Authors: Noah Akande Oluwatobi , Christiana Abikoye Oluwakemi , Anthonia Kayode Aderonke , Lamari Yema
Published: May 2020

The feature extraction stage remains a major component of every biometric recognition system. In most instances, the eventual accuracy of a recognition system is dependent on the features extracted from the biometric trait and the feature extraction technique adopted. The widely adopted technique employs features extracted from healthy retinal images in training retina recognition system. However, literature has shown that certain eye diseases such as diabetic retinopathy (DR), hypertensive retinopathy, glaucoma, and cataract could alter the recognition accuracy of the retina recognition system. This connotes that a robust retina recognition system should be designed to accommodate healthy and diseased retinal images. A framework with two different approaches for retina image recognition is presented in this study. The first approach employed structural features for healthy retinal image recognition while the second employed vascular and lesion-based features for DR retinal image recognition. Any input retinal image was first examined for the presence of DR symptoms before the appropriate feature extraction technique was adopted. Recognition rates of 100% and 97.23% were achieved for the healthy and DR retinal images, respectively, and a false acceptance rate of 0.0444 and a false rejection rate of 0.0133 were also achieved.

Authors: Hu Sheng , Song Shuanjun , Liu Wenhui
Published: May 2020

Considering the problem that the process quality state is difficult to analyze and monitor under manufacturing big data, this paper proposed a data cloud model similarity-based quality fluctuation monitoring method in data-driven production process. Firstly, the randomness of state fluctuation is characterized by entropy and hyperentropy features. Then, the cloud pool drive model between quality fluctuation monitoring parameters is built. On this basis, cloud model similarity degree from the perspective of maximum fluctuation border is defined and calculated to realize the process state analysis and monitoring. Finally, the experiment is conducted to verify the adaptability and performance of the cloud model similarity-based quality control approach, and the results indicate that the proposed approach is a feasible and acceptable method to solve the process fluctuation monitoring and quality stability analysis in the production process.
Sealant Delamination Detection of Structural Sealant Glazing Systems Based on Driving-Point Accelerance
Authors: Pan Danguang , Jiang Kun , Zhang Xichen , Huang Ying
Published: May 2020

The structural sealant glazing system is widely used in glass curtain wall worldwide. However, due to the aging of the sealants, cracking may form along the sides of the glass. If the panel of curtain wall arises, delamination may occur and induce failure or loss of the system. In order to detect the delamination of the sealant, in this paper, a new vibration-based damage identification method is proposed by using the difference between the predamage and postdamage driving-point accelerance (DA). This detection method would require only one acceleration sensor on a glass panel and a rubber hammer, which operates very conveniently. When the rubber hammer taps the glass panel near the acceleration sensor, the glass curtain wall panel would generate acceleration response which can be measured by the acceleration sensor. The measured acceleration responses will be used to calculate the DA and lead to a new delamination index, called relative accumulative difference of DA, which will give indications on the potential delamination of the sealant. In addition, the influence of the acceleration sensor installation position was analysed by the finite element method, and the optimal sensor location was determined to be at the intersection of the long-side quarter and the short-side quarter. Nine cases on various delamination severities were identified by the new method, as well as the natural frequency reduction and modal assurance criterion. The laboratory experiments showed that the relative accumulative difference of DA is extremely sensitive to sealant delamination. Even if delamination severity was only 6.39%, the relative accumulative difference of DA would be larger than 18%. As the delamination of the sealant progresses, the relative accumulative difference of DA increases, resulting in an effective detection method for sealant delamination of the structural sealant glazing system. The fundamental frequency reduction is suitable to identify relatively large delamination, and the modal assurance criterion of higher modes is also sensitive to sealant delamination.
Stator Current Vector Orientation-Based Backstepping Predictive Control of Torque Ripple Minimization for PMSM with consideration of Electrical Loss
Authors: Yu Yang , Cong Leyao , Tian Xia , Xie Renjie , Lu Jianbin
Published: May 2020

