description: A universe without weak interactions is constructed that undergoes big-bang nucleosynthesis, matter domination, structure formation, and star formation. The stars in this universe are able to burn for billions of years, synthesize elements up to iron, and undergo supernova explosions, dispersing heavy elements into the interstellar medium. These definitive claims are supported by a detailed analysis where this hypothetical "Weakless Universe" is matched to our Universe by simultaneously adjusting Standard Model and cosmological parameters. For instance, chemistry and nuclear physics are essentially unchanged. The apparent habitability of the Weakless Universe suggests that the anthropic principle does not determine the scale of electroweak breaking, or even require that it be smaller than the Planck scale, so long as technically natural parameters may be suitably adjusted. Whether the multi-parameter adjustment is realized or probable is dependent on the ultraviolet completion, such as the string landscape. Considering a similar analysis for the cosmological constant, however, we argue that no adjustments of other parameters are able to allow the cosmological constant to raise up even remotely close to the Planck scale while obtaining macroscopic structure. The fine-tuning problems associated with the electroweak breaking scale and the cosmological constant therefore appear to be qualitatively different from the perspective of obtaining a habitable universe.

description: The comparison of current image data with existing 3D model data of a scene provides an efficient method to keep models up to date. In order to transfer information between 2D and 3D data, a preliminary co-registration is necessary. In this paper, we present a concept to automatically co-register aerial imagery and untextured 3D model data. To refine a given initial camera pose, our algorithm computes dense correspondence fields using SIFT flow between gradient representations of the model and camera image, from which 2D–3D correspondences are obtained. These correspondences are then used in an iterative optimization scheme to refine the initial camera pose by minimizing the reprojection error. Since it is assumed that the model does not contain texture information, our algorithm is built up on an existing method based on Average Shading Gradients (ASG) to generate gradient images based on raw geometry information only. We apply our algorithm for the co-registering of aerial photographs to an untextured, noisy mesh model. We have investigated different magnitudes of input error and show that the proposed approach can reduce the final reprojection error to a minimum of 1.27 ± 0.54 pixels, which is less than 10% of its initial value. Furthermore, our evaluation shows that our approach outperforms the accuracy of a standard Iterative Closest Point (ICP) implementation.

description: We present a new algebraic algorithmic scheme to solve {\em convex integer maximization} problems of the following form, where $c$ is a convex function on $R^d$ and $w_1x,...,w_dx$ are linear forms on $R^n$, $$\max \{c(w_1 x,...,w_d x): Ax=b, x\in N^n\} .$$ This method works for arbitrary input data $A,b,d,w_1,...,w_d,c$. Moreover, for fixed $d$ and several important classes of programs in {\em variable dimension}, we prove that our algorithm runs in {\em polynomial time}. As a consequence, we obtain polynomial time algorithms for various types of multi-way transportation problems, packing problems, and partitioning problems in variable dimension.

description: With the fast development of medical image devices and technologies, the amount of medical image data has increased significantly at a unprecedented rate. In many clinical specialities, there can be a shortage of doctors and radiologist experts to give timely diagnosis and referral to patients when facing the large amount of medical images and data. Especially for the ophthalmology, the widespread availability of optical coherence tomography (OCT), which is a novel medical imaging technology that allow acquisition of cross-sectional images of the retina with semihistologic resolution, has not been matched by the availability of human experts to interpret scans and provide appropriate treatments. According to the National Reporting and Learning System (NRLS), there are about 250 cases of sight harm due to the diagnosis delay per year in UK. Hence, how can we improve the efficiency of clinical diagnosis is a urgent problem need to be solved.In this dissertation, we are going to present a method for classifying normal, diabetic retinopathy (DR) and age-related macular degeneration (AMD) on OCT scan sequences. Different from classic medical image classification problems, OCT is a crosssectional image sequences of eye fundus. The lesions of DR and AMD can be spatial related among OCT slices. To solve this problem and find the feature connection between OCT slices, we proposed a model that contains two neural networks. The first model is a residual neural network, which is used for extract symptom features on each OCT slices. The feature extract from each slices are combined to a series feature as the second model input. The second model is a long short-term memory neural network used for get the predictions based on OCT sequence feature. The model was trained and tested on around 1700 OCT scans, each of them has 25 slice images (Total 36149 slices). We used cross-entropy loss and k-cross validation. The result shows it has a accuracy of 1, 1, 1 on three class, respectively, when choosing the best model.

