Resumen: A partir de mediados de los años 90, en el campo la prácticaartística, se multiplican las obras que hacen de la exploración de la intimidadun tema mayor donde lo más fútil de la existencia cotidiana se convierteen el material predilecto. Muchas críticas estigmatizan el narcisismo deuna sociedad despolitizada y sometida al imperativo de la transparencia.Tomando una dirección opuesta, este artículo trata de mostrar que algunosartistas, al expresar aspectos de sus vidas íntimas, alcanzan a definir unmundo común propicio para el despliegue de interrogaciones políticas ysociales. Abstract: Since the second half of 1990’s, within the artistic practice field,numerous are the works that make the exploration of intimacy a major themewhere the most futile in daily existence becomes the favorite material. Alot of critics stigmatize the narcissism of a depoliticized society, submittedto the imperative of transparency. Taking an opposite direction, this article tries to explain that some artists, while expressing aspects of their intimate lives, succeed in defining a common world convenient for the deployment of political and social interrogations.

Published: April 2020

Resumen: Aunque el número de mujeres que han publicado textos autobiográficosha sido escaso, en gran medida porque han preferido llevar ala autoficción los aspectos de su intimidad, algunas se decidieron a comunicarsus sentimientos y vivencias en determinadas circunstancias. Es elcaso de Marga Gil Roësset, la artista que se suicidó por el amor no correspondidoa Juan Ramón Jiménez. Indagar en las características de un yofemenino que toma la pluma para expresar su pasión amorosa en un diarioy en las peculiaridades de su escritura es el objetivo de este trabajo. Abstract: Although the number of autobiographical texts written bywomen is scarce, due to a great extent to their preference to express theirprivate aspects through self-fiction, some of them decided, under certain circumstances, to communicate their own experience and feelings. This is the case of Marga Gil Roësset, the artist who committed suicide as a response to her unrequited love for Juan Ramon Jimenez. The aim of this paper is to make insights into the main features of a feminine self that takes up the pen to express her affectionate passion in her diary, as well as to focus on the particular traits of her writing.
El anélido Rotularia spirulaea (Lamarck, 1818) (Polychaeta, Serpulidae) de las margas del Eoceno de la Cuenca de Pamplona (Navarra): microestructura, tafonomía y paleoecología

Published: April 2020

En este trabajo se reconoce la presencia de numerosos fósilesdel anélido serpúlido Rotularia spirulaea (Lamarck, 1818) en las formaciones Areniscas de Ardanatz y Margas de Ilundain del Eoceno (Bartoniense y (?) Priaboniense) de la Cuenca de Pamplona (Navarra). Se estudian las diferentes capas de la microestructura prismática calcítica de su tubo. El tubo está constituido por una capa externa (1) gruesa, compuesta por tres zonas en continuidad entre ellas y otra capa
interna (2), de una extrema delgadez y siempre delimitando el lumen. R. spirulaea muestra una notable plasticidad ecofenotípica. La morfología trocoespiral, trocoespiralplaniespiral o planiespiral de los ejemplares podría estar relacionada con las características del sustrato –sin cohesión, medianamente cohesionado o cohesionado, respectivamente–, que condicionarían la capacidad de soportar al organismo durante su ontogenia. La disposición del tubo de R. spirulaea
durante el estadio trocoespiral sería recostada. Superada esta etapa, podía pasar a una forma planiespiral, con la formación de una carena o quilla estabilizadora hasta adquirir, de forma gradual, una posición vertical dentro del sustrato fangoso. Es a partir de este estadio, cuando se formaría la parte desenrollada del tubo que, a modo de chimenea, sobresaldría parcialmente del sedimento. La cavidad del tubo (lumen) habitualmente está rellenada por sedimento y/o cementada por cristales de calcita con tres etapas reconocibles y con ejemplos de texturas geopetales, que vendrían a apoyar la idea de una posición de vida vertical en la madurez de los individuos
Intraspecific variation in the cochleae of harbour porpoises (Phocoena phocoena) and its implications for comparative studies across odontocetes

