Electrolyte engineering is crucial for improving battery performance, particularly for lithium metal batteries. Recent advances in electrolytes have greatly improved cyclability by enhancing electrochemical stability at the electrode interfaces, but concurrently achieving high ionic conductivity has remained challenging. Here we report an electrolyte design strategy for enhanced lithium metal batteries by increasing the molecular diversity in electrolytes, which essentially leads to high entropy electrolytes (HEEs). We find that in weakly solvating electrolytes, the entropy effect reduces ion clustering while preserving the characteristic anion-rich solvation structures, which is characterized by synchrotron-based X-ray scattering and molecular dynamics simulations. Electrolytes with smaller-sized clusters exhibit a 2-fold improvement in ionic conductivity compared to conventional weakly-solvating electrolytes, enabling stable cycling at high current densities up to 2C (6.2 mA cm-2) in anode-free LiNi0.6Mn0.2Co0.2 (NMC622) || Cu pouch cells. The efficacy of the design strategy is verified by performance improvements in three disparate weakly solvating electrolyte systems.
From Particle-in-a-Box Thought Experiment to a Complete Quantum Theory?
Authors: Chen Jixin
Published: May 2023

The Schrödinger equation provides wavefunctions that describe the behavior of atoms, molecules, and materials, but constructing these wavefunctions by basis sets from fitting experimental data has rendered quantum chemistry predominantly empirical. The computational intensity of this process arises partly from the requirement to integrate wavefunctions across space to calculate energy levels. In this manuscript, a novel equation is proposed that significantly accelerates the computation of energy levels compared to classical quantum mechanics. Leveraging the first law of thermodynamics, which dictates that an equilibrium system maintains its total energy, an energy density function is derived that exhibits spatial uniformity and eliminates the need for normalization and renormalization. Consequently, the energy calculation no longer necessitates the integration of the entire wavefunction and transforms the second-order differential equation into a first-order counterpart. This new equation draws inspiration from the energy conservation method employed in solving classical mechanics problems like the pendulum. Remarkably, it successfully quantizes the energy levels of classical quantum systems, including the particle-in-a-box thought experiment, harmonic oscillator, and free spin, relying on simple rules such as momentum conservation. Therefore, it holds the potential to fit experimental data and reduce computational costs in modern quantum chemistry calculations.
iupacGPT: IUPAC-based large-scale molecular pre-trained model for property prediction and molecule generation

Published: May 2023

The IUPAC (International Union of Pure and Applied Chemistry) nomenclature is a globally recognized unique naming system which assigns names to chemical compounds. As a form of molecular representation closest to natural language, it allows to estimate molecular data in a large-scale pre-trained paradigm by employing machine learning approaches for natural language processing (NLP). Although, SMILES is currently popular molecular representation used by most generative models, different molecular representation is suitable for different scenarios, and considering the advantages of IUPAC in terms of readability, it becomes meaningful to explore the difference of these two different molecular representations for molecular generation and regression/classification tasks. In this paper, we attempt to adapt the capabilities of transformer to a large IUPAC corpus by constructing a GPT-2-like language model named iupacGPT. For each task in addition to the molecular generation, we freeze model parameters and attach trainable lightweight networks to fine tune. The results show that pre-trained iupacGPT can capture general knowledge that can be successfully transferred to the downstream tasks such as molecule generation and binary classification and property regression prediction. What’s more, with a same setup, iupacGPT outperforms the model smilesGPT in term of the downstream tasks. Overall, transformer-like language models pretrained on IUPAC corpora are promising alternatives that obtain more intuitive in terms of interpretability and semantic level than on SMILES corpora, and scale well with the pretraining data size. https://github.com/AspirinCode/iupacGPT

