Fractal Rigidity in Migraine [PDF]

open access: yes, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...

Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

open access: yesMolecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...

Strategic Network Interdiction [PDF]

open access: yes
We develop a strategic model of network interdiction in a non-cooperative game of flow. An adversary, endowed with a bounded quantity of bads, chooses a flow specifying a plan for carrying bads through a network from a base to a target.

Computer program determines gas flow rates in piping systems [PDF]

open access: yes, 1966
Computer program calculates the steady state flow characteristics of an ideal compressible gas in a complex piping system. The program calculates the stagnation and total temperature, static and total pressure, loss factor, and forces on each element in ...

Screening for lung cancer: A systematic review of overdiagnosis and its implications

open access: yesMolecular Oncology, EarlyView.
Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Numerical analysis of energy loss characteristics of guide vane centrifugal pump as turbine

open access: yesFrontiers in Energy Research
The structure of the guide vane centrifugal pump as turbine is complex, and the internal flow characteristics directly affect the energy loss distribution.

Numerical Simulation and Experiment on Flow Field in Horizontal Tubing-Casing Annulus with a Tubing Coupling

open access: yesShiyou jixie, 2023
Accurate prediction of annulus pressure loss is vital for drilling and completion of deep and ultra-deep wells.Research on flow field in annulus is theoretically fundamental to prediction of annulus pressure loss.To reveal the flow field of the ...

Shortest path and maximum flow problems in planar flow networks with additive gains and losses [PDF]

open access: yes, 2016
In contrast to traditional flow networks, in additive flow networks, to every edge e is assigned a gain factor g(e) which represents the loss or gain of the flow while using edge e.

Counselling for people with sight loss in the UK: The need for provision and the need for evidence [PDF]

open access: yes, 2010
For adults of any age the diagnosis of a visual impairment can be traumatic, and timely referral to informal peer support and/or professional counselling may be both beneficial and appropriate.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.
