Continuous queries are persistent that allow users to receive new results when they become available. While continuous query systems can transform a passive web into an active environment, need be able support millions of due the scale Internet. No existing have achieved this level scalability. NiagaraCQ addresses problem by grouping based on observation many share similar structures. Grouped common computation, tend fit in memory and reduce I/O cost significantly.

Energy optimization in buildings by controlling the Heating Ventilation and Air Conditioning (HVAC) system is being researched extensively. In this paper, a model-free actor-critic Reinforcement Learning (RL) controller designed using variant of artificial recurrent neural networks called Long-Short-Term Memory (LSTM) networks. Optimization thermal comfort alongside energy consumption goal tuning RL controller. The test platform, our office space, SketchUp. Using OpenStudio, HVAC installed...

The high complexity and dynamics of the microservice architecture make its application diagnosis extremely challenging. Static troubleshooting approaches may fail to obtain reliable model applies for frequently changing situations. Even if we know calling dependency services, lack a more dynamic mechanism due existence indirect fault propagation. Besides, algorithm based on single metric usually identify root cause anomaly, as type is not enough characterize anomalies occur in diverse...

Abstract With the development of energy storage technology, demand for high density and security batteries is increasing, making research lithium battery (LB) technology an extremely important pursuit. However, poor structural stability electrode materials, interfacial impedance between electrolyte electrode, growth dendrites have seriously hindered commercialization LBs. Recently, due to their unique electronic structures hybrid forms, boron‐based materials been widely used in different LB...

Abstract A formidable challenge to achieve the practical applications of rechargeable lithium (Li) metal batteries (RLMBs) is suppress uncontrollable growth Li dendrites. One most effective solutions fabricate anodes with specific crystal plane, but still lack a simple and high‐efficient approach. Herein, facile controllable way for scalable customization polished highly preferred (110) (200) crystallographic orientation (donating as Li(110) Li(200), respectively) by regulating times...

Abstract Immunotherapy is showing good potential for colorectal cancer therapy, however, low responsive rates and severe immune‐related drug side effects still hamper its therapeutic effectiveness. Herein, a highly stable cerasomal nano‐modulator (DMC@P‐Cs) with ultrasound (US)‐controlled delivery capability selective sonodynamic‐immunotherapy fabricated. DMC@P‐Cs’ lipid bilayer self‐assembled from cerasome‐forming (CFL), pyrophaeophorbid conjugated (PL), phospholipids containing unsaturated...

In-Memory Computing (IMC), which takes advantage of analog multiplication-accumulation (MAC) insides memory, is promising to alleviate the Von-Neumann bottleneck and improve energy efficiency deep neural networks (DNNs). Since time-domain (TD) computing also an energy-efficient paradigm, we present 8kb mixed-signal IMC macro, TD-SRAM, by combining with TD computing. A dual-edge single input (DESI) topology proposed, can significantly area power efficiencies cell. The TD-SRAM bitcell...

Generally, computer-science-oriented artificial neural networks (ANNs) and neuroscience-oriented spiking (SNNs) are two main approaches to develop brain-spired non von Neumann computing systems. The goal of exploring complex intelligence (AI) systems demands general neuromorphic hardware platforms compatible with both them. However, as a result the obvious differences in their fundamental mathematical expression coding scheme, many or deep network (DNN) accelerators accommodate only one This...

Untethered soft magnetoresponsive actuators (SMRAs), which can realize rapid shape transformation, have attracted widespread attention for their strategic applications in exploration, transportation, and minimally invasive medicine. It remains a challenge to fabricate SMRAs with complicated morphing modes (more than bending folding), limiting simple shape-morphing locomotion. Herein, method integrating the ancient kirigami art an advanced mechanical assembly is proposed, realizes 2D-to-3D...

We synthesized three 20mer caged circular antisense oligodeoxynucleotides (R20, R20B2 and R20B4) with a photocleavable linker an amide bond between two 10mer oligodeoxynucleotides. With these oligodeoxynucleotides, RNA-binding affinity its digestion by ribonuclease H were readily photomodulated. RNA cleavage rates upregulated ∼43-, 25- 15-fold for R20, R20B4, respectively, upon light activation in vitro. R20B4 2- or 4-nt gaps the target lost their ability to bind even though small amount of...
