The three main crystalline modifications of Ga2O3, namely α-phase, ε-phase, and β-phase were grown on sapphire substrates using the hydride vapour phase epitaxy (HVPE) method. The temperatures of the substrates and the values of the precursor fluxes required to obtain each phase exclusively were determined. It was observed that the metastable ε-phase easily transforms into a stable β-phase during annealing. However, the metastable α-phase undergoes an intermediate amorphous phase during annealing, leading to flaking and collapse. This behavior arises from the excessively large increase in density (~10%) during the transformation from α-phase to β-phase, which results in significant elastic stresses and an increase in the height of the phase transition barrier.

The results of experimental studies on registration of the radiative component of the total heat flux by a thermoelectric detector in a reflected shock wave are presented. An increase in the contribution of radiation to the heat flux with an increase in the intensity of the shock wave is estimated. It is shown that the technique can be used in experiments in shock tubes to isolate the radiative component of the total heat flux, and the thermoelectric detector itself can be successfully used to record such parameters.

Grammatical Metaphor in Political Discourse in the Central Kurdish Language
Authors: Shekhani Hawsar A. , Jaff Daban Q.
Published: August 2023

The goal of this work is to examine political discourse in the Central Kurdish language via the prism of Halliday's grammatical metaphor. Political discourse is a common form of public discourse. In the SFG, Halliday identified the ideational and interpersonal grammatical metaphor. This study pertains to the study of Systemic Functional Grammar in that it studies the linguistic metaphors in the political speeches of Mala Bakhtyar and Abul Latif. The two figures are representing two opposing ideologies and they promote different types of religious and political ideologies.  The authors utilized a mixed-methods strategy using Halliday's grammatical metaphor to assemble the findings. In the paper, the following research objectives are addressed: The most frequent form of nominalized processes and mood grammatical metaphor in the political public speeches in CK, in the political discourse in Central Kurdish are focused. Second, the expression of reality through ideational grammatical metaphor is investigated. And lastly, the convey of interpersonal meaning in interpersonal grammatical metaphor in the speeches by the political figures is examined. Overall, 133 distinct nominalized processes were identified during the speeches. Four of the six distinct nominalized types of processes were used. The total number of nominalized material process selections is 65, (48.8%) of the total, with verbal process types accounting for 58 events, (43.6%) of the total, and mental process types accounting for only 9 selections, (6.7%). Only one behavioral type was used, accounting for 0.75%. There are no other nominalized process types. And 53 instances of mood grammatical metaphor were drawn. In addition, the authors discovered that both political figures strive to represent their political beliefs using nominalized process types, and the interpersonal mood grammatical metaphor conveys interpersonal meaning.

Published: August 2023

Background

Using traditional patient-reported outcomes (PROs), such as paper-based questionnaires, is cumbersome in the era of web-based medical consultation and telemedicine. Electronic PROs may reduce the burden on patients if implemented widely. Considering promising reports of DryEyeRhythm, our in-house mHealth smartphone app for investigating dry eye disease (DED) and the electronic and paper-based Ocular Surface Disease Index (OSDI) should be evaluated and compared to determine their equivalency.

Objective

The purpose of this study is to assess the equivalence between smartphone app–based and paper-based questionnaires for DED.

Methods

This prospective, nonblinded, randomized crossover study enrolled 34 participants between April 2022 and June 2022 at a university hospital in Japan. The participants were allocated randomly into 2 groups in a 1:1 ratio. The paper-app group initially responded to the paper-based Japanese version of the OSDI (J-OSDI), followed by the app-based J-OSDI. The app-paper group responded to similar questionnaires but in reverse order. We performed an equivalence test based on minimal clinically important differences to assess the equivalence of the J-OSDI total scores between the 2 platforms (paper-based vs app-based). A 95% CI of the mean difference between the J-OSDI total scores within the ±7.0 range between the 2 platforms indicated equivalence. The internal consistency and agreement of the app-based J-OSDI were assessed with Cronbach α coefficients and intraclass correlation coefficient values.

Results

A total of 33 participants were included in this study. The total scores for the app- and paper-based J-OSDI indicated satisfactory equivalence per our study definition (mean difference 1.8, 95% CI –1.4 to 5.0). Moreover, the app-based J-OSDI total score demonstrated good internal consistency and agreement (Cronbach α=.958; intraclass correlation=0.919; 95% CI 0.842 to 0.959) and was significantly correlated with its paper-based counterpart (Pearson correlation=0.932, P<.001).

Conclusions

This study demonstrated the equivalence of PROs between the app- and paper-based J-OSDI. Implementing the app-based J-OSDI in various scenarios, including telehealth, may have implications for the early diagnosis of DED and longitudinal monitoring of PROs.