Diabetes mellitus remains a major global health burden and great attention is directed at natural therapeutics. This systematic review aimed to evaluate the potential of flavonoids as antidiabetic agents through their ability to inhibit α-amylase and α-glucosidase, two key starch digestive enzymes. Six scientific databases were queried up until August 21, 2022, for in vitro studies reporting the IC50 results of purified flavonoids on α-amylase or α-glucosidase, along with the respective data of acarbose control. A total of 339 articles were assessed as eligible and subjected to the data extraction process, resulting in 1643 retrieved structures, 177 compounds of which showed both inhibitions against α-amylase and α-glucosidase. Quality assessment was conducted following a modified CONSORT checklist. The structureactivity relationships revealed that a double bond C2=C3 and a keto group C4=O is essential for simultaneous inhibition. The hydroxyl group at C3 is favourable for α-glucosidase inhibition but detrimental to the effect against α-amylase. Further notable features which affect α-glucosidase and α-amylase inhibition were also discussed. Several limitations were considered, including the inconsistency among included studies, language restriction, and the contemporaneity of the review. In conclusion, the systematic review has summarized some crucial findings in the investigation of flavonoids as dual-target inhibitors against α-glucosidase and α-amylase and proposed several orientations for future research.

The elegant architectures of nonplanar π-systems, such as fullerene and corannulene, exhibit distinctive functionalities that have played a significant role in advancing science and technology. The current approach to synthesizing nonplanar π-systems heavily relies on the stepwise formation of bonds between their constituent fragments, which is known as the bottom-up approach. The limited number of synthetic pathways to nonplanar π-systems inevitably results in impractical molecular frameworks. Herein, we demonstrate that a constructive destruction approach, based on the oxidative cleavage of internal double bonds of dibenzo[g,p]chrysene that immediately produces eightphenone: the first readily available figure-eight molecule. Eightphenone adopts a D2-symmetric structure with excellent configurational stability and is a highly efficient emitter of circularly polarized phosphorescence. The oxidative cleavage of internal double bonds is also applicable to larger nanographene molecules, resulting in unprecedented structures with multiple figure-eight units. This study introduces the concept of constructive destruction as an alternative to conventional bottom-up approaches, paving the way for the design of new materials.
Simultaneous Electrochemical Exfoliation and Functionalization of 2H-MoS2
Authors: Zhuo Yuling , Kinloch Ian , Bissett Mark
Published: May 2023

MoS2 is a promising semiconducting material that has been widely studied for applications in catalysis and energy storage. The covalent chemical functionalization of MoS2 can be used to tune the optoelectronic and chemical properties of MoS2 for different applications. However, 2H-MoS2 is typically chemically inert and difficult to functionalize directly and thus requires pre-treatments such as a phase transition to 1T-MoS2 or argon plasma bombardment to introduce reactive defects. Apart from being inefficient and inconvenient, these methods can cause a degradation of the desirable properties and introduce unwanted defects. Here, we report a facile and scalable procedure of fabricating functionalized thin (~4 nm) MoS2 layers. We demonstrate that 2H-MoS2 can be simultaneously electrochemically exfoliated and functionalized. The aryl diazonium salts used for functionalization have not only been successfully grafted onto the 2H-MoS2, as verified by X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy, but also aid the exfoliation. Electrochemical characterization of MoS2 supercapacitors revealed that the specific capacitance of electrodes produced using this material was increased by 25% when functionalized. This electrochemical functionalization technique could possibly be extended to other types of transition metal dichalcogenides (TMDs), which are also chemically inert, with different functional species to adjust to specific applications.
Accurate Electronic and Optical Properties of Organic Doublet Radicals Using Machine Learned Range-Separated Functionals

