AN INVITATION TO HIGHER TEICHMÜLLER THEORY

Riemann surfaces are of fundamental importance in many areas of mathematics and theoretical physics. The study of the moduli space of Riemann surfaces of a fixed topological type is intimately related to the study of the Teichmüller space of that surface, together with the action of the mapping class group. Classical Teichmüller theory has many facets and involves the interplay of various methods from geometry, analysis, dynamics and algebraic geometry. In recent years, higher Teichmüller theory emerged as a new field in mathematics. It builds as well on a combination of methods from different areas of mathematics. The goal of my talk is to invite the reader to get to know and to get involved into higher Teichmüller theory by describing some of its
Desigualdades socioeconómicas en salud bucal: caries dental en niños de 6 a 12 años de edad

Objective. To explore the association between caries indices in primary and permanent dentition and socioeconomic indicators at the individual and ecologic levels in 6-12 year old children. Materials and methods. A comparative analysis of two datasets depicting oral health status in Campeche, México, with 2,939 children distributed equally by age and sex, was carried out. Oral health indices were contrasted at different cut-off points in primary and permanent dentitions (dmft, DMFT, dmft+DMFT and SiC indices) with independent variables such as place of residence (urban, marginal-urban) and mother’s highest level of schooling (years of formal education) as socioeconomic variables (SES), as well as other sociodemographic variables using models of binary logistic regression in STATA 8.2®. Results. The mean age was 8.85 ± 1.83 years and 56.6% were girls. Nine models were generated in which changes in socioeconomic variables were linked to changes in oral health features in this community (both in terms of prevalence and severity), except for DMFT > 0 at 12 years of age. Conclusions. In general, children of lower SES had greater caries experience and higher caries severity, in both primary and permanent dentitions. The relationships between oral health disparities and independent variables were confirmed in children living in geographically contiguous areas.
Does the eccentric Nordic Hamstring exercise have an effect on isokinetic muscle strength imbalance and dynamic jumping performance in female rugby union players

The aim of this study was to evaluate the effect of an eccentric hamstring specific training programme on the percentage of bilateral muscle strength imbalance and maximal vertical jump height. Twenty-four, injury free female rugby union players took part in this study. Participants were split into two groups; intervention group (Nordic Hamstring (NH) (n = 13) and control group (n = 11)). Both groups completed normal training; the NH group completed a concurrent NH programme for 10 weeks. Pre and post-training concentric/concentric isokinetic testing of peak torque was performed for hamstrings of both legs at 60 ◦ /s. Vertical jump height was also assessed. In the NH group, there was a significant decrease in mean percentage bilateral hamstring strength imbalance (pre = 10.39 ± 3.53, post = 4.63 ± 2.81, p< 0.05). There was also a significant increase in vertical jump height for the NH group (pre = 31.22 ± 4.8 cm, post = 35.93 ± 4.5 cm, p< 0.05). The NH programme caused favourable adaptations to bilateral hamstring strength imbalance and dynamic lower body performance. A programme based on NH exercise is potentially an effective preventive and rehabilitation tool for hamstring injury.
Efficacy of Sudarshan kriya Yoga in Enhancing Comprehensive Well-Being

Yogic breathing is a unique method for balancing the ANS and influencing psychology and stress related disorders. Sudarshan Kriya Yoga (SKY) is a form of yoga practice that emphasizes rhythmic breathing exercises. The present study was undertaken with an aim to study the effect of SKY on stress levels as well as mental health of participants. The pre and post study involved a sample of 14 (7 males, 7 females) with age range from 23 to 60 years. Perceived Stress Scale, Self Esteem Scale and Mental Health Index which measures anxiety, depression, loss of behavioral/ environmental control, general positive affect, life satisfaction, psychological distress, psychological well being as well as a global mental health were administered. Results indicate that there is a significant decrease in anxiety and depression levels, increase in GPA, and increase in level of psychological well being, more life satisfaction and improved MHI score post intervention. Although no improvement was observed in the feelings of psychological distress, there was a highly significant rise in levels of psychological well-being. However, no improvements in the levels of self esteem or emotional ties have been observed. Implications of introduction of such programs in meeting the challenges of day to day life as well as for addressing specific problems have been discussed.
Delivering Aging Services: Stability and Change in Policies and Programs