description: The influence of the medium on the gravitational deflection of light rays is widely discussed in literature for the simplest non-trivial case: cold non-magnetized plasma. In this article, we generalize these studies to the case of an arbitrary transparent dispersive medium with a given refractive index. We calculate the deflection angle of light ray moving in a general spherically symmetric metric in the presence of medium with the spherically symmetric refractive index. The equation for the radius of circular light orbits is also derived. We discuss in detail the properties of these results and various special cases. In particular, we show that multiplying the refractive index by a constant does not affect the deflection angle and radius of circular orbits. At the same time, the presence of dispersion makes the trajectories different from the case of vacuum even in spatially homogeneous medium. As one of the applications of our results, we calculate the correction to the angle of vacuum gravitational deflection for the case when a massive object is surrounded by homogeneous but dispersive medium. As another application, we present the calculation of the shadow of a black hole surrounded by medium with arbitrary refractive index. Our results can serve as a basis for studies of various plasma models beyond the cold plasma case.

Physical work capacity evaluation in vocational rehabilitation and its effect on the vocational placement of disabled male workers
Creators: name: Cooke, Christopher
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to examine the effect of program type and selected predictor variables on the vocational placement and feelings of self-esteem of disabled male workers. It was predicted that: (1) a physical capacity assessment program (PCA), designed by the investigator, would result in a higher rate of successful vocational placement than conventional placement techniques, in a shorter period of time and with a better vocational match; (2) increased measures of self-esteem would be experienced by the PCA group and at a more significant level than conventional vocational programs; (3) there would not be a significant interaction between the vocational placement variables and the independent variables of age, degree of disability and injury type; and (4) there would not be a significant effect of selected moderator variables between groups on the vocational placement variables. Fifty disabled workers were randomly selected from the active caseloads of the Vocational Rehabilitation Department of the Workers' Compensation Board of British Columbia for participation in the study. Their average age was 33.32 years, and their average length of time on wage loss was 245 days. All subjects were injured as the result of an industrial accident, were no longer undergoing medical treatment, had been cleared for a return to work but were suffering from a residual disability that prevented them from returning to the work force. Subjects were randomly assigned to one of two treatment conditions involving vocational counselling with job search training (JS) and vocational counselling with physical capacity assessment (PCA). Following completion of the program, subjects began job search activities and were monitored for a period of 6 months or until successful vocational placement was achieved. Data analyses showed that: there was a significant main effect between groups for success in vocational placement with PCA placing more subjects than job search; there were no significant differences between groups on measures of self-esteem following completion of the programs; there was a significant interaction effect of age, degree of disability and type of injury with success in vocational placement and; there was a significant interaction effect of several moderator variables including marital status and length of time on wage loss with success in vocational placement and time to vocational placement. The results tend to support the use of physical capacity assessment for the guantification of individual capacity to perform work. Further, the results suggest that the use of PCA information in the identification and selection of appropriate vocational alternatives can significantly enhance the success of vocational placement disabled workers. Recommendations were made for future research.

