description: We demonstrate a quantum error correction scheme that protects against accidental measurement, using an encoding where the logical state of a single qubit is encoded into two physical qubits using a non-deterministic photonic CNOT gate. For the single qubit input states |0>, |1>, |0>+|1>, |0>-|1>, |0>+i|1>, and |0>-i|1> our encoder produces the appropriate 2-qubit encoded state with an average fidelity of 0.88(3) and the single qubit decoded states have an average fidelity of 0.93(5) with the original state. We are able to decode the 2-qubit state (up to a bit flip) by performing a measurement on one of the qubits in the logical basis; we find that the 64 1-qubit decoded states arising from 16 real and imaginary single qubit superposition inputs have an average fidelity of 0.96(3).

description: The purpose of this article was to discuss cost parameters for the milk collection freight, based in the theoretical principles of scale economies and distance. Such study is justified for the difficulties to measure the parameters which might help in the management of the fleets, relating to the case of milk transportation. The costs related to different kinds of vehicle were estimated, through cost spreadsheets developed by the pattern support system and also the parameters of fleet efficiency related to Economies of scale, and distance for transportation. It was evidenced economy in favor of the vehicles with major transport capacity; such evidences could direct the table negotiations of freights, signaling for the preference for the use of this type of vehicle of greater capacity and better performance, according to evaluated parameters.

description: SLHA file for (scalar top, scalar tau) mass point (561,450) GeV
description: A search for direct pair production of the supersymmetric partner of the top quark, decaying via a scalar tau to a nearly massless gravitino, has been performed using 20 fb$^{-1}$ of proton-proton collision data at $\sqrt{s}=8$ TeV. The data were collected by the ATLAS experiment at the LHC in 2012. Scalar top candidates are searched for in events with either two hadronically decaying tau leptons, one hadronically decaying tau and one light lepton, or two light leptons. No significant excess over the Standard Model expectation is found. Exclusion limits at 95% confidence level are set as a function of the scalar top and scalar tau masses. Depending on the scalar tau mass, ranging from the 87 GeV LEP limit to the scalar top mass, lower limits between 490 GeV and 650 GeV are placed on the scalar top mass within the model considered.

description: It is shown that the neutrino mass matrices in the flavour basis yielding a vanishing $U_{e3}$ are characterized by invariance under a class of $Z_2$ symmetries. A specific $Z_2$ in this class also leads to a maximal atmospheric mixing angle $θ_{23}$. The breaking of that $Z_2$ can be parameterized by two dimensionless quantities, $\e$ and $\e'$; the effects of $\e, \e' \neq 0$ are studied perturbatively and numerically. The induced value of $\ue3$ strongly depends on the neutrino mass hierarchy. We find that $\ue3$ is less than 0.07 for a normal mass hierarchy, even when $\e, \e' \sim 30 %$. For an inverted mass hierarchy $\ue3$ tends to be around 0.1 but can be as large as 0.17. In the case of quasi-degenerate neutrinos, $\ue3$ could be close to its experimental upper bound 0.2. In contrast, $| \cos{2θ_{23}} |$ can always reach its experimental upper bound 0.28. We propose a specific model, based on electroweak radiative corrections in the MSSM, for $\e$ and $\e'$. In that model, both $\ue3$ and $| \cos{2 θ_{23}} |$, could be close to their respective experimental upper bounds if neutrinos are quasi-degenerate.

description: Deep neural networks (DNNs) have been recently found popular for image captioning problems in remote sensing (RS). Existing DNN based approaches rely on the availability of a training set made up of a high number of RS images with their captions. However, captions of training images may contain redundant information (they can be repetitive or semantically similar to each other), resulting in information deficiency while learning a mapping from the image domain to the language domain. To overcome this limitation, in this paper, we present a novel Summarization Driven Remote Sensing Image Captioning (SD-RSIC) approach. The proposed approach consists of three main steps. The first step obtains the standard image captions by jointly exploiting convolutional neural networks (CNNs) with long short-term memory (LSTM) networks. The second step, unlike the existing RS image captioning methods, summarizes the ground-truth captions of each training image into a single caption by exploiting sequence to sequence neural networks and eliminates the redundancy present in the training set. The third step automatically defines the adaptive weights associated to each RS image to combine the standard captions with the summarized captions based on the semantic content of the image. This is achieved by a novel adaptive weighting strategy defined in the context of LSTM networks. Experimental results obtained on the RSCID, UCM-Captions and Sydney-Captions datasets show the effectiveness of the proposed approach compared to the state-of-the-art RS image captioning approaches. The code of the proposed approach is publicly available at https://gitlab.tubit.tu-berlin.de/rsim/SD-RSIC.

