Published: August 2023

Terrible environmental conditions on Earth have warned us over the past decade. To avoid the current situation going further, many countries started to implement sustainable green building development. Sustainable green building development tends to preserve and conserve the environment by using sustainable green material, decrease of negative impact from construction industry and improve on the building life cost cycle. Although the number of green buildings increased compared to last century, but adoption of sustainable green building in the Malaysian construction industry is considered slow. Besides, sustainable green building development also concerns social and economic aspects. This study will analyze the current status of green building development in Malaysia. The study has reviewed articles pertinent to green building development from reputable science databases. The result obtained showed the current status of green building development is decreasing due to the impact of Pandemic COVID-19. Furthermore, the results also showed the number of green buildings in Malaysia is comparatively low. This study provided a benchmark for policy makers and construction key stakeholders about the current status of green building development in Malaysia which can be utilized as a guideline in promoting green building development.

From Language Learning Media to Representing Turkish Culture: Cultural Content in Turkish Language Textbooks
Authors: Mualimin Mualimin , Fathiyakan Fathiyakan , Rahayu Siti
Published: August 2023

Language has a close relationship with culture, so that language learning often uses cultural content as a learning medium. Therefore this study aims to analyze the cultural content in textbooks for learning Turkish and its relation as a medium of learning between Turkish languages. This study is qualitative research with a literature study approach. The source of the data in this study was the textbook for learning Turkish, namely "Istanbul Yabancılar İçin Türkçe Ders Kitabı". Data were collected by observing the content in the book. The data obtained were then analyzed using the Miles and Huberman qualitative analysis model: data reduction, data display, and conclusion. The findings in this study lead to the conclusion that cultural content is a crucial and inseparable part of the substance of the book "Istanbul Yabancılar İçin Türkçe Ders Kitabı" as a Turkish language textbook. At this level, the cultural content has two functions at once: bridging understanding related to Turkish grammar and representing the cultural identity of the Turkish people to international students.

We measure the Einstein radius of the single-lens microlensing event KMT-2022-BLG-2397 to be θ
E = 24.8 ± 3.6 μas, placing it at the upper shore of the Einstein Desert, 9 ≲ θ
E/μas ≲ 25, between free-floating planets (FFPs) and bulge brown dwarfs (BDs). In contrast to the six BD (25 ≲ θ
E ≲ 50) events presented by Gould et al. (2022), which all had giant-star source stars, KMT-2022-BLG-2397 has a dwarf-star source, with angular radius θ
ast ∼ 0.9 μas. This prompts us to study the relative utility of dwarf and giant sources for characterizing FFPs and BDs from finite-source point-lens (FSPL) microlensing events. We find “dwarfs” (including main-sequence stars and subgiants) are likely to yield twice as many θ
E measurements for BDs and a comparable (but more difficult to quantify) improvement for FFPs. We show that neither current nor planned experiments will yield complete mass measurements of isolated bulge BDs, nor will any other planned experiment yield as many θ
E measurements for these objects as the Korea Microlensing Telescope (KMT). Thus, the currently anticipated 10 yr KMT survey will remain the best way to study bulge BDs for several decades to come.
Rapid Quenching of Galaxies at Cosmic Noon

Published: August 2023

The existence of massive quiescent galaxies at high redshift seems to require rapid quenching, but it is unclear whether all quiescent galaxies have gone through this phase and what physical mechanisms are involved. To study rapid quenching, we use rest-frame colors to select 12 young quiescent galaxies at z ∼ 1.5. From spectral energy distribution fitting, we find that they all experienced intense starbursts prior to rapid quenching. We confirm this with deep Magellan/FIRE spectroscopic observations for a subset of seven galaxies. Broad emission lines are detected for two galaxies, and are most likely caused by active galactic nucleus (AGN) activity. The other five galaxies do not show any emission features, suggesting that gas has already been removed or depleted. Most of the rapidly quenched galaxies are more compact than normal quiescent galaxies, providing evidence for a central starburst in the recent past. We estimate an average transition time of 300 Myr for the rapid quenching phase. Approximately 4% of quiescent galaxies at z = 1.5 have gone through rapid quenching; this fraction increases to 23% at z = 2.2. We identify analogs in the TNG100 simulation and find that rapid quenching for these galaxies is driven by AGNs, and for half of the cases, gas-rich major mergers seem to trigger the starburst. We conclude that these young massive quiescent galaxies are not just rapidly quenched, but also rapidly formed through a major starburst. We speculate that mergers drive gas inflow toward the central regions and grow supermassive black holes, leading to rapid quenching by AGN feedback.
Differences between the Pierre Auger Observatory and Telescope Array Spectra: Systematic Effects or Indication of a Local Source of Ultra-high-energy Cosmic Rays?
Authors: Plotko Pavlo , van Vliet Arjen , Rodrigues Xavier , Winter Walter
Published: August 2023

