description: The so-called great dimming event of alpha Ori in late 2019 and early 2020 sparked our interest in the behaviour of chromospheric activity during this period. To study the timeline of chromospheric activity, we derive a S_MWO time series of TIGRE and Mount Wilson values, and we compare this long time series with photometric data from the AAVSO database. In addition, we determine the absolute and normalised excess flux of the Ca II H&K lines. To do so, we estimate the changing effective temperature from TIGRE spectra and find a clear drop of about 80 K between November 2019 and February 2020, which coincides with the minimum of visual brightness. During the same period, the S-index increased significantly, yet this is a mere contrast effect, because the normalised excess flux of the Ca II H&K lines did not change significantly. However, the latter dropped immediately after this episode. Comparing the combined S_MWO values and visual magnitude time series, we find a similar increase in the S-index during another noticeable decrease in the visual magnitude of alpha Ori, which took place in 1984 and 1985. To also probe the dynamics of the upper photosphere, we analysed the lines in 6251-6263 A and found core distance varies which shows a relation with the great dimming event. This type of variation could be caused by rising and sinking cool plumes as a temporary spill-over of convection on alpha Ori. Based on our study, we conclude that the cause for the great dimming is located in the photosphere. Furthermore, the long-term spectroscopic and photometric time series suggests that this great dimming does not appear to be a unique phenomenon, but rather that such dimmings do occur more frequently, which motivates further monitoring of alpha Ori with facilities such as TIGRE.

description: We consider the scattering of gravitational waves off a Schwarzschild black hole in $f(R)$ gravity. We show that the reflection and transmission coefficients for tensor waves are the same as in General Relativity. While the scalar waves, which are not present in General Relativity, demonstrate interesting features. The equation that governs these scalar waves can be reduced to a Volterra integral equation. Analysis of this equation shows that a larger fraction of these waves are reflected compared to what one obtains for tensors. This may provide a novel observational signature for fourth order gravity.

description: The development of quantum technologies present important challenges such as the need for fast and precise protocols for implementing quantum operations. Shortcuts to adiabaticity (STA) are a powerful tool for achieving these goals, as they enable us to perform an exactly adiabatic evolution in finite time. In this paper we present a shortcut to adiabaticity for the control of an optomechanical cavity with two moving mirrors. Given reference trajectories for the mirrors, we find analytical expressions that give us effective trajectories which implement a STA for the quantum field inside the cavity. We then solve these equations numerically for different reference protocols, such as expansions, contractions and rigid motions; thus confirming the successful implementation of the STA and finding some general features of these effective trajectories.

Year: 2012

description: Background: In some countries the use of Khat is widespread. The use or misuse of khat is increasingly prevalent in Ethiopia. College and University students consume khat to get mental alertness and to work hard in their academic endeavours. Most of the studies concerning khat chewing were done on community based studies and high school based as well as psychiatric effects of khat: less was done among University students. Objective: The study was aimed to assess the prevalence and associated factors of Khat chewing among Undergraduate Adama University Students. Methodology: A cross-sectional study using self administered questionnaire was conducted on population sample size determined by using single population proportion formula in January 2012.By using multi stage sampling technique followed by simple random sampling one department was selected from each school. Then, by simple random sampling the sampled students were selected proportional to their year of study and class size. Questions regarding demographic variables, academic and environmental factors were included in the survey. Data quality was controlled by pre-test, supervision, translation and training data collectors. Completed data were coded and entering into EPI info version 3.5.1 and analyzed by SPSS version 16. Odds Ratio with 95% CI and multiple logistic regression analysis were used. Results: A total of 728 students participated giving a response rate of 95.3%. The lifetime and current prevalence of khat chewing were found to be 27.7% and 20.7% respectively. Being male (AOR=1.95; 95% CI 1.10-3.47), monthly pocket money (AOR=1.52; 95%CI=1.01-2.28), family history of khat chewing (AOR=1.72; 95%CI= 1.14-2.59) and friend chewing khat (AOR=1.70; 95% CI= 1.12-2.58) were associated factors for khat chewing (p<0.05). Conclusion and Recommendation: The prevalence of khat chewing among Adama University students were high compared to other studies done in similar settings. Therefore, there is a need for early intervention that targets university students to reduce impact of peer pressure, family history of khat chewing and proper management of money. To realize this involvement and participation of policy makers, ministry of education, universities and parents is mandatory.

