Kinematic model calibration of a collaborative redundant robot using a closed kinematic chain
Authors: Petrič Tadej , Žlajpah Leon 
Published: October 2023

AbstractIn this paper, we propose a novel approach for the kinematic calibration of collaborative redundat robots, focusing on improving their precision using a cost-effective and efficient method. We exploit the redundancy of the closed-loop kinematic chain by utilizing a spherical joint, enabling precise definition of the robot end-effector position while maintaining free joint motion in the null space. Leveraging the availability of joint torque sensors in most collaborative robots, we employ a kinesthetic approach to obtain constrained joint motion for calibration. An optimization approach is utilized to determine the optimal kinematic parameters based on measured joint positions and a constrained end-effector position defined by the spherical joint. The effectiveness of the proposed method is demonstrated and validated on the Franka Emika Panda robot, a 7-DoF robot. Results indicate a significant enhancement in absolute accuracy, with comparable performance to more expensive sensor systems such as optical measurement systems. Our approach offers a practical and cost-effective solution for improving the precision of collaborative robots.
Genes possibly related to symbiosis in early life stages of Acropora tenuis inoculated with Symbiodinium microadriaticum

Published: October 2023

AbstractDue to the ecological importance of mutualism between reef-building corals and symbiotic algae (Family Symbiodiniaceae), various transcriptomic studies on coral-algal symbiosis have been performed; however, molecular mechanisms, especially genes essential to initiate and maintain these symbioses remain unknown. We investigated transcriptomic responses of Acropora tenuis to inoculation with the native algal symbiont, Symbiodinium microadriaticum, during early life stages, and identified possible symbiosis-related genes. Genes involved in immune regulation, protection against oxidative stress, and metabolic interactions between partners are particularly important for symbiosis during Acropora early life stages. In addition, molecular phylogenetic analysis revealed that some possible symbiosis-related genes originated by gene duplication in the Acropora lineage, suggesting that gene duplication may have been the driving force to establish stable mutualism in Acropora, and that symbiotic molecular mechanisms may vary among coral lineages.
Generation of DNA oligomers with similar chemical kinetics via in-silico optimization
Authors: Tobiason Michael , Yurke Bernard , Hughes William L. 
Published: October 2023

AbstractNetworks of interacting DNA oligomers are useful for applications such as biomarker detection, targeted drug delivery, information storage, and photonic information processing. However, differences in the chemical kinetics of hybridization reactions, referred to as kinetic dispersion, can be problematic for some applications. Here, it is found that limiting unnecessary stretches of Watson-Crick base pairing, referred to as unnecessary duplexes, can yield exceptionally low kinetic dispersions. Hybridization kinetics can be affected by unnecessary intra-oligomer duplexes containing only 2 base-pairs, and such duplexes explain up to 94% of previously reported kinetic dispersion. As a general design rule, it is recommended that unnecessary intra-oligomer duplexes larger than 2 base-pairs and unnecessary inter-oligomer duplexes larger than 7 base-pairs be avoided. Unnecessary duplexes typically scale exponentially with network size, and nearly all networks contain unnecessary duplexes substantial enough to affect hybridization kinetics. A new method for generating networks which utilizes in-silico optimization to mitigate unnecessary duplexes is proposed and demonstrated to reduce in-vitro kinetic dispersions as much as 96%. The limitations of the new design rule and generation method are evaluated in-silico by creating new oligomers for several designs, including three previously programmed reactions and one previously engineered structure.
General construction scheme for geometrically nontrivial flat band models
Authors: Kim Hyeongseop , Oh Chang-geun , Rhim Jun-Won 
Published: October 2023

AbstractA singular flat band (SFB), a distinct class of the flat band, has been shown to exhibit various intriguing material properties characterized by the quantum distance. We present a general construction scheme for a tight-binding model hosting an SFB, where the quantum distance profile can be controlled. We first introduce how to build a compact localized state (CLS), endowing the flat band with a band-touching point and a specific value of the maximum quantum distance. Then, we develop a scheme designing a tight-binding Hamiltonian hosting an SFB starting from the obtained CLS, with the desired hopping range and symmetries. We propose several simple SFB models on the square and kagome lattices. Finally, we establish a bulk-boundary correspondence between the maximum quantum distance and the boundary modes for the open boundary condition, which can be used to detect the quantum distance via the electronic structure of the boundary states.
Single-ended recovery of optical fiber transmission matrices using neural networks

Published: October 2023

AbstractUltra-thin multimode optical fiber imaging promises next-generation medical endoscopes reaching high image resolution for deep tissues. However, current technology suffers from severe optical distortion, as the fiber’s calibration is sensitive to bending and temperature and thus requires in vivo re-measurement with access to a single end only. We present a neural network (NN)-based approach to reconstruct the fiber’s transmission matrix (TM) based on multi-wavelength reflection-mode measurements. We train two different NN architectures via a custom loss function insensitive to global phase-degeneracy: a fully connected NN and convolutional U-Net. We reconstruct the 64 × 64 complex-valued fiber TMs through a simulated single-ended optical fiber with ≤ 4% error and cross-validate on experimentally measured TMs, demonstrating both wide-field and confocal scanning image reconstruction with small error. Our TM recovery approach is 4500 times faster, is more robust to fiber perturbation during characterization, and operates with non-square TMs.

