A general framework for the inverse design of mesoscopic models based on the Boltzmann equation

Published: February 2021

Abstract
In this paper, we present a general framework for the inverse-design of mesoscopic models based on the Boltzmann equation. Starting from the single-relaxation-time Boltzmann equation with an additional source term, two model Boltzmann equations for two reduced distribution functions are obtained, each then also having an additional undetermined source term. Under this general framework and using Navier-Stokes-Fourier (NSF) equations as constraints, the structures of the distribution functions are obtained by the leading-order Chapman-Enskog analysis. Next, five basic constraints for the design of the two source terms are obtained in order to recover the Navier-Stokes-Fourier system in the continuum limit. These constraints allow for adjustable bulk-to-shear viscosity ratio, Prandtl number as well as a thermal energy source. The specific forms of the two source terms can be determined through proper physical considerations and numerical implementation requirements. By employing the truncated Hermite expansion, one design for the two source terms is proposed. Moreover, three well-known mesoscopic models in the literature are shown to be compatible with these five constraints. In addition, the consistent implementation of boundary conditions is also explored by using the Chapman-Enskog expansion at the NSF order. Finally, based on the higher-order Chapman-Enskog expansion of the distribution functions, we derive the complete analytical expressions for the viscous stress tensor and the heat flux. Some underlying physics can be further explored under this framework.

Abstract
Due to COVID-19, universities across Canada were forced to undergo a transition from classroom-based face-to-face learning and invigilated assessments to online-based learning and non-invigilated assessments. This study attempts to empirically measure the impact of COVID-19 on students’ marks from eleven science, technology, engineering, and mathematics (STEM) courses using a Bayesian linear mixed eﬀects model ﬁtted to longitudinal data. The Bayesian linear mixed eﬀects model is designed for this application which allows student-speciﬁc error variances to vary. The novel Bayesian missing value imputation method is ﬂexible which seamlessly generates missing values given complete data. We observed an increase in overall average marks for the courses requiring lower-level cognitive skills according to Bloom’s Taxonomy and a decrease in marks for the courses requiring higher-level cognitive skills, where larger changes in marks were observed for the underachieving students. About half of the disengaged students who did not participate in any course assessments after the transition to online delivery were in special support.

Abstract
Background: Changes in renal blood flow (RBF) may play a pathophysiological role in hypertension and kidney disease. However, RBF determination in humans has proven difficult. We aimed to confirm the feasibility of RBF estimation based on positron emission tomography/ computed tomography (PET/CT) and rubidium-82 (82Rb) using the abdominal aorta as input function in a 1-tissue compartment model. Methods: Eighteen healthy subjects underwent two dynamic 82Rb PET/CT scans in two different fields of view (FOV). FOV-A included the left ventricular blood pool (LVBP), the abdominal aorta (AA) and the majority of the kidneys. FOV-B included AA and the kidneys in their entirety. In FOV-A, an input function was derived from LVBP and from AA; in FOV-B from AA. 1-tissue compartmental modeling was performed using tissue time activity curves generated from volumes of interest contouring the kidneys, where the renal clearance of 82Rb is represented by the K1 kinetic parameter. To investigate the correct interpretation of K1, we assumed to first estimate effective renal plasma flow (ERPF) by extrapolating clearance values (ml/min/cm3) to whole kidney values (ml/min) using the estimated total kidney volume. Thereafter, RPF was estimated from ERPF using an assumed extraction fraction (0.89). Lastly, RBF was estimated from RPF using measured haematocrit values. Intra-assay coefficients of variation and inter-observer variation were calculated.Results: For both kidneys, K1 values derived from AA did not differ significantly from values obtained from LVBP, neither were significant differences seen between AA in FOV-A and AA in FOV-B, nor between the right and left kidneys. For both kidneys, the intra-assay coefficients of variation were low (~ 5%) for both input functions. The measured K1 of 2.80 ml/min/cm3 suggests, for young healthy subjects, an estimated total renal perfusion normalized to body surface area of 860 ± 129 ml/min/1.73 m2 and subsequently an estimated RBF of 1494 ± 221 ml/min/1.73 m2. Conclusion: RBF estimation based on PET/CT and 82Rb using AA as input function in a 1-tissue compartment model is feasible in a single FOV. The measured K1 clearance values are most likely representative of ERPF rather than estimated RBF values.
Promoter Methylation and Gene Expression of Pin1 Associated with the Risk of Alzheimer’s Disease in Southern Chinese
Authors: Ma Suk L. , Tang Nelson L.S. , Lam Linda C. Wa 
Published: February 2021

