Focal points in tacit bargaining problems:Experimental evidence [PDF]
, 2013 We use a new experimental design to test Schelling's hypotheses about the nature and effectiveness of focal points in tacit bargaining problems. In our design, as in many real-world bargaining problems, each player's strategies are framed as proposals ...

Focal mechanism inversion of the 2018 MW7.1 Anchorage earthquake based on high-rate GPS observation
Geodesy and Geodynamics, 2021 The MW7.1 Anchorage earthquake is the most destructive earthquake since the 1964 MW9.2 great Alaska earthquake in the United States. In this study, high-rate GPS data and near-field broadband seismograms are used in separate and joint inversions by the ...

First-Motion Focal Mechanism Solutions for 2015–2019 M ≥ 4.0 Italian Earthquakes [PDF]
Frontiers in Earth Science, 2021 A list of 100 focal mechanism solutions that occurred in Italy between 2015 and 2019 has been compiled for earthquakes with magnitude M ≥ 4.0. We define earthquake parameters for additional 22 seismic events with 3.0 ≤ M < 4.0 for two specific key zones: Muccia, at the northern termination of the Amatrice–Visso–Norcia 2016–2018 central Italy ...

Broadband Waveform Modeling Over a Dense Seismic Network [PDF]
, 2006 We developed a "two-way" calibration technique for studying clustered events, particularly their mechanisms and rupture directivities. First, we demonstrate that the magnitude 4 events with known source mechanisms can be used to calibrate the path ...

Dizhen xuebao, 2023 基于四川省威远地区密集流动台站从2019年12月1日至2020年6月30日期间收集到的42个ML3.0—4.5中小地震事件，采用Hypo2000定位法进行精定位，并利用HASH （Hardebeck & Shearer）法反演得到其中31次地震的震源机制解，之后利用阻尼区域应力反演方法计算了研究区的应力场参数。结果表明：中小地震主要分布在威远背斜南翼SSE向墨林场断层的两侧，震源深度集中在10 km以内，均为浅源地震；震源机制解类型以逆冲型为主，断层错动类型较为复杂，根据震源机制解结果 ...

Dizhen xuebao, 2021 震后应急工作中地震影响场的判定和快速给出较为合理的地震烈度分布图，是震后应急救援的重要依据，对于政府了解灾情、部署工作以及估算灾害损失都尤为重要，所以本文以此为研究目的，力求震后快速给出准确的地震烈度分布图。本文收集整理了河北地区中强地震的实际等震线图，将其与加入了震源机制解影响参数的烈度衰减关系计算得到的理论等震线图进行对比。结果显示：随着震级的增大，由衰减关系计算得到的等震线图与实际地震等震线图在高烈度区（≥Ⅶ度）相似度更高。另外，根据震后24小时内余震频度的空间变化，对极震区理论等震线修正后 ...
