An Energy-Efficient Scheme for IoT Networks
Authors: Alhussain Thamer
Published: January 2023

With the advent of the Internet of Things era, "things-things interconnection" has become a new concept, that is, through the informatization and networking of the physical world, the traditionally separated physical world and the information world are interconnected and integrated. Different from the concept of connecting people in the information world in the Internet, the Internet of Things extends its tentacles to all aspects of the physical world. The proposed algorithm considers the periodical uplink data transmission in IEEE 802.11ah LWPAN and a real-time raw settings method is used. The uplink channel resources were divided into Beacon periods after the multiple nodes send data to the access point. First, the access point predicted the next data uploading time during the Beacon period. In the next Beacon period, the total number of devices that will upload data is predicted. Then, the optimal read-and-write parameters were calculated for minimum energy cost and broadcasted such information to all nodes. After this, the data is uploaded according the read-and-write scheduling by all the devices. Simulation results show that the proposed algorithm effectively improved the network state prediction accuracy and dynamically adjusted the configuration parameters which results in improved network energy efficiency in the IoT environment.
Wireless DF Relaying with Beamforming for an Unmanned Aircraft System over ??? Fading Channels
Authors: Kumar Ramesh , Hussain Ayaz , Aziz Abdul , Joe Inwhee
Published: January 2023

In this paper, we propose a dual-hop decode-and-forward (DF) relaying network with beamforming for an unmanned aircraft system (UAS) over ??? fading channels. The ?–? fading model is a general fading model that models wireless fading channel perfectly in line-of-sight (LOS) propagation environments and includes Nakagami-m, Rician, Rayleigh, and One-sided Gaussian fading channels as special cases. We consider an unmanned aerial vehicle (UAV) as a moving relay for forwarding the data signals from a source ground station (GS) to a destination GS. Our proposed system considers multiple antennas at the source and destination, whereas the relay has a single antenna. We derive a closed-form expression for the outage probability in terms of the generalized Marcum Q-function. We carry out the performance analysis by means of derived expression for the various antenna arrangements, distinct values of radius, and different values of fading parameters. Our results show that the number of antennas and fading parameters, ? and ?, have a positive relation with system performance. The analytical results are validated through Monte Carlo simulations.
Integrating and Securing Video, Audio and Text Using Quaternion Fourier Transform
Authors: ElSharkawy Magdy Ibrahim
Published: January 2023

The rapid growth of communication technology encouraged a rapidly rising demand for Internet connectivity. Accordingly, this led to an upsurge in research in the discipline of information security. cryptography plays a significant role in securing and verification of information exchanged via public communication channels.   The current paper introduces a novel approach for combining both video, audio and text signals into a single architecture and securing it prior to the process of transmission.  The idea behind this approach depends on embedding the color components of each pixel of the video signal in a quaternion number. The fourth component of the quaternion number is occupied with either an audio sample or a textual data.   The array of quaternion numbers corresponding to a video frame is converted to the frequency domain, using quaternion Fourier transform,  and then multiplied by the quaternion Fourier transform of a digital image. Herby, the selected digital image is used as a complicated secret. The yielded signal is transmitted and when received, both of video, audio and text signals are extracted using simple quaternion mathematics applied to the received signal and a copy of the digital image.    A second level of complexity can be added to this approach by applying one of the well-known cryptographic techniques (symmetric or asymmetric) to the samples of the transmitted signal.   The suggested approach is implemented using Matlab simulation software and the extracted signals are compared with the original ones using some performance metrics.  The obtained results show that the proposed approach is robust and more secure against cryptanalysis attacks without affecting the used bandwidth of the communication channel.
Deployment of Multi-Fuzzy Model Based Routing in RPL to Support Efficient IoT
Authors: Aljarrah Emran
Published: January 2023

IPv6 routing protocol for Low Power Lossy Network (LLN) is known as RPL protocol designed for the Internet of Things. In RPL, multicasting is performed by using SMRF and BMRF algorithm. These conventional multicast algorithms were not able to suppress the duplicate packets which minimize the Quality of Service (QoS) especially delay metric. Hence the main focus of this paper is to address the use of the RPL routing protocol, by proposing an objective function based on fuzzy logic. In RPL QoS is constructed by Destination Oriented Directed Acyclic Graph (DODAG) that plays a major role. The defined Objective function is achieved by novel Multi-fuzzy Logic (Ml-FL) model which includes three significant categories of metrics as (i) node oriented metrics, (ii) channel oriented metrics and (iii) link oriented metrics. Each metric is defined with three other parameters for effective parent node selection. To solve the complexity of Fuzzy logic, parallel processing of multiple fuzzy logic blocks is proposed. An enhanced-BMRF algorithm is proposed with the minimum of delay and duplicate packets. The effectiveness of the proposed RPL protocol is evaluated using IEEE 802.15.4 standard that is applied over OMNeT++ simulator. Finally, the simulation shows promising results of proposed RPL in terms of end-to-end delay, energy, hop count, packet delivery ratio and packet loss rate.

