Simple test for quantum channel capacity

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Basing on states and channels isomorphism we point out that semidefinite programming can be used as a quick test for nonzero one-way quantum channel capacity. This can be achieved by search of symmetric extensions of states isomorphic to a given quantum channel. With this method we provide examples of quantum channels that can lead to high entanglement transmission but still have zero one-way capacity, in particular, regions of symmetric extendibility for isotropic states in arbitrary dimensions are presented. Further we derive {\it a new entanglement parameter} based on (normalised) relative entropy distance to the set of states that have symmetric extensions and show explicitly the symmetric extension of isotropic states being the nearest to singlets in the set of symmetrically extendible states. The suitable regularisation of the parameter provides a new upper bound on one-way distillable entanglement.
description: 6 pages, no figures, RevTeX4. Signifficantly corrected version. Claim on continuity of channel capacities removed due to flaw in the corresponding proof. Changes and corrections performed in the part proposing a new upper bound on one-way distillable etanglement which happens to be not one-way entanglement monotone

description: We investigate theoretically, the character of electronic eigenstates and transmission properties of a one dimensional array of stubs with Cantor geometry. Within the framework of real space re-normalization group (RSRG) and transfer matrix methods we analyze the resonant transmission and extended wave-functions in a Cantor array of stubs, which lack translational order. Apart from resonant states with high transmittance we unravel a whole family of wave-functions supported by such an array clamped between two-infinite ordered leads, which have an extended character in the RSRG scheme, but, for such states the transmission coefficient across the lead-sample-lead structure decays following a power-law as the system grows in size. This feature is explained from renormalization group ideas and may lead to the possibility of trapping of electronic, optical or acoustic waves in such hierarchical geometries.

description: In this paper we have analyzed dynamics of milk prices in U.S. and performance of futures contracts as a tool to hedge price risk. Using spectral analysis, we find that lowering of support prices in early 1990s has induced 3-year business cycle with rising amplitude. We analyzed correlations of dairy prices and found current set of active dairy futures contracts to contain several redundant contracts. We utilized a new tool to visualize risk premium in futures prices to examine if Class III futures prices are unbiased predictors of announced USDA Class III price and we found no substantial evidence of bias. Employing partially overlapping time series model of Smith (2005) we analyzed seasonality and sources of volatility in futures prices. Model results indicate that futures prices volatility is higher in summer months, increases as time-to-maturity decreases up until eight weeks to maturity when settlement price starts to become increasingly predictable and uncertainty is quickly resolved. We name this decline in volatility in the last two trading months Inverse Samuelson effect. Further results reveal that common factor explains 50-60% of contract variance, with highest fraction of variance explained by common contract being 80+% about six to nine months prior to expiry when information regarding upper bound of dairy herd size at the time of maturity is revealed. Importance of common factor has itself pronounced seasonality that corresponds to seasonal cycles in dairy cow culling.

Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The gauge-invariance properties and singularity elimination of the modified perturbation theory for QCD introduced in previous works, are investigated. The construction of the modified free propagators is generalized to include the dependence on the gauge parameter $α$. Further, a functional proof of the independence of the theory under the changes of the quantum and classical gauges is given. The singularities appearing in the perturbative expansion are eliminated by properly combining dimensional regularization with the Nakanishi infrared regularization for the invariant functions in the operator quantization of the $α$-dependent gauge theory. First-order evaluations of various quantities are presented, illustrating the gauge invariance-properties.

description: We investigate the determinants of price for tractor auctions on eBay and tractors that are listed in the Farmers and Consumers Market Bulletin (FCMB) in Georgia. Surprisingly, seller reputation is not an important factor while engine hours and the presence of air conditioning appear to influence price on eBay auctions. On average prices for tractors that sold on eBay are not different than those on FCMB. The analysis also suggests that farmers may benefit from the use of online venues.

