Nanoscale sensing of spatial correlations in nonequilibrium current noise

Abstract Nitrogen-vacancy centers are spatially resolved probes of current noise. So far, current noise sensing with NV centers has primarily been used as a way to probe equilibrium transport coefficients. We develop a framework for computing the spatiotemporal correlations of no...

Direct search for stochastic optimization in random subspaces with zeroth-, first-, and second-order convergence and expected complexity

Abstract Stochastic directional direct-search (SDDS) algorithms were recently introduced as an extension to stochastically noisy objectives of a broad class of algorithms including the well-known mesh adaptive direct-search (MADS) algorithms developed for the minimization of dete...

Reducing the diagnostic and treatment gap for priority mental, neurological and substance misuse disorders in primary care in rural Kenya: Results of a stepped wedge cluster randomized trial from the EPINA study

ABSTRACTBackground: In resource-limited settings, care for mental, neurological and substance misuse (MNS) disorders has been integrated into primary healthcare facilities (PHC) by training primary health workers (PHW) on the use of the mental health Gap Action Program Interventi...

The regular part of transformation semigroups that preserve double direction equivalence relation

Let $T(X)$ be the full transformation semigroup on a set $X$ under the composition of functions. For any equivalence relation $E$ on $X$, define a subsemigroup $T_{E^*}(X)$ of $T(X)$ by\[T_{E^*}(X)=\{\alpha\in T(X):\text{for all}\ x,y\in X, (x,y)\in E\Leftrightarrow (x\alpha,y\al...

Maximum Likelihood Thresholds of Generic Linear Concentration Models

Abstract. The maximum likelihood threshold of a statistical model is the minimum number of datapoints required to fit the model via maximum likelihood estimation. In this paper, we determine the maximum likelihood thresholds of generic linear concentration models. This turns out...

RKHS-Based Latent Position Random Graph Correlation

We study the problem of evaluating the correlation between two latent position random graphs, which is a challenging issue because the latent positions are generally unobservable in random graphs. We introduce a correlation coefficient that is defined in the reproducing kernel Hi...

Population parameters and life fertility table of root- knot nematode (Meloidogyne incognita) on cauliflower (Brassica oleracea var. botrytis)

The study was conducted under growth chamber at the Department of Entomology, College of Horticulture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh during 2015-16 to developed the life fertility table of M. incognita on cauliflo...

Dependence of Hurricane Track Forecasts on the Spectral Representation of Cumulus Convection

This study investigates the sensitivity of hurricane track and intensity forecasts to various cumulus parameterization schemes with scale-awareness, including the Simplified Arakawa-Schubert (SAS), Relaxed Arakawa-Schubert (RAS), and Chikira-Sugiyama Arakawa-Wu (CSAW), within the...

As arenas de Construção do Conhecimento Agroecológico como espaços para emergência de um “novo profissionalismo” da ação extensionista.

The present text approaches the transition that the professionals of the Technical Assistance and Rural Extension in Brazil points out, through the analysis of the experience of Dom Feliciano-RS, the possibility of the emergence of a space of change from a diffusionist perspectiv...

Juventudes Rurais e Agroecologia: um diálogo imprescindível

Arguments from different areas of knowledge (Economics, Philosophy, Sociology, among others) point to a civilization crisis experienced by humanity in our day. In order to solve this crisis, it is necessary to mobilize different social and political actors, many of them invisibil...

Economia ecológica: uma possível referência para o desenho de sistemas humanos realmente sustentáveis

In the prevailing model of the typical economist, the economy is seen as an isolated system, without an environment, ignoring the ecosystem, the biophysical framework of the real economic system. It ignores the importance of happiness for social life as well. In fact, people are...

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...
