Advances in the study of reversing tumor drug resistance by targeting cancer-associated fibroblasts with nanomaterials [PDF]
Frontiers in ImmunologyCancer-associated fibroblasts (CAFs) are key components of the tumor microenvironment (TME) which promote drug resistance by remodeling the extracellular matrix, generating an immunosuppressive microenvironment, and activating metabolic signaling ...

Nonsinusoidal current and current reversals in a gating ratchet [PDF]
Physical Review E, 2015 In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the particles move.

Current reversals and synchronization in coupled ratchets [PDF]
Physical Review E, 2010 Current reversal is an intriguing phenomenon that has been central to recent experimental and theoretical investigations of transport based on ratchet mechanism. By considering a system of two interacting ratchets, we demonstrate how the coupling can be used to control the reversals.

Reverse Causality in Global Current Accounts [PDF]
SSRN Electronic Journal, 2010 The paper discusses global imbalances under the aspect of an asymmetric world monetary system. It identifies the US and Germany as center countries with rising / high current account deficits (US) and surpluses (Germany). These are matched by current account surpluses of countries stabilizing their exchange rates against the dollar (dollar periphery ...

Reversing the medical humanities [PDF]
, 2023 The paper offers the concept of reversing the medical humanities. In agreement with the call from Kristeva et al. to recognise the bidirectionality of the medical humanities, I propose moving beyond debates of attitude and aptitude in the application and

Tokamak Equilibria with Reversed Current Density [PDF]
Physical Review Letters, 2003 Observations of nearly zero toroidal current in the central region of tokamaks (the "current hole") raises the question of the existence of toroidal equilibria with very low or reversed current in the core. The solutions of the Grad-Shafranov equilibrium equation with hollow toroidal current density profile including negative current density in the ...