Background:
Pin1 is a propyl cis-trans isomerase and it has been associated with age-atonset
of Alzheimer’s disease (AD) and other pathological characteristics of AD. DNA methylation is
one of the gene regulation mechanisms and it might affect the gene expression.

Objectives:
This study was aimed to examine the correlation between DNA methylation and gene expression
of Pin1 and its effect on the risk of AD in a Chinese population.

Methods:
80 AD patients and 180 normal controls were recruited in this study and their cognitive
functions were assessed. Pin1 gene expression and methylation were quantified by real-time RT-PCR
and Melting Curve Analysis-Methylation assay (MCA-Meth), respectively.

Results:
Our finding revealed a positive correlation between methylation and gene expression of Pin1
(p=0.001) and increased Pin1 methylation was predisposed to the risk of AD (p<0.001). CG genotype
of Pin1 SNP rs2287839 was associated with higher gene expression of Pin1 (p=0.036) and the effect
was only prominent in normal controls as AD patients were already methylated at Pin1 promoter. Furthermore,
methylation of Pin1 was associated with better performance in cognition (p=0.018).

Conclusion:
Our result further supported the involvement of Pin1 in AD and the increased level of
Pin1 might be a protective factor for AD.

Published: February 2021

Background:
Ginkgo biloba is a common symptomatic treatment for cognitive impairment,
although data on its efficacy are controversial.

Objective:
The aim of the current study was to evaluate the effectiveness of standardized Ginkgo
biloba extract EGb761® (Tanakan®) for the improvements of cognitive functions over 24 months in
a local cohort of patients diagnosed with amnestic mild cognitive impairment (aMCI).

Methods:
This multicentre non-interventional study included 500 eligible patients with a MCI treated
with 120 mg/day standardized Ginkgo biloba extract EGb761® (Tanakan®). Patients were evaluated
using several scales for assessment of cognition, memory, activities of daily living, and depression
(MMSE, FAQ, CGI, HAM-D) at baseline and every 6 months after that for a 24-month period.
The median change in MMSE at the 24-month follow-up was the primary outcome of the
study.

Results:
A statistically significant increase of 2 points in the median MMSE score was obtained. In
patients with other concomitant cognitive disorders, the improvement in MMSE was less significant.
Tanakan® improved memory impairment (using the delayed recall test) and the ability to accomplish
activities of daily living (mean FAQ score, 1.7); it also decreased the severity of depression
(mean HAM-D score, 2.4) at the end of the study. More than 80% of the patients showed minimal
improvement of their condition as assessed by the CGI-Improvement Scale.

Conclusions:
The administration of EGb761® (Tanakan®) led to a significant improvement of cognitive
decline, memory, activities of daily living, and depression in subjects with aMCI over 24
months.

Background:
There are several potential advantages in optimizing the initial events of osseointegration in the benefit of clinical outcome.

Objective:
The objective of the present study was to evaluate the behavior of osteoblastic cells on surfaces treated by double acid etching using HNO3 and H2SO4.

Methods:
Commercially pure titanium (grade 4) discs measuring 6 mm in diameter and 2 mm in thickness were used. The discs were divided into two groups: machined group and double acid-etched discs (HNO3 and H2SO4). Surface characteristics were assessed using Scanning Electron Microscopy. Pre-osteoblastic MC3T3-E1 cells were used for cell culture on the tested surfaces to assess proliferation, viability (MTT), as well as secretion (ELISA) and cytoplasmic expression (Western blot) of type I collagen.

