title: The evolution of the printed Bengali character from 1778 to 1978.
Creators: name: Ross, Fiona Georgina Elisabeth
Publisher: name: SOAS University of London
Year: 1988

description: The thesis traces the evolution of the printed image of the Bengali script from its inception in movable metal type to its current status in digital photocomposition. It is concerned with identifying the factors that influenced the shaping of the Bengali character by examining the most significant Bengali type designs in their historical context, and by analyzing the composing techniques employed during the past two centuries for printing the script. Introduction: The thesis is divided into three parts according to the different methods of type manufacture and composition; 1. The Development of Movable Metal Types for the Bengali Script Particular emphasis is placed on the early founts which lay the foundations of Bengali typography. Part 1 is subdivided into three sections, viz. Europeans in India, European Ventures, and Indigenous Ventures. 2. Mechanical Typefounding and Composition of Bengali In assessing the adaptation of the Bengali script for mechanical composition, attention is paid to those developments which precipitated the transition of printing in India from a craft to an industry. 3. Photocomposition of the Bengali Script The advantages of photocomposition are appraised in relation to new technical constraints imposed on type design. The description of the latest stage in the evolution of the printed Bengali character relates the practical implementation of this study's findings, viz. a new typesetting scheme and typeface design for the Bengali script. The Conclusion considers the new methodology adopted for the development of digital Bengali founts and its relevance to the production of all vernacular typeforms. The Epilogue discusses Bengali typewriter characters and low-resolution character shapes. It also considers the implications of new technology that places the design and production of founts in the hands of the non-professional designer. The thesis is intended to be of interest to the indologist, printing historian, type designer and type manufacturer. It comprises 11 chapters and includes 178 illustrations.

description: Ensemble Kalman--Bucy filters (EnKBFs) are an important tool in Data Assimilation that aim to approximate the posterior distribution for continuous time filtering problems using an ensemble of interacting particles. In this work we extend a previously derived unifying framework for consistent representations of the posterior distribution to correlated observation noise and use these representations to derive an EnKBF suitable for this setting as a constant gain approximation of these optimal filters. Existence and uniqueness results for both the EnKBF and its mean field limit are provided. The existence and uniqueness of solutions to its limiting McKean-Vlasov equation does not seem to be covered by the existing literature. In the correlated noise case the evolution of the ensemble depends also on the pseudoinverse of its empirical covariance matrix, which has to be controlled for global well posedness. These bounds may also be of independent interest. Finally the convergence to the mean field limit is proven. The results can also be extended to other versions of EnKBFs.

description: High-entropy oxides (HEOs), containing at least five principal cations, have recently emerged as promising photocatalysts for hydrogen production via water splitting. Despite their high potential, the impact of the cation mixtures on photocatalytic activity remains poorly understood. This study investigates the high-entropy photocatalyst TiZrHfNbTaO11 using first-principles calculations combined with experimental methods to elucidate the effects of various elements on electronic structure and water splitting performance. The results indicate that the HEO exhibits a bandgap comparable to TiO2 polymorphs rutile, brookite and anatase. Cations with lower electronegativity, such as hafnium and zirconium, provide the strongest water adsorption energy, serving as active sites for water adsorption. Additionally, the co-presence of highly electronegative cations like niobium and tantalum adjacent to hafnium and zirconium enhances charge transfer to water molecules, improving splitting efficiency. These findings suggest novel strategies for designing high-entropy photocatalysts by synergistic incorporating cations with different electronegativities.

title: A critical edition and a study of the commentary on the qur'anic reading of Nāfi': Sharh ̣al-durar al-lawāmi', by Muḥammad ibn 'Abd al-Malik al-Mintūrī
Creators: name: Al-Uwisheq, Abdullah
Publisher: name: SOAS University of London
Year: 1988

