Published: August 2024

Abstract
Background and Objectives Metastatic gastric carcinoma makes the current treatment options unsatisfactory. There is HER2 directed therapy like transtuzumab are used in metastatic gastric cancer. This study aimed to determine the tissue HER2/neu status by immunohistochemistry (IHC) and find their relation with clinicopathological parameters for assessing the prognosis.
Study Design, Materials, and Methods In this descriptive study, 30 patients of gastric cancer with metastasis were studied for HER2/neu expression by IHC. The chi-square test was used to determine the association between HER2/neu expression and clinicopathological parameters of patients.
Results and Conclusion The majority of samples (90%) were endoscopic biopsies from patients with a mean age of 61.4 years. Tumors were majorly of intestinal type (67%) with moderately differentiated grade located at the fundus of the stomach. The common site of metastasis was the lymph node (53.33%) followed by lymph node and liver metastasis (13.33%). The overexpression of HER2/neu by IHC was observed in 13.3% of cases. Furthermore, no significant association was observed between HER2/neu and gender, diet, age, tumor site, subtype, and grade. Overall, HER2/neu overexpression can be considered an independent prognostic factor for carcinoma stomach. Therefore, the patients identified with HER2/neu overexpression are targeted for trastuzumab therapy.

Electron Beam Ion Traps (EBITs) serve as efficient tools for producing and studying highly charged ions. In response to the diagnostic requirements of upcoming magnetic confinement fusion devices, a medium-energy atomic spectra research platform based on a compact EBIT is developed. This platform achieves a central magnetic field of up to 1.0 T, with electron beam currents reaching 20 mA and electron energies up to 30 keV, similar to the electron temperature on fusion reactors. The developed atomic spectra platform successfully provided spectral data for elements such as argon, xenon, iron, and tungsten. This platform stands as a valuable asset for advancing research in nuclear fusion, particularly concerning impurity spectroscopic diagnostics.
Hydration structure and dynamics of phosphoric acid and its anions—Ultrafast 2D-IR spectroscopy and ab initio molecular dynamics simulations
Authors: Kundu Achintya , Fingerhut Benjamin P. , Elsaesser Thomas 
Published: August 2024

The hydration shells of phosphate ions and phosphate groups of nucleotides and phospholipid membranes display markedly different structures and hydrogen-bond strengths. Understanding phosphate hydration requires insight into the spatial arrangements of water molecules around phosphates and in thermally activated structure fluctuations on ultrafast time scales. Femtosecond two-dimensional infrared spectroscopy of phosphate vibrations, particularly asymmetric stretching vibrations between 1000 and 1200 cm−1, and ab initio molecular dynamics (AIMD) simulations are combined to map and characterize dynamic local hydration structures and phosphate–water interactions. Phosphoric acid H3PO4 and its anions H2PO4−, HPO42−, and PO43− are studied in aqueous environments of different pH value. The hydration shells of phosphates providing OH donor groups in hydrogen bonds with the first water layer undergo ultrafast structural fluctuations, which induce a pronounced spectral diffusion of vibrational excitations on a sub-300 fs time scale. With a decreasing number of phosphate OH groups, the hydration shell becomes more ordered and rigid. The 2D-IR line shapes observed with hydrated PO43− ions display a pronounced inhomogeneous broadening, reflecting a distribution of hydration geometries without fast equilibration. The AIMD simulations allow for an in-depth characterization of the hydration geometries with different numbers of water molecules in the first hydration layer and different correlation functions of the fluctuating electric field that the water environment exerts on the vibrational phosphate oscillators.

