description: We present a comprehensive and detailed study of the stellar populations of the Fornax dwarf spheroidal galaxy. We analyse their spatial distributions along the main body of the galaxy, obtaining their surface density maps, together with their radial density profiles. Results are based on the largest and most complete catalogue of stars in Fornax, with more than $3.5\times10^{5}$ stars covering the main body of the galaxy up to $V \sim 24$. We find a differentiated structure in Fornax depending on the stellar ages. Old stars ($\gtrsim 10$ Gyr) follow an elliptical distribution well fitted by King profiles with relatively large core radius ($r_{\rm c} = 760\pm60$ pc). On another hand, young populations ($\lesssim 3$ Gyr) concentrate in the central region of the galaxy ($r_{\rm c} = 210\pm10$ pc), and are better fitted by Sersic profiles with $0.8 < n < 1.2$, indicating some discy shape. These stars show strong asymmetries and substructures not aligned with the main optical axes of Fornax. This together with the observed differences between metallicity and age distribution maps strongly suggests accretion of material with different angular momentum. These results lead us to propose a scenario in which Fornax has suffered a major merger at $z\sim1$.

The Occupational and Environmental Health Nurses’ Role in Providing a Comprehensive Approach to Depression Management
Creators: name: Stiehl, Kristin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Depression is a common condition that impacts all levels of the workforce, often going undiagnosed and untreated due to both individual and organizational barriers. Workers with depression can experience multiple symptoms that contribute to personal suffering as well as impaired job performance resulting in loss of productivity for the organization. Identifying depressed workers can facilitate prompt treatment, reduce symptoms in the worker, improve, productivity, and reduce healthcare costs. Through a comprehensive approach to depression management, the occupational and environmental health nurse (OEHN) can implement strategies to educate the workforce on depression and available treatment, identify workers who are depressed, and make referrals for appropriate treatment. The OEHN can also assist management with identifying job accommodations for modified duty after an episode of worker disability from depression. Modified duty ensures that injured workers are matched with a jobs that accommodate physical capabilities and reduce lost time Keywords: occupational health nursing, depression, modified duty

description: Azobenzene-containing polymer networks are unique compounds that are able to change their shape in response to light, which makes them prospective materials for photocontrollable nano-templates, sensors, microrobots, artificial muscles, etc. In present work, we study the kinetics of light-induced ordering and deformation in two-component polymer networks containing optically inert liquid crystalline (LC) mesogens and azobenzene chromophores. By this, we generalize our previous theory [J. Phys. Chem. Lett. 2017, 8, 1094–1098] devoted to the kinetics of photoizomerization in one-component azo-polymers without mesogenic inclusions. The kinetic equations of photoisomerization are used, taking into account the angular selectivity of the photoisomerization with respect to the polarization direction of the light E. After multiple trans-cis-trans photoisomerization cycles, the azobenzenes are reoriented preferably perpendicular to the vector E. This changes the ordering of the mesogens due to the orientational LC interactions between the components. The light-induced reordering is accompanied by network deformation. Time evolution of ordering and deformation is found as a function of the intensity of light and structural parameters of the LC azo-networks, which define the viscosity, the strength of the LC interactions between the components, the volume fraction of the azobenzene moieties, and the angular distribution of azobenzenes in polymer chains. Established structure-property relationships are in agreement with a number of experimental data.

description: We consider a small cell network (SCN) consisting of N cells, with the small cell base stations (SCBSs) equipped with Nt \geq 1 antennas each, serving K single antenna user terminals (UTs) per cell. Under this set up, we address the following question: given certain time average quality of service (QoS) targets for the UTs, what is the minimum transmit power expenditure with which they can be met? Our motivation to consider time average QoS constraint comes from the fact that modern wireless applications such as file sharing, multi-media etc. allow some flexibility in terms of their delay tolerance. Time average QoS constraints can lead to greater transmit power savings as compared to instantaneous QoS constraints since it provides the flexibility to dynamically allocate resources over the fading channel states. We formulate the problem as a stochastic optimization problem whose solution is the design of the downlink beamforming vectors during each time slot. We solve this problem using the approach of Lyapunov optimization and characterize the performance of the proposed algorithm. With this algorithm as the reference, we present two main contributions that incorporate practical design considerations in SCNs. First, we analyze the impact of delays incurred in information exchange between the SCBSs. Second, we impose channel state information (CSI) feedback constraints, and formulate a joint CSI feedback and beamforming strategy. In both cases, we provide performance bounds of the algorithm in terms of satisfying the QoS constraints and the time average power expenditure. Our simulation results show that solving the problem with time average QoS constraints provide greater savings in the transmit power as compared to the instantaneous QoS constraints.

