THE IMPACTS OF MACROECONOMIC CHANGES ON AGRICULTURAL CREDIT RISK IN BRAZIL
Creators: Tanaka, Henrique Rafael Barboza Costa
Publisher: name: University of Alberta Library
Year: 2023

This paper analyses the relationship between macroeconomic variables (gross domestic product, unemployment rate, public debt and balance of international investments) and credit risk, measured as non-performing loans—or credit default. This study uses quarterly data for macroeconomic variables and rural credit default for the Brazilian banking system from 2012 to 2022. The study finds that deterioration in macroeconomic conditions, such as GDP and unemployment, will increase agricultural credit risk. At the same time, positive changes, like a reduction in the balance of international investments' deficit, reduced credit risk levels. The research methodology involves a Vector autoregression (VARX) technique and Impulse Response Functions (IRFs). This study's findings can contribute to the existing literature on the relationship between macroeconomic variables and credit risk and provide insights for policymakers and financial institutions while addressing rural credit risk models.

description: We explore the formation of Wigner crystals for charged particles on a toroidal helix. Focusing on certain commensurate cases we show that the ground state undergoes a pitchfork bifurcation from the totally symmetric polygonic to a zig-zag-like configuration with increasing radius of the helix. Remarkably, we find that for a specific value of the helix radius, below the bifurcation point, the vibrational frequency spectrum collapses to a single frequency. This allows for an essentially independent small-amplitude motion of the individual particles and consequently localized excitations can propagate in time without significant spreading. Increasing the radius beyond the degeneracy point, the band structure is inverted, with the out-of-phase oscillation mode becoming lower in frequency than the mode corresponding to the center of mass motion.

description: Nel Diario di Grecia di Lalla Romano, frutto di un viaggio compiuto dalla scrittrice in compagnia del marito nel 1957, la dimensione soggettiva pre vale sulla descrizione oggettiva dei luoghi visitati: non siamo tanto di fronte a letteratura odeporica quanto a pagine di un diario in cui l’io riporta, come notò Montale, la sua «confessione privata». La Grecia rappresenta, per Romano, sia il diverso (i paesaggi marini, rocciosi e assolati, sono asso luta alterità per lei abituata alle montagne cu neesi) che l’identico: inaspettatamente, nei luoghi visitati lo sguardo coglie tracce di ciò che è già stato vissuto. La Grecia «toccata con mano» si so vrappone, con effetto perturbante, alla Grecia-li bro in cui affondano le radici culturali della scrit trice: durante il viaggio si lacera, non senza cau sare dolore, l’immagine della Grecia di carta, per far posto a una Grecia di pietra, solida e concreta, dalla «bellezza nutrita di pane».
description: In Lalla Romano's Diario di Grecia, written after a author’s trip to Greece with her husband in 1957, the subjective dimension prevails over the objective description of the locations she visited: we are not so much faced with travel literature as with the pages of a diary where, as noted by Mon tale, the author reports her private confessions. For Romano, Greece represents both the different (the seascapes, rocky and sunny, are an absolute otherness for her, compared to the mountains of Cuneo) and the identical: unexpectedly, in the lo cation she visited, the author sees traces of events she has already experienced. Seen up close Greece overlaps with the Greece represented in the books, where the author's cultural roots are found: dur ing the journey the image of bookish Greece is torn apart, not in a unpainful way, to give space for a Greece made of stone, solid, whose beauty, says Romano, is as real as bread.

description: Introduction : Lors du diagnostic de cancer, les patients doivent prendre des décisions quant aux traitements. Des conséquences néfastes pourraient s’en suivre car ils n’ont pas les outils en main pour y faire face et se sentent démunis. Objectif : Identifier les interventions infirmières qui favoriseraient la prise de décision des patients atteints de cancer concernant leur traitement médical à l’annonce du diagnostic. Méthode : Les bases de données sont Medline et CINHAL. Sept articles choisis entre 2004 et 2014, avec une population adulte récemment diagnostiquée pour un cancer, ont été analysés à l’aide de la grille de Fortin. Les thèmes issus des différentes études, ont été classés selon les concepts de la théorie intermédiaire de Meleis. Résultats : Les principaux résultats s’inscrivent sous les propriétés de la personne, les conditions facilitantes ou entravantes et communautaires. Les interventions infirmières sont : un dialogue ouvert, interactif et le soutien du patient par le soignant ; l’éducation du patient : la préparation ainsi que l’accès aux informations concernant le cancer ; la mise en place d’un outil d’aide à la décision ; augmentation de l’accès aux soins pour les régions défavorisées. Elles seraient des facteurs facilitants la prise de décision concernant le traitement médical. Conclusion : Un nombre restreint d’articles existent sur ce sujet. Les études ont mis en valeur la nécessité d’un accompagnement infirmier précoce après la pose du diagnostic de cancer pour favoriser les sentiments positifs chez les patients.

