description: The rationale of this study is to explain the link between household welfare, the region in which an infant is situated, literacy level of a mother and malaria prevalence among infants in Uganda with a more recent nationally representative data set that is the 2006 Uganda Demographic and Health Survey in lieu of the findings by other researchers on this particular subject. This was done with the aid of logit model estimation. The findings indicate that the region where an infant situated is fundamental in explaining malaria prevalence among infants. Alongside region is the location of a child whether he or she is in the rural or urban setting, the findings indicate that malaria prevalence lower among urban infants as compared to their rural counterparts. In conclusion, it was observed that malaria prevalence is not a case of household socioeconomic conditions but rather it's a communal disease as exemplified by the significance of region and urban-rural location of an infant.

description: This paper explores the debate on participatory approach by presenting evidence from the local communities practices living within the marine protected area in Tanzania (Mnazi Bay RuvumaEstuary Marine Park). Five out of fifteen villages that exist in Mnazi Bay Marine Park were selected for this study after consultation with the park authority. Stratified sampling of villages was conducted based on the location from the Indian Ocean: three villages located close to the sea (sea front villages) and two villages located far from the sea (inland villages). Both quantitative and qualitative data were collected using semi-structured questionnaires, focus group discussions, participant observation and interviews. The findings are presented using the local community narratives on livelihoods strategies and participation in decision-making processes to highlight the challenges of a participatory conservation approach in marine resources management within MPAs and also using regression analysis to explain the factors determining their participation. A Logit regression model is run. Results show that participatory approach in MPAs is a challenging phenomenon due to existence of multifaceted layers in marine resources management and use. These layers exist in terms of power struggle to manage resources and extract benefits associated with marine resources between state and local communities. This power struggle tends to undermine the ability of local communities to use and manage marine resources, threatening the attainment of the main objective of establishing the MPAs that’s improving the livelihood of the adjacent communities and improving the resources.
Intersecting hypersurfaces, topological densities and Lovelock Gravity

description: Intersecting hypersurfaces in classical Lovelock gravity are studied exploiting the description of the Lovelock Lagrangian as a sum of dimensionally continued Euler densities. We wish to present an interesting geometrical approach to the problem. The analysis allows us to deal most efficiently with the division of space-time into a honeycomb network of cells produced by an arbitrary arrangement of membranes of matter. We write the gravitational action as bulk terms plus integrals over each lower dimensional intersection. The spin connection is discontinuous at the shared boundaries of the cells, which are spaces of various dimensionalities. That means that at each intersection there are more than one spin connections. We introduce a multi-parameter family of connections which interpolate between the different connections at each intersection. The parameters live naturally on a simplex. We can then write the action including all the intersection terms in a simple way. The Lagrangian of Lovelock gravity is generalized so as to live on the simplices as well. Each intersection term of the action is then obtained as an integral over an appropriate simplex. Lovelock gravity and the associated topological (Euler) density are used as an example of a more general formulation. In this example one finds that singular sources up to a certain co-dimensionality naturally carry matter without introducing conical or other singularities in spacetime geometry.

description: This paper investigates organizational support for workers’ recuperation in Nigerian Banks. The study was conducted in Ilorin, the capital city of Kwara State, Nigeria. Eight commercial banks namely, United Bank for Africa, First Bank of Nigeria, Diamond Bank, Fidelity Bank, Wema Bank, First City Monument Bank and Union Bank were included in the study out of the seventeen commercial banks located in the city. Information was gathered through questionnaire administration that consisted of 128 respondents. The Chi square statistical tool was employed to test relationship between variables. Results showed that Nigerian Banks support their staff in recuperating during illness and help to maintain their as test of relationships were statistically significant. The P value of the hypotheses tested in the study are as follows; on the basis of medical facilities provided= 0.001; on adequacy of medical facilities =0.017 and other programmes provided = 0.002. The study suggested that government should enact a law that protects bank workers by ensuring that workers are excused from work as long as their illness lasted having been certified ill by recommended medical doctor.

description: The study employs cointegration, vector error correction model and Granger causality test to ascertain causation between financial development and economic performance in Tanzania. Economic performance is measured by the real GDP, whereas proxies for financial development are: the ratio of money supply to nominal GDP; and growth of credit to private sector. The results show that there is a stable long-run relationship between financial development and economic performance in Tanzania. Granger causality test indicates that the causality runs from financial development to economic performance.

