description: Orbital degrees of freedom in condensed matters could play important roles in forming a variety of exotic electronic states by interacting with conduction electrons. In 4f electron systems, because of strong intra-atomic spin-orbit coupling, an orbitally degenerate state inherently carries quadrupolar degrees of freedom. The present work has focussed on a purely quadrupole-active system PrIr2Zn20 showing superconductivity in the presence of an antiferroquadrupole order at TQ = 0.11 K. We observed non-Fermi liquid (NFL) behaviors emerging in the electrical resistivity and the 4f contribution to the specific heat, C_4f, in the paramagnetic state at T > TQ. Moreover, in magnetic fields below 6 T, all data set of the electrical resistivity and C_4f(T) are well scaled with characteristic temperatures T0's. This is the first observation of the NFL state in the nonmagnetic quadrupole-active system, whose origin is intrinsically different from that observed in the vicinity of the conventional quantum critical point. It implies possible formation of a quadrupole Kondo lattice resulting from hybridization between the quadrupoles and the conduction electrons. Below 0.13 K, the electrical resistivity and C_4f(T) exhibit anomalies as B approaches 5 T. This is the manifestation of a field-induced crossover toward a Fermi-liquid ground state in the quadrupole Kondo lattice.

Optimization of Rock Bolt and Concrete Lining Combination in case of Awash-Kombolcha-Haragebeya Railway Tunnel Project
Creators: name: Sinodos, Shetie
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Tunnels are crucial infrastructures used for passage of humans, cars, trains or utility lines. Among this, tunnels used for road or rail purpose needs a great attention. The tunnel to serve its intended function, rock bolt and concrete lining are provided based on the ground condition. These two support systems are worthy and need great consideration as their impact remain on tunnel cost and convergence. Thus the optimum uses of these support systems are a challenge which demands the best design solution. Consequently, the study on tunnel rock bolt and concrete lining combination optimization which need study and improving, worth researching a lot. In this paper which is a case study, based on the design of data for optimization, the most influential support elements are selected. For different parameter combinations, the finite element methods have been performed followed by forming displacement parameter correlation. Likewise, the cost is represented by using polynomial model. Considering displacement and cost functions, the optimum combination of rock bolt and concrete lining has been found. The result show that the optimum combination is found if the number of rock bolt is 15 and concrete lining thickness 25 cm with in the constraint bolts [7,23] and lining thickness [10cm,40cm]. The optimized combination is modeled using numerical model and analysis along with the verification. The finite element analysis result gives total displacement of 6.34cm. But the observed total displacement inside the tunnel is about 60mm which is less than the predicted displacement of optimum combination using numerical analysis. The induced shear on concrete lining is 96.85 KN/m which is lower than the shear capacity of concrete lining. The total cost of rock bolt & concrete lining accounted for the optimum combination is $30,700 per 34 m2 tunnel rock bolt and concrete lining construction. Parametric study performed on pre stress rock bolt shows that increasing number of rock bolt would slightly increase stress and strain. Conversely, the convergence of tunnel is reduced. Similarly the plastic points are greatly reduced because of the pre stress rock bolt.
Power Reliability Analysis of DC Traction Power Supply System: A Case Study of Addis Ababa Light Rail Transit
Creators: name: Brian, Watuwa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: DC Railway Traction Power Supply System (TPPS) has been and is still widely used world over for train propulsion especially in the urban areas and inter- urban regions. With the evolution of electronic traction control technology giving compact size and reduced weight of chopper and inverter drives, DC railway traction has become advantageous especially where we have minimal provision for electrical clearances. Currently, the standard DC traction voltages are 750V, 1500V and 3000V which require less electrical clearance compared to AC Railway Traction Power Supply System catenary. The basic function of an electrical power system is to meet its customer's expectations while maintaining the acceptable levels of quality and continuity of supplies. The reliability level of DC Railway Traction Power Supply System is a major contributor to the quality of service provided by a railway authority, thus there is a link between reliability and quality of service. While most of the contingency situations may be predicted and counteracted on the design stage, only the real-life experience is the ultimate test for reliability. Reliability is regarded by many researchers as the science of failures and the work of a reliability engineer is to assess the trend of failure data and determine the rate of occurrence of failures as accurately as possible. This research, therefore, addresses the reliability question at AALRT through collection and analysis of power interruption data. This data is used to compute performance indicators or indices such as; Basic Reliability Indices (failure rate, MTBF, MTTR and availability), Customer Orientation Indices (SAIFI, SAIDI, CAIDI, ASAI and ASUI) and Energy and Cost Indices (EENS, AENS, ECOST and IEAR). From the period of study (2016, 2017 and 2018), this research finds out that the System Average Interruption Index SAIFI) is 7.47 interruptions per customer and System Average Interruption Duration Index (SAIDI) of 58.17 hours per customer. These indices are benchmarked with the those of other countries. A model of the AALRT TPSS is developed and three cases of potential reliability improvement alternatives are simulated using an ETAP software. These improvements gave an overall reduction in EENS of 80.869 MWhr/yr. A cost-benefit analysis of the reliability improvement alternatives is also done to justify the investment.

