Authors: Bachar Sitesh C. , Shafiul Kadir A.K.M. , Riajul Wahab S.M. , Al Hasan Abdullah
Published: July 2022

The variety of natural compounds is indispensable due to their mechanism
of action. For many years, natural compounds have been used to develop new classes
of chemotherapeutic agents. Chemotherapeutic agents derived and synthesised from
natural sources could be the best possible alternatives to minimise the harmful after effects of conventionally used agents against cancer, especially oral and maxillofacial
carcinoma and tumors. The proposed chapter concentrates on recent research on
various classes of natural scaffolds and their analogues that possess potent antitumor
activity. Moreover, we would like to provide an analysis of preclinical and/or clinically
investigated natural compounds. These compounds and their synthetic heterocyclic
analogues were found to be obtained through bioactivity and mechanism of action directed isolation and characterization, conjoined with modification using rational drug
design-based approaches and analogue synthesis. Structure-activity relationships,
structural change, and molecular mechanisms of action will all be examined.
Critical factors affecting Artificial Intelligence in Supply Chain Management (Case study in Danang SMEs)
Authors:   FPT University, Le Tan Trinh
Published: July 2022

This paper aims to research the elements that affect the decision to implement Artificial Intelligence (AI) in supply chain management at SMEs in Da Nang, Vietnam. The application of new technologies in supply chain management is significant during the development period of industry 4.0. A more in-depth examination of the issues in implementing AI in the supply chain will provide a more objective perspective on the challenges and benefits of adopting AI to supply chain management in SMEs. This paper investigates the effect factors in implementing Artificial Intelligence (AI) technology by constructing a Technology-Organization-Environment (TOE) framework. To achieve the research objectives, this study used two approaches. First, a qualitative approach is used to build a research hypothesis framework. Second, the quantitative approach includes explanatory factor analysis, Pearson Correlation, and regression methods by utilizing survey data on 120 MSMEs in Da Nang. The results indicated that the complexity, compatibility, cost, and external pressure factors are not essential in AI implementation. Referring to those technical factors (relative advantages), organization factors (top management support, organization readiness), and environmental factors (government support) have a positive influence on the technology implementation of AI in supply chain management.

Rotational structure of strongly interacting bands v4,v6,v7,v8, and v10 of the C2H3D molecule is spectroscopically studied. Spectra were recorded by Fourier spectrometer Brucker IFD 125HR in the laboratory of physical and theoretical chemistry of Technical University of Braunschweig. 27950 transitions with maximum values of J=40 and Ka=20 were assigned to the studied bands. The effective Hamiltonian parameters were determined in the model including the v3 resonating state. The 4028 upper energy levels were used as incoming data. They are reproduced with root mean square deviation of drms = 1.7.10-4 cm-1. Corresponding value for more than 24000 line positions is drms = 2.1.10-4 cm-1.

Published: July 2022

We investigated the resonant absorption capacity of a one-dimensional photonic crystal, the relationship between the resonant frequency and the width of its absorption band, and the composition and thickness of the layers forming it. Frequency oscillations of radiation reflection from 2.5-layer semimetal-dielectric-metal film structures caused by interference on the film thickness were studied. We measured the infrared reflection spectra of Bi87Sb13 film samples on mirror-smooth substrates with a reflective metal (Al, Ti) layer and a dielectric layer (MgF2+LiF or SiO2+Si3N4). We have developed samples that absorb up to 99.5% of radiation at maximum and integrally up to 60% of resonant thermal radiation. The composition of structures for interfacing with silicon technologies and constructing matrices of sensitive bolometric receivers has been optimized. We have proposed the implementation of active selective thermal imaging systems with matching the source and receiver of radiation simultaneously in frequency and frequency band. The analogy of the absorbing properties of film structures and the properties of human eye cells was shown.

Spectral-generation properties and the mechanism of formation of "dye-cyclodestrin" inclusion complexes for dyes of different classes (rhodamine 6G, phenalemine 160, cresyl violet) with β-cyclodextrin were studied. The effect of functional groups in the structure of dye molecules on the spectral, generation, and photochemical properties of their inclusion complexes has been studied by electron and IR spectroscopy. It has been shown that the formation mechanism consists in the entry into the β-CD cavity of only individual functional groups and substituents of dye molecules. In this case, micellar complexes consisting of several cyclodextrin molecules and dye molecules and partially intercalated complexes can be formed. The AFM method showed that the characteristic sizes of the formed nanocomplexes are 100–600 nm.

