Real-time prediction of Bitcoin bubble crashes

open access: yesPhysica A: Statistical Mechanics and its Applications, 2020
In the past decade, Bitcoin as an emerging asset class has gained widespread public attention because of their extraordinary returns in phases of extreme price growth and their unpredictable massive crashes. We apply the log-periodic power law singularity (LPPLS) confidence indicator as a diagnostic tool for identifying bubbles using the daily data on ...

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Crash Severity Prediction Using Two-Layer Ensemble Machine Learning Model for Proactive Emergency Management

open access: yesIEEE Access, 2020
Many unfortunate victims in road traffic crashes do not receive ideal treatment because their injury severity is not understood at an early stage. Swift crash severity prediction enables trauma and emergency centers to estimate the potential damage ...

The Nasdaq crash of April 2000: Yet another example of log-periodicity in a speculative bubble ending in a crash

open access: yes, 2000
The Nasdaq Composite fell another $\approx 10 %$ on Friday the 14'th of April 2000 signaling the end of a remarkable speculative high-tech bubble starting in spring 1997. The closing of the Nasdaq Composite at 3321 corresponds to a total loss of over 35%

Predicting Truck At-Fault Crashes Using Crash and Traffic Offence Data [PDF]

open access: yesThe Open Transportation Journal, 2018
Introduction:The number of truck-related injuries and deaths can be reduced by understanding the factors that contribute to the higher risk of truck-related crashes and violations. Truck drivers are at fault of more than 80% of all the truck crashes on Wyoming interstates, and the literature review indicated that in order to identify appropriate ...

Aggregate Crash Prediction Model Based on Gravity Model: Introducing Crash Risk Distribution Concept

open access: yesTransportation Engineering, 2023
Crash prediction models (CPMs) can be valuable for future transportation planning decisions. This study aims to develop CPMs based on the trip distribution step of the common four-step demand models. For this purpose, the Gravity Model is used. For model calibration, the frequency of severe crashes (including the total of fatal and injury crashes ...
