Authors: Siregar Geminsah Putra H
Published: January 2022

Cyclamate is an artificial sweetener that is often added to drinks and food. In trade, cyclamate is known by the trade names assugrin, sucaryl, sucrose or sarimanis. The negative effects caused by sodium cyclamate are not immediate, it may have to wait two or thirty years later. The effects include increasing the potential for obesity, dental disorders, learning disorders, emotions, and mental health. testicular wasting and chromosomal damage. The purpose of this study was to determine the presence or absence of cyclamate content in cendol ice. The examination was carried out at the Amami Chemistry Laboratory, Health Polytechnic of the Ministry of Health, Medan, Department of Health Analyst using a qualitative test, namely the color test (deposition) with a total sample of 7 samples taken from cendol ice drink traders. Based on the qualitative test results obtained from 7 samples, 4 positive samples contained cyclamate. By knowing the presence of cyclamate content, it is hoped that producers will use food additives that do not have a negative effect on consumer health. Based on the Minister of Health Regulation No. 033/2012 artificial sweeteners are only intended for low-energy products or for people with diabetes mellitus and not for general let alone especially for children
nalysis of Impact of Alcohol on Brain's Activity
Authors:   , Tripathy Dharitri
Published: January 2022

Electroencephalography is an electrophysiological monitoring process to capture electrical activity on the scalp that has been shown to represent the macroscopic activity of the surface layer of the brain underneath. It is typically non-invasive, with the electrodes placed along the scalp. Computer programs in different programming language such as MATLAB, Python are used to simulate and study brain signals. This thesis focuses on utilizing Python, an open-source programming language to understand the impact of alcohol on one’s memory and attention and comparing them with non-alcoholic brain. To carry out this research, we are using open-source EEG data collected from alcoholic and non-alcoholic subjects subjected to visual stimuli. Experiments are carried out to observe spatial patterns related to both groups' brain activity and their association with different region of brain such as memory, attention, somatosensory, and emotional regulation regions. Besides the spatial pattern, we are also focusing to find source signals and their association with respect to attention region to understand the impact of alcohol on one’s attention function. Finally, the optimal sources based on optimal alpha and gamma rhythms are estimated. For these optimal source channels, we estimated time-frequency based spectrogram to understand the association of other band powers for both groups. Beta power activities from these spectrograms are analyzed for both groups to understand attention-deficit caused by alcohol consumption. By analyzing the results from the experiments can help us understand the impact of alcohol on one's brain's activity.
Automated Deep Neural Network Approach for Detection of Epileptic Seizures
Authors:   , Moazen Nadia
Published: January 2022

In this thesis, I focus on exploiting electroencephalography (EEG) signals for early seizure diagnosis in patients. This process is based on a powerful deep learning algorithm for times series data called Long Short-Term Memory (LSTM) network. Since manual and visual inspection (detection) of epileptic seizure through the electroencephalography (EEG) signal by expert neurologists is time-consuming, work-intensive and error-prone and it might take a couple hours for experts to analyze a single patient record and to do recognition when immediate action is needed to be taken. This thesis proposes a reliable automatic seizure/non-seizure classification method that could facilitate the identification process of characteristic epileptic patterns, such as pre-ictal spikes, seizures and determination of seizure frequency, seizure type, etc. In order to recognize epileptic seizure accurately, the proposed model exploits the temporal dependencies in the EEG data. Experiments on clinical data present that this method achieves a high seizure prediction accuracy and maintains reliable performance. This thesis also finds the most efficient lengths of EEG recording for highest accuracies of different classification in the automated seizure detection realm. It could help non-experts to predict the seizure more comprehensively and bring awareness to patients and caregivers of upcoming seizures, enhancing the daily lives of patients against unpredictable occurrence of seizures.
Research note: Fighting misinformation or fighting for information?
Authors: Acerbi Alberto , Altay Sacha , Mercier Hugo
Published: January 2022

