Subjects: subject: Cellular Automata and Lattice Gases (nlin.CG)

description: We consider the problem of computing a response curve for binary cellular automata -- that is, the curve describing the dependence of the density of ones after many iterations of the rule on the initial density of ones. We demonstrate how this problem could be approached using rule 130 as an example. For this rule, preimage sets of finite strings exhibit recognizable patterns, and it is therefore possible to compute both cardinalities of preimages of certain finite strings and probabilities of occurrence of these strings in a configuration obtained by iterating a random initial configuration $n$ times. Response curves can be rigorously calculated in both one- and two-dimensional versions of CA rule 130. We also discuss a special case of totally disordered initial configurations, that is, random configurations where the density of ones and zeros are equal to 1/2.

description: Elections generate incentives for contention and violence. However, collective action problems mute responses to strategic incentives by unorganized individuals, relative to organized groups. Variation in the severity of collective action problems and the degree of strategic behaviour results in distinct patterns of mobilization across these two types of groups that have been overlooked in previous literature. We explore variation in organized and unorganized political mobilization and violence at elections using new event data for over one hundred cities in the developing world from 1960 to 2014. We find that organized groups are more likely to mobilize before elections to influence their outcome, and under permissive opportunity structures at moderate levels of democracy. Mobilization by unorganized individuals occurs at and directly after elections but does not vary by regime type. Distinct mobilization patterns across group type are a major addition to our understanding of the link between elections, democracy, contention and violence.

description: We establish a fundamental relationship between the averaged density of states and the extinction mean free path of wave propagating in random media. From the principle of causality and the Kramers-Kronig relations, we show that both quantities are connected by dispersion relations and are constrained by a frequency sum rule. The results are valid under very general conditions and should be helpful in the analysis of measurements of wave transport through complex systems and in the design of randomly or periodically structured materials with specific transport properties.

description: Empirical evidence points to democratic erosion as dominant pattern in Post-Cold War cases. The debate about democratic erosion so far remains fragmented due to the proliferation of labels, and the lack of conceptualization and a shared definition. This paper presents a concept of democratic erosion as a route of “slow death” of democracy developing three definatory features: agency, opportunity and sequencing. Regarding the drivers of this change, the argument presented here is actor-centered, conceiving democratic erosion as a process shaped by the intentionality and systematic actions of an erosion agent. In view of the mechanism, the article introduces sequencing as specific logic of action that is able to explain the incremental dismantling. This logic of action is derived inductively from the Venezuelan case and illustrates the pattern of active and intentional change of rules realized in sequenced hollowing out of democratic structures, processes, norms, and principles. Five developed sequences serve as framework for the analysis of democratic erosion.
Adam Adamandy Kochański's approximations of π: reconstruction of the algorithm

description: In his 1685 paper "Observationes cyclometricae" published in Acta Eruditorum, Adam Adamandy Kochański presented an approximate ruler-and-compass construction for rectification of the circle. It is not generally known that the first part of this paper included an interesting sequence of rational approximations of π. Kochański gave only a partial explanation of the algorithm used to produce these approximations, while promising to publish details at a later time, which has never happened. We reconstruct the complete algorithm and discuss some of its properties. We also argue that Kochański was very close to discovery of continued fractions and convergents of π.

Effects of inflation on the housing market under rational expectations
Creators: name: Male, SE
Publisher: name: University Of Tasmania
Year: 2023

description: In this study an equilibrium asset-market model of the housing market is developed. The model is used to examine the effects of inflation on the Australian housing market under the maintained hypothesis of rational expectations. It provides a theoretical basis for empirically testing several hypotheses about the effects of inflation, however, the scarcity of relevant and reliable data is an important limitation, and the results are of consequential significance only. Two streams of literature that have emerged from American research in this area are drawn together in the present study and, to that end, the theoretical model presented herein serves as a useful extension and adaptation of previous models. Specifically, attention is directed to the influence of inflation on current housing demand decisions through: the characteristics of the mortgage instrument; the institutional features of the mortgage market; and the user-cost of home ownership. Generation of the testable hypotheses necessiates a brief discourse on the evidence of a 'Fisher effect' in the determination of nominal interest rates in Australia. Some simple experiments are performed in an attempt to provide empirical evidence, consistent with previous cited research, of the absence of such an effect.

