Published: December 2024

Most current databases for bodily emotion expression are created in Western countries, resulting in culturally skewed representations. To address the obvious risk this bias poses to academic comprehension, we attempted to expand the current repertoire of human bodily emotions by recruiting Asian professional performers to wear whole-body suits with 57 retroreflective markers attached to major joints and body segments, and express seven basic emotions with whole-body movements in a motion-capture lab. For each emotion, actors performed three self-created scenarios that covered a broad range of real-life events to elicit the target emotion within 2–5 seconds. Subsequently, a separate group of participants was invited to judge the perceived emotional category from the extracted biological motions (point-light displays with 18 or 57 markers). The results demonstrated that the emotion discrimination accuracy was comparable to Western databases containing standardized performance scenarios. The results provide a significant step toward establishing a database using a novel emotional induction approach based on personalized scenarios. This database will contribute to a more comprehensive understanding of emotional expression across diverse contexts.

Аналізуючи дані по захворюванню кролів на стронгілоїдоз слідвідзначити, що його прижиттєва діагностика є утрудненою, оскількиклінічний прояв хвороби не має характерних клінічних ознак для даногозахворювання, а остаточний діагноз можна встановити лише залабораторної ідентифікації личинок гельмінтів. В Україні стронгілоїдознаінвазія кролів залишається стабільно високою протягом багатьох років іпотребує подальшого вивчення. Вона зустрічається переважно як складовазмішаних паразитозів. Найбільш часто асоціативні інвазії у кролівзустрічались у комбінаціях «еймеріоз+пасалуроз» (у 22,7 %),«еймеріоз+пасалуроз+цистицеркоз пізіформний» (у 4,9 %) і навіть у 5 кролів(0,45 %) була комбінація «еймеріоз+пасалуроз+цистицеркоз+фасціольоз».За результатами проведених нами досліджень встановлено, щостронгілоїдозна інвазія кролів найчастіше реєструється у виглядімікстінвазії (73,49 %) зі збудниками різних паразитарних хвороб.Стронгілоїдоз, як моноінвазію діагностували у 26,51 % від загальноїкількості уражених цим збудником тварин. З’ясовано, що найчастіше S.papillosus виявляли у складі двохкомпонентних мікстінвазій кролів (55,42 %).Рідше виявляли стронгілоїдесів у вигляді трьохкомпонентних мікстінвазій(18,07 %).Сезонна динаміка стронгілоїдозу кролів, екстенсивність таінтенсивність інвазії збільшуються у весняний період (54,81% і 166,95яєць/г), а саме з березня по травень з піком ЕІ та ІІ в травні (59,46% та219,81±24,68 яєць/г).Таким чином, результати показників стронгілоїдозної інвазії у кролівна території господарств Дніпропетровської області та морфометричнихпоказників S. papillosus суттєво доповнюють наукові дані попередніхдосліджень та полегшують диференційну діагностику захворювання.

Published: December 2024

The geotechnical properties of soils influence the stability of construction materials and civil engineering structures. This study investigated the geotechnical properties of soil for design and construction of foundation from Kpansia in Yenagoa, Bayelsa State, Nigeria using standard techniques. Results obtained show that the Atterberg limit results reveal that the liquid limit ranges from 73.2% to 94.8%, the plastic limit ranges from 31.2% to 48.6% while the plasticity index values range from 34.8% to 50.1%. The cohesive soils(clays) are highly plastic (CH) in the Unified Soil Classification System (USCS) designation. The natural moisture content ranges from 63.5% to 87.9%. The particle size distribution analysis reveals that the sand is fine to medium to coarse grained and in a medium dense state of compaction and based on its coefficient of uniformity and gradation classifies as poorly graded (SP) by the USCS designation. The moisture content of the sand ranges from 12.6% to 19.2% while the bulk unit weight ranges from 19.6KN/m3 to 20.3 KN/m3. The angle of shearing resistance ranges from 260 to 330. The result of the undrained shear strength of the clay ranges from 16Kpa and 19Kpa. The clay is very soft to soft and exhibit medium to high moisture content. The strength test result indicates a material of low undrained shear strength, the coefficient of consolidation, Cv of the clay soil samples varies between 1.40m2/year and 2.89 m2/year. The coefficient of volume compressibility,Mv,for the same materials varies between 0.088 m2/MN and 3.548 m2/MN, generally indicating clay layers of high to very high compressibility. Raft foundation is best suited for these weak, soft foundation materials.