Authors: Szynkiewicz Sarah H. , Drulia Teresa , Griffin Lindsay , Mulheren Rachel , Murray Kelsey L. , Lee Theresa , Kamarunas Erin 
Published: October 2023

Objective:
The objective of this study was to determine the effect of intensity dosing during tongue exercise on tongue pressure generation, adherence, and perceived effort.

Design:
This was a five-site, prospective, randomized clinical trial. Outcome measures were obtained across multiple baselines, biweekly during exercise, and 4-weeks post-intervention.

Setting:
The general community at each study site.

Participants:
Typically aging adults between 55–82 years of age with no history of neurological or swallowing disorders. Eighty-four volunteers completed the study.

Interventions:
Participants were randomly assigned to one of four exercise groups: (a) maximum intensity/no biofeedback, (b) progressive intensity/no biofeedback, (c) maximum intensity/biofeedback, and (d) progressive intensity/biofeedback. Half of the participants completed a maintenance exercise program.

Outcome Measures:
Maximum isometric pressure (MIP), regular effort saliva swallow pressure, adherence, and the Borg Rating of Perceived Exertion Scale.

Results:

All exercise protocols were efficacious for gains in MIP (large effect sizes; Cohen's
d
). Group 3 made gains in regular effort saliva swallow pressure (medium effect size). There was a significant change in perceived exertion for regular effort saliva swallow pressure at 8 weeks. Tongue pressure gains were maintained at 1 month, regardless of maintenance group status. Mean adherence across groups was high.

Conclusions:
All groups improved pressure generation. Intensity dosing differences did not affect strength gains, adherence, or detraining. Regular effort saliva swallow pressure may be most responsive to maximum intensity with biofeedback. The findings suggest flexibility in approach to tongue exercise protocols. Tongue muscles may differ from limb muscles in terms of dose response and neuroplasticity principles.
Tri‐layer low‐carbon distributed optimization of integrated energy systems based on hybrid games under stochastic scenarios

Published: October 2023

AbstractThe low‐carbon development of integrated energy systems is achieved via the sharing of multiple energy interactions by park‐level IES (PIES).However, coordinating profit distribution conflicts among complex interactive stakeholders in stochastic scenarios is challenging. Accordingly, this study proposes a novel tri‐layer framework that aggregates different game mechanisms to investigate the interactions between PIESs and coupled energy markets. First, a linkage trading mechanism is proposed by integrating carbon emissions trading and green certificate trading, which establishes a coupled electricity‐carbon‐green certificate market. Consequently, a park aggregation operator acts as an intermediary between PIESs and the coupled market, setting upper‐level purchase and sale prices to guide unit generation in each PIES using the Stackelberg game theory. Subsequently, the Nash game theory is applied to realize cooperative bargaining among PIESs for a fair revenue distribution. Further, the impact of uncertain environments is considered by utilizing stochastic scenario methods and the conditional value‐at‐risk theory. To protect the privacy of each participating agent while improving the convergence speed, a differential evolutionary method is combined with analysis target cascading to solve the framework. Finally, the proposed scheduling method is validated by utilizing a typical case to optimize conflicting PIES interests in multiple scenarios and realize decarbonisation.
Adaptive inertia and damping of grid‐connected inverter with improved VSG control
Authors: Ling Zhitao , Liu Yitao , Wang Zhiping , Yin Jian 
Published: October 2023

AbstractThe control technology of virtual synchronization generator (VSG) based on energy storage system is proposed to compensate for the inertia and damping loss caused by the grid connection of distributed generators. However, with the addition of virtual inertia and damping, VSG is prone to generate frequency and power oscillation, and the regulating ability is weakened. For the above problems, this paper analyzes the inertia and damping characteristics of the synchronous motor in the rotation of synchronous motors, and applies artificial neural network control to VSG. In intelligent control strategy, a multi‐input‐output radial basis function (RBF) neural network is first proposed to adaptively adjust virtual inertia and damping. Finally, an experimental platform with a rated power of 1 kW and a variable load of 1 kW was built to validate the proposed control strategy. The experimental results show that the artificial neural network control strategy has a better regulation ability.

