Contributions of the Alzheimer's Disease Neuroimaging Initiative to advancing AD research: a targeted review of recent publications

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently celebrated its 20th anniversary, reflecting two decades of major contributions to Alzheimer's research through open data sharing and longitudinal multimodal assessments. This review synthesizes 122 high‐impact studies using ADNI data or biospecimens from 2023 to mid‐2025 to ...

CDR-To-MoVis: Developing a Mobility Visualization System from CDR data

2015 IEEE 31st International Conference on Data Engineering, 2015
CDR (Call Detail Records) data is more easily available than other network related data (such as GPS data) as most telecommunications service providers (TSPs) maintain such data. By analyzing it one can find mobility patterns of most of the population thus leading to efficient urban planning, disease and traffic control, etc. But its granularity is low

Partial CDR database dimensioning

Telecommunication Systems, 2011
Novel services in the mobile telecommunication era are far more longer then a few years ago when the price of the call was calculated purely on the length of the session. To overcome possible fraud issues, the corresponding standards are defining partial CDRs that are sent to the billing system periodically during the sessions.

On the impact of channel loss on CDR locking

2016 IEEE 59th International Midwest Symposium on Circuits and Systems (MWSCAS), 2016
This paper shows that under certain conditions of incoming jitter in clock and data recovery circuits (CDR), the bang-bang phase detector (BBPD) gain can rise even for increments in the channel loss. Even more, it is shown how the BBPD gain can increase when sinusoidal and uniform jitter noise are combined; impacting on the CDR dynamic response.

Gradient Coating of Polydopamine via CDR

Langmuir, 2017
Surfaces with gradient properties are of central importance for a number of chemical and biological processes. Here, we report rapid generation of a polydopamine (PDA) gradient on hydrophobic surfaces by a simple, low cost, and general technology, cyclic draining-replenishing (CDR).

Improving CDR Performance via Estimation

2006 IEEE International Solid State Circuits Conference - Digest of Technical Papers, 2006
A dual-loop CDR can be viewed as a simple phase-estimator. Different estimators can be built by changing the phase DAC control logic. Three different 0.13mum estimators for a 3Gb/s serial link are presented. These estimators address dual-loop CDR limitations including lock time, frequency range, and jitter tolerance in non-mesochronous ...

Passing the CDR Exam

Nutrition Today
This study investigated the characteristics and confidence of dietitians who passed the Commission on Dietetic Registration examination to become registered dietitians (RDs). In this descriptive study, data were collected using Qualtrics. A survey link was distributed to dietetics program directors, posted on RD Facebook groups, and distributed through