Authors: Jiawei Ding , Yunpeng E
Published: August 2023

With the rapid development and wide application of the Internet, network security has become an important issue in modern society. Network attacks such as network worms, botnets and computer viruses are constantly emerging, bringing serious threats and economic losses to the Internet infrastructure. In this context, Network Intrusion Detection/Prevention System (NIDS/NIPS) plays a key role in protecting the Internet infrastructure. By monitoring network traffic in real time, NIDS/NIPS is able to detect and identify internal and external security intrusions in a timely manner and take appropriate measures for defense. Ensuring the high performance of NIDS/NIPS is an important topic in network security research, because the increase of Internet traffic and the variety of attacks make it face great challenges. In this paper, we will explore the fundamentals and functions of NIDS/NIPS and their key role in protecting the Internet infrastructure. We will also discuss key techniques to improve the performance of NIDS/NIPS and look at future directions in this area. An in-depth understanding and study of the theory and technology of NIDS/NIPS is an important reference for professionals in the field of network security.

Study on Collapse Optimization of Weak Axis Moment Connections
Authors: Pius Maria , V N Mr. Krishnachandran
Published: August 2023

Abstract: 3D Weak axis moment connections are the connections between the beam with the web of an I section. But these connections are weaker as they are connected to the web which are thinner portions of the I section compared to flanges. This can lead to buckling of flanges. A new reduced beam section (RBS) connection, consisting of radius cuts in the beam flanges and circular openings in the beam webs, is proposed to allow for more ductile connections. RBS connections may increase structural deflection and crack width in the steel frame structure under large deformations. Therefore, it is extremely important to consider the bearing capacity and progressive collapse resistance of steel frame structures with RBS connections. Progressive collapse analysis of weak axis moment connections without any improvisation is taken for analysis and their collapse location and collapse resistance studied. To enhance weak joint connection design and to delay collapse time, we introduce reduced beam sections. Curved cell reduced beam sections are modeled and analysis is performed for various thickness of cell and by changing diameter. Thus, an effective size was obtained by combining the results with the conventional and the effective location of weak axis is improved

Published: August 2023

This study conducted a demonstration of the price formation factors of small and medium-sized office buildings accessible to individual investors. The various factors that affect the price determination of real estate are fixed factors that the real estate itself has, and it is subdivided into regional conditions, traffic conditions, access conditions, and building conditions. In addition, the macro environment, regional environment, and trader environment that fluctuate according to the market environment to be focused on in this study were added. The extent to which these various factors affect the formation of the transaction price of small and medium-sized office buildings was analyzed. Let's take a look at the main analysis results of market environmental factors. As factors related to the macroenvironment, interest rates and CPI variables significantly affected the transaction prices of small and medium-sized buildings. In addition, changes in the apartment sales price index and publicly announced land prices had a statistical effect on the formation of the transaction price of small and medium-sized buildings. In addition, the transaction price of small and medium-sized buildings was formed higher in the case of corporate transactions than individual transactions.

A study on Improvement Local Disaster Prevention through Resident Communities: Focusing on Japan's District disaster prevention plan
Authors:   Residential Environment Institute Of Korea, Cho Pil-Kyu
Published: August 2023

This study analyzed the characteristics of regional disaster prevention-related laws and cases through residents' communities in Japan, with the purpose of presenting policy direction for improving disaster preparedness in the event of a disaster in Korea. As a result of the study, the following conclusions were obtained. First, when large-scale disasters such as the Hanshin-Awaji earthquake and the Great East Japan Earthquake occurred in Japan, residents' activities through self-help and mutual assistance became important due to the limitations of public assistance. Public awareness also decreased that “emphasis should be placed on public assistance”, but the proportion of those who responded that “public assistance, mutual assistance and self-help should be balanced” increased. Second, due to the revision of the “Framework Act on Disaster Countermeasures” in 2014, the “District Disaster-Prevention Plan” for autonomous, local disaster -prevention activities was introduced. The characteristics of the “District Disaster- Prevention Plan” are ① bottom-up plans in which plans are established and proposed by residents. ② It is a plan that is directly prepared by a resident who is familiar with the current issues of the region and is in line with the reality and characteristics of the region. ③ It is a plan to enhance the disaster prevention capacity of the region based on the “District Disaster-Prevention Plan” by emphasizing the implementation of disaster prevention activities, regular evaluation, and continuity of disaster prevention activities. Third, since the implementation of the “District Disaster-Prevention Plan” in 2014, various disaster prevention organizations have been working to establish plans in various parts of Japan. There are various representative disaster prevention activities ① centered on residents' associations, neighborhood associations, and elementary schools, ② local disaster prevention activities centered on private businesses, and ③ those centered on universities.
The meaning of redundancy and consensus in quantum objectivity
Authors: Chisholm Diana A. , Innocenti Luca , Palma G. Massimo
Published: August 2023

