Accuracy of equivalent model in band-to-band tunneling simulation of semiconductor nanowires
Authors: Okada Jo , Mori Nobuya , Mil’nikov Gennady 
Published: January 2023

Abstract
The accuracy of the equivalent model (EM) in the band-to-band tunneling simulation of semiconductor nanowires is investigated by constructing EMs for various semiconductor nanowires and calculating the tunneling characteristics with the non-equilibrium Green’s function method. As the target window is widened, the EM accurately reproduces not only the traveling states but also the evanescent states. The relative error of the maximum tunnel current is shown to decrease exponentially with the transport window size. It is also shown that semiconductor nanowires can be classified into two types (D-type and I-type) according to the dispersion of the evanescent mode connecting the valence and the conduction band edges, and that the D-type nanowires can be represented with a smaller EM basis size or high accuracy compared to the I-type nanowires.

Abstract
Suppression of nonlinear signal generation in radiofrequency (RF) surface and bulk acoustic wave devices is one of the most important subjects for the RF front-end modules of recent cellular handsets. In particular, issues with second-order nonlinear products of bulk acoustic waves are well known. In this work, we succeeded in extracting the dominant parameters for second-order nonlinear analysis proposed by Hashimoto et al. [Joint Conf. European Frequency and Time Forum and IEEE Freq. Cont. Symp., 2017, p. 538] and verified that it is applicable in a wide frequency range and also effective for film bulk acoustic resonator (FBAR) device design. Combining the extracted nonlinear coefficients on the perturbation analysis by driving near the fundamental frequency (f0) and half resonant frequency (1/2f0) of the FBAR could reproduce second-order nonlinear characteristics in a wide frequency range. It was also confirmed that the proposed simulations are in good agreement with measurement results for various types of resonators and FBAR filters.

Abstract
In this study, optical-guiding crystal scintillator (OCS) and bundled plates were fabricated. Considering the performance and melting point of halide scintillators and the softening point of glass, Tl:CsI was selected as the fiber core and borosilicate glass as the cladding. Thus, the fabricated OCS had a scintillator in the core and glass in the cladding. The scintillator was remelted and unidirectionally solidified to remove the voids in the OCS and form a single crystal. Consequently, the OCS served as a scintillator fiber with excellent optical-guiding performance and high sensitivity to γ- and X-rays. An OCS plate was also fabricated using bundles of OCSs with diameters of several tens of microns. The developed OCS plate is expected to be a high-resolution and high-sensitivity imaging plate because of its excellent optical-guiding performance.
An approach to low-temperature oscillation and high efficiency of thermoacoustic prime mover: influence of end face and reduction area of phase adjuster
Authors: Matsumoto Takumi , Sakamoto Shin-ichi 
Published: January 2023

Abstract
The Phase Adjuster (PA) has contributed to the reduction of the onset temperature and improvement of the energy conversion efficiency of thermoacoustic systems. In this study, we investigated the performance characteristics of thin medal-shaped PAs representing the PA end faces. The results show that inserting 2 mm thick medal-shaped PAs lowered the onset temperature by 220 K. However, the insertion of thicker medal-shaped PAs maintained the onset temperature. In contrast, the energy conversion efficiency increased with the medal-shaped PA thickness. The energy conversion efficiency for 2 mm thick PAs was lower than that without PA. In addition, the thinner the medal-shaped PAs, the lower the power required for oscillation but the lower the energy conversion efficiency. These effects of the medal-shaped PA thickness indicate the necessity of different design guidelines for designing PAs for low-temperature oscillation and high efficiency in thermoacoustic systems.

Published: January 2023

Abstract
Ge-based nanosheets and GeH phases were synthesized in the vapor phase using CaGe2 crystals as templates. Ge-based nanosheets have been synthesized in the liquid-phase, but not in the vapor-phase. Compared with liquid-phase synthesis, vapor-phase synthesis is more useful for nanostructure control and impurity addition technologies. These technologies will increase the future popularity of nanosheets. And it is important to apply these technologies after clarifying the effects of certain parameters, such as annealing temperature and changes in the mole fractions. As an introduction to the future development of vapor-phase synthesized Ge-based nanosheets, this study proposes the thermal annealing of CaGe2 powders with MgCl2. Furthermore, the effects of changing the molar fraction containing Mg atoms and the behavior of HCl were investigated from 100 °C–600 °C.

