description: We study high energy charged particle collisions near the horizon in an electromagnetic field around a rotating black hole and reveal the condition of the fine-tuning to obtain arbitrarily large center-of-mass (CM) energy. We demonstrate that the CM energy can be arbitrarily large as the uniformly magnetized rotating black hole arbitrarily approaches maximal rotation under the situation that a charged particle plunges from the innermost stable circular orbit (ISCO) and collides with another particle near the horizon. Recently, Frolov [Phys. Rev. D 85, 024020 (2012)] proposed that the CM energy can be arbitrarily high if the magnetic field is arbitrarily strong, when a particle collides with a charged particle orbiting the ISCO with finite energy near the horizon of a uniformly magnetized Schwarzschild black hole. We show that the charged particle orbiting the ISCO around a spinning black hole needs arbitrarily high energy in the strong field limit. This suggests that Frolov's process is unstable against the black hole spin. Nevertheless, we see that magnetic fields may substantially promote the capability of rotating black holes as particle accelerators in astrophysical situations.

description: We report on magnetic susceptibility and specific heat measurements of the cubic helimagnet FeGe in external magnetic fields and temperatures near the onset of long-range magnetic order at T_C=278.2(3)K. Pronounced anomalies in the field-dependent chi_ac(H) data as well as in the corresponding imaginary part chi"_ac(H) reveal a precursor region around T_C in the magnetic phase diagram. The occurrence of a maximum at T_0=279.6K in the zero-field specific heat data indicates a second order transition into a magnetically ordered state. A shoulder evolves above this maximum as a magnetic field is applied. The field dependence of both features coincides with crossover lines from the field-polarized to the paramagnetic state deduced from chi_ac(T) at constant magnetic fields. The experimental findings are analyzed within the standard Dzyaloshinskii theory for cubic helimagnets. The remarkable multiplicity of modulated precursor states and the complexity of the magnetic phase diagram near the magnetic ordering are explained by the change of the character of solitonic inter-core interactions and the onset of specific confined chiral modulations in this area.

description: During and after World War I, Unna’s polychrome methylene blue, a supravital stain critical to the Mayo Clinic’s frozen section technique, became unavailable. Benjamin Taylor Terry (1876-1955) developed a replacement stain, and an intraoperative diagnostic method (rapid razor sections) that was arguably better, faster, and inexpensive compared with frozen sections. However, Terry’s contributions to the history of surgical pathology are largely unknown. But his efforts helped solidify the role of hospital-based pathology practice in North America. He played critical roles in stain development, popularization of intraoperative diagnostic techniques, and the institutionalization of hospital-based pathology. After thoroughly studying Terry’s life and the evolution of his methodology, his method was revived and adapted to a contemporary environment. Using a new sectioning device and modifications to his methodology, tissue sections were produced, stained, examined microscopically, and critiqued. Further research in perfecting diagnostic-worthy sections could provide a benefit to pathology laboratories in resource-limited countries.

description: As quantum key distribution becomes a mature technology, it appears clearly that some assumptions made in the security proofs cannot be justified in practical implementations. This might open the door to possible side-channel attacks. We examine several discrepancies between theoretical models and experimental setups in the case of continuous-variable quantum key distribution. We study in particular the impact of an imperfect modulation on the security of Gaussian protocols and show that approximating the theoretical Gaussian modulation with a discrete one is sufficient in practice. We also address the issue of properly calibrating the detection setup, and in particular the value of the shot noise. Finally, we consider the influence of phase noise in the preparation stage of the protocol and argue that taking this noise into account can improve the secret key rate because this source of noise is not controlled by the eavesdropper.

The business of censorship : content management and the Chinese economy
Creators: name: Clark, Joshua
Publisher: name: University of British Columbia
Year: 2010

description: Content control and censorship on the Internet are increasingly important topics for scholars of democratization, media and communications. Most studies have examined the relationship between the Internet, content management and various elements important to democratization such as the formation of civil society organizations. This thesis attempts to expand this discussion by examining the effects of online content management on economic systems, using the People's Republic of China as an example. China features a globally integrated economy that is increasing dependent on manufacturing and services while simultaneously maintaining one of the most extensive online content management systems in the world. This paper attempts to show how the Communist Party of China is able to reconcile the need for connectivity in order to drive their economy while maintaining political control. It also discusses the long-term implications of this strategy. The first section consists of a series of quantitative and qualitative tests to determine how various classes of websites are managed. These tests reveal that in order to maintain the flow of information necessary for a globally integrated economy, the Chinese Communist Party utilizes strategies that manage but not block the information flows related to business. This survey is followed by a case study examining the relationship between Google and China, and the implications of Chinese regulation and control for the broader economy. The results indicate that the Chinese regulatory strategy, which is designed to meet political goals, is creating a divergent technology industry that caters to the party's needs. This development may have serious implications for the future of the Chinese globalization effort as it poses a threat to interoperability and exchange between Chinese online presences and those in the rest of the world.

