Lytic polysaccharide monooxygenases: enzymes for controlled and site-specific Fenton-like chemistry
Authors: Bissaro Bastien , Eijsink Vincent G.H.
Published: April 2023

The discovery of oxidative cleavage of glycosidic bonds by enzymes currently known as lytic polysaccharide monooxygenases (LPMOs) has profoundly changed our current understanding of enzymatic processes underlying the conversion of polysaccharides in the biosphere. LPMOs are truly unique enzymes, harboring a single copper atom in a solvent-exposed active site, allowing them to oxidize C-H bonds at the C1 and/or C4 carbon of glycosidic linkages found in recalcitrant, often crystalline polysaccharides such as cellulose and chitin. To catalyze this challenging reaction, LPMOs harness and control a powerful oxidative reaction that involves Fenton-like chemistry. In this essay, we first draw a brief portrait of the LPMO field, notably explaining the shift from the monooxygenase paradigm (i.e., using O2 as cosubstrate) to that of a peroxygenase (i.e., using H2O2). Then, we briefly review current understanding of how LPMOs generate and control a hydroxyl radical (HO•) generated through Cu(I)-catalyzed H2O2 homolysis, and how this radical is used to create the proposed Cu(II)-oxyl species, abstracting hydrogen atom of the C-H bond. We also point at the complexity of analyzing redox reactions involving reactive oxygen species and address potential deficiencies in the interpretation of existing LPMO data. Being the first copper enzymes shown to enable site-specific Fenton-like chemistry, and maybe not the only ones, LPMOs may serve as a blueprint for future research on monocopper peroxygenases.
A special issue of Essays in Biochemistry on current advances about CAZymes and their impact and key role in human health and environment
Authors: Czjzek Mirjam , Ficko-Blean Elizabeth , Berrin Jean-Guy
Published: April 2023

Carbohydrate active enzymes (CAZymes) and their biochemical characterization have been the subject of extensive research over the past ten years due to their importance to carbohydrate metabolism in different biological contexts. For instance, the understanding that ‘polysaccharide utilizing loci’ (PUL) systems hosted by specific ‘carbohydrate degraders’ in the intestinal microbiota play key roles in health and disease, such as Crohn’s disease, ulcerative colitis or colorectal cancer to name the most well-characterized, has led to an outstanding effort in trying to decipher the molecular mechanisms by which these processes are organized and regulated.

The past 10 years has also seen the expansion of CAZymes with auxiliary activities, such as lytic polysaccharide monooxygenases (LPMOs) or even sulfatases, and interest has grown in general about the enzymes needed to remove the numerous decorations and modifications of complex biomass, such as carbohydrate esterases (CE). Today, the characterization of these ‘modifying’ enzymes allows us to tackle a much more complex biomass, which presents sulfations, methylations, acetylations or interconnections with lignin.

This special issue about CAZyme biochemistry covers all these aspects, ranging from implications in disease to environmental and biotechnological impact, with a varied collection of twenty-four review articles providing current biochemical, structural and mechanistic insights into their respective topics.
Modeling Responses to Auditory Feedback Perturbations in Adults, Children, and Children With Complex Speech Sound Disorders: Evidence for Impaired Auditory Self-Monitoring?
Authors: Terband Hayo , van Brenk Frits
Published: April 2023

Purpose:

Previous studies have found that typically developing (TD) children were able to compensate and adapt to auditory feedback perturbations to a similar or larger degree compared to young adults, while children with speech sound disorder (SSD) were found to produce predominantly following responses. However, large individual differences lie underneath the group-level results. This study investigates possible mechanisms in responses to formant shifts by modeling parameters of feedback and feedforward control of speech production based on behavioral data.

Method:

SimpleDIVA was used to model an existing dataset of compensation/adaptation behavior to auditory feedback perturbations collected from three groups of Dutch speakers: 50 young adults, twenty-three 4- to 8-year-old children with TD speech, and seven 4- to 8-year-old children with SSD. Between-groups and individual within-group differences in model outcome measures representing auditory and somatosensory feedback control gain and feedforward learning rate were assessed.

