TL;DR: A high extracellular matrix remodeling favors tumor progression in hepatocellular carcinomas, and tumor recurrence was associated with 4.6‐ and 2.8‐fold (P < .05) higher collagen I and MMP2 mRNA levels, respectively, in cirrhotic livers.

TL;DR: The broad and expanding spectrum of these techniques in the ultrafast time domain is delivering new insight into the dynamics of molecular systems, of solutions, of solids, and of biosystems.
Abstract: We review the tremendous advances in ultrafast X-ray science, over the past 15 years, making the best use of new ultrashort X-ray sources including table-top or large-scale facilities. Different complementary X-ray-based techniques, including spectroscopy, scattering, and diffraction, are presented. The broad and expanding spectrum of these techniques in the ultrafast time domain is delivering new insight into the dynamics of molecular systems, of solutions, of solids, and of biosystems. Probing the time evolution of the electronic and structural degrees of freedom of these systems on the time scales of femtosecond to picoseconds delivers new insight into our understanding of dynamical matter.

TL;DR: It is argued that river systems have a fundamental need for appropriate amounts and timing of water to maintain their biophysical integrity and it is suggested that cost of long-term and long-distance cumulative impacts of hydrological changes should be evaluated against short-term economic benefits to determine the real environmental costs.
Abstract: Understanding the environmental consequences of changing water regimes is a daunting challenge for both resource managers and ecologists. Balancing human demands for fresh water with the needs of the environment for water in appropriate amounts and at the appropriate times are shaping the ways by which this natural resource will be used in the future. Based on past decisions that have rendered many freshwater resources unsuitable for use, we argue that river systems have a fundamental need for appropriate amounts and timing of water to maintain their biophysical integrity. Biophysical integrity is fundamental for the formulation of future sustainable management strategies. This article addresses three basic ecological principles driving the biogeochemical cycle of nitrogen in river systems. These are (1) how the mode of nitrogen delivery affects river ecosystem functioning, (2) how increasing contact between water and soil or sediment increases nitrogen retention and processing, and (3) the role of floods and droughts as important natural events that strongly influence pathways of nitrogen cycling in fluvial systems. New challenges related to the cumulative impact of water regime change, the scale of appraisal of these impacts, and the determination of the impacts due to natural and human changes are discussed. It is suggested that cost of long-term and long-distance cumulative impacts of hydrological changes should be evaluated against short-term economic benefits to determine the real environmental costs.

TL;DR: This model correctly captures the Lagrangian velocity correlation properties and is demonstrated to represent a forward model for predicting transport in highly heterogeneous porous media for different types of velocity organizations.
Abstract: We define an effective Lagrangian statistical model in phase space (x, t, v) for describing transport in highly heterogeneous velocity fields with complex spatial organizations. The spatial Markovian nature (and temporal non-Markovian nature) of Lagrangian velocities leads to an effective transport description that turns out to be a correlated continuous time random walk. This model correctly captures the Lagrangian velocity correlation properties and is demonstrated to represent a forward model for predicting transport in highly heterogeneous porous media for different types of velocity organizations.