Exponential convergence to equilibrium in cellular automata asymptotically emulating identity

Year: 2013
Subjects: subject: Cellular Automata and Lattice Gases (nlin.CG)

description: We consider the problem of finding the density of 1's in a configuration obtained by $n$ iterations of a given cellular automaton (CA) rule, starting from disordered initial condition. While this problems is intractable in full generality for a general CA rule, we argue that for some sufficiently simple classes of rules it is possible to express the density in terms of elementary functions. Rules asymptotically emulating identity are one example of such a class, and density formulae have been previously obtained for several of them. We show how to obtain formulae for density for two further rules in this class, 160 and 168, and postulate likely expression for density for eight other rules. Our results are valid for arbitrary initial density. Finally, we conjecture that the density of 1's for CA rules asymptotically emulating identity always approaches the equilibrium point exponentially fast.

description: The downscaling of optical systems to the micro and nano-scale results in very compliant systems with nanogram-scale masses, which renders them susceptible to optical forces. Here we show a specially designed resonant structure for enabling efficient static control of the optical response with relatively weak repulsive and attractive optical forces. Using attractive gradient optical forces we demonstrate a static mechanical deformation of up to 20 nanometers in the resonator structure. This deformation is enough to shift the optical resonances by roughly 80 optical linewidths.

Teacher stress coping strategies : implications for schools
Creators: name: McKay, KI
Publisher: name: University Of Tasmania
Year: 2023

description: This research examines the interdependence between schools' profiles of education, teacher stress and the coping strategies that teachers use. Education profiles are considered in terms of schools' effectiveness, efficiency, equity, flexibility, quality control, support and vision factors. The stress profile comprises the sources, intensities, and frequencies of stress experienced by teachers. The coping profile is constructed by categorising and determining the success or otherwise of the strategies teachers employ when they encounter difficulties associated with their work. School profiles encompass the education, stress and coping profiles. Comparisons are made between the profiles of nine randomly-selected schools within the Tasmanian Department of Education and the Arts. An analysis of other research into stress and coping in the U.S.A., U.K., Canada, and Australia focuses on the research methodologies used in those studies and the means by which data was obtained. The research design for this study incorporates a between-method verification of data and is based upon the non-directional null hypothesis that there is no interdependence between a school's education, stress, and coping profiles. It is a null hypothesis in that it implies that: ‚Äö the coping strategies employed by teachers do not significantly differ from one school to another, regardless of the schools' stress and education profiles; ‚Äö a school's education profile is independent of the sources, intensities and frequencies of stress experienced by teachers; and ‚Äö the frequency and intensity of stress experienced is not reflected in the coping strategies teachers use. The limitations and assumptions of the current research are also described with acknowledgement of problems that arise in ascertaining the reliability of responses deriving from, and the validity of questions contained within, research instruments. Data have been obtained by means of observations; diaries; individual interviews with school principals, assistant principals, and teachers; group interviews with students; and questionnaires. Both qualitative and quantitative methods of data analysis are used when comparing school profiles and in ascertaining the extent of interdependence between education, stress and coping profiles. It has been ascertained that a school's education profile can be compared with those of other schools, that there is a correlation between stress sources and education profiles and that stress frequencies and intensities differ between schools. It has also been found that, although there is a degree of similarity across schools in the coping strategies employed, there is a significant distinction between the strategy efficacies as adjudged by teachers in the various schools.

Effects of changes in temperature, salinity and undefined properties of sea water on the respiration of Euphausia pacifica Hansen (crustacea) in relation to the species' ecology
Creators: name: Gilfillan, Edward Smith
Publisher: name: University of British Columbia
Year: 2011

