Summary: This paper investigates the genesis and rapid weakening of North Indian Ocean tropical cyclone Lehar in November 2013, finding that the intrusion of dry air from the north was the primary factor leading to its rapid weakening.

Summary: In this study, the 2013 November 12th hard X-ray flare-associated solar energetic electron event was investigated using joint EUV jet observations. The observed energy spectrum of the solar energetic electrons showed a triple-power-law shape, which is different from previous jet-related events. The associated hard X-ray emissions also displayed three distinctive peaks. Based on analysis, it is proposed that the interchange-reconnection model triggered by emerging flux could explain this jet event.

Summary: We present the first optical photometric monitoring of 12 newly discovered blazars from the ICRF - Gaia CRF astrometric link. Variability was confirmed in 10 sources, with two sources possibly being variable. Additionally, three sources displayed large amplitude brightness change of more than one magnitude. Our results suggest that bluer-when-brighter variations are more common among the studied sources. We also discuss various AGN emission models that can explain our findings.

Summary: Thermoplastic materials have a reputation for long-term reliability in low-pressure gas and water distribution pipe systems, but concerns remain regarding Slow Crack Growth (SCG) and Rapid Crack Propagation (RCP) failures. The study investigated the RCP resistance of five different polyamide (PA) 12 grades using the ISO 13477 Small-Scale Steady State (S4) test, revealing structure-property relationships that can be used for more efficient evaluation of each grade.

Summary: Aldehydes are known to have carcinogenic effects and can negatively impact health. This study analyzed serum aldehyde concentrations in a U.S. population sample and found tobacco smoke to be a significant source of exposure to certain aldehydes. The research highlighted the importance of understanding aldehyde exposure and its potential health effects, especially in relation to tobacco smoke.

Summary: This retrospective analysis compared the performance of APP-led rapid response teams with that of teams led by a medical resident. The results showed no significant differences in interventions between the two groups, although APP-led teams handled more calls. Further prospective studies are needed to confirm these findings.

Summary: Numerous studies have been conducted on involuntary weight loss (IWL) since the 1980s, but this study focused on patients with isolated IWL attending a rapid diagnostic unit (RDU) between 2005 and 2013. The results showed that almost a quarter of patients were diagnosed with cancer, and the mortality rate at 12 months was higher in this group compared to others. It emphasizes the importance of ruling out malignancy in patients presenting with IWL.

Summary: The (CoCrNi)88Mo12 dual-phase MEA is fabricated to enhance the matrix and achieve excellent cryogenic wear performance. The study reveals that a significant wear reduction of 73% is achieved as the temperature decreases from 233 K to 113 K, and the friction-induced amorphous layer underneath the worn surface plays a crucial role in the excellent wear behavior at 113 K. The low stacking fault energy of the CoCrNi-rich matrix at cryogenic temperature and the high solute concentration of Mo contribute to the rapid amorphization process.

Summary: Deuterium, a low abundance stable hydrogen isotope, negatively affects cell growth in high concentrations. Through laboratory evolution, strains with increased fitness in deuterium-based media were isolated, showing multiple genetic adaptations pathways. Deuteration of proteins is crucial for structural biology applications, and evolved strains adapted for efficient production of perdeuterated soluble and membrane proteins.

Summary: This study analyzes surface observations and satellite retrieval data to determine the increase in surface ozone in the North China Plain region, finding that anthropogenic emission control strategies and changes in aerosol concentrations are the main driving factors. Numerical simulations indicate that reduction of O3 precursor emissions and aerosol radiative effect contribute significantly to the increase in surface ozone, emphasizing the importance of considering aerosol chemistry in future research for developing more effective emission control strategies.

Summary: This study used machine learning techniques to analyze the trends of air pollutants in 12 Chinese mega-cities from 2013 to 2020, finding that the concentrations of all pollutants except O-3 showed a decline, while O-3 concentrations increased. The effectiveness of the clean air actions was evaluated by removing the meteorological influence, and it was found that meteorology can have both positive and negative impacts on pollutant concentrations depending on the type of pollutants, locations, and time periods.

Summary: The study evaluates the early data of a pooled SARS-CoV2 testing program in Massachusetts K-12 public schools, using innovative design elements such as in-school pod pooling. The results show that with sufficient staffing support and low pool positivity rates, pooled sample collection and reflex testing were feasible for schools. This approach combines in-school pooling, primary testing by RT-PCR, and Ag RDT reflex/deconvolution testing for efficient screening of K-12 students and staff.

Summary: In this paper, the multiwavelength observations of an erupting prominence and the associated coronal mass ejection (CME) on 13 May 2013 are reported. The prominence is supported by a highly twisted magnetic flux rope and shows rapid rotation in the counterclockwise direction during the rising motion. The prominence eruption is most probably triggered by kink instability. The 3D morphology and positions of the associated CME are derived using the graduated cylindrical shell (GCS) modeling.
