Ultrahigh Electrochemical Performance Co4Sb11.2Sn0.02Te0.78 for Supercapacitor Cathode
Authors: Li Zhi Peng , He Xin Rui , Chen Xing , Niu Yi , Jiang Jing
Published: December 2023

Due to the high theoretical specific capacitance, the skutterudite CoSb3 alloy is a promising supercapacitor electrode material. However, the lack of oxidative active sites and intrinsic poor electrical conductivity greatly hinder its application prospects. Here, we constructed a CoSb3 alloy compound co-doped with Sn and Te (Co4Sb11.2Sn0.02Te0.78) by a melting and annealing method. As the electrode material of the supercapacitor, Co4Sb11.2Sn0.02Te0.78 cathode shows an ultrahigh specific capacity of 1357 mAh g-1 (at 1 A g-1). Even when the current density is increased to 20 A g-1, 42% of the initial capacity is maintained. The advantageous performance of the supercapacitor cathode based on Co4Sb11.2Sn0.02Te0.78 is attributed to the more redox active sites and the improved electrical conductivity. Furthermore, this work provides a promising strategy for developing high-performance next-generation supercapacitor electrode materials.
A Simulation Model for the Analysis of Laser Cutting of Stainless Steel Sheets
Authors: Babalová Eva , Behúlová Mária
Published: December 2023

In laser cutting processes, the removal of material is achieved without the application of external force, distinguishing it from traditional machining methods. An additional advantage of laser cutting is the ability to achieve desired surface quality in a single step, eliminating the need for additional finishing processes to smoothen and clean the cutting surface. To ensure the quality of the resulting cuts, a comprehensive understanding of the thermal behavior of the cut parts, influenced by the movement of the laser beam, is essential. The article focuses on the numerical simulation of the laser cutting process of the AISI 304 steel sheets with a thickness of 2 mm to investigate the impact of laser cutting parameters on transient thermal fields and the quality of the resulting cuts. A simulation model was developed and verified through temperature measurements during an experimental laser cutting process using the Bystronic Bysprint 3015 CO2 Laser Cutting Machine. Numerical simulations in ANSYS software were used to design a working diagram showing the relationship between laser power and cutting kerf width for three different cutting speeds: 2000 mm.min-1, 4000 mm.min-1, and 5000 mm.min-1.

Published: December 2023

The utilization of egg-shell powder (ESP) as a bio-fillers for the extender calcium carbonate (CaCO3) in the biopolymer materials was examined in this research. Polylactic acid (PLA) and polybutylene succinate had selected as the biopolymers which were prepared via melt blending and mixed with 5 wt% of ESP for the fabrication of composites. The different ratios between PLA and PBS in the sample were blended in the intermeshing internal mixer at various contents. The properties of this study were characterized by mechanical properties, morphological properties, and thermal behavior. Ultimate tensile strength and modulus of the blends were reduced when filled with increasing PBS. On the other hand, there were no significant changes in the elongation at break and impact strength of PLA/PBS blending composites. SEM micrograph showed the outcome on the fracture surface sample which could be the poor interfacial adhesion of tertiary phases. DSC test revealed that PBS and ESP affected on the declination of melting temperature (Tm) and the percentage of crystallinity (%ꭓc) in PLA. Similarly, PLA and ESP could be decreased in the Tm and %ꭓc in PBS. Moreover, the minor phase of PBS (25 wt% of PBS), %ꭓc was the highest of the PBS phase of all samples.
Optimization for Current-Enhanced Solid-Phase Deposition of Multi-Layer Graphene with High Crystallinity and Uniformity
Authors: Tsuchida Ryutaro , Ueno Kazuyoshi
Published: December 2023

Solid-phase deposition (SPD) is a preferable method to fabricate multi-layer graphene (MLG) for device applications since MLG can be deposited directly on substrates without transfer. Previously, we reported that current application during SPD enhances the MLG growth. In this study, we investigated the effects of applied current and heating rate on the crystallinity and uniformity of MLG precipitated from carbon (C) / nickel (Ni) structures. It was found that higher current and slower heating rate lead to improve the MLG crystallinity. Moreover, the uniformity was improved by the optimization of Ni and C thickness which could control the nucleation and growth of MLG during SPD. As a result, a uniform MLG with a high G/D ratio of 5.5 was obtained at a low temperature of 365 °C.
CFD Analysis of Perforated Plates and Open-Cell Materials Aerodynamics
Authors: Miguel Antonio Ferreira
Published: December 2023

