Mimik und Emotion
Authors: Klingner Carsten M. , Guntinas-Lichius Orlando 
Published: May 2023

ZusammenfassungDie menschliche Mimik ist einzigartig in ihrer Fähigkeit unseren
Emotionen Ausdruck zu verleihen und diese anderen Menschen zu
übermitteln. Die mimische Expression grundlegender Emotionen ist
über verschiedene Kulturen hinweg sehr ähnlich und du weist auch
Gemeinsamkeiten zu anderen Säugetieren auf. Dies deutet auf einen
gemeinsamen genetischen Ursprung des Zusammenhangs von Mimik und Emotion. Neuere
Untersuchungen zeigen aber auch kulturelle Einflüsse und Unterschiede.
Die Erkennung von Emotionen aus der Mimik und auch der Prozess des mimischen
Ausdrucks der eigenen Emotionen erfolgt in einem äußerst
komplexen zerebralen Netzwerk. Aufgrund der Komplexität des zerebralen
Verarbeitungssystems gibt es eine Vielzahl von neurologischen und
psychiatrischen Erkrankungen, welche die Kopplung von Mimik und Emotionen
erheblich stören können. Auch durch das Tragen von Masken wird
unsere Fähigkeit zur Übermittlung und zum Erkennen von Emotionen
über die Mimik eingeschränkt. Durch die Mimik lassen sich aber
nicht nur „echte“ Emotionen ausdrücken, sondern auch
gespielte. Damit eröffnet die Mimik die Möglichkeit sozial
erwünschten Ausdruck vorzuspielen und auch Emotionen bewusst
vorzutäuschen. Diese Täuschungen sind jedoch zumeist nicht
perfekt und können von kurzfristigen Gesichtsbewegungen begleitet sein,
die auf die tatsächlich vorhandenen Emotionen hinweisen
(Mikroexpressionen). Diese Mikroexpressionen sind von nur sehr kurzer Dauer und
vom Menschen häufig kaum wahrnehmbar, jedoch das ideale Anwendungsgebiet
für computergestützte Analysen. Diese automatische
Identifikation von Mikroexpressionen hat in den letzten Jahren nicht nur
wissenschaftliche Aufmerksamkeit erfahren, sondern ihr Einsatz wird auch in
sicherheitsrelevanten Bereichen getestet. Der vorliegende Artikel fasst den
aktuellen Wissensstand von Mimik und Emotionen zusammen.

Zusammenfassung
Ziel der Studie Die FACT-PGx Studie sollte Barrieren bei der
Implementierung von pharmakogenetischen Testungen auf Station einer
psychiatrischen Klinik aufdecken, um sie in Folge überwinden zu
können, so dass die flächendeckende Implementierung schneller
erfolgen kann.
Methodik 104 Patienten (50% Frauen) mit F32.x oder F33.x wurden
genotypisiert. 67 Patienten (64%; 57% Frauen) beantworteten den
selbstentwickelten Fragebogen. Der Einfluss demografischer Daten wie
Bildungsstand, Alter und Vorbehandlungen die Antworten des Fragebogens wurden
mittels t-Test (kategorial) Wilcoxon-Rank-Test (kontinuierlich) untersucht.
Ergebnisse Kein Patient lehnte eine Genotypisierung ab. 99%
glaubten, dass PGx ihren Aufenthalt verkürzen könne. Patienten
>40 Jahre und mit höherem Bildungsgrad waren eher bereit, Geld
für eine Genotypisierung auszugeben (beides p=0.009).
Durchschnittlich waren die Patienten bereit, im Mittel 117,42 €
+/- 140,49 € auszugeben und 15,83+/-
8,92 Tage auf Befunde zu warten. Die Prozessabläufe für eine
Genotypisierung in der Klinik unterscheiden sich von dem Routinelabor.
Schlussfolgerung Patienten stellen bei der Implementierung keine Barriere
dar, sondern befördern eher die Implementierung. Prozessabläufe
können Barrieren darstellen, die jedoch durch Optimierung
überwunden werden können.