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In a previous work, we investigated the evolution of the flow field around sunspots during sunspot decay and compared it with the flow field of supergranular cells. The decay of a sunspot proceeds as it interacts with its surroundings. This is manifested by the changes observed in the flow field surrounding the decaying spot. We now investigate in detail the evolution of the flow field in the direct periphery of the sunspots of the same sample and aim to provide a complete picture of the role of large-scale flows present in sunspot cells. We analyse the horizontal velocity profiles of sunspots obtained from observations by the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO). We follow their evolution across the solar disc from their stable phase to their decay and their final disappearance. We find two different scenarios for the evolution of the flow region surrounding a spot in the final stage of its decay: (i) either the flow cell implodes and disappears under the action of the surrounding supergranules or (ii) it outlives the spot. In the later case, an inwards flow towards the remaining naked spot develops in the vicinity closest to the spot followed by an outflow further out. These findings provide observational evidence to theoretical predictions by realistic magnetohydrodynamic (MHD) sunspot and moat region simulations. The Evershed flow and the moat flow, both connected to the presence of fully fledged sunspots in a spot cell, vanish when penumbrae decay. Moat flows decline into supergranular flows. The final fate of a spot cell depends on its interaction with the surrounding supergranular cells. In the case of non-imploding spot cells, the remaining naked spot develops a converging inflow driven by radiative cooling and a geometrical alignment of granules in its periphery which is similar to that observed in pores.

Increasing patient communication by hourly rounding in the emergency department to increase patient safety and satisfaction
Creators: name: Sung, Linda
Publisher: name: No Publisher Supplied
Year: 2023

description: AbstractPurpose of Project:The implementation of hourly rounding by patient care technicians was implemented in an emergency department for all patients. The aim of this quality improvement project was to increase patient safety and satisfaction. The outcome of this intervention should have improved morbidity for patients.Methodology:A retrospective audit was performed in an Emergency Department treating adults, over a period of one month. The data was collected to determine the number of patient falls, the number of patients who left before treatment was complete, and patient satisfaction scores. After the implementation of an educational self-guided training module, patient care technicians conducted hourly rounding on all patients in the unit. After this was performed, the same outcome measures were collected to compare pre-intervention and post-intervention patient safety and satisfaction scores. Results:The data showed hourly rounding decreased the number of patient falls by 20% and the number of patients who left the Emergency Department before treatment was complete by 33.3%. However, the patient satisfaction scores were found to be decreased by 0.71% which was unexpected. Implications for Practice:Hourly rounding by patient care technicians can increase patient safety although the documentation of the rounding remains nonadherent. The improvement in safety is valuable and hourly rounding can serve as a model for other Emergency Departments. Chart audits revealed the patient care technicians did not document their rounding on the patients. However, it was believed by the clinical leadership they were adherent to the hourly rounding, but were not documenting the encounter. The decrease in patient satisfaction was unexpected and unable to be determined if it was clinically significant. This may be due to the increase in patient volume during the post-implementation month or could be more critically ill patients that require more attention and takes away rounding from other patients. Further study on this can be done by auditing charts for another month post-implementation to see if there is a continued decrease in patient satisfaction scores. It would also be beneficial to replicate this project with accurate documentation. Keywords: patient safety, patient satisfaction, hourly rounding, Emergency Department, patient care technicians

description: Carbon nanoparticles tend to form agglomerates with considerable cohesive strength, depending on particle morphology and chemistry, thus presenting different dispersion challenges. The present work studies the dispersion of three types of graphite nanoplates (GnP) with different flake sizes and bulk densities in a polypropylene melt, using a prototype extensional mixer under comparable hydrodynamic stresses. The nanoparticles were also chemically functionalized by covalent bonding polymer molecules to their surface, and the dispersion of the functionalized GnP was studied. The effects of stress relaxation on dispersion were also analyzed. Samples were removed along the mixer length, and characterized by microscopy and dielectric spectroscopy. A lower dispersion rate was observed for GnP with larger surface area and higher bulk density. Significant re-agglomeration was observed for all materials when the deformation rate was reduced. The polypropylene-functionalized GnP, characterized by increased compatibility with the polymer matrix, showed similar dispersion effects, albeit presenting slightly higher dispersion levels. All the composites exhibit dielectric behavior, however, the alternate current (AC) conductivity is systematically higher for the composites with larger flake GnP.

