Gold‐Enhanced Brachytherapy by a Nanoparticle‐Releasing Hydrogel and 3D‐Printed Subcutaneous Radioactive Implant Approach (Adv. Healthcare Mater. 23/2023)

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.

conceptual metaphor and the acquisition of english metaphorical competence by persian english majors: a cognitive linguistic approach

بنا براستدلال زبانشناسان شناختی ، اندیشه آدمی تا حدّ زیادی استعاری است: ما اندیشه ای را، و یا قلمرو مفهومی معیّنی را، بر حسب اندیشه و یا قلمرو مفهومی معیّن دیگری درک ویا تجربه می کنیم. موارد این نوع اندیشیدن ، که استعارات مفهومی خوانده می شوند، در زبان های گوناگون به صورت تعبیرات استعاری واقعیّت می یابند. به گمان بعضی از پزوهشگران زبان دوم، آموزش وفراگیری این گونه تعبیرات باید بخشی لازم از برنامه ه...

A study on dosimetry accuracy of Strut-Adjust Volume Implant (SAVI) brachytherapy

Introduction: Accelerated Partial Breast Irradiation (APBI) is an effective treatment for breast carcinomas because of its limited number of fractions. Strut-adjusted volume implant (SAVI) is a HDR brachytherapy applicator to deliver the prescription dose with good PTV coverage and acceptable dose to skin, chest wall and organ at risks. Acceptable clinical outcomes depend on a...

Quantifying Stranded Implant Displacement Following Prostate Brachytherapy

We aim to compute radioactive stranded-implant displacement during and after prostate brachytherapy. We present the methods used to identify corresponding seeds in planned, intra-operative and postimplant patient data that enable us to compute seed displacements. A minimum cost network flow algorithm is used, on 8 patients, for needle track detection to group seeds into needles that can be matc...
