description: Today's science provides quite a lean picture of time as a mere geometric evolution parameter. I argue that time is much richer. In particular, I argue that besides the geometric time, there is creative time, when objective chance events happen. The existence of the latter follows straight from the existence of free-will. Following the french philosopher Lequyer, I argue that free-will is a prerequisite for the possibility to have rational argumentations, hence can't be denied. Consequently, science can't deny the existence of creative time and thus that time really passes.

description: We report the discovery of two Li-rich giants, with A(Li) ~ 1.50, in an analysis of a sample of 40 giants of the open cluster Trumpler 20 (with turnoff mass ~ 1.8 Msun). The cluster was observed in the context of the Gaia-ESO Survey. The atmospheric parameters and Li abundances were derived using high-resolution UVES spectra. The Li abundances were corrected for nonlocal thermodynamical equilibrium (non-LTE) effects. Only upper limits of the Li abundance could be determined for the majority of the sample. Two giants with detected Li turned out to be Li rich: star MG 340 has A(Li) non-LTE = 1.54 \pm 0.21 dex and star MG 591 has A(Li) non-LTE = 1.60 \pm 0.21 dex. Star MG 340 is on average ~ 0.30 dex more rich in Li than stars of similar temperature, while for star MG 591 this difference is on average ~ 0.80 dex. Carbon and nitrogen abundances indicate that all stars in the sample have completed the first dredge-up. The Li abundances in this unique sample of 40 giants in one open cluster clearly show that extra mixing is the norm in this mass range. Giants with Li abundances in agreement with the predictions of standard models are the exception. To explain the two Li-rich giants, we suggest that all events of extra mixing have been inhibited. This includes rotation-induced mixing during the main sequence and the extra mixing at the red giant branch luminosity bump. Such inhibition has been suggested in the literature to occur because of fossil magnetic fields in red giants that are descendants of main-sequence Ap-type stars.

description: Temperature of PV modules always has been a key parameter in order to understand and predict the efficiency of PV technologies. In this work, the analysis of the temperature trend of a selected set of colored BIPV modules is performed, with the aim of correlating the irradiance recorded through a pyranometer to the temperature of the modules, recorded through Pt100 temperature sensors. A description of the different aspects of BIPV concept is provided, and a simulation strategy is introduced to understand the power loss due to the presence of colored layer on the modules’ front glass. Furthermore, test facilities available at Eurac Research laboratories and the equipment used during the test campaign are described. As metric of measures, the Ross coefficient k is used to correlate the different PV systems to the temperature rise. The values found after a data calibration and filtering procedure are elaborated and compared with the outcomes of a standard not-colored BIPV installation, located in Bolzano. The modules’ temperature measured through Pt100 sensors have been then compared with the results of a thermographic analysis.

description: The work places of the contemporary organizations are dominated by the millennial workforces who are coming up with their own distinct needs, desires, characters and expectations. The old fashioned attraction and retention strategies of 'one-size-fits-all' would not be appropriate to the young workforce in today's multigenerational workforces. This study examined the effectiveness of managing the millennial workforce in Commercial Bank of Ethiopia: the case of Addis Ababa City Area. After a deep review of theoretical and empirical sources a conceptual framework of the study has been developed and then five independent variables have been identified to meet the intended purpose of the study. A cross sectional survey of self-administered questionnaires was prepared to collect relevant information from randomly selected 258 sample participants. Among this 248 questionnaires were effectively collected and analyzed. The collected data was analyzed by SPSS version 22 using descriptive statics and multiple regressions. Descriptive research design was deployed to describe what the situation looks like whereas correlation analysis was used to show the relation between dependent and independent variables. Hence, all independent variables have positive relationship or correlation with the dependent variable of attraction and retention. Based on the result of multiple linear regression variables like continuous feedback and recognition, management style, the nature of the work and opportunity for learning and career development have positive and significance effect on the management effectiveness of attraction and retention of the millennial work force. Finally conclusions have been dawn based upon it recommendations have been forwarded.

