Weak Near‐Field Behavior of a Tsunami Earthquake: Toward Real‐Time Identification for Local Warning
Published 2019-08-01“…Previous teleseismic observations found that they radiate seismic waves weakly. They should therefore not be strongly felt in the near field, but to date no near‐source seismic recordings of these events exist that confirm this. …”

Deep nightside photoelectron observations by MAVEN SWEA: Implications for Martian northern hemispheric magnetic topology and nightside ionosphere source
Published 2016-09-01“…Such observations imply the presence of closed crustal magnetic field loops that cross the terminator and extend thousands of kilometers to the deep nightside. This occurs over the weak northern crustal magnetic source regions, where the magnetic field has been thought to be dominated by draped interplanetary magnetic fields (IMF). …”

Discussion on influence and application of non-uniform working resistance of roof anchors on weak face of scouring
Published 2025-04-01“…In combination with the strengthening measures of the unit support, it is found through calculation that the roof can withstand the rock burst of more than 5 powers of strong mine earthquake and meet the requirements of local rock burst prevention. Based on the regional - local secondary rock burst risk assessment system required by the Rules for the Prevention and Control of Rock Burst in Coal Mines (2018), the three-level (namely, regional - local - weak surface) risk assessment method is proposed and discussed in application, which facilitates the prevention and control of weak surface rock burst risks.…”

Human Capital and Institutional Capacity as Drivers of Local Revenue Efficiency: Evidence from Tanzanian Local Government Authorities
Published 2025-08-01“…Local Government Authorities (LGAs) in Tanzania are central to mobilizing own-source revenues, which are essential for financing local development and delivering public services, yet many continue to underperform despite reforms such as the Local Government Finance Act (1982, revised 2010) and adoption of electronic revenue collection systems, collecting on average only 65–70% of their projected revenue potential (PO-RALG, 2022; URT, 2019). …”

Statistical Investigation of the Frequency Dependence of the Chorus Source Mechanism of Plasmaspheric Hiss
Published 2021-03-01“…Abstract We use data from eight satellites to statistically examine the role of chorus as a potential source of plasmaspheric hiss. We find that the strong equatorial (|λm| < 6°) chorus wave power in the frequency range 50 < f < 200 Hz does not extend to high latitudes in any magnetic local time sector and is unlikely to be the source of the low frequency plasmaspheric hiss in this frequency range. …”