In this paper, a numerical study of fluid flow through perforated panels with square holes and open-cell material with cubic cells is presented. Structures with a wide variety of porosities (0.15<φ<0.94) and Reynolds numbers (0.01<Re<6000) are studied. Among the various outcomes obtained, the results indicate that pressure gradient vs Reynolds number exhibits three different forms of variation, including linear (Re<1), nonlinear (1≤Re<4000), and one where the pressure gradient is virtually constant with the Reynolds number (Re≥4000). The results were provided in terms of loss factor, but also of intrinsic permeability and the Forchheimer coefficient. Relationships that connect porosity to the loss factor, intrinsic permeability, and Forchheimer coefficient are also presented. These findings may prove useful in better understanding the flow behaviors in perforated panels and cell metal foams, which have a wide range of applications.

Lissencephaly is a rare genetic brain developmental disease characterized by brain malformations, eye anomalies, and congenital muscular dystrophy. The present case is of a 2-year-old child previously diagnosed with lissencephaly, which was well managed with Ayurvedic treatment protocol, in addition to conventional antiepileptic medicines. The patient presented with delayed milestones and recurrent episodes of seizures. Sarvangavata, Kapha Avrita Vyana Vata, and Vyadhija Phakka were the probable Ayurvedic diagnoses considered. Agnideepana (stimulation of digestive/metabolic factors), Srotoshodhana (bio-cleansing of structural and functional channels), Balya (promoting strength), and Vata Shamaka (pacification of Vata Dosha) were the treatment principles adopted in this case. Indukanta Ghrita, Rajanyadi Churna, Gopichandanadi Vati, and Sahacharadi Kashaya were administered internally. Procedures such as Abhyanga (oil massage), Dhanyamla Dhara (therapeutic streaming of sour rice gruel over the body), Pratimarsha Nasya (medication through nasal route), and Jihvalepa (tongue anointment) were performed externally. The child achieved some important milestones within 37 days of inpatient (IP) and 2 months of outpatient treatment; no single episode of seizure was reported during the period. This case report advocates the institution of Ayurvedic treatment protocol in improving the quality of life of lissencephaly patient as an add-on therapy.

This study aimed to examine the demographic characteristics, knowledge, and attitudes of health-care professionals and pregnant women regarding the association between maternal periodontitis and adverse obstetric outcomes.

Materials and Methods:

A cross-sectional study was conducted with 400 health-care professionals and 400 pregnant women. Demographic data, including gender, age group, education level, and occupation, were recorded. Mean knowledge and attitude scores were computed and compared between the two groups.

Results:

Health-care professionals demonstrated a good understanding of the association between maternal periodontitis and adverse obstetric outcomes, as evidenced by their higher mean knowledge score of 7.82 ± 1.75 out of 10. In contrast, pregnant women exhibited lower mean knowledge scores of 4.53 ± 1.34, indicating the presence of knowledge gaps within this group. Both health-care professionals and pregnant women expressed positive attitudes, with mean scores of 4.58 ± 0.89 and 3.92 ± 1.12, respectively. However, health-care professionals demonstrated a slightly more positive attitude than pregnant women.

Conclusions:

The study revealed a notable difference in knowledge levels between health-care professionals and pregnant women concerning maternal periodontitis and obstetric outcomes. While health-care professionals exhibited a higher understanding of the association, pregnant women showed some knowledge gaps. Nevertheless, both groups displayed positive attitudes toward the topic. The findings underscore the importance of targeted educational interventions to improve knowledge among pregnant women and enhance patient care by health-care professionals in relation to maternal periodontal health and its impact on obstetric outcomes.
The Importance of Body Posture in Adolescence and its Relationship with Overall Well-being
Authors: Sharma Sachi , Rawat Vikas
Published: December 2023