description: The strategy utilizing trastuzumab, a humanized monoclonal antibody against human epidermal growth receptor 2 (HER-2), as a therapeutic agent in HER-2 positive breast cancer therapy seems to have advantage over traditional chemotherapy, especially when given in combination with anticancer drugs. However, the effectiveness of single antibody or antibody conjugated with chemotherapeutics is still far from ideal. Antibody–dendrimer conjugates hold the potential to improve the targeting and release of active substance at the tumor site. In the present study, we developed and synthesized PAMAM dendrimer–trastuzumab conjugates carrying doxorubicin (dox) specifically to cells overexpressing HER-2. 1HNMR, FTIR and RP-HPLC were used to characterize the products and analyze their purity. Toxicity of PAMAM–trastuzumab and PAMAM–dox–trastuzumab conjugates compared with free trastuzumab and doxorubicin towards HER-2 positive (SKBR-3) and negative (MCF-7) human breast cancer cell lines was determined using MTT assay. Furthermore, the cellular uptake and cellular localization were studied by flow cytometry and confocal microscopy, respectively. A cytotoxicity profile of above mentioned compounds indicated that conjugate PAMAM–dox–trastuzumab was more effective when compared to free drug or the conjugate PAMAM–trastuzumab. Moreover, these results reveal that trastuzumab can be used as a targeting agent in PAMAM–dox–trastuzumab conjugate. Therefore PAMAM–dox–trastuzumab conjugate might be an interesting proposition which could lead to improvements in the effectiveness of drug delivery systems for tumors that overexpress HER-2.

Chronic Disease in the Developing World: The Emergence of a Global Threat

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Since the turn of the century, tremendous strides have been made in public health practices throughout the world to control death and disability related to communicable diseases. The development of vaccines, the introduction of antibiotics, improvements in maternal and infant care and improvements in public sanitation, have all served to lower mortality rates related to communicable diseases. This trend has been especially true in high-income countries, but has also occurred in low to middle income countries. Coupled with this trend has been the emergence of chronic diseases, or noncommunicable disease, as an increasing threat to the health and well being of the developing world. These diseases are characterized by a long latency period, a mixture of casual factors including well-known risk factors, a prolonged course of illness, a noncontagious origin, functional impairment and incurability. Cardiovascular disease, diabetes, cancer, strokes and chronic pulmonary disease have now become the most common causes of death worldwide except in sub-Saharan Africa and the Middle East. If this rate continues at its current pace, by the year 2020 non-communicable disease will account for 80% of the global burden of disease, causing seven out of ten deaths in developing countries. Once thought to be the scourge of the developed, "westernized" world, chronic disease is now the largest cause of mortality in the developing world and will only continue to escalate unless significant interventions are implemented at both the individual and population level. This development is of major significance in low to middle income countries because they are ill prepared to respond to this threat through either prevention or treatment. They lack the health infrastructure to both provide care under the increasing pressure that will be placed on their delivery systems and their public health capabilities are not sufficiently developed to implement programs that will address the underlying determinants of this growing problem. There will also be financial consequences that develop as a result of the impact of this illness burden on a country's workforce and macroeconomic development. Heart disease, diabetes and stroke, for example, are estimated to reduce the gross domestic product by 1 to 5% per year in low to middle income countries. The combination of lower birth rates and increasing life expectancy in developing countries will increase that segment of the population that is susceptible to chronic disease. This increases the importance of crafting appropriate strategies and programs to respond to this growing problem. This paper will present an overview of the extent of the problem, explore the determinants behind the rise in non-communicable disease and discuss possible solutions. While there will be discussion of the global consequence of this problem, the focus will be on Latin American countries.

Relativistic Bohmian mechanics without a preferred foliation

description: In non-relativistic Bohmian mechanics the universe is represented by a probability space whose sample space is composed of the Bohmian trajectories. In relativistic Bohmian mechanics an entire class of empirically equivalent probability spaces can be defined, one for every foliation of spacetime. In the literature the hypothesis has been advanced that a single preferred foliation is allowed, and that this foliation derives from the universal wave function by means of a covariant law. In the present paper the opposite hypothesis is advanced, i.e., no law exists for the foliations and therefore all the foliations are allowed. The resulting model of the universe is basically the "union" of all the probability spaces associated with the foliations. This hypothesis is mainly motivated by the fact that any law defining a preferred foliation is empirically irrelevant. It is also argued that the absence of a preferred foliation may reduce the well known conflict between Bohmian mechanics and Relativity.

