Abstract
Biliary drainage is then one of the necessary procedures to help patients suffering from icterus to reduce serum bilirubin levels and relieve symptoms. The aim of this study was identifying risk factors for survival in patients with cholangiocarcinoma (CCA) treated with percutaneous transhepatic biliary drainage (PTBD) and to develop a simple scoring system predicting survival from PTBD insertion. This single-centre retrospective study included 175 consecutive patients undergoing PTBD for extrahepatic CCA (perihilar and distal). Prognostic factors affecting survival of patients with CCA treated with PTBD were analysed. A multivariate analysis showed that mass forming tumor with mass larger than 5 cm and presence of metastasis at the time of PTBD served as a negative prognostic factor (p = 0.002), better survival was associated with lower preprocedural bilirubin and lower CRP (p = 0.003). Multivariate analysis identified two significant risk factors for 3-month mortality: mass-forming tumors and bilirubin levels exceeding 185 µmol/L. A simple scoring system was developed to predict 3-month mortality after PTBD in patients with advanced CCA, demonstrating 86.3% negative predictive value and 43.2% positive predictive value.
A new mechanism of arterial calcification in diabetes: interaction between H3K18 lactylation and CHI3L1
Authors: Zhu Yi , Chen Jingchen , Zhang Jiali , Wang Fangfang , Liu Ruiping 
Published: January 2025

Metabolic changes are an important characteristic of vascular complications in diabetes. The accumulation of lactate in the microenvironment can promote VSMC calcification in diabetes, although the specific mechanism remains to be fully elucidated. In this study, we explored the characteristics of lactylation in diabetic arterial calcification and the underlying molecular mechanism. We found that in high-glucose calcified VSMC, the overall lactylation level was significantly increased. Mass spectrometry analysis revealed significant upregulation of H3 histone lactylation. After site-specific point-mutation at K18 to simulate the delactylation modification, VSMC calcification was significantly reduced. Through a combination of H3K18la ChIP-seq, RNA-seq, H3K18la ChIP-qPCR and point-mutation experiments, we confirmed that H3K18la can upregulate CHI3L1. CHI3L1 knockout significantly alleviated VSMC osteogenic phenotype transformation and mouse arterial calcification. RNA-seq analysis of the downstream molecular signaling showed that CHI3L1 activates the IL-13-IL-13Ra2-JAK1-STAT3 pathway. Targeted inhibition of IL-13Ra2 reduced VSMC calcification. We conclude that in a diabetic calcification environment, the H3 histone K18 site undergoes lactylation modification in VSMCs, upregulating CHI3L1, which in turn regulates the IL-13-IL-13Ra2-JAK1-STAT3 signaling pathway, ultimately exacerbating arterial calcification. Our study elucidates the epigenetic mechanism by which lactate promotes arterial calcification in diabetes.
Measuring Talker Age Estimates Through Crowdsourced Listeners' Ratings: A Pilot Study for Voice Research
Authors: Tripp Raquel M. A. , Hunter Eric J. , Johnson Aaron M. 
Published: January 2025

Purpose:
Most auditory–perceptual voice research utilizes the judgments of trained listeners rather than everyday listeners with no previous training in speech pathology. Online crowdsourcing of behavioral data from untrained participants is rapidly increasing in popularity but has yet to be a common procedure for auditory–perceptual studies of the voice. The objective of this pilot study was to assess the functionality of this model for judgments of voice by using an online experiment platform to replicate a lab-based, voice-specific age estimation study.

Method:
Fifty crowdsourced untrained listeners estimated the age of a single talker based on audio samples taken from 20 speeches over a 48-year span. The primary outcome was overall age estimation accuracy.

Results:
The crowdsourced age estimations closely matched those of a previous highly controlled in-person laboratory study using the same auditory samples. Listeners generally overestimated the talker's age when the talker was younger and underestimated his age when he was older. The age at which the estimated age equaled the talker's chronological age was 54 years.

Conclusions:
Online crowdsourcing may be a feasible modality for auditory–perceptual voice ratings with the potential to add low-cost, high-number options to validate and enhance clinical and laboratory-based studies by (a) including a wider diversity of participants and (b) providing the means for rapidly recruiting more participants. Further research investigating crowdsourced ratings of the complex parameters of voice quality using more listeners is needed to continue supporting this methodology as a tool for perceptual voice research.

