Gegenwärtiger Stand der Brillouin-Spektroskopie in der Ophthalmologie
Authors: Seiler Theo G. , Geerling Gerd 
Published: May 2023

Zusammenfassung
Hintergrund Die korneale Biomechanik hat einen erheblichen Einfluss auf das Ergebnis von hornhautchirurgischen Eingriffen, wie astigmatische Keratotomien, und kann Ursache für
Komplikationen, wie z. B. einer iatrogenen Keratektasie, sein. Bisherige Ansätze, die korneale Biomechanik und Spannungsverteilung in vivo zu bestimmen, um Komplikationen zu vermeiden und
Operationsergebnisse besser vorherzusagen, waren nicht erfolgreich.
Ziel der Arbeit In dieser Übersichtsarbeit soll die Funktionsweise der Brillouin-Spektroskopie erläutert und der gegenwärtige wissenschaftliche Stand der Technik für den Einsatz in
der Ophthalmologie dargelegt werden.
Methoden PubMed-Recherche relevanter experimenteller und klinischer Arbeiten sowie eigene Erfahrungen mit der Brillouin-Spektroskopie.
Ergebnisse Die Brillouin-Spektroskopie kann verschiedene biomechanische Moduli von okulären Geweben mit einer hohen räumlichen Auflösung bestimmen. Mit den derzeit verfügbaren
Geräten können an der Hornhaut fokale Schwächungen (Keratokonus) ebenso wie Versteifungen (nach Crosslinking) identifiziert werden. Auch die biomechanischen Eigenschaften der Linse können
gemessen werden. Die Anisotropie und Hydratation der Kornea ebenso wie die Winkelabhängigkeit des Laserstrahls während der Brillouin-Messung erschweren jedoch die Interpretation der
gemessenen Daten erheblich. Eine klare Überlegenheit in der Früherkennung von Keratektasien gegenüber der kornealen Tomografie konnte bisher noch nicht gezeigt werden.
Schlussfolgerung Die Brillouin-Spektroskopie ist eine neue Technik zur biomechanischen In-vivo-Charakterisierung von okulären Geweben, welche die bisherige diagnostische Lücke
schließen kann. Publizierte Ergebnisse sind vielsprechend, bis zum Einsatz im klinischen Alltag sind jedoch Verbesserungen der Messtechnik erforderlich, insbesondere hinsichtlich der
kornealen Anisotropie.
Synthesis of Heavy-Atom-Free Triplet Photosensitizers Based on Organoboron Complexes
Authors: Mula Soumyaditya , Koli Mrunesh 
Published: May 2023

AbstractA new class of organoboron complexes have been developed as heavy-atom-free triplet photosensitizers. A methodology was developed for the synthesis of an indolocarbazole–imine boron diﬂuoride (IIBD) dye and its dimer from a 6-formylindolocarbazole. The IIBD dye was then coupled with a BODIPY dye through the C-2 or C-8 position of the latter to synthesize two dyads. Both dyads showed superior photophysical properties to those of the IIBD dyes. The relative triplet conversion efficiencies of these dyes were determined by measuring their singlet-oxygen (1O2) generation capacities. All the synthesized dyes showed high 1O2 generation compared with the BODIPY dye PM567. The dyad linked through the C-2 position of the BODIPY core showed the highest 1O2 generation efficiency, which could be useful for photodynamic therapy of cancers.

Is the Doctor Who Cures Right? Or Should We Look for Black Swans? Complementary Aspects of Homeopathy's Scientific Identity
Authors: Rutten Lex 
Published: May 2023

