Single-pixel imaging via data-driven and deep image prior dual networks.

Single-pixel imaging (SPI), especially when integrated with deep neural networks like deep image prior networks (DIP-Net) or data-driven networks (DD-Net), has gained considerable attention for its capability to generate high-quality reconstructed images, even in the presence of sub-sampling conditions. However, DIP-Net often requires thousands of iterations to achieve high-quality image reconstruction, and DD-Net performs optimally only when the target closely resembles the features present in its training set. To overcome these limitations, we propose a dual-network iterative optimization (SPI-DNIO) framework that combines the strengths of both DD-Net and DIP-Net.

Photon-counting single-pixel camera based on a fast spinning coding disk.

Spinning coding masks, recognized for their fast modulation rate and cost-effectiveness, are now often used in real-time single-pixel imaging (SPI). However, in the photon-counting regime, they encounter difficulties in synchronization between the coding mask patterns and the photon detector, unlike digital micromirror devices. To address this issue, we propose a scheme that assumes a constant disk rotation speed throughout each cycle and models photon detection as a non-homogeneous Poisson process (NHPP).

Solid pseudopapillary neoplasm: Report of a case of primary ovarian origin and review of the literature.

Background: Solid pseudopapillary neoplasms (SPNs) are uncommon tumors of low malignancy with a generally favorable prognosis, mostly originating from the pancreas. To date, 12 cases of SPNs with a primary ovarian origin (SPN-Os) have been reported globally, and their detailed characteristics have not been fully elucidated.

Case Description: We reported the 13th SPN-O case, which occurred in a 52-year-old woman with an 18.

[Effect of Helicobacter pylori infection on iron status among preschool children].

Objective: To explore the relationship between Helicobacter pylori (Hp) infection and iron status using serum ferritin (SF) as a marker for total iron and to identify the related factors of iron nutritional status among preschool children.

Methods: By cluster sampling, we recruited 475 preschool children aged 2 to 7 years. A structured questionnaire and diet form were sent to the parents of these children to obtain related information about the socioeconomic level and dietary intakes.

[Estimation of postmortal interval by measuring the amount of DNA in cells].

Although there are many methods to estimate the early postmortal interval, more attention has been paid to the research on measuring the amount of DNA in cells. This paper introduce several different measuring ways, law of variation and application situation of DNA in cells. In addition, the result evaluation of measuring methods and application prospect is given.
