description: Wireless sensor network consists of large number of tiny sensor nodes which are usually deployed in a harsh environment. Self configuration and infrastructure less are the two fundamental properties of sensor networks. Sensor nodes are highly energy constrained devices because they are battery operated devices and due to harsh environment deployment it is impossible to change or recharge their battery. Energy conservation and prolonging the network life are two major challenges in a sensor network. Communication consumes the large portion of WSN energy. Several protocols have been proposed to realize power- efficient communication in a wireless sensor network. Cluster based routing protocols are best known for increasing energy efficiency, stability and network lifetime of WSNs. Low Energy Adaptive Clustering Hierarchy (LEACH) is an important protocol in this class. One of the disadvantages of LEACH is that it does not consider the nodes energy and distance for the election of cluster head. This paper proposes a new energy efficient clustering protocol DE-LEACH for homogeneous wireless sensor network which is an extension of LEACH. DE-LEACH elects cluster head on the basis of distance and residual energy of the nodes. Proposed protocol increases the network life, stability and throughput of sensor network and simulations result shows that DE-LEACH is better than LEACH.

description: We consider the problem

 u''(x,t) = uxx(x,t) + λ(t) ΣNk=1αkδ(x-ξk), 0 < x < 1,0 < t < T
 u(x,0) = u'(x,0) = 0, 0 < x < 1
 u(0,t) = u(1,t) = 0, 0 < t < T,

 where u'(x,t) = ∂u ⁄ ∂t, (x,t), u'' (x,t) = ∂2u ⁄ ∂t2 (x,t), and λ ∈ C1[0,T], αk ≠ 0, ∈ ℝ, ξk ∈ (0,1), and δ(·-ξk) is Dirac's delta function at ξk, 1 ≤ k ≤ n. Our task consists in the determination of N, αk, ξk, 1 ≤ k ≤ N from the boundary observation ∂u ⁄ ∂x (0,t), 0 < t < T, where λ and T > 0 are given. We prove the uniqueness, give a stability estimate and provide a scheme for reconstructing α1, α2, ξ1, ξ2 from ∂u ⁄ ∂x (0,t), 0 < t < T in the case N = 2.

description: Increasing amounts of sensor-augmented research objects have been used in design research. We call these objects Data-Enabled Objects, which can be integrated into daily activities capturing data about people's detailed whereabouts, behaviours and routines. These objects provide data perspectives on everyday life for contextual design research. However, data-enabled objects are still computational devices with limited privacy awareness and nuanced data sharing. To better design data-enabled objects, we explore privacy design spaces by inviting 18 teams of undergraduate design students to re-design the same type of sensor-enabled home research camera. We developed the Connected Peekaboo Toolkit (CPT) to support the design teams in designing, building, and directly deploying their prototypes in real home studies. We conducted Thematic Analysis to analyse their outcomes which led us to interpret that privacy is not just an obstacle but can be a driver by unfolding an exploration of possible design spaces for data-enabled objects.

description: We report on a case study in programming an early quantum annealer to attack optimization problems related to operational planning. While a number of studies have looked at the performance of quantum annealers on problems native to their architecture, and others have examined performance of select problems stemming from an application area, ours is one of the first studies of a quantum annealer's performance on parametrized families of hard problems from a practical domain. We explore two different general mappings of planning problems to quadratic unconstrained binary optimization (QUBO) problems, and apply them to two parametrized families of planning problems, navigation-type and scheduling-type. We also examine two more compact, but problem-type specific, mappings to QUBO, one for the navigation-type planning problems and one for the scheduling-type planning problems. We study embedding properties and parameter setting, and examine their effect on the efficiency with which the quantum annealer solves these problems. From these results we derive insights useful for the programming and design of future quantum annealers: problem choice, the mapping used, the properties of the embedding, and the annealing profile all matter, each significantly affecting the performance.