Current Issues and Trends in Comparative Effectiveness Research
Creators: name: Singler, Lindsay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Comparative Effectiveness Research (CER) has received national attention in recent years and since the passage of the American Recovery and Reinvestment Act of 2009 as a way to improve health outcomes and reduce healthcare spending. This paper explores current trends and issues in CER, and illustrates the use and future potential of CER through a recent case study. According to the Institute of Medicine, CER is the generation and synthesis of evidence that compares the benefits and harms of alternative methods to prevent, diagnose, treat, and monitor a clinical condition or to improve the delivery of care (Sox, 2010). Simply put, the purpose of CER is to help patients and their healthcare providers, especially physicians, make better-informed healthcare decisions. CER embraces the concept of patient-centeredness by ensuring the right treatment for the right patient at the right time (Biskupiak et al., 2012). It has potential to not only improve individual patient outcomes, but also population health through the use of evidence to recommend care guidelines and standards. By making healthcare more efficient and effective, it is also thought that CER can reduce healthcare spending. It is anticipated that healthcare payers, providers, biopharmaceutical companies, medical device companies and patients all have great benefits to reap from CER. The Patient-Centered Outcomes Research Institute (PCORI), which was established as an independent non-profit corporation in 2010 by the Patient Protection and Affordable Care Act, is a driving force behind recent interest and support of CER, and has funded high-profile studies. This paper reviews the benefits of CER as a methodology to compare treatment options by synthesizing existing evidence or generating new evidence to inform decision-making. It illustrates these benefits though a currently ongoing, PCORI funded, uterine fibroids case study. It also provides a brief overview of some of the many ways to perform CER, emphasizing consideration of the research question at hand to select the most effective method for assessing comparative effectiveness. Finally, it briefly reviews benefits and criticisms of CER and identifies areas for further discussion. An important conclusion is that the future of CER is about making research more patient-friendly, useful and scientifically credible. To do so, continued collaboration is needed between all healthcare stakeholders - most importantly - patients. In this way, CER can play an important role to achieve national goals of reduced healthcare spending and improved health outcomes.

Global Alliances: Steps to Self-Sustainability for the Good of Public Health
Creators: name: Poe, Carolyn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Creating global alliances to fight disease and build infrastructure in developing and middle income countries has become a popular topic in the last several years. The global burden of disease and disparities in the level of health and healthcare make it difficult for any one group or funding source to make significant improvements in these areas, and in many areas of the world, the infrastructure simply does not exist. Global alliances have been instrumental in helping to build this infrastructure and research capacity, thereby reducing the impact of IDV/ AIDS, TB, malaria, and many other diseases. The ultimate goal of building sustainable capacity and infrastructure is to facilitate the transfer of knowledge gained through research into clinical practice and policy but it is a complex, resource-intensive process with many challenges. In 2005, the threat of an influenza pandemic led the National Institutes of Health and the Wellcome Trust to form the Southeast Asia Influenza Clinical Trial Network, supported by Oxford University and Family Health International. Although much progress has been made in a short time, challenges persist and the long term benefits have yet to be established.

description: An analytical study on the nave mural paintings of the church “The Nativity of the Virgin” of Rila monastery, Bulgaria, painted by Zahari Zograph was carried out. Vibrational spectroscopy was applied to identify the pigments and organic materials used in the mural paintings. To complement the spectral information, elemental composition of the samples was determined by SEM-EDX. The data showed that smalt with carbohydrate binder was applied for the blue background, green colour was executed by green earths and red-orange colour – by red lead. Azurite is the pigment used to paint the blue colour of the saints’ hoods. The mordant for gilding was prepared of drying oil, resin and siccative metal oxides as evidenced by SEM-EDX, ATR-FTIR and pyrolysis GC-MS analysis. The use of azurite is related to Zahari Zograph’s works as it was not found in any of the previously studied murals in the church painted by other artists.
Elderly Trauma in Sub-Saharan Africa

