Authors: Benmeziane–Derradji Farida , Aoun Sara
Published: February 2023

The purpose of the study was to characterize (physicochemical properties, functional properties, antioxidant contents and biological activities) of two Algerian spices, turmeric and ginger. The results showed the richness of both spices in phytochemicals especially in polyphenols. Compared to ginger, which showed greater affinity for oil, turmeric powder had more affinity for water. In addition, turmeric swelled more (14.17 ml g-1) than ginger powder (8.33 ml g-1). The methanolic extract showed the highest total antioxidant activities of 470.72 ± 3.13 and 228.73 ± 42.19 AAE 100 g-1 for turmeric and ginger respectively. The aqueous extracts didn’t show anticoagulant activity while, the methanolic and acetonic extracts showed anticoagulant activity in a dose – dependent manner. As the butanolic extracts prevented the blood clot from forming, it could be used for medical application in future. Therefore, turmeric and ginger are a rich source of bioactive molecules and have functional and biological properties to be exploited in the food and pharmaceutical industry.

Published: February 2023

Paraspinal tumors are uncommon tumors involving the soft-tissue around the vertebrae. The lesion could originate from nerve roots, soft tissue, or blood vessels. The diversity of the lesions poses diagnostic dilemma, warranting robust histopathological diagnosis. We report such a case presenting with radicular pain due to paraspinal extramedullary hematopoiesis (EMH) masquerading as nerve sheath tumor. EMH is presence of hematopoietic tissue outside the bone marrow. EMH is usually seen as a compensatory mechanism associated with underlying hematological disorder. Our case presented primarily as paraspinal mass without underlying hematological disorder on evaluation. Thus, recognizing that EMH can present as paraspinal mass even without a diagnosis of pre-existing hematological disorder is crucial.
Development and content validation of an ADL questionnaire for hemiplegic shoulder
Authors: Chatterjee Subhasish , Goyal Manu
Published: February 2023

Objective:

Shoulder problems can be a common secondary musculoskeletal complication after stroke. Common post-stroke shoulder problems include altered muscle tone, pain, and a frozen shoulder. The study was aimed at formulating an activities of daily living (ADL) questionnaire for stroke patients with shoulder problems.

Materials and Methods:

The study was a cross-sectional content validation study conducted in a tertiary care hospital from August 2020 to March 2021. A literature review and direct patient interview were used to identify items for the scale. Before the construction of the scale, two physiotherapists with relevant field experience were interviewed to identify the items. Then, ten stroke patients were interviewed to generate new items depending on the challenges that they experienced. The scale was subsequently sent to a panel of eight experts for content evaluation.

Results:

After the first round of Delphi, we excluded the items that failed to achieve at least a 0.8 item-level content validity index (I-CVI). In the first round, 9 items fail to achieve 0.8 I-CVI hence removed from the actual draft of the scale. Total 10 items were included in the second draft and it was sent to the 2nd round of Delphi survey. In this phase, all items got more than 0.8 I-CVI. The average value and universal acceptance of the scale level content validity index have been obtained at 0.96 and 0.8, respectively. It denotes that our proposed questioner got excellent level of content validity.

Conclusion:

As the ADL questioner got excellent content validity, this scale can be used to assess the ADL functions of hemiplegic shoulder.

Dissociation of CO2 into C and O2
Authors:   AGH - University of Science and Technology, Cracow, Poland, M Pawlikowski
Published: February 2023

The objective of the research was to test the possibility of dissociating CO2 into C and O2 using electric discharges. An apparatus was designed and constructed for this specific purpose, and then CO2 was subjected to high-energy electrical discharges. After dissociation was completed, the gas “bombarded” with electric sparks was analyzed in a gas chromatograph. The obtained results indicate that about 17% oxygen, 72% nitrogen, and 0.9% Argon was obtained from dissociated CO2. About 8.5% of CO2 did not dissociate. The experiments and measurements of the obtained products, repeated several times, also revealed trace amounts of methane in the products of dissociation.
Economic, Social and Developmental Indicators (ESDI) to Measure Earthquake Recoveries in China
Authors:   Professor in Social Work and Social Administration, BNU-HKBU United International College, China, HCJ Wong
Published: February 2023

