Digital Cybernarrative: "The Brain Opera" by Todd Mahover
Authors: Bezmenov Vadim 
Published: August 2022

The article is devoted to the application of new technologies of the digital era in modern opera. The phenomenon of cybernarrative is analyzed, which creates special forms of representation of a conditional plot in an opera theater, or representation of the main idea. As a special form of cybernarrative, an analysis of the instrumentation and fundamental ideas of the Brain Opera by American composer and inventor Tod Mahover is proposed. This experimental composition combines both conceptual ideas of comprehending the basics of human thinking and attempts to present brain impulses as musical material that makes up the stochastic variable composition of the opera. Special attention is paid to interactivity, in which the listener pre–communicates with various interfaces - electronic toys that allow him to develop his creative energy and see it as an element of composition in the Opera of the Brain. The conclusion from the conducted research is that the idea of a cybernarrative has become fundamental for the project, which has received a cybernarrative representation. The treatise of the famous cognitive scientist Marvin Minsky "Community of the Mind" and the element of creative energy of the recipient – visitor of the sound installation serve as the basis of the narrative, while the plot of the libretto itself is conditional and it is hardly read through the journey through the so–called "wilds of the mind". Modern opera uses cybernarrative as a communication system, in the field of which all the latest technologies are included. At the same time, the content of the opera is blurred, which turns out to be variable. There are both positive and negative sides to this: the involvement of the public in the creative process, which Tod Mahover strongly encourages in his concept of the Brain Opera, helps to overcome passive perception, however, the composition ceases to be a complete form and turns into an open work – work in progress.

Published: August 2022

Background
Taekwondo is an intermittent Olympic combat sport, which shows an aerobic predominance in matches and high participation of alactic metabolism for actions that determine competitive success. However, there is no information on energetic contribution systems in different high-intensity intermittent exercises for metabolic conditioning with specific movements. The study aimed to measure the physiological demands, mainly the energy expenditure, in taekwondo-specific high-intensity intermittent exercises (HIIE).

Methods
This study recruited ten male black belt athletes with a mean age of 20.2 ± 4 years, body mass of 62.8 ± 10.5 kg and height of 170.6 ± 7.8 cm, and total practice time of 11.8 ± 5.4 years. Subjects performed an incremental specific test and three different HIIE protocols on nonconsecutive days, and all comprised three 2-min rounds and 1 min of recovery between rounds. Heart rate, oxygen consumption, and blood lactate were measured. Energetic expenditure of aerobic, alactic, and lactic metabolisms was estimated through oxygen consumption, excess post-exercise oxygen consumption, and peak blood lactate after each round.

Results
For the mean of the three rounds, the TKDtest100 resulted in higher absolute and relative contribution from the aerobic metabolism (52.4 ± 4%; p = 0.01) and lower than the 35:5 relative alactic contribution (48.7 ± 5.4%; p = 0.03).

Conclusion
The mean of the three rounds for 35:5 and 15:10:5 presented similar absolute and relative contributions of aerobic and alactic metabolisms, whereas the TKDtest100 was a predominantly aerobic activity. We emphasize that aerobic metabolism was predominant from the second round in the 15:10:5 and 100%TKDtest protocols and in the last round of the 35:5 protocol.

O trabalho apresenta uma síntese dos principais resultados da pesquisa A Reestruturação Produtiva e os impactos sobre o trabalho e o emprego bancário na Bahia, realizada no período 1998-2000, com o apoio do CNPq e do PIBIC/UFBa. A análise principal demonstra que as inovações tecnológicas - automação - e as mudanças organizacionais - terceirização e qualidade total em curso no setor bancário, ao lado de um processo de privatização dos bancos estatais, têm resultado numa situação de múltiplos riscos para os trabalhadores bancários. Esse quadro de intensa precarização do trabalho assume diferentes expressões: os bancários que ainda permanecem empregados vivem o risco de perder o emprego, a partir da s demissões em massa, que vêm ocorrendo desde o final dos anos 80; vivem o risco de se tornarem doentes ocupacionais, portadores de Lesões por Esforços Repetitivos, ou de adquirir problemas de saúde mental, como resultado da intensificação do trabalho e da automação; vivem o risco de sofrer assaltos e seqüestros e, portanto vivem arriscando as suas próprias vidas; e vivem um processo de "desencantamento" e de perda de identidade com o "ofício bancário", o que se tem refletido fortemente na atuação dos sindicatos, que vivem hoje correndo o risco de perder a sua representatividade e capacidade de luta e resistência.PALAVRAS-CHAVE: Trabalho, bancários, emprego, precarização, riscos. BANK EMPLOYEE: a multiple risk employment This paper summarizes the main results of the research the Productive Restructuring and its impacts on bank employment in Bahia, which carried out in the 1998-2000 period, with the support from CNPq and PIBIC/UFBa. The main analysis demonstrates that the technological innovations - automation - and the organizational changes - outsourcing and total qualities - that the bank sector is undergoing, toghter with the privatization process of the state banks, has led to a multiple risks situation for the bank employees. This picture of intense labor precarization adopts different expressions: the bank employees who still emain working in the banks run the risk of losing the job owing to the massive layoffs that have taken place since late 80s. They are subjects to occupational diseases, to repetitive effor lesions - REL - or mental health illnesses, beaceuse of labor intensification and automation. They are at danger of being robbed or kidnapped, and therefore they are constantly risking their own lives. They also experience the disenchantment process of loss of identity process with the "bank service", highly reflected through the unions movements, since their capacity of struggle and resistance is at stake.

