Heating, ventilating, and air-conditioning (HVAC) are critical mechanical systems maintained in the oil and gas (O&G) industry. However, there are no guidelines to define and measure the competencies of the personnel who execute HVAC maintenance in the O&G industry in Malaysia. The research objective is to develop a competency instrument for HVAC maintenance technical executors in the O&G industry in Malaysia. A questionnaire survey was designed in the study by using a quantitative approach. The developed instrument has been distributed to 163 respondents using cluster sampling based on four regions. The analysis results through Winstep Software V.3.69.1.11 identified 19 competencies with 119 sub-competencies in technical skill, three competencies with 30 sub-competencies in non-technical skill, and four competencies with 18 sub-competencies in core personality. These competency instruments were pertinent to academic and professional communities based on perspectives from the industry. For practical purposes, the HVAC competency instruments may assist the employees in their career advancement to be competent.
Efficient Constrained Real-World Problem-Solving Using Gradient-Based Mutation Manta Ray Foraging Optimization (GM-MRFO)

Published: November 2024

This paper presents a Gradient-based Mutation Manta ray foraging optimization (GM-MRFO) that is designed to solve real-world optimization problems with constraints. GM-MRFO combines the basic strategy of MRFO with the Gradient-based Mutation (GM) strategy, which is a feasibility-and-solution repair strategy adopted from the ϵ-Matrix-Adaptation Evolution Strategy (
MAgES). MRFO algorithm is not immune to the common problems confronted by constrained optimization algorithms where constraints in the optimization problem are incompatible, and a solution that satisfies all constraints does not exist. In such cases, the MRFO algorithm may not be able to find a feasible solution. Another challenge is the optimization algorithm converges to a solution that is not globally optimal. By introducing the GM strategy and using Jacobian approximation in finite differences, GM-MRFO can improve the feasibility of solutions throughout the search process, which enables it to handle constraints more effectively than its predecessor. The proposed algorithm's performance is evaluated by assessing the accuracy of the best solution produced, the feasibility rate, mean of violation, success rate, and the ranking based on a ranking scheme in the Congress on Evolutionary Computation 2020 (CEC2020). Specifically, GM-MRFO achieved a feasibility rate of 100% on 47 out of 57 CEC2020 real-world problems and improved adequately best-known solutions.

Microwave Ablation Therapy for Hepatocellular Carcinoma: The Effect of Metabolic Heat on Temperature Distribution
Authors: Harvan Heaven Josiah , Wahyudi Slamet , Winarto Winarto
Published: November 2024

Hepatocellular carcinoma is the main cause of liver cancer and one of the most occurring cancers worldwide. Microwave Ablation (MWA) is a method to destroy cancer cells by heating tumours above 50°C. Cancerous tissues can have high metabolic heat rates and affect temperature gain and distribution in thermal therapies. This research clarifies the metabolic heat effects in MWA therapy of liver cancer. Using Pennes Bioheat transfer equation with finite element numerical method, this research simulates temperature distribution with metabolic heat value ranging from 368,1 W/m3 to 29000 W/m3. The heat generated by metabolic heat is lower than the MWA heat source. However, the temperature increase should be considered as it can increase healthy surrounding tissue temperature to dangerous levels.

Published: November 2024

Herbal remedies for oral care are increasingly popular due to their safety, affordability, and compatibility with the mouth's natural bacterial balance. This study develops and evaluates herbal tooth powder using Quercus infectoria (oak galls), Triphala (Amla, Haritaki, Bibhitaki), Liquorice (Glycyrrhiza glabra), black salt, and calcium carbonate to prevent oral infections. The objective was to create an effective alternative to conventional dental products. The tooth powder was formulated and tested through physicochemical, rheological, microbiological, patch, and sensory evaluations. The pH level of 5 is ideal for oral applications, balancing effective hygiene and gentleness. Physicochemical evaluations show a moisture content of 1.64% (indicating stability and low microbial risk), an ash value of 0.58% (acceptable limits), and a bulk density of 4g/ml (ensuring good flow and consistent dosing). The effective minimum inhibitory concentration of 0.1 mg/ml highlights the active compounds' potency in inhibiting bacterial growth. Key findings showed it had strong antibacterial, antimicrobial, anti-inflammatory, and antioxidant properties. Tannic acid from Quercus infectoria was effective against oral infections, while Triphala and Liquorice added antibacterial benefits and improved flavour. This study underscores the potential of herbal tooth powders as a natural, effective solution for oral hygiene and infection prevention.