Adolescence is a phase of life with specific health and developmental needs. This is the time to develop self-image and self-esteem, learn to manage emotions and relationships, acquire attributes and abilities, and also physiologically form body posture. An efficient, erect posture of the human body is defined as the alignment of particular body segments that are not affected by pathological changes. Body posture is influenced by a variety of physiological, occupational, and biomechanical factors. It is very important to know these factors and their influence on posture to prevent the appearance of postural deviations and its consequence in their daily lives. This study is a review of articles related to the formation, defects, and corrective measures of body posture during adolescence and identifying its relationship with different aspects of health. This study identified 207 studies on the various aspects of posture in children and adolescents using search engines such as Google Scholar, Science Direct, and PubMed, of which 11 studies met the eligibility criteria for the review. Postural defects are no longer confined to medicine and affect society as a whole. It plays a significant role in defining the social personality of an individual and is responsible for his upbringing. Since these disorders are prevalent in children, it is necessary to emphasize the importance of prevention programs. Thus, children should be taught the habit of maintaining proper posture along with increasing their physical activity levels and promoting healthy lifestyles.

Published: December 2023

BACKGROUND:

Rheumatoid arthritis (RA) is a chronic, degenerative disease of the connective tissue, mainly involving the synovial joints, characterized by swelling, pain, and tenderness in multiple joints, associated with morning stiffness, fever, and weakness. RA treatment aims to reduce patients’ clinical symptoms, reduce or prevent joint damage, prevent progression, and improve quality of life. Due to complex RA pathogenesis, multiple interventions are usually required to control the symptoms. Ayurveda offers a wide range of therapeutic interventions that have a potential role in RA. The present study was planned to explore the role of Ayurveda interventions, Vyoshadi Guggulu (VG) and Panchasama Churna (PC), in managing RA.

MATERIALS AND METHODS:

An open-label, single-arm, prospective clinical study was conducted at Central Ayurveda Research Institute, Bhubaneswar, on 90 trial participants between the ages of 20 and 60 years having the clinical symptoms of RA according to the American College of Rheumatology. The trial drugs, viz., VG 1.5 g (3 tablets of 500 mg each) and PC 3 g, twice daily (in the morning and night after food) with lukewarm water, were administered for 84 days. Paired sample t test was used to compare the mean change in the subjective and objective parameters from baseline day to 84th day. The primary outcome measure was Disease Activity Score-28 (DAS-28), and the secondary outcome measures were Disability Index Score (The Indian Health Assessment Questionnaire), change in acute phase reactants—erythrocyte sedimentation rate (ESR), C-reactive protein, and change in Health Questionnaire short form (SF)-36 score.

RESULTS AND DISCUSSION:

Data from a total of 89 participants were subjected to statistical analysis, and significant change (P value < 0.001) was observed in the DAS-28 score, Disability Index Score, ESR scoring, and in all the domains of SF-36 Health Survey from baseline day to 84th day. The laboratory assessment parameters, such as liver function test, renal function test, and complete blood count, were within the reference range during the entire study duration, indicating that the interventions VG and PC were safe for the given dose and duration of consumption.

CONCLUSION:

Based on relief observed in the Ayurveda and modern clinical parameters, DAS-28 score, ESR, and Disability Index Score, it is concluded that VG and PC are effective in the management of RA and were found safe in the given dose and duration of consumption.

Published: December 2023

Purpose:

The purpose of this study is to evaluate the effect of corneal collagen cross-linking on visual acuity and corneal parameters like keratometry and pachymetry.

Methods:

It was a retrospective, noncomparative, open-label study conducted at a tertiary eye care center. The eyes that underwent epithelium-off CXL (corneal collagen cross-linking) for progressive keratoconus between 2018 January and 2019 December, and who completed 24 months' post-CXL follow-up, were included in the study. Data regarding uncorrected and best spectacle-corrected visual acuity (UCVA and BSCVA) and corneal topography parameters, that is, K
max, K
min, and pachymetry at thinnest point, were collected prior to the procedure and 2 years after the procedure.