Authors: Méndez-Puga Ana María , Vargas-Silva Alethia Dánae
Published: January 2023

This text presents the results of a research that sought to know the interaction mechanisms that childhood generates to learn from the school and the city, including their participation in their community and in the commercial activities that they develop with their family. We work from an ethnographic research process with Nahua girls and boys from the state of Guerrero, migrants in Morelia, Michoacán, Mexico. We develop two summer courses with different socio-educational and reflection activities, based on reading, writing, sciences experiments, guided visits to a museums, construction of mental cartographies and interviews, from there it was sought to reflect with them and their experiences around the way in which they “appropriate” the city, their community and their school. The results show the ways in which they are interacting with different groups of people in the different spaces. It was also found that in most cases, girls and boys are learning school content not without certain difficulties to continue their schooling, to recognize and appropriate the spaces they interact. But we underline the ways they “reterritorialize” the practices of their families, update cultural practices and strengthen the recognition of Nahuatl self-ascription, influencing this process in other non-Nahua boys and girls and their families, when the conditions of interactions let it.
Risk factor and perinatal outcome in umbilical cord prolapse
Authors: Borthakur Pratyusha , Munisamaih Munikrishna
Published: January 2023

Background: This study is done to determine the risk factors and the perinatal outcomes in umbilical cord prolapse in a tertiary care centre. Umbilical cord prolapse is an utmost obstetrical emergency, which requires prompt intervention to have a good perinatal outcome. Identification of umbilical cord prolapse is of utmost important. Due to exposure of the cord to the external environment, the vessels undergo spasm, which leads to fetal compromise. Delivery of the baby either via caesarean section or vaginal delivery is required immediately following diagnosis. The goal of the current study is to identify the risk factor and also to see the perinatal outcome of umbilical cord prolapse in a tertiary care centre.
Methods: It is a retrospective study conducted in R. L. Jalappa hospital, Kolar from June 2021 to June 2022. Out of 2570 deliveries at our facility throughout the study period, 45 cases were that of umbilical cord prolapse, who were chosen for this study. Both singleton and twin pregnancies were considered. Women below 28 weeks of gestation was not included in the study.
Results: In this study, 45 patients were evaluated who had come with umbilical cord prolapse. It was seen that umbilical cord prolapse occurred in women of multiparity, 36% of the total study population. It was more commonly seen in fetuses weighing 1.5-3 kg, at term (93.3%). Babies that were delivered within 10 minutes of the diagnosis of umbilical cord prolapse has a survival rate of 100%. Whereas the babies delivered after 30 minutes of the diagnosis of cord prolapse did not survive.
Conclusions: Umbilical cord prolapse is associated with increased perinatal morbidity, especially if diagnosed late.

Published: January 2023

: Antimicrobial agent are the biggest contribution to 20th century, which are used to prevent and cure of the infections. Over use of antimicrobials has facilitated the development of resistance. Drug utilization research help in identification of clinical use of drugs in populations and its impact on healthcare system.

: The aim of the study is to identify the overuse/misuse of the antibiotic usage in our intensive care unit. which helps in rationalising the antibiotic prescription and to avoid emergence of drug resistance and to improve better patient’s outcome.

An observational audit has been conducted in inpatient admitted in our set up and has been prescribed with restricted antimicrobials. The audit has been done for 3 months.

The Audit report for 218 patients have been prescribed with Restricted antimicrobials either one or more than one. The audit report shows that Meropenem and Colistin was prescribed more often 81 and 73 respectively. Geriatric Patients have been prrscribed more with Antimicrobials than other age groups. 193 patients were on single Restricted antimicrobial therapy, 24 patients were on dual restricted antimicrobial therapy and one patient was on more than 2 Restricted antimicrobial therapy. Out of 218 Prescription having Restricted Antibiotics, 39 prescription were found irrational.