<p>Short-reach fiber optical links employing intensity modulation (IM) at the transmitter (Tx) and direct detection (DD) at the receiver (Rx), suffer from linear and nonlinear sources of impairments due to the interaction of chromatic dispersion (CD) with DD. In this article, joint electronic dispersion compensation (EDC) at the Tx, using two distinct Gerchberg-Saxton (GS) based approaches, and at the Rx, using a functional link neural network (FLNN) equalizer is demonstrated for IM/DD transmission. The first Tx approach utilizes the modified iterative GS algorithm, which partially mitigate linear and nonlinear sources of inter-symbol interference (ISI). The second Tx pre-EDC approach only pre-compensates for the linear power fading effect through implementing a GS based finite impulse response (FIR) filter. At the Rx, a T/2-spaced or T-spaced adaptive post-feed forward equalizer (FFE) is employed to fully compensate residual chromatic dispersion prior to attempting nonlinear equalization. Furthermore, a Volterra nonlinear equalizer (VNLE) is introduced to benchmark the performance and complexity of the FLNN, Subsequently, either a FLNN or a VNLE are utilized for nonlinear system identification and subsequent post-equalization mitigating uncompensated nonlinear sources of ISI. The FLNN nonlinear taps resulting from the functional expansion block are optimized using the recursive least square (RLS) algorithm. The Tx-FIR and Rx-FLNN enable 112 Gbit/s non-return to zero (NRZ) on off keying (OOK) transmission over 20 km of single mode fiber (SMF) and 112 Gbit/s 4- level pulse-amplitude modulation (PAM-4) transmission over 10 km of SMF. It is shown that the use of Tx pre-EDC reduces the complexity of the required equalization at the Rx. In addition, the FLNN was found to offer a 74% reduction in computational complexity relative to the third-order VNLE.</p>

Building social resilience through visual instruments in Polish public space in the era of Russia's aggression against Ukraine
Authors: Dojwa-Turczyńska Katarzyna 
Published: January 2023

ObjectivesThe purpose of the article was an attempt to answer the question of the impact of murals created in Polish public space on building social resilience in the era of war in Ukraine.MethodsThe methodology of the conducted research was based on non-reactive research.ResultsThe results of the research showed the very rapid reactions of mural artists to the war in Ukraine. Works created in public space included both grassroots initiatives and mural painting supported by public entities and NGOs. Of interest was the presence of murals in public spaces in cities of different sizes, and the fact that they were created by both anonymous artists and authors who specialized in street art and were well-known in the community. Content analysis showed that the murals stigmatized the aggressor (Russia) and upheld the victim of the attack (Ukraine). They showed the heroism and bravery of Ukrainians, but also the trauma that war brings to hundreds of thousands of civilians and a country fighting for freedom. The murals showed who represents "good" and who represents "evil" in the ongoing conflict.ConclusionsThe murals were one of the instruments for building the social resilience of Poles against Russia's propaganda. Russia was presented on them as an aggressor, Ukraine as an invaded country. The message of the murals resonated in public spaces, but also in media spaces (newspapers, TV) and the Internet. Hence, their significance was broader than merely being present in the public spaces of individual cities.

Pink Tax: As a Form of Gender Identity in International Products?
Authors: Febriyanti Diavika , Yuwono Wisnu 
Published: January 2023

Knowledge about the existence of this Pink Tax is still very lacking in Indonesia. The Pink Tax weakens women's purchasing power by forcing them to spend more money on their daily needs, this creates unfair gender-based pricing. This study aims to analyze the effect of gender-based pricing, gender discrimination, gendered product marketing, price discrimination, and willingness to pay Pink Tax. This research method uses a primary data approach that is distributed to 263 people respondents, with the SmartPLS tool. The results of this research conclude that gender-based pricing only has an effect on Pink Tax, while gender discrimination, gendered product marketing, price discrimination, and willingness to pay do not have a significant effect on Pink Tax. These results indicate that brands often only take the opportunity to exaggerate women's goods and are considered the norm for women's consumption. It is also stated that gender discrimination is not only manifested in the form of price but can be directed in the form of diversification.

