Identification of Battery State of Health By Combining Machine Learning and Impedance Spectroscopy
Authors: Tang Qiaochu , Zhang Yunwei , Lee Alpha , Stimming Ulrich 
Published: February 2020

The possibility of diagnosing Li-ion battery’s state of health (SoH) and remaining useful life from electrochemical impedance spectra (EIS) using Machine Learning is investigated. The Gaussian Process (GP) with automatic relevance determination is used to identify degradation patterns without relying on any equivalent circuit models. The experiment consists of continuous charge-discharge cycling of commercial Li-ion coin cells. With the GP model trained with the entire spectrum measured on identical cells cycled under the same condition, the cycle number of a testing cell can be predicted by providing the corresponding EIS data. The trained GP model selected one frequency that is most indicative for the battery degradation, indicating the potential that the battery SoH can be diagnosed by measuring impedance at certain frequencies instead of taking a full-range EIS. Moreover, the GP model trained with all sets of data is able to identify the cycle number without knowing temperature or SoC, showing the possibility of developing a universal diagnosis methodology for battery management systems.

The emerging market of the Internet of Things, smart objects and others increase the demand for micro energy sources. Rechargeable Li-ion batteries are a well-known technology for energy storage. However, safety issues and high production costs constrain progress. Research on solid electrolytes, such as LiPON, was performed to evade leakage. But LiPON suffers from low ionic conductivity and a cost and time intensive production process. Another approach is the substitution of volatile and flammable organic electrolyte solvents with ionic liquids (IL), which display negligible vapor pressure and wide chemical, electrochemical, and thermal stability. Electrolyte solution based on ILs can be confined into inorganic porous networks forming so-called ionogels (IG), which are investigated as solid electrolyte materials. IGs combine low hazard and good ionic conductivity [1].
Silica-based IGs compatible with Li/LiCoO2 systems were prepared in a one-pot sol-gel process. The composition of the IG precursor solution and the influence of trifluoroacetic acid as catalyst were studied to obtain a fast condensation. Homogeneous and transparent IGs were obtained with a gelation time of less than 12 h. The physical properties of the host matrix were characterized by N2 sorption and SEM.
The silica host matrix is a 3D network predominantly built from 3-fold condensed silicon centres. Its structure changes from densely packed silica particles to open porous architecture.
The electrochemical performances of the IG deposited by spray coating under ambient contitions were evaluated by impedance spectroscopy measurements. First results show that these promising IGs may be successfully used as electrolyte in Li/LiCoO2 cells, with ionic conductivities up to 0.15 mScm-1. The coin cell batteries prepared with our IGs did not show dendritic growth after more than 100 cycles of galvanostatic cycling at a C/4 rate.
Study on Water Swellable Enzyme-Polymer Conjugate for Biosensor
Authors: Chung Yongjin , Ji Jungyeon , Kwon Yongchai 
Published: February 2020

Water swellable enzyme-polymer conjugate prepared by polyacrylic acid and glucose oxidase(PAA-GOx) is suggested to enhance a performance of biosensor. According to results, PAA-GOx shows better electrochemical performance although the amount of enzyme in biocatalyst using polyethyleneimine and graphene oxide composite(PEI-GO) is lower than that of glutaraldehyde-GOx(GA-GOx) conjugate. The catalytic activity and sensitivity are 98.0 μA cm-2 with 20mM of glucose in PBS solution and 6.9 μA cm-2 mM-1, which are ca. 10 times higher value compare to GA-GOx due to its high swellability in water. Due to the reason, PAA-GOx conjugate show an excellent ability to absorb water based electrolyte and cause high response and sensitivity through smooth mass transfer of glucose substrate to active site of enzyme. Moreover, the long term stability of catalyst is also improved due to the amide bonds prepared by carboxylic acid of PAA and amine of GOx and PEI.

Surface Recognition and Electron Transfer in Electroactive Bacterial Biofilms: Principal Component Analysis
Authors: Lebedev Nikolai , Yates Matthew , Griva Igor , Tender Leonard M. 
Published: February 2020