AbstractPopper's point of view that a hypothesis can only be proven wrong by finding one counter-instance and that confirmation is unscientific is widely acknowledged. In medicine, however, we can only optimise the probability that a therapy works. For this we have to search for counter-instances for our existing ideas. The inclusion of a medicine in a repertory symptom-rubric when the symptom is seen in a cured case is wrong. This biased idea could be replaced by the Bayesian likelihood ratio (LR).LR can be assessed by prognostic factor research (PFR) using data collection by homeopathic practitioners. In the past 25 years, several PFR projects have been performed. It appeared that practitioners correct for biased entries in the repertory by finding practical solutions. Such solutions are keynote prescribing, selecting sub-rubrics that semantically confirm the preferred medicine and lowering threshold values for symptoms that confirm the preferred medicine. There is also variation between practitioners in confirming medicine selections by repertorisation. This way the bias of the repertory results in biased data collection. Statistical analysis of biased data results in biased conclusions.Research protocols should deal with bias in data collection and statistical analysis. Practitioners and researchers involved in data collection should be thoroughly trained. Incoming data should be monitored from the start resulting in adequate feedback to observers.
A global blockchain-based agro-food value chain to facilitate trade and sustainable blocks of healthy lives and food for all
Authors: Tyagi Kalpana 
Published: May 2023

AbstractThis article presents a holistic and integrated framework for blockchain deployment in global Agro-food ‘supply’ chains and how to transition them to accountable and sustainable global ‘value’ chains. Though many a scholarly contributions have assessed blockchain implementation at various levels in the chain, this research holistically looks at impediments to blockchain implementation at each level in the value chain. The study first establishes interlinkages between the three United Nations Sustainable Development Goals (SDGs), namely food for all (SDG 2), health for all (SDG 3), and sustainable consumption and production (SDG 12). It assesses the legal framework (namely trade law) and regulatory requirements therein. It then employs a case-study-based approach to assess blockchain deployment from the lens of operations management. These inter-disciplinary insights offer an enabling framework to successfully implement a vertically-integrated blockchain across the entire global Agro-food value chain. An end-to-end blockchain promises accountability, and thereby, enhanced trust in trade by offering a time-stamped ledger of transactions from the farm to the fork, to the end consumer. This systematic study, and its findings therein, are expected to serve as a ready reference guide to managers and policymakers for a truly integrated farm-to-fork blockchain deployment.

Azo dyes are valuable functional materials due to their sensitive response to and effective modulation of polarized light. It is essential to find out not only the optical anisotropy but also the complex refractive index of azo dye materials for photonics applications. We report here such measurements of highly ordered photoaligned azo dye films. The film has an apparent dichroic ratio of about 60. We model the photoaligned azo dye film systems using the Berreman transfer matrix. By means of regression fitting of the polarization dependent transmittance and reflectance data, we were able to determine the complex refractive indices of the aligned film at the wavelength range of 400–1000 nm. This material is found to have exceptionally large optical birefringence (Δn ∼ 0.75 at 632.5 nm and Δn ∼ 0.48 at 850.6 nm). The aligned azo dye film is valuable to applications such as coatable polarizers and optical modulation devices.

Published: May 2023

Abstract
In order to improve the comprehensive performance of the surface acoustic wave (SAW) temperature sensors and reduce clutter interference, the optimized Chebyshev window function, Blackman window function and Hamming window function are used to carry out the apodization weighting design for interdigital transducer (IDT) and reflective grating respectively. The influence of electrode apodization weighted structure on the performance of SAW temperature sensors is systematically studied through experiments. The results show that the apodization weighted design of IDT and reflective gate can effectively improve the resonance peak intensity and reduce the side lobe interference; the IDT and the reflection grating are designed with apodization weighting at the same time, compared with the single reflection grating weighting, the volatility of the side lobe of the Chebyshev window function and the Hamming window function increases, the volatility of the side lobe of the Blackman window function decreases; after electrode apodization optimization, the resonance frequency, Q value of the SAW sensor and the sensitivity to temperature increases; using a hamming window optimized electrode structure, the peak value of S11 is −36.73 dB and the Q value is 15 030. In order to ensure the signal processing ability and comprehensive performance of the sensor, an optimized Hamming window should be used for the electrode design of the SAW sensors.
In-situ measurement and close-loop control of atomic number density in an optically pumped magnetometer based on light absorption