description: This study examined the economics of sweet potato production in Kwara State of Nigeria. The study was conducted within the framework of the rural farming households who constitute the backbone of the Nigerian agricultural sector, producing about 80 per cent of the total national agricultural output with the cutlass-hoe technology and under rain fed conditions. Using cross-sectional data collected from 152 randomly selected sweet potato farmers from Oyun and Offa Local Government Areas of Kwara State, the study measured the profitability of and the technical efficiency of sweet potato production in the area. Primary data were collected from the sampled farming households using a structured interview schedule. Descriptive and inferential statistics was used to analyze the data. A Cobb Douglas production function was further employed to analyze the data using the maximum likelihood estimation (MLE) procedure to derive the stochastic frontier production function. The study revealed that the typical sweet potato farmer in the area is a male of about 52 years, with up to 23 years experience in farming and without formal education. The farmers have an average farm size of 1.05ha. The study revealed a positive gross margin of N15,29315 ha-1. Farm size, planting material and labour inputs were significant variables having positive impact on sweet potato output. Fertilizer was found to have negative effect on output. The study further revealed a mean technical efficiency of 0.473. For better efficiency, the land area cultivated, the educational status of the farmers, accessibility to credit facility, and development of the rural areas as well as farmers’ contact with the extension agents are some of the key issues to address.
Dimensions of Competitiveness: Lessons from the Danish Pork Industry

description: Conventional evaluations of industry competitiveness tend to focus on a narrow range of production cost variables. Using these criteria, we would expect industries such as the Danish pork industry to be uncompetitive relative to the pork industries of Canada and the United States, given relatively high input costs and legislative limits on farm size for environmental reasons. Yet Denmark accounts for 25 to 30 percent of global pork exports. To explain this apparent paradox, a broader conception of what is meant by “competitiveness” is required. Included in this broader perspective are the effects of transaction costs, vertical supply chain linkages, the policy environment, and competitive pressures, along with traditional measures of production costs and efficiencies. The Danish pork industry provides a useful case study. Recent merger activity within the Danish pork sector has the potential to alter its relative competitiveness.

description: Computability logic (CL) is a systematic formal theory of computational tasks and resources, which, in a sense, can be seen as a semantics-based alternative to (the syntactically introduced) linear logic. With its expressive and flexible language, where formulas represent computational problems and "truth" is understood as algorithmic solvability, CL potentially offers a comprehensive logical basis for constructive applied theories and computing systems inherently requiring constructive and computationally meaningful underlying logics. Among the best known constructivistic logics is Heyting's intuitionistic calculus INT, whose language can be seen as a special fragment of that of CL. The constructivistic philosophy of INT, however, has never really found an intuitively convincing and mathematically strict semantical justification. CL has good claims to provide such a justification and hence a materialization of Kolmogorov's known thesis "INT = logic of problems". The present paper contains a soundness proof for INT with respect to the CL semantics. A comprehensive online source on CL is available at http://www.cis.upenn.edu/~giorgi/cl.html

description: Adiabatic measurements, followed by feedback and erasure protocols, have often been considered as a model to embody Maxwell's Demon paradox and to study the interplay between thermodynamics and information processing. Such studies have led to the conclusion, now widely accepted in the community, that Maxwell's Demon and the second law of thermodynamics can peacefully coexist because any gain provided by the demon must be offset by the cost of performing the measurement and resetting the demon's memory to its initial state. Statements of this kind are collectively referred to as second laws of information thermodynamics and have recently been extended to include quantum theoretical scenarios. However, previous studies in this direction have made several assumptions, particularly about the feedback process and the demon's memory readout, and thus arrived at statements that are not universally applicable and whose range of validity is not clear. In this work, we fill this gap by precisely characterizing the full range of quantum feedback control and erasure protocols that are overall consistent with the second law of thermodynamics. This leads us to conclude that the second law of information thermodynamics is indeed universal: it must hold for any quantum feedback control and erasure protocol, regardless of the measurement process involved, as long as the protocol is overall compatible with thermodynamics. Our comprehensive analysis not only encompasses new scenarios but also retrieves previous ones, doing so with fewer assumptions. This simplification contributes to a clearer understanding of the theory.

