Using the Situated Assessment Method (SAM²) to measure social connectedness, social support, and loneliness before and during COVID-19
Authors: Taylor Browne Lūka Courtney , Barsalou Lawrence
Published: May 2023

Increased levels of social connectedness and social support, together with decreased levels of loneliness, have been consistently linked with good mental and physical health. To better understand these constructs, it is important to measure them accurately. In previous work, we used the Situated Assessment Method (SAM²) to develop a situated psychometric instrument for measuring social connectedness and social support. The current work extended this instrument to also assess loneliness, and to assess all three constructs before and during COVID-19. As expected, we observed large individual differences, large situational variance, and large situation by individual interactions in social connectedness, social support, and loneliness. We also established underlying processes that explained high levels of variance in these constructs. Surprisingly, loneliness was unrelated to social connectedness and social support, but was explained well by underlying processes assessed with the SAM2 instrument. Interesting patterns emerged for all three constructs over the course of COVID-19.
Re-partnering and fertility
Authors: LUPPI FRANCESCA , Migheli Matteo , Pronzato Chiara
Published: May 2023

European divorce rates have been on the rise since the 1970s. At the same time, as more couples opt for cohabitation over marriage, there has been an increase in separations among cohabiting partners. Nearly 50% of separated individuals form new relationships within five years. These trends may have implications for fertility research. Are re-partnered mothers more likely to continue bearing children than never-separated mothers? Does quick re-partnering lead to the recovery of births “lost” due to separation? To answer these questions, we use longitudinal data from 2004 to 2018 for 32 European countries. We find that mothers in higher order unions are - on average – more likely to have one more child than those who already have children with their current partner. The former seem to be less burdened by already having children and less concerned about family income. Our data show that if separation occurs at a relatively young age and re-partnering occurs relatively quickly, then births lost to union dissolution can be recovered.
Delineating a ‘15-Minute City’: An Agent-based Modeling Approach to Estimate the Size of Local Communities
Authors: Chen Qingqing , Crooks Andrew
Published: May 2023

With progressively increased people living in cities, and lately the global COVID-19 outbreak, human mobility within cities has changed. Coinciding with this change, is the recent uptake of the '15-Minute City' idea in urban planning around the world. One of the hallmarks of this idea is to create a high quality of life within a city via an acceptable travel distance (i.e., 15 minutes). However, a definitive benchmark for defining a '15-Minute City' has yet to be agreed upon due to the heterogeneous character of urban morphologies worldwide. To shed light on this issue, we develop an agent-based model named 'D-FMCities' utilizing realistic street networks and points-of-interest, in this instance the borough of Queens in New York City as a test case. Through our modeling we grow diverse communities from the bottom up and estimate the size of such local communities to delineate 15-minute cities. Our findings suggest that the model could be helpful to detect the flexibility of defining the extent of a '15-minute city' and consequently support uncovering the underlying factors that may affect its various definitions and diverse sizes throughout the world.

Evaluation of Propellant/Stimgun Stimulation Works Using Geomechanical Analysis Based on Well Logging Data in an Effort to Increase Production at the EYP-211 YNK Structure Well in the Jambi Field
Authors: Priyatno Eko Yugi
Published: May 2023

The oil production flow rate of the EYP-211 well is relatively small, only 12.75 BOPD. The small fluid flow rate is caused by the small formation permeability which is only 2.1 mD. Currently the EYP-211 well has been stimulated with Propellant/Stimgun, but not all of the formation layers can be carried out by Stimgun work so that it is necessary to evaluate it with Geomechanical analysis to determine the success of the stimulation work by calculating the Poisson's ratio and Young's modulus which will be analyzed based on well-logging data.Based on the results of the brittleness index and fracability index analysis, the EYP-211 well is recommended to be stimulated at a depth of 632.92 m to 635.46 m. Stimgun work on the EYP-211 well resulted in a fracture with an average fracture width of 0.02035 in, a fracture height of 9.81 ft and a fracture length of 481.09 ft. The formation permeability increased from 2.1 mD to 14.07 mD due to fractures produced by the stimulus. The flow rate of oil production in the EYP-211 well increased from 12.75 bopd to 140 bopd due to the increased permeability generated by the fracture.

