description: The usage of dual‐purpose chicken breeds – a chicken breed which provides meat and eggs at the same time is one of the discussed alternatives to prevent cockerel chicks of laying hens from being killed for economic reasons.
Therefore, the aim of this study is to analyse consumers’ perspective on dual‐purpose chickens. To get an insight into consumers’ perspective, we initially conducted six focus groups with German consumers focussing on their chicken meat and egg preferences, perception of chicken farming and attitudes towards dual‐purpose chicken breeds. The results show that most of the participants were aware of the killing of day‐old chicks. However, alternatives were scarcely known. After giving the participants information about dual‐purpose chickens, they were generally in favour of this chicken breed. Some participants raised concerns regarding the economic efficiency and the higher product prices. For others, ethical values predominated. All in all, the results demonstrate that the
discussants have specific expectations regarding the husbandry conditions but also regarding the product characteristics and the labelling of dual‐purpose chickens.

description: With an enormous rise in the application of smartphones, the need for highly efficient radio architectures has increased significantly. Modern communication systems will be adopting a 5th Generation (5G) standard for meeting the demands of the users efficiently. Analog mixers are a vital component of any transmitter and perform the necessary task of up-converting a signal. However, there are certain limitations associated with mixers including energy inefficiency. To eliminate these effects, three-way mixerless transmitter (TWMT) architecture has been proposed in the literature. Existing behavioral model for such an architecture make use of the digital splitters and combiners. In this thesis, we propose a Triadic Complex Memory Polynomial based model for the forward and inverse modeling of TWMT using analog combiners and splitters leading to a realistic scenario. Extensive simulations and measurements have been used to validate their performance. The model meet the desired design criteria concerning NMSE and ACLR.

description: © 2020 The Author(s). Background: While several multigene signatures are available for predicting breast cancer prognosis, particularly in early stage disease, effective molecular indicators are needed, especially for triple-negative carcinomas, to improve treatments and predict diagnostic outcomes. The objective of this study was to identify transcriptional regulatory networks to better understand mechanisms giving rise to breast cancer development and to incorporate this information into a model for predicting clinical outcomes. Methods: Gene expression profiles from 1097 breast cancer patients were retrieved from The Cancer Genome Atlas (TCGA). Breast cancer-specific transcription regulatory information was identified by considering the binding site information from ENCODE and the top co-expressed targets in TCGA using a nonlinear approach. We then used this information to predict breast cancer patient survival outcome. Result: We built a multiple regulator-based prediction model for breast cancer. This model was validated in more than 5000 breast cancer patients from the Gene Expression Omnibus (GEO) databases. We demonstrated our regulator model was significantly associated with clinical stage and that cell cycle and DNA replication related pathways were significantly enriched in high regulator risk patients. Conclusion: Our findings demonstrate that transcriptional regulator activities can predict patient survival. This finding provides additional biological insights into the mechanisms of breast cancer progression.

description: This paper has been presented as a theme lecture and published in the proceedings of 7ICEGE, Rome, Italy.ABSTRACT: Results of numerical modelling of gravity retaining walls using the OpenSees finite element facilities are presented. Simplified design analyses for gravity walls are often based on pseudo-static modelling. The purpose of the paper is to check on the validity of the pseudo-static approach by calculating, using results from nonlinear time history analyses, the accumulation of permanent displacements during the course of dynamic excitation. The walls are founded on dense dry sand and backfilled with dense or medium dry sand. The sand is modelled using the Manzari and Defalias constitutive relationship available in OpenSees. Two configurations of a moderately stiff reinforced concrete cantilever gravity retaining wall are investigated. The results of varying the foundation heel and toe projections are presented. Ricker wavelets applied at the base of the foundation layer are used for the dynamic response rather than earthquake time histories. It is concluded that when the walls are subject to horizontal accelerations equivalent to the pseudo-static acceleration at which permanent displacements are initiated, the residual displacements from OpenSees are modest and likely to be regarded as indicative of satisfactory performance. Results from the application of repeated Ricker wavelet excitation are also presented.

