Dynamics of Pyrene Excimer in a Cholesteryl-Based Supramolecular Host Matrix.

Aggregation-caused quenching (ACQ) reduces luminescence and compromises brightness in solid-state displays, necessitating strategies to mitigate its effects for enhanced performance. This study presents cost-effective method to mitigate ACQ of pyrene by co-assembling polycyclic aromatic hydrocarbons within low molecular weight gelator. Synthesized from readily available materials - cholesteryl chloroformate and pentaerythritol - in one-step reaction, gelator incorporates four cholesteryl units, reported to promote robust supramolecular gels in various solvents.

Complicated neurological pathways: tuberculoma with Guillain-Barre syndrome - an uncharted clinical odyssey.

Tuberculosis is a global disease and presents with an array of neurological manifestations. Presentation varies from meningitis, radiculo-myelitis, tuberculoma, brain abscess and other combinations. The association of Guillain-Barre' syndrome (GBS) with tuberculosis has been reported in a few reports.

Fractal dimension analysis of stock prices of selected resulting companies after mergers and acquisitions.

This study focuses on the short-run wealth of listed firms' shareholders. Currently, all of the resulting organizations offer competitive pricing tactics to create a superior environment for our ongoing establishment. Some time ago, it was noted that a merger occurred, although some functions and technology integration remained with the previous structure.

Analogue and structure based approaches for modelling HIV-1 integrase inhibitors.

A set of 220 inhibitors belonging to different structure classes and having HIV-1 integrase activity were collected along with their experimental pIC values. Geometries of all the inhibitors were fully optimized using B3LYP/6-31 + G(d) level of theory. These ligands were docked against 4 different HIV-1 integrase receptors (PDB IDs: 4LH5, 5KRS, 3ZSQ and 3ZSV).

A systematic survey of RUM process parameter optimization and their influence on part characteristics of nickel 718.

This research is focused on the drilling of Nickel based super alloy with diamond metal core drill and identified the significant parameters of rotary ultrasonic machining that optimise the machining rate (MR) and surface quality. Four general parameters: workpiece material, workpiece thickness, tool material, and tool size; and four RUM parameters: tool rotational, feed rate, ultrasonic power rating, and abrasive grit size of the tool were tested against and surface quality of the cut. The results indicated that the maximum value of MR of 0.

Performability evaluation, validation and optimization for the steam generation system of a coal-fired thermal power plant.

The present paper talks over performability evaluation for a steam generation system of a Coal Fired Thermal Power Plant (CFTPP) using the concept of the Markov method. A steam generation system provides a suitable amount of steam for the sound functioning of the plant. The system comprises five subsystems, i.

Mechanical conflict caused by a cell-wall-loosening enzyme activates de novo shoot regeneration.

Cellular heterogeneity is a hallmark of multicellular organisms. During shoot regeneration from undifferentiated callus, only a select few cells, called progenitors, develop into shoot. How these cells are selected and what governs their subsequent progression to a patterned organ system is unknown.

Genome Editing and Designer Crops for the Future.

Domestication spanning over thousands of years led to the evolution of crops that are being cultivated in recent times. Later, selective breeding methods were practiced by human to produce improved cultivars/germplasm. Classical breeding was further transformed into molecular- and genomics-assisted breeding strategies, however, these approaches are labor-intensive and time-consuming.

Hormonal crosstalk in regulating salinity stress tolerance in graminaceous crops.

Soil salinity is one of the major threats that pose challenges to global cereal productivity and food security. Cereals have evolved sophisticated mechanisms to circumvent stress at morpho-physiological, biochemical, and molecular levels. Salt stress cues are perceived by the roots, which trigger the underlying signaling pathways that involve phytohormones.

Performance evaluation of friction stir welding using machine learning approaches.

The aim of the present study is to evaluate the potential of sophisticated machine learning methodologies, i.e. Gaussian process (GPR) regression, support vector machining (SVM), and multi-linear regression (MLR) for ultimate tensile strength (UTS) of friction stir welded joint.

Oxidation of Cr(III) in tannery sludge to Cr(VI): field observations and theoretical assessment.

Sludge, soil and leachate samples collected from a chromium-contaminated tannery waste dumping site in Kanpur, India, were found to contain considerable amounts of Cr(VI), despite the fresh tannery sludge containing little or no Cr(VI). Literature reports suggested that dry Cr(III) precipitates could be converted to Cr(VI) when heated in the presence of oxygen. Also, Cr(III) in aqueous phase could be oxidized through interaction with manganese dioxide (MnO2) surface to Cr(VI).
