Vibration-insensitive optical path length control transducer for ring laser gyroscope
Authors: Yu Xudong , Xie Yuanping , Xiong Zhenyu , Liu Chang
Published: June 2019

A ring laser gyroscope is an optical sensor based on the Sagnac effect. It has many outstanding advantages, such as a short start-up time, a high precision, a wide dynamic range and a stable scale factor. It is insensitive to accelerations and is in wide use in aircraft attitude control, north finding applications including navigation and space missions. The path length transducer in a ring laser gyroscope is required to stabilize the optical path of the laser beams in the cavity. The path length control transducer may tilt in complex environment, which will cause deformation of resonant optical path in resonant cavity and seriously influence the performance of ring laser gyroscope. Firstly, for the first time, finite element analysis software ANSYS was used to simulate and analyze the small deformation of ring laser gyroscope’s grooved mirror in three directions under typical random vibrational spectra, their value were 2.08[Formula: see text], 2.10[Formula: see text] and 1.30[Formula: see text] respectively, and the deformation in the diaphragm of resonant cavity was obtained by combining with matrix optical theory quantitatively. Secondly, the influence rule of different radius of curvature and isostructural parameters on the tilt of path length control transducer was sought through quantitative analysis. Finally, combining with the change law of axial displacement in literature [ 5 ], an evaluation criterion for optimization was given and the optimized parameters were listed for path length control transducer. The tilt was reduced to 0.33[Formula: see text] after optimization, which was about 21.4% of current structure. The axial displacement reached 3.89 um, which was 1.84 times of existing structure. The research in the paper could provide reference for the design of path length control transducer of ring laser gyroscope.

Advertisements are the fuel that runs many online services such as websites or mobile apps, but also adversaries started to abuse ads for financial gains. Nowadays, online advertising companies track users all over the web in order to create successful online ads campaigns specifically tailored for a target audience. A popular phenomenon on the Internet, so-called adware, abuses online advertisements by maliciously injecting or replacing ads on websites. As many consider ads to be quite privacy intrusive, much work has gone into studying the effects of online advertisements on users’ privacy. However, only little work has been done so far into analyzing the privacy implications of adware.

In this work, we shed light on the capabilities, mainly concerning tracking and personal data exfiltrating, of adware and potentially unwanted programs (PUPs), at scale. To this end, we capture the communication of adware/PUPs in the Firefox browser on the application level to circumvent lower-level encryption (e.g., TLS). Using this framework for capturing the network traffic, we dynamically analyze the communication of over 16,000 adware or potentially unwanted program samples. We find that around 37% of requests issued by the analyzed samples contain some kind of personal information. Furthermore, we identify the services used by adversaries and provide insights on the used tracking techniques.

Authors: Gupta Harsh V. , Lyons Kelly E. , Wachter Nathaniel , Pahwa Rajesh
Published: June 2019

Background:

Levodopa is the most efficacious medication in controlling the motor symptoms of Parkinson’s disease (PD). There continues to be a controversy as to whether levodopa remains effective after years of therapy.

Objective:

To assess the long-term effectiveness of levodopa in PD patients.

Methods:

The response to levodopa in PD patients undergoing a levodopa challenge for deep brain stimulation (DBS) surgery evaluation from June 1997 through March 2017 were evaluated. The patients were broken into four groups based on disease duration (Group I: 0– 5 years, Group II: 6– 10 years, Group III: 11– 15 years, and Group IV:≥16 years). Levodopa response was calculated based on the changes in Unified Parkinson’s Disease Rating Scale (UPDRS) motor and activities of daily living (ADL) scores in the medication ON and OFF states.

Results:

A total of 361 PD patients were included. The mean age in Group I was 59.4 years with a mean disease duration of 3.9 years ( n = 29), Group II was 61 years with a mean disease duration of 8.1 years ( n = 131), Group III was 64 years with a mean disease duration of 12.8 years ( n = 143), and IV was 66.5 years with a mean disease duration of 18.5 years ( n = 58). There was a significant improvement in UPDRS motor and ADL scores after the levodopa challenge for all groups.

Conclusions:

In a subgroup of PD patients who were evaluated for DBS surgery, there was a marked improvement in UPDRS motor and ADL scores which did not decrease with disease progression.

