Introduction

Chronic hip pain in middle-aged and older adults is common and disabling. Patient-centred care of chronic hip pain requires a comprehensive understanding of how people with chronic hip pain view their health problem and its care. This paper outlines a protocol to synthesise qualitative evidence of middle-aged and older adults" views, beliefs, expectations and preferences about their chronic hip pain and its care.

Methods and analysis

We will perform a qualitative evidence synthesis using a framework approach. We will conduct this study in accord with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement and the Enhancing Transparency in Reporting the synthesis of Qualitative research checklist. We will search MEDLINE, CINAHL, The Cochrane Central Register of Controlled Trials, EMBASE and PsycINFO using a comprehensive search strategy. A priori selection criteria include qualitative studies involving samples with a mean age over 45 and where 80% or more have chronic hip pain. Two or more reviewers will independently screen studies for eligibility, assess methodological strengths and limitations using the Critical Appraisal Skills Programme qualitative studies checklist, perform data extraction and synthesis and determine ratings of confidence in each review finding using the Grading of Recommendations Assessment, Development and Evaluation—Confidence in the Evidence from Reviews of Qualitative research approach. Data extraction and synthesis will be guided by the Common-Sense Model of Self-Regulation. All authors will contribute to interpreting, refining and finalising review findings. This protocol is registered on PROSPERO and reported according to the PRISMA Statement for Protocols (PRISMA-P) checklist.

Published: November 2021

Background

The COVID-19 pandemic led to changes in patterns of presentation to emergency departments. Child health professionals were concerned that this could contribute to the delayed diagnosis of life-threatening conditions, including childhood cancer (CC) and type 1 diabetes (T1DM). Our multicentre, UK-based service evaluation assessed diagnostic intervals and disease severity for these conditions.

Methods

We collected presentation route, timing and disease severity for children with newly diagnosed CC in three principal treatment centres and T1DM in four centres between 1 January and 31 July 2020 and the corresponding period in 2019. Total diagnostic interval (TDI), patient interval (PI), system interval (SI) and disease severity across different time periods were compared.

Results

For CCs and T1DM, the route to diagnosis and severity of illness at presentation were unchanged across all time periods. Diagnostic intervals for CCs during lockdown were comparable to that in 2019 (TDI 4.6, PI 1.1 and SI 2.1 weeks), except for an increased PI in January–March 2020 (median 2.7 weeks). Diagnostic intervals for T1DM during lockdown were similar to that in 2019 (TDI 16 vs 15 and PI 14 vs 14 days), except for an increased PI in January–March 2020 (median 21 days).

Conclusions

There is no evidence of diagnostic delay or increased illness severity for CC or T1DM, during the first phase of the pandemic across the participating centres. This provides reassuring data for children and families with these life-changing conditions.

Published: November 2021

Background

Eleven states have instituted laws allowing recreational cannabis use leading to growing public health concerns surrounding the effects of cannabis intoxication on driving safety. We hypothesized that after the 2016 legalization of cannabis in California, the use among vehicular injury patients would increase and be associated with increased injury severity.

Methods

San Diego County’s five adult trauma center registries in were queried from January 2010 to June 2018 for motor vehicle or motorcycle crash patients with completed toxicology screens. Patients were stratified as toxicology negative (TOX−), positive for only THC (THC+), only blood alcohol >0.08% (ETOH+), THC+ETOH, or THC+ with any combination with methamphetamine or cocaine (M/C). County medical examiner data were reviewed to characterize THC use in those with deaths at the scene of injury.

Results

Of the 11,491 patients identified, there were 61.6% TOX−, 11.7% THC+, 13.7% ETOH+, 5.0% THC+ETOH, and 7.9% M/C. THC+ increased from 7.3% to 14.8% over the study period and peaked at 14.9% post-legalization in 2017. Compared with TOX− patients, THC+ patients were more likely to be male and younger. THC+ patients were also less likely to wear seatbelts (8.5% vs 14.3%, p<0.001) and had increased mean Injury Severity Score (8.4±9.4 vs 9.0±9.9, p<0.001) when compared with TOX− patients. There was no difference in in-hospital mortality between groups. From the medical examiner data of the 777 deaths on scene, 27% were THC+.