A new form of QS calculus based on an inductive *-algebraic structure in an indefinite space is developed and a nonadaptive generalization of the QS Ito formula for its representation in Fock space is derived. The problem of solution of general QS evolution equations in a Hilbert space is solved in terms of the constructed operator representation of chronological products, defined in the indefinite space, and the unitary and *-homomorphism property respectively for operators and maps of these solutions, corresponding to the pseudounitary and *-homomorphism property of the QS integrable generators, is proved.

description: The introduction of AI-based systems in healthcare has transformed various aspects of patient care, including medication management, clinical decision support, diagnostic assistance, patient monitoring, and infection control. This study presents the results of AI integration in these domains, highlighting the significant improvements in healthcare delivery and patient outcomes. In medication management, AI-driven systems have revolutionized processes such as medication reconciliation, dosage calculation, and drug interaction checks, leading to a substantial reduction in medication errors. Similarly, in clinical decision support, AI algorithms have provided real-time guidance to nurses, resulting in enhanced clinical decision-making and adverse event prevention. Diagnostic support systems powered by AI have improved diagnostic accuracy and efficiency, enabling early detection and treatment of medical conditions. AI-based patient monitoring systems continuously track vital signs and physiological parameters, allowing for early detection of patient deterioration and timely interventions. Furthermore, AI-powered infection control systems have played a crucial role in identifying and preventing healthcare-associated infections, contributing to improved patient safety. Based on the findings, recommendations for the integration and optimization of AI technologies in healthcare practice are proposed. These recommendations include the development of standardized protocols for AI implementation, ongoing training and education for healthcare professionals, and investment in robust data infrastructure and interoperability. Additionally, collaboration between healthcare providers, technology developers, and regulatory bodies is essential to ensure the ethical and responsible use of AI in healthcare.

Risk and Uncertainty

description: Feed peas are relatively high in energy and protein and compete with other feed grains and protein crops in the livestock feed market. Prior to 1995, a futures market did not exist for this commodity. To meet industry demand for a hedging and forward pricing mechanism, the Winnipeg Commodity Exchange (WCE) introduced a feed pea futures contract in November 1995. This study investigates the Canadian feed pea market prior to and during the startup of this first WCE feed pea futures contract. In particular, the study explores whether the WCE could have conducted an analysis using then-existing data that would have assisted in the design and establishment of the futures contract. The primary research objective was to determine the ability of the Winnipeg feed pea futures contract, as first specified in November 1995, to provide a price discovery mechanism and to reduce pricing risk. Historical feed pea price data and key concepts related to successful futures contracts were evaluated. Feed pea price data available to the WCE before and just after introduction of the futures contract were analyzed to compare pea prices in Canada to pea prices in Europe. This analysis evaluated the potential for success of the WCE feed pea futures contract. The analysis included (1) measuring absolute and relative price risk in feed peas and other North American crops; (2) comparing the basis (costs to move the product between one market and another) of feed peas to the basis for other crops traded between North America and Europe; (3) carrying out Granger causality tests to compare price determination in North America and Europe; and (4) conducting cointegration tests to assess the relationship between the Canadian and European feed pea markets. We argue that this is the analysis the WCE could have conducted to assist in designing and establishing the 1995 feed pea futures contract.

description: The internal structure of a composite fermion is investigated for a two dimensional parabolic quantum dot containing three electrons. A Yukawa screened Coulomb interaction is assumed, which allows us to discuss the evolution of the electron-vortex correlations from the Coulomb interaction limit to the contact potential limit. The vortex structure approaches the Laughlin limit non-monotonically through the formation of intermediate composite fermions in which a flip of the spatial orientation of the vortices with respect to the position of the electrons is observed. Only when we limit ourselves to the lowest Landau level (LLL) approximation the flip appears through the formation of an intermediate giant vortex at specific values of the screening length. Beyond the LLL approximation antivortices appear in the internal structure of the intermediate composite fermions which prevent the nucleation of giant vortices. We also studied the system of five electrons and show that the mechanism of the flip of the vortex orientation found for three-electron system is reproduced for higher number of electrons.

description: We consider a natural generalization of trinification to theories with 3N SU(3) gauge groups. These theories have a simple moose representation and a gauge boson spectrum that can be interpreted via the deconstruction of a 5D theory with unified symmetry broken on a boundary. Although the matter and Higgs sectors of the theory have no simple extra-dimensional analog, gauge unification retains features characteristic of the 5D theory. We determine possible assignments of the matter and Higgs fields to unified multiplets and present theories that are viable alternatives to minimal trinified GUTs.