description: The Thesis aims at presenting a critical edition of "Sharh al-Durar al-Lawami'" by the Andalusian scholar al-Minturi (834/1431), and also at studying the Qur'anic Reading of Nāfi'. The Thesis falls into two parts. Part One, an introductory survey, consists of four Chapters. Chapter I deals with al-Minturi's life and times, firstly a brief account of the political and literary environment of the Nasrid Kingdom of Granada is given, than al-Minturi's life and works are discussed. Chapter II studies Nafi''s Reading, its introduction to Andalusia and its spread there, examining in particular how and why it became the dominant Reading in that region. Chapter III discusses the "Durar" as the standard text for the study of NafiC's Reading, and how it rapidly attracted great interest among the students of Qir'aat of different places and ages. Al-Minturi's commentary is a very important product of that interest, tor it is a well-researched and documented work. Chapter IV is devoted to explaining the method of editing the text, the layout of the text, the apparatus criticus, and the scope of the commentary notes. Part Two consists of the edited text, in which al-Minturi presents a thorough account of Nafi''s Reading and its major characteristics. The author furnished his book with an Appendix dealing with phonetic classification and points of articulation. The Thesis is in two volumes, and for convenience of handling, part of the Arabic text is included in Volume One, whereas the rest of the text together with the commentary notes are incorporated in Volume Two.

title: An introduction to the written works of Nawal al-Sa'dawi.
Creators: name: Horsey, Glynis A.
Publisher: name: SOAS University of London
Year: 1988

description: Nawal al-Sa'dawi is an Egyptian doctor and feminist writer whose sociological works have had a great impact on her society and the Arab world. This thesis sets out to trace how Sa'dawi's work as a doctor during the 1960s brought her into such close contact with the sufferings of women and girls in her society, that she set out to try and discover the reasons for such widespread oppression of her own sex. Each of Sa'dawi's factual works is treated separately here in chronological order. These works show Sa'dawi protesting against sexual and social abuses of women, against female circumcision and double standards of morality in her society. When she tries to expose the root causes of Arab women's oppression, she points the finger of blame at patriarchal society, economic pressures and misguided interpretations of psychology and religion. Sa'dawi is prevented from speaking out frankly against political or religious institutions because of the threat of censorship which carries with it the danger of imprisonment and persecution. Apart from a critical examination of her factual books, this thesis also contains a survey of her fictional works, for Sa'dawi has also achieved success in the field of literature with her short stories and novels. Her fiction frequently brings to the reader typical dilemmas facing women in Egyptian society. Again each work is discussed individually here. Since Sa'dawi is still very active as a writer, I have had to confine my thesis to covering her output up to 1986, which means that nineteen works are discussed in detail. The tremendous popularity of Sa'dawi and her written works rests largely on her commitment to helping her compatriots achieve balanced healthy lives from the psychological, physical and sexual dimensions, through frank discussions of highly controversial subjects. During the 1980s, Sa'dawi's fame has spread to the West where she is rightly regarded as the leading spokeswoman for Arab feminism.

description: Biomembranes consisting of two opposing phospholipid monolayers, which comprise the so-called lipid bilayer, are largely responsible for the dual solid-fluid behavior of individual cells and viruses. Quantifying the mechanical characteristics of biomembrane, including the dynamics of their in-plane fluidity, can provide insight not only into active or passive cell behaviors but also into vesicle design for drug delivery systems. Despite numerous studies on the mechanics of biomembranes, their dynamical viscoelastic properties have not yet been fully described. We thus quantify their viscoelasticity based on a two-dimensional (2D) fluid membrane model, and investigate this viscoelasticity under small amplitude oscillatory loadings in micron-scale membrane area. We use hydrodynamic equations of bilayer membranes, obtained by Onsager's variational principle, wherein the fluid membrane is assumed to be an almost planar bilayer membrane. Simulations are performed for a wide range of oscillatory frequencies $f$ and membrane tensions. Our numerical results show that as frequencies increase, membrane characteristics shift from an elastic-dominant to viscous-dominant state. Furthermore, such state transitions obtained with a 1-$μ$m-wide loading profile appear with frequencies between $O(f) = 10^1-10^2$ Hz, and almost independently of surface tensions. We discuss the formation mechanism of the viscous- or elastic-dominant transition based on relaxation rates that correspond to the eigenvalues of the dynamical matrix in the governing equations.
BIOLOGY AND HOST-INTERACTIONS OF NATURAL ENEMIES: Posters and Abstracts: FACTORS RESPONSIBLE FOR THE EXTINCTION OF CHRYSOMPHALUS AONIDUM (L.) FROM CITRUS ORCHARDS IN EGYPT

description: Ecological studies have shown that the black armoured scale, Chrysomphalus aonidum (L.), has four overlapping annual generations on navel orange trees under the conditions in Qalyubyia Governorate, Egypt. Five species of natural enemies were recorded on C. aonidum during the present work. The ectoparasitoid, Aphytis holoxanthus DeBach, was recorded for the first time from Egypt, and the other bioagents were three endoparasitoids: Aspidiotiphagus citrinus Craw., A. lounsburyi Berl. & Paoli and Habrolepis pascuorum Mercet and an entomogenous fungus, Cladosporium cladosporides (Fresen).

