Managing the financial impact of cybersecurity incidents
Authors: Bederna Zsolt , Szádeczky Tamás
Published: February 2023

The complex relationships of economic actors and the high dependency on information and communication technologies make it necessary for all relevant entities to develop protection. This protection should include preventive and reactive controls in a risk-proportionate manner in relation to the business value protected. We aimed to develop a solution to support cybersecurity-related business decisions with financial analytics. The risk-based approach helps management find the optimum solution with minimal costs, where protection prevents some incidents from occurring, while the risks associated with other incidents are accepted in an informed way. The security industry developed a number of apparatuses to find the optimum security controls that enforced the fiscal aspects, which typically contain solutions used in planning. However, the actual expenditure often differs from the planned budget for several reasons, one of which is
the occurrence of security incidents. We used the common methodology toolset for financial analysis (NPV, NFV, risk assessment). We developed novel metrics based on these that can be used in cybersecurity management. Within the framework thus defined, the article discusses the economic context of the effects of incidents involving Meta (previously Facebook) services from 2016 to 2020. This paper introduces the ‘Effect of incidents’ metric to measure the impact of unplanned incidents’ on actual expenditure compared to the planned budget and the ‘Incidence of incident recognition’ metric to measure deviations of an incident’s impact as perceived by owners relative to the effect on the value of the assets. The paper also proves the applicability of those metrics using the example of Meta.

Authors: Monsalve Alberto
Published: February 2023

Un tema de permanente investigación en ciencia e ingeniería de materiales es el de los aceros multifásicos, que son aceros que contienen varias fases: ferrita, bainita, martensita y austenita retenida. Cada una de estas fases otorga ciertas propiedades, por ejemplo, la ferrita entrega conformabilidad, la bainita y la martensita, resistencia mecánica y la austenita ductilidad. Esta combinación de propiedades hace posible que el acero multifásico, sea un material de excepcionales propiedades mecánicas. Otro aspecto relevante dice relación con la necesidad de predecir las propiedades mecánicas de este tipo de aceros, las cuales dependerán precisamente de las fases presentes y de las transformaciones que puedan ocurrir durante los procesos de deformación. Se ha investigado acerca de la forma en que dichas propiedades mecánicas pueden ser predichas. El presente artículo muestra algunos de los avances más relevantes que se han hecho los últimos años en la predicción de propiedades mecánicas a partir de modelos constitutivos, contrastándose los resultados de dichos modelos con los valores reales obtenidos experimentalmente, mostrando una buena correspondencia entre ambos valores.

Objetivo: determinar a atividade antinociceptiva, anti-inflamatória e toxicológica da espécie Annona leptopetala. Método: O estudo buscou basear-se em uma triangulação entre abordagens qualitativa-experimental e quantitativa; foram utilizados 72 camundongos, (Mus musculus), albinos, variedade Swiss, adultos jovens e machos, de peso entre 25-30g; os animais foram submetidos à peritonite, teste de formalina, contorções e avaliação da ação tóxica em ratos Rattus Norvegicus provenientes do biotério da Faculdade Santa Maria, Cajazeiras-PB. A pesquisa seguiu em conformidade e foi conduzida em obediência às normas e diretrizes bioéticas vigentes para ensaios envolvendo seres vivos: animais (Guide for the Care and Use of Laboratory Animals, do NIH - National Institute of Health-EUA, 1996; Lei Federal Nº 11.794/2008; Conselho Nacional de Controle de Experimentação - CONCEA); e integridade da fauna e flora (Lei Federal Nº 9605/1998) (MACHADO et al., 2004). O projeto foi aprovado pelo Comitê de Ética em Pesquisa Animal da Faculdade Santa Maria - FSM, com o número 003/2016. Resultados: A pesquisa mostrou que a inibição da nocicepção induzida por formalina foi positiva na dosagem de 200 mg/kg, com redução mínima do tempo de lambedura da pata injetada na primeira fase do teste em 5% e subindo na segunda fase para 40%. Porém, o extrato não apresentou ação significativa no teste anti-inflamatório e não houve detecção de efeitos indesejados nos camundongos. Assim, a Annona leptopetala apresenta potencial terapêutico como antinoceptor (analgésico). O extrato não apresentou toxicidade na dose testada, uma vez que sua administração oral não induz sinais de toxicidade geral ou mortalidade, sugerindo uma segurança terapêutica para as doses farmacologicamente ativas, visto que a utilização deste extrato pode melhorar a função hepática. Além disso, destaca-se como relevância da presente pesquisa a comprovação científica quanto ao uso popular da espécie Annona leptopetala como anti-inflamatória, porém pouco significativa, analgésica e tóxica. Sendo assim, aguarda-se a realização de demais pesquisas para validar os resultados obtidos no estudo e buscar a liberação da mesma para utilização como fármaco. Conclusão: Na avaliação da atividade anti-inflamatória, a substância chegou a apresentar alguma ação, porém não significativa; no entanto, a nocicepção induzida por formalina foi positiva para a amostra de Annona leptopetala. Relacionando-se à avaliação da toxicidade aguda, o extrato não apresentou toxicidade, já que sua administração oral não induziu sinais de toxicidade geral ou mortalidade, gerando uma segurança terapêutica para as doses farmacologicamente ativas, melhorando a função hepática, pela diminuição das suas taxas séricas.