The Pierre Auger Observatory (PAO) and Telescope Array (TA) collaborations report significant differences in the observed energy spectra of ultra-high-energy cosmic rays (UHECRs) above 30 EeV. In this work we present a joint fit of TA and PAO data using the rigidity-dependent maximum energy model, including a full marginalization over all relevant parameters. We test two possible scenarios to explain these differences. One is that they are due to complex energy-dependent experimental systematics; the other is the presence of a local astrophysical source in the Northern Hemisphere, which is only visible by the TA experiment. We show that the astrophysical and systematic scenarios improve the explanation of the data equally well, compared to the scenario where both experiments observe the same UHECR flux from a cosmological source distribution and have energy-independent systematics. We test different mass compositions emitted from the local source and conclude that the data are best described by a source lying at a distance below 26 Mpc that emits cosmic rays dominated by the silicon mass group. We also discuss possible source candidates and the possible role of the putative local UHECR source in the observed TA anisotropy and in the differences in TA spectral data from different decl. bands.
The Magnetic Fields of Starburst Galaxies. I. Identification and Characterization of the Thermal Polarization in the Galactic Disk and Outflow
Authors: Lopez-Rodriguez Enrique
Published: August 2023

Far-infrared polarized emission by means of magnetically aligned dust grains is an excellent tracer of the magnetic fields (B-fields) in the cold phase of the galactic outflows of starburst galaxies. We present a comprehensive study of the B-fields in three nearby (3.5–17.2 Mpc) starbursts (M82, NGC 253, and NGC 2146) at 5 pc–1.5 kpc resolutions using publicly available 53–890 μm imaging polarimetric observations with Stratospheric Observatory for Infrared Astronomy/HAWC+, James Clerk Maxwell Telescope/POL-2, and ALMA. We find that the polarized spectral energy distributions (SEDs) of the full galaxies are dominated by the polarized SEDs of the outflows with dust temperatures of

. We show that disk- and outflow-dominated galaxies can be better distinguished by using polarized SEDs instead of total SEDs. We compute the 53–850 μm polarization spectrum of the disk and outflow, and find that dust models of the diffuse ISM can reproduce the fairly constant polarization spectrum of the disk, 〈 P
disk〉 = 1.2% ± 0.5%. The dust models of heterogenous clouds and two-temperature components are required to explain the polarization spectrum of the outflow (2%–4% at 53 μm, ∼1% at 850 μm, and a minimum within 89–154 μm). We conclude that the polarized dust grains in the outflow arise from a dust population with higher dust temperature and emissivities than those from the total flux. The B-fields of the outflows have maximum extensions within 89–214 μm reaching heights of ∼4 kpc, and have flatter polarized fluxes than total fluxes. The extension of the B-field permeating the circumgalactic medium increases as the star formation rate increases.
Reprocessing Models for the Optical Light Curves of Hypervariable Quasars from the Sloan Digital Sky Survey Reverberation Mapping Project

Published: August 2023

We explore reprocessing models for a sample of 17 hypervariable quasars, taken from the Sloan Digital Sky Survey Reverberation Mapping project, which all show coordinated optical luminosity hypervariability with amplitudes of factors ≳2 between 2014 and 2020. We develop and apply reprocessing models for quasar light curves in simple geometries that are likely to be representative of quasar inner environments. In addition to the commonly investigated thin-disk model, we include the thick-disk and hemisphere geometries. The thick-disk geometry could, for instance, represent a magnetically elevated disk, whereas the hemisphere model can be interpreted as a first-order approximation for any optically thick out-of-plane material caused by outflows/winds, warped/tilted disks, and so on. Of the 17 quasars in our sample, 11 are best-fitted by a hemisphere geometry, five are classified as thick disks, and both models fail for just one object. We highlight the successes and shortcomings of our thermal reprocessing models in case studies of four quasars that are representative of the sample. While reprocessing is unlikely to explain all of the variability that we observe in quasars, we present our classification scheme as a starting point for revealing the likely geometries of reprocessing for quasars in our sample and hypervariable quasars in general.
Sequential Small Coronal Mass Ejections Observed In Situ and in White-Light Images by Parker Solar Probe
Authors: Wood Brian E. , Hess Phillip , Chen Yu , Hu Qiang
Published: August 2023

