Authors: Grünherz Lisanne , von Reibnitz Donata , Lindenblatt Nicole 
Published: April 2024

ZusammenfassungIn den letzten Jahren finden speziell für die Mikrochirurgie entwickelte Roboter
insbesondere in der rekonstruktiven Lymphchirurgie zunehmend Anwendung. Derzeit
gibt es zwei Robotersysteme, welche in der Mikrochirurgie eingesetzt werden.
Beide Systeme verfügen über Technologien zur Tremorreduzierung und
Bewegungsskalierung, wodurch die Präzision und Geschicklichkeit des Chirurgen
optimiert werden sollen. In der Klinik für Plastische Chirurgie und
Handchirurgie des Universitätsspitals Zürich wird das Symani Surgical System bei
vielen mikro- und supermikrochirurgischen Operationen eingesetzt. Das
Hauptanwendungsgebiet des Robotersystems liegt in der rekonstruktiven
Lymphchirurgie, im Speziellen robotisch-assistierte lymphovenöse Anastomosen,
der mikrochirurgische Anschluss des Lymphgewebslappens sowie der Anwendung in
der zentralen Lymphchirurgie. Hierbei ermöglicht die Verwendung des Roboters
kleinere Operationszugänge für anatomisch tiefe Strukturen und eine Verbesserung
der chirurgischen Präzision. In Kombination mit einem Exoskop kann es zudem die
Ergonomie des Mikrochirurgen verbessern.
Association Between Triglyceride-Glucose Index and Diabetic
Retinopathy: A Meta-Analysis
Authors: Yu Lanchu , Li Bingqing 
Published: April 2024

AbstractThe objective of this study was to assess the relationship between the
triglyceride-glucose (TyG) index, a recently proposed marker of insulin
resistance, and the occurrence of diabetic retinopathy (DR), a complication
associated with cardiovascular risk. This systematic review and meta-analysis
aimed to evaluate the association between the TyG index and DR. To achieve the
objective of the meta-analysis, an extensive search was conducted on databases
such as PubMed, Embase, and Web of Science to identify observational studies
with longitudinal follow-up. Random-effects models were employed to combine the
findings, taking into account the potential influence of heterogeneity. Twelve
observational studies from 11 reports were included in the meta-analysis, which
involved 16 259 patients with type 2 diabetes (T2D). Among them, 4302 (26.5%)
were diagnosed as DR. Pooled results showed that a higher TyG index was
associated with a higher risk of DR [odds ratio (OR) for the fourth versus the
first quartile of TyG index: 1.91, 95% confidence interval (CI): 1.44 to 2.53,
p<0.001; I2=72%]. Meta-analysis of TyG index analyzed in continuous variable
showed consistent results (OR for per 1 unit increment of TyG index: 1.41, 95%
CI: 1.08 to 1.86, p=0.01; I2=82%). Subgroup analysis showed that adjustment of
HbA1c or the duration of diabetes did not significantly affect the results (p
for subgroup difference all>0.05). In conclusion, a high TyG index was
associated with the risk of DR in T2D patients.

Data
Authors: Mori Francesco , Menichini Giulio , Rizzo Francesco , Sassu Paolo , Innocenti Marco 
Published: April 2024