Existing research studies on torque ripple suppression mostly ignore the electrical loss of PMSM. However, the electrical loss will not only decrease the operating efficiency but also adversely influence the suppression of torque ripple. This paper attempts to construct a unified framework to suppress torque ripple with consideration of electrical loss. Firstly, a dynamic mathematical model of PMSM under current vector orientation is established with a combination of electrical loss. The constraints that can achieve the control of both torque ripple and electrical loss for PMSM are derived. Then, on the basis of the backstepping control principle, a closed-loop I/f integrative control method under stator current vector orientation is proposed. Meanwhile, this paper also proposes a speed estimation algorithm of PMSM based on the least-squares method to realize wide-range speed identification and an online prediction algorithm for control parameters of backstepping control to enhance the stability of the motor in operation. Both simulations and experiments have been performed to verify the effectiveness of the proposed control method, and the results indicate that torque ripple is suppressed effectively, operating efficiency is significantly improved, and all variables are regulated to track their reference signals correctly and rapidly.
Proton Pump Inhibitor-Induced Galactorrhea in a Kidney Transplant Recipient: A Friend or Foe?
Authors: Prikis Marios , MacDougall Julie , Narasimhadevara Nina
Published: May 2020

Over the last decades, proton pump inhibitors (PPIs) have been widely used as the mainstay for treatment and prevention of gastrointestinal side effects, gastroesophageal reflux, and peptic ulcer disease. However, their safety profile has come into question recently after reports relating them to several side effects as well as kidney disease. Omeprazole, one of the mainly used PPIs, is almost entirely metabolized by the liver but the resulting metabolites are renally excreted. These metabolites may inhibit cytochrome P450 2C19 (CYP2C19) and cytochrome P450 3A4 (CYP3A4) reversibly, but as recent evidence suggests, they may also be involved in causing kidney disease. In the setting of renal dysfunction, these metabolites will not be excreted from the body and will accumulate further causing kidney damage and inhibiting CYP enzymes to a greater extent. Abnormally high serum prolactin levels leading to galactorrhea may be the result of such an accumulation. To our knowledge, there have been only three previously reported cases of PPI-induced galactorrhea in the literature but none in a kidney transplant recipient. In patients with established kidney disease and reduced glomerular filtration rate like kidney transplant recipients, the use of PPIs should be thoroughly assessed. Reduced clearance of their metabolites may lead to progression of the kidney disease and lead to more unwanted side effects. We present a case of a female kidney transplant recipient with worsening allograft function who presented with sudden galactorrhea and hyperprolactinemia while on a high-dose omeprazole for gastroesophageal reflux disease.

Published: May 2020

In this paper, we study a class of the Kirchhoff-Schrödinger-Poisson system. By using the quantitative deformation lemma and degree theory, the existence result of the least energy sign-changing solution u0 is obtained. Meanwhile, the energy doubling property is proved, that is, we prove that the energy of any sign-changing solution is strictly larger than twice that of the least energy. Moreover, we also get the convergence properties of u0 as the parameters b↘0 and λ↘0.
Actuator Fault-Tolerant Control Applied to Three-Tank System
Authors: Amor Mondher , Ladhari Taoufik , Hadj Said Salim , M’Sahli Faouzi
Published: May 2020

This paper focuses on the application of an active fault-tolerant control (AFTC) to a real nonlinear system using analytic redundancy in case of actuator faults. This approach is composed of the fault detection, isolation, and estimation (FDIE) module and a control compensation module. A high-gain observer (HGO) is used for FDIE; a new control law is then reconstructed by the addition of the estimated actuator fault magnitude to the nominal control law. Experimental results highlight the performance of the proposed approach when it is applied to the hydrographic plant.

Introduction. Several studiesdemonstrated that the use of alternate-day corticosteroid therapy maintains control of autoimmune diseases due to the prolongation of their therapeutic effect beyond their metabolic effect, with a significant decrease in side effects in patients. For this reason, the current recommendation for the use of these medications is in a short cycle to avoid adverse effects when used frequently and for prolonged periods of time. Objectives. To learn variations in serum levels of autoantibodies in autoimmune diseases treated with steroids on alternate days, as well as whether there are differences in the response to them depending on the type of disease. Study Design. A descriptive, retrospective, and cross-sectional study was conducted in which serum autoantibody levels were compared at the time of diagnosis and three months after alternate-day corticosteroid therapy. Results. We included 106 patients from three autoimmune connective tissue diseases (systemic lupus erythematosus, Sjögren syndrome, and Hashimoto’s thyroiditis) and observed a statistically significant decrease in serum autoantibody levels both in patients with lupus and those with Hashimoto’s thyroiditis, regardless of the sex of the patients, as well as the type of steroids used. Conclusions. Treatment with alternate-day corticosteroids achieved a statistically significant decrease in serum autoantibody levels in patients with systemic lupus erythematosus and Hashimoto’s thyroiditis.
Entanglement Quantification of Correlated Photons Generated by Three-Level Laser with Parametric Amplifier and Coupled to a Two-Mode Vacuum Reservoir
Authors: Gashu Chimdessa , Mosisa Ebisa , Abebe Tamirat
Published: May 2020

