Subjects: subject: Social and Information Networks (cs.SI)

description: The widespread of Online Social Networks and the opportunity to commercialize popular accounts have attracted a large number of automated programs, known as artificial accounts. This paper focuses on the classification of human and fake accounts on the social network, by employing several graph neural networks, to efficiently encode attributes and network graph features of the account. Our work uses both network structure and attributes to distinguish human and artificial accounts and compares attributed and traditional graph embeddings. Separating complex, human-like artificial accounts into a standalone task demonstrates significant limitations of profile-based algorithms for bot detection and shows the efficiency of network structure-based methods for detecting sophisticated bot accounts. Experiments show that our approach can achieve competitive performance compared with existing state-of-the-art bot detection systems with only network-driven features.

description: We propose a design strategy - based on the coupling of spins, optical phonons, and strain - for systems in which magnetic (electric) phase control can be achieved by an applied electric (magnetic) field. Using first-principles density-functional theory calculations, we present a realization of this strategy for the magnetic perovskite EuTiO$_3$.

title: Nigerian cityscapes: reading socio-ecological concerns in Anglophone novels since 1954
Creators: name: Mazza, Ana Victoria
Publisher: name: University of Glasgow
Year: 2024

description: Some early Nigerian authors, such as Cyprian Ekwensi and Flora Nwapa, are well known for writing the city in the first decades after independence. Moreover, since the 1970s, Anglophone Nigerian urban literature has been experiencing an important growth (Griswold 2000). However, urban literature by Nigerian authors has not been sufficiently, nor consistently, studied; let alone in its ecological dimensions. The identified gap in ecocritical research on Nigerian urban fiction is consistent with a historical lack of attention to the city by both ecocritical and postcolonial studies, as well as with a marginalisation of postcolonial African cities within urban studies. Existing criticism is representative of the main trends in urban literary analysis conducted on Nigerian literature: studies that understand the city as opposed to nature and virtue; studies carried out from a political ecology and environmental justice framework; and those that focus on urban space, mobility, and identity in the city. 

The present project thus constitutes an attempt to address this gap by proposing a sustained comparative urban ecocritical examination of Anglophone Nigerian novels. Grounded in the environmental humanities, the study draws mainly on insights from Marxist and postcolonial ecologies, in conversation with urban ecocriticism (Bennett and Teague 1999), or cultural urban ecologies (Schliephake 2014). Through the interrogation of an extensive set of novels, the main aim is to analyse how nature and the environment are construed in the city, and what links are established, if any, between the social and environmental predicaments portrayed in the fictional urban landscapes. Close comparative readings of the selected primary texts are here organised thematically, allowing for the establishment of dialogical relationships between the selected works.

This thesis contends that, as Nigerian cultural products, the selected novels represent, to varying degrees, the interpenetration of human and nonhuman nature in the city. Instead of constructing the urban as a Human product opposed to and distinct from Nature, the works both expose the very real consequences of this distinction for human and nonhuman nature, and blur the boundaries between them, as well as sometimes exploring alternative solutions and/or (re)imagining relations beyond the divide. The texts thus undermine the conceptual separation of Society and Nature, which has historically justified the commodification of nature and the development of (neo)colonial capitalism. A thorough examination of these works demonstrates the sustained presence of environmental issues in Nigerian urban literature. Crucially, such an analysis can also influence the way cities are conceived of and understood, offering new insights into and alternative solutions to longstanding urban socio-ecological issues.

description: The emergence of the connected and automated vehicle (CAV) technology enables numerous advanced applications in our transportation system, benefiting our daily travels in terms of safety, mobility, and sustainability. However, vehicular communication technologies such as Dedicated Short-Range Communications (DSRC) or Cellular-Based Vehicle-to-Everything (C-V2X) communications unavoidably introduce issues like communication delay and packet loss, which will downgrade the performances of any CAV applications. In this study, we propose a consensus-based motion estimation methodology to estimate the vehicle motion when the vehicular communication environment is not ideal. This methodology is developed based on the consensus-based feedforward/feedback motion control algorithm, estimating the position and speed of a CAV in the presence of communication delay and packet loss. The simulation study is conducted in a traffic scenario of unsignalized intersections, where CAVs coordinate with each other through V2X communications and cross intersections without any full stop. Game engine-based human-in-the-loop simulation results shows the proposed motion estimation methodology can cap the position estimation error to 0.5 m during periodic packet loss and time-variant communication delay.

