Fluctuations in and out of equilibrium: Thermalization, quantum measurements and Coulomb disorder

This purely theoretical thesis covers aspects of two contemporary research fields: the non equilibrium dynamics in quantum systems and the electronic properties of three dimensional topological insulators. In the first part we investigate the non equilibrium dynamics in closed quantum systems. Thanks to recent technologies, especially from the field of ultracold quantum gases, it is possible to realize such systems in the laboratory. The focus is on the influence of hydrodynamic slow modes on the thermalization process. Generic systems in equilibrium, either classical or quantum, in equilibrium are described by thermodynamics. This is characterized by an ensemble of maximal entropy, but constrained by macroscopically conserved quantities. We will show that these conservation laws slow down thermalization and the final equilibrium state can be approached only algebraically in time. When the conservation laws are violated thermalization takes place exponential in time. In a different study we calculate probability distributions of projective quantum measurements. Newly developed quantum microscopes provide the opportunity to realize new measurement protocols which go far beyond the conventional measurements of correlation functions. The second part of this thesis is dedicated to a new class of materials known as three dimensional topological insulators. Also here new experimental techniques have made it possible to fabricate these materials to a high enough quality that their topological nature is revealed. However, their transport properties are not fully understood yet. Motivated by unusual experimental results in the optical conductivity we have investigated the formation and thermal destruction of spatially localized electron and hole doped regions. These are caused by charged impurities which are introduced into the material in order to make the bulk insulating. Our theoretical results are in agreement with the experiment and can explain the results semi quantitatively. Furthermore, we study emergent lengthscales in the bulk as well as close to the conducting surface.
On Mixing in Pairwise Markov Random Fields with Application to Social Networks
Venue: WAW

We consider pairwise Markov random fields which have a number of important applications in statistical physics, image processing and machine learning such as Ising model and labeling problem to name a couple. Our own motivation comes from the need to produce synthetic models for social networks with attributes. First, we give conditions for rapid mixing of the associated Glauber dynamics and consider interesting particular cases. Then, for pairwise Markov random fields with submodular energy functions we construct monotone perfect simulation.
Object Oriented Metrics and Quality Attributes: A Survey
Venue: INFOS '16

Design phase is considered one of the most important phases of software development process. Considering design quality is a significant indicator to guarantee a good product. Despite the fact that this phase is more important, it takes less effort in processing but it can take a large part of the total effort consumed in correcting earlier issues that resulted from bad design decisions. If the design quality of a product wasn't previously considered, the cost of fixing bad design issues after software delivery will be very high. Recently researchers have introduced several object oriented metrics for identifying design problems and avoiding such issues at earlier development phases. This paper initiates a survey regarding object oriented metrics and their quality attributes. Also it shows the relationship between internal and external quality attributes and identify a group of practical and common used metrics which having a significant impact on design quality.

A Cu catalyzed four component cascade reaction to construct b ester g amino ketones.
Venue: Organic biomolecular chemistry

Herein, a novel Cu catalyzed four component cascade reaction, which encompasses styrenes, diazo compounds, amines, and tert butyl hydroperoxide (TBHP) was developed for the synthesis of b ester g amino ketones. Mechanistically, this transformation was initiated by the interception of an electrophilic Cu based carbene with nucleophilic a aminoalkyl radicals, followed by a radical cascade process and an ionic Kornblum DeLaMare reaction. The methodology was also distinguished by its wide substrate scope, easily available starting materials, and operational simplicity.
Cancer and fertility preservation: international recommendations from an expert meeting
Venue: BMC Medicine

In the last years, thanks to the improvement in the prognosis of cancer patients, a growing attention has been given to the fertility issues. International guidelines on fertility preservation in cancer patients recommend that physicians discuss, as early as possible, with all patients of reproductive age their risk of infertility from the disease and/or treatment and their interest in having children after cancer, and help with informed fertility preservation decisions. As recommended by the American Society of Clinical Oncology and the European Society for Medical Oncology, sperm cryopreservation and embryo/oocyte cryopreservation are standard strategies for fertility preservations in male and female patients, respectively; other strategies (e.g. pharmacological protection of the gonads and gonadal tissue cryopreservation) are considered experimental techniques. However, since then, new data have become available, and several issues in this field are still controversial and should be addressed by both patients and their treating physicians.In April 2015, physicians with expertise in the field of fertility preservation in cancer patients from several European countries were invited in Genova (Italy) to participate in a workshop on the topic of "cancer and fertility preservation" A total of ten controversial issues were discussed at the conference. Experts were asked to present an up to date review of the literature published on these topics and the presentation of own unpublished data was encouraged. On the basis of the data presented, as well as the expertise of the invited speakers, a total of ten recommendations were discussed and prepared with the aim to help physicians in counseling their young patients interested in fertility preservation.Although there is a great interest in this field, due to the lack of large prospective cohort studies and randomized trials on these topics, the level of evidence is not higher than 3 for most of the recommendations highlighting the need of further research efforts in many areas of this field. The participation to the ongoing registries and prospective studies is crucial to acquire more robust information in order to provide evidence based recommendations.
Moving Object Detection for Driving Assistance System Based on Improved ORB Feature Matching
Venue: IDCS

