description: We analyze the possible existence of topological phases in two-legged spin ladders considering a staggered interaction in both chains. When the staggered interaction in one chain is shifted by one site with respect to the other chain, the model can be mapped, in the continuum limit, into a non linear sigma model NL$σ$M plus a topological term which is nonvanishing when the number of legs is two. This implies the existence of a critical point which distinguishes two phases. We perform a numerical analysis of energy levels, parity and string non-local order parameters, correlation functions between $x,y,z$ components of spins at the edges of an open ladder, the degeneracy of the entanglement spectrum and the entanglement entropy in order to characterize these two different phases. Finally, we identify one phase with a Mott insulator and the other one with a Haldane insulator.

description: In this paper, Data Envelopment Analysis (DEA) technique was applied for apple (Red and Golden delicious varieties) producers in West Azarbaijan province, Iran (2008-2009). Results showed that the highest share of energy consumption belongs to packaging (57%) and irrigation (16%). Highest share of expenses were found to be 34% and 30% for labor and packaging, respectively. The total energy input for apple production, energy productivity, net energy and output-input energy value were estimated as 101,505 MJ.ha-1, 0.23 kg.MJ-1, -56.320 MJ.ha-1 and 0.44, respectively. Also, The study has helped to segregate efficient farmers from inefficient ones, identify wasteful uses of energy by inefficient producers and suggest reasonable savings in energy uses from effective sources while it describes the process of benchmarking energy inputs and apple yield. Technical, pure technical and scale efficiencies were calculated (by using CCR and BCC models) for all orchards. Inquiries on 80 orchards were conducted in a face-to-face interviewing. The VRS analysis showed that only 41 out of 80 DMUs were efficient. The TE of the inefficient DMUs was calculated as 87.8%. This implies that 12.2% of overall resources could be saved by raising the performance of these DMUs to the highest level. Results showed that the maximum share to the total energy saving is from diesel (39.7%) followed by packaging and about (28.1%). The results of analysis showed that DEA is an effective tool to analyze and benchmark productive efficiency of farms.
A Model of Whole-Body Regeneration in a Larval Echinoderm

Subjects: Developmental Biology

description: Regeneration remains one of science and medicine’s greatest mysteries. It represents an incredible feat that only manifests itself in particular metazoan taxa. Furthermore, some animals are limited to digit and limb regeneration, while others undergo extensive regeneration termed whole-body regeneration. Those animals that can regenerate must be able to detect which tissues are missing, coordinate theproduction of lost tissues, and integrate new material with their pre-existing anatomy. On a molecular level, many studies have identified commonalities in the mechanismsthat drive this process in highly regenerative organisms and the gene regulatory machinery that underlie them. However, in order to piece together a complete picture ofregeneration, we must explore these commonalities in species across the phylogenetic tree. Is regeneration an ancestral trait that was lost in certain lineages? Or has it been independently adapted across evolutionary time? This study aims to extend the knowledge of regeneration to an invertebrate deuterostome model of whole-bodyregeneration, the larva of the bat star Patiria miniata .This study has produced three key findings. First, sea star larval regeneration involves rapid epithelial wound healing that utilizes localized cell migration and actin assembly. Wound signaling in this system also strongly activates components of the MAPK signaling pathway, including the phosphorylation of ERK, and a battery of gene expression. Second, sea star larvae use blastemal proliferation in order to reform tissues lost from amputation. The cells of the eventual blastema are specifically activated for regeneration and are distinct from proliferating cells of the uncut larva.Third, early MAPK signaling functions in regeneration to ensure correct expression of genes during the wound response. This pathway is also implicated in regulating axisre-specification and blastemal proliferation during regeneration. Together, these results have allowed us to synthesize a model of larval echinoderm whole-body regeneration.

description: In part (I) of this two paper series on stripe fractionalization, we argued that in principle the `domain wall-ness' of the stripe phase could persist in the spin and charge disordered superconductors, and we demonstrated how this physics is in one-to-one correspondence with Ising gauge theory. Here we focus on yet another type of order suggested by the gauge theory: the quantum spin nematic. Although it is not easy to measure this order directly, we argue that the superconducting vortices act as perturbations destroying the gauge symmetry locally. This turns out to give rise to a simple example of a gauge-theoretical phenomenon known as topological interaction. As a consequence, at any finite vortex density a globally ordered antiferromagnet emerges. This offers a potential explanation for recent observations in the underdoped 214 system.