Analysis of chalcogenide-glass photonic crystal fibers

Supercontinuum generation

description: In this dissertation, we describe a theoretical study of chalcogenide-glass photonic crystal fiber designs. Light can propagate in these glasses in the wavelength region between 2 and 11 Âµm, in contrast to standard silica fiber in which light does not propagate beyond 2 Âµm. Consequently, they have important defense and biomedical applications. While silica-glass photonic crystal fibers have been extensively studied, that is not true for other glasses such as chalcogenide glasses. We have carried out this study in collaboration with researchers at the Naval Research Laboratory, who have provided the data that we use as input parameters to our simulations, as well as experimental results to compare to the simulations. In this dissertation, we first analyze leaky modes using traditional, one-dimensional slab waveguides. The reason for analyzing one-dimensional waveguides is that this analysis yields theoretical results that are of use in understanding the physics in the more complex geometry of two-dimensional waveguides. Next, we describe an investigation of the leakage loss from a finite number of air-hole rings in a photonic bandgap fiber as a function of the pitch and the refractive index. The leakage loss is due to incomplete mode confinement. It is shown that for a refractive index equal to 2.4, corresponding to chalcogenide glass at a wavelength of 4 Âµm, the loss is minimal when the air-hole-diameter-to-pitch ratio equals 0.8. This result contrasts strongly with analogous results for silica fibers in which the leakage loss is minimized by making the air-hole-diameter-to-pitch ratio approach as close to 1.0 as possible. In addition to minimizing the leakage loss, the core geometry is optimized for air-core photonic bandgap fibers to decrease the effect of coupling losses to surface modes. Finally, the nonlinearity is characterized and used in simulations to study supercontinuum generation in chalcogenide fibers. The nonlinearities that must be included are the Kerr and Raman effects. After verifying that the simulation code reproduces the spectrum that was observed in experimental studies of infrared supercontinuum generation from 2.1 to 3.2 Âµm, we then used the code to predict that a bandwidth of more than 4 Âµm can be generated using an As2Se3-based chalcogenide photonic crystal fiber with an air-hole-diameter-to-pitch ratio of 0.4 and a pitch of 3 Âµm.

description: We present an analysis leading to a conjecture on the exact location of the multicritical point in the phase diagram of spin glasses in finite dimensions. The conjecture, in satisfactory agreement with a number of numerical results, was previously derived using an ansatz emerging from duality and the replica method. In the present paper we carefully examine the ansatz and reduce it to a hypothesis on analyticity of a function appearing in the duality relation. Thus the problem is now clearer than before from a mathematical point of view: The ansatz, somewhat arbitrarily introduced previously, has now been shown to be closely related to the analyticity of a well-defined function.

Intimate partner violence recidivism over an 8-year follow-up

Publisher: name: Maryland Shared Open Access Repository
Year: 2014
Subjects: domestic violence

description: The study examined the criminal behavior of men who sought treatment for intimate partner violence (IPV). Criminal offenses were coded for the 5 years prior to treatment initiation and the 8 years after treatment initiation into three categories: Domestic Abuse, General Violence, and Other Protection Order Involvement.   Of 115 men, 85 (73.91%) had no incidents coded as Domestic Abuse during the 8-year follow-up period.  Overall, there were significant reductions in Domestic Abuse and General Violence between the two time periods.  It was observed that 12 men (10.4%) accounted for 60% of the incidents of Domestic Abuse recidivism.  The main study hypothesis was that borderline and antisocial personality characteristics would be predictive of criminal recidivism after treatment initiation. Counter to hypotheses, these personality characteristics were not predictive of criminal recidivism in the majority of analyses. Consistent with the hypothesis, self-report ratings of antisocial personality characteristics, assessed at treatment program intake, were significantly related to General Violence during the 8-year follow-up.  When incidents of General Violence and Domestic Abuse recidivism were combined, this variable was also significantly related to previous self-ratings of antisocial personality characteristics.  Self-reports of borderline personality characteristics were not significantly related to any of the criminal recidivism variables.  The findings suggest that the majority of men seeking treatment for IPV have no criminal recidivism after treatment initiation, but that a small subsample of men maintain or increase the frequency of criminal behavior after treatment initiation.  Future studies will need to examine other individual-level characteristics that may distinguish these men so that treatment can better target the risk factors of IPV recidivism.

