Inclusive Jet and Hadron Suppression in a Multi-Stage Approach
We present a new study of jet interactions in the Quark-Gluon Plasma created
in high-energy heavy-ion collisions, using a multi-stage event generator within
the JETSCAPE framework. We focus on medium-induced modifications in the rate of
inclusive jets and high transverse momentum (high-) hadrons.
Scattering-induced jet energy loss is calculated in two stages: A high
virtuality stage based on the MATTER model, in which scattering of highly
virtual partons modifies the vacuum radiation pattern, and a second stage at
lower jet virtuality based on the LBT model, in which leading partons gain and
lose virtuality by scattering and radiation. Coherence effects that reduce the
medium-induced emission rate in the MATTER phase are also included. The
\trento\ model is used for initial conditions, and the (2+1)D VISHNU model is
used for viscous hydrodynamic evolution. Jet interactions with the medium are
modeled via 2-to-2 scattering with Debye screened potentials, in which the
recoiling partons are tracked, hadronized, and included in the jet clustering.
Holes left in the medium are also tracked and subtracted to conserve transverse
momentum. Calculations of the nuclear modification factor ()
for inclusive jets and high- hadrons are compared to
experimental measurements at RHIC and the LHC. Within this framework, we find
that two parameters for energy-loss, the coupling in the medium and the
transition scale between the stages of jet modification, suffice to
successfully describe these data at all energies, for central and semi-central
collisions, without re-scaling the jet transport coefficient .Comment: 33 pages, 23 figure
Multi-scale evolution of charmed particles in a nuclear medium
Parton energy-momentum exchange with the quark gluon plasma (QGP) is a
multi-scale problem. In this work, we calculate the interaction of charm quarks
with the QGP within the higher twist formalism at high virtuality and high
energy using the MATTER model, while the low virtuality and high energy portion
is treated via a (linearized) Boltzmann Transport (LBT) formalism. Coherence
effect that reduces the medium-induced emission rate in the MATTER model is
also taken into account. The interplay between these two formalisms is studied
in detail and used to produce a good description of the D-meson and charged
hadron nuclear modification factor RAA across multiple centralities. All
calculations were carried out utilizing the JETSCAPE framework
Intravitreal injection of anti-vascular endothelial growth factor agents for ocular vascular diseases: Clinical practice guideline
Purpose: To provide the clinical recommendations for the administration of intravitreal anti-vascular endothelial growth factor (VEGF) drugs especially bavacizumab for ocular vascular diseases including diabetic macular edema, neovascular age-related macular degeneration, myopic choroidal neovascularization, retinal vein occlusion and central serous chorioretinopathy. Methods: Twenty clinical questions were developed by the guideline technical committee. Relevant websites and databases were searched to find out the pertinent clinical practice guidelines to answer the questions. The technical committee provided possible answers (scenarios) according to the available evidences for each question. All scenarios along with their levels of evidence and the supported articles were sent to the experts for external review. If the experts did not agree on any of the scenarios for one particular clinical question, the technical committee reviewed all scenarios and their pertinent evidences and made the necessary decision. After that, the experts were asked to score them again. All confirmed scenarios were gathered as the final recommendations. Results: All the experts agreed on at least one of the scenarios. The technical committee extracted the agreed scenario for each clinical question as the final recommendation. Finally, 56 recommendations were developed for the procedure of intravitreal anti-VEGF injection and their applications in the management of ocular vascular diseases. Conclusion: The implementation of this guideline can standardize the management of the common ocular vascular diseases by intravitreal injection of anti-VEGF agents. It can lead to better policy-making and evidence-based clinical decision by ophthalmologists and optimal evidence based eye care for patients. © 2018 Journal of Ophthalmic and Vision Research

Advances and Open Problems in Federated Learning
Federated learning (FL) is a machine learning setting where many clients
(e.g. mobile devices or whole organizations) collaboratively train a model
under the orchestration of a central server (e.g. service provider), while
keeping the training data decentralized. FL embodies the principles of focused
data collection and minimization, and can mitigate many of the systemic privacy
risks and costs resulting from traditional, centralized machine learning and
data science approaches. Motivated by the explosive growth in FL research, this
paper discusses recent advances and presents an extensive collection of open
problems and challenges.Comment: Published in Foundations and Trends in Machine Learning Vol 4 Issue