While the terms "redundancy" and "consensus" are often used as synonyms in the context of quantum objectivity, we show here that these should be understood as two related but distinct notions, that quantify different features of the quantum-to-classical transition. We show that the two main frameworks used to measure quantum objectivity, namely spectrum broadcast structure and quantum Darwinism, are best suited to quantify redundancy and consensus, respectively. Furthermore, by analyzing explicit examples of states with nonlocally encoded information, we highlight the potentially stark difference between the degrees of redundancy and consensus. In particular, this causes a break in the hierarchical relations between spectrum broadcast structure and quantum Darwinism. Our framework provides a new perspective to interpret known and future results in the context of quantum objectivity, paving the way for a deeper understanding of the emergence of classicality from the quantum realm.

CO2 Hydrogenation to CH3OH on Metal-Doped TiO2(110): Mechanisms, Strain Effect and A New Thermodynamic-Kinetic Relation
Authors: Lu Huili , Yang Deshuai , Chen Zhao-xu
Published: August 2023

To develop low temperature catalysts for CO2 to methanol, CO2
hydrogenation to methanol on Znx@TiO2(110) (x = 0-2) was explored using
density functional calculations and microkinetic simulations. The
reaction mechanisms on the three model systems were determined and it is
shown that Zn2@TiO2(110) is most active. The most favorable pathway on
Zn2@TiO2(110) is identified and CO2 + H to HCOO is found to be the
rate-controlling step. It is demonstrated that there is a linear
relation (named AEB relation) between the adsorption energies of the
initial states and the barriers for the controlling step on the 17
systems studied. Calculations on strained surfaces show that the AEB
relation exists within ±1% strain, which is an effective way to improve
catalytic activity. Sr2@TiO2(110) and -1% strained CaZn and ZnCu doped
TiO2(110) are potential good low temperature catalysts and deserve
experimental testing.
Gender differences for left atrial volumes in apparently healthy Iraqi people.
Authors: Hussein Ismail Ibrahim
Published: August 2023

Background: The Left atrium (LA) structure and function had
recently gained increased interest as it potently predicts and indicates
cardiovascular (CV) risks and adverse outcomes in a range of CV
diseases. The purpose of this study is to assess the effect of sex group
on the structural and functional variations of the left atrium in
apparently healthy Iraqi people. Methods: Patients were split
into two groups according to their sex. Both groups were subjected to
routine history and clinical examination, a conventional 12-lead ECG
focusing on P wave assessment for shape, duration, and amplitude; PR
interval was measured. Also, a conventional, pulsed wave, and tissue
Doppler imaging (TDI) assessment were performed. Results: There
is a significant increase in A velocity, and a significant decrease in
E/A, and e‘/a‘ ratios, in females in comparison to males no significant
differences were observed in left atrial volume. Conclusion:
Although there is a significant impact of sex on the left atrial
contraction and diastolic function as there is a rise observed in “A
velocity” and a statistically significant drop in “E/A” and “e’/a”
ratios, which indicates an increase in atrial contraction during late
ventricular filling in females compared to males. However, sex group has
not proven to have a significant impact on LA volume. So, it must be
taken in consideration other factors like age, menopause, and obesity
indices together with sex which may permit the clarification of
diastolic dysfunction’s underlying processes and viable therapies.
A Hybrid Observer for Linear Systems under Delayed Sporadic Measurements
Authors: Guarro Marcello , Ferrante Francesco , Sanfelice Ricardo G.
Published: August 2023

This paper proposes a hybrid observer for state estimation over a
network. The network provides delayed measurements of the output of the
plant at time instants that are not necessarily periodic and are
accompanied by timestamps provided by a clock that synchronizes with the
clock of the observer in finite time. The proposed observer, along with
the plant and communication network, are modeled by a hybrid dynamical
system that has two timers, a logic variable, and two memory states to
capture the mechanisms involved in the events associated with sampling
and arrival of information, as well as the logic in the estimation
algorithm. The hybrid model also includes a generic clock
synchronization scheme to cope with a mismatch between the clocks at the
plant and the observer. Convergence properties of the estimation error
of the system are shown analytically and supported by numerical