description: Temperature, salinity, and other, undefined properties of sea water have been suggested as factors acting to limit the distribution of planktonic organisms through the stresses they impose. The aim of this study was to examine experimentally the effects of changes in these properties on the respiration of Euphausia pacifica Hansen. Both immediate and long term effects of changes in these properties were examined. Assessments of the immediate effects of changes in temperature and salinity on the animals' respiratory rate demonstrated that a sharp reduction in respiratory rate could be used as an indication of stress. The results of these same experiments showed that as the values of temperature and salinity approached the limits of tolerance, the effects of stresses from them interact. The long term effects of changes in temperature and salinity were investigated by determining the limits of these factors that were tolerable to specimens from areas in which the characteristic temperatures and salinities of the water were different. Specimens from the water having the greatest range of values of temperature and salinity (coastal) possessed the greatest tolerance to changes in temperature and salinity; specimens from water having the least range of temperature and salinity (oceanic) had the least tolerance. The tolerances to changes in temperature and salinity observed in these experiments indicated that the distribution of E. pacifica in British Columbia coastal waters was not likely to be influenced by changes in temperature and salinity except near the surface, where the salinity may become low and the temperature high or very low. Experiments taking advantage of the interaction between the effects of temperature and salinity were used to establish that other properties of sea water, while undefined, could impose stress on adult E. pacifica. At the same time a method of assessing the effects of changes in undefined properties between sea waters through a comparison of respiratory rates obtained under standard conditions was developed. The results of experiments in which changes in undefined properties of sea waters collected at two depths in each of two locations were examined indicate that these properties appear to be a function of the origin of the particular water. They also indicate that differences between waters in these properties did not affect the distribution of E. pacifica within either of the two areas investigated, namely the Strait of Georgia and Indian Arm. The results did indicate, however, that populations of E. pacifica were present in each of these areas in which inverse reactions to the same set of undefined properties existed. Presumably these result from persistent differences in undefined properties between the waters resident in each of the two areas.
Brane Gravitational Extension of Dirac's "Extensible Model of the Electron"

description: A gravitational extension of Dirac's "Extensible model of the electron" is presented. The Dirac bubble, treated as a 3-dim electrically charged brane, is dynamically embedded within a 4-dim $Z_{2}$-symmetric Reissner-Nordstrom bulk. Crucial to our analysis is the gravitational extension of Dirac's brane variation prescription; its major effect is to induce a novel geometrically originated contribution to the energy-momentum tensor on the brane. In turn, the effective potential which governs the evolution of the bubble exhibits a global minimum, such that the size of the bubble stays finite (Planck scale) even at the limit where the mass approaches zero. This way, without fine-tuning, one avoids the problem so-called 'classical radius of the electron'.

Testing the influence of small crystals on ice size spectra using Doppler lidar observations

Year: 2009
Subjects: subject: Atmospheric and Oceanic Physics (physics.ao-ph)

description: Measurements of the vertical velocity of ice crystals using a 1.5micron Doppler lidar are described. The statistics from a continuous sample of stratiform ice clouds over 17 months are analysed: the distribution of velocity varies strongly with temperature, with average Doppler velocities of 0.2m/s at -40C increasing to 0.6m/s at -10C presumably due to particle growth and broadening of the size spectrum. We examine the likely influence of small crystals less than 60 microns by forward modelling their effect on the area-weighted fall speed, and comparing the results to the lidar observations. The comparison strongly suggests that the concentration of these small crystals in most ice clouds is much lower than measured in-situ by cloud droplet probes. The discrepancy is attributed to shattering of large crystals on the probe inlet, and we argue that these numerous small particles should not be included in numerical weather and climate model parametrizations.

description: I present a business case for democracy, focusing on the impact of democracy on economic growth. This relationship is widely studied, and results have been less robust for growth than many other development outcomes such as literacy or infant mortality. I discuss four factors pertaining to data quality and modelling choices, suggesting that several previous studies have underestimated the growth-benefits of democracy. I further discuss the relationships between democracy and economic crises and variation in economic performance. By mitigating abysmal economic outcomes and ensuring more stable performance, democracy is generally of benefit to risk-averse entrepreneurs, investors, workers, and consumers alike.

