Masalah anak pendek (stunting) merupakan salah satu permasalahan gizi yang dihadapi di dunia, khususnya di negara miskin dan berkembang. Stunting menjadi permasalahan karena berhubungan dengan meningkatnya risiko terjadinya kesakitan dan kematian, perkembangan otak suboptimal sehingga perkembangan motorik terlambat dan terhambatnya pertumbuhan mental. Stunting merupakan bentuk kegagalan pertumbuhan (growth faltering) akibat akumulasi ketidakcukupan nutrisi yang berlangsung mulai dari kehamilan sampai usia 24 bulan. Keadaan ini di perparah dengan tidak terimbanginya kejar tumbuh (catch up growth) yang optimal. Analisa temuan diuraikan ke bentuk kualitatif deskriftif, selanjutnya peneliti membina hubungan baik dengan responden, menggali informasi akurat, berinteraksi lansung dengan responden. Kriteria responden yang dipilih adalah keluarga yang memiliki anak usia 6 bulan sampai 5 tahun. Sedangkan informan sebanyak 3 orang terdiri dari Kepala Desa, Bidan Desa dan Kader Posyandu. Adapun kesimpulan hasil penelitian faktor penyebab dan resiko terjadinya anak pendek (stunting) yaitu: 1) Genetika dan tidak ada kaitannya dengan masalah kesehatan. Kenyataannya faktor genetika memiliki pengaruh kecil terhadap kondisi kesehatan seseorang dibandingkan dengan faktor gizi, lingkungan dan pelayanan kesehatan. 2) Masalah gizi kronis akibat kurangnya asupan gizi dalam jangka waktu panjang sehingga mengakibatkan terganggunya pertumbuhan pada anak menjadi salah satu penyebab tinggi badan anak terhambat, sehingga lebih rendah dibandingkan anak-anak seusianya. 3) Pengetahuan ibu rendah, pola asuh yang salah, 4) Pelayanan kesehatan yang tidak memadai (Unicef, 1990). 5) Lingkungan sanitasi hygiene yang buruk. 6) Status sosial ekonomi rendah, pendidikan keluarga terutama pendidikan ibu rendah. Hasil penelitian diharapkan dapat menjadi referensi untuk mencengah dan menurunkan faktor resiko stunting di indonesia khususnya di desa Singali.

Abstract
the young Polish anthropologist Stanisław Poniatowski undertook fieldwork in the Russian Far East in summer 1914. He collected almost five hundred various artifacts (objects, photographs, anthropometric measurement forms, etc.) and linguistic material from the local Nanai and Udege communities along the Amur River. The outbreak of World War I changed Poniatowski's plans and caused the separation (fragmentation) of his original collections, now housed at the Polish Ethnological Society in Wrocław, Poland and at the Smithsonian Institution in Washington, DC in the US. The article describes a new multistep effort to digitally “reunite” Poniatowski's collections and convert them into a cultural resource for researchers, museum specialists, and Indigenous communities for heritage and language preservation.