description: Introduction : L’association de certaines molécules des traitements antirétroviraux VIH/SIDA est connue pour provoquer la lipodystrophie. Les études démontrent que cet effet secondaire engendre une perturbation de l’image de soi et de la qualité de vie. Objectif : Le présent travail vise à définir les interventions que l’infirmière peut proposer à cette population dans le but d’améliorer l’image de soi en lien avec la qualité de vie. Le modèle d’adaptation de Roy servira de cadre théorique. Méthode : Deux bases de données ont été utilisées : CINHAL et PUBMED. Cinq articles quantitatifs et qualitatifs ont été retenus allant de 2005 à 2015. Résultat : Les liens entre la lipodystrophie, l’image corporelle et la qualité de vie sont clairement démontrés. Les interventions d’évaluation, de diététique, l’entretien motivationnel et la thérapie cognitive semblent être efficaces pour soutenir le concept de soi et la qualité de vie des patients VIH/SIDA atteints de lipodystrophie. Discussion : Le nombre restreint d’articles utilisés est une limite. Le concept clé du travail a également été un frein. En effet, les interventions au niveau de l’image de soi sont encore peu travaillées dans le domaine du VIH/SIDA et de la lipodystrophie. Il est primordial d’effectuer une évaluation par des échelles ou questionnaires à fin de détecter la lipodystrophie de façon précoce et son impact. Des interventions diététiques devraient être combinées à des entretiens motivationnels afin de maximiser l’adaptation positive dans le mode du concept de soi.

description: Determining the habitability and interpreting atmospheric spectra of exoplanets requires understanding their atmospheric physics and chemistry. We use a 3-D Coupled Climate-Chemistry Model, the Met Office Unified Model with the UK Chemistry and Aerosols framework, to study the emergence of lightning and its chemical impact on tidally-locked Earth-like exoplanets. We simulate the atmosphere of Proxima Centauri b orbiting in the Habitable Zone of its M-dwarf star, but the results apply to similar M-dwarf orbiting planets. Our chemical network includes the Chapman ozone reactions and hydrogen oxide (HO$_{\mathrm{x}}$=H+OH+HO$_2$) and nitrogen oxide (NO$_{\mathrm{x}}$=NO+NO$_2$) catalytic cycles. We find that photochemistry driven by stellar radiation (177-850 nm) supports a global ozone layer between 20-50 km. We parameterise lightning flashes as a function of cloud-top height and the resulting production of nitric oxide (NO) from the thermal decomposition of N$_2$ and O$_2$. Rapid dayside convection over and around the substellar point results in lightning flash rates of up to 0.16 flashes km$^{-2}$yr$^{-1}$, enriching the dayside atmosphere below altitudes of 20 km in NO$_{\mathrm{x}}$. Changes in dayside ozone are determined mainly by UV irradiance and the HO$_{\mathrm{x}}$ catalytic cycle. ~45% of the planetary dayside surface remains at habitable temperatures (T$_{\mathrm{surf}}$>273.15 K) and the ozone layer reduces surface UV radiation levels to 15%. Dayside-nightside thermal gradients result in strong winds that subsequently advect NO$_{\mathrm{x}}$ towards the nightside, where the absence of photochemistry allows NO$_{\mathrm{x}}$ chemistry to involve reservoir species. Our study also emphasizes the need for accurate UV stellar spectra to understand the atmospheric chemistry of exoplanets.

