The internet of things is a key driver for new developments in the fields of medicine, industry 4.0 and gaming. Consequently, the interaction of virtual and real world by smart interconnecting of devices in our everyday life is the basis idea of the Cluster of Excellence "Centre for Tactile Internet with Human-in-the-Loop" (CeTI) at TU Dresden. To enable a user-centric approach in CeTI innovative textile structures, mainly knitted smart gloves, and their functionalization by integration of sensors and sensory yarns are focus of research activities.
A Node-Based Strain Smoothing Technique for Free Vibration Analysis of Textile-Like Sheet Materials
Authors: Quyen Nguyen T. , Quoc Nguyen Trong , Tru Nguyen Dinh , Gomes Abel J.P. , Ferreira Fernando B.N.
Published: June 2022

This paper presents an implementation of the node-based smoothed finite element method and Reissner-Mindlin plate theory for a four node isoparametric shell element to improve the numerical precision and computational efficiency subjected to free vibration analysis of textile-like sheet materials. A one smoothing cell integration scheme in the strain smoothing technique is implemented to contrast the shear locking phenomenon that may exists in the analysis for moderately-thick and thick shell models. Various numerical results of free vibration analysis for a multi-layer nonwoven fabric sample are compared with other existing analytical solutions and numerical solutions in literatures to demonstrate the effectiveness of the present method. An advantage of the present formulation is that it can improve the numerical precision without decreasing the computational efficiency.

Published: June 2022

The Cluster of Excellence “Centre for Tactile Internet with Human-in-the-Loop (CeTI)” deals with developments and inventions concerning smart devices used in many fields, e.g. industry 4.0, medicine and skill learning. These kind of applications require smart devices, sensors, actors and conductive structures. Textile structures address these applications by meeting requirements such of being flexible, adaptable and wearable. Within this paper, the development of a protective coating for electrically conductive (EC) yarns is captured. These EC yarns are nowadays often used for smart textile applications. One challenge in their application is the integration into textile structures. Often, the handling and use of EC yarns lead on the one hand to damages on the surface of the yarn and on the other hand to reduced electromechanically characteristics. This paper aims to characterize these EC yarns in regard to develop a suitable protective coating based on polypropylene (PP). To achieve this development, an extensive characterization of the EC yarns as well as the protective coating itself is important. The surface free energy (SFE), the topographical and the chemical characteristics are necessary for developing a suitable protective coating. However, the yarns are characterized before and after implementation into the textile structure and furthermore after the coating respectively with the developed finish.

Published: June 2022

UV bonding technology’s biggest limitation is the need of a transparent joining part to be able to cure the adhesive with an external light source. This is to be solved with ribbon fabrics made with polymer optical fibres (POF) which guide the UV light into the adhesive bond. On the basis of previously published experiments, a set of POF fabrics with different thread densities and weft materials is evaluated optically regarding the emitted UV light intensity and mechanically regarding the shear strength of the adhesive bonds. A factorial experiment plan indicates that higher tensile lap-shear strength comes with lower weft fineness and higher weft density. The maximum shear strength achieved was 8.3 MPa with potential room for improvement due to non-cohesive failure, relatively high weft densities and a comparatively low powered UV light source.
Development of a Testing Protocol to Assess the Washability of E-Textiles
Authors: Rotzler Sigrid , Schneider-Ramelow Martin
Published: June 2022

Most e-textiles are developed for wearable use and thus need to be washable to guarantee a textile typical usability. Yet, there are no e-textile specific wash testing standards and as a result, employed testing protocols vary greatly, resulting in a lack of comparability. To address this issue, an e-textile wash testing protocol modelled after testing methods provided by the standard ISO 6330 (the standard currently most often used as a basis for e-textile wash testing) as well as gentle household washing methods was developed and verified regarding its cleaning capability.

