Efficient energy use is crucial for achieving carbon neutrality and reduction. As part of these efforts, research is being carried out to apply a phase change material (PCM) to a concrete structure together with an aggregate. In this study, an energy consumption simulation was performed using data from concrete mock-up structures. To perform the simulation, the threshold investigation was performed through the Bayesian approach. Furthermore, the spiking part of the spiking neural network was modularized and integrated into a recurrent neural network (RNN) to find accurate energy consumption. From the training-test results of the trained neural network, it was possible to predict data with an R value of 0.95 or higher through data prediction with high accuracy for the RNN. In addition, the spiked parts were obtained; it was found that PCM-containing concrete could consume 32% less energy than normal concrete. This result suggests that the use of PCM can be a key to reducing the energy consumption of concrete structures. Furthermore, the approach of this study is considered to be easily applicable in energy-related institutions and the like for predicting energy consumption during the summer.

With the rapid decline in the levelized cost, offshore wind power offers a new option for the clean energy transition of the power sector in China's coastal areas. Here, we develop a power system capacity expansion and operation optimization model to simulate the penetration of offshore wind power in China and quantify the associated health effects. We find that offshore wind power has great potential in mitigating the negative impacts of existing coal-fired power emissions.

Japanese quail () is a popular experimental animal model in scientific research. The present study investigated the effects of dietary multiple enzyme supplementation on growth performance, carcass characteristics, nutrient digestibility and small intestinal histomorphology in quails fed diets based on wheat and soya bean meal. A total number of 192 1-day-old quails were assigned to three treatments with 16 replicates in each and four quails replicate for 38 days.

Anaerobic ammonia oxidation (anammox) which converts nitrite and ammonium to dinitrogen gas is an energy-efficient nitrogen removal process. One of the bottlenecks for anammox application in wastewater treatment is the stable supply of nitrite for anammox bacteria. Dissimilatory nitrate reduction to ammonium (DNRA) is a process that converts nitrate to nitrite and then to ammonium.

Sourdough bread consumption has been associated with improved glucose and appetite regulation thanks to the presence of organic acids produced during fermentation of the flour-water mixture. We investigated the effects of whole meal sourdough bread (WSB) rich in lactic acid on energy intake, satiety, gastric emptying, glucose, and C-peptide response compared to whole meal yeast bread (WYB). Forty-four normal-weight participants (age: 30 ± 10 y; BMI: 23 ± 2 kg/m) participated in this double-blind, randomized cross-over trial, consisting of two study visits separated by one week.

Optical edge detection is a crucial optical analog computing method in fundamental artificial intelligence, machine vision, and image recognition, owing to its advantages of parallel processing, high computing speed, and low energy consumption. Field-of-view-tunable edge detection is particularly significant for detecting a broader range of objects, enhancing both practicality and flexibility. In this work, a novel approach-adaptive optical spatial differentiation is proposed for field-of-view-tunable edge detection.
