description: We study the two and four dimensional Nishimori multicritical point via high temperature expansions for the $\pm J$ distribution, random-bond, Ising model. In $2d$ we estimate the the critical exponents along the Nishimori line to be $γ=2.37\pm 0.05$, $ν=1.32\pm 0.08$. These, and earlier $3d$ estimates $γ=1.80\pm 0.15$, $ν=0.85\pm 0.08$ are remarkably close to the critical exponents for percolation, which are known to be $γ=43/18$, $ν=4/3$ in $d=2$ and $γ=1.805\pm0.02$ and $ν=0.875\pm 0.008$ in $d=3$. However, the estimated $4d$ Nishimori exponents $γ=1.80\pm 0.15$, $ν=1.0\pm 0.1$, are quite distinct from the $4d$ percolation results $γ=1.435\pm 0.015$, $ν=0.678\pm 0.05$.

Multi-User Entanglement Distribution in Quantum Networks Using Multipath Routing

description: Quantum networks facilitate numerous applications such as secure communication and distributed quantum computation by performing entanglement distribution. Multi-user quantum applications where quantum information is shared between multiple users require access to a shared multipartite state between the users. We consider the problem of designing protocols for distributing such states, at an increased entanglement rate.
 We propose three protocols that increase the entanglement rate of multi-user applications by leveraging multipath routing. The protocols are evaluated on quantum networks with NISQ constraints, including limited quantum memories and probabilistic entanglement generation. Monte Carlo simulation results show that the developed protocols achieve an exponential speedup of entanglement rate compared to single-path routing techniques, with a maximum speedup of four orders of magnitude for the cases studied. The speedup was also found to improve for larger sets of users. When the protocols were tested in scaled-down real-world topologies, it was found that topology can have a significant effect on the achievable entanglement rates, with one order of magnitude difference between topologies. Finally, we find that the benefits of multipath routing are a maximum for short quantum memory decoherence times, and intermediate values of entanglement generation probability. Hence the protocols developed can benefit NISQ quantum network control and design.

description: Superscaling in electron scattering from nuclei is re-examined paying special attention to the definition of the averaged single-nucleon responses. The validity of the extrapolation of nucleon responses in the Fermi gas has been examined, which previously lacked a theoretical foundation. To address this issue, we introduce new averaged responses with a momentum distribution smeared around the Fermi surface, allowing for momenta above the Fermi momentum. This approach solves the problem of negativity in the extrapolation away from the scaling region and, at the same time, validates its use in the scaling analysis. This work has important implications for the interpretation of scaling data and contributes to the development of a more complete understanding of the scaling approach.

description: Orbital current has emerged over the past years as one of the key novel concepts in magnetotransport. Here, we demonstrate that laser pulses can be used to generate large and robust non-relativistic orbital currents in systems where the inversion symmetry is broken by the orbital Rashba effect. By referring to model and first principles tools, we demonstrate that orbital Rashba effect, accompanied by crystal field splitting, can mediate robust orbital photocurrents without a need for spin-orbit interaction even in metallic systems. We show that such non-relativistic orbital photocurrents are translated into derivative photocurrents of spin when relativistic effects are taken into account. We thus promote orbital photocurrents as a promising platform for optical generation of currents of angular momentum, and discuss their possible applications.

description: Constraining CP-violating interactions in effective field theory (EFT) of dimension six faces two challenges. Firstly, degeneracies in the multi-dimensional space of Wilson coefficients have to be lifted. Secondly, quadratic contributions of CP-odd dimension six operators are difficult to disentangle from squared contributions of CP-even dimension six operators and from linear contributions of dimension eight operators. Both of these problems are present when new sources of CP-violation are present in the interactions between the Higgs boson and heavy strongly-interacting fermions. We show that degeneracies in the Wilson coefficients can be removed by combining measurements of Higgs-plus-two-jet production via gluon fusion with measurements of top-pair associated Higgs production. In addition, we demonstrate that the sensitivity of the analysis can be improved by exploiting the top-quark threshold in the gluon fusion process. Finally, we substantiate a perturbative argument about the validity of EFT by comparing the quadratic and linear contributions from CP-odd dimension six operators and use this to show explicitly that high statistics measurements at future colliders enable the extraction of perturbatively robust constraints on the associated Wilson coefficients.

