How Supplemental Security Income (SSI) asset caps impact access to homeownership across racial groups
Authors: Henly Megan
Published: March 2023

People with disabilities, low-income households, and Black families all
experience a substantially lower rate of homeownership in the United
States (U.S.) compared to others. A large body of literature examines
the historical and policy context for these outcomes for each of these
populations. Of note, each of these groups is substantially
overrepresented among those receiving Supplemental Security Income, or
SSI. SSI is a means-tested federal program in the U.S. that provides
monthly income to those who are blind or disabled. Recipients may not
own assets totaling more than $2,000 (or $3,000 per married couple),
excluding the value of a primary residence. For SSI recipients who do
not already own a home when they begin to receive benefits, it may be a
challenge to qualify for a mortgage. Using data from the 2019 American
Community Survey, this analysis explores the relative importance of SSI
receipt in influencing homeownership by using marginal effects to
identify the average predicted probabilities of homeownership for SSI
recipients with a disability, who are low-income, and Black. This
demonstrates the extent to which SSI asset limits impact each of these
groups differently, indicating how this policy may be a contributing
factor to the racial wealth gap.
Skin-color-independent robust assessment of capillary refill time
Authors: Bachour Raquel P. de Souza , Dias Eduardo Lopes , Cardoso George C.
Published: March 2023

Capillary Refill Time (CRT) is a visual method used to evaluate
peripheral perfusion, particularly in low-resource environments.
However, CRT’s repeatability and reproducibility are limited,
particularly for dark-skinned individuals. This paper presents
quantitative CRT measurements with good performance and repeatability
for all Fitzpatrick skin phototypes. Tests were conducted on the forearm
of 22 volunteers, using 7 kPa controlled compression, an RGB video
camera, and white LED cross-polarized light. The CRT was determined by
the time constant of an exponential regression to the green channel mean
pixel intensity. An adaptive algorithm was developed to determine the
best regression region to reduce noise, and incorrect and outlier CRT
readings were flagged from the regression uncertainties. Results showed
80% of measurements were within 20% of the expected CRT value of a
given volunteer, suggesting repeatable and reproducible quantitative CRT
methods could be developed for robust measurements in patient triage,
monitoring, and telehealth.
Leveraging Mathematical Models for Optimizing Filter Utility at Manufacturing Scale
Authors: Dhingra Ashna , Rose Steven , Joseph Adrian , Coffman Jon
Published: March 2023

In the production of biopharmaceuticals depth filters followed by
sterile filters are often employed to remove residual cell debris
present in the feed stream. In the back drop of a global pandemic,
supply chains associated with the production of biopharmaceuticals have
been constrained. These constraints have limited the available amount of
depth filters for the manufacture of biologics. This has placed
manufacturing facilities in a difficult position having to choose
between running processes with reduced number of depth filters and
risking a failed batch or the prospect of plants going into temporary
shutdown until the depth filter resources are replenished. This
communication describes a modeling based method that leverages
manufacturing scale filtration data to predict the depth filter
performance with a reduced number of filters and an increased
operational flux. This method can be used to quantify the acceptable
level of area reduction before which the filtration process performance
is affected. This enables facilities to manage their filter inventory
avoiding potential plant shutdowns and reduces the risks of negative
depth filter performance.

Published: March 2023

A previously proposed framework to model compositional grading in
continuous or semicontinuous mixtures is here extended to model
segregation profiles of reservoir-fluid columns containing heavy
fractions and asphaltenes. The gravity-induced variation in
plus-fraction molecular weights is described with a a two-moment
formulation of gravitational equilibria, to predict composition,
distribution functions and reservoir pressure gradients in
multi-ensemble fluid columns displaying gas-cap, oil leg and tar-mat
regions in the reservoir. By coupling a saturation pressure calculation
to the segregated profiles, the oil-gas and oil-tar contacts in the
reservoir are easily calculated. We first present a description of the
method for computation of these gradients. Comparison of this method
with measured data of two reservoir fluid columns shows the adequacy of
the proposed approach.

