Authors: Aminu Musa  , Habeebah Adamu Kakudi  , Mohammed Hassan  , Mohamed Hamada  , Usman Umar  , Maryam Lawan Salisu
Published: February 2025

As edge computing gains attention across various domains, the demand for lightweight deep learning models capable of running efffciently on resource-constrained edge devices has surged. This survey investigates the landscape of lightweight deep learning models tailored for edge computing environments. The survey explores various model compression techniques used to design and optimize deep learning models for edge deployment, including model quantization, pruning, and knowledge distillation. Emphasis is placed on strategies to reduce model size, computational complexity, and memory footprint while maintaining satisfactory performance levels. Additionally, the study examines the performances of these techniques on three real-life datasets evaluating lightweight deep learning models, highlighting the importance of balanced datasets representative of edge device deployment scenarios. Furthermore, this survey provides a comprehensive overview of the current state of lightweight deep learning models for edge devices, offering insights into design considerations, optimization techniques, and performance evaluation methodologies. The ffndings show that most of the compression techniques suffer from performance degradation, proving the existence of a trade-off between compression and performance. Therefore, we proposed a hybrid losslesscompressed model by combining pruning quantization, and knowledge distillation, to reduce parameters and weights, resulting in a lightweight model. The proposed model is three times smaller than the vanilla CNN model and achieved a state-of-the-art accuracy of 97% after compression, which shows the effectiveness of our approach. These results will serve as a valuable resource for researchers and practitioners aiming to develop efffcient and scalable deep learning solutions for edge computing applications.
Exploring the Anxiety of Action in Call Me by Your Name
Authors: Bose Suchandra
Published: February 2025

André Aciman’s novel Call Me by Your Name (2007) is divided into four parts each of which intends to capture Elio’s conflicted emotions in the purview of his doomed love for Oliver, a 24 year old scholar from America. Elio’s incessant need to impede his actions through the ambivalence of speech, wavering desires, and misconstrued ideas lays foundation for the subjectivity of action and, more acutely, his anxiety. Consequently, it becomes integral to examine the location of Elio’s anxiety either in a same-sex relationship or the universality of anxiety in the context of the novel. The essay hopes to map the similarities of the queer experience permeating across definite time periods, cultural landscape, and religious identity keeping in mind Elio’s own subjective experience. It also intends to explore the inception of anxiety in view of the text at hand, the subjectivity of action in terms of the less than hopeful resolution, and how the possibility of circumventing these anxieties is in tandem with the changing locations in the novel.
Written and Over-written: Investigating Metafictional Strategies in Janet Frame's The Carpathians
Authors: Sancheti Pooja
Published: February 2025

Unlike several movements in literature, postmodernism lacked a specific manifesto and often varied in its concerns depending on the media that it engaged with. However, on the whole, postmodernist fiction is generally characterized as being playfully (and highly) selfreflexive and self-conscious of its status as artifice, dominantly leaning towards the ‘creation’ of reality in language rather than the reflection of reality in language, celebrating the multiplicity of voices and narratives over (humanistic) faith in metanarratives (as famously stated by Jean-François Lyotard in The Postmodern Condition), indulging in intertextuality, and highlighting the discursive nature of the text, the reader, and the writer. Linda Hutcheon states that postmodernism is a cultural activity that incorporates what it contests, centralizes what is decentralized, and is, thus, a “both/and” rather than an “either/or” movement. These aspects make pastiche and parody fundamental to understanding postmodernist fiction (Hutcheon 3). All in all, postmodernist fiction revels in its status as fiction and is greatly concerned with matters of textuality, and the conflation of language and reality (within and without the fictional world). In addition to these features, the term ‘metafiction’ is conspicuously attached to the idea of a postmodern novel.
Shame and Failure of Recognition in Amitav Ghosh's The Hungry Tide
Authors: Datta Siddhant
Published: February 2025

Maurice Merleau-Ponty sees shame as a dialectic between the self and the other, as that of the master and slave. In so far as one has a body, Merleau-Ponty argues, s/he may be reduced to the status of an object beneath the gaze of another person. To regain the status as a subject, one has to seek recognition within the dialectic (MerleauPonty 193). This paper follows Merleau-Ponty’s insight into the reduction of the self to an object in the gaze of the other and draws upon this insight to read interruptions to the colonial epistemological projects that attempt to construct the other as an object of knowledge. Neocolonialism’s implication in a regime that repeatedly constitutes its other within its own terms of legibility stresses its similarities to its predecessor and a continuation of its practices of epistemological violence on its other.1 The success of decolonisation has been hampered by an uninterrupted production of marginalisation of the other within postcolonial democracies with a mere shifting of sites of domination.

