Spatial ability is one of the essential abilities to be mastered by students, especially in geometry. There is not much research, especially in Indonesian, that examines students' spatial abilities and their relation to ...

Optical materials with nearly zero refractive indices have driven emerging applications ranging from geometry-invariant optical tunneling, nonlinear optics, optical cloaking to thermal emission manipulation. In conventio...

Self-affine property of a modified multifractal Cantor geometry is exploited to design frequency selective surfaces (FSS) with multiband response. The main advantage of the proposed structure is to design multiband FSS w...

Reliable trajectory similarity estimation underpins applications such as map matching, mobility anomaly detection, and travel behavior analysis. However, traditional distance-based methods are computationally expensive a...

One of the cognitive skills that students must have is problem-solving ability. Therefore, a standardized test is needed to measure this ability. However, until now, the tests used to measure mathematical problem-solving...

BackgroundLeft ventricular (LV) geometric remodeling is a key pathophysiological feature in heart failure with preserved ejection fraction (HFpEF), yet its prognostic implications among patients with concomitant atrial f...

Abstract This paper describes the development of a double-sided band-pass frequency selective surface based on Matryoshka geometry, preserving features such as miniaturization, multiband operation and stability of polari...

Key Points. We evaluated the association between the four categories of left ventricular geometry and all-cause mortality in patients undergoing hemodialysis. Concentric hypertrophy was the most prevalent, followed by co...

We explore how the quantum geometric properties of the Bloch wave function, characterized by the Hilbert-Schmidt quantum distance, impact magnetic phases in solid-state systems. To this end, we investigate the spin susce...

In this paper, we aim to establish several properties and notions for interpolative metric spaces and to introduce the idea of a Hausdorff interpolative metric space. Through the formulation of the key principles of Haus...

The geometry of the hydrogen bonds to the two carbonyl oxygens of the semiquinone QA- in the reaction center (RC) from the photosynthetic purple bacterium Rhodobacter sphaeroides R-26 were determined by fitting a spin Ha...

Humans around the world likely used thrusting spears during much of the Paleolithic period. A key development in spear evolution was the addition of a sharp stone tip. Here, we examined via controlled experiment whether ...

The necessity to reduce the weight of transport structures, such as cars and airplanes, has become more important due to gas emission regulations. In this regard, the use of hybrid structures made of steel and aluminum i...

The purpose of this research is to produce discovery learning based materials through ethnomathematics approaches on geometry transformation materials (valid, practical, and effective) and according to the needs of stude...

In this paper, we reconstruct Euclid’s theory of similar triangles, as developed in Book VI of the Elements, along with its 20th-century counterparts, formulated within the systems of Hilbert, Birkhoff, Borsuk and Szmi...