Recently, C. aonidum appears to have become extinct in citrus orchards in many localities in Egypt. It is considered that this is due to a combination of spray timing and the effects of these five bioagents. Since 1967, the Ministry of Agriculture in Egypt has recommended the use of summer sprays against this pest, instead of autumn and winter applications. Summer sprays are less harmful to these natural enemies, which are mainly effective against the winter and spring populations of C. aonidum.

description: The antimicrobial activity of the secretory materials associated with the test or wax covers of five scale insects was tested for Gram-positive and Gram-negative bacteria. The scale insects studied were the margarodid Icerya aegyptiaca (Douglas), the soft wax scale Ceroplastes rusci (Linnaeus) and three hard scales: Aonidiella aurantii (Maskell), Lepidosaphes beckii Nerwman and Parlatoria zyziphi (Lucas).

The Gram-positive bacteria found included Staphylococcus aureus and Streptococcus agalactia, while the Gram-negative bacteria included Escherichia coli, Pseudomonas aeruginosa and Corynebacterium pseudotuberculosis.

The results of these observations revealed that there was some highly significant antimicrobial activity associated the secretary materials of the diaspidids A. aurantii, L. beckii and P. zyziphus. The antimicrobial activity observed varied according to type of the pathogenic bacteria it was used against. Thus, the activity from all three species was effective against Staphylococcus aureus, but that of A. aurantii and P. zyziphus was less effective against Corynebacterium pseudotuberculosis.

title: Indonesian: Problems of development and use of a national language.

Publisher: name: SOAS University of London
Year: 1976

description: In this thesis we deal with the problems involved in the adoption of Malay as the language of national unity in Indonesia and its later development and use as the official state language of the Republic. In order to tackle the issues in a socio-linguistic perspective, we also undertake a brief survey of the study of language in general with a special, emphasis on discussions of the problems of language in society. Indonesian is not the mother tongue of the great majority of the population. As a matter of fact, the number of those who speak it as their native language is very small. However, the nationalist elite groups took drastic and revolutionary action to impose it on the entire Indonesian people. Although Malay had been in use as a lingua franca, especially in nationalist circles, it was the Japanese Military Government during the occupation period that decreed its wider employment and functions as a medium of official communication. Since Independence the language has been used as a medium of instruction not only in schools but also at the universities. The adoption of Indonesian as the sole official state language is characterised by apparent absence of linguistic conflicts, but language planners have been confronted with great problems. The relationship between Indonesian and the many regional languages has been clearly defined by government regulations. However, problems relating to this official arrangement are complicated and have not yet been solved. We have discussed here some aspects of the interaction of language, politics, religion, and ethnic affiliations. A great number of extra-linguistic factors have been instrumental in transforming linguistic situations in the archipelago. The historic adoption of Malay as the language of unity has had far-reaching implications.

title: Spatial and structural patterns of manufacturing industry in West Malaysia from 1957-1975 : A case study in industrial geography.
Creators: name: Santokh Singh, Mahinder
Publisher: name: SOAS University of London
Year: 1976