description: The recent advancements in auto-regressive multimodal large language models (MLLMs) have demonstrated promising progress for vision-language tasks. While there exists a variety of studies investigating the processing of linguistic information within large language models, little is currently known about the inner working mechanism of MLLMs and how linguistic and visual information interact within these models. In this study, we aim to fill this gap by examining the information flow between different modalities -- language and vision -- in MLLMs, focusing on visual question answering. Specifically, given an image-question pair as input, we investigate where in the model and how the visual and linguistic information are combined to generate the final prediction. Conducting experiments with a series of models from the LLaVA series, we find that there are two distinct stages in the process of integration of the two modalities. In the lower layers, the model first transfers the more general visual features of the whole image into the representations of (linguistic) question tokens. In the middle layers, it once again transfers visual information about specific objects relevant to the question to the respective token positions of the question. Finally, in the higher layers, the resulting multimodal representation is propagated to the last position of the input sequence for the final prediction. Overall, our findings provide a new and comprehensive perspective on the spatial and functional aspects of image and language processing in the MLLMs, thereby facilitating future research into multimodal information localization and editing. Our code and collected dataset are released here: https://github.com/FightingFighting/cross-modal-information-flow-in-MLLM.git.

description: Abstract

Women in leadership can be understood as an embodiment of Agape in leadership. This article delves into the dynamic landscape of women in leadership roles, interpreting their influence through the prism of Agape - a concept rooted in selfless love and compassion. By scrutinizing the transformative impact of women leaders across diverse sectors, the narrative accentuates their distinct qualities, such as compassion, empathy, and selflessness, which resonate with the foundational tenets of Agape. The intersection of women in leadership and agape principles is  evident in corporate settings, where companies led by women demonstrate higher levels of employee satisfaction and innovation. The political arena also witnesses the influence of women leaders advocating for social justice and inclusivity. In education, women in leadership roles champion holistic approaches, nurturing not only academic excellence but also emotional intelligence. The article emphasizes the positive organizational transformations resulting from the infusion of agape into leadership, fostering sustainable and effective governance. Despite historical challenges, the 21st century has seen a paradigm shift, acknowledging and leveraging the value of diverse perspectives women bring to leadership. The article underscores the importance of challenging gender stereotypes, promoting diversity, and recognizing the business case for gender inclusivity. The manifestation of agape in women’s leadership extends beyond organizational boundaries, contributing to societal progress, ethical business practices, and global cooperation. The amalgamation of women in leadership and agape principles represents a profound shift in leadership paradigms, emphasizing compassion, empathy, selflessness, and a commitment to the greater good.

description: We provide dramatic evidence that `Mellin space' is the natural home for correlation functions in CFTs with weakly coupled bulk duals. In Mellin space, CFT correlators have poles corresponding to an OPE decomposition into `left' and `right' sub-correlators, in direct analogy with the factorization channels of scattering amplitudes. In the regime where these correlators can be computed by tree level Witten diagrams in AdS, we derive an explicit formula for the residues of Mellin amplitudes at the corresponding factorization poles, and we use the conformal Casimir to show that these amplitudes obey algebraic finite difference equations. By analyzing the recursive structure of our factorization formula we obtain simple diagrammatic rules for the construction of Mellin amplitudes corresponding to tree-level Witten diagrams in any bulk scalar theory. We prove the diagrammatic rules using our finite difference equations. Finally, we show that our factorization formula and our diagrammatic rules morph into the flat space S-Matrix of the bulk theory, reproducing the usual Feynman rules, when we take the flat space limit of AdS/CFT. Throughout we emphasize a deep analogy with the properties of flat space scattering amplitudes in momentum space, which suggests that the Mellin amplitude may provide a holographic definition of the flat space S-Matrix.

