description: For systems of three identical particles in which short-range forces produce shallow two-particle bound states, and in particular for the ``pion-less'' Effective Field Theory of Nuclear Physics, I extend and systematise the power-counting of three-body forces to all partial-waves and orders, including external currents. With low-energy observables independent of the details of short-distance dynamics, the typical strength of a three-body force is determined from the superficial degree of divergence of the three-body diagrams which contain only two-body forces. This naïve dimensional analysis must be amended as the asymptotic solution to the leading-order Faddeev equation depends for large off-shell momenta crucially on the partial wave and spin-combination of the system. It is shown by analytic construction to be weaker in most channels with angular momentum smaller than 3 than expected. This demotes many three-nucleon forces to high orders. Observables like the quartet-S-scattering length are less sensitive to three-nucleon forces than guessed. I also comment on the Efimov effect and limit-cycle for non-zero angular momentum.

description: This study explored the inter-communal interactions, and causes, actors, and effects of the 2019-2020 violent conflict of the Karrayyu pastoralists with the Itu farming and agropastoral community in Fentalle District of East Shoa Zone of Oromia. It was conducted based on qualitative data generated through interviews, focus group discussions and non-participatory observations. Both primary and secondary sources were used. Results of this study showed that despite the recent violent conflict, the two communities have far-reaching history of inter-communal solidarity, resource sharing, economic and marriage interactions, kins confederation and joint Gadaa parties. The shrinkage of pasture lands, disgracing and degradation of “lafa jiinfuu” (sacred natural sites), and a growing herder-farmer and agropastoral tension are explored as the major causes that have fostered conditions conducive to conflict generation and intensification since recent years. The analysis highlighted homicide and blockage of the road to Karrayyu’s “lafa jiinfuu” as the proximate causes of the conflict. To this end, the violent conflict had brought humanitarian, economic, social and security effects on both communities. Thus, we recommend that the Federal and Oromia regional state governments, nongovernmental organizations, and customary institutions, should intensify efforts to build inter-communal peace by ensuring the rule of law, and also through public enlightenment, education, and campaign for peaceful coexistence in the study area.

description: In this study, we investigate out-of-time-order correlators (OTOCs) in systems with power-law decaying interactions such as $R^{-α}$, where $R$ is the distance. In such systems, the fast scrambling of quantum information or the exponential growth of information propagation can potentially occur according to the decay rate $α$. In this regard, a crucial open challenge is to identify the optimal condition for $α$ such that fast scrambling cannot occur. In this study, we disprove fast scrambling in generic long-range interacting systems with $α>D$ ($D$: spatial dimension), where the total energy is extensive in terms of system size and the thermodynamic limit is well-defined. We rigorously demonstrate that the OTOC shows a polynomial growth over time as long as $α>D$ and the necessary scrambling time over a distance $R$ is larger than $t\gtrsim R^{\frac{2α-2D}{2α-D+1}}$.

Ethno-Linguistic Federalism in Ethiopia: Opportunity or Threat to National Unity?
Creators: name: Deme, Kena
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: Even if Ethiopia is left without a single choice other than introducing the federal political system, it did not escape criticisms. Especially, as far as national unity is concerned, there are strong opposing views- the pro-unitary state and the pro-multiethnic federal system. This study is aimed at examining whether the so far ethno-linguistic federalism experience of the country has been contributing to national unity as well as national consensus or not. To this end, the study relied on secondary sources. Based on a systematic analysis of relevant sources, the following findings are obtained. Though the proponents of pro-unitary system are of the opinion that the current federal system which at least constitutionally gives equal footing to ethnic groups is against the national unity of Ethiopia, this study shows that it is not ethnic federalism that is a barrier to national unity but there are diverse factors. These factors include, but not limited to, unbalanced interest of ethnic groups' elites, inadequacy of commitment to ethno-linguistic federalism principle, lack of constitutionalism and misconception of ethno-nationalism. It is true that the popular struggle for real autonomy and self-rule on one hand and the division or confusion regarding the Ethiopian national unity on the other hand has continued. This study suggests that acknowledging past injustices, practicing ethno-linguistic federalism principle genuinely and foreseeing reciprocated fate are imperative for building national unity and national consensus in Ethiopia where all ethnic groups’ identity is treated equally.

