description: We report on a possibility of measuring parity violating effects in radiative neutrino pair emission from metastable atoms; asymmetric angular distribution of emitted photons from oriented atoms and emergent circular polarization. Their observation, along with the continuous photon energy spectrum which has 6 thresholds, may be interpreted as events being a combined weak and QED process, emission of $γν_i ν_j$ in the final state. The method may greatly help to perform neutrino mass spectroscopy using atoms, a systematic determination of the neutrino mass matrix.

description: We study the coherent exciton transport on Apollonian networks generated by simple iterative rules. The coherent exciton dynamics is modeled by continuous-time quantum walks and we calculate the transition probabilities between two nodes of the networks. We find that the transport depends on the initial nodes of the excitation. For networks less than the second generation the coherent transport shows perfect revivals when the initial excitation starts at the central node. For networks of higher generation, the transport only shows partial revivals. Moreover, we find that the excitation is most likely to be found at the initial nodes while the coherent transport to other nodes has a very low probability. In the long time limit, the transition probabilities show characteristic patterns with identical values of limiting probabilities. Finally, the dynamics of quantum transport are compared with the classical transport modeled by continuous-time random walks.

description: We consider the problem of sound propagation in a wind. We note that the rays, as in the absence of a wind, are given by Fermat's principle and show how to map them to the trajectories of a charged particle moving in a magnetic field on a curved space. For the specific case of sound propagating in a stratified atmosphere with a small wind speed we show that the corresponding particle moves in a constant magnetic field on the hyperbolic plane. In this way we give a simple `straightedge and compass' method to estimate the intensity of sound upwind and downwind. We construct Mach envelopes for moving sources. Finally, we relate the problem to that of finding null geodesics in a squashed anti-de Sitter spacetime and discuss the $SO(3,1)\times \mathbb{R}$ symmetry of the problem from this point of view.

description: The recent results of the Pierre Auger Observatory on the possible correlation of Ultra High Energy Cosmic Rays events and several nearby discrete sources could be the starting point of a new era with charged particles astronomy. In this paper we introduce a simple model to determine the effects of any local distribution of sources on the expected flux. We consider two populations of sources: faraway sources uniformly distributed and local point sources. We study the effects on the expected flux of the local distribution of sources, referring also to the set of astrophysical objects whose correlation with the Auger events is experimentally claimed.

description: Feacal sludge (FS) management is a growing concern in the Global South. Research has shown that FS has a potential for reuse in agriculture due to its high nutrient content. However, it contains many pathogens which present a public health and environmental risks when it is applied to land without proper treatment. Composting is one of the viable options for sanitizing FS biosolids before reuse in agriculture as a soil conditioner. However, pathogen die-off during FS composting and factors responsible for pathogen survival in compost are not well understood. Therefore, we conducted a systematic review to better understand pathogen inactivation during FS composting. The results revealed that although most pathogens are inactivated by the temperature generated during composting, spore-forming bacteria, helminths, and viruses are likely to survive the process. The findings indicated that although temperature-time is the major factor responsible for pathogen inactivation during composting, other factors (change in pH, moisture content, turning frequency, nutrient depletion, toxic by-products) and mechanisms (indigenous microbial activities, microbial antagonistic effect, antibiotic action) also have an influence. In addition, most studies on pathogen inactivation during FS composting are usually based on the use of indicator microorganisms and there are limited studies on specific pathogens. Hence, further research on virus, protozoa and antimicrobial resistance inactivation during FS composting as well as the role of factors and mechanisms involved in the composting process is needed. This research will generate vital formation to inform the design, operation, and optimization of FS composting facilities to produce pathogen-free compost.

