title: Association Between Pelvic Motion and Hand Velocity in College-Aged Baseball Pitchers
Creators: name: Horlbeck, William Temlin
Publisher: name: Utah State University
Year: 2014

description: Previous research suggests that pelvic motion is closely related to pitching performance over the course of a season. Few studies have examined pelvic motion and its relationship to an acute pitching variable. Therefore, the purpose of this study was to investigate the relationship between pelvic motion and hand velocity in college-aged pitchers. Nine healthy club baseball team pitchers performed two tests: A pelvic motion test, and a hand velocity test during a pitch. The pelvic motion test required participants to lift their kicking leg 10 cm off the ground, then hold that position for two seconds before returning to a double leg stance. This procedure was repeated five times. The hand velocity test required participants to perform five maximal-effort pitches thrown from a wind-up position. Motion of the pelvis and hand during the tests was recorded with a passive infrared marker-based motion analysis system (Vicon). Angular displacements (tilts) of the pelvis and peak hand velocity were computed from coordinate data using Nexus software (Vicon). Given the low sample size, ninety-nine percent confidence intervals were used to interpret the correlation (Pearson’s r) between pelvic motion and hand velocity. The intervals were computed using the bootstrap procedure (n=100). Based on ninety-nine percent confidence intervals, we observed a negative correlation between anterior-posterior pelvic tilt and hand velocity (99% CI: -0.45 < r < -0.64) and a positive correlation between medial-lateral pelvic tilt and hand velocity (99% CI: 0.29 < r < 0.53). These data imply that pelvic motion in the sagittal plane is associated with a decrease in hand velocity, while motion in the frontal plane is associated with an increase in hand velocity. Medial-lateral pelvic motion occurs in the same plane as the pitch itself, which could contribute to the overall effectiveness of the kinetic chain in the pitching motion, thus creating a faster pitch.

description: Two recent developments in quantum control, concatenation and optimization of pulse intervals, are combined to yield a strategy to suppress unwanted couplings in quantum systems to high order. Longitudinal relaxation and transverse dephasing can be suppressed so that systems with a small splitting between their energy levels can be kept isolated from their environment. The required number of pulses grows exponentially with the desired order but is only the square root of the number needed if only concatenation is used. An approximate scheme even brings the number down to polynomial growth. The approach is expected to be useful for quantum information and for high-precision nuclear magnetic resonance.

description: The main objective of this thesis is to explore the short and long run causality patterns in the finance – growth nexus and finance-growth-trade nexus before and after the global financial crisis, in the case of Albania. To this end we use quarterly data on real GDP, 13 proxy measures for financial development and the trade openness indicator for the period 1998Q1 – 2013Q2 and 1998Q1-2008Q3. Causality patterns will be explored in a VAR-VECM framework. For this purpose we will proceed as follows: (i) testing for the integration order of the variables; (ii) cointegration analysis and (iii) performing Granger causality tests in a VAR-VECM framework. In the finance-growth nexus, empirical evidence suggests for a positive long run relationship between finance and economic growth, with causality running from financial development to economic growth. The global financial crisis seems to have not affected the causality direction in the finance and growth nexus, thus supporting the finance led growth hypothesis in the long run in the case of Albania. In the finance-growth-trade openness nexus, we found evidence for a positive long run relationship the variables, with causality direction depending on the proxy used for financial development. When the pre-crisis sample is considered, we find evidence for causality running from financial development and trade openness to economic growth. The global financial crisis seems to have affected somewhat the causality direction in the finance-growth-trade nexus, which has become sensible to the proxy used for financial development. On the short run, empirical evidence suggests for a clear unidirectional relationship between finance and growth, with causality mostly running from economic growth to financial development. When we consider the per-crisis sub sample results are mixed, depending on the proxy used for financial development. The same results are confirmed when trade openness is taken into account.

