COMMUNITY WATER FLUORIDATION A COST-BENEFIT-RISK CONSIDERATION
Authors: Osmunson Bill , Cole Griffin
Published: May 2024

Background For over 70 years the addition of fluoride to public
water with intent to prevent dental caries continues to be controversial
and risks are seldom included in monetary evaluations.
Objectives To estimate an economic cost-benefit-risk of
Community Water Fluoridation (CWF) using 2021 USA dollars Per Person Per
Year (PPPY), with the inclusion of two risks: dental fluorosis and lower
income resulting from developmental neurotoxicity as measured with lower
IQ. Methods Published operational costs and benefits of CWF are
used. Published and clinical experience treating dental fluorosis are
utilized to estimate treatment costs of patient perceived dental
fluorosis, and lost wages from lower IQ. Patients of record provided
consent for photographs. Results: Published estimated caries
averted, less operational costs, were calculated at $8 PPPY and
estimates of compensation for functional and cosmetic dental fluorosis
were $126 PPPY. Lower earnings from presumed harm of developmental
neurotoxicity $438 PPPY. Net loss from CWF is estimated at $556 PPPY.
Conclusions Previous economic evaluations of CWF have estimated
caries averted and costs of operations. Few evaluations include the
costs of treating harm. CWF is not cost effective if the cost of harm is
included. Policy Implications Alternatives for the prevention
of dental caries should be promoted and the cessation of CWF is
indicated.

The geographical distribution and diversity of viruses can differ
between cultivated areas and adjacent natural environments, raising
questions about the interplay between plant diversity and the species
richness and prevalence of the phytoviruses. As both the amplification
and the dilution of viral species richness due to increasing host
diversity have been theorized and observed, a deeper understanding of
how plant-viruses interact in natural environments is needed to explore
how host availability conditions viral diversity and distributions. This
study explores interactions of viruses from the Mastrevirus genus
(family Geminiviridae) with hosts from the Poaceae family across ten
sites from three contrasting ecosystems on La Réunion. Among 273 plant
pools, representing 61 Poales species, 15 Mastrevirus species were
characterized from 22 hosts. We find a strong association of
mastreviruses with hosts from agro-ecosystems and the absence of
mastreviruses in subalpine areas, dominated by native plants. This
suggests that all detected mastreviruses likely originated from viruses
introduced through agricultural activities rather than being native to
La Réunion. Analyses of the structure of the host plant-mastrevirus
interaction network revealed a pattern of increasing viral richness with
increasing host richness. Accounting for variations in the diversity of
hosts across sites, we observed increasing viral niche occupancies with
increasing host species richness. Virus realized richness at any given
site is conditioned on the global capacity of the plant populations to
host diverse mastreviruses. Whether this tendency is driven by synergy
between viruses, or by an interplay between vector population and plant
richness, remains to be established.
When and Where does Irrigation Water Originate? Leveraging Stable Water Isotopes and Synthetic Aperture Radar to Assess the Complex Hydrology of a Snow-Dominated Catchment in Southwestern Montana

Published: May 2024

Many agricultural regions around the world rely on melt from mountainous
snowpacks for irrigation. As climate change-induced snow droughts
intensify, water resource managers will need more efficient and accurate
methods to characterize the snowmelt cycle and forecast water
availability. Here, we integrate in-situ and remotely-sensed data to
assess the relative contributions of groundwater and the current
season’s snowmelt to irrigation water supply for water year 2023 (WY,
Oct 1 – Sep 30) for a montane headwater catchment in southwestern
Montana (423 km , elevation ranges between 1465 m and
3270 m). We analyze Sentinel-1 Synthetic Aperture Radar (SAR) data to
approximate dates of snowmelt runoff onset at 10 m resolution every
twelve days. We find that the watershed’s median date of snowmelt runoff
onset in WY 2023 was April 20. To assess relative contributions to
streamflow, we compare stable water isotope ratios (δH
, δO ) from biweekly stream water
samples at low elevations against monthly samples of snow and
groundwater. We find that stream water below the highest diversion point
is predominantly composed of groundwater. The maximum contribution from
snowmelt was measured in May at 22%. Results demonstrate alignment
between two disparate approaches for estimating snowpack contribution to
stream flow. While our work focuses on a catchment in Montana, the
approaches used are potentially applicable globally for agricultural
regions that rely on snowmelt for irrigation, particularly in poorly
instrumented areas.

