description: Ethiopia  has  been  practicing  resettlement  since  the  Imperial  era.  The  current  resettlement
scheme  has  some  peculiarities  from  the  former  regimes  as  it  is  voluntarism  based,  intra
regional  and  secures  resettlers’  right.  Environmental  impacts  induced  by  resettlers  at
Gumgumuta  were  the  focus  of  this  study.  The  main  objective  of  the  study  was  to  assess
environmental  impacts  induced  by  resettlers.  To  attain  this,  pertinent  data  were  gathered
employing  interview,  questionnaire,  FGD  and  field  observation.  80  sample  respondents  were
selected  by  systematic  sampling  technique  from  the  homogenous  population.  Mixed  research
design  specifically  Concurrent  Triangulation  Strategy  was  used  as  it  better  helped  to
understand the problem. For analysis, SPSS version 20  for quantitative data  both  descriptive
and inferential  statistics  as well as  verbal descriptions  for  qualitative  data  were employed. The
findings  indicated  as  human  resettlements  induce  adverse  environmental  impacts  at
destinations  namely  deforestation,  wildlife  threats  and  quantity  declines  of  water  bodies.
Concerning deforestation, only 4.77%  of  the  area  (23 ha  of forest cover)  was  remained  from
72.56%  of  its  area  (349.85  ha  of  forest  cover)  before  the  resettlement  as  much  was  lost  by
conversion to  homesteads  (16.1ha),  farmlands (302.5 ha),  and  institutional occupations (8.25
ha)  with increased extent while exploiting as source of fuel wood, construction materials and by
road  construction.  Most  wild  lives  existed  before  the  relocation  were  hardly  available  at  the
area being  exposed to various threats like complete disappearance, forced habitat change, loss
of habitat and feeding sources as well as conflicts  with humans and  each other.  Rivers  of the
area were examined  with  varied quantity problems (seasonal  volume fluctuation, early drying
and  disappearance  of  impressive  waterfalls).  Possible  remedial  interventions  quoted  as
“EARTH for environment”  were recommended to  sustain the risky environmental components
in which each bold letter has its own implication.

description: This article explains recent changes in the negotiation dynamics concerning EU asylum policies, the policy failure in the Common European Asylum System and the deadlock in its post-2016 reform. Combining the Core State Power framework with the literature on punctuated equilibria and bounded rationality, it argues that EU asylum policies have important redistributive implications. In earlier phases, these were concealed by a regulatory policymaking approach which depoliticized EU legislation in that area. The 2015 asylum crisis demonstrated that this approach failed to produce the expected integration and entailed an even unfairer distribution of asylum-seekers, hence leading to information updating among Member States. Together with the ascent of right-wing populism in many Member States, this has fundamentally changed the negotiation dynamics from a situation with a few dominant Member States to a highly politicized environment in which previously passive Member States acted either as promoters or as blockers, thus producing deadlock.

description: In this paper, we will use $δ\mathcal{N}$-formalism to calculate the primordial curvature perturbation for the curvaton model with a Lagrange multiplier field. We calculate the non-linearity parameters $f_{NL}$ and $g_{NL}$ in the sudden-decay approximation in this kind of model, and we find that one could get a large non-Gaussinity even if the curvaton dominates the total energy density before it decays, and this property will make the curvaton model much richer. We also calculate the probability density function of the primordial curvature perturbation in the sudden-decay approximation, as well as some moments of it.

description: The effect of the deposition of kinetic energy and neutralization energy of slow highly charged xenon ions on the process of the nanostructures creation at the surface of gold nanolayers is investigated. The nanolayers of thickness of 100 nm were prepared by e-beam evaporation of gold on crystalline silicon Si(100) substrate. The samples were irradiated at the Kielce EBIS facility of the Jan Kochanowski University (Kielce, Poland), under high vacuum conditions. The irradiations were performed for constant kinetic energy 280 keV and different ions charge states (Xe$^{q+}$, q = 25, 30, 35, 36 and 40) and for constant charge state Xe$^{35+}$ and different kinetic energies: 280 keV, 360 keV, 420 keV and 480 keV. The fluence of the ions was on the level of 10$^{10}$ ions/cm$^2$. Before and after irradiation the nanolayer surfaces were investigated using the atomic force microscope. As the result, well pronounced modifications of the nanolayer surfaces in the form of craters have been observed. A systematic analysis of the crater sizes (diameter on the surface and depth) allowed us to determine the influence of the deposited kinetic and the neutralization energy on the size of the obtained nanostructures. The results are theoretically interpreted within the micro-staircase model based on the quantum two-state vector model of the ionic Rydberg states population. The charge dependent ion-atom interaction potential inside the solid is used for the calculation of the nuclear stopping power. According to the model the formation of the nanostructures is governed by the processes of the ionic neutralization in front of the surface and the kinetic energy loss inside the solid.

