A new formal theory DT of truth extending PA is introduced, whose language is that of PA together with one new unary predicate symbol T (x), for truth applied to Gödel numbers of suitable sentences in the extended language. Falsity of x , F(x), is defined as truth of the negation of x ; then, the formula D(x) expressing that x is the number of a determinate meaningful sentence is defined as the...

IN 1925, COLLIP AND CLARK (the same Collip who had extracted insulin from the pancreas several years earlier) infused crude parathyroid extracts into dogs and observed a decrease in systemic blood pressure (5). Thus began an interest in the putative regulation of excitable cells by parathyroid hormone (PTH) that persisted for over 60 years (4). We now know that parathyroid hormone-related prote...

We investigated the effects of a γ-tocopherol–rich mixture of tocopherols (γ-TmT, containing 57% γ-T, 24% δ-T, and 13% α-T) on colon carcinogenesis in azoxymethane (AOM)/dextran sulfate sodium (DSS)–treated mice. In experiment 1, 6-week-old male CF-1 mice were given a dose of AOM (10 mg/kg body weight, i.p.), and 1 week later, 1.5% DSS in drinking water for 1 week. The mice were maintained on e...

When preschoolers count to check their arithmetic predictions, their counts are better than when they simply count a set of items on count-only tasks. This is so even for 2 1/2and 3-year-olds dealing with small values. Such results lend support to the view that learning about verbal counting benefits from a nonverbal count-arithmetic system and challenge theories that place understanding of ver...

Accumulation of sulfolipids associated with markedly elevated levels of glycolipid sulfotransferase activities was previously demonstrated in human renal cell carcinoma cells. To explore the regulation mechanisms of sulfoglycolipid synthesis in renal cancer, effects of various growth factors on the metabolic enzymes of sulfoglycolipids were investigated by using a human renal cell carcinoma cel...

This paper outlines the design and implementation of the launching and landing of an unmanned aerial vehicle (UAV) onto an unmanned surface vehicle (USV). The US Navy and Northrop Grumman’s X-47B drone have just recently achieved the first autonomous landing of an aircraft onto an aircraft carrier, but it came at the price tag of over one billion U.S. dollars. The authors of this paper will cre...
