Alloimmune responses in kidney transplant (KT) patients previously hospitalized with COVID-19 are understudied. We analyzed a cohort of 112 kidney transplant recipients who were hospitalized following a positive SARS-CoV-2 test result during the first 20 months of the COVID-19 pandemic. We found a cumulative incidence of 17% for the development of new donor-specific antibodies (DSA) or increased levels of pre-existing DSA in hospitalized SARS-CoV-2-infected KT patients. This risk extended 8 months post-infection. These changes in DSA status were associated with late allograft dysfunction. Risk factors for new or increased DSA responses in this KT patient cohort included the presence of circulating DSA pre-COVID-19 diagnosis and time post-transplantation. COVID-19 vaccination prior to infection and remdesivir administration during infection were each associated with decreased likelihood of developing a new or increased DSA response. These data show that new or enhanced DSA responses frequently occur among KT patients requiring admission with COVID-19 and suggest that surveillance, vaccination, and antiviral therapies may be important tools to prevent alloimmunity in these individuals.
Commodity and Equity Markets: Volatility and Return Spillovers
Authors: Pinho Carlos , Maldonado Isabel
Published: July 2022

The present paper provides an empirical analysis of the relationship between shocks to commodity markets and stock markets. By employing a total volatility connectedness measure, we study the relationship between shocks to oil, gold, copper, and agricultural commodity markets and emerging and developed stock markets. We conduct a connectivity analysis in the time and frequency domain to quantify market linkages using volatility spillovers over the period from 2004 to 2021. In addition, we analyze the spillovers of returns in these markets over the same period. The results suggest that both on volatility and returns spillovers, slightly more than 35% of the total variance of forecast errors is explained by shocks to markets during the period January 2004 to June 2021. We also show that, in terms of both volatility and returns, the contribution of equity market shocks to other markets is substantially more important than that of commodities; however, our analysis reveals that the total link between market returns is larger in the short run than in the long run, while in the case of volatility, the long-run frequencies concentrate the market link. Additionally, we use dynamic analysis to assess both the time evolution of total connectivity and all directional partial connectivity between markets. Our results show that both volatility and return linkages change significantly over time and that a set of events has a significant impact on them.
Magnetic Vortex Core String Gyrotropic Oscillations in Thick Cylindrical Dots
Authors: Guslienko Konstantin
Published: July 2022

The nonuniform magnetic vortex gyrotropic oscillations along the cylindrical dot thickness were calculated. A generalized Thiele equation was used for describing the vortex core motion including magnetostatic and exchange forces. The magnetostatic interaction was accounted for in a local form. This allowed reducing the Thiele equation of motion to the Schrödinger differential equation and analytically determining the spin eigenmode spatial profiles and eigenfrequencies using the Liouville–Green method for the high-frequency modes. The mapping of the Schrödinger equation to the Mathieu equation was used for the low-frequency gyrotropic mode. The lowest-frequency gyrotropic mode transformed to the dot faces localized mode, increasing the dot thickness. The vortex gyrotropic modes are described for a wide range of the dot thicknesses according to the concept of the turning points in the magnetostatic potential. This approach allows treating the vortex localized modes (turning points) and nonlocalized modes within a unified picture.

Published: July 2022

The separation of chemical components from wild plants to develop new pesticides is a hot topic in current research. To evaluate the antimicrobial effects of metabolites of Ligusticum chuanxiong (CX), we systematically studied the antimicrobial activity of extracts of CX, and the active compounds were isolated, purified and structurally identified. The results of toxicity measurement showed that the extracts of CX had good biological activities against Botrytis cinerea, Sclerotinia sclerotiorum, Alternaria alternata and Pythium aphanidermatum, and the value of EC50 were 130.95, 242.36, 332.73 and 307.29 mg/L, respectively. The results of in vivo determination showed that under the concentration of 1000 mg/L, the control effect of CX extract on Blumeria graminis was more than 40%, and the control effect on Botrytis cinerea was 100%. The antifungal active components of CX were identified as Senkyunolide A and Ligustilide by mass spectrometry and nuclear magnetic resonance. The MIC (minimum inhibitory concentration) value of Senkyunolide A and Ligustilide against Fusarium graminearum were 7.81 and 62.25 mg/L, respectively. As a new botanical fungicide with a brightly exploitative prospect, CX extract has potential research value in the prevention and control of plant diseases.
Microfluidic Nanomaterial Synthesis and In Situ SAXS, WAXS, or SANS Characterization: Manipulation of Size Characteristics and Online Elucidation of Dynamic Structural Transitions
Authors: Yaghmur Anan , Hamad Islam
Published: July 2022

