Use of iodine-125 episcleral brachytherapy treatment for circumscribed choroidal hemangioma in a pediatric patient
Authors: Benvenuto Franco , Guillen Soledad , Sgroi Mariana , Jimenez-Romo Carlos , Fandiño Adriana
Published: July 2024

The purpose of this report is to highlight the results of iodine-125 episcleral plaque radiotherapy for the treatment of circumscribed choroidal hemangiomas (CCHs) as an alternative to photodynamic therapy. CCH are rare benign vascular hamartomas without systemic associations. We herein describe the treatment of a case of a pediatric patient with CCH associated with an exudative retinal detachment. His treatment consisted of brachytherapy with a plaque loaded with 125 Iodine seeds with a target apex dose of 40 Gy. Preoperative visual acuity (VA) in the affected right eye was 20/800. After treatment and for 24 months of follow-up, the VA improved to 20/200, with no signs of radiation retinopathy or recurrence of subretinal fluid. The favorable visual results, resolution of exudative retinal detachments, and the low rate of side effects lead us to conclude that iodine-125 episcleral brachytherapy should be considered in large tumors, those with a subfoveal location or the presence of extensive subretinal fluid.

Published: July 2024

Automated face recognition plays a vital role in forensics. The most important evidence in the criminal investigation is the facial images captured from the crime scene, as they represent the identity of the people involved in crime. The role of law enforcement agencies is to identify the facial images from the suitable database. This information can be treated as strong evidence for the law enforcement agencies which becomes the most important evidence in global counter-terrorism initiatives. Contour of chin and cheek, distancebetween different features and shapes of facial components are some of the parameters considered by the forensic experts for manual facial identification process. This process is time consuming, and it is a tedious job. To address this issue, there is a need for developing an automated face recognition system for forensics. As a result, FaceNet – a framework for age variation facial digital images is discussed in this research work. Experiments are evaluated on CSA dataset with three age variations which provides a recognition accuracy of86.8% and performs better than the existing algorithms.

Leveraging markup to process narrative recipes
Authors: Flynn Peter
Published: July 2024

In two earlier papers I described the implementation of ‘℞’ (pronounced /ˈɹɛs.ɪ.pē/ ‘reSEEpay’), an XML/XSLT system for checking and reproducing structured cookery recipes. Since then, work has been ongoing: a) to refine the categories used in the metadata; b) to improve the implementation in CSS; and c) to extend the markup to narrative recipes encoded in other schemas. This paper describes the third of these, with a working implementation in TEI P5. The categorization task is out of scope for markup conferences, and is best discussed over a good dinner (the CSS is in scope but barely addressed here).
Invisible Fish: API Experimentation with InvisibleXML
Authors: Holstege Mary
Published: July 2024

Developing a simplifying textual interface over a complex set of components can be tricky. Here I use Invisible XML to isolate changes in the input language from the implementation, allowing for experimentation with wildly different approaches to the interface. An intentional, conlang approach to the experimentation is highlighted.
DTD (document type definition) declarations exposed in XSLT
Authors: Quin Liam
Published: July 2024

The XML specification defines a syntax for, and semantics for, a document type definition (DTD). An XML document can optionally reference a DTD, which it does by means of a document type declaration. The DTD may contain constraints on the elements that can be found in the XML document, and what attributes they may contain. It may also define entities, which associate names with strings or with external resources such as XML fragments or images. The constraints can be checked using a process termed validation.

The XML Data Model (XDM) does not expose declarations found in a document’s document type definition. As a result, XSLT stylesheets, XPath expressions, XQuery expressions, and anything else using the XDM, cannot reference them.

Sometimes one might want (or need) to access declarations from a DTD. The author in the past has written programs in procedural languages such as C or Perl in order to access such declarations.

This paper describes an XSLT stylesheet that parses DTD syntax and constructs a simple XML representation that can then be processed using XSLT or other XML-aware languages directly.