description: We investigate the impact of the direct searches for SUSY at LHC Run I on the naturalness of the Next-to-Minimal Supersymmetric Standard Model (NMSSM). For this end, we first scan the vast parameter space of the NMSSM to get the region where the fine tuning measures $Δ_Z$ and $Δ_h$ at the electroweak scale are less than about 50, then we implement by simulations the constraints of the direct searches on the parameter points in the region. Our results indicate that although the direct search experiments are effective in excluding the points, the parameter intervals for the region and also the minimum reaches of $Δ_Z$ and $Δ_h$ are scarcely changed by the constraints, which implies that the fine tuning of the NMSSM does not get worse after LHC Run I. Moreover, based on the results we propose a natural NMSSM scenario where the lightest neutralino $\tildeχ_1^0$ as the dark matter (DM) candidate is Higgsino-dominated. In this scenario, $Δ_Z$ and $Δ_h$ may be as low as 2 without conflicting with any experimental constraints, and intriguingly $\tildeχ_1^0$ can easily reach the measured DM relic density due to its significant Singlino component. We exhibit the features of the scenario which distinguish it from the other natural SUSY scenario, including the properties of its neutralino-chargino sector and scalar top quark sector. We emphasize that the scenario can be tested either through searching for $3 l + E_T^{miss}$ signal at 14 TeV LHC or through future DM direct detection experiments.

description: The bulk photovoltaic effect that is intimately associated with crystalline symmetry has been extensively studied in various nonmagnetic materials, especially ferroelectrics with a switchable electric polarization. In order to further engineer the symmetry, one could resort to spin-polarized systems possessing an extra magnetic degree of freedom. Here, we investigate the bulk photovoltaic effect in two-dimensional magnetic sliding ferroelectric (MSFE) systems, illustrated in VSe2, FeCl2, and CrI3 bilayers. The transition metal elements in these systems exhibit intrinsic spin polarization, and the stacking mismatch between the two layers produce a finite out-of-plane electric dipole. Through symmetry analyses and first-principles calculations, we show that photoinduced in-plane bulk photovoltaic current can be effectively tuned by their magnetic order and the out-of-plane dipole moment. The underlying mechanism is elucidated from the quantum metric dipole distribution in the reciprocal space. The ease of the fabrication and manipulation of MSFEs guarantee practical optoelectronic applications.

Die Auswertung der Ergebnisse erfolgte im Kontext der Bioethikdebatte um die pränatale und präimplantive Diagnostik in Deutschland. Die Schwerpunkte lagen in der Bewertung von Indikationen, Technikfolgen und ethisch-moralischen Streitfragen zu einer möglichen Etablierung dieser Technik. Die Ergebnisse zeigten, dass beide Expertengruppen die PID wie auch die PND sehr befürworteten. 94% der Humangenetiker und 97% der Reproduktionsmediziner sprachen sich für eine Zulassung der PID in Deutschland aus. Zusätzlich konnte gezeigt werden, dass sich die PID aus Sicht der hier befragten Experten bei allen überprüften Indikationen als die ethisch-moralisch akzeptablere Technik im Vergleich zur PND mit anschließendem Schwangerschaftsabbruch darstellte. Es bleibt zu hoffen, dass diese Untersuchung zu einer besseren Evaluation der bioethischen Theorie und Praxis im Rahmen einer kontextsensitiven Ethik sowie zu einer konstruktiven und demokratischen Lösung der PID-Kontroverse und anderer aktueller Problemfelder der Biomedizin beitragen kann.
description: The present work deals with the representative survey of German human geneticists and reproductive medicine experts/gynecologists regarding their views of PGD and PND. The results were evaluated in the context of the bioethical debate on prenatal and preimplantation genetic diagnosis taking place in Germany. The work focuses on the evaluation of indications, consequences of technical progress and the ethical-moral issues on a possible establishment of this technology in Germany. The results indicate that both expert groups clearly supported PGD as well as PND. 94% of human geneticists and 97% of reproductive medicine experts declared that they were in favour of a legalization of PGD in Germany. Additionally, it was shown that the PGD was – in the view of the experts interviewed herein and regarding all tested indications - judged to be the ethically and morally more acceptable technique compared to PND followed by an abortion.It is to be hoped that this study may contribute to a better evaluation of bioethical theory and practice within a context-sensitive ethic as well as to a constructive and democratic solution regarding the controversy about PGD and other topical problems within biomedicine.

