Evaluating the Impact of Double-Parked Freight Deliveries on Signalized Arterial Control Delay Using Analytical Models and Simulation
Creators: name: Keegan, Aaron J.
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Freight deliveries on signalized urban streets are known to cause lane blockages during delivery. Traffic congestion associated with urban freight deliveries has gained increasing attention recently as traffic engineers and planners are tasked with finding solutions to manage increasing demand more sustainably with limited road capacity. The goal of this research is to evaluate two models for quantifying the capacity and signalized control delay effects of a lane-blocking freight delivery on an urban arterial. The two methods are: an All-or-Nothing model similar to methodology used in the Highway Capacity Manual 6th Edition, and a Detailed model consistent with kinematic wave theory. The purpose is to provide insight on the use of these tools for analysis of urban freight delivery. The signalized control delay results of the two models are compared with observed video data of urban deliveries from one city block of 8th Ave in New York City. Empirical confirmation of double-parked delivery impact on signalized controlled delay remains elusive due to an inability to isolate the effects of the deliveries from other traffic perturbations in the video sample. Instead, microscopic simulation using Aimsun is used for comparison to the theoretical models and the results lend credibility to the Detailed model. The simulation results show a similar trend of delay impact from double-parked deliveries located at a range distances from the intersection and more closely resembled the Detailed model. The All-or-Nothing model would provide only a coarse representation of the capacity and delay effects. The more detailed approach that accounts for the dynamics of queuing in front of the delivery vehicle provides closed form analytical formulas for capacity and signalized control delay that can account for varying locations of deliveries as well as analysis periods with some blocked cycles and others unblocked. Two policy implications are proposed: 1) that double-parked deliveries located mid-block likely result in less signalized control delay impact, and 2) freight receivers that attract double-parked deliveries near an intersection stop line should be prioritized in urban freight delivery mitigation policies such as off-hour delivery.

description: The study examines the current feed use in the rapidly-growing Indian poultry sector and evaluates the potential economic impact of using biofortified maize with higher levels of amino acids as feed. Data collected from 185 poultry firms of South India form the empirical base. A significant share of broiler firms were found using amino acids in quantities above the recommended levels with negligible production and negative profitability effects, demonstrating a clear dearth of managerial skill to obtain and utilize information on poultry nutrition. A linear programming model for estimating the least-cost feed formulation showed that the potential economic impact of biofortified maize is limited by the availability of low-cost protein from the alternative sources, and that the potential cost savings from the technology would be marginal. Similar findings were obtained from additional estimation done by relaxing the assumption that the firms have perfect information on feed formulation. Also, lack of awareness of the small-scale firm management regarding poultry nutrition could pose additional challenges in the development of innovative maize-poultry value chains for diffusion of this innovation.

description: Previous work on high-density QCD suggests that the ground state configuration in the presence of a non-zero neutrino chemical potential consists of CFL matter plus a homogenous condensate of neutral and positive kaons. We consider here the stability of this homogenous configuration toward the production of a charge-separated mixed phase, and find that the system is indeed stable against the production of such a heterogenous configuration. We identify the critical value of the fine structure constant which would allow for phase separation. We also derive dispersion relations for the low-lying excitations above the kaon-condensed ground state and discuss their possible phenomenological implications.

description: After periods of progress, prevalence of undernutrition has been increasing in many low- and middle-income countries (LMICs) since 2015. At the same time, with an increase of obesity rates a second burden has been imposed on people living in LMICs. Many common drivers of both forms of malnutrition led to a double-duty call for action to fight undernutrition and obesity simultaneously and with combined resources. The joint effort is of utmost importance, more than ever in light of increasing food insecurity and poverty caused by the COVID pandemic. However, studies of the growing body of obesity interventions have not thoroughly incorporated an impact evaluation of undernutrition, and a comprehensive literature review is missing. To systematically review obesity interventions in LMICs, main relevant databases have been used. We found that deliberate attention to undernutrition is yet rare which calls for a continuous emphasis of the double-duty focus shift.

description: We develop perturbative expansions to obtain solutions for the initial-value problems of two important reaction-diffusion systems, viz., the Fisher equation and the time-dependent Ginzburg-Landau (TDGL) equation. The starting point of our expansion is the corresponding singular-perturbation solution. This approach transforms the solution of nonlinear reaction-diffusion equations into the solution of a hierarchy of linear equations. Our numerical results demonstrate that this hierarchy rapidly converges to the exact solution.