description: Gaussian process models -also called Kriging models- are often used as mathematical approximations of expensive experiments. However, the number of observation required for building an emulator becomes unrealistic when using classical covariance kernels when the dimension of input increases. In oder to get round the curse of dimensionality, a popular approach is to consider simplified models such as additive models. The ambition of the present work is to give an insight into covariance kernels that are well suited for building additive Kriging models and to describe some properties of the resulting models.

description: In recent years, Machine Learning (ML) applications for manufacturing have reached a high degree of maturity and can be considered as a suitable tool for improving production performance. In addition, ML applications can be used in many other production areas to enhance sustainability within the manufacturing process. One area is storing and transporting bulk materials with metal Intermediate Bulk Containers (IBC). These IBCs are currently used solely for their primary purpose of storage and transportation of raw and finished goods. Hence, while in use , IBCs are often a black box that does not provide additional value to manufacturers. Equipping IBCs with sensor technology can provide such value: new data can be generated along the entire supply chain and production processes, taking the sustainability of production to a new level. Within the research project smart.CONSERVE, we use this additional data, for example, to monitor the stored food's critical characteristics or to establish predictive maintenance for IBCs. Thus, storing produced goods in defective IBCs can be avoided and wasting resources can be prevented. This publication describes how smart IBCs in the food industry can increase supply chain visibility and reduce food waste. To illustrate this, we present possible use cases enabled by new data availabilities. Additionally, we provide insights into how these use cases can be transferred to other industries. Besides, we exemplify the many opportunities for manufacturers to develop new smart services and ML applications based on the collected data - and how this can support manufacturers in achieving higher levels of sustainability.

The work is made available under the Creative Commons CC0 public domain dedication. The actin cytoskeleton plays a central role in establishing cell polarity and shape during embryonic morphogenesis. Daam1, a member of the Formin family of actin cytoskeleton regulators, is a Dvl2-binding protein that functions in the Wnt/Planar Cell Polarity (PCP) pathway. To examine the role of the Daam proteins in mammalian development, we generated Daam-deficient mice by gene targeting and found that Daam1, but not Daam2, is necessary for fetal survival. Embryonic development of Daam1 mutants was delayed most likely due to functional defects in the labyrinthine layer of the placenta. Examination of Daam2 and Daam1/2 double mutants revealed that Daam1 and Daam2 are functionally redundant during placental development. Of note, neural tube closure defects (NTD), which are observed in several mammalian PCP mutants, are not observed in Wnt5a or Daam1 single mutants, but arise in Daam1;Wnt5a double mutants. These findings demonstrate a unique function for Daam genes in placental development and are consistent with a role for Daam1 in the Wnt/PCP pathway in mammals.

description: © Copyright © 2020 Canciello, Teti, Mazzotti, Falconi, Russo, Giordano and Barboni. Amniotic membrane (AM) is considered an important medical device with many applications in regenerative medicine. The therapeutic properties of AM are due to its resistant extracellular matrix and to the large number of bioactive molecules released by its cells. An important goal that still remains to be achieved is the identification of cultural and preservation protocols able to maintain in time the membrane morphology and the biological properties of its cells. Recently, our research group demonstrated that progesterone (P4) is crucial in preventing the loss of the epithelial phenotype of amniotic epithelial cells in vitro. Followed by this premise, it has been evaluated whether P4 may also affect AM properties in a short-term culture. Results confirm that P4 preserves AM integrity and architecture with respect to untreated AM, which showed alterations in morphology. Transmission electron microscopy (TEM) analyses demonstrate that P4 also maintains unaltered cell–cell junctions, nuclear status, and intracellular organelles. On the contrary, an untreated AM experienced an extensive cell death and a strong reduction of immunomodulatory properties, measured in terms of anti-inflammatory cytokine expression and secretion. Overall, these results could open to new strategies to ameliorate the protocols for cryopreservation and tissue culture, which represent preliminary stages of AM application in regenerative medicine.

description: The development of the navy and the extension of connected capacities is one of the focuses of the military evolution in the People’s Republic of China (later on: China). The directions of the improvement appear to be clear, though achieving their aims are a question of decades, not years. These Chinese steps, the progress they make, new ship classes they develop, advanced technologies they produce will take the upcoming decades to reach their goals – even if sometimes the Western media exaggerates the potential threat posed by the Chinese army.

