Quantum state cloning using Deutschian closed timelike curves [PDF]

open access: yes, 2013
We show that it is possible to clone quantum states to arbitrary accuracy in the presence of a Deutschian closed timelike curve (D-CTC), with a fidelity converging to one in the limit as the dimension of the CTC system becomes large---thus resolving an ...

EMT in breast cancer metastasis: an interplay of microRNAs, signaling pathways and circulating tumor cells

open access: yesFrontiers in Bioscience-Landmark, 2020
Epithelial to Mesenchymal Transition (EMT) is a biological process characterized by the transition from immotile epithelial cells to motile mesenchymal cells.

Closed timelike curves in general relativity [PDF]

open access: yes, 2002
Many solutions of Einstein's field equations contain closed timelike curves (CTC). Some of these solutions refer to ordinary materials in situations which might occur in the laboratory, or in astrophysics.

Entry effects of droplet in a micro confinement: implications for deformation-based CTC microfiltration

open access: yes, 2015
Deformation based circulating tumor cell (CTC) microchips are a representative diagnostic device for early cancer detection. This type of device usually involves a process of CTC trapping in a confined microgeometry. Further understanding of the CTC flow

Superluminal Propagation and Acausality of Nonlinear Massive Gravity [PDF]

open access: yes, 2013
Massive gravity is an old idea: trading geometry for mass. Much effort has been expended on establishing a healthy model, culminating in the current ghost-free version.

Applications of RNA characterisation in circulating tumour cells

open access: yesFrontiers in Bioscience-Landmark, 2020
Circulating tumour cells (CTCs) are shed into the bloodstream from both primary and secondary tumours and provide a non-invasive means to study tumor progression and response to treatment.

Cost-effectiveness analysis of 3-D computerized tomography colonography versus optical colonoscopy for imaging symptomatic gastroenterology patients.

open access: yes, 2013
BACKGROUND: When symptomatic gastroenterology patients have an indication for colonic imaging, clinicians have a choice between optical colonoscopy (OC) and computerized tomography colonography with three-dimensional reconstruction (3-D CTC).