We reconstruct the morphology and kinematics of a series of small transients that erupted from the Sun on 2021 April 24 using observations primarily from Parker Solar Probe (PSP). These sequential small coronal mass ejections (CMEs) may be the product of a continuous reconnection at a current sheet, which is a macroscopic example of the more microscopic reconnection activity that has been proposed to accelerate the solar wind more generally. These particular CMEs are of interest because they are the first CMEs to hit PSP and be simultaneously imaged by it, using the Wide-field Imager for Solar Probe (WISPR) instrument. Based on imaging from WISPR and STEREO-A, we identify and model six discrete transients, and determine that it is the second of them (CME2) that first hits PSP, although PSP later more obliquely also encounters the third transient. Signatures of these encounters are seen in the PSP in situ data. Within these data, we identify six candidate magnetic flux ropes (MFRs), all but one of which are associated with the second transient. The five CME2 MFRs have orientations that are roughly consistent with PSP encountering the right-hand sides of roughly E-W oriented MFRs, which are sloping back toward the Sun.
Mass Distribution for Single-lined Hot Subdwarf Stars in LAMOST

Published: August 2023

Masses for 664 single-lined hot subdwarf stars identified in LAMOST were calculated by comparing synthetic fluxes from spectral energy distribution with observed fluxes from a Virtual Observatory service. Three groups of hot subdwarf stars were selected from the whole sample according to their parallax precision to study the mass distributions. We found that He-poor sdB/sdOB stars present a wide mass distribution from 0.1 to 1.0 M
⊙ with a sharp mass peak at around 0.46 M
⊙, which is consistent with canonical binary model prediction. He-rich sdB/sdOB/sdO stars present a much flatter mass distribution than He-poor sdB/sdOB stars and with a mass peak at around 0.42 M
⊙. By comparing the observed mass distributions to the predictions of different formation scenarios, we concluded that the binary merger channel, including two helium white dwarfs (He-WDs) and He-WD + main-sequence mergers, cannot be the only main formation channel for He-rich hot subdwarfs, and other formation channels, such as the surviving companions from Type Ia supernovae, could also make impacts on producing this special population, especially for He-rich hot subdwarfs with masses less than 0.44 M
⊙. He-poor sdO stars also present a flatter mass distribution with an inconspicuous peak mass at 0.18 M
⊙. The similar mass–

distribution between He-poor sdB/sdOB and sdO stars supports the scenario that He-poor sdO stars could be the subsequent evolution stage of He-poor sdB/sdOB stars.
Modeling Solids in Nuclear Astrophysics with Smoothed Particle Hydrodynamics

Published: August 2023

Smoothed particle hydrodynamics (SPH) is a frequently applied tool in computational astrophysics to solve the fluid dynamics equations governing the systems under study. For some problems, for example when involving asteroids and asteroid impacts, the additional inclusion of material strength is necessary in order to accurately describe the dynamics. In compact stars, that is white dwarfs and neutron stars, solid components are also present. Neutron stars have a solid crust, which is the strongest material known in nature. However, their dynamical evolution, when modeled via SPH or other computational fluid dynamics codes, is usually described as a purely fluid dynamics problem. Here, we present the first 3D simulations of neutron star crustal toroidal oscillations including material strength with the Los Alamos National Laboratory SPH code FleCSPH. In the first half of the paper, we present the numerical implementation of solid material modeling together with standard tests. The second half is on the simulation of crustal oscillations in the fundamental toroidal mode. Here, we dedicate a large fraction of the paper to approaches that can suppress numerical noise in the solid. If not minimized, the latter can dominate the crustal motion in the simulations.
Three-day Forecasting of Solar Wind Speed Using SDO/AIA Extreme-ultraviolet Images by a Deep-learning Model
Authors: Son Jihyeon , Sung Suk-Kyung , Moon Yong-Jae , Lee Harim , Jeong Hyun-Jin
Published: August 2023

