ABSTRACT
The lack of genetically diverse preclinical animal models in basic biology and efficacy testing has been cited as a potential cause of failure in clinical trials. We developed and characterized five diverse RAG1 null mouse strains as models that allow xenografts to grow. In these strains, we characterized the growth of breast cancer, leukemia and glioma cell lines. We found a wide range of growth characteristics that were far more dependent on strain than tumor type. For the breast cancer cell line, we characterized the spectrum of xenograft/tumor growth at structural, histological, cellular and molecular levels across each strain, and found that each strain captures unique structural components of the stroma. Furthermore, we showed that the increase in tumor-infiltrating myeloid CD45+ cells and the amount of circulating cytokine IL-6 and chemokine KC (also known as CXCL1) is associated with a higher tumor size in different strains. This resource is available to study established human xenografts, as well as difficult-to-xenograft tumors and growth of hematopoietic stems cells, and to decipher the role of myeloid cells in the development of spontaneous cancers.

Published: August 2022

Abstract
Novel UV-curable bio-based polymers were prepared from cashew nut shell liquid (CNSL), a natural phenol compound, at room temperature via thiol-ene reaction. The physical, thermal, optical, and mechanical properties of UV-cured polymers and the structure-property relationship of these materials were investigated. The resultant UV-cured polymers showed flexibility, transparency with high gloss, thermal resistance, and long-term stability as compared with other CNSL-based polymers. This is because the one step UV-click thiol-ene reaction from transparent CNSL-derived monomer proceeded effectively between S-H and C=C of allyl and alkyl sidechains, leading to a much more highly flexible crosslinked structure. This UV-curable bio-based polymer can be very advantageous in application of flexible coating and film.

High-quality 8-fold self-compression of ultrashort near-UV pulses in an Ar-filled ultrathin-walled photonic crystal fiber
Authors: Luan Jie , Russell Philip St.J. , Novoa David 
Published: August 2022

We demonstrate generation of 7.6 fs near-UV pulses centered at 400 nm via 8-fold soliton-effect self-compression in an Ar-filled hollow-core kagomé-style photonic crystal fiber with ultrathin core walls. Analytical calculations of the effective compression length and soliton order permit adjustment of the experimental parameters, and numerical modeling of the nonlinear pulse dynamics in the fiber accurately predicts the spectrotemporal profiles of the self-compressed pulses. After compensation of phase distortion introduced by the optical elements along the beam path from the fiber to the diagnostics, 71% of the pulse energy was in the main temporal lobe, with peak powers in excess of 0.2 GW. The convenient setup opens up new opportunities for time-resolved studies in spectroscopy, chemistry, and materials science.

Purpose
In addition to estimating the prevalence of intentional abortion in Iranian female sex workers (FSWs), this study identified related factors using the data of a national study.

Methods
This cross-sectional study utilizes the third round of integrated bio-behavioral surveillance-III data in Iranian FSWs in December 2019 and August 2020, and 1515 Participants were selected in 8 geographically diverse cities in Iran. Logistic regression was performed using unweighted analysis to identify factors associated with intentional abortion. Stata software (version 14), respondent-driven sampling analyses, and R (version 4.1.2) was used for data analysis.

Results
From 1390 participants with valid responses to the abortion question, 598 (37.3%; 95% CI: 32.43, 42.11%) reported intentional abortion during their life. According to the age groups, the highest prevalence of abortion was in the age group of 31 to 40 years (42.60%). In the multivariate logistic regression model, the marital status (divorced women (AOR = 2.05, 95% CI: 1.29, 3.27), concubines (AOR = 1.78, 95% CI: 1.02, 3.11)), work experience in brothels (AOR = 1.39, 95% CI: 1.04, 1.84), the type of sex (AOR = 2.75, 95% CI: 1.35, 5.58), the history of sexual violence (AOR = 1.54, 95% CI: 1.19, 2.01), and alcohol consumption (AOR = 1.53, 95% CI: 1.18, 2.01) were significantly associated with a history of intentional abortion.

Conclusion
Intentional abortion’s prevalence among Iranian FSWs has been much higher than that of the general female population in Iran, which is an alarming issue in the public health of this group and needs more effective interventions. In addition, alcohol consumption, working in a brothel, and being divorced are essential factors in increasing abortions among sex workers.
In Moonlight, Perpetually Outside
Authors: Wooden Isaiah Matthew 
Published: August 2022

Abstract
This article explores the ways the Academy Award-winning film Moonlight reveals and reflects a Black spatial imaginary that explicitly and inextricably links Blackness, queerness, and the outside. In sharpening focus on its central character's journey from bullied kid to alienated high school student to hardened twenty-something, Moonlight, I argue, repudiates many of the anti-Black premises that vitalize the project of white supremacy and the white spatial imaginary, particularly those that cast Black people as always already unfit or unworthy—of freedom, of intimacy, of pleasure, of life. Simultaneously, the film draws attention to and invites viewers to grapple with the ways that Blackness always already indexes a waywardness, a transience, a queerness, a “movement in excess” that is itself an instantiation and expression of refusal, a being in and for the outside.

