EFFICIENT AND EXPRESSIVE KEYWORD SEARCH OVER ENCRYPTED DATA IN CLOUD
Authors: Zeeshan Sharief
Published: April 2020

Searchable encryption allows a cloud server to conduct keyword search over encrypted data on behalf of the data users without learning the underlying plaintexts. However, most existing searchable encryption schemes only support single or conjunctive keyword search, while a few other schemes that can perform expressive keyword search are computationally inefficient since they are built from bilinear pairings over the composite-order groups. In this paper, we propose an expressive public-key searchable encryption scheme in the prime-order groups, which allows keyword search policies i.e., predicates, access structures to be expressed in conjunctive, disjunctive or any monotonic Boolean formulas and achieves significant performance improvement over existing schemes. We formally define its security and prove that it is selectively secure in the standard model. Also, we implement the proposed scheme using a rapid prototyping tool called Charm and conduct several experiments to evaluate it performance. The results demonstrate that our scheme is much more efficient than the ones built over the composite-order groups.

Fundamental trends within falling match rates: insights from the past decade of Canadian residency matching data
Authors: Zeng Andy , Brenna Connor , Ndoja Silvio
Published: April 2020

Background: The number of unmatched Canadian Medical Graduates (CMGs) has risen dramatically over the last decade. To identify long-term solutions to this problem, an understanding of the factors contributing to these rising unmatched rates is critical. 

Methods: Using match and electives data from 2009-2019, we employed machine learning algorithms to identify three clusters of disciplines with distinct trends in match and electives behaviours. We assessed the relationships between unmatched rates, competitiveness, rates of parallel planning, and program selection practices at a discipline level. 

Results: Across Canada, growth in CMGs has outpaced growth in residency seats, narrowing the seat-to-applicant ratio. Yet not all disciplines have been affected equally - a subset of surgical disciplines experienced a consistent decline in residency seats over time. Applicants to these disciplines are also at disproportionate risk of becoming unmatched, and this is associated with lower rates of parallel planning as quantified through clinical electives and match applications. This, in turn, is associated with the program selection practices of these disciplines. 

Conclusion: Long term solutions to the unmatched CMG crisis require more nuance than indiscriminately increasing residency seats and should consider cluster specific match ratios as well as regulations around clinical electives and program selection practices.

The Protest, Transformation of the Public Sphere and Notions of Femininity; Women Experiences in Pakistan
Authors: Ahmad Akhlaq , Yousaf Farhan Navid , Bilal Muhammad
Published: April 2020

This research analyzes women’s participation in a sit-in organized by a mainstream political party, Pakistan Awami Tehreek (PAT) in the capital territory of Pakistan. This sit-in continued for 86 days. Taking theoretical insights from Jurgen Habermas and Max Weber, this study looks at women’s experiences during the sit-in. The research discusses how the women transformed this ‘political sit-in’ into the public sphere and created alternative discursive space/s to looked into/evaluate their social, cultural, economic and political conditions and voiced their narratives into the present masculine/ patriarchal political structure of Pakistan. Interpretivist’ epistemology was a guiding methodological application for this research. The data come from 10 women participants. The thematic analysis helps the interpretation. Findings reveal that women exercised their agency as their religious duty, which in turn enabled them to develop their feminine social capital. Women transformed political sit-in into a distinct political space and challenged the traditional notions of Pakistani femininity. They lived in an open space for 86 days without their families, mostly taking decisions at their own, chanting anti-government slogans, having clashes with police, getting married and giving birth. Media facilitated projection, visibility and public support. Women’ commitment to the change disrupted dominant stereotypes about women, their role and voice in Pakistan. Charismatic leadership instrumentalized religious teachings for persuading participants and the advancement of the political agenda of socio-political change in Pakistan.

Authors: Sakanko Musa Abdullahi , Joseph David
Published: April 2020

Purpose of the study: The study aims is to examine the effect of trade openness on inflation rate in Nigeria.

Methodology: Time series data were collected from secondary sources.  EViews10 (statistical software for data analysis) ware employed to analyze the data collected.

Findings: The results revealed a cointegrating and one-way Granger causality between inflation rate, and trade openness. In addition, both the short-run and the long-run results demonstrate a significant and negative relationship between inflation rate and trade openness in Nigeria.

Application: The study is paramount to the government and policymakers in dealing and taking a decision regarding consumer price index and trade openness in Nigeria. We conclude that the government should work towards full diversification and diversion of the economy from oil export, control, and management of the degree of trade liberalization and the extent to which goods enter the country, and the control of money supplied.