In this paper, the detailed inseparability criteria of entanglement quantification of correlated two-mode light generated by a three-level laser with a coherently driven parametric amplifier and coupled to a two-mode vacuum reservoir is thoroughly analyzed. Using the master equation, we obtain the stochastic differential equation and the correlation properties of the noise forces associated with the normal ordering. Next, we study the squeezing and the photon entanglement by considering different inseparability criteria. The various criteria of entanglement used in this paper show that the light generated by the quantum optical system is entangled and the amount of entanglement is amplified by introducing the parametric amplifier into the laser cavity and manipulating the linear gain coefficient.

Published: May 2020

Purpose:

The cytokine IL22 promotes tumor progression in murine models of colorectal cancer. However, the clinical significance of IL22 in human colorectal cancer remains unclear. We sought to determine whether the IL22 pathway is associated with prognosis in human colorectal cancer, and to identify mechanisms by which IL22 can influence disease progression.

Experimental Design:

Transcriptomic data from stage II/III colon cancers in independent discovery (GSE39582 population-based cohort, N = 566) and verification (PETACC3 clinical trial, N = 752) datasets were used to investigate the association between IL22 receptor expression (encoded by the genes IL22RA1 and IL10RB), tumor mutation status, and clinical outcome using Cox proportional hazard models. Functional interactions between IL22 and mutant KRAS were elucidated using human colorectal cancer cell lines and primary tumor organoids.

Results:

Transcriptomic analysis revealed a poor-prognosis subset of tumors characterized by high expression of IL22RA1, the alpha subunit of the heterodimeric IL22 receptor, and KRAS mutation [relapse-free survival (RFS): HR = 2.93, P = 0.0006; overall survival (OS): HR = 2.45, P = 0.0023]. KRAS mutations showed a similar interaction with IL10RB and conferred the worst prognosis in tumors with high expression of both IL22RA1 and IL10RB (RFS: HR = 3.81, P = 0.0036; OS: HR = 3.90, P = 0.0050). Analysis of human colorectal cancer cell lines and primary tumor organoids, including an isogenic cell line pair that differed only in KRAS mutation status, showed that IL22 and mutant KRAS cooperatively enhance cancer cell proliferation, in part through augmentation of the Myc pathway.

Conclusions:

Interactions between KRAS and IL22 signaling may underlie a previously unrecognized subset of clinically aggressive colorectal cancer that could benefit from therapeutic modulation of the IL22 pathway.
Cross-Resistance Among Next-Generation Antiandrogen Drugs Through the AKR1C3/AR-V7 Axis in Advanced Prostate Cancer

Published: May 2020

The next-generation antiandrogen drugs, XTANDI (enzalutamide), ZYTIGA (abiraterone acetate), ERLEADA (apalutamide) and NUBEQA (darolutamide) extend survival times and improve quality of life in patients with advanced prostate cancer. Despite these advances, resistance occurs frequently and there is currently no definitive cure for castration-resistant prostate cancer. Our previous studies identified that similar mechanisms of resistance to enzalutamide or abiraterone occur following treatment and cross-resistance exists between these therapies in advanced prostate cancer. Here, we show that enzalutamide- and abiraterone-resistant prostate cancer cells are further cross-resistant to apalutamide and darolutamide. Mechanistically, we have determined that the AKR1C3/AR-V7 axis confers this cross-resistance. Knockdown of AR-V7 in enzalutamide-resistant cells resensitize cells to apalutamide and darolutamide treatment. Furthermore, targeting AKR1C3 resensitizes resistant cells to apalutamide and darolutamide treatment through AR-V7 inhibition. Chronic apalutamide treatment in C4-2B cells activates the steroid hormone biosynthesis pathway and increases AKR1C3 expression, which confers resistance to enzalutamide, abiraterone, and darolutamide. In conclusion, our results suggest that apalutamide and darolutamide share similar resistant mechanisms with enzalutamide and abiraterone. The AKR1C3/AR-V7 complex confers cross-resistance to second-generation androgen receptor–targeted therapies in advanced prostate cancer.