Practical application of European biological variation combined with Westgard Sigma Rules in internal quality control
Authors: Song Zhenzhen , Zhang Jiajia , Liu Bing , Wang Hao , Bi Lijun , Xu Qingxia 
Published: August 2022

Abstract

Objectives
Westgard Sigma Rules is a statistical tool available for quality control. Biological variation (BV) can be used to set analytical performance specifications (APS). The European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) regularly updates BV data. However, few studies have used robust BV data to determine quality goals and design a quality control strategy for tumor markers. The aim of this study was to derive APS for tumor markers from EFLM BV data and apply Westgard Sigma Rules to establish internal quality control (IQC) rules.

Methods
Precision was calculated from IQC data, and bias was obtained from the relative deviation of the External quality assurance scheme (EQAS) group mean values and laboratory-measured values. Total allowable error (TEa) was derived using EFLM BV data. After calculating sigma metrics, the IQC strategy for each tumor marker was determined according to Westgard Sigma Rules.

Results
Sigma metrics achieved for each analyte varied with the level of TEa. Most of these tumor markers except neuron-specific enolase reached 3σ or better based on TEamin. With TEades and TEaopt set as the quality goals, almost all analytes had sigma values below 3. Set TEamin as quality goal, each analyte matched IQC muti rules and numbers of control measurements according to sigma values.

Conclusions
Quality goals from the EFLM BV database and Westgard Sigma Rules can be used to develop IQC strategy for tumor markers.
Interior reconstruction in tomography via prior support constrained compressed sensing
Authors: Sonkar Munnu , Najiya K. Z. , Sastry C. S 
Published: August 2022

Abstract
Local reconstruction from localized projections attains importance in Computed Tomography (CT). Several researchers addressed the local recovery (or interior) problem in different frameworks. The recent sparsity based optimization techniques in Compressed Sensing (CS) are shown to be useful for CT reconstruction. The CS based methods provide hardware-friendly algorithms, while using lesser data compared to other methods. The interior reconstruction in CT, being ill-posed, in general admits several solutions. Consequently, a question arises pertaining to the presence of target (or interior-centric) pixels in the recovered solution.
In this paper, we address this problem by posing the local CT problem in the prior support constrained CS framework.
In particular, we provide certain analytical guarantees for the presence of intended pixels in the recovered solution,
while demonstrating the efficacy of our method empirically.
Ecolinguistics: History, today, and tomorrow
Authors: Penz Hermine , Fill Alwin 
Published: August 2022

AbstractSince the concept of ecology was first applied to language over 50 years ago, the field of ecolinguistics has developed into a thriving branch of linguistics that is more than ever closer to the pressing issues of our time. This article aims to trace the historical development of ecolinguistics, discusses the main trends in current research, and provides a brief projection of potential future developments. The first part includes an overview of research connected to Einar Haugen’s article “Ecology of Language”, published in 1972, which focuses on the interaction between languages in multilingual contexts. A large part of the article is then devoted to the role of language in dealing with environmental problems (e.g. aggravating or solving them), which is the biological understanding of ecology in the study of language inspired by Halliday’s 1990 talk “New Ways of Meaning: The Challenge to Applied Linguistics”. Ecolinguistics will certainly have an interesting future. It will take up topics such as climate change, which surprisingly has largely been excluded from ecolinguistic research until recently. Other topics that need to be dealt with are the negative effects of tourism, the migration of human, plant, and animal populations. Ecolinguists, in the future, will also expand their methodology towards multimodal research and study how non-European languages present the ‘environment’, or rather ‘con-vironment’.
Like a shark in the ocean: the semiotics of extreme precarity in Joshua Tree rock climbing
Authors: Ness Sally Ann 
Published: August 2022

Abstract
During the mid-1970s the extraordinarily dangerous style of free solo climbing (climbing without protection) emerged in the collective practice of a small community of “Stonemaster” climbers actively developing new climbing routes and the new “free” style of roped climbing in what is now Joshua Tree National Park, California. While its emergence might be interpreted as an affectively-driven, macho embodied social semiotic or ethnomotricity, in actuality the evolution of free soloing in the case of Stonemaster-era climbing at Joshua Tree may be more accurately understood as the logical consequence of an intensive regime of practice in which climbers developed a near absolute bodily familiarity with certain climbing routes. Eventually, the reasonableness of climbing with little and even no protection on a subset of these routes became self-evident and conventional. Free soloing, in the semiotic perspective of the later Peirce, manifested as a Normal Logical Interpretant in the Joshua Tree landscape. It embodied the living definition of self-controlled conduct, and the Symbols it cultivated testified persuasively to the growth of a creative corporeal intelligence actualizing near absolute degrees of free will.

