Summary: This article reviews the importance of infrared thermography in evaluating the thermal response and health status of wildlife species. Due to the different characteristics of wildlife species, thermal windows have not been established yet, so precise application is required for different animal species. The application of infrared thermography in zoos and conservation centers can help determine and monitor habitat designs to meet the specific needs of animals.

Summary: In laser-spot step-heating thermography, a laser beam is focused on the sample surface while the infrared video camera monitors the surface temperature rise. By analyzing the temperature profile at different time points after turning on the laser beam, the in-plane thermal diffusivity can be determined. This study shows that in thermal insulators, heat conduction to the surrounding gas, usually neglected in these experiments, plays a significant role in determining both thermal diffusivity and conductivity simultaneously.

Summary: This study found that body-surface thermal inhomogeneity could accurately assess the severity of critically ill patients at risk of hypoperfusion, especially through calculating the SD and LTAR parameters. These thermal parameters were correlated with blood pressure, lactate levels, and capillary refill time in patients. The AUROC of a combined prediction incorporating three thermal inhomogeneity parameters was considerably higher at 0.866.

Summary: The technique of thermal wave radar or pulse compression thermography, which utilizes a broadband modulated excitation signal and its cross-correlation with the thermal response, is widely used in active infrared thermography for defect characterization. However, the distortion of the thermal response due to heat diffusion affects the efficiency of cross-correlation analysis, especially for deep defects or materials with different thermal diffusivity. To overcome this issue, diffusion-compensated correlation analysis (DCCA) thermal signal is proposed, using a frequency-modulated sweep signal as an excitation waveform. DCCA can accurately analyze the thermal response in the presence of measurement noise, and can directly map the corresponding depth or diffusivity based on a library of template thermal responses. The performance of DCCA is analytically substantiated and verified through simulations and experiments on carbon fiber reinforced polymer plates, showing its superiority over thermal wave radar. The technique has potential for thermographic inspection of materials with artificial defects.

Summary: Local inversion symmetry breaking in centrosymmetric materials can lead to large spin polarization of the electronic band structure in separate sectors of the unit cell. The authors reveal such hidden spin polarization in ZrSiTe using spin and angle resolved photoemission spectroscopy in combination with ab initio band structure calculations. This study also highlights the complex evolution of spin polarization near the surface in the bulk states, emphasizing the intertwined nature of surface and bulk effects.

Summary: A novel long-lived metastable skyrmion phase has been discovered in the multiferroic insulator Cu2OSeO3 using Lorentz transmission electron microscopy. This phase, referred to as a hidden phase, can be accessed by exciting the sample with near-infrared femtosecond laser pulses. The magnetoelastic effect is identified as the most likely mechanism for the photocreation of this phase.

Summary: This study investigates the role of anisotropic exchange interaction (AEI) in the formation of tilted conical and disordered skyrmion states in the chiral magnet Cu2OSeO3. Using muon scattering and temperature dependence measurements, it is found that the AEI continuously increases below 50 K, leading to a 10% variation in the conical spiral pitch. These findings contribute to the understanding and design of various spiral states in chiral magnets.

Summary: The synthesis and X-ray structural study of a new family of compounds, Ba4Fe4ClO9.5-x, with tunable structural modulation is reported. The structure framework consists of Ba2Fe4O9.5-x composition and features open hexagonal channels along the c-axis filled with linear [Ba-Cl-Ba] triplets. The modulation of the crystal structure arises from the distribution of oxygen atoms in the framework and the arrangement of [Ba-Cl-Ba] triplets filling the channels.

Summary: The crystal structure of Ba-5(IO6)(2), pentabarium bis(orthoperiodate), was re-investigated at room temperature based on single-crystal X-ray diffraction data, with an improved precision of structural parameters achieved. Low-temperature measurements allowed the study of crystal structure evolution down to 80 K, showing no evidence of structural transition but revealing an inhomogeneous lattice contraction along different crystallographic axes. The interatomic distances between different Ba atoms drastically reduce with decreasing temperature, leading to a closer packing around the IO6 octahedra, which remain largely unaffected.