description: The theme of this thesis is an assessment of the Impact of the manufacturing sector on the national and regional economies of West Malaysia and an evaluation of the factors determining the spatial and structural patterns of manufacturing at the macro- and micro-levels. The industrial policy of the Government is viewed in the context of the economic problems confronting a newly independent nation characterised by an open dualistic economy. The district-level distribution and industrial structure that have emerged are evaluated. An analysis is made of the assumptions implicit in the plan for rapid industrial growth, that, spatially balanced development and an industrial structure conforming to the resource endowment can thereby be attained. Subsequent industrial strategy with its well- defined social and economic priorities is examined. Since the spatial organization and behaviour of industry is partly the result of the individual firm's decision-making and response to industrial policy, the entrepreneurs' motives for investing in manufacturing and the selection of sites are analysed within the framework of location theory. The industrial pattern that has resulted is evaluated. Changes in the industry-mix are noted. A centripetal pattern of industrial growth is revealed. The policy of achieving regional equality based on industrial decentralization is examined in the light of the major factors that determine Industrial location. The hypothesis that equitable distribution of manufacturing Industry involves the minimising of socio-economic differences between regions is tested at the district-level in a canonical correlation. A regional hierarchy is derived on the basis of socioeconomic structure and acquired industrial assistance. The relationship between industrial location and socio-economic structure is further examined in the analysis of commodity flow patterns. A dichotonous classification of commodity flows is derived. A system of regional and subregional production centres is revealed. Patterns of spatially mutual interactions and industrial linkages are derived from the analysis of commodity Interflows. Finally, alternative industrial policy measures and an industrial strategy based on an integrated system, of regional growth centres are examined.

description: We investigate the local fluctuations of filamentous actin (F-actin), with focus on the skeletal thin filament, using single-particle optical trapping interferometry. This experimental technique allows us to detect the Brownian motion of a tracer bead immersed in a complex fluid with nanometric resolution at the microsecond time-scale. The mean square displacement, loss modulus, and velocity autocorrelation function (VAF) of the trapped microprobes in the fluid follow power-law behaviors, whose exponents can be determined in the short-time/high-frequency regime along several decades. We obtain 7/8 subdiffusive power-law exponents for polystyrene depleted microtracers at low optical trapping forces. Microrheologically, the elastic modulus of these suspensions is observed to be constant up to the limit of high frequencies, confirming the origin of this subdiffusive exponent on the local longitudinal fluctuations of the polymers. Deviations from this value are measured and discussed in relation to the characteristic lengths scales of these F-actin networks and probes' properties, and also in connection with the different power-law exponents detected in the VAFs. Finally, we observe that the thin filament, composed by tropomyosin (Tm) and troponin (Tn) coupled to F-actin in the presence of Ca$^{2+}$, returns exponent values less dispersed than F-actin alone, which we interpret as a micro-measurement of the filament stabilization.

description: This study aims to develop a tax non-compliance prediction model in Tunisia using supervised machine learning algorithms. A data mining analysis was conducted following the Knowledge Discovery in Databases (KDD) process, utilizing a dataset of 20,930 labeled observations from 2013 to 2017, comprising 110 attributes. We employed supervised learning algorithms, including K-Nearest Neighbors, Decision Trees, Naïve Bayes, Gradient Boosting, and Random Forest, to identify the most accurate model. Notably, Random Forest outperformed the other algorithms, achieving a prediction accuracy of 83%. Furthermore, through a combined interpretation of feature importance derived from Random Forest, SHAP value analysis, and ANOVA, our findings provide tax auditors with insights into the most influential attributes for predicting tax non-compliance. This study holds significant practical implications by enhancing the efficiency of tax audits and supporting tax authorities in their efforts to combat tax non-compliance.

Let $\mathcal L$ and $\mathcal R$ denote the images of $U_q(\mathfrak{gl}_m)$ and $U_q(\mathfrak{gl}_n)$ in $\mathrm{End}(\mathcal P)$, respectively. We define a $q$-analogue of the algebra of polynomial-coefficient differential operators inside $\mathrm{End}(\mathcal P)$, henceforth denoted by $\mathcal{PD}$, and we prove that $\mathcal L\cap \mathcal{PD}$ and $\mathcal{R}\cap \mathcal{PD}$ are mutual centralizers inside $\mathcal{PD}$. Using this, we establish a new First Fundamental Theorem of invariant theory for $U_q(\mathfrak{gl}_n)$. We also compute explicit formulas in terms of $q$-determinants for generators of the intersections with $\mathcal{PD}$ of the images of the Cartan subalgebras of $U_q(\mathfrak{gl}_m)$ and $U_q(\mathfrak{gl}_n)$.