Published: August 2023

Background : Metaplastic Breast Cancer (MpBC) is an exceedingly rare
entity, accounting for less than 1% of all malignant breast tumours.
Predominantly triple-negative, they are notorious for their
chemoresistance, high rates of recurrence and decreased disease-free
survival (DFS). All this contributes significantly to BC mortality and
results in poor prognostic implications. Limited evidence has led to a
lacuna of specific treatment guidelines for this entity and hence
remains an uncharted territory for clinicians. Case : We report a case
of left-sided low-grade metaplastic triple negative T3N2aM0 BC treated
with neoadjuvant chemotherapy, primary surgery, and adjuvant
radiotherapy, presently in remission. Conclusion : Limited experience in
management of this pathological entity warrants the need for more
research on it, with a special focus on targeted therapy. Discussing
possibilities of a tailored approach, rather than a one-size-fits-all
approach may aid in paving the path for the future of MpBC treatment.
A deep adaptive cycle generative adversarial neural network for inverse estimation of groundwater contaminated source and model parameter

In light of the challenges posed by groundwater contamination and the
urgent need for accurate and efficient groundwater contaminated source
estimation (GCSE), the present study proposes a novel approach for GCSE
using a deep adaptive cycle generative adversarial neural network
(DA-CGAN). Given the equifinality from different parameters (EFDP) often
associated with GCSE, we leveraged a bidirectional adversarial training
pattern involving a forward process and a recovery process to supervise
the inverse mapping relationship. Once trained, the forward process can
be utilized to provide estimation for GSCE. This bidirectional-training
strategy mitigates EFDP, thereby effectively enhancing the reliability
of GCSE. Moreover, the performance of DA-CGAN is closely related to the
quality of the training samples. To address this, we introduced a
significant enhancement through an adaptive sampling strategy. This
substantially improves the quality of training samples and consequently
increases the accuracy of the GCSE. Furthermore, the inherent
data-driven attribute of the deep cycle GAN considerably reduces
computational costs when conducting GCSE. The research unfolds in the
contexts of both hypothetical and real-world scenarios, with the goal of
providing an efficient, precise, and cost-effective solution for GCSE.
The results demonstrate that the DA-CGAN, an innovative model in the
hydrogeological domain, exhibits superior performance in both estimation
accuracy (Average Relative Error (ARE) of 4.91% and R of 0.998) and
computational efficiency (0.17 seconds per run). This is particularly
notable when compared with typical inverse methods such as the genetic
algorithm (GA) and the ensemble kalman filter (ENKF).

Published: August 2023

This work focused on how self-compacting concrete (SCC) performs in situ in hot weather conditions at an ambient temperature of about 35°C. Tests for the rheological properties and compressive and splitting tensile strength aspects were carried out. The results of SCC mix ingredients on the rheological and hardened features of SCC mix were studied. Variations in the amount of portland cement content (CC), water to cement ratio (w/c), coarse to fine aggregate ratio (C : F), chemical admixture ratio, and pozzolanic admixture ratio were considered. Optimum values were obtained for these ingredients, which satisfied the SCC rheological characteristics and gave a 28-day compressive strength of 42 MPa, and 52 MPa after 28 days and 56 days, respectively. These optimum constituent values were 450 kg·m–3 of cement, 0.45 water cementitious ratio, and a coarse to fine material ratio of 1 : 0.8, a high range superplasticizer of 2%, and a mineral admixture of either 5% silica fume or 25% fly ash as a substitute for a similar amount cement.
Developing an empirical model for assessment of total nitrogen inflow to rivers and lakes in the Biebrza river watershed, Poland
Authors: Canchig Jessica , Kustina Rinda , Grygoruk Mateusz
Published: August 2023

Nitrogen load is crucial for its application in various fields such as agriculture and improving water quality control for authorities responsible for establishing agricultural policies in the area. The calculation of nitrogen load using existing equations is not applicable for all types of rivers, thus requiring the development of a new equation that can be applied to lakes and rivers in the Biebrza river catchment. To determine the new equation, extensive mapping of the catchment area was conducted, which was adjusted to precipitation and runoff in the area, allowing the observed results to be compared. Based on several analyses, the new equation has better accuracy, RMSE of the new model-based estimation decreased by 65.9% in 2005–2015 and 62.2% in 2016–2021 for river and 92% in 2008–2019 and 95% in 2020–2021 for lakes. Therefore, the application of the new calibrated empirical model provides results close to the real values and it can be used in the Biebrza river basin to simulate the total nitrogen runoff.
Linguoculturological aspects of the lexeme cat in the Serbian language
Authors: Strbac Gordana , Stasni Gordana
Published: August 2023

