Application of Multi-Scale Borehole Acoustics Imaging Technology to Fracturing Effects Evaluation

Cejing jishu
Multiple types of waves co-existing in borehole acoustic logging, can provide various insights about the formation, because of their complementary investigation depth and perspectives. Focusing on ever-increasing needs in post-fracturing evaluation, this

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Classification Evaluation Method for Complex Reservoirsin Xinglong Structural Belt

Cejing jishu
The reservoir of Linhe formation in the Xinglong tectonic belt of the Hetao basin is controlled by low geothermal temperature and late deep burial, with obvious weak diagenetic characteristics, strong heterogeneity of the reservoir, and complex pore ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

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 ...

Two-dimensional NMR characterization of gas–water distribution in tight sandstone reservoirs: a case study from the Ordos Basin, China

Frontiers in Earth Science
Tight sandstone reservoirs exhibit low porosity, low permeability, significant heterogeneity, and complex gas-water distribution patterns, posing significant challenges for conventional logging methods in accurate gas reservoir identification. Incomplete

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Differential expression of cancer‐related genes supports prediction of poor response to first‐line treatments in T‐ALL pediatric patients with high minimal residual disease

Molecular Oncology, EarlyView.
In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...

The Influencing Factors and Calculation Methods of Rock Electrical Parameters of Carbonate Reservoirs

Cejing jishu
The pore structure of carbonate reservoir is much more complex than that of clastic reservoir, and its rock electrical parameters m and n vary widely, which is difficult to obtain accurately, and the fixed rock electrical parameters are used to calculate

The matrix equation \(\log (XY)=\log (X)+\log (Y)\)

Linear Algebra and its Applications, 2010
Let \(X,Y\) be \(n\times n\) complex matrices such that \(X,Y,XY\) have no eigenvalues on \(\mathbb R^-\) and \(\log (XY)=\log (X)+\log (Y)\). The authors prove that if \(n=2\), or if \(n\geqslant 3\) and \(X,Y\) are simultaneously triangularizable, then \(X,Y\) commute. In both cases the problem is reduced to a result in complex analysis.