The most prominent of the IRAS debris disk systems, α Lyrae (Vega), at a distance of 7.7 pc, has been observed by both the NIRCam and MIRI instruments on the James Webb Space Telescope. This paper describes NIRCam coronagraphic observations, which have achieved F444W contrast levels of 3 × 10−7 at 1″ (7.7 au), 1 × 10−7 at 2″ (15 au), and a few × 10−8 beyond 5″ (38 au), corresponding to masses of <3, 2, and 0.5 M
J for a system age of 700 Myr. Two F444W objects are identified in the outer MIRI debris disk, around 48 au. One of these is detected by MIRI and appears to be extended with a spectral energy distribution similar to those of distant extragalactic sources. The second one also appears extended in the NIRCam data suggestive of an extragalactic nature. The NIRCam limits within the inner disk (1″–10″) correspond to model-dependent masses of 2–3 M
J. K. Y. L. Su et al. argue that planets larger than 0.3 M
J would disrupt the smooth disk structure seen at MIRI wavelengths. Eight additional objects are found within 60″ of Vega, but none have astrometric properties or colors consistent with planet candidates. These observations reach a level consistent with expected Jeans mass limits. Deeper observations achieving contrast levels < 10−8 outside of ∼4″ and reaching masses below that of Saturn are possible, but may not reveal a large population of new objects.

SPT2349−56 is a protocluster discovered in the 2500 deg2 South Pole Telescope (SPT) survey. In this paper, we study the kinematics of the galaxies found in the core of SPT2349−56 using high-resolution (1.55 kpc spatial resolution at z = 4.303) redshifted [C ii] 158 μm data. Using the publicly available code
3D

BAROLO, we analyze the seven far-infrared brightest galaxies within the protocluster core. Based on conventional definitions for the detection of rotating disks, we classify six sources to be rotating disks in an actively star-forming protocluster environment, with weighted mean V
rot/σ
disp = 4.5 ± 1.3. The weighted mean rotation velocity (V
ro
t) and velocity dispersion (σ
disp) for the sample are 357.1 ± 114.7 km s−1 and 43.5 ± 23.5 km s−1, respectively. We also assess the disk stability of the galaxies and find a mean Toomre parameter of Q
T = 0.9 ± 0.3. The galaxies show a mild positive correlation between disk stability and dynamical support. Using the position–velocity maps, we find that five sources further classify as disturbed disks, and one classifies as a strictly rotating disk. Our sample joins several observations at similar redshift with high V/σ values, with the exception that they are morphologically disturbed, kinematically rotating, and interacting galaxies in an extreme protocluster environment.

Active galactic nuclei (AGN) are the signposts of black hole growth, and likely play an important role in galaxy evolution. An outstanding question is whether AGN of different spectral types indicate different evolutionary stages in the coevolution of black holes and galaxies. We present the angular correlation function between an AGN sample selected from Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) optical photometry and Wide-field Infrared Survey Explorer mid-IR photometry and a luminous red galaxy (LRG) sample from HSC-SSP. We investigate AGN clustering strength as a function of luminosity and spectral features across three independent HSC fields totaling ∼600 deg2, for z ∈ 0.6 −1.2 and AGN with L
6 μm > 3 × 1044 erg s−1. There are ∼28,500 AGN and ∼1.5 million LRGs in our primary analysis. We determine the average halo mass for the full AGN sample (M

h
≈ 1012.9
h

⊙), and note that it does not evolve significantly as a function of redshift (over this narrow range) or luminosity. We find that, on average, unobscured AGN (M

