This article provides a practical overview of numerical solutions to the heat equation using the finite difference method. The forward time, centered space (FTCS), the backward time, centered space (BTCS), and Crank-Nicolson schemes are developed, and applied to a simple problem involving the one-dimensional heat equation. Complete, working Matlab codes for each scheme are presented. The result...
Biliary tract cancers (BTCs) are a heterogeneous group of neoplasms characterized by a dismal prognosis. At variance with most solid tumors, no effective molecular targeted agent has been currently approved for BTCs treatment and their molecular landscape has only been recently investigated. Comprehensive mutational profiling studies identified IDH1/2 and BAP1 as characteristic of intrahepatic ...
Anomalous transport cannot be adequately described with classical Fickian advectiondispersion equations (ADE) with constant coefficients. Rather, fractional calculus models may be used, which capture salient features of anomalous transport (e.g., skewness and power law tails). FracFit is a parameter estimation tool based on space-fractional and time-fractional models used by the hydrology commu...
Although biliary tract cancers (BTCs) are known to have an inflammatory component, a detailed characterisation of immune-related transcripts has never been performed. In these studies, nCounter PanCancer Immune Profiling Panel was used to assess the expression of 770 immune-related transcripts in the tumour tissues (TTs) and matched adjacent tissues (ATs) of resected BTCs. Cox regression analys...
Water-saturated column experiments were conducted to investigate the effect of input concentration (C₀) and sand grain size on the transport and retention of low concentrations (1, 0.01, and 0.005 mg L⁻¹) of functionalized ¹⁴C-labeled multi-walled carbon nanotubes (MWCNT) under repulsive electrostatic conditions that were unfavorable for attachment. The breakthrough curves (BTCs) for MWCNT typi...
Mg-Al layered double hydroxides (LDHs) were applied to soils for controlling phosphorus (P) loss. The subsequent slow-release of immobilized P in LDHs-soil system is crucial its bioavailability crops. Saturated column experiments conducted investigate the influence carbonate and flow interruption (FI) on release retention phosphate results compared those obtained under bicarbonate or continuous...
In this study, displacement experiments of isoproturon were conducted in disturbed and undisturbed columns of a silty clay loam soil under similar rainfall intensities. Solute transport occurred under saturated conditions in the undisturbed soil and under unsaturated conditions in the sieved soil because of a greater bulk density of the compacted undisturbed soil compared to the sieved soil. Th...
Background Extrahepatic cholangiocarcinoma (eCCA) is a rare and aggressive disease consisted of conventional eCCA intraductal papillary neoplasm the bile duct (IPNB). Intraepithelial spread (IES) cancer cells beyond invasive area often observed in IPNBs; however, prevalence IES remains to be examined eCCAs. Here, we evaluated clinicopathological features eCCAs according tumor location, with foc...
influence of soil organic matter (som) on the adsorption, desorption and transport of polycyclic aromatic hydrocarbons (pahs) has already been given full investigation in soils. in this paper, confocal laser scanning microscope (clsm) was used to elucidate aqueous leaching of pahs in different types of soil with soil columns, which enhanced understanding on transport of pahs appreciably. four ...