Photoluminescence spectra were studied on a naturally formed surface of a layered Cu3In5S9 crystal upon excitation by nanosecond laser radiation. At relatively low levels of optical excitation intensity, luminescence quenching was observed near a photon energy of 1.636 eV in a narrow energy band near 118 meV. This phenomenon is explained by the formation of bound triplet excitons and their dissociation with the emission of phonons. It is shown that, as the intensity of the optical excitation of the crystal increases, the impurity emission band in the crystal disappears. The photocurrent spectrum of Cu3In5S9 at 295 K is formed by peaks at energies of 1.53 and 1.81 eV. The lifetime of nonequilibrium electrons through fast centers is ~20 ns. From the temperature dependence of the electrical conductivity of the Cu3In5S9 crystal in the range 110–350 K, the activation energies of two donor levels, 0.28 and 0.76 eV, were determined. Keywords: Cu3In5S9, photoluminescence, photocurrent, electrical conductivity.

Authors: Тихонов K.С. , Рот А.
Published: July 2022

A generalized model of the continuously generating superradiant Raman laser is considered. The model includes competing individual and cooperative atomic processes arising from the interaction of atoms with external light fields. We show that proper selection of the model parameters leads to cooperative effects in the atomic active laser medium. We calculate the steady state values ​​of the atomic polarization and two-atoms correlations. Using the quantum regression theorem, we determine the spectral characteristics of the collectively emitted light. We use cumulant expansion to estimate the higher-order correlations between atoms.

Published: July 2022

A physical situation is proposed and theoretically analyzed, in which, in our opinion,
it is possible to generate unipolar terahertz pulses with a large electric area. In this case, the gas in the tube is excited by a femtosecond IR laser pulse. In this case, the tube with gas is placed in a constant external electric field. The generation of a unipolar pulse is based on ”three-step scheme" - ionization of gas atoms by a femtosecond pulse, subsequent acceleration of a free electron in a dc external field and subsequent
annihilation of an electron upon collision with a tube wall or another atom (ion).

We discuss photoelectrical properties of an on-chip attenuated total reflection (ATR) sensor for the ethanol concentration measurements in an aqueous solution. The on-chip sensor/microchip was made from a p-InAsSbP/n-InAs monolithic double heterostructure with three mesas/individual diodes grown on a single n⁺-InAs substrate/waveguide. Two heterostructure diodes were used as photodiodes, while the third one - as a LED. The ethanol concentration was measured via an algorithm based on analysis of the I–V characteristic parameters of a photodiode and the L–I characteristics of an LED.

Особливості поліморфізму гена AРОE в пацієнтів з аритміями залежно від вираженості когнітивних розладів
Authors: Stadnik S.M.
Published: July 2022

Актуальність. Носії поліморфізму APOE4 мають підвищений ризик зниження когнітивних функцій. Мета дослідження: вивчити взаємозв’язок між генетичними (поліморфізм гена APOE) показниками та розвитком когнітивних розладів у пацієнтів з аритміями. Матеріали та методи. Провели порівняльний аналіз частоти генотипів та алелей поліморфних варіантів гена APOE в 110 пацієнтів віком від 30 до 75 років (у середньому 63,8 ± 4,3 року): 86 осіб із когнітивними порушеннями на фоні різних форм аритмій становили основну групу, контрольна група включала 24 хворі з аритміями без когнітивних розладів. Результати. Переважання ε3/ε3 генотипу встановили в 57 % пацієнтів iз когнітивними розладами та в 54,2 % без когнітивних порушень (p = 0,07). Найменш поширеним був ε4/ε4 генотип, частота якого при когнітивних розладах становила 5,8 %, у пацієнтів без когнітивних розладів його не знаходили (p < 0,001). Серед гетерозиготних генотипів ε3/ε4 виявили в 19,8 % пацієнтів iз когнітивними розладами та в 16,6 % — без зниження когнітивних функцій (p = 0,06); ε2/ε3 — в 11,6 і 20,8 % (p = 0,026) відповідно. У пацієнтів із легкими когнітивними розладами існувала тенденція до накопичення генотипів ε2/ε3, ε3/ε3 і зниження генотипів ε2/ε4, ε3/ε4, що не досягало рівня статистичної вірогідності порівняно з особами без когнітивних порушень (p = 0,06). Серед пацієнтів із помірним зниженням когнітивних функцій немає носіїв генотипів ε2/ε2 і ε2/ε3, а також збільшена частота носійства генотипів ε3/ε4, ε4/ε4 (р = 0,034). Висновки. Носійство алеля ε4 АРОЕ є додатковим чинником, що збільшує ризик розвитку когнітивних порушень у пацієнтів з аритміями, носійство алеля ε2 можна вважати протективним чинником щодо розвитку когнітивних розладів.
ANALIZA INSTITUCIONALNIH DETERMINANTI POLITIKE PRIVLAČENJA STRANIH DIREKTNIH INVESTICIJA U SRBIJI
Authors: Tmusic Marko , Rapaic Stevan
Published: July 2022