description: The holographic description in the presence of gravitational Chern-Simons term is studied. The modified gravitational equations are integrated by using the Fefferman-Graham expansion and the holographic stress-energy tensor is identified. The stress-energy tensor has both conformal anomaly and gravitational or, if re-formulated in terms of the zweibein, Lorentz anomaly. We comment on the structure of anomalies in two dimensions and show that the two-dimensional stress-energy tensor can be reproduced by integrating the conformal and gravitational anomalies. We study the black hole entropy in theories with a gravitational Chern-Simons term and find that the usual Bekenstein-Hawking entropy is modified. For the BTZ black hole the modification is determined by area of the inner horizon. We show that the total entropy of the BTZ black hole is precisely reproduced in a boundary CFT calculation using the Cardy formula.

description: The JBPA private sector loan programme to Small Banana Farmers, jointly financed with the Jamaica Agricultural Development Foundation (JADF) provided practical lessons about the planning and operation of agricultural credit programmes. Success was linked to an independent extension service and rigid farmer selection criteria with extensive credit checks. Problems with land tenure needed creative solutions. All farmers were required to attend orientation meetings prior to signing loan documents. Loan disbursements were inputs rather than cash, with delivery at farmgate. Repayment was through point of sale deduction order, and sales were closely monitored to detect delinquents. Major problems were encountered with Hurricane Gilbert, and with farmer laxity when disbursements and transport of inputs ceased.
Obfuscating the Interconnects: Low-Cost and Resilient Full-Chip Layout Camouflaging

description: Layout camouflaging can protect the intellectual property of modern circuits. Most prior art, however, incurs excessive layout overheads and necessitates customization of active-device manufacturing processes, i.e., the front-end-of-line (FEOL). As a result, camouflaging has typically been applied selectively, which can ultimately undermine its resilience. Here, we propose a low-cost and generic scheme---full-chip camouflaging can be finally realized without reservations. Our scheme is based on obfuscating the interconnects, i.e., the back-end-of-line (BEOL), through design-time handling for real and dummy wires and vias. To that end, we implement custom, BEOL-centric obfuscation cells, and develop a CAD flow using industrial tools. Our scheme can be applied to any design and technology node without FEOL-level modifications. Considering its BEOL-centric nature, we advocate applying our scheme in conjunction with split manufacturing, to furthermore protect against untrusted fabs. We evaluate our scheme for various designs at the physical, DRC-clean layout level. Our scheme incurs a significantly lower cost than most of the prior art. Notably, for fully camouflaged layouts, we observe average power, performance, and area overheads of 24.96%, 19.06%, and 32.55%, respectively. We conduct a thorough security study addressing the threats (attacks) related to untrustworthy FEOL fabs (proximity attacks) and malicious end-users (SAT-based attacks). An empirical key finding is that only large-scale camouflaging schemes like ours are practically secure against powerful SAT-based attacks. Another key finding is that our scheme hinders both placement- and routing-centric proximity attacks; correct connections are reduced by 7.47X, and complexity is increased by 24.15X, respectively, for such attacks.

description: When Ismael Omar Guelleh became President of Djibouti in 1999, there were strong indications that the country was headed in a more democratic direction. Despite these indications, the period since has seen the Guelleh regime use heavy-handed tactics to repress dissent. Based on an examination of democratic contestation in the electoral arena, legislature, judiciary, media and civil society, this article argues that the regime is now fully authoritarian, yet draws little censure from the West. The US in particular has been willing to overlook the regime's democratic shortcomings due to the security-based geo-strategic importance attached to Djibouti, which hosts several foreign military bases. This case also points to a shift in the way the US engages with African regimes. While policy discourse continues to emphasize democratization, since 2001 Washington has become increasingly willing to overlook authoritarian drift and violations of human rights where security and counter- terrorist activities are concerned.

description: The issues of appropriate technology are discussed within the broad framework of agricultural development. Three leading Models concerned with the role of agriculture in economic development are reviewed to determine their relevance to the Caribbean. It is concluded that, aspects of all the models had varying degrees of relevance to the Caribbean but were not comprehensive enough for Caribbean realities. Despite dissatisfaction with the generalities of the Models we identified a fundamental role for appropriate technology in rural development. Perspectives relating to the appropriateness of Technology are discussed in the context of the receiving environment, the nature of the technology and the process by which the technology is generated. It was concluded that the circumstances of the large-farm sector were sufficiently different from that of the small-farm sector so that both the nature of the technology and the process of generation for each sector should be different. The farming systems approach is considered to provide the most useful insights for developing appropriate technology for specific target groups of farmers. The systems Framework is used to indicate the role of socio-economic analysis in developing appropriate technology.