description: We analyse the most general process of a generic highly excited string that decays into a less excited, yet generic, highly excited string emitting a tachyon. We provide a simple and compact analytic description of the decay process which discriminates between and within the structure of every single microstate of the initial and final highly excited string. Taking into account the random nature of the decay process we extract the energy spectrum of highly excited strings, microstate by microstate, finding a behavior which corresponds to the greybody emission spectrum. In addition, by exploiting the analytic control of the decay process, we identify the origin of thermal effects which are triggered by the chaotic nature of the highly excited string interactions modeled by the microstates structure.

Modelling of drinking water treatment and disinfection by-product formation with artificial neural networks
Creators: name: De Medeiros Paulino, Rafael
Publisher: name: University of British Columbia
Year: 2019

description: The source water for Coquitlam Water Treatment Plant (CWTP) originates from a watershed located in the mountains north of the City of Vancouver (BC, Canada), providing approximately 20% of the water demand for the metropolitan area. Treatment at CWTP consists of ozonation, followed by UV for primary disinfection and chlorination for secondary disinfection. Ozone is used to increase the UV transmittance (UVT) of the water, and to reduce the formation of chlorinated disinfection by-products (DBP) in the distribution system. Ozone addition at the CWTP is currently dosed proportionally to the flow being treated. This approach does not take into consideration the complex interactions that exist between varying raw water characteristics and ozone, and how these impact changes in UVT or DBP formation. Advanced numerical computational techniques, such as artificial neural networks (ANN), are increasingly being used to objectively identify optimal operating setpoints for complex systems. In the present study, two sets of ANN models were developed to optimize ozone addition for effective UV treatment and control of DBP formation. The first, the treatment system operation models, were used to predict pre-chlorination UVT, used as surrogate for the DBP formation potential, based on raw water characteristics and CWTP operational setpoints. The second, the distribution system models were used to predict the formation of total haloacetic acids (HAA), total trihalomethanes (THM) and two HAA fractions (DCAA and TCAA) in the distribution system based on raw and treated water characteristics. The treatment models could accurately predict pre-chlorination UVT. A moderate correlation was also observed between the measured and predicted DBP concentrations using the distribution system models, even though significant scatter was observed. This was likely due to the small available dataset and lack of reliable estimations of retention time and chlorine concentration in the distribution system. Scenario analyses with selected models were performed to investigate possible operational benefits of the implementation of these machine learning algorithms models to control ozone dosing. These suggested that savings could be achieved and high and constant level of pre-chlorination UVT could be maintained if ozone was dosed using these artificial neural network models.

description: The  effects  of  climate  change  in   variable  climate  a nd  more  extreme  weather  events  have
impacts  on  river  flow.  Accordingly,  Shafi e  River  has  impacted  the  socio- economy  of  the
downstream  communities  in  Mirab  Abaya  in  both  extreme  events  of  climatic  variability.  It
flows over 11.39 km in downstream via Mirab  Abaya downstream kebeles before draining into
the Lake Abaya.  It supports 6390 household in downstream catchments and 455 hectare of their
agricultural land area. On the other side it is resulted in great challenges to the study area due to
frequent season al flooding, river bank detachment and removal of top soil as well as impacts on
social livelihoods of the downstream communities during rainy season.
This  research  approach  followed  descriptive  method.  The  objectives  of  the  study  were  to
identify  the imp acts of Shafie River  on the  socio- economy of downstream communities in the
study  area.  Secondary  data  review,  key  informant  interview,  focus  group  discussion  and
household  interview  survey  were  used  as  methods  of  data  collection.  Both  qualitative  and
quantitative research  methods were used  for  the data analysis. The  major  findings are Shafie
River  has  negative  and  positive  impacts  on  environment  and  livelihood   of  downstream
communities,  but  there  are  high  negative ly   impacts  environmental  change  and  liveliho od
disruption.  During  summer  season  the  river  has  abnormal  flooding .  I t  is  the  cause  for
detachment of river bank area,  for  the comings of sand, gravel,  rock and  long trees  from  the
highland to lowlands and covered t he agricultural land ;  and affected the production as well as  it
resulted  in  washed  away  of  crops.  I n  addition   to  that,  settlements  homestead,  human  and
livestock, road  network and bridges  are affected by over  floods. Furthermore the educational
activities, hea l th, and psychological disturbance are also some of the impacts that are explained.
Whereas,  during  winter  season  where  there  is  scarce  rain,  and  there  are  high  water  using
activities in upstream as a result,  the flow of water reaches to downstream  be  decreasing. Due
to high computation for  irrigation conflicts are arisen .