Knowledge and Attitude Towards Nursing Clinical Preceptorship Among Nurse Educators Working In Teaching Institutions In Addis Ababa, Ethiopia.
Creators: name: Admassu, Andreas
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Despite being a primary target of nursing education, clinical skills are still major areas of concern among students and novice graduates alike. Clinical preceptorship in nursing is a teaching and guidance program where students are paired with an experienced nurse in the clinical environment to equip them with clinical skills and nursing values. Since nurse educators are one of the primarily responsible bodies for its effective implementation and eventual success, this study assessed their knowledge and attitude towards clinical preceptorship. Objectives: To assess the knowledge and attitude towards nursing clinical preceptorship among nurse educators working in teaching institutions in Addis Ababa, Ethiopia. Methods: The study was conducted in Addis Ababa and used an institution-based descriptive cross-sectional study method mixed with qualitative approaches. 109 nurse educators participated in the quantitative data gathering while an in-depth interview with five participants involved in nursing education was used for qualitative data gathering. Results: Among the educators, 43.1% were found to be knowledgeable about nursing clinical preceptorship and its concepts whereas 96.3% had favorable attitude towards clinical preceptorship. A statistically significant association was found between the knowledge of educators towards preceptorship and their educational qualifications together with their teaching experiences. In-depth interviews revealed the existence of a theory-practice gap while shortage of facilities for clinical practice were the main challenges for clinical teachings. Role of nurse educators in clinical practice was also reported to be minimal. Conclusion and Recommendation: Less than half of the educators were found to have adequate knowledge towards nursing clinical preceptorship whereas the outlook towards it remains almost exclusively favorable. Additionally, clinical practical attachments of students is faced with a variety of challenges. Teaching institutions should focus on enhancing clinical skills of students and alleviate the problems it faces while hospitals and healthcare institutions should play their part in producing competent nursing workforce. Further studies related to clinical preceptorship and related matters is highly recommended. Keywords: Clinical Preceptorship, Clinical practice, Nurse Educator, Preceptor, Knowledge, Attitude
The fates of Solar system analogues with one additional distant planet

description: The potential existence of a distant planet ("Planet Nine") in the Solar system has prompted a re-think about the evolution of planetary systems. As the Sun transitions from a main sequence star into a white dwarf, Jupiter, Saturn, Uranus and Neptune are currently assumed to survive in expanded but otherwise unchanged orbits. However, a sufficiently-distant and sufficiently-massive extra planet would alter this quiescent end scenario through the combined effects of Solar giant branch mass loss and Galactic tides. Here, I estimate bounds for the mass and orbit of a distant extra planet that would incite future instability in systems with a Sun-like star and giant planets with masses and orbits equivalent to those of Jupiter, Saturn, Uranus and Neptune. I find that this boundary is diffuse and strongly dependent on each of the distant planet's orbital parameters. Nevertheless, I claim that instability occurs more often than not when the planet is as massive as Jupiter and harbours a semimajor axis exceeding about 300 au, or has a mass of a super-Earth and a semimajor axis exceeding about 3000 au. These results hold for orbital pericentres ranging from 100 to at least 400 au. This instability scenario might represent a common occurrence, as potentially evidenced by the ubiquity of metal pollution in white dwarf atmospheres throughout the Galaxy.