Published: June 2022

The combination of sensor technology and textiles substantially extends the range of textile applications. Smart textiles, especially clothing, might increasingly be equipped with pressure sensors. They could be used in the sports or health sector to measure body activities or other activities which are close to the body. Therefore, it is essential to develop flexible sensors which allow to adapt to the properties of textile materials which are in contact with the body or surrounding it. In this paper a pressure sensor based on piezoresistive ink and conductive fabric with high flexibility is reported. Preliminary pressure sensors have been fabricated and tested on a universal testing machine. The sensors show to be functional, but also showing some aspects to improve, such as its hysteretic behaviour.

Published: June 2022

Electric and electronic devices are mainly emitting electromagnetic radiation, and shielding from radiation is essential. Electrically conductive materials are suitable for radiation shielding applications. The designing of the textile material for the radiation shielding is challenging because of its open area and design. In general, more open area has transmit the radiations tend to lesser in shielding. Another factor is the laying angle of the textile material also plays important role beyond open area. In this study, the effect of laying angle and open area was analysed for effective utilization of conductive materials. The conductive nonwoven fabric was used to form as strips to simulate the various textile structures for shielding application. The Cu/Ni coated ultrathin polyester nonwoven fabric sample is taken to form two-layers strips and test for electromagnetic shielding effectiveness. In experimental design, three factors of strips which are strips laid angle, strip thickness, and gap between the strips are taken at three levels. The strip cover area and aperture area were calculated geomentrically for each design and significant difference on shielding effectiveness was noticed.

With the rise of electromagnetic radiation-based technologies, considerable attention has been drawn to developing and implementing innovative electromagnetic shielding materials. Carbon nanomaterials and conductive polymers have been appealing to both academia and industry as promising alternatives for the traditionally used metallic materials, owing to their lightness, flexibility, easy processability and resistance to corrosion, which are of special importance for textile applications. In this work, multiwalled carbon nanotubes (MWCNTs) and poly (3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) have been applied to cotton textile substrates by straightforward scalable dyeing and coating processes, respectively. These processes led to uniform and homogeneous coatings with distinct properties: the fabric coated with MWCNT presented higher thickness and lower loading of incorporated material than the textile coated with PEDOT:PSS (thickness: 995 μm vs. 208 μm; material loading: 9.4 wt.% vs. 70.7 wt.%). The electromagnetic shielding properties were outlined for each shielding textile in the frequency range of 5.85–18 GHz: an average shielding effectiveness of ~35.6 dB was obtained for MWCNT@tex, while PEDOT:PSS@tex reached ~38.3 dB. Thus, PEDOT:PSS provided enhanced radiation shielding with lower coating thickness, while the MWCNTs led to improved attenuation with less material usage. Shielding effectiveness values above 30 dB were obtained for both electromagnetic interference shielding textiles, which corresponds to an excellent classification for general use applications, such as casual clothing and maternity wear.

Authors: Garg Shubham , Masheshwari Dilip , Bhushan Bharat , Sardana Vijay , Jain Raj Kumar
Published: June 2022

Background:

Mucormycosis (MCR) has been increasingly described in patients with coronavirus disease 2019 (COVID-19), but the epidemiological factors, neurological presentation, and outcome of such patients are not well described.

Aims:

To study the patient demographics, presenting symptoms and signs, the role of co-morbidities, medications used to treat COVID-19, and the outcomes of management and to study the spectrum of neuraxis involvement and its outcome.

Methods:

It was a prospective, observational, cross-sectional hospital-based single center cohort study. Confirmed MCR cases with and without COVID-19 were collected. The study was carried out over a period of 3 months from May to July 2021, followed by 3-month follow-up. Information on epidemiological factors, neurological findings, treatment (including medical and surgical treatment), and outcome was recorded.

Results:

A total of 141 patients were diagnosed with MCR, out of which 98 were COVID-associated MCR (CAM). The CAM incidence was 0.39% among COVID-19-positive patients. The MCR case fatality rate at 90 days was 43.9% but was higher for CAM than for non-CAM patients. Older ages (>50 years), diabetes mellitus, multiple risk factors, diabetic ketoacidosis on admission, brain involvement, and history of COVID-19 pneumonitis were associated with a higher risk for death.