Published: January 2025

On-chip polarization splitter–rotators (PSRs) are crucial components for coherent optical communication and polarization-division multiplexing systems. Here, we propose and experimentally demonstrate a polarization splitter–rotator based on the principles of adiabatic mode evolution and the stimulated Raman adiabatic passage on the thin-film lithium niobate (TFLN) platform. The experimental results indicate that the fabricated device exhibits an insertion loss of less than 0.5 dB and extinction ratios exceeding 20 dB over a 130-nm band, with the potential to extend up to 250 nm as predicted by simulations. Large fabrication tolerance is also demonstrated with extinction ratios of more than 20 dB in the wavelength range of 1500–1630 nm. The demonstrated PSR could become an indispensable component in the future TFLN photonic integrated circuits.
The functions of “I think” in TED Talks and their Turkish translations
Authors: Çeltek Aytaç 
Published: January 2025

Abstract
This study provides a comprehensive analysis of the pragmatic marker “I think” and its translation into Turkish,
specifically focusing on its use in TED Talks. Using a corpus-based approach, the research investigates the various functions and
Turkish equivalents of “I think”, revealing significant insights into its role as a commenting speech action. Grounded in speech
act theory, particularly expositive illocutionary acts, the study emphasizes the illocutionary pluralism of “I think” in managing
discourse, expressing speaker attitudes, and engaging interlocutors. The findings highlight the high frequency and critical role
of “I think” in spoken English, its function as a commenting speech action in maintaining discourse coherence, and the notable translation choices in Turkish, such as bence ‘in my opinion’ and sanırım ‘I
suppose/I assume’. This study contributes to pragmatics by enhancing our understanding of the illocutionary pluralism of “I think”
vis-à-vis its translation strategies.
Specified compliments in comments to politicians’ Facebook posts
Authors: Shukrun-Nagar Pnina , Livnat Zohar 
Published: January 2025

Abstract
This article discusses “specified compliments” consisting of a positive evaluation of an ability or achievement; a preposition; and an area of expertise or excellence, e.g. “experts in security”. An analysis of 74 examples in comments on politicians’ Facebook posts during 2020–2021 revealed that specified compliments convey a predominantly ironic meaning in order to criticize the complimentee. Three different categories of ironic specified compliments are identified: (1) compliments where the area of expertise is positive and are interpreted as ironical based on their linguistic and extralinguistic context; (2) compliments where the area of expertise is negative and are thus understood as insincere; and (3) compliments in which the area of expertise is apparently positive but less than other areas, and therefore they are paradoxically interpreted as both sincere compliments in a specific area and a condemnation in general.
Cause and comment
Authors: Konvička Martin 
Published: January 2025

Abstract
In this paper, I investigate the functional dimension of non-finite causal constructions, exemplified using the
English because X constructions. The analysis identifies two functions of these constructions: expressing
causality and commenting. Primarily, non-finite causal constructions express cause or reason. Secondarily, however, speakers can
also use these constructions to offer a comment about the expressed cause or reason. These two functions represent two poles on a
functional continuum. While some non-finite causal constructions only express causal meaning and some serve predominantly as
comments, they usually combine both functions.
The Jewish German-American musicologist Fritz A. Kuttner and China
Authors: Peng Bei , Bartosch David 
Published: January 2025

Abstract
We explore the topic of self-translation in migration through the biography of Fritz A. Kuttner, a German Jewish
economist who became a musicologist during the years he spent in his native country just before he managed to escape from the
Nazis. His interest in musicology intensified as an immigrant in Shanghai from 1939 to 1949, where he also studied pre-modern
Chinese musical culture. After his emigration and becoming a US citizen, Kuttner emerged as a pioneer in this new field. We trace
Kuttner’s path as a whole, but focus especially on his Shanghai years. Among other things, these are marked by his study of the
Chinese language, life in the multilingual Jewish refugee community, music as a meeting point between East and West, his growing
understanding of a connection between Chinese language, music and culture as a whole, and his efforts to translate his
understanding of the semiotics of ancient Chinese music into the language and theoretical perspective of Western musicology. In
addition to documenting his experiences and academic self-translation, we argue in favour of a broader concept of self-translation
as being relevant to an intercultural sense of self.