Some use cases and examples are given. The work is publicly available on gitlab.
Exploring User Acceptance of Autonomous Vehicles: Impact of Driver
and Vehicle Styles
Authors: Li Guanyu , Yu Wenlin , Chen Xizheng , Wang Wuhong , Guo Hongwei , Jiang Xiaobei
Published: July 2024

Autonomous vehicles (AVs) provide an effective solution for enhancing traffic
safety. In the last few years, there have been significant efforts and progress
in the development of AVs. However, the public acceptance has not fully kept up
with technological advancements. Public acceptance can restrict the growth of
AVs. This study focuses on investigating the acceptance and takeover behavior of
drivers when interacting with AVs of different styles in various scenarios.
Manual and autonomous driving experiments were designed based on the driving
simulation platform. To avoid subjective bias, principal component analysis
(PCA) and the Gaussian mixture model (GMM) were used to classify driving styles.
A total of 34 young participants (male-dominated) were recruited for this study.
And they were classified into three driving styles (aggressive, moderate, and
conservative). And AV styles were designed into three corresponding categories
according to the different driving behavior characteristics. This study reveals
that drivers generally prefer driving scenarios with lower risk levels. When
drivers perceive safety, they are more likely to adopt more efficient AVs.
Additionally, drivers tend to accept AVs that align better with their driving
styles. However, it is not found that more aggressive or conservative AVs have a
significant impact on their acceptance. Takeover behavior has been identified as
a significant mediator of acceptance, with the potential to influence drivers’
perceptions and attitudes. There is a marked decline in acceptance when takeover
behavior happens. The results show that regulating takeover behavior is
essential for the development of AVs that promote greater acceptance. And this
study contributes theoretical support to the development of adaptive AVs.
Optimized Homomorphic Evaluation of Boolean Functions
Authors: Bon Nicolas , Pointcheval David , Rivain Matthieu
Published: July 2024

We propose a new framework to homomorphically evaluate Boolean functions using the Torus Fully Homomorphic Encryption (TFHE) scheme. Compared to previous approaches focusing on Boolean gates, our technique can evaluate more complex Boolean functions with several inputs using a single bootstrapping. This allows us to greatly reduce the number of bootstrapping operations necessary to evaluate a Boolean circuit compared to previous works, thus achieving significant improvements in terms of performances. We define theoretically our approach which consists in adding an intermediate homomorphic layer between the plain Boolean space and the ciphertext space. This layer relies on so-called p-encodings embedding bits into Zp. We analyze the properties of these encodings to enable the evaluation of a given Boolean function and provide a deterministic algorithm (as well as an efficient heuristic) to find valid sets of encodings for a given function. We also propose a method to decompose any Boolean circuit into Boolean functions which are efficiently evaluable using our approach. We apply our framework to homomorphically evaluate various cryptographic primitives, and in particular the AES cipher. Our implementation results show significant improvements compared to the state of the art.
On the (Im)possibility of Preventing Differential Computation Analysis with Internal Encodings
Authors: Castelnovi Laurent , Houzelot Agathe
Published: July 2024

White-box cryptography aims at protecting implementations of cryptographic algorithms against a very powerful attacker who controls the execution environment. The first defensive brick traditionally embedded in such implementations consists of encodings, which are bijections supposed to conceal sensitive data manipulated by the white-box. Several previous works have sought to evaluate the relevance of encodings to protect white-box implementations against grey-box attacks such as Differential Computation Analysis (DCA). However, these works have been either probabilistic or partial in nature. In particular, while they showed that DCA succeeds with high probability against AES white-box implementations protected by random encodings, they did not refute the existence of a particular class of encodings that could prevent the attack. One could thus wonder if carefully crafting specific encodings instead of drawing random bijections could be a solution.This article bridges the gap between preceding research efforts and investigates this question. We first focus on the protection of the S-box output and we show that no 4-bit encoding can actually protect this sensitive value against side-channel attacks. We then argue that the use of random 8-bit encodings is both necessary and sufficient, but that this assertion holds exclusively for the S-box output. Indeed, while we define a class of 8-bit encodings that actually prevents a classical DCA targeting the MixColumns output, we also explain how to adapt this attack and exploit the correlation traces in order to defeat even these specific encodings. Our work thus rules out the existence of a set of practical encodings that could be used to protect an AES white-box implementation against DCA-like attacks.
Compress: Generate Small and Fast Masked Pipelined Circuits
Authors: Cassiers Gaëtan , Gigerl Barbara , Mangard Stefan , Momin Charles , Nagpal Rishub
Published: July 2024

