Probing Local Force Propagation in Tensed Fibrous Gels
Authors: Goren Shahar , Levin Maayan , Brand Guy , Lesman Ayelet , Sorkin Raya 
Published: November 2022

AbstractFibrous hydrogels are a key component of soft animal tissues. They support cellular functions and facilitate efficient mechanical communication between cells. Due to their nonlinear mechanical properties, fibrous materials display non‐trivial force propagation at the microscale, that is enhanced compared to that of linear‐elastic materials. In the body, tissues are constantly subjected to external loads that tense or compress them, modifying their micro‐mechanical properties into an anisotropic state. However, it is unknown how force propagation is modified by this isotropic‐to‐anisotropic transition. Here, force propagation in tensed fibrin hydrogels is directly measured. Local perturbations are induced by oscillating microspheres using optical tweezers. 1‐point and 2‐point microrheology are combined to simultaneously measure the shear modulus and force propagation. A mathematical framework to quantify anisotropic force propagation trends is suggested. Results show that force propagation becomes anisotropic in tensed gels, with, surprisingly, stronger response to perturbations perpendicular to the axis of tension. Importantly, external tension can also increase the range of force transmission. Possible implications and future directions for research are discussed. These results suggest a mechanism for favored directions of mechanical communication between cells in a tissue under external loads.

Published: November 2022

AbstractLithium‐sulfur battery suffers from sluggish kinetics at low temperatures, resulting in serious polarization and reduced capacity. Here, this work introduces medium‐entropy‐alloy FeCoNi as catalysts and carbon nanofibers (CNFs) as hosts. FeCoNi nanoparticles are in suit synthesized in cotton‐derived CNFs. FeCoNi with atomic‐level mixing of each element can effectively modulate lithium polysulfides (LiPSs), multiple components making them promising to catalyze more LiPSs species. The higher configurational entropy endows FeCoNi@CNFs with extraordinary electrochemical activity, corrosion resistance, and mechanical properties. The fractal structure of CNFs provides a large specific surface area, leaving room for volume expansion and Li2S accumulation, facilitating electrolyte wetting. The unique 3D conductive network structure can suppress the shuttle effect by physicochemical adsorption of LiPSs. This work systematically evaluates the performance of the obtained Li2S6/FeCoNi@CNFs electrode. The initial discharge capacity of Li2S6/FeCoNi@CNFs reaches 1670.8 mAh g−1 at 0.1 C under ‐20 °C. After 100 cycles at 0.2 C, the capacity decreases from 1462.3 to 1250.1 mAh g−1. Notably, even under ‐40 °C at 0.1 C, the initial discharge capacity of Li2S6/FeCoNi@CNFs still reaches 1202.8 mAh g−1. After 100 cycles at 0.2 C, the capacity retention rate is 50%. This work has important implications for the development of low‐temperature Li‐S batteries.

Published: November 2022

AbstractWith an extremely high theoretical energy density, poly(ethylene oxide) (PEO)‐based solid‐state lithium‐sulfur (Li‐S) batteries are emerging as one of the most feasible and safest battery storage systems. However, the long‐term cycling performance is severely impeded by polysulfides (Li2Sn, n = 4–8) shuttling and terrible electrode passivation from the electronic insulating Li2S. Here, a novel cathode through chemically grafted 1‐Ethyl‐3‐methylimidazolium bromide (EMIM+‐Br−) to carbon nanotube (CNTs) for PEO‐based Li‐S batteries is reported (CNTs@EMIM‐Br/S). Concretely, bi‐functional mediator EMIM+‐Br− not only inhibits the polysulfides shuttling by strong chemical interactions via EMIM+, but also facilitates the electrochemical kinetics for promoting the formation of 3D particulate Li2S through high donor anion (Br−). Satisfactorily, dual‐function CNTs@EMIM‐Br/S cathode exhibits high sulfur utilization with the capacity of up to 1298 mAh g−1, and keeps high capacity retention of 80.2% at 0.2 C after 350 cycles, exceeding that of many reported PEO‐based solid‐state Li‐S batteries. This work will open a new door for rationally designed architecture to enable the practical applications of advanced Li‐S batteries.
SMART Silly Putty: Stretchable, Malleable, Adherable, Reusable, and Tear‐Resistible Hydrogels
Authors: Chen Mingtao , Murphy Brendan B. , Wang Yuchen , Vitale Flavia , Yang Shu 
Published: November 2022

