SummarySeitdem Bundesgesundheitsminister Jens Spahn 2019 ein Rechtsgutachten zum Heilpraktikerrecht in Auftrag gegeben hat, geht eine Welle der Verunsicherung durch die Reihen der Heilpraktiker und Heilpraktikeranwärter. Werden wir jetzt abgeschafft, soll das Heilpraktikergesetz reformiert werden, wird die Ausbildung akademisiert – das sind nur einige der Spekulationen. Fest steht: Die Zeichen stehen auf Veränderung. In welcher Form und in welchem Ausmaß, ist bisher ungewiss. Ein Interview mit HP Elvira Bierbach und HP Christian Blumbach, dem Sprecherteam der Gesamtkonferenz der Heilpraktikerverbände und Fachgesellschaften.

Abstract
Background and study aims The TissueCypher Barrett’s Esophagus Assay is a novel tissue biomarker test, and has been validated to predict progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) in patients with Barrett’s esophagus (BE). The aim of this study was to evaluate the impact of TissueCypher on clinical decision-making in the management of BE.
Patients and methods TissueCypher was ordered for 60 patients with non-dysplastic (ND, n = 18) BE, indefinite for dysplasia (IND, n = 25), and low-grade dysplasia (LGD, n = 17). TissueCypher reports a risk class (low, intermediate or high) for progression to HGD or EAC within 5 years. The impact of the test results on BE management decisions was assessed.
Results Fifty-two of 60 patients were male, mean age 65.2 ± 11.8, and 43 of 60 had long segment BE. TissueCypher results impacted 55.0 % of management decisions. In 21.7 % of patients, the test upstaged the management approach, resulting in endoscopic eradication therapy (EET) or shorter surveillance interval. The test downstaged the management approach in 33.4 % of patients, leading to surveillance rather than EET. In the subset of patients whose management plan was changed, upstaging was associated with a high-risk TissueCypher result, and downstaging was associated with a low-risk result (P < 0.0001).
Conclusions TissueCypher was used as an adjunct to support a surveillance-only approach in 33.4 % of patients. Upstaging occurred in 21.7 % of patients, leading to therapeutic intervention or increased surveillance. These results indicate that the TissueCypher test may enable physicians to target EET for TissueCypher high-risk BE patients, while reducing unnecessary procedures in TissueCypher low-risk patients.

Abstract
Background and study aims The relationship between acute colonic diverticulitis and colorectal cancer (CRC) is unclear, but colonoscopy is recommended to exclude malignancy. We compared the detection rates for colorectal neoplasia in patients with colonic diverticulitis and asymptomatic patients who had positive fecal immunochemical tests (FITs).
Patients and methods In total, 282 patients with acute colonic diverticulitis were hospitalized in our hospital from February 2011 to December 2019. Of them, 143 patients with diverticulitis and 1819 with positive FITs patients during the same period underwent colonoscopy without a prior colonoscopy within 5 years. We retrospectively compared these patients in terms of the invasive CRC rate, advanced neoplasia detection rate (ANDR), adenoma detection rate (ADR), and polyp detection rate (PDR).
Results Compared to the diverticulitis group, the FIT-positive group had a significantly higher CRC rate (0 vs 2.7 %, P = 0.0061), ANDR (5.6 vs. 14.0 %, P = 0.0017), ADR (19.6 vs. 53.2 %, P < .0001), and PDR (44.1 vs. 91.0 %, P < .0001). Using 1:1 propensity score matching based on age and sex, we obtained 276 matched patients in both groups. After matching, no difference was found in the CRC rate (0 vs 0.7 %) or ANDR (5.8 vs 7.3 %) between groups, but the ADR and PDR were significantly higher in the FIT-positive group (20.3 vs 43.5 %, P < .0001; 45.7 % vs 86.2 %, P < .0001).
Conclusion Patients with acute diverticulitis had lower ADRs and PDRs than patients with positive FITs.