description: Ozone water, serving as a disinfectant, plays a significant role in the production of medical, food, and sanitation sectors. However, due to the instability of ozone water, it needs to be produced and used simultaneously in practical applications. It leads to a series of technical challenges. They include the lack of standard ozone water solutions. To address them, this study designs and constructs a new calibration system for online ozone water analyzers with controllable concentrations. This system has been successfully applied to the calibration of online ozone water analyzers from different manufacturers and models available. The concentration values of ozone water were verified using the chemical iodometric method. Calibration results showed that the indication error of the online ozone water analyzers ranged from 0.04 mg/L to 0.07 mg/L, the repeatability was between 0.0% and 4.1%, and the stability ranged from 2% to 9%. This study not only provides an effective solution for the calibration of online ozone water analyzers but also contributes to the standardization and quality control in related fields through the design and implementation of the system.
title: Politics and agrarian change among the plateau Tonga of Northern Rhodesia, c. 1924-63.
Creators: name: Dixon-Fyle, McSamuel
Publisher: name: SOAS University of London
Year: 1976

description: The Tonga Plateau was the main area of white settlement in Northern Rhodesia and in the 1920s many Africans there were moved into reserves on poor land which soon became overcrowded. At the same time, official restrictions were placed on the marketing of farm produce by the African population which supplied part of the Copperbelt market. Such grievances, together with settler pressure for closer union with Southern Rhodesia, prompted Africans in the area to form some of the earliest political associations in the territory. By the late 1940s, there was a small group of highly commercialised Tonga farmers. The Government tried to enlist the support of this elite with a scheme for 'Improved Farmers', but it was only partly successful and rules for land conservation antagonised the great mass of small scale African farmers. From the first, the plateau provided substantial support for the country's first nationalist party, the A.N.C. However, the party's leaders regarded the area, with its income from commercial farming, primarily as a source of funds and its organisation on the plateau was poor and several influential Africans declined to lend it any active assistance. The Improved Farmers, for instance, preferred their non-political Farmers Associations. This brought on them accusations of collaboration with white oppression which only increased their alienation. After the 1958 split in the A.N.C,'s leadership which led to the formation of U.N.I.P,, the A,N,C. came to be more closely identified with the Southern Province (and its political centre-point, the Tonga plateau), which area provided its most consistent support, U.N.I.P. lad the disadvantage of being rooted on the Copperbelt where few Tonga lived or worked. Besides, most of its leaders were long-standing urban residents and the Tonga had doubts about committing rural claims to such people. This lack of affinity with the Copperbelt partly ensured the A.N.C.' continued popularity on the Tonga plateau.

description: We present an explicit construction of a sequence of rate $1/2$ Wozencraft ensemble codes (over any fixed finite field $\mathbb{F}_q$) that achieve minimum distance $Ω(\sqrt{k})$ where $k$ is the message length. The coefficients of the Wozencraft ensemble codes are constructed using Sidon Sets and the cyclic structure of $\mathbb{F}_{q^{k}}$ where $k+1$ is prime with $q$ a primitive root modulo $k+1$. Assuming Artin's conjecture, there are infinitely many such $k$ for any prime power $q$.

description: We continue our analysis of open string field theory based on A-infinity-algebras obtained from Witten's theory by attaching stubs to the elementary vertex. Classical solutions of the new theory can be obtained from known analytic solutions in Witten's theory by applying a cohomomorphism. In a previous work, two such cohomomorphisms were found, one non-cyclic, obtained from the homological perturbation lemma and another cyclic one by geometric methods. Here we show that the two resulting maps are related by a combination of a gauge transformation and a term vanishing on-shell. In the second part of the paper we generalize the whole construction to non-BPZ even stubs, in particular sliver frame stubs. We discuss algebraic and geometric aspects and analyze the resulting conditions on the homotopy operator. Moreover, we explicitly calculate the first few orders of the new A-infinity-algebra solution for the tachyon vacuum in the sliver frame.
description: 33 pages; Version 2 contains a more detailed discussion of generalized stubs and the geometric and algebraic subleties and singularities that appear in the sliver frame
title: Characterization of the Cantonese dialect with special reference to its modified tones.

