Abstract

This study presents an iterative adaptive compression model for high-resolution DPX-derived TIFF files used in cinematographic workflows and digital preservation. The model employs SSIM and PSNR metrics to dynamically adjust compression parameters across three configurations (C0, C1, C2), achieving storage reductions up to 83.4 % while maintaining high visual fidelity (SSIM > 0.95). Validation across three diverse productions - black and white classic, soft-palette drama, and complex action film - demonstrated the method's effectiveness in preserving critical visual elements while significantly reducing storage requirements. Professional evaluators reported 90% acceptance rate for the optimal C1 configuration, with artifacts remaining below perceptual threshold in critical areas. Comparative analysis with JPEG2000 and H.265 showed superior quality preservation at equivalent compression rates, particularly for high bit-depth content. While requiring additional computational overhead, the method's storage benefits and quality control capabilities make it suitable for professional workflows, with potential applications in medical imaging and cloud storage optimization.

Abstract

Introduction/Objective. STAT3 (signal transducers and activators of transcription) is involved in different physiological processes, including cell proliferation and survival. High expression of this protein is observed in various types of cancer. This study aimed to investigate the gene and protein expression of STAT3 in a series of odontogenic cysts and tumors to provide more information about their biological profile. Methods. The STAT3 gene expression at mRNA was quantified by real-time quantitative polymerase chain reaction (RT-qPCR) in 23 odontogenic keratocysts (OKCs) and seven ameloblastomas (AMs), and compared to the non-neoplastic oral mucosa. We also assessed the expression of STAT3 gene at protein levels, using immunohistochemistry, in 43 OKCs and 47 AMs. Results. STAT3 transcripts were found in 96.6% of the tumors studied; however, the gene was downregulated in OKC and AM compared to the non-neoplastic oral mucosa. The STAT3 gene expression at mRNA level was higher in sporadic OKC than in syndromic OKC (p = 0.04). There was no difference in STAT3 gene expression at mRNA level between OKCs and AMs (p = 0.88). Immunostaining of STAT3 revealed no significant difference between sporadic and syndrome OKC (p > 0.05), nor between conventional and unicystic AMs (p > 0.05). Ameloblastomas exhibited significantly higher STAT3 immunostaining than OKCs (p = 0.03). In OKC and AM, STAT3 immunostaining was predominantly cytoplasmic and no difference in the cellular localization of STAT3 was observed between these lesions (p = 0.58). Conclusion. Our findings showed low expression of STAT3 gene in OKCs and AMs in relation to nonneoplastic oral mucosa. However, higher STAT3 immunostaining was observed in AMs compared to OKCs.

25. Observation of parity-time symmetry breaking transitions in a dissipative Floquet system of ultracold atoms

Abstract

Open physical systems with balanced loss and gain, described by non-Hermitian parity-time ($\mathcal{PT}$) reflection symmetric Hamiltonians, exhibit a transition which could engenders modes that exponentially decay or grow with time and thus spontaneously breaks the $\mathcal{PT}$-symmetry. Such $\mathcal{PT}$-symmetry breaking transitions have attracted many interests because of their extraordinary behaviors and functionalities absent in closed systems. Here we report on the observation of $\mathcal{PT}$-symmetry breaking transitions by engineering time-periodic dissipation and coupling, which are realized through state-dependent atom loss in an optical dipole trap of ultracold $^6$Li atoms. Comparing with a single transition appearing for static dissipation, the time-periodic counterpart undergoes $\mathcal{PT}$-symmetry breaking and restoring transitions at vanishingly small dissipation strength in both single and multiphoton transition domains, revealing rich phase structures associated to a Floquet open system. The results enable ultracold atoms to be a versatile tool for studying $\mathcal{PT}$-symmetric quantum systems., Comment: 23 pages, 4 figures, 39 references

28. Parametric cooling of a degenerate Fermi gas in an optical trap

Abstract

We demonstrate a novel technique for cooling a degenerate Fermi gas in a crossed-beam optical dipole trap, where high-energy atoms can be selectively removed from the trap by modulating the stiffness of the trapping potential with anharmonic trapping frequencies. We measure the dependence of the cooling effect on the frequency and amplitude of the parametric modulations. It is found that the large anharmonicity along the axial trapping potential allows to generate a degenerate Fermi gas with anisotropic energy distribution, in which the cloud energy in the axial direction can be reduced to the ground state value.

