description: La agroforestería ha sido reconocida por los organismos internacionales (FAO, ONU, UE) como un sistema de manejo sostenible de la tierra, que no se usa extensivamente en áreas templadas. Una de las principales razones de este hecho es la falta de conocimiento de la agroforestería por parte de los diferentes tipos de partes interesadas, como los responsables políticos, los agricultores y el público en general. Tener una definición clara de la agroforestería y las prácticas que conlleva ayudará a los sistemas agrícolas a avanzar hacia los objetivos de la agricultura climáticamente inteligente, incluidos aumentar el ingreso y la productividad agrícola, la adaptación y la resiliencia y la mitigación del cambio climático. La identificación de prácticas agroforestales debe estar enfocada en los principales usos de la tierra para ayudar a los agricultores a adoptar este sistema de uso sostenible en sus granjas. Se pueden identificar cinco prácticas agroforestales en Europa: silvoarable, silvopastoral, franjas riparias, cultivos forestales y huertos urbanos que pueden introducirse en más del 90% del área agrícola europea.
Signaling intensity depends on species-specific combination of EGFR and its ligand Gurken

Year: 2024

description: The distribution of the TGF-α ligand Gurken (GRK) evolved across Drosophila species form the Sophophora subgenus. These distributions can account for the diversity in the pattern of EGFR signaling and the formation of functional structures on the eggshells, including the respiratory dorsal appendages and the lumen-like dorsal ridge on the eggshells. Here, we focus on the mechanisms underlying the different outputs of EGFR signaling as a function of different combinations of GRKs and EGFRs from different Drosophila species, and the corresponding morphological changes in eggshells . Using CRISPR/Cas9, we swapped the loci of grk and egfr from D. melanogaster with their orthologues from D. nebulosa. We monitored the consequent changes in three transgenics: 1. D. melanogaster flies with transgenic D. nebulosa grk (nebGRK), 2. D. nebulosa egfr (nebEGFR), and 3. both nebGRK and nebEGFR. We found that nebGRK flies produce eggshells with dorsal appendages fused at the base, an indication of lower levels of EGFR signaling compared to the wild type fly. The nebEGFR flies showed a wild-type phenotype in most of their eggshells. Interestingly, nebGRK:nebEGFR flies showed strong dorsalized eggshells with lateral dorsal appendages. Also, an operculum that spans the entire circumference of the anterior end of the eggshell, including the ventral side. This data is consistent with the levels of EGFR activation and follicle cells patterning. We suggest that the co-evolution of EGFR and GRK can account for the level of EGFR in these backgrounds.

description: First-generation, Latinx, community college EOPS students who have experienced systematic discrimination and been placed on academic or progress probation do not have adequate support systems in place to ensure success. Not addressing this problem will exacerbate dropout rates of first-generation, Latinx students. The purpose of this phenomenological study was to explore perceptions of first-generation, Latinx, EOPS students who have been placed on academic or progress probation. Study participants included 11 first-generation, Latinx college students who were placed on academic or progress probation within three years of data collection. The study used semistructured interviews and simultaneous, value, and in vivo coding to analyze collected data. Results revealed study participants experienced barriers that prevented them from achieving academic success and had outside obligations that prevented focus and necessary time on school. Participants also indicated they had a negative reaction or experience, and thought about dropping out or did drop out after being placed on academic or progress probation. Recommendations from the study results include providing faculty-based validating experiences; creating more equitable policy processes; having counselors interact and guide students from a place of authentic care, compassion, and empathy; expanding existing support systems; and creating on-campus employment or philanthropic opportunities for first-generation, Latinx students.

description: As adult listeners, we comprehend the messages conveyed by spoken language with little effort. However, the ease of everyday conversation masks the perceptual and cognitive complexities involved in perceiving speech. Upon examination of the acoustic speech signal, it becomes immediately clear that this everyday skill is a demanding perceptual task.