description: Bayesian optimization has recently emerged as a popular method for the sample-efficient optimization of expensive black-box functions. However, the application to high-dimensional problems with several thousand observations remains challenging, and on difficult problems Bayesian optimization is often not competitive with other paradigms. In this paper we take the view that this is due to the implicit homogeneity of the global probabilistic models and an overemphasized exploration that results from global acquisition. This motivates the design of a local probabilistic approach for global optimization of large-scale high-dimensional problems. We propose the $\texttt{TuRBO}$ algorithm that fits a collection of local models and performs a principled global allocation of samples across these models via an implicit bandit approach. A comprehensive evaluation demonstrates that $\texttt{TuRBO}$ outperforms state-of-the-art methods from machine learning and operations research on problems spanning reinforcement learning, robotics, and the natural sciences.

description: We study how stronger noise can enhance the entanglement in inhomogeneously monitored quantum systems. We consider a free fermions model composed of two coupled chains - a system chain and an ancilla chain, each subject to its own different noise - and explore the dynamics of entanglement within the system chain under different noise intensities. Our results demonstrate that, contrary to the detrimental effects typically associated with noise, certain regimes of noise on the ancilla can significantly enhance entanglement within the system. Numerical simulations demonstrate the robustness of such entanglement enhancement across various system sizes and noise parameters. This enhancement is found to be highly dependent on the hopping strength in the ancilla, suggesting that the interplay between unitary dynamics and noise can be tuned to optimize the entanglement of a quantum system.

UV/IR Mixing via Closed Strings and Tachyonic Instabilities

description: We discuss UV/IR mixing effects in non-supersymmetric non-commutative U(N) gauge theories. We show that the singular (non-planar) terms in the 2- and 3-point functions, namely the poles and the logarithms, can be obtained from a manifestly gauge invariant effective action. The action, which involves open Wilson line operators, can be derived from closed strings exchange between two stacks of D-branes. Our concrete example is type 0B string theory and the field theory that lives on a collection of N electric D3-branes. We show that one of the closed string modes that couple to the field theory operator which is responsible for the infrared poles, is the type 0 tachyon.

description: Garnet has been widely used to decipher the pressure-temperature-time history of rocks, but its physical properties such as elasticity and diffusion are strongly affected by trace amounts of hydrogen. Experimental measurements of H diffusion in garnet are limited to room pressure. We use atomistic simulations to study H diffusion in perfect and defective garnet lattices, focusing on protonation defects at the Si and Mg sites, which are shown to be energetically favored. The ab-initio simulation of H diffusion is computationally challenging due to a transient trapping of H, which is overcome with machine learning techniques by training a deep neural network that encodes the interatomic potential. Our results show high mobility of hydrogen in defect free garnet lattices, whereas H diffusivity is significantly diminished in defective lattices. Tracer simulation focusing on H alone highlights the vital role of atomic vibrations of heavier atoms like Mg in the untrapping of H atoms. Two regimes of H diffusion are identified: a diffuser-dominated regime at high hydrogen content with low activation energies, due to saturation of vacancies by hydrogen, and a vacancy-dominated regime at low hydrogen content with high activation energies, due to trapping of H atoms at vacancy sites. These regimes account for experimental observations, such as a H-concentration dependent diffusivity and the discrepancy in activation energy between deprotonation and D-H exchange experiments. This study underpins the crucial role of vacancies in H diffusion and demonstrates the utility of machine-learned interatomic potentials in studying kinetic processes in the Earth's interior.