Lattice-mismatched and twisted multi-layered materials for efficient solar cells
Authors: Manousakis Efstratios 
Published: January 2025

Abstract
We argue that alternating-layer structures of lattice mismatched or misaligned (twisted) atomically-thin layers should be expected to be more efficient absorbers of the broad-spectrum of solar radiation than the bulk material of each individual layer. In such mismatched layer-structures the conduction and valence bands of the bulk material, split into multiple minibands separated by minigaps confined to a small-size emerging Brillouin zone due to band-folding. We extended the Shockley–Queisser approach to calculate the photovoltaic efficiency for a band split into minibands of bandwidth ΔE and mini-gaps δG to model the case when such structures are used as solar cells. We find a significant efficiency enhancement due to impact ionization processes, especially in the limit of small but non-zero δG, and a dramatic increase when fully concentrated Sun-light is used.
Spontaneous heat current and ultra-high thermal rectification in asymmetric graphene: a molecular dynamics simulation
Authors: Yousefi Farrokh , Farzadian Omid , Shafiee Mehdi 
Published: January 2025

Abstract
Non-equilibrium molecular dynamics simulations reveal the existence of a spontaneous heat current (SHC) in the absence of a temperature gradient and demonstrate ultra-high thermal rectification in asymmetric trapezoid-shaped graphene. These unique properties have potential applications in power generation and thermal circuits, functioning as thermal diodes. Our findings also show the presence of negative and zero thermal conductivity in this system. The negative thermal conductivity could enable the design of a conductive heat machine that pumps heat from the cold side to the hot side without additional energy consumption, functioning as a ‘full-free refrigerator’. Meanwhile, zero thermal conductivity paves the way for the development of high-efficiency thermoelectric devices. Simulations were performed in two scenarios: with hydrogenated edges and without them. To ensure the reliability of the results, Reactive Empirical Bond Order and Tersoff potentials were employed. Finally, we examined how the SHC and the temperature difference at which the heat current is zero depend on the sample length, system width, and system temperature.
Rotating radial injection pattern for highly sensitive electrical impedance tomography of human lung anomalies
Authors: Bader Oumaima , Essoukri Ben Amara Najoua , Ernst Oliver G , Kanoun Olfa 
Published: January 2025

Abstract

Objective. Electrical impedance tomography (EIT) is a non-invasive technique used for lung imaging. A significant challenge in EIT is reconstructing images of deeper thoracic regions due to the low sensitivity of boundary voltages to internal conductivity variations. The current injection pattern is decisive as it influences the current path, boundary voltages, and their sensitivity to tissue changes. Approach. This study introduces a novel current injection pattern with radially placed electrodes excited in a rotating radial pattern. The effectiveness of the proposed pattern was investigated using a 3D computational model that mimics the human thorax, replicating its geometry and tissue electrical properties. To examine the detection of lung anomalies, models representing both healthy and unhealthy states, including cancer-like anomalies in three different positions, were developed. The new pattern was compared to common patterns—adjacent, skip 1, and opposite—using finite element analysis. The comparison focused on the current density within lung nodules and the sensitivity to changes in anomaly positions. Main results. Results showed that the new pattern achieved the maximum current density within anomalies compared to surrounding tissues, with peak values near the closest electrode pairs to the anomalies. Specifically, current density magnitudes reached

Abstract
Nanomaterials have facilitated the development of innovative technologies in various industries. However, most research has been limited to nanoscale phenomena, and the effects of nanomaterials on microscale crystal growth remain obscure. In this study, we demonstrated a straight 2H–Si microneedle with a longitudinal growth rate of 6.7 × 104 Å·s−1, which could not be explained by conventional crystal growth mechanisms, through AlN nanowires. The AlN nanowires were grown using the hydride vapor-phase epitaxy method, which induced the formation of Al membranes when NH3 supply was ceased. At this time, an elliptical Al membrane was created within 0.166 s, in accordance with the principle of Plateau–Rayleigh instability. The average spacing of the Al membrane was 4 μm, and approximately 10 000 elliptical Al membranes absorbed SiCl almost simultaneously to form a 40 mm 2H–Si microneedle within 100 min of growth time. Therefore, we realized straight 2H–Si microneedles with a growth rate of 6.7 × 104 Å·s−1. Differing from the conventional growth mechanism, this new growth method sheds light on the mechanism by which nanoscale phenomena contribute to the growth of microscale crystals.
Thermal effects on the resistive superconducting transition in step-edge YBCO squid arrays
Authors: de Andrade Marcio C , Ferrante Nicholas , Maialle Marcelo Z , Sundqvist Kyle , Torikachvili Milton S 
Published: January 2025