description: We present a numerical study of dephasing of electron spin ensembles in a diffusive quasi-one-dimensional GaAs wire due to the D'yakonov-Perel' spin-dephasing mechanism. For widths of the wire below the spin precession length and for equal strength of Rashba and linear Dresselhaus spin-orbit fields a strong suppression of spin-dephasing is found. This suppression of spin-dephasing shows a strong dependence on the wire orientation with respect to the crystal lattice. The relevance for realistic cases is evaluated by studying how this effect degrades for deviating strength of Rashba and linear Dresselhaus fields, and with the inclusion of the cubic Dresselhaus term.
Stability through constraints: the impact of fiscal rules on autocratic survival

description: A growing literature has investigated the role that formal and informal economic institutions play for autocratic survival. However, this literature has, so far, ignored a type of formal economic institution that has grown in importance among both democracies and non-democracies in recent decades, namely, national fiscal rules. In this article, we argue that fiscal rules can affect autocratic survival but that the effect is time-dependent. The introduction of a stricter fiscal rules framework causes short-term fiscal retrenchment and might increase the uncertainty among regime supporters about the provision of future patronage and spoils. However, stricter fiscal rules also improve long-term fiscal management and, thus, increase investor confidence and economic performance in the long run. Consequently, fiscal rules stabilize autocratic regimes in the long run but not in the short run. Fixed-effect estimations on a panel of autocracies from 1987 to 2016 provide substantial evidence in favour of this argument.

A gonad conditioning study of the greenlip abalone (Haliotis laevigata)
Creators: name: Lleonart, Mark
Publisher: name: University Of Tasmania
Year: 2023

description: The Australian greenlip abalone Haliotis laeviqata is of commercial importance in the abalone diving industry. The species is also believed to have culture potential and accordingly control over reproduction is considered valuable. The major purpose of the study was to accelerate gonad development resulting in spawning outside the natural spawning season. Abalone were collected from Franklin sound in the Furneaux group of islands off the north-east tip of Tasmania. The important features of the conditioning tank were elevated water temperature, the provision of water movement within the tank to distribute feed to sedentary abalone and a diet of preferred red algae. Animals collected on 27 April 1990 were induced to spawn on 21 August 1990, 112 days or 1750 degree days following commencement of gonad conditioning. The natural spawning season of the source population was found to be November to March. A variety of methods for measuring reproductive development of abalone were used. This allowed the utility of individual methods to be examined and comparisons made between methods. Two gonad indices, the gonad bulk index (GBI) and the modified gonad bulk index (MGBI) were used as were a number of assessment methods with a histological component: oocyte size/frequency distribution, mean oocyte diameter, an ovarian phase method and percentage mature spermatozoa. The MGBI was considered more sensitive than the GBI, detecting first significant gonad growth following six weeks of gonad conditioning, compared to nine weeks for the GBI. The gonad indices increased from initial values of 14.1 ¬¨¬± 4.4, n=10 and 0.4 ¬¨¬± 0.2, n=10 for GBI and MGBI respectively to 72.3 ¬¨¬± 9.2, n=10 and 7.0 ¬¨¬± 2.0, n=10 following 105 days of gonad conditioning. Mean oocyte diameter (Am) increased from 30.7 ¬¨¬± 2.0, n=5 initially to 109.7 ¬¨¬± 6.0, n=5 during the same time period. The percentage of male germ cells present as mature spermatozoa increased from zero to 90.6 ¬¨¬± 16.3, n=5 following 24 weeks of conditioning.

description: Inelastic x-ray scattering (IXS) now a widely used technique for studying the dynamics of electrons in condensed matter. We previously posed a solution to the phase problem for IXS [P. Abbamonte, et. al., Phys. Rev. Lett. {\bf 92}, 237401 (2004)], that allows explicit reconstruction of the density propagator of a system. The propagator represents, physically, the response of the system to an idealized, point perturbation, so provides direct, real-time images of electron motion with attosecond time resolution and $Å$-scale spatial resolution. Here we show that the images generated by our procedure, as it was originally posed, are spatial averages over all source locations. Within an idealized, atomic-like model, we show that in most cases a simple relationship to the complete, un-averaged response can still be determined. We illustrate this concept for recent IXS measurements of single crystal graphite.

