Normal Separation Axiom on Fuzzy Bitopological Space
Authors: Miah Saikh Shahjahan Miah , Amin M R
Published: June 2024

In our paper, we present three novel concepts related to the normal separation property within the realm of fuzzy bitopological spaces (FPTS), specifically focusing on pairwise fuzzy normal bitopological spaces (FPN). These notions are introduced in a quasi-coincidence sense, and we establish relationships between our propositions and other existing ones. Furthermore, we provide proofs demonstrating that all the introduced concepts exhibit the ‘good extension’ property. Notably, we observe that our notions maintain their characteristics under one-one, onto, fuzzy pairwise open (FP-open), fuzzy closed (FP-closed), and fuzzy pairwise continuous (FP-continuous) mappings.
Umesamiska – forskningshistorik, substantivböjning och sydgräns
Authors: Larsson Lars-Gunnar
Published: June 2024

Ume Saami, the second-most southern of the Saami languages, is almost extinct, despite revitalisation efforts taking place. In the 17th century, Lycksele became a scholarly centre in the Swedish part of Sápmi, due in part to the school for Saami boys, which was founded there in 1631. Ume Saami also formed the basis for an orthography that was used in Sweden well into the 19th century. At the beginning of the 20th century, Ume Saami attracted the interest of researchers as it was the southernmost Saami language with a (rudimentary) gradation. At that time, the lack of gradation was the conclusive criterion for a dialect as belonging to South Saami. This topic is still raised today, when there are discussions as to whether place names on maps and road signs should be written using either Ume or a South Saami orthography. This article presents a survey of the research history of Ume Saami, where a surprising opposition between extensive collections of dialect material and very few publications can be noted. As for the question of the southern border of Ume Saami, a couple of morphological arguments, namely the forms of the illative singular and the comitative plural, indicate that the borderline should be drawn not along the Ume River but along the watershed south of the river. This result is in accordance with the results in Larsson 2012 and with Rydving’s study on lexical variation (2016).

Pyogenic granuloma of the hard palate leading to alveolar cleft: a case report
Authors: Song Woo Jin , Choi Hyun Beom , Tak Min Sung
Published: June 2024

This case report describes a rare occurrence of pyogenic granuloma (PG) in the hard palate deviating from its typical gingival location that led to the formation of an alveolar cleft. The aggressive growth pattern of the lesion, with atypical progression from a pedunculated nodule to an alveolar cleft, raised concern. The diagnosis was based on magnetic resonance imaging and computed tomography findings, which revealed a tadpole-shaped lesion originating from the midline hard palate. The differential diagnosis included a minor salivary gland tumor. Surgical excision was performed under general anesthesia and resulted in a mucosal defect without nasolabial fistula formation or bone exposure. The palatal defect was packed with oxidized regenerated cellulose and closed with Vicryl Rapide sutures, both of which contributed to the patient’s successful outcomes. Our comprehensive approach, extending across the stages of surgical planning, execution, and postoperative care, demonstrated the advantages of a multidisciplinary strategy for the accurate diagnosis and effective treatment of palatal PGs. This report makes a meaningful contribution to the existing literature on common oral lesions by emphasizing the importance of a broad differential diagnosis and a systematic approach to oral pathologies. It also raises clinical awareness of PGs with atypical presentations and the diagnostic challenge that they pose.
Prevention and treatment of microstomia
Authors: Ki Sae Hwi , Park Tae Jun
Published: June 2024

The mouth, located in the lower third of the face, is a uniquely visible structure. It serves as a vital organ both aesthetically and functionally, playing a key role in speech, expression, and fundamental oral functions. Consequently, any alterations or defects in its shape, due to various causes, can lead to aesthetic and functional deficiencies. These issues may also result in challenges with social interactions and a decrease in confidence. In cases of microstomia, various surgical approaches are proposed based on the location, extent, shape, and cause of the defect, leading to numerous case reports. Plastic surgeons are proficient in oral reconstruction; however, cases of microstomia are relatively rare, which reduces their familiarity and interest in these cases. Additionally, preferences for oral size and shape vary according to factors such as geographical region and ethnicity, further complicating the functional definition of microstomia. Therefore, both subjective patient and physician judgments play crucial roles in the diagnosis and treatment of microstomia, as these may vary depending on individual and societal aspects. This review aims to classify the various causes and definitions of microstomia, as well as its non-surgical and surgical treatment options, with the goal of the treatment of this condition.

