Published: February 2024

ZusammenfassungFür Frakturen entlang der Wirbelsäule besteht ein Konsens über den Diagnosealgorithmus und die Behandlung. Das Kreuzbein stellt eine knöcherne Verbindung zwischen der Wirbelsäule und dem Becken her und überträgt und gleicht Kräfte von den unteren Extremitäten auf den Rumpf und umgekehrt aus. Diese anatomische Position macht es anfällig für Frakturen als Teil des Beckenrings und Frakturen aufgrund axialer Kräfte durch die Wirbelsäule. Für eine gute klinische Praxis ist es wichtig, den Traumamechanismus und das Alter des Patienten zu berücksichtigen. Für das geriatrische Patientenkollektiv haben sich die Klassifikationen Fragilitätsfraktur des Beckens (FFP) und Osteoporosefraktur des Beckens (OF) etabliert und stellen eine einfache Entscheidungshilfe im Praxisalltag dar. Jüngere Patienten erleiden häufiger Hochenergietraumata und Verletzungen, die sich nicht auf den knöchernen Anteil des Beckenringes beschränken. Bei diesen oft komplexeren Verletzungen kann die AO-Klassifikation bei der Therapientscheidungsfindung hilfreich sein. Die Notwendigkeit von Interventionen zur Stabilisierung des Patienten im Rahmen eines „damage control“-Ansatzes bestimmen die therapeutische Strategie bei der Behandlung dieser Patienten. Die folgenden Erläuterungen zur Klassifizierung und der daraus resultierenden Therapie können dabei helfen, Sakrumfrakturen als eigenständige Entität sowohl im Sinne der verlängerten Wirbelsäule als auch des Beckenrings zu differenzieren.

Efficient Synthesis of (2Z,5Z)-3-Benzyl/alkyl-5-(2-oxo-5-aryl-3 (2H)-furanylidene)-2-(phenylimino)-1,3-thiazolidin-4-ones via a One-Pot Three-Component Reaction
Authors: Alizadeh Abdolali , Moterassed Reihaneh 
Published: February 2024

AbstractA simple and efficient strategy for the chemoselective synthesis of (2Z,5Z)-3-benzyl/alkyl-5-(2-oxo-5-arylfuran-3(2H)-ylidene)-2-(phenylimino)thiazolidin-4-one derivatives is developed via a sequential three-component reaction of readily available phenacyl bromides, pyridine and methyl 2-(3-benzyl/alkyl-4-oxo-2-(phenylimino)thiazolidin-5-ylidene)acetates in acetonitrile at room temperature. The advantages of this one-pot sequential Michael addition/1,2-H shift/elimination of pyridine/intramolecular cyclization are highlighted by its low energy requirements (short reaction times at room temperature), excellent yields, the absence of a metal catalyst, and mild conditions. The product structures are characterized by spectroscopic techniques and single-crystal X-ray analysis.
Predictive Value of Corrected 18F-FDG PET/CT Baseline Parameters for Primary DLBCL Prognosis: A Single-center Study
Authors: Li Min , Liu Jianpeng , Liu Fangfei , Lv Rongbin , Bai Haowei , Liu Shuyong 
Published: February 2024

Abstract
Objective The purpose of this study was to evaluate the prognostic significance of corrected baseline metabolic parameters in fluorodeoxyglucose positron emission tomography imaging (18F-FDG PET/CT) for 3-year progression-free survival (PFS) in patients with primary diffuse large B cell lymphoma (DLBCL).
Patients and Methods Retrospective clinical and pathological data were collected for 199 patients of DLBCL diagnosed between January 2018 and January 2021. All patients underwent 18F-FDG PET/CT scans without any form of treatment. The corrected maximum standardized uptake value (corSUVmax), corrected mean standardized uptake value (corSUVmean), corrected whole-body tumor metabolic volume sum (corMTVsum), and corrected total lesion glycolysis of whole body (corTLGtotal) were corrected using the SUVmean in a 1-cm diameter mediastinal blood pool (MBP) from the descending thoracic aorta of patients. Kaplan–Meier survival curves and Cox regression were used to examine the predictive significance of corrected baseline metabolic parameters on 3-year PFS of patients. The incremental values of corrected baseline metabolic parameters were evaluated by using Harrell's C-indices, receiver operating characteristic, and Decision Curve Analysis.
Results The multivariate analysis revealed that only the National Comprehensive Cancer Network (NCCN)-International Prognostic Index (IPI) and corMTVsum had an effect on 3-year PFS of patients (p < 0.05, respectively). The Kaplan–Meier survival analysis demonstrated significant differences in PFS between the risk groups classified by corSUVsum, corMTVsum, and corTLGtotal (log-rank test, p < 0.05). The predictive model composed of corMTVsum and corTLGtotal surpasses the predictive performance of the model incorporating MTVsum and TLGtotal. The optimal performance was observed when corMTVsum was combined with NCCN-IPI, resulting in a Harrell's C index of 0.785 and area under the curve values of 0.863, 0.891, and 0.947 for the 1-, 2-, and 3-year PFS rates, respectively.
Conclusion The corMTVsum offers significant prognostic value for patients with DLBCL. Furthermore, the combination of corMTVsum with the NCCN-IPI can provide an accurate prediction of the prognosis.
Standardizing Normal Reference Value for Thyroid Uptake of Technetium-99m Pertechnetate in Nepalese Population
Authors: Paudel Jiwan , Bhattarai Babita 
Published: February 2024