Novelty/Originality: The study accorded to debate on the inflation rate, and trade openness in Nigeria looking, at both short-run and long-run effects, before few accessible studies focused on impact, and trade openness was not measured as the value of net export divided by gross domestic product. Finally, the paper contributed to the scanty of the literature.

Applicability of quartz grains surface analysis to the study of the genesis of unlithified sediments
Authors: Křížová Lenka , Křížek Marek , Lisá Lenka
Published: April 2020

This paper deals with genetic types of unlithified sediments and their characteristics with an emphasis on quartz grain surface microrelief. There are various physical-geographic agents in different sedimentary environments which play an important role in the origin of certain marks on the surface of sedimentary grains. As a result, studying the features of quartz grain surfaces enables us to determine the possible origin of sediments and landforms. Reference samples were chosen from geomorphological landforms of known origin: a moraine in the Labský Důl Valley, a debris flow in the Důl Bílého Labe Valley, a flood accumulation and deluvium from the Důl Bílého Labe Valley in the Krkonoše Mountains and eolian sediment from Klárov in Prague. Significant differences in surface micromorphology were found among these samples.

Published: April 2020

The article refers about the problems of Russian health care and higher and midlle medical education as integral elements of a single holistic system of the state in the conditions of their commercialization. A serious test for health care was the Covid-19 epidemic, which revealed the consequences of the so-called optimization of the medical industry: lack of an effective plan to prepare for the outbreak, lack of hospitals and beds, trained medical and nursing personnel, necessary equipment and medicines, test systems for determining coronavirus, protective suits, consumables, including masks. In order to understand modern trends, the dynamics of indicators of the state of the medical industry in Tsar 's Russia, the USSR and the Russian Federation after 1991 to the present have been traced. Modern Russia finds itself in a number of positions dropped to the indicators of 1913 (reduction of the number of hospitals and polyclinics, graduation of doctors and paramedics, in fact there is no medical industry, chemical and pharmaceutical production, etc.). The main elements of effective organization of higher medical education are identified, which presents both issues of material support of students and teachers, as well as core issues of educational process. The weaknesses of medical education have been identified, which are due both to the lack of sound State policy to support it and to its consequence - insufficient funding. The materials of the article make it possible to formulate the principles of restoration of domestic medical education as the foundation of the health care system.

THE NEXUS BETWEEN FISCAL DECENTRALIZATION AND GROSS INVESTMENT: A CASE STUDY OF PAKISTAN
Authors: Hamza Mr.
Published: April 2020

Many countries around the globe attempted to decentralize the powers either political or financial to perform more efficiently. Pakistan being in search of growth also attempted to decentralize the financial authorities into lower tiers. Researchers empirically tested the various propositions of fiscal decentralization and this study is an addition in the literature while exploring the fiscal decentralization and gross investment nexus in case of Pakistan. The data period for underlying hypothesis ranged from 1985 to 2015. This study measured fiscal decentralization through fiscal transfers and the other control variables are, inflation and trade openness. The selected model is estimated by employing Autoregressive Distributive Lag Model (ARDL). Fiscal transfers although has positive sign but statistically it is insignificant which suggest that theoretically it attract investment but statistically these impacts are insignificant. Allocation of delegated fund into irrelevant projects and the attitude of political leaders to delegate/devolve the financial powers are the probable reasons for these results. Inflation discourage investment in this study sample period and trade openness attract investment. In light of the findings of this study it is suggested that the government may allocate the fund properly, control inflation and open the borders for trade to attract investment in Pakistan.

DYNAMIC TRIP PLANNER FOR PUBLIC TRANSPORT USING GENETIC ALGORITHM
Authors: Basu Abhishek , Raja Bharathi , Gracious Rony , Vanajakshi Lelitha
Published: April 2020

This paper reports the development of a public transport trip planner to help the urban traveller in planning and
preparing for his commute using public transportation in the city. A Genetic Algorithm (GA) approach that handles real-time Global Positioning
Systems (GPS) data from buses of the Metropolitan Transport Corporation (MTC) in Chennai City (India) has been used to develop the planner.
The GA has been shown to provide good solutions within the problem’s computation time constraints. The developed trip planner has been
implemented for static network data first and subsequently extended to use real-time data. The “walk mode” and Chennai Mass Rapid Transit
System (MRTS) have also been included in the geospatial database to extend the route-planner’s capabilities. The algorithm has subsequently
been segmented to speed up the prediction process. In addition, a temporal cache has also been introduced during implementation, to handle