description: 3D reconstruction from videos has become increasingly popular for various applications, including navigation for autonomous driving of robots and drones, augmented reality (AR), and 3D modeling. This task often combines traditional image/video processing algorithms and deep neural networks (DNNs). Although recent developments in deep learning have improved the accuracy of the task, the large number of calculations involved results in low computation speed and high power consumption. Although there are various domain-specific hardware accelerators for DNNs, it is not easy to accelerate the entire process of applications that alternate between traditional image/video processing algorithms and DNNs. Thus, FPGA-based end-to-end acceleration is required for such complicated applications in low-power embedded environments. This paper proposes a novel FPGA-based accelerator for DeepVideoMVS, a DNN-based depth estimation method for 3D reconstruction. We employ HW/SW co-design to appropriately utilize heterogeneous components in modern SoC FPGAs, such as programmable logic (PL) and CPU, according to the inherent characteristics of the method. As some operations are unsuitable for hardware implementation, we determine the operations to be implemented in software through analyzing the number of times each operation is performed and its memory access pattern, and then considering comprehensive aspects: the ease of hardware implementation and degree of expected acceleration by hardware. The hardware and software implementations are executed in parallel on the PL and CPU to hide their execution latencies. The proposed accelerator was developed on a Xilinx ZCU104 board by using NNgen, an open-source high-level synthesis (HLS) tool. Experiments showed that the proposed accelerator operates 60.2 times faster than the software-only implementation on the same FPGA board with minimal accuracy degradation.

Lorentz-violating effects in three-dimensional $QED$

Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Inspired in discussions presented lately regarding Lorentz-violating interaction terms in \cite{13,6}, we propose here a slightly different version for the coupling term. We will consider a modified quantum electrodynamics with violation of Lorentz symmetry defined in a $\left( 2+1\right) $-dimensional spacetime. We define the Lagrangian density with a Lorentz-violating interaction, where the the spacetime dimensionality is explicitly taken into account in its definition. The work encompasses an analysis of this model at both zero and finite-temperature, where very interesting features are known to occur due to the spacetime dimensionality. With that in mind we expect that the spacetime dimensionality may provide new insights about the radiative generation of higher-derivative terms into the action, implying in a new Lorentz-violating electrodynamics, as well the nonminimal coupling may provide interesting implications on the thermodynamical quantities.

We recall the results of McEliece et al.

description: Symmetry breaking is reported for continuous families of solitons in the nonlinear Schrödinger equation with a two-dimensional complex potential. This symmetry-breaking bifurcation is forbidden in generic complex potentials. However, for a special class of partially parity-time-symmetric potentials, such symmetry breaking is allowed. At the bifurcation point, two branches of asymmetric solitons bifurcate out from the base branch of symmetry-unbroken solitons. Stability of these solitons near the bifurcation point are also studied, and two novel stability properties for the bifurcated asymmetric solitons are revealed. One is that at the bifurcation point, zero and simple imaginary linear-stability eigenvalues of asymmetric solitons can move directly into the complex plane and create oscillatory instability. The other is that the two bifurcated asymmetric solitons, even though having identical powers and being related to each other by spatial mirror reflection, can possess different types of unstable eigenvalues and thus exhibit non-reciprocal nonlinear evolutions under random-noise perturbations.

description: Charge radii of neutron deficient 40Sc and 41Sc nuclei were determined using collinear laser spectroscopy. With the new data, the chain of Sc charge radii extends below the neutron magic number N=20 and shows a pronounced kink, generally taken as a signature of a shell closure, but one notably absent in the neighboring Ca, K and Ar isotopic chains. Theoretical models that explain the trend at N=20 for the Ca isotopes cannot reproduce this puzzling behavior.