The paper shortly presents the geopolitical environment of the country, after that analyses the necessity of a blue-water navy, the development they have already started and tries to project ahead their capacities and the relevance of that future Navy.
Biomimetic System for the Application of Nanomaterials in Fluid Purification: Removal of Arsenic with Ferrihydrite

Year: 2020

description: Copyright © 2020 American Chemical Society. The use of nanomaterials has transformed fields such as medicine and electronics. However, aggregation of nanomaterials in aqueous solutions, difficult recovery of spent nano-adsorbents from reactors, and a tremendous pressure loss caused by nano-adsorbents in adsorption columns have prevented the wide-scale use of nano-adsorbents in industrial applications for water purification. An over-reliance on traditional adsorption media for fluid purification practices has slowed innovation in this field. This study serves as a proof of concept for a new approach in utilizing nano-adsorbents in water treatment. A system based on the concept of renal dialysis was used to treat a solution of arsenite using two-line ferrihydrite (Fh) under environmental conditions. The performance was compared to traditional batch studies, and environmental variables pH and Eh were monitored. The system removed 67 and 91% of arsenite at 1.22 and 2.61 g/L Fh loadings, respectively, in comparison to batch experiments that removed 82 and 94% for similar loadings. Operational conditions and the physical design of the vessel limited the extent of removal that could be obtained with the system. Design advantages, shortcomings, and required improvements are discussed.

description: The performance of a radio occultation GPS receiver carrier tracking loop, subjected to ionospheric scintillations, is studied in this thesis. A physics-based simulation of high-latitude ionospheric disturbances for radio occultation signals has been employed to generate a variety of test cases to assess receiver performance. This scintillation simulator is built on an existing tool and is novel in allowing simulation of high-latitude ionospheric perturbations on multiple frequencies for radio occultation signals. Further, an experimental simulation method is developed which extracts scintillation-induced perturbations directly from real observations and applies them to a nominal GPS signal. Simulation results are validated against scintillation perturbations extracted from real radio occultation signals collected during solar maximum. The simulation approach is found to closely represent the real effects of scintillation. Scintillated signals are analyzed for effectiveness of detrending methods and selection of cutoff frequency for filtering scintillation data and capturing scintillation information. It is determined through spectral analysis that a higher cutoff frequency is required for filtering high-latitude scintillation signals. Also, scintillation measurements are dependent on the method applied for detrending. According to the studies conducted in this thesis, receiver tracking performance depends on both scintillation levels and the receiver mode (tracking versus acquisition). The receiver can track strong scintillation signals provided sufficient time to acquire signals pre-scintillations. Signal acquisition and tracking during scintillations, however, is challenging and might fail for severe scintillation conditions. Also, it is found that the presence of amplitude scintillation alone does not cause significant carrier performance degradation unless it is severe enough to reduce signal power below tracking threshold level leading to loss of lock. Strong phase scintillations, on the other hand, result in noticeable tracking loop performance degradation and measurement errors.

The effect is a consequence of a subtle interplay between interaction delays, noise and the excitable character of a single neuron. Dependence of the cluster properties on the time-lag, noise intensity and the synaptic strength is investigated.

