Kernel based model parametrization and adaptation with applications to battery management systems

Kernel Based Model Parametrization and Adaptation with Applications to Battery Management Systems by Caihao Weng Co-Chairs: Jing Sun and Huei Peng With the wide spread use of energy storage systems, battery state of health (SOH) monitoring has become one of the most crucial challenges in power and energy research, as SOH significantly affects the performance and life cycle of batteries as well as the systems they are interacting with. Identifying the SOH and adapting of the battery energy/power management system accordingly are thus two important challenges for applications such as electric vehicles, smart buildings and hybrid power systems. This dissertation focuses on the identification of lithium ion battery capacity fading, and proposes an on-board implementable model parametrization and adaptation framework for SOH monitoring. Both parametric and non-parametric approaches that are based on kernel functions are explored for the modeling of battery charging data and aging signature extraction. A unified parametric open circuit voltage model is first developed to improve the accuracy of battery state estimation. Several analytical and numerical methods are then investigated for the non-parametric modeling of battery data, among which the support vector regression (SVR) algorithm is shown
Immobilization of cellulase for large scale reactors to reduce cellulosic ethanol cost

Cellulosic ethanol is an alternative renewable energy source. Cellulase used in the production of cellulosic ethanol is very expensive. The difficulty in separating cellulase from the cellulose solution after the hydrolysis process limits the reusability of the cellulase, which highly precludes the scales of this application because of the high cost of the enzyme. Immobilization of cellulase provides a promising approach to allow the enzyme to be recycled, thus reducing the production cost. This research focused on immobilizing cellulase for reuse to reduce the cellulosic ethanol cost. Four immobilization techniques were explored for the immobilization of cellulase on four different immobilization carriers. The immobilized cellulases by Layer-by-Layer Nano-Assembly (LbL) and Ca2+-Al(OH)x modification methods had high initial activities but low reusabilities. Enzyme desorption was observed during the hydrolysis of cellulose solutions by the immobilized cellulases for both LbL and Ca2+-Al(OH)x modification methods. Efforts were focused on improving the reusability of the immobilized cellulase, yet rarely worked. For the immobilized cellulase by the combination of Ca2+-Al(OH)x modification and LbL, the reusability of the immobilized cellulase was improved with the number of enzyme layers. Unfortunately, for the present moment, the initial activity decreased with the number of enzyme layers. Immobilization of cellulase on silica gel by 3-APTES and glutaraldehyde modification showed the highest reusability. No enzyme desorption was observed during the hydrolysis of cellulose solution. It indicated that the cellulase molecules firmly covalent bound to the silica gel. The immobilized cellulase on silica gel by 3-APTES and glutaraldehyde modification had the highest activity per unit mass of immobilization carriers because of the porous structure of the silica gel.
Josephson parametric converter saturation and higher order effects

Microwave parametric amplifiers based on Josephson junctions have become indispensable components of many quantum information experiments. One key limitation which has not been well predicted by theory is the gain saturation behavior which limits the amplifier's ability to process large amplitude signals. The typical explanation for this behavior in phase-preserving amplifiers based on three-wave mixing, such as the Josephson Parametric Converter, is pump depletion, in which the consumption of pump photons to produce amplification results in a reduction in gain. However, in this work, we present experimental data and theoretical calculations showing that the fourth-order Kerr nonlinearities inherent in Josephson junctions are the dominant factor. The Kerr-based theory has the unusual property of causing saturation to both lower and higher gains, depending on bias conditions. This work presents an efficient methodology for optimizing device performance in the presence of Kerr nonlinearities while retaining.
Aperiodic electrophysiological activity in preterm infants is linked to subsequent autism risk.

Approximately 7% of preterm infants receive an autism spectrum disorder (ASD) diagnosis. Yet, there is a significant gap in the literature in identifying prospective markers of neurodevelopmental risk in preterm infants. The present study examined two electroencephalography (EEG) parameters during infancy, absolute EEG power and aperiodic activity of the power spectral density (PSD) slope, in association with subsequent autism risk and cognitive ability in a diverse cohort of children born preterm in South Africa. Participants were 71 preterm infants born between 25 and 36 weeks gestation (34.60 ± 2.34 weeks). EEG was collected during sleep between 39 and 41 weeks postmenstrual age adjusted (40.00 ± 0.42 weeks). The Bayley Scales of Infant Development and Brief Infant Toddler Social Emotional Assessment (BITSEA) were administered at approximately 3 years of age adjusted (34 ± 2.7 months). Aperiodic activity, but not the rhythmic oscillatory activity, at multiple electrode sites was associated with subsequent increased autism risk on the BITSEA at three years of age. No associations were found between the PSD slope or absolute EEG power and cognitive development. Our findings highlight the need to examine potential markers of subsequent autism risk in high-risk populations other than infants at familial risk.
Importance of Colostrum for Calf Health and development: A brief review

