An Unusual Observation in Metastatic Neuroendocrine Neoplasm: Diffuse Pattern Hepatic [68Ga]Ga-DOTATATE Uptake Related to Micro-metastatic Disease and Discordance between Dual-Tracer PET-CT Findings and MIB-1 Labelling Index
Authors: Baberwal Parth , Sonavane Sunita N. , Basu Sandip 
Published: January 2025

AbstractNeuroendocrine neoplasms (NENs) are a rare and diverse group of neoplasms that can originate from neuroendocrine cells in any organ. We herein present a patient with Grade II neuroendocrine tumor (NET) of the pancreas with bilobar liver metastasis and a MIB-1 labelling index of 15%, who underwent various systemic and targeted therapies. On follow-up, dual-tracer PET-CT imaging with [68Ga]Ga-DOTATATE PET/CT showed new onset skeletal metastases and diffuse pattern SSTR (somatostatin receptor) expression in the left lobe of the liver (Krenning score 3), contrasted by absent uptake on [18F]FDG. Magnetic resonance imaging of the liver confirmed sub-centimetric left liver lobe lesions, further biopsy of which suggested Grade-III NET exhibiting high Ki-67 (55–60%). Thus, a discordance was observed between Ki-67 and the dual-tracer PET-CT findings, emphasizing the complexity of NEN imaging (with possibility of differentiation even in a relatively high Ki-67) and the importance of using multiple tracers for accurate assessment in guiding evidence-based management strategy.
Investigation of a flat-type piezoelectric motor using in-plane vibrations
Authors: Li Chong , Lu Cunyue 
Published: January 2025

This paper presents a flat-type piezoelectric motor utilizing in-plane vibration modes. Two piezoelectric ceramic plates in combination with a brass metal sheet were used to construct the stator. The superposition of two second order in-plane vibration modes can generate a traveling-wave inside the stator. The greatest advantage of the proposed motor lies in its sheet structure configuration, which significantly reduces the overall size of piezoelectric motors exploiting in-plane vibrations, particularly in terms of thickness. Meanwhile, the stator also demonstrates greater vibration displacements when compared to higher-order operating modes. Through discussing the impact of stator structure parameters on the vibration deflection angle θ, the excitation ways of operating modes were investigated. Subsequently, the finite element method was utilized to explore both the static and dynamic vibration properties of the stator. Simulation results suggest that at a steady state, stator driving points achieve vibrations at the micro-meter level, satisfying actual application requirements. Finally, a prototype motor was fabricated. Driven by two-phase alternating voltage with a frequency of 69.4 kHz, the no-load speed and stall torque of the prototype motor are 52 rpm and 3.2 mN m, respectively.
Multimodality, conventionality and inheritance in dialogic
constructions
Authors: Nikiforidou Kiki 
Published: January 2025

Abstract
The chapter investigates the multimodal correlates of a family of dialogic challenging
constructions in Modern Greek, anchored to the form ela (2nd person singular imperative of the verb
erxome ‘come’). First, prosodic features of these constructions are analyzed in terms of
intonation measurements in a production experiment, then gestural features are tested in terms of conventionality in a
recognition task. Gesture salience (defined independently of linguistic input) and the
functional space of gestures are discussed as factors that may explain successful and
unsuccessful results in matching gestures and constructions. Preliminary results suggest that while prosodic features
can be integrated in constructional (grammatical) descriptions and into inheritance relations, the gestural correlates
cannot as straightforwardly. Recognizing gesture constructions, optionally coindexed with grammatical
ones, may be one way of resolving the issue.
A multimodal approach to coordination in
spontaneous conversation
Authors: Lelandais Manon 
Published: January 2025