Subjects: SECS-P/02 Politica economica

description: China is a large country characterized by remarkable growth and distinct regional diversity. Spatial disparity has always been a hot issue since China has been struggling to follow a balanced growth path but still confronting with unprecedented pressures and challenges. To better understand the inequality level benchmarking spatial distributions of Chinese provinces and municipalities and estimate dynamic trajectory of sustainable development in China, I constructed the Composite Index of Regional Development (CIRD) with five sub pillars/dimensions involving Macroeconomic Index (MEI), Science and Innovation Index (SCI), Environmental Sustainability Index (ESI), Human Capital Index (HCI) and Public Facilities Index (PFI), endeavoring to cover various fields of regional socioeconomic development. Ranking reports on the five sub dimensions and aggregated CIRD were provided in order to better measure the developmental degrees of 31 or 30 Chinese provinces and municipalities over 13 years from 1998 to 2010 as the time interval of three “Five-year Plans”. Further empirical applications of this CIRD focused on clustering and convergence estimation, attempting to fill up the gap in quantifying the developmental levels of regional comprehensive socioeconomics and estimating the dynamic convergence trajectory of regional sustainable development in a long run. Four clusters were benchmarked geographically-oriented in the map on the basis of cluster analysis, and club-convergence was observed in the Chinese provinces and municipalities based on stochastic kernel density estimation.

description: Near-gate plasmons are a new type of plasma oscillations emerging in homogeneous two-dimensional electron systems where a gate provides partial screening of electron-electron interaction. Here we develop a theory of the near-gate plasmons in van der Waals heterostructures comprising a conducting layer separated by a thin insulator from an uncharged disk-shaped gate. We show that in these structures the near-gate plasmons form gate-size-quantized quasi-stationary discrete modes even in the collisionless limit. Belonging to continuum spectrum of two-dimensional plasmons outside of the disk-gate, the near-gate plasmons are manifested as Fano-like resonances in frequency and magnetodispersions of scattering cross-section of the former scattered off the region under the gate. This enables to recover spectrum of the near-gate plasmons in the van der Waals heterostructures using near-field imaging techniques.

description: The evolution of a many-particle system on a one-dimensional lattice, subjected to a quantum walk can cause spatial entanglement in the lattice position, which can be exploited for quantum information/communication purposes. We demonstrate the evolution of spatial entanglement and its dependence on the quantum coin operation parameters, the number of particles present in the lattice and the number of steps of quantum walk on the system. Thus, spatial entanglement can be controlled and optimized using a many-particle discrete-time quantum walk.

Townhouses in single family areas : an analysis of public attitudes towards increasing density
Creators: name: Battles, Robert Anthony Marvin
Publisher: name: University of British Columbia
Year: 2010

description: The past two decades have seen the construction of an increasing number of multiple dwellings in single family areas. Two possible reasons for permitting development to higher densities are to make more efficient use of land and municipal services, and to allow new residents, especially those with children, to live in a socially stable residential environment. There remains, however, widespread resistance to change within established single family neighbourhoods. Planners are thus often confronted with the problem of achieving increases in density while minimizing feelings of resentment towards incoming residents and a mistrust of government on the part of the existing residents. This study focuses upon homeowners' attitudes towards townhouses constructed in existing single family zones. The primary source of information is personal interviews conducted with a total of 75 single family residents. The interviews were equally divided between three Victoria neighbourhoods: two in which a townhouse project had been built and one in which no change had occurred. This survey followed a literature review which stresses the varying viewpoints from which the response to the introduction of new housing types into a residential neighbourhood has been examined. The purposes of the study were: a) to determine which aspects of townhouse projects are of the greatest concern to surrounding residents, b) to ascertain if and how attitudes are modified by exposure to a totunhouse project and its inhabitants, c) to evaluate the public hearing as a device for measuring community attitudes towards zoning changes, d) to recommend criteria which could guide planners in their evaluation of specific project proposals. Survey results indicated that the most troublesome aspects of town-houses were their effects on views, privacy, and traffic. Another finding was that both negative and positive shifts of attitudes had occurred. Increased concern was generated by the design of the project, while concerns lessened in relation to the issues of privacy, neighbourhood status, the type of people attracted to townhouses, property values, maintenance, parking, and open green spaces. In most cases these shifts were explained by site and project characteristics or by the fact that certain fears had not been realized. The interview results also indicated that the public hearing is an adequate device for measuring the range of residents* concerns. Nevertheless, it was concluded that the attitude survey is a more appropriate tool since it reaches a cross-section of neighbourhood residents. The final chapter describes a set of planning guidelines that should be adopted as the basic criteria for assessing townhouses and the actual project approval process. The need to formulate a municipal rezoning policy based on the above criteria is also discussed.
title: The Intergenerational Income Elasticity in the NLSY97 Dataset
Creators: name: Mueller, Christina
Publisher: name: Utah State University
Year: 2014

