05 Sep 2005TL;DR: This article describes what it believes to be some of the most important research challenges in software evolution.
Abstract: Today's information technology society increasingly relies on software at all levels. Nevertheless, software quality generally continues to fall short of expectations, and software systems continue to suffer from symptoms of aging as they are adapted to changing requirements and environments. The only way to overcome or avoid the negative effects of software aging is by placing change and evolution in the center of the software development process. In this article we describe what we believe to be some of the most important research challenges in software evolution. The goal of this document is to provide novel research directions in the software evolution domain.

TL;DR: In this paper, a critical separation distance of six perovskite oxides was found, corresponding to approximately 23 A˚, below which a decrease of the interface conductivity and carrier density occurs.
Abstract: Perovskite oxides exhibit a plethora of exceptional
properties, providing the basis for novel concepts of
oxide-electronic devices. The interest in these materials
is even extended by the remarkable characteristics of
their interfaces. Studies on single epitaxial connections
between the wide-bandgap insulators LaAlO3 and SrTiO3
have revealed them to be either high-mobility electron
conductors or insulating, depending on the atomic
stacking sequences. For device applications, as well as
for a basic understanding of the interface conduction
mechanism, it is important to investigate the electronic
coupling of closely spaced complementary interfaces.
Here we report the successful realization of such coupled
interfaces in SrTiO3–LaAlO3 thin-film multilayer structures.
We found a critical separation distance of six perovskite
unit cell layers, corresponding to approximately 23 A˚ ,
below which a decrease of the interface conductivity
and carrier density occurs. Interestingly, the high
carrier mobilities characterizing the separate conducting
interfaces are found to bemaintained in coupled structures
down to subnanometre interface spacing.

TL;DR: In tropical forests in particular, Topteco is close to growing-season air temperature and is projected to fall below it under all scenarios of future climate, suggesting a limited safe operating space for these ecosystems under future warming.
Abstract: The global distribution of the optimum air temperature for ecosystem-level gross primary productivity ([Formula: see text]) is poorly understood, despite its importance for ecosystem carbon uptake under future warming. We provide empirical evidence for the existence of such an optimum, using measurements of in situ eddy covariance and satellite-derived proxies, and report its global distribution. [Formula: see text] is consistently lower than the physiological optimum temperature of leaf-level photosynthetic capacity, which typically exceeds 30 °C. The global average [Formula: see text] is estimated to be 23 ± 6 °C, with warmer regions having higher [Formula: see text] values than colder regions. In tropical forests in particular, [Formula: see text] is close to growing-season air temperature and is projected to fall below it under all scenarios of future climate, suggesting a limited safe operating space for these ecosystems under future warming.

TL;DR: Recent advances in understanding of the calcification paradox are reviewed, including protein expression patterns governing both normal and ectopic mineralization, the conversion of vascular smooth muscle cells to bone-like cells, and the regulatory pathways involved in both bone and vessel mineralization.
