Abnormal production of reactive oxygen species (ROS) is an undesirable event which occurs in plants due to stress. To meet this event, plants synthesize ROS-neutralizing compounds, including the non-enzymatic oxidant scavenger known as vitamin C: ascorbic acid (AsA). In addition to scavenging ROS, AsA modulates many vital functions in stressed or non-stressed plants. Thus, two-season (2018/2019 and 2019/2020) trials were conducted to study the effect of integrative treatment (seed soaking + foliar spray) using 1.0 or 2.0 mM AsA vs. distilled water (control) on the growth, seed yield, and oil yield of parsley plants under three sowing dates (SDs; November, December, and January, which represent adverse conditions of late sowing) vs. October as the optimal SD (control). The ion balance, osmotic-modifying compounds, and different antioxidants were also studied. The experimental layout was a split plot in a completely randomized block design. Late sowing (December and January) noticeably reduced growth traits, seed and oil yield components, and chlorophyll and nutrient contents. However, soluble sugar, proline, and AsA contents were significantly increased along with the activities of catalase (CAT) and superoxide dismutase (SOD). Under late sowing conditions, the use of AsA significantly increased growth, different yields, essential oil fractions, CAT and SOD activities, and contents of chlorophylls, nutrients, soluble sugars, free proline, and AsA. The interaction treatments of SDs and AsA concentrations indicated that AsA at a concentration of 2 mM was more efficient in conferring greater tolerance to adverse conditions of late sowing in parsley plants. Therefore, this study recommends 2.0 mM AsA for integrative (seed soaking + foliar spraying) treatment to prolong the sowing period of parsley seeds (from October up to December) and avoid damage caused by adverse conditions of late sowing.

Water availability is a crucial factor in the final productivity of cowpea. The objective of this work was to evaluate the production and productivity components of cowpea under different irrigation depths in Amazonian conditions. The experiment was carried out at the School Farm of the Federal Rural University of Amazonia, in the municipality of Castanhal-PA, using the cultivar BR3 Tracuateua, from September to November 2014, 2015, and 2016. The experimental design was conducted on six blocks and four treatments, where the four irrigation depths of 0, 25, 50, and 100% of crop evapotranspiration were tested. The productivity analysis was performed when 90% of the plants were in the phenological stage R9. The evaluated production components were pod length, number of pods per plant, number of grains per pod, mass of one hundred grains, and harvest index. There was a statistical difference among all treatments for the components of production and among productivities. An average reduction of 827 kg ha−1 in cowpea productivity was observed during the three years of study, when the treatment without irrigation was compared with the treatment irrigated with 100% of the crop’s water demand. It was found in this research that the simple fulfillment of the nutritional and phytosanitary demands of the crop, associated with an adequate planning of when to plant in the region, would already help in the improvement of local production when choosing times where the water deficit in the reproductive phase is less than 33 mm.

Published: April 2022

This research was designed to provide the first protocol to establish an efficient solution for direct organogenesis regeneration in Passiflora quadrangularis using nodal explants from young shoots. Passifloraceae tissue culture has been associated with problems such as recalcitrance, sensitivity to ethylene accumulation and browning of explants due to the presence of phenols in the tissues. Due to the high rate of endogenous contamination of the explants, a preliminary experiment was performed. The best results of surface sterilization were obtained using the pretreatment with 70% EtOH, 1 min and 50% NaOCl, 10 min along with the treatment of Rifampicin 15 µg/mL and Benomyl 2 g/L. The effects of plant growth regulators on the induction of direct organogenesis, multiplication of shoots in subcultures and in vitro rooting were evaluated. Additional compounds such as AgNO3 and Pluronic F-68 were added to the culture media in order to reduce the effects of phenols and the sudden browning of the explants. Shoot proliferation increased to the sixth subculture after which it decreased. A maximum of 7.17 shoots were obtained from one shoot on Murashige and Skoog (MS) medium supplemented with 2 mg/L 6-benzylaminopurine and 1 mg/L thidiazuron. Supplementation of ½ MS medium with 1 mg/L 1-naphthaleneacetic acid was conducing to root formation in 61.11% of shoots. After acclimatization, the plants showed vigorous growth, green leaves, and well-developed roots. Although this species has previously shown difficulty in in vitro propagation, this protocol established based on the results proved to be efficient and reproducible.

