description: Structural and thermal characteristics of crystalline ropes of single-wall carbon nanotubes (SWCNTs) are investigated. Novel crystalline ropes of polygonized SWCNTs produced by laser irradiation exhibit rounded-hexagonal cross sections in contrast to earlier observations of circular tubes. Extensive molecular dynamics (MD) simulations lead to several metastable structures of the lattice characterized by different tube cross sections, hexagonal, rounded-hexagonal and circular, and increasing cell volume. The competition between different tube shapes is analyzed and compared to experiments. On the other hand, bundles of SWCNTs coalesce forming multiwall carbon nanotubes (MWCNTs) under thermal treatment at high temperatures. Extensive MD simulations confirm the SW-to-MW transformation and suggest the physical patching--and--tearing mechanism underlying the concerted coalescence of the tubes.

description: The aerial performance of flying insects ultimately depends on how flapping wings interact with the surrounding air. It has previously been suggested that the wing's three-dimensional camber and corrugation help to stiffen the wing against aerodynamic and inertial loading during flapping motion. Their contribution to aerodynamic force production, however, is under debate. Here, we investigated the potential benefit of three-dimensional wing shape in three different-sized species of flies using models of micro-computed tomography-scanned natural wings and models in which we removed either the wing's camber, corrugation, or both properties. Forces and aerodynamic power requirements during root flapping were derived from three-dimensional computational fluid dynamics modelling. Our data show that three-dimensional camber has no benefit for lift production and attenuates Rankine–Froude flight efficiency by up to approximately 12% compared to a flat wing. Moreover, we did not find evidence for lift-enhancing trapped vortices in corrugation valleys at Reynolds numbers between 137 and 1623. We found, however, that in all tested insect species, aerodynamic pressure distribution during flapping is closely aligned to the wing's venation pattern. Altogether, our study strongly supports the assumption that the wing's three-dimensional structure provides mechanical support against external forces rather than improving lift or saving energetic costs associated with active wing flapping.

description: An efficient management system and leadership body is one of the key requirements for a road safety improvement program. In low- and middle-income countries, the organizational structure of the management system may suffer from deficiencies weakening the institutional functions across key road safety players. Hence, it is necessary to form an inner- and inter-organization evaluation framework encompassing all the processes, events, dependencies, and causation among road safety players. In this paper, a (three-stage) system thinking approach is developed to evaluate the behavior of inter-organizational complex system and to determine major deficiencies in the role of the road safety lead agency. The first stages of the system thinking approach starts with drawing diagrams (i.e. multiple-effect and multiple-criteria trees) that allows identifying the chains of reasoning behind events or consequences. The next stage of the system thinking approach embodies the analytic network process (ANP), an advanced multi-criteria decision-making technique, which handles the lead agency capacity evaluation and helps to determine how and by what magnitude any of the players can affect the national road safety. The proposed method applies to the case of Iran, a middle-income developing country in the Middle East. Since in Iran, the Road Safety Commission (RSC) has been established as the lead agency, it was expected that RSC owns the greatest influence on the status of road safety. However, our results show that the overall influence of RSC on road safety is far less than what was expected. Subsequently, a supplementary procedure is proposed to specify institutional reforms in order to avoid such organizational inefficiencies.

description: We report the discovery of seven high proper motion stars with proper motions between about 0.7 and 2.2 arcsec/yr. They were detected in an archival search using multi-epoch positions in the optical SuperCOSMOS Sky Surveys and in the near-infrared sky surveys 2MASS and DENIS. The star with the largest proper motion, is spectroscopically classified as a very nearby (d=8pc) M5.5 dwarf with Galactic thin disk kinematics. A second star with about 2 arcsec/yr proper motion, is still lacking spectroscopic confirmation but can be classified from photometry as thick disk M3.5 dwarf. Three objects turn out to be cool subdwarf members of the Galactic thick disk or halo, including the first sdM9.5 object, which represents the currently coolest known M subdwarf, another ultra-cool subdwarf, of spectral type sdM7.0 as well as an earlier type (sdM1.5) star. The latter has an extremely large space velocity with clear halo kinematics. Two objects show featureless spectra typical of cool white dwarfs. One of them is probably a very nearby (d~4pc) thin disk object and may be the nearest isolated white dwarf, the other one has thick disk kinematics.