Conclusions:

Possibly because of improper usage of corticosteroids, zinc, oxygen, and tocilizumab, there was sudden surge of cases of MCR in the COVID-19 pandemic. Therefore, treating physicians should use the COVID-19 pneumonia regimen judiciously. Neurological involvement itself is a poor prognostic sign, but combined surgical and medical management exhibited better outcome.

Published: June 2022

Large vessel occlusion stroke contributes to disability and mortality out of proportion to its incidence. Over time it was noted that intravenous thrombolysis alone was not sufficient for this stroke type. Slowly, endovascular approach and mechanical clot retrieval have come out to be the biggest advances in the field of neurology as well as modern medicine. Although the careful selection of patients is needed as standardized by landmark trials. At the same time, thrombectomy is now being studied in patients excluded by previous trials and is seemingly coming out be effective in the vast majority of patients with large vessel occlusions. Further, techniques and devices are getting refined day by day to achieve the maximum possible benefit.

Authors: Agarwal Ayush , Pankaj  , Faruq Mohd. , Garg Ajay , Srivastava Achal K.
Published: June 2022

Spinocerebellar ataxias (SCAs) comprise a group of complex and heterogeneous hereditary neurodegenerative disorders characterized by cerebellar ataxia, with ophthalmoplegia, pyramidal and extrapyramidal features, peripheral neuropathy, motor neuron disease, pigmentary retinopathy, epilepsy, and dementia in varying proportions. Cognitive impairment is not frequent in SCAs but is rarely noticed since it gets camouflaged behind the exorbitant ataxic manifestations of the disease. The exact incidence and extent of cognitive impairment in these rare disorders are not known due to the heterogeneity between different SCA types and different modalities of testing employed in different studies. Through our review, we have summarized the cognitive aspects of SCA and can safely conclude that cognitive dysfunction is common in some SCA types when compared to others. Not only is it important to appreciate its presence as a symptom complex in SCA but also is the need to actively search and treat it to improve the patients' quality of life.

Authors: Soumiya Ravi , Paul Birinder S. , Aggarwal Riya , Paul Gunchan
Published: June 2022

Methods:

This was a hospital based observational cross-sectional study of PD patients attending the Neurology OPD of a tertiary care hospital. The prevalence and type of neuropathy was determined using the validated MNSI scale. The nutritional status was assessed using MNA score and PDQ-39 was used for assessing quality of life. Patients with and without neuropathy were compared to ascertain risk factors for neuropathy.

Results:

Twenty-four out of 93 PD patients (26%) had neuropathy and 12 (50%) out of them had painful neuropathy. Older patents and those who had longer duration of disease had higher prevalence of neuropathy. In addition there was significant correlation with malnutrition and neuropathy. 79% of patients with neuropathy had abnormal nutritional status. On comparison of patients with painful neuropathy as compared to those without pain, Vitamin B 12 levels were found to be low only in the former group.

Conclusions:

Our study shows that there is significant prevalence of neuropathy in PD patents that affects the quality of life of PD patients. Neuropathy in PD is disease dependent and is precipitated by malnutrition. Hence, neuropathy must be timely diagnosed and effective nutritional management may help to improve the patient's quality of life.
The optimal concentration of intralesional triamcinolone acetonide for patchy alopecia areata
Authors: Su Hsuan-An , Chen Yu-Tsung , Chen Yu-Chia
Published: June 2022

Background:

Intralesional steroid treatment for alopecia areata (AA) has been developed for decades, yet the optimal concentration of triamcinolone acetonide (TrA) is not well-established.

Objectives:

This review aims to determine the optimal concentration of intralesional TrA in treating patchy AA.

Methods:

We conducted a systematic review and meta-analysis, and searched the Cochrane Library, Embase, and PubMed databases on July 4, 2021, to identify randomized or nonrandomized comparative studies reporting the response rates and/or adverse events among AA patients treated with various concentrations of TrA. The meta-analysis of proportions and odds ratios was analyzed using random-effects modeling.

