Authors: Kaur Ravinder , Randhawa Kudrat , Kaur Sanimardeep , Shri Richa 
Published: March 2020

AbstractBackgroundAn earlier study demonstrated significant antioxidant and anticholinesterase activities of hydromethanol extract (HME) ofAllium cepa. The aim of the study was to investigate the component responsible for these activities followed by anin vivostudy.MethodsIn vitroantioxidant and anticholinesterase activities of standardized ethylacetate fraction (EAF) of HME were assessed. Bioactivity-guided fractionation showed that, as compared with its subfractions, EAF had most significant activity in 2,2-diphenyl-1-picrylhydrazyl and Ellman assays. Thus, EAF was further examined using a streptozotocin (STZ)-induced model of Alzheimer’s disease in mice. STZ was injected intracerebroventricularly on days 1 and 3 (3 mg/kg) in mice. EAF was thereafter administered (42, 84, and 168 mg/kg b.w./day p.o.) from days 9 to 22. The Morris water maze test was used to evaluate learning and memory in mice. Acetylcholinesterase (AChE) activity and oxidative stress markers were assessed in the brain homogenates of mice. Additionally, histopathological studies were performed to observe effects in the brain at the cellular level. EAF was standardized based on quercetin and quercetin 4′-O-glucoside content using a validated thin layer chromatography densitometric method.ResultsSTZ produced significant (p < 0.05) memory impairment along with oxidative stress and a cholinergic deficit in mice. EAF treatment ameliorated STZ-induced behavioral deficits and biochemical alterations in mice in a significant and dose-dependent manner.ConclusionsOur results show that EAF is efficacious in improving memory and learning via AChE inhibition and antioxidant activity in the mice brain. Thus, AC could be explored further to find out a lead candidate for Alzheimer’s disease.
Mass Surveillance: A Private Affair?
Authors: Macnish Kevin 
Published: March 2020

Abstract
Mass surveillance is a more real threat now than at any time in history. Digital communications and automated systems allow for the collection and processing of private information at a scale never seen before. Many argue that mass surveillance entails a significant loss of privacy. Others dispute that there is a loss of privacy if the information is only encountered by automated systems.
This paper argues that automated mass surveillance does not involve a significant loss of privacy. Through providing a definition of informational privacy as a matter of actual access of private information by one who can understand the meaning of that information, it follows that automated systems which lack understanding cannot of themselves diminish privacy. This is not to say that mass surveillance is unproblematic, though: it is deeply problematic. It is just that privacy is not the most significant of these problems.

Abstract
High-index dielectric nanostructures have emerged as an appealing complement to plasmonic nanostructures, offering similar light management capabilities at the nanoscale but free from the inherent optical losses. Despite the great interest in these all-dielectric architectures, their fabrication still requires cumbersome fabrication techniques that limit their implementation in many applications. Hence, the great interest in alternative scalable procedures. Among those, the fabrication of silicon spheres is at the forefront, with several routes available in the literature. However, the exploitation of the Mie modes sustained by these silicon resonators is limited over large areas by polydispersity or a lack of long-range order. Here, we present an all-dielectric metamaterial fabricated with a low cost and highly scalable technique: a combination of soft imprinting nanolithography and chemical vapor deposition. The resulting all-dielectric metasurface is composed of an array of silicon hemispheres on top of a high refractive index dielectric substrate. This architecture allows the exploitation of high-quality Mie resonances at a large scale due to the high monodispersity of the hemispheres organized in a single crystal two-dimensional lattice. The optical response of the metasurface can be engineered by the design parameters of the nanoimprinted structure. We further demonstrate the potential of this platform to enhance light emission by coupling dye molecules to the sustained Mie resonances and measuring both an eight-fold amplified signal and a triple lifetime reduction.

