description: Wireless links can exhibit high error rates due to attenuation, fading, or interfering active radiation sources. To make matters worse, error rates can be highly variable due to changes in the wireless environment. Researchers and developers have explored a wide range of solutions to optimize communication in this difficult error environment, including traditional end-to-end solutions, link-layer solutions, and solutions involving layer four processing inside the network. A significant challenge is ensuring that systems with multiple layers of error control avoid compromising performance by duplication of effort. We argue and demonstrate that protocol-independent link-level local error control can achieve high communication efficiency even in a highly variable error environment, that adaptation is important to achieve this efficiency, and that inter-layer coexistence is achievable. The logical link control layer of our WaveLAN-based experimental LAN includes three error control mechanisms: local retransmission, adaptive packet shrinking, and adaptive error coding. Measurements generated on a variety of network topologies and trace-based error environments demonstrate the TCP performance improvements and good coexistence with TCP's end-to-end retransmission strategy

description: We consider the problem of non-adaptive noiseless group testing of $N$ items of which $K$ are defective. We describe four detection algorithms: the COMP algorithm of Chan et al.; two new algorithms, DD and SCOMP, which require stronger evidence to declare an item defective; and an essentially optimal but computationally difficult algorithm called SSS. By considering the asymptotic rate of these algorithms with Bernoulli designs we see that DD outperforms COMP, that DD is essentially optimal in regimes where $K \geq \sqrt N$, and that no algorithm with a nonadaptive Bernoulli design can perform as well as the best non-random adaptive designs when $K > N^{0.35}$. In simulations, we see that DD and SCOMP far outperform COMP, with SCOMP very close to the optimal SSS, especially in cases with larger $K$.
Edge states and the integer quantum Hall conductance in spin-chiral ferromagnetic kagome lattice

description: We investigate the chiral edge states in the two-dimensional ferromagntic kagomé lattice with spin anisotropies included. The system is periodic in the $x$ direction but has two edges in the $y$ direction. The Harper equation for solving the energies of edge states is derived. We find that there are two edge states in each bulk energy gap, corresponding to two zero points of the Bloch function on the complex-energy Riemann surface (RS). The edge-state energy loops parametrized by the momentum $k_{x}$ cross the holes of the RS. When the Fermi energy lies in the bulk energy gap, the quantized Hall conductance is given by the winding number of the edge states across the holes, which reads as $σ_{xy}^{\text{edge}}$=$-\frac{e^{2}}{h}% $sgn$(\sinϕ) $, where $ϕ$ is the spin chiral parameter (see text). This result keeps consistent with that based on the topological bulk theory.

description: We show that in a two-component Bose gas with Rashba spin-orbit coupling (SOC) two atoms can form bound states (Rashbons) with any intra-species scattering length. At zero center-of-mass momentum there are two degenerate Rashbons due to time-reversal symmetry, but the degeneracy is lifted at finite in-plane momentum with two different effective masses. A stable Rashbon condensation can be created in a dilute system with weakly attractive intra-species and repulsive inter-species interactions. The critical temperature of Rashbon condensation is about six times smaller than the BEC transition temperature of an ideal Bose gas. Due Rashba SOC, excitations in the Rashbon condensation phase are anisotropic in momentum space.

description: Despite the increasing degree of multi-homing, path and data redundancy, and capacity available in the Internet, today's clients experience outage rates of a few percent when accessing Web sites. MONET ("Multi-homed Overlay NETwork), is a new system that improves client availability to Web sites using a combination of link multi-homing and a cooperative overlay network of peer proxies to obtain a diverse collection of paths between clients and Web sites. This approach creates many potential paths between clients and Web sites, requiring a scalable way to selecting a good path. MONET solves this problem using a waypoint selection algorithm, which picks a good small subset of all available paths to actively probe. MONET runs on FreeBSD, Linux, and Mac OS X, and is deployed at six different sites. These installations have been running MONET for over one year, serving about fifty users on a daily basis. Our analysis of proxy traces shows that the proxy network avoids between 60% and 94% of observed failures, including access link failures, Internet routing problems, persistent path congestion, and DNS failures. The proxy avoids nearly 100% of failures due to client and wide-area network failures, with negligible overhead.