description: The Hubble radius is a particular manifestation of the Universe's gravitational horizon, R_h(t_0)=c/H_0, the distance beyond which physical processes remain unobservable to us at the present epoch. Based on recent observations of the cosmic microwave background (CMB) with WMAP, and ground-based and HST searches for Type Ia supernovae, we now know that R_h(t_0)~13.5 Glyr. This coincides with the maximum distance (ct_0~13.7 Glyr) light could have traveled since the big bang. However, the physical meaning of R_h is still not universally understood or accepted, though the minimalist view holds that it is merely the proper distance at which the rate of cosmic recession reaches the speed of light c. Even so, it is sometimes argued that we can see light from sources beyond R_h, the claim being that R_h lies at a redshift of only ~2, whereas the CMB was produced at a much greater redshift (~1100). In this paper, we build on recent developments with the gravitational radius by actually calculating null geodesics for a broad range of FRW cosmologies, to show---at least in the specific cases we consider here, including LCDM---that no photon trajectories reaching us today could have ever crossed R_h(t_0). We therefore confirm that the current Hubble radius, contrary to a commonly held misconception, is indeed the limit to our observability. We find that the size of the visible universe in LCDM, measured as a proper distance, is approximately 0.45ct_0.

description: We perform a helicity decomposition in the full Lagrangian of the class of Massive Gravity theories previously proven to be free of the sixth (ghost) degree of freedom via a Hamiltonian analysis. We demonstrate, both with and without the use of nonlinear field redefinitions, that the scale at which the first interactions of the helicity-zero mode come in is $Λ_3=(M_Pl m^2)^{1/3}$, and that this is the same scale at which helicity-zero perturbation theory breaks down. We show that the number of propagating helicity modes remains five in the full nonlinear theory with sources. We clarify recent misconceptions in the literature advocating the existence of either a ghost or a breakdown of perturbation theory at the significantly lower energy scales, $Λ_5=(M_Pl m^4)^{1/5}$ or $Λ_4=(M_Pl m^3)^{1/4}$, which arose because relevant terms in those calculations were overlooked. As an interesting byproduct of our analysis, we show that it is possible to derive the Stueckelberg formalism from the helicity decomposition, without ever invoking diffeomorphism invariance, just from a simple requirement that the kinetic terms of the helicity-two, -one and -zero modes are diagonalized.

description: Effective nurse-physician collaboration is an essential component of providing safe patient care. Nurse managers are in a unique position to witness, experience, and lead collaborative practice. The purpose of this study is to gain a better understanding of the social process of nurse-physician collaboration through the lens of nurse managers, as well as how the system supports or impedes collaboration. Seven nurse managers from surgical inpatient units from three major hospitals in western Canada were interviewed following the constructivist grounded theory methodology. Findings revealed five categories in the process of nurse-physician collaboration: (1) communicating expectations and accountability, (2) creating intentional interactions, (3) building trust and earning respect, (4) building relationships, and (5) enculturating collaboration. Nurse-physician collaboration is a multi-faceted, on-going process with the relationship at the centre. Gaining an understanding of the process of nurse-physician collaboration will facilitate improvements to collaborative practice and the delivery of safe health care.

description: Saturable absorbers are a key component for mode-locking femtosecond lasers. Polymer films containing graphene flakes have recently been used in transmission as laser mode-lockers, but suffer from high nonsaturable loss, limiting their application in low-gain lasers. Here we present a saturable absorber mirror based on a film of pure graphene flakes. The device is used to mode lock an erbium-doped fiber laser, generating pulses with state-of-the-art, sub-200-fs duration. The laser characteristic indicate that the film exhibits low nonsaturable loss (13% per pass) and large absorption modulation depth (45% of low-power absorption).

description: We report synchrotron x-ray powder diffraction measurements of Ce0.8La0.1Th0.1 subject to pulsed magnetic fields as high as 28 Tesla. This alloy is known to exhibit a continuous volume collapse on cooling at ambient pressure, which is a modification of the gamma -> alpha transition in elemental cerium. Recently, it has been suggested on the basis of field-cooled resistivity and pulsed field magnetization measurements that the volume collapse in this alloy can be suppressed by the application of magnetic fields. Conversely, our direct diffraction measurements show a robust collapsed phase, which persists in magnetic fields as high as 28 Tesla. We also observe nanoscale disorder in the collapsed phase, which increasingly contaminates the high temperature phase on thermal cycling.

