The Tayler Instability in the Anelastic Approximation
Authors: Goldstein J. , Townsend R. H. D. , Zweibel E. G.
Published: August 2019

The Tayler instability (TI) is a non-axisymmetric linear instability of an axisymmetric toroidal magnetic field in magnetohydrostatic equilibrium (MHSE). In a differentially rotating radiative region of a star, the TI could drive the Tayler–Spruit dynamo, which generates magnetic fields that can significantly impact stellar structure and evolution. Heuristic prescriptions disagree on the efficacy of the dynamo, and numerical simulations have yet to definitively agree upon its existence. The criteria for the TI to develop were derived using fully compressible magnetohydrodynamics, while numerical simulations of dynamical processes in stars frequently use an anelastic approximation. This motivates us to derive new anelastic Tayler instability criteria. We find that some MHSE configurations are unstable in the fully compressible case but become stable in the anelastic case. We find and characterize the unstable modes of a simple family of cylindrical MHSE configurations using numerical calculations, and we discuss the implications for fully nonlinear anelastic simulations.

We use Atacama Large Millimeter Array observations of the host galaxy of the quasar ULAS J1342+0928 at z = 7.54, to study the dust continuum and far-infrared lines emitted from its interstellar medium (ISM). The Rayleigh–Jeans tail of the dust continuum is well sampled with eight different spectral setups, and from a modified blackbody fit we obtain an emissivity coefficient of β = 1.85 ± 0.3. Assuming a standard dust temperature of 47 K we derive a dust mass of M
dust = 0.35 × 108
M

emission. We also report multiple limits of CO rotational lines with J
up ≥ 7, as well as a tentative 3.3σ detection of the stack of four CO lines (J
up = 11, 10, 8, and 7). We find line deficits that are in agreement with local ultra-luminous infrared galaxies. Comparison of the

and

lines indicates that the

emission arises predominantly from the neutral medium, and we estimate that the photodisassociation regions in J1342+0928 have densities ≲5 × 104 cm−3. The data suggest that ∼16% of hydrogen is in ionized form and that the H ii regions have high electron densities of n

e
 > 180 cm−3. Our observations favor a low gas-to-dust ratio of <100, and a metallicity of the ISM comparable to the solar value. All the measurements presented here suggest that the host galaxy of J1342+0928 is highly enriched in metal and dust, despite being observed just 680 Myr after the big bang.

We have been conducting the Giant Metrewave Radio Telescope High Resolution Southern Sky (GHRSS) survey for the last four years and have discovered 18 pulsars to date. The GHRSS survey is an off-Galactic-plane survey at 322 MHz in a region of the sky (decl. range −40° to −54°) complementary to other ongoing low-frequency surveys. In this paper we report the discovery of three pulsars (PSRs), J1239−48, J1516−43, and J1726−52. We also present timing solutions for three pulsars previously discovered with the GHRSS survey: PSR J2144−5237, a millisecond pulsar with a period P = 5 ms in a 10 days orbit around a ≤0.18 M⊙ companion; PSR J1516−43, a mildly recycled P = 36 ms pulsar in a 228 days orbit with a companion of mass ∼0.4 M
⊙; and the P = 320 ms PSR J0514−4408, which we show is a source of pulsed γ-ray emission. We also report radio polarimetric observations of three of the GHRSS discoveries, PSRs J0418−4154, J0514−4408, and J2144−5237.

Rudolf Bultmann as historikus
Authors: Vorster Willem S.
Published: August 2019

Rudolf Bultmann as historianThe work of Bultmann has had a rather negative reception in South Africa, partly because of the fact that little attention has been paid to his historical interpretation of the New Testament. Unfortunately his name is linked only to his use of philosophical categories in Biblical interpretation. After a few remarks about his early study years and the ideas which framed his later research, the article deals with his work as historian. First he is treated as a historian of religion and then as a literary historian. An attempt is made to understand and describe his views in his contemporary context. The description is done within the framework of the academic context in which he received his training, and the scientific circle in which he performed his academic activities. In conclusion a few remarks of evaluation are made.