Authors: Randive Vaishali , Taru Tanuja , Shinde Vanita , Pooja Rana  , Bhagat Rani
Published: November 2024

Phosphorus is crucial for plant growth and productivity, and its scarcity in soil negatively affects crop yields. A major portion of chemical phosphate fertilizer precipitates with soil minerals, making it unavailable for plant growth. Phosphate-solubilizing microorganisms play a pivotal role in enhancing phosphorus availability, facilitating better nutrient absorption, and ultimately boosting plant growth. This article presents a brief overview of the phosphorus status in Indian soil, discusses the various forms of phosphorus and its dynamics across different soil types, and analyses the factors involved, highlighting the importance of phosphorus management for sustainable agriculture. Physiological and molecular mechanisms of microbial phosphate solubilization provide deep insights into exploring PSMs for managing phosphorous in different soil types. It also provides a path for the necessity to explore the multifarious plant growth-promoting traits of PSMs underscoring its applicability for sustainable agricultural practices with viable economy. The mechanism of solubilization of phosphorus has been discussed to understand the role of microorganisms in different soils. The study highlights the role of significant microorganisms in developing tailored consortia of PSMs and other plant growth-promoting rhizobacteria (PGPR) based on the chemical composition of the soil, along with an integrated nutrient approach incorporating PSMs. This review offers valuable insights into harnessing PSMs and their practical applications, facilitating their broader adoption in agricultural systems to maintain soil health.

Published: November 2024

Medicinal plants have been used for the treatment of many ailments since time immemorial. The pharmacological significance of these plants is attributed to the presence of secondary metabolites which are greatly affected by the changes in the climatic conditions. This study investigates the effect of seasonal variations on the phytochemical constituents and biological activities of Holoptelea integrifolia leaves and bark in Kangra district, Himachal Pradesh, India. The antimicrobial activity and minimum inhibitory concentration of various plant extracts were determined using agar well diffusion and resazurin dye methods. The qualitative and quantitative analysis of phytochemical, besides antioxidant activity, were compared in all samples during different seasons. The experimental results revealed that the chloroform extracts of leaves and bark of plants during winter season were most effective against S. flexneri with highest zone of inhibition (ZOI) of 19.5±0.12mm and 22.6 ±0.32mm at 4 mg/40 μμl, respectively. However, MIC of leaf and bark extracts in case of S. flexneri were 0.3125 mg/100 μl and 0.0781 mg/100 μl, respectively. Phytochemical analysis of H. integrifolia confirmed significant seasonal variation, with phenols, flavonoids and terpenoids highest in the winter season, while alkaloids dominated in autumn season. The chloroform extract of H. integrifolia leaves and bark exhibited highest antioxidant activity in DPPH assay (78.81±0.12% & 81.41±0.24%) followed by H2O2 and phosphomolybdenum at 300μg/ml conc. respectively. The results of the present work revealed that the bark of H. integrifolia during winter season exhibited better antimicrobial activity than the leaves, providing a valuable basis for the future efforts in developing novel herbal drugs.
‘Todas nosotros’: géneros gramaticales y construcciones identitarias en los discursos de mujeres de la guerra de Malvinas
Authors: SALERNO PAULA
Published: November 2024