The aim of this study was to investigate the catechin levels and antioxidant activities as manipulated by roasting temperature and roasting time of green tea. Roasting temperature and time varied between 100–300 °C and 60–240 s in green tea production. The main interactions measured were effects on the antioxidant activities, total phenolic content, DPPH, ABTS, FRAP and catechin content (catechin (C), epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG) and epicatechin (EC)). Optimum roasting conditions were determined as 270 °C for 240 s, since this enabled high catechin contents, antioxidant activities and production yield. The extraction methods for green tea including traditional extraction (TDE), microwave-assisted extraction (MAE) and ultrasonic-assisted extraction (UAE) using 60% ethanol as solvent were investigated to evaluate the highest bioactive compound and yield of extraction. MAE was found to be more efficient in green tea extraction compared to UAE and TDE. The extracts showed significant cytotoxic potential against the Huh-7 cell line, in concentrations ranging from 31.25 to 1000 µg/mL. The results are useful in understanding the relationship between thermal treatment and extraction conditions on the chemical and nutritional properties of tea catechins, making it possible to select the production and extraction conditions that maximize the levels of beneficial tea ingredients.

Published: April 2022

Ciprofloxacin (CIP) in natural waters has been taken as a serious pollutant because of its hazardous biological and ecotoxicological effects. Here, a 3D nanocomposite photocatalyst g-C3N4/La-N-TiO2 (CN/La-N-TiO2) was successfully synthesized by a simple and reproducible in-situ synthetic method. The obtained composite was characterized by XRD, SEM, BET, TEM, mapping, IR, and UV-vis spectra. The photocatalytic degradation of ciprofloxacin was investigated by using CN/La-N-TiO2 nanocomposite. The main influential factors such as pH of the solution, initial CIP concentration, catalyst dosage, and coexisting ions were investigated in detail. The fastest degradation of CIP occurred at a pH of about 6.5, and CIP (5 mg/L starting concentration) was completely degraded in about 60 min after exposure to the simulated solar light. The removal rates were rarely affected by Na+ (10 mg·L−1), Ca2+ (10 mg·L−1), Mg2+ (10 mg·L−1), and urea (5 mg·L−1), but decreased in the presence of NO3− (10 mg·L−1). The findings indicate that CN/La-N-TiO2 nanocomposite is a green and promising photocatalyst for large-scale applications and would be a candidate for the removal of the emerging antibiotics present in the water environment.

Published: April 2022

Background: Stroke is the leading cause of death in China, and its burdens are rapidly increasing. The prevalence and control of stroke risk factors among stroke patients in China are unknown. Objective: We investigated the stroke risk factors of stroke patients in China. Design: We examined stroke risk factors in 6580 stroke patients aged 18 years or older in the China National Chronic Diseases and Nutrition Surveillance of Adults (2015–2017). With regard to the basic characteristics of the study participants, categorical variables were described as frequency (percent). The chi-square test was used to analyze the difference between men and women. The multivariate logistic regression model was used in the multivariate analysis. Results: Among the 6580 stroke patients, hypertension was the most common stroke risk factor identified in most cases (78.51%), followed by overweight or obesity (61.58%), dyslipidemia (54.38%), smoking (24.04%), diabetes (21.75%), family history of stroke (17.43%), lack of exercise (16.35%), and atrial fibrillation (4.47%). Drinking stroke patients had a lower rate of hypertension, diabetes, and dyslipidemia. Patients with hyperuricemia had a higher rate of hypertension and dyslipidemia than no-hyperuricemia patients. The hypertension awareness, treatment, and control rates among hypertension stroke patients were 73.62%, 70.19%, and 17.79%, respectively. The diabetes awareness, treatment, and control rates among diabetes patients were 69.74%, 65.83%, and 34.59%, respectively. The dyslipidemia awareness, treatment, and control rates among dyslipidemia patients were 42.37%, 29.4%, and 20.07%, respectively. Among treated hypertension patients, the rates of taking medicine as medically advised, controlled diet, increased exercise, and blood pressure monitoring were 91.31%, 58.88%, 45.78%, and 73.99%, respectively. Among treated diabetes patients, the rates of oral antidiabetic medications, insulin injection, diet control, and blood glucose monitoring were 78.24%, 34.71%, 85.77%, and 78.24%, respectively. Among treated dyslipidemic patients, the rate of taking medicine as medical advice, controlled diet, increased exercise, and regular blood lipid monitoring was 80.61%, 77.57%, 56.46%, and 40.3%, respectively. Conclusions: The most common risk factors for community stroke patients in China are hypertension, dyslipidemia, and overweight or obesity. The stroke community patients’ suboptimal awareness and treatment of hypertension, and suboptimal awareness, treatment, and control of diabetes, and dyslipidemia are significant problems in China.
Fit for Purpose—Re-Designing Australia’s Mental Health Information System
Authors: Rosenberg Sebastian , Salvador-Carulla Luis , Meadows Graham , Hickie Ian
Published: April 2022