description: © The Author(s) 2020. The conventional wisdom in molecular evolution is to apply parameter-rich models of nucleotide and amino acid substitutions for estimating divergence times. However, the actual extent of the difference between time estimates produced by highly complex models compared with those from simple models is yet to be quantified for contemporary data sets that frequently contain sequences from many species and genes. In a reanalysis of many large multispecies alignments from diverse groups of taxa, we found that the use of the simplest models can produce divergence time estimates and credibility intervals similar to those obtained from the complex models applied in the original studies. This result is surprising because the use of simple models underestimates sequence divergence for all the data sets analyzed. We found three fundamental reasons for the observed robustness of time estimates to model complexity in many practical data sets. First, the estimates of branch lengths and node-to-tip distances under the simplest model show an approximately linear relationship with those produced by using the most complex models applied on data sets with many sequences. Second, relaxed clock methods automatically adjust rates on branches that experience considerable underestimation of sequence divergences, resulting in time estimates that are similar to those from complex models. And, third, the inclusion of even a few good calibrations in an analysis can reduce the difference in time estimates from simple and complex models. The robustness of time estimates to model complexity in these empirical data analyses is encouraging, because all phylogenomics studies use statistical models that are oversimplified descriptions of actual evolutionary substitution processes.

description: We investigated age-related decline in adult learning of Dutch as an additional language (Ln) in speaking, writing, listening, and reading proficiency test scores for 56,024 adult immigrants with 50 L1s who came to the Netherlands for study or work. Performance for all four language skills turned out to decline monotonically after an age of arrival of about 25 years, similar to developmental trajectories observed in earlier aging research on additional language learning and in aging research on cognitive abilities. Also, linguistic dissimilarity increased age-related decline across all four language skills, but speaking in particular. We measured linguistic dissimilarity between first languages (L1s = 50) and Dutch (Ln) for morphology, vocabulary, and phonology. Our conclusion is that the L1 language background influences the effects of age-related decline in adult language learning, and that the constraints involved reflect both biological (language learning ability) and experience-based (acquired L1 proficiency) cognitive resources.

description: Foster children are at-risk for negative life outcomes; however, many become functioning adults. Resiliency helps explain why some individuals become functioning adults despite experiencing adversity. Research has identified supportive adult relationships as important in promoting resiliency. This research examined natural and formal mentoring relationships with Alberta foster children and whether identification of a mentor related to resiliency levels. Participants included 145 youth aged 12 to 17 in foster care. The majority of participants identified a mentor (93.1%), with few identified from formal mentoring programs. Foster parents were the most frequently identified and their identification was significantly related to resiliency levels. Nonparental mentors did not demonstrate a link to resiliency levels. More Aboriginal participants scored in the highly vulnerable range. This research provided insight into the resiliency of foster youth and who they experience as supportive adults. It highlighted the importance of foster parents and family members for foster youth.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. The Gram-negative Campylobacter jejuni is a major cause of foodborne gastroenteritis in humans worldwide. The cytotoxic effects of Campylobacter have been mainly ascribed to the actions of the cytolethal distending toxin (CDT): it is mandatory to put in evidence risk factors for sequela development, such as reactive arthritis (ReA) and Guillain-Barré syndrome (GBS). Several researches are directed to managing symptom severity and the possible onset of sequelae. We found for the first time that rapamycin (RM) is able to largely inhibit the action of C. jejuni lysate CDT in U937 cells, and to partially avoid the activation of specific sub-lethal effects. In fact, we observed that the ability of this drug to redirect lysosomal compartment, stimulate ER-remodeling (highlighted by ER–lysosome and ER–mitochondria contacts), protect mitochondria network, and downregulate CD317/tetherin, is an important component of membrane microdomains. In particular, lysosomes are involved in the process of the reduction of intoxication, until the final step of lysosome exocytosis. Our results indicate that rapamycin confers protection against C. jejuni bacterial lysate insults to myeloid cells.
Laboratory Investigation of Infiltration Processes in Frozen Soil and the Influence of Antecedent Moisture Content and Macroporosity

subject: FOS: Earth and related environmental sciences

description: Snowmelt infiltration into frozen soil can recharge soil moisture and groundwater storage. In order to better understand the complex processes involved, the influence of antecedent moisture content and macroporosity on infiltration in frozen soil was investigated. Infiltration experiments on frozen macroporous and non-macroporous soil columns revealed dry macroporous soil can produce infiltration rates reaching 10^3 to 10^4 mm day^-1, 3 to 4 orders of magnitude larger than dry non-macroporous soil. Results suggest rapid infiltration was a result of preferential flow through air-filled macropores. These findings imply significant infiltration is possible at all landscape positions (uplands and depressions) under dry soil conditions. Under wet conditions, regardless of the presence of macropores, infiltration was restricted by the slow thawing rate of ice, producing infiltration rates of a mere 2.8 to 5.0 mm day^-1. Restricted infiltrability will increase surface runoff to local depressions, where deep drainage occurs once the soil thaws.