Este artículo se centra en los discursos de mujeres que participaron en la Guerra de Malvinas en 1982. Desde un enfoque interaccional del discurso, se analiza el caso de una entrevista televisiva grupal. Se observa que la combinación de géneros gramaticales masculino y femenino para referirse a sí mismas da cuenta de procesos de identificación atravesados por tensiones entre voces individuales y dos voces sociales: la bélico-militar y la de la feminindad. Así, las hablantes configuran sus identidades para incidir en la memoria colectiva sobre Malvinas y, con ello, cambiar un estado de situación social que las involucra.
Event-horizon-scale Imaging of M87* under Different Assumptions via Deep Generative Image Priors
Authors: Feng Berthy T. , Bouman Katherine L. , Freeman William T.
Published: November 2024

Reconstructing images from the Event Horizon Telescope (EHT) observations of M87*, the supermassive black hole at the center of the galaxy M87, depends on a prior to impose desired image statistics. However, given the impossibility of directly observing black holes, there is no clear choice for a prior. We present a framework for flexibly designing a range of priors, each bringing different biases to the image reconstruction. These priors can be weak (e.g., impose only basic natural-image statistics) or strong (e.g., impose assumptions of black hole structure). Our framework uses Bayesian inference with score-based priors, which are data-driven priors arising from a deep generative model that can learn complicated image distributions. Using our Bayesian imaging approach with sophisticated data-driven priors, we can assess how visual features and uncertainty of reconstructed images change depending on the prior. In addition to simulated data, we image the real EHT M87* data and discuss how recovered features are influenced by the choice of prior.

Using integrated spectra for two gravitationally lensed galaxies from the JWST TEMPLATES Early Release Science program, we analyze faint auroral lines, which provide direct measurements of the gas-phase chemical abundance. For the brighter galaxy, SGAS1723+34 (z = 1.3293), we detect the [O iii] λ4363, [S iii] λ6312, and [O ii] λ
λ7320, 7330 auroral emission lines, and set an upper limit for the [N ii] λ5755 line. For the second galaxy, SGAS1226+21 (z = 2.925), we do not detect any auroral lines, and report upper limits. With these measurements and upper limits, we constrain the electron temperatures in different ionization zones within both of these galaxies. For SGAS1723+34, where auroral lines are detected, we calculate direct oxygen and nitrogen abundances, finding an N/O ratio consistent with observations of nearby (z ∼ 0) galaxies. These observations highlight the potent combination of JWST and gravitational lensing to measure faint emission lines in individual distant galaxies and to directly study the chemical abundance patterns in those galaxies.
The A2Π–X2Σ+ Band System of ScO for M-type Star Spectral Analysis
Authors: Lavy Léo , Pastorek Adam , Bernath Peter F
Published: November 2024

M-type stars are the most abundant stars in our Galaxy. Their visible spectra are characterized by strong TiO and VO absorption bands with occasional ScO bands near 6000–6100 Å. This region corresponds to the A2Π–X2Σ+ band system and can be used to measure the abundance of ScO. In this work, a new Doppler-limited resolution spectrum of ScO obtained in a hollow-cathode experiment is presented. The A2Π–X2Σ+ electronic transition is analyzed with special care dedicated to fitting the

states 2 ≤ v ≤ 6. The modeled interaction of the two states reproduces the experimental data remarkably well. New equilibrium constants are extracted from the fit. Band strengths are calculated with the help of a scaled transition dipole moment function, previously calculated with ab initio methods. Finally, a line list of the A2Π–X2Σ+ band system is provided, including Einstein A coefficients and oscillator strengths. Using this line list, the spectrum of ScO can be simulated for different temperature and pressure conditions in stellar atmospheres.
Cross-correlating Dark Sirens and Galaxies: Constraints on H
0 from GWTC-3 of LIGO–Virgo–KAGRA
Authors: Mukherjee Suvodip , Krolewski Alex , Wandelt Benjamin D. , Silk Joseph
Published: November 2024

We apply the cross-correlation technique to infer the Hubble constant (H
0) of the Universe using gravitational-wave (GW) sources without electromagnetic counterparts (dark sirens) from the third GW Transient Catalog (GWTC-3) and the photometric galaxy surveys 2MPZ and WISE-SuperCOSMOS, and combine these with the bright siren measurement of H
0 from GW170817. The posterior on H
0 with only dark sirens is uninformative due to the small number of well-localized GW sources. Using the eight well-localized dark sirens and the binary neutron star GW170817 with electromagnetic counterpart, we obtain a value of the Hubble constant

km s−1 Mpc−1 (median and 68.3% equal-tailed interval) after marginalizing over the matter density and the GW bias parameters.