description: This paper estimates the intergenerational income elasticity for four differently related groups. The results are IGE’s of 0.1368 between fathers and sons, 0.1734 between fathers and daughters, 0.2076 between mothers and sons and 0.2217 between mothers and daughters. These results are compared to previous studies and found to be significantly lower. Possible explanations are the simple passing of time between studies, the financial recession of 2008, and short-run data availability in the dataset. This study includes many control variables to find explanations of the IGE. The level of schooling is of sole importance and explains up to 49 percent of the IGE for fathers and around 33 percent of the IGE for mothers.

description: The Casimir effect of a piston for massless scalar fields which satisfy Dirichlet boundary conditions in the context of five-dimensional Randall-Sundrum models is studied. In these scenarios we derive and calculate the expression for the Casimir force on the piston. We also discuss the Casimir force in the limit that one outer plate is moved to the remote place to show that the nature of the reduced force between the parallel plates left. In the Randall-Sundrum model involving two branes the two plates attract each other when they locate very close, but the reduced Casimir force turns to be repulsive as the plates separation is not extremely tiny, which is against the experimental phenomena. In the case of one brane model the shape of the reduced Casimir force is similar to that of the standard two-parallel-system in the four-dimensional flat spacetimes while the sign of force remains negative.

Creators: name: Miller, Aimee
Publisher: name: Utah State University
Year: 2014

description: Section 504 of the Rehabilitation Act of 1973 specifically prohibits the discrimination of individuals with disabilities who participate in federally funded programs, including public education. Public education is a major recipient of federal funds and has struggled to apply the law to their practice. As the Office of Civil Rights (the administrator of Section 504) became more rigorous in enforcing this legislation, schools became more frustrated with the vagueness of the requirements and the eligibility standards. To date, schools still lack explicit direction and instruction on how to help students that may qualify for added accommodations, but do not qualify for special education services under the Individuals with Disabilities Education Improvement Act. The purpose of this project was to (1) assess the knowledge and skills of personnel in a large urban junior high school regarding the identification of, and implementation of accommodations for, students with disabilities under Section 504, and (2) develop and evaluate a planning guide and inservice that will assist junior high school personnel in serving students with disabilities through 504 plans. The evaluation results suggest that the training was associated with improvements in teachers' knowledge of the 504 identification and service delivery process as well as improvements in teachers' ratings of their confidence in being able to identify and serve students with disabilities via a 504 plan.

description: In this paper, we present a differential modulation and detection scheme for use in the uplink of a system with a large number of antennas at the base station, each equipped with low-resolution analog-to-digital converters (ADCs). We derive an expression for the maximum likelihood (ML) detector of a differentially encoded phase information symbol received by a base station operating in the low-resolution ADC regime. We also present an equal performing reduced complexity receiver for detecting the phase information. To increase the supported data rate, we also present a maximum likelihood expression to detect differential amplitude phase shift keying symbols with low-resolution ADCs. We note that the derived detectors are unable to detect the amplitude information. To overcome this limitation, we use the Bussgang Theorem and the Central Limit Theorem (CLT) to develop two detectors capable of detecting the amplitude information. We numerically show that while the first amplitude detector requires multiple quantization bits for acceptable performance, similar performance can be achieved using one-bit ADCs by grouping the receive antennas and employing variable quantization levels (VQL) across distinct antenna groups. We validate the performance of the proposed detectors through simulations and show a comparison with corresponding coherent detectors. Finally, we present a complexity analysis of the proposed low-resolution differential detectors