Published: May 2023

Luminescent organic semiconducting doublet-spin radicals are unique and emergent optical materials because their fluorescent quantum yields (Φfl) are not compromised by spin-flipping intersystem crossing (ISC) into any dark high-spin states. The multiconfiguration nature of these radicals challenges their electronic structure calculations in the framework of single-reference density functional theory (DFT) and introduces room for method improvement. In the present study, we extend our earlier development of ML-ωPBE, a range-separated hybrid (RSH) exchange−correlation (XC) functional constructed using the stacked ensemble machine learning (SEML) algorithm, from closed-shell organic semiconducting molecules to doublet-spin organic semiconducting radicals. We assess its performance for a new test set of 64 radicals from five categories based on the original training set of 3,926 molecules. Interestingly, ML-ωPBE agrees with the first-principles OT-ωPBE functional regarding the molecule-dependent range-separation parameter (ω), with a small mean absolute error (MAE) of 0.0197 a0−1 but saves the computational cost by 2.46 orders of magnitude. This result demonstrates outstanding domain adaptation capacity of ML-ωPBE among various organic semiconducting species. To further assess the predictive power of ML-ωPBE, we also compare its performance on absorption and fluorescence energies (Eabs and Efl) evaluated using time-dependent DFT (TDDFT) with nine conventional functionals. For most radicals, ML-ωPBE reproduces experimental measurements of Eabs and Efl with small MAEs of 0.222 and 0.121 eV, only marginally different from OT-ωPBE. Our work illustrates a successful extension of the SEML framework from closed-shell molecules to open-shell radicals and will open the venue for calculating optical properties using single-reference TDDFT.

An attempt to preserve the knee joint in a patient on hemodialysis with stage IV lower limb ischemia with a high risk of thrombotic and hemorrhagic complications is presented. Multifocal atherosclerosis and extensive occlusion of the arteries of the lower leg ruled out the technical possibility of revascularization. The patient refused the proposed hip amputation. An attempt was made to perform amputation at the level of the lower leg. Required therapy aimed at the treatment and prevention of thrombotic complications, and optimization of microcirculation in the ischemic limb. For this purpose, a prolonged blockade of the sciatic and femoral nerves, combined anticoagulant therapy, and treatment with alprostadil were performed. Therapy with antithrombotic and vasoactive drugs was not effective and was complicated by the state of persistent hypocoagulation with an episode of bleeding. Amputation of the limb at the level of the thigh was performed according to vital indications after correction of hypocoagulation. The lack of clinical recommendations on anticoagulant therapy for critical lower limb ischemia in patients with stage 5 chronic kidney disease requires an individual approach to the choice of antithrombotic drugs and their doses, monitoring the state of blood coagulation using an integral method for assessing the hemostasis system thromboelastography.

In recent years, the attention of scientists has been actively focused on studying the role of endocan as a biological marker of endothelial dysfunction in cardiovascular diseases. Until recent years, endocan has been studied in acute kidney injury, chronic kidney disease, and renal replacement therapy. Endocan, formerly known as endothelial cell-specific molecule-1, is a soluble dermatan sulfate proteoglycan expressed and secreted into the circulation from endothelial cells. Currently available studies demonstrate the diagnostic and prognostic value of endocan evaluation in cardiovascular pathology. It is expected that further scientific and clinical studies will demonstrate the possibilities of using endocan as an additional laboratory tool for diagnosing and assessing the prognosis in patients with a cardiac profile. Drug regulation of endocan concentration and expression may be a promising target for the treatment of cardiac and vascular pathology.

Published: May 2023

For several years, there has been a significant increase in the number of patients diagnosed with cardiac amyloidosis. However, there are still difficulties associated with the diagnosis, identifying its type and further treatment of the disease. The diversity of the clinical symptoms, the absence of pathognomonic symptoms make it difficult to diagnose, which leads to the progression of the disease. Heart involvement is the main cause of morbidity and mortality in systemic amyloidosis, regardless of the underlying pathogenesis of amyloid production, and in most cases amyloid cardiomyopathy is clinically manifested by rapidly progressive symptoms of heart failure. The article presents a clinical case of a patient with a hereditary type of systemic transthyretin amyloidosis with the involvement of heart, kidneys, liver, nervous system, and the identified mutation in the TTR gene (p.Y89F) has not been previously described in the Russian Federation.
Welfare implications of asset pricing facts: should central banks fill gaps or remove volatility?
Authors: Lopez Pierlauro
Published: May 2023

