title: Euproctis digramma nucleopolyhedrovirus strain 424, complete genome
title: Euproctis digramma nucleopolyhedrovirus strain 424, complete genome

description: Artaxa digramma is a lepidopteran pest distributed throughout southern China, Myanmar, Indonesia, and India. Artaxa digramma nucleopolyhedrovirus (ArdiNPV) is a specific viral pathogen of A. digramma and deemed as a promising biocontrol agent against the pest. In this study, the complete genome sequence of ArdiNPV was determined by deep sequencing. The genome of ArdiNPV contains a double-stranded DNA (dsDNA) of 161,734 bp in length and 39.1% G+C content. Further, 149 hypothetical open reading frames (ORFs) were predicted to encode proteins &gt;50 amino acids in length, covering 83% of the whole genome. Among these ORFs, 38 were baculovirus core genes, 22 were lepidopteran baculovirus conserved genes, and seven were unique to ArdiNPV, respectively. No typical baculoviral homologous regions (hrs) were identified in the genome. ArdiNPV had five multi-copy genes including baculovirus repeated ORFs (bros), calcium/sodium antiporter B (chaB), DNA binding protein (dbp), inhibitor of apoptosis protein (iap), and p26. Interestingly, phylogenetic analyses showed that ArdiNPV belonged to Clade II.b of Group II Alphabaculoviruses, which all contain a second copy of dbp. The genome of ArdiNPV was the closest to Euproctis pseudoconspersa nucleopolyhedrovirus, with 57.4% whole-genome similarity. Therefore, these results suggest that ArdiNPV is a novel baculovirus belonging to a newly identified cluster of Clade II.b Alphabaculoviruses.

title: Reconstructing sources location of visual color cortex by the Task-irrelevant visual stimuli through machine learning decoding
title: Reconstructing sources location of visual color cortex by the Task-irrelevant visual stimuli through machine learning decoding

description: Visual color sensing is generated by electrical discharges from endocranial neuronal sources that penetrate the skull and reach to the cerebral cortex. However, the space location of the source generated by this neural mechanism remains elusive. In this paper, we emulate the generation of visual color signal by task-irrelevant stimuli to activate brain neurons, where its consequences over the cerebral cortex is experimentally tracked. We first document the changes to brain color sensing using electroencephalography (EEG), and find that the sensing classification accuracy of primary visual cortex regions was positively correlated with the space correlation of visual evoked potential (VEP) power distribution under machine learning decoding. We then explore the decoded results to trace the brain activity neural source location of EEG inversion problem and assess its reconstructive possibility. We show that visual color EEG in primary visual cortex can reconstruct endocranial neuronal source location, through the machine learning decoding of channel location.

title: VNIR and MIR spectra of olivine uderwent different degrees of simulated space weathering

description: We irradiate olivine grains by using pulsed laser to simulate varying degrees of micrometeorite bombardments. Two different energy levels for the pulse have been used, i.e. 25 mJ/pulse and 50 mJ/pulse. Reflflectance measurements from 0.5 to 25 µm and radiative transfer calculations were carried out in order to compare them with each other. Detailed lab setting and sample information can be found in Yang et al., (2017). There are two datasets, one is the visible and near-infrared (VNIR) spectra data with a wavelength range of 0.5-2.8 μm, and the other one is the mid-infrared (MIR) spectra data with a wavelength range of 1.3-27 μm. There are seven spectra in each of the datasets, includes: unirradiated, 25mJ_1time, 25mJ_2time, 25mJ_3time, 25mJ_4time, 25mJ_5time, 50mJ_2time, and 50mJ_5time. "Unirradiated" represents the spectrum of the original olivine sample, and 25mJ_1time represents the spectrum of olivine irradiated with a pulse energy of 25 mJ for 1 time, and so on.

title: Effect of dual-pulse temporal shaping on ultraviolet nanosecond laser damage of fused silica surface in high fluence regime
title: Effect of dual-pulse temporal shaping on ultraviolet nanosecond laser damage of fused silica surface in high fluence regime

description: We present the effect of dual-pulse temporal shaping on ultraviolet nanosecond laser damage characteristics of fused silica exit surface in the high fluence regime. The pre-pulse and post-pulse have the opposite effects on the damage behaviors at pulse delay of 20 ns. The pre-pulse irradiation significantly increases the main-pulse threshold to be much higher than the single-pulse threshold, but the post-pulse has little effect on the main-pulse threshold. For near-threshold damage sites, the pre-pulse reduces the average damage size and depth to be smaller than those of single-pulse, while the post-pulse drastically increases the average size and depth to be much larger than single-pulse. The average size of the damage site is monotonously increased from 43.6 µm to 127.9 µm with raising the post-pulse energy. For the pre-pulse case with the shape factor of 0.61, the damage threshold of main-pulse increases with the delay and nearly stabilizes after 10 ns. The underlying mechanism of the temporal-shaping effect on laser damage is discussed based on the switch of the precursor modification to absorption enhancement, which could provide insights for studying ultraviolet laser damage of fused silica optics.

