Soybean Collect Recommender Based on Distance and Productivity Cluster Using K-means Clustering and Simple Addictive Weighting Method
Authors: Ningtyas Mega Wahyu , Pribadi Feddy Setio
Published: August 2023

Soybeans are an essential agricultural product that is one of the primary food sources in Indonesia, such as tempeh, tofu, soy milk, soy sauce, and other preparations. However, production yields, harvested land area, and soybean productivity in each district or city in Central Java Province vary widely. Differences in soybean productivity in each area are due to production factors such as area, use of fertilizers, seeds, and labor. This study tries to provide recommendations for soybean harvesting based on the distance and productivity of an area using K-means clustering and the simple addictive weighting method. In the Central Java Province, 35 regions will be divided into four clusters: the first with high productivity, the second with medium productivity; the third with low productivity; and the fourth with very low productivity. Additionally, based on the fourth cluster clustering results, it will be advised to take soybeans from other clusters by taking the closest distance and cluster members into account. According to the research, four clusters have formed: the first has five members, the second has fourteen, the third has nine, and the fourth has seven. The fourth cluster, which consists of seven members who do not grow soybeans, is advised to buy soybeans from the following regions: Kendal Regency, Klaten Regency, Magelang Regency, Batang Regency, and Brebes Regency.
Comparison of DC Motor Speed Calculation Efficiency between Inductive Proximity Sensor and Rotary Encoder
Authors: Aryanto Dino Dwi , Sukir S.
Published: August 2023

This study examines the level of effectiveness and efficiency of a sensor on the calculation of the rotational speed (RPM) of a DC motor, considering that the calculation of the rotational speed of an electric motor, both AC motors and DC motors, greatly influences the output of the system. the speed of motor rotation is very influential in several fields, such as power generation, which will affect the output voltage that will be generated. There are many methods for measuring the rotational speed of a motor, including using an inductive proximity sensor and a rotary encoder combined with a PLC as a control center and data processor so that the rotational speed can be read. the output of the proximity sensor and rotary encoder will be connected to the PLC input pin so that data will appear in the form of a pulse value which can be seen in the program that has been made. The data obtained will be processed in a program that uses special instructions, namely PRV. In comparison, the speed of a dc motor will be changed using a PWM module or pulse width modulation to adjust the rotational speed of the motor. From the results of experiments that have been carried out using the proximity sensor, it gives an average motor speed reading of 6420 Rpm with an error of -10.3, and experiments carried out using a rotary encoder give an average motor speed reading of 6409.3 Rpm with an error of 0.4 so that it can be concluded that the use of a rotary encoder is more accurate than the use of a proximity sensor to calculate motor speed.
Social Support–Seeking Strategies on Social Media at the Intersection of Lesbian, Gay, Bisexual, Transgender, and Queer Identity, Race, and Ethnicity: Insights for Intervention From a Qualitative Study (Preprint)
Authors: Gordon Jacob D , Whitfield Darren L , Mammadli Tural , Escobar-Viera César G
Published: August 2023

BACKGROUND

Lesbian, gay, bisexual, transgender, and queer (LGBTQ+) individuals experience a disproportionately higher prevalence of mental health challenges when compared to their heterosexual and cisgender counterparts. Moreover, they exhibit increased engagement with social media platforms relative to their peers. Understanding the intersectional dynamics of their identities is crucial in elucidating effective and safe approaches to garnering social support through social media channels. This exploration holds significance for informing future research endeavors and shaping targeted interventions to address the unique mental health needs of LGBTQ+ individuals.

OBJECTIVE

The purpose of this study was to explore the strategies used by Black, Hispanic, and non-Hispanic White LGBTQ+ young adults to acquire social support from social media. The study aimed to examine how these strategies may differ by race and ethnicity.

METHODS

We conducted semistructured interviews with LGBTQ+ young adults aged between 18 and 30 years recruited in the United States from social media. Of 52 participants, 12 (23%) were Black, 12 (23%) were Hispanic, and 28 (54%) were non-Hispanic White. Thematic analysis was used to analyze the collected data.

