Is there a “case for property” all the time? [PDF]

, 2002
The “case for property” in the mixed-asset portfolio is a topic of continuing interest to practitioners and academics. Such an analysis typically is performed over a fixed period of time and the optimum allocation to property inferred from the weight ...

Regularizing Portfolio Optimization [PDF]

, 2009
The optimization of large portfolios displays an inherent instability to estimation error. This poses a fundamental problem, because solutions that are not stable under sample fluctuations may look optimal for a given sample, but are, in effect, very far

A New Method for Evaluating and Selecting Portfolio of New Product Development Projects . [PDF]

Muṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2017
Differentiation through NPD is one of the most effective ways to achieve success. However, because of the failure rate of these projects, it could not be expected firm’ success due to only one new product development project.

The Core–Shell Conformational Space of Compartmentalized Single‐Chain Nanoparticles by Paramagnetic and Hyperpolarized NMR Spectroscopy

Advanced Science, EarlyView.
Combinations of integrative NMR spectroscopy and molecular dynamics simulations reveal the internal structural dynamics of single‐chain nanoparticles. Abstract Single‐chain nanoparticles (SCNPs) are formed by the collapse of individual polymer chains, generating entities comparable to proteins in size, internal structure, and function.

Genetically‐Programmed Hypervesiculation of Lactiplantibacillus Plantarum Increases Production of Bacterial Extracellular Vesicles with Therapeutic Efficacy in a Preclinical Inflammatory Bowel Disease Model

Advanced Science, EarlyView.
The development of a novel engineered strain of Lactiplantibacillus plantarum (Lp) is reported that can produce bacterial extracellular vesicles (BEVs) at >60‐fold higher yields than the unmodified parental strain. These Lp BEVs retain therapeutic bioactivity as validated in a mouse model of dextran sodium sulfate‐induced colitis.

Donor age contributes more to the rheological properties of stored red blood cells than donor sex and biological age distribution

Blood Advances
: The quality of stored red cell concentrates (RCCs) has been linked to the biological age distribution of red blood cell (RBC) subpopulations. Teenage male RCCs contain higher proportions of biologically old RBCs, with poorer quality.