Digital Transfer for Hand Reconstruction in Cleft Hand and Foot Differences
Authors: Taghinia Amir H. , Taylor Erin M. , Winograd Jonathan , Labow Brian I. , Upton Joseph 
Published: February 2021

AbstractBackground Digital transfer for hand reconstruction in children with cleft hand and foot differences present unique challenges with anomalous anatomy and rare opportunities to dramatically improve function of one- or two-digit hands.Methods Medical records were reviewed for patients with cleft hand and foot treated at two pediatric institutions between 1996 and 2018. Hospital records, clinical photographs, radiographs, and alginate molds were available on all patients. Patient characteristics, indications for transfer, associated syndromes, donor and recipient anatomy, and complications were examined.Results Twenty digital transfers were identified in 16 patients. The mean age at time of transfer was 6 years (range: 3–18 years). Associated syndromes in this study included ectrodactyly ectodermal dysplasia clefting (EEC) syndrome and Goltz's syndrome. Recipient sites included the thumb (n = 17) and index ray (n = 3) in 10 hands with monodactyly, 6 hands with a two-digit ulnar syndactyly, and 3 hands with central deficiency and associated polydactyly or other anomalies. Donor sites included the great toe (n = 7), fifth toe (n = 9), great toe polydactyly (n = 2), thumb polydactyly (n = 1), and second toe (n = 1). All transfers survived. Revisions included tenolysis (n = 2), repeat fixation for nonunion or malunion (n = 2), and fusion for instability (n = 3).Conclusion Digital transfer in cleft hand and foot patients is a functional endeavor. The transferred digits provide sensation, mobility, and stability for opposition. Technically challenging due to small structures and atypical anatomy, these rare cases represent unique opportunities to improve function and appearance in the pediatric hand. This is a therapeutic study and reflects level of evidence IV.

Published: February 2021

The relativistic magnetron has a series of advantages, such as high efficiency, compact structure, and tunability. In this paper, an improved modified high-efficiency relativistic magnetron with a novel cathode endcap is presented and investigated numerically. In simulation, high-power microwave of the transverse electromagnetic mode is generated with an average power of 1.56 GW, frequency of 1.593 GHz, and power efficiency of 75.8% when the voltage is 586 kV and the current is 3.59 kA. Compared with a conventional cathode endcap, the novel cathode endcap has two advantages. First, the efficiency is increased from 56.4% to 75.8%. Second, the maximum electric field is reduced from 1.4 MV/cm to 1.0 MV/cm. The simulation results verify the validity of the novel cathode endcap.
Emergence of diauxie as an optimal growth strategy under resource allocation constraints in cellular metabolism
Authors: Salvy Pierre , Hatzimanikatis Vassily 
Published: February 2021

SignificanceWhen several sugars are at its disposition, the bacteriumEscherichia coliconsumes them in a specific order—a behavior called diauxie. We developed a framework combining dynamic methods and models of metabolism and gene expression to show that diauxie and its associated lag in cell growth can be explained simply as an optimal behavior under constraints on the protein amount and renewal in a cell. We validate our model by reproducing experimental results and successfully predict a diauxic behavior on a growth medium containing two types of sugar, glucose and lactose. Finally, we claim that the regulation mechanism inducing diauxie (thelacoperon) is a control system to implement growth optimality at the cellular level.
A tunable ultrasensitive plasmonic biosensor based on α-MoO3/graphene hybrid architecture
Authors: Wei Chenwei , Cao Tun 
Published: February 2021

Abstract
Two-dimensional (2D) materials attract wide attention due to their unique exciting physical properties, which offer new opportunities to design novel devices with enhanced or multiple functionalities. In particular, α-phase molybdenum trioxide (α-MoO3) is an emerging 2D material and exhibits strong anisotropic optical properties and low optical losses in the visible region, making it a promising candidate in tunable optical devices. Here, we proposed a tunable plasmonic biosensor based on α-MoO3/graphene hybrid architectures. By optimizing Au film thickness, the number of α-MoO3 layers and rotation angle, our proposed biosensor can achieve a high phase detection sensitivity of 1.5172 × 105 deg RIU−1 with a biosensor configuration of SF11 prism/47 nm Au/6-layer α-MoO3/monolayer graphene at the rotation angle ϕ = 60°. In addition, the proposed biosensor represents tunable phase detection sensitivity since α-MoO3 can act as a polarizer. Our approach offers a new direction in the development of tunable ultrasensitive plasmonic biosensors for label-free detection and ultralow-concentration analytes.

