description: Multicomponent quantum Hall systems with internal degrees of freedom provide a fertile ground for the emergence of exotic quantum liquids. Here we investigate the possibility of non-Abelian topological order in the half-filled fractional quantum Hall (FQH) bilayer system driven by the tunneling effect between two layers. By means of the state-of-the-art density-matrix renormalization group, we unveil "finger print" evidence of the non-Abelian Moore-Read Pfaffian state emerging in the intermediate-tunneling regime, including the ground-state degeneracy on the torus geometry and the topological entanglement spectroscopy (entanglement spectrum and topological entanglement entropy) on the spherical geometry, respectively. Remarkably, the phase transition from the previously identified Abelian $(331)$ Halperin state to the non-Abelian Moore-Read Pfaffian state is determined to be continuous, which is signaled by the continuous evolution of the universal part of the entanglement spectrum, and discontinuities in the excitation gap and the derivative of the ground-state energy. Our results not only provide a "proof-of-principle" demonstration of realizing a non-Abelian state through coupling different degrees of freedom, but also open up a possibility in FQH bilayer systems for detecting different chiral $p-$wave pairing states.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: This study attempts to analyze the impact of per capita income, mother education, per capita public health expenditure, access to health facilities, clean water and sanitation on prevalence of child stunting in Ethiopia. For this purpose, regional state panel data is used to estimate a reduced form of health production using fixed effect model estimation technique. The results show per capita income, per capita public health expenditure, access to clean water and mothers' education significantly affect prevalence of child stunting. However, mother education becomes insignificant when the impact of access to clean water source, sanitation facilities and healthcare services are controlled. On the other hand, population per physician (proxy for access to health care services) and access to sanitation facilities have insignificant impact. The results suggest important role of income growth policies and promoting mother education to reduces prevalence of child stunting.

description: In this work we investigate localized and extended objects for gravitating, self-interacting phantom fields. The phantom fields come from two scalar fields with a "wrong sign" (negative) kinetic energy term in the Lagrangian. This study covers several solutions supported by these phantom fields: phantom balls, traversable wormholes, phantom cosmic strings, and "phantom" domain walls. These four systems are solved numerically and we try to draw out general, interesting features in each case.

description: Antibiotic resistance is a global concern. Two members of the bacterial genus Elizabethkingia, namely, E. anophelis and E. meningoseptica have raised much concern in recent years because of their resistance to multiple commonly used antibiotics. Identification of multidrug resistant and pan-drug resistant bacteria has propelled the search for new antibiotics that can act on unconventional targets. Researches are going on to find out the possibility of using bacterial ribonucleotide reductases as a novel target for antibiotic development. Through in silico evaluations, this study aims for characterization and functional annotation of ribonucleotide reductase enzymes of E. anophelis and E. meningoseptica. Binding affinities with these enzymes of the compounds that have shown promising results in inhibiting Pseudomonas aeruginosa growth by acting on its ribonucleotide reductase were also assessed by molecular docking and dynamics simulations. Insights from this study will help in battling these infections in the near future. Communicated by Ramaswamy H. Sarma

description: Memory effects play a fundamental role in the study of the dynamics of open quantum systems. There exist two conceptually distinct notions of memory discussed for quantum channels in the literature. In quantum information theory quantum channels with memory are characterised by the existence of correlations between successive applications of the channel on a sequence of quantum systems. In open quantum systems theory memory effects arise dynamically during the time evolution of quantum systems, and define non-Markovian dynamics. Here we relate and combine these two different concepts of memory. In particular, we study the interplay between correlations between multiple uses of quantum channels and non-Markovianity as non-divisibility of the $t$-parametrized family of channels defining the dynamical map.

