Published: November 2022

Dengan jumlah penduduk sekitar 291 jiwa yang tersebar di dua dusun, desa Uning Berawang Ramung adalah salah satu desa yang tingkat ketahanan pangan dan kerentanan pangannya terletak dilevel 3, kurangnya kualitas pangan dan juga penuaan pada infrastruktur ditambah dengan kurangnya investasi dalam pembangunan infrastruktur dipandang sebagai penghalang utama untuk mencapai pertumbuhan ekonomi yang diharapkan. Dalam upaya meningkatkan ketahanan pangan dan gizi, sangat penting untuk memahami tentang siapa dan berapa banyak yang rentan terhadap kerawanan pangan dan gizi, dimana mereka tinggal dan apa yang membuat mereka rentan. Sejak tahun 2003, Pemerintah Indonesia bekerja sama dengan salah satu Badan Perserikatan Bangsa-Bangsa, World Food Programme (WFP), untuk memperkuat pemahaman melalui pengembangan peta ketahanan pangan dan gizi. Peta ini berfungsi sebagai alat yang ampuh untuk meningkatkan pencapaian sasaran dan memberi informasi kepada proses pembuatan kebijakan di bidang ketahanan pangan dan gizi Pembuatan peta ketahanan dan kerentanan pangan didasarkan pada kerangka konseptual ketahanan pangan dan gizi yang dibangun berdasarkan tiga pilar ketahanan pangan yaitu ketersediaan pangan, akses pangan dan pemanfaatan pangan serta mengintegrasikan gizi dan kerentanan di dalam keseluruhan pilar tersebut. Kerentanan dalam peta ini merujuk pada kerentanan terhadap kerawanan pangan dan gizi. Tingkat kerawanan individu, rumah tangga atau kelompok masyarakat yang ditentukan oleh pemahaman terhadap faktor-faktor risiko dan kemampuan untuk mengatasi situasi tertekan.

Le principal défi de la vulgarisation et du conseil agricole au 21ème siècle est de mettre au point des approches durables de conseil qui placent des paysans au centre comme des agents de changement au sein de leur communauté. La vulgarisation de paysan à paysan (VPP) est l’une de ces approches qui a connu une croissance en Afrique cette dernière décennie. L’étude a évalué l’efficacité de l’utilisation des Animateurs Relais (AR) dans la mise en œuvre du conseil à l’exploitation familiale (CEF) par le Programme d’appui aux dynamiques productives. Les données ont été collectées auprès d’un échantillon aléatoire de 226 producteurs. Nos résultats ont montré que les adhérents ont connu une amélioration significative des capacités de gestion de trésorerie (87%), de stock de production (89%), de la main d’œuvre (70%), de planification de leurs activités (85%) et dans la définition d’un projet de développement de leur exploitation (95%). Aussi, les résultats ont-ils montré une réduction des contraintes techniques des principales cultures (68%), suivie d’une augmentation des rendements (76%). Enfin, une augmentation des revenus (91%) et une amélioration de la sécurité alimentaire (73%) ont en outre été constatées. Le profil socioéconimque des AR, l’effet de groupe, associés à la mise en œuvre du CEF expliquent les résultats obtenus.

Published: November 2022

Background. The characteristics and mortality outcomes of patients admitted to South African intensive care units (ICUs) owing to medical conditions are unknown. Available literature is derived from studies based on data from high-income countries.Objectives. To determine ICU utilisation by medical patients and evaluate the scope of admissions and clinical associations with hospital mortality in ICU patients 12 years and older admitted to an Eastern Cape tertiary ICU, particularly in the subset with HIV disease.
Methods. A retrospective descriptive one-year cohort study. Data were obtained from the LivAKI study database and demographic data, comorbidities, diagnosis, and mortality outcomes and associations were determined.Results. There were 261 (29.8%) medical ICU admissions. The mean age of the cohort was 40.2 years; 51.7% were female. When compared with the surgical emergencies, the medical subgroup had higher sequential organ failure assessment (SOFA) scores (median score 5 v. 4, respectively) and simplified acute physiology score III (SAPS 3) scores (median 52.7 v. 48.5), a higher incidence of acute respiratory distress syndrome (ARDS) (7.7% v. 2.9%) and required more frequent dialysis (20.3% v. 5.5%). Of the medical admissions, sepsis accounted for 32.4% of admission diagnoses. The HIV seroprevalence rate was 34.0%, of whom 57.4% were on antiretroviral therapy. ICU and hospital mortality rates were 11.1% and 21.5% respectively, while only acute kidney injury (AKI) and sepsis were independently associated with mortality. The HIV-positive subgroup had a higher burden of tuberculosis (TB), higher admission SOFA and SAPS 3 scores and required more organ support.
Conclusion. Among medical patients admitted to ICU, there was a high HIV seroprevalence with low uptake of antiretroviral therapy. Sepsis was the most frequently identified ICU admission diagnosis. Sepsis and AKI (not HIV) were independent predictors of mortality. Co-infection with HIV and TB was associated with increased mortality.

