ANALYSIS OF CLIMATE VARIABILITY AND THE ASSOCIATED  METEOROLOGICAL DROUGHT IN THE SOUTHERN PART OF  ETHIOPIAN RIFT VALLEY
Creators: name: TADEWOS SEYOUM DELKASO
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Nowadays,  climate  variability  and  its  impact  is  the  main  concern  put  at  the  top  of  global
agenda.  Climate  variability  in  Ethiopia  where  agriculture  is  the  dominant  sector  of  the
economy  is  also  increasingly  attracting  attention.  A  large  percentage  of  the  population  is
already  vulnerable  to  a  range  of  natural  ha zards  with  increasing  climate  variability  and
climate  change  expected  to  aggravate  the  situation  further  by  causing  more  frequent  and
intense  droughts.  In  this  study,  climate  variability  was  assessed   using  different  types  of
parameters  such  as  coefficient  of  Variation(CV),  rainfall  anomaly  index(RAI),  Gaussian
index(GI) and other variability causing agents such as onset date of rainfall in season and ElNino seasonal impacts. The related meteorological drought occurrence in terms of severity,
duration  and  frequency  was  also  analyzed.  The  SPI  calculator  software  was  applied  to
compute drought in the study area. The study area practiced drought of different severity in
different  temporal  and  spatial  scales  other  than  common  drought  years  that  occurred
throughout the area. In order to analyze future climate variability and related drought events,
GCM derived scenarios (HadCM3 A2a & B2a SRES emission scenarios) were used for the
climate projection. The future climatic elements such as rainfall, maximum temperatu re and
minimum temperature are generated by SDSM software.  There is high climate variability in
the smaller rainy  season and  mostly  moderate to high climate variabi lity  in the  main rainy
season.  There will be low to moderate climate variability for both projection scenarios. The
future climatic condition and the related drought were analyzed  from the projected climate
variables.  There  is  a  likely  increasing  maximum  and  minimum  temperature  for  both
HadCM3 A2a & B2a SRES emission scenarios. Precipitation also  will increase in the study
area  with  small  decrease  at  Mirab  station  in2020s  and  slowly  start  to  increase.  Drought
resulting  from climate variability  is  likely to occur. Areas such as Mirab Abaya and  Alaba
station with smaller projected rainfall will be highly sensitive to dry climatic condition and
the  related  drought.  To  reduce  the  impact  of  climate  variability  and  the  related  drought,  some
measures  such  as  high  awareness  on  climate  variability  for  food  production,  attention  to  early
warnings and wise use of available water in the drought prone areas are recommended.

description: Climate  change  is  a  topic  of  discussion  worldwide  including  Ethiopia.  The  present  study
assessed  the  possible  impacts  of  climate  change  on  runoff  in  the  upper  Birbir  sub  basin
which  is  located  in  8°48′17′′ and  9°22′19′′ N  and  34°C49′39′′and  35°C37′27′′E;  western
Ethiopia.  CORDEX-Africa  data  outputs  of  HadGEM2-ES  for upper Birbir sub basin were
selected under representative concentration pathways (RCP4.5& RCP8.5) scenario to make
future  projections  in  two  time  frames:  mid-term  (2041-2070)  and  long-term (2071-2100).
After assessment of data quality;  Bias,  Coefficient of Variation  and correlation were used to
evaluate  the  systematic  error  of  rainfall  amount,  degree  of  rainfall  variability  and  the
relationship  of  model  outputs  and  observed datasets  in addition to  graphical plots.  Trend
detection  was  evaluated  by  Mann-Kendall  trend  test  and  sen’s  estimators.  Hargreaves
method was used to estimate current and future evapotranspiration. HBV model was selected
to  simulate  future  stream  flow  for  the  projected  climate  variables .  Coefficient  of
determination (R
2
), Nash-Sutcliffe Efficiency (NSE), Relative Volume Error (RVE) and  Root
mean square error observation standard deviation ratio (RSR)  were statistical tools used for
performance  evaluation  of  rainfall-runoff  model (HBV) with a result of 0.82, 0.81, 5.70%
and 0.11during calibration period.    The  observed annual rainfall shows upward trend except
for  Yubdo  station, and  temperature  shows warming trend.  Future projections of runoff will
be expected to decrease in winter and spring while increase in summer  and  autumn, mainly
followed the rainfall  projected pattern.    In mid-term, the annual average runoff projection
will be expected to decrease by 2.05% and 1.35% under RCP4.5 and RCP8.5, respectively.
In long-term, it will be expected to decrease by about 0.03% a nd 2.0% under RCP4.5 and
RCP8.5 over upper Birbir sub basin