description: Histopathology image embedding is an active research area in computer vision. Most of the embedding models exclusively concentrate on a specific magnification level. However, a useful task in histopathology embedding is to train an embedding space regardless of the magnification level. Two main approaches for tackling this goal are domain adaptation and domain generalization, where the target magnification levels may or may not be introduced to the model in training, respectively. Although magnification adaptation is a well-studied topic in the literature, this paper, to the best of our knowledge, is the first work on magnification generalization for histopathology image embedding. We use an episodic trainable domain generalization technique for magnification generalization, namely Model Agnostic Learning of Semantic Features (MASF), which works based on the Model Agnostic Meta-Learning (MAML) concept. Our experimental results on a breast cancer histopathology dataset with four different magnification levels show the proposed method's effectiveness for magnification generalization.

description: We present a phenomenological Lagrangian and Poisson brackets for obtaining nondissipative hydrodynamic theory of supersolids. A Lagrangian is constructed on the basis of unification of the principles of non-equilibrium thermodynamics and classical field theory. The Poisson brackets, governing the dynamics of supersolids, are uniquely determined by the invariance requirement of the kinematic part of the found Lagrangian. The generalization of Lagrangian is discussed to include the dynamics of vortices. The obtained equations of motion do not account for any dynamic symmetry associated with Galilean or Lorentz invariance. They can be reduced to the original Andreev-Lifshitz equations if to require Galilean invariance. We also present a relativistic-invariant supersolid hydrodynamics, which might be useful in astrophysical applications.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A method is presented which allows the exact construction of conserved (i.e. divergence-free) current vectors from appropriate sets of multipole moments. Physically, such objects may be taken to represent the flux of particles or electric charge inside some classical extended body. Several applications are discussed. In particular, it is shown how to easily write down the class of all smooth and spatially-bounded currents with a given total charge. This implicitly provides restrictions on the moments arising from the smoothness of physically reasonable vector fields. We also show that requiring all of the moments to be constant in an appropriate sense is often impossible; likely limiting the applicability of the Ehlers-Rudolph-Dixon notion of quasirigid motion. A simple condition is also derived that allows currents to exist in two different spacetimes with identical sets of multipole moments (in a natural sense).

"An intertidal voyage" : a qualitative study of six children’s understanding of the physical adaptations and survival behaviours of intertidal organisms
Creators: name: Scott, Sandra A.
Publisher: name: University of British Columbia
Year: 2009

description: An Intertidal Voyage is a case study of children's understanding of the survival behaviours and physical adaptations of intertidal organisms. The intent of the study was to analyze and interpret student language and to document the changes in student knowledge as they explored the seashore. Six students participated in three individual interviews and nine group field trips. The first interview determined the student's prior seashore knowledge and interviews two and three revealed changes in their knowledge. The field trips enabled the students to explore, investigate, observe, and discuss the inhabitants of the intertidal zone. The student's use of descriptive language and metaphor was recorded during the interviews and field trips and is presented through the students' styles of knowing of aesthete, scientist, and warrior. The findings of "An Intertidal Voyage" showed that field trips enhance student learning. The students employed descriptive language and metaphor to express their seashore knowledge and retained their preferred style of knowing throughout the study. The study shows that students used their previous knowledge as a bridge to new ideas. The findings also highlight the importance of a facilitator in experiential learning and demonstrate that students learn in social situations as they interpret new knowledge and exchange ideas through observation and discussion. As the study progressed the students developed a sense of environmental stewardship for the seashore and expressed an awareness and appreciation of the inhabitants of the intertidal zone.
Synthetic studies towards the pyrrolo [2,1-c][1,4] benzodiazepine natural products