Design and fabrication of conversion fiber with double-core structure for photonic integrated circuits high-density interconnect
Authors: Yu Hongli , Yoshimoto Naoto , Fujii Yusuke , Kobayashi Soichi
Published: February 2023

To relax photonic integrated circuits (PIC) and its optical interconnect densification limitations from the standard fiber, we proposed a special fiber with a double core structure, named conversion fiber, which can convert both its spot size and its outer diameter, simultaneously. The simulation in this study clarified that the proposed conversion fiber had more capability of spot size and the outer diameter conversion with a large conversion ratio, as compared with a conventional fiber with a single core structure, and had large tolerance for the refractive index fluctuation. After that, we fabricated a conversion fiber based on the design parameters. The insertion loss of fabricated conversion fiber, including the coupling loss and the excess loss due to the mode conversion was 0.2 dB, which well agrees with the simulation results. From these results, it is expected that the proposed fiber can achieve higher density optical interconnect for PIC.

Published: February 2023

Recently, we directly observed the out-of-plane Dresselhaus spin–orbit (SO) interaction field and extracted the SO coefficient

β

from InGaAs (110) quantum wells (QWs). However, the extracted

β

was much larger than that of the (001) QWs, which yielded an in-plane Dresselhaus SO field. In this study, we perform Monte-Carlo simulations and reproduce the results of time-resolved and spatiotemporally resolved Kerr rotation measurements in InGaAs (110) QWs. The results conclusively show that InGaAs (110) QWs have a strong out-of-plane Dresselhaus SO field as compared with (001) QWs.

Axis thermal expansion switching in transition-metal zirconides TrZr2 by tuning the c/a ratio
Authors: Arima Hiroto , Riad Kasem Md. , Mizuguchi Yoshikazu
Published: February 2023

This study examines the temperature-dependent evolution of the lattice constants for various CuAl2-type compounds, including NiZr2, (Co,Rh,Ir)Zr2, (Fe,Co,Rh,Ir)Zr2, and (Co,Ni,Cu,Rh,Ir)Zr2, in the pursuit of negative or zero thermal expansion. Results reveal that NiZr2 has a positive thermal expansion, while the other compounds exhibit uniaxial negative thermal expansion along the c-axis contraction. The study suggests that the c-axis thermal expansion can be controlled by manipulating the c/a ratio through Tr-site substitution, providing a design principle for achieving negative thermal expansion of the c-axis and potentially zero thermal expansion in a single compound in TrZr2 compounds.

Published: February 2023

Background and Objectives - Diabetes and hypothyroidism are common endocrine diseases that impact health and mortality. Glycaemic status
affects thyroid hormone levels immensely. There is a paucity of studies from India that have investigated the prevalence of subclinical
hypothyroidism in patients with type 2 diabetes mellitus. In this study, we determined the prevalence of subclinical hypothyroidism in type two
diabetes mellitus patients. Renal function is affected both by thyroid hormones and glycemic status, hence we have analysed renal function in the
study subjects. Our study was conducted in the Department of Medicine of North D Methods - elhi Medical College & Hindu Rao Hospital, Delhi.
A total of 150 patients with type 2 diabetes were screened for thyroid dysfunction, a group of 126 patients with normal thyroid function, 13 patients
with subclinical hypothyroidism, and 11 patients with overt hypothyroidism were subjected to the renal function tests. 126 (84%) Results –
patients out of 150 were classied as euthyroid. 11(7.3%) and 13 (8.7%) patients had overt hypothyroidism and subclinical hypothyroidism
respectively. Serum creatinine value was within the normal range in 90.4% of the euthyroid diabetics. However, only 69.2% of patients with SCHT
had normal serum creatinine levels. There was a signicant difference between the eGFR in euthyroid and the SCHT group, with mean eGFR in the
euthyroid group being 78.26± 17.9mL/min/1.73m2 and 57.92± 27.4mL/min/1.73m2 in the SCHT group. The i Conclusion - ncidence of
subclinical hypothyroidism in patients with type 2 diabetes mellitus was signicantly increased with increasing age and in female patients. Type 2

Finerenone: a new approach to the treatment of chronic kidney disease in patients with type 2 diabetes
Authors: D’Errico, M. M.
Published: February 2023