description: Chapter I - The Cantonese Dialect is characterized by its rich tonal system, which in this introductory chapter is compared with the tonal systems of four of the principal dialects of China, viz. the Peking, Shanghai, Hokkien and Hakka dialects. Chapter II - From historical and other records it is shown that Cantonese has a long history as a Chinese dialect, dating back to the 3rd century B.C., and that it has had continuous contacts with aboriginal dialects (chiefly Tai) up to fairly recent times (Sonq and Yuan). Chapter III - On account of its early establishment as a Chinese dialect, Cantonese possesses a number of arcthisms in its tone patterns as well as in its vocabulary and in structure. On the other hand, its contact with aboriginal dialects of the south has also affected its tonal system, vocabulary and, in some cases, even word-order. As far as the tonal system is concerned it has increased in richness of pattern, i.e. in variety of pitches and movements, owing to contact with rich aboriginal tonal systems. Its vocabulary has been likewise enriched, so that there are in current use in Cantonese today a large number of words not found in any other Chinese dialect (except in some cases in Hakka, which has been subjected to similar influences in the same province). A list of such 'peculiar' words is given. In addition, this thesis lists words which are common to both Cantonese and two Tai dialects (of Long jou ti and Shianqjou). In order to show up the marked, difference in structure between Cantonese and Northern Chinese dialects, a comparison is made between Cantonese and the National Language, i.e. the Peking dialect, including also comparison of the vocabulary. Chapter IV is devoted to the Cantonese tones in general. It starts with a critical survey of the contributions made by Western and Chinese scholars and sets out in particular the basic tone patterns and their development to the present stage of pitches and movements. Chapter V deals with the 'modified' tones, which may well be described as the most Interesting feature of the whole Cantonese tonal system. The 'modified' tones, changed from the 'basic' tones, serve to distinguish the 'particular' from the 'general'. They may also express a certain emotional attitude of the speaker or denote emphasis. Furthermore they may originate from omission of words (compensatory modification). It is contended that the modified tones have arisen from the coalescence of a noun and its diminutive suffix, a high-pitched 'i' (jrihx), which corresponds to and is etymologically identical with the suffix erl of the National Language, A topical list of current words which are generally spoken in the modified tones has been included.
title: The "Prabodhacandrodaya" of Krsnamisra: A critical edition of the text, with an introduction and essay on the development of allegorical literature in Sanskrit.
Creators: name: Dev, Jai

description: More than a century ago the late Mr. Brookhaus brought out an edition of Krsnamisra's Prabodhacandrodaya. Before he published his work, the drama had already been printed in India. Both these editions are of little value; as the former is based on the direct descendants of one codex and the latter is merely a print. Years passed but no serious attempts were made to prepare a critical edition of the drama. In the years 1908 and 1912 Dr. W.E.Clark planned to publish an edition, but for one reason or another his work was held up for long; consequently he altogether abandoned the idea of sending his work to the press. In 1936 K.Sambasiva Sastri of Trivandrum, the editor of the Trivandinan Sanskrit Series, published the text of the drama in that series. This edition, we are told, is based on MSS., but the editor gives only the names and whereabouts of their possessors and is, strangely enough, silent about the authenticity of the MSS. themselves. This edition too, is far from being satisfactory, as I have pointed out in my introduction. Since the drama's first appearance, the Prabodhacandrodaya has been translated into many modem European languages and has also been repeatedly printed, but no one has ever tried a critical hand on it. The other aspects of the drama, such as the philosophical thought, allegory, c., have remained unexplored. The present edition is the result of a careful study of not less than 17 MSG. and 5 printed works of the play. Further, in the introduction an attempt has been made to fix the author's date precisely and also to furnish the background for the development of Krsnainisra's philosophical and religious views. Moreover, the history of the allegorical literature from the Rgvedic period, wherein the allegory is in the making, to the end of the Classical period, where it appears in its bloom, has been summarised; a task never before attempted.
title: The notion of taboo with special reference to the Arabs.

