Résumé :

Il lavoro – che vuole essere un contributo agli studi su lingua italiana, televisione e divulgazione linguistica - si occupa del programma tematico sull’italiano Le parole per dirlo, in onda ogni domenica mattina su Rai 3 dal mese di ottobre 2020, condotto da Noemi Gherrero con la partecipazione dei linguisti Valeria Della Valle e Giuseppe Patota. Le parole per dirlo è al momento in tv l’unica trasmissione interamente dedicata alla lingua italiana, dato significativo tanto più in un contesto televisivo che dedica ai programmi linguistici uno spazio di gran lunga inferiore a quello occupato da altri generi della divulgazione scientifico-culturale. Il lavoro presenta il programma in seno alla programmazione linguistica Rai dagli esordi (metà degli anni ‘50 del ‘900) a oggi e a correlati fattori storico-culturali, sociolinguistici, comunicativi (fasi e caratteri del mezzo televisivo e sua evoluzione tecnologica; missione di servizio pubblico della Rai; la “lingua” come oggetto di informazione culturale), descrive struttura delle puntate e aspetti crossmediali, illustra le strategie della divulgazione e i temi linguistici privilegiati, anche con focus su puntate specifiche, riportate secondo gli usuali criteri di trascrizione del parlato televisivo. Osservazioni su lingua e tecniche divulgative si basano su un totale di 28 ore e 20 minuti di materiali audiovisivi. The essay deals with a thematic programme on the Italian language, Le parole per dirlo, broadcast every Sunday morning on Rai 3 since October 2020. The programme is presented by Noemi Gherrero with the participation of two linguists, prof. Valeria Della Valle and prof. Giuseppe Patota and it is currently the only TV programme entirely dedicated to the Italian language (a very significant fact in a television programming scenario in which programmes about the Italian language are given less space than other scientific and cultural outreach programmes). The work presents the programme within the Rai linguistic programming from its beginnings (mid 1950s) to the present day and takes into consideration historical-cultural, sociolinguistic and communicative factors (phases and characteristics of the television medium and its technological evolution; Rai's public service mission; "language" as an object of cultural information). It describes then the structure of the episodes and cross-media aspects, the strategies of dissemination and the discussed linguistic themes: the analysis focuses on specific episodes, reported according to the usual criteria of transcription of television speech. Observations on language and dissemination techniques are based on a total of 28 hours and 20 minutes of audiovisual materials.

Résumé :

It is widely accepted that micro- and nanoscale inhomogeneities govern the performance of many thin-film solar cell absorbers. These inhomogeneities yield material properties (e.g., composition, structure, and charge collection) that are challenging to correlate across length scales and measurement modalities. The challenge is compounded if a correlation is sought during device operation or in conditions that mimic aging under particular stressors (e.g., heat and electrical bias). Correlative approaches, particularly those based on synchrotron x-ray sources, are powerful since they can access several material properties in different modes (e.g., fluorescence, diffraction, and absorption) with minimal sample preparation. Small-scale laboratory x-ray instruments have begun to offer multi-modality but are typically limited by low x-ray photon flux, low spatial resolution, or specific sample sizes. To overcome these limitations, a characterization stage was developed to enable multi-scale, multi-modal operando measurements of industrially relevant photovoltaic devices. The stage offers compatibility across synchrotron x-ray facilities, enabling correlation between nanoscale x-ray fluorescence microscopy, microscale x-ray diffraction microscopy, and x-ray beam induced current microscopy, among others. The stage can accommodate device sizes up to 25 × 25 mm2, offering access to multiple regions of interest and increasing the statistical significance of correlated properties. The stage materials can sustain humid and non-oxidizing atmospheres, and temperature ranges encountered by photovoltaic devices in operational environments (e.g., from 25 to 100 °C). As a case study, we discuss the functionality of the stage by studying Se-alloyed CdTe photovoltaic devices aged in the stage between 25 and 100 °C.

