Das Implantat im kieferorthopädischen Kontext – die
Agenesie in der Frontzahnregion
Authors: Nikolaus Fürhauser , Rudolf Fürhauser 
Published: September 2022

AbstractAgenesien von bleibenden Zähnen werden mit einer Prävalenz von
bis zu 8% der Bevölkerung angegeben und Agenesien der lateralen
Schneidzähne sind am dritthäufigsten betroffen. Die wichtige
Frage für den behandelnden Kieferorthopäden ist, ob ein
Lückenschluss oder eine Lückenöffnung als
Therapiekonzept gewählt wird. Die Tendenz in der Literatur geht ganz
deutlich Richtung Lückenschluss, was bei Vorliegen einer Klasse
II-Relation oder bei Platzmangel als typische Option gewählt wird.
Jedoch entsteht der Eindruck, dass auch massive Zahnbewegungen mit Gefahr von
Wurzelresorptionen in Kauf genommen werden, um den Lückenschluss als
Vermeidung von prothetischer Versorgung umzusetzen. Aus historischer Sicht
betrachtet waren die Erfolgsraten und die ästhetischen Ergebnisse der
Prothetik nicht immer zufriedenstellend. Der vorliegende Artikel soll die
modernen und aktuellen Behandlungsoptionen zur Lückenversorgung vom
navigierten Implantat bis zur einflügeligen
Zirkonoxid-Klebebrücke darstellen. Das Thema der Milchzahnpersistenz im
Frontzahngebiet mit wird ebenfalls beleuchtet.
Unravelling the Chemotaxonomic Identity of “White” and “Black” Oregano (Origanum vulgare) in Northern Greece
Authors: Mertzanidis Dimitrios , Nakas Alexandros , Assimopoulou Andreana N. , Kokkini Stella 
Published: September 2022

AbstractThe two types of oregano used by the inhabitants of the villages of Μount Belles (GR1260001), the “white” oregano with white flowers and “black” oregano with purple flowers, were studied.
The two oregano types were collected from five localities along an altitudinal gradient from 217 m up to 1299 m. “White” oregano, was found in the three lowland regions (up to 752 m) where
the Pannonian-Balkanic turkey oak-sessile oak forest habitat (code 91M0) dominates. The “black” oregano was collected from the two higher altitudes, at 1177 m and 1299 m, where the
Asperulo-Fagetum beech forest habitat (9130) occurs. Measurements of the density and size of peltate glandular hairs (sessile glands) on calyces, bracts, and leaves suggest that
“white” oregano is distinguished by its conspicuous – apparently larger – glands. These differences were reflected in the total essential oil content, with the “white” oregano being much
richer (up to 4.3 mL/100 g dry weight) than the “black” (up to 0.6%). Striking differences have also been found in the volatile fraction of their essential oil composition. The “white”
oregano oils were characterized by the high content of carvacrol (up to 92.6% of identified peaks, by Headspace GC-MS). On the other hand, the two “black” oregano oils have a different
aromatic profile, first reported from Greece, with main components including the sesquiterpenes β-caryophyllene, D-germacrene, δ-cadinene and β-bisabolene. The results
so far indicate that “white” and “black” oregano, Origanum vulgare subsp. hirtum and subsp. vulgare respectively, can be clearly distinguished either by their
morphological (glandular) differences or by chemical (essential oil) composition.