Published: February 2021

Abstract
Two-dimensional (2D) Dirac materials have attracted intense research efforts due to their promise for applications ranging from field-effect transistors and low-power electronics to fault-tolerant quantum computation. One key challenge is to fabricate 2D Dirac materials hosting Dirac electrons. Here, monolayer germanene is successfully fabricated on a Ag2Ge surface alloy. Scanning tunneling spectroscopy measurements revealed a linear energy dispersion relation. The latter was supported by density functional theory calculations. These results demonstrate that monolayer germanene can be realistically fabricated on a Ag2Ge surface alloy. The finding opens the door to exploration and study of 2D Dirac material physics and device applications.

Perturbation theory in the complex plane: exceptional points and where to find them
Authors: Marie Antoine , Burton Hugh G A , Loos Pierre-François 
Published: February 2021

Abstract
We explore the non-Hermitian extension of quantum chemistry in the complex plane and its link with perturbation theory. We observe that the physics of a quantum system is intimately connected to the position of complex-valued energy singularities, known as exceptional points. After presenting the fundamental concepts of non-Hermitian quantum chemistry in the complex plane, including the mean-field Hartree–Fock approximation and Rayleigh–Schrödinger perturbation theory, we provide a historical overview of the various research activities that have been performed on the physics of singularities. In particular, we highlight seminal work on the convergence behaviour of perturbative series obtained within Møller–Plesset perturbation theory, and its links with quantum phase transitions. We also discuss several resummation techniques (such as Padé and quadratic approximants) that can improve the overall accuracy of the Møller–Plesset perturbative series in both convergent and divergent cases. Each of these points is illustrated using the Hubbard dimer at half filling, which proves to be a versatile model for understanding the subtlety of analytically-continued perturbation theory in the complex plane.

Abstract

Objective. Adequate upper esophageal sphincter (UES) opening is essential during swallowing to enable clearance of material into the digestive system, and videofluoroscopy (VF) is the most commonly deployed instrumental examination for assessment of UES opening. High-resolution cervical auscultation (HRCA) has been shown to be an effective, portable and cost-efficient screening tool for dysphagia with strong capabilities in non-invasively and accurately approximating manual measurements of VF images. In this study, we aimed to examine whether the HRCA signals are correlated to the manually measured anterior–posterior (AP) distension of maximal UES opening from VF recordings, under the hypothesis that they would be strongly associated. Approach. We developed a standardized method to spatially measure the AP distension of maximal UES opening in 203 swallows VF recording from 27 patients referred for VF due to suspected dysphagia. Statistical analysis was conducted to compare the manually measured AP distension of maximal UES opening from lateral plane VF images and features extracted from two sets of HRCA signal segments: whole swallow segments and segments excluding all events other than the duration of UES is opening. Main results. HRCA signal features were significantly associated with the normalized AP distension of the maximal UES opening in the longer whole swallowing segments and the association became much stronger when analysis was performed solely during the duration of UES opening. Significance. This preliminary feasibility study demonstrated the potential value of HRCA signals features in approximating the objective measurements of maximal UES AP distension and paves the way of developing HRCA to non-invasively and accurately predict human spatial measurement of VF kinematic events.
Mitigation of multibeam stimulated Raman scattering with polychromatic light
Authors: Zhao Yao , Wu Charles F , Weng Suming , Sheng Zhengming , Zhu Jianqiang 
Published: February 2021