Published: May 2023

Abstract
For optically pumped atomic magnetometers, the attenuation of the pumping light through the alkali-metal vapor due to light absorption is related to the number density of alkali-metal atoms. In this study, we propose an in-situ measurement and control method of atomic number density based on light absorption in the temperature range of 60 °C–160 °C, which is a much wider temperature range than considered in previous reports. A light absorption-density model is proposed to accurately describe the relationship between the light transmittance and the atomic number density. The influence of static and oscillating magnetic fields on the atomic number density measurement is also analyzed. Based on this model, a close-loop system is constructed to control the atomic number density using an electric heater. The experimental results exhibit that the proposed method can limit the fluctuation of the atomic number density in the range of 1.4%.
Multi-objective adaptive guided differential evaluation blind deconvolution and its application in bearing fault detection
Authors: Qin Limu , Yang Gang , Sun Qi , Lv Kun , Li Hengkui 
Published: May 2023

Abstract
Blind deconvolution (BD) methods applied to bearing fault detection often cause inferior performance due to inaccurate input parameters. Moreover, the optimal parameters of BD vary for different speeds and fault types of bearings, which seriously undermines the applicability of BD in practical industries. In this scenario, this paper proposes a parameter-adaptive BD method (MOBD) based on the multi-objective adaptive guided differential evaluation algorithm (MOAGDE). Firstly, based on the linear discriminant analysis, the quotient of inter-class distance and intra-class distance is used to determine the superiority of common bearing fault characteristic indicators to establish the multi-objective function of MOAGDE. Then, the optimal parameters of BD are searched by MOAGDE improved by dynamic switched crowding method (DSC-MOAGDE). Finally, the bearing is judged whether or what kind of fault has occurred according to the fault type locating index proposed in this paper. The main advantage of MOBD is that only bearing speed and type priories are required to achieve online detection of bearing faults. The results of simulation and experimental signals demonstrate that MOBD significantly outperforms the traditional BD method.
A fractional modeling approach of Buruli ulcer in Possum mammals
Authors: Farhan Muhammad , Shah Zahir , Jan Rashid , Islam Saeed 
Published: May 2023

AbstractBuruli ulcer is an increasingly common tropical disease that has been even ignored in advanced nations like Australia and Japan. Some mammals, including possums, have shown symptoms of the disease. Fractional derivatives are applied for a better understanding of biological processes and their crossover behavior. Infectious disease can be controlled by predicting the future spread while using Mathematical Models. Recently, various mathematical models based on classical integer-order and non-integer-order models have been proposed to predict the dynamics of infectious disease outbreaks. As a consequence, it is investigated the dynamics of the possum model using non-integer order derivatives in order to gain a better understanding and deeper insight into several biological models. The model’s important properties, such as the positivity of the model solution, equilibrium points, and the invariant property of the proposed model have also been discussed. The next-generation approach is used to compute the basic reproductive number0. Both the stability i.e. the local and global are obtained when0is less or greater than 1. The global stability of the fractional Possum model is achieved using the Lyapunov function in a fractional environment. Furthermore, The existence and uniqueness of the fractional order models are demonstrated. Numerical simulations of the model are done, along with their graphical representations, to examine the effects of arbitrary order derivatives and depict the implications of our theoretical results. It can be seen from the graphical findings that the fractional model provides more clarity and a better understanding.

Abstract
Titanium and titanium alloys have good comprehensive mechanical and physicochemical properties such as low density, high specific strength, good low-temperature performance, and non-magnetic properties, which have been widely used in aerospace, biomedical and other fields. In that article, numerical simulation of single-layer multi-pass different scanning paths for Ti-6Al-4V process by electron beam additive manufacturing via ANSYS finite element simulation software, and the isometric bi-directional reciprocal scanning method was proposed; the temperature curves with the time of key position points under different scanning paths were obtained, and the temperature change curves under different printing methods, and the deformation of the substrate after the additive manufacturing process were derived. After comparing the temperature accumulation and thermal stress deformation at critical points of the printed layer under three printing paths, the effect of the print path on the temperature change pattern was analyzed. What indicated to us is that the isometric bi-directional reciprocal scanning results have a better printing effect compared with the conventional printing method.
Numerical analysis for jet flow field on cleaning the outer wall of the double-layer injection needle
Authors: Zhang Peiqi , Li Dongmei 
Published: May 2023