Bacterial electroactive biofilms attract researchers’ attention due to their ability for generation of electric current when electrons travel for very long, up to several tens microns, distance. It was demonstrated that this electron transfer ability correlates with the accumulation in the BF a c-type cytochrome (Cyt), but molecular nature of this Cyt, its spatial localization, interaction with the environment, regulation and the controlling factors are not understood. Bacterial cell polarity is an internal cell asymmetry that correlates with the cell ability to sense energy and metabolite sources, chemical signals, quorum signals, toxins, and movement in the desired directions. This ability also plays central role in cell attachment to various surfaces and biofilm formation. In the present work, we develop a new experimental approach for analyzing redox potential spatial distribution within individual bacterial cells and use this approach for identification how attachment to inorganic mineral, mica affects redox state inside individual G. sulfurreducens cells. The approach is based on confocal Raman microscopy allowing for precise estimation of redox state and localization of subcellular cytochromes. Applying Gaussian deconvolution and principal component analysis we are able to identify spectral signatures of cytochromes in different redox states and intracellular locations. Our results give a new tool for quick identification of internal and surface exposed cytochromes and their localization at bacterial cell sides facing the substrate and the solution. They open up the possibility for analyzing electrochemical potentials inside individual bacterial cells and indicate that Cyt redox state might be a driving force switching cell metabolic activity that leads to irreversible cell attachment to electrode, cell-to-cell association, and biofilm formation.

Noble Metal Free Molecular Based Anode for H2-O2 Fuel Cell
Authors: Reuillard Bertrand , Coutard Nathan , Artero Vincent 
Published: February 2020

The implementation of hydrogen as a sustainable energy vector relies on the efficient production and oxidation of H2 at low cost using electrolysers and fuel cells, respectively.[1] The hydrogen oxidation reaction (HOR) at the anode of state-of-the-art fuel cell is performed by catalysts based on rare and expensive platinum metal, making these fuel cells less suitable for industrial applications.[2] Hydrogenases (H2ase) enzymes are the only known catalysts able to compete with Pt for the HOR with turnover frequencies up to 10000 s-1 thanks to the complex environment of the active site.[3] These H2ases are also known for their sensitivity to a large number of inhibitors such as CO, H2S and O2 and can show limited stability over time.
In order to carry out H2 oxidation there are only a few examples of molecular catalysts able to perform this reaction near the thermodynamic potential with high turnover frequencies. They all belong to the family of Ni-based diphosphine complexes bearing integrated proton relays (Ni(P2N2)2), originally developed by the group of D. L. DuBois.[4] These bio-inspired catalysts have been immobilized onto carbon electrode surfaces and showed efficient H2 production and oxidation properties under acidic aqueous conditions.[5,6]

More recently, the modification of the outer coordination sphere of these Ni based catalysts with arginine (Ni(P2NArg2)2) moieties showed drastic improvement in the electrocatalytic HOR performance in homogeneous conditions. The immobilization of this catalyst onto a carbon nanotube modified electrode gave rise to high current densities for HOR, up to 20 mA cm-2.[7] We will show how the elaboration of porous nano-structures led to further increased performance of the molecular based anode.

The effect of blood flow restriction exercise on exercise-induced hypoalgesia and endogenous opioid and endocannabinoid mechanisms of pain modulation
Authors: Hughes Luke , Patterson Stephen David 
Published: February 2020

This study aimed to investigate and compare the magnitude of exercise-induced hypoalgesia (EIH) with low-intensity blood flow restriction (BFR) resistance exercise (RE) at varying pressures to other intensities of resistance exercise and examine endogenous mechanisms of pain reduction. Twelve individuals performed four experimental trials involving unilateral leg press exercise in a randomized crossover design: low-load RE at 30% of one repetition maximum (1RM), high-load RE (70% 1RM), and BFR-RE (30% 1RM) at a low and high pressure. BFR pressure was prescribed relative to limb occlusion pressure at 40% and 80% for the low- and high-pressure trials. Pressure pain thresholds (PPT) were assessed before and 5 min and 24 h following exercise in exercising and nonexercising muscles. Venous blood samples were collected at the same timepoints to determine plasma concentrations of beta-endorphin and 2-arachidonoylglycerol. High-pressure BFR-RE increased PPTs in the exercising limb to a greater extent than all other trials. Comparable systemic EIH effects were observed with HLRE and both BFR-RE trials. PPTs in the exercising limb remained elevated above baseline at 24 h postexercise following both BFR-RE trials. Postexercise plasma beta-endorphin concentration was elevated during the BFR-RE trials. No changes to 2-arachidonoylglycerol concentration were observed. High pressure BFR-RE causes a greater EIH response in the exercising limb that persists for up to 24 h following exercise. The reduction in pain sensitivity with BFR-RE is partly driven by endogenous opioid production of beta-endorphin. BFR-RE should be investigated as a possible pain-modulation tool in individuals with acute and chronic pain. NEW & NOTEWORTHY High-pressure blood flow restriction (BFR) causes a greater hypoalgesia response in the exercising limb (48%) compared with light and heavy load resistance exercise (10–34%). Performing light load resistance exercise with BFR causes systemic hypoalgesia comparable with heavy load resistance exercise (10–18%). BFR resistance exercise prolonged the exercise-induced hypoalgesia response for 24 h in the exercising limb (15% and 24%, respectively). Activation of endogenous opioid production and a conditioned pain modulation effect partly mediate the relationship between exercise and hypoalgesia.
Did Artapanus Use the Septuagint?
Authors: Hitchcock Jason D. 
Published: February 2020