⊙), at 5σ statistical significance using 1D uncertainties, and at 3σ using the full covariance matrix, suggesting a physical difference between unobscured and obscured AGN, beyond the line-of-sight viewing angle. Furthermore, we find evidence for a halo mass dependence on reddening level within the Type I AGN population, which could support the existence of a dust-obscured phase. However, we also find that quite small systematic shifts in the redshift distributions of the AGN sample could explain current and previously observed differences in M

Supernova Shocks in Molecular Clouds: Shocks Driven into Dense Cores in IC 443 and 3C 391

Published: December 2024

Supernova shocks into dense molecular cores in IC 443 (clumps B, C, and G) and 3C 391 were observed using the Stratospheric Observatory for Infrared Astronomy and complemented by archival data from the Herschel Space Observatory. The pure rotational transitions 0–0 S(1) and S(5) of H2, and the ground-state 110–101 transition of H2O, are all broadened, arising from molecules that survive the passage of the shock front. Theoretical models from the Paris–Durham shock code were analyzed to generate velocity profiles that approximately match the observations. The observations can be fit with two shock conditions, which approximate the range of densities in the preshock molecular cloud. The width and brightness of the S(5) lines require shocks into gas with a density of order 2000 cm−3, into which the IC 443 blast wave drives shocks with speed 60 km s−1. The brightness and narrower width of the S(1) lines requires different shocks, into gas with density of order 105 cm−3, with shock speeds of 10 km s−1. The H2O velocity distribution is also consistent with these shocks. The existence of shocks into dense gas shows that the bright shocked clumps in IC 443 were prestellar cores. It is unlikely that they will form stars soon after the passage of the shock front, given the input of kinetic and thermal energy from the shocks.
Intra-specific diversity and adaptation modify regime shifts dynamics under environmental change
Authors: Imbert Thomas , Poggiale Jean-Christophe , Gauduchon Mathias
Published: December 2024

Environmental changes are a growing concern, as they exert pressures on ecosystems. In some cases, such changes lead to shifts in ecosystem structure. However, species can adapt to changes through evolution, and it is unclear how evolution interacts with regime shifts, which restricts ecosystem management strategies. Here, we used a model of prey population with evolution and intra-specific trait diversity, and simulated regime shifts through changes in predation pressure. We then explored interactions between evolution, diversity, and shifts in population density. Evolution induced delayed or early regime shifts, and altered the recovery of populations. Such changes depended on the relative speed of evolution and change of predation pressure, as well as on the initial state of the population. Evolution also influenced population resilience, which was important when considering strong environmental variability. For instance, storms can spontaneously increase mortality and induce shifts. Furthermore, environmental variability induced even higher mortality if the phenotypic diversity of populations is large. Some phenotypes were more vulnerable to environmental changes, and such increases in mortality favor shifts to decreases in density. Thus, population management needs to consider diversity, evolution, and environmental change altogether to better anticipate regime shifts on eco-evolutionary time scales. Here, evolution and diversity showed complex interactions with population shift dynamics. Investigating the influence of higher diversity levels, such as diversity at a community level, should be another step towards anticipating changes in ecosystems and communities.
Homogenization of attractors to reaction–diffusion equations in domains with rapidly oscillating boundary: Critical case

Published: December 2024

In the present paper, reaction–diffusion systems (RD-systems) with rapidly oscillating coefficients and righthand sides in equations and in boundary conditions were considered in domains with locally periodic oscillating (wavering) boundary. We proved a weak convergence of the trajectory attractors of the given systems to the trajectory attractors of the limit (homogenized) RD-systems in domain independent of the small parameter, characterizing the oscillation rate. We consider the critical case in which the type of boundary condition was preserved. For this aim, we used the approach of Chepyzhov and Vishik concerning trajectory attractors of evolutionary equations. Also, we applied the homogenization (averaging) method and asymptotic analysis to derive the limit (averaged) system and to prove the convergence. Defining the appropriate axillary functional spaces with weak topology, we proved the existence of trajectory attractors for these systems. Then, we formulated the main theorem and proved it with the help of auxiliary lemmata.
RETRACTED ARTICLE: Decay estimates for the wave equation with partial boundary memory damping
Authors: Jin Kun-Peng , Liu Can
Published: December 2024