A wealth of interventions have been devised to reduce belief in fake news or the tendency to share such news. By contrast, interventions aimed at increasing trust in reliable news sources have received less attention. In this article we show that, given the very limited prevalence of misinformation (including fake news), interventions aimed at reducing acceptance or spread of such news are bound to have very small effects on the overall quality of the information environment, especially compared to interventions aimed at increasing trust in reliable news sources. To make this argument, we simulate the effect that such interventions have on a global information score, which increases when people accept reliable information and decreases when people accept misinformation.
On the Power of Standard Information for Tractability for L2- Approximation in the Randomized Setting
Authors: Lu Wanting , Wang Heping
Published: January 2022

We study the approximation of multivariate functions from a separable Hilbert space in the randomized setting with the error measured in the weighted L2 norm. We consider algorithms that use standard information Λstd consisting of function values or general linear information Λall consisting of arbitrary linear functionals. We investigate the equivalences of various notions of algebraic and exponential tractability in the randomized setting for Λstd and Λall for the normalized or absolute error criterion. For the normalized error criterion, we show that the power of Λstd is the same as that of Λall for all notions of exponential tractability and some notions of algebraic tractability without any condition. For the absolute error criterion, we show that the power of Λstd is the same as that of Λall for all notions of algebraic and exponential tractability without any condition. Specifically, we solve Open Problems 98, 101, 102 and almost solve Open Problem 100 as posed by E.Novak and H.Wo´zniakowski in the book: Tractability of Multivariate Problems, Volume III: Standard Information for Operators, EMS Tracts in Mathematics, Zürich, 2012.

We evaluated the association of signal transducer and activator of transcription 3 (STAT3) polymorphisms with the incidence of mammalian target of rapamycin (mTOR) inhibitor-induced interstitial lung disease (ILD) in patients with renal cell carcinoma (RCC). We also used lung-derived
cell lines to investigate the mechanisms of this association. Japanese patients with metastatic RCC who were treated with mTOR inhibitors were genotyped for the STAT3 polymorphism, rs4796793 (1697C/G). We evaluated the association of the STAT3 genotype with the incidence of ILD
and therapeutic outcome. In the 57 patients included in the primary analysis, the ILD rate within 140 days was significantly higher in patients with the GG genotype compared with those with other genotypes (77.8% vs. 23.1%, odds ratio=11.67, 95% confidential interval=3.0644.46). There were
no significant differences in progression-free survival or time-to-treatment failure between the patients with the GG genotype and those with other genotypes. An in vitro study demonstrated that some lung-derived cell lines carrying the GG genotype exhibited an increase in the expression of
mesenchymal markers, such as fibronectin, N-cadherin, and vimentin, and decreases in E-cadherin, which is an epithelial marker associated with exposure to everolimus, although STAT3 expression and activity were not related to the genotype. In conclusion, the GG genotype of the STAT3
rs4796793 polymorphism increases the risk of mTOR inhibitor-induced ILD, supporting its use as a predictive marker for RCC.

Numerical Investigation on Flood Water Sloshing Influence on Intact and Damaged Stability of Ship
Authors: Mohan Poonam , Shashikala A. P.
Published: January 2022

Sloshing affects the intact and damage stability of the ship, which causes variation in dynamic metacentric height (GM) under critical load conditions. The transient flooding soon after the ship damage is analyzed, with floodwater accumulation in large space and causing the ship to suffer huge heel angles. The ship motion and stability changes when sloshing becomes high in partially flooded compartments. Most of the previous researches focus on the motion response of ship alone, hence the variation of stability due to sloshing is to be more critically studied. In the present study, three critical damage locations are identified and flooding through these locations are analyzed using the volume of fluids method. The method focus on finding damage ship motion response, flood water dynamics, and coupled dynamics of both. This is studied using the numerical method FLOW3D. Motion and stability behaviour will be different for different damage locations; hence portside, starboard-side, and aft-end bottom damage cases are considered. The effect of compartment shape and damage location on motion response and stability of the damaged ship is highlighted.

