Published: April 2022

The postoperative recurrence of neuroblastoma (NB) patients is an
essential reason for the high mortality of NB due to the lack of early,
non-invasive, and dynamic strategies for monitoring NB recurrence.
Therefore, whether the plasma circulating cell-free MYCN gene as an
indicator for monitoring of NB recurrence was systematically evaluated.
The MYCN copy number and NAGK (reference gene) copy number ratio (M/N)
in plasma and corresponding tumor tissues of NB patients was detected
using an economical, sensitive and specific single-tube dual RT-PCR
approach developed in this study. The plasma M/N ratio of the MYCN gene
amplification (MNA) group (N = 25, median M/N ratio = 4.90) was
significantly higher than that of the non-MNA group (N = 71, median M/N
ratio = 1.22), P < 0.001. The M/N ratio in NB plasma (N = 60)
was positively correlated with the M/N ratio in NB tumor tissue (N =
60), with a correlation coefficient of 0.9496. In particular, the
results of dynamic monitoring of postoperative plasma M/N ratio of NB
patients showed that an abnormal increase in M/N ratio could be detected
1-2 months before recurrence in NB patients. In summary, the single-tube
double RT-PCR approache can be used to quantitatively detect MYCN copy
number. The copy number of MYCN in the tissue and plasma of NB patients
is consistent with each other. More importantly, the circulating
cell-free MYCN gene of NB patients can be used as a monitoring indicator
for early, non-invasive, and dynamic monitoring of NB recurrence.
Phragm\’{e}n-Lindel\”{o}f type alternative results for the solutions to generalized heat conduction equations
Authors: Li Yuanfei , Tang Gusheng , Chen Xuejiao
Published: April 2022

This paper investigates the spatial behavior of the solutions of the
generalized heat conduction equations on a semi-infinite cylinder by
means of a first order differential inequality. We consider three kinds
of semi-infinite cylinders with boundary conditions of Dirichlet type.
For each cylinder we prove the Phragmén-Lindelöf alternative for the
solutions. In the case of decay we also present a method for obtaining
explicit bounds for the total energy.
Some Results on Coupled Coincidence Points in Vector Quasi Cone Metric Spaces over Banach Algebras with Satisfactory Cones
Authors: Bakr Sahar Mohamed Ali Abou
Published: April 2022

Abstract. In this paper, let (X;C;DC; χ) be a complete parametric vector
quasi cone metric space over a Banach algebra A, C be a cone in A that
contains some semi-interior points, χ be a metric parameter in C with
spectral radius greater than or equal one and T from X xX to X be a
generalized contraction mapping its parametric contractions are vectors
in C, with these settings and without relying on the assumptions of
normality and solidness of C we proved the existence of coupled
coincidence points of the mapping T and hence generalized many theorems
concerned with the existence of coupled coincidence points of such types
and we supported these results with some illustrative examples.
Oscillation of nonlinear third-order neutral delay differential equations with unbounded neutral coefficients and distributed deviating arguments
Authors: Sun Yibing , Xie Qiangqiang , Zhao Yige
Published: April 2022

Oscillation of solutions of differential equations enjoys wide range of
applications, such as physical sciences, population growth and life
sciences. In this paper, we discuss the oscillation of third-order
nonlinear neutral delay differential equations with unbounded neutral
coefficients and distributed deviating arguments. By using comparison
principles, we relax the restricted conditions and establish new
oscillation theorems, which extend and perfect some related results in
the literature. Finally, our main results are illustrated by two
examples.

Authors: Dhillon Parmpreet , Morrone Kerry , Hsu Kevin , Gomes William , Silver Ellen , Lax Daniel , Peng Qi , Lee Seon Kyu , Manwani Deepa , Mitchell William
Published: April 2022