description: Introduction L’image est au coeur de la radiologie. Elle y est fabriquée, traitée, commentée et interprétée. Le technicien en radiologie médicale (TRM) y est sans cesse confronté. Cette étude a pour objectif de tracer un portrait général du rapport des TRM aux images. Méthodologie Six entretiens semi-directifs individuels ont été effectués auprès de TRM dans tous les secteurs de la radiologie à l’aide d’un guide d’entretien basé sur quatre dimensions: représentations, attrait et émotions, attitudes, fonction. Lors de ces entretiens, l’interprétation des images a été aussi étudiée en confrontant les participants à cinq images radiologiques. Résultats L’attirance des TRM pour les images radiologiques varie fortement selon le secteur dans lequel ils travaillent. Cet attrait se traduit par de l’impatience et du plaisir à découvrir ces images. Certaines émotions peuvent également être vectorisées par les images. Emotions qu’une partie des TRM ont déclaré avoir du mal à gérer. Parfois, de la méfiance envers l’image ou un regard désapprobateur envers sa beauté ont été mis en évidence. Les représentations des TRM dépendent du niveau de familiarisation avec les images et du type de patient imagé. Les avis sur la représentation de la réalité que peut avoir une image radiologique se sont révélés contrastés. On retrouve un langage propre aux TRM pour la décrire. L’image radiologique cache différentes fonctions, parfois surprenantes. Conclusion Notre étude met en lumière la grande complexité du rapport liant les TRM aux images. Elles semblent influencer les représentations, les émotions et les attitudes du professionnel.

description: Based on the mathematical arguments formulated within the Multifractal Detrended Fluctuation Analysis (MFDFA) approach it is shown that in the uncorrelated time series from the Gaussian basin of attraction the effects resembling multifractality asymptotically disappear for positive moments when the length of time series increases. A hint is given that this applies to the negative moments as well and extends to the Lévy stable regime of fluctuations. The related effects are also illustrated and confirmed by numerical simulations. This documents that the genuine multifractality in time series may only result from the long-range temporal correlations and the fatter distribution tails of fluctuations may broaden the width of singularity spectrum only when such correlations are present. The frequently asked question of what makes multifractality in time series - temporal correlations or broad distribution tails - is thus ill posed. In the absence of correlations only the bifractal or monofractal cases are possible. The former corresponds to the Lévy stable regime of fluctuations while the latter to the ones belonging to the Gaussian basin of attraction in the sense of the Central Limit Theorem.

description: We simulate an equal-mass merger of two Milky Way-size galaxy discs with moderate gas fractions at parsec-scale resolution including a new model for radiative cooling and heating in a multi-phase medium, as well as star formation and feedback from supernovae. The two discs initially have a $2.6\times10^6\mathrm{~M_{\odot}}$ supermassive black hole (SMBH) embedded in their centers. As the merger completes and the two galactic cores merge, the SMBHs form a a pair with a separation of a few hundred pc that gradually decays. Due to the stochastic nature of the system immediately following the merger, the orbital plane of the binary is significantly perturbed. Furthermore, owing to the strong starburst the gas from the central region is completely evacuated, requiring $\sim10$~Myr for a nuclear disc to rebuild. Most importantly, the clumpy nature of the interstellar medium has a major impact on the the dynamical evolution of the SMBH pair, which undergo gravitational encounters with massive gas clouds and stochastic torquing by both clouds and spiral modes in the disk. These effects combine to greatly delay the decay of the two SMBHs to separations of a few parsecs by nearly two orders of magnitude, $\sim 10^8$ yr, compared to previous work. In mergers of more gas-rich, clumpier galaxies at high redshift stochastic torques will be even more pronounced and potentially lead to stronger modulation of the orbital decay. This suggests that SMBH pairs at separations of several tens of parsecs should be relatively common at any redshift.

description: We map out the critical velocity in the crossover from Bose-Einstein condensation (BEC) to Bardeen-Cooper-Schrieffer superfluidity with ultracold $^{6}$Li gases. A small attractive potential is dragged along lines of constant column density. The rate of the induced heating increases steeply above a critical velocity $v_c$. In the same samples, we measure the speed of sound $v_s$ by exciting density waves and compare the results to the measured values of $v_c$. We perform numerical simulations in the BEC regime and find very good agreement, validating the approach. In the strongly correlated regime, where theoretical predictions only exist for the speed of sound, our measurements of $v_c$ provide a testing ground for theoretical approaches.