description: Generalizing Courant's nodal domain theorem, the "Extended Courant property" is the statement that a linear combination of the first $n$ eigenfunctions has at most $n$ nodal domains. In a previous paper (Documenta Mathematica, 2018, Vol. 23, pp. 1561--1585), we gave simple counterexamples to this property, including convex domains. In the present paper, using some input from numerical computations, we pursue the investigation of the Extended Courant property with two new examples, the equilateral rhombus and the regular hexagon.
description: This version differs notably from arXiv 1803.00449v2 (15 Jun 2018). The part concerning Gelfand's approach to Sturm's 1D theorem has been removed (it is developed in arXiv:1807.03990 and will appear in the Moscow Math. Journal). The treatment of Sturm's 1D theorem in the periodic case has been removed. The short paragraph on product-like constructions has been removed as well. A section concerning the hexagon has been added. Minor changes with respect to hal-01718768, version 3 (7 Jun 2019). The paper focuses on the Extended Courant property for the equilateral rhombus and the regular hexagon.

description: We establish two duality theorems which refine the classical Stone duality between generalized Boolean algebras and locally compact Boolean spaces. In the first theorem we prove that the category of left-handed skew Boolean algebras whose morphisms are proper skew Boolean algebra homomorphisms is equivalent to the category of étale spaces over locally compact Boolean spaces whose morphisms are étale space cohomomorphisms over continuous proper maps. In the second theorem we prove that the category of left-handed skew Boolean $\cap$-algebras whose morphisms are proper skew Boolean $\cap$-algebra homomorphisms is equivalent to the category of étale spaces with compact clopen equalizers over locally compact Boolean spaces whose morphisms are injective étale space cohomomorphisms over continuous proper maps.

description: We study both numerically and analytically the possibility of using an adiabatic passage control method to construct a Mach-Zehnder interferometer (MZI) for Bose-Einstein condensates (BECs) in the time domain, in exact one-to-one correspondence with the traditional optical MZI that involves two beam splitters and two mirrors. The interference fringes one obtains from such a minimum-disturbance set up clearly demonstrates that, fundamentally, an atom laser is not monochromatic due to interatomic interactions. We also consider how the amount of entanglement in the system correlates to the interference fringes.

description: Quantum technologies use entanglement to outperform classical technologies, and often employ strong cooling and isolation to protect entangled entities from decoherence by random interactions. Here we show that the opposite strategy - promoting random interactions - can help generate and preserve entanglement. We use optical quantum non-demolition measurement to produce entanglement in a hot alkali vapor, in a regime dominated by random spin-exchange collisions. We use Bayesian statistics and spin-squeezing inequalities to show that at least $1.52(4)\times 10^{13}$ of the $5.32(12) \times 10^{13}$ participating atoms enter into singlet-type entangled states, which persist for tens of spin-thermalization times and span thousands of times the nearest-neighbor distance. The results show that high temperatures and strong random interactions need not destroy many-body quantum coherence, that collective measurement can produce very complex entangled states, and that the hot, strongly-interacting media now in use for extreme atomic sensing are well suited for sensing beyond the standard quantum limit.

description: The complexities of the acoustic speech signal pose many significant challenges for listeners. Although perceiving speech begins with auditory processing, investigation of speech perception has progressed mostly independently of study of the auditory system. Nevertheless, a growing body of evidence demonstrates that cross-fertilization between the two areas of research can be productive. We briefly describe research bridging the study of general auditory processing and speech perception, showing that the latter is constrained and influenced by operating characteristics of the auditory system and that our understanding of the processes involved in speech perception is enhanced by study within a more general framework. The disconnect between the two areas of research has stunted the development of a truly interdisciplinary science, but there is an opportunity for great strides in understanding with the development of an integrated field of auditory cognitive science.

description: We investigate the X-ray time lags of a recent ~630ks XMM-Newton observation of PG 1211+143. We find well-correlated variations across the XMM-Newton EPIC bandpass, with the first detection of a hard lag in this source with a mean time delay of up to ~3ks at the lowest frequencies. We find that the energy-dependence of the low-frequency hard lag scales approximately linearly with log(E) when averaged over all orbits, consistent with the propagating fluctuations model. However, we find that the low-frequency lag behaviour becomes more complex on timescales longer than a single orbit, suggestive of additional modes of variability. We also detect a high-frequency soft lag at ~10^{-4}Hz with the magnitude of the delay peaking at <0.8ks, consistent with previous observations, which we discuss in terms of small-scale reverberation.