We report a new evaluation of the accretion properties of PDS 70b obtained with the Very Large Telescope/Multi Unit Spectroscopic Explorer. The main difference from the previous studies of Haffert et al. and Aoyama & Ikoma is in the mass accretion rate. Simultaneous multiple line observations, such as Hα and Hβ, can better constrain the physical properties of an accreting planet. While we clearly detected Hα emissions from PDS 70b, no Hβ emissions were detected. We estimate the line flux of Hβ with a 3σ upper limit to be 2.3 × 10−16 erg s−1 cm−2. The flux ratio F
Hβ
/F
Hα
for PDS 70b is <0.28. Numerical investigations by Aoyama et al. suggest that F
Hβ
/F
Hα
should be close to unity if the extinction is negligible. We attribute the reduction of the flux ratio to the extinction, and estimate the extinction of Hα (A
Hα
) for PDS 70b to be >2.0 mag using the interstellar extinction value. By combining with the Hα linewidth and the dereddening line luminosity of Hα, we derive the PDS 70b mass accretion rate to be ≳5 × 10−7 M
Jup yr−1. The PDS 70b mass accretion rate is an order of magnitude larger than that of PDS 70. We found that the filling factor f
f (the fractional area of the planetary surface emitting Hα) is ≳0.01, which is similar to the typical stellar value. The small value of f
f indicates that the Hα emitting areas are localized at the surface of PDS 70b.
Interferometric Closure Phase Uncertainties in the Low Signal-to-noise Ratio Regime
Authors: Christian Pierre , Psaltis Dimitrios
Published: April 2020

Closure phases are critical in astronomical interferometry. However, their uncertainties are difficult to compute numerically. We provide a method to efficiently compute interferometric closure phase distributions in terms of an approximate distribution that is valid in the low signal-to-noise ratio regime. This is done by first showing that the true phase distribution is well approximated by the von Mises distribution, then performing a convolution of three von Mises distributions. The resulting approximation superior to the normal distribution for all signal-to-noise ratios and, being fully analytic, allows for fast computations in statistical algorithms.
WIYN Open Cluster Study LXXIX. M48 (NGC 2548) I. Radial Velocities, Rotational Velocities, and Metallicities of Stars in the Open Cluster M48 (NGC 2548)*

Published: April 2020

WIYN/Hydra spectra (R ∼ 13,500, signal-to-noise pixel−1 = 50–1000) of a 400 Å region around Li 6708 Å are used to determine radial and rotational velocities for 287 photometrically selected candidate members of the open cluster M48. The sample ranges from turnoff A stars to late-K dwarfs and eight giants. We combine our V
RAD measurements and power spectrum analysis with parallax and proper motion data from Gaia DR2 to evaluate membership and multiplicity. We classify 152 stars as single cluster members, 11 as binary members, 16 as members of uncertain multiplicity, 56 as single nonmembers, 28 as single “likely” nonmembers, two as single “likely” members, one as a binary “likely” member, five as binary nonmembers, 10 as “likely” members of uncertain multiplicity, three as nonmembers of uncertain multiplicity, and three as “likely” nonmembers of uncertain multiplicity. From a subsample of 95 single members, we derive V
RAD = 8.512 ± 0.087 km s−1 (σ

μ
, and σ = 0.848 km s−1). Using 16 isolated Fe I lines for a subsample of 99 single members (that have

K (from 10 colors from UBVRI), v sin i < 25 km s−1, and well-behaved Fe I lines), [Fe/H]M48 = −0.063 ± 0.007 dex (σ

μ
). [Fe/H] is independent of T
eff over an unprecedentedly large range of 2500 K. The minimum cluster binary fraction is 11%–21%. M48 exhibits a clear but modest broadening of the main-sequence turnoff, and there is no correlation between color and v sin i.
Chandra Resolves the Double FU Orionis System RNO 1B/1C in X-Rays
Authors: Skinner Stephen L. , Güdel Manuel
Published: April 2020

We present new Chandra X-ray observations of the close pair of young stars RNO 1B and 1C (6″ separation) located in the L1287 cloud. RNO 1B erupted in 1978–1990 and is classified as an FU Orionis star (FUor). RNO 1C also shows most of the properties of an FUor but no eruption has been seen yet. Only a few dozen FUors are known and the presence of two such objects with a small angular separation is rare, suggesting a common origin. Both stars were faintly detected by Chandra and we summarize their X-ray properties within the framework of other previously detected FUors. We also report other X-ray detections in L1287 including the deeply embedded young star RNO 1G, the jet-like radio source VLA 3, and an enigmatic hard flaring source with no Two Micron All Sky Survey counterpart that was only detected in the second of the two Chandra exposures.
A Numerical Model for the Multiwavelength Lightcurves of PSR J0030+0451
Authors: Chen Alexander Y. , Yuan Yajie , Vasilopoulos Georgios
Published: April 2020

Recent modeling of Neutron Star Interior Composition Explorer (NICER) observations of the millisecond pulsar PSR J0030+0451 suggests that the magnetic field of the pulsar is non-dipolar. We construct a magnetic field configuration where foot points of the open field lines closely resemble the hotspot configuration from NICER observations. Using this magnetic field as input, we perform force-free simulations of the magnetosphere of PSR J0030+0451, showing the three-dimensional structure of its plasma-filled magnetosphere. Making simple and physically motivated assumptions about the emitting regions, we are able to construct the multiwavelength lightcurves that qualitatively agree with the corresponding observations. The agreement suggests that multipole magnetic structures are the key to modeling this type of pulsar, and can be used to constrain the magnetic inclination angle and the location of radio emission.