Published: November 2024

Fauna inventories reduce biodiversity knowledge gaps by providing comprehensive data on species distribution, richness, and abundance. Furthermore, they identify undocumented species and enhance understanding of ecosystem dynamics and conservation needs. The richness and abundance of amphibian species were studied in two Semideciduous Seasonal Forest areas in the municipalities of Potiraguá (Serra Azul) and Itarantim (Serra do Mandim) in southwestern Bahia, Brazil. Active visual and acoustic surveys were conducted in 24 forest interior transects, two stream transects, and two permanent ponds investigated in the study area. Opportunistic encounters during team movements were also recorded. The richness was 46 amphibian species distributed in 14 families and 26 genera. Approximately half of the species were shared between the two areas, while 11 species were exclusive to Serra Azul and another nine were found only in Serra do Mandim. Cluster analysis for 42 locations in Atlantic Forest, Caatinga, and Cerrado, in a presence/absence matrix with 216 species, revealed that the composition of the amphibians found in Serra do Mandim and Serra Azul is similar to other sampled locations in the northeastern region of Minas Gerais, close to the study site, which are considered transitional between the Atlantic Forest and the Caatinga. Our results demonstrate that the remaining forest fragments in the region, although small and isolated, still sustain a high richness of amphibians with species restricted to the Atlantic Forest and Bahia, such as Bahius bilineatus, Ololygon strigilata, Aplastodiscus weygoldti and Vitreorana eurygnatha, and others considered typical of the Caatinga, such as Leptodactylus troglodytes and Physalaemus cicada. Additionally, we sampled potential new species, filled occurrence gaps, and expanded the geographical range of Pseudis fusca.

Em jeito de síntese… A Ordem de Santiago em Sesimbra
Authors: Costa João
Published: November 2024

Sesimbra integra o imperium da Ordem de Santiago no ano de 1236, quando o território é doado pela Coroa aos espatários. A partir de então, o senhorio desenvolve todo um conjunto de relações sociais, políticas, económicas e institucionais no espaço tutelado por Sesimbra. Neste âmbito e ao longo de toda a Idade Média (séculos xiii–xvi), os modelos de gestão da Ordem de Santiago na comenda de Sesimbra vão adaptar‑se ao devir histórico, vivendo‑se momentos de crispação com as instituições locais, nomeadamente a partir do século xiv, quando Sesimbra vê partes do seu território autonomizarem‑se e Setúbal bloquear o seu crescimento. Procuraremos fazer um balanço historiográfico da questão, procurando reinterpretar alguns dados e lançar pistas para caminhos ainda a percorrer.
Do Conflito Latente à Vizinhança Pacífica
Authors: Costa João
Published: November 2024

A história de Sesimbra, desde a sua primeira conquista pelas hostes cristãs em 1165, não se forjou sozinha. O seu devir está intrinsecamente ligado à relação que estabeleceu com as localidades e circunscrições administrativas existentes em seu redor, assim como com outras mais distantes, como Lisboa, mas igualmente relevantes. A teia de acordos e desacordos de âmbito político, económico, comercial, religioso, entre outros múltiplos aspectos com os concelhos de vizinhos, como Almada, Palmela e Setúbal, permitem‑nos percepcionar as lógicas de desenvolvimento, afirmação e de importância relativa de Sesimbra no contexto local e reinol. Partindo da leitura do Tombo da vila de Sesimbra e de outra documentação análoga emanada de outras entidades como a Coroa e o Mosteiro de Santos de Lisboa, tentaremos reconstruir algumas dessas teias relacionais que marcaram cerca de 400 anos da história deste concelho.
De l’assignation spatiale à l’assignation économique

