Authors:   University of California, San Diego, Rabinovich Mihail , Varona Pablo ,   Universidad Autonoma de Madrid, Afraimovich Valentin ,   Universidad Autónoma de San Luis Potosí
Published: February 2024

Information processing in neural networks by computation with attractors (steady states, limit cycles, strange attractors) has been extensively discussed in application to many neural systems: central pattern generators, sensory systems (e.g. visual, olfactory), hippocampus, etc. Computation with attractors in a traditional way faces а fundamental contradiction between robustness and sensitivity. In this paper we discuss а new direction in information neurodynamics based on experiments performed in the locust olfactory system, the orientation sensory system of the marine mollusk Clione апа the hippocampal place cell networks. This new concept uses the transformation of the incoming spatial or identity information into spatio-temporal output based on the intrinsic switching dynamics of neural networks with nonsymmetric inhibitory connections. This is called the Winner-Less Competition Principle (WLC). The key feature of а network that computes with separatrices is the robustness against noise and the simultancous sensitivity of the sequence of switching to the incoming information. We present rigorous results about the stability of the sequential switching in the framework оf the Lottka-Volterra model. Because оf their fast reaction, the discussed neural networks are able 10 change their intrinsic dynamics to respond to new incoming information and solve many different functional tasks. Computation with separatrices can also be an optimal principle for the design of new paradigms of artificial neural networks.

Authors:   Saratov State University, Klimova Oksana , Semenova Maria ,   Saratov State University, Anishchenko Tatyana ,   Saratov State University, Igosheva Natalia ,   Cambridge Clinical Trials Unit
Published: February 2024

In this research we studied the cardiovascular sensitivity to parasympathetic blockade in normal and castrated male and female rats under usual and stress conditions using the traditional physiological measures and a new measure of complexity of blood pressure dynamics - normalized entropy Е/Н. The results showed that changes in E/H were more pronounced and prolonged in comparison with heart rate and blood pressure. Also, unlike the latter, Е/Н increased in one part оf rats аn decreased in another part оf ones. These quantitative аnd qualitative particularities in Е/Н changes give evidence that using a new measure of complexity degree of blood pressure signal one can receive an additional information about the changes in cardiovascular system evoked by different perturbations.

Authors:   Saratov State University, Anishchenko Tatyana , Glushkovskaya-Semyachkina Oksana ,   Saratov State University
Published: February 2024

In experiments оn rats оf both sexes wе investigated the sensitivity оf cardiovascular system to sympathetic and parasympathetic blockade using physiological parameters - heart rate, arterial pressure and a new criteria of complexity of blood pressure dynamics - normalized entropy. The results showed that in females compared with males cardiovascular system is more sensitive to pharmacological agents blocking the sympathetic and parasympathetic influences. These facts suggest that autonomic nerves regulation of cardiovascular system is more pronounced in females than in males. The normalized entropy was demonstrated to be more sensitive criteria of changes in cardiovascular system induced by pharmacological agents. Our data suggested that new measure of the complexity degree of blood pressure dynamics may be useful for evaluation оf cardiovascular response to different external and internal perturbations.

Authors:   Saratov State University, Belyaev Mikhail , Lazerson Aleksandr ,   Saratov State University
Published: February 2024

Complex dynamics of a quantum periodically driven square well is considered. It is shown that analysis оf its ensemble average energy time series provides ап identification of its dynamics to be either regular or chaotic. It has been found that enhancement of the driving force causes the energy spectrum to look like a spectrum of some random process, which may be identified as the signature of chaos in а quantum system.

Published: February 2024

Complex reactive dynamics оn low-dimensional lattices is studied using mean-field model and Monte-Carlo simulation. We consider four-species cyclic chemical reactions оn one- аnd two-dimensional catalytic supports. The resulted mean-field model is conservative. Depending оn parameters it shows quasi-periodic оr chaotic oscillations. One-dimensional lattice does not demonstrate oscillating behavior due to the geometric restrictions. Lattice Monte-Carlo simulations оn two-dimensional lattices show locally emergence оf chaotic oscillations which are resulted from complex motions and interactions of clusters оf homogeneous species. The properties оf the oscillations depends оп the size оf the lattice.
Characterization оf thе parameter-mismatching and noise effect оn weak synchronization