description: © 2020 by the authors. Licensee MDPI, Basel, Switzerland. T. An air-backed diaphragm is the key structure of most dynamic pressure sensors and plays a critical role in determining the sensor performance. Our previous analytical model investigated the influence of air cavity length on the sensitivity and bandwidth. The model found that as the cavity length decreases, the static sensitivity monotonically decreases, and the fundamental natural frequency shows a three-stage trend: increasing in the long-cavity-length range, reaching a plateau value in the medium-cavity-length range, and decreasing in the short-cavity-length range, which cannot be captured by the widely used lumped model. In this study, we conducted the first experimental measurements to validate these findings. Pressure sensors with a circular polyimide diaphragm and a backing air cavity with an adjustable length were designed, fabricated, and characterized, from which the static sensitivities and fundamental natural frequencies were obtained as a function of the cavity length. A further parametric study was conducted by changing the in-plane tension in the diaphragm. A finite element model was developed in COMSOL to investigate the effects of thermoviscous damping and provide validation for the experimental study. Along with the analytical model, this study provides a new understanding and important design guidelines for dynamic pressure sensors with air-backed diaphragms.

description: An algorithm was developed to detect melt onset over Arctic sea ice using high-resolution SAR images from RADARSAT. The algorithm is based on the temporal evolution of the SAR backscatter coefficient (σ⁰), using an ice type specific threshold approach that also corrects for backscatter incidence angle variation. Using 4457 RADARSAT images, the algorithm was applied over sea ice in the northern CAA, thus generating a new time series of melt onset from 1997-2014. The mean annual melt onset date was on YD 164±4 (mid–June). No significant trend was found over the 18-year period, however, variability increased in post-2007 years. An earlier (later) melt onset was associated with increased (decreased) solar energy absorption and subsequently associated in lighter (heavier) September sea ice coverage in the northern CAA. RADARSAT estimates of melt onset were found to be in good agreement but more robust compared to passive microwave and scatterometer estimates.

Munhwaŏ : the ‘cultured language’ and language branding in North Korea, 1964-1984
Creators: name: Jentzsch, Spencer James
Publisher: name: University of British Columbia
Year: 2010

description: Branding is the process of giving a product a life of its own—a sort of personification of the business world. In language branding, the marketing principles of branding are applied to language. Since Kim Il Sung’s ‘talk with linguists’ in 1964 and 1966, North Korea has maintained a consistent language policy and method of language branding of their newly ‘branded’ language of Munhwaŏ. Throughout the process of language branding, North Korea’s popular language planning journal, Munhwaŏ Haksŭp ‘Cultured Language Learning’, communicates Munhwaŏ—with the North Korean government’s pre-packaged identity—to rank-and-file North Koreans. In accordance with Olin and Kotler’s claims that corporation branding techniques are applicable to other disciplines, this thesis examines publications of Munhwaŏ Haksŭp to discuss the rebranding of the North Korean variety of the Korean language as Munhwaŏ. Munhwaŏ Haksŭp first repackages this new language through maldadŭmgi ‘vocabulary refinement’, instructions on proper writing and proper speech, and promoting concepts of language primordialism. Second, Munhwaŏ Haksŭp separates the newly defined language of Munhwaŏ from its sister language in South Korea by focusing on the ideopolitical and linguistic differences between the two, particularly criticizing the influx of English, Japanese, and Sino-Korean loanwords into the South Korean variety. The distinction between the two nation’s languages, however, is limited, as can be seen from North Korean attempts to prevent Munhwaŏ from straying too far from South Korea’s Han’gugŏ. Finally, Munhwaŏ Haksŭp compares Munhwaŏ to the languages of the rest of the world, heavily promoting the ususŏng (usu-nature or superiority) of Munhwaŏ—and, by extension, the North Korea—through articles focusing on script nationalism, aural aesthetics, abundance of expression, and politeness. Whether a conscious decision by the North Korean government or not, the evidence provided in this thesis overwhelmingly suggests that the marketing principles of branding—giving the brand a story, a name, and a symbol, asserting differences in image with a rival brand, and, above all, promoting the uniqueness of the brand—were systematically and consistently applied to Munhwaŏ on the pages of Munhwaŏ Haksŭp.