Colostrum is a form of milk produced by the mammary glands at the end of pregnancy. Passive antibody intake through the Colostrum during the early hours of birth is very important for calf survival. Consumption of high-quality Colostrum could reduce mortality, strengthen immunity, and increase the livability of calves. Therefore, calves must ensure their passive immunity by consuming Colostrum as soon as possible after their birth. This paper aims to review the benefits of Colostrum for calf health development.
Rapid adsorption of tetracycline from aqueous solution on fly ash

In this study, we use fly ash (FA), which is considered as the solid waste, to explore its absorption capacity of tetracycline (TC). We chose one kind of FA, which is obtained from factory, to use in the experiment. The effect of adsorbent dosages, pH, contact time, adsorption kinetics and isotherm were studied. The physical and chemical characteristics were analyzed by scanning elec tron microscopy, Fourier-transform infrared spectroscopy. As for adsorption kinetics of the FA, it is mostly consistent with the pseudo-second-order model, and the equilibrium time was attained after about 20 min. Besides, the maximum removal rate of TC by FA was about 87%. In this study, we found that Brunauer–Emmett–Teller model was the best fitted one compared with Langmuir isotherm model and Freundlich isotherm model, which indicated that it was a multi-molecular adsorption process. Also through the adsorption and characterization experiment, we suggested cation exchange was the major mechanism of TC adsorption on FA.
Impact of high-intensity interval training on cardio-metabolic health outcomes and mitochondrial function in older adults: a review

Exercise being a potent stimulator of mitochondrial biogenesis, there is a need to investigate the effects of high-intensity interval training (HIIT) among older adults. This review explores and summarizes the impact of HIIT on mitochondria and various cardio-metabolic health outcomes among older adults, healthy and with comorbid conditions. Electronic databases were scrutinized for literature using permutations of keywords related to (i) Elderly population (ii) HIIT (iii) Mitochondria, cell organelles, and (iv) cardio-metabolic health outcomes. Twenty-one studies that met the inclusion criteria are included in this review. HIIT is an innovative therapeutic modality in preserving mitochondrial quality with age and serves to be a viable, safe, and beneficial exercise alternative in both ill and healthy older adults.
Mycobacterium lepromatosis as Cause of Leprosy, Colombia

Leprosy is a granulomatous infection caused by infection with Mycobacterium leprae or M. lepromatosis. We evaluated skin biopsy and slit skin smear samples from 92 leprosy patients in Colombia by quantitative PCR. Five (5.4%) patients tested positive for M. lepromatosis, providing evidence of the presence of this pathogen in Colombia.
Combination of CENP-B Box Positive and Negative Synthetic Alpha Satellite Repeats Improves De Novo Human Artificial Chromosome Formation

Human artificial chromosomes (HACs) can be formed de novo by introducing large (>30 kb) centromeric sequences consisting of highly repeated 171-bp alpha satellite (alphoid) DNA into HT1080 cells. However, only a subset of transformed cells successfully establishes HACs. CENP-A chromatin and heterochromatin assemble on the HACs and play crucial roles in chromosome segregation. The CENP-B protein, which binds a 17-bp motif (CENP-B box) in the alphoid DNA, functions in the formation of alternative CENP-A chromatin or heterochromatin states. A balance in the coordinated assembly of these chromatin states on the introduced alphoid DNA is important for HAC formation. To obtain information about the relationship between chromatin architecture and de novo HAC formation efficiency, we tested combinations of two 60-kb synthetic alphoid sequences containing either tetO or lacO plus a functional or mutated CENP-B box combined with a multiple fusion protein tethering system. The combination of mutated and wild-type CENP-B box alphoid repeats significantly enhanced HAC formation. Both CENP-A and HP1α were enriched in the wild-type alphoid DNA, whereas H3K27me3 was enriched on the mutant alphoid array. The presence or absence of CENP-B binding resulted in differences in the assembly of CENP-A chromatin on alphoid arrays and the formation of H3K9me3 or H3K27me3 heterochromatin.
The Effectiveness of Ethanolic Extract of Centella asiatica (L.) on Healing Minor Recurrent Aphthous Stomatitis in Wistar Male Rats (Rattus norvegicus)