Background: Monitoring and reporting mental health is complex. Australia’s first National Mental Health Strategy in 1992 included a new national commitment to accountability and data collection in mental health. This article provides a narrative review of thirty years of experience. Materials and Methods: This review considers key documents, policies, plans and strategies in relation to the evolution of mental health data and reporting. Documents produced by the Federal and the eight state and territory governments are considered, as well as publications produced by key information agencies, statutory authorities and others. A review of this literature demonstrates both its abundance and limitations. Results: Australia’s approach to mental health reporting is characterised by duplication and a lack of clarity. The data available fail to do justice to the mental health services provided in Australia. Mental health data collection and reporting processes are centrally driven, top–down and activity-focused, largely eschewing actual health outcomes, the social determinants of mental health. There is little, if any, link to clearly identifiable service user or carer priorities. Consequently, it is difficult to link this process longitudinally to clinical or systemic quality improvement. Initial links between the focus of national reform efforts and mental health data collection were evident, but these links have weakened over time. Changes to governance and reporting, including under COVID, have made the task of delivering accountability for mental health more difficult. Conclusion: Australia’s current approach is not fit for purpose. It is at a pivotal point in mental health reform, with new capacity to use modelled data to simulate prospective mental health reform options. By drawing on these new techniques and learning the lessons of the past, Australia (and other nations) can design and implement more effective systems of planning, reporting and accountability for mental health.
Effects of Alkali on Water Soluble Hexavalent Chromium in Ordinary Portland Cement

Published: April 2022

Due to the toxicity and mobility of chromium, the disposal of chromium-containing waste is a pressing issue. Co-processing of chromium-containing waste in a cement kiln is currently one of the most effective methods. However, the presence of water-soluble hexavalent chromium (Cr(VI)) in cement limits the use of this method. In this study, Na2CO3 was used to simulate alkali in industrial raw materials to investigate the pattern of influence of alkali content on water-soluble hexavalent chromium. The mechanisms associated with the oxidation and dissolution of chromium were investigated using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma emission spectrometry (ICP-OES). The proportion of Cr(VI) in the clinker detected by XPS increased rapidly with increasing alkali content. In the cement slurry system, alkali promotes more hexavalent chromium leaching by influencing pH and other ion concentrations (Ca2+, SO42−). Therefore, the addition of alkali to either the raw meal or to the cement slurry system will favour an increase in the water-soluble Cr(VI) content. This study may provide theoretical guidance for the preparation and use of clinkers containing chromium.