RESULTS

The analysis uncovered both divergent and convergent strategies among participants of different races and ethnicities. Black and Hispanic young adults exhibited a preference for connecting with individuals who shared similar identities, seeking safety and tailored advice. Conversely, non-Hispanic White participants demonstrated minimal preference for identity-based advice. Seeking support from anonymous sources emerged as a strategy to avoid unwanted disclosure among Hispanic participants. Furthermore, all participants emphasized the importance of content filtering with family members to cultivate positive and supportive social media experiences.

CONCLUSIONS

This study sheds light on the strategies used by LGBTQ+ individuals of different racial and ethnic backgrounds to seek social support from social media platforms. The findings underscore the importance of considering race and ethnicity when examining social support–seeking behaviors on social media in LGBTQ+ populations. The identified strategies provide valuable insights for the development of interventions that aim to leverage social support from social media to benefit the mental health of Black, Hispanic, and non-Hispanic White LGBTQ+ young adults.
PULL-DOWN INSTABILITY OF THE QUADRATIC NONLINEAR OSCILLATORS
Authors: He Ji-Huan , Yang Qian , He Chun-Hui , Alsolami Abdulrahman Ali
Published: August 2023

A nonlinear vibration system, over a span of convincing periodic motion, might break out abruptly a catastrophic instability, but the lack of a theoretical tool has obscured the prediction of the outbreak. This paper deploys the amplitude-frequency formulation for nonlinear oscillators to reveal the critically important mechanism of the pseudo-periodic motion, and finds the quadratic nonlinear force contributes to the pull-down phenomenon in each cycle of the periodic motion, when the force reaches a threshold value, the pull-down instability occurs. A criterion for prediction of the pull-down instability is proposed and verified numerically.
Neglected ecological and health risks associated with the use of diclofenac in veterinary medicine: A mini-review
Authors: Gutiérrez Lilia , Alcalá Canto Yazmín , Alberti-Navarro Aldo B. , Carrillo González Lizbeth , Sumano López Héctor
Published: August 2023

There is sufficient scientific evidence to support that residues of diclofenac, a non-steroidal anti-inflammatory drug (NSAID) administered to livestock raised in the open, can cause fatal renal crystallization in vultures' species, and perhaps other birds such as eagles, if treated animals enter the trophic chain. This phenomenon caused the population of vultures to decline sharply, on the brink of extinction, in India, Pakistan, Tibet, and many countries in the Middle East. For this reason, except for Spain, this medication has been prohibited for veterinary use in the rest of Europe, the United States of America, Canada, Japan, Australia, New Zealand, and many other countries. In contrast, in Latin America, diclofenac is available for veterinary use in various preparations alone or combined with antibacterial drugs. The precise impact this is generating on the native species of vultures and other birds that feed on animals that die in open pastures and are not incinerated is unknown. Given the nature of our livestock production via small producers and extensive farming, most animals medicated with this NSAID can enter the natural food chain and become part of the vulture diet. Most researchers who have studied this ecological problem have recommended that countries adhere to the precautionary principle of prohibiting its sale until there is concrete evidence of the magnitude of the damage that the permissive use of diclofenac in veterinary medicine may cause in Latin America. In Mexico, the official standard NOM-064-ZOO-2000, Lineamientos para la clasificación y prescripción de los productos farmacéuticos veterinarios por el nivel de riesgo de sus ingredientes activos, recommends incinerating animals treated with diclofenac, a command that does not fit our daily reality. The question is: shall Latin American countries remain inactive despite a hitherto invisible ecological disaster? Research in Latin America needs to be carried out that supports or rejects the possible impact of diclofenac on wild species, including vultures. However, many countries on the continent, including Mexico, have adhered to the 11th Declaration of Rio for Sustainable Development in the 21st century. Based on this, we propose that action should be taken without delay to avoid or limit an ecological disaster by banning diclofenac in veterinary medicine.

