    Abstract Mid-ultraviolet light (290-320 nm) can promote human vitamin D synthesis, which helps in the prevention and treatment of rickets and cartilage disease. For people who lack sufficient ultraviolet radiation all year round, it is significant to supplement the ultraviolet component in daily lighting sources. However, there are few luminous materials showing a combination of mid-ultraviolet light and white light emission on the market. Here, we designed a new material, Y

    Abstract Nonspecific interactions play a significant role in physiological activities, surface chemical modification, and artificial adhesives. However, nonspecificity sometimes causes sticky problems, including surface fouling, decreased target specificity, and artifacts in single-molecule measurements. Adjusting the liquid pH, using protein-blocking additives, adding nonionic surfactants, or increasing the salt concentration are common methods to minimize nonspecific binding to achieve high-quality data. Here, we report that grafting heteromorphic polyethylene glycol (Y-shape PEG) with two inert terminates could noticeably decrease nonspecific binding. As a proof-of-concept, we performed single-molecule force spectroscopy and fluorescence staining imaging experiments to verify the feasibility of Y-shape PEG in blocking nonspecific interactions. Our results indicate that Y-shape PEG could serve as a prominent and efficient candidate to minimize nonspecificity for scientific and biomedical applications.

    Abstract Introduction: Sympathetic nervous system disorder promotes atrial fibrillation (AF), and neuropeptide Y (NPY) is an important neurotransmitter. This study aimed to explore the predictive value of plasma NPY in patients with AF.
    Methods: Five hundred seventy-six patients were divided into AF (including paroxysmal and long-standing persistent AF; 360) and sinus rhythm (SR) groups (216). NPY level was detected using enzyme-linked immunosorbent assay, and NPY mRNA expression level was detected using quantitative polymerase chain reaction. Logistic regression was used to analyse the risk factors for AF; the correlations between blood NPY level and age, body mass index (BMI), left ventricular ejection fraction, left atrial diameter (LAD), and European Heart rate Association (EHRA) score in patients with AF were determined. The receiver operating characteristic (ROC) curve was utilised to predict AF.
    Results: Plasma NPY levels were found to be higher in patients with AF than in patients with SR and in patients with long-standing persistent AF than in patients with paroxysmal AF; blood NPY mRNA levels were higher in the paroxysmal and long-standing persistent AF groups compared to the SR group (p < 0.05). Increased age {odds ratio (OR) = 1.201 (95% confidence interval [CI]: 1.01, 1.427)} and high NPY [OR = 1.239 (95% CI: 1.022, 1.501)] were factors found to affect AF detrimentally. NPY was associated with BMI (r = 0.5856, p < 0.05), LAD (r = 0.4023, p < 0.05), and EHRA score (r = 0.898, p < 0.05). The ROC curve for the predictive value of plasma NPY levels for AF showed an area under the curve (AUC) value of 0.919 (p < 0.05), while that for long-standing persistent AF showed an AUC of 0.784 (p < 0.05).
    Conclusion: Circulating NPY may be a promising molecular biomarker of AF.

    Abstract Growing research interests have been directed to the emerging optical communication band at 2-µm wavelengths. The silicon photonic components are highly desired to operate over a broad bandwidth covering both C-band and the emerging 2-µm wave band. However, the dispersions of the silicon waveguides eventually limit the optical bandwidth of the silicon photonic devices. Here, we introduce a topology-optimized Y-junction with a shallow-etched trench and its utility to reverse the detrimental dispersion effect. The shallow trench enables the Y-junction to have an adaptive splitting capability over a broad spectral range. The 0.2-dB bandwidth of the power splitter exceeds 800 nm from 1400 nm to 2200 nm. The device has a compact footprint of 3 µm × 1.64 µm. The device is characterized at the C-band and 2-µm band with a measured excess loss below 0.4 dB for a proof-of-concept demonstration.

    Abstract: ... a modified V-Y advancement flap will be introduced that will avoid the complications discussed above as well ... the reverse V-Y advancement method can be used to enlarge the nostril.: Methods ... with a modified V-Y advancement flap on 65 female patients ranging from 18 to 45 years of age. In 10 cases ...

    Abstract Background: A variety of techniques for alar base modification have been described in the literature. Limitations of these techniques include scars, recurrence, asymmetry, etc. An incorrect excision of the lateral alar wall can result in a tear-drop or Q-shaped deformity.
    Objectives: In this study, a modified V-Y advancement flap will be introduced that will avoid the complications discussed above as well as adjust the positional relationship between the nasal alar and the columella using this technique. In addition, this method is reversible; once the nostril is narrow due to excessive advancement of the flap, the reverse V-Y advancement method can be used to enlarge the nostril.
    Methods: In this study, a retrospective review of wide nasal bases in the past 3 years was conducted. A blind analysis of anthropometric points was conducted. There were 3 outcome variables: the width of the alar base, the width of the flare, and the distance between the alar base and columellar base.
    Results: The alar base was reduced with a modified V-Y advancement flap on 65 female patients ranging from 18 to 45 years of age. In 10 cases, an "Inclined Y-arm flap" was used to narrow alar bases and adjust columella-alar positions. In the remaining cases, a "Horizontal Y-arm flap" was performed to narrow the simple nasal alar width. In all cases, the nasal base was reduced without distortion. In the postoperative period, all the effects were seen to persist for a long time, and patients were generally satisfied with the results of the procedure.
    Conclusion: By using this modified V-Y advancement flap technique, the incision can be concealed as thoroughly as possible, thereby avoiding "tear-drop" or "Q" deformities as well as narrowing the nasal alar effectively. Furthermore, this method, in combination with rhinoplasty surgery, will greatly enhance the nasal appearance.

    Abstract Herein, micron-sized silver particles were prepared using the chemical reduction method by employing a Y-type microjet reactor, silver nitrate as the precursor, ascorbic acid as the reducing agent, and gelatin as the dispersion at room temperature (23 °C ± 2°C). Using a microjet reactor, the two reaction solutions collide and combine outside the reactor, thereby avoiding microchannel obstruction issues and facilitating a quicker and more convenient synthesis process. This study examined the effect of the jet flow rate and dispersion addition on the morphology and size of silver powder particles. Based on the results of this study, spherical and dendritic silver particles with a rough surface can be prepared by adjusting the flow rate of the reaction solution and gelatin concentration. The microjet flow rate of 75 mL/min and the injected gelatin amount of 1% of the silver nitrate mass produced spherical ultrafine silver particles with a size of 4.84 μm and a tap density of 5.22 g/cm