ImportanceThe risk of venous thromboembolism (VTE) among patients with atopic dermatitis (AD), especially when receiving treatment with Janus kinase (JAK) inhibitors, is unclear.ObjectiveTo determine the association of AD with incident VTE and evaluate the risk of incident VTE among patients with AD who were receiving treatment with JAK inhibitors.Data SourcesThe MEDLINE, Embase, Cochrane Library, and Web of Science databases were searched with no restrictions on language nor geographic locations from their respective inception to February 5, 2022.Study SelectionCohort studies examining the association of AD with incident VTE and randomized clinical trials (RCTs) reporting VTE events in participants with AD receiving JAK inhibitors were included. Around 0.7% of initially identified articles met the selection criteria.Data Extraction and SynthesisThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. The risk of bias of included cohort studies and RCTs was assessed by the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool 2, respectively. A random-effects model meta-analysis was conducted to calculate the pooled hazard ratio (HR) and risk difference for incident VTE.Main Outcomes and MeasuresThe HRs for incident VTE associated with AD and risk difference for incident VTE between participants with AD who were receiving treatment with JAK inhibitors and controls receiving placebo or dupilumab.ResultsTwo cohort studies and 15 RCTs with a total of 466 993 participants were included. The meta-analysis found no significant association of AD with incident VTE (HR, 0.95; 95% CI 0.62-1.45; incidence rate of VTE, 0.23 events/100 patient-years). Overall, 3 of 5722 patients with AD (0.05%) who were receiving treatment with JAK inhibitors experienced VTE compared with 1 of 3065 patients with AD (0.03%) receiving placebo or dupilumab (Mantel-Haenszel risk difference, 0; 95% CI, 0-0). The incidence rate of VTE was 0.15 and 0.12 events per 100 patient-years in participants with AD receiving JAK inhibitors and placebo, respectively. The findings were similar in 4 unique JAK inhibitors (abrocitinib, baricitinib, upadacitinib, and SHR0302).Conclusions and RelevanceThe results of this systematic review and meta-analysis suggest that the currently available evidence does not detect an increased risk of VTE associated with AD or treatment with JAK inhibitors. These findings may provide a reference for clinicians in prescribing JAK inhibitors for patients with AD.

AbstractBackground and purposeThe lack of equitable access to radiotherapy (RA) linear accelerators (LINACs) is a substantial barrier to cancer care in low‐ and middle‐income countries (LMICs). These nations are expected to bear up to 75% of cancer‐related deaths globally by 2030. State‐of‐the‐art LINACs in LMICs experience major issues in terms of robustness, with mechanical and electrical breakdowns resulting in downtimes ranging from days to months. While existing research has identified the higher failure frequency and downtimes between LMICs (Nigeria, Botswana) compared to high‐income countries (HICs, the UK), there has been a need for additional data and study particularly relating to multileaf collimators (MLCs).Materials and methodsThis study presents for the first time the analysis of data gathered through a dedicated survey and workshop including participants from 14 Indonesian hospitals, representing a total of 19 LINACs. We show the pathways to failure of radiotherapy LINACs and frequency of breakdowns with a focus on the MLC subsystem.ResultsThis dataset shows that LINACs throughout Indonesia are out of operation for seven times longer than HICs, and the mean time between failures of a LINAC in Indonesia is 341.58 h or about 14 days. Furthermore, of the LINACs with an MLC fitted, % of all mechanical faults are due to the MLC, and % of cases requiring a replacement component are related to the MLC.ConclusionThese results highlight the pressing need to improve robustness of RT technology for use in LMICs, highlighting the MLC as a particularly problematic component. This work motivates a reassessment of the current generation of RT LINACs and demonstrates the need for dedicated efforts toward a future where cancer treatment technology is robust for use in all environments where it is needed.