The effectiveness of technology based (interactive) distance learning methods in a large South African financial services organisation
Authors: Van Der Spuy M. , Wöcke A.
Published: August 2019

The trend towards technology-based learning (or ‘e-learning’) is increasing, driven largely by anecdotal evidence of advantages. This article compares the effectiveness of the technology supported learner driven distance learning methods to the ‘traditional’ classroom based teaching model and the simulation model. The results of the training methods on a sample of cashiers in a major South African bank are compared and the study finds that there were significant differences between the outcomes of three methods of training that had an impact on performance and knowledge retention with classroom based learning having the greatest impact.
An isometric normative database to facilitate restoration of function in knee-injured active young adults
Authors: Charteris J.
Published: August 2019

Prohibitive costs technologically advanced dynamometers need not dissuade rehabilitationists from making useful assessments of musculo-skeletal performance in clinical settings. The use of simple strain-gauge measures of isometric torque is demonstrated using knee flexor-extensor capacities, dominance ratios, contralateral asymmetries and sexual dimorphism ratios. Functional restoration of knee-injured active young adults, using normative charts as a data base, is a cheap and feasible option.

The precise method for measuring mediastinal widening in thoracic trauma is poorly understood and too much emphasis is placed on it as the sole criterion for performing aortography. This review article describes the established methods of measurement and their limitations, and also discusses the importance of other signs pointing to aortic rupture such as blurring of the aortic knuckle and a subjective impression of mediastinal abnormality which are more helpful in determining the need for angiography.

Modelling residential location choices with implicit availability of alternatives
Authors: Haque Md Bashirul , Choudhury Charisma Farheen , Hess Stephane
Published: August 2019

Choice set generation is a challenging aspect of disaggregate level residential location choice modelling due to the large number of candidate alternatives in the universal choice set (hundreds to hundreds of thousands). The classical Manski method (Manski, 1977) is infeasible here because of the explosion of the number of possible choice sets with the increase in the number of alternatives. Several alternative approaches have been proposed in recent years to deal with this issue, but these have limitations alongside strengths. For example, the Constrained Multinomial Logit (CMNL) model (Martínez et al., 2009) offers gains in efficiency and improvements in model fit but has weaknesses in terms of replicating the Manski model parameters. The rth-order Constrained Multinomial Logit (rCMNL) model (Paleti, 2015) performs better than the CMNL model in producing results consistent with the Manski model, but the benefits disappear when the number of alternatives in the universal choice set increases. In this study, we propose an improved CMNL model (referred to as Improved Constrained Multinomial Logit Model, ICMNL) with a higher order formulation of the CMNL penalty term that does not depend on the number of alternatives in the choice set. Therefore, it is expected to result in better model fit compared to the CMNL and the rCMNL model in cases with large universal choice sets. The performance of the ICMNL model against the CMNL and the rCMNL model is evaluated in an empirical study of residential location choices of households living in the Greater London Area. Zone level models are estimated for residential ownership and renting decisions where the number of alternatives in the universal choice set is 498 in each case. The performance of the models is examined both on the estimation sample and the holdout sample used for validation. The results of both ownership and renting models indicate that the ICMNL model performs considerably better compared to the CMNL and the rCMNL model for both the estimation and validation samples. The ICMNL model can thus help transport and urban planners in developing better prediction tools.
Measuring full cost accessibility by auto
Authors: Cui Mengying , Levinson David
Published: August 2019

Traditionally accessibility has been analyzed from the perspective of the mean or expected travel time, which fails to capture the full cost, especially the external cost, of travel. The full cost accessibility (FCA) framework, proposed by Cui and Levinson (2018), provides a theoretical basis to fill the gap. It combines temporal, monetary, and non-monetary internal and external travel costs into accessibility evaluations, considering the time cost, crash cost, emission cost, and monetary cost. This paper extends the FCA framework and measures the full cost accessibility by auto for the Minneapolis - St. Paul Metropolitan area, demonstrating the practicality of the FCA framework on real networks.
Aportes de la Biodanza a la estética contemporánea: estética vivencial, creatividad existencial y mirada
Authors: Valle Contreras Marta Eugenia , Zetino Mario
Published: August 2019

Este ensayo explora la dimensión estética que fundamenta la propuesta educativa y re-educativa de la Biodanza y su extensión, la educación biocéntrica, creadas por Rolando Toro Araneda (Chile, 1924 - 2010). Se dis­cute las coincidencias y aportes de la pro­puesta de Toro frente a las visiones estéticas contemporáneas. Aunque la Biodanza y la educación biocéntrica comparten algunos aspectos con las estéticas contemporáneas, el enfoque radical de la Biodanza en los pro­cesos existenciales vinculados a la vivencia como medio experiencial integral, lleva a una concepción biológica de la creatividad, y a una visión estética diferente de la con­cepción contemporánea, lo que resignifica y enriquece la dimensión estética para la vida.

