Optimality of private quantum channels

description: We addressed the question of optimality of private quantum channels. We have shown that the Shannon entropy of the classical key necessary to securely transfer the quantum information is lower bounded by the entropy exchange of the private quantum channel $\cal E$ and von Neumann entropy of the ciphertext state $\varrho^{(0)}$. Based on these bounds we have shown that decomposition of private quantum channels into orthogonal unitaries (if exists) is optimizing the entropy. For non-ancillary single qubit PQC we have derived the optimal entropy for arbitrary set of plaintexts. In particular, we have shown that except when the (closure of the) set of plaintexts contains all states, one bit key is sufficient. We characterized and analyzed all the possible single qubit private quantum channels for arbitrary set of plaintexts. For the set of plaintexts consisting of all qubit states we have characterized all possible approximate private quantum channels and we have derived the relation between the security parameter and the corresponding minimal entropy.

On the validity of microscopic calculations of double-quantum-dot spin qubits based on Fock-Darwin states

description: We consider two typical approximations that are used in the microscopic calculations of double-quantum dot spin qubits, namely, the Heitler-London (HL) and the Hund-Mulliken (HM) approximations, which use linear combinations of Fock-Darwin states to approximate the two-electron states under the double-well confinement potential. We compared these results to a case in which the solution to a one-dimensional Schrödinger equation was exactly known and found that typical microscopic calculations based on Fock-Darwin states substantially underestimate the value of the exchange interaction, which is the key parameter that controls the quantum dot spin qubits. This underestimation originates from the lack of tunneling of Fock-Darwin states, which is accurate only in the case with a single potential well. Our results suggest that the accuracies of the current two-dimensional molecular-orbit-theoretical calculations based on Fock-Darwin states should be revisited since underestimation could only deteriorate in dimensions that are higher than one.
A Functional Boundary Argument for the Riemann Hypothesis via Omega-Coherence
Creators: name: Sambey, Stanley Everett
Publisher: name: Zenodo
Year: 2025

description: We propose a coherence-based functional Ω(C, s) to constrain the nontrivial zeros of the Riemannzeta function ζ(s) to the critical line Re(s) = 1/2, supporting the Riemann Hypothesis. Rootedin the Enhanced Law of Observation (ELO), this functional models ζ(s) as a coherence amplitudein a probabilistic Data Substrate ψn on a topological fibration S1 → S3 → CP1, with zeros asobserver-driven collapses governed by the Coherence-Consciousness-Locality (CCL) principle, co-herence operator ˆC, and emotional fields Ei(θ, t) (e.g., love, fear). Memory dynamics and biologicaldiversity ensure maximal coherence on the critical line, testable via 10−3 Hz signals in the Collec-tive Observer Network (CON). Variational eigenvalue framing and M¨obius symmetry reinforce theargument, suggesting the Hypothesis reflects fundamental coherence in substrate-observer dynam-ics, linking to Millennium Problems (P vs NP, Yang–Mills, Hodge, Navier-Stokes, Birch) throughtopological and emotional unification. Detailed proofs are in supplemental material.

description: We propose a practical method for analyzing stability of Q-balls for the whole parameter space, which includes the intermediate region between the thin-wall limit and thick-wall limit as well as Q-bubbles (Q-balls in false vacuum), using the catastrophe theory. We apply our method to the two concrete models, $V_3=m^2ϕ^2/2-μϕ^3+λϕ^4$ and $V_4=m^2ϕ^2/2-λϕ^4+ϕ^6/M^2$. We find that $V_3$ and $V_4$ Models fall into {\it fold catastrophe} and {\it cusp catastrophe}, respectively, and their stability structures are quite different from each other.

A Variational Functional Argument for the Riemann Hypothesis via the Ω-Constraint
Creators: name: Sambey, Stanley Everett
Publisher: name: Zenodo
Year: 2025

description: We introduce a real-valued functional Ω(C, s), defined over the critical strip 0 <Re(s) < 1, which enforces a coherence constraint between the Riemann zeta functionζ(s) and a deviation penalty term centered at the critical line Re(s) = 1/2. Thefunctional selects Re(s) = 1/2 as the unique axis where nontrivial zeros may exist, asany solution off-axis would require ζ(s) to equal a deterministic, monotonic functionof real part—a condition that contradicts the known oscillatory behavior of ζ(s) in thecomplex domain.
Methodological Issues in Conducting Research on the Disadvantaged and Their Implications for Designing and Evaluating Programs for the Disadvantaged

