Nanogap enhancement of the refractometric sensitivity at quasi-bound states in the continuum in all-dielectric metasurfaces
Authors: Watanabe Keisuke , Iwanaga Masanobu 
Published: January 2023

Abstract
All-dielectric metasurfaces have great potential as highly sensitive refractometric sensors relying on their spectral shifts because of an extensive range of design flexibilities and their smaller absorption losses than plasmonic platforms. However, simultaneously realizing both high quality (Q) factors and the large interplay of light with external medium in such photonic sensors remains one of the key challenges for their better performance. This study proposes silicon block metasurfaces with nanogaps to overcome this challenge based on quasi-bound states in the continuum (BICs). We show that the metasurface has two quasi-BIC modes—magnetic dipole (MD) and electric quadrupole (EQ)—and their electric fields experience large enhancement at the ∼30 nm nanogap regions. Consequently, introducing nanogaps into the metasurfaces increases the environmental refractive index sensitivity by up to 2.7 times in the MD mode while keeping the high Q factors and achieves the figure-of-merit (FOM) of 239. In addition, we show that the appropriate selection of the amount of asymmetry is needed under the trade-off between the FOM and spectral signal-to-noise ratio, which provides design guidelines for highly sensitive biosensors based on quasi-BICs.
Study on the preparation process and sintering performance of doped nano-silver paste
Authors: Yang Hui 
Published: January 2023

AbstractAfter tin–lead solders are banned, the widely used electronic packaging interconnect materials are tin–silver, tin–copper, and other alloy solders. With the application of high-power devices, traditional solders can no longer meet the new requirements. Nano-silver (Ag) paste, as a new solder substitute, exhibits excellent properties, such as excellent thermal and electrical conductivity, sintering at lower temperatures, and service at high temperatures. However, many organic devices still cannot withstand this temperature, and are often not suitable for the connection of nano-Ag paste packaging materials, therefore, it is very urgent to further reduce the sintering temperature of nano-silver paste. Based on the transient liquid phase sintering technology, by doping the nano-Ag paste with the nano-tin paste with a lower melting point to make the two uniformly mix, pressureless sintering at low temperature can be realized, and a sintered joint with a connection strength greater than 20 MPa can be formed. Considering that tin is easy to be oxidized, and the core–shell material can prevent the oxidation of tin, and at the same time ensure the uniform distribution of tin in silver, the doping scheme of the core–shell structure is determined. Heterogeneous flocculation method refers to the particles with different properties of charges which attract each other and agglomerate. It is a continuous reduction method for preparing core–shell materials. This method has the advantages of mild reaction conditions and less equipment investment, so the heterogeneous flocculation method is selected to prepare Sn@Ag core–shell nano paste. And research its sintering performance and strengthening mechanism.

AbstractLegionella pneumophila replicates in macrophages and amoeba within a unique compartment, the Legionella‐containing vacuole (LCV). Hallmarks of LCV formation are the phosphoinositide lipid conversion from PtdIns(3)P to PtdIns(4)P, fusion with ER‐derived vesicles and a tight association with the ER. Proteomics of purified LCVs indicate the presence of membrane contact sites (MCS) proteins possibly implicated in lipid exchange. Using dually fluorescence‐labeled Dictyostelium discoideum amoeba, we reveal that VAMP‐associated protein (Vap) and the PtdIns(4)P 4‐phosphatase Sac1 localize to the ER, and Vap also localizes to the LCV membrane. Furthermore, Vap as well as Sac1 promote intracellular replication of L. pneumophila and LCV remodeling. Oxysterol binding proteins (OSBPs) preferentially localize to the ER (OSBP8) or the LCV membrane (OSBP11), respectively, and restrict (OSBP8) or promote (OSBP11) bacterial replication and LCV expansion. The sterol probes GFP‐D4H* and filipin indicate that sterols are rapidly depleted from LCVs, while PtdIns(4)P accumulates. In addition to Sac1, the PtdIns(4)P‐subverting L. pneumophila effector proteins LepB and SidC also support LCV remodeling. Taken together, the Legionella‐ and host cell‐driven PtdIns(4)P gradient at LCV‐ER MCSs promotes Vap‐, OSBP‐ and Sac1‐dependent pathogen vacuole maturation.
Youth Out of Touch? Early Assessment of Millennial Leaders’ Performance on Human Capital Development at Indonesian Districts
Authors: Sardini Nur Hidayat , Wiryawan Bangkit Aditya , Martini Rina 
Published: January 2023

