IN: Is it true that is ejection fraction the same as stroke volume?

The EF of the left heart, known as the left ventricular ejection fraction (LVEF), is calculated by dividing the volume of blood pumped from the left ventricle per beat (stroke volume) by the volume of blood collected in the left ventricle at the end of diastolic filling (end-diastolic volume). LVEF is an indicator of the effectiveness of pumping into the systemic circulation. The EF of the right heart, or right ventricular ejection fraction (RVEF), is a measure of the efficiency of pumping into the pulmonary circulation. A heart which cannot pump sufficient blood to meet the body's requirements (i.e., heart failure) will often, but not invariably, have a reduced ventricular ejection fraction.

IN: Is it true that can you remote play ps3 games on vita?

Remote Play is a feature of Sony video game consoles that allows the PlayStation 3 and PlayStation 4 to transmit its video and audio output to a PlayStation Portable or PlayStation Vita. Similar functionality is provided on Nintendo's Wii U console, using the Off-TV Play function. This feature essentially allows compatible home console games to be played on the handheld. In 2014, it was expanded to include the use of PlayStation TV, Xperia smartphones and tablets (Z2 and later), and PlayStation Now. In 2016, it was expanded to Microsoft Windows PCs and macOS.

OUT: yes

IN: Is it true that can a dog get pregnant by a coyote?

A coydog (sometimes called dogote) is a canid hybrid resulting from a mating between a coyote and a dog. The term is sometimes mistakenly used for coywolves, which are common in northeast North America, whereas true coydogs are only occasionally found in the wild. This is due to the mating cycles of dogs and coyotes not coinciding, and coyotes are usually antagonistic towards dogs, with even captive specimens having shown reluctance to mate with them.

OUT: yes

IN: Is it true that is it legal to punch the back of the head in boxing?

In general, boxers are prohibited from hitting below the belt, holding, tripping, pushing, biting, or spitting. The boxer's shorts are raised so the opponent is not allowed to hit to the groin area with intent to cause pain or injury. Failure to abide by the former may result in a foul. They also are prohibited from kicking, head-butting, or hitting with any part of the arm other than the knuckles of a closed fist (including hitting with the elbow, shoulder or forearm, as well as with open gloves, the wrist, the inside, back or side of the hand). They are prohibited as well from hitting the back, back of the head or neck (called a ''rabbit-punch'') or the kidneys. They are prohibited from holding the ropes for support when punching, holding an opponent while punching, or ducking below the belt of their opponent (dropping below the waist of your opponent, no matter the distance between).
