description: Loop Gravity provides a microscopic derivation of Black Hole entropy. In this paper, I show that the microstates counted admit a semiclassical description in terms of shapes of a tessellated horizon. The counting of microstates and the computation of the entropy can be done via a mapping to an equivalent statistical mechanical problem: the counting of conformations of a closed polymer chain. This correspondence suggests a number of intriguing relations between the thermodynamics of Black Holes and the physics of polymers.

description: We have studied selected rare earth doped and transition metal doped CeFe2 compounds by examining their structural, magnetic and magneto-thermal properties. With substitution of Ce by 5 and 10% Gd and 10% Ho, the Curie temperature can be tuned to the range of 267-318 K. Localization of Ce 4f electronic state with rare earth substitutions is attributed for the enhancement of Curie temperature. On the other hand, with Ga and Al substitution at the Fe site, system undergoes paramagnetic to ferromagnetic transition and then to an antiferromagnetic phase on cooling. The magnetocaloric effect across the transitions has been studied from both magnetization isotherms and heat capacity data. It is shown that by choosing the appropriate dopant and its concentration, the magnetocaloric effect around room temperature can be tuned.

description: The spin pumping efficiency of lateral standing spin wave modes in a rectangular YIG/Pt sample has been investigated by means of the inverse spin-Hall effect (ISHE). The standing spin waves drive spin pumping, the generation of spin currents from magnetization precession, into the Pt layer which is converted into a detectable voltage due to the ISHE. We discovered that the spin pumping efficiency is significantly higher for lateral standing surface spin waves rather than for volume spin wave modes. The results suggest that the use of higher-mode surface spin waves allows for the fabrication of an efficient spin-current injector.

EVALUATION OF HYDROLOGIAL IMPACTS OF CLIMATE CHANGE ON THE BORKENA CATCHMENT NORTH EASTERN, ETHIOPIA
Creators: name: MANDEFRO AYENACHEW TESFAYE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The  present  study  investigates  the  hydrological  impacts  of  climate  change in  essence,
changes in precipitation and temperature over the Borkena catchment based on a sample of
Coupled Model Inter comparison Project version 5 (CMIP5) downscaled over the Africa
Coordinated Regional climate Downscaling Experiment (CORDEX) domain by a Rossby
Centre regional atmospheric model version 4 (RCA4) output, under RCP 2.6 and RCP 8.5
scenarios. Linear and power transformation bias correction methods was used to improve the
simulation  output  of  RCA4  regional  climate model  with  high  correlation  to the  observed
data. The  bias  corrected  data  were  then  used as  input  to  the  HBV  model  to  simulate  the
corresponding future runoff regime in Borkena catchment. The future projections are made
for two time periods; 2021-2040 and 2081-2100.The result revealed that the maximum and
minimum  temperatures  increase  for  all  the  two  scenarios  in  all  future  time  horizons.
However,  precipitation  does  not  show  a  systematic  increase  or  decrease  in  all future  time
horizons. The model output shows that there may be an annual decrease in runoff depth up to
29.5% for both scenarios in two benchmark periods in the future. There may be a significant
increase in runoff during the Belg season (indications of up to 12.1%) and decrease in runoff
during the Kiremit season (indications of up to 36.1%) and Bega season (indications of up to
36.6%). Based on the results of present analysis, the increase in Belg season runoff would
have paramount importance for small scale irrigation activities practiced by local farmers.
Results from incremental scenario indicate that the impact of climatic variability in Borkena
catchment is higher in precipitation than temperature change. A significant conclusion from
the study is that changes in rainfall have larger effects on runoff.

description: The magnetic microstructure and domain wall distribution of antiferromagnetic $α$-Fe$_2$O$_3$ epitaxial layers is determined by statistical image analyses. Using dichroic spectro-microscopy images, we demonstrate that the domain structure is statistically invariant with thickness and that the antiferromagnetic domain structure of the thin films is inherited from the ferrimagnetic precursor layer one, even after complete transformation into antiferromagnetic $α$-Fe$_2$O$_3$. We show that modifying the magnetic domain structure of the precursor layer is a genuine way to tune the magnetic domain structure and domain walls of the antiferromagnetic layers.