Starting in the second round of local election, participation of millenials has been increasing. The term refers to the young demographic cohort born between 1980 and 2002, known to have distinct characteristics to the previous generations. We gathered seventeen cases of elected millennial district heads between 2010 and 2017 and making an early observation of their impact on human capital development. Simplified difference-in-difference estimation method is applied using province average as the control group. Results show that following the winning of the millennial leaders there is a diverging trend of Human Development Index score at 0.03 and 0.07 in the first and second year, consecutively, before started converging around the third and fourth year. Lacking leadership skills and experiences, that may also be perpetrated by generational gap, are among the contributing factors to the problem. We further find that leaders not affiliated with political dynasty fare better. We check the robustness of our result using poverty data and further find that millennial leaders are also under-perform in combating poverty. This early assessment would benefit from further heterogeneity analyses as well as narrowing the control group, which is our recommendation for future research.

Published: January 2023

El trabajo de investigación que fundamenta esta publicación ha tenido como objeto de estudio conocer en qué medida el Olimpismo y su ideario estuvieron presentes en el devenir de la trayectoria deportiva y personal de Eloísa Marcos Quintano, gimnasta española en la década de los años sesenta y setenta, participante en los Juegos Olímpicos de Montreal-1976.

La metodología de este trabajo se ha estructurado a partir del análisis documental de la Carta Olímpica (edición 2020) extrayendo los valores que el ideario olímpico manifiesta implícitos en ese documento y contrastar el paralelismo de ese ideario con el esquema conceptual de las funciones que la actividad física y el deporte pueden cumplir, según publicó el profesor Juan L. Hernández Álvarez en Hernández-Álvarez y Velázquez-Buendía (1996). En base al resultado de los análisis documentales mencionados, se ha elaborado la estructura de un guion de una entrevista semiestructurada de final abierto (Hammer y Wildasky, 1990) que fue realizada a la atleta Eloísa Marcos, como fuente primaria oral protagonista de los hechos que pretendíamos rescatar. También se contrastaron los datos del testimonio recogidos en la entrevista con otras fuentes documentales principalmente hemerográficas.

Se presentan como resultado, las reflexiones y los análisis de los roles que el deporte desempeñó en la trayectoria deportiva de Eloísa Marcos Quintano, partiendo de los aspectos teóricos que el Ideario Olímpico pretende desempeñar con el deporte practicado a partir de su filosofía, así como, del análisis de cuáles han sido las funciones que en su particular circunstancia, ha desempeñado la actividad deportiva entre las expuestas por Hernández-Álvarez y Velázquez Buendía, (1996).

Published: January 2023

AbstractBackground and aimsThis research aimed to characterize social information processing abilities in a population of regular nondisordered poker players compared to controls.MethodsParticipants completed the Posner cueing paradigm task including social cues (faces) to assess attention allocation towards social stimuli, including the effect of the presentation time (subliminal vs supraliminal) and of the emotion displayed. The study included two groups of participants: 30 regular nondisordered poker players (those who played at least three times a week in Texas Hold'em poker games for at least three months) and 30 control participants (those who did not gamble or gambled less than once a month, whatever the game).ResultsThe group of regular nondisordered poker players displayed an enhancement of the inhibition of return during the Posner cueing task. This means that in valid trials, they took longer to respond to the already processed localization in supraliminal conditions compared to controls. However, our results did not evidence any particular engagement or disengagement attention abilities toward specific types of emotion.Discussion and ConclusionsThese results suggest that regular nondisordered poker players displayed social information processing abilities, which may be due to the importance to efficiently process social information that can serve as tells in live poker. The observed enhancement of the inhibition of return may permit poker players to not process a localization that has already processed to save attentional resources. Further research regarding the establishment of the IOR in other forms of gambling and with non-social cues needs to be performed.
Analysis of hydrochemical characteristics and genesis of water-deficient rivers in China: a case study of the Ciyao River Basin in Shanxi Province