description: We infer distances and their asymmetric uncertainties for two million stars using the parallaxes published in the Gaia DR1 (GDR1) catalogue. We do this with two distance priors: A minimalist, isotropic prior assuming an exponentially decreasing space density with increasing distance, and an anisotropic prior derived from the observability of stars in a Milky Way model. We validate our results by comparing our distance estimates for 105 Cepheids which have more precise, independently estimated distances. For this sample we find that the Milky Way prior performs better (the RMS of the scaled residuals is 0.40) than the exponentially decreasing space density prior (RMS is 0.57), although for distances beyond 2 kpc the Milky Way prior performs worse, with a bias in the scaled residuals of -0.36 (vs. -0.07 for the exponentially decreasing space density prior). We do not attempt to include the photometric data in GDR1 due to the lack of reliable colour information. Our distance catalogue is available at http://www.mpia.de/homes/calj/tgas distances/main.html as well as at CDS. This should only be used to give individual distances. Combining data or testing models should be done with the original parallaxes, and attention paid to correlated and systematic uncertainties.

Toxicity Text Classification

description: The rapid growth of user-generated content on social media platforms in the form of text caused moderating toxic language manually to become an increasingly challenging task. Consequently, researchers have turned to artificial intelligence (AI) and machine learning (ML) models to detect and classify toxic comments automatically. However, these models often exhibit unintended bias against comments containing sensitive terms related to de- mographic groups, such as race and gender, which leads to unfair classifications of samples. In addition, most existing research on this topic focuses on fully supervised learning frame- works. Therefore, there is a growing need to explore fairness in semi-supervised toxicity detection due to the difficulty of annotating large amounts of data. In this thesis, we aim to address this gap by developing a fair generative-based semi-supervised framework for mitigating social bias in toxicity text classification. This framework consists of two parts, first, we trained a semi-supervised generative-based text classification model on the bench- mark toxicity datasets. Then, in the second step, we mitigated social bias in the trained classifier in step 1 using adversarial debiasing, to improve fairness. In this work, we use two different semi-supervised generative-based text classification models, NDAGAN and GANBERT (the difference between them is that the former adds negative data augmenta- tion to address some of the problems in GANBERT), to propose two fair semi-supervised models called FairNDAGAN and FairGANBERT. Finally, we compare the performance of the proposed fair semi-supervised models in terms of accuracy and fairness (equalized odds difference) against baselines to clarify the challenges of social fairness in semi-supervised toxicity text classification for the first time. Based on the experimental results, the key contributions of this research are: first, we propose a novel fair semi-supervised generative-based framework for fair toxicity text classification for the first time. Second, we show that we can achieve fairness in semi- supervised toxicity text classification without considerable loss of accuracy. Third, we demonstrate that achieving fairness at the coarse-grained level improves fairness at the fine-grained level but does not always guarantee it. Fourth, we justify the impact of the labeled and unlabeled data in terms of fairness and accuracy in the studied semi- supervised framework. Finally, we demonstrate the susceptibility of the supervised and semi-supervised models against data imbalance in terms of accuracy and fairness.