description: Topological quantum phases of quantum materials are defined through their topological invariants. These topological invariants are quantities that characterize the global geometrical properties of the quantum wave functions and thus are immune to local noise. Here, we present a strategy to measure topological invariants on quantum computers. We show that our strategy can be easily integrated with the variational quantum eigensolver (VQE) so that the topological properties of generic quantum many-body states can be characterized on current quantum hardware. We demonstrate the robust nature of the method by measuring topological invariants for both non-interacting and interacting models, and map out interacting quantum phase diagrams on quantum simulators and IBM quantum hardware.

description: An \textit{ideal} of $N$-tuples of operators is a class invariant with respect to unitary equivalence which contains direct sums of arbitrary collections of its members as well as their (reduced) parts. New decomposition theorems (with respect to ideals) for $N$-tuples of closed densely defined linear operators acting in a common (arbitrary) Hilbert space are presented. Algebraic and order (with respect to containment) properties of the class $CDD_N$ of all unitary equivalence classes of such $N$-tuples are established and certain ideals in $CDD_N$ are distinguished. It is proved that infinite operations in $CDD_N$ may be reconstructed from the direct sum operation of a pair. \textit{Prime decomposition} in $CDD_N$ is proposed and its (in a sense) uniqueness is established. The issue of classification of ideals in $CDD_N$ (up to isomorphism) is discussed. A model for $CDD_N$ is described and its concrete realization is presented. A new partial order of $N$-tuples of operators is introduced and its fundamental properties are established. Extremal importance of unitary disjointness of $N$-tuples and the way how it `tidies up' the structure of $CDD_N$ are emphasized.

description: The August, 2006 flood event was one of the most significant and damaging natural
disasters ever hit Diredawa. The total damages to public and private property were
estimated 94,327,416.21Birr, 256 people died,244 people missing, crops on 256.7 ha of
land were destroyed, rural water supply schemes were damaged in 17 rural kebeles,
irrigation schemes were damaged and thousands of people evacuated and sheltered in
temporary camps and fed for months there.
This emphasizes the need for more reliable predictions of floods and their causes. This
study focuses on the investigation of the cause and magnitude of flood in Diredawa area.
Hydro-meteorological, topographic, land use and soil data of the study area have been
used for the study. Various time scale rainfall data (monthly, daily or less than daily)
have been examined to establish the causes of the flood. The aerial coverage, duration
and intensity of the rainfall data were used. Accordingly the result revealed that the
extreme daily rainfall which occurred on August 6, 2006 was found to be the cause of the
flooding. Rational method was used to calculate peak discharge. This flood has produced
/sec which flooded the densely settled suburb of
Diredawa town.
The destruction caused by this flood reveals the high cost imposed upon life and property
by floods, and thus highlights the importance of preparing for such occurrences. It is
possible to predict and contain a flood to a reasonable extent. The paper discuses some of
the details of the flood, the precipitation event caused the flood and the mitigation
measures.
The rational method predicts peak runoff rates from data on rainfall intensity and
drainage basin characteristics. In
application of the rational method, design values of time
of concentration and runoff coefficient was estimated.
IDF curve was developed to find the intensity used in the rational formula .The predicted
frequensy is determined by finding the intersection of the lines defined by the measured
intensity and storm duration .The basic data used for intensity- duration-frequensy
analysis of point rainfall consists of the largest events of each year. The point rainfall

estimate obtained from IDF curves were adjusted for large areas because the point
estimates represent extreme values.

The rms deviation with respect to 2149 measured nuclear masses is reduced to 0.441 MeV. The shell corrections, the deformations of nuclei, the neutron and proton drip lines, and the shell gaps are also investigated to test the model. The rms deviation of alpha-decay energies of 46 super-heavy nuclei is reduced to 0.263 MeV. The central position of the super-heavy island could lie around N=176~178 and Z=116~120 according to the shell corrections of nuclei.