Published: November 2022

AbstractPancreatic cancer is a devastating malignancy with minimal treatment options. Standard‐of‐care therapy, including surgery and chemotherapy, is unsatisfactory, and therapies harnessing the immune system have been unsuccessful in clinical trials. Resistance to therapy and disease progression are mediated by the tumor microenvironment, which contains excessive amounts of extracellular matrix and stromal cells, acting as a barrier to drug delivery. There is a lack of preclinical pancreatic cancer models that reconstruct the extracellular, cellular, and biomechanical elements of tumor tissues to assess responses toward immunotherapy. To address this limitation and explore the effects of immunotherapy in combination with chemotherapy, a multicellular 3D cancer model using a star‐shaped poly(ethylene glycol)–heparin hydrogel matrix is developed. Human pancreatic cancer cells, cancer‐associated fibroblasts, and myeloid cells are grown encapsulated in hydrogels to mimic key components of tumor tissues, and cell responses toward treatment are assessed. Combining the CD11b agonist ADH‐503 with anti‐PD‐1 immunotherapy and chemotherapy leads to a significant reduction in tumor cell viability, proliferation, metabolic activity, immunomodulation, and secretion of immunosuppressive and tumor growth‐promoting cytokines.

Published: November 2022

AbstractSuffering from the competition adsorption between oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), the development of high‐efficiency oxygen electrocatalysts with bifunctional properties still remains a challenge. Herein, a novel and effective neodymium‐evoked valence electronic perturbation strategy to improve and balance reversible oxygen electrocatalysis of metallic cobalt sites is proposed. To heighten the coupling between Nd and Co, the metal‐organic‐framework‐induced method is chosen to prepare the target catalyst of atomic Nd‐doped Co on an N‐doped carbon substrate. The as‐prepared catalyst presents excellent bifunctional electrocatalytic properties with a low overpotential of 288 mV at 10 mA cm−2for the OER and a high half‐wave potential of 0.85 V for the ORR. The robust electrocatalytic stabilities for both the ORR and OER are also proven. The electrochemical in situ Raman spectra confirm the surface dynamic change of the transformation of oxygen intermediates by noting the formation of Co–OOH. Theoretical calculations verify that the adsorption of oxygen intermediates is balanced owing to the strong Co 3d‐Nd 4f orbital electronic coupling effect below the Fermi level. Moreover, the potential practicability of catalyst is further demonstrated in solid‐state rechargeable Zn‐Air batteries, which exhibit large power density and a long cycling life.

Published: November 2022

AbstractIn north‐western India, short‐term droughts due to insufficient rainfall or irrigation canal closures are common. To quantify seed cotton yield (SCY) loss under moisture deficit and evaluate the efficacy of foliar‐applied osmo‐protectants (OPs), a 2‐year field experiment was conducted with three moisture regimes (M1: well watered, M2: rainfed after single post‐sowing irrigation [POSI], and M3: rainfed after two POSIs) in main plots and eight OPs (S1: control, S2: four sprays of 2% urea at weekly intervals, S3: four sprays of 2% KNO3 at weekly intervals, S4: single spray of 500 mg kg−1 thio urea [TU], S5: single spray of 50 mg kg−1 salicylic acid [SA], S6: single spray of 100 mg kg−1 glycine betaine [GB], S7: single spray of 100 mg kg−1 SA, and S8: three sprays of 1% pink pigmented facultative methylobacteria at 10 days interval) in sub‐plots of a split plot design. Moisture stress induced a reduction of relative water content (RWC) and consequently decreased SCY by 17% and 32.9% under M3 (2821 kg ha−1) and M2 (2291 kg ha−1), respectively, compared to M1 (3418 kg ha−1). Except for TU, all tested OPs improved SCY by 6.3%–23.7% in comparison to the nontreated control. Application of SA and GB enhanced photosynthesis, improved stomatal conductance, and maintained higher RWC. Application of SA at 100 mg kg−1 resulted in an additional income of US$458 ha−1 and was the most economical treatment for countering short‐term drought.

