The longest (s,t)-path problem on supergrid graphs is known to be NP-complete.However, the complexity of this problem on supergrid graphs with or without holes is still unknown.In the past, we presented Bar Parts linear-time algorithms for solving the longest (s,t)-path problem on L-shaped and C-shaped supergrid graphs, which form subclasses of sup
Background: Interest in global health is rapidly increasing amongst US medical students.Many students aspire to Spurs incorporate global health into their future careers, while others seek international opportunities to better prepare themselves for domestic practice.US medical schools have begun responding to this burgeoning interest with varying
The study investigates rheological properties of dough and baking process made from flour obtained by milling grains from ancient 7.35/7GRV varieties of wheat (einkorn, emmer and spelt), compared to common wheat flour dough (Arkadia variety).The findings show that einkorn flour dough and emmer flour dough present poor tolerance to mechanical proces
Endosymbiont-bearing trypanosomatids have been considered excellent models for the study of cell evolution because the host protozoan co-evolves with an intracellular bacterium in a mutualistic relationship.Such protozoa inhabit a single invertebrate host during their entire life cycle and exhibit special characteristics that group them in a partic
According to semantic externalism, the meaning of some words and thus the content of some of our mental states is determined at least partly by features of the external world.For the first time, Putnam has tried to argue that accepting externalism leads to the rejection of skepticism about the external world.However, it is widely argued that this a