Abstract
Background The evolution of microsurgery has relied on advancements in
operating microscopes and surgical instruments. Pioneering advancements,
however, especially within the domain of “super-microsurgery”, challenge the
limits of human dexterity by dealing with anastomoses between vessels smaller
than 0.8 mm. Based on these premises, the Symani robotic system was designed and
developed. This platform utilizes teleoperation and motion-scaled movement to
provide surgeons with precision and accuracy in manipulating millimetre and
submillimetre-sized anatomical structures. In this study, we present our
experience in performing robotic-assisted anastomoses using the Symani Surgical
System in free flap reconstruction.
Methods We present a comprehensive analysis of all reconstructive
procedures involving microsurgical free flaps performed using the Symani robotic
platform at the orthoplastic unit of the Rizzoli Orthopaedic Institute from 1
October 2022 to 1 May 2023.
Results Sixteen microsurgical reconstructions using free flaps were
performed, involving a total of 40 anastomoses on vessel calibres ranging from
0.6 mm to 2.5 mm. In each case, the anastomosis was executed with the assistance
of the robotic platform, achieving a 100+% success rate in patent anastomoses,
and no major complications occurred.Conclusion The Symani system has proven to be safe and reliable in performing
microsurgical anastomoses. While this platform demonstrated successful in
various vessel calibres, its most promising potential lies in anastomoses below
the size of a millimetre. Larger patient cohorts and extended investigation
periods will be essential to explore whether robotics in microsurgery offers
advantages across all microsurgical procedures or should be reserved for
selected cases.
Sozialpsychiatrische Konzepte in der BRD und der DDR – Ein Vergleich
der theoretischen Ansätze von Karl Peter Kisker sowie Klaus Weise und Achim
Thom
Authors: Buttler Johann , Steinberg Holger 
Published: April 2024

ZusammenfassungDie Studie zeigt in den Grundvorstellungen des Psychiaters Karl Peter Kisker
sowie des Psychiaters Klaus Weise und Philosophen Achim Thom das gemeinsame
Anliegen ab den 1960ern, psychisch Kranken zu mehr Selbstbestimmung und
gesellschaftlicher Teilhabe zu verhelfen und die Psychiatrieversorgung zu
humanisieren. Aus der Gesamtschau wird zunächst die theoretische Konzeption von
Kisker dargestellt, der ein Vertreter der westdeutschen
Sozialpsychiatriebewegung war und eine phänomenologisch-anthropologische Prägung
aufwies. In Gegenüberstellung wird der ostdeutsche Ansatz von Weise und Thom
erläutert, der an die phänomenologisch-anthropologische Subjektorientiertheit
anknüpfte, aber mit der Einbeziehung einer marxistischen Auffassung eine
sozialistische Sozialpsychiatrie begründete. Im Vergleich werden trotz vieler
Übereinstimmungen die unterschiedlichen Gewichtungen der beiden Ansätze
deutlich, die soziale Dimension des psychischen Krankseins zu verstehen.

On the way to deep fake democracy? Deep fakes in election campaigns in 2023
Authors: Łabuz Mateusz , Nehring Christopher 
Published: April 2024

AbstractThe development of generative artificial intelligence raises justified concerns about the possibility of undermining trust in democratic processes, especially elections. Deep fakes are often considered one of the particularly dangerous forms of media manipulation. Subsequent research confirms that they contribute to strengthening the sense of uncertainty among citizens and negatively affect the information environment. The aim of this study is to analyse the use of deep fakes in 11 countries in 2023, in the context of elections and to indicate potential consequences for future electoral processes, in particular with regard to the significant number of elections in 2024. We argue that a so-called “information apocalypse” emerges mainly from exaggeratedly alarmist voices that make it difficult to shape responsible narratives and may have the features of a self-fulfilling prophecy. Thus, we suggest to use the term “pollution” instead and improve scientific and journalistic discourse that might be a precondition for reducing threats that touch on social reactions to deep fakes and their potential.
Long-range distributed vibration sensing based on internal-modulation OFDR
Authors: Yue Yaoli , Zeng Jing , Ding Zhenyang , Zhang Teng , Guo Haohan , Liu Tiegen 
Published: April 2024

Presented here is long-range distributed vibration sensing based on internal-modulation optical frequency domain reflectometry (OFDR). In the proposed system with internal modulation, a silicon-based photonic-chip laser is used as the laser source, and by controlling the output voltage curve of an arbitrary waveform generator to induce temperature change in the external cavity of the laser, a 10-GHz optical frequency tuning range is achieved. The complexity of the proposed internal-modulation system is lower than that of the traditional external-modulation OFDR system that combines a narrow-linewidth laser with a single-sideband modulator to achieve wavelength tuning. Cross-correlation analysis is used as a sensing mechanism to evaluate the similarity between Rayleigh scatter signals and to achieve vibration event localization. Experimental comparison is made of the vibration sensing performance of the external- and internal-modulation systems, and for a vibration event generated at a distance of 100.95 km, they locate it with a sensing spatial resolution of 43.0 m and 16.8 m, respectively. The results indicates that the proposed distributed vibration sensing based on internal modulation has better sensing performance and lower complexity compared to the traditional external-modulation system. In addition, the proposed system is single-ended and involves no optical amplification, which makes it very suitable for ultra-long-range sensing.
Exploiting graded triangular gratings for optimal nano-focusing: A novel approach to enhance SERS efficiency
Authors: Zeineddine Ali , Shayegannia Moein , Kherani Nazir P. , Loh Joel Y. Y. 
Published: April 2024

