One-Pot Tandem Annulation of N -(2-Alkynylaryl)- N -sulfonylcyanamides with Water for the Synthesis of 2-Amino-3-carbonylindoles

Abstract A metal-free, one-pot tandem annulation of N-(2-alkynylaryl)-N-sulfonylcyanamides with water has been developed for synthesizing 2-amino-3-carbonylindoles. The reaction proceeds via isolable N,O-BF2-chelated intermediates, which undergo Et3N-mediated ring opening. Water...

Validation of HemoCue method and development of a revised hemoglobin cut-off to detect anemia in children aged 6–24-months

Background Accurate hemoglobin (Hb) measurement is essential for determining anemia prevalence at the population level. The HemoCue method, commonly used in resource poor settings, has been shown to overestimate Hb levels compared to the direct cyanmethemoglobin (DCM) method, lea...

Integrated energy management for embedded behavior prototyping in modular electric traction systems

This paper presents a compact and modular experimental platform for early-phase testing and validation of energy-aware behavior in electric autonomous and traction-based mobility systems under varying load conditions. Implemented on a 1:10-scale model, the platform integrates cam...

Same basis, not a lower bar: design of SameBasis, a teacher-controlled AI decision-support prototype for reasonable adjustments in Australian schools

In 2025, 27.0% of Australian school students received an educational adjustment due to disability. Under the Disability Standards for Education 2005, each adjustment must let the student take part on the same basis as their peers, yet the 2020 Review of the Standards found that m...

Comparative study of sound transmission loss enhancement in double-leaf walls using inertial amplifier and resonator

This paper investigates the sound transmission loss (STL) characteristics of double-leaf walls incorporating different mechanical impedance elements within the cavity, including a spring, a spring–mass–spring (SMS) resonator, and an inertial amplifier (IA). This study presents a...

Hourly PM2.5 Forecasting for Sustainable Urban Air Quality Management Through Multiresolution Learning and Environmental Context

Reliable hourly forecasts of fine particulate matter (PM2.5) can help cities anticipate deteriorating air quality and prepare measures to limit exposure. A central modeling challenge is to combine rapid pollution fluctuations with meteorological and ecological observations that a...

Promoting C–S Coupling for Hydroxymethanesulfonate Electrosynthesis over Cu-Mn Phthalocyanine Metal–Organic Frameworks

Abstract Electrocatalytic C–S coupling to synthesize high-value organosulfur chemicals represents a sustainable paradigm shift from traditional thermochemical processes, yet the electrocatalytic performance remains far from satisfactory. Herein, we develop Cu-Mn bimetallic phthal...

A projective-line quotient of the Rogalski–Sierra algebra

For the exact six-relation presentation R(alpha,beta) printed in the 2010 Oberwolfach report and 2012 Rogalski–Sierra article, the linear ideal I=(x3-x1,x4-x2) is nonzero, homogeneous and completely prime, strictly below the augmentation ideal. The exact quotient is the projectiv...

Babylonian Roots to Weyl Reflections: A Unified Symmetry — E8 Intelligence Research

FINDING: Babylonian sexagesimal quadratic methods prefigure Vieta jumping's root-pair symmetry, which itself mirrors Weyl group reflections in root systems. | MATH: Babylonian normal form \(x^2 - bx + c = 0\) with base-60 arithmetic; solution via \(x = \frac{b}{2} \pm \sqrt{(\fra...

Intraoperative detection of a false-negative facial motor evoked potential by direct facial nerve stimulation during vestibular schwannoma surgery: A case report

Background: False-negative transcranial facial motor evoked potential (FMEP) findings have previously been recognized retrospectively through discrepancies between preserved intraoperative FMEPs and postoperative facial palsy. To the best of our knowledge, no previous report has...

TSO: The Emergent Euclidean Metric at a Black-Hole Horizon: A Time–Space Oscillatory Representation

TSO: The Emergent Euclidean Metric at a Black-Hole Horizon: A Time–Space Oscillatory Representation What happens to geometry when the geometry itself breaks down? The event horizon of a black hole raises a fundamental question in theoretical physics: what happens to the Schwarzsc...

Technological Assessment of Unconventional Oil-Bearing Materials for Screw Pressing: Oil Recovery, Quality, Clarification, and Press Cake Characteristics

The technological suitability of unconventional oil-bearing materials for screw pressing depends on both raw-material characteristics and their behavior during processing and subsequent oil clarification. This study comparatively evaluated black sesame seeds (BSSs), white sesame...

ZIP-Code-Level Forecasting of Heating and Cooling Degree-Days for Urban Building Energy Planning in the United States

Heating and cooling degree-days (HDDs and CDDs) link outdoor temperature to building heating and cooling demand and serve as inputs for building energy and emissions models. Existing data-driven forecasts cover a few stations or provinces within single countries; none exists at n...