description: The reliable electric supply of the cottage is object of researching in research work. The purpose of the work is to compare the possibility of electric supply of cottage from the central network and from an alternative source of energy, that is most suitable for this region. In this paper, a comparative analysis variant of the electric supply cottage was performed. Information sources related to alternative energy were considered. The question of using alternative energy sources for electricity supply is highly relevant at the present time, because the problem of exhaustion of natural resources and ecologically clean installations for generating electricity is becoming ever more relevant.
Study of Jet Shapes in Inclusive Jet Production in pp Collisions at sqrt(s) = 7 TeV using the ATLAS Detector
Creators: name: The ATLAS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Jet shapes have been measured in inclusive jet production in proton-proton collisions at sqrt(s) = 7 TeV using 3 pb^{-1} of data recorded by the ATLAS experiment at the LHC. Jets are reconstructed using the anti-kt algorithm with transverse momentum 30 GeV < pT < 600 GeV and rapidity in the region |y| < 2.8. The data are corrected for detector effects and compared to several leading-order QCD matrix elements plus parton shower Monte Carlo predictions, including different sets of parameters tuned to model fragmentation processes and underlying event contributions in the final state. The measured jets become narrower with increasing jet transverse momentum and the jet shapes present a moderate jet rapidity dependence. Within QCD, the data test a variety of perturbative and non-perturbative effects. In particular, the data show sensitivity to the details of the parton shower, fragmentation, and underlying event models in the Monte Carlo generators. For an appropriate choice of the parameters used in these models, the data are well described.

description: While Pancharatnam discovered the geometric phase in 1956, his work was not widely recognized until its endorsement by Berry in 1987, after which it received wide appreciation. However, because Pancharatnam's paper is unusually difficult to follow, his work has often been misinterpreted as referring to an evolution of states of polarization, just as Berry's work focused on a cycle of states, even though this consideration does not appear in Pancharatnam's work. We walk the reader through Pancharatnam's original derivation and show how Pancharatnam's approach connects to recent work in geometric phase. It is our hope to make this widely cited classic paper more accessible and better understood.
ASSESSING PERCEIVED IMPACTS AND CAUSES OF HUMAN  ENCROACHMENT INTO PROTECTED FOREST ECOSYSTEMS: THE CASE  OF AMARO WOREDA SOUTHERN ETHIOPIA.
Creators: name: TAGELE TAZEZE
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Protected areas are a cornerstone of forest conservation in developing countries like Ethiopia.
Yet little is known about the impacts of forest cover change on the socio-economic as well as
environmental issue on local communities, and even less pay attention about the relationship
between these effects. Forest reserve in Amaro Woreda has undergone drastic changes over
the year due to encroachment and deforestation by human activities. But the effect of forest
depletion on socio-economic as well as environment of local people demands attention. The
objective of this study is to assess the impact of human encroachment into the protected
forest ecosystem. One kebele was selected using purposive sampling from out of 17 kebeles
in the Woreda in which the protected forest is located. The data were collected from primary
and  secondary  sources  from  government  institution and  development  agencies.  Survey
questionnaire, individual interview and observation  were employed to collect  primary  data
and  unpublished  socio-economic  reports  were  used.  The  collected  data  were analyzed  by
using of descriptive statistics such as frequency, percentage and graphs. In order to clarify,
the satellite image maps were aided by using Arc GIS. The result of this study reveal that
expansion of farmland and settlement of the community,  low conservation management and
decision  making process  in the  government  side  were  viewed as  hindering  factor to affect
forest  protection  in  the  studied  area.  The  research  recommends  that land  resource
management officials and policy implementer’s should enhance people’s awareness through
educating and training to increase conservation practices on the ground in reasonable way to
preserve and protect forest resources to compromising of the future uses.