Published: January 2023

In order to explore the chemical water characteristics of water-scarce rivers in China, the Ciyao River basin in Shanxi Province was taken as a case study. Water samples of the mainstream and its tributaries were collected in the wet, normal, and dry seasons of 2021. The composition and spatial variation of the main ions in the water body were analyzed using the ion chromatography (IC) instrument. In addition, Pearson correlation analyses were used to evaluate relevant correlation between ion concentrations. The results showed that the overall surface water in the study area was weakly alkaline, and the content of total dissolved solids (TDS) varied greatly, ranging from 702 to 5091 mg/L, with an average of 2897 mg/L. The TDS showed a middle stream > downstream > upstream trend, and the hydrochemical type was Cl • SO4 • HCO3 – Ca • Na. The contents of most ions were significantly changed based on differences in sampling sites and seasons. Natural and human factors influence the chemical characteristics of the river. According to the Gibbs diagram and Piper diagram (Figure 3), the ionic composition of the water body in the basin is mainly affected by the joint action of rock weathering and evaporative crystallization. Carbonate rocks constitute the most significant rock weathering, followed by evaporative and silicate rocks. Wastewater from industrial enterprises, agricultural wastewater, and activities of people’s daily living also have some influence on rock weathering. Cation exchange is also important in forming chemical water components in the Ciyao River. The research results can provide technical references and a basis for regional water environment protection, water resources development and utilization, and watershed eco-hydrology research.
On the issue of the management paradigm
Authors: Nazimko V. K. , Kudinova E. V. 
Published: January 2023

The current paradigm of specific knowledge, its quintessence are essential for experts and researchers. The industrial development of the world economy in the first half of the 20th cen- tury and the emergence of management caused the need for establishing its paradigm as well. All the researchers of management implicitly turn to this issue. However, few of them pay due atten- tion to the management paradigm. Lack of formalized structuring of management as a knowledge prove that the management paradigm is still being formulated. That is the reason for writing this article. The article presents the justification of the topicality of establishing the management paradigm. The authors define the main cause of variety of approaches to this issue, list objective and specific factors that influence the management paradigm and its evolution. The core atten- tion of the study is paid to system-based structuring of the basic sections of management as a knowledge for its further unification as a scientific discipline. On this basis, the authors analyze the completeness of the management paradigm presented by a foreign expert Peter Drucker at the beginning of the 21st century. They justify the expediency of the management paradigm de- velopment and its adaptation to the specific features of different countries with the consideration of significant specificity of national economies and management practices. The article contains the characteristics of the basic concepts of management peculiar for the contemporary Russia. The presented authors’ viewpoint on the formulation and interpretation of the management paradigm as a scientific knowledge may become a basis for developing the national management paradigm and preparing a rubricator of textbooks on management. The necessity and significance of the work can be justified by the fact that Peter Drucker and Henry Mintzberg, two well-known researchers and authors, have opposite views on the concept of management as a knowledge.

