General Ramified Recurrence is Sound for Polynomial Time

open access: yes, 2010
Leivant's ramified recurrence is one of the earliest examples of an implicit characterization of the polytime functions as a subalgebra of the primitive recursive functions.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Photoionization Modeling of the Low Luminosity Seyfert 1 Nucleus in NGC 3516

open access: yes, 2015
Spectroscopic observations of the low luminosity Seyfert 1 nucleus in NGC 3516 obtained with the Hubble Space Telescope show that the visible spectrum is dominated by the Balmer emission lines of Hydrogen (H) and a continuum luminosity that rises into ...

Artesunate Nanoplatform Targets the Serine–MAPK Axis in Cancer‐Associated Fibroblasts to Reverse Photothermal Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Materials, EarlyView.
The artesunate nanoplatform selectively targets ECM CAF, functioning as a GTPase inhibitor through disruption of intracellular serine homeostasis. This metabolic intervention effectively suppresses MAPK cascade activity, which consequently inhibits PTT‐induced CAF to ECM CAF differentiation.

Ionically Conductive Elastic Polymer Binder for Ultrahigh Loading Electrode in High‐Energy‐Density Lithium Batteries

open access: yesAdvanced Materials, EarlyView.
An ionically conductive elastic polymer (ICEP) binder is introduced for fabricating ultrahigh mass‐loading NCM811 cathodes, offering enhanced elasticity, adhesion, and ionic conductivity for improved structural and interfacial stability. The ICEP‐based ultrahigh loading cathode delivers 377.6 Wh kgcell−1/1016.8 Wh Lcell−1 (including packaging) when ...

Dynamical NNLO parton distributions

open access: yes, 2009
Utilizing recent DIS measurements (\sigma_r, F_{2,3,L}) and data on hadronic dilepton production we determine at NNLO (3-loop) of QCD the dynamical parton distributions of the nucleon generated radiatively from valencelike positive input distributions at

Biocompatible Porphyrin Derivatives Electron Beam and Extreme Ultraviolet Photoresists: High Resolution and High Etch Resistance

open access: yesAdvanced Materials Interfaces, EarlyView.
Porphyrin derivatives are introduced for electron beams and extreme ultraviolet lithography. The lithographic performance of the novel CuTP‐4Epoxy photoresist is excellent, with a resolution of 18 nm in EBL and 20 nm in EUVL, and the photoresist also exhibits high etch resistance.