description: A Bragg medium in the nonlinear Kerr regime, submitted to incident cw-radiation at a frequency in a band gap, switches from total reflection to transmission when the incident energy overcomes some threshold. We demonstrate that this is a result of nonlinear supratransmission, which allows to prove that i) the threshold incident amplitude is simply expressed in terms of the deviation from the Bragg resonance, ii) the process is not the result of a shift of the gap in the nonlinear dispersion relation, iii) the transmission does occur by means of gap soliton trains, as experimentally observed [D. Taverner et al., Opt Lett 23 (1998) 328], iv) the required energy tends to zero close to the band edge.

description: This paper is devoted to present new definition of complexity factor for static cylindrically symmetric matter configurations in $f(R,T,R_{μν}T^{μν})$ gravity. For this purpose, we have considered irrotational static cylindrical spacetime coupled with a locally anisotropic relativistic fluid. After formulating gravitational field and conservation equations, we have performed orthogonal splitting of the Riemann curvature tensor. Unlike GR (for spherical case) the one of the structure scalars $X_{TF}$, has been identified to be a complexity factor. This factor contains effective forms of the energy density, and anisotropic pressure components. Few peculiar relations among complexity factor, Tolman mass and Weyl scalar are also analyzed with the modified $f(R,T,R_{μν}T^{μν})$ corrections.

Molecular Targets of β-Lactam-Based Antimicrobials : Beyond the Usual Suspects
Creators: name: Konaklieva, Monika
Publisher: name: American University
Year: 2023

description: The common practice in antibacterial drug development has been to rapidly make an attempt to find ever-more stable and broad-spectrum variants for a particular antibiotic, once a drug resistance for that antibiotic is detected. We are now facing bacterial resistance toward our clinically relevant antibiotics of such a magnitude that the conversation for antimicrobial drug development ought to include effective new antibiotics with alternative mechanisms of action. The electrophilic β-lactam ring is amenable for the inhibition of different enzyme classes by a suitable decoration of the core scaffold. Monocyclic β-lactams lacking an ionizable group at the lactam nitrogen exhibit target preferences toward bacterial enzymes important for resistance and virulence. The present review intends to draw attention to the versatility of the β-lactams as antimicrobials with ―unusual‖ molecular targets.

In the present paper we will show that any matrix can be expanded in terms of the matrix configuration representing NC4S just like any matrix can be expanded into symmetrized products of the matrix configuration for non-commutative S^2. Then a scalar field theory on NC4S is constructed. Our matrix configuration describes two S^4's joined at the circle and the Matrix theory action contains a projection matrix inside the trace to restrict the space of matrices to that for one S^4.

Extensive investigations, including laboratory x-ray and synchrotron radiation diffraction, 13C NMR, MAS and Raman spectroscopy, show a monoclinic I2/m structure, characterized by chains of [2+2]-cycloaddicted fullerenes, sideways connected by single C-C bonds. This leads to the formation of polymeric layers, whose insulating nature, deduced from the NMR and Raman spectra, denotes the complete localization of the electrons involved in the covalent bonds.

description: In this paper, we investigate the tensor form factors of $P\to P,\,S,\,V$ and $A$ transitions within the standard light-front (SLF) and the covariant light-front (CLF) quark models (QMs). The self-consistency and Lorentz covariance of CLF QM are analyzed via these quantities, and the effects of zero-mode are discussed. For the $P\to V$ and $A$ transitions, besides the inconsistence between the results extracted via longitudinal and transverse polarization states, which is caused by the residual $ω$-dependent spurious contributions, we find and analyze a "new" self-consistence problem of the traditional CLF QM, which is caused by the different strategies for dealing deal with the trace term in CLF matrix element. A possible solution to the problems of traditional CLF QM is discussed and confirmed numerically. Finally, the theoretical predictions for the tensor form factors of some $c\to q,\,s$ and $b\to q,\,s\,,c$ ($q=u,d$) induced $P\to P,\,S,\,V$ and $A$ transitions are updated within the CLF QM with a self-consistent scheme.

