Gelenkkontrakturen – Behandlungsbeispiel zum Verbessern der Knieflexion
Authors: Schomacher Jochen 
Published: September 2023

ZusammenfassungBewegungseinschränkungen in Flexion im Kniegelenk sind häufig. Oft fehlen die letzten Bewegungsgrade nicht nur nach Operationen und Verletzungen, sondern auch aufgrund von Nichtgebrauch beispielsweise wegen Schmerz (Arthrose), oder wenn wir nicht mehr täglich in die tiefe Hocke gehen (Bequemlichkeit). Selbstmobilisation und Lagerung bieten eine einfache Abhilfe.
Defining Body Mass Index Using Weight and Length for Gestational Age in the Growth Assessment of Preterm Infants at Birth
Authors: Olsen Irene E. , Granger Marion , Masoud Waleed , Clark Reese H. , Ferguson A. Nicole 
Published: September 2023

Objective The objectives of this study were to describe (1) body mass indexes (BMIs) using weight and length for gestational age (GA) classifications, and (2) the additional information BMI, as a measure of body proportionality, provides for preterm infant growth assessment and care plans at birth.
Study Design Birth weight, length, and BMI of 188,646 preterm infants (24–36 weeks gestation) admitted to U.S. neonatal intensive care units (Pediatrix Clinical Data Warehouse, 2013–2018) were classified (Olsen curves) as small, appropriate, or large for GA (SGA < 10th, AGA 10–90th, LGA > 90th percentile for GA, respectively). The distribution for the 27 weight–length–BMI combinations was described.
Results At birth, most infants were appropriate for weight (80.0%), length (82.2%), head circumference (82.9%), and BMI (79.9%) for GA. Birth weight for GA identified approximately 20% of infants as SGA or LGA. Infants born SGA (or LGA) for both weight and length (“proportionate” in size) were usually appropriate for BMI (59.0% and 75.6%). BMI distinguished disproportionate weight for length in infants with SGA or LGA weight at birth (58.3%, 49.9%). BMI also identified 11.4% of AGA weight infants as small or large for BMI (“disproportionate” in size) at birth; only using weight for GA missed these underweight/overweight for length infants.
Conclusion The unique, additional information provided by birth BMI further informs individualized preterm infant growth assessment by providing an assessment of an infant's body proportionality (weight relative to its length) in addition to the routine assessment of weight, length, and head circumference for GA and may better inform care plans and impact outcomes.

Building the bioethics tools of a community council to the future: the ecosystemic gap
Authors: LeBlanc Antoine Boudreau 
Published: September 2023

AbstractThese are times of crisis. Recently, the COVID-19 pandemic and the resurgence of a form of Cold War raised international concerns about Health & Well-Being, Climate & Biodiversity, and Technology & Economy. Articulating bridges between disciplines, between cultures and between knowledges has never been more urgent to accelerate the translation of values and policies into actions. This comprehensive review argues for a radical ecosystemic approach to bridge the Medical & Environmental fields (studies, sectors, and technics) in an integrated management practice of Care, Production & Biodiversity. As bridging implies solving the epistemological gap, the argument emphasizes the need to raise awareness with theoretical hybridizations, fieldwork hypotheses, and working theories. According to Van Rensselaer Potter, who coined the term ‘bioethics’, awareness means to refocus the Medical & Environmental studies and surveillance processes from a target (e.g., the disease, the pathogen, or the resource) to its context (e.g., adding history, demography and ecology). Thus reframed, concerned researchers, leaders, and citizens should invest their effort in preparing the (contextual) terrain for ever-more organizational resilience. We conclude on the need for actions to shape the Health & Biodiversity determinants, to improve communication systems, data-sharing networks, and responsible innovations, and to foster knowledge translation to envision a better realistic future.“Ecology’s uneconomic, but with another kind of logic economy’s unecologic” (Potter 1988, p.9)

Authors: Pan Jiale , Wang Zhiyu , Yang Suijun , Ye Shuliang 
Published: September 2023

In this work, a vibrating capacitive sensor utilizing dual cantilever tuning fork resonance for electrostatic potential modulation was designed and fabricated. Initially, an electrostatic induction model was established, and the principle of non-contact electrostatic potential measurement was analyzed to identify the key factors influencing the sensor’s performance. Subsequently, the vibration mode of the tuning fork was simulated to determine the mechanical dimensions of the tuning fork and the driving frequency of the piezoelectric crystal. Additionally, the concept of enhancing the uniformity of the electric field near the sensor by employing a shield plate was proposed. Simultaneously, the optimal mechanical parameters of the shielding plate were determined through multi-physical field simulation to improve the sensor’s linearity. Finally, a compact calibration device was designed to measure the key performance parameters of the non-contact electrostatic potential sensor. The results demonstrate that the sensor has a measurement range of −10 to 10 kV, a measurement accuracy better than ±3%, and a linearity of 0.46%. This work offers an alternative solution for non-contact potential measurement.
A flexible P(VDF-TrFE)/MXene-based pressure sensor for breath and posture monitoring in football motion
Authors: He Mingjie 
Published: September 2023

