Commodity Wi-Fi-Based Wireless Sensing Advancements over the Past Five Years.

With the compelling popularity of integrated sensing and communication (ISAC), Wi-Fi sensing has drawn increasing attention in recent years. Starting from 2010, Wi-Fi channel state information (CSI)-based wireless sensing has enabled various exciting applications such as indoor localization, target imaging, activity recognition, and vital sign monitoring. In this paper, we retrospect the latest achievements of Wi-Fi sensing using commodity-off-the-shelf (COTS) devices from the past 5 years in detail.

A metal-to-metal charge transfer induced green-yellow phosphor CsAlGeO:Bi for full-spectrum LED devices.

With the development of solid-state lighting, full-spectrum lighting has gradually received extensive attention. Until now, Bi-doped narrow-band blue phosphors have been widely reported, but broadband green-yellow Bi-doped luminescent materials generated by metal-to-metal charge transfer have been rarely reported. In this study, a Bi ion doped germanate luminescent material CsAlGeO:%Bi (1 ≤ ≤ 11) is synthesized by a high-temperature sintering method.

Hydrogen-bonded structures and low temperature transitions of the confined water in subnano channels.

The interfacial and confined water have long been attractive objects due to their crucial roles in biological, geological processes, etc. In this paper, we investigate the hydrogen-bonded structures of water and their low temperature transitions in the subnano channels of AlPO-11 for the first time on the basis of infrared spectroscopy. The number of the adsorbed water molecules is estimated to be 8.

A novel efficient red-emitting KSrYBO: Eu phosphor with non-concentration quenching and robust thermal stability for white LEDs.

Inhibiting energy migration between Eu ions in a fixed host to get higher doping concentration is a permanent topic. Herein, a novel non-concentration quenching red-emitting KSrYBO: xEu (0.1 ≤ x ≤ 1.

Ultrasensitive Pressure-Induced Optical Materials: Europium-Doped Hafnium Silicates with a Khibinskite Structure for Optical Pressure Sensors and WLEDs.

Ultrasensitive pressure-induced optical materials are of great importance owing to their potential applications in optical pressure sensors. However, the lack of outstanding pressure sensitivity, observable color evolution, and structure reliability limits their further development in both practical applications and luminescence theory. To overcome the above problems, an enlightening methodology is proposed to explore the high sensitivity and phase stability of hafnium silicate KHfSiO (KHSO) phosphor with a Khibinskite structure.

Subphrenic Lymph Node Metastasis Predicts Poorer Prognosis for Nasopharyngeal Carcinoma Patients With Metachronous Metastasis.

Aim: We retrospectively analyzed the distribution of distant lymph node metastasis and its impact on prognosis in patients with metastatic NPC after treatment.

Methods: From 2010 to 2016, 219 NPC patients out of 1,601 (182 from the Affiliated Cancer Hospital and Institute of Guangzhou Medical University, and 37 from the Affiliated Dongguan Hospital, Southern Medical University) developed distant metastasis after primary radiation therapy. Metastatic lesions were divided into groups according to location: bones above the diaphragm (supraphrenic bone, SUP-B); bones below the diaphragm (subphrenic bone, SUB-B); distant lymph nodes above the diaphragm (supraphrenic distant lymph nodes, SUP-DLN); distant lymph nodes below the diaphragm (subphrenic distant lymph nodes, SUB-DLN), liver, lung, and other lesions beyond bone/lung/distant lymph node above the diaphragm (supraphrenic other lesions, SUP-OL); other lesions beyond bone/liver/distant lymph node below the diaphragm (subphrenic other lesions, SUB-OL); the subtotal above the diaphragm (supraphrenic total lesions, SUP-TL); and the subtotal below the diaphragm (subphrenic total lesions, SUB-TL).

Prognostic value of hypertension in patients with nasopharyngeal carcinoma treated with intensity-modulated radiation therapy.

Background: The prognostic value of hypertension remains unknown in nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). In this study, we aimed to develop hypertension as a prognostic signature for improving the clinical outcome of non-metastatic NPC patients treated with IMRT.

Methods: A clinical cohort, comprising 1,057 patients with non-metastatic, histologically proven, NPC who were treated with IMRT were retrospectively reviewed.

Pressure-Induced Electronic and Structural Transition in Nodal-Line Semimetal ZrSiSe.

The nodal-line semimetals have recently gained attention as a promising material due to their exotic electronic structure and properties. Here, we investigated the structural evolution and physical properties of nodal-line semimetal ZrSiSe under pressure via experiments and theoretical calculations. An isostructural electronic transition is observed at ∼6 GPa.

A high pressure Raman study on confined individual iodine molecules as molecular probes of structural collapse in the AlPO-5 framework.

The mechanical stability of porous zeolitic materials has long been an important issue due to their advanced applications in many fields. Here, we choose to study the pressure induced structural modifications on the AlPO-5 (AFI) framework. We find that the Raman characteristics of the confined iodine molecules in the AFI channels, with a low filling density, show discontinuities at around 3 and 10 GPa, which can be attributed to the implications of framework changes.