Evaluation of primary wood processing residues for bioenergy in British Columbia
Creators: name: Kehbila, Atenkeng Taku
Publisher: name: University of British Columbia
Year: 2011

description: The growing energy demand in the world emphasizes the need for a more reliable energy source. To this end, a "fundamental” re-think is critical for an effective sustainable bioenergy production in the 21st century. BC has traditionally been the largest lumber and residue producing province in Canada, thus advancing bioenergy production in BC holds the potential to utilize residues from primary wood processing mills. The main objectives of this study were: (1) to develop a database using important physical characteristics of residues from sawmills, and plywood mills in BC. (2) to estimate the total production, utilization and surpluses of primary residues within each forest region; and (3) to create a Dijkstra logarithm model partnered with a vector-based geographical information system (GIS) to investigate the optimal location of bio-based industrial plants using the available residues from BC’s mills. Laboratory analysis of primary mill residues indicated that the higher heating values (HHV) ranged from 17 – 21.5 MJ/kg with a mean of 18.9MJ/kg. Ash contents were quite small for whitewood (0 – 2%) and higher for bark and hogfuel (2 – 6.5%) with a mean of 1.6%. The moisture content (MC) on wet mass basis ranged from 5 – 317% with a mean of 105%. The basic density ranged from 120 – 1151 kg/m³ with a mean of 352 kg/m³. The average particle size (Dp₅₀) of the residues ranged from 0.2 – 49.7 mm. Analyses of the availability of primary mill residues revealed that due to the demands of the pulp and paper industry, there were no available residues in BC for bioenergy production in 2006. Consequently, an artificial situation was created in order to demonstrate the potential benefits of the GIS-Dijkstra integrated modeling framework to determine the most preferred locations for bioenergy plants. Under this hypothetical scenario surplus residue generated in the Southern forest region had the lowest residue cost for bark at $15/BDt followed the coastal forest region at $46/BDt and the Northern forest region at $51/BDt. While the Southern interior forest region still had the cheapest whitewood residue cost at $31/BDt followed the Northern forest region at $78/BDt and the coastal forest region at $84/BDt.

description: In recent years, the prominence of immoral, law-breaking antihero characters (Machiavellian or Mach-antiheroes) has increased in popular media. How can this trend be explained? It may be the case that, due to globalized exposure to real life injustice, some people experience an increase in anomie and thus prefer characters who can more realistically solve injustice. In two experiments, one correlational and one comparing groups exposed to antiheroes that varied in personal and global justification, this hypothesis was examined. Although evidence was not found to directly support the hypothesis, elements of just world beliefs, anomie, and personal morality were found to be related to Mach-antihero appeal. Results also support the idea that audiences do engage in moral evaluations of Mach-antiheroes. A full discussion of results, as well as implications, limitations, and future directions for research, appear as a conclusion. Key words: antihero, justice, belief in a just world, anomie, morality

description: Adolescence is a critical time in human life with regards to identity development; adolescents may experience increased emotional turmoil, stress, and susceptibility to mental health problems (O’Connell, Boat, & Warner, 2009). Implementing a mindfulness program within school curriculum may positively influence this crucial time of growth. This case study focused on teaching self-compassion to adolescents through the “Learning to BREATHE” program. Self-compassion involves being kind towards oneself, understanding that we are all part of common humanity, and mindfulness (Neff, 2003a). This multi-methods study was grounded in Integral Theory (Wilber, 2007), which integrates multiple perspectives of self-compassion. In keeping with Integral Methodological Pluralism, self-compassion was examined through multiple lenses with both qualitative and quantitative methodologies. The findings indicated that a mindfulness program teaching self-compassion had many benefits to students, including increased mindful awareness and focused attention; emotional awareness and regulation; self-awareness, self-kindness, and self-acceptance; resiliency and growth mindset; compassion, acceptance, and forgiveness for others; and a belief it could reduce bullying in schools. While school administrators believed that social and emotional learning can benefit students, classroom application and staff buy-in remains a challenge. Mindfulness programs in the school context will need to be introduced slowly over the next several years as students, parents, teachers, and administrators all have to understand the importance of these skills, before they can be implemented into the classroom.