Results:

A total of 92 eyes of 65 patients were included in the study. There was a significant improvement of logMAR BCVA from preoperative 0.40 ± 0.24 to 0.28 ± 0.19 at 24 months after CXL (P < 0.001). UCVA also increased from preoperative value of logMAR 0.70 ± 0.28 to 0.61 ± 0.26 2 years postoperatively (P < 0.001). The number of eyes achieving BCVA of 0.3 logMAR or better significantly increased from 54 (58.7%) preoperatively to 72 (78.26%) at 2 years and it was found to be statistically significant (P < 0.001).

Published: December 2023

Purpose:

Retinal artery occlusion (RAO) is an ophthalmologic emergency and involvement of both eyes is rare. The aim of this study was to determine the pattern of presentation of bilateral RAO in south India and the associated systemic disorders.

Methods:

A retrospective review of the medical records of patients with bilateral RAO seen at a tertiary eye hospital in south India over a period of eight years was carried out. The patient's demographic and clinical data were extracted from the case files and analyzed using Epi Info statistical software.

Results:

Six hundred and seventy-four eyes of 662 patients were seen with RAO during the period of the study with 12 (1.8%) patients having bilateral involvement. The mean age of the patients was 58.3 years and males comprised 66.7%. There were 22 (91.7%) eyes with CRAO, and two (8.4%) with branch RAO. Three (25%) patients had simultaneous RAO. The median interval for the involvement of the fellow eye was 90 days. Hypertension and diabetes were the most commonly associated systemic disorders.

Conclusion:

Bilateral RAO is very rare and usually nonsimultaneous. Patients need to be aware of the possibility of involvement of the fellow eye after a unilateral RAO, and the importance of seeking medical care promptly if this occurs.

Periodic maintenance of stack aviation lamps was taken up in the Compact Reprocessing of Advanced Fuels in Lead Cells reprocessing plant in Kalpakkam. The entire ventilation system of the plant had to be shut down during this maintenance work. When the ventilation system is switched off, natural radioactivity will build up in the working environment. The increased magnitude of the natural radioactivity concentration was estimated by counting the air samples (AS) at predetermined intervals to ensure no long-lived radionuclide (LLR) was present in the AS. The extent of the natural radioactivity rose to a factor of 100, and no LLR was present in the collected AS. In addition, the collected AS and data analysis of the same revealed that there was no breach of containment during the work.
Preprosto, ne trezno – slovenska prevoda Flaubertove Salambô
Authors: Marinčič Katarina
Published: December 2023

Članek obravnava dva slovenska prevoda Flaubertovega kontroverznega zgodovinskega romana Salambô, ki je v izvirniku izšel leta 1862, pet let po izidu realistične mojstrovine Gospa Bovary.
Prvi slovenski prevod iz leta 1931 je delo Antona Debeljaka, prevajalca in publicista, ki je bil v svojem času zagotovo vodilni slovenski poznavalec Flauberta in nasploh francoske književnosti. Kot kritik oziroma literarni zgodovinar je bil Debeljak prepričan, da je Flaubert v Salambô (kljub temu, da gre za delo z zgodovinsko, eksotično tematiko) ostal zvest principom realističnega romana. To trditev je argumentiral zlasti z analizo Flaubertove pripovedne tehnike, za katero je značilna odsotnost pripovedovalca, njen temeljni princip pa je slikanje (ne pojasnjevanje in komentiranje) resničnosti. Debeljakov prevod je v tem pogledu zelo zvest izvirniku: prevajalec je skrbno ohranil zakonitost nizanja prizorov, pa tudi značilni ritem izvirnika. Manj posrečen je izbor besedišča. Debeljaka, ki je, kot lahko zaznamo tudi v njegovih lastnih besedilih, čutil posebno nagnjenje do manj znanih besed in arhaizmov, je to nagnjenje ponekod odvedlo zelo daleč od Flaubertovega izvirnika.
Drugi slovenski prevod Salambô (z letnico izida 2023) je delo prevajalke Saše Jerele.
Prevod Flaubertovega zgodovinskega romana lahko štejemo za logično nadaljevanje njene prevajalske poti, ki se je začela s Hadrijanovimi spomini Marguerite Yourcenar, pomemben mejnik na njej pa je bilo gotovo tudi Jezusovo življenje Flaubertovega sodobnika Ernesta Renana. V obeh primerih se je prevajalka mojstrsko prilagodila slogu izvirnika in tako – kljub navidezni podobnosti med “učenima” zgodovinskima romanoma – v celoti ohranila razlike med njima. V novem prevodu Salambô je Saša Jerele z velikim posluhom in skrbno pretehtanimi sredstvi, brez nasilnega prilagajanja slovenske skladnje francoski, poustvarila ritem izvirnika. Izvirniku pa je ostala zvesta tudi v izboru besedišča. Z veliko obvladanostjo, z doslednim izogibanjem cenenim učinkom, ji je uspelo v slovenščini poustvariti roman, kot si ga je zamislil Flaubert: preprost, ne trezen.
Metaphorical Conceptualization of Positive and Negative Emotions in Italian
Authors: Stanič Daša
Published: December 2023