description: At ambient conditions, the Fe$_3$O$_4$(001) surface shows a $(\sqrt{2}\times \sqrt{2})R45^o$ reconstruction that has been proposed as the surface analog of the bulk phase below the Verwey transition temperature, T$_V$. The reconstruction disappears at a high temperature, T$_S$, through a second order transition. We calculate the temperature evolution of the surface electronic structure based on a reduced bulk unit cell of P2/m symmetry that contains the main features of the bulk charge distribution. We demonstrate that the insulating surface gap arises from the large demand of charge of the surface O, at difference with that of the bulk. Furthermore, it is coupled to a significant restructuration that inhibits the formation of trimerons at the surface. An alternative bipolaronic charge distribution emerges below T$_S$, introducing a competition between surface and bulk charge orders below T$_V$.

description: The early-type galaxy NGC 5195 (alternatively known as M51b) possesses extended gas features detected in multi-wavelength, postulated to be associated with previous activities of the central supermassive black hole (SMBH). Using integral field spectroscopic observations from the Canada-France-Hawaii Telescope (CFHT)/SITELLE, we report on the discovery of a new large-scale ionized gas structure traced by [O III], [N II], and H$α$ line emission, extending to $\sim10\rm\,kpc$ from the nucleus of NGC 5195. Its bipolar morphology, emission line ratio diagnostics, and comparison with the X-ray image from Chandra and low-frequency radio data from LOFAR all indicate that it is likely an outflow inflated by a past episode of elevated active galactic nucleus (AGN) activity. Assuming the ionized gas is outflowing from the central region of NGC 5195, the estimated mass and energy outflow rates are $\dot{M}_{\rm out} = 3.5-27.9 \rm\, M_{\odot}\, yr^{-1}$ and $\dot{E}_{\rm out} = 0.98-7.9\times10^{40}\rm\, erg\, s^{-1}$, respectively, which cannot be provided by current star formation and the low luminosity nucleus. Alternatively, considering the history of gravitational interaction between the M51 pair and the presence of HI tidal tail, the northern large-scale ionized gas could very likely be associated with tidally stripped material illuminated by a luminous AGN in the past.

description: We investigate new solutions for magnetized neutron stars with a barotropic core in magnetohydrodynamic (MHD) equilibrium and a magneto-elastic crust, which was neglected by previous studies concerning stars in MHD equilibrium. The Lorentz force of the barotropic star is purely irrotational and the structures of magnetic fields are constrained. By contrast, a solenoidal component of the Lorentz force exists in the elastic crust and the structures of the magnetic fields are less restricted. We find that the minor solenoidal component in the elastic crust is important for sustaining the strong magnetic field in the core. Unlike previous studies, the toroidal magnetic field exists in the entire region of the core, and we obtain equilibrium states with large toroidal magnetic fields, where the toroidal magnetic energy is larger than the poloidal magnetic energy. The elastic force of the crust sustains an order of $10^{15}~\mathrm{G}$ toroidal magnetic field in the core, and the maximum strength of the toroidal magnetic field is approximately proportional to the crust thickness.

description: A number of methods have been proposed recently which exploit multiple highly-correlated interpretations of events, or of jets within an event. For example, Qjets reclusters a jet multiple times and telescoping jets uses multiple cone sizes. Previous work has employed these methods in pseudo-experimental analyses and found that, with a simplified statistical treatment, they give sizable improvements over traditional methods. In this paper, the improvement gain from multiple event interpretations is explored with methods much closer to those used in real experiments. To this end, we derive a generalized extended maximum likelihood procedure. We study the significance improvement in Higgs to bb with both this method and the simplified method from previous analysis. With either method, we find that using multiple jet radii can provide substantial benefit over a single radius. Another concern we address is that multiple event interpretations might be exploiting similar information to that already present in the standard kinematic variables. By examining correlations between kinematic variables commonly used in LHC analyses and invariant masses obtained with multiple jet reconstructions, we find that using multiple radii is still helpful even on top of standard kinematic variables when combined with boosted decision trees. These results suggest that including multiple event interpretations in a realistic search for Higgs to bb would give additional sensitivity over traditional approaches.

description: We study the time evolution of sub-Keplerian transonic accretion flow onto a non-rotating black hole using a three-dimensional, inviscid hydrodynamics simulation code. Prior two-dimensional simulations show that centrifugal barrier in the accreting matter may temporarily halt the nearly free-falling matter and produce a stable, geometrically thick disk which may contain turbulent eddies. Our goal in this work is to investigate whether the disk develops any instability because of this turbulence when we dynamically activate all three dimensions. We find that the disk remains stable and axisymmetric even close to the central black hole. However, if we explicitly apply non-axisymmetric azimuthal perturbation, the axisymmetric structure of the disk is destroyed and instability is developed.

