A new approach to rheological properties of waxy crude oils using the tree-based machine learning methods
Authors: Meighani Hossein Mashhadi , behbahani Taraneh Jafari , Dehghani Amin
Published: December 2022

In this work, the rheological behavior of three crude oils, with low,
middle and high wax content, in the absence/presence of polymeric and
aromatic flow improvers was investigated. The rheological data cover the
temperature range of 0 to 60 °C to include the wax appearance
temperature (WAT). The results indicated that EVA copolymer has
remarkable performance in change of flow behavior from non-Newtonian to
Newtonian even at temperatures below WAT. Moreover, the addition of
small quantities of asphaltene solvents such as toluene can improve
viscosity of crude oil with high wax content. In addition to
experimental and analytical modeling investigations, this work attempted
to model measured shear stress and viscosity of waxy crude oils using
tree-based machine learning methods and consider wax content and
additives concentration as input parameters of models. Amongst all
implemented techniques, Extra Trees model performed as a potential
predictor in waxy oils rheology studies.

Authors: Wang Shutao , Hao Y. P. , Ba S. H. , Wang Di
Published: December 2022

The existing cocrystal preparation of CL-20 is difficult to form
large-scale production. And new ligands and processes are needed to
change the current situation. Molecular dynamics simulation was
performed on CL-20/DNDA7(3.5-dinitro-3.5-diazaheptane) and CL-20/HMX
cells. Radial function analysis, Hirshfeld surface comparison analysis,
and growth simulation analysis were performed on the simulation results.
The results show that: Decreasing the temperature is beneficial to
increase the strength of the hydrogen bond of CL-20/DNDA7 cocrystal,
especially at 203K; The maximum initiation N-N bond length is smaller
than that of CL-20 crystal and CL-20/HMX cocrystal; The hydrogen bond
interaction of CL-20/HMX cocrystal is lower than that of CL-20/DNDA5 and
CL-20/DNDA7 cocrystal. Decreasing the temperature is beneficial to
cocrystal formation. The sensitivity of CL-20/DNDA7 is lower than that
of CL-20 and CL-20/HMX cocrystal. CL-20 is more likely to form hydrogen
bonds with linear nitroamine explosives than CL-20/HMX. Keywords:
cocrystal; Molecular dynamics simulation; hydrogen bond interaction;
sensitivity

Insilico structural characterization and phylogenetic analysis of Nucleoside diphosphate kinase: A novel anti-apoptotic protein of Porphyromonas gingivalis
Authors: Singh Ajay Kumar , Singh Suchitra , Yadav Piyush Kumar
Published: December 2022

Nucleoside diphosphate kinase (NDK) protein of Porphyromonas
gingivalis (P. gingivalis) plays an important role in immune evasion
and apoptosis inhibition of host cells. It has the potential to cause
cancer, however, its structure has not yet been determined. Here we
established a 3D structure of P.gingivalis NDK protein using an
in-silico approach and performed the structural analysis of the model
protein. 3D structure of NDK was predicted through homology modelling
using modeller. Structural domains predicted for the model belongs to
the NDK family. Structural homology was further confirmed by functional
annotation of the model which includes ATP binding and nucleotide
diphosphate kinase function, indicating that it is an NDK protein.
Structural alignment of the putative model shows the alpha-beta folds
are structurally conserved among NDK from prokaryotes and eukaryotes.
The structure-based phylogenetic analysis depicts a significant
evolutionary relationship of the modeled protein with the NDK of
prokaryotes. Furthermore, the MD simulation approach stabilized the
model structure and provides a thermo-stable protein structure that can
be used as a therapeutic target for further studies.

Aquatic bird species richness and distribution in relation to reservoirs' limno-chemistry in Tigray National Regional State, northern Ethiopia
Authors: Haileselasie Tsegazeabe
Published: December 2022