The distortion of the oxygen sublattice, which was previously ambiguous, is shown to be a chiral structure in which neighbouring oxygen chains have opposite chiralities. A temperature dependent study of the magnetic excitation spectrum, probed by neutron inelastic scattering, is also reported. Changes in the energies and relative intensities of the crystal field transitions provide an insight into the interplay between the static and dynamic Jahn-Teller effects.

Do Regulators Overestimate the Costs of Regulation?

description: It has occasionally been asserted that regulators typically overestimate the costs of the regulations they impose. A number of arguments have been proposed for why this might be the case, with the most widely credited one being that regulators fail sufficiently to appreciate the effects of innovation in reducing regulatory compliance costs. Most existing studies have found that regulators are more likely to over- than to underestimate costs. Moreover, the ratio of ex ante estimates of compliance costs to ex post estimates of the same costs is generally greater than one. In this paper I argue that neither piece of evidence necessarily demonstrates that ex ante estimates are biased. There are several reasons to suppose that the distribution of compliance costs would be skewed, so that the median of the distribution would lie below the mean. It is not surprising, then, that most estimates would prove to be too high. Moreover, we would expect from a simple application of Jensen’s inequality that the expected ratio of ex ante to ex post compliance costs would be greater than one. In this paper I propose a regression-based test of the bias of ex ante compliance cost estimates, and cannot reject the hypothesis that estimates are unbiased. Despite the existence of a number of papers reporting ex ante and ex post compliance cost estimates, it is surprisingly difficult to get a large sample of such comparisons. My most salient finding does not concern the bias of ex ante cost estimates so much as their inaccuracy and the continuing paucity of careful studies.

description: To date, endeavors in nanoscale spintronics are dominated by the use of single-electron or single-spin transistors having at their heart a semiconductor, metallic or molecular quantum dot who's localized states are non-spin-degenerate and can be controlled by an external bias applied via a gate electrode. Adjusting the bias of the gate one can realign those states with respect to the chemical potentials of the leads and thus tailor the spin-polarized transmission properties of the device. Here we show that similar functionality can be achieved in a purely metallic junction comprised of a metallic magnetic chains attached to metallic paramagnetic leads and biased by a gate electrode. Our ab initio calculations of electron transport through mixed Pt-Fe (Fe-Pd and Fe-Rh) atomic chains suspended between Pt (Pd and Rh) electrodes show that spin-polarized confined states of the chain can be shifted by the gate bias causing a change in the relative contributions of majority and minority channels to the nano-contact's conductance. As a result, we observe strong dependence of conductance spin-polarization on the applied gate potential. In some cases the spin-polarization of conductance can even be reversed in sign upon gate potential application, which is a remarkable and promising trait for spintronic applications.

description: Adult speech perception reflects the long-term regularities of the native language, but it is also flexible such that it accommodates and adapts to adverse listening conditions and short-term deviations from native-language norms. The purpose of this article is to examine how the broader neuroscience literature can inform and advance research efforts in understanding the neural basis of flexibility and adaptive plasticity in speech perception. Specifically, we highlight the potential role of learning algorithms that rely on prediction error signals and discuss specific neural structures that are likely to contribute to such learning. To this end, we review behavioral studies, computational accounts, and neuroimaging findings related to adaptive plasticity in speech perception. Already, a few studies have alluded to a potential role of these mechanisms in adaptive plasticity in speech perception. Furthermore, we consider research topics in neuroscience that offer insight into how perception can be adaptively tuned to short-term deviations while balancing the need to maintain stability in the perception of learned long-term regularities. Consideration of the application and limitations of these algorithms in characterizing flexible speech perception under adverse conditions promises to inform theoretical models of speech.