description: We present Herschel PACS photometry of seventeen B- to M-type stars in the 30 Myr-old Tucana-Horologium Association. This work is part of the Herschel Open Time Key Programme "Gas in Protoplanetary Systems" (GASPS). Six of the seventeen targets were found to have infrared excesses significantly greater than the expected stellar IR fluxes, including a previously unknown disk around HD30051. These six debris disks were fitted with single-temperature blackbody models to estimate the temperatures and abundances of the dust in the systems. For the five stars that show excess emission in the Herschel PACS photometry and also have Spitzer IRS spectra, we fit the data with models of optically thin debris disks with realistic grain properties in order to better estimate the disk parameters. The model is determined by a set of six parameters: surface density index, grain size distribution index, minimum and maximum grain sizes, and the inner and outer radii of the disk. The best fitting parameters give us constraints on the geometry of the dust in these systems, as well as lower limits to the total dust masses. The HD105 disk was further constrained by fitting marginally resolved PACS 70 micron imaging.

description: Gaia Bp/Rp spectra for over two hundred million stars have great potential for mapping metallicity across the Milky Way. We aim to construct an alternative catalog of atmospheric parameters from Gaia Bp/Rp spectra by fitting them with synthetic spectra based on model atmospheres, and provide corrections to the Bp/Rp fluxes according to stellar colors, magnitudes, and extinction. We use GaiaXPy to obtain calibrated spectra and apply FERRE to match the corrected Bp/Rp spectra with models and infer atmospheric parameters. We train a neural network using stars in APOGEE to predict flux corrections as a function of wavelength for each target. Based on the comparison with APOGEE parameters, we conclude that our estimated parameters have systematic errors and uncertainties in $T_{\mathrm{eff}}$, $\log g$, and [M/H] about $-38 \pm 167$ K, $0.05 \pm 0.40$ dex, and $-0.12 \pm 0.19$ dex, respectively, for stars in the range $4000 \le T_{\mathrm{eff}} \le 7000$ K. The corrected Bp/Rp spectra show better agreement with both models and Hubble Space Telescope CALSPEC data. Our correction increases the precision of the relative spectrophotometry of the Bp/Rp data from $3.2\% - 3.7\%$ to $1.2\% - 2.4\%$. Finally, we have built a catalog of atmospheric parameters for stars within $4000 \le T_{\mathrm{eff}} \le 7000$ K, comprising $68,394,431$ sources, along with a subset of $124,188$ stars with $\mathrm{[M/H]} \le -2.5$. Our results confirm that the Gaia Bp/Rp flux calibrated spectra show systematic patterns as a function of wavelength that are tightly related to colors, magnitudes, and extinction. Our optimization algorithm can give us accurate atmospheric parameters of stars with a clear and direct link to models of stellar atmospheres, and can be used to efficiently search for extremely metal-poor stars.

description: Random tensor models for a generic complex tensor generalize matrix models in arbitrary dimensions and yield a theory of random geometries. They support a 1/N expansion dominated by graphs of spherical topology. Their Schwinger Dyson equations, generalizing the loop equations of matrix models, translate into constraints satisfied by the partition function. The constraints have been shown, in the large N limit, to close a Lie algebra indexed by colored rooted D-ary trees yielding a first generalization of the Virasoro algebra in arbitrary dimensions. In this paper we complete the Schwinger Dyson equations and the associated algebra at all orders in 1/N. The full algebra of constraints is indexed by D-colored graphs, and the leading order D-ary tree algebra is a Lie subalgebra of the full constraints algebra.

description: Local peoples’ attitudes towards protected areas are based on local values, perceptions and experiences with management. The relationships of residents of La Tigra National Park (LTNP) to the forest, park and park management and key issues are identified and recommendations on integrating conservation and livelihood into park management are presented. Although formal conservation knowledge was relatively low, local forest and livelihood values were evident. Key issues were use of resources, land rights and livelihood restriction as well as lack of economic benefits and lack of participation in management activities. In order to better integrate conservation and livelihood needs management should increase participation, create a compensation system, facilitate a local system for resource extraction permitting, develop a community tree planting program, and increasing transparency and communication between communities and management bodies. Incorporating local values and perceptions into park management may lead to more sustainable communities and more viable protected areas.
Polariton states bound to defects in GaAs/AlAs planar microcavities

description: We report on polariton states bound to defects in planar GaAs/AlAs microcavities grown by molecular beam epitaxy. The defect types relevant for the spatial polariton dynamics in these structures are cross-hatch misfit dislocations, and point-like defects extended over several micrometers. We attribute the latter defects to Ga droplets emitted occasionally by the Ga cell during the growth. These defects, also known as oval defects, result in a dome-like local modulation of surface, which is translated into the cavity structure and leads to a lateral modulation of the cavity polariton energy of up to 15\,meV. The resulting spatially localized potential landscape for the in-plane polariton motion creates a series of bound states. These states were characterized by spectrally resolved transmission imaging in real and reciprocal space, and reveal the spatial potential created by the defects. Interestingly, the defect states exhibit long lifetimes in the 10ps range, which we attribute to a spatially smooth confinement potential.