Published: April 2022

Vitiligo is described as a dermatological condition characterized by pigmentation disorders in both the skin and mucous membranes. Clinically, this disease is characterized by the presence of well-defined white areas of various shapes and sizes, which are a manifestation of a reduced number of melanocytes. Due to the fact that vitiligo can be a significant cosmetic problem for patients, a number of methods are currently available to help fight for a better skin appearance. If all the available non-invasive procedures turn out to be ineffective, surgery can help, which is a very good alternative in the case of difficult-to-treat but stable changes. Both the development of new techniques and modifications to the already available treatment of cell and tissue transplantation give hope to numerous patients around the world. The effectiveness of a particular method is determined by its appropriate selection depending on the lesions undergoing therapy. Each form of surgical intervention has its advantages and disadvantages, which, along with the location or size of the treated hypopigmentation area, should be analyzed by a doctor and discussed with their patient. This article is an overview of the currently available methods of surgical treatment of vitiligo and a comparison of their pros and cons.

Transculturación en la clave cubana: la permanencia del soporte de comunicación frente a la colonización de la escritura musical
Authors: Farías Vásquez Miguel , Bulicic Auspont Tamara
Published: April 2022

Al entender la música como un tipo de enunciación y, en consecuencia, un tipo de escritura, se plantea la revisión del proceso hegemónico por el cual ésta, a su vez entendida como un sistema de soportes de comunicación, fue también colonizada. Dado que diversos sistemas de soportes, registros y comunicación fueron foco de atención para el proceso de colonización en América, se infiere que la música también lo fue, tanto en su dimensión ideológica como tecnológica. Para definir esto, en el presente trabajo se emplea el concepto de solfeización en su validación de la partitura como estructura y articuladora principal de la teoría musical occidental, en contraposición con el caso de estudio de la música afrocubana, en específico el de la clave cubana: estructura rítmica que ordena gran parte de la música de esta tradición. Así, proponemos tal elemento como un indicador de que lo ideológico en la música no fue totalmente colonizado en la región de América Latina.
Modernizaciones agropecuarias en Argentina. Fijos y flujos en el circuito espacial de producción y transformación de granos
Authors: Maldonado Gabriela Inés
Published: April 2022

La modernización agropecuaria, entendida como el proceso en el cual se incorporan datos centrales del periodo histórico vigente, se encuentra representada hoy por la expansión del modelo de agronegocios y se sustenta en la consolidación de sistemas de infraestructura y topologías empresariales que determinan la forma en la que el territorio es usado. Analizaremos en esta oportunidad el proceso de modernización agropecuaria a través de la red de fijos y flujos que dinamizan esta actividad. Entre los primeros, nos interesa observar los sistemas de ingeniería que permiten el transporte de granos tanto en la región pampeana como en las áreas de expansión de la agricultura moderna, la red de acopios de granos, la estructura comercial vinculada a la distribución de insumos agropecuarios y la estructura industrial vinculada a la transformación de granos. Con relación a los flujos, nos interesa observar los porcentajes de granos producidos y transportados y especialmente reconocer la distribución territorial de especializaciones productivas que explican tales flujos, específicamente: áreas de extracción de la producción, áreas de transformación industrial, áreas de acopio y exportación. Todo lo anterior estará atravesado por el análisis del circuito espacial de producción agrícola y el escrito se detendrá en algunos estudios de caso representativos del sur de Córdoba.
A lo largo de lo rural y lo urbano. Experiencias de movilidad territorial en perspectiva histórica (Gran Buenos Aires, 1930-2020)
Authors: Hendel Verónica
Published: April 2022

En este artículo analizamos las movilidades rurales que atraviesan y dan forma a las trayectorias socio-educativas de jóvenes y adultos que estudian y/o viven en un barrio del conurbano bonaerense (Argentina) desde un enfoque analítico que se vale de los aportes de los estudios migratorios y de los estudios de la movilidad, así como de la etnografía. Para ello construimos un estudio de caso sobre el barrio Carlos Mugica, también conocido como Ejército de los Andes y Fuerte Apache, que nos permite aproximarnos a las múltiples movilidades rurales que atraviesan e inciden sobre su pasado y su presente. Entre los resultados de la investigación es posible señalar que: las movilidades rurales se diversifican y tornan más heterogéneas, tanto por sus características y temporalidades como por su devenir histórico; la experiencia de lo urbano se encuentra atravesada por una experiencia previa de lo rural que sigue latente en la ciudad e incide sobre los modos de habitarla; el movimiento implica la posibilidad de desarrollar una mirada atenta a las transformaciones de los lugares a lo largo de los cuales se despliega; y, por último, que las experiencias escolares aparecen como una referencia importante, tanto por las oportunidades que la misma brinda como por las tensiones y marcaciones que allí se experimentan.