description: Quasi-biennial oscillation (QBO) of solar magnetic activities is intrinsic to dynamo mechanism, but still far from fully understood. In this work, the phase and amplitude asymmetry of solar QBO of Halpha flare activity in the northern and southern hemispheres is studied by the ensemble empirical mode decomposition, the cross-correlation analysis, and the wavelet transform technique. The following results are found: (1) solar QBO of Halpha flare index in the two hemispheres has a complicated phase relationship, but does not show any systematic regularity; (2) the solar cycle mode of solar Halpha flare index in the northern hemisphere generally leads that in the southern one by 9 months for the time interval from 1966 to 2014. The possible origin of these results is discussed.

description: Faculty and researchers, mostly well-trained, usually fill managerial positions at universities. Still, they do not have formal management training. This qualitative study examined the managerial competencies of 11 university firstline managers. Using Kurz and Bartram’s Great Eight Competency Theory (2002) for the thematic analysis of the interview transcripts, most of the respondents exhibited all eight competencies. However, they differed in terms of manifestations. A typology of academic administrators was developed based on the eight competencies, namely: (1) delegator, (2) accommodator, (3) director, and (4) initiator. Further quantitative research is recommended to refine this typology. Likewise, to develop current and potential administrators, this paper recommends training and workshops on human resources management, communication, conflict resolution, relationship building and maintenance, resource management, mentoring, project and research management, situational analysis, innovation, and the processes of the university.

description: The tadpole cancellation in the unoriented Liouville theory is discussed. Using two different methods -- the free field method and the boundary-crosscap state method, we derive one-loop divergences. Both methods require two D1-branes with the symplectic gauge group to cancel the orientifold tadpole divergence. However, the finite part left is different in each method and this difference is studied. We also discuss the validity of the free field method and the possible applications of our result.

Ένα από τα πιο σημαντικά μέτρα για την αντιμετώπιση της πανδημίας ήταν η κοινωνική αποστασιοποίηση η οποία έπληξε σοβαρά τις κοινωνικές, επαγγελματικές, εργασιακές και άλλες κοινότητες. Ο σκοπός αυτής της εργασίας είναι να μελετήσει αν η πανδημία αυτή έχει επίδραση και στην κοινότητα του ελεύθερου λογισμικού, ανοιχτού κώδικα. Για αυτό το σκοπό, μελετήθηκε η επίδραση της πανδημίας στην συμμετοχή των χρηστών στην ανάπτυξη ενός έργου ανοικτού κώδικα, του WordPress Gutenberg το οποίο βρίσκεται στην πλατφόρμα του GitHub. Με την χρήση της γλώσσας προγραμματισμού Python, διενεργήθηκε η συλλογή των δεδομένων από το API του GitHub και έγινε η κατάλληλη επεξεργασία αυτών, έτσι ώστε να διαπιστωθεί αν οι χρήστες συμμετείχαν περισσότερο στην εξέλιξη του Gutenberg κατά τη διάρκεια της πρώτης και της δεύτερης καραντίνας που επιβλήθηκαν κατά τα έτη 2020 και 2021. Τέλος, η ανάλυση συναισθήματος που διενεργήθηκε στα σχόλια των χρηστών με δύο εργαλεία ανάλυσης, έχει σαν στόχο να προσδιορίσει αν υπήρχε συσχέτιση της καραντίνας με την αύξηση των θετικών σχολίων τα οποία αναρτήθηκαν κατά τη διάρκεια που επιβλήθηκαν οι καραντίνες
description: Since the beginning of 2020, the world has been faced with an unprecedented situation and has been called upon to deal with particularly difficult situations caused by the outbreak of the COVID-19 virus. One of the most important measures to deal with the pandemic was social alienation which severely affected the social, professional, work and other communities. The purpose of this thesis is to investigate whether this pandemic also has an impact on the free software of open-source community. For this purpose, an investigation was contacted in order to find out the impact of the pandemic on user participation in the development of an open-source project, WordPress Gutenberg, which is located on the GitHub platform. Using the Python programming language, the data was collected from the GitHub API and properly processed to determine if users were more involved in the Gutenberg development during the first and second quarantines imposed during the years 2020 and 2021. Finally, the sentiment analysis conducted in the comments of users with two analysis tools, aims to determine whether there was a correlation between the increase in positive comments posted during the quarantine

description: Takada et al. have reported superconductivity in layered $Na__x CoO_2.yH_2O$ ($T_c \approx5 K$) and more recently Wen et al. in $A_xCoO_{2+δ}$ ($A = Na,K$)(\tc$\approx~31 K$). We model a reference neutral \cob layer as an orbitally non-degenerate spin-\half antiferromagnetic Mott insulator on a triangular lattice and $Na__x CoO_2.yH_2O$ and $A_xCoO_{2+δ}$ as electron doped Mott insulators described by a t-J model. It is suggested that at optimal doping chiral spin fluctuations enhanced by the dopant dynamics leads to a d-wave superconducting state. A chiral RVB metal, a PT violating state with condensed RVB gauge fields, with a possible weak ferromagnetism and low temperature p-wave superconductivity are also suggested at higher dopings.

