After a brief discussion of the σ-hole concept and the significance of molecular electrostatic potentials in noncovalent interactions, we draw attention to some common misconceptions that are encountered in that context: (1) Since the electrostatic potential reflects the contributions of both the nuclei and the electrons, it cannot be assumed that negative potentials correspond to “electron-ric...

This paper describes an approach to identify suspected cybermob on social media. Many researches involve making predictions of group emotion on Internet (such as quantifying sentiment polarity), but this paper instead focuses on the origin of information diffusion, namely back to its makers and contributors. According our previous findings that have shown, at the level of Tieba’s contents, the ...

Infection is the commonest and the most serious problem in patients who survive the shock phase of major thermal injury. It is the most important cause of mortality and morbidity in burn patients. The present paper attempts to study the bacterial profile of burn wounds. One hundred and fifty patients admitted with burn injury were studied. Patients received routine resuscitation and local wound...

The notion of agent’s goals is crucial in negotiation dialogues. In fact, during a negotiation, each agent tries to make and to accept the offers which satisfy its own goals. Works on negotiation suppose that an agent has a set of fixed goals to pursue. However, it is not shown how the goals are computed and chosen by the agent. Moreover, these works handle one kind of goals: the ones that an a...

Laminar mixed convection of Aluminium oxide (Al2O3)–water nanofluid flow in an inclined annulus using a single-phase approach was numerically studied. Constant heat flux boundary conditions were applied on the inner and outer walls. All the thermophysical properties of nanofluid, such as, viscosity, heat capacity, thermal conductivity, and thermal expansion coefficient...

The KO(t)Bu-mediated annulation of acetonitrile with aldehyde was observed, in which the cleavage of four C(sp(3))-H bonds occurred and a total of eight new bonds were formed during the synthesis of substituted dihydropyridinones in the presence of peroxide. Furthermore, dihydropyridinones have been transformed into pyridinones using KO(t)Bu in DMSO.

Statistical machine learning focuses on non-parametric models that learn the minimum necessary to perform the targeted discrimination. For instance, in a binary classification problem, SVMs will only use the examples located within a boundary margin between the two classes to compute the optimal separation. However, one can consider other discrimination settings that use the entirety of the dat...

There is ample evidence that emotions affect performance. Positive emotions can improve performance, while negative ones can diminish it. For example, the fears induced by the possibility of failure or of negative evaluations have physiological consequences (shaking, loss of concentration) that may impair performance in sports, on stage, or at school. There is also ample evidence that individua...

Recurrent Neural Networks (RNNs) are designed to handle sequential data but suffer from vanishing or exploding gradients. Recent work on Unitary Recurrent Neural Networks (uRNNs) have been used to address this issue and in some cases, exceed the capabilities of Long Short-Term Memory networks (LSTMs). We propose a simpler and novel update scheme to maintain orthogonal recurrent weight matrices ...

Do you like science fiction? Have you heard of, or are you even a fan of, the famous “Star Wars” series? To summarize, there are rebels, emperors, princesses, robots, and many more fabulous creatures. There is also a power source called “The Force.” It is used by the Jedi (the good ones) but also by the dark side (the evil ones). Only the dark side uses the destructive power of “The Force,” whi...