A NUMERICAL FLUTTER PREDICTOR FOR 3D AIRFOILS USING THE ONERA DYNAMIC STALL MODEL
Creators: name: Boersma, Pieter
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: To be able to harness more power from the wind, wind turbine blades are getting longer. As they get longer, they get more flexible. This creates issues that have until recently not been of concern. Long flexible wind turbine blades can lose their stability to flow induced instabilities such as coupled-mode flutter. This type of flutter occurs when increasing wind speed causes a coupling of a bending and a torsional mode, which create limit cycle oscillations that can lead to blade failure. To be able to make the design of larger blades possible, it is important to be able to predict the critical flutter and post critical flutter behaviors of wind turbine blades.
Most numerical research concerning coupled-mode wind turbine is focused on predicting the critical flutter point, and less focused on the post critical behavior. This is because of the mathematical complexities associated with the coupled, nonlinear wind turbine blade systems. Here, a numerical model is presented that predicts the critical flutter velocity and post critical flutter behavior for 3D airfoils with third order structural nonlinearities. The numerical model can account for the attached flow and separated flow region by using the ONERA dynamic stall model. By retaining higher-order structural nonlinearities, lateral and torsional displacements can be predicted, which makes it possible to use this model in the future to control wind turbine blade flutter. Furthermore, by using a dynamic stall model to simulate the flow, the solver is able to predict accurate limit cycle oscillations when the effective angle of attack is larger than the stall angle.
The coupled, nonlinear equations of motion are two coupled nonlinear PDEs and are determined using Hamilton’s principle. In order to solve the equations of motion, they are discretized using the Galerkin technique into a set of ODEs. The motion of the airfoil is used as an input to ONERA. The airfoil is sectioned with the lateral position and angle of attack known as well as the velocity and acceleration of the section at an instance of time. This information is used by ONERA to calculate lift and moment coefficients for each section which are then used to calculate the total lift and moment forces of the airfoil. Then, a Fortran code solves the system by using Houbolt’s finite difference method.
A theoretical NACA 0012 airfoil has been designed to define the parameters used by the equations of motion. Third bending and first torsional coupling occurs after the critical flutter point and dynamic lift and moment coefficients were observed. Dynamic stall was also observed at wind velocities farther away from the bifurcation point. Bifurcation diagrams, time histories, and phase planes have been created that represent the flutter behavior.

Our result reproduces the Ostriker-Vishniac effect to second order in perturbation theory but contains nonlinear corrections to the electron velocities and densities that were neglected previously. We use the recently developed halo model for nonlinear gravitational clustering to compute the nonlinear kinetic SZ power spectrum, which dominates the primary anisotropy on small angular scales.

description: In the paper, based on recent studies on $T\bar{T}$ deformation of 2D field theory with supersymmetry, we investigate the deformed correlation functions in $\mathcal{N}=(1,1)$ and $\mathcal{N}=(2,2)$ 2D superconformal field theories. Up to the leading order in perturbation theory, we compute the correlation functions under $T\bar{T}$ deformation. The correlation functions in these undeformed theories are almost known, and together with the help of superconformal Ward identity in $\mathcal{N}=(1,1)$ and $\mathcal{N}=(2,2)$ theories respectively we can obtain the correlation functions with operator $T\bar{T}$ inserted. Finally, by employing dimensional regularization, we can work out the integrals in the first order perturbation. The study in this paper extends previous works on the correlation functions of $T\bar{T}$ deformed bosonic CFT to the supersymmetric case.

