Published: January 2022

Named Data Networking (NDN) is a model that has been proposed by many researchers to alter the long-established IP based networking model. It derives the content centric approach rather than host-based approach. This is gaining even more traction in the wireless network and is able to replace the conventional IP-based networking. Up to now, NDN has proven to be fruitful when used with certain limitations in vehicular networks. Vehicular networks deal with exchanging information across fast moving complex vehicle network topology. The sending and receiving of information in such a scenario acts as a challenge and thus requires an effective forwarding strategy to address this problem. Different research work has provided with multiple forwarding strategy that solves the current problem up to some limit but further research work is still longed for to get an optimum solution. This paper provides a brief survey on current existing forwarding strategies related to vehicular networks using NDN as well as providing information on various resources and technologies used in it.

Authors:   Department of Informatics, Faculty of Science and Technology, Sanata Dharma University, Kumalasanti Rosalia Arum
Published: January 2022

Humans are social beings who depend on social interaction. Social interaction that is often used is communication. Communication is one of the bridges to connect social relations between humans. Communication can be delivered in two ways, namely verbal or nonverbal. Handwriting is an example of nonverbal communication using paper and writing utensils. Each individual's writing has its own uniqueness so that handwriting often becomes the character or characteristic of the author. The handwriting pattern usually becomes a character for the writer so that people who recognize the writing will easily guess the ownership of the related handwriting. However, handwriting is often used by irresponsible people in the form of handwriting falsification. The acts of writing falcification often occur in the workplace or even in the field of education. This is one of the driving factors for creating a reliable system in tracking someone's handwriting based on their ownership. In this study, we will discuss the identification of a person's handwriting based on their ownership. The output of this research is in the form of ID from the author and accuracy in the form of percentage of system reliability in identifying. The results of this study are expected to have a good impact on all parties, in order to minimize plagiarism. Identification of handwriting to be built consists of two main processes, namely the training phase and the testing phase. At the training stage, the handwritten image is subjected to several processes, namely threshold, wavelet conversion, and then will be trained using the Backpropagation Artificial Neural Network. In the testing phase, the process is the same as in the training phase, but at the end of the process, a comparison will be made between the image data that has been stored during training with a comparison image. Backpropagation ANN can work optimally if it is trained using input data that has determined the size, learning rate, parameters, and the number of nodes on the network. It is expected that the offered method can work optimally so that it produces an accurate percentage in order to minimize handwriting falcification.
Risks of Antidepressant induced psychotic events in patients with depression and psychosis
Authors: Dakua Sourav
Published: January 2022

The aim of this ‘literature review’-based argumentative paper has been to find out the risks of developing psychotic and depressive disorders in patients having been treated with antidepressants. In order to reach a resounding supposition, this literature review-based argumentative study had taken an incisive look into previous research works and meta-analysis, which in effect had underscored the risks of antidepressant-induced psychotic and depressive disorders in patients with depression as well as psychosis even as the protagonists of antidepressant drug classes could not be undermined given their upscaled magnitude of benefits. While following a probing interpretation of past studies, this might be demystified that antidepressants could lead to psychotic events and depressive disorders in patients of all age groups with children and young adults being more susceptible to develop psychosis. The psychotic episodes could even be developed during initial phase of treatments in patients suffering from depressive and psychotic disorders such as bipolar mood disorder, unipolar depression, major depressive disorders, mania, OCD (Obsessive Compulsive Disorder), delusional depression (psychotic depression), schizophrenia, schizoaffective disorders alongside multiple somatic symptoms among others as well. Concomitantly, with efficaciousness of antidepressants in major depressive disorder still remaining a subject to utter dubitability, different antidepressant drug classes were found to be associated with a considerable scale of adverse effects after carrying out protracted arguments on findings of evidence-based past studies, meta-analysis of previous researches and relevant clinical cases. Therefore, following a systematized approach towards past studies, this argumentative research has reached a coherent conclusion that antidepressants are likely to cause psychotic events and exaggeration of depressive disorders up to some extent in several cases. Hence, there is a stipulation of individual risk-benefit assessment and intricate history taking in patients being contemplated for antidepressant drugs alongside a close observation and follow-up in patients of all age groups after introducing antidepressant medications.