A wide spectrum of clinical diagnoses and a variety of drugs were utilized from various antibiotic classes. Results showed that Carbapenems(Meropenem) antibiotics were extensively used in ICU. Among Colistin and Vancomycin was most commonly prescribed. Policy for rational usage of restricted antimicrobial agents in ICU should be implemented and education needs to be provided.
Wage determination, Global Value Chains and role played by wage bargaining schemes: The case of Poland
Authors: Nikulin Dagmara , Wolszczak-Derlacz Joanna
Published: January 2023

This study examines the linkages between GVC involvement and wages in Poland given different wage bargaining schemes. The analysis is based on microdata from the European Structure of Earnings Survey for Poland combined with sectoral data from the World Input-Output Database. In particular, two measures of GVC involvement were used: the share of foreign value added (FVA) to export and the measure of traditional offshoring. The institutional settings are represented by the wage bargaining scheme which reflects the level at which the collective pay is agreed. The results show that despite the lack of a significant relationship between the sectoral involvement in GVC and the level of wages in Poland, on average workers covered by the collective pay agreement receive higher wages. Moreover, the wage-GVC nexus is conditioned on the type of pay agreements: the positive wage effect from national agreements is eliminated for a certain range of GVC intensity.

Published: January 2023

Z napredkom novih tehnologij in novih medijev postajajo spletne platforme znanja čedalje pomembnejše tudi v turističnem sektorju. Organizacije za upravljanje destinacij (t. i. DMO-ji), muzeji in druge kulturne ustanove z njihovo uporabo iščejo po eni strani nove načine predstavitve destinacij in produktov, po drugi strani pa predstavljajo nesnovno kulturno dediščino lokalnih prebivalcev in razširjajo znanje o njej, preden se izgubi. Spletne platforme 2.0 so lahko zelo praktična orodja ne le za izmenjavo specifičnega znanja, ampak tudi za načrtovanje mobilnosti. Eno od možnosti ustvarjanja vsebin za spletne platforme predstavlja dejavno vključevanje raziskovanja in literarnega potopisnega pripovedništva v nastajanje vsebin. Poglavje raziskuje ustvarjanje spletnih vsebin skozi literarno potopisno pisanje za nove javnosti in hkrati vrednoti brezplačno dostopna orodja spleta 2.0 za poučevanje in urejanje potopisnih raziskav med terenskim delom na daljavo.

Authors: Zupan Korže Saša
Published: January 2023

Turistične nastanitve (TN) spadajo med temeljne infrastrukturne elemente sekundarne ponudbe v turistični destinaciji (TD). Na njihov fizični izgled, obseg storitev in kakovost vplivajo geografske, socialne, gradbene in ekonomske posebnosti geografskega območja oziroma TD, v katerem se nahajajo. Zaradi navedenih razlik je razumevanje njihove kakovosti težko poenotiti, še težje pa postaviti turistovo doživetje destinacije na isti imenovalec. Namen prispevka je predstaviti, kako lahko razumemo kakovost TN in kako jo presojamo. Izhajamo iz splošnih razsežnosti kakovosti v turizmu in kakovostne TD, ki jih prenesemo v sektor TN, ter iz posebnih standardov kakovosti, oblikovanih izključno za TN. Za boljše razumevanje TN najprej predstavimo njihovo heterogenost in nekatere razvojne smernice v tem podsektorju turizma, ki sooblikujejo njihov razvoj (npr. nove oblike TN, vpliv tehnologije na doživetje v TN, trend trajnostnega poslovanja). Študija potrjuje, da kakovostni standardi TN predstavljajo pomembno trženjsko orodje ne le za posamezno TN, temveč tudi za TD, ki s pomočjo kakovosti TN promovira kakovost destinacije kot celote.

Published: January 2023

Povezovanje športa in turizma predstavlja pomembno smer v razvoju sodobnega turizma. Športni turizem je s tem tudi pomemben člen razvoja slovenskega turizma, znotraj katerega igra pomembno vlogo aktivni turizem v naravi, v katerega lahko štejemo dejavnosti kot so smučanje in druge zimske aktivnosti, kolesarstvo, vodne aktivnosti, adrenalinska doživetja, aktivnosti v zraku in pohodništvo. Pohodništvo, ki predstavlja eno izmed najbolj množičnih aktivnosti v naravi, je v veliki meri razvito na območju Alp in s tem tudi Slovenije. V prispevku je opisan zgodovinski razvoj pohodništva ter vzpostavljanja planinske organizacije na slovenskem. Predstavljena je trenutna krovna organizacija na področju gorništva v Sloveniji z vključeno statistiko gibanja števila članov v preteklih letih in opisom povezovanja s planinskimi organizacijami v Evropi. Ugotavljamo, da pohodništvo spada med najbolj priljubljene in dostopne športne vsebine in predstavlja pomemben element športnega turizma, še posebej aktivnega turizma v naravi. Pohodniški turizem predstavlja pomemben element v razvoju trajnostne in dostopne turistične ponudbe, ki obenem služi tudi kot spodbuda zdravemu načinu življenja tako turistov kot lokalnega prebivalstva.