Investigating the Role of RNA-Binding Protein 5 in the Life Cycle Differentiation of Trypanosoma Brucei
Creators: name: Anaguano Pillajo, David
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Trypanosomatid parasites such as Trypanosoma brucei have unusual mechanisms of gene expression including polycistronic transcription, mitochondrial RNA editing and trans-splicing. Additionally, these protists rely mainly on post-transcriptional regulation where RNA-binding proteins (RBP) have shown to play a major role. RBP6 and RBP10 are two examples of RBPs that play crucial roles in procyclic and bloodstream form parasites differentiation respectively, by post-transcriptional regulation. Over-expression of RBP6 is enough to promote differentiation into metacyclic trypomastigotes that are infective to mice. However, continuous expression is required, and this pattern does not reflect the natural expression in the tsetse fly or the influence of other RNA-binding proteins. RBP5 is a RBP with a single RNA-recognition motif similar to RBP6 and RBP10, whose expression is upregulated during the life stages within the salivary glands of tsetse flies. We hypothesize the RBP5 facilitates metacyclogenesis in the tsetse fly. To evaluate possible contributions to T. brucei differentiation, we will over-express RBP5 in procyclic cells alone and in combination with RBP6. Initial screening of cells over-expressing PTP-tagged RBP5 resulted in parasites with a moderate growing defect, and the scoring of nuclei and kinetoplasts in fixed cells showed a progressive accumulation of cells with 2 nuclei and 2 kinetoplasts (2N2K) and appearance of multinucleated cells. On the other hand, over-expression of non-tagged RBP5 generated a more severe growing defect, starting immediately after the first day of induction. The scoring of nuclei and kinetoplasts resulted in a drastic increase of 2N2K cells and a greater appearance of multinucleated cells, which suggests an irregular cell cycle progression. When developing the dual over-expression system, our cells over-expressing RBP6 were not able to differentiate into any stage, and when over-expressing RBP5 and RBP6 coordinately, no differentiation process was observed either. Together these data suggest that RBP5 might be a regulator of genes involved in the initiation of cytokinesis in T. brucei parasites, however a role in metacyclogenesis cannot be discarded since we were not able to obtain metacyclic parasites. This study helped us to get a better understanding of the post-transcriptional regulatory mechanisms that repress and regulate T. brucei cell cycle progression.

SkinnySensor: Enabling Battery-Less Wearable Sensors Via Intrabody Power Transfer
Creators: name: Kiran, Neev
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Tremendousadvancement inultra-low powerelectronics and radiocommunica tionshas signiﬁcantly contributed towards the fabrication of miniaturized biomedical sensors capable of capturing physiological data and transmitting them wirelessly. However, most of the wearable sensors require a battery for their operation. The battery serves as one of the critical bottlenecks to the development of novel wearable applications, as the limitations oﬀered by batteries are aﬀecting the development of new form-factors and longevity of wearable devices. In this work, we introduce a novel concept, namely Intra-Body Power Transfer (IBPT), to alleviate the limitations and problems associated with batteries, and enable wireless, batteryless wearable devices. The innovation of IBPT is to utilize the human body as the medium to transfer power to passive wearable devices, as opposed to employingon-boardbatteries for each individual device. The proposed platform eliminates the on-board rigid battery for ultra-low power and ultra-miniaturized sensors such that their form-factor can be ﬂexible, ergonomically designed to be placed on small body parts. The platform also eliminates the need for battery maintenance (e.g., recharging or replacement) for multiple wearable devices other than the central power source. The performance of the developed system is tested and evaluated in comparison to traditional Radio Frequency based solutions that can be harmful to human interaction. The system developed is capable of harvesting on average 217µW at 0.43V and provides an average sleep/high impedance mode voltage of 4.5V.

description: Physical event detection has long been the domain of static event processors operating on numeric sensor data. This works well for large scale strong-signal events such as hurricanes, and important classes of events such as earthquakes. However, for a variety of domains there is insufficient sensor coverage, e.g., landslides, wildfires, and flooding. Social networks have provided massive volume of data from billions of users, but data from these generic social sensors contain much more noise than physical sensors. One of the most difficult challenges presented by social sensors is \textit{concept drift}, where the terms associated with a phenomenon evolve and change over time, rendering static machine learning (ML) classifiers less effective. To address this problem, we develop the ASSED (Adaptive Social Sensor Event Detection) framework with an ML-based event processing engine and show how it can perform simple and complex physical event detection on strong- \textit{and} weak-signal with low-latency, high scalability, and accurate coverage. Specifically, ASSED is a framework to support continuous filter generation and updates with machine learning using streaming data from high-confidence sources (physical and annotated sensors) and social networks. We build ASSED to support procedures for integrating high-confidence sources into social sensor event detection to generate high-quality filters and to perform dynamic filter selection by tracking its own performance. We demonstrate ASSED capabilities through a landslide detection application that detects almost 350\% more landslides compared to static approaches. More importantly, ASSED automates the handling of concept drift: four years after initial data collection and classifier training, ASSED achieves event detection accuracy of 0.988 (without expert manual intervention), compared to 0.762 for static approaches.