In this study, we forecast solar wind speed for the next 3 days with a 6 hr cadence using a deep-learning model. For this we use Solar Dynamics Observatory/Atmospheric Imaging Assembly 211 and 193 Å images together with solar wind speeds for the last 5 days as input data. The total period of the data is from 2010 May to 2020 December. We divide them into a training set (January–August), validation set (September), and test set (October–December), to consider the solar cycle effect. The deep-learning model consists of two networks: a convolutional layer–based network for images and a dense layer–based network for solar wind speeds. Our main results are as follows. First, our model successfully predicts the solar wind speed for the next 3 days. The rms error (RMSE) of our model is from 37.4 km s−1 (for the 6 hr prediction) to 68.2 km s−1 (for the 72 hr prediction), and the correlation coefficient is from 0.92 to 0.67. These results are much better than those of previous studies. Second, the model can predict sudden increase of solar wind speeds caused by large equatorial coronal holes. Third, solar wind speeds predicted by our model are more consistent with observations than those by the Wang–Sheely–Arge–ENLIL model, especially in high-speed-stream regions. It is also noted that our model cannot predict solar wind speed enhancement by coronal mass ejections. Our study demonstrates the effectiveness of deep learning for solar wind speed prediction, with potential applications in space weather forecasting.
Performance of SNP markers for parentage analysis in the Italian Alpine brown bear using non-invasive samples

Published: August 2023

Determination of parentage provides valuable information for the conservation of wild populations, for instance, by allowing the monitoring of breeding success and inbreeding. Between 1999 and 2002, nine brown bears (Ursus arctos) were translocated to augment the remnant population of a few surviving individuals in the Italian Alps, but only part of them reproduced, with a higher inbreeding risk occurrence in the long-time. Currently, in the Alpine population, parentage tests are assessed through the analysis of 15 microsatellite loci (STRs), but the reduction of genetic variability in future generations will need the use of additional informative markers. Single nucleotide polymorphisms (SNPs) have been proven to be useful and reliable in individual identification and family reconstruction; moreover, they can perform well on low-quality samples. In this study, we analysed 51 SNPs to generate a SNP multilocus genotype dataset of 54 Alpine brown bears (Ursus arctos) and compared its performance in parentage analysis with the validated STR dataset. We found that SNPs alone are not sufficient to determine parentage relationships, but the combination of SNPs and STRs provided unambiguous parentage assignments. The combined panel also performed better than STRs when true parents were not present in the dataset and, consequently, showed higher values of assignment probabilities.

Teaching Prelicensure Nursing Students Reasoning in Clinical Experiences: A Pilot Study
Authors: Fontenot Justin , Leigh Gwen , Watson Cynthia , Stueben Frances , Arceneaux Stephanie , Johnson Sharonda , St. Romain Arielle
Published: August 2023

Background:

Clinical experiences are foundational learning components for prelicensure nursing students. Given the complexities of modern nursing practice in an aging America, clinical educators must teach nursing students to reason when engaging in patient care. Contemporary pedagogy to enhance reasoning relies on case studies and simulation. Specific and standardized methods for clinical education are largely absent in the literature.

Method:

This pilot study measured the clinical reasoning ability of nursing students using the Health Sciences Reasoning Test (HSRT). Participants completed the test before their first clinical day and again after their last clinical day. Pre- and posttest HSRT scores were analyzed by control and intervention groups as well as student levels.

Results:

Posttest HSRT scores improved significantly in the intervention group at the end of the semester.

Conclusion:

The PREP framework is a novel approach to clinical education and improved the clinical reasoning of prelicensure nursing students.

Developing trust among players in a vendor-managed inventory model for random demand under environmental impact
Authors: Saren Sharmila , Guchhait Rekha , AlArjani Ali , Sarkar Biswajit
Published: August 2023

Retailers play a vital role in supply chain management because they deal directly with consumers. Occasionally, retailers may cover the entire system's statistics and not disclose these data to the manufacturer. Therefore, asymmetry is generated in the data throughout the system. The main motive of this research was to prevent unreliability throughout the system using a vendor-managed inventory policy. This research shows that by applying a cap and trade policy, the total carbon emitted from the production and transportation sectors can be controlled in the atmosphere. Finally, numerical and sensitivity analyses, along with pictorial representations of various parameters, are performed to examine the optimal results of this study. In addition, the retailer's lead time demand for items is assumed to be random rather than fixed and follows uniform and normal distribution functions. Under these two distribution functions, the optimal retailer lot size, service provided by the retailer to customers, and retailer reorder points are assessed. Furthermore, an evaluation of the total carbon released from an environmental viewpoint is illustrated using numerical findings. The numerical results show that this research is 50.24% more economically beneficial than the methods used in previous studies, whereas the mean value of demand follows a uniform distribution.