Published: January 2022

Coal mining activities have affected the soil and vegetation conditions on the mined land. Revegetation of ex-mining land is a must to balance environmental functions. The choice of plants must be adapted to the conditions of the ex-mining land so that growth continues. The use of local plants for revegetation is fascinating to study. This study aimed to investigate the soil characteristics of ex-coal mining land and bamboo growth as a plant used for revegetation. Bamboo is collected from around the former coal mining area. Bamboo growth is observed through its branching for 12 weeks of measurement. Soil is analyzed based on its physical and chemical properties. The Schmidt-Ferguson method was used to analyze the climate type in the study area. The results of the soil analysis show that the plants can still grow for revegetation. Of the three types of bamboo observed (Schizostachyum brachycladum kurz, Dendrocalamus asper, and Gigantochloa robusta), Schizostachyum brachycladum kurz is the best growing bamboo in ex-coal mining land with a branch length of 42 cm in 12 weeks of measurement. The climate in the ex-coal mining area studied is a wet type (Q = 0.184). Bamboo is a suitable plant for revegetation, especially in coal mining areas in South Sumatra, Indonesia.

Coal mining can disrupt the balance of the ecosystem, including the soil environment ecosystem as a habitat for soil arthropods. This study aims to see the soil arthropod family, relative density, diversity, dominance and evenness of soil arthropods in the revegetation area of the ex-mining area of PT. Bara Alam Utama. The re-search was conducted in the revegetation area of the former coal mine area of PT. Bara Alam Utama in Lahat district, South Sumatra. The research area consists of 8 location points, namely natural areas, revegetation areas of age 7,6,5,4,3,2 and 1 year. The study was conducted using an exploratory survey method, sampling was car-ried out based on the purposive sampling method by drawing a 100 m long transect with 5 sample plots inside measuring 20 x 10 m at each revegetation age. The results showed that the highest soil arthropod diversity index was found at the 3 year old revegetation location (H = 0.915) and the highest soil arthropod evenness index was at the 3 year old revegetation location (e = 0.17), while the highest soil arthropod dominance index was at 5 year old revegetation location (D = 0.886) which causes the 5 year revegetation location to have the lowest soil ar-thropod diversity index and evenness index (H = 0.351 and e = 0.054), while the lowest soil arthropod domi-nance index value is at the 3 year old revegetation location (D = 0.667), so it can be seen that there is a correla-tion between the diversity index and the evenness index of soil arthropods where both are inversely proportional to the results of the calculation of the dominance index. The high and low diversity index at each research loca-tion is influenced by abiotic factors (pH, soil temperature and soil moisture), age of revegetation and type of vegetation

Published: January 2022

Sumatran elephant is a subspecies of endemic Asian elephants on the island of Sumatra and is included in the Red List of the International Union for Conservation of Nature (IUCN) with critically endangered status. The building of the Elephant Training Centre (ETC) in Way Kambas National Park (WKNP) is one of the conservation efforts of Sumatran elephants. Small and closed population size lead to an increased risk of inbreeding that triggers reduction in genetic variation and viability and increases the risk of extinction. The phylogenetic pattern of Sumatran elephants in Indonesia has shown a low population genetic diversity. Genetic diversity information is indispensable to support the direction of decision making in Sumatran elephant conservation policy. The DNA isolation of Sumatran elephants in ETC, WKNP has performed as a first step to trace its genetic variation. The advanced step of DNA isolation is the use of cytochrome oxidase subunit I (COI) gene for identification of genetic characteristics in Sumatran elephants. The COI gene is one of the genes on the mitochondrial genome and in molecular studies it is used as a genetic marker to study genetic characteristics between species and individuals. Identification and characterisation are done by sequencing process and data analysis in the form of electroforegram using Molecular Evolution Genetics Analysis (MEGA) software version 6.0. to see the genetic diversity of the female Sumatran elephant population in ETC, WKNP. Based on the results of the analysis it is indicated that the genetic distance of 24 individual female Sumatran elephant from PLG, TNWK is 0.000 with a homology value of 100%, strengthened by the construction of phylogenetic tree. The absence of genetic distance indicates a close genetic relationship, so it can be concluded all individual female Sumatran elephants in the PLG, TNWK is derived from one population group.

Published: January 2022

Swampy land is an alternative for rice plant cultivation where the amount of rainfall has an impact on the amount of inundation. In order to provide appropriate water for rice plants, especially during the dry season, an irrigation water system is required for its control.Alternative materials such as dry rubber latex and vermicom-post can be utilized to reduce water use and ensure that water is delivered as efficiently as possible. The goal of this study was to see how dried rubber latex on the soil surface and vermicompost in the soil affected rice plant water demand and growth. This research was conducted from November 2020 – February 2021. The study used a factorial randomized block design (RAKF) with 2 treatments, covered dry rubber latex variations (K), K0 (0%), K1 (25%), K2 (50%), K3 (75%), and vermicompos (V), V0(0 g), V1(58.82 g), V2(117.64 g), V3 (176.46 g)with 3 rep-licat. So that the total treatmentsare 48 treatments.The results showed that the application of dry rubber latex and vermicompost significantly affected the number of leaves and the number of tillers. The K3 treatment (75%) was the best because it had the smallest evapotranspiration rate with an average of 1.2 mm day-1. The K3 treatment (75%) had the smallest average water requirement of 1.6 mm day-1 with an average number of 37.07 leaves. The high yield of K3 treatment was due to the wider the area covered by 75% (K3), the higher the water content, nutrients, and the lower the soil temperature. Closure using dry rubber latex can reduce sunlight so that the process of water loss is lower, and the available nutrients are higher.