Discussion

THC+ toxicology screens in vehicular injury patients peaked after the 2016 legalization of cannabis. Public education on the risks of driving under the influence of cannabis should be a component of injury prevention initiatives.

Recent Progress in Spermatology Contributing to the Knowledge and Conservation of Rare and Endangered Species
Authors: Comizzoli Pierre , Holt William V.
Published: November 2021

There is a remarkable diversity in the animal kingdom regarding mechanisms underlying the production, maturation, structure, and function of sperm cells. Spermatology studies contribute to the knowledge of species diversity and also provide information about individual or population fitness. Furthermore, this fundamental research is required before collected spermatozoa can be used for conservation breeding, including assisted reproduction and cryobanking. This article aims to ( a) review the most recent knowledge on sperm morphology and function in wild animal species, ( b) analyze how this knowledge can be used to save species in their natural habitat or ex situ, and ( c) propose future scientific directions in wildlife spermatology that could positively impact animal conservation. Variations in sperm structure and performance within and between species have multiple origins and significance. This collective body of knowledge enables the design and implementation of conservation strategies and action plans that integrate several disciplines.
Glue Semantics
Authors: Asudeh Ash
Published: November 2021

Glue Semantics (Glue) is a general framework for semantic composition and the syntax–semantics interface. The framework grew out of an interdisciplinary collaboration at the intersection of formal linguistics, formal logic, and computer science. Glue assumes a separate level of syntax; this can be any syntactic framework in which syntactic structures have heads. Glue uses a fragment of linear logic for semantic composition. General linear logic terms in Glue meaning constructors are instantiated relative to a syntactic parse. The separation of the logic of composition from structural syntax distinguishes Glue from other theories of semantic composition and the syntax–semantics interface. It allows Glue to capture semantic ambiguity, such as quantifier scope ambiguity, without necessarily positing an ambiguity in the syntactic structure. Glue is introduced here in relation to four of its key properties, which are used as organizing themes: resource-sensitive composition, flexible composition, autonomy of syntax, and syntax/semantics non-isomorphism.
In Situ Raman Spectroelectrochemical Doping of Monolayer Graphene at Micro-Scale

Published: November 2021

The chemical vapor deposited (CVD) graphene with large monolayer coverage is preferred for applications over the mechanical cleavage of graphite. Large-area graphene has a lot of potential in electrochemical applications, e.g., as electrodes for supercapacitors, smart windows etc. However, in contrast to the almost perfect cleaved graphene, the CVD samples are more heterogeneous and contain many defects and topographic features originating from the transfer process, all of which may influence the properties of the material. Therefore, it is important to study the electrochemical doping of graphene with such a lateral resolution that enables the assessment of the influence of the local structure on the electrochemical performance. The recently developed micro-droplet in-situ Raman spectroelectrochemical technique was used to provide insights into localized structural changes as a function of electrochemical doping as well as

other parasitic redox reactions at small area (few hundreds μm2) of the 1L CVD graphene. In all cases, we observed an extensive shift of the G peak with the disappearance of 2D peak and appearance of defects at higher potentials. The Raman frequency of the G peak was shifted by up to ⁓30 cm-1 for hole doping with all monovalent (LiCl, LiClO4,) divalent (Zn ClO4) and multivalent (AlCl3, Al(ClO4)3, Al(NO3)3) electrolyte salts. In addition, the onset potential of the defect formation and the initial doping state (the latter assessed from the G/2D frequency analysis) were studied.