Magnetic perturbations characterize the solar wind interaction of the Moon. The solar wind plasma absorption on the dayside surface produces large-scale field perturbations behind, i.e., the field enhancement in the central wake and reduction on the wake boundary. The solar wind repellence over local lunar magnetic anomalies (LMAs) leads to small-scale magnetic compressions ahead. In this study, the magnetic perturbations around the Moon are examined by using the observations from a near-Moon satellite mission, the Lunar Prospector, and they exhibit a clear left–right asymmetry in a coordinate system related to the solar wind convection electric field (

). The magnetic field is observed to enhance before the left terminator that

points to, while on the opposite side, it is not. The test particle simulations show that

can divert the particles reflected over the LMAs to the left and then the solar wind pickup of these particles leads to the field enhancement observed before the left terminator. Behind the lunar terminator, the wake field reduction is also asymmetric. On the left, the field reduction is more remarkable and located closer to the central wake. The denser plasma, consisting of the background as well as the reflected solar wind particles, may produce a stronger diamagnetic current and thus more significant field reduction there. The asymmetric plasma and magnetic perturbations associated with the reflected particles may be a common and nonnegligible element during the solar wind interaction of a small-scale magnetic field, such as that of an asteroid or a comet.
A New Helioseismic Constraint on a Cosmic-time Variation of G

The best available estimate of 8640 days of low-ℓ
BiSON data is used to constrain the evolution of Newton’s constant over cosmic time. The effect of different chemical compositions and the impact of the theoretical uncertainties on the efficiency of the proton–proton (pp) fusion cross-section have been considered within a Bayesian approach. The resulting new helioseismic limit on the variation of the gravitational constant turns out to be

Le soft power de l’État sud-africain en action : le cas de la politique d’accès universel aux traitements antirétroviraux
Authors: Pelletan Charlotte
Published: April 2020

Cet article présente le marché public des antirétroviraux comme le lieu d’exercice du pouvoir d’influence de l’État sud-africain face aux producteurs de médicaments. Plus qu’un simple lieu d’achat des traitements antirétroviraux, le marché public constitue le cheval de Troie de l’État dans les activités des entreprises pharmaceutiques. Grâce à cette interface avec l’industrie pharmaceutique, le ministère de la Santé parvient à gagner du terrain sur le contrôle de la production au nom de la santé publique. L’Afrique du Sud est le pays du monde qui compte le plus grand nombre de personnes vivant avec le VIH ; il est également l’un des seuls pays africains dont l’industrialisation permet une réponse nationale spécifique. Ce texte rend ainsi compte des articulations – loin d’être harmonieuses – entre l’objectif de l’accès universel aux traitements du VIH/sida et les enjeux industriels et économiques du médicament en Afrique du Sud.
La mise à l’agenda du diabète au Mali : décalage et interdépendance entre acteurs locaux, nationaux et internationaux
Authors: Martini Jessica , Tijou-Traoré Annick , Mahieu Céline
Published: April 2020

Dans une perspective de sociologie de l’action publique, cet article interroge le rôle des acteurs locaux, nationaux et internationaux dans le processus de mise à l’agenda du diabète au Mali. À partir de l’histoire de la lutte contre cette maladie, il questionne les facteurs qui participent de sa lente progression dans l’agenda national, en dépit d’une mobilisation précoce des patients et des professionnels de santé. Il souligne ainsi l’impact de la perception dominante de la maladie ; de la capacité des acteurs locaux et nationaux à imposer des conceptions différentes en lien avec les ressources financières, cognitives et humaines à leur disposition ; de la manière dont la mobilisation associative est construite et de sa relation à l’État et au pouvoir médical ; du contexte économique, politique et sécuritaire. Ces facteurs nous ont permis de montrer à la fois le décalage et l’interdépendance entre les agendas locaux, nationaux et internationaux autour du diabète. Cette analyse permet d’éclairer une dynamique plus large, qui est celle de la lente progression de l’ensemble des maladies non transmissibles (MNT) parmi les priorités de la santé mondiale.