Published: April 2022

Este artigo tem como objetivo analisar padrões de viagem de forma desagregada, observando as características dos deslocamentos de homens e mulheres. A Região Metropolitana do Rio de Janeiro (RMRJ) foi escolhida como objeto de estudo, sendo utilizados dados de deslocamentos provindos da pesquisa origem destino realizada em 2003. A metodologia desenvolvida baseou-se em análises descritivas das variáveis de interesse e do cruzamento dos dados de sexo e situação familiar. Os resultados apontam para um padrão de deslocamento distinto: homens com número de viagens, duração e distância de deslocamento com magnitudes superiores em relação às mulheres. Entretanto, quando analisado o modo de transporte, elas possuem o que pode ser chamado de um comportamento mais sustentável, por dependerem mais fortemente do transporte coletivo e ativo em suas viagens. Para o planejamento de transporte, o conhecimento do comportamento e das necessidades dos grupos de interesse pode auxiliar no momento de definição de políticas específicas e no emprego racional dos recursos públicos a fim de construir uma cidade igualmente acessível e justa para todos seus habitantes.

El principal método de mejoramiento genético en gerbera (Gerbera hybrida) es por hibridación y posterior selección. En México todas las variedades comerciales son importadas, lo que hace costosa su producción. El objetivo de esta investigación fue analizar la variación morfológica de 24 híbridos de gerbera obtenidos a través de cruzas intraespecíficas entre seis cultivares comerciales e identificar las variantes promisorias. Los híbridos se establecieron en invernadero en un diseño completamente al azar. Se evaluaron en plena floración mediante 44 descriptores propuestos por la Unión Internacional para la Protección de las Obtenciones Vegetales (UPOV). Se realizó análisis de varianza y análisis multivariados de agrupamiento, componentes principales y discriminante. Los híbridos mostraron el 65 % de las categorías que cubren la variación total de los descriptores empleados, con diferencias altamente significativas (P ≤ 0.01) en variables cuantitativas e índices de 0.6 promedio entre valores extremos (menor/mayor); el diámetro del capítulo correlacionó positiva y significativamente con el ancho de la hoja (r = 0.54, P ≤ 0.01) y con la longitud del pedúnculo (r = 0.47, P ≤ 0.05). Se observaron 23 tonalidades en el color interno de la lígula exterior, así como los tres tipos de capítulo (sencillo, semidoble y doble). En un fenograma, con coeficiente de identidad promedio de 0.712 hubo separación de los híbridos en cinco grupos con distancias comprendidas entre 0.3 y 0.66. Los tres primeros componentes principales explicaron el 66 % de la varianza total, y las variables con mayor aporte correspondieron al capítulo floral. El análisis discriminante agrupó a los híbridos principalmente por las variables largo y ancho de la hoja, longitud de pedúnculo y diámetro del capítulo. Se identificaron híbridos con potencial comercial para flor de corte y de maceta, propagables mediante clonación in vitro.