AbstractCell engineering, soft robotics, and wearable electronics often desire soft materials that are easy to deform, self‐heal readily, and can relax stress rapidly. Hydrogels, a type of hydrophilic networks, are such kind of materials that can be made responsive to environmental stimuli. However, conventional hydrogels often suffer from poor stretchability and repairability. Here, hydrogels consisting of boronic ester dynamic covalent bonds in a double network of poly(vinyl alcohol)/boric acid and chitosan are synthesized, which demonstrate extreme stretchability (up to 310 times the original length), instant self‐healing (within 5 s), and reusability and inherent adhesion. Their instant stress relaxation stems from a low activation energy of the boronic ester bond exchange (≤20 kJ mol−1) and contributes to the extreme stretchability and self‐healing behaviors. Various water‐dispersible additives can be readily incorporated in the hydrogels via hand kneading for potential applications such as soft electronics, bio‐signal sensing, and soft artificial joints.

Published: November 2022

AbstractThe practical application of Li‐S batteries is seriously hindered due to its shuttle effect and sluggish redox reaction, which requires a better functional separator to solve the problems. Herein, polypropylene separators modified by MoS2 nanosheets with atomically dispersed nickel (Ni‐MoS2) are prepared to prevent the shuttle effect and facilitate the redox kinetics for Li‐S batteries. Compared with pristine MoS2 nanosheets, Ni‐MoS2 nanosheets exhibit both excellent adsorption and catalysis performance for overcoming the shuttle effect. Assembled with this novel separator, the Li‐S batteries exhibit an admirable cycling stability at 2 C over 400 cycles with 0.01% per cycle decaying. In addition, even with a high sulfur loading of 7.5 mg cm−2, the battery still provides an initial capacity of 6.9 mAh cm−2 and remains 5.9 mAh cm−2 after 50 cycles because of the fast convention of polysulfides catalyzed by Ni‐MoS2 nanosheets, which is further confirmed by the density functional theory (DFT) calculations. Therefore, the proposed strategy is expected to offer a new thought for single atom catalyst applying in Li‐S batteries.
Zero‐knowledge‐based distributed auditing protocol

Published: November 2022

AbstractBlockchain‐based data outsourcing has attracted a huge deal of attention in recent years. However, key management and reliance on pre‐defined or randomly‐selected third‐party auditors (TPAs) are still challenging owing to refusing to collaborate or break auditing policies. Additionally, it is impossible to store secrets in smart contracts (SCs) for signing or auditing. Thus, in the present study, a zero‐knowledge (ZK)‐based distributed auditing protocol (DAP) is provided. In this protocol, a user‐based key generation mechanism offers users security against curious authorities based on no TPA causing them to reveal no knowledge about under‐auditing data. Based on Pointcheval's and Sanders's signature scheme, as a ZK‐based randomizable signature applied in an SC to handle the auditing process, the proposed DAP provides confidential transactions and user accountability. Evaluation indicates that the proposed ZK‐based DAP is efficient for the user side and it is the fastest DAP in the blockchain.
Characterization of Physicochemical Properties of Hypochlorite Oxidized Starches and Their Suitability for Making Starch Noodles
Authors: Shi Runjie , Tang Ning , Zhang Xiaojun , Cheng Yongqiang 
Published: November 2022

AbstractThe effects of hypochlorite oxidation on physicochemical properties of mung bean, potato, and pea starches, and the suitability of oxidized starches for making starch noodles are investigated. The formation of carboxyl groups in starches during the oxidation is more favorable under milder alkaline conditions (pH 8). The oxidized starches show a decrease in viscosity but an increase in conclusion temperature and gelatinization enthalpy due to the introduction of carboxyl groups. Moreover, the observed increase or decrease is highly correlated with the carboxyl contents of the oxidized starches. In addition, the introduction of carboxyl groups can effectively retard the starch retrogradation as indicated by changes in the light transmittance. The quality of the starch noodles can be improved by adding oxidized starches, and 5% is an appropriate amount for making starch noodles with respect to the overall quality.