description: This thesis is intended as a contribution to an anthropological study of the notion of tabee, with special reference to its manifestation, inter-connections and inter-relations with various social institutions among the Arabs. The primary aim is to formulate the ideas underlying the stystem in its many aspects. To show how ritual avoidances serve to establish or reflect certain fundamental social values to objects of important common interests, to events and even eventualities which crouse common concern and to situations and occasions which could not be controlled by technical means of the peoples concerned. Its immediate object is to demonstrate that the notion of taboo is not only of mere academic interest, but is also of emnirical, practical and secular importance. Ritual avoidances are considered as an integrate part of the mechanism by which the society maintains its existonce. It has been our method to cleave rather closely to primitive phenomena in analyising and examining the literature at hand. In the meantime we have carried the investigation through its successive stages to higher ethical and sophisticated manifestations of the notion in the hope of discovering the fundamental principles regulating the inatitution, and of determining the chief and general phases of its expression amon the Arabs, with the corresponding social and ritual values. For purposes of comparative study, we are partly concerned with ideas common both to the Arabs and various other simpler communities.

description: A circulant nut graph is a non-trivial simple graph whose adjacency matrix is a circulant matrix of nullity one such that its non-zero null space vectors have no zero elements. The study of circulant nut graphs was originally initiated by Bašić et al. [Art Discrete Appl. Math. 5(2) (2021) #P2.01], where a conjecture was made regarding the existence of all the possible pairs $(n, d)$ for which there exists a $d$-regular circulant nut graph of order $n$. Later on, it was proved by Damnjanović and Stevanović [Linear Algebra Appl. 633 (2022) 127-151] that for each odd $t \ge 3$ such that $t\not\equiv_{10}1$ and $t\not\equiv_{18}15$, the $4t$-regular circulant graph of order $n$ with the generator set $\{ 1, 2, 3, \ldots, 2t+1 \} \setminus \{t\})$ must necessarily be a nut graph for each even $n \ge 4t + 4$. In this paper, we extend these results by constructing two families of circulant nut graphs. The first family comprises the $4t$-regular circulant graphs of order $n$ which correspond to the generator sets $\{1, 2, \ldots, t-1\} \cup \left\{\frac{n}{4}, \frac{n}{4} + 1 \right\} \cup \left\{\frac{n}{2} - (t-1), \ldots, \frac{n}{2} - 2, \frac{n}{2} - 1 \right\}$, for each odd $t \in \mathbb{N}$ and $n \ge 4t + 4$ divisible by four. The second family consists of the $4t$-regular circulant graphs of order $n$ which correspond to the generator sets $\{1, 2, \ldots, t-1\} \cup \left\{\frac{n+2}{4}, \frac{n+6}{4} \right\} \cup \left\{\frac{n}{2} - (t-1), \ldots, \frac{n}{2} - 2, \frac{n}{2}-1 \right\}$, for each $t \in \mathbb{N}$ and $n \ge 4t + 6$ such that $n \equiv_{4} 2$. We prove that all of the graphs which belong to these families are indeed nut graphs, thereby fully resolving the $4t$-regular circulant nut graph order-degree existence problem whenever $t$ is odd and partially solving this problem for even values of $t$ as well.

description: Edge vision systems combining sensing and embedded processing promise low-latency, decentralized, and energy-efficient solutions that forgo reliance on the cloud. As opposed to conventional frame-based vision sensors, event-based cameras deliver a microsecond-scale temporal resolution with sparse information encoding, thereby outlining new opportunities for edge vision systems. However, mainstream algorithms for frame-based vision, which mostly rely on convolutional neural networks (CNNs), can hardly exploit the advantages of event-based vision as they are typically optimized for dense matrix-vector multiplications. While event-driven graph neural networks (GNNs) have recently emerged as a promising solution for sparse event-based vision, their irregular structure is a challenge that currently hinders the design of efficient hardware accelerators. In this paper, we propose EvGNN, the first event-driven GNN accelerator for low-footprint, ultra-low-latency, and high-accuracy edge vision with event-based cameras. It relies on three central ideas: (i) directed dynamic graphs exploiting single-hop nodes with edge-free storage, (ii) event queues for the efficient identification of local neighbors within a spatiotemporally decoupled search range, and (iii) a novel layer-parallel processing scheme allowing for a low-latency execution of multi-layer GNNs. We deployed EvGNN on a Xilinx KV260 Ultrascale+ MPSoC platform and benchmarked it on the N-CARS dataset for car recognition, demonstrating a classification accuracy of 87.8% and an average latency per event of 16$μ$s, thereby enabling real-time, microsecond-resolution event-based vision at the edge.