One of the most common oral diseases is Recurrent Aphthous Stomatitis (RAS) and the most common form is Minor RAS. Gotu kola leaves ( Centella asiatica (L.) Urban) contain active components that can help the healing process that widely used as traditional medicine. The aim of this study was to determine the effectiveness of the 70% ethanolic extract of C. asiatica on the healing of Minor RAS. This study is a true experimental with a Pretest-Posttest Randomized Control Group design. The purposive sampling technique is used. The sample of this study are 24 male wistar rats divided into 4 sample groups, a negative control group and 3 experimental groups (treatment with ethanolic extract of C. asiatica at a concentration of 25%, 50%, and 75%). The formation of the lesion minor RAS was by making a lesion on the lower labial oral mucosa of the rats by using a 10% H 2 O 2 solution, then giving the treatment in each group for 7 days twice a day. Observations were made by measuring the diameter of minor RAS lesions in all samples using a sliding caliper every morning for 7 days. This research conducted in August 2021. The results of the measurement of lesion diameter were tested by the Shapiro-Wilk normality test. One Way ANOVA test was performed, the results showed that there was no significant difference in the diameter of the lesion between experimental groups and negative control group (p>0.05). Ethanolic extract of C. asiatica did not significantly heal minor RAS lesions.

Isolated Femoral LCL Avulsion Fracture in the Adult Knee: Two Patient Cases and Literature Review

Avulsion injuries of the LCL most commonly occur at the fibular insertion. Femoral LCL avulsion injuries have only been previously described in pediatric patients or as multiligament knee injury components among adults. This case series with comprehensive literature review describes for the first time 2 cases of isolated LCL femoral avulsion fractures in adults including conservative treatment outcomes. Both patients sustained a strong varus stress mechanism to their right knee, following sport injury or road traffic accident. For both patients, a complete radiographic evaluation including X-rays, MRI, and CT scan confirmed no other associated knee lesions. The femoral LCL avulsion fractures that were observed were minimally displaced and noncomminuted. Furthermore, imagery suggested preserved integrity at the superior lateral genicular artery, adjacent articular capsule, and IT band. Based on clinical and imaging evaluations, the decision was made to follow conservative treatment. By 10 weeks postinjury, both patients were asymptomatic with early radiological fracture healing evidence. Comparative varus stress radiographs at 20° knee flexion revealed no side-to-side differences and clinical exam showed no posterolateral rotatory instability. The second patient case presented with mild femoral LCL attachment calcification on follow-up CT-scan. Following a detailed analysis of anatomic injury characteristics, we suggest that patients with isolated femoral LCL avulsion fractures have low secondary displacement risk provided SLGA, articular capsule, and IT band integrity are present. In contrast to high-grade ligamentous and distal avulsion LCL injuries, we recommend conservative treatment for patients who sustain these lesions.
Harnessing the Visual Salience Effect With Augmented Reality to Enhance Relevant Information and to Impair Distracting Information

Abstract This study investigated several visualizations, including enhancing relevant information and impairing distracting information, that harnessed the visual salience effect with augmented reality (AR) to assist people in searching for targets. The experiment used a scenario of shopping for food products where participants searched for the target product wearing an AR head-mounted display that presented the visualizations. In addition, the field-dependent (FD) and field-independent (FI) cognitive styles of users were investigated. First, FI participants completed the product selection tasks more quickly than FD participants when using the visualizations of enhancing relevant information but not the visualizations of impairing distracting information. Second, the visualizations of impairing irrelevant information improved the search speed but not the accuracy of FD participants compared to the visualizations of enhancing relevant information. Third, participants perceived a higher clarity of the highlighted items when they were highlighted with a frame rather than an overlay.
Endothelial Cells Activated by Extracellular Histones Promote Foxp3+ Suppressive Treg Cells In Vitro

Histones are widely recognized as pro-inflammatory mediators upon their release from the nucleus into the extracellular space. However, their impact on endothelial cell immunogenicity is unknown. Endothelial cells, Human Microvascular Endothelial cells 1 (HMEC1), have been exposed to recombinant histones in order to study their effect on the endothelial phenotype. We then studied the differentiation of CD4+-T lymphocytes subpopulations after three days of interaction with endothelial cells in vitro and observed that histone-treated endothelial cells differentiate a suppressive FoxP3+ T regulator subpopulation that expressed Human Leucocyte Antigen DR (HLA-DR) and Cytotoxic T-Lymphocyte-Associated protein 4 (CTLA4). Toll-Like Receptor 4 (TLR4) inhibition significantly decreased the expansion of these Treg cells. Moreover, blockade of Interleukin (IL)-6 and Intercellular Adhesion Molecule (ICAM)-1 in cocultures significantly decreased the expansion of Tregs, suggesting an IL-6 and ICAM-1 dependent pathway. Thus, beyond their inflammatory effects, extracellular histones may induce an increase of immunosuppressive Treg population via their action on endothelial cells. Further studies are needed to evaluate the impact on immunosuppression of an increase of peripheral suppressive Treg via endothelial cell activation by histones in vivo.
XFlag: Explainable Fake News Detection Model on Social Media