Results:

Notable between-groups and within-group variation was found for all outcome measures. Data modeled for individual speakers yielded model fits with varying reliability. Auditory feedback control gain was negative in children with SSD and positive in both other groups. Somatosensory feedback control gain was negative for both groups of children and marginally negative for adults. Feedforward learning rate measures were highest in the children with TD speech followed by children with SSD, compared to adults.

Conclusions:

The SimpleDIVA model was able to account for responses to the perturbation of auditory feedback other than corrective, as negative auditory feedback control gains were associated with following responses to vowel shifts. These preliminary findings are suggestive of impaired auditory self-monitoring in children with complex SSD. Possible mechanisms underlying the nature of following responses are discussed.

Due to migration, terror‐threats and the viral pandemic, various EU member states have re‐established internal border control or even closed their borders. European Association for Biometrics (EAB), a non‐profit organisation, solicited the views of its members on ways which biometric technologies and services may be used to help with re‐establishing open borders within the Schengen area while at the same time mitigating any adverse effects. From the responses received, this position paper was composed to identify ideas to re‐establish free travel between the member states in the Schengen area. The paper covers the contending needs for security, open borders and fundamental rights as well as legal constraints that any technological solution must consider. A range of specific technologies for direct biometric recognition alongside complementary measures are outlined. The interrelated issues of ethical and societal considerations are also highlighted. Provided a holistic approach is adopted, it may be possible to reach a more optimal trade‐off with regards to open borders while maintaining a high‐level of security and protection of fundamental rights. European Association for Biometrics and its members can play an important role in fostering a shared understanding of security and mobility challenges and their solutions.
A novel energy efficient two‐dimensional pilot muting mechanism for non‐stationary channel fading environment
Authors: Sun Yanzan , Tan Hongchang , Yu Tao , Zhang Shunqing , Chen Xiaojing
Published: April 2023

To support communication channels with non‐stationary properties, the pilots are usually configured for the channel worst case in order to ensure the accuracy of tracking the channel, which inevitably causes a waste of resources. To solve this issue, first, a flexible two‐dimensional pilot muting mechanism is proposed by exploiting the time and frequency diversity of the pilot sequence of the resource grid for non‐stationary channel fading environment. Then a super‐resolution based non‐stationary channel recovery scheme for data channel recovery is further proposed for two‐dimensional pilot muting, and the energy efficiency of a resource block is also maximized. Numerical results show that the proposed mechanism can bring about as much as 8 dB performance gain in system energy efficiency.
Dynamic traffic signal control using mean field multi‐agent reinforcement learning in large scale road‐networks
Authors: Hu Tianfeng , Hu Zhiqun , Lu Zhaoming , Wen Xiangming
Published: April 2023

Multi‐agent reinforcement learning has played an increasingly important role in intelligent traffic signal control due to its self‐learning ability. However, existing algorithms only focus on signal timing mechanism design while ignoring the exponential growth of the joint action dimension as the number of intersections increases, which will ultimately face the learning difficulty. In this paper, traditional traffic methods are introduced into MARL to flexibly determine the phase and duration of each intersection. The proposed MARL algorithm based on mean field theory has the ability to convert a large number of agents to approximately binary interaction, which can effectively reduce the dimension of joint action space in multi‐agent environment and learn in a robust process. Besides, to improve the performance of traditional traffic methods, the recurrent neural network (RNN) and an improved Webster's formula with revised parameters are combined to dynamically determine the phase duration according to the historical volume of traffic flow. The simulation results indicate that the proposed algorithm shows superior scalability compared to baseline methods and has great potential to be applied in the large scale road‐networks scenario.
High performance bit‐activation code index modulation method
Authors: Liu Fang , Zheng Yuanfang , Feng Yongxin
Published: April 2023

