Avi Hazan1, Elishai Ezra Tsur1*1 Neuro-Biomorphic Engineering Lab, Department of Mathematics and Computer Science, The Open University of Israel, Ra’anana, Israel* Correspondence: elishai@NBEL-lab.comAbstractNeuromorphic hardware designs realize neural principles in electronics to provide high-performing, energy-efficient frameworks for machine learning. Here, we propose a neuromorphic analog design for continuous real-time learning. Our hardware design realizes the underlying principles of the neural engineering framework (NEF). NEF brings forth a theoretical framework for the representation and transformation of mathematical constructs with spiking neurons. Thus, providing efficient means for neuromorphic machine learning and the design of intricate dynamical systems. Our analog circuit design implements the neuromorphic prescribed error sensitivity (PES) learning rule with OZ neurons. OZ is an analog implementation of a spiking neuron, which was shown to have complete correspondence with NEF across firing rates, encoding vectors, and intercepts. We demonstrate PES-based neuromorphic representation of mathematical constructs with varying neuron configurations, the transformation of mathematical constructs, and the construction of a dynamical system with the design of an inducible leaky oscillator. We further designed a circuit emulator, allowing the evaluation of our electrical designs on a large scale. We used the circuit emulator in conjunction with a robot simulator to demonstrate adaptive learning-based control of a robotic arm with six degrees of freedom.

Background: Uncomplicated type B aortic dissection (un-TBAD) has been managed conservatively with medical therapy in order to control the heart rate and blood pressure to limit disease progression, in addition to radiological follow-up. However, several trials and observational studies have investigated the use of thoracic endovascular aortic repair (TEVAR) in un-TBAD and suggested that TEVAR provides a survival benefit over medical therapy. Outcomes of TEVAR have also been linked with the timing of intervention. Aims: The scope of this review is to collate and summarise all the evidence in the literature on the mid- and long-term outcomes of TEVAR in un-TBAD, confirming its superiority. We also aimed to investigate the relationship between timing of TEVAR intervention and results. Methods: We carried out a comprehensive literature search on multiple electronic databases including PubMed, Scopus and EMBASE in order to collate and summarise all research evidence on the mid- and long-term outcomes of TEVAR in un-TBAD, as well as its relationship with intervention timing. Results: TEVAR has proven to be a safe and effective tool in un-TBAD, offering superior mid- and long-term outcomes including all-cause and aorta-related mortality, aortic-specific adverse events, aortic remodelling, and need for reintervention. Additionally, performing TEVAR during the subacute phase of dissection seems to yield optimal results. Conclusion: The evidence demonstrating a survival advantage in favour TEVAR over medical therapy in un-TBAD means that with further research, particular trials and observational studies, TEVAR could become the gold-standard treatment option for un-TBAD patients.

This paper provides a simplified solution of the Dirac equation for the pure rotational energy of the diatomic molecules and a discussion of the non-relativistic limit. The last works [1-2] led to a complicated form of the relativistic energy of the molecular rotation-vibrational energy with high computational cost based on Schrodinger-like equation. The present work provides a way to determine the pure rotational energy without exclusion of the wavefunction components or using the Schrodinger-like equation, where the selection rule ΔJ=±1, where J is the rotational quantum number, appears as a prerequisite for solving the equations. Based on the anti-hermitian spin-orbit operator (L∼) that been introduced in this paper, which excludes the derivatives, the computational cost expects to decrease.

