Solid-SSolid-State Welding Methods
With the continuous improvement of lightweight requirements, the preparation of Mg/Al composite structures by welding is in urgent demand and has broad prospective applications in the industrial field. However, it is easy to form a large number of brittle intermetallic compounds when welding Mg/Al dissimilar alloys, and it is difficult to obtain high-quality welded joints. The solid-state welding method has the characteristics of low energy input and high efficiency, which can inhibit the formation of brittle intermetallic compounds and help to solve the problem of the poor strength of welded joints using Mg/Al dissimilar alloys in engineering applications.

Detection of Anomalies Using Acoustic Emission When Welding
Welding inspection is a critical process that can be severely time-consuming, resulting in productivity delays, especially when destructive or invasive processes are required. With non-destructive approaches, the actual service part can be inspected in both a speedy and non-invasive manner. A multi-spectral approach is used to give more confidence and information related to the anomaly of interest. This system is very portable and essentially could be used in most joining setup situations.

Cooling Load of Radiant Systems
The cooling load of systems refers to the heat removed from a room to the outside environment and adjacent rooms, which is based on some parameters such as zone climate data, location, usage, and so on. The cooling capacity of a radiant system represents the amount of cooling required at a specific moment to keep a stable room temperature. It is a basic parameter of radiant systems and an important reference for system design and operation. In addition, The changes of surface heat transfer coefficient also cause changes of cooling load and cooling capacity of the radiant system. Based on above background, current situation of researchers' studies on the cooling load is summarized, cooling capacity and surface heat transfer coefficient of radiant systems.

Earned Value for Construction Project Management Performance Improvement
Proper planning and management of construction projects have long been regarded as a necessity. The ability to make sound decisions and solve problems using appropriate performance reports related to the project implementation process are the two most key factors in controlling the performance of construction project management. It is important to identify and examine the influential factors on the performance improvement of construction project management with the value engineering approach based on earned value analysis for the successful evaluation of project performance.

Query-Driven Wireless Sensor Networks
In the context of query-driven wireless sensor networks (WSNs), a unique scenario arises where sensor nodes are solicited by a base station, also known as a sink, based on specific areas of interest (AoIs). Upon receiving a query, designated sensor nodes are tasked with transmitting their data to the sink.

Biopolymers and Bioprinting for Dental Tissue Engineering
Dental tissues are composed of multiple tissues with complex organization, such as dentin, gingiva, periodontal ligament, and alveolar bone. These tissues have different mechanical and biological properties that are essential for their functions. Therefore, dental diseases and injuries pose significant challenges for restorative dentistry, as they require innovative strategies to regenerate damaged or missing dental tissues. Biomimetic bioconstructs that can effectively integrate with native tissues and restore their functionalities are desirable for dental tissue regeneration.

Approaches to Quantifying Carbon Emissions with Human Deaths
When attempting to quantify future harms caused by carbon emissions and to set appropriate energy policies, it has been argued that the most important metric is the number of human deaths caused by climate change. Several studies have attempted to overcome the uncertainties associated with such forecasting.

Smart Materials for Green(er) Cities
The transition to sustainable or green(er) cities requires the development and implementation of many innovative technologies. It is vital to ensure that these technologies are themselves as sustainable and green as possible. In this context, smart materials offer excellent prospects for application. They are capable of performing a number of tasks (e.g., repair, opening/closing, temperature measurement, storage and release of thermal energy) without embedded electronics or power supplies.