Published: May 2020

Background: A number of guidelines have been developed to improve standardization of the terminology and criteria for cytologic specimens obtained from the thyroid, pancreas, lung, and salivary glands. A major goal of these guidelines is to improve reproducibility and understanding of the reporting of diagnostic results among cytopathologists and between cytopathologists and clinicians. The International Academy of Cytology Yokohama System for Reporting Breast Fine-Needle Aspiration Biopsy Cytopathology (IAC YSRB) is the most recent of these guidelines. The value of this system is, in part, dependent upon interobserver reproducibility. Design: Ninety consecutive fine-needle aspiration biopsies (FNAB) of the breast, performed over a 6-year period, were independently evaluated by 4 board-certified pathologists blinded to the original diagnoses. The 5 diagnostic categories used were those of the IAC YSRB according to published criteria for these categories. Observed agreement and chance corrected agreement (Fliess κ) were calculated. Differences in κ values were evaluated using the T statistic of Gwent. Statistical calculations were performed using STATA v16.0 (STATA Corp., College Station, TX, USA). Results: Overall agreement between observers was good. Observed unweighted agreement was 69% and weighted agreement was 91%. The majority of diagnoses were concordant (68.6%). Conclusions: Interobserver agreement of 4 cytopathologists was good using the 5 categories of the IAC YRSB (69%). Agreement was greater among pathologists with more years of experience. The IAC YSRB system appears to provide greater agreement among viewers than guidelines for cytologic specimens obtained from some other body sites (salivary gland and lung). Most discrepancies were only by a single category, with only 22/113 (19%) differing by more than one category.

Introduction: Pancreatic surgery still carries a high morbidity and mortality even in specialized centers. The aim of this study was to evaluate the influence of patients’ body composition on postoperative complications and survival after pancreatic surgery. Methods: This was a retrospective study on patients undergoing pancreatic surgery between March 2012 and December 2017. Demographics, clinical data, and postoperative complications classified according to Clavien-Dindo were recorded. Body composition was assessed using routine diagnostic or staging computed tomography (CT). Multiple Cox proportional hazards models were adjusted. Results: Ninety patients were included, 55% were male, and the mean age was 68 ± 10.9 years. Of these 90, 92% had a total pancreatectomy or pancreaticoduodenectomy, 7% a distal pancreatectomy, and 1% a pancreaticoduodenectomy with multi-visceral resection; 84% had malignant disease. The incidence of major complications was 27.8% and the 90-day mortality was 8.8%. The ratio of visceral fat area/skeletal muscle area (VFA:SMA) was associated with an increased risk of complications (OR 2.24, 95% CI 1.14–4.87, p = 0.03) and 90-day survival (HR 2.13, 95% CI 1.13–4.01, p = 0.019). On simple analysis, shorter overall survival (OS) was observed in patients aged ≥70 years (p = 0.0009), with postoperative complications ≥IIIb (p = 0.01), an increased VFA:SMA (p = 0.007), and decreased muscle radiation attenuation (p = 1.6 × 10–5). In an OS model adjusted for age, disease malignancy, postoperative complications, and body composition parameters, muscle radiation attenuation remained significantly associated with survival (HR 0.94, 95% CI 0.90–0.98, p = 0.0016). A model which included only body composition variables had a discrimination ability (C-statistic 0.76) superior to a model which comprised conventional clinical variables (C-statistic 0.68). Conclusion: Body composition is a major determinant of postoperative complications and survival in pancreatic surgery patients.