description: Ο Friedrich Nietzsche ήταν αναμφισβήτητα ο πιο ενδιαφέρον κριτικός και μάρτυρας της πορείας του Richard Wagner και μια προσωπικότητα που συνδέθηκε άμεσα με το έργο του συνθέτη. Σε κάθε περίπτωση κανένας άλλος διανοούμενος δεν έδωσε τόση προσοχή στο έργο αυτό. Και τέλος είναι μοναδική σε όλη την ιστορία της ευρωπαϊκής κουλτούρας η συνάντηση αυτή, ενός αληθινά μεγάλου μουσικοσυνθέτη και ενός φιλοσόφου. Δεδομένης της μοναδικής αυτής σχέσης ανάμεσα στον Wagner και στον Nietzsche μια ανάλυση των ζητημάτων και των προβλημάτων που ανέκυψαν είναι αναπόφευκτη αν κάποιος επιθυμεί την πλήρη κατανόηση της σημασίας του συνθέτη ή της κληρονομιάς του φιλοσόφου.
description: Friedrich Nietzsche was undoubtedly the most interesting critic and witness to Richard Wagner's course and a personality directly associated with the composer's work. In any case, no other intellectual paid so much attention to this work. And finally, this meeting of a truly great composer and a philosopher is unique in the whole history of European culture. Given this unique relationship between Wagner and Nietzsche, an analysis of the issues and problems that have arisen is inevitable if one wants to fully understand the significance of the composer or the philosopher's legacy.

description: We study the effect of a magnetic flux in a 1D disordered wire with long range hopping. It is shown that this model is at the metal-insulator transition (MIT) for all disorder values and the spectral correlations are given by critical statistics. In the weak disorder regime a smooth transition between orthogonal and unitary symmetry is observed as the flux strength increases. By contrast, in the strong disorder regime the spectral correlations are almost flux independent. It is also conjectured that the two level correlation function for arbitrary flux is given by the dynamical density-density correlations of the Calogero-Sutherland (CS) model at finite temperature. Finally we describe the classical dynamics of the model and its relevance to quantum chaos.

description: The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GCs) has investigated multiple stellar populations by means of the "chromosome map" (ChM) diagnostic tool that maximises the separation between stars with different chemical composition. One of the most challenging features revealed by ChMs analysis is the apparent inhomogeneity among stars belonging to the first population, a phenomenon largely attributed to He variations. However, this explanation is not supported by the uniformity in p-capture elements of these stars. The HST survey has revealed that the GC NGC 3201 shows an exceptionally wide coverage in the Delta(F275W,F814W) parameter of the ChM. We present a chemical abundance analysis of 24 elements in 18 giants belonging to the first population of this GC, and having a wide range in Delta(F275W,F814W). As far as the p-capture elements are concerned, the chemical abundances are typical of 1G stars, as expected from the location of our targets in the ChM. Based on radial velocities and chemical abundances arguments, we find that the three stars with the lowest Delta(F275W,F814W) values are binary candidates. This suggests that, at least those stars could be explained with binarity. These results are consistent with evidence inferred from multi-band photometry that evolved blue stragglers populate the bluest part of the 1G sequence in the ChM. The remaining 15 spectroscopic targets show a small range in the overall metallicity by ~0.10 dex, with stars at higher Delta(F275W,F814W) values having higher absolute abundances. We suggest that a small variation in metals and binarity govern the color spread of the 1G in the ChM, and that evolved blue stragglers contribute to the bluest tail of the 1G sequence.

description: This letter analyzes the performances of a simple reconstruction method, namely the Projected Back-Projection (PBP), for estimating the direction of a sparse signal from its phase-only (or amplitude-less) complex Gaussian random measurements, i.e., an extension of one-bit compressive sensing to the complex field. To study the performances of this algorithm, we show that complex Gaussian random matrices respect, with high probability, a variant of the Restricted Isometry Property (RIP) relating to the l1 -norm of the sparse signal measurements to their l2 -norm. This property allows us to upper-bound the reconstruction error of PBP in the presence of phase noise. Monte Carlo simulations are performed to highlight the performance of our approach in this phase-only acquisition model when compared to error achieved by PBP in classical compressive sensing.