Abstract
Many contend that the Hellenistic-era author Artapanus employed the LXX translation, albeit in relatively liberal fashion. Departures from LXX narratives are attributed to his literary and apologetic interests. Although he may have relied upon a combination of oral and written sources, most scholars presuppose his primary reliance upon the LXX. This paper evaluates arguments for Artapanus’s use of the LXX, highlighting the paucity of decisive verbal links and weakness of other proposed linguistic correspondences, and attributing the emergence of similar Greek naming conventions between Artapanus and the LXX to the shared Egyptian provenance. These findings challenge the prevailing consensus concerning Artapanus’s source for Jewish traditions.

Published: February 2020

Within the genus Melanogaster Rondani, 1857, the group of species characterized by their yellow wing base was named as M. jaroslavensis group and revised for the first time. Redescriptions of M. jaroslavensis (Stackelberg, 1922), M. kirgisorum (Stackelberg, 1952), and M. tadzhikorum (Stackelberg, 1952) are provided. A new species of the M. jaroslavensis group, Melanogaster raccoon sp. nov., from Afghanistan, is described. The male of this new species differs from those of other known Melanogaster species by the following combination of characters: yellowish wing base, pale body pile, without dark pile, almost flat face, and surstyli short and emarginated apically in ventral view. Females of M. raccoon sp. nov. differ from those of any other Melanogaster species by a combination of yellowish wing base and frons without transverse furrows. An identification key to the species of the M. jaroslavensis group is presented.

A new fish species, Stolephorus tamilensis sp. nov., is described from the East coast of India. The major distinguishing characters are 5–6 small needle-like pre-pelvic scutes on belly; maxilla tip pointed, reaching to border of operculum, concave and indented in the preoperculum; 25–28 gill rakers on lower lobe of the first branchial arch; dorsal fin without spine; 17–19 anal-fin rays. Moreover, S. tamilensis sp. nov. present higher average genetic divergence values at mitochondrial cytochrome c oxidase subunit I and 16S rDNA loci in comparison with congeners. Also, nucleotide diagnostic characters exclusive to S. tamilensis are identified. Neighbor-joining analysis revealed close relation between S. tamilensis and S. andhraensis.

Authors: Qiao Shan , Jiang Yanping , Li Xiaoming 
Published: February 2020

Objectives: The aim of this study was to evaluate the effectiveness of health promotion interventions in delaying telomere shortening (a biomarker for aging). Data Source: PubMed, PsychINFO, EMBASE, CINAHL, and Cochrane Library databases. Study Inclusion and Exclusion Criteria: Inclusion criteria: (1) empirical studies involving human subjects; (2) health promotion intervention studies including both randomized control trials (RCTs) and non-RCTs.; (3) measured telomere length as an intervention outcome; and (4) were written in English. Exclusion criteria: (1) observational studies without any health promotion intervention practices and (2) did not report intervention effects. Data Extraction: Data extraction was performed by two reviewers following the preferred reporting items for systematic reviews and meta-analysis guidelines. Data Synthesis: Substantial heterogeneity in intervention type and study design in the included studies precluded a meta-analysis. We conducted a narrative synthesis instead. Results: Thirty studies were included in the review, of which 16 were RCTs. One-third of the included studies reported significant intervention impacts in delaying telomere shortening, with relatively consistent significant results emerged from weight-loss interventions and interventions involving multiple lifestyle modification components (eg, diet and exercise). Most of supplement intervention studies observed null effects in telomere length. Conclusions: Weight-loss and comprehensive lifestyle intervention strategies show encouraging impacts in delaying telomere shortening. More rigorous studies targeting populations at different age stages through life span are needed.

Authors: Hashemi Hassan , Pakzad Reza , Khabazkhoob Mehdi , Yekta Abbasali , Emamian Mohammad Hassan , Fotouhi Akbar 
Published: February 2020