Background Understanding community preferences for vaccination services is crucial for improving coverage and satisfaction. There are three main approaches for COVID-19 vaccination in Indonesia: health facility-based, community-based, and outreach approaches. This study aims to assess how the vaccination approaches impact user satisfaction levels. Methods This study was part of a large household survey involving 12,120 respondents across nine districts in Bali Province. The study population comprised all residents aged ≥12 years who had received at least one dose of COVID-19 vaccination. Samples were selected through three stages of systematic random sampling. Data were collected through interviews using structured questionnaires, which included socio-demographic characteristics, vaccination services, and satisfaction levels. Analysis was performed using Chi Square test and logistic regression, with the entire process incorporating weighting factors. Results A total of 12,120 respondents reported receiving their first dose of COVID-19 vaccination. The satisfaction level among vaccine recipients (partial, complete, and booster doses) was high (84.31%). Satisfaction within each SERVQUAL dimension was highest in tangibles (96.10%), followed by responsiveness (93.25%), empathy (92.48%), assurance (92.35%), and reliability (92.32%). There was no significant difference in the overall SERVQUAL score between the health facility and community-based approaches. However, the latter slightly improved user satisfaction across three dimensions: tangibles (adjusted odds ratio, AOR = 1.52, 95% confidence interval (CI) = 1.21–1.90), reliability (AOR = 1.67, 95%CI = 1.42–1.96), and assurance (AOR = 1.26, 95%CI = 1.07–1.48). Conclusion During the pandemic, both health facility and community-based approaches resulted in a high satisfaction level. It is recommended that the government prioritise and optimise community-based programs and health facility-based delivery in future vaccination initiatives, especially during public health emergencies.
Exploring diachronic variation in discernment politeness in Ancient Egyptian
Authors: Ridealgh Kim , Almansa-Villatoro M. Victoria 
Published: August 2024

Abstract
In this paper, we investigate evidence of diachronic variation in patterns of Discernment Politeness in letters
written in the ancient Egyptian Old Kingdom (c. 2300–2200 bce) and Late Ramesside period
(c. 1099–1069 bce). We present examples of requests, information acts and honorifics used in these
letters, predominantly those letters sent by subordinates to their superiors, to explore how this relationship dynamic is
linguistically indexed. Our evidence shows that throughout the Old and New Kingdoms, communicative acts were regulated by
behavioural norms dependent on power structures rather than individual volition, with Power being the most dominant social
variable. Finally, we argue that Discernment is a key approach for exploring politeness in texts from ancient Egypt, supporting
current research on the topic, and that the approach used here for the ancient Egyptian material has wider applicability for
diachronic linguistic analyses of remote civilisations which are highly hierarchical.
Metaphor clusters in political discourse
Authors: Athanasiadou Angeliki 
Published: August 2024

Abstract
The paper explores the creative combination of metaphors, both complex and mixed. The data for the study are drawn
from political discourse concerning the target concept of crisis. Building on the argument that constructional parameters
facilitate metaphor clustering, the paper also focuses on adjectival constructions. The general claim that constructional
parameters and figurative meaning are interdependent is thus supported. It is shown that as complex and mixed metaphors are
created, they both reveal and emphasize the speakers’ political ideologies.
Engineering and control of the entanglement for four Magnon modes inside two microwave cavities
Authors: Imara Ziyad , El Anouz Khadija , El Allati Abderrahim 
Published: August 2024

Abstract
We present a model for investigating the entanglement features of four magnon modes in four yttrium-iron-garnet spheres dispersed in two microwave cavities (each cavity containing two spheres), which are driven by a squeezed field under actual experimental conditions. Each two-magnon mode inside each cavity is coupled via a beam splitter. We solve the covariance matrix associated with the four magnons, taking into account the relevant physical parameters. To quantify the degree of entanglement, we use the logarithmic negativity measure. Our study focuses on two parts. First, we study the entanglement properties between magnon modes by modifying the system parameters, and comparing the results with those obtained when we use a single magnon in each cavity, i.e. when one of the two magnons is not coupled to the cavity. In the second part, we give a new method for enhancing and controlling entanglement between magnon modes. We analyze the case where one of the two magnons is not coupled to the cavity, which can result a significant entanglement. Indeed, this goal is met in our situation by including an effective magnon–magnon coupling into both cavities. However, at high temperatures, the entanglement is almost completely broken. It can withstand temperatures of up to hundreds of millikelvin when using an experimentally accessible two-mode squeezed source.

Authors: Mao Zhihao , Li Da , Li Er-Ping 
Published: August 2024

Abstract
Metasurfaces have attracted widespread attention in recent years due to their powerful electromagnetic wave manipulation capabilities. This paper proposes and validates a single-polarized, angle-adjustable reflective digital coding metasurface. Each unit cell achieves independent reflection phase control by loading a PIN diode for on-off switching. The unit’s design and coding scheme are carefully optimized to ensure the performance of the proposed reconfigurable metasurface. As a validation, a prototype consisting of 16×16 elements is fabricated and measured, with a control signal provided by a field-programmable gate array controller. Experimental results demonstrate angle control of up to ±60° in the frequency range of 3.4 GHz–3.6 GHz, a peak gain of 24.9 dBi in a single channel, and gain exceeding 10 dBi across a 200 MHz operational bandwidth. Furthermore, the performance is validated in a communication system, yielding positive results. The proposed reflective digital coding metasurface contributes to the advancement of reconfigurable intelligent surfaces and holds promise for widespread adoption in various communication scenarios.