description: In view of highly decentralized and diversified power generation concepts, in particular with renewable energies such as wind and solar power, the analysis and control of the stability and the synchronization of power networks is an important topic that requires different levels of modeling detail for different tasks. A frequently used qualitative approach relies on simplified nonlinear network models like the Kuramoto model. Although based on basic physical principles, the usual formulation in form of a system of coupled ordinary differential equations is not always adequate. We present a new energy-based formulation of the Kuramoto model as port-Hamiltonian system of differential-algebraic equations. This leads to a very robust representation of the system with respect to disturbances, it encodes the underlying physics, such as the dissipation inequality or the deviation from synchronicity, directly in the structure of the equations, it explicitly displays all possible constraints and allows for robust simulation methods. Due to its systematic energy based formulation the model class allows easy extension, when further effects have to be considered, higher fidelity is needed for qualitative analysis, or the system needs to be coupled in a robust way to other networks. We demonstrate the advantages of the modified modeling approach with analytic results and numerical experiments.

description: Thread-level speculation (TLS) allows us to automatically parallelize general-purpose programs by supporting parallel execution of threads that might not actually be independent. In this paper, we show that the key to good performance ties in the three different ways to communicate a value between speculative threads: speculation, synchronization and prediction. The difficult part is deciding how and when to apply each method. This paper shows how we can apply value prediction, dynamic synchronization and hardware instruction prioritization to improve value communication and hence performance in several SPECint benchmarks that have been automatically transformed by our compiler to exploit TLS. We find that value prediction can be effective when properly throttled to avoid the high costs of mis-prediction, while most of the gains of value prediction can be more easily achieved by exploiting silent stores. We also show that dynamic synchronization is quite effective for most benchmarks, while hardware instruction prioritization is not. Overall, we find that these techniques have great potential for improving the performance of TLS.

The method, applied to the unfolding process of the alpha-helix form of an alanine deca-peptide, gives results in good agreement with thermodynamic integration.

description: In many situations we are interested in the propagation of energy in some portions of a three dimensional system with dilute long-range links. In this paper sandpile model is defined on the three-dimensional small world network with real dissipative boundaries and the energy propagation is studied in three-dimensions as well as the two-dimensional cross sections. Two types of cross section are defined in the system, one in the bulk and another in the system boundary. The motivation of this is to make clear how the statistics of the avalanches in the bulk cross section tend to the statistics of the dissipative avalanches, defined in the boundaries as the concentration of long range links ($α$) increases. This trend is numerically shown to be power law in a manner described in the paper. Two regimes of $α$ are considered in this work. For sufficiently small $α$s the dominant behavior of the system is just like that of the regular BTW, whereas for the intermediate values the behavior is non-trivial with some exponents that are reported in the paper. It is shown that the spatial extent up to which the statistics is similar to the regular BTW model scales with $α$ just like the dissipative BTW model with the dissipation factor (mass in the corresponding ghost model) $m^2\sim α$ for the three-dimensional system as well as its two-dimensional cross-sections.

With respect to previous treatments of the problem, our analysis is exact and valid for all values of the external force field, and it is expressed via unique formulæ valid for all initial conditions and parameters of the system. The simple form of the solution allows us to perform a thorough investigation of the properties of the dynamical system, including the identification of quasi-periodic and periodic orbits, the formulation of a simple analytical criterion to determine the boundness of the trajectory, and the characterisation of the equilibrium points.

description: Baryogenesis, through the decays of heavy bosons, was considered to be one of the major successes of the grand unified theories (GUTs). It was then realized that the sphaleron processes erased any baryon asymmetry from the GUT-baryogenesis at a later stage. In this paper, we discuss the idea of resurrecting GUT-baryogenesis in a large class of SO(10) GUTs. Our analysis shows that fast lepton number violating but baryon number conserving processes can partially wash out the GUT-baryogenesis produced lepton and/or baryon asymmetry associated with or without the sphaleron and/or Yukawa interactions.