Chronic kidney disease (CKD) represents one of the leading causes of morbidity and mortality worldwide, being diabetes its first cause. Besides the strict management of risk factors (i.e. hyperglycemia, hypertension and dyslipidemia), several pharmacological strategies aiming at reducing the progression of CKD, including ACE-inhibitors, have been proposed. Finerenone is the first non-steroidal selective mineralocorticoid receptor antagonist (ns-MRA) drug developed for the treatment of diabetic kidney disease (DKD) in patients with type 2 diabetes (T2D). Its properties include a high selectivity for MRs with a lower incidence of side effects such as gynecomastia and hyperkalemia with respect to older steroidal MRAs. In addition, a significant reduction of fibrosis, inflammation and hypertrophy both on myocardium and kidney has been observed. At present, several studies demonstrating the efficacy and safety of finerenone on clinical outcomes have been published. In the phase III studies, FIDELIO-DKD and FIGARO-DKD, finerenone significantly reduced the combined primary endpoints (progression of chronic kidney disease, renal failure or renal death for renal outcomes, and cardiovascular mortality, non-fatal myocardial infarction, non-fatal stroke or hospitalisation for heart failure for cardiovascular outcomes) when compared to placebo and added to the standard of care. A pooled-analysis (FIDELITY) performed on a prespecified pool of patients derived from the combination of the previous two studies confirmed the ability of finerenone to significantly reduce both the incidence or progression of DKD and cardiovascular events. A higher incidence of hyperkalemia in patients treated with finerenone compared to placebo was confirmed. However, the incidence of adverse events with clinical impact was low, and only 1,7% of finerenone-treated patients versus 0,6% of placebo-treated patients discontinued treatment during a 3-year follow-up. Finerenone broadly demonstrates an effective renal and cardiovascular protective capacity in patients with T2D and DKD in the presence of good safety in its use.

Published: February 2023

The Gender medicine strategic group of AMD promoted an online survey in summer 2022 in order to know the size of violence in the workplace in the diabetologist community and this phenomenon can be correlated to lacks of Risk Assessment in the workplaces. We asked 20 questions about any experiences of violence suffered in the workplaces. The partecipants were 137, mainly women (71,5%). The most representative age range is 45 - 60 years (43,1%). About half of the respondents (46%) regardless of genders had been subjected of some form of violence during the exercise of profession, more often in surgeries daily, mainly by male patients, while women are mainly exposed to the risk of both verbal and physical violence. Among the subjects who have suffered experience of violence, in 74,6% of cases the phenomenon was repeated. Probably this data cannot exclude that some health workers due to personal characteristics or context are more often the target of this phenomenon, especially since health services and or companies do not provide readily available and effective strategies for rescue and or escape. It is a low propensity to report the violence and the lack of standardized procedures for the report management. Establishing a violence prevention program must the business goal aimed at guaranteeing safety in the workplace. KEY WORDS violence in the workplace; diabetology; age; gender; violence prevention program.
How Teacher Training on Analytic Philosophy Can Help Schools in Developing a Decommodified Interpretation of Coding Activities
Authors: Di Stasio Margherita , Donati Beatrice , Bianchini Matteo
Published: February 2023

The term “coding” is used to label a wide range of learning activities directly or indirectly related to the design and implementation of algorithmic procedures. These activities are now widespread in all levels of schools and are performed in very different pedagogical frameworks. Our hypothesis is that teachers look at coding from a perspective strongly influenced by their background. In particular, we deem that a logical and philosophical training may foster a de-commodified vision of coding and computational thinking. We have therefore decided to design and experiment a teacher training path that provides participants with some basics of logic and analytical philosophy. We analysed if and how this kind of training influences classroom coding activity. In the first part of this contribution (Sections 1 to 3) we introduce the theoretical framework underlying our hypothesis as well as the training and educational activities proposed to teachers. In the second part (Sections 4 to 7), we present the results of this path by means of a comparative case study focusing on the coding practices implemented in the experiences.

Published: February 2023

As a material forming method, cold forging is preferred due to the reasons like absence of a heating step and high surface quality. Recently, the finite element method (FEM) has received growing attention for controlling and predicting final material properties for cold forging applications. FEM combines microstructure evolution models with failure criteria, thus providing solutions to complicated problems in the modern cold forging industry. The fastener industry extensively utilizes cold forging, in which manganese and boron-containing steels like 27MnB4 can be formed to obtain high mechanical properties. The current study investigates the effect of two different heat treatments, namely softening and spheroidizing annealing, on the formability of 27MnB4 bolts. Softwares such as Thermo-Calc 2022a and Forge NxT 3.2 were used to predict the microstructure of the wire rod and evaluate the cold forming process of the same rod under two different heat treatment conditions. Therefore, the current study also provides a relationship between microstructural features and the cold formability of 27MnB4 steel. The microstructure of 27MnB4 is predicted by CCT diagrams. The predicted microstructure corresponds to the microstructure of 27MnB4 samples taken from the production line. In addition, temperature, von Mises stress, and equivalent strain distributions for 27MnB4 steel in the hot rolled state were calculated higher than in annealed states due to the differences in the microstructure. These results demonstrate that computational material engineering methods and simulation techniques could be practical tools for cold forming processes.