Résumé :

Abstract: Introduction: E: I ratio and r-MSSD are known indicators of cardiac vagal activity. But their determinants are unclear. Objective: To evaluate the determinants of E: I ratio and r-MSSD in healthy subjects. Materials and Methods: 141 healthy subjects were studied. In them body mass index (BMI), Q-T interval, heart rate (HR), systolic, diastolic, pulse and mean arterial blood pressure (MABP) were measured. Age and sex of the subjects were noted. E: I ratio and r-MSSD was estimated from one minute lead II electrocardiogram in supine position. E: I ratio was recorded while breathing at 6 respiratory cycles per minute and r-MSSD was quantified during normal breathing. Data was analyzed by Pearson Correlation Coefficient and unpaired t test. p value less than 0.05 was considered significant. Results: There was positive correlation between E: I ratio and r-MSSD (p = 0.006). E: I ratio and r-MSSD were negatively correlating with age (p < 0.01). r-MSSD was negatively correlating with HR, systolic, diastolic, pulse and MABP (p = 0.0001, 0.01, 0.03, 0.04, 0.01 respectively). r-MSSD did not correlate with BMI and Q-T interval. E: I ratio did not correlate with blood pressure, BMI and Q-T interval. Mean E: I ratio and r-MSSD of males did not differ compared to females. Conclusion: E: I ratio and r-MSSD are correlated. Age is an influencing factor of E: I ratio and r-MSSD. Blood pressure and HR are the other determinants of r-MSSD but not of E: I ratio in healthy subjects.

Introduction: Diabetes mellitus is a common metabolic disorder that contributes a significant burden on the healthcare system. It is one of the major comorbidities associated with COVID-19 and affects its severity. Aim: To study the correlation between COVID-19 disease severity and its outcome in diabetes mellitus patients and to correlate HbA1C with COVID-19 disease severity, NEWS, Ct RT-PCR value and clinical outcome in COVID-19 diabetic patients. Settings and Design: This was a prospective cross-sectional observational study conducted in the Department of Medicine, Maulana Azad Medical College. Method and Material: The study included a total of 60 subjects 30 in the diabetic group and 30 in the non-diabetic group. NEWS was calculated on the day of admission. HbA1C was correlated with disease severity, NEWS, Ct RT-PCR value and clinical outcome of patients. The data gathered were processed by SPSS version 25. The correlation between HbA1C, disease severity, NEWS, and Ct RT-PCR value was determined using Pearson correlation coefficient. Results: Diabetic patients have more severe COVID-19 disease. NEWS at admission was higher in these patients. Higher HbA1C is associated with severe disease. HbA1C positively correlates with NEWS but negatively correlates with Ct RT-PCR value. Incidences of organ injury and inflammatory markers were higher in diabetic patients. Diabetes was associated with more complications and worse outcomes. Conclusions: Diabetic patients are more susceptible to the development of severe and worse outcomes in COVID.

Résumé :

SUMMARY The purpose of this study was 1) to compare the translucency of seven different types of composite materials and three different shade categories (dentin, enamel, and translucent) by determining the translucency parameter (TP) and light transmittance (%T) and 2) to evaluate the correlation between the results of the two evaluation methods. Three shades (dentin A3, enamel A3, and clear translucent) of seven composite materials (Beautifil II [BF], Denfil [DF], Empress Direct [ED], Estelite Sigma Quick [ES], Gradia Direct [GD], Premise [PR], and Tetric N-Ceram [TC]) from different manufacturers were screened in this study. Ten disk-shaped specimens (10 mm in diameter and 1 mm in thickness) were prepared for each material. For the TP measurements, the colors of each specimen were recorded according to the CIELAB color scale against white and black backgrounds with a colorimeter and used to calculate the TP value. For the %T measurements, the mean direct transmittance through the specimen in the range between 380 and 780 nm was recorded using a spectrometer and computer software. Two-way analysis of variance (ANOVA) tests were performed to compare the TP and %T for the composite materials and shade categories. One-way ANOVA and Tukey tests were used for the seven composite materials per shade category and the three shade categories per composite material. The correlation between the two evaluation methods was determined using the Pearson correlation coefficient. All statistical procedures were performed within a 95% confidence level. TP differed significantly by composite material within each shade category (p<0.05) and by shade category within each composite material (p<0.05). %T differed significantly by composite material within each shade category (p<0.05) and by shade categories within each composite material (p<0.05), except for BF and ES. For the two evaluation methods, TP and %T, were positively correlated (r=0.626, p<0.05). These methods showed strong correlation for each composite material except ES (r=0.763-0.992, p<0.05) and moderate correlation for each shade category (r=0.403-0.528, p<0.05).

