AbstractMg‐Ca alloys have emerged as a promising research direction for biomedical implants in the orthopedic field. However, their clinical use is deterred by their fast corrosion rate. In this work, a pH stimuli‐responsive silk‐halloysite (HNT)/phytic acid (PA) self‐healing coating (Silk‐HNT/PA) is constructed to slow down the corrosion rate of Mg‐1Ca alloy and its cell viability and osteogenic differentiation ability are enhanced. The Silk‐HNT/PA coating exhibits appealing active corrosion protection, by eliciting pH‐triggerable self‐healing effects, while simultaneously affording superior biocompatibility and osteogenic differentiation ability. Moreover, in vivo studies by histological analysis also demonstrate better osseointegration for the Silk‐HNT/PA coated Mg‐1Ca alloy. In summary, the Silk‐HNT/PA coating in the present study has great potential in enhancing the biomedical utility of Mg alloys.

AbstractThe assembly of metal nanoparticles and targets to be detected in a small light probe volume is essential for achieving sensitive in‐solution surface‐enhanced Raman spectroscopy (SERS). Such assemblies generally require either chemical linkers or templates to overcome the random diffusion of the colloids unless the aqueous sample is dried. Here, a facile method is reported to produce 3D multiscale assemblies of various colloids ranging from molecules and nanoparticles to microparticles for sensitive in‐solution SERS detection without chemical linkers and templates by exploiting photothermally driven convective flow. The simulations suggest that colloids sub 100 nm in diameter can be assembled by photothermally driven convective flow regardless of density; the assembly of larger colloids up to several micrometers by convective flow is significant only if their density is close to that of water. Consistent with the simulation results, the authors confirm that the photothermally driven convective flow is mainly responsible for the observed coassembly of plasmonic gold nanorods with either smaller molecules or larger microparticles. It is further found that the coassembly with the plasmonic nanoantennae leads to dramatic Raman enhancements of molecules, microplastics, and microbes by up to fivefold of magnitude compared to those measured in solution without the coassembly.
Roadside unit‐based pseudonym authentication in vehicular ad hoc network
Authors: Stephen Steffie Maria , Jaekel Arunita 
Published: May 2022

AbstractInformation sharing among vehicles is an essential component of an Intelligent Transportation System (ITS), but must take into consideration the security and privacy requirements of the network participants. Vehicular Ad Hoc Network (VANET) is a pervasive network, where vehicles communicate wirelessly with nearby vehicles, infrastructure nodes, and other connected devices to improve road safety and provide other useful services. Security of VANET can be improved by ensuring that only authorized vehicles can participate in the network. This research proposes a new approach that uses roadside units (RSUs) to authenticate safety messages and notify vehicles about any unauthorized messages/senders. We present a three‐tier architecture with a distributed blockchain to securely maintain the identity of all vehicles in the network. The use of this RSU‐based approach helps to reduce the computational overhead on the On‐board unit (OBU) of individual vehicles and does not require the transmission of lengthy certificates and certificate revocation lists with each message. Simulation results indicate that the proposed approach achieves improved performance compared to existing techniques in terms of both authentication delay and channel load.
Mammalian proteome expansion by stop codon readthrough
Authors: Manjunath Lekha E. , Singh Anumeha , Som Saubhik , Eswarappa Sandeep M. 
Published: May 2022

AbstractRecognition of a stop codon by translation machinery as a sense codon results in translational readthrough instead of termination. This recoding process, termed stop codon readthrough (SCR) or translational readthrough, is found in all domains of life including mammals. The context of the stop codon, local mRNA topology, and molecules that interact with the mRNA region downstream of the stop codon determine SCR. The products of SCR can have localization, stability, and function different from those of the canonical isoforms. In this review, we discuss how recent technological and computational advances have increased our understanding of the SCR process in the mammalian system. Based on the known molecular events that occur during SCR of multiple mRNAs, we propose transient molecular roadblocks on an mRNA downstream of the stop codon as a possible mechanism for the induction of SCR. We argue, with examples, that the insights gained from the natural SCR events can guide us to develop novel strategies for the treatment of diseases caused by premature stop codons.This article is categorized under:

Published: May 2022

Abstract
We present the two-loop mixed strong-electroweak virtual corrections to the neutral current Drell-Yan process and we provide, as supplementary material, the explicit formulae of the infrared-subtracted finite remainder. The final state collinear singularities are regularised by the lepton mass. The evaluation of all the relevant Feynman integrals, including those with up to two internal massive lines, has been worked out relying on analytical and semi-analytical techniques, in the case of complex-valued masses.
Regular solutions of a functional equation derived from the invariance problem of Matkowski means

AbstractThe main result of the present paper is about the solutions of the functional equation$$\begin{aligned} F\Big (\frac{x+y}{2}\Big )+f_1(x)+f_2(y)=G(g_1(x)+g_2(y)),\quad x,y\in I, \end{aligned}$$F(x+y2)+f1(x)+f2(y)=G(g1(x)+g2(y)),x,y∈I,derived originally, in a natural way, from the invariance problem of generalized weighted quasi-arithmetic means, where$$F,f_1,f_2,g_1,g_2:I\rightarrow {\mathbb {R}}$$F,f1,f2,g1,g2:I→Rand$$G:g_1(I)+g_2(I)\rightarrow {\mathbb {R}}$$G:g1(I)+g2(I)→Rare the unknown functions assumed to be continuously differentiable with$$0\notin g'_1(I)\cup g'_2(I)$$0∉g1′(I)∪g2′(I), and the setIstands for a nonempty open subinterval of$${\mathbb {R}}$$R. In addition to these, we will also touch upon solutions not necessarily regular. More precisely, we are going to solve the above equation assuming first thatFis affine onIand$$g_1$$g1and$$g_2$$g2are continuous functions strictly monotone in the same sense, and secondly that$$g_1$$g1and$$g_2$$g2are invertible affine functions with a common additive part.
Density of Small Singular Values of the Shifted Real Ginibre Ensemble
Authors: Cipolloni Giorgio , Erdős László , Schröder Dominik 
Published: May 2022

AbstractWe derive a precise asymptotic formula for the density of the small singular values of the real Ginibre matrix ensemble shifted by a complex parameter z as the dimension tends to infinity. For z away from the real axis the formula coincides with that for the complex Ginibre ensemble we derived earlier in Cipolloni et al. (Prob Math Phys 1:101–146, 2020). On the level of the one-point function of the low lying singular values we thus confirm the transition from real to complex Ginibre ensembles as the shift parameter z becomes genuinely complex; the analogous phenomenon has been well known for eigenvalues. We use the superbosonization formula (Littelmann et al. in Comm Math Phys 283:343–395, 2008) in a regime where the main contribution comes from a three dimensional saddle manifold.
Bi-coherent states as generalized eigenstates of the position and the momentum operators
Authors: Bagarello F. , Gargano F. 
Published: May 2022

AbstractIn this paper, we show that the position and the derivative operators,$${{\hat{q}}}$$q^and$${{\hat{D}}}$$D^, can be treated as ladder operators connecting various vectors of two biorthonormal families,$${{{\mathcal {F}}}}_\varphi $$Fφand$${{{\mathcal {F}}}}_\psi $$Fψ. In particular, the vectors in$${{{\mathcal {F}}}}_\varphi $$Fφare essentially monomials inx,$$x^k$$xk, while those in$${{{\mathcal {F}}}}_\psi $$Fψare weak derivatives of the Dirac delta distribution,$$\delta ^{(m)}(x)$$δ(m)(x), times some normalization factor. We also show how bi-coherent states can be constructed for these$${{\hat{q}}}$$q^and$${{\hat{D}}}$$D^, both as convergent series of elements of$${{{\mathcal {F}}}}_\varphi $$Fφand$${{{\mathcal {F}}}}_\psi $$Fψ, or using two different displacement-like operators acting on the two vacua of the framework. Our approach generalizes well- known results for ordinary coherent states.
Platanic acid derived amides are more cytotoxic than their corresponding oximes
Authors: Kozubek Marie , Hoenke Sophie , Schmidt Theresa , Ströhl Dieter , Csuk René 
Published: May 2022

Abstract
Albeit platanic acid has been known since 1956, its potential to act as a valuable starting material for the synthesis of cytotoxic agents has been neglected for many years. Hereby we describe the synthesis of a small library of amides and oximes derived from 3-O-acetyl-platanic acid, and the results of their screening as cytotoxic agents for several human tumor cell lines. As a result, while the cytotoxicity of the oximes was diminished as compared to the parent amides, the homopiperazinyl amide 5 held the highest cytoxicity (EC50 = 0.9 μM for A375 human melanoma cells). Extra FACS and cell cycle measurements showed compound 5 to act onto A375 cells rather by apoptosis than by necrosis.