Phorids, Not Gnats: Ivermectin Treatment of Scuttle Fly Myiasis in a Tennessee Nursing Home Resident - A Case Report
Authors: Faust Lynn Frierson
Published: February 2025

A well-cared-for, bedridden, and helpless 94-year-old female resident in a Tennessee nursing home experienced sudden, rapid weight loss, severe lethargy, and increasingly foul-smelling bed sores between late February and April 2022. By April 5, her modern, climate-controlled room became infested with small flies, initially identified as "gnats" by staff. Despite immediate pest control measures—removal of plants and food, spraying, sealing drains, and deploying insect traps—the infestation intensified, with hundreds of tiny flies spreading to other rooms by April 12. By April 13, the facility administration, out of options, considered isolating the patient. On April 14, her family identified the flies as parasitoid scuttle flies, Megaselia scalaris (Lowe, 1866) (Diptera: Phoridae), a species capable of human myiasis.

Following a literature review, a simple treatment protocol by Sayeed et al. (1) was administered on April 15 and 16, resulting in the complete elimination of M. scalaris within 3 days. The patient subsequently lived an additional 7 months with improved quality of life, awareness, appetite, and comfort, without further weight loss, progression of bedsores, or visible insect presence. Zevo insect traps remained in place for monitoring, and the patient received weekly ivermectin prophylaxis against further phorid myiasis and COVID-19, which was prevalent in the facility. Awareness of M. scalaris myiasis in vulnerable patients and effective treatment protocols remains limited among healthcare personnel across much of the United States.

Keywords: Ivermectin, phorids, Megaselia scalaris, parasitoid, scuttle flies, gnats, elderly, incapacitated, fly larvae.

Published: February 2025

With the continuous development of China's industrial process, the social demand for electricity is increasing. Under the influence of new energy grid connection to build smart grid, the stability and security of the power grid system are particularly affected by the unstable characteristics of new energy. In view of the protection of the safe and stable operation of power, it is very necessary to monitor the information of power equipment, especially for the unpredictable power failure analysis is the key to ensure the safety of electricity use. However, due to the wide variety and huge quantity of power equipment and the frequent fluctuation of monitoring data affected by the natural environment, the amount of data of equipment information will grow rapidly in a short time, which has exceeded the ability of ordinary computers to handle. With the increasing size and complexity of power equipment, its fault prediction and life cycle management become very important. The emergence of big data analysis technology provides a new way to solve this problem. This paper first expounds the importance and status quo of power equipment fault prediction and life cycle management, then introduces the application principle and related technologies of big data analysis in this field, and then discusses the power equipment fault prediction method and life cycle management strategy based on big data analysis in detail. Finally, the effectiveness of this method is verified through practical cases. The future development is also prospected.

Analysis of Chinese Students' cultural and linguistic personality based on slang
Authors: He Yanli , Elistratov Vladimir  Stanislavovich
Published: February 2025

The purpose of this study is to analyze some features of the cultural and linguistic personality of modern Chinese students, manifested in the use of youth slang expressions. The scientific novelty of the proposed approach lies in the fact that the study of youth slang becomes part of the work on compiling a summary portrait of the cultural and linguistic personality of modern Chinese students in Russian and Chinese universities. Slang not only reflects the specific features of the cultural and linguistic personality, but also largely determines its uniqueness and complexity. The materials and results of the research were analyzed from the point of view of the national mentality of modern Chinese students, which is manifested in the choice of certain speech expressions, psychophysiological characteristics, as well as in the behavior. The research methods: the analysis of materials (a sample of vocabulary from electronic Chinese-Russian dictionary, as well as theoretical articles) and observation. The author concludes that the features of the cultural and linguistic personality of Chinese students are manifested through value dominants reflected in slang. The main criterion for selecting slangisms was the expression of the following most important value attitudes of Chinese students - the degree of independence from the group, the degree of manifestation of personality in class, sincerity in relations with teachers, attitude to food, attitude to work, attitude to the desired profession after graduation, attitude to life. The specified dominants associated with the axiological dimension of the image of the world in many aspects determine the speech behavior of students. Thus the slang becomes one of the most expressive forms of the culture and expresses the consciousness of modern youth.

