With the rapid development of AR technology, the need for lightweight and high‐brightness displays has become crucial. MicroLED technology is one of the few feasible solutions for this. The requirements of achieving ultra‐high PPI, integrating RGB full colors, and reducing the chip size to less than 3μm on a CMOS backplane present significant challenge. This paper will discuss the fabrication of a full‐color, high‐PPI micro‐display. [ABSTRACT FROM AUTHOR]

In the aftermath of the 2022 Russian–Ukrainian war, Taiwan experienced economic shocks that prompted the government to initiate the happiness lunchbox program, aimed at fostering sustainable development and zero hunger concerns. Despite these efforts, economically disadvantaged university students faced challenges due to the unconventional outsourcing of campus meals. This study, conducted by leveraging campus culinary facilities, adopts an inferred value approach as opposed to the subjective willingness-to-pay (WTP) method, providing a more conservative assessment of students' willingness to contribute. Through regression analysis, this study highlights the positive correlation between student engagement in charitable activities and WTP for student-led events. This involvement not only enhances food safety and hygiene but also reflects a genuine commitment to supporting financially challenged students. The comprehensive nature of this approach effectively tackles issues related to campus nutrition, emphasizing the significance of establishing a sustainable campus environment to achieve objectives such as "zero hunger" and "responsible consumption and production" on campus.

Background: Endovascular thrombectomy (EVT) for acute ischemic stroke associated with tandem lesion is challenging. Achieving rapid intracranial revascularization and managing the extracranial lesion without complications are the main challenges. Materials and Methods: The balloon angioplasty followed by aspiration of large-vessel occlusion (BAFALO) technique was used to address this clinical issue. A review of a prospectively maintained stroke registry from January 2015 to April 2020 was performed. Patients had stroke with TO and treated with the BAFALO technique were included. Results: Twelve patients were enrolled: 11 had anterior circulation stroke, and 1 had posterior circulation stroke. There were 10 ipsilateral internal carotid artery stenosis/occlusion, one left common carotid artery to subclavian artery bypass stenosis, and 1 vertebral artery orifice stenosis. The median National Institutes of Health Stroke Scale score was 16 (interquartile range [IQR]: 14–16). Revascularization with a Modified Thrombolysis in Cerebral Infarction score of 2b or more was achieved in 11 (92%) patients. The median puncture-to-revascularization time was 25 min (IQR: 19.5–31). Emergent stent implantation was performed in five (42%) patients. Three had distal protection devices (DPDs) with no distal embolization. Two patients did not use a DPD, and one had intracranial reocclusion. Eight (67%) proximal stenotic vessels remained patent. No symptomatic intracranial hemorrhage occurred. Eight (67%) patients had favorable clinical outcomes (modified Rankin Score 0–2 at 90 days). Conclusion: While managing TO, the BAFALO technique could achieve rapid intracranial revascularization and treat extracranial lesions under embolic protection. These merits translate into favorable clinical outcomes. [ABSTRACT FROM AUTHOR]

Background and Objectives: Hydrocephalus is characterized by progressive enlargement of cerebral ventricles, resulting in impaired microvasculature and cerebral hypoperfusion. This study aimed to demonstrate the microvascular changes in hydrocephalic rats and the effects of cerebrospinal fluid (CSF) release on cerebral blood flow (CBF)., Methods: On postnatal day 21 (P21), male Wistar rats were intracisternally injected with either a kaolin suspension or saline. On P47, Evan's ratio (ER) was measured using MRI. On P49, the arteriolar diameter and vascular density of the pia were quantified using a capillary video microscope. The CBF was measured using laser Doppler flowmetry. The expressions of NeuN and glial fibrillary acidic protein determined by immunochemical staining were correlated with the ER. The CBF and rotarod test performance were recorded before and after CSF release. The expressions of 4-hydroxynonenal (4-HNE) and c-caspase-3 were studied on P56., Results: Ventriculomegaly was induced to varying degrees, resulting in the stretching and abnormal narrowing of pial arterioles, which regressed with increasing ER. Quantitative analysis revealed significant decreases in the arteriolar diameter and vascular density in the hydrocephalic group compared with those in the control group. In addition, the CBF in the hydrocephalic group decreased to 30%-50% of that in the control group. In hydrocephalus, the neurons appear distorted, and the expression of 4-HNE and reactive astrogliosis increase in the cortex. After CSF was released, improvements in the CBF and rotarod test performance were inversely associated with the ER. In addition, the levels of 4-HNE and c-caspase-3 were further elevated., Conclusion: Rapid ventricular dilatation is associated with severe microvascular distortion, vascular regression, cortical hypoperfusion, and cellular changes that impair the recovery of CBF and motor function after CSF release. Moreover, CSF release may induce reperfusion injury. This pathophysiology should be taken into account when treating hydrocephalus., (Copyright © Congress of Neurological Surgeons 2024.
