SCS: Superior‐Vena‐Cava Compressing Shape‐Memory‐Alloy‐Based Implantable Device for Heart Failure
Advanced Engineering Materials, EarlyView.An implantable superior–vena‐cava compression device, utilizing biocompatible shape‐memory‐alloy actuators, regulates blood flow and thereby achieves an 18.6% reduction in end‐diastolic left ventricular volume in a porcine model of ADHF. This potential long‐term solution minimizes thrombosis risk by avoiding direct blood contact, offering a significant

A more accurate analytic calculation of the spectrum of cosmological perturbations produced during inflation [PDF]
Phys.Lett.B302:171-175,1993, 1993 Formulae are derived for the spectra of scalar curvature perturbations and gravitational waves produced during inflation, special cases of which include power law inflation, natural inflation in the small angle approximation and inflation in the slow roll approximation.

Physical Review D, 1999 Inflationary solutions are constructed in a specific five-dimensional model with boundaries motivated by heterotic M-theory. We concentrate on the case where the vacuum energy is provided by potentials on those boundaries. It is pointed out that the presence of such potentials necessarily excites bulk Kaluza-Klein modes.

Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, EarlyView.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

Comments on SUSY inflation models on the brane
, 2009 In this paper we consider a class of inflation models on the brane where the dominant part of the inflaton scalar potential does not depend on the inflaton field value during inflation.

Wearable Haptic Feedback Interfaces for Augmenting Human Touch
Advanced Functional Materials, EarlyView.The wearable haptic feedback interfaces enhance user experience in gaming, social media, biomedical instrumentation, and robotics by generating tactile sensations. This review discusses and categorizes current haptic feedback interfaces into force, thermal, and electrotactile stimulation‐based haptic feedback interfaces, elucidating their current ...

Inflation hardship, gender, and mental health
SSM: Population Health, 2023 Inflation hit a 40 year high in the United States in 2022, yet the impact of inflation related hardships on distress is poorly understood, particularly the impact on women, whose income is already more limited.

Inflection point inflation and reheating [PDF]
, 2016 We revisit the inflection point inflation with an extended discussion to large field values and consider the reheating effects on the inflationary predictions. Parametrizing the reheating dynamics in terms of the reheating temperature and the equation of state during inflation, we show how the observationally favored parameter space of inflection point

Extending the Range of Robust PCE Inflation Measures [PDF]
arXiv, 2022 Robust inflation measures gauge inflation behavior by excluding volatile expenditure categories from headline inflation. We evaluate the forecasting performance of a wide set of such measures between 1970 and 2024, including core, median, and trimmed mean personal-consumption-expenditure (PCE) inflation. Core inflation performs significantly worse than

Retrofitting Models of Inflation [PDF]
Nucl.Phys.B821:170-180,2009, 2009 I use the method of retrofitting, developed by Dine, Feng and Silverstein, to generate the scale of inflation dynamically, allowing it to be naturally small. This is a general procedure that may be performed on existing models of supersymmetric inflation.
