The Liaoning Province in the northeastern part of the North China Craton(NCC) hosts several tremolite jade(nephrite) deposits. Here we investigate the Sangpiyu tremolite jade deposit where the relationship between abundant graphite inclusions within the jade remains enigmatic. We employ petrography, electron probe microanalysis, X-ray-diffraction, and Raman spectroscopy to characterize the tremolite jade and its inclusion minerals. The Sangpiyu jade is predominately composed of tremolite with minor calcite, dolomite, serpentine, titanite, zoisite, allanite, chlorite,apatite, chromite and graphite. Raman spectroscopy of graphite inclusions shows that the D1/G intensity ratio ranges from 0.78 to 0.88 in deep green samples and from 0.05 to 0.23 in dark green samples. The ranges of D1/(D1 + G) integral area ratio for these types are from 0.0548 to 0.3037 and 0.5528 to 0.7355 respectively. The formation temperature of graphite inclusions in the dark green tremolite jade is computed as 549.8 ℃, whereas that for the deep green sample is about343.2 ℃. Our results suggest that the jade formation occurred in a multi-stage process through the action of hydrothermal fluids and metamorphism possibly in a subduction-related setting at moderate to high temperatures.

研究一种基于源信号高阶统计信息的矩阵联合近似对角化独立元分析(jade-ICA)方法,并将其应用于滚动轴承故障声发射(AE)信号的盲源分离。滚动轴承的声发射源信号一般具有衰减性和准周期性,多组信号间还具有时差性,信号被多个传感器接收。通过最大程度的联合近似对角化,可以使源信号与分离信号有效的一一对应,克服非线性和时差的影响;通过高阶统计的高斯噪声不敏感性可以有效抑制随机观测噪声对分离结果的影响。选用相关系数、二次残差、性能指数和频谱特征构成系列时频域评价指标对分离结果进行较为全面的验证。仿真结果证明了该方法的可行性和有效性。

The geochemical and U-series isotopic characteristics of hydrothermal sulfide samples from the jade site (127°04.5′E, 27°15′N, water depth 1300-1450 m) at jade site in the Okinawa Trough were analyzed. In the hydrothermal sulfide samples bearing sulfate (samples HOK1 and HOK2), the LREEs are relatively enriched. All the hydrothermal sulfide samples except HOK1 belong to Zn-rich hydrothermal sulfide. In comparison with Zn-rich hydrothermal sulfides from other fields, the contents of Zn, Pb, Ag, Cd, Au and Hg are higher, the contents of Fe, Al, Cr, Co, Ni, Sr, Te, Cs, Ti and U lower, and the 210Pb radioactivity ratios and 210Pb/Pb ratios very low. In the hydrothermal sulfide mainly composed of sphalerite, the correlations between rare elements Hf and U, and Hf and Mn as well as that between dispersive elements Ga and Zn, are strongly positive; also the contents of Au and Ag are related to Fe-sulfide, because the low temperature promotes enrichment of Au and Ag. Meanwhile, the positive correlations between Fe and Bi and between Zn and Cd are not affected by the change of mineral assemblage. Based on the 210Pb/Pb ratios of hydrothermal sulfide samples (3.99×10-5-5.42×10?5), their U isotopic composition (238U content 1.15-2.53 ppm, 238U activity 1.07-1.87 dpm/g, 234U activity 1.15-2.09 dpm/g and 234U/238U ratio 1.07-1.14) and their 232Th and 230Th contents are at base level, and the chronological age of hydrothermal sulfide at jade site in the Okinawa Trough is between 200 and 2000 yr.

Having beautiful colours and fine features, Xiuyan jade is famous in the world. Mineralogically, Xiuyan jade is serpentine jade. XRD, IR and TEM studies indicate that the jade consists mainly of antigorite (m{Mg3(1-1/m)[Si2O5](OH)1+3(1-2/m}) with a minor amount of chrysotile. Two favourite samples (PxA, Px1-1), chosen for research on Fe Mossbauer spectra, are only antigorite. Studies indicate that: a. iron ion in antigorite enters the lattice as impurity; b. Fe2+ and Fe3+ substitute for Mg in the coordination octahedron; and c. the colour of jade is related to content of Fe, and Fe2+/Fe3+≤1 is favourite for colour-forming.

研究了复杂多径环境下DOA估计问题,提出了基于jade盲源分离算法的一种新方法。该方法在信号方向矢量没有任何先验知识的情况下,通过jade盲辨识技术对阵列流型矩阵进行估计,并将多径环境下的方向矢量看成是由多个复正弦信号线性混合而成,进而利用频谱分析的方法实现信号的DOA估计。经过仿真验证,新方法可以对来波方位相同的2个信号进行分辨,且在多径环境下的稳定性要优于Toplitz近似算法,在信源数(含相干多径信号)大于阵元数时仍然可以使用。

To the Editor:Atopic dermatitis(AD)is a chronic inflammatory skin disorder with a relapsing-remitting disease course that warrants flexible dosing.[1,2]In China,abrocitinib,an oral,once-daily,Janus kinase 1-selective inhibitor,is approved at a 100 mg starting dose for adults with refractory moderate-to-severe AD who did not inadequately respond to other systemic therapies(i.e.,corticosteroids or biologics),or for whom these treatments are not *** the response achieved with abrocitinib 100 mg is inadequate,200 mg dosing can be considered,which could be administered as a short-term treatment(≤12 weeks).[3]The phase 3 jade REGIMEN trial(***,NCT03627767)evaluated maintenance of response with continuous-dose abrocitinib(200 mg),reduced-dose abrocitinib(100 mg),or drug withdrawal(placebo)in patients with moderate-to-severe AD who responded to abrocitinib induction therapy.[4]Here,we aimed to characterize the efficacy and safety of abrocitinib in the Chinese mainland subgroup within jade REGIMEN.

提出了特征矩阵联合对角化(jade)结合超限学习机(ELM)的稳健建模方法,并应用于砂梨成熟度的鉴别。砂梨近红外光谱是多种独立化合物光谱信号的随机线性混合,首先采用多元散射校正和小波变换去除原始光谱噪声,再利用jade提取独立光谱,得到包含独立化合物浓度信息的混合矩阵;随后使用ELM算法,通过调节隐层节点个数建立稳健性强的成熟度鉴别模型。jade利用高阶累积量全面提取原始光谱的幅值、相位信息,降低不同化合物之间的光谱干扰,而ELM隐层节点参数随机生成,两者的有机结合可使所建模型稳健性强,有利于模型的传递与共享。该方法应用于砂梨4种不同成熟度的鉴别,所建模型预测准确率为96.67%。