Maritime routes in Kepulauan Riau Province, Indonesia, serve as pivotal entry points for narcotics trafficking and smuggling within the Southeast Asian region. This study delves into the establishment and evolution of these illicit networks by examining three key variables: demographic and socio-economic characteristics, operating structures and classifications, methods, means, and funding sources. Leveraging an analysis of 355 court rulings records, the authors constructed a comprehensive dataset encompassing these variables. The findings underscore the intricate nature of narcotics trafficking networks, spanning from production to distribution, with involvement at various levels across diverse demographics. Notably, the exorbitant earnings potential, with couriers fetching up to 700 million rupiahs, underscores the financial allure of the narcotics trade. Moreover, the research elucidates the pivotal role of public transportation modes, including ships, planes, and speed boats, in facilitating these illicit activities. Furthermore, the intricate web of relationships among defendants, ranging from familial to social ties, underscores the complex nature of these networks. The authors argue that effective law enforcement and prevention strategies necessitate a nuanced understanding of these social dynamics to combat narcotics operations effectively. The implication is that law enforcement and prevention must focus on specific individuals or groups and recognize patterns of social relationships utilized in narcotics operations.

As predicted, Indonesia will experience a demographic bonus, starting in 2020 as indicated by the population of productive citizens group (15-64 years) which is larger than other population groups. In response to the situation, fundamental efforts need to be made to ensure that the demographic surplus can be an economic driver. In early 2020, the government launched the Pre-employment Card program. This program was launched in the midst of the Covid-19 pandemic which disrupted many aspects of society, especially the economy and health. This research examines the Pre-employment Card program from the point of view of the empowerment concept. Research is carried out by tracing government policies and regulations in carrying out this program. The results of the study found that the Pre-employment Card program seeks to implement empowerment goals as it seeks to build the strength of participants to engage in economic activities (work and entrepreneurship). The program develops 2 of 3 empowerment strategies by Jim Ife through policy and planning to provide fairer access to resources and opportunities to participate in community life as well as education and awareness raising to increase strength of the subject of empowerment.

In order to provide more accurate theoretical guidance for the improvement of photoelectric properties of chalcogens doped silicon, the lattice structure, stability, band structure, density of state and optical properties of (S, Se) co-doped silicon were systematically investigated based on the first principles, and the related properties were compared with those of S-doped and Se-doped silicon. The calculated results show that the photoelectric characteristics of S-doped Si and Se-doped Si are extremely similar, with a new impurity band appearing in their bandgaps. This new impurity band is primarily due to the contribution of the 3s state electrons of S and the 4s state electrons of Se, promoting the absorption of low-energy photons and increasing the optical absorptivity of doped Si in the near infrared region. Compared with monocrystalline silicon, the optical absorption spectra of S-doped Si and Se-doped Si show a new peak at 0.6 eV, which is caused by the transition of electrons from the impurity band to the conduction band. (S, Se) co-doped Si exhibits good stability at operating temperature; and two impurity bands appear between the valence band and conduction band, which are formed by electrons from the 3s state of S and the 4s state of Se, respectively. The optical absorptivity of （S，Se）co-doped Si is greatly improved in the low energy region compared to that of single doped Si, with a new absorption peak appearing at 0.65 eV, similar to the formation observed in singly doped Si. However, due to the indirect transition process between two impurity energy bands, the absorption peak of (S, Se) co-doped Si is larger in the low energy region. Compared with S-doped silicon and Se-doped silicon with the same concentration, the optical absorptivity of the (S, Se) co-doped is significantly improved in the range of 0.81 eV to 1.06 eV. This study provides theoretical guidance for (S, Se) co-doped Si in the field of photoelectron such as infrared photodetectors and solar cells.
Rapid riparian ecosystem recovery in low-latitudinal North China following the end-Permian mass extinction
Authors: Guo Wenwei , Tian Li , Chu Daoliang , Shu Wenchao , Benton Michael J , Liu Jun , Tong Jinnan
Published: February 2025