Abstract
Graja, A, Kacem, M, Hammouda, O, Borji, R, Bouzid, MA, Souissi, N, and Rebai, H. Physical, biochemical, and neuromuscular responses to repeated sprint exercise in eumenorrheic female handball players: effect of menstrual cycle phases. J Strength Cond Res 36(8): 2268–2276, 2022—Very few studies have been interested in the relationship between ovarian hormones and physiological function in female athletes. The aim of this study was to assess the effect of menstrual phases (MP) on physical, neuromuscular, and biochemical responses after repeated sprint exercise (RSE) in female handball players. Ten eumenorrheic athletes (22.5 ± 1.5 years, 1.70 ± 0.04 m) participated in 3 study visits (follicular phase [FP], luteal phase [LP], and premenstrual phase [PMP]). During each MP, they performed 20 × 5-second cycle sprints interspersed with 25 seconds of rest. Maximal voluntary contraction (MVC) tests of the knee extensor muscles at 90° of knee flexion were performed before and after RSE. Peak force and electromyography (EMG) signals were measured during the MVC tests. Blood samples were collected before and 3 minutes after each session. The percentage of decrement in peak power output over the 20 × 5-second cycle test (i.e., fatigue index) calculated between sprints 1 and 20 decreased significantly during PMP (−43.3% ± 5.7%) but not in LP (−39.2% ± 7.7%) compared with FP (−32.44% ± 6.3%) (p < 0.05). Moreover, no significant difference was found between MP in all frequency components of EMG before RSE (p > 0.05). Maximal voluntary contraction, neuromuscular efficiency, and median frequency values of vastus lateralis and rectus femoris were significantly decreased in PMP compared with FP and LP (p < 0.05). Creatine kinase (CK) levels were significantly higher in PMP compared with FP and LP after RSE (p < 0.05). These findings suggest that RSE induces more peripheral fatigue associated with muscle damage in PMP. This might be attributable to hormonal variation across MP. Therefore, FP seems to be the right time for intense training to improve strength performance.

Kapal penangkap ikan di Indonesia sebagian besar menggunakan mesin diesel sebagai tenaga penggeraknya. Mesin diesel merupakan mesin mekanis dimana singgungan komponen tidak dapat dihindari, sehingga sistem pelumas mutlak diperlukan untuk mengurangi tingkat kerusakan komponen yang bersinggungan. Penurunan kemampuan sisteem pelumas berdampak pada kerusakan mesin. Tujuan penelitian ini untuk mengidentifikasi penyebab kerusakan sistem pelumas mesin diesel kapal penangkap ikan sehingga memudahkan untuk membuat keputusan dalam melakukan tindakan perawatan dan perbaikan sistem pelumas. Metode untuk mengidentifikasi tiap kegagalan yang mungkin terjadi menggunakan Preliminary Hazard Analysis (PHA) dan Fault Tree Analysis (FTA). PHA merupakan perangkat untuk mengidentifikasi potensi bahaya yang mengakibatkan kegagalan sistem, FTA merupakan perangkat untuk mengidentifikasi penyebab kegagalan sistem. FTA bekerja dengan menentukan kegagalan yang disebut sebagai “top event”, selanjutnya top event diidentifikasi hubungan faktor penyebab berbagai peristiwa kegagalan dengan pohon kesalahan yang menggunakan gerbang logika sederhana “and” dan “or”. Terbentuknya FTA dapat menentukan faktor penyebab kegagalan dengan minimal cut set. Berdasarkan hasil analisis, terdapat tiga penyebab utama mesin diesel mengalami kegagalan karena sistem pelumas adalah gagalnya komponen sistem pelumas yaitu Kebocoran internal, (Screen pelumas + alarm tekanan + manometer + petugas), dan (Pompa pelumas + alarm tekanan + manometer + petugas).

The Influence of Trauma-Informed Yoga (TIY) on Emotion Regulation and Skilled Awareness in Sexual Assault Survivors
Authors: Nicotera Nicole , Connolly Margaret Megan 
Published: March 2020

Abstract
This study examined a Trauma-Informed Yoga (TIY) intervention created specifically for sexual assault survivors and delivered in a community-based group setting. Much of the existing research on this type of intervention has been conducted in clinical trials as opposed to community-based venues. As sexual assault is a common type of trauma and results more commonly in posttraumatic stress disorder (PTSD), the current study aimed to shed light on the potential benefits of a trauma-sensitive yoga and mindfulness intervention for survivors of sexual assault in the natural setting of a community-based organization. The intervention was developed and implemented by licensed mental health providers and registered yoga teachers and modeled on the evidence-based work of the Trauma Center at the Justice Research Institute. The study employed a traditional quantitative one-sample, pre- and posttest design. Survey items were drawn from two existing measures: (1) Five Facet Mindfulness Questionnaire and (2) Difficulties in Emotion Regulation Scale. The majority of the sample (n = 37) identified as White (67.6%), followed by Latina (13.5%), African American (8.1%), multiracial (5.4%), and other (2.7%). The mean age of participants was 29 years (standard deviation 8 years, range 18–56 years). All participants identified as female. Findings demonstrated statistically significant changes in participants’ emotion regulation and skilled awareness, both of which have the potential to reduce PTSD symptomatology. The present discussion considers the results in light of previous research and presents study limitations.