Quasilinear Schrödinger equations: ground state and infinitely many normalized solutions

Publisher: name: arXiv
Year: 2021
Subjects: subject: Analysis of PDEs (math.AP)

description: In the present paper, we study the normalized solutions for the following quasilinear Schrödinger equations: $$-Δu-uΔu^2+λu=|u|^{p-2}u \quad \text{in}~\mathbb R^N,$$ with prescribed mass $$\int_{\mathbb R^N} u^2=a^2.$$ We first consider the mass-supercritical case $p>4+\frac{4}{N}$, which has not been studied before. By using a perturbation method, we succeed to prove the existence of ground state normalized solutions, and by applying the index theory, we obtain the existence of infinitely many normalized solutions. Then we turn to study the mass-critical case, i.e., $p=4+\frac{4}{N}$, and obtain some new existence results. Moreover, we also observe a concentration behavior of the ground state solutions.

description: The past decade has seen an increased interest in human activity recognition based on sensor data. Most often, the sensor data come unannotated, creating the need for fast labelling methods. For assessing the quality of the labelling, an appropriate performance measure has to be chosen. Our main contribution is a novel post-processing method for activity recognition. It improves the accuracy of the classification methods by correcting for unrealistic short activities in the estimate. We also propose a new performance measure, the Locally Time-Shifted Measure (LTS measure), which addresses uncertainty in the times of state changes. The effectiveness of the post-processing method is evaluated, using the novel LTS measure, on the basis of a simulated dataset and a real application on sensor data from football. The simulation study is also used to discuss the choice of the parameters of the post-processing method and the LTS measure.

Supergranule aggregation: a Prandtl number-independent feature of constant heat flux-driven convection flows

description: Supergranule aggregation, i.e., the gradual aggregation of convection cells to horizontally extended networks of flow structures, is a unique feature of constant heat flux-driven turbulent convection. In the present study, we address the question if this mechanism of self-organisation of the flow is present for any fluid. Therefore, we analyse three-dimensional Rayleigh-Bénard convection at a fixed Rayleigh number $\textrm{Ra} \approx 2.0 \times 10^{5}$ across $4$ orders of Prandtl numbers $\Pr \in \left[ 10^{-2}, 10^{2} \right]$ by means of direct numerical simulations in horizontally extended periodic domains with aspect ratio $Γ= 60$. Our study confirms the omnipresence of the mechanism of supergranule aggregation for the entire range of investigated fluids. Moreover, we analyse the effect of $\Pr$ on the global heat and momentum transport, and clarify the role of a potential stable stratification in the bulk of the fluid layer. The ubiquity of the investigated mechanism of flow self-organisation underlines its relevance for pattern formation in geophysical and astrophysical convection flows, the latter of which are often driven by prescribed heat fluxes.

description: We report on suspended single-layer graphene deposition by a transfer-printing approach based on polydimethylsiloxane stamps. The transfer printing method allows the exfoliation of graphite flakes from a bulk graphite sample and their residue-free deposition on a silicon dioxide substrate. This deposition system creates a blistered graphene surface due to strain induced by the transfer process itself. Single-layer-graphene deposition and its "blistering" on the substrate are demonstrated by a combination of Raman spectroscopy, scanning electron microscopy and atomic-force microscopy measurements. Finally, we demonstrate that blister-like suspended graphene are self-supporting single-layer structures and can be flattened by employing a spatially-resolved direct-lithography technique based on electron-beam induced etching.

description: Recent observations of resolved cold debris disks at tens of au have revealed that gaps could be a common feature in these Kuiper belt analogues. Such gaps could be evidence for the presence of planets within the gaps or closer-in near the edges of the disk. We present SPHERE observations of HD 92945 and HD 107146, two systems with detected gaps. We constrained the mass of possible companions responsible for the gap to 1-2 M Jup for planets located inside the gap and to less than 5 M Jup for separations down to 20 au from the host star. These limits allow us to exclude some of the possible configurations of the planetary systems proposed to explain the shape of the disks around these two stars. In order to put tighter limits on the mass at very short separations from the star, where direct imaging data are less effective, we also combined our data with astrometric measurements from Hipparcos and Gaia and radial velocity measurements. We were able to limit the separation and the mass of the companion potentially responsible for the proper motion anomaly of HD 107146 to values of 2-7 au and 2-5 M Jup , respectively.