The Relationship Between Unemployment and Economic Growth in Sub–Sahara African Countries: A Panel Vector Auto regression Approach
Creators: name: Osman, Muhammed
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This study examines the relationship between unemployment and economic growth using panel data for a panel of Sub-Sahara African countries for the period 1991-2014. The PMG regression technique result indicates that negative long run relationship between unemployment and economic growth. Both FDI and population growth stimulate economic growth in the region. However, the short-run association between economic growth and these variables are weak. Results from DOLS and FMOLS estimates indicate that there is negative relationship between unemployment and economic growth in the long run. The variance decomposition result shows that the effect of economic growth to reduce unemployment is minimal. Based on these findings, the study recommends that the policy makers of these countries must recognize the effect of economic growth in reducing unemployment and also using the growing population as an input for the economic growth of the region by designing appropriate education system.
The effect of real exchange rate on the trade balance of Ethiopia: does MARSHALL LERNER condition holds? Evidence from (VECM) analysis
Creators: name: Debela, Gelana
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This paper attempts to investigate the empirical investigation of the effect of real exchange rate on the trade balance of Ethiopia and whether the Marshall Lerner condition holds using vector error correction (VECM) co-integration method using quarterly data from 1995Q1 to 2017Q4. To make appropriate analysis, the study has used the Granger causality test, impulse response function and variance decomposition method in the short run whilst the vector error correction model (VECM) has undertaken to estimate the long run causality whether real exchange rate improves or worsen trade balance. The study included other control variables like domestic and foreign income and real money supply in addition to real exchange rate. The empirical results thus, indicated a long run significant relationship between trade balance and its determinants; real exchange rate, domestic income, foreign income, and real money supply as incorporated in the model specification of the study. The result of the impulse response function as well indicated that there is no evidence of J-curve in Ethiopia. The study concludes with important implications for policymakers because it provides evidence supporting the fact that the real exchange rate has a major impact on trade balance adjustment and that devaluation of real effective exchange rate worsens the trade balance of Ethiopia even in the long run.

description: The swimming of a two-sphere system and of a three-sphere chain in an incompressible viscous fluid is studied on the basis of simplified equations of motion which take account of both Stokes friction and added mass effects. The analysis is based on an explicit expression for the asymptotic periodic swimming velocity and a corresponding evaluation of the mean rate of dissipation. The mean swimming velocity of the two-sphere system is found to be non-vanishing provided that the two spheres are not identical. The swimming of a comparable chain of three identical spheres is much more efficient.

description: SARS-COV-2 is responsible for the COVID-19 pandemic, which has infected more than 767 million people worldwide including about 7 million deaths till 5 June 2023. Despite the emergency use of certain vaccines, deaths due to COVID-19 have not yet stopped completed. Therefore, it is imperative to design and develop drugs that can be used to treat patients suffering from COVID-19. Here, two peptide inhibitors derived from nsp7 and nsp8 cofactors of nsp12 have been shown to block different substrate binding sites of nsp12 that are mainly responsible for the replication of the viral genome of SARS-CoV-2. By using the docking, molecular dynamics (MD), and MM/GBSA techniques, it is shown that these inhibitors can bind to multiple binding sites of nsp12, such as the interface of nsp7 and nsp12, interface of nsp8 and nsp12, RNA primer entry site, and nucleoside triphosphate (NTP) entry site. The relative binding free energies of the most stable protein-peptide complexes are found to lie between ∼−34.20 ± 10.07 to −59.54 ± 9.96 kcal/mol. Hence, it is likely that these inhibitors may bind to different sites of nsp12 to block the access of its cofactors and the viral genome, thereby affecting the replication. It is thus proposed that these peptide inhibitors may be further developed as potential drug candidates to suppress the viral loads in COVID-19 patients. Communicated by Ramaswamy H. Sarma
Evaluating the Impact of Trade Preference Scheme on Ethiopian Export Gravity Model Approach

Publisher: name: National Academic Digital Repository of Ethiopia

description: To integrate least developed countries including Ethiopia in to international trade market, African Growth Opportunity (AGOA) and Everything But Arm (EBA) initiatives have been designed by U.S. and European countries respectively. The purpose of these initiatives is to enhance and diversify the export of the beneficiary countries. Therefore the purpose of this study is to analyze the effects of these programs on Ethiopian export. The study employs the fixed effect gravity model using panel data for the period 1974/75 -2005/06 of annual data. The main findings of the study show that AGOA has negative contribution to Ethiopian Export. This might be explained from both beneficiary (i.e. Ethiopia) and granting country's limitation. Poor infrastructure, lack of skilled manpower, poor public services, etc of Ethiopia is some of the limitation to exploit the scheme. Whereas un stability of the program, rules of origin, non tariff barriers are some of the factors that hinders the exploitation of the scheme. The result of the study also indicates that the European Union initiative has no significant effect on Ethiopian export. Like U.S. initiative this program has also its own limitations, but still Ethiopia has to identify the drawbacks in exploiting the program. The policy implication of the finding is that to exploit the program Ethiopia has to solve the drawbacks for her poor export performance. Especially she has to use export diversification strategy, i.e. the government has to peruse to diversify exportable commodities from agriculture to other products both vertically and horizontally in order to be competitive. Since most of export items relied on few primary products. In addition to this the government has to give due attention to improve social capital, skilled manpower, public services infrastructure etc. Key words: AGOA,EBA,EXPORT