Results:

Nineteen studies and a total of 783 participants were included. The estimated response rate of 5 mg/dl (74.82%, 95% confidence interval [CI] 64.99%–83.50%) was shown to be more efficacious than 2.5/3.33 mg/dl (38.64%, 95% CI 16.98%–62.99%) but similar to 10 mg/dl (71.06%, 95% CI 59.72%–81.20%), while pooled estimate of odds ratios revealed higher efficacy with 10 mg/dl than 5 mg/dl (odds ratio = 1.64, 95% CI 1.05–2.58, P = 0.031). The rates of skin atrophy were 18.05% (95% CI, 10.32%–27.38%), 11.49% (95% CI, 2.86%–24.84%), and 3.85% (95% CI, 1.27%–14.01%) in groups 10, 5, and 2.5/3.33 mg/dl, respectively. Higher concentration is associated with more skin atrophy in a dose-dependent fashion (P = 0.012). Heterogeneity among studies in the meta-analyses was high.

Conclusion:

The optimal intralesional concentration of TrA for patchy AA is probably 10 mg/dl with acceptable adverse events.

Authors: Yen Chia-Hsien , Lee Chih-Hung , Ho Ji-Chen
Published: June 2022

Background:

Extramammary Paget's disease (EMPD) is a rare malignancy occurring on apocrine sweat gland-bearing skin with occasional association with internal cancers. Its epidemiological characteristics are different between populations in Asian and Western countries.

Objectives:

The aim of this study was to report the clinical experience of EMPD in a single medical center in Taiwan, compare our results with previous literature, and provide strategies for diagnostic workup.

Methods:

Medical records and biopsies of 34 Taiwanese patients with EMPD, treated in a single medical center in Kaohsiung, Taiwan, from January 2000 to December 2019, were reviewed. The clinicopathological features, biological behavior, management, and follow-up courses of these patients were analyzed.

Results:

We found a male predominance in our 34 patients with EMPD, and most patients were diagnosed in their 70s. Only four patients (11.8%) had an associated malignancy while the rest had a primary cutaneous lesion. Most patients (22, 64.7%) underwent wide excision (22, 64.7%), with the rest adopting other various therapeutic modalities. The 5-year overall survival rate was 76.5%, and the statistically significant prognostic factors for survival were lymph node involvement (P < 0.001) and dermal invasion (P = 0.022).

Conclusion:

In summary, this single-center study described the clinical and histopathologic features of patients with EMPD in Taiwan with a review of literature. We also proposed a complete systemic workup when the diagnosis was made and an extended follow-up period as long as 5 years after the initial treatment.
Pentoxifylline in the treatment of generalized granuloma annulare
Authors: Kharkar Vidya D. , Rajendran Harish Balaji , Bhargava Anmol
Published: June 2022

Granuloma annulare (GA) is a benign self-limited granulomatous cutaneous disorder of unknown etiology. Clinical variants include localized, generalized, perforating, and subcutaneous. Generalized or disseminated GA is an uncommon variant displaying some clinical features that differentiate it from the localized form, including later age of onset, inadequate response to treatment, and less tendency to spontaneous resolution. The treatment modalities used for localized GA (topical or intralesional steroids, freezing with liquid nitrogen, or surgical excision) cannot be successfully applied to the large numbers of lesions seen in GA’s generalized form. Systemic treatments have included dapsone, chlorambucil, isotretinoin, systemic steroids, cyclosporine, salicylates, chloroquine, and PUVA. These treatments have potentially serious side effects in the long term and have not demonstrated consistent results. Literature overuse of pentoxifylline in the treatment of GA is limited. Here we report three prospective cases of generalized GA showing resolution with oral pentoxifylline.
Topical 5-fluorouracil for Basal Cell Carcinoma
Authors: Bhokare Anil Balkrishna
Published: June 2022

Basal cell carcinoma is a malignant epithelial tumor arising only in skin, from the basal layer of the epidermis or of the pilosebaceous adnexa. Diagnosis often depends on skin examination, confirmed by tissue biopsy. Treatment is typically by surgical removal. This can be by simple excision if the cancer is small; otherwise Mohs surgery is generally recommended. Other options may include topical chemotherapy, laser therapy, or the use of imiquimod. In this study, we conclude topical 5-fluorouracil is a highly effective and well-tolerated treatment option for superficial basal cell carcinomas.

