LA TRANSCRIPCIÓN MUSICAL FLAMENCA: ENTRE LA CIENCIA Y EL ARTE
Authors: Hurtado Torres David 
Published: March 2023

En el mundo del Flamenco ha existido una especie de dogma histórico que propugnaba la imposibilidad de capturar la música entre las cinco líneas del pentagrama. Lapartitura, por precisa que sea, no podrá recoger determinados aspectos concernientes a la interpretación, que como hemos visto, se adquieren por otros procedimientos mas o menos relacionados con la transmisión oral. La correspondencia entre una partitura y el fenómeno musical real que trata de representar, nunca llega a ser absoluta nipor asomo.
VIOLÍN Y VIOLINISTA: UNA RELACIÓN SIEMPRE VIVA.
Authors: Almansa Pérez Encarnación 
Published: March 2023

Si partimos de la idea de que los autores de tratados pretenden refleiar la problemática del intérprete en cada momento, quizá deberíamos reconocer que, en la actualidad, el principal reto de los violinistas es el de ser capaces de sobrellevar la profesión una vez que se ha alcanzado un nivel básico. Le violon interieur, ensayo de la violinistafrancesa Dominique Hoppenot, goza de amplio reconocimiento, parte de la premisa de que el intérprete necesita un desarrollo integral, entendido éste como toma deconciencia cada vez mayor de sí mismo, como control creciente de su cuerpo y de su mente.
TRAS LA HUELLA DEL DUENDE FLAMENCO A TRAVÉS DEL ANÁLISIS.
Authors: Cera Vera Manuel 
Published: March 2023

El común de los artistas y aficionados de este singular arte coincide en considerar la grata, impródiga y enigmática visita del duende como la cota comunicativa suprema, la emoción última y primera que hace que unos y otros, emisores y receptores artísticos, se fundan en una intensa emoción de infinita amargura, catarsis y belleza a la vez. La guitarra flamenca construye sus toques solistas por soleá sobre el mismo núcleo expresivo del cante, sustituyendo al mismo por sus propias melodías. Como ocurre con todas las soleares de Paco de Lucía, ésta que contiene la falseta que analizamos ahora es de una elaboración rítmico- melódica magistral.

EL ENSAYO: PRÁCTICA DE CONJUNTO.
Authors: Gallardo Lorenzo Luis Rubén 
Published: March 2023

La necesidad de interacción ronda alrededor de la vidad de todo intérpre. La interacción, como concepto, transgrede lo netamente musical y nos sitúa en diferentesplanos de actitud social, de integración de ideas y de práctica activa de tolerancia al prójimo constituyendo una parte fundamental de aquello que venimos a definir como ser profesional en el marco del oficio de músico. El ensayo es el momento en el que varios profesionales creativos se sumergen juntos en una búsqueda colectiva donde lo individual es imprescindible, una integración de voluntades que, a priori, eran irreconciliables. Suge la necesidad de dedicar una breve reflexión donde se sinteticenlas esencias de este trabajo en equipo, tanto como referencia para estudiantes y profesionales de la música, como para el lector ajeno a esta actividad que pudiera ver en este artículo una posible referencia para extrapolar a otros contextos.
Virtual Multiphase Flowmeter Using Deep Convolutional Neural Networks
Authors: Mercante Renata , Netto Theodoro Antoun 
Published: March 2023

