How Old Are You Now?
In lieu of an abstract, below is the essay\u27s first paragraph.
She struggled to her feet, mind clouded with bewilderment. It was nothing new to her. Same scene every morning or day, what ever time it was when she came to. It became her routine- at night fade to unconsciousness feeling found, in the morning wake to the sting of reality feeling terribly lost. Today was different. Today the sting hurt more, today she needed a change. It is her birthday
Critique and the Idea of Translation
This issue of de genere invites us to reflect on the following question: How can
translation contribute to the pursuit of a more inclusive culture that is invested in
undoing hierarchies and favoring plurality? My article considers the metaphorical
potential of translation for critique. It discusses the notion of translation as a
movement of ideas across disciplinary borders, using as a case study the border
between philosophy and theory as it is interrogated in the work and career of Fredric
Jameson
Between Suspicion and Love: Reality, Postcritique and Euro-American Modernization (An Introduction to the Debate)
The essay introduces major tenets in the current debate on postcritique, focusing especially on the widespread rejection of symptomatic reading in literary studies and on the rejection of rupture as both a modernist and theoretical model for the conception of the new. Further, it presents theory as a phase of Euro-American modernization. The aim of the article is to outline a wider, more dynamic concept of critique, understood as a movement of intellectual—and geographical—displacements
Data Augmentation for Manipulation
The success of deep learning depends heavily on the availability of large
datasets, but in robotic manipulation there are many learning problems for
which such datasets do not exist. Collecting these datasets is time-consuming
and expensive, and therefore learning from small datasets is an important open
problem. Within computer vision, a common approach to a lack of data is data
augmentation. Data augmentation is the process of creating additional training
examples by modifying existing ones. However, because the types of tasks and
data differ, the methods used in computer vision cannot be easily adapted to
manipulation. Therefore, we propose a data augmentation method for robotic
manipulation. We argue that augmentations should be valid, relevant, and
diverse. We use these principles to formalize augmentation as an optimization
problem, with the objective function derived from physics and knowledge of the
manipulation domain. This method applies rigid body transformations to
trajectories of geometric state and action data. We test our method in two
scenarios: 1) learning the dynamics of planar pushing of rigid cylinders, and
2) learning a constraint checker for rope manipulation. These two scenarios
have different data and label types, yet in both scenarios, training on our
augmented data significantly improves performance on downstream tasks. We also
show how our augmentation method can be used on real-robot data to enable more
data-efficient online learning.Comment: Robotics Science and Systems (RSS) 2022 Project Website:

Anisotropic compression in the high pressure regime of pure and Cr-doped vanadium dioxide
We present structural studies of VCrO (pure, 0.7% and 2.5% Cr
doped) compounds at room temperature in a diamond anvil cell for pressures up
to 20 GPa using synchrotron x-ray powder diffraction. All the samples studied
show a persistence of the monoclinic symmetry between 4 and 12 GPa. Above
12 GPa, the monoclinic symmetry changes to isostructural phase
(space group ) with a significant anisotropy in lattice compression of
the - plane of the phase. This behavior can be reconciled