Published: May 2020

Introduction: The incidence of augmented renal clearance (ARC) in the intensive care unit (ICU) is highly variable, and identification of these patients remains challenging. Objective: The objective of this study was to define the incidence of ARC in a cohort of critically ill adults, using serum Cr and cystatin C, and to identify factors associated with its development. Methods: This is a retrospective cohort study of critically ill patients without stage 2 or 3 acute kidney injury with both serum Cr and cystatin C available. The incidence of ARC was defined as a Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)Cr-cystatin C-estimated glomerular filtration rate >130 mL/min. A multivariable logistic regression model using a penalized Lasso method was fit to identify independent predictors of ARC. Results: Among the 368 patients included in the study, indication for ICU admission was nonoperative in 55% of patients, and 9% of patients were admitted for major trauma. The overall incidence of ARC was low at 4.1%. In a multivariable logistic regression model, Charlson comorbidity index, major trauma, intracerebral hemorrhage, age, and Sequential Organ Failure Assessment score were found to predict ARC. Conclusion: The incidence of ARC in this study was low, but prediction models identified several factors for early identification of patients with risk factors for or who develop ARC, particularly in a cohort with a low baseline risk of ARC. These factors could be used to help identify patients who may develop ARC.

Published: May 2020

The distal ulna has always been considered to be expendable and its removal has been advocated for a variety of post-traumatic degenerative and oncological conditions but recent studies showed that the distal radioulnar joint allows supination and protonation of the forearm and is important to one’s grip strength and lifting ability. Several prosthesis models have already been made to replace the mechanical functionality of the distal radioulnar joint. We present two cases of females aged 22 and 12 years, respectively, who presented with wrist pain and swelling without any history of trauma and with terminal degree limitation in wrist movements due to tenderness and swelling. Both of them did not have any distant metastasis upon radiographic staging. The skeletally mature patient underwent radical excision of the distal ulnar osteosarcoma and received a distal radioulnar joint replacement prosthesis (Scheker prosthesis). The other skeletally immature patient underwent radical excision of the involved distal ulnar osteosarcoma with stabilization of the residual ulnar stump using the extensor carpi ulnaris sling in a modified version of the Goldner and Hayes technique. Both of our patients were treated according to the protocols of our multidisciplinary clinic sarcoma team by starting with neoadjuvant chemotherapy, followed by surgery and adjuvant chemotherapy. Both registered an almost complete restoration of the normal wrist and hand function and were in complete remission for 26 and 24 months, respectively. Based on our literature review, these are some of the extremely rare cases in which the osteosarcoma affected an unusual site (the distal ulna where they underwent a rare type of reconstruction status following radical excision of a malignant tumor).

Published: May 2020

Answer selection is an important task in Community Question Answering (CQA). In recent years, attention-based neural networks have been extensively studied in various natural language processing problems, including question answering. This paper explores matchLSTM for answer selection in CQA. A lexical gap in CQA is more challenging as questions and answers typical contain multiple sentences, irrelevant information, and noisy expressions. In our investigation, word-by-word attention in the original model does not work well on social question-answer pairs. We propose integrating supervised attention into matchLSTM. Specifically, we leverage lexical-semantic from external to guide the learning of attention weights for question-answer pairs. The proposed model learns more meaningful attention that allows performing better than the basic model. Our performance is among the top on SemEval datasets.

Published: May 2020

Nowadays, cryptography especially hash functions require to move from classical paradigms to an original concept able to handle security issues and new hardware architecture challenges as in distributed systems. In fact, most of current hash functions apply the same design pattern that was proved vulnerable against security threats; hence the impact of a potential weakness can be costly. Thus, the solution begins with a deep analysis of divers attack strategies; this way can lead to finding a new approach that enables new innovative and reliable candidates as alternative hash functions. So to achieve this goal, in this article we introduce a new construction design that consists of a non-iterative behavior by combining a parallel block processing and a sequential xor addition process, in order to provide a secure design without changing the expected goal of a hash function, at the same time avoid the use of vulnerable structures.

Published: May 2020

This paper presents the slope stability for road embankment constructed on the soft ground treated with prefabricated vertical drains (PVDs). The slope stability was evaluated based on the factor of safety (FOS) through numerical analysis and modeled with an artificial neural network (ANN). The permeability ratio of the smear effect was verified based on a comparative analysis between field data and numerical simulation to develop the datasets used in ANN model training. A total of 75 datasets generated from numerical simulations were randomly selected into three groups for training, testing, and validation. The coefficient of determination (R2) and root mean square error (RMSE) were considered to evaluate the performance ANN model. It was found that the developed ANN model showed strong potential for predicting slope stability within the accepted range.