description: We analyse a sample of 33 extensive air showers (EAS) with estimated primary energies above 2\cdot 10^{19} eV and high-quality muon data recorded by the Yakutsk EAS array. We compare, event-by-event, the observed muon density to that expected from CORSIKA simulations for primary protons and iron, using SIBYLL and EPOS hadronic interaction models. The study suggests the presence of two distinct hadronic components, ``light'' and ``heavy''. Simulations with EPOS are in a good agreement with the expected composition in which the light component corresponds to protons and the heavy component to iron-like nuclei. With SYBILL, simulated muon densities for iron primaries are a factor of \sim 1.5 less than those observed for the heavy component, for the same electromagnetic signal. Assuming two-component proton-iron composition and the EPOS model, the fraction of protons with energies E>10^{19} eV is 0.52^{+0.19}_{-0.20} at 95% confidence level.

description: In Anglo-American discourse throughout the colonial era, considerations of the ocean, like considerations of all unbuilt and natural environments, were deeply entwined with religious views. This study puts environmental considerations in conversation with cultural considerations to better understand the image of the sea in the Early American mind. British and British American Protestants in the early modern Atlantic had a nuanced intellectual relationship with the sea, and this relationship reveals priorities and anxieties imbedded in their shared culture. In the early modern era, the oceans were distinctly difficult and adversarial realms, and yet colonial, imperial, and commercial ambitions required ships to frequently traverse the seas. The untamable sea posed exceptional and devastating threats to travelers throughout the early modern era, and language from the era seems to indicate that Anglo-Americans believed that sailors’ immorality was the cause of disasters at sea revealing a belief in a cause-and-effect relationship between morality and the environment. Newspapers, pamphlets, published sermons, legislation, engravings, etchings, fiction and nonfiction narratives function as the key source material for this cultural study. This project not only seeks to understand the meaning of the sea in the colonial era but aims to demonstrate how considerations of the natural world were governed by spirituality throughout colonial era.

description: In this work we show how to construct connectivity kernels induced by the receptive profiles of simple cells of the primary visual cortex (V1). These kernels are directly defined by the shape of such profiles: this provides a metric model for the functional architecture of V1, whose global geometry is determined by the reciprocal interactions between local elements. Our construction adapts to any bank of filters chosen to represent a set of receptive profiles, since it does not require any structure on the parameterization of the family. The connectivity kernel that we define carries a geometrical structure consistent with the well-known properties of long-range horizontal connections in V1, and it is compatible with the perceptual rules synthesized by the concept of association field. These characteristics are still present when the kernel is constructed from a bank of filters arising from an unsupervised learning algorithm.

description: Attempts to use coarse-grained molecular theories to calculate corrections to the random-phase approximation (RPA) for correlations in polymer mixtures have been plagued by an unwanted sensitivity to the value of an arbitrary cutoff length, {\it i.e.}, by an ultraviolet (UV) divergence. We analyze the UV divergence of the inverse structure factor $S^{-1}(k)$ predicted by a `one-loop' approximation similar to that used in several previous studies. We consider both miscible homopolymer blends and disordered diblock copolymer melts. We show, in both cases, that all UV divergent contributions can be absorbed into a renormalization of the values of the phenomenological parameters of a generalized self-consistent field theory (SCFT). This observation allows the construction of a UV convergent theory of corrections to SCFT phenomenology. The UV-divergent one-loop contribution to $S^{-1}(k)$ are shown to be the sum of: (i) a $k$-independent contribution that arises from a renormalization of the effective $χ$ parameter, (ii) a $k$-dependent contribution that arises from a renormalization of monomer statistical segment lengths, (iii) a contribution proportional to $k^{2}$ that arises from a square-gradient contribution to the one-loop fluctuation free energy, and (iv) a $k$-dependent contribution that is inversely proportional to the degree of polymerization, which arises from local perturbations in fluid structure near chain ends and near junctions between blocks in block copolymers.

