description: Background: Allergic Rhinitis (AR) is a common variable of immune responses, affecting nearly 50 crores people worldwide. So, this study addresses both western and traditional Chinese medicinal practices to combine and mediate a potent result in treating AR patients. Objective: To achieve a sustainable and long term impact of a treatment consisting of western medicines like synthetic corticosteroids and non-sedative antihistamine combined with the traditional Chinese medicine acupoint herbal patching on the Allergic Rhinitis patients. Methods: Total 782 patients were included in this study. They were randomly divided into four groups maintaining approximately 1:1:1:1. The first group of patients were treated with Loratadine Tablet 10 mg and Mometasone furoate NS 200 microg (administered once in the morning at waking up and in empty stomach for 15 days) with placebo traditional Chinese medicine. While the second group of patients received the traditional Chinese medicine acupoint herbal patching with placebo tablets (Vitamin C, 100 mg). Now the third group was the integrated treatment group where the patients received both the treatments and the fourth group received only the placebos for both the treatment procedures. Results: Different scales were employed to examine the different symptoms of AR, like, Visual Analog Scale (VAS), Total Nasal Symptom Score (TNSS), Total Symptom Score (TSS) etc. To measure the histological effects in response of the allergic reaction in AR in the patients, random blood testing was conducted. Statistical analysis was done in SPSS 17.0. Mean ± standard deviation (x–±s) was used to evaluate the continuous and normally distributed data. Geometric mean and standard deviation; ANOVA; Dunnett's test were done to determine any multiple comparisons if found. Then Chi square test was used for recapitulating data. Conclusion: The study is a great success in achieving its result on the AR patients. But, to come with a definite sustainable result, the time period of the study is needed to be increased for at least a year, so that the effectiveness of this treatment on the changing seasons can be observed and thus statistically analysed.

description: Option pricing is a fundamental problem in financial sector. This work presents a hardware accelerator on FPGAs for Option Pricing using Crank-Nicolson Finite Difference scheme for solving the Black-Scholes PDE. A variant of Cyclic Reduction called normalized Cyclic Reduction algorithm is used as Tridiagonal Solver. The thesis contains all the theoretical background of option pricing models and finite difference schemes. A literature review had been carried out covering extensively all the FPGA based option pricing accelerators. The effort of this work was concentrated mainly to hardware low-level optimizations that were implemented to produce a parallel system that scale up efficiently. These optimizations, such as custom precision arithmetic, fused operators, pipelined designs etc., were on level of hardware design and had scope to produce a highly parallel hardware architecture. Three different hardware architectures for the main computation core were presented. First a naïve non-pipelined at 32bit precision, next a pipelined architecture using a custom 3 operand adder, also at 32bit precision and finally the proposed hardware architecture with a Fused Multiply Addition operator (FMA or fmadd). This architecture was implemented with 48bit precision, which was selected after taking into account error analysis with MPRF library and design decisions. The implementation was on a Xilinx FPGA device, Ultrascale xcvu9p, and achieved clock frequency 263MHZ.

description: While ventricular electromechanics is extensively studied, four-chamber heart models have only been addressed recently; most of these works however neglect atrial contraction. Indeed, as atria are characterized by a complex physiology influenced by the ventricular function, developing computational models able to capture the physiological atrial function and atrioventricular interaction is very challenging. In this paper, we propose a biophysically detailed electromechanical model of the whole human heart that considers both atrial and ventricular contraction. Our model includes: i) an anatomically accurate whole-heart geometry; ii) a comprehensive myocardial fiber architecture; iii) a biophysically detailed microscale model for the active force generation; iv) a 0D closed-loop model of the circulatory system; v) the fundamental interactions among the different core models; vi) specific constitutive laws and model parameters for each cardiac region. Concerning the numerical discretization, we propose an efficient segregated-intergrid-staggered scheme and we employ recently developed stabilization techniques that are crucial to obtain a stable formulation in a four-chamber scenario. We are able to reproduce the healthy cardiac function for all the heart chambers, in terms of pressure-volume loops, time evolution of pressures, volumes and fluxes, and three-dimensional cardiac deformation, with unprecedented matching (to the best of our knowledge) with the expected physiology. We also show the importance of considering atrial contraction, fibers-stretch-rate feedback and suitable stabilization techniques, by comparing the results obtained with and without these features in the model. The proposed model represents the state-of-the-art electromechanical model of the iHEART ERC project and is a fundamental step toward the building of physics-based digital twins of the human heart.