description: Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”. The result is resistance to insecticides, high control costs and unacceptable levels of chemical insecticides in the environment. Concerns about the environmental and human health effects from pesticide use thus need to be modeled in evaluation studies.
Edge-choosability and total-choosability of planar graphs with no adjacent 3-cycles
Creators: name: Cranston, Daniel W.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Combinatorics (math.CO)
subject: FOS: Mathematics

description: Let $G$ be a planar graph with no two 3-cycles sharing an edge. We show that if $Δ(G)\geq 9$, then $χ'_l(G) = Δ(G)$ and $χ''_l(G)=Δ(G)+1.$ We also show that if $Δ(G)\geq 6$, then $χ'_l(G)\leqΔ(G)+1$ and if $Δ(G)\geq 7$, then $χ''_l(G)\leqΔ(G)+2$. All of these results extend to graphs in the projective plane and when $Δ(G)\geq 7$ the results also extend to graphs in the torus and Klein bottle. This second edge-choosability result improves on work of Wang and Lih and of Zhang and Wu. All of our results use the discharging method to prove structural lemmas about the existence of subgraphs with small degree-sum. For example, we prove that if $G$ is a planar graph with no two 3-cycles sharing an edge and with $Δ(G)\geq 7$, then $G$ has an edge $uv$ with $d(u)\leq 4$ and $d(u)+d(v)\leq Δ(G)+2$. All of our proofs yield linear-time algorithms that produce the desired colorings.

description: Group decision-making often benefits from diverse perspectives, yet power imbalances and social influence can stifle minority opinions and compromise outcomes. This prequel introduces an AI-mediated communication system that leverages the Large Language Model to serve as a devil's advocate, representing underrepresented viewpoints without exposing minority members' identities. Rooted in persuasive communication strategies and anonymity, the system aims to improve psychological safety and foster more inclusive decision-making. Our multi-agent architecture, which consists of a summary agent, conversation agent, AI duplicate checker, and paraphrase agent, encourages the group's critical thinking while reducing repetitive outputs. We acknowledge that reliance on text-based communication and fixed intervention timings may limit adaptability, indicating pathways for refinement. By focusing on the representation of minority viewpoints anonymously in power-imbalanced settings, this approach highlights how AI-driven methods can evolve to support more divergent and inclusive group decision-making.

description: Dicke superrandiance is a cooperative phenomenon which arises from the collective coupling of an ensemble of atoms to the electromagnetic radiation. Here we discuss the quantifying of quantum coherence for the Dicke model of superradiance in the mean-field approximation. We found the single-atom $l_1$-norm of coherence is given by the square root of the normalized average intensity of radiation emitted by the superradiant system. This validates quantum coherence as a useful figure of merit towards the understanding of superradiance phenomenon in the mean-field approach. In particular, this result suggests probing the single-atom coherence through the radiation intensity in superradiant systems, which might be useful in experimental realizations where is unfeasible to address atoms individually. Furthermore, given the nonlinear unitary dynamics of the time-dependent single-atom state that effectively describes the system of $N$ atoms, we analyze the quantum speed limit time and its interplay with the $l_1$-norm of coherence. We verify the quantum coherence speeds up the evolution of the superradiant system, i.e., the more coherence stored on the single-atom state, the faster the evolution. These findings unveil the role played by quantum coherence in superradiant systems, which in turn could be of interest for communities of both condensed matter physics and quantum optics.

description: This piece of work presents three cases: Caprica, Productores de Chihuahua and Los Porcicultores, all of which have united their efforts and created enterprises as a strategy through which the participants –small producers- generate networks to associate. This allows them the opportunity to insert in value chains and acquire better conditions for their goods, and at the same time they can give them an added value, and by doing this, they find themselves in a different state of integration and insertion in the value chain, which gives them the opportunity to face the challenges of actual life. This paper visualizes the enterprise from the systemic perspective, and as a collectivity of capabilities. Also, it presents the concept of network - individual or groups interconnected with a certain intention- and of social capital. This approach allows considering social relations as a good through which one has the form to accede to quality resources.

description: A central result in the space geometry of closed twisted ribbons is Calugareanu's theorem (also known as White's formula, or the Calugareanu-White-Fuller theorem). This enables the integer linking number of the two edges of the ribbon to be written as the sum of the ribbon twist (the rate of rotation of the ribbon about its axis) and its writhe. We show that twice the twist is the average, over all projection directions, of the number of places where the ribbon appears edge-on (signed appropriately) - the `local' crossing number of the ribbon edges. This complements the common interpretation of writhe as the average number of signed self-crossings of the ribbon axis curve. Using the formalism we develop, we also construct a geometrically natural ribbon on any closed space curve - the `writhe framing' ribbon. By definition, the twist of this ribbon compensates its writhe, so its linking number is always zero.

