Evita Mirada. Modos de ver a Eva Perón.
Authors: Ares María Cristina 
Published: May 2023

Resumen
Las representaciones visuales y literarias de Eva Perón han provocado controversias y polémicas dentro y fuera del movimiento peronista, han sido fuente de interpretaciones críticas con ecos en la lectura histórica y política de su figura. Su figura ha sido asociada a la momia, la profecía, el enigma, la esfinge, la máquina, la autómata, al vestuario, el monumento, la santidad, el espectro y el espejo. Si algo tienen en común todas estas imágenes es el carácter de enigmáticas. El acertijo las contiene y es lo que hace que la vigencia y el interés en sus estetizaciones no decaiga. En las últimas décadas que el cuerpo ha devenido en objeto privilegiado de problematización para la filosofía, las ciencias sociales y las teorías del arte en general, el cuerpo de Eva Perón, se impone como categoría de análisis privilegiada por su significativa productividad simbólica frente a la manipulación macabra padecida por su cadáver según registros históricos. La literatura y las artes visuales han manifestado un gran interés por el cuerpo de Eva Perón, han estetizado su muerte y su paso a la inmortalidad, su agonía y su enfermedad, el ultraje padecido post mortem y el robo de su cadáver, la taxidermia encargada y su transmutación en momia, el ocultamiento de su cuerpo y su recuperación, la repatriación y su conversión en fetiche. Pero a partir de 1992 se registra la estetización de su ausencia o bien la evocación de un cuerpo omitido que transmuta en una multiplicación y proliferación a modo de espejamiento infinito. Esa privación inicial se presenta enlazada con el horror. Las figuraciones estetizan esa omisión del cuerpo para acallar el espanto, como si se tratara de un pacto de decoro, con el fin de sofocar el horror amenazante. Tal sujeción que pugna por expresarse y retorna, acaba estetizándose desde la coacción a la que es sometida, resultando más temible aunque paradójicamente fascinante. Como si se tratara de un movimiento pendular, la ausencia en la representación de su cuerpo hacia finales del siglo XX, se trastoca en su opuesto: una propagación incalculable de cuerpos de Eva. El corpus seleccionado ha sido acotado a las producciones visuales y literarias de 1992 a 2019 y son de origen argentino, se trata de un recorrido escópico en torno al enigma evitista según cuatro articulaciones: una mirada barroca, una velada, una museal y una plegada. Que en la época de la recuperación de la materialidad carnal, las figuraciones corporales de Eva Perón se diluyan o se ofrezcan escenarios de su ausencia y luego proliferen en espectrales imágenes recursivas o especulares es lo que este estudio se propone examinar.

Improved Design-Oriented Analytical Modelling of Switched Reluctance Machines Based on Fröhlich-Kennelly Equations
Authors: Rocca Roberto , De Donato Giulio , Bolognesi Paolo , Giulii Capponi Fabio 
Published: May 2023

<p>Early design stages of modern Switched Reluctance Machines (SRMs) are well-known for demanding the analysis of thousands of candidates. The need for reducing the computation time is, in turn, fostering the interest in design-oriented analytical approaches capable to maintain sufficient accuracy for SRMs featuring different geometries and rated operating conditions. To this end, this work proposes a novel design-oriented analytical model that predicts the flux linkage loci, i.e., a set of curves expressing the phase flux linkage as a function of both phase current and rotor position, from which the main performance are attained. The model comprises two main parts, each of them containing a novel scientific contribution: 1) a new interpolation technique for the flux loci based on second-order Fröhlich-Kennelly equations, and 2) an analytical model that caters for the flux linkage in partial overlap and saturated core conditions. Finally, the model is validated against Finite Element results of four SRMs, along with the experimental results of one of them, and its implementation in a design routine is discussed. </p>