A television camera to computer interface
Creators: name: Yusuf, Tundey
Publisher: name: University of British Columbia
Year: 2011

description: This is an instrumentation thesis. The interface system discussed is a link between an ordinary TV camera and a computer for storage of visual data. The same system can also be used as a link between the computer and a display monitor. Because of its wide bandwidth, a video signal cannot be sampled at the Nyquist rate and presented to a computer. Previous interface systems overcame the problem by scanning slowly on an element-by-element basis using a special scanner and then presenting the samples to the computer. After processing, the data would be read out at the same slow rate and displayed on a special display monitor. The interface described in this thesis will accept material obtained from an ordinary TV camera scanning at standard rate. By using a "stroboscope" sampling technique the samples are presented to the computer slowly enough for it to process. After processing, the data is displayed in a similar manner on a normally scanned monitor for evaluation. Basically the interface operates as follows: A TV camera video signal is sampled at a rate slow enough for computer acceptance. The camera scans the same picture several hundred times until all the points representing the picture have been sampled and stored, the sampling is controlled such that all the points are each sampled only once. Because of the sampling method consecutive samples in the computer do not correspond to adjacent points on the picture being stored. It may therefore be necessary to programme the computer to arrange the samples such that adjacent data in the computer represent consecutive picture points before processing. After processing, the samples may be rearranged and read out for display in the same order they were stored. The horizontal resolution of the picture being stored can be varied quite easily in steps. For example, a system designed to have a maximum of 480 points/line will also have the ability to provide such lower resolutions as 60, 120 and 240 points/lines. This variation is made possible by the design of the hardware. By software the vertical resolution can be varied between an upper limit of 525 lines per picture and such near submultiples of this as 263 and 131 lines/picture. The thesis is discussed in relation to the PDP-9 computer on which most of the work described was done. However, the system interfaces readily with other computers.
The targum (1939:Jan. 7 - 1939:Jan. 14)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1939

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: The ammonia method to probe variations of the electron-to-proton mass ratio, Delta_mu/mu, is applied for the first time to dense prestellar molecular clouds in the Milky Way. Carefully selected sample of 21 NH_3/CCS pairs observed in the Perseus molecular cloud provide the offset Delta V (CCS-NH_3)= 36+/-7_{stat}+/-13.5_{sys} m/s . A similar offset of Delta V = 40.8 +/- 12.9_{stat} m/s between NH_3 (J,K) = (1,1) and N_2H+ J = 1-0 has been found in an isolated dense core L183 by Pagani et al. (2009). Overall these observations provide a safe bound of a maximum offset between ammonia and the other molecules at the level of Delta V < 100 m/s. This bound corresponds to Delta_mu/mu < 1E-7, which is an order of magnitude more sensitive than available extragalactic constraints. Taken at face value the measured Delta V shows positive shifts between the line centers of NH_3 and these two other molecules and suggest a real offset, which would imply a Delta_mu/mu about 4E-8. If Delta_mu/mu follows the gradient of the local gravitational potential, then the obtained results are in conflict with laboratory atomic clock experiments in the solar system by 5 orders of magnitude, thus requiring a chameleon-type scalar field model. New measurements involving other molecules and a wider range of objects along with verification of molecular rest frequencies are currently planned to confirm these first indications.

An example of computation of the density of ones in probabilistic cellular automata by direct recursion

description: We present a method for computing probability of occurence of 1s in a configuration obtained by iteration of a probabilistic cellular automata (PCA), starting from a random initial configuration. If the PCA is sufficiently simple, one can construct a set of words (or blocks of symbols) which is complete, meaning that probabilities of occurence of words from this set can be expressed as linear combinations of probabilities of occurence of these words at the previous time step. One can then setup and solve a recursion for block probabilities. We demonstrate an example of such PCA, which can be viewed as a simple model of diffusion of information or spread of rumors. Expressions for the density of ones are obtained for this rule using the proposed method.

description: Inflection graphs are highly complex networks representing relationships between inflectional forms of words in human languages. For so-called synthetic languages, such as Latin or Polish, they have particularly interesting structure due to abundance of inflectional forms. We construct the simplest form of inflection graphs, namely a bipartite graph in which one group of vertices corresponds to dictionary headwords and the other group to inflected forms encountered in a given text. We then study projection of this graph on the set of headwords. The projection decomposes into a large number of connected components, to be called word groups. Distribution of sizes of word group exhibits some remarkable properties, resembling cluster distribution in a lattice percolation near the critical point. We propose a simple model which produces graphs of this type, reproducing the desired component distribution and other topological features.

description: Using the general sequential product proposed by Shen and Wu in [J. Phys. A: Math. Theor. 42, 345203, 2009], we derive three criteria for describing non-disturbance between quantum measurements that may be unsharp with such new sequential products, which generalizes Gudder's results.