description: Many compelling dark matter (DM) scenarios feature Coulomb-like interactions between DM particles and baryons, in which the cross section for elastic scattering scales with relative particle velocity as $v^{-4}$. Previous studies have invoked such interactions to produce heat exchange between cold DM and baryons and alter the temperature evolution of hydrogen. In this study, we present a comprehensive study of the effects of Coulomb-like scattering on structure formation, in addition to the known effects on the thermal history of hydrogen. We find that interactions which significantly alter the temperature of hydrogen at Cosmic Dawn also dramatically suppress the formation of galaxies that source the Lyman-$α$ background, further affecting the global 21-cm signal. In particular, an interaction cross section at the current observational upper limit leads to a decrease in the abundance of star-forming halos by a factor of $\sim 2$ at $z\sim 20$, relative to cold, collisionless DM. We also find that DM that is 100% millicharged cannot reproduce the depth and the timing of the reported EDGES anomaly in any part of the parameter space. These results critically inform modeling of the global 21-cm signal and structure formation in cosmologies with DM-baryon scattering, with repercussions for future and upcoming cosmological data analysis.

description: Squashed entanglement and its universal upper bound, the quantum conditional mutual information, are faithful measures of bipartite quantum correlations defined in terms of multipartitions. As such, they are sensitive to the fine-grain structure of quantum systems. Building on this observation, we introduce the concept of quantum conditional mutual information between the edges of quantum many-body systems. We show that this quantity characterizes unambiguously one-dimensional topological insulators and superconductors, being equal to Bell-state entanglement in the former and to half Bell-state entanglement in the latter, mirroring the different statistics of the edge modes in the two systems. The edge-to-edge quantum conditional mutual information is robust in the presence of disorder or local perturbations, converges exponentially with the system size to a quantized topological invariant, even in the presence of interactions, and vanishes in the trivial phase. We thus conjecture that it coincides with the edge-to-edge squashed entanglement in the entire ground-state phase diagram of symmetry-protected topological systems, and we provide some analytical evidence supporting the claim. By comparing them with the entanglement negativity, we collect further indications that the quantum conditional mutual information and the squashed entanglement provide a very accurate characterization of nonlocal correlation patterns in one-dimensional quantum matter.

description: Background: The high prevalence rate of childhood and adolescence obesity has thrown a global threat over the past few decades. This situation has propelled the scientists towards searching for the definite biological and social factors resulting in obesity so that a stable and appropriate preventive strategies can be established in early life. Objective: The objective of this study was to detect subgroups showing segmental developing phases in the course of life with distinctive weight gain trajectories and identifying the probable reasons behind this onset of obesity in childhood & early adulthood. Methods: The child survey was mediated by a group of trained interviewers to assess &evaluate each child with their mothers and their family’s environment. Mothers were thoroughly informed and the consent papers were signed by them moreover willingness from children were also recorded. For statistical analysis, the Hierarchical Generalized Linear Modeling (HGLM) method (developed using HLM software) was applied to study longitudinal effect on developmental obesity trajectory. Results: Results clearly indicate that maternal obesity, smoking and alcohol consumption in pregnancy directly exert effect on growing trajectory of BMI. These responses are the important proof of the perinatal environment influencing the onset of obesity. The findings say, characteristics of environment, genetic factors may contribute, but excessive maternal weight and smoking in pregnancy are important predictor of childhood and adolescent obesity. Smoking of mother is suspected to limit the growth of the foetus which leads to low birth weight, which causes uncontrolled and fast development and thus obesity occurs, known as compensatory rapid postnatal growth. Discussion: High maternal weight, maternal smoking am alcohol consumption in pregnancy, low educational qualification of the mother and lack of breastfeeding in infant were factors contributing in elevating the onset of childhood and adolescent obesity. Conclusion: The outcomes of this study clearly allude that these advance risk factors must be controlled and thus these must be taken in account while designing preventive interventions.

description: In many daily-life scenarios, acoustic sources recorded in an enclosure can only be observed with other interfering sources. Hence, convolutive Blind Source Separation (BSS) is a central problem in audio signal processing. Methods based on Independent Component Analysis (ICA) are especially important in this field as they require only few and weak assumptions and allow for blindness regarding the original source signals and the acoustic propagation path. Most of the currently used algorithms belong to one of the following three families: Frequency Domain ICA (FD-ICA), Independent Vector Analysis (IVA), and TRIple-N Independent component analysis for CONvolutive mixtures (TRINICON). While the relation between ICA, FD-ICA and IVA becomes apparent due to their construction, the relation to TRINICON is not well established yet. This paper fills this gap by providing an in-depth treatment of the common building blocks of these algorithms and their differences, and thus provides a common framework for all considered algorithms.