Gastronomska doživetja in vinske destinacije: razvito podeželje
Authors: Petek Vita , Polak Mojca
Published: January 2023

Slovenska gastronomija s prepoznanimi jedmi znotraj 24 gastronomskih regij vzpostavlja izvirno platformo za ustvarjanje gastronomskih doživetij. Slovenija je vinska dežela, ki se deli na tri vinorodne dežele in devet vinorodnih okolišev. Vsak od njih je prepoznaven po značilnostih, kot so terroir, prst in vremenske razmere, ter karakteristikah vin, ki jih lahko pridelamo na tem območju. V vseh treh vinorodnih deželah najdemo kulinarične prireditve in festivale, povezane z vinom, vinske ceste in fontane ter posebnosti vinskega turizma, ki so značilne samo za določen vinorodni okoliš. Za učinkovito trženje gastronomskih in vinskih doživetij je treba zgodaj prepoznati in implementirati globalne trende ter ustvariti pogoje za trajnostni preplet naravnih in kulturnih danosti.
Mreženje: zagotavljanje dodane vrednosti destinacije
Authors: Lešnik Štuhec Tanja
Published: January 2023

Trajnostni in odgovorni turizem sta vsestranska instrumenta dolgoročnega razvoja. Temeljita na proaktivnem načrtovanju in celovitem upravljanju turističnih vrednostnih verig v zeleni pametni destinaciji. Kakovostna celostna ponudba medsektorsko povezanih pristnih butičnih doživetij ter njena učinkovita in ciljana promocija, trženje in prodaja vplivajo na motivacijo, interes in rast turističnega povpraševanja in potrošnje. Večja potrošnja je povezana z večjim prihodkom destinacije in s povečanjem deleža lokalno oziroma regionalno dodane vrednosti po celoviti verigi turistične ponudbe. Pristop zahteva širok nabor razvojnega interveniranja skozi raznotere projekte povezanih deležnikov, kar sledi strateško načrtovani sliki prihodnosti od spodaj navzgor in od zgodaj navzdol. Mreženje v procesu ustvarjanja vrednosti za oblikovanje, trženje, prodajo in evalviranje avtentičnih zelenih doživetij ima izjemne sinergične in multiplikativne učinke ter moč razpršitve prihodka. S tem se dodaja vrednost po celotni verigi, tudi izven turistične dejavnosti. Tako nastajajo turistični produkti – vodena doživetja, ki certificirana s teritorialnimi kolektivnimi blagovnimi znamkami, vzpostavljenimi po modelu Izvorno slovensko, zagotavljajo visoko kakovost in dodano vrednost destinacije.

Published: January 2023

V prispevku obravnavamo vprašanje organiziranosti turističnega sistema v luči načrtovanja turizma in upravljanja destinacije. Z vidika teorije vključevanja deležnikov turistično destinacijo razumemo kot kompleksen sistem, znotraj katerega deluje množica različnih akterjev, z raznolikimi interesi, atributi in močjo, ki za učinkovito delovanje destinacije usklajujejo svoje interese in se pogajajo za končne dogovore. Kompleksnost turističnega sistema narekuje sistemsko organiziranost na več ravneh, pri čemer je pomembno komunikacijo zagotavljati v horizontalni in tudi v vertikalni smeri. V prispevku pokažemo proces razvoja aktualne organiziranosti celostnega turističnega sistema na ravni destinacije Slovenije skozi strateške odločitve na področju turizma in kritično ovrednotimo trenutno stanje. Na podlagi primerov dobrih praks podamo izhodišča za nadaljnje razmisleke o konsolidaciji organiziranosti slovenskega turističnega sistema.
\(n\)-Fold Filters of EQ-Algebras
Authors: Ganji Saffar Batoul , Kologani Mona Aly , Borzooei Rajab Ali
Published: January 2023