In order to overcome the shortcoming of origin feature matching and extract moving objects accurately for real time driving assistance system. We present a novel moving object detection method based on improved ORB. Firstly, The ORB is used to extract and match feature points. Secondly, we establish an improved Feature Matching Optimization Strategy to remove the mismatched pairs more efficiently. Then differential multiplication and morphology processing are used to accurately segment the moving objects. Finally, a Driving Impact Degree Alarm Mechanism is proposed to give the driver an early warning to take braking measures. Experimental results show that the accuracy of feature matching could be increased to 97 by our method and the processing speed is fast enough to meet the requirements for real time driving assistance system. It also has certain advantages in dealing with noise suppression.
Cognitive behavioral and pharmacological treatments of OCD in children: A systematic review and meta analysis.
Venue: Journal of anxiety disorders

Obsessive compulsive disorder (OCD) is ranked by the World Health Organization (WHO) among the 10 most debilitating disorders. The treatments which have been found effective are cognitive behavior therapy (CBT) and serotonin reuptake inhibitors (SRI) This meta analysis includes all RCTs of CBT (25) and SRI (9) for OCD in youth using the Children's Yale Brown Obsessive Compulsive Scale (C YBOCS) CBT yielded significantly lower attrition (12.7% than SRI (23.5% and placebo (24.7% The effect sizes for comparisons of CBT with waiting list (1.53) placebo (0.93) and SRI with placebo (0.51) were significant, whereas CBT vs. SRI (0.22) and Combo (CBT+SRI) vs. CBT (0.14) were not. Regarding response rate CBT (70% and Combo (66% were significantly higher than SRI (49% which was higher than placebo (29% and WLC (13% As for remission CBT (53% and Combo (49% were significantly higher than SRI (24% placebo (15% and WLC (10% which did not differ from each other. Combo was not more effective than CBT alone irrespective of initial severity of the samples. The randomized controlled trials (RCTs) have a number of methodological problems and recommendations for improving research methodology are discussed as well as clinical implications of the findings.
A meta analysis of family accommodation and OCD symptom severity.
Venue: Clinical psychology review

Family accommodation in obsessive compulsive disorder (OCD) is characterized by myriad behaviors, such as modifying family routines, facilitating avoidance, and engaging in compulsions to reduce obsessional distress. It has been linked to various deleterious outcomes including increased functional impairment and poorer treatment response for OCD. Although extant literature suggests a linear relationship between family accommodation and OCD symptom severity, the magnitude and statistical significance of this association has been inconsistent across studies, indicating that moderators may be influencing this relationship. The present study examined this relationship using meta analytic techniques, and investigated sample dependent (age, gender, comorbid anxiety/mood disorders) and methodological (administration method and number of items used in family accommodation measure, informant type, sample size, publication year) moderators. Forty one studies were included in the present meta analysis, and the overall effect size (ES) for the correlation between family accommodation and OCD symptom severity was moderate (r=.42) Moderator analyses revealed that the number of items on the family accommodation scale moderated the ES. No other sample dependent or methodological characteristics emerged as moderators. In addition to being the first systematic examination of family accommodation moderators, these results highlight the moderate relationship between family accommodation and OCD severity that is influenced by measurement scales. Findings may be used to guide clinical care and inform future investigations by providing a more nuanced understanding of family accommodation in OCD.
A robust resource allocation algorithm for packet BIC UFMC 5G wireless communications
Venue: 2016 24th European Signal Processing Conference (EUSIPCO)

In this paper, we present a novel resource allocation (RA) algorithm for packet Universal Filtered Multi Carrier (UFMC) BIC based communications, the latter being a novel modulation format possibly envisaged to be applied in 5G wireless systems. Assuming the perfect knowledge of the channel and capitalizing on the specific UFMC signal waveform, the proposed RA strategy optimizes the coding rate and bit loading within the overall bandwidth along with the per subband power distribution. In the presence of a carrier offset and over fading selective channels, the results we obtained are twofold: i) the UFMC format reveals to be more robust than the conventional OFDM scheme; ii) the performance of the UFMC system itself is further boosted by the optimal choice of radio resources evaluated by the proposed RA algorithm.
Invited Review: Grazing management options in meeting objectives of grazing experiments12