Creators: name: Huish, Marianne Ingram
Publisher: name: Utah State University
Year: 2014

description: Pragmatics, or social/emotional skills are learned early in life by most typically developing children (DeLuzio, Girolametto, 2011). According to the American SpeechLanguage-Hearing Association (ASHA), social/emotional skills involve three major communication strategies. These include 1) using language for different purposes such as greeting, informing, requesting, 2) changing language depending on the relationship with the listener, and 3) following conversational and storytelling rules such as taking turns in conversation, staying on topic, using non-verbal signals, and maintaining appropriate body position and eye contact (ASHA, 2013). Social/emotional skills among children entering into the mainstream kindergarten setting, according to early childhood core state standards, include a development of self-awareness, positive self-esteem, and skills that promote positive interactions with others (Utah State Office of Education, 2013). Success in these social/emotional skills among young children generally contributes to kindergarten readiness.

description: Early detection improves prognosis in pancreatic ductal adenocarcinoma (PDAC) but is challenging as lesions are often small and poorly defined on contrast-enhanced computed tomography scans (CE-CT). Deep learning can facilitate PDAC diagnosis, however current models still fail to identify small (<2cm) lesions. In this study, state-of-the-art deep learning models were used to develop an automatic framework for PDAC detection, focusing on small lesions. Additionally, the impact of integrating surrounding anatomy was investigated. CE-CT scans from a cohort of 119 pathology-proven PDAC patients and a cohort of 123 patients without PDAC were used to train a nnUnet for automatic lesion detection and segmentation (nnUnet_T). Two additional nnUnets were trained to investigate the impact of anatomy integration: (1) segmenting the pancreas and tumor (nnUnet_TP), (2) segmenting the pancreas, tumor, and multiple surrounding anatomical structures (nnUnet_MS). An external, publicly available test set was used to compare the performance of the three networks. The nnUnet_MS achieved the best performance, with an area under the receiver operating characteristic curve of 0.91 for the whole test set and 0.88 for tumors <2cm, showing that state-of-the-art deep learning can detect small PDAC and benefits from anatomy information.

description: We study the deterministic dynamics of single-domain ferromagnetic nanoparticles in a viscous liquid induced by the joint action of the gradient and uniform magnetic fields. It is assumed that the gradient field depends on time harmonically and the uniform field has two components, perpendicular and parallel to the gradient one. We also assume that the anisotropy magnetic field is so strong that the nanoparticle magnetization lies along the anisotropy axis, i.e., the magnetization vector is "frozen" into the particle body. With these assumptions and neglecting inertial effects we derive the torque and force balance equations that describe the rotational and translational motions of particles. We reduce these equations to a set of two coupled equations for the magnetization angle and particle coordinate, solve them numerically in a wide range of the system parameters and analyze the role of the parallel component of the uniform magnetic field. It is shown, in particular, that nanoparticles perform only periodic rotational and translational motions if the perpendicular component of the uniform magnetic field is absent. In contrast, the nanoparticle dynamics in the presence of this component becomes non-periodic, resulting in the drift motion (directed transport) of nanoparticles. By analyzing the short and long-time dependencies of the magnetization angle and particle coordinate we show that the increase in the parallel component of the uniform magnetic field decreases both the particle displacement for a fixed time and its average drift velocity on each period of the gradient magnetic field.

