Not in My Backyard! Temporal Voting Over Public Chores Open
We study a temporal voting model where voters have dynamic preferences over a set of public chores---projects that benefit society, but impose individual costs on those affected by their implementation. We investigate the computational com…

TH-iSSD: Design and Implementation of a Generic and Reconfigurable Near-Data Processing Framework Open
We present the design and implementation of TH-iSSD, a near-data processing framework to address the data movement problem. TH-iSSD does not pose any restriction to the hardware selection and is highly reconfigurable—its core components, s…

Meta-Analysis of the Efficacy and Safety of Tranexamic Acid in Spinal Surgery Open
Objective. The safety and effectiveness of topical tranexamic acid in spinal surgery has not yet been reached, and further research is needed to confirm it. This study is aimed at detecting the effectiveness and safety on the tranexamic ac…

Plor: General Transactions with Predictable, Low Tail Latency Open
We present pessimistic locking and optimistic reading (PLOR), a hybrid concurrency control protocol for in-memory transaction systems that delivers high throughput and low tail latency. PLOR is especially designed for high-contention workl…

Quantization for biharmonic maps from non-collapsed degenerating Einstein 4-manifolds Open
For a sequence of extrinsic or intrinsic biharmonic maps $u_j: M_j\rightarrow N$ from a sequence of non-collapsed degenerating closed Einstein 4-manifolds $(M_j,g_j)$ with bounded Einstein constants, bounded diameters and bounded $L^2$ cur…

Temporal-Spatial Analysis of the Warming Effect of Different Cultivated Land Urbanization of Metropolitan Area in China Open
The regional warming effect is different when different cultivated land types are converted into urban construction land, while its temporal and spatial changes are unclear. We studied the temporal and spatial changes in the warming effect…

Kernel/User-level Collaborative Persistent Memory File System with Efficiency and Protection Open
Emerging high performance non-volatile memories recall the importance of efficient file system design. To avoid the virtual file system (VFS) and syscall overhead as in these kernel-based file systems, recent works deploy file systems dire…

Uniqueness of tangent cone for biharmonic map with isolated singularity Open
In this paper, we study the problem of uniqueness of tangent cone for minimizing extrinsic biharmonic maps. Following the celebrated result of Simon, we prove that if the target manifold is a compact analytic submanifold in R p and if ther…

On expansions of Ricci flat ALE metrics in harmonic coordinates about the infinity Open
In this paper, we study the expansions of Ricci flat metrics in harmonic coordinates about the infinity of ALE (asymptotically local Euclidean) manifolds.

Machine vision based in-process light-emitting diode chip mounting system Open
Background: In this study, a machine vision–based method was developed for automated in-process light-emitting diode chip mounting lines with position uncertainty. In order to place the tiny light-emitting diode chips on the pattern of a p…

The effects of 1.5 and 2 degrees of global warming on Africa in the CORDEX ensemble Open
There is a general lack of information about the potential effects of 1.5, 2 or more degrees of global warming on the regional climates within Africa, and most studies that address this use data from coarse resolution global models. Using …

Impact of Land-Use and Land-Cover Change on Meteorology in the Beijing–Tianjin–Hebei Region from 1990 to 2010 Open
Land use and land cover (LULC) in the Beijing–Tianjin–Hebei region has changed significantly since 1990. To comprehensively understand its impact on meteorology, this paper uses an LULC transfer matrix to discuss changes 10 years before th…
