One of the key technologies to support mobility of mobile station (MS) in mobile communication systems is location management which consists of location update and paging. In this paper, an improved movement-based location management scheme with two movement thresholds is proposed, considering bursty data traffic characteristics of packet-switched (PS) services. The analytical modeling for location update and paging signaling loads of the proposed scheme is developed thoroughly and the performance of the proposed scheme is compared with that of the conventional scheme. We show that the proposed scheme outperforms the conventional scheme in terms of total signaling load with an appropriate selection of movement thresholds.

The proliferation of cyanobacteria has become a significant water management challenge due to the increasing eutrophication of water supply reservoirs. Cyanobacterial blooms thrive on elevated nutrient concentrations and form extensive green mats, disrupting the local ecosystem. Furthermore, many cyanobacterial species can produce toxins that are lethal to vertebrates called cyanotoxins.

Purpose: To address the extent to which Federally Qualified Health Centers (FQHCs) and independent and provider-based Rural Health Clinics (RHCs) were using telehealth prior to and during the COVID-19 pandemic.
Methods: A nationally representative 5% sample of Medicare Fee-for-Service beneficiaries who used outpatient services at FQHCs and RHCs were identified within the 2019-2021 5% Medicare Limited Data Set Outpatient and Carrier files. Rural-Urban Continuum Codes were used to identify rural-urban clinic locations.
