title: The thermal infrared optical depth of mineral dust retrieved from integrated CALIOP and IIR observations

description: Recent studies have suggested that global climate models tend to underestimate dust particle size in particular, the very coarse mode, leading to an underestimated direct radiative effect (DRE) of dust in the longwave (LW) thermal infrared (TIR) region. However, the magnitude of LW DRE remains highly uncertain, because of limited observations of dust optical depth at the TIR (DAODTIR). This study presents a simple approach to retrieve the DAODTIR over the oceans during nighttime through synergistic use of observations from the Infrared Imaging Radiometer (IIR) and the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP), both onboard of the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) mission. For each cloud-free dust-laden profile identified by the IIR-CALIOP observation, a Lookup-Table (LUT) of the 10.6 μm IIR band brightness temperatures (BT) difference (dBT) under different DAODTIR with respect to their dust-free BTs is constructed based on the CALIOP retrieved dust vertical profile and a priori dust scattering properties using a fast radiative transfer model. Then the DAODTIR is retrieved by projecting the IIR-observed dBT on the LUT. Sensitivity studies show that the DAODTIR retrieval at 10.6 μm is more susceptible to the dust particle size distribution (PSD) assumption than dust refractive indices. To estimate the uncertainty caused by PSD assumption, two DAODTIR retrieval products, one based on the dust PSD from the AERONET at Cape Verde and the other on an in situ measured PSD from the recent Fennec campaign, are provided. The retrieval uncertainty is mainly contributed by the BT difference between the observation and simulation using auxiliary atmospheric data. The climatology of the retrieval from 2013 to 2019 shows reasonable spatiotemporal variations of DAODTIR with the global-averaged value of 0.008 and 0.013 based on different pre-assumed dust PSDs. Climatological results agree reasonably well with two independent DAODTIR retrieval products based on the Infrared Atmospheric Sounding Interferometer (IASI) over the active dust transport regions, such as North and Tropical Atlantic (r = 0.9 and r = 0.8) and Indian Ocean (r = 0.8). The seasonal and interannual variation is also well-compared (r = 0.76) with AERONET coarse-mode AOD at 97 selected sites. The synergic CALIOP observation allows the retrieved DAODTIR to directly compare with the extrapolated DAODTIR from DAOD in the visible (i.e., 532 nm), which helps evaluate the observational constraints on DAODTIR. Our study clearly reveals that the retrieved DAODTIR from IIR is much less susceptible to various uncertainties than converted results from CALIOP. It also offers a unique prospect of collocated active lidar and passive IR observations for retrieving dust DAODTIR.

title: Estimating Trends in Male Earnings Volatility with the Panel Study of Income Dynamics

description: The Panel Study of Income Dynamics (PSID) has been the workhorse dataset used to estimate trends in U.S. earnings volatility at the individual level. We provide updated estimates for male earnings volatility using additional years of data. The analysis confirms prior work showing upward trends in the 1970s and 1980s, with a near doubling of the level of volatility over that period. The results also confirm prior work showing a resumption of an upward trend starting in the 2000s, but the new years of data available show volatility to be falling in recent years. By 2018, volatility had grown by a modest amount relative to the 1990s, with a growth rate only one-fifth the magnitude of that in the 1970s and 1980s. We show that neither attrition or item nonresponse bias, nor other issues with the PSID, affect these conclusions.

title: Trends in Earnings Volatility Using Linked Administrative and Survey Data

description: We document trends in earnings volatility separately by gender using unique linked survey data from the CPS ASEC and Social Security earnings records for the tax years spanning 1995–2015. The exact data link permits us to focus on differences in measured volatility from earnings nonresponse, survey attrition, and measurement between survey and administrative earnings data reports, while holding constant the sampling frame. Our results for both men and women suggest that the level and trend in volatility is similar in the survey and administrative data, showing substantial business-cycle sensitivity among men but no overall trend among continuous workers, while women demonstrate no change in earnings volatility over the business cycle but a declining trend. A substantive difference emerges with the inclusion of imputed earnings among survey nonrespondents, suggesting that users of the ASEC drop earnings nonrespondents.

title: DNA Methylation may be a testicular plateau adaptation in Tibetan pig

description: DNA methylation plays an important role in reproduction. Tibetan pigs maintain high sperm motility, even under extreme conditions at high altitudes. However, the DNA methylation mechanisms underlying testicular plateau adaptations in Tibetan pigs remain unclear. We determined the genomic DNA methylation level in the testicular tissues of Tibetan pigs living at high altitudes (TP) and of Yorkshire pigs that migrated to high altitudes (YP) using the fluorescence method. Quantitative real-time PCR and western blots were used to measure the gene and protein expression levels, respectively, of three DNA methyltransferases (DNMT1, DNMT3A, and DNMT3B) and hypoxia-inducible factor 2α (HIF2α). We found that the genomic DNA methylation level and the mRNA and protein expression levels of the four genes were all significantly lower in the testicular tissues of TP than YP. In short, compared with YP, the downregulation of DNA methyltransferases in the TP testes led to lower levels of genomic DNA methylation, which would facilitate higher sperm motility. Meanwhile, HIF2α expression in the TP testes was down-regulated, which might contributes to TP testes’ adaption to the plateau environment. This study provided new insights into the DNA methylation mechanisms underlying plateau adaptations in TP testicles.

title: Circular RNA transcriptome analysis responses to heat stress in the hypothalamus of sows

description: Circular RNAs (circRNAs), as miRNA sponges, have been found to participate in transcriptional control and many important biological processes. Heat stress (HS) severely affects feed intake and milk production of sows. However, the expression and function of circRNAs in the hypothalamus of sows and whether they are involved in the adaptation to HS have not been explored. In this study, RNA sequencing and functional analysis were performed to explore the expression and function of circRNAs in the hypothalamus of heat-stressed sows. Toally, 38,143 circRNAs were identified from the hypothalamus of heat-stressed sows, among which 307 circRNAs (170 upregulated and 137 downregulated) were significantly differentially expressed (DE) in the HS groups compared to the control groups. Their host genes are involved in the cellular component organization or biogenesis, metabolic process, and cellular metabolic process, the MAPK signalling pathway and the TGF-β signalling pathway. And a total of 307 DE circRNAs were found to act as sponges for 457 miRNAs. This research explored the expression profiles of circRNAs in the hypothalamus of heat-stressed sows, which will provide basic data for further investigation of the biological function and the regulatory role of circRNAs in the heat-stressed sows.
