Photon Frequency Mode Matching using Acousto-Optic Frequency Beam Splitters [PDF]

open access: yes, 2005
It is a difficult engineering task to create distinct solid state single photon sources which nonetheless emit photons at the same frequency. It is also hard to create entangled photon pairs from quantum dots.

Disordered Carbon Shells Enable Shape Dependent Fluorescence Enhancement in Nanodiamond Quantum Sensors Revealed by Correlative TEM–Fluorescence Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Molten KNO2 treatment induces a lowrefractive index disordered carbon shell on fluorescent nanodiamonds, enhancing fluorescence emission while preserving spin coherence. Machine learningassisted correlative TEMPL enables direct single‐particle resolution of this enhancement relative to air‐oxidized nanodiamonds of similar morphology, establishing a ...

AOM in children.

open access: yesBMJ clinical evidence, 2011
INTRODUCTION: In the UK, about 30% of children under 3 years of age visit their GP each year with acute otitis media (AOM), and 97% of these receive antibiotics. In the US, AOM is the most common reason for outpatient antibiotic treatment. Without antibiotics, AOM resolves within 24 hours in about 60% of children, and within 3 days in about 80% of ...

Gut Mycobiota‐Associated Tryptophan Catabolites Protect Against Metabolic Dysfunction‐Associated Steatotic Liver Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Accumulating evidence suggests that the intestinal microbiota participates in the progression of metabolic dysfunction‐associated steatotic liver disease (MASLD) through microbiota‐host interaction. However, the beneficial role of commensal mycobiota in MASLD progression remains poorly understood.

Efficacy of a non-invasive middle ear aeration device in children with recurrent otitis media: A randomized controlled trial protocol

open access: yesContemporary Clinical Trials Communications, 2018
Acute otitis media (AOM) represents a significant disease burden in the pediatric population. Besides vaccinations, there are no robust measures of reducing incidence of AOM in this age-group. This is a randomized controlled clinical trial evaluating the

New Approaches and Technologies to Improve Accuracy of Acute Otitis Media Diagnosis

open access: yesDiagnostics, 2021
Several studies have shown that in recent years incidence of acute otitis media (AOM) has declined worldwide. However, related medical, social, and economic problems for patients, their families, and society remain very high.

Comment on ``Manipulating the frequency entangled states by an acoutic-optical modulator''

open access: yes, 2000
A recent theoretical paper [1] proposes a scheme for entanglement swapping utilizing acousto-optic modulators without requiring a Bell-state measurement.

Targeting Peptostreptococcus anaerobius with an Iron‐Based Nanozyme Reverses Ferroptosis Resistance and Enhances Antitumor Immunity in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
An iron‐based nanozyme selectively eliminates intratumoral P. anaerobius while catalytically generating ROS to induce ferroptosis, synergistically suppressing colorectal cancer growth and activating anti‐tumor immunity through immunogenic cell death. ABSTRACT The intratumoral microbiota is a critical determinant of therapeutic outcomes in colorectal ...

Particular matter influences the incidence of acute otitis media in children

open access: yesScientific Reports, 2021
Particulate matter (PM) is the main component of air pollution. Children are vulnerable to PM and acute otitis media (AOM), which is one of the most common diseases in children. However, studies on the relationship between AOM in children and PM are rare

Coherent analysis of quantum optical sideband modes

open access: yes, 2005
We demonstrate a device that allows for the coherent analysis of a pair of optical frequency sidebands in an arbitrary basis. We show that our device is quantum noise limited and hence applications for this scheme may be found in discrete and continuous ...