Purpose: To determine the distribution of ocular biometric components, including axial length, lens thickness, and vitreous chamber depth, their relationship with personal characteristics, and spherical equivalent refraction after adjusting axial length and vitreous chamber depth for personal characteristics. Methods: Among 6- to 12-year-old children, urban subjects were selected using random cluster sampling, and in rural areas, all eligible subjects were considered for enrollment. Ocular biometrics were measured using BioGraph. Data were summarized as mean and 95% confidence intervals. Linear regression was used to investigate the relationships between the study variables. Results: Data from 4938 children were analyzed. Mean axial length, lens thickness, and vitreous chamber depth were 23.02 (95% confidence interval: 22.97–23.07) mm, 3.48 (95% confidence interval: 3.47–3.49) mm, and 20.63 (95% confidence interval: 20.59–20.66) mm, respectively. According to the multiple linear regression model, axial length and vitreous chamber depth associated positively with height (β = 0.020, P < 0.001; β = 0.018, P < 0.001, respectively) and inversely with female gender (β = −0.522, P < 0.001; β = −0.386, P < 0.001, respectively). Also lens thickness correlated inversely with age (β = −0.019, P < 0.001) and positively with female gender (β = 0.043, P < 0.001). After adjusting for personal characteristic, spherical equivalent had an inverse relationship with axial length (β = −0.441, P < 0.001) and a positive relationship with lens thickness (β = 0.423, P < 0.001). Among the studied variables, axial length had the strongest association with spherical equivalent (standardized coefficient: −0.39). Conclusion: This cross-sectional study showed a general pattern of ocular biometric components. The axial length value was almost similar to European countries, but less than that in the Eastern and Southeast Asian populations. By increasing age, axial length and vitreous chamber depth increased while lens thickness and spherical equivalent decreased. Among all ocular biometric components, axial length was strongest determinant for spherical equivalent.
Gaining Large Coverage With Small Island Pedicle Flaps in Tight Cosmetic Subunits: Taking Advantage of Rotation and Pincer Principles on the Nasal Ala
Authors: Wong Noelle , Kossintseva Irèn 
Published: February 2020

BackgroundIsland pedicle flaps (IPFs) are widely used in reconstructive surgery due to their versatility, tissue efficiency, and excellent clinical outcomes. While IPF rotations and ‘pincer flap’ modifications have previously been sparsely described, they are not often discussed in the literature.ObjectiveWe demonstrate the use of both rotating IPFs and pincer techniques for defects traditionally considered too large for classic IPF design on the nasal ala.MethodsForty-four patients underwent alar repair using the rotation or combined rotation with pincer modification to the standard IPF technique from August 2014 to May 2017. Our technique is described and case examples are presented with photographs.ResultsForty-four patients with an average alar defect size of 1.2 cm underwent repair using rotation only or rotation with pincer modification of the classic IPF approach.ConclusionsReconstruction of large defects in small facial cosmetic subunits such as the nasal ala can be performed using principles of both rotating IPFs and the ‘pincer flap’ technique. The degree of rotation is directly related to the length of coverage. Modifications to the flap are straightforward to perform. Using these techniques, larger defects that previously would have been reconstructed using flaps that cross cosmetic boundaries can now be reconstructed within the same cosmetic unit, thus, improving aesthetic outcomes.
CT scan of the placement of the femoral tunnel in combined anterior cruciate ligament and anterior lateral ligament reconstruction by a single femoral tunnel using the outside-in technique
Authors: Russo Anne Pauline , Joly Benjamin , Gervaise Alban , Choufani Camille , Caubere Alexandre , Versier Gilbert , Barbier Olivier 
Published: February 2020

Background: The main difficulty with this ALL reconstruction method is the placement of the femoral tunnel as isometrically as possible. The femoral insertion of the ALL is usually located one centimeter posteriorly and proximal to the lateral epicondyle, at the level of the Lemaire vessels. The purpose of our study was to evaluate the placement of the femoral tunnel in ligament reconstruction by combined ACL and ALL reconstruction with a single femoral tunnel using the outside-in technique. Our hypothesis was that a single femoral tunnel by outside-in technique would allow satisfactory placement of the femoral insertion of the ALL.. Methods: We conducted a retrospective bi-centric study of all patients who underwent combined ACL and ALL reconstruction surgery with a common outside-in femoral technique. A postoperative low-dose knee CT scan with multiplane reconstructions was performed after patient consent. After locating the top of the epicondyle on three-dimensional CT scan reconstructions, the distances between the top of the lateral epicondyle and the center of the femoral tunnel in the frontal and sagittal planes were measured. These measurements were taken by a surgeon and a radiologist. Results: 45 patients were included and the average age was 29 years (17-39). 30 patients had a CT scan. Analysis of the placement of the femoral tunnel showed that 10 tunnels were placed posteriorly and proximal to the top of the lateral epicondyle. Conclusion: This study did not confirm our hypothesis. Combined ACL and ALL reconstruction by a single tunnel did not provide access to the isometric point of the femoral insertion of the ALL in a reproducible manner, despite open intra-operative identification of this point. This study highlights the difficulty of locating the femoral isometric point with a standard outside-in femoral guide. Developing a specific femoral guide might be useful.