Flexible capacitive pressure sensors are becoming increasingly significant in wearable electronic devices. The conventional form of pressure sensors, however, focuses primarily on microstructure design. While this approach can enhance sensitivity, it can also compromise the reliability of the sensor device. Here, we present a flexible pressure sensor according to the capacitance effect using the high dielectric P(VDF-TrFE)/MXene polymer as the capacitive pressure sensor dielectric layer. The P(VDF-TrFE)/MXene film has a high dielectric constant, making it an ideal choice for the dielectric layer of the flexible capacitive pressure sensor, resulting in rapid response and high sensing sensitivity. We also examine the impact of dielectric layer thickness on the sensor’s performance and find that increasing the thickness from 0.5 to 1.5 mm leads to a continuous improvement in sensitivity, reaching a maximum sensitivity of 0.42 kPa−1 and a wide sensing amplitude (3 Pa–25 kPa). Moreover, the response time of the capacitive pressure sensor can reach 47 ms. In addition, the sensor can be utilized to monitor human physiological information such as respiration and heartbeat. Its flexibility makes it ideal for application in sports, particularly for monitoring the movement posture of football players. Our findings can drive the wider adoption of pressure sensors in football motion monitoring.
A path integral molecular dynamics study on the muoniated xanthene-thione molecule
Authors: Kuwahata Kazuaki , Ito Shigekazu , Tachikawa Masanori 
Published: September 2023

A positive Mu is a useful tool for investigating the spin density of radical species. The theoretical estimation of its behavior in a molecule requires the inclusion of a quantum effect due to the small mass of muonium. Herein, we performed ab initio a path integral molecular dynamics (PIMD) simulation, which accurately included a multi-dimensional quantum effect, for muoniated 9H-xanthene-9-thione (μXT). Our results showed that the quantum effect significantly increased the hyperfine coupling constant (HFCC) value of μXT, which qualitatively improved the calculated HFCC value, compared to the experimental one. In the PIMD simulation, the bond length between muonium and sulfur in μXT is longer than that between hydrogen and sulfur in a hydrogenated 9H-xanthene-9-thione (HXT), leading to a spin density transfer from XT (9H-xanthene-9-thione) to muonium due to neutral dissociations. Additionally, we found that the S–Mu bond in μXT prefers a structure perpendicular to the molecular plane, where the interaction between Mu and the singly occupied molecular orbital of μXT is the strongest. These structural changes resulted in a larger HFCC value in the PIMD simulation of μXT.

Authors: Tanisa N. Y. , Alam khan Md Kamrul , Salahuddin M. 
Published: September 2023

Silver nanoparticles (Ag NPs) were manufactured utilizing Pathor Kuchi Leaf (PKL) extract in an environmentally, cost-effective green way. X-Ray Powder Diffraction (XRD), Fourier Transform Infrared (FTIR), Ultraviolet–Visible Spectroscopy (UV–Vis), and Scanning Electron Microscopy (SEM) have been used to look into Ag NPs generation. The crystalline structure was shown by the XRD pattern investigation, and its typical size is 19 nm. Its biological molecules composites are in charge of the diminishment and also the capping of Ag NPs, according to FTIR spectra. The UV–Vis spectra of silver NPs expressed a noticeably large absorption peak centered at ∼400 nm, which denoted the production of Ag0 from Ag+. After the distribution of sizes analysis, it must have been discovered that the mean dimension of the particles of the spherical silver nanoparticles in the SEM pictures was 5.33 µm. Ag NPs have been shown to potentially improve the power generation, short circuit current, and open circuit voltage of PKL bio-electrochemical cells. This work exhibits a straightforward, economical, and ecologically friendly way of manufacturing. The uniqueness of this work is that it is the first-ever comparative analysis of Ag NPs’ production utilizing PKL extract. The majority of the conclusions have been grouped and visually explained.