description: Influencer marketing is a growing phenomenon, with growth expected to continue and pour in across many different industries. This research identified and explored influencer marketing by combining it with purchase intention as a means of effectiveness measurement. The overall goal of this research was to assess the influencer marketing effectiveness in fashion consumers and, subsequently, find out what components behind influencer marketing help make it effective. This research used a deductive approach, identifying, analyzing, and combining existing theories. Afterward, a hypothesis was formulated and introduced, and a quantitative survey methodology was employed. The survey was carried out on 70 respondents using questions in the 5-Point Likert Scale format, and the data was analyzed using statistical methods such as correlation and regression analyses. Results obtained from the survey found that influencer marketing had a strong positive correlation with purchase intention increase (r=.712). Furthermore, the regression analysis implicated influencer marketing as a significant predictor of purchase intention (b-value of .843). Additional correlation analyses were carried out to answer the research question. It was concluded that trustworthiness (.707), similarity (.682), and credibility (.505) had the most notable correlation coefficient with purchase intention increase, while attractiveness (.446) had the least. The findings led to the acceptance of the research hypothesis.

description: The need for a more sustainable built environment is urgent and requires cost-efficient, smart and integrated renewable energy solutions. The surfaces of the buildings and environments we live and work in represent an enormous potential to generate sustainable energy. In order to exploit these surfaces to their full potential, it is essential to be able to predict the energy yield of a specific system. In the past years we have developed an aesthetic PV solution for façades that enables both visible and invisible integration. Recently these panels have been mounted on several façades in the Netherlands. A detailed monitoring system provides input parameters for a sophisticated model that calculates the energy yield of the system. The model results show a good overlap with the measurement data, allowing the model to be used for optimization of similar systems on other façades.

description: In this paper, we discuss the MSSM extended with one vector-like lepton doublets $L$-$\overline{L}$ and one right-handed neutrino $N$. The neutral vecotor-like sneutrino can be a candidate of dark matter. In order to avoid the interaction with the necleons by exchanging a $Z$-boson, the mass splitting between the real part and the imaginary part of the sneutrino field is needed. Compared with the MSSM sneutrino dark matter, the mass splitting between the vector-like sneutrino field can be more naturally acquired without large A-terms and constraints on the neutralino masses. We have also calculated the relic density and the elastic scattering cross sections with the neucleons in the cases that the dark matter particles coannihilate with or without the MSSM slepton doublets. The elastic scattering cross sections with the neucleons are well below the LUX bounds. In the case that the dark matter coannihilate with all the MSSM slepton doublets, the mass of the dark matter can be as light as 370 GeV.

description: In modern day marketing, different tools are used to promote the product and make the consumer aware of it. Celebrity endorsement is an advertising strategy whereby companies use people of public recognition as spokespersons for their products. Although a number of related researches have been carried out in different parts of the world, while limited were in Ethiopia. This study aims to address this gap. The target populations for the study were customers" of special branches of CBE found in Addis Ababa. All data were collected from customers through a structured questionnaire by convenience sampling (n=305). The study utilized both descriptive statistical analysis and multiple regression analysis using SPSS software. And also correlation analysis was used to identify the relationship among variables. The findings of this research showed that there was positive and statistically significant effect between celebrity endorsement and intention to purchase. The coefficients of the regression equation showed the magnitude and direction of the relationship among independent and dependent variables. This study also forwards recommendations and future studies.

description: The international standard IEC 61853-1 contains two procedures for the evaluation of PV module output (Pmp) over a range of irradiances (GPOA) and module temperatures (Tmod): a procedure for indoor labs and a procedure for outdoor measurements (we neglect the option of using a tracker, which is quite challenging for BIPV-systems). The data from the IEA PVPS Task 15 (Enabling Framework for the Acceleration of Building Integrated Photovoltaics, BIPV) roundrobin has been used for an in-depth analysis of the differences between the indoor and outdoor determined Pmp-matrix. Moreover, the variety in the matrices of the eight individual test sites in various parts of the world is investigated. The approach is based on specific filtering of the outdoor data and color plot the relevant parameters in 2D matrices (of GPOA and Tmod) including the statistics of all data points that are present in each bin of that matrix. Filtering on Angle Of Incidence (AOI) and distance to center of the bin has been applied to make the comparison as precise as possible. Even after this filtering it was found impossible to decrease the standard deviation (stdev) of all points within a bin to a value lower than 5% as requested from the standard. A more realistic criterium of 10% stdev is proposed to use. The systematic fluctuations within each bin are caused by environmental factors that were not controlled or measured in our round-robin. These factors are, in random order: non-uniformity of (i) GPOA and (ii) Tmod within the module area, (iii) thermal dynamics between the Tmod sensor on the back of the PV-module and the actual Tcell that determines Pmp, (iv) soiling, (v) spectral effects. In conclusion, following the indoor and outdoor procedure of the IEC 61853-1 does not give the same Pmp-matrix for a given (BI)PV-module type. Significant differences are observed and analyzed. These results show that it might be very challenging to use the outdoor procedure without tracker for the purpose of energy rating. Leading to the recommendation to use the indoor procedure for energy rating of PV-modules and use the outdoor procedure for a well-defined quantification of energy losses caused by the aforementioned fluctuating environmental factors always present in realistic (BI)PV-systems.

