Published: January 2022

Fatty acid desaturases (FADs) are a class of enzymes that mediate desaturation of fatty acids by introducing double bonds. They play an important role in modulating membrane fluidity in response to various abiotic stresses. However, a comprehensive analysis of FAD3 in drought and salinity stress tolerance in soybean is lacking. We used Bean Pod Mottle Virus (BPMV)-based vector for achieving rapid and efficient overexpression as well as silencing of Omega-3 Fatty Acid Desaturase gene from Glycine max (GmFAD3) to assess the functional role of FAD3 in abiotic stress responses in soybean. Higher levels of recombinant BPMV-GmFAD3A transcripts were detected in overexpressing soybean plants. Overexpression of GmFAD3A in soybean resulted in increased levels of jasmonic acid and higher expression of GmWRKY54 as compared to mock-inoculated, vector-infected and FAD3-silenced soybean plants under drought and salinity stress conditions. FAD3A overexpressing plants showed higher levels of chlorophyll content, efficient photosystem-II, relative water content, transpiration rate, stomatal conductance, proline content and also cooler canopy under drought and salinity stress conditions as compared to mock-inoculated, vector-infected and FAD3-silenced soybean plants. Results from the current study revealed that GmFAD3A overexpressing soybean plants exhibited tolerance to drought and salinity stresses. However, soybean plants silenced for GmFAD3 were vulnerable to drought and salinity stresses.

Background: Ticks are important parasites that cause more diseases than most other animal parasites. Haemaphysalis longicornis is used as an experimental animal model for the study of three-host ticks due to its special life cycle and easy maintenance in the laboratory and in its reproduction. The life cycle of H. longicornis goes through a tightly regulated life cycle to adapt to the changing host and environment, and these stages of transition are also accompanied by proteome changes in the body. Methods: In this study, the aim was to use the isobaric tags for relative and absolute quantification (iTRAQ) technique to systematically describe and analyze the dynamic expression of protein and the molecular basis of the proteome of H. longicornis in seven differential developmental stages (eggs, unfed larvae, fed larvae, unfed nymphs, fed nymphs unfed adults, and fed adults). Results: A total of 2,059 proteins were identified, and their expression profiles were classified at different developmental stages. In addition, it was found that tissue and organ development-related proteins and metabolism-related proteins showed that they were involved in different physiological processes throughout the life cycle through the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis of the differentially expressed proteins (DEPs). More importantly, we found that the upregulated proteins of fed adult ticks were mainly related to yolk absorption, degradation, and ovarian development-related proteins. The abundance of the cuticle proteins in the unfed stages were significantly higher compared with those of the fed ticks in the previous stages. Conclusions: In short, the protein spectrum changes identified in this study provide a reference proteome for future studies of tick functional proteins and provide candidate targets for elucidating tick development and developing new tick control strategies.

Background: The pathological features of severe cardiac injury induced by COVID-19 and relevant clinical features is unknown. This post-mortem study intended to determine the pathological findings of hearts from critically ill COVID-19 cases and explore the association of pathological changes and clinical characteristics.Methods: This autopsy cohort study, including hearts from 26 deceased COVID-19 patients admitted in intensive care unit, was conducted at four sites in Wuhan, China. Pathological changes were evaluated using hematoxylin and eosin, and immunohistochemical staining. Cases were divided into neutrophil-infiltration group and no-neutrophil group according to histopathological identification of neutrophilic infiltrates or not. Results: Among 26 cases, four cases had active myocarditis with histopathological examination. All cases with myocarditis accompanied with extensive neutrophil infiltration, while cases without myocarditis did not. Detection rates of interleukin-6 and tumor necrosis factor-α in neutrophil-infiltration group were significantly higher compared to no-neutrophil group. At admission, patients with neutrophil infiltration in myocardium had significantly higher baseline values of aspartate aminotransferase, D dimer and high-sensitivity C reactive protein compared to other 22 patients (P<0.05 for all). During hospitalization, patients with neutrophil infiltration had a significantly higher maximum of creatine kinase (CK)-MB than patients without neutrophil infiltration. Conclusions: In hearts from deceased patients with severe COVID-19, active myocarditis was commonly infiltrated with neutrophils. Cases with neutrophil-infiltrated myocarditis had severe abnormal laboratory tests involving multiple organs at admission, and a high peak value of CK-MB during hospitalization. Role of neutrophil on severe heart injury and even systemic condition in COVID-19 should be emphasized.