Objective. Although importance of postpartum family planning is essential and immediate postpartum insertion of long acting and reversible contraceptives (LARC) is recommended, evidence on its uptake and associated factors is limited in Ethiopia. This study was conducted to assess utilization of immediate postpartum LARC among women who gave birth in selected public health facilities in eastern Ethiopia. Method. An institution-based cross-sectional study was conducted among randomly selected women who gave birth in selected public health facilities in eastern Ethiopia from 10 March to 09 April 2020. At discharge, all eligible women who gave birth in the facilities were interviewed using a pretested structured questionnaire. Data were entered using EpiData 3.1 and analyzed using SPSS 24. Bivariable and multivariable logistic regression analyses were conducted to identify factors associated with utilization of immediate postpartum LARC. Adjusted odds ratio (aOR) with 95% confidence interval was used to report association, and significance was declared at

Published: November 2021

A large number of accidents and scientific researches show that miners’ unsafe behavior affects coal mine safety production seriously. In order to effectively reduce the incidence of miners’ unsafe behavior, to improve their safety level, and reduce accidents caused by it, this paper used gray relational analysis method to analyze the miners’ unsafe behavior of W mine and quantitatively calculated the risk value of miners’ unsafe behavior. The results showed that the risk value of unsafe behavior in violation of labor discipline was 0.4358, which was much higher than that of other miners’ unsafe behaviors. Therefore, unsafe behavior in violation of labor discipline was determined as the key point of control in the next stage. Then, GM (1, 1) method was used to establish a predicted model for unsafe behavior, to predict the number of unsafe behaviors in violating labor discipline in next quarter, and to determine reasonable unsafe behavior control target. This study plays a driving role in controlling unsafe behaviors of miners and improving safe production water of coal mine.
Prediction of the VIV Responses Based on the Numerical Solutions of Controlled Motion
Authors: Yu Duanmu , Jianping Chen , Yizhong Chen
Published: November 2021

The study of forced and free vibration of a cylinder has long been isolated. The internal relationship between free vibration and forced vibration has rarely been investigated. In this paper, the relationship between the forced and free vibration of a cylinder was established. A series of numerical simulations of a cylinder undergoing forced oscillations at a wide range of vibration amplitudes and frequencies were carried out, with the flow solver viv‐FOAM‐SJTU developed based on the open‐source platform OpenFOAM. Complex demodulation analysis was conducted to quantify the spatial‐temporal phase relationship between the forces and the displacement of the cylinder. It was found that, at some particular oscillating amplitudes and frequencies, the phase angle switched between positive and negative values, which corresponds to a vortex mode transferring from the 2P mode to the 2PO mode. This distinct new mode “2PO” was closely related to the intermittent jumping between lower and upper branches of the amplitude responses of VIV. A prediction model was developed to obtain the VIV amplitude responses based on the numerical results of forced oscillation. The prediction results of three points located separately in the initial, upper, and lower branches of VIV agreed well with experimental measurements of an elastically mounted cylinder. This prediction model was thus expected to be suitable for predicting the response of VIV.

Published: November 2021

The prime objective of the current study is to examine the effects of third‐grade hybrid nanofluid with natural convection utilizing the ferro‐particle (Fe3O4) and titanium dioxide (TiO2) and sodium alginate (SA) as a host fluid, flowing through vertical parallel plates, under the fuzzy atmosphere. The dimensionless highly nonlinear coupled ordinary differential equations are computed adopting the bvp4c numerical approach. This is an extremely effective technique with a low computational cost. For validation, it is found that as the volume fraction of (Fe3O4 + TiO2) hybrid nanoparticles rises, so does the heat transfer rate. The current and existing results with their comparisons are shown in the form of the tables. The present findings are in good agreement with their previous numerical and analytical results in a crisp atmosphere. The nanoparticles volume fraction of Fe3O4 and TiO2 is taken as uncertain parameters in terms of triangular fuzzy numbers (TFNs) [0, 0.05, 0.1]. The TFNs are controlled by α − cut and the variability of the uncertainty is studied through triangular membership function (MF).
TPD: Temporal and Positional Computation Offloading with Dynamic and Dependent Tasks
Authors: Wang Mingzhi , Wu Tao , Fan Xiaochen , Sun Penghao , Qu Yuben , Yang Panlong
Published: November 2021