Capsule endoscopy versus standard of care in obscure gastrointestinal bleeding: A randomized controlled trial
Creators: name: Adams, Fatin
Publisher: name: Graduate Studies

Subjects: subject: Epidemiology
subject: Iron deficiency anemia
subject: obscure occult gastrointestinal bleeding
subject: capsule endoscopy

description: Iron deficiency anemia (IDA) is a common problem worldwide. The initial workup usually involves performing a bidirectional endoscopy. When negative, the small bowel could be the source of obscure gastrointestinal bleeding presenting as IDA. The next best diagnostic test is uncertain. Wireless capsule endoscopy (WCE) is a non-invasive new technology that allows examination of the entire small bowel. Methods: We designed a randomized controlled pilot study to outline the challenges for conducting a full randomized controlled trial (RCT) to determine if WCE should be first-line investigation in such cases. 109 patients were enrolled; 55 intervention (WCE) & 54 controls (standard of care) (SC). Results: Two-years post-randomization there was no difference in anemia between the two groups. Conclusion: Few methodological hurdles for conducting a full RCT were identified.
NACS: non-overlapping AP's caching scheme to reduce handoff in 802.11 wireless LAN

description: With the escalation of the IEEE 802.11 based wireless networks, voice over IP and analogous applications are also used over wireless networks. Recently, the wireless LAN systems are spaciously deployed for public Internet services. In public wireless LAN systems, reliable user authentication and mobility support are indispensable issues. When a mobile device budges out the range of one access point (AP) and endeavor to connect to new AP, it performs handoff. Contemporarily, PNC and SNC were proposed to propagate the MN context to the entire neighboring AP's on the wireless network with the help of neighbor graph. In this paper, we proposed a non-overlapping AP's caching scheme (NACS), which propagates the mobile node context to those AP's which do not overlap with the current AP. To capture the topology of non-overlapping AP's in the wireless network, non-overlapping graph (NOG) is generated at each AP. Simulation results shows that NACS reduces the signaling cost of propagating the MN context to the neighbor AP's in the wireless network.

description: A characterization study was carried out to determine the moisture content, proximate and ultimate compositions, heating value, and thermal weight loss behavior of fourteen different municipal solid wastes (MSW). An empirical model was developed for the high heating value (HHV) estimation of MSW: HHV (MJ/kg) = 0.350 C + 1.01 H - 0.0826 O, which is expressed in terms of weight percentages on a dry basis of carbon (C), hydrogen (H) and oxygen (O). The validation results suggest that this model was effective in producing accurate outputs that were close to the experimental values. A series of experiments pyrolysing coffee cups were also performed using zeolite type catalysts. In the presence of Ga/HZSM-5 in the mixed bed reaction, the pyrolysis oil’s effective hydrogen-to-carbon molar ratio (H/Ceff) was markedly increased, from 0.49 to 1.11. Valuable phenolic compounds were observed to be the main species in the pyrolysis oil.
The poetics of Persian music : the intimate correlation between prosody and Persian classical music
Creators: name: Amoozegar-Fassie, Farzad
Publisher: name: University of British Columbia
Year: 2010

description: Throughout most historical narratives and descriptions of Persian arts, poetry has had a profound influence on the development and preservation of Persian classical music, in particularly after the emergence of Islam in Iran. A Persian poetic structure consists of two parts: the form (its fundamental rhythmic structure, or prosody) and the content (the message that a poem conveys to its audience, or theme). As the practice of using rhythmic cycles—once prominent in Iran— deteriorated, prosody took its place as the source of rhythmic organization and inspiration. The recognition and reliance on poetry was especially evident amongst Iranian musicians, who by the time of Islamic rule had been banished from the public sphere due to the sinful socio-religious outlook placed on music. As the musicians’ dependency on prosody steadily grew stronger, poetry became the preserver, and, to a great extent, the foundation of Persian music’s oral tradition. While poetry has always been a significant part of any performance of Iranian classical music, little attention has been paid to the vitality of Persian/Arabic prosody as its main rhythmic basis. Poetic prosody is the rhythmic foundation of the Persian repertoire the radif, and as such it makes possible the development, memorization, expansion, and creation of the complex rhythmic and melodic compositions during the art of improvisation.