Published: January 2022

Aspect-level sentiment classification aims to integrating the context to predict the sentiment polarity of aspect-specific in a text, which has been quite useful and popular, e.g. opinion survey and products’ recommending in e-commerce. Many recent studies exploit a Long Short-Term Memory (LSTM) networks to perform aspect-level sentiment classification, but the limitation of long-term dependencies is not solved well, so that the semantic correlations between each two words of the text are ignored. In addition, traditional classification model adopts SoftMax function based on probability statistics as classifier, but ignores the words’ features in the semantic space. Support Vector Machine (SVM) can fully use the information of characteristics and it is appropriate to make classification in the high dimension space, however which just considers the maximum distance between different classes and ignores the similarities between different features of the same classes. To address these defects, we propose the two-stages novel architecture named Self Attention Networks and Adaptive SVM (SAN-ASVM) for aspect-level sentiment classification. In the first-stage, in order to overcome the long-term dependencies, Multi-Heads Self Attention (MHSA) mechanism is applied to extract the semantic relationships between each two words, furthermore 1-hop attention mechanism is designed to pay more attention on some important words related to aspect-specific. In the second-stage, ASVM is designed to substitute the SoftMax function to perform sentiment classification, which can effectively make multi-classifications in high dimensional space. Extensive experiments on SemEval2014, SemEval2016 and Twitter datasets are conducted, compared experiments prove that SAN-ASVM model can obtains better performance.

Published: January 2022

Barium-calcium phosphoaluminate ((C,B)8A6P) mineral was synthesized by introducing Ba2+ into the lattice of calcium phosphoaluminate (C8A6P) mineral and it owned the better hydration activity than C8A6P. In this study, the formation kinetics and mechanism of (C,B)8A6P mineral was firstly systematically explored. The experimental results indicated that calcination temperature had a significant effect on the formation of (C,B)8A6P mineral. The conversion rate of (C,B)8A6P mineral was less than 0.5 and reaction rate was less than 9.4 × 10-7 with the holding time of 8 h at 1500-1530 °C. Nevertheless, the conversion rate and reaction rate reached 0.8 and 9.4 × 10-7, respectively, with the holding time of only 2 h when the calcination temperature ranged from 1540 °C to 1560 °C. In addition, the Jander equation was feasible for the formation of (C,B)8A6P with activation energy of 1310 kJ ∙ mol-1 at 1500-1530 °C, while the Ginstling equation was feasible for use with activation energy of 324 kJ ∙ mol-1 when the calcination temperature ranged from 1540 to 1560 °C.

Authors: Raghava Neha , Perkins Matthew , Thomas Graham
Published: January 2022

In light of the novel coronavirus and transmission in schools, increased scrutiny has been placed on airborne viral and particulate contamination, and efforts to mitigate this have been suggested, including the use of air purification. The importance of this is increased given the relationship between increased airborne particulates and increased coronavirus transmission, as well as the significance of removing particulates in the size range of bacteria and viruses from the air. Ambient levels of pm2.5 and pm1 in the absence of purification were recorded in two classrooms of similar size using medical grade data loggers, which then measured the change in these levels with use MedicAir air purifiers. It was found that baseline levels at times doubled the WHO limits for safe IAQ- MedicAir units were able to rapidly reduce levels of particulates to significantly below guidelines. We propose that the use of these units is an effective and rapid solution for the mitigation of coronavirus transmission, as well as the improvement of IAQ in schools.

Published: January 2022

Increasing of demand for water, allocation of limited water resources, climatic variability, degradation of water in the environment and developing of policies for sustainable water use are issues of increasing concern in the Kontsa irrigation project. This study aimed at assessing the effects of selected irrigation methods on water demand and allocation among farmers in Kontsa irrigation project. The study employed both primary and secondary data. The primary data were collected by interviewing 80 farmers, key informant interviews and observation of the project area while secondary data were collected from different agencies of Ethiopia. For this study Water Evaluation and Planning (WEAP) model was used to model the current situation of irrigation water demand and also to create scenario for future irrigation water demand. The model was set up for a current account year in 2015 and last year of scenarios in 2040 based on the available data. Then the irrigation water demand of the project area was modeled while giving consideration for existing and planned developments in the area. The result from the current situation of irrigation water demand indicated that the demand was satisfied fully and the unmet demand under the base year (2015) was zero. Additionally, irrigation expansion scenario was created and the result of this scenario indicates the increment of irrigation water demand as compared to the base year and the reference scenario. The study also revealed that furrow irrigation and plastic buckets were the main irrigation techniques employed by farmers in the study area.

