Abstract The inverse problem analysis method provides an effective way for the structural parameter identification. However, uncertainties wildly exist in the practical engineering inverse problems. Due to the coupling o...

Deep learning offers a novel opportunity to achieve both high-quality and high-speed computer-generated holography (CGH). Current data-driven deep learning algorithms face the challenge that the labeled training datasets...

El concepto de calificación de métodos de regularización espectrales (MREs) para problemas inversos mal condicionados está fuertemente asociado con el orden de convergencia óptimo delerror de regularización (H. W. ...

Optical cryptanalysis is essential to the further investigation of more secure optical cryptosystems. Learning-based attack of optical encryption eliminates the need for the retrieval of random phase keys of optical encr...

In recent years there has been a growing interest in the study of sparse representation of signals. Using an overcomplete dictionary that contains prototype signal-atoms, signals are described by sparse linear combinatio...

Recent advances in inverse-design approaches for discovering optical structures based on desired functional characteristics have reshaped the landscape of nanophotonic structures, where most studies have focused on how l...

The optical properties of thin-film light emitting diodes (LEDs) are strongly dependent on their structures due to light interference inside the devices. However, the complexity of the design space grows exponentially wi...

Once light is coupled to a photonic chip, its efficient distribution in terms of power splitting throughout silicon photonic circuits is very crucial. We present two types of 1 × 4 power splitters with different splitti...

Nanophotonic devices manipulate light at sub-wavelength scales, enabling tasks such as light concentration, routing, and filtering. Designing these devices to achieve precise light–matter interactions using structural ...

Deep learning has become the dominant approach in artificial intelligence to solve complex data-driven problems. Originally applied almost exclusively in computer-science areas such as image analysis and nature language ...

Abstract The time-domain inverse technique based on the time-domain rotating equivalent source method has been proposed to localize and quantify rotating sound sources. However, this technique encounters two problems to ...

Abstract Background Functional Family Therapy (FFT) is a short‐term family‐based intervention for youth with behaviour problems. FFT has been widely implemented in the USA and other high‐income countries. It is oft...

The aim of this Campbell Systematic Review was to evaluate the effect of multi‐systemic therapy (MST) on adolescents with social, emotional, and behavioural problems based on the best available evidence. The effect is ...

Abstract Background Multisystemic Therapy® (MST®) is an intensive, home‐based intervention for families of youth with social, emotional, and behavioural problems. MST therapists engage family members in identifying a...

Metasurfaces are subwavelength-structured artificial media that can shape and localize electromagnetic waves in unique ways. The inverse design of these devices is a non-convex optimization problem in a high dimensional ...

The scattering matrix is the mathematical representation of the scattering characteristics of any scatterer. Nevertheless, except for scatterers with high symmetry like spheres or cylinders, the scattering matrix does no...

Metalenses have gained significant attention and have been widely utilized in optical systems for focusing and imaging, owing to their lightweight, high-integration, and exceptional-flexibility capabilities. Traditional ...

Abstract In this paper, a modified globally convergent self-scaling BFGS algorithm for solving convex unconstrained optimization problems was investigated in which it employs exact line search strategy and the inverse He...

Structural vibrations in Tip-Tilt modes usually affect the closed-loop performance of astronomically optical telescopes. In this paper, the state of art control methods-proportional integral (PI) control, linear quadrati...

Aggressiveness is associated to several problems in the child development, with evidences of inverse correlation with empathy that is seen as a possible inhibitor of such behaviors. Based in the referential of the Social...

In this study, the chronic renal failure patients undergoing hemodialysis (HD) or continuous ambulatory peritoneal dialysis (SAPD) therapy were compared in terms of aspects of disability, depression, anxiety with the inv...

Antisocial young people who have received cognitive behavioural therapy or other types of treatment in residential settings, do better than young people who have not been offered such treatment. Twelve months after leavi...
