Published: January 2024

AbstractOne of the primary drivers behind adolescents engaging in risk-taking behaviors is the pursuit of status. This study examines how activism and radicalism mediate the relation between the search for status and risk-taking behaviors, moderated by sex. A total of 482 participants, with an average age of 17.97 (SD = 1.83), reported their levels of status-seeking, activism, radicalism, and engagement in risk-taking behaviors. The study revealed an indirect effect of seeking status on risk-taking behaviors through the mechanisms of activism and radicalism. Furthermore, sex moderated the relation between status, activism and radicalism, and risk-taking behaviors. In both girls and boys, activism correlated with reduced engagement in risk-taking, while radicalism correlated with increased engagement. In terms of sex differences, both activism and radicalism showed a more pronounced effect in boys than in girls. These findings highlight the role of political mobilization on the relation between the pursuit of status and engagement in risk-taking.
A simple methodology for identifying speech act tendencies
Authors: Dixon Tülay , Dixon Daniel H. 
Published: January 2024

Abstract
Speech act studies often compare two or more groups of speakers by analyzing how often each group uses a given
strategy to realize a speech act. Since the goal of such studies is to compare groups, they often do not discuss the variation
that exists within the groups and, by extension, what can be considered a speech act tendency for a given group. To illustrate
within-group variation and how such variation can be interpreted to identify the speech act tendencies of a group, this study used
e-mail refusals of requests written by 50 native speakers of English as a case study. Data were collected using a discourse
completion task and analyzed for participants’ strategies to refuse a request. Descriptive statistics show a considerable amount
of variation in this rather homogenous group of English speakers but also allow for the identification of both commonly and rarely
used refusal strategies. These findings highlight the importance of considering the commonly used strategies and the rarely used
strategies when attempting to empirically identify speech act tendencies for teaching and assessment purposes. Implications of the
results for future research, teaching, and assessment practices are discussed.
Sequence organization in L2 interactions
Authors: Garre-León Víctor 
Published: January 2024

Abstract
Employing conversation analysis (CA) to analyze a first encounter between a second language (L2) learner and a
native speaker (NS) of Spanish, this study demonstrates how interactants’ differences in deploying sequence expansion and
recipient uptake impact the interaction. Focusing on sequence organization during storytelling episodes, I argue that both
interactants, teller and recipient, act as co-authors of the telling episode by conveying stancetaking differently, to display
(mis)alignment and/or (dis)affiliation with the telling. The focal data are derived from one videotaped, semi-structured
conversation of an L2-NS dyad. I identify ten focal episodes of sequences representing some form of post-expansions, recipient
uptake, and stancetaking. The study reveals that these two speakers used post-expansions differently: the Spanish NS used them to
accept a second-pair part; the Spanish learner employed them to close a second-pair part and transition toward a new topic, such
as when encountering less-preferred recipient uptake. Gestures and gaze (e.g., looking away from the interlocutor) accentuated
closing a dispreferred second-pair part. Given the importance of recipient uptake in talk-in-interaction, the article offers
implications for research and pedagogy regarding training L2 learners to produce appropriate sequences beyond minimal
post-expansions in talk.

Compositionally while amorphous films exhibited In2Se3 chemical structure, crystalline ones preferred InSe phase. Associated with this type of crystallinity, direct and indirect energy band gap values of 2.32 eV and 3.12 eV are determined. The crystalline films showed lower dielectric constant value accompanied with higher optical conductivity and higher terahertz cutoff frequency in the infrared range of light. In addition the dielectric dispersion spectra were treated using Drude–Lorentz model to read the optical conductivity parameters for the PLW assisted crystalline InSe terahertz resonators. The treatment showed that the crystallinity of the films resulted in improved free carrier density, longer relaxation times at femtosecond level, larger plasmon frequencies and higher drift mobility values. These features together with the response of terahertz cutoff frequency to IR excitations make crystalline InSe thin films promising for optoelectronic and terahertz technology applications.
Development of Schottky barrier field-effect transistors (SB-MOSFET) with ultra-low thermal budget
Authors: Molina-Reyes Joel , Jimenez Arely-Vazquez , Juarez Adriana Mercedes Cuellar 
Published: January 2024