Optimizing sparse fermionic Hamiltonians
Authors: Herasymenko Yaroslav , Stroeks Maarten , Helsen Jonas , Terhal Barbara
Published: August 2023

We consider the problem of approximating the ground state energy of a fermionic Hamiltonian using a Gaussian state. In sharp contrast to the dense case [1, 2], we prove that strictly q-local sparse fermionic Hamiltonians have a constant Gaussian approximation ratio; the result holds for any connectivity and interaction strengths. Sparsity means that each fermion participates in a bounded number of interactions, and strictly q-local means that each term involves exactly q fermionic (Majorana) operators. We extend our proof to give a constant Gaussian approximation ratio for sparse fermionic Hamiltonians with both quartic and quadratic terms. With additional work, we also prove a constant Gaussian approximation ratio for the so-called sparse SYK model with strictly 4-local interactions (sparse SYK-4 model). In each setting we show that the Gaussian state can be efficiently determined. Finally, we prove that the O(n−1/2) Gaussian approximation ratio for the normal (dense) SYK-4 model extends to SYK-q for even q>4, with an approximation ratio of O(n1/2–q/4). Our results identify non-sparseness as the prime reason that the SYK-4 model can fail to have a constant approximation ratio [1, 2].

Este libro surge como resultado de la investigación doctoral “La lucha campesina como forma de vida. Colombia 1850-2015”, realizada por Andrea Cely Forero. En ella se concluye que, desde una mirada de largo plazo, es necesario reconocer que la lucha campesina no sería posible sin los esfuerzos llevados a cabo desde el hogar, las organizaciones campesinas y las protestas. Son estas tres prácticas las que permiten subvertir la relación con los hacendados, defender la economía campesina, sostener durante semanas distintos tipos de protesta y mantener activas estructuras organizativas. El rol de las mujeres se presenta como una constante definitiva para garantizar la reproducción material del campesinado. Las mujeres campesinas han sido quienes se han encargado de asegurar la alimentación, el cuidado y la administración de ingresos adicionales en las familias. Además de realizar el trabajo doméstico, cuidar de sus hijos, preparar los alimentos y garantizar la reproducción de la fuerza de trabajo, también generaron una dinámica productiva alrededor de la economía campesina que brindó a sus familias la independencia económica. Este hecho fue determinante para provocar una idea de libertad con respecto al sistema de hacienda a partir de la reivindicación de la economía campesina que se mantiene hasta la actualidad. Las fincas son un espacio fundamental para la reproducción material de la estructura organizativa e incluso para sostener una protesta de varios días de duración. De esta manera, este libro busca rendirles tributo al rol de las mujeres, a la identidad campesina y a la vida de niñas y niños que, como cualquiera de nosotros, aprenden en su cotidianidad.

Published: August 2023

Polycyclic N-heterocycles are very important scaffolds in biomedicinal
chemistry and materials science. Intramolecular alkyne hy-droamination
is a powerful method for the construction of N-heterocycles. In the last
two decades, copper-catalyzed domino reac-tions based on intramolecular
alkyne hydroamination has emerged as a robust strategy for assembling
various polycyclic N-heterocycles. Great progress has been achieved in
this area. This short review covers the advances made in
copper-catalyzed domino synthesis of polycyclic N-heterocycles based on
this strategy from 2008 to 2023, and will hopefully serve as an
inspiration towards the exploration of new copper-catalyzed versions of
the transformation. The domino transformations are introduced and
discussed from five aspects according to the different key processes
involved in these reactions.

Published: August 2023

[Conventional
tillage](https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/conventional-tillage)
is still widely used in mollisols sloping farmland, which leads to
serious [soil
erosion](https://www.sciencedirect.com/topics/earth-and-planetary-sciences/soil-erosion)
. Effective farming methods have positive significance for alleviating
soil erosion .To prevent and control soil and water loss in mollisols
sloping farmland,field experiments were carried out in 2022 with three
tillage methods and their combination modes(Subsoiling tillage
(SF),Ridge tillage and pitting field (RF),Ridge tillage and pitting
field + subsoiling tillage (RF-S),Contour tillage (TP),Contour tillage +
ridge tillage and pitting field (TP-R),Contour tillage + subsoiling
tillage (TP-S)) to evaluate the effects of soil and water conservation
under different tillage methods. The results showed that the contour
tillage + ridge field treatment significantly reduced surface runoff and
soil loss ( P < 0.05), and there was no nutrient loss.
Compared with other treatments, this method significantly reduced
runoff, erosion, and nutrient loss. The contour tillage + subsoiling
tillage treatment significantly reduced the soil three-phase R value and
improved the soil texture, and its yield, harvest index, and water use
efficiency were higher than those of other treatments. Considered
comprehensively, the results show that contour tillage + subsoiling
tillage can reduce soil erosion and improve soil quality and water use
efficiency while ensuring high production capacity. Furthermore, the
results of this study provide a theoretical basis for conserving soil
and water resources, improving soil fertility, and increasing farmland
yield in the mollisols area of northeast China.