description: We summarize a laser-ranged satellite test of frame-dragging, a prediction of General Relativity, and then concentrate on the estimate of thermal thrust, an important perturbation affecting the accuracy of the test. The frame dragging study analysed 3.5 years of data from the LARES satellite and a longer period of time for the two LAGEOS satellites. Using the gravity field GGM05S obtained via the Grace mission, which measures the Earth's gravitational field, the prediction of General Relativity is confirmed with a 1-$σ$ formal error of 0.002, and a systematic error of 0.05. The result for the value of the frame dragging around the Earth is $μ$ = 0.994, compared to $μ$ = 1 predicted by General Relativity. The thermal force model assumes heat flow from the sun (visual) and from Earth (IR) to the satellite core and to the fused silica reflectors on the satellite, and reradiation into space. For a roughly current epoch (days 1460 - 1580 after launch) we calculate an average along-track drag of -0.50 $pm/s^{2}$.

description: The main-protease (Mpro) catalyzes a crucial step for the SARS-CoV-2 life cycle. The recent SARS-CoV-2 presents the main protease (MCoV2pro) with 12 mutations compared to SARS-CoV (MCoV1pro). Recent studies point out that these subtle differences lead to mobility variances at the active site loops with functional implications. We use metadynamics simulations and a sort of computational analysis to probe the dynamic, pharmacophoric and catalytic environment differences between the monomers of both enzymes. So, we verify how much intrinsic distinctions are preserved in the functional dimer of MCoV2pro, as well as its implications for ligand accessibility and optimized drug screening. We find a significantly higher accessibility to open binding conformers in the MCoV2pro monomer compared to MCoV1pro. A higher hydration propensity for the MCoV2pro S2 loop with the A46S substitution seems to exercise a key role. Quantum calculations suggest that the wider conformations for MCoV2pro are less catalytically active in the monomer. However, the statistics for contacts involving the N-finger suggest higher maintenance of this activity at the dimer. Docking analyses suggest that the ability to vary the active site width can be important to improve the access of the ligand to the active site in different ways. So, we carry out a multiconformational virtual screening with different ligand bases. The results point to the importance of taking into account the protein conformational multiplicity for new promissors anti MCoV2pro ligands. We hope these results will be useful in prospecting, repurposing and/or designing new anti SARS-CoV-2 drugs. Communicated by Ramaswamy H. Sarma

description: Hydrodynamical interaction of spherical ejecta freely expanding at mildly relativistic speeds into an ambient cold medium is studied in semi-analytical and numerical ways to investigate how ejecta produced in energetic stellar explosions dissipate their kinetic energy through the interaction with the surrounding medium. We especially focus on the case in which the circumstellar medium is well represented by a steady wind at a constant mass-loss rate having been ejected from the stellar surface prior to the explosion. As a result of the hydrodynamical interaction, the ejecta and circumstellar medium are swept by the reverse and forward shocks, leading to the formation of a geometrically thin shell. We present a semi-analytical model describing the dynamical evolution of the shell and compare the results with numerical simulations. The shell can give rise to bright emission as it gradually becomes transparent to photons. while it is optically thick. We develop an emission model for the expected emission from the optically thick shell, in which photons in the shell gradually diffuse out to the interstellar space. Then, we investigate the possibility that radiation powered by the hydrodynamical interaction is the origin of an underluminous class of gamma-ray bursts.

description: We combine the decade long photometry of the Be/X-ray binary system A0538-66 provided by the MACHO and OGLE IV projects with high resolution SALT spectroscopy to provide detailed constraints on the orbital parameters and system properties. The ~420d superorbital modulation is present throughout, but has reduced in amplitude in recent years. The well-defined 16.6409d orbital outbursts, which were a strong function of superorbital phase in the MACHO data (not occurring at all at superorbital maximum), are present throughout the OGLE IV coverage. However, their amplitude reduces during superorbital maximum. We have refined the orbital period and ephemeris of the optical outburst based on ~25 yrs light curves to HJD = 2455674.48 +/- 0.03 + n*16.6409 +/- 0.0003d. Our SALT spectra reveal a B1 III star with vsini of 285 km/s from which we have derived an orbital radial velocity curve which confirms the high eccentricity of e = 0.72 +/- 0.14. Furthermore, the mass function indicates that, unless the neutron star far exceeds the canonical 1.44 Msun, the donor must be significantly undermassive for its spectral type. We discuss the implications of the geometry and our derived orbital solution on the observed behaviour of the system.