Résumé :

L’avvento di tecniche economiche per produrre fogli di materiali con spessore mono-atomico, come il grafene [1], ha aperto la possibilità di progettare materiali nanostrutturati con proprietà chimico/fisiche pre-programmabili. I sistemi tecnologicamente rilevanti a base di materiali correlati al grafene (GRM) sono principalmente networks di microfogli bidimensionali distribuiti in modo casuale e altamente difettosi [2]. Sebbene il trasporto di carica sia stato ampiamente trattato per fogli bidimensionali isolati [3], uno studio esaustivo che correli le proprietà elettriche dei GRM networks con la complessità della struttura e della morfologia del materiale è ancora mancante in letteratura. Lo scopo di questo lavoro è indagare il trasporto di carica (CT) in film sottili di GRM, con un certo grado di disordine strutturale. In particolare, abbiamo studiato i meccanismi di CT che si verificano all'interfaccia tra due fogli – spesso i meccanismi d’interfaccia sono considerati un fattore limitante – così come il ruolo della complessità geometrica del network nella conducibilità elettrica complessiva delle strutture di microfogli. Abbiamo utilizzato fogli monoatomici di grafene ossido (GO) come materiale bidimensionale modello. Il GO consiste infatti in un reticolo di grafene conduttivo che include gruppo funzionali dell’ossigeno sia sul piano basale che ai bordi del foglio. I microfogli isolanti di GO vengono depositati su substrati di ossido di silicio e sono ridotti termicamente per ripristinare alcune delle proprietà del grafene, tra cui la conducibilità elettrica. Oltre al GO ridotto, abbiamo impiegato un GRM composto da fogli multistrato di grafene (parzialmente ossidato). Tale materiale è il GO esfoliato elettrochimicamente (eGO). Abbiamo quindi sfruttato diversi metodi di deposizione: i) spin-coating, ii) spray-coating e iii) filtrazione assistita da vuoto per fabbricare film sottili di fogli di GRM parzialmente impilati e con dimensioni laterali macroscopiche. Le proprietà chimiche e morfologiche dei film sono state caratterizzate attraverso misurazioni di spettroscopia fotoelettronica a raggi X (XPS), microscopia a forza atomica (AFM) e diffrazione di raggi X (XRD). I meccanismi di trasporto sono stati studiati invece con misure di resistività elettrica (ρ) in funzione della temperatura, da valori ambientali fino a 5 K. Possibili ambiguità sull'analisi quantitativa di ρ(T) sono state risolte utilizzando un metodo autoconsistente basato sull'energia di attivazione ridotta [5], ovvero la derivata logaritmica della resistività rispetto alla temperatura: W(T)=-(d ln⁡ρ)⁄(d ln⁡T ). Questa trasformazione matematica ha permesso di analizzare il dataset ρ(T) con funzioni lineari. Abbiamo correlato i parametri caratteristici di trasporto con il grado di ordine dei nostri campioni e chiarito il ruolo dell'impacchettamento verticale dei fogli, ovvero dell'interazione π-π tra cluster aromatici sovrapposti, nel CT del film. Abbiamo inoltre evidenziato le differenze di CT tra i film basati su GO ridotto e quelli su eGO. Il lavoro proposto pone le basi per lo sviluppo di nuovi modelli e protocolli riguardanti i meccanismi di CT in sistemi realistici di GRM, come inchiostri e compositi polimerici. [1] Ferrari, A.