As it will be shown, the fermionic mass contributes to the Green's functions in a surprisingly simple way, leaving therefore the original nonperturbative nature of the massless results still intact in the massive theory. Also, by means of complementarity, we present a second discussion of the massive model, now at its bosonic representation.

description: Quasi-periodic pulsations (QPPs) are frequently detected in solar and stellar flares, but the underlying physical mechanisms are still to be ascertained. Here, we show microwave QPPs during a solar flare originating from quasi-periodic magnetic reconnection at the flare current sheet. They appear as two vertically detached but closely related sources with the brighter ones located at flare loops and the weaker ones along the stretched current sheet. Although the brightness temperatures of the two microwave sources differ greatly, they vary in phase with periods of about 10--20 s and 30--60 s. The gyrosynchrotron-dominated microwave spectra also present a quasi-periodic soft-hard-soft evolution. These results suggest that relevant high-energy electrons are accelerated by quasi-periodic reconnection, likely arising from the modulation of magnetic islands within the current sheet as validated by a 2.5-dimensional magnetohydrodynamic simulation.
A systematic study of Rayleigh-Brillouin scattering in air, N2 and O2 gases
Creators: name: Gu, Ziyu

Publisher: name: arXiv
Year: 2014

description: Spontaneous Rayleigh-Brillouin scattering experiments in air, N2 and O2 have been performed for a wide range of temperatures and pressures at a wavelength of 403 nm and at a 90 degrees scattering angle. Measurements of the Rayleigh-Brillouin spectral scattering profile were conducted at high signal-to-noise ratio for all three species, yielding high-quality spectra unambiguously showing the small differences between scattering in air, and its constituents N2 and O2. Comparison of the experimental spectra with calculations using the Tenti S6 model, developed in 1970s based on linearized kinetic equations for molecular gases, demonstrates that this model is valid to high accuracy. After previous measurements performed at 366 nm, the Tenti S6 model is here verified for a second wavelength of 403 nm. Values for the bulk viscosity for the gases are derived by optimizing the model to the measurements. It is verified that the bulk viscosity parameters obtained from previous experiments at 366 nm, are valid for wavelengths of 403 nm. Also for air, which is treated as a single-component gas with effective gas transport coefficients, the Tenti S6 treatment is validated for 403 nm as for the previously used wavelength of 366 nm, yielding an accurate model description of the scattering profiles for a range of temperatures and pressures, including those of relevance for atmospheric studies. It is concluded that the Tenti S6 model, further verified in the present study, is applicable to LIDAR applications for exploring the wind velocity and the temperature profile distributions of the Earth's atmosphere. Based on the present findings, predictions can be made on the spectral profiles for a typical LIDAR backscatter geometry, which deviate by some 7 percent from purely Gaussian profiles at realistic sub-atmospheric pressures occurring at 3-5 km altitude in the Earth's atmosphere.
PREVENTING TENNIS ELBOW: SIMPLE MEASURES FOR A PAIN-FREE GAME
Creators: name: Rahul Rajeev
Publisher: name: PHYSIOZINE
Year: 2025

description: Tennis elbow, a common affliction among sports enthusiasts and commoners can be a major  setback for all. However, with the right preventive measures, you can reduce your risk and  enjoy an injury-free game. 

 

The Importance of Prevention 

Tennis elbow's unpredictable nature makes prevention crucial. While treatment options are  available, preventing the condition altogether is ideal. By taking proactive steps, players can  avoid the discomfort, pain, and potential long-term damage associated with tennis elbow. 