Aims: The aim of this study was to examine the effects of
sericin on diabetic cognitive impairment (DCI) in rats based on
neuroinflammation. Methods: SD rats were firstly fed with high
sugar and high fat diet for 4 weeks, and then injected with 50 mg/kg
streptozotocin intraperitoneally to establish a diabetic model. The
diabetic rats were randomly divided into 3 groups and treated with
distilled water (n=10), 500 mg/kg (n =10) and 1000 mg/kg (n=20) sericin,
respectively, by gavage once a day for 8 weeks. Before the end of the
trail, 10 rats in the 1000 mg/kg sericin group were injected with 10 μg
EX527 (a SIRT1 inhibitor) into the lateral ventricles once every other
day for 5 times. Results: Treated with sericin significantly
reduced the fasting blood glucose, improved DCI in rats. Sericin
significantly inhibited of neuroinflammation, reduced the expression of
NLRP3, TXNIP proteins and reduced cell apoptosis, while increased the
expression of SIRT1 protein in the hippocampus of diabetic rats. After
inhibiting SIRT1 with EX527, the above effect of sericin on DCI rats was
weakened. Conclusions: These results indicated that sericin may
block DCI progression in rats by inhibiting TXNIP/NLRP3
neuroinflammation and neuronal apoptosis though SIRT1.

Published: August 2023

There is growing evidence that the humoral immune response plays a
significant role in the resolution of SARS-CoV-2. Patients with
inherited or acquired immunoglobulin deficiencies have a higher risk of
mortality, delayed viral clearance, and prolonged symptomatic infection,
and this contributes to viral evolution. Case reports/series have
implied a therapeutic role of monoclonal antibodies and convalescent
plasma (CCP) as well as antivirals in the management of seronegative,
symptomatic patients with SARS-CoV-2. In this review, we discuss the
existing evidence supporting the efficacy of the above-mentioned
treatment options and provide suggestions for management.

Authors: Dugan Katherine , Casale Jillian , DeSanto Heather , Dowling Colleen , Smoke Steven
Published: August 2023

Background Despite the limited evidence in immunocompromised
populations, the U.S. Food and Drug Administration issued an Emergency
Use Authorization in December 2021 for tixagevimab/cilgavimab (T/C)
indicated for COVID-19 pre-exposure prophylaxis. T/C has been used
widely at our center, therefore, we sought to determine the safety and
effectiveness of T/C for this indication in a cohort of kidney
transplant recipients. Methods This was a retrospective,
single-center, Institutional Review Board-approved study evaluating the
outcomes of 122 kidney transplant recipients who received
tixagevimab/cilgavimab for pre-exposure prophylaxis of COVID-19. Adult
patients who received T/C between January 1 , 2022
and March 31 , 2022 were reviewed for inclusion. The
efficacy population (n= 115) comprised those who received two doses and
the safety population (n=122) comprised those who received any amount of
T/C. The primary outcome was the rate of hospitalization for COVID-19
infection within six months of the first dose of T/C. The secondary
outcome was serious adverse events attributed to T/C. Results
Within six months of administration, low rates of hospitalization (2%)
and adverse events (2%) were found, with no incidence of heart failure,
myocardial infarction, or anaphylaxis. Conclusion Overall, our
study demonstrated that T/C in kidney transplant recipients was safe and
associated with low rates of hospitalization for COVID-19 infection when
susceptible Omicron subvariants were dominant.

Abstract: Purpose: Fundus fluorescein angiography (FFA) is usually done
when the patient is on an empty stomach. In case, if the patient is not,
their FFA is rescheduled for the next day to avoid the risk of
complications. The purpose of this study was to compare the
complications in patients who had undergone an FFA procedure on an empty
stomach to those who had breakfast immediately before the procedure.
Methods: In this study, 210 participants underwent FFA, of which 104
were fasting, and 106 had breakfast just before their procedure. In
these two populations, we compare the immediate and post-procedure
complications. Result: Patients who had FFA on an empty stomach were
more likely to experience nausea and vomiting (11.32% vs 7.69%), skin
allergies (1.89% vs 1.92%), and unconsciousness (0.94% vs 2.88%). In
either the fasting or control groups, no complications were
statistically significant (P>0.05). Conclusion: FFA is
generally a safe procedure, however, previous studies have observed
increased adverse events with people on empty stomachs. In individuals
with various systemic disorders and diets, our study found no increase
in adverse effects. Consequently, FFA shouldn’t be postponed in these
individuals who are not on a diet or who have systemic co-morbidities.