Symbiotic algae in milioline foraminifera: CO2 uptake and shell adaptations
Authors: Hansen H. J. , Dalberg P.
Published: January 2022

Experiments with living Amphisorus hemprichii demonstrated algal symbiont uptake of 14CO2 directly through the thin lateral test walls of this imperforate, porcellaneous species. An identical uptake mechanism is suggested for Sorites and Marginopora because of their similar thin lateral walls. Peneroplis, Spirolina, Cyclorbiculina, and Triloculina rupertiana show structural adaptations towards thin test walls by development of furrows and pits. These features may also enhance CO2 diffusion through the test walls for use by their symbiotic algae.
Geological perspectives of the -East Greenland continental margin
Authors: Larsen Hans Christian
Published: January 2022

The East Greenland continental margin can be divided into a northern area showing evidence for plate separation and suturing of Hudsonian, Grenvillian and Caledonian ages followed by post-Late Caledonian molasse sedimentation and Mesozoic rifting, and a southern area which apparently formed a cratonic block from the Early Proterozoic to the Middle Cretaceous. The whole margin was finally separated from the NW European margin by sea floor spreading in the latest Paleocene to earliest Eocene and now forms a rifted passive margin. The Tertiary consists of thin pre-drift sediments overlain by 1-7 km of Late Paleocene basaltic lavas extruded immediately prior to active spreading. Subsequent subsidence of the shelf led to accumulation of 2--8 km of post-basaltic sediments offshore whereas the land area was uplifted 1-2 km. Initiation of spreading along the Kolbeinsey Ridge during the late Oligocene was accompanied by renewed tectonism within the middle part of the margin. Finally the shelf was characterized by strong progradation during the Miocene. Backwards rotation of the inferred ocean-to-continent transition, through the total pole of opening, favours a slightly modified Talwani and Eldholm pole which provides a pre-drift fit of the two margins with no major overlap or gaps between the southern tip of Greenland and the Greenland-Senja Fracture Zone. Comparison of the Greenland margin and the V0ring Plateau implies a genesis for the latter, different from that proposed by Talwani and Eldholm. Minor revisions of the spreading history are presented including repeated westward displacement of the southernmost part of Mohns Ridge between anomaly 24 and 21, commencement of spreading around Kolbeinsey Ridge not later than anomaly 6 and associated activation of the recent active part of Jan Mayen Fracture Zone (JMFZ), to the north of the previous active part. The area between the fossil part of JMFZ and the recent active part including the northern part of Jan Mayen Ridge is suggested to have formed around a southern extension of Mohns Ridge active until about anomaly 6 and the predicted position of the extinct axis correlates well with bathymetry.
Isotopic evidence for a Precambrian metamorphic event within the Charcot Land window, East Greenland Caledonian fold belt
Authors: Hansen B. T. , Steiger R. H. , Higgins A. K.
Published: January 2022

Rb-Sr, U-Pb and K-Ar analyses on rocks and minerals from a tectonic window below a Caledonian thrust sheet in the westernmost part of the Scoresby Sund region (70°-72°N) give evidence for a Precambrian age of formation. The Charco't Land supracrustal sequence rests on a basement that is probably of Archaean development and older than at least 2100 m.y. The major regional metamorphism of the supracrustal rocks is probably not much older than the intrusion of two post-kinematic bodies, i.e. about 1840 m.y. Low-grade metamorphism in a tillite and low-grade retrogressive overprinting of the supra­crustal rocks are related to Caledonian orogenesis.
Nd and Sr isotope compositions from the Gardiner
Complex, East Greenland Tertiary igneous province
Authors: Nielsen Troels F. D. , Holm Paul M.
Published: January 2022

The Gardiner Complex formed during the early Tertiary opening of the North Atlantic. The complex is strongly alkaline and referred to a zone of alkaline flank magmatism 100 km west of the melting anomaly in the initial rift of the North Atlantic. Earlier investigations have documented that most rocks of the complex can be referred to three suites which are all suggested to have been formed from a single parental melanephelinitic liquid. The Nd and Sr isotope compositions presented here support this conclusion. Minor deviations are believed to be due to interaction with Archaean basement. The isotopic characteristics suggest that the alkaline magmatism originated in a source similar to that of the contemporaneous picritic and basaltic tholeiites. The isotopic composition of the source is Jess depleted than pervalent mantle (PREMA) and sets an upper enrichment limit to the composition of the Icelandic plume component 50 Ma ago.