description: We present a new derivation of the Milky Way's current star formation rate (SFR) based on the data of the Hi-GAL Galactic plane survey. We estimate the distribution of the SFR across the Galactic plane from the star-forming clumps identified in the Hi-GAL survey and calculate the total SFR from the sum of their contributions. The estimate of the global SFR amounts to $2.0 \pm 0.7$~M$_{\odot}$~yr$^{-1}$, of which $1.7 \pm 0.6$~M$_{\odot}$~yr$^{-1}$ coming from clumps with reliable heliocentric distance assignment. This value is in general agreement with estimates found in the literature of last decades. The profile of SFR density averaged in Galactocentric rings is found to be qualitatively similar to others previously computed, with a peak corresponding to the Central Molecular Zone and another one around Galactocentric radius $R_\mathrm{gal} \sim 5$~kpc, followed by an exponential decrease as $\log(Σ_\mathrm{SFR}/[\mathrm{M}_\odot~\mathrm{yr}^{-1}~\mathrm{kpc}^{-2}])=a\,R_\mathrm{gal}/[\mathrm{kpc}]+b $, with $a=-0.28 \pm 0.01$. In this regard, the fraction of SFR produced within and outside the Solar circle is 84\% and 16\%, respectively; the fraction corresponding to the far outer Galaxy ($R_\mathrm{gal} > 13.5$~kpc) is only 1\%. We also find that, for $R_\mathrm{gal}>3$~kpc, our data follow a power law as a function of density, similarly to the Kennicutt-Schmidt relation. Finally, we compare the distribution of the SFR density across the face-on Galactic plane and those of median parameters, such as temperature, luminosity/mass ratio and bolometric temperature, describing the evolutionary stage of Hi-GAL clumps. We found no clear correlation between the SFR and the clump evolutionary stage.

description: Within the dynamically cold low inclination portion of the Classical Kuiper Belt, there exists a population of weakly bound binary systems with a number of unusual properties; most notable of which is their extremely wide orbital separations; beyond 7% of their Hill radii. The stability and evolution of these Ultra-Wide Trans-Neptunian Binaries (TNBs) have, in the past, been studied extensively under the assumption that the primary evolving mechanisms are interactions between the binary components and impacting Trans-Neptunian Objects (TNOs). Here, we instead study their evolution as driven by the gravitational perturbations of close passing but non-impacting TNOs. By simulating these passages, we show that the aggregate effects of encounters over billions of years have a significant effect on Kuiper Belt binary evolution. Such processes can lead to tight binaries widening significantly over time, approaching and sometimes surpassing the separation of the widest known TNBs. We also find that the eccentricity and inclination distributions of observed Ultra-Wide TNBs can be sampled from such widened binaries. While we are unable to produce enough wide binaries to explain their abundance, the orbital properties of ones we do produce are consistent with known wide binaries.

Year: 2019

description: Background: Risky sexual behavior accounts for a large number of opportunities for acquiring HIV infection and other STIs. Students of higher learning institutions are with multiple sociocultural backgrounds and begin independent life at younger age. Methods: A cross-sectional study was conducted among 588 randomly selected undergraduate students from private universities in Addis Ababa, from December 2018 to October 2019. Study participants were selected using multi stage stratified sampling technique. Interviewer administer pretested structured questionnaire was used to collect the data. The data was entered into Epi-data version 4.4.2.1 then exported to SPSS version 21 for analysis. Descriptive analysis (Frequency, mean, and proportion) and regression analysis was done to summarize findings. Results: Overall, 32.6% of study participants started sexual intercourse at the time of study. The median age at first sexual intercourse was 18.3. About 66.7% of respondents were engaged in risky sexual behavior in their life time. Students who attended their high school education at private schools (AOR=3.160; 95% CI= 1.406, 7.103), first age at sex (AOR = 0.075; 95% CI = 0.030, 0.190), and condom use at first-time sexual intercourse (AOR = 5.594; 95% CI = 2.223, 14.076) were significantly associated with risky sexual behavior. Conclusions: The finding of this study identified that significant numbers of students engaged in risky sexual behaviors by having multiple sexual partner and inconsistence/non-use of condom in their life time. Therefore, understanding factors associated with risky sexual behavior is important for implementing comprehensive interventions and prevent multiple risk factors among private university students.

