Synchronized stochastic gradient descent (SGD) optimizers with data parallelism are widely
used in training large-scale deep neural networks. Although using larger mini-batch sizes …

Sodium-ion batteries (SIBs) are one of the most promising alternatives to lithium-ion batteries
(LIBs), due to the much more abundant resources of Na compared with Li in the world. …

Sodium metal batteries are attracting increasing attention on account of their high energy
densities as well as the abundance of sodium-based resources. However, the uneven metallic …

Library-based record and replay tools aim to reproduce an application’s execution by recording
the results of selected functions in a log and during replay returning the results from the …

Testing large-scale distributed systems is a challenge, because some errors manifest themselves
only after a distributed sequence of events that involves machine and network failures. …

Batched stream processing is a new distributed data processing paradigm that models
recurring batch computations on incrementally bulk-appended data streams. The model is …

Solution processing of semiconductors is highly promising for the high-throughput production
of cost-effective electronics and optoelectronics. Although hybrid perovskites have …

While quasi‐two‐dimensional (quasi‐2D) perovskites have emerged as promising
semiconductors for light‐emitting diodes (LEDs), the broad‐width distribution of quantum wells …

Sodium‐ion batteries as a prospective alternative to lithium‐ion batteries are facing the
challenge of developing high‐performance, low‐cost and sustainable anode materials. Hard …

In inverted perovskite solar cells (PSCs), the fullerene derivative [6,6]-phenyl-C 61 -butyric
acid methyl ester (PCBM) is a widely used electron transport material. However, a high …