Decisions on which grazing management option to use in grazing experiments can be critical in meeting research objectives and generating information for the scientific community or technologies that meets the needs of forage based enterprises. It is necessary to have an understanding of animal performance relationships with stocking rate (SR) forage mass, and forage allowance to make informed decisions on how to best manage forages and grazing in an experiment. Stocking rates can be varied using the put and take procedure to maintain the optimum grazing pressure as forage growth varies during the grazing season. The alternative to put and take stocking is to use a range of fixed SR that generate light to heavy grazing pressure responses. Put and take controls grazing pressure in evaluating animal performance and stocking rate responses to treatments, whereas fixed SR controls SR to evaluate animal performance and grazing pressure responses on treatments and treatment by SR interactions. Decisions to use either continuous or rotational stocking methods will be based on a need to complement existing grazing practices of the forage based livestock industry or to determine best management practices. Relationships of animal performance with SR, forage mass, and forage allowance will be presented and used to discuss the advantages and disadvantages of put and take and fixed stocking procedures, and the considerations for using either continuous or rotational stocking methods.
B Cell Development in the Bone Marrow Is Regulated by Homeostatic Feedback Exerted by Mature B Cells
Venue: Front. Immunol.

Cellular homeostasis in the B cell compartment is strictly imposed to balance cell production and cell loss. However, it is not clear whether B cell development in the bone marrow is an autonomous process or subjected to regulation by the peripheral B cell compartment. To specifically address this question, we used mice transgenic for human CD20, where effective depletion of B lineage cells is obtained upon administration of mouse anti human CD20 antibodies, in the absence of any effect on other cell lineages and/or tissues. We followed the kinetics of B cell return to equilibrium by BrdU labeling and flow cytometry and analyzed the resulting data by mathematical modeling. Labeling was much faster in depleted mice. Compared to control mice, B cell depleted mice exhibited a higher proliferation rate in the pro /pre B compartment, and higher cell death and lower differentiation in the immature B cell compartment. We validated the first result by analysis of the expression of Ki67, the nuclear protein expressed in proliferating cells, and the second using Annexin V staining. Collectively, our results suggest that B lymphopoiesis is subjected to homeostatic feedback mechanisms imposed by mature B cells in the peripheral compartment.

Research of Improved Adaptive Median Filter Algorithm

This paper proposes an improved adaptive median filter algorithm for highly corrupted images with salt and pepper noise. First of all, the improved adaptive median filter makes full use of the relationship between the gray value of the current pixel and the gray values of the neighborhood pixels. It calculates the corresponding threshold by adaptive processing. Second, all the pixels are classified into signal and noise pixels using the relationship of the difference between maximum and minimum values of the pixels and threshold. Finally, it deals with the noise and signal point using different methods. Experimental results show that the proposed algorithm has better performance for capabilities of noise removal, and preserves the image edge detail information, especially effective for the cases when the images are highly corrupted.

Face Detection A Literature Survey

The extensive research in the field of face detection can be gauged from the fact of great increase in face capturing devises. Millions of people are recorded everyday in cctv's, video recorder, media, social sites like YouTube, Vimeo, Facebook, Instagram and lot more. Face plays a core part in distinguishing and identifying a person and hence face detection is much sought after. Other factors, such as security have also provided impetus to research in face identification. Though, other detection techniques such as iris scanning, finger prints scanning are also a way to identify a person but the problem it contains is the fact that it requires a dedicated hardware system and human resource for it. Such problems are not faced in face identification as face is detected through passive resources that do not require involvement from the user side. In this paper we would we would compare and look at the ongoing face detecting techniques and the underlying properties.

The mechanism of action of tofacitinib an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis.
Venue: Clinical and experimental rheumatology

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease characterised by infiltration of immune cells into the affected synovium, release of inflammatory cytokines and degradative mediators, and subsequent joint damage. Both innate and adaptive arms of the immune response play a role, with activation of immune cells leading to dysregulated expression of inflammatory cytokines. Cytokines work within a complex regulatory network in RA, signalling through different intracellular kinase pathways to modulate recruitment, activation and function of immune cells and other leukocytes. As our understanding of RA has advanced, intracellular signalling pathways such as Janus kinase (JAK) pathways have emerged as key hubs in the cytokine network and, therefore, important as therapeutic targets. Tofacitinib is an oral JAK inhibitor for the treatment of RA. Tofacitinib is a targeted small molecule, and an innovative advance in RA therapy, which modulates cytokines critical to the progression of immune and inflammatory responses. Herein we describe the mechanism of action of tofacitinib and the impact of JAK inhibition on the immune and inflammatory responses in RA.