Creators: name: Damtew, Ali
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: This paper deals with marital names given to bride in traditional marriage of South Wollo Zone. The research was necessary to be conducted because transmitting meaningful names given reasonably to bride from generation to generation is under threat because of modernity. To collect data, the researcher employed focus-group discussion, non-structured interview and open-ended questions. For this study, data was collected from six districts of South Wollo Zone, such as Tänta, Mäk’ïdäla, Kutabär, Läganbo, Däse Zuriya and K’alu. Both sexes (male and female) were participants of the study. Purposive sampling was employed to select the areas and the participants of the study. Qualitative data analysis method was used to interpret and analyze names of bride. The paper finds out names given to a bride and revealed sociolinguistic issues which motivate those who give names and the meaning of the names given. The names given to bride are grouped based on the meanings or the themes they imply. The aspects or factors behind the names of the bride are hopes, weakness, happiness, wishes, loneliness, lack, and fear of the name- givers, honor, beauty, industriousness, good behavior, sociability, kindness, generosity, protection, fortune of the bride. Furthermore, precious materials, traditions, body parts and flora are also taken into account to give names for a bride. Finally, further research is recommended to be carried out in the rest of the districts of Wollo and other areas of the Amhara regional state to find out names given to brides after their marriage.

description: The purpose of this study was exploring the facilitators’ attitude and engagement in advocacy towards inclusion of adults with disabilities in the integrated functional adult education program (IFAEP) in Gedeo Zone, Ethiopia. To this end, the explanatory sequential design which belongs to the mixed methods approach was employed. A total of 214 facilitators were selected using stratified random sampling to fill out the questionnaire with 98.6% (211) response rate. Three respondent facilitators were selected using purposive sampling technique for an interview based on their active participation in IFAEP. The quantitative data were analyzed using SPSS version 23 and presented through mean, SD, percentage, independent sample t-test, Mann-Whitney Test and Pearson correlation while the qualitative data were analyzed through narrative analysis. The quantitative results revealed that the majority of facilitators’ had positive attitude and demonstrated the highest engagement in advocacy towards inclusion of adults with disabilities in IFAEP. Among the demographic characteristics, a statistically significant mean score difference was observed in facilitators’ educational qualification but not in other demographic characteristics. The Pearson’s correlation coefficient (r= .655**) indicated that facilitators’ attitude and their engagement in advocacy were positively correlated. The qualitative results also revealed that facilitators’ had positive attitude and demonstrated the highest engagement in advocacy. Changes in facilitators’ attitude can bring about changes in their engagement in advocacy towards inclusion of adults with disabilities in IFAEP. It is recommended that facilitators’ educational qualification should be improved for the effective inclusion of adults with disabilities in IFAEP.

Relational Coping Resources: Caregiver Families’ Experience of Living with Chronic Illness in Addis Ababa, Ethiopia: A Phenomenological Study
Creators: name: Fikre, Kaleab
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: Caregiver families of chronically ill members usually experience chaos. They, however, often use strategies to manage, cope with, and mitigate the negative effects of the illness. Therefore, this study aimed at revealing relational coping resources that caregiver families use to cope with and mitigate the effects of living with chronically ill family members. The study was purely qualitative. It employed a phenomenological method. Participants were caregiver families who had a family member with a chronic illness. The data was collected from 20 interviewees using semi-structured interview-guiding questions and analyzed it thematically. The findings revealed that relational resources emanated from a family's religious affiliation and friendships provide opportunities to enhance coping capacities, which in turn facilitated and helped in coping with and mitigating the effects of illness. Moreover, a strong sense of We-ness produced by familial relationships plays an important role in strengthening the family's coping capacity. Relational coping resources enhance maintaining the family's social relationships, obtain social support, and provide a sense of unity within the family. In the absence of formal supports, such as family counseling, this study argues that informal relational coping resources play a critical role in mitigating the effects of the illness. Despite its debilitating effects, the family experiences of chronic illnesses received little attention in hospitals. In conclusion, the study recommends that hospitals need to establish mechanisms to support families living with chronic illness, which could raise their awareness and help them, cope with the challenges that the illness brings.

description: We present near-infrared $J$, $H$, and $K$ images of four embedded stellar clusters in the Galaxy. We find a significant fraction of pre-main-sequence stars present in at least one of the clusters. For the clusters dominated by main-sequence stars, we determine the initial mass function (IMF) both by using the $K$ luminosity function and a global extinction correction and by deriving individual extinction corrections for each star based on their placement in the $K$ vs. $H-K$ color-magnitude diagram. Based on our IMFs we find a significant discrepancy between the mean IMF derived via the different methods, suggesting that taking individual extinctions into account is necessary to correctly derive the IMF for an embedded cluster.