Published: April 2020

In morphological traits, variation within species is generally considered to be lower than variation among species, although this assumption is rarely tested. This is particularly important in fields like palaeontology, where it is common to use a single individual as representative of a species due to the rarity of fossils. Here, we investigated intraspecific variation in the cochleae of harbour porpoises (Phocoena phocoena). Interspecific variation of cochlear morphology is well characterised among odontocetes (toothed whales) because of the importance of the structure in echolocation, but generally these studies use only a single cochlea to represent each species. In this study we compare variation within the cochleae of 18 specimens of P. phocoena with variations in cochlear morphology across 51 other odontocete species. Using both 3D landmark and linear measurement data, we performed Generalised Procrustes and principal component analyses to quantify shape variation. We then quantified intraspecific variation in our sample of P. phocoena by estimating disparity and the coefficient of variation for our 3D and linear data respectively. Finally, to determine whether intraspecific variation may confound the results of studies of interspecific variation, we used multivariate and univariate analyses of variance to test whether variation within the specimens of P. phocoena was significantly lower than that across odontocetes. We found low levels of intraspecific variation in the cochleae of P. phocoena, and that cochlear shape within P. phocoena was significantly less variable than across odontocetes. Although future studies should attempt to use multiple cochleae for every species, our results suggest that using just one cochlea for each species should not strongly influence the conclusions of comparative studies if our results are consistent across Cetacea.

Authors: Guo Zhen , Han Jichang , Li Juan 
Published: April 2020

Bacteria play a vital role in biotransformation of soil organic carbon (SOC). However, mechanisms of bacterium and organic carbon mineralization remain unclear during improvement of sandy soil using soft rock additions. In this study, four treatments with differing ratios of soft rock to sand of 0:1 (CK), 1:5 (C1), 1:2 (C2) and 1:1 (C3) were selected for mineralization incubation and high-throughput sequencing. The results showed that SOC, total nitrogen (TN), available phosphorus (AP), nitrate nitrogen (NO${}_{3}^{-}$-N), and mass water content (WC) of sandy soil increased significantly after addition of soft rock (P < 0.05). Compared with the CK treatment, cumulative mineralization and potential mineralized organic carbon content of C1, C2 and C3 increased by 71.79%–183.86% and 71.08%–173.33%. The cumulative mineralization rates of organic carbon treated with C1 and C2 were lower, 16.96% and 17.78%, respectively (P > 0.05). The three dominant bacteria were Actinobacteria, Proteobacteria and Chloroflexi, among which Proteobacteria was negatively correlated with mineralization of organic carbon (P < 0.01). The mineralization rate constant (k) was positively correlated and negatively correlated with Cyanobacteria and Nitrospirae, respectively. Under C2 treatment, Proteobacteria and Nitrospirae had the largest increase, and Cyanobacteria had the largest decrease. Compared with other treatments, C2 treatment significantly increased bacterial diversity index, richness index and evenness index, and the richness index had a negative correlation with k value. In conclusion, when the ratio of soft rock to sand was 1:2, the k of SOC could be reduced. In addition, the retention time of SOC can be increased, and resulting carbon fixation was improved.

Published: April 2020

Inhibin A (INHA) a member of the transforming growth factor-β (TGF-β) family has been implicated in the negative feedback control mechanism of the pituitary follicle stimulating hormone (FSH). Inhibin has been reported to be associated with litter size, milk yield, fertility and reproductive traits in ruminants.
A total of ten amino acid sequences (four sheep and six goats) were downloaded from the National Centre for Biotechnology Information database (http://www.ncbi.nlm.nih.gov/snp). The amino acid sequence alignment was carried out using ClustalW algorithm of Molecular Evolutionary Genetic Analysis software version 6.0. The functional effects of eighteen (18) amino acid substitutions of INHA gene in each of sheep and goats were predicted computationally using Polyphen-2, PROVEAN and SIFT algorithms while INHA gene functions and interactions with associated genes were investigated using GeneMANIA. Variants that were consensually predicted to be deleterious by the three algorithms utilised were referred to as ‘Cmutant’ and ‘Dmutant’ in sheep and goats, respectively. The MutPred was further used to determine the tolerance degree for each amino acid substitution of both the ‘Cmutant’ and ‘Dmutant’.
GeneMANIA revealed 20 genes that co-localised, co-expressed with, play functionally similar role or has physical or genetic interaction with INHA gene. Out of the studied eighteen (18) amino acid substitutions; there was a consensus by SIFT, PROVEAN and PolyPhen-2 algorithms in the prediction of variants C99R, C264D, L237T and F14C as being deleterious in sheep and variants D77F, L190K, R223D, L240N, C322T and P326C in goats. In goats, MutPred revealed that variants R223D and D77F were not harmful while, L190K, R223D, L240N and P326C mutations were observed to be highly harmful. In sheep, the ‘Dmutants’ (C99R, C264D, F14C and L237T) were predicted to be highly harmful. The obtained findings would be useful in planning research aiming at exploring the association between INHA gene variants and economically important traits of small ruminants.

