Walking-With Landscape
Authors: Einarsdóttir Elva Björg , Lund Katrín Anna 
Published: October 2023

AbstractIn this chapter, we consider the process of walking with landscape, underlining the importance of recognising more-than-human intimacy in proximity tourism. We set out with a small group from Reykjavík, Iceland that headed off on a tour in the north-western countryside to walk together with nature and each other. We seek to examine how, whilst walking, the surroundings themselves demand to be acknowledged as vital agents and direct participants of the walk, and we examine how the group needed to tune into the rhythms of the landscape, considering its flora, fauna, and earthly qualities, as well as the narratives that emerged as the walk continued, sometimes surprising and even confronting but constantly shifting the rhythms of the walk and shaping its atmospheres. By doing so, we demonstrate how different terrains evoke different proximities, sensations, and thoughts alongside a number of spatial and temporal connections that affect the rhythms of the body in the landscape with its outermost feelings and sensations.
Weakly Nonlinear Time Invariant Circuits
Authors: Beffa Federico 
Published: October 2023

AbstractThe aim of this chapter is to show the utility of the theory that we developed. This is done by applying it to the analysis of nonlinear effects, that is of deviation from linear behaviour, in analog circuits. The vast majority of analog circuits are limited by noise on the bottom end of their dynamic range and by nonlinear effects on the upper end.
Periodically Switched Circuits
Authors: Beffa Federico 
Published: October 2023

AbstractThis chapter is devoted to illustrating applications of the theory of weakly nonlinear time-varying systems with practical examples. After introducing the class of electrical networks called switched circuits, we analyse in details some instantiations. We analyse a practical implementation of a quadrature modulator, including its distortion and other aspects of fundamental importance in applications. As another example of the usefulness of time-varying circuits, we illustrate how they allow implementing highly selective filters that are otherwise unfeasible in small integrated form.
Distributions
Authors: Beffa Federico 
Published: October 2023

AbstractWe investigate the mathematical description of signals that are commonly used in the analysis of technical problems. From a mathematical point of view it would be useful to limit the signals of interest to the set of continuous functions. However, this has several disadvantages. For example, suppose we are interested in the transient response of, say, a series RC low-pass-filter (LPF) to an input step voltage.
“Don’t Expect the Wrong Things from Institutions.”—Berno Odo Polzer Interviewed by Christian Grüny
Authors: Odo Polzer Berno , Grüny Christian 
Published: October 2023

AbstractIn an interview with Christian Grüny, Polzer discusses the politics of time and listening. His approach as artistic director of the MaerzMusik festival at the Berliner Festspiele focussed on situating contemporary music and sound practices within an interdisciplinary and sociopolitical landscape, investing a unique level of care into the relation between musical programming and its contextualisation. To this end, Polzer emphasises fostering forms of collectivity and communality as the site of production of musical meaning, while also checking the often-hyperbolic claims that arts institutions make regarding their value to society.
Institutions Against Art Music—Curation, Rehearsal, and Contemporary Art
Authors: Barrett G Douglas 
Published: October 2023

AbstractThis chapter analyses the work of contemporary artists who use alternative institutions to challenge accepted notions of art music. Kevin Beasley’s 2019 curatorial collaboration with The Kitchen, Assembly, reframes heterogeneous musics as contemporary art through the transformational act of curation. In Rehearsing Philadelphia (2022), Ari Benjamin Meyers displays the process of musical rehearsal within temporary music organisations. The chapter contends that whereas Meyers devalues a range of music by refiguring it as rehearsal, Beasley and The Kitchen transvaluate musical practices historically understood as nonart into contemporary art—and, potentially, into art music—via the powers of the curator. Beyond calls to throw out labels and categories, such projects turn on the concrete determination of what art music is while implicating contemporary art in its potential critical reconstruction.
Interfacial Phenomena in Adhesion and Adhesive Bonding Investigated by Electron Microscopy
Authors: Horiuchi Shin 
Published: October 2023