STUDI KINERJA HANDHELD PORTABLE 3D SCANNER DALAM PENGUKURAN DIAMETER DAN KEDALAMAN LUBANG PADA SPESIMEN LOGAM
Authors: Setiawan Anang Wahyu , Muslimin Muslimin , Heryana Ghany
Published: May 2023

A Handheld portable 3D Scanner is an optical-based tool that can be gripped by hand and moved from one place to another. This tool is used to scan part’s surface and produce a 3-dimensional representation in the form of a point cloud. The use of 3D Scanners has grown significantly in recent years, especially in applications in the metrology, industrial manufacturing inspection, and reverse engineering. Apart from the ease of use and flexibility of use, as an optical-based tool with triangulation principles, Handheld Portable 3D Scanners have limitations in scanning the geometric shape of a narrow hole or slit. The specifications published by the manufacturer do not fully describe tool’s performance  in this regard. For this reason, an evaluation of the performance of the Handheld Portable 3D Scanner is carried out by determining the error of measuring holes on the workpiece with variations in depth and diameter. As a reference value, the results of the Coordinate Measuring Machine –CMM measurement are used. . The study result show that handheld 3D scanners generally have an error in measuring the diameter and measuring the depth of the hole, above the specification of 0.03 mm. In holes with a diameter of 1 mm, the handheld 3D scanner has a relationship between the error of measuring hole’s diameter and hole’s diameter with the regression equation: y=0.037x-0.54. En values categorized as "outliers" were found in holes with a diameter of 1 mm with a depth of 0.5, 1, 2, 4 mm and holes with a diameter of 2mm with a depth of 4 mm.

Fresh fish is sensitive to storage temperature. Temperatures above 2 °C accelerate the growth of bacteria and cause spoilage. The optimal storage temperature for frozen fish is -20 °C. Reefer container with a closed cooling system serves to preserve by maintaining the temperature of frozen fish. The problem of this research is the uneven distribution of cold air in the reefer containers of the train, thereby reducing the quality of frozen fish. The purpose of this research is to increase the even distribution of air, velocity, and pressure in the reefer container of the train. The solution to the problem is simulation and analysis of the condition of the reefer container train using Computational Fluid Dynamics (CFD). Reefer containers without guide plates are simulated to find out the area of the train reefer containers that are not evenly distributed. The distribution of air in the reefer container of the train is improved even by the addition of guide plates with variations in angles of 40°, 50°, and 60°. This research produces qualitative data (velocity contour and pressure contour reefer container) and quantitative (average velocity and pressure). The results of this study are CFD simulation data of uniform distribution of air, speed, and pressure on the reefer container train with a 40⁰ guide plate.

Published: May 2023

The study on the role of the arbitrator in finding out the truth aims to highlight the specific elements of the arbitration procedure, considering that it must be carried out with the application and observance of the principles of the civil process dictated by the Code of Civil Procedure for all judicial procedures. The principle of finding the truth, however, has a specific applicability in private jurisdiction proceedings, given that within them a judgment in equity can take place and which differentiates them from the trial procedure before the common law courts. Finding out the truth is the goal of any judicial proceeding and leads to fair justice.

The Problem of Restrictions when taking into Account the Covid-19 Pandemic
Authors: Voroneanu-Popa R.-V.
Published: May 2023

The Covid-19 pandemic has radically changed the way people comprehend the concept of ,,fundamental right”. Without previously planning on this, we have been witnesses to an apparent ,,violation” of some rights we do not only consider to be natural, but also mandatory for any democratic society. Being worried about the effects it might have on health, state institutions have taken the decision to restrict certain liberties, be it totally, or partially. Moreover, people have had their right to circulate limited, while others could not benefit from medical services, due to the overload that has affected sanitary institutions. Given this point of view, it is mandatory to analyze the legal boundaries that have to be taken into consideration, when talking about these decisions, so that legal matters be respected, even though, there have been some limitations put in place at the moment.