description: Coronavirus 2019 is a transmissible disease and has caused havoc throughout the world. The present study identifies the novel potential antiviral inhibitors against the nucleocapsid C-terminal domain that aids in RNA-binding and replication. A total of 485,629 compounds were screened, and MD was performed. The trajectory analysis (DCCM & PCA), structural integrity, and degree of compaction depicted the protein-ligand complex stability (PDB-PISA and Rgyr). Results obtained from screening shortlists 13 compounds possessing high Docking score. Further, seven compounds had a permissible RMSD limit (3 Å), with robust RMSF. Post-MD analysis of the top two compounds (204 and 502), DCCM & PCA analysis show a positive atomic displacements correlation among residues of active sites-dimer (Chain A and Chain B) & residual clustering. The ΔGint of RNA-bound (-83.5 kcal/mol) and drug-bound N-CTD-204 (-40.8 kcal/mol) and 502(-39.7 kcal/mol) as compared to Apo (-35.95 kcal/mol) suggests stabilization of protein, with less RNA-binding possibility. The Rgyr values depict the loss of compactness on RNA-binding when compared to the drug-bound N-CTD complex. Further, overlapping the protein complexes (0 ns and 100 ns) display significant changes in RMSD of the protein (204-2.07 Å and 502-1.89 Å) as compared to the Apo (1.72 Å) and RNA-bound form (1.76 Å), suggesting strong interaction for compound 204 as compared to 502. ADMET profiling indicates that these compounds can be used for further experiments (in vitro and pre-clinical). Compound 204 could be a promising candidate for targeting the N-protein-RNA assembly and viral replication. Communicated by Ramaswamy H. Sarma

description: Negotiation is a very common interaction between automated agents. Many common negotiation protocols work with cardinal utilities, even though ordinal preferences, which only rank the outcomes, are easier to elicit from humans. In this work we concentrate on negotiation with ordinal preferences over a finite set of outcomes. We study an intuitive protocol for bilateral negotiation, where the two parties make offers alternately. We analyze the negotiation protocol under different settings. First, we assume that each party has full information about the other party's preference order. We provide elegant strategies that specify a sub-game perfect equilibrium for the agents. We further show how the studied negotiation protocol almost completely implements a known bargaining rule. Finally, we analyze the no information setting. We study several solution concepts that are distribution-free, and analyze both the case where neither party knows the preference order of the other party, and the case where only one party is uninformed.
title: The Effects of Lifting With Intent on Hip and Knee Moments During Back Squats

description: Back squatting is a widely used movement in the strength and conditioning community. Within the last few years, velocity-dependent training and its application of tracking intensity have increased in popularity. Biomechanics research has frequently examined force generation, joint loading, and muscle contributions of back squats with different bar placement, stance width, and increasing barbell loads. However, no information exists regarding whether lifting with intent increases velocity and how increased velocity is biomechanically achieved. This study aimed to examine how lifting with intent affects bar velocity and how joint moment alterations could contribute to these potential changes in velocity. Fifteen males with ≥1 year resistance training and ≥1 day of lower body training per week participated. Squat stance, bar placement, and footwear were standardized. Participants completed 3 self-selected velocity squats with a pause at the bottom at 70% and 80% then 1 repetition at 90% and 1RM. Participants then performed back squats with the same 70% and 80% 1RM load, but with the instruction to ascend “as fast as possible” along with visual feedback via a tendo unit. Paired samples t-tests were used to examine differences in average ascent velocity and peak hip and knee moments. Ascent velocity was significantly increased during instructed velocity compared to self-selected for both 70% and 80% (p<.01) 1RM. Peak hip moments were significantly increased with instructed velocity at 70% (p=.024) and 80% (p<0.01) 1RM. However, peak knee moments were not different between self-selected velocity and instructed velocity for neither the 70% nor 80% conditions. This study illustrates that 1) lifting with intent can increase ascent velocity and 2) increases in velocity are achieved via increased hip moments. Thus, training with the same load but higher velocities can enhance hip loading/strengthening. Considering the hip is the limiting factor in maximal squatting, increasing strength at the hip via velocity squats could be a beneficial alternative to maximal load squats.