The aim of this article is to discuss the conceptualization of negative and positive emotions in Italian. In other languages, emotions have been found to have a very complex conceptual structure. Many authors (Fainsilber and Ortony 1987; Fussell and Moss 1998; Gibbs 1994; Kövecses 2000a; Gibbs, Leggitt and Turner 2002; Kövecses 2014) who worked on the conceptualization of emotions make it clear that metaphorical language plays an important role in understanding the language of emotions, not only describing and categorizing emotional experiences, but also defining them more precisely and even creating them. Since valence is one of the most important features of emotions, we were interested in how it influences their conceptualization and how differences in valence are manifested at the level of metaphors and metaphorical linguistic expressions. We analysed more than 150,000 concordances from the itWaC corpus and found that emotions in Italian have a complex conceptual structure. Comparing the results by valence, we found that the differences between emotions with positive and negative valence do not occur at the level of basic metaphors, but at the level of some specific metaphors and even more clearly at the level of metaphorical linguistic expressions. We found that while all emotions are perceived as OPPONENT / ENEMY, this source domain applies in particular to emotions with negative valence. Only emotions with negative valence are perceived as OPPONENT WE FIGHT, which means that we have to overcome and control them. In contrast, only positive emotions are perceived as LIGHT, MEDICINE, DRUG and BUILDING. As with the metaphor EMOTIONS ARE FOOD, positive valence is clearly associated with a good and sweet taste and negative valence with a bitter taste. If emotions with a positive valence are perceived as LIGHT, emotions with a negative valence are perceived as DARKNESS (SADNESS), COLD (FEAR) and HEAT (ANGER). At the level of metaphorical linguistic expressions, we found some other interesting differences.

The learning environment that promotes fairness, justices, safety, and general wellbeing of the child can be termed a child friendly and productive school. Administrators recognize that alcohol abuse and addiction amongst school teachers are threats to fundamental peace, effective leadership, and friendly and productive organizational school climate. This poses a barrier to educational goal achievement. To achieve the goal of obtaining conducive and organizational friendly climate, the teachers need to be drug free and in an emotional stable state to plan, organize, direct and carry out teaching and learning in a friendly and productive school climate in an effort to achieve desired individual and group objectives with optimum efficiency and effectiveness. This study is a descriptive survey. Four research questions and three hypotheses guided the study. The participants were purposefully selected from teachers in Agbor metropolis, Delta, Nigeria. The sample consists of 73 teachers. A structured questionnaire designed in a five-point Likert scale format was analyzed using the mean, standard deviation and Chi Square to analyze the generated research questions and hypotheses. The results show that there is significant difference between male and female teachers’ alcohol consumption, and teachers’ alcohol abuse affect very negatively school climate and learning environment. Alcohol consumption by teachers can induce disorganization, ill health and promote levity which might inhibit a friendly and productive school climate.
Perspectives in Nutrition Therapy Education