Malnutrition, especially the stunting category, is a big problem for the people in Pasaman today, because it has a broad impact on aspects of life which include health, social, culture and the economy. This study aims to identify the knowledge of the people in Pasaman about fulfilling nutrition at 1000 HPK and knowing the eating patterns of the Pasaman community at 1000 HPK. This study used qualitative research methods. Data was collected through participatory observation techniques and in-depth interviews. With the number of informants as many as 35 people. The results showed that in general, the community's knowledge of fulfilling nutrition in 1,000 HPK had received counseling and socialization from the village midwife and Posyandu cadres. However, this knowledge has not been seen in the people's diet at 1,000 HPK. The practice of daily eating patterns during the 1,000 HPK era was still the same as the  habits that occurred before there was counseling. Food for pregnant and lactating women is prioritized is a matter of taste and preference, not about the nutritional content of food. Likewise with baby food 0-6 years, mothers already know that babies must be given exclusive breastfeeding, but there are still some mothers who do not give breast milk, because they think that breast milk is not filling for babies.

Published: May 2023

Background:

Detecting clinically meaningful changes in instrumental activities of daily living (IADL) at the earliest stages of Alzheimer’s disease (AD) is critical.

Objective:

The objective of this exploratory study was to examine the cross-sectional relationship between a performance-based IADL test, the Harvard Automated Phone Task (APT), and cerebral tau and amyloid burden in cognitively normal (CN) older adults.

Methods:

Seventy-seven CN participants underwent flortaucipir tau and Pittsburgh Compound B amyloid PET. IADL were assessed using the three Harvard APT tasks: prescription refill (APT-Script), health insurance company call (APT-PCP), and bank transaction (APT-Bank). Linear regression models were used to determine associations between each APT task and entorhinal cortex, inferior temporal, or precuneus tau with or without an interaction with amyloid.

Results:

Significant associations were found between APT-Bank task rate and interaction between amyloid and entorhinal cortex tau, and APT-PCP task and interactions between amyloid and inferior temporal and precuneus tau. No significant associations were found between the APT tasks and tau or amyloid alone.

Conclusion:

Our preliminary findings suggest an association between a simulated real-life IADL test and interactions of amyloid and several regions of early tau accumulation in CN older adults. However, some analyses were underpowered due to the small number of participants with elevated amyloid, and findings should be interpreted with caution. Future studies will further explore these associations cross-sectionally and longitudinally in order to determine whether the Harvard APT can serve as a reliable IADL outcome measure for preclinical AD prevention trials and ultimately in the clinic setting.
Vesicular Glutamate Transporter Changes in the Cortical Default Mode Network During the Clinical and Pathological Progression of Alzheimer’s Disease

Published: May 2023

Background:

Altered glutamatergic neurotransmission may contribute to impaired default mode network (DMN) function in Alzheimer’s disease (AD). Among the DMN hub regions, frontal cortex (FC) was suggested to undergo a glutamatergic plasticity response in prodromal AD, while the status of glutamatergic synapses in the precuneus (PreC) during clinical-neuropathological AD progression is not known.

Objective:

To quantify vesicular glutamate transporter VGluT1- and VGluT2-containing synaptic terminals in PreC and FC across clinical stages of AD.

Methods:

Unbiased sampling and quantitative confocal immunofluorescence of cortical VGluT1- and VGluT2-immunoreactive profiles and spinophilin-labeled dendritic spines were performed in cases with no cognitive impairment (NCI), mild cognitive impairment (MCI), mild-moderate AD (mAD), or moderate-severe AD (sAD).

Results:

In both regions, loss of VGluT1-positive profile density was seen in sAD compared to NCI, MCI, and mAD. VGluT1-positive profile intensity in PreC did not differ across groups, while in FC it was greater in MCI, mAD, and sAD compared to NCI. VGluT2 measures were stable in PreC while FC had greater VGluT2-positive profile density in MCI compared to sAD, but not NCI or mAD. Spinophilin measures in PreC were lower in mAD and sAD compared to NCI, while in FC they were stable across groups. Lower VGluT1 and spinophilin measures in PreC, but not FC, correlated with greater neuropathology.