Abstract
This chapter proposes a constructional framework that includes the verbal, vocal, and gestural
modalities to describe coordination in conversation. I suggest a definition for coordination that is not
modality-specific, and provide a detailed analysis of two coordinate structures from a corpus of spontaneous speech in
British English that illustrates this definition. To assess its implications, a series of exploratory analyses
investigating a relationship between discourse sequence type and coordination was carried out. This study is the first
step into a new model for coordination that contributes to the development of a cognitive-linguistic approach to
multimodal and interactional features of language use.
An
evidential function of raised eyebrows in interaction
Authors: Debras Camille 
Published: January 2025

Abstract
In the course of interaction, raised eyebrows is a facial display that can express a wide range of
meanings, e.g. surprise, recognition, salience, or the anticipation of a response. I argue that these meanings are
united by a common evidential feature: they mark a relation between the speaker and addressee’s respective knowledge
or attitudes. More specifically, this intersubjective core function is to express a differential in expectations. In
order to identify the form’s main functions and their multimodal contextual profiles (clusters of features), I combine
quantitative statistical methods (multiple correspondence analysis), based on the fine-grained annotation of the
corpus data (220 occurrences), with the qualitative analysis of excerpts. Sequential position is a key feature: in
turn-initial position raised eyebrows mark a response, in turn-medial position they mark salience, and in turn-final
position, other-orientation. In turn-initial and turn-final position raised eyebrows are multifunctional: they
contribute to regulating turn-taking while displaying an attitude towards the previous or upcoming turn. As a visual
form with a stable core meaning, raised eyebrows qualify as a recurrent gesture. Based on the characteristics of
multifunctionality, intersubjectivity, and functional specialization depending on sequential position, raised eyebrows
could also qualify as a visual pragmatic marker.
Contrastive negation constructions in Israeli
Hebrew
Authors: Inbar Anna 
Published: January 2025

Abstract
This study explores the functions of Hebrew Contrastive Negation constructions (CNs), which are
usually considered grammatical patterns that combine the rejection of an accessible background assumption or an
accessible claim in the discourse via its substitution, with the two being construed as alternatives. The study
elaborates on discourse contexts that require the use of such constructions and shows that the pragmatics of CN
motivates not only the existence of the construction, but also the choice of the particular gestural patterns
coordinated with it. In line with recent developments of multimodal accounts of constructions (e.g., Lanwer, 2017; Schoonjans, 2017;
Steen & Turner, 2013; Zima
& Bergs, 2017), I propose that co-speech gestures should be viewed as an integral part of CNs in
Hebrew.

negativas
Authors: Bonilla-Conejo Marina , Cembrero Bonet Elsa , Leguisamon Tolentino Rocio , Sims Ethan , Zahler Sara 
Published: January 2025

Resumen
En muchas variedades de español, más puede ser antepuesto o pospuesto relativo a las
palabras negativas nada, nadie, nunca o ningún(o/a/os/as). Sin embargo, la frecuencia de
anteposición fluctúa enormemente entre las diferentes variedades del español. En el presente estudio se expanden investigaciones
previas de estas construcciones, analizando dos variedades adicionales del español, Panamá y Puerto Rico, y considerando el efecto
de tres variables sintácticas no consideradas anteriormente, usando una muestra más amplia de datos. Se codificaron 676 ejemplos
de estas construcciones de blogs de Panamá y 1237 ejemplos de blogs de Puerto Rico del Corpus del Español, y se
consideró el efecto de ocho factores sintácticos y semánticos en esta alternancia. Los resultados indican que los factores que
gobiernan esta variación difieren entre los dos países y que estas diferencias reflejan en parte distintas etapas en el cambio de
más pospuesto a más antepuesto.
The Amuric language family
Authors: Gruzdeva Ekaterina , Janhunen Juha 
Published: January 2025

