Tetrodotoxin: Chemistry, Toxicity, Source, Distribution and Detection

Tetrodotoxin (TTX) is a naturally occurring toxin that has been responsible for human intoxications and fatalities. Its usual route of toxicity is via the ingestion of contaminated puffer fish which are a culinary delicacy, especially in Ja...

Expectations and the Emergence of Nanotechnology

Although nanotechnology is often defined as operations on the 10 -9 meters, the lack of charisma in the scale-bound definitions has been fortified by remarkable dreams and alluring promises that spark excitement for nanotechnology. The stor...

Archaeologies of Complexity

An up-to-date and critical analysis of how archaeologists study past societies, Archaeologies of Complexity addresses the nature of contemporary archaeology and the study of social change, and debates the transition from perceived simple, e...

A Multi-Technique Study of 49 Gold <i>Solidi</i> from the Late Antique Period (Late 4th–Mid 6th Century AD)

This study investigates 49 gold solidi issued between the 4th and 5th century AD to determine their chemical composition. The coins were first catalogued by recording mass, diameter, and thickness. All specimens underwent non-destructive µ-...

Los nevados del Aconquija como sitio de frontera y espacio de observación lunar, Tucumán, noroeste de Argentina

Se presentan los aspectos sociales vinculados al concepto de frontera, el ushnu y la observación lunar en el sitio inca de La Ciudacita, provincia de Tucumán, noroeste de Argentina. El análisis se centra en la posibilidad de observar el lun...

Uncovering the Past: DNA Analysis of Skeletal Remains from the Medieval Bosnian City of Bobovac

Numerous archaeological sites in Bosnia and Herzegovina represent a historical heritage and testify to the rich cultural, social, and political life of medieval Bosnia. Bobovac, the capital of the Bosnian Kingdom after King Tvrtko I's coron...

Rings of Power or in Search of Early Elites

The article discusses the problem of identification of prehistoric elites on the example of the Usatovo culture. Archaeological evidence allows us to discern in the culture three separate strata or classes which are conditionally designated...

The Archaeology of Inequality.

The archaeology of inequality - material culture, domination and resistance, Rober T.Paynter and Randall H.McGuire struggling with pots in South Carolina, Leland Ferguson the continued pattern of dominance - landlord and tenant on the postb...

A History of Archaeological Thought

In its original edition, Bruce Trigger's book was the first ever to examine the history of archaeological thought from medieval times to the present in world-wide perspective. Now, in this new edition, he both updates the original work and ...

Archaeology of Knowledge

In France, a country that awards its intellectuals the status other countries give their rock stars, Michel Foucault was part of a glittering generation of thinkers, one which also included Sartre, de Beauvoir and Deleuze. One of the great ...

Core Scouring Dynamics and Gravitational Wave Consequences: Constraints on Supermassive Black Hole Binary Hardening

We present a multimessenger investigation of supermassive black hole binary (SBHB) hardening by jointly comparing models to the observed stellar mass deficits of nearby core galaxies and to nanohertz gravitational-wave background measuremen...

Testing the Physical Parameter Constraining Power of HCN and HNC with Neural Networks

We quantify the utility of HCN and HNC to characterize gas conditions in the nearby starburst galaxy NGC 253. We use measurements from the Atacama Large Millimeter/Submillimeter Array (ALMA) Large Program ALCHEMI: the ALMA Comprehensive Hig...

Ruling Out Compact Jets as the Dominant Source of Radio Emission in Radio-quiet, High-Eddington-ratio Active Galactic Nuclei

The origin of core radio emission in radio-quiet active galactic nuclei (AGNs) is still actively debated. General-relativistic magnetohydrodynamics simulations often predict the launching of moderately large-scale jets from super-Eddington ...

A Nonparametric Model for Multi-Manifold Clustering with Mixture of Gaussians and Graph Consistency

Multi-manifold clustering is among the most fundamental tasks in signal processing and machine learning. Although the existing multi-manifold clustering methods are quite powerful, learning the cluster number automatically from data is stil...

Correct Criterion of Crustal Failure Driven by Intense Magnetic Stress in Neutron Stars

Magnetar outbursts are powered by an intense magnetic field. The phenomenon has recently drawn significant attention because of a connection to some fast radio bursts that has been reported. Understanding magnetar outbursts may provide the ...

Power Load Probabilistic Prediction Based on Multi-Value Quantile Regression and Timing Fusion Ensemble Learning Model

The core component to ensure the refined and safe operation of distribution network scheduling is 10 kV bus load probabilistic prediction. However, existing probabilistic prediction methods suffer from insufficient dynamic feature extractio...

Numerical Relativity and Astrophysics

Throughout the Universe many powerful events are driven by strong gravitational effects that require general relativity to fully describe them. These include compact binary mergers, black hole accretion, and stellar collapse, where velociti...

Accretion power in astrophysics

Inference, Prediction, & Entropy-Rate Estimation of Continuous-Time, Discrete-Event Processes

Inferring models, predicting the future, and estimating the entropy rate of discrete-time, discrete-event processes is well-worn ground. However, a much broader class of discrete-event processes operates in continuous-time. Here, we provide...

To the question of foreign-language training of undergraduates of power specialities in technical establishments of higher education of Ukraine

In the article the current state of foreign linguistic preparation of future power-engineering specialists in technical institutions of higher education is investigated and analysed. On the basis of the theoretical review of scientific and ...