Year: 2015

description: The  success  of  sprinkler  irrigation  system  depends  on  its  actual  performance  at  field
condition. So that, evaluation of the actual  field  performance of sprinkler  irrigation  is  very
important.  Therefore,  this  study  was  intended  to  evaluate  the  irrigation  practice  and  the
infield water application of  Arjo Dedessa  irrigat ion scheme  by  measuring the performance
indicators of the irrigation as it is normally practiced. During the study, 12 field experiments
were  conducted  in  the  period  of  December–February  2014/15  at  two  irrigation  command
area,  to  check  uniformity  of  water  application.  The  soil  physical  characteristics  and  the
gravimetric  water  content  were  determined  in  the  laboratory.  To  estimate  the  crop  water
requirement (CWR) and irrigation water requirement (IWR), the cowpat 8 for windows was
used.  For  the  assessment  of  the  systems  performance,  uniformity  coefficient  (CU),
distribution  uniformity  (DU),  adequacy  of  irrigation  (AD),  application  efficiency  (Ea), )
evaporation  and  wind  drift  losses  (EWD)  were  determined  for  3.5,  4.0,  4.5  and  5.0  bar  of
hydrant  pressure.  The  result  shows  the  mean  application  rates  for  18m  x18m  sprinkler
spacing were 4.95mm/hr and the average  soil  infiltration rates 61mm/hr. The  CU obtained
were 74%, 80%, 85%, and 88% at the respective hydrant pressure of 3.5, 4.0, 4.5 and 5.0bar.
Also distribution uniformity (DU  values obtained  from catch can tests data are 62%, 70%,
76% and 81%at respective hydrant pressure. The values of the system CU and system DU are
very closely to the calculated CU and DU values. The obtained results of the lower quarter
adequacy were  53%, 48%, 52%  and 55%  for respective operating  hydrant pressure of 3.5,
4.0, 4.5 and 5.0bar. The results of potential efficiency of low quarter adequacy (PELQ)  value
vary from 41% to 67%. The average of 0.31%, 0.15%, 0.15% and 0.16% of water  were lost
by evaporation and wind drift during irrigation at the respective hydrant pressure of 3.5, 4.0,
4.5 and 5.0bar.so that, the estate should use the  best combination of the  hydrant operating
pressure and set time to be successful and work as planned.

description: The Spectrometer/Telescope for Imaging X-rays (STIX) is a hard X-ray imaging spectrometer on board the ESA and NASA heliospheric mission Solar Orbiter. STIX has been operational for three years and has observed X-ray emission from ~35,000 solar flares. Throughout its lifetime, Solar Orbiter has been frequently struck by a high flux of energetic particles usually of flare origin, or from coronal mass ejection shocks. These Solar Energetic Particles (SEPs) are detected on board by the purpose-built energetic particle detector instrument suite. During SEP events, the X-ray signal is also contaminated in STIX. This work investigates the effect of these particles on the STIX instrument for two events. The first event occurred during an interplanetary shock crossing and the second event occurred when Solar Orbiter passed through Earth's radiation belts while performing a gravity assist maneuver. The induced spectra consist of tungsten fluorescence emission lines and secondary Bremsstrahlung emission produced by incident particles interacting with spacecraft components. For these two events, we identify > 100 keV electrons as significant contributors to the contamination via Bremsstrahlung emission and tungsten fluorescence.