description: By combining high-sensitivity LOFAR 150MHz, uGMRT 400MHz and 1,250MHz, GMRT 610MHz, and VLA 5GHz data in the ELAIS-N1 field, we study the radio spectral properties of radio-detected star-forming galaxies (SFGs) at observer-frame frequencies of 150-5,000MHz. We select ~3,500 SFGs that have both LOFAR 150MHz and GMRT 610MHz detections, and obtain a median two-point spectral index of $α_{150}^{610}=-0.51\pm0.01$. The photometric redshift of these SFGs spans $z=0.01-6.21$. We also measure the two-point radio spectral indices at 150-400-610-1,250MHz and 150-610-5,000MHz respectively for the GMRT 610-MHz-detected SFGs, and find that, on average, the radio spectrum of SFGs is flatter at low frequency than at high frequency. At observer-frame 150-5,000MHz, we find that the radio spectrum slightly steepens with increasing stellar mass. However, we only find that the radio spectrum flattens with increasing optical depth at $V$-band at $ν<1$GHz. We suggest that spectral ageing due to the energy loss of CR electrons and thermal free-free absorption could be among the possible main physical mechanisms that drive the above two correlations respectively. In addition, both of these mechanisms could physically explain why the radio spectrum is flatter at low frequency than at high frequency.

description: The leading soft photon theorem implies that four-dimensional scattering amplitudes are controlled by a two-dimensional (2D) $U(1)$ Kac-Moody symmetry that acts on the celestial sphere at null infinity ($\mathcal{I}$). This celestial $U(1)$ current is realized by components of the electromagnetic vector potential on the boundaries of $\mathcal{I}$. Here, we develop a parallel story for Low's subleading soft photon theorem. It gives rise to a second celestial current, which is realized by vector potential components that are subleading in the large radius expansion about the boundaries of $\mathcal{I}$. The subleading soft photon theorem is reexpressed as a celestial Ward identity for this second current, which involves novel shifts by one unit in the conformal dimension of charged operators.

description: The British Empire and imperialism are crucial parts of Jane Austen’s novel Persuasion. To investigate how the novel represents and purports imperialism, this paper combines a structuralist with a postcolonial approach and applies Said’s method of ‘contrapuntal reading.’ In addition, the approach of cultural materialism is relevant for the novel’s representation of class. My argumentation first consists of an analysis of the character constellation, in particular the opposition of gentry and naval characters, and narrative situation before turning to the novel’s marriage plot. I argue that Austen’s realist novel Persuasion legitimizes British imperialism due to its use of narrative techniques, plot, and character constellation. The narrative does not question the represented empire which functions as an opportunity for wealth and social mobility for the characters. The marriage plot, in which the female protagonist chooses a naval captain over her cousin from the landed gentry, further corroborates the novel’s support of the British Empire and demonstrates the increasing importance of the navy as well as the professional classes for England at the beginning of the nineteenth century.

description: This article examines gender roles and relations in the young adult novel Twilight (2005) by Stephenie Meyer, utilizing the structuralist anthropological theory of the exchange of women as the basis of kinship introduced by Claude Lévi-Strauss in 1949. This theory with regards to its implications about gender is first analyzed through a feminist perspective and then applied to Twilight, focusing primarily on the protagonist and her love interest. Finding that what is presented in the novel in terms of gender is almost analogous to the Lévi-Strauss’s ideas, this article argues that Meyer perpetuates archaic hetero-patriarchal gender relations in her work. This conclusion is given weight by framing it through Judith Butler’s theory about the repetitive nature of gender performance.

description: The task of finding a sparse signal decomposition in an overcomplete dictionary is made more complicated when the signal undergoes an unknown modulation (or convolution in the complementary Fourier domain). Such simultaneous sparse recovery and blind demodulation problems appear in many applications including medical imaging, super resolution, self-calibration, etc. In this paper, we consider a more general sparse recovery and blind demodulation problem in which each atom comprising the signal undergoes a distinct modulation process. Under the assumption that the modulating waveforms live in a known common subspace, we employ the lifting technique and recast this problem as the recovery of a column-wise sparse matrix from structured linear measurements. In this framework, we accomplish sparse recovery and blind demodulation simultaneously by minimizing the induced atomic norm, which in this problem corresponds to the block $\ell_1$ norm minimization. For perfect recovery in the noiseless case, we derive near optimal sample complexity bounds for Gaussian and random Fourier overcomplete dictionaries. We also provide bounds on recovering the column-wise sparse matrix in the noisy case. Numerical simulations illustrate and support our theoretical results.