Las royas han sido uno de los mayores problemas del trigo (Triticum spp.) en el mundo, de las cuales, la de la hoja, causada por el hongo Puccinia triticina, es la más común y la más ampliamente distribuida. El uso de variedades resistentes es el método más efectivo y ecológicamente sustentable para su control. El objetivo de este trabajo fue postular los genes de resistencia a roya de la hoja en plántula de genotipos élite y su respuesta a la enfermedad en planta adulta. Se evaluaron 38 genotipos del grupo de progenitores del Programa de Trigo del INIFAP-CEVAMEX, incluyendo variedades y líneas experimentales. Se inocularon 16 razas diferentes de roya de la hoja bajo condiciones de invernadero para ser evaluados en estado de plántula, y la raza MBJ/SP para medir su respuesta en planta adulta en campo e invernadero. Con base en los tipos de infección expresados por los genotipos en estado de plántula, se postuló la presencia de 14 genes: Lr1, 2a, 2c, 3, 9, 10, 13, 14b, 16, 17, 23, 24 y 27+31, solos o en combinación de hasta ocho, teniendo un total de 31 combinaciones diferentes; así mismo, hubo variación en la respuesta en planta adulta. Se identificaron genotipos que combinan genes de resistencia en plántula y planta adulta, presentando mayor resistencia en planta adulta los genotipos de reciente formación, lo que refleja los avances en el mejoramiento mediante la acumulación de genes para el control genético de la roya de la hoja.

En los últimos años se ha observado un incremento de plantas con senescencia retardada del tallo de soya (Glycine max L. Merr.) en la región sur de Paraguay, sin que se haya estudiado el origen de este fenómeno. Bajo la hipótesis de que la senescencia retardada del tallo de soya está influenciada por la relación fuente/demanda, el objetivo del presente estudio fue evaluar el efecto de la eliminación de vainas sobre la senescencia retardada del tallo de la soya. El experimento se realizó en condiciones de campo en las temporadas 2016/2017 y 2019/2020 en los distritos Tomás Romero y Carlos Antonio López, respectivamente, ambas en el Departamento de Itapúa, Paraguay. El diseño experimental utilizado fue de bloques completos al azar con seis tratamientos y cuatro repeticiones. Los tratamientos fueron los porcentajes de retención de las vainas de 0, 20, 40, 60, 80 y 100 %. En inicio de formación de semillas (R5) se cuantificó número de vainas y se eliminaron manualmente de acuerdo con los porcentajes correspondientes a cada tratamiento. Las variables evaluadas fueron el número de hojas retenidas por planta, porcentaje de tallos verdes, porcentaje de vainas verdes, peso de 100 granos, humedad de granos y rendimiento. Al disminuir los niveles de retención de vainas aumentan la cantidad de hojas retenidas, el porcentaje de tallos y vainas verdes y el peso de 100 granos. El rendimiento aumenta con una tendencia cuadrática a medida que se incrementa el porcentaje de vainas retenidas.

En esta investigación se evaluó el efecto por separado de cinco sales minerales en la conservación de dos cultivares de lisianthus (Eustoma grandiflorum). Para ello, inflorescencias de las variedades ABC Blue Rim y Mariachi Carmine se colocaron por 12 h en soluciones de nitrato de calcio 0.1 %, cloruro de cobalto 0.2 mM, sulfato de aluminio 100 mg L-1, ácido bórico 100 mg L-1, cloruro de níquel 0.5 mM y agua destilada como control. Se evaluó el consumo de agua, peso fresco relativo y respiración durante su vida en florero. El nitrato de calcio y el sulfato de aluminio incrementaron el consumo de agua en las inflorescencias de Mariachi Carmine (25-31 mL/ tallo) y ayudaron a mantener valores más altos y por más tiempo de peso fresco relativo en ambos cultivares (96.9 % por 9-11 días). Estos compuestos también disminuyeron la tasa respiratoria de las inflorescencias de ABC Blue Rim y Mariachi Carmine en 45-67 y 51-59 %, respectivamente. Los resultados sugieren que estas sales preservaron las relaciones hídricas y la función de los tejidos conductores en las dos variedades, lo cual, aunado a las tasas respiratorias más bajas, mejoraron significativamente la vida en florero de lisianthus.

The present study analyzed the reliability and factor structure of the Brazilian Math Anxiety Scale, as well as item parameters assessed by Rasch analysis. The Scale was applied to high school students from a public school in the countryside of Pará through an online form. The scale showed good reliability (α = 0.947), and a two-factor structure, preliminarily identified as Numerical Anxiety and Anxiety to Math Assessment. The items of the factor Anxiety to Math Assessment showed higher mean and lower difficulty than the items of the factor Numerical Anxiety. Girls showed higher scores than boys (d = 0.72). These results suggest that the Scale is reliable, robust, and able to capture the latent structure of the Math Anxiety construct.

