This occurs when a disproportionate number of records are assigned to a single user or a small group of users, resulting in a skewed distribution of data. The issue of Ownership Data Skew can arise for various reasons such as a lack of proper allocation of records, a high volume of records...
How to find the skewed table If the number of tables in the database is less than 10,000, use the PGXC_GET_TABLE_SKEWNESS view to query data skew of all tables in the database. 1 SELECT * FROM pgxc_get_table_skewness ORDER BY totalsize DESC; If the number of tables in the d...
In species where both parents have equal caring capabilities, the desertion of either parent is often influenced by the availability of potential mates22—parental care by the abundant sex is expected to be greater than that of the scarcer sex due to limited future reproductive potential23. Detail...
While the ASR is of central importance to population structure, it is but one of nine types of sex ratios measured across different ages/stages of development (e.g., fertilization, birth, and independence; Fig.1)18. The ASR includes all individuals that have reached sexual maturity, regardless...
Among tandem mutations that occur simultaneously at adjacent sites, we find an especially skewed distribution of ancestral and derived alleles, with GC → AA, GA → TT, and their reverse complements making up 27% of the total. These mutations have been previously shown to dominate the spectrum ...
Thus, it is possible that the latency of lymphoid tumorigenesis was skewed by modifier genes in the small TM cohort analyzed by Vanasse et al. Finally, Vanasse et al. did not document brain histopathology in their TM mice, so undetected CNS leukemia may have accounted for the unexplained ...
When we classified the events according to their amplitude, and we constructed frequency histograms, a typical distribution was evident, with an initial peak and then a skewed tail over larger amplitudes (Figure S4A), particularly for the GluK4over mice. To avoid the influence of the skewed ...
(95% CI) of 2.09 (0.826, 2.394) mg/kg in RM group (Fig.1A; Table1). The contents of PS fragments were significantly higher in RM vs. HC villous tissues. The distribution of PS fragments followed a skewed distribution in HC villous tissues(Fig.1B, C)and a normal distribution in RM...
In summary, our results suggest that the complete deletion of AUTS2 resulted in skewed cell composition with a decreased diversity of cells committed to neuronal lineage and an overamplification of ChP-like cells. AUTS2 regulates the transition of neural stem cells to progenitors To better ...
Compared with the overall distribution of clinical subtypes of pregnancy loss, pregnancy terminations and perinatal death11, this cohort is skewed towards terminated pregnancies of fetuses with congenital abnormalities, and the reported major organ systems (Fig. 2 and Extended Data Figs. 1 and 2) ...