Abstract
This work presents the development of SB-MOSFET transistors incorporating thin HfO2 as a thin gate dielectric deposited by thermal atomic layer deposition (ALD) at low temperature. Aluminum thin films were used as the source/drain (S/D) and gate (G) electrodes, using e-beam evaporation at high-vacuum conditions. Even though low subthreshold slope (SS) values of 111 mV/dec and threshold voltage (Vth) of 0.58 V were obtained using a low thermal budget of 150 °C for transistor fabrication, scanning electron microscopy (SEM) analysis highlights the importance of proper mask alignment in order to enhance electrical performance and thus, reproducibility of the electrical characteristics of this device. This device can be fully integrated into silicon after standard Complementary Metal-Oxide-Semiconductor (CMOS)-compatible processing, so that it could be easily adopted into Front-End-Of-Line or even in Back-End-Of-Line stages of an integrated circuit, where low thermal budget is required and where its functionality could be increased by developing additional and fast logic.
Ion temperature dynamics for the edge and scrape-off layer plasma turbulence: role of gyro-viscosity and vorticity
Authors: Bisai N 
Published: January 2024

Abstract
In the presence of magnetic curvature and density/pressure inhomogeneity, the edge and scrape-off layer (SOL) regions of a tokamak plasma are highly turbulent mainly because of the drift/interchange instability mechanisms. The divergence of ion polarization drift contains the ion diamagnetic drift and

drift velocity to define the plasma vorticity and convection of fluid, which can be approximated in several ways using various combinations of these two drifts. Here, in this work, three different approximations are used to represent three different models and are solved numerically. The numerical results indicate that the basic results of turbulence like radial profiles, radial electric field gradients, fluctuation labels, and Reynolds stress are widely different from the three different models. As these models provide different results, therefore, one must be careful to use these approximations for the description of turbulence. This work may be useful in choosing appropriate approximations to include ion temperature gradients for the turbulence studies on tokamaks/stellarators. The role of gyro-viscosity for plasma turbulence has been identified in this work.
Wear Properties of Metal Material in Dredging Equipment

Published: January 2024

Abstract
In dredging engineering, the parts of dredging and conveying system which contact with dredging mixture often suffer from serious wear and short service life. In order to improve the durability of materials, new materials and generation processes are constantly proposed. It is always a difficult work to analyze the wear properties and mechanism of materials.In this paper, dry friction and abrasive wear tests were carried out on Cr15, Cr26, Fedur®40, medium manganese steel and XGG with Q235 carbon steel as the comparison material. The wear mechanism of materials was analyzed by scanning electron microscope (SEM) observation on the wear surface of materials. Under the test conditions, the dry friction wear rates of the five materials were 6.98×10−6 mm3/Nm,5.71×10−6 mm3/Nm,20.2×10−6 mm3/Nm,21.9×10−6 mm3/Nm and 5.39×10−6 mm3/Nm respectively.The wear rates of abrasive wear tests were 58.3×10−6 mm3/Nm,25.2×10−6 mm3/Nm,83.4×10−6 mm3/Nm,30.9×10−6 mm3/Nm and 32.1×10−6 mm3/Nm respectively. The results show that the metal surface is covered with coarse and deep cutting and chipping marks under abrasive wear, while the metal surface only has fine furrowing and a little fatigue spalling under dry friction wear. The wear rate of abrasive wear of five wear-resistant materials is much higher than that of dry friction wear. Cr26 and XGG showed better wear performance than other materials under the two test conditions.

Abstract
The ICARUS-T600 Liquid Argon (LAr) Time Projection Chamber (TPC) is presently taking data
in the Short Baseline Neutrino (SBN) program at Fermilab (U.S.A.) to search for a possible LSND-like
sterile neutrino signal at Δm
2 ≈ 1 eV2 with the Booster Neutrino Beam (BNB). A
light detection system, based on 360 large area Photo-Multiplier Tubes (PMTs), has been realized
for ICARUS-T600 to detect VUV photons produced by the passage of ionizing particles in LAr. This
system is fundamental for the TPC operation, providing an efficient trigger and contributing to
the 3D reconstruction of events. Moreover, since the detector is exposed to a huge flux of cosmic
rays due to its shallow depths installation, the light detection system allows for the time
reconstruction of events, contributing to the identification and to the selection of genuine
neutrino interactions. The correct time reconstruction of events requires the precise knowledge of
the delay of each PMT channel and a good synchronization of recording electronics, this last based
on fast sampling digitizers. To achieve a time resolution better than 1 ns, we perform three
consecutive timing corrections deployed at different stages of the optical data flow. Results
demonstrate the capability of the ICARUS-T600 light detection system to allow a precise
reconstruction of the temporal evolution of each event occurring in the detector and the
association of neutrino events with the bunched structure of BNB.