description: Complex nonlinear interaction phenomena between rail wagon and track significantly influence the dynamic performance. Thus to alleviate the drawback arise due to poor vehicle riding behavior, predicting parameter that quantify performance and certifying the wagon have inevitable significant. The objective of the study is to model and simulate dynamic performance of X4K container carrier freight wagon with 48 DOF on selected Ethio- Djibouti 1.8 km horizontal track i.e. continuous straight, transitional and circular track using Simpack 9.6 having considered critical operation maneuver i.e. 100Km/hr maximum wagon running speed and 93 ton total load. The obtained simulation result indicated; maximum derailment coefficient (Y/Q=0.24098), maximum lateral track shift force ΣFy=72,438.5N, ride quality index WZ(vertical)=2.5769 & WZ(lateral)=2.1786 and maximum wear index Γw=360.47N during curve negotiation have been found. Then conclusion drawn i.e. derailment coefficient obtained result and lateral track shift as it's compared UIC 518 validating standard, the propensity of wagon derailment validated safe range and the track shift force that induce lateral track irregularity, gauging validated in acceptable range. The ride quality index for both vertical and lateral direction that quantify the running performance of the vehicle validated as per CEN (2005) and the result found acceptable riding performance. While, the wear index resulted from simulation indicated beyond the allowable wear index limiting standard particularly during the wagon negotiate curved track and at intermediate & curved track junction. Consequently at operational speed maneuver (100Km/hr) the tendency of mild or severe wear occurrence between wheel/rail contacts validated high. To alleviate this problem optimization wear index have been conducted by consider operational speed reduction and a medium wear rate found in favor of reduced speed. Therefore the study recommended to use 70Km/hr during the wagon negotiates the curve and transition track.

description: We present measurements of the spatial mapping between (hot) baryons and the total matter in the Universe, via the cross-correlation between the thermal Sunyaev-Zeldovich (tSZ) map from Planck and the weak gravitational lensing maps from the Red Sequence Cluster Survey (RCSLenS). The cross-correlations are performed on the map level where all the sources (including diffuse intergalactic gas) contribute to the signal. We consider two configuration-space correlation function estimators, $ξ^{ y-κ}$ and $ξ^ {y-γ_{t}}$, and a Fourier space estimator, $C_{\ell}^{y-κ}$, in our analysis. We detect a significant correlation out to three degrees of angular separation on the sky. Based on statistical noise only, we can report 13$σ$ and 17$σ$ detections of the cross-correlation using the configuration-space $y-κ$ and $y-γ_{t}$ estimators, respectively. Including a heuristic estimate of the sampling variance yields a detection significance of 6$σ$ and 8$σ$, respectively. A similar level of detection is obtained from the Fourier-space estimator, $C_{\ell}^{y-κ}$. As each estimator probes different dynamical ranges, their combination improves the significance of the detection. We compare our measurements with predictions from the cosmo-OWLS suite of cosmological hydrodynamical simulations, where different galactic feedback models are implemented. We find that a model with considerable AGN feedback that removes large quantities of hot gas from galaxy groups and WMAP-7yr best-fit cosmological parameters provides the best match to the measurements. All baryonic models in the context of a Planck cosmology over-predict the observed signal. Similar cosmological conclusions are drawn when we employ a halo model with the observed `universal' pressure profile.

description: Cosmogenic nuclide analysis in sediment from the Earth’s largest rivers yields mean denudation rates of the sediment-producing areas that average out local variations commonly found in small rivers. Using this approach, we measured in situ cosmogenic 26Al and 10Be in sand of >50 large rivers over a range of climatic and tectonic regimes covering 32% of the Earth’s terrestrial surface. In 35% of the analyzed rivers, 26Al/10Be ratios are significantly lower than these nuclides´ surface-production-rate ratio of 6.75. We explain these low ratio by a combination of slow erosion and shielding in the source area, and we provide estimates of the buffering timescales of sediment transport using paired nuclides. In the other 65% of studied rivers, 26Al/10Be ratios are within uncertainty of their surface production-rate ratio, indicating cosmogenic steady state. For these rivers, we obtain a global source area denudation rate of 141 t/km2´yr (3.07 Gt/yr). By assuming that this sub-dataset is representative of the global land surface, we upscale to the total surface area for exorheic basins, thereby obtaining a global, millennial-scale denudation flux of 15.2 ± 2.8 Gt/yr. This value is slightly lower than published values from cosmogenic nuclides from small river basins (23 (+53/-16)) Gt/yr) upscaled using a global slope model, and also lower than modern sediment and dissolved loads exported to the oceans (24.0 Gt/yr). Our new approach confirms an estimate of global dissolved and solid matter transfer that converges to an encouragingly narrow range of within 35%.

