description: PURPOSE: At rest and during a tactical pistol competition classifier, heart rate variability (HRV) time-domain, high frequency (HF), low frequency (LF), total power (TP), and inter-beat-interval (IBI) measurements were examined in 28, healthy subjects (37 ± 11 yr old, 180 ± 7 cm, 90.6 ± 16.9 kg) for correlations to performance. METHODS: Resting measurements were taken supine in a quiet, dimmed room, during metronomic breathing. The shooting task consisted of three stages, comprised of several strings each. The strings were initiated by a starting buzzer and involved several tactical maneuvers, including holster draws, engaging multiple targets, firing on the move, from behind cover, and single handed. Time to completion and accuracy were recorded, and combined to form a calculated score with lower values indicating better shooting performance. HRV measures recorded during shooting were subtracted from those recorded at rest to determine delta (∆) scores. Each subject completed a questionnaire on competition and training history. The years spent competing, frequency of competition, number of classifiers completed, and whether they had received professional training were coded and analyze for relationships to HRV and shooting performance measures. RESULTS: Raw time was significantly correlated to shooting IBI (r = 0.404), ∆IBI (r = -0.426), ∆HF (r = 0.468), ∆TP (r = 0.392), years competing (r = -0.422), frequency of competition (r = -0.511), and number of classifiers (r = -0.554). Inaccuracy was significantly correlated to ∆TP (r = 0.416) and the ∆LF (r = 0.376). Calculated match score was significantly correlated to ∆IBI (r = -0.458), ∆HF (r = 0.467), 6LF (r= 0.377), 6TP (r = 0.451), frequency of competition (r = -0.465), number of classifiers (r = -0.515), and lack of professional training (r = 0.448). Training excluded, a step-wise linear regression found 34.6% of the adjusted variance in score (Adjusted R2 = 0.346, 2,25F = 8.129, p < 0.01) was determined by the ∆IBI (standardized β = -0.582, p = 0.001) and 6HF (standardized β = 0.447, p = 0.011). CONCLUSION: These results suggest that ∆IBI arises from the physical work of accomplishing the task at a faster rate, and is independent of the psychological stress response as measured by HRV. Superior performing shooters attenuated the reduction in HRV, regardless of MBI. Those shooters who had more experience did not incur as great of a stress response and also perfo1med better. HRV is an important factor in the psychophysiological influence on controlling perception and stress response reaction, regardless of impact on cardiac cycle rate, and should be used to assess military and police performance, especially under duress.
Application of the ram jet to vertical ascent

The purpose of this paper is to investigate the applicability of the ramjet to replace the first step of a two-step or multi-step rocket, with the hope of increasing the efficiency and performance of vertical ascent missiles of the present day. The ramjet is considered as a booster motor to boost the primary missile through the atmosphere. It is to be discarded from the primary missile after reaching its maximum velocity. To boost the ramjet to operating speed the second stage rocket must be operated for the first few seconds as a ducted rocket.

General ramjet performance is calculated graphically by using a step-by-step integration process to solve the differential equation of motion. The resulting flight velocity, fuel consumption per initial weight, and altitude are presented graphically in terms of time after launching the ramjet. It is assumed throughout the problem that gravity is constant and that the altitude necessary to start the ramjet is negligible. The acceleration of the missile is limited to 25 g's.

Important results present in this paper are: The most important factor that limits the performance of the ramjet is the air density ratio. The greatest increase in second-step launching altitude, by improved thrust and drag coefficients and increased ramjet cross-section area, is achieved at low ramjet launching velocities. The performance of the ramjet missile operating at a specific fuel consumption of .0007 [...] shows a marked increase of efficiency over a missile using a higher fuel consumption value. Missiles using a lower specific fuel consumption value, of the same order as the increased value, show negligible improvement in efficiency. When ramjet performance is compared to rocket performance; specifically, maximum velocity, altitude of maximum speed and altitude attained, the ramjet missile will burn only one third of the fuel required by a two-step rocket. Conversely, for the same fuel consumed, the ramjet missile will attain 65% more altitude than the two-step rocket.