title: Fixed-Time and Predefined-Time Stability of Impulsive Systems
title: Fixed-Time and Predefined-Time Stability of Impulsive Systems

description: Several criteria for fixed-time stability and predefined-time stability of impulsive systems are established. First, sufficient conditions for fixed-time stability of impulsive systems are presented to treat the destabilizing impulses and hybrid impulses involving multiple jump maps by fixed-time control without linear feedback regulation. It determines the robustness of nonlinear systems against impulsive disturbance which has destabilizing and hybrid effect to dynamics. Then, the predefined-time stability of impulsive systems is ensured under the requirement that the hybrid impulses have stabilizing accumulative effect. Finally, the validity of theoretical results is verified by the allocation of mobile agents on a segment via fixed-time control with impulsive regulation.

title: Effect of substitution of concentrate mixture on performance of dorper 50% crossbred sheep

description: The experiment was conducted to evaluate the potential of dried brewer's grains (DBG) to replace concentrate mixture in growing 50% Dorper × Menz crossbred ram lambs fed native pasture hay as basal diet. The experiment was arranged in a randomized complete block design (RCBD) with five treatments and seven replications, and initial body weight and age were used for blocking. Ram lamb from each block was randomly assigned to one of the five treatments. All sheep were fed native pasture hay (NPH) ad libtum at 20% refusal as a basal diet and supplemented with 400g Concentrate mixture (CM) (T1) or 300g DBG + 100 g CM (T2) or 200g DBG + 200g CM (T3) or 100g DBG + 300g CM (T4) or 400g DBG (T5). Natural pasture hay and total dry matter (TDM) intake were similar (P &gt; 0.05) among the treatments. Substitution of 75, 50 and 100% of CM with DBG had greater (P &lt; 0.001) body weight gain than 100% CM supplemented group, and substitution of 25% CM with DBG had an intermediate value. The partial budget analysis revealed that T3 and T5 gave greater net returns of Birr 881.19 and 854.91 per head, respectively.

title: Numerical simulation of nonlinear optical gain modulation in a Raman fiber amplifier
title: 基于非线性光学增益调制拉曼光纤放大器中的数值模拟

description: Nonlinear optical gain modulation (NOGM) in a Raman fiber amplifier is numerically simulated with the generalized nonlinear Schrödinger equation. In the NOGM setup, a single frequency continuous wave seed laser is gain modulated into femtosecond pulses by an ultrafast pump, which can induce strong stimulated Raman scattering in a piece of single mode optical fiber. Different parameters regarding seed, pump and nonlinear gain medium (Raman fiber) are investigated in detail to find the best condition for higher Raman conversion efficiency. Simulated results reveal that the walk-off between pump and Raman pulses due to dispersion is one of the most important factors affecting the NOGM pulse’s performance. Only when the speed of walk-off matches with the one of Raman conversion process can the conversion efficiency be optimized. This work offers a guild-line for the design of a fiber-based NOGM laser, which is able to produce wavelength-agile, femtosecond laser pulses with μJ-level pulse energy under more than 85% efficiency.

title: A dataset of winter crops map in Henan Province from 2019 to 2021
title: 2019-2021年河南省越冬作物分布数据集

description: This data set is based on the Google Earth engine (GEE) cloud computing platform, integrates multi-source remote sensing images, constructs a phenological algorithm, and generates the data set of winter crops in Henan Province from 2019 to 2021. First, the Landsat 7 / 8 and sentinel-2a / b remote sensing images are fused to construct a high spatial-temporal resolution time series data set. Secondly, the phenological differences of overwintering crops and other vegetation under different phenological periods are analyzed, and phenological indicators for classification are extracted, including start of season (SOS), start date of peak (SDP), end of season (EOS), green up speed (Gus) and growing season length (GSL). Finally, based on these phenological indexes, a decision tree model is constructed to extract winter crops at the pixel scale. The phenological algorithm constructed in this study can accurately extract the planting area of overwintering crops, and its user, producer, overall accuracy and kappa coefficient are 98.00%, 98.36%, 97.77% and 0.94 respectively. This data set can provide basic data for the growth monitoring and yield prediction of overwintering crops, help decision makers and producers to formulate reasonable policies and risk management strategies, and also provide data reference for scientific researchers in relevant fields.