description: But du travail : Les lettres de plaintes écrites par les patients représentent une source d’information sur le vécu des patients lors de leur passage dans un service de radiologie, vécu qui lui est peu connu par les TRM. Le but de notre étude est d’identifier les motifs de plainte ou doléance des patients et de comprendre les contextes qui favoriseraient l’insatisfaction des patients. Méthodologie : Des lettres de plainte provenant de deux services de radiologie en Suisse romande ont été analysées afin d’identifier le motif et les circonstances qui ont occasionné la plainte. Cette analyse a été complétée par trois entretiens semi-dirigés. Résultats : En radiodiagnostic, les lettres de plainte sont peu fréquentes et les TRM ne sont pas systématiquement informés de leur contenu. Les motifs prépondérants des doléances des patients sont, avec 24% les dégâts matériels tels l’oubli d’objets de valeur ou d’argent, et avec 21% les transmissions d’informations et les problèmes organisationnels (retards, perte de dossiers radiologiques). Suivent ensuite les questions relatives à la radioprotection et les gestes techniques (pose de voie veineuse, biopsie). Conclusion : Les lettres de plainte sont une source pertinente pour la mise en oeuvre des actions d’amélioration de la qualité. Des changements ont été constatés lorsque les infrastructures ou certaines procédures étaient mises en cause. En tant que source sur le vécu du patient, ces lettres peuvent donner des informations importantes pour la formation des TRM. Nous proposons de communiquer le contenu de ces lettres avec plus de transparence.

description: There are, by now, several arguments that superstrata, which represent D1-D5-P bound states that depend upon arbitrary functions of two variables and that preserve four supersymmetries, exist in string theory, and that their gravitational back-reaction results in smooth horizonless solutions. In this paper we examine the shape and density modes of the superstratum and give strong evidence that the back-reacted supergravity solution allows for fluctuation modes whose quantization reproduces the entropy growth of black holes as a function of the charges. In particular, we argue that the shape modes of the superstratum that lie purely within the non-compact space-time directions account for at least $1/\sqrt{6}$ of the entropy of the D1-D5-P black hole and propose a way in which the rest of the entropy could be captured by superstratum fluctuations. We complete the picture by conjecturing a relationship between bound states of multiple superstrata and momentum excitations of different twisted sectors of the dual CFT.

description: Accurate predictions of inclusive scattering cross sections in the linear response regime require efficient and controllable methods to calculate the spectral density in a strongly-correlated many-body system. In this work we reformulate the recently proposed Gaussian Integral Transform technique in terms of Fourier moments of the system Hamiltonian which can be computed efficiently on a quantum computer. One of the main advantages of this framework is that it allows for an important reduction of the computational cost by exploiting previous knowledge about the energy moments of the spectral density. For a simple model of medium mass nucleus like $^{40}$Ca and target energy resolution of $1$ MeV we find an expected speed-up of $\approx 125$ times for the calculation of the giant dipole response and of $\approx 50$ times for the simulation of quasi-elastic electron scattering at typical momentum transfers.

description: Homophily is a significant mechanism for link prediction in complex network, of which principle describes that people with similar profiles or experiences tend to tie with each other. In a multi-relationship network, friendship among people has been utilized to reinforce similarity of taste for recommendation system whose basic idea is similar to homophily, yet how the taste inversely affects friendship prediction is little discussed. This paper contributes to address the issue by analyzing two benchmark datasets both including user's behavioral information of taste and friendship based on the principle of homophily. It can be found that the creation of friendship tightly associates with personal taste. Especially, the behavioral information of taste involving with popular objects is much more effective to improve the performance of friendship prediction. However, this result seems to be contradictory to the finding in [Q.M. Zhang, et al., PLoS ONE 8(2013)e62624] that the behavior information of taste involving with popular objects is redundant in recommendation system. We thus discuss this inconformity to comprehensively understand the correlation between them.

description: In the present work, we study the periodicities of oscillations in dark fine structures using observations of a network and a semi-active region close to the solar disk center. We simultaneously obtained spatially high resolution time series of white light images and narrow band images in the H$α$ line using the 2D Göttingen spectrometer, which were based on two Fabry-Perot interferometers and mounted in the VTT/Observatorio del Teide/Tenerife. During the observations, the H$α$ line was scanned at 18 wavelength positions with steps of 125 mÅ. We computed series of Doppler and intensity images by subtraction and addition of the H$α$ $\pm$ 0.3 Å and $\pm$ 0.7 Å pairs, sampling the upper chromosphere and the upper photosphere, respectively. Then we obtained power, coherence and phase difference spectra by performing a wavelet analysis to the Doppler fluctuations. Here, we present comparative results of oscillatory properties of dark fine structures seen in a network and a semi-active region.