Descartesovo stvarjenje sveta: rojstvo genetične epistemologije
Authors: Kroupa Gregor
Published: August 2023

Članek opisuje redko komentirano metodo razlage, ki jo pri Descartesu prvič srečamo v šestem poglavju njegovega posmrtno objavljenega spisa Svet (Le monde), kjer s pomočjo fiktivne kozmologije skuša razložiti zakonitosti dejanskega materialnega univerzuma. Predpostavka tega pristopa je, da je strukturo ali naravo objekta spoznanja najbolje razviti skozi prikaz njegove geneze ali proizvedljivosti, pa čeprav ta ni dejanska, ampak fiktivna, ali bolje, prav zato, ker je fiktivna. Ta Descartesova metoda »genetične epistemologije« pa se izkaže za presenetljivo vplivno: najdemo jo na primer v Rousseaujevih razmišljanjih o naravnem stanju in ne nazadnje tudi v interpretacijah same Descartesove filozofije – pri Martialu Gueroultu in njegovem načelu »reda razlogov«.
Kanon in revolucija: vloga pojma znanstvene revolucije pri vzpostavitvi zgodovine znanosti kot discipline
Authors: Komel Svit
Published: August 2023

Slovensko epistemologijo določa značilen kanon, ki izhaja iz treh temeljnih avtorjev: Gastona Bachelarda, Alexandra Koyréja in Thomasa Kuhna. Naveden kanon združuje drža, da je treba na zgodovino znanosti gledati kot na zgodovino radikalnih prelomov ali revolucij v znanstveni misli. Pomanjkljivost takšnega izbora avtorjev ni le njegova zastarelost, temveč da je znotraj njega težko razbrati probleme, ki jih poraja s tem kanonom utemeljen pristop k zgodovini znanosti. Da bi izpostavil slepe pege slovenske epistemologije, predstavim drugačno recepcijo pojma znanstvene revolucije v Združenem Kraljestvu in ZDA. Metodološki program, ki se osredotoča na revolucionarne prelome v znanstvenih idejah, torej ponovno ovrednotim skozi obravnavo njegove strateške vloge pri institucionalizaciji zgodovine znanosti kot discipline. Dogodek, ki je zaznamoval prevajanje francoske epistemologije v angleško zgodovino znanosti, so bila predavanja delegatov iz Sovjetske zveze na drugem Mednarodnem kongresu za zgodovino znanosti in tehnologije leta 1931. Povojna angloameriška zgodovina znanosti je namreč koncept znanstvene revolucije prevzela kot sredstvo izključevanja marksističnih študij znanosti, kakršne so se razširile pod vplivom sovjetske delegacije, iz polja sprejemljivega diskurza. V članku pokažem, kako je hladnovojno znanstveno zgodovinopisje uvedlo razlikovanje med »notranjimi« in »zunanjimi« dejavniki znanstvenega razvoja, ki naj bi sintezo domnevno doživeli v delu Thomasa Kuhna.

Authors: Šumah Lidija
Published: August 2023

The general question underlying this article is whether it is possible to turn a paradox into a productive principle. The article approaches this question through Adorno’s and Dainotto’s analyses of the jazz movement in fascist Italy. Jazz was marked by a specific paradox: on the one hand, it was banned due to its African American roots, and as such did not adhere to or glorify the Italian tradition; on the other hand, jazz served very well to protect the nationalist interests in the light of the nascent mass movements. Against the backdrop of these analyses, the article proposes two distinct paradigms of exception: the logic of count till all and the logic of count till none.
Emergency Revisited
Authors: Troha Tadej
Published: August 2023