In this paper, we discuss the wave equation with boundary memory damping. Notably, the system only involves the partial boundary memory damping, with no other types of damping (such as frictional damping) applied to the boundaries or the interior. Previous research on such boundary damping problems has focused on boundary friction damping terms or internal damping terms. By using the properties of positive definite kernels, high-order energy methods, and multiplier techniques, we demonstrate that the integrability of system energy is achieved if the kernel function is monotonically integrable, which indicates that the solution energy decays at a rate of at least $ t^{-1} $. This finding reveals that partial boundary memory damping alone is sufficient to generate a complete decay mechanism without additional, thereby improving upon related results.
The Impact of Socio-Demographic Factors on the Use of Digital Learning Platforms and Forms of Learning by Generation Z Engineering Students
Authors: Berková Kateřina , Kubišová Andrea , Krpálková Krelová Katarína , Krpálek Pavel , Holečková Lenka
Published: December 2024

The demands on higher education are increasing with the rise of generation Z. The emphasis is put on dynamism, a fast pace of teaching, dividing teaching into smaller blocks, alternating methods, digital tools, and using the possibilities of modern technologies. Educators must continually innovate and build improved pedagogical strategies in engineering to support student learning. Therefore, it is necessary to constantly innovate and build more sophisticated educational strategies with an impact on direct teaching and to support student learning. The aim of this study is to investigate the influence of socio-demographic factors (gender, field of study, and form of study) on the use of digital platforms and preferred forms of learning among Czech generation Z university students. The study emphasizes the preferences of generation Z students in engineering degree programs compared to students in economics and humanities degree programs. This comparison results from differences in teaching delivery and learning styles or methods. Hypotheses are tested using the Chi-square test and Cramer’s V. Engineering students prefer videos with a deeper explanation of the problem, and they mainly use the MS Teams platform and platforms allowing formative assessment and expression of their attitude. The practical implication of the study for education is mainly the identification of the basic characteristics of an appropriate educational strategy reflecting the needs of generation Z representatives. The article discusses the use of experimental and laboratory teaching. Similarly, as in the Czech Republic, also in the international environment, the project method, e-learning, gamification, Massive Open Online Courses (MOOCs), or videos in microlearning format are used in working with generation Z in engineering education. The study highlights the need to explore the influence of social factors and gamification elements in learning.

The role of women in achieving the Sustainable Development Goals by 2030 has been widely highlighted both locally and internationally. While the low participation of women in the labour force compared to men is a global concern, the low number of women leaders in various institutions and organisations in developed and developing countries is notable. This unit examines the changing role of women in society and education in different global contexts. The unit also examines the barriers women face in participating in organisations and sustaining their presence as leaders in light of feminist theories. Emphasising the growing importance of women's leadership and the benefits of their active contribution to educational leadership, this unit addresses the challenges women face in their professions from an international perspective. Sustainable strategies for women's leadership in education are discussed at the end of the unit.

Published: December 2024

This study examines how decentralized financial (DeFi) technologies could enhance financial inclusion and autonomy for India's indigenous communities by increasing their access to capital and financial services. Through surveys and interviews with key stakeholders, including community leaders, fintech experts, and policymakers, the research evaluates barriers to DeFi adoption, such as digital literacy, tech access, and regulatory limitations. It also explores DeFi's alignment with traditional practices via case studies showing how DeFi projects boost local entrepreneurship, market access, and economic growth. Global examples provide comparative insights into success factors and challenges, offering lessons for scaling DeFi in rural and semi-urban indigenous areas. The paper ends with policy recommendations to develop infrastructure and regulations essential for robust DeFi ecosystems, aiming to create a more inclusive financial landscape that integrates indigenous economies into India's broader economic structure

Published: December 2024

The research investigates the effect of natural resources on climate change and the role inclusive finance plays in the natural resource-climate change nexus among thirty-two resource-rich African countries from 2004-2022. Data acquired from World Development Indicator Database and International Monetary Fund Database are analyzed using the heterogeneous dynamic Pooled Mean Group estimation technique. The research demonstrates that natural resources negatively but insignificantly impact climate change. Also, inclusive finance negatively but significantly impacts climate change in the long run. Finally, the interactive effect of natural resource and climate change have a negative and significant effect on climate change among the selected resource-rich African nations. The findings show that inclusive finance is very key in enabling resource-rich African countries to adapt sufficiently to and fight climate change. From these findings, the study recommends priority toward the development of inclusive financial systems by policymakers in resource-rich countries in Africa.