Objective To estimate the economic burden of diagnosing and
treating cervical squamous intraepithelial lesion (SIL) and cervical
cancer throughout the disease course. Design Cross-sectional
survey Setting National Population of Sample A total
of 3471 women pathologically diagnosed with SIL and cervical cancer.
Main Outcome Measures The median(IQR) of total costs (including
direct medical, direct non-medical, and indirect costs), reimbursement
rate by medical insurance, and catastrophic health expenditures in every
clinical stage of the disease were calculated. Results The
estimated total costs of LSIL and HSIL in urban areas were $1,637.7(
IQR $956.4-$2,669.2) and $2,467.1( IQR
$1,579.1-$3,762.3), while $459.0( IQR $167.7-$1,330.3) and
$1,230.5( IQR $560.6-$2,104.5) in rural areas. For patients
with cervical cancer stage IA, IB, IIA, IIB, and III-IV, the total costs
were $15,034.9( IQR $11,083.4-$21,632.4), $19,438.6(
IQR $14,060.0-$26,505.9), $22,968.8( IQR
$16,068.8-$34,615.9), $26,936.0( IQR $18,176.6-$41,386.0)
and $27,332.6( IQR $17,538.7-$44,897.0), respectively.
43%-55% of direct medical costs in cervical cancer were covered by
medical insurance, which was 19%-43% in SIL. The expense was
catastrophic for most cervical cancer patients, except for the urban
residents with stage IA. For rural cervical cancer patients, the extent
of catastrophic health expenditure was about twice larger than that for
urban residents in each cancer stage. Conclusions The total
costs of SIL and cervical cancer are substantial in China, while a large
proportion of costs are unnecessary for LSIL. As for patients with
cervical cancer, even with medical insurance, the catastrophic health
expenditures are considerable, especially for rural residents.

feedline and a box-shaped reflector. A prototype of the proposed antenna
is designed, fabricated and tested. Measured results show that the
antenna achieves an impedance bandwidth of 37.5% (0.67-0.98 GHz) for
|S11|<-15 dB, a half-power beam width (HPBW)
of 67.5±2.4 degree at H-plane (horizontal plane) and a gain of 7.9±0.4
dBi. Furthermore, the XPD is more than 15 dB at 0° and at least 11.2 dB
within ±60°at H-plane, respectively. The proposed antenna can be used in
modern communication system for LTE700/GSM850/GSM900.
A novel observer-based reinforcement learning for uncertain nonlinear systems with disturbances
Authors: Zhang Dexin , Shi Xiaoping , Song Shenmin
Published: March 2023

This study proposes an observer-based reinforcement learning(RL) control
scheme for uncertain nonlinear systems subject to various external
disturbances. The proposed approach regards the total uncertainty
estimated by the extended state observer (ESO) as potential model
information, which is incorporated into the known part of the system
dynamics. Based on the updated known dynamics, an RL structure is
constructed to approximate the optimal solution of the HJB equation
without the persistence of the excitation (PE) condition. The
convergence of the proposed policy to a neighborhood of the optimal
policy is proven, and the stability of the system states is guaranteed.
The comparative simulation results demonstrate improved performance with
a significantly reduced cost of the developed controller, and the
sensitivity of control gain in the input channel is also relaxed.
Gill proteome networks explain energy homeostasis during salinity stress in Oreochromis mossambicus
Authors: Root Larken , Kültz Dietmar
Published: March 2023

Acclimations of Oreochromis mossambicus to hypersalinity were
conducted with multiple rates of salinity increase and durations of
exposure to determine the rate-independent maximum salinity limit and
the incipient lethal salinity. Quantitative proteomics of over 3000 gill
proteins simultaneously was performed to analyze molecular phenotypes
associated with hypersalinity. For this purpose, a species- and
tissue-specific data-independent acquisition (DIA) assay library of MSMS
spectra was created. From these DIA data, protein networks representing
complex molecular phenotypes associated with salinity acclimation were
generated. O. mossambicus was determined to have a wide “zone of
resistance” from approximately 75g/kg salinity to 120g/kg, which is
tolerated for a limited period with eventual loss of organismal
function. Crossing the critical threshold salinity into the zone of
resistance corresponds with blood osmolality increasing beyond 400
mOsm/kg, significantly reduced body condition factor, and cessation of
feeding. Gill protein networks impacted by hypersalinity include
increased energy metabolism, especially upregulation of electron
transport chain proteins, and regulation of specific osmoregulatory
proteins. Cytoskeletal, cell adhesion, and extracellular matrix proteins
are enriched in networks that are sensitive to the critical salinity
threshold. Network analysis of these patterns provides deep insight into
specific mechanisms of energy homeostasis during salinity stress.
Association Between Clinical, Demographic Factors, And Substance Use Among Young Adult Survivors of Childhood Cancer