Authors: Uçar Elalmış Özgül , Arslan Koray
Published: June 2024

Cardiac myxoma is the most commonly diagnosed benign cardiac tumor. It is usually located in the left atrium and typically arises from the foramen ovale in approximately 75% of the cases, in the right atrium in 23%, and in the ventricles in only 2%. Symptoms depend on its size, mobility, and location. Neurological complications resulting from cardiac myxoma are seen in 20% to 25% of patients. We report a case of right ventricular myxoma and patent foramen ovale which was complicated by stroke. The mass was surgically excised and patent foramen ovale was closed.
Including the change in natural capital stock and environmental degradation in Peruvian mining GDP and NNP
Authors: Orihuela Carlos Enrique , Chumpitaz Añi Victor Carlos Michel , Dávila García José Yasser
Published: June 2024

This study adjusts the net national product (NNP) and gross domestic product (GDP) of the Peruvian mining sector by incorporating natural capital depreciation, new discoveries, and environmental degradation during the period 1994–2018. The results suggest that NNP has been overestimated, on average, by 172 % to 210 %, which is attributed to the omission of natural depreciation. When GDP was corrected, the overestimation fluctuated between 64 % and 72 %. This underscores the importance of including natural capital depreciation, especially in countries whose economy is highly dependent on extractive industries, as is the case of Peru.
Mechanical Performance of Basalt and Glass Woven Composites
Authors: Vashıshtha Arvınd , Sharma Dhirendra
Published: June 2024

This study systematically evaluates the mechanical properties of glass and basalt high-performance fibers in woven fabric-reinforced composites with thermoplastic and thermoset matrices. Investigating responses to diverse quasi-static and dynamic impact loads, the research emphasizes the growing interest in composites as alternatives to conventional metals. Examining basalt and glass fibers within different matrices, the study optimizes composite materials by scrutinizing tensile strength, flexural strength, and edge-wise impact resistance. Combining literature review and experiments, the research highlights basalt fibers for their high tensile strength and environmental sustainability. Key findings show that, under quasi-static conditions, thermoset composites excel in in-plane load bearing, while thermoplastic composites exhibit exceptional edge-wise impact resistance. Additionally, the study notes the superior flexural properties of thermoplastic-based basalt composites over glass, with dynamics shifting under thermoset matrices. This underscores the profound influence of both reinforcement and matrix materials on composite mechanical properties. Basalt thermoplastic composite (TPB2DFRC) outperforms Glass-based counterpart (TPG2DFRC) in tensile properties, demonstrating superior elasticity and plasticity for enhanced deformation resistance. In flexural characteristics, TPB2DFRC excels, displaying higher modulus, strength, and flexibility compared to Glass-based thermoplastic composite (TPG2DFRC), highlighting the superior mechanical attributes of Basalt composites. The Izod impact properties showcase Basalt composites’ exceptional resistance, with higher impact strength and energy values, surpassing Glass counterparts. This underscores the potential of Basalt-based materials for applications requiring superior resilience to dynamic impact loading.

This study has two parts as determining traffic LOS and nanoscale analyses on the filters which can collect nanoparticle materials sourced by exhaust waste. Therefore, at first, determination of the traffic behaviour as the level of service (LOS) in Sıhhiye campus of Hacettepe University in Ankara was studied. Then, exhaust gas analysis by using facing masks was conducted for different parameters and these masks were used to collect and analyse exhaust on them. The parameters were determined as vehicle and fuel types, filter masks, sampling distances respect to exhaust source. The measurements and samplings were realized for the vehicles which are public cars and service minibuses which use different fuel types as petrol, eco-diesel and diesel. Additionally, 5 different filter types were used to analyse traffic behaviour as exhaust gas may affect human health. For this reason, different mask types with different specified parameters, which are using as face masks for health and a new type was prepared by Argiope lobata spider silk membrane, were also investigated in relation to the filtered exhaust gases. Measurements were made for three different distances as 30, 60 and 90 cm from exhaust pipe output and with a constant sampling time range of 3 min. Apart from the previously known microscopic and macroscopic analyses on exhaust gases, it was examined whether the exhaust outputs frequently spread nanoparticle waste or not by using SAXS analyses on samples. As a result of the study, relation with traffic conditions with clear transportation can be affirmed. Additionally, the study reported important outcomes, such as a new designed filter mask material, which prevents the nanoparticles waste material, the critical distance from the exhaust sources and the importance of different fuel usage.
Decorative art of Russian painted spinning wheels and the art of painted lacquer products in China during the Warring States of Qi Lien
Authors: du juan
Published: June 2024