Phlebia genus is a relevant group of fungi with crucial role in numerous
ecosystems. In tropical and subtropical areas this genus allows the
efficient degradation of lignin and carbon recovery; however, the
majority of these fungal species remains undiscovered. The main purpose
of this work was to determine the enzymatic activity of extracellular
proteins of a novel Phlebia floridensis strain isolated in
Yucatan Peninsula, Mexico. The results that are reported here
demonstrate that soluble protein extract of P. floridensis can
degrade a broad spectrum of recalcitrant compounds. This induced protein
extract is able to modify not only phenolic and non-phenolic compounds,
but also anthroquinone dyes, even without addition of exogenous hydrogen
peroxide. Using LC-MS/MS, we were able to identify a novel
chloroperoxidase in enzymatic extract. As far as we know, this is the
first report about the presence of this type of enzyme in Phlebia genus.
Solidarity is a core capacity for emergency preparedness and response

Published: August 2023

At the beginning of the COVID-19 pandemic, Dr Tedros, Director-General
of the World Health Organization (WHO) called for solidarity in our
global response. While the call has echoed in various World Health
Assembly (WHA) resolutions and other major public health commitments,
many responses (local, national, and global) to the pandemic have seen
shortfalls in solidarity. This viewpoint uses the COVID-19 pandemic to
explore the roots of solidarity and trust and the political, economic,
and social values and forces that shape it. The shortfall in our
pandemic response exposes the limits and conditions of solidarity.
However, we argue that solidary can be strengthened to contribute to
global health security. Lastly, we reflect on the importance of
solidarity in emergency preparedness, response, and recovery and the
implications for public health practice.
Energy transfer between various electron populations via resonant interaction with whistler mode wave
Authors: Luzhkovskiy Artemiy A , Shklyar David R.
Published: August 2023

Electron energization in the Earth’s radiation belts caused by resonant
interaction with whistler mode waves currently is under intense
investigation. When the waves are excited due to cyclotron instability
in collisionless plasma, i.e., when the energy source for the waves is
the free energy of unstable electron distribution, particle energization
by excited waves is nothing but energy transfer from one group of
electrons to another mediated by the waves. An example of such a process
is considered in which a quasi-monochromatic whistler mode wave packet
with the frequency and the wave normal angle corresponding to the
maximum growth rate is excited at the equator. Since the maximum growth
rate corresponds to parallel propagating wave, only the first cyclotron
resonance particles play a part in this excitation. While propagating
from the equator towards the Earth, the wave normal vector becomes more
and more oblique, and all cyclotron resonances, in particular, Landau
resonance come into play. Wave-particle interaction at Landau resonance
leads to the wave damping and the corresponding particle energization on
the average. Moreover, we show that the mean square variation of
resonant particle energy greatly exceeds the average value, thus, the
energy increase of some particles is much larger than the Landau
resonance particles get from the wave on the average. This means that
the exchange of energy between different groups of particles through a
wave is a more efficient process than the amplification or damping of a
wave due to its resonant interaction with particles.
A multisite Stochastic Watershed Model (SWM) with intermittency for regional low flow and flood risk analysis
Authors: Brodeur Zachary Paul , Gupta Rohini S , Steinschneider Scott
Published: August 2023

