Ultrahigh-density spin-polarized hydrogen isotopes from the photodissociation of hydrogen halides: new applications for laser-ion acceleration, magnetometry, and polarized nuclear fusion

open access: yesLight: Science & Applications, 2021
Spin-polarized hydrogen: production by photodissociation A laser-based scheme to produce spin-polarized hydrogen (SPH) at much higher densities than conventional methods could create new opportunities in physics.

Presynaptic partner selection during retinal circuit reassembly varies with timing of neuronal regeneration in vivo

open access: yesNature Communications, 2016
Neurons in the zebrafish retina regenerate. Here, Yoshimatsu and colleagues show that retinal horizontal cells maintain their synaptic preferences for a limited period before circuit remodeling is triggered after photoreceptor loss.

Structures and Structural Realism [PDF]

open access: yesLogic Journal of the IGPL, 2005
Summary: The `ontic' form of structural realism (OSR), roughly speaking, admits a complete elimination of the objects in the discourse of scientific theories, leaving us with structures only. As put by the defenders of such a claim, the idea is that all there is are structures and, if the relevant structures are to be set-theoretical constructs ...

Crosstalk between PI3K/Akt and Wnt/β-catenin pathways promote colorectal cancer progression regardless of mutational status

open access: yesCancer Biology & Therapy, 2022
The PI3K/Akt and Wnt/β-catenin pathways play an important role in the acquisition of the malignant phenotype in cancer. However, there are few data regarding the role of the interplay between both pathways in colorectal cancer (CRC) progression.

Carbon dioxide capture and conversion by an acid-base resistant metal-organic framework

open access: yesNature Communications, 2017
Increasing CO2 emissions pose serious environmental issues. Here, the authors report the synthesis of a robust metal-organic framework which displays high volumetric uptake of post-combustion CO2 under ambient conditions and can catalyze CO2 fixation ...

Numerical Investigation on the Transmission Loss of Skin Panels Based on the Intelligent PSO-CGA Algorithm

open access: yesIEEE Access, 2018
In the reported research, they only analyzed the impacts of restraint damping parameters on acoustic characteristics of skin panels, but failed to adopt advanced optimization algorithms to conduct an optimization design on restraint damping effects.

Feasibility study on pre or postoperative accelerated radiotherapy (POP-ART) in breast cancer patients

open access: yesPilot and Feasibility Studies, 2020
Background In early-stage breast cancer, the cornerstone of treatment is surgery. After breast-conserving surgery, adjuvant radiotherapy has shown to improve locoregional control and overall survival rates.

Computational Structuralism†

open access: yesPhilosophia Mathematica, 2005
The authors desire to characterize the natural numbers by their structure, as opposed to designating a particular choice of objects like \(\emptyset\), \(\{\emptyset\}\), etc. But at the same time, they wish to rule out nonstandard models -- and not to make their description circular.