The development of cheap techniques to produce large sheets of monoatomic thick materials, such as graphene [1], opened new avenues to design nanostructured materials with pre-programmed chemical and physical properties. Most of the technologically relevant graphene-related materials (GRMs) systems are networks composed of randomly distributed and highly defective 2D microsheets [2]. While the charge transport has been extensively studied in single nanosheets [3], a comprehensive study that correlates the electrical properties of networks composed of purely 2D graphene-based materials with the complexity of the material structure and morphology is still missing. The aim of this work is to investigate charge transport (CT) in GRMs films, going towards structures with increasing disorder. In particular we investigated the CT mechanisms occurring at the sheet-to-sheet interface – typically the interfacial mechanisms are considered as bottlenecks – as well as the role of the geometrical complexity of the network in the overall electrical conductivity of the nanosheets assemblies. As prototypical 2D material we used single monolayer sheets of graphene oxide (GO), which consists of a conductive graphene lattice including oxygen functionalities/ defects both on the basal plane and at the edges of the sheet. Electrical insulating GO sheets are deposited on silicon oxide substrates and thermally reduced restoring partially the conductive properties of the 2D sheets. In addition to reduced GO, we employed a GRM made of multiple staked sheets of (partially oxidised) graphene bilayers: electrochemical exfoliated GO (eGO) [4].We exploited different deposition methods: i) spin-coating, ii) spray-coating and iii) vacuum-assisted filtration to fabricate macroscopic GRMs thin films with sheets partially stacked. Chemical and morphological properties of the films were characterized by X-ray Photoelectron Spectroscopy (XPS), Atomic Force Microscopy (AFM) and X-ray Diffraction (XRD) measurements. We investigated transport mechanisms measuring the temperature-dependence of the electrical resistivity (ρ) from room temperature down to 5 K. Possible ambiguities on the quantitative analysis of ρ(T) were solved by using a robust self-consistent method based on the reduced activation energy [5], i.e. the logarithmic derivative of resistivity versus temperature: W(T)=-(d ln⁡ρ)⁄(d ln⁡T ). This mathematical transformation allowed to analyse ρ(T) dataset with linear functions. We correlated the transport characteristic parameters with the degree of order of our samples and elucidate the role of the sheets vertical stacking, that is of the π-π interaction between overlapped aromatic clusters, in the CT in the film. We also highlighted the differences in CT between reduced GO based films and eGO ones. The presented work could pave the way to develop new models and protocols to access the CT mechanisms in realistic GRMs, such as inks and polymer composites. [1] Ferrari, A. C. et al.

Résumé :

La possibilità di controllare le proprietà elettroniche on-demand su una scala di tempo ultraveloce rappresenta una delle sfide più intriganti verso la realizzazione di dispositivi fotonici ed elettronici di nuova generazione. Stimolata da questo, negli ultimi decenni la ricerca scientifica ha concentrato la propria attenzione su diverse piattaforme a stato solido. Tra tutte, nanostrutture dielettriche (e metamateriali) e materiali correlati si presentano come i più promettenti candidati per la realizzazione di dispositivi dotati di nuove funzionalità. Al di là delle caratteristiche specifiche che rendono i dielettrici più adatti ad applicazioni in fotonica e i materiali correlati ai dispositivi elettronici, entrambe le categorie manifestano nuove funzionalità se soggetti ad uno stimolo esterno sotto forma di impulsi di luce con durata più breve della scala di tempo caratteristica del rilassamento dei gradi di libertà interni al sistema. Infatti, lo stato fuori equilibrio raggiunto a seguito di una foto-eccitazione presenta proprietà elettroniche ed ottiche di gran lunga differenti da quelle all'equilibrio. Pertanto, l'obiettivo di questo lavoro di tesi consiste nello sviluppo di nuovi metodi ed approcci sperimentali in grado di indurre, misurare e controllare nuove funzionalità in materiali complessi su una scala di tempo ultraveloce.
The possibility to control the electronic properties on-demand on an ultrafast time scale represents one of the most exciting challenges towards the realization of new generation photonic and electronic devices. Triggered by this, in the last decades the research activity focused its attention to different solid-state platforms. Among all, dielectric nanostructures (and metamaterials) and correlated materials represent the most promising candidate for the implementation of devices endowed by new functionalities. Apart from the specific features making dielectrics more suitable for photonic applications and correlated materials for electronic devices, both categories exhibit new functionalities if subjected to an external stimulus in the form of excitation light pulses shorter than the relaxation timescale of the internal degrees of freedom of the system. Indeed, the out-of-equilibrium state achieved upon photoexcitation exhibits electronic and optical properties highly different from those at equilibrium. Therefore, the aim of this thesis work consists in the development of new methods and experimental approaches capable to induce, measure, and control new functionalities in complex materials on an ultrafast time scale.