description: The dataset includes supporting information files for the article "Step-by-step replacement of cyano groups by tricyanovinyls – the influence on the acidity". The dataset contains results of optimization and frequency calculations carried out by Turbomole and Gaussian. Acid-base properties are the simplest expression of compounds’ coordinating ability. In the present work, we studied in silico how the gas-phase Brønsted acidity (GA) of several polycyano substituted compounds change when cyano (CN) groups are replaced by 1,2,2-tricyanovinyl (TCNV) groups in cyanic acid, dicyanoamine, cyanoform, and hydrogen tetracyanoborate. Different tautomers and conformers/isomers are included in the study. Gas-phase acidity values are compared with the acidities of different acids, including percyanated protonated mono-carba-closo-dodecaborate (carborane acid) and dodecaborate, as well as hydrogen cyanide and 1,2,2-tricyanoethene. An estimation of acetonitrile, dimethylsufoxide, and 1,2-dichloroethane acidities are presented using the COSMO-RS method and correlational analysis. The strongest acid with four TCNV groups shows remarkable acidic properties.

description: Broad emission lines in active galactic nuclei (AGNs) mainly arise from gas photoionized by continuum radiation from an accretion disk around a central black hole. The shape of the broad-line profile, described by ${\cal D}_{_{\rm Hβ}}={\rm FWHM}/σ_{_{\rm Hβ}}$, the ratio of full width at half maximum to the dispersion of broad H$β$, reflects the dynamics of the broad-line region (BLR) and correlates with the dimensionless accretion rate ($\dot{\mathscr{M}}$) or Eddington ratio ($L_{\rm bol}/L_{\rm Edd}$). At the same time, $\dot{\mathscr{M}}$ and $L_{\rm bol}/L_{\rm Edd}$ correlate with ${\cal R}_{\rm Fe}$, the ratio of optical Fe II to H$β$ line flux emission. Assembling all AGNs with reverberation mapping measurements of broad H$β$, both from the literature and from new observations reported here, we find a strong bivariate correlation of the form $\log(\dot{\mathscr{M}},L_{\rm bol}/L_{\rm Edd})=α+β{\cal D}_{_{\rm Hβ}}+γ{\cal R}_{\rm Fe},$ where $α=(2.47,0.31)$, $β=-(1.59,0.82)$ and $γ=(1.34,0.80)$. We refer to this as the fundamental plane of the BLR. We apply the plane to a sample of $z < 0.8$ quasars to demonstrate the prevalence of super-Eddington accreting AGNs are quite common at low redshifts.

description: We theoretically study the stability of more than one Majorana Fermion appearing in a $p$-wave superconductor/dirty normal metal/$p$-wave superconductor junction in two-dimension by using chiral symmetry of Hamiltonian. At the phase difference across the junction $φ$ being $π$, we will show that all of the Majorana bound states in the normal metal belong to the same chirality. Due to this pure chiral feature, the Majorana bound states retain their high degree of degeneracy at the zero energy even in the presence of random potential. As a consequence, the resonant transmission of a Cooper pair via the degenerate MBSs carries the Josephson current at $φ=π-0^+$, which explains the fractional current-phase relationship discussed in a number of previous papers.

Our study reveals that due to existence of both the multiple charge transfer pathways and helical symmetry, the transport properties are quite rigid under influence of envi- ronmental fluctuations which indicates that these biomolecules can serve as better alternatives in nanoelectronic devices than its other biological counterparts e.g., single-stranded DNA.