Plasmonic graded nano-gratings enable rainbow trapping of multiple resonant modes over a wide wavelength spectrum, useful for multi-channel Surface Enhanced Raman Spectroscopy (SERS) of molecular species. However, rectangular nano-gratings have limitations in achieving efficient rainbow trapping and localizing a wide spectrum of plasmonic modes due to their stepwise geometry, which induces high dissipation of surface plasmon polaritons into the substrate. An alternative platform of graded triangular nano-gratings enables increased localization and more efficient adiabatic transformation between neighboring grooves. Varying groove angles, depths, and periods in the tapered geometry allow for smooth adjustment of the surface plasmon polariton propagation constant, reducing losses and maximizing nano-focusing inside the groove tips. To overcome the limitation of low aspect ratio in wet-etching silicon, we employed a multi-step process of reactive ion etching of a SiO2 barrier layer to generate aperture width, followed by anisotropic wet-etching. The resulting graded triangular nano-gratings showed excellent SERS enhancement along three laser wavelength excitations. The enhancement factors of 638 and 785 nm wavelengths are 8.5 × 109 and 9 × 108, respectively, for the detection of 1 µM Rhodamine 6G. In addition, graded triangular nano-gratings show similar enhancement factors for other species, specifically the lipid DPEE-PEG, at the 532 nm laser excitation wavelength with an excellent SERS enhancement factor of 1.5 × 109. Owing to the ability of the graded triangular gratings to elicit pronounced SERS responses across three distinct laser excitations, they unequivocally qualify as “rainbow trapping” structures. Wider apertures, lower ohmic losses, and the ability to tune the groove angle beyond conventional etching methods bode well for graded triangular gratings as a superior platform for miniature sensors.
Probing the electronic structure and ground state symmetry of gas phase C60+ via VUV photoionization and comparison with theory

Published: April 2024

Recently, some of us reviewed and studied the photoionization dynamics of C60 that are of great interest to the astrochemical community as four of the diffuse interstellar bands (DIBs) have been assigned to electronic transitions in the C60+ cation. Our previous analysis of the threshold photoelectron spectrum (TPES) of C60 [Hrodmarsson et al., Phys. Chem. Chem. Phys. 22, 13880–13892 (2020)] appeared to give indication of D3d ground state symmetry, in contrast to theoretical predictions of D5d symmetry. Here, we revisit our original measurements taking account of a previous theoretical spectrum presented in the work of Manini et al., Phys. Rev. Lett. 91(19), 196402 (2003), obtained within a vibronic model parametrized on density functional theory/local-density approximation electronic structure involving all hg Jahn–Teller active modes, which couple to the 2Hu components of the ground state of the C60+ cation. By reanalyzing our measured TPES of the ground state of the C60 Buckminsterfullerene, we find a striking resemblance to the theoretical spectrum calculated in the work of Manini et al., Phys. Rev. Lett. 91(19), 196402 (2003), and we provide assignments for many of the hg modes. In order to obtain deeper insights into the temperature effects and possible anharmonicity effects, we provide complementary modeling of the photoelectron spectrum via classical molecular dynamics (MD) involving density functional based tight binding (DFTB) computations of the electronic structure for both C60 and C60+. The validity of the DFTB modeling is first checked vs the IR spectra of both species which are well established from IR spectroscopic studies. To aid the interpretation of our measured TPES and the comparisons to the ab initio spectrum we showcase the complementarity of utilizing MD calculations to predict the PES evolution at high temperatures expected in our experiment. The comparison with the theoretical spectrum presented in the work of Manini et al., Phys. Rev. Lett. 91(19), 196402 (2003), furthermore, provides further evidence for a D5d symmetric ground state of the C60+ cation in the gas phase, in complement to IR spectroscopy in frozen noble gas matrices. This not only allows us to assign the first adiabatic ionization transition and thus determine the ionization energy of C60 with greater accuracy than has been achieved at 7.598 ± 0.005 eV, but we also assign the two lowest excited states (2E1u and 2E2u) which are visible in our TPES. Finally, we discuss the energetics of additional DIBs that could be assigned to C60+ in the future.
Prediction of the univariant two-phase coexistence line of the tetrahydrofuran hydrate from computer simulation
Authors: Algaba Jesús , Romero-Guzmán Cristóbal , Torrejón Miguel J. , Blas Felipe J. 
Published: April 2024