Published: April 2020

Introduction: Cerebral palsy (CP)is due to damage occurring to the developing brain. This damage can occur during pregnancy, delivery, the first month of life, or less commonly in early childhood. Cerebral palsy is one of the most common causes of physical disability in childhood. Rates of cerebral palsy appear to be similar in both the developing and developed world. The overall CP morbidity rate will automatically increase unless a substantially improved outcome in survivors can be achieved. Children with CP are predisposed to many complications including renal stones.
Aim of the Study: The aim of this study was detection of prevalence and risk factors of urolithiasis in children with cerebral palsy.
Subjects and Methods: This cross sectional case control study was conducted on forty children suffering from cerebral palsy who were attending the Pediatric Neurology Unit of Tanta University Hospital through the period from March 2018 to March 2019. Forty age and sex matched children were taken as a control group.
Inclusion Criteria: Children suffering from different types of cerebral palsy at any age.
Exclusion Criteria: Children whose parents refuse to participate in the study, children receiving drugs that can cause renal stones.
A- Hematological Investigations: Total serum calcium, serum uric acid, serum creatinine.
B- Urinary: Complete urine analysis, urine culture,and urinary chemistry.
C - Imaging Study: Plain X-ray of abdomen. Pelvic and renal ultrasonography.
Results: Renal stone were detected in 12.5% of children with CP. Urinary tract infection, immobilization, hypercalcemia, hypercalciuria and hyperuricemia were the risk factors detected in this study.
Conclusion:Children with CP are liable to develop renal stones more than normal children.
Effect of Topical Proparacaine 0.5% on Tropicamide- Induced Mydriasis
Authors: Singh Punit Kumar , Singh Ananya 
Published: April 2020

Purpose: The topical anesthetic proparacaine (0.5%) is recommended to enhance the rate and magnitude of pupillary dilatation if it is instilled before mydriatic tropicamide. However there is scarcity of data supporting this. Therefore we conducted a study to analyze if preinstillation of topical proparacaine (0.5%) can potentiate the mydriatic efficacy of 0.8% tropicamide.
Methods: The patients were divided into two groups for pupillary dilatation. The study group was given a drop 0.5% proparacaine before instilling one drop of tropicamide while the control group was given the tropicamide alone. The pupillary size was measured and recorded before the instillation of tropicamide at 0 min, 15 min, 30 min. The end point was taken as 6 mm pupillary size (clinically effective diameter).
Results: There was a statistically significant difference in rate of pupillary diameter between the control and the study group. The rate of pupillary dilatation at 15min and 30 min was statistically significantly different between the control and study group.
Conclusion: The study concluded that prior instillation of topical proparacaine produced a statistically significant difference in the rate of pupillary dilatation at 30 mins. Therefore, we suggest the use of a topical anesthetic before tropicamide induced mydriasis.

Authors: Paixão Marcus Vinicius Sandoval 
Published: April 2020

The objective of this study was to overcome dormancy and germination capacity in sapoti seed storage. The study was conducted at IFES Seed Laboratory from January to December 2015. The experimental design was completely randomized with four replications of 25 seeds, in a split plot. The plots were represented by combinations of treatments of seeds: seeds without treatment; seeds stored for 24 hours in a refrigerator (8-10 ºC); seeds immersed in ice water for 30 min (0 ºC) and seeds stored permanently in a refrigerator at a temperature between 8-10 ºC. The subplots comprised the following storage period of the seeds: 0; 30; 60; 90; 120, 180; 270 and 360 days, at room temperature between 20-26° C. After each storage period were evaluated germination (%), germination speed index and average germination time. Treatment with ice for 30 min. showed the best germination. Permanent storage in refrigerator (8-10° C) presented the best-preserved viability. Heat treatment with ice for 30 min and/or permanent storage in the refrigerator can be used to break dormancy of sapoti seeds.

