Design of portable emergency lamp utilizing thin film solar cell and inflatable case

open access: yesE3S Web of Conferences, 2018
Lighting is an essential thing in performing daily activities and without sufficient lighting we will be difficult to see clearly. The problem is when there is no electricity, for example when we go to a cave or a forest or when there is a natural ...

Performance Comparison of Tungsten-Halogen Light and Phosphor-Converted NIR LED in Soluble Solid Content Estimation of Apple

open access: yesSensors, 2023
A Tungsten-Halogen (TH) lamp is the most popular light source in NIR spectroscopy and hyperspectral imaging, which requires a warm-up to reach very high temperatures of up to 250 °C and take a long time for radiation stabilization. Consequently, it has a

Cyan-Green Phosphor (Lu2M)(Al4Si)O12:Ce3+ for High-Quality LED Lamp: Tunable Photoluminescence Properties and Enhanced Thermal Stability.

open access: yesInorganic Chemistry, 2018
High-quality white light-emitting diodes (w-LEDs) are mainly determined by conversion phosphors and the enhancement of cyan component that dominates the high color rendering index.

Ubiquitination of secretory granules promotes their crinophagic degradation in Drosophila

open access: yesFEBS Letters, EarlyView.
Ubiquitination of secretory granules in Drosophila larval salivary glands is a critical molecular trigger for crinophagy, the lysosomal degradation of unreleased, or low‐quality granules. The E3 ubiquitin ligase Cnot4 is recruited to the surface of secretory granules to induce crinophagy.

Phenotypic and genotypic characterization of single circulating tumor cells in the follow‐up of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, Volume 20, Issue 6, Page 1535-1555, June 2026.
Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

DESIGNING AN OFF-ROAD WORKING LAMP WITH LEDS

open access: yesElectrica, 2019
In this study a working lamp used on the off-road working machines and vehicles is designed by using the LED diodes instead of a halogen bulb. In the design, firstly a LED array is determined and a proper driver circuit that can provide the required ...