description: We analyse gender differences in children’s aspirations and academic beliefs that affect their academic potential. We use administrative data on the test scores of a primary school in rural China and a novel survey instrument in the evaluation of a randomised controlled trial of a role-model intervention. Our intervention increases Chinese test scores by 0.116 standard deviations, which is driven by boys’ 0.33–0.35 standard-deviation performance boost that persists into 1 year after the treatment. Girls only experience a short-term increase in performance within a week after the treatment. The impact of the treatment is especially pronounced for children starting with low aspiration, self-efficacy, or cognitive ability. While there is no average impact on Mathematics test scores, we find that boys holding traditional gender attitudes and having a high self-efficacy, and girls of high self-efficacy and aspirations, perform better in response to the treatment. Aspirations, confidence, and gender attitudes account for parts of our findings.

description: This study analyzed the role played by Fadama II on road development in Adamawa State, Nigeria. The data were obtained from 300 respondents who were randomly selected from Fadama II beneficiaries, non-beneficiaries within Fadama II communities and non-beneficiaries outside Fadama II communities. Based on propensity score matching (PSM) and double difference estimator (DD), the data were analyzed using frequencies, percentages and balancing test (t-test). The results showed that 30% of the roads were funded by Fadama II Project. Most of the roads were constructed and rehabilitated after the establishment of the project. Fadama II roads were found to be important for the beneficiaries’ activities. The analysis established that beneficiaries’ travel distance, travel time, waiting time and transport fares were reduced relative to non-beneficiaries. Road development has boosted marketing services for both farm and non-farm economic activities. Spill-over effect also manifests in the adjoining communities.

description: We analyze the transmission and reflection of the electromagnetic wave calculated from transfer matrix simulations of periodic arrangements of thin metallic wires. The effective permittivity and the absorption is determined. Their dependence on the wire thickness and the conductance of the metallic wires is studied. The cutoff frequency or effective plasma frequency is obtained and is compared with analytical predictions. It is shown that the periodic arrangement of wires exhibits a frequency region in which the real part of the permittivity is negative while its imaginary part is very small. This behavior is seen for wires with thickness as small as 17 $μ$m with a lattice constant of 3.33 mm.

description: The effect treatments with the recommended application rates of avermectin, buprofezin, white oil, lambda-cyhalothrin and cyromazine on Trialeurodes vaporariorum Westwood (Aleyrodidae: Homoptera) was evaluated. Pesticides were applied against larvae infesting brinjal (Solanum melongena L.) and tomato (Lycopersicon esculentum Mill) plants in a natural environment of the Cameron Highlands, Pahang, Malaysia. We also examined whether these pesticides affect the whitefly predator, Macrolophus caliginosus Wagner (Heteroptera: Miridae). Tested pesticides significantly reduced the larval populations of the whitefly and affect throughout the survey period. Similar effects were observed on the predator except for the white oil. Avermectin was the most effective insecticide against the population of T. vaporariorum. However, it was highly toxic to the predator, M. caliginosus. Considering relatively low mammalian toxicity of buprofezin and white oil, these two insecticides were more suitable for controlling whiteflies, particularly during fruiting period. Proper selection of effective pesticides against the pest, but less harmful to natural enemies and also good timing of their applications are essential in formulating an Integrated Pest Management (IPM) programme for whiteflies.

description: Wigner's quasi-probability distribution function in phase-space is a special (Weyl) representation of the density matrix. It has been useful in describing quantum transport in quantum optics; nuclear physics; decoherence (eg, quantum computing); quantum chaos; "Welcher Weg" discussions; semiclassical limits. It is also of importance in signal processing. Nevertheless, a remarkable aspect of its internal logic, pioneered by Moyal, has only emerged in the last quarter-century: It furnishes a third, alternative, formulation of Quantum Mechanics, independent of the conventional Hilbert Space, or Path Integral formulations. In this logically complete and self-standing formulation, one need not choose sides--coordinate or momentum space. It works in full phase-space, accommodating the uncertainty principle. This is an introductory overview of the formulation with simple illustrations.

