title: A dataset of the Poyang Lake coastlines in dry and wet seasons during 2000 – 2020
title: 2000–2020年鄱阳湖干湿季边界数据集

description: Poyang Lake is located in the south of Jiangxi Province and it is the largest freshwater lake directly connected to the Yangtze River. In the wet seasons, the lake was usually more than 3000 km2 and in the dry seasons, the lake retreated to lower than 800 km2. Poyang Lake is very important to regulate the water flows between the lake and the Yangtze River and is valid to protect biological resources and promote economic development of the watershed. Based on high-frequency MODIS data, we obtained series of Poyang Lake coastlines in wet and dry seasons during 2000–2020. This dataset includes 42 series of the Poyang Lake peripheries. The dataset can delineate the tempo-spatial dynamics of the lake inundations and can serve as scientific data to ecological protect and water resources management.

title: 《全光纤激光外差光谱仪测量大气二氧化碳和甲烷》论文数据集

description: An all fibered NIR-LHR has been developed for operation in ground-based solar occultation mode. A 1x2 fiber optical switch is employed to modulate solar radiation, which makes the system more stable and compact. High resolution NIR-LHR spectra of atmospheric CO2 and CH4 were obtained by employing two DFB lasers (1.6 μm and 1.65 μm) as the local oscillators. After power calibration, the wavenumbers were precisely calibrated using a correlation correction method. Subsequently, an OEM and RFM based retrieval algorithm was developed for retrieval of the vertical profiles, column-averaged abundances and mixing ratios in dry air of atmospheric CO2 and CH4. Finally, the long term NIR-LHR results were validated by comparing the GOSAT results during the same time period, which indicates a uncertainty region of 0.15%-0.7% for XCH4 and 0.17%-0.5% for XCO2, respectively. The data set contains data such as relevant original spectra, atmospheric parameters and corresponding dates.

title: &lt;基于高分辨率激光外差光谱反演大气CO2柱浓度及系统测量误差评估方法&gt;数据集

description: In this dataset, a near-infrared laser heterodyne spectrometer developed by the laboratory is used to investigate the inversion of greenhouse gas column concentration and approximately evaluate the system measurement errors based on the optimal estimation algorithm. Firstly, the spectral database and the calculation results from the reference forward model are compared with the ground-based FTIR results, thereby selecting the detection window, the corresponding laser and detector. Secondly, the optimal estimation concentration inversion algorithm based on the reference forward model is established, and the LevenbergMarquardt (LM) iterative method is adopted to realize the inversion of the concentration and vertical distribution profile of atmospheric CO2 column in the whole layer, and the long-term observation comparative experiment is carried out to verify the feasibility of this algorithm. Finally, by simulating the selected detection window spectrum in different white noise, the approximate corresponding relationship between the system signal-noise-ratio (SNR) and CO2 column concentration measuring error is eventually obtained.

description: A novel method for laser frequency locking and intensity normalization in wavelength modulation spectroscopy (WMS) based gas sensor system is described in this dataset. The center spacing between two second harmonic peaks demodulated from the rising and falling edges of a scanning triangular wave (for wavelength scan), is employed as frequency locking reference. Amplitude of the directly acquired sine signal (for wavelength modulation) in the interval apart from absorption feature is employed as intensity normalization reference. A 50 ppm CH4:N2 sample sealed in a multi-pass cell at 1 atm was employed as the target analyte for demonstration. The frequency locking significantly improves measurement accuracy, and the introduced intensity normalization method realized a ~3 times SNR improvement as compared to the commonly used 1f normalization method under frequency locking conditions.

title: A simple threat detection strategy in mice
title: A simple threat detection strategy in mice

description: Background: Avoiding danger and accessing environmental resources are two fundamental, yet conflicting, survival instincts across species. To maintain a balance between these instincts, animals must efficiently distinguish approaching threats from low-threat cues. However, little is known about the key visual features that animals use to promptly detect such imminent danger and thus facilitate an immediate and appropriate behavioral response. Results: We used an automatic behavior detection system in mice to quantify innate defensive behaviors, including freezing, flight, and rearing, to a series of looming visual stimuli with varying expanding speeds and varying initial and final sizes. Looming visual stimuli within a specific “alert range” induced flight behavior in mice. Looming stimuli with an angular size of 10–40° and an expanding speed of 57–320°/s were in this range. Stimuli with relatively low expanding speeds tended to trigger freezing behavior, while those with relatively high expanding speeds tended to trigger rearing behavior. If approaching objects are in this “alert range,” their visual features will trigger a flight response; however, non-threatening objects, based on object size and speed, will not. Conclusions: These results indicate a simple strategy in mice that is used to detect predators and suggest countermeasures that predators may have taken to overcome these defensive strategies. Keywords: Automatic behavior detection, Innate fear, Alert range, Freezing, Flight, Rearing

title: Models and data supporting the paper "A Morphotropic Phase Boundary in MA(1-x)FA(x)PbI3: Linking Structure, Dynamics, and Electronic Properties"

description: This record contains a database of atomic structures for the MA(1-x)FA(x)PbI3 system with reference data from density functional theory calculations (reference-structures.db) that was used for training the machine-learned interatomic potential model described and used in the associated publication. The database is in SQL format and is accessible via the database module of the atomic simulation environment.

The record furthermore contains the neuroevolution potential model (nep.txt) that was used for the production runs in the associated publication along with five models (nep-split*.txt) that were trained on different (random 90-10) splits of the reference data. The latter can be used as an ensemble model to assess the uncertainty of predictions.

Finally, there is a short Python script (demo.py) that demonstrates how the database can be accessed and the model used. This script has been tested on Python 3.12.3 using ase version 3.23.1b1 and calorine version 3.0.

title: Database on the yield of α-pinene oxidation to form secondary organic aerosols in an oxidation flow reactor
title: 氧化流动反应器中α-蒎烯氧化形成二次有机气溶胶的产率数据集

description: Based on the self-designed and developed OFR, the experimental study on the oxidation of α-pinene to SOA was carried out. The reactor is capable of independently controlling temperature, humidity and oxidant concentration. For particles larger than 50 nm, the reactor has very small wall. In the O3 oxidation experiments, SOA yields were found to be dependent on O3 concentration, precursor concentration and SOA mass concentration. In the OH radical oxidation experiments, SOA yields were dependent on relative humidity, precursor concentration, SOA mass concentration, OH radical concentration and acidic seed aerosol concentration. The addition of acidic seed aerosols significantly increased the particle number concentration and particle size, resulting in a factor of 1.2-1.5 increase in SOA yield. In addition, The results of this reactor were compared with those of previous reactor/smog chamber in the literature, and the oxidation performance of this OFR was validated. These results can provide technical support and theoretical guidance for the continued use of OFR to simulate the ageing of biomass combustion emissions in the future.