description: Recent studies indicate the feasibility of in-band fullduplex (FD) wireless communications, where a wireless radio transmits and receives simultaneously in the same band. Due to its potential to increase the capacity, analyzing the performance of a cellular network that contains full-duplex devices is crucial. In this paper, we consider maximizing the weighted sum-rate of downlink and uplink of a single cell OFDMA network which consists of an imperfect FD base-station (BS) and a mixture of half-duplex and imperfect full-duplex mobile users. To this end, the joint problem of sub-channel assignment and power allocation is investigated and a two-step solution is proposed. A heuristic algorithm to allocate each sub-channel to a pair of downlink and uplink users with polynomial complexity is presented. The power allocation problem is convexified based on the difference of two concave functions approach, for which an iterative solution is obtained. Simulation results demonstrate that when all the users and the BS are perfect FD nodes the network throughput could be doubled, Otherwise, the performance improvement is limited by the inter-node interference and the self-interference. We also investigate the effect of the self-interference cancellation capability and the percentage of FD users on the network performance in both indoor and outdoor scenarios.

description: Building integrated photovoltaic (BIPV) systems often operate under elevated temperatures and recurrent shading, which can accelerate performance loss. However, to date there are few reports on long-term performance of BIPV systems, as distinct from building applied PV (BAPV). This work reports the performance loss rates (PLR) after 5 to 10 years of operation of 55 rooftop BIPV systems in Switzerland. Median PLR was calculated to be 0.06% per year, indicating essentially no degradation, though there was a large spread of rates. Some systems were noted to be shaded at times, so a fault detection and diagnosis algorithm (FDDA) was developed to quantify shading severity. The FDDA used DC voltage and current and meteorological data as inputs and classified faults according to pre-defined thresholds. Faults caused by shading were grouped to determine the shading factor of each system. Shading factor showed a weak correlation to PLR, but delineated an upper limit, indicating it limits maximum achievable performance. Shading factor was found to increase in newer systems, and decrease with system capacity. Through innovative BIPV module and system design, the effect of shading and corresponding performance losses can be mitigated.

description: This study was undertaken with the objective of identifying the role of Addis Credit and Saving microfinance services in improving the total income of youth entrepreneurs in and around Woreda 14, Bole Sub city, Addis Ababa. The study relied on 315 clients who are actively working with the microfinance. Both quantitative and qualitative data collection strategies were employed in collecting relevant data for the study. The collected quantitative data were analyzed through SPSS statistical package. Likewise, the qualitative data were used to triangulate the data found via the questionnaire. The result of the study indicated the existence of positive relationship between the dependent variable, increase in total income and the independent variables, i.e., saving, credit, coaching and mentoring and innovative financial products. Compared to each other credit, coaching and mentoring and innovative financial products as major services rendered by the microfinance largely increase the total income of the clients. However, it has been found out that the total income of entrepreneurs is related to the saving amount of clients negatively. Overall, from the findings of the research it is possible to conclude that saving, credit, coaching and mentoring and innovative financial products have significant roles in improving the income of youth entrepreneurs. Further studies are recommended to explore the general economic, political and social landscapes that triggered to shift in the service of the sector as exhibited in this research. It is also recommended that future studies should show policy makers in the area of micro finance the relevance of examining what is happening on the ground against what is in the policy of establishing micro credit and saving institutions in the country.

description: The economics of both desalination and hydrogen production from water electrolysis are dominated by the cost of energy, so widespread availability of inexpensive solar energy incentivizes the desalination and electrolyzer industries to further advance their technologies. This study focuses on the coupling of the production of potable water, deionized water and hydrogen gas from seawater. We show that such coupling is cost-effective not only for hydrogen generation, but also for desalination, as desalination can use waste heat from electrolysis. Additionally, such coupling can be optimized when electrolyzers operate at high current density, using low-cost solar and/or wind electricity, as high density operation increases both hydrogen production and heat generation. Results of techno-economic analysis define thresholds of electricity pricing, current density, and operating temperature that make “green” electrolytic hydrogen cost-competitive with hydrogen from steam methane reforming. By using historical and projected hourly electricity prices in the US-southwest, we estimate that hydrogen can be produced from seawater in desalinationelectrolyzer systems at prices near $2/kg H2, achieving cost parity with currently produced hydrogen. In addition, thermal energy for desalination could be supplied by the electrolyzer, creating a closed loop for continuous green H2 production.

description: У представленій роботі аналізуються методичні підходи до визначення обсягу фінансування розвитку України в післявоєнний період. В умовах тривалої війни та значних економічних втрат, що супроводжують воєнні конфлікти, важливо сформувати ефективну стратегію відновлення, яка включає не лише оцінку безпосередніх фінансових потреб, а й довгострокове планування фінансування. Робота починається з огляду основних принципів визначення фінансування відновлення, акцентуючи увагу на важливості комплексного підходу, що включає аналіз прямого фінансового збитку, знищених і пошкоджених об'єктів інфраструктури, а також соціально-економічних наслідків війни.