description: The study on biodiversity of aquatic insects was carried out covering the area of Kuala Keniam to Kuala Perkai River, National Park, Pahang, Malaysia. The macro invertebrate community was found in the different types of micro-habitat and various flowing speed levels in good quality of water of Keniam Rivers consisted mainly of aquatic insects. There are large numbers and wide species of aquatic insects in aquatic habitats make them of great ecological importance. There are three divided strata with total of nine sampling location were carried out within several varieties of microhabitats such as sandy, cobble, gravel, leaf and the pool area. The aquatic insects were collected and sampled by using a D-framed aquatic kick net. There was a wide variety of aquatic insects belonging to at least 8 orders in the study area. The orders of insect were Odonata, Coleoptera, Diptera, Trichoptera, Thysanura, Orthopthera, Hemiptera and Ephemeroptera. Throughout the study period, there is range from total of 140 to 604 individuals of aquatic insect trapped monthly and collected in Keniam River from September 2009 to December 2010. Some group of aquatic insects were found significant (χ2<0.05) different abundance between strata and sampling dates as well as habitat on the diversity of aquatic insects in Keniam River. The abundance and distribution of aquatic insects‟ species were varied and not constant from one month to another during the study period due to biotic and abiotic factors. Species diversity of aquatic insects varied in different strata of the Keniam River. This indicates the richness and diverse groups of aquatic insects in the study area. It adds to the fact that the undisturbed habitat quality is most suitable for insects to breed and multiply under the natural ecosystem with abundant food supply. Moving upstream from Kuala Perkai to lower stream to Kuala Keniam, one can observe various types of habitats for aquatic insects to live.

description: With the increasing interest in Quantum Machine Learning, Quantum Neural Networks (QNNs) have emerged and gained significant attention. These models have, however, been shown to be notoriously difficult to train, which we hypothesize is partially due to the architectures, called ansatzes, that are hardly studied at this point. Therefore, in this paper, we take a step back and analyze ansatzes. We initially consider their expressivity, i.e., the space of operations they are able to express, and show that the closeness to being a 2-design, the primarily used measure, fails at capturing this property. Hence, we look for alternative ways to characterize ansatzes by considering the local neighborhood of the model space, in particular, analyzing model distinguishability upon small perturbation of parameters. We derive an upper bound on their distinguishability, showcasing that QNNs with few parameters are hardly discriminable upon update. Our numerical experiments support our bounds and further indicate that there is a significant degree of variability, which stresses the need for warm-starting or clever initialization. Altogether, our work provides an ansatz-centric perspective on training dynamics and difficulties in QNNs, ultimately suggesting that iterative training of small quantum models may not be effective, which contrasts their initial motivation.

description: To better understand lipid membranes in living organisms, the study of intermolecular forces using the osmotic pressure technique applied to model lipid membranes has constituted the ground knowledge in the field of biophysics since four decades. However, the study of intermolecular forces in lipid systems other than phospholipids, like glycolipids, has gained a certain interest only recently. Even in this case, the work generally focuses on the study of membrane glycolipids, but little is known on new forms of non-membrane functional compounds, like microbial bolaform glycolipids. This works explores, through the osmotic stress method involving an adiabatic humidity chamber coupled to neutron diffraction, the short-range (< 2 nm) intermolecular forces of membranes entirely composed of interdigitated glucolipids. Experiments are performed at pH 6, when the glucolipid is partially negatively charged and for which we explore the effect of low (16 mM) and high (100 mM) ionic strength. We find that this system is characterized by primary and secondary hydration regimes, respectively insensitive and sensitive to ionic strength and with typical decay lengths of 0.37 +- 0.12 nm and 1.97 +- 0.78 nm.

description: We present high resolution Halpha rotation curves of 4 late-type dwarf galaxies and 2 low surface brightness galaxies (LSB) for which accurate HI rotation curves are available from the literature. Observations are carried out at Telescopio Nazionale Galileo (TNG). For LSB F583-1 an innovative dispersing element was used, the Volume Phase Holographic (VPH) with a dispersion of about 0.35 A/pxl. We find good agreement between the Halpha data and the HI observations and conclude that the HI data for these galaxies suffer very little from beam smearing. We show that the optical rotation curves of these dark matter dominated galaxies are best fitted by the Burkert profile. In the centers of galaxies, where the N-body simulations predict cuspy cores and fast rising rotation curves, our data seem to be in better agreement with the presence of soft cores.