With the rapid development of wireless communication technologies and the proliferation of the urban Internet of Things (IoT), the paradigm of mobile computing has been shifting from centralized clouds to edge networks. As an enabling paradigm for computation‐intensive and latency‐sensitive computation tasks, mobile edge computing (MEC) can provide in‐proximity computing services for resource‐constrained IoT devices. Nevertheless, it remains challenging to optimize computation offloading from IoT devices to heterogeneous edge servers, considering complex intertask dependency, limited bandwidth, and dynamic networks. In this paper, we address the above challenges in MEC with TPD, that is, temporal and positional computation offloading with dynamic‐dependent tasks. In particular, we investigate channel interference and intertask dependency by considering the position and moment of computation offloading simultaneously. We define a novel criterion for assessing the criticality of each task, and we identify the critical path based on a directed acyclic graph of all tasks. Furthermore, we propose an online algorithm for finding the optimal computation offloading strategy with intertask dependency and adjusting the strategy in real‐time when facing dynamic tasks. Extensive simulation results show that our algorithm reduces significantly the time to complete all tasks by 30–60% in different scenarios and takes less time to adjust the offloading strategy in dynamic MEC systems.

Published: November 2021

Maintenance of normal function of mitochondria is vital to the fate and health of cardiomyocytes. Mitochondrial quality control (MQC) mechanisms are essential in governing mitochondrial integrity and function. The ubiquitin‐proteasome system (UPS), mitochondrial dynamics, and mitophagy are three major components of MQC. With the progress of research, our understanding of MQC mechanisms continues to deepen. Gradually, we realize that the three MQC mechanisms are not independent of each other. To the contrary, there are crosstalk among the mechanisms, which can make them interact with each other and cooperate well, forming a triangle interplay. Briefly, the UPS system can regulate the level of mitochondrial dynamic proteins and mitophagy receptors. In the process of Parkin‐dependent mitophagy, the UPS is also widely activated, performing critical roles. Mitochondrial dynamics have a profound influence on mitophagy. In this review, we provide new processes of the three major MQC mechanisms in the background of cardiomyocytes and delve into the relationship between them.

Authors: Gong Qingtao , Chen Zhanyang , Gui Hongbin , Yu Dong
Published: November 2021

The underwater acoustic radiation of the submarine power cabin has recently become a hot topic in the industry and also in the academia. In this article, the vibration and underwater acoustic radiation of a ring‐stiffened conical shell with bases are investigated numerically by means of the combination of the finite element method and boundary element method. The acoustic radiation field is obtained by the traditional acoustic field model and ISO acoustic field model, respectively. A series of numerical examples are given, and the results are compared. Besides, the sound pressure at different positions with frequency is further studied. It is shown that the sound radiated by the structure mainly propagates to the side directions of the shell and propagates relatively less to the front side and the rear side.

Authors: Swapna Lingam Amara , AlMegbil Nada Tarek , Almutlaq Alhanouf Othman , Koppolu Pradeep
Published: November 2021

Background. Patients with an elongated styloid process might present with dysphagia and pain in the cervicofacial region. These patients could be misdiagnosed as other orofacial pathologies. Aim. The present study attempted to assess the prevalence of the elongated styloid process on digital panoramic radiographs in the Riyadh population. Materials and Methods. The present prospective randomized study was conducted on the panoramic digital radiographs of 300 randomly selected patients visiting a private dental hospital to identify any elongation of the styloid process. Only the radiographs without any magnification errors were considered. The styloid process length was measured using the Sidexis measuring tool and entered in an Excel spreadsheet with other demographic data. A length beyond 30 mm was considered styloid process elongation. The data were subjected to statistical analysis. Results. The symptoms of styloid process elongation were higher among females (78.6%), and this difference was statistically significant (χ2 = 7.182;

P
=
0.007

). No statistically significant association was observed between styloid process elongation and symptoms between different age groups. Females exhibited a significant longer mean length of the styloid process than males. The present study exhibited a 27.3% prevalence for the elongation and calcification of the styloid process. Conclusion. Given the significant prevalence of the elongated styloid process in our study, we recommend it to be considered as one of the differential diagnosis for pain or discomfort in the orofacial region.
Convolutive Complex-Valued Independent Component Analysis for Nonlinear Radar Signal Processing and Maritime Weak Target Detection
Authors: Ghahramani Hamzeh , Parhizgar Naser , Abbasi Arand Bijan , Barari Morteza
Published: November 2021