description: Symmetry, a fundamental concept to understand our environment, often oversimplifies reality from a mathematical perspective. Humans are a prime example, deviating from perfect symmetry in terms of appearance and cognitive biases (e.g. having a dominant hand). Nevertheless, our brain can easily overcome these imperfections and efficiently adapt to symmetrical tasks. The driving motivation behind this work lies in capturing this ability through reinforcement learning. To this end, we introduce Adaptive Symmetry Learning (ASL), a model-minimization actor-critic extension that addresses incomplete or inexact symmetry descriptions by adapting itself during the learning process. ASL consists of a symmetry fitting component and a modular loss function that enforces a common symmetric relation across all states while adapting to the learned policy. The performance of ASL is compared to existing symmetry-enhanced methods in a case study involving a four-legged ant model for multidirectional locomotion tasks. The results show that ASL can recover from large perturbations and generalize knowledge to hidden symmetric states. It achieves comparable or better performance than alternative methods in most scenarios, making it a valuable approach for leveraging model symmetry while compensating for inherent perturbations.

description: Using computer simulation, we have studied the random sequential adsorption of stiff linear $k$-mers onto a square lattice. Each such particle occupies $k$ adjacent lattice sites. During deposition, the two mutually perpendicular orientations of the particles are equiprobable, hence, a macroscopically isotropic monolayer is formed. However, this monolayer is locally anisotropic, since the deposited particles tend to form domains of particles with the same orientation. Using the "excluded area" concept, we have classified lattice sites into several types and examined how the fraction of each type of lattice site varies as the number of deposited particles increases. The behaviors of these quantities have allowed us to identify the following stages of domain formation (i) the emergence of domain seeds; (ii) the filling of domains; (iii) densification of the domains.

Our results at low temperature are consistent with the experimental findings by Nagai {\em et al.} [Phys. Rev. B {\bf 68}, 081202 (R) (2003)]. The kinetics of the e-h system in diamonds at high temperature under both low and high excitations is also predicted.

description: In this article, we introduce a generalization of one-way superdense coding to two-way communication protocols for transmitting classical bits by using entangled quantum pairs. The proposed protocol jointly addresses the provision of entangled pairs and superdense coding, introducing an integrated approach for managing entanglement within the communication protocol. To assess the performance of the proposed protocol, we consider its data rate and resource usage, and we analyze this both in an ideal setting with no decoherence and in a more realistic setting where decoherence must be taken into account. In the ideal case, the proposal offers a 50% increase in both data rate and resource usage efficiency compared to conventional protocols. Even when decoherence is taken into consideration, the quantum protocol performs better as long as the decoherence time is not extremely short. Finally, we present the results of implementing the protocol in a computer simulation based on the NetSquid framework. We compare the simulation results with the theoretical values.

description: In solid mechanics, Data-driven approaches are widely considered as the new paradigm that can overcome the classic problems of constitutive models such as limiting hypothesis, complexity, and high dependence on training data. However, implementation of machine-learned approaches in material modeling has been modest due to the high-dimensionality of the data space, significant size of missing data, and limited convergence. This work proposes a framework to hire concepts from polymer science, statistical physics, and continuum mechanics to provide super-constrained machine-learning techniques of reduced-order to overcome many of the existing difficulties. Using a sequential order-reduction, we have simplified the 3D stress-strain tensor mapping problem into a limited number of super-constrained 1D mapping problems. Next, we introduce an assembly of multiple replicated Neural Network agents to systematically classify those mapping problems into a few categories, all of which are replications of a few distinct agent types. By capturing all loading modes through a simplified set of disperse experimental data, the proposed hybrid assembly of agents provides a new generation of machine learned approaches that simply outperforms most constitutive laws in training data volume, training speed, and accuracy even in complicated loading scenarios. Also, it avoids low interpretability of conventional AI-based models.

description: A topological insulator is a quantum material which possesses conducting surfaces and an insulating bulk. Despite extensive researches on the properties of Dirac surface states, the characteristics of bulk states have remained largely unexplored. Here we report the observation of spinor-dominated magnetoresistance anomalies in the topological insulator $β$-Ag$_2$Se, induced by a magnetic-field-driven band topological phase transition. These anomalies are caused by intrinsic orthogonality in the wave-function spinors of the last Landau bands of the bulk states, in which backscattering is strictly forbidden during a band topological phase transition. This new type of longitudinal magnetoresistance, purely controlled by the wave-function spinors of the last Landau bands, highlights a unique signature of electrical transport around the band topological phase transition. With further reducing the quantum limit and gap size in $β$-Ag$_2$Se, our results may also suggest possible device applications based on this spinor-dominated mechanism and signify a rare case where topology enters the realm of magnetoresistance control.