Published: February 2024

We investigate the effect of noise and parameter mismatching оn the loss оf chaos synchronization in coupled one-dimensional maps. Due to existence of positive local transverse Lyapunov exponents, the weakly stable synchronous chaotic attractor demonstrates sensitivity with respect to variation of the mismatching parameter оr noise intensity. In order to characterize such parameter and noise sensitivity quantitatively, we introduce new quantifiers, called the parameter sensitivity exponent and noise sensitivity exponent. The values of these exponents are determined by local stability multipliers of the chaotic trajectories, and by the properties of the noise signal (for the noise sensitivity exponent). For the case оf bounded uniform noise, the values of the parameter sensitivity exponent and noise sensitivity exponent coincide. In terms of these exponents, we characterize the effect of parameter-mismatching and noise оn the intermittent bursting and basin riddling occurring in the regime of weak synchronization.
Investigation of universal properties of external synchronization threshold in chaotic systems
Authors:   Saratov State University, Loginova Maria , Anishchenko Vadim ,   Saratov State University
Published: February 2024

In this paper the dependence of amplitude threshold of synchronization on Kolmogorov entropy is considered. The influence of nonhyperbolicity оп this regularity is investigated. Synchronization of chaos takes place when chaotic regime changes to a regular one with external force parameters changing. In this case synchronization appears when the amplitude оf external force is rather big, that means the amplitude threshold takes place. The hypothesis about universality of the exponential dependence between amplitude threshold and Kolmogorov entropy is checking by investigation of Lorenz system in quasihyperbolic regime. The influence оf nonhyperbolicity оп the regularity got for hyperbolic systems is investigated. For this purpose we consider nonhyperbolic attractor in Lorenz system and funnel and spiral nonhyperbolic attractors in Roessler system.

Published: February 2024

We study the noisy FitzHugh-Nagumo model in the presence оf аn external sinusoidal driving force. We derive a Fokker-Planck equation for both the single element and for the globally coupled system. We introduce аn efficient way to numerically solve this Fokker-Planck equation and show that the external driving force leads to a classical resonance when its frequency matches the underlying systems frequency. This resonance is also investigated analytically by exploiting the different timescales in the problem. Agreement between the analytical results and numerical results is excellent and reveals the existence оf а stochastic bifurcation.

A recently developed method for the detection of phase synchronization between several oscillatory processes from one-dimensional signals has been extended to allow estimation of synchronization indices. It has been applied to blood pressure signals from freely moving rats. Each rat underwent four stages: 1) healthy; 2) healthy but challenged by beta-blockers; 3) with stress-induced myocardial injuries; 4) with the stress-induced injuries challenged by beta-blockers. It is shown that cardiorespiratory synchronization plays аn essential role at each оf these stages.

The individual functional unit оf the kidney (the nephron) displays oscillations in its regulation оf the incoming blood flow аt two different time scales: fast oscillations associated with а myogenic dynamics of the afferent arteriole, and slower oscillations arising from а delay in the tubuloglomerular feedback. The paper investigates the intra- and inter-nephron interactions of these two modes. Besides full synchronization, both wavelet analyses of experimental data and numerical simulations of a detailed physiological model reveal the occurrence of а partial entrainment in which neighboring nephrons attain а state оf synchronization with respect to their slow dynamics, but the fast dynamics remain desynchronized.

Published: February 2024

Dynamics оf ions in the geotail magnetic field reversal plasmas is modelled with а hybrid code. Poincare maps are calculated for stationary and for adiabatically changing field configurations starting from an anisotropic pressure self-consistent equilibrium. It is shown that the essential dynamics as found previously for single particle in prescribed fields persists in the hybrid code simulations of self-consistent fields. The possible interplay of dynamical processes in the Earth’s magnetosphere and in the solar wind is discussed.