Published: February 2025

Background: Cereals are the most promising raw material for producing functional fermented drinks. Buckwheat possesses a unique chemical composition, high nutritional value, and significant physiological activity. However, cereals lack easily digestible sugars and nitrogen compounds for lactic acid bacteria.
Objective: The study focused on determining whether enzymatic hydrolysis of buckwheat flour can provide a cereal base with soluble sugars and free amino nitrogen to support the rapid growth of lactic acid bacteria and improve the sensory characteristics of fermented products.
Methods: The grain base was obtained from buckwheat groats. The groats were ground into flour. The granulometric analysis of the flour was conducted using a laser analyzer. Flour samples with different particle sizes were hydrolyzed with α-amylase, protease, and glucoamylase. The hydrolysis temperature was selected based on the temperature at which the viscosity of the flour-water mixture reached its maximum. The hydrolysates' solids, sugars, and free amino nitrogen were analyzed using refractometry, HPLC, and spectrophotometry. The buckwheat bases were fermented with L. acidophilus and L. plantarum. The number of lactic acid microorganisms in the fermented bases was determined by the plate count method on MRS agar. Sensory properties (taste, aroma, and texture) were evaluated using a developed 5-point scale.
Results: The study found that hydrolysis of buckwheat flour using α-amylase, protease, and glucoamylase produced a cereal base with 19.15±0.05 g/L glucose, 29.54±0.06 g/L maltose, and 104.72±0.15 mg/100 g of free amino nitrogen. The biomodification resulted in changes to the cereal base composition, favorable for developing lactic acid bacteria cultures. During fermentation of the biomodified base with L. acidophilus, a pH level of 4.5 ± 0.1, a cell count of 10⁸ CFU/g, and high taste and aroma scores were achieved within 5 hours. For L. plantarum, the changes ensured a pH of 4.5 ± 0.1 and a cell count of 10⁷ CFU/g after 7 hours, but lactic fermentation's characteristic taste and aroma were not pronounced.
Conclusion: The buckwheat flour was processed by grinding groats and using enzymatic hydrolysis with α-amylase, protease, and glucoamylase, resulting in a cereal base with a promising composition for the following fermentation. Additionally, the approach offers a model for processing other cereals, contributing to developing alternative plant-based fermented beverages with enhanced functional and sensory properties.
Keywords: buckwheat flour, cereal-based fermented beverage, dairy alternatives, enzymatic hydrolysis, lactic acid bacteria, fermentation.
Observation of Prethermalization in Weakly Nonintegrable Unitary Maps
Authors: Zhang Xiaodong , Lando Gabriel M. , Dietz Barbara , Flach Sergej 
Published: February 2025

We investigate prethermalization by studying the statistical properties of the time-dependent largest Lyapunov exponent \(\Lambda(t)\) for unitary-circuit maps upon approaching integrability. We follow the evolution of trajectories for different initial conditions and compute the mean \(\mu(t)\) and standard deviation \(\sigma(t)\) of \(\Lambda(t)\). Thermalization implies a temporal decay \(\sigma \sim t^{-1/2}\) at a converged finite value of \(\mu\). We report prethermalization plateaus that persist for long times where both \(\mu\) and \(\sigma\) appear to have converged to finite values, seemingly implying differing saturated Lyapunov exponent values for different trajectories. The lifetime of such plateaus furnishes a novel time scale characterizing the thermalization dynamics of many-body systems close to integrability. We also find that the plateaus converge to their respective thermal values for long enough times.
Unification of the Fluid Flow Field, the Electromagnetic Field-Strength Tensors, and the Field Dynamic Equations
Authors: Wang Shisheng 
Published: February 2025

Either mechanical waves or electromagnetic waves propagate in space at a finite speed. The wave propagation speed and particle flow velocity form a four-vector. Using the four-vector, we can obtain the fluid flow field and the electromagnetic field strength tensor. Both tensors share the same mathematical structure and can be unified into a single mathematical frame. The field dynamic equations, either for fluid flow or for the charged particle motions, are a combination of the translational and the rotational motion. The rotational motion behaves as wave properties. The strength tensor contraction (inner product) forms a hypersurface. It is an indefinite quadratic form (saddle-shaped surface) that can take positive or negative values to reveal the dominating moving types. The electromagnetic waves are located at the saddle points, and the strength tensor for electromagnetic waves is zero. In general, the motion in the field obeys the weak form of Newton’s action and reaction law, namely, the field has an induced secondary flow, due to the interactions between vorticity and velocity for fluid flow or the magnetic field and the charge flow for the electromagnetic field. It is found that this approach is equivalent to the Euler-Lagrangian method, which is expressed by \(D_t\vec{p} = \nabla\mathcal{L}\)_._ Both methods will produce the same field dynamic equations.
Fixed-Sized Clusters k-Means

Published: February 2025

We present a \(k\)-means-based clustering algorithm, which optimizes the mean square error, for given cluster sizes. A straightforward application is balanced clustering, where the sizes of each cluster are equal. In the \(k\)-means assignment phase, the algorithm solves an assignment problem using the Hungarian algorithm. This makes the assignment phase time complexity \(O(n^3)\). This enables clustering of datasets of size more than 5000 points.