Abstract
This paper deals with the areal and typological position of the Amuric language family, often
classified as an isolate, but actually comprising two distinct dialectal complexes known as Nivkh and Nighvng. The
Amuric varieties are spoken in the Amur-Sakhalin region of the Russian Far East and exhibit several
cross-linguistically rare features. While these features could be assumed to be connected with the position of Amuric
as one of the residual families of the North Pacific Coast, also known as
Palaeo-Asiatic, some of them are actually based on recent innovations and do not represent the
original typology of the Amuric languages. Altogether, the Amuric languages incorporate several chronological layers
connected with the historical movements and areal contacts of their speakers.
An Austronesian-type voice system in an Amazonian isolate?
Authors: Haude Katharina 
Published: January 2025

Abstract
The paper discusses some typologically rare structural similarities between Movima, a South
American isolate, and the Austronesian language Tagalog. Both languages have a symmetrical voice system, and in both
languages verbs and nouns are to some degree syntactically equivalent. For Tagalog, it has been argued that the system
is due to a basically equational sentence pattern with a nominal predicate (the nominalist
hypothesis), and this explanation is also plausible for Movima. In contrast to some accounts of Austronesian
languages, however, there is no evidence of a nominalizing origin of the Movima voice markers. Thus, the discovery
that a phenomenon so far considered unique to one language family also occurs in a linguistic isolate is evidence that
rare phenomena can arise independently of an areal or genealogical relationship. At the same time, typological
parallels between an isolate and a large well-studied family are an interesting source of diachronic hypotheses
regarding an isolate language that lacks historical documentation.
Baroque accretions and isolation
Authors: Terrill Angela 
Published: January 2025

Abstract
This paper presents a case study comparing two Papuan languages of Island Melanesia, Lavukaleve and
Touo, with their Oceanic neighbours, exploring differing outcomes of language contact in micro-contact situations.
Social/geographic isolation has been thought to preserve or enable structural complexity, measured using a complexity
index. It is shown that each of the Papuan members of the contact situations to be described is structurally more
complex than its Oceanic neighbours, but of these, the structurally more complex language is the
socially/geographically more isolated. Among these languages, while there is a relationship between isolation and
complexity, there is a less strong relationship between being isolates and being complex. Thus, in this case at least,
isolates are not necessarily more complex through being isolates.
One language or two?
Authors: Schapper Antoinette 
Published: January 2025

Abstract
This chapter draws attention to the arbitrariness of isolate classifications for many Papuan
languages. So little is known about the history of the vast majority of Papuan languages that most classifications in
the literature are founded neither on significant documentation nor intensive historical-comparative study. The
chapter illustrates how arbitrary the boundaries are in defining isolates versus small language families of Papuan
languages. To highlight this issue, I juxtapose case studies of Yawa-Saweru and Maybrat-Karon. Saweru and Karon are
both referred to as divergent varieties, yet the former is classified as an independent language and
the latter as a dialect. Based on existing literature, it is shown that there is no principled reason to give
different classifications to Yawa-Saweru and Maybrat-Karon.

A vision-inertial interaction-based autonomous UAV positioning algorithm
Authors: Liu Cheng , Song Kecheng , Wang Wantao , Zhang Weihua , Yang Yangkun , Sun Jinyi , Wang Lin 
Published: January 2025

Abstract
In wartime scenarios where global navigation satellite system (GNSS) may be compromised, the cumulative errors associated with inertial navigation systems (INSs) can lead to significant positional deviations during long-distance navigation of drones. To address this issue, this study proposes an innovative vision-inertial interactive autonomous positioning algorithm that integrates visual positioning with inertial measurement unit-based methods, aiming to achieve enhanced system robustness and optimal positioning accuracy. The algorithm first implements an adaptive tile map level selection mechanism based on prior positional information from INS and onboard barometric pressure data, thereby mitigating the impact of inconsistent image scales. Subsequently, the proposed feature point extraction algorithm (Super Point V) effectively filters out invalid and interfering feature points from aerial images and tile maps. Finally, a novel matching mechanism for map expansion based on direction weights is employed to facilitate image matching and positioning, ensuring real-time accuracy and precision. Experimental results across various terrain conditions demonstrate that this approach not only enables accurate real-time computation of latitude and longitude but also effectively corrects the accumulated positioning errors of INS, achieving an average positioning accuracy error of only 4.94 m, comparable to that of conventional civilian GNSS, while maintaining excellent robustness.
Primordial black holes in SB SUSY Gauss-Bonnet inflation
Authors: Ashrafzadeh A. , Solbi M. , Heydari S. , Karami K. 
Published: January 2025