Published: November 2024

L’article vise à étudier le lien entre la gestion spatiale des réfugié·es et leur mise au travail. Il montre à partir d’un travail d’exploitation des archives que le système des centres a été conçu selon une logique de dispersion à resituer dans une généalogie coloniale affectant différentiellement les réfugié·es selon leurs positions dans les rapports sociaux de genre et de race. Dans la période contemporaine prévaut une logique de confinement qui fait de la gestion de l’hébergement des exilé·es une priorité, un modèle et un viatique des politiques de placement économique.
« Vous devez travailler avec nous ». Participation des réfugiées aux programmes de lutte contre les violences de genre en Tanzanie
Authors: Surie von Czechowski Aditi
Published: November 2024

La Tanzanie, pays hôte historique pour les réfugié·es, les a de plus en plus confiné·es au cours de la dernière décennie dans des camps où il leur est interdit de travailler et de s’intégrer dans les communautés locales. Cet article examine l’impact du confinement humanitaire sous l’angle des programmes de lutte contre les violences de genre, à partir d’une recherche ethnographique conduite dans le camp de Nyarugusu, en Tanzanie. Je m’appuie sur des conversations avec des femmes congolaises demandant assistance en tant que survivantes de violences de genre, afin d’éclairer les effets distributifs de ces programmes. Soutenu par la logique des droits humains et de l’éducation libérale, le confinement humanitaire réifie la « culture » en tant que lieu de violence et a pour effet paradoxal d’accroître le préjudice causé aux réfugiées en exigeant que la souffrance soit visible, audible et lisible, et en réécrivant la responsabilité comme un impératif moral et une injonction à posséder et à partager un certain type de savoir.

Bodies on the screen : A short essay on performative memes
Authors: Tanni Valentina
Published: November 2024

“Bodies on the Screen: A Short Essay on Performative Memes” explores the intersection of contemporary visual art and internet culture through an analysis of memetic performances. Focusing on David Horvitz’s viral “freezer project” as a catalyst, the essay examines the dynamics of repetition and variation within memetic systems, highlighting the role of instructions and the body as a medium of expression. Drawing parallels with more recognized art practices, such as the body-centric works of Bruce Nauman and Erwin Wurm, the article discusses the transformative power of performative memes, which often blur the line between art and everyday life. Through case studies like planking and viral challenges, the essay delves into the concept of “new media idiocy,” coined by Russian scholar Olga Goriunova, and explores the emergence of performative memes on platforms like TikTok, where the human body becomes a central tool for self-expression and identity exploration.

Des colonies à la Porte Dorée : représentations, interprétations et enjeux de médiation
Authors: Lelong Lieko
Published: November 2024

Le Palais de la Porte Dorée, construit pour l’Exposition coloniale internationale de 1931, est une œuvre architecturale monumentale conçue pour célébrer l’Empire colonial français à son apogée. L’iconographie de la puissance française, omniprésente, se manifeste notamment dans le bas-relief qui orne la façade du bâtiment, ainsi que sur les fresques de l’ancienne salle des fêtes où s’impose une vision idéalisée et triomphante de l’expansion coloniale outre-mer. En décalage avec l’esthétique et le regard contemporain, ces représentations soulèvent la question de leur réception par les publics. D’objet historique et patrimonial, le Palais devient un support de réflexion, témoignant de l’évolution des regards sur l’époque coloniale, et invitant à aborder les questions de représentations des mémoires.