description: O conceito de especismo é um conceito central na análise e avaliação da consideração moral, social, política e legal atribuída a animais não-humanos. O especismo consiste na discriminação daqueles que não pertencem a uma determinada espécie. O termo foi introduzido em 1970 por Richard Ryder (2010) e é similar a outros termos geralmente usados para nomear outras formas de discriminação, tais como os termos racismo e sexismo. Perspectivas especistas são prevalentes nos dias de hoje: animais não-humanos sofrem e morrem actualmente de forma maciça, quer pela acção directa dos seres humanos, quer pela recusa destes em ajudá-los, no que constitui uma demonstração de desprezo pelos interesses destes animais.
Assim, tendo em conta o enquadramento acima, o não-especismo consistirá na ausência de especismo, acarretando, portanto, a consideração equitativa dos interesses dos diferentes indivíduos independentemente da espécie a que pertençam. Por sua vez, o anti-especismo distingue-se do não-especismo na medida em que consiste na oposição ao especismo.

title: Does Motor Learning Generalize Between Distinct Functional Upper Extremity Tasks in Older Adults?
Creators: name: Lindauer, Bergen Elyse
Publisher: name: Utah State University
Year: 2014

description: Background: The process of motor learning can decline with age, such that older adults tend to learn new motor skills at a slower rate and to a lesser degree than younger adults. The degree to which aging affects the generalization of motor learning, however, is unclear.
Objective: The purpose of this study was to test whether task-specific training on one functional motor task would 1) result in motor learning, and 2) generalize to two untrained tasks in older adults.
Methods: Twenty-one adults age 65 years and older participated in this study and were assigned to either a training group or a control group. The training group completed three days of training on a simulated feeding task with their non-dominant hand. The control group received no training. All participants were evaluated at pre-test and at post-test on the feeding task, as well as two other untrained functional upper extremity motor tasks (simulated dressing and writing).
Results: The training group significantly improved feeding task performance from pre-test to post-test, whereas the control group did not. These improvements due to motor learning did not, however, generalize to the two untrained tasks, as neither the training nor control group showed any improvement on the simulated dressing or writing tasks from pre-test to post-test.
Conclusions: These results suggest that, unlike younger adult samples in our previous studies, older adults may not generalize learned information across functionally distinct tasks. Thus, the process of generalization may be particularly susceptible to aging processes.

description: Coding theorems in quantum Shannon theory express the ultimate rates at which a sender can transmit information over a noisy quantum channel. More often than not, the known formulas expressing these transmission rates are intractable, requiring an optimization over an infinite number of uses of the channel. Researchers have rarely found quantum channels with a tractable classical or quantum capacity, but when such a finding occurs, it demonstrates a complete understanding of that channel's capabilities for transmitting classical or quantum information. Here, we show that the three-dimensional capacity region for entanglement-assisted transmission of classical and quantum information is tractable for the Hadamard class of channels. Examples of Hadamard channels include generalized dephasing channels, cloning channels, and the Unruh channel. The generalized dephasing channels and the cloning channels are natural processes that occur in quantum systems through the loss of quantum coherence or stimulated emission, respectively. The Unruh channel is a noisy process that occurs in relativistic quantum information theory as a result of the Unruh effect and bears a strong relationship to the cloning channels. We give exact formulas for the entanglement-assisted classical and quantum communication capacity regions of these channels. The coding strategy for each of these examples is superior to a naive time-sharing strategy, and we introduce a measure to determine this improvement.

description: Although essential in an urban forest, street trees create numerous challenges for municipalities as well as private owners. Lack of species diversity is usually pronounced. In addition, inappropriate species are commonly planted along streets. Selection of street trees should follow established percentage guidelines for tree species, genera, and family in order to maintain diversity when planting in a municipality. Numerous variables such as proximity to buildings or vehicular traffic, soil area, exposure, and road salt usage should also be considered when planting any tree. Planting a diverse urban forest with the right tree in the right place can enhance a city streetscape and reduce the long-term cost of tree replacement and maintenance. Key Words. Street trees, species diversity, location considerations.

description: We prove the local well-posedness of the periodic stochastic Korteweg-de Vries equation with the additive space-time white noise. In order to treat low regularity of the white noise in space, we consider the Cauchy problem in the Besov-type space \hat{b}^s_{p, \infty}(T) for s= -1/2+, p = 2+ such that sp < -1. In establishing the local well-posedness, we use a variant of the Bourgain space adapted to \hat{b}^s_{p, \infty}(T) and establish a nonlinear estimate on the second iteration on the integral formulation. The deterministic part of the nonlinear estimate also yields the local well-posedness of the deterministic KdV in M(T), the space of finite Borel measures on T.