The article is devoted to the comparison of Mezen painted spinning wheels actively produced in Arkhangelsk province (Russia) in the XIX century and objects of Chinese art of Qi Lien painting of the Warring Kingdoms period. In this era, the skill of creating Chinese lacquer products was very developed, and the spinning wheel industry of the XIX century became the basis for the existence of a vital craft for Russian people. The spinning wheels were decorated with colored paintings with repetitive plots. The subjects of the study represent the most important part of the folk art of the two cultures, reflecting at the same time the aesthetic and spiritual preferences of the population. Their prevalence in both cases made it possible to identify the commonality of artistic techniques used by folk craftsmen. Scientific work assigns an important role to the techniques of manufacturing household items that demonstrate the prevailing artistic environment at the time of their regular use. The leading method of research is formal stylistic analysis, revealing characteristic compositional features. Comparative analysis makes it possible to identify similarities and differences in the works of DPI, which make it possible to hypothesize a paradoxical objective community. Considerable attention is also paid to the coloristic analysis and symbolic meaning of the murals. The scientific novelty of the study is due to the presence of a very limited number of sources mentioning the possible similarity of the two fields of folk art, none of which is fully devoted to the formal and stylistic features of objects created by unknown masters. The article closes this gap, aiming to discover specific unifying features. Its tasks become a detailed study of plots, compositions, techniques and materials used. The research allows us to come to the conclusion that the work of both Russian and Chinese artists reflected the main artistic aspirations of contemporaries, who often endowed objects and phenomena with symbolic meaning. There is a noticeable interest in the use of wood, the use of warm shades and the embedding of patterns in compositions. There is a similarity in the desire to reflect reality when including plant and animal motifs in their works. Also, the decorative and planar nature of the painting combines the rich details of the product. The relevance of the research is due to the convergence of Russian and Chinese cultures, so that the study of the issue can contribute to finding new points of spiritual contact.

When an incident high-energy heavy ion beam enters into solid material, the energy deposition density along the ion flight path can change the temperature and pressure of macroscopic target, and new material defects can be created under the high-pressure and high-density conditions. To accurately control the extreme state in material generated by heavy ion beam, it is necessary to conduct in-depth research on the energy deposition density of ions and ascertain the new potential defects in matter. Reported in this work is the new experiment conducted on the HIRFL-CSR at Lanzhou, with the extracted 264 MeV/u Xe36+ ion beams irradiating an LiF crystal target. The emission spectrum of the LiF is measured in-situ. Moreover, the crystal color is observed to vary along the ion path, and X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) are used to observe the potential new phases at different positions of crystal through the target dissociation method.

It is apparent that in No. 3-front a new phase around 52.6° is found in XRD result, which is believed to be LiF3 (LiF+F2) structural phase and appears in the Bragg peak region of Xe ions in LiF. Furthermore, to verify this result, a similar experiment is done by using a 430 MeV/u 84Kr26+ ion beam, and the stacked layered LiF target is analyzed after the irradiation. The XPS result shows more complex defects aggregating in the Bragg peak region of Kr ions in LiF at room temperature. In previous study, such complex defects were all created under high temperature conditions. We find that these complex defects can be produced around the Bragg peak region of ions in LiF at room temperature, resulting in a temporally high temperature and high pressure condition. This paper can provide some experimental evidences and references for the target material modification in heavy ion beam driven high-energy density physics research.

It takes more than twenty years for normal colorectal mucosa to develop into metastatic carcinoma. The long time window provides a golden opportunity for early detection to terminate the malignant progression. Here we aim to enable liquid biopsy of T1a stage colorectal cancer (CRC) and precancerous advanced adenoma (AA) by profiling circulating small extracellular vesicle (sEV)-derived RNAs. We exhibited a full RNA landscape for the circulating sEVs isolated from 60 participants. A total of 58,333 annotated RNAs were detected from plasma sEVs, among which 1,615 and 888 sEV-RNAs were found differentially expressed in plasma from T1a stage CRC and AA compared to normal controls (NC). Then we further categorized these sEV-RNAs into 6 modules by a weighted gene coexpression network analysis and constructed a 60-gene t-SNE model consisting of the top 10 RNAs of each module that could well distinguish T1a stage CRC/AA from NC samples. Some sEV-RNAs were also identified as indicators of specific endoscopic and morphological features of different colorectal lesions. The top-ranked biomarkers were further verified by RT-qPCR, proving that these candidate sEV-RNAs successfully identified T1a stage CRC/AA from NC in another cohort of 124 participants. Finally, we adopted different algorithms to improve the performance of RT-qPCR-based models and successfully constructed an optimized classifier with 79.3% specificity and 99.0% sensitivity. In conclusion, circulating sEVs of T1a stage CRC and AA patients have distinct RNA profiles, which successfully enable the detection of both T1a stage CRC and AA via liquid biopsy.
Serotonergic and dopaminergic neurons in the dorsal raphe are differentially altered in a mouse model for parkinsonism
Authors: Boi Laura , Johansson Yvonne , Tonini Raffaella , Moratalla Rosario , Fisone Gilberto , Silberberg Gilad
Published: June 2024