Authors:   Institute of Mathematics of the National Academy of Sciences of Ukraine, Yanchuk Serhiy , Kapitaniak Tomasz ,   Lodz University of Technology
Published: February 2024

Riddling bifurcation leads to the loss of chaos synchronization in coupled identical systems. We discuss here the manifestation of the riddling bifurcation for the case of a small parameter mismaich between coupled systems. We show that for slightly nonidentical coupled systems, the transverse growth of the synchronous attractor is mediated by transverse bifurcations of unstable periodic orbits embedded into the attractor.
Evolution of running waves to spatio-temporal chaos: interaction of temporal and spatial dynamics in a ring of period-doubling self-oscillators
Authors:   Saratov State University, Shabunin Aleksej , Astakhov Vladimir ,   Yuri Gagarin State Technical University of Saratov, Akopov Artem ,   Saratov State University
Published: February 2024

In the work we consider transition from regular running waves to developed spatio-temporal chaos in а chain оf period-doubling oscillators. We investigate typical bifurcations which take place оn thе base of the chosen running wave regime from the period-one cycle to developed temporal chaos. We found that oscillations remain spatially periodic until transition to temporal chaos. The exact spatial periodicity is changed by the periodicity in the average in the chaotic region. Destroying of the averaged spatio-periodic structure is connected with losing оf coherence оn main frequencies in the temporal spectra оf neighbor oscillators in the chain.

Published: February 2024

This paper provides а short review оf recent results оn synchronization in small-world dynamical networks of coupled oscillators. We also propose a new model of small-world networks of cells with a time-varying coupling and study its synchronization properties. It is shown that such а time-varying structure of the network can ensure more reliable synchronization than the conventional small-worlds. The term «small world» refers to a network of locally connected nodes having a few additional long-range shortcuts chosen at random. The addition оf thе shortcuts sharply reduces the average distance between the nodes and therefore provides the so-called small-world effect. Discovered first in social networks, the small-world effect appeared to be а characteristic оf many real-world structure both human-generated ог of biological origin. For social networks, this property implies that almost any pair of people in the world can be connected to one another by a short chain of intermediate acquaintances, of typical length about six. However, the structure оf social networks is not homogeneous, there are always key persons аn provide distant out-local world connections between people. This paper is written in honor оf the 60th birthday оf our friend and colleague, Wadim S. Anishchenko, who is one of such key persons in the Nonlinear Dynamics community.

The dynamical features of spike train generation in the presence of noise are investigated for three different models of neural rhythm generators: а single neuron model that simulates impulse pattern modulation for temperature encoding in mammalian cold receptors, а minimal neural network that describes transitions between beta and gamma rthythms in the brain and аn electronic switching device that represents а simple breathing rhythm generator for а snail. We show that noise can explain а number оf peculiarities in the observed spike trains, cause coherent switchings between different states, and induce new rhythms in small neural ensembles.

Published: February 2024

In the IT sector, cloud computing is a rapidly expanding technology. Users are being offered more and more flexible and appropriate services by cloud service providers (CSP). Cloud computing users are increasing at a steady pace. Users and CSP are looking for appropriate security measures as cloud computing becomes a need in modern life. A large number of researchers are studying cloud computing security issues. This work introduces an appropriate cryptography and secure user authentication system, which includes auto encryption and a mechanism for updating keys on a cloud site that is not initially accessible to users. After a predetermined amount of time, this operation will recur frequently on the cloud site. This protocol can be carried out manually by CSP at any time, or it can run automatically after a predetermined amount of time. This will guarantee additional data security. Additionally, this procedure adds a level to the user's credentials. Even with legitimate credentials, these feathers will ensure that hackers cannot obtain original files or data. The suggested protocol is emulated by CloudSim, and we saw that there is an additional step requiring user credentials, requiring some time to access files or data for the first time. Although this small amount of time is insignificant and can be disregarded, it significantly improves security.
Le lait de chamelle au risque de l’économie politique : de l’économie du don à l’économie marchande
Authors: Faye Bernard , Corniaux Christian
Published: February 2024

Le lait de chamelle a longtemps été exclu du marché compte tenu de sa seule disponibilité dans les régions parmi les plus reculées de la planète. Ce contexte est sans doute en partie à l’origine de la conviction qu’avaient les éleveurs chameliers selon laquelle, la vente de lait de chamelle relevait d’un « tabou » à qui on donnait éventuellement une dimension religieuse. Pourtant, associée uniquement à l’économie du don, cette posture a radicalement évolué en quelques décennies vers une économie marchande pour une part capitaliste. Le présent article tente de mobiliser ces concepts d’économie du don et d’économie marchande pour comprendre les mutations en cours et s’appuie sur l’exemple du Sultanat d’Oman pour illustrer ce que peut signifier la marchandisation du lait de chamelle. Le cas du Sultanat d’Oman est emblématique au sens où l’évolution y est récente et extrêmement rapide dans un contexte environnemental et socio-politique tout-à-fait particulier. Si les changements évoqués s’appuient sur l’exemple omanais, ils apparaissent largement universels et expliquent la forte croissance attendue de ce commerce du lait à l’échelle mondiale et pas seulement dans les pays traditionnellement producteurs.