The aim of this investigation is to expand the horizon of scenario-based planning through computational models that are able to aid the analyst in the planning process. The investigation builds upon the advances of Information and Communication Technology (ICT) to create a novel, flexible and customizable computational capability-based planning methodology that is practical and theoretically sound. We will show how evolutionary computation, in particular evolutionary multi-objective optimization, can play a central role - both as an optimizer and as a source for innovation.

description: We propose a scheme to measure the mass of a single particle using the nonlinear response of a 2D nanoresonator with degenerate eigenmodes. Using numerical and analytical calculations, we show that by driving a square graphene nanoresonator into the nonlinear regime, simultaneous determination of the mass and position of an added particle is possible. Moreover, this scheme only requires measurements in a narrow frequency band near the fundamental resonance.

description: The status of the Greisen-Zatsepin-Kuzmin (GZK) cutoff and pair-production dip in Ultra High Energy Cosmic Rays (UHECR) is discussed.They are the features in the spectrum of protons propagating through CMB radiation in extragalactic space, and discovery of these features implies that primary particles are mostly extragalactic protons. The spectra measured by AGASA, Yakutsk, HiRes and Auger detectors are in good agreement with the pair-production dip, and HiRes data have strong evidences for the GZK cutoff. The Auger spectrum,as presented at the 30th ICRC 2007, agrees with the GZK cutoff, too. The AGASA data agree well with the beginning of the GZK cutoff at E \leq 80 EeV, but show the excess of events at higher energies, the origin of which is not understood. The difference in the absolute fluxes measured by different detectors disappears after energy shift within the systematic errors of each experiment.

description: A novel tool for tsunami wave modelling is presented. This tool has the potential of being used for operational purposes: indeed, the numerical code \VOLNA is able to handle the complete life-cycle of a tsunami (generation, propagation and run-up along the coast). The algorithm works on unstructured triangular meshes and thus can be run in arbitrary complex domains. This paper contains the detailed description of the finite volume scheme implemented in the code. The numerical treatment of the wet/dry transition is explained. This point is crucial for accurate run-up/run-down computations. Most existing tsunami codes use semi-empirical techniques at this stage, which are not always sufficient for tsunami hazard mitigation. Indeed the decision to evacuate inhabitants is based on inundation maps which are produced with this type of numerical tools. We present several realistic test cases that partially validate our algorithm. Comparisons with analytical solutions and experimental data are performed. Finally the main conclusions are outlined and the perspectives for future research presented.

description: 肝癌（Hepatocellular carcinoma,HCC）是世界死亡率第二高的癌症，全球范围内，每年大约新增62万例HCC患者，又有近60万HCC患者死亡，发病率与死亡率几乎相等。HCC最常出现在慢性病毒性肝炎（乙型肝炎或丙型肝炎）或肝硬化患者中。HCC的诊断通常取决于复杂的成像方式如CT扫描、磁共振成像（MRI）以及检测血液中α甲胎蛋白（AFP）的水平。HCC的早期发现是提供患者治愈机会的最重要因素。多年来，用于HCC检测和跟踪的首选血清学检测指标为AFP，它是HCC检测中已知的使用最广泛生物标志物。但血清AFP水平的检测存在灵敏度低和特异性低的缺点。另外，检测血清AFP浓度在HCC预后中的价值显得不足，它与HCC等肿瘤大小、分期或疾病进展的相关性并不强，而且可能存在种族差异性。在某些HCC患者中，AFP升高的并不明显。种种迹象表明，AFP其实并不是HCC早期监测的良好指标，该方法逐渐被弃用。为了改善HCC患者的治疗效果，寻找一种存在于血液中的可用于HCC早期监测且具有高灵敏度和稳定性的生物标志物显得很有必要。