AbstractBackgroundPlacing radioprotective devices near patients reduces stray radiation during percutaneous coronary intervention (PCI), a promising technique for treating coronary artery disease. Therefore, lead arm support may effectively reduce occupational radiation dose to cardiologists.PurposeWe aimed to estimate the reduction of stray radiation using a novel detachable lead arm support (DLAS) in PCI.Materials and methodsA dedicated cardiovascular angiography system was equipped with the conventional 0.5‐mm lead curtain suspended from the table side rail. The DLAS was developed using an L‐shaped acrylic board and detachable water‐resistant covers encasing the 0.5‐, 0.75‐, or 1.0‐mm lead. The DLAS was placed adjacent to a female anthropomorphic phantom lying on the examination tabletop at the patient entrance reference point. An ionization chamber survey meter was placed 100 cm away from the isocenter to emulate the cardiologist's position. Dose reduction using the L‐shaped acrylic board, DLAS, lead curtain, and their combination each was measured at five heights (80–160 cm in 20‐cm increments) when acquiring cardiac images of the patient phantom with 10 gantry angulations, typical for PCI.ResultsMedian dose reductions of stray radiation using the L‐shaped acrylic board were 9.0%, 8.8%, 12.4%, 12.3%, and 6.4% at 80‐, 100‐, 120‐, 140‐, and 160‐cm heights, respectively. Dose reduction using DLAS with a 0.5‐mm lead was almost identical to that using DLAS with 0.75‐ and 1.0‐mm leads; mean dose reductions using these three DLASs increased to 16.2%, 45.1%, 66.0%, 64.2%, and 43.0%, respectively. Similarly, dose reductions using the conventional lead curtain were 95.9%, 95.5%, 83.7%, 26.0%, and 19.6%, respectively. The combination of DLAS with 0.5‐mm lead and lead curtain could increase dose reductions to 96.0%, 95.8%, 93.8%, 71.1%, and 47.1%, respectively.ConclusionsDLAS reduces stray radiation at 120‐, 140‐, and 160‐cm heights, where the conventional lead curtain provides insufficient protection.
Model‐free adaptive control based on switching mechanism for multi‐input multi‐output wet flue gas desulfurization system

Published: August 2022

SummaryThe wet flue gas desulfurization (WFGD) process is a complex controlled system with nonlinear and time‐varying characteristics. There are a variety of external disturbances in the desulfurization process, which can easily cause a jump in system parameters and even structure. In response to this problem, a model‐free adaptive control scheme based on a switching mechanism is proposed, and the convergence analysis is given. In the scheme, firstly, the operating conditions of the WFGD system are divided into n kinds based on multiple external disturbances, and the mathematical models of the multi‐input multi‐output WFGD system under different operating conditions are established. Then the MFA controllers of the WFGD system under multiple operating conditions are established, respectively. Finally, a switching index function is designed to switch the controller of the WFGD system according to different operating conditions, so that the desulfurization system is always controlled by the most appropriate controller. In the simulation experiment, according to the actual data of the WFGD system of a 1000 MW coal‐fired power station in Beijing, the modeling test and algorithm simulation of the WFGD system under three operating conditions are carried out. The simulation results show that this method can effectively reduce the transient error of the WFGD system output and improve the desulfurization effect.

AbstractArtemisinin and its derivatives (artemisinins) are first‐line chemotherapeutic agents of lethal malaria, which also showed tremendous value in many other diseases including chronic inflammation. Unfortunately, almost all artemisinins are rapid‐acting medicines with an extremely short half‐life in vivo, which significantly limits their clinical application for these new adaptation diseases. In this study, a locally injectable long‐acting gene/artemisinin co‐delivery nano‐microplex consisting of a biodegradable hyaluronic acid (HA) microsphere and releasable gene/artemisinin co‐delivery nano‐lipoplex is developed first, to obtain an improved efficacy for rheumatoid arthritis (RA). Briefly, a cationic multicomponent drug‐embedded liposome with pharmacological activity is first reported based on two novel artemisinin derivatives (dAPC and dACC), which possess mimic phospholipids and cationic lipids, respectively. A cationic artemisinin‐embedded lipoplex is first reported as a medicative gene carrier here. An in situ injectable TNF‐α siRNA/artemisinin co‐delivery nano‐microplex (MTAsi@MG) is further prepared by immobilization of TNF‐α siRNA/lipoplex on porous microfluidic HA microspheres. Using this nano‐microplex for intra‐articular injection, the sustaining activity of gene therapy and artemisinin efficacy for RA long‐term treatment is first realized. Undoubtedly, this intra‐articular injectable TNF‐α siRNA/artemisinin co‐delivery nano‐microplex based on dAPC/dACC lipoplex and microfluidic microspheres would be one of the most potent gene/drug co‐delivery systems for RA therapy.