China is a country prone to disasters and earthquake is one of the continuous threats. Most serious recent earthquake was the Sichuan earthquake in 2008 and the earlier one was the Tangshan earthquake happened in the year of 1976. China was acknowledged for its “responses” in speedily mobilizing all resources to rescue. However little has been reported on the aspects of “recovery”, “mitigation” and “preparation”, the other three components in disaster management cycle. This paper aims to review the attempts in disaster management in China particularly on the part of government, by examining post-disaster economic growth and social developments, in the cases of four counties namely Wenchuan, Beichuan, Yushuand Yingjiang. The former two were the hardest hit areas during the Sichuan earthquake and the latter two were epic-centers of earthquakes in 2010 and 2011 respectively. Results of local GDP increases, population mobility and formation of social associations, showed that all counties have developed tremendously in term of economic production, however social progress has achieved less impressive growth. Volunteerism has emerged as a new phenomenon in these places and supported by the policies and legislations of the Central Government.
Improved Performance of Positive-ion mode Free Radical-Initiated Peptide Sequencing with para-TEMPO-Bz
Authors: Osho Kemi , Wasik Kimberly , Geary Laina , Borotto Nicholas
Published: February 2023

Free radical-initiated peptide sequencing (FRIPS) is a tandem mass spectrometry (MS/MS) technique that generates sequence informative ions via collisionally-initiated radical chemistry. Collision activation homolytically cleaves an installed radical precursor, initiates radical formation, extensive hydrogen atom transfer, and peptide backbone dissociation. While the FRIPS technique shows great promise, when applied to multiply charged derivatized peptide ions, a series of high abundance mass losses are observed which syphon ion abundance from radically generated sequence ions. This loss of ion abundance reduces the sequence coverage generated by FRIPS fragmentation. In this work, we hypothesized that these mass losses were assisted by the ortho-orientation of the radical precursor undergoing facile conversion into five- or six-membered intermediates or products and that when combined with the lower bond dissociation energy of the para-precursor, conjugated peptides would not undergo this chemistry. To test this assertion, we synthesized para-TEMPO-Bz, conjugated it to these peptides, and collisionally activated each. And indeed, we see dramatic attenuation of these undesired collisional processes and the significant increase in radical precursor ion abundance. The increase in ion abundance leads to a significant increase in the sequence coverage generated. These results demonstrate that p-TEMPO-Bz significantly improves the performance of positive-ion mode FRIPS and may be a compelling alternative to the currently utilized ortho-TEMPO-Bz-based FRIPS.
Dual nano-friction force microscopy/fluorescence microscopy imaging reveals the enhanced force sensitivity of polydiacetylene by pH and NaCl
Authors: Zheng Jianlu , Jo Seiko , Chen Jiali , Das Bratati , Juhasz Levente , Cabral Horacio , Sugihara Kaori
Published: February 2023

The nano-friction force microscopy and the fluorescence microscopy were combined to study the effect of pH and ionic strength on the polydiacetylene (PDA) force-sensitivity at the nanoscale. We found that the increase in pH from 5.7 to 8.2 caused an enhancement in the force sensitivity by 8 folds. The elevation of NaCl concentration from 10 mM to 200 mM also made the PDA 5 times more force-sensitive. These results suggest that the PDA force sensitivity at the nanoscale can be conveniently enhanced by pre-stimulation with pH or ionic strength.
Machine Learning-Boosted Docking Enables the Efficient Structure-Based Virtual Screening of Giga-Scale Enumerated Chemical Libraries

Published: February 2023

The emergence of ultra-large screening libraries, filled to the brim with billions of readily available compounds, poses a growing challenge for docking-based virtual screening. Machine Learning (ML)-boosted strategies like the tool HASTEN combine rapid ML prediction with the brute-force docking of small fractions of such libraries to increase screening throughput and take on giga-scale libraries. In our case study of an anti-bacterial chaperone and an anti-viral kinase, we first generated a brute-force docking baseline for 1.56 billion compounds in the Enamine REAL lead-like library with the fast Glide HTVS protocol. With HASTEN, we observed robust recall of 90% of the true 1000 top-scoring virtual hits in both targets when docking only 1% of the entire library. This reduction of the required docking experiments by 99% significantly shortens the screening time.In the kinase target, the employment of a hydrogen bonding constraint resulted in a major proportion of unsuccessful docking attempts and hampered ML predictions. We demonstrate the optimization potential in the treatment of failed compounds when performing ML-boosted screening and showcase HASTEN as a fast and robust tool in a growing arsenal of approaches to unlock the chemical space covered by giga-scale screening libraries for everyday drug discovery campaigns.