Teoza (pobožavanje) kao biblijska i povijesna doktrina
Authors: Medved Goran
Published: June 2019

Ovo je prvi od dva članka od ovoga autora, koji istražuju doktrinu teoze, ponekad također zvanu pobožavanje, deifikacija ili divinizacija. Drugi članak predstavlja teozu kao novozavjetnu i evanđeosku doktrinu. Prvi članak predstavlja teozu kao biblijsku i povijesnu doktrinu. Prvi dio ovog članka analizira glavne biblijske tekstove za doktrinu teoze; njihovo tumačenje i usvajanje za teozu. Drugi dio ovog članka pruža pregled povijesnog razvoja doktrine teoze, od početka kršćanske misli do modernog doba. Pokazuje da teoza nije bila ograničena na istočne teologe nego je također bila zastupljena na Zapadu kod određenih vodećih teologa i pokreta. Zbog njezine bibličnosti i povijesnosti, teozu treba smatrati ključnom povijesnom doktrinom Crkve.
Open Questions on Writing and the Use of Croatian Exonyms on MapS
Authors: Crljenko Ivana
Published: June 2019

Croatian exonyms are Croatian adapted names of foreign geographical features that differ from their original names (endonyms). The writing, use, and treatment of exonyms are not always unambiguous, unique, systematic, and consistent. Thus, authors and editors of maps and atlases frequently face the question of should they choose an exonym (and which one), an endonym, or both. They resolve them by entering various exonym forms, using both forms of names (exonyms and endonyms), or omitting exonyms even when they exist. This situation is a direct outcome of having multiple names and of the different use of exonyms. Double naming can be the result of the complex status of toponyms in multilingual areas and of a vague boundary between current and historical exonyms. Until recently, the problems of writing and the use of exonyms were usually simply stated and confirmed by scarce examples. The purpose of this article is to stress out the need to apply a systematic approach to exonym research methodology. The aim is to highlight the open questions on writing and the use of Croatian exonyms by analysing general and school world atlases published in the last forty years, and to confirm them with representative examples. As the analysis indicates, writing and the use of many exonyms in our world atlases is quite chaotic. This is a consequence of having unstandardized exonyms and overly general orthographic rules and toponymic guidelines for exonyms. All mentioned should be in the focus of a national interdisciplinary authority that would carry out the standardization of all Croatian geographical names as well as exonyms.
Accurate Estimation of Frequency-Dependent Losses in High Voltage Test Transformers for the Assessment of Electric Discharge Powers
Authors: Laroussi Kada , Flazi Samir
Published: June 2019

The work presented in this paper is related to the project GEMUDE (Genérateur Multifonction de Décharge Electrique) which aims to design a universal high-voltage generator for electrical discharge studies. To design this variable high voltage source that operates in the frequency range of 0 to 1 kHz, the assessment of transformer losses represents a crucial phase during the design process. These losses in the coils and iron core of the transformer are closely related to the frequency and nature of the materials used. This paper presents a comparative study of transformer losses using analytical methods and experimental calorimetry measurements. Steinmetz empirical formula is used to estimate magnetic core losses whereas coil losses are evaluated by solving Maxwell equations. The main goal is to control these losses to limit the internal temperature rise in the transformer through the implementation of an efficient cooling solution. The results obtained by the analytical method were satisfactory which confirm the feasibility of measuring the power absorbed by the various electrical discharge devices upstream of the high-voltage transformer. This is because it turns out that the power of the generator in charge is the total power of the electric discharge and the transformer losses. This method, termed Power Disparity Method (PDM). In this paper, it is an easy and reliable way as compared with high voltage measurement methods.

Atomic Afrofuturism and Amiri Baraka's Compulsive Futures
Authors: Bagdanov Kristin George
Published: June 2019