I find that removing consumption volatility is a priority over filling the gap between consumption and its flexible-price counterpart, or inflation targeting, in a model that matches empirical measures of the welfare costs of consumption fluctuations. Nearly 30 years of financial market data suggest sizable welfare costs of fluctuations that can be decomposed into a term structure that is downward-sloping on average, especially during downturns. This evidence offers guidance in selecting a model to study the benefits of macroeconomic stabilization from a structural perspective. The addition of nonlinear external habit formation to a textbook New Keynesian model can rationalize the evidence, and it offers a framework suitable for studying the desirability of removing fluctuations. The model is nearly observationally equivalent in its quantity implications to a standard New Keynesian model with CRRA utility, but the asset pricing and optimal policy implications are dramatically different. In the model, a central bank that minimizes consumption volatility generates welfare improvements relative to an inflation targeting regime that are equivalent to a 25 percent larger consumption stream.
POST-POSTMODERN: ARTS AND TRENDS
Authors: Zahurska Nataliia
Published: May 2023

This article considers post-postmodern arts and trends in their diversity. The starting point of the research is the comparison of postmodern and post-postmodern in the art environment. Postmodern paradoxically limits the redundancy, not allowing sufficient displaying of the special features of an art object. Post-postmodern arts provide a possibility to overcome the lack and danger of events and the self-happening of a human being. Object-oriented ontology (OOO) by Graham Harman, performatism by Raoul Eshelman, metamodernism by Timotheus Vermeulen and Robin van den Akker, digimodernism by Alain Kirby, post-postmodern understanding of architecture by Tom Turner, etc. are intellectual trends, which comprehends peculiarities of postmodern and post-postmodern art in particular. OOO displays, that post-postmodern art is rather theatrical that literal and even post-postmodern literature becomes theatrical. The renouncement from an overestimation of both form and function in art, especially in architecture, allows to designate a weird formalism as an actual art position. Since the article deals with the art of living through, the greatest attention is paid to architecture as an exemplary art. This explains the appeal to works that research architecture, including the theories of architects themselves such as Peter Zumthor or Juhani Palasmaa or creating architectural art objects by writers. On the other hand, post-postmodern writers such as David Foster Wallace or Dave Eggers create theatrical literary works, which are often filmed. Performatism as a direction developing post-millennial generative anthropology is the basis for the researching of generative art as the most unpredictable and close to the spontaneity of living through as a moving to attract objects, including art objects. This article develops this approach by researching of moving from self-performance to self-happening as an art of demeanor, a mode of being. Thus, post-postmodern art in its diversity appears as art a human being living through.

O SISTEMA INTERAMERICANO DE DIREITOS HUMANOS E A PROTEÇÃO DE MINORIAS E DE GRUPOS VULNERÁVEIS
Authors: Santos Lima Sabrina , Hennig Leal Mônia Clarissa
Published: May 2023

A proteção dos direitos humanos ganhou impulso após a Segunda Guerra Mundial, quando os debates sobre o tema se intensificaram e tornou-se perceptível a necessidade de sua concretização. Tanto isso é verdade, que novos organismos internacionais surgiram para atuar nesse sentido, sobressaindo-se, no cenário americano, o Sistema Interamericano de Proteção, composto pela Comissão e pela Corte Interamericana de Direitos Humanos. Os dois órgãos vêm desempenhando importante papel, através de opiniões consultivas, recomendações, promoção de direitos humanos e, também, por meio dos casos contenciosos, julgados pela Corte. Isso se destaca ainda mais quando em jogo a proteção das minorias e dos grupos vulneráveis, os quais, não raras vezes, se veem desamparados no âmbito interno, encontrando refúgio através dos mecanismos internacionais. Dessa forma, exsurge a problemática a ser trabalhada no presente trabalho, qual seja: como se dá a proteção dos grupos em situação de vulnerabilidade pela Corte IDH, a partir da lógica das sentenças estruturantes? Para tanto, utiliza-se o método dedutivo, tendo-se como objetivos desmistificar as entrelinhas existentes entre os dois conceitos (minorias e grupos vulneráveis), abordar a lógica de funcionamento do Sistema Interamericano, bem como analisar a atuação da Corte no que se refere às sentenças estruturantes, consubstanciadas na determinação de implementação de políticas públicas. Conclui-se que a Corte, enquanto guardiã e intérprete autêntica da Convenção Americana, vem adotando uma postura mais ativa ao sentenciar, determinando a implementação de políticas públicas aos Estados, o que reflete diretamente na proteção e garantia dos direitos dos grupos vulneráveis.

