Research Progress in Vitamin A and Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a highly heterogeneous neurodevelopmental disorder. Over the past few decades, many studies have investigated the effects of VA supplementation in ASD patients and the relationship between vitamin A (VA) levels and ASD. VA is an essential micronutrient that plays an important role in various systems and biological processes in the form of retinoic acid (RA). Recent studies have shown that serum VA concentration is negatively correlated with the severity of ASD. The lack of VA during pregnancy or early fetal development can affect brain development and lead to long-term or even permanent impairment in the learning process, memory formation, and cognitive function. In addition, VA deficiency has been reported to have a major impact on the gastrointestinal function of children with ASD, while VA supplementation has been shown to improve the symptoms of ASD to a certain extent. This paper provides a comprehensive review of the relationship between VA and ASD.

Today’s computing challenges: opportunities for computer hardware design

Due to the explosive increase of digital data creation, demand on advancement of computing capability is ever increasing. However, the legacy approaches that we have used for continuous improvement of three elements of computer (process, memory, and interconnect) have started facing their limits, and therefore are not as effective as they used to be and are also expected to reach the end in the near future. Evidently, it is a large challenge for computer hardware industry. However, at the same time it also provides great opportunities for the hardware design industry to develop novel technologies and to take leadership away from incumbents. This paper reviews the technical challenges that today’s computing systems are facing and introduces potential directions for continuous advancement of computing capability, and discusses where computer hardware designers find good opportunities to contribute.

Memory as Public Identity

This chapter places collective memory at the basis of a country’s identity and posits that memory returns from the international sphere to the domestic environment. In the course of this process, memory moves from being an official strategy to becoming part of the wider public identity. Memory’s impact thus transforms from a direct, active opportunity to an indirect, passive constraint for policymakers. Notably, as identity, collective memory is unexamined, and assumed to underwrite the mindset of a country’s public and its representatives. To illustrate this transformation, this chapter looks to the cases of West Germany and Austria in the second post-war decade. The ‘critical situation’ for analysis arrived in 1961 in the form of Nazi war criminal Adolf Eichmann’s trial in Jerusalem. The West German and Austrian reactions to the trial demonstrate that by the early 1960s these countries had come to view their role in World War II through the lens of a pre-existing national narrative in almost entirely unexamined ways.

Reconstruction as a Long-Term Process. Memory, Experiences and Cultural Heritage in the Irpinia Post-Earthquake (November 23, 1980)

Reconstruction after an earthquake is often seen as a material issue, which concerns “objects” such as houses, roofs, and streets. This point of view is supported by the mass media showing the work progress in the disaster areas, especially in conjunction with anniversaries. Rather, we should consider reconstruction as a complex social process in which cultural backgrounds, expectations, and ideas of the future come into play, without neglecting geological, historical, legislative, economic, and political factors. Combining oral history sources and archival records, the article shows the paths taken by two small towns among the most affected by the earthquake of 23rd November 1980 (Mw 6.9). These towns have made opposite reconstruction choices (in situ and ex novo) representing two classical and different ways in which human societies can face their past and think their own future. A careful analysis of these forty-year experiences, with a special focus on cultural heritage, provides useful indications for post-disaster reconstructions in which more attention to the process, and not just to the final product, should be paid.

CULTURALLY CONDITIONED VISUAL COMMUNICATION IN CREATIVE EXPRESSION

The human body and its consciousness interacts with a number of external and internal factors, including, among others, the surrounding environment, experienced emotions, those things seen, things that are possessed and touched, and affection that is experienced, all of which accumulates over time as personal experience. In the aforementioned process memory plays the most significant role and predetermines the extent to which an individual remembers (and perceives) their own experience, and how they identify and are conscious of their own self-esteem, etc. The aim of this research is to record an idea and its transformations by reference to its associations, implementation and interpretations. Thus, transformations require personal experience, memory, knowledge, verbal and nonverbal abilities, as well as psychical phenomena that occur during research through the interaction of the participants. In our research task we presented 5 squares in which fragments of abstract pictures were placed. The participants were asked to freely interpret the fragments and complete the pictures. The results allowed us to conclude that associations and the process(es) of interpretation are inconstant and independent of each other. Associations usually visualise views of our physical environment, whereas intellectual creations are most frequently found in interpretations.

Pengujian Aplikasi menggunakan metode Load Testing dengan Apache JMeter pada Sistem Informasi Pertanian

Load Testing adalah teknik performance testing yang mana respon sistem diukur dalam berbagai load condition. Penelitian ini membantu menentukan bagaimana software berperilaku ketika beberapa user mengakses software secara bersamaan. Pengujian menggunakan method Black Box Testing dan Gorilla Testing sebagai Test Case Sampling. Black Box Testing adalah Pengujian fungsional software tanpa mengetahui struktur internal program (no knowledge).Gorilla Testing adalah Teknik pengujian dimana modul program berulang kali diuji untuk memastikan bahwa modul tersebut berfungsi dengan benar dan tidak ada bug. Modul dapat diuji lebih dari seratus kali, dan dengan cara yang sama. Jadi, Gorilla Testing juga dikenal sebagai "Frustrating Testing". Tujuannya adalah untuk menguji robustness.Pada penelitian ini target pengujian aplikasi adalah Loading time tidak >3 second, process memory tidak >400MB, dan data dapat masuk kedalam fungsi. Hasil pengujian load testing menunjukkan dengan menggunakan Apache JMeter bahwa target pengujian loading time dan process memory sudah terpenuhi.

Gearbox Fault Prediction of Wind Turbine Based on Improved NEST Model

This paper studies a fault prediction method for wind turbine gearbox. It uses grey relation analysis to get modeling variables, and makes sample data getting good integrity and redundancy by similarity analysis. Thus it gets the reduced process memory matrix, and trains the improved nonlinear state estimation (NEST) model. When the gearbox fails, the model residual will exceed the threshold value, and the model will give an early warning. Combined with the actual operation data of a wind turbine, the effectiveness and accuracy of the improved model are verified.
