A Discrete Retarded Gronwall-Bellman Type Inequality and its Applications to Difference Equations
Authors: Chen Feichao , Li Desheng , Guang Zhang
Published: February 2022

In this paper we present a new discrete retarded Gronwall-Bellman type
inequality. As applications, the dynamics of some delay difference
equations are studied. First, the asymptotic behavior of solutions for
scalar difference equation $\Delta
x(n)=-a(n)x(n)+B(n,x_n)$ is discussed, and some new criterion on the
asymptotic stability of the zero solution are obtained under weaker
assumptions. Then the dissipativity of a nonautonomous delay difference
system with superlinear nonlinearities is investigated. By using the
inequalities established here, it is shown that the discrete set-valued
process generated by the system possesses a unique global pullback
attractor.
Threshold Secret Sharing with Geometric Algebra
Authors: Silva David William Honorio Araujo da , Harmon Luke , Delavignette Gaetan
Published: February 2022

As establishing a foundation for a new line of investigations on
threshold secret sharing schemes with geometric algebra (GA), we propose
a variation of a well-known threshold secret sharing scheme introduced
by Adi Shamir in 1979, a cryptographic solution that allows a secret
input to be divided into multiple random shares which are then sent,
each one, to distinct parties. The computation of these shares is done
so that there are proper subsets of these shares that allow
reconstructing the secret input using polynomial interpolation. To
reconstruct the secret input, Shamir’s scheme requires a minimum number
of shares, smaller than the total number of shares, referred to as a
threshold. Any number of shares smaller than the threshold reveals
nothing about the input secret. The random shares are generated such
that each party can perform computations, generating a new set of shares
that, when reconstructed, are equivalent to performing those exact
computations directly on the secret input data. Our variant replaces the
algebra in which the original secrets lie from integers to GA while
preserving fundamental properties in Shamir’s scheme, such as perfect
secrecy and idealness (both secret and random shares are members of the
same space). As a direct result, any application in GA dealing with
multivectors can immediately add threshold security using our scheme.
Non-GA applications can also benefit from our results by using
multivectors as a vessel for sharing multiple secrets at once.

Active Surveillance for Patients with Micro Papillary Thyroid Cancer in UK
Authors: Maniam Pavithran , Harding Noah , Li Lucy , Adamson Richard , Hay Ashley , Nixon Iain
Published: February 2022

Background The incidence of thyroid cancer is increasing globally due to
the increase in detection of subclinical, low volume papillary thyroid
microcarcinomas (PTMC) (<1cm). Several international groups
have recommended an active surveillance approach for this low-risk
disease. In contrast to many other countries, the UK’s approach to
thyroid nodules is to avoid detection of incidental lesions where
appropriate. Objective This study aims to establish the proportion of
patients with thyroid cancer in the UK that would benefit from active
surveillance. Design, participants, and outcome measures: Individuals
with PTMC in NHS Lothian from 2009-2020 were reviewed from a local
thyroid cancer database. The mode of detection of PTMC and proportion of
patients who might benefit from active surveillance were established.
Results From 651 individuals with differentiated thyroid cancer managed
over 12-year period, 185 individuals with PTMC were identified (28.4%).
The majority of PTMC 151/185 (81.6%) were either diagnosed
post-operatively following thyroidectomy for benign disease or with
nodal disease. Only 24 individuals with PTMC were identified following
palpable thyroid nodule, incidental finding on imaging and surveillance
screening. Therefore, when the indication for surgery was considered,
only 24/651 (3.7%) patients were identified pre-operatively and would
therefore be realistic candidates for active surveillance. Conclusion
Less than 4% of patients with thyroid cancer in the UK would be
appropriate for active surveillance. Rather than developing programs to
deal with this minority of patients, focus should be maintained on
minimizing detection of these low-risk cases.
On some enriched contractions in Banach spaces and an application
Authors: Mondal Pratikshan , Garai Hiranmoy , Dey Lakshmi
Published: February 2022

In this paper, we introduce two new types of enriched contractions, viz.,
enriched A-contraction and enriched A-contraction. Then we obtain fixed
points of mappings satisfying such contractions using the fixed point
property of the average operator of the mappings. Further, we study the
well-posedness and limit shadowing property of the fixed point problem
involving the contractions, and give some examples to validate the results
proved. Our work improves Berinde and P?curar?s recent results on different
kinds enriched contractions and some well known classical fixed point
results. As an application, we prove an existence and uniqueness theorem for
an integro-differential equation.