Background: Flow artifact, intrinsic to Magnetic Resonance Angiography
(MRA), is dependent on technical parameters and can lead to
overinterpretation of stenosis. Degree of cerebrovascular stenosis in
pediatric patients with sickle cell anemia (SCA) informs need for
chronic transfusion therapy, which may have significant risks. The
primary objective of this study was to document any change in stroke
prevention therapy that could be attributed to the implementation of a
standardized MRA scanning protocol. Procedure: A standardized MRA
scanning protocol with an echo time of <5 msec was implemented
at Montefiore Medical Center in May 2016. Retrospective chart review
identified 29 patients ≤ 21 years with SCA cerebral vasculopathy and an
MRA head pre- and post-May 2016. Level of arterial stenosis on MRA, echo
time, and treatment plans were documented both pre- and
post-implementation. McNemar analysis determined the significance of
change in treatment plans before and after implementation of the
standardized scanning protocol. Results: Previously seen stenosis was
re-classified to a lower degree in 12/29 patients (41%). Notably, 6
patients had a reclassification of vasculopathy leading to
discontinuation of chronic transfusion therapy whereas 0 patients
required escalation of therapy to chronic transfusions. McNemar analysis
showed this difference to be statistically significant (p = 0.042).
Conclusion: Minimizing flow artifact with echo time <5msec
improves accurate interpretation of true cerebrovascular disease and
ensures appropriate treatment plans are in place for stroke prevention.
This is especially important when trying to implement “TCD With
Transfusions Changing to Hydroxyurea (TWiTCH)” clinical trial results
in the real-world setting.
Legume germination is delayed in dry soils and in sterile soils devoid of microbial mutualists: implications for upward range expansions
Authors: Keeler Andrea , Rafferty Nicole
Published: April 2022

Climate change is affecting species and their mutualists and can lead to
interaction weakening and loss. Through independent shifts in partner
phenology and distribution, climatic stress can separate mutualists,
leading to alterations in partner functional traits and fitness. Here,
we explored the effects of drying soils and the loss of microbial
mutualists via soil sterilization on legume germination success and
phenology, focusing on how a loss of mutualisms with soil microbial
species can alter legume early life traits. In particular, we assessed
the effects of mutualism loss via soil sterilization, increased drought,
or introduction to novel soils found beyond the current distributions of
two focal legume species in subalpine environments. Through common
garden experiments in controlled environments, we found evidence that
soil sterilization (and consequent microbial absence) and dry soils
caused phenological delays of 2-5 weeks in germination date, likely as a
result of interaction loss between legumes and germination-promoting
soil microbes, such as mutualistic rhizobia. Delays in germination
caused by a mismatch between legumes and beneficial microbes could
negatively affect legume fitness through increased plant-plant
competition later in the season. Additionally, we found evidence of the
presence of beneficial microbes beyond the current elevational range of
our focal legumes which may allow for expansion of the leading edge,
though harsh abiotic factors in the alpine may hinder this. Alterations
in the strength of soil microbe-legume mutualisms may lead to reduced
fitness and altered demography for both soil microbes and legumes.
Power-gated Static Random-Access Memory-based Physically Unclonable Function
Authors: Zheng Yujin , Bystrov Alex , Yakovlev Alex
Published: April 2022

An architecture and implementation of a Physically Unclonable Function
(PUF) based on Static Random-Access Memory (SRAM) is developed to
accommodate stochastic processing of PUF Response. An 8T-PUF cell is
built to eliminate data retention and maximise physical mismatch. The
power gating method is used to perform measurement on a subset of PUF
cells repeatedly at a high rate. Two-phase power gating is applied
selectively to parts of PUF matrix and is designed for minimising EMI
and crosstalk amongst the cells during metastability resolution whilst
maintaining high performance. The design is meant to serve as a platform
for extraction of a variety of stochastic metrics for subsequent
inclusion into PUF Responses, which comprises the novelty of the
approach.
Improved Resolution Fourier Ptychography Scheme Using Oil-Filled Dome-Shaped LED array
Authors: Mayani Mahdieh Gholami , Hussain Nazabat , Breiby Dag , Akram Muhammad
Published: April 2022

Utilizing angular-varied illumination in Fourier Ptychography (FP), the
resolution of optical microscopes can be increased and the phase of the
sample can also be recovered while maintaining a wide field-of-view. In
this work, an FP microscopy imaging setup is demonstrated using a 10X
0.28NA objective lens and a dome-shaped LED array illuminator. By
increasing the refractive index of the medium between the sample and
light sources using oil filled dome, a synthetic system NA of 0.68 is
achieved using only 37 LEDs. The measured resolution of 345 nm at a
wavelength of 530 nm closely matches the theoretical prediction.
Furthermore, the results of the oil-medium illumination are compared to
free-space illumination. The oil immersion on the illumination side
effectively enhances the illumination NA as compared to air and reduces
the need for far off-axis LEDs. The result is high-resolution FP imaging
with relatively fewer LEDs providing both short capture and
reconstruction times.

