Abstract A cobaltaelectro‐catalyzed dehydrogenative [4+2] annulation of arylphosphinamides with alkynes was proposed in the present study to selectively construct a range cyclic phosphinamide derivatives. Picolinic acid acted as ligand promote this transformation. total 38 examples demonstrated broad substrate scope, sufficient functional tolerance and excellent regioselectivity. Moreover, no additional oxidants electrolytes were needed it possible achieve gram scale synthesis, late‐stage...
Barrier coverage problem is one of hot research topics in directional sensor networks (DSNs). Directional sensors could zoom their sensing ranges, within which the event detection probability decreases with increase distance between location and sensor. Although that an detected by a single may be below required criteria, achieved jointly two can above criteria. In this work, we study barrier DSNs, taking into account nodes' ability adjusting working directions ranges. We mainly propose...

This cyclization proceeded transition metal- oxidant-free conditions generated H2 as only byproduct. Additionally, gram-scale reactions broad substrate scope demonstrated the synthetic usefulness this protocol.
Federated learning (FL) enables resource-constrained node devices to learn a shared model while keeping the training data local. Since recent research has demonstrated multiple privacy leakage attacks in FL, e.g., gradient inference and membership attacks, differential (DP) is applied serve as one of most effective protection mechanisms. Despite benefit DP brings, we observe that introduction also brings random changes client updates, which will affect robust aggregation algorithms. We...
With the development of deep learning processors and accelerators, models have been widely deployed on edge devices as part Internet Things. Edge device are generally considered valuable intellectual properties that worth for careful protection. Unfortunately, these a great risk being stolen or illegally copied. The existing model protections using encryption algorithms suffered from high computation overhead which is not practical due to limited computing capacity devices. In this work, we...