Published: August 2022

Zusammenfassung
Es wird ein physikalisches und methodisches Konzept vorgeschlagen, das auf der Anwendung eines phononischen Kristalls zur Manipulation und Detektion heterogener Flüssigkeit in einem Kanal basiert. Der phononische Kristall wurde aus einem Edelstahlblock mit einer periodischen Struktur aus zylindrischen Löchern hergestellt. Ein Defekt der periodischen Struktur in Form eines flüssigkeitsgefüllten Kanals wurde in die Mitte des phononischen Kristalls gelegt. Die akustische Defekteigenmode wurde auf den Bandlückenfrequenzbereich des phononischen Kristalls abgestimmt. Eine wandernde akustische Welle wurde entlang des Defekthohlraums gestartet, um die heterogene Flüssigkeit zu manipulieren, und über den Hohlraum wurde eine lokale Schallsondierung der Zusammensetzung der Flüssigkeit mit Schallgeschwindigkeit durchgeführt. Als Beispiel für eine heterogene Flüssigkeit wurde Milch gewählt.
In-Situ Measurements of the Physiological Parameters in Lab-on-Chip Systems

Published: August 2022

Zusammenfassung
Es ist von höchster wissenschaftlicher Relevanz, Biosensoren in Lab-on-Chip-Systeme zu integrieren. Die Integration der Sensoren in die Zellkultursysteme ermöglicht die direkte Messung der biologischen und physiologischen Parameter während des Zellwachstums. Es erfordert ein spezielles Design des mikrofluidischen Chips und eine Mikrostrukturierung der leitfähigen Materialien. In dieser Arbeit präsentieren wir zwei Ansätze für in-situ Messungen von physiologischen Parametern. Der erste ist eine Integration eines kommerziellen optischen Sensors für die Sauerstoffgehaltsdetektion und der zweite ist ein eigener, von uns entworfener und hergestellter transepithelialer Widerstandssensor (TEER) für Zellkonfluenzmessungen. Beide Sensoren wurden in einen flexiblen Mikrofluidik-Chip auf Basis von Polydimethylsiloxan (PDMS) integriert.
Ein Bottom-up Ansatz für die Radius- und Rundheitsmessung von Mikrokugeln
Authors: Oertel Erik , Manske Eberhard 
Published: August 2022

Zusammenfassung
Die mangelnde Verfügbarkeit von präzise charakterisierten Kugeln im Submillimeterbereich schränkt derzeit die Leistungsfähigkeit von Mikro- und Nano-Koordinatenmessgeräten ein. Aus diesem Grund werden am Institut für Prozessmess- und Sensortechnik der TU Ilmenau neue Ansätze zur Messung solcher Kugeln untersucht und daraus entsprechende Messverfahren entwickelt. Ein vielversprechender Ansatz basiert dabei auf einer Reihe von Oberflächenscans im Zusammenhang mit einem Stitching-Algorithmus. Als Oberflächensensor kommt zur Zeit ein Atomkraftmikroskop (AFM) im Kontaktmodus zum Einsatz. Eine rückführbare Messung erfordert eine präzise Charakterisierung der AFM-Spitzenform und deren Unsicherheit, um diesen Einfluss zu korrigieren und die Unsicherheit fortzupflanzen sowie möglichen Verschleiß der AFM-Spitze während des Messvorgangs festzustellen. Diese Aspekte fanden bisher keine Beachtung. Ausgehend von dem publizierten Stand wurde deshalb die Messstrategie und der Auswertealgorithmus durch eine geeignete Strategie zur Korrektur des Spitzenformeinflusses sowie der Ermittlung der Spitzenform erweitert. Diese wurde experimentell durch den Einsatz unterschiedlicher AFMSpitzen mit nominellen Radien von 100nm bis 2 μm an einer 300 μm-Rubin-Kugel untersucht. Im Rahmen des Beitrags werden dazu erste Ergebnisse vorgestellt und diskutiert.

(3) (bbp = bis(2-benzimidazolyl)pyridine dianion, Chxn = 1,2-diaminocyclo hexane, cyclam = 1,4,8,11-tetraazacyclodecane) have been assembled from the rarely used mer-tricyanidoiron(III) building block [PPh4]2[Fe(bbp)(CN)3] and three copper(II) compounds. The complexes have been characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. For the chiral enantiomers 1 and 2, the circular dichroism (CD) spectrum was also investigated. X-ray structural analyses revealed that the structures of the cyanide-bridged Fe-Cu complexes 1 and 2 are characterized by two crystallographically independent but structurally very similar homochiral neutral chains, each consisting of the repeating units {[Cu(S,S-Chxn)2][Fe(bbp)(CN)3]} (1) or {[Cu(R,R-Chxn)2][Fe(bbp)(CN)3]} (2). The crystal structure of 3 likewise is build up of chains consisting of {[Cu(Cyclam)][Fe(bbp)(CN)3]} building blocks. The temperature-dependent magnetic susceptibility and field dependent magnetization of the complexes showed antiferromagnetic interactions in complex 1 between the Fe(III) and Cu(II) ions, while complex 3 is ferromagnetic, indicating that the magnetic coupling through cyanide linkage is very sensitive to the structure parameters around the paramagnetic metal ions. These results have been further confirmed by fitting of the experimental data using a uniform chain model, leading to the coupling constants J = −6.35 cm−1, g = 2.08, R = 4.42 × 10−4 and J = 1.24 cm−1, g = 2.09, R = ∑(χ