Ovaj rad se bavi analizom institucionalnih determinanti kao podsticajnih mera za privlačenje stranih investicija u Republici Srbiji. Posebna pažnja se posvećuje institucionalnim faktorima kao što su politička i ekonomska stabilnost, nivo korupcije, efikasnost sudstva, zatim stabilan i pouzdan, ujedno i transparentan zakonski okvir, kojima se pokušava objasniti ponašanje stranih investitora prilikom izbora destinacije u koju žele investirati. U radu će se pokazati da se institucionalni nedostaci Srbije pokušavaju nadomestiti politikom subvencionisanja, čija se ekonomska efikasnost dovodi u pitanje, a posledica je upravo institucionalne neefikasnosti srpskog političkog i ekonomskog sistema. Osnovna intencija rada je da ukazivanjem na institucionalne prepreke za veći priliv stranih investicija, ponudi i jasne smernice za razvoj mera i mehanizama za privlačenje onih stranih investitora, izvozno orijentisanih, a koji dugooročno planiraju da ostanu u Republici Srbiji.
NOVE POLITIČKO–EKONOMSKE INICIJATIVE NARODNE REPUBLIKE KINE I SJEDINJENIH AMERIČKIH DRŽAVA U CENTRALNOJ AZIJI: DIPLOMATSKE PLATFORME „KINA+5” I „C5+1”
Authors: Trailovic Dragan
Published: July 2022

Rad se bavi novim diplomatskim platformama za saradnju Narodne Republike Kine i Sjedinjenih Američkih Država sa centralnoazijskim regionom u formatu „5+1”. Ova dva formata saradnje sagledavaju se u kontekstu unutarregionalnih promena u političkoj strukturi Centralne Azije, pre svega promena u vezi sa tranzicijom vlasti u centralnoazijskim republikama i pokretanja konsultativnih sastanaka lidera država Centralne Azije sa ciljem unapređenja regionalnog povezivanja. Za analitički okvir uzimamo onu grupu literature koja na međunarodne odnose i procese u ovom regionu gleda kroz prizmu Engleske škole međunarodnih odnosa, posebno se oslanjajući na koncept „međunarodnog društva”. Polazimo od tvrdnje da i same države Centralne Azije imaju značajan uticaj na procese u političko-ekonomskoj strukturi regiona isto kako ga imaju i veliki geopolitički igrači. Cilj rada je da, uzimajući u obzir regionalni spoljnopolitički kontekst i promene u njemu, a preko diplomatskih platformi „Kina+5” i „C5+1”, oslika deo nove geopolitičke dinamike u regionu. Zaključuje se da NR Kina preko ove diplomatske platforme u svoje odnose sa regionom uvodi i političku komponentu saradnje uz novi pristup regionu kao integralnoj celini, dok SAD nastoje da oživljavanjem diplomatske platforme „C5+1” ostvare integraciju Avganistana u region, kao i da Centralnoj Aziji pruže protivtežu kineskom i ruskom uticaju i ojačaju svoju poziciju u regionu.
MAĐARSKI IZBORI 2022: PROMENA KOJA NIJE DOŠLA
Authors: Bursac Dejan
Published: July 2022