The present paper deals with the effect of three different raster orientation angles and a 0.5 wt.% dope of graphene on the tensile strength of samples made of acrylonitrile butadiene styrene as per ASTM-D638 standard. It is interesting to observe that the samples prepared with a raster orientation of 0° degree with respect to the longitudinal axis showed highest tensile strength followed by 45° and 90°. The similar trend is also observed with the samples doped with 0.5 wt.% graphene although the tensile strength is observed to increase by 50% than that of the samples of plain ABS. In order to explore the effect of strain rate on tensile strength of plain and doped ABS specimens, the experiments were also performed at a cross head speed of 300mm/min and found that the strain rate increases the tensile strength by 2 to 3 times depending upon the raster orientation angle during fabrication of the samples.

The effectiveness of community-led total sanitation cadre intervention in improving stunting knowledge and behavior
Authors: Syam Dedi Mahyudin , Bungawati Andi
Published: December 2024

The prevalence of stunting remains high in Central Sulawesi Province, Indonesia. Poor sanitation is a significant risk factor for stunting, and community-based interventions such as Community-Led Total Sanitation (CLTS) show promise in addressing this issue. Despite the government’s multi-sectoral and integrated approach, encompassing both specific and sensitive nutrition interventions, the problem of stunting persists. This study aimed to assess the effectiveness of cadre-led interventions in improving community knowledge and behavior related to CLTS as a means of stunting prevention. A quasi-experimental, non-randomized design was used, with proportional stratified random sampling applied to a population of 332, resulting in a sample size of 182 individuals. Data collection was conducted from July to September 2023. The intervention involved CLTS cadres delivering counseling and triggering activities to mothers of stunted children. Knowledge and behavior regarding the five pillars of CLTS were measured as the dependent variables using a CLTS questionnaire with a scoring system. Data analysis was performed using SPSS version 22.0, specifically employing the independent-sample t-test with a significance threshold of p<0.05. Results indicated a significant increase in knowledge across the five pillars of CLTS (p=0.000), as well as a significant improvement in behavior concerning handwashing with soap, drinking water, food management, and household wastewater management (p=0.000). The findings suggest that cadres play an effective role in enhancing community knowledge and behavior regarding CLTS, contributing to stunting prevention efforts.
Posttreatment sexual dysfunction in cervical cancer survivors: A narrator review
Authors: Mahajan Divya
Published: December 2024

Cervical cancer is a significant public health issue in India, with 122,844 women diagnosed and 67,477 deaths annually. India has the highest age-standardized incidence of cervical cancer in South Asia. Cervical cancer treatment include surgery, radiotherapy via EBRT and ICRT, chemotherapy this cause phycological and sexual distress among the cancer survivors. Sexual dysfunction is a common issue faced by women after cervical cancer treatment, and it can have a significant impact on their quality of life. Cancer survivor who are at risk of developing sexual dysfunction should be educated regarding the sexual activity and individual therapies to prevent post treatment complication.. An integrated team of cancer therapists, psychologists, nurses and sexologists should be available in treatment centre in order to increase their sexual function quality. Sexual rehabilitation is an important aspect of survivors of cervix and other gynaecological cancer. To address this gap in knowledge, the article suggests conducting randomized studies with larger numbers of sexually active patients, comprehensive assessments of sexual problems, and different treatment approaches.