description: Let $W$ be a random variable with mean zero and variance $σ^2$. The distribution of a variate $W^*$, satisfying $EWf(W)=σ^2 Ef'(W^*)$ for smooth functions $f$, exists uniquely and defines the zero bias transformation on the distribution of $W$. The zero bias transformation shares many interesting properties with the well known size bias transformation for non-negative variables, but is applied to variables taking on both positive and negative values. The transformation can also be defined on more general random objects. The relation between the transformation and the expression $wf'(w)-σ^2 f''(w)$ which appears in the Stein equation characterizing the mean zero, variance $σ^2$ normal $σZ$ can be used to obtain bounds on the difference $E\{h(W/σ)-h(Z)\}$ for smooth functions $h$ by constructing the pair $(W,W^*)$ jointly on the same space. When $W$ is a sum of $n$ not necessarily independent variates, under certain conditions which include a vanishing third moment, bounds on this difference of the order $1/n$ for classes of smooth functions $h$ may be obtained. The technique is illustrated by an application to simple random sampling.

description: A large number of X-ray sources in globular clusters of galaxies other than the Milky Way has been found with Chandra. We discuss three issues relating to these sources. The X-ray luminosity function (XLF) of the sources in globular clusters of M31 is marginally compatible with the XLF of globular clusters of the Milky Way. The individual XLFs of a dozen elliptical galaxies, after correction for incompleteness, are compatible with one another and show no break; however, the XLF found by adding the individual XLFs of elliptical galaxies has a break at L_x about 5x10(38) ergs/s. For the moment there is no evidence for a difference between the XLFs of sources inside and outside globular clusters of elliptical galaxies. It is not (yet?) possible to decide which fraction of low-mass X-ray binaries in elliptical galaxies outside globular clusters have formed inside globular clusters.

Governing through vague terms : child abuse, community, government and group interests
Creators: name: Cradock, Gerald
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation asks: what is the meaning of child abuse, who should protect children from abuse, and how is child protection accomplished? It posits that child abuse is a vague term as described by philosophers and that it is comprehensible only in relation to two other vague terms - community and government. Vague terms receive sharpenings of meaning within secondary speech genres that are repositories of the tacit knowledge of networked thought collectives. Vague terms appear less vague when they are employed in the primary speech genre of everyday life. Because vague terms appear obvious in the primary speech genre, group interests are able to deploy vague terms as a rhetorical means of advancing their interests. The dissertation uses as its primary research source public submissions to three government inquiries conducted between 1991 and 1995 in British Columbia. The submissions demonstrate the ongoing relations between various group interests concerned with child abuse, community and government. The meaning of child abuse is found to be an emergent and negotiated property of group interests. Vague terms are predictive of the sites and types of ongoing negotiations between group interests over the problem of governing too much and governing too little characteristic of liberal governments.

description: In domain adaptation (DA), the effectiveness of deep learning-based models is often constrained by batch learning strategies that fail to fully apprehend the global statistical and geometric characteristics of data distributions. Addressing this gap, we introduce 'Global Awareness Enhanced Domain Adaptation' (GAN-DA), a novel approach that transcends traditional batch-based limitations. GAN-DA integrates a unique predefined feature representation (PFR) to facilitate the alignment of cross-domain distributions, thereby achieving a comprehensive global statistical awareness. This representation is innovatively expanded to encompass orthogonal and common feature aspects, which enhances the unification of global manifold structures and refines decision boundaries for more effective DA. Our extensive experiments, encompassing 27 diverse cross-domain image classification tasks, demonstrate GAN-DA's remarkable superiority, outperforming 24 established DA methods by a significant margin. Furthermore, our in-depth analyses shed light on the decision-making processes, revealing insights into the adaptability and efficiency of GAN-DA. This approach not only addresses the limitations of existing DA methodologies but also sets a new benchmark in the realm of domain adaptation, offering broad implications for future research and applications in this field.