description: The work detailed in this thesis describes the development of a suitable synthetic strategy for the synthesis of pyrrolo[2,1-c][1,4]benzodiazepine (PBD) natural products such as anthramycin (1), porothramycin (2) and sibiromycin (3) - antitumour antibiotics which are capable of covalently binding to DNA and exhibit potent in vitro and in vivo cytotoxicity. The synthetic sequence involved introduction of the key stereocentre by asymmetric alkylation and construction of the C-ring dihydropyrrole moiety by ring-closing enyne metathesis (RCEYM). Studies into the metathesis rearrangement involved investigations into the employment of relay-ring closing metathesis (RRCM) on substrate A (R = CO2Allyl) to aid delivery of the chosen catalyst. However, these attempts proved unsuccessful and the metathesis substrate was redesigned to include an allylic alcohol moiety (A; R = CH2OH) which led to the successful metathesis rearrangement and delivered the dihydropyrrole moiety with an allylic alcohol side chain (B; R = CH2OH). Following the metathesis rearrangement, subsequent oxidation of the allylic alcohol moiety (B; R = CH2OH) proved difficult and thus, was extensively investigated to provide a suitable protocol for the synthesis of the required dimethyl amide (B; R = CONMe2) associated with porothramycin (2). A brief investigation into appropriate nitrogen protecting groups led to the use of the 2-trimethylsilylethanesulfonyl (SES) protecting group. Unfortunately, there were problems related to the removal of the SES group from the dihydropyrrole B (PG2 = SES; R = CONMe2) and this led to the development of substrate C which successfully participated in an intramolecular substitution upon SES deprotection to give amide D. Studies into the conversion of this compound to the desired natural product by way of an oxidation and Staudinger reaction were also undertaken, however, results obtained could not conclusively determine that porothramycin (2) had been synthesised. The sum of the efforts presented in this thesis, whilst not delivering a total synthesis of the target compound (2), does provide a suitable and feasible protocol with which to synthesise the target natural product (2) as well as other compounds in the same class (1 & 3).

The spreading of the atomic cloud is avoided by an adequate tuning of the scattering length. We also discuss other variations that offer new possibilities of robust control of atomic solitons. Our numerical results show that this cold matter accelerator is easily accessible in the frame of current experiments.

description: Nowadays, enterprises are confronted to growing needs for traceability, product genealogy and product life cycle management. To meet those needs, the enterprise and applications in the enterprise environment have to manage flows of information that relate to flows of material and that are managed in shop floor level. Nevertheless, throughout product lifecycle coordination needs to be established between reality in the physical world (physical view) and the virtual world handled by manufacturing information systems (informational view). This paper presents the "Holon" modelling concept as a means for the synchronisation of both physical view and informational views. Afterwards, we show how the concept of holon can play a major role in ensuring interoperability in the enterprise context.

description: In this contribution we discuss the role disordered (or random) systems have played in the study of non-Gibbsian measures. This role has two main aspects, the distinction between which has not always been fully clear: 1) {\em From} disordered systems: Disordered systems can be used as a tool; analogies with, as well as results and methods from the study of random systems can be employed to investigate non-Gibbsian properties of a variety of measures of physical and mathematical interest. 2) {\em Of} disordered systems: Non-Gibbsianness is a property of various (joint) measures describing quenched disordered systems. We discuss and review this distinction and a number of results related to these issues. Moreover, we discuss the mean-field version of the non-Gibbsian property, and present some ideas how a Kac limit approach might connect the finite-range and the mean-field non-Gibbsian properties.

description: The new generation internal beam dump of the Super Proton Synchrotron (SPS) at CERN will have to dissipate approximately 270 kW of thermal power, deposited by the primary proton beam. For this purpose, it is essential that the cooling system features a very efficient heat evacuation. Diffusion bonding assisted by Hot Isostatic Pressing (HIP) was identified as a promising method of joining the cooling circuits and the materials of the dump's core in order to maximise the heat transfer efficiency. This paper presents the investigation of HIP assisted diffusion bonding between two CuCr1Zr blanks enclosing SS 316L tubes and the realisation of a real size prototype of one of the dump's cooling plate, as well as the assessments of its cooling performance under the dumps most critical operational scenarios. Energy-dispersive X-ray (EDX) spectroscopy, microstructural analyses, measurements of thermal conductivity and mechanical strength were performed to characterize the HIP diffusion bonded interfaces (CuCr1Zr-CuCr1Zr and CuCr1Zr-SS316L). A test bench allowed to assess the cooling performance of the real size prototype. At the bonded interface, the presence of typical diffusional phenomena was observed. Moreover, measured tensile strength and thermal conductivity were at least equivalent to the lowest ones of the materials assembled and comparable to its bulk properties, meaning that a good bonding quality was achieved. Finally, the real size prototype was successfully tested with an ad-hoc thermal test bench and with the highest operational thermal power expected in the new generation SPS internal beam dump.