This article describes two clinical observations of the use of mepolizumab in patients with severe uncontrolled asthma with a mixed granulocytic pattern of inflammation in the bronchi and comorbid pathology. The mixed granulocytic form of severe asthma is characterized by a combination of T2 endotype and non-T2 endotype. The most common mixed granulocytic pattern of severe asthma occurs in comorbid pathology, in particular, when it is combined with chronic obstructive pulmonary disease (COPD) or bronchiectasis.

In the presented observations, both patients had an experience of smoking, a late manifestation of bronchial asthma with the development of centrilobular emphysema and an irreversible decrease in the FEV/FVC ratio as part of the development of COPD. A feature of one of the cases was the presence of cylindrical bronchiectasis in both lungs. The choice of mepolizumab as an additional maintenance agent at GINA stage 5 in both cases was justified by the uncontrolled course of asthma despite the use of a high dose of glucocorticosteroids in combination with other basic drugs and the need for the use of systemic corticosteroids > 50 % of the time per year, a history of recurrent exacerbations in previous 12 months, the presence of persistent blood eosinophilia (>150 cells/μl), as well as a combination of asthma with polypous rhinosinusitis in one of the patients.

Overall, the use of mepolizumab 100 mg subcutaneously every four weeks in addition to regular maximum optimized maintenance therapy was characterized by rapid, signifi cant and sustained effi cacy, which was expressed in early achievement of asthma control within the fi rst 16 weeks of therapy.

A real-world study with clinical and economic assessment of the use of succinate-containing drugs in patients with alcoholic liver disease was conducted. The study was based on data from Buyanov City Clinical Hospital in Moscow and Mirotvortsev Clinical Hospital in Saratov. The period of the study was from 2019 to 2022. The main analyzed factor was the duration of hospitalization and 60 patients with alcoholic liver disease and blood transaminases exceeding two norms and blood ammonia more than one and a half norms were included in the study. Of 60 patients 36 used succinate-containing drugs as part of complex therapy (main group) and 24 did not receive them (control group).

The dynamics of indicators of clinical and instrumental status of patients did not differ in both groups (V=0.35; F=0.87; p=0.614). The modelling by Markov chains was performed. The use of succinate-containing drugs demonstrated 8.3 % reducing of costs per case of alcoholic liver disease cure due to the average reduction of hospitalization by 2.42 days.

Objectives. Evaluation of the relationship of clinical, laboratory and morphological factors with remodeling of small-diameter renal arteries in patients with glomerulonephritis (GN) and arterial hypertension (AH). Materials and methods. The study included 105 patients (average age 37.1±1.2 years) with primary GN and hypertension who had indications for morphological investigation of kidney tissue. All patients underwent a standard examination for kidney disease, a morphological study of kidney tissue with a description of the changes that occur in the presence of glomerulonephritis, corresponding to the individual severity of the pathological process. The presence of signs of a tubulointerstitial component of damage (or tubulointerstitial component — TIC) in the form of tubulointerstitial infl ammation (TIV), fi brosis (TIF) was assessed. Vasometry of the interlobular artery (IA) was performed. The value of the intima-media complex (IMC) was considered to be a sign of IA remodeling. A sign of MA remodeling was considered to be an intima-media complex (IMC) value of more than 30.43 μm. Results. Among clinical and laboratory risk factors, an increase in systolic blood pressure has a statistically signifi cant effect on the likelihood of increasing IMC (χ2-criterion = 5.76, p = 0.016), arterial hypertension stage (χ2-criterion = 9.45, p = 0.002), blood urea level (χ2-criterion = 8.11, p = 0.004), decrease in glomerular fi ltration rate (χ2-criterion = 5.0, p = 0.025), increase in the stage of chronic kidney disease (χ2-criterion = 10.32, p = 0.001). The presence of signs of GN progression, such as an increase in erythrocyte sedimentation rate (ESR) or proteinuria, did not have a statistically significant effect on the risk of IA remodeling (p>0.05). The increase in IA IMC is affected by the presence of hyalinosis of glomerular capillary loops (χ2-criterion = 7.56, p = 0.006), periglomerular hyalinosis (χ2-criterion = 6.96, p = 0.008), sclerosis of the glomerulus (χ2-criterion = 3.9, p = 0.048), increased fibrosis of tubulointerstitium (χ2-criterion = 12.16, p = 0.0005). Conclusion. In GN and AH, remodeling of small-diameter renal vessels occurs due to the influence of AH and its severity, tubulointerstitial changes in the renal tissue. New risk factors for vascular remodeling have been obtained — changes in the glomerulus. At the same time, the inflammatory and autoimmune mechanisms of GN were not associated with changes in the vascular wall. The role of hypertension is decisive in changing the structure of small-diameter kidneys.

