We propose a floating depth and viewing angle-enhanced integral imaging (InIm) display system based on a transmissive mirror device (TMD). The system consists of a 2D display, a micro-lens array (MLA), and a TMD. The light emitted by the proposed InIm display system is reconstructed into a floating 3D image by the TMD, and the floating 3D image has a greater floating depth than the conventional InIm display without sacrificing resolution. The issue of mutual restriction between the floating depth and resolution of the 3D image is solved. The positions of the MLA and the 2D display are reversed through the TMD imaging, which results in an improved viewing range and an improved viewing angle of the floating 3D images. The system expands the floating depth and viewing angle simultaneously without sacrificing resolution. The experimental results prove the feasibility of the proposed system.

An in-depth understanding of carbon dynamics and ecosystem productivity is essential for conservation and management of different ecosystems. Ecosystem dynamics and carbon budget are assessed by estimating net ecosystem production (NEP) across different global ecosystems. An ecological productivity assessment of forest and floating meadow ecosystems in Keibul Lamjao National Park (KLNP), Manipur, North East India, was conducted using the multi-criteria decision-making process namely, gray relational analysis (GRA).

Methods: From the elevation of the anterior cornea and the refractive error of the eye, the target cornea can be calculated and the difference between actual and target cornea corresponds to the tissue to be removed. In this approach, it is further possible to preset the ablation depth at one (Model 1) or two (Models 2 and 3) particular locations.
Article Synopsis
- The Southern Ocean features dynamic mesoscale eddies that significantly influence global biogeochemical cycles, yet their overall effects on biogeochemistry have not been fully explored.
- Research aligns these eddies with data from biogeochemical Argo floats, revealing that anticyclonic eddies (AEs) lower dissolved inorganic carbon (DIC) and nitrate, while cyclonic eddies (CEs) increase these concentrations; dissolved oxygen also varies significantly between the two types of eddies.
- AEs and CEs play a role in the Southern Ocean's carbon uptake, with AEs contributing 0.01 Pg C while CEs offset this contribution by the same amount, highlighting the need to consider eddy effects in climate models

Oceanic tidal constituents and depth-integrated electrical conductivity (ocean conductivity content, or OCC) extracted from electromagnetic (EM) field data are known to have a strong potential for monitoring ocean heat content, which reflects the Earth's energy imbalance. In comparison to ocean tide models, realistic ocean general circulation models have a greater need to be baroclinic; therefore, both OCC and depth-integrated conductivity-weighted velocity ([Formula: see text]) data are required to calculate the ocean circulation-induced magnetic field (OCIMF). Owing to a lack of [Formula: see text] observations, we calculate the OCIMF using an ocean state estimate.

Article Synopsis
- Rivers are key pathways for transporting plastic litter to oceans and may also serve as sinks for plastics.
- The study focused on understanding the vertical distribution of macro- and mesoplastics in the Rhine and its branches using various sampling methods.
- Findings revealed that hard plastics are more commonly found at the river surface, while soft plastics are concentrated near the bottom, with specific ratios indicating how plastic concentrations vary with depth in the water column.