description: Objective: Analysis of the electroencephalogram (EEG) for epileptic spike and seizure detection or brain-computer interfaces can be severely hampered by the presence of artifacts. The aim of this study is to describe and evaluate a fast automatic algorithm for ongoing correction of artifacts in continuous EEG recordings, which can be applied offline and online. Methods: The automatic algorithm for ongoing correction of artifacts is based on fast blind source separation. It uses a sliding window technique with overlapping epochs and features in the spatial, temporal and frequency domain to detect and correct ocular, cardiac, muscle and powerline artifacts. Results: The approach was validated in an independent evaluation study on publicly available continuous EEG data with 2035 marked artifacts. Validation confirmed that 88% of the artifacts could be removed successfully (ocular: 81%, cardiac: 84%, muscle: 98%, powerline: 100%). It outperformed state-of-the-art algorithms both in terms of artifact reduction rates and computation time. Conclusions: Fast ongoing artifact correction successfully removed a good proportion of artifacts, while preserving most of the EEG signals. Significance: The presented algorithm may be useful for ongoing correction of artifacts, e.g., in online systems for epileptic spike and seizure detection or brain-computer interfaces.

description: Vortex is ubiquitous in nature. However, there is not a consensus on the vortex definition in fluid dynamics. Lack of mathematical definition has caused considerable confusions in visualizing and understanding the coherent vortical structures in turbulence. According to previous study, it is realized that vortex is not the vorticity tube and vorticity should be decomposed into a rotational part which is the vortex vector and a non-rotational part which is the shear. In this paper, several new concepts such as fluid rotation of local point, the direction of fluid rotation axis and the strength of fluid rotation are proposed by investigating the kinematics of fluid element in the 2D and 3D flows. A definition of a new vector quantity called vortex vector is proposed to describe the local fluid rotation. The direction of the vortex vector is defined as the direction of local fluid rotation axis. The velocity components in the plane orthogonal to the vortex vector have zero derivatives along the vortex vector direction. The magnitude of the vortex vector is defined as the rotational part of vorticity in the direction of the vortex vector, which is the twice of the minimum angular velocity of fluid around the point among all azimuth in the plane perpendicular to vortex vector. According to the definition of the vortex vector, vortex is defined as a connected flow region where the magnitude of the vortex vector at each point is larger than zero. The new definition for the vortex vector and vortex follows three principles: 1. Local in quantity, 2. Galilean invariant, 3. Unique. The definitions are carefully checked by DNS and LES examples which clearly show that the new defined vortex vector and vortex can fully represent the complex structures of vortices in turbulence.

description: Nitrogen (N) is a fundamental macronutrient required for the growth and yield of crops. N stabilizers mitigate ammonia volatilization, N leaching, and gaseous losses, while enhancing soil organic matter and nutrient cycling. Different crops, with their own unique root systems, have an influence on levels of soil organic carbon (SOC) and microbial activity. A field trial was carried out to examine the impact of N stabilizers and cropping sequence on microbial biomass nitrogen (MBN), SOC, particulate organic matter N (POM-N), microbial biomass carbon (MBC), total N (TN), particulate organic matter C (POM-C), pH, enzyme activities (urease and β glucosidase), and microbial community in podzolic soils in boreal climate. Experimental treatments were five N treatments [control, Urea, urea split, and three N stabilizers (Agrotain, Super-U, and eNtrench)] and three cropping sequences (corn- corn-corn, corn-wheat-corn, and corn-faba bean-corn). Soil samples were collected after harvesting the crop in 2020 and 2021. Results showed N sources significantly impacted active microbial population, SOC, POM-N, TN, pH, and enzyme activities in 2021. In 2020, N sources had significantly influenced TN and β glucosidase enzyme activity only. Cropping sequence significantly affected MBN, MBC, and POM-C in 2021, however, in 2020, MBN, gram positive bacteria (G⁺), total bacterial phospholipid fatty acids (Σ B-PLFAs) and total phospholipid fatty acids (Σ PLFAs) were significantly affected. In 2021, cropping sequence and N stabilizers interaction significantly influenced G⁺, gram negative bacteria, Σ B-PLFAs and Σ PLFAs. Our results conclude that N stabilizers and cropping sequence improved soil biochemical attributes, microbial activities, and improved soil C pools in podzol soil. However, N stabilizers with different application rates and long-term crop rotation are required to fully understand the effect of these management practices on soil biochemical and microbial processes in podzolic soils under boreal climate.