Published: November 2022

AbstractWe report herein the synthesis of a stable plumbylone (3) by reduction of a bromodigermylplumbylene (2) with 2.2 equiv of potassium graphite (KC8). The molecular structure of3was established by a single‐crystal X‐ray diffraction study and features a two‐coordinated Pb center with an acute Ge−Pb−Ge bond angle. Computational studies showed that this complex (3) possesses a singlet electronic ground state with a Pb0center. Its high thermal stability can be most likely ascribed to the delocalization of π electrons over the Ge−Pb−Ge moiety. A preliminary reactivity study demonstrates that complex3can deliver Pb0atoms to an organic azide producing a tetrameric imido complex [(PbNDipp)4] (Dipp=2,6‐iPr‐C6H3,4) and perform a metathesis reaction with GeCl2⋅dioxane to produce a bis(germylene)‐stabilized germylone (5), highlighting the synthetic utility of3.
Access to Disentangled Ultrahigh Molecular Weight Polyethylene via a Binuclear Synergic Effect

Published: November 2022

AbstractDisentangled ultrahigh molecular weight polyethylene (dis‐UHMWPE) has excellent processability but can be achieved under extreme conditions. Herein, we report ethylene polymerization with the binuclear half‐sandwich scandium complexes C1‐Sc2 and C2‐Sc2 to afford UHMWPE. C1‐Sc2 bearing a short linker shows higher activity and gives higher molecular weight PEs than C2‐Sc2 containing a flexible spacer and the mononuclear Sc1. Strikingly, all UHMWPEs isolated from C1‐Sc2 under broad temperature range (25–120 °C) and wide ethylene pressures (2–13 bar) feature very low degree of entanglement as proved by rheological test, DSC annealing study and SEM. These dis‐UHMWPEs are facilely mediated solid‐state‐process at 130 °C and their tensile strength and modulus reach up to 149.2 MPa and 1.5 GPa, respectively. DFT simulations reveal that the formation of dis‐UHMWPE is attributed to the binuclear synergic effect and the agostic interaction between the active center and the growing chain.
A review: Multidimensional internal plasticization of molecular structure in energetic polymer

Published: November 2022

AbstractIn the field of propellant and polymer‐bonded explosives (PBX), energetic polymers may bring poor mechanical properties for bulky groups and polarity. To get rid of the defects, plasticizers with low molecular weight can enhance the flexibility and processability of propellants through monotonous mixing. However, the migration of plasticizers over time may severely disrupt the mechanical property of energetic polymers. In contrast to general plasticization, internal plasticization can regulate flexibility from the perspective of molecular structure. In this context, this review focuses on the internal plasticization of energetic polymers from different dimensions. Hopefully, this review can provide some inspiration for designing energetic polymers to optimize the mechanical properties from various dimensions and integrate them for further research.
Reconstructibility analysis and set‐observer design for Boolean control networks
Authors: Yang Junqi , Long Hao , Chen Yantao , Li Zhiqiang 
Published: November 2022

AbstractThis paper deals with the issues of reconstructibility analysis and set‐observer design for Boolean control networks (BCNs). A state estimation set is considered to find the state estimation of BCNs, and a reconstructibility judgment matrix (RJM) is obtained by compact vector of state estimation set. Then, a kind of state‐reconstructible tree is constructed, and algorithms are also provided to construct it. The state‐reconstructible tree can categorize BCNs to be globally reconstructible, locally reconstructible, and unreconstructible. The sufficient and necessary conditions for the reconstructibility of BCNs are given. Meanwhile, the relationship between input–output trajectory and estimated state is derived. Next, with the knowledge of input–output sequence, a set‐observer is designed such that the state of BCNs for any global reconstructible BCNs is uniquely determined in a finite time. Some examples are also given to illustrate the effectiveness of the proposed methods.

Published: November 2022

AbstractCellulases are used in textile, pulp and paper, brewery and wine, sugars, and ethanol industries. Four fungal isolates obtained from organic municipal solid wastes (OMSW) were selected based on their cellulolytic activity on carboxymethyl cellulose (CMC) agar medium. Based on the internal transcribed spacer (ITS) sequence of the ribosomal DNA, the four cellulolytic isolates were identified as Aspergillus fumigatus AKAL1, Aspergillus oryzae AKAL4, Aspergillus flavus AKAL8, and Aspergillus flavus AKAL9. After 9 days of fermentation at 30°C and pH 6.5 under 110 rpm agitation, these isolates produced the maximum amount of cellulase. The cellulase showed optimum activity at temperature 35–40°C and pH 6.0–7.0 and was stable for 1 h at 25–45°C and pH 5.0–7.0. The Mg2+ and Zn2+ significantly increased but Hg2+, K+, and Ca2+ severely repressed the cellulase activity. Degradation of filter papers and bio‐stoning of denim was successfully done with the crude cellulase. An endo‐β‐1,4‐glucanase was isolated and characterized from Aspergillus isolates. Genome‐wide analysis revealed that the genomes of A. oryzae, A. fumigatus, and A. flavus, the pertinent species of the fungal isolates, had 23, 25, and 22 cellulase genes, respectively. Phylogenetic analysis revealed that the cellulases in these fungal species were divided into three major groups, and the isolated endo‐β‐1,4‐glucanase clustered to Group II. Ten different motifs are present in cellulases of the three species. Results herein provide a valuable resource for understanding cellulase genes in Aspergillus species and potential application of cellulase in textile and fermentable sugars production industries.
Is there a complementary or a substitutive relationship between climate governance and analyst coverage? Its effect on climate disclosure
Authors: García‐Sánchez Isabel‐María , Ali Rizwan , Rehman Ramiz ur 
Published: November 2022