Authors: Widodo Mulyanto , Putrawan Gede Eka , Perdana Ryzal 
Published: January 2023

Numerous studies have been conducted to ascertain the relationship between the first language (L1) and the second/foreign language (L2). However, it is unclear how vowels and consonants affect how a foreign language speaker pronounces Indonesian. Thus, the objective of this study was to ascertain the vowels and consonants of the Indonesian language that were incorrectly and correctly pronounced by Lao men and Japanese women. This study is descriptive qualitative in nature. Following data collection via audio recording, the collected data were analysed using a contrastive analysis. The study's findings indicate that certain speech sounds are both mispronounced and well-pronounced. The speech sounds /i/, /u/, /e/, /ə/, /a/, /p/, /b/, /m/, /d/, /n/, /r/, /l/, /t/, /h/, and /k/ were mispronounced by the Japanese participants; however, the speech sounds /i/, /u/, /ə/, /a/, /ʤ/, /n/, /t/, /g/, /p/, /k/, /r/, and /h/ were not pronounced correctly by the Lao participants.

There have been significant advances in the technique and application of endovascular repair of thoracic aortic pathology over the past 20 years. The Stanford type A and the complicated type B dissection patients require urgent/emergent intervention. In the last decade, earlier intervention has been pursued for uncomplicated type B dissections. The INvestigation of STent-grafts in Aortic Dissection (INSTEAD) Long term (XL) study showed that there was significant crossover from medical management to Thoracic EndoVascular Aortic Repair (TEVAR) at year 3, suggesting TEVAR might benefit this population long term. Today, the application of TEVAR, which was initially designed to address aneurysmal disease, has become a standard and Food and Drug Administrative (FDA) approved management option in dissections. Currently there are four FDA approved TEVAR devices in the United States for the treatment of the thoracic dissections, namely Gore, Medtronic, Cook, and Terumo. With each iteration, there are increased opportunities for customization and widespread use in individualized patient’s pathology. As the technology improves and the feasibility of the grafts expands, the complication rates continue to decline cementing the safety and efficacy of these thoracic aortic grafts. Two rare but catastrophic complications in spinal ischemia and retrograde Stanford type A aortic dissection are further discussed. With the success of the TEVAR, a new frontier of hybrid aortic surgery has developed. The debranching of the aortic arch vessels in order to advance the TEVAR proximal landing zones has been aggressively pursued. With the widespread growth of TEVAR technology it is apparent that complex aortic pathology can be safely repaired endovascularly. Article Details
Immune Dysfunction as Measured by Lymphocytopenia, Minimal Residual Disease and Outcome after Radical Prostatectomy for Localized Prostate Cancer
Authors: Murray Nigel , Aedo Socrates , Fuentealba Cynthia , Reyes Eduardo , Salazar Anibal 
Published: January 2023

Background: An intact immune function may be important in eliminating or maintaining minimal residual disease latent. Objective: Use the absolute lymphocyte count as an immune biomarker, determine its association with minimal residual disease and relation with biochemical failure. Design, setting, and participants: prospective observational single centre study in men treated by radical prostatectomy for localized prostate cancer. One month after surgery blood and bone samples were taken to detect circulating prostate cells and micro-metastasis. A total of 404 men were enrolled, at each follow up time total PSA, ALC and CPC presence/absence were determined. Outcome measurements and statistical analysis: observed times to biochemical failure (Kaplan-Meier) and restricted mean biochemical failure free survival times were assessed, changes in the absolute lymphocyte count and the presence/absence of circulating prostate cells were determined during follow-up and association with biochemical failure. Results and Limitations: 404 men participated; 182 were minimal residual disease negative (Group A), 80 had only micro-metastasis (Group B) and 142 were circulating prostate cell positive (Group C); 175 men underwent biochemical failure, Group C were at high risk of early failure, Group B of late failure. One month post-surgery Group C men had lower absolute lymphocyte counts, compared to Groups A and B. During follow-up men with stable absolute lymphocyte counts did not relapse, a decreasing absolute lymphocyte count was associated with relapse within 18 months and the appearance of circulating prostate cells in the blood. After five years the absolute lymphocyte count decreased in Group B patients. A low absolute lymphocyte count one-month post-surgery or a decrease during follow-up was associated with an increased risk of treatment failure. Conclusions: the absolute lymphocyte count is an important prognostic factor, it may change with time, a decrease is associated with pending biochemical failure and later appearance of circulating prostate cells.