This paper first establishes a new complex independent component analysis (cICA) algorithm based on the spatiotemporal extension of complex-valued entropy bound minimization (CEBM) to separate received complex-valued radar signals. Next, we propose a new cICA-based detector with an open structure to find Swerling model targets, lognormal targets, and sea-surface small floating targets in coherent high-resolution maritime surveillance radars. The detector encountered three major problems when adopting cICA for detection and solved them using three effective suggestions. After performing cICA on the time series received by the radar, we obtained two different sources. Using the first and second theoretical and empirical moment estimates of the K-distribution, the target was selected between these two output source signals. Detector performance was verified quantitatively and qualitatively using the real-life IPIX radar database. Comprehensive experiments on this database with synthetic injected targets showed promising results. The computational time and sample size dependency of the proposed cICA algorithm were also discussed. Finally, a comparison of the detector with several novel detectors for detecting sea-surface floating small targets of the IPIX radar database demonstrated the proposed detector’s superiority.
Microbiota, Bacterial Carbonic Anhydrases, and Modulators of Their Activity: Links to Human Diseases?
Authors: Amedei Amedeo , Capasso Clemente , Nannini Giulia , Supuran Claudiu T.
Published: November 2021

The involvement of the human microbiome is crucial for different host functions such as protection, metabolism, reproduction, and especially immunity. However, both endogenous and exogenous factors can affect the balance of the microbiota, creating a state of dysbiosis, which can start various gastrointestinal or systemic diseases. The challenge of future medicine is to remodel the intestinal microbiota to bring it back to healthy equilibrium (eubiosis) and, thus, counteract its negative role in the diseases’ onset. The shaping of the microbiota is currently practiced in different ways ranging from diet (or use of prebiotics, probiotics, and synbiotics) to phage therapy and antibiotics, including microbiota fecal transplantation. Furthermore, because microbiota modulation is a capillary process, and because many microbiota bacteria (both beneficial and pathogenic) have carbonic anhydrases (specifically the four classes α, β, γ, and ι), we believe that the use of CA inhibitors and activators can open up new therapeutic strategies for many diseases associated with microbial dysbiosis, such as the various gastrointestinal disorders and the same colorectal cancer.

Similarity measures (SM) and correlation coefficients (CC) are used to solve many problems. These problems include vague and imprecise information, excluding the inability to deal with general vagueness and numerous information problems. The main purpose of this research is to propose an m‐polar interval‐valued neutrosophic soft set (mPIVNSS) by merging the m‐polar fuzzy set and interval‐valued neutrosophic soft set and then study various operations based on the proposed notion, such as AND operator, OR operator, truth‐favorite, and false‐favorite operators with their properties. This research also puts forward the concept of the necessity and possibility operations of mPIVNSS and also the m‐polar interval‐valued neutrosophic soft weighted average operator (mPIVNSWA) with its desirable properties. Cosine and set‐theoretic similarity measures have been proposed for mPIVNSS using Bhattacharya distance and discussed their fundamental properties. Furthermore, we extend the concept of CC and weighted correlation coefficient (WCC) for mPIVNSS and presented their necessary characteristics. Moreover, utilizing the mPIVNSWA operator, CC, and SM developed three novel algorithms for mPIVNSS to solve the multicriteria decision‐making problem. Finally, the advantages, effectiveness, flexibility, and comparative analysis of the developed algorithms are given with the prevailing techniques.
A Novel Development of TRIZ‐Analogic Construction Interface Problem Identification and Solutions Framework
Authors: Leu Sou-Sen , Yang Chih-Yu , Hsu Yao-Jen
Published: November 2021

One of the critical factors of project success is the interface management. Past project interface management mainly relies on knowledge and experience of the project managers. The existing studies of project interface management also mainly focused on the definition and the classification of project interfaces. There is no workable and flexible framework for construction interface problem identification and solutions. This study conducted an analogic study of contradiction matrix at Theory of Inventive Problem Solving (TRIZ) to develop such a framework. This research collected around six hundred interface management cases from civil works and building projects. For comparison, this research defined an experimental group (TRIZ case) and a control group (experience‐oriented solution case) based on the concept of clinical experiments in medical science to evaluate and improve the rationality of the matrix. Subsequently, based upon the theory of information retrieval (IR), this research conducted statistical evaluation and TRIZ features remedies to develop generalized construction interface problem identification and solutions. For solving project management interface problems, the TRIZ‐analogic construction interface problem identification and solutions framework provides a systematic approach to develop more robust solutions for interface problems in construction engineering rather than just simply relying on intuitive experience.