description: Biological motors are marvels of nature that inspire creation of their synthetic counterparts with comparable nanoscale dimensions, high efficiency and diverse functions. Molecular motors have been synthesized, but obtaining nanomotors through self-assembly remains challenging. Here we describe a self-assembled colloidal motor with a repetitive light-driven rotation of transparent micro-particles immersed in a liquid crystal and powered by a continuous exposure to unstructured ~1 nW light. A monolayer of azobenzene molecules defines how the liquid crystal's optical axis mechanically couples to the particle's surface, as well as how they jointly rotate as the light's polarization changes. The rotating particle twists the liquid crystal, which changes polarization of traversing light. The resulting feedback mechanism yields a continuous opto-mechanical cycle and drives the unidirectional particle spinning, with handedness and frequency robustly controlled by polarization and intensity of light. Our findings may lead to opto-mechanical devices and colloidal machines compatible with liquid crystal display technology.

description: This research examines collaboration between ESL teachers and core-subject teachers in an English Medium European International School following a graduated supported immersion program for Limited English Proficient (LEP) students. The research methodology includes both qualitative and quantitative methods. The study describes collaboration between ESL and core-subject teachers and analyzes their perspectives on different aspects of the collaborative process. It seeks to increase our understanding of the factors which facilitate collaboration, with particular reference to what makes it a more positive and effective experience for teachers. Additionally, the viewpoints of two administrators are examined with regard to the role of the administration in facilitating collaboration between teachers. This study does not seek to determine or analyze the outcomes of collaboration in terms of student achievement. An examination of the data revealed that teachers collaborate to varying degrees, for different reasons and have a preference for different communication modes. Key issues identified by teachers included: the importance of a strong relationship with collaborating colleagues, time, administrative support, and the role of LEP students in the collaboration process. Additionally, it was found that teachers' perspectives on collaboration were linked with their perspective on the ESL program in place. Teachers also offered suggestions for how they felt collaboration could or should be improved. Perspectives shared by the administrators revealed that they value supporting collaboration between teachers, but are faced with constraints that affect the degree to which collaboration can be facilitated. The study has a number of implications for practice. Preliminary conclusions are drawn based on the data collected and suggestions are made for improving collaboration in terms of factors that facilitate an effective and satisfying collaborative process. These include re-prioritizing who collaborates with whom, the scheduling of common planning time, re-conceptualizing the issue of prep time, and effective support of collaboration. The study concludes with suggestions for further research in the area of collaboration between ESL and core-subject teachers.

description: Inducing farmers to adopt alternative, more environmentally friendly production practices has been attempted in a variety of ways ranging from moral suasion to direct regulation to economic instruments. Among the most common instruments are voluntary cost-share programs that involve taxpayers sharing in the cost of production practices that generate fewer pollutants. These programs increase the attractiveness of alternative practices to farmers because they either compensate the farmer for any loss in profits or they offset the capital costs of adopting the new technology. Voluntary cost-share programs are a common policy tool because of their political viability, but their effectiveness has been limited largely due to the blanket approach used to distribute funds (Weersink et al., 1998). Since such programs continue to be a popular policy tool, as evidenced by the Environmental Quality Incentive Program (EQIP) in the United States and the National Heritage Trust in Australia, regulators need to know how to improve their effectiveness. This paper examines whether voluntary cost-share programs can succeed in achieving environmental objectives efficiently. The paper begins by developing a conceptual model of atypical cost-share program in which the regulator subsidizes the cost incurred for a set of pre-approved abatement practices. The paper then examines the cost-share program — the Rural Water Quality Program (RWQP) implemented in the Grand River Watershed by the Regional Municipality of Waterloo, Ontario.