Lógica da (In)apropriação? Os problemas do construtivismo na análise do alargamento da União Européia
Authors: Mielniczuk Fabiano Pellin
Published: August 2019

Muitos construtivistas na área de Integração Européia oferecem explicações sobre o processo de alargamento da UE a partir da lógica da apropriação, opondo-a a explicações baseadas na lógica da conseqüência. A primeira seria fundada em uma ontologia construtivista, indicando a prevalência das normas na determinação do comportamento dos atores. Já a segunda é associada a uma ontologia racionalista, com atores que interagem a partir de identidades pré-definidas, não constituídas pelas normas dos contextos de interação. Na medida em que os candidatos do leste da Europa foram incorporados ao processo de adesão, esperava-se a adequação de suas condutas às normas que conferiam identidade à União Européia. O problema é que a lógica da apropriação pressupõe a existência de normas institucionalizadas, de modo que as ações dos não-membros pudessem ser comparadas a elas e consideradas “apropriadas” ou não. Isso implica, também, que os membros da UE deveriam reproduzir em suas ações o que prescrevem para que novos candidatos fossem aceitos. Todavia, uma breve análise do trato conferido às minorias indica que essas duas condições não foram satisfeitas durante o processo de alargamento. O artigo elabora os motivos teóricos e políticos para essa inconsistência, e propõe que o modelo construtivista é inapropriado.

Total reducing capacity in Arabidopsis thaliana cat2cat3 knockout mutants under heat stress
Authors: Panchuk I. I. , Buzduga I. M. , Volkov R. A.
Published: August 2019

Aim. It was investigated whether the simultaneous loss of the two catalase isoforms CAT2 and CAT3 can be compensated by the increase in content of low-molecular weight antioxidants. To clarify this question, the total reducing capacity in Arabidopsis wild type and cat2cat3 knockout mutants was evaluated under optimal growth conditions and after heat stress. Methods. Leaves of Arabidopsis thaliana wild type and cat2cat3 knockout mutants were exposed to high temperatures. The content of water-soluble low molecular weight antioxidants was evaluated by determining the total reducing capacity using iodometry. Results. In intact cat2cat3 mutants there is an 1.7 times increase in the content of low-molecular weight antioxidants compared to wild type plants. A high content of these compounds in knockout plants was also observed upon heat stress. Patterns of changes in total reducing capacity differ between wild type and knockout lines. Conclusion. The loss of activity of the catalase isoforms CAT2 and CAT3 in knock-out mutants of Arabidopsis results in activation of non-enzymatic antioxidant defenses. The increase of the content of low-molecular weight antioxidants is one of the mechanisms that provide protection of mutant plants from chronic oxidative stress, both under optimal cultivation conditions and under the influence of elevated temperatures.Keywords: multigenic family, heat shock, total reducing capacity, knockout mutants, Arabidopsis thaliana.
Role of salicylate and jasmonate signaling in lipopolysaccharide-induced resistance of Arabidopsis thaliana to the phytopathogenic strain of Pseudomonas aeruginosa IMB 9096

Published: August 2019

Aim. The aim of the investigation was to study the effect of lipopolysaccharides (LPS) derived from saprophytic strains of Pseudomonas aeruginosa on the resistance to phytopathogenic strain of P. aeruginosa IMB 9096. The wild-type (Col-0) Arabidopsis thaliana plants, npr1 mutant, which lacks expression of PR-genes, NahG genotype plants, expressing the bacterial gene of NahG salicylate hydrolase, jin1 mutant, insensitive to jasmonic acid, have been used as a model systems in resistance testing. Methods. Common phytopathological methods were used. Results. Lipopolysaccharide from the saprophyte P. aeruginosa IMV 8614 strain increased the resistance of seedlings of all genotypes to infection with phytopathogenic strain P. aeruginosa IMB 9096. The most effective protection had been observed in the mutant jin1. The protective effect was also observed in jin1 after the treatment with LPS derived from the saprophyte strain P. aeruginosa IMV 8615. LPS 8615 increased the sensitivity to infection in the NahG and npr1 transgenic plants, especially in NahG. LPS from the saprophyte P. aeruginosa IMV 8616 increased resistance to P. aeruginosa IMB 9096 infection in all four A. thaliana genotypes. Conclusions. The effect of LPS derived from different strains of saprophytic bacteria can both increase and decrease the sensitivity of plants to infection with bacterial phytopathogens. The effect of LPS depends upon the bacteria strain and the functional state of the salicylate and jasmonate signaling systems in the infected plants.Keywords: Arabidopsis thaliana, Pseudomonas aeruginosa, lipopolysaccharide, induced resistanse
Evolution of Darwinism. The classical stage: 1859 — 1926 years
Authors: Vagyn Y. V.
Published: August 2019