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The world is aging rapidly but it is unclear how the world's growing older population will affect health care systems in low or middle-income countries. One area of concern is traumatic injury, which is endemic at all ages, with older patients suffering worse outcomes compared to younger patients. Consequently, traumatic injury in the elderly is an emerging public health issue in resource-poor environments. Unfortunately, there is a dearth of data on the characteristics and extent of this problem in sub-Saharan Africa. This study has two aims. First, it will describe what data are available on elderly trauma in sub-Saharan Africa and access the quality of published studies. Second, it will describe the characteristics and outcomes of traumatic injury in the elderly from a tertiary trauma center in sub-Saharan Africa.
Decreasing door-in-door-out times for acute stroke patients at primary stroke centers

description: AbstractPurpose of the Project: The project evaluated the effectiveness of early activation of transport and imaging timeliness of Door-In-Door-Out (DIDO) transfer times for acute stroke patients at three NJ primary stroke centers. Staff perceptions of barriers to DIDO were analyzed.Methodology: The population included surveys from 85 team members on barriers to a 90-minute DIDO. The AHA recommends that 50% of patients achieve a DIDO of 90 minutes. There were 375 medical records included of stroke patients reviewed in the project.Results: This project concluded that early transport mobilization activation within 15 minutes of arrival significantly affects DIDO times. A Mann Whitney U test revealed statistical significance between Intercranial hemorrhage (ICH) and acute ischemic stroke (AIS) (H = -2.606, p = .009) and between subarachnoid hemorrhage (SAH) and AIS (H = -2.928, p = .003). When stroke activation code was used within 15 minutes for AIS patients, 67% at one site achieved a DIDO within 90 minutes. RAPID software to identify large vessel occlusion occurred 38 minutes sooner than radiology reads. Surveys revealed many staff members were not aware of the DIDO goals and many reported they were not satisfied with the education provided. Surveys revealed eight reported delays, including transport time and waiting for accepting provider.Implications for Practice: Education for all areas involved in the transfer of these patients is necessary for improving awareness of DIDO goals. Reviews on SAH recognition and an activation protocol specific to this population should be developed. CSNI activation should be triggered within 15 minutes. Use of RAPID software should be fully employed.Keywords: Door-In-Door-Out (DIDO), transfer, stroke, subarachnoid hemorrhage, intracerebral hemorrhage, acute ischemic stroke, large vessel occlusion (LVO), RAPID software, neurosurgery, transport delay

description: XAFS studies of Ni-doped Ba$_{1-x}$Sr$_x$TiO$_3$ solid solution reveal that the Ni oxidation state changes from 4 in SrTiO$_3$ to 2.5 in BaTiO$_3$ when varying $x$. This change is accompanied by a noticeable change in the interatomic Ni-O distances in the first shell. The first-principles calculations show that nickel creates an impurity band in the forbidden band gap of BaTiO$_3$ and SrTiO$_3$, which explains the appearance of intense absorption of Ni-doped samples in the visible region. The analysis of the electronic structure of doped crystals and calculations of the oxygen vacancy formation energy in them show that different oxidation states of Ni in SrTiO$_3$ and BaTiO$_3$ can be explained by different formation energies of the oxygen vacancies in these compounds.

description: BACKGROUND: The Ticket to Work-Work Incentives Improvement Act was designed to help adults receiving Social Security disability return to work and stop receiving benefits. Little data are available to tell us how successful this program has been in reaching these aims, and no data at all inform us about how this program has affected adults with psychiatric disabilities. METHODS: I interviewed Ticket to Work administrators in seven states with high levels of program enrollment to learn more about variables that affect the success of the program. RESULTS: The interviews confirm that only some states are collecting outcomes data for adults with psychiatric disabilities. Mental health and vocational rehabilitation collaboration was a common theme for these policymakers, as was the importance of benefits counseling. CONCLUSIONS: Improving vocational rehabilitation and mental health coordination and creating stronger links between the Ticket to Work (TTW) and Work Incentives Planning and Assistance (WIPA) programs are potential interventions that could improve the success of the program for this particular population.

description: A major challenge in the development of a fully automated vehicle is to enable a large variety of users to use the vehicle independently and safely. Particular demands arise from user groups who rely on human assistance when using conventional cars. For the independent use of a vehicle by such groups, the vehicle must compensate for the absence of an accompanying person, whose actions and decisions ensure the accompanied person's safety even in unknown situations. The resulting requirements cannot be fulfilled only by the geometric design of the vehicle and the nature of its control elements. Special user needs must be taken into account in the entire automation of the vehicle. In this paper, we describe requirements for compensating for the absence of an accompanying person and show how required functions can be located in a hierarchical functional system architecture of an automated vehicle. In addition, we outline the relevance of the vehicle's operational design domain in this context and present a use case for the described functionalities.