description: In the presence of feedback control by "Maxwell's demon," the second law of thermodynamics and the nonequilibrium equalities such as the Jarzynski equality need to be generalized. In this paper, we derive the generalized Jarzynski equalities for classical Hamiltonian dynamics based on the Liouville's theorem, which is the same approach as the original proof of the Jarzynski equality [Phys. Rev. Lett. 78, 2690 (1997)]. The obtained equalities lead to the generalizations of the second law of thermodynamics for the Hamiltonian systems in the presence of feedback control.

description: We analyze the single transverse-spin asymmetry (SSAs) for inclusive hadron production in the $pp$ collision at RHIC based on the twist-3 mechanism in QCD. As an origin of SSAs, we take into account of all kinds of pole contributions associated with the twist-3 quark-gluon correlation functions in the polarized proton. By the inclusion of the soft-fermion-pole contribution in addition to the soft-gluon-pole contribution, we find SSAs observed at RHIC are better described for all kinds of mesons. $P_T$-dependence of the asymmetry and the comparison with the FNAL data are also presented.

CHALLENGES AND OPPORTUNITIES OF RURAL POVERTY REDUCTION  IN DAMOT WOYDE WOREDA, WOLAITTA ZONE, SOUTHERN ETHIOPIA.
Creators: name: MENGISTU LEMMA BARATA.
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The focus of this study was to assess challenges and opportunities for rural poverty
reduction in Damot Woyde Woreda, Wolaitta zone, Southern Ethiopia. Data were
collected using questionnaire, FGD, interview and document analysis and also from rural
farmers at household level, DAs, kebele administrators, key informant rural farmers and
heads/ representatives of Work Process of Poverty Reduction oriented sectors.119
Sample households were selected using simple random sampling. Data gathered using
questionnaire were analyzed using the SPSS where descriptive statistics were used for the
purpose. As to the study findings, poverty is currently the phenomenon of the rural
population. Its level and depth (poverty) in the rural areas was manifested through
deprivation of consumption, food insecurity and reliance on PSNP and temporal
emergency food aid support. Different policies, strategies and practices were
implemented in the rural areas but lacked effectiveness in lifting out the majority of rural
farmers from the type of poverty they have faced. Result of the study indicated that rural
farmers faced strong challenges from climate change  (prolonged temperature and rain-
fall un certainty) and unexpected diseases of staple food crops such as maize (attacked by
maize  virus) and haricot bean.  The research findings also revealed that, though there
were challenges that faced the rural farmers in poverty reduction, there are also
untapped opportunities  (options and potentials)  in  the rural areas and the woreda that
contribute for poverty reduction and economic growth. Finally, the writer of this research
recommends that the woreda government, non-governmental organizations and
responsible government sectors should address challenges and efficient and effective
utilization of untapped opportunities. In addition, further researches should be conducted
in the same thematic areas

description: A method of images is applied to study the spontaneous emission of an atom inside a metallic wedge with an opening angle of $π/N$, where N is an arbitrary positive integer. We show the method of images gives a rate formula consistent with that from Quantum Electrodynamics. Using the method of images, we show the correspondence between the oscillations in the spontaneous emission rate and the closed-orbits of emitted photon going away and returning to the atom inside the wedge. The closed-orbits can be readily constructed using the method of images and they are also extracted from the spontaneous emission rate.

THE SOCIO ECONOMIC AND ENVIRONMENTAL ROLES OF  ENSET (Ensete ventricosum (Welw.) Cheesman) IN CHENCHA  WOREDA, SOUTH WESTERN ETHIOPIA
Creators: name: GEBRE GALLO
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Enset (Ensete ventricosum (Welw.) Cheesman) is a multipurpose indigenous crop
in Ethiopia. The cultivation of enset is a central farming activity due to its various
social, economic and environmental significances  for farm households. The main
objective of this research was  to  assess the  socio-economic  and environmental
roles of enset in Chencha woreda, southwestern Ethiopia. To meet the objectives,
a mixed method (both  qualitative and quantitative)  research approaches were
employed. To determine the size of sample kebeles, random sampling technique
was utilized. In this case, 209 sample households were selected from four kebeles.
To supplement and bridge household survey data, focus group discussion, key
informant interview and field observation were undertaken. Data were analyzed
by both quantitative and qualitative methods, using  simple descriptive statistics,
frequency, percentage,  tables, graphs and photographs.  The findings show  that enset plays a vital role in  the socio-economic life of the people in the study area.
In line with this, farm households consider that enset is a cultural identity crop, an
indication of status symbol, as a medicinal purpose,  primary source of food for
farm households and source of livestock feed. Its complex spongy root system form
mate-like structure in the root zones and its leaf canopy enabled an excellent
mechanism for  protecting soil against  erosion, runoff and land degradation,
conserve soil and moisture and increase soil fertility. Furthermore, it is drought
tolerant as compared to  root or tuber crops. Based on this research finding  the
major constraints that hinder the role of enset identified by farmers were disease
and lack of disease controlling measures for enset disease. Moreover, the attention
given by concerned bodies (government, NGOs and research organizations) to
improve the productivity of enset is low. Hence, this research recommends that its
sustainability needs close attention from research institutions, government and non-government organizations working in the area.