Published: March 2023

Childhood cancer survivors are at risk for late effects related to their
cancer treatment, but little is known about clinical, and demographic
associated with substance use behaviors. The purpose of this study is to
examine the associations between substance use behaviors (tobacco,
marijuana, e-cigarette, and alcohol) and cancer-related follow-up care,
treatment intensity, late effects, depressive symptoms, self-rated
health, race/ethnicity, and neighborhood socioeconomic status (nSES).
Participants were from the Project Forward cohort, a population-based
study of young adult survivors of childhood cancer. Participants
(N=1,166, Mage=25.1 years) were recruited through the Los Angeles Cancer
Surveillance Program (Cancer Registry covering Los Angeles County,
California). Multivariate path analyses were performed with substance
use as the outcome variables and clinical and demographic factors as
independent variables. Covariates included age and gender. Substance use
was positively associated with depressive symptoms, and inversely
associated with cancer-related follow-up care, female gender, age,
Hispanic ethnicity, treatment intensity, and self-rated health.
Neighborhood SES was inversely associated with tobacco use, while being
positively associated with binge drinking and e-cigarette use. The
results highlight the interrelationship among the clinical and
demographic variables and their associations with different substance
use. Findings support effective interventions targeting integrative care
and health promotion efforts for polysubstance use behavior among CCS.
This will help improve long-term outcomes and mitigate the risk for
early morbidity.
Wind- and sea-ice-driven interannual variability of Antarctic Bottom Water formation
Authors: Schmidt Christina , Morrison Adele K. , England Matthew H.
Published: March 2023

Antarctic Bottom Water (AABW) is a major component of the global
overturning circulation, originating around the Antarctic continental
margin. In recent decades AABW has both warmed and freshened, but there
is also evidence of large interannual variability. The causes of this
underlying variability are not yet fully understood, in part due to a
lack of ocean and air-sea-ice flux measurements in the region. Here, we
simulate the formation and export of AABW from 1958 to 2018 using a
global, eddying ocean–sea-ice model in which the four AABW formation
regions and transports agree reasonably well with observations. The
simulated formation and export of AABW exhibits strong interannual
variability which is not correlated between the different formation
regions. Reservoirs of very dense waters at depth in the Weddell and
Ross Seas following 1-2 years of strong surface water mass
transformation can lead to higher AABW export for up to a decade. In
Prydz Bay and at the Adélie Coast in contrast, dense water reservoirs do
not persist beyond 1 year which we attribute to the narrower shelf
extent in the East Antarctic AABW formation regions. The main factor
controlling years of high AABW formation are weaker easterly winds,
which reduce sea ice import into the AABW formation region, leaving
increased areas of open water primed for air-sea buoyancy loss and
convective overturning. Our study highlights the variability of
simulated AABW formation in all four formation regions, with potential
implications for interpreting trends in observational data using only
limited duration and coverage.
Respiration patterns in the dark ocean
Authors: Sulpis Olivier , Trossman David , Holzer Mark , Jeansson Emil , Lauvset Siv K , Middelburg Jack J
Published: March 2023

In the dark ocean, respiring organisms are the main sink for dissolved
oxygen. The respiration rate in a given seawater volume can be
quantified through dissolved oxygen drawdown or organic matter
consumption as a function of time. Estimates of dissolved oxygen
utilization rates (OUR) abound in the literature, but are typically
obtained using proxies of questionable accuracy, often with low vertical
resolution, and neglecting key regions such as the Southern and Indian
oceans. Respiration rates based on particulate (POC) or dissolved (DOC)
organic carbon are also sparsely observed and for DOC unavailable in
many regions. Consequently, the relative contributions of POC or DOC as
a respiration substrate in the dark ocean are unknown. Here we use
recent datasets of true oxygen utilization, seawater age, and DOC to
derive OUR and DOC consumption-rate profiles in 10 oceanic regions. We
demonstrate that although DOC and POC consumption rates are globally
consistent with OUR, they underestimate OUR in the deep, suggesting
strong oxygen utilization at the seafloor. In the abyss, we find a
negative correlation of DOC consumption rate with seawater age,
suggesting that DOC reactivity decreases along the deep branch of the
conveyor circulation. Our results highlight that benthic organisms are
sensitive to perturbations in the surface production of organic matter
and to large-scale circulation changes that affect its supply to the
abyss.
Uncertainty of low-degree space gravimetry observations: surface processes versus internal signal
Authors: Lecomte Hugo , Rosat Severine , Mandea Mioara , Boy Jean-Paul , Pfeffer Julia
Published: March 2023