ABSTRAK
Kepala daerah bertanggungjawab sepenuhnya atas jalannya pemerintahan daerah. Dulu dipilih melalui DPRD, kini rakyat daerah yang memilih langsung dalam pemilukada. Sehingga kemudian dianggap kepala daerah lebih memperoleh dukungan nyata dari rakyat daerah. Namun, meskipun begitu bukan berarti kepala daerah menjadi kebal hukum dan dapat menghindari pemberhentian dari jabatannya, terlebih yang menjadi terdakwa dalam suatu tindak pidana kejahatan. Penelitian ini bertujuan untuk mengetahui alasan dapat dilakukan pemberhentian terhadap kepala daerah yang didakwa melakukan tindak pidana kejahatan. Dalam penelitian ini, peneliti mencermati isi undang-undang yang mengatur tentang pemberhentian kepala daerah. Adapun hasil dari penelitian ini dapat disampaikan bahwa pemberhentian kepala daerah yang berstatus terdakwa dilakukan dikarenakan sudah tidak lagi memenuhi persyaratan sebagai kepala daerah, melakukan perbuatan yang dilarang oleh undang-undang, dan melanggar sumpah jabatan kepala daerah.

Just wrong? Or just WEIRD? Investigating the prevalence of moral dumbfounding in non-Western samples
Authors: McHugh Cillian , Zhang Run , Karnatak Tanuja , Lamba Nishtha , Khokhlova Olga 
Published: January 2023

AbstractMoral dumbfounding occurs when people maintain a moral judgment even though they cannot provide a reason for this judgment. Dumbfounded responding may include admitting to not having reasons, or the use of unsupported declarations (“It’s just wrong”) as justification for a judgment. Published evidence for dumbfounding has drawn exclusively on samples of WEIRD backgrounds (Western, educated, industrialized, rich, and democratic), and it remains unclear to what extent the phenomenon is generalizable to other populations. Furthermore, the theoretical implications of moral dumbfounding have been disputed in recent years. In three studies we apply a standardized moral dumbfounding task, and show evidence for moral dumbfounding in a Chinese sample (Study 1,N= 165), an Indian sample (Study 2,N= 181), and a mixed sample primarily (but not exclusively) from North Africa and the Middle East (MENA region, Study 3,N= 264). These findings are consistent with a categorization theories of moral judgment.

Summary. The proposed work: To improve the results of surgical treatment of patients with acute peritonitis by developing a new aerosol remediation of the abdominal cavity.
Material and methods. A clinical and laboratory examination of 40 patients with acute disseminated peritonitis was carried out, a method of aerosol remediation of the peritoneal cavity with programmed relaparaperties was developed
The results. The developed method of aerosol sanitation of the peritoneal cavity with programmed laparotomy is the method of choice for treating patients with widespread forms of acute peritonitis. It creates opportunities for a long-term local influence on the course of the inflammatory process in the peritoneal cavity, allows to rehabilitate it, remove microorganisms and toxic products before they accumulate and generalize, and exclude their further action on the tissues of the peritoneal cavity.
Conclusions. The terms of programmed laparotomy should be determined individually, depending on the nature of the pathological process and the patient’s condition. However, at the initial stages of treatment, repeated exposures should be carried out no later than 72 hours, since the conditioned effect of ZL is maintained during this time. The use of the developed method of rehabilitation of postoperative wounds and cavities made it possible to reduce the number of programmed laparotomy to 3, with the final suturing of the abdominal cavity up to 8 days of the postoperative period.

El objetivo es analizar los factores de riesgo psicoemocional que potencian el síndrome de Burnout en Profesores universitarios. Se utilizó una metodología cualitativa, de tipo exploratoria y descriptiva en su alcance; a través del método de estudio de caso se aplicaron las técnicas de la observación, el análisis, el cuestionario y la entrevista estructurada a una muestra por conveniencia de 208 profesores de dos universidades públicas estatales de Sinaloa, México. Se parte de la interrogante ¿Qué factores determinan predominantemente los síntomas del síndrome de burnout en los profesores de la Universidad? Se encontró que entre los factores más significativos que potencian el síndrome del burnout, es la perdida de energía y agotamiento mental en el 41 % de los profesores universitarios consultados; seguido de la apatía en la relación con sus estudiantes del 11.6% de los entrevistados Se concluye, que entre los riesgos psicosociales que detonan el síndrome de burnout en el 71.2% (7 de cada 10 profesores universitarios) está la programación y aplicación de las actividades académicas fuera de horario laboral que demanda la atención a estudiantes y autoridades universitarias sumado al escaso apoyo recibido para el desempeño de las actividades académicas o la obstaculización de las mismas en la resolución de problemas académicos y científicos en el 21.0% de los casos. También se aplicaron 24 entrevistas estructuradas, en donde se encontró que son las mujeres y los profesores de tiempo parcial, quienes presentan más tendencia a desarrollar en burnout.