Abstract
Purpose To assess various potential factors on human limbal epithelial cell (LEC) outgrowth in vitro using corneal donor tissue following long-term storage (organ culture) and a stepwise linear regression algorithm.
Methods Of 215 donors, 304 corneoscleral rings were used for our experiments. For digestion of the limbal tissue and isolation of the limbal epithelial cells, the tissue pieces were incubated with 4.0 mg/mL collagenase A at 37 °C with 95% relative humidity and a 5% CO2 atmosphere overnight. Thereafter, limbal epithelial cells were separated from limbal keratocytes using a 20-µm CellTricks filter. The separated human LECs were cultured in keratinocyte serum-free medium medium, 1% penicillin/streptomycin (P/S), 0.02% epidermal growth factor (EGF), and 0.3% bovine pituitary extract (BPE). The potential effect of donor age (covariate), postmortem time (covariate), medium time (covariate), size of the used corneoscleral ring (360°, 270°180°, 120°, 90°, less than 90°) (covariate), endothelial cell density (ECD) (covariate), gender (factor), number of culture medium changes during organ culture (factor), and origin of the donor (donating institution and storing
institution, factor) on the limbal epithelial cell outgrowth was analyzed with a stepwise linear regression algorithm.
Results The rate of successful human LEC outgrowth was 37.5%. From the stepwise linear regression algorithm, we found out that the relevant influencing parameters on the LEC growth were intercept (p < 0.001), donor age (p = 0.002), number of culture medium changes during organ culture (p < 0.001), total medium time (p = 0.181), and size of the used corneoscleral ring (p = 0.007), as well as medium time × size of the corneoscleral ring (p = 0.007).
Conclusions The success of LEC outgrowth increases with lower donor age, lower number of organ culture medium changes during storage, shorter medium time in organ culture, and smaller corneoscleral ring size. Our stepwise linear regression algorithm may help us in optimizing LEC cultures in vitro.
Digital Smile Makeover: A Multidisciplinary Team Approach
Authors: Nourah Dalia 
Published: May 2023

AbstractAesthetics is a fundamental part of contemporary dental practice. A pleasant smile depends on the gingival tissue architecture and dental characteristics. Excessive gingival display (gummy smile) is considered an unattractive smile and can affect a person's confidence. There are many etiological factors related to a gummy smile. Aesthetic rehabilitation of these cases often requires an interdisciplinary approach and close collaboration between dental specialties. This article describes an approach to excessive gingival display management caused by short teeth and hyperactive lips using a digital workflow for crown lengthening. A digital approach enables predictable planning and decreases the need for postsurgical modifications, thus shortening the treatment duration. Computer software is used for planning and 3D-printed guide for crown lengthening and implant placement. Two months later, lip repositioning was performed to reduce the hyperactive lip. After 4 months, prosthetic treatment and Botox injections were done to restore an aesthetic smile.
Ligand and solvent effects on the absorption spectra of CdS magic-sized clusters

Published: May 2023

The absorption spectra of congenetic wurtzite (WZ) and zincblende (ZB) CdS magic-sized clusters are investigated. We demonstrate that the exciton peak positions can be tuned by up to 500 meV by varying the strong coupling between X-type ligands and the semiconductor cores, while the addition of L-type ligands primarily affects cluster midgap states. When Z-type ligands are displaced by L-type ligands, red shifts in the absorption spectra are observed, despite the fact there is a small decrease in cluster size. Density functional theory calculations are used to explain these findings and they reveal the importance of Cd and S dangling bonds on the midgap states during the Z- to L-type ligand exchange process. Overall, ZB CdS clusters show higher chemical stability than WZ clusters but their optical properties exhibit greater sensitivity to the solvent. Conversely, WZ CdS clusters are not stable in a Lewis base-rich environment, resulting in various changes in their spectra. Our findings enable researchers to select capping ligands that modulate the optical properties of semiconductor clusters while maintaining precise control over their solvent interactions.
Investigation of oxygen-vacancy complexes in diamond by means of ab initio calculations

Published: May 2023

Abstract
Point defects in diamond may act as quantum bits. Recently, oxygen-vacancy related defects have been proposed to the origin of the so-called ST1 color center in diamond that can realize a long-living solid-state quantum memory. Motivated by this proposal we systematically investigate oxygen-vacancy complexes in diamond by means of first principles density functional theory calculations. We find that all the considered oxygen-vacancy defects have a high-spin ground state in their neutral charge state, which disregards them as an origin for the ST1 color center. We identify a high-spin metastable oxygen-vacancy complex and characterize their magneto-optical properties for identification in future experiments.

Authors: Gangwar Manvendra Singh , Agarwal Pratima 
Published: May 2023

Abstract
The growth of the metallic nanoparticles (NPs) on the solid substrate with the desired shape and size is a critical issue for application of these NPs in solid-state devices. Solid state dewetting (SSD) technique is simple, low cost and can be used to fabricate the metallic NPs with control on the shape and size on different substrates. In this work, silver NPs (Ag NPs) were grown on corning glass substrate by SSD of silver precursor thin film deposited at different substrate temperatures by RF sputtering. The influence of the substrate temperature on the growth of Ag NPs and their several properties like localized surface plasmon resonance (LSPR), photoluminescence (PL), and Raman spectroscopy is studied. The size of the NPs was found to vary from 25 nm to 70 nm with the variation in substrate temperature from room temperature (RT) to

. For the RT films, the LSPR peak position of Ag NPs is around 474 nm. A red shift in LSPR peak for films deposited at higher temperature is observed due to change in the particle size and interparticle separation. Photoluminescence spectra suggests the presence of two photoluminescence bands at 436 and 474 nm corresponding to Ag NPs radiative interband transition and LSPR band. An intense Raman peak was observed at 1587 cm−1. Enhancement in PL peak intensity and Raman peak intensity is found to be in accordance with the LSPR of Ag NPs.