Space gravity measurements have been mainly used to study the temporal
mass variations at the Earth’s surface and within the mantle.
Nevertheless, mass variations due to the Earth’s core might be
observable in the gravity field variations as measured by GRACE(-FO)
satellites. Earth’s core dynamical processes inferred from geomagnetic
field measurements are characterized by large-scale patterns associated
with low spherical harmonic degrees of the potential fields. To study
these processes, the use of large spatial and inter-annual temporal
filters is needed. To access gravity variations related to the Earth’s
core, surface effects must be corrected, including hydrological, oceanic
or atmospheric loading (Newtonian attraction and mass redistribution).
However, these corrections for surface processes add errors to the
estimates of the residual gravity field variations enclosing deep
Earth’s signals. As our goal is to evaluate the possibility to detect
signals of core origin embedded in the residual gravity field
variations, a quantification of the uncertainty associated with gravity
field products and geophysical models used to minimise the surface
process signatures is necessary. Here, we estimate the dispersion for
GRACE solutions as about 0.34 cm of Equivalent Water Height (EWH) or
20% of the total signal. Uncertainty for hydrological models is as

Using machine learning approach to construct the people flow tracking system for smart cities
Authors: Yao Baofeng , Liu Shijun , Wang Lei
Published: March 2023

In the crowd congestion in smart cities, the people flow statistics is necessary in public areas to reasonably control people flow. The You Only Look Once-v3 (YOLOv3) algorithm is employed for pedestrian detection, and the Smooth_L1 loss function is introduced to update the backpropagation parameters to ensure the stability of the object detection model. After the pedestrian is detected, tracking the pedestrian for a certain time is necessary to count out the specific number of pedestrians entering and leaving. Specifically, the Mean Shift algorithm is combined with the Kalman filter to track the target. When the target is lost, the Mean Shift algorithm is used for iterative tracking, and then the Kalman prediction is updated. In the experiment, 7,000 original images are collected from the library, mentioning 88 people of which 82 are recognized, and the detection accuracy reaches 93.18%. The 12,200 original images collected in the teaching building include149 people, of which 139 are recognized, with the detection accuracy reaching 93.29%. Therefore, the people flow statistics system based on machine vision and deep learning can detect and track pedestrians effectively, which is of great significance for the people flow statistics in public areas in smart cities and for the smooth development of various activities.

Background/Aim. The cause of discolored gingiva (DG) is the presence of metal in the gingival tissue. DG is a relatively common case and is caused by the deposition of amalgam material in the gingival tissue during dental application or oral surgery. The aim of this study was to determine the significance of the presence of a cast post for the appearance of DG of abutment teeth (AT) in relation to the type of alloy used to make the fixed dental prosthesis (FDP). Methods. The study included 327 subjects with FDP. A total of 1,585 AT were examined. The subjects were classified into four groups depending on the type of alloy used to fabricate their FDPs (silver-palladium, gold, nickel-chromium alloy, or a combination of them). The presence of a cast post was con-firmed by X-ray or by inspection of the dental chart. The study was conducted over the course of one year. Results. DG was observed in more than one-third (37.7%) of the sub-jects, of which 57.3% had a cast post. In the case of AT, dis-coloration occurred in 14.6%. Cast post was present in 92.7% of AT with DG. Conclusion. DG occurred in all groups of subjects regardless of the type of alloy from which the FDP was fabricated. The presence of a cast post is of great significance for the appearance of gray-bluish discoloration of the gingiva.