Atrial Fibrillation and Oral Anticoagulation : The Importance of Guideline-Adherence and Clarity
Creators: name: Hestvik, Lukas
Publisher: name: The University of British Columbia
Year: 2018

description: Atrial fibrillation (AF) is the most prevalent arrhythmia, affecting 350,000 Canadians. AF can impact quality of life, mortality, and morbidity. The most serious complication of AF is thrombo-embolic stroke, and is responsible for 20 to 30% of all strokes. Oral anticoagulation (OAC) of AF can decrease the risk of stroke by 64%. Risk stratification tools have been developed and incorporated into guidelines to assist practitioners in providing the most appropriate OAC treatment for each individual patient. However, research has indicated that there is a lack of adherence by practitioners to guideline-based oral anticoagulation therapy. Until recently, warfarin was the anticoagulant of choice for nonvalvular AF. Warfarin is inexpensive, widely available, and also has the benefit of having widely available reversal agents. More recently, direct oral anticoagulants (DOACs) have been approved for the treatment of nonvalvular AF. In clinical trials DOACs have demonstrated to be as safe and effective in preventing strokes compared to warfarin if not more. They are also more convenient for patients as they have much fewer drug and food interactions and do not require rigorous routine blood monitoring. However, DOACs are more expensive than warfarin and previously did not have reversal agents available. Dabigatran (a DOAC), now has a reversal agent, and other reversal agents are being developed for the rest of the DOACs. In this paper, I will review three guidelines for oral anticoagulation treatment in nonvalvular AF. I will discuss potential reasons for practitioners’ lack of adherence to these guidelines. And finally, I will explain the pocket guide that I will create to assist new practitioners in treating AF. By summarizing different guidelines into one pocket guide, I will assist new practitioners in having the richest source of information in one location, as opposed to having to consult different guidelines and potentially AF and OAC becoming confused as to what is best practice. The ultimate goal of this project is to decrease the number of AF-induced strokes.

description: To develop low-moment, low-damping metallic ferromagnets for power-efficient spintronic devices, it is crucial to understand how magnetic relaxation is impacted by the addition of nonmagnetic elements. Here, we compare magnetic relaxation in epitaxial Fe films alloyed with light nonmagnetic elements of V and Al. FeV alloys exhibit lower intrinsic damping compared to pure Fe, reduced by nearly a factor of 2, whereas damping in FeAl alloys increases with Al content. Our experimental and computational results indicate that reducing the density of states at the Fermi level, rather than the average atomic number, has a more significant impact in lowering damping in Fe alloyed with light elements. Moreover, FeV is confirmed to exhibit an intrinsic Gilbert damping parameter of $\simeq$0.001, among the lowest ever reported for ferromagnetic metals.

description: The aerial performance of flying insects ultimately depends on how flapping wings interact with the surrounding air. It has previously been suggested that the wing's three-dimensional camber and corrugation help to stiffen the wing against aerodynamic and inertial loading during flapping motion. Their contribution to aerodynamic force production, however, is under debate. Here, we investigated the potential benefit of three-dimensional wing shape in three different-sized species of flies using models of μCT-scanned natural wings and models in which we removed either the wing's camber, corrugation, or both properties. Forces and aerodynamic power requirements during root flapping were derived from three-dimensional computational fluid dynamics modelling. Our data show that three-dimensional camber has no benefit for lift production and attenuates Rankine–Froude flight efficiency by up to approximately 12% compared to a flat wing. Moreover, we did not find evidence for lift-enhancing trapped vortices in corrugation valleys at Reynolds numbers between 137 and 1623. We found, however, that in all tested insect species, aerodynamic pressure distribution during flapping is closely aligned to the wing's venation pattern. Altogether, our study strongly supports the assumption that the wing's three-dimensional structure provides mechanical support against external forces rather than improving lift or saving energetic costs associated with active wing flapping.