R-mode frequencies of rapidly and differentially rotating relativistic neutron stars

description: R-modes of neutron stars could be a source of gravitational waves for ground based detectors. If the precise frequency $σ$ is known, guided gravitational wave searches with enhanced detectability are possible. Because of its physical importance many authors have calculated the r-mode frequency. For the dominant mode, the associated gravitational wave frequency is 4/3 times the angular velocity of the star $Ω$, subject to various corrections of which relativistic and rotational corrections are the most important. This has led several authors to investigate the dependence of the r-mode frequency on factors such as the relativistic compactness parameter ($M/R$) and the angular velocity of stars with different equations of state. The results found so far, however, are almost independent of the equation of state. Here we investigate the effect of rapid rotation and differential rotation on $σ$. We evolve the perturbation equations using the Cowling approximation by applying finite differencing methods to compute the r-mode frequency for a series of rotating neutron stars with polytropic equations of state. We find that rotational effects in the r-mode frequency can be larger than relativistic effects for rapidly spinning stars with low compactness, reducing the observed frequency. Differential rotation also acts to decrease $σ$, but its effect inscreases with the compactness. The results presented here are relevant to the design of gravitational wave and electromagnetic r-mode searches.

The effect of energy consumption and economic growth on carbon dioxide emissions in 14 selected African countries: Evidence from panel-ARDL
Creators: name: Demisse, Jarsa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The study analyzed the effect of economic growth, energy consumption, population density and urbanization on carbon dioxide emission in 14 selected East African countries, with the main interest of the effect of energy consumption and economic growth over the period 1980 to 2016, except for Ethiopia (1981-2016), Tanzania (1988-2016) and Uganda (1982-2016). In doing this, the study used Panel-Autoregressive Distributive Lag (Panel-ARDL), model. Result of panel unit root tests revealed the model variables have a mixed order of integration (or I (0) and I (1)) and none of them I (2). Result of co-integration tests confirmed the existence of long-run co-integrating relationship among the model variables. Pooled mean group estimation result shows all the model explanatory variables were statistically significant in the long-run to explain the variance of carbon dioxide emission for the analyzed countries. The result shows energy consumption, growth in output, population density and urbanization leads to an increase in emission of the gas in the long-run. Energy consumption and economic growth also found significant and have a positive impact in the short-run too, while urbanization found significant and have a negative impact yet it is in a statistical sense. The population density was found insignificant in the short-run. Hence, the study recommended the governments and policymakers in the analyzed countries to develop and implement long-term energy, economic and demographic policies such as switching to cleaner energy alternatives like wind, hydro, biogas, biofuels and solar, green investment in the field of green technologies in order to lower the opportunities of future carbonization of the economic structure, and controlling the rate of population via intervention mechanism like women empowerment, improving girl education as well as creating awareness on negative effect of having a large family size.

description: Superconductivity within layered crystal structures has attracted sustained interest among condensed matter community, primarily due to their exotic superconducting properties. EuBiS2F is a newly discovered member in the BiS2-based superconducting family, which shows superconductivity at 0.3 K without extrinsic doping. With 50 at.% Ce substitution for Eu, superconductivity is enhanced with Tc increased up to 2.2 K. However, the mechanisms for the Tc enhancement have not yet been elucidated. In this study, the Ce-doping effect on the self-electron-doped superconductor EuBiS2F was investigated by X-ray absorption spectroscopy (XAS). We have established a relationship between Ce-doping and the Tc enhancement in terms of Eu valence changes and nanoscale atomic displacements. The new finding sheds light on the interplay among superconductivity, charge and local structure in BiS2-based superconductors.

