Bifurcating reactions: distribution of products from energy distribution in a shared reactive mode

Reactive Mode Composition Factor (RMCF) analysis is a powerful tool to forecast the product distribution of bifurcating reactions through analysis of the kinetic energy distribution within the first transition state traversed by the reacting system.

The European Economic Constitution after the PSPP Judgment: Towards Integrative Liberalism?

This article argues that the PSPP judgment effectively buries the era of financial liberalism, which has dominated the European economic constitution for decades. It raises the curtain on a new political paradigm, which I call “integrative liberalism”. Whereas the financial crisis put financial liberalism under strain, the development since then has been contradictory, torn between state intervention and market liberalism, focused above all on buying time rather than finding a new constitutional equilibrium. Now, together with the measures adopted in response to COVID-19, the PSPP judgment paves the way for profound change. Integrative liberalism is characterized by an overall shift from the market to the state, mitigating the post-crisis insistence on austerity and conditionality. Contrary to the embedded liberalism of the post-war era, integrative liberalism operates in a corrective and reactive mode with a focus on goals and principles, lacking the emphasis on long-term planning. Like every political paradigm, integrative liberalism ushers in a new understanding of the law. It puts the emphasis on context instead of discipline, and it elevates the proportionality principle. If integrative liberalism is to succeed, however, the democratic legitimacy of the Eurosystem and its independence require serious reconsideration.

CuO-Ga2O3 Thin Films as a Gas-Sensitive Material for Acetone Detection

The p-n heterostructures of CuO-Ga2O3 obtained by magnetron sputtering technology in a fully reactive mode (deposition in pure oxygen) were tested under exposure to low acetone concentrations. After deposition, the films were annealed at previously confirmed conditions (400 °C/4 h/synthetic air) and further investigated by utilization of X-ray diffraction (XRD), X-ray reflectivity (XRR), energy-dispersive X-ray spectroscopy (EDS). The gas-sensing behavior was tested in the air/acetone atmosphere in the range of 0.1–1.25 ppm, as well as at various relative humidity (RH) levels (10–85%). The highest responses were obtained for samples based on the CuO-Ga2O3 (4% at. Ga).

Synthesis, Microstructural, and Mechano-Tribological Properties of Self-Lubricating W-S-C(H) Thin Films Deposited by Different RF Magnetron Sputtering Procedures

Carbon-alloyed transition metal dichalcogenide (TMD) coatings have great potential for providing a good tribological response in diverse operating environments. There are different ways to synthesize these coatings by magnetron sputtering, with no clear indication of the best possible route for potential upscaling. In this study, tungsten-sulfur-carbon (W-S-C) coatings were deposited by radio frequency (RF) magnetron sputtering via four different methods. All coatings were sub-stoichiometric in terms of the S/W ratio, with the bombardment of the growing film with backscattered Ar neutrals being the main mechanism governing the S/W ratio. The crystallinity of the films was dependent on the C and S contents. X-ray photoelectron spectroscopy (XPS) revealed W-S and W-C bonding in all coatings. Raman spectroscopy showed the presence of an a-C phase with predominant sp2 bonding. The hardness of the coatings may be related to the C content and the S/W ratio. A friction coefficient of 0.06–0.08 was achieved during sliding in ambient air by the coatings deposited in non-reactive mode with optimal C contents. The results indicate that sputtering in non-reactive mode should be the method of choice for synthesis of these coatings.

A new look at the question of the bilingual advantage

Bilingualism has been associated with age-related cognitive advantage. It is important to study cognitive control mechanisms to better understand this phenomenon. We sought to examine proactive and reactive control, as measured by fast and slow responses, respectively. The neural underpinnings of these modes of control were studied in rigorously matched elderly monolinguals and bilinguals, using fMRI performance on a Simon task. The results indicate that bilinguals performed efficiently in proactive mode, as more activation and connectivity were observed in the monolinguals. On the other hand, the monolinguals functioned more efficiently in reactive mode, recruiting fewer brain areas than the bilinguals. These results suggest that bilinguals’ function effortlessly and economically in proactive mode, which is preserved through lifelong use of languages, whereas monolinguals are efficient in reactive mode, which they use more often as a consequence of aging. Thus, frequent use in daily life contributes to efficient functioning in the respective mode of control.

Reactive mode composition factor analysis of transition states: the case of coupled electron–proton transfers

The kinetic energy distribution in the reactive mode in transition states correlates the asynchronicity of CPET with relative kinetic isotope effects.

Trust-Based Impedance Control Strategy for Human-Robot Cooperative Manipulation

A trust-based switching impedance control strategy for human-robot cooperative manipulation is proposed. The robot behavior switches between the proactive and reactive modes based on the estimated trust of human in robot. The robot estimates the human desired trajectory. A history-based probabilistic trust model for human-robot cooperative manipulation tasks is proposed. Trust is modeled as a dynamic Bayesian network. In the proactive mode, the robot estimates the human desired trajectory and plans accordingly while in the reactive mode, the robot only reacts to the human input. A simulation of the trust-based switching impedance control strategy is presented.