description: A short derivation is given of the weak gravitational field approximation to the scalar massless propagator in Schwarzschild spacetime obtained by Paszko using the path-integral approach. The contribution from the direct coupling of the quantum field to the scalar curvature is explictly included. The propagator complies with Hadamard's pattern, and the vacuum state is consistent with the perturbative version of the Boulware vacuum. The momentum space propagator is computed for massless or massive particles to the same perturbative order. The renormalized value of $\ < ϕ^2(x)\ >$ for the massless case is reproduced.

description: The theorem of three circles in real algebraic geometry guarantees the termination and correctness of an algorithm of isolating real roots of a univariate polynomial. The main idea of its proof is to consider polynomials whose roots belong to a certain area of the complex plane delimited by straight lines. After applying a transformation involving inversion this area is mapped to an area delimited by circles. We provide a formalisation of this rather geometric proof in Ssreflect, an extension of the proof assistant Coq, providing versatile algebraic tools. They allow us to formalise the proof from an algebraic point of view.

description: We introduce a technique of time series analysis, potential forecasting, which is based on dynamical propagation of the probability density of time series. We employ polynomial coefficients of the orthogonal approximation of the empirical probability distribution and extrapolate them in order to forecast the future probability distribution of data. The method is tested on artificial data, used for hindcasting observed climate data, and then applied to forecast Arctic sea-ice time series. The proposed methodology completes a framework for `potential analysis' of tipping points which altogether serves anticipating, detecting and forecasting non-linear changes including bifurcations using several independent techniques of time series analysis. Although being applied to climatological series in the present paper, the method is very general and can be used to forecast dynamics in time series of any origin.

description: We present a novel Discontinuous Galerkin Finite Element Method for wave propagation problems. The method employs space-time Trefftz-type basis functions that satisfy the underlying partial differential equations and the respective interface boundary conditions exactly in an element-wise fashion. The basis functions can be of arbitrary high order, and we demonstrate spectral convergence in the $\Lebesgue_2$-norm. In this context, spectral convergence is obtained with respect to the approximation error in the entire space-time domain of interest, i.e. in space and time simultaneously. Formulating the approximation in terms of a space-time Trefftz basis makes high order time integration an inherent property of the method and clearly sets it apart from methods, that employ a high order approximation in space only.

description: In Fe-based superconductors, electron doping is often realized by the substitution of transition-metal atoms for Fe. In order to investigate how the electronic structure of the parent compound is influenced by Zn substitution, which supplies nominally four extra electrons per substituted atom but is expected to induce the strongest impurity potential among the transition-metal atoms, we have performed an angle-resolved photoemission spectroscopy measurements on Ba(Fe_{1-x}Zn_x)_2As_2 (Zn-122). In Zn-122, the temperature dependence of the resistivity shows a kink around T~135 K, indicating antiferromagnetic order below the Neel temperature of T_N ~ 135 K. In fact, folded Fermi surfaces (FSs) similar to those of the parent compound have been observed below T_N. The hole and electron FS volumes are, therefore, different from those expected from the rigid-band model. The results can be understood if all the extra electrons occupy the Zn 3d state ~10 eV below the Fermi level and do not participate in the formation of the FSs.

description: The present work is directed to the detection and analysis of notes, chords and other musical events produced by a stringed musical instrument, specifically the guitar. The chords generated by a guitar are polyphonic, meaning that they comprise multiple notes sounded simultaneously. Each note is also spectrally complex, in that it comprises a
fundamental tone and several harmonics. Despite this complexity, the statistics of the signal containing the notes and chords are expected to be similar to those of human speech. This similarity will allow the signal to be characterized as a parametric random process so that established mathematical and speech recognition techniques can be used
to extract the events from the signal. The analysis of musical signals is an important application since it is a logical extension to the problem of speech recognition.  Moreover, a robust computer-based solution to this problem could have both research and commercial applications.