description: Active galactic nuclei come in many varieties. A minority of them are radio-loud, and exhibit two opposite prominent plasma jets extending from the proximity of the supermassive black hole up to megaparsec distances. When one of the relativistic jets is oriented closely to the line of sight, its emission is Doppler beamed and these objects show extreme variability properties at all wavelengths. These are called "blazars". The unpredictable blazar variability, occurring on a continuous range of time-scales, from minutes to years, is most effectively investigated in a multi-wavelength context. Ground-based and space observations together contribute to give us a comprehensive picture of the blazar emission properties from the radio to the gamma-ray band. Moreover, in recent years, a lot of effort has been devoted to the observation and analysis of the blazar polarimetric radio and optical behaviour, showing strong variability of both the polarisation degree and angle. The Whole Earth Blazar Telescope (WEBT) Collaboration, involving many tens of astronomers all around the globe, has been monitoring several blazars since 1997. The results of the corresponding data analysis have contributed to the understanding of the blazar phenomenon, particularly stressing the viability of a geometrical interpretation of the blazar variability. We review here the most significant polarimetric results achieved in the WEBT studies.

description: For hidden Markov models one of the most popular estimates of the hidden chain is the Viterbi path -- the path maximising the posterior probability. We consider a more general setting, called the pairwise Markov model (PMM), where the joint process consisting of finite-state hidden process and observation process is assumed to be a Markov chain. It has been recently proven that under some conditions the Viterbi path of the PMM can almost surely be extended to infinity, thereby defining the infinite Viterbi decoding of the observation sequence, called the Viterbi process. This was done by constructing a block of observations, called a barrier, which ensures that the Viterbi path goes trough a given state whenever this block occurs in the observation sequence. In this paper we prove that the joint process consisting of Viterbi process and PMM is regenerative. The proof involves a delicate construction of regeneration times which coincide with the occurrences of barriers. As one possible application of our theory, some results on the asymptotics of the Viterbi training algorithm are derived.

description: We present a simple experiment that allows us to demonstrate graphically that the intensity of sound waves is proportional to the square of their amplitude, a result that is theoretically analysed in any introductory wave course but rarely demonstrated empirically. To achieve our goal, we use an audio signal generator that, when connected to a loudspeaker, produces sine waves that can be easily observed and measured using an oscilloscope. The measurements made with these instruments allow us to create a plot of amplitude versus sound intensity level, which verifies the mathematical relationship between amplitude and intensity mentioned above. Among the experimental errors, the plot obtained is in excellent agreement with what is theoretically expected.

The effect of non-framework cation mixing on spinel crystallization in iron-rich high-level nuclear waste glasses

description: The vitrification of high Fe, Ni, Mn, and Cr containing nuclear waste faces the problem of the crystallization of spinel in the melter cold cap that poses a threat to the melter's efficiency and brings down the volumetric efficiency of the vitrified waste. Understanding the mechanisms driving the nucleation and crystal growth of spinels in HLW glasses is a vital subject in the vitrification of nuclear waste that is fostered by several environmental and economic reasons. The research focuses on understanding the relationship between alkali/alkaline-earth cations with iron redox, glass structure, and spinel crystallization tendency in the glass compositions of the xLi2O(or CaO)-(25-x)Na2O-9.12B2O3-6.4Al2O3-51.25SiO2-7.22Fe2O3-0.38MnO-0.08Cr2O3-0.55NiO system. Glass compositions of the system mentioned above with varying Li2O/Na2O and CaO/Na2O ratios were synthesized using two different approaches - (1) quenching the melt from 1450 °C between two copper plates in order to understand the structure and crystallization behavior of melts in the HLW melter during operation at 1150 °C, (2) allowing the melt at 1450 °C to cool down to 950 °C followed by isothermal heating at 950 °C for 48 h in order to emulate melter idling. While the modifier cation field strength is reported to affect the NBO distribution substantially, the cation charge and size are also found to affect the Al and B differently. X-ray diffraction, infrared spectroscopy, density measurement, differential scanning calorimetry, and vibration sample magnetometry were used along with optical basicity and Mössbauer spectroscopy to explore the effects of the cation with higher-field strength on the possible evolution of NBOs in the structure, the tendency of iron to enter the crystallization field, the phases formed, etc., Differential scanning calorimetry along with Rietveld analysis was used to understand the crystalline phases. Spinel crystallization is found to decrease with higher basicity and higher Fe3+ concentration of the system. With the introduction of cations with higher field strength, the optical basicity reduces Fe2+ increases, and the tendency to crystallize spinel increases. Vibration sample magnetometry, scanning electron microscopy, and elemental dispersive spectroscopy have been used to understand the size, shape, nature, and distribution of the crystallized phases.
PHASES OF THE FERROMAGNETIC POTTS MODEL WITH FIVE STATES ON A FIRST-ORDER BETHE LATTICE