From paleontological data, conglomerates exposed on the northwestern shore of Lake Baikal, in the Bolshiye Koty and Listvyanka areas, belongs to the upper part of the section of the southeastern part of the Irkutsk coal-bearing basin (Angara-Koty depression) and is considered as part of the lower subformation of the Koty Formation dated back to the upper part of the Aalenian Stage of the Middle Jurassic (174–170 Ma). To identify a source of clastic material of the conglomerates, petrogenic oxides and trace elements of pebbles of volcanic rocks are determined and thin sections are examined. Defined are five groups of trachydacite-rhyolite pebbles of plumasite composition in the former outcrop and a group similar in composition to the main Bolshiye Koty group in the second one. The difference between the pebbles of conglomerates from the upper part of the section in the Angara-Koty depression and those of alkaline effusives of acidic and intermediate composition from the lower and middle parts of the section is indicated. It is assumed that the composition of the pebbles of the Upper Koty subformation is similar to that of the Middle Jurassic volcanic and subvolcanic rocks from Transbaikalia. Their origin from three sources is possible: 1) from nearest one – an unknown Middle Jurassic volcano buried under Cenozoic sedimentary stratum of the South Baikal basin, in the suture zone of the Siberian paleocontinent, 2) from the middle-remote one (distance over 250–500 km) – Middle Jurassic volcano-plutonic complexes of the Dzhida-Vitim fault zone, and 3) from the more remote one – the Mongolian-Okhotsk fault zone.

Methodology of interpreting the results of the interdisciplinary lingual-and-energetic research
Authors: Kalyta Alla , Klymenyuk Oleksandr
Published: February 2023

In this paper, the authors substantiate the specificity of a new method and methodological and technological procedures for a complex qualitative-and-quantitative description of the results of non-traditional interdisciplinary lingual-and-energetic studies of stochastic self-developing cognitive processes of human speaking-and-thinking activities. Methodological possibilities and rules of a comprehensive assessment of qualitative and quantitative aspects of these processes’ self-development are described in the paper. Using a theoretical principle of preserving the utterance’s emotional-and-pragmatic potential as well as the dimensionless K-criterion for defining the level of the utterance emotional-and-pragmatic potential, the authors work out the analysis method based on a psycho-energygram that presents the self-development of cognitive processes of speaking-and-thinking activities in the individual’s spiritual sphere. The trajectories of the analyzed processes’ self-development are considered from the standpoint of synergetic knowledge and thus are interpreted in the form of corresponding attractor structures with bifurcation points that acquire the cognitive status of concepts. The methodology described in the paper opens up new possibilities for a scientific quantitative description of the dynamics of self-developing processes of the individual’s speaking-and-thinking activities. These activities are viewed by the authors in their direct correlation with the reasons that actualize qualitative and meaningful acts generated by psychic and physiological bases of a person’s communicative behavior.

Published: February 2023

The present study was undertaken to investigate the survival of lactic acid bacteria (LAB)
in the fermented ceri Terengganu beverage and its antibacterial activity. The preliminary
study of the survival of five selected strains of LAB involved was Bifidobacterium
bifidum UABb-10™, Lactobacillus acidophilus DDS®-1, Lactobacillus paracasei UALpc
-04™, Lactobacillus plantarum UALp-05™, and Streptococcus thermophilus UASt-09™.
The viability of each strain was tested in fermented ceri Terengganu beverage (pH 3.25)
where all strains showed a survival rate of at least 92.5%. A total of five types of
foodborne pathogens namely Escherichia coli O517:H7 UPMEC32, Listeria
monocytogenes ATCC®
51772TM, Salmonella enterica serovar Enteritidis MDC15,
Salmonella enterica serovar Typhimurium ATCC®
53648TM and Streptococcus
gallolyticus ATCC®
9809TM were selected to determine the antibacterial activity and
minimum bactericidal concentration (MBC>99) of fermented ceri Terengganu beverage.
Antibacterial activity using the agar well diffusion method inhibited five tested food-borne
pathogens at varying extents of inhibition zone ranging between 12.92 to 18.50 mm in
diameter. Another antibacterial activity assay using the broth microdilution method also
confirmed the 100% inhibition effect of fermented ceri Terengganu beverage against these
selected pathogenic microorganisms even though the beverage has been diluted to 50%.
The synergetic effect of a significant amount of multiple organic acids present in
fermented ceri Terengganu beverages was the main factor contributing to its potent
antibacterial properties. This finding indicated the potential of fermented ceri Terengganu
beverage as a prebiotic beverage and might be able to reduce the risk of food poisoning
incidence as it has shown a good antibacterial effect against selected foodborne pathogens.
Effect of packaging materials and storage time on anthocyanins stability of red
cabbage-roselle mixed drink
Authors: Muhamad N.F.H. , Hussin F. , Arifin N.
Published: February 2023