Authors: Mahajan Harshal , Jain Gaurav K. , Dhoot Dhiraj , Deshmukh Gaurav A. , Barkate Hanmant V.
Published: June 2022

Background and Objective:

Super bioavailable itraconazole is a newer formulation of itraconazole, which overcomes challenges encountered with the use of conventional itraconazole like interpatient variability, limited absorption, reduction in its absorption with co-administered gastric acid lowering agents, etc. The present study was done to evaluate the plasma pharmacokinetics, sebum concentrations of super bioavailable itraconazole in comparison with conventional itraconazole.

Materials and Methods:

Twelve healthy Asian Indian male healthy volunteers were enrolled in single-center, open-labeled, two treatments, multi-dose, parallel pharmacokinetic study. Test drug (T), i.e. super bioavailable itraconazole 50 mg, was given to six volunteers twice daily after meals for 7 continuous days. Reference drug (R), i.e. conventional itraconazole 100 mg, was given in similar way to the remaining six volunteers. Concentration of the itraconazole in plasma in both the groups was quantified by using high performance liquid chromatography. Concentration of the itraconazole in sebum was measured by paper absorption method.

Results:

The plasma concentration of itraconazole in both the groups was comparable at all-time points. The maximum concentration (Cmax) and area under curve in test group was higher as compared to reference group. The relative bioavailability of test drug was 107% as compared to the reference drug. The intersubject variability was less in test group (8.37%) as compared to reference drug (19.82%). At day 7, the mean sebum concentration of itraconazole in test drug group was 11.6% higher as compared to reference drug (P = 0.01).

Conclusion:

It is apparent from the study outcomes that super bioavailable itraconazole (50 mg) is bioequivalent to the conventional itraconazole (100 mg) along with less intersubject variability, and most importantly higher sebum concentration as compared to conventional itraconazole.
A case series of generalized Lichenoid Drug Eruption due to Anti-Tubercular Drugs
Authors: Pathave Hari , Dongre Atul , Gund Gayatri , Goutham Sapna , Nayak Chitra
Published: June 2022

The spectrum of tuberculosis-associated cutaneous adverse drug reactions (ADRs) is wide and includes Stevens-Johnson syndrome, drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome and generalized lichenoid drug eruption (LDE). LDE constitutes less than 10% of the total incidence of anti-tubercular drug induced cutaneous ADRs. In any type of drug reaction there is a prompt need of withdrawal of suspected drugs and institution of aggressive treatment of ADRs with proper control of underlying primary disease. Herein, we present a case series of five cases of generalized LDE due to anti tubercular therapy (ATT), in whom cutaneous lesions were managed with oral immunosuppressants while continuing ATT.

Published: June 2022

Introduction:

Crizotinib is a tyrosine kinase inhibitor used in patients with non-small cell lung cancer, and there are uncertainties about its effect on kidney function. In this study, it was aimed to document the possible adverse effect of the drug on kidney functions.

Materials and Methods:

The estimated glomerular filtration rates (eGFRs) of the patients were calculated by creatinine-based Chronic Kidney Disease Epidemiology Collaboration and compared by months using the paired samples t-test. Kaplan–Meier survival method was used for progression-free survival and overall survival (OS) analysis.

Results:

Twenty-six patients who received crizotinib were included in the study, and the median progression-free survival time with crizotinib was 14.2 months and the median OS time was 27.4 months. There was a significant reduction of eGFR after the 1st month of crizotinib treatment when compared to the rate before treatment initiation (P < 0.001). The eGFR values at the end of the 1st month and the 2nd month of treatment and the 2nd and 3rd months of treatment were statistically similar (P = 0.086, P = 0.663; respectively). This decrease in eGFR values was reversible, and there was no difference detected between pretreatment and posttreatment discontinuation (P = 0.100).