Published: May 2020

This paper proposes a method for distributed generation (DG) placement in distribution system for losses minimization and voltage profile improvement. An IEEE 33-bus radial distribution system is used as the test system for the placement of DG. To facilitate the sizing of DG capacity, a meta-heuristic algorithm known as Continuous Domain Ant Colony Optimization (ACOR) is implemented. The ACOR is a modified version of the traditional ACO which was developed specially for solving continuous domain optimization problem like sizing a set of variables. The objective of this paper is to determine the optimal size and location of DG for power loss minimization and voltage profile mitigation. Three case studies were conducted for the purpose of verification. It was observed that the proposed technique is able to give satisfactory results of real power loss and voltage profile at post-optimization condition. Experiment under various loadings of the test system further justifies the objective of the study.

Published: May 2020

Tomato is a red-colored edible fruit originated from the American continent. There are a lot of plant diseases associated with tomatoes such as leaf mold, late blight, and mosaic virus. Tomato is an important vegetable crop that contributes to the world economically. Despite tremendous efforts in plant management, viral diseases are notoriously difficult to control and eradicate completely. Thus, accurate and faster detection of plant diseases is needed to mitigate the problem at the early stage. A computer vision approach is proposed to identify the disease by capturing the leaf images and detect the possibility of the diseases. A deep learning classifier is utilized to make a robust decision that covers a wide variety of leaf appearances. Compact deep learning architecture, which is MobileNet V2 has been fine-tuned to detect three types of tomato diseases. The algorithm is tested on 4,671 images from PlantVillage dataset. The results show that MobileNet V2 is able to detect the disease up to more than 90% accuracy.

Authors: Odoi Evah Wangui , Nagle Nicholas , Zaretzki Russell , Jordan Melissa , DuClos Chris , Kintziger Kristina W.
Published: May 2020

Background

Identifying social determinants of myocardial infarction (
MI
) hospitalizations is crucial for reducing/eliminating health disparities. Therefore, our objectives were to identify sociodemographic determinants of
MI
hospitalization risks and to assess if the impacts of these determinants vary by geographic location in Florida.

Methods and Results

This is a retrospective ecologic study at the county level. We obtained data for principal and secondary
MI
hospitalizations for Florida residents for the 2005–2014 period and calculated age‐ and sex‐adjusted
MI
hospitalization risks. We used a multivariable negative binomial model to identify sociodemographic determinants of
MI
hospitalization risks and a geographically weighted negative binomial model to assess if the strength of associations vary by location. There were 645 935
MI
hospitalizations (median age, 72 years; 58.1%, men; 73.9%, white). Age‐ and sex‐adjusted risks ranged from 18.49 to 69.48 cases/10 000 persons, and they were significantly higher in counties with low education levels (risk ratio [
RR
]=1.033,
P
<0.0001) and high divorce rate (
RR
, 0.995;
P
=0.018). However, they were significantly lower in counties with high proportions of rural (
RR
, 0.996;
P
<0.0001), black (RR, 1.026;
P
=0.032), and uninsured populations (
RR
, 0.983;
P
=0.040). Associations of
MI
hospitalization risks with education level and uninsured rate varied geographically (
P
for non‐stationarity test=0.001 and 0.043, respectively), with strongest associations in southern Florida (
RR
for <high school education, 1.036–1.041;
RR
for uninsured rate, 0.971–0.976).

Conclusions

Black race, divorce, rural residence, low education level, and lack of health insurance were significant determinants of
MI
hospitalization risks, but associations with the latter 2 were stronger in southern Florida. Thus, interventions for addressing
MI
hospitalization risks need to prioritize these populations and allocate resources based on empirical evidence from global and local models for maximum efficiency and effectiveness.
How Proactive Interference during New Associative Learning Impacts General and Specific Memory in Young and Old
Authors: Corbett Brittany , Duarte Audrey
Published: May 2020