description: The gravitational waves and energy radiations from a spinning compact object with stellar mass in a circular orbit in the equatorial plane of a supermassive Kerr black hole are investigated in this paper. The effect how the spin acts on energy and angular moment fluxes is discussed in detail. The calculation results indicate that the spin of small body should be considered in waveform-template production for the upcoming gravitational wave detections. It is clear that when the direction of spin axes is the same as the orbitally angular momentum ("positive" spin), spin can decrease the energy fluxes which radiate to infinity. For antidirection spin ("negative"), the energy fluxes to infinity can be enlarged. And the relations between fluxes (both infinity and horizon) and spin look like quadratic functions. From frequency shift due to spin, we estimate the wave-phase accumulation during the inspiraling process of the particle. We find that the time of particle inspiral into the black hole is longer for positive spin and shorter for negative compared with the nonspinning particle. Especially, for extreme spin value, the energy radiation near the horizon of the extreme Kerr black hole is much more than that for the nonspinning one. And consequently, the maximum binging energy of the extreme spinning particle is much larger than that of the nonspinning particle.

description: For projectile fragmentation we work out details of a model whose origin can be traced back to the Bevalac era. The model positions itself between the phenomenological EPAX parametrization and microscopic transport models like "Heavy Ion Phase Space Exploration Model" (HIPSE) and antisymmetrised molecular dynamics(AMD). We apply the model to some recent data of projectile fragmentation of Ni on Ta and Be at beam energy 140 MeV/nucleon and some older data of Xe on Al at beam energy 790 MeV/nucleon. Reasonable values of cross-sections for various composites populated in the reactions are obtained.

Alpha tensor and dynamo excitation in turbulent fluids with anisotropic conductivity fluctuations

Year: 2023
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: A mean-field theory of the electrodynamics of a turbulent fluid is formulated under the assumption that the molecular electric conductivity is correlated with the turbulent velocity fluctuation in the (radial) direction, $\mathbf{g}$. It is shown that for such homogeneous fluids a strong turbulence-induced field advection anti-parallel to $\mathbf{g}$ arises almost independently of rotation. For rotating fluids, an extra $α$ effect appears with the known symmetries and with the expected maximum at the poles. Fast rotation, however, with Coriolis number exceeding unity suppresses this term. Numerical simulations of forced turbulence using the NIRVANA code demonstrate that the radial advection velocity, $γ$, always dominates the $α$ term. We show finally with simplified models that $α^2$ dynamos are strongly influenced by the radial pumping: for $γ<α$ the solutions become oscillatory, while for $γ>α$ they become highly exotic if they exist at all. In conclusion, dynamo models for slow and fast solid-body rotation on the basis of finite conductivity-velocity correlations are unlikely to work, at least for $α^2Ω$ dynamos without strong shear.

