BOLD delay times using group delay in sickle cell disease [PDF]

open access: yesSPIE Proceedings, 2016
Sickle cell disease (SCD) is an inherited blood disorder that effects red blood cells, which can lead to vasoocclusion, ischemia and infarct. This disease often results in neurological damage and strokes, leading to morbidity and mortality. Functional Magnetic Resonance Imaging (fMRI) is a non-invasive technique for measuring and mapping the brain ...

Logistic proliferation of cells in scratch assays is delayed [PDF]

open access: yesBulletin of Mathematical Biology, 2016
Abstract Scratch assays are used to study how a population of cells recolonises a vacant region on a two-dimensional substrate after a cell monolayer is scratched. These experiments are used in many applications including drug design for the treatment of cancer and chronic wounds.

Delay estimation for CMOS functional cells [PDF]

open access: yesProceedings of the European Conference on Design Automation., 2002
Presents a new RC tree network model for delay estimation of CMOS functional cells. The model is able to reflect topological changes within a cell, which is of particular interest when doing performance driven layout synthesis. Further, a set of algorithms to perform worst case analysis on arbitrary CMOS functional cells using the proposed delay model,

LYMPHOID CELLS IN DELAYED HYPERSENSITIVITY [PDF]

open access: yesThe Journal of Experimental Medicine, 1972
X-irradiation up to 480 R does not inhibit either adoptive transfer of delayed hypersensitivity or production in vitro of soluble mediators, such as migration-inhibitory factor (MIF). Above that dosage and as high as 3000 R, adoptive transfer is inhibited, but production of MIF is not. An increase in skin response occurred when 24–48 hr were allowed to

In-service monitoring techniques for cell transfer delay and cell delay variation in ATM networks [PDF]

open access: yes, 1995
Cell transfer delay (CTD) and Cell delay variation (CDV) are ATM performance parameters. Monitoring CTD and CDV requires procedures for in-service measurement or estimation and for gaining the delay distribution statistics. This paper discusses the origin and definition of CTD and CDV, the latter being defined in terms of 2-point CDV and l-point CDV ...

A PVT resilient true‐time delay cell

open access: yesIET Circuits, Devices & Systems, 2023
Abstract A true‐time delay (TTD) cell in TSMC 0.18 μm CMOS technology for 1–5 GHz applications is presented. Process variations, ageing effects, field variations, and other non‐idealities have some impacts on the TTD cell's devices. One of the vulnerable specifications of TTD cells is their delay variation.

A Delayed Fatal Metastatic Hürthle Cell Carcinoma [PDF]

open access: yesActa Medica (Hradec Kralove, Czech Republic), 2011
Hürthle (oxyphilic or oncocytic) cell carcinoma is a variant of follicular cell carcinoma of thyroid. Although this entity of thyroid cancer is well known, its occurrence in young patients has scarcely been reported. We report a case of a 26 year-old male patient, at the time of diagnosis, of Turkish origin, who developed a tracheal, pulmonary and ...

Radiation-Induced Mitotic Delay in L Cells [PDF]

open access: yesRadiation Research, 1967
A study has been made of the dependence of the dose-response curve for mitotic delay on the age of the cells at the time of irradiation. The results obtained for randomly dividing cultures with ${\rm H}^{3}{\rm TdR}$ used to locate the position of the cells in the cell cycle at the time of irradiation indicated that mitotic delay increases from a ...