Authors: Travail Victoria , Peak Kerry 
Published: November 2022

AbstractA 1‐year 4‐month‐old, male, neutered domestic longhair was presented for investigation of lameness and lethargy. Pyrexia and swelling of the left antebrachium was noticed on clinical examination. Despite treatment with various antibiotics (cefovecin, then amoxicillin and marbofloxacin), the pyrexia and lameness persisted. A computed tomography scan revealed a cavitary lesion and diffuse soft tissue swelling in the left axilla/thoracic wall, with associated moderate to marked lymphadenomegaly of multiple lymph nodes. Aspirates from the cavitary lesions revealed neutrophilic inflammation, and the lymph nodes were consistent with reactive lymphoid hyperplasia and neutrophilic lymphadenitis. Routine aerobic and anaerobic bacterial cultures were negative. AMycoplasmaculture was positive, and theMycoplasma felispolymerase chain reaction was positive at a high level (Ct 16.6). The patient was subsequently treated with doxycyline and the clinical signs resolved. The difficulty of culturingMycoplasmaspp. should raise the awareness of veterinarians to perform specific culture or polymerase chain reaction forMycoplasmaspp.
Green stormwater infrastructure: A critical review of the barriers and solutions to widespread implementation

Published: November 2022

AbstractRapid urbanization, aging infrastructure, and climate change impacts have put a strain on existing stormwater drainage systems. One commonly acknowledged solution to relieve such stress is Green Stormwater Infrastructure (GSI). Interest in GSI technology has been growing. However, the level of implementation in many areas around the world lags behind the interest level. This study aims to critically review the body of literature from the last decade to determine the main barriers to wide adoption and the offered solutions to overcome them. Based on a review of 92 peer‐reviewed journal articles published between 2012 and 2022, we classify barriers and solutions into six categories: socio‐cultural, financial, institutional and governance, legislative and regulatory, technical, and biophysical. Based on observations and conclusions from the reviewed articles, we recommend the following pillars and considerations for more GSI adoption: increasing awareness and outreach programs; enhancing knowledge and data co‐production and dissemination; acknowledging interdependency and context‐specificity of many of the challenges and solutions; prioritizing integrated and participatory watershed planning; overcoming institutional path‐dependencies; prioritizing innovative solutions; giving specific consideration to maintenance protocols; considering the role of public entities; and actively engaging with communities.This article is categorized under:

Framing Police Encounters: The Dramaturgy of Authority
Authors: Bielejewski Aaron 
Published: November 2022

AbstractA key feature of police work, and arguably the defining feature of the entire institution of policing, is the police encounter: any of the variety of situations in which police officers engage in face-to-face encounters with non-police individuals. Encounters between police and citizens take place in public and in private, at work and at home, during the day and at night; in contexts which can be familiar and routine to police or unique and problematic. They can involve individuals known to the police or strangers who only become known to the officers within the context of the encounter.

Comprehensive monitoring of a special mixture of prominent endocrine disrupting chemicals in human urine using a carefully adjusted hydrolysis of conjugates
Authors: Denghel Heike , Göen Thomas 
Published: November 2022

AbstractMany xenobiotics were identified as possible endocrine disruptors during the last decades. Structural analogy of these substances to natural hormones may lead to agonists or antagonists of hormone receptors. For a comprehensive human biomonitoring of such substances, we developed a simple, reliable, and highly sensitive method for the simultaneous monitoring of the parameters bisphenol A, triclosan, methylparaben, ethylparaben, propylparaben, butylparaben, benzophenone-1, benzophenone-3, 3,5,6-trichloropyridin-2-ol, p-nitrophenol, genistein, and daidzein in urine. Thereby, optimization of the enzymatic hydrolysis and the use of β-glucuronidase from E. coli K12 as well as sulfatase from Aerobacter aerogenes ensures the acquisition of intact analytes without cleavage of ester bonds among parabens. Validation of the method revealed limits of detection between 0.02 and 0.25 µg/L as well as limits of quantification between 0.08 and 0.83 µg/L. Thereby, the use of analyte-free surrogate matrix for calibration and control material influenced the sensitivity of the procedure positively. Furthermore, excellent precision in and between series was observed. Good absolute and relative recoveries additionally proved the robustness of the multimethod. Thus, the procedure can be applied for exploring the exposome to these prominent endocrine disruptors in the general population.

Published: November 2022

Abstract
Two diazotrophic cyanobacteria (Anabaena cylindrica PCC 7122 and Nostoc sp. PCC 7120) were cultivated to produce cyanophycin, a nitrogen reserve compound, under nitrogen fixing conditions. In preliminary continuous experiments, Nostoc sp. was shown to be more efficient, accumulating a higher amount of cyanophycin and showing a greater capability to fix atmospheric nitrogen in the biomass (67 mgN d−1 of fixed nitrogen per liter of culture). The operating conditions were then optimized to maximize the cyanophycin productivity: the effect of incident light intensity, residence time and nitrogen availability were investigated. Nitrogen availability and/or pH played a major role with respect to biomass production, whereas phosphorus limitation was the main variable to maximize cyanophycin accumulation. In this way, it was possible to achieve a stable and continuous production of cyanophycin (CGP) under diazotrophic conditions, obtaining a maximum cyanophycin productivity of 15 mgCGP L−1 d−1.