Published: August 2022

AbstractHigh‐power piezoelectric applications are predicted to share approximately one‐third of the lead‐free piezoelectric ceramic market in 2024 with alkaline niobates as the primary competitor. To suppress self‐heating in high‐power devices due to mechanical loss when driven by large electric fields, piezoelectric hardening to restrict domain wall motion is required. In the present work, highly effective piezoelectric hardening via coherent plate‐like precipitates in a model system of the (Li,Na)NbO3 (LNN) solid solution delivers a reduction in losses, quantified as an electromechanical quality factor, by a factor of ten. Various thermal aging schemes are demonstrated to control the average size, number density, and location of the precipitates. The established properties are correlated with a detailed determination of short‐ and long‐range atomic structure by X‐ray diffraction and pair distribution function analysis, respectively, as well as microstructure determined by transmission electron microscopy. The impact of microstructure with precipitates on both small‐ and large‐field properties is also established. These results pave the way to implement precipitate hardening in piezoelectric materials, analogous to precipitate hardening in metals, broadening their use cases in applications.

Published: August 2022

AbstractFerroelectric HfxZr1–xO2 (HZO) is typically achieved by crystallization of an amorphous thin film via rapid thermal processing (RTP) at time scales of seconds to minutes. For integration on III–V semiconductors, this approach can severely degrade the sensitive HZO/III–V interface. To evaluate whether a reduced thermal budget can improve the interface quality, millisecond duration thermal anneals are utilized using a flash lamp annealer (FLA) on HZO/InAs capacitors. Through thorough electrical characterization such as polarization hysteresis, endurance, and capacitance‐voltage measurements, as well as synchrotron‐based chemical interface characterization, the FLA and RTP treatments are compared and the FLA results are found in lower interface defect density and higher endurance, but also have generally lower remanent polarization (Pr) compared to RTP. Additionally, ways to achieve high Pr and low interface defect density using multiple lower energy flashes, as well as by pre‐crystallization during the ALD growth step are investigated. Using FLA, Pr exceeding 20 µC cm−2 is achieved, with extended endurance properties compared to RTP treatment and a considerably decreased defect density, indicative of a higher quality HZO/InAs interface. This work presents valuable insight into the successful integration of ferroelectric HZO on low thermal budget III–V semiconductors.

AbstractDespite the intensive efforts devoted to confining silicon (Si)‐based materials with heteromatrices for high‐energy‐density lithium‐ion batteries, addressing practical issues with rationally incorporated stereoactive matrix is still a significant challenge. This study presents an electrochemical‐active, metallic matrix for boosting Si‐based lithium‐ion storage. By employing a straightforward strategy involving mechanical ball‐milling and controllable phase transformation, spatially confined Si‐based composites enabled by metallic vanadium oxide (VO0.9) barriers can be readily achieved. The scalable interface engineering allows for expanded transportation channels and maintained structural integrity, which can be well established in both SiOx and Si cases. Endowed with promoted electron conduction as well as fast lithium‐ion diffusion, the optimal Si‐based composite electrodes demonstrate remarkable lithium storage performance, that is, an initial Coulombic efficiency of 81%, and a high specific capacity of 1249 mAh g−1 at 500 mA g−1 after 100 cycles. Notably, full cells coupled with a commercial LiCoO2 cathode are demonstrated, affording impressive specific energy of 440 Wh kg−1 at high mass loading. This work provides a cost‐effective approach to promoting the practical application of Si‐based anodes, which also holds promise for extension towards energy‐related applications and beyond.

AbstractPM6:Y6 is adopted as the active layer to prepare highly efficient organic photodetectors (OPDs), which is applied to realize a biometric sensor for real‐time heart‐rate monitoring. Here, the effects of the device structure, thickness, deposition process, and solvent on the subsequent performance of the OPDs are examined. Through judicious choice of the fabrication conditions, an OPD is obtained displaying a dark current density of less than 8.77 × 10−10 A cm−2, a responsivity of greater than 0.516 A W−1, and a high detectivity of 3.1 × 1013 Jones, measured at bias of −2 V (870 nm). This OPD featured a wide linear dynamic range (LDR, 530 nm) of 104 dB at −2 V, an ultrahigh cutoff frequency (750 kHz) and rise/fall times of less than 220 ns under a reverse bias of −2 V. This sub‐microsecond response and high detectivity is comparable with, and in some cases better than, those of the state‐of‐the‐art perovskite‐PDs and Si‐PDs. The OPD displays consistent responses, good repeatability, and stability [ambient: 50% humidity, 25 °C)]. The air‐stable and portable OPD‐based photoplethysmogram system provides clear signal resolution, potentially benefitting its applicability to blood pressure monitoring.