A system for automated detection and analysis of musical events, such as notes and chords, has been designed. The system is comprised of two main elements: the event library and a set of match measures. The event library contains a hierarchy of event models each corresponding to a distinct musical note or chord. Each event model is structured as a hidden Markov model (HMM), λ = (A, B, π), having the four distinct states labeled attack, sustain, decay or silence, that correspond to the specific physical states of the musical event. Associated with each model state Q={q1, ••• , q4} are a set of M observation symbols V={ v1,v2, ••• , vM} and a set of three probability distributions: a transition probability distribution A={aij} , an observable probability distribution B={bj(k)} and an initial probability distribution π=π{i}. Three match measures are developed for solving the recognition problem: one for estimating the HMM parameters, one for determining the optimal state sequence of the HMM and one for evaluating the probability that a given observation sequence was produced by a specific HMM. The observation sequence is derived from the input signal by sampling, converting to a spectral representation, and digitally coding using standard speech recognition
techniques. The three match measures correspond, respectively, to training the model, refining the model and matching an event to a model, each of which is performed using conventional speech processing algorithms.
A unified model for the dynamics of driven ribbon with strain and magnetic order parameters

description: We develop a unified model to explain the dynamics of driven one dimensional ribbon for materials with strain and magnetic order parameters. We show that the model equations in their most general form explain several results on driven magnetostrictive metallic glass ribbons such as the period doubling route to chaos as a function of a dc magnetic field in the presence of a sinusoidal field, the quasiperiodic route to chaos as a function of the sinusoidal field for a fixed dc field, and induced and suppressed chaos in the presence of an additional low amplitude near resonant sinusoidal field. We also investigate the influence of a low amplitude near resonant field on the period doubling route. The model equations also exhibit symmetry restoring crisis with an exponent close to unity. The model can be adopted to explain certain results on magnetoelastic beam and martensitic ribbon under sinusoidal driving conditions. In the latter case, we find interesting dynamics of a periodic one orbit switching between two equivalent wells as a function of an ac magnetic field that eventually makes a direct transition to chaos under resonant driving condition. The model is also applicable to magnetomartensites and materials with two order parameters.

Longitudinal WW scattering in light of the "Higgs" discovery

Year: 2012
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: WW scattering is dominated at high energies by their longitudinal components, which are the most sensitive to the nature of the electroweak symmetry breaking. Prior to the discovery at the LHC of a Higgs-like particle, unitarization tools were extensively used to show that, in the absence of a light Higgs boson, new resonances resulting from the would-be strongly-interacting electroweak sector would appear, and furthermore these techniques would approximately predict their masses, widths, and signal strengths. With the discovery of a Higgs-like particle now firmly established, we re-investigate these techniques assuming this particle couples exactly as in the SM, but still being open to the possibility of an extended symmetry breaking sector. While the SM itself is free from problems with perturbative unitarity in the electroweak sector, "anomalous" self-couplings of the vector bosons -- low-energy remnants of such higher-energy symmetry breaking sectors -- are easily shown to re-introduce them. We demonstrate how new resonances should still appear in the scattering of EW vector bosons after imposing constraints from unitarity, and we discuss their ability to be probed with current and future LHC data.

The synthesis and solvolytic investigations of 2-hexanone-5-(p-N-methylpyridinium) ether and n-hexyl-p-carboxybenzenesulfonate

description: The synthesis and purification of 2-hexanone-5-(p-N-methylpyridinium) ether was accomplished. The reaction of this compound with aqueous NaOH failed to produce the desired products, cis- and trans-2-methylcyclopropylmethyl ketone. It appears that the desired anionic ring closure of the starting material did not take place, but instead, a simple displacement reaction occurred to produce 5-
hydroxyhexan-2-one.