description: The COVID-19 pandemic has severely destructed human life worldwide, with no suitable treatment until now. SARS-CoV-2 virus is unprecedented, resistance against number of therapeutics and spreading rapidly with high mortality, which warrants the need to discover new effective drugs to combat this situation. This current study is undertaken to explore the antiviral potential of marine algal compounds to inhibit the viral entry and its multiplication using computational analysis. Among the proven drug discovery targets of SARS-CoV-2, spike glycoprotein and 3-chymotrypsin-like protease are responsible for the virus attachment and viral genome replication in the host cell. In this study, the above-mentioned drug targets were docked with marine algal compounds (sulfated polysaccharides, polysaccharide derivatives and polyphenols) using molecular docking tools (AutoDockTools). The obtained results indicate that κ-carrageenan, laminarin, eckol, trifucol and β-D-galactose are the top-ranking compounds showing better docking scores with SARS-CoV-2 targets, than the current experimental COVID-19 antiviral drugs like dexamethasone, remdesivir, favipiravir and MIV-150. Further, molecular dynamic simulation, ADMET and density functional theory calculations were evaluated to substantiate the findings. To the best of our knowledge, this is the first report on in silico analysis of aforesaid algal metabolites against SARS-CoV-2 targets. This study concludes that these metabolites can be curative for COVID-19 in the hour of need after further validations in in vitro and in vivo testings. Communicated by Ramaswamy H. Sarma

At lower density, the Landau levels are mainly dominated by u and d quarks. Threshold values of the chemical potential for the s quark onset are shown in the $μ$-$B$ plane. The magnetic-field-dependent running coupling can broaden the region of three-flavor matter by decreasing the dynamical masses of $s$ quarks. Before the onset of $s$ quarks, the Landau level number of light quarks is directly dependent on the magnetic field strength $B$ by a simple inverse proportional relation $k_{i,\mathrm{max}}\approx B_i^0/B$ with $B_d^0=5\times 10^{19}$ G, which is approximately 2 times $B_u^0$ of $u$ quarks at a common chemical potential. When the magnetic field increases up to $B^0_d$, almost all three flavors are lying in the lowest Landau level.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Conjoint analysis was applied to asses the part worth of beef quality and safety attributes using a cross sectional data from a stratified sample of 300 households in Addis Ababa city collected in June 2007. The software used for estimation is SPSS 15. Results show that fat content, freshness, neatness of meat shop and personnel, abattoir stamp and price are significant quality and safety attributes that consumers use in their beef purchase decisions. Interactive variables like family size, religion, age, schooling, stay in Addis Ababa and martial status are also found to significantly influence quality and safety perceptions. On the other hand some variables such as sex of meal planners are found to have insignificant role in quality and safety perception. The result further indicates that income has a great role in influencing people perception regarding safety and quality of beef. The result of the study could be used for designing safety and quality standard for local wet market. Key words: Beef demand, Quality and safety attributes, conjoint analysis, Addis Ababa

description: Fanconi anaemia pathway repairs inter-strand cross linking damage (ICL) of the DNA. Monoubiquitination of FANCD2 and FANCI is very crucial for ICL repairing. In this work we have tried to understand the monoubiquitinated FANCD2 structure, which facilitates the FANCD2 for binding the damage part of the chromatin. Crystal structure of the monoubiquitinated FANCD2 alone is not available, therefore we have modelled the optimized structure of the human monoubiquitinated (Lys 561) FANCD2. As there is no suitable software or web server we have developed a method for building up monoubiquitinated product and validated on simplest monoubiquitinated protein, diubiquitin. We have predicted the structure of human monoubiquitinated FANCD2 by using our method and studied the interaction with DNA by docking studies. Molecular Dynamics (MD) simulation has been used to understand the stability of the structure. Large structural differences have been observed between FANCD2 and monoubiquitinated FANCD2. Docking studies with DNA suggest that the binding site varies for the FANCD2 and monoubiquitinated FANCD2. Communicated by Ramaswamy H. Sarma

description: Sub-Doppler, saturation dip, spectra of lines in the $v_1 + v_3$, $v_1 + 2v_4$ and $v_3 + 2v_4$ bands of $^{14}$NH$_3$ have been measured by frequency comb-referenced diode laser absorption spectroscopy. The observed spectral line widths are dominated by transit time broadening, but show resolved or partially-resolved hyperfine splittings that are primarily determined by the $^{14}$N quadrupole coupling. Modeling of the observed line shapes based on the known hyperfine level structure of the ground state of the molecule shows that, in nearly all cases, the excited state level has hyperfine splittings similar to the same rotational level in the ground state. The data provide accurate frequencies for the line positions and easily separate lines overlapped in Doppler-limited spectra. The observed hyperfine splittings can be used to make and confirm rotational assignments and ground state combination differences obtained from the measured frequencies are comparable in accuracy to those obtained from conventional microwave spectroscopy. One upper state level shows very clear differences from the expected splittings. Examination of the known vibration-rotation level structure shows there is a near degeneracy between this level in $v_1+v_3$ and a rotational level in the $v_1 + 2v_4$ manifold which is of the appropriate symmetry to be mixed by magnetic hyperfine terms that couple ortho- and para- forms of the molecule.