Abstract
Reliable vertical position control will be an essential element of any future tokamak-based fusion power plant in order to reduce disruptions and maximize performance. We investigate methods to improve vertical controllability boundary determination in plasma operational space and demonstrate a data-driven approach based on direct pseudoinversion of operational space data that is rigorously quantitative, applicable in real-time plasma control systems, and physically intuitive to interpret. Applied to historical shot data from entire run campaigns on the MAST-U, KSTAR, and NSTX tokamaks, this approach, implemented in DECAF, improves vertical displacement event identification accuracy to 98.9%–100%. Further, we explore the application of a physics-based vertical stability metric as an early warning forecaster for vertical displacement events. The development of a linear surrogate model for the plasma current density profile, with a coefficient of determination of 0.992 on the training dataset, enables potential employment of this forecaster in real-time. The application of this approach on historical data from the MAST-U MU02 campaign yields a forecaster with 62.6% accuracy, indicating promise for this method when further refined and potentially coupled with other stability metrics.
On the inverse problem of time dependent coefficient in a time fractional diffusion problem by sinc wavelet collocation method
Authors: Bayrak Mine Aylin , Demir Ali 
Published: August 2024

Abstract
The object of this study is to establish the unknown function in a time fractional diffusion problem and the solution as well by utilizing Sinc wavelet collocation method (SWCM) and residual power series method (RPSM) together. SWCM enables us to convert time fractional diffusion problem into a system of fractional ordinary differential and algebraic equations. At this stage, the unknown function and the solution are constructed in the series form by employing RPSM. The novelty of this study is that the combination of SWCM and RPSM is utilized to establish the solution of inverse coefficient problem for the first time. Demonstrative examples are presented to articulate the implementation and importance of the proposed method.
Robust optimal control for a systematic error in the control amplitude of transmon qubits
Authors: Cykiert Max , Ginossar Eran 
Published: August 2024

Abstract
In the era of Noisy Intermediate-Scale Quantum computing as well as in error correcting circuits, physical qubits coherence time and high fidelity gates are essential to the functioning of quantum computers. In this paper, we demonstrate theoretically and experimentally, that pulses designed by optimization can be used to counteract the loss of fidelity due to a control amplitude error of the transmon qubit. We analyze the control landscape obtained by robust optimal control and find it to depend on the error range, namely the solutions can get trapped in the basin of attraction of sub-optimal solutions. Robust controls are found for different error values and are compared to an incoherent loss of fidelity mechanism due to a finite relaxation rate. The controls are tested on the IBMQ’s qubit and found to demonstrate resilience against significant ∼10% errors.
Non-Gaussian two mode squeezed thermal states in continuous variable quantum teleportation
Authors: Kumar Chandan 
Published: August 2024

Abstract
We consider a practical scheme for the implementation of non-Gaussian operation, viz., photon subtraction, photon addition, and photon catalysis, on two-mode squeezed thermal state. The generated states are employed as resources in continuous-variable quantum teleportation. The results show that the three non-Gaussian operations can enhance the teleportation fidelity. Considering the success probability of the non-Gaussian operations, we identify single-photon catalysis and single photon subtraction to be optimal for teleporting input coherent states and squeezed vacuum states, at low and intermediate squeezing levels, respectively.
Shock dynamics model based on the conductor hardening and thermal softening effects for single-turn coil
Authors: Ge Aoming , Pan Ziying , Liu Zhengyang , Yang Haocheng , Lv Yiliang , Peng Tao 
Published: August 2024

Abstract
Single-turn coil (STC) is a destructive pulse magnet aiming at 100–300 T ultra-high magnetic field. In this study, a conductor shock dynamics model based on the hardening and thermal softening effects is proposed for STCs. Using this model, the changes in mechanical parameters of the conductor during discharge are investigated. The results show that the yield strength and bulk modulus of the conductors are significantly strengthened during discharge. Moreover, without considering hardening in the simulations, the deformation velocities and displacements of the conductors are higher than when hardening is considered, causing the magnetic fields obtained from the simulation to be smaller than the actual values. The model is validated by checking the consistency of the magnetic flux density at the central axis of the STCs, and the conductor deformation degrees of the simulation results, and the experimental data.

