We have demonstrated balanced coherent detection using distributed balanced traveling-wave photodetectors integrated with single mode polymer optical waveguides. Balanced distributed traveling-wave photodetectors having 3 dB bandwidth of 20 GHz exhibited 20 dB signal to noise ratio improvement measured at 15 GHz modulation frequency in a balanced coherent detection demonstration.

Diverse phenotype of Ménière's disease associated with family history, thyroid disorder, migraine and associated disorders.

Objective: To better understand the clinical phenotype of Ménière's disease (MD), we examined family history, thyroid disorder, migraine, and associated disorders in complaints of people living with MD.
Method: We designed the study as a retrospective and examined data gathered from 912 participants with MD. Their data were originally collected by the Finnish Ménière Federation (FMF).

Magnetotransport of conventional semiconductor based double layer systems with barrier suppressed interlayer tunneling has been a rewarding subject due to the emergence of an interlayer coherent state that behaves as an excitonic superfluid. Large angle twisted bilayer graphene offers unprecedented strong interlayer Coulomb interaction, since both layer thickness and layer spacing are of atomic scale and a barrier is no more needed as the twist induced momentum mismatch suppresses tunneling. The extra valley degree of freedom also adds richness.

Article Synopsis
- The study aimed to analyze how antiphase trunk motion affects quiet stance stability without changes in visual or surface conditions.
- Wearing a rigid orthotic brace that limited trunk motion, researchers compared sway characteristics across different brace conditions.
- Findings revealed that allowing antiphase motion reduced trunk and leg sway velocities and highlighted the relationship between trunk movement and ankle torque, suggesting that this motion is crucial for maintaining balance, especially in predicting postural issues due to various factors.
CO Sequestration Technologies May Undermine China's Sustainable Development Goals through the Climate-Energy-Air-Health Cascade.

CO sequestration technologies (CSTs) allow for increased CO emissions without exceeding a chosen temperature limit by creating additional carbon budgets. While these CO sequestration technologies offer low-cost routes to net-zero emissions, namely, the CST benefits, they impede progress to the Sustainable Development Goals, namely, the CST disbenefits. Focusing on China, we assess both the CST disbenefits and benefits in the climate-energy-air-health cascade by an integrated modeling framework.

This article presents a qualitative, quantitative, and experimental analysis of optical coherence tomography (OCT) volumes obtained using different families of non-raster trajectories. We propose a multicriteria analysis to be used in the assessment of scan trajectories used in obtaining OCT volumetric point cloud data. The novel criteria includes exploitation/exploration ratio of the OCT data obtained, smoothness of the scan trajectory and fast preview of the acquired OCT data in addition to conventional criteria; time and quality (expressed as volume similarity rather than slice-by-slice image quality).