With the increasing demand of applications for the spread spectrum technique, especially the demand for data transmission rates and spectral efficiency, the advantages of the traditional direct sequence spread spectrum (DSSS) system are limited. Therefore, multi‐ary spread spectrum (M‐ary) technology, parallel combinatory spread spectrum (PCSS) technology, and code index modulation (CIM) technology have been proposed. Although these three new technologies can improve the data rate, they all face the problem of the large consumption of pseudo‐code resources. In order to solve the problem of pseudo‐code resources, a bit‐activation code index modulation (BA‐CIM) method is proposed. At the transmitter, considering the good correlation among multiple pseudo‐codes, the corresponding pseudo‐code activation principle is established, and the corresponding spreading pseudo‐code is activated by using the status of each bit of the index data according to the pseudo‐code activation principle. Then, multicode superposition processing is carried out to spread the modulation data. At the receiver, the corresponding activation pseudo‐code is obtained using the maximum peak‐to‐average ratio (MPAR) and secondary peak‐to‐average ratio (SPAR) judgement mechanisms to decode the multibit index data. Compared with existing methods, the proposed BA‐CIM method can not only achieve a better bit error rate performance but also use the least pseudo‐code resources. Moreover, BA‐CIM has the best comprehensive performance improvement and is far superior to other methods. This research can provide technical support for the application of efficient spread spectrum communication.

Published: April 2023

Optimization of the cotton breeding process at the present stage is the main condition for the success of practical breeding. The need for continuous change and improvement of varieties, as well as a reduction in the timing of their breeding, requires a revision of the arsenal of breeding methods and many theoretical attitudes from the point of view of the ideas of modern genetics. The ideas of statistical genetics are especially effective for the development of the theory and methods of selection, as well as its central link - the theory of selection and selection of parental pairs. In practical terms, they make it possible to develop the most accurate criteria for the selection, selection and evaluation of breeding material, and this is the main content of optimization of the breeding process. Even in the strictest self-pollinators, although rarely, the plants are re-pollinated or, in any case, are capable of re-pollinating. Consequently, plants can exchange genetic material, transmit the emerging hereditary changes to each other, and it can be considered as a potential population. This article presents the results of studies to study the possibility of using the dominance coefficient when assessing cotton families. It was shown that phenotypically homogeneous families when crossing show different degrees of manifestation of the studied traits in F1 hybrids.

This article analyzes the strategies that serve to facilitate the work of the translator in the process of simultaneous translation. Most of the simultaneous translation researchers understand the strategy as a necessary skill or certain skills of the conference interpreter in processing the message when translating from the source language to the target language. In simultaneous translation, the interpreter uses several strategies at the same time. The decision is usually made on a case-by-case basis. It was also suggested that linguistic and extralinguistic factors influence this situation.

Creditors whose claims are secured by the debtor’s property have a privileged position in the insolvency proceedings. The legal status of depositors and the manner in which their claims are met are the subject of close research. However, the problem of bail is little studied in Russian doctrine. The purpose of the present study is to formulate, on the basis of regulation and doctrinal thinking in Germany, where the right to a bond of arrest has been successfully applied, a framework for the exercise of the right of a bond of arrest in insolvency proceedings (bankruptcy) for Russian legislation. The main methods of the study are: Comparative law, which allows the study of the theoretical provisions of the right to bail and the proposal of appropriate legislative designs; as well as the historicallegal method combined with the systematic method of analysis of the problem under investigation. Synthesis, interpretation and teleological methods are also used. Since the study of property rights in Germany has had a significant impact on the Russian doctrine, the German experience of the legal regulation of a creditor whose claims are secured by the seizure of property has been used in the analysis of the problems of a bond of arrest. The legal nature of the right to bail, which is the subject of debate in the doctrine of Germany and Russia, has been analysed. It has been concluded that the right to an arrest bond is a special right of bail, together with a contractual and legal bond. It is substantiated that there is a gap in Russian law regarding the legal position of a creditor in insolvency proceedings (bankruptcy) in the event of securing his claims by seizure of the debtor’s property. The preferential right of tax authorities to obtain satisfaction in insolvency proceedings in the attachment of taxpayer property, qualified as a legal security, introduced in Russian tax legislation, It is considered to be a breach of the balance between public and private interests. It is justified that the right to a bond of arrest is subject to the law of procedural law and proposals have been made to regulate the legal position of creditors entitled to a bond of arrest in insolvency proceedings (bankruptcy).