No evidence for excited neutrino production is found. Mass dependent exclusion limits are determined for the ratio of the coupling to the compositeness scale, f/Lambda, independently of the relative couplings to the SU(2) and U(1) gauge bosons. These limits extend the excluded region to higher masses than has been possible in previous searches at other colliders.

description: This study examines the crucial role of middle management in mitigating intergenerational conflicts within the Moroccan banking sector. In a context of digital transformation and cohabitation of several generations with different values and expectations, middle managers play a key role as interface and mediators. Using structural equation modeling on a sample of 500 employees, the study analyzes the relationships between middle management practices, organizational climate, employee engagement, and the intensity of intergenerational conflicts. The results show that adaptive communication practices, transformational leadership, and diversity management of middle management have a significant impact on reducing conflicts, mediated by improving the organizational climate and increasing employee engagement. The study also highlights generational differences in the perception and impact of these managerial practices. These findings emphasize the crucial importance of middle management in managing generational diversity and offer concrete avenues for improving intergenerational cohesion in the Moroccan banking sector.

description: In the context of the minimal supersymmetric seesaw model, we study the implications of the current neutrino data for thermal leptogenesis, $ββ_{0ν}$ decay, and leptonic flavour- and CP-violating low-energy observables. We express the heavy singlet-neutrino Dirac Yukawa couplings $(Y_ν)_{ij}$ and Majorana masses $M_{N_i}$ in terms of the light-neutrino observables and an auxiliary hermitian matrix $H$, which enables us to scan systematically over the allowed parameter space. If the lightest heavy neutrino $N_1$ decays induce the baryon asymmetry, there are correlations between the $M_{N_1}$, the lightest active neutrino mass and the primordial lepton asymmetry $ε_1$ on the one hand, and the $ββ_{0ν}$ decay parameter $m_{ee}$ on the other hand. {\it However, leptogenesis is insensitive to the neutrino oscillation phase}. We find lower bounds $M_{N_1}\gsim 10^{10}$ GeV for the normal light-neutrino mass hierarchy, and $M_{N_1}\gsim 10^{11}$ GeV for the inverted mass hierarchy, respectively, indicating a potentially serious conflict with the gravitino problem. Depending on $M_{N_1}$, we find upper (upper and lower bounds) on the lightest active neutrino mass for the normal (inverted) mass hierarchy, and a lower bound on $m_{ee}$ even for the normal mass ordering. The low-energy lepton-flavour- and CP-violating observables induced by renormalization are almost independent of leptogenesis. The electron electric dipole moment may be close to the present bound, reaching $d_e\sim 10^{-(27-28)}$ e cm in our numerical examples, while $d_μ$ may reach $d_μ\sim 10^{-25}$ e cm.

description: The design optimisation of aerostructures is largely based on Multidisciplinary Design Optimisation (MDO), which is a tool used by the aircraft industry to size primary structures: wings, large portions of the fuselage or even an entire aircraft. This work extends an existing MDO procedure for aircraft design to consider the sizing of separately modelled, detailed features. In order to minimise the additional computational cost, this involves the implementation of a global-local analysis and an ad-hoc semi-analytical coupled sensitivity analysis. The proposed global-local MDO leads to more reliable design solutions without incurring significant computational costs.

The ``intelligent'' agents play the basic minority game and depending on their performances, generate new strategies using the one-point genetic crossover mechanism. The performances change dramatically and the game moves rapidly to an efficient state (fluctuations in the number of agents performing a particular action, characterized by $σ^2$, reaches a low value). There is no ``phase transition'' when we vary $σ^2/N$ with $2^M/N$, where $M$ is the ``memory''of an agent.