With the ability to cross biological barriers, encapsulate and efficiently deliver drugs and nucleic acid therapeutics, and protect the loaded cargos from degradation, different soft polymer and lipid nanoparticles (including liposomes, cubosomes, and hexosomes) have received considerable interest in the last three decades as versatile platforms for drug delivery applications and for the design of vaccines. Hard nanocrystals (including gold nanoparticles and quantum dots) are also attractive for use in various biomedical applications. Here, microfluidics provides unique opportunities for the continuous synthesis of these hard and soft nanomaterials with controllable shapes and sizes, and their in situ characterization through manipulation of the flow conditions and coupling to synchrotron small-angle X-ray (SAXS), wide-angle scattering (WAXS), or neutron (SANS) scattering techniques, respectively. Two-dimensional (2D) and three-dimensional (3D) microfluidic devices are attractive not only for the continuous production of monodispersed nanomaterials, but also for improving our understanding of the involved nucleation and growth mechanisms during the formation of hard nanocrystals under confined geometry conditions. They allow further gaining insight into the involved dynamic structural transitions, mechanisms, and kinetics during the generation of self-assembled nanostructures (including drug nanocarriers) at different reaction times (ranging from fractions of seconds to minutes). This review provides an overview of recently developed 2D and 3D microfluidic platforms for the continuous production of nanomaterials, and their simultaneous use in in situ characterization investigations through coupling to nanostructural characterization techniques (e.g., SAXS, WAXS, and SANS).

This paper summarizes the basic characteristics of the cultural landscape in historical blocks by combing the relevant research results from visual evaluation of the landscape in historical blocks. Nine streets and alleys in the five historical blocks of Quanzhou, Fujian, were selected as the research objects, and the current situations of cultural landscapes in their spaces were collected and drawn into a table. The Semantic Differential (SD) method and Factor Analysis (FA) method were used to investigate and visually evaluate nine streets and alleys in five historical and cultural blocks in Quanzhou City. The questionnaire was formed in accordance with the requirements of the SD method, and evaluation was performed according to the questionnaire data. The FA method was used to further analyze the data, deduce the landscape evaluation curve and comprehensive evaluation table of historical and cultural blocks and construct the landscape visual evaluation system for blocks. At the same time, combined with the weight of each factor, the comprehensive evaluation score of each block was calculated. Finally, according to the score, the nine historical and cultural streets are sorted, the reasons are analyzed, and the references are discussed to provide scientific reference for the development and evaluation of other historical blocks.

Authors: Bie Fengfeng , Guo Yue , Gu Sheng , Yang Gang , Pang Mingjun
Published: July 2022

Accurate buried pipeline state recognition based on acoustic signal is a difficult and important issue. This paper proposes a feature extraction method based on acoustic signal frame and principal component analysis (PCA) for condition monitoring in pipes. This method makes use of the
property of nonstationary and multivariate data decomposition scales of pipeline acoustic signal. Signal framing is processed on the collected acoustic signals so that the signal frame series is obtained. Then, the sound pressure level of each frame signal is extracted, and the feature vector
of the total sound pressure level is established. The PCA method is applied to optimize the extracted feature vector set for detecting the feature parameters. The acoustic signals related to different operating conditions of a pipeline are identified with the support vector machine. Research
on a series of experiments shows that the proposed method for acoustic signal analysis can perform effectively for robust feature extraction and pipeline state identification.
Underwater shipping noise impacts to marine life: a global issue
Authors: Bahtiarian Michael
Published: July 2022

