Possibility to algorithmically check: yet another reason why current definitions have been selected in elementary mathematics

Why have Pneumocystis carinii trophozoites been ignored?

Why have serine/threonine/tyrosine kinases been evolutionarily selected in eukaryotic signaling cascades?

The signal transduction systems of eukaryotes are different from those of prokaryotes with respect to their structures and mechanisms. The main signal transduction system of prokaryotes called the two-component system (TCS) is a one-step phosphorelay system composed of a histidine kinase (HK) while the central signal transduction system of eukaryotes called the mitogen-activated protein kinase ...

Preinfarct angina and exercise: yet another reason to stay physically active.

In the past, angina has been considered something bad. Though I still maintain that any ischemia is something the heart should avoid if possible, several studies suggest that preinfarct angina paradoxically may have protective effects (1–7). Our group observed this phenomenon in the Thrombolysis In Myocardial Infarction (TIMI-4) (1) study and then in the TIMI-9 study (2). Preinfarct angina redu...

Patient page. Cigarette smoking and multiple sclerosis (MS): yet another reason to quit.

Even after many years of being studied, the cause of MS is still unknown. It is believed that the disease is probably triggered by a combination of factors that are inherited and are present in the environment. The most likely environmental factor seems to be a virus or other source of infection. However, a specific infection has not yet been identified. In this issue of Neurology, Riise and co...

Yet Another Visit to Paxos

This paper presents a modular introduction to crash-tolerant and Byzantine-tolerant protocols for reaching consensus that use the method introduced by the Paxos algorithm of Lamport and by the viewstamped replication algorithm of Oki and Liskov. The consensus protocol runs a sequence of epoch abstractions as governed by an epoch-change abstraction. Implementations of epoch and epoch-change that...