The experiments reveal antiferromagnetic order and structural distortions characterized by tilts and rotations of the RuO$_6$-octahedra. There is strong evidence that the structural details of the isovalent samples tune the magnetic as well as the electronic behavior. In particular we observe for low Sr-concentration a metal insulator transition associated with a structural change and magnetic ordering.

description: Using the Indian Residential School (IRS) system as an example, this paper examines the internet as a decolonial site. To do so, I will draw on decolonial concepts as well as ideas from spatial theory. Through the analysis of Indigenous-led organizations and a Facebook group dedicated to the collective memory work of the IRS system, I argue that social media platforms can contribute to revitalize culture and foster communal bonds. Amongst others, digital storytelling, the establishment of common symbols, and the organization of joint actions in the offline world have emerged as digital strategies. These are complemented by collecting and sharing memories and educational materials online.

description: Quantum technologies have matured to the point that we can test fundamental quantum phenomena under extreme conditions. Specifically, entanglement, a cornerstone of modern quantum information theory, can be robustly produced and verified in various adverse environments. We take these tests further and implement a high-quality Bell experiment during a parabolic flight, transitioning from microgravity to hypergravity of 1.8 g while continuously observing Bell violation, with Bell-CHSH parameters between $S=-2.6202$ and $-2.7323$, an average of $\overline{S} = -2.680$, and average standard deviation of $\overline{ΔS} = 0.014$. This violation is unaffected both by uniform and non-uniform acceleration. This experiment demonstrates the stability of current quantum communication platforms for space-based applications and adds an important reference point for testing the interplay of non-inertial motion and quantum information.

The field of observation consists of all Italian university professors working in the life sciences, with scientific production examined over the period 2004-2008. The outcomes of the study lead to a recommendation against using indicators or evaluation methods that ignore the different authors' contributions to the research results.

description: Road traffic accident is one of the most common causes of deaths and injuries in the
 world. Ethiopia is among the leading countries in road traffic accident.
 The main aim of this study was to analyze the causes, severity and its countermeasures on
 the occurrence of road traffic accident focused on Addis Ababa roads, particularly Yeka
 Subcity. To meet the objective of the research, data on accident, road and traffic was
 collected from Addis Ababa Police Commission (AAPC) Traffic Office, Addis Ababa
 City Road Authority and field observation were conducted. Five years traffic accident
 victims" data for drivers, passengers, and pedestrians in their sex and age levels collected
 from AAPC between 2012/13 – 2016/17 years and analyzed by Statistical test (chi-square
 test) or Statistical Package for Social Sciences (SPSS). The road traffic accident in the
 Yeka Sub-City roads shows significant growth of the severity of the accidents from
 2014/15 - 2016/17 years. Most of these accidents occurred in market and residential areas,
 on road junction like midblock than the Y– junction and T – junctions. Besides, the
 highest accident rates were associated with double carriageways in straight and level road
 character. Eighteen road sections and five junctions were selected for black spot
 identification in Yeka Subcity. Quality control method was used to identify black spots
 and engineering countermeasures given by field observation to create a safer transport
 system in the Subcity. The study results indicated that road sections like Megenanga,
 Shola Mebrat, Zefmesh Grand mall, Wesen, Kara, Lambret, Meri and Tikur Abay, road
 were identified as Black spot areas, since they experienced the highest accident rates.
 Possible Engineering Countermeasures are use of traffic signs, user awareness campaigns,
 policy revisions enforcement and pavement modifications.

title: Hierarchical Clustering Techniques for Energy-efficient Algorithms in WSNs
Creators: name: Abushiba, W
Publisher: name: Liverpool John Moores University
Year: 2021

description: In Wireless Sensor Networks (WSNs) with large number of micro-sensor nodes, successfully receiving all the useful data with unnecessary loss of energy is a major challenge. WSNs are extremely important for many applications in civil and military domains. Despite their use in many successful applications, the sensor nodes are randomly deployed. This creates many operational and design challenges for WSNs that result in reduced network lifetime. This is because of limited energy available in the nodes and increased energy consumption with large sized networks. Therefore, giving attention to large-scale integration and energy consumption helps to improve the energy-efficiency of the sensor node. This plays a fundamental part in increasing the lifetime of WSNs. Despite the development of many WSNs protocols, such as the hierarchal routing protocols to address this issue, the energy-efficiency is still a limiting factor. This thesis, addresses the above-mentioned challenges by proposing a novel set of Energy-Adaptive Clustering Protocols (ECP) for energy-efficiency in WSNs. The proposed routing strategy takes on several approaches to improve energy efficiency in WSNs. This functional set of protocols are integrated with each other. The proposed novel solutions have been implemented using simulation and evaluated for a range of given metrics. The evaluations were based on the most critical metrics in WSNs, such as node density, throughput and network lifetime etc. For validation and evaluation purposes, the proposed techniques have been compared with existing solutions. It is found that our proposed protocols exhibit reduction in energy consumption over well-known protocols such as LEACH, DEEC, EE-LEACH and HT2HL. While the proposed technique network lifetime improved by average of 67 %, 17 %, 21 % and 8 % more than LEACH, DEEC, EE-LEACH and HT2HL protocols respectively. The ECPs were also evaluated to include mobile node detection. It is named Energy-Adaptive Clustering Protocols (d-ECP) for mobile node detection in WSNs. The proposed d-ECP has potential applications in scenarios where RFID type mobile nodes are used. For example wildlife monitoring, condition monitoring, industrial applications and IoT. Keywords: Wireless Sensor Network, Routing Protocols, Network Lifetime, Energy Consumption, Cluster-Head, Radio-frequency identification (RFID).

