Experimental investigation of deformable additives as loss circulation control agent during drilling and well construction

open access: yesScientific Reports
Lost circulation is known as one of the most important challenges during drilling. In addition to high costs due to mud loss and nonproductive time, lost circulation may lead to several consequences, including stuck pipes, wellbore collapse, poor hole ...

Integration of circadian and hypoxia signaling via non‐canonical heterodimerization

open access: yesFEBS Letters, EarlyView.
CLOCK, BMAL1, and HIFs are basic helix‐loop‐helix and Per‐Arnt‐Sim domain (bHLH‐PAS) proteins, which function as transcription factors. bHLH‐PAS proteins are designated in two classes. Many class I proteins are regulated by environmental signals via their PAS domains, but such signals have not been identified for all.

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Ultrasound-assisted oxidative desulfurization of model fuel oil using HPW/Al2O3/PANI composite: experimental and kinetic modeling

open access: yesScientific Reports
In the present study, a novel composite catalyst HPW/Al2O3/PANI (γ-Al2O3, phosphotungstic acid (HPW), polyaniline (PANI)) was synthesized via the ultrasonic-assisted method.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Putting prototypes in place

open access: yesCognition, 2019
It has recently been proposed that natural concepts are those represented by the cells of an optimally partitioned similarity space. In this proposal, optimal partitioning has been defined in terms of rational design criteria, criteria that a good engineer would adopt if asked to develop a conceptual system.

Use of put options as insurance [PDF]

open access: yes
An important question in insurance is the amount of coverage to purchase. A standard microeconomic model for insurance shows that full insurance is optimal.

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...