description: Intangible factors, e.g. the availability of infrastructure at a production site, and implicit knowledge, have an essential influence on the decision-making in global production networks. However, the consideration of intangible factors and implicit knowledge, especially in planning the production network configuration and determining the production network strategy, is usually done implicitly or only based on qualitative and subjective estimations. This can cause biased decisions and miscalculations that make additional and expensive adaptions in the global production network necessary. In order to address this challenge, this paper develops a methodology based on fuzzy inference systems (FIS) to enable a more quantitative and objective consideration of strategic network capabilities influenced by intangible factors and implicit knowledge. For this, the strategic network capabilities are described by several criteria aggregated through one or multiple cascading fuzzy inference systems. The resulting metrics for strategic network capabilities as well as intangible factors are normalized and comparable. Transparency about strategic network capabilities allows a focused discussion about the strategic configuration of the production network. Moreover, the metrics can also be used in other quantitative approaches such as mathematical optimization. The proposed methodology is demonstrated with 70 intangible factors, six strategic network capabilities, and 21 sub-capabilities from academic literature. It can be shown that the developed methodology can map intangible factors and implicit knowledge in a very flexible and detailed manner by selecting and weighting the describing criteria within the FIS in order to quantify strategic network capabilities.

description: Introduction:
 Anticoagulants and corticosteroids are the main treatment for COVID-19, therefore increases the incidence of Upper Gastrointestinal tract Bleeding (UGIB) in these patients. The aim of this study is to investigate the incidence and characteristics of UGIB among COVID -19 patients in our centre to determine the best management approach. Methodology:
 Demographics, endoscopic findings, intervention and outcomes of UGIB among COVID-19 patients has been retrospectively evaluated for patient admitted to Sungai Buloh Hospital from March 2020 to March 2021. Results:
 The incidence of UGIB among COVID-19 patients in our centre during the study period was 0.4% (n=72). 90.9% of the case referred for UGIB were COVID-19 Category 4 patients who requires oxygen support(69%). 65% of them were started on anticoagulant and 70.8% were started on steroid therapy. The common presentation for UGIB in these patients were unexplained reduction in haemoglobin level(51.4%) and the most common endoscopic finding among 53% of the patient who were scoped was peptic ulcer(40%) .However, only 15% out of the 72 referred cases needed significant endoscopic intervention, i.e clipping, injection or cauterization. Mean systolic pressure of 148(p=0.006) and mean platelet level of less than 180(p=0.011) were found to be statistically significant in impacting the need for significant endoscopic intervention. The incidence of unplanned rescope and mortality were found to be not statistically impacted by endoscopic intervention done. Conclusion:
 Peptic ulcer disease is the most common finding in UGIB cases among COVID-19 patient. However endoscopic intervention was only needed in 15% of cases, therefore conservative management would be an acceptable option in management UGIB in COVID-19 patients.