description: The strong light-matter optomechanical coupling offered by Coherent Scattering (CS) set-ups have allowed the experimental realisation of quantum ground state cavity cooling of the axial motion of a levitated nanoparticle [U. Delić et al., Science 367, 892 (2020)]. An appealing milestone is now quantum 2D cooling of the full in-plane motion, in any direction in the transverse plane. By a simple adjustment of the trap polarisation, one obtains two nearly equivalent modes, with similar frequencies $ω_{x}\simω_{y}$ and optomechanical couplings $g_{x}\simeq g_{y}$ -- in this experimental configuration we identify an optimal trap ellipticity, nanosphere size and cavity linewidth which allows for efficient 2D cooling. Moreover, we find that 2D cooling to occupancies $n_{x}+n_{y}\lesssim1$ at moderate vacuum ($10^{-6}$ mbar) is possible in a "Goldilocks" zone bounded by $\sqrt{κΓ/4}\lesssim g_{x},g_{y}\lesssim|ω_{x}-ω_{y}|\lesssimκ$, where one balances the need to suppress dark modes whilst avoiding far-detuning of either mode or low cooperativities, and $κ$ ($Γ$) is the cavity decay rate (motional heating rate). With strong-coupling regimes $g_{x},g_{y}\gtrsimκ$ in view one must consider the genuine three-way hybridisation between $x$, $y$ and the cavity light mode resulting in hybridized bright/dark modes. Finally, we show that bright/dark modes in the levitated set-up have a simple geometrical interpretation, related by rotations in the transverse plane, with implications for directional sensing.

description: The leading term of the asymptotic of quasinormal modes in the Schwarzschild background, omega_n = - i n/2, is obtained in two straightforward analytical ways for arbitrary spins. One of these approaches requires almost no calculations. As simply we demonstrate that for any odd integer spin, described by the Teukolsky equation, the first correction to the leading term vanishes. Then, this correction for half-integer spins is obtained in a slightly more intricate way. At last, we derive analytically the general expression for the first correction for all spins, described by the Teukolsky equation.

description: A method of random forcing with a constant power input for two-dimensional gyrokinetic turbulence simulations is developed for the study of stationary plasma turbulence. The property that the forcing term injects the energy at a constant rate enables to set up turbulence in the desired range and to quantitatively assess energy dissipation channels in a statistically steady state. Using the developed method, turbulences in the large scale fluid and small scale kinetic regimes are demonstrated, where the theoretically predicted scaling laws are successfully reproduced.

Challenges and Coping Mechanisms of Internally Displaced People Resettled in Adama and Sebeta Towns of Ethiopia
Creators: name: Birhanu, Alemneh
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: This study aimed to give perceptiveness into the challenges faced by internally displaced people (IDP) who are dislocated from the Somali region and their coping experience. The study employed both qualitative (using in-depth interview, key informant interview, FGD and observation) and quantitative (using questionnaire) research approaches. A sample of 610 respondents was selected through a systematic random sampling technique to ensure the representativeness of the data. Descriptive statistics and thematic analysis were used to analyze the data. The findings of the study revealed that there were several challenges faced by IDP uprooted from the Somali region and currently resettled in Adama and Sebeta towns. Some of the most common challenges experienced by the IDP were food insecurity, lack of health care, housing problem, lack of income-generating sources, unemployment, and family separation. These findings confirmed that shortage of food and malnutrition were serious problems for the IDP. Results from this study further indicated that, even though they have encountered various challenges, they have attempted to employ different mechanisms to overcome their hardships. The study recommends that the federal government and regional governments are expected to consistently implement a dependable legal and institutional framework for the control of internal displacement and provision of necessary support for the displaced people.