Can money be compared to energy? Empirical analysis of making money with the E = mc2 logic
Authors: KARACAN Rıdvan , BARIŞ İsmail
Published: January 2022

In this study, the E = mc2 principle that energy can be derived from mass and energy as itself was adapted for money. In the study, it was meant to provide a natural dimension to not using money other than the intent of exchange and the necessity of earning money by producing. To this end, the effect of foreign direct investments that are representing production and portfolio investments' effects on economic growth as representing monetary activities. The findings showed that both in the long and short term, there is a positive and significant relationship between FDI and economic growth. No such relationship has been found for portfolio investments. This result coincides with the E = mc2 relationship.
On a property of the ideals of the polynomial ring $R[x]$
Authors: AL-MAKTRY Amr Ali Abdulkader
Published: January 2022

Let RR be a commutative ring with unity 1≠01≠0. In this paper we introduce the definition of the first derivative property on the ideals of the polynomial ring R[x]R[x]. In particular, when RR is a finite local ring with principal maximal ideal m≠{0}m≠{0} of index of nilpotency ee, where 1<e≤|R/m|+11≤e≤|R/m|+1, we show that the null ideal consisting of polynomials inducing the zero function on RR satisfies this property. As an application, when RR is a finite local ring with null ideal satisfying this property, we prove that the stabilizer group of RR in the group of polynomial permutations on the ring R[x]/(x2)R[x]/(x2), is isomorphic to a certain factor group of the null ideal.
Beyond Knuth's notation for unimaginable numbers within computational number theory
Authors: LEONARDIS Antonino , D'ATRI Gianfranco , CALDAROLA Fabio
Published: January 2022

Literature considers under the name "unimaginable numbers" any
positive integer going beyond any physical application. One of the most known
methodologies to conceive such numbers is using hyper-operations, that is a
sequence of binary functions dened recursively starting from the usual chain:
addition - multiplication - exponentiation. The most important notations to
represent such hyper-operations have been considered by Knuth, Goodstein,
Ackermann and Conway as described in this work's introduction. Within this
work we will give an axiomatic setup for this topic, and then try to nd on one
hand other ways to represent unimaginable numbers, as well as on the other
hand applications to computer science, where the algorithmic nature of representations and the increased computation capabilities of computers give the
perfect eld to develop further the topic, exploring some possibilities to effectively operate with such big numbers. In particular, we will give some axioms
and generalizations for the up-arrow notation and, considering a representation via rooted trees of the hereditary base-n notation, we will determine in
some cases an effective bound related to "Goodstein sequences" using Knuths
notation. Finally, we will also analyze some methods to compare big numbers,
proving specically a theorem about approximation using scientic notation
and a theorem on hyperoperation bounds for Steinhaus-Moser notation.
Counting non-isomorphic generalized Hamilton quaternions
Authors: GRAU Jose Maria , MIGUEL Celino , OLLER-MARCEN Antonio M.
Published: January 2022

In this paper we study the isomorphisms of generalized Hamilton quaternions $\Big(\frac{a,b}{R}\Big)$ where $R$ is a finite unital commutative ring of odd characteristic and $a,b \in R$. We obtain the number of non-isomorphic classes of generalized Hamilton quaternions in the case where $R$ is a principal ideal ring. This extends the case $R=\mathbb{Z}/n\mathbb{Z}$

where $n$ is an odd integer.
The Battle Within and the Battle Without: The Posthuman Worldview of Ken MacLeod’sThe Corporation WarsTrilogy
Authors: PATRA INDRAJIT
Published: January 2022

The present essay seeks to analyze Scottish science fiction writer Ken MacLeod’sThe Corporation Warstrilogy (2016-2017) as an amalgam of politico-philosophical ideas set against the background of posthumanism. MacLeod’s far-future posthuman world-building relies on the conventional tropes of science fiction (man-machine hybrids, brain uploading, digital resurrection, and the agency of sentient machines) to engage with pressing ideologies (the master-slave dialectics, the historical perpetuation of age-old conflict between progressive and reactionary forces, the ethics of machinic consciousness). MacLeod’s novels project a postbinarist worldview where outmoded binary oppositions between life and death, the real and the virtual, the human and the machinic are constantly abolished, but which still preserves persistent ideological divisions.
Homes for Canadians (II)
Authors: HOWARD DAVID BRIAN
Published: January 2022