description: Microcapsules are commonly used in applications ranging from therapeutics to personal care products due to their ability to deliver encapsulated species through their porous shells. Here, we demonstrate a simple and scalable approach to fabricate microcapsules with porous shells by interfacial complexation of cellulose nanofibrils and oleylamine, and investigate the rheological properties of suspensions of the resulting microcapsules. The suspensions of neat capsules are viscous liquids whose viscosity increases with volume fraction according to a modified Kreiger-Dougherty relation with a maximum packing fraction of 0.73 and an intrinsic viscosity of 4. When polyacrylic acid (PAA) is added to the internal phase of the microcapsule, however, the suspensions become elastic and display yield stresses with power-law dependencies on capsule volume fraction and PAA concentration. The elasticity appears to originate from associative interactions between microcapsules induced by PAA that resides within the microcapsule shells. These results demonstrate that it is possible to tune the rheological properties of microcapsule suspensions by changing only the composition of the internal phase, thereby providing a novel method to tailor complex fluid rheology.

description: Статья посвящена анализу последствий устранения термина «подведомственность» из процессуального законодательства. Автором отмечается, что в результате трансформации института подведомственности в институт подсудности произошло расширение последнего. Поскольку обновленный институт подсудности теперь выполняет две различные функции, авторы предлагают подразделить подсудность на два вида: внешнюю подсудность (разграничивающую компетенцию между государственными и негосударственными судебными органами) и внутреннюю подсудность (разграничивающую компетенцию внутри системы судов общей юрисдикции).

description: We investigate the first-passage properties of bursty random walks on a finite one-dimensional interval of length L, in which unit-length steps to the left occur with probability close to one, while steps of length b to the right -- "bursts" -- occur with small probability. This stochastic process provides a crude description of the early stages of virus spread in an organism after exposure. The interesting regime arises when b is of the order of but less than 1, where the conditional exit time to reach L, corresponding to an infected state, has a non-monotonic dependence on initial position. Both the exit probability and the infection time exhibit complex dependences on the initial condition due to the interplay between the burst length and interval length.

description: We investigate a thermo-resistive instability in the outer crusts of magnetars wherein a perturbation in temperature increases ohmic heating. We show that magnetars of characteristic age τ_{age} ~ 10^4 yr are unstable over timescales as short as days if strong current sheets are present in the outer crust. This instability could play an important role in the thermal and magnetic field evolution of magnetars, and may be related to bursting activity in magnetars.

description: We use learning data of an e-assessment platform for an introductory mathematical statistics course to predict the probability of passing the final exam for each student. Subsequently, we send warning emails to students with a low predicted probability to pass the exam. We detect a positive but imprecisely estimated effect of this treatment, suggesting the effectiveness of such interventions only when administered more intensively.

description: We provide statistical analysis methods for samples of curves when the image but not the parametrisation of the curves is of interest. A parametrisation invariant analysis can be based on the elastic distance of the curves modulo warping, but existing methods have limitations in common realistic settings where curves are irregularly and potentially sparsely observed. We provide methods and algorithms to approximate the elastic distance for such curves via interpreting them as polygons. Moreover, we propose to use spline curves for modelling smooth or polygonal Fréchet means of open or closed curves with respect to the elastic distance and show identifiability of the spline model modulo warping. We illustrate the use of our methods for elastic mean and distance computation by application to two datasets. The first application clusters sparsely sampled GPS tracks based on the elastic distance and computes smooth means for each cluster to find new paths on Tempelhof field in Berlin. The second classifies irregularly sampled handwritten spirals of Parkinson's patients and controls based on the elastic distance to a mean spiral curve computed using our approach. All developed methods are implemented in the \texttt{R}-package \texttt{elasdics} and evaluated in simulations.