THE IMPACT OF EMPOWERED WORLD VIEW ON REDUCING CHILD  STUNTING
Creators: Bebwa, Akiza Nasson
Publisher: name: University of Alberta Library
Year: 2023

This research examines the effectiveness of the Empowered World View (EVW) program in Kigoma and Iringa regions of Tanzania, focusing on reducing child stunting. The program aimed to empower women and safeguard maternal care and nutrition, promoting positive cultural behaviors to protect the rights of mothers and children. The study employed a Difference in Difference approach to investigate the impact of the program in reducing child stunting. The results indicate a notable decrease in the odds of child stunting among those who received the EVW treatment, with an overall Average Treatment Effect on the Treated (ATT) of -1.072 at 95% CI and a p-value of less than 0.01. This suggests that children participating in the EVW program had a 1.072 times lower likelihood of experiencing stunting compared to their non-intervention counterparts. These findings underscore the significance of the EVW program in combating child stunting while shedding light on key determinants that require attention for effective public health interventions.

description: Mixtures of light elements with heavy elements are important in inertial confinement fusion and planetary science. We explore the physics of molecular scale mixing through a validation study of equation of state (EOS) properties. Density functional theory molecular dynamics (DFT-MD) at elevated-temperature and pressure is used to obtain the thermodynamic state properties of pure xenon, ethane, and various compressed mixture compositions along their principal Hugoniots. To validate these simulations, we have performed shock compression experiments using the Sandia Z-Machine. A bond tracking analysis correlates the sharp rise in the Hugoniot curve with the completion of dissociation in ethane. The DFT-based simulation results compare well with the experimental data along the principal Hugoniots and are used to provide insight into the dissociation and temperature along the Hugoniots as a function of mixture composition.

description: But de l’étude : Nous avons procédé à une étude exploratoire en médecine légale, afin de comprendre et d’analyser le vécu des TRM dans ce milieu. Dans le contexte de la médecine légale, les corps pris en charge peuvent être altérés, putréfiés ou encore colonisés par des larves. Actuellement, le Centre Universitaire Romand de Médecine Légale (CURML) engage des techniciens en radiologie médical (TRM) pour effectuer les examens de radiologie post mortem. Ce nouveau poste implique un travail sur le corps encore inédit chez les TRM. Par exemple, ils effectuent des incisions de plusieurs centimètres au niveau du pli inguinal. Nous avons donc essayé de comprendre l’impact de cette prise en charge sur le vécu du TRM en médecine légale. Méthodologie : Nous avons mené une étude qualitative portée sur les observations et les entretiens de deux TRM du CURML. Nous avons estimé nécessaire de suivre au minimum ces deux TRM, afin de pouvoir constater l’aspect qualitatif lors de la confrontation avec le corps. Résultat : En suivant les TRM nous avons pu identifier plusieurs points importants. Le rôle du TRM en médecine légale, rôle que nous avons divisé en deux sous catégories, l’aspect lié à l’imagerie et le travail sur le corps, le ressenti du TRM, les stratégies et le respect du corps. Conclusion : Notre travail a démontré que le vécu de la prise en charge comporte des éléments différents, notamment les ressentis éprouvés ne sont pas toujours identiques chez les TRM, ce qui apporte des nuances dans les stratégies qu’ils emploient. Malgré les aspects liés aux ressentis, les TRM montrent beaucoup d’intérêt à la pratique de l’imagerie forensique et au développement de ce champs d’activité en général.

description: The evaluation of clustering results is difficult, highly dependent on the evaluated data set and the perspective of the beholder. There are many different clustering quality measures, which try to provide a general measure to validate clustering results. A very popular measure is the Silhouette. We discuss the efficient medoid-based variant of the Silhouette, perform a theoretical analysis of its properties, and provide two fast versions for the direct optimization. We combine ideas from the original Silhouette with the well-known PAM algorithm and its latest improvements FasterPAM. One of the versions guarantees equal results to the original variant and provides a run speedup of $O(k^2)$. In experiments on real data with 30000 samples and $k$=100, we observed a 10464$\times$ speedup compared to the original PAMMEDSIL algorithm.