Parlamentarni izbori održani u Mađarskoj 3. aprila 2022. bili su prvi od 2006. godine koji su obećavali dozu povećane kompetitivnosti, pa čak i neizvesnosti; a svakako prvi od početka drugog premijerskog staža Viktora Orbana (od 2010. godine) na kojima se opozicija nadala relativnom uspehu. Takvu nadu je opravdalo nekoliko faktora: opozicione stranke su po prvi put nastupile zajedno na parlamentarnim izborima i istakle nezavisnog i srednjem glasaču bliskog konzervativnog kandidata, a uostalom, na lokalnim izborima dve i po godine ranije, ostvaren je uspeh osvajanjem vlasti u Budimpešti i još deset gradova. Pritom, ionako kontroverzna međunarodna pozicija iliberalnog Orbanovog režima počela je dodatno da se komplikuje sa ukrajinskom krizom, koja je izbila na samom početku izborne kampanje. Teorija predizbornih koalicija ističe da je u takvoj situaciji racionalno da se opozicioni akteri udruže i maksimizuju svoj uspeh, posebno jer institucionalni okvir izbora u Mađarskoj kao zemlji sa dominantnom partijom nije pogodan za fragmentiranu opoziciju. Uprkos tome, rezultat izbora 3. aprila uveče je bio ubedljiv: vladajući Fides je ostvario najveću izbornu pobedu od obnove višepartizma i osvojio 135 od 199 mesta u parlamentu.
DEMOCRACIES, GREY ZONES, HYBRID REGIMES-CLIMBING THE BABEL OF TERMINOLOGY
Authors: Böcskei Balázs , Hajdu Nóra
Published: July 2022

The objective of the paper is to provide a distinction of the often partially or completely overlapping hybrid regime terms and to discuss the notions and concepts related to the discourse on hybrid regimes. The clarification of grey zone related definitions is highly justified due to the existing rich Babelian terminology as well as the potential benefit of having a clearer view on the contradictions and limitations inherent to traditional democracy interpretations. There is a scientific consensus on the grey zone between democracy and autocracy forming its own regime type, but the different approaches apply various terms to it. Using country examples arching over eras, we demonstrate that the adjective “hybrid” actually represents a threshold indicating if a given system reaches the level above which it may be considered democratic. After identifying this level and its elements, the study also discusses how different regimes relate to elections in order to determine the institutional conditions for the stability or replacement of a regime.
ANALIZA KONCEPTA INKLUZIJE U KONTEKSTU OBRAZOVNE POLITIKE
Authors: Beric Jovan
Published: July 2022

Politika inkluzivnog obrazovanja deo je šire politike stvaranja inkluzivnijeg, pravednijeg, humanijeg, tolerantnijeg i demokratičnijeg društva. S obzirom na to da deca kroz obrazovanje usvajaju brojne stavove koji će oblikovati njihov život u budućnosti veoma je važno adekvatno pristupiti procesu inkluzivnog obrazovanja. Budući da se poslednjih godina u pogledu implementacije ovog procesa vode brojne rasprave svrha ovog rada je da postavi jasne teorijske temelje, definiše pojam i otkloni nejasnoće u odnosu da slične termine, kako bi se mogla formulisati jasna obrazovna politika i preduzeti mere za njenu adekvatnu primenu.
U skladu sa tim u prvom delu rada pravi se distinkcija između medicinskog i socijalnog modela, a zatim se razmatraju teorijski pravci i principi na kojima se zasniva koncept inkluzije. U tom kontekstu analizirana su i međunarodna dokumenta koja čine osnovu za kreiranje nacionalnih inkluzivnih obrazovnih politika. Imajući u vidu da je svrha ovog koncepta da se kroz njegovu operacionalizaciju i implementaciju poboljša položaj marginalizovanih grupa, u poslednjem delu rada jasno su određene ključne odlike inkluzivnog obrazovanja, te je napravljena distinkcija u odnosu na pojam integracije. Analiza naučne literature, kao i međunarodnih dokumenata dovodi do zaključka da je obrazovna inkluzija jedan dinamičan proces koji ne podrazumeva samo uključivanje marginalizovanih društvenih grupa kroz pravnu regulativu u redovne škole, već permanentan rad na prilagođavanju okoline i društva potrebama tih grupa. Takođe, zaključuje se da je nemoguće kreirati potpuno inkluzivni sistem. Stoga je važnije stvoriti ekonomske, političke i društvene uslove koji će pružiti jednake mogućnosti i šanse za razvijanje maksimalnih potencijala svake individue. Ovaj rad treba da pruži doprinos ne samo naučnoj zajednici, već i nastavnicima i donosiocima odluka kako bi bolje razumeli koncept i trasirali put za sprovođenje pre svega obrazovnih, ali i svih drugih politika u društvu. Obrazovanje je temelj svake nacije, a put kojim deca prođu tokom školovanja odrediće njihovu budućnost.
PRITAJENI TIGAR, NESKRIVENI ZMAJ: KINA – RAZVOJ, USPON I GLOBALNI UTICAJ Osvrt na knjigu prof. dr Dragane Mitrović
Authors: Matijevic Andrea
Published: July 2022

