Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Performance Evaluation with Stochastic Discount Factors [PDF]
We study the use of stochastic discount factor (SDF) models in evaluating the investment performance of portfolio managers. By constructing artificial mutual funds with known levels of investment ability, we evaluate a large set of SDF models.

Color Center Formation in Silicon‐On‐Insulator for On‐Chip Photonic Integration
Advanced Optical Materials, EarlyView.ABSTRACT Color centers in silicon have great potential as single photon sources for quantum technologies. Some of them – like the T center – also possess optically‐active spins that enable spin‐photon interfaces for generating entangled photons and multi‐spin registers. This paper explores the generation of several types of color centers in silicon for

A Proposal for a New Prescriptive Discounting Scheme: The Intergenerational Discount Rate [PDF]
Cost-benefit analyses require comparing costs and benefits that occur at different points in time. Doing so, however, creates conflicts between short-term considerations — a discounting scheme has to be consistent with observed behaviours — and long-term

Red Fluorescent Protein‐Metal Organic Framework Hybrids for Lighting Applications
Advanced Optical Materials, EarlyView.We demonstrate the encapsulation in a metal‐organic framework (MOF) of two red fluorescent proteins, DsRed and mCherry. The materials conserve all spectroscopical and structural properties of the underlying components, which allows for their implementation as color down‐converting materials in bio‐hybrid light‐emitting diodes, which exhibit average 3 ...

Smoking, discount rates, and returns to education [PDF]
Individual time preference determines schooling enrolment. Moreover, smoking behavior in early ages has been shown to be highly related to time preference rates.

Advanced Optical Materials, EarlyView.A Bayesian optimization framework identifies the ideal composition for Lu2(MoO4)3:Yb–Er–Tm phosphors with minimal experimental trials. By leveraging the host's negative thermal expansion, the material achieves remarkable thermal quenching compensation.

The Diversification Discount: Cash Flows vs. Returns [PDF]
Diversified firms have different values than comparable portfolios of single-segment firms. These value differences must be due to differences in either future cash flows or future returns.

Scalable Task Planning via Large Language Models and Structured World Representations
Advanced Robotics Research, EarlyView.This work efficiently combines graph‐based world representations with the commonsense knowledge in Large Language Models to enhance planning techniques for the large‐scale environments that modern robots will need to face. Planning methods often struggle with computational intractability when solving task‐level problems in large‐scale environments ...

The Impact of Education on the Subjective Discount Rate in Ugandan Villages [PDF]
Heterogeneity in time discounting may reinforce the existing barriers to save and invest faced by rural populations in developing countries. We elicit a subjective discount rate for a varied sample of Ugandan villagers.