Authors: Sharma Richa , Sharma Manoj , Shukla Ankit , Chaudhury Santanu
Published: November 2021

Generation of synthetic data is a challenging task. There are only a few significant works on RGB video generation and no pertinent works on RGB-D data generation. In the present work, we focus our attention on synthesizing RGB-D data which can further be used as dataset for various applications like object tracking, gesture recognition, and action recognition. This paper has put forward a proposal for a novel architecture that uses conditional deep 3D-convolutional generative adversarial networks to synthesize RGB-D data by exploiting 3D spatio-temporal convolutional framework. The proposed architecture can be used to generate virtually unlimited data. In this work, we have presented the architecture to generate RGB-D data conditioned on class labels. In the architecture, two parallel paths were used, one to generate RGB data and the second to synthesize depth map. The output from the two parallel paths is combined to generate RGB-D data. The proposed model is used for video generation at 30 fps (frames per second). The frame referred here is an RGB-D with the spatial resolution of 512 × 512.

Published: November 2021

A decentralized control strategy can effectively solve the control problem of the large‐scale time delayed structures. In this paper, combining the overlapping decentralized control method, linear matrix inequality (LMI) method, and H∞ control algorithm, overlapping decentralized H∞ control approach of the time delayed structures has been established. The feedback gain matrixes of all subsystems are obtained by this method based on genetic algorithm optimization tools and the specific goal of optimization control. The whole vibration control system of the time delayed structures is divided into a series of overlapping subsystems by overlapping decentralized control strategy. The feedback gain matrixes of each subsystem can be obtained by using H∞ control algorithm to calculate each subsystem. The vibration control of a twenty layers’ antiseismic steel structure Benchmark model was analyzed with the numerical method. The results show that the proposed method can be applied to control system with time delay. The overlapping decentralized control strategies acquire the similar control effects with that of the centralized control strategy. Moreover, the flexibility of the controller design has been enhanced by using overlapping decentralized control strategies.

Authors: Zhao Qiang
Published: November 2021

Over the last two decades, the identification of ancient artifacts has been regarded as one of the most challenging tasks for archaeologists. Chinese people consider these artifacts as symbols of their cultural heritage. The development of technology has helped in the identification of ancient artifacts to a greater extent. The study preferred machine‐learning algorithms to identify the ancient artifacts found throughout China. The major cities of China were selected for the study and classified the cities based on different features like temple, modern city, harbour, battle, and South China. The study used a decision tree algorithm for recognition and gradient boosting for perception aspects. According to the findings of the study, the algorithms produced 98% accuracy and prediction in detecting ancient artifacts in China. The proposed models provide a good indicator for detecting archaeological site locations.
Infancias y colecho en la Argentina: factores sociodemográficos, socioeconómicos y de salud familiar
Authors: Tuñón Ianina , Sánchez Carolina Emilia
Published: November 2021

(analítico)Se caracteriza el fenómeno del colecho en términos sociodemográficos, socioeconómicos y en relación con las vulnerabilidades específicas de los hogares, tales como la violencia intrafamiliar y los consumos nocivos. A través de la Encuesta de la Deuda Social Argentina y un análisis multivariado cuantitativo, se abordan los siguientes interrogantes: ¿el colecho es una práctica asociada únicamente a los bebés?, ¿resulta más frecuente en contextos de pobreza o se trata de una práctica que atraviesa a diferentes infancias? Se concluye que el colecho no es un fenómeno exclusivo de los y las bebés; que en la adolescencia es más regresivo para las mujeres y que el factor socioeconómico remite a un «colecho forzoso» que se especifica en interacción con el hacinamiento, la monoparentalidad, los consumos nocivos y la violencia intrafamiliar.