description: In atherosclerosis cholesterol accumulation in arterial walls forms plaques which lead to associated cardiovascular diseases. High-density lipoprotein (HDL) nanoparticles known as “good cholesterol” transport cholesterol from arterial plaques to the liver for excretion. Therefore, HDL and its components have been targeted for tackling atherosclerosis treatment. Significantly, carriers of the R173C or L144R mutation in the major HDL protein apolipoprotein A-I (apoA-I) have low levels of HDL with a low atherosclerosis incidence. This suggests the mutations are atheroprotective as wild-type (WT) apoA-I carriers have a higher risk of atherosclerosis with low HDL levels. However, the mechanism for the mutants atheroprotective function is unknown. This work compares the molecular structure of reconstituted HDL (rHDL) nanoparticles containing the apoA-I variants using biophysical techniques. To determine if the rHDL structure affects the nanoparticle function and aid atherosclerosis treatment development. The expression and purification of unlabelled and uniformly [13C/15N]-labelled recombinant apoA-I variants was established. rHDL nanoparticles were prepared containing POPC, ±cholesterol, and apoA-I using detergent-mediated dialysis and density-based ultracentrifugation. The rHDL nanoparticle size and morphology were analysed with techniques such as NativePAGE gradient gel electrophoresis and transmission electron microscopy (TEM). A novel morphology characterisation was developed using 31P solid-state NMR spectroscopy of oriented rHDL nanoparticles on glass substrates. Three distinct rHDL nanoparticle morphologies were identified that were inaccessible by TEM. The rHDL-L144R nanoparticles showed a different surface curvature when compared to the rHDL-WT and R173C nanoparticles. Subtle differences in the protein secondary structure were identified by circular dichroism and high-resolution 2D 13C-13C NMR spectra of PEG-precipitated rHDL-WT and L144R nanoparticles. Consequently, the different rHDL nanoparticle morphologies detected could be connected to the atheroprotective functional properties of the rHDL-L144R nanoparticles. The morphology characterisation technique was applied to a plasma HDL sample which provides a framework for application to clinical samples.

description: In this paper we define a rigid rational homotopy type, associated to any variety $X$ over a perfect field $k$ of positive characteristic. We prove comparison theorems with previous definitions in the smooth and proper, and log-smooth and proper case. Using these, we can show that if $k$ is a finite field, then the Frobenius structure on the higher rational homotopy groups is mixed. We also define a relative rigid rational homotopy type, and use it to define a homotopy obstruction for the existence of sections.

description: We implemented the neutrino dark energy proposal in a left-right symmetric model. Unlike earlier models of mass varying neutrinos, in the present model the mass parameter that depends on the scalar field (acceleron) remains very light naturally. The required neutrino masses then predicts the U(1)_R breaking scale to be in the TeV range, providing new signals for LHC. Compared to all other neutrino dark energy proposals, this model has the added advantage that it can also be embedded into a grand unified theory. In this scenario leptogenesis occurs through decays of scalars at very high energy.

description: We propose a novel method for using the World Wide Web to acquire trigram estimates for statistical language modeling. We submit an N-gram as a phrase query to web search engines. The search engines return the number of web pages containing the phrase, from which the N-gram count is estimated. The N-gram counts are then used to form web-based trigram probability estimates. We discuss the properties of such estimates, and methods to interpolate them with traditional corpus based trigram estimates. We show that the interpolated models improve speech recognition word error rate signiﬁcantly over a small test set.

description: Due to increasing urban population and growing number of motor vehicles, traffic congestion is becoming a major problem of the 21st century. One of the main reasons behind traffic congestion is accidents which can not only result in casualties and losses for the participants, but also in wasted and lost time for the others that are stuck behind the wheels. Early detection of an accident can save lives, provides quicker road openings, hence decreases wasted time and resources, and increases efficiency. In this study, we propose a preliminary real-time autonomous accident-detection system based on computational intelligence techniques. Istanbul City traffic-flow data for the year 2015 from various sensor locations are populated using big data processing methodologies. The extracted features are then fed into a nearest neighbor model, a regression tree, and a feed-forward neural network model. For the output, the possibility of an occurrence of an accident is predicted. The results indicate that even though the number of false alarms dominates the real accident cases, the system can still provide useful information that can be used for status verification and early reaction to possible accidents.
Coupling of $c=-2$ and $c=\frac{1}{2}$ and $c=0$ conformal field theories: The geometrical point of view

description: The coupling of the $c=-2$, $c=\frac{1}{2}$ and $c=0$ conformal field theories are numerically considered in this paper. As the prototypes of the couplings, $(c_1=-2)\oplus (c_2=0)$ and $(c_1=-2)\oplus (c_2=\frac{1}{2})$, we consider the BTW model on the 2D square critical site-percolation and the BTW model on Ising-correlated percolation lattices respectively. Some geometrical techniques are used to characterize the presumable conformal symmetry of the resultant systems. Using the Schramm-Loewrner evolution (SLE), we find that the algebra of the central charges of the coupled models is closed, namely the former case results to two-dimensional self-avoiding walk (SAW) fixed point corresponding to $c=0$ conformal field theory, whereas the latter one results to the two-dimensional critical Ising fixed point corresponding to the $c=\frac{1}{2}$ conformal field theory.