EVALUATION OF SURFACE WATER RESOURCE AVAILABILITY  UNDER CHANGING CLIMATE CONDITION: CASE STUDY OF  GAUGED CATCHMENT IN JEMMA SUB BASIN
Creators: name: KEDIR GETACHEW
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The sign of climate change and its impact is revealing on different water resource system.
The present study was conducted to understand the climate change impacts on surface water
availability of Robigumer and Beressa River catchments in Jemma sub basin in Abbay Basin.
The Soil and Water Assessment Tool (SWAT) model was applied to study the current (1984-
2008) and future scenarios (2026-2100) runoff magnitude in the catchments and associated
uncertainty with the simulated outputs. The model was calibrated for the period of 1984 to
2000 and validated for the period of 2001-2008. The flow parameters that significantly limit
the runoff in the catchment and the model uncertainty were assessed using SUFI2 in SWAT–
CUP,  Cn2,  Esco,  Canmx  and  Cn2,  Esco  and  Blai,  were  the  most  significant  parameter  in
Beressa and Robigumer catchment respectively. In the end, the future climate change impact
studies  on  water  availability  of  the  catchments  were  done  based  on  the  outputs  of  the
Regional  Climate  Model,  A1B  emission  scenarios.  In  terms  of  hydrological  model
performance the model efficiency magnitude for Beressa and Robigumer catchment is ENS
(0.69, 0.75) and R
2
(0.78, 0.79) during calibration and ENS (0.68, 0.62) and R
2
(0.69, 0.63)
during validation period respectively, which resulted in moderately good model performance
while  simulating  flow  parameters  in  the  catchments.    It  was  also  shown  from  the  model
uncertainty analysis that the percentage of the simulated data within the uncertainty bound is
78  %  for  Beressa  and  73  %  for  Robigumer  River  which  are  good  representation  of  both
catchments.  The evaluation of surface water resource availability flow forecasting was done
for  short  term  (2026-2050),  medium  term  (2051-2075)  and  long  term  (2076-2100)  future
scenarios.  The  annual  flow  volume  in  Beressa  River  increased  by  47.8%  and  54.5%  in
medium and long term future scenarios respectively and decreased by  -61.38% in the short
term.  Robigumer  river  flow  volume  showed  annual  flow  volume  increases  by  13.5%  and
4.7% in the medium and long term period respectively, and decrease by -24.4% for the short
term period. The increase in flow volume will have a paramount importance for agricultura l
activities  practiced  by  local  farmers;  therefore  any  effect  on  this  river  is  reflected  the
decrease in flow will directly affect the ongoing water resource developments planned and
socio economic development on the area.

description: An experiment was conducted during April to July in 2015 at Jawe and Kerekicho Kebeles in
SNNP. The aim was to measure ETc, Kc of Desho grass and oats and vetch fodder crops; and
to evaluate the  WFD  (scheduling tool)  in terms of  biomass yield and water productivity. The
study was among two treatments  with three replicated plots  at  each  of the  study  areas  and
each plot size prepared was 10 m X 10 m. Data collected during the study were: plant height,
soil moisture content of the soil, irrigation depth and  biomass yield. To determine the ETc of
the fodder crops, water balance method was used. Kc of desho grass and oats & vetch fodder
crops  were  computed  from measured ETc and ETo  which was calculated from weather data.
Seasonal ETc of desho grass and oats and vetch was 206 and 186 mm respectively. K
c values
of  desho  grass  at  early,  vegetative,  mid  and  late  stages  were  0.4,  0.71,  0.89,  and  0.72
respectively  whereas  for  oats  &  vetch  was  0.29,  0.89,  1.01,  and  0.71  respectively.  Plant
height  at the mid and late stage for both  fodder  crops; biomass  yield  and irrigation water
productivity were significantly different at  a  significant  level of (p<=0.05) among treatment
plots for  both crops. At the mid and late stages of Desho grass,  the plant height  under  WFD
treatment was higher than the control treatment by 28% and 23% respectively  whereas  the
plant height of  oats and vetch  under  WFD treatment was higher than the  control treatments
at the mid and late season by 23% and 9% respectively. The biomass of desho grass and oats
and vetch at the WFD treatment  was  higher than the control treatment  (local practices)  by
19% and 21% respectively. The irrigation water productivity difference of desho grass and
oats and vetch  under  WFD treatment  was higher  than the control treatment by 13.5  % and
24% respectively.  In conclusion,  WFD  was better to save time, to have better yield, and to
use the water resource effectively and efficiently.