description: Economic activities are unevenly distributed in space. The economic literature has extensively investigated the potential reasons behind the emergence of cities and local specializa- tion, on one hand, and foreign trade and investment patterns, on the other. These essays aim to analyze some of the compo- nents explaining the spatial variation of economic activities, leveraging an extensive amount of firm-level data. First, I in- vestigate the interplay between regional productivity dispari- ties and local agglomeration advantages. Although I find evi- dence for agglomeration advantages stemming within Italian firms’ clusters, I find them to be much smaller than the pro- ductivity premium for firms located in northern Italy. Sec- ond, I investigate the rationale for the ownership chains de- veloped by multinational enterprises across different national borders. Based on the insight that the placement of subsidiaries along ownership chains is driven by the existence of commu- nication costs to transmit management decisions, I develop a theoretical model for corporate control where parent com- panies can delegate monitoring activities to middlemen sub- sidiaries that are located in intermediate jurisdictions. I de- rive a two-step empirical strategy enabling the structural es- timation of a gravity equation for foreign investments. Third, I investigate the ability of European Union regions to retain foreign investments, evaluating how crucial regional charac- teristics, such as an R&D-friendly economic environment and good local institutions, affect the life duration of companies targeted by foreign investments.

description: Personality, alcohol expectancies, and drinking motives have been identified as key factors affecting alcohol use and drinking patterns in college populations (Cooper et al., 2000; Katz et al., 2000; Kuntsche et al., 2008). To date, most research has focused on the mediating effects of motives to drink, rather than expectancies of drinking, on the relation between personality and alcohol use. The current study examined the mediating effects of both alcohol expectancies and motives on the relation between personality and alcohol use, specifically looking at the strength of these mediating variables in a sample of full-time college students. Two-hundred and seventy five undergraduate students completed an online questionnaire assessing personality (extraversion and neuroticism), alcohol expectancies (positive and negative), drinking motives (enhancement, coping, and social), and patterns of alcohol use (frequency and intensity). Results found small-to-moderate relations among study variables, with limited mediating effects of expectancies and motives.

description: Because of the long Fermi wavelength of itinerant electrons, the quantum limit of elemental bismuth (unlike most metals) can be attained with a moderate magnetic field. The quantized orbits of electrons shrink with increasing magnetic field. Beyond the quantum limit, the circumference of these orbits becomes shorter than the Fermi wavelength. We studied transport coefficients of a single crystal of bismuth up to 33 tesla, which is deep in this ultraquantum limit. The Nernst coefficient presents three unexpected maxima that are concomitant with quasi-plateaus in the Hall coefficient. The results suggest that this bulk element may host an exotic quantum fluid reminiscent of the one associated with the fractional quantum Hall effect and raise the issue of electron fractionalization in a three-dimensional metal.

description: We study the electron energy spectra of two powerful solar flares SOL2003-10-28T 11:06:16 (GOES class X17.2) and SOL2002-07-23T00:18:16 (X4.8) on the basis of HXR and gamma-ray spectra obtained from RHESSI data. Electron-electron (e-e) bremsstrahlung makes a significant contribution to the X-ray flux at energies above 500 keV. In X-ray flux calculations different electron pitch-angle distributions were considered: quasi-transverse and quasi-longitudinal. It was shown that breaks in hard X-ray spectra occur on energies $ε\approx100$ keV with photon spectral-index difference $Δγ\ge 1$ in the case of quasi-longitudinal anisotropy and hard power-law electron energy spectra. We deduce the parameters of non-thermal electrons energy spectra from RHESSI data for the extreme solar flares of 2003 October 28 and 2002 July 23. After including e-e bremsstrahlung, the non-thermal electrons energy spectra obtained in the thick-target model can be fitted using power-law with spectral index $δ\approx 5$. For the 2002 July 23 flare, there is a pronounced asymmetry towards the southern footpoint, starting from energies above 100 keV. The separation of HXR sources at energies above 100 keV may be related to a feature of relativistic electron transport in flaring loops.

description: Time-varying data is huge and contains specific features of interest to an application expert. Standard techniques for visualizing time-varying data such as snapshots and animations are limited in their ability to convey change and draw the user's attention to regions of; interest. Art-inspired techniques are presented to provide temporal context to the domain expert. I present novel visualization techniques that convey change over time in a single image. Illustrators convey change over time using illustrative cues. Time-varying data, in which three-dimensional features are moving over time, can be effectively visualized using illustrative techniques such as speedlines, flow ribbons, strobe silhouettes and opacity based; techniques. I applied these techniques to computational fluid dynamics data and; evaluated the effectiveness of our techniques with the help of a formal user study. The illustration-inspired techniques were also applied to the field of atmospheric physics, where I generated novel hurricane visualizations that allowed collaborators to obtain insight into; the evolution and intensification of a hurricane.; For effectively visualizing time-varying data, such as infant mortality over eight years or global rainfall over an entire century, we developed a novel pointillism-based technique. This technique was inspired by paintings by Seurat, applied the visual color blending theory to place brush strokes close to each other. We applied techniques from pointillistic; paintings to convey variability in time-varying data and to convey trends over time in a single image. The formal user evaluation conducted to evaluate these techniques gave us insight into the strengths of our techniques and led us to the result that users though correct were less confident of their answers as compared to snapshots-based and animation-based techniques.

