Case report: Long-term survival in a patient with metastatic colorectal cancer treated with trifluridine/tipiracil in the third-line setting

Frontiers in Oncology, 2023
Third-line treatment with trifluridine/tipiracil (FTD/TPI) is recommended for patients with metastatic colorectal cancer (mCRC) or gastric/gastroesophageal cancer (GC) who have progressed beyond first- and second-line therapy.

Three-Dimensional Path Following Control for Underactuated AUV Based on Ocean Current Observer

Drones
In the marine environment, the motion characteristics of Autonomous Underwater Vehicles (AUVs) are influenced by unknown factors such as time-varying ocean currents, thereby amplifying the complexity involved in the design of path-following controllers ...

Line Following Roboat

International Journal of Advanced Research in Science, Communication and Technology
This project presents a line following robot that uses sensors and microcontrollers to navigate along a predetermined path. The robot is designed to follow a line or path marked on the floor, using infrared sensors to detect the line and adjust its trajectory accordingly.

Dynamical Sieve of Eratosthenes

, 2011
In this document, prime numbers are related as functions over time, mimicking the Sieve of Eratosthenes. For this purpose, the mathematical representation is a uni-dimentional time line depicting the number line for positive natural numbers N, where each

Theory of the vortex matter transformations in high Tc superconductor YBCO

, 2003
Flux line lattice in type II superconductors undergoes a transition into a "disordered" phase like vortex liquid or vortex glass, due to thermal fluctuations and random quenched disorder.

Three-Dimensional Path Following Control of Underactuated AUV Based on Nonlinear Disturbance Observer and Adaptive Line-of-Sight Guidance

IEEE Access
In this study, a backstepping sliding mode control method (NDO-ABSC) based on nonlinear disturbance observer (NDO) and adaptive line-of-sight guidance (ALOS) is proposed to address the three-dimensional path following control problem of underactuated ...

Wolf-Rayet nebulae as tracers of stellar ionizing fluxes: I. M1-67 [PDF]

, 1999
We use WR124 (WN8h) and its associated nebula M1-67, to test theoretical non-LTE models for Wolf-Rayet (WR) stars. Lyman continuum ionizing flux distributions derived from a stellar analysis of WR124, are compared with nebular properties via photo ...

Segre forms and Kobayashi-L\"ubke inequality [PDF]

, 2016
Starting from the description of Segre forms as direct images of (powers of) the first Chern form of the (anti)tautological line bundle on the projectivized bundle of a holomorphic hermitian vector bundle, we derive a version of the pointwise Kobayashi-L\
