Modulating Image Restoration with Continual Levels via Adaptive Feature Modification Layers
In image restoration tasks, like denoising and super resolution, continual
modulation of restoration levels is of great importance for real-world
applications, but has failed most of existing deep learning based image
restoration methods. Learning from discrete and fixed restoration levels, deep
models cannot be easily generalized to data of continuous and unseen levels.
This topic is rarely touched in literature, due to the difficulty of modulating
well-trained models with certain hyper-parameters. We make a step forward by
proposing a unified CNN framework that consists of few additional parameters
than a single-level model yet could handle arbitrary restoration levels between
a start and an end level. The additional module, namely AdaFM layer, performs
channel-wise feature modification, and can adapt a model to another restoration
level with high accuracy. By simply tweaking an interpolation coefficient, the
intermediate model - AdaFM-Net could generate smooth and continuous restoration
effects without artifacts. Extensive experiments on three image restoration
tasks demonstrate the effectiveness of both model training and modulation
testing. Besides, we carefully investigate the properties of AdaFM layers,
providing a detailed guidance on the usage of the proposed method.Comment: Accepted by CVPR 2019 (oral); code is available:

MOGU LI STRUKTURALNE PRILAGODBE VLADINOG UPRAVLJANJA POBOLJÅ ATI EKONOMSKE UÄINKE? SLUÄAJ WUHANSKOG VELEGRADSKOG PODRUÄJA U KINI
The paper employs M-form and U-form organization theory to analyze the structural innovation
of government governance, and tries to study the resources integration and economic
performances among different cities in a metropolis circle by using the example of Wuhan
metropolis circle in China. Specifically, we focus on analyzing the difference between economic
performance before and after the formation of Wuhan metropolis circle. The research result
shows that, on the one hand, the formation of Wuhan metropolis circle can make full use of the
U-form organization; on the other hand, different cities also benefit from coordinated regional
development and rational resources allocation thanks to the formation of metropolis circle.
Furthermore, each city has individual characteristics and complementary to other cities.
Consequently, the economic performance of theses cities greatly differs from each other.Rad koristi organizacijsku teoriju M-forme i U-forme za analizu strukturalnih inovacija vladinog
upravljanja, te pokuÅ”ava prouÄiti integraciju resursa i ekonomske uÄinke vladinog upravljanja
meÄu raznim gradovima velegradskog podruÄja koristeÄi primjer wuhanskog velegradskog
podruÄja u Kini. Posebno je usredotoÄen na analizu razlike izmeÄu ekonomskih uÄinaka prije i
nakon stvaranja wuhanskog velegradskog podruÄja. Rezultati istraživanja pokazuju da, s jedne
strane, stvaranje wuhanskog velegradskog podruÄja može u potpunosti iskoristiti U-formu
organizacije, dok s druge strane, razliÄiti gradovi takoÄer profitiraju radi koordiniranog
podruÄnog razvoja i racionalne raspodjele resursa zahvaljujuÄi stvaranju velegradskog
podruÄja. Osim toga, svaki grad ima individualne karakteristike i one komplementarne drugim
gradovima. Stoga se ekonomski uÄinci ovih gradova uvelike razlikuju jedni od drugih
Exploration of the CU-MN-AS ternary phase diagram and MN3B4 antiferromagnets
CuMnAs was first studied more than fifty years ago, both in a tetragonal phase (t-CuMnAs) and orthorhombic phase (o-CuMnAs). Today, the prospect of spintronics has created a new focus on antiferromagnetic materials with NeĢel temperatures above room temperature, with the goal of reading and writing spin orientations by electrical current. Tetragonal CuMnAs is a candidate whose experimental reading and writing with electrical field has been realized as a proof of concept. Our fundamental knowledge of other phases in the Cu-Mn-As ternary system remains to be improved. In this study, we study a broader part of the phase diagram of this system. We examine the structure of different phases, their thermal and magnetic properties, and the relationship between stoichiometry and structure. We also present our synthetic and magnetic characterization of antiferromagnetic Mn3B4. Single crystals larger than 200 microns were obtained and examined by single-crystal diffraction and magnetometry
Consumption and savings of migrants in China ā social cohesion perspective
Boosting domestic demand is the task of Chinaās sustainable economic development, and in particular, China has become an
important global consumer market and the savings patterns
should be more cohesive and without discriminations. Using data
of China Migrants Dynamic Survey, the paper provides new evidence on internal migrantsā savings in China from the perspective
of homeownership and family migration. We find that migrantsā
savings are 5.25ā6.60 percentage points higher than hukou population even when controlling for working, social status, and social
insurance coverage which means the migrant will save
1019.88ā1647.10 yuan in 2010 price more monthly. Furthermore,
we discover housing could partly explain the saving gap, while
when we take remittance and family migration into account, the
saving rate differences between migrants and hukou population
disappears, which means migrants may save to consume when
they go back to their hometown with their family members
instead of consuming later in the resident cities. The research is
carried out taking into account the objectives of social cohesion
policy identified at national and international level and their
involvement in consumption and saving processes. Our empirical
results reveal that homeownership, remittance motive and family
migration play important roles in shaping saving behaviour
of migrants