In a second project, the synthesis of n-hexyl-p-carboxybenzene-sulfonate was attempted by two different routes. The first route involved esterification of p-carboxybenzenesulfonyl chloride and n-hexanol to form the desired sulfonate. This method proved unsuccessful, and
was abandoned. The second route involved oxidation of n-hexyl-p-toluenesulfonate to the carboxy compound. This method was successful, producing n-hexyl-p-carboxybenzenesulfonate in about 7% yield. This
molecule was found to have an approximate half-life of 14 hours when reacted with 1 N aqueous NaOD at room temperature.

description: In this paper, we propose an adaptive margin contrastive learning method for 3D point cloud semantic segmentation, namely AMContrast3D. Most existing methods use equally penalized objectives, which ignore per-point ambiguities and less discriminated features stemming from transition regions. However, as highly ambiguous points may be indistinguishable even for humans, their manually annotated labels are less reliable, and hard constraints over these points would lead to sub-optimal models. To address this, we design adaptive objectives for individual points based on their ambiguity levels, aiming to ensure the correctness of low-ambiguity points while allowing mistakes for high-ambiguity points. Specifically, we first estimate ambiguities based on position embeddings. Then, we develop a margin generator to shift decision boundaries for contrastive feature embeddings, so margins are narrowed due to increasing ambiguities with even negative margins for extremely high-ambiguity points. Experimental results on large-scale datasets, S3DIS and ScanNet, demonstrate that our method outperforms state-of-the-art methods.

description: Medial knee osteoarthritis is a disease that is projected to affect approximately 45% of the U.S. population and is associated with significant morbidity, chronic pain, and limited activity. Laterally wedged insoles are used as an intervention to laterally shift the mechanical axis of the limb and decrease the external knee adduction moment, possibly indicating a shift in load distribution to the lateral compartment of the knee. The aim of this study was to examine the acute effects of a laterally wedged insole in those with valgus and normally aligned knees and to determine prolonged effects after the insole was worn for a one week period in a healthy population. Ten females with normally aligned knees and eight females with valgus aligned knees participated in this study. Participants walked at a normal, comfortable speed with and without the insoles during two testing sessions, before and after a one week period of wearing the insoles. Three dimensional kinetics and kinematics were recorded. Each participant's mean data was analyzed using a two-way repeated measures ANOVA (group (normal, valgus) x condition (pre-wedge, pre-nonwedge, post-wedge, post-nonwedge)). The results demonstrated that the valgus aligned group exhibited a 0.17 Nm/kg reduction in knee abduction moment when compared to the normally aligned group (p=0.02). Also, the valgus aligned group had a lower knee abduction angular impulse (-0.10±0.01 Nms/kg) when compared to the normally aligned group (-0.16±0.01 Nms/kg) (p=0.00). There was a significant two-way interaction for vertical GRF at the instance of peak knee abduction moment (p=0.01). An independent t-test showed the valgus participants had a higher vertical GRF (12.04±1.42 N/kg) when compared to the normal participants (10.7±1.27 N/kg) during the post-nonwedge condition (p=0.046). A paired t-test revealed that the post-nonwedge condition exhibited a 0.40 N/kg decrease from the post-wedge condition in normal participants (p=0.006). Normal participants also exhibited a significant difference (p=0.007) between the post-nonwedge condition (10.7±1.27 N/kg) and the pre-wedge condition (11.2±0.89 N/kg). For the valgus group, participants exhibited a 0.43 N/kg decrease when the wedge was inserted during the post session (p=0.046). There was also a significant difference (p=0.045) between the post-nonwedge condition (12.0±1.42 N/kg) and the pre-nonwedge condition (11.4±1.20 N/kg). These results did not show a significant decrease in knee abduction moment; however, the differences seen in vertical GRF coincided with knee flexion angles. The valgus group demonstrated decreased vertical GRF and increased knee flexion with the insole, which could lead to a small decrease in knee abduction moment.