U radu autor na temelju arhivskih izvora analizira proces likvidacije Dioničarskoga društva Lonjskopoljske željeznice te podržavljenje pruga u
njegovu vlasništvu nakon završetka Prvoga svjetskog rata. Poslije raspada Austro-Ugarske Monarhije sjedište Dioničarskoga društva premješta se iz Budimpešte u Zagreb. Pruge Društva bile su Dugo Selo – Novska i Banova Jaruga – Pakrac. Stvaranjem Države Slovenaca, Hrvata i Srba potpale su pod nadležnost novoosnovanoga Generalnog ravnateljstva željeznica Države Slovenaca, Hrvata i Srba u Zagrebu, a stvaranjem Kraljevstva Srba, Hrvata i Slovenaca pod nadležnost novoosnovane Direkcije državnih željeznica Zagreb. Poslije dugogodišnjih pregovora Kraljevina Jugoslavija zaključila je 7. veljače 1931. sporazum o otkupu s
grupom od 24 mađarska dioničarska društva vicinalnih željeznica, udruženih u koncern „Pruga d.d.” sa sjedištem u Zagrebu. Među njima je bila i Lonjskopoljska vicinalna željeznica. Time je i prestao razlog njezina postojanja. Na temelju navedenog Kraljevski sudbeni stol kao trgovački sud u Zagrebu upisao je 6. lipnja 1932. u svoj trgovački registar likvidaciju Dioničarskoga društva Lonjskopoljske željeznice. Kada je uslijed dovršene likvidacije Društvo prestalo s radom, Okružni sud u Zagrebu kao trgovački sud brisao ga je 12. travnja 1933. iz svojega trgovačkog registra. Država je uknjižila pravo vlasništva nad nekretninama Lonjskopoljske vicinalne željeznice tek 1936., a kompletna regulacija imovinsko-pravnih odnosa na nekretninama Lonjskopoljske željeznice završila je tek 1951.
Can Your Audit Team Effectively Multitask? It Might Depend on How They Communicate
Authors: Brazel Joseph F. , Brown Veena Looknanan , Sidgman Juergen
Published: April 2022

This article summarizes Sidgman, Brown, and Brazel (2021) which demonstrates that, when multitasking, the performance of audit teams communicating in-person is greater than the performance of teams using computer-mediated communication (discussion boards and chatrooms). In the audit setting, multitasking is unavoidable and pervasive; in-person communication is not always an option. To facilitate multitasking, engagement team communications have extended in-person interactions to computer-mediated communication (CMC) technologies. However, little is known about the performance of multitasking teams under these alternative modes of communication (in-person, discussion boards, and chatrooms). Contrary to expectations, we find that participants' familiarity with, and preference for, chatroom features (similar to text messaging) may have offset the benefits previously attributed to discussion boards (similar to email). This finding is timely, given the pandemic-induced environment of remote and hybrid work, as it informs practitioners on audit teams' multitasking effectiveness while using CMC.
Severe Bradycardia Occurring After Assisted Mouth Opening: A Case Report
Authors: Hayakawa Yoshio , Fujii-Abe Keiko , Nakano Takuya , Suzuki Masayuki , Kawahara Hiroshi
Published: April 2022

We report a case of severe bradycardia during general anesthesia due to reduced atrioventricular conduction capacity believed to have been caused by the trigeminocardiac reflex (TCR). A 46-year-old woman was scheduled for intraoral scar revision under general anesthesia. When the surgeon opened her mouth intraoperatively, the patient's blood pressure immediately increased, and she developed significant bradycardia and a transient Mobitz type II second-degree atrioventricular block. It was assumed that the mandibular division of the trigeminal nerve (V-3) was stimulated by the surgeon stretching the patient's mouth open while remifentanil simultaneously provided sympatholytic effects, resulting in activation of the TCR. The patient quickly responded well to atropine and had no additional complications.