description: In the bioethanol production process, as much as 90% of waste was produced. The availability of waste production is very important since waste can be processed to become livestock feed. The solid bioethanol waste contains cyanide (HCN) 5.8177 mg/kg, water 95,21%, ash 0,39%, protein 8,16%, crude fiber 5,45%, crude fat 2.06%, and carbohydrates 83,94%. Processing bioethanol solid waste into livestock feed can be done by utilizing the existing fungi on bioethanol solid waste. Crude fiber (cellulose) and carbohydrates are a source of cellulolytic fungi. Cellulolytic fungi can degrade the role of organic materials contained in bioethanol solid waste, so that it can be made as a source of highly nutritious livestock feed. This study aims to determine the types of cellulolytic fungal isolates contained in bioethanol solid waste which is potentially processed to become livestock woof. Descriptive analysis was employed as a method of the study. Furthermore, Potato Dextrose Agar (PDA) was used as a medium for culturing and isolating the fungus. Dilution series and pour plate method were employed to isolate the fungus. And, Moist Chamber method was employed to identify it. In addition, Carboxy Methyl Cellulose (CMC) was used as medium to identify cellulolytic fungi. The process was carried out up to the level of genus based on macroscopic and microscopic characterization. 10 fungal isolates from the genus of Aspergillus sp 1, Aspergillus sp 2, Aspergillus sp 3, Aspergillus niger, Cladosporium sp, Mucor sp, Penicillium sp 1, Penicillium sp 2, Rhizopus sp and Trichoderma viride were yielded in this study. The results of examining cellulose enzyme activity revealed that 9 of 10 isolates of the fungus were capable of degrading cellulose. Isolates yielding the largest cellulose enzyme were Trichoderma viride, Penicillium sp 1, Cladosporium sp and Aspergillus niger.

description: This article reviews recent results of magnetotransport and magnetization measurements performed on highly oriented pyrolitic graphite (HOPG) and single crystalline Kish graphite samples. Both metal-insulator and insulator-metal transitions driven by magnetic field applied perpendicular to the basal planes of graphite were found and discussed in the light of relevant theories. The results provide evidence for the existence of localized superconducting domains in HOPG even at room temperature, as well as an interplay between superconducting and ferromagnetic correlations. We also present experimental evidence for the superconductivity occurrence in graphite-sulfur composites.

description: Poverty and food insecurity are some of the problems facing Nigerian population and governments at various levels today. Urban agriculture holds promise at solving these intractable problems. Urban agriculture is a practice that takes place in all urban centres, but existing studies have not succinctly examined the involvement of women in agriculture in small urban centres of Nigeria. The aim of this paper therefore, is to examine the motives behind involvement of women in urban agriculture in small agro-towns of Kwara State, Nigeria. A total of 1,801 women farmers were selected from 13 settlements cutting across 8 LGAs. Simple percentages, graphic illustrations, charts, tabulation and cross tabulation and stepwise multiple regression analysis were used to analyze the generated data. The study identifies three factors: food security, income supplement and accessibility to land, accounting for 98.6% as the best predictors of women involvement in urban agriculture. The study recommends that urban agriculture should be given official recognition by advocating for its support while women should be provided with financial resources to expand their farm plots.

description: Context: During the development process of a software program, regression testing is used to ensure that the correct behavior of the software is retained after updates to the source code. This regression testing becomes costly over time as the number of test cases increases and it makes sense to prioritize test cases in order to execute fault-detecting test cases as soon as possible. There are many coverage-based test case prioritization (TCP) methods that only use the code coverage data to prioritize test cases. By incorporating the fault-proneness estimations of code units into the coverage-based TCP methods, we can improve such techniques. Objective: In this paper, we aim to propose an approach which improves coverage-based TCP methods by considering the fault-proneness distribution over code units. Further, we present the results of an empirical study that shows using our proposed approach significantly improves the additional strategy, which is a widely used coverage-based TCP method. Method: The approach presented in this study uses the bug history of the software in order to introduce a defect prediction method to learn a neural network model. This model is then used to estimate fault-proneness of each area of the source code and then the estimations are incorporated into coverage-based TCP methods. Our proposed approach is a general idea that can be applied to many coverage-based methods, such as the additional and total TCP methods. Results: The proposed methods are evaluated on datasets collected from the development history of five real-world projects including 357 versions in total. The experiments show that using an appropriate bug history can improve coverage-based TCP methods.

