Existing cross-network node classification methods are mainly proposed for closed-set setting, where the source network and target share exactly same label space. Such a setting is restricted in real-world applications, since might contain additional classes that not present source. In this work, we study more realistic open-set (O-CNNC) problem, contains all known further several target-private unseen Borrowing concept from domain adaptation, defined as an “unknown” class. To address...
Two-dimensional (2D) ferroelectrics has emerged as a promising building block for nonvolatile memory devices. In this work, we demonstrate the out-of-plane ferroelectricity of 2D CuCrP2S6 (CCPS) at room temperature and switchable diode effect in CCPS-based ferroelectric nanodevices. The spontaneous polarization switching hysteresis loops are directly evidenced by piezoresponse force microscopy. intrinsic originates from non-centrosymmetric structure CCPS, which is confirmed optical...
Spin-orbit torque-induced perpendicular magnetization switching has attracted much attention due to the advantages of nonvolatility, high density, infinite read/write counts, and low power consumption in spintronic applications. To achieve field-free deterministic magnetization, additional magnetic field, layer assistance, or artificially designed structural symmetry breaking are usually required, which not conducive high-density integration application low-power devices. However, 2D Weyl...

Lead-free antiferroelectric AgNbO3 ceramics have garnered extensive attention due to their rapid charge/discharge capabilities and environmentally friendly nature, holding immense potential for energy storage applications. However, the practical utilization of has been hindered by its low density. This study employed an A/B-site co-doping strategy, which yielded positive effects on performance ceramics. By modifying A/B-sites with equivalent amounts Bi3+ Y3+ ions, enhanced maximum...
Spin–orbit torque provides an efficient way to achieve switching of perpendicular magnetization, which is essential for designing energy-efficient spintronic devices. An in-plane antidamping combined with out-of-plane can often deterministically switch magnetization without external magnetic field. Encouragingly, field-free a two-dimensional (2D) material WTe2/ferromagnet bilayer has been reported recently, but the working temperature (< 200 K) quite below room temperature. Here, we...
Reachability query asks whether a vertex can reach another on large directed graphs. It is one of the most fundamental graph operators and has attracted many researchers to study it. Although there are approaches solving this problem, it still remains challenging problem when comes leverage three main costs: index construction time, size, time dense In paper, we propose High Dimension Graph Labeling approach answer reachability queries. First, recursively partition into disjoint non-shared...
Two-dimensional van der Waals ferroelectrics with in-plane polarization are less vulnerable to the depolarization field effect, making them practically more favorable in device applications. Herein, symmetric planar memristor based on two-dimensional WO2Cl2 was fabricated and electrically characterized, showing significant memory effect a current ON/OFF ratio up 104 stable switching cycles. Both short-term plasticity long-term potentiation were observed synaptic simulations by applying...
Recently, the noncollinear magnetic structure with varying Co/Zn ratios was reported in W-type hexaferrites using neutron powder diffraction. It is believed that these spin orderings may stimulate magnetoelectric (ME) effect hexaferrite. Herein, we present distinct evidence of ME response through systematic investigation on and ferroelectric properties BaCoFe17O27. Magnetization exhibits two different anomalies at TC1 ∼ 350 K TC2 150 K, indicating formation long-range longitudinal...
Reachability queries ask whether a vertex can reach another on large directed graphs. It is one of the most fundamental graph operators and has attracted researchers in both academics industry to study it. The main technical challenge support fast reachability by efficient managing three costs: index construction time, size query processing time large/small sparse/dense As real world graphs grow bigger size, these problems remain open challenges that demand high performance solutions. In...
The oxides of iron immersed in hydrochloric acid and anti-oxidation inhibitor have been studied by conversion electron Mössbauer spectroscopy (CEMS). In acid, the formed are β-FeOOH γ-FeOOH, latter being predominant. presence slows down oxidation rate. better inhibition ability, slower progress air. mechanism will be discussed.
