Navigating permanent underdetermination in dark energy and inflationary cosmology [PDF]

arXiv
We identify troubling cases of so-called `permanent underdetermination' in both dark energy and inflationary cosmology. We bring to bear (a) a taxonomy of possible responses to underdetermination, and (b) an understanding of both dark energy and inflationary cosmology from an effective field point of view. We argue that, under certain conditions, there

Broadband Acoustic Purcell Effect from Collective Bound States in the Continuum

Advanced Science, EarlyView.
This study introduces a novel six‐cavity system that utilizes collective quasibound states in the continuum (QBICs) to achieve a broadband acoustic Purcell effect. By strongly coupling five QBICs with an acoustic source within the introduced system, the research demonstrates a significant enhancement in sound emission from 625 to 900 Hz, paving the way

DNA–Protein Binding is Dominated by Short Anchoring Elements

Advanced Science, EarlyView.
This study delineate the binding mechanism of transcription factors (TFs) in the genome with the knowledge obtained at thermodynamic equilibrium conditions. Through KaScape experiments, combined with the AEEscape algorithm development, they identified the minimal dominant interacting elements, termed as Anchoring Elements (AEs).

A Hollow Shell‐Lattice Soft Robot in Flexible Pipelines with Flowing Fluids

Advanced Science, EarlyView.
This study proposes a novel shell‐lattice robot with hollow bodies, capable of crawling through pipes with flowing fluids of high velocities and viscosities and mixed with impurities. The robot also features capabilities of crawling with high payloads, in curved pipes, and unthethered crawling. These unique properties make this robot high promising for

Multi‐Shank 1024 Channels Active SiNAPS Probe for Large Multi‐Regional Topographical Electrophysiological Mapping of Neural Dynamics

Advanced Science, EarlyView.
This research article introduces a novel CMOS neural probe with 1024 channels distributed across eight shanks. The SiNAPS probe allows for the simultaneous recording of both local field potentials and action potentials in large brain areas. The probe's design allows for detailed mapping and linking neural dynamics and population unit activity, as ...

Bioinspired Mechanisms and Actuation of Soft Robotic Crawlers

Advanced Science, EarlyView.
Researchers have been developing soft materials and robotic crawlers inspired by soft‐bodied animals to mimic effective crawling in complex environments. This review explores the state‐of‐the‐art in soft crawlers, highlighting the interaction between materials, crawling mechanisms, actuation, and applications. The review concludes by providing insights

Longitudinal, Multimodal Tracking Reveals Lasting Neurovascular Impact of Individual Microinfarcts

Advanced Science, EarlyView.
Jin et al. investigate the neurovascular impact of microinfarcts, revealing transient neural suppression with minimal cell death and recovery linked to vascular remodeling. Fast‐spiking interneurons exhibit reduced excitability, whereas regular‐spiking neurons showed increased bursting activity. Disruptions in low‐gamma phase locking suggest persistent