Published: December 2023

The teaching and learning of nutrition science as well as its application to clinical practice are all included in the dynamic and ever-evolving discipline of nutrition therapy education (NTE). A range of viewpoints are necessary for NTE educators to properly instruct and engage students. This review article examines the perspectives in NTE and suggests crucial viewpoints that are necessary for efficient instruction. The scientific basis of nutrition is essential for NTE educators. This includes knowledge of biochemistry, physiology, and the scientific method. NTE educators should have a strong understanding of clinical nutrition practice. This includes knowledge of assessment techniques, nutrition interventions, and the management of various medical conditions. NTE educators should be aware of the cultural diversity of their students and how culture influences food choices and nutrition beliefs. NTE educators should understand the nutritional needs of individuals across the lifespan, from infancy to old age. NTE educators should recognize that nutrition is one aspect of a person's overall health and well-being. They should consider the interconnectedness of nutrition, physical activity, mental health, and social factors. NTSE educators should encourage students to think critically about nutrition information and to evaluate the credibility of sources. These six viewpoints can be incorporated into NTE to assist educators in giving their students a more thorough and interesting learning experience. Through an awareness of the various perspectives that impact nutrition, NTE instructors may better equip their students to become well-rounded and productive nutritionists.

The study assessed socio-economic and environmental factors influencing student nurses’ preparedness for the Qualifying Examination for General Nurses (QEFGN) in school of nursing in Agbor, Delta State, Nigeria. A descriptive survey research of 70 third-year student nurses of Basic Nursing program were selected using convenience sampling technique. Data collected using researchers-developed questionnaire were summarized with simple frequencies, percentages, mean and standard deviation. Average mean scores of 4.17 and 1.98 indicated environmental factors influenced student nurses’ preparedness for QEFGN while socio-economic factors did not. There was no significant association between gender and socio-economic cum environmental factors influencing preparedness for QEFGN. While environmental factors influenced preparedness for QEFGN, socio-economic did not. It was recommended that administrators of nursing training institutions should ensure that adequate and lasting lighting is supplied with a solitary environment provided for the students preparing for the exam.

Com o avanço tecnológico, compreende-se que muitas mudanças ocorreram no mundo moderno, ajudando as pessoas a cumprirem as suas atividades de forma diferenciada daquela aproveitada no passado. Tal período de mutação contribuiu claramente para que a sociedade permanecesse mais atenta ao aproveitamento das práticas tecnológicas, usando-as inclusive no meio educacional, mantendo, assim, um maior tempo de constância na rede. Por outro prisma, percebeu-se que o surgimento tecnológico contribuiu ainda para que os relacionamentos dentre indivíduos sofresse uma alteração brusca, deixando em segundo plano as tão antigas conversas presenciais, dando ênfase ao contato virtual. Um claro exemplo de uma aplicação bem-sucedida da IA, especialmente quando se fala da Educação, foi o uso da Ferramenta Google na escola. Com isso, percebeu-se que o avanço tecnológico, com destaque para a Inteligência Artificial, tem demudado de forma expressiva a vida do indivíduo na sociedade, agenciando uma relação diferenciada, seja no ambiente social, no educacional (foco deste estudo), ou ainda no profissional. Com este panorama em mente, entende-se ser pertinente salientar que o avanço tecnológico, através do aproveitamento da Inteligência Artificial, tem um lugar importante no campo educacional, trazendo consigo múltiplos benefícios que se mostram capazes de influenciar expressivamente o método de ensino- aprendizagem, sendo claramente uma ferramenta motivacional, para que estudante queira desenvolver seus potenciais, contribuindo assim para que os educadores tenham em mãos um novo padrão de ensino, indispensável à sua prática cotidiana. Para discutir tal assunto, foi feita uma pesquisa de cunho bibliográfico, que contribuiu com material teórico, pertinente ao tema aqui abordado.
Tighter Trail Bounds for Xoodoo
Authors: Mella Silvia , Daemen Joan , Van Assche Gilles
Published: December 2023

