This page shows the detailed analysis of a specific feature in the Sparse Autoencoder (SAE). It includes the semantic interpretation generated by the LLM, the top activating documents that trigger this feature, and statistical metrics like density and activation distribution.

Semantic Interpretation
gemma3:12b #18

The positive examples consistently describe research focused on molecular and cellular biological processes, particularly within plants (Arabidopsis) and other organisms (rat, rabbit, Bacillus subtilis). Key features include: * **Gene Regulation:** Studies involving gene expression, promoters, and regulatory elements (e.g., PISTILLATA, LEAFY, UNUSUAL FLORAL ORGANS, NsrR, AlsR, Rex). * **Protein Modification & Function:** Analysis of protein modifications (S-nitrosylation), enzymatic activity (serine esterase, phospholipase A2), and protein synthesis. * **Cellular Processes:** Descriptions of cellular responses (hypersensitive response, mineralisation, anaerobic metabolism), signaling pathways (calcium influx, protein kinase C), and metabolic processes (arachidonic acid release, prostacyclin synthesis). * **Experimental Techniques:** Use of techniques like proteomic analysis, 2-DE, MS, gene fusion constructs (PI::GUS), and pharmacological inhibitors. The negative examples, conversely, deal with topics like mold detection, infections in the elderly, teat dip efficacy, and supermarket interventions – none of which share these molecular and cellular biological features. The neuron appears to be highly specific to research detailing molecular mechanisms and cellular processes.

STATISTICS & DISTRIBUTION
Statistics Explained

Density
Fraction of documents where this feature activates at least once.
Higher density = feature appears frequently across the dataset.

Peak Activation
Maximum activation value observed for this feature over all documents.

Activation Histogram
Distribution of all activation values for this feature. Each bar represents a bin (range) of values, and its height shows how many documents fall in that range.

DOC #428 ANALYZE
ACT: 3.6169
The Arabidopsis floral homeotic gene PISTILLATA is regulated by discrete cis-elements responsive to induction and maintenance signals. PISTILLATA is a B-class floral organ identity gene required for the normal development of petals and stamens in Arabidopsis. PISTILLATA expression is induced in the stage 3 flowers (early expression) and is maintai…

Proteomic analysis of S-nitrosylated proteins in Arabidopsis thaliana undergoing hypersensitive response. Nitric oxide (NO) has a fundamental role in the plant hypersensitive disease resistance response (HR), and S-nitrosylation is emerging as an important mechanism for the transduction of its bioactivity. A key step toward elucidating the mechani…

Prostacyclin synthesis elicited by endothelin-1 in rat aorta is mediated by an ETA receptor via influx of calcium and is independent of protein kinase C. The purpose of this study was to characterize the receptor(s) and second messenger systems involved in prostacyclin (prostaglandin [PG] I2) synthesis elicited by endothelin (ET)-1 in the rat aort…

Role of serine esterase in hydrogen peroxide-mediated activation of phospholipase A2 in rabbit pulmonary arterial smooth muscle cells. Exposure of rabbit pulmonary arterial smooth muscle cells to hydrogen peroxide cause dose-dependent stimulation of [14C] arachidonic acid (AA) release and enhancement of the cell membrane-associated phospholipase A…

Inhibition of osteoblast function in vitro by aminobisphosphonates. Bisphosphonates are analogues of pyrophosphate, a key physicochemical inhibitor of mineralisation. We examined the direct actions of bisphosphonates on the function of cultured osteoblasts derived from rat calvariae. Treatment with zoledronate, the most potent bisphosphonate studi…

Regulation of the anaerobic metabolism in Bacillus subtilis. The Gram-positive soil bacterium Bacillus subtilis encounters changing environmental conditions in its habitat. The access to oxygen determines the mode of energy generation. A complex regulatory network is employed to switch from oxygen respiration to nitrate respiration and various fer…