The development of the theory of Darwin from 1859 to 1926 is considered. The «cohesive ephemeral» theory of heredity, dominant at this stage, was destroying the nucleus of the Darwinian concept — the notion of natural selection as the leading factor in evolution. The results of studies of geneticists of the first decades of the 20th century also pointed to the futility of the theory of natural selection as a factor directing the process of biological evolution. Keywords: «Origin of Species»; «indefinite» hereditary variability; «certain» hereditary variability; natural selection; «conjointly ephemeral» theory of heredity; «constant-corpuscular» theory of heredity.

Compensation Decisions on Disruption Recovery Service in Urban Rail Transit
Authors: Yang Zhijie , Chen Xiaolong
Published: August 2019

Ride-hailing, in addition to a common mode of daily transportation, is an attractive option for evacuating stranded passengers and supplementing bus bridging in the early stages of an urban rail transit (URT) disruption. This paper proposes a service supply chain comprised of ride-hailing vehicles, ride-hailing platforms, and stranded passengers wherein the URT and ride-hailing chain together provide emergency evacuation services. The emergency evacuation service supply chain can be coordinated under an effort-based revenue sharing contract. A URT-dominated Stackelberg game model between the URT and ride-hailing platform is then formulated to optimize compensation decisions on the part of the URT; numerical analysis reveals critical factors affecting the said decisions. The main contributions of this paper are two-fold: first, it provides new information regarding collaboration between URT operators and ride-hailing platforms for stranded passenger evacuation, including a ride-hailing platform pricing strategy; and second, the URT compensation decision process is solved via Stackelberg game model while revealing an incentive coefficient parameter for the URT decision and solver.

Published: August 2019

The history of ancient Harappan and Egyptian civilizations was and still an area of interest attracting researchers and scholars all over the world, to investigate the constituents and the hidden secrets of such great civilizations. Undoubtedly, archaeology is standing as the main science concerned with studying the cultural products of ancient societies, especially the material culture represented by all physical remains whether organic or inorganic ones. However, there are certain drawbacks associated with the extensive use of archaeological methods only. Consequently, this project seeks to use additional tools, methods, and approaches that would open new dimensions of investigation and analysis. This could be attained by adopting the anthropological perspective as the main entrance for revisiting the ancient Harappan and Egyptian civilizations differently. This does not mean that anthropology is an alternative to archaeology, but both are complementary to each other. Owing to various approaches used under the umbrella of anthropology like; ethno-archaeology, bio-archaeology, bio-culture, ethnography approaches etc. Anthropological perspectives have the ability to study cultural, social and biological dimensions of different societies like Harappan and Egyptian, whether recent or ancient. Consequently, the present study objective is to utilize the anthropological methods to help filling these gaps, which are persisted in the knowledge of ancient Harappan and Egyptian civilizations. Especially those issues related to; kingship, administration, kinship, political and socio-cultural life, environment, religion, dress, gender, human body in funerary and medical treatments, funerary populations, grave gods, fertility, birth, child-care, health, hygiene, studies on human skeletons, and everyday life. That is to mean that all human- mediated processes and events would be included within the scope of this project regarding anthropology.
Tropical Forest: A Potential Resource for Climate Change Mitigation in Ghana
Authors: Amankwah Emmanuel
Published: August 2019