Published: May 2023

Abstract
Recent progress in the in situ synthesise of various nanomaterials has gained tremendous interest and wide applications in various fields. For the first time to the best of our knowledge, this work reports a methodology of ultra-fast in situ synthesis of cobalt–cobalt oxide-reduced graphene oxide (Co−Co3O4−rGO (CC–rGO)) composite by laser ablation. The photothermal reduction technique was leveraged to develop the CC–rGO. For this, a low-cost 450 nm blue diode laser was irradiated onto a grade 1 filter paper in the presence of cobalt ions readily patterns the carbon matrix of paper to the composite material. Moreover, the variation of cobalt concentrations from 0.1–0.5 M led to structural and morphological changes. Standard techniques were adopted for thorough characterizations of developed sensor material for conductivity analysis, specific surface area, crystal-structural information, surface morphology, and chemical composition. The observed results were highly promoting towards the electrochemical sensing applications. Further, the developed sensor was found to be highly selective toward detecting a vital bio analyte alkaline phosphatase (ALP). The sensors performance was highly significant in the linear range of 10–800 mU l−1 with a detection limit of 10.13 mU l−1. The sensors applicability was further validated in actual human serum samples via a recovery-based approach. In the future, the developed in situ material methodology can begin a rapid composite material synthesis at a larger scale.

The synthesized NCs were characterized in detail by using appropriate techniques such as x-ray diffraction, transmission electron microscopy, and optical spectroscopies. The luminescence evolution of the synthesized NCs is as follows: from the broad spectrum (peaking at 756 nm) of the AgInS2 core NCs to become the narrow excitonic emission (at 575 nm) prominent beside the broad one after shelling with GaS

Authors: Hou Tianjie , Wang Shufen , Li Jianmin , Wang Yu , Zhang Yang , Cao Lei , Xiong Shixian , Fan Lanlan , Gu Feng 
Published: May 2023

Abstract
Intelligent actuators offer a lot of potential for use in soft robots, artificial muscles, sensors since it can alter shape in response to external stimuli. However, the stiffness of the material and the constrained specific surface area brought on by the dense stacking of materials restrict the response of the conventional humidity-responsive actuators. Herein, optimal humidity-responsive actuators of MXene were developed by designing topologies of heterostructured membrane of stacked nanosheets and 3D wrinkled MXene (3D-MXene). In this configuration, the stacked MXene nanosheets sustain the device’s overall strength, while the 3D-MXene layer significantly improves the device’s moisture absorption and decreases its stiffness. Importantly, the actuators have been strengthened due to the van der Waals forces at the interface of the stacked nanosheets and 3D-MXene. The fabricated MXene/3D-MXene actuator has exhibited remarkable response speed and deformation ability, obviously superior to any previously reported humidity-responsive actuators. By combining excellent electrical conductivity, the developed actuators demonstrated rapid response for electrical switches. This work highlights the significant potential for developing high performance responsive actuators by designing heterostructured configurations for applications in intelligent switches, soft robotics and synthetic muscles.
On multi-hump solutions of reverse space-time nonlocal nonlinear Schrödinger equation
Authors: Hanif Y , Saleem U 
Published: May 2023

Abstract
In this article multi-soliton solutions of reverse space-time nonlocal nonlinear Schr ödinger (NLS) equation have been constructed. Darboux transformation is applied to the associated linear eigenvalue problem for the generalized NLS equation and we obtain a determinant formula for multi-soliton solutions. Under suitable reduction conditions and appropriate choice of spectral parameters, the generalized expression of first-order nontrivial solution gives some novel solutions such as double-hump and flat-top soliton solutions for reverse space-time nonlocal NLS equation. The dynamics and interaction of double-hump soliton solutions are studied in detail and it is indicated that these solutions undergo collisions without any energy redistribution. For higher-order double-hump solutions, the relative velocities of solitons play a crucial role to have humps and also induce nonlinear interference in the collision zone. The dynamics of individual decaying and growing unstable and stable double-humps as well as their interactions are explained and illustrated.
Langevin simulation of dark matter kinetic equilibration
Authors: Kim Seyong , Laine M. 
Published: May 2023