Abstract
The effect of thermal fluctuations in yttrium barium copper oxide SQUID filters (SQIFs), containing arrays of 258, 2304, and 4080 superconducting quantum interference devices (SQUIDs), were investigated using the electrical resistivity and applied magnetic field up to 9 T. Our study reveals that the SQIFs experience a two-step superconductor transition. The transition at lower temperature is only present in the SQIF samples, not in the control sample without the SQIFs, and it is investigated here in terms of two primary dissipation mechanisms. The first dominates near the transition temperature and has the characteristics of thermally activated phase slippage. At lower temperatures, the dominant characteristics are those of thermally-activated magnetic flux flow. The mechanisms producing such behaviors contribute significantly to dissipation effects, resulting in an additional DC voltage that overlays the Josephson current, regardless of the quantity of SQUIDs in the SQIFs. These dissipation effects can have significant implications for technologies utilizing high-temperature superconductor SQIFs unless the operating temperature is lowered significantly below the superconducting transition temperature.
Cooperative co-evolution deep echo state network for time series prediction
Authors: Chen Jianwei , Lun Shuxian , Li Ming 
Published: January 2025

Abstract
The deep echo state network demonstrates strong predictive performance in time series tasks, but inter-layer weight optimization and reservoir structure design are still challenging tasks. To address this, we propose the cooperative co-evolution deep echo state network (CCEDESN). Firstly, inspired by the hierarchical structure of the brain, we introduce a modular hierarchical design. Each layer of the reservoir contains multiple sub-reservoirs, with central neurons in each sub-reservoir interacting with those in other sub-reservoirs to enhance information processing. Secondly, an advanced cooperative co-evolution algorithm is proposed to simultaneously optimize the layer connection weights and (hyper)parameters of the deep echo state network. We evaluate the CCEDESN model on the Mackey-Glass system, Sunspot data, and Apple stock opening prices. The experimental results show that the CCEDESN model achieves superior prediction accuracy compared to other models.

Authors: Wang H M , Li Y S 
Published: January 2025

Abstract
The main objective of this paper is to address the backward problem in the distributed-order time-space fractional diffusion equation (DTSFDE) with Neumann boundary conditions using final data. We began by employing the Finite Difference Method (FDM) combined with matrix transformation techniques to compute the direct problem of DTSFDE. Subsequently, by using the Tikhonov regularization method, the inverse problem is transformed into a variational problem. With the help of the derived sensitivity and adjoint problems, the conjugate gradient algorithm is employed to find an approximate solution for the initial data. Finally, through numerical examples in one and two dimensions, we demonstrated the effectiveness and stability of this method, further verifying its reliability in practical applications.

Published: January 2025

Abstract
Predicting photovoltaic power generation is important for enhancing the operation and management of photovoltaic power systems, as well as boosting their electricity production efficiency. An ultra-short-term photovoltaic power generation prediction model based on ResNet is proposed to address the current issues of unsatisfactory ground-based cloud image prediction performance and unfavorable marginalization deployment. After analyzing and processing the sky image, the ResNet network is used for feature extraction. Historical photovoltaic power generation data is used as input and fused with the results of feature extraction. Finally, the photovoltaic power generation power is predicted. The result of the experiment showed that the model proposed can effectively extract feature information for predicting ultra-short-term photovoltaic power generation.

Published: January 2025

Abstract
The conventional microgrid adjustable energy storage phased optimization configuration method mainly uses MGCO\SESO (micro-grid cluster operator\shared energy storage operator) capacity sharing game strategy to optimize the third party, which is susceptible to the two-way interaction of energy storage. Therefore, an effective staged optimal configuration method for adjustable energy storage in remote rural microgrids is designed under the multi-time scale of demand response. That is, a phased optimal configuration model for microgrid adjustable energy storage is constructed, and a phased optimal configuration strategy for microgrid adjustable energy storage is generated by considering multiple time scales of demand response, thereby achieving a phased optimal configuration of microgrid adjustable energy storage. The experimental results show that the designed phased optimal configuration method of adjustable energy storage in microgrids has a good configuration effect, and the optimal configuration indicators of various energy storage are good, which has a certain application value.
