Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT We examine the new energetic plasticizer 3‐(2‐(2‐(2‐azidoethoxy)ethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG3N3), three reference compounds (BDNPA/F, Bu‐NENA, and DNDA‐57), and a plasticizer‐free control in a fixed HMX/GAP composite. NFPEG3N3 provides the strongest low‐temperature properties, yielding the lowest formulation glass transition ...

Coopetition in for-profit and non-profit organizations - micro level
Management, 2019 A situation in which appears at the same time a competition and cooperation between the subjects is defined as a coopetition. First of all it is considered at the mezo level – between the companies, but it can be analysed at the micro level – inside the ...

What Drives Differences in Management Practices?
The American Economic Review, 2019 Partnering with the US Census Bureau, we implement a new survey of “structured” management practices in two waves of 35,000 manufacturing plants in 2010 and 2015.

The role of identification in data‐driven policy iteration: A system theoretic study
International Journal of Robust and Nonlinear Control, EarlyView.Abstract The goal of this article is to study fundamental mechanisms behind so‐called indirect and direct data‐driven control for unknown systems. Specifically, we consider policy iteration applied to the linear quadratic regulator problem. Two iterative procedures, where data collected from the system are repeatedly used to compute new estimates of ...

Heterogeneous effect of exchange rates on firms’ exports: Role of labor intensity
Central Bank Review, 2023 Using an extensive firm-level database that combines balance sheet information, social security registry and customs data, we examine whether the relationship between the exchange rate and exports change with the degree of labor-intensity of production ...

Thermal transport of the XXZ chain in a magnetic field
, 2005 We study the heat conduction of the spin-1/2 XXZ chain in finite magnetic fields where magnetothermal effects arise. Due to the integrability of this model, all transport coefficients diverge, signaled by finite Drude weights. Using exact diagonalization

Seismic performance evaluation of a century‐old RC columns for railway's structural concrete
Structural Concrete, EarlyView.Abstract Since the Great Kanto Earthquake of 1923 in Japan, reinforced concrete (RC) has been adopted for railway bridge piers, and some of these structures, now over 100 years old, continue to support transportation in the capital city of Tokyo. Evaluating the seismic performance of these few remaining RC structures has become an urgent issue. Because

Deformed Minkowski spaces: clasification and properties
, 1995 Using general but simple covariance arguments, we classify the `quantum' Minkowski spaces for dimensionless deformation parameters. This requires a previous analysis of the associated Lorentz groups, which reproduces a previous classification by ...

Integrative Zoology, EarlyView.18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐
