    Abstract The present study examined the defense responses of toxigenic Pseudo-nitzschia species (P. multiseries) to a mixotrophic dinoflagellate, Lepidodinium sp., and its associated cues. We evaluated their responses to different predation risks, including direct physical contact and indirect interactions facilitated by cues from Lepidodinium sp. during active feeding on heterospecific prey (Rhodonomas salina), limited feeding on conspecific prey (P. multiseries) and non-feeding (autotrophic growth in f/2 medium) states. This study is the first investigation of these trophic interactions. Our results demonstrated a significant increase in cellular domoic acid (cDA) in P. multiseries when exposed to Lepidodinium sp. and its associated cues, which was 1.38 to 2.42 times higher than the non-induced group. Notably, this increase was observed regardless of Lepidodinium sp. feeding on this toxic diatom and nutritional modes. However, the most significant increase occurred when they directly interacted. These findings suggest that P. multiseries evaluates predation risk and increases cDA production as a defensive strategy against potential grazing threats. No morphological changes were observed in P. multiseries in response to Lepidodinium sp. or its cues. P. multiseries cultured in flasks of Group L+P-P showed a decrease in growth, but Group L-P and Group L+R-P did not exhibit any decrease. These results suggest a lack of consistent trade-offs between the defense response and growth, thus an increase in cDA production may be a sustainable and efficient defense strategy for P. multiseries. Furthermore, our findings indicate that P. multiseries had no significant impact on the fitness (cell size, growth and/or grazing) of Lepidodinium sp. and R. salina, which suggests no evident toxic or allelopathic impacts on these two phytoplankton species. This study enhances our understanding of the trophic interactions between toxic diatoms and mixotrophic dinoflagellates and helps elucidate the dynamics of Harmful Algal Blooms, toxin transmission, and their impact on ecosystem health.

    Abstract [Objective] Cultivated land resources are the main material basis for food production. Analyzing the characteristics of the spatial and temporal changes of cultivated land resources in the typical black soil region has important reference value for optimizing the allocation of cultivated land resources. [Methods] Based on the land use data of four periods from 1986 to 2020 in the typical black soil region of Northeast China, the quantitative change of cultivated land resources characterized by the increase and decrease of cultivated land area were revealed. Taking the change of cultivated land spatial pattern as the breakthrough point, the characteristics of cultivated land resource quality change represented by site conditions were analyzed. On this basis, the driving factors of spatial and temporal changes of cultivated land resources were analyzed. [Results] (1) From 1986 to 2020, the area of cultivated land in the typical black soil region in Northeast China had been increasing, with a net increase of 2.51 × 104 km2, of which the largest increase occurred from 1986 to 2000, and the areas with more dramatic changes in cultivated land were concentrated in the southern foot of the Greater Xing’an Mountains, the Sanjiang Plain, and the areas surrounding the three provincial capital cities of the region; (2) For more than 30 years, due to the continuous movement of the center of gravity of the cultivated land to the northeast, the average temperature of the cultivated land area in the typical black soil region decreased by 0.20℃, the average humidity increased by 0.12%, and the average slope showed the change characteristics of first increasing and then decreasing; Compared with the transferred-out farmland, the temperature condition of the farmland that was transferred in was always poor, the humidity condition was generally superior, the slope condition was poor at the beginning, and better than the transferred-out farmland at a later stage; (3) In areas with low temperature (-1℃-2℃), high humidity (67%-71%), ...