description: We investigate the interaction-induced superfluid-to-Mott insulator transition in the one-dimensional Bose-Hubbard model (BHM) for fillings $n=1$, $n=2$, and $n=3$ by studying the single-particle gap, the fidelity susceptibility, and the amplitude of Bloch oscillations via density-matrix renormalization-group methods. We apply a generic scaling procedure for the gap, which allows us to determine the critical points with very high accuracy. We also study how the fidelity susceptibility behaves across the phase transition. Furthermore, we show that in the BHM, and in a system of spinless fermions, the amplitude of Bloch oscillations after a tilt of the lattice vanishes at the critical points. This indicates that Bloch oscillations can serve as a tool to detect the transition point in ongoing experiments with ultracold gases.

description: Some aspects concerning the design of flexible nozzles for use in supersonic wind tunnels are discussed. Methods are investigated for matching the deflection patterns of nozzle plates and the theoretical aerodynamic shapes required for uniform, parallel, shockfree flow. Application of the design procedures to the Galcit 4" x 10", transonic wind tunnel is detailed. As a demonstration of a use of the tunnel, the Mach number of shock detachment from a 10[degree] wedge (half angle) is experimentally investigated.

description: Nuclease resistant chromatin subunits (ν bodies) were isolated from rat liver chromatin after digestion with DNAase II. Electron microscope studies showed them to be similar in size to particles which have been isolated from calf thymus chromatin and also to those seen in native chromatin. ν bodies prepared from native chromatin (ν(+F1)  and histone F1-depleted chromatin (ν(-F1)), as well as formaldehyde-fixed products from both these digestions (ν(FF + F1) and ν(FF-F1) were similar in size. For ν(+F1) the diameter was 80 ± 17 Å (n = 125); for ν(-F1), 87 ± 19 Å (n = 100); for ν(FF + F1), 96 ± 23 Å (n = 50); and for
ν(FF – F1) 81 ± 13 Å (n = 85). Multimer ν-body fractions did not show any obvious dimers, trimers, etc. , of monomer ν bodies. Sheared, isolated chromatin from rat liver was also examined using electron microscopy and was observed as networks of long thin strands (about 15 Å wide), interspersed with regions of either coiled single strands or strands covered with protein.

description: A sequence of moments encode the corresponding probability distribution. Probing if quantum joint probability distribution can be retrieved from the associated set of moments -- realized in the sequential measurement of a dichotomic observable at different time intervals -- reveals a negative answer i.e., the joint probabilities of sequential measurements do not agree with the ones obtained by inverting the moments. This is indeed a reflection of the non-existence of a bonafide grand joint probability distribution, consistent with all the physical marginal probability distributions. Here we explicitly demonstrate that given the set of moments, it is not possible to retrieve the three-time quantum joint probability distribution resulting from quantum sequential measurement of a single qubit dichotomic observable at three different times. Experimental results using a nuclear magnetic resonance (NMR) system are reported here to corroborate these theoretical observations viz., the incompatibility of the three-time joint probabilties with those extracted from the moment sequence.

A recipe for Hamiltonian of system-environment coupling applicable to ultrastrong light-matter interaction regime

description: When the light interacts with matters in a lossy cavity, in the standard cavity quantum electrodynamics, the dissipation of cavity fields is characterized simply by the strengths of the two couplings: the light-matter interaction and the system-environment coupling through the cavity mirror. However, in the ultrastrong light-matter interaction regime, the dissipation depends also on whether the two couplings are mediated by the electric field or the magnetic one (capacitive or inductive in superconducting circuits). Even if we know correctly the microscopic mechanism (Lagrangian) of the system-environment coupling, the coupling Hamiltonian itself is in principle modified due to the ultrastrong interaction in the cavity. In this paper, we show a recipe for deriving a general expression of the Hamiltonian of the system-environment coupling, which is applicable even in the ultrastrong light-matter interaction regime in the good-cavity and independent-transition limit.

