Summary: This study investigates the strategic question of reallocating dock capacity in bike-sharing systems and develops mathematical models and algorithms to solve this problem. The findings suggest that using a polynomial-time allocation algorithm can effectively optimize dock allocation, improve service quality, and provide a metric to compare the impact of dock reallocation and daily bike rebalancing.

Summary: This paper quantifies the efficiency of resource allocation methods in flexgrid optical networks and proposes a metric-based evaluation approach. The paper introduces an integer linear programming formulation for the routing and spectrum assignment problem and suggests evaluating methods based on long-term performance and early congestion assessment. Additionally, a set of network remaining capacity metrics suited for assessing congestion levels is introduced.

Summary: The article presents research on obtaining a low-temperature calcination binder from dolomitic limestone with a MgO content of less than 20%. The materials were calcinated at temperatures ranging from 700 to 800 degrees Celsius and firing times of 25-45 minutes. The results indicate that semi-calcination product caustic dolomite with a minimum content of residual Mg(CO3)2 and free CaO was achieved, with a bending strength of 10-11 MPa. The article also discusses the physical-mechanical characteristics and mineral composition of the samples, as well as the development of a three-dimensional model for the production of glass dolomite slabs.

Summary: The study found that diffusion measures from seven white matter tracts can predict the conversion to Alzheimer's Disease (AD), with axial diffusivity being the most predictive measure. Additional analyses revealed that specific white matter changes in certain brain regions are the best predictors of conversion from MCI to AD.

Summary: China's rare earth exports have significant environmental costs, with foreign consumers responsible for over half of these costs. East Asian countries, particularly Japan and South Korea, make the largest contribution to these costs. The environmental impact is mainly caused by rare earth raw materials and high value-added products. Recommendations include rational pricing and production-and consumption-based measures to mitigate environmental impacts.

Summary: This study evaluates the feasibility of incorporating fibrillated polypropylene fibers (FPFs) into adobe mixtures (AMs) and investigates the effects of different dosages of FPFs on the performance of AMs. The results show that the incorporation of FPFs can improve the water erosion resistance and flexural toughness of AMs, but it decreases the bulk density, compressive strength, and flexural strength. Additionally, fiber clustering is a significant limitation when using FPFs in AMs.

Summary: This article introduces the concept of themes as an investment dimension and proposes a framework for allocating to thematic investments at a strategic asset allocation level. The approach takes into account the expected excess return from exposure to the theme and traditional risk factors through robust portfolio optimization. An example is provided to illustrate the integration of thematic investments in traditional multi-asset portfolios.

Summary: A Bragg grating is successfully formed in a strongly coupled seven-core fiber. Two separate Bragg resonance notches are observed in the transmission spectrum, corresponding to backward coupling of two supermodes of the fiber. The mode coupling mechanism is investigated both theoretically and experimentally, and the results agree well. The device shows potential for simultaneous measurement of temperature and curvature.

Summary: This paper discusses a resource allocation problem in a public service system with multiple service providers and patients, and establishes a queueing-game-theoretical model to capture the interactions between the providers. The socially optimal reimbursement policy is found to be non-monotone in both the effectiveness parameter and the joining probability of patients. Individual behavior of patients does not necessarily lead to systems more congested than what is socially desirable.

Summary: A new method has been proposed to achieve phase-only sampled multichannel helical long-period fiber grating by superposing sampling HLPGs with seed HLPG in the same region. This approach greatly simplifies the fabrication process and provides more design and fabrication flexibilities, as demonstrated with successful 3-channel and 5-channel HLPG. The fabricated HLPGs exhibit orbital angular momentum (OAM) modes at all channels, indicating potential applications in multi-wavelength OAM mode conversion.