description: Some studies have claimed a universal stellar upper-mass limit of 150 Msun. A factor that is often overlooked is that there might be a difference between the current and initial masses of the most massive stars, as a result of mass loss. We present Monte Carlo mass-loss predictions for very massive stars in the range 40-300 Msun, with large luminosities and Eddington factors Gamma. Using our new dynamical approach, we find an upturn in the mass-loss vs. Gamma dependence, at the point where the winds become optically thick. This coincides with the location where wind efficiency numbers surpass the single-scattering limit of Eta = 1, reaching values up to Eta = 2.5. Our modelling suggests a transition from common O-type winds to Wolf-Rayet characteristics at the point where the winds become optically thick. This transitional behaviour is also revealed with respect to the wind acceleration parameter beta, which starts at values below 1 for the optically thin O-stars, and naturally reaches values as high as 1.5-2 for the optically thick Wolf-Rayet models. An additional finding concerns the transition in spectral morphology of the Of and WN characteristic He II line at 4686 Angstrom. When we express our mass-loss predictions as a function of the electron scattering Gamma_e (=L/M) only, we obtain a mass-loss Gamma dependence that is consistent with a previously reported power-law Mdot propto Gamma^5 (Vink 2006) that was based on our semi-empirical modelling approach. When we express Mdot in terms of both Gamma and stellar mass, we find Mdot propto M^0.8 Gamma^4.8 for our high Gamma models. Finally, we confirm that the Gamma-effect on the mass-loss predictions is much stronger than that of an increased helium abundance, calling for a fundamental revision in the way mass loss is incorporated in evolutionary models of the most massive stars.