Securing Automatic Speaker Verification Systems Using Residual Networks
Authors: Chakravarty Nidhi , Dua Mohit
Published: November 2024

Spoofing attacks are a major risk for automatic speaker verification systems, which are becoming more widespread. Adequate countermeasures are necessary since attacks like replay, synthetic, and deepfake attacks, are difficult to identify. Technologies that can identify audio-level attacks must be developed in order to address this issue. In this chapter, the authors have proposed combination of different spectrogram-based techniques with Residual Networks34 (ResNet34) for securing the automatic speaker verification (ASV) systems. The methodology uses Mel frequency scale-based Mel-spectrogram (MS), gamma scale-based gammatone spectrogram (GS), Mel filter bank-based Mel frequency cepstral spectrograms (MCS), acoustic pattern-based acoustic pattern spectrogram (APS), gammatone filter bank-based gammatone cepstral spectrogram (GCS), and short-time Fourier transform-based short Fourier spectrogram (SFS) methods, one by one, at front of the proposed audio spoof detection system. These spectrograms are individually fed to ResNet34 for classification at the backend.

Machine learning has revolutionized fields like medicine and information security, enabling advances in brain tumor classification, diabetes detection, and cancer diagnosis. This study emphasizes progress in dermatology, specifically in the detection and classification of skin diseases such as skin cancer using machine learning and deep learning techniques. Additionally, the chapter explores how these methods can benefit steganography. Malignant melanoma, with high mortality rates according to the World Health Organization, is a key focus. The researcher developed a model that integrates deep learning algorithms, machine learning methods, image analysis, and various feature extraction techniques to investigate skin cancer using different datasets. Evaluation metrics like recall, precision, F1-score, sensitivity, specificity, and accuracy are employed to measure the model's effectiveness. These technologies not only improve early detection and treatment of skin diseases but also offer new approaches to enhancing secure communication

Pediatric genital warts successfully treated with photodynamic therapy

Published: November 2024

Genital warts (GWs) are the most common sexually transmitted infections worldwide, caused by the human papillomavirus (HPV). In adults, the primary mode of transmission is through sexual contact, whereas in children it can occur through skin-to-skin or skin-to-mucosa contact and be sexual or non-sexual. The increasing prevalence of GWs in children has renewed the interest in therapeutic management which still presents a unique challenge, being influenced by many variables including size, quantity, and location of warts, as well as the presence of comorbidities. Photodynamic therapy (PDT) has already shown encouraging results in treating viral warts in adult patients, but its use is still not standardized in the pediatric population. On this topic, we report the case of an otherwise healthy 5-year-old child affected by GWs, successfully treated with three sessions of PDT with 10% 5-aminolaevulinic acid (ALA), at one-month intervals. Our case is paradigmatic of the potentiality of PDT to treat difficult lesions in a pediatric setting.
Terraced landscapes: risk and liability
Authors: Delogu Gabriele , Boccia Lorenzo , Mari Giuseppina
Published: November 2024

Terraced landscapes are preserved elements of the human-influenced environment, maintained by ongoing agricultural activities. Farmers are subject to the periodic collapse of terraces, which are repaired by means of traditional techniques. Unless it can be proven that the collapse was accidental, the owner is liable for the damage caused by the collapse of the terraces or landslides. This topic, applied to Minori (Amalfi Coast, Italy), is interesting for two reasons. First, with the advancement of scientific knowledge, the unpredictability of events diminishes and the liability increases. Second, the intensive construction at the base of the terraces and the economic value of the buildings, enhanced by the landscape context, expose the owners to claims for damages from third parties that are disproportionate to the agricultural income, including claims for amnestied illegal constructions. The result has been an increase in the renunciation of property rights by farmers in areas of high hydro-geological risk. However, the State, which becomes the owner, denies the validity of property relinquishments made by owners solely to transfer risk, cost, and liability to the state treasury.  This paper discusses these issues, going beyond the Italian case study, and proposes a different risk allocation related to territorial governance. This study reveals a discrepancy in government decision making and suggests that the division of risk into multiple components could be a solution to this inconsistency.

Published: November 2024

Context:

To determine the relationship between the Pederson difficulty index and the modified Parant scale and to assess the effectiveness of the Pederson difficulty index in predicting the difficulty of mandibular third molar extractions.