Underwater noise from shipping and its impact on marine life has been addressed by numerous governments and non-governmental organizations since the early part of the twenty-first century. The issue has reached the highest level of shipping regulation, the International Marine Organization
or IMO, a sub-organization to the United Nations. Since the 1990's, marine biologists have known that the increase in underwater-radiated noise has multiple negative impacts on various species of marine life and each species has different impacts with different acoustic thresholds. At regulatory
levels, it is believed that the problem can be solved by reducing underwater radiated noise from all vessels; shipping noise. However, there is no simple solution. It requires a cross-functional team including marine-biologists, underwater acousticians, vessel owners/operators, and naval architects/ship
designers. Solutions will only occur with efforts directed at the highest governmental and inter-governmental levels. Topics that are being addressed include impacts on marine life, underwater noise limits, operational restrictions on shipping, shipboard noise mitigation, and methods of underwater
sound prediction and measurement.

The United States Department of the Navy (Navy), as directed by Congress, executed a real time sound monitoring study of jet aircraft at Naval Air Station (NAS) Whidbey Island and NAS Lemoore over the past year and compared the resulting measured data with modeled noise data. The Navy
collected real-time aircraft sound level and operational data during four discrete seven-day monitoring periods in 2020 and 2021. The data collected each period included: (1) acoustic recordings by sound level meters deployed at sites around each airfield to capture sound levels during a range
of flight operations across a range of seasonal weather conditions; and (2) detailed operations data. The collected acoustic data are compared to noise modeling done specifically for this study using the observed flight operations data. This presentation provides and overview of the measured
data and the results of the comparison with modeled data.
Solid safety barriers as a highway traffic noise reduction strategy
Authors: Cubick Karel , Rochat Judith
Published: July 2022

Placing solid safety barriers (concrete crash barriers) along a highway, instead of steel guard rail, can help reduce traffic generated noise at nearby sensitive sites. The effectiveness of these barriers on traffic noise levels is dependent on the height of the barrier, the number
of traffic lanes, vehicle mix, and the elevation of the receiver relative to the barrier. The effect of solid safety barriers for sites at a variety of distances from a highway has been investigated for both city streets and freeways of various widths using the U.S. Federal Highway Administration
Traffic Noise Model (TNM). TNM predicted noise level reductions, attributable to solid safety barriers, were developed for research scenarios in locations with both hard soil and lawn ground types. Results show a readily perceptible and sometimes substantial noise reduction at sites within
a few hundred feet of the roadway.
METHODOLOGICAL SUPPORT FOR THE ASSESSMENT OF SUSTAINABLE DEVELOPMENT OF FOREST COMPLEX ENTERPRISES FOR STRATEGIC PLANNING PURPOSES
Authors: Zinoveva Irina , Burmistrov A.
Published: July 2022

Strategic planning of sustainable development of enterprises is becoming a widely demanded practice both in management activities and in scientific research. This is the process of developing, adjusting and implementing a strategy that represents a specific goal and a mechanism for achieving this goal. It is impossible to imagine building up the strategic potential of an industrial enterprise without sustainable development within the framework of the set strategic goals. This circumstance is characteristic of the current stage of development of the industrial economy, when the activity of the enterprise should be aimed at optimizing and maintaining the economic, social and environmental spheres of its functioning, in order to create favorable conditions for achieving business goals. According to various studies, Russian enterprises, especially enterprises of the timber industry, are still lagging behind Western ones in organizing the process of sustainable development. This process, in addition to the development and implementation of mechanisms for the functioning of enterprises, involves the assessment of sustainable development. The article considers the approach proposed by the authors to assessing the sustainable development of enterprises of the forest complex for strategic planning purposes (using the example of enterprises of the Voronezh region), which involves an integrative analysis expressed in a graphical positioning model.