Secondary contact of species that have evolved partial reproductive isolation in allopatry may result in several outcomes, which range from rampant hybridization to barrier reinforcement. Reinforcement arises from reduced hybrid fitness, which promotes assortative mating and hence speciation. In plants, self-fertilization and disjunction in reproductive phenology are often cited as evidence of reinforcement. However, local adaptation and pleiotropic effects during colonization can also lead to reproductive isolation without reinforcement. We explored these competing possibilities in a fir species complex (Abies flinckii - A. religiosa) distributed in ‘sky-islands’ along the Trans-Mexican Volcanic Belt (TMVB), in central Mexico. Despite co-occurring in two independent sympatric regions (west and center), these two taxa seem to rarely interbreed because of disjunct reproductive phenologies. We genotyped 1,147 SNPs, generated by GBS across 23 populations, and compared multiple demographic scenarios, built based on the geological history of the TMVB. The best-fitting model revealed one of the most rapid and complete speciation cases for a conifer species-pair, dating back to ~1.2 Ma, which included an early asymmetric gene flow (mostly from A. flinckii into A. religiosa) limited to the most ancient sympatric region. Coupled with the lack of support for colonization models, our demographic inferences point to an early development of reinforcement, as a putative mechanism for avoiding hybridization. Reinforcement should be considered as a key player for originating and maintaining species diversity in the tropics and subtropics and incorporated in studies with other model systems.

The dynamics of cyclic populations distributed in space result from the relative strength of synchronising influences and the limited dispersal of destabilising factors (activators and inhibitors), known to cause multi-annual population cycles. However, while each of these have been well studied in isolation, there is limited empirical evidence about how the processes of synchronisation and activation-inhibition act together, largely owing to the scarcity of datasets with sufficient spatial and temporal scale. We assessed a variety of models that could be underlying the spatio-temporal pattern, designed to capture both theoretical and empirical understandings of travelling waves using large-scale (> 35,000 km2), multi-year (2011-2017) field monitoring data on abundances of common vole (Microtus arvalis), a cyclic agricultural rodent pest. We found most support for a pattern formed from the summation of two radial travelling waves with contrasting speeds that together describe population growth rates across the region.

1) Results of ossiculoplasty via trans-canal endoscopic (TEES) route is comparable to that of the traditional microscopic approach 2) There was no difference in complications or secondary outcomes such as tympanic membrane residual perforation or ear discharge between these groups 3) Both groups achieved an air-bone gap of less that 20dB in more than 70% of the cases 4) In our experience there was no difference in outcomes based on ossiculoplasty material such as cartilage, titanium prosthesis or autologous grafts such as incus. 5) Eroded stapes superstructure is does not preclude getting improvements in ABG of less than 20dB, but larger studies with longer follow ups might be useful.

In heterogeneous landscapes, habitat preference constitutes a crucial link between landscape and population-level processes such as density and sex ratios. We conducted a non-invasive genetic study of white-tailed deer in southern Finland using fecal samples. We estimated deer density as a function of landcover type using a Spatial Capture-Recapture (SCR) model. Second-order habitat selection of white-tailed deer revealed particularly high densities in fields and mixed forest, and third-order selection was related to distance to fields and transitional woodlands (clearcuts). Including landscape heterogeneity improved model fit compared with assuming a homogenous landscape. Our findings underline the importance of including habitat covariates when estimating density.

Deterministic models have difficulties to take into account stochasticity during community assembly. As a tool to circumvent this problem, we present a qualitative discrete-event model, where consequences of interspecific interactions are described as rules. This model provides a map of all possible future dynamics for a given system, which allows to exhaustively describe the possible pathways during an assembly process. Such a description does not rely on species traits details and is insensitive to stochastic effects. This allows to show that subsets of species are sometimes impossible to reach starting from larger sets of species, and therefore to question the reachability of community states during the system's dynamics. Applying the model to an experimental dataset studying the collapse of protist communities, we obtain a very good theory-experiment agreement. We finally discuss what the notion of reachability can bring to community assembly.

