AbstractParkinson’s disease (PD) exhibits heterogeneity in terms of symptoms and prognosis, likely due to diverse neuroanatomical alterations. This study employs a contrastive deep learning approach to analyze Magnetic Resonance Imaging (MRI) data from 932 PD patients and 366 controls, aiming to disentangle PD-specific neuroanatomical alterations.

AbstractExplosive mass ejections triggered by magnetic activities are common on our Sun and other stars in the Universe. However, there is a lack of evidence for such explosive phenomena in magnetized or partially magnetized planets with atmospheres. Here we present direct evidence for explosive mass ejections from the Martian ionosphere, resulting from magnetic reconnections between strong crustal field regions with open magnetic fields.

AbstractQuasi-continuous wave (QCW) laser has a very broad application in the industrial field, especially in additive manufacturing, surface treatment, laser cutting, laser cleaning, and laser drilling. Compared with the unidirectional fiber laser, the bidirectional output can be achieved two ports high power output with only one resonator, which can greatly reduce the industrial cost. However, there are few researches on QCW fiber lasers with bidirectional output.

1 INTRODUCTION The threat posed by pathogenic microorganisms to humans has increased as a result of new technologies like allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the use of immunosuppressive drugs, which have increased the prevalence of bacteria that are resistant to antibiotics and the number of immunocompromised people.1, 2 The gastrointestinal tract, which is regarded as the “second genome of humans,” has the biggest microbial population and is thought to include...