Published: January 2022

Background SARS-CoV-2, a novel corona virus, has caused clusters of fatal pneumonia worldwide. Immune compromised patients are among the high risk groups with poor prognosis of the disease. The presence of bacterial or fungal co-infections with SARS-CoV-2 is associated with increased mortality. Methods The electronic data of the liver and kidney recipients, hospitalized in COVID-19 intensive care unit in an 8-month period in 2020 were retrospectively assessed. The documented bacterial or fungal infections alongside with outcome and risk factors were recorded and analyzed by binary logistic regression model and multivariate analyses. Results Sixty-Six liver and kidney recipients were included this study. Twenty one percent of the patients had at least one episode of co-infection during their COVID-19 course. Bacterial and fungal co-infections contributed to a significantly higher mortality. Urine and sputum were the most common sites of pathogen isolation (45.45 % and 36.36%; respectively). The majority of infections were caused by vancomycin- resistant Enterococci (30%). Escherichia coli stood in the next position with 23.3%. Prior hospitalization and high does corticosteroid use were associated with co-infections (p=0<0.001 and p=0.02; respectively.)Conclusions Bacterial and fungal co-infections with COVID-19 are more prevalent in solid organ recipients compared to the general population. Prior hospitalizations and use of broad-spectrum antimicrobial agents lead to emergence of multi-drug resistant pathogens in this susceptible patient population. Early detection and treatment of co-infections as well as antibiotic stewardship is recommended in solid organ recipients.

Published: January 2022

Passiflora setacea DC (Passifloraceae) is considered an important species in the genetic breeding of passion fruit. However, its use is limited due to low seed germination. This paper aimed to study the effect of cytokinins 6-benzyladenine (BA) and thidiazuron (TDZ) on the in vitro morphogenesis of P. setacea using three explants: hypocotyl, nodal segment, and root segment. The explants were induced to morphogenesis in MS medium modified and with different concentrations of BA and TDZ. After 55 days, the percentage of calluses and shoots were evaluated, and anatomical characterization was performed. The three explants used in the in vitro morphogenesis of P. setacea showed callus and shoots formation, but in greater numbers in the nodal segments treated with BA. TDZ isolated affected equal to or less than BA on callus and shoots formation for the three explants. Direct and indirect organogenesis was observed in the three types of explants. From the results obtained for plant regeneration via in vitro morphogenesis of P. setacea, it is recommended to use a nodal segment in MSM medium and supplemented with 2.22 μmol L-1 of BA.
Optimal Autonomic Management of Service-Based Business Processes in the Cloud
Authors: Hadded Leila , Hamrouni Tarek
Published: January 2022

Cloud computing is an emerging paradigm that provides hardware, platform and software resources as services over the internet in a pay-as-you-go model. It is being increasingly used for hosting and executing service-based business processes. These business processes are exposed to dynamic evolution during their life-cycle due to the highly dynamic evolution of cloud environments. The main adopted technique is to couple cloud computing with autonomic management in order to build autonomic computing systems. Almost all the existing approaches on autonomic computing have been focused on modeling and implementing autonomic mechanisms without paying any attention to the optimization of the autonomic management cost. Therefore, in this paper, we propose a novel approach based on binary linear program for determining the optimal allocation of cloud resources to manage a service-based business process which guarantees the specific requirements of customers and minimizes the management monetary cost. Then, to validate our approach under realistic conditions and inputs, we extend the CloudSim simulator to model and simulate the behaviour of business processes and their management in a cloud environment. Experiments conducted on two real datasets highlight the effectiveness of our approach.