description: Spoken words exist for mere moments, but from this fleeting acoustic signal, we are able to apprehend considerable information. We can decode the linguistic message of the speaker, as well as information about his or her gender, age, region of origin, identity, and emotional state. As adult listeners, we are so adept at speech perception that the ability seems trivial. However, the ease with which we perceive speech belies the complexity of the perceptual, cognitive, and neural mechanisms involved.

description: We develop a principled way of identifying probability distributions whose independent and identically distributed (iid) realizations are compressible, i.e., can be well-approximated as sparse. We focus on Gaussian random underdetermined linear regression (GULR) problems, where compressibility is known to ensure the success of estimators exploiting sparse regularization. We prove that many distributions revolving around maximum a posteriori (MAP) interpretation of sparse regularized estimators are in fact incompressible, in the limit of large problem sizes. A highlight is the Laplace distribution and $\ell^{1}$ regularized estimators such as the Lasso and Basis Pursuit denoising. To establish this result, we identify non-trivial undersampling regions in GULR where the simple least squares solution almost surely outperforms an oracle sparse solution, when the data is generated from the Laplace distribution. We provide simple rules of thumb to characterize classes of compressible (respectively incompressible) distributions based on their second and fourth moments. Generalized Gaussians and generalized Pareto distributions serve as running examples for concreteness.

description: Taiji program is a space mission aiming to detect gravitational waves in the low frequency band. Taiji-1 is the first technology demonstration satellite of the Taiji Program in Space, with the gravitational reference sensor (GRS) serving as one of its key scientific payloads. For accurate accelerometer measurements, the test-mass center of the GRS must be positioned precisely at the center of gravity of the satellite to avoid measurement disturbances caused by angular acceleration and gradient. Due to installation and measurement errors, fuel consumption during in-flight phase, and other factors, the offset between the test-mass center and the center-of-mass (COM) of the satellite can be significant, degrading the measurement accuracy of the accelerometer. Therefore, the offset needs to be estimated and controlled within the required range by the center-of-mass adjustment mechanism during the satellite's lifetime. In this paper, we present a novel method, the Extended Kalman Filter combined with Rauch-Tung-Striebel Smoother, to estimate the offset, while utilizing the chi-square test to eliminate outliers. Additionally, the nonlinear Least Squares estimation algorithm is employed as a crosscheck to estimate the offset of COM. The two methods are shown to give consistent results, with the offset estimated to be $dx \approx $$-$$0.19$ mm, $dy \approx 0.64$ mm, and $dz \approx $$-$$0.82$ mm. The results indicate a significant improvement on the noise level of GRS after the COM calibration, which will be of great help for the future Taiji program.

Subjects: Chemistry

description: In efforts to develop new catalysts for the partial oxidation of methane to
methanol, studies were focused on developing supported aqueous phase (SAP) catalysts
for this chemistry. The work can be separated into two main projects. First, steps were
taken to prepare an organometallic SAP catalyst. A water-soluble sulfonated Pt diimine
species has been prepared and supported on controlled-pore glass. The compound was
characterized by solid state 13C CP-MAS NMR, and observations were made on the
compounds behavior. This work is carried out in collaboration with research into
homogeneous organometallic catalysts, and progress in this area is dependent on the
development of successful homogeneous catalysts. The second project involves using
platinum/copper salt catalyst for the hydroxylation of alkanes, where dioxygen is the
ultimate oxidant. Several homogeneous reactions were carried out to investigate the
reactivity of this catalyst system in solution. The catalysts were found to successfully
hydroxylate sulfonated alkanes as well as ethane and methane, all with multiple platinum
turnovers. Product characterizations were carried out using 1H NMR and GC/MS.
Efforts were also begun to develop a SAP catalyst with the Pt/Cu system, modeled after
the SAP Pd/Cu Wacker oxidation catalyst.

