Ǭ-representation of Real Numbers as a Generalization of Cantor Numeral Systems
Authors: Pratsiovytyi Mykola , Bondarenko Olha , Ratushniak Sofiia , Franchuk Kateryna
Published: March 2023

We consider generalization of Cantor numeral system, which is determined by the sequence of bases (sn), 1 < sn ∈ N, and the sequence of alphabets An = {0, 1, ..., sn − 1}:[0; 1] ∋ x = ∞∑ n=1 αn/s1s2...sn, αn ∈ An,the so-called Ǭ-representation. It is defined by an infinite “matrix” ||qik||, where i ∈ Ai, k ∈ N, having the properties0 < qik < 1, mk ∑ i=0 qik = 1, k ∈ N, ∞∏ n=1 max i {qik} = 0,namely[0; 1] ∋ x = ai11 + ∞∑ k=2 [aikk k−1 ∏ j=1 qij (x)j ] ≡ Δi1i2...ik..., where ainn = in−1 ∑ j=0 qjn, in ∈ An, n ∈ N.The applications of this representation of numbers in the metric theory of numbers, the theory of distributions of random variables, the theory of locally complicated functions, and fractal analysis are studied.For the set C[Ǭ; Vn] = {x : x = Δα1...αn..., αn ∈ Vn ⊂ An}, we study its topological and metric structure and derive a formula for calculating its Lebesgue measure:λ(C) = ∞∏ n=1 λ(Fn) / λ(Fn−1) = ∞∏ n=1 (1 − λ(Fn) / λ(Fn−1)),where F0 = [0; 1], Fn is the union of Ǭ-cylinders of rank n, such that there are points of the set C among their interior points of the set C, Fn ≡ Fn−1 \ Fn.A criterion and some sufficient conditions for this set to be a set of zero measure are found. Under additional conditions on the “matrix” ||qik||, the normal property for Ǭ-representation of numbers is found ((i.e., almost all in the sense of Lebesgue measure numbers have this property). The obtained results are used to establish the Lebesgue structure and the type of distribution of a random variable whose digits of Ǭ-representation are independent random variables. It is proved that the digits of the Ǭ-representation of a random variable uniformly distributed on [0; 1] are independent, and their distribution is given.If the cardinalities of the alphabets are finite and the elements of the “matrix” ||qik|| are bounded away from zero, it is proved that to calculate the Hausdorff-Besicovitch fractal dimension of subsets of the segment [0; 1], it is sufficient to cover them with Ǭ-cylinders: Δc1...cm = {x : x = Deltac1...cki1...in..., in ∈ ∈ Ak+n}.For inversor of digits of Ǭ-representation of numbers, that is, the function defined by equality I(x = = Δi1...in...) = Δ[m1−i1]...[mn−in]..., mn ≡ sn − 1 it is proved its continuity, strict monotonicity, and for certain cases, its singularity (the equality of the derivative to zero almost everywhere in the sense of the Lebesgue measure).

Discurso narrativo social de poder en anuncios indicadores como dispositivos de seguridad globales en el espacio público de México
Authors: Lozano Castro Rebeca I.
Published: March 2023

Esta reflexión crítica pone en diálogo la globalización con impacto en México durante el año 2000 al 2010, leída a partir de anuncios indicadores implementados en la vía pública como parte del discurso narrativo social. La muestra de casos particulares de anuncios gráficos-idendicativos revisados supone un grupo de comercios locales y multinacionales que mantuvieron un proceso emancipatorio, lo que expone tangencialmente el poder político-económico temporal y espacial en ese país. Precisamente, la acumulación de elementos gráficos comunicacionales alteró el estilo de vida en esa sociedad y su paisaje urbano. De ahí que, la revisión de este estudio con enfoque histórico permitió la diferenciación de rasgos de transformación y permanencia de los objetos de diseño, con categorías y características observadas y narradas como representaciones materializadas en respuesta del impacto de globalización. Las conclusiones obtenidas exponen los diseños como elementos comunicacionales narradores de poderío ejercido político-social que problematizan el poder como factor determinante del espacio urbano.

Keberadaan sampah di tengah masyarakat terus meningkat, terutama jumlah sampah anorganik yang sulit terurai dan dapat mengakibatkan kerusakan lingkungan. Sebagai khalifah di bumi hendaknya kita senantiasa menjaga lingkungan sesuai dengan tuntunan syariah yang dibahas dalam fiqih lingkungan. Salah satu cara yang cukup tepat untuk mitigasi dampak buruk dari penumpukan sampah anorganik adalah dengan menabungkan sampah tersebut ke bank sampah. Sampah anorganik yang tadinya tidak memiliki nilai ekonomis dan justru dapat merusak lingkungan akan diolah di bank sampah menjadi berbagai kerajinan dan dikumpulkan untuk didaur ulang secara masal di pabrik. Solusi menabung sampah rumah tangga di bank sampah kurang mendapat perhatian oleh masyarakat. Sehingga pengabdian ini bertujuan untuk melakukan penyuluhan dan sosialisasi bagi ibu-ibu PKK untuk menabung sampah rumah tangga di bank sampah. Lokasi sosiasialisasi berada di desa Rejodani, Umbulmartani, Ngemplak, Sleman, Yogyakarta. Program pengabdian ini dirancang menggunakan metode sosiaslisasi dan diskusi mengenai bank sampah.
Neural Induction, Embryogenesis, and Tumorigenesis
Authors: Cao Ying
Published: March 2023