The Muka-Laafaa: The Image of Oromo Women under the Gadaa System and Its Implications for Peace
Creators: name: Imana, Gutema
Publisher: name: East African Journal of Social Sciences and Humanities
Year: 2022

description: This article aims at addressing the image of Oromo women under the Gadaa system and its implications for societal peace. Women were referred to as Muka-laafaa (softwood) in Oromo society and this term or concept is the centre of focus in this article. Descriptive and narrative research designs were employed for the research and primary data were collected through key informant interviews while relevant secondary data were collected from secondary sources. The collected data were carefully analyzed and interpreted after crosschecking and classifying them into themes. The study revealed that the Oromo women (the muka-laafaas) were fairly treated socially, politically, and economically under the Gadaa system; particularly during its golden age which disproves the view that the Gadaa system is a patriarchal system that has never entertained issues of gender balance. The Gadaa system faced internal and external challenges beginning from the second half of the 19th century. With this, the fate of the Oromo women entered a gloomy phase as the harmful changes loaded the existing patriarchal tendencies with total energy. Therefore, the study recommends that lessons need to be learned from models of societal life used during the golden age of the Gadaa system to improve today’s gender relations in the Oromo society for peaceful coexistence between men and women.

description: We figure out the famous Klein's paradox arising from the reflection problem when a Dirac particle encounters a step potential with infinite width. The key is to piecewise solve Dirac equation in such a way that in the region where the particle's energy E is greater (less) than the potential V, the solution of the positive (negative) energy branch is adopted. In the case of Klein-Gordon equation with a piecewise constant potential, the equation is decoupled to positive and negative energy equations, and reflection problem is solved in the same way. Both infinitely and finitely wide potentials are considered. The reflection coefficient never exceeds 1. The results are applied to discuss the transmissions of particles with no mass or with very small mass.

Year: 2022

description: This study explored the skills mismatch of Technical and Vocational Education and Training and the expected competency of the employees as perceived by private firms in Addis Ababa. A concurrent mixed-method research design was used. In this study, 21 respondents for the Key Informant Interview and 233 respondents for the questionnaire have taken part. The sample respondents were drawn from 17 firms in Addis Ababa, using purposive and simple random sampling techniques. Data was collected using the STEP Skills Measurement Employer Survey and adapted to the local context, and a structured interview guide. The quantitative data were analyzed using descriptive statistics such as mean, Standard Deviation (SD), graphs, and inferential statistics such as one-way ANOVA. In contrast, the qualitative data were analyzed using thematic analysis. Finally, the ANOVA results unveiled the most incredible skills mismatch between what employers consider relevant to their firms and the technical and vocational education and training graduates competencies in general, soft and hard skills. Thus, strengthening the links between the technical and vocational education and training colleges and employers are recommended.

description: This paper is dedicated to clarifying and introducing the correct application of Melnikov method in fractional dynamics. Attention to the complex dynamics of hyperbolic orbits and to fractional calculus can be, respectively, traced back to Poincarés attack on the three-body problem a century ago and to the early days of calculus three centuries ago. Nowadays, fractional calculus has been widely applied in modeling dynamic problems across various fields due to its advantages in describing problems with non-locality. Some of these models have also been confirmed to exhibit hyperbolic orbit dynamics, and recently, they have been extensively studied based on Melnikov method, an analytical approach for homoclinic and heteroclinic orbit dynamics. Despite its decade-long application in fractional dynamics, there is a universal problem in these applications that remains to be clarified, i.e., defining fractional-order systems within finite memory boundaries leads to the neglect of perturbation calculation for parts of the stable and unstable manifolds in Melnikov analysis. After clarifying and redefining the problem, a rigorous analytical case is provided for reference. Unlike existing results, the Melnikov criterion here is derived in a globally closed form, which was previously considered unobtainable due to difficulties in the analysis of fractional-order perturbations characterized by convolution integrals with power-law type singular kernels. Finally, numerical methods are employed to verify the derived Melnikov criterion. Overall, the clarification for the problem and the presented case are expected to provide insights for future research in this topic.

Machine Learning of Free Energies in Chemical Compound Space Using Ensemble Representations: Reaching Experimental Uncertainty for Solvation