Masking is an effective countermeasure against side-channel attacks. It replaces every logic gate in a computation by a gadget that performs the operation over secret sharings of the circuit’s variables. When masking is implemented in hardware, care should be taken to protect against leakage from glitches, which could otherwise undermine the security of masking. This is generally done by adding registers, which stop the propagation of glitches, but introduce additional latency and area cost. In masked pipeline circuits, a high latency further increases the area overheads of masking, due to the need for additional registers that synchronize signals between pipeline stages. In this work, we propose a technique to minimize the number of such pipeline registers, which relies on optimizing the scheduling of the computations across the pipeline stages. We release an implementation of this technique as an open-source tool, Compress. Further, we introduce other optimizations to deduplicate logic between gadgets, perform an optimal selection of masked gadgets, and introduce new gadgets with smaller area. Overall, our optimizations lead to circuits that improve the state-of-the art in area and achieve state-of-the-art latency. For example, a masked AES based on an S-box generated by Compress reduces latency by 19% and area by 27% over a state-of-the-art implementation, or, for the same latency, reduces area by 45%.
Low-Latency Masked Gadgets Robust against Physical Defaults with Application to Ascon
Authors: Cassiers Gaëtan , Standaert François-Xavier , Verhamme Corentin
Published: July 2024

Low-latency masked hardware implementations are known to be a difficult challenge. On the one hand, the propagation of glitches can falsify their independence assumption (that is required for security) and can only be stopped by registers. This implies that glitch-robust masked AND gates (maintaining a constant number of shares) require at least one cycle. On the other hand, Knichel and Moradi’s only known single-cycle multiplication gadget that ensures (composable) security against glitches for any number of shares requires additional care to maintain security against transition-based leakages. For example, it cannot be integrated in a single-cycle roundbased architecture which is a natural choice for low-latency implementations. In this paper, we therefore describe the first single-cycle masked multiplication gadget that is trivially composable and provides security against transitions and glitches, and prove its security in the robust probing model. We then analyze the interest of this new gadget for the secure implementation of the future lightweight cryptography standard Ascon, which has good potential for low-latency. We show that it directly leads to improvements for uniformly protected implementations (where all computations are masked). We also show that it is can be handy for integration in so-called leveled implementations (where only the key derivation and the tag generation are masked, which provides integrity with leakage in encryption and decryption and confidentiality with leakage in encryption only). Most importantly, we show that it is very attractive for implementations that we denote as multi-target, which can alternate between uniformly protected and leveled implementations, without latency overheads and at limited cost. We complete these findings by evaluating different protected implementations of Ascon, clarifying its hardware design space.
Determination of Cephalometric Norms of Sassouni’s Analysis in South Indian Ethnic Population: A Retrospective Study
Authors: Gopalakrishnan Umarevathi
Published: July 2024

Objective: Numerous cephalometric analyses have been proposed with the advent of cephalometric radiographs in orthodontics to ascertain the true skeletal and dental picture and correlate them with the clinical diagnosis. Sassouni’s analysis differs from other analyses that it provides detailed interaction between sagittal and vertical discrepancies. As the literature enlightens the existence of variability in the craniofacial morphology among different ethnic groups, cephalometric norms derived from standardized groups like Bolton samples and Ann Arbor samples cannot be considered normal for other populations. The aim of this study was to enforce the importance of deriving the cephalometric norms from the local population.