description: Recent advances in deep learning architectures for sequence modeling have not fully transferred to tasks handling time-series from electronic health records. In particular, in problems related to the Intensive Care Unit (ICU), the state-of-the-art remains to tackle sequence classification in a tabular manner with tree-based methods. Recent findings in deep learning for tabular data are now surpassing these classical methods by better handling the severe heterogeneity of data input features. Given the similar level of feature heterogeneity exhibited by ICU time-series and motivated by these findings, we explore these novel methods' impact on clinical sequence modeling tasks. By jointly using such advances in deep learning for tabular data, our primary objective is to underscore the importance of step-wise embeddings in time-series modeling, which remain unexplored in machine learning methods for clinical data. On a variety of clinically relevant tasks from two large-scale ICU datasets, MIMIC-III and HiRID, our work provides an exhaustive analysis of state-of-the-art methods for tabular time-series as time-step embedding models, showing overall performance improvement. In particular, we evidence the importance of feature grouping in clinical time-series, with significant performance gains when considering features within predefined semantic groups in the step-wise embedding module.

description: Localized point sources (monopoles) in an acoustical domain are implemented to a three dimensional non-singular Helmholtz boundary element method in the frequency domain. It allows for the straightforward use of higher order surface elements on the boundaries of the problem. It will been shown that the effect of the monopole sources ends up on the right hand side of the resulting matrix system. Some carefully selected examples are studied, such as point sources near and within a concentric spherical core-shell scatterer (with theoretical verification), near a curved focusing surface and near a multi-scale and multi-domain acoustic lens.

description: Observations of gravitational waves from compact binary mergers have enabled unique tests of general relativity in the dynamical and non-linear regimes. One of the most important such tests are constraints on the post-Newtonian (PN) corrections to the phase of the gravitational wave signal. The values of these PN coefficients can be calculated within standard general relativity, and these values are different in many alternate theories of gravity. It is clearly of great interest to constrain these deviations based on gravitational wave observations. In the majority of such tests which have been carried out, and which yield by far the most stringent constraints, it is common to vary these PN coefficients individually. While this might in principle be useful for detecting certain deviations from standard general relativity, it is a serious limitation. For example, we would expect alternate theories of gravity to generically have additional parameters. The corrections to the PN coefficients would be expected to depend on these additional non-GR parameters whence, we expect that the various PN coefficients to be highly correlated. We present an alternate analysis here using data from the binary neutron star coalescence GW170817. Our analysis uses an appropriate linear combination of non-GR parameters that represent absolute deviations from the corresponding post-Newtonian inspiral coefficients in the TaylorF2 approximant phase. These combinations represent uncorrelated non-GR parameters which correspond to principal directions of their covariance matrix in the parameter subspace. Our results illustrate good agreement with GR. In particular, the integral non-GR phase is $Ψ_{\mbox{non-GR}} = (0.447\pm253)\times10^{-1}$ and the deviation from GR percentile is $p^{\mbox{Dev-GR}}_{n}=25.85\%$.

title: DEPRECATED: ANALYSIS OF THE IMPACT OF EAST EUROPEAN CHANGE UPON EUROPEAN COMMUNITY AND EAST EUROPEAN LINER SHIPPING
Creators: name: LEDGER, GILLIAN DEBORAH
Publisher: name: University of Plymouth
Year: 1995

description: In its attempt to analyse the impact of East European change upon the European Community and East European liner shipping industries this thesis covers an extensive range of highly topical subject areas. The wide range of non uniform information gleaned from the research and the question of spurious objectivity form the main arguments behind the use of qualitative rather than quantitative assessment throughout. The diverse study area also necessitated a narrowing to the case of Polish Ocean Lines' North Atlantic operations to enable a meaningful analysis to be carried out. The early part of the thesis examines the background to the East European situation before moving on to identify the main issues that directly affect Polish shipping, through the use of a Contextual model. Using the information gained here a newly developed Contextual Matrix Model then enables the main issues to be extracted. These issues indicate that the changes affecting Polish Ocean Lines require an exercise in repositioning. To assess this fully a framework approach is developed to determine Polish Ocean Lines' position for 1988 and 1992. A further framework is then created for the European Community competitors' 1992 position, in order that a positional comparison can be carried out with Polish Ocean Lines. The results of the comparison indicate that repositioning is taking place at Polish Ocean Lines as a direct reaction to the changes occurring throughout East Europe. The discussion concludes that this is a dynamic, volatile and topical area which raises a number of points of possible interest for further research.

