Dynamic Space Efficient Hashing

, 2017
We consider space efficient hash tables that can grow and shrink dynamically and are always highly space efficient, i.e., their space consumption is always close to the lower bound even while growing and when taking into account storage that is only needed temporarily. None of the traditionally used hash tables have this property.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

FEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Beyond the reporting of disturbed areas: the use of Deter to analyze the spatiotemporal patterns of forest degradation in the Amazon

Geoscience Letters
The Brazilian Amazon, a critical component of Earth’s climate regulation and biodiversity, has been increasingly affected by forest degradation, a process less monitored than deforestation.

Analytical solutions for performance of existing shield tunnel subjected to overlying excavation under anti-uplift portal frame

Yantu gongcheng xuebao
The heave of the existing shield tunnels will be induced due to the above excavation, and then structural damages, including leakage and cracking, easily happen.

Efficient Conditional Tracepoints in Kernel Space [PDF]

The Open Cybernetics & Systemics Journal, 2012
With kernel static tracepoints, it is now possible to add instrumentation to the Linux kernel and obtain a low overhead trace of the whole system. However, these static tracepoints may be insufficient to diagnose the source of a functional or performance problem.

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

FEBS Open Bio, EarlyView.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

Deep learning-based prediction method for chamber pressure field in shield machines

Yantu gongcheng xuebao
The chamber pressure is a key factor in the core issues of the stress state of equipment and the stability of tunnel face during shield tunneling. It exhibits significant spatial variability, and its formation and evolution originate from the complex ...