Summary
Petroleum wells produce a combination of oil, gas, and water in what is called a multiphase flow. This mixture is transported through flowlines to a tank separator that isolates and quantifies the volume of each fluid. However, this mechanical gravity separation process takes a long time, and the tank is often shared between many other wells in a field, making it difficult to allow an individual online measurement of the extracted fluids. Without this information, operators cannot effectively control production or estimate each well’s depletion rate, leading to losses or reduced profits. This paper aims to propose a low-cost, instantaneous model to perform this measure using artificial intelligence, commonly known as a virtual flowmeter (VFM). The idea behind it is to use data from pressure and temperature sensors already available on every well in addition to the state of the opening control valve to train a deep neural network with a convolutional layer to output each fluid’s volume rate. The proposed method is computationally simpler than recurrent neural networks and provides similar results. However, it still requires data to train the neural network. Adequate free databases of well production with telemetry are hard to find, so this paper proposes using the Schlumberger OLGA multiphase flow simulator software to provide the data, adjusting the simulator with fluid and operational information from actual wells. Tests have shown that the approximation with the proposed methods achieves up to 99.6% accuracy, making it possible to replace an expensive multiphase meter or use it as a redundant digital sensor for fault alerts of possible inaccurate readings.

Abstract
Background: Laparoscopic pancreaticoduodenectomy (LPD) is a difficult and complex surgical operation. Here, we review and analyze 199 cases of LPD performed at Henan University People’s Hospital and summarize the hospital team's experience.
Methods: Data related to 199 cases of LPD performed from January 1, 2017 to May 30, 2022 at the Henan University People's Hospital were collected and analyzed to define possible challenges and then used to propose potential solutions. The patients underwent operation using the “Kocher’s incision, caudal approach, and uncinate process first” approach for specimen removal followed by pancreaticojejunostomy using “Zhongyuan three-stitch method”.
Results: Our analysis showed that the average age of the patients was 58.4±11.1 years. The data showed that the operative time was 476.2 ± 95.9 minutes, intraoperative bleeding was 200 (200, 400) ml while intraoperative blood transfusion was 0 (0, 1200) ml. Further analysis showed that vascular resection and reconstruction was performed in 1 case (0.5%) for portal vein resection with end-to-end anastomosis. The duration of postoperative hospital stay was 17 (13, 24) days. A total of 71 (35.7%) cases had complications after surgery, 47 (23.6%) had pancreatic fistulas, including 19 (9.5%) grade A, 18 (9.0%) grade B, and 10 (5.0%) grade C fistulas while 30 (15.1%) were lost to follow-up. Ten (6.0%) cases experienced perioperative deaths, where a 1-, 3- and 5-year survival rate was 85.3%, 61.0% and 58.1%, respectively. Furthermore, our data demonstrated that the older the patient, the shorter the postoperative survival time (HR=1.049,95%CI 1.016~1.082，P=0.003) and the higher the CA199, the shorter the survival time (HR=1.000162,95%CI 1.000034~1.000290，P=0.013). Patients who underwent revascularization had a better survival rate (HR=0.117, 95%CI 0.015~0.866，P=0.038); adenocarcinoma of duodenum (74,37.2%), holangiocarcinoma (43,21.6%) and pancreatic cancer (29,14.6%) had significantly different long-term survival rates (c2=6.567,P=0.038).
Conclusions: Taken together, our analysis showed that although LPD is a complex and challenging technique, it is an effective and safe procedure as long as the operator solves the challenges during the procedure (such as the " Kocher’s incision, caudal approach, and uncinate process first " approach and the " Zhongyuan three-stitch method").