Methods: The sample comprised the retrospectively collected pre-treatment lateral cephalograms of 60 adults (25 males, 35 females) belonging to South Indian origin and was categorized into four groups based on inclusion and exclusion criteria. These cephalograms were traced, analysed and interpreted as per Sassouni’s analysis. The statistical evaluation was performed using Pearson’s chi square and spearman’s rho tests to assess the correlation between various morphological aspects of the craniofacial region including the palate, key ridge, mandible and their association with the sagittal and vertical dimensions.

Results: The ∑ shaped key ridge, the facial type III B with post archial and concave profile were more prevalent.

Conclusion: This study emphasizes the existence of variability in the facial characteristics of the South Indian and Mediterranean populations and the need to devise cephalometric norms for specific racial, ethnic and geographic origins.

This research investigated the perspectives of students on the implementation of group work in English learning process associated with five basic principles that facilitate group work, a theory by Johnson and Johnson (2009). The qualitative method was used to construct this research through the interview as the main technique and documentation to support the research data. This research was conducted in SMK Negeri 1 Marisa at the second-grade students. As a result, researcher found that (1). All participants showed a positive response associated with positive interdependence, in a sense of responsibility was emphasized. (2). The second basic principle that must exist is simultaneous interaction, which is related to the interactions of students, and the quality of their interactions. Related to this, there was a negative response from students on how the students were divided into groups. (3). Students gave quite positive responses related to the third basic principle, individual accountability, which is about the contribution of each student in the group. (4). The majority of students know how to act in groups, giving skills to students must be done and trained to be applied consistently. (5). Teachers need to consistently provide instructions, monitor the learning process, and evaluate it at the end of class. Investigating student perspectives regarding a strategy or a method implemented by the teacher in the teaching and learning process is something that needs to be done. By not ignoring students' opinions or perspectives, the teaching and learning process will take place more optimally.

Authors: Werimba Munyi Monica
Published: July 2024

This study investigated the influence of capacity building on the effectiveness of teachers in promoting a conducive learning environment in public secondary schools in Kenya. The study was carried out among secondary school teachers in Embu and Tharaka-Nithi Counties, Kenya. Utilizing a descriptive survey methodology, data were collected from a representative sample of 400 teachers through questionnaires capturing demographic information, participation in capacity building programs, and self-assessment of their effectiveness in maintaining a positive learning environment. The findings indicate that teachers who participated in four or more capacity building courses rated themselves higher in effectiveness compared to those with fewer or no courses attended. Key areas of effectiveness included fostering respectful student interactions and dignified discipline, while lower ratings were observed in displaying student work and engaging parents in behaviour discussions. Analysis of Variance results confirmed a significant positive effect of capacity building on teacher effectiveness, suggesting that continuous professional development is crucial for enhancing the learning environment. The study recommends expanding capacity building programs and focusing on diverse training areas for all teachers.

Cement manufacturing, distribution and use are associated with numerous environmental concerns that have a bearing to the business continuity and sustainability. Over time, the aspect of environmental conservation and management has become a critical business factor in the eyes of stakeholders and customers alike and thus influencing the performance of cement firms in Kenya. This study sought to establish the role of enviropreneurial marketing strategy to cement business performance in Kenya. The study adopted a pragmatism approach philosophy, acknowledging the real problems related to the industry practice and seeking to contribute practical solutions for future practice. Considering that only eight cement firms operate in Kenya, the study adopted the entire eight number firms as the sample size and sample population. Qualitative descriptive research design guided this research which purely relied on secondary data sources from previous research, published journals, information on companies’ website and published newsfeeds. The results revealed numerous efforts into enviropreneurial marketing strategies at varying degree from firm to firm. Further the results established a relationship between implementation of EM strategies to business performance, with Bamburi cement leading in EM efforts linked to its better performance in the market. Although the study acknowledged a number of challenges with EM strategies, there are revealed opportunities available for exploitation by cement firms in Kenya for improved performance. To achieve more realistic findings, the study recommends a future consideration of primary data sources for perceived reduction of biases imported from secondary data sources.