SPECTRAL METHOD OF V. A. ILYIN. NON-SELF-ADJOINT OPERATORS. II. ESTIMATES FOR THE RATE OF EQUICONVERGENCE OF SPECTRAL EXPANSIONS
Authors: Lomov Igor
Published: May 2023

This monograph continues the series devoted to the results obtained with the help of V.A. Ilyin spectral method for studying differential operators. The problem of obtaining estimates for the rate of equiconvergence and estimates for the rate of convergence of spectral expansions of functions over systems of root functions of ordinary differential operators of various orders given on a finite interval of the real line or on the entire line is investigated. Convergence and equiconvergence of spectral expansions of functions is considered in various metrics. Equiconvergence theorems make it possible to transfer known results on the convergence or divergence of well-studied series (for example, trigonometric series or series in exponential systems) into spectral expansions in terms of eigenfunctions and associated functions of differential operators. The first theorems of equiconvergence of spectral expansions of functions - the Steklov- Hobson-Haar and Tamarkin-Stone theorems - are given. We present and prove in detail the first theorem containing an estimate for the rate of local equiconvergence of spectral expansions of functions - the Ilyin-Yo theorem, as well as the first theorem containing an estimate of the rate of equiconvergence of spectral expansions of functions on the entire interval. A theorem is formulated and proved that generalizes the classical theorem of F. Riesz (Riesz- Fischer) to biorthogonal systems of functions. This theorem, along with local and non-local mean value formulas, which are given much attention in the book, served as a tool that made it possible to extend the results on estimates of the rate of local equiconvergence to the case of equiconvergence over the entire segment of the operator specification. The book is intended for mathematicians, physicists, applied mathematicians and engineers who are in contact with the spectral theory of differential operators, students and graduate students of mathematical specialties of universities.

Bu çalışmada amaç Türkiye’nin 2005:M1–2023:M1 dönemindeki BİST100 endeksi, altın ve ABD doları getirilerinin enflasyon üzerindeki etkilerini ekonometrik yöntemlerle incelemektir. Bu çerçevede çalışmada Gecikmesi Dağıtılmış Otoregresif sınır testi ile Toda-Yamamoto nedensellik testi kullanılmıştır. Yapılan analizler sonucunda BİST100 getirileri ile ABD doları getirilerinin enflasyon üzerinde hem kısa hem de uzun dönemde etkili oldukları ve bu etkilerin istatistiki açıdan anlamlı olduğu tespit edilmiştir. Fakat altın getirilerinin enflasyon üzerindeki etkisinin hem kısa hem de uzun dönemde istatistiki açıdan anlamsız olduğu tespit edilmiştir. Ekonometrik analizin son aşamasında değişkenlere Toda-Yamamoto nedensellik testi uygulanmıştır. Bu teste göre Türkiye’de enflasyon ile ABD doları getirileri arasında çift yönlü nedensellik ilişkisine rastlanmıştır. Ayrıca ABD doları getirileri ve enflasyondan altın getirilerine doğru, BİST100 getirilerinden ise enflasyona doğru tek yönlü nedensellik ilişkisine rastlanmıştır. Bu çalışmanın sonucunda, yatırımcılar ve portföy yöneticilerinin bu finansal araçlara yatırım yapacakları zaman bu finansal yatırım araçları ile enflasyon arasındaki ilişkinin hareket yönünü göz önünde bulundurmaları tavsiye edilmektedir.