Abstract
Objective Changes in normal reference values of thyroid uptake for iodine have been reported due to geographical and chronological fluctuations in dietary iodine intake in different populations. Nepal is a country with mixed ethnicity, with access to dietary iodine in the form of successful universal salt iodination program by the government of Nepal since 1973. The aim of this study was to establish the normal reference values for thyroid uptake of technetium-99m (Tc-99m) pertechnetate in the Nepalese population in iodine sufficiency era.
Methods We prospectively evaluated 52 clinically and biochemically euthyroid participants (46 females and 6 males) with age range from 20 to 71 years who underwent a thyroid Tc-99m pertechnetate scan and uptake between December 2019 to November 2023 in the Department of Nuclear Medicine, Chitwan Medical College fulfilling inclusion/exclusion criteria. Biochemical thyroid function tests were reviewed and Tc-99m pertechnetate thyroid uptake values were determined for each patient. Blood was withdrawn for thyroid hormone assessment. Euthyroid participants were then administered 3.5 to 4.5 mCi of Tc-99m pertechnetate intravenously and their percentage thyroid uptake was calculated after 20 minutes.
Results The mean and median uptake of Tc-99m pertechnetate in euthyroid patients were 1.26 and 0.85%, respectively, and the interquartile range was 0.7 to 1.7%. The normal reference uptake value for Tc-99m pertechnetate in the studied population ranged between 0.3 and 3.6%. The fifth and 95th percentiles for pertechnetate uptake were 0.5 and 2.9%, respectively.
Conclusion The normal reference range for Tc-99m pertechnetate thyroid uptake in Nepalese population was 0.5 to 2.9% that is lower than the currently accepted international standard of 0.75 to 4.5%. Uptake also increased with increasing age. This study highlights the importance of periodically redefining the geographic location specific normal thyroid uptake reference values.
Politics, religion, and drama
Authors: Gillings Mathew 
Published: February 2024

Abstract
This chapter explores the metapragmatics of hypocrisy by taking a corpus-based approach to analysis.
Specifically, the paper focuses on examining which social actors are labelled as hypocrites, what situations
accusations of hypocrisy tend to occur in, and how language is used to construct people’s understanding of what
hypocrisy is. To achieve this, instances of the lemma hypocrisy are examined within the Times Online
2000s corpus. Collocation analysis is used to explore the discourses in which the lemma is found, and as
a result six broad categories are identified: social actors; religion and morality; society, social issues and
justice; class system; drama; and metaphors. Exploration of these collocates and their respective concordance lines
helps to further the understanding of this complex phenomenon, and it goes some way towards bridging the gap between
traditional deception theory stemming from social psychology, and more recent empirical work within pragmatics.
Ostensible offers, politeness and sincere hypocrisy
Authors: Haugh Michael 
Published: February 2024

Abstract
We know that sometimes when people make an offer they do not really expect us to take it up. It is generally
assumed that these kinds of ostensible offers are a means of showing respect or consideration towards the feelings of
others, without creating the trouble or imposition that actually acting upon that offer might entail for all the
parties concerned. Yet despite the complex questions ostensible offers and other kinds of ostensible actions raise for
theories of politeness, (in)sincerity and hypocrisy have received only passing attention in (im)politeness research.
In this chapter, I reflect on the relationship between (in)sincerity, hypocrisy and politeness in the context of
ostensible offers. I consider how participants recognise ostensible offers, what kinds of off-record purposes are
accomplished when offers are treated as ostensible (rather than genuine), and why they are interpretable as polite
rather than hypocritical. Drawing on an analysis of instances of ostensible and genuine offers identified in initial
interactions in English between previously unacquainted interactants, I suggest that what lies at the heart of
politeness in the case of ostensible offers is sincere hypocrisy. That is, while the speaker making the offer may not
expect the recipient to (genuinely) accept that offer, they do nevertheless expect the recipient will recognise the
purpose of making that offer is not to be disingenuous, but rather to show consideration for the feelings of the
recipient. I conclude by suggesting that sincere hypocrisy is not limited to ostensible offers, but is arguably a
pervasive characteristic of much of what passes as politeness more generally.
The – mostly – brighter side of hypocrisy and the concept of face
Authors: O’Driscoll Jim 
Published: February 2024