AbstractUsing electron microscopy techniques described in Chap. 2, we investigate interfacial phenomena in adhesion and adhesive bonding. Polymer–polymer interfaces formed via interdiffusion are visualized and characterized by EFTEM. Fractographic studies using high-resolution SEM investigate entanglements at the polymer–polymer interfaces, and the adhesion mechanism is discussed about the interfacial entanglements. The effect of surface treatments of polymers for adhesion improvement is studied in terms of the surface roughness and the chemical functionality of the adherend created by the surface pretreatments. We then describe the role of chemical interactions between polymers and metals on bonding by the analysis of fracture surfaces by the STEM-replica technique. Bonding mechanisms of adhesive bonding and recently developed direct bonding of metal and plastic are also investigated by STEM-EELS/ELNES and STEM-tomography. Finally, we evaluate the toughness and durability of adhesive joints between metal and carbon fiber reinforced plastics (CFRP) and discuss the durability of the adhesive bonding.
Power corrections to energy flow correlations from large spin perturbation
Authors: Chen Hao , Zhou Xinan , Zhu Hua Xing 
Published: October 2023

AbstractDynamics of high energy scattering in Quantum Chromodynamics (QCD) are primarily probed through detector energy flow correlations. One important example is the Energy-Energy Correlator (EEC), whose back-to-back limit probes correlations of QCD on the lightcone and can be described by a transverse-momentum dependent factorization formula in the leading power approximation. In this work, we develop a systematic method to go beyond this approximation. We identify the origin of logarithmically enhanced contributions in the back-to-back limit as the exchange of operators with low twists and large spins in the local operator product expansion. Using techniques from the conformal bootstrap, the large logarithms beyond leading power can be resummed to all orders in the perturbative coupling. As an illustration of this method, we perform an all-order resummation of the leading and next-to-leading logarithms beyond the leading power in$$ \mathcal{N} $$N= 4 Super Yang-Mills theory.
Forward production of prompt neutrinos from charm in the atmosphere and at high energy colliders
Authors: Bai Weidong , Diwan Milind , Garzelli Maria Vittoria , Jeong Yu Seon , Kumar Karan , Reno Mary Hall 
Published: October 2023

Abstract
The high-energy atmospheric neutrino flux is dominated by neutrinos from the decays of charmed hadrons produced in the forward direction by cosmic ray interactions with air nuclei. We evaluate the charm contributions to the prompt atmospheric neutrino flux as a function of the center-of-mass energy $$ \sqrt{s} $$

s

of the hadronic collision and of the center-of-mass rapidity y of the produced charm hadron. Uncertainties associated with parton distribution functions are also evaluated as a function of y. We find that the y coverage of LHCb for forward heavy-flavour production, complemented by the angular coverage of present and future forward neutrino experiments at the LHC, bracket the most interesting y regions for the prompt atmospheric neutrino flux. At $$ \sqrt{s} $$

s

= 14 TeV foreseen for the HL-LHC phase, nucleon collisions in air contribute to the prompt neutrino flux prominently below Eν ~ 107 GeV. Measurements of forward charm and/or forward neutrinos produced in hadron collisions up to $$ \sqrt{s} $$

s

= 100 TeV, which might become possible at the FCC, are relevant for the prompt atmospheric neutrino flux up to Eν = 108 GeV and beyond.

Global symmetry-breaking and generalized theta-terms in Type IIB EFTs
Authors: Grimm Thomas W. , Lanza Stefano , van Vuren Thomas 
Published: October 2023