Recommendations for the Development of an Advocacy Campaign for Public Act 653’06-Michigan’s Health Disparity Law

description: In the history of the United Sates, the general health outcomes of minority populations have never equaled the health status of Caucasians. The nation’s general life expectancies and the overall health status have improved dramatically for all Americans in the last six decades. However, excess morbidity and the decreased life expectancy in the general health of minority populations have proved to be stubbornly resistant to improvement. Minority populations in Michigan are needlessly suffering and dying prematurely due to social inequities that manifest themselves as disparate health outcomes. The Michigan legislature passed Public Act 653’06 - the Health Disparities Research and Education Act in 2007 to address this deplorable situation. The law was passed, however, without the appropriate funding, infrastructure, and possibly intent to address the health disparity issue. This paper calls for the creation of a public health advocacy campaign to inform the general public about health disparities, impact public opinion, and ultimately gain the attention of the legislature who can make implementation of Public Act 653’06 a reality.

description: The most effective way to achieve very high collision energies in a circular particle accelerator is to maximize the field strength of the main bending dipoles. In dipole magnets using Nb-Ti superconductor the practical field limit is considered to be 8-9 T. When Nb3Sn superconductor material is utilized, a field level of 15-16 T can be achieved. To further push the magnetic field beyond the Nb3Sn limits, High Temperature Superconductors (HTS) need to be considered in the magnet design. The most promising HTS materials for particle accelerator magnets are Bi2212 and REBCO. However, their outstanding performance comes with a significantly higher cost. Therefore, an economically viable option towards 20 T dipole magnets could consist in an hybrid solution, where both HTS and Nb3Sn materials are used. We discuss in this paper preliminary conceptual designs of various 20 T hybrid magnet concepts. After the definition of the overall design criteria, the coil dimensions and parameters are investigated with finite element models based on simple sector coils. Preliminary 2D cross-section computation results are then presented and three main layouts compared: cos-theta, block, and common-coil. Both traditional designs and more advanced stress-management options are considered.

description: Casein is the major protein fraction in milk, and its cross-linking has been a topic of scientific interest for many years. Enzymatic cross-linking has huge potential to modify relevant techno-functional properties of casein, whereas non-enzymatic cross-linking occurs naturally during the storage and processing of milk and dairy products. Two size separation techniques were applied for characterisation of these reactions: gel electrophoresis and size exclusion chromatography. This review summarises their separation principles and discusses the outcome of studies on cross-linked casein from the last ~20 years. Both methods, however, show limitations concerning separation range and are applied mainly under denaturing and reducing conditions. In contrast, field flow fractionation has a broad separation range and can be easily applied under native conditions. Although this method has become a powerful tool in polymer and nanoparticle analysis and was used in few studies on casein micelles, it has not yet been applied to investigate cross-linked casein. Finally, the principles and requirements for absolute molar mass determination are reviewed, which will be of increased interest in the future since suitable calibration substances for casein polymers are scarce.

description: Experimental evidence from both spin-valve and quantum transport measurements points towards unexpectedly fast spin relaxation in graphene. We report magnetotransport studies of epitaxial graphene on SiC in a vector magnetic field showing that spin relaxation, detected using weak-localisation analysis, is suppressed by an in-plane magnetic field, $B_{\parallel}$, and thereby proving that it is caused at least in part by spinful scatterers. A non-monotonic dependence of effective decoherence rate on $B_{\parallel}$ reveals the intricate role of scatterers' spin dynamics in forming the interference correction to conductivity, an effect that has gone unnoticed in earlier weak localisation studies

description: This paper presents a CMOS Radio frequency dielectric sensor platform for the detection of relative viscosity changes in a fluid sample. The operating frequency of the sensor is 12.28 GHz. This frequency range has been chosen for high signal to noise ratio and also to avoid other low frequency dispersion mechanisms for future lab on chip applications. The sensor chip has been fabricated in 250 nm BiCMOS technology of IHP. The measurements conducted to show the relative viscosity variation detection capability of the sensor chip, were based on mixtures of glycerol and water as well as glycerol and organic alcohol. The detection limit of viscosity is dependent on the permittivity contrast of the sample constituent. Therefore, it is also shown the choice of frequency inherently aids in the permittivity contrast of the sample constituents.