description: The Ferromagnetic Potts model with five states on a first-order Bethe lattice is a significant subject in statistical physics and mathematical modeling. This abstract explores the distinct phases exhibited by this model and their implications. The Potts model is a lattice-based statistical mechanics model that generalizes the Ising model to systems with more than two possible states at each lattice site. In this study, we focus on the ferromagnetic variant of the Potts model with five states, which is particularly interesting due to its richer phase behavior. Utilizing the framework of a first-order Bethe lattice, we investigate the phase transitions and critical phenomena exhibited by this model. The Bethe lattice provides a simplified yet powerful structure for studying phase transitions in systems with large coordination numbers.

description: We report the deposition of thin Co$_2$FeSi films by RF magnetron sputtering. Epitaxial (100)-oriented and L2$_1$ ordered growth is observed for films grown on MgO(100) substrates. (110)-oriented films on Al$_2$O$_3$(110) show several epitaxial domains in the film plane. Investigation of the magnetic properties reveals a saturation magnetization of 5.0 $mu_B/f.u.$ at low temperatures. The temperature dependence of the resistivity $rho_{xx}(T)$ exhibits a crossover from a T^3.5 law at T<50K to a T^1.65 behaviour at elevated temperatures. $rho_{xx}(H)$ shows a small anisotropic magnetoresistive effect. A weak dependence of the normal Hall effect on the external magnetic field indicates the compensation of electron and hole like contributions at the Fermi surface.

description: Piezoelectrics interconvert mechanical energy and electric charge and are widely used in actuators and sensors. The best performing materials are ferroelectrics at a morphotropic phase boundary (MPB), where several phases can intimately coexist. Switching between these phases by electric field produces a large electromechanical response. In the ferroelectric BiFeO$_3$, strain can be used to create an MPB-like phase mixture and thus to generate large electric field dependent strains. However, this enhanced response occurs at localized, randomly positioned regions of the film, which potentially complicates nanodevice design. Here, we use epitaxial strain and orientation engineering in tandem - anisotropic epitaxy - to craft a hitherto unavailable low-symmetry phase of BiFeO$_3$ which acts as a structural bridge between the rhombohedral-like and tetragonal-like polymorphs. Interferometric displacement sensor measurements and first-principle calculations reveal that under external electric bias, this phase undergoes a transition to the tetragonal-like polymorph, generating a piezoelectric response enhanced by over 200%, and associated giant field-induced reversible strain. These results offer a new route to engineer giant electromechanical properties in thin films, with broader perspectives for other functional oxide systems.

description: Earth science communities use various ontologies/schemas to describe different kinds of datasets and for different reasons, and there is not an integrated (harmonized) schema for describing all concepts of Earth science. The purpose of this deliverable is to summarize and analyze the results of the surveys conducted in WP15, identify the needs and gaps between communities based also on the results of the user requirements (WP12) and propose strategies for having harmonized metadata, semantics and ontologies.
 The deliverable is organized in three main sections aiming at (a) analyzing the results of the WP15 survey, (b) inspecting how the needs of communities are fulfilled and identifying gaps based on the user requirements and (c) describing general approaches for harmonization/integration of information and how they fit into SCIDIP-ES (and in particular in WP33).
 The first section is the analysis of the WP15 results. Particular focus is given in the part of the survey concerning metadata, semantics and ontologies. The objective is to perform an analysis of the semantic models that are widely used by different communities, in terms of their usability, adoption, configurability, extensibility across different Earth Science domains.
 The second section uses the results of the user requirements analysis (WP12) as a pivot in order to identify if the aforementioned ontologies cover the needs of communities.
 The results of the two previous sections are used for the definition of the strategies to have harmonized metadata, semantics and ontologies, able to satisfy the user needs coping with the different Earth Science domain approaches. For the definition of the strategy, core ontologies as well as extensions and mappings for the Earth Science domain have been investigated.
 The results of this deliverable (the strategy) will be provided as input in T21.8 (Finding Aids Toolkit Development).