Published: February 2024

Nigeria’s Electoral Act 2022 legitimises the use of technology in different aspects of the electoral process. The steady increase in technology adoption in the electoral process continued in 2023, after successful pilots in the Anambra, Ekiti, and Osun state elections.

Political vigilante violence in Ghana: its human rights implications
Authors: Twendeboah Seth , Nangwele Linus , Baami Paul Akwasi
Published: February 2024

The primary goal of this paper is to consider the incontrovertible links between political vigilante violence and human rights violations in Ghana. In particular, it pays attention to the ways in which politically-related violence thrives. To achieve this, the paper will be guided by the following research objectives: First, to explore the nature of political vigilantism in Ghana’s Fourth Republic. Second, to analyse the human rights issues in political vigilantism within this period. Drawing mainly on experiences of general elections of Ghana’s Fourth Republic, the paper purposes to interrogate the scale of political vigilante violence in Ghana. It contends that there is an intricate link between political vigilante violence and human rights. The paper relies on frustration-aggression theory to consider the ways in which the desire to gain political power leads to rivalry and eventually to violence.
Finding an Unique and “Natural” Extension of the Expected Value That Is Finite for All Functions in Non-Shy Subset of the Set of All Measurable Functions
Authors: Krishnan Bharath
Published: February 2024

Suppose for n∈ ℕ, set A⊆ℝⁿ and function f∶A→ℝⁿ. If set A is Borel; we want to find an unique and “natural” extension of the expected value, w.r.t the Hausdorff measure on bounded functions to unbounded/bounded f, that's finite for all f in a non-shy subset of B*---the set of all Borel measurable functions in ℝᴬ. The issue is current extensions of the expected value are finite for all functions in only a shy subset of B*. The reason this issue wasn't resolved is mathematicians have not thought of the problem, focusing on application rather than generalization. Despite the lack of potential use, we'll attempt to solve the problem by defining a choice function---this shall choose a unique set of equivalent sequences of sets (Fₖ***) , where the set-theoretic limit of Fₖ*** is the graph of f; the measure Hʰ is the ℎ-Hausdorff measure, such for each k∈ℕ, 0 < Hʰ(Fₖ***) < +∞; and (fₖ*) is a sequence of functions where {(x₁,...,xₙ,fₖ*(x₁,...,xₙ))∶x∈ dom(Fₖ***)}=Fₖ***. Thus, if (Fₖ***) converges to A at a rate linear or super-linear to the rate non-equivelant sequences of sets converge, the extended expected value of or E**[f,Fₖ***] is: ∀(ε>0)∃(N∈ℕ)∀(k∈N)(k≥N⇒1/Hʰ(dom(Fₖ***))∫dom(Fₖ*** )fₖ* dHʰ - E**[f,Fₖ***]<ε ) which should be unique and “natural” extension for all f in a non-shy subset of B*. Note we guessed the choice function using computer programming but we don’t use mathematical proofs due to the lack of expertise in the subject matter. Despite this, the biggest use of this research is the extension of the expected value is finite for "almost all" functions: this is easier to use in application when finding the "average" of functions covering an infinite expanse of space.
The Hidden Loopholes Undermining Photonic Quantum Nonlocality: Quantum Rayleigh Scattering and Time-Dependent Multi-photon Pure States of Independent Photons
Authors: Vatarescu Andre
Published: February 2024

The locality condition of probabilities underpinning the derivation of Bell inequalities can be violated classically. The wave function collapse results in the factorization of quantum probabilities. It is possible to differentiate, locally, between ensemble probabilities of single detections with and without wave function collapse for the alleged quantum nonlocality. The theoretical concept of photonic quantum nonlocality cannot be implemented physically because of the quantum Rayleigh scattering of single photons. A distinction needs to be made between the correlation of individual, single measurements of pure states and the correlation of the ensemble states of the mixed states. The correlation operator of Pauli vector operators delivers the same probabilities of correlated detections of photons for both independent and multi-photon states as for ‘entangled’ states of photons. As single-photon sources are not needed, the design and implementation of quantum computing operations and other devices will be significantly streamlined.

