Learning-by-Doing in the Newsvendor Problem - A Laboratory Investigation of the Role of Experience and Feedback

Abstract: We investigate learning-by-doing in the newsvendor inventory problem. An earlier study observed that decision makers tend to anchor orders away from the expected profit maximizing order. We study enhancements to the learning environment suggested by the behavioral literature. Extended experience improves performance some but feedback enhancements do little. A manipulation with a strong positive effect constrains inventory policy to a standing order for multiple periods, precluding responses to short term fluctuations in demand. With experience, our newsvendors collectively achieve over 90% of expected profit potential. It turns out that this kind of hands-on learning is more effective than providing newsvendors with an upfront statistical analysis that includes the expected profitability of orders. The results speak to the kinds of training and decision support that might improve the performance of inventory decision makers.

Glomerular barrier behaves as an atomically precise bandpass filter in a sub-nanometre regime.

Abstract: The glomerulus can use its glycocalyx layer to precisely control renal clearance and tumour targeting of sub-nm gold nanoclusters with size differences of just a few atoms.

Highly Scalable, Atomically Thin WSe2 Grown via Metal–Organic Chemical Vapor Deposition

Abstract: Tungsten diselenide (WSe2) is a two-dimensional material that is of interest for next-generation electronic and optoelectronic devices due to its direct bandgap of 1.65 eV in the monolayer form and excellent transport properties. However, technologies based on this 2D material cannot be realized without a scalable synthesis process. Here, we demonstrate the first scalable synthesis of large-area, mono and few-layer WSe2 via metal–organic chemical vapor deposition using tungsten hexacarbonyl (W(CO)6) and dimethylselenium ((CH3)2Se). In addition to being intrinsically scalable, this technique allows for the precise control of the vapor-phase chemistry, which is unobtainable using more traditional oxide vaporization routes. We show that temperature, pressure, Se:W ratio, and substrate choice have a strong impact on the ensuing atomic layer structure, with optimized conditions yielding >8 μm size domains.

Measurement of the Z/γ* boson transverse momentum distribution in pp collisions at √s = 7 TeV with the ATLAS detector

Abstract: This paper describes a measurement of the Z/gamma* boson transverse momentum spectrum using ATLAS proton-proton collision data at a centre-of-mass energy of root s = 7TeV at the LHC. The measurement is performed in the Z/gamma* -> e(+)e(-) and Z/gamma* -> mu(+)mu(-) channels, using data corresponding to an integrated luminosity of 4.7 fb(-1). Normalized differential cross sections as a function of the Z/gamma* boson transverse momentum are measured for transverse momenta up to 800 GeV. The measurement is performed inclusively for Z/gamma* rapidities up to 2.4, as well as in three rapidity bins. The channel results are combined, compared to perturbative and resummed QCD calculations and used to constrain the parton shower parameters of Monte Carlo generators.