In this article, we introduce the variety of monadic MTL-algebras as MTL-algebras equipped with two monadic operators. After a study of the basic properties of this variety, we define and investigate monadic filters in monadic MTL-algebras. By using the notion of monadic filters, we prove the subdirect representation theorem of monadic MTL-algebras and characterize simple and subdirectly irreducible monadic MTL-algebras. Moreover, present monadic monoidal t-norm based logic (MMT L), a system of many valued logic capturing the tautologies of monadic MTL-algebras and prove a completeness theorem.AMS Classification: 08A72, 03G25, 03B50, 03C05.

Published: January 2022

It is essential to enhance life quality in patients with premature ventricular complexes (PVCs) with the use of radiofrequency ablation (RFA). The aim of the study was to assess symptom burden and life quality in patients with a low PVC burden following RFA. 31 individuals with a low PVC burden in whom RFA was indicated were included in the study. At baseline and after a year following RFA, the Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia (ASTA) scale was used for appraisal. A 24-hour Holter electrocardiogram was used to detect recurrent PVCs 12 months after the RFA intervention. ASTA scores related to symptom burden, including the near-syncope score, health-related quality of life (HRQOL) scales pertaining to physical and mental health, and consequently the total HRQOL score, were all diminished a year after RFA (p<0.001). The ASTA score for syncope symptoms was also reduced (p<0.05). A fall in mean PVC burden was seen from 8.0% to 0.8% (p<0.001). The long-term clinical endpoint in individuals with a low PVC burden following RFA is reported. Symptom load, life quality and ultimate PVC burden were all enhanced. Additional studies incorporating longer follow-up and monitoring periods, respectively, would be beneficial.
Dekolonisasi di Asia dan Pembacaan Alkitab yang Membebaskan dalam Pandangan Kwok Pui-Lan
Authors: Hasiholan Sonny Samuel
Published: January 2022

AbstractThe history of colonialization in Asia left traditions and perspectives that were often oppressive. Minority or weak groups, often become victims. When this oppression and injustice occurs, and the oppressed group feels it is normal, it will be passed on to the next generation. Oppressive traditions and worldviews also occur in Christianity and in Bible reading. This article explores how Feminist Theologian Kwok Pui Lan tries to decolonialize Bible reading through dialogue and imagination. Kwok Pui Lan, in particular, pays attention tothe injustice that is caused by problems of race and gender. With dialogue and imagination between Bible readers and listeners in their specific contexts the gospel message will reach everyone in their existence, and make them free human beings. In the end, the Bible and the good news it carries are not only read according to strong and powerful interests, but have a variety of voices that can greet anyone.

AbstrakSejarah kolonialisasi di Asia meninggalkan tradisi dan cara pandang yang tidak jarang menindas. Kelompok minoritas atau yang lemah, seringkali menjadi korbannya. Ketika penindasan dan ketidakadilan ini terjadi, dan kelompok yang tertindas merasa hal itu sebagai sebuah kewajaran maka akan bertahan dan diwariskan kepada generasi berikutnya. Tradisi dan cara pandang yang menindas juga terjadi dalam kekristenan dan pembacaan Alkitab. Artikel ini menelusuri bagaimana Kwok Pui Lan, seorang Teolog Feminis, mencoba melakukan dekolonialisasi terhadap pembacaan Alkitab diantaranya melalui dialog dan imajinasi. KwokPui Lan secara khusus memberikan perhatiannya kepada ketidakadilan yang dilatarbelakangi oleh persoalan ras dan gender. Dengan dialog dan imajinasi antara pembaca Alkitab dan pendengar dengan konteks mereka yang khas maka kabar baik dalam Alkitab akan sampai kepada setiap orang dalam keberadaan mereka, dan menjadikan mereka manusia yang merdeka. Pada akhirnya Alkitab dan kabar baik yang dibawanya tidak saja dibaca menurut kepentingan yang kuat dan berkuasa, melainkan memiliki keragaman suara yang dapatmenyapa siapa saja.