Abstract
To avoid cross-contamination between different samples, improve the cleaning effect of the outer wall of the inner needle of the digital PCR detector, and reduce the cost of cleaning solution, the cleaning jet was simulated by FLUENT software using VOF gas-liquid two-phase flow model and PISO algorithm. In a certain range, the inlet velocity, cleaning solution viscosity, interfacial tension, and contact angle are changed to simulate the theoretical cleaning of the outer wall of the injection probe and the selection of various parameters under the best cleaning conditions is determined. The results show that the increase of inlet velocity has no significant effect on the increase of wall static pressure and the decrease of velocity increases; the increase of viscosity will greatly reduce the flow rate; higher interfacial tension requires higher inlet velocity to form a continuous jet; increasing the contact angle will not significantly reduce the static pressure and flow rate, and the residual sample is easier to clean. When the inlet velocity of 200mm /s is selected, the fluorine oil with a viscosity of 0.00124Paꞏs and interfacial tension of 16.2dyn/cm is used and the wall is coated with Teflon, the cleaning effect, and economy are excellent.
Spreading Characteristics of Volatile Liquid Film on the Liquid-solid Substrates
Authors: Yan Huan , Li Lincong , Chen Xue 
Published: May 2023

Abstract
The spreading characteristics of volatile liquid film on the liquid-solid substrate have been experimentally investigated. Unlike the liquid film spreading on the liquid substrate, there exists a dip at the top of the solid substrate, as a result, the spreading behaviors are inhibited. It is found that dip characteristics of R’/ R slightly decrease at the beginning then it keeps constant R’/ R=0.83 until the end. Moreover, the comparison of spreading behaviors on two different substrates is investigated. When the volatile film spreads on the liquid-solid substrate, the maximum radii of the outer and inner rings are smaller, but the process lasts longer. Although the evolutions of radii are different, the variation trend of nondimensional ring width is consistent. We further study the spreading rate; results show there exist three stages due to the relative importance of different forces. Our results provide important missing pieces to the rich mechanisms of the multiple-phase flow driven by the Marangoni effect.
Research on surface shape measurement of highly reflective surfaces based on stripe projection
Authors: Yuan Haisen 
Published: May 2023

Abstract
Metal workpieces with highly reflective surfaces are particularly common in modern industrial manufacturing systems, and their three-dimensional dimensional measurement has great applications and needs in various fields. Among the various three-dimensional dimensional measurement technologies, projection three-dimensional measurement technology is adopted for its non-contact, low-cost, high-precision, and fast data processing characteristics. However, because of the high reflectance of the highly reflective surface, the structured light photos taken by the camera will be overexposed and underexposed, which will lead to the lack of three-dimensional information obtained. Due to the large range of changes in surface reflectance and the limited grayscale range of the camera, the traditional stripe projection method cannot correctly measure the three-dimensional morphology of highly reflective surfaces [1]. This paper introduces an adaptive sinusoidal stripe grating based on the reflectance of the surface of an object, which is used to compensate for the overexposure of the camera when shooting on a highly reflective surface. Finally, the generated adaptive stripes are projected onto the measured object, and the phase solution and three-dimensional surface shape reconstruction are carried out by the heterodyne multi-frequency phase shift method.

Published: May 2023

Abstract
At present, the application of the traditional nondestructive testing technologies for hydrogen storage tanks is limited because of their requests to make the hydrogen storage tank to be out of service. The damage to the cylinder surface and some microstructures will change the echo-guided wave signal. However, there is no special cylinder detection probe now. In this paper, a probe of ultrasonic guided wave excitation generator is designed for vehicle-mounted winding hydrogen storage cylinders. The research results of this paper are of great significance for the safety of hydrogen storage tanks in new energy vehicles.

Published: May 2023

Abstract
Considering the alternation load of the high-clearance sprayer, the pesticide box is affected by transverse and longitudinal vibration. However, the shaped bracket of the pesticide box is important to machine elements, which mainly bear the load and have serious damage and high failure frequency. Therefore, the optimization design of the shaped bracket of the pesticide box of the high-clearance sprayer is given. In detail, a finite element analysis method is put forward. With the method, the change law of the stress-strain for the shaped bracket is discussed in different environmental loads. Then, the optimal parameter of the shaped bracket is explored in the case of ultimate load. The simulation results have important theoretical significance for improving the fatigue life of the shaped bracket and have practical significance for improving the vibration stability and safety of the high-clearance sprayer.