In 1984, the same year that scholars were gathering at Cornell University to theorise ‘Nuclear Criticism,’ Amiri Baraka was formulating his own version of nuclear futurity in Primitive World: An Anti-Nuclear Jazz Musical. Baraka's musical manifests and conceptualises atomic afrofuturism, a historically specific affirmation of black existence that was forged while facing nuclear apocalypse. Nuclear Criticism, which lost much of its exigency after the end of the Cold War, needs to evolve to account for the present nuclear era, as its focus on totalities leaves it ill-equipped for incorporating the disparate lived experiences of those who have already experienced the apocalypse and for whom nuclear apocalypse is a repetition or extension of white supremacy's agenda of extinction. This article offers a genealogy of atomic afrofuturism, examining how throughout the cold war period African American artists like Sun Ra, Langston Hughes and Amiri Baraka were exploring the post-apocalyptic conditions of black existence, including its conflicting temporalities and tenses, while much of America still believed the apocalypse was imminent, not immanent. And so it is Derrida's anti-apocalyptic missives together with Baraka's anti-nuclear musical that can offer the framework Nuclear Criticism so desperately desires for imagining the unimaginable.
Messianic Fiction in Antoine Volodine's Nuclear Catastrophe Novel Minor Angels
Authors: Ellis Susannah
Published: June 2019

In Specters of Marx, Derrida suggests that a non-revolutionary — ‘spectral’ — Marxism could alleviate a contemporary crisis in imagining the future in the late twentieth century. This ‘presentist’ crisis results from the collapse of Communism and the alleged triumph of neoliberal democracy, and leaves a dubious choice between neoliberal consensus and potential totalitarianism. This article outlines Derrida's call to a messianic wait for the singularity of an always-arriving future-to-come, and suggests that it provides an entry into the post-nuclear universe of Antoine Volodine's Minor Angels, where a non-linear plot centres on the ghost of a failed Marxist revolutionary and its return. Outlining how Minor Angels creates a spectral temporality which undercuts both aspirations to a ‘radiant future’ and a stagnant present, this article argues that, read alongside, Derrida and Volodine sketch out a democratic future to come that gestures towards an alternative to presentism.

Published: June 2019

Background:
Diabetes mellitus a chronic disorder, poses a major health problem today. In diabetes, there is a considerable alteration in the composition of saliva, these alterations can be analysed and possibly evaluated in early detection of diabetes.

Aim of the study:
The aim of this study is to determine and compare the serum and salivary glucose levels, salivary amylase and total salivary protein concentrations, and to determine if salivary analytes can be a biomarker in detection of diabetes.

Materials and methods:
The present study includes a total of 80 individuals, with 40 type 2 diabetics and 40 age matched healthy controls. Diabetic status was assessed by random blood glucose levels. Unstimulated saliva from groups I and II was collected from each participant and analysed for glucose, amylase and total protein levels. Serum and Salivary glucose estimation was performed using glucose-oxidase end point assay method, amylase by direct substrate kinetic enzymatic method and total protein by pyrogallol red dye method.

Results:
A significantly higher salivary glucose (5.823 ± 2.035 mg/dl), salivary amylase (370.3 ± 243 u/l) and lower total proteins (73.4 ± 26.3 mg/dl) were observed in type 2 diabetics compared to salivary glucose ((1.1 ± 0.4409 mg/dl)), salivary amylase (128.8± 54.93 u/l) and higher total proteins (92.46 ± 25.17 mg/dl) in controls.

Conclusion:
These results suggest that diabetes influences the composition of saliva and also suggests that salivary analytes can be used as a diagnostic tool in the early detection of diabetes.

Rational regulation of phosphorus (P) use in the soil–rhizosphere–plant system is challenging in the development of sustainable, intensive, and healthy agriculture. Rational maize (Zea mays L.) based intercropping with legumes/oilseed rape across six experimental sites from 2008 to 2017 proved advantageous over monoculture in terms of both maize biomass production and P uptake. The partial land equivalent ratio (PLER) for P uptake by intercropped maize averaged from 0.58 to 0.92, which was significantly higher than that for biomass production (0.51–0.78), indicating that the advantage of P acquisition by intercropped maize was superior to that of biomass accumulation. It was the excessive accumulation of P in intercropped maize compared to monoculture, especially higher P concentrations in grains that led to the superior P acquisition advantage and luxury absorption of P. P concentrations in maize grains were significantly increased from 1.89–2.91 mg kg−1 in monoculture to 2.09–3.65 mg kg−1, in intercropping, by 8.3%–25.5%. The plant internal P use efficiency of maize was significantly decreased from the initial 411.7–775.7 kg kg−1 in monoculture to 345.7–710.4 kg kg−1 in intercropping by 4.9%–16.0%, and 100 kg maize grain P quantities were significantly increased from 0.25–0.46 kg to 0.27–0.54 kg by 7.0%–17.4%. Rational fertilizer P input maximized maize yields and P use without decreasing the interspecific ecological advantages and harvest indexes of grain yields and P. These findings promoted better understanding of P allocation status within maize plants, and yield and P acquisition advantages through the exploitation of the biological potential of plants for the efficient utilization of P resources in diverse species combinations.
A Primitive Trait in Two Breeds of Equus Caballus Revealed by Comparative Anatomy of the Distal Limb