Conclusion:

A reversible decrease in renal functions was detected in patients using crizotinib. When the literature data are examined, it is thought that the reason for this decrease may be related to the increase in renal inflammation or a pseudo decrease due to the decrease in creatinine excretion. When evaluating renal functions in these patients, using noncreatine-based (iothalamate, etc.) calculations can give more accurate results.
Families of singular Kähler–Einstein metrics
Authors: Di Nezza Eleonora , Guedj Vincent , Guenancia Henri
Published: June 2022

Refining Yau’s and Kołodziej’s techniques, we establish very precise uniform a priori estimates for degenerate complex Monge–Ampère equations on compact Kähler manifolds, that allow us to control the blow up of the solutions as the cohomology class and the complex structure both vary.

We apply these estimates to the study of various families of possibly singular Kähler varieties endowed with twisted Kähler–Einstein metrics, by analyzing the behavior of canonical densities, establishing uniform integrability properties, and developing the first steps of a pluripotential theory in families. This provides interesting information on the moduli space of stable varieties, extending works by Berman–Guenancia and Song, as well as on the behavior of singular Ricci-flat metrics on (log) Calabi–Yau varieties, generalizing works by Rong–Ruan–Zhang, Gross–Tosatti–Zhang, Collins–Tosatti and Tosatti–Weinkove–Yang.

Integer solutions to bankruptcy problems: The IPROP solution
Authors: Fragnelli Vito , Gastaldi Fabio
Published: June 2022

A widely studied problem is that of a bankruptcy, where several agents claim different amounts of a resource, the
estate
, that is not enough to satisfy all claims. In some occurrences, the estate is made by integer unities: several contributors (among them also the authors) have proposed different approaches related to some of the classical apportionment rules. In this paper, we analyze the possibility of extending the proportional method to the integer situation which occurs, typically, when the seats in a Parliament are assigned according to a proportional electoral law: our aim is to provide an approach, different from the usual round, and give rests strategy (which may lead to paradoxes), enough intuitive and easily applicable.
Bark volume and thickness in teak trees with different spacings
Authors: Vendruscolo Diogo Guido Streck , Cunha Neto Felipe Vieira , Fraga Isabel Matos
Published: June 2022

The bark in some forest species may represent a significant volume of the trunk, demanding the use of efficient methods to estimate bark volume indirectly through equations. The aim of this study was to evaluate bark volume and thickness in teak (Tectona grandis) trees planted at different densities. Volume data were used to evaluate the percentage of bark in different portions of the trunk. Averages were compared by the Tukey test (p < 0.05%) and regression analysis (polynomial model) was used to predict bark thickness along the trunk. The effect of spacing on bark thickness was compared by the model identity test. The percentage of bark in more densely planted teak trees was higher. The percentage of bark decreases from the base to the top of the tree trunk, with an average volume of green bark reaching 24% to 30% of the total volume. Increasing spacing promotes higher absolute average bark thickness.
Economic Instruments in Environmental Policy in the Republic of Serbia
Authors: Gogić Nemanja
Published: June 2022

The starting point from which we started our research is the classification of the Republic of Serbia by European environmental organizations as one of the most polluted countries in Europe. With the opening of Chapter 27, in order to join Serbia to the European Union, devastating data on the current state of the environment were presented. In the last thirty years, the Republic of Serbia has invested little or nothing in environmental protection. The aim of the research is to point out the importance and role of the introduction of economic instruments in solving the problem of environmental protection in the Republic of Serbia. By introducing and implementing economic instruments, we would create the necessary mechanisms for raising funds. The paper will present economic instruments: environmental taxes, environmental fees, subsidies and donations as existing instruments for raising funds. Practice has shown that by applying various economic instruments, we can effectively achieve the set environmental goals. The methods we used in this paper are: analysis, synthesis, statistical method and descriptive method. The data we used in this paper were collected from the Republican Bureau of Statistics and the Environmental Protection Agency. The results of the research show that Serbia needs greater participation of local and national authorities in solving these problems. More needs to be invested in the education of civil servants, a clearer penal policy and the implementation of existing legislation.
Composable Gadgets with Reused Fresh Masks
Authors: Knichel David , Moradi Amir
Published: June 2022