Key points
• Diazotrophic cyanobacteria produce stable amount of cyanophycin in continuous PBR.
• Nostoc sp. proved to be more efficient in producing cyanophycin than Anabaena sp.
• P deprivation is the major variable to increase cyanophycin productivity in continuous.
Imputation Strategies for Clustering Mixed-Type Data with Missing Values
Authors: Aschenbruck Rabea , Szepannek Gero , Wilhelm Adalbert F. X. 
Published: November 2022

Abstract Incomplete data sets with different data types are difficult to handle, but regularly to be found in practical clustering tasks. Therefore in this paper, two procedures for clustering mixed-type data with missing values are derived and analyzed in a simulation study with respect to the factors of partition, prototypes, imputed values, and cluster assignment. Both approaches are based on the k-prototypes algorithm (an extension of k-means), which is one of the most common clustering methods for mixed-type data (i.e., numerical and categorical variables). For k-means clustering of incomplete data, the k-POD algorithm recently has been proposed, which imputes the missings with values of the associated cluster center. We derive an adaptation of the latter and additionally present a cluster aggregation strategy after multiple imputation. It turns out that even a simplified and time-saving variant of the presented method can compete with multiple imputation and subsequent pooling.

Published: November 2022

Abstract
Introduction
To compare sutureless deep sclerectomy to conventional deep sclerectomy regarding their lowering effect on intraocular pressure (IOP) in cases with open-angle glaucoma.

Methods
This is a prospective interventional randomized comparative study that included 60 eyes of 50 patients with open-angle glaucoma (OAG) who were indicated for surgical intervention. Patients were recruited from the glaucoma subspecialty clinic of the Cairo University teaching hospital and were divided into two groups: group A (underwent sutureless deep sclerectomy) and group B (underwent conventional deep sclerectomy).

Results
Both surgeries showed significant reduction of IOP all through the study period: in group A, mean reduction was 71.37%, 53.35%, 50.3%, and 44.33% at 1st day, 1 month, 3 months, and 6 months respectively, and in group B, mean reduction was 57.62%, 40.63%, 37.41%, and 31.68% at 1st day, 1 month, 3 months, and 6 months, respectively. Comparison between percentage of reduction in both groups showed no statistically significant difference. Also, use of anti-glaucoma medications dropped significantly at 6 months postoperatively in both groups with no significant difference between the 2 groups. Regarding reported complications, 12.9% in group A and 10.3% in group B presented with non-serious complications. One month postoperatively, UBM detected non-functioning blebs in 6.4% of group A and 3.4% in group B. Other cases with non-functioning blebs were detected at 3 and 6 months postoperatively, and all cases were managed.

Conclusion
Sutureless deep sclerectomy seems to be a safe and effective modification, with significant IOP reduction in POAG.
Die Subventionierung des Gaspreises als Alternative zur Abschöpfung von „Übergewinnen“
Authors: Höffner Eckhard , Schubert Hermann 
Published: November 2022

ZusammenfassungIm Zusammenhang mit der Steigerung der Preise für Energie und den bei einzelnen Unternehmen stark gestiegenen Gewinnen sind Forderungen nach einer Übergewinnsteuer laut geworden. Die Bundesregierung spricht von Zufallsgewinnen, im Englischen „windfall“ (Fallobst) profits. Das Verständnis von diesen Gewinnen als außergewöhnlich und unverdient beruht wesentlich darauf, dass sie nicht durch eigene Leistung erwirtschaftet seien, sondern Folge der Preissteigerung im Zusammenhang mit dem Angriff Russlands auf die Ukraine und der Steigerung der Gaspreise. Die Profitierenden gelten einerseits als Krisenoder Kriegsgewinner:innen, während auf der anderen Seite die hohen Energiekosten als eine wesentliche Ursache für eine drohende schwere Rezession und Inflation (Stagflation) ausgemacht werden; ganz abgesehen von der Unsicherheit hinsichtlich der Energieversorgung auf dem bisherigen Niveau.