Climate variability and change has become a global phenomenon with many countries including Ghana working hard to mitigate the effect or develop strategies for adaptation.  However, tropical forest has been identified to have the capacity to mitigate the impact of climate change and improve the general environment. The forest plays a critical role in the climate system, hydrology and the carbon cycle, and provide livelihood for over 2.5 billion rural dwellers in developing countries. This article therefore highlights the importance of tropical forest as a potential resource for climate change mitigation and the need for policy makers, stakeholders and the general public to seriously adopt positive approach to the management of forest resources. The article was carried out through extensive review of literature, official reports and policy documents.  The paper outlines the threat of climate change, the state of Ghana’s forest and climate, and the role of the forest to mitigate climate change. It also highlights the socio-economic benefits of the forest in mitigating the changing climate. The documents reviewed showed that the state of Ghana’s forest has dwindled over the years through anthropogenic activities and the climate is also changing. It was also established that trees can remove substantial amount of CO2 from the atmosphere for storage. The paper concludes with recommendations for the preservation and regeneration of the tropical forest for the purpose of mitigating the effect of climate change in Ghana.

Published: August 2019

Aims: This study aimed to evaluate the influence of nitrogen fertilization and inoculation of seeds with Rhizobium tropici on the agronomic performance of common bean (Phaseolus vulgaris L.).

Study Design: The experimental design consisted of a randomized block in a 4x2 factorial layout, with 4 replicates, the first factor referring to inoculant doses (0, 50, 100 and 200 mL for each 25 kg of seed), while the second refers to nitrogen fertilization (0 and 40 kg ha of N).

Place and Duration of Study: The study was conducted to the field in a no-till system area, in the southwestern region of Paraná, Brazil. The soil is classified as a Purple Latosol, with a clayey texture.

Methodology: The adopted spacing was 0.45 m between rows, and the seeding density used was 12 seeds per furrow meter. The inoculants NITRO 1000 Rhizobium tropici SEMIA 4077 and SEMIA 4088 were applied, varied according to the treatments. The cultivar used was IPR – Tangará.

Results: As for grain yield, it was observed that nitrogen fertilization did not contribute to the increase in grain yield, and higher productivity was obtained in the absence of N. This was probably due to the high content of organic matter present in the soil.

Conclusion: Nitrogen fertilization at sowing and seed inoculation with Rhizobium tropici did not influence the plant population and the 1000-grain mass. In the absence of nitrogen fertilization at sowing, pods with a longer length and higher grain yield were obtained. Inoculation of the seeds with Rhizobium tropici exerts a positive influence on plant height, number of nodes of the main stem, number of pods per plant, and number of beans per pod, the dose recommended by the manufacturer (100 mL) being efficient, with the possibility of applying a dose of 50 mL, to satisfactory results.

This paper presents the evaluation of propagation losses due to rain attenuated signal on   terrestrial radio link. Rain rate data were measured using Davis weather station for the months of July, August and October 2017 at (9.9565° N, 8.8583° E; 1258 meters) Jos Plateau state of Nigeria. The data were analyzed using Microsoft Excel application package. Results were calculated based ITU-Recommendation. The result for the month of July shows that rain   attenuated signals become more severe from rain rate of 90 mm/hr at 0.014% to 160 mm/hr at 0.002% with attenuation of 31.215dB and 105.951dB respectively. Also, the month of August shows that rain attenuated signals become more severe from rain rate of 70mm/hr at 0.017% to 200mm/hr at 0.002% with attenuation of 69.509dB and 108.324dB respectively. Furthermore, the month of October shows that rain attenuated signals become more severe from rain rate of 70mm/hr at 0.014% to 160 mm/hr at 0.004 with attenuation of 50.301dB and 135.336dB respectively. Therefore, results from this study revealed that rain attenuated signals on terrestrial radio links in Jos-Nigeria is more severe at higher rainfall rate (above 60 mm/hr) and lower exceeded frequency percentage of time (0.01% to 0.001%).

This study describes antibiotic use by small-scale freshwater aquaculture farmers in the upper Mekong Delta in southwestern Vietnam and the knowledge and practices surrounding the cause and prevention of aquaculture disease in that region. Forty five farmers were included in the study, of which 19 (42%) cultivated tilapia Oreochromis spp., 13 (29%) Striped Catfish Pangasianodon hypophthalmus and 13 (29%) giant river prawns Macrobrachium rosenbergii. Antibiotics were used by farmers of tilapia and Striped Catfish (84% and 69% of farmers, respectively), but not by any of the prawn farmers. Most farmers (72%) used antibiotics for around 3 d when treating diseases, depending on the farmers' economic means and whether the fish recovered, as judged by the farmer. If farmers perceived that the antibiotic treatment had failed, the most common response was to change to another type of antibiotic. Some farmers also used antibiotics in the absence of clinical symptoms as a preventive measure. In the absence of rapid, cost-effective diagnostics, the likelihood for the incorrect use of antibiotics is high, which has implications for antibiotic resistance. Moreover, the sequential use of different antibiotics following therapeutic failure is a risk factor for the emergence of resistance. All farmers that were surveyed were aware of the risks associated with antibiotic use. This may lead to successful intervention toward reduced antibiotic use in freshwater fish farming in Vietnam.