Results:
The data obtained were analyzed using t-test or two-way ANOVA followed by Bonferroni’s test at 95% significance. The titanium surfaces showed average roughness values for the machined and treated surfaces of 0.29 and 1.16, respectively (p<0.05). An increase in cell proliferation was observed, which was corroborated by the viability assay. Both type I collagen secretion and intracellular expression were higher on the double acid-etched surface compared to the machine surfaces (p<0.05).

Conclusion:
Implant surfaces treated by double acid etching positively affected the early events of the interaction between titanium and osteoblastic cells, suggesting optimization of osseintegration.

Published: February 2021

This paper aims to see the phenomenon of increasing mortality rates and birthrates during the Covid 19 pandemic. Pandemic Covid 19 has a lot of life, the number of victims worldwide reached 1.49 million people, and Indonesia as many as 17.199 people. To break the chain of the spread of the coronavirus, the Indonesian government has implemented a Large-Scale Social Restriction (PSBB) policy. The PSBB policy taken by the government at least influenced the increase in pregnancy rates, so a baby boom was predicted in 2021. The data in this paper comes from literature studies and relevant online newspapers. The results of this study are; 1) The cause of the high death rate due to Covid-19 is caused by individual factors and external factors. 2) The death rate has reached 17,081 with the number of cases 543,975 where Male groups are more prone to becoming victims of Covid 19 than women. Covid-19 victims in men are 55% higher than women. The high number of men exposed to Covid 19 is influenced by biological factors and social factors. 3) The birth rate has increased due to several supporting factors i.e the implementation of PSBB by the government resulted in more time with family, which led to an increase in pregnancy rates. Furthermore, access to health services is difficult so that many married couples do not visit health services for contraceptive programs until many women conceding and unplanned pregnancies.
Abstrak
Tulisan ini bertujuan untuk melihat fenomena peningkatan angka kematian dan peningkatan angka kelahiran selama masa pandemi Covid-19. Pademi Covid-19 telah menelan korban jiwa yang tidak sedikit, jumlah korban jiwa seluruh dunia mencapai 1.49 juta jiwa dan di Indonesia sebanyak 17,199 jiwa. Untuk memutus mata rantai penyebaran virus corona pemerintah Indonesia menerapkan kebijakan Pembatasan Sosial Berskala Besar (PSBB). Kebijakan PSBB yang diambil oleh pemerintah setidaknya telah memberikan pengaruh terhadap peningkatan angka kehamilan, sehingga diprediksikan akan terjadi baby boom pada tahun 2021 . Data dalam tulisan ini diperoleh dari studi literatur serta surat kabar online yang relevan. Hasil dari penelitian ini adalah; 1) Penyebab tingginya angka kematian akibat Covid-19 disebabkan oleh faktor individu dan faktor eksternal. 2) Angka kematian telah mencapai 17.081 dengan jumlah kasus 543.975 dimana kelompok laki-laki lebih rentan menjadi korban Covid 19 dibandingkan perempuan. Korban Covid-19 pada pria 55% lebih tinggi dibandingkan wanita. Tingginya angka pria terpapar Covid 19 dipengaruhi oleh faktor biologis dan faktor sosial. 3) Angka kelahiran yang meningkat karena beberapa faktor pendukung yaitu pelaksanaan PSBB oleh pemerintah mengakibatkan lebih banyak waktu bersama keluarga sehingga menyebabkan peningkatan angka kehamilan. Terlebih lagi, akses terhadap layanan kesehatan sulit sehingga banyak pasangan suami istri yang tidak mengunjungi layanan kesehatan untuk program kontrasepsi hingga banyak ibu hamil yang melahirkan dan tidak direncanakan.