Abstract
A puzzling variety of superorbital modulations has been discovered in several supergiant high mass X-ray binaries (sgHMXBs). To investigate the mechanisms driving these superorbital modulations, we have analyzed long-term Neil Gehrels Swift Observatory (Swift) Burst Alert Telescope (BAT) observations of three sgHMXBs: 4U 1909 + 07, IGR J16418–4532, and IGR J16479–4514, and constructed their dynamic power spectra and superorbital intensity profiles. These Swift BAT observations are complemented by pointed Swift X-ray Telescope (XRT) and Nuclear Spectroscopic Telescope Array (NuSTAR) observations performed near the predicted maximum and minimum phase of a single superorbital cycle for each of these sources. The BAT dynamic power spectra show changes in the strength of the superorbital modulation on timescales of years, with either the peak at the fundamental frequency and/or the second harmonic present at different times for all three sources. The pointed Swift XRT and NuSTAR observations show no significant differences between the pulse profiles and spectral parameters at the superorbital maximum and minimum phase. This is likely due to the fact the superorbital modulation had weakened significantly during the times when the NuSTAR observations were carried out for all three sources. The results from the Swift XRT, BAT, and NuSTAR analysis indicate the possible presence of multiple corotating interaction regions (CIRs) in the stellar winds of the supergiant stars, although a structured stellar wind from the supergiant star due to tidal oscillations cannot be ruled out.

Abstract
The Colors of the Outer Solar System Origins Survey (Col-OSSOS) has gathered a high-quality, near-simultaneous, and brightness-complete sample of (g − r) and (r − J) colors for 102 Kuiper Belt objects (KBOs) with (u − g) and (r − z) gathered for some. We present the current state of the survey and data analysis. Recognizing that the optical colors of most icy bodies broadly follow the reddening curve, we present a new projection of the optical−near-IR (NIR) colors, which rectifies the main nonlinear features in the optical−NIR along the ordinates. We find evidence for a bifurcation in the projected colors that presents itself as a diagonal empty region in the optical−NIR. A reanalysis of past color surveys reveals the same bifurcation. We interpret this as evidence for two separate surface classes: the BrightIR class spans the full range of optical colors and broadly follows the reddening curve, while the FaintIR objects are limited in optical color and are less bright in the NIR than the BrightIR objects. We present a two-class model. Objects in each class consist of a mix of separate blue and red materials and span a broad range in color. Spectra are modeled as linear optical and NIR spectra with different slopes that intersect at some transition wavelength. The underlying spectral properties of the two classes reproduce the main observed structures in the UV−optical−NIR color space (0.4 μm ≲ λ ≲ 1.4 μm), including the bifurcation observed in the Col-OSSOS and H/WTSOSS data sets, including the tendency for cold classical KBOs to have lower (r − z) colors than excited objects, and the well-known bimodal optical color distribution.

Published: May 2023

Introduction: In folk medicine, dried white flowers of Sambucus nigra L. are used to make infusions, decoctions, and juices.
Aim: The present article aims to study and compare the antioxidant activity of aqueous solutions of leaves and flowers of Sambucus nigra L obtained at different exposure times and assess the antibacterial activity of these solutions against Escherichia coli ATCC 8739, Salmonella NCTC 6017, Listeria monocytogenes NCTC 11994, and Staphylococcus aureus ATCC 25093.
Materials and methods: We studied the physicochemical properties of aqueous extracts of leaves (fresh) and flowers (fresh and dry) of Sambucus nigra L collected from the Rhodope region of Bulgaria. The samples from Sambucus nigra L were analyzed to determine their total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP). The diameters (in millimeters) of the growth inhibition zones of four pathogens were measured, and a comparative assessment of their antibacterial activity was made.
Results: The infusions of fresh blossoms and fresh leaves of Sambucus nigra L had the highest antioxidant activity at the total contact time of 30 minutes (82.7&nbsp;mmol TE/100&nbsp;ml) and 35 minutes (36.5&nbsp;mmol TE/100&nbsp;ml), respectively. The phenol-richest infusions were those made from dried flowers of Sambucus nigra L after a 30-minute contact time (86.7&nbsp;mg GAE/ml). Of the four pathogens we studied, we found that the extracts affected partially only the pathogenic bacteria of Salmonella.
Conclusions: The highest content of bioactive components was obtained from dried blossoms of Sambucus nigra L. for infusions with a total contact time of 30 minutes and for decoctions at a contact time of 45 minutes.