虽然最近有关HCC的研究报道了一些新的基于血液的生物标志物的策略，如circulating cell-free DNA（cfDNA）；基于淋巴细胞的生物标志物，循环肿瘤细胞（CTC）和circulating miRNAs，但是这些策略的灵敏度和稳定性仍然未改善。近期研究表明，外泌体可以用于癌症诊断，这一发现为我们提供了新的思路。外泌体是由各种细胞释放出来的细胞外囊泡（EV），直径为40–150 nm。它包含多种分子，包括蛋白质，脂类和RNA。外泌体是非常稳定的，因为它的膜状结构，并且它存在于许多体液中，包括血液，唾液和尿液，这使得它可能成为潜在的诊断标记物和输送靶向药物的载体。血浆外泌体RNA包括mRNAs, microRNAs (miRNAs)和其他非编码RNAs (ncRNAs)，可以作为潜在的诊断标志物，因为它具有高稳定性和灵敏性。至今为止，仅有少数的研究报道了血浆外泌体与HCC的关系。

本项目为华大基因研究院与新加坡国立癌症研究中心（National Cancer Centre Singapore, NCCS）合作研究项目，基于健康与衰老研究所前期对200例外泌体样本的分离提取方法和技术的研究基础，由NCCS提供原发性肝癌患者样本和肝硬化患者样本，对患者血浆中外泌体源的miRNA进行分离提取，使用华大基因自主研发的BGIseq-500高通量测序仪进行测序分析，最终目标为获得外泌体源miRNA生物标记，为建立癌症的早期诊断进行初步研究。我们的研究对发现潜在的HCC生物标志物，具有重要意义。

description: In contrast to rodents, the mechanisms underlying human trophectoderm and early placenta specification are understudied due to ethical barriers and the scarcity of embryos. Recent reports have shown that human pluripotent stem cells (PSCs) can differentiate into trophectoderm (TE) - like cells (TELCs) and trophoblast stem cells (TSCs), offering a valuable in vitro model to study early placenta specification. Here, we demonstrate that the VGLL1 (vestigial- like family members 1), which is highly expressed during human and non-human primate TE specification in vivo but is negligibly expressed in mouse, is a critical regulator of cell fate determination and self-renewal in human TELCs and TSCs derived from naive PSCs. Mechanistically, VGLL1 partners with the transcription factor (TEA domain transcription factor 4) to regulate chromatin accessibility at target gene loci through histone acetylation and acts in cooperation with GATA3 and TFAP2C. Our work is relevant to understand primate early embryogenesis and how it differs from other mammalian species.

description: This study set out to explore how we might increase capacity in a community stroke service without additional resource. We explored this using a co-design approach and then implemented the proposed intervention.The intervention consisted of a change to the scope of practice for Rehabilitation Assistants, with a range of supporting strategies such as training, technology for real time clinician consultation with senior therapists and patient facing communication, that were intended to mitigate clinical risks.This change in scope of practice enabled Rehabilitation Assistants to take on more independent work with less complex patients, which allowed senior therapists to carry out more work with complex patients.This simply shift would enable more patients to flow through the service in a given period of time without increasing the workforce or increasing working hours.The work was dramatically halted by COVID, and was picked up again some time after, facing significant challenges in terms of re-igniting the effort.This report summaries the entire programme of work and reflects on the implementation and knowledge mobilisation work.
Milnor invariants and the HOMFLYPT polynomial

description: We give formulas expressing Milnor invariants of an n-component link L in the 3-sphere in terms of the HOMFLYPT polynomial as follows. If the Milnor invariant \barμ_J(L) vanishes for any sequence J with length at most k, then any Milnor \barμ-invariant \barμ_I(L) with length between 3 and 2k+1 can be represented as a combination of HOMFLYPT polynomial of knots obtained from the link by certain band sum operations. In particular, the `first non vanishing' Milnor invariants can be always represented as such a linear combination.
description: Entirely revised version (20 pages). The main result was generalized and extended to Milnor invariants of links, using new arguments. Several corollaries are given, in particular one containing the main result of the previous version. Example and References added

description: If X is the complement of a hypersurface in P^n, then Kohno showed that the nilpotent completion of the fundamental group is isomorphic to the nilpotent completion of the holonomy Lie algebra of X. When X is the complement of a hyperplane arrangement A, the ranks phi_k of the lower central series quotients of the fundamental group of X are known for isolated examples, and for two special classes: if X is hypersolvable (in which case the quadratic closure of the cohomology ring is Koszul), or if the holonomy Lie algebra decomposes in degree three as a direct product of local components. In this paper, we use the holonomy Lie algebra to obtain a formula for phi_k when A is a subarrangement of A_n. This extends Kohno's result for braid arrangements, and provides an instance of an LCS formula for arrangements which are not decomposable or hypersolvable.