Published: January 2024

Abstract
We present the development of a gamma ray and neutron detector for possible use in terrestrial and planetary science. The detector is based on a monolithic scintillator coupled to an array of silicon photomultipliers (SiPMs) read out by compact integrated electronics, and it shall allow one to detect gamma-rays and neutrons with energies from 0.025 eV to 1 MeV with energy resolution of < 4% full-width half-maximum (FWHM) at 662 keV (Cs-137). Among the various scintillators studied, we measured the energy resolution of 4.87% FWHM at 662 keV with a monolithic and cylindrical CLLBC and confirmed acceptable sensitivity to thermal neutrons at 3.1 MeV. The results are promising towards our goal to measure the abundance of hydrogen bearing compounds and rock-forming elements for planetary geology research.

Published: January 2024

Abstract
Located 2 km underground in SNOLAB, Sudbury, Canada, SNO+ is
a large scale liquid scintillator experiment that primarily aims to
search for neutrinoless double beta decay. Whilst SNO+ has light and
radioactive calibration sources external to the inner volume, an
internally deployed optical source is necessary for the full
characterization of the detector model. A laser diffuser ball
developed for SNO has previously demonstrated to be an effective
optical calibration device for both SNO and SNO+ water phase. Since
the introduction of liquid scintillator for SNO+, the material
compatibility, cleanliness, and radiopurity requirements of any
materials in contact with the internal medium have
increased. Improving on the original SNO laserball design, a new
laserball calibration device has been developed for the SNO+
scintillator phase with the goal of measuring the optical properties
of the detector and performing routine PMT gain and timing
calibrations. Simulations have been written to model the diffusion
properties to optimise optical and temporal performance for
calibration. Prototype laserballs have been built and characterised,
demonstrating sub-ns timing resolution and a quasi-isotropic light
distribution.

Abstract
The ion beam extracted from a proton ion source contains
H+ ion along with H2
+ and H3
+ molecular ions. In this
work, the ionic fractions in the extracted beam of ECR ion source
were measured using an analyzing magnet. A computerized proton
fraction measurement setup is described in detail with
instrumentation and control for pulsed operation of the ECR ion
source. A timing diagram has been incorporated for trigger
synchronization illustrating the process of pulsing the plasma,
controlling the analyzing magnet parameters and acquiring data about
the magnetic field and beam current. The proton fraction was
measured in two cases, in the first case using SS304 plasma chamber
and in the second case incorporating aluminium (Al) cylinder and
boron nitride (BN) plates inside the plasma chamber. In the first
case, the proton fraction was found to be in the range of ∼60%
and in the second case because of the presence of secondary electron
donors it increased to 93%. In order to understand the enhancement
of H+ fraction in the hydrogen plasma, plasma parameters (ne

Te
and EEDF) and its dependence on microwave power and neutral
gas pressure were investigated.
Beyond the forecast: knowledge gaps to anticipate disasters in armed conflict areas with high forced displacement
Authors: Jaime Catalina , de Perez Erin Coughlan , van Aalst Maarten , Easton-Calabria Evan 
Published: January 2024

AbstractAlthough conflict-affected populations are often exposed to and severely impacted by disasters, little is known about their perceptions and practices concerning early warning and early action (EWEA) or how EWEA strategies can protect communities affected by conflict- and climate-related disasters. This is particularly problematic as, due to the multiple challenges posed by conflict and compound crises in these contexts, early warnings of weather hazards do not often translate in early actions. This comprehensive literature review examined 384 peer reviewed papers produced between 2004 and 2022, focused on the 20 countries most affected by non-international armed conflict and exposed to climate hazards. This paper answers the question: what is the state of knowledge of EWEA for climate hazards in countries affected by armed conflict and high levels of forced displacement?Findings demonstrate that most research focuses on climate science rather than social science across six elements of the EWEA value chain: 1. hazards analysis, 2. understanding vulnerability and exposure, 3. warning communication and dissemination, 4. forecasting availability and monitoring, 5. early action planning, and 6. financing systems. In total, 75.65% of the research studies focused on hazard analysis, forecast availability, and monitoring. There has been a strong increase in academic research on EWEA in conflict-affected countries since 2004. However, we identify that most of this research has been in Ethiopia, Pakistan, and Nigeria which, although severely affected by conflict, also have a higher level of economic development and stability. In contrast, there is little research focused on EWEA in most of the remaining countries. Across all thematic areas, there is a lack of consideration of conflict dynamics in EWEA research. This paper contributes to evidence on the need to recognize people affected by conflict in disaster risk reduction, as called for in the Sendai Framework for Action midterm review, with the aim of enhancing EWEA investments to enable tailored approaches appropriate for conflict-affected states.
The entanglement criteria based on equiangular tight frames
Authors: Shi Xian 
Published: January 2024