Albeit its many benefits, masking cryptographic hardware designs has proven to be a non-trivial and error-prone task, even for experienced engineers. Masked variants of atomic logic gates, like AND or XOR – commonly referred to as gadgets – aim to facilitate the process of masking large circuits by offering free composition while sustaining the overall design’s security in the d-probing adversary model. A wide variety of research has already been conducted to (i) find formal properties a gadget must fulfill to guarantee composability and (ii) construct gadgets that fulfill these properties, while minimizing overhead requirements. In all existing composition frameworks like NI/SNI/PINI and all corresponding gadget realizations, the security argument relies on the fact that each gadget requires individual fresh randomness. Naturally, this approach leads to very high randomness requirements of the resulting composed circuit. In this work, we present composable gadgets with reused fresh masks (COMAR), allowing the composition of any first-order secure hardware circuit utilizing only 6 fresh masks in total. By construction, our newly presented gadgets render individual fresh randomness unnecessary, while retaining free composition and first-order security in the robust probing model. More precisely, we give an instantiation of gadgets realizing arbitrary XOR and AND gates with an arbitrary number of inputs which can be trivially extended to all basic logic gates. With these, we break the linear dependency between the number of (non-linear) gates in a circuit and the randomness requirements, hence offering the designers the possibility to highly optimize a masked circuit’s randomness requirements while keeping error susceptibility to a minimum.
The Hidden Parallelepiped Is Back Again: Power Analysis Attacks on Falcon
Authors: Guerreau Morgane , Martinelli Ange , Ricosset Thomas , Rossi Mélissa
Published: June 2022

FALCON is a very efficient and compact lattice-based signature finalist of the NIST’s Post-Quantum standardization campaign. This work assesses Falcon’s sidechannel resistance by analyzing two vulnerabilities, namely the pre-image computation and the trapdoor sampling. The first attack is an improvement of Karabulut and Aysu (DAC 2021). It overcomes several difficulties inherent to the structure of the stored key like the Fourier representation and directly recovers the key with a limited number of traces and a reduced complexity. The main part of this paper is dedicated to our second attack: we show that a simple power analysis during the signature execution could provide the exact value of the output of a subroutine called the base sampler. This intermediate value does not directly lead to the secret and we had toadapt the so-called hidden parallelepiped attack initially introduced by Nguyen and Regev in Eurocrypt 2006 and reused by Ducas and Nguyen in Asiacrypt 2012. We extensively quantify the resources for our attacks and experimentally demonstrate them with FALCON’s reference implementation on the ELMO simulator (McCann, Oswald and Whitnall USENIX 2017) and on a ChipWhisperer Lite with STM32F3 target (ARM Cortex M4).These new attacks highlight the need for side-channel protection for one of the three finalists of NIST’s standardization campaign by pointing out the vulnerable parts and quantifying the resources of the attacks.
SIKE Channels

Published: June 2022

We present new side-channel attacks on SIKE, the isogeny-based candidate in the NIST PQC competition. Previous works had shown that SIKE is vulnerable to differential power analysis, and pointed to coordinate randomization as an effective countermeasure. We show that coordinate randomization alone is not sufficient, because SIKE is vulnerable to a class of attacks similar to refined power analysis in elliptic curve cryptography, named zero-value attacks. We describe and confirm in the lab two such attacks leading to full key recovery, and analyze their countermeasures.