Authors: Duarte Isabel Margarida , Marques Maria Aldina 
Published: September 2023

Abstract
This chapter aims to highlight some uses of pronominal
address forms (
tu, você, vocês
and

vós
[‘you’ sg+pl]) in European Portuguese
and compare them to Brazilian Portuguese, based on speakers’ perceptions
which express their pragmatic awareness. The data were collected on the
internet, from Facebook posts. An online linguistic survey on this matter
was conducted to complement the data. Some examples were also collected from
public speeches covering various discourse genres. Our findings show that
(i) the speakers have highly varied metalinguistic and metapragmatic
knowledge regarding the uses of the pronominal address systems in both
varieties, (ii) knowledge of the language is supported by opinions and
beliefs that value the central notion of social prestige related to a
standard variety.
Hybrid agreement in polite address
Authors: Gaglia Sascha 
Published: September 2023

Abstract
This chapter examines ‘hybrid agreement’ in polite
address in the Romance languages. This term usually describes a two-way
agreement pattern and presents a major challenge to syntactic theories due
to the apparent formal mismatches that occur, for example, in French

Vous êtes loyal
‘You are loyal’, where the
polite address pronoun vous and the predicate

êtes
are both plural, while the
predicative adjective loyal is singular. Similarly, Modern
Italian shows a gender conflict between the female politeness pronoun

lei
and the predicative adjective when the
addressee is male, e.g.,
Lei è
generoso
‘You are generous’. While Pollard
and Sag (1994) and Wechsler (2011)
assume double feature sets for solving mismatches of this sort, I propose an
analysis including single feature sets and a syntactic politeness feature in
the classical version of Lexical-Functional Grammar. Synchronic as well as
diachronic evidence is supplied from a contrastive perspective on French,
Italian, Peninsular Spanish, and Chilean Spanish.
Address and politeness
Authors: Vismans Roel 
Published: September 2023

Abstract
This chapter sets out to explore the theoretical
relationship between address and politeness. It explores the nature of
address and discusses the concept of “address theory”, the need for such a
theory, and what it should encompass. It analyses, for the first time, the
theoretical contrasts between address and politeness by means of a
chronological discussion of politeness theory and its treatment of address,
as well as a critical discussion of the handling of politeness theory by the
address literature. It concludes, with Terkourafi (2005), that each of the approaches to politeness
surveyed has its merits, and observes that, despite frequent references to
politeness, the address literature engages in reflection on politeness
(theory) only sporadically. It also calls for a debate about the need for a
(separate) address theory, including the continued use of the labels T and
V, which is widespread in both address research and politeness research.
Development of a piston-actuated 3D bio-printer with performance prediction system for the reliable printing of tubular structures
Authors: Liu Kun , Yang Chenghao , Li Jinmin , Ling Gang , Xiong Shaoping 
Published: September 2023

Abstract
3D bio-printing is a promising approach for creating tubular structures within the human body by precisely controlling the distribution of cells. While several 3D bio-printers have been developed for printing tubular structures, achieving reliable and repeatable construction of effective human tubular structures remains a challenge. This paper presents a piston-actuated 3D bio-tubular structures printer that uses a rotary rod-support printing method and a printing performance prediction system. The printing performance prediction system is based on a two-phase flow computational fluid dynamics model that simulates the tubular structure forming process and provides optimal printing setup parameters, such as extrusion nozzle movement speed, nozzle height, and rod rotating speed. Experimental testing has validated the performance prediction system, which achieved a fair prediction accuracy with an average error of around 10%. The proposed bio-printer and prediction system have the potential to improve the efficiency and effectiveness of tubular structure printing for various biomedical applications.
The Faddeev and Schrödinger approaches to Efimov states—a numerical comparison
Authors: Tempest Kajsa-My , Jonsell Svante 
Published: September 2023

Abstract
We compare effective hyperradial three-body potentials calculated using the S-wave part of the Faddeev equations to calculations using the full Schrödinger equation. As two-body model potential we test both a short-range potential and a Lennard-Jones potential with van der Waals tail. In the former case we find excellent agreement between the two methods for the lowest adiabatic state, indicating that the Faddeev method can be a useful tool also for numerical computations. For excited states the two methods show important differences, but agree for hyperradii larger than about five times the range of the potential (independent of the value of the scattering length and of the number of bound states). For the van der Waals potential, we focus on how well the Faddeev method reproduces the so-called van der Waals universality. We find that indeed the universality is manifest also using this method, but at a slightly different value of the universal parameter

D2 hyperfine excitations for zero-velocity atoms. Effects due to the selection of different atomic velocity classes in this preparation step are responsible for the presence of several satellite lines that can be found in the fluorescence decay spectra of both 85Rb and 87Rb. Compared to the main lines, these satellites do not show a strong dependence on the relative linear polarization directions of the lasers used in the preparation and the electric quadrupole steps. The relative intensities of the satellites decrease as the intensity of the preparation laser increases. Results of a rate equation calculation that explicitly includes selection-of-velocity effects indicate that optical pumping plays a central role in determining the relative intensities and the polarization dependence of the satellite lines.