description: An efficient management system and leadership body is one of the key requirements for a road safety improvement program. In low- and middle-income countries, the organizational structure of the management system may suffer from deficiencies weakening the institutional functions across key road safety players. Hence, it is necessary to form an inner- and inter-organization evaluation framework encompassing all the processes, events, dependencies, and causation among road safety players. In this paper, a (three-stage) system thinking approach is developed to evaluate the behavior of inter-organizational complex system and to determine major deficiencies in the role of the road safety lead agency. The first stages of the system thinking approach starts with drawing diagrams (i.e. multiple-effect and multiple-criteria trees) that allows identifying the chains of reasoning behind events or consequences. The next stage of the system thinking approach embodies the analytic network process (ANP), an advanced multi-criteria decision-making technique, which handles the lead agency capacity evaluation and helps to determine how and by what magnitude any of the players can affect the national road safety. The proposed method applies to the case of Iran, a middle-income developing country in the Middle East. Since in Iran, the Road Safety Commission (RSC) has been established as the lead agency, it was expected that RSC owns the greatest influence on the status of road safety. However, our results show that the overall influence of RSC on road safety is far less than what was expected. Subsequently, a supplementary procedure is proposed to specify institutional reforms in order to avoid such organizational inefficiencies.

description: XMM-Newton EPIC observations have revealed a bright point-like X-ray source in the nearby Magellanic-type galaxy NGC 55. At the distance of NGC 55, the maximum observed X-ray luminosity of the source, designated as XMMU J001528.9-391319, is L(x) ~ 1.6 x 10^{39} erg/s, placing the object in the ultraluminous X-ray source (ULX) regime. The X-ray lightcurve exhibits a variety of features including a significant upward drift over the 60 ks observation. Most notably a series of X-ray dips are apparent with individual dips lasting for typically 100-300 s. Some of these dips reach almost 100 percent diminution of the source flux in the 2.0-4.5 keV band. The EPIC CCD spectra can be modelled with two spectral components, a very soft powerlaw continuum (Gamma ~ 4) dominant below 2 keV, plus a multi-colour disc (MCD) component with an inner-disc temperature kT ~ 0.8 keV. The observed upperward drift in the X-ray flux can be attributed to an increase in the level of the MCD component, whilst the normalisation of the powerlaw continuum remains unchanged. The dipping episodes correspond to a loss of signal from both spectral components, although the blocking factor is at least a factor two higher for the MCD component. XMMU J001528.9-391319 can be considered as a candidate black-hole binary (BHB) system. A plausible explanation of the observed temporal and spectral behaviour is that we view the accretion disc close to edge-on and that, during dips, orbiting clumps of obscuring material enter our line of sight and cause significant blocking or scattering of the hard thermal X-rays emitted from the inner disc. In contrast, the more extended source of the soft powerlaw flux is only partially covered by the obscuring matter during the dips.

description: This research highlight presents findings on key features of rural off-farm work and incomes in Myanmar’s Dry Zone. It is based on analysis of data collected by the Rural Economy and Agriculture in Dry Zone (READZ) survey in 2017. READZ surveyed 1578 households in four townships: Budalin Township (Sagaing Region), Magway and Pwintbyu Townships (Magway Region), and Myittha Township (Mandalay Region). For this study, we define off-farm income as income originating from any work or activity that individuals perform away from their own household’s farm – thus it includes agricultural work for pay. We divide sources of off-farm income into two categories: “employment” and “self-employment”. Employment refers to any activity earning a wage or salary, and includes both temporary casual labor (“wage work”) and steady longer-term employment (“salaried work”). In contrast, “self-employment” refers to any off-farm activity that remunerates the individual in the form of profits from sales of goods or services. This includes all types of non-farm enterprise (including trade, retail, crafts, and services) as well as self-directed resource extraction activities (fishing, wood collection, etc.). Our results highlight the diversity of the off-farm economy in the Dry Zone and the growing reliance on off-farm income sources among rural households. We present our results in three parts. First we provide an overview of off-farm incomes in the Dry Zone. Second, we analyze the details of rural employment in greater detail. Third, we analyze patterns in self-employment.

description: We study a special running vacuum model (RVM) with $Λ= 3 αH^2+3βH_0^4 H^{-2}+Λ_0$, where $α$, $β$ and $Λ_0$ are the model parameters and $H$ is the Hubble one. This RVM has non-analytic background solutions for the energy densities of matter and radiation, which can only be evaluated numerically. From the analysis of the CMB power spectrum and baryon acoustic oscillation along with the prior of $α>0$ to avoid having a negative dark energy density, we find that $α<2.83\times 10^{-4}$ and $β=(-0.2^{+3.9}_{-4.5})\times 10^{-4}$ (95$\%$ C.L.). We show that the RVM fits the cosmological data comparably to the $Λ$CDM. In addition, we relate the fluctuation amplitude $σ_8$ to the neutrino mass sum $Σm_ν$.