Abstract
This chapter considers the relation between hypocrisy and the concept of face. It is argued that face is an
ideal lens through which to view both the inevitability of hypocrisy and also its various hues. This inevitability is
the result of the unavoidability of face in interaction. Face is more than an affective attribute to which homage must
be paid. It is the essential means without which most communication would grind to a halt, and in that facework
involves interactants giving off impressions of themselves and forming impressions of others present which may not be
correct, there is a sense in which face makes hypocrites of us all. Examples of this accidental and essentially
beneficial hypocrisy are analysed in support of this argument. The chapter then proceeds to an example of the more
obviously beneficial facet of hypocrisy, when it is used to save and/or enhance people’s faces. A subsequent brief
consideration of hypocrisy in speech acts again finds that it has positive social value.
What affective rupture does. Disrupting affective citizenship in migrant solidarity
Authors: Lampredi Giacomo 
Published: February 2024

ABSTRACT
The aim of this paper is to show how emotions and citizenship are inextricably intertwined in the analysis of migrant solidarity. It does so by highlighting the ‘disrupting’ dimensions of emotions as processes that redefine the very criteria by which one is included or excluded, close or distant, intimate or foreign, in every situation. The essay draws on ethnographic research with Italian citizens doing solidarity work for and with migrants in Florence and Turin. Solidarity practices and the emotions that constitute them are important for the production of lived citizenship, which happens on a daily basis. By discussing results that emerged through qualitative methods, the essay has the aim to investigate the role of affective ruptures in migrant solidarity networks, and how they may be emotional and reflexive turning points that transform the ethical-political attitudes.
Mode stability for gravitational instantons of type D
Authors: Nilsson Gustav 
Published: February 2024

Abstract
We study Ricci-flat perturbations of gravitational instantons of Petrov type D. Analogously to the Lorentzian case, the Weyl curvature scalars of extreme spin weight satisfy a Riemannian version of the separable Teukolsky equation. As a step toward infinitesimal rigidity of the type D Kerr and Taub-bolt families of instantons, we prove mode stability, i.e. that the Teukolsky equation admits no solutions compatible with regularity and asymptotic (local) flatness.

Ultra-thin double-layered hexagonal CuI: strain tunable properties and robust semiconducting behavior
Authors: Demirok A C , Sahin H , Yagmurcukardes M 
Published: February 2024

Abstract
In this study, the freestanding form of ultra-thin CuI crystals, which have recently been synthesized experimentally, and their strain-dependent properties are investigated by means of density functional theory calculations. Structural optimizations show that CuI crystallizes in a double-layered hexagonal crystal (DLHC) structure. While phonon calculations predict that DLHC CuI crystals are dynamically stable, subsequent vibrational spectrum analyzes reveal that this structure has four unique Raman-active modes, allowing it to be easily distinguished from similar ultra-thin two-dimensional materials. Electronically, DLHC CuI is found to be a semiconductor with a direct band gap of 3.24 eV which is larger than that of its wurtzite and zincblende phases. Furthermore, it is found that in both armchair (AC) and zigzag (ZZ) orientations the elastic instabilities occur over the high strain strengths indicating the soft nature of CuI layer. In addition, the stress–strain curve along the AC direction reveal that DLHC CuI undergoes a structural phase transition between the 4% and 5% tensile uniaxial strains as indicated by a sudden drop of the stress in the lattice. Moreover, the phonon band dispersions show that the phononic instability occurs at much smaller strain along the ZZ direction than that of along the AC direction. Furthermore, the external strain direction can be deduced from the predicted Raman spectra through the splitting rates of the doubly degenerate in-plane vibrations. The mobility of the hole carriers display highly anisotropic characteristic as the applied strain reaches 5% along the AC direction. Due to its anomalous strain-dependent electronic features and elastically soft nature, DLHC of CuI is a potential candidate for future electro-mechanical applications.