Some prior research has found that older adults are more susceptible to proactive interference than young adults. The current study investigated whether age-related deficits in pFC-mediated cognitive control processes that act to detect and resolve interference underlie increased susceptibility to proactive interference in an associative memory task. Young and older adults were scanned while tasked with remembering which associate (face or scene) objects were paired with most recently during study, under conditions of high, low, or no proactive interference. After scanning, participants' memory was tested for varying levels of episodic detail about the pairings (i.e., target category vs. specific target category vs. specific target associate). Young and older adults were similarly susceptible to proactive interference. Memory for both the general target category and the specific target associate worsened as the level of proactive interference increased, with no robust age differences. For both young and older adults, the left ventrolateral pFC, which has been indicated in controlled retrieval of goal-relevant conceptual representations, was sensitive to increasing levels of interference during encoding but was insensitive to associative memory accuracy. Consistent with the Compensation-Related Utilization of Neural Circuits Hypothesis model of cognitive aging, the ventromedial pFC, which is involved in the monitoring of internally generated information, was recruited more by older than young adults to support the successful retrieval of target–object pairs at lower levels of proactive interference. Collectively, these results suggest that some older adults are able to engage in the cognitive control processes necessary to resolve proactive interference to the same extent as young adults.
A (Still) Marginal Modernity, or The Artist as Stenographer
Authors: Troeller Jordan
Published: May 2020

This essay discusses some of the stakes involved in this issue's cluster of texts on women photographers of Weimar Germany. They are critical assessments by contemporary art historians that draw attention to the still unfinished feminist project of questioning disciplinary assumptions around gender, sexuality, labor, and technologies of reproduction. These essays accompany four new translations of articles written in the 1960s and ’70s by a participant of that historical moment, Lucia Moholy, whose early reflections on the historical avant-gardes anticipate its feminist critique.
Lucia Moholy's Idle Hands
Authors: Troeller Jordan
Published: May 2020

At the time that she was affiliated with the Bauhaus, Lucia Moholy took a series of photographs at the nearby feminist commune of Schwarze Erde (also known as Schwarzerden), which was founded in 1923 by the poet Marie Buchhold and the pedagogue Elisabeth Vogler (and counted among its members Tilla Winz and Ilse Hoeborn). These photographs focus our attention on androgynous hands engaged in prosaic domestic tasks, as well as on the bodies of women and children involved in the commune's radical pedagogy of renewed bodily movement. The centrality of these images in Schwarzerden's publicity materials, along with their subsequent service as models for future photographs (most notably by Ruth Hallensleben), stands in contrast to the lack of appreciation Moholy received for performing similarly domestic labor for her male peers at the Bauhaus, including, above all, her husband, László Moholy-Nagy. By tracing the various ways in which idleness unfolds as a pictorial equivalent of housework, I argue that these images amount to a critique of an avant-garde photographic discourse that privileged “originality” and “production” over “documentation” and “reproduction.” Reading the photographs against the intention of their maker, who herself dismissed their “artistic value,” I propose that in mounting a challenge to artistic authorship, such images render visible the gendered contradictions of New Vision photography.
‘ABD AL-QĀHIR AL-BA GHDĀDĪ (D. 429/1037) AND THE STUDY OF THE QUR’ĀN
Authors: Rippin Andrew
Published: May 2020

The major contribution of ‘Abd al-Qāhir al-Baghdādī (d. 429/1037) to the study of the Qur’ān is his littlestudied book on abrogation, al-nāsikh wa’l-mansūkh. This work needs to be understood within the overall context of al-Baghdadi’s scholarly career which was devoted to reformulating the scholastic disciplines by making fiqh central to theology and to tafsīr. While his efforts may ultimately have been unsuccessful, they do reflect the environment of 5th/11th century Nīshāpūr and al-Baghdādī’s concern to create a “catholic” community within which differences of opinion were acceptable within the definition of the Muslim community. However, rivalries between disciplines meant that efforts to create this cohesive community went in several different directions.
QUR’ĀN AND WORLD PEACE
Authors: Azimidokht Seyyed Hossein
Published: May 2020