description: We give a revealing expose that addresses an important issue in scattering theory of how to construct two asymptotically sinusoidal solutions of the wave equation with a phase shift using the same basis having the same boundary conditions at the origin. Analytic series representations of these solutions are obtained. In 1D, one of the solutions is an even function that behaves asymptotically as sin(x), whereas the other is an odd function, which is asymptotically cos(x). The latter vanishes at the origin whereas the derivative of the former becomes zero there. Eliminating the lowest N terms of the series makes these functions vanishingly small in an interval around the origin whose size increases with N. We employ the tools of the J-matrix method of scattering in the construction of these solutions in one and three dimensions.

description: Quantum states of light, such as squeezed states or entangled states, can be used to make measurements (metrology), produce images, and sense objects with a precision that far exceeds what is possible classically, and also exceeds what was once thought to be possible quantum mechanically. The primary idea is to exploit quantum effects to beat the shot-noise limit in metrology and the Rayleigh diffraction limit in imaging and sensing. Quantum optical metrology has received a boost in recent years with an influx of ideas from the rapidly evolving field of optical quantum information processing. Both areas of research exploit the creation and manipulation of quantum-entangled states of light. We will review some of the recent theoretical and experimental advances in this exciting new field of quantum optical metrology, focusing on examples that exploit a particular two-mode entangled photon state -- the High-N00N state.

description: Open-circuit voltages of lead-halide perovskite solar cells are improving rapidly and are approaching the thermodynamic limit. Since many different perovskite compositions with different bandgap energies are actively being investigated, it is not straightforward to compare the open-circuit voltages between these devices as long as a consistent method of referencing is missing. For the purpose of comparing open-circuit voltages and identifying outstanding values, it is imperative to use a unique, generally accepted way of calculating the thermodynamic limit, which is currently not the case. Here a meta-analysis of methods to determine the bandgap and a radiative limit for open-circuit voltage is presented. The differences between the methods are analyzed and an easily applicable approach based on the solar cell quantum efficiency as a general reference is proposed.

The Analysis of Jazz Improvisational Language and its use in Generating New Composition and Improvisation. A case study involving bebop jazz guitarist Jimmy Raney (20/8/27 - 9/5/95)
Creators: name: Hodges, GJ
Publisher: name: University Of Tasmania
Year: 2023
Subjects: Music performance

description: This project approaches the improvised music-learning environment from both practical and academic perspectives. It explores the content of Jimmy Raney’s improvisational language and how this knowledge can be utilized practically in the development of new musical material. Raney, while always noted for his technical proficiency, is now, belatedly, gaining recognition, as a most influential bebop stylist. To date, relatively little of depth has been published on his unique style. The project is divided into three sections coinciding with the conceptual framework. The first involves the selection, learning and transcription of Jimmy Raney’s improvised solos. A representative selection of twenty two of Raney’s solos was transcribed. The second is the analysis and investigation of these solos and the selection of idioms appropriate for compositional genesis. Six solos were analyzed in detail and evaluated as to style, idioms, improvisational language and technique. The third section provides practical and creative outcomes for the thesis and involves the composition and recording of eight pieces whose primary melodic motifs are derived from key idioms identified in Raney’s improvisational language. They are constructed to derive the most benefit from important aspects of Raney’s style. Both musical composition (usually with written commentary) and analysis of existing musical works have traditionally been accepted as valid research products. The composition of new works based on knowledge gained from the absorption of preexistent material consequently represents a true research outcome combining both activities. The composition and recording components ensure a focus on the artistic outcome rather than just the musicological. The works are scored in lead sheet format but are recorded in jazz style with solos and improvised extensions. Notes on the compositional process, with analysis, are included. Throughout the study a number of points of reference have been used. First, written material relating to Raney’s style and place in the development of jazz was referred to with preeminence given to sources that had close artistic association with the guitarist. After this the transcriptions and their analysis were subject to the scrutiny of proponents of jazz guitar. Lastly, the author consulted with and interviewed musicians who had a close musical association with Raney.

