SEISMICITY NEAR THE SHIKANO AND YOSHIOKA FAULTS
No full textHypocenters and focal mechanisms for the earthquakes, which occurred near the Shikanoand Yoshioka faults have been determined using the data from the recently introduced telemeteringobservation system of the Tottori Microearthquake Observatory. Hypocenters of 32 events havebeen located, whose errors are less than 500 m in epicenter and 2 km in focal depth.The earthquake foci are distributed along the trace of the Shikano fault and along the lineextending northward from the western end of the fault. Along the Yoshioka fault are noearthquakes. Concentrated regions of foci are distributed at every about 3 km. The activityaround the western part of the Shikano fault is such that the isolated large shocks with magnitudegreater than 2 occurs successively. This feature is also seen in the activity in 1974. On the otherhand, ultra-microearthquakes tend to cluster in a small region along the east part of the fault.The size of the region where the microearthquakes have a common type of focal-mechanismis about 5 km or more in diameter. This may reflect a block-structure of the crust.Hypocenters and focal mechanisms for the earthquakes, which occurred near the Shikanoand Yoshioka faults have been determined using the data from the recently introduced telemeteringobservation system of the Tottori Microearthquake Observatory.

TEMPORAL VARIATIONS IN WATER QUALITY AND TEMPERATURE AT HOT OR MINERAL SPRINGS BEFORE AND AFTER SOME EARTHQUAKE OCCURRENCES NEAR THE BORDER OF TOTTORI AND SHIMANE PREFECTURES (1989-1991)
No full textTemporal variations in water quality and temperature at 5 hot or mineral springs (Tamatsukuri, Yuda, Sekigane, Yoshioka and Yudani) in Tottori and Shimane Prefectures have been observed for geochemical research for earthquake prediction.Since October, 1989, the seismicity have been active near the border of Tottori and Shimane Prefectures.We carefully estimated the contribution of meteorological factors and earthquakes to the water quality and temperature and found the water quality at the Yoshioka hot spring and water temperature at the Yudani hot spring are sensitive to earthquake occurrences.Especially at Yoshioka hot spring, the C1￣concentration was anomalously increased just before the earthquake(M 5.9) on August 28, 1991 in the eastern part of Shimane Prefecture.We conclude that measurement of water quality and temperature at a carefully chosen hot or mineral spring should give information useful for earthquake prediction.Temporal variations in water quality and temperature at 5 hot or mineral springs (Tamatsukuri, Yuda, Sekigane, Yoshioka and Yudani) in Tottori and Shimane Prefectures have been observed for geochemical research for earthquake prediction.Since October, 1989, the seismicity have been active near the border of Tottori and Shimane Prefectures.We carefully estimated the contribution of meteorological factors and earthquakes to the water quality and temperature and found the water quality at the Yoshioka hot spring and water temperature at the Yudani hot spring are sensitive to earthquake occurrences.Especially at Yoshioka hot spring, the C1￣concentration was anomalously increased just before the earthquake(M 5.9) on August 28, 1991 in the eastern part of Shimane Prefecture.We conclude that measurement of water quality and temperature at a carefully chosen hot or mineral spring should give information useful for earthquake prediction
Encoding and Replay of Dynamic Attractors with Multiple Frequencies: Analysis of a STDP Based Learning Rule
No full textAfter learning, each encoded oscillatory spatio-temporal pattern who satisfy the stability condition forms a dynamical attractor, such that, when the state of the system falls in the basin of attraction of one such dynamical attractor, it is recovered with the same encoded phase relationship among units. Here we extend the analysis introduced in our previous work, to the case of distributed frequencies, and we study the relation between stability of multiple frequencies and the shape of the learning window. The stability of the dynamical attractors play a critical role. We show that imprinting into the network a spatio-temporal pattern with a new frequency of oscillation can destroy the stability of patterns encoded with different frequency of oscillation. The system is studied both with numerical simulations, and analytically in terms of order parameters when a finite number of dynamic attractors are encoded into the network in the thermodynamic limit
Spatiotemporal learning in analog neural networks using spike-timing-dependent synaptic plasticity
No full textIncorporating the spike-timing-dependent synaptic plasticity (STDP) into a learning rule, we study spatiotemporal learning in analog neural networks. First, we study learning of a finite number of periodic spatiotemporal patterns by deriving the dynamics of the order parameters. When a pattern is retrieved successfully, the order parameters exhibit periodic oscillation. Analyzing this oscillation of the order parameters, we elucidate the relation of the STDP time window to the properties of the retrieval state; the phase of the Fourier transform of the STDP time window determines the retrieval frequency and the time average of the STDP time window crucially affects the storage capacity. We also evaluate the stability of the order parameter oscillation and identify the retrieval state that is stable in single-pattern learning but unstable in multiple-pattern learning even when the retrieval state is independent of a pattern number. To examine the further applicability of the STDP-based learning rule, we also study learning of nonperiodic spatiotemporal Poisson patterns. Our numerical simulations demonstrate that the Poisson patterns are memorized successfully not only in analog neural networks but also in spiking neural networks
Platelet rich plasma and orthopedics: Why, when, and how
No full textIn present practice, orthopedic and sports medicine is making a great effort in promoting the use of minimally invasive techniques aimed at arresting or slowing down the aging and degeneration of several tissues. The scientific community has been developing new areas of research that have fuelled the emergence of regenerative medicine and tissue engineering bringing into the spotlight treatments such as those based on stem cells and platelet rich plasma (PRP)
