Wavefront distortion in temporal focusing microscopy (TFM) results in a distorted temporal profile of the excitation pulses owing to spatio-temporal coupling. Since the pulse duration is dramatically changed in the excitation volume, it is difficult to correct the temporal profile for a thick sample. Here, we demonstrate adaptive optics (AO) correction in a thick sample. We apply structured illumination microscopy (SIM) to an AO correction in wide-field TFM to decrease the change in the pulse duration in the signal detection volume. The AO correction with SIM was very successful in a thick sample for which AO correction with TFM failed.

The well-known technique of microtomy, which is an essential cutting tool, was first developed for light and transmission electron microscope uses, but it is currently also utilized to prepare specimens for atomic force microscopy (AFM), ion microscopy using a focused ion beam (FIB), and scanning electron microscopy (SEM). Ultramicrotomy can only be used on soft substances and metals that are sufficiently ductile to be cut with a diamond knife. Before being sliced by a microtome, many soft materials must first go through numerous preparatory processes.

Background: Disturbances in lipid metabolism are usually associated with hyperlipidemia, which is commonly observed in donkeys with inappetence or anorexia. The diagnostic utility of ultrasound measurements of croup fat thickness (CFT) and relative liver echogenicity for lipomobilization in donkeys with fasting-induced hyperlipidemia was investigated. A prospective observational control study involving 25 donkeys was conducted, and the animals were randomly assigned to a fasting group (FG, n = 20) and a control group (CG, n = 5).

SnSe is a layered semiconductor with intrinsically low thermal conductivity, making it a promising candidate for thermoelectric and thermal management applications. However, detailed measurements of the intrinsic thermal conductivity of SnSe nanosheets grown by chemical vapor deposition (CVD) remain scarce. Here, monocrystalline SnSe nanosheets were synthesized by CVD, with systematic investigation of thickness-dependent in-plane thermal conductivity.

Accurate prediction of time-varying dynamic parameters during the milling process is a prerequisite for chatter-free cutting of thin-walled parts. In this paper, a matrix iterative prediction method based on weighted parameters is proposed for the time-varying structural modes during the milling of thin-walled blade structures. The thin-walled blade finite element model is established based on the 4-node plate element, and the time-varying dynamic parameters of the workpiece during the cutting process can be obtained by modifying the thickness of the nodes through the constructed mesh element finite element model It is not necessary to re-divide the mesh elements of the thin-walled parts at each cutting position, thus improving the calculation efficiency of the dynamic parameters of the workpiece.

Background: The purpose of the study is to evaluate the use of a magnetodynamic instrument (Magnetic Mallet, Metaergonomica, Turbigo, Milan, Italy) to perform a horizontal bone expansion in edentulous sites that need to be rehabilitated with a dental implant.
Methods: A sample of 15 patients, 11 men and 4 women, age between 39 and 78 years, was analyzed. A total of 18 conical-shaped implants with a diameter of 3.