GIS BASED SURFACE IRRIGATION POTENTIAL ASSESSMENT OF RIVER CATCHMENTS FOR IRRIGATION DEVELOPMENT IN SEGEN BASIN
Creators: name: ASHENAFI KIFLE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The  study  aims  at  evaluating  physical  suitability  (land  and  water  resource)  for  surface
irrigation  development  using  GIS  techniques.  The  Segen  sub-basin  was  selected  as  a  case
study for this thesis work which is located at the Southern part of the Rift Valley River Basin
covering an area of about 20,517 km
2
.
The evaluation of land in  terms of the suitability classes for surface irrigation was based  on
the  method  as  described  in  FAO  guideline  for  land  evaluation.  The  essence  of  land
evaluation  for  irrigation  is  to  compare  or  match  the  physical  resource  of  soil,  water,
topography  and  others  with  the  irrigation  requirement.  A  land  unit  is  obtained  by  the
overlaying of selected theme layers, which has unique information of land qualities for which
the suitability is based on. The selected theme  layers for this study include soil types, with
their  corresponding  physical  and  chemical  characteristics  that  affect  irrigation  agriculture,
land cover, and slope layer, which is  derived from the Digital Elevation Model of the study
area.  As  its  being  the  most  limiting  factor  for  the  realization  of,  especially  for  surface
irrigation method, the slope layer was used as the base map for the overlaying analysis.
The suitable land identified categorized according to the different climatic zones along  the
Weito and Segen  River in the sub-basin. They are mostly concentrated in the  South  central
and  North Eastern part of the sub-basin.  The 95, 90, 85, and 80 percentage time exceedance
flow  of  the  available  surface  water  in  the  respective  climatic  zones  was  estimated  and  the
area that can be irrigated with this flow was computed using the selected climatic station data
and estimated ETo. Surface irrigation land suitability analysis indicate that 70.9 % of soil and
52.5  %  slope  in  the  study  area  are  in  the  range  of  highly  suitable  to  marginal  suitable  for
surface  irrigation system  whereas the remaining  29.1% (soil) and 47.5% (slope) in the area
are not suitable. In terms of land cover/use, land covered by settlement, degraded shrub land,
forest, wetland, water body and grazing land covering 17.2% of the study area were restricted
from irrigation  development. When these factors were weighted using weighted overlay in
Arc GIS, the potential irrigable land for surface irrigation was reduced to 2.12%.
ADAPTATION TO CLIMATE CHANGE IN UPPER BLUE  NILE BASIN (CASE STUDY OF KOGA IRRIGATION SCHEME)
Creators: name: YESHIWORKAMLAKU ASFAW
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: In this study, impact of climate variability and climate change on Koga irrigation scheme has
been evaluated. In addition, appropriate climate change adaptation options for this irrigation
scheme  have been evaluated through stakeholder  consultation.  A sing le  level  –  stakeholder
consultation was undertaken to prioritize and select the best adaptation options using a Multi
Criteria-  Analysis (MCA) and scenario analysis method. The HBV rainfall runoff model was
used  to  quantify  inflow  to  Koga  reservoir.  The  Water  Evaluation  And  Planning  model
(WEAP)  was  applied  to  evaluate  the  impacts  of  climate  variability  and  change  on  the
reservoir and irrigation scheme. WEAP was set -up for the designed and operational cropping
patterns. High resolution (50km) and  bias corrected outputs of dynamical  downscaled data
from three climate models (GFDL, NORESM and MPI) were used to derive inputs to HBV
and WEAP. The climate scenario is the Representative Concentration Pathways (RCPs) 4.5.
Under  the  designed  cropping  pattern  the  reliability  of  the  Koga  dam  is  98.77%  and  meets
almost 100% of the irrigation demand on annual basis. The demand coverage is small in May
and June which is only 96.33% and 98.46% respectively. The  reliability and coverage of the
Koga  dam  did  not  change  when  the  designed  cropping  pattern  is  replaced  with  the
operational cropping pattern. The NIR  is expected to increase  in all  models due to climate
change. Under the GFDL  model the  largest NIR is seen on the designed crop pattern than
operational cropping pattern. Beside this the reservoir inflow is projected to decrease due to
the reduction of rainfall amount and high amount of net evaporation by GFDL and MIP but,
in NORESM the inflow will not significantly change. According to farmers and experts, the
best options to deal with possible impacts of climate change are to  shift to crops that require
relatively  less amount of water or less  frequent  irrigation, use  short duration crop varieties
and water allocation that takes in to account the development stage of the crops.

description: A matrix model approach to proof of the AGT relation is briefly reviewed. It starts from the substitution of conformal blocks by the Dotsenko-Fateev beta-ensemble averages and Nekrasov functions by a double deformation of the exponentiated Seiberg-Witten prepotential in beta \neq 1 and g_s \neq 0 directions. Establishing the equality of these two quantities is a typical matrix model problem, and it presumably can be ascertained by investigation of integrability properties and developing an associated Harer-Zagier technique for evaluation of the exact resolvent.

description: Evaluation of the  effects of supplementary irrigation on maize crop productivity  under rain fed
agriculture  was  carried  out  at  Arba  Minch  University  Demonstration  site.  The  aim  of  the
research was to study the effect of supplementary irrigation under rain fed for maize crop, in
order  to  provide  necessary  information  in  decision  making  on  irrigation  management.  The
experiment was laid out in a Randomized Complete Block Design (RCBD), and investigated in
the cropping season of the year 2015 GC. There were two main treatments (Rain-fed  (R) and
Rain-fed with supplementary irrigation (SI), and each have three replications. The time of SI was
not  scheduled  to  prove  moisture  stress  free  condition  throughout  the  growing  season.  All
management practices were the same with exception of  water added to (SI). Data analysis was
done for variance and LSD at 5% level of significance. Result showed significant response grain
yield  weight (t/ha), plant height, leaf length, leaf width (m).  Maize average yield under rain-fed
was  2.88t/ha  whereas,  under  10,  25  and  50%ETc  supplementary  irrigation  with  rain  fed  the
grain  yields  were  3.06t/ha,  3.38t/ha  and  3.99t/ha  respectively.  Supplementary  irrigation  was
considered  only  during  the  critical  water  stress  conditions  due  to  inadequacy  of  rainfall  and
when soil moisture was below 20%.    Supplementing rain-fed agricultural production system by
10% of ETc  was  increased  the yield by 6% whereas, supplementing by 25 and 50%ETc during
critical water stress periods was increased the yield by 17 and 39% respectively. This represents
huge potential of supplementary irrigation to improve the productivity of rain-fed agriculture.