The article studies the operation of building frame structures with outrigger floors, taking into account seismic effects. The object of the study is a monolithic reinforced concrete frame of the building. The studies were carried out using the modern Lira SAPR software package, which implements the finite element method. Dynamic calculations were performed for several models with different design solutions for outrigger systems and their location. The study of the effectiveness of the decisions made was carried out based on the results of the spectrum of frequencies and periods of natural oscillations. Based on the results of dynamic calculations, two constructive solutions were chosen with higher frequencies and shorter oscillation periods compared to the original model. A study was made of the effect of outrigger floors on the stress-strain state of the building frame. Based on the results of the calculation, conclusions are drawn and recommendations are given for the design of earthquake-resistant buildings.

Published: April 2023

The paper is devoted to the identification of key factors which influence commercial banks’ economic profit. The data of 50 Russian banks from 2011 to 2020 are analysed. Among the determinants of banks’ profitability, the factors of operational, financial, and macroeconomic profile are investigated with the use the system generalized method of moments (GMM). The novelty of the study concerns the expansion of the existing list of determinants which influence the banks’ profitability with additional factors, such as the level of service, the type of business model, insolvency risk. Also, the paper implies the use of spread of Economic Value Added as a measure of banks’ profitability, which relates to rather new and less studied economic approach in the existing literature compared with traditional ROA and ROE indicators. It is important to establish that there are no actual studies of Russian banking sector in the existing literature. The obtained results of the current study of Russian commercial banks can be used for both internal and external purposes.

Published: April 2023

The article discusses issues related to children's health care in the Kazakh SSR during World War II. Based on archival data the authors of the article concluded that the increase in child mortality in the early years of the war was due to the high incidence of infectious diseases such as whooping cough, diphtheria, dysentery, pneumonia, scarlet fever, measles, and others. The reasons were the shortage of the necessary number of medical institutions, their insufficient equipment and absence of qualified medical staff, untimely detection of diseases and late hospitalization, lack of quarantine boxes and certain percentage of unvaccinated children. Among other reasons there are low living standards of the population, poor sanitary conditions in some children's institutions, and nutritional problems of children. All this led to increased morbidity and mortality of children in the early period of the war.

The work is devoted to the development of technology for enriching artemia with biologically active substances. The development of technology for enriching artemia with biologically active substances is important as an opportunity to obtain starter feeds for aquaculture with the desired properties. High content of high-grade protein, vitamins, amino acids, fatty acids, biogenic elements is of great importance. During artificial cultivation of artemia in a closed cycle in the conditions of aquaculture, there is a problem of sufficient accumulation of substances in its body that provide high nutritional and biological value. To solve this problem, we have developed a technology for enriching artemia with biologically active substances at the nauplium stage. The enrichment of artemia with vitamins, amino acids, probiotics, adaptogens, essential lipids allows us to create a new generation of bio-feeds containing a living symbiotic microbiota and ingredients capable of forming balanced complex of functional nutrition for fish. The aim of the study was to evaluate the biological and energy value, the content of proteins, fats, carbohydrates, moisture, ash, micro- and macroelements, heavy metals in artemia at different stages of ontogenesis against the background of its enrichment with a complex of biologically active substances. Intact and enriched cysts, intact and enriched decapsulated artemia eggs, enriched artemia nauplii were analyzed. It was found that against the background of enrichment with biologically active substances, the indicators of metabolic energy increased, the mass fraction of crude protein, the mass fraction of fat and the content of minerals and biogenic elements increased.