Abstract
A longstanding conjecture states that global symmetries should be absent in quantum gravity. By investigating large classes of Type IIB four-dimensional $$ \mathcal{N} $$
N
= 2 effective field theories, we enlist the potential generalized global symmetries that could be present and explore how they are avoided. Crucial ingredients that arise in such effective field theories are generalized θ-terms. These introduce non-linear couplings between axion fields and topological terms quadratic in the gauge field strengths which break a large subset of the global symmetries. Additional residual global symmetries may further be broken by assuming the existence of some charged states. However, we illustrate that the presence of generalized θ-terms leads to a generalized Witten effect, which implies that the spectrum of charged states is constituted by an infinitely populated lattice. We further show that such a lattice is generated by the action of the monodromy transformation that characterizes the moduli space boundary near which the effective theory is defined.
From 5d flat connections to 4d fluxes (the art of slicing the cone)
Authors: Lundin Jim , Mauch Roman , Ruggeri Lorenzo 
Published: October 2023

Abstract
We compute the Coulomb branch partition function of the 4d $$ \mathcal{N} $$
N
= 2 vector multiplet on closed simply-connected quasi-toric manifolds B. This includes a large class of theories, localising to either instantons or anti-instantons at the torus fixed points (including Donaldson-Witten and Pestun-like theories as examples). The main difficulty is to obtain flux contributions from the localisation procedure. We achieve this by taking a detour via the 5d $$ \mathcal{N} $$
N
= 1 vector multiplet on closed simply-connected toric Sasaki-manifolds M which are principal S1-bundles over B. The perturbative partition function can be expressed as a product over slices of the toric cone. By taking finite quotients M/ℤh along the S1, the locus picks up non-trivial flat connections which, in the limit h → ∞, provide the sought-after fluxes on B. We compute the one-loop partition functions around each topological sector on M/ℤh and B explicitly, and then factorise them into contributions from the torus fixed points. This enables us to also write down the conjectured instanton part of the partition function on B.

Abstract
Purpose
Occlusions of the internal carotid artery (ICA) may be caused by dissection, embolic or macroangiopathic pathogenesis, which partially influences the treatment; however, inferring the underlying etiology in computed tomography angiography can be challenging. In this study, we investigated whether computed tomography perfusion (CT-P) parameters could be used to distinguish between etiologies.

Methods
Patients who received CT‑P in acute ischemic stroke due to ICA occlusion between 2012 and 2019 were retrospectively analyzed. Group comparisons between etiologies regarding the ratios of CT‑P parameters between both hemispheres for relative cerebral blood volume (rCBV), relative cerebral blood flow (rCBF), time to maximum (Tmax), and mean transit time (MTT) were calculated by one-factorial analysis of variance (ANOVA) and compared by pairwise Bonferroni post hoc tests. An receiver operating characteristics (ROC) analysis was performed if differences in group comparisons were found. Multinomial logistic regression (MLR) including pretherapeutic parameters was calculated for etiologies.

Results
In this study 69 patients (age = 70 ± 14 years, dissection = 10, 14.5%, embolic = 19, 27.5% and macroangiopathic = 40, 58.0%) were included. Group differences in ANOVA were only found for MTT ratio (p = 0.003, η2 = 0.164). In the post hoc test, MTT ratio showed a differentiability between embolic and macroangiopathic occlusions (p = 0.002). ROC analysis for differentiating embolic and macroangiopathic ICA occlusions based on MTT ratio showed an AUC of 0.77 (p < 0.001, CI = 0.65–0.89) and a cut-off was yielded at a value of 1.15 for the MTT ratio (sensitivity 73%, specificity 68%). The MLR showed an overall good model performance.

Conclusion
It was possible to differentiate between patients with embolic and macroangiopathic ICA occlusions based on MTT ratios and to define a corresponding cut-off. Differentiation from patients with dissection versus the other etiologies was not possible by CT‑P parameters in our sample.