Cultural Update of ‘Mullaippaattu’
Authors: A Vasanthi
Published: July 2022

Listening to good omens was a custom of that time. It means hearing good words. There is faith in this, even in this age. The woman regretted the separation of her man. Elderly women asked ‘Good Omen’ to find out if the man would come soon to console their woman. They sprinkled rice and flowers and worshipped the god in the evening. At that time, one of the shepherdesses said to the calf that was grieving for parting with the mother cow, ‘Soon mother comes’ and hoped that the departed man would return soon. They told the woman this good news and blessed her. There was an employee who was called Time Clerk to keep track of the time. Those who calculate the time correctly with the help of a tool called Hour disk are called as Time clerks. It is said that there was a time clerk in the ‘Mullaipp Paattu’ army camp. There were maids to light the lamps in palaces and army camps. These women wore bandeaus. Their hands were adorned with bangles. These women were the wielders of the luminous sword that could turn night into day. They were heroic women. They were body guards for the King. They will wrap themselves in cloth. There were strict Yavanars, who wore shirts, in the palace jobs. The Yavanas are people from Greece and Rome. Thus, it is possible to understand the relationship Tamil Nadu had with those countries during the Sangam period. Mullaipattu says that the Mlecchas who could not speak were also on duty for the King. Such non-verbal people supported the king in keeping secrets. The account of Mullaipattu gives a clear picture of the manner in which the army camps were set up on the battlefields. Separate accommodations were set up for the king and separate rooms for other soldiers. The king's accommodation consisted of many rooms. People wore ornaments like shell bangles, and small bangles. We understand that the musical instrument "harp" and the hour-measuring instrument "Time" were used. Musical instruments like the harp and arched harp were played when the king's armies returned victorious.
The Norman Coinage of Roger I the Great Count

Published: July 2022

Статья знакомит читателя с одним из самых интересных памятников нумизматики средневековой Европы - монетой, отчеканенной от имени графа Рожера Боссо (1031–1101), первого норманнского правителя Сицилии. Уникальная иконография трифолларо Рожера I привлекала не одно поколение нумизматов-исследователей, но до сих пор многие тайны чеканки этой монеты остаются неразгаданными. Автор пытается найти истоки оригинальной композиции оформления трифолларо, проследить норманнское влияние на выбор сюжета монеты, исследует метрологию рассматриваемой эмиссии и связь с нумизматикой и сфрагистикой франков в Леванте. Автор приходит к выводу о прочтении программы оформления аверса и реверса трифолларо Рожера, как пропаганды власти норманнского правящего класса в Сицилии и прославления графа Рожера — покровителя и защитника Церкви и христианства.

The article introduces the reader to one of the most fascinating numismatic monuments of Medieval Europe — the coin, minted by the Count Roger Bosso (1031–1101), the first Norman ruler of Sicily. The unique iconography of Roger’s trifollaro continues to intrigue generations of numismatists (both collectors and researchers). Many of the coin’s secrets remain resolved. In the article, the author tries to find the roots of the original composition that decorates the trifollaro, to trace the Norman influence on the selection of the imagery, studies the metrology of the given emission, and the coin’s connection to the numismatics and sigillography of the Franks in the Levant. The author comes to the conclusion that the goal of the program imagery on the obverse and reverse of Roger’s trifollaro is the propaganda of the Norman ruling class in Sicily and the glorification of Count Roger as the patron and defender of the Church and Christianity.

