Capybara and Tsubaki: Verifiable Random Functions from Group Actions and Isogenies
Authors: Lai Yi-Fu 
Published: October 2024

In this work, we introduce two post-quantum Verifiable Random Function (VRF) constructions based on abelian group actions and isogeny group actions with a twist. The former relies on the standard group action Decisional Diffie-Hellman (GA-DDH) assumption. VRFs serve as cryptographic tools allowing users to generate pseudorandom outputs along with publicly verifiable proofs. Moreover, the residual pseudorandomness of VRFs ensures the pseudorandomness of unrevealed inputs, even when multiple outputs and proofs are disclosed. Our work aims at addressing the growing demand for post-quantum VRFs, as existing constructions based on elliptic curve cryptography (ECC) or classical DDH-type assumptions are vulnerable to quantum threats.
In our contributions, our two VRF constructions, rooted in number-theoretic pseudorandom functions, are both simple and secure over the random oracle model. We introduce a new proof system for the factorization of group actions and set elements, serving as the proofs for our VRFs. The first proposal is based on the standard GA-DDH problem, and for its security proof, we introduce the (group action) master Decisional Diffie-Hellman problem over group actions, proving its equivalence to the standard GA-DDH problem. In the second construction, we leverage quadratic twists to enhance efficiency, reducing the key size and the proof sizes, expanding input size. The scheme is based on the square GA-DDH problem.
Moreover, we employ advanced techniques from the isogeny literature to optimize the proof size to 39KB and 34KB using CSIDH-512 without compromising VRF notions. The schemes feature fast evaluations but exhibit slower proof generation. To the best of our knowledge, these constructions represent the first two provably secure VRFs based on isogenies.

Published: October 2024

Our first objective is to enhance the capabilities of differential-neural distinguishers by applying more deep-learning techniques, focusing on handling more rounds and improving accuracy. Inspired by the Inception Block in GoogLeNet, we adopted a design that uses multiple parallel convolutional layers with varying kernel sizes before the residual block to capture multi-dimensional information. Additionally, we expanded the convolutional kernels in the residual blocks, enlarging the network's receptive field. In the case of Speck32/64, our efforts yield accuracy improvements in rounds 6, 7, and 8, enabling the successful training of a 9-round differential-neural distinguisher. As for Simon32/64, we developed a differential-neural distinguisher capable of effectively handling 12 rounds while achieving noteworthy accuracy enhancements in rounds 9, 10, and 11.
Additionally, we utilized neutral bits to ensure the required data distribution for launching a successful key recovery attack when using multiple-ciphertext pairs as input for the neural network. Meanwhile, we redefined the formula for time complexity based on the differences in prediction speeds of the distinguisher between a single-core CPU and a GPU. Combining these various advancements allows us to considerably reduce the time and data complexity of key recovery attacks on 13-round Speck32/64. Furthermore, we used knowledge distillation techniques to reduce the model size, accelerating the distinguisher's prediction speed and reducing the time complexity. In particular, we achieved a successful 14-round key recovery attack by exhaustively guessing a 1-round subkey. For Simon32/64, we accomplished a 17-round key recovery attack for the first time and reduced the time complexity of the 16-round key recovery attack.

Usage Sphere and Recognition Rate of Vulgarisms
Authors: Babayev Javid 
Published: October 2024

The article scrutinizes vulgarisms used in swear words, slangs, jargons, proverbs, sayings and idioms. Besides, the study made a survey on vulgarisms used in these lexical units by different age group respondents. While analyzing the article, it turned out that vulgarisms do not emerge as a result of anger or fury, so they can appear as a result of pampering or cuddling, too. After a rigid analysis, it became known that elderly respondents know more proverbs and sayings rich in vulgarity due to longer life experience while middle-aged people know more sexual slangs due to access to porn sites and adult videos. Teenagers do not know any proverbs or sayings containing vulgar words because of lack of life experience. After a profound investigation, it turned out that swear words host the most vulgarity while it is followed by slangs and jargons. Sexual slangs contain the second biggest vulgarity. Vulgarisms are sometimes euphemized in slangs or jargons while it is impossible in swear words.

Published: October 2024

Human beings live in a relationship with each other in human society and solve their problems through interaction. After years and centuries, due to climate change, their language and dialect change and words are added according to their new surroundings. Today, due to the advent of the scientific and technical revolution, climatic conditions will continuously increase and change. Climate change makes it evident that dialects have not persisted and that they alter when agricultural conditions in rural areas change, resulting in the usage of various words there. What was not used before, for the peviously Qalba in field the terms Qalba, Sarbani, Motani, and Ghazj were used but now the tractor is used instead. If a new technique is used in the field instead of the old manual tools, the economic structure will also change, and the relations among the residents will change until a new color and a new type appear in the construction and other parts of the environment, houses, and new sides as well. With it in a new way and a new color in a new language. In dialect, new terminology is created instead of the old terminology. Climate change over the years and centuries has caused changes in language and dialect.