description: We have studied the roughness of a contact line of a liquid meniscus on a disordered substrate by measuring its width distribution. The comparison between the measured width distribution and the width distribution calculated in previous works, extended here to the case of open boundary conditions, confirms that the Joanny-de Gennes model is not sufficient to describe the dynamics of contact lines at the depinning threshold. This conclusion is in agreement with recent measurements which determine the roughness exponent by extrapolation to large system sizes.

description: We give a simple interpretation of the recent solutions for cosmologies with a transient accelerating phase obtained from compactification in hyperbolic manifolds, or from S-brane solutions of string/M-theory. In the four-dimensional picture, these solutions correspond to bouncing the radion field off its exponential potential. Acceleration occurs at the turning point, when the radion stops and the potential energy momentarily dominates. The virtues and limitations of these approaches become quite transparent in this interpretation.

description: We present observations of the most bright main sequence stars in the Small Magellanic Cloud stellar cluster NGC330 obtained with the integral field spectrograph MUSE@VLT. The use of this valuable instrument allows us to study both photometric and spectroscopic properties of stellar populations of this young star cluster. The photometric data provide us a precise color magnitude diagram, which seems to support the presence of two stellar populations of ages of $\sim$ 18 Myr and $\sim$ 30 Myr assuming a metallicity of Z = 0.002. Thanks to the spectroscopic data, we derive helium abundance of 10 main sequence stars within the effective radius Reff= 20" of NGC330, thus leading to an estimation of $ε(He)$ = 10.93 $\pm$ 0.05 (1$σ$ ). The helium elemental abundances of stars likely belonging to the two possible stellar populations, do not show differences or dichotomy within the uncertainties. Thus, our results suggest that the two stellar populations of NGC330, if they exist, share similar original He abundances. If we consider stellar rotation velocity in our analysis, a coeval (30 Myr) stellar population, experiencing different values of rotation, cannot be excluded. In this case, the mean helium abundance < $ε(He)$ >rot obtained in our analysis is 11.00 $\pm$ 0.05 dex. We also verified that possible NLTE effects cannot be identified with our analysis because of the spectral resolution and they are within our derived abundance He uncertainties. Moreover, the analysis of the He abundance as a function of the distance from the cluster center of the observed stars do not show any correlation.

description: Results obtained from an X-ray spectral survey of nearby Seyfert galaxies using XMM--Newton are reported. The sample was optically selected, well defined, complete in B mag, and distance limited: it consists of the nearest (D<22 Mpc) 27 Seyfert galaxies (9 of type 1, 18 of type 2) taken from the Ho et al. (1997) sample. This is one of the largest atlases of hard X-ray spectra of low-L active galaxies ever assembled. All nuclear sources except two Sey 2s are detected between 2-10 keV, half for the first time ever, and average spectra are obtained for all of them. Nuclear luminosities reach values down to 10**38 erg/s. The shape of the distribution of X-ray parameters is affected by the presence of Compton-thick objects (> 30% among type 2s). The latter have been identified either directly from their intense FeK line and flat X-ray spectra, or indirectly with flux diagnostic diagrams which use isotropic indicators. After taking into account these highly absorbed sources, we find that (i) the intrinsic X-ray spectral properties (i.e., spectral shapes and luminosities above 2 keV) are consistent between type 1 and type 2 Sey, as expected from ``unified models'', (ii) Sey galaxies as a whole are distributed fairly continuously over the entire range of Nh, between 10**20 and 10**25 cm**-2, and (iii) while Sey 1s tend to have lower Nh and Sey 2s tend to have the highest, we find 30% and 10% exceptions, respectively. Overall the sample well represents the average intrinsic X-ray spectral properties of nearby AGN, including a proper estimate of the distribution of their absorbing columns. Finally, we conclude that, with the exception of a few cases, the present study agrees with predictions of unified models of Sey galaxies, and extends their validity down to very low luminosities.

description: Starting from Rodrigues formula we present a general construction of raising and lowering operators for orthogonal polynomials of continuous and discrete variable on uniform lattice. In order to have these operators mutually adjoint we introduce orthonormal functions with respect to the scalar product of unit weight. Using the Infeld-Hull factorization method, we generate from the raising and lowering operators the second order self-adjoint differential/difference operator of hypergeometric type.