Parkinson’s disease (PD) is characterized by motor impairments caused by degeneration of dopamine neurons in the substantia nigra pars compacta. In addition to these symptoms, PD patients often suffer from non-motor comorbidities including sleep and psychiatric disturbances, which are thought to depend on concomitant alterations of serotonergic and noradrenergic transmission. A primary locus of serotonergic neurons is the dorsal raphe nucleus (DRN), providing brain-wide serotonergic input. Here, we identified electrophysiological and morphological parameters to classify serotonergic and dopaminergic neurons in the murine DRN under control conditions and in a PD model, following striatal injection of the catecholamine toxin, 6-hydroxydopamine (6-OHDA). Electrical and morphological properties of both neuronal populations were altered by 6-OHDA. In serotonergic neurons, most changes were reversed when 6-OHDA was injected in combination with desipramine, a noradrenaline (NA) reuptake inhibitor, protecting the noradrenergic terminals. Our results show that the depletion of both NA and dopamine in the 6-OHDA mouse model causes changes in the DRN neural circuitry.
Neural interactions in the human frontal cortex dissociate reward and punishment learning

Published: June 2024

How human prefrontal and insular regions interact while maximizing rewards and minimizing punishments is unknown. Capitalizing on human intracranial recordings, we demonstrate that the functional specificity toward reward or punishment learning is better disentangled by interactions compared to local representations. Prefrontal and insular cortices display non-selective neural populations to rewards and punishments. Non-selective responses, however, give rise to context-specific interareal interactions. We identify a reward subsystem with redundant interactions between the orbitofrontal and ventromedial prefrontal cortices, with a driving role of the latter. In addition, we find a punishment subsystem with redundant interactions between the insular and dorsolateral cortices, with a driving role of the insula. Finally, switching between reward and punishment learning is mediated by synergistic interactions between the two subsystems. These results provide a unifying explanation of distributed cortical representations and interactions supporting reward and punishment learning.

Sleep and feeding patterns lack strong daily rhythms during early life. As diurnal animals mature, feeding is consolidated to the day and sleep to the night. In
Drosophila
, circadian sleep patterns are initiated with formation of a circuit connecting the central clock to arousal output neurons; emergence of circadian sleep also enables long-term memory (LTM). However, the cues that trigger the development of this clock-arousal circuit are unknown. Here, we identify a role for nutritional status in driving sleep-wake rhythm development in
Drosophila
larvae. We find that in the 2
nd
instar larval period (L2), sleep and feeding are spread across the day; these behaviors become organized into daily patterns by the 3
rd
instar larval stage (L3). Forcing mature (L3) animals to adopt immature (L2) feeding strategies disrupts sleep-wake rhythms and the ability to exhibit LTM. In addition, the development of the clock (DN1a)-arousal (Dh44) circuit itself is influenced by the larval nutritional environment. Finally, we demonstrate that larval arousal Dh44 neurons act through glucose metabolic genes to drive onset of daily sleep-wake rhythms. Together, our data suggest that changes to energetic demands in developing organisms trigger the formation of sleep-circadian circuits and behaviors.

Animal behaviour alternates between stochastic exploration and goal-directed actions, which are generated by the underlying neural dynamics. Previously, we demonstrated that the compositional Restricted Boltzmann Machine (cRBM) can decompose whole-brain activity of larval zebrafish data at the neural level into a small number (∼100-200) of assemblies that can account for the stochasticity of the neural activity (van der Plas et al., eLife, 2023). Here, we advance this representation by extending to a combined stochastic-dynamical representation to account for both aspects using the recurrent temporal RBM (RTRBM) and transfer-learning based on the cRBM estimate. We demonstrate that the functional advantage of the RTRBM is captured in the temporal weights on the hidden units, representing neural assemblies, for both simulated and experimental data. Our results show that the temporal expansion outperforms the stochastic-only cRBM in terms of generalization error and achieves a more accurate representation of the moments in time. Lastly, we demonstrate that we can identify the original time-scale of assembly dynamics by estimating multiple RTRBMs at different temporal resolutions. Together, we propose that RTRBMs are a valuable tool for capturing the combined stochastic and time-predictive dynamics of large-scale data sets.

