Ionic Liquid‐Enhanced 3D Printed Flexible Resin for Pressure‐Sensing Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A 3D‐printed resin–ionic liquid (IL) composite forms gyroid ionotronic architectures showing dynamic ionic migration under compression. Impedance analysis reveals distinct frequency responses across three topologies at high IL concentrations.

Warm dark matter primordial spectra and the onset of structure formation at redshift z

open access: yes, 2013
Analytic formulas reproducing the warm dark matter (WDM) primordial spectra are obtained for WDM particles decoupling in and out of thermal equilibrium which provide the initial data for WDM non-linear structure formation.

Intergalactic Helium Absorption in Cold Dark Matter Models [PDF]

open access: yes, 1996
Observations from the HUT and the HST have recently detected HeII absorption along the lines of sight to two high redshift quasars. We use cosmological simulations with gas dynamics to investigate HeII absorption in the cold dark matter (CDM) theory of ...

Bioprinting of Microtissues Within Mechanically Tunable Support Baths to Engineer Anisotropic Musculoskeletal Tissues

open access: yesAdvanced Science, EarlyView.
This study presents a novel 4D bioprinting platform for engineering biomimetic musculoskeletal grafts. By tuning the mechanical properties of support baths, we enhance tissue fusion, collagen alignment, and cell differentiation. Using this strategy, we successfully fabricate scaled‐up, anisotropic tissues such as meniscus, articular cartilage, and ...

Application of PRECEDE-PROCEED Planning Model in Transforming the Clinical Decision Making Behavior of Physical Therapists in Myanmar

open access: yesFrontiers in Public Health, 2019
Introduction: Physical therapists in Myanmar use a prescriptive model of Clinical Decision Making (CDM). Improving CDM effectiveness is one essential factor in professionalizing practice and enhancing patient outcomes.

An Isocurvature CDM Cosmogony. I. A Worked Example of Evolution Through Inflation

open access: yes, 1998
I present a specific worked example of evolution through inflation to the initial conditions for an isocurvature CDM model for structure formation. The model invokes three scalar fields, one that drives power law inflation, one that survives to become ...

Cosmological Perturbation Theory in the Synchronous vs. Conformal Newtonian Gauge [PDF]

open access: yes, 1994
We present a systematic treatment of the linear theory of scalar gravitational perturbations in the synchronous gauge and the conformal Newtonian (or longitudinal) gauge. We first derive the transformation law relating the two gauges.

The Mitochondrial Guardian α‐Amyrin Mitigates Alzheimer's Disease Pathology via Modulation of the DLK‐SARM1‐ULK1 Axis

open access: yesAdvanced Science, EarlyView.
Dietary habits play a key role in chronic diseases, and higher annual consumption of fruit and vegetable may lower risk of dementia. Artificial intelligence predicts the lipid‐like compound α‐Amyrin (αA) from plants with edible peels as a drug candidate against Alzheimer's disease.

Large-Scale Mass Power Spectrum from Peculiar Velocities [PDF]

open access: yes, 1998
This is a brief progress report on a long-term collaborative project to measure the power spectrum (PS) of mass density fluctuations from the Mark III and the SFI catalogs of peculiar velocities.

Differentiating CDM and Baryon Isocurvature Models with 21 cm Fluctuations

open access: yes, 2011
We discuss how one can discriminate models with cold dark matter (CDM) and baryon isocurvature fluctuations. Although current observations such as cosmic microwave background (CMB) can severely constrain the fraction of such isocurvature modes in the ...