description: Software development comprises the use of multiple Third-Party Libraries (TPLs). However, the irrelevant libraries present in software application's distributable often lead to excessive consumption of resources such as CPU cycles, memory, and modile-devices' battery usage. Therefore, the identification and removal of unused TPLs present in an application are desirable. We present a rapid, storage-efficient, obfuscation-resilient method to detect the irrelevant-TPLs in Java and Python applications. Our approach's novel aspects are i) Computing a vector representation of a .class file using a model that we call Lib2Vec. The Lib2Vec model is trained using the Paragraph Vector Algorithm. ii) Before using it for training the Lib2Vec models, a .class file is converted to a normalized form via semantics-preserving transformations. iii) A eXtra Library Detector (XtraLibD) developed and tested with 27 different language-specific Lib2Vec models. These models were trained using different parameters and >30,000 .class and >478,000 .py files taken from >100 different Java libraries and 43,711 Python available at MavenCentral.com and Pypi.com, respectively. XtraLibD achieves an accuracy of 99.48% with an F1 score of 0.968 and outperforms the existing tools, viz., LibScout, LiteRadar, and LibD with an accuracy improvement of 74.5%, 30.33%, and 14.1%, respectively. Compared with LibD, XtraLibD achieves a response time improvement of 61.37% and a storage reduction of 87.93% (99.85% over JIngredient).

description: AIMS: We examine whether ejection phenomena from accreting T Tauri stars can be described by only one type of self-collimated jet model. METHODS: We present analytical kinematic predictions valid soon after the Alfvén surface for all types of steady magnetically self-confined jets. RESULTS: We show that extended disc winds, X-winds, and stellar winds occupy distinct regions in the poloidal speed vs. specific angular momentum plane. Comparisons with current observations of T Tauri jets yield quantitative constraints on the range of launching radii, magnetic lever arms, and specific energy input in disc and stellar winds. Implications on the origin of jet asymmetries and disc magnetic fields are outlined. CONCLUSIONS: We argue that ejection phenomena from accreting T Tauri stars most likely include three dynamical components: (1) an outer self-collimated steady disc wind carrying most of the mass-flux in the optical jet (when present), confining (2) a pressure-driven coronal stellar wind and (3) a hot inner flow made of blobs sporadically ejected from the magnetopause. If the stellar magnetic moment is parallel to the disc magnetic field, then the highly variable inner flow resembles a "Reconnection X-wind", that has been proven to efficiently brake down an accreting and contracting young star. If the magnetic moment is anti-parallel, then larger versions of the solar coronal mass ejections are likely to occur. The relative importance of these three components in the observed outflows and the range of radii involved in the disc wind are expected to vary with time, from the stage of embedded source to the optically revealed T Tauri star phase.

description: Thin films of transition metal oxides open up a gateway to nanoscale electronic devices beyond silicon characterized by novel electronic functionalities. While such films are commonly prepared in an oxygen atmosphere, they are typically considered to be ideally terminated with the stoichiometric composition. Using the prototypical correlated metal SrVO$_3$ as an example, it is demonstrated that this idealized description overlooks an essential ingredient: oxygen adsorbing at the surface apical sites. The oxygen adatoms, which persist even in an ultrahigh vacuum environment, are shown to severely affect the intrinsic electronic structure of a transition metal oxide film. Their presence leads to the formation of an electronically dead surface layer but also alters the band filling and the electron correlations in the thin films. These findings highlight that it is important to take into account surface apical oxygen or -- mutatis mutandis -- the specific oxygen configuration imposed by a capping layer to predict the behavior of ultrathin films of transition metal oxides near the single unit-cell limit.