I dette prosjektet undersøker vi fra lærerens perspektiv hva som er sammenhengen mellom øving og dybdelæring i kunst og håndverk­undervisning. Tradisjonelt er øving knyttet til repetisjon av tekniske ferdigheter. Men vi plasserer oss teoretisk innenfor øving som en grunnleggende form for læring som involverer hele eleven og kan settes i sammenheng med dybdelæring. Det vil si at øving og dybdelæring involverer ikke bare tenkning, men også kropp, sanser og følelser. Vi ser på øving og dybdelæring som forandringsprosesser som skjer i eleven selv (Aggerholm & Standal, 2021; Bollnow, 1969, 1976; Dahl et al., 2019; Friesen & Koerrenz, 2017; Merleau-Ponty, 1994; Ruud, 1983; Østern et al., 2021). Prosjektet har en feno­menologisk tilnærming da vi gjennom kvalitative intervjuer søker innsikt i grunnskolelæreres personlige undervisningserfaringer (Gill, 2020; Kvale & Brinkmann, 2021). Høsten 2021 ble det gjennomført intervjuer med 9 lærere som underviser i kunst og håndverk ved ulike barne- og ungdomsskoler i Norge. Gjennom det teoretiske perspek­tivet analyserer vi funnene og diskuterer først øving og dybde­læring som forandringsprosesser. Videre diskuterer vi mer spesifikt for­andrings­­prosesser for å utvikle håndlag og utvikling av prosess­ferdig­heter. Vi har også avdekket utfordringer med sammen­hengen mellom øving og dybdelæring. Hovedsakelig er utfordringene knyttet til uklar­heter rundt progresjon, tidspress og elevenes manglende utholden­het.. Undersøkelsen bidrar til å se øving og dybdelæring fra andre perspektiver enn det rent kognitive.

A review of reinforcement learning based hyper-heuristics
Authors: Li Cuixia , Wei Xiang , Wang Jing , Wang Shuozhe , Zhang Shuyan
Published: June 2024

The reinforcement learning based hyper-heuristics (RL-HH) is a popular trend in the field of optimization. RL-HH combines the global search ability of hyper-heuristics (HH) with the learning ability of reinforcement learning (RL). This synergy allows the agent to dynamically adjust its own strategy, leading to a gradual optimization of the solution. Existing researches have shown the effectiveness of RL-HH in solving complex real-world problems. However, a comprehensive introduction and summary of the RL-HH field is still blank. This research reviews currently existing RL-HHs and presents a general framework for RL-HHs. This article categorizes the type of algorithms into two categories: value-based reinforcement learning hyper-heuristics and policy-based reinforcement learning hyper-heuristics. Typical algorithms in each category are summarized and described in detail. Finally, the shortcomings in existing researches on RL-HH and future research directions are discussed.

The volcano rabbit (Romerolagus diazi) is a lagomorph endemic to the central mountains of the Trans-Mexican Volcanic Belt and is classified as threatened at extinction risk. It is a habitat specialist in bunchgrass communities. The annual wildfires that occur throughout its distribution range are a vulnerability factor for the species. However, the effects of wildfires on volcano rabbit populations are not fully understood. We evaluated the occupancy and change in the volcano rabbit relative abundance index in the burned bunchgrass communities of the Ajusco-Chichinautzin Mountain Range during an annual cycle of wildfire events. Additionally, we assessed the factors that favor and limit occupation and reoccupation by the volcano rabbit using the relative abundance index in burned plots as an indicator of these processes. The explanatory factors for the response of the volcano rabbit were its presence in the nearby unburned bunchgrasses, the height of three species of bunchgrass communities, the proportion of different types of vegetation cover within a 500 m radius around the burned plots, heterogeneity of the vegetation cover, and the extent of the wildfire. Statistical analyses indicated possible reoccupation in less than a year in burned bunchgrass communities adjacent to unburned bunchgrass communities with volcano rabbits. The relative abundance index of volcano rabbits was not favored when the maximum height of the Muhlenbergia macroura bunchgrass community was less than 0.77 m. When the vegetation around the burned plots was dominated by forest (cover >30% of the buffer) and the fire was extensive, the number of latrines decreased per month but increased when the bunchgrass and shrub cover was greater around the burned plots. While the statistical results are not conclusive, our findings indicate a direction for future projects, considering extensive monitoring to obtain a greater number of samples that contribute to consolidating the models presented.