Published: October 2023

AbstractPurposeKnees with unicompartmental varus osteoarthritis (OA) usually display a combination of tibiofemoral bony deformity and increased joint line convergence angle (JLCA). The JLCA is a product of intra‐articular deformity and lateral soft tissue laxity. This study aims to define the correlation between the JLCA and progression of OA.MethodsA retrospective radiological analysis of 501 patients, who underwent either high tibial osteotomy (HTO) or unicompartmental knee arthroplasty (UKA), was performed. The preoperative OA grade was reported based on the Ahlbäck and the Kellgren–Lawrence (KL). The hip–knee–ankle angle (HKA), the medial proximal tibial angle (MPTA), the mechanical lateral distal femoral angle (mLDFA) and the joint line convergence angle (JLCA) were recorded. The primary outcome was the relationship between the JLCA values and the OA grade. The secondary outcomes were comparing the JLCA and other alignment parameter values between HTO and UKA groups.ResultsA total of 501 (59.3% females n = 297) cases were included, comprising 293 cases of HTO and 208 cases of UKA. Patients had a mean age of 57.63 ± 8.97 years, a mean BMI of 28.37 ± 7.39 kg/m2. Patients with Ahlbäck grade 2 represented 49.3% of all patients (n = 247) and patients with KL grade 3 represented 54.7% of all patients (n = 274). A high JLCA was observed in both groups. The reported mean JLCA in the UKA group was 3.69 ± 2.1°, and in the HTO group was 2.93 ± 1.82. There was a significant association between the increase in the JLCA and the progression of OA based on both the Ahlbäck and KL grades (both p values < 0.001). The mean JLCA in patients with Ahlbäck grades 1 and 4 was 1.48 ± 1.32°, and 7 ± 0.93°, respectively. The mean JLCA in patients with KL grades 1 and 4 was 1.77 ± 1.42°, and 4.89 ± 1.73°, respectively. The mean recorded preoperative HKA angle in the UKA group was 175.06 ± 3.08°, and in the HTO group was 173.26 ± 3.02°, whereas the mean MPTA was 88.63 ± 1.72° for the UKA group and 89.31 ± 2.29° for the HTO group.ConclusionThe JLCA progressively increases with osteoarthritis progression in patients with unicompartmental varus knee osteoarthritis. The JLCA can potentially be used as a grading parameter for osteoarthritis progression akin to Ahlbäck and Kellgren–Lawrence grading systems.
Long‐lasting decreased pain threshold negatively affects functional recovery after arthroscopic rotator cuff repair
Authors: Ueki Hiroko , Yoshimura Hideya 
Published: October 2023

AbstractPurposeThe relationship between sensitization and postoperative function in patients undergoing arthroscopic rotator cuff repair (ARCR). The purpose of this study was to evaluate the effect of pre‐and postoperative reductions in the pressure pain threshold (PPT) on postoperative clinical outcomes in patients with ARCR and investigate changes in PPT and clinical outcomes resulting from postoperative administration of weak opioids activating the central inhibitory system.MethodsThis retrospective study included patients who underwent primary ARCR, categorized into Group A (excellent/good Constant scores) and B (fair/poor Constant scores). In a complementary study, patients were randomized to the Control or Tramadol groups. Both studies evaluated the PPT, visual analog scale, active range of motion (ROM), Constant score, and retear rates pre‐and postoperatively.ResultsIn the primary study with 158 patients, those with poor clinical outcomes exhibited significantly lower PPT at the affected shoulder preoperatively at 3 months postoperatively compared to those with good outcomes. The PPT of the affected side was lower than that of the uninvolved side not only at 1 and 3 months but also preoperatively and at 6 months in the poor outcome group. In the secondary study involving 96 patients, weak opioid administration was associated with increased PPT for 3 months, improved ROM at 3 months postoperatively, and reduced postoperative pain 1 year postoperatively.ConclusionPatients experiencing poor postoperative clinical outcomes exhibited prolonged lowered PPT. Lowered PPT due to sensitization may adversely affect functional recovery and pain perception. Elevating PPT using weak opioids improved clinical outcomes during the acute perioperative period after ARCR.Level of evidenceIII.
Full-Bayes GNSS-A solutions for precise seafloor positioning with single uniform sound speed gradient layer assumption
Authors: Watanabe Shun-ichi , Ishikawa Tadashi , Nakamura Yuto , Yokota Yusuke 
Published: October 2023