AbstractPurposeTo develop and test a three‐dimensional (3D) deep learning model for predicting 3D voxel‐wise dose distributions for intensity‐modulated radiotherapy (IMRT).MethodsA total of 122 postoperative rectal cancer cases treated by IMRT were considered in the study, of which 100 cases were randomly selected as the training–validating set and the remaining as the testing set. A 3D deep learning model named 3D U‐Res‐Net_B was constructed to predict 3D dose distributions. Eight types of 3D matrices from CT images, contoured structures, and beam configurations were fed into the independent input channel, respectively, and the 3D matrix of dose distributions was taken as the output to train the 3D model. The obtained 3D model was used to predict new 3D dose distributions. The predicted accuracy was evaluated in two aspects: (a) The dice similarity coefficients (DSCs) of different isodose volumes, the average dose difference of all voxels within the body, and 3%/5 mm global gamma passing rates of organs at risks (OARs) and planned target volume (PTV) were used to address the spatial correspondence between predicted and clinical delivered 3D dose distributions; (b) The dosimetric index (DI) including homogeneity index, conformity index, V50, V45 for PTV and OARs between predicted and clinical truth were statistically analyzed with the paired‐samples t test. The model was also compared with 3D U‐Net and the same architecture model without beam configurations input (named as 3D U‐Res‐Net_O).ResultsThe 3D U‐Res‐Net_B model predicted 3D dose distributions accurately. For the 22 testing cases, the average prediction bias ranged from −1.94% to 1.58%, and the overall mean absolute errors (MAEs) was 3.92 ± 4.16%; there was no statistically significant difference for nearly all DIs. The model had a DSCs value above 0.9 for most isodose volumes, and global 3D gamma passing rates varying from 0.81 to 0.90 for PTV and OARs, clearly outperforming 3D U‐Res‐Net_O and being slightly superior to 3D U‐Net.ConclusionsThis study developed a more general deep learning model by considering beam configurations input and achieved an accurate 3D voxel‐wise dose prediction for rectal cancer treated by IMRT, a potentially easier clinical implementation for more comprehensive automatic planning.
Reduced Hessian based parameter selection and estimation with simultaneous collocation approach
Authors: Chen Weifeng , Biegler Lorenz T. 
Published: April 2020

AbstractParameter estimation is a critical step in the building of process models. Given the nonlinear structure and limited measurements, it is often difficult to correctly estimate all the parameters involved in the model. Linear dependence and low correlation among the parameters are the main problems to be handled in parameter estimation. The common approach is to estimate a subset of the parameters by fixing the others at reasonable values. However, it is a challenge to determine which parameters can be properly estimated. In this work, the ratio between standard deviation and estimated parameter value is introduced for evaluating the estimability. A Gauss‐Jordan elimination based approach is proposed for parameter estimability ranking. Combined with the proposed ranking approach and approximate ratio criterion, a reduced Hessian based approach is proposed for parameter selection and estimation under a simultaneous collocation framework. The proposed approach is at least as effective and more efficient than competing approaches based on multiple eigenvalue decompositions or orthogonalizations for larger problems. Three case studies with increasing complexity are presented to demonstrate the performance of the proposed approach.

AbstractCOVID‐19 is a systemic infection with a significant impact on the hematopoietic system and hemostasis. Lymphopenia may be considered as a cardinal laboratory finding, with prognostic potential. Neutrophil/lymphocyte ratio and peak platelet/lymphocyte ratio may also have prognostic value in determining severe cases. During the disease course, longitudinal evaluation of lymphocyte count dynamics and inflammatory indices, including LDH, CRP and IL‐6 may help to identify cases with dismal prognosis and prompt intervention in order to improve outcomes. Biomarkers, such high serum procalcitonin and ferritin have also emerged as poor prognostic factors. Furthermore, blood hypercoagulability is common among hospitalized COVID‐19 patients. Elevated D‐Dimer levels are consistently reported, whereas their gradual increase during disease course is particularly associated with disease worsening. Other coagulation abnormalities such as PT and aPTT prolongation, fibrin degradation products increase, with severe thrombocytopenia lead to life‐threatening disseminated intravascular coagulation (DIC), which necessitates continuous vigilance and prompt intervention. So, COVID‐19 infected patients, whether hospitalized or ambulatory, are at high risk for venous thromboembolism, and an early and prolonged pharmacological thromboprophylaxis with low molecular weight heparin is highly recommended. Last but not least, the need for assuring blood donations during the pandemic is also highlighted.