This study aimed to investigate the effect of different packaging materials on
anthocyanins' stability of red cabbage-roselle mixed drink during 6-month storage. The
mixed drink was pasteurised and hot-filled into three different packaging materials, i.e.,
transparent glass bottle, beverage metal can, and polypropylene (PP) bottle, then stored at
ambient temperature (29±2°C). During storage, packaging materials and storage time
significantly affect the anthocyanin content, colour density, and polymeric colour
percentage of red cabbage-roselle mixed drink packed in a glass bottle, can, and PP bottle.
Polymeric colour percentage and degradation index of red cabbage-roselle mixed drink
were found to increase significantly during storage at the ambient temperature, whereas
total anthocyanin content and colour density decreased significantly irrespective of
packaging materials used. The correlation analysis reveals that total anthocyanin content
has a significant positive correlation with colour density but negatively correlates with
polymeric colour percentage and degradation index regardless of packaging materials
used. The total anthocyanin content decreases significantly irrespective of the packaging
materials used. The mixed drink in glass bottles significantly (p<0.05) has the highest
retention of anthocyanins content, followed by mixed drinks stored in cans and PP bottles.
Therefore, glass bottles should be chosen as the most suitable packaging material to store
the mixed drink, followed by cans and PP bottles as glass bottles provide better stability of
anthocyanins for a red cabbage-roselle mixed drink.
The physicochemical and thermal properties of unripe glutinous rice flour and
application in gluten-free noodle
Authors: Thongkaew C. , Singthong J.
Published: February 2023

The physicochemical and thermal properties of unripe glutinous rice flour (UGRF) and its
potential application in rice noodles were evaluated in this study. UGRF showed
dramatically higher protein content (10.57%) compared to glutinous rice flour (GRF) but
was lower in amylose content. The lower peak (1647.67 cP), breakdown (661.00 cP), final
viscosity (1208.33 cP), and setback viscosity (218.67 cP) were observed in UGRF
(p<0.05). Therefore, the solubility, swelling power, and water absorption capacity of
UGRF were higher than in glutinous rice flour. The onset, peak, final temperature, and
especially gelatinization enthalpy was significantly different (p<0.05) compared to
glutinous rice flour. Flour formulas for gluten-free noodle preparation were made by
substituting glutinous rice flour and tapioca flour with UGRF from 0-20% (by total flour
weight). The pasting properties of flour mixtures were significantly decreased with
increased UGRF content. The gluten-free noodle containing 5-20% of UGRF showed a
low cooking loss, high cooking weight, high maximum load, reflection at yield, and also a
green-yellow colour. The porous structure of dried gluten-free noodles was increased with
an increase in UGRF content, which affects the stickiness and springiness of noodles. The
addition of 5-10% of UGRF showed the most appropriate properties of making gluten-free
noodles with good cooking and textural properties including overall acceptance from
consumers and can be used as a healthy ingredient in a variety of noodles.

A presente pesquisa teve como objetivo levantar as percepções dos trabalhadores que passaram a realizar suas atividades laborais em home office durante a pandemia do Covid-19, bem como suas expectativas relativas ao período pós-pandêmico. Para esse fim, realizaram-se dez entrevistas em profundidade com teletrabalhadores de diferentes setores de atuação. Optou-se pela aplicação da técnica de Análise de Conteúdo para tratamento dos dados coletados. Examinando os resultados alcançados, verificou-se que a ruptura repentina e desestruturada do modelo de trabalho presencial, seguida pela adoção do home office, apesar de justificada devido ao avanço da pandemia, criou diversas dificuldades para os trabalhadores entrevistados, especialmente no que se refere à conciliação das demandas pessoais e profissionais. Complementarmente, constatou-se também que os participantes da pesquisa, devido à ausência de uma divisão clara, tanto física quanto temporal, entre a vida pessoal e o trabalho, passaram a estender a jornada laboral diária com frequência, o que os levou a um estado de esgotamento e estresse. Apesar dessas dificuldades, os entrevistados se mostraram favoráveis à permanência do home office mesmo após o fim da pandemia, demonstrando, em sua maioria, a preferência pelo modelo híbrido de trabalho. Este estudo contribui para a discussão acerca da necessidade de planejar adequadamente a migração do trabalho presencial para o home office ou vice-versa, de modo que esse processo ocorra de maneira harmoniosa e organizada, evitando a insatisfação profissional dos trabalhadores envolvidos e um eventual fracasso da adoção do teletrabalho.
Comparison of Linear Iteration Schemes to Improve the Convergence of Iterative Physical Optics for an Impedance Scatterer
Authors: Yoo Jeong-Un , Koh Il-Suek
Published: February 2023