Systematic moment expansion for electroweak baryogenesis
Authors: Kainulainen Kimmo , Venkatesan Niyati 
Published: August 2024

Abstract
We present a systematic moment expansion for solving the semiclassical Boltzmann equations for electroweak baryogenesis. The expansion is developed in powers of adiabatic coordinate velocity, and it is used for computing the CP-violating seed asymmetry at the front of the phase transition wall, that sources the eventual baryon asymmetry of the universe (BAU). We implement the method in a benchmark model, with a CP-violating mass arising from a dimension-5 operator coupling the fermion to a singlet scalar field. We find that the higher moment calculations yield a BAU that can significantly differ from the commonly used two-moment approximation. We discuss in detail the underlying approximations in the moment method and propose a new truncation scheme for the expansion, that appears to give more numerically robust results than the previous schemes.
The roles of environment and interactions on the evolution of red and blue galaxies in the EAGLE simulation
Authors: Das Apashanka , Pandey Biswajit 
Published: August 2024

Abstract
We study the evolution of the red and blue galaxies from
z=3 to z=0 using the EAGLE simulation. The galaxies in the blue
cloud and the red sequence are separated at each redshift using a
scheme based on Otsu's method. Our analysis shows that the two
populations have small differences in the local density and the
clustering strength until z=2, after which the red galaxies
preferentially occupy the denser regions and exhibit a significantly
stronger clustering than the blue galaxies. The
significant disparities in cold gas mass and specific star
formation rate (sSFR) observed before z=2 suggest that factors
beyond environmental influences may also contribute to the
observed dichotomy. Interacting galaxy pairs at a given
separation exhibit a higher SFR at increasing redshifts, which may
be linked to the rising gas fractions at higher redshift. As
redshift decreases, the SFR decreases across all separations,
suggesting a gradual depletion of the cold gas
reservoir. At pair separations < 50 kpc, an
anomalous increase in the SFR among paired galaxies in isolation
around z ~ 2 suggests that environmental effects begin to
dominate at this redshift, thereby increasing the rate of galaxy
interactions and the occurrence of starburst galaxies. We observe
a substantial decrease in the blue fraction in paired galaxies
starting from z=1 to the present. However, the decrease in the
blue fraction in paired galaxies with their second nearest neighbour
at a distance greater than 500 kpc continues until z=0.5, after
which the blue fraction begins to increase.

Abstract
It is determined that while heat flux differences between hydrogen and deuterium isotope experiments result from natural differences in carbon impurity content at DIII-D, it is not the origin of the low to high confinement mode (L-H) transition isotope effect. More specifically, a two times larger edge radial electric field in hydrogen compared to deuterium is uncovered and believed to play an important role. The origin of this radial electric field difference is determined to have two possible origins: differences in poloidal rotation and turbulent Reynolds stress in the closed field line region, and increased outer strike point temperatures and space potentials on open field lines. Experimental observations from both profile and turbulence diagnostics are supported by nonlinear gyrokinetic simulations using the code CGYRO. Simulations illustrated heat transport isotope effects in the plasma edge and shear layer resulting from differences in impurity content, electron non-adiabaticity, and main ion mass dependent E × B shear stabilization. Turbulence prediction comparisons from flux-matched CGYRO simulations to experimental measurements including electron temperature, density and velocity fluctuations are found to be in good agreement with available data. A dedicated DIII-D experiment in hydrogen was performed to seed more carbon than naturally occurring, to match deuterium experiments, and possibly reduce the L-H power threshold based on gyro-kinetic predictions. To our surprise, while ion temperature gradient (ITG) turbulence was stabilized, nodiscernible change in L-H power threshold were observed in these special hydrogen experiments. In particular, it is noticed that the edge radial electric field and Reynolds stress were observed as nearly unchanging in the presence of ITG stabilization. These experimental data have enabled a more comprehensive picture of the multitude of isotope effects at play in fusion experiments, and the important potential connection between the confined and unconfined plasma regions in regulating L-H transition dynamics.