Published: September 2022

AbstractThe unprecedented DAST-mediated (DAST = diethylaminosulfur trifluoride) deoxygenative fluorination of benzoyl-, TBDPS-, and Bn-protected 1-(β-d-4-thioarabinofuranosyl)uracil at the sugar portion was examined. Three kinds of nucleoside (Ns) products were formed: target thiolane Ns, ring-contracted thietane Ns, and anhydro Ns products. The reaction pathway was determined by the electronic effect of the protecting groups at the sugar and base moieties. The benzoylated uracil starting material gave the 2,2′-anhydronucleoside (anhydro Ns) as a major product, whereas the silylated and benzylated starting materials furnished the corresponding fluorinated products, in which the ring-contracted thietanes predominantly formed. The desired thiolane Ns could be obtained as major product by the addition of a pyridine derivative as an additive. Upon reacting N
3-benzoylated 1-(β-d-4-thioarabinofuranosyl)uracil with DAST in the presence of 2,4,6-collidine, the target 2′-deoxy-2′-β-fluoro-4′-thiouracil nucleoside could be obtained in 72% isolated yield along with the corresponding thietane Ns (7%) and anhydro Ns (3%) (thiolane Ns/thietane Ns/anhydro Ns = 10.3:1.00:0.43), with recovery of the starting material (12%). In this study, the first stereoselective synthesis of the β-anomer of 1-(2-deoxy-2-fluoro-4-thio-β-d-arabino-pentofuranosyl)cytosine (4′-thioFAC) has been developed.
Attitudes To and Uptake of Repertory Software in Homeopathy Clinical Practice—Results of an International Survey
Authors: Gray Alastair C. , Pracjek Parker , Straiges Denise 
Published: September 2022

Abstract
Background Despite the substantial size of the maturing complementary medicine (CM) industry, the technologies used by practitioners have received little research attention. In the clinical delivery of homeopathy services, repertory software can be employed to cross-reference client symptoms with numerous databases, making the process of seeking a clinical intervention quicker and more accurate. The purpose of the study is to learn about the quantitative patterns of usage, uptake and attitudes to repertory software amongst professional homeopaths.
Methods An online cross-sectional survey of 15 questions was completed by practicing professional homeopaths between August 2016 and May 2017, using non-probability snowball sampling. Questions gathered demographic information, reflections and attitudes on the use of electronic repertories in clinical homeopathy practice.
Results In total, 59% of respondents reported using software regularly in practice and 71% found that it adds clear value in their work. Sixty-eight percent of respondents learned about repertory software during homeopathy training, and 47% were introduced to software when they began clinical practice. Lack of sufficient training is a very important barrier to the use of repertory software, indicating that more robust and accessible software training is needed for practitioners. Many respondents agreed with a statement that repertory software represents good value for money and yet 46% agreed that it is cost prohibitive for most practitioners, signaling a challenge for software companies. Few respondents reported regularly using more than three of the most common repertory features.
Conclusion This preliminary study presents some potentially significant uptake, usage and attitude markers that stand to shed light on the practice of homeopathy and the place of emerging technologies such as repertory software. Ultimately, more research is needed to help identify and address the challenges, risks and tensions around integration of practice-enhancing technologies in CM educational and clinical settings to best serve the diverse and changing needs of practitioners.

The Joint European Torus (JET) is the only tokamak in the world able to operate in Deuterium–Tritium (DT) plasmas. A successful DT experimental campaign, the DTE2, has recently been carried out, providing unique opportunities for studying both physics and technological aspects. In particular, it allowed us to investigate and benchmark the solutions adopted to attenuate the significant 14 MeV neutron flux, needed to enable high-resolution gamma-ray spectroscopy measurements on a tokamak. While in inertial confinement experiments, gamma-rays and neutrons are discriminated through time-of-flight techniques; in magnetic confinement experiments, the neutron attenuators are a key element to allow gamma-ray measurements in order to reestablish the 1 × 105 to 1 background to signal ratio. In this paper, the role of the reference neutron attenuators at JET, based on LiH, has been analyzed and described.

Authors: Akis Esma , Gurses Emre , Aksoy Songul 
Published: September 2022

Objective
The purpose of this study was to investigate subjective vestibulo-spinal reflex test sensitivity in subjects with unilateral vestibular loss.

Method
Forty subjects diagnosed with UVL within 7 days of onset and 30 subjects without dizziness/balance disorder complaints were included in the study as the unilateral vestibular loss and control groups (70 subjects aged 18–60 years [mean: 42.95 ± 10.82]). Bithermal caloric test, Fukuda, Babinski Weil, tandem walking, and past pointing tests were performed. The subjective VSR tests’ sensitivities were compared among the various methods.