Published: January 2022

Digitalization, dematerialization of production and consumption, and structural shifts in the direction of service economy forming do promote to reduction of material use and sustainable development. The paper aims to investigate the role of digital, structural, economic, and social factors in sustainable development promotion in OECD countries. The paper uses the data on digital achievements, social and economic development of OECD member states from World Bank data sources for the period 2007–2018. The random-effects GLS regression model is used, and empirical regression models to estimate the influence of key factors related to digital transformation on GDP per capita and CO2 emissions per capita are constructed. The results of the regression analysis show that using the number of Internet users as an indicator for achievement in digitalization has a positive and statistically significant influence on GDP per capita due to lower transaction costs and higher share service economy. An increase in urbanization rates (as an indicator of capital concentrations and labor specialization) by one percent promotes a GDP per capita increase of 299 USD. Also, an increase in Gini coefficient by one percentage point correlates with decrease in GDP per capita on 196 USD and the reduction of CO2 per capita by 0.12 tones due to the structural shifts in aggregate demand. Still, improvements in digital transformations have no significant environmental effect in OECD members, while processes related to urbanization, income inequality, and share of industrial output are important drivers for CO2 per capita reduction.

Diabetes mellitus type 1 (T1DM) is an autoimmune disease characterized by a markedly
elevated cardiovascular (CV) risk due to premature atherosclerosis. Previous studies have shown
that intense glycemic control reduces the incidence of CV disease. Antiplatelet therapy is considered
to be a very important therapy for secondary prevention of recurrent atherothrombotic events
in patients with DM, while it may be considered for primary prevention in individuals with T1DM
with additional CV risk factors. The aim of the present review is to summarize existing literature
data regarding the thrombotic risk in T1DM patients and discuss current treatment strategies.
Acute to Subacute Spinal Cord Infarction Mimicking Acute Multiple Sclerosis:
Usefulness of Diffusion-weighted MRI for Diagnosis
Authors: Lee Kyoung Yeon , Khil Eun Kyung , Jo Sang Won , Jang Min Uk , Choi Jung-Ah , Lee Min-Sang
Published: January 2022

Background:

Spinal cord infarction (SCI) is difficult to diagnose because of its rarity,
unknown etiology, and unestablished diagnostic criteria. Additionally, the timeline of SCI has not
been studied in detail, as few studies using diffusion-weighted image (DWI) sequences of the spine
of a small target population have been previously conducted.

Case Study:

A 56-year-old male with underlying arrhythmia suddenly developed visual field defects
on the right side, pain in the left upper extremity, and a tingling sensation in the left hand.
Brain Magnetic resonance imaging (MRI) revealed acute to subacute stages of multifocal brain infarction.
On additional cervical spinal MRI, it showed atypical MRI findings of SCI, considered
late acute to early subacute phase, which were similar to those seen in the acute phase of multiple
sclerosis (MS). Additional DWI revealed restricted diffusion. From these findings, it could be inferred
that the patient’s SCI occurred at the same time as the multifocal brain infarctions caused by
atrial fibrillation.

Conclusion:

A DWI sequence of spine MRI could be helpful in the diagnosis of acute to subacute
phase SCI and in differentiating with acute MS.
Mekanisme Survival Selama Pandemi Covid-19: Belajar Dari Pengalaman Perempuan Single Mother di Perdesaaan Madura

Published: January 2022

The impact of the Covid-19 pandemic adds to the burden for single mothers. In addition to performing two functions at once, the pandemic forces them to survive difficult situations. This article describes the challenges facing single-mother as well as survival mechanisms during pandemics by phenomenological studies through direct observation and in-depth interviews conducted on single mothers in Ponteh Village. Data showed some of the challenges single-mother faced during the pandemic. First, there is an increase in double burden. One of the additional tasks for a single mother is the increasing burden of taking care of households needs due to their children’s schooling from home. Second, the decrease in income for household needs resulted from the government's mobility restriction policy. Third, the stereotyping of women (widows) that leads to social pressures. Survival mechanisms carried out by single mother during the pandemic are as follows. First, fostering optimism and taking care of each other. Second, using social relationships. Third, downsizing through reduced consumption and food substitutes, and fourth, diversifying and intensifying their jobs. This article therefore adds to the understanding that single mother women are no longer considered women who are unable to take care of their families when in fact they are able to overcome helplessness and difficult challenges.
Normal liver-to-heart transit time and shunt fraction after transplenic injection of 99MTC-pertechnetate in healthy cats
Authors: Vandermeulen E. , Peremans K. , Stock E. , Bosmans T. , Hesta M. , Saunders J.
Published: January 2022

Portosystemic shunts (PSS) are rare vascular anomalies in cats. Transsplenic portal scintigraphy (TSPS) can aid in diagnosing PSS in cats. Although the actual performance of the scan remains the same between species, it is questionable whether the generally accepted transit time of seven seconds for small dogs can be applied to cats, thereby influencing shunt fraction (SF) calculation. In this study, normal mean transit time and SF were determined in a population of cats without PSS following two methods established in canine medicine. For both, the mean ± SD transit time was calculated as 6.75 ± 1.58 seconds and 7.40 ± 1.64 seconds respectively, without significant difference between both methods. The results confirmed the validity of the generally used transit time of seven seconds for SF calculation in cats. The average normal SF (± SD) for the cats in this study was 0.73 % (±0.74; range 0.11-2.48%).