Globalna finansijska kriza iz 2008. godine suočila je svet sa novom realnošću. Period zatišja i saniranja posledica ove krize dodatno je potvrdio izvesnost sumnji o umanjenoj globalnoj ekonomskoj dominaciji SAD. Priznanje značaja rastućih ekonomija i njihove uloge na svetskom nivou postala je neminovnost. Pre svega, takav značaj se morao priznati Kini, a čini se da je ova kriza bila neophodna da bi uspon i razvoj Kine bio napokon prihvaćen kao nesporna činjenica. Nakon krize, na globalnom nivou je uspostavljen konsenzus o tome da Kina više ne može biti posmatrana kao akter na marginama svetskih ekonomskih procesa, već kao jedan od najvažnijih aktera u međunarodnim ekonomskim odnosima.

Abstract: In this paper, we are going to see about the project against poaching. Now a days there are many incidents about smuggling of trees like sandal, sawn etc. These trees are very costly and meager. They are useful in medical science, cosmetics etc. To restrict their smuggling and to save forest from forest fire, deforestation around the globe some preventive measures have been developed. The proposed system makes use of electronic devices such as controllers and sensors. Tree cutting will be sensed by metal detector and this information will be displayed on LCD which is placed in the main server unit. Simultaneously buzzer will be activated and the data will be transmitted to the senior office using NRF receiver module. Communication between tree using NRF transmitter and receiver module.

Authors: Altaf Mohammad
Published: July 2022

Abstract: Modern classifiers based on convolutional neural networks (CNNs) have been shown to categorise photos of skin cancer on par with dermatologists, potentially enabling lifesaving and rapid diagnosis even outside of the hospital via mobile app installation. There is currently no overview of current research in this field that we are aware of. We searched the Google Scholar, PubMed, Medline, Science Direct, and Web of Science databases for systematic reviews and original research publications published in English. In this evaluation, only publications with appropriate scientific proceedings were considered. CNNs perform admirably as cutting-edge skin lesion classifiers. Unfortunately, comparing different categorization algorithms is difficult because some approaches use non-public datasets for training and/or testing, which makes repeatability problematic. Future papers should use publicly available benchmarks and fully describe the training methodologies used to allow for comparison

Published: July 2022

Abstract: VANETs (vehicular ad hoc networks) have become an essential component of current intelligent transportation systems (ITS). However, under the influence of hostile mobile vehicles, security threats pose a threat to offloading vehicle duties to the cloud server. How to address the complicated computation offloading of vehicles while assuring the cloud server's high security is an essential research subject. We investigated the safety and offloading of a multi-vehicle ECCO system based on cloud blockchain in this research. To begin, we present a distributed hierarchical software-defined VANET (SDVs) framework to construct a security architecture in order to attain agreement in the vehicular context. Second, to increase offloading security, we suggest using blockchain-based access management, which protects the cloud from unauthorised offloading. Finally, we decide task offloading by jointly optimising offloading decisions, consensus mechanism decisions, computation resource allocation, and channel bandwidth to tackle the intense computing problem of approved vehicles.