description: The present study examined psychological factors associated with individual variation in children's adjustment following minor surgery, and focused specifically on the process of coping with postoperative pain. Sixty children and adolescents (7 to 16 yrs) were interviewed on the day following surgery. They provided ratings and descriptions of their postoperative pain experience, perceived capacity for pain control, spontaneous coping strategies, and emotional distress. Parents also provided information about their efforts (both historical and present) to facilitate their child's coping, their own emotional distress, and perceptions of their child's distress following surgery. Thirdly, nurses rated children's pain behaviours displayed on the ward. Finally, information about analgesic medications and physical complications following surgery was recorded from children's medical charts. Qualitative data concerning the process of coping with postoperative pain and specific parental influences on children's coping were presented within a conceptual model adapted from the adult stress and coping literature. The data were also analyzed for age/developmental differences between older children (10 to 16 yrs) and younger children (7 to 9 yrs). Finally the predictive role of demographic, child coping process, and parental influence variables, in accounting for variations in child coping outcome, was analyzed. Results indicated that children and adolescents experienced moderate to severe pain following minor surgery. They reportedly tried a number of different cognitive and behavioural methods to deal with postoperative pain. Also, parents took an active role in facilitating children's coping. Age group differences were revealed in children's descriptions of postoperative pain, their reported ways of coping with pain, and their perceptions of control over pain and recovery. Age effects were interpreted with caution, however, since age and sex were confounded in this sample. Children who reported the most pain and emotional distress following surgery also reported more catastrophizing cognitions, felt less in control of their recovery, and reported having tried a greater number of behavioral coping strategies to manage pain. These results emphasize the role of children's appraisal processes in predicting coping effectiveness, and demonstrate that more coping does not imply better outcome. Future research directions and potential clinical appplications that follow from these findings were discussed.

description: The phase diagram of two-level boson Hamiltonians, including the Interacting Boson Model (IBM), is studied beyond the standard mean field approximation using the Holstein-Primakoff mapping. The limitations of the usual intrinsic state (mean field) formalism concerning finite-size effects are pointed out. The analytic results are compared to numerics obtained from exact diagonalizations. Excitation energies and occupation numbers are studied in different model space regions (Casten triangle for IBM) and especially at the critical points.

description: R E S U M OAs unidades de conservação são espaços destinados à proteção dos recursos naturais no ambiente urbano. Apesar de sua importância, essas unidades sofrem constantes perturbações, principalmente por queimadas (incêndios), que trazem efeitos negativos à saúde do ecossistema e dos moradores próximos. Nesse contexto, este estudo teve como objetivo analisar áreas queimadas por meio de imagens Sentinel-2 no Parque Estadual do Cocó (PEC), Região Metropolitana de Fortaleza. Foram utilizadas técnicas de sensoriamento remoto e índices espectrais (NBR e NDVI) derivados de imagens Sentinel-2, em período anterior e posterior a uma queimada no PEC em novembro de 2021. Foi obtida uma área queimada de 45,55 ha, localizada na parte oeste do PEC, e foi identificada uma diminuição na refletância da vegetação de 29,14%, bem como uma severidade moderada-alta e moderada-baixa para NBR e NDVI de 41,7% e 33,6% respectivamente da área queimada. Por outro lado, a série temporal mostrou uma mudança na cobertura vegetal para solo descoberto um ano após o evento, o que demonstrou a dinâmica da vegetação após a queimada. Esses resultados apresentam um precedente no uso do sensoriamento remoto para o estudo de áreas queimadas na região de Fortaleza, especificamente na área do PEC, o que poderia ser uma ferramenta de apoio aos tomadores de decisão na gestão, restauração de áreas com altos níveis de degradação e conservação do patrimônio ambiental do nordeste brasileiro.Palavras-Chaves: Fogo.