description: In science, collaboration is sometimes understood as synonymous with co‐authorship. However, it also can be measured through the exchange of information and materials. In agriculture, potato late blight is still a challenge to the breeding
programs. Accessing different materials, which can be used as sources of resistance, is the key to successful disease control.
This article maps the germplasm exchanges carried out by potato breeding in the world as a way to measure collaboration
between countries. Cultivars of potato resistant to late blight were selected based on a European database and some
countries stood out from others. This was mainly the case of Germany and the Netherlands. Most of the countries have
greater links with themselves than with other countries, with reinforces the idea that national breeding programs work
more closely within their own country than with other countries. The hegemony of some countries, the prioritization of
national research and the high costs of developing a resistant cultivar can be obstacles to greater collaboration.

description: Abstract. The aim: to study the features of perforative gastroduodenal ulcer (PGDU) in cancer patients. Materials and methods: a retrospective study of the postoperative results of surgical treat-ment of PGDU in 45 patients with malignant tumors in VRCOD. Comorbidity was assessed on the ba-sis of Charlson-Deyo scale. Paired, multiple linear and binary logistic regression was used to predict the duration and outcome of treatment. Results: 45 patients were included into the analysis: 25 (55.6 %) men and 20 (44.4 %) women. The median age was 54 years (Q1-Q3 = 46-67). Ulcer history is not-ed in 25 (55.6 %) observations. Combined complications were met in 4 (8.9 %) cases. The most com-mon localization of PGDU was the front wall of the bulb of the duodenum - 17 (37.8 %). The pres-ence of cancer caused the minimum Charlson-Deyo index 2, and in 13 (28.9 %) cases of metastatic cancer - 6. Suturing of the ulcer prevailed in 36 cases (80 %). In other observations we performed: stomach resection - 5 (11.1 %), vagotomy with pyloroplasty - 1 (2.2 %), suturing of the ulcer from the minilaparotomy - 2 (4.5 %), laparoscopic suturing of the ulcer - 1 (2.2 %). The median duration of the operation at PGD was 80 (Q1-Q3=70-95) minutes. The duration of the postoperative period was on average 10 days (IQR9-14 days). The mortality rate was 15.6 % (7/45). Patients with Charlson-Deyo comorbidity index above 3 had a higher risk of postoperative complications (p=0,005) and death (p=0,039). During the univariate analysis general surgical and comorbidity factors affecting postopera-tive mortality were revealed: age (p=0,01), perforation duration of more than 24 hours (p<0,001), Bo-ey index 2-3 (p=0,005), Mannheim peritonitis index more than 29 (p<0,001), the number of chemo-therapy courses performed (p=0,006) and the Charlson-Deyo index more than 3 (p=0,05).  In multi-variate analysis - age (p=0,028) and the number of chemotherapy courses conducted (p=0,008).

description: We present here the final results of the first spectropolarimetric survey of a small sample of active M dwarfs, aimed at providing observational constraints on dynamo action on both sides of the full-convection threshold (spectral type M4). Our two previous studies (Donati et al. 2008b; Morin et al. 2008b) were focused on early and mid M dwarfs. The present paper examines 11 fully convective late M dwarfs (spectral types M5-M8). Tomographic imaging techniques were applied to time-series of circularly polarised profiles of 6 stars, in order to infer their large-scale magnetic topologies. For 3 other stars we could not produce such magnetic maps, because of low variability of the Stokes V signatures, but were able to derive some properties of the magnetic fields. We find 2 distinct categories of magnetic topologies: on the one hand strong axisymmetric dipolar fields (similar to mid M dwarfs), and on the other hand weak fields generally featuring a significant non-axisymmetric component, and sometimes a significant toroidal one. Comparison with unsigned magnetic fluxes demonstrates that the second category of magnetic fields shows less organization (less energy in the large scales), similarly to partly convective early M dwarfs. Stars in both categories have similar stellar parameters, our data do not evidence a separation between these 2 categories in the mass-rotation plane. We also report marginal detection of a large-scale magnetic field on the M8 star VB 10 featuring a significant toroidal axisymmetric component, whereas no field is detectable on VB 8 (M7).
