results the mean age of the patients was 14.73 ± 2.3 (range 13-16) years. the most common symptom was cyclic dysmenorrhea. the vaginal septum was resected safely in all of the patients. the symptoms including cyclic dysmenorrhea and hematometra resolved after 3 months. conclusions hysteroscopic resection of the vaginal septum is an available, feasible, convenient, and effective tool in the mana...

An enhanced binding of an N -particle system interacting through a scalar bose field is investigated, where N ≥ 2. It is not assumed that this system has a ground state for a zero coupling. It is shown, however, that there exists a ground state for a sufficiently large values of coupling constants. When the coupling constant is sufficiently large, N particles are bound to each other by the scal...

Humans are going to delegate the rights of driving to the autonomous vehicles in near future. However, to fulfill this complicated task, there is a need for a mechanism, which enforces the autonomous vehicles to obey the road and social rules that have been practiced by well-behaved drivers. This task can be achieved by introducing social norms compliance mechanism in the autonomous vehicles. T...

What happens when machines become more intelligent than humans? One view is that this event will be followed by an explosion to evergreater levels of intelligence, as each generation of machines creates more intelligent machines in turn. This intelligence explosion is now often known as the ‘singularity’. The basic argument here was set out by the statistician I.J. Good in his 1965 article ‘Spe...

We provide a very general result that identifies the essential spectrum of broad classes of operators as exactly equal to the closure of the union of the spectra of suitable limits at infinity. Included is a new result on the essential spectra when potentials are asymptotic to isospectral tori. We also recover with a unified framework the HVZ theorem and Krein’s results on orthogonal polynomial...

We prove a HVZ theorem for a general class of no-pair Hamiltonians describing an atom or positively charged ion with several electrons in the presence of a classical external magnetic field. Moreover, we show that there exist infinitely many eigenvalues below the essential spectrum and that the corresponding eigenfunctions are exponentially localized. The novelty is that the electrostatic and m...

How do individuals who switch between opposing sides develop a sense of commitment to their new groups? Study 1 examined these dynamics in a live-action tag game known as Humans versus Zombies, in which players transitioned from being Human to being Zombie, thus turning against their former fellow Humans. Study 2 examined data from professional basketball players in the NBA who moved to a new t...

Joint activities are ubiquitous in the animal kingdom, but they differ substantially in their underlying psychological states. Humans attribute and share mental states with others in the so-called shared intentionality. Our hypothesis is that our closest nonhuman living relatives also attribute some psychological mechanisms such as perceptions and goals to others, but, unlike humans, they are n...

Emotive virtual agents are seen to be a valuable tool in various research domains, including human studies, training, entertainment, and medicine. However, systems that primarily focus on social-emotional agents are largely domain-focused, or require ample customization to make them usable. The importance of agents that display social emotions and behaviors is underscored by the use of social s...

Humans attend to social cues in order to understand and predict others’ behavior. Facial expressions and gaze direction provide valuable information to infer others’mental states and intentions. The present study examined the mechanism of gaze following in the context of participants’ expectations about successive action steps of an observed actor. We embedded a gaze-cueing manipulation within ...