description: Recent advances in ambient, FM backscatter radio showed the feasibility of
piggybacking an audio signal on top of a broadcast FM radio transmission.
In conjunction with the weak transmission power inherent in backscatter ra-
dio systems, this work exploits FM ambient backscatter to achieve covert
communication. Information in the form of plain text is converted to a wide-
band audio signal using Direct Sequence Spread Spectrum (DSSS) modula-
tion, resulting in a noise-like audio signal undergoing Frequency Modulation
(FM) before being backscattered to a conventional smart phone equipped
with FM radio, acting as the receiver. A Linear Feedback Shift Register
(LFSR), provided with a key completely determining its output, generates
the symbol sequences that serve as spreading sequences in DSSS, thus adding
a Private-Key Encryption layer to enhance the cryptosystem's robustness. A
Repetition Code is utilized as a way of error correction to increase the per-
formance. Besides simulations, a prototype was implemented to verify the
feasibility of the proposed concept.

description: Developing adhesives whose bond strength can be externally manipulated is a topic of considerable interest for practical and scientific purposes. In this work, we propose a method of controlling the adhesion force of a regular fluid, such as water and/or glycerol, confined between two parallel plates by applying an external electric field. Our results show the possibility of enhancing or diminishing the bond strength of the liquid sample by appropriately tuning the intensity and direction of the electric current generated by the applied electric field. Furthermore, we verify that, for a given direction of the electric current, the adhesion force can be reduced enough for the fluid to lose its adhesive properties and begin exerting a force to move apart the confining plates. In these circumstances, we obtain an analytical expression for the minimum electric current required to detach the plates without requiring the action of an external force.

description: In the last six months, fluctuations in the daily SARS-CoV-2 mortality rate on five continents have been synchronous.
 This indicates the global nature of the cause of these fluctuations, So the effect of which is observed simultaneously on different continents.
 The only global factor that can account for such precise and coordinated fluctuations on the five continents is climate and atmospheric factors.
 A close look at the details of the chart above for the last 6 months shows that the fluctuations start on the South American continent and then transfer to the rest of the continents with a delay of few days.
 The release of iodine from the surface of the ocean and then its movement in the atmosphere as atmospheric iodine, which can play a hormonal and regulatory role in the body after inhalation, can be a candidate for the latent factor.
 This means that in addition to its important infectious dimension, COVID-19 disease also has an allergic or hormonal dimension in exacerbating the condition.

description: We show that a variant of the Gross-Neveu Yukawa model with disorder provides a real, nonsupersymmetric generalization of the Sachdev-Ye Kitaev (SYK) model to three dimensions. The model contains $M$ real scalar fields and $N$ Dirac (or Majorana) fermions, interacting via a Yukawa interaction with a local Gaussian random coupling in three dimensions. In the limit where $M$ and $N$ are both large, and the ratio $M/N$ is held fixed, the model defines a line of infrared fixed points parametrized by $M/N$, reducing to the Gross-Neveu vector model when $M/N=0$. When $M/N$ is nonzero, the model is dominated by melonic diagrams and gives rise to SYK-like physics. We compute the spectrum of single-trace operators in the theory, and find that it is real for all values of $M/N$.

description: Deep Neural Networks (DNNs) based Synthetic Aperture Radar (SAR) Automatic Target Recognition (ATR) systems have shown to be highly vulnerable to adversarial perturbations that are deliberately designed yet almost imperceptible but can bias DNN inference when added to targeted objects. This leads to serious safety concerns when applying DNNs to high-stake SAR ATR applications. Therefore, enhancing the adversarial robustness of DNNs is essential for implementing DNNs to modern real-world SAR ATR systems. Toward building more robust DNN-based SAR ATR models, this article explores the domain knowledge of SAR imaging process and proposes a novel Scattering Model Guided Adversarial Attack (SMGAA) algorithm which can generate adversarial perturbations in the form of electromagnetic scattering response (called adversarial scatterers). The proposed SMGAA consists of two parts: 1) a parametric scattering model and corresponding imaging method and 2) a customized gradient-based optimization algorithm. First, we introduce the effective Attributed Scattering Center Model (ASCM) and a general imaging method to describe the scattering behavior of typical geometric structures in the SAR imaging process. By further devising several strategies to take the domain knowledge of SAR target images into account and relax the greedy search procedure, the proposed method does not need to be prudentially finetuned, but can efficiently to find the effective ASCM parameters to fool the SAR classifiers and facilitate the robust model training. Comprehensive evaluations on the MSTAR dataset show that the adversarial scatterers generated by SMGAA are more robust to perturbations and transformations in the SAR processing chain than the currently studied attacks, and are effective to construct a defensive model against the malicious scatterers.