Entre o cristianismo e uma tradição forjada: a Jerusalén conquistada, de Lope de Vega
Authors: Monteiro Wagner
Published: November 2021

Este artigo tem como objetivo localizar a Jerusalén conquistada de Lope de Vega dentro de sua produção religiosa e dos Séculos de Ouro na Espanha. Publicada em 1609, a Jerusalén é fruto do mais ambicioso projeto de Lope de Vega, escritor espanhol famoso pelo teatro, mas que escreveu diversos poemas épicos entre o final do século XVI e nas primeiras décadas do XVII. Lançando mão do modelo italiano de Torquato Tasso, com sua Gerusalemme liberata (1581), Lope construiu sua narrativa para enaltecer a corte espanhola dos Austrias e, ao mesmo tempo, para adquirir em solo espanhol o status que Luís de Camões havia alcançado em Portugal.

Background:

Many heart diseases can result in reduced pumping capacity of the heart muscle. A mismatch between ATP demand and ATP production of cardiomyocytes is one of the possible causes. Assessment of the relation between myocardial ATP production (MV
ATP
) and cardiac workload is important for better understanding disease development and choice of nutritional or pharmacologic treatment strategies. Because there is no method for measuring MV
ATP
in vivo, the use of physiology-based metabolic models in conjunction with protein abundance data is an attractive approach.

METHOD:

We developed a comprehensive kinetic model of cardiac energy metabolism (CARDIOKIN1) that recapitulates numerous experimental findings on cardiac metabolism obtained with isolated cardiomyocytes, perfused animal hearts, and in vivo studies with humans. We used the model to assess the energy status of the left ventricle of healthy participants and patients with aortic stenosis and mitral valve insufficiency. Maximal enzyme activities were individually scaled by means of protein abundances in left ventricle tissue samples. The energy status of the left ventricle was quantified by the ATP consumption at rest (MV
ATP
[rest]), at maximal workload (MV
ATP
[max]), and by the myocardial ATP production reserve, representing the span between MV
ATP
(rest) and MV
ATP
(max).

Results:

Compared with controls, in both groups of patients, MV
ATP
(rest) was increased and MV
ATP
(max) was decreased, resulting in a decreased myocardial ATP production reserve, although all patients had preserved ejection fraction. The variance of the energetic status was high, ranging from decreased to normal values. In both patient groups, the energetic status was tightly associated with mechanic energy demand. A decrease of MV
ATP
(max) was associated with a decrease of the cardiac output, indicating that cardiac functionality and energetic performance of the ventricle are closely coupled.

Conclusions:

Our analysis suggests that the ATP-producing capacity of the left ventricle of patients with valvular dysfunction is generally diminished and correlates positively with mechanical energy demand and cardiac output. However, large differences exist in the energetic state of the myocardium even in patients with similar clinical or image-based markers of hypertrophy and pump function.

Confidence-Controlled Hebbian Learning Efficiently Extracts Category Membership From Stimuli Encoded in View of a Categorization Task
Authors: Berlemont Kevin , Nadal Jean-Pierre
Published: November 2021

In experiments on perceptual decision making, individuals learn a categorization task through trial-and-error protocols. We explore the capacity of a decision-making attractor network to learn a categorization task through reward-based, Hebbian-type modifications of the weights incoming from the stimulus encoding layer. For the latter, we assume a standard layer of a large number of stimulus-specific neurons. Within the general framework of Hebbian learning, we have hypothesized that the learning rate is modulated by the reward at each trial. Surprisingly, we find that when the coding layer has been optimized in view of the categorization task, such reward-modulated Hebbian learning (RMHL) fails to extract efficiently the category membership. In previous work, we showed that the attractor neural networks' nonlinear dynamics accounts for behavioral confidence in sequences of decision trials. Taking advantage of these findings, we propose that learning is controlled by confidence, as computed from the neural activity of the decision-making attractor network. Here we show that this confidence-controlled, reward-based Hebbian learning efficiently extracts categorical information from the optimized coding layer. The proposed learning rule is local and, in contrast to RMHL, does not require storing the average rewards obtained on previous trials. In addition, we find that the confidence-controlled learning rule achieves near-optimal performance. In accordance with this result, we show that the learning rule approximates a gradient descent method on a maximizing reward cost function.
Bridging the Functional and Wiring Properties of V1 Neurons Through Sparse Coding
Authors: Hu Xiaolin , Zeng Zhigang
Published: November 2021