Abstract
Background
To increase retention in prevention of mother-to-child transmission programs, Mozambique launched a peer-support program in 2018, where HIV-positive mothers provide support as mentor mothers (MMs) by conducting home visits for HIV-positive pregnant and lactating women and HIV-exposed and infected children.
Methods
A qualitative evaluation was conducted across nine facilities in Gaza Province to assess the barriers, facilitators, and acceptability of the mentor mother program (MMP) among those receiving services and those providing services. In-depth interviews and focus group discussions were conducted with MMs, MM supervisors, health care workers (HCWs), HIV-positive mothers enrolled in the MMP, HIV-positive mothers who refused MMP enrollment, and key informants involved in the implementation of the program. Thematic content analysis identified emerging recurrent themes and patterns across the participants’ responses.
Results
The MMP was well received by HIV-positive women enrolled in the MMP, MMs providing services, and HCWs at the facilities. HIV-positive women reported that counseling from MMs improved their understanding of why anti-retroviral treatment (ART) adherence was important and how they should take their ART. HIV-positive mothers enrolled in the MMP reported having reduced guilt and shame about their HIV-status, feeling less alone, less isolated, and having more control over their health. MMs shared that their work made them feel valued and decreased their self-stigmatization. Additionally, MMs felt extremely satisfied having an impact on others’ lives. However, MMs also reported feeling that they had inadequate resources to perform job functions and listed inadequate transportation, insufficient stipends, and false address reports from HIV-positive mothers to the health facilities among their constraints. Overall, HCWs felt that their workload was significantly reduced with MM support and wanted more MMs in the community and health facility.
Conclusions
This study demonstrated that the MMP provided substantive and highly valued support to HIV-positive women, resulting in increased client understanding of ART’s purpose and administration as well as improved self-reported well-being and sense of community and reduced feelings of isolation. Recommendations include strengthening MM training and provision of resources, additional information provided to newly enrolled mothers and support for the male partners.
Research on Data Collision Avoidance Algorithm to Solve the Problem of LoRa Channel Resource Conflict in Loom Data Monitoring System
Authors: Xiao Yanjun , Li Yingjia , Tian Yu , Liu Weiling 
Published: March 2023

Abstract
LoRa is the key technology of Internet of Things wireless communication, LoRaWAN used ALOHA algorithm in the data conflict does not use conflict decomposition algorithm, the channel utilization is not high, and in the loom industry site, the number of looms is more, multiple LoRa terminal nodes need to report data to LoRa gateway nodes at the same time, the transmission frequency is relatively high, there is a possibility of heavy channel load. In view of the above problems, a communication mechanism based on the combination of time division multiple access and binary tree conflict decomposition algorithm is proposed, which can ensure that there is no data collision in static time slot terminal node communication, reduce node power consumption, and ensure that the terminal node that does not receive the receiving response frame uses a competitive way to report the data again, so that the packets participating in the collision can be successfully transmitted and the data integrity can be guaranteed. In order to prove the feasibility of this solution, this paper proposes a multi-loom data monitoring system scheme based on LoRa, and the actual tests show that the terminal node and gateway node can achieve 100% no packet loss within 400 m in the weaving machine industrial field environment, and the designed end node has low power consumption, which has certain reference value in loom data monitoring.

Published: March 2023

Abstract
Encephalopathy develops following sepsis, which is defined as life-threatening organ failure due to the irregular response of a host to infection. It has high mortality and morbidity rates. In this study, we aimed to investigate the effects of inflammation on brain tissue, and the effects of the gamma-aminobutyric acid-A (GABAA) receptor antagonist bicuculline in rats with sepsis. Sepsis was experimentally generated in rats using lipopolysaccharide (LPS). The rats were divided into four groups as control, LPS (10 mg/kg i.p.), bicuculline (1.5 mg/kg bicuculline methiodide s.c.), and LPS + bicuculline. Electrophysiologic recordings and body temperature measurements were completed at the 24th hour after injection, and blood samples were taken for measurements of biochemical parameters. TNF-α, IL-10, and GABA levels were measured using ELISA, and MDA levels were measured using the Bouge method. Tissue imaging was performed with S100-ß, NEUN, and synaptophysin antibodies using immunofluorescence staining. One-way ANOVA and the Tukey test were used in statistical analysis. Inflammatory parameters significantly increased in brain tissue in the LPS group compared with the other groups. The immunofluorescence staining results in brain tissues were as follows: S-100ß involvement increased, and NeuN and synaptophysin involvement decreased in the LPS group. In electrophysiologic recordings, activity consistent with acute non-focal seizures was observed in the LPS group; however, resting status was seen in the other groups. We suggest that bicuculline methiodide may be a prophylactic agent in sepsis, which causes impaired neurotransmitter balance, increased pro-inflammatory cytokines, lipid peroxidation, and decreased anti-inflammatory cytokine levels.
High abundances of microplastics in a tropical urban stream, negatively related to precipitation.
Authors: Ferreira Maria Gabriela Alves , Silva Jhonatan Barbosa da , Roche Kennedy Francis 
Published: March 2023

