Construction of pursuit strategies with using Lyapunov functions

open access: yes, 2018
This paper is concerned with differential pursuit-evasion games, in which several agents chase one. The time of capture of a target is used as the criterion. The motion of agents is simple one, the velocities are piecewise-continuous.

Tax Evasion in the Philippines, 1981-1985 [PDF]

open access: yes
From the administrative and policy perspective, determination of magnitude of tax evasion and an analysis of tax evasion levels are imperative so that authorities may evaluate the success or failure of the enforcement mechanism.

SCPL-TD3: An Intelligent Evasion Strategy for High-Speed UAVs in Coordinated Pursuit-Evasion

open access: yesDrones
The rapid advancement of kinetic pursuit technologies has significantly increased the difficulty of evasion for high-speed UAVs (HSUAVs), particularly in scenarios where two collaboratively operating pursuers approach from the same direction with ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Research on Pursuit-evasion Games with Multiple Heterogeneous Pursuers and A High Speed Evader

open access: yes, 2015
We deal with Pursuit-evasion games with a high speed evader which has superiority in velocity over a group of heterogeneous pursuers in this paper. Heterogeneity in the group of pursuers is expressed as heterogeneity in the individual maximum speeds.

Heuristics for the Multi-Robot Worst-Case Pursuit-Evasion Problem

open access: yesIEEE Access, 2017
There is a growing demand for the use of robots to assist humans in their tasks, especially those involving risks, such as search and rescue. For this reason, coordination among several robots has been a common option, and one of the ways to study and ...

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

open access: yesMolecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Timing Tax Evasion [PDF]

open access: yes
Standard models of tax evasion implicitly assume that evasion is either fully detected, or not detected at all. Empirically, this is not the case, casting into doubt the traditional rationales for interior evasion choices.
