Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Implantable Ionic Memristors Based on Natural Polymer Heterojunctions

Advanced Functional Materials, EarlyView.
We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

Intensity-modulated radiation therapy

Current Problems in Cancer, 2004
For the non radiotherapist, the recent developments of conformal radiotherapy and Intensity Modulated Radiotherapy (IMRT) may represent merely an increase in mystification from a baseline already shrouded in the obscure dark arts of physics. However, the principles of these developments are simple and as the technologies become available, there are ...

Intensity-modulated radiation therapy

Computing in Science & Engineering, 2002
Radiation therapy is a tricky business. The goal is to deliver as much radiation as possible to a tumor while sparing nearby noncancerous tissue. A newer approach, called intensity-modulated radiation therapy (IMRT), relaxes the requirement for a uniform dose distribution, yet delivers the radiation more accurately to the cancerous region.

Intensity Modulation of Olfactory Acuity.

Behavioral Neuroscience, 2003
Acuity is fundamental to sensory systems, establishing the foundation for detectable differences in stimulus quality and consequently shaping animals' sensory capacities. In the olfactory system, which samples intrinsically high-dimensional chemical information, acuity for odor quality is measurable by means of ad hoc dimensions based on behaviorally ...

Intensity‐modulated radiation therapy

Journal of Surgical Oncology, 2008
AbstractIntensity‐modulated radiation therapy (IMRT) has found widespread use in the treatment of head and neck cancers. This technology allows for conformal dose distributions around a tumor target while a rapid dose fall‐off spares surrounding critical structures.

Intensity-modulated moiré topography

Applied Optics, 1999
Moiré topography has the advantage of requiring only a single image to obtain a three-dimensional measurement, but it cannot discern the fringe order. Because there is an ambiguity problem when calculating the depth range by use of fringe intensity or phase unwrapping, it is impossible to obtain an absolute phase and an absolute depth range.

Compensators for intensity-modulated beams

Medical Dosimetry, 2002
This study describes the importance of attenuator scatter in the construction of compensators. The attenuator used in this study was Lipowitz metal, commonly referred to as cerrobend. Linear attenuation coefficients of cerrobend were measured in air for different thickness of cerrobend sheets and different field sizes for a 6-MV photon beam.