Published: June 2019

The 55-million-year history of equine phylogeny has been well-documented from the skeletal record; however, this is less true for the soft tissue structures that are now vestigial in modern horse. A recent study reported that two ligamentous structures resembling functional interosseous muscle II and IV were evident in Dutch Konik horses. The current study investigates this finding and compares it to members of the genus Equus to identify either a breed anomaly or functional primitive trait. Distal limbs (n = 574) were dissected from four species of Equus; E. caballus, E. asinus, E. przewalskii and E. quagga boehmi. E. caballus is represented by 18 breeds of horse, including the primitive Dutch Konik’. The interosseous muscle II and IV were evident in all four species, but only two breeds of E. caballus expressed this trait-the Dutch Konik and Bosnian Mountain Horse. These two breeds were the only close descendants of the extinct Equus ferus ferus (Tarpan) represented in this study. In conclusion, the interosseous muscle II and IV originated from the distal nodule of metacarpal II and IV, respectively, and inserted into the corresponding branches of interosseous muscle III proximal to the sesamoids. This suggests a functional role in medial and lateral joint stability and a primitive trait in modern equids.

Published: June 2019

This study aimed to determine effects of weaning ages on growth, rumen development, and carcass characteristics and meat quality of Hu lambs. Thirty male Hu lambs were randomly divided into two weaning age groups: Weaned at 30 (W30) or 45 (W45) d of age. Blood samples were collected on the day of weaning before lambs (n = 5) were slaughtered, and then rumen sample was collected immediately after they were slaughtered. The intake of all feeds increased with age (p < 0.05), but were not affected by weaning age (p > 0.05). Oxidative stress indicators and immune variables, the plasma biochemical parameters did not differ between the two different weaning ages (p > 0.05). The two weaning age groups also had similar (p > 0.05) concentration of ruminal total volatile fatty acid. The two weaning age groups did not differ in body weight, carcass characteristics, or meat quality (p > 0.05) at d 120. These results indicate that weaning half a month earlier than the typical weaning age does not significantly affect the growth, ruminal development, or carcass characteristics of Hu lambs, and they can be weaned at 30 d of age to improve production efficiency.

Sweet orange (Citrus sinensis) peel, one of the most underutilized biowaste, was in this study employed for the green synthesis of gold nanoparticles (AuNPs) as an alternative source of reductant and stabilizer. Spherical AuNPs with narrow size distribution (1.75 ± 0.86 nm) were obtained by controlling pH and adjusting sequence for the first time. ultraviolet-visible (UV-vis) spectrophotometer, transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS), dynamic light scattering (DLS) were applied to detect the characteristic surface plasmon resonance peak, morphological and aggregate characteristic, elementary composition and hydrodynamic diameter, respectively. The major functional groups in extract were tested by Fourier transform infrared(FT-IR) spectrophotometer to characterize the components which are responsible for the reduction and stabilization of AuNPs. The possible role of the components during the process of AuNPs synthesis is also discussed. The result of this study enriched the green source for ultra-small AuNPs synthesis, and will help to understand the mechanism of synthesis and stability of ultra-small AuNPs by fruit peels extract.
Transporting and Storing High-Level Nuclear Waste in the U.S.—Insights from a Mathematical Model

Published: June 2019

The nuclear industry in the United States of America has accumulated about 70,000 metric tons of high-level nuclear waste over the past decades; at present, this waste is temporarily stored close to the nuclear power plants. The industry and the Department of Energy are now facing two related challenges: (i) will a permanent geological repository, e.g., Yucca Mountain, become available in the future, and if yes, when?; (ii) should the high-level waste be transported to interim storage facilities in the meantime, which may be safer and more cost economic? This paper presents a mathematical transportation model that evaluates the economic challenges and costs associated with different scenarios regarding the opening of a long-term geological repository. The model results suggest that any further delay in opening a long-term storage increases cost and consolidated interim storage facilities should be built now. We show that Yucca Mountain’s capacity is insufficient and additional storage is necessary. A sensitivity analysis for the reprocessing of high-level waste finds this uneconomic in all cases. This paper thus emphasizes the urgency of dealing with the high-level nuclear waste and informs the debate between the nuclear industry and policymakers on the basis of objective data and quantitative analysis.