Let X and Y be topological spaces and f : X ? Y be a continuous function. We
are interested in finding points of X and Y at which f is open. We will show
that if X is developable, the set of points of openness of f in X is a G?
subset of X. If X is developable and f is closed, then the set of points of
openness of f in Y is a G? subset of Y. These will extend some results of S.

Some Tauberian theorems for Cesàro summability of double integrals over R2+
Authors: Fındık Göksen , Çanak İbrahim
Published: February 2022

In this paper, we obtain one-sided and two-sided Tauberian conditions of
Landau and Hardy types for (C,1,0) and (C,0,1) summability methods for
improper double integrals under which convergence of improper double
integrals follows from (C,1,0) and (C,0,1) summability of improper
double integrals. We give similar results for (C,1,1) summability method
of improper double integrals. In general, we obtain Tauberian conditions in
terms of the concepts of slowly decreasing (resp. oscillating) and strong
slowly decreasing (resp. oscillating) functions in different senses for
Ces?ro summability methods of real or complex-valued locally integrable
functions on [0,?) x [0,?) in different senses.

Anatomy and Physiology of Vestibular System
Authors: Chi Gary , Crowson Matthew
Published: February 2022

A comprehensive understanding of vestibular anatomy and physiology is essential to interpreting and treating vestibular disorders. The otolithic organs and semicircular canals are the major components of the vestibular system. Each contains hair cells, mechanosensory cells responsible for converting mechanical signals produced by the body into electrical signals. Each hair cell produces a resting discharge rate. This rate can be increased or decreased as a result of head motion, with the magnitude of change dependent on the direction and strength of the motion. These signals are sent to the vestibulocochlear nerve which interprets and integrates the information with input from other sensory organs. The main role of the vestibular system is to maintain balance and detect angular and linear acceleration. Angular acceleration is detected by the semicircular canal via interpretation of endolymph flow caused by head movement. Linear acceleration is detected by the otolith organs through gravity-dependent otoconia movement. This article serves as a review for the structure and function of the major vestibular organs.

This review contains, 9 figures, 1 table, and 8 references

The effect of non-thermal plasma Jet on bacterial biofilms and plasmid DNA
Authors: Sulaiman Saba Mawlood , Sulyman Safa Aldeen Abdulla
Published: February 2022

The effect of non-thermal discharge plasma (DBD) on the inhibition of both gram-positive and gram-negative biofilms bacteria was examined at different plasma exposure times and gas flow. This effect induces damage to aqueous plasmid DNA. It reveals inactivation in bacterial biofilms for both types of bacteria with an increase in time of direct exposure to plasma and an increase in gas flow. The presence of positive bacteria outweighs the negative bacteria in susceptibility to inhibition. The resulting fractions of the DNA indicate whole DNA double-strand breaks and were determined using agarose gel electrophoresis. The damage level induced in the plasmid DNA is also enhanced with increased plasma irradiation time.
Brown trout in the Falkland Islands: invasion ecology, population structure and genetic diversity
Authors:   , Minett Jessica F.
Published: February 2022

Biological invasions are important causes of biodiversity loss, particularly in remote islands. Non-native salmonids, such as brown trout (Salmo trutta), have been widely introduced throughout the Southern Hemisphere, impacting endangered native fauna, particularly galaxiid fishes, through predation and competition. However, due to their importance for sport fishing and aquaculture, they are often protected, and any attempts to curtail their impacts are generally met with limited support, which poses a conservation conundrum. The best prospect of protecting native galaxiids is to predict where and how salmonids might disperse. This thesis aims to answer three main questions about brown trout in the Falkland Islands in order to provide resource managers with information to facilitate conservation planning to minimize the impacts of brown trout on native galaxiids. (1) determine the distribution of invasive brown trout and native zebra trout, Aplochiton zebra and Aplochiton taeniatus. (2) estimate patterns of movement and (3) assess the population structuring and estimate levels of gene flow between different rivers and populations of brown trout in the Falklands. To meet these aims, I used state-of-the-art methods, including SNP genotyping, stable isotope analysis, acoustic tagging, and environmental DNA (eDNA) analysis. The results of this thesis suggest that establishment success (calculated as the proportion of historical introductions where brown trout became established) was ~88% and that brown trout are continuing to spread from their original sites of introduction. The native Aplochiton species have disappeared from most rivers invaded by brown trout. Four genetically distinct clusters of brown trout were identified, with high levels of gene flow indicating widespread dispersal of brown trout across the Falkland Islands. Without strong containment, brown trout are predicted to invaded nearly all suitable freshwater habitats in the Falklands within the next ~70 years, which might put native galaxiids at a high risk of extinction.