Authors: Roy Arijit , Ghosal Munmun , Mallick Abhishek , Roy Durjoy , Biswas Bidisha 
Published: February 2024

Abstract
Measurement of self-inductance and mutual-inductance has been demonstrated as a laboratory experiment with great simplicity. The novelty of this demonstration lies in its straightforward circuitry and methodology, enabling the experiment accessible to students with minimal prerequisite knowledge. A coil-pair setup was constructed using discarded common household articles, costing very low but provides high quality throughput in teaching-learning experience. The demonstration can be easily conducted online using a laptop without the need of extra power supply. The experiment suits for high school and pre-university students, as evident by twenty first-semester undergraduate physics and electronics students who found it both satisfying and enjoyable with a relatively flat learning curve.

Published: February 2024

Abstract
In this paper, a device is introduced to enlarge micro deformation of steel wire by using Moire fringe formed by double grating, and then measure the Young modulus. Since the angle of the double grating in the device is difficult to control accurately, and it is difficult to accurately achieve the desired magnification, we chose to calculate the magnification by measuring the width of the Moire fringe, and then conducted subsequent measurement. The experimental device proposed in this article has a simple structure and low cost, and can be used as a combination of optical and mechanics experiment content for undergraduate students.
Transient striations in an inductively coupled plasma during E-to-H transitions
Authors: Gu Meng-Zhi , Lei Zhi-Cheng , Zhang Xuan , Pu Yi-Kang 
Published: February 2024

Abstract
Azimuthal transient striations are reported for inductively coupled Ar plasma during E-to-H transition at 200 mTorr. In this transient process, the number of striations increases with time, and striations ultimately disappear when the H mode is reached. An integrated model is developed to investigate the mechanism of this phenomenon. This integrated model incorporates a one-dimensional time-dependent fluid model with a perturbation analysis, as well as a circuit model for power coupling with the external radio-frequency driving source. Based on this integrated model, the development of striations is proposed to be a consequence of ionization instability due to the variation in the electron energy distribution function. The model results for the temporal evolution of the number of striations are in good agreement with the observed data.
Classical-quantum dual encoding for laser communications in space
Authors: Winnel Matthew S , Wang Ziqing , Malaney Robert , Aguinaldo Ryan , Green Jonathan , Ralph Timothy C 
Published: February 2024

Abstract
In typical laser communications classical information is encoded by modulating the amplitude of the laser beam and measured via direct detection. We add a layer of security using quantum physics to this standard scheme, applicable to free-space channels. We consider a simultaneous classical-quantum communication scheme where the classical information is encoded in the usual way and the quantum information is encoded as fluctuations of a sub-Poissonian noise-floor. For secret key generation, we consider a continuous-variable quantum key distribution protocol (CVQKD) using a Gaussian ensemble of squeezed states and direct detection. Under the assumption of passive attacks secure key generation and classical communication can proceed simultaneously. Compared with standard CVQKD, which is secure against unrestricted attacks, our added layer of quantum security is simple to implement, robust and does not affect classical data rates. We perform detailed simulations of the performance of the protocol for a free-space atmospheric channel. We analyse security of the CVQKD protocol in the composable finite-size regime.
Enhancement in thermoelectric performance of hydrothermally synthesized Ca and Sb co-doped Bi2Te3 nanostructures
Authors: Rani Kavita , Gupta Vivek , Dalal Ranjeet , Pandey Abhishek 
Published: February 2024

Abstract

−Ca & Sb co-doped Bi2Te3 compounds have been prepared by hydrothermal method at 210 °C for 24 h and investigated their thermoelectric properties. Phase purity and crystallinity were analyzed by XRD. All the prepared samples have rhombohedral crystal structure with space group R-3m. The hexagonal nanoplate-like morphology was examined by FESEM. Elemental analysis was done with EDX. Band gap energy of prepared samples has values in the range of ∼0.40–0.65 eV, obtained by Tauc plot. The Raman shift was obtained at a lower frequency with doping. Carrier concentration increased with doping from 3.18 × 1020 cm−1 to 9.34 × 1020 cm−1. The high value of power factor (PF) of ∼10.8 × 10–4 Wm−1K−2 was obtained due to high carrier concentration. An ultralow lattice thermal conductivity of ∼0.28 and ∼0.63 W mK−1 at 420 K, was obtained for Ca0.06Bi1.88Sb0.06Te3 and pure Bi2Te3, respectively. A maximum ZT of ∼0.78 at 386 K was obtained for Ca0.03Bi1.94Sb0.03Te3. The value of ZT thus obtained is about ∼ 51% higher than the ZT of pure Bi2Te3 (∼0.39 at 386 K).