Published: December 2024

Although not common, general anesthesia may be required in section cesarean due to a maternal contraindication. Opioids are typically utilized as analgetic in general anesthesia. It is customary to restrict the use of opioids and fetal narcotic exposure during cesarean deliveries due to the side effects on the mother and the fetus. We present a successful case of multimodal opioid-free general anesthesia for cesarean birth in patients with help syndrome.
Nuclear protein in testis midline carcinoma in the head-and-neck area
Authors: Swain Santosh Kumar
Published: December 2024

Nuclear protein in testis (NUT) midline carcinoma (NMC) is an uncommon and lethal cancer of squamous cell lineage in the midline region of the body. NMC mostly affects the body’s midline regions, including the thorax, head, and neck. However, a few additional locations, including the kidney and pancreas, are also affected, albeit rarely. Involvement of the head-and-neck area often poses a challenge for the management of this tumor because of its rapid spread to skull bases, brain, and other vital structures. It can affect patients with a wide range of ages including pediatric age group. NMCs are not classified on the basis of the tissue/site of origin as with most solid tumors but are rather considered genetically. Squamous cell carcinomas make up the majority of NMCs, and they can only be identified by molecular or immunohistochemical testing. Any nonsmoking individuals with poorly differentiated squamous cell carcinoma should be evaluated for NMC. Histopathological analysis and immunohistochemistry using a highly specific antibody are frequently used to make the diagnosis of NMC. For patients with NMC, there are currently no standard-of-care therapy options available. However, there are not many cutting-edge therapies being researched that explicitly address the distinct tumorigenic pathway. The purpose of this review is to increase awareness of this underdiagnosed head-and-neck cancer and to provide awarness among clinicians for getting accurate diagnosis and an early start on treatment.

The clustering flower approach markedly improves learners' conceptual understanding, motivation, engagement, and critical thinking, evidenced by considerable advancements in several educational measures. This action research sought to enhance the conceptual comprehension in English among Grade 8 pupils. The research utilized a classroom-based action research methodology, recruiting 33 students by purposive sampling from a public secondary school in Ozamiz City during the 2023-2024 academic year. A researcher-developed pre-test and post-test were utilized for data collection, with analysis involving the calculation of the mean and standard deviation, as well as the execution of a t-test. The study employed statistical tools like frequency, percentage, mean, standard deviation, and t-test. Thematic analysis was conducted via HyperResearch to identify prevalent and emerging themes. Prior to the use of clustering techniques, the students' conceptual grasp was inadequate; however, following the intervention, their performance improved to a satisfactory level. The integration of the clustered flower method is an effective tool for improving students' conceptual comprehension in English.

Zero-knowledge proof (ZKP) is an attractive cryptographic paradigm that allows a party to prove the correctness of a given statement without revealing any additional information. It offers both computation integrity and privacy, witnessing many celebrated deployments, such as computation outsourcing and cryptocurrencies. Recent general-purpose ZKP schemes, e.g., zero-knowledge succinct non-interactive argument of knowledge (zk-SNARK), suffer from time-consuming proof generation, which is mainly bottlenecked by the large-scale number theoretic transformation (NTT) and multi-scalar point multiplication (MSM). To boost its wide application, great interest has been shown in expediting the proof generation on various platforms like GPU, FPGA and ASIC.So far as we know, current works on the hardware designs for ZKP employ two separated data-paths for NTT and MSM, overlooking the potential of resource reusage. In this work, we particularly explore the feasibility and profit of implementing both NTT and MSM with a unified and high-performance hardware architecture. For the crucial operator design, we propose a dual-precision, load-balanced and fully-pipelined Montgomery multiplier (LBFP MM) by introducing the new mixed-radix technique and improving the prior quotient-decoupled strategy. Collectively, we also integrate orthogonal ideas to further enhance the performance of LBFP MM, including the customized constant multiplication, truncated LSB/MSB multiplication/addition and Karatsuba technique. On top of that, we present the unified, scalable and highperformance hardware architecture that conducts both NTT and MSM in a versatile pipelined execution mechanism, intensively sharing the common computation and memory resource. The proposed accelerator manages to overlap the on-chip memory computation with off-chip memory access, considerably reducing the overall cycle counts for NTT and MSM.We showcase the implementation of modular multiplier and overall architecture on the BLS12-381 elliptic curve for zk-SNARK. Extensive experiments are carried out under TSMC 28nm synthesis and similar simulation set, which demonstrate impressive improvements: (1) the proposed LBFP MM obtains 1.8x speed-up and 1.3x less area cost versus the state-of-the-art design; (2) the unified accelerator achieves 12.1x and 5.8x acceleration for NTT and MSM while also consumes 4.3x lower overall on-chip area overhead, when compared to the most related and advanced work PipeZK.