Although many great programs exist, funding remains a top concern in preserving available resources to help elders age at home and in their communities.Aplethora of services and programs has been established to enable older adults to main- tain their quality of life as they age at home and in their communities. But as the baby boom generation begins in earnest to comprise the age 65-plus demographic, it is more important than ever to understand the current system of aging services and the future challenges of meeting the service needs of older adults.This article's purpose is to describe briefly a dynamic and interactive continuum of services and programs available for older adults and their family care providers. We focus our attention primarily on programs and services that receive funds through the Older American's Act (OAA) and other federal entities; for more detailed information about these and other programs and services see Community Resources for Older Adults: Programs and Services in an Era of Change (Wacker and Roberto, 2014). The dis- cussion that follows mirrors the Continuum of Services framework (Figure 1 on page 15), be- ginning with community resource services that benefit older adults with low levels of dependency, followed by support services, and concluding with a discussion of long-term-care services.Community ResourcesCommunity resources are services that benefit older adults with low levels of dependency. These services offer older participants opportunities to enhance their personal and social well-being.Information, Referral and AssistanceThe goal of Information, Referral and Assistance (IRA volunteers receive a minimal hourly wage to provide emo- tional support and assistance to frail, homebound older adults living alone (Senior Corps, 2008). The Foster Grandparent Program links the skills and interests of older adults who are at least 55 years old, out of the workforce, and low-income with children who have academic and personal problems. Foster grandparents provide individu- alized support, assistance, and mentorship to at-risk children to enable their physical, mental, emotional, and social development.Implemented in 1993, the National Commu- nity Service Trust Act created the AmeriCorps Initiative, which became the new home for these three national service programs. The Edward M. Kennedy Serve America Act of 2009 reauth- orized the volunteer programs and expanded opportunities for elders to participate in national service programs. …
Coronary circulation : from basic mechanisms to clinical implications

Few diagnostic methods in Cardiology have heralded such revolutionary developments as the introduction of coronary arteriography. When, in the early 1960's, Dr. F. Mason Sones demonstrated that visualization of the coronary anatomy in living humans was not only feasible but sufficiently safe and reliable to be used as a clinical tool in the evaluation of patients with known or suspected ischemic heart disease, the thus far somewhat neglected area of coronary circulation became the focus of interest. Naturally, for a considerable period of time a great deal of emphasis was placed upon coronary anatomy. Simple relations between narrowing lesions, impediment to flow, and prognosis were assumed to exist. Spectacular results of surgical coronary revascularization seemed to confirm this concept. Gradually it has become evident that the pathophysiology of coronary artery disease is considerably more complex. Diagnostic methods were introduced to assess and quantify exercise-induced myocardial ischemia. At first, these tests were used mainly to achieve a more discriminative selection of candidates for coronary arteriography and the coronary arteriogram remained the gold standard. Currently, these techniques have evolved to the point where they provide valuable functional and metabolic information. They have become powerful independent tools in clinical investigations and evaluation of individual patients.
pH Indicators As Chemical Reagents for the Enhancement of Footwear Marks

Enhancement of weak two-dimensional shoemarks is often necessary due to the poor image detail. Thiocyanate is regarded in the literature as the most effective reagent for the chemical enhancement of footwear marks. In this study we have examined the possibility of using pH indicators, Bromophenol Blue and Bromocresol Green, as chemical reagents for the enhancement of footwear marks. The performance of these reagents on various surfaces, such as plastic sheets, brown paper, cardboard, porcelain bathroom tiles and cotton cloth, was compared to that of the thiocyanate reagent. It was found that these reagents were much more effective than ammonium thiocyanate for the samples of shoeprints in various regions of Israel. The mechanism of chemical enhancement of footwear marks by these reagents was elucidated. A solution of 1% Bromophenol Blue and 5% of water in methanol was chosen as the Bromophenol Blue formulation in this laboratory for the chemical enhancement of shoeprints.

An Electromagnetic Variable Stiffness Device for Semiactive Seat Suspension Vibration Control

This article introduces a rotary semiactive variable stiffness (VS) device, including its system design and model validation. A variable damping (VD) device and springs can form mechanical networks with specific topologies, and the VD device can control the equivalent stiffness of the network by varying its damping. The proposed rotary electromagnetic VS device consists of an electromagnetic VD device and a torsion spring, which are in series, while a planetary gear reducer is used to amplify the torque output of the VS device. The models of the electromagnetic VD and VS devices are both built and validated with tests. Then, a seat suspension applies the VS device by installing the device in the center of its scissors structure. Bump and random vibration experiments are implemented to validate the effectiveness of the proposed VS system for seat suspension vibration control. The new system has merits in controllability and energy efficiency. It is easier to design the controller than the conventional one with magnetorheological damper due to the linear damping of the electromagnetic VD device. Besides, the system energy consumption is low and has energy harvesting capability. The proposed semiactive electromagnetic VS device also has potential in other practical applicationss.
Microglial Phagocytosis of Neurons: Diminishing Neuronal Loss in Traumatic, Infectious, Inflammatory, and Autoimmune CNS Disorders