 

Targeted Exercises and Stretches 

Targeted exercises and stretches are essential in preventing tennis elbow. Strengthening  extension, flexion, and rotational movements greatly reduce risk. These exercises improve  forearm, wrist, and elbow strength, enhancing overall stability. 

 

Proper Equipment Fit and Technique 

Proper equipment fit and technique adjustments also play vital roles in prevention. Ensure  your grip size and racket weight are suitable for your playing style. Additionally, focus on  proper serving, forehand, and backhand techniques to minimize strain. 

 

Beyond Tennis: Prevention for All 

Prevention extends beyond tennis or sports. Household ladies often face challenges, as  diagnosis typically precedes treatment. Simple adjustments, however, can make a difference.  Adjusting the heights of kitchen slabs to one’s height or even personalised kitchen tools to  one’s physical activity is advisable.IT professionals can benefit from positioning their mouse  and keyboard closer to their body, while everyone can reduce strain by keeping frequently  used items within easy reach. Treatments are always personalised and individualised. It's  never the same for X and Y.  

 

Cultural Influence on Prevention 

Interestingly, cultural gestures also influence prevention. Indian culture promotes gestures  like folded hands, and keeping hands close to the body, whereas Western traditions involve  extending hands away from the body. Embracing cultural heritage and blending it with  ergonomic practices can help mitigate the risk of tennis elbow and other repetitive strain  injuries. 

 

Benefits of Prevention 

By adopting these preventive measures, individuals can: 

• Reduce the risk of tennis elbow and repetitive strain injuries 

• Promote a pain-free life 

• Enhance overall well-being

• Improve performance and productivity 

• Enjoy an active, healthy lifestyle 

 

Conclusion 

Preventing tennis elbow requires a proactive approach. Individuals can significantly reduce  their risk by incorporating targeted exercises, proper equipment fit, and technique  adjustments. Embracing cultural heritage and ergonomic practices further enhances  prevention. Take control of your health and enjoy a pain-free game.

description: It is shown that the single $0^+$ THSR (Tohsaki-Horiuchi-Schuck-Röpke) wave function which is extended to include 2$α$ correlation is almost completely equivalent to the 3$α$ wave function obtained as the full solution of 3$α$ cluster model. Their squared overlap is as high as 98\% while it is 93\% if the 2$α$ correlation is not included. This result implies that, by incorporating the 2$α$ correlation in the 3$α$ model, the ground state of $^{12}$C is describable in the container picture which is valid for the Hoyle state for which the 2$α$ correlation is weak and a single $0^+$ THSR wave function without 2$α$ correlation is almost completely equivalent to the full solution of 3$α$ cluster model.

However, rendering the correct pitch accents is still a challenging problem for end-to-end TTS.

We investigate the effects of features captured by PnG~BERT on Japanese TTS by modifying the fine-tuning condition to determine the conditions helpful inferring pitch accents. We manipulate content of PnG~BERT features from being text-oriented to speech-oriented by changing the number of fine-tuned layers during TTS. In addition, we teach PnG~BERT pitch accent information by fine-tuning with tone prediction as an additional downstream task. Our experimental results show that the features of PnG~BERT captured by pretraining contain information helpful inferring pitch accent, and PnG~BERT outperforms baseline Tacotron on accent correctness in a listening test.

description: Recently, it has been shown that temporal metamaterials based on impulsive modulations of the constitutive parameters (of duration much smaller than a characteristic electromagnetic timescale) may exhibit a nonlocal response that can be harnessed so as to perform elementary analog computing on an impinging wavepacket. These short-pulsed metamaterials can be viewed as the temporal analog of conventional (spatial) metasurfaces. Here, inspired by the analogy with cascaded metasurfaces, we leverage this concept and take it one step further, by showing that short-pulsed metamaterials can be utilized as elementary bricks for more complex computations. To this aim, we develop a simple, approximate approach to systematically model the multiple actions of time-resolved short-pulsed metamaterials. Via a number of representative examples, we illustrate the computational capabilities enabled by this approach, in terms of simple and composed operations, and validate it against a rigorous numerical solution. Our results indicate that the temporal dimension may provide new degrees of freedom and design approaches in the emerging field of computational metamaterials, in addition or as an alternative to conventional spatially variant platforms.