description: Soil  erosion,  transport  and  deposition  are  a  cause  for  reservoir sedimentation. Modelling
runoff and sediment yield  of  watershed are  the  most important steps to alleviate reservoir
sedimentation.  This study mainly focused on modeling runoff and sediment yield  of  Kesem
dam  watershed  using SWAT model.  The drainage area of Kesem dam watershed to its outlet
Kesem  dam  site  is  2660km
2
which  contributing  sediment  to  the  reservoir.  The  method
adapted to address this study based on the model sequential applicability.  The model input
data  were  metrological daily data, hydrological and spatial data based on HRUs process by
overlapping  mechanism  and  model  run.  After  model  run,  the  manual  calibrations  were
applied  using  the time series  data  of the study from 1994 to 2010. The model performance
was  checked by statistical model performance indicators such as coefficient of determination
(R
2
),  Nash-Sutcliffe model efficiency (NSE),  and observations standard deviation ratio (RSR)
and Percent bias (PBIAS) and the value was in acceptable range. The model calibrated mean
annual flow at Kesem dam site was 35.14m
3
/s. The mean annual runoff and sediment yield of
the Kesem dam watershed were 543.67mm and 11.43t/ha/yr respectively.  From the Sediment
yield mapping, sub basin 12 and 13 were high sediment yielding sub basins among those 41
sub  basins.  For  these  critical  sub  basins,  Watershed management scenarios were applied.
From the existing baseline condition, the mean annual sediment yield reduced to 8.39t/ha/yr
due to 5m filter strip width, 5.61t/ha/yr due to 10m filter strip width, 8.76t/ha/yr due to grass
waterway  and  7.55t/ha/yr due to terracing. Generally, filter strip 10m significant ly reduce
sediment yield.

description: Even if new physics beyond the Standard Model (SM) indeed exists, the energy scale of new physics might be beyond the reach at the Large Hadron Collider (LHC) and the LHC could find only the Higgs boson but nothing else. This is the so-called "nightmare scenario". On the other hand, the existence of the dark matter has been established from various observations. One of the promising candidates for thermal relic dark matter is a stable and electric charge-neutral Weakly Interacting Massive Particle (WIMP) with the mass below the TeV scale. In the nightmare scenario, we introduce a WIMP dark matter singlet under the SM gauge group, which only couples to the Higgs doublet at the lowest order, and investigate a possibility that such WIMP dark matter can be a clue to overcome the nightmare scenario via various phenomenological tests such as the dark matter relic abundance, the direct detection experiments for the dark matter particle, and the production of the dark matter particle at the LHC.

