Black locust (Robinia pseudoacacia L.) is a tree species of high economic and ecological value, but is also considered to be highly invasive. Understanding the global potential distribution and ecological characteristics of this species is a prerequisite for its practical exploitation as a resource. Here, a maximum entropy modeling (MaxEnt) was used to simulate the potential distribution of thi...

A signature scheme constructed according to the hash-andsign paradigm—hash the message and then sign the hash, symbolically σ(H(M))—is no more secure than the hash function H against a collision-finding attack. Recent attacks on standard hash functions call the paradigm into question. It is well known that a simple modification of the hash-and-sign paradigm may replace the collision-resistant h...

in this article, we present the case of a 12-year-old female child who complained of bilateral temporal and frontal headache for 2 to 3 months with nausea and vomiting. physical examination revealed right-sided sixth cranial nerve palsy and papilledema in ophthalmoscopy. to find the cause of increased intracranial pressure, the patient underwent brain imaging and brain mri showed no abnormality...

We show a superpolynomial oracle separation between the power of adiabatic quantum computation with no sign problem and classical computation.
