We propose a new type of all-fiber mode scrambler for mode division multiplexed data transmission based on few mode fibers. By randomly placing multiple point-loads along the fiber length, low loss and wideband mode coupling is obtained amongst all the guided modes. The effect of mode coupling is si...

Based on the polarization interference technique, we propose a modified method for simultaneously measuring the beat length of all guided modes in a polarization-maintaining few-mode fiber (PM-FMF). We experimentally demonstrate the effectiveness of our proposed method on a 3-mode PANDA-type PM-FMF....

Using principal modes (PMs) can avoid the inter-mode crosstalk in fiber-optic communication and reduce the complexity of digital signal processing. In this paper, a new detection method for PMs based on spatially and spectrally resolved imaging (S²) is used to recover their in...

BackgroundPrimary ciliary dyskinesia (PCD) is a genetically heterogeneous ciliopathy caused by structural and functional abnormalities of motile cilia. Although over 50 PCD-associated genes have been reported, the genetic spectrum remains incomplete. CFAP47, a gene linked to multiple morphological a...

Exploring innovative approaches to enhance the performance of photonic lanterns is greatly valuable. In this paper, we first propose an air-hole-assisted pure silica-based capillary (AHC), featuring a single ring of embedded air holes. As a result, the PL based on the AHC exhibits good performance,...

Three cases of structural-stratigraphic accumulations in the foredeep zone of the Oriente Basin have been analyzed. The target reservoirs are U and M1 sections of Napo Fm. in the Basin. Seismic amplitude maps are used for sand distribution pattern, and wells interpretation and correlations are appli...

Drought impacts agricultural production and regional sustainable development. Accordingly, timely and accurate drought monitoring is essential for ensuring food security in rain-fed agricultural regions. Alternating drought and flood events frequently occur in the Heilongjiang River Basin, the large...

Objectives: Tuberculosis (TB) poses a significant threat to global public health, particularly, among elderly individuals. This study aimed to provide a comprehensive analysis of the patterns and temporal trends in the global disease burden of HIV-negative TB among adults aged ≥60 years from 1990 to...