description: Nova V5856 Sagittarii is unique for having remained more than nine magnitudes above its pre-outburst brightness for more than six years. Extensive visible and IR spectra from the time of outburst to the present epoch reveal separate emitting regions with distinct spectral characteristics. Permitted emission lines have both broad and narrow components, whereas the forbidden line profiles are almost entirely broad. The permitted line components frequently display P Cygni profiles indicating high optical depth, whereas the broad components do not show detectable absorption. The densities and velocities deduced from the spectra, including differences in the O I 7773 and 8446 lines, are not consistent with an on-going wind. Instead, the prolonged high luminosity and spectral characteristics are indicative of a post-outburst common envelope that enshrouds the binary, and is likely the primary source of the visible and IR emission.

description: In a recent comment by Fernández, it has been argued that our solution method of an effective Hamiltonian based on the characteristic polynomial [Phys. Lett. A 443 (2022) 128215] had been developed several years earlier by Fried and Ezra [J. Chem. Phys. 90 (1989) 6378]. We show here several important differences between our treatment and the resummation method proposed previously by Fried and Ezra.

description: We present fully GRMHD simulations of the merger of binary neutron star (BNS) systems. We consider BNSs producing a hypermassive neutron star (HMNS) that collapses to a spinning black hole (BH) surrounded by a magnetized accretion disk in a few tens of ms. We investigate whether such systems may launch relativistic jets and power short gamma-ray bursts. We study the effects of different equations of state (EOSs), different mass ratios, and different magnetic field orientations. For all cases, we present a detailed investigation of the matter dynamics and of the magnetic field evolution, with particular attention to its global structure and possible emission of relativistic jets. The main result of this work is that we found the formation of an organized magnetic field structure. This happens independently of EOS, mass ratio, and initial magnetic field orientation. We also show that those models that produce a longer-lived HMNS lead to a stronger magnetic field before collapse to BH. Such larger fields make it possible, for at least one of our models, to resolve the MRI and hence further amplify the magnetic field. However, by the end of our simulations, we do not observe a magnetically dominated funnel and hence neither a relativistic outflow. With respect to the recent simulations of Ruiz et al 2016, we evolve models with lower and more realistic initial magnetic field strengths and, because of computational reasons, we do not evolve the accretion disk for the long timescales that seem to be required in order to see a relativistic outflow. Since all our models produce a similar ordered magnetic field structure, we expect that the results found in Ruiz et al 2016, where they only considered an equal-mass system with an ideal fluid EOS, should be general and, at least from a qualitative point of view, independent from mass-ratio, magnetic field orientation, and EOS.

description: We present finite-element numerical algorithms for the identification of vortices in quantum fluids described by a macroscopic complex wave function. Their implementation using the free software FreeFem++ is distributed with this paper as a post-processing toolbox that can be used to analyse numerical or experimental data. Applications for Bose-Einstein condensates (BEC) and superfluid helium flows are presented. Programs are tested and validated using either numerical data obtained by solving the Gross-Pitaevskii equation or experimental images of rotating BEC. Vortex positions are computed as topological defects (zeros) of the wave function when numerical data are used. For experimental images, we compute vortex positions as local minima of the atomic density, extracted after a simple image processing. Once vortex centers are identified, we use a fit with a Gaussian to precisely estimate vortex radius. For vortex lattices, the lattice parameter (inter-vortex distance) is also computed. The post-processing toolbox offers a complete description of vortex configurations in superfluids. Tests for two-dimensional (giant vortex in rotating BEC, Abrikosov vortex lattice in experimental BEC) and three-dimensional (vortex rings, Kelvin waves and quantum turbulence fields in superfluid helium) configurations show the robustness of the software. The communication with programs providing the numerical or experimental wave function field is simple and intuitive. The post-processing toolbox can be also applied for the identification of vortices in superconductors.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1996

description: Ethiopia is one of the developing countries where malnutrition and communicable diseases represent the major health problems. A community based cross sectional study was done in Adami-Tulu Woreda to determine and identify factors influencing nutritional status of children between 6 and 59 months of age in rural communities. The result showed a high prevalence of malnutrition. Out of 568 children who were involved in the study, 255 (44.9%) were well-nourished and 313 (55.1%) malnourished, 264 (43.3%) under-weight, 210 (37%) stunted and 103 (18.1%) wasted. The rates of sever and moderate malnutrition were highest when using weight-for-age scale. Age of the child, ethnicity, availability of latrine, family income, birth order, frequency of feeding and weaning age were significantly associated with nutritional status. As the prevalence of malnutrition among the children was found high and it is recommended that nutritional intervention aiming at altering the local factors be implemented all relevant social sectors in a coordinated way.