Published: July 2022

Oil palm empty fruit bunches (OPEFB) are waste products from the oil palm plantations, which is still an issue in Indonesian plantations. The high cellulose content in OPEFB enables them to be processed into cellulose nanofibers (CNF) that can be applied as fillers in the hydrogel. This research aimed to synthesize cellulose-based superabsorbent hydrogel and observe the optimal condition to produce hydrogel with high absorption and good thermal properties. CNF-based hydrogel is an excellent option to improve the physicochemical characteristics of the hydrogel. In this work, carboxy methyl cellulose hydrogel was firstly prepared by using citric acid. Then, CNF were added as fillers at different ratio variations, such as 0, 1, 3, 5, and 7 wt%. The surface morphology of the hydrogel showed rough surfaces, except for the 7 wt% CNF variation that produced hydrogel with a homogeneous surface. The cross-linking between the hydrogel and the fillers was evaluated by Fourier-Transform Infrared Spectroscopy (FTIR). A peak associated with the carboxylic acid functional group indicated hydrogel formation. The incorporation of CNF did not change the FTIR spectra since both materials had similar structures. Water absorption analysis showed that the developed product could be classified as a superabsorbent since all samples showed a degree of swelling above 200 g.g−1. CNF content at a 1 %wt ratio had the highest water retention and best thermal stability. The hydrogel showed exceptional characteristics, being suitable for various applications, mainly in agricultural sectors that required water delivery to the soil.
CAN POOR ADAPT TO THEIR CONDITIONS (EMPIRICAL STUDY FROM INDONESIA)
Authors: Subanti Sri , Pratiwi Hasih , Riani Asri Laksmi , Hakim Arif Rahman
Published: July 2022

This study aims to answer whether the poor in Indonesia can adapt to poverty. The fundamental approach of this research is constructed from the concept of aspiration. This study uses national socio-economic survey data and applies panel data analysis techniques. The research novelty will be useful for increasing interest in poverty adaptation studies, providing empirical evidence with developing country contexts, and encouraging pro-poor policies. Our findings show that increasing individual income and reference group income can increase aspirations to survive and live a normal life in their version. The gap between aspirations and reality still exists for those who fall into the poor category. However, they can still carry out an 'adaptation process,' with the income felt by an individual at the minimum to adjust to the current needs. This indicates that they strive to realize their aspirations to survive and continue to live life to the best of their ability. Furthermore, poverty adaptation differs across demographic groups and socio-economic backgrounds. Therefore, some people with this condition may react differently to poverty. The study's findings are important for informing poverty-reduction and poverty-alleviation policies. However, the government should not implement poverty adaptation directly because the government must still intervene in the form of policy and program synergies to reduce the poor and improve the welfare of the poor.

Published: July 2022

Forest resources will suffer damage and sustainability if they are used excessively. The characteristics of common-pool resources (CPRs) are forms of natural resources that involve many people so that they are vulnerable to damage due to the inability of the owner or manager to restrict other parties from taking part in utilizing them (non-excludable/non-trivial), and the use made by one party will reduce the benefits for the other party (subtractable). The actors in the network have made a good contribution in solving the challenges of the tasks and functions of the FMU in implementing community empowerment policies so that FMU development programs can be accepted by all stakeholders interests, especially local leaders, business people, relevant technical agencies, community leaders, non-governmental organizations, and village communities as beneficiaries. This research is qualitative-verificative with a case study approach that aims to understand the empirical phenomenon of the implementation process of forest community-based forest management policies. Stakeholder data was collected in implementing community empowerment policies in the Yogyakarta Model KPHP stakeholders. This qualitative analysis is historical-comparative, based on historical chronology with inductive and generative methods. The recommended empirical model analyzes the role of leadership in the FMU and the influence of the symbolic figure (Ngarso Dalem) in forming a network of actors and successfully implementing community empowerment policies in the Yogyakarta Model KPHP. Stakeholders must collaborate to solve the challenges of working on FMUs so that FMU development programs can be accepted by all stakeholders, especially local leaders, business people, relevant technical agencies, community leaders, Non-Governmental Organizations, and the community itself as beneficiaries.
OPERATIONAL MATRIX OF GENERALIZED BLOCK PULSE FUNCTIONS FOR SOLVING FRACTIONAL VOLTERRA–FREDHOLM INTEGRO-DIFFERENTIAL EQUATIONS
Authors: Mohammedfaeq Shabaz Jalil , Ahmed Shazad Shawki
Published: July 2022

This article aims to introduce two effective numerical approaches for solving the mixed linear fractional Volterra-Fredholm integro-differential equation (FVIDE) and multi-higher order with initial conditions. Even though these approaches transfer the integro-differential equations into a system of algebraic equations through operational matrices of generalized block pulse functions, these problems can be transferred to a system of algebraic equations by expanding the solution's multi-highest order derivative through the block pulse functions (BPFs). The block pulse operational matrices for fractional-order integration are derived by expanding the Riemann-Liouville fractional integral for repeated fractional integration in block pulse functions (BPFs). Also, the fractional derivative is done by using the generalized operational matrices of BPFs with the fractional calculus properties in the first scheme. The methods are attractive in the calculation, and examples are supplied to explain their use. The estimated and exact outcomes are compared in a table. In addition, they decrease the error terms in the specified domain using the least squares-error technique. For this, most general programs are written in Python V.3.8.8 software (2021).