Characterization of cancer cells and neural stem cells indicates that tumorigenicity and pluripotency are coupled cell properties determined by neural stemness, and tumorigenesis represents a process of progressive loss of original cell identity and gain of neural stemness. This reminds of a most fundamental process required for the development of the nervous system and body axis during embryogenesis, i.e., embryonic neural induction. Neural induction is that, in response to extracellular signals that are secreted by the Spemann-Mangold organizer in amphibians or the node in mammals and inhibit epidermal fate in ectoderm, the ectodermal cells lose their epidermal fate and assume the neural default fate and consequently, turn into neuroectodermal cells. They further differentiate into the nervous system and also some non-neural cells via interaction with adjacent tissues. Failure in neural induction leads to failure of embryogenesis, and ectopic neural induction due to ectopic organizer or node activity or activation of embryonic neural genes causes a formation of secondary body axis or a conjoined twin. During tumorigenesis, cells progressively lose their original cell identity and gain of neural stemness, and consequently, gain of tumorigenicity and pluripotency, due to various intra-/extracellular insults in cells of a postnatal animal. Tumorigenic cells can be induced to differentiation into normal cells and integrate into normal embryonic development within an embryo. However, they form tumors and cannot integrate into animal tissues/organs in a postnatal animal because of lack of embryonic inducing signals. Combination of studies of developmental and cancer biology indicates that neural induction drives embryogenesis in gastrulating embryos but a similar process drives tumorigenesis in a postnatal animal. Tumorigenicity is the manifestation of aberrant occurrence of pluripotent state in a postnatal animal. Pluripotency and tumorigenicity are both but different manifestations of neural stemness in pre- and postnatal stage, respectively, of animal life. The unique property of neural stemness is derived from the evolutionary advantage of neural genes and the neural-biased state of the last common unicellular ancestors of metazoan. Based on these findings, I discuss about some confusion in cancer research, propose to distinguish the causality and associations and discriminate causal and supporting factors involved in tumorigenesis, and suggest revisiting the focus of cancer research.
Quantum Central Limit Theorems, Emergence of Classicality and Time-dependent Differential Entropy
Authors: Kieu Tien D
Published: March 2023

We derive some Quantum Central Limit Theorems for expectation values of macroscopically

coarse-grained observables, which are functions of coarse-grained hermitean operators consisting

of non-commuting variables. Thanks to the hermicity constraints, we obtain positive-definite dis-

tribution for the expectation values of observables. These probability distributions open some

pathway for an emergence of classical behaviours in the limit of innitely large number of identical

and non-interacting quantum constituents. This is in contradistinction to other mechanisms of

classicality emergence due to environmental decoherence and consistent histories. The probabil-

ity distributions so derived also enable us to evaluate the nontrivial time-dependence of certain

differential entropies.
A Multivariate Approach to Determining and Predicting the Internal Postharvest Quality of Hass Avocado

Published: March 2023

There is immense variability in the postharvest quality of Hass avocados. However, there is a lack of knowledge to guaranteeing the robustness of fruit with consistent quality. The aims of this work were to develop a multivariate methodology for evaluating the postharvest quality of avocado and to determine predictive quality markers to manage fruit quality. Fruit samples produced under different nutrient management, elevation, date-to-harvest, and growing-cycle conditions were analyzed. The results highlighted soil and weather differences among orchards. Nutrient management practices based on index balancing in some samples increased both productivity and the fruit size. High variability was observed in the dry matter related to the age of the fruit at harvest. Ripening heterogeneity was very large in low-elevation orchards where the fruit was picked relatively early. High flesh mineral contents delayed fruit ripening. At low growing temperatures, more oleic and linoleic acids were present in fruits. The sensory texture and taste descriptors were affected by the fruit age and related to the flesh composition. Logistic, PLS-DA, and biplot models effectively represented the variabilities in the ripening pattern, composition, and sensory profile of avocado fruits and allowed the samples to be grouped according to the internal fruit quality.

Authors: Gustiani Ria , Kartini Farida
Published: March 2023

Background: Postpartum haemorrhage in general is defined as blood loss from the body in the amount of 500 ml after vaginal delivery or 1000 ml after cesarian section. Every year it is estimated that there are 140.000 mother’s death caused by PPH or every 4 minutes 1 death occurs worldwide caused by PPH.  According to WHO 99% of all maternal deaths occur in developing countries due to postpartum hemorrhage. Based on data obtained in 2020, the MMR in Indonesia is 305 per 100,000 live births.

Purpose: to find out the factors affecting haemorrhage occurrence on postpartum mother based on the results of previous research.

Method: Scoping review using databases: Google Schoolar, PubMed, and ProQuest. The keywords used in the literature search are “Factor”, “Postpartum haemorrhage”, “maternity”. The searching results were 7 articles which fulfilled the criteria. The 7 articles then were analyzed by using The Joana Briggs Institute and synthesis method using PEOS modification

Results: Out of 99 articles with relevant title and abstract, obtained 7 articles which fulfilled the inclusion and exclusion criteria. Four factors were found, which are; perineal tear, anemia, placental complications, and uterine atony which affects the haemorrhage on postpartum mother.
Conclusion: There are four most frequent factors occurring which affect the occurrence of postpartum haemorrhage namely birth canal tear, anemia factor, placental complication, and uterine atony. Those factors can cause and continuously increase haemorrhage which can lead to maternal mortality rate.
