Advanced fractal two-scale method for 905 nm laser scattering calculation of water-covered asphalt pavement and coverage perception.

Sudden changes in pavement coverage can easily result in a vehicle's loss of control. Accurately characterizing laser scattering properties is essential for intelligent vehicle sensors like lidars to perceive pavement coverage information. In response to significant issues such as low computational efficiency, poor accuracy of existing scattering models, and the lack of methods for perceiving pavement water coverage information, this paper introduces an advanced laser scattering calculation method capable of describing water coverage conditions based on the fractal two-scale method (FTSM).

Gradient domain model-driven algorithm unfolding network for blind image deblurring.

Blind image deblurring remains a challenging ill-posed problem due to the simultaneous estimation of clear images and blur kernels. Recently, image deblurring methods that utilize algorithm unfolding techniques have made significant advancements. However, the classical image gradient prior, despite its effectiveness, remains an unexplored avenue in deep unfolding frameworks.

A review of factors affecting the soil microbial community structure in wetlands.

Microbial community in wetland soils is crucial for maintaining the stability of the wetland ecosystem. Nevertheless, the soil microbial community is sensitive to the environmental stress in wetlands. This leads to the possibility that the microbial community structure may be influenced by environmental factors.

This study aimed to investigate the initial post-release performance of cultured juveniles by examining their movement, spatial distribution, gut fullness, and gut microbiota in nature. In July 2022, a total of 20,000 juveniles, tagged with visible implant fluorescence (VIE), were released into Qilu Lake, a shallow lake in southwestern China.

Fractal two-scale method for calculating the laser scattering distribution of asphalt pavement.

The laser scattering characteristic of pavement is one of the important factors that affect the detection performance of optical sensors such as lidars. Because the wavelength of laser does not match the roughness of the asphalt pavement, the common analytical approximation model of electromagnetic scattering is not applicable in this case, so it is difficult to calculate the laser scattering distribution of the pavement accurately and effectively. According to the self-similarity of the asphalt pavement profile, a fractal two-scale method (FTSM) based on fractal structure is proposed in this paper.

Differences in nitrification and ammonium-oxidising prokaryotes in the process of wetland restoration.

Ammonia-oxidising archaea (AOA) and ammonia-oxidising bacteria (AOB) are ammonium oxidising prokaryotes that can drive soil nitrification in wetlands. During the restoration of wetlands, different types of land use soils (agricultural soil [AS], restored wetland soil [RS], and natural wetland soil [NWS]) are present. However, studies on the effects of changes in the types of land use in wetlands during restoration on nitrification and the community composition of AOA and AOB are still not well understood.

A Quantified Risk-Scoring System for the Recurrence of Meningiomas: Results From a Retrospective Study of 392 Patients.

This study aimed to identify the independent risk factors of recurrence in patients undergoing primary resection of meningioma and construct a scoring system for the prediction of the risk of postoperative recurrence.

The clinical, radiological, and pathological characteristics were evaluated, and the independent risk factors for recurrence were identified via receiver operating characteristic (ROC) curve and logistic analyses.

A novel regeneration method for deactivated commercial NH-SCR catalysts with promoted low-temperature activities.

A novel route is developed for regeneration of deactivated commercial NH-SCR catalysts, which includes an initial in situ construction of anatase TiO porous film, followed by loading of MnO, CeO, and Mn-Ce mixed oxides as active components. The regenerated catalysts present largely improved low-temperature denitrification performance due to the synergetic effect of MnO and CeO. The denitrification efficiency could reach a high value of 97% at 200 °C and 100% at 250 °C when the Ce-Mn mixed oxides are loaded at the optimized molar quantity ratio of 10:9 (Ce:Mn).

The quantitative real-time polymerase chain reaction results showed that the average abundance of nirS and nirK genes was notably affected by seasonal changes, increasing from 2.

In this paper, we derive an analytical solution of the maximum likelihood estimation for the Gaussian model as the probability density function (PDF) of the range estimator.

miR‑34a derived from mesenchymal stem cells stimulates senescence in glioma cells by inducing DNA damage.

Insights into the roles of microRNAs (miRNAs/miRs) in development and disease, particularly in cancer, have made miRNAs attractive tools and targets for novel therapeutic approaches in the treatment of glioma. miR‑34a, as a well‑known tumor suppressor miRNA, is closely related with cellular senescence. Mesenchymal stem cells (MSCs) are a major component of the tumor microenvironment and possess the ability to deliver exogenous miRs to glioma cells to exert anti‑tumor effects.

Research on the optimal optical attenuation in a laser radar using a Geiger-mode APD.

For a laser radar (LADAR) system using a Geiger-mode avalanche photodiode (GmAPD), attenuating echo and background noise simultaneously affect the original data output from the GmAPD and eventually affect detection performance. In this study, we established a model that applies to the GmAPD-based LADAR with optical attenuation and also applies to any typical single photon detector that has a dead time (e.g.

The splicing factor SPF45 (RBM17) is a well-known component of the spliceosome that is involved in alternative splicing. RBM17 is frequently overexpressed in many tumors and plays a crucial role in cancer progression and drug resistance. However, the role of RBM17 in the development of glioma has not been thoroughly elucidated to date.

Influence of fog on the signal to interference plus noise ratio of the imaging laser radar using a 16-element APD array.

This paper investigates the signal to interference plus noise ratio (SINR) performance of the imaging laser radar (ILR) system operating at a wavelength of 905 nm using an avalanche photodiode array under the fog condition. We analysis the glow image of the light source, which is formed by the laser spot irradiated on a standard Lambertian target. Based on the proposed theoretical model, we determine the interference due to the glow inter-channel crosstalk under different fog conditions for a targeted channel.

Our model has the advantage of fast computing speed and unifies multi-trigger, single-trigger, and zero-dead-time models.
