Performance Comparison of NB-Fi, Sigfox, and LoRaWAN.

LPWANs are a promising solution for wireless sensor networks. To compete with such widespread technologies as LoRaWAN and Sigfox, recently a new LPWAN technology called NB-Fi has been developed. In a short time, many NB-Fi networks have been deployed in various countries.

Patterns of Intimate Partner Violence Victimization and Survivors' Help-Seeking.

Intimate partner violence (IPV) survivors often do not seek critically needed help. A good understanding of the relationship between the pattern of violence and help-seeking is critical to developing adequate services for the survivors, as well as for reaching out to those who do not seek help. This study used the National Intimate Partner and Sexual Violence Survey to examine how IPV survivor's help-seeking varies, depending on the characteristics of the survivors and the pattern of victimization.