Abstract
A theoretical analysis is presented for the stimulated Raman scattering (SRS) driven by multiple beams with certain frequency differences or bandwidths. The concomitant electrostatic modes are excited by the scattering lights when the pump beams share a common electron plasma wave to drive SRS. This coupling can be suppressed when the frequency difference of the two beams is three times larger than the SRS growth rate of a single beam, where the beams develop their scattering lights independently. To mitigate SRS further under the multibeam irradiation, polychromatic pumps are introduced to reduce the SRS saturation level, where the weakly coupled common modes are heavily damped in hot plasmas. The sidescattering driven by polychromatic light in inhomogeneous plasmas is significantly reduced due to the wavevector mismatch of daughter waves. Particle-in-cell simulations confirm our theoretical analysis and demonstrate that the strength of multibeam SRS and the hot electron production in inhomogeneous plasmas can be controlled at a low level by polychromatic light with a few percentage bandwidth (

Time-of-flight mass spectrometry of aluminium plasma: investigation of multiply charged ions and clusters
Authors: Saxena Arvind Kumar , Singh R K , Joshi H C 
Published: February 2021

Abstract
Ionic species in laser-produced plasma plume are generally analyzed by the time-of-flight method using a charge collector placed near to the target surface. One of the shortcomings of these methods is sacrifice of the important information for large mass cluster ions and the different charge states of atomic ions. In the present manuscript, design, development, and optimization procedure of a modified Wiley–McLaren type time-of-flight mass spectrometer (TOFMS) for the diagnostics of ions and cluster distribution in laser produced plasma (LPP) plume is presented. Second harmonic (532 nm) from a pulsed Nd:YAG laser is used to ablate aluminium disk in a vacuum chamber evacuated to base pressure of 7 × 10−8 mbar. The mass spectrometric results of aluminium (Al) plasma are presented and discussed in detail. To minimize the degradation in detection and mass resolution of spectrometer due to the wide angular and energy spared of the ions in the plasma plume, optimization of the TOF spectrometer in different configurations, single as well as a double field, is also discussed. Cluster ions as large as

and multiply charged ions (MCI) up to Al11+ are observed in the mass spectra. The possible pathways for the production of MCI and cluster ions are discussed on the basis of the Coulomb explosion mechanism. The dependence of ion distribution on the laser fluence is also discussed.

Published: February 2021

Abstract
Quantum mechanics is compatible with scenarios where the relative order between two events can be indefinite. Here we show that two independent instances of a noisy process can behave as a perfect quantum communication channel when used in a coherent superposition of two alternative orders. This phenomenon occurs even if the original process has zero capacity to transmit quantum information. In contrast, perfect quantum communication does not occur when the message is sent directly from the sender to the receiver through a superposition of alternative paths, with an independent noise process acting on each path. The possibility of perfect quantum communication through independent noisy channels highlights a fundamental difference between the superposition of orders in time and the superposition of paths in space.

Abstract
The Transneptunian Automated Occultation Survey (TAOS II) is a blind occultation survey with the aim of measuring the size distribution of Trans-Neptunian Objects with diameters in the range of 0.3 ≲ D ≲ 30 km. TAOS II will observe as many as 10,000 stars at a cadence of 20 Hz with all three telescopes simultaneously. This will produce up to ∼20 billion photometric measurements per night, and as many as ∼6 trillion measurements per year, corresponding to over 70 million individual light curves. A very fast analysis pipeline for event detection and characterization is needed to handle this massive data set. The pipeline should be capable of real-time detection of events (within 24 hours of observations) for follow-up observations of any occultations by larger TNOs. In addition, the pipeline should be fast and scalable for large simulations where simulated events are added to the observed light curves to measure detection efficiency and biases in event characterization. Finally, the pipeline should provide estimates of the size of and distance to any occulting objects, including those with non-spherical shapes. This paper describes a new data analysis pipeline for the detection and characterization of occultation events.