The Three Faces of Privacy

description: Allow me to share a way of looking at the world, which helps to understand certain behaviours when addressing a complex topic like 'privacy".

 It basically follows the distinction, commonly made, between three levels of understanding the world: in a common sense way, scientific and philosophical.

 By introducing other elements in this world view, a more clear view emerges, in which people, in their daily routine, performing their tasks, are in their 'System 1' thinking, are curious, but when it comes to grasping a fairly new concept like 'privacy', people tend to have a wrong intuition and make wrong analyses. People, for instance, use free yet privacy invasive apps, because the apps are convenient, provide added value and everyone else uses them too.

 So, if you want to have a meaningful dialogue about 'privacy by design', make sure people get into their System 2 thinking first. Training & awareness sessions that allow for a broader look at things, deliberative and more logical. From this it follows that a policy is best formulated in a System 2 setting, but with the System 1 reality in mind. People do not make spontaneously the right choices in the daily hurly-burly, nor can they be expected to do so.

 And there's yet another level of wondering for the deep divers.

Inhomogeneous gas model for electron mobility in high density neon gas

description: Experimental studies of electron mobilities in Neon as a function of the gas density have persistently shown mobilities up to an order of magnitude smaller than expected and predicted. A previously ignored mechanism (gas in--homogeneity which is negligible in the thermal mobilities for He and other gases) is found to reproduce the observed Neon mobilities accurately and simply at five temperatures with just one variable parameter. Recognizing that a gas is not a homogeneous medium, a variation in local density combined with the quantum multi--scattering theory, shifts the energy and cross section -- which in turn changes the collision probability and finally the mobilities. A lower density where a momentum transfer interaction occurs moves the mobility strongly in the same direction as the anomalous experiments. By going backwards from the observed mobilities, the collision frequency at each temperature and density is made to reproduce the experimental data by looking for the local (as opposed to average) density at which the (rare) momentum transfer interactions occur. These density deviations give a picture of the size and behavior of the wave packets for electron motion which looks very much like the often discussed wave function collapse.

description: Cooperatives have been regarded as one of the main institutional machineries for empowering the economically weak members of the society. Despite the availability of cooperative societies, it appears that a significant proportion of rural women are either unaware of the existence of such co-operative societies or are lacking in the basic socioeconomic characteristics that form the prerequisite for participation in such activities. The study therefore examined the level of participation of women in cooperative organization and its determinants in the study area. The study was conducted in Yewa North Local Government area of Ogun State, south-west rainforest zone of Nigeria in 2011 using two stage sampling techniques to select 180 respondents. Descriptive statistics and Logit regression analysis were used to analyze the data generated. The results showed that pressure from household head, insufficient fund and low membership were found to be the major problems militating against women participation in cooperatives. Logit regression analysis revealed positive and significant relationships between variables such as education, years of business experience and forms of cooperative (producers and credit and thrift) and these variables were the major determinants of participation in cooperative society. Based on the findings of this study, it is recommended that any policy that will further increase the level of education of women would increase their participation in cooperative society.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: The cosmic-ray flux of positrons is measured with high precision by the space-borne particle spectrometer AMS-02. The hypothesis that pulsars and their nebulae can significantly contribute to the excess of the AMS-02 positron flux has been consolidated after the observation of a $γ$-ray emission at GeV and TeV energies of a few degree size around a few sources, that provide indirect evidence that electron and positron pairs are accelerated to very high energies from these sources. By modeling the emission from pulsars in the ATNF catalog, we find that combinations of positron emission from cataloged pulsars and secondary production can fit the observed AMS-02 data. Our results show that a small number of nearby, middle-aged pulsars, particularly B1055-52, Geminga (J0633+1746), and Monogem (B0656+14), dominate the positron emission, contributing up to 80\% of the flux at energies above 100 GeV. From the fit to the data, we obtain a list of the most important sources for which we recommend multi-wavelength follow-up observations, particularly in the $γ$-ray and X-ray bands, to further constrain the injection and diffusion properties of positrons.