description: Ramanujan graphs have fascinating properties and history. In this paper we explore a parallel notion of Ramanujan digraphs, collecting relevant results from old and recent papers, and proving some new ones. Almost-normal Ramanujan digraphs are shown to be of special interest, as they are extreme in the sense of an Alon-Boppana theorem, and they have remarkable combinatorial features, such as small diameter, Chernoff bound for sampling, optimal covering time and sharp cutoff. Other topics explored are the connection to Cayley graphs and digraphs, the spectral radius of universal covers, Alon's conjecture for random digraphs, and explicit constructions of almost-normal Ramanujan digraphs.

description: This paper consists of four main divisions. The first of these is a discussion of turbulence in a flowing fluid and of how heat and momentum are transferred thereby. The second is a presentation of the problems met in constructing the apparatus with which to measure the pertinent quantities connected with turbulent transfer. The third is a description of the method of calibration of the measuring instruments. The fourth is a presentation of the experimental results obtained; these results, however, are so limited in quantity that they serve merely as an indication of those to be expected in the future.
SEISMIC PERFORMANCE EVALUATION OF STIFFNESS IRREGULAR RC BUILDINGS DUE TO STORY HEIGHT DIFFERENCE
Creators: name: ABDULHAMID YASSIN
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019
Subjects: soft-story, fragility curves, pushover and limit state capacities

description: In high rise buildings or multi story buildings, soft-story construction is common because of story height
 difference due to architectural consideration. These provide stiffness irregularities on the building
 structures, which reduce the stiffness of the lateral load resisting system and sudden reduction in stiffness
 causes higher stress to be concentrated at the stiffness reduced story columns, which lead the columns to
 be unable to provide adequate resistance during the earth quake.
 Taking into consideration the above points, the structural building frames must be evaluated and designed
 by considering the effect of soft story on seismic performance of the building. The main focus of this
 research is to study the seismic performance of stiffness irregular building due to significant story height
 difference on RC buildings by implementing numerical models on the basis of finite element principles.
 For these two regular buildings G+10 and G+20 is developed to be considered as base case structure, and
 cases that represent irregular structures are defined by modifying vertical distribution stiffness of the base
 case. The stiffness irregularity is created by increasing the height of ground floor and second floor of
 base case 200%. Accordingly, different model cases of RC building are analyzed and designed on ETABS
 2016.2.1 (CSI ETABS 2016, Integrated Building Design Software, Computers and Structures Inc.
 Berkeley). Analysis and design of the proposed building model cases followed the conventional design
 approach as prescribed on the new Ethiopian Buildings Code Standards (ES EN: 2015). The design
 outputs of main structural elements are then used for the numerical model on SeismoStruct [SeismoSoft,
 2016]. Pushover and nonlinear dynamic analyses are carried out for obtaining the response in terms
 fundamental periods, base shear-top displacement, inter-story drift, lateral displacements, and fragility
 curve at different performance levels.
 The result of this research shows the following: the effect of stiffness irregularity on fundamental period
 have more significant contributions as the soft-story number and number of story or building height
 increase, for all cases the Story drifts demands increase in the soft story and decrease in most of the other
 stories and drift of most floors are greater than the allowable drift according to ES EN limit (drν≤0,005h),
 the seismic base shear for stiffness regular building are greater than the stiffness irregular one and finally
 the probability of failure for each limit state capacities of stiffness irregular building model is greater than
 stiffness regular buildings models in all cases.