eDNA metabarcoding is an effective method for studying fish communities but allows only an estimation of relative species abundance (density / biomass). Here, we combine metabarcoding with an estimation of the total abundance of eDNA amplified by our universal marker (teleo) using a qPCR approach to infer the absolute abundance of fish species. We carried out a 2850 km eDNA survey within the Danube catchment using a spatial integrative sampling protocol coupled with traditional electrofishing for fish biomass and density estimation. Total fish eDNA concentrations and total fish abundance were highly correlated. The correlation between eDNA concentrations per taxon and absolute specific abundance was of comparable strength when all sites were pooled and remained significant when the sites were considered separately. Furthermore, a non-linear mixed model showed that species richness was underestimated when the amount of teleo-DNA extracted from a sample was below a threshold of 0.65.106 copies of eDNA. This result, combined with the decrease in teleo-DNA concentration by several orders of magnitude with river size, highlights the need to increase sampling effort in large rivers. Our results show a comprehensive description of longitudinal changes in fish communities and underline our combined metabarcoding/qPCR approach for biomonitoring and bioassessment surveys when a rough estimate of absolute species abundance is sufficient.

Climate change is considered to affect the species distribution deeply in time and space. Knowledge of how plant distribution responded to climate change may help us know their evolutionary history and predict ongoing environmental changes. Elevational range shifts of species in response to climate change is a common phenomenon in mountains, especially for the closely related species in sympatric. Here, we selected Taxus chinensis and Taxus mairei to explore this issue. Four types of environmental variables were used to simulate the distribution patterns, under the historical climate and future climate change scenarios, with the optimization Maxent model. We found that elevational distribution of two species has significant differences. The distribution of T. chinensis was higher than that of T. mairei. The centroid of T. chinensis and T. mairei were in Sichuan and Hunan province, respectively. Temperature and precipitation were the main factors that determine the potential distribution of the two species, and the suitable distribution area of T. chinensis was lower than T. mairei. In the future, the direction of centroid migration of two species was almost opposite, T. chinensis will shift southwest while T. mairei go northeast. Our results not only provided an insight to discriminate two sympatric species in subtropical and warm temperature zones, but also gave us an important reference for the conservation of these valuable endangered species.

Iron (Fe) deficiency restricts crop yields in calcareous soil. Thus, a novel Fe chelator, proline-2′-deoxymugineic acid (PDMA), based on the natural phytosiderophore 2′-deoxymugineic acid (DMA), was developed to solve the Fe deficiency problem. However, the effects and mechanisms of PDMA relevant to the Fe nutrition and yield of dicots grown under field conditions require further exploration. In this study, pot and field experiments with calcareous soil were conducted to investigate the effects of PDMA on the Fe nutrition and yield of peanuts. The results demonstrate that PDMA could dissolve insoluble Fe in the rhizosphere and up-regulate expression of the yellow stripe-like family gene AhYSL1 to improve the Fe nutrition of peanuts. Moreover, the chlorosis and growth inhibition induced by Fe deficiency were significantly diminished. Importantly, under field conditions, the peanut yield and kernel micronutrition were notably promoted by PDMA application. Our results indicate that PDMA promotes the dissolution of insoluble Fe and a rich supply of Fe in the rhizosphere, increasing yields through integrated improvements in soil–plant Fe nutrition at the molecular and ecological levels. In conclusion, the efficacy of PDMA for improving the Fe nutrition and yield of peanut indicates its outstanding potential for agricultural applications.

Interpretability of neural networks is crucial in developing trust between humans and machines and human's ability to take decisions based on the outputs of neural networks. In this paper, the role observer/interpreter in the interpretability is discussed, where interpretability refers to the confidence an arbitrary observer has in the decisions based on the outputs from output generating systems and observer can be a machine or a human. The first step in the interpretability is to ascribe meaning to the output which observer receives from the system. To ascribe meaning, binary system representation scheme is employed where an output is a unique configuration of n binary systems. Furthermore, it has been shown that outputs of neural networks and dreams are fundamentally equivalent, given that observer employs same representation scheme. Lastly, two governing factors in interpretability; observer's understanding of the phenomena and prior performance data of output generating system pertaining to phenomena are qualitatively discussed, taking inspiration from chess.