description: In this article, we proved that, under weak and natural requirements, uncorrelated scattering (in particular WSSUS) channels can be modeled as stochastic integrals. Moreover, if we assume (not only uncorrelated but also) independent scattering, then the stochastic integral kernel is an additive stochastic process. This allows us to decompose an IS channel into a sum of independent channels; one deterministic, one with a Gaussian kernel, and two others described by the Levy measure of the additive process.

Assessment of Patient Satisfaction on Nursing Care Provided By Nursing Student in Black Lion Specialized Hospital, Addis Ababa, Ethiopia, 2015
Creators: name: Wondim, Amare
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Patient satisfaction is the degree of congruence between a patient's expectations of ideal nursing care and perception of the real nursing care receives. Satisfied patients are more likely to comply with treatment, take an active role in their own care, continue using health care services and stay within a health provider. On the other hand unsatisfied patient will not come back to the hospital, and it will lead to loss of income from the patient, as well as wastage of government resources and most importantly healing process is obviously compromised. In Ethiopia, studies conducted so far are very limited on subject of inquiry. As a result, this study was assessed the patient satisfaction with nursing Care provided by nursing student. Objective: The study assessed patient satisfaction on student nursing care service in Black lion hospital, Addis Ababa, Ethiopia, 2015. Methods: Institutional based cross sectional study design was used from April5-May5/2015 in Black lion hospital. A total of 365 patients were involved in the study. Interviewer administered structured questionnaires were employed to collect data. Data were analyzed using SPSS version 20.0. Bivariate and multiple logistic regression analysis were applied. Independent variables with p<0.05 in multiple logistic regression were considered as predictors of students' nursing care satisfaction. Result: In general, 197(54%) patients were satisfied with student nursing care service. patients who stayed for 2-10 night were less likely to be satisfied(AOR =0.437& 95% CI=0.210-.910) compared to those stayed for >22 nights. Patients who had previous admission were 2.0 times more likely to be satisfied than those who didn't had previous admission (AOR =2.01& 95% CI=1.100-3.703) and Patients who had other diseases in addition to current health problem were less likely to be satisfied (AOR =0.273& 95% CI= 0.139-.536) than those who didn't had. Patients who were under acute condition were 2.7 times more likely to be satisfied than those under chronic condition (AOR=2.7&95%CI=1.320-5.461). Conclusion: In this finding, a little over half or 54% of the study participants were satisfied with the overall students' nursing care services. This study also revealed predictors of satisfaction including educational status, number of night spent in the ward, history of previous admission, having other diseases in addition to current health problem and medical condition. Teaching institution in particular instructor should give emphasis for regular in-service education programme for student to refresh, up-to-date knowledge and skill on different aspects of patients care.

description: Stellar population synthesis models can now reproduce the photometry of old stellar systems (age $>$ 2 Gyr) in the near-infrared (NIR) bands at 3.4 and 4.6$μ$m (WISE W1 $\&$ W2 or IRAC 1 $\&$ 2). In this paper we derive stellar mass-to-light ratios for these and optical bands, and confirm that the NIR M/L shows dramatically reduced sensitivity to both age and metallicity compared to optical bands, and further, that this behavior leads to significantly more robust stellar masses for quiescent galaxies with [Fe/H] > -0.5 regardless of star formation history (SFH). We then use realistic early-type galaxy SFHs and metallicity distributions from the EAGLE simulations of galaxy formation to investigate two methods to determine the appropriate M/L for a galaxy: 1) We show that the uncertainties introduced by an unknown SFH can be largely removed using a spectroscopically inferred luminosity-weighted age and metallicity for the population to select the appropriate single stellar population (SSP) equivalent M/L. Using this method, the maximum systematic error due to SFH on the M/L of an early-type galaxy is $