description: We present a disc-halo N-body model of the low surface brightness galaxy UGC 628, one of the few systems that harbours a "slow" bar with a ratio of corotation radius to bar length of $\mathcal{R} \equiv R_c/a_b \sim 2$. We select our initial conditions using SDSS DR10 photometry, a physically motivated radially variable mass-to-light ratio profile, and rotation curve data from the literature. A global bar instability grows in our submaximal disc model, and the disc morphology and dynamics agree broadly with the photometry and kinematics of UGC 628 at times between peak bar strength and the onset of buckling. Prior to bar formation, the disc and halo contribute roughly equally to the potential in the galaxy's inner region, giving the disc enough self gravity for bar modes to grow. After bar formation there is significant mass redistribution, creating a baryon dominated inner and dark matter dominated outer disc. This implies that, unlike most other low surface brightness galaxies, UGC 628 is not dark matter dominated everywhere. Our model nonetheless implies that UGC 628 falls on same the relationship between dark matter fraction and rotation velocity found for high surface brightness galaxies, and lends credence to the argument that the disc mass fraction measured at the location where its contribution to the potential peaks is not a reliable indicator of its dynamical importance at all radii.

description: Background: Sexually Transmitted Infections (STIs) are a group of infections transmitted through unsafe sexual intercourse. Promotion of condom use is the simplest and cost effective strategies for preventing sexually transmitted diseases. However, condom utilization among adults in Ethiopia is not satisfactory. Objectives: To assess knowledge, attitude and practice towards sexually transmitted infections and condom utilization among daily laborer adults in the construction sector. Methods: A cross sectional study was conducted in June 2016 to may 2017 among daily laborers engaged in construction sector in the Laga Tafo area. Study participants were selected by systematic random sampling. Data was collected by standardized quastionare and enter by Epi info. By using SPSS version 21.1 data were analyzed in bivariate and multivariate logistic regression. Results: A total of 364 daily laborers were participated in the study. According to the recent study 245(67.3%) and 285(78.3%) of respondents were knowledgeable about STIs and condom use respectively. Incase of attitude towards STIs and condom use more than half of study participants had favorable attitude towards STIs and condom use. Only 165(48.2%) sexually active participants were ever used condom during sexual intercourse. Of which ever used condom 109 of them consistently used condom with in the past six months. Among currently sexually active respondents the rate of self reported STD was 10.7%. Respondents those who do not chew khat before sexual intercourse 0.122 time less likely to have history of STIs (AOR=0.122, 95% CI :( 0.053, 0.280). Participants those who do not have formal education 0.062 times less likely to use condom than those who were completed secondary and above [AOR = 0.062, 95% CI, (0.021, 0.181)). Conclussion and recommendation: Though of large proportion of study participants were having awareness on STIs and condom use; majority of them practicing risky sexual practice. There was a gap between knowledge on STIs and sexual behavior of respondents. Therefore, health education program aimed at bringing behavioral change should be planned and implemented.

description: A multi-decade record of ground-based mid-infrared (7-25 $μ$m) images of Saturn is used to explore seasonal and non-seasonal variability in thermal emission over more than a Saturnian year (1984-2022). Thermal emission measured by 3-m and 8-m-class observatories compares favourably with synthetic images based on both Cassini-derived temperature records and the predictions of radiative climate models. 8-m class facilities are capable of resolving thermal contrasts on the scale of Saturn's belts, zones, polar hexagon, and polar cyclones, superimposed onto large-scale seasonal asymmetries. Seasonal changes in brightness temperatures of $\sim30$ K in the stratosphere and $\sim10$ K in the upper troposphere are observed, as the northern and southern polar stratospheric vortices (NPSV and SPSV) form in spring and dissipate in autumn. The timings of the first appearance of the warm polar vortices is successfully reproduced by radiative climate models, confirming them to be radiative phenomena, albeit entrained within sharp boundaries influenced by dynamics. Axisymmetric thermal bands (4-5 per hemisphere) display temperature gradients that are strongly correlated with Saturn's zonal winds, indicating winds that decay in strength with altitude, and implying meridional circulation cells forming the system of cool zones and warm belts. Saturn's thermal structure is largely repeatable from year to year (via comparison of infrared images in 1989 and 2018), with the exception of low-latitudes. Here we find evidence of inter-annual variations because the equatorial banding at 7.9 $μ$m is inconsistent with a $\sim15$-year period for Saturn's equatorial stratospheric oscillation, i.e., it is not strictly semi-annual. Finally, observations between 2017-2022 extend the legacy of the Cassini mission, revealing the continued warming of the NPSV during northern summer. [Abr.]