AbstractA systematic analysis methodology for precise seafloor positioning using the GNSS-A has been constructed and implemented in the open-source software GARPOS. It introduces a linearized perturbation field model for extraction of the 4-dimensional sound speed variation, and solves the perturbation parameters simultaneously with the seafloor position based on the empirical Bayes approach. Although it can provide the solutions stably and almost analytically, it has less expandability when imposing additional nonlinear constraint parameters in the observation equation. Even though such parameters can be optimized by applying some information criteria, information on the details of the joint posterior probability would be lost and only the conditional posterior can be estimated. To overcome the above limitations, we implemented full-Bayes estimation using the Markov-Chain Monte Carlo algorithm. This approach can not only help evaluate the dependency of the existing constraint parameters on the seafloor position, but also let us discuss the effects of the additionally imposed constraints. We imposed a constraint under the assumption that a temporally-variable gradient layer steadily lies at a certain depth in the observation scale (typically < 10 km × 10 km, < 1 day). This models the cases with temperature gradients due to a large-scale structure such as the Kuroshio current or internal waves with long-wavelength. The constraint narrows the posterior of the horizontal position and provides a better solution for many datasets, especially in the Nankai Trough region. For the other datasets, the constraint emphasized bias errors, which can also provide information on the possibility of instrumental and modelling errors.
Adipose tissue depot specific expression and regulation of fibrosis-related genes and proteins in experimental obesity
Authors: Eisinger Kristina , Girke Philipp , Buechler Christa , Krautbauer Sabrina 
Published: October 2023

AbstractTransforming growth factor beta (Tgfb) is a well-studied pro-fibrotic cytokine, which upregulates cellular communication network factor 2 (Ccn2), collagen, and actin alpha 2, smooth muscle (Acta2) expression. Obesity induces adipose tissue fibrosis, which contributes to metabolic diseases. This work aimed to analyze the expression of Tgfb, Ccn2, collagen1a1 (Col1a1), Acta2 and BMP and activin membrane-bound inhibitor (Bambi), which is a negative regulator of Tgfb signaling, in different adipose tissue depots of mice fed a standard chow, mice fed a high fat diet (HFD) and ob/ob mice. Principally, these genes were low expressed in brown adipose tissues and this difference was less evident for the ob/ob mice. Ccn2 and Bambi protein as well as mRNA expression, and collagen1a1 mRNA were not induced in the adipose tissues upon HFD feeding whereas Tgfb and Acta2 mRNA increased in the white fat depots. Immunoblot analysis showed that Acta2 protein was higher in subcutaneous and perirenal fat of these mice. In the ob/ob mice, Ccn2 mRNA and Ccn2 protein were upregulated in the fat depots. Here, Tgfb, Acta2 and Col1a1 mRNA levels and serum Tgfb protein were increased. Acta2 protein was, however, not higher in subcutaneous and perirenal fat of these mice. Col6a1 mRNA was shown before to be higher in obese fat tissues. Current analysis proved the Col6a1 protein was induced in subcutaneous fat of HFD fed mice. Notably, Col6a1 was reduced in perirenal fat of ob/ob mice in comparison to the respective controls. 3T3-L1 cells express Ccn2 and Bambi protein, whose levels were not changed by fatty acids, leptin, lipopolysaccharide, tumor necrosis factor and interleukin-6. All of these factors led to higher Tgfb in 3T3-L1 adipocyte media but did not increase its mRNA levels. Free fatty acids induced necrosis whereas apoptosis did not occur in any of the in vitro incubations excluding cell death as a main reason for higher Tgfb in cell media. In summary, Tgfb mRNA is consistently induced in white fat tissues in obesity but this is not paralleled by a clear increase of its target genes. Moreover, discrepancies between mRNA and protein expression of Acta2 were observed. Adipocytes seemingly do not contribute to higher Tgfb mRNA levels in obesity. These cells release more Tgfb protein when challenged with obesity-related metabolites connecting metabolic dysfunction and fibrosis.