Context. Blazars are the most numerous class of very-high-energy (VHE; E > 100 GeV) gamma-ray emitters. At present, measured redshifts are available only for about 80% of the VHE gamma-ray sources; this is mainly due to the difficulty in measuring reliable redshifts from their nearly featureless continuum optical spectra.
Aims. As the VHE sky is still vastly unexplored, VHE blazars are unique objects. High-energy spectra from blazars are used for extragalactic background light studies, to investigate topics related to cosmology or fundamental physics, and to find the source luminosity. This allows one to study the properties of the host galaxy, its black hole, and the gamma-ray emission mechanisms. All of these studies require suitable estimations of the blazar distance, which has motivated the use of novel approaches when measuring the redshift of faint optical lines in their spectra is very uncertain.
Methods. We present the new optical spectroscopic observations of S5 0716+714 and its environment taken on December 20, 2019, with the Gemini GMOS North telescope.
Results. We do not find any absorption lines in the blazar spectrum; however, we were able to get the redshifts of 21 other galaxies in the field, 15 of which form a group at z = 0.2304 ± 0.0013. Performing a population study of galaxies, we found that S5 0716+714 belongs to this group with a probability > 99%.

Nanoporous metallic networks: Growth process and optical properties
Authors: Hamode Mohamed , Ron Racheli , Krause Alon , Salomon Adi 
Published: October 2023

Nanoporous metallic systems exhibit a new generation of advanced materials with potential in a wide variety of technological fields among them catalysis, photonics, optoelectronics and sensors.Their high surface-to-volume ratio, multimodal nanoscale moieties, ability to host guest materials, and inhomogeneous surface at the submicron scale distinct them from both bulk metals and conventional plasmonic materials as well as meta-surfaces. Those structures can be prepared through different fabrication and synthesis strategies including chemical dealloying, assembly of pre-synthesized metallic nanoparticles, and via templating. In a sharp contrast with these preparation strategies, we have demonstrated one can fabricate a macroscopic nanopourus metallic networks by using physical vapor deposition in a short single-step process. These materials are highly pure, and they show very unique linear and non-linear optical properties, among them high Second-Harmonic-generation response.
Herein, we will discuss their growth process mechanism, and utilize it for more complex 3d structure which behave as SHG reflectors.
Diagnostik und Therapie der Osteoporose
Authors: Maus Uwe , Bühring Björn 
Published: October 2023

ZUSAMMENFASSUNGOsteoporose ist eine systemische Erkrankung und gekennzeichnet durch eine Verringerung der Knochenmineralisation und Verschlechterung der Knochenstruktur. Sie führt zu einem zunehmenden Risiko für osteoporotische Frakturen, vor allem an der Wirbelsäule, dem proximalen Femur, am Becken, dem proximalen Humerus und dem distalen Unterarm. Der Dachverband der deutschsprachigen osteologischen Gesellschaften, DVO, veröffentlicht in regelmäßigen Abständen aktualisierte Versionen der Leitlinie zur Diagnostik und Therapie der Osteoporose. In dem vorliegenden Beitrag sollen die wesentlichsten Inhalte der Leitlinie und die Neuerungen dargestellt werden. Die wichtigsten Neuerungen sind die Überarbeitung der Risikofaktoren für eine Osteoporose, einschließlich der dazugehörigen Risikogradienten, die Änderungen der Vorhersagezeiträume des bisher verwendeten 10-Jahres-Frakturrisiko auf einen 3-Jahres-Zeitraum und die Einführung von neuen Therapieschwellen zur Indikationsstellung für eine spezifische medikamentöse Therapie. Diese Schwellen sind bei einem 3-Jahres-Frakturisiko (für Schenkelhals und Wirbelkörperfrakturen) von 3 bis < 5 %, von 5 bis 10 % und von ≥ 10 % angesiedelt. Bei einem sehr hohen Frakturrisiko (Risiko ≥ 10 %) soll mit einer osteoanabol wirksamen Substanz behandelt werden, zwischen 5 und < 10 % soll eine Behandlung eingeleitet werden und es kann mit einem osteoanabolen Medikament therapiert werden. Im Bereich zwischen 3 und < 5 % sollte eine Therapie in Betracht gezogen werden. Diese Übersichtsarbeit kann nur einen Überblick über die aktualisierte Leitlinie geben. Für einen tieferen Einblick und für die Umsetzung in der Praxis sind die Kurz- bzw. Langversion nach der Veröffentlichung zusätzlich zu berücksichtigen.