FARMERS‟ PERCEPTION OF LAND  DEGRADATION: THE CASE OF  DOYOGENA WOREDA KAMBATA TEMBARO ZONE OF SOUTH NATION,  NATIONALITY AND PEOPLE REGION
Creators: name: Abebe, Samuel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Land degradation has been the most serious problem that has treated the life of millions of people
in Ethiopia. The causes of land degradation are complex and diverse. Although  influenced by
natural and socio-economic factors, land degradation in Ethiopia is mainly a function of growing
population exploitative substance agriculture and rudimentary production methods but the problem
is not noticed and perceived by all farmers at the same fashion and level. Thus, the study is aimed
to  evaluate  the status of farmers‟ perception of  land degradation  and management practices in
doyogena woreda.  A  three-stage systematic sampling procedure was employed to select  three
sample kebeles and 129 sample household heads to collect primary data. Interview and observation
were also used to collect the relevant data. Descriptive statistics, chi-square analysis and Likert
scale were employed to show the frequency and percentage distribution of respondents. As the
study has been shown the farmers‟ perception of  steep slope , human population pressure, soil
erosion, deforestation, over cultivation, planting eucalyptus tree, lack of fertilizers, overgrazing,
poor farming practice and absence of crop rotation  as the  cause of  land degradation were found relatively reported by majority of the respondents except few educated farmers. For many farmers
reported that difficulty for farming increased of requirements of fertilizers, loss of agricultural
production, poverty and economic backwardness, landlessness and migration as consequence of
land degradation in study area. Concerning the perception to land management practices, closure of
grazing land,  terracing and tree planting are said to have been the least perceived as management
practices used by farmers except those who attached their life with in education. On the other hand,
organic manure, mulching, crop rotation, and tree planting were indicated as the frequently used
soil management practices  by large  house hold size. Pertaining the sources of information for
farmers‟ friends and relatives were found as the most important one. As the chi-square analysis has
been shown age,  education and household size were major factors that influence perception of
farmers. Therefore, continuous education, training and disseminating information is very important
to arouse farmers‟ perception of  land degradation and management practices by considering their
current perception level in the study area.

description: We study $\mathcal{W}_3$ toroidal conformal blocks for degenerate primary fields in AdS/CFT context. In the large central charge limit $\mathcal{W}_3$ algebra reduces to $\mathfrak{sl}_3$ algebra and $\mathfrak{sl}_3$ blocks are defined as contributions to $\mathcal{W}_3$ blocks coming from the generators of $\mathfrak{sl}_3$ subalgebra. We consider the construction of $\mathfrak{sl}_3$ toroidal blocks in terms of Wilson lines operators of $3d$ Chern-Simons gravity in the thermal AdS$_3$ space-time. According to the correspondence, degenerate primary fields are associated with Wilson lines operators acting in the corresponding finite-dimensional $\mathfrak{sl}_3$ representations. We verify this dual construction for one-point toroidal block using $\mathfrak{sl}_3$ tensor technique in the bulk theory and an algorithm based on AGT correspondence in the boundary CFT.
The effect of stellar encounters on the dark matter annihilation signal from prompt cusps

description: Prompt cusps are the densest quasi-equilibrium dark matter objects; one forms at the instant of collapse within every isolated peak of the initial cosmological density field. They have power-law density profiles, $ρ\propto r^{-1.5}$ with central phase-space density set by the primordial velocity dispersion of the dark matter. At late times they account for $\sim 1\%$ of the dark matter mass but for $>90\%$ of its annihilation luminosity in all but the densest regions, where they are tidally disrupted. Here we demonstrate that individual stellar encounters, rather than the mean galactic tide, are the dominant disruptors of prompt cusps within galaxies. Their cumulative effect is fully (though stochastically) characterised by an impulsive shock strength $B_* = 2πG\intρ_*({\bf x}(t))\, \mathrm{d}t$ where $ρ_*$, the total mass density in stars, is integrated over a cusp's entire post-formation trajectory. Stellar encounters and mean tides have only a small effect on the halo annihilation luminosity seen by distant observers, but this is not true for the Galactic halo because of the Sun's position. For a 100 GeV WIMP, Earth-mass prompt cusps are predicted, and stellar encounters suppress their mean annihilation luminosity by a factor of two already at 20 kpc, so that their annihilation emission is predicted to appear almost uniform over the sky. The Galactic Center $γ$-ray Excess is thus unaffected by cusps. If it is indeed dark matter annihilation radiation, then prompt cusps in the outer Galactic halo and beyond must account for 20-80% of the observed isotropic $γ$-ray background in the 1 to 10 GeV range.