description: (abridged) We studied the energy and frequency dependence of the Fourier time lags and intrinsic coherence of the kHz QPOs in the NS LMXBs 4U 1608-52 and 4U 1636-53 using RXTE data. In both sources we confirmed energy-dependent soft lags of 10-100 μs for the lower kHz QPO. We also found that the time lags of the upper kHz QPO are independent of energy and inconsistent with the soft lags of the lower kHz QPO. The intrinsic coherence of the lower kHz QPO remains constant at 0.6 from 5 to 12 keV, and then drops to zero, while for the upper kHz QPO the intrinsic coherence is consistent with zero across the full energy range. The intrinsic coherence of the upper kHz QPO is consistent with zero over the full frequency range of the QPO, except in 4U 1636-53 at ~780 Hz where it increases to 0.13. In 4U 1636-53, for the lower kHz QPO the 4-12 keV photons lag the 12-20 keV ones by 25 μs in the QPO frequency range 500-850 Hz, with the lags decreasing to 15 μs at higher frequencies. In 4U 1608-52 the soft lags of the lower kHz QPO remain constant at 40 μs. In 4U 1636-53, for the upper kHz QPO the 12-20 keV photons lag the 4-12 keV ones by 11 +/- 3 μs, independent of QPO frequency; we found consistent results for the time lags of the upper kHz QPO in 4U 1608-52. The intrinsic coherence of the lower kHz QPO increases from ~0-0.4 at 600 Hz to 1 and 0.6 at 800 Hz in 4U 1636-53 and 4U 1608-52, respectively. In 4U 1636-53 it decreases to 0.5 at 920 Hz, while in 4U 1608-52 we do not have data above 800 Hz. We discuss our results in the context of scenarios in which the soft lags are either due to reflection off the accretion disc or up-/down-scattering in a hot medium close to the neutron star. We finally explore the connection between, on one hand the time lags and the intrinsic coherence of the kHz QPOs, and on the other the QPOs' amplitude and quality factor in these two sources.

description: Sturm's oscillation theorem states that the n-th eigenfunction of a Sturm-Liouville operator on the interval has n-1 zeros (nodes). This result was generalized for all metric tree graphs and an analogous theorem was proven for discrete tree graphs. We prove the converse theorems for both discrete and metric graphs. Namely, if for all n, the n-th eigenfunction of the graph has n-1 zeros then the graph is a tree. Our proofs use a recently obtained connection between the graph's nodal count and the magnetic stability of its eigenvalues. In the course of the proof we show that it is not possible for all (or even almost all, in the metric case) the eigenvalues to exhibit a diamagnetic behaviour. In addition, we develop a notion of 'discretized' versions of a metric graph and prove that their nodal counts are related to this of the metric graph.
I. Interference during burning of body-centered cubic arrays of nine fuel droplets in air. II. Spray formation and evaporation

description: In order to gain some understanding of interference effects during the combustion and evaporation of fuel sprays, simple three-dimensional body-centered cubic arrays of nine n-heptane or nine methyl alcohol droplets burning in air have been studied. Different cube sizes were used to vary the amount of interference obtained during combustion of the droplets. Photographic studies of the center droplet in this nine-droplet array were made in order to determine the qualitative effects of droplet spacing on the evaporation constant (K') while combustion was in progress and to determine whether the mass rate of burning was proportional to the first power of droplet diameter for a three-dimensional array of droplets.

Experimental results indicate that, when the droplets are in close proximity and the flames completely merged, the evaporation constant is reduced by 40 percent below the value obtained for minimum interference. A 25 percent increase in the evaporation constant over single-droplet values for K' was noted when the droplet spacing was altered to reduce local heat losses from the flame fronts. The results obtained from studies of the center droplet substantiate Probert's assumption (Ref. 38) that the square of droplet diameter decreases linearly with time.

Unsuccessful attempts to study the combustion of liquid bipropellant mixtures and to examine the "burning" of red fuming nitric acid in an ammonia atmosphere are described.

In Part II, a general discussion of information available on the disintegration of liquid jets, spray characteristics, mean droplet size, droplet-size distribution, and spray evaporation is presented. The use of similarity considerations in analyzing spray-nozzle performance is demonstrated. Calculation of K' for a spray from experimental spray evaporation data is described and the results of these calculations tabulated.