According to Giorgio Agamben, the Greek term for ‘habitual dwelling place,’ or ‘habit,’ is ethos. The rise to prominence in the twentieth century of the modern idea of the suburb, or ‘suburbia,’ held open the door to the potential realization of the American (and Canadian) dream ethos of universal home ownership. The tantalizing appeal of a the ideal of ‘home’ and ‘homeland’ have become key terms in the Post World War Two pursuit of a mode of ‘dwelling’ linked to consumer capitalism. Yet for Frankfurt School critics such as Theodor W. Adorno, the pursuit of this suburban ideal induced a deep sense of ennui such that to feel ‘at home’ in such a suburban environment challenged the very foundations of the dwelling place of Western civilization. “It is part of morality,” Adorno concluded in his book, Minima Moralia, “not to be at home in one’s home.” This text is an exercise in examining this question of ‘dwelling’ and ‘home’ through an allegorical poetical focus (drawn from Walter Benjamin and Charles Baudelaire) focusing on a newly completed suburb in the Canadian city of Halifax, Nova Scotia.
Isolation of MDCK cells with low expression of mdr1 gene and their use in membrane permeability screening

Published: January 2022

The Madin-Darby canine kidney (MDCK) cell line is frequently used for permeability screening in drug discovery. It contains endogenous transporters, most prominently canine multidrug resistance P-glycoprotein (Mdr1), which can interfere with studies of P-glycoprotein substrate assessment and permeability measurements. Because MDCK wild type (WT) is genetically heterogeneous, an isolation procedure was investigated in this study to obtain the subclonal line with low P-glycoprotein expression. The best clone obtained had up to 3-fold lower amprenavir efflux and P-glycoprotein expression in comparison to WT. Of 12 standard compounds tested that exhibited active efflux in WT cells, 11 showed a decrease in efflux in the isolated clone. However, the decrease was not below the cut-off value of 2, indicating residual P--glycoprotein activity. Clone isolation via the limiting dilution method, combined with bidirectional amprenavir permeability for clone selection, successfully identified MDCK clones with substantially lower P-glycoprotein efflux and has been demonstrated as a useful tool for assessing passive permeability in early drug discovery.

Sophora japonica is a source of several flavonol, flavone and isoflavone glycosides that are reported to positively affect menopausal symptoms including osteoporotic complications. In the present study fructus Sophorae extract (FSE) was administered orally for three months at a dose of 200 mg kg–1 in ovariectomized (OVX) New Zealand rabbits. 3D computed tomography scans and histopathological images revealed microstructural disturbances in the bones of the castrated animals. FSE recovered most of the affected parameters in bones in a manner similar to zoledronic acid (ZA) used as a positive control. The aglycones of the main active compounds of FSE, daidzin, and genistin, were docked into the alpha and beta estrogen receptors and stable complexes were found. The findings of this study provide an insight into the effects of FSE on bone tissue loss and suggest that it could be further developed as a potential candidate for the prevention of postmenopausal osteoporotic complications.
Potential of germanium-based compounds in coronavirus infection

Published: January 2022

The first germanium compounds which exhibited immunomodulatory and antiviral effects were sesquioxane-type germanates. To date, more than a dozen compounds containing germanium have been synthesized and are being actively studied. They include germanium carboxylates and citrates, complexes of germanium with resveratrol, daphnetin, mangiferin, chrysin, quercetin, ascorbic and nicotinic acids, amino acids, gamma-lactones, germanium-containing spirulina, yeast and others. Germanium-based compounds have shown the ability to influence the replication of various DNA/RNA viruses, stimulate the body’s natural resistance, prevent the development of metabolic intoxication of various origin, increase the efficacy of vaccines, and prevent the development of excessive accumulation of reactive oxygen species, which plays a decisive role in the development of inflammatory response caused by a viral infection. It seems reasonable to say that germanium-based complex compounds effectively contribute to the preservation of high--energy bonds in the form of ATP, optimize the activity of metabolic processes by re-oxygenation, and exhibit antimicrobial activity. The purpose of this review is to summarize the pharmacological potential of various germanium-based compounds studied nowadays, taking into account their mechanisms of action, and to analyze their prospects in the development of integrated approaches in the prevention and treatment of SARS-CoV-2 infection.