Published: July 2024

Alternate wetting and drying irrigation (AWD) is a promising technique that has been tried across Southeast Asia to reduce water consumption and methane emissions in irrigated rice cultivation. The study conducted in the upper Vietnamese Mekong Delta compared the effectiveness of plant growth, yield components, and yield under three different water application regimes: the treatments of community AWD (AWD_C), household individually (AWD_H), and continuous flooding (CF) with the expectation to explore the ability to use water effectively in rice cultivation. The results showed no significant difference in water use between the three treatments. However, there was a considerable difference in coefficient of variation value (CV); the CV value of the water column in the AWD_C (1.32%) was a significant difference from that of AWD_H (0.87%) and CF (0.89%). The mean chlorophyll content, the yield, and the weight of 1,000 grains of the AWD_H treatment were significantly higher than that of the other two treatments. In another aspect, the water productivity of the AWD_H treatment was the highest (0.66 kg/m3), a statistically significant difference compared to the AWD_C and CF (0.37; 0.33 kg/m3). In conclusion, the AWD_H shows efficiency in leaf chlorophyll content, 1,000-grain weight, yield, and water productivity. The AWD_C is inferior to the AWD_H due to the large variation of field elevation. It is noted that field elevation is critical to the technique’s success in being applied on a large scale.

The growing demand for agricultural products for food requirements caused the use of excessive inorganic chemical fertilisers, insecticides, fungicides, and pesticides for a quick and simple way to maximise and boost crop yield. This practice harmed food safety and caused the degradation of environmental, physical, and biological conditions. It has become alarming, and now is the time for a greener approach to increase agricultural output while minimising the use of inorganic chemical fertilisers. It was proven through many previous studies that using environmentally friendly biofertilisers has managed to increase crop yield while reducing the usage of chemical fertilisers. Plant growth-promoting rhizobacteria (PGPR) are mostly used in biofertiliser production because these types of microbes will enhance plant growth and yield by mobilising the available nutrients through several biological mechanisms, including fixation of atmospheric nitrogen, solubilisation, and mobilisation of phosphate and potassium, phytohormones production, disease suppression, and stress protection. Understanding their characteristics, biological mechanisms of action, and the nutritional and physical requirements for growth is important for successfully formulating and applying PGPR as a biofertiliser. The selection of the right PGPR with the desired characteristics, the ability to adapt to the environment, and the ideal formulation of the biofertiliser are the main criteria that should be emphasised when determining the success of biofertiliser. Knowledge and awareness regarding the use, benefits, and production of PGPR as a potential biofertiliser are important and should be explored to fulfil the crop’s nutritional requirements more economically and sustainably.

Published: July 2024

In the past decade, the cultivation of Job’s tears in Thailand has decreased. By contrast, consumption of Job’s tears in Thailand is still high as a functional food. Thus, it needs to be imported in large quantities from other nations. The objectives of this study were to determine the suitability of the different Job’s varieties of Job’s tears in Sa Kaeo province, East of Thailand and then to select a possible variety to evaluate its chemical properties. Then, the data will be used for the conservation and cultivation of Job’s tears in Thailand. Seven varieties of Job’s tears were collected from markets in Thailand from different sources such as Luang Phra Bang province in the Lao People’s Democratic Republic, Nong Khai, Loei and Chiang Rai provinces in Thailand. Firstly, 7 varieties of Job’s tears were grown and the plant growth characteristics were collected to evaluate their adaptability in Sa Kaeo province, Thailand. Secondly, the plant growth characteristics of 4 varieties of edible Job’s tears were recorded chemical properties such as their chemical composition, total phenolic content (TPC), total flavonoid compounds (TFC), DPPH radical scavenging assay, ABTS decolorization scavenging effect and potassium ferricyanide reducing power assay. The statistical data were analyzed by using the one-way analysis of variance (ANOVA) to determine the difference between varieties. The results showed that there are differences between the varieties in plant morphology and chemical properties. Seven Job’s tears plants were classified into 2 groups, an edible and an ornamental group. The Job’s tears seeds of the ornamental group could not be dehulled into kernels. AL1 to AL4 showed a good adaptability in their growth characteristics. AL4 in kernels had the proper CP at 17.78 % (p < 0.001) for use in a ruminant diet. AL2 had high plant height (157 cm), leaf areas (1,714 cm2) and a tiller number (4 - 6 tillers) which were good characteristics for forage utilization. While AL1 and AL4 had high TPC (46.15 and 24.55 mg GAE/g, respectively, p < 0.001) which showed a positive correlation with EE (p < 0.05). The kernels of AL1 and AL4 can be used as functional food.