description: Advancements in information and communications technologies (ICTs) have enabled many developing countries to exploit their comparative advantage in services exports. In developing regions, South Asia has taken the lead in the export of modern services including computer, IT and professional services. During the last decade, South Asia has been able to grow at a reasonable average annual growth rate of almost 7 percent. This growth rate has emanated from the strong performance of South Asia's services sector both in terms of domestic output and exports. This path of service-led growth in South Asia is in sharp contrast to East Asia's high growth, which has been possible through its manufacturing based export orientation. This thesis provides an exploratory analysis of service-led growth in South Asia. First, it explains the growing role of services in the economic growth and development of South Asia, and provides a comparative evaluation of the growth experience of South Asia and East Asia. Second, growth of modern services exports from developing countries are explained and supported by the theoretical and empirical literature, to analyze the different sources of these exports. Third, it explains the growth of modern services exports of South Asia and the export performance of selected modern services of the region, in a global context. Fourth, it provides an objective analysis of the differences in technologies and export potential of selected high performing South and East Asian countries with the developed world. Finally, it examines the intersectoral relationship between the services and agriculture and manufacturing sectors. The study contributes to the debate on the service-led growth path and export orientation, and the findings have important policy implications. The results show that despite the significant growth of modern services exports from South Asia, the region has large potential to further increase these exports. This potential can provide sustainability to the current services dominated growth in the region. Another important implication for policy makers is that sustained growth of high skilled graduates and high end ICT infrastructure are essential for the continuity of modern services export growth. Finally, performance of manufacturing and agriculture sectors are, to some extent, prerequisites for overall services sector growth. -- provide by Candidate.
An Internet-Based Study of Associations Between Personality, Spirituality, and Trait Mindfulness

description: The recent surge in interest in mindfulness-based interventions has not been paralleled by equally extensive research into the nature of mindfulness.  It has yet to be definitively determined how one's innate characteristics, such as personality or quality of life, might impact one's level of mindfulness.  Similarly, though researchers have worked to separate mindfulness interventions from their religious roots, little is known about whether mindfulness may indeed vary due to one's religious affiliation or practice.  This study, conducted entirely online via surveymonkey.com, utilized data collected from 291 individuals recruited from social media and online classified sites.  Self-report measures assessed participant religious orientation and frequency of practice, dimensions of personality, trait mindfulness, and quality of life variables such as level of stress and quality of sleep.  Analyses examined whether mean mindfulness varied between religious groupings, whether religiosity, quality of life, and personality were significant predictors of mindfulness, and whether sex moderated the relations between personality and mindfulness.  Differences in mindfulness scores were significantly related to personality dimensions, quality of life variables, and the sex of the respondent.  These results suggest that further research is needed to explore how individuals vary on self-reported levels of mindfulness and how such variation might impact mindfulness-based interventions.

description: We develop a full multichannel spin model in momentum space to investigate three-body recombination of identical alkali-metal atoms colliding in a magnetic field. The model combines the exact three-atom spin structure and realistic pairwise atom-atom interactions. By neglecting the interaction between two particles when the spectating particle is not in its initial spin state we arrive at an approximate model. With this approximate model we achieve excellent agreement with the recent precise measurement of the ground Efimov resonance position in potassium-39 close to 33.58 G [Chapurin $et$ $al$., Phys. Rev. Lett. 123, 233402 (2019)]. We analyze the limitations of our approximation by comparing to the numerical results for the full system and find that it breaks down for Feshbach resonances at larger magnetic fields in the same spin channel. There the relevant three-body closed channel thresholds are much closer to the open channel threshold, which enhances the corresponding multichannel couplings. Therefore the neglected components of the interaction should be included for those Feshbach resonances.

description: Lin and Yang's upper bound E_Q <= cQ^(3/4) of the least static energy E_Q of the Faddeev model in a sector with a fixed Hopf index Q is investigated. By constructing an explicit trial configuration for the Faddeev field n, a possible value of the coefficient c is obtained numerically, which is much smaller than the value obtained quite recently by analytic discussions.