description: The rapid influx and exodus of refugees could not have come at a more controversial time as Turkey is suffering its worst economic crisis of the century and the Syrian refugee count was at an all time high. The Turkish President, Recep Tayyip Erdogan, is looking for solutions to migratory and financial problems in the country. However, the solution may lie in the intersection of the two. Although it may be politically unpopular, Turkey must retain top talent, encourage refugee innovation, and allow incoming migrants to fill labor gaps to revive their struggling economy.
A Critical Exploration of the Effects of English Language Instruction in Colombian Higher Education on Low-income Students’ Capability Formation

description: English is the most widely spoken language in the world, and many higher education institutes (HEIs) in the global South have prioritised English language education (ELE). In Colombia, the context of this study, English has become the de facto foreign language in Colombian higher education (HE) although little is known about its effects on the lives of HE students from low-income backgrounds. Addressing this knowledge gap is critical to ensure that ELE in Colombian HE is relevant and socially just. The current study used the capability approach (CA) to identify the substantive freedoms which English can enlarge or constrain in the lives of economically vulnerable graduates in Colombia, and to identify factors which are instrumental in this process. Since Sen and Nussbaum’s normative framework has given insufficient consideration to questions of power and inequality, this study also draws on Phillipson’s (1992) theory of linguistic imperialism. Qualitative interviews with 20 economically vulnerable graduates and four HE experts in the field of Colombian ELE were conducted to investigate this issue, and thematic analysis was used to analyse the data. The findings show that English in Colombia, although implicated in global injustices, can cultivate economic, sociocultural and epistemic capabilities. However, they also show how this capability expansion is also shaped by a range of conversion factors. This thesis builds on the small number of qualitative studies exploring the relationship between English and development in the global South and extends this literature by improving our understanding of this relationship in the Colombian context, including the ways in which the spread of English can perpetuate asymmetrical North-South power relations. It also makes a valuable contribution to the capability literature by highlighting the importance of viewing linguistic capabilities as dynamic and relational. The findings of this thesis are therefore of interest not only to language policy experts and other language education stakeholders in developing contexts, but also to capability scholars.

It is here shown how such a solution exists and is elegantly expressed in terms of the Weierstrass elliptic and related functions. Previously known facts can be derived from the new explicit solution and new insights are revealed.

description: This paper describes our work on applying ensembles of acoustic models to the problem of large vocabulary continuous speech recognition (LVCSR). We propose three algorithms for constructing ensembles. The first two have their roots in bagging algorithms; however, instead of randomly sampling examples our algorithms construct training sets based on the word error rate. The third one is a boosting style algorithm. Different from other boosting methods which demand large resources for computation and storage, our method present a more efficient solution suitable for acoustic model training. We also investigate a method that seeks optimal combination for models. We report experimental results on a large real world corpus collected from the Carnegie Mellon Communicator dialog system. Significant improvements on system performance are observed in that up to 15.56% relative reduction on word error rate is achieved.

description: We present an efficient and scalable algorithm for segmenting 3D RGBD point clouds by combining depth, color, and temporal information using a multistage, hierarchical graph-based approach. Our algorithm processes a moving window over several point clouds to group similar regions over a graph, resulting in an initial over-segmentation. These regions are then merged to yield a dendrogram using agglomerative clustering via a minimum spanning tree algorithm. Bipartite graph matching at a given level of the hierarchical tree yields the final segmentation of the point clouds by maintaining region identities over arbitrarily long periods of time. We show that a multistage segmentation with depth then color yields better results than a linear combination of depth and color. Due to its incremental processing, our algorithm can process videos of any length and in a streaming pipeline. The algorithm's ability to produce robust, efficient segmentation is demonstrated with numerous experimental results on challenging sequences from our own as well as public RGBD data sets.

description: We demonstrate the advantages of feedforward loops using a Boolean network, which is one of the discrete dynamical models for transcriptional regulatory networks. After comparing the dynamical behaviors of network embedded feedback and feedforward loops, we found that feedforward loops can provide higher temporal order (coherence) with lower entropy (randomness) in a temporal program of gene expression. In addition, complexity of the state space that increases with longer length of attractors and greater number of attractors is also reduced for networks with more feedforward loops. Feedback loops show opposite effects on dynamics of the networks. These results suggest that feedforward loops are one of the favorable local structures in biomolecular and neuronal networks.

Harmony Perception by Periodicity Detection

Year: 2013

description: The perception of consonance/dissonance of musical harmonies is strongly correlated with their periodicity. This is shown in this article by consistently applying recent results from psychophysics and neuroacoustics, namely that the just noticeable difference between pitches for humans is about 1% for the musically important low frequency range and that periodicities of complex chords can be detected in the human brain. Based thereon, the concepts of relative and logarithmic periodicity with smoothing are introduced as powerful measures of harmoniousness. The presented results correlate significantly with empirical investigations on the perception of chords. Even for scales, plausible results are obtained. For example, all classical church modes appear in the front ranks of all theoretically possible seven-tone scales.