Generalization Bounds for Inductive Matrix Completion in Low-noise Settings

description: We study inductive matrix completion (matrix completion with side information) under an i.i.d. subgaussian noise assumption at a low noise regime, with uniform sampling of the entries. We obtain for the first time generalization bounds with the following three properties: (1) they scale like the standard deviation of the noise and in particular approach zero in the exact recovery case; (2) even in the presence of noise, they converge to zero when the sample size approaches infinity; and (3) for a fixed dimension of the side information, they only have a logarithmic dependence on the size of the matrix. Differently from many works in approximate recovery, we present results both for bounded Lipschitz losses and for the absolute loss, with the latter relying on Talagrand-type inequalities. The proofs create a bridge between two approaches to the theoretical analysis of matrix completion, since they consist in a combination of techniques from both the exact recovery literature and the approximate recovery literature.

description: We present an analysis of mid-and far-infrared (IR) spectrum and spectral energy distribution (SED) of the LBV R71 in the LMC.This work aims to understand the overall contribution of high-mass LBVs to the total dust-mass budget of the interstellar medium (ISM) of the LMC and compare this with the contribution from low-mass asymptotic giant branch (AGB) stars. As a case study, we analyze the SED of R71. We compiled all the available photometric and spectroscopic observational fluxes from various telescopes for a wide wavelength range (0.36 -- 250\,$μ$m). We determined the dust composition from the spectroscopic data, and derived the ejected dust mass, dust mass-loss rate, and other dust shell properties by modeling the SED of R71. We noted nine spectral features in the dust shell of R71 by analyzing Spitzer spectroscopic data. Among these, we identified three new crystalline silicate features. We computed our model spectrum by using 3D radiative transfer code MCMax. Our model calculation shows that dust is dominated by amorphous silicates, with some crystalline silicates, metallic iron, and a very tiny amount of polycyclic aromatic hydrocarbon (PAH) molecules. The presence of both silicates and PAHs indicates that the dust has a mixed chemistry. We derived a dust mass of 0.01 M$_\odot$, from which we arrive at a total ejected mass of $\approx$ 5 M$_\odot$. This implies a time-averaged dust mass-loss rate of 2.5$\times$10$^{-6}$ M$_\odot$\,yr$^{-1}$ with an explosion about 4000 years ago. We assume that the other five confirmed dusty LBVs in the LMC loose mass at a similar rate, and estimate the total contribution to the mass budget of the LMC to be $\approx$ 10$^{-5}$ M$_\odot$\,yr$^{-1}$, which is comparable to the contribution by all the AGB stars in the LMC. Based on our analysis on R71, we speculate that LBVs as a class may be an important dust source in the ISM of the LMC.

description: In this paper we present a technique of NLP to tackle the problem of inference relation (NLI) between pairs of sentences in a target language of choice without a language-specific training dataset. We exploit a generic translation dataset, manually translated, along with two instances of the same pre-trained model - the first to generate sentence embeddings for the source language, and the second fine-tuned over the target language to mimic the first. This technique is known as Knowledge Distillation. The model has been evaluated over machine translated Stanford NLI test dataset, machine translated Multi-Genre NLI test dataset, and manually translated RTE3-ITA test dataset. We also test the proposed architecture over different tasks to empirically demonstrate the generality of the NLI task. The model has been evaluated over the native Italian ABSITA dataset, on the tasks of Sentiment Analysis, Aspect-Based Sentiment Analysis, and Topic Recognition. We emphasise the generality and exploitability of the Knowledge Distillation technique that outperforms other methodologies based on machine translation, even though the former was not directly trained on the data it was tested over.