In the first part of the article, the author analyses the last phase of the Covid-19 pandemic, which he terms “ex-communication”. A characteristic of this phase is not only virus”, but also the irrevocable transition to “living with the virus” but also the retroactive erasure of potentially valuable lessons from the pandemic for dealing with other crises. After outlining a new legal understanding of climate emergency in the second part of the text, the author concludes by focusing on the global warming debate in the 1970s. In doing so, he posits that we must search for the origin of all forms of “climate delay” (Lamb et al.) in the confluence of two contradictory tendencies during that period: the determination to stop global warming early and the techno-utopian desire to prevent the onset of an ice age by deliberately warming the atmosphere. The irony is that the caution offered as a way out of the contradiction not only failed to mitigate climate change but ultimately prevented the onset of an ice age for the foreseeable future. Such clear signals of the Anthropocene present us with a new choice, i.e. a choice between two versions of the self-evident, two versions of the impossible.
The Place of the Subject in Badiou’s Theory of Discipline
Authors: Naderi Reza
Published: August 2023

Alain Badiou’s theory of discipline condenses many important theoretical tools that he developed throughout his long encounter with various philosophical and political milieus from the mid 1960s to the mid 1980s, when he wrote his magnum opus Being and Event. Through this vast terrain, Badiou expressed seemingly different commitments: from logic and the epistemology of science in the late 1960s and politics during the 1970s, to ontology and mathematics in the 1980s, which has continued to this time. However, a close reading of his major works during this period reveals an internal thread of thought that runs between them, which I have named discipline. In other words, discipline is the framework within which we can reconstruct Badiou’s main ideas as part of a continuous work (during the stated period) that not only reveals the internal coherence of his overall thought over the course of time, within which he showed different and seemingly unrelated commitments, but also gives us a powerful tool to understand the key concepts of his philosophy, such as the procedures of truth, ontology, phenomenology, and his commitment to axiomatic thinking. In this essay we aim to examine the concept of the subject in relation to the theory of discipline. We will do so by examining Badiou’s encounter with two crucial aspects of the theory of the subject discussed by Lacan: the Cartesian cogito and the relation of the subject to the mathematical infinite.
The Pleasures of Unpleasure: Jacques Lacan and the Atheism Beyond the “Death of God”
Authors: D. Mathews Peter
Published: August 2023

Although the desire to be free from God springs from humanity’s wish to enjoy pleasure without restraint, Lacan observes that humans remain neurotic and unhappy. That is because the prevailing “dead of God” form of atheism relies on the denial of a father/god, a negation that inadvertently replicates the logic of religion. Lacan, by contrast, grounds his atheism in a theory of pleasure that recognizes the role of “unpleasure” in breaking the tedium of easy, unlimited gratification. Turning to Greek tragedy, Lacan shows how the ancient world used the gods as creators of “unpleasure” to generate human jouissance. The figure of Antigone, in particular, shows how the divine function can fulfill “the true formula of atheism,” which is not “God is dead,” but rather, Lacan affirms, that “God is unconscious.”
Computer vision application for improved product traceability in the granite manufacturing industry
Authors: Martínez J. , Rigueira X. , Araújo M. , Giráldez E. , Recamán A.
Published: August 2023

The traceability of granite blocks consists in identifying each block with a finite number of colour bands that represent a numerical code. This code has to be read several times throughout the manufacturing process, but its accuracy is subject to human errors, leading to cause faults in the traceability system. A computer vision system is presented to address this problem through colour detection and the decryption of the associated code. The system developed makes use of colour space transformations and various thresholds for the isolation of the colours. Computer vision methods are implemented, along with contour detection procedures for colour identification. Lastly, the analysis of geometrical features is used to decrypt the colour code captured. The proposed algorithm is trained on a set of 109 pictures taken in different environmental conditions and validated on a set of 21 images. The outcome shows promising results with an accuracy rate of 75.00% in the validation process. Therefore, the application presented can help employees reduce the number of mistakes in product tracking.

Published: August 2023

Phishing attacks are one of the biggest security threats to personal and financial information on the internet. They are a type of cyber-attack where attackers pretend to be a trusted entity in order to trick people into revealing sensitive information, such as passwords and credit card numbers. To address this issue, a web application has been developed for detecting phishing websites. This application utilizes the Beautiful Soup library in Python to extract HTML and XML content and machine learning algorithms for detection. The application was created using the Streamlit software, making it user-friendly and easy to access through a web interface.
Environmental Tax Reform in Western Balkan Countries
Authors: Ceko Enriko , Cakrani Edmira
Published: August 2023

