Article
Self-organized growth of alloy superlattices
Patterning in nature typically occurs through self-organization, and interest has developed recently in the use of such spontaneous processes to fabricate periodically structured materials at the nanometre sca...

Article
Response of a strained semiconductor structure
The nanomechanical properties of thin silicon films will become increasingly critical in semiconductor devices, particularly in the context of substrates that consist of a silicon film on an insulating layer (...

Open AccessDynamic Mechanism for the Transcription Apparatus Orchestrating Reliable Responses to Activators
The transcription apparatus (TA) is a huge molecular machine. It detects the time-varying concentrations of transcriptional activators and initiates mRNA transcripts at appropriate rates. Based on the general ...

Spin-enhanced organic bulk heterojunction photovoltaic solar cells
Recently, much effort has been devoted to improve the efficiency of organic photovoltaic solar cells based on blends of donors and acceptors molecules in bulk heterojunction architecture. One of the major loss...

Arrays of giant octagonal and square cylinders by liquid crystalline self-assembly of X-shaped polyphilic molecules
Nanopatterning by molecular self-assembly has been a topic of intense research in pursuit of 'bottom-up' methods of generating structures for use in nanotechnology. The systems most widely studied have been tw...

Creation of helical Dirac fermions by interfacing two gapped systems of ordinary fermions
Topological insulators are a unique class of materials characterized by a Dirac cone state of helical Dirac fermions in the middle of a bulk gap. When the thickness of a three-dimensional topological insulator...

Central role of E3 ubiquitin ligase MG53 in insulin resistance and metabolic disorders
MG53 acts as an E3 ligase that targets the insulin receptor and IRS1 for ubiquitin-dependent degradation; when MG53 is upregulated, metabolic syndrome ensues.

Organic topological insulators in organometallic lattices
Topological insulators are a recently discovered class of materials having insulating bulk electronic states but conducting boundary states distinguished by nontrivial topology. So far, several generations of ...

Open AccessPhotostimulated near-infrared persistent luminescence as a new optical read-out from Cr3+-doped LiGa5O8
In conventional photostimulable storage phosphors, the optical information written by x-ray or ultraviolet irradiation is usually read out as a visible photostimulated luminescence (PSL) signal under the stimu...

Open AccessGenetic control of inflorescence architecture during rice domestication
Inflorescence architecture is a key agronomical factor determining grain yield, and thus has been a major target of cereal crop domestication. Transition from a spread panicle typical of ancestral wild rice (Oryz...

Order–disorder transition in a two-dimensional boron–carbon–nitride alloy
Two-dimensional boron–carbon–nitride materials exhibit a spectrum of electronic properties ranging from insulating to semimetallic, depending on their composition and geometry. Detailed experimental insights i...

Article
Wnt5a uses CD146 as a receptor to regulate cell motility and convergent extension
Dysregulation of Wnt signalling leads to developmental defects and diseases. Non-canonical Wnt signalling via planar cell polarity proteins regulates cell migration and convergent extension; however, the under...

Article
Open AccessFluorescence detecting of paraquat using host-guest chemistry with cucurbit[8]uril
Paraquat (PQ) is one of the most widely used herbicides in the world, which has a good occupational safety record when used properly. While, it presents high mortality index after intentional exposure. Acciden...

Open AccessSingle-shot measurement of >1010 pulse contrast for ultra-high peak-power lasers
Real-time pulse-contrast observation with a high dynamic range is a prerequisite to tackle the contrast challenge in ultra-high peak-power lasers. However, the commonly used delay-scanning cross-correlator (DS...

Inhibition of endothelial ERK signalling by Smad1/5 is essential for haematopoietic stem cell emergence
The earliest HSCs are derived from haemogenic endothelium via endothelial-to-haematopoietic transition during vertebrate embryogenesis; however, the underlying mechanism is largely unclear. Here we show that i...

Open AccessLong-term Follow-up of Therapeutic ERCP in 78 Patients Aged 90 Years or Older
This study aimed to determine the performance and long-term outcomes of therapeutic ERCP in very old patients. Patients aged or over 90 (Group A, n = 78) and consecutive sex-matched controls (Group B, n = 312)...

Open AccessOmics-based interpretation of synergism in a soil-derived cellulose-degrading microbial community
Reaching a comprehensive understanding of how nature solves the problem of degrading recalcitrant biomass may eventually allow development of more efficient biorefining processes. Here we interpret genomic and...

Open AccessNew localized/delocalized emitting state of Eu2+ in orange-emitting hexagonal EuAl2O4
Eu2+-activated phosphors are being widely used in illuminations and displays. Some of these phosphors feature an extremely broad and red-shifted Eu2+ emission band; however, convincing explanation of this phenome...

Open AccessFormation of quantum spin Hall state on Si surface and energy gap scaling with strength of spin orbit coupling
For potential applications in spintronics and quantum computing, it is desirable to place a quantum spin Hall insulator [i.e., a 2D topological insulator (TI)] on a substrate while maintaining a large energy g...

Open AccessA genome scan revealed significant associations of growth traits with a major QTL and GHR2 in tilapia
Growth is an important trait in animal breeding. However, the genetic effects underpinning fish growth variability are still poorly understood. QTL map** and analysis of candidate genes are effective methods...