Далі розглядається роль міжнародної допомоги та приватних інвестицій у фінансуванні відновлення. Міжнародні партнери мають критичне значення для забезпечення необхідних ресурсів, технічної підтримки та експертної оцінки. Важливим аспектом є мобілізація приватних інвестицій, які можуть стати значним джерелом капіталу для відновлення та модернізації економічної інфраструктури.

Продовження роботи присвячено питанням ефективного управління фінансуванням, зокрема, необхідності впровадження сучасних інформаційних систем для забезпечення прозорості витрат, дотримання стандартів підзвітності та боротьби з корупційними ризиками. Зокрема, акцентується на важливості створення механізмів моніторингу та звітності, що дозволяють оперативно відстежувати реалізацію проєктів та оцінювати їх ефективність.

Висновки роботи підкреслюють важливість інтеграції внутрішніх і зовнішніх ресурсів, ефективного управління та довгострокового планування для створення міцної основи для сталого розвитку України після завершення воєнних дій. Робота надає цілісне бачення методичних підходів до визначення обсягу фінансування для відновлення України, що є критично важливим для формування ефективних стратегій та політик у післявоєнний період.

description: The competition “Architectural Award Building-Integrated Solar Technology“ was organized for the eighth time since its establishment in summer 2000. With 159 schemes, there has been an increase in the number of countries taking part this time, with the jury reviewing competing schemes from 26 countries. Within the competition a first prize, four second prizes, a student prize and honorable mentions were awarded – with a total prize money of € 27,000. A fourstory school building in Luxemburg with PV and solar thermal systems was awarded with the first prize. There were second prizes for an apartment building in Zurich, a high rise building in Paris, a church in Germany and a solar home in India. Five honorable mentions (non-monetary prizes) were endowed: a historic building, an ice rink, a bike shelter, a solar folding roof (all in Switzerland) and an equipment barn in the USA. Many high-quality solutions indicate, that BIPV can often be applied and is able to produce electric energy and fulfill high architectural requirements.

description: Cities have been starting to adopt Circular Economy (CE) strategies to address resource efficiency and to tackle climate change. Combining sustainability and economic ambitions, municipalities aim to make their urban systems more resilient by giving incentives for closed resource loops in areas such as food, transport or construction. To address CE at an urban or regional scale, it is necessary to take into consideration the complexity of cities including the interwoven socio-ecological processes. This article briefly discusses two concepts for the implementation of CE at city-region level and introduces the Circular Berlin project as a new approach that has a strong focus on bottom-up mobilisation and community engagement. An in-depth description of the process and methods applied in Berlin is provided to demonstrate the effects of local community mobilisation within the context of CE. The Circular Berlin project is an alternative replicable model for CE implementation at city-region level that is based on the societal production of socio-technical systems. In a period of less than two years, more than 150 different organisations have been co-creating the CE agenda in Berlin. A database of relevant CE projects and stakeholders including their resource flows has been created and an active community has been formed that is leading the way in transforming the city and its systems towards a community-led CE.

description: We derive the exact n-point current expectation values in the Landauer-Buttiker non-equilibrium steady state of a multi terminal system with star graph geometry and a point-like defect localised in the vertex. The current cumulants are extracted from the connected correlation functions and the cumulant generating function is established. We determine the moments, show that the associated moment problem has a unique solution and reconstruct explicitly the corresponding probability distribution. The basic building blocks of this distribution are the probabilities of particle emission and absorption from the heat reservoirs, driving the system away from equilibrium. We derive and analyse in detail these probabilities, showing that they fully describe the quantum transport problem in the system.