description: The equations of motion of a mechanical system subjected to nonholonomic linear constraints can be formulated in terms of a linear almost Poisson structure in a vector bundle. We study the existence of invariant measures for the system in terms of the unimodularity of this structure. In the presence of symmetries, our approach allows us to give necessary and sufficient conditions for the existence of an invariant volume, that unify and improve results existing in the literature. We present an algorithm to study the existence of a smooth invariant volume for nonholonomic mechanical systems with symmetry and we apply it to several concrete mechanical examples.

description: Background: Lesbian, bisexual, and queer (LBQ) women exhibit high rates of alcohol and tobacco use, yet there is limited qualitative research examining why. Previous research has focused on minority stress explanations, linking alcohol and tobacco use to experiences of discrimination. However, other work considers the social contexts and cultural practices associated with alcohol and tobacco consumption. This confirms the need for more in-depth understandings of LBQ women’s lived experiences in a contemporary Australian context. Aims: To address gaps in existing research, this project aims to develop a more nuanced contemporaneous theorising of what alcohol and tobacco mean to LBQ women in Australia. Drawing on feminist and critical drugs studies, this research will examine the complexities of alcohol and tobacco in LBQ women’s lives, including how patterns of use change over time. We will also critically consider how LBQ women understand risk in relation to these substances, including factors leading to harm reduction and help-seeking. Method: We will employ a longitudinal qualitative approach to explore LBQ women’s experiences over time, including three waves of semi-structured interviews and participant photography. We aim to recruit approximately 60 women in Victoria and New South Wales. Interview and visual data will be analysed using a range of narrative and thematic techniques. Conclusion: This study seeks to explore the complexities of individual experiences with alcohol and tobacco use, including pleasure and support-seeking, and to provide a nuanced understanding of the cultural dimensions of use that may change over time. In doing so, we propose a shift from deficit approaches to LBQ women’s substance use towards more meaningful strengths-based engagement with the function of substances for LBQ women. Findings will be significant in their contribution to the current understandings of substance use patterns among LBQ women and the implications for harm reduction and health interventions.

description: We attempt to establish links between a summary curve, or modulus summary curve, MSC, of the solar background magnetic field (SBMF) derived from Principal Component Analysis, with the averaged sunspot numbers (SSN). The comparison of MSC with the whole set of SSN reveals rather close correspondence of cycle timings, duration and maxima times for the cycles 12- 24, 6,7 and -4,-3. Although, in 1720-1760 and 1830-1860 there are discrepancies in maximum amplitudes of the cycles, durations and shifts of the maximum times between MSC and SSN curves. The MSC curve reveals pretty regular cycles with double maxima (cycles 1-4), triple maximum amplitude distributions for cycles 0 and 1 and for cycles -1 and -2 just before Maunder minimum. The MSC cycles in 1700-1750 reveal smaller maximal magnitudes in cycles -3 to 0 and in cycle 1-4 than the amplitudes of SSN, while cycles -2 to 0 have reversed maxima with minima with SSN. Close fitting of MSC or Bayesian models to the sunspot curve distorts the occurrences of either Maunder Minimum or/and modern grand solar minimum (2020-2053). These discrepancies can be caused by poor observations and by difference in solar magnetic fields responsible for these proxies. The dynamo simulations of toroidal and poloidal magnetic field in the grand solar cycle (GSC) from 1650 until 2050 demonstrate the clear differences between their amplitude variations during the GSC. The use of eigen vectors of SBMF can provide additional information to that derived from SSN that can be useful for understanding solar activity.

description: The fundamental problem of weighted sampling involves sampling of satisfying assignments of Boolean formulas, which specify sampling sets, and according to distributions defined by pre-specified weight functions to weight functions. The tight integration of sampling routines in various applications has highlighted the need for samplers to be incremental, i.e., samplers are expected to handle updates to weight functions. The primary contribution of this work is an efficient knowledge compilation-based weighted sampler, INC, designed for incremental sampling. INC builds on top of the recently proposed knowledge compilation language, OBDD[AND], and is accompanied by rigorous theoretical guarantees. Our extensive experiments demonstrate that INC is faster than state-of-the-art approach for majority of the evaluation. In particular, we observed a median of 1.69X runtime improvement over the prior state-of-the-art approach.