description: The study of the extragalactic background light (EBL) in the optical and near infrared has received a lot of attention in the last decade, especially near a wavelength of $λ\approx 3.4\operatorname{μm}$, with remaining tension among different techniques for estimating the background. In this paper we present a measurement of the contribution of galaxies to the EBL at $3.4\operatorname{μm}$ that is based on the measurement of the luminosity function (LF) in Lake et al. (2018) and the mean spectral energy distribution of galaxies in Lake & Wright (2016). The mean and standard deviation of our most reliable Bayesian posterior chain gives a $3.4\operatorname{μm}$ background of $I_ν= 9.0\pm0.5 \operatorname{kJy} \operatorname{sr}^{-1}$ ($νI_ν= 8.0\pm0.4 \operatorname{nW} \operatorname{m}^{-2} \operatorname{sr}^{-1} e\operatorname{-fold}^{-1}$), with systematic uncertainties unlikely to be greater than $2\operatorname{kJy} \operatorname{sr}^{-1}$. This result is higher than most previous efforts to measure the contribution of galaxies to the $3.4\operatorname{μm}$ EBL, but is consistent with the upper limits placed by blazars and the most recent direct measurements of the total $3.4\operatorname{μm}$ EBL.

A principal finding of the research is that global warming is perceived as almost inevitable and will lead to major changes in global food production, processing, and trade. However, the dynamic nature of the food chain offers many possibilities to mitigate the negative supply system impacts of global warming through efficiencies gained by increasing firm concentration in the agri-food sector through the application of biotechnology, or adaptations in local food production.

This study aims to identify the key success factors of innovation project performance of vegetable breeding companies (VBCs) in China. Based on empirical data that was collected from 53 innovation projects in 38 VBCs, it was found that integrative capabilities play an important role in the novelty and newness of the innovation to enhance product potential (superiority) and also in improving functional capabilities and in gaining market potential. Furthermore, market competition is a positive factor for inspiring innovation in the breeding industry.

Further extensions are to systems containing many fermions, with the master equations modified to take Fermi-Dirac statistics into account, and to potentials with a time-dependent bias that induce resonant avoided crossing transitions. The limit $Q \to \infty$, where the interaction rate with the bath is much greater than all free oscillation rates for the system, is interrogated. Two behaviors are possible: freezing (quantum Zeno effect) or synchronization (motional narrowing). We clarify the conditions that give rise to each possibility, making an explicit connection with quantum measurement theory. We compare the evolution of quantal coherence for the two cases as a function of $Q$, noting that full coherence is restored as $Q \to \infty$. Using an extended master equation, the effect of system-bath interactions on entanglement in bipartite system states is computed. In particular, we show that the sychronization case sees bipartite system entanglement fully preserved in the large $Q$ limit.

Searching for the Fulcrum: Can Accountable Care Organizations Lower Spending by Balancing Specialists-to-Primary Care Providers?
Creators: name: Shetty, Vishal

description: Background:
While value-based payment models emphasizing care coordination have been widely implemented to improve quality and lower expenditures, supporting empirical evidence is sparse. Our objective was to quantify the impact of specialist-to-primary care physician involvement within accountable care organization (ACO) and its association with lower spending.
Methods:
We conducted a retrospective cohort study of Medicare Shared Savings Program ACOs from 2012-2016 using publicly available data provided by the Centers for Medicare and Medicaid Services at the ACO level. We examined the association between the proportion of primary care services delivered by specialists versus other types of care providers and ACO spending using a generalized estimating equation model.
Results:
The analytic dataset included 1381 MSSP-years. When compared to ACOs at the lowest (60) levels of providing primary care services through specialists, ACOs who had 35% to 40% of primary care services delivered by specialists spent $1,124 (95% CI, $358 to $1,891) and $969 (95% CI, $250 to $1,688) less per capita, respectively. When stratified at varying levels of specialists providing primary care services, having four years of experience in the Medicare Shared Savings Program was consistently associated with lower spending when compared to having one to three years of experience.
Conclusions and Relevance:
The optimal portion of specialists providing primary care services - to reduce spending - was found to be 35% to 40%. These findings suggest that integrating specialists in to the activities and objectives of MSSP ACOs could lead to lower spending and better performance.

description: We report on the far-infrared magnetospectroscopy of HgTe quantum wells with inverted band ordering at different electron concentrations. We particularly focus on optical transitions from zero-mode Landau levels, which split from the edges of electron-like and hole-like bands. We observe a pronounced dependence of the transition energies on the electron concentration varied by persistent photoconductivity effect. This is striking evidence that in addition to the already well-documented crystalline and interface asymmetries, electron-electron interactions also have a significant impact on the usual behavior of the optical transitions from zero mode Landau levels.