La phobie scolaire de l’adolescent s’accompagne d’une angoisse si massive que l’inhibition en résultant constitue un obstacle à l’accès à la vie fantasmatique du patient. La conduite souvent associée de claustration à domicile nous oriente vers le fantasme archaïque de Claustrum développé par D. Meltzer. Il s’agit d’une forme d’indentification projective intrusive qui contrarie le conflit œdipien en s’opposant au processus de différenciation. Nous déployons ces notions à travers un cas clinique.
Eliminate Costly Component Out Of Pocket Defect Condition during Microelectronic Component Packaging/Shipping/Handling
Authors: Rochford Rich , Blanchette Craig 
Published: May 2023

High value devices used in microwave modules and other microelectronic assemblies have become increasingly thin and susceptible to “Component Out Of Pocket” (COOP) conditions that can occur during packaging, shipping, and customer handling. This defect condition is especially problematic for automated assembly which strives to be touch-free and efficient with orderly device presentation. COOP is a major contributor to “Cost Of Poor Quality” (COPQ) within the business. A funded study into COOP conditions was conducted and a dozen root causes were identified. It was discovered that traditional “waffle packs” have mechanical issues related to flatness tolerances with respect to the waffle tray and lid. The addition of a standard clip further contributes to the issue, both of which are key root causes of the costly “Component Out Of Pocket” (COOP) condition. A novel Lid-Clip System (LCS2) was engineered to compensate for those mechanical issues, bringing robust captivation and preservation of devices in waffle tray pockets. Static dissipative material for lid and clip was selected to provide unparalleled ESD Class 000 protection for high value devices with the lowest voltage susceptibility thresholds.

Published: May 2023

The various kinds of the packaging technologies such as 2.nD, 2.5D, 3D are highly studied with the rapid development of miniaturization and high density of semiconductor packaging. This trend increases the importance of fine pitch interconnect. To achieve fine pitch interconnect, Cu-Cu direct bonding or hybrid bonding which has no solder in bonding layer is the promising technologies. There are some difficulties in the solderless bonding such as the control of bump uniformity, high accuracy CMP (Chemical Mechanical Polishing) process and so on. In particular, the exact surface shape control is the essential issue. To solve these problems, we are proposing Nano porous (NP) Cu materials for interconnect material. One of the technical challenges is the process for formation of NP Cu µ-bump structure. We are focusing on electroplating process for µ-bump formation. Firstly, we developed the plating chemicals for formation of NP Cu structure. We consider two types of plating chemicals for NP Cu formation, de-alloying and direct porous plating process. For de-alloying process, Cu-Zn alloy bumps were plated, and NP Cu bumps were obtained by de-alloying the Cu-Zn alloy. For direct porous plating process, NP Cu bumps were plated by using unique additives which can form NP structure directly. By using electroplated NP Cu, we studied its various properties, and carried out bonding tests. As the results, NP Cu structure shows unique properties such as electrical conductivity and the hardness, and we consider that these unique properties should widen the bonding process margin. We would like to present our recent research of NP Cu which is promising materials for advanced bonding technology.
FEA Assisted Optimization of Bump Shear Test Method for Assessment of Back-End-of-Line Mechanical Integrity

Published: May 2023

An enhanced Cu pillar bump shear test (BST) method has been developed to quantify wafer level back-end-of-line (BEOL) mechanical integrity and assess the risk of white bump failure. First, three different types of failure mode in the BST and the one that corresponds to the white bump failure in which delamination occurs at an ultra-low-k (ULK) dielectric layer, were identified by studying the load-displacement data together with focused ion beam (FIB) and scanning electron microscopy (SEM) analysis. To find the reason for different failure modes in BST and the effects of BST conditions, first, the difference in the stress modes between the bump shear test and the assembly solder reflow process was compared using finite element analysis (FEA) stress simulations. Then, parametric studies on the bump shear angle and the bump shear height were performed to find the optimal conditions at which the BST stress modes best mimic those of the solder reflow. Based on these studies, special high Cu pillar bump test samples were built in order to apply the optimal shear height and angle condition. The new optimal BST method has shown to significantly increase the probability of ULK delamination failure mode and was shown to be in good agreement with reflow hammer test results. Also, the method was used to verify the effect of metal density as well as process and design changes. Finally, a machine learning based correlation for quantifying the pure BEOL integrity regardless of the bump and far-BEOL dimensions was developed for application of the method to various products.
