Mediação cultural da informação para o reencantamento do mundo
Authors: Bezerra Arthur Coelho , Cavalcante Luciane de Fátima Beckman 
Published: September 2020

Objetivo: O presente artigo propõe discutir a implementação de práticas de mediação cultural da informação no âmbito do ensino e da pesquisa acadêmica, destacando a contribuição de tais práticas para a ampliação dos horizontes epistemológicos do pensamento científico. Tais objetivos se apoiam no reconhecimento do método científico como a forma mais arrojada de sistematização do conhecimento desenvolvida pela humanidade, porém em oposição à ideia de que o saber científico é o único portador de rigor e validade.Método: Iremos empreender uma pesquisa exploratória em torno dos conceitos de “mediação da informação” e “mediação cultural” (conforme pensado nos diálogos entre os estudos da informação e da comunicação social), amalgamando-os em uma noção de “mediação cultural da informação”. Posteriormente, a crítica aos usos da racionalidade da ciência moderna nas políticas de colonização servirá de mote para a defesa de sua aproximação com outras epistemologias e concepções de vida e mundo; nesse âmbito, a ideia de tradução surge como exemplo de prática de mediação cultural da informação.Resultado: Compreendemos que a perspectiva weberiana de “desencantamento do mundo” é resultante de uma racionalização das mais diferentes esferas da vida, processo que operou, na esteira da colonização de corpos e mentes, uma espécie de marginalização e apagamento de conhecimentos e saberes de povos tradicionais e de minorias ao redor do planeta. Conclusões: A adoção de práticas de mediação cultural da informação tem o condão de operar uma espécie de “reencantamento do mundo”, permitindo que o entendimento dos fenômenos investigados pela ciência não se dê exclusivamente no âmbito da racionalização instrumental dos processos do conhecer, mas, também, pelas singularidades e pluralidades construídas e reconstruídas a partir de trocas simbólicas no plano da cultura.

Abstract. The stain of wood samples from lake subfossil trees
(LSTs) is challenging the wide application of the blue intensity (BI)
technique for millennial dendroclimatic reconstructions. In this study, we
used seven chemical destaining reagents to treat samples of subfossil black
spruce (Picea mariana (Mill.) B.S.P.) trees from two lakes in the eastern Canadian boreal
forest. We subsequently compared latewood BI (LBI) and delta BI (DBI) time
series along with conventional maximum latewood density (MXD) measured from
the stained and destained samples. Results showed that the stain of our
samples is most likely caused by postsampling oxidation of dissolved
ferrous iron in lake sediments that penetrated into wood. Three reagents
(ascorbic acid, sodium ascorbate, and sodium dithionite all mixed with
ethylenediaminetetraacetic acid) could remove >90 % of Fe.
However, even for the best chemical protocol, a discrepancy of about
+2 ∘C compared to MXD data remained in the LBI-based temperature
reconstruction due to incomplete destaining. On the contrary, the simple
mathematical delta correction, DBI, was unaffected by the Fe stain and showed
very similar results compared to MXD data (r>0.82) from annual
to centennial timescales over the past ∼360 years. This study
underlines the difficulty of completely destaining lake subfossil samples while confirming the robustness of the DBI approach. DBI data measured from
stained LSTs can be used to perform robust millennial temperature
reconstructions.
Can the boundary profiles at 26° N be used to extract buoyancy-forced Atlantic Meridional Overturning Circulation signals?
Authors: Polo Irene , Haines Keith , Robson Jon , Thomas Christopher 
Published: September 2020

Abstract. The temporal variability of the Atlantic Meridional
Overturning Circulation (AMOC) is driven both by direct wind stresses and by
the buoyancy-driven formation of North Atlantic Deep Water over the Labrador Sea
and Nordic Seas. In many models, low-frequency density variability down the
western boundary of the Atlantic basin is linked to changes in the buoyancy
forcing over the Atlantic subpolar gyre (SPG) region, and this is found to
explain part of the geostrophic AMOC variability at 26∘ N. In this study,
using different experiments with an ocean general circulation model (OGCM), we develop statistical methods to
identify characteristic vertical density profiles at 26∘ N at the western and
eastern boundaries, which relate to the buoyancy-forced AMOC. We show that
density anomalies due to anomalous buoyancy forcing over the SPG propagate
equatorward along the western Atlantic boundary (through 26∘ N),
eastward along the Equator, and then poleward up the eastern Atlantic boundary.
The timing of the density anomalies appearing at the western and eastern
boundaries at 26∘ N reveals ∼ 2–3-year lags between boundaries
along deeper levels (2600–3000 m). Record lengths of more than 26 years are
required at the western boundary (WB) to allow the buoyancy-forced signals to appear as the
dominant empirical orthogonal function (EOF) mode. Results suggest that the depth structure of the signals
and the lagged covariances between the boundaries at 26∘ N may both provide
useful information for detecting propagating signals of high-latitude origin
in more complex models and potentially in the observational RAPID (Rapid Climate Change programme) array.
However, time filtering may be needed, together with the continuation of the
RAPID programme, in order to extend the time period.