Published: May 2024

In the surge of the digital era, the Metaverse, as a groundbreaking
concept, has become a focal point in the technology sector. It is
reshaping human work and life patterns, carving out a new realm of
virtual and real interaction. However, the rapid development of the
Metaverse brings along novel challenges in security and privacy. In this
multifaceted and complex technological environment, data protection is
of paramount importance. The innovative capabilities of high-end devices
and functions in the Metaverse, owing to advanced integrated circuit
technology, face unique threats from Side-Channel Analysis (SCA),
potentially leading to breaches in user privacy. Addressing the issue of
domain differences caused by different hardware devices, which impact
the generalizability of the analysis model and the accuracy of analysis,
this paper proposes a strategy of Portability Power Profiling Analysis
(PPPA). Combining domain adaptation and deep learning techniques, it
models and calibrates the domain differences between the profiling and
target devices, enhancing the model’s adaptability in different device
environments. Experiments show that our method can recover the correct
key with as few as 389 power traces, effectively recovering keys across
different devices. This paper underscores the effectiveness of
cross-device SCA, focusing on the adaptability and robustness of
analysis models in different hardware environments, thereby enhancing
the security of user data privacy in the Metaverse environment.

Published: May 2024

Stem cells have differentiation and regulatory functions. Here, we
discuss the effect of cell culture density on stem cell proliferate,
adipogenesis and regulation ability. To investigate the effect of the
initial culture density of human periodontal ligament stem cells
(hPDLSC) on the adipogenic differentiation of autologous cells. We found
that the proliferation rate of hPDLSC increased with the initial cell
densities (0.5~8 × 10 cells/cm
) increase. After adipogenic differentiation induced
by different initial cell densities of hPDLSC, we found that the mean
adipose concentration and the expression levels of lipoprotein lipase
(LPL), CCAAT/enhancer binding protein α (CEBP-α) and peroxisome
proliferator-activated receptor γ (PPAR-γ) genes all increased with
increasing cell density. To investigate the regulatory role of hPDLSCs
on the adipogenic differentiation of other cells, we used secreted
exosomes derived from hPDLSCs cultured at different initial cell
densities of 50 μg/mL to induce the adipogenic differentiation of human
bone marrow stromal cells (hBMSC). We also found that the mean adipose
concentration and the expression of LPL, CEBP-α and PPARγ genes
increased with increasing cell density, the optimal culture density was
8 × 10 cells/cm . This provides a
laboratory research basis for the application of adipogenic
differentiation of stem cells.
An ultra-wideband low noise Colpitts VCO using SiGe BiCMOS technology
Authors: Cai Peiying , Peng Tao , Su Boming , Wu Yi , Huang Guochi
Published: May 2024

An ultra-wideband Voltage-Controlled Oscillator based on the Colpitts
structure is proposed in this work. The entire circuit consists of four
Colpitts VCO cores operating at different frequency. Every VCO core
employs two single-ended Colpitts oscillators arranged back-to-back and
sharing a common LC resonating tank. The coupling coefficient between
the two single-ended Colpitts oscillators is increased by introducing a
transformer placed on the emitter node of the core transistor, which
ensures two Colpitts oscillators oscillating in a differential mode.
Furthermore, a series of amplifier circuits, including a fundamental
frequency amplifier, second harmonic amplifier, and frequency
multiplier, are employed to amplify the second harmonic signal and
convert it into a differential signal, thereby expanding the operating
bandwidth of the oscillator. The fundamental frequency of the proposed
Colpitts VCO ranges from 3.5 GHz to 7GHz, and the frequency can reach up
to 14GHz or 28GHz by generating second or fourth harmonics. The measured
phase noise performance is lower than -130dBc/Hz, -124dBc/Hz and
-118dBc/Hz at 1MHz offset across the entire frequency range. The power
dissipation of the entire VCO is typically around 60mW under 3.3V power
supply.

