Uncomputability and Physical Law by Lloyd, Seth

“…In particular, the form of the energy spectrum of quantum systems capable of universal computation is uncomputable: to answer whether a Hamiltonian system is gapped or gapless in a particular sector requires one to solve the Halting problem. Finally, the problem of determining the most concise expression of physical laws requires one to determine the algorithmic complexity of those laws, and so, the answer to this problem is uncomputable.…”

Within-host evolution of HIV-1 and the analysis of transmissible diversity by English, SE

“…<p>The central problem for researchers of HIV-1 evolution is explaining the apparent design of the virus for causing pandemic infection in humans: understanding how HIV-1 spreads is key to halting the pandemic. Current knowledge of how HIV-1 spreads from host to host is based upon experimental observation and indirect inferences informed by theory. …”

Recycled melanoma-secreted melanosomes regulate tumor-associated macrophage diversification by Parikh, Roma, Parikh, Shivang, Berzin, Daniella, Vaknine, Hananya, Ovadia, Shai, Likonen, Daniela, Greenberger, Shoshana, Scope, Alon, Elgavish, Sharona, Nevo, Yuval, Plaschkes, Inbar, Nizri, Eran, Kobiler, Oren, Maliah, Avishai, Zaremba, Laureen, Mohan, Vishnu, Sagi, Irit, Ashery-Padan, Ruth, Carmi, Yaron, Luxenburg, Chen, Hoheisel, Jörg D, Khaled, Mehdi, Levesque, Mitchell P, Levy, Carmit

“…Our findings suggest that interactions mediated by second-hand extracellular vesicles contribute to the formation of the metastatic niche, and that blocking the melanosome cues of macrophage diversification could be helpful in halting melanoma progression.…”

Simulation study of semiconductor thermoelectric power generator for waste heat recovery and energy harvesting by Chan, Murphy Kim Hua

“…One of the proven initiatives is to perform waste heat recovery using thermoelectric generators (TEGs) in wide variety of applications including space, solar photovoltaic, automotive, smelting and more. To understand key aspects of TEG performances such as power output and efficiency, the study of thermoelectric material with respect to applied temperature is also another important consideration. …”