Furthermore, the purpose of this study is to evaluate the implementation of the learning process in vocational education programs, which includes an implementation of the teaching and learning process, the implementation of industrial training, lecturer skills in industrial supervision training, and encouraging entrepreneurship by lecturers to students. This study used a mixed-method design, and data were collected by questionnaires and depth-interview questions. The sample size is 218 graduates successfully collected using the total sampling technique. Data analysis used quantitative descriptive statistics (SPSS 23.0) and qualitative descriptive. Qualitative data support the quantitative results through interviews with five research informants. The results showed that graduates agreed that the teaching and learning process, the implementation of industrial training, lecturer skills in industrial supervision training, encouraging entrepreneurship by lecturers to students had gone well. In conclusion, the implementation of the vocational education program has been following the program's objectives. However, the results of the study showed that there are still weaknesses in the guidance from lecturers to students in the practice of opening a business and updating developments in related industries. Based on the results of this study, recommendations are made to focus on improving the process of implementing vocational education programs.

Floquet spectrum of charge carriers in a 2D crystal with initially displaced Dirac points has been derived. The phase and amplitude dependences of the energy gap induced by elliptically polarized and bichromatic high-frequency fields has been investigated. In contrast to graphene the linearly polarized electric field has been shown to be able to transform the initially semi-metallic state of Dirac crystal into the Floquet-insulator state. The conditions for such a transition are indicated, one of which is the mismatch between the orientation of the field polarization line and the direction of the crystallographic axes.

We researched the influence of damage accumulation on the Poisson's ratio measured by echo-pulse acoustic method during plastic deformation of 12Kh18N10T steel. On the basis of the obtained experimental data we calculated the partial contributions to the change in the Poisson's ratio of damage accumulation and separation of the strain induced martensite phase.
The characteristics of stable cracks forming near strain martensite particles at small degrees of plastic strain have been analyzed by computer simulation. The theoretical dependence of the change in the Poisson's ratio due to crack formation during plastic deformation has been constructed. A good agreement between the experimental data and theoretical calculations has been obtained.

The analysis of possible current distributions when passing current through a periodically modulated long Josephson contact located in an external magnetic field is carried out. An approach based on the analysis of continuous configuration modification proceeding in the direction of Gibbs potential reduction is used for the calculation. The case when the pinning parameter is less than the critical value is considered. It is shown that at any value of the external magnetic field, there is a critical value of the transport current, when exceeded, the situation ceases to be stationary, as a result of which energy passes into radiation and heat, i.e. currents cease to be persistent. The value of the critical current is determined by the value of the magnetic field at which the vortices begin to fill the entire length of the contact. With an increase in the external magnetic field, the critical value of the current decreases.

The results of a study of anodes obtained by carbonization of silicon monoxide by means of a reaction with solid-phase fluorocarbon CF0.8 are presented. Charge/discharge voltage profiles were studied at different currents depending on the composition and temperature of the synthesis of composites. The irreversible losses of the 1st cycle and the contribution to them of intrinsic losses due to the formation of lithium oxide and its silicates and losses associated with the formation of SEI are analyzed. A difference has been established in the behavior of anodes made of SiO carbonized by annealing with CF0.8 at T=800°C (SiO/C composite) and silicon monoxide annealed with CF0.8 at T>1000°C, at which disproportionation occurs simultaneously with the carbonization of SiO (d-SiO/C composite). The difference consisting in a higher discharge capacity, a higher Coulomb efficiency, and better rate capability of d-SiO/C is explained by a change in the composition of the SiOx matrix that occurs during the disproportionation process. The effect of the formation of d-SiO/C anodes by preliminary lithiation with a low current, after which the electrodes can be charged and discharged with much higher currents, has been discovered. The effect is explained by the amorphization of silicon crystallites and the increasing diffusion coefficient of lithium