Published: December 2024

Masking has emerged as a widely adopted countermeasure against side-channel attacks. However, the implementation of masking schemes faces several challenges, including hardware area, latency and the overhead associated with fresh randomness generation. To eliminate the implementation cost caused by fresh randomness, Shahmirzadi et al. introduced a methodology for constructing 2-share first-order masking schemes without randomness at CHES 2021. In this work, we extend Shahmirzadi et al.’s method to find masked implementations for more S-boxes and further reduce the hardware overhead. We propose the concept of a non-linear compression layer, a comprehensive share assignment strategy based on a linear compression layer, and corresponding optimization techniques. Based on these techniques, we construct the first randomness-free first-order masking schemes for the PRINCE S-box and its inverse, reduce the hardware overhead of masking schemes for multiple S-boxes, and design new masking-friendly S-boxes. Particularly for the SKINNY S-box, the reduction is 21% and 15% in area and power consumption, respectively. To validate the security of masked implementations, we not only employ the automated tools SILVER and PROLEAD but also conduct FPGA-based experiments.
Full Key-Recovery Cubic-Time Template Attack on Classic McEliece Decapsulation

Published: December 2024

Classic McEliece is one of the three code-based candidates in the fourth round of the NIST post-quantum cryptography standardization process in the Key Encapsulation Mechanism category. As such, its decapsulation algorithm is used to recover the session key associated with a ciphertext using the private key. In this article, we propose a new side-channel attack on the syndrome computation in the decapsulation algorithm that recovers the private key, which consists of the private Goppa polynomial g and the permuted support L. The attack relies on both practical aspects and theoretical contributions, namely that the side-channel distinguisher can accurately discriminate elements of the permuted support L, while relying only on a standard noisy Hamming weight leakage assumption and that there exists a cubic-time algorithm that uses this information to recover the private Goppa polynomial g. Compared with previous work targeting the Classic McEliece private key, this drastically improves both on the assumptions made in the attacker model and on the overall efficiency of the key-recovery algorithm. We have carried out the attack in practice on a microcontroller target running the reference implementation of Classic McEliece, and make the full attack source code available.

Published: December 2024

In recent years, the limits of electromagnetic side-channel attacks have been significantly expanded. However, while there is a growing literature on increasing attack distance or performance, the discovery of new phenomenons about compromising electromagnetic emanations remains limited.In this work, we identify a novel form of modulation produced by unintentional electromagnetic emanations: phase-modulated emanations. This observation allows us to extract a side-channel leakage that can be exploited to reveal secret cryptographic material. We introduce a technique allowing us to exploit this side-channel in order to perform a full AES key recovery, using cheap and common hardware equipment like a software-defined radio (SDR). Moreover, we demonstrate that the exploitation of this new phase leakage can be combined with traditional amplitude leakage to significantly increase attack performance. While investigating the underlying phenomenon causing this unintentional modulation, we identified several prior works that have approached similar exploitation – without being aware of each other. Creating a bridge between older and recent work, we unveil the relationship between digital jitter and signal phase shift in the context of side-channel attacks and fill the gap between prior works from various research fields.

Until the goal of complete transition to renewable energy sources is achieved, care must be taken to meet current energy needs. Of the total electricity produced in the Republic of Serbia in 2022, more than 68% will be energy obtained in thermal power plants. This data clearly indicates the necessity of preserving and extending the life of existing energy plants, which also include mining machines for unearthing the so-called overburden and coal (excavators) working in surface mines. The paper presents the modernization of the drive of the working element of the bucket-chain excavator.