description: Mobbing behavior, in addition to its complex cooperative aspects, is particularly suitable to study the mechanisms implicated in heterospecific communication. Indeed, various mechanisms ranging from pure learning to innate recognition have been proposed. One promising, yet understudied mechanism could be syntax recognition, especially given the latest works published on syntax comprehension in birds. In this experiment, we test whether great tits use both learning and syntax recognition when responding to heterospecifics. In the first part of the experiment, we demonstrate that great tits show different responses to the same heterospecific calls depending on their sympatric status. In a second part, we explore the impact of reorganizing the notes of the heterospecific mobbing calls to fit the syntax of great tits. Great tits showed an increased mobbing response toward the heterospecific calls when they shared their own call organization. Our results corroborate the recent finding that syntactic rules in bird calls may have a strong impact on their communication systems and enlighten how various mechanisms can be used by the same species to respond to heterospecific calls.

description: Systems thinking moves beyond the traditional view of the world as individual parts to be analyzed and understood toward a view of the world as an interactive, interlinked network working toward a common goal. All the parts of a system are inseparable from one another, making an understanding of the entire system essential to success. The academic library is a perfect example of an interlinked, interoperable system. The writings of systems thinker Barry Oshry provide insight into proper system operation and can be helpful to individuals seeking to create healthy library organizations.

description: Crystal structure prediction methods and first-principles calculations have been used to explore low-energy structures of carbon monoxide (CO). Contrary to the standard wisdom, the most stable structure of CO at ambient pressure was found to be a polymeric structure of Pna21 symmetry rather than a molecular solid. This phase is formed from six-membered (4 Carbon + 2 Oxygen) rings connected by C=C double bonds with two double-bonded oxygen atoms attached to each ring. Interestingly, the polymeric Pna21 phase of CO has a much higher energy density than trinitrotoluene (TNT). On compression to about 7 GPa, Pna21 is found to transform into another chain-like phase of Cc symmetry which has similar ring units to Pna21. On compression to 100 GPa it is energetically favorable for CO to polymerize to form a single-bonded Cmcm phase from another structure of Cmca symmetry composed of units similar to those found in the single-bonded I212121 structure. Thermodynamic stability of these structures was verified using calculations with different density functionals, including hybrid and van der Waals corrected functionals.

description: We demonstrated recently that polyelectrolytes with cationic moieties along the chain and a single anionic head are able to form physical hydrogels due to the reversible nature of the head-to-body ionic bond. Here we generate a variety of such polyelectrolytes with various cationic moieties and counterion combinations starting from a common polymeric platform. We show that the rheological properties (shear modulus, critical strain) of the final hydrogels can be modulated over three orders of magnitude depending on the cation/anion pair. Our data fit remarkably well within a scaling model involving a supramolecular head-to-tail single file between cross-links, akin to the behaviour of pine-processionary caterpillar. This model allows the quantitative measure of the amount of counterion condensation from standard rheology procedure.

Analysis of Rolling Contact Fatigue Damage and Fatigue Life Comparison of Rail Due to Cyclic Axle Load
Creators: name: Ayana, Gebremichael
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: This paper presents the analysis of rolling contact fatigue damage due to cyclic axle load between wheel/rail and fatigue life comparison between experimental and ANSYS results. The purpose is to see the fatigue life of the rail and to protect it from failure. .For this analysis a three-dimensional finite element model of the wheel/rail interaction is used to investigate the effect of the applied contact loading force at the straight area of the wheel tread and railhead surface. For the experimental part, fatigue test is conducted by taking specimens from the rail material and the specimens are modeled by CATIA V5 and analysis the effect with ANSYS 12.0 by applying different loads for the comparison of the fatigue life. Throughout the whole analysis, the Hertz contact theory assumptions are basically considered. Form the wheel/rail fatigue life analysis the result found is see the maximum life found by the applied load. The specimen numerical and experimental result shows that the experimental analysis is more preferable and precise. The application of this study is to identify and protect the rail from failure and to insure safety of the passengers and minimize maintenance cost.
title: Mobilization of redox-sensitive trace elements during water-rock interaction in presence of siderophores: Effects of solution pH, oxygen fugacity and weathering state