Summary 1. Knowledge of the relationship between biodiversity and
environmental factors provides insight into patterns of species richness
and distribution in limnetic ecosystems. To this end, this study was
conducted to test the effect of limnological characteristics of
reservoirs on bird species richness and distribution along an age
gradient of limnetic ecosystems in Tigray National Regional State. 2. To
evaluate the relationship between limnological characteristics of
reservoirs and patterns of bird species richness and distribution, six
physicochemical variables, three morph-edaphic and biological variables
were recorded for 35 reservoirs and analyzed by multivariate statistical
techniques. Species richness data was subjected to a multiple regression
analysis at limnological variables, biological variables and age of the
reservoirs in order to investigate the most important explanatory
factors influencing avian species richness and their distribution using
Redundancy analysis (RDA). 3. 85 bird species from 54 genera, 25
families and 15 bird orders were recorded, with mean species richness
14.236.72 (mean  standard deviation) per reservoir. Five of these
species are near threatened (NT) while other two species fall under
critically endangered (CR) and vulnerable (VU) conservation status
designations, respectively. Bird species richness was positively
correlated with surface area of reservoirs. The RDA analysis identified
two significant RDA axis and 34.4% of the variation in species richness
is explained by environmental variation (R2adj = 0.34375; P <
0.001). Generally, water chemistry appears to play only a minor part in
affecting bird species richness in reservoir in Tigray, Northern
Ethiopia. However, chemical variables may be helpful to distinguish
between used and unused sites for some species. 4. The result provides
an important insight on the ecological relationship between waterbirds
species richness and limnological characteristics of reservoirs. And
plays a role towards strengthening our knowledge on aquatic bird ecology
and natural history of African Eurasian Migratory waterbirds.

Published: December 2022

Understanding the evolutionary consequences of anthropogenic change is
imperative for estimating long-term species resilience. While
contemporary genomic data can provide us with important insights into
recent demographic histories, investigating past change using present
genomic data alone has limitations. In comparison, temporal genomics
studies, defined herein as those that incorporate time series genomic
data, leverage museum collections and repeated field sampling to
directly examine evolutionary change. As temporal genomics is applied to
more systems, species, and questions, best practices can be helpful
guides to make the most efficient use of limited resources. Here, we
conduct a systematic literature review to synthesize the effects of
temporal genomics methodology on our ability to detect evolutionary
changes. We focus on studies investigating recent change within the past
200 years, highlighting evolutionary processes that have occurred during
the past two centuries of accelerated anthropogenic pressure. We first
identify the most frequently studied taxa, systems, questions, and
drivers, before highlighting overlooked areas where further temporal
genomic studies may be particularly enlightening. Then, we provide
guidelines for future study and sample designs while identifying key
considerations that may influence statistical and analytical power. Our
aim is to provide recommendations to a broad array of researchers
interested in using temporal genomics in their work.

Authors: Aparajita Aparajita , Gupta Sangeeta , Prasad Sudha , Garg Anju , Kapoor Seema
Published: December 2022

Objective- To assess the potential effect of Chorionic Villus Sampling
(CVS) on placental perfusion by examining change in uterine artery
pulsatility index (UtA-PI) between first and second trimesters of
pregnancy. Design- It was a prospective observational study conducted
between August 2017 to January 2019. Setting- Department of Obstetrics
and Gynecology, Maulana Azad Medical College, New Delhi. Study Sample-
Twenty-one singleton pregnancies where CVS was planned were included in
the case group whereas forty-two low-risk singleton pregnancies with no
invasive testing constituted the control group. Pregnancy resulting in
miscarriage or, termination of pregnancy for affected fetus, or demise
of fetus beyond 23 weeks or subsequent detection of anomaly or
chromosomal defects were excluded. Methods- Dating scan along with first
and second trimester UtA doppler study was done at 11-13+6 weeks and
22-24+6 weeks respectively using an ultrasound machine with 2-5 MHz
trans-abdominal transducer. Main Outcome Measures- The primary outcome
was to evaluate the change in UtA-PI between first and second trimesters
of women undergoing CVS and comparing it with control group. Results-
The difference between first and second trimester mean PI of case and
control group were 0.71± 0.35 and 0.44± 0.45 respectively. This
difference of fall in PI between the two groups was statistically
significant (p= 0.010) with the change being higher in the CVS group.
Conclusions- CVS does not cause undesirable effect on the UtA doppler.
UtA doppler being a predictive marker of development of pre-eclampsia or
FGR; this study affirms the safety of CVS in experienced hands.

