Logging-based assessment of low-resistivity oil zones: A case study from Sudan

Energy Geoscience, 2023
The reservoirs in the N oilfield in Sudan feature a complex sedimentary environment, which has led to a widespread development of low-resistivity oil zones, accounting for as high as 37% of the total oil zones.

Expected convergence properties of BGP [PDF]

Computer Networks, 2005
Border gateway protocol (BGP), the de facto standard used for interdomain routing, is a key enabler for interconnecting largely autonomous IP-subnetwork domains into large IP-networks. Since data transfer may not be possible until stable routes are learned, it is not only critical for BGP to converge after any policy or topology changes, but it is ...

Q estimation of seismic reflection data and its application in oil and gas exploration

Dizhi lixue xuebao, 2022
In oil and gas seismic exploration, when the seismic wave propagates in the earth medium, it will encounter obvious absorption and attenuation, resulting in the main frequency of the seismic signal shifting to the low-frequency end.

Experimental Study and Theoretical Interpretation of Partial Saturation Effects on P- and S-Wave Velocities and Anisotropy in Artificial Tight Sandstones with Controlled Aligned Fractures

Applied Sciences
This study investigates the combined effects of partial saturation and aligned fractures on P- and S-wave velocities and anisotropy in tight sandstones. Ultrasonic measurements (0.5 MHz) were conducted on three synthetic samples with a matrix porosity of

Intestinal ultrasound versus magnetic resonance enterography for detecting small bowel Crohn's disease in children

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives In Crohn's disease (CD), magnetic resonance enterography (MRE) is used to assess small bowel disease activity. Intestinal ultrasound (IUS) is a less invasive, cheaper and more easily accessible imaging modality in CD. This study assesses the diagnostic accuracy of IUS versus MRE and defines an optimal bowel wall thickness (BWT) cut ...

Chemoenzymatic Synthesis of Well‐Defined α(2,8)‐ and α(2,9)‐Linked Oligosialosides

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Well‐defined α(2,8)‐ and α(2,9)‐linked oligosialic acids of different lengths can be prepared by employing recombinant bacterial polysialyltransferases in combination with chemically modified CMP‐Neu5Ac derivatives. After transfer, a sialoside is formed bearing an artificial entity, which blocks further glycosylation.

Children's and caregivers' experiences, information needs, and willingness to change lifestyle in metabolic dysfunction‐associated steatotic liver disease care: A multicenter study across Europe

Journal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objective Little is known about children's and caregivers' experiences, information needs, and willingness to change lifestyle following evaluation for metabolic dysfunction‐associated steatotic liver disease (MASLD). This study assessed these aspects across European hepatology clinics.