The question that which of the accounts of a religion is close to arrange social correlations is of importance nowadays. Part of this importance is due to the fact that religion still has a great role in ordinary life of people and societies. Although the religion has been a main factor in many kinds of social conflicts and among religions, Islam is not the exception, the author believes that articulating a spiritual account of Islam and its sacred book, i.e. the Qur’ān can properly help approach a good way of life in which all human beings acknowledge their stance as human beings and, in this way, promote rationality and peace. The article, basing itself on the Qur’ān, proposes a model for a spiritual Muslim person who can live in consistency with other religious people and never breaches human rights because of the observance of rationality.
AL-QUR’ĀN AND DIALOGUE
Authors: Latif Mohd. Abdul Nasir Abd. , Yusoff Zulkifli Mohd
Published: May 2020

Dialogue is one of the most important issues in the world because it directly refers to man’s mind. However, the dialogue in the Qur’ān acquires man’s mind to develop faith in Allah. A dialogue process between Gabriel and Prophet Muhammad SAW was the turning point before the first revelation sent to him. In fact, the dialogue appears to be a fundamental tool in communication which it has own strength, and plays a significant role in developing faith and belief. This process, then, moves to the next level of view’s sharing and exchange in which it would achieve better and stronger belief. This paper conducted an analysis which it has proved the Qur’ān strongly emphasized the dialogue process. The result of this paper presented ten elements of the dialogue in the Qur’ān which are comprised of da’wah, conversation/ debate, reading, speech, advise, reminder, instruction, interview-listening and supplication.
Taking Psychoanalytic and Psychometric Perspectives toward a Binocular Vision of Religion
Authors: Keller Barbara
Published: May 2020

Current psychology of religion relies mostly on quantitative psychometric approaches for the description, explanation, or prediction of religious experience and behavior, risking narrow reifications of operational definitions and neglect of individual experience. Psychoanalytic concepts are rarely addressed, due to being seen as lacking a scientific foundation, such as hypothesis testing based on large samples. Psychoanalysts have been slow to discuss religion without suspicion of pathology. Recently, psychoanalysts have broadened their empirical work and a “narrative turn” is discernible in developmental and personality psychology, allowing the inclusion of subjective perspectives. Drawing on these developments a rapprochement of psychodynamic and psychometric approaches is suggested to gain more depth of vision. Examples are given for the areas of development, personality, and psychotherapy.

A new species of African Snake-Eyed Skink (Scincidae: Panaspis) from Ethiopia
Authors: COLSTON TIMOTHY J. , PYRON R. ALEXANDER , BAUER AARON M.
Published: May 2020

A recent molecular phylogenetic revision of the snake-eyed skinks (genus Panaspis Cope, 1868) uncovered extensive cryptic diversity, including several new species from throughout sub-Saharan Africa. Here, we describe one of these from Ethiopia as Panaspis annettesabinae sp. nov. This description is based on a previous molecular phylogeny and morphological, scalation, and coloration data collected from the type specimen. Phylogenetic analyses place the species alone in what we term the P. annettesabinae species group from Ethiopia. This group forms the sister lineage to a large southern African radiation and suggests a potential northern origin for much of the extant diversity of Panaspis. Many new taxa have recently been discovered in the genus and region, and there are several historical records of Panaspis from elsewhere in Ethiopia. Thus, we suggest that the range of this new species (known only from a single specimen at present) may be much larger, and that additional undescribed species may exist in northern sub-Saharan Africa.
A new species of Lobulia (Squamata: Scincidae) from Papua New Guinea
Authors: KRAUS FRED
Published: May 2020

I describe a new skink of the genus Lobulia from Mt. Simpson in southeasternmost New Guinea. This species differs from all other members of the genus in having only three pairs of enlarged chin shields and only the first pair in medial contact. It is most similar in scalation to L. elegans but is readily distinguished from that species by its color pattern, body size and shape, and numbers of lamellae. Morphological data on L. elegans have not been reported since the description of the holotype in 1897, so I provide a redescription of that species based on six specimens—including the holotype—of certain conspecificity and from within approximately 100 km of the type locality at Mt. Victoria. I also elevate Lygosoma elegantoides lobulus from synonymy with Lobulia elegans, from which it is readily distinguished on the basis of scalational and color-pattern features. The resurrected L. lobulus and the new species from Mt. Simpson represent the seventh and eighth recognized species of Lobulia, and the Mt. Simpson species is the fifth member of the Papuan herpetofauna that is apparently endemic to Mt. Simpson. Mt. Simpson appears to be a moderate center of local endemism within southeastern New Guinea.