ABSTRACT
COVID-19 is an infectious disease caused by SARS-CoV-2. This disease is designated as a pandemic because it has spread throughout the world. In an effort to break the chain of distribution, the government issued a new policy, namely replacing teaching and learning activities using the online system. Online learning using the dense zoom meeting application can result in physical and psychological fatigue which is called zoom fatigue. However, not many people know how to prevent and overcome them. Counseling is held in order to provide information to the public on how to prevent and overcome zoom fatigue during the pandemic. The steps used are to provide material and pre-test and post-test. This aims to determine the knowledge of the counseling participants on how to prevent and overcome zoom fatigue during the pandemic. The comparison of the average correct answers for the pre-test was 75.42% and the post-test was 86.5%. The results obtained were assessed using normality and homogeneity tests and paired t-test, obtained p value <0.005. This shows an increase in knowledge after the material given by the presenter. Therefore, this outreach activity succeeded in increasing knowledge about how to prevent and overcome zoom fatigue during the pandemic.
The Role of Competitiveness Mechanism Protection of Marketing Performance: Resource-Advantage Theory Perspective
Authors: Panjaitan Roymon
Published: April 2022

The study aims to determine the conceptual and empirical flow of inconsistencies in entrepreneurial, creative relationships on marketing performance centred on protecting competitiveness mechanisms. This conception is built to explore the critical role of protecting the competitiveness mechanisms of entrepreneurial creativity and product innovativeness. Optimization of post-pandemic marketing performance requires creativity and innovativeness and the importance of safeguarding competitiveness mechanisms. Seven hypotheses were developed and tested with the SEM-PLS technique in a sample frame of 230 MSMEs in Central Java, Indonesia. The study's findings contribute to the protection of competitiveness mechanisms conceptually, both empirically and practically. First, directly entrepreneurial creativity has a positive impact. On the contrary, there is a negative relationship of products innovatively in marketing performance. Second, the protection of competitiveness mechanisms can positively bridge innovative product relationships and entrepreneurial creativity in marketing performance. Third, the potential mediator of protection of competitiveness mechanisms can overcome the negative association of product innovativeness on marketing performance. The practical implications of criticizing MSMEs are not enough just creative and innovative, but still, require the protection of resource excellence. External factors protecting intellectual competitiveness mechanisms contribute to providing a competitive advantage. The theoretical implication is that the theory of competing resource advantages that a competitor's scarce resources have has the potential to gain a comparative advantage.

Published: April 2022

Stosowanie środków ochrony indywidualnej (ŚOI; PPE, z ang. personal protective equipment) jest najpopularniejszym sposobem zmniejszenia narażenia pracownika na czynniki szkodliwe występujące w środowisku pracy. Jedną z form ŚOI, niechętnie stosowaną przez pracowników, są środki ochrony układu oddechowego. Ich zadaniem jest ochrona pracownika przed wdychaniem zawieszonego w powietrzu aerozolu. Celem badań było poznanie postaw pracowników wobec obowiązku stosowania ochrony układu oddechowego w trakcie pracy – przed pandemią COVID-19 i w czasie jej trwania. Do realizacji celu badania utworzono autorską ankietę, korzystając z kwestionariusza formularza Google. Ankieta zawierała 25 pytań, w tym pytanie filtrujące, które wykluczało osoby inne niż grupa docelowa. Uzyskane wyniki poddano analizie statystycznej, korzystając z programu Statistica v.12.0. Główną ochroną stosowaną przez pracowników w trakcie pracy jest półmaska. Przed pandemią nie wszyscy pracownicy byli pozytywnie nastawieni do noszenia ŚOI. W grupie osób, które nie miały zdania na temat stosowania ochrony dróg oddechowych, 31,71% wymienia zużyte lub uszkodzone ŚOI na nowe, co potwierdzono statystycznie. Pracownicy zwracają dużą uwagę na wygodę noszenia ŚOI.
Assessment of relationships between reactions of horses during everyday use
Authors: Ziemiańska Agnieszka , Rozempolska- Rucinska Iwona
Published: April 2022