Abstract
Here, we explore the formation of primordial black holes (PBHs) within a scalar field inflationary model coupled to the Gauss-Bonnet (GB) term, incorporating the low-scale spontaneously broken supersymmetric (SB SUSY) potential.
The coupling function amplifies the curvature perturbations, consequently leading to the formation of PBHs and detectable secondary gravitational waves (GWs).
Through the adjustment of the model parameters, the inflaton can be decelerated during an ultra-slow-roll (USR) phase, thereby augmenting curvature perturbations. Beside the observational constraints, the swampland criteria are investigated.
Our computations forecast the formation of PBHs with masses around 𝒪(10)M
⊙, aligning with the observational data of LIGO-Virgo, and PBHs with masses 𝒪(10-6)M
⊙ as potential explanation for the ultrashort-timescale microlensing events recorded in the OGLE data.
Additionally, our proposed mechanism can generate PBHs with masses around 𝒪(10-13)M
⊙, constituting roughly 99% of the dark matter.
The density parameters of the produced GWs (ΩGW
0) intersect with the sensitivity curves of GW detectors. Two cases of our model fall within the nano-Hz frequency regime. One of them satisfies the power-law scaling as ΩGW(f) ∼ f
5-γ, with the γ = 3.51, which is consistent with the data of NANOGrav 15-year.
Catalog-based pseudo-Cℓ
s
Authors: Wolz Kevin , Alonso David , Nicola Andrina 
Published: January 2025

Abstract
We present a formalism to extract the angular power spectrum of fields sampled at a finite
number of points with arbitrary positions — a common situation for several catalog-based
astrophysical probes — through a simple extension of the standard pseudo-Cℓ
algorithm. A
key complication in this case is the need to handle the shot noise component of the associated
discrete angular mask which, for sparse catalogs, can lead to strong coupling between very
different angular scales. We show that this problem can be solved easily by estimating this
contribution analytically and subtracting it. The resulting estimator is immune to small-scale
pixelization effects and aliasing, and, most notably, unbiased against the contribution from
measurement noise uncorrelated between different sources. We demonstrate the validity of the
method in the context of cosmic shear datasets, and showcase its usage in the case of other
spin-0 and spin-1 astrophysical fields of interest. We incorporate the method in the public
<monospace>NaMaster</monospace> code.
Impact of parameters in the toroidal blazar jet magnetic field model on axion-like particle constraints
Authors: Gao Lin-Qing , Bi Xiao-Jun , Li Jun , Yin Peng-Fei 
Published: January 2025

Abstract
The interaction between axion-like particles (ALPs) and photons induces ALP-photon oscillations in astrophysical magnetic fields, leading to spectral distortions in the γ-ray spectrum of blazars. The primary uncertainty of this phenomenon may originate from the magnetic field within the jet of the blazar. Many studies focus on a simple jet magnetic field model with a toroidal component exerting a predominant influence on regions far from the central region. While many investigations have explored the effects of ALP-photon oscillations using typical parameter values in this model, it is important to recognize that these parameters can be constrained by multi-wavelength observations. In this study, we utilize the high energy γ-ray spectrum of Mrk 421 obtained from MAGIC and Fermi-LAT observations. By employing multi-wavelength fitting with a one-zone synchrotron self-Compton model, we derive the parameters characterizing the simple toroidal balazar jet magnetic field model, and investigate their impacts on the ALP constraints.
A flexible parameterization to test early physics solutions to the Hubble tension with future CMB data
Authors: Kou Raphaël , Lewis Antony 
Published: January 2025