ABSTRACT
Pythium insidiosum is an oomycete that encysts in the skin or gastrointestinal tract, leading to pythiosis. Pythiosis is reported in tropical and subtropical climates, affecting dogs and rarely cats. Surgical resection is the treatment of choice; however, cases present late in the disease and lesions are often nonresectable. Medical management is typically unsuccessful, with uncommon exceptions; however, mefenoxam, an agricultural fungicide, has in vitro efficacy against P insidiosum. We describe the use of mefenoxam, itraconazole, and terbinafine (MIT) in five dogs with gastrointestinal pythiosis and one dog with cutaneous pythiosis. Two of the gastrointestinal cases had disease extending to surgical margins and received MIT: resolution of clinical signs and seronegativity occurred after 189–193 days. Another case underwent surgical resection and MIT. The dog improved but subsequently developed a rectal mass, which responded to addition of prednisone and immunotherapy. Two cases were treated with MIT alone, and response varied. Efficacy of MIT in cutaneous pythiosis could not be determined. MIT may result in improved survival and seronegativity in dogs with incompletely resected gastrointestinal pythiosis. Mefenoxam is EPA registered, and extralabel use under the Animal Medicinal Drug Use Clarification Act does not apply. Additional research is recommended before use.

AbstractPurposeResults of a prospective, randomized controlled trial at our institute demonstrate an association between the dose to the left hippocampus and neurocognitive decline post‐radiotherapy for patients with glioblastoma. To minimize the dose to the left hippocampus, a left hippocampus sparing model was created using RapidPlan (RP) and multi‐criteria optimization (MCO).Materials and methodsFor 147 patients with newly diagnosed glioblastoma treated with volumetric modulated arc therapy (VMAT), the left and right hippocampus were delineated. Ninety‐seven of 147 VMAT plans were used to configure a RP model named HCS1. The remaining 50 VMAT plans were used for the model validation. All 97 plans were replanned with the HCS1 and further optimized using MCO (HCS1+MCO). MCO was used to explore the trade‐off between reducing the left hippocampus mean dose and planning objectives for the targets and other organs‐at‐risk (OAR) for HCS1 plans. These plans were used to create a new model called HCS2. MCO and RP model configuration were done within the Eclipse treatment planning system.ResultsThe final HCS2 model decreased the mean dose to the left hippocampus by 26% compared to clinically treated plans without reducing target coverage for 50 validation data. The mean dose to the left hippocampus decreased from 32.65 Gy in clinically treated plans, 30.45 Gy in HCS1‐generated plans, and 24.04 Gy in HCS2‐generated plans. The mean volume receiving 95% of the prescription dose (V95%) of the planning target volume was 99.08% ± 1.39% in clinically treated plans, 99.03% ± 1.37% in HCS1‐generated plans, and 98.80% ± 1.48% in HCS2‐generated plans. Mean dose to 0.1 cc of the brainstem improved from 45.91 Gy in clinically treated plans to 39.29 Gy in HCS2‐generated plans.ConclusionsThe RP model and MCO helps to decrease left hippocampus mean dose while maintaining the target volume coverage and OAR sparing comparable to clinically treated plans for glioblastoma patients.