The aim of the study was to assess whether observations of a horse’s reactions during everyday activities can be used to predict its behaviour during riding. The study was conducted on 60 horses of the Malopolski breed, aged 5 to 15 years. The horses were kept in three riding stables, in a box system. The data were obtained from an interview conducted with a person responsible for the daily grooming and handling of the horses. Observations covered at least half a year of daily contact with the horse. The horses’ behaviour was analysed before feeding, during preparation for riding, and during riding. The research shows that aggressive behaviours before feeding may be a marker of inappropriate reactions before and during recreational riding. Initial activities preparing the horse, i.e. approaching the animal, grooming, bridling and saddling, can be used as a ‘test’ to evaluate and predict the quality of the ride. Problems with these procedures also suggest significant problems during riding. The behaviour of the animal before feeding and during preparations for riding should be considered an important indicator of riding safety and comfort.
Environmental enrichment for grey seals (Halichoerus grypus) in captive environment
Authors: Łypik Oliwia , Zieliński Damian
Published: April 2022

Grey seal (Halichoerus grypus) is one of the most popular marine mammals found in the Baltic Sea and North Atlantic. It is protected worldwide because of an important role it plays in the ecosystem along with other marine predators, also because it is an indicator. It arouses both the sympathy and aversion of the public opinion, probably caused by insufficient knowledge about this species. Due to the high adaptability, captive individuals adapt easily to the artificial environment, but this does not exempt them from the necessity of providing them with the comfort of living in closed conditions. The study concerns the design and application of environmental enrichments for grey seals living in zoos. They aim to improve the welfare of those animals which, by living in small enclosures and impoverished environment, are not able to display the full range of species behavior. Stimulation with new elements is also important in preventing aggression, apathy, and stereotypies. The proposed enrichments are easy to implement and relatively low-cost, intended for use in zoos and other organizations or institutions keeping specimens of this species. The results of the preliminary observation showed that grey seals reacted positively to some of the proposed enrichments and the time of expressing the food behavior has extended. Further issues require additional and more detailed observations.
Effect of different liquids on APC flash-free ceramic bracket’s color stability, shear bond strength, and slot surface roughness
Authors: Canbaz Çevik Şeyda , Camcı Hasan , Aslantaş Kubilay
Published: April 2022

Objective:

The aim of this in vitro study was to evaluate the effect of thermal aging and five different discolouring solutions on the shear bond strength (SBS), discoloration, and slot surface roughness (SSR) of Flash-Free ceramic brackets.

Methods:

A total of 70 human premolar teeth were randomly divided into seven groups: group 1: no procedure was performed; group 2: Only thermal cycling (TC); group 3: TC + immersion in cherry juice for 72 hr; group 4: TC + immersion in coffee for 72 hr; Group 5: TC + immersion in Coke for 72 hr; group 6: TC + immersion in artificial gastric acid for 24 hr; group 7: TC + immersion in artificial saliva for 72 hr. SBS values were determined by using a universal testing machine. The discolouration was evaluated using a Vita Easy Shade spectrophotometer which is based on the International Commission on Illumination system (CIE Lab colour system). A 3D optical profilometer was used to measure the roughness of the bracket slot bases.

Results:

Coke, coffee, cherry juice, and gastric acid all significantly increased slot surface roughness. There was, however, no statistically significant difference in the roughness caused by these liquids. The lowest SBS value was observed in the gastric acid group. Gastric acid and Coke were observed to induce the largest colour change.

Conclusions:

Thermal aging and different liquids cause discolouration and increased surface roughness on APC flash-free brackets. The adhesive bond strength was clinically acceptable even after immersion in gastric acid.

The pre-pandemic era has been established the settled living ecosystem for orchestral musician in Indonesia, nevertheless, due to the government's policy to combat the virus since March 2020 which is applying the social restriction on a large scale, those within creative sectors have totally ceased their activities. As time goes by, online-virtual-concert has enlivened musical creating and performing. It spread globally and was responded as an opportunity by the state representation so did by the private sectors who have developed the platforms to accommodate the musician rights as brought by UNESCO discourses, one of formulated as follows “musicians can express themselves through music and get fair remuneration from it.” The developed platforms had played a big role as a leverage, both during the pandemic and in the post-pandemic as has predicted and discussed in a two-way Focus Group Discussion methods (FGD), it taken from any webinars sessions involved the expert, officials, and the practitioners which concluded that instead of waiting a crisis assumed just taken place for a moment while waiting for the usual state return, it has been realized globally as an evidence as well as a signs that the new living ecosystem for orchestral musicians in Indonesia have just begun to change.

