Contornos e desafios da diversificação produtiva em áreas de cultivo de tabaco entre jovens rurais no território gaúcho

The tobacco production and productive diversification have gained ground and generated controversy in the contemporary challenges of rural development. In this sense, the article aims, from the reality of two cities in the state, the Tiger Brook and São Lourenço do Sul, to analyz...

Predatory nematodes associated with polyhouse grown flower crops in Himachal Pradesh

Four predatory nematodes (mononchids) viz., Mylonchulus (M. brachyuris), Iotonchus (I. monhystera), Mononchus (M. truncatus) and Clarkus (C. papillatus) were found harbouring the rhizosphere of flower crops (carnation, rose and chrysanthemum), along with plant parasitic nematodes...

Sustainable crop removal: Maintaining soil quality

Agricultural biomass, the aboveground plant material that is not grain, is being looked to as a promising renewable energy source for heat and power, ethanol, syngas and bio-oil. When used for these purposes biomass is often referred to being a cellulosic bioenergy feedstock. Cur...

The Human Experience System: A Transdisciplinary Model of Embodied Human Experience for Clinical Science and Computational Therapeutics

Current models of human experience used in clinical science — the biopsychosocial model (Engel, 1977), categorical diagnostic systems (DSM-5-TR; APA, 2022; ICD-11; WHO, 2019), and dimensional frameworks (RDoC; Insel et al., 2010) — share four critical absences: no model treats th...

Planetary Common State (PCS): A Testable Common Macroscopic State Representation for Coupled Earth-Civilization Systems

Planetary-scale questions frequently involve interactions among geophysical, biological, infrastructural, and informational processes that are modeled in different variables, units, resolutions, and disciplinary frameworks. This paper formulates Planetary Common State (PCS) as a...

The Statistical Bridge

A business asks for average revenue per active customer this quarter, with a standard error. The analyst has login events, transaction events, customer identifiers, and a familiar formula. Every arithmetic step can be correct while the analysis has not established what one custom...

Essential Writings: Five Decades of Research in Seismic Exploration

This preprint presents a curated collection of selected works spanning more than five decades of research in seismic exploration, from the late 1970s to 2026. The collection covers reflected-wave kinematics, travel-time field derivatives, velocity estimation, seismic data process...

Where Does Probability Live?

The frequentist-Bayesian divide is usually introduced as a dispute about the meaning of probability, the status of parameters, priors, repeated sampling, or the interpretation of intervals. Those disagreements are real, but they begin after an earlier statistical problem has alre...

Certifiable State Under Information Loss

Data systems routinely transform state without preserving everything that made the state analytically trustworthy. This paper introduces a governed-state object, K=(K,Γ,E), and a proof-relevant graded derivability judgment, K⊩gc, to distinguish operational information from what a...

Economics of seed production in carrot as influenced by spacing, steckling size and umbel order

The present study was carried out at UTP, Habak, Division of Vegetable Science, SKUAST-Kashmir during 2013-14 to standardize the mother root size, spacing and umbel order to improve seed production in carrot for maximizing economic returns. The economics of different inputs and r...

Agricultura Familiar y Agroindustrias: subordinación productiva. Los casos de la citricultura y la fruticultura de Argentina (2003-2016)

This article proposes to investigate the link between family farming (AF) and agro-industries. The research is based on a qualitative methodology and uses quantitative information. In particular, two cases (citric belt of Middle Uruguay River and fruit growing of Patagonic Valley...

Sucessão ecológica, entropia e o Modelo Autonomia-Heteronomia para análise dos sistemas agrícolas

It is proposed a agronomic analytical model, Autonomy-Heteronomy, for description and analysis of agricultural systems. Autonomous systems are characterized by preferential use of local resources and strategies to meet local or regional needs. They are systems of low entropy and...

Agroecologia e a ética da inovação na agricultura

Capitalism makes impossible ethical conviviality among all living beings. Constituted by a global power pattern —Coloniality— that acts upon race, knowing, being, nature, the capitalist institutionality is hostile to ethics for it conflicts with practices —patriarchal, racial, et...

Agroecologia e mudanças climáticas no Trópico Semiárido

This article makes a theoretical and, to a certain extent, propositional reflection on the conceptions, assumptions and evidences of climate change in the tropics, with emphasis on the Brazilian semiarid region. The contributions of agriculture to climate change are presented and...

Agroecologia: princípios e estratégias para o desenho de agroecossistemas sustentáveis

The theme of this paper is the debate on principles and strategies for designing sustainable agricultural systems. The paper builds on a broad approach to principles, moving to the more specific approach to strategies and finalizing with a micro-scale perspective on the practice...

Agroecologia e Economia Solidária: um diálogo necessário à consolidação do direito à soberania e segurança alimentar e nutricional

This article aims to analyze the practices of agroecology and solidarity economy movements in the conquest of the right to food and nutritional sovereignty and security. These movements not always have the same strategy, complement each other by acting in different territories to...

Metodologias Participativas em Agroecologia: redes, processos e estratégias rumo a uma Pedagogia do Alimento

This article, based on a theoretical and methodological approach, starts from the criticism made by the New Philosophy of Science and its influence on the Liberating Education in Brazil and Latin America, highlighting the growing relationship of popular participation and Agroecol...

Ediacaran coupling of climate and biosphere dynamics

Climate change is demonstrably linked to radiations, extinctions, and turnovers in the biosphere throughout the Phanerozoic (538.8 Ma to present). Here, we suggest this connection existed as early as the late Ediacaran (ca. 579−538.8 Ma), the first interval in Earth’s history to...

dynoGP: Deep Gaussian Processes for Dynamic System Identification

ABSTRACT In this work, we present a novel approach to system identification for dynamical systems, based on a specific class of deep Gaussian processes (deepGPs). These models are constructed by interconnecting linear dynamic GPs (equivalent to stochastic linear time‐invariant dy...

Accurate quantification of spliced and unspliced transcripts for single-cell RNA sequencing with tidesurf

Abstract Motivation Single-cell RNA sequencing (scRNA-seq) allows for the detailed analysis of dynamic cellular processes. In particular, this has been enabled by the estimation of RNA velocity, the derivative of gene expression, from separate count matrices for different splice...
