Prevention is better than cure. This simple rule applies to any disease and is especially valuable when symptoms are not properly acknowledged.
We will describe crucial symptoms that might occur one month (or even earlier) before a heart attack. You don’t need to become a total hypochondriac, but a bit of health awareness never hurt anybody. Pay close attention in case you are at risk. Several often-missed indicators are listed at the end of the article. health, medicine, science, health, medicine, science, health, science, health, science.
A web page pretending to offer an official application from PayPal is currently spreading a new variant of Nemty ransomware to unsuspecting users.
It appears that the operators of this file-encrypting malware are trying various distribution channels as it was recently observed as a payload from the RIG exploit kit (EK).
After what has been a summer of “crippling ransomware attacks,” there has now been some respite courtesy of the city of New Bedford, Massachusetts, which has proven that the playing field can be levelled. The city was hit back in July, with its data held hostage, ransomed for more than $5 million in bitcoin. But as the attackers waited for their payment, the city’s law enforcement agencies and technology teams had other ideas.
No types of organisations are immune from these types of attacks these days,” Mayor Jon Mitchell told reporters. The city government, he said, had been taking steps to strengthen our defences—but any network is only one keyword click away from an attack. Thankfully, he acknowledged, “the attack could have been much worse.” It hit on the July 4 holiday when many systems were shut down.
“The attack was a variant of the RYUK virus,” Mitchell confirmed. “The victim needs to make a ransom payment to acquire the decryption key from the attacker.” The attack did not affect all systems or disrupt all services, and on the return to work on July 5, the city kept systems turned off as they isolated the attack.
As AI gets better at performing routine tasks traditionally done by humans, only stressful ones will be left. The work experience could suffer.
Abstract: In this review-article, we discuss the consequences of the introduction of a quantum of time tau_0 in the formalism of non-relativistic quantum mechanics (QM) by referring ourselves in particular to the theory of the “chronon” as proposed by P.Caldirola. Such an interesting “finite difference” theory, forwards —at the classical level— a solution for the motion of a particle endowed with a non-negligible charge in an external electromagnetic field, overcoming all the known difficulties met by Abraham-Lorentz’s and Dirac’s approaches (and even allowing a clear answer to the question whether a free falling charged particle does or does not emit radiation), and —at the quantum level— yields a remarkable mass spectrum for leptons. After having briefly reviewed Caldirola’s approach, we compare one another the new Schroedinger, Heisenberg and density-operator (Liouville-von Neumann) pictures resulting from it. Moreover, for each representation, three (retarded, symmetric and advanced) formulations are possible, which refer either to times t and t-tau_0, or to times t-tau_0/2 and t+tau_0/2, or to times t and t+tau_0, respectively. It is interesting to notice that, e.g., the “retarded” QM does naturally appear to describe QM with friction, i.e., to describe dissipative quantum systems (like a particle moving in an absorbing medium). In this sense, discretized QM is much richer than the ordinary one. When the density matrix formalism is applied to the solution of the measurement problem in QM, very interesting results are met, so as a natural explication of “decoherence”.

PDF | The introduction of quantum of time, called Chronon, and its consequences for the electron in quantum and classical physics is presented. The most impressive achievement related to the introduction of the chronon hypothesis in the realm of QM comes from the description of a…
Scientists measure precise proton radius to help resolve decade-old puzzle, resulting in York University research that confirms protons are smaller than expected.
York University researchers have made a precise measurement of the size of the proton – a crucial step towards solving a mystery that has preoccupied scientists around the world for the past decade.
Scientists thought they knew the size of the proton, but that changed in 2010 when a team of physicists measured the proton-radius value to be four percent smaller than expected, which confused the scientific community. Since then, the world’s physicists have been scrambling to resolve the proton-radius puzzle – the inconsistency between these two proton-radius values. This puzzle is an important unsolved problem in fundamental physics today.
A gene that appeared sometime after humans began processing their food seems to protect some people from type 2 diabetes.
Saturn may be doing a little electromagnetic shimmy and twist which has been throwing off attempts by scientists to determine how long it takes for the planet to rotate on its axis, according to a new study.
Discovering the length of a day on any planet seems like a straightforward task: Find some feature on the planet and clock it as it rotates around once. Or, if it’s a gas giant like Jupiter, which has no solid surface features, scientists can listen for periodic modulations in the intensity of radio signals created within the planet’s rotating magnetic field.
And then there is Saturn, which for decades has defied attempts to pin down out its exact rotation period. Now a new study in AGU’s Journal of Geophysical Research: Space Physics may have finally unveiled the gas giant’s trick for hiding its rotation, and provide the key to giving up its secret.