The conventional iterative physical optics (IPO) method updates the surface current based on the Jacobi iteration scheme, which typically diverges for large objects. To control the convergence property of the IPO method, other iteration schemes, such as Gauss–Seidel and successive over-relaxation, can be used. In this study, we compare the convergence properties of three iteration schemes for scatterings by five scatterers comprising electrically perfect or imperfect conductors modeled with an impedance material. The accuracy of the IPO method is compared with that of the multi-level fast multipole method.

Published: February 2023

In this paper, a wideband ultra-low-profile solar cell–integrated antenna with a high form factor is presented. A copper indium gallium selenide-based solar cell was used for the proposed design. The solar cell was cut with a rectangular-shaped narrow slit to construct a built-in solar cell antenna with dimensions of 50 mm × 20 mm × 0.571 mm (0.382λo × 0.152λo × 0.0043λo at 2.28 GHz). The slit area needed to achieve a high form factor was only 0.5 mm × 18 mm. A coaxial-to-microstrip-line transition type of feeding structure was used to excite the antenna. An RF decoupler circuit was also designed under the second substrate to maintain the independent functioning of both devices. The simulated and measured results are in good agreement. Furthermore, the proposed design demonstrated a –10 dB impedance bandwidth of 42.45% with an ultra-low-profile structure of 0.0043λo at 2.28 GHz, and the maximum gain was 2.84 dBi in the impedance bandwidth range. In addition, the antenna has a high form factor of 99.1%, with no optical blockage.

Published: February 2023

A dual-band branch-line coupler with ultra-wideband harmonic suppression is proposed in this paper. The conventional quarter-wavelength transmission lines are replaced with π-shaped lines to achieve a dual band. In addition, ultra-wideband harmonic suppression is obtained by the frequency-selecting coupling structure (FSCS) providing three transmission zeros. The two operating frequencies are 0.9 GHz and 2.0 GHz, and the corresponding -10 dB bandwidth at 0.9 GHz and 2.0 GHz is 18.9% and 10.5%, respectively. A wide harmonic suppression band is generated from 3.7 GHz to 8.3 GHz. The simulation and measurement results are in good agreement.
AN ARTIST AND PRIVATE CUSTOMER IN THE 18TH-CENTURY PARIS. SURVEY ON THE DEVELOPMENT OF PORTRAIT PAINTING
Authors:   Moscow State Academy of Choreography, Agratina Elena E.
Published: February 2023

The interaction between a painter and his donator as a phenomenon of art history gives many opportunities to the research of social aspect of art. A private customer was isolated from any government institution such as the Academy of Painting and Sculpture. He did not pretend to be a connoisseur or adviser of painters but he had individual taste for art and his personally developed demands for it. As a field for dialog between painter and his patrons the portraiture appeared to become one of the most sought-after genres in 18th-century French society. The article aims to highlight a taste of an average French customer of the time showing how he wished to see himself and his loved ones on the canvas, what attributes he preferred to surround his person, how the client’s wishes coordinated with the creative ambitions and individual creative style of the artist were realized in the finished works .The author focuses on perception of the portrait painting by customers and some persons responsible to shaping and development of the ‘Academic doctrine’. The author of the article attentively scrutinized a wide gamut of sources, written by theoretical, critics, and connoisseurs, in which the tastes of private individuals and the painters who please them are subjected to a detailed critique. So the 18thcentury portrait painting is produced as a result of collaboration of painters and private customers whose identity, formed under a social and cultural impact, needed adequate expression in the arts.
IMMERSING THE THOUGHT IN A GRATEFUL MEMORY. PREFACE TO THE PUBLICATION: VANEEV A.A. LETTERS TO THE TEACHER
Authors:   Western branch of the Russian Academy of National Economy and Public Administration, Sharonov Vladimir I.
Published: February 2023