In this paper, we apply the notion of \(n\)-fold filters to the \(EQ\)-algebras and introduce the concepts of \(n\)-fold pseudo implicative, \(n\)-fold implicative, \(n\)-fold obstinate, \(n\)-fold fantastic prefilters and filters on an \(EQ\)-algebra \(\mathcal{E}\). Then we investigate some properties and relations among them. We prove that the quotient algebra \(\mathcal{E}/F\) modulo an 1-fold pseudo implicative filter of an \(EQ\)-algebra \(\mathcal{E}\) is a good \(EQ\)-algebra and the quotient algebra \(\mathcal{E}/F\) modulo an 1-fold fantastic filter of a good \(EQ\)-algebra \(\mathcal{E}\) is an \(IEQ\)-algebra.
A Logic for Dually Hemimorphic Semi-Heyting Algebras and its Axiomatic Extensions
Authors: Cornejo Juan Manuel , Sankappanavar Hanamantagouda P.
Published: January 2023

The variety \(\mathbb{DHMSH}\) of dually hemimorphic semi-Heyting algebras was introduced in 2011 by the second author as an expansion of semi-Heyting algebras by a dual hemimorphism. In this paper, we focus on the variety \(\mathbb{DHMSH}\) from a logical point of view. The paper presents an extensive investigation of the logic corresponding to the variety of dually hemimorphic semi-Heyting algebras and of its axiomatic extensions, along with an equally extensive universal algebraic study of their corresponding algebraic semantics. Firstly, we present a Hilbert-style axiomatization of a new logic called "Dually hemimorphic semi-Heyting logic" (\(\mathcal{DHMSH}\), for short), as an expansion of semi-intuitionistic logic \(\mathcal{SI}\) (also called \(\mathcal{SH}\)) introduced by the first author by adding a weak negation (to be interpreted as a dual hemimorphism). We then prove that it is implicative in the sense of Rasiowa and that it is complete with respect to the variety \(\mathbb{DHMSH}\). It is deduced that the logic \(\mathcal{DHMSH}\) is algebraizable in the sense of Blok and Pigozzi, with the variety \(\mathbb{DHMSH}\) as its equivalent algebraic semantics and that the lattice of axiomatic extensions of \(\mathcal{DHMSH}\) is dually isomorphic to the lattice of subvarieties of \(\mathbb{DHMSH}\). A new axiomatization for Moisil's logic is also obtained. Secondly, we characterize the axiomatic extensions of \(\mathcal{DHMSH}\) in which the "Deduction Theorem" holds. Thirdly, we present several new logics, extending the logic \(\mathcal{DHMSH}\), corresponding to several important subvarieties of the variety \(\mathbb{DHMSH}\). These include logics corresponding to the varieties generated by two-element, three-element and some four-element dually quasi-De Morgan semi-Heyting algebras, as well as a new axiomatization for the 3-valued Łukasiewicz logic. Surprisingly, many of these logics turn out to be connexive logics, only a few of which are presented in this paper. Fourthly, we present axiomatizations for two infinite sequences of logics namely, De Morgan Gödel logics and dually pseudocomplemented Gödel logics. Fifthly, axiomatizations are also provided for logics corresponding to many subvarieties of regular dually quasi-De Morgan Stone semi-Heyting algebras, of regular De Morgan semi-Heyting algebras of level 1, and of JI-distributive semi-Heyting algebras of level 1. We conclude the paper with some open problems. Most of the logics considered in this paper are discriminator logics in the sense that they correspond to discriminator varieties. Some of them, just like the classical logic, are even primal in the sense that their corresponding varieties are generated by primal algebras.
The influence of translingualism on the establishment of language worldview: Case study of color term associations
Authors:   Peoples’ Friendship University of Russia, Novikova Marina L. , Novikov Phillip N.
Published: January 2023

The research focuses on the influence of translingualism on the establishment of language worldview. Due to the relevance of the problem, the article sets the task to investigate the influence of translingualism on the formation of the language worldview as a process of perceiving the environment through its color components through the prism of speakers of different languages. Based on the observation of translingual connections that arise between linguistic and color stimuli, the key idea is illustrated that a number of patterns that manifest themselves in the interaction between native and foreign languages indicate that the diversity of languages creates different mental angles and projections of color term awareness. This study is based on the results of an experiment conducted among speakers of 15 different languages. This perspective of the study allows us to substantiate that awareness and perception of color terms in different languages reflect the complementarity of language processes, their dynamism, deep qualitative and quantitative features. The language worldview is a reflection of the objective color spectrum in its specific interpretation and is characteristic of representatives of different cultures. It fixes the features of its perception and the specifics of language associations, indicates that they have acquired new semantic connections and leads to creation of new meanings.
Translation as a form of representation of the cultural boundaries
Authors:   Kazan (Volga Region) Federal University, Amineva Venera R. ,   Gorky Institute of World Literature of the Russian Academy of Sciences
Published: January 2023