Authors: Rahmani Hizbullah , Abid Mohammad Omar 
Published: October 2024

One of the most important global issues that face all countries is climate change. One of the nations most impacted by the effects of climate change is Afghanistan. The nation is more endangered due to its geographic location, delicate ecosystems, and socioeconomic difficulties. This article explores Afghanistan's vulnerability to climate change and highlights sustainable solutions to lessen its effects on the nation. Online surveys were used as part of the study, which comprised 136 lecturers and current students from several Afghani universities. The results showed that the main effects of climate change on Afghanistan are an increase in average temperature, more frequent and severe droughts, flooding and increased water scarcity, loss of food security and agricultural productivity, melting of glaciers and depletion of water resources, and an increase in the frequency and intensity of natural disasters (such as storms and landslides). The main sustainable ways to lessen the effects of climate change are to promote renewable energy sources (solar, wind, and hydro), implement water management and conservation practices, improve agricultural practices for increased resilience, improve infrastructure for disaster preparedness, reforest and conserve forests, educate and raise awareness about the impacts of climate change, empower communities, create accountable policy and decision-making processes, and develop national strategies for sustainable development.

Goya en Amérique. Voyage iconophage au pays sans peinture
Authors: Laliberté Bianca 
Published: October 2024

Le présent article corrobore l’hypothèse selon laquelle Francisco de Goya y Lucientes a su voir, à travers l’imaginaire du Nouveau Monde, l’apparition d’un problème d’ordre pictural. Qu’advient-il de la peinture dès lors qu’elle reconnaît l’ailleurs dont elle se sait absente ? Cette expérience de pensée nous est révélée par deux petits tableaux qu’il a peint à l’orée du XIXe siècle et portant des titres qui leur ont été donnés a posteriori : Cannibales montrant des restes humains (1810-1815 ?) et Cannibales préparant leurs victimes (1810-1815 ?). Par l’entremise d’une description rapprochée de leur matérialité et d’une analyse de leurs conditions de possibilité, cet article doit permettre d’extraire ces oeuvres du cadre tautologique à l’intérieur duquel leur fortune critique les a confinés. Goya n’y a pas peint des « sauvages » pour peindre des « sauvages »; il y révèle la logique interne de l’image picturale, à savoir une logique fondamentalement iconophage.
« La antropofagia te ha sentado muy bien » : de la dévoration chez Pedro Almodóvar
Authors: Bracco Diane 
Published: October 2024

En 2009, le cinéaste espagnol Pedro Almodóvar réalise le court-métrage La conseillère anthropophage (La concejala antropófaga), teaser humoristique du drame sorti la même année, Les Étreintes brisées (Los abrazos rotos). Le titre de ce film inscrit le personnage de Chon, extravagante conseillère municipale, dans une approche grotesque du corps que le présent article se propose d’analyser en prêtant une attention toute particulière aux déclinaisons littérales et métaphoriques de l’acte cannibale. Il s’agira tout autant d’appréhender le récit filmique comme unité autonome, dotée de ses mécanismes internes, que dans l’autophagie créative qui lie ce court-métrage au reste de la filmographie d’Almodóvar. L’étude des dynamiques de mise en scène et des réseaux d’interprétation tissés par les dialogues permettra de déterminer dans quelle mesure anthropophagie, sexe et politique se conjuguent pour forger une figure éminemment carnavalesque, mise au service d’une célébration de la matérialité du corps et d’une satire politique mordante.
Lire le cannibalisme dans L’Ingratitude de Ying Chen à la lumière du concept de « manger de l’homme » de Lu Xun
Authors: Song Jingyun 
Published: October 2024

L’Ingratitude de Ying Chen représente Yan-Zi, qui a l’impression d’être avalée par sa mère patriarcale. Mais le cannibalisme dans ce roman va au-delà de la relation mère-fille. Il partage les trois significations du concept de « manger de l’homme » dans l’oeuvre de Lu Xun, à savoir la pratique de manger la chair humaine, la privation du droit à la vie en raison des codes rituels ainsi que la négation de l’esprit libre individuel et du développement personnel. Dans une société où personne n’est dans un état libre et autonome, Yan-Zi est une révoltée contre ce système cannibale, comme le révolutionnaire Xia Yu dans Le médicament de Lu Xun. Par le cannibalisme, L’Ingratitude établit un dialogue avec Le médicament et dénonce l’héritage nocif des codes rituels de la doctrine confucéenne, qui entraîne la tragédie de Yan-Zi dans l’époque post-Mao en Chine. Le cadre fantastique marque l’originalité de l’oeuvre de Chen, qui emploie une « écriture oblique ». Bien que le cri à la fin des deux oeuvres apporte un petit souffle d’espoir, l’attitude pessimiste ressentie chez Lu Xun trouve un écho dans L’Ingratitude.