Settings and Design:

This cross-sectional study recruited participants with indications for third molar extractions. Pederson’s difficulty index was used to evaluate the anticipated difficulty of preoperative mandibular third molar extraction. Surgical extraction of impacted third molars was done under local anesthesia and patients were then assessed postoperatively with the Modified Parant Scale.

Methods:

In this study, 85 participants indicated for surgical extraction of mandibular third molars under local anesthesia were enrolled between February 2018 and July 2018. The relationship between Pederson’s difficulty index modified Parant scale and duration of extraction was evaluated.

Statistical Analysis Used:

Sociodemographic variables of study participants were summarized with descriptive statistics. Student’s T-test was utilized for mean differences between groups and correlations were computed between Pederson and modified Parant scale.

Results:

This study comprised 85 participants with a mean age of 25.8 years ± 4.6, showing no significant difference across genders (P = 0.87). Pederson difficulty index demonstrated a sensitivity of 46.4% and a specificity of 89.5% and a moderate correlation (0.35, P < 0.001) was observed between Pederson difficulty index and surgery duration, ditto, between Pederson and modified Parant scores (0.36, P < 0.001).

Conclusion:

In conclusion, our study underscores the importance of pre-operative assessment for mandibular third molar extraction, highlighting the Pederson Difficulty Index’s moderate predictive value but emphasizing concerns about its sensitivity.
Fuzzy Allocation Optimization Algorithm for High-Density Storage Locations with Low Energy Consumptions
Authors: Gao Ziyi , Huang Linze , Wu Zhigang , Wu Zhenyan , Li Chunhui
Published: November 2024

The global demand for stored and processed data has surged due to the development of IoTs and similar computational structures, which has led to further energy consumption by concentrated data storage facilities and thus the demands of global energy and environmental needs. The current paper introduces Fuzzy Allocation Optimization Algorithm to mitigate energy consumption in high storage density settings. It uses the principles of Fuzzy logic to determine the best way to assign the tasks in relation to storage density necessity, urgency and energy consumption. Thus, the proposed approach incorporates fuzzy inference systems with multi-objective optimization methods where location of storage is dynamically assessed and assigned according to energy efficiency parameters. The findings of the simulation and case study prove that the algorithm is successful in saving energy while at the same time lowering storage I/O response time, which provides a viable solution to energy issues in evolving data centres. This work satisfies the lack of energy efficient algorithms in high density storage areas and responds to the recent calls for green technology and smart utilization of resources in the energy field. The findings are used in the promotion of significant IT infrastructures towards developing the next generation of energy efficient data centers with respect to Future Internet and evolving energy web environments.
Ammann Bars for Octagonal Tilings
Authors: Fernique Thomas , Porrier Carole
Published: November 2024

Ammann bars are formed by segments (decorations) on the tiles of a tiling
such that forming straight lines with them while tiling forces non-periodicity.
Only a few cases are known, starting with Robert Ammann's observations on
Penrose tiles, but there is no general explanation or construction. In this
article we propose a general method for cut and project tilings based on the
notion of subperiods and we illustrate it with an aperiodic set of 36 decorated
prototiles related to what we called Cyrenaic tilings.
String attractors of Rote sequences
Authors: Dvořáková Lubomíra , Hendrychová Veronika
Published: November 2024

In this paper, we describe minimal string attractors (of size two) of
pseudopalindromic prefixes of standard complementary-symmetric Rote sequences.
Such a class of Rote sequences forms a subclass of binary generalized
pseudostandard sequences, i.e., of sequences obtained when iterating
palindromic and antipalindromic closures. When iterating only palindromic
closure, palindromic prefixes of standard Sturmian sequences are obtained and
their string attractors are of size two. However, already when iterating only
antipalindromic closure, antipalindromic prefixes of binary pseudostandard
sequences are obtained and we prove that the minimal string attractors are of
size three in this case. We conjecture that the pseudopalindromic prefixes of
any binary generalized pseudostandard sequence have a minimal string attractor
of size at most four.