The research was conducted in order to show the dominant models of thinking related to the word for ?cat? in the Serbian language community. The conceptualization of the cat was examined based on the meaning of lexical units: the lexeme cat and its semantic structure; the derivational network of this lexeme; the terminological expressions with the lexeme cat and the phraseologisms with this component. It can be stated that the analysis of linguistic data successfully reveals models of conceptualization of the ?cat? in the Serbian language community. The results show that both types of cognition of reality participate in the understanding of this animal - experience that is realized by the senses, and understanding, which engages the intellectual capacities.
A linguistic investigation of monosyllabic or masculine rhymes in Serbian poetry
Authors: Zec Draga
Published: August 2023

This paper focuses on the prosodic properties of monosyllabic, that is,
masculine rhymes in Serbian poetry. Word stress has been identified as a
crucial prosodic feature of Serbian rhyme in general, and of masculine rhyme
in particular, based on a quantitatively analyzed poetic database, which
includes eight poets, four from the Romantic and four from the post-Romantic
period. The role of stress is demarcative: it signals the beginning of the
domain of rhyme, thereby considerably promoting its effectiveness. However,
the presence of stress within the rhyme domain is not obligatory. The most
effective are resonant rhymes, with demarcated domains in both lines, next
in effectiveness are semi-resonant rhymes, with demarcation in only one of
the lines, while nonresonant rhymes, which lack demarcation, are the least
effective. Masculine rhymes are indistinct from feminine rhymes in terms of
their prosodic organization, but differ significantly in terms of their
linguistic realization. The lexical material provided by the Serbian
grammatical system is only partially adequate for realizing masculine
rhymes. The most effective resonant rhymes are formed exclusively by
monosyllabic words, which are an extremely rare prosodic profile in the
Serbian lexicon. On the other hand, the least effective nonresonant rhymes
are exclusively formed by polysyllabic words, which are a dominant prosodic
profile in the Serbian lexicon, but often yield infelicitous, barely
recognizable rhymes. It is notable that masculine rhymes are not used by all
poets in our database, which may well be due to the onerous lexical
constraints on their formation. Masculine rhymes are in fact used by only
four poets: three from the Romantic, and only one from the post-Romantic
period.
Third-Party Source Switches: Objective Valuation or Fair Value Opinion Shopping?
Authors: Koo Minjae , Sivaramakrishnan Konduru , Zhao Yuping
Published: August 2023

Fair value estimates from external third-party sources are generally considered more reliable than internal estimates based on managerial inputs. However, even externally sourced estimates are subject to managerial opportunism, because firms can switch from one external source to another. In the context of life insurance companies that mostly rely on external sources, we posit that such source switches could be driven by managerial incentive either to faithfully report fair values (objective valuation) or to inflate estimates to avoid OTTI (opinion shopping). Our results support both motives. In instances in which the two incentives yield conflicting predictions for source switching, we find the opinion-shopping motive dominates. We also find that switches that increase fair value estimates are associated with a reduced OTTI likelihood and magnitude, especially for high-impairment-risk securities. On balance, our evidence suggests that opportunism with respect to source switching can compromise the reliability of externally sourced fair value estimates.

Published: August 2023

En la actualidad, se desarrollan textiles técnicos basados en tecnologías que integran diferentes campos de la ciencia, como son el textil, la química y la electrónica. En la presente investigación, se realizó la funcionalización de textiles de algodón con óxido de grafeno reducido para mejorar su conductividad, buscando su integración en textiles técnicos/inteligentes. Se tomó como materia prima el grafito, que es transformado a óxido de grafeno por el método de Hummers modificado, y posteriormente reducido por métodos químicos y térmicos a óxido de grafeno reducido. Se evaluaron las propiedades de las partículas obtenidas mediante técnicas de espectroscopía UV-VIS, espectroscopía infrarroja FTIR y microscopía electrónica de barrido SEM, estas dos últimas para el textil y la partícula. El óxido de grafeno se depositó sobre fibras de algodón, y fue reducido empleando el método de agotamiento con ácido ascórbico. Se evaluó la funcionalidad en relación con la conductividad y los parámetros de calidad textil: masa por unidad de área, ensayos de solidez al color, protección UV y resistencia a la ruptura. Los resultados indican que la incorporación de este material en el textil proporciona una conductividad de 0,1477 S/m, lo que significa un aumento de esta en el textil de algodón, que, una vez funcionalizado, presentó un aumento en la resistencia a la ruptura, elongación y protección UV, acrecentando su espectro de aplicaciones en los diferentes campos de textiles técnicos, como hogar, transporte, trabajo, agro y medicina, entre otros.
