monoxime. Rearward flow appears to cause MT buckling and breaking in the lamella. 80% of free minus ends produced by breakage are stable; the others shorten and pause, leading to MT treadmilling. Free minus ends of unknown origin also depolymerize into the field of view at the lamella. Analysis of MT dynamics at the centrosome shows that these minus ends do not arise by centrosomal ejection and that ∼80% of the MTs in the lamella are not centrosome bound. We propose that actomyosin-based retrograde flow of MTs causes MT breakage, forming quasi-stable noncentrosomal MTs whose turnover is regulated primarily at their minus ends.
Resonant diffusion of normal alkanes in zeolites: Effect of the zeolite structure and alkane molecule vibrations

description: Diffusion of normal alkanes in one-dimensional zeolites is theoretically studied on the basis of the stochastic equation formalism. The calculated diffusion coefficient accounts for the vibrations of the diffusing molecule and zeolite framework, molecule-zeolite interaction, and specific structure of the zeolite. It is shown that when the interaction potential is predominantly determined by the zeolite pore structure, the diffusion coefficient varies periodically with the number of carbon atoms of the alkane molecule, a phenomenon called resonant diffusion. A criterion for observable resonance is obtained from the balance between the interaction potentials of the molecule due to the atomic and pore structures of the zeolite. It shows that the diffusion is not resonant in zeolites without pore structure, such as ZSM-12. Moreover, even in zeolites with developed pore structure no resonant dependence of the diffusion constant can be detected if the pore structure energy barriers are not at least three times higher than the atomic structure energy barriers. The role of the alkane molecule vibrations is examined as well and a surprising effect of suppression of the diffusion in comparison with the case of a rigid molecule is observed. This effect is explained with the balance between the static and dynamic interaction of the molecule and zeolite.

description: In the study of some dynamical systems the limsup set of a sequence of measurable sets is often of interest. The shrinking targets and recurrence are two of the most commonly studied problems that concern limsup sets. However, the zero-one laws for the shrinking targets and recurrence are usually treated separately and proved differently. In this paper, we introduce a generalized definition that can specialize into the shrinking targets and recurrence; our approach gives a unified proof of the zero-one laws for the two problems.

On the principal Ricci curvatures of a Riemannian 3-manifold

description: We study global obstructions to the eigenvalues of the Ricci tensor on a Riemannian 3-manifold. As a topological obstruction, we first show that if the 3-manifold is closed, then certain choices of the eigenvalues are prohibited: in particular, there is no Riemannian metric whose corresponding Ricci eigenvalues take the form $(-μ,f,f)$, where $μ$ is a positive constant and $f$ is a smooth positive function. We then concentrate on the case when one of the eigenvalues is zero. Here we show that if the manifold is complete and its Ricci eigenvalues take the form $(0,λ,λ)$, where $λ$ is a positive constant, then its universal cover must split isometrically. If the manifold is closed, scalar-flat, and its zero eigenspace contains a unit length vector field that is geodesic and divergence-free, then the manifold must be flat. Our techniques also apply to the study of Ricci solitons in dimension three.

Radiative turbulent mixing layers at high Mach numbers

description: Radiative turbulent mixing layers (TMLs) are ubiquitous in astrophysical environments, e.g., the circumgalactic medium (CGM), and are triggered by the shear velocity at interfaces between different gas phases. To understand the shear velocity dependence of TMLs, we perform a set of 3D hydrodynamic simulations with an emphasis on the TML properties at high Mach numbers $\mathcal{M}$. Since the shear velocity in mixing regions is limited by the local sound speed of mixed gas, high-Mach number TMLs develop into a two-zone structure: a Mach number-independent mixing zone traced by significant cooling and mixing, plus a turbulent zone with large velocity dispersions which expands with greater $\mathcal{M}$. Low-Mach number TMLs do not have distinguishable mixing and turbulent zones. The radiative cooling of TMLs at low and high Mach numbers is predominantly balanced by enthalpy consumption and turbulent dissipation respectively. Both the TML surface brightness and column densities of intermediate-temperature ions (e.g., O VI) scale as $\propto\mathcal{M}^{0.5}$ at $\mathcal{M} \lesssim 1$, but reach saturation ($\propto \mathcal{M}^0$) at $\mathcal{M} \gtrsim 1$. Inflow velocities and hot gas entrainment into TMLs are substantially suppressed at high Mach numbers, and strong turbulent dissipation drives the evaporation of cold gas. This is in contrast to low-Mach number TMLs where the inflow velocities and hot gas entrainment are enhanced with greater $\mathcal{M}$, and cold gas mass increases due to the condensation of entrained hot gas.