Conclusion:

Frank loss of VGluT1 in advanced AD relative to NCI occurs in both DMN regions. In FC, an upregulation of VGluT1 protein content in remaining glutamatergic terminals may contribute to this region’s plasticity response in AD.

Dementia was verified in accordance with standard practice guidelines. Secondary data detailing about patient age, gender, date of dementia diagnosis and death, types of dementia, and comorbidities at the time of dementia diagnosis was obtained from electronic medical records. The association between comorbidity, patients’ underlying disease at dementia diagnosis, and overall survival were analyzed using a multivariable Cox proportional hazard model adjusted for age, gender, types of dementia, and other comorbidities.

Results:

Of the 702 patients, 56.9% were female. Alzheimer’s disease (39.6%) was the most prevalent type of dementia. Median overall survival was 6.0 years (95% CI 5.5– 6.7). The comorbidities associated with a high risk of mortality included liver disease (aHR 2.70, 95% CI 1.46– 5.00), atrial fibrillation (aHR 2.15, 95% CI 1.29– 3.58), myocardial infarction (aHR 1.55, 95% CI 1.07– 2.26), and type 2 diabetes mellitus (aHR 1.40, 95% CI 1.13– 1.74).

Conclusion:

Overall survival rate of patients with dementia in Thailand was comparable to previous studies. Several comorbidities were associated with a ten-year survival. The prognosis of patients with dementia may be improved by appropriate care of comorbidities.

Published: May 2023

Background:

We explored the gene expression levels in the brain of 3xTg-AD model mice to elucidate the molecular pathological changes from the early to end stages of Alzheimer’s disease (AD).

Objective:

We re-analyzed our previously published microarray data obtained from the hippocampus of 3xTg-AD model mice at 12 and 52 weeks of age.

Methods:

Functional annotation and network analyses of the up- and downregulated differentially expressed genes (DEGs) in mice aged 12 to 52 weeks were performed. Validation tests for gamma-aminobutyric acid (GABA)-related genes were also performed by quantitative polymerase chain reaction (qPCR).

Results:

In total, 644 DEGs were upregulated and 624 DEGs were downregulated in the hippocampus of both the 12- and 52-week-old 3xTg-AD mice. In the functional analysis of the upregulated DEGs, 330 gene ontology biological process terms, including immune response, were found, and they interacted with each other in the network analysis. In the functional analysis of the downregulated DEGs, 90 biological process terms, including several terms related to membrane potential and synapse function, were found, and they also interacted with each other in the network analysis. In the qPCR validation test, significant downregulation was seen for Gabrg3 at the ages of 12 ( p = 0.02) and 36 ( p = 0.005) weeks, Gabbr1 at the age of 52 weeks ( p = 0.001), and Gabrr2 at the age of 36 weeks ( p = 0.02).

Conclusion:

Changes in immune response and GABAergic neurotransmission may occur in the brain of 3xTg mice from the early to end stages of AD.

Background:

Study partners are required for all participants at Alzheimer’s Disease Research Centers (ADRCs). Study partners’ attitudes and beliefs may contribute to missed visits and negatively impact retention of participants in longitudinal AD studies.

Objective:

Study partners (N = 212) of participants (Clinical Dementia Rating® [CDR]≤2) at four ADRCs were randomly surveyed to examine their facilitators and barriers to continued participation in AD studies.

Methods:

Reasons for participation were analyzed with factor analysis and regression analysis. Effects of complaints and goal fulfillment on attendance were estimated with fractional logistic models. Open-ended responses were characterized with a Latent Dirichlet Allocation topic model.

Results:

Study partners participated for personal benefit and altruism. They emphasized personal benefits more when their participants had a CDR > 0 than when they had a CDR = 0. This difference declined with participant age. The majority of study partners rated their ADRC participation as positive and meeting their goals. Although half reported at least one complaint, very few regretted participating. Those who reported that ADRC participation fulfilled their goals or had fewer complaints were more likely to have perfect attendance. Study partners requested more feedback about test results and better management of study visits.