The Improvement of the Use of Open Data in Public Institutions
Authors: Hyseni Besart , Bexheti Lejla Abazi
Published: February 2024

The study investigated the usage of open data in public organizations, focusing on the motives, preferences, and governance ideals that determine their quality. The study shed light on how open data platforms are created and improved, as well as their influence on government operations. The primary goal was to understand the motivations behind the usage of open data, evaluate gov-ernance ideals, and examine institutions' efforts to standardize data formats. Hierarchical regres-sion analysis divides variables into core reasons and different preferences, demonstrating a need for "diversification" in order to use open data effectively. Efficiency, accountability, community impact, knowledge, and high-quality service delivery are all emphasized in governance value analysis. The institution's dedication to standardizing open data formats is evidenced by legislative measures and the integration of many technologies. The findings illustrate the institution's dual strategy of em-ploying traditional techniques and new technologies for effective data management. The report suggests increasing data openness and standardization, investing in ongoing training, upgrading alerting and awareness systems, and adopting specific regulations for open data use. Monitoring and feedback techniques are critical for adjusting and refining open data services to satisfy de-velopment needs. This study adds to the scientific knowledge of open data use by highlighting important motives, preferences, and governance ideals. The offered guidelines provide practical insights for public organizations looking to improve their open data platforms by promoting openness, efficiency, and community participation.
Mucosal mRNA Vaccines. Merits and Perspectives
Authors: Toniolo Antonio Quirino , Maccari Giuseppe , Camussi Giovanni
Published: February 2024

This review highlights the potential and limitations of mRNA vaccines with a particular focus on mucosal delivery as an alternative to parenteral administration. The strengths of mRNA vaccines are: a) Versatility: they can be adapted to target a wide range of pathogens; b) Faster development: designed and produced more quickly than traditional vaccines; c) High efficacy: effective in preventing severe disease, as demonstrated during the COVID-19 pandemic. Current challenges: a) Delivery: current methods (mainly intramuscular injection) may not be optimal for inducing mucosal immunity; b) Stability: mRNA is fragile and needs to be protected from degradation; c) Safety: potential side effects, including myocarditis, blood clotting, allergic reactions need further investigation. Mucosal delivery could be more effective in preventing the transmission of pathogens and is generally better accepted by the population. Pros: offers the potential to induce local immunity at the site of pathogen entry, potentially providing broader protection; Cons: developing effective delivery systems and adjuvants for mucosal delivery is difficult. Extracellular vesicles as a mucosal delivery system are promising and offer a potentially safe, scalable, and needle-free approach. Future directions: a) Optimizing mRNA constructs: strategies like codon optimization and self-amplifying RNA can improve stability and translation efficiency; b) Rigorous pre-clinical studies are essential before human trials.
Long-Term Effect of Fire on Leaf Production in a Southwest Missouri Oak Woodland

Published: February 2024

Missouri Ozark woodlands are a unique but imperiled ecosystem type because of fragmentation, lack of proper management and a changing climate. Management, restoration and conservation of Ozark woodlands is a conservation priority. The ecosystem services provided by Ozark woodlands include carbon and nutrient sequestration via primary productivity. We have assessed over- and mid-story leaf production, collecting leaves in baskets every fall, in a 1,200ha conservation area in SW Missouri since 2000. Leaf production data from 2000 to 2020 was compared among sites; control, burned (periodically burned) and reference (continuously burned). Average oak leaf production was high in the burned while the other leaf production was high in control. Sapling density of oak was found high in the burned site compared to the other sites. We applied the regression among productivity, temperature, and precipitation. Reference site showed a statistical significance with the precipitation but not with the temperature. While other sites did not show any statistical significance with the precipitation. No statistically significance difference in effect was observed between the productivity and temperature on any sites. March-June, March-May and June-August precipitation showed a statistically significant difference with the productivity while the other average precipitation and temperature showed no statistical significance.