Published: June 2019

The Accelerated Particle Swarm Optimization (APSO) algorithm is an efficient and the easiest to implement variant of the famous Particle Swarm Optimization (PSO) algorithm. PSO and its variant APSO have been implemented on the famous Short-Term Hydrothermal Scheduling (STHTS) problem in recent research, and they have shown promising results. The APSO algorithm can be further modified to enhance its optimizing capability by deploying dynamic search space squeezing. This paper presents the implementation of the improved APSO algorithm that is based on dynamic search space squeezing, on the short-term hydrothermal scheduling problem. To give a quantitative comparison, a true statistical comparison based on comparing means is also presented to draw conclusions.

Published: June 2019

In tomography, the resolution of the reconstructed 3D volume is inherently limited by the pixel resolution of the detector and optical phenomena. Machine learning has demonstrated powerful capabilities for super-resolution in several imaging applications. Such methods typically rely on the availability of high-quality training data for a series of similar objects. In many applications of tomography, existing machine learning methods cannot be used because scanning such a series of similar objects is either impossible or infeasible. In this paper, we propose a novel technique for improving the resolution of tomographic volumes that is based on the assumption that the local structure is similar throughout the object. Therefore, our approach does not require a training set of similar objects. The technique combines a specially designed scanning procedure with a machine learning method for super-resolution imaging. We demonstrate the effectiveness of our approach using both simulated and experimental data. The results show that the proposed method is able to significantly improve resolution of tomographic reconstructions.

Laser plasma acceleration (LPA) capable of providing femtosecond and GeV electron beams in cm scale distances brings a high interest for different applications, such as free electron laser and future colliders. Nevertheless, LPA high divergence and energy spread require an initial strong focus to mitigate the chromatic effects. The reliability, in particular with the pointing fluctuations, sets a real challenge for the control of the dispersion along the electron beam transport. We examine here how the magnetic defects of the first strong quadrupoles, in particular, the skew terms, can affect the brightness of the transported electron beam, in the case of the COXINEL transport line, designed for manipulating the electron beam properties for a free electron laser application. We also show that the higher the initial beam divergence, the larger the degradation. Experimentally, after having implemented a beam pointing alignment compensation method enabling us to adjust the position and dispersion independently, we demonstrate that the presence of non-negligible skew quadrupolar components induces a transversal spread and tilt of the beam, leading to an emittance growth and brightness reduction. We are able to reproduce the measurements with beam transport simulations using the measured electron beam parameters.

This research work was carried out to determine the effects of water contamination on the fatty acid (FA) profile of periphyton, zoobenthos, two Chinese carps and a common carp (Hypophthalmichthys molitrix, Ctenopharygodon idella and Cyprinus carpio), captured from highly polluted (HP), less polluted (LP), and non-polluted (NP) sites of the Indus river. We found that the concentration of heavy metals in the river water from the polluted locations exceeded the permissible limits suggested by the World Health Organization (WHO) and the US Environmental Protection Agency (EPA). Fatty acid profiles in periphyton, zoobenthos, H. molitrix, C. idella, and C. carpio in the food web of river ecosystems with different pollution levels were assessed. Lauric acid and arachidic acids were not detected in the biomass of periphyton and zoobenthos from HP and LP sites compared to NP sites. Alpha-linolenic acid (ALA), eicosadienoic acid and docosapentaenoic acid were not recorded in the biomass samples of periphyton and zoobenthos in both HP and LP sites. Caprylic acid, lauric acid, and arachidic acid were not found in H. molitrix, C. idella, and C. carpio captured from HP. In this study, 6 and 9 omega series FAs were identified in the muscle samples of H. molitrix, C. idella and C. carpio captured from HP and LP sites compared to NP sites, respectively. Less polyunsaturated fatty acids were observed in the muscle samples of H. molitrix, C. idella, and C. carpio collected from HP than from LP. The heavy metals showed significant negative correlations with the total FAs in periphyton, zoobenthos, and fish samples.