Thermal dissipation of the quantum spin Hall edge states in HgTe/CdTe quantum well
Authors: Fang Jing-Yun , Zhuang Yu-Chen , Guo Ai-Min , Sun Qing-Feng 
Published: September 2023

Abstract
Quantum spin Hall effect is characterized by topologically protected helical edge states. Here we study the thermal dissipation of helical edge states by considering two types of dissipation sources. The results show that the helical edge states are dissipationless for normal dissipation sources with or without Rashba spin–orbit coupling in the system, but they are dissipative for spin dissipation sources. Further studies on the energy distribution show that electrons with spin-up and spin-down are both in their own equilibrium without dissipation sources. Spin dissipation sources can couple the two subsystems together to induce voltage drop and non-equilibrium distribution, leading to thermal dissipation, while normal dissipation sources cannot. With the increase of thermal dissipation, the subsystems of electrons with spin-up and spin-down evolve from non-equilibrium finally to mutual equilibrium. In addition, the effects of disorder on thermal dissipation are also discussed. Our work provides clues to reduce thermal dissipation in the quantum spin Hall systems.
Geomagnetic reference map super-resolution using convolutional neural network
Authors: Ma Xiaoyu , Zhang Jinsheng , Li Ting 
Published: September 2023

Abstract
Geomagnetic matching navigation technology, as an important assisted navigation method, has gradually been wildly used in the navigation field, in which the quality of geomagnetic reference map is of great significance on improving the guidance and positioning accuracy. However, the existing geomagnetic reference map reconstruction methods can hardly satisfy the actual needs. Considering the popularity of deep learning methods in the image super-resolution (SR) field, a geomagnetic reference map SR method using a convolution neural network is proposed. First, rectangular harmonic analysis theory is used to construct the training dataset, which is based on data from the United States Geological Survey and the International Geomagnetic Reference Field. Then, a multi-channel convolutional neural network, which integrates all the three independent components in the geomagnetic reference field, is proposed of reference map SR reconstruction. Experimental results show the effectiveness of our proposed method over other state-of-the-art methods.
Sphericity measurement based on telecentric imaging mechanism with image distortion correction and eccentricity error compensation
Authors: Huang Jingzhi , Lian Dongshan , Yang Runze , Liu Yongmeng , Tan Jiubin 
Published: September 2023

Abstract
Sphericity is an essential geometric parameter for determining the processing manufacturing quality of spherical components. This study presents a sphericity measurement method based on telecentric imaging mechanism with image distortion correction and eccentricity error compensation. A sphericity measurement system is designed, and the projection images of the cross-section on the equatorial plane of the measured sphere are acquired using a line scan camera with bilateral telecentric lenses. An analytical camera model for this sphericity measurement system is established by considering major sources of image distortion. The subpixel edge points of the projection images are extracted and converted to cross-sectional profiles on the equatorial plane according to the camera model. An eccentricity error compensation strategy for contour matching of the obtained cross-sectional profile on the equatorial plane is also developed to obtain the three-dimensional contour point coordinates of the sphere. Sphericity is then calculated according to the least square criterion. The effectiveness of the proposed method is verified by measuring two steel balls with diameter in 20 mm and 30 mm. The sphericity measurement error is reduced by 0.3383 mm and 0.4653 mm respectively after image distortion correction and is reduced by 0.2268 mm and 0.0795 mm respectively after eccentricity error compensation. The proposed method can be extended to form error measurements for opaque components with rotary structure on the outer contour.

Published: September 2023

Abstract
Highly stable and environmentally friendly nitrogen-doped graphite quantum dots consisting of ∼12 layers of graphene, average diameter of ∼7.3 nm, prepared by atmospheric pressure microplasma are reported to have blue emission due to surface states created by nitrogen doping (9 atomic%) and reaction with oxygen. The low-temperature synthesis method requires simple precursors in water, with no annealing or filtration, producing crystalline disc-shaped quantum dots with ∼68% photoluminescence emission quantum yield at 420 nm excitation and that have shown stability for more than one month after the synthesis. The nitrogen doping in the quantum dots mainly occurs in graphitic core as substituted type of doping (63–67 atomic%) and the amount of doping is sufficient to create emissive states without impacting the core structure. The optical and chemical properties do not undergo serious retardation even with re-dispersion suggesting easy applicability for cellular imaging or optoelectronics.
Some existence results for the Brinkman-Fourier system
Authors: Zuo Bijun 
Published: September 2023

Abstract
In this paper, we prove the existence of weak solutions to the Brinkman-Fourier system under suitable conditions on the pressure. The main novelty of this paper lies in the fact that the viscosity and heat conductivity coefficients are functions of the temperature, furthermore, the viscosity coefficients may be degenerate in the sense that it may vanish as the temperature goes to zero. The key points to achieve the main results rely on the Galerkin method, the De Giorgi method and some compactness arguments.