Polymorphs of organic semiconductors are of great interest as they shed light to structure‐property relationships. The full X‐ray thin film structure analysis of two polymorphs (B, G) of an important n‐type semiconducting dicyano‐distyrylbenzene based small molecule (CN‐TFPA) is reported. Drastically different structures of the monotropic phases are revealed, that is an uncommon 2D crossed π‐stacked arrangement for the B‐phase versus a 1D slipped π‐stack for G. Both phases exhibit a layered structure in the (100) plane with high structural integrity, driven by the hydrophobic contacts of the terminal CF3 groups; as (100) coincides with the film surface, this allows for exfoliation by scotch tape. An in‐depth time‐dependent density functional theory (TD‐DFT) based quantum mechanics/molecular mechanics (QM/MM) study reveals all subsequent significantly differing optical and electronic responses which result from the different arrangements: the B film shows little excitonic interaction with strong blue fluorescence, amplified spontaneous emission (ASE), and good 2D n‐type transport. The G film forms H‐aggregates with strong green fluorescence, no ASE, and 1D n‐type charge transport. The established structure‐property relationships are seen as a crucial step for computer‐aided device analysis.

Published: August 2019

A nickel(II)/diamine‐catalyzed diastereo‐ and enantioselective Michael/hemiacetalization cascade reaction of α‐ketoesters with 2‐(2‐nitrovinyl)phenols has been established, thus providing a range of structurally diverse polysubstituted chromanes in good yields and excellent stereoselectivities (up to 89% yield, >20:1 dr, >99% ee). Moreover, the gram‐scale experiment was performed with only 0.5 mol% of catalyst, and tricyclic furanobenzodihydropyran compound was gained by the derivatization of product, which showed the great synthetic potential of this strategy.

Published: August 2019

The 22q11.2 deletion syndrome (22q11.2DS) is a multisystem condition and the most prevalent microdeletion syndrome in humans. Approximately 25% of individuals with 22q11.2DS receive antipsychotic treatment. To assess whether patients with 22q11.2DS are vulnerable to adverse effects of antipsychotic medication, we carried out a literature review. A systematic search strategy was performed using PubMed (Medline), Embase, PsychInfo, and Cochrane Database of Systematic Reviews. Publications describing adverse effects of antipsychotic medication in patients with 22q11.2DS were included in the review and assessed for their methodological quality. A total of 11 publications reporting on eight trials, cross‐sectional or cohort studies, and 30 case reports were included. The most commonly reported adverse effects can be classified into the following categories: movement disorders, weight gain, seizures, cardiac side effects, and cytopenias. Many of these symptoms are manifestations of 22q11.2DS, also in the absence of antipsychotic medication. Based on the reviewed literature, a causal relation between antipsychotic medication and the reported adverse effects could not be established in the majority of cases. Randomized clinical trials are needed to make firm conclusions regarding risk of adverse effects of antipsychotics in patients with 22q11.2DS.

Published: August 2019

Coacervate microdroplets produced by liquid–liquid phase separation have been used as synthetic protocells that mimic the dynamical organization of membrane‐free organelles in living systems. Achieving spatiotemporal control over droplet condensation and disassembly remains challenging. Herein, we describe the formation and photoswitchable behavior of light‐responsive coacervate droplets prepared from mixtures of double‐stranded DNA and an azobenzene cation. The droplets disassemble and reassemble under UV and blue light, respectively, due to azobenzene trans/cis photoisomerisation. Sequestration and release of captured oligonucleotides follow the dynamics of phase separation such that light‐activated transfer, mixing, hybridization, and trafficking of the oligonucleotides can be controlled in binary populations of the droplets. Our results open perspectives for the spatiotemporal control of DNA coacervates and provide a step towards the dynamic regulation of synthetic protocells.