Introduction. The use of the method of mechanochemical synthesis to obtain solid dispersions (SD) of albendazole (ALB) has allowed increasing its anthelmintic activity and bioavailability, as well as reducing its toxicity, and therefore the issue of developing the composition and technology of an affordable domestic drug based on SD of ALB in a rational dosage form (DF) is relevant.Aim. Development and pharmacotechnological study of suspension for oral administration based on TD ALB obtained by mechanochemical solid-phase synthesis.Materials and methods. The objects of the study were ALB substance (ALB), licorice dry extract (LE) and their SD obtained by mechanochemical solid-phase synthesis in a mass ratio of 1 : 5, 1 : 10 and 1 : 20, with a mechanical treatment duration of 2 hours, 8 hours and 16 hours. Substances approved for medical use are used as excipients. The study of the solubility of ALB from SD was evaluated by the content of ALB in an aqueous medium using high-performance liquid chromatography. The study of the properties of SD and the obtained DF was carried out in accordance with the requirements of the State Pharmacopoeia of the Russian Federation (SP RF) XV edition.Results and discussion. The technological properties of SD do not change significantly depending on the mass ratio of medicinal substance (MS) to the carrier and the time of their machining, as a result of which the determining factor in choosing the optimal SD for the development of a DF is the value of the solubility of ALB in water. The use of the wet granulation method and the addition of a filler, stabilizer and preservative to the SD make it possible to obtain powders for the preparation of a suspension with satisfactory technological characteristics.Conclusion. During the study, the technological characteristics of SD ALB with LE obtained by mechanochemical solid-phase synthesis were studied, and the optimal SD was determined from the point of view of the highest solubility of ALB in water. Excipients were selected, the composition of the suspension restored from SD ALB granules with optimal technological parameters was developed. Pharmacotechnological studies of suspensions based on SD ALB were conducted.

Published: February 2025

IntroductionEnvironmental DNA (eDNA) metabarcoding of water is increasingly being used to monitor coastal biodiversity shifts. However, we have limited knowledge of whether samples collected during discreet temporal periods depict holistic ecosystem changes over longer time spans.MethodsHere, we show how eDNA community structure varies across repeated sampling events at different temporal scales ranging from years to months to days at an Arctic coastal site, Churchill (Canada), using metabarcoding analyses of water eDNA samples with four universal primer pairs (two primers in COI and two in the 18S rRNA).ResultsDaily variations were highly dynamic and less structured, likely due to the stochastic nature of estuarine ecosystems, but there was a clear annual consistency in eDNA communities with a high proportion of shared taxa between years. However, monthly sampling was the most efficient for capturing holistic biodiversity.DiscussionWe provide recommendations for optimal eDNA metabarcoding sampling design based on our observations. The study underscores the importance of understanding biological and physical factors altering eDNA detection to improve the efficiency of detecting and interpreting long-term eDNA changes.

Published: February 2025

IntroductionTo study the composition and succession of bacterial and fungal communities during the fermentation of cigar filler leaves with varying initial water contents, high-throughput sequencing technology was used to sequence the bacterial 16SrRNA genes and fungal ITS1 genes from cigar tobacco leaf samples. This was followed by analyses of microbial α-diversity, microbial community structure, and bacterial function prediction based on the sequencing data.ResultsThe diversity and richness of microbial communities decreased over time during fermentation under different water content conditions. Among the 18 cigar filler leaf samples, the predominant phyla identified were Proteobacteria, Firmicutes, Actinobacteria, Ascomycota, and Basidiomycota, with the leading genera being Staphylococcus, Sphingomonas, Methylobacterium-Methylorubrum, Pseudomonas, and Humicola. Functional predictions for the bacteria revealed their primary involvement in carbohydrate, lipid, and amino acid metabolism.ConclusionThe initial water content of cigar tobacco leaves influenced the structure and relative abundance of microbial communities during fermentation. While the microbial community exhibited a similar structural composition, there were notable differences in relative abundance. The functional prediction results from PICRUSt indicated that the differences in predicted functional species among samples were minimal, whereas the variations in the abundance of functional species were more pronounced across different fermentation stages and initial water contents.
