Accurately identifying corresponded landmarks from a population of shape instances is the major challenge in con-

The present data can be useful for screening pitching technique to prevent shoulder pain and injury with motion capture assessment.

In this study, we succeeded in synthesizing new antiperovskite phosphides MPd 3 P (M = Ca, Sr, Ba) and discovered the appearance of a superconducting phase (0.17 ≤ x ≤ 0.55) in a solid solution (Ca 1-x Sr x )Pd 3 P. Three perovskite-related crystal structures were identified in (Ca 1-x Sr x )Pd 3 P and a phase diagram was built on the basis of experimental results. The first phase transition from centrosymmetric (Pnma) to non-centrosymmetric orthorhombic (Aba2) occurred in CaPd 3 P near room temperature. The phase transition temperature decreased as Ca 2+ was replaced with a largersized isovalent Sr 2+ . Bulk superconductivity at a critical temperature (T c ) of approximately 3.5 K was observed in a range of x = 0.17-0.55; this was associated with the centrosymmetric orthorhombic phase. Thereafter, a non-centrosymmetric tetragonal phase (I4 1 md) remained stable for 0.6 ≤ x ≤ 1.0, and superconductivity was significantly suppressed as samples with x = 0.75 and 1.0 showed T c values as low as 0.32 K and 57 mK, respectively. For further substitution with a larger-sized isovalent Ba 2+ , namely (Sr 1-y Ba y )Pd 3 P, the tetragonal phase continued throughout the composition range. BaPd 3 P no longer showed superconductivity down to 20 mK. Since the inversion symmetry of structure and superconductivity can be precisely controlled in (Ca 1x Sr x )Pd 3 P, this material may offer a unique opportunity to study the relationship between inversion symmetry and superconductivity.

Calcium is a vital constituent in multilayered cuprate superconductors with critical temperatures (Tc) above 100 K, because it plays a key role in separating CuO2 planes. Here, we demonstrate the synthesis of calcium-free double-layered cuprates: Sr2SrCu2O4(X,O)2(X = F, Cl, and Br) and M(Sr,Ba)2SrCu2Oy(M = Hg/Re, Tl, and B/C), where strontium exists between the CuO2 planes. Oxyfluoride and mercury-based materials show a Tc of 107 K and 110 K, respectively, which are high compared to existing calcium-free cuprates. These findings indicate Tc greater than 100 K can be realized by replacing both barium and calcium, which have been indispensable in conventional multilayered cuprates, with strontium. Furthermore, the non-toxicity of Sr2SrCu2O4F2 and (B,C)Sr2SrCu2Oy simplifies the synthesis process and ensures their safety in potential applications. We also perform a comparison of the characteristic structural parameters between the calcium-free and calcium-containing cuprates considering the number of CuO2 planes.