Abstract Social media allows any individual to disseminate information without third-party restrictions, making it difficult to verify the authenticity of a source. The proliferation of fake news has severely affected people’s intentions and behaviors in trusting online sources. Applying AI approaches for fake news detection on social media is the focus of recent research, most of which, however, focuses on enhancing AI performance. This study proposes XFlag, an innovative explainable AI (XAI) framework which uses long short-term memory (LSTM) model to identify fake news articles, layer-wise relevance propagation (LRP) algorithm to explain the fake news detection model based on LSTM, and situation awareness-based agent transparency (SAT) model to increase transparency in human-AI interaction. The developed XFlag framework has been empirically validated. The findings suggest the use of XFlag supports users in understanding system goals (perception), justifying system decisions (comprehension), and predicting system uncertainty (projection), with little cost of perceived cognitive workload.
Pitfalls in the hemostatic management of a liver transplantation

Liver Transplantation is fraught with thrombo-hemorrhagic complications, due to the precarious hemostasis of the recipient, anhepatic conditions, and the release of hemostatic factors from the allograft. Disseminated intravascular coagulation and its “flat-line” variant are common causes of hemorrhage and thrombosis, and frequently force the clinician along with a delicate balance between hemorrhage and thrombosis. We present a case that highlights some of the more challenging diagnostic and management decisions in liver transplantation and presents a safe and carefully structured approach to hyperfibrinolysis in liver transplantation.
Single Walled Carbon Nanotubes with Encapsulated Pt(Ii) Photocatalyst for the Oxidation of Sulfides in Water

A simple one-step synthesis of a heterogeneous photocatalyst based on the encapsulation of the quinolinate-platinum complex 1 in the inner cavity of Single Walled Carbon Nanotubes ( Pt1@oSWNT ) is presented. This strategy generates a robust and stable catalyst for photooxidations performed in water media. Pt1@oSWNT is characterized spectroscopically and microscopically to have encapsulated a 2.5 % wt. of the unaltered complex. This material, which only contained 0.04 mol% of 1 , is able to chemoselec-tively yield a wide variety of sulfoxides in water in the presence of air under 385 nm irradiation. The catalyst also presents afﬁnity for polyaromatic substrates, increasing the reaction rate as a function of the number of condensed rings, achieving turnover frequencies as high as 8187 h (cid:1) 1 . Moreover, the heterogeneous catalyst could be recycled for more than six consecutive reaction runs without losing its catalytic activity or detecting catalyst leaching.
Electoral Accountability and Control in US Cities

We consider a dynamic game of electoral competition with adverse selection, moral hazard, and imperfect monitoring. We show that this dynamic game can be estimated using a flexible maximum likelihood estimator. We implement the estimator using data from recent mayoral elections in large US cities with binding two-term limits. Our empirical findings suggest that there are large differences in performance among different types of mayors. We find an economically important degree of policy responsiveness, with effort accounting for a larger fraction of the total effect than selection. Finally, we evaluate several institutional reforms that promise to increase policy responsiveness.
Bridging social capital through the use of social networking sites: A systematic literature review

ABSTRACT The purpose of this study is to find out the impact of the use of social networking sites (SNS) use on bridging social capital (BRS). This paper also aimed to identify the popular medium used for developing BRS. A systematic literature review (SLR) was performed by following the preferred reporting items for systematic reviews and meta-analyses (PRISMA). This SLR was conducted based on Scopus, Web of Science and Google Scholar to collate and synthesize the findings of published studies by 2021. During the reported period, 29 quantitative studies fall under the inclusion criterion. The generalized findings indicated that SNS use has a significant and positive impact on bridging social capital (BRS). The relationship between SNS use and bridging capital is stronger in Western countries as compared to Eastern countries. Facebook is the mostly used medium for developing bridging social capital. Social networking sites (SNSs) offer a platform to develop new relations and strengthen weak ties. It also prioritized SNS-based social interaction for developing weak bonds, which further help to form bridging social capital within online communities. These findings support media designers in highlighting cultural differences while designing SNSs based applications. This is one of the first attempts to accumulate systematically published literature in the area of study during the reported period. The study’s outcomes are result-oriented contributions for marketers in developing marketing agendas and strategies compatible with consumer preferences while designing and improving SNS based information systems.