description: Spin correlations in the overdoped region of Bi1.75Pb0.35Sr1.90CuO6+z have been explored with Fe-doped single crystals characterized by neutron scattering, muon-spin-rotation (muSR) spectroscopy, and magnetic susceptibility measurements. Static incommensurate spin correlations induced by the Fe spins are revealed by elastic neutron scattering. The resultant incommensurability delta is unexpectedly large (~0.2 r.l.u.), as compared with delta ~ 1/8 in overdoped superconductor La2-xSrxCuO4. Intriguingly, the large delta in this overdoped region is close to the hole concentration p. This result is reminiscent of the delta ~ p trend observed in underdoped La2-xSrxCuO4; however, it is inconsistent with the saturation of delta in the latter compound in the overdoped regime. While our findings in Fe-doped Bi1.75Pb0.35Sr1.90CuO6+z support the commonality of incommensurate spin correlations in high-Tc cuprate superconductors, they also suggest that the magnetic response might be dominated by a distinct mechanism in the overdoped region.

description: Neural networks in the lazy training regime converge to kernel machines. Can neural networks in the rich feature learning regime learn a kernel machine with a data-dependent kernel? We demonstrate that this can indeed happen due to a phenomenon we term silent alignment, which requires that the tangent kernel of a network evolves in eigenstructure while small and before the loss appreciably decreases, and grows only in overall scale afterwards. We show that such an effect takes place in homogenous neural networks with small initialization and whitened data. We provide an analytical treatment of this effect in the linear network case. In general, we find that the kernel develops a low-rank contribution in the early phase of training, and then evolves in overall scale, yielding a function equivalent to a kernel regression solution with the final network's tangent kernel. The early spectral learning of the kernel depends on the depth. We also demonstrate that non-whitened data can weaken the silent alignment effect.

These are the cyclic group Z_12 and the non-Abelian dicyclic group Dic_3. The quotient manifolds have chi=-6 and Hodge numbers (h^11,h^21)=(1,4). With the standard embedding of the spin connection in the gauge group, Y gives rise to an E_6 gauge theory with 3 chiral generations of particles. The gauge group may be broken further by means of the Hosotani mechanism combined with continuous deformation of the background gauge field. For the non-Abelian quotient we obtain a model with 3 generations with the gauge group broken to that of the standard model. Moreover there is a limit in which the quotients develop 3 conifold points. These singularities may be resolved simultaneously to give another manifold with (h^11,h^21)=(2,2) that lies right at the tip of the distribution of Calabi-Yau manifolds. This strongly suggests that there is a heterotic vacuum for this manifold that derives from the 3 generation model on the quotient of Y. The manifold Y may also be realised as a hypersurface in the toric variety. The symmetry group does not act torically, nevertheless we are able to identify the mirror of the quotient manifold by adapting the construction of Batyrev.

title: Urban Pioneers: A Journey Through the Blurred Lines of Authenticity Within Utah's Folk Music Revival
Creators: name: Haertel, Jennifer J.
Publisher: name: Utah State University
Year: 2014

description: This paper has described the collection of oral histories as part of the Urban Pioneers research project started by folklorist Polly Stewart as a way to document the urban folk music revival in Utah during the 1950s-1960s. Additionally, this paper has detailed how the revival in Utah fit into context within the national movement, especially in terms of the search for authenticity by the majority of revivalists - including a thorough discussion of their own reexamination of experiences that led to an understanding that the authenticity they had been chasing had never existed to begin with.

