The Effects of Pre-Trial Event Stimulus Properties on Timing in the Peak Interval Procedure
… stimuli produce shifts in peak/middle time towards later values, regardless of whether these stimuli are presented prior to or during the timing signal. Although the effects of during-trial stimulus properties—temporal location, duration, and salience—have been previously reported, no …

Low Cost Magnetometer Calibration and Distributed Simultaneous Multipoint Ionospheric Measurements from a Sounding Rocket Platform
… of sounding rockets in recent history: one night-time mid-latitude rocket from Wallops Flight Facility in August 2022 and three mid-latitude rockets from White Sands Missile Range during the October 2023 annular solar eclipse. All rockets had a comprehensive suite of instruments for …

Investigation of Long-Term Prestress Losses in Pretensioned High Performance Concrete Girders
Effective determination of long-term prestress losses is important in the design of prestressed concrete bridges. Over-predicting prestress losses results in an overly conservative design for service load stresses, and under-predicting prestress losses, can result in cracking at service loads. …

Zeit- und konzentrationsabhängige Modulation der VEGF-Genexpression und der VEGF-Proteinmenge durch TNF[alpha] IL-1[beta], IL-6, EGF und TGF-[beta]1 in Ovarialkarzinomzellinien
… little investigated. This study examines the time- and concentration- dependent influence of the cytokines and growth factors TNF-alpha, IL-1beta, IL-6, EGF and TGF- beta 1 in regards to the VEGF- expression of the ovarian cancer cell lines BG-1, HEY and SKOV-3 by northern- analysis and ELISA. …

A factorial approach to the study of alkali-silica reaction in concrete
… to be studied in addition to studying the main effect of each separate factor. The experimental work was carried out in three stages. The first and second stages comprised physical tests which involved the monitoring of expansion in the test specimens. The third stage involved chemical analysis …

Bevacizumab Effect on Topotecan Pharmacokinetics in a Murine Orthotopic Rhabdomyosarcoma Xenograft Model
… rhabdomyosarcoma xenograft model. However, the effects of BEV on the pharmacokinetics of TPT and the antitumor activity of TPT have not been evaluated. This study aimed to investigate the effect of BEV on TPT systemic and tumoral pharmacokinetics and to determine how these changes affect the …

The Effect of General Anaesthesia on Circadian Rhythms in Mice
… may be, at least in part, responsible for these effects, causing timedependent shifts on circadian rhythms of behaviour, physiology, and cognitive parameters. However, due to the lack of consistency in the study design between experiments, the specific effect of GA on circadian rhythms in …

Optimising Cardiovascular Disease Risk Assessment: Application of Dynamic Prediction Tools and Risk Stratification Strategies Using Electronic Health Records
… who are at higher risk of CVD is fundamental for effectively implementing prevention strategies with limited health care resources and subsequently reducing the burden of CVD. For this purpose, numerous prognostic cardiovascular risk prediction models have been developed in populations from …

The Isotonic Regression Framework
… or categorical predictor variables results as an effect of the dose-response relationship. Isotonic regression is an alternative proposal when one wishes to establish a dose-response relationship, categorize continuous variables and estimate threshold values. The only assumption for this approach …
