The interactive governance theory postulates that the governability of a fishery system depends on the governing capacity, and the overall quality of the system to be governed. The elements making the fisheries more or less governable correspond to the diversity, complexity, dynamics, and scale of the natural and social systems that are being governed and the governing system. To date, the extent to which technological development affects these properties, and the fisheries governability, has not been evaluated. This paper presents a novel conceptualization of "technological entropy", linking the concept of entropy with technological innovation happening across fisheries. It further discusses the relationship between technological entropy and governability of fishery systems and illustrates it using examples from Newfoundland fisheries. The paper argues that technological entropy creates new challenges for fisheries governance by influencing fishers' decisions and adding demands on the governing capacity. Assessing how technologies fit into the fisheries governability framework can, therefore, help inform governing actions towards securing sustainable fisheries.

Owing to its abundant manganese source, high operating voltage, and good ionic diffusivity attributed to its 3D Li-ion diffusion channels. Spinel LiMnO is considered a promising low-cost positive electrode material in the context of reducing scarce elements such as cobalt and nickel from advanced lithium-ion batteries. However, the rapid capacity degradation and inadequate rate capabilities induced by the Jahn-Teller distortion and the manganese dissolution have limited the large-scale adoption of spinel LiMnO for decades.

Food security is the foundation of national security, which is related to economic development and social stability. Shanxi Province, as China's grain production and marketing balance area, has rich agricultural resources and profound farming civilization, its food security situation is not only related to its own economic development, but also has a strategic position that can not be ignored in the national food security system. Based on the concept and goal of the development of food security in Shanxi Province, from the five aspects of quantity security, economic security, policy security, resource sustainability and ecological sustainability, this paper constructs the evaluation index system of food security in Shanxi Province, including the fluctuation rate of grain production and the sown area of grain, and establishes the entropy TOPSIS model to evaluate the development level of food security in Shanxi Province.

Purpose: To assess and compare the diagnostic efficiency of histogram analysis of monochromatic and iodine images derived from spectral CT in predicting Ki-67 expression in gastric gastrointestinal stromal tumors (gGIST).
Methods: Sixty-five patients with gGIST who underwent spectral CT were divided into a low-level Ki-67 expression group (LEG, Ki-67 < 10%, n = 33) and a high-level Ki-67 expression group (HEG, Ki-67 ≥ 10%, n = 32). Conventional CT features were extracted and compared.

Phase separation is essential for membrane function, and alterations in phase coexistence by membrane-interacting molecules, such as nicotine, can impair membrane stability. With the increasing use of e-cigarettes, concerns have arisen about the impact of nicotine on pulmonary surfactants. Here, we used differential scanning calorimetry (DSC), molecular dynamics (MD) simulations, and electron spin resonance (ESR) to examine nicotine's effect on the phase coexistence of two surfactant models: pure DPPC and a DPPC/POPC/POPG mixture.

Hybrid organic-inorganic perovskites (HOIP) have emerged in recent years as highly promising semiconducting materials for a wide range of optoelectronic and energy applications. Nevertheless, the rotational dynamics of the organic components and many-molecule interdependencies, which may strongly impact the functional properties of HOIP, are not yet fully understood. In this study, we quantitatively analyze the orientational disorder and molecular correlations in archetypal perovskite CHNHPbI (MAPI) by performing comprehensive molecular dynamics simulations and entropy calculations.