Die Impfaktion gegen Poliomyelitis in der DDR im Jahr 1960 am Beispiel der Stadt Halle (Saale): Historische Erfahrungen und Probleme
Authors: Wanke Anne Thordis , Bruns Florian 
Published: May 2022

ZusammenfassungIn den 1950er-Jahren stellte das epidemische Auftreten der spinalen Kinderlähmung (Poliomyelitis) die Gesundheitssysteme weltweit vor große Herausforderungen. Da eine kausale Therapie der Viruserkrankung nicht existierte, kam der Expositionsprophylaxe eine besondere Bedeutung zu. Letztlich gelang es erst durch die Entwicklung von Impfstoffen, die spinale Kinderlähmung nachhaltig zurückzudrängen. In der Deutschen Demokratischen Republik (DDR) wurde 1960 erstmals in Deutschland die Schluckimpfung nach Sabin-Tschumakow verabreicht, mit der binnen eines Jahres die nahezu vollständige Eradikation der spinalen Kinderlähmung in der DDR gelang. Der Artikel zeichnet anhand von unveröffentlichtem Archivmaterial die systematisch angelegte Impfaktion am Beispiel der damaligen Bezirkshauptstadt Halle (Saale) nach. Allein dort wurden im Mai 1960 innerhalb von 3 Tagen 63.328 Kinder und Jugendliche immunisiert. Bei 78.085 im Vorfeld erfassten Impflingen entsprach dies einer Quote innerhalb der poliovulnerablen Bevölkerungsgruppe von rund 81 %. Die Quellen zeigen, dass die staatliche Struktur des Gesundheitswesens der DDR und das Prinzip der aufsuchenden Impfung zum Erfolg der Impfaktion beitrugen.

Published: May 2022

ZusammenfassungAnlässlich eines richterlichen Gutachtenauftrages zur Frage, ob das Tragen von Mund-Nase-Schutzmasken zu einer Verfälschung des Atemalkoholmesswertes zuungunsten des Angeklagten führen kann, erfolgte unter Pandemiebedingungen eine experimentelle Testreihe an 6 gesunden Proband*innen (4 Männer, 2 Frauen), die risikoarmen Freizeitalkoholkonsum betrieben. Pro Untersuchungstag wurde jeweils ein Maskentyp (Op.-Maske, Textilmaske, FFP2-Maske) untersucht. Nach Aufnahme einer individuell berechneten Menge Alkohol und einer 30-minütigen Resorptionsphase erfolgten in halbstündigen Abständen 6 aufeinanderfolgende Atemalkoholmessungen, wobei zwischen den Messungen jeweils im Wechsel eine der Masken oder keine Maske getragen wurde. Anschließend wurden Wertepaare für Zeiträume mit und ohne Maske gebildet und die stündlichen Atemalkoholabbauraten berechnet. Im Ergebnis unterschieden sich die Atemalkoholabbauraten mit und ohne Masken nicht voneinander. Fehlermeldungen durch das Atemalkoholmessgerät, die auf das vorherige Tragen einer Maske zurückzuführen sind, traten nicht auf.