description: We investigate possibilities for detecting heavy Majorana neutrinos ($N$'s) in $e^+e^-$ at LEP200 and future Linear Colliders. We concentrate on the processes where the pairs of intermediate heavy $N$'s produce a clear signal of total lepton number violation ($e^+e^- \to NN \to W^+l^-W^+l^{\prime -}$). Such a signal is not possible if the heavy neutrinos are of Dirac nature. Our approach is general in the sense that the intermediate $N$'s can be either on shell or off shell. Discussion of the relative numerical importance of the $s$ and the $t+u$ channels of the $NN$ production is also included.

However, the effect of DIPs on infection spread is still unclear due to complicated stochastic effects and nonlinear spatial dynamics. In this work, we develop a model with a new hybrid method to study the spatial-temporal dynamics of viruses and DIPs co-infections within hosts. We present two different scenarios of virus production and compare the results from deterministic and stochastic models to demonstrate how the stochastic effect is involved in the spatial dynamics of virus transmission. We quantitatively study the spread features of the virus, including the formation and the speed of virus spread and the emergence of stochastic patchy patterns of virus distribution. Our simulations simultaneously capture observed spatial spread features in the experimental data, including the spread rate of the virus and its patchiness. The results demonstrate that DIPs can slow down the growth of virus particles and make the spread of the virus more patchy.

description: Purpose of Project: To improve the utilization of mindfulness exercises among undergraduate and graduate nursing students by using the Calm app for at least 10 minutes daily for four weeks. Methodology: A non-randomized, convenient sample was recruited via email at a nursing school in a public university in New Jersey. Before, during and after implementing the mindfulness intervention, participants were asked to complete an electronic Perceived Stress Scale (PSS) survey in order to measure its effectiveness. The participants were also asked how much time was spent using the Calm app daily and what feature of mindfulness was used from calming, deep breathing and meditation. Results: The findings from the study showed that there was statistical significance between improvements in the nursing students perceived stress scores before and after implementing the mindfulness intervention. Additionally, the more time students spent using minduflness daily, the lower their PSS scores. There was no statistical significance beween using the different features of mindfulness on the PSS scores. Implications for Practice: Significant results for nursing practice were obtained from this project. Using a mindfulness-based intervention for nursing students deemed beneficial in reducing stress levels. The stress of dealing with a highly demanding work and educational environment can lead to serious consequences. As a result, an intervention, such as mindfulness, is necessary to promote self-care, reduce burnout and as a result improve patient care outcomes.

description: We present the simplest non-abelian version of Seiberg-Witten theory: Quaternionic monopoles. These monopoles are associated with Spin^h(4)-structures on 4-manifolds and form finite-dimensional moduli spaces. On a Kahler surface the quaternionic monopole equations decouple and lead to the projective vortex equation for holomorphic pairs. This vortex equation comes from a moment map and gives rise to a new complex-geometric stability concept. The moduli spaces of quaternionic monopoles on Kahler surfaces have two closed subspaces, both naturally isomorphic with moduli spaces of canonically stable holomorphic pairs. These components intersect along Donaldsons instanton space and can be compactified with Seiberg-Witten moduli spaces. This should provide a link between the two corresponding theories. Notes: To appear in CMP The revised version contains more details concerning the Uhlenbeck compactfication of the moduli space of quaternionic monopoles, and possible applications are discussed. Attention ! Due to an ununderstandable mistake, the duke server had replaced all the symbols "=" by "=3D" in the tex-file of the revised version we sent on February, the 2-nd. The command "\def{\ad}" had also been damaged !