description: Siderophores are important biogenic chelators produced by plants, microbes and fungi, which promote the (bio-)availability of iron and other highly-charged cations in the natural environment. The hydroxamate siderophore desferrioxamine B (DFO-B) enhances the mobilization of certain trace elements that hydrolyze easily and hence are traditionally assumed as being ‘immobile’ during water-rock interaction. Leaching of different rock material with DFO-B under ambient conditions, for example, facilitates the formation of a very pronounced positive Ce anomaly in bulk-normalized patterns and fractionates the Th-U element pair, which we tentatively attributed to an oxidation of Ce(III) to Ce(IV) and U(IV) to U(VI). We here reports results of an investigation into the effects of solution pH, fO2 and weathering state of different rocks on the mobilization of redox-sensitive trace elements and their isotopes during water-rock interaction in presence of DFO-B. The impact of natural organic ligands on redox-sensitive elements may be largely underestimated. Siderophores are omnipresent today and may also have been present in the geological past. Our preliminary results indicate that the impact of solution pH on fractionation of redox-sensitive trace elements is rather small, but that fractionation is strongly controlled by oxygen fugacity and by the weathering state of the studied rock. Siderophores have the potential to significantly catalyze the oxidation of these elements even under strongly hypoxic conditions.

description: Mobile big data contains vast statistical features in various dimensions, including spatial, temporal, and the underlying social domain. Understanding and exploiting the features of mobile data from a social network perspective will be extremely beneficial to wireless networks, from planning, operation, and maintenance to optimization and marketing. In this paper, we categorize and analyze the big data collected from real wireless cellular networks. Then, we study the social characteristics of mobile big data and highlight several research directions for mobile big data in the social computing areas.

Influence of quantum conservation laws on particle production in hadron collisions

description: Conservation laws strongly influence production of particles in high-energy particle collisions. Effects connected to these mechanisms were studied in details using correlation techniques in \ee\ collisions. At the time, models were tuned to correctly reproduce the measurements. Similar studies for hadron-hadron collisions have never been performed, until recent ALICE measurements. ALICE has reported on studies of untriggered two-particle angular correlations of identified particles ($π$, $K$, and p) measured in pp collisions at center-of-mass energy of $\sqrt{s}=$ 7 TeV. Those preliminary results confirm that also in hadron-hadron collisions, at much higher energies, conservation laws strongly influence the shape of the correlation functions for different particle types and must be taken into account while analysing the data. Moreover, they show that the contemporary models (PYTHIA, PHOJET) no longer reproduce the experimental data well.

description: We provide further details on a recent proposal addressing the nature of the dark sectors in cosmology and demonstrate that all current observations related to Dark Matter can be explained by the presence of a heavy spin-2 particle. Massive spin-2 fields and their gravitational interactions are uniquely described by ghost-free bimetric theory, which is a minimal and natural extension of General Relativity. In this setup, the largeness of the physical Planck mass is naturally related to extremely weak couplings of the heavy spin-2 field to baryonic matter and therefore explains the absence of signals in experiments dedicated to Dark Matter searches. It also ensures the phenomenological viability of our model as we confirm by comparing it with cosmological and local tests of gravity. At the same time, the spin-2 field possesses standard gravitational interactions and it decays universally into all Standard Model fields but not into massless gravitons. Matching the measured DM abundance together with the requirement of stability constrains the spin-2 mass to be in the 1 to 100 TeV range.