Conclusion:

Study partners are motivated by both personal and altruistic goals. The salience of each goal depends on their trust in researchers and the participant’s cognitive status and age. Retention may improve with perceived goal fulfillment and fewer complaints. Potential areas for improving retention are providing more information about the participant’s test results and better management of study visits.
Effect of Lecanemab and Donanemab in Early Alzheimer’s Disease: Mechanistic Interpretation in the Amyloid Cascade Hypothesis 2.0 Perspective
Authors: Volloch Vladimir , Rits-Volloch Sophia
Published: May 2023

In clinical trials, lecanemab and donanemab showed statistically significant yet marginal slowdown of Alzheimer’s disease (AD)-associated cognitive decline. This could be due to their sub-optimal design and/or deployment; alternatively, their limited efficiency could be intrinsic. Distinguishing between the two is of great importance considering the acute need of efficient AD therapy and tremendous resources being invested in its pursuit. The present study analyzes the mode of operation of lecanemab and donanemab within the framework of recently proposed Amyloid Cascade Hypothesis 2.0 and concludes that the second possibility is correct. It suggests that substantial improvement of the efficiency of these drugs in symptomatic AD is unlikely and proposes the alternative therapeutic strategy.
Deep learning based brain tumor detection via fuzzy hexagonal membership function
Authors: Kala R. , Deepa P.
Published: May 2023

Brain tumor is an anomalous growth of brain cells. Segmentation of brain tumors is currently the most important surgical and pharmaceutical procedure. However, manually segmenting the brain tumor is a challenging task due to the complex structure of brain. In recent years, artificial intelligence techniques with the fuzzy logic have shown better results in the field of medicine. In this work, a novel deep learning classification network with fuzzy hexagonal membership function (DLC-FHMF) model has been proposed for accurately segmenting brain tumors. The different MRI modalities namely T1, T1-c, T2 and Flair images are preprocessed using a fuzzy hexagonal trilateral and median filter to eliminate the Rician noise. Afterwards, the DLC-FHMF model is used for segmenting the tumor portion by using the multimodal composition of MRI as input. The fuzzy weights are determined with hexagonal membership functions and convoluted with the corresponding MRI images. The quantitative examination is carried out using the performance metrics namely accuracy, specificity, precision, sensitivity, incorrect segmentation, under-segmentation, and over-segmentation. In addition to the above metrics, the pre-processing metrics include PSNR, RMSE, and SSIM. The experimental fallout portrayals that the proposed DLC-FHMF approach attains a better accuracy range of 99% for detecting brain tumors using the BRATS 2013 dataset. The proposed DLC-FHMF model improves the overall accuracy by 15.1%, 11.1%, 3.0%, 21.2% and 0.5% better than ANN, SVM, NB, DNN and DAE respectively.

Published: May 2023

Data driven deep learning methods have become the mainstream method of building extraction from remote sensing images. In this paper, deep learning algorithm is used to classify and extract buildings from remote sensing images of rural areas around the Great Wall in the suburbs of Beijing captured by unmanned aerial vehicles. Aiming at the shortcomings of the current mainstream instance segmentation algorithm Mask R-CNN in feature fusion and poor prediction of instance mask boundaries, this paper proposes a boundary optimization algorithm for building instance segmentation based on discrete wavelet transform. Firstly, the discrete wavelet transform is introduced into the segmentation task branch of Mask R-CNN algorithm to extract the low-frequency and high-frequency information of the real mask, in which the high-frequency information includes the boundary information. Secondly, the pixel by pixel prediction of the mask turns into the learning of the low-frequency and high-frequency information of the real mask. The learning of the high-frequency information helps the segmentation network to learn the boundary features better. Finally, using the reversibility of discrete wavelet transform, the low-frequency and high-frequency information of the learned mask is inversely transformed to reconstruct the final mask. The improved algorithm is evaluated on the dataset COCO, and applied to the automatic extraction of buildings. The DWT Mask R-CNN algorithm model achieved 70.2% segmentation accuracy and 71.4% detection accuracy, which were improved by 1% and 0.7% respectively compared with the Mask R-CNN and Cascade Mask R-CNN models. The experimental results show that the instance segmentation edge optimization algorithm combined with wavelet transform has achieved better results on the segmentation boundary, improved the poor effect of mask edge detection and achieved higher detection accuracy, and can accurately extract village buildings.