description: For a particle channeled in the bent crystal planes (axes), the phenomenon of "bending dechanneling", which is a particle transition to a random state due to centrifugal force, is well known. We consider an analytical theory of the reverse phenomenon, i.e., feeding from a random state to a channeled state due to centrifugal force in a crystal with variable curvature.

description: There is currently much debate surrounding the housing systems for dairy cattle. Large farms, which represent a growing share of the dairy farms, prefer indoor housing systems whereas smaller farms concentrate on low-input systems by giving extended pasture access to milk cows. A consumer survey from 2013 with 1,009 German consumers dealt with consumers’ attitudes towards outdoor and indoor systems as well as quality aspects of food. A factor and a cluster analysis are used to reduce the complexity and identify different consumer clusters. The results give recommendations for farmers, constructors of animal sheds, agricultural technology and the processing dairy industry concerning strategic decisions.

description: A Lorenz-like model was set up recently, to study the hydrodynamic instabilities in a driven active matter system. This Lorenz model differs from the standard one in that all three equations contain non-linear terms. The additional non-linear term comes from the active matter contribution to the stress tensor. In this work, we investigate the non-linear properties of this Lorenz model both analytically and numerically. The significant feature of the model is the passage to chaos through a complete set of period-doubling bifurcations above the Hopf point for inverse Schmidt numbers above a critical value. Interestingly enough, at these Schmidt numbers a strange attractor and stable fixed points coexist beyond the homoclinic point. At the Hopf point, the strange attractor disappears leaving a high-period periodic orbit. This periodic state becomes the expected limit cycle through a set of bifurcations and then undergoes a sequence of period-doubling bifurcations leading to the formation of a strange attractor. This is the first situation where a Lorenz-like model has shown a set of consecutive period-doubling bifurcations in a physically relevant transition to turbulence.

description: We show that in realistic constituent quark models based on a two-body confinement interaction color states appear in the middle of the experimentally known spectrum. To avoid this situation we implement a three-body confinement interaction, introduced on an algebraic basis, into a semirelativistic version of the Goldstone-boson-exchange constituent quark model and by solving the Faddeev equations we show that this interaction can increase the gap between singlet and colour states, such as the latter can be ignored and the known baryons can be described as $q^3$ systems. We analyze the effect of a $Δ$- and a Y-shape three-body interaction.

description: Potential structural changes among eight North America natural gas spot markets are investigated. Evidence from parameter instability tests of the long-run pricing relationship infers possible structural changes occurred around 2000 and again around 2009. Possible contributing factors to the structural changes around 2000 are U.S. Federal Energy Regulatory Commission Order, California’s electricity crisis, 9/11 terrorist attacks, changes in imports, and increased price volatility. The likely major contributing factor to the break occurring around 2009 is the shale gas revolution. Extreme weather events appear to cause transient instability, which should not be considered structural shifts. Results shade some light on why previous studies have conflicting results; the failure to consider structural changes. Further studies regarding potential structural changes and their effects on the natural gas market are necessary.

ClpXP-regulated Proteins Suppress Requirement for RecA in Dam Mutants of Escherichia coli K-12
Creators: name: Savakis, Amie
Publisher: name: University of Massachusetts Amherst
Year: 2018

description: Double strand breaks (DSB) are a common source of DNA damage in both prokaryotes and eukaryotes. If they are not repaired or are repaired incorrectly, they can lead to cell death (bacteria) or cancer (humans). In Escherichia coli, repair of DSB are typically accomplished via homologous recombination and mediated by RecA. This repair pathway, among others, is associated with activation of the SOS response. DNA adenine methyltransferase (dam) mutants have an increased number of DSB and, therefore, are notorious for being RecA-dependent for viability. Here, we show that the synthetic lethality of Δdam/ΔrecA is suppressed when clpP is removed, suggesting that there is a protein, normally degraded by ClpXP, which is preventing DSB from occurring.

description: In this paper the usual $Z_2$ graded Lie algebra is generalized to a new form, which may be called $Z_{2,2}$ graded Lie algebra. It is shown that there exists close connections between the $Z_{2,2}$ graded Lie algebra and parastatistics, so the $Z_{2,2}$ can be used to study and analyse various symmetries and supersymmetries of the paraparticle systems.