The article is a preface to a previously unknown text by A.A. Vaneev (1922–1985), a disciple and follower of L.P. Karsavin (1882– 1952), author of the book “Two Years in Abezi”, containing a philosophical portrait of the Russian religious philosopher. “Letters to the Teacher” became one of the first attempts of Vaneev to comprehend and present the ideas of Lev Karsavin, learned by the disciple as a result of long communication with his eminent interlocutor. Already that early text testifies to the philosophical sensitivity and gift of independent thought of Anatoly Vaneev, a recent convinced materialist, a pupil of the Soviet anti-religious education system. The meeting with Karsavin and immersion in his works led Vaneev to his own topics – clarifying the positive meaning of atheism and identifying the features of a new religiosity that has latently absorbed modern atheism. The article briefly analyzes the meaning of the idea of the heuristic meaning of dogmatics, as something most essential for understanding the reflections of both thinkers.

Published: February 2023

Poetics – a thing following ethics. That both philosophical and poetical formula belongs to Sigizmund Krzhizhanovsky. Any creative word, if it exists as a Word, holds an individual in being in all the disintegrations of cultural and social systems. But if the language space itself transforms into a paragraph, a subparagraph or clause emptied of meaning, man loses his reader-interlocutor and himself as an interlocutor either. The article studies a philosophical and poetical answer of Krzhizhanovsky on such ravage of culture as both creative and simply human environment that was perceived especially acute in Russia in the end of 1920-s

Ruqyah Jaranan And Its Resistance On The Dominant Culture
Authors: Anas Muhammad Nikmal Anas Alhadi
Published: February 2023

This paper discusses how Ruqyah Jaranan, a cultural event in East Java, is constructed as a resistance to the existing culture. It was typical that resistance appears from the weak side to the strong side. This case shows a resistance culture that was born from the strong to the weak culture. It specifically talks about the way Ruqyah Jaranan emerged in Kedawung Jember as a way to change the nature of the good young generation in that village. This paper argues that this event is an attempt from a particular people in dealing with what so called as “good young generation”. But the value of the culture has negotiated with the way the society in that village articulated the nature of the good young generation. This event has implications to shape the religiosity and morality of the young generation as behavior in daily life.

The configuration of a microwave switched radiometer is considered. The grounds that guide developers in determining the requirements for the ADC sampling rate are analyzed. It is shown that the ADC rate can be significantly reduced if an additional analog integrator is installed at the ADC input. Statistical modeling of such a circuit has been carried out, and the optimal parameters of the integrator have been determined. Calculations and laboratory tests of the microwave radiometer unit have been carried out. It is shown that the introduction of the simplest RC integrator makes it possible to use a low-speed ADC and leads to an insignificant change in the radiometer sensitivity.

Background: The stemness characteristics of cancer cells, such as self-renewal and tumorigenicity, are considered to be responsible, in part, for tumor metastasis. Epithelial-to-mesenchymal transition (EMT) plays an important role in promoting both stemness and tumor metastasis. Although the traditional medicine juglone is thought to play an anticancer role by affecting cell cycle arrest, induction of apoptosis, and immune regulation, a potential function of juglone in regulating cancer cell stemness characteristics remains unknown. Methods: In the present study, tumor sphere formation assay and limiting dilution cell transplantation assays were performed to assess the function of juglone in regulating maintenance of cancer cell stemness characteristics. EMT of cancer cells was assessed by western blot and transwell assay in vitro, and a liver metastasis model was also performed to demonstrate the effect of juglone on colorectal cancer cells in vivo. Results: Data gathered indicates juglone inhibits stemness characteristics and EMT in cancer cells. Furthermore, we verified that metastasis was suppressed by juglone treatment. We also observed that these effects were, in part, achieved by inhibiting Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1). Conclusions: These results indicate that juglone inhibits maintenance of stemness characteristics and metastasis in cancer cells.
Intracoronary Diagnostics in Patients with Acute Coronary Syndrome
Authors: Sun Qianhui , Liu Minghao , Zeng Ming , Jia Haibo
Published: February 2023