The unconsolidated earth surface is a rich source of minerals, of which clay is one of the richest natural minerals, having various natural and anthropogenic properties. Natural clay is widely available as a cheaper resource, which is non toxic to ecosystems and has the property of preserving ground water and aquifers. At the same time, the ubiquitous and widespread occurrence of clay will have the property to control toxic materials. The uncontrolled exploitation or mining of clay minerals will affect the aquatic ecosystem's sustainability in many ways. Water quality is very essential for the healthy environment and human life, whereas unpredictable conditions like flooding, drought, groundwater loss, loss of biodiversity, and health impacts on the surrounding inhabitants are some of the signs of ecosystem loss. The unwanted mined clay is deposited into the surrounding area of the mining environment, resulting in top soil, ground water, and surface water pollution. The review paper describes the pollution aspects of the aquatic ecosystem with special emphasis on ground water, aquifers, fresh water (lotic and lentic), sediment, and marine ecology and hydrology.

Mobile devices have several sensors, including GPS that can capture information about the location of a mobile user. The use of certain devices will, therefore, simplify services and make it simpler for operators to respond to the demands of mobile users. The main aim of this analysis is to incorporate middleware to pick suitable cloud services that leverage from mobile device position and cost preferences. If the number of small activities within a meta feature exceeds the number of major work, the Max min algorithm device operations are conducted in addition to big tasks, where the design of the process is dependent on how many functions it does. The model is wide since tasks cannot be conducted simultaneously. A new amendment to the computation system is used to overcome the drawbacks of the Max-Min algorithm. It encompasses the positives of Max-Min and eliminates drawbacks. This study focuses specifically on the number of resources and incidents. The work can be further expanded with the algorithm suggested for the cloud system and several other parameters such as scalability, performance, reliability, and others can be taken into account.

In this work, we examine the potential of Physical Unclonable Functions (PUFs) that have been implemented on NAND Flash memories using programming disturbances to act as sustainable primitives for the purposes of lightweight cryptography. In particular, we investigate the ability of such PUFs to tolerate temperature and voltage variations, and examine the current shortcomings of existing NAND-Flash-memory PUFs that are based on programming disturbances as well as how these could potentially be addressed in order to provide more robust and more sustainable security solutions.

This work was accepted for and presented at the Workshop on Sustainability in Security, Security for Sustainability, which took place on 18 March 2022 and was co-located with the 25th Design, Automation and Test in Europe Conference & Exhibition (DATE 2022).
How to respond to emerging threats of cyberspace security via social engineering? A novel paradigm to solve cyberspace security issues
Authors: Lin Hao
Published: April 2022

Cybersecurity researchers always ignore the “people” behind the issues when dealing with cyberspace security issues. The human
and technological aspects of cyberspace security must be simultaneously addressed to enable a secure cyber environment. Social
engineering is a discipline whose research object is people, and the combination of social engineering and cyberspace security can
provide new solution ideas for lots of cyberspace security issues. This paper attempts to answer the question —— “How to solve
cyberspace security issues via social engineering?” We briefly review existing frameworks for social engineering attacks and pro?pose a novel, recursive, and iterative framework for social engineering attacks in cyberspace. The existing research achievements
of combination of social engineering and cyberspace security were reviewed in the order of cyber personality, hacker psychology,
human flesh search, and social engineering defense. To answer this question, we summarized four “guidelines” for using social
engineering. Finally, we look ahead, give our thoughts, and discuss answers of the question and future research. It is aimed at
getting more researchers of cyberspace security and social science to pay attention to this field.