O termo «colonial» desenterra fantasmas relacionados com leituras conexas a memórias, sentimentos de culpa e mágoas ainda incómodas. As narrativas coloniais são sobretudo um louvor à «missão» e à ação colonizadoras, assim como às gentes da metrópole e do território colonial, numa perspetiva de uma «natural» superioridade branca. Este artigo pretende cartografar preconceitos culturais do passado colonial através da análise de narrativas ficcionais sobre Angola e Moçambique, datadas entre os anos 20-60, que permitem um entendimento mais circunstanciado do pensamento e da representação do mundo colonial português do século XX.

For protection against electric shock in electrical equipment, particularly in control or instrument installations in substation equipment, a quality earthing system is required. The earthing system is also affected by soil resistivity with different soil types. In the equipment grounding system, knowledge of the types of electrodes and the type of soil is required. At the Prabumulih substation, Podzolic soil is required to evaluate the stress distribution that happens in the soil in order to reduce Ground Potential Rise (GPR). In addition to obtaining the economic value of the rod electrode type employed. In this study the resistivity value of the podzolic soil type is very decisive so that the resistivity value of the podzolic soil type at the pre-selection substation land is 150 Ωm.

The genetic resources of food plants are an indispensable asset for the formation or improvement of the characteristics of superior varieties. These genetic resources continue to experience erosion due to modern agricultural practices, so they must be preserved through exploration, characterization, and estimation of genetic parameters. This study aims to determine the similarity of traits and genetic parameters of local upland rice varieties. The experiment was conducted at the Sidondo experimental garden, Sidondo Village, Tambubulava District, Sigi Regency, from April to August 2019. The study used a Randomized Block Design with 24 local varieties as the treatment, which was repeated three times so that there were 72 experimental plots. The cluster analysis results showed 3 clusters of grouping varieties, namely one variety for cluster 1, 6 types for cluster 2, and 17 combinations for cluster 3. 10 traits had high coefficients of genetic diversity. The number of seeds per panicle, leaf area, plant height, number of tillers, leaf length, flowering age, and stem diameter are traits with high heritability and genetic progress. The number of productive tillers is a trait with a simple correlation value and a heightened direct effect on yield, so indirect selection can be made to increase upland rice yield.

COVID-19 challenged information exchange globally, including interlibrary loan (ILL). This project explored DOCLINE ILL borrowing data from 15 academic, hospital, and association health sciences libraries before and during the pandemic to understand gaps in ILL coverage. We reviewed aggregate filled and unfilled borrowing data from March to August in 2019 and 2020. We compared these time periods to each other and to system-wide fill rates. We normalized journal titles, added journal price and language, calculated descriptive statistics and odds ratios, and conducted 2-proportion z-tests of differences. In our sample of 14,891 requests, the odds of requests being unfilled were 2.7 times higher in 2020 than in 2019. While the proportion of non-English language content requested did not change, a significantly higher proportion went unfilled in 2020. The rate of unfilled requests for older items also rose significantly between 2019 and 2020. Our findings support the conclusion that the COVID-19 pandemic significantly influenced ILL article request fulfillment in health sciences libraries. Libraries should consider collection development strategies to increase the accessibility of articles held only in print, and those with specialized print collections may want to prioritize digitization of older materials. Future research on the availability, utility, and expense of the materials more likely to remain unfilled should inform publisher backfile prioritization as well as consortial and individual library collection development practices.