description: 111ncreasing international trade in agricultural products often must be accompanied by strengthening import regulations designed to prevent the introduction of exotic livestock diseases or plant pests, which could devastate agricultural production in the importing country. Stricter regulations may separate world markets into so-called "free" and "affected" markets or may redefine their boundaries. Foot-and-mouth disease (FMD) and regulations regarding it are a prime example. FMD is a serious, contagious viral disease that primarily affects cattle, swine, and other cloven-hoofed animals. Because of the nature and severity of the disease (see box), FMD is a major determinant of world beef trade patterns.
Completely Positive Post-Markovian Master Equation via a Measurement Approach

description: A new post-Markovian quantum master equation is derived, that includes bath memory effects via a phenomenologically introduced memory kernel k(t). The derivation uses as a formal tool a probabilistic single-shot bath-measurement process performed during the coupled system-bath evolution. The resulting analytically solvable master equation interpolates between the exact Nakajima-Zwanzig equation and the Markovian Lindblad equation. A necessary and sufficient condition for complete positivity in terms of properties of k(t) is presented, in addition to a prescription for the experimental determination of k(t). The formalism is illustrated with examples.

description: The formation and evolution of galaxies is highly dependent on the dynamics of stars and gas, which is governed by the underlying law of gravity. To investigate how the formation and evolution of galaxies takes place in Milgromian gravity (MOND), we present full hydrodynamical simulations with the Phantom of Ramses (POR) code. These are the first-ever galaxy formation simulations done in MOND with detailed hydrodynamics, including star formation, stellar feedback, radiative transfer and supernovae. These models start from simplified initial conditions, in the form of isolated, rotating gas spheres in the early Universe. These collapse and form late-type galaxies obeying several scaling relations, which was not a priori expected. The formed galaxies have a compact bulge and a disk with exponentially decreasing surface mass density profiles and scale lengths consistent with observed galaxies, and vertical stellar mass distributions with distinct exponential profiles (thin and thick disk). This work thus shows for the first time that disk galaxies with exponential profiles in both gas and stars are a generic outcome of collapsing gas clouds in MOND. These models have a slight lack of stellar angular momentum because of their somewhat compact stellar bulge, which is connected to the simple initial conditions and the negligible later gas accretion. We also analyse how the addition of more complex baryonic physics changes the main resulting properties of the models and find this to be negligibly so in the Milgromian framework.

description: Up nlike many other developed counties, the United States enjoys a competitive advantage in world agricultural trade. Abundant natural resources and modern technology have helped make the United States a net exporter of agricultural products. Competitive advantages in agricultural trade are particularly strong for U.S. grains and oilseeds. These findings are based on comparisons of an economic statistic called "relative trade advantage," or RTA. The RTA identifies a country's competitive advantage or competitive disadvantage for an individual commodity or for an industry as a whole (see box). Based on international trade data, the RTA measures the ability of domestic producers of a specified commodity to compete against other commodities for national resources. It also shows how well the country competes in international markets for the specified commodity. RTA's are generally positive when exports exceed imports. Since no country exports without also importing, each country will have commodities with positive and negative RTA's.

description: In the present paper we propose a stellar model under the $f(\mathbb{T})$ gravity following the conjecture of Mazur-Mottola~[Report number: LA-UR-01-5067 (2001); Proc. Natl. Acad. Sci. USA 101 (2004) 9545] known in literature as {\it gravastar}, a viable alternative to the black hole. This gravastar has three different regions, viz., (A) Interior core region, (B) Intermediate thin shell, and (C) Exterior spherical region. It is assumed that in the interior region the fluid pressure is equal to a negative matter-energy density providing a constant repulsive force over the spherical thin shell. This shell at the intermediate region is assumed to be formed by a fluid of ultrarelativistic plasma and the pressure, which is directly proportional to the matter-energy density according to Zeldovich's conjecture of stiff fluid~[Zeldovich, Mon. Not. R. Astron. Soc. 160 (1972) 1], does nullify the repulsive force exerted by the interior core region for a stable configuration. On the other hand, the exterior spherical region can be described by the exterior Schwarzschild-de Sitter solution. With all these specifications we have found out a set of exact and singularity-free solutions of the gravastar which presents several physically interesting as well as valid features within the framework of alternative gravity.
