36+ min ago   (271+ words) This work presents a conditional deep convolutional generative adversarial network (CDCGAN) for the inverse design of high-absorptance periodic metasurfaces (MSs) with different geometries. The conditioning mechanism encodes geometric and spectral parameters. A key innovation is the inclusion of unit cells…...

22+ hour, 56+ min ago   (546+ words) Lavandula × intermedia (lavandin) is among the most cultivated Lavandula species, valued for its high essential oil yield and broad applications across different industries. Although it has traditionally been regarded as inferior to true lavender (Lavandula angustifolia), particularly within the field…...

2+ day, 18+ hour ago   (389+ words) This study develops an analytical–evolutionary framework for optimizing the dynamic efficiency of bidirectional porous functionally graded beams. Touratier’s higher-order shear deformation theory is coupled with a real-coded genetic algorithm. The material-gradation indices in the thickness and width directions, the…...

3+ day, 17+ hour ago   (719+ words) Pelargonium graveolens and Pelargonium zonale are promising sources of natural antioxidants and other bioactive compounds that may find future use in topical cosmetic preparations. The aim of our study was to investigate the antioxidant properties and chemical composition of extracts…...

3+ day, 17+ hour ago   (436+ words) Folate-mediated one-carbon metabolism supports nucleotide biosynthesis, methylation reactions, and redox homeostasis, and the mitochondrial enzyme MTHFD2 has emerged as a cancer-associated metabolic target. However, the development of MTHFD2-preferential inhibitors remains challenging because MTHFD2 is structurally and functionally related to other folate-metabolism enzymes,…...

3+ day, 21+ hour ago   (14+ words) Computational chemistry has become an essential bridge between microscopic theory and measurable chemical behaviour [...]...

4+ day, 14+ hour ago   (423+ words) Yeast surface display (YSD) is a powerful tool for protein engineering, yet its broader application is often limited by suboptimal display efficiency. To address this, we systematically investigated the combinatorial effects of three key genetic determinants—promoter strength, anchoring protein…...

4+ day, 15+ hour ago   (464+ words) Mueller-matrix spectroscopic ellipsometry (MMSE) enables accurate characterization of nanostructures; however, structural-parameter retrieval remains challenging because of the high computational cost of rigorous coupled-wave analysis (RCWA), element-dependent prediction errors in the forward surrogate model, and instability caused by measurement noise. In…...

4+ day, 19+ hour ago   (271+ words) Numerical dispersion limits the accuracy of finite-difference elastic-wave modeling, particularly when relatively short spatial stencils are used. This study evaluates staggered-grid spatial-derivative coefficients obtained using a constrained simulated-annealing procedure and compares their spectral and numerical behavior primarily with Taylor-expansion coefficients…...

4+ day, 19+ hour ago   (310+ words) A broadband magnetically tunable reflective metasurface based on magnetized graphene is presented for terahertz cross-polarization conversion. The metasurface adopts a three-layer stacked configuration consisting of a patterned graphene resonator, a dielectric spacer, and a metallic ground plane. Under perpendicular magnetic…...
