Numerical Solution for the Dividend Value Function of a Dual Risk Model With Investment

Journal of Mathematics
This paper proposes a dual risk model with liquid reserve and proportional investments, this model is more suitable for real life. We derive the integral differential equations for the expected total discounted dividends before ruin.

Comparison of Amplitude‐ and Amplitude‐Frequency‐Modulated Pulses for Outer Volume Suppression in Cardiac MRI: Application to Myocardial T2$$ {T}_2 $$ Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate single‐ and dual‐band pulse modules for suppressing extra‐cardiac signal in cardiac MRI, and test their applicability for time‐efficient imaging with reduced FOV in myocardial T2$$ {T}_2 $$ mapping at 3 T. Methods Outer Volume Suppression (OVS) was implemented using two regional saturation slabs, along the phase‐encoding ...

Image Encoding With Blipped Gradients in an Echo Train

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose An MRI scanner was designed and built to encode k$$ k $$‐space points in the spin echoes occurring between 180∘$$ 18{0}^{\circ } $$ pulses in an echo train by using blipped B0$$ {B}_0 $$ gradient pulses applied just prior to those spin echoes.

Reference‐Superimposed Reconstruction (RS‐Recon) for Arterial Spin Labeling

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Conventional arterial spin labeling (ASL) reconstruction suffers from sign‐flipping errors and/or noise bias under strong background suppression (BS), limiting SNR optimization. We propose reference‐superimposed reconstruction (RS‐recon) to enable ideal BS and robust signal recovery.

Deciphering diverse cell‐death patterns to predict the prognosis and potential therapy target of hepatocellular carcinoma patients

VIEW, EarlyView.
Abstract Ninety percent of all primary liver malignancies are hepatocellular carcinomas (HCC), making liver cancer the third most common cause of cancer‐associated mortality. Different patterns of programmed cell death (PCD) are crucial for the survival of tumors, and they might serve as a prognostic marker for HCC.

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Downregulation of KRTAP2‐3 Suppresses Proliferation and Tumor Formation of Oral Cancer Cells via Inactivation of KRAS Signals

Cancer Science, EarlyView.
KRTAP2‐3 drives OSCC progression by sustaining both mesenchymal and proliferative properties through KRAS signaling. Loss of KRTAP2‐3 induces MET, suppresses KRAS pathway activation, and markedly reduces tumor cell proiferation and tumor formation as illustarted in Figure.

YBX1 Promotes Malignant Progression of HNSCC via Stabilizing NSUN2‐m5C Modified ATF4 mRNA

Cancer Science, EarlyView.
The diagram depicts the core axis and the key finding: “Targeting YBX1/NSUN2 abrogates HNSCC progression”. Within left‐sided HNSCC cells, NSUN2 mediates m5C methylation on the CDS of ATF4 mRNA; YBX1 then specifically recognizes and binds this modified site, augmenting ATF4 mRNA stability, which ultimately promotes cancer cell proliferation, migration ...

Mixed Super‐Circles

Computer Graphics Forum, EarlyView.
Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...