Abstract

Recommendation of new varieties is supported by value for cultivation and use (Valor de Cultivo e Uso [VCU]) trials. For a more reliable recommendation, it is necessary to identify methodologies that make better use of the genotype‐by‐environment interaction (GEI). The methodology proposed by Dias et al. is an alternative to take advantage of the GEI; it considers concepts of Bayesian models and probability methods of adaptation and stability analysis in a single model, classifying the genotypes regarding possible success based on a defined selection intensity. Thus, the aim of the present study was to explore the use of Bayesian probabilistic method for the purpose of recommend common bean (Phaseolus vulgaris L.) varieties. To that end, we used grain yield data from 15 genotypes of common bean evaluated in 42 environments distributed over different crop seasons, years, and locations in regard to VCU trials conducted from 2016 to 2018. Under a predefined selection intensity of 30%, the genotypes with greater marginal probability of superior performance were G01, G14, G07, G11, and G02. The genotypes with greater marginal probability of superior stability were G06, G07, G04, G03, and G12. Considering the joint probability of superior performance and yield stability, the genotypes G07, G14, G01, G11, and G04 stand out. Therefore, the use of the Bayesian probabilistic method showed promise in recommendation of common bean varieties. Core Ideas: Reliable recommendations of common bean varieties can be obtained from probabilist Bayesian models.High‐performance and stable common bean varieties were identified for tropical conditions.Probability methods can minimize risk in decision‐making for broad and specific variety recommendation. Plain Language Summary: Recommendation of varieties is supported by multi‐environment trials (MET). In MET, in addition to genetic and environmental effects, there is an interaction between these (GEI). According to the study of Dias et al., the methodology to take advantage of the GEI is based in Bayesian probabilistic models. Thus, the aim of the present study was to explore the use of Bayesian probabilistic method proposed by Dias et al. for recommending common bean (Phaseolus vulgaris L.) varieties. To that end, we used grain yield data from 15 genotypes of common bean evaluated in 42 environments. Under a predefined selection intensity of 30%, the genotypes with greater joint probability of superior performance and yield stability were G07, G14, G01, G11 and G04. The use of the Bayesian probabilistic method showed promise in recommendation common bean varieties. [ABSTRACT FROM AUTHOR]

Abstract

This research presents a point‐of‐use (POU) water treatment technology utilizing metal/metallic surfaces based on Triply Periodic Minimal Surface (TPMS) structured filtration infills. Computational Fluid Dynamics modeling using Ansys CFX software is employed to analyze the behavior of Escherichia coli bacteria within a continuous liquid phase moving through the filtration infill, assess particle collision dynamics, and evaluate the efficiency of filtration, considering pressure drop as a fundamental factor in process energy consumption. TPMS infill meshes are coded in a Schwarz P shape using Python, and the Darcy‐Forchheimer equation is employed to determine the permeability and resistance loss coefficient of the infill geometry. The results indicate that the TPMS infill efficiently captures particles while introducing a negligible pressure drop into the system. It is found that a single 40 mm infill configuration is the most efficient, exhibiting a higher collision rate compared to the smaller 20 mm infill configuration and a lower pressure drop compared to the two 20 mm infill configurations in the series. Additionally, this study provides insights into the behavior of continuous fluid flow through TPMS infill in view of scaled‐up implementation, including the presence of recirculation zones that can be exploited to further enhance the collision rate of particles.