A Multi-Scale Simulation Study of the Structural Integrity of Damascene Interconnects in Advanced Technology Nodes
Authors: Mukesh Sagarika
Published: April 2022

The structural stability of damascene inter-
connects for back-end-of-line (BEOL) technologies is an-
alyzed using a combination of force-field based molecu-
lar dynamics simulations and finite-element modeling. The
candidate metals analyzed are- ruthenium, cobalt, tung-
sten, and copper. Cohesive traction and normal bonding
energy are calculated using force-field based molecular
dynamics simulations and then fed as input to a finite-
element analysis (FEA) tool, where their dependence on
physical dimensions of the interconnect lines is studied.
The characteristics of these metals are compared against
the characteristics of copper. The parameters studied for
the BEOL structures are sidewall angle, aspect ratio, inter-
nal stress of the metal, and modulus of elasticity of the di-
electric material around the metal at 18 nm pitch. Generally,
lower aspect ratio and higher modulus of elasticity of the
dielectric results in structures that show a lower tendency
to collapse. Intrinsic stress of the metal and side wall angle
have a minor impact on the overall stability. Based on this
study, cobalt is most stable alternate metal amongst Ru, Co,
and W.
Energy-Efficient Implementation of Generative Adversarial Networks on Passive RRAM Crossbar Arrays
Authors: Sahay Shubham , Nikam Honey , Satyam Siddharth
Published: April 2022

Generative algorithms such as GANs are at the cusp of next revolution in the field of unsupervised learning and large-scale artificial data generation. However, the adversarial (competitive) co-training of the discriminative and generative networks in GAN makes them computationally intensive and hinders their deployment on the resource-constrained IoT edge devices. Moreover, the frequent data transfer between the discriminative and generative networks during training significantly degrades the efficacy of the von-Neumann GAN accelerators such as those based on GPU and FPGA. Therefore, there is an urgent need for development of ultra-compact and energy-efficient hardware accelerators for GANs. To this end, in this work, we propose to exploit the passive RRAM crossbar arrays for performing key operations of a fully-connected GAN: (a) true random noise generation for the generator network, (b) vector-by-matrix-multiplication with unprecedented energy-efficiency during the forward pass and backward propagation and (C) in-situ adversarial training using a hardware friendly Manhattan's rule. Our extensive analysis utilizing an experimentally calibrated phenomological model for passive RRAM crossbar array reveals an unforeseen trade-off between the accuracy and the energy dissipated while training the GAN network with different noise inputs to the generator. Furthermore, our results indicate that the spatial and temporal variations and true random noise, which are otherwise undesirable for memory application, boost the energy-efficiency of the GAN implementation on passive RRAM crossbar arrays without degrading its accuracy.
Resampling, Relabeling, & Raking Algorithm to One-Class Classification
Authors: Im Jongho , Lee Hae-Wwan , Park Seunghwan
Published: April 2022

The performance of a classification model significantly depends on the degree to which the support of each data class overlaps. Successfully distinguishing classes is difficult if the support is similar while classes differ. In the one-class classification (OCC) problem, wherein the data comprise only a single class, classifier performance is significantly degraded if the population support of each class is similar. In this study, we propose a preprocessing algorithm that enhances classifier performance by utilizing macro information that is most easily obtainable in these two problem situations. The algorithm aims to improve classifier performance by reprocessing the given data into data with mitigated class imbalance through raking and sampling techniques. This improvement in performance is demonstrated by comparing representative classifiers used in the existing OCC problem with traditional binary classifier models, unavailable on the single-class dataset.
Occurrence of Odor and Suggestions for a Comprehensive Management System in Ulsan, South Korea
Authors: Choi Sung-Deuk
Published: April 2022

In Ulsan, large-scale industrial facilities emit large amounts of various odors and hazardous air pollutants. This study investigated the current status of odor problems in Ulsan and suggested a comprehensive management system. Owing to the geographical conditions, weather conditions, major industrial complexes, and management of emission facilities, complaints about odor occur mainly in summer. The city authority responds to odor problems by preparing comprehensive measures to prevent odors and introducing unmanned sampling devices, real-time monitors, and a mobile monitoring system. Major odor substances and pollution characteristics can be identified through these efforts, but information on specific odor substances, complex odors, emission sources, and transport pathways is lacking. Therefore, it is necessary to upgrade the current monitoring system and establish a comprehensive management system to solve this problem.