description: We introduce twisted trilayer graphene (tTLG) with two independent twist angles as an ideal system for the precise tuning of the electronic interlayer coupling to maximize the effect of correlated behaviors. As established by experiment and theory in the related twisted bilayer graphene system, van Hove singularities (VHS) in the density of states can be used as a proxy of the tendency for correlated behaviors. To explore the evolution of VHS in the twist-angle phase space of tTLG, we present a general low-energy electronic structure model for any pair of twist angles. We show that the basis of the model has infinite dimensions even at a finite energy cutoff and that no Brillouin zone exists even in the continuum limit. Using this model, we demonstrate that the tTLG system exhibits a wide range of magic angles at which VHS merge and the density of states has a sharp peak at the charge-neutrality point through two distinct mechanisms: the incommensurate perturbation of twisted bilayer graphene's flat bands or the equal hybridization between two bilayer moiré superlattices.

description: We measured the cross sections of the $^2$H(p,pp)n breakup reaction at E$_p$=16 MeV in three kinematical configurations: the np final-state interaction (FSI), the co-planar star (CST), and an intermediate-star (IST) geometry. The cross sections are compared with theoretical predictions based on the CD Bonn potential alone and combined with the updated 2$π$-exchange Tucson-Melbourne three-nucleon force (TM99'), calculated without inclusion of the Coulomb interaction. The resulting excellent agreement between data and pure CD Bonn predictions in the FSI testifies to the smallness of three-nucleon force (3NF) effects as well as the insignificance of the Coulomb force for this particular configuration and energy. The CST also agrees well whereas the IST results show small deviations between measurements and theory seen before in the pd breakup space-star geometries which point to possible Coulomb effects. An additional comparison with EFT predictions (without 3NF) up to order N$^3$LO shows excellent agreement in the FSI case and a rather similar agreement as for CD Bonn in the CST and IST situations.

description: Exoplanet atmospheres are known to be vulnerable to mass loss through irradiation by stellar X-ray and extreme-ultraviolet emission. We investigate how this high-energy irradiation varies with time by combining an empirical relation describing stellar X-ray emission with a second relation describing the ratio of Solar X-ray to extreme-ultraviolet emission. In contrast to assumptions commonly made when modelling atmospheric escape, we find that the decline in stellar extreme-ultraviolet emission is much slower than in X-rays, and that the total extreme-ultraviolet irradiation of planetary atmospheres is dominated by emission after the saturated phase of high energy emission (which lasts around 100 Myr after the formation of the star). The extreme-ultraviolet spectrum also becomes much softer during this slow decline. Furthermore, we find that the total combined X-ray and extreme-ultraviolet emission of stars also occurs mostly after this saturated phase. Our results suggest that models of atmospheric escape that focus on the saturated phase of high-energy emission are over-simplified, and when considering the evolution of planetary atmospheres it is necessary to follow EUV-driven escape on Gyr timescales. This may make it more difficult to use stellar age to separate the effects of photoevaporation and core-powered mass-loss when considering the origin the planet radius valley.

description: The functional characterization of different neuronal types has been a longstanding and crucial challenge. With the advent of physical quantum computers, it has become possible to apply quantum machine learning algorithms to translate theoretical research into practical solutions. Previous studies have shown the advantages of quantum algorithms on artificially generated datasets, and initial experiments with small binary classification problems have yielded comparable outcomes to classical algorithms. However, it is essential to investigate the potential quantum advantage using real-world data. To the best of our knowledge, this study is the first to propose the utilization of quantum systems to classify neuron morphologies, thereby enhancing our understanding of the performance of automatic multiclass neuron classification using quantum kernel methods. We examined the influence of feature engineering on classification accuracy and found that quantum kernel methods achieved similar performance to classical methods, with certain advantages observed in various configurations.

description: NICU nurses face considerable psychological stress due to the demanding nature of their work, impacting their well-being and performance. Understanding the coping strategies and support systems available to these nurses is crucial for improving their mental health and job satisfaction. This study aims to identify and analyze the coping strategies and support systems that NICU nurses in Saudi Arabia utilize to manage work-related stress. A qualitative descriptive design was employed to explore the experiences of 20 NICU nurses from various hospitals in Saudi Arabia. Data were collected through semi-structured interviews and analyzed using thematic analysis to identify key coping strategies and support systems. The thematic analysis revealed eight primary coping strategies: problem-solving, seeking emotional support, maintaining a work-life balance, mindfulness and relaxation techniques, professional development, physical exercise, spiritual practices, and humor. Six key support systems were identified: peer support, family support, professional counseling services, institutional support programs, religious and spiritual guidance, and community support networks. The findings highlight the diverse coping mechanisms and support systems that NICU nurses rely on to manage stress. Effective coping strategies and robust support systems are essential for maintaining the psychological well-being of NICU nurses. The study recommends the implementation of comprehensive support programs within healthcare institutions, including regular mental health assessments, professional counseling, and peer support initiatives. Enhancing these resources can improve job satisfaction, reduce burnout, and promote better patient care outcomes.