This chapter's goal is to provide a comprehensive description of the environmental tax reform that has been implemented in Western Balkan nations and to examine how it has been carried out. The analysis of the environmental tax's effectiveness and its contribution to the promotion of green initiatives is another goal of the chapter. Since environmental taxation has the potential to address all facets of environmental protection, the goal of environmental taxation is, in theory, to factor environmental harm or negative externalities into prices to influence production and consumption choices in an eco-friendly direction.
The Contribution of the Environmental Tax on the Reduction of Carbon Dioxide Emissions
Authors: Dâmaso Maria Goreti , Leitão Nuno Carlos
Published: August 2023

This chapter aims to analyze the environmental tax's contribution to reducing carbon dioxide emissions in Portugal and Spain. Moreover, this study analyses the impact of the use of renewable energies and the gross domestic product (GDP) on carbon dioxide emissions. The data are collected from the Organization for Economic Cooperation and Development (OECD) and Word Bank indicators from 1990 to 2019. The methodology is the time series (two- stage least squares; fully modified OLS; DOLS- dynamic OLS canonical cointegration regression, and granger causality). The unit-roots test demonstrates that the variables used in this investigation are integrated with the first differences. The results demonstrate the importance of the environmental tax and the use of renewable energies in reducing carbon dioxide emissions, both in Portugal and Spain. The results also show the positive effect of economic growth on Spain's increase in carbon dioxide emissions.
The Pivotal Role of the Internet of Things in Library Innovation
Authors: Wani Javaid Ahmad , Ayoub Arshia
Published: August 2023

In libraries, the internet of things (IoT) has enormous promise. It is not the sensor on the object, but it does have the capacity for electronic tracking and data exchange. This has created a plethora of new opportunities to improve the efficiency of libraries and, as a result, the user experience of various services. IoT has played a critical role in transforming libraries into Smart places by improving services such as “collection management,” “instruction,” “data security,” and so on. It can also allow real-time global connection of a large library system. In this context, the chapter looks to explain IoT and its numerous technologies. The study additionally indicates possible library areas for implementation and how they affect library effectiveness in terms of patrons, operations, and technological innovation. This chapter will serve as a road map for scholars, practitioners, and readers interested in IoT, technosphere, and tech habitat.

One of the many promising developments in data innovation is chatbots. They were created as a brand-new user interface that would let users communicate with services merely through chat, replacing or enhancing the need for applications or website visits. Since digitalisation is pacing up around the globe, usage of chatbots is prevalent in many domains for the interface between customers and entities. However, there is still another industry where chatbots have a considerable amount of prospect: education. In the educational sector, chatbots are equipped but to a certain extent only. The aim of the study is to create awareness about potential of chatbots in learning processes and its various applications in the academic sector. Chatbots various verticals promote digitalisation in the future of education support systems enhancing the productivity and boosting growth as the education sector of any country is the foundation of its growing future.
T-bet overexpression modulates CAR T cell effector functions
Authors: Cimons Jennifer , Degolier Kole R , Kohler Mark Eric , Fry Terry
Published: August 2023

Adoptive transfer of T cells modified with a chimeric antigen receptor (CAR) are highly effective in patients with hematologic malignancies. However, many patients relapse and CAR T cells have shown minimal efficacy against solid tumors. Our lab and others have shown that standard CAR designs fail to promote differentiation into canonical T cell subsets. CAR T cells generate both type-1 and type-2 cytokines simultaneously, challenging the traditional paradigm that Th1 and Th2 differentiation programs are mutually exclusive. We sought to control this by overexpressing the transcription factor T-bet to drive a more canonical type-1 effector response. CD28-costimulated CAR T cells overexpressing T-bet showed a reduction in type-2 cytokine production. In an immune-competent syngeneic mouse model of B cell acute lymphoblastic leukemia, T-bet overexpressing CAR T cells showed increased expansion, increased generation of KLRG1+CD127− effector T cells, and decreased expression of exhaustion-associated markers PD1, TIM3, and LAG3 through the initial CAR T cell expansion and contraction phases Despite this, Tbet overexpression drove late CAR T cell hypo-functionality and leukemic relapse. However, in 4-1BB-costimulated CAR T cells, which tend to have a weaker effector response than CD28-costimulated CAR T cells, T-bet overexpression led to increased CAR T cell potency, prolonging survival over mice treated with a 4-1BB-costimulated CAR. Furthermore, T-bet overexpression led to increased CAR T cell polyfunctionality against low-antigen density leukemia when compared to standard CAR T cells. These results demonstrate the potential of T-bet-overexpression as a strategy to modulate the strength of the CAR T cell effector response.