Black-tailed deer resource selection reveals some mechanisms behind the ‘luxury effect’ in urban wildlife
Authors: Fisher Jason , Fuller Hugh , Hering Adam , Frey Sandra , Fisher Alina
Published: December 2022

The global urban population is expected to increase by 2.5 billion
people over the next 30 years. Yet the doubling of urban landscapes in
the last decades have already led to habitat loss and concomitant
impacts to biodiversity. Nonetheless urban landscapes remain important
for wildlife, and global syntheses have revealed that wealthy urban
areas house more biodiversity, a ‘luxury effect’. We researched some of
the mechanisms for the luxury effect for urban black-tailed deer, a
species of increasing concern in urban landscapes across the
northwestern Nearctic. We satellite collared twenty deer in an urban
landscape in British Columbia, Canada, with high-resolution fix rates.
We used generalized models in an information-theoretic framework to
weigh evidence for competing hypotheses about the role of tree cover,
productivity, public green spaces, and wealth in explaining deer
selection. Wealth, manifesting as housing lot size, emerged as the
dominant predictor of deer space-use, which is highly concentrated into
very small home-ranges. Other landscape elements stemming from
affluence, including golf courses and parklands, were also strongly
selected by deer. We show post-colonization landscape conversion from
dry semi-arid savannah to well-watered high-productivity landscapes is
supporting deer, with ramifications for the rest of the biotic
community. With urban landscapes becoming an increasingly important for
biodiversity conservation, understanding these mechanisms can help to
promote wildlife-human coexistence.
A review on Vision-based Human Action Recognition
Authors: Li Ping , Singh Dheeraj , Gupta Abhinav , Chan Boyi
Published: December 2022

Vision-based human action recognition is the process of labeling image sequences with action labels. Robust solutions to this problem have applications in domains such as visual surveillance, video retrieval and human-computer interaction. The task is challenging due to variations in motion performance, recording settings and inter-personal differences. In this survey, we explicitly address these challenges. We provide a detailed overview of current advances in the field. Image representations and the subsequent classification process are discussed separately to focus on the novelties of recent research. Moreover, we discuss limitations of the state of the art and outline promising directions of research.
Using the stochastic-threshold incision model to understand the tectonic expression on fluvial topography: theory and application to the Dadu River basin, eastern Tibetan Plateau
Authors: Wang Yizhou , Zheng Dewen , Zhang Huiping
Published: December 2022

The non-linear reliance of channel steepness on erosion rates can be
reconciled by the stochastic-threshold incision model that incorporates
river incision threshold and discharge probability distribution into
erosion efficiency. Here, we explored the usage of the model in river
longitudinal profile inversion, by assuming time-dependent tectonic
forcing and a linear exponent that relates channel incision to slope. We
developed an analytical solution to the model equation and an inverse
scheme to retrieve relative uplift rate history, whose validity was
based on the theoretical demonstration on knickpoint preservation.
Application of the inverse scheme to the main trunks of the Dadu River
basin in the eastern Tibetan Plateau produced a history with two-phase
increases in the uplift/incision rates, which is similar to the results
from low-temperature thermochronology. Thus, our analytical procedures
provide new insights into the link of tectonic uplift and river profile
evolution, when channel steepness depends on erosion rates
non-linearly.

Objective

Analyse the impact of modern glucose-monitoring strategies on glycemic and patient-related outcomes in individuals with type 2 diabetes (T2D) and recent myocardial infarction (MI), and also assess cost effectiveness. 

Research design and methods

LIBERATES was a multicentre, two-arm randomised trial comparing self-monitoring of blood glucose (SMBG) with intermittently scanned continuous glucose monitoring (isCGM), also known as flash CGM, in individuals with T2D and recent MI, treated with insulin and/or sulphonylurea prior to hospital admission. 

The primary outcome measure was time in range (TIR; glucose 3.9-10 mmol/l)/day on days 76-90 post randomisation. Secondary and exploratory outcomes included time in hypoglycemia, hemoglobin (Hb)A1c, clinical outcome, quality of life (QoL) and cost effectiveness. 

Results 

Of 141 participants aged [median 63 IQR (53, 70) years, 73% males] randomised, isCGM was associated with increased TIR by 17mins/day (95% credible interval -105, +153mins/day) with 59% probability for a benefit. Users of isCGM showed lower hypoglycemic exposure (<3.9 mmol/l) at days 76-90 [-80min/day (95% CI: -118, -43)], also evident at days 16-30 [-28min/day (-92, 2)]. Compared with baseline, HbA1c showed similar reductions of 7 mmol/mol at 3 months in both study arms. 

Combined glycemic emergencies/mortality occurred in 4 isCGM and 7 SMBG study participants. QoL measures marginally favoured isCGM and the intervention proved to be cost-effective. 

Conclusions

Compared with SMBG, isCGM in T2D individuals with MI marginally increases TIR and significantly reduces hypoglycemic exposure while equally improving HbA1c, explaining its cost-effectiveness. Studies are required to understand whether these glycemic differences translate into longer term clinical benefit.