description: One of the most intriguing features discovered by Swift is a plateau phase in the X-ray flux decay of about 70% of the afterglows of gamma-ray bursts (GRBs). The physical origin of this feature is still being debated. We constrain the proposed interpretations, based on the intrinsic temporal properties of the plateau phase. We selected and analyzed all the Swift/XRT GRB afterglows at known redshift observed between March 2005 and June 2008 featuring a shallow decay phase in their X-ray lightcurves. For our sample of 21 GRBs we find an anticorrelation of the logarithm of the duration of the shallow phase with re dshift, with a Spearman rank-order correlation coefficient of r=-0.4 and a null hypothesis probability of 5%. When we correct the durations for cosmological dilation, the anticorrelation strenghtens, with r=-0.6 and a null hypothesis probability of 0.4%. Considering only those GRBs in our sample that have a well-measured burst peak energy (8 out of 21), we find an anticorrelation between the energy of the burst and the shallow phase duration, with r=-0.80 and a null hypothesis probability of 1.8%. If the burst energy anticorrelation with the shallow phase duration is real, then the dependence of the shallow phase on redshift could be the result of a selection effect, since on average high-redshift bursts with lower energies and longer plateaus would be missed. A burst energy anticorrelation with the shallow phase duration would be expected if the end of the plateau arises from a collimated outflow. Alternative scenarios are briefly discussed involving a possible cosmological evolution of the mechanism responsible for the X-ray shallow decay.

For this reason, several surveys were conducted in 2019 and 2020 to assess its occurrence and to establish an inventory of its potential insect vectors with emphasis on their characterization and importance from 85 sites in 25 provinces across the country. Using a sweeping net, 2604 specimens belonging to the Auchenorrhyncha suborder (Hemiptera) were collected. A total of 213 samples from different crops, including two ornamental species Nerium oleander and Polygala spp., were sampled and tested for the presence of X. fastidiosa by ELISA and PCR techniques during the same period within the same surveyed provinces (plus two additional ones, i.e. 27 provinces). Aphrophoridae species were mainly located in the northern part of Morocco where five potential insect vectors occur, namely Philaenus tesselatus, P. maghresignus, Philaenus sp., Neophilaenus campestris and N. lineatus. Philaenus tesselatus was the most important spittlebug recorded with uneven occurrence throughout the country. Philaenus spumarius has not been found in the present surveys which could indicate that it has been replaced by P. tesselatus. Therefore, the latter should be considered as the main potential insect vector of X. fastidiosa in Morocco. Current status and importance of spittlebugs, sharpshooter-leafhoppers, treehoppers and planthoppers are given. ELISA and PCR results did not show any positive results, which may be seen as good news indicating that X. fastidiosa was not found in Morocco. Regarding occurrence and importance of P. tesselatus in Morocco, pest risk analysis of X. fastidiosa in the country should be revised. Our findings highlight the factors that would contribute to the active spread of the X. fastidiosa once introduced into the country.
Preference for infant-directed speech in infants with hearing aids (Wang et al., 2018)