description: Free energies govern the behavior of soft and liquid matter, and improving their predictions could have a large impact on the development of drugs, electrolytes or homogeneous catalysts. Unfortunately, it is challenging to devise an accurate description of effects governing solvation such as hydrogen-bonding, van der Waals interactions, or conformational sampling. We present a Free energy Machine Learning (FML) model applicable throughout chemical compound space and based on a representation that employs Boltzmann averages to account for an approximated sampling of configurational space. Using the FreeSolv database, FML's out-of-sample prediction errors of experimental hydration free energies decay systematically with training set size, and experimental uncertainty (0.6 kcal/mol) is reached after training on 490 molecules (80\% of FreeSolv). Corresponding FML model errors are also on par with state-of-the art physics based approaches. To generate the input representation for a new query compound, FML requires approximate and short molecular dynamics runs. We showcase its usefulness through analysis of FML solvation free energies for 116k organic molecules (all force-field compatible molecules in QM9 database) identifying the most and least solvated systems, and rediscovering quasi-linear structure property relationships in terms of simple descriptors such as hydrogen-bond donors, number of NH or OH groups, number of oxygen atoms in hydrocarbons, and number of heavy atoms. FML's accuracy is maximal when the temperature used for the molecular dynamics simulation to generate averaged input representation samples in training is the same as for the query compounds. The sampling time for the representation converges rapidly with respect to the prediction error.

description: The impact of written feedback on students' ability to improve their writing accuracy has long been a point of debate. This study aimed to investigate the effects of direct and indirect feedback strategies on grade 11 EFL (English as a Foreign Language) students’ paragraph writing performance at Abdisa Aga Secondary School in order to develop a feedback provision model. The study was a quasi-experiment in design. Three sections were selected randomly from the seven sections and then allocated as treatments and control group (Sections E and F, and Section G, respectively). A proficiency test (as a pre-test and post-test) was used to collect quantitative data, which was then analyzed using a two-tailed t-test. Furthermore, an Independent Sample t-test was used to compare the mean results of the proficiency test of the direct, indirect, and control groups, while a one-way ANOVA was used to compare the means of the direct, indirect, and control groups based on their writing performance. The finding shows that the students in the treatment groups outperformed the students in the control group in their writing performance. However, there is no significant mean difference between the direct and indirect groups’ scores. The use of direct and indirect feedback as an intervention had a significant positive effect on writing. The results obtained from the proficiency tests indicate that experimental groups have improved aspects of writing. Thus, Abdisa Aga Secondary School teachers should apply direct and indirect feedback in the EFL classroom.

description: In this review paper we consider the polynuclear growth (PNG) model in one spatial dimension and its relation to random matrix ensembles. For curved and flat growth the scaling functions of the surface fluctuations coincide with limit distribution functions coming from certain Gaussian ensembles of random matrices. This connection can be explained via point processes associated to the PNG model and the random matrices ensemble by an extension to the multilayer PNG and multi-matrix models, respectively. We also explain other models which are equivalent to the PNG model: directed polymers, the longest increasing subsequence problem, Young tableaux, a directed percolation model, kink-antikink gas, and Hammersley process.

description: A shape-function independent relation is derived between the partial B->X_u+l+nu decay rate with a cut on P_+=E_X-P_XX_s+gamma photon-energy spectrum. The leading-power contribution to the weight function is calculated at next-to-next-to-leading order in renormalization-group improved perturbation theory, including exact two-loop matching corrections at the scale mu_i^2 ~ m_b*Lambda_{QCD}. The overall normalization of the weight function is obtained up to yet unknown corrections of order [alpha_s(m_b)]^2. Power corrections from phase-space factors are included exactly, while the remaining subleading contributions are included at first order in 1/m_b. At this level unavoidable hadronic uncertainties enter, which are estimated in a conservative way. The combined theoretical accuracy in the extraction of |V_{ub}| is at the level of 5% if a value of Delta near the charm threshold can be achieved experimentally.

description: Scientific literature contains large volumes of complex, unstructured figures that are compound in nature (i.e. composed of multiple images, graphs, and drawings). Separation of these compound figures is critical for information retrieval from these figures. In this paper, we propose a new strategy for compound figure separation, which decomposes the compound figures into constituent subfigures while preserving the association between the subfigures and their respective caption components. We propose a two-stage framework to address the proposed compound figure separation problem. In particular, the subfigure label detection module detects all subfigure labels in the first stage. Then, in the subfigure detection module, the detected subfigure labels help to detect the subfigures by optimizing the feature selection process and providing the global layout information as extra features. Extensive experiments are conducted to validate the effectiveness and superiority of the proposed framework, which improves the detection precision by 9%.

description: We derive a theorem for the lower bound on the energy dissipation rate by a rigid surface-driven active microswimmer of arbitrary shape in a fluid at low Reynolds number. We show that, for any swimmer, the minimum dissipation at a given velocity can be expressed in terms of the resistance tensors of two passive bodies of the same shape with a no-slip and perfect-slip boundary. To achieve the absolute minimum dissipation, the optimal swimmer needs a surface velocity profile that corresponds to the flow around the perfect-slip body, and a propulsive force density that corresponds to the no-slip body. Using this theorem, we propose an alternative definition of the energetic efficiency of microswimmers that, unlike the commonly-used Lighthill efficiency, can never exceed unity. We validate the theory by calculating the efficiency limits of spheroidal swimmers.

