Notes on krondirs, an interesting type of Late Medieval tin-and-lead vessels

open access: yesПриноси към българската археология, 2022
The paper presents and analyses the earliest evidence available to date about a specific type of tin-andlead vessel used to store water and wine, and perhaps myrrh, known as “krondirs”.

Robotic Assistants in the Operating Room: A Systematic Review of Vision‐Based Systems for Nonoperative Tasks

open access: yesAdvanced Robotics Research, EarlyView.
This review brings together 20 publications describing 11 robotic system families developed for instrument handling, sterile‐package opening, supply delivery, and operating room logistics. Perception is becoming more capable through deep learning and language‐guided control, but autonomy remains limited, evidence is largely laboratory‐based, and no ...

La transformation numérique : quelques procès en cours

open access: yesRevue Française des Sciences de l’Information et de la Communication, 2013
In this paper we try to examine a number of requisites for a "general theory of narrative" and to consider some difficulties, particularly of the semiotic order, in connection with the great digital transformation.

Runaway brain‐culture coevolution as a reason for larger brains: Exploring the “cultural drive” hypothesis by computer modeling

open access: yesEcology and Evolution, 2020
Scale and tempo of brain expansion in the course of human evolution implies that this process was driven by a positive feedback. The “cultural drive” hypothesis suggests a possible mechanism for the runaway brain‐culture coevolution wherein high‐fidelity

Perioperative management of patients with drug addiction

open access: yesМедицина неотложных состояний, 2023
Background. Patients undergoing surgical or diagnostic procedures, as well as critically ill patients, often suffer from psychoactive substance use disorders. The term “psychoactive substances” here includes both narcotics and psychotropic substances (or

Markov constraints: steerable generation of Markov sequences [PDF]

open access: yesConstraints, 2010
Markov chains are a well known tool to model temporal properties of many phenomena, from text structure to fluctuations in economics. Because they are easy to generate, Markovian sequences, i.e. temporal sequences having the Markov property, are also used for content generation applications such as text or music generation that imitate a given style ...

Robotics in Ionizing Radiation Environments: Vulnerabilities, Hardening, and Future Directions

open access: yesAdvanced Robotics Research, EarlyView.
Radiation exposure causes cumulative degradation in robotic sensors, actuators, and electronic logic, often leading to undetected failures. This study maps component vulnerabilities, evaluates hardening and shielding strategies, and identifies testing gaps that must be addressed to enable next‐generation radiation‐tolerant robotic systems.

Uso de las cadenas de Markov para un modelo de negocios

open access: yesInnova Research Journal, 2017
Predecir las ventas de un producto de una industria resulta un problema matemático significante para los negocios, fundamentalmente en la producción de sábila como materia prima, todo está expuesto a riesgos debido a malos cálculos por parte de los ...

Compositional Approximate Markov Chain Aggregation for PEPA Models [PDF]

open access: yes, 2012
Approximate Markov chain aggregation involves the construction of a smaller Markov chain that approximates the behaviour of a given chain. We discuss two different approaches to obtain a nearly optimal partition of the state-space, based on different ...

Charting Endocrine Progenitors Across Species and Organs

open access: yesAdvanced Science, EarlyView.
Endocrine progenitors give rise to the hormone‐producing cells of the pancreas and intestine. Using single‐cell multiomics and proteomics, this study compares these progenitors across species, systems, and organs, mapping the conserved and species‐specific gene regulatory networks that guide their formation.
