Quantum Frequency Translation of Single-Photon States in Photonic Crystal Fiber

open access: yes, 2010
We experimentally demonstrate frequency translation of a nonclassical optical field via the Bragg scattering four-wave mixing process in a photonic crystal fiber (PCF).

‘Candidatus Liberibacter Asiaticus’ Effector SECP8 Subverts Salicylic Acid‐Mediated Citrus Immunity via a Two‐Pronged Impairment of CsTCP15 Dimerization

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Citrus Huanglongbing (HLB), a devastating disease caused by the unculturable bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), poses a severe threat to global citrus production. CLas secretes effectors to suppress host immune responses and facilitate its colonisation. Previously, the CLas effector SECP8 (CLIBASIA_05330) has been identified

The miR319/bHLH094 Module Regulates Creeping Bentgrass Thermotolerance by Modulating Auxin Biosynthesis and Signalling Pathway

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT MicroRNA319 (miR319) has been demonstrated to regulate plant development and responses to stress such as drought and salt. However, its role in thermotolerance, particularly in cool season grasses, remains unclear. Here we report that miR319 plays a negative role in heat tolerance of creeping bentgrass (Agrostis stolonifera).

Health and Survival Impacts of Early Childhood Development Programmes: The Case of the Happy Child Programme in Brazil

open access: yesReview of Development Economics, EarlyView.
ABSTRACT This paper adds to the growing evidence on the impacts of early childhood development (ECD) programming by examining one of the world's largest home visitation programmes, the Happy Child Programme in Brazil, and its impacts on child vaccination and preventable death rates.

The PCF Theorem Revisited

open access: yes, 1997
The pcf theorem (of the possible cofinality theory) was proved for reduced products prod_{i< kappa} lambda_i/I, where kappa < min_{i< kappa} lambda_i. Here we prove this theorem under weaker assumptions such as wsat(I)< min_{i< kappa} lambda_i, where wsat(I) is the minimal theta such that kappa cannot be delivered to theta sets notin I ...

Impact of a 12‐week high‐intensity interval training intervention on cardiac structure and function after COVID‐19 at 12‐month follow‐up

open access: yesExperimental Physiology, EarlyView.
Abstract In patients previously hospitalised for COVID‐19, a 12‐week high‐intensity interval training (HIIT) intervention has previously been shown to increase left ventricular mass (LVM) immediately after the intervention. In the present study, we examined the effects of the same HIIT scheme on LVM, pulmonary diffusing capacity, symptom severity and ...

Endoscopic features of deficient mismatch repair/microsatellite instability‐high and BRAF‐mutated colorectal cancer

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
Abstract Objective Recent advancements in genome analyses, including the BRAF gene and mismatch repair (MMR) gene/microsatellite instability (MSI), have revealed the biological diversity of colorectal cancer (CRC). BRAF‐mutated CRC has a poor prognosis; however, cases exhibiting deficient MMR (dMMR)/MSI‐high (MSI‐H) and BRAF gene mutations have ...

The Risk of Colonoscopy‐related Bleeding in Patients With or Without Continued Treatment With an Antithrombotic Agent

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives We prospectively investigated the risk of colonoscopy‐related bleeding in relation to antithrombotic treatment. Methods This prospective, observational, single‐center cohort study (NCT02594813) enrolled consecutive patients who underwent colonoscopy, including the removal of colorectal polyps, regardless of the continuation of ...

Quantification and Clinical Correlation of Posterior Cranial Fossa Cerebrospinal Fluid Volume in Primary Hemifacial Spasm Using Magnetic Resonance Imaging

open access: yesAnnals of Indian Academy of Neurology
Background and Objective: Primary hemifacial spasm (HFS) is caused by neurovascular conflict (NVC) at the root entry zone of the facial nerve. Whether reduction of posterior cranial fossa (PCF) cerebrospinal fluid (CSF) volume is a risk factor for HFS is
