3D (Bio) Printing Combined Fiber Fabrication Methods for Tissue Engineering Applications: Possibilities and Limitations

open access: yesAdvanced Functional Materials, EarlyView.
Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

Regulation of a Mammalian Gene Bearing a CpG Island Promoter and a Distal Enhancer

open access: yesCell Reports, 2013
A quantitative nucleosome occupancy assay revealed rules for nucleosome disposition in yeast and showed how disposition affects regulation of the GAL genes. Here, we show how those findings apply to the control of Kit, a mammalian gene.

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

open access: yesAdvanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

open access: yesAdvanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Intrathecal baclofen therapy in patients with spastic paraplegia: retrospective evaluation of pretreatment drugs, test dosage, dose increments and final therapy

open access: yesBrain and Spine
Introduction: Intrathecal baclofen therapy (ITB) is an effective alternative for severe generalized spasticity after unsuccessful oral spasmolytic therapy. Research question: What degree of severity, type and duration of pretreatment indicated ITB?

Nonconsumptive effects of a range‐expanding predator on juvenile lobster (Homarus americanus) population dynamics

open access: yesEcosphere, 2019
Distribution shifts poleward are a widespread response to climate change and can result in altered community composition and interactions among species that previously were geographically isolated.

Investigations of the lower and middle atmosphere at the Arecibo Observatory and a description of the new VHF radar project [PDF]

open access: yes, 1986
The atmospheric science research at the Arecibo Observatory is performed by means of (active) radar methods and (passive) optical methods. The active methods utilize the 430 NHz radar, the S-band radar on 2380 MHz, and a recently constructed Very High ...

Discovery of 21cm absorption in a $z_{\rm abs} =2.289$ DLA towards TXS 0311+430: The first low spin temperature absorber at z > 1

open access: yes, 2007
We report the detection of HI 21 cm absorption from the $z=2.289$ damped Lyman-$\alpha$ system (DLA) towards TXS 0311+430, with the Green Bank Telescope.

Trifluoromethoxylated Electron Acceptor Enabling Ternary Organic Solar Cells with over 20% Power Conversion Efficiency

open access: yesAdvanced Functional Materials, EarlyView.
ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...

Intraspecific diversity at two trophic levels influences plant–herbivore interactions

open access: yesEcosphere, 2020
Diversity within species can have community‐level effects similar in magnitude to those of species diversity. Intraspecific diversity in producers and consumers has separately been shown to affect trophic interactions, yet we have little understanding of
