Proactive caching in base station (BS) is a promising way to leverage the human-behavior related information boost system throughput and improve user experience with low cost. Yet existing policies are "blind" users, i.e., users unaware about whether files be requested locally cached at BS around them, whose performance will degrade mobile systems due randomness of behavior. For example, when stays cell where caches file later, may not initiate request. When sends request, it have entered...

Abstract Time‐stretch spectroscopy is a powerful tool for studying transient and nonrepetitive physical events. Its extension to the fundamental molecular fingerprint region promising chemical biological research but encounters difficulties in mid‐infrared photodetection strong attenuation of aqueous environments. Here, time‐stretch via coincidently‐pumped nonlinear frequency conversion efficient generation detection demonstrated. Broadband (≈200 cm −1 ) spectra at 77.5 Mspectra s with high...
Recent years have witnessed a widespread increase of interest in network representation learning (NRL). By far most research efforts focused on NRL for homogeneous networks like social where vertices are the same type, or heterogeneous knowledge graphs (and/or edges) different types. There has been relatively little dedicated to bipartite networks. Arguably, generic embedding methods node2vec and LINE can also be applied learn vertex embeddings by ignoring type information. However, these...
We report a passive stabilization of the repetition rate for mode-locked fiber laser by using an electro-optic modulator in phase-biased nonlinear amplifying loop mirror. The underlying mechanism, contrast to active feedback operations, lies cross-phase modulation between electrical and optical pulses within crystal. resulting spectral shift can automatically compensate cavity-length drift via group velocity dispersion. Consequently, artificial actuator enables capture range up 2.3 mm, much...
Abstract Urban rivers are significant hotspots of CO 2 emissions into the atmosphere, playing important roles in global carbon emission inventories. However, little is known about effect ecological restoration on dynamics severely polluted urban rivers, and this strongly hindering our understanding positive effects human activities urbanized aquatic ecosystems. We measured partial pressure ( p ) fluxes nine with varying degrees restoration, assessed relationships water physicochemical...
Interference neutralization (IN) is a new interference management mechanism found from and inherent in networks with relays. In this paper, we study the feasibility of IN for relay-aided multi-input-multi-output (MIMO) broadcast channel (MIMO-IBC) without symbol extension. Assuming linear transceiver multiple amplify-and-forward relays, consider fully connected symmetric systems, where each base station (BS), relay, user equipped antennas, desires data streams. We first present necessary...
In multiuser relay systems, if the does not have sufficient degrees of freedom to eliminate interference, spectral efficiency gain two-way (TWR) transmission may vanish. Signal alignment (SA) signaling is possible recover this but suffer from a signal power loss. To improve multicarrier code-division multiple-access (MC-CDMA) TWR we develop an equivalent SA (ESA) procedure. Simply by aligning received symbols after despreading instead signals as in signaling, ESA has more feasible solutions...
Rivers have been largely considered as the source of nitrous oxide (N 2 O) to atmosphere. N O emissions from rivers could be seriously influenced by damming and exhibit unique spatiotemporal patterns in river-reservoir systems. Multiple research studies report with single reservoirs, but controls cascaded system remain unclear. In this study, we investigated variations concentrations fluxes along a cascade river (Wubu River) Southwest China. Our results showed that Wubu River ranged 2.5...
Dual-wavelength mode-locked fiber lasers have attracted great attention due to their enormous potential in facilitating dual-comb spectroscopy. However, mechanism for dual-wavelength dissipative soliton mode-locking and the intracavity dynamics are still elusive. In this paper, we construct a simple universal model numerically investigate buildup of an all-normal dispersion laser. By resolving pulses evolution interactions, find that chromatic induced pulse collision plays important role...
At present, wireless sensor networks (WSNs) play an important role in collecting and processing information smart transportation monitoring. Inevitably, the performance of resource scheduling algorithm directly determines quality service WSNs. In this paper, we present a novel large-scale WSNs based on differential ion coevolution multi-objective decomposition (DIC-MOD) to optimize We first introduce certain number mobile nodes with higher configuration into consider them as relay strengthen...
In this paper, we analyze in a unified way the achievable rate and spectral efficiency of multicarrier multiantenna two-hop relay systems with an interference-free linear transceiver. We consider two kinds decode-and-forward (DF) three nodes. first kind where only node employs full channel state information (CSI) both source–relay (S–R) link (first hop) relay–destination (R–D) (second hop), eliminates interference these links. second systems, source CSI hop, destination whereas hops; nodes...
Dual‐wavelength mode‐locking lasers delivering asynchronous dual‐color solitons are excellent sources for dual‐comb spectroscopies. Up to now, diverse approaches have been developed implement dual‐wavelength lasers. However, the buildup dynamics of not well revealed. Here, by means time‐stretch dispersive Fourier transform technique, real‐time observation process and propagation in a mode‐locked fiber laser reported. In addition typical phases that discussed on conventional solitons, such as...
Programming-based Pre-trained Language Models (PPLMs) such as CodeBERT have achieved great success in many downstream code-related tasks. Since the memory and computational complexity of self-attention Transformer grow quadratically with sequence length, PPLMs typically limit code length to 512. However, codes real-world applications are generally long, searches, which cannot be processed efficiently by existing PPLMs. To solve this problem, paper, we present SASA, a Structure-Aware Sparse...