AbstractKnowledge of the initiatives that companies are promoting to curb climate change and the impacts resulting from these activities require the disclosure of relevant information that can be used by stakeholders in their decision‐making processes. The objective of this work is to complement previous studies by analysing the effect and type of relationship that exists between internal and market corporate governance mechanisms. We theoretically argue that business transparency related to climate change is explained both by climate governance and by the coverage of the company by financial analysts and that there may be both a complementary and substitutive relationship between the two mechanisms. The results obtained on a global climate governance score show the existence of a substitutive relationship, but the individualised consideration of the components of this score suggests a potential divergent relationship.

AbstractBackgroundWe explore the utility of TruSight Tumor 170 panel (TST170) for detecting somatic mutations in tumor and cfDNA from locoregional recurrent and/or metastatic head and neck squamous cell carcinoma (HNSCC).MethodsTargeted NGS of tumor DNA and plasma cfDNA was performed using TST170 panel. In addition, a set of somatic mutations previously described in HNSCC were selected for validating in tumor, plasma, and saliva by digital droplet PCR.ResultsThe TST170 panel identified 13 non‐synonymous somatic mutations, of which five were detected in tumoral tissue, other five in plasma cfDNA, and three in both tissue and plasma cfDNA. Of the eight somatic mutations identified in tissue, three were also identified in plasma cfDNA, showing an overall concordance rate of 37.5%.ConclusionsThis preliminary study shows the possibility to detect somatic mutations in tumor and plasma of HNSCC patients using a single assay that would facilitate the clinical implementation of personalized medicine in the clinic.
Ethanol Oxidation Reaction Mechanism on Gold Nanowires from Density Functional Theory
Authors: Bueno O. V. M. , San‐Miguel M. A. , da Silva E. Z. 
Published: November 2022

AbstractThin gold nanowires (NWs) are materials that could be used as support in different chemical reactions. Using density functional theory (DFT) it was shown that NWs that form linear atomic chains (LACs) are suitable for stimulating chemical reactions. To this end, the oxidation reaction of ethanol supported on the LACs of Au−NWs was investigated. Two types of LACs were used for the study, one pure and the other with an oxygen impurity. The results showed that the oxygen atom in the LAC fulfills important functions throughout the reaction pathway. Before the chemical reaction, it was observed that the LAC with impurity gains structural stability, that is, the oxygen acts as an anchor for the gold atoms in the LAC. In addition, the LAC was shown to be sensitive to disturbances in its vicinity, which modifies its nucleophilic character. During the chemical reaction, the oxidation of ethanol occurs through two different reaction paths and in two stages, both producing acetaldehyde (CH3CHO). The different reaction pathways are a consequence of the presence of oxygen in the LAC (oxygen conditions the formation of reaction intermediates). In addition, the oxygen in the LAC also modifies the kinetic behavior in both reaction stages. It was observed that, by introducing an oxygen impurity in the LAC, the activation energy barriers decrease ∼69 % and ∼97 % in the first and second reaction stages, respectively.
Pricing‐based power allocation in cloud radio access network with multiple access technology selection

Published: November 2022

AbstractIn this article, we consider an uplink economy‐efficient resource allocation framework in a multicellular cloud radio access network (C‐RAN) architecture with network virtualization, where a mobile network operator (MNO) interacts with a number of mobile virtual network operators (MVNOs) with a predetermined business model. OFDMA and Massive MIMO multiple access technologies have been assumed to be available for each MVNO at two different prices. In this setup, we propose a multi‐access technology selection approach (MATSA) with the objective of maximizing delivered rate to end users, reducing operation costs and maximizing MVNOs' profit subject to a set of constraints, which leads to a nonconvex resource allocation problem with very high computational complexity. The utility function is defined as the difference between the total throughput and the utilization cost for each technology. To tackle this problem, we apply complementary geometric programming (CGP) and successive convex approximation (SCA), that results in a two‐step iterative solution. Simulation results demonstrate superiority of the proposed approach compared to a similar scenario with predetermined multi‐access technology, especially for large numbers of users.
