Besides, the image quality is compromised due to the biosafety limitation of the laser.

Refractive index and temperature dual-parameter sensors based on loss mode resonance and directional coupler in side-polished hole-assisted dual-core fiber.

A refractive index (RI) and temperature dual-parameter sensor, based on a side-polished hole-assisted dual-core fiber (HADCF), has been proposed. In this sensor, SnO film has been deposited on the suspended core of HADCF by RF sputtering to produce loss mode resonance (LMR). The energy of the center core has been shown to be able to be coupled into the suspended core, taking advantage of the small distance involved and phase matching between two cores.

Generation of leaky mode resonance and lossy mode resonance with the same optical platform.

Leaky mode resonance (LMR) and lossy mode resonance (LMR) refer to two different surface waves but are easily confused. Herein, we comprehensively investigated the excitation mechanism and sensing performance of both LMR and LMR with the same prism-film-surrounding platform based on the rigorous transfer matrix method. Both non-absorbing film waveguides, absorbing film waveguides, and gold-cladding film waveguides were analyzed.

Enhanced sensitivity of refractive-index-sensing optical frequency comb using frequency multiplication capability of photocarrier terahertz frequency comb for rapid measurement.

We propose a refractive index (RI) sensing method that leverages the frequency multiplication capability of a photocarrier terahertz (PC-THz) comb to enhance sensitivity and speed. By incorporating a PC-THz comb as a frequency multiplier for a RI-sensing optical frequency comb (OFC), we achieve significant amplification of the RI-dependent mode spacing ( ) shift. Our results show a 3100-fold increase in sensitivity, confirmed through the accurate measurement of ethanol-water solutions with varying concentrations.

Functional nanocrystal as effective contrast agents for dual-mode imaging: Live-cell sonoluminescence and contrast-enhanced echography.

In the context of molecular imaging, the present work explores an innovative platform made of lipid-coated nanocrystals as contrast-enhanced agent for both ultrasound imaging and sonoluminescence. At first, the dynamics of gas bubbles generation and cavitation under insonation with either pristine or lipid-coated nanocrystals (ZnO-Lip) are described, and the differences between the two colloidal systems are highlighted. These ZnO-Lip show an unprecedented ability to assist cavitation, which is reflected in enhanced sonoluminescent light emission with respect to the pristine nanocrystals or the pure water.

Symmetrical dual-D and dual-core single-mode fiber surface plasmon resonance liquid sensor.

A symmetrical dual-D and dual-core single-mode fiber surface plasmon resonance (SPR) liquid sensor is designed for biological detection. The dual-core design optimizes the transmission path, improves the momentum matching between free electrons and photons, and facilitates bidirectional coupling, consequently amplifying the SPR effect and enabling sensitive monitoring of the refractive index changes of biological solutions. In this structure, a gold wire is placed in the middle of the polished surface of the double-D-shaped single-mode fiber (SMF) to produce high-quality free electrons and promote the mode-coupling excitation of the SPR effect.

Preoperative low prealbumin independently predicts non-gastric cancer death after gastrectomy in elderly and young patients: a retrospective cohort study.

Purpose: To investigate the effect of preoperative prealbumin levels on long-term survival outcomes after gastrectomy in patients with gastric cancer (GC) dichotomized based on age.

Methods: This retrospective cohort study included consecutive patients who underwent radical gastrectomy for primary stage I-III GC between May 2006 and March 2017. Patients were allocated to groups based on age (≥ 70 or < 70 years) and subgroups based on prealbumin levels (high, ≥ 22 mg/dL; moderate, 15-22 mg/dL; or low, < 15 mg/dL), and multivariate Cox regression was used for survival analyses.

The transcriptional response of cortical neurons to concussion reveals divergent fates after injury.

Traumatic brain injury (TBI) is a risk factor for neurodegeneration, however little is known about how this kind of injury alters neuron subtypes. In this study, we follow neuronal populations over time after a single mild TBI (mTBI) to assess long ranging consequences of injury at the level of single, transcriptionally defined neuronal classes. We find that the stress-responsive Activating Transcription Factor 3 (ATF3) defines a population of cortical neurons after mTBI.

Involvement of aSPOC in the online updating of reach-to-grasp to mechanical perturbations of hand transport.

Humans adjust their movement to changing environments effortlessly via multisensory integration of the effector's state, motor commands, and sensory feedback. It is postulated that frontoparietal (FP) networks are involved in the control of prehension, with dorsomedial (DM) and dorsolateral (DL) regions processing the reach and the grasp, respectively. This study tested (5F, 5M participants) the differential involvement of FP nodes (ventral premotor cortex - PMv, dorsal premotor cortex - PMd, anterior intraparietal sulcus - aIPS, and anterior superior parietal-occipital cortex - aSPOC) in online adjustments of reach-to-grasp coordination to mechanical perturbations that disrupted arm transport.
