R&D-Productivity Dynamics: Causality, Lags, and "Dry Holes" [PDF]
We study four issues in R&D–productivity dynamics: does R&D Granger cause productivity, is there a lag between R&D and its productivity effects, does the potency of R&D vary in timing and magnitude, and what is the role of R&D spillovers and aggregate ...

대한영상의학회지, 2016 Purpose Parallel imaging mitigates susceptibility artifacts that can adversely affect diffusion tensor tractography (DTT) of the pons depending on the reduction (R) factor. We aimed to find the optimal R factor for DTT of the pons that would allow us to

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Factor-Augmenting Technical Change: an Empirical Assessment [PDF]
This paper estimates factor-specific technical change and input substitution using a structural approach. It improves upon the existing literature by introducing technology drivers for factor productivities and by assessing the impact of endogenous ...

Factor structure of the Life Orientation Test-Revised (LOT-R)
Acta Colombiana de Psicología, 2017 Optimism and pessimism are conceptualized as generalized expectations about events happening in people's lives, and are regarded as stable dispositions. The construct of optimism can be understood as being one-dimensional and bipolar, in other words, it ...

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
