Hybrid Convolutional Neural Network–Bidirectional Long Short-Term Memory
Recognition of lying is a more complex cognitive process than truth-telling because of the presence of involuntary cognitive cues that are useful to lie recognition. Researchers have proposed different approaches in the literature to solve the problem of lie recognition from either handcrafted and/or automatic lie features during court trials and police interrogations.

Characteristics of Battery Energy Storage Systems
With increasing concerns about climate change, there is a transition from high-carbon-emitting fuels to green energy resources in various applications including household, commercial, transportation, and electric grid applications. Even though renewable energy resources are receiving traction for being carbon-neutral, their availability is intermittent. To address this issue to achieve extensive application, the integration of energy storage systems in conjunction with these resources is becoming a recommended practice. Additionally, in the transportation sector, the increased demand for electric vehicles (EVs) requires the development of energy storage systems that can deliver energy for rigorous driving cycles, with lithium-ion-based batteries emerging as the superior choice for energy storage due to their high power and energy densities, length of their life cycle, low self-discharge rates, and reasonable cost. As a result, battery energy storage systems (BESSs) are becoming a primary energy storage system.

Algorithms in Tomography and Related Inverse Problems
In the ever-evolving landscape of tomographic imaging algorithms, a diverse array of themes shaping the field’s progress. It encompasses foundational principles, special innovative approaches, tomographic implementation algorithms, and applications of tomography in medicine, natural sciences, remote sensing, and seismology. This choice is to show off the diversity of tomographic applications and simultaneously the new trends in tomography. Accordingly, the evaluation of backprojection methods for breast tomographic reconstruction is highlighted. After that, multi-slice fusion takes center stage, promising real-time insights into dynamic processes and advanced diagnosis. Computational efficiency, especially in methods for accelerating tomographic reconstruction algorithms on commodity PC graphics hardware, is also presented. In geophysics, a deep learning-based approach to ground-penetrating radar (GPR) data inversion propels us into the future of geological and environmental sciences.

Domain Adaptive Semantic Segmentation of Remote Sensing Images
Semantic segmentation techniques for remote sensing images (RSIs) have been widely developed and applied. When a large change occurs in the target scenes, model performance drops significantly. Therefore, unsupervised domain adaptation (UDA) for semantic segmentation is proposed to alleviate the reliance on expensive per-pixel densely labeled data.

Door-Opening Drones
Doorknob accessories, wheelchair-mounted door-opening accessories, door-opening robots, and door-opening drones—were used to group the various technologies for manually opening doors. Drones are unmanned aerial vehicles (UAVs) with a wide range of applications, including product delivery, asset inspection, search and rescue, law enforcement and military services, disaster management, and emergency medical services. Drones are emerging as safe alternatives to humans in applications involving inaccessible environments or dangerous scenarios. In cases of medical emergencies, when a person is stuck in remote locations and an ambulance is unable to reach a patient in time, medical drones are being used for emergency medical services. Door-opening drones are unmanned aerial vehicles (UAVs) equipped with the capability to open doors.