description: We study the formation of galactic outflows from supernova explosions (SNe) with the moving-mesh code AREPO in a stratified column of gas with a surface density similar to the Milky Way disk at the solar circle. We compare different simulation models for SNe placement and energy feedback, including cosmic rays (CR), and find that models that place SNe in dense gas and account for CR diffusion are able to drive outflows with similar mass loading as obtained from a random placement of SNe with no CRs. Despite this similarity, CR-driven outflows differ in several other key properties including their overall clumpiness and velocity. Moreover, the forces driving these outflows originate in different sources of pressure, with the CR diffusion model relying on non-thermal pressure gradients to create an outflow driven by internal pressure and the random-placement model depending on kinetic pressure gradients to propel a ballistic outflow. CRs therefore appear to be non-negligible physics in the formation of outflows from the interstellar medium.

Probing quasar lifetimes with proximate $21$-centimetre absorption in the diffuse intergalactic medium at redshifts $z\geq 6$

description: Enhanced ionizing radiation in close proximity to redshift $z\gtrsim 6$ quasars creates short windows of intergalactic Ly$α$ transmission blueward of the quasar Ly$α$ emission lines. The majority of these Ly$α$ near-zones are consistent with quasars that have optically/UV bright lifetimes of $t_{\rm Q}\sim 10^{5}-10^{7}\rm\,yr$. However, lifetimes as short as $t_{\rm Q}\lesssim 10^{4}\rm\,yr$ appear to be required by the smallest Ly$α$ near-zones. These short lifetimes present an apparent challenge for the growth of $\sim 10^{9}\rm\,M_{\odot}$ black holes at $z\gtrsim 6$. Accretion over longer timescales is only possible if black holes grow primarily in an obscured phase, or if the quasars are variable on timescales comparable to the equilibriation time for ionized hydrogen. Distinguishing between very young quasars and older quasars that have experienced episodic accretion with Ly$α$ absorption alone is challenging, however. We therefore predict the signature of proximate 21-cm absorption around $z\gtrsim 6$ radio-loud quasars. For modest pre-heating of intergalactic hydrogen by the X-ray background, where the spin temperature $T_{\rm S} \lesssim 10^{2}\rm\,K$ prior to any quasar heating, we find proximate 21-cm absorption should be observable in the spectra of radio-loud quasars. The extent of the proximate 21-cm absorption is sensitive to the integrated lifetime of the quasar. Evidence for proximate 21-cm absorption from the diffuse intergalactic medium within $2-3\rm\,pMpc$ of a (radio-loud) quasar would be consistent with a short quasar lifetime, $t_{\rm Q}\lesssim 10^{5}\rm\,yr$, and would provide a complementary constraint on models for high redshift black hole growth.

Quasi-Dirac neutrinos at the LHC

description: Lepton number violation is searched for at the LHC using same-sign leptons plus jets. The standard lore is that the ratio of same-sign lepton to opposite-sign lepton events, $R_{ll}$, is equal to $R_{ll}=1$ ($R_{ll}=0$) for Majorana (Dirac) neutrinos. We argue that for "quasi-Dirac" neutrinos, $R_{ll}$ can have any value between 0 and 1, the precise value being controlled by the mass splitting versus the width of the quasi-Dirac resonances. A measurement of $R_{ll}\neq 0,1$ would then contain valuable information about the origin of neutrino masses. We consider as an example the inverse seesaw mechanism in a left-right symmetric scenario, which is phenomenologically particularly interesting since all the heavy states in the high energy completion of the model could be within experimental reach. A prediction of this scenario is a correlation between the values of $R_{ll}$ and the ratio between the rates for heavy neutrino decays into standard model gauge bosons, and into three body final states $ljj$ mediated by off-shell $W_R$ exchange.