The greatest mass extinction at the end-Permian, 252 million years ago (Ma), led to a tropical dead zone on land and sea. The speed of recovery of life has been debated, whether fast or slow, and terrestrial ecosystems are much less understood than marine. Here, we show fast reestablished riparian ecosystems in low-latitude North China within as little as ∼2 million years (Myr) after the end-Permian extinction. The initial ichnoassemblages in shallow lacustrine and fluvial facies of late Smithian age are monospecific, devoid of infaunalization, with apparent size reduction. In the following Spathian, newly identified medium-sized carnivores, plant stems, root traces, coupled with improved ichnological criteria and significantly increased infaunalization, suggesting a relatively complex, multi-level trophic structured riverain ecosystem had been rebuilt. Specifically, burrowing behavior had re-emerged as a key life strategy not only to minimize stressful climatic conditions, but possible to escape predation.
A contextual fear conditioning paradigm in head-fixed mice exploring virtual reality
Authors: Krishnan Seetha , Dong Can , Ratigan Heather , Morales-Rodriguez Denisse , Cherian Chery , Sheffield Mark
Published: February 2025

Contextual fear conditioning is a classical laboratory task that tests associative memory formation and recall. Techniques such as multi-photon microscopy and holographic stimulation offer tremendous opportunities to understand the neural underpinnings of these memories. However, these techniques generally require animals to be head-fixed. There are few paradigms that test contextual fear conditioning in head-fixed mice, and none where the behavioral outcome following fear conditioning is freezing, the most common measure of fear in freely moving animals. To address this gap, we developed a contextual fear conditioning paradigm in head-fixed mice using virtual reality (VR) environments. We designed an apparatus to deliver tail shocks (unconditioned stimulus, US) while mice navigated a VR environment (conditioned stimulus, CS). The acquisition of contextual fear was tested when the mice were reintroduced to the shock-paired VR environment the following day. We tested three different variations of this paradigm and, in all of them, observed an increased conditioned fear response characterized by increased freezing behavior. This was especially prominent during the first trial in the shock-paired VR environment, compared to a neutral environment where the mice received no shocks. Our results demonstrate that head-fixed mice can be fear conditioned in VR, discriminate between a feared and neutral VR context, and display freezing as a conditioned response, similar to freely behaving animals. Furthermore, using a two-photon microscope, we imaged from large populations of hippocampal CA1 neurons before, during, and following contextual fear conditioning. Our findings reconfirmed those from the literature on freely moving animals, showing that CA1 place cells undergo remapping and show narrower place fields following fear conditioning. Our approach offers new opportunities to study the neural mechanisms underlying the formation, recall, and extinction of contextual fear memories. As the head-fixed preparation is compatible with multi-photon microscopy and holographic stimulation, it enables long-term tracking and manipulation of cells throughout distinct memory stages and provides subcellular resolution for investigating axonal, dendritic, and synaptic dynamics in real-time.
Associations between physical activity and emotional and behavioural problems in Chinese children and adolescents with intellectual disabilities
Authors: Zhong Yecheng , Zhou Junjie , Li Niuniu , Xu Wenhong , Qi Jing
Published: February 2025

Background and purpose

Emotional and behavioural problems (EBPs) are the two main forms of mental health problems that hinder the social interactions, learning and daily living of children and adolescents with intellectual disabilities (ID). Studies have shown that sufficient moderate-to-vigorous physical activity (MVPA) is associated with mental health outcomes among children and adolescents with typically developing (TD). However, these associations have not been fully studied in children and adolescent with ID, especially in samples from China. Therefore, this study aimed to examine the associations between MVPA and EBPs in Chinese children and adolescents with ID.

