text: 'Concurrent sets with range query operations are highly desirable in applications
such as in-memory databases. However, few set implementations offer range queries.
Known techniques for augmenting data structures with range queries (or operations
that can be used to build range queries) have numerous problems that limit their
usefulness. For example, they impose high overhead or rely heavily on garbage
collection. In this work, we show how to augment data structures with highly efficient
range queries, without relying on garbage collection. We identify a property of
epoch-based memory reclamation algorithms that makes them ideal for implementing
range queries, and produce three algorithms, which use locks, transactional memory
and lock-free techniques, respectively. Our algorithms are applicable to more
data structures than previous work, and are shown to be highly efficient on a
large scale Intel system. '

text: The functional role of AMPA receptor (AMPAR)-mediated synaptic signaling between
neurons and oligodendrocyte precursor cells (OPCs) remains enigmatic. We modified
the properties of AMPARs at axon-OPC synapses in the mouse corpus callosum in
vivo during the peak of myelination by targeting the GluA2 subunit. Expression
of the unedited (Ca2+ permeable) or the pore-dead GluA2 subunit of AMPARs triggered
proliferation of OPCs and reduced their differentiation into oligodendrocytes.
Expression of the cytoplasmic C-terminal (GluA2(813-862)) of the GluA2 subunit
(C-tail), a modification designed to affect the interaction between GluA2 and
AMPAR-binding proteins and to perturb trafficking of GluA2-containing AMPARs,
decreased the differentiation of OPCs without affecting their proliferation. These
findings suggest that ionotropic and non-ionotropic properties of AMPARs in OPCs,
as well as specific aspects of AMPAR-mediated signaling at axon-OPC synapses in
the mouse corpus callosum, are important for balancing the response of OPCs to
proliferation and differentiation cues. In the brain, oligodendrocyte precursor
cells (OPCs) receive glutamatergic AMPA-receptor-mediated synaptic input from
neurons. Chen et al. show that modifying AMPA-receptor properties at axon-OPC
synapses alters proliferation and differentiation of OPCs. This expands the traditional
view of synaptic transmission by suggesting neurons also use synapses to modulate
behavior of glia.

text: The release of IgM is the first line of an antibody response and precedes
the generation of high affinity IgG in germinal centers. Once secreted by freshly
activated plasmablasts, IgM is released into the efferent lymph of reactive lymph
nodes as early as 3 d after immunization. As pentameric IgM has an enormous size
of 1,000 kD, its diffusibility is low, and one might wonder how it can pass through
the densely lymphocyte-packed environment of a lymph node parenchyma in order
to reach its exit. In this issue of JEM, Thierry et al. show that, in order to
reach the blood stream, IgM molecules take a specific micro-anatomical route via
lymph node conduits.

text: 'Objective: To report long-term results after Pipeline Embolization Device
(PED) implantation, characterize complex and standard aneurysms comprehensively,
and introduce a modified flow disruption scale. Methods: We retrospectively reviewed
a consecutive series of 40 patients harboring 59 aneurysms treated with 54 PEDs.
Aneurysm complexity was assessed using our proposed classification. Immediate
angiographic results were analyzed using previously published grading scales and
our novel flow disruption scale. Results: According to our new definition, 46
(78%) aneurysms were classified as complex. Most PED interventions were performed
in the paraophthalmic and cavernous internal carotid artery segments. Excellent
neurologic outcome (modified Rankin Scale 0 and 1) was observed in 94% of patients.
Our data showed low permanent procedure-related mortality (0%) and morbidity (3%)
rates. Long-term angiographic follow-up showed complete occlusion in 81% and near-total
obliteration in a further 14%. Complete obliteration after deployment of a single
PED was achieved in all standard aneurysms with 1-year follow-up. Our new scale
was an independent predictor of aneurysm occlusion in a multivariable analysis.
All aneurysms with a high flow disruption grade showed complete occlusion at follow-up
regardless of PED number or aneurysm complexity. Conclusions: Treatment with the
PED should be recognized as a primary management strategy for a highly selected
cohort with predominantly complex intracranial aneurysms. We further show that
a priori assessment of aneurysm complexity and our new postinterventional angiographic
flow disruption scale predict occlusion probability and may help to determine
the adequate number of per-aneurysm devices.'

text: We consider congruences of straight lines in a plane with the combinatorics
of the square grid, with all elementary quadrilaterals possessing an incircle.
It is shown that all the vertices of such nets (we call them incircular or IC-nets)
lie on confocal conics. Our main new results are on checkerboard IC-nets in the
plane. These are congruences of straight lines in the plane with the combinatorics
of the square grid, combinatorially colored as a checkerboard, such that all black
coordinate quadrilaterals possess inscribed circles. We show how this larger class
of IC-nets appears quite naturally in Laguerre geometry of oriented planes and
spheres and leads to new remarkable incidence theorems. Most of our results are
valid in hyperbolic and spherical geometries as well. We present also generalizations
in spaces of higher dimension, called checkerboard IS-nets. The construction of
these nets is based on a new 9 inspheres incidence theorem.