Published: February 2025

Vanadium dioxide (VO2) is a well‐known candidate for memristor applications due to its insulator‐to‐metal transition (IMT) characteristics. The fabrication of memristor devices requires highly controlled synthesis processes concerning the material chemistry and geometry. Atomic layer deposition (ALD) offers unique advantages for the fabrication of hardware neural networks, such as miniaturization, conformality, and sub‐nm thickness control. Herein, an ALD process for non‐stoichiometric vanadium oxide (VOx) using tetrakis(dimethylamino)vanadium (TDMAV) and water as precursors is presented. Subsequently, a tailor‐made annealing process converts VOx into VO2, which exhibits an IMT of about three orders of magnitude at around 70 °C, rendering it a promising memristor material. VO2 thin film and Si–Al2O3/VO2 core/shell memristors are fabricated and analyzed, both of which exhibited I–V hysteresis loops, indicating their suitability for memristor applications in both 2D and 3D morphologies. Additionally, these memristors are sensitive to the operation temperature, with the hysteresis loops narrowing and shifting toward lower voltages as temperature increases, eventually disappearing beyond VO2's intrinsic phase transition temperature. This study highlights the viability of ALD‐assisted VO2 for memristor applications and demonstrates its potential for advancing the three‐dimensionalization of neuromorphic chips.

AbstractLithium‐ion (Li‐ion) batteries have become indispensable as the energy landscape shifts toward electrification. Enhancing their cycle life while ensuring optimal safety and performance is predicated on developing advanced thermal management approaches. Most battery thermal management systems rely on external temperature sensors, which do not reflect the true dynamic changes in internal temperatures, especially under operational extremes. This study utilizes a combination of operando thermal sensing and mechanistic modeling to investigate internal temperature evolution and associated thermo‐electrochemical interactions during Li‐ion cell cycling. Through this analysis, the non‐linear progression in cell temperature dynamics at various operating conditions and the underlying difference between the internal and external temperatures are captured. The internal temperature measurements reveal a critical asymmetry in the thermal response during charge and discharge operation, with a strong dependence on the current rate and operating temperature. In synergy with thermal sensing, a physics‐based modeling framework is developed to quantify different modes of heat generation within the cell layers and correlate them with the occurrence of degradation mechanisms, including lithium plating and solid electrolyte interphase interactions. This work provides the baseline for developing onboard diagnostic tools capable of detecting internal cell temperatures and monitoring cell safety through integrated thermal sensing and physics‐informed digital twins.

AbstractPhotodetectors (PDs) based on 2D transition metal dichalcogenides (2D TMDCs) heterojunction have become a potential candidate for frontier technology applications such as visible light communication (VLC). However, the conventional 2D TMDCs heterojunction PDs are facing problems with excessive dark current and low photoelectric conversion efficiency, resulting in the performance of PDs not meeting application requirements. Herein, the controllable growth of monocrystalline MoS2/polycrystalline ReS2 lateral heterojunction via a two‐step chemical vapor deposition (CVD) method has been proposed. According to the result of density functional theory (DFT) calculation and the characterization of multiple parallel experiments under different conditions, the controllable growth of lateral heterojunction, especially the competition mechanism between lateral epitaxy and vertical stacking is systematically analyzed from different perspectives. Based on the analysis above, a strategy for preparing monocrystalline MoS2/polycrystalline ReS2 lateral heterojunction with a large‐scale epitaxy layer and a high‐quality lateral structure is provided. Finally, PDs based on the as‐grown lateral heterojunction with responsivity and external quantum efficiency (EQE) up to 2.65 A W−1 and 506% are successfully applied to the VLC demonstration. This work provides a potential approach for the design and fabrication of optoelectronic devices with the requirement of high responsivity and photoelectric conversion efficiency.

Abstract2D lead halide perovskites (2DPs) offer chemical compatibility with 3D perovskites and enhanced stability, which are attractive for applications in photovoltaic and light‐emitting devices. However, such lowered structural dimensionality causes increased excitonic effects and highly anisotropic charge‐carrier transport. Determining the diffusivity of excitations, in particular for out‐of‐plane or inter‐layer transport, is therefore crucial, yet challenging to achieve. Here, an effective method is demonstrated for monitoring inter‐layer diffusion of photoexcitations in (PEA)2PbI4 thin films by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. Selective photoexcitation from either substrate‐ or air‐side of the films reveals differences in diffusion dynamics encountered through the film profile. Time‐dependent diffusion coefficients are extracted from spectral dynamics through a 1D diffusion model coupled with an interference correction for refractive index variations arising from the strong excitonic resonance of 2DPs. Such analysis, together with structural probes, shows that minute misalignment of 2DPs planes occurs at distances far from the substrate, where efficient in‐plane transport consequently overshadows the less efficient out‐of‐plane transport in the direction perpendicular to the substrate. Through detailed analysis, a low out‐of‐plane excitation diffusion coefficient of (0.26 ± 0.03) ×10−4 cm2 s−1 is determined, consistent with a diffusion anisotropy of ≈4 orders of magnitude.