description: The existence of dark radiation that is completely decoupled from the standard model in the early Universe leaves open the possibility of an associated dark radiation isocurvature mode. We show that the presence of dark radiation isocurvature leads to spatial variation in the primordial abundances of helium and deuterium due to spatial variation in $N_{\rm eff}$ during Big Bang nucleosynthesis. We use the result to constrain the existence of such an isocurvature mode on scales down to $\sim 1$ Mpc scales. By measuring the excess variance in the primordial helium to hydrogen and deuterium to hydrogen ratio in different galaxies, we constrain the variance in average isocurvature in a galaxy to be less than $0.13/Δ\bar{N}_{\rm eff}$ at 95\% confidence. Here $Δ\bar{N}_{\rm eff}$ is the spatially averaged increase in $N_{\rm eff}$ due to the additional dark radiation component.

description: The objective is to make the investment sensibility analysis in drop irrigation by gravity in sugar cane production, there are three variables involved into the sensibility analysis for both of the irrigation systems: Cane production by hectare (it was sensibilized to low prices), sell price for sugar cane ton (it was sensibilized to low prices), and variations in the production's direct costs (sensibilized to high prices). The Novelo's methodology for sensibility analysis (1944) was used. The three variables involved into the sensibility analysis showed differences to support the outcome results got with the irrigation drop system over the irrigation gravity system by drop.

description: We consider black holes which form from an initially spherically symmetric super-Hubble perturbation of a cosmological background filled by a perfect fluid $p=w ρ$ with $w\in (0,1]$. Previous work has shown that when $w = 1/3$ (radiation), there is a critical threshold for black hole formation ($δ_c$), which, to a very good approximation, only depends upon the curvature of the compaction function around its peak value. We find that this generalizes to all $w\gtrsim 1/3$; for smaller $w$s the knowledge of the full shape of the compaction function is necessary. We provide analytic approximations for $δ_c$ which are accurate for $w\in [1/3,1]$.

description: In almost all types of vegetation there are species that can cause toxicity to livestock that consumes. The poisoning caused problems in many different animals can affect reproduction, weight gain, and even death. These problems are causing economic losses in the livestock industry it is necessary to quantify but very difficult to achieve it. In Sonora, has been diagnosed rangeland of overgrazing, which manifests itself in a deterioration that diminishes the species desirable and undesirable increases, among these plants are toxic. We have identified 184 species that are toxic and within them there are 59 species that consume livestock and cause problems. For the foregoing are raised by this study, in order to try to estimate the economic impact that cause toxic plants on livestock productivity in Sonora. We used various sources of information for developing analysis and calculations that may come closer to quantifying the economic effects. We used the methodology described by Nielsen et al. (1990) for estimating these losses. The results show that a conservative estimate of the economic effect of these plants on sonorense livestock may represent a loss of around 90 million pesos a year.

description: We present the results of the spectroscopic follow up of the QUBRICS survey. The selection method is based on a machine learning approach applied to photometric catalogs, covering an area of $\sim$ 12,400 deg$^2$ in the Southern Hemisphere. The spectroscopic observations started in 2018 and identified 55 new, high-redshift (z>=2.5), bright (i<=18) QSOs, with the catalog published in late 2019. Here we report the current status of the survey, bringing the total number of bright QSOs at z<=2.5 identified by QUBRICS to 224. The success rate of the QUBRICS selection method, in its most recent training, is estimated to be 68%. The predominant contaminant turns out to be lower-z QSOs at z<2.5. This survey provides a unique sample of bright QSOs at high-z available for a number of cosmological investigations. In particular, carrying out the redshift drift measurements (Sandage Test) in the Southern Hemisphere, using the HIRES spectrograph at the 39m ELT, appears to be possible with less than 2500 hours of observations spread over 30 targets in 25 years.