subject: Medical devices

description: Purpose: It is well established that (a) infants prefer listening to infant-directed speech (IDS) over adult-directed speech (ADS), and (b) IDS facilitates speech, language, and cognitive development, compared with ADS. The main purpose of this study was to determine whether infants with hearing aids (HAs), similar to their peers with normal hearing (NH), show a listening preference for IDS over ADS.Method: A total of 42 infants participated in the study. In Experiment 1, 9 infants with hearing loss, who had approximately 12 months of experience (mean chronological age of 17.57 months) with HAs, and 9 infants with NH, who had similar chronological age (17.54 months), were tested. In Experiment 2, 10 infants with hearing loss, who had approximately 4 months of experience (mean chronological age of 9.86 months) with HAs, and 14 infants with NH, who had similar chronological age (9.09 months), were tested. Infants were tested on their listening preference in 3 randomized blocks: IDS versus silence, ADS versus silence, and IDS versus ADS blocks, using the central fixation preference procedure.Results: Experiment 1 showed that infants with HAs, similar to their peers with NH, listened longer to both IDS and ADS relative to silence; however, neither infants with HAs nor infants with NH showed a listening preference for IDS over ADS. In Experiment 2, both infants with HAs and infants with NH showed a listening preference for IDS and ADS relative to silence; in addition, both groups preferred listening to IDS over ADS.Conclusions: Infants with HAs appear to have sufficient access to the acoustic cues in the speech that allow them to develop an age-equivalent IDS preference. This may be attributed to a combination of being able to use the hearing they do have before receiving HAs and early device fitting. Given previously demonstrated positive associations between IDS preference and language development, this research encourages early interventions focusing on maximizing early auditory experience in infants with hearing loss.

description: Squeezed states and macroscopic superpositions of coherent states have been predicted to be generated dynamically in Bose Josephson junctions. We solve exactly the quantum dynamics of such a junction in the presence of a classical noise coupled to the population-imbalance number operator (phase noise), accounting for, for example, the experimentally relevant fluctuations of the magnetic field. We calculate the correction to the decay of the visibility induced by the noise in the non-Markovian regime. Furthermore, we predict that such a noise induces an anomalous rate of decoherence among the components of the macroscopic superpositions, which is independent of the total number of atoms, leading to potential interferometric applications.

A survey of the problem choices of senior high school students
Creators: name: Williams, David G.
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of the study was twofold: to measure problems and needs of senior high school students as an aid to counsellors and guidance personnel in planning meaningful psychological services in the school, and to compare the problems and needs of students grouped according to school programme in order to determine if there are significant differences between these groups in terms of problems and needs expressed by means of a problem inventory. A population of 574 high school students was selected, comprising the grade eleven classes of two high schools in the area surrounding Vancouver. As each of the schools selected received students from over a wide area, it was assumed that social-economic-ability variables were randomized. The data was presented in a number of forms: 1) according to the intensity of the problem choices as expressed by the intensity scale of the Youth Inventory; 2) according to the percentage of students selecting each problem; 3) by problem areas; 4) by arithmetic means; and 5) by profile charts. This presentation was repeated for: 1) the entire population; 2) the entire male sample according to school programme sub-groups; and 3) the entire female sample according to school programme sub-groups. Analysis of variance was used to determine whether there were significant differences in problem choices between the eight problem areas for the entire population. The analysis of variance disclosed significant differences in five of the eight problem areas: Looking Ahead, About Myself, Getting Along with Others, Health, and Things in General. A Scheffé test for multiple comparisons between means did not disclose any significant differences between the problem choices of the school programme sub-groups. Limitations in sample size in the Visual and Performing Arts, and the Community Services programme sub-groups can be considered a serious weakness of the study. The findings did tend to support the hypothesis, that students with similar sets of problems tend to be found in the same school programmes.