The effect of sulfur dioxide and alternative fermentation techniques on the microbial communities and sensory profiles of wine
Creators: name: Morgan, Sydney Christian
Publisher: name: University of British Columbia
Year: 2019

description: Modern winemaking often involves the addition of sulfur dioxide (SO₂), to remove potential spoilage microbes from the grape juice, and the addition of commercial wine yeasts, to ensure a successful and timely completion of alcoholic fermentation. However, consumer demand is shifting towards low-SO₂ wines, and wines fermented by a collection of indigenous yeasts and bacteria. Many winemakers wish to produce these wines for their customers, but there is a current lack of research into the relative risks and rewards of these winemaking strategies. We investigated these topics, and found that both SO₂ addition and inoculation technique can significantly influence the fungal and bacterial communities and the sensory profiles of commercially-produced wines. Fermentations conducted without SO₂ were found to contain more vineyard-derived microorganisms and produced more fruity characters, while the fermentations conducted with SO₂ produced wines with less-desirable characteristics. Pied de cuve inoculation had a limited effect on the wine microbial communities and was inhibited by the addition of SO₂; when it persisted, it resulted in slower fermentations, and produced wines with more sweetness and body as compared to wines that did not receive the pied de cuve inoculum. At one commercial winery, we identified a highly diverse indigenous population of Saccharomyces uvarum, a yeast that is related to the main winemaking yeast, Saccharomyces cerevisiae. S. uvarum was able to compete with a commercial S. cerevisiae strain in controlled fermentations, and produced wines with a unique composition of aroma-active volatile compounds, showing its potential to be used as an indigenous yeast inoculum for locally-made wines. In summary, we showed that both SO₂ addition and fermentation technique (uninoculated or pied de cuve inoculation) can alter the microbial communities and sensory profiles of commercial and laboratory-made wines, and reported an indigenous yeast population in the Okanagan Valley winemaking region.

description: Ultrahigh energy neutrons and pions are likely to be produced in particle interactions inside cosmic ray sources and subsequently decay to neutrinos and other secondary particles ($π^\pm \rightarrow μ^\pmν_μ(\bar ν_μ),μ^\pm \rightarrow e^\pm \barν_μ(ν_μ) ν_e(\barν_e)$). In high magnetic fields of the cosmic acceleration sites, the ultrahigh energy charged particles may lose energy significantly due to synchrotron radiation before decay. We show that for gamma ray bursts in the internal shock model the flux of very high energy antineutrinos ($\bar ν_e$) produced from decaying ultrahigh energy neutrons can be more than the total neutrino flux produced in pion decay depending on the values of their Lorentz factors, luminosities and variability times.

description: It is known that a three Higgs doublet model (3HDM)symmetric under an exact $A_4$ symmetry is not compatible with nonzero quark masses and/or non-block-diagonal CKM matrix. We show that a 3HDM with softly broken $A_4$ terms in the scalar potential does allow for a fit of quark mass matrices. Moreover, the result is consistent with $m_h=125\textrm{GeV}$ and the $h \rightarrow WW, ZZ$ signal. We also checked numerically that, for each point that passes all the constraints, the minimum is a global minimum of the potential.

description: Rank-2 toric code (R2TC), a prototypical archetype of the discrete rank-2 symmetric gauge theory, has properties that differ from those of the standard toric code. Specifically, it features a blending of UV and IR in its ground state, restricted mobility of its quasiparticles, and variations in the braiding statistics of its quasiparticles based on their position. In this paper, we investigate various aspects of $\mathbb{Z}_N$ rank-2 gauge theory in ${(2+1)}$-dimensional spacetime. Firstly, we demonstrate that $U(1)$ rank-2 gauge theory can arise from ${U(1)\times U(1)}$ rank-1 gauge theory after condensing the gauge charges in a specific way. This construction scheme of $U(1)$ rank-2 gauge theory carries over to the $\mathbb{Z}_N$ case simply by Higgsing $U(1)$ to $\mathbb{Z}_N$, after which the resulting rank-2 gauge theory can be tuned to the R2TC. The holonomy operators of R2TC are readily identified using this scheme and are given clear physical interpretation as the pair creation/annihilation of various monopoles and dipoles. Explicit tensor network construction of the ground states of R2TC are given as two copies of the ground states of Kitaev's toric code that are `sewn together' according to the condensation scheme. In addition, through a similar anyon condensation protocol, we present a double semion version of rank-2 toric code whose flux excitations exhibit restricted mobility and semionic statistics. Finally, we identify the generalized discrete symmetries of the R2TC, which are much more complex than typical 1-form symmetries. They include conventional and unconventional 1-form symmetries, such as framed 1-form symmetries and what we call sublattice 1-form symmetries. Using these, we interpret the R2TC's unique properties (UV/IR mixing, position-dependent braiding, etc.) from the modern perspective of generalized spontaneous symmetry breaking and 't Hooft anomalies.