Abstract
Most studies on microplastic (MP) pollution in freshwaters consider large rivers and lakes, with streams relatively poorly studied. We analysed the temporal variation in abundance of MP particles in an urban stream draining commercial and residential areas, sampling on seven occasions during the course of nine months. We filtered samples through a nylon net of 68µm mesh size, carried out digestion with a novel method, namely WPO (H2O2 + Fe) followed by KOH, and analysed MP particles quantitatively and qualitatively by light microscopy. All samples contained MPs, with concentrations varying between 1.1 and 11.3 particles.L− 1. The most abundant forms were transparent filaments (found in 67% of the samples) and black fragments (found in 47% of the samples). MP concentrations were significantly positively related to the absence of rainfall. Mean transport was calculated to be 5.75x1011 items.year− 1. These abundances are equal or superior to those recorded in large rivers draining industrial areas, suggesting that small streams can be an important source of MP pollution.
Confidence Partitioning Sampling Filtering
Authors: Qiang Xingzi , XUE Rui , Zhu Yanbo 
Published: March 2023

Abstract
The confidence partitioning sampling filter (CPSF) method proposed in this paper is a novel approach for solving the generic nonlinear filtering problem. First, the confidence probability space (CPS) is defined, which restrict the state transition in a bounded and closed state space in the recursive Bayesian filtering. In the posterior CPS, the weighted grid samples, represented the posterior PDF, are obtained by using the partitioning sampling technique (PST). Each weighted grid sample is treated as an impulse function. The approximate expression of the posterior PDF, as key for the PST implementation, is obtained by using the properties of the impulse function in the integral operation. By executing the selection of the CPS and the PST step repeatedly, the CPSF framework is formed to achieve the approximation of the recursive Bayesian filtering. Second, the difficulty of the CPSF framework implementation lies in obtaining the real posterior CPS. Therefore, the space intersection (SI) method is suggested to obtain the approximate posterior CPS. On this basis, the SI_CPSF algorithm, as an executable algorithm, is formed to solve the generic nonlinear filtering problem. Third, the approximate error between the CPSF framework and the recursive Bayesian filter is analyzed theoretically. The consistency of the CPSF framework to the recursive Bayesian filter is proved. Finally, the performances of the SI_CPSF algorithm, including robustness, accuracy and efficiency, are evaluated using three representative simulation experiments. The simulation results showed that SI_CSPF requires far less samples than particle filter (PF) under the same accuracy. Its computation is on average one order of magnitude less than that of the PF. The robustness of the proposed algorithm is also evaluated in the simulations.
Thresholding Based Decision based Algorithm for the removal of Impulsive Artifacts in Images
Authors: kishorebabu vasanth , J Sridevi , Ch Raghava Prasad 
Published: March 2023

Abstract
A Novel modified trimmed Trimean filter method is suggested for the elimination of random and impulse noise as well as the clearing of various sorts of artefacts from the standard images. The suggested filter first divides the pixels into noisy and non-noisy categories before updating the noisy pixels with trimmed modified trimean and leaving the non-noisy pixels unmodified. On a Standard image database, exhaustive tests were run, and the performance of the suggested filter was assessed in terms of both quantitative and qualitative results using the current algorithm. The suggested method was discovered to have great noise suppression capabilities by maintaining the fine details of the image even at increasing noise densities.
Quality Monitoring for the Basic OxygenFurnace Steelmaking Process based on Nonlinear Filter
Authors: Song Dongying , Liu Chang , Song Xiangman 
Published: March 2023