3D Models of Radiatively Driven Colliding Winds In Massive O+O Star Binaries: I. Hydrodynamics

description: The dynamics of the wind-wind collision in massive stellar binaries is investigated using three-dimensional hydrodynamical models which incorporate gravity, the driving of the winds, the orbital motion of the stars, and radiative cooling of the shocked plasma. In this first paper we restrict our study to main-sequence O+O binaries. The nature of the wind-wind collision region is highly dependent on the degree of cooling of the shocked plasma, and the ratio of the flow timescale of the shocked plasma to the orbital timescale. The pre-shock wind speeds are lower in close systems as the winds collide prior to their acceleration to terminal speeds. Radiative inhibition may also reduce the pre-shock wind speeds. Together, these effects can lead to rapid cooling of the post-shock gas. Radiative inhibition is less important in wider systems, where the winds are accelerated to higher speeds before they collide, and the resulting collision region can be largely adiabatic. In systems with eccentric orbits, cold gas formed during periastron passage can persist even at apastron, before being ablated and mixed into its surroundings and/or accelerated out of the system.

description: Microwave probes in on-wafer measurements contribute to a number of parasitic effects deteriorating the accuracy of multiline Thru Reflect Line (mTRL) calibrations. The accuracy of mTRL calibration is especially sensitive in Devices under Test (DUTs) of shorter line length. It has been demonstrated in previous experimental studies that the calibrated results are often only reliable as long as the length of the line is at least 2 mm. However, the reasons behind this phenomenon have not yet been clarified. Therefore, this paper reports on a systematic analysis of the dependency of the mTRL calibration accuracy on probe effects with a focus on coplanar waveguides (CPW) of shorter line length. For the first time, investigations with regard to the probe effects in shorter CPWs are presented.

description: While a lot of investigations have been presented recently explaining the parasitic effects in on-wafer measurements caused by probes, neighborhood and environmental effects, this paper addresses the impact of chuck boundary conditions. Starting from a coplanar waveguide (CPW) measurement example, this paper demonstrates how the most relevant chuck parameters, i.e. thickness and relative permittivity, deteriorate the S-parameters of CPWs.

description: ऐतिहासिक रूप से, चीते पूरे अफ़्रीका और दक्षिण-पश्चिमी एशिया में पाए जाते थे। वे अफ्रीका से लेकर अरब प्रायद्वीप तक, फिर पूर्व में ईरान, अफगानिस्तान और पाकिस्तान से होते हुए भारत तक फैले हुए थे। एशिया में पाए जाने वाले चीतों को एशियाई चीतों के रूप में वर्गीकृत किया गया था। एशियाई चीता को अफ़्रीकी चीते से छोटा माना जाता था, लेकिन उसकी गर्दन अधिक शक्तिशाली और पैर लंबे होते थे। इस कारण से, ऐसी धारणा है कि एशियाई चीते अफ़्रीकी चीतों की तुलना में तेज़ होते हैं, हालाँकि इस दावे का समर्थन करने के लिए कोई वैज्ञानिक प्रमाण नहीं है। अपने मांसल लंबे पैरों, अतिरिक्त ऑक्सीजन सेवन के लिए बड़ी नासिका और ऊंची आंखों के साथ, चीता सबसे तेज़ भूमि स्तनपायी होने का गौरव प्राप्त करता है। वे कम दूरी पर 60 या 70 मील प्रति घंटे की रफ़्तार तक पहुँच सकते हैं, लेकिन उसको कहा पता था की यह विशेषता भारत में उनके विनाश का कारण बनेगी।

description: В статье рассматривается потенциал развития интеграционных процессов в Евразии. Анализируются проблемы и перспективы укрепления взаимоотношений между ЕАЭС и АСЕАН. Отмечается что в результате развития и укрепления сотрудничества ЕАЭС с другими объединениями континента возникает международная полицентрическая институциональная структура, которая, в свою очередь, приведет к росту экономик стран-членов объединений, их заинтересованности в реализации совместных проектов и др. Показано, что АСЕАН является крупнейшим в Юго-Восточной Азии интеграционным объединением. В статье выявляются факторы, которые будут оказывать значительное влияние как на развитие, так и на укрепление отношений между двумя объединениями. Кроме того, помимо положительных аспектов развития двусторонних отношений, авторами также рассматриваются существующие слабые стороны взаимодействия объединений.
