DNA is a promising storage medium, offering advantages in high density, long durability, and low maintenance cost. However, information recovery in DNA storage systems is challenged by errors arising during synthesis, amplification, and sequencing phases. A key challenge in decoding is sequence reconstruction, which involves recovering the original reference sequence from a set of noisy copies.

The utilization of resonant-unit-based metamaterials in beam control and compact stealth applications is inherently limited by the strong correlation between unit in-plane dimensions and reflection characteristics. Therefore, this study proposes a resonator-free metamaterial based on ferromagnetic dielectric that decouples the amplitude and phase by regulating interface interference, thereby achieving phase modulation independent of the in-plane dimensions of the FD units. With the introduction of a constant phase gradient and tuning of unit dimensions, reflected waves can be deflected or even converted into surface waves that propagate along the metamaterial interface.

Magnetic absorbers with high permeability have significant advantages in low-frequency and broadband electromagnetic wave (EMW) absorption. However, the insufficient magnetic loss and inherent high conductivity of existing magnetic absorbers limit the further expansion of EMW absorption bandwidth. Herein, the spinel (FeCoNiCrCu)O high-entropy oxides (HEO) are successfully constructed on the surface of FeCoNiCrCu high-entropy alloys (HEA) through low-temperature oxygen bath treatment.

Vaginitis is a common condition in women that is described medically as irritation and/or inflammation of the vagina; it poses a significant health risk for women, necessitating precise diagnostic methods. Presently, conventional techniques for examining vaginal discharge involve the use of wet mounts and gram staining to identify vaginal diseases. In this research, we utilized fluorescent staining, which enables distinct visualization of cellular and pathogenic components, each exhibiting unique color characteristics when exposed to the same light source.

This retrospective study included 311 patients who had increased nuchal translucency (NT ≥3 mm) or nuchal septations (NSs) during the first trimester from January 2018 to December 2020. These patients were divided into 3 groups: (1) patients with NT thickness between 3 and 5 mm and without NS (NT 3-5 mm group, n = 131), (2) patients with NT thickness >5 mm and without NS (NT >5 mm group, n = 105), and (3) patients with NS (NS group, n = 75). The incidence of abnormal pregnancy outcomes was 92.

Respiratory syncytial virus (RSV) is an enveloped, negative-sense, single-stranded RNA virus of the Orthopneumovirus  genus of the Pneumoviridae family in the order Mononegavirales. RSV can cause acute upper and lower respiratory tract infections, sometimes with extrapulmonary complications. The disease burden of RSV infection is enormous, mainly affecting infants and older adults aged 75 years or above.

The attention network test (ANT), developed based on the triple-network taxonomy by Posner and colleagues, has been widely used to examine the efficacy of alerting, orienting and executive control in clinical and developmental neuroscience studies. Recent research suggests the imperfect reliability of the behavioural ANT and its variants. However, the classical ANT fMRI task's test-retest reliability has received little attention.
