The Imprint of Gravitational Waves on the Cosmic Microwave Background [PDF]

open access: yes, 1993
Long-wavelength gravitational waves can induce significant temperature anisotropy in the cosmic microwave background. Distinguishing this from anisotropy induced by energy density fluctuations is critical for testing inflationary cosmology and theories ...

Swelling‐Programmed Topographical Guidance for Dynamic Spheroid Self‐Assembly via a Mechanochemical Hydrogel Niche

open access: yesAdvanced Functional Materials, EarlyView.
A swelling‐programmed micropatterned hydrogel guides adherent cells through a controlled transition from cell–matrix anchoring to cadherin‐mediated cell–cell compaction, enabling rapid assembly of high‐viability spheroids with defined size and morphology.

Comparison of bone marrow aspirate cytology, touch imprint cytology and trephine biopsy for bone marrow evaluation

open access: yesHematology Reports, 2011
Studies have compared the role of bone marrow aspirate cytology and trephine biopsy for diagnosing various hematological disorders but fewer studies have compared the relative value of imprint cytology with aspirate and trephine biopsy. The present study

Multi‐Scale Interface Engineering of MXenes for Multifunctional Sensory Systems

open access: yesAdvanced Functional Materials, EarlyView.
MXenes, as two‐dimensional transition metal carbides and nitrides, demonstrate remarkable capabilities for multifunctional sensing applications. This review systematically examines multi‐scale interface engineering approaches that enhance sensing performance, enable diverse detection functionalities, and improve system‐level compatibility in MXene ...

The Imprint of Cosmic Reionization on Galaxy Clustering

open access: yes, 2007
We consider the effect of reionization on the clustering properties of galaxy samples at intermediate redshifts (z~0.3-5.5). Current models for the reionization of intergalactic hydrogen predict that overdense regions will be reionized early, thus ...

Dynamin recruitment by clathrin coats: a physical step? [PDF]

open access: yes, 2003
Recent structural findings have shown that dynamin, a cytosol protein playing a key-role in clathrin-mediated endocytosis, inserts partly within the lipid bilayer and tends to self-assemble around lipid tubules. Taking into account these observations, we

THE AFRICAN PROVERB AND THE LIVING PRESENT

open access: yesProverbium, 2012
Modernity, the triptych upon which a corpus of Igbo sayings has been created, arose pari passu with the larger incidence of post-colonialism. As a phenomenon with a pervasive grip on the life and imagination of the African, post-colonialism has had its ...

Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

open access: yesAdvanced Functional Materials, EarlyView.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

Diagnostic utility of imprint cytology of endoscopic gastric biopsy: A cyto-histo correlation study

open access: yesJournal of Pathology of Nepal, 2019
Background: Upper gastrointestinal endoscopy is a common procedure done for suspected cases of gastric malignancies. Histopathological examination of gastric tissue has been a gold standard for the diagnosis. Imprint smears of the gastric biopsy specimen

Chirality and Organization of Adsorbates Modify Surface Phonon Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Chirality and molecular organization are shown to influence surface phonon dynamics in gold films. Time‐resolved Joule heating measurements reveal that ordered homochiral monolayers increase the Debye temperature and disordered layers reduce it, while ordered racemic controls have no effect.