Reading has an influential role in language achievement where each student has their own preferred way to guide them which is called learning styles. The researcher interested in conducting the comparative study because students’ learning styles i.e., visual, auditory, and kinesthetic have dissimilar attainment in reading comprehension. The objectives of this research were to determine i) the significant difference in students’ reading comprehension achievement among students with visual, auditory, and kinesthetic learning styles and ii) the highest and lowest reading aspect of each VAK student’s achievement. The approach of this research was quantitative. The sample of this research was 30 students in X IPA 6 of SMAN 3 Bandar Lampung chosen by purposive sampling method. Questionnaires and reading test were used to collect the data. The data were analyzed by using One Way Anova and MANOVA in SPSS 17.0 for Windows. The result showed there was a significant difference in students’ reading comprehension achievement based on their learning style since the f-value was 1.287 with the alpha 0.07. In addition, the result of the VAK students’ achievement showed the highest aspect of visual students was determining vocabulary, while the highest aspect of auditory and kinesthetic students was determining reference. The lowest aspect of visual and auditory students was finding main idea while the lowest aspect of kinesthetic students was making inference.

An analysis of students’ grammatical errors in translating Indonesian recount text into English made by the first grade of senior high school
Authors:   Universitas Lampung, Sari Nilam Puspita , Putrawan Gede Eka ,   Universitas Lampung, Deviyanti Rafista ,   Universitas Lampung
Published: February 2022

This research was aimed at finding out types of grammatical errors and investigating types of errors that were most and least frequently made by students based on Communicative Effect Taxonomy that were found in students’ recount text translation as well as figuring out the causes of those errors. The subjects of this research were the first-grade students of SMAN 1 Pringsewu in the academic year 2020/2021. This research adopted a descriptive qualitative method by using a translation task and questionnaire as the instruments. The results revealed that the students committed all error types in terms of Communicative Effect Taxonomy: global error and local error. Local errors were more dominating than global errors. The possible causes of those errors were problems in the target language, mother-tongue interference, lack of eagerness to learn the target language, lack of confidence, and the absence of error feedback from the teacher. This suggests that the student’s knowledge of English grammar was still low. Therefore, the English teacher is expected to solve it by providing appropriate teaching methods and materials to minimize the errors. Keywords: Error Analysis, Communicative Effect Taxonomy, Translation

There were two instruments; the first test was morphological awareness test adapted from McBride-Chang et al. (2005) and Zakaria (2008) and the second test was writing a recount text test for measuring the students’ accuracy in writing. The data were analyzed by using Pearson Product Moment Correlation in SPSS version 25. The result of the correlation analysis showed there was a significant correlation between students’ morphological awareness and their accuracy in writing recount text with coefficient correlation was higher than the critical value (0.798>0.297) at significant level .01. It means that the H1 is accepted and H0 is rejected. It can be concluded that morphological awareness influenced students’ accuracy.

Reinterpreting Religious Pluralism in QS. al-Baqarah: 62 (A Method of al-Qaraḍâwî’s Interpretation)
Authors: Kudhori Muhammad , Faiq Muhammad , Farhan Ibnu
Published: February 2022