Based on the material of the translation of poems of Tatar poets of the 60s, made by R. Kozhevnikova, the features of the representation of hybrid identity, which is carried out both “within”, “inside” homogeneous culture, and “on the boundaries”, “between” different traditions are studied. Unlike other Russian-speaking poets-translators such as R. Bukharaev, who is painfully experiencing a crisis of his identity, R. Kozhevnikova feels an organic involvement in the traditions of both Tatar and Russian cultures. It is concluded that in R. Kozhevnikova’s lyrics and in her translations of Tatar poetry, there is a synthetizing tendency focused on overcoming the boundaries between different historical and cultural meanings. But unlike the original works, which have specific accentuation and actualize ordinary relations between the word and the reality defined by it, in translated texts there are not identical value and semantic horizons. The means of clarifying the original text used by the translator as a form of inter-literary dialogue are described. It is stated that the transformation of an “alien” verbal and artistic practice in a “different” / “own” in the translation process is followed by the strengthening of the emotional and suggestive component of the text, its musical and sound, rhythmic and intonational instrumentation carried out by means of the Russian language, the development of subjective situation which makes the basis of the work, identification with the genres familiar to the Russian-speaking reader.
Armenian text: Poetry and prose
Authors:   Moscow City Pedagogical University, Shafranskaya Eleonora F.
Published: January 2023

The article continues the analysis of the Armenian text — the phenomenon of Russian culture and literature, which we presented in the previous article “The Armenian text: the Children of Job” (Polylinguality and Transcultural Practices. 2022. No. 3). The algorithm for analyzing the Armenian text is presented on the basis of prose texts of the last third of the 20th century (and a dotted line of the 21st), as well as poetic texts of modern poets (Liana Shahverdyan, Maxim Amelin, Alessio Gaspari, Georgy Kubatyan). The article examines the patterns associated with the key names, attributes and space of the Armenian picture of the world — as it develops in Russian literary reception. These are such patterns as Ararat, Sevan, sea, lavash, Armenian patio. Hrant Matevosyan. We offer a new pattern of the Armenian text — the personality and creativity of G. Kubatyan. The study is an attempt to oppose the Armenian text to a simple mention of Armenian attributes in literature. The author also offers an indispensable “ingredient” for the emergence of a local text as such, in particular, an Armenian one. The hierarchy between verses and prose in the process of the birth of a local text is indicated, albeit controversial.

AbstractIntroduction: Some native plants in Indonesia have potential effects on health and medication. This study aimed to determine the potential antibacterial effect of Averrhoa bilimbi (A. bilimbi) leaves ethanol extract against Salmonella typhi (S. typhi) bacteria. Methods: This was an experimental study. The antibacterial potency of A. bilimbi leaves was measured against S. typhi in vitro. Different concentrations of the leaves’ ethanol extract were prepared. The minimum inhibitory concentration (MIC) was evaluated by a macro-dilution method using Mueller Hinton broth. The minimum bactericidal concentration (MBC) value was observed by subculturing the specimen from the previous dilution tube to the nutrient agar.Results: The MIC of A. bilimbi leaves ethanol extract against S. typhi bacteria could not be determined because all the treatment tubes’ colors were dark and turbid. Meanwhile, the MBC value was at 500 mg/ml.Conclusion: A. bilimbi leaves extract had potential bactericidal effects against S. typhi with a MIC value that could not be determined.

The emergence of unmanned aerial vehicles (UAVs) raised multiple concerns, given their potential for malicious misuse in unlawful acts Vision-based counter-UAV applications offer a reliable solution compared to acoustic and radio frequency-based solutions because of their high detection accuracy in diverse weather conditions. The existing solutions work well on trained datasets, but their accuracy is relatively low for real-time detection. In this paper, we model deep learning-empowered solutions to improve the multi-class UAV's classification performance using single-shot object detection algorithms YOLOv5 and YOLOv7. The transfer learning is employed for performance improvement and rapid training with improved results. We customized a multi-class dataset containing multi-rotor, fixed-wing, and single-rotor UAVs in challenging weather conditions. Experiments show that the integration of transfer learning has achieved good results, with an overall best average-classification precision of 94\%, an average recall of 93.1\%, a mAP$@$0.5 average of 95.3\%, and an average F1 score of 92.33\%.