Abstract
One approach to reconciling local measurements of a high expansion rate with observations of acoustic oscillations in the CMB and galaxy clustering (the “Hubble tension”) is to introduce additional contributions to the ΛCDM model that are relevant before recombination. While numerous possibilities exist, none are currently well-motivated or preferred by data. However, future CMB experiments, which will measure acoustic peaks to much smaller scales and resolve polarization signals with higher signal-to-noise ratio over large sky areas, should detect almost any such modification at high significance.

We propose a method to capture most relevant possible deviations from ΛCDM due to additional non-interacting components, while remaining sufficiently constraining to enable detection across various scenarios. The phenomenological model uses a fluid model with four parameters governing additional density contributions that peak at different redshifts, and two sound speed parameters. We forecast possible constraints with Simons Observatory, explore parameter degeneracies that arise in ΛCDM, and demonstrate that this method could detect a range of specific models. Which of the new parameters gets excited can give hints about the nature of any new physics, while the generality of the model allows for testing with future data in a way that should not be plagued by a posteriori choices and would reduce publication bias.

When testing our model with Planck data, we find good consistency with the ΛCDM model, but the data also allows for a large Hubble parameter, especially if the sound speed of an additional component is not too different from that of radiation. The analysis with Planck data reveals significant volume effects, requiring careful interpretation of results. We demonstrate that Simons Observatory data will mitigate these volume effects, so that any indicated solution to the Hubble tension using our model cannot be mimicked by volume effects alone, given the significance of the tension.
Horndeski speed tests with scalar-photon couplings
Authors: Babichev Eugeny , Charmousis Christos , Muntz Benjamin , Padilla Antonio , Saltas Ippocratis D. 
Published: January 2025

Abstract
We revisit multi-messenger constraints from neutron star mergers on the speed of
propagation of gravitational and electromagnetic waves in Horndeski and beyond Horndeski
theories. By considering non-trivial couplings between the dark energy field and the
electromagnetic sector, the electromagnetic wave can propagate through the cosmological background
at non-unit speed, altering the phenomenological constraints on its gravitational counterpart. In
particular, we show that recent models derived from a Kaluza-Klein compactification of higher
dimensional Horndeski models fall into a broader class of theories disformally related to those
whose gravitational waves propagate with unit speed. This disformal equivalence can, however, be
broken by the gravitational couplings to other sectors with interesting phenomenological
consequences. We also consider higher order couplings between the scalar and the photon with
second order field equations, and show that they are not compatible with constraints coming from
multi-messenger speed tests and the decay of the gravitational wave.
Hybrid Image Encryption Scheme Based on a Hyperchaotic Map with Spherical Attractors
Authors: Han Zhitang , Cao Yinghong , Banerjee Santo , Mou Jun 
Published: January 2025

Abstract
Existing chaotic encryption schemes primarily focus on single types of images, making the design of hybrid image encryption schemes more suitable for practical applications. In this paper, a hyperchaotic map with a spherical attractor is proposed, which is constructed using spherical coordinates. Dynamical analyses reveal that the hyperchaotic map exhibits global hyperchaos and high complexity, making it capable of generating more complex chaotic sequences suitable for image encryption. A hybrid encryption scheme based on a hyperchaotic map is proposed for 2D images, 3D models, and 3D point clouds. Firstly, the pixels of 2D image and the coordinate data of 3D image are fused into a plaintext cube, which is combined with Hash-512 to obtain the initial value of the hyperchaotic map. Chaotic sequences are utilized for cube space internal confusion and dynamic cross-diffusion. The encrypted images demonstrate high information entropy, and the test results show that the encryption scheme effectively protects the images. The proposed hybrid image encryption scheme provides an efficient solution for securing various types of images.