In this work, the univariant two-phase coexistence line of the tetrahydrofuran (THF) hydrate is determined from 100 to 1000 bar by molecular dynamics simulations. This study is carried out by putting in contact a THF hydrate phase with a stoichiometric aqueous solution phase. Following the direct coexistence technique, the pressure is fixed, and the coexistence line is determined by analyzing if the hydrate phase grows or melts at different values of temperature. Water is described using the well-known TIP4P/Ice model. We have used two different models of THF based on the transferable parameters for phase equilibria-united atom approach (TraPPE-UA), the original (flexible) TraPPe-UA model and a rigid and planar version of it. Overall, at high pressures, small differences are observed in the results obtained by both models. However, large differences are observed in the computational efforts required by the simulations performed using both models, being the rigid and planar version much faster than the original one. The effect of the unlike dispersive interactions between the water and THF molecules is also analyzed at 250 bar using the rigid and planar THF model. In particular, we modify the Berthelot combining rule via a parameter ξO-THF that controls the unlike water–THF dispersive interactions. We analyze the effect on the dissociation temperature of the hydrate when ξO-THF is modified from 1.0 (original Berthelot combining rule) to 1.4 (modified Berthelot combining rule). We use the optimized value ξO-THF = 1.4 and the rigid THF model in a transferable way to predict the dissociation temperatures at other pressures. We find excellent agreement between computer simulation predictions and experimental data taken from the literature.
Rigid covalent bond of α-sulfur investigated via temperature-dependent EXAFS

Published: April 2024

Abstract
This study performs extended x-ray absorption fine structure (EXAFS) measurements for the S-K edge in the temperature range of 10 and 300 K in the transmission mode using a photodiode to detect the transmitted x-rays. It provides the first report of temperature variations in the structural parameters of α-S. As the temperature increases from 10 to 300 K in the Fourier transform of

(

)

the first peak corresponding to the covalent bond of the eight-membered ring becomes slightly low anomalously despite thermal disturbances. However, as in normal materials, the second peak at 300 K decreases to approximately half of that at 10 K, which contains several intra- and inter-ring correlations. All structural parameters of the covalent bond obtained by nonlinear least squares fitting exhibit missing temperature variations. A value of zero for the asymmetric parameter in the EXAFS (C
3) implies that the potential of the covalent bond is symmetric, and the constant value of the mean square relative displacement (MSRD) with temperature implies that the potential is extremely high. The Einstein model fitting for the temperature variation in the MSRD yields an Einstein temperature of 942 K and force constant (K) of 405 N m−1. The value of K is the largest among those of chalcogen elements.
Magic-angle twisted bilayer graphene under orthogonal and in-plane magnetic fields
Authors: Bigeard Gaëlle , Cresti Alessandro 
Published: April 2024

Abstract
We investigate the effect of a magnetic field on the band structure of bilayer graphene with a magic twist angle of 1.08∘. The coupling of a tight-binding model and the Peierls phase allows the calculation of the energy bands of periodic two-dimensional systems. For an orthogonal magnetic field, the Landau levels are dispersive, particularly for magnetic lengths comparable to or larger than the twisted bilayer cell size. A high in-plane magnetic field modifies the low-energy bands and gap, which we demonstrate to be a direct consequence of the minimal coupling.