description: Effectiveness of teaching digital signal processing can be enhanced by reducing lecture time devoted to theory, and increasing emphasis on applications, programming aspects, visualization and intuitive understanding. An integrated approach to teaching requires instructors to simultaneously teach theory and its applications in storage and processing of audio, speech and biomedical signals. Student engagement can be enhanced by engaging students to work in groups during the class where students can solve short problems and short programming assignments or take quizzes. These approaches will increase student interest in learning the subject and student engagement.

description: This review paper identifies the core evidence of research on employee engagement , considering a stern challenge facing the financial sector nowadays. The study highlights the noteworthy knowledge gaps that will support human resource management practitioners to embed in the research towards sectoral context. Pertinent articles were selected through key search points and excerpt-related literature. The key search points covered the topic related to different terms of engagement for example "employee engagement" OR "work engagement" OR "job engagement" OR "organization engagement" OR "staff engagement" OR "personnel engagement" which were steered in diverse context particularly financial sector. Through critically reviewing the literature for the last 11 years i.e., 2009-2019, we discovered 91 empirical studies in financial sector. From these studies, we found the overall concept of engagement and its different determinants (e.g., organizational factors, individual factors, job factors) as well as its various outcomes (e.g., employee outcomes, organizational outcomes). We also formulated a conceptual model to expand the body of knowledge in the area of employee engagement for a better understanding of its predictors and outcomes. Besides, limitations of the study and future recommendations are also contemplated.

description: If heavy partners of the Standard Model matter fields are discovered at the LHC it will be imperative to determine their spin in order to uncover the underlying theory. In decay chains, both the spin and the mass hierarchy of all particles involved can influence the resulting angular correlations. We present the necessary conditions for decays involving the matter partners to exhibit angular correlations. In particular we find that when the masses are not degenerate, a heavy fermionic sector always displays angular correlations in cascade decays. When the masses are closely degenerate the size of spin effects is controlled by a global phase parameter. In a large region of the parameter space, correlations are strongly suppressed. In other regions, such as in UED model where this phase is fixed by 5-d Lorentz invariance, the correlations are pronounced. In addition, we show that in certain cases one may even have enough information to determine the spin of other heavy partners involved in the decay (such as the Lightest Stable Partner or a heavy gluon).

description: Glucose biosensors play an important role in the diagnosis and continued monitoring of the disease, diabetes mellitus. This report proposes the development of a novel enzymatic electrochemical glucose biosensor based on TiO$_2$ nanotubes modified by AgO and Prussian blue (PB) nanoparticles (NPs), which has an additional advantage of possessing antimicrobial properties for implantable biosensor applications. In this study, we developed two high performance glucose biosensors based on the immobilization of glucose oxidase (GOx) onto Prussian blue (PB) modified TiO$_2$ nanotube arrays functionalized by Au and AgO NPs. AgO-deposited TiO$_2$ nanotubes were synthesized through an electrochemical anodization process followed by Ag electroplating process in the same electrolyte. Deposition of PB particles was performed from an acidic ferricyanide solution. The surface morphology and elemental composition of the two fabricated biosensors were investigated by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) which indicate the successful deposition of Au and AgO nanoparticles as well as PB nanocrystals. Cyclic voltammetry and chronoamperometry were used to investigate the performance of the modified electrochemical biosensors. The results show that the developed electrochemical biosensors display excellent properties in terms of electron transmission, low detection limit as well as high stability for the determination of glucose. Under the optimized conditions, the amperometric response shows a linear dependence on the glucose concentration to a detection limit down to 4.91 $μ$M with sensitivity of 185.1 mA M$^{-1}$ cm$^{-2]$ in Au modified biosensor and detection limit of 58.7 $μ$M with 29.1 mA M$^{-1}$ cm$^{-2]$ sensitivity in AgO modified biosensor.