AbstractPrecision irrigation management requires operational monitoring of crop water status. However, there is still some controversy on how to account for crop water stress. To address this question, several physiological, several physiological metrics have been proposed, such as the leaf/stem water potentials, stomatal conductance, or sap flow. On the other hand, thermal remote sensing has been shown to be a promising tool for efficiently evaluating crop stress at adequate spatial and temporal scales, via the Crop Water Stress Index (CWSI), one of the most common indices used for assessing plant stress. CWSI relates the actual crop evapotranspiration ET (related to the canopy radiometric temperature) to the potential ET (or minimum crop temperature). However, remotely sensed surface temperature from satellite sensors includes a mixture of plant canopy and soil/substrate temperatures, while what is required for accurate crop stress detection is more related to canopy metrics, such as transpiration, as the latter one avoids the influence of soil/substrate in determining crop water status or stress. The Two-Source Energy Balance (TSEB) model is one of the most widely used and robust evapotranspiration model for remote sensing. It has the capability of partitioning ET into the crop transpiration and soil evaporation components, which is required for accurate crop water stress estimates. This study aims at evaluating different TSEB metrics related to its retrievals of actual ET, transpiration and stomatal conductance, to track crop water stress in a vineyard in California, part of the GRAPEX experiment. Four eddy covariance towers were deployed in a Variable Rate Irrigation system in a Merlot vineyard that was subject to different stress periods. In addition, root-zone soil moisture, stomatal conductance and leaf/stem water potential were collected as proxy for in situ crop water stress. Results showed that the most robust variable for tracking water stress was the TSEB derived leaf stomatal conductance, with the strongest correlation with both the measured root-zone soil moisture and stomatal conductance gas exchange measurements. In addition, these metrics showed a better ability in tracking stress when the observations are taken early after noon.

AbstractThe realization of compact high-power narrow-linewidth laser sources in the visible range has been a long-standing interest for the atomic physics community, especially in the field of laser cooling and trapping of alkaline-earth and alkaline-earth-like atoms. We report a simple master-slave injection-locked laser system capable of generating 500 mW at 460.86 nm with a linewidth of 1.6 MHz to realize magneto-optical trapping of strontium atoms on the $$5s^{2} \ ^{1}\mathrm {S}_{0}-5s5p \ ^{1}\mathrm {P}_{1}$$

The proposed system is also an effective solution for space-based experiments where a laser system’s size, weight, and electrical power consumption are crucial design parameters.
A new insight into pachychoroid diseases: Remodeling of choroidal vasculature
Authors: Kishi Shoji , Matsumoto Hidetaka 
Published: May 2022

Abstract
Purpose
Pachychoroid spectrum diseases are regarded as being different manifestations of a common pathogenic process. We suggest that pachychoroid diseases are consequences of chronic vortex vein stasis.

Methods
We describe how we came to this conclusion based on our own recent reports as well as a search of the related literature.

Results
Central serous chorioretinopathy (CSC) is the first stage of pachychoroid spectrum diseases. CSC is caused by congestion of choroidal veins, which are branches of the vortex veins. The venous outflow tract of the choroid is divided into four quadrants, based on horizontal and vertical watershed zones, with one or two vortex veins in each quadrant being independently responsible for venous outflow. In acute CSC, vortex vein stasis frequently causes asymmetric dilatation of the vortex veins in the horizontal watershed. The area of geographic filling delay in the choriocapillaris coincides with the area of this asymmetrically dilated vortex veins. With chronic stasis of the vortex veins, venous anastomosis occurs in the watershed zone as a means of compensating for the stasis, and the choriocapillaris becomes occluded in the area of filling delay. The anastomotic vessels dilate, becoming often hyperpermeable, and are then recognizable as pachyvessels. With the development of choriocapillaris ischemia, choroidal neovascularization (CNV) occurs at the site of pachyvessels. This is termed pachychoroid neovasculopathy (PNV). Polypoidal choroidal vasculopathy is regarded as a variant of PNV.

Conclusions
Intervortex venous anastomosis is among the key factors underlying the development of pachychoroid diseases. Remodeling of the venous drainage route though the anastomosis across the watershed zones is apparently a common response to chronic vortex vein stasis.
Lesion network mapping of mania using different normative connectomes
Authors: Cotovio Gonçalo , Faro Viana Francisco , Fox Michael D. , Oliveira-Maia Albino J. 
Published: May 2022

AbstractLesion network mapping is a neuroimaging technique that explores the network of regions functionally connected to lesions causing a common syndrome. The technique uses resting state functional connectivity from large databases of healthy individuals, i.e., connectomes, and has allowed for important insight into the potential network mechanisms underlying several neuropsychiatric disorders. However, concerns regarding reproducibility have arisen, that may be due to the use of different connectomes, with variable MRI acquisition parameters and preprocessing methods. Here, we tested the impact of using different connectomes on the results of lesion network mapping for mania. We found results were reliable and consistent independent of the connectome used.