Analytical relations for temperature response of the bolometer to periodic radiation pulses are obtained. It is theoretically shown and experimentally confirmed by the example of infrared bolometers that when detecting short radiation pulses, in contrast to the case of constant radiation, increasing the thermal conductivity of the bolometer and, accordingly, decreasing its thermal relaxation time, it is possible to significantly increase the response rate of the receiver, practically without reducing its sensitivity. The possibility of effective registration of pulsed terahertz radiation by microbolometers with a resistively coupled, thermally non-isolated antenna is considered. It is shown that such bolometers, which have increased thermal conductivity and, accordingly, reduced sensitivity to continuous-wave radiation, can be highly effective when detecting pulsed radiation with a duration shorter than the thermal relaxation time of the bolometer. On their basis, uncooled matrix detectors of pulsed terahertz radiation, characterized by a minimum detectable energy of less than 110-12 J and a frame rate of up to 1000 Hz, can be developed.

By methods of electron spectroscopy for chemical analysis and spectroscopy of characteristic losses of electron energy, the electronic structure of barium oxide crystallites doped with other chemical elements, including scandium from scandium-containing phases, was investigated. The physical and physicochemical conditions are formulated, the fulfillment of which allows to form the electronic structure of the scandate cathode with a high level of thermionic emission: the achievement of the minimum ratio of the surface volume concentration of oxygen vacancies and the maximum distance between the top of the valence band and the Fermi level.

Banana is one of the most important commodities for maintaining global food security. Primary metabolic processes during the ripening of banana greatly affect post‐harvest quality, particularly in starch metabolism. The beta‐ amylase (BAM) gene family is known as a group of genes that plays an important role in starch metabolism regulation. In this study, we focused on the characterization and comparative analysis of the BAM gene family in DH Pahang and Pisang Klutuk Wulung (PKW) varieties, these being the AA and BB genomes, respectively. The sequences of BAM gene family were retrieved from the database of Musa acuminata ’DH Pahang’ and Musa balbisiana ’PKW’ genome, then structural and functional characterization was performed, followed by identification of cis‐acting elements in the BAM promoter regions. The results showed that the BAM gene family structure was relatively conserved in both genomes, and a putative BAM11 gene was found, the function of which has not been studied in other plants. Cis‐acting element analysis showed that they were distinct in the copy number and types of elements that were responsive to various phytohormones. This study suggested that the BAM genes involved in ripening are spatiotemporally regulated. However, further functional genomic analysis is required to describe the specific role and regulation of BAM genes during ripening in banana.

The COVID-19 reality challenged the assumption underlying Articles31-31bisof the TRIPS agreement. It illustrated that the major obstacle to access of developing countries and LDCs to medicines and/or vaccines in cases of broad-scale, global pandemics is global production capacity and distribution priorities, namely: availability, rather than price. This article examines the future implications of this understanding.
El nuevo rol del Estado en el sector de las telecomunicaciones: el caso de la Red Compartida en México
Authors: Mariscal Judith
Published: January 2022

Desde hace una década, se ha observado un despliegue estatal de redes de próxima generación en el mercado de las telecomunicaciones. A primera vista, este giro en el papel del Estado parece incongruente en relación con la exitosa tendencia de mayor inversión y crecimiento liderada por el mercado que ha experimentado la industria durante los últimos veinte años. Una mirada más cercana revela una combinación de factores que llevaron a los gobiernos de todo el mundo a asumir un rol más activo en este mercado. Este artículo reflexiona sobre la participación del Estado en el auge de redes de infraestructura en el caso de México y de otros países de América Latina. Asimismo, se analizan comparativamente los cambios en el papel del Estado en las dos reformas de telecomunicaciones en México: 1990 y 2013. Se concluye que el cambio de rol del Estado no representa un retorno a un papel de proveedor de servicios que prevaleció durante la era de la posguerra, ya que la nueva ola coexiste con una promoción de la competencia de las empresas privadas en el mercado. El análisis destaca que ninguna de las reformas ha logrado resolver las grandes desigualdades en el acceso a las nuevas tecnologías de la información (tic) en México.
