Chillida en América. Un encuentro con la modernidad al otro lado del Atlántico
Cuadernos de Proyectos Arquitectónicos, 2023 En 1958 Eduardo Chillida recibe una beca de la Fundación Graham de Chicago en la que es alentado a profundizar en los aspectos de su trabajo más cercanos a la disciplina arquitectónica.

Polygonal excitations of spinning and levitating droplets [PDF]
Phys. Rev. Lett. 101, 234501 (2008), 2008 The shape of a weightless spinning liquid droplet is governed by the balance between the surface tension and centrifugal forces. The axisymmetric shape for slow rotation becomes unstable to a non-axisymmetric distortion above a critical angular velocity, beyond which the droplet progresses through a series of 2-lobed shapes.

Cardiovascular Adaptation to Weightlessness
SAE Technical Paper Series, 1982 Exposure to actual and simulated O g causes a significant central or cephalad shift of intravascular and interstitial fluid that triggers a complex set of cardiovascular and systemic adaptations. These adaptations are, in turn, directly responsible for the cardiovascular dysfunction that is apparent after return to normal gravity.

FoxO1 signaling in B cell malignancies and its therapeutic targeting
FEBS Letters, EarlyView.FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Process mining classification with a weightless neural network [PDF]
arXiv, 2020 Using a weightless neural network architecture WiSARD we propose a straightforward graph to retina codification to represent business process graph flows avoiding kernels, and we present how WiSARD outperforms the classification performance with small training sets in the process mining context.

Billiard dynamics of bouncing dumbbell [PDF]
, 2013 A system of two masses connected with a weightless rod (called dumbbell in this paper) interacting with a flat boundary is considered. The sharp bound on the number of collisions with the boundary is found using billiard techniques. In case, the ratio of masses is large and the dumbbell rotates fast, an adiabatic invariant is obtained.

arXiv, 2022 We show that the perverse t-structure induces a t-structure on the category $\mathcal{D}^A(S,\mathbb{Z}_\ell)$ of Artin $\ell$-adic complexes when $S$ is an excellent scheme of dimension less than $2$ and provide a counter-example in dimension $3$. The heart $\mathrm{Perv}^A(S,\mathbb{Z}_\ell)$ of this t-structure can be described explicitly in terms ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

On the shape of a lightweight drop on a horizontal plane [PDF]
Phys. Scr. 85 (2012) 045401, 2013 The shape of drop on a flat horizontal plane is obtained by including the first order of correction by the weight. The sphere solution of the weightless drop is used to introduce a new polar coordinate by which the perturbative expression for a region of a drop can be extended analytically to the entire surface of a drop having both the concave and the