Published: March 2023

Background/Aim. Chronic total occlusions (CTOs) of the coronary artery are still one of the most complex procedures in the treatment of coronary arteries. If there is a bifurcation lesion within the CTO, it is certainly one of the biggest challenges for interventional cardiologists. Methods. We present a retrospective analysis of patients from our center who underwent percutaneous coronary intervention (PCI) with a bifurcation lesion within the CTO and a side branch with a diameter of 2 mm or more from January 2017 to December 2020. Results. Out of the total 216 patients in the four-year period, 38 (18%) had a bifurcation lesion within the CTO. The most common bifurcation lesions (50%) were on the left anterior descending artery, and the least frequent (21%) on the circumflex coronary artery. CTO recanalization was successful in 35 (92%) patients. The one-stent technique was used in 27 (77%) patients, while the two-stent technique was used in 8 (23%) patients. Conclusion. Bifurcation lesions in the context of PCI CTOs are a relatively common finding in coronary angiography and represent a special challenge for CTO operators. The provisional technique (one-stent technique) is the most common strategy for the treatment of bifurcation lesions in patients with CTO.

Published: March 2023

Indonesia is a country that has thousands of plant types that can be used as traditional medicine. However, some people have not utilized this potential optimally due to the lack of knowledge about medicinal plants' types, benefits, and substances. Therefore, there is a need to develop an application that can identify medicinal plants that grow in Indonesia and provide information about the benefits and content of the substances contained in them. In this study, medicinal plants will be recognized using a mobile application from leaf images based on a pre-trained convolutional neural network (CNN) with a transfer learning technique. Three pre-trained CNN architectures, namely VGG-16, MobileNetV2, and DenseNet-121, are explored for medicinal plant recognition. Hyperparameter tuning is performed at the fully connected layer of all architectures with 20 possible modifications to find the best model. The experimental results on 24 types of medicinal plants show that the model based on MobileNetV2 achieves the best classification accuracy of 97.74%. The best model is obtained by modifying the fully connected layer of MobileNetV2 into three dense layers with the number of neurons 736, 448, and 928, respectively. After the application recognizes the types of medicinal plants, information about the benefits and substances contained in them is displayed to the user.

This study was an attempt to find out the correlation among Temperature Humidity Index, milk yield, milk fat and SNF percentage at first lactation of Holstein Friesian (HF) crossbred (50% HF and 50% local) dairy cows in comparatively cooler months in the coastal areas in Bangladesh. Sixty HF crossbred cows at the early lactation stage were selected randomly from ten farms. Milk samples were collected from cows at seven days intervals and stored at 4 °C until further analysis. Data on temperature and relative humidity were collected from metrological records from late September to December 2019. The results revealed that milk yield, fat, and SNF percentage significantly differed from the THI recorded in different months. It was also observed that there was a significant (p<0.05) negative correlation between THI with milk yield, milk fat, and SNF percentage. In conclusion, the result revealed that THI greatly affects HF crossbred dairy cows' milk yield and composition in comparatively cooler months.

In developing countries, a large proportion of patients with scoliosis present late, especially the underprivilege, so the curves had become rigid and severe. There is still no consensus about the surgical management of the severe and rigid scoliosis and some literatures suggested that combined anterior and posterior or single-stage posterior-only instrumentation are generally required for the correction of these deformities. We presented three cases of severe rigid scoliosis treated surgically in our center with two staged operation (anterior surgery and posterior instrumentation). A retrospective review was undertaken of patients with severe scoliosis who had undergone two-staged operation in Orthopaedics and Traumatology Department of Prof Ngoerah General Hospital Bali during the period between January 2018 and February 2020. The data was obtained from the hospital’s medical records and archives in our department, included sex, age, the severity and reducibility of the Cobb angle, maturity rate, treatment, length of stay, complications found, and the Scoliosis Research Society: 30 Questionnaire (SRS-30) score before and three months after the surgery. During the period of between January 2018 and February 2020, there were three cases of severe rigid scoliosis who underwent two-staged operation. The two staged operation performed were anterior surgery (soft tissue release, corpectomy, and anterior fusion), and posterior instrumentation (facetetectomy, rotation, stabilization, and fusion). There were one case of intra-operative hypovolemic shock and anemia that could be corrected succesfully. All three patients showed no complaint and the clinical examination showed improvements of the deformity post operatively. There were also improvement of the total SRS-30 score of all three patients after the two staged procedures performed (mean = 4.4) compared to pre-operative score (mean = 3.4). The two-staged operation including anterior surgery and posterior instrumentation is still a safe and effective way in treatment of severe rigid scoliosis.
MEN’S SEXUAL TRAUMA RESISTANCE IN BLACK AMERICAN FOLKLORE: A POSTCOLONIAL CRITICISM OF NEGRO “WOMAN TALES”
Authors: Ntamwana Simon
Published: March 2023

