Serial Correlation of Asset Returns and Optimal Portfolios for the Long and Short Term [PDF]
Optimal portfolios differ according to the length of time they are held without being rebalanced. For the case in which asset returns are identically and independently distributed, it has been shown that optimal portfolios become less diversified as the ...

Portfolios and Performance Assessment: Tools for Changing Pedagogy with Pre-Service Mathematics Teachers [PDF]
, 2000 Portfolios serve many roles in the development of prospective teachers. Faculty at Brooklyn College found that portfolios can play two other important roles — as tools in faculty development and as a conduit in the development and description of college ...

Twist Engineering of Hybrid 2D van der Waals‐Transition Metal Oxide Membranes
Advanced Physics Research, EarlyView.The integration of transition metal oxide membranes with 2D van der Waals materials offers exciting opportunities to study new interfacial phenomena. These interactions can create complex moiré patterns that change the materials' properties. Understanding these interactions, influenced by symmetry and distortion, poses significant challenges and ...

CAPM tests and alternative factor portfolio composition: getting the alphas right. [PDF]
We show that the results of a CAPM test are quite sensitive to the details of the test design. Especially crucial are the aspects related to the weight one gives to small, low-reputation stocks when constructing both the factor portfolios and the test or

Portfolios and the market geometry [PDF]
, 2011 A geometric analysis of the time series of returns has been performed in the past and it implied that the most of the systematic information of the market is contained in a space of small dimension.

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency
Advanced Physics Research, EarlyView.Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Anatomical Sciences Education, EarlyView.Abstract Educating clients and teaching and mentoring colleagues are crucial yet underappreciated elements of a veterinarian's professional duties. Unfortunately, veterinary curricula rarely explicitly aim to encourage students to develop effective teaching practices.

Anatomical Sciences Education, EarlyView.Abstract Anatomy and physiology are foundational to health science education, yet student engagement in these modules often declines during later years of study. This discursive article aims to describe a teaching intervention which increased student engagement and provide educator reflection of implementation and improvement over time.

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...