Published: July 2022

Ternate Basin is located a small volcanic island in the archipelago of North Maluku, Indonesia. This island has very limited water resources and prone to seawater intrusion. This study aims to determine and analyze the distribution of hydrogeological interest points, determine patterns and directions of groundwater flow, and analyze hydrogeochemical quality and groundwater facies. Determination of the free aquifer zone was carried out by geoelectric measurements in 37 points, while the interpretation of confined aquifers was carried out in 17 drill log points. The quality of groundwater was analyzed in the study area, 126 samples were collected and analyzed. The piper diagram was adopted to identify groundwater facies. The determination of groundwater basin with a total recharge of 54,155 million m3/year. The saturated zone of groundwater flow reaches 1.237 million m3/day or 451.712 million m3/year. The quality of groundwater laboratory results indicates that the water from the two aquifer sources is suitable as a source of drinking water with moderate permeability and has met the quality standards. There were three groundwater facies in the study sites consisting of calcium magnesium bicarbonate (C4H4-Ca-MgO12), calcium magnesium chloride (CaCl2-MgCl2) and sodium potassium chloride (NaCL-KCL). Bicarbonate facies type in the groundwater basin indicated localized flow systems. This means the groundwater in the study site has a recharge area close to its groundwater source. Meanwhile, chloride facies type in the groundwater basin indicates a long process of flow pattern and allows the groundwater to interact with seawater or magmatic matters. These results can be used for policymakers to determine the appropriate and accurate location for groundwater exploitation for the public purposes. Determination of the location must be carried out by considering the flow, quantity, and quality of groundwater.

Published: July 2022

We study the spin-valley-dependent transport and magnetoresistance (MR) effect in a ferromagnetic MoS2 junction modulated by the off-resonance circularly polarized light (CPL). It is found that the conductance could be 100% spin- and valley-polarized simultaneously in the P configuration. Perfect valley polarization can also be realized in the AP configuration. The spin polarization presents an oscillating behavior in AP configuration due to the spin–orbit coupling. Furthermore, the junction achieves a high magnetoresistance that can be controlled by the exchange field and the light.

The author’s view
The extent to which an English judge, in the absence of hearing a foreign expert, can take into account foreign law and the stage that foreign proceedings have reached is greater than generally understood.

La misura in cui un giudice inglese, in assenza dell’audizione di un esperto straniero, può prendere in considerazione il diritto straniero e il livello raggiunto dai procedimenti stranieri è superiore a quanto generalmente condiviso.
Il negozio fiduciario tra società fiduciaria autorizzata e fiduciante ha rilevanza fiscale e non può essere qualificato come fittizio
Authors: Accinni Alessandro , Arienti Leonardo
Published: July 2022

Tesi
Il contratto di amministrazione fiduciaria con intestazione di beni conferito ad una società fiduciaria operante ai sensi della L. 23 novembre 1939, n. 1966, pur costituendo interposizione reale, determina la conservazione in capo al fiduciante della effettiva proprietà del bene fiduciariamente intestato. Ne consegue la rilevanza fiscale del rapporto per cui il solo fiduciante riveste l’identità di soggetto passivo di imposta ed è, dunque, l’unico possibile destinatario della pretesa erariale. 
 
The author’s view
The fiduciary administration agreement with fiduciary registration of assets conferred to a fiduciary company i.e. «fiduciaria» operating under Law No. 1966 of November 23, 1939 although leading to a real interposition of person, determines the preservation in the hands of the «fiduciante» of the actual ownership of the assets. It follows that the tax relevance of the relationship is such that the «fiduciante» itself is the effective taxable entity and it is, therefore, the only possible person subject to the tax claim.

