Use of High-Frequency In-Home Monitoring Data May Reduce Sample Sizes Needed in Clinical Trials by Dodge, Hiroko H., Zhu, Jian, Mattek, Nora C., Austin, Daniel, Kornfeld, Judith, Kaye, Jeffrey A.

“…CONCLUSIONS: Individual-specific thresholds of low functional performance based on high-frequency in-home monitoring data distinguish trajectories of MCI from NC and could substantially reduce sample sizes needed in dementia prevention RCTs.…”

Trends of pH decrease in the Mediterranean Sea through high frequency observational data: indication of ocean acidification in the basin by Flecha, Susana, Pérez, Fiz F., García-Lafuente, Jesús, Sammartino, Simone, Ríos, Aida. F., Huertas, I. Emma

“…We document a remarkable decreasing annual trend of −0.0044 ± 0.00006 in the Mediterranean pH, which can be interpreted as an indicator of acidification in the basin based on high frequency records. Modeling pH data of the Mediterranean outflow allowed to discriminate between the pH values of its two main constituent water masses, the Levantine Intermediate Water (LIW) and the Western Mediterranean Deep Water (WMDW). …”

Impact of Data Processing and Antenna Frequency on Spatial Structure Modelling of GPR Data by De Benedetto, Daniela, Quarto, Ruggiero, Castrignanò, Annamaria, Palumbo, Domenico A.

“…The results showed that the type and range of spatial structures of GPR data did not depend on data processing at a given frequency. …”

High-frequency, precise modification of the tomato genome by Čermák, Tomáš, Baltes, Nicholas J., Čegan, Radim, Zhang, Yong, Voytas, Daniel F.

“…Even though donor molecules were replicated in the vectors, no evidence was found of persistent extra-chromosomal replicons or off-target integration of T-DNA or replicon sequences. CONCLUSIONS: High-frequency, precise modification of the tomato genome was achieved using geminivirus replicons, suggesting that these vectors can overcome the efficiency barrier that has made gene targeting in plants challenging. …”

Magnetoencephalography Detection of High-Frequency Oscillations in the Developing Brain by Leiken, Kimberly, Xiang, Jing, Zhang, Fawen, Shi, Jingping, Tang, Lu, Liu, Hongxing, Wang, Xiaoshan

“…To determine if the high-frequency neuromagnetic signals are true brain responses in high-frequency range, we analyzed the MEG data using the conventional averaging as well as newly developed time-frequency analysis along with beamforming. …”

Detection of Successful and Unsuccessful Pregnancies in Mice within Hours of Pairing through Frequency Analysis of High Temporal Resolution Core Body Temperature Data by Smarr, Benjamin L., Zucker, Irving, Kriegsfeld, Lance J.

“…Application of wavelet analysis that permits frequency analysis while preserving temporal resolution, uncovers significant differences in ultradian frequencies of CBT; these rhythms are significantly increased in the 12 h after the day of pairing for pregnancies carried to term compared to apparent pregnancies that failed. …”

Low-Frequency Fluctuations of the Resting Brain: High Magnitude Does Not Equal High Reliability by Mao, Dewang, Ding, Zhongxiang, Jia, Wenbin, Liao, Wei, Li, Xun, Huang, Huiyuan, Yuan, Jianhua, Zang, Yu-Feng, Zhang, Han

“…The amplitude of low-frequency fluctuation (ALFF) measures low-frequency oscillations of the blood-oxygen-level-dependent signal, characterizing local spontaneous activity during the resting state. …”

Big data integration shows Australian bush-fire frequency is increasing significantly by Dutta, Ritaban, Das, Aruneema, Aryal, Jagannath

“…In this study, we develop an ensemble method based on a two-layered machine learning model to establish relationship between fire incidence and climatic data. In a 336 week data trial, we demonstrate that the model provides highly accurate bush-fire incidence hot-spot estimation (91% global accuracy) from the weekly climatic surfaces. …”

Systematic Review of the Exposure Assessment and Epidemiology of High-Frequency Voltage Transients by de Vocht, Frank, Olsen, Robert G.

“…It has been proposed that an explanation could be that high-frequency voltage transients [dirty electricity (DE)] which are superimposed on 50/60-Hz fields, but are generally not measured, are the real causal agent. …”
