Summary: Photodynamic therapy (PDT) is an alternative method for treating cancer, with certain porphyrin derivatives showing higher efficiency than traditional drugs. In MCF-7 cells, cationic porphyrin 3 was found to be an effective photosensitizer. The study also revealed that cell death induced by the photodynamic process is caused by autophagic flux and necrosis.

Summary: Photodynamic Therapy (PDT) is a well-known alternative cancer treatment that relies on light activation of a photosensitizer in the presence of oxygen to induce cytotoxic effects in cancer cells. Proper light delivery and the selection of an appropriate photosensitizer are crucial for the effectiveness of PDT in treating cancer.

Summary: Ruthenium(II)-based coordination complexes have great potential as photosensitizers for photodynamic therapy. The modular architectures of these complexes allow for tuning of various properties such as cellular uptake, subcellular targeting, solubility, and light absorption. Many studies focus on systematic variation of ligands to investigate their impact on photophysical and photobiological performance. However, comparisons between Ru(II)-based PSs and other generations of PSs are scarce. Nonetheless, quantitative models based on PDT dose metrics are available for qualitative comparisons. This review summarizes the relevant studies on Ru(II)-containing PSs and their potential efficacy.

Summary: Due to the change in operation mode of the DESY II test beam facility, the existing beam telescope built with Mimosa26 chips is unable to meet the requirements of the increased beam particle rate. This article presents a new beam telescope built with ALice Pixel Detector (ALPIDE) chips, originally designed for the ALICE upgrade. The use of gigabit Ethernet in the high-speed transceiver of Kintex FPGA allows individual data acquisition and control of each ALPIDE chip, enhancing beam utilization and reducing track reconstruction difficulty.

Summary: In this study, a one-dimensional convolutional neural network (1D-CNN) is utilized to discriminate between neutrons and gamma rays detected by the Cs2LiYCl6: Ce3+(CLYC) crystal. Three different optimizers are used to train the CNN and the RMSProp optimizer yields the best performance. The CNN achieves an accuracy of 99.395% for the AmBe source, with false alarm rates (FARs) of only 0.003% and 0.020% for the gamma sources 137Cs and 22Na, respectively.

Summary: The Ramachandran plot is an important tool in biochemistry for visualizing the secondary structures of protein residues. This study used two different approaches, bioinformatics and molecular dynamics, to generate the plot. The analysis of the plot revealed that electrostatic interaction is the main contributor to the formation of secondary structures, while steric and exchange-correlation contributions play minor roles. These findings provide a deeper understanding of the nature and origin of secondary structure propensities from the Ramachandran plot.

Summary: This article presents a single-core broadband voltage-controlled oscillator (VCO) with a dual-mode variable inductor (VID). By using a magnetically coupled LC network with two independent switched-capacitor arrays, the VCO improves the frequency tuning range (FTR) by employing the wide inductance reconfigurable range of the X-type mode. The VCO also utilizes the low-quality factor (Q) degradation characteristic of the L-type mode for tuning bands calibration (TBC). The designed and fabricated VCO demonstrates low power dissipation and small die area in 65-nm CMOS technology.

Summary: Designing efficient and selective catalysts for carbon dioxide reduction is an active area of research in homogeneous catalysis. In this study, the catalytic activity of a newly reported Mn(I)-PNP-pincer catalyst with an embedded aromatic ring is investigated. The study systematically examines the catalyst's capability to yield different products and explores the importance of ligand aromaticity and steric effects on metal-ligand cooperativity. The reactivity of the catalyst is probed using conceptual density functional theory and an information-theoretic approach, leading to a novel partitioning of the reaction coordinate into three relevant regions. The results demonstrate that different properties govern the reactivity in these different regions, such as steric effects, electrophilicity/nucleophilicity, or aromaticity. The methodology and analytical tools employed in this study have the potential to be generalized and extended to other catalytic systems, offering insights towards designing improved catalysts.

Summary: We propose an electronically controlled optofluidic zoom imaging system combined with deep learning, which achieves a large continuous zoom change and a high-resolution image. The system consists of an optofluidic zoom objective and an image-processing module, and has a focal length range from 4.0 mm to 31.3 mm. Aberrations can be dynamically corrected by six electrowetting liquid lenses in the focal length range of 9.4 mm to 18.8 mm, while in the focal length range of 4.0-9.4 mm and 18.8-31.3 mm, deep learning is used to improve the image quality. The system has a zoom ratio of 7.8x and a maximum field of view of about 29 degrees, with potential applications in camera, telescope, and more.

Summary: Due to its noninvasiveness, high resolution, and high sensitivity, photoacoustic imaging has rapidly developed in biomedicine. However, research on dermatosis detection using photoacoustic imaging is still lacking. This study models the skin as a multilayer planar medium and derives an analytical expression for the photoacoustic signal of multilayer skin tissue. The study also considers the influence of the number of skin layers on the photoacoustic signal, providing a comprehensive understanding of photoacoustic mechanisms in dermatosis tissues.

Summary: Considerable research interest has been observed in recent literature regarding the development and applications of information-theoretic approach (ITA) quantities in density functional theory. These ITA quantities are explicit density functionals with continuous and well-behaved local distributions in real space. By systematically analyzing the topological behavior of four representative ITA quantities, namely Shannon entropy, two forms of Fisher information, and relative Shannon entropy, our work further develops ITA. The topological analyses for 103 molecular systems provide new insights into bonding interactions and physiochemical properties, such as electrophilicity, nucleophilicity, acidity, and aromaticity. Comparisons with results from other functions demonstrate the potential of our results as a methodological approach and practical tool for elucidating chemical bonding and reactivity propensity.

Summary: In this study, we demonstrate an efficient and accurate method for predicting the molecular response properties of condensed-phase systems under periodic boundary conditions. By combining the GEBF and ITA approaches, we establish linear relations between small subsystems and larger subsystems, allowing for the direct prediction of polarizabilities from the molecular wavefunction via ITA quantities. The proposed PBC-GEBF-ITA protocol shows good efficiency and transferability for periodic systems with hundreds of atoms in a unit cell.

Summary: We propose an efficient method to calculate the electrostatic component of solvation free energy using the two-point Pade approximation. This method only requires two simulations to determine the Pade approximant and compute the corresponding free energy contribution, making it useful for applications where accurate but computationally expensive energy functions like quantum mechanics are used. The method accurately predicts the electrostatic solvation free energy for both neutral and charged species, as demonstrated by applications to several model systems.

Summary: Understanding cooperativity and frustration is crucial for studying biological processes. This study evaluates the performance of different force fields in capturing cooperativity in neutral and charged molecular clusters. The results show that polarizable and nonpolarizable force fields qualitatively reproduce the relative cooperativity observed, but only the polarizable force field can describe absolute cooperativity.

Summary: Using density-based quantities to predict molecular reactivity is of interest in density functional theory, and recent developments in information-theoretic approach have represented this trend. In this contribution, a new representation of ITA quantities is introduced by approximating their partial derivatives with respect to the number of total electrons in a finite difference approximation. This work not only expands the theoretical framework of ITA but also provides new perspectives in dealing with molecular processes and chemical reactivity.