The heart sound signal captured via a digital stethoscope is often corrupted with environmental and physiological noise, altering its salient and critical properties. The problem is exacerbated in crowded low-resource hospital settings with high noise levels. In this study, inspired by the heart sound’s quasi-periodic nature, we present a novel deep encoder-decoder based LU-Net architecture to suppress ambient hospital and internal lung sound noises that corrupt the heart sounds. Training is done using a large benchmark PCG dataset mixed with physiological noise, i.e., breathing sounds. Two different noisy datasets were created for experimental evaluation by mixing unseen lung sounds and hospital ambiance noises with the clean heart sound recordings. We also use the inherently noisy portion of the PASCAL heart sound dataset for evaluation. Experimental results show that the proposed framework can effectively suppress background noise in both real-world and synthetically generated noisy heart sound recordings, improving the signal-to-noise ratio (SNR) level by 5.575 dB on an average using only 1.32 M parameters. The study reveals that the proposed model outperforms the current state-of-the-art U-Net model with an average SNR improvement of 5.613 dB and 5.537 dB in the presence of lung sound and hospital noise, respectively. LU-Net also outperformed the state-of-the-art Fully Convolutional Network (FCN) by 1.750 dB and 1.748 dB for lung sound and hospital noise conditions, respectively. In addition, the proposed denoising method model improves classification accuracy by 38.93% in the noisy portion of the PASCAL heart sound dataset. The proposed enhancement scheme can thus play a vital role in deploying automated cardiac screening systems in low-resource and underserved communities.

Stable and accurate electroencephalogram (EEG) signal acquisition is fundamental in non-invasive brain-computer interface (BCI) technology. Commonly used EEG acquisition system’s hardware and software are usually closed-source. Its inability to flexible expansion and secondary development is a major obstacle to real-time BCI research. This paper presents the Beijing University of Posts and Telecommunications EEG Acquisition Tool System named BEATS. It implements a comprehensive system from hardware to software, composed of the analog front-end, microprocessor, and software platform. BEATS is capable of collecting 32-channel EEG signals at a guaranteed sampling rate of 4k Hz with wireless transmission. Compared to state-of-the-art systems used in many EEG fields, it displays a better sampling rate. Using techniques including direct memory access, first in first out, and timer, the precision and stability of the acquisition are ensured at the microsecond level. An evaluation is conducted during 24 hours of continuous acquisitions. The data loss is 0 packets and the average maximum delay is only 0.07 s/h. Moreover, as an open source system, BEATS provides detailed design files, and adopts a plug-in structure and easy-to-access materials, which makes it can be quickly reproduced. Schematics, source code, and other materials of BEATS are available at https://github.com/buptantEEG/BEATS. 
Validation of electric vehicle battery capacity measurements with on-board charger

Published: July 2022

Battery degradation is a main concern for electric vehicle (EV) users and a reliable capacity estimation is of major importance. Every EV battery management system (BMS) provides a variety of information, including measured current and voltage, and estimated capacity of the battery. However, the estimations are subject to the car manufacturer methodology and the measurement accuracy is unknown. This article uses extensive measurements from six diverse EVs to compare and assess capacity estimation with three different methods: (1) reading the capacity estimation from the BMS through the central area network (CAN) bus, (2) using an empirical method with external current measurements and (3) using the same empirical method with measurements coming from the BMS. The empirical method relies on a full discharge and charge cycle and measuring the total current flowing into the battery. We show that the use of BMS current measurements provides consistent capacity estimation (a difference of approximately one percent) and can circumvent the need for costly experimental equipment and DC chargers. This data can simplify the empirical method by only using an on-board diagnostics port (OBDII) reader and an AC charger, as the car measures the current directly at the battery terminals. We compare the capacity based on the current measurements with the internal BMS estimation of the capacity, and provide insight on how that can be interpreted.