Stochastic Watershed Models (SWMs) are an important innovation in
hydrologic modeling that propagate uncertainty into model predictions by
adding samples of model error to deterministic simulations. A growing
body of work shows that univariate SWMs effectively reduce bias in
hydrologic simulations, especially at the upper and lower flow
quantiles. This has important implications for short term forecasting
and the estimation of design events for long term planning. However, the
application of SWMs in a regional context across many sites is
underexplored. Streamflow across nearby sites is highly correlated, and
so too are hydrologic model errors. Further, in arid and semi-arid
regions streamflow can be intermittent, but SWMs rarely model zero flows
at one site, let alone correlated intermittency across sites. In this
technical note, we contribute a multisite SWM that captures univariate
attributes of model error (heteroscedasticity, autocorrelation,
non-normality, conditional bias), as well as multisite attributes of
model error (cross-correlated error magnitude and persistence). The SWM
also incorporates a multisite, auto-logistic regression model to account
for multisite persistence in streamflow intermittency. The model is
applied and tested in a case study that spans 14 watersheds in the
Sacramento, San Joaquin, and Tulare basins in California. We find that
the multisite SWM is able to better reproduce regional low and high flow
events and design statistics as compared to a single-site SWM applied
independently to all locations.
Polar lows and their effects on sea ice and the upper ocean in the Iceland, Greenland and Labrador Seas
Authors: Gutjahr Oliver , Mehlmann Carolin
Published: August 2023

Based on two case studies, we show for the first time that explicitly
resolving polar lows in a global climate model (ICON-Sapphire) with a
high resolution of 2.5 km in all components (atmosphere, ocean, sea ice
and land) leads to strong heat loss from the ocean near the sea ice edge
and from leads and polynyas in the ice cover. Heat losses during marine
cold air outbreaks triggered by polar lows lead to the formation of
dense water in the Iceland and Greenland Seas that replenishes the
climatically important Denmark Strait Overflow Water (DSOW). Further
heat losses and the rejection of brine during ice formation in polynyas,
such as the Sirius Water Polynya in northeast Greenland, contribute to
the formation of dense water over the Greenland shelf. In the Labrador
Sea, polar lows intensify cold air outbreaks from the sea ice and
quickly deepen the ocean mixed layer by 100 m within two days. If
mesoscale polar lows and kinematic features in the sea ice are not
resolved in global climate models, heat loss and dense water formation
in (sub-)polar regions will be underestimated.

Published: August 2023

  

Objective:

We sought to determine real-world accuracy of inpatient continuous glucose monitoring (CGM) at multiple levels of acuity in a large safety-net hospital. 

Research Design and Methods:

We analyzed records from hospitalized patients on Dexcom G6 CGM including clinical, point of care (POC) and laboratory (Lab) glucose, and CGM data. POC/Lab values were matched to closest timed CGM value. Encounters were divided into Not Critically Ill (NCI) versus Critically Ill (CI). CGM accuracy was evaluated.

Results:

Paired readings (2,744 POC-CGM; 3,705 Lab-CGM) were analyzed for 233 patients/239 encounters (83 NCI, 156 CI). POC-CGM Aggregated and Average MARD were 15.1% and 17.1%. Lab-CGM Aggregated and Average MARD were 11.4% and 12.2%. Accuracy for POC-CGM and Lab-CGM was 96.5% and 99.1% in CEG zones A/B. 

Conclusions: 

Real-world accuracy of inpatient CGM is acceptable for NCI and CI patients. Further exploration of conditions associated with lower CGM accuracy in real-world settings is warranted. 
Colchicine Effect of Mitosis Root Tip by Banana Kepok Yellow (Musa paradisiaca L.) Polyploid Explants
Authors: Yana Dellya Vivi , Ernawiati Eti , Agustrina Rochmah , Handayani Tundjung Tripeni
Published: August 2023

Colchicine can inhibit spindle formation so that doubled chromosomes fail to separate during anaphase cytologically to induce mutations that produce polyploid plants. Yellow kepok banana is a triploid banana. The supply of yellow kepok bananas is hampered by conventional cultivation methods and the limited availability of quality seeds. This study aims to determine the effect of adding colchicine compound to tissue culture media on the mitotic index, chromosome number, and chromosomal abnormalities in yellow kepok bananas and the formation of polyploid plantlets. This study was included in the experimental study by conducting mitotic preparation and observing morphology after the test sample was induced by colchicine. The results of the research that has been done show that the addition of the compound colchicine to the tissue culture medium of yellow kepok banana causes a decrease in the mitotic index, an increase in the number of chromosomes, the presence of chromosomal abnormalities, the formation of polyploid plantlets, and an increase in the number of roots, but there is a reduction in root length.