description: Context: Few exoplanets around hot stars with radiative envelopes have been discovered, although new observations from the TESS mission are improving this. Stars with radiative envelopes have little mixing at their surface, and thus their surface abundances provide a sensitive test case for a variety of processes including potentially star-planet interactions. Atomic diffusion is particularly important in these envelopes, producing chemically peculiar objects such as Am and HgMn stars. Aims: An exoplanet candidate around the B6 star HD 235349 was identified by TESS. Here we determine the nature of this transiting object and identify possible chemical peculiarities in the star. Methods: HD 235349 was observed using the long-slit spectrograph at Tartu Observatory, as well as photometrically by the TESS mission. The spectra were modeled to determine stellar parameters and chemical abundances. The photometric light curve was then analyzed in the context of the stellar parameters to determine properties of the transiting object. Results: We find the transiting object is a low-mass stellar companion, not a planet. However, the primary of this eclipsing binary is a rare type of chemically peculiar star. A strong overabundance of P is found with overabundances of Ne and Nd, and mild overabundances of Ti and Mn, while He is mildly underabundant. There is also clear evidence for vertical stratification of P in the atmosphere of the star. The lack of Hg and weak Mn overabundance suggests that this is not a typical HgMn star. It may be in the class of helium-weak phosphorus-gallium (He-weak PGa) stars, or an intermediate between these two classes. Conclusions: We show that HD 235349 is a rare type of chemically peculiar star (He-weak PGa) in an eclipsing binary system with a low-mass stellar companion. This appears to be the first He-weak PGa star discovered in an eclipsing binary.

description: This study used the CowManager SensOor system to examine the behavioral circadian rhythms of 19 Holstein Friesian and Simmental dairy cows in a semi-open barn over 18 months, from October 1, 2020, to March 31, 2022. Over a cumulative total of 4560 days, the sensor system analyzed high active, active, not active, eating, and rumination behaviors of cows. High active, active, and eating behaviors peaked during daylight hours, while not active and rumination values increased during nighttime periods. Specifically, high active and active behaviors peaked in the morning (09:00-10:00h a.m.), while eating exhibited bimodal peaks in both the morning and evening (10:00h a.m. and 09:00h p.m.). Similarly, rumination values were relatively high in the early morning (05:00h a.m.), declined during the day, and peaked again in the evening (07:00h p.m.). In conclusion, this study reveals that lactating cows’ behavioral patterns, are influenced by circadian rhythms, seasonal changes, and lactation stages.

description: Music classification is a music information retrieval (MIR) task to classify music items to labels such as genre, mood, and instruments. It is also closely related to other concepts such as music similarity and musical preference. In this tutorial, we put our focus on two directions - the recent training schemes beyond supervised learning and the successful application of music classification models. The target audience for this web book is researchers and practitioners who are interested in state-of-the-art music classification research and building real-world applications. We assume the audience is familiar with the basic machine learning concepts. In this book, we present three lectures as follows: 1. Music classification overview: Task definition, applications, existing approaches, datasets, 2. Beyond supervised learning: Semi- and self-supervised learning for music classification, 3. Towards real-world applications: Less-discussed, yet important research issues in practice.

description: The dual-phase xenon time projection chamber (TPC) is one of the most sensitive detector technology for dark matter direct search, where the energy deposition of incoming particle can be converted into photons and electrons through xenon excitation and ionization. The detector response to signal energy deposition varies significantly with the electric field in liquid xenon. We study the detector's light yield and its dependence on the electric field in the PandaX-II dual-phase detector containing 580~kg liquid xenon in the sensitive volume. From our measurements, the light yield at electric fields from 0~V/cm to 317~V/cm is obtained for energy depositions up to 236~keV.

description: Among various plasmonic waveguides, the metal-insulator-metal (MIM) type is the most promising for true subwavelength photonic integration. To date, many photonic devices based on MIM waveguides have been investigated, including resonators. However, most of the reported MIM ring resonators suffer from low extinction ratios. In this paper, we present a comprehensive analysis of the intrinsic reasons for the low performance of MIM ring resonators, and give the analytical transmission relation for a universal all-pass ring resonator which has coupling loss. Based on the analysis we propose the plasmonic racetrack resonators in MIM waveguides and show that the performance can be greatly improved.