Clinical and molecular analysis of Williams-Beuren syndrome : a search for factors determining clinical variability in a contiguous deletion syndrome
Creators: name: Wang, Michael Steve

description: Williams-Beuren syndrome (WBS) is clinically characterized by a distinctive "elfin" facial appearance, short stature, mental retardation, a unique cognitive profile, friendly outgoing personality, and various congenital heart malformations with supravalvular aortic stenosis (SVAS) being the most common. Clinical features seen with less frequency include infantile hypercalcaemia, hoarse voice, hyperacousis, renal hypoplasia, clinodactyly of the 5th finger, and teeth hypoplasia. The syndrome arises as a consequence of a 2 cM deletion of 7qll.23 in 90 - 95% of all clinically typical cases reported to date. This region includes a number of genes that include elastin (ELN) and LEVI kinase 1 (LTMK1). ELN mutations have been found in isolated cases of SVAS while LIMK1 has been implicated in the unique WBS cognitive profile. However, not all patients present with congenital cardiovascular malformations and the severity to which cognition is impaired in WBS individuals varies with each patient. This variability of clinical phenotype presentation in clinically typical cases has not been explained. In order to identify the underlying cause of this variability, clinical and molecular data were analyzed from 108 clinically diagnosed WBS cases. A deletion of 7qll.23 was identified in 85 cases and extended from D7S489U to D7S1870 (including these markers) in the majority of cases. Only two cases were found to have a more distal deletion that also encompassed D7S489L. In these 85 cases, no influence on phenotypic variability was found for deletion extent, parental origin of deletion, ELN and LLMK1 polymorphisms, or gender using a Bonferroni corrected level of significance (α'=4.6x10⁻⁴). Nonetheless, a number of interesting 'suggestive' associations with p<0.05 were identified. Correlations between clinical features of WBS were examined to identify those features which may have a common etiology. Identifying correlates may also identify specific phenotypic features that can be used as a prognostic tool. This has revealed significant correlations between: 1) low birth weight (<10th centile) and low weight at the time of physical examination (<10th centile at the time of examination; p=9.0xl0⁻⁵), and 2) hypercalcemia and presentation of a stellate iris pattern (p=1.0xl0⁻⁵). While not fulfilling the strict criterion (α '=3.3xl0⁻⁴) necessary to reach an experiment-wide false positive rate of less than 5%, a number of interesting suggestive correlations were observed including: 1) stellate and blue irides (p=1.2xl0⁻³), 2) stellate irides and a typical WBS personality (p=6.8xl0⁻³), and 3) renal/urogenital abnormalities and cardiovascular malformations (p=7.9xl0⁻³). These identified associations provide an important starting point for the understanding of the underlying etiology of WBS and will be of interest to confirm in an independent data set.

description: We present a method to search for transient GWs using a network of detectors with different spectral and directional sensitivities: the interferometer Virgo and the bar detector AURIGA. The data analysis method is based on the measurements of the correlated energy in the network by means of a weighted cross-correlation. To limit the computational load, this coherent analysis step is performed around time-frequency coincident triggers selected by an excess power event trigger generator tuned at low thresholds. The final selection of GW candidates is performed by a combined cut on the correlated energy and on the significance as measured by the event trigger generator. The method has been tested on one day of data of AURIGA and Virgo during September 2005. The outcomes are compared to the results of a stand-alone time-frequency coincidence search. We discuss the advantages and the limits of this approach, in view of a possible future joint search between AURIGA and one interferometric detector.

description: Polyvinylidene difluoride (PVDF) is a ferroelectric polymer characterized by negative strain along the direction of the applied electric field. However, the electromechanical response mechanism of PVDF remains unclear due to the complexity of the hierarchical structure across the length scales. As described in this letter, we employ the Finsler geometry model as a new solution to the aforementioned problem and demonstrate that the deformations observed through Monte Carlo simulations on 3D tetrahedral lattices are nearly identical to those of real PVDF. Specifically, the simulated mechanical deformation and polarization are similar to those observed experimentally.