Determining bounds on the differential probability of differential trails and the squared correlation contribution of linear trails forms an important part of the security evaluation of a permutation. For Xoodoo, such bounds were proven using the trail core tree search technique, with a dedicated tool (XooTools) that scans the space of all r-round trails with weight below a given threshold Tr. The search space grows exponentially with the value of Tr and XooTools appeared to have reached its limit, requiring huge amounts of CPU time to push the bounds a little further. The bottleneck was the phase called trail extension where short trails are extended to more rounds, especially in the backward direction. In this work, we present a number of techniques that allowed us to make extension much more efficient and as such to increase the bounds significantly. Notably, we prove that the minimum weight of any 4-round trail is 80, the minimum weight of any 6-round trail is at least 132 and the minimum weight of any 12-round trail is at least 264, both for differential and linear trails. As a byproduct we found families of trails that have predictable weight once extended to more rounds and use them to compute upper bounds for the minimum weight of trails for arbitrary numbers of rounds.
Propagation of Subspaces in Primitives with Monomial Sboxes: Applications to Rescue and Variants of the AES
Authors: Boeuf Aurélien , Canteaut Anne , Perrin Léo
Published: December 2023

Motivated by progress in the field of zero-knowledge proofs, so-called Arithmetization-Oriented (AO) symmetric primitives have started to appear in the literature, such as MiMC, Poseidon or Rescue. Due to the design constraints implied by this setting, these algorithms are defined using simple operations over large (possibly prime) fields. In particular, many rely on simple low-degree monomials for their non-linear layers, essentially using x ↦ x3 as an S-box.In this paper, we show that the structure of the material injected in each round (be it subkeys in a block cipher or round constants in a public permutation) could allow a specific pattern, whereby a well-defined affine space is mapped to another by the round function, and then to another, etc. Such chains of one-dimensional subspaces always exist over 2 rounds, and they can be extended to an arbitrary number of rounds, for any linear layer, provided that the round-constants are well chosen.As a consequence, for several ciphers like Rescue, or a variant of AES with a monomial Sbox, there exist some round-key sequences for which the cipher has an abnormally high differential uniformity, exceeding the size of the Sbox alphabet.Well-known security arguments, in particular based on the wide-trail strategy, have been reused in the AO setting by many designers. Unfortunately, our results show that such a traditional study may not be sufficient to guarantee security. To illustrate this, we present two new primitives (the tweakable block cipher Snare and the permutation-based hash function Stir) that are built using state-of-the-art security arguments, but which are actually deeply flawed. Indeed, the key schedule of Snare ensures the presence of a subspace chain that significantly simplifies an algebraic attack against it, and the round constants of Stir force the presence of a subspace chain aligned with the rate and capacity of the permutation. This in turns implies the existence of many easy-to-find solutions to the so-called CICO problem.
Cryptanalysis of HALFLOOP Block Ciphers

Published: December 2023

HALFLOOP is a family of tweakable block ciphers that are used for encrypting automatic link establishment (ALE) messages in high frequency radio, a technology commonly used by the military, other government agencies and industries which require high robustness in long-distance communications. Recently, it was shown in [DDLS22] that the smallest version of the cipher, HALFLOOP-24, can be attacked within a practical time and memory complexity. However, in the real-word ALE setting, it turns out that this attack require to wait more than 500 years to collect the necessary amount of plaintext-tweak-ciphertext pairs fulfilling the conditions of the attack.In this paper, we present real-world practical attacks against HALFLOOP-24 which are based on a probability-one differential distinguisher. In our attacks, we significantly reduce the data complexity to three differential pairs in the chosen-plaintext (CPA) setting which is optimal in the sense that even a brute force attack needs at least six plaintext-tweak-ciphertext pairs to uniquely identify the correct key. Considering the same ALE setting as [DDLS22], this translates to a reduction from 541 years to 2 hours worth of intercepted traffic.Besides, we provide the first, non generic, public cryptanalysis of HALFLOOP-48 and HALFLOOP-96. More precisely, we present Demirci-Selçuk meet-in-the-middle attacks against full-round HALFLOOP-48 and round-reduced HALFLOOP-96 to recover the complete master key in a CPA setting. However, unlike the attacks on HALFLOOP-24, our attacks on the larger versions are only theoretical. Moreover for HALFLOOP-96 the known generic time-memory trade-off attack, based on a flawed tweak handling, remains the strongest attack vector.In conclusion, we iterate what was already stated in [DDLS22]: HALFLOOP does not provide adequate protection and should not be used.
