Essays in dynamic pricing, channel control and channel competition by Song, Boqian

“…In particular, we show the existence of a unique sub-game perfect normalized Nash equilibrium where both sellers share identical shadow prices on the constrained strategy space. We find that, at any given state, the normalized Nash equilibrium is uniquely determined by the reservation costs of distribution channels. …”

Bio-modification of sand for cement grouting by Ng, Samuel Joel Rui Ming

“…This was answered by comparing the compressive strength of lean concrete cubes made with MICP treated sea sand to lean concrete made with untreated river sand. Research was done to find its economic cost. From the results obtained, it was found that as the amount of calcium carbonate increased, the strength of the lean concrete, in other words, grout, also increased with an optimum treatment run of 2 times. …”

Toward a neuroscientific understanding of play: a dimensional coding framework for analyzing infant–adult play patterns by Neale, Dave, Clackson, Kaili, Georgieva, Stanimira, Dedetas, Hatice, Scarpate, Melissa, Wass, Sam, Leong, Victoria

“…Here, we illustrate the sensitivity and utility of the proposed coding framework using two contrasting dyadic corpora (N = 5) of mother-infant object-oriented interactions during experimental conditions that were either non-conducive (Condition 1) or conducive (Condition 2) to the emergence of playful behavior. We find that the framework accurately identifies the modal form of social interaction as being either non-playful (Condition 1) or playful (Condition 2), and further provides useful insights about differences in the quality of social interaction and temporal synchronicity within the dyad. …”

Electronic structure of topological quantum materials probed by angle-resolved photoelectron spectroscopy by Schröter, N

“…Additionally, our characterization of its bulk electronic structure finds a large imbalance between the electron and hole carrier densities, which challenges the previously assumed scenario of perfect carrier compensation as the origin of the XMR.…”

Lithological controls of the Mg isotope composition of the Lena River across seasons and its impact on the annual isotope flux to the Arctic Ocean by Mavromatis, V, Porcelli, D, Andersson, PS, Korets, MA, Pokrovsky, OS

“…In general, we did not find evidence of any statistically significant (p < 0.05) correlation between δ²⁶Mg and main physico-geographical parameters of the river watersheds (temperature, permafrost, type of vegetation). …”

An epigenetic analysis of planarian stem cells by Dattani, A

“…Bivalent histone modifications in mammalian embryonic and germline stem cells enable transcriptional poising of genes, and consistent with this we find that bivalent genes in planarian NBs are marked by paused RNA Pol II at the promoter-proximal region. …”

Development of an integrated scheduling model for handling equipment in automated port container terminals by Sadeghian, Syed Hamidreza

“…In addition, results proved that the modified meta-heuristic algorithm is able to find near optimal solutions and on average, the solutions found by the GA algorithm are only 0.2% worse than the optimal solutions and in the worst case in the test cases this difference is 2.3% which is acceptable. …”

Combining laser frequency combs and iodine cell calibration techniques for Doppler detection of exoplanets by Cahoy, K., Fischer, D., Spronck, J., Demille, D.

“…The smaller mass and longer period of true Earth analogues require the ability to detect a reflex velocity of ~10 cm/s over long time periods. Currently, typical astronomical spectrographs calibrate using either Iodine absorptive cells or Thorium Argon lamps and achieve ~10 m/s precision, with the most stable spectrographs pushing down to ~2 m/s. …”

“…Tests aimed to assess the performance of this kind of detectors in high-irradiation conditions, analogous to the ones foreseen for the coming years at the Large Hadron Collider experiments, were performed, and demonstrate a performance basically similar to the one obtained with the gas mixtures currently in use, based on tetrafluoroethane, which is being progressively phased out for its possible contribution to the greenhouse effect. Long term aging tests are also being carried out, with the goal to demonstrate the possibility of using these eco-friendly gas mixtures during the whole High Luminosity phase of the Large Hadron Collider.…”