Published: May 2024

Zirconia implants have emerged as a promising novel material in the
field of dentistry due to their ability to overcome certain limitations
associated with titanium implants. However, the appropriate
sterilization protocols for zirconia implants have not yet been
thoroughly investigated. To address this gap, this study conducted an
assessment of the surface characteristics of fully sintered 3Y-TZP
zirconia slices after being subjected to various sterilization methods,
including ethylene oxide (EO), hydrogen peroxide plasma (HPP), electron
beam (EB), and a combination of hydrogen peroxide plasma with either
ethylene oxide (HPP+EO) or electron beam treatment (HPP+EB). Although
the HPP treatment group did not demonstrate the highest level of
hydrophilicity and contamination removal, it did exhibit notable
hydrophilicity, effectively prevented hydrocarbon contamination, and
maintained a substantial concentration of Zr. The surface of zirconia
treated with HPP displayed significant enhancements in cell
proliferation, cytoskeleton development, osteogenic differentiation, and
adhesion capabilities for hBMSCs and HGFs, surpassing the performance of
other groups. Based on these findings, the sterilization of zirconia
implants using hydrogen peroxide plasma therapy appears to be a feasible
technique.
Transient Frequency Response Test and Measurement Error Prediction of DCTV based on AI
Authors: Yang Yutao , Zhai Shaolei , Tang Hansong , Duan Genyue , Deng Liwu
Published: May 2024

To solve the problem that the Frequency Response (FR) test scheme and
equipment of the traditional DC Voltage transformer (DCTV) used for DC
transmission are insufficient, and the Measurement Error (M-E) of the
related measurement system is difficult to achieve accurate prediction,
a temporary FR test and M-E prediction method of DCTV based on
Artificial Intelligence (AI) is proposed. Firstly, the frequency
characteristic of DC side voltage of DCTV is analyzed. On this basis, a
DCTV transient FR testing method based on transient AC & DC
superposition was developed. Then, the method of voltage sudden change
and phase correction is used to achieve transient process DCTV response
time testing. Finally, the Ant Colony Optimization (ACO) algorithm was
improved by combining an adaptive inertia weight improvement strategy,
achieving accurate prediction of the M-E of DCTV. The proposed AI based
DCTV transient FR testing and M-E prediction method were compared and
analyzed with the other three methods through simulation experiments.
The results indicate that under the same experimental conditions, the
prediction results of the DCTV measurement ratio error and phase angle
error of the proposed method are optimal.

Published: May 2024

Bovine mastitis is characterized by pathological alterations of the
mammary tissue and physical and chemical changes in the milk causing
large economic losses in the dairy industry. The most common etiological
agents include a variety of bacteria that may be either contagious or
environmental. Furthermore, antibiotic treatment has lost effectiveness,
leading to residues in milk and activation of resistance mechanisms in
bacteria. Therefore, improving the knowledge about the variety,
prevalence, and antimicrobial susceptibility of mastitis-causing
bacteria may assist in the development of new strategies to optimize
mastitis control. This study aimed to characterize bacterial species
causing mastitis from geographically related dairy plants in southern
Chile. To do this, milk samples obtained from milking cows diagnosed
with clinical mastitis (n=50) and from apparently healthy animals (n=25)
were cultured for microbiological characterization, including species
identification and antibiotic susceptibility. Morphological
identification and Gram staining showed Gram (+) cocci, Gram (-)
bacilli, and Gram (+) bacilli. A large diversity of bacteria was
detected in both mastitis and non-mastitis samples. The most frequently
isolated species were Corynebacterium spp., Staphylococcus haemoliticus,
and Staphylococcus aureus. Besides, Staphylococcus haemoliticus and
Escherichia coli showed complete resistance and intermediate antibiotic
resistance, respectively. Conclusions: the most prevalent variety of
bacterial species associated with mastitis in southern Chile are
coagulase-negative staphylococci. Furthermore, sampling the entire herd,
provides a broader view of the etiological agents causing bovine
mastitis. The results of the present study provide an update regarding
etiological agents and sampling management of bovine mastitis in
southern Chile.
Genetic rescue leads to higher fitness as a result of increased heterozygosity across animal taxa
Authors: Clarke Julia , Smith Adam , Cullingham Catherine
Published: May 2024