Methods

A cross-sectional survey was conducted with 116 students with ID (35.34% girls) aged 6–18 years. The wGT3-BT accelerometer was used to measure physical activity (PA), and the Chinese version of the parent-rated Strengths and Difficulties Questionnaire (SDQ) was used to assess the participants’ EBPs. A series of binary logical regression analyses was conducted to examine the ability of the MVPA guideline attainment in predicting EBPs in the total sample.

Results

The descriptive results showed that 43.97% of children and adolescents with ID present with EBPs. After controlling for age, sex, ID severity and weight status, logistic regression analysis indicated that the participants who meet the MVPA guideline exhibited significantly lower odds ratio for emotional symptoms (OR = 0.334, 95% CI [0.114–0.975], p = 0.045), peer problems (OR = 0.071, 95% CI [0.015–0.328], p < 0.001) and total difficulties (OR = 0.192, 95% CI [0.069–0.535], p = 0.002) compared with those who did not meet the guidelines.

Conclusion

The prevalence of EBPs in Chinese children and adolescents with ID remains high. Children and adolescents with ID meeting the MVPA guideline were more likely to have lower risks for emotional symptoms, peer problems and total difficulties than those who did not meet the guidelines. Future research adopting longitudinal or interventional designs to determine the relationships between PA and EBPs in this population are expected.
Unusual Presentation of Legionella as an Acute Flaccid Quadriparesis in a Case of Guillain-Barre Syndrome

Published: February 2025

Guillain-Barré Syndrome (GBS) is a rare polyradiculoneuropathy of the peripheral nerves and, occasionally, the cranial nerves, causing dysfunction, segmental demyelination, and/or axonal degeneration. GBS is considered an autoimmune disease because the body’s own immune system attacks its own tissues. There is a strong association between GBS and preceding acute infectious illness. Aetiology is unknown in most cases. GBS has been less commonly reported in association with Legionella. Furthermore, unusual GBS-related clinical signs might lead to confusion and incorrect diagnoses, like transverse myelitis, spinal cord compression, stroke, infections, myasthenia, and periodic paralysis. To establish the diagnosis of GBS, patient history, electrophysiological assessments, neurological evaluations, and Cerebrospinal Fluid (CSF) analyses are equally important. Hereby, the authors present a case report of 75-year-old male patient who presented with a history of fever spikes and diarrhoea 10 days prior, followed by the acute onset of ascending paralysis and hypertension. A systemic examination revealed right eye ptosis, loss of power in the bilateral lower limbs, areflexia, and diminished sensory function. Further evaluation through nerve conduction studies showed findings suggestive of demyelinating axonal sensory-motor polyneuropathy involving all four limbs. Based on the clinical suspicion of an acute infectious illness history followed by ascending paralysis, the patient was investigated for the cause of GBS, which was found to be Legionella. The patient was treated with plasmapheresis and physiotherapy and is now on regular follow-up.
Mechanisms of slope flows
Authors: Ingel Leo
Published: February 2025

If a fluid or gaseous medium in a gravity field is limited from below by an inclined surface that is colder than the medium, then a cooled layer of the medium is formed near this surface, which, being relatively dense, flows down under its own weight. When heated from below, movements in the opposite direction occur. Slope flows of this type (in particular, “katabatic winds”) are very common in the lower layers of the atmosphere and are of great practical importance. The article shows that even the simplest theoretical models of such currents sometimes lead to results that are paradoxical at first glance. For example, in the classical stationary Prandtl model, the flow of the mass of flowing air increases indefinitely with a decrease in the angle of inclination of the surface, although, it would seem, over a horizontal surface, slope currents, on the contrary, should be absent. Some other non-trivial features of slope flows are also indicated and their physical causes are explained.