Abstract
Finite tight frames play an important role in miscellaneous areas, including quantum information theory. Here we apply a class of tight frames, equiangular tight frames, to address the problem of detecting the entanglement of bipartite states. Here we derive some entanglement criteria based on positive operator-valued measurements built from equiangular tight frames. We also present a class of entanglement witnesses based on the equiangular tight frames. At last, we generalize the entanglement criterion for bipartite systems to multipartite systems.
The optimization and comparison of two high-throughput faecal headspace sampling platforms: the microchamber/thermal extractor and hi-capacity sorptive extraction probes (HiSorb)

Published: January 2024

Abstract
Disease detection and monitoring using volatile organic compounds (VOCs) is becoming increasingly popular. For a variety of (gastrointestinal) diseases the microbiome should be considered. As its output is to large extent volatile, faecal volatilomics carries great potential. One technical limitation is that current faecal headspace analysis requires specialized instrumentation which is costly and typically does not work in harmony with thermal desorption units often utilized in e.g. exhaled breath studies. This lack of harmonization hinders uptake of such analyses by the Volatilomics community. Therefore, this study optimized and compared two recently harmonized faecal headspace sampling platforms: High-capacity Sorptive extraction (HiSorb) probes and the Microchamber thermal extractor (Microchamber). Statistical design of experiment was applied to find optimal sampling conditions by maximizing reproducibility, the number of VOCs detected, and between subject variation. To foster general applicability those factors were defined using semi-targeted as well as untargeted metabolic profiles. HiSorb probes were found to result in a faster sampling procedure, higher number of detected VOCs, and higher stability. The headspace collection using the Microchamber resulted in a lower number of detected VOCs, longer sampling times and decreased stability despite a smaller number of interfering VOCs and no background signals. Based on the observed profiles, recommendations are provided on pre-processing and study design when using either one of both platforms. Both can be used to perform faecal headspace collection, but altogether HiSorb is recommended.

Abstract
This study aims to analyze the polymorphism of the myostatin (MSTN) gene in exon 1 at SNPc.111G>C (rs523392653) and SNPc.267G>A (rs383271508) on various beef cattle in Indonesia. A total of 136 DNA samples were analyzed in this study, consisting of 33 heads of Madura, 31 heads of PO, 36 heads of Bali, 18 heads of Simmental, and 18 heads of Limousin cattle. The DNA sample was collected from the Animal Molecular Genetic Laboratory, Faculty of Animal Science, IPB University. Along 608 bp of DNA sequence was amplified using PCR with forward primer was 5′-CAA GTT GTC TCT CAG ACT GG-3′ and reverse primer was 5′-CTC CTC CTT ACA TAC AAG CC-3′ and annealing temperature was 59°C. The amplified DNA was then digested with HaeIII and AluI restriction enzymes using the RFLP method to determine polymorphism. Genotype frequencies, allele frequencies, PIC, and heterozygosity values were calculated with the PopGen32 program. The HaeIII enzyme produces two genotypes, GG and CG, while the AluI enzyme produces three: GG, AG, and AA. SNPc.111G>C polymorphism was found in Madura and PO cattle, while SNPc.267G>A polymorphism was found in Madura, PO, and Bali cattle. Both Simmental and Limousin cattle were monomorphic.
Germplasm of Indonesia local pig: potential, threat of extinction, and conservation strategy
Authors: Lase J A , Surya  , Costa M A Da 
Published: January 2024

AbstractOne type of livestock that is widely cultivated by some people is pigs, especially local pigs. Pigs are popular animals and are widely cultivated for needs related to socio-culture, traditional ceremonies, religious ceremonies, weddings and other ceremonies by certain community people’s in Indonesia. Indonesia has germplasm of five local pig species from eight types of pig species in the world. The pigs species lives and develops in several main areas, namely in Sumatra, Kalimantan, East Nusa Tenggara, Sulawesi and Papua. Local pig species in Indonesia include Nias pig, Toba pig, Samosir pig, Bali pig, Toraja pig and Papua pig. Currently, local pigs are facing the threat of extinction, due to low productivity so that people tend to keep imported pigs with better productivity. In addition, the threat of epidemics, poaching and the absence of real preservation and conservation measures from the government have also contributed to the decline in the local pig population in Indonesia. Conservation actions that can be taken include: 1) Establish areas for cultivation and development of local pigs in districts/cities; (2) Maintaining the existence and use of public grazing land for local pig farming; and (3) Develop and increase the productivity of local pigs. In local pigs that have been raised by the community, conservation is carried out by selecting within the clump so that purity is maintained and conservation through efforts to improve the management of local pigs.
