ON THE TIME VALUE OF RUIN IN THE DISCRETE TIME RISK MODEL [PDF]

Using an approach similar to that of Gerber and Shiu (1998), a recursive formula is given for the expected discounted penalty due at ruin, in the discrete time risk model. With it the joint distribution of three random variables is obtained; time to ruin,

Single‐Cell Analysis Reveals that Vitamin C Inhibits Bone Metastasis of Renal Cancer via Cell Cycle Arrest and Microenvironment Remodeling

Advanced Science, EarlyView.
3D‐cultured renal cancer cells exhibit stem‐like phenotypes and are more efficient in generating bone metastases. Vitamin C treatment can suppress the development of bone metastasis. Single‐cell transcriptomic analysis reveals that vitamin C inhibits metastasis by inducing tumor cell cycle arrest, suppressing osteoclast differentiation, and reducing ...

Nanogenerator Neuromodulation to Enable Locomotion Rehabilitation for Spinal Cord Injury via Epidural Electrical Stimulation

Advanced Science, EarlyView.
A hybrid nanogenerator (H‐NG) has been developed to be applied in epidural electrical stimulation (EES). Compared with a commercial stimulus generator (SG), the H‐NG can elicit hindlimb locomotion in rats with much lower electrical parameters and much smaller individual differences.

Abiotic Factors and Plant Communities Shape the Distribution of Soil Pathogenic Oomycetes in Chinese Grasslands

Advanced Science, EarlyView.
The continental‐scale study reveals that soil phosphorus strongly predicts the richness of soil pathogenic oomycetes in Chinese grasslands, while precipitation and plant species richness drive their absolute abundance; modeling predicts ≈42% of grassland areas may face elevated oomycete disease risk under future climate scenarios, especially in typical

OPTIMAL POLICIES FOR DISCRETE TIME RISK PROCESSES WITH A MARKOV CHAIN INVESTMENT MODEL [PDF]

We consider a discrete risk process modelled by a Markov Decision Process. The surplus could be invested in stock market assets. We adopt a realistic point of view and we let the investment return process to be statistically dependent over time.

Identification and Drug Screening of Single Cells from Human Tumors on Semiconductor Chip for Cancer Precision Medicine

Advanced Science, EarlyView.
The study innovatively integrates single‐cell electric impedance identification and drug screening on a semiconductor chip, addressing tumor heterogeneity limitations. The system achieves label‐free cancer cell recognition while concurrently evaluating drug efficacy on cancer cells and toxicity on noncancerous cells.

Approximating the Finite-Time Ruin Probability under Interest Force [PDF]

We present an algorithm to determine both a lower and an upper bound for the finite-time probability of ruin for a risk process with constant interest force. We split the time horizon into smaller intervals of equal length and consider the probability of

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.
