Material Viscoelasticity-Induced Drift of Micro-Accelerometers.
Zhou W, Peng P, Yu H, Peng B, He X. Zhou W, et al. Materials (Basel). 2017 Sep 14;10(9):1077. doi: 10.3390/ma10091077. Materials (Basel). 2017. PMID: 28906447 Free PMC article.
The accelerometers stored at room temperature displayed a continuous drift of zero offset and sensitivity because of the material viscoelasticity. Moreover, the drift level of accelerometers experiencing high temperature load was relatively higher than …

Analysis on the inherent noise tolerance of feedforward network and one noise-resilient structure.
Lu W, Zhang Z, Qin F, Zhang W, Lu Y, Liu Y, Zheng Y. Lu W, et al. Neural Netw. 2023 Aug;165:786-798. doi: 10.1016/j.neunet.2023.06.011. Epub 2023 Jun 17. Neural Netw. 2023. PMID: 37418861
However, when we realize a neural network in analog circuits, the circuit-based model is sensitive to hardware nonidealities. The nonidealities, such as random offset voltage drifts and thermal noise, may lead to variation in hidden neurons and further affect neural …

High-Precision Low-Temperature Drift LDO Regulator Tailored for Time-Domain Temperature Sensors.
Răducan C, Neag M, Grăjdeanu A, Țopa M, Negoiță A. Răducan C, et al. Sensors (Basel). 2022 Feb 16;22(4):1518. doi: 10.3390/s22041518. Sensors (Basel). 2022. PMID: 35214420 Free PMC article.
Simulation and measurement results are presented for implementation in a standard 130 nm CMOS process: the LDO outputs a stable 1 V voltage, when the input voltage varies between 1.25 V to 1.5 V, the load current between 0 and 100 mA, and the load capacitor between zero an …

Spatio-temporal vernier acuity.
Gorea A, Hammett ST. Gorea A, et al. Spat Vis. 1998;11(3):295-313. doi: 10.1163/156856898x00040. Spat Vis. 1998. PMID: 9584346
The transposition of a SSV task into a STV one yields the following experimental format: an object (in the present case a Gaussian Blob) drifts with a constant velocity, V, disappears at x0, t0 and reappears after a variable duration delta t at a position x1 +/- delta x wi …

Sub-millinewton thrust stand and wireless power coupler for microwave-powered small satellite thrusters.
Wachs BN, Jorns BA. Wachs BN, et al. Rev Sci Instrum. 2022 Aug 1;93(8):083507. doi: 10.1063/5.0088831. Rev Sci Instrum. 2022. PMID: 36050119
Thrust is measured in a displacement mode using the change in position of the pendulum arm as measured by an optical displacement sensor. Passive eddy-current damping is used to offset oscillations and decrease setting time. An in situ calibration rig using known masses is …

Comparison of methods for spectral alignment and signal modelling of GABA-edited MR spectroscopy data.
Rideaux R, Mikkelsen M, Edden RAE. Rideaux R, et al. Neuroimage. 2021 May 15;232:117900. doi: 10.1016/j.neuroimage.2021.117900. Epub 2021 Feb 27. Neuroimage. 2021. PMID: 33652146 Free PMC article.
Here we use the proportion of grey matter within the MRS voxel as a proxy for ground-truth GABA concentration to compare the performance of four spectral alignment methods (i.e., retrospective frequency and phase drift correction) and six GABA signal modelling methods. We …

Bayesian Age-Period-Cohort Prediction of Mortality of Type 2 Diabetic Kidney Disease in China: A Modeling Study.
Wu X, Du J, Li L, Cao W, Sun S. Wu X, et al. Front Endocrinol (Lausanne). 2021 Oct 29;12:767263. doi: 10.3389/fendo.2021.767263. eCollection 2021. Front Endocrinol (Lausanne). 2021. PMID: 34777260 Free PMC article.
The age-specific annual percentage changes (local drifts) were below zero in all age groups from 1990 to 2019 except for males aged above 65 to 69 years, and for females aged above 70 to 74 years. ...Despite a decrease in age-specific DKD death rates, the reduction …

Upper Limb Position Tracking with a Single Inertial Sensor Using Dead Reckoning Method with Drift Correction Techniques.
Bai L, Pepper MG, Wang Z, Mulvenna MD, Bond RR, Finlay D, Zheng H. Bai L, et al. Sensors (Basel). 2022 Dec 29;23(1):360. doi: 10.3390/s23010360. Sensors (Basel). 2022. PMID: 36616958 Free PMC article.
However, significant errors are generated after applying the dead reckoning method because of the presence of sensor offsets and drift. These errors limit the feasibility of monitoring upper limb motion via a single inertial sensing system. ...The results show that …

Optical surface guidance for submillimeter monitoring of patient position during frameless stereotactic radiotherapy.
Covington EL, Fiveash JB, Wu X, Brezovich I, Willey CD, Riley K, Popple RA. Covington EL, et al. J Appl Clin Med Phys. 2019 Jun;20(6):91-98. doi: 10.1002/acm2.12611. Epub 2019 May 16. J Appl Clin Med Phys. 2019. PMID: 31095866 Free PMC article.
Prior to ACO, the offset magnitude for non-zero table positions had a median of 0.79 mm and was found to increase with increasing distance from isocenter to the anterior patient surface. After ACO, the median magnitude was 0.74 mm, but the dependence on surface-to-i …

An experimental method to directly measure DQE[Formula: see text] at k  =  0 for 2D x-ray imaging systems.
Ji X, Feng M, Zhang R, Chen GH, Li K. Ji X, et al. Phys Med Biol. 2019 Apr 4;64(7):075013-75013. doi: 10.1088/1361-6560/ab10a2. Phys Med Biol. 2019. PMID: 30884472 Free PMC article.
As a result, some experimental methods may yield a nonphysical NPS value at k = 0, which makes the measured DQE(k)| (k=0) deviate from the true zero-frequency DQE. This work presents new results from three aspects: 1) system drift is a significant error source when …