Background Diverticular peroral endoscopic myotomy (POEM) is an alternative to surgery for the management of symptomatic thoracic esophageal diverticula. Conventionally, this requires proximal tunnel formation but a direct approach may simplify the technique. Herein, we report the outcomes of direct diverticular-POEM (DD-POEM).
Methods We conducted a single-center prospective observational study evaluating DD-POEM. This involved a direct approach to the diverticulum. Success was defined as an Eckardt score of ≤ 3 without the need for reintervention.
Results 10 patients underwent DD-POEM (median age 72 years; interquartile range [IQR] 14.3; male 60 % [n = 6]). Median diverticulum size was 40 mm (IQR 7.5) and median location was 35 cm from the incisors (IQR 8.3). Five patients (50 %) had an underlying dysmotility disorder. The median procedure duration was 60 minutes (IQR 28.8). There were no adverse events. The median hospital stay was 1 day (IQR 0.75). The pre-procedure median Eckardt score of 6 (IQR 4) significantly improved to 0 (IQR 0.75; P < 0.001) at a median follow-up of 14.5 months (IQR 13.8). Success was achieved in all patients.
Conclusions DD-POEM was a safe technique for the management of thoracic esophageal diverticula. Owing to its simplicity and excellent performance it should be further evaluated for the treatment of this disorder.

Abstract
Background Congenital aniridia is a severe malformation of almost all eye segments. Aniridia-associated keratopathy (AAK) and secondary glaucoma, which occur in more than 50% of
affected individuals, are typically progressive and pose a high risk of blindness for patients with congenital aniridia. Our aim was to investigate the effect of glaucoma treatment on AAK in
patients of the Homburg Aniridia Center.
Methods Our retrospective monocentric study included patients who underwent a comprehensive ophthalmological examination at the Homburg Aniridia Center between June 2003 and January
2022.
Results There were 556 eyes of 286 subjects (20.1 ± 20.1 years; 45.5% males) included. In 307 (55.2%) eyes of 163 subjects (27.5 ± 16.3 years; 43.1% males), glaucoma was present at
the time of examination. The mean intraocular pressure in the glaucoma group was 19.0 mmHg (± 8.0), while in the non-glaucoma group, it was 14.1 mmHg (± 3.6) (p < 0.001). In the glaucoma
group, 68 patients used antiglaucomatous topical monotherapy, 51 patients used 2 agents, 41 patients used 3 agents, 7 patients used quadruple therapy, and 140 did not use topical therapy
(e.g., after pressure-lowering surgery, pain-free end-stage glaucoma, or incompliance). Patients were classified according to the following stages of AAK: Stage 0 (96 eyes [17.2%], no
keratopathy), Stage 1 (178 eyes [32.0%]), Stage 2 (107 eyes [19.2%]), Stage 3 (67 eyes [12.0%]), Stage 4 (62 eyes [11.1%]), Stage 5 (45 eyes [8.0%]). The mean stage of AAK was 1.4
(1.2 – 1.5) in the group without eye drops, 1.9 (1.5 – 2.2) in the group with monotherapy, 1.8 (1.5 – 2.1) in the group with 2 drugs, 1.9 (1.5 – 2.2) in the group with 3 drugs, 3.4
(2.3 – 4.6) in the group with 4 drugs, and 3.3 (3.1 – 3.6) after antiglaucomatous surgery. The stage of AAK was significantly positively correlated with the number of pressure-lowering eye
drops (p < 0.05) and prior pressure-lowering surgery (p < 0.05). Prostaglandin analogues were not correlated with a higher AAK stage compared to the other drug groups.
Conclusions At the Homburg Aniridia Center, patients using topical antiglaucomatous quadruple therapy or who had previously undergone antiglaucomatous surgery had by far the highest
AAK stage. The different drug groups had no influence on the AAK stage.
Thermocoagulation in Multiple Targets to Treat Obsessive-Compulsive Disorder Associated with Drug Addiction: Case Report
Authors: Assis Laryssa Simões de Lima , Carvalho Laura Araújo de , Silva Ledismar José da 
Published: October 2023

AbstractSubstance-related disorders are chronic psychiatric conditions defined by substance abuse, and they compromise patients both clinically and functionally. Currently, pharmacotherapy, behavioral therapy, or an association of both are the treatments of choice for obsessive-compulsive disorder associated with drug addiction. However, the refractoriness to treatment, as a result of the high failure rates of these approaches, has led to the need to develop surgical techniques to treat severe cases of substance-related disorders. In the present article, we report the case of a patient who underwent neurosurgery through the stereotactic technique after refractoriness to the conventional treatment for drug addiction. The patient showed sustained improvement in his addiction to drugs. Despite the numerous reports on the effectiveness and applicability of neurosurgery in psychiatric disorders, some concerns regarding stereotactic surgery as a treatment for drug addiction still remain, especially in relation to its efficacy, safety, and ethical implications.