Primary students' math literacy is still inadequate. This is due to the limited number of problems based on math literacy, while studies analyzing math literacy require high-order thinking skills (HOTS). This study aims to develop instruments and analyze primary students' math literacy by reviewing high order thinking (HOTS). The study participants were 30 fifth-grade primary school students by grouping students into three HOTS levels: low, medium, and high. The study method uses a mixed-method (quantitative and qualitative) with an explanatory sequential design. The research instrument is an initial math literacy test (ML-T) that focuses on content, context, process, and level. Data analysis used descriptive statistics. The results of the study resulted in 15 ML-T which had been declared valid and reliable, divided into 6 items at levels 1-2 (easy), 5 items at levels 3-4 (enough), and 4 items at levels 5-6 (hard). The results of another study show that the success of primary students' math literacy depends on the level of ML-T problems and students' HOTS abilities. Higher ML-T levels tend to be completed with math literacy in the perspective of higher HOTS levels of students. This study's implication is to contribute to developing authentic math literacy instruments and analyzing the success of primary students' math literacy by looking at the HOTS level.

New phosphorus-containing polyesters based on N-derivatives of dicarboxylic α-amino acids and diols of the polyoxyethylene series in which the phosphate group has been introduced are synthesized, capable of forming self-stabilized dispersions with nanosized particles of the dispersed phase in aqueous media. The introduction of the phosphate group in the hydrophilic fragment significantly increases the stabilizing ability. The properties of new phosphorus-containing polyesters allow us to consider them as potential systems for drug delivery.

A Microbial Fuel Cell (MFC) is an electrochemical system that generates energy utilizing waste as a substrate and the results of microbial metabolism processes. This research utilizes yeast fermented cassava waste as a substrate to determine the electrical characteristics of PEM in the form of a chitosan-carrageenan membrane and salt bridge. The cassava waste is from the waste produced in the manufacture of tapioca flour. A dual-chamber MFC made of acrylic with a size of 8x8x10 cm is used. Cassava waste substrate with carbon electrodes would be in the anode compartment, and seawater electrolyte with Cu(Ag) fiber electrodes would be in the cathode compartment. Each measurement holds ±250 ml in each compartment. The MFC system consists of 10 cells and is analyzed every hour for 120 hours using a multitester. According to the results of the research, cassava waste (liquid and onggok) can be used as a substrate in the MFC system, which has the potential to produce alternative electrical energy. Compared to salt bridges, the use of PEM in the form of chitosan-carrageenan membranes produces more significant and better electrical characteristics. However, the chitosan-carrageenan membrane is still less suitable in the long term than the salt bridge.

Research has been carried out to analyze the dynamics of the soliton DNA of the Peyrard-Bishop-Dauxois (PBD) model with 4th-order-approximation Morse Potential. The aim of research is to know physical changes of PBD model with 4th-order-approximation Morse Potential on stable and unstable state in describing denaturation process of DNA. The Process was carried out by finding a numerical solution of the 4th-order NLS as stable equation using finite-difference method. Then, the result was be simulated on Matlab. The results show that on the stable state, expand Morse Potential for 4th-order than for 3th-order rastically increased amplitude of oscillation from 1,89 pm to 16 pm. On the first unstable state, the stable equation was multiplied by (1+ ) where the value of = 0.25. On the second unstable state, the stable equation was multiplied two times by (1+ ) where the value of = 0.25. On three of them, amplitude of oscillation decreased from 16 pm, 2,9 pm to 2,5 pm. Comparing to previous order, there is a new addtion to the 4th-order Morse Potential coefficient which have physical meaning that larger expansion requires larger dissociation energy as well. So it can be concluded that the PBD model of DNA is descriptively able to explain the biological phenomenon of denaturation in DNA.

The social media with music content is currently growing very quickly, many interactions that occur are based on the same interest in content. The relationship occurs between users of the music platform based on the influence of the same interest in music that can be seen in the form of a network. This study uses the idea-based percolation method (PIB) to identify social groups based on the listener's musical genre, the Louvain method to identify group modularity, and the clique-percolation method to identify overlapping communities. The generated network includes a bipartite network that is formed when listeners are connected to a music group and a unipartite network that is formed when listeners connect with listeners who have the same musical taste. The results show that there is a network of groups based on the relationship of preferred music tastes, there are 13 communities that are formed based on the value of modularity and there are overlapping communities with 10 nodes forming a k-clique. Furthermore, the results represent that in a music network, the influence of music taste is always initiated by one user, then spreads to other users.
