A novel computational integral imaging reconstruction (CIIR) method, utilizing elemental image blending, is introduced in this paper to eliminate the normalization process in CIIR. Uneven overlapping artifacts in CIIR are often tackled with the normalization procedure. Elemental image blending within CIIR obviates the need for normalization, thereby minimizing memory consumption and processing time in comparison to existing techniques. Using a theoretical framework, we analyzed the influence of elemental image blending on a CIIR method, employing windowing techniques. The resultant data demonstrated the proposed method's superiority over the standard CIIR method in terms of image quality metrics. Using both computer simulations and optical experiments, we also evaluated the proposed method. The standard CIIR method's image quality was outperformed by the proposed method, which also exhibited reduced memory usage and processing time, as demonstrated by the experimental results.

Accurate assessment of permittivity and loss tangent in low-loss materials is paramount for their crucial roles in ultra-large-scale integrated circuits and microwave devices. A novel strategy for precisely detecting the permittivity and loss tangent of low-loss materials, based on a cylindrical resonant cavity in the TE111 mode at X band frequencies (8-12 GHz), was developed in this research. Using electromagnetic field simulation of the cylindrical resonator, the permittivity is determined with precision by examining the influence of the coupling hole's alteration and sample size variation on the cutoff wavenumber value. An enhanced procedure for measuring the loss tangent across samples of differing thicknesses has been presented. The standard sample test results demonstrate this method's accuracy in measuring dielectric properties of smaller samples compared to the high-Q cylindrical cavity method.

Ships and aircraft commonly deploy underwater sensors in random patterns. This practice contributes to an uneven dispersion of nodes in the aquatic environment. As a result, energy consumption varies significantly across different sectors of the network, influenced by the fluctuating water currents. Furthermore, the underwater sensor network suffers from a hot zone issue. In response to the disparate energy demands within the network, a novel non-uniform clustering algorithm for energy equalization is presented. Taking into account the residual energy, node density, and redundant coverage of nodes, this algorithm strategically selects cluster heads, ensuring a more balanced distribution. Importantly, the chosen cluster heads' decision on cluster size aims to balance energy usage within the multi-hop routing network. The residual energy of cluster heads and the mobility of nodes are factored into real-time maintenance for each cluster within this process. Simulation outputs confirm the proposed algorithm's capacity to increase network duration and balance the consumption of energy; likewise, it sustains network coverage better than alternative algorithms.

We are reporting on the development of scintillating bolometers, the constituent lithium molybdate crystals of which incorporate molybdenum depleted into the double-active isotope 100Mo (Li2100deplMoO4). Utilizing 45-millimeter-sided Li2100deplMoO4 cubic samples, each weighing 0.28 kg, two specimens were employed. These samples were created via purification and crystallization procedures devised for double-search experiments using 100Mo-enriched Li2MoO4 crystals. The scintillation photons produced by Li2100deplMoO4 crystal scintillators were measured by utilizing bolometric Ge detectors. Measurements were made at the Canfranc Underground Laboratory (Spain), specifically within the CROSS cryogenic setup. Li2100deplMoO4 scintillating bolometers demonstrated exceptional spectrometric capabilities, achieving a 3-6 keV FWHM at 0.24-2.6 MeV. Their scintillation signals, while moderate (0.3-0.6 keV/MeV scintillation-to-heat energy ratio), varied based on light collection efficiency. Furthermore, their high radiopurity, evidenced by 228Th and 226Ra activities remaining below a few Bq/kg, matched leading low-temperature detectors utilizing Li2MoO4 with either natural or 100Mo-enriched molybdenum. The utility of Li2100deplMoO4 bolometers for rare-event search experiments is briefly evaluated.

Rapid determination of the shape of single aerosol particles was achieved through an experimental setup that amalgamated polarized light scattering and angle-resolved light scattering measurement techniques. Data analysis of light scattering experiments performed on oleic acid, rod-shaped silicon dioxide, and other particles with typical morphologies was conducted statistically. Employing partial least squares discriminant analysis (PLS-DA), the investigation explored the connection between particle geometry and the properties of scattered light. The scattered light from aerosol samples was analyzed based on particle size fractionation. A method for recognizing and classifying the form of individual aerosol particles was developed, building upon spectral data after non-linear processing and size-based grouping. The area under the receiver operating characteristic curve (AUC) was used as a criterion for assessment. The experimental data validates the proposed classification method's aptitude in differentiating between spherical, rod-shaped, and other non-spherical particles, yielding data crucial for atmospheric aerosol analysis, highlighting its practical value for traceability and exposure risk assessment.
