Valuations of Skew Quantum Polynomials

In this paper we extend some results obtained by Artamonov and Sabitov for quantum polynomials to skew quantum polynomials and quasi-commutative bijective skew PBW extensions. Moreover, we find a counterexample to the conjecture proposed in [6]Comment: arXiv admin note: text overlap with arXiv:1309.0483, arXiv:1402.2321, arXiv:1310.6639 by other author

Ore and Goldie theorems for skew PBW extensions

Many rings and algebras arising in quantum mechanics can be interpreted as skew PBW (Poincar\'e-Birkhoff-Witt) extensions. Indeed, Weyl algebras, enveloping algebras of finite-dimensional Lie algebras (and its quantization), Artamonov quantum polynomials, diffusion algebras, Manin algebra of quantum matrices, among many others, are examples of skew PBW extensions. In this paper we extend the classical Ore and Goldie theorems, known for skew polynomial rings, to this wide class of non-commutative rings. As application, we prove the quantum version of the Gelfand-Kirillov conjecture for the skew quantum polynomials

The network structure of depressive symptomatology in Peruvian adults with arterial hypertension

"Background: Globally, arterial hypertension (AH) has increased by 90% over the last four decades, and has increased by 1.6% in Peru over the previous four years. Scientific evidence indicates the prevalence of depressive symptoms in patients with AH and its importance in the comprehensive evaluation of the adult for adherence to clinical treatment. Previous studies carried out in the Peruvian population with AH mostly report the prevalence and associations, but do not indicate which depressive symptoms are more relevant in patients with AH. This study involved a network analysis of depressive symptomatology in Peruvian patients with AH using network estimation. Network analysis is used in this study for analysis, control, and monitoring purposes. Method: A representative cross-sectional study at the national level, using secondary data from 2019 Demographic and Family Health Survey (ENDES) was performed. The sample used included men and women of age over 17 years diagnosed with AH and was able to respond to Patient Health Questionnaire-9 (PHQ-9). Results: The symptoms of depressive mood (bridging force and centrality) and energy fatigue or loss (bridge centrality) play an essential role in the network structure, as does the feeling of uselessness in terms of closeness and intermediation. Conclusion: The study highlighted the symptoms related to depressive mood and energy fatigue or loss as bridging symptoms, which could trigger a depressive episode in patients diagnosed with AH. The results will contribute to developing personalized treatments aimed at patients with specific depressive symptoms who have also been diagnosed with AH. The study analysis presents statistical coefficients of effect size (≤ 0,1 = small; > 0,1 to < 0,5 = moderate; ≥ 0,5 = large) to determine network connections.

The Hochschild (co)homology of gentle algebras

In this paper, we calculate the complete Tamarkin Tsygan calculus for gentle algebras. For this we give a complete description of the structure of the Hochschild cohomology ring of a gentle algebra both as a graded commutative algebra and as Gerstenhaber algebra. Furthermore, we show how these structures are encoded in the geometric surface model of the bounded derived category associated to a gentle algebra via its ribbon graph. We also compute the Hochschild homology, the cyclic homology, the Connes' map and the right module structure of the Hochschild homology over the Hochschild cohomology ring via the cap product.Comment: 107 pages, 12 figures, 5 table

RetrOryza: a database of the rice LTR-retrotransposons

Long terminal repeat (LTR)-retrotransposons comprise a significant portion of the rice genome. Their complete characterization is thus necessary if the sequenced genome is to be annotated correctly. In addition, because LTR-retrotransposons can influence the expression of neighboring genes, the complete identification of these elements in the rice genome is essential in order to study their putative functional interactions with the plant genes. The aims of the database are to (i) Assemble a comprehensive dataset of LTR-retrotransposons that includes not only abundant elements, but also low copy number elements. (ii) Provide an interface to efficiently access the resources stored in the database. This interface should also allow the community to annotate these elements. (iii) Provide a means for identifying LTR-retrotransposons inserted near genes. Here we present the results, where 242 complete LTR-retrotransposons have been structurally and functionally annotated. A web interface to the database has been made available (), through which the user can annotate a sequence or search for LTR-retrotransposons in the neighborhood of a gene of interest

Design and fabrication of integral carbon monoliths combining 3D printing and sol-gel polymerization: effect of the channels morphology on the CO-PROX reaction

The authors acknowledge the financial support from the Spanish Ministry of Science and Innovation (PID2019-105960RB-C22), the University of Alicante (Project GRE18-01A), the Generalitat Valenciana (Projects PROMETEO/2018/076 and GV2020-075, PhD grant GRISOLIAP/2017/177 and contract APOSTD/2019/030), the Junta de Andalucia (Project P18-RTJ-2974) and the UE (FEDER funding).A new method to synthesize integral carbon monoliths with a controlled channel morphology has been developed in this work by combining 3D-printing technology and sol–gel polymerization. By this method, robust and consistent carbon monoliths were obtained with a perfect replica of the channel architecture at a microscale range. As a proof of concept, a carbon monolith with tortuous channels that split and join successively along the monolith length has been designed, fabricated and tested as a CuO/CeO2 support for the preferential oxidation of CO in the presence of H2 (CO-PrOx), which is a topic of ongoing research for H2 purification in fuel cells. The behavior of this novel carbon monolith catalyst has been compared with that of a counterpart catalyst prepared with a conventional honeycomb design. Results shown that the wide macroporosity of the carbon network favors the anchoring and dispersion of the active phase both in the channel surface and the carbon network. The channel architecture affects the gas diffusion both through the channel and the carbon network and consequently, affects the active phase accessibility and activity. T50 (the temperature to achieve 50% CO conversion) decreases by almost 13 °C at 240 mL min−1 in the carbon monolith with tortuous channels (T50 = 79.7 °C) compared to the honeycomb monolith (T50 = 93.1 °C). The turbulent path created by the tortuous channels favours the active phase–gas contact and even the gas diffusion inside the macropores of the carbon skeleton improving the catalytic performance of the active phase compared to that by the conventional honeycomb design. Thus, this work demonstrates the potential of 3D printing to improve the catalytic supports currently available.Spanish Government PID2019-105960RB-C22University of Alicante GRE18-01AGeneralitat ValencianaEuropean CommissionGeneral Electric PROMETEO/2018/076 GV2020-075 GRISOLIAP/2017/177 APOSTD/2019/030Junta de Andalucia P18-RTJ-2974UE (FEDER funding