Pauli’s Electron in Ehrenfest and Bohm Theories, a Comparative Study
Authors: Yahalom Asher
Published: January 2023

Electrons moving at slow speeds much lower that the speed of light are described by a wave function which is a solution of Pauli’s equation. This is a low velocity limit of the relativistic Dirac equation. Here we compare two approaches, one which is the more conservative Copenhagen’s interpretation denying a trajectory of the electron but allowing a trajectory to the electron expectation value through Ehrenfest theorem. The said expectation value is of course calculated using a solution of Pauli’s equation. A less orthodox approach is championed by Bohm, and attributes a velocity field to the electron also derived from the Pauli wave function. It is thus interesting to compare the trajectory followed by the electron according to Bohm and its expectation value according to Ehrenfest. Both similarities and differences will be considered.

The stability and harmony of ecological niches rely on intricated interactions between their members. During evolution, organisms have developed the ability to thrive in different environments taking advantage of each other’s metabolic symphonies. Among them, microalgae are a highly diverse and widely distributed group of major primary producers whose interactions with other organisms play essential roles in their habitats. Understanding the basis of these interactions is crucial to control and exploit these communities for ecological and biotechnological applications. The green microalga Chlamydomonas reinhardtii, a well-established model, is emerging as a model organism for studying a wide variety of microbial interactions with ecological and economic significance. In this review, we bring together and discuss current knowledge that points to C. reinhardtii as a model organism for studying microbial interactions.

Landslide risk mitigation is limited by data scarcity. This could be improved using continuous landslide detection systems. In order to investigate which image types and machine learning (ML) models are most useful for landslide detection in a Norwegian setting, we compared the performance of five different ML models, for the Jølster case study (30-July-2019), in Western Norway. These included three globally pre-trained models; i) the Continuous Change Detection and Classification (CCDC) algorithm, ii) a combined k-means clustering and Random Forest classification model, and iii) a convolutional neural network (CNN), and two locally-trained models, including; iv) Classification and Regression Trees and v) a U-net CNN model. Images used included Sentinel-1, Sentinel-2, digital elevation model (DEM) and slope. The globally-trained models performed poorly in shadowed areas, and were all outperformed by the locally-trained models. A maximum Matthew’s correlation coefficient (MCC) score of 89% was achieved with model v, using combined Sentinel-1 and -2 images as input. This is one of the first attempts to apply deep-learning to detect landslides with both Sentinel-1 and -2 images. Using Sentinel-1 images only, the locally-trained deep-learning model significantly outperformed the conventional ML model. These findings contribute towards developing a national continuous monitoring system for landslides.
Неклассический взгляд на природу значений истинности

Работа посвящена семантике многозначных логик и касается проблемы содержательной интерпретации значений в логических матрицах. Отправной точкой исследования служит тезис Р. Сушко, согласно которому каждая многозначная логика является логически двухзначной, а также анализ этого тезиса в последующей литературе. Как показал Сушко, любая многозначная матричная семантика может быть редуцирована к двум значениями. Это поставило вопрос о том, возможны ли в принципе многозначные логики. Положительный ответ был дан Г. Малиновским на основе предложенной им концепции инференциальной многозначности. Фундамент данной концепции составляют обобщения понятий логической матрицы и отношения следования, где наряду с классом выделенных значений задействованы другие подмножества универсума матрицы, рассматриваемые в качестве логических значений. Это позволяет Малиновскому привести примеры многозначных семантик, которые нельзя редуцировать к двум значениям, используя метод Сушко. Опираясь на результаты Малиновского и других авторов, разрабатывавших данную тему, мы предлагаем собственные обобщения понятий логической матрицы и следования. В качестве логических значений рассматриваются не подмножества универсума матрицы, а отношения, то есть, подмножества декартовых степеней универсума. Такое обобщение делает возможным построение бивалентных инстинносто-функциональных семантик для логик, которые, как вытекает из известных в литературе результатов, не имеют двухзначной семантики в стиле Сушко.