Despite the increasing number of coronary interventions in China, long-term adverse cardiovascular events remain high, especially in patients with acute coronary syndromes (ACS). The advent of intracoronary imaging and coronary physiological diagnostic techniques, such as optical coherence tomography (OCT), intravascular ultrasound (IVUS), near infrared spectroscopy (NIRS), and flow reserve fraction (FFR), has optimized the diagnosis and risk classification of patients with ACS. Intracoronary diagnostics compensate for the deficiencies of conventional coronary angiography in identifying and incriminating lesions and high-risk lesions. The combination of intracoronary imaging and physiological techniques is expected to achieve a comprehensive evaluation of the structural features and physiology of the coronary arteries, thus further tailoring and improving the prognosis of patients.
Coupled systems of subdifferential type with integral perturbation and fractional differential equations
Authors: BOUABSA Aya , SAIDI Soumia
Published: February 2023

This paper is mainly devoted to study a class of first-order differential inclusions governed by time-dependent subdifferential operators involving an integral perturbation. Employing then the constructive method used there, we also handle the associated second-order differential inclusion.

Our final topic, accomplished in infinite-dimensional Hilbert spaces, is to develop some variants related to coupled systems by such differential inclusions and fractional differential equations.
Topic Analysis Reveals First Impressions of Voices
Authors: Ostrega Jessica , Feinberg David R.
Published: February 2023

People form rapid first impressions when encountering novel faces or voices. A popular theory on first impressions suggests there are two dimensions on which voices and faces vary: valence and dominance. Studies using orthogonal factor rotation, consistently find a third dimension in face space. However, participants are always given the same questionnaire. Unconstrained descriptions of female voices and faces from free-form responses have been tested but rely on researchers’ opinions to categorize descriptions. To shift researcher degrees of freedom away from category membership, we used machine learning to categorize free responses to 50 female and 50 male voices saying ‘hi’. We found a rich set of features that people use to categorize voices that does not reduce to valence and dominance, suggesting that while these traits are important to researchers, they are not as important to participants.

Trends in Developmental Gradient in Mothers’ Childcare Time by Maternal Education, 2003-2019
Authors: Gao Melody Ge
Published: February 2023

There has been a convergence in childcare time between more- and less-educated mothers in the United States after 2000, driven by less-educated mothers’ faster rates of increasing their childcare time. Researchers have proposed the diffusion of intensive mothering ideology to lower-SES mothers as one potential mechanism for this convergence, but this hypothesis has not been tested. This study applies a developmental framework of maternal time investment — mothers invest more time in developmentally appropriate childcare activities at children’s specific ages than other ages — to empirically investigate this question. Using the American Time Use Survey (ATUS) from 2003 to 2019 (N = 34,232), this study examines whether the educational differences in developmental gradients were narrowing, which would be consistent with a cultural diffusion pattern. Results show that in 2003, mothers with bachelor’s degrees were more likely than mothers with less education to follow the developmentally appropriate time investment. By 2019, above and beyond correlated demographic and employment factors, less-educated mothers’ time investment in childcare was in line with the developmental gradient, which was similar to the pattern for mothers with bachelor’s degrees. This study adds evidence for a cultural explanation to the flattened educational gradient in mothers’ childcare time.
Innovations in stock matching and allocations: the social housing challenge

Published: February 2023

This project examines whether current social housing allocation and matching policies and practices meet the needs of applicants or tenants and maximise social housing sector performance and efficiency outcomes. It looks at how to optimise housing stock allocations based on individual needs (including the role of support) and neighbourhood and community needs (avoiding concentrations of disadvantage and potential antisocial behaviour).‘Allocation’ is the rationing of access to social housing, and ‘Matching’ is the process of trying to best fit the requirement of allocated households with the attributes of the available stock—including size, location and service access, as well as in terms of community harmony and individual wellbeing.The research reviewed international and Australian policy, interviewed stakeholders across four jurisdictions (QLD, VIC, TAS and SA), developed an evaluation framework (Social Return on Investment - SROI) for housing allocation strategies.The international policy review suggests the Choice-based lettings model could enhance tenants’ choice and reduce stigma; local allocation plans could improve tenant composition and social mix in specific neighbourhoods; policies to address underutilisation of social housing should be carefully considered; and programs integrating support services onsite to address tenants with complex needs should be more widespread. The research findings suggest Governments should view the social housing sector as part of the larger housing market rather than as a separate, standalone system. The sector would benefit from expanding its limited target from tenants with highest need for housing integrated with other support, through to people with high need for housing but no need for other support, to people in need of affordable housing only in various forms.