Published: October 2024

This study sought to identify the “Challenges in Managing School Funds for Heads of Secondary Schools in Kilolo District, Tanzania” through a mixed approach with the population of one District educational officer, six heads of schools, six school bursars and sixty-three secondary school teachers who obtained through purposive sampling and simple random techniques. Questionnaires and interviews used to collect data. Data analysed through thematic analysis and descriptive statistics with the aid of the Statistical Package for Social Sciences (SPSS) computer software. The findings found that heads of secondary schools faced numerous challenges such as inadequate funds from the government, inconsistencies disbursement of money from the government and bureaucracy. In addition, distance (remoteness of the schools), transport cost and time consumer when heads of schools needs procurement budgets approved from the District Educational Officer, poor support from the parents and some staff as well as denying school management training on financial management issues were among the challenges. Lastly, the findings found that training, workshops, provision of seminars will enhancing the heads of schools’ financial management literacy. Moreover, heads of schools should involve other staff members, school management team (SMT), and the use of educational financial guidelines as a source of knowledge and skills to manage schools’ fiscal resources. It also recommended that the heads of schools should adhere to the proper practices of financial management through monetary auditing. Likewise, Tanzania government should provide managerial training, workshops and seminars as the best strategies to diminish financial management challenges as well as introducing financial management courses in teachers’ colleges and universities prepare experts in the schools’ financial management activities.

Published: October 2024

Rainfed areas are crucial for India’s agriculture, covering 50% of the total farmland and contributing 40% of the country’s food production. In recent years, the adverse effects of climate change have been found to be exacerbating the complex problems in vulnerable rainfed areas. While climate change affects many aspects of the environment, its impact on water resources is often swift and apparent, with far-reaching consequences for ecosystems, human well-being, and sustainable development. In this context, water budgeting at watershed level and its management are crucial towards promotion of climate resilient agriculture in the rainfed ecosystems. Comprehensive assessment of water balance was attempted, estimating the demand from agriculture, domestic and livestock needs and availability of water in terms of groundwater recharge from different sources and effective surface water stored in an agricultural watershed falling in Siddipet district of Telangana state of India. It involved collection of data on population, land use, and estimating irrigation water needs for crops, humans and livestock, followed by inventorying surface storage structures. Further, water inflow, runoff, and groundwater recharge were calculated using standard methods. The water balance was then determined by subtracting total demand from total availability. The study revealed that the water balance improved significantly, shifting from a deficit (-1.18 ha-m) of pre-project phase to a surplus (+67.91 ha-m) during post-watershed development. Thus, this study revealed the effectiveness of soil and water conservation measures taken up as a part of watershed development project in enhancing groundwater recharge and effective surface water storage capacity leading to positive water balance. The study also evaluated the use of groundwater in terms of stage of development in the pre and post project scenarios. The study concluded that there is a need for controlling the over extraction of groundwater through crop diversification especially towards market driven, less water consuming high value vegetable cultivation based on water availability with active people participation along with awareness building, propagation of efficient water application (micro-irrigation) methods, group mode of irrigation, and conjunctive use of surface and groundwater, etc. for long-term water security in the watershed.
Bioengineering of Polyhydroxyalkanoates
Authors: Taguchi Seiichi 
Published: May 2017

Abstract
Establishment of a renewable whole‐cell catalyst platform for the production of biobased polymeric materials is an important area of synthetic biology. In this article, the fundamental properties of natural polyesters polyhydroxyalkanoates (PHAs), bearing a structural variety of over 160 monomeric constituents, are explained especially in terms of structure and function. Based on the strategic pathway engineering, successful bioengineering of PHAs is introduced together with several case studies on monomer‐supplying routes and PHA synthase enzyme alteration. Particularly, the effectiveness of engineering PHA synthesis–related enzymes is highly stressed. Important advances, such as the discovery of a “lactate‐polymerizing enzyme” (LPE) and the establishment of microbial platform for lactate‐based polyesters from renewable feedstock, are also presented. LPE‐based achievements for creating a new variety of incorporated unnatural monomers are expanded to 2‐hydroxybutyrate and glycolate units. This is a typical synthetic biology integrated by various biotechnological toolboxes to create novel polyesters, such as LA‐based polyesters and tailored‐made PHAs.

AbstractGround‐penetrating radar (GPR) is a well‐established geophysical terrestrial exploration method and has recently become one of the most promising for planetary subsurface exploration. Several future landing vehicles like EXOMARS, 2020 NASA ROVER, and Chang'e‐4, to mention a few, will host GPR. A GPR survey has been conducted on volcanic deposits on Mount Etna (Italy), considered a good analogue for Martian and Lunar volcanic terrains, to test a novel methodology for subsoil dielectric properties estimation. The stratigraphy of the volcanic deposits was investigated using 500 MHz and 1 GHz antennas in two different configurations: transverse electric and transverse magnetic. Sloping discontinuities have been used to estimate the loss tangents of the upper layer of such deposits by applying the amplitude‐decay and frequency shift methods and approximating the GPR transmitted signal by Gaussian and Ricker wavelets. The loss tangent values, estimated using these two methodologies, were compared and validated with those retrieved from time domain reflectometry measurements acquired along the radar profiles. The results show that the proposed analysis, together with typical GPR methods for the estimation of the real part of permittivity, can be successfully used to characterize the electrical properties of planetary subsurface and to define some constraints on its lithology of the subsurface.