QS. al-Baqarah: 62 by some Muslim scholars is used to justify that adherents of all religions in this world will get salvation and go to paradise. Salvation in the hereafter, according to them, is not required to believe in the Prophet Muhammad. This article aimed to re-examine that interpretation that is contrary to the belief of the majority of Muslims, in which one aspect of faith that will save people is a belief in the messengers, including a belief in the Prophet Muhammad. The reinterpretation of QS. al-Baqarah: 62 in this study employed the interpretation method of Yûsuf al-Qaraḍâwî in his book entitled Kayfa Nata‘âmal Ma‘ al-Qur’ân al-‘Az}îm. This article is a library based-study by using content analysis and descriptive-analytic. The result revealed that QS. al-Baqarah: 62 actually deals with the earlier peoples before the Prophet Muhammad. Those who believe in Allah and the Last Day and do good deeds are promised a reward from Allah SWT

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice. As of 2017, a functional EHRA (Evaluated Heart valves, Rheumatic or Artificial) categorization was proposed to replace the terms valvular and non-valvular AF. In our country, despite the incidence of rheumatic valve heart disease, studies on this new categorization are scarce Objective: to assess the clinical profile of patients (pts) with AF, using the EHRA categorization as a parameter. Methods: this is a prospective, observational and cross-sectional study with 475 pts with AF from a university institution. Clinical and laboratory evaluations were carried out, as well as the calculation of risk scores for embolism, bleeding and renal function. Statistical analysis was performed by non-parametric tests, in addition to the chi-square test. Results: the pts were divided into 3 groups, according to the EHRA categorization: EHRA 1, with 144 pts, with mitral stenosis or mechanical prosthesis; EHRA 2, with 46 pts with other valvular heart diseases; and EHRA 3, with 285 pts, without valvular heart disease. Mean ages were 51.5; 57.6 and 62.9 years, respectively (p<0.0001). The proportions of women were 75%; 52.1% and 40.7% (p<0.0001). The presentation of the AF was permanent in 68.1%; 60.9%; 52.3% of pts (p=0.008) and 86.0%; 47.8% and 53.3% of pts were using oral anticoagulants, respectively (p<0.0001). The means of left ventricular ejection fraction were 0.58; 0.57 and 0.46; of left atrium were 55.9; 52.5 and 48.1 mm; ATRIA score of 1.4; 1.3 and 2.1; and the glomerular filtration rate of 91.7; 91.1 and 75.0 mL/min/1.73m², respectively (p<0.0001). There was no difference among groups regarding blood pressure and heart rate at study entry and regarding the history of embolism. Conclusions: pts from the EHRA 1 categorization were younger, with a higher proportion of women, permanent AF and use of oral anticoagulants. Systolic dysfunction predominated in those without valve disease, who also had a higher bleeding score and greater impairment of renal function.

Among the potential benefits of probiotic lactic acid bacteria (LAB) is their practical use for biopreservation of foods, fungal decontamination, and novel biotherapy. A number of ready to eat foods hawked in streets of Nigeria such as garri are prone to contamination by mycotoxin-producing fungi. In this study the inhibitory effect of lactic acid bacteria (LAB) (sourced from local foods (nono and kunun- zaki)) and their bacteriocins-derivatives on aflatoxin B1 -producing Aspergelius flavus was conducted. Out of the five LAB isolates screened three (two strains of Lactococcus and one of Pediococcus sp had high indices of probiotic potentials and bacteriocins extracts were obtained from them and used for the inhibition study. Fourty samples of garri sold in Jos metropolis were screened for A. flavus and their abilities to produce Aflatoxin B1 using the Coconut Extract Agar (CEA) and Ammonia Vapour Test (AVP) methods. The three most probiotic LAB and their respective crude baterioncin extracts were used to test for their inhibitory effect on aflatoxin producing A. flavus isolates. The results of the study showed that while only 17 samples (42.50%) had A. flavus in them, only three of the fungi ((17.65%) demonstrated capacity to produce Aflatoxin B1, making (7.5% of the total number of garri samples that had aflatoxin-producing A. flavus. The inhibition of fungal growth by LAB and bacteriocins was dose dependent. At an inoculum concentration of 1 ml, Pediococcus sp had the highest mean zone of inhibition of 43.0 mm followed by Lactococcus sp (Strain LAC20G with radial diameter 38.0mm and Lactococcus sp (LAC20G) which had a radial diameter of 29.3mm respectively. The results of the study portend that the growth of aflatoxin producing Aspergillus flavus in ready to eat foods such as garri could be prevented by application of appropriate dosages of bacteriocins extracts from lactic acid bacteria.