Errors in neuron-microglial interaction are known to lead to microglial phagocytosis of live neurons and excessive neuronal loss, potentially yielding poorer clinical outcomes. Factors that affect neuron-microglial interaction have the potential to influence the error rate. Clinical comorbidities that unfavorably impact neuron-microglial interaction may promote a higher rate of neuronal loss, to the detriment of patient outcome. This paper proposes that many common, clinically modifiable comorbidities have a common thread, in that they all influence neuron-microglial interactions. Comorbidities like traumatic brain injury, infection, stress, neuroinflammation, loss of neuronal metabolic integrity, poor growth factor status, and other factors, all have the potential to alter communication between neurons and microglia. When this occurs, microglial phagocytosis of live neurons can increase. In addition, microglia can shift into a morphological form in which they express major histocompatibility complex II (MHC-II), allowing them to function as antigen presenting cells that present neuronal debris as antigen to invading T cells. This can increase risk for the development of CNS autoimmunity, or can exacerbate existing CNS autoimmunity. The detrimental influence of these comorbidities has the potential to contribute to the mosaic of factors that determine patient outcome in some CNS pathologies that have neuropsychiatric involvement, including TBI and CNS disorders with autoimmune components, where excessive neuronal loss can yield poorer clinical outcomes. Recognition of the impact of these comorbidities may contribute to an understanding of the common clinical observation that many seemingly disparate factors contribute to the overall picture of case management and clinical outcome in these complex disorders. In a clinical setting, knowing how these comorbidities can influence neuron-microglial interaction can help focus surveillance and care on a broader group of potential therapeutic targets. Accordingly, an interest in the mechanisms underlying the influence of these factors on neuron-microglial interactions is appropriate. Neuron-microglial interaction is reviewed, and the various mechanisms by which these potential comorbidities influence neuro-microglial interaction are described.
Reconsideration the Current Guidelines for Lipid-lowering Therapy in Patients with Coronary Artery Disease

Background：Despite the proven benefits of cholesterol-lowering therapy in patients with coronary artery disease (CAD, there is no consensual opinion on the guidelines for cholesterol-lowering therapy in patients with CAD in Korea. The aim of this study was to to evaluate the risks of CAD with respect to cholesterol level, and to consider the current guidelines for cholesterol-lowering therapy as a secondary prevention measure in patients with CAD. Materials and Methods：600 consecutive patients were assigned into two groups -the coronary artery disease group (364 patients and the normal coronary artery group (236 patients- depending on the coronary angiographic findings. Lipid profiles (total cholesterol, Triglyceride, HDL-cholesterol, LDLcholesterol were obtained and the odd ratio of CAD was evaluated according to the national cholesterol education program treatment guideline (NCEP：LDL cholesterol≥130 mg/dl and the national heath insurance treatment guideline (NHI：total cholesterol≥220 mg/dl by multi-variate logistic regression analysis. Results： According to the NHI and NCEP guidelines, the proportion of patients with CAD indicated on cholesterol-lowering therapy were 25%, and 36.5%, respectively, and the odd ratio of CAD was 1.00 (95% CI 0.52-1.89, p ＝0.99, and 4.89 (95% CI 2.78-8.60, p<0.01, respectively. Conclusions：Our data showed that an LDLcholesterol≥130 mg/dl only reflected the risk of CAD in both guidelines, and that a greater proportion of patients was indicated on cholesterol-lowering therapy in the NCEP guideline than in the NHI guideline.

Back‐stepping stabilization of fractional‐order triangular system with applications to chaotic systems

This paper addresses the stabilization of fractional‐order nonlinear lower triangular systems and applies the obtained results to the synchronization of fractional‐order chaotic systems (FOCSs). Three cases are considered as follows: (i) FOCSs have a lower triangular structure themselves. (ii) FOCSs can be converted into the form in full by appropriate nonsingular coordinate transformations. (iii) FOCSs can be transformed into the structure in part by the conversions. It is shown that the above three cases combining with back‐stepping approach are useful for the control of FOCSs. Different from the previous literature, the system structure studied is more concise with more applications. A numerical example is presented to show the validity of the proposed results.
Thermal management of the through silicon vias in 3-D integrated circuits

The through silicon via technology is a promising and preferred way to realize the reliable interconnection for 3-D integrated circuit integration. However, its size and the property of the filled-materials are two factors affecting the thermal behavior of the integrated circuits. In this paper, we design 3-D integrated circuits with different through silicon via models and analyze the effect of different material-filled through silicon vias, aspect ratio and thermal conductivity of the dielectric on the steady-state temperature profiles. The results presented in this paper are expected to aid in the development of thermal design guidelines for through silicon vias in 3-D integrated circuits.
Thermal Characteristics of a Stratospheric Airship with Natural Convection and External Forced Convection

Though convective heat transfer is one of the main factors that dominate the thermal characteristics of stratospheric airships, there is no specific correlation equations for the calculation of convective heat transfer of airships. The equations based on flat plate and sphere models are all in use. To ameliorate the confusing situation of diverse convective heat transfer equations and to end the misuse of them in the thermal characteristic analysis of stratospheric airships, a multinode steady-state model for ellipsoid airships is built. The accuracy of the five widely accepted equations for natural convective heat transfer is compared and analysed on the proposed large-scale airship model by numerical simulation, so does that of the five equations for external forced convective heat transfer. The simulation method is verified by the available experimental data. Simulation results show that the difference of the five natural convection equations is negligible, while that of the five external forced convection equations must be considered in engineering. Forced convection equations with high precision and wide application should be further investigated.