Sea urchins were ecologically and economically important biota, but scientific information on sea urchins is still very minimal and there is no ongoing monitoring. The purpose of this study was to determine the density, abundance, community structure, and distribution patterns of sea urchins in the intertidal zone of Karanrang Island, Pangkep Regency. The research in June-July 2022 was carried out at high and low tide using three transects measuring 1 x 1 m consisting of four plots measuring 50 x 50 cm.  Determination of stations based on information from local residents to get observation stations based on tidal conditions. The results showed that three species of sea urchins from two families were found, namely Diadema setosum, Echinothrix calamaris, and Tripneustes gratilla. The species of D. setosum was found to be very abundant (97.3-97.6%) and tended to be more abundant during high tide than during low tide. The index of diversity and uniformity of porcupine species is low (H' = 0.130-0.142 and E = 0.118-0.129). The species dominance index was in the range of 0.946-0.953 indicating high dominance of D. setosum. Spatially, D. setosum had a uniform distribution pattern, whereas E. calamaris and T. gratilla were distributed in clusters. Further spatial and temporal research is needed to comprehensively determinant the conditions of the sea urchin population on Karanrang Island, Pangkep Regency.

Peserta yang mengikuti program ini sebanyak 241 mahasiswa skema MBKM ISS dan 2.318 mahasiswa skema MBKM USK Unggul yang merupakan salah satu inovasi yang dikemas oleh USK dalam meningkatkan keikutsertaan mahasiswa MBKM. Pelaksanaan MBKM ini melibatkan 116 mitra skema ISS dan 486 mitra skema USK Unggul. Khususnya pada kegiatan MBKM Asistensi Mengajar diikuti oleh 1.252 mahasiswa, sehingga survey pada kegiatan ini dilakukan secara bertahap oleh tim universitas. Adapun tujuan pemanfaatan metode survei sebagai strategi evaluasi kegiatan ini adalah untuk dapat memastikan bahwa kegiatan asistensi mengajar di lapangan berjalan sesuai panduan MBKM USK tahun 2020. Metode survei dilakukan melalui pengamatan secara langsung kepada mitra kegiatan asistensi mengajar yaitu melalui wawancara dan penyebaran kuesioner kepada responden menggunakan google forms. Strategi evaluasi kegiatan dilakukan kepada semua yang terlibat, yaitu peserta didik, dosen pembimbing lapangan (DPL) dan sekolah sebagai mitra. Hasil pemanfaatan metode ini secara umum menjelaskan bahwa kegiatan asistensi mengajar telah berjalan tertib, aman, dan lancar tanpa adanya kendala yang berarti. Mahasiswa mejalankan tugas dan kegiatan secara terstruktur didampingi oleh pembimbing lapangan serta dosen. Namun demikian, masih ditemukan beberapa kasus minor (kecil) yang terjadi di beberapa lokasi tertentu dan dapat ditanggulangi segera pada saat pelaksanaan kegiatan. Kasus-kasus minor yang tidak dominan dan tidak terjadi di seluruh lokasi tersebut dipelajari dan diperbaiki oleh semua pemangku kepentingan termasuk pimpinan universitas sehingga kendala pada pelaksanaan kegiatan asistensi mengajar saat ini, menjadi pembelajaran perbaikan lebih baik untuk kegiatan ke depan.

Stunting is currently one of the problems in the world, including Indonesia. According to WHO (2017), Indonesia is the third country with the highest stunting problem in the Southeast Asia region. Tegal Regency, Central Java is one of the areas in Indonesia that has a stunting problem, especially in Muncanglarang Village which has a variety of potential resources. The potential in Muncanglarang Village can be used as processed food such as supplementary feeding program  (SFP) from ingredients that are easy to find in the village such as corn to make it easier for parents to provide additional food for toddlers at affordable prices. This community service activity begins with socialization, followed by demonstrations, validation, interviews, measurements, and mapping of stunting toddler locations. The result of this activity is that 20 pregnant women know about stunting and how to prevent it, mothers with toddlers know the importance of PMT and can process corn into PMT. An update on stunting data has been carried out at the puskesmas to assist the government in recording public health status. Validation was also carried out in conjunction with digital mapping to describe the location of the suspected stunted child's home using Google My Maps. The activity has achieved the goal of preventing and overcoming stunting, through providing information to pregnant women, updating and validating data and providing supplementary food.
