Maternal glycemic status and longitudinal fetal body composition and organ volumes based on three-dimensional ultrasonography

K. Wagner Jessica L. Gleason Zhen Chen Cuilin Zhang Stefanie N. Hinkle

Objective: Gestational diabetes mellitus (GDM) increases the risk of fetal overgrowth, as measured by two-dimensional (2D) ultrasonography. Whether fetal 3D soft tissue and organ volumes provide additional insight into fetal overgrowth is unknown. Research Design & Methods: We prospectively evaluated longitudinal 3D fetal body composition and organ volumes in a diverse US singleton pregnancy cohort (2015-2019). Women were diagnosed with GDM, impaired glucose tolerance (IGT), or normal glucose tolerance (NGT). Up to five 3D ultrasound scans measured fetal body composition and organ volumes; trajectories were modeled using linear mixed models. Overall and weekly mean differences in fetal 3D trajectories were tested across glycemic status, adjusted for covariates.Results: In this sample (N=2427), 5.2% of women had GDM and 3.0% had IGT. Fetuses of women who developed GDM, compared to NGT, had larger fractional arm and fractional fat arm volumes from 26-35 weeks, smaller fractional lean arm volume from 17-22 weeks, and larger abdominal area from 24-40 weeks. Fetuses of women with IGT had similar growth patterns, but manifested later in gestation and with larger magnitudes, and had larger fractional lean arm volume. No overall differences were observed among thigh or organ volumes across glycemic status.Conclusions: Body composition differed in fetuses of GDM pregnancies, including larger arm and abdominal measures across the second and third trimesters. Patterns were similar in IGT pregnancies except occurred later in gestation and with larger magnitudes. Future research should explore how lifestyle and medication may alter fetal fat accumulation trajectories among hyperglycemic pregnancies.

Optimization of volatile oils extraction and β-cyclodextrin inclusion from angelica and safflower of Zhepujiuweirunzao Tang

Chinese New Drugs Journal (2005)

Dian He

Objective:To optimize the processes of volatile oils extraction and β-cyclodextrin (CD)inclusion from angelica and safflower of Zhepujiuweirunzao Tang.Methods:An orthogonal design involving the extracting rate of the volatile oils was designed to evaluate the optimal process of the volatile oils extraction. The process of the inclusion complex of β-CD was optimized based on the transfer and recovery rate of the volatile oils in the complex.Results:The optimal extraction outcome was as follows: the crude herbal materials were soaked into an aqueous solvent (the ratio of water to herbs 8∶1) for 1 hour. Following after the refluxing of extracting solution for 10 hours, the extraction rate of the volatile oils was 3.7 mg·g -1 ( n =6,RSD=10.2%). The optimal inclusion complex condition was as follows:the β-CD formed a complex with the volatile oils in a ratio of 6∶1 under the refluxing and stirring for 1 h at 60℃. The recovery rate of inclusion compounds and the transfer rate of the oils were 79.1% ( n =3,RSD=1.7%) and 89.9%( n =3,RSD=9.1%), respectively. A GC-MS study confirmed that the content of the volatile oils showed no significant difference post the inclusion complex compared with the one prior to the inclusion complex. Conclusion:This optimal processes to manufacture Zhepujiuweirunzao Tang are attainable.

Active surface salt structures of the western Kuqa fold-thrust belt, northwestern China

Geosphere (2014)

Jianghai Li A. Alexander G. Webb Xiang Mao Ingrid Eckhoff Cindy Colón

The western Kuqa fold-thrust belt of Xinjiang Province, China, hosts a series of surface salt structures. Here we present preliminary analysis of the geometry, kinematics, and surface processes of three of these structures: the Quele open-toed salt thrust sheet, Tuzimazha salt wall, and Awate salt fountain. The first two are line-sourced, the third appears to be point-sourced, and all are active. The ∼35-km-long, 200-m-thick Quele open-toed salt thrust sheet features internal folding, salt-lined transfer structures, dissolution topography, flanking growth strata, and alluvial fan/stream-network interactions. The ∼10-km-long, 50-m-wide Tuzimazha salt wall marks a local topographic high, such that fluvial stream networks are deflected by the rising weak tabular salt body. The salt wall is also flanked by growth strata and normal faults. The ∼2-km-long Awate salt fountain represents salt exhumation coincident with the intersection of multiple structures and a river. Therefore this salt body may respond to local structural and/or erosional variations, or it may play a key role determining such variations—or both. Activity along all three structures confirms that active deformation occurs from foreland to hinterland across the western Kuqa fold-thrust belt. Gradual lateral transition from bedded strata to flow-banded halite observed within the Quele open-toed salt thrust sheet implies that similar transitions observed in seismic reflection data do not require interpretation as diapiric cut-off relationships. The surface salt structures of the western Kuqa fold-thrust belt display a variety of erosion-tectonics interactions, with nuances reflecting the low viscosity and high erodibility of salt, including stream deflections, potential tectonic aneurysm development, and even an upper-crustal test site for channel flow–focused denudation models.

Research status and development trend of carbon fiber reinforced polymer hydraulic cylinder

复合材料学报 (2021)

Bing Shuang Xu Huaizhi Zong Junhui Zhang Kun Zhang Hsinpu Huang

Carbon fiber reinforced polymer (CFRP) has been widely used in robotics, aerospace, engineering equipment and other fields for its advantages of thermal shock resistance, high tensile strength and corrosion resistance. Producing hydraulic cylinder with CFRP can greatly improve the lightweight level of hydraulic system and reduce energy consumption further. The paper summarizes the development status of CFRP hydraulic cylinder from five aspects: composite cylinder, piston and piston rod, molding process, sealing and lubrication, and development trends. Then the connection methods between metal and composite material in cylinder and piston are introduced, during which the reference criteria of multi-material design is given in detail. The processing technologies of hand lay-up, filament winding, pultrusion, resin transfer model forming are shown, then the problems of sealing, friction and dynamic response of carbon fiber composite hydraulic cylinder are discussed. Finally, the development trends of carbon fiber reinforced polymer hydraulic cylinder are given from three aspects: coating, processing and post-treatment.

A Low Jitter Current-Mode Multiplying Delay-Locked Loop Applied to High-Precision TDC

2021 IEEE 14th International Conference on ASIC (ASICON) (2023)

Sun Jin Jiahao Hu Ziqi Song Qing Li Dian He

This paper presents a low jitter multiplying delay-locked loop (MDLL) with a current-controlled delay line (DL) for high-precision time-to-digital converter (TDC). A multiphase clock with uniform distribution generated from the delay line is applied directly to the high-precision TDC. To achieve better performance output phase splitting, a voltage-to-current circuit (VTC) is introduced to extend the locking frequency range and enhance frequency tuning linearity of MDLL. Additionally, to decrease the phase noise in the locked state, an improved charge pump (CP) with matched switches is utilized to improve the match between charge and discharge currents. The improved reverse differential delay cell structure can suppress the common mode noise in the delay line, which is used to improve the resolution of TDC. This paper uses 180nm CMOS technology to realize a MDLL with an output of 65MHz-325MHz, occupying an area of 0.084mm2. The simulation results show that the total power consumption of the chip core is 9.41mW@200MHz under 1.8V power supply, the locking voltage is 820mV when the MDLL loop is stable, the RMS jitter is 1.73ps@200MHz, and the standard deviation of each 45° adjacent phase interval is less than 1.5ps.