The functional properties of neurons in the primary visual cortex (V1) are thought to be closely related to the structural properties of this network, but the specific relationships remain unclear. Previous theoretical studies have suggested that sparse coding, an energy-efficient coding method, might underlie the orientation selectivity of V1 neurons. We thus aimed to delineate how the neurons are wired to produce this feature. We constructed a model and endowed it with a simple Hebbian learning rule to encode images of natural scenes. The excitatory neurons fired sparsely in response to images and developed strong orientation selectivity. After learning, the connectivity between excitatory neuron pairs, inhibitory neuron pairs, and excitatory-inhibitory neuron pairs depended on firing pattern and receptive field similarity between the neurons. The receptive fields (RFs) of excitatory neurons and inhibitory neurons were well predicted by the RFs of presynaptic excitatory neurons and inhibitory neurons, respectively. The excitatory neurons formed a small-world network, in which certain local connection patterns were significantly overrepresented. Bidirectionally manipulating the firing rates of inhibitory neurons caused linear transformations of the firing rates of excitatory neurons, and vice versa. These wiring properties and modulatory effects were congruent with a wide variety of data measured in V1, suggesting that the sparse coding principle might underlie both the functional and wiring properties of V1 neurons.

Published: November 2021

The Adiantum pedatum complex is disjunctly distributed in North America and eastern Asia. In this study, we carried out a detailed morphological study based on 137 specimens representing the biogeographic diversity of this complex. The sequences of eight chloroplast markers of 35 samples were analyzed with maximum likelihood and Bayesian inference. The morphological and phylogenetic analyses support the recognition of a new species of the A. pedatum complex from Japan. We propose the new species as A. japonicum based on the examinations of specimens from Japan and the comparative analyses of the whole complex. This new species can be distinguished from A. pedatum by the erect rhizome and shows significant molecular differences from other species in this complex. A taxonomic description with detailed morphological characters of the new species is presented.
Two noteworthy ramicolous liverworts from Mount Roraima, Guyana: Frullania trigona and Metzgeria deniseana sp. nov.

Published: November 2021

Mount Roraima, at the geographical tripoint of Brazil, Guyana and Venezuela, is famous for its richness in rare and endemic species. Here we report two unusual ramicolous liverwort species from the north ridge of the mountain, located within the borders of the country of Guyana: Frullania (sect. Microphyllae) trigona and Metzgeria deniseana sp. nov. Frullania section Microphyllae is a group of ten species within subgenus Frullania, distributed in eastern Asia, Europe and tropical America, and characterized by the small dioicous plants with ocelli, caducous leaf lobes and tiny underleaves. Frullania trigona is one of the rarest species of the section and was only known from the type collection from Guadeloupe. It is recognized by the obclavate lobules with a very small mouth, leaf margins with protruding whitish trigones and the presence of a huge attachment cell at the dorsal leaf bases. The latter two features are unusual in Frullania and are unique to F. trigona. Metzgeria deniseana is a new member of the genus Metzgeria with saccate thallus lobes (= former genus Austrometzgeria) and stands out by the very irregular shaped sacs, varying from subglobose to strongly elongate, thallus margins with a wide and ill-defined border, and strongly convex gemmae with revolute margins. The discovery of Frullania trigona and Metgeria deniseana adds two further noteworthy species to the rich liverwort flora of Mount Roraima.

Authors: DA SILVA MARCOS JOSÉ
Published: November 2021

Justicia pusilla, a new species of Acanthaceae from Brazil, is described and illustrated. The new species is one of the smallest plants in the genus. It is morphologically allied with Justicia laevilinguis and “Justicia indespecta”, but differs from both by a set of characters related to habit, leaves, spikes, bracts, bracteoles, calyx, corolla and seeds. It is considered endangered due to its restricted geographic distribution and low population density.
