Cerebral arteries are responsible for providing sufficient blood supply, which is dependent on systemic blood pressure and thus cardiac output. Cerebral capillaries play a critical role in delivering blood to meet the local needs of neural activity. Their narrow lumen interacts with blood cells, creating resistance to blood flow in the parenchymal tissue. Therefore, the relationship between arterial blood pressure and capillary resistance is critical in determining blood perfusion in the brain. However, the regulatory mechanism of capillary resistance has received less attention compared to the management of arterial blood pressure in maintaining healthy cerebral perfusion. This article summarizes the methodological contributions of optical imaging to the characterization of capillary resistances by microvascular function in the brain, including: i) three-dimensional imaging and quantification methods used in preclinical studies to determine spatial variations in microvascular structures in the cortex, ii) fluorescence imaging techniques for mapping the temporal dynamics of microvascular flow, and iii) understanding microvascular function in response to global changes induced by systemic physiology and local variations in neural network activities. Finally, potential technical advances in optical tools for diagnosis of brain microvascular function are discussed.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 4: Adv. in Neurophoton. for Non-Inv.

The continuously upgraded functional PDRC materials have further promoted the application of radiation cooling technology in real-world applications. This review explores the design evolution of PDRC materials, structures, and systems from sole-function to multifunctional designs, emphasizing their potential to achieve both high solar reflectance and strong thermal emittance for optimal cooling performance. Among them, multifunctional PDRC materials or systems with self-cleaning, fire-resistant, switchable, and evaporated-coupled characteristics are presented. Future challenges and opportunities for advancing PDRC materials are also discussed, aiming to guide the development of scalable solutions that can facilitate the large-scale production and application of this sustainable cooling technology.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 6: Photon. for Climate Chng.

WGN generation relies heavily on random numbers. In this work, we present an implementation of WGN generation utilizing a quantum entropy source chip for the first time. A photonic integrated chip based on the vacuum state scheme generates quantum random numbers at a real-time output rate of up to 6.4 Gbps. A hardware-based inversion method converts uniform quantum random numbers into Gaussian random numbers using the inverse cumulative distribution function. Subsequently, the WGN signal is generated through a digital-to-analog converter and amplifiers. The WGN generator is characterized by a bandwidth of 230 MHz, a crest factor as high as 6.2, and an adjustable peak-to-peak range of 2.5 V. This work introduces a novel approach to WGN generation with information-theory provable quantum random numbers to enhance system security.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 5: Quantum Materials and Quantum Devices","pages":"1-8"},"PeriodicalIF":4.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-two young migraines and thirty-two healthy control subjects (HC) were measured by fNIRS to observe changes in hemoglobin in the prefrontal cortex (PFC). According to the structural changes in the frontal cortex in migraine patients, two mental stress tasks and a concentration task (CT) were designed. The statistical findings showed that all three tasks revealed differences in prefrontal blood oxygenation between groups. Specifically, during the mental task-related exercises, a significant difference was identified in the left hemisphere, whereas during the CT, a notable distinction was noted in the right hemisphere. Furthermore, machine learning techniques were applied for migraine classification, receiving test accuracies of 82%, 89%, and 90% for the mental arithmetic task (MAT), the verbal fluency task (VFT), and the CT, respectively. These results demonstrate the feasibility of utilizing fNIRS with machine learning to classify migraines in young individuals.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 4: Adv. in Neurophoton. for Non-Inv.

Different types of polarized light exhibit distinct interference behaviors, making the systematic study of these behaviors crucial. This paper introduces the concept of the polarization two-photon coherence matrix and provides a theoretical explanation for the differences in two-photon interference phenomena among linear, circular, and elliptically polarized light. Using a polarization Michelson interferometer based on two-photon absorption detection, second-order interference images of circularly polarized and elliptically polarized light were experimentally captured. The differences in these two-photon interference phenomena can be elucidated by visualizing the polarization coherence matrix. Furthermore, this theory was applied to the study of sub-wavelength interference phenomena of circularly polarized light, confirming the universality of the theoretical model and offering new perspectives and tools for the study of quantum optics.","PeriodicalId":13094,"journal":{"name":"IEEE Journal of Selected Topics in Quantum Electronics","volume":"31 5: Quantum Materials and Quantum Devices","pages":"1-9"},"PeriodicalIF":4.3,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
