Physical and chemical characterization

The Co-N-rGO was synthesized using a previously established and reproducible microwave assisted method, as reported in our earlier work (refs. ^25,45,46) and described in detail in the Supporting Information….

We now describe the numerical model used to simulate QZD for a two-proton system. Our goal is to study the effect of frequent position measurements on the evolution of the wavefunction and estimate the conditions required for spatial…

Vortex line profiles: qualitative features

In a realistic scenario, the Crow instability may be triggered in a trapped Bose-Einstein condensate when the trapping potential landscape is locally inhomogeneous in the vicinity of a pair of…

First principle calculations of electron and phonon properties of Sb_xSe_y films

The calculated dielectric permittivities ε_∞ (electronic contribution) and ε_ion (ionic contribution) of Sb₂Se₃ crystal (Table 2) are in acceptable agreement with…

As shown in Fig. 1a,b, the refractive index and absorption coefficient exhibit frequency-dependent variations that distinguish normal and cancerous oral cells in the THz range. Both cell types display a sharp decline in refractive index as…

We investigate the critical fluctuations in Fe₃GeTe₂ (hereafter abbreviated as FGT), a van der Waals magnet exhibiting a paramagnetic-ferromagnetic phase transition. FGT is an exfoliable magnet that retains robust ferromagnetism with strong…

Experimental results

Figure 1(a) shows temperature dependent magnetization (M) of \(\hbox {Mn}_3\)GaC measured at 0.1 T field during zero- field cooling (ZFC) and field cooled warming (FCW) modes. It shows a FM transition at \(T_{C} \sim\) 310 K….

As a paradigmatic example, we use a giant Kerr cavity^47,48,49, which reduces to a giant two-level atom as its nonlinearity U approaches infinity, to demonstrate the multiphoton chiral dynamics. But it can also be extended to other giant systems….

Our first study harnesses the fact that rewards in real-world competitions often have predefined cutoffs. For example, in many sports, only the first three finishers are awarded a medal (i.e., the podium cutoff), creating a categorical difference…

Dataset

In this paper, multiple public datasets were selected for training, validation, and testing the model to ensure the diversity and generalization ability of style transfer.

First, we selected 100,000 images from the COCO dataset as content…