Double Higgs boson production at $e^+e^-$ colliders in the two-Higgs-doublet model

description: We study the double Higgs boson production processes $e^+e^- \to hh f\bar{f}$ ($f\neq t$) with $h$ being the 125 GeV Higgs boson in the two-Higgs-doublet model with a softly-broken $Z_2$ symmetry. The cross section can be significantly enhanced, typically a few hundreds percent, as compared to the standard model prediction due to resonant effects of heavy neutral Higgs bosons, which becomes important in the case without the alignment limit. We find a strong correlation between the enhancement factor of the cross section and the scaling factor of the $hf\bar{f}$ couplings under constraints from perturbative unitarity, vacuum stability and current experimental data at the LHC as well as the electroweak precision data.

description: The use of blockchains for automated and adversarial trading has become commonplace. However, due to the transparent nature of blockchains, an adversary is able to observe any pending, not-yet-mined transactions, along with their execution logic. This transparency further enables a new type of adversary, which copies and front-runs profitable pending transactions in real-time, yielding significant financial gains.
 Shedding light on such "copy-paste" malpractice, this paper introduces the Blockchain Imitation Game and proposes a generalized imitation attack methodology called Ape. Leveraging dynamic program analysis techniques, Ape supports the automatic synthesis of adversarial smart contracts. Over a timeframe of one year (1st of August, 2021 to 31st of July, 2022), Ape could have yielded 148.96M USD in profit on Ethereum, and 42.70M USD on BNB Smart Chain (BSC).
 Not only as a malicious attack, we further show the potential of transaction and contract imitation as a defensive strategy. Within one year, we find that Ape could have successfully imitated 13 and 22 known Decentralized Finance (DeFi) attacks on Ethereum and BSC, respectively. Our findings suggest that blockchain validators can imitate attacks in real-time to prevent intrusions in DeFi.
Transverse force on a quantized vortex in a superfluid

description: We have derived an exact expression for the total nondissipative transverse force acting on a quantized vortex moving in a uniform background. The derivation is valid for neutral boson or fermion superfluids, provided the order parameter is a complex scalar quantity. This force is determined by the one-particle density matrix far away from the vortex core, and is found to be the Magnus force proportional to the superfluid density. We conclude that contributions of the localized core states do not change this force.
Interplay between in-plane and flexural phonons in electronic transport of two-dimensional semiconductors

description: Out-of-plane vibrations are considered as the dominant factor limiting the intrinsic carrier mobility of suspended two-dimensional materials at low carrier concentrations. Anharmonic coupling between in-plane and flexural phonon modes is usually excluded from the consideration. Here we present a theory for the electron-phonon scattering, in which the anharmonic coupling between acoustic phonons is systematically taken into account. Our theory is applied to the typical group V two-dimensional semiconductors: hexagonal phosphorus, arsenic, and antimony. We find that the role of the flexural modes is essentially suppressed by their coupling with in-plane modes. At dopings lower than 10$^{12}$ cm$^{-2}$ the mobility reduction does not exceed 30\%, being almost independent of the concentration. Our findings suggest that compared to in-plane phonons, flexural phonons are considerably less important in the electronic transport of two-dimensional semiconductors, even at low carrier concentrations.

description: The phase change compound Ge$_2$Sb$_2$Te$_5$ (GST225) is exploited in advanced non-volatile electronic memories and in neuromorphic devices which both rely on a fast and reversible transition between the crystalline and amorphous phases induced by Joule heating. The crystallization kinetics of GST225 is a key functional feature for the operation of these devices. We report here on the development of a machine-learned interatomic potential for GST225 that allowed us to perform large scale molecular dynamics simulations (over 10000 atoms for over 100 ns) to uncover the details of the crystallization kinetics in a wide range of temperatures of interest for the programming of the devices. The potential is obtained by fitting with a deep neural network (NN) scheme a large quantum-mechanical database generated within Density Functional Theory. The availability of a highly efficient and yet highly accurate NN potential opens the possibility to simulate phase change materials at the length and time scales of the real devices.
Coherently Scattering Atoms from an Excited Bose-Einstein Condensate

description: We consider scattering atoms from a fully Bose-Einstein condensed gas. If we take these atoms to be identical to those in the Bose-Einstein condensate, this scattering process is to a large extent analogous to Andreev reflection from the interface between a superconducting and a normal metal. We determine the scattering wave function both in the absence and the presence of a vortex. Our results show a qualitative difference between these two cases that can be understood as due to an Aharonov-Bohm effect. It leads to the possibility to experimentally detect and study vortices in this way.