Tilted-axis wobbling in odd-mass nuclei

description: A triaxial rotor Hamiltonian with a rigidly aligned high-$j$ quasiparticle is treated by a time-dependent variational principle, using angular momentum coherent states. The resulting classical energy function have three unique critical points in a space of generalized conjugate coordinates, which can minimize the energy for specific ordering of the inertial parameters and a fixed angular momentum state. Due to the symmetry of the problem, there are only two unique solutions, corresponding to wobbling motion around a principal axis and respectively a tilted-axis. The wobbling frequencies are obtained after a quantization procedure and then used to calculate $E2$ and $M1$ transition probabilities. The analytical results are employed in the study of the wobbling excitations of $^{135}$Pr nucleus, which is found to undergo a transition from low angular momentum transverse wobbling around a principal axis toward a tilted-axis wobbling at higher angular momentum.

Improving Prehensile Mobile Manipulation Performance through Experience Reuse

description: During pick and place tasks, a mobile manipulator performs recurring relative moves within the close proximities of the object of interest and the destination independent of their global poses. These moves are usually critical to the success of the manipulation attempt and hence need to be executed delicately. Considering the critical yet recurring nature of these moves, we let the robot memorize them as state-action sequences and reuse them whenever possible to guide manipulation planning and execution. When combined with a sampling-based generative planner, this guidance helps reduce planning time by deliberately biasing the planning process towards the feasible sequences. Additionally, monitoring the execution while reiterating the reached sequences improves task success rate. Our experiments show that this complementary combination of the already available partial plans and executions with the ones generated from scratch yields to fast, reliable, and repeatable solutions.
Leading two-loop Yukawa corrections to the pole masses of SUSY fermions in the MSSM

description: We have calculated the leading Yukawa corrections to the chargino, neutralino and gluino pole masses in the DR-bar scheme in the Minimal Supersymmetric Standard Model (MSSM) with the full set of complex parameters. We have performed a numerical analysis for a particular point in the parameter space and found typical corrections of a few tenths of a percent thus exceeding the experimental resolution as expected at the ILC. We provide a computer program which calculates two-loop pole masses for SUSY fermions with complex parameters up to the respective order in pertubation theory.

description: Formation of blood vessels at required number and time during bone regeneration represents a major challenge for tissue engineered constructs. Poor revascularization leads to scaffold failure and consequently, the loss of the implant. There are several problems associated with the use of growth factors in clinic such as low stability, controlled delivery to the site, and high price. Heparin is known to bind with angiogenic growth factors influencing the process of new blood vessels formation. The aim of the present study was to explore the potential of heparin to produce pro-angiogenic bone regeneration materials. Heparin was electrostatically loaded onto composite materials from porous chitosan/hydroxyapatite scaffolds. Different concentrations of heparin were successfully loaded onto the scaffolds, and the release performance of the scaffold was analysed by toluidine blue assay showing that the scaffolds loaded with lowest concentration provide a sustained release. The angiogenic activity of the heparin loaded synthesized materials was evaluated by chorioallantoic membrane (CAM) assay. After six day of materials implantation on CAM it was noted that overall low heparin concentrations exhibited a positive effect, with approximately 28μg per scaffold showed a significant increment in blood vessels. The synthesized materials showed no cytotoxic effects when evaluated by using U2OS cell line. Also, as showed by the SEM images the scaffolds exhibited that interconnected porosity and a pore size able to support osteoblasts proliferation. This research provides information about the pro-angiogenic effect of heparin in potential bone regeneration materials.
The angle of repose of spherical grains in granular Hele-Shaw cells: A molecular dynamics study

description: We report the results of three dimensional molecular dynamic simulations on the angle of repose of a sandpile formed by pouring mono-sized cohesionless spherical grains into a granular Hele-Shaw cell. In particular, we are interested to investigate the effects of those variables which may impact significantly on pattern formation of granular mixtures in Hele-Shaw cells. The results indicate that the frictional forces influence remarkably the formation of pile on the grain level. Furthermore, We see that increasing grain insertion rate decreases slightly the angle of repose. We also find that in accordance with experimental results, the cell thickness is another significant factor and the angle of repose decays exponentially by increasing the cell thickness. It is shown that this effect can be interpreted as a cross-over from two to three dimensions. In fact, using grains with different sizes shows that the behaviour of the angle of repose when both size and cell thickness are varied is controlled by a scaled function of the ratio of these two variables.