Masyarakat Betawi yang mendiami kota Jakarta mempunyai suatu bentuk ensambel musik yang dinamakan Gambang Kromong. Awal mulanya musik Gambang Kromong dalam pertunjukannya mempergunakan alat musik tranisional yang terdiri dari Gambang, Kromong, Sukong, Tehyan, Kongahyan, Basing/suling, Ningnong, Jutao, Kecrek, Kempul, dan Gong. Seiring dengan perkembangan zaman yang melingkupi kota Jakarta, maka musik tersebut memasukan alat musik Barat dalam pertunjukannya. Pengaruh yang terjali dengan penggunaan alat musik Barat yaitu penambahan beberapa repertoar lagunya yang memasukan lagu keroncong, dangdut, dan pop dalam sajiannya. Hal ini membuat perkembangan musik Gambang Kromong menjadi lebih banyak dinikmati oleh masyarakat pendukungnya dengan sebutan Gambang Kromong Asli dan Kombinasi.AbstractCollaboration of Western Musical Instruments and Trasidional Musical Instruments in Gambang Kromong Betawi.

Published: April 2022

Objetivo: caracterizar los parámetros que determinan la calidad de los vinos de la variedad Tempranillo elaborados con uvas provenientes de tres zonas geográficas del estado de Chihuahua, México. Metodología: se determinó la calidad en vinos de doce meses de maduración, obtenidos de uvas producidas en tres viñedos: Faciatec, Hacienda Bustillos y Paralelo Meridiano; se les efectuaron análisis fisicoquímicos, acidez total titulable (ATT), índice de polifenoles totales, así como composición del color; evaluados en un diseño de bloques al azar con tres repeticiones. Resultados: el pH y ATT, se presentaron niveles óptimos para vinificación, sin embargo, la acidez volátil presenta niveles bajos; el vino con mayor grado alcohólico y composición fenólica, fue el vinificado con bayas del viñedo Faciatec, es apropiado para envejecer, además por sus características cromáticas y sensoriales, presentó mayor tonalidad. Limitaciones: condiciones climáticas prevalecientes durante el periodo de estudio y falta de vigilancia de entrada de personas a los viñedos. Conclusiones: la altura sobre el nivel del mar, temperatura y precipitación durante la madurez de las bayas, influyen en la vinificación, al impactar en las características fenólicas y cromáticas del vino, por lo tanto, el que proviene del viñedo de Faciatec, probablemente, sea el más apto para añejamiento en barrica, y el resto para vinos jóvenes.
SORET AND VARIABLE THERMAL CONDUCTIVITY EFFECTS ON HYDRO-MAGNETIC RADIATING FLUID PAST A VERTICAL PLATE WITH POROUS MEDIUM
Authors: Raju M. Santha , Raju G.S.S.
Published: April 2022

Thermal diffusion and variable thermal conductivity effects on unsteady magnetohydrodynamic (MHD), heat and mass transfer flow past an infinite vertical porous plate have been investigated and analyzed numerically. The resultant flow governing equations are resolved numerically by the finite-difference scheme of the Crank-Nicolson type implicit method. The non-dimensional velocity, fluid temperature, and species concentration distributions are conferred through graphs for different fluid parameters involved such as joule-heating parameter, suction parameter, chemical reaction parameter, radiation parameter, etc. The coefficient of skin friction, Nusselt number and Sherwood number were tabulated. The concentration of the fluid rises with an increase in Soret number, whereas the Sherwood number reduces due to its increase.

Calendering is a mechanical finishing technology used in the leather, textile, and paper industry, with the mechanism of reshaping and deforming fibers of the web to be calendered with the help of pressure and heat transfer. In this paper, a comparative study has been done to examine the flow of heat inside the calender nip using an unsteady heat conduction equation with specific initial and boundary conditions. The outcomes achieved by utilizing the new homotopy perturbation method and finite difference method have been compared with the exact solution. The achieved outcomes reveal the accuracy, effectiveness, and reliability of techniques applied. It is observed that the outcomes achieved by the new homotopy perturbation method are more accurate than those obtained by the finite difference method.