A Educação Física escolar (EFE) proporciona aos alunos uma série de conhecimentos para sua formação que vão desde aspectos biodinâmicos até socioculturais. Nesta esteira, as lutas surgem como conteúdo no arsenal dos docentes. O objetivo geral desta pesquisa foi discutir junto à literatura aproximações e distanciamentos entre a EFE e o Budō (artes marciais japonesas). Os objetivos específicos se resumiram em: I) conceituar a EFE; e II) identificar possíveis propostas entre EFE e o Budō. Como metodologia, fez-se uma análise qualitativa de revisão de literatura no material disponível nas bases de dados Google Acadêmico e Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) do Brasil, os quais revelaram livros, artigos, dissertações e teses à investigação. Concluiu-se que o Budō desenvolve várias capacidades motoras e fisiológicas nos alunos (força, flexibilidade, equilíbrio, etc.), mas também possui potencial para o desenvolvimento de diversos aspectos internos, incluindo benefícios para a autoconfiança, foco mental, equilíbrio emocional e ampliação da visão de mundo do praticante advinda do contato com os ricos elementos culturais dessas práticas (incluindo estética, valores e filosofias da Ásia). Portanto, configura-se como um conteúdo interessante para o docente utilizar em suas aulas.

The importance of a laboratory physics workshop in the formation of the foundation of scientific knowledge in the development of a physics course is well known. The recently changed conditions for training specialists with an updated register of goals and objectives required a revision of methodological approaches in the organization of the educational process. In this regard, the laboratory physical practice has also undergone significant changes. In the example of a laboratory workshop on optics, possible ways of its improvement, taking into account new educational realities, are shown.

The article discusses communication, collaboration and leadership, reflectivity and creativity, and other professional competencies that are important and relevant in teaching. The most important task of preparing an effective teacher is not only personal development of a teacher, but also a fundamental condition for an effective teaching and educational process.
POSTHUMANISM: ALTERNATIVE REALITIES AND AI IN SCIENCE FICTION BY G. EGAN AND R. MORGAN: POSSIBLE IMPACTS OF DIGITAL TECHNOLOGIES ON SOCIETY AND HUMAN NATURE
Authors:   niversity of Rome, Humanities Department, Boyarkina I.
Published: June 2022

The paper focuses on the science fiction novels Permutation City and Quarantine by Greg Egan and analyses his ideas on how life-altering technologies and life-simulating sciences are transforming human life, our consciousness, and our understanding of concepts, such as human/non-human, ecology, and the world around us. The paper studies the way Egan explores the themes of posthumanism, simulated realities, and digital immortality, through the prism of various ethical, social, philosophical, ecological and other problems that these concepts inevitably generate. The rich scientific background of these hard sf novels is analysed. The author also analyses Altered Carbon by Morgan, and compares it to the works of Greg Egan.

The aim of the study is the synthesis and testing for pesticidal activities of 2,3-dimethoxy-16,16-dimethyl-D-homo-8-azagona-1,3,5 (10),13-tetraene-12,17а-one and 2,3-dimethoxy-16,16-dimethyl-d-homo-8-azagona-1,3,5(10),13-tetraene-12-imino-17а-one hydrochloride which could become the basis of plant protection products. The first compound was obtained by condensation of 6,7-dimethoxy-2,3-dihydroisoquinoline with 2-acetyl-5.5-dimethylcyclohexane-1,3-dione. The second substance was synthesized by interaction of the first with ammonium chloride. The synthesized compounds were tested for certain types of pesticide activities. Both synthesized compounds showed herbicidal activity against amaranthus retroflexus, brassica rapa, abutilon theophrasti and insecticidal activity against toxoptera graminum. Hydrochloride 2,3-dimethoxy-16,16-dimethyl-D-homo-8-azagon-1,3,5(10),13-tetraene-12-imino-17a-one showed insecticidal activity against musca domestica and fungicidal activity against drechslera.

The study of the effects and mechanisms of action of therapeutic doses of proton radiation on the body is an important task of biomedicine and radiobiology. One of the mechanisms of action of ionizing radiation is oxidative stress. The MTT test method has found practical application. In our study, the MTT test method was used to analyze oxidative stress after proton irradiation at a dose of 10 Gy, and also revealed a critical period of ontogenesis on the example of Daphnia magna. There is a significant decrease in metabolic activity compared to the control in cells of D. magna irradiated during the juvenile and pubertal periods of ontogenesis, especially at 1- and 2-day-old age. The survival rate of all experimental groups of D. magna does not decrease in comparison with the control, regardless of the duration of irradiation.
