Study on Accuracy Improvement of Slope Failure Region Detection Using Mask R-CNN with Augmentation Method.

We proposed an automatic detection method of slope failure regions using a semantic segmentation method called Mask R-CNN based on a deep learning algorithm to improve the efficiency of damage assessment in the event of slope failure disaster. There is limited research on detecting landslides by deep learning, and the lack of training data is an important issue to be resolved, as aerial photographs are not taken with sufficient frequency during a disaster. This study attempts to use CutMix-based augmentation to improve detection accuracy.

Insights into the Formation Pathway of Templated Ordered Nanostructured Carbonaceous Particles under Hydrothermal Conditions.

Ordered nanostructured materials and their porous counterparts are important for numerous applications in sorption and separation sciences, electrochemistry, catalysis, and photonics. They can be synthesized by introducing surfactant or amphiphilic polymer template(s) into the condensation stage of a developing solid. Understanding the pathways involved in the formation of these materials is of great interest and will help in the development of future synthesis schemes for designing nanomaterials with controlled nanostructures, pore sizes and shapes, and particle morphologies.

Insight into Notch Signaling Steps That Involve from Dominant-Modifier Screens in .

Notch signaling plays crucial roles in intercellular communications. In , the () gene, which encodes an evolutionarily conserved multi-pass transmembrane protein, appears to be required to activate Notch signaling in some contexts, especially during neuroblast segregation in the neuroectoderm. Although Pcx has been suggested to contribute to endoplasmic reticulum homeostasis, its functions remain unknown.

Porous carbohydrate-based materials via hard templating.

Among various techniques, the hydrothermal carbonization (HTC) of biomass (either isolated carbohydrates or crude plants) is a promising candidate for the synthesis of novel carbon-based materials with a wide variety of potential applications. In this Minireview, we discuss various synthetic routes towards such porous carbon-based materials or composites through the HTC process, using the nanocasting procedure. We focus on the synthesis of carbon materials with different pore systems and morphologies directed by the presence of various nanostructured inorganic sacrificial templates.

Salt-induced formation of uniform fiberlike SBA-15 mesoporous silica particles and application to toluene adsorption.

Long, homogeneous fiberlike SBA-15 mesoporous silica particles are prepared by fine adjustment of three reaction conditions--stirring temperature, stirring time, and amount of inorganic salt added--using Pluronic P123 and TEOS under acidic conditions. The addition of NaCl along with a short stirring time played an important role in controlling the morphology and pore characteristics. Dynamic adsorption performance for gaseous toluene was systematically evaluated using four types of materials with different morphologies and pore characteristics synthesized with the addition of a different amount of NaCl.

Effect of pore structure in mesoporous silicas on VOC dynamic adsorption/desorption performance.

The dynamic adsorption/desorption behavior of volatile organic compounds (VOCs) such as toluene (C7H8) and benzene (C6H6) was evaluated for three kinds of mesoporous silicas of SBA-15, all having almost the same mesopore size of ca. 5.7 nm, and a MCM-41 silica with a smaller pore size of 2.