description: One of the major reasons for newcomers voluntarily leaving organizations can be linked to inadequate socialization (Allen, 2006; Feldman, 1989; Fisher, 1986). Socialization has been described as a period of extensive learning where newcomers gather large amounts of information to reduce the uncertainty and complexity of their world. However, a unifying theory to explain how this process occurs is missing. Social learning theory offers a compelling framework to address this theoretical gap and, at the same time, it suggests that newcomers will pay attention to ethical information and that this learning will be important for turnover intentions. Socialization has been studied extensively from the process to the tactics of socialization (Ostroff & Kozlowski, 1992), but little research has examined the ethical side of socialization and its relation to turnover (Bauer & Erdogan, 2012). Drawing from the ethical leadership model, and using a sample of 297 first-year apprentices in Alberta’s oil and gas industry, this study sought to examine whether socialization influences the perceptions of organizational ethics and whether this leads to turnover intentions. A second follow-up study utilizing 800 newcomers examined whether ethical leadership perceptions explained the path between ethical socialization to turnover and eventually to deviant behaviours. Additionally, behavioural integrity of the leader and moral disengagement by the individual are examined as moderators of this model. Results showed that perceptions of organizational ethics (Study1) and perceptions of ethical leadership (Study 2) fully mediated the socialization and turnover path. The behavioural integrity of the leader was a significant moderator (such that when behavioural integrity was low, socialization had a stronger impact on turnover). Moreover, moral disengagement was also a significant moderator of organizational ethics in predicting turnover (such that when moral disengagement was high, ethical perceptions had a weaker relationship with turnover). Finally, moral disengagement interacted with turnover intentions to predict organizational deviant behaviours (when moral disengagement was high, turnover intentions was a stronger predictor of deviant behavior compared to when moral disengagement was low).

description: We linearize the field equations for higher order theories of gravity that contain scalar invariants other than the Ricci scalar. We find that besides a massless spin-2 field (the standard graviton), the theory contains also spin-0 and spin-2 massive modes with the latter being, in general, ghost modes. The rate at which such particles would emit gravitational Cherenkov radiation is calculated for some interesting physical cases.

description: Heterogeneous cellular networks (HetNets), comprising one or more tiers of small base stations (BSs) overlaid on the tier of well-planned macro BSs, have been commonly recognized as a cost-effective solution to cater to explosive demands on mobile data traffic. However, HetNets also bring some unique challenges such as unplanned deployment of small BSs and increased complexity of interference management. Interference in HetNets becomes one of the major obstacles to capacity improvement and coverage enhancement. In this thesis, analytical approaches are developed to investigate interference statistics and the performance of 2-tier HetNets including coverage probability and spectral efficiency in mathematical expression, and some insights are revealed on the relationships of interference statistics and network performance with system parameters such as frequency reuse factor, transmission probability, and the signal-to-interference ratio (SIR) gap from Shannon capacity. Specifically, the interference and performance impact of Rician fading and lognormal shadowing are analytically investigated, first based on the Poisson point process (PPP) model where the locations of BSs in each tier are modeled as a PPP. Second, a hybrid model of HetNets is established which considers both location regularity of macro BSs and topological randomness of small BSs, where the coverage probability and the spectral efficiency are derived under different propagation conditions and the significance of macro BS deployment planning is revealed. Third, based on the aforementioned analyses, a well-known interference management technique of fractional frequency reuse (FFR) applied in the tier of macro BSs is studied in detail, and its optimal parameter settings in terms of spectral efficiency and suitable environments are identified. Finally, a particular interest is attached to multiple antenna technologies including classical beamforming and transmit diversity, which are studied with consideration of the impact of intra-tier and inter-tier interference in HetNets.

description: Using analytical techniques and Langevin dynamics simulations, we investigate the dynamics of polymer translocation through a nanochannel embedded in two dimensions under an applied external field. We examine the translocation time for various ratio of the channel length $L$ to the polymer length $N$. For short channels $L\ll N$, the translocation time $τ\sim N^{1+ν}$ under weak driving force $F$, while $τ\sim F^{-1}L$ for long channels $L\gg N$, independent of the chain length $N$. Moreover, we observe a minimum of translocation time as a function of $L/N$ for different driving forces and channel widths. These results are interpreted by the waiting time of a single segment.