UN LUGAR PUTREFACTO
Authors: Chávez Reyes Carlos Gabriel
Published: January 2022

Esa vez fue exactamente la última en que la plenitud de la tarde atropelló la espalda de su papá al llegar del trabajo y quedarse parado en medio de tremenda luz luego de abrir la puerta. El sol ya en total agonía hacía vislumbrar con alto estrago su silueta como tapizada de sudor y polvo, pues el hijo no sabía muy bien hasta entonces, que no sólo representaba el arduo y cansado esfuerzo de la clase obrera de siempre, sino que, colapsaba simbólicamente también esa encarnizada desigualdad de la aguda contemporaneidad inexorable del día a día que los ricos no pasan en pandemia...

Published: January 2022

El desarrollo de las nuevas tecnologías y el fenómeno de la globalización han diversificado las relaciones y las características de los medios de comunicación. Esta revolución, ha intensificado las formas de interacción entre las audiencias y los interlocutores, generando nuevos espacios de reflexión donde se crean y recrean fenómenos como la posverdad o las verdades interrumpidas. Lo anterior, ha tenido repercusiones sociales importantes como los eventos sucedidos en las elecciones de Estados Unidos en los años 2016 y 2020, así como la violenta toma del capitolio por parte de grupos seguidores del expresidente Donald Trump, en un intento de revertir los resultados de la última elección. El presente análisis es un estudio de corte exploratorio que se realizó a partir de la revisión documental y literaria sobre el tema desde un enfoque cualitativo para identificar dimensiones y conceptos asociados a este fenómeno, los cuales se abordarán a partir de la Teoría General de la Información.

O b j e c t i v e s. To develop a control system for the movement of a mobile robot along a color-contrast line, as well as to find the values of the coefficients of a proportional-integral-differentiating (PID) controller that allows the robot to move along the line at a given speed.

M e t ho d s. To adjust the values of the coefficients of the PID controller, methods of enumeration, automatic tuning and a genetic algorithm are used.

Re s u l t s. A software package for tuning the PID controller of the educational mobile robot RoboCake, designed to move along a closed color-contrast line at a given speed, has been developed. The software package consists of a simulation model of the specified robot in the Simulink environment, several virtual traces-polygons and a specialized solver based on the developed genetic algorithm. With the help of the proposed fitness function, a mobile robot control system that satisfies the stated conditions is implemented. Based on the conducted model experiments, the desired values of the parameters of the PID controller are obtained.

Co n c l u s i o n. A comparison of the effectiveness of various methods of tuning the PID controller is carried out. The developed software package is designed to solve the practical problem of moving a mobile robot along a color-contrast line at a speed of 1 m/s. The results obtained can be used to study methods of evolutionary tuning of stabilization systems for transport robots, ensuring their movement without overshoot.
Approach to optimizing charging infrastructure of autonomous trolleybuses for urban routes
Authors: Kovalyov М. Ya. , Rozin B. M. , Shaternik I. A.
Published: January 2022

P u r p o s e s.  When designing a system of urban electric transport that charges while driving, including autonomous trolleybuses with batteries of increased capacity, it is important to optimize the charging infrastructure for a fleet of such vehicles. The charging infrastructure of the dedicated routes consists of overhead wire sections along the routes and stationary charging stations of a given type at the terminal stops of the routes. It is designed to ensure the movement of trolleybuses and restore the charge of their batteries, consumed in the sections of autonomous running.

The aim of the study is to create models and methods for developing cost-effective solutions for charging infrastructure, ensuring the functioning of the autonomous trolleybus fleet, respecting a number of specific conditions. Conditions include ensuring a specified range of autonomous trolleybus running at a given rate of energy consumption on routes, a guaranteed service life of their batteries, as well as preventing the discharge of batteries below a critical level under various operating modes during their service life.

M e t ho d s. Methods of set theory, graph theory and linear approximation are used.

Re s u l t s. A mathematical model has been developed for the optimization problem of the charging infrastructure of the autonomous trolleybus fleet. The total reduced annual costs for the charging infrastructure are selected as the objective function. The model is formulated as a mathematical programming problem with a quadratic objective function and linear constraints.

Co n c l u s i o n. To solve the formulated problem of mathematical programming, standard solvers such as IBM ILOG CPLEX can be used, as well as, taking into account its computational complexity, the heuristic method of "swarm of particles".  The solution to the problem is to select the configuration of the location of the overhead wire sections on the routes and the durations of charging the trolleybuses at the terminal stops, which determine the corresponding number of stationary charging stations at these stops.