Use of bottom sediments of the Tsimlyansk Reservoir as organic fertilizer
Authors: Stepanyan Oleg
Published: February 2025

The potential of using bottom silt from one of the biggest water table and the most stocked artificial reservoirs in the steppe zone of southern Russia for purposes of Rostov Region eastern and northeastern arid cite soil fertility restoring has been studied. According to studies conducted in August 2023, the organic carbon content in the bottom sediments of the Tsimlyansk Reservoir varied from 0,54 to 3,07% with a neutral and slightly alkaline reaction of the environment. In general, there was no chemical contamination, except for the exceeded maximum permissible concentration of zinc recorded within one station, and a slight excess for manganese. However, all the samples correspond to the technical requirements for their use as fertilizers, and the exception is a single exceeded manganese content and sporadic cases of low phosphorus and organic matter levels. It was found that in total, low molecular weight PAHs phenanthrene (42%), fluorene (23%), biphenyl (19%) - make the greatest contribution to the individual score in the composition of the studied samples. The content of the remaining PAHs is variable, but does not reach such high values. The predominant toxic substance is benzapyrene, the content of which in all the studied samples comply with sanitary and hygienic standards. The bottom sediments of the Tsimlyansk Reservoir meet the technical requirements for their use as organic fertilizers. The results of the study confirmed the possibility of using bottom sediments of the Tsimlyansk Reservoir to increase soil fertility, especially unproductive and degraded ones.

Optimization of Teak Growth, Productivity and Wood Quality Through Implementation of Sound Silvicultural Techniques - A Review
Authors: Rathod Chetan Bhanu , Inamati S S , M Hanumantha , M R Jagadish , H N Karthik , Rathod Aravind B.
Published: February 2025

Teak (Tectona grandis L. f.) is one of the most important tropical hardwood tree species in world and popularly known as “King of timbers”. It is the most valued species for structural and non-structural applications and has commanded a premium price in global market. With diminishing supply of timber from the natural forests, attention has now been shifted considerably towards fast grown plantation species to meet the timber deficit. The variation in the growth, quality and distribution of teak is mostly dictated by soil-site characteristics. Natural teak forests occur on black and red soils developed from the underlying rock viz. sandstone, granite-gneiss and basalt. The shift in teak plantation management from government sectors to private farm lands and plantation companies led to intensive management of teak plantations and consequent reduction in rotation age of plantation. Silviculture techniques like thinning, pruning, spacing, weeding, weeding and improvement felling etc., act as a tool for commercial tree farming to attain the maximum growth and productivity. Stand management practices such as plant spacing, thinning and pruning affect diameter, height growth, commercial volume of timber and wood quality. The implementation of thinning and pruning regimes in the clonal teak plantation as part of intensive silvicultural techniques helps to improve the growth and productivity of teak plantation. Thinning and pruning regimes can enhance the mechanical properties without having a serious alteration in the physical properties of clonal teak wood. Lower wood density and durability of the short rotation teak compared to the long rotation teak will restrict its utilization to some extent for both indoor and outdoor applications. With the adoption of sound silvicultural practices specific to the species, the prodcutivity can be enhanced without comprimising the quality of the produce.

Aims: The study aims to investigate temperature tolerance in rice by assessing the polymorphism in microsatellite (SSR) marker segregation between heat sensitive recipient parent (KAU Manu Ratna) and heat tolerant donor parent (Nagina 22).
Place and Duration of Study: Department of Plant Physiology, College of Agriculture, Kerala Agricultural University, Vellanikkara, Thrissur, Kerala, India between January to April, 2022.
Methodology: The rice genotypes namely KAU Manu Ratna (susceptible recipient parent) and Nagina 22 (tolerant donor parent) exhibiting contrasting response to heat stress tolerance were used for the study. Leaf samples collected from 25-day old seedlings were used for DNA extraction. A set of previously identified 44 heat tolerance Rice Micro satellite (RM) markers spanning across the 12 chromosomes of rice were used for the parental polymorphism study. The DNA fragments were amplified by polymerase chain reaction using RM markers, followed by agarose gel electrophoresis. The amplified DNA fragments were documented using gel documentation system and polymorphism patterns were analyzed.
Results: The result of the genetic polymorphism survey between the rice genotypes Nagina 22 (heat-tolerant) and KAU Manu Ratna (heat-sensitive) revealed that 20 markers out of 44 SSR markers employed in the study were found to be polymorphic between the two genotypes. A polymorphism of 45.45% highlights the genetic diversity between the parental lines, providing essential markers for mapping QTLs linked to traits conferring heat stress tolerance in rice and strengthen the heat stress marker assisted breeding programmes.
Conclusion: The study highlights the potential of micro satellite marker analysis in identifying genetic polymorphisms between heat-tolerant and heat-sensitive rice genotypes. The findings pave way to strengthen marker-assisted breeding strategies, especially by enabling precise delineation of QTLs conferring heat-stress tolerance. The results thus offer a strong foundation for developing climate resilient rice cultivars to address the challenges of climate induced heat stress on global food security.