Adeno-associated viruses (AAVs) promise robust gene delivery to the brain through non-invasive, intravenous delivery. However, unlike in rodents, few neurotropic AAVs efficiently cross the blood-brain barrier in non-human primates (NHPs). Here we describe AAV.CAP-Mac, an engineered variant identified by screening in adult marmosets and newborn macaques with improved efficiency in the brain of multiple NHP species: marmoset, rhesus macaque, and green monkey. CAP-Mac is neuron-biased in infant Old World primates, exhibits broad tropism in adult rhesus macaques, and is vasculature-biased in adult marmosets. We demonstrate applications of a single, intravenous dose of CAP-Mac to deliver (1) functional GCaMP for ex vivo calcium imaging across multiple brain areas, and (2) a cocktail of fluorescent reporters for Brainbow-like labeling throughout the macaque brain, circumventing the need for germline manipulations in Old World primates. Given its capabilities for systemic gene transfer in NHPs, CAP-Mac promises to help unlock non-invasive access to the brain.

Background: Ulnar impaction syndrome caused by positive ulnar variance often requires ulnar shortening osteotomy (USO) to unload the ulnocarpal joint. The therapeutic effect of USO in treatment of ulnar impaction syndrome is limited due to complications such as hardware irritation, non-union rotation and angulation. Despite various devices have been introduced to overcome these limitations, more accurate and simple devices are still needed. The purpose of this study was to introduce a novel method of the ortho-bridge fixation system combined with 3D-printed guide plate to achieve precise ulnar shortening osteotomy with less complications simply.
Methods: This was a retrospective study comprising nine patients with ulnar impaction syndrome who underwent ulnar shortening osteotomy by this method. The CT scan data of patients were retrieved for printing the osteotomy guide plate. The ortho-bridge system served as ulnar shortening and internal fixation. The outcome measurements included the time to union, complications, range of motion, grip strength and wrist pain.
Results: The ulna was shortened successfully in all of the nine cases without rotation and angulation. Non-union was not observed in any of the cases during follow-up between 12 months after surgery. The range of motion, grip strength and wrist pain also improved following surgery (p<0.05).
Conclusion: The ortho-bridge internal fixation system combined with 3D-printed osteotomy guide effectively simplified the procedure, and restored ulnar variance without rotation, angulation and non-union. It is a reliable method for treating ulnocarpal impaction syndrome through ulnar shortening osteotomy.
Cooling Oceans Did Trigger Ordovician Biodiversification

Global cooling during the Ordovician (485 Ma to 443 Ma) has long been considered as a possible driver of the Great Ordovician Biodiversification Event (GOBE), the largest radiation of Phanerozoic marine animal Life. Yet, this hypothesis exclusively relies on temporal correlations. Mechanistic understanding of the underlying pathways is lacking and other possible causes are debated. Here we couple an ocean-atmosphere general circulation model with a macroecological model to reconstruct global biodiversity patterns from 490 Ma to 430 Ma. Our results demonstrate that the GOBE permitted the development of a Modern-like Latitudinal Biodiversity Gradient (LBG). Inverted LBGs, with biodiversity increasing from the equator to the poles, characterize the late Cambrian and Early Ordovician when climate was much warmer than today. A Modern LBG develops in the Mid-Late Ordovician in response to the drop in ocean temperatures. Globally, simulated biodiversity increases due to long-term cooling during the Ordovician. This increase is a consequence of the ecophysiological limitations to marine Life and is robust to uncertainties in both proxy-derived temperature reconstructions and organism physiology. First-order model-data agreement suggests that the most conspicuous rise in biodiversity over Earth’s history –GOBE– was primarily driven by global cooling.
Structural basis for negative regulation of the Escherichia coli maltose system

Published: January 2023

Proteins from the signal transduction ATPases with numerous domains (STAND) family are known to play an important role in innate immunity. However, it remains less well understood how they function in transcriptional regulation. MalT is a bacterial STAND that controls the Escherichia coli maltose system. Inactive MalT is sequestered by different inhibitory proteins such as MalY. Here, we show that MalY interacts with one oligomerization interface of MalT to form a 2:2 complex. MalY represses MalT activity by blocking its oligomerization and strengthening ADP-mediated MalT autoinhibition. A loop region N-terminal to the nucleotide-binding domain (NBD) of MalT has a dual role in mediating MalT autoinhibition and activation. Structural comparison shows that ligand-binding induced oligomerization is required for stabilizing the C-terminal domains and conferring DNA-binding activity. Together, our study reveals the mechanism whereby a prokaryotic STAND is inhibited by a repressor protein, and offers insights into signaling by STAND transcription activators.