    Abstract The CCT [CONSTANS (CO), CO-like, and TIMING OF CAB EXPRESSION1 (TOC1)] gene family is involved in photoperiodic flowering and adaptation to different environments. In this study, 39 CCT family genes from the poplar genome were identified and characterized, including 18 COL, 7 PRR, and 14 CMF TFs. Phylogenetics analysis showed that the PtrCCT gene family could be classified into five classes (Classes I-V) that have close relationships with Arabidopsis thaliana. Eight pairs of PtrCCTs had collinear relationships through interchromosomal synteny analysis in poplar, suggesting segmental duplication played a vital role in the expansion of the poplar CCT gene family. Besides, synteny analyses of the CCT members among poplar and different species provided more clues for PtrCCT gene family evolution. Cis-acting elements in the promoters of PtrCCTs predicted their involvement in light responses, hormone responses, biotic/abiotic stress responses, and plant growth and development. Eight members of the PpnCCT gene family were differentially expressed in the apical buds and leaves of triploid poplar compared to diploids. We then focused on PpnCCT39 upregulated in triploid poplars and showed that PpnCCT39 was localized in the nucleus, chloroplast, and cytoplasm and could interact with CLPP1 in the chloroplast. Overexpression of PpnCCT39 in poplar increased chlorophyll contents and enhanced photosynthetic rate. This study provided comprehensive information for the CCT gene family and set up a basis for its function identification in poplar.

    Abstract The financial market is a complex system, which has become more complicated due to the sudden impact of the COVID-19 pandemic in 2020. As a result there may be much higher degree of uncertainty and volatility clustering in stock markets. How does this "black swan" event affect the fractal behaviors of the stock market? How to improve the forecasting accuracy after that? Here we study the multifractal behaviors of 5-min time series of CSI300 and S&P500, which represents the two stock markets of China and United States. Using the Overlapped Sliding Window-based Multifractal Detrended Fluctuation Analysis (OSW-MF-DFA) method, we found that the two markets always have multifractal characteristics, and the degree of fractal intensified during the first panic period of pandemic. Based on the long and short-term memory which are described by fractal test results, we use the Gated Recurrent Unit (GRU) neural network model to forecast these indices. We found that during the large volatility clustering period, the prediction accuracy of the time series can be significantly improved by adding the time-varying Hurst index to the GRU neural network.

    Abstract This article describes a power-efficient, high dynamic range (DR) incremental ADC (IADC) for wearable biopotential signals recording, where DC and low-frequency disturbances such as electrode offset, 50/60 Hz interference and motion artifact must be tolerated. To achieve a wide DR, the IADC performs a three-step conversion by combining zoom-SAR and extended counting (EC) on top of a second-order incremental delta-sigma modulator (ΔΣM). The hybrid architecture notably reduces the oversampling ratio (OSR) with respect to conventional incremental ΔΣMs, while using the EC further improves the Signal-to-Noise-and-Distortion Ratio (SNDR) by 7.4 to 25.6 dB. Fabricated in a 0.18-μm CMOS technology, the IADC achieves 107.6-dB DR, 104.9-dB peak SNR, and 99.3-dB peak SNDR at 2 kS/s while dissipating 130 μW from 1.8-V (analog) / 1.2-V (digital) supply. This translates to a highly competitive FoM

    Abstract We aimed to obtain the optimal formula for human milk fat substitute (HMFS) through a combination of software and an evaluation model and further verify its practicability through an animal experiment. The results showed that a total of 33 fatty acid (FA) and 63 triglyceride (TAG) molecular species were detected in vegetable oils. Palmitic acid, oleic acid, linoleic acid, 18:1/16:0/18:1, 18:2/16:0/18:2, 18:1/18:1/18:1 and 18:1/18:2/18:1, were the main molecular species among the FAs and TAGs in the vegetable oils. Based on the HMFS evaluation model, the optimal mixed vegetable oil formula was blended with 21.3% palm oil, 2.8% linseed oil, 2.6% soybean oil, 29.9% rapeseed oil and 43.4% maize oil, with the highest score of 83.146. Moreover, there was no difference in the weight, blood routine indices or calcium and magnesium concentrations in the feces of the mice between the homemade mixed vegetable oil (HMVO) group and the commercial mixed vegetable oil (CMVO) group, while nervonic acid (C24:1) and octanoic acid (C8:0) were absorbed easily in the HMVO group. Therefore, these results demonstrate that the mixing of the different vegetable oils was feasible via a combination of computer software and an evaluation model and provided a new way to produce HMFS.