description: The intercalation of Eu underneath Gr on Ir(111) is comprehensively investigated by microscopic, magnetic, and spectroscopic measurements, as well as by density functional theory. Depending on the coverage, the intercalated Eu atoms form either a $(2 \times 2)$ or a $(\sqrt{3} \times \sqrt{3})$R$30^{\circ}$ superstructure with respect to Gr. We investigate the mechanisms of Eu penetration through a nominally closed Gr sheet and measure the electronic structures and magnetic properties of the two intercalation systems. Their electronic structures are rather similar. Compared to Gr on Ir(111), the Gr bands in both systems are essentially rigidly shifted to larger binding energies resulting in n-doping. The hybridization of the Ir surface state $S_1$ with Gr states is lifted, and the moire superperiodic potential is strongly reduced. In contrast, the magnetic behavior of the two intercalation systems differs substantially as found by X-ray magnetic circular dichroism. The $(2 \times 2)$ Eu structure displays plain paramagnetic behavior, whereas for the $(\sqrt{3} \times \sqrt{3})$R$30^{\circ}$ structure the large zero-field susceptibility indicates ferromagnetic coupling, despite the absence of hysteresis at 10 K. For the latter structure, a considerable easy-plane magnetic anisotropy is observed and interpreted as shape anisotropy.

Coexistence of directed momentum current and ballistic energy diffusion in coupled non-Hermitian kicked rotors

description: We numerically investigate the quantum transport in a coupled kicked rotors with the $\mathcal{PT}$-symmetric potential. We find that the spontaneous $\mathcal{PT}$-symmetry breaking of wavefunctions emerges when the amplitude of the imaginary part of the complex potential is beyond a threshold value, which can be modulated by the coupling strength effectively. In the regime of the $\mathcal{PT}$-symmetry breaking, the particles driven by the periodical kicks move unidirectionally in momentum space, indicating the emergence of a directed current. Meanwhile, with increasing the coupling strength, we find a transition from the ballistic energy diffusion to a kind of the modified ballistic energy diffusion where the width of the wavepacket also increases with time in a power law. Our findings suggest that the decoherence effect induced by the interplay between the inter-particle coupling and the non-Hermitian driving potential is responsible for these particular transport behaviors.

description: Cette recherche a pour but d’explorer, selon une méthode qualitative et à partir d'entretiens semi-structurés, le lien qui peut exister entre un accompagnement infirmier de qualité et une gestion du deuil qui soit adaptée. Les besoins des conjoints ainsi que les pratiques infirmières sont étudiées, dans un contexte de soins palliatifs. L’intention est d’identifier les éléments de l’accompagnement qui préviennent les maladies somatiques ou psychologiques chez les conjoints. En quoi l’accompagnement infirmier, offert au conjoint d’une personne hospitalisée en soins palliatifs, peut avoir un impact sur sa santé, suite au décès ? Trois concepts sont développés : le deuil, l’accompagnement et la promotion de la santé.

description: Le but de cette recherche est de faire ressortir les facteurs d’influence du comportement d’enfants âgés de onze à treize ans en lien avec les boissons sucrées, et la manière dont une infirmière scolaire peut les intégrer dans une action de promotion de la santé. Elle vise à améliorer, dans un premier temps, la qualité d’une intervention menée lors d’un stage en milieu scolaire sur le sujet des boissons sucrées, mais également la qualité des prestations de promotion de la santé offertes en milieu scolaire. L’intérêt de cette recherche réside pour les enfants dans le fait de leur offrir une prise en charge adaptée à leurs besoins et de les amener ainsi à se questionner sur leur propre santé dans le but qu’ils deviennent à leur rythme acteurs de leur santé. Sept entretiens semi-dirigés ont été menés auprès d’enfants. Ils ont été élaborés et analysés à l’aide de deux théories principales, tout d’abord sous l’angle de la psychologie de la santé et plus particulièrement avec un modèle de comportement de santé, puis sous l’angle de la psychologie sociale des groupes.

description: The existence of magnetostriction in bulk BiFeO3 is still a matter of investigation and it is also an issue to investigate the magnetostriction effect in nano BiFeO3. Present work demonstrates the existence of magnetostrictive strain in superparamagnetic BiFeO3 nanoparticles at room temperature and the magnetoelectric coupling properties in composite form with P(VDFTrFE). Despite few reports on the magnetostriction effect in bulk BiFeO3 evidenced by the indirect method, the direct method (strain gauge) was employed in this work to examine the magnetostriction of superparamagnetic BiFeO3. In addition, a high magnetoelectric coupling coefficient was observed by the lock-in technique for optimized BiFeO3_P(VDF-TrFE) nanocomposite film. These nanocomposite films also exhibit room-temperature multiferroic properties. These results provide aspects of material with immense potential for practical applications in spintronics and magneto-electronics applications. We report a magnetoelectric sensor using superparamagnetic BiFeO3_P(VDF-TrFE) nanocomposite film for detection of ac magnetic field.