description: We compare four sunspot-number data sequences against geomagnetic and terrestrial auroral observations. The comparisons are made for the original SIDC composite of Wolf-Zurich-International sunspot number [$R_{ISNv1}$], the group sunspot number [$R_{G}$] by Hoyt and Schatten (Solar Phys., 1998), the new "backbone" group sunspot number [$R_{BB}$] by Svalgaard and Schatten (Solar Phys., 2016), and the "corrected" sunspot number [$R_{C}$] by Lockwood at al. (J.G.R., 2014). Each sunspot number is fitted with terrestrial observations, or parameters derived from terrestrial observations to be linearly proportional to sunspot number, over a 30-year calibration interval of 1982-2012. The fits are then used to compute test sequences, which extend further back in time and which are compared to $R_{ISNv1}$, $R_{G}$, $R_{BB}$, and $R_{C}$. To study the long-term trends, comparisons are made using averages over whole solar cycles (minimum-to-minimum). The test variations are generated in four ways: i) using the IDV(1d) and IDV geomagnetic indices (for 1845-2013) fitted over the calibration interval using the various sunspot numbers and the phase of the solar cycle; ii) from the open solar flux (OSF) generated for 1845 - 2013 from four pairings of geomagnetic indices by Lockwood et al. (Ann. Geophys., 2014) and analysed using the OSF continuity model of Solanki at al. (Nature, 2000) which employs a constant fractional OSF loss rate; iii) the same OSF data analysed using the OSF continuity model of Owens and Lockwood (J.G.R., 2012) in which the fractional loss rate varies with the tilt of the heliospheric current sheet and hence with the phase of the solar cycle; iv) the occurrence frequency of low-latitude aurora for 1780-1980 from the survey of Legrand and Simon (Ann. Geophys., 1987). For all cases, $R_{BB}$ exceeds the test terrestrial series by an amount that increases as one goes back in time.

Mercury (Hg) in meteorites: variations in abundance, thermal release profile, mass-dependent and mass-independent isotopic fractionation

description: We have measured the concentration, isotopic composition and thermal release profiles of Mercury (Hg) in a suite of meteorites, including both chondrites and achondrites. We find large variations in Hg concentration between different meteorites (ca. 10 ppb to 14'000 ppb), with the highest concentration orders of magnitude above the expected bulk solar system silicates value. From the presence of several different Hg carrier phases in thermal release profiles (150 to 650 °C), we argue that these variations are unlikely to be mainly due to terrestrial contamination. The Hg abundance of meteorites shows no correlation with petrographic type, or mass-dependent fractionation of Hg isotopes. Most carbonaceous chondrites show mass-independent enrichments in the odd-numbered isotopes 199Hg and 201Hg. We show that the enrichments are not nucleosynthetic, as we do not find corresponding nucleosynthetic deficits of 196Hg. Instead, they can partially be explained by Hg evaporation and redeposition during heating of asteroids from primordial radionuclides and late-stage impact heating. Non-carbonaceous chondrites, most achondrites and the Earth do not show these enrichments in vapor-phase Hg. All meteorites studied here have however isotopically light Hg (δ202Hg = ~-7 to -1) relative to the Earth's average crustal values, which could suggest that the Earth has lost a significant fraction of its primordial Hg. However, the late accretion of carbonaceous chondritic material on the order of ~2%, which has been suggested to account for the water, carbon, nitrogen and noble gas inventories of the Earth, can also contribute most or all of the Earth's current Hg budget. In this case, the isotopically heavy Hg of the Earth's crust would have to be the result of isotopic fractionation between surface and deep-Earth reservoirs.

description: Using a Lagrangian framework, we study overdamping phenomena in gyroscopic systems composed of two components, one of which is highly lossy and the other is lossless. The losses are accounted by a Rayleigh dissipative function. As we have shown previously, for such a composite system the modes split into two distinct classes, high-loss and low-loss, according to their dissipative behavior. A principal result of this paper is that for any such system a rather universal phenomenon of selective overdamping occurs. Namely, first of all the high-loss modes are all overdamped, i.e., non-oscillatory, as are an equal number of low-loss modes. Second of all, the rest of the low-loss modes remain oscillatory (i.e., the underdamped modes) each with an extremely high quality factor (Q-factor) that actually increases as the loss of the lossy component increases. We prove that selective overdamping is a generic phenomenon in Lagrangian systems with gyroscopic forces and give an analysis of the overdamping phenomena in such systems. Moreover, using perturbation theory, we derive explicit formulas for upper bound estimates on the amount of loss required in the lossy component of the composite system for the selective overdamping to occur in the generic case, and give Q-factor estimates for the underdamped modes. Central to the analysis is the introduction of the notion of a "dual" Lagrangian system and this yields significant improvements on some results on modal dichotomy and overdamping. The effectiveness of the theory developed here is demonstrated by applying it to an electric circuit with a gyrator element and a high-loss resistor.