The agricultural production of the Argentine Pampa is based on intensive cultures, and the most widely used insecticides correspond to cypermethrin (pyrethroid) and chlorpyrifos (organophosphate), among others. Sperm motility and fertility assessments are essential topics for biology and population dynamics studies on fish species. In this study the alterations of these endpoints after exposure to commercial formulation of both insecticides were used to analyze the effects on common carp sperm. After the in vitro exposure at nominal concentrations of 0.25, 0.5, 1, and 2 μg/L of cypermethrin, a significant reduction in motility in 0.5 μg/L concentrations was observed respect control group. The same nominal concentrations were tested for chlorpyrifos, and the same significative effect was detected at 2.0 μg/L. Fertilization rate was significantly reduced at concentrations from 0.5 μg/L cypermethrin exposure, and from 1.0 μg/L in the case of chlorpyrifos. Eggs LC50 / 24 h (95% confidence limit) exposed to cypermethrin was 0.57 μg/L (0.36 - 0.88), and exposed to chlorpyrifos was 2.45 μg/L (1.13-5.29). However, is still debatable how these insecticides impact on fish reproduction, using this in vitro scenario we found a clear reduction in sperm motility and fertility.

Published: July 2024

Tax payment has been a burden to business organizations, but a source of revenue to government. This study therefore, delved into the influence of government-imposed taxes on the profitability of firms, focusing on Nigerian Oil and Gas Companies. The research revealed that the coefficient of petroleum profit tax (PPT) exhibited a positive (11.28640) and statistically significant impact (P=0.0129 0.05). Similarly, the beta value of customs and excise duty (CED) displayed a positive (96.41566) and statistically significant impact (P=0.0013 0.05). On the other hand, the beta value of value-added tax (VAT) showed a negative effect (-706.1630) that was statistically significant (P=0.3117>0.05). In conclusion, this study demonstrated varying effects of government-imposed taxes on firms' profitability, particularly within Nigeria's oil and gas sector. While petroleum profit tax and customs and excise duty exerted positive and significant effects, value-added tax had a negative impact. Consequently, the study recommends a reduction in the value-added tax rate by the Nigerian government to facilitate the enhanced profitability of select oil and gas companies. Additionally, government should intensify its efforts in improving public infrastructural facilities like good access road, adequate electricity supply and security to assist private companies improve their profitability while reducing their expenses which will serve as an incentive and encouragement to enable them pay their taxes promptly and regularly.

This study aims to analyze the effect of banking stability, exchange rates, and external debt on economic growth in BRICS countries (Brazil, Russia, India, China, and South Africa) during the period 2011-2020. The data used in this study is panel data from five BRICS countries, obtained from the International Monetary Fund (IMF) and the World Bank. The method used is a panel data regression model using the Fixed Effect method. This model makes it possible to account for the fixed effects of time as well as the fixed effects of individual states in regression analysis. The results of the analysis show that banking stability has a significant negative influence on economic growth in BRICS countries. On the other hand, exchange rates and external debt have a significant positive impact on economic growth. These findings indicate that policies that promote banking stability, prudent exchange rate management, and effective use of external debt can support sustainable economic growth in BRICS countries. The results of the analysis show that banking stability has a significant negative influence on economic growth in BRICS countries. On the other hand, exchange rates and external debt have a significant positive impact on economic growth.
