Summary: A reliable Q-switched and mode-locked operation at the 1.5-mu m region has been achieved using copper nanoparticles (Cu NPs)-doped Indium Selenide (In2Se3) as a saturable absorber. Q-switched pulses with a pulse width of 2.54 mu s and a repetition rate of 122.60 kHz were generated at the operating wavelength of 1561.9 nm. A soliton with a pulse width of 3.59 ps and a peak power of 1.68 kW was generated when a 100 m single-mode fiber (SMF) was integrated into the laser cavity with Cu/In2Se3.

Summary: This paper examines the impact of network position on urban agglomeration economies (UAEs) using a high-speed rail (HSR) operation network model based on data from China from 2008 to 2019. The findings suggest that improvements to network position significantly enhance UAEs, particularly in national core cities. The impact on UAEs is realized before and after the opening of the HSR line, with investment agglomeration and expansions as the main mechanisms facilitating UAEs.

Summary: The synthesis of amorphous Li3BO3 was successfully conducted using induction thermal plasma, and the formation mechanism was systematically investigated. Various characterization techniques were employed to understand the morphology and chemical composition of the products. It was found that higher O2 and quenching gas flow rates resulted in a higher degree of amorphous Li3BO3, but also increased the possibility of by-product formation.

Summary: Limb autotomy and regeneration are specific adaptations of crustaceans in response to external stress and attacks, which make them a suitable model to investigate the mechanism of organ regeneration in invertebrates. The Hippo gene of Eriocheir sinensis (EsHPO) was identified, and the effects of Hippo signaling on limb regeneration were evaluated. The study found that Hippo signaling plays a key role during limb regeneration in E. sinensis by inducing ECM remodeling, as well as promoting the proliferation and repressing the apoptosis of blastema cells.

Summary: In this study, we investigated the role and mechanism of TXNIP in PCOS. TXNIP was found to be upregulated in the ovaries of PCOS mice and testosterone-treated granulosa cells. Knockdown of TXNIP attenuated GC injury, oxidative stress, inflammation, and NLRP3 inflammasome activation. Furthermore, knockdown of TXNIP ameliorated ovarian injury and inflammation in mice with DHEA-induced PCOS. These findings suggest that TXNIP is involved in GC inflammation by promoting NLRP3 inflammasome activation in PCOS.

Summary: Global climate change caused by carbon emissions has posed severe challenges to the sustainable development of the global economy. This study constructs a weighted and directed carbon emission network for the European Union (EU), analyzes the structural characteristics of the network using social network analysis, investigates the role of countries within the network using cluster analysis, and explores the impacts of network characteristics on carbon emissions through linear regression. The findings reveal the network structure of carbon emissions among EU countries, the roles played by different countries in the network, and the effects of network characteristics on carbon emissions. Based on these findings, policy suggestions for collaborative governance of EU carbon emission abatement are put forward.

Summary: This study aimed to predict potential hub genes in CD5+ DLBCL. CD5 high expression was correlated with IPI, LDH, and Ann Arbor stage, and CD5-DLBCL patients had longer overall survival. Three hub genes (VSTM2B, GRIA3, and CCND2) were screened, with CCND2 mainly involved in cell cycle regulation and JAK-STAT signaling pathways. CCND2 expression was correlated with CD5 and overexpression in CD5+ DLBCL patients had poor prognosis. CD5 and CCND2 double positive tumors should be stratified into specific subgroups of DLBCL with poor prognosis.

Summary: This study compared the Montreux definition and the Berlin definition in terms of the prevalence, mortality, and complications of neonatal acute respiratory distress syndrome (ARDS). The data of neonates with respiratory failure treated in a neonatal intensive care unit (NICU) between November 1, 2019, and December 31, 2021, were retrospectively analyzed. The prevalence and mortality of neonatal ARDS did not differ between the definitions. Key clinical outcomes, such as ventilation duration, NICU stay, and complication rates, were similar between the definitions, except for nitric oxide inhalation. The definitions identified additional patients not captured by the other definition, and the severity of neonatal ARDS differed between the two groups.