EVALUATION OF IMPACT OF CLIMATE CHANGE ON WATER RESOURCE  AVAILABILITY ON ABAYA - CHAMO BASIN (THE CASE OF KULFO CATCHMENT)
Creators: name: TADELECH ALEM
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Nowadays  the  sign  of  climate  change  and  its  impact  is  revealing  on  different  natural  and
man-made systems, in one or other ways. Accordingly, this impact is significant on the water
resource system. This study mainly deals with evaluation of the climate change impact on the
Kulfo catchmenet which is found in Rift valley. Statistical down Scaling Method (SDSM)
was applied in order to downscale the climate variables at catchment level. SDSM was also
used to downscale the present and future monthly precipitation and temperature from the UK
Hadley center (HadCM3). Two future emission scenarios, A2 and B2 were considered for the
three different periods (2030s, 2060s and 2080-2099). Downscaling was done to obtain finer
resolution  output  from  the  GCM,  so  that  it  matches  with  the  Kulfo  catchment  scale.  The
downscaled future climate showed that the mean daily minimum and maximum temperatures
increase  by  up  to  1.65/2.0  (2030s),  1.66/3.0  (2060s)  and  1.66/3.6  (2080-2099)  and  annual
precipitation also expected to increase up to  11%  and 9%  compared to base period for A2
and  B2  scenarios.  The  output  of  downscaled  data  provided  input  rainfall  and  temperature
data  for  the  HEC-HMS  model  to  estimate  flow.  A  hydrological  model,  HEC-HMS  was
utilized to simulate the flow. The performance of the model was assessed through calibration
and validation process and resulted R
2
=0.88 and NSE=0.87 during calibration and R
2=
0.9,
NSE =0.866 during validation.  The impact of climate change may also cause  an  increase in
monthly mean flow up to 122% in the 2050s under A2 scenario and increase up to 100% in
the  2090s  under  B2  scenario.  Seasonal  mean  flow  may  show  increase  up  to  106.6%  Bega
(JFD) and 42.8% Belg (SON) in season for 2050s and 2090s time periods respectively under
B2 scenario. The increasing of seasonal mean flow in Bega (JFD) has its own contribution
for occurrence of flooding in Kulfo Catchment. It is observed that there may be a net annual
increase in mean annual flow volume in Kulfo River due to climate change.

description: It is well known that observing CP violation in many-body decays could provide strong evidence for physics beyond the Standard Model. Many searches have been carried out; however, no 5sigma evidence for CP violation has yet been found in these types of decays. A novel model-independent method for observing CP violation in many-body decays is presented in this paper. It is shown that the sensitivity of this method is significantly larger than those used to-date.

description: Superconductivity, magnetic order, and quadrupolar order have been investigated in the filled skutterudite system Pr$_{1-x}$Nd$_{x}$Os$_4$Sb$_{12}$ as a function of composition $x$ in magnetic fields up to 9 tesla and at temperatures between 50 mK and 10 K. Electrical resistivity measurements indicate that the high field ordered phase (HFOP), which has been identified with antiferroquadruoplar order, persists to $x$ $\sim$ 0.5. The superconducting critical temperature $T_c$ of PrOs$_4$Sb$_{12}$ is depressed linearly with Nd concentration to $x$ $\sim$ 0.55, whereas the Curie temperature $T_{FM}$ of NdOs$_4$Sb$_{12}$ is depressed linearly with Pr composition to ($1-x$) $\sim$ 0.45. In the superconducting region, the upper critical field $H_{c2}(x,0)$ is depressed quadratically with $x$ in the range 0 $

Conditions for growth and extinction in matrix models with environmental stochasticity
Creators: name: Sanz, Luis
Publisher: name: arXiv
Year: 2024
Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: In this kind of model, the main characteristic that determines population viability in the long term is the stochastic growth rate (SGR) denoted $λ_S$. When $λ_S$ is larger than one, the population grows exponentially with probability one and when it is smaller than one, the population goes extinct with probability one. However, even in very simple situations it is not possible to calculate the SGR analytically. The literature offers some approximations for the case in which environmental variability is low, and there are also some lower and upper bounds, but there is no study of the practical situations in which they would be tight. Some new bounds for the SGR are built and the conditions under which each bound works best are analyzed. These bounds are used to give some necessary and some sufficient conditions for population explosion and extinction that are easy to check in practice. The general results are applied to several cases, amongst them a population structured as juveniles and adults living in an environment switching randomly between "rich" and "poor".