The purpose of this paper “Men’s Sexual Trauma Resistance in Black American Folklore: A Postcolonial Criticism of Negro “Woman Tales” from the Gulf States” was to discuss the reflection of postcolonial sexual trauma and resistance to it through storytelling among African Americans in the Gulf States. The study was concerned with 3 folktales classified under the cycle “Woman Tales”. The folktales were selected from the collection made by Zora Neale Hurston in the southern states of Alabama, Florida, and Louisiana from 1927 to 1930 and compiled in the book Every Tongue Got to confess: Negro Folktales from the Gulf States (2001). The postcolonial approach and trauma theory based on the interpretative qualitative method and library research was used in the discussion of the selected folktales. It was found that the performance of the “Woman Tales” is informed by the black men’s traumatic memories of slavery and post-slavery emasculation. Black male narrators imitate trauma narratives in which they reflect male sexual trauma and recreate black woman identity to contain it. Through this imitation and reflection, the folktales challenge the legacy of the plantation patriarchy by reconstructing a woman's identity that is docile to black masculinity.

Technological versatility and the humoral and cellular immune response induction capacity have conditioned wide spread of adenoviral vectors as vaccine and gene therapy drugs. However, vaccination with Sputnik V made a significant portion of the population immune to the types 5 and 26 (Ad5 and Ad26) recombinant human adenovirus vectors, which are some of the most frequently used bases for candidate vaccines. Today, vaccine designers tend to select alternative adenovirus serotypes as platforms to develop vaccines against new pathogens on. A good example is simian adenovirus type 25 (SAd25), which belongs to subgroup E. It is genetically distant from Ad5 and exhibits extremely low seroprevalence in human beings, which makes it an appealing alternative vaccine vector. The purpose of this work was to design and study a new vaccine platform based on simian adenovirus type 25. We relied on the advanced methods of molecular biology and virology to construct and make recombinant adenoviruses; the phylogenetic analysis in the context of this study was enabled with bioinformatic methods. The resulting recombinant adenoviral vector can effectively replicate itself in the HEK293 cell line (human embryonic kidney cells). This work substantiates the expediency of further investigation into the SAd25 vector as a platform for development of the prevention vaccines against various infectious diseases.
Integration of Bibliotherapy Techniques and Spiritual Guidance as A Mental Strengthening Strategy in Post-Psychosis Patient Rehabilitation Dynamics
Authors: Nida Fatma Laili Khoirun
Published: March 2023

One mental health problem that is often overlooked is related to patient survival after undergoing psychosis treatment. The post-psychotic patient group is a group that is vulnerable to receiving bad treatment from society as a result of their experiences while suffering from mental disorders. Stigmatization and marginalization are forms of bad attitude that post-psychotic patients often receive when they return to society which triggers the failure of the mental treatment process they have been through. For this reason, mental strengthening is needed for psychosis patients as part of preventive efforts to prevent recurrence and re-treatment. This study aims to determine the strategies used in the process of strengthening the mentality of post-psychotic patients when they are undergoing the rehabilitation process before discharge. This study used a qualitative method with data collection techniques through observation, interviews and documentation conducted at the Jalma Sehat Mental Rehabilitation Center, Kudus Regency as the research location. The results of the study explained that the mental strengthening was carried out by therapists at the study sites by integrating biblitherapy techniques in the form of creation and innovation of wisdom stories which were integrated with spiritual guidance during the rehabilitation process before discharge. The interventions provided have an impact on the mental readiness of post-psychotic patients to face all the worst possibilities they receive when they return to society. This research is one of the contributions in the development of concepts and practices in psychotherapy for psychosis patients, especially in the study of rehabilitation after psychosis treatment.
