In space-borne gravitational wave detection, the remanent magnetic moment of test masses is one primary contributors to residual acceleration noise. During ground phase, precisely measuring under an ultra-weak field crucial for assessing its suitability space mission. this work, we developed a compound pendulum apparatus within shielding room, utilizing pendulum’s periodic motion convert into modulated field. The measurement resolution reaches level 0.2 nAm2.
Abstract We have carried out the Galactic Plane Pulsar Snapshot (GPPS) survey by using Five-hundred-meter Aperture Spherical radio Telescope (FAST), most sensitive systematic pulsar in plane. In addition to more than 500 pulsars already discovered through normal periodical search, we report here discovery of 76 new transient sources with sporadic strong pulses, detected newly developed module for a single-pulse search. Their small DM values suggest that they all are rotating transients...
The lower Cambrian Yurtus Formation (Є1y) in the Tarim Basin, characterized by its high organic matter content, serves as a critical source rock for oil and gas exploration platform basin.

This study reports a new species and record of Proctolaelaps. Proctolaelaps taiyuanensis sp. nov. was found on the body surface Dendroctonus valens LeConte (Coleoptera: Scolytinae); bickleyi (Bram) collected from culture medium lab-raised Ostrinia furnacalis (Guenée) (Lepidoptera: Crambidae). An identification key to China is presented.
Abstract Binary millisecond pulsars with a massive white dwarf (WD) companion are intermediate-mass binary (IMBPs). They formed via the Case BB Roche-lobe overflow (RLO) evolution channel if they in compact orbits an orbital period of less than 1 day. fairly rare known pulsar population, only five such IMBPs have been discovered before, and one them is globular cluster. Here we report six orbit, PSRs J0416+5201, J0520+3722, J1919+1341, J1943+2210, J1947+2304 J2023+2853, during Galactic Plane...

Sea cucumber, Apostichopus japonicus (Selenca), tolerates salinity fluctuations inhabiting intertide zone. This study deals with growth, food intake, conversion and the bioenergetic responses of red variant (wet weight 2.60 ± 0.11g) green 2.56 0.08 g) A. to different salinities 22, 26, 30, 34, 38 psu at 16.5 0.5°C. The results showed that had a significant effect on specific growth rate (SGR) both variants (P < 0.05). Both colour sea cucumber highest SGR 30 psu, then decreased when below or...
Abstract Astrometric positions of the Neptunian Satellite Triton are given for opposition Neptune years 1996, 2003, 2005 and 2006. The 943 observed were obtained at Cassegrain focus a 156-cm reflector. In our reduction, up-to-date catalogue stars UCAC2 was chosen to ensure proper astrometric calibration. Our compared theoretical provided from JPL IMCCE ephemerides. minus calculated residuals have s.d. values order 0.04 arcsec.
Abstract How pulsars radiate is a long-standing problem. Detailed polarization measurements of individual pulses shed light on currently unknown emission processes. Recently, based supersensitive observations, dwarf have been recognized as weak narrow often appearing during the nulling state.

We report the timing-analysis results obtained for Rotating Radio Transient (RRAT) J1819−1458 from regular timing observations at 1.54 GHz using Urumqi 25-m radio telescope between 2007 April and 2008 March. RRAT is a relatively young highly magnetized neutron star discovered by its sporadic short bursts in Parkes Multibeam Pulsar Survey data. In 94 h of observation data, we detected total 162 dispersed with signal-to-noise ratios (S/Ns) above 5 σ threshold. Among them, five clearly show...
In 2003–2004, we obtained 115 new observations of Phoebe, the 9th Saturnian faint satellite (visual magnitude about 16.5). We used a large CCD detector ( pixels) mounted on 1.56 m astrometric reflector at Sheshan Station, near Shanghai. our reduction, an up-to-date catalogue stars, UCAC2 (Zacharias et al. 2004), was chosen to ensure proper calibration. A comparison three recently available, high quality ephemerides, including JPL SAT185 by Jacobson (2004b), has shown that most observed...

Atmospheric data forecasting traditionally relies on physical models, which simulate atmospheric motion and change by solving dynamics, thermodynamics, radiative transfer processes. However, numerical models often involve significant computational demands time constraints. In this study, we analyze the performance of Gated Recurrent Units (GRU) Long Short-Term Memory networks (LSTM) using over two decades sounding from Xisha Island Observatory in South China Sea. We propose a hybrid model...
