Leptokurtic Portfolio Theory

open access: yes, 2005
The question of optimal portfolio is addressed. The conventional Markowitz portfolio optimisation is discussed and the shortcomings due to non-Gaussian security returns are outlined. A method is proposed to minimise the likelihood of extreme non-Gaussian

Developing evidence‐based, cost‐effective P4 cancer medicine for driving innovation in prevention, therapeutics, patient care and reducing healthcare inequalities

open access: yesMolecular Oncology, EarlyView.
The cancer problem is increasing globally with projections up to the year 2050 showing unfavourable outcomes in terms of incidence and cancer‐related deaths. The main challenges are prevention, improved therapeutics resulting in increased cure rates and enhanced health‐related quality of life.

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

Sebum Components Dampen the Efficacy of Skin Disinfectants against Cutibacterium acnes Biofilms

open access: yesMicroorganisms
At Canadian Blood Services, despite the use of 2% chlorhexidine and 70% isopropyl alcohol (standard disinfectant, SD) prior to venipuncture, Cutibacterium acnes evades eradication and is a major contaminant of platelet concentrates (PCs). Since C.

A Methodological Review of Piezoelectric Based Acoustic Wave Generation and Detection Techniques for Structural Health Monitoring

open access: yesInternational Journal of Aerospace Engineering, 2013
Piezoelectric transducers have a long history of applications in nondestructive evaluation of material and structure integrity owing to their ability of transforming mechanical energy to electrical energy and vice versa.

s‐Orbital Mediated Metavalent Bonding Enables State‐Of‐The‐Art n‐Type AgBiSe2 Thermoelectrics

open access: yesAdvanced Functional Materials, EarlyView.
Metavalent bonding (MVB) underpins the exceptional property portfolio of chalcogenides. Typical MVB solids are mainly found in p‐bonded systems. This work reveals that MVB can also be formed with s‐p orbital interactions upon forming a single‐electron σ‐bond, as exemplified in AgBiSe2.

The Impact of an Immersive Block Model on International Postgraduate Student Success and Satisfaction: An Australian Case Study

open access: yesEducation Sciences
International postgraduate students enrich higher education institutions and host societies, contributing economically, socially, and culturally. However, much less is known about how to improve their academic outcomes compared with their undergraduate ...

Exploration of portfolio characteristics for the recognition of prior learning : the identification, assessment and recognition of actual competencies of highly-skilled immigrants [PDF]

open access: yes, 2007
This research study explores the characteristics of the portfolio as an instrument for highly-skilled immigrants to facilitate the identification, assessment and recognition of their actual competencies in order to define guidelines for portfolio design ...

Stepwise On‐Surface Synthesis and Transformations of Two‐Dimensional Covalent Organic Frameworks by Controlled Thermal Stimuli

open access: yesAdvanced Materials, EarlyView.
The seminal transformation of a 2D‐COF (SURFCOF‐IMDEA1) into a 2D porous COF (SURFCOF‐IMDEA2) on Au(111) by a sequential C‐C coupling and ladderization triggered by thermal annealing steps at increasing temperatures is reported. Abstract The development of covalent organic frameworks (COFs) is currently a primary objective in materials science, taking ...

Backlogs are a dynamic system, not a warehousing problem

open access: yesForensic Science International: Synergy, 2020
Addressing casework backlogs would seem to represent “low hanging fruit” for increasing offender apprehension and improving justice. Yet, after years of grant funding for backlog reduction and capacity building, backlogged cases, especially DNA cases ...