Résumé :

Electronic structure calculations constitute a valuable tool to predict the properties of materials. In this study we propose an efficient scheme to study correlated electron systems with essentially only one free parameter, the screening length of the Coulomb potential. A general reformulation of the exchange energy of the correlated electron shell is combined with this method in order to analyze the calculations. The results are interpreted in terms of different polarization channels, due to different multipoles. The method is applied to various actinide compounds, in order to increase the understanding of the complicate behaviour of 5f electrons in these systems. We studied the non-magnetic phase of δ-Pu, where the spin polarization is taken over by a spin-orbit-like term that does not break the time reversal symmetry. We also find that a non-trivial high multipole of the magnetization density, the triakontadipole, constitutes the ordering parameter in the mysterious hidden order phase of the heavy-fermion superconductor URu2Si2. This type of multipolar ordering is also found to play an essential role in the hexagonal-based superconductors UPd2Al3, UNi2Al3 and UPt3 and in the dioxide insulators UO2, NpO2 and PuO2. The triakontadipole moments are also present in all magnetic actinides we considered, except for Cm. These results led us to formulate a new set of rules for the ground state of a system, that are valid in presence of strong spin-orbit coupling interaction instead of those of Hund; the Katt's rules. Finally, we applied our method to a new class of high-Tc superconductors, the Fe-pnictides, where the Fe 3d electrons are moderately correlated. In these materials we obtain the stabilization of a low spin moment solution, in agreement with experiment, over a large moment solution, due to the gain in exchange energy in the formation of large multipoles of the spin magnetization density.

Résumé :

In this work we study the metal-insulator transition in vanadium dioxide and samarium nickelate and the application of such transitions in electronic devices. Chapter 1 provides an introduction to the Mott metal-insulator transition mechanisms and an overview of the interplay between various degrees of freedom in correlated oxides. The phase transition in vanadium dioxide is presented as an example to emphasize the overarching electron-phonon and electron-electron interaction driven transition mechanisms. In Chapter 2, we describe the growth and structure-functionality relationship of thin film transition metal oxides. Chapter 3 goes on to examine the mechanism of voltage-triggered metal-insulator transition in vanadium dioxide two-terminal threshold switches through dynamic studies. Chapter 4 delves into the mechanism of conductance modulation in electrolyte-gated vanadium dioxide transistors, which reveals the importance of electrochemical effects versus electrostatic effects in these devices. Utilizing the idea of electrochemical doping, we designed and realized a strongly correlated insulating phase in samarium nickel oxide through electron doping with hydrogen and lithium interstitials in Chapter 5. Such techniques can be extended to other materials to achieve reversible and controllable carrier doping with high concentration to study the related physics.

Résumé :

The eighteenth century saw the slow but steady rise of the middling classes to their nineteenth century social and cultural prominence, reinforced by a changing political landscape and the steadily increasing importance of the market. As the social and cultural power of the city burghers making up the majority of the middling classes grew, so did they start to consume in a manner to reflect to their new status in society. The question that arises then is more exactly how this group consumed, what types of objects that became important and what type of status that became the most paramount. Since status and social groups can differ greatly between both times and places, focus of this investigation is the burgher elite of Stockholm, the social, economical, and cultural centre of Sweden during the whole of the early modern era. By using a combination of Bourdieu's capital theories and Erving Goffman's theories on the presentation of self the inventories of fourteen elite burgher households has been analysed in order to investigate how these individuals constructed their home to present their own perceived social and cultural status. Through a thorough and theoretical investigation of these early modern front regions it can be revealed that the traditional representations of cultural capital, the main form of symbolic status capital, such as paintings and books, albeit important, constituted but a minor part of the capital presentation in the home. Instead it appears as if the most important status capital is presented through sociability, the ability to host social events or, if that option is unavailable, attend social events. Objects with the express function of sociability, such as tea- and dinner-ware, together with chairs, tables, and fashionable interior decoration suggests that sociability indeed stood at the forefront for the presentation of status for the late eighteenth century Stockholm burgher. At the same time, fashionability appears to have been extremely important, with almost all of the investigated households going to great lengths to stay up to date with the most recent trends in both furniture, colours, literature, and china. Much more research is however needed in order to really understand the structures of status and how it was expressed during the early modern times, and especially comparative studies between estate borders is needed in order to understand the status relations between social groups and how this affected status presentations.