India is blessed with varied agro-climatic conditions which have paved a way to grow variety of fruits in different seasons of the year. The Awadh region of Uttar Pradesh are suitable for the cultivation of wood apple. In wood apple the existing variability is low due to the problem of un exploitation and lack of awareness. Considering the wide genetic diversity in wood apple (Feronia limonia L.) in terms of qualitative characters, an extensive survey of diversity rich area of Awadh region of Uttar Pradesh was done and twenty nine genotypes in the form of fruits were collected from the different locations during 2021-23 to identify elite genotypes having desirable horticultural traits. The experimental design employed in this study was Complete Randomized Block Design. The results revealed rich genetic variations with respect to individual fruit length (5.33-9.49 cm), fruit width (5.57-9.54 cm), fruit weight (113.26-263.45 g), shell thickness (0.14-0.43 mm), seed length (4.04-8.46 mm), seed width (1.95-4.17 mm), seed thickness (1.34-1.69 mm), seed weight per fruit (25.25-31.06 g), number of seeds per fruit (134.50-456.0), among different genotypes. The different genotypes also exhibited wide range of variability in qualitative characters, viz. total soluble solids (10.22-18.14 0Brix), acidity (2.12-6.09 %), TSS/acidity ratio (1.67-8.71), reducing sugars (0.85-1.30 %), non reducing sugars (0.67-1.06 %), total Sugars(1.55-2.40 %), Vitamin C (15.16-27.95 mg/ per 100 g) and pectin content (1.03-2.09 %) among all 29 genotypes studied for their qualitative characters.

Guest‐ Editor of this 2 Peter J Baldwin explores the sculptural and drawn work of Royal Academician Michael Sandle and discusses the artist's multilayered and multiscaled oeuvre that bristles with haunted, painful pasts – lest we forget!
Digital Ectoplasm and the Infinite Architecture of the Fulldome
Authors: Phillips Mike
Published: July 2024

Suggesting a curious comparison between the Victorian séance and the contemporary world of immersive virtual environments, Mike Phillips, Professor of Interdisciplinary Arts at the University of Plymouth, and Director of Research at i‐DAT.org, describes the new capabilities of the fulldome, which uses notions of the automatic movements of the planchette, the wooden token that traverses the alphanumeric surface of the notorious Ouija board, as a model for the development of a quasi‐participatory audience interface he dubs the ‘phage’. Clusters of phage can be manipulated by the viewer‐occupiers of the dome to instigate all manner of formal, scalar and conceptual transpositionings.

Nano‐heterointerface engineering has been demonstrated to influence interfacial polarization by expanding the interface surface area and constructing a built‐in electric field (BEF), thus regulating electromagnetic (EM) wave absorption. However, the dielectric‐responsive mechanism of the BEF needs further exploration to enhance the comprehensive understanding of interfacial polarization, particularly in terms of quantifying and optimizing the BEF strength. Herein, a “1D expanded 2D structure” carbon matrix is designed, and semiconductor ZnIn2S4 (ZIS) is introduced to construct a carbon/ZIS heterostructure. The cross‐dimensional nano‐heterointerface design increases interface coupling sites by expanding the interface surface area and induces an increase in the Fermi level difference on both sides of the interface to modulate the distribution of interface charges, thereby strengthening the BEF at the interface. The synergistic effect leads to excellent EM absorption performance (minimum reflection coefficient RCmin = −67.4 dB, effective absorption bandwidth EAB = 6.0 GHz) of carbon/ZIS heterostructure. This work introduces a general modification model for enhancing interfacial polarization and inspires the development of new strategies for EM functional materials with unique electronic behaviors through heterointerface engineering.