At increasing energy levels, the HVL value reached approximately 10 cm, while the MFP value reached approximately 17 cm. In the second part of the study, the reactor core geometry was modeled with the MCNP code and then the relative power distribution values were determined. COBRA code input was prepared with the determined relative power distribution values and thermal analyzes were made. These analyzes were performed for three different nanoparticle ratios. As a result of the analysis, the temperature value at the end of the channel was 613 K when only water was used as a coolant, while the temperature value at the end of the channel was 611.19 K when 0.03% nanoparticles were used. Although the coolant temperature increased with the nanoparticle ratio, it was observed that the temperature decreased when only water was used.
COMPARATIVE PERFORMANCE ANALYSIS OF A FEED-FORWARD NEURAL NETWORK-BASED MPPT FOR RAPIDLY CHANGING CLIMATIC CONDITIONS
Authors: ALHAJ OMAR Fuad
Published: February 2023

Rapid and abrupt changes in climatic conditions present a challenge to classical MPPT techniques as they drift from the MPP, resulting in loss of power. This paper presents a new MPPT technique based on a feed-forward artificial neural network (FFANN) and a direct control technique. In the proposed approach, FFAAN estimates the optimum value of the PV output voltage V_MPP, while the direct control technique achieves an optimal adjustment of the duty cycle making the operating point at MPP. To evaluate the performance of the proposed technique, the accurate electrical model of the system parts was built and simulated in MATLAB/Simulink environment. The simulation results are collected under rapidly changing climatic conditions. Simulation results show that the proposed MPPT technique achieves higher performance in terms of tracking efficiency and convergence speed compared to both the IC-based MPPT and FL-based MPPT systems. The results show that the proposed technique accurately estimates V_MPP, achieving a tracking efficiency of 99.9%, while the tracking efficiency is 94% when using FL-based MPPT and 91.5% when using IC-based MPPT. This demonstrates that the proposed technique exhibits superior performance under rapidly changing climatic conditions and increases energy production efficiency compared to classical techniques.

Polyamides are preferred polymer materials for manufacturing industrial products due to their lightness, resistance to corrosion, ease of processing, and recyclability. In this study, the machinability properties of Polyamide 6 (PA6) polymer composite plates reinforced with chopped carbon fiber (CF) and multi-walled carbon nanotube (MWCNT) in different proportions were investigated by the drilling method using different cutting tools and cutting parameters. The experiments were carried out according to the L16 orthogonal array. Drilling experiments were carried out in a dry environment. The deformations occurring on the inlet and outlet surfaces of the drilled samples were calculated, and the surface roughness (Ra) of the hole walls was measured. According to the results obtained, the particle addition made to the PA6 polymer reduced the Ra. It has been observed that high cutting speed and low feed rate are ideal parameters to achieve low Ra and low inlet-outlet deformations.

For the training and testing steps of ANFIS, wind speed, air density, and output power of the wind turbine are used as input-output parameters. As a result of the simulations and training, the percent relative error value in the widest range where the prediction value deviates from the true value is 11.86%. This value was higher than expected due to the scarcity of the data used in the ANFIS training (144) and the repetitive values in the output power. Similarly, the lowest efficiency value is 89.4%. Despite all this, it has been observed that ANFIS gives good results if the data used in the testing process is within the scope of the data used in the training. Moreover, the developed model when supported with 32-bit hardware can make real-time power estimation for a real wind turbine. The main motivation for this study; is develop a model that can predict the output power for the Vestas V44-600 model based on wind speed and air density data. In addition, it is to produce the Fuzzy Interface System (FIS) file that enables the developed model to run on embedded systems.

Rolling Gas Numbers to Keep Sun Rising & Shining in the East
Authors: Zheng Jimmy
Published: February 2023

What we do know from the numbers is that gas in the ground, particularly from Queensland, is not a major issue. On the flipside, the ongoing decline of conventional gas resources in Victoria is well known. Nonetheless, subject to timely capital investment, Victoria’s decline can be stabilized, particularly as we have actually seen year-to-date growth in Victorian gas supply compared to 2021 of roughly 13%. This reflects the efforts of operators to reinvest in the Otway Basin and the impact of ExxonMobil’s recent West Barracouta development.