Abstract
This paper addresses on the quality (the carbon content and the temperature of molten steel) monitoring problem for the basic oxygen furnace (BOF) steelmaking process. It can be realized by designing the filter for the system of BOF steelmaking process, which can be attributed to a class of discrete-time nonlinear systems with time delay and persistent bounded disturbances. To solve the design problem of nonlinear filter, the conditions of one-sided Lipschitz and quadratic inner-boundedness are introduced. The purpose of design is to efficiently attenuate the peak of estimation error caused by the disturbances. In order to solve the state estimation problem of the general system (the state transition matrix is stable) and the BOF steelmaking-like system (the state transition matrix is an identity one), Schur Complements and Finsler’s Lemma are introduced in the theoretical analysis, respectively. The algorithm stability and the sufficient conditions are derived to ensure the given performance, and the parameters of the filter algorithms are the solutions of linear matrix inequality (LMI). And the validity of the developed methods are verified by numerical examples, one of which is the BOF steelmaking numerical example, and the related results also have reference value for the actual production.
Lunar cycle drives family-specific larval fish assemblages in the tropical nearshore ecosystem
Authors: Ye Ali Md. , Yu Fatimah Md. , Ikhsan Natrah Fatin Mohd , Hassan Zafri 
Published: March 2023

Abstract
Responses to lunar cycles vary amongst taxonomically distinct marine creatures. We calculated larval fish diversity and density over four successive lunar phases: new, first quarter, third quarter, and full. A bongo net with a mesh size of 300µm mesh size from a tropical nearshore water of the Straits of Malacca, Malaysia. We collected 5,305 fish larvae from 27 different families. Diversity indices for richness (Shannon-Wiener, H), dominance (Simpson, D) and evenness (Pielou, E) decreased from the full lunar phase onwards. Larval density, on the other hand, was much higher during the new lunar phase. We also determined that the larval fish family was either selectively present during each lunar phase or had a peak density during full and new moons. The larval fish assemblages revealed a preference for spawning events during the lunar phases. Human activities in the vicinity area are advised to be minimised during this period to mitigate harmful influence on larval fish recruitment in the nearshore area.
Anti-EGFR Bioengineered Bacterial Outer Membrane Vesicles as Targeted Immunotherapy Agents in Triple-Negative Breast Tumor Murine Model

Published: March 2023

Abstract
Cancer immunotherapy using checkpoint inhibitors is considered a promising approach in various cancers, however, around 55–87% of patients fail to respond to this treatment. Combinatorial therapy through targeted nano-size particles carrying various Toll-like receptor (TLR) agonists to the tumor site can enhance the therapeutic index by activation of intratumoral antigen-presenting cell (APC). Outer membrane vesicles (OMVs) secreted by all gram-negative bacteria present various surface-exposed immune stimulators in their native conformation and Toll-like receptor activating components. In this study, OMVs were engineered to target highly overexpressing EGFR cancer cells in vitro. Affinity-based assays with both EGFR positive and negative cells were performed, and the equilibrium dissociation constant (Kd) of the designed scFv was calculated. Then, we employed the syngeneic model of a triple-negative mouse breast cancer, 4T1, to assess the function of bioengineered OMVs in vivo. Bioengineered OMVs were able to attach to EGFR high-expression cells in vitro. Analyzing the effectiveness of these nanovesicles in a triple-negative breast tumor mice model indicated that the administration route plays an important role in stimulating anti-tumor response. Both intraperitoneal (i.p.) and intratumoral (i.t.) injections of bioengineered OMVs stimulated innate immune response by activating natural killer cells and decreasing the rate of M2 macrophage in the tumor microenvironment. Contrary to the i.p. route with significant tumor size reduction, the in i.t. route only the growth of the tumor was inhibited. Considering both in vitro and in vivo results obtained in this study indicates the potential of OMVs as an effective anti-tumor strategy in future studies.