Providing new products by innovative entrepreneurs in Europe
Authors: Velilla Jorge , Ortega Raquel 
Published: March 2020

This paper addresses the individual factors that determine the provision of new products by entrepreneurs in Europe. To that end, we use the GEM 2014 Adult Population Survey, for sixteen European Countries, focusing on the demographic, economic, and environmental characteristics of this specific group of entrepreneurs. Our results indicate that education, experience, entrepreneurial skills, and income levels are the primary determinants in offering a new product. We also show that, in the case of ‘baby’ business owners, only the fear of failure and knowing other entrepreneurs are significant factors, while for nascent entrepreneurs, age, education, family size, income, and the social consideration of entrepreneurship also show significant correlations with the probability of offering new products.

The 21 May 1960 Mw 8.1 Concepción Earthquake: A Deep Megathrust Foreshock That Started the 1960 Central-South Chilean Seismic Sequence
Authors: Ojeda Javier , Ruiz Sergio , del Campo Francisco , Carvajal Matías 
Published: March 2020

AbstractOne of the most notable seismic sequences in modern times was recorded in May 1960 along the southern Chilean subduction zone. The sequence started on 21 May with the Mw 8.1 Concepción earthquake; 33 hr later the Mw 9.5 Valdivia megathrust earthquake occurred, the largest ever recorded in the instrumental period. These events changed the geomorphology of the coast along more than 1000 km, generated extensive structural damage in the main cities of central-south Chile, and triggered a Trans-Pacific tsunami. Observed land-level changes due to both earthquakes were reported in 1970. These observations were ascribed to both events but have been used to study only the general source properties of the 22 May Valdivia mainshock. Here, we separate these data to constrain for the first time the slip distribution of the 21 May Concepción earthquake, applying a Bayesian approach that considers uncertainties in the data. Our results show that the Mw 8.1 Concepción earthquake ruptured a deep segment of the megathrust, concentrated in a compact zone below the Arauco peninsula between depths of 20 and 50 km. Tsunami generation from this deep source agrees well with the tsunami arrival times and small amplitudes recorded by tide gauges along the Chilean coast. Our study highlights the importance of the 21 May 1960 Concepción earthquake in the context of large historical Chilean earthquakes.

Abstract
The city of Kairouan, the capital of the Aghlabides Dynasty (A.D. 800–909), and its surrounding areas were affected by a damaging earthquake on 8 Rajab 245 Hijri (9 October 859). Contemporaneous accounts by local travelers to the Abassides Califat (A.D. 750–1258) and reported by the chroniclers and historians Al Baghdadi (1980) and Al Tabari (A.D. 838–923) (1967) describe the damage to the city and report that 13 villages experienced extensive destruction, leading to a large number of people homeless. In the city of Kairouan, the dome and other holy places of the Great Mosque (minbar and mihrab), houses, fortifications, and bridges all suffered severe damage. The aqueduct that supplied Kairouan with fresh water from the western mountains was badly damaged at a location about 20 km west of the city. New archaeoseismic field investigations of the aqueduct using laser scanning and radiocarbon dating characterize the damaged features. Recent field investigations in the region taking into account the construction types and the inferred damage distribution suggest a macroseismic intensity reaching IX–X Medvedev–Sponhauer–Karnik scale. The seismotectonic context suggests a seismic source along the major Sbiba east–west-trending transpressive fault that includes the Cherichira, Sfaia, and El Baten folding system near Kairouan. An active fault system affecting late Quaternary units made up of ∼30-kilometer-long thrust-related en echelon folds associated with the east–west-trending fault is identified and characterized as seismogenic at a location about 20 km west of Kairouan.