description: La 21e édition du festival de Biarritz consacré aux cinémas d’Amérique latine (24 septembre-30septembre 2012) a choisi de faire connaître la Colombie aux spectateurs. Ceci permet de laisser la place à un cinéma plus méconnu par rapport aux cinémas argentin, brésilien ou mexicain. Son président Jean-Marie Dupont signale combien l’Amérique latine est en pleine effervescence et le cinéma est là pour en témoigner. Par ailleurs le Festival était placé sous le signe des cultures mayas donnant lieu à diverses manifestations culturelles afin de mieux connaître en particulier leur cosmovision. Il apparaît que ce choix n’avait bien évidemment rien à voir avec la fin du calendrier maya, assimilée à la fin du monde. Diverses manifestations et rencontres (Abilio Estévez, Hernán Rivera Letelier, Santiago Gamboa, Laura Alcoba) ainsi qu’un hommage à Carlos Fuentes (disparu en mai 2012) et même un salon du livre latino-américain se sont déroulés permettant de nombreux échanges. Le choix des films reflète fidèlement l’état des sociétés d’Amérique latine où sont prises en compte non seulement l’histoire contemporaine (référendum au Chili sous Pinochet : No, l’histoire de Clara Rojas otage des FARC : Operación E, l’invasion de zombies à Cuba (« soutenus » par les Américains) : Juan de los muertos) mais aussi l’histoire individuelle de personnages représentatifs de ces sociétés mais par ailleurs proches de nos sociétés par les thèmes traités : la vie des jeunes, la vieillesse et la pauvreté. Voici le récapitulatif des prix attribués lors du 21e festival.

description: We present a novel inference scheme, self-speculative decoding, for accelerating Large Language Models (LLMs) without the need for an auxiliary model. This approach is characterized by a two-stage process: drafting and verification. The drafting stage generates draft tokens at a slightly lower quality but more quickly, which is achieved by selectively skipping certain intermediate layers during drafting. Subsequently, the verification stage employs the original LLM to validate those draft output tokens in one forward pass. This process ensures the final output remains identical to that produced by the unaltered LLM. Moreover, the proposed method requires no additional neural network training and no extra memory footprint, making it a plug-and-play and cost-effective solution for inference acceleration. Benchmarks with LLaMA-2 and its variants demonstrated a speedup up to 1.99$\times$.

description: We discuss the very different roles of the valence-quark and the sea-quark residual masses ($m_{res}^v$ and $m_{res}^s$) in dynamical domain-wall fermions simulations. Focusing on matrix elements of the effective weak hamiltonian containing a power divergence, we find that $m_{res}^v$ can be a source of a much bigger systematic error. To keep all systematic errors due to residual masses at the 1% level, we estimate that one needs $a m_{res}^s \le 10^{-3}$ and $a m_{res}^v \le 10^{-5}$, at a lattice spacing $a\sim 0.1$ fm. The practical implications are that (1) optimal use of computer resources calls for a mixed scheme with different domain-wall fermion actions for the valence and sea quarks; (2) better domain-wall fermion actions are needed for both the sea and the valence sectors.

description: Recent observations of quark-gluon plasma (QGP) like signatures in high multiplicity proton-proton (pp) collisions, have compelled the heavy-ion physics community to re-examine small collision systems for proper baseline studies. Event-shape-based studies in pp collisions have succeeded to a certain extent in identifying the rare events mimicking such heavy-ion-like behaviour. In this study, we incorporate PYTHIA8 and AMPT to study radial flow-like signatures in pp collisions at $\sqrt{s} = 13$ TeV as a function of transverse spherocity and pseudorapidity. The selection of softer events possibly carrying heavy-ion-like features is performed using the transverse spherocity event-shape observable. As the particle production mechanism in midrapidity differs greatly from the forward rapidity, a pseudorapidity-dependent study is meaningful. Keeping ALICE 3 upgrades at the LHC in mind, this study aims to demonstrate the transverse spherocity and pseudorapidity dependence of the mean transverse momentum, particle ratios, and kinetic freezeout parameters in pp collisions at $\sqrt{s}$ = 13 TeV using PYTHIA8. We observe that the isotropic events show enhanced radial-flow effects in all multiplicity classes, however, the jetty events show signatures of the radial flow-like effects only in high-multiplicity events. For the first time, we show the transverse spherocity and pseudorapidity dependence of partonic modification factor in pp collisions, which clearly shows that by choosing transverse spherocity, one can directly probe the radial flow-like effects in pp collisions at the LHC.

description: We propose an experimental protocol to realize discrete variable quantum teleportation using optomechanical devices. The photonic polarization superposition state of a single photon is teleported to a phononic superposition of two micromechanical oscillators by means of photon/phonon entanglement generation and optical Bell state measurement using two-photon interference. Verification of the protocol is performed by coherent state transfer between the mechanical devices and light. Simulations show the feasibility of the proposed scheme at millikelvin temperatures using state-of-the-art gigahertz optomechanical devices.