Determinants of Agricultural Export in Ethiopia
Creators: name: Tekeste, Samuel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: This paper identified some of the main determinants of agricultural export in Ethiopia for the period 1980-2010. To test empirically the relationship between agricultural export performance and its major selected determinants such as terms of trade, gross domestic product, domestic price, world price, kilometers paved roads and fertilizer input import over a period; cointegration and error correction approaches in the regression analysis were used. The results from the cointegration and error correction models revealed that all the above listed explanatory variables significantly affected agricultural export performance in the long run except domestic price. In the short run, gross domestic product (GDP) became insignificant and negative in sign which was unexpected. Domestic price was also insignificant like in the case of long run. However, except these two variables other variables were found to significantly affect the agricultural export performance of the country. On the other hand, out of the variables significantly affected agricultural export both in the long run and short run; terms of trade, world price, fertilizer input import over a period and kilometers of paved roads affected agricultural export positively as expected. Especially when we look at the magnitude by which kilometers of paved road affected the dependent variable both in the long run and in the short run positively and significantly, it can be regarded as one of the key finding in this study.
Sum Secrecy Rate Maximization for Full-Duplex Two-Way Relay Networks Using Alamouti-based Rank-Two Beamforming

description: Consider a two-way communication scenario where two single-antenna nodes, operating under full-duplex mode, exchange information to one another through the aid of a (full-duplex) multi-antenna relay, and there is another single-antenna node who intends to eavesdrop. The relay employs artificial noise (AN) to interfere the eavesdropper's channel, and amplify-forward (AF) Alamouti-based rank-two beamforming to establish the two-way communication links of the legitimate nodes. Our problem is to optimize the rank-two beamformer and AN covariance for sum secrecy rate maximization (SSRM). This SSRM problem is nonconvex, and we develop an efficient solution approach using semidefinite relaxation (SDR) and minorization-maximization (MM). We prove that SDR is tight for the SSRM problem and thus introduces no loss. Also, we consider an inexact MM method where an approximately but computationally cheap MM solution update is used in place of the exact update in conventional MM. We show that this inexact MM method guarantees convergence to a stationary solution to the SSRM problem. The effectiveness of our proposed approach is further demonstrated by an energy-harvesting scenario extension, and by extensive simulation results.

description: Many microorganisms, with phytoplankton and zooplankton as prominent examples, display phototactic behaviour, that is, the ability to perform directed motion within a light gradient. Here we experimentally demonstrate that sensing of light gradients can also be achieved in a system of synthetic photo-activated microparticles being exposed to an inhomogeneous laser field. We observe a strong orientational response of the particles because of diffusiophoretic torques, which in combination with an intensity-dependent particle motility eventually leads to phototaxis. Since the aligning torques saturate at high gradients, a strongly rectified particle motion is found even in periodic asymmetric intensity landscapes. Our results are in excellent agreement with numerical simulations of a minimal model and should similarly apply to other particle propulsion mechanisms. Because light fields can be easily adjusted in space and time, this also allows to extend our approach to dynamical environments.

description: A detailed computational study covering density functional theory (DFT), molecular docking, and molecular dynamics (MD) simulations of some spirocyclic compounds interacting with a B-DNA has been performed. DFT calculations were performed using the B3LYP functional with 6-311++G(d,p) basis set and were used to identify the electrophilic and nucleophilic centers in electrostatic forces. NMR results were in agreement with previous experimental data and approved the reliability of the used method and basis set. The in silico screening results showed that spirocyclic compounds fulfill the Lipinski's rule of five and can be developed as potential oral bioavailable drug candidates. Based on molecular docking results, the binding affinities follow the 4c < 4d < 4a = 4b < 4e < 4g < 4f order and ranged from −8.6 to −9.7 kcal/mol indicating a reasonably favorable interaction between DNA and investigated compounds. The adducts were stabilized by hydrophobic and hydrogen bonding interactions. The MD simulations performed for 100 ns and the results are reported in terms of variables such as root-mean-square deviation (RMSD), root-mean-square fluctuation (RMSF), center of mass (COM) separation distance between DNA and ligands, intermolecular hydrogen bonds, and radial distribution functions (RDF). The MD simulations demonstrated that compounds 4a and 4d bind into the minor groove of 1BNA and may act as potential biological probes for B-DNA. Communicated by Ramaswamy H. Sarma