description: Quantum many-body scar states are special eigenstates of nonintegrable models with distinctive entanglement features that give rise to infinitely long-lived coherent dynamics under quantum quenches from certain initial states. We elaborate on a construction of quantum many-body scar states in which they emerge from Einstein-Podolsky-Rosen (EPR) states in systems with two layers, wherein the two layers are maximally entangled. We apply this construction to spin systems as well as systems of itinerant fermions and bosons and demonstrate how symmetries can be harnessed to enhance its versatility. We show that several well-known examples of quantum many-body scars, including the tower of states in the spin-1 XY model and the $η$-pairing states in the Fermi-Hubbard model, can be understood within this formalism. We also demonstrate how an {\it infinite} tower of many-body scar states can emerge in bilayer Bose-Hubbard models with charge conservation.

description: We present a catalog of about 25,000 images of massive ($M_{\star} \ge 10^9 M_{\odot}$) galaxies at redshift $3 \leq z \leq 6$ from the TNG50 cosmological simulation, tailored for observations at multiple wavelengths carried out with JWST. The synthetic images were created with the SKIRT radiative transfer code, including the effects of dust attenuation and scattering. The noiseless images were processed with the mirage simulator to mimic the Near Infrared Camera (NIRCam) observational strategy (e.g., noise, dithering pattern, etc.) of the Cosmic Evolution Early Release Science (CEERS) survey. In this paper, we analyze the predictions of the TNG50 simulation for the size evolution of galaxies at $3 \leq z \leq 6$ and the expectations for CEERS to probe that evolution. In particular, we investigate how sizes depend on wavelength, redshift, mass, and angular resolution of the images. We find that the effective radius accurately describes the three-dimensional half-mass radius of TNG50 galaxies. Sizes observed at 2~$μ$m are consistent with those measured at 3.56~$μ$m at all redshifts and masses. At all masses, the population of higher-$z$ galaxies is more compact than their lower-$z$ counterparts. However, the intrinsic sizes are smaller than the mock observed sizes for the most massive galaxies, especially at $z \lesssim 4$. This discrepancy between the mass and light distribution may point to a transition in the galaxy morphology at $z$=4-5, where massive compact systems start to develop more extended stellar structures.

description: In this article, we study the ramification of the Gauss map of complete minimal surfaces in R^3 and R^4 on annular ends. We obtain results which are similar to the ones obtained by Fujimoto and Ru for (the whole) complete minimal surfaces, thus we show that the restriction of the Gauss map to an annular end of such a complete minimal surface cannot have more branching (and in particular not avoid more values) than on the whole complete minimal surface. We thus give an improvement of the results on annular ends of complete minimal surfaces of Kao.

description: We investigate the time evolution of bias of cosmic density fields. We perform numerical simulations of the evolution of the cosmic web for the conventional $Λ$ cold dark matter ($Λ$CDM) model. The simulations cover a wide range of box sizes $L=256 - 1024\Mpc$, and epochs from very early moments $z=30$ to the present moment $z=0$. We calculate spatial correlation functions of galaxies, $ξ(r)$, using dark matter particles of the biased $Λ$CDM simulation. We analyse how these functions describe biasing properties of the evolving cosmic web. We find that for all cosmic epochs the bias parameter, defined through the ratio of correlation functions of selected samples and matter, depends on two factors: the fraction of matter in voids and in the clustered population, and the luminosity (mass) of galaxy samples. Gravity cannot evacuate voids completely, thus there is always some unclustered matter in voids, thus the bias parameter of galaxies is always greater than unity, over the whole range of evolution epochs. We find that for all cosmic epochs bias parameter values form regular sequences, depending on galaxy luminosity (particle density limit), and decreasing with time.

description: Hierarchy seems to pervade complexity in both living and artificial systems. Despite its relevance, no general theory that captures all features of hierarchy and its origins has been proposed yet. Here we present a formal approach resulting from the convergence of theoretical morphology and network theory that allows constructing a 3D morphospace of hierarchies and hence comparing the hierarchical organization of ecological, cellular, technological and social networks. Embedded within large voids in the morphospace of all possible hierarchies, four major groups are identified. Two of them match the expected from random networks with similar connectivity, thus suggesting that non-adaptive factors are at work. Ecological and gene networks define the other two, indicating that their topological order is the result of functional constraints. These results are consistent with an exploration of the morphospace using in silico evolved networks.

