An Improved Separation of Regular Resolution from Pool Resolution and Clause Learning [PDF]

open access: yes, 2012
We prove that the graph tautology principles of Alekhnovich, Johannsen, Pitassi and Urquhart have polynomial size pool resolution refutations that use only input lemmas as learned clauses and without degenerate resolution inferences.

Sistema do sistema

open access: yesVeritas (Porto Alegre), 2013
Toda filosofia é sistemática, se por “sistema” entendemos a vontade de exibir um pensamento consistente, dando a toda humanidade a medida do que ela é capaz, e impulsionando, assim, os animais humanos a situarem seus atos para além dos limites que ordinariamente eles infligem-se. Porém, há um outro sentido, mais litigioso, da noção de sistema.

Data‐Driven Review and Machine Learning Prediction of Diamond Vacancy Center Synthesis

open access: yesAdvanced Intelligent Systems, EarlyView.
A machine learning framework is applied to photoluminescence spectra to extract linewidths and uncover how NV, SiV, GeV, and SnV centers evolve with growth and processing conditions. Unified normalization and k‐fold validation reveal cross‐method trends and enable rapid prediction of defect size and fabrication parameters, offering a data‐driven route ...

Edukologijos Sistema

open access: yesActa Paedagogica Vilnensia, 1999
Nors pastaruoju metu pasirodė nuodugnių edukologijos objekto ir sistemos tyrimų, verta dar kartą pažvelgti į tai, ką iš esmės tiria edukologai, ar tyrimo rezultatai gali būti vadinami mokslu, kokia to mokslo sistema. Taigi mums rūpi edukologijos dalykas, jos sistema. Čia bus siekiama rasti atsakymą tiems, kas abejoja edukologijos moksline verte.

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Synergetic Combination of Carbon Xerogels, Graphene Oxide and nano‐ZnO for Aqueous and Organic Supercapacitors

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This work proposes the synthesis of carbon‐based nanostructured materials obtained using ZnO as both nanos‐ template and catalysts simultaneously. During the synthesis, GO was used as a stabiliser, preventing the collapse of the 3D structure and improving its properties in terms of capacitance and surface area.

Tuning the Twist by Molecular Design: A New Strategy for Hexabenzocoronene‐Containing Helical Twistacene

open access: yesChemistry – A European Journal, EarlyView.
An efficient Scholl–based strategy enables precise control of the C–C bond to access the first hexabenzocoronene–containing helical twistacene (NG2). The resulting nanographene shows pronounced helical distortion, high stability, enhanced solubility, and promising redox and optoelectronic properties.