Results
The Fukuda test was determined to have the highest sensitivity value (65%; kappa coefficient: 0.352). The sensitivity values of the other tests, in descending order, are: Babinski Weil (55%, Kappa coefficient: 0.274), tandem walking (10%, Kappa coefficient: 0.022), and past pointing (2.5%, Kappa coefficient: −0.014). A positive moderate correlation was obtained between canal paresis asymmetry and Fukuda deviation degree (p = 0.009, r = 0.407). There was no correlation between Babinski Weil (p = 0.619), tandem walking (p = 0.538), and past pointing test results and canal paresis asymmetry (p > 0.05).

Conclusions
Fukuda and Babinski Weil tests can be used under conditions where all subjective tests are not performed because of limited time. However, these tests must be used alongside objective vestibular test batteries owing to their limited specificity and sensitivity.

Temperature and size modulation of the lattice thermal expansion on transition metallic nanostructures
Authors: Zhu Min , Liu Jin , Huang Qiang , Dong Jiansheng , Yang Xuexian 
Published: September 2022

Abstract
By combining the bond-order-length-strength theory, local bond average approach and core–shell model, a new analytical method for temperature- and size-dependent thermal expansion coefficient (TEC) of transition metallic nanostructures has been established. It shows that both cohesive energy and cubic Debye temperature are inversely proportional to the TEC in the crystalline materials, that both cohesive energy and Debye temperature decrease with the reduction in size, which leads to the size effect of TEC, and the bond nature parameter modulate the intensity of size-dependent TEC. In agreement with the measurements, the Debye temperature, rigidity factor and bond nature parameter for 12 kinds of transition metals were quantitatively obtained. The present new analytical method for thermal properties of transition metals is simple and accurate, which is beyond the scope of existing methods in thermal-modulation and -management of nano-photoelectronic devices.

Published: September 2022

Abstract
Ferroelectric transistors with semiconductors as the channel material and ferroelectrics as the gate insulator have potential applications in nanoelectronics. We report in-situ modulation of optoelectronic properties of MoSe2 thin flakes on ferroelectric 0.7PbMg1/3Nb2/3O3–0.3PbTiO3 (PMN-PT). Under the excitation of 638 nm laser, the photoresponsivity can be greatly boosted to 59.8 A W−1 and the detectivity to 3.2 × 1010 Jones, with the improvement rates of about 1500% and 450%, respectively. These results suggest hybrid structure photodetector of two-dimensional layered material and ferroelectric has great application prospects in photoelectric detector.

Authors: Sørensen Kasper , Søgaard Peter , Emerek Kasper , Schou Jensen Ask , Struijk Johannes Jan , Schmidt Samuel Emil 
Published: September 2022

Abstract

Objective. Conduction-induced heart failure in patients with left bundle branch block (LBBB) can benefit from cardiac resynchronization therapy (CRT). However, some patients are non-responders to the therapy with one contributing factor being poor optimization of the atrioventricular (AV) pacing delay. In this study, we have investigated the pacing-induced changes in the seismocardiogram (SCG). Approach. 14 patients with heart failure, LBBB, and CRT were included. SCG was recorded with pacing turned on and off. Based on a mean SCG heartbeat from each patient, fiducial points were annotated, and cardiac timing intervals (CTI) and amplitudes were derived. These were compared between the CRT group and a group of healthy normal subjects (n = 14). Echocardiography was also used to derive CTI. Intervals derived from the SCG and echocardiogram were correlated. Main results. The isovolumetric contraction time (IVCT) derived from SCG was significantly shorter in the CRT group when the pacemaker was turned on (63.2–52.6 ms, p = 0.027). The first peak-to-peak amplitude in the systolic complex was significantly larger with the pacemaker turned on (p = 0.002), as well as the ∣max-min∣ amplitude in the systolic complex (p = 0.003). Isovolumetric relaxation time and left ventricular ejection time (LVET) were not significantly different between pacemaker settings. Compared to normal subjects, IVCT was significantly prolonged with the pacemaker turned off. All amplitudes were significantly larger in the healthy subject group. IVCT and LVET derived from SCG were significantly correlated to the echocardiogram. Significance. IVCT shortened and SCG amplitudes increased in response to CRT, indicating a more efficient ventricular contraction. This demonstrates the possibility to detect cardio-mechanic changes in response to treatment with the SCG. However, for the patients the systolic part of the SCG was abnormal and difficult to characterize, raising concerns about the correct interpretation of the SCG.