AbstractThe brittle buried interface, characterized by weak adhesion to the substrate, numerous imperfections, and unfavorable strain, poses a significant challenge that impairs the overall performance and long‐term stability of perovskite solar cells (PSCs). Herein, a robust molecular zipper is constructed through in situ polymerization of self‐assembly monomer 4‐vinylbenzoic acid (VA), to tightly link the buried interface to the substrate in n‐i‐p PSCs with an adhesive strength as high as 10.77 MPa. The modified buried interface exhibits improved morphology, suppressed defects, released strain, and matched energy level alignment. The resulting PSCs deliver an absolute gain of ≥1.67% in champion power conversion efficiency based on both one‐step deposition protocol and two‐step one, demonstrating the universality of this strategy across different film‐processing scenarios. The unencapsulated PSCs can retain 94.2% of their initial efficiency after 550 h with a linear extrapolated T90 value of 1230 h, as per the ISOS‐L‐2 protocol. This work provides a facile strategy to reinforce the buried interface of PSCs.

AbstractReal‐time, high‐precision X‐ray imaging is of critical importance in a wide range of applications, from medical diagnostics to security screening. While lanthanide luminescent materials are among the most commonly used scintillators, achieving a combination of large‐area scalability, rapid response, and optimal performance remains challenging. Herein, a perovskite‐inspired cerium halide nanocrystal scintillator is presented with a remarkable photoluminescence quantum yield approaching unity and a fast radiative recombination rate of ≈29 ns. By leveraging these promising characteristics, large‐area X‐ray imaging is demonstrated with a spatial resolution of 12.21 lp mm−1 and an ultra‐low detection limit of 11.2 nGy s−1, alongside applications in dynamic imaging. Based on these paternal nanocrystals, the versatile spectral tunability through halide alloying and cation doping is further explored, offering a promising platform for future chemical and structural design toward advanced scintillations and other down‐conversion applications.

AbstractHigh and balanced open‐circuit voltage (VOC) and short‐circuit current density (JSC) are crucial for the efficiency of organic solar cells (OSCs). Generally, the π‐bridge strategy serving as an effective molecular functionalization route with the potential to balance the VOC‐JSC pair. Herein, the study designs and synthesizes three non‐fused ring electron acceptors (NFREAs): 2T‐T‐EH, 2T‐T‐2EH, and 2T‐TT‐2EH, by systematically regulating the π‐bridge at size, number, and position of the lateral alkyl chains. Introducing inner alkyl side chains result in twisted backbones, which elevated the lowest unoccupied molecular orbital (LUMO) energy levels, and reduced energy loss, facilitating a higher VOC. Single crystal analysis also reveals that the π‐extending in 2T‐TT‐2EH can effectively relieve the congestion of dual lateral chains, leave more space for the terminal overlapping, which promotes efficient charge transport and enhancing JSC. Consequently, a compromise between VOC (0.916 V) and JSC (21.21 mA cm−2) is accomplished in the binary OSCs. The elevated LUMO energy level and VOC provides 2T‐TT‐2EH to serve as a third component in ternary OSCs, achieving an impressive power conversion efficiency (PCE) of 19.07% in the D18:BTP‐eC9‐4F:2T‐TT‐2EH‐based device. These findings in this study suggest that fine‐tuning the π‐bridges is a simple method for optimizing photovoltaic performance in NFREAs, ensuring a well‐balanced VOC and JSC.

AbstractThe interaction of very low frequency (VLF) and extremely low frequency (ELF) electromagnetic waves with nanocomposites is rarely explored. It is demonstrated that low‐dimensional electrically conducting fillers are able to shield extremely long wavelengths, provided they form extended conduction paths through percolation. Other mechanisms that synergistically augment the shielding of the high frequencies, such as skin effect, interfacial polarization, and multiple internal scattering, have insignificant effects in the low‐frequency range. In this regard, high aspect ratio 1D conductors having the lowest percolation thresholds provide the best shielding performance, both gravimetrically and volumetrically. Shielding in these materials are observed majorly occur mostly through reflection, and hence, these materials can be employed for both shielding and guiding low frequencies. The correlation proposed to estimate shielding effectiveness based on conductivity and frequency enables convenient material design for low‐frequency modulation.
