text: Mechanical systems facilitate the development of a hybrid quantum technology
comprising electrical, optical, atomic and acoustic degrees of freedom1, and entanglement
is essential to realize quantum-enabled devices. Continuous-variable entangled
fields—known as Einstein–Podolsky–Rosen (EPR) states—are spatially separated two-mode
squeezed states that can be used for quantum teleportation and quantum communication2.
In the optical domain, EPR states are typically generated using nondegenerate
optical amplifiers3, and at microwave frequencies Josephson circuits can serve
as a nonlinear medium4,5,6. An outstanding goal is to deterministically generate
and distribute entangled states with a mechanical oscillator, which requires a
carefully arranged balance between excitation, cooling and dissipation in an ultralow
noise environment. Here we observe stationary emission of path-entangled microwave
radiation from a parametrically driven 30-micrometre-long silicon nanostring oscillator,
squeezing the joint field operators of two thermal modes by 3.40 decibels below
the vacuum level. The motion of this micromechanical system correlates up to 50
photons per second per hertz, giving rise to a quantum discord that is robust
with respect to microwave noise7. Such generalized quantum correlations of separable
states are important for quantum-enhanced detection8 and provide direct evidence
of the non-classical nature of the mechanical oscillator without directly measuring
its state9. This noninvasive measurement scheme allows to infer information about
otherwise inaccessible objects, with potential implications for sensing, open-system
dynamics and fundamental tests of quantum gravity. In the future, similar on-chip
devices could be used to entangle subsystems on very different energy scales,
such as microwave and optical photons.

text: It is well known that many problems in image recovery, signal processing,
and machine learning can be modeled as finding zeros of the sum of maximal monotone
and Lipschitz continuous monotone operators. Many papers have studied forward-backward
splitting methods for finding zeros of the sum of two monotone operators in Hilbert
spaces. Most of the proposed splitting methods in the literature have been proposed
for the sum of maximal monotone and inverse-strongly monotone operators in Hilbert
spaces. In this paper, we consider splitting methods for finding zeros of the
sum of maximal monotone operators and Lipschitz continuous monotone operators
in Banach spaces. We obtain weak and strong convergence results for the zeros
of the sum of maximal monotone and Lipschitz continuous monotone operators in
Banach spaces. Many already studied problems in the literature can be considered
as special cases of this paper.

text: There is increasing evidence that both mechanical and biochemical signals
play important roles in development and disease. The development of complex organisms,
in particular, has been proposed to rely on the feedback between mechanical and
biochemical patterning events. This feedback occurs at the molecular level via
mechanosensation but can also arise as an emergent property of the system at the
cellular and tissue level. In recent years, dynamic changes in tissue geometry,
flow, rheology, and cell fate specification have emerged as key platforms of mechanochemical
feedback loops in multiple processes. Here, we review recent experimental and
theoretical advances in understanding how these feedbacks function in development
and disease.

text: 'The effective large-scale properties of materials with random heterogeneities
on a small scale are typically determined by the method of representative volumes:
a sample of the random material is chosen—the representative volume—and its effective
properties are computed by the cell formula. Intuitively, for a fixed sample size
it should be possible to increase the accuracy of the method by choosing a material
sample which captures the statistical properties of the material particularly
well; for example, for a composite material consisting of two constituents, one
would select a representative volume in which the volume fraction of the constituents
matches closely with their volume fraction in the overall material. Inspired by
similar attempts in materials science, Le Bris, Legoll and Minvielle have designed
a selection approach for representative volumes which performs remarkably well
in numerical examples of linear materials with moderate contrast. In the present
work, we provide a rigorous analysis of this selection approach for representative
volumes in the context of stochastic homogenization of linear elliptic equations.
In particular, we prove that the method essentially never performs worse than
a random selection of the material sample and may perform much better if the selection
criterion for the material samples is chosen suitably.'

text: 'Cell polarity is crucial for the coordinated development of all multicellular
organisms. In plants, this is exemplified by the PIN-FORMED (PIN) efflux carriers
of the phytohormone auxin: The polar subcellular localization of the PINs is instructive
to the directional intercellular auxin transport, and thus to a plethora of auxin-regulated
growth and developmental processes. Despite its importance, the regulation of
PIN polar subcellular localization remains poorly understood. Here, we have employed
advanced live-cell imaging techniques to study the roles of microtubules and actin
microfilaments in the establishment of apical polar localization of PIN2 in the
epidermis of the Arabidopsis root meristem. We report that apical PIN2 polarity
requires neither intact actin microfilaments nor microtubules, suggesting that
the primary spatial cue for polar PIN distribution is likely independent of cytoskeleton-guided
endomembrane trafficking.'