AbstractRecently it has been questioned, notably in the context of the scalar singlet dark matter model withmφ≃ 60 GeV, how efficiently kinetic equilibrium is maintained if freeze-out dynamics is pushed down to low temperatures by resonant effects. We outline how Langevin simulations can be employed for addressing the non-equilibrium momentum distribution of non-relativistic particles in a cosmological background. For a scalar singlet massmφ≃ 60 GeV, these simulations suggest that kinetic equilibrium is a good approximation down toT∼ 1 GeV, with the deviation first manifesting itself as a red-tilted spectrum. This reduces the annihilation cross section, confirming findings from other methods that a somewhat larger (< 20%) coupling than in equilibrium is needed for obtaining the correct abundance.
A Compact Full-disk Solar Magnetograph Based on Miniaturization of the GONG Instrument*
Authors: Gosain Sanjay , Harvey John , Martinez Pillet Valentin , Hill Frank , Woods Thomas N. 
Published: May 2023

Abstract
The design of compact instruments is crucial for the scientific exploration by smaller spacecraft such as CubeSats and deep space missions, as these missions require minimal instrument mass. In this proof-of-concept study, we demonstrate the miniaturization of the Global Oscillation Network Group (GONG) instrument. GONG instruments routinely produce full-disk maps of the Sun’s photosphere using the Ni i 676 nm absorption line, measuring Doppler shifts and magnetic fields. To miniaturize the GONG optical design, we propose replacing the bulky Lyot filter with a narrow-band interference filter. We validate this concept through numerical modeling and proof-of-concept observations. Finally, we propose a simple optical design for building a compact version of GONG.

Abstract
We report the first application of compression optical coherence elastography (C-OCE) to evaluate both linear and nonlinear elastic properties of lymph nodes (LNs) for assessing their status, which is an important factor for detecting metastasis and staging breast cancer. The reported study involved 27 excised sentinel and axillary LNs from 24 patients with breast cancer, including normal LNs (n = 6), reactive LNs with follicular hyperplasia (n = 7) and sinus histiocytosis (n = 8), and metastatic LNs (n = 6). C-OCE data were compared with co-registered gold-standard histopathology and demonstrated a significantly higher contrast in differentiation of LNs as compared to structural optical coherence tomography imaging. Normal LNs are characterized by low stiffness values in the areas of LN cortex (<200 kPa). C-OCE revealed that abnormal reactive LNs with follicular hyperplasia exhibit moderately increased stiffness (200–300 kPa) in the cortex areas and more pronounced stiffness increase (400–600 kPa) in the areas of sinus histiocytosis. LNs with total metastasis exhibit fairly uniformly distributed highest stiffness values (>600 kPa). Since in terms of the tangent Young’s modulus there remained an appreciable overlap among these types of LNs, we also evaluated their elastic nonlinearity parameters. Complementary usage of both linear and nonlinear elastic parameters enabled very clear differentiation of all four main states of LNs. Thus, C-OCE imaging demonstrates high potential for future intraoperative usage to rapidly determine the LN status during breast-conserving surgery and to assess the extent of the cancer cells propagation in regional lymphatic collectors for preserving benign LNs. This is important for reducing the associated risks and complications (such as lymphedema) from excessive surgical removal of lymphoid structures.

Abstract
The INO collaboration is designing a cosmic muon veto detector (CMVD) to cover the mini-ICAL detector which is operational at the IICHEP transit campus, Madurai in South India. The aim of the CMVD is to study the feasibility of building an experiment to record rare events at a shallow depth of around 100 m, and use plastic scintillators to veto atmospheric muons from those produced by the rare interactions within the target mass of the detector. The efficiency of such a veto detector should be better than 99.99% and false positive rate should be less than 10-5.

The CMVD is being built using extruded plastic scintillator (EPS) strips to detect and tag atmospheric muons. More than 700 EPS strips are required to build the CMVD. Two EPS strips are pasted together to make a di-counter (DC) and wavelength shifting fibres are embedded inside the EPS strips to trap the scintillation light generated by a passing cosmic ray muon and transmit it as secondary photons to the Silicon Photo-Multipliers (SiPMs) mounted at the two ends of the DCs. Since the efficiency requirement of the veto detector is rather high, it is imperative to thoroughly test each and every component used for building the CMVD. A cosmic ray muon telescope has been setup using the DCs to qualify all the DCs that will be fabricated. In this paper we will discuss the details of the design and fabrication of the DCs, the cosmic muon setup and the electronics used for their testing and the test results.