description: This research highlight evaluates the extent of agricultural mechanization in four townships in Myanmar’s Dry Zone. It provides evidence that rapid mechanization is underway. Mechanical land preparation is now commonplace, due to thriving machine rental markets, falling equipment prices, and better financing options. The mechanization of harvesting and threshing is also occurring, but is concentrated in rice. These findings suggest that Dry Zone agriculture is at a technological crossroads. Data analyzed originates from the Rural Economy and Agriculture Dry Zone (READZ) survey, conducted in April and May 2017. The survey was designed to generate a detailed picture of the Dry Zone’s rural economy, including livelihoods, cropping systems, and farming practices. 1578 rural households were interviewed in the townships of Budalin, Myittha, Magway and Pwintbyu. These townships were selected purposively to ensure coverage of the major Dry Zone crops and farming systems. Enumeration areas and households were drawn at random using the sample frame of the national census, making the data statistically representative of rural areas of the four townships. Most results presented here are derived from an analysis of detailed plot- and crop-level data on machinery use

description: Myanmar is ranked second in the list of countries most affected by climate change (Kerft et al., 2014). Myanmar’s Central Dry Zone (CDZ) is subject to extremes of climate including high temperatures, droughts, floods and storms. The CDZ occupies more than two thirds of Myanmar’s agricultural land (JICA, 2013), and livelihoods there are highly dependent on agriculture, rendering them potentially vulnerable to a changing climate. With this in mind, a questionnaire was designed to capture data on climate change and its impacts on crop production in the CDZ, and to identify the adaptation measures being taken by communities. The survey was carried out in the three main regions of the CDZ; Magway, Sagaing and Mandalay. Group interviews were conducted with knowledgeable long-term residents of 300 villages in 14

description: This research highlight analyzes differences in productivity, profitability and labor use for four major crops produced in Myanmar’s Dry Zone, namely monsoon paddy, dry season paddy, sesame, and groundnut, comparing farmers using mechanized land preparation with those using draft animal power alone, and farmers using mechanized harvesting/threshing with those using manual and/or mixed methods. Analysis is based on data collected by the Rural Economy and Agriculture in the Dry Zone survey (READZ) from 1,578 rural households in four townships in Myanmar’s central Dry Zone in 2017 (see Belton et al., 2017). This research highlight summarizes the findings of Mather and Belton (2018).

description: Here we report on Landau level spectroscopy in magnetic fields up to 34 T performed on a thin film of topological insulator Bi$_2$Te$_3$ epitaxially grown on a BaF$_2$ substrate. The observed response is consistent with the picture of a direct-gap semiconductor in which charge carriers closely resemble massive Dirac particles. The fundamental band gap reaches $E_g=(175\pm 5)$~meV at low temperatures and it is not located on the trigonal axis, thus displaying either six or twelvefold valley degeneracy. Notably, our magneto-optical data do not indicate any band inversion. This suggests that the fundamental band gap is relatively distant from the $Γ$ point where profound inversion exists andgives rise to relativistic-like surface states of Bi$_2$Te$_3$.

description: The width of the giant dipole resonance (GDR) at finite temperature T in Sn-120 is calculated within the Phonon Damping Model including the neutron thermal pairing gap determined from the modified BCS theory. It is shown that the effect of thermal pairing causes a smaller GDR width at T below 2 MeV as compared to the one obtained neglecting pairing. This improves significantly the agreement between theory and experiment including the most recent data point at T = 1 MeV.

description: This research highlight presents key features of off-farm employment in Myanmar’s Southern Shan State. Analysis is based on the Shan Household Agriculture and Rural Economy Survey (SHARES), which collected detailed information on livelihoods and agriculture from 1562 households in nine townships. In this study, off-farm employment is defined as any income generating activity that does not take place on the household’s farm. Off-farm employment can therefore include both agriculture and non-agriculture related activities. We distinguish four main categories of off-farm employment: casual wage employment, salaried employment, non-farm enterprises, and natural resource extraction. Findings related to migration are presented in a separate research highlight. Below, we present the research findings in five sub-sections. The first provides a general overview of off-farm employment, and is followed by subsections presenting results on each of the four main categories of off-farm employment listed above.