Phase diagrams for two-component D-wave fermion superfluids with density imbalance
Authors: Zhang Lei , Wang Jibiao , Shang Xinle , Gao Yuan 
Published: September 2022

Abstract
Finite-temperature phase structures for asymmetric two-component D-wave fermion superfluids in the weak coupling BCS regime are investigated. The Fulde–Ferrell–Larkin-Ovchinnikov (FFLO) state becomes non-degenerate with the orientation of Cooper pair momentum due to the anisotropic pairing gap for D-wave pairing. The new parameter θ
0, corresponding to the orientation of Cooper pair momentum, greatly enriches the phase structures. Especially, the phase separation (PS) region in the phase diagram is significantly reduced comparing to that for S-wave pairing. Theoretically, the stability condition of solutions is equivalent to the positive definite Hessian matrix of free energy in the hyperplane defined by the number density constraints in the parameter space spanned by the average chemical potential μ, relative chemical potential h, paring gap Δ, pair momentum q, and θ
0. In addition, the stability condition of the superfluid density is essentially included in the positive definite Hessian matrix. Moreover, the positiveness of imbalance number susceptibility

Deep learning method for testing the cosmic distance duality relation*
Authors: Tang Li , Lin Hai-Nan , Liu Liang 
Published: September 2022

Abstract
The cosmic distance duality relation (DDR) is constrained by a combination of type-Ia supernovae (SNe Ia) and strong gravitational lensing (SGL) systems using the deep learning method. To make use of the full SGL data, we reconstruct the luminosity distance from SNe Ia up to the highest redshift of SGL using deep learning, and then, this luminosity distance is compared with the angular diameter distance obtained from SGL. Considering the influence of the lens mass profile, we constrain the possible violation of the DDR in three lens mass models. The results show that, in the singular isothermal sphere and extended power-law models, the DDR is violated at a high confidence level, with the violation parameter

and

, respectively. In the power-law model, however, the DDR is verified within a 1σ confidence level, with the violation parameter

. Our results demonstrate that the constraints on the DDR strongly depend on the lens mass models. Given a specific lens mass model, the DDR can be constrained at a precision of

Abstract
Two ways for producing a transport barrier through strong shear of the E × B poloidal flow have been investigated using GYSELA gyrokinetic simulations in a flux-driven regime. The first one uses an external poloidal momentum (i.e. vorticity) source that locally polarizes the plasma, and the second one enforces a locally steep density profile that also stabilizes the ion temperature gradient (ITG) instability modes linearly. Both cases show a very low local turbulent heat diffusivity coefficient

This behaviour is the result of a reduced turbulence intensity which strongly correlates with the shearing of turbulent structures as evidenced by a reduction of the auto-correlation length of potential fluctuations as well as an intensity reduction of the k

Published: September 2022

Abstract
Electric propulsion has advantages such as high maneuverability, good safety and reliability, being able to operate optimally with a control system. It is a future green technology which is environmentally friendly. The application of electric propulsion for ship is that the propeller is driven by using electric motor by regulating speed and/or torque. in this research, an permanent magnet synchronous motor (PMSM) is used to drive propeller of ship propulsion. The controller of proportional integral (PI) scheme is proposed to drive electric motor. The method of Ziegler Nichols stability margin tuning rule algorithm is performed to search the controller parameters. The optimal working point of propeller is determined by the cross intersection between the propeller loading curve to the coefficient of thrust curve of open water test propeller. The speed from the result of propeller working point analysis is set as control input reference. Based on the results of simulation, the proposed control of electric propulsion using PMSM motor is able to achieve the reference of speed.