Biodiversity loss has reached critical levels due in part to
anthropogenic habitat loss and degradation. These landscape changes are
particularly damaging as they can result in fragmenting species
distributions into small and isolated populations, resulting in limited
gene flow, population declines and reduced adaptive potential. Genetic
rescue, the translocation of individuals for the purpose of restoring
gene flow, has been shown to produce promising results for fragmented
populations but remains relatively under-used due to a lack of long-term
data and monitoring of genetic rescue attempts. To promote a better
understanding of genetic rescue and its potential risks and benefits
over the short-term, we reviewed and analyzed all genetic rescue
attempts to date to identify whether genetic diversity increases
following rescue, and if this change is associated with increased
fitness. Our review identified only 19 genetic rescue studies, that
included experimental, natural, and conservation motivated, with the
majority of studies being on mammals. We used a Bayesian meta-analytical
approach to examine the relationship between fitness and genetic
diversity. We found that genetic diversity, as represented by
heterozygosity, was a positive predictor of population fitness, and this
relationship extended to the third-generation post-rescue. These data
suggest a single introduction can have lasting fitness benefits,
supporting translocation as another tool to ensure conservation success.
Given the limited number of studies with long-term data, we echo the
need for genetic monitoring of translocations to ascertain whether
genetic rescue may also limit the loss of adaptive potential in the
long-term.
An Unusual Mass originates from the anterior tricuspid leaflet in an adult patient: Blood-Filled Cyst

Published: May 2024

Blood-filled cysts (BFCs) are considered benign and often asymptomatic,
most originate from congenital. However, BFCs of the heart valves are
common at autopsy in infants but rare in adults. We report the case of
an adult female who presented with a solitary complaint of chest
distress on exertion, which led to the discovery of an intracardiac
cystic mass on the anterior tricuspid leaflet. A single surgical
intervention was sufficient to remove the resected cystic mass. Our case
is the first to report a highly unusual blood-filled cyst on the
anterior tricuspid leaflet in an adult.
On m-point homogeneous polytopes in euclidean spaces

Published: May 2024

This paper is devoted to the study the m-point homogeneity property and the
point homogeneity degree for finite metric spaces. Since the vertex sets of
regular polytopes, as well as of some their generalizations, are
homogeneous, we pay much attention to the study of the homogeneity
properties of the vertex sets of polytopes in Euclidean spaces. Among main
results, there is a classification of polyhedra with all edges of equal
length and with 2-point homogeneous vertex sets. In addition, a significant
part of the paper is devoted to the development of methods and tools for
studying the relevant objects.

Almost Kähler structures on complex hyperbolic space
Authors: Dekic Andrijana
Published: May 2024

Complex hyperbolic space has the structure of a solvable Lie group. Based on
the recent classification of Riemannian left-invariant metrics we describe
all left-invariant almost K?hler structures on that group. The only K?hler
structure is the standard structure of the complex hyperbolic space and all
others are strictly almost K?hler. We calculated the Chern connection and
obtained the characterization by its torsion tensor. It is proved that the
only SCF-soliton is the K?hler one.

Recently, a generalized almost Hermitian metric on an almost complex manifold
(M, J) is determined as a generalized Riemannian metric (i.e. an arbitrary
bilinear form) G which satisfies G(JX, JY) = G(X,Y), where X and Y are
arbitrary vector fields on M. In the same manner we can study a generalized
almost para-Hermitian metric and determine almost para-Hermitian spaces.
Some properties of these spaces and special generalized almost
para-Hermitian spaces including generalized para-Hermitian spaces as well as
generalized nearly para-K?hler spaces are determined. Finally, a
non-trivial example of generalized almost para-Hermitian space is
constructed.
