Detecting collusion on highway procurement

Económica, 2013
This paper proposes a procedure to detect collusion in asymmetric first-price procurement. The main objective is twofold. First, to provide a methodology to detect collusion using a structural approach, and second to apply the methodology to field data ...

Energy substrate used by workers of leaf-cutting ants during nest excavation

Revista Brasileira de Entomologia, 2013
Energy substrate used by workers of leaf-cutting ants during nest excavation. In this study we aimed to ascertain whether leaf-cutting ant workers lose body reserves (fat or sugars) as a function of nest excavation.

A Comment on "Cycles and Instability in a Rock-Paper-Scissors Population Game: A Continuous Time Experiment" [PDF]

, 2013
The authors (Cason, Friedman and Hopkins, Reviews of Economics Studies, 2014) claimed a result that the treatments (using simultaneous matching in discrete time) replicate previous results that exhibit weak or no cycles.

Hadronic light-by-light scattering in the muon g-2: impact of proposed measurements of the (pi^0 -> gamma gamma) decay width and the (gamma^* gamma -> pi^0) transition form factor with the KLOE-2 experiment

, 2012
We discuss, how planned measurements at KLOE-2 of the (pi^0 -> gamma gamma) decay width and the (gamma^* gamma -> pi^0) transition form factor can improve estimates for the numerically dominant pion-exchange contribution to hadronic light-by-light ...

Analysis of the immunomodulatory properties of mycobacterium cell wall fraction on the cytokine production of peripheral blood mononuclear cells of healthy dogs

Veterinary Dermatology, Volume 35, Issue 6, Page 595-604, December 2024.
Background – Mycobacterium cell wall fraction (MCWF) is derived from nonpathogenic Mycobacterium phlei and is used as an immunomodulatory compound in clinical practice, yet its mode‐of‐action requires further research. Objective – To evaluate the host response to MCWF in canine peripheral blood mononuclear cells (PBMCs) by using enzyme‐linked ...

Eine DNA‐Polymerase‐Variante erkennt den epigenetischen Marker 5‐Methylcytosin durch erhöhten Fehleinbau

Angewandte Chemie, Volume 136, Issue 48, November 25, 2024.
Entwicklung einer DNA‐Polymerase aus Thermus aquaticus, die methylierte von unmethylierter DNA durch einen erhöhten Fehleinbau gegenüber 5‐Methylcytosin (5 mC) während der DNA‐Synthese unterscheidet. Durch die Erzeugung von 5 mC‐abhängigen Mutationssignaturen im PCR‐Produkt ist das Enzym in der Lage, methylierte Stellen zu erkennen und ermöglicht den ...

Collision geometry fluctuations and triangular flow in heavy-ion collisions

, 2010
We introduce the concepts of participant triangularity and triangular flow in heavy-ion collisions, analogous to the definitions of participant eccentricity and elliptic flow.

A DNA Polymerase Variant Senses the Epigenetic Marker 5‐Methylcytosine by Increased Misincorporation

Angewandte Chemie International Edition, Volume 63, Issue 48, November 25, 2024.
Engineering of a Thermus aquaticus DNA polymerase that distinguishes methylated from unmethylated DNA by increased misincorporation opposite 5‐methylcytosine (5 mC) during DNA synthesis. By generating 5 mC‐dependent mutation signatures in the PCR product, the enzyme is able to sense methylated sites and allows direct detection by reading elevated error

Effect of the momentum dependence of nuclear symmetry potential on pion-/pion+ ratio in heavy-ion collisions

, 2011
In the framework of the isospin-dependent Boltzmann-Uehling-Uhlenbeck transport model, effect of the momentum dependence of nuclear symmetry potential on pion-/pion+ ratio in the neutron-rich reaction 132Sn+124Sn at a beam energy of 400 MeV/nucleon is ...

Short‐term ozone exposure and cancer mortality in Brazil: A nationwide case‐crossover study

International Journal of Cancer, Volume 155, Issue 10, Page 1731-1740, 15 November 2024.
What's new? Ground‐level exposure to ozone (O3) triggers inflammatory responses and oxidative stress, which are involved in pathways underlying cancer progression. The impact of O3 exposure on cancer mortality, however, remains unknown. Here, the authors assessed site‐specific cancer mortality in the context of short‐term exposure to elevated O3 ...
