Investigation of the pBR322 Exclusion Effect using Putative Rop Mutant pBR322 Plasmid pCAWK

Rop, repressor of primer, protein has been implicated in causing or contributing to plasmid pBR322 exclusion from Escherichia coli host cells. A recent study successfully created pCAWK, a putative mutated pBR322 plasmid with a non-functioning Rop protein. Whole cell PCR was perfo...

LAB #4159 PROMISING: LEDGER BENCH: Apply filter: Min confirmations >= 6 — improves win rate from 32.6% to 38.4% (+5.8pp, — E8 Intelligence Research

IDEA: Adjustment made to the live model — verify against the backtests: Apply filter: Min confirmations >= 6 — improves win rate from 32.6% to 38.4% (+5.8pp, n=831) SAME-WINDOW EFFECT: Applying a minimum 6-confirmation filter would have suppressed the two most recent rizzy5m entr...

Environmental quality and household energy vulnerability during global energy-sector disruptions: an adaptive indicator-based framework with evidence from Lithuania

Purpose Global crises and disruptions increasingly affect energy systems in ways that extend beyond market outcomes to environmental quality pressures and household vulnerability. However, crisis-impact evidence remains fragmented, limiting its usability for integrated monitoring...

MERLIN SCIENCE — Ancient Math's Core: Sexagesimal System and Euclid's Axiomatic Geometr — E8 Intelligence Research

Here's the narration for the MERLIN SCIENCE video: --- Today's breakthrough is a negative result, and that is precisely why it matters. After scanning a documentary corpus on ancient mathematics, the only mathematically substantive content is the Babylonian base-60 positional sys...

Formalized threshold reversible hiding in encrypted images in Post-Quantum settings

Abstract As advancements in computer vision emerge, the necessity for securing image processing techniques also arises. For this purpose, one of the promising methods is Reversible Data Hiding in Encrypted Images (RDHEI), which directly secures visual data while providing the opt...

Phi-Resonant E8 Continuum — E8 Intelligence Research

By aligning the 240 E8 root vectors with the discrete steps of the ancient sexagesimal proportion system, each phi‑coupled harmonic mode becomes a bridge between rational ratios and irrational continuity, preserving C‑infinity smoothness across all geometric constructions. This e...

Collatz Conjecture: Expository Sources Confirm No New Proof, Only Tao's 2019 Result — E8 Intelligence Research

FINDING: No new mathematical proof or partial result is presented in these sources — they are expository videos and a Wikipedia overview. The only substantive mathematical content is the standard Collatz map definition and Tao's known 2019 logarithmic-density result (not detailed...

Vegetation-Associated Mercury Patterns and Biogeochemical Signals in a Tropical Urban Mining Region

Abstract To evaluate vegetation-associated mercury (Hg) loading in tropical regions affected by artisanal and small-scale gold mining (ASGM), we quantified total mercury (HgT) in canopy leaves and leaf litter of Licania tomentosa across an ASGM-impacted urban center, Peixoto de A...

Genotyping Escherichia coli Isolates from Duck, Goose, and Gull Fecal Samples with Phylogenetic Markers using Multiplex Polymerase Chain Reaction for Application in Microbial Source Tracking

Multiplex polymerase chain reaction with phylogenetic markers, chuA, yjaA, and TspE4.C2 along with virulence gene, eae, was performed for determination of genotypic differences in Escherichia coli isolated from gull, goose, and duck. Results showed that isolates from goose freque...

Familiar Style and Calibrated Correction in Repeated AI Use. A framework for style recognition discrimination and substantive correction

Repeated users of an artificial-intelligence agent may learn both its competence and how it sounds. This paper proposes that acquired style congruence can change acceptance independently of evidential quality, while any benefit to error management may arise through more than one...

Factors associated with death before EMS arrival among emergency medical services-attended self-directed violence cases in southern Iran: a cross-sectional study

Abstract Background Self-directed violence (SDV) is an important public health concern, but evidence on factors associated with death before EMS arrival remains limited, particularly in low- and middle-income countries. This study examined factors associated with death before EMS...

Physics-guided learning framework based on a fractional single-particle model for battery state-of-health prediction

Accurate prediction of lithium-ion battery capacity degradation is crucial for ensuring safe and reliable energy storage systems. Traditional data-driven methods often lack physical interpretability, while existing physics-informed approaches typically rely on simplified integer-...

The Effect of Promoting High Expectations on Teachers’ Feedback to Students

Experimental studies show that teachers’ feedback expressing high expectations benefits students, but it is unclear whether instructing teachers to emphasize high standards alters their feedback content. We randomly assigned 963 teachers to provide feedback either “as you normall...

Voltage regulation methodology for low-voltage distribution networks with photovoltaic distributed generation

This paper proposes a methodology for voltage regulation at the Point of Common Coupling (PCC) of a secondary distribution network following the integration of photovoltaic distributed generation. Simulations were performed using data from a real distribution network in the state...

Local Learning Rules Under Honest Measurement: A Reproducibility-First Benchmark of e-prop, Hebbian, and R-STDP on Consumer Hardware

What changed in v1.1. Same benchmark, same numbers: this version corrects the references and the title page. Four citations now point at their published versions instead of the preprints — Korcsák-Gorzo et al., Neuromorphic Computing and Engineering 6(3):034024, 2026; Lin et al.,...

Integrated microbiomic and metabolomic analysis of irritable bowel syndrome comorbid with psychiatric symptoms

Irritable bowel syndrome (IBS), a chronic functional gastrointestinal disorder, exhibits high comorbidity with psychiatric symptoms. However, a comprehensive evaluation of psychiatric symptoms in IBS and their interactions with the gut microbiota and metabolic disorders is lackin...

An Integrated Fuzzy Min-Max Goal Programming Approach to Risk-Aware Portfolio Optimization

Background Stock market investment is sometimes perceived as being dependent on luck, particularly when investors are unfamiliar with systematic investment strategies. However, mathematical models can provide a structured approach to stock selection and portfolio optimization. In...

ENDOSCOPIC EVALUATION OF THE ANTIREFLUX VALVE AFTER FUNDOPLICATION: SYNTHESIS OF THE EVIDENCE AND PROPOSAL OF A FUNCTIONAL ENDOSCOPIC SCORE

Background. Antireflux fundoplication failure — recurrent reflux, dysphagia, gas-bloat syndrome, secondary to a herniated, slipped, too-tight, disrupted, or twisted valve — remains common, and its endoscopic diagnosis lacks a common, standardized reporting language. Aim. To narra...

Triple network effective connectivity imbalance across the Alzheimer’s disease spectrum and its modulation by intermittent theta burst stimulation

Alzheimer’s disease (AD) is characterized by progressive cognitive decline, yet the directed network mechanisms underlying this process and their responsiveness to neuromodulation remain incompletely understood. Guided by the triple network model, we investigated effective connec...

Permeability heterogeneity controls fluid migration and microseismicity evolution in The Geysers geothermal field, California

Fracture networks directly govern the efficiency of geothermal energy extraction and play a critical role in fluid migration and microearthquake generation. Using deep learning and Markov clustering, we build a high-resolution microseismic catalog covering the past decade for The...
