The Earthling's Secret Weapon: Cumulative Culture and the Singularity

Neil Levy

...power alone, without the scaffolding of culture, are unlikely to outcompete us intellectually. There is, however, nothing to prevent AIs from having, and taking advantage of, a capacity for culture. AIs with such a capacity may have intellectual powers greater than ours currently are, but the collective deliberation that underlies the power of cumulative culture is more powerful when there is sufficient diversity among the deliberators. This fact will give AIs...

...ressure.Chitosan-gelatin scaffolds were fabricated by vacuum freeze drying. Keratinocytes and fibroblasts were seeding on scaffolds to form systems as: keratinocytes monoculture (KM), ﬁbroblasts monoculture (FM), co-culture of keratinocytes and ﬁbroblasts (KM&FM). Systems was treated with 3.4 kPa pressure for 1 day, systems without pressure was considered as control groups. The mRNA expression and protein secretion o...

TWO-PHOTON FLUORESCENCE EXCITATION CROSS-SECTIONS OF PHOTOSENSITIZER THIOXANTHONE TO FABRICATE CELL SCAFFOLD FOR BIOMEDICAL APPLICATIONS

...itizer to fabricate cell scaffold in Ethoxylated Bis Phenol A
Dimethacrylate for tissue repair in the field of biomedical. Also Incident Laser Power Effects were analyzed and
found that the Fluorescence Intensity increases with increasing Incident Laser Power, Io, and the emitted fluorescence
obeys the square-law dependences. Also when the Photo-Sensitizer was excited at different wavelengths (800nm,
400nm), it was found that Fluore...

CHARACTERISTICS AND EFFICACY OF ULTRAFAST LASER PULSES FOR BIOMEDICAL APPLICATIONS

...f three dimensional cell scaffolds, femtosecond laser irradiation at 800nm was used for
biomedical applications. The femtosecond laser system was also used to fabricate a bricks and mortar structure in
keratin films to investigate skin structures for different cream absorption. The laser characterised here is Spectra
Physics, Hurricane X. This is a complex laser system consisting of a seed laser and a regenerative amplifier. It is

Ce-doped Nanobioactive Glass/ Collagen/ Chitosan Composite Scaffolds: Biocompatibility with Normal Rabbit’s Osteoblast Cells and Anticancer Activity Test

Hanan Fathy Hammouda¹, Mohammad Mahmoud Farag²*, Mervet M.F. El Deftar³, Mohamed Abdel-Gabbar⁴, Basant M. Mohamed⁴

...agen/chitosan composites scaffolds with osteoblast mineralization of normal rabbit bone marrow mesenchymal stem cells (rBM-MSCs) and cancer osteosarcoma cells. The non-cellular in vitro bioactivity test was performed in simulated body fluids for periods 1, 3, 10, 20 and 30 d by measuring the calcium and phosphate ion concentrations by SEM/EDX analysis. While, the bioactivity of expanded and differentiated osteoblast cells derived from isolated rBM-MSCs ...

Synthesis and Characterization of Porous β-Calcium Pyrophosphate Bone Scaffold Derived from Avian Eggshell

Ali Ghazi Atiyah¹*, Nadia Hameed Rija Al-Falahi² and Ghazi Atiya Zarraq³

...rophosphate (β-CPP) scaffold, a type of calcium phosphate-based biomaterials, can be used in orthopedic and dental surgery. This study focused on the synthesis of the β-CPP bone scaffold from waste biomaterials such as avian eggshell, which consider a natural source of calcium precursor. The β-CPP powder was prepared by a wet precipitation process using calcination temperature 1200 ºC for 2 h, then the

The Restorative Effect of Titanium Dioxide Nanoparticles Synthesized with Origanum vulgare L., Carvacrol, Hypericum perforatum L., and Hypericin Loaded in Calcium Alginate Scaffold on Staphylococcus aureus-Infected Ulcers in Diabetic Rats

...um, and calcium alginate scaffold-loadable calcium alginate on infected wounds with Staphylococcus aureus was investigated in diabetic rats. Eight groups of 12 rats in any group were diabetic by intraperitoneal injection of alloxan. After the rats were anesthetized, 2cm2 wounds were created and inoculated with bacterial suspension of S. aureus (ATCC 12600) equivalent to the 0.5 MacFarland tube. The hydroalcoholic extracts of Origanum vulgare, Hypericum perfora...