The Cosmophenomenology of Axionic Dark Radiation

description: Relativistic axions are good candidates for the dark radiation for which there are mounting observational hints. The primordial decays of heavy fields produce axions which are ultra-energetic compared to thermalised matter and inelastic axion-matter scattering can occur with $E_{CoM} \gg T_γ$, thus accessing many interesting processes which are otherwise kinematically forbidden in standard cosmology. Axion-photon scattering into quarks and leptons during BBN affects the light element abundances, and bounds on overproduction of $^4$He constrain a combination of the axion decay constant and the reheating temperature. For supersymmetric models, axion scattering into visible sector superpartners can give direct non-thermal production of dark matter at $T_γ \ll T_{freezeout}$. Most axions --- or any other dark radiation candidate from modulus decay --- still linger today as a Cosmic Axion Background with $E_{axion} \sim \mathcal{O}(100) eV$, and a flux of $\sim 10^6 cm^{-2} s^{-1}$.

description: This paper synthesizes a gain-scheduled controller to stabilize all possible Linear Parameter-Varying (LPV) plants that are consistent with measured input/state data records. Inspired by prior work in data informativity and LTI stabilization, a set of Quadratic Matrix Inequalities is developed to represent the noise set, the class of consistent LPV plants, and the class of stabilizable plants. The bilinearity between unknown plants and `for all' parameters is avoided by vertex enumeration of the parameter set. Effectiveness and computational tractability of this method is demonstrated on example systems.

Predicting Failure times for some Unobserved Events with Application to Real-Life Data

description: This study aims to predict failure times for some units in some lifetime experiments. In some practical situations, the experimenter may not be able to register the failure times of all units during the experiment. Recently, this situation can be described by a new type of censored data called multiply-hybrid censored data. In this paper, the linear failure rate distribution is well-fitted to some real-life data and hence some statistical inference approaches are applied to estimate the distribution parameters. A two-sample prediction approach applied to extrapolate a new sample simulates the observed data for predicting the failure times for the unobserved units.
A Time-Scale Variational Approach to Inflation, Unemployment and Social Loss

description: Both inflation and unemployment inflict social losses. When a tradeoff exists between the two, what would be the best combination of inflation and unemployment? A well known approach in economics to address this question consists to write the social loss as a function of the rate of inflation $p$ and the rate of unemployment $u$, with different weights, and then, using known relations between $p$, $u$, and the expected rate of inflation $π$, to rewrite the social loss function as a function of $π$. The answer is achieved by applying the theory of the calculus of variations in order to find an optimal path $π$ that minimizes the total social loss over a given time interval. Economists dealing with this question use a continuous or a discrete variational problem. Here we propose to use a time-scale model, unifying available results in the literature. Moreover, the new formalism allow us to obtain new insights to the classical models when applied to real data of inflation and unemployment.

description: We use the notion of polar duality from convex geometry and the theory of Lagrangian planes from symplectic geometry to construct a fiber bundle over ellipsoids that can be viewed as a quantum-mechanical substitute for the classical symplectic phase space. The total space of this fiber bundle consists of geometric quantum states, products of convex bodies carried by Lagrangian planes by their polar duals with respect to a second transversal Lagrangian plane.. Using the theory of the John ellipsoid we relate these geometric quantum states to the notion of "quantum blobs" introduced in previous work; quantum blobs are the smallest symplectic invariant regions of the phase space compatible with the uncertainty principle. We show that the set of equivalence classes of unitarily related geometric quantum states is in a one-to-one correspondence with the set of all Gaussian wavepackets.

description: We show that the new measurement of the effective number of neutrinos Neff by the Planck satellite can be used to set a robust lower bound on the mass of cold thermal dark matter of O(MeV). Our limit applies if the dark matter remains in thermal equilibrium by coupling to electrons and photons or through interactions with neutrinos, and applies regardless of whether the dark matter annihilation cross-section is s-wave or p-wave. To illustrate our bounds we apply them to a model of a supersymmetric neutralino annihilating to neutrinos, via a light mixed left-right handed sneutrino mediator. While this scenario was not constrained by previous data, the Planck limits on Neff allow us to set a lower bound on the neutralino dark matter mass of 3.5 MeV.