Published: February 2021

Besides receiving education and teaching about the virtues of halal food according to the Melayu tradition, Riau community should also get an understanding of the virtues of halal food based on the Islamic law. This study aims to analyze the concept of the Riau Malay community in maintaining halal food, and what is the manners eat traditions of Melayu society closely related to eating etiquette in Islam. This research was a field study that collects data based on interviews, observation and documentation. The results showed that the food of the Melayu community has met the elements of halal and thoyyib as stipulated in culinary fiqh in Islamic law. The motive of the Melayu community to eat with halal and thoyyib criteria’s food is more due to habits and traditions that have been taught from generation to generation through the advice and teachings of the elders. This study also revealed that the type of food that is legalized is more than the type of food that is forbidden. Although the Malay community has been taught about the concept of halal food and thoyyib, but the teaching did not contain systematic content and had not yet reached a comprehensive level of understanding.
KONSTRUKSI SOSIAL ISLAM MODERAT JAMAAH MAIYAH MOCOPAT SYAFAAT PADA GENERASI MILENIAL DI YOGYAKARTA
Authors: Najib Khotim Hanifudin , Habibullah Achmad 
Published: February 2021

Understanding moderate Islam is very important to millennial Muslim generations in Indonesia. Today, this millennial generation is threatened by exposure to radicalism and intolerance, such as environmental studies, reading books and the Internet. This paper is a phenomenological study of the recitation of the congregation of intercessors Maiyah mocopat to inculcate moderate Islamic understanding in the millennial generation in Yogyakarta. The externalization of moderate Islam towards the millennial generation is achieved by creating a comfortable and enjoyable learning environment. Activities that occurred during this interfaith prayer session included Al-Quran, Shalawatan, Group Discussions, delivery of resource materials, sharing, and events interspersed with Kyai Kanjeng music performances. The activity makes the millennial generation have an objective understanding (objectivation) about peaceful Islam, soothing Islam, and moderate Islam. The internalization of moderate Islam is carried through primary socialization and secondary socialization. Primary socialization is carried in the family environment with the exemplary method. Whereas secondary socialization is carried in educational institutions such as schools, recitals, including through interfaith recitation sessions which held every 17th of the month
Migrant Labour Recruitment Reform in Malaysia: Towards Ethical and Zero-Cost Migration
Authors: Chin Low Choo 
Published: February 2021

The pressures exerted by migrant workers’ countries of origin, regional calls for migrant protection, and global initiatives have pushed the Malaysian government for labour reforms in line with International Labour Organization standards. A weak labour migration mechanism has led to human trafficking, debt bondage, and workers’ exploitation. Since 2018, Malaysia has concluded and renegotiated improved memoranda of understanding (MoUs) with countries of origin to address forced labour and human-trafficking. Reforming the recruitment system is formalised through government-to-government agreements to eliminate agents, enhance ethical recruitment, and adopt a zero migration-cost model. The analysis shows that the newly negotiated MoUs are significant in tackling the issue of irregular migration in three aspects, by including a clause on repatriation, changing to the government recruitment model, and adopting the employer-pays model. This research utilises official documents, media statements, and secondary literature.
Denial of the Rohingya Genocide: Problematising Daw Aung San Suu Kyi and the Rule of Law in Postcolonial Myanmar
Authors: P Cagape Wendell Gleen 
Published: February 2021

As the world condemns the genocide, Myanmar and Daw Aung San Suu Kyi’s government denied it and refused to accept it and argued that it sanctioned under the rule of law. This paper problematises these questions:, What is the rule of law in Myanmar? And why do they deny it? This study is qualitative in which pages of transcripts of speeches perused to find themes, settings, and meanings attributed to problematising Daw Aung San Suu Kyi and the rule of law in post-colonial Myanmar. These speeches delivered in public from 2016-2018. In analysing her speeches, the paper uses Foucauldian Discourse Analysis. On the part of Daw Aung San Suu Kyi, it found that problematising her actions and silence over the Rohingya genocide influenced her late father’s role. She continued to claim that her military father is the father of the Burmese military. She had special relations in incarceration with the army generals during her house arrest. She focused on the democratic transition which she promised in the 2015 election. This study reveals that this rule of law has purely political narratives because the generals are not accountable. This paper subsumes ongoing legal reforms in Myanmar.