Résumé :

Abstract After the discovery of topological insulators (TIs), it has come to be widely recognized that topological states of matter can actually be widespread. In this sense, TIs have established a new paradigm about topological materials. Recent years have seen a surge of interest in topological semimetals, which embody two different ways of generalizing the effectively massless electrons to bulk materials. Dirac and, particularly, Weyl semimetals should support several transport and optical phenomena that are still being sought in experiments. A number of promising experimental results indicate superconductivity in members of half-Hesuler semimetals which realize the mixing singlet and triplet pairing symmetry. We now turn to results we got through the work on topological semimetals. This work presents quantum high field transports on Dirac and Weyl topological semimetals including Sr1-yMn1-zSb2 (y, z < 0.1), YbMnBi2 and TaP. In case of Sr1-yMn1-zSb2 (y, z < 0.1), massless relativistic fermion was reported with m* = 0.04-0.05m0. This material presented a ferromagnetic order for in 304 K < T < 565 K, but a canted antiferromagnetic order with a net ferromagnetic component for T < 304 K. These are considered striking features of Dirac fermions For YbMnBi2, we reported the unusual interlayer quantum transport behavior in magnetoresistivity, resulting from the zeroth LL mode observed in this time reversal symmetry breaking type II Weyl semimetal. Also, for Weyl semimetal TaP the measurements probed multiple Fermi pockets, from which nontrivial π Berry phase and Zeeman splitting were extracted. Our ultra-low penetration depth measurements on half-Heuslers YPdBi and TbPdBi revealed a power- law behavior with n= 2.76 ± 0.04 for YPdBi samples and n=2.6 ± 0.3 for TbPdBi sample. We may conclude the exponent n > 2 implies nodless superconducting gap in our samples. Also, we found that despite the increase in magnetic correlations from YPdBi to TbPdBi, superconductivity remains robust in both systems which indicates that AF fluctuations do not play a major role in superconducting mechanism.

Résumé :

AbstractWe interact with different types of soft materials on a daily basis such as salt, hand cream, etc. Recently we have shown that soft materials can be described using four perceptual dimensions which are deformability, granularity, viscosity, and surface softness [1]. Here, we investigated whether humans can actually perceive systematic differences in materials that selectively vary along one of these four dimensions as well as how judgments on the different dimensions are correlated to softness judgments. We selected at least two material classes per dimension (e.g., hair gel and hand cream for viscosity) and varied the corresponding feature (e.g., the viscosity of hair gel). Participants ordered four to ten materials from each material class according to their corresponding main feature, and in addition, according to their softness. Rank orders of materials according to the main feature were consistent across participants and repetitions. Rank orders according to softness were correlated either positively or negatively with the judgments along the associated four perceptual dimensions. These findings support our notion of multiple softness dimensions and demonstrate that people can reliably discriminate materials which are artificially varied along each of these softness dimensions.

Résumé :

AbstractWe recorded vibratory patterns elicited by free haptic exploration of a large set of natural textures with a steel tool tip. Vision and audio signals during the exploration were excluded. After the exploration of each sample, participants provided judgments about its perceptual attributes and material category. We found that vibratory signals can be approximated by a single parameter in the temporal frequency domain, in a similar way as we can describe the spatial frequency spectrum of natural images. This parameter varies systematically between material categories and correlates with human perceptual judgements. It provides an estimate of the spectral composition of the power spectra which is highly correlated with the differential activity of the Rapidly Adapting (RA) and Pacinian Corpuscle (PC) afferents.

Résumé :

Photorefractive crystals are promising materials for real time correlation detection. However, the finite thickness of the crystal severely limits the size of the objects to be correlated and the shift invariance of the correlator due to Bragg diffraction. In this paper a beam compression technique in a joint transformation correlator is employed for reducing the writing angle. The technique greatly alleviates the Bragg diffraction limitation on the thickness of the crystal and increases the diffraction efficiency from the reading beam. On the other hand, the technique requires a proportional increase in the transverse size of the crystal to keep the correlation resolution constant.

Résumé :

One major limitation of photorefractive crystals is their relatively slow response time at reasonable light intensities [1]. In this paper we present a time integrating correlator using a photorefractive crystal which uses the slow response time of the crystal to its advantage. Specifically, we show that the response time is equivalent to the integration period of the correlator. An increase in the response time of the crystal will thus correspond to a longer integration time and consequently a larger processing gain for the system. Hence, inputs with very low signal to noise ratios can still be detected. In addition to the temporal aspect, the correlator uses the high recording bandwidth of the photorefractive effect to allow processing of signals of high time-bandwidth products, as well as to give the system the ability of presenting correlation outputs without bias. Experimental results for the photorefractive time integrating correlator are presented.