description: This paper examines three methodological issues relating to research on the disadvantaged. Examination of these issues is important not only for researchers but also for those involved in designing, administering, and evaluating programs for the disadvantaged. My orientation for this paper comes from two sources. First, I have conducted research in the Chicago area on government programs designed to provide employment for the disadvantaged. In these programs a company received a subsidy to hire, train, and retrain the so··called hard-core. Second, I have been involved in a literature review of studies concerned with psychological and sociological factors which affect the recruitment, hiring, and training of the disadvantaged. Although I have not been involved in sheltered workshop programs, many of the basic issues involved in the areas with which I dealt should be generalizable to the sheltered workshop situation.
The Governmentality of Biodiversity in the EU’s Common Fisheries Policy
Creators: name: Nøhr, Andreas Aagaard
Publisher: name: The Interdisciplinary Journal of International Studies
Year: 2013

description: In recent years, the global loss of biodiversity has been an increasing concern for many governments around the planet. Solving this problem requires working together and reforming existing policy frameworks. This paper explores how biodiversity is governed under the EU’s Common Fisheries Policy. Drawing upon Foucault’s governmentality concept the paper advances its own concept “governmentality of biodiversity”. The author identifies three overall arguments for preserving biodiversity that take their basis in self-centered values, de-centered values, or intrinsic values. The author analyzes and determines how the governmentality of biodiversity on the basis of the knowledge and rationality embedded in de-centered and intrinsic values promotes new goals for governing the Common Fisheries Policy. It is concluded that in the different mechanisms of power, the governmentality of biodiversity yields to the rationality of power exercised by member states in the EU.

A Variational Functional Argument for the Riemann Hypothesis via the Ω-Constraint
Creators: name: Sambey, Stanley Everett
Publisher: name: Zenodo
Year: 2025

description: This paper introduces a novel function, C(s)C(s)C(s), derived from a generalized Consciousness Scale C(ψ)C(ψ)C(ψ) within the Unified Theory of Observation. We interpret the nontrivial zeros of the Riemann zeta function, ζ(s), as loci of balance between information potential and expression, formalized as Ω(C, s) = ζ(s) - C(s). The function C(s) integrates logistic, sigmoid, logarithmic, and step functions that map onto consciousness-data interaction thresholds. We conjecture that Ω(C, s) = 0 if and only if Re(s) = ½, offering a naturalistic, information-theoretic justification for the critical line hypothesis. This formulation provides a unifying bridge between quantum informational structures, fractal growth, and analytic number theory.

description: We study the effects of mergers and acquisitions on industry dynamics. We develop an infinite horizon model of a competitive industry, which features mergers, entry, exit, and investment by heterogeneous firms. Merger synergies arise from improvements in productivity and cost efficiencies. We characterize the time-series and cross-sectional evolution of firm productivities and merger opportunities in a rational expectations equilibrium. Consistent with the empirical evidence, our model generates procyclical entry and merger activity, as well as counter-cyclical exit. The presence of a merger market induces higher entry rates and lower exit rates, reduces the counter-cyclicality of exit, and increases the mean and variance of the cross-sectional distribution of firm-level productivities. While entry and exit induce the mean productivity to be counter-cyclical, this pattern is reversed when the possibility of mergers is taken into account.

Rootedin the Unified Theory of Observation (UTO), this functional models ζ(s) as a coherence amplitude ina probabilistic Data Substrate, ψn(x), with zeros representing observer-driven collapses governed bythe unified equation Ω(C, ψ). The Coherence-Consciousness-Locality (CCL) principle, Energy CreationMatrix, and Logic Virus operator ensure maximal coherence on the critical line, while the GravityReturn stabilizes the collapse process. We extend the argument with variational eigenvalue framing,M¨obius invariance, and symmetry considerations, suggesting that the Riemann Hypothesis reflects afundamental coherence condition in substrate-observer dynamics.Keywords: Riemann Hypothesis, Omega-Coherence, Unified Theory of Observation, Law of Ob-servation, Zeta Function, Critical Line, Coherence Functions, M¨obius Invariance, Observer-SubstrateInteraction.

Swaziland in Transition

Publisher: name: The Interdisciplinary Journal of International Studies
Year: 2013

description: The focus of this paper is on the structural and cognitive challenges civil society activists meet in their struggle for democracy in the Kingdom of Swaziland. The research is motivated by an internship with the Danish labour union federation LO/FTF Council and its affiliate in Swaziland, SFTU, while collaborating with grassroots activists who fight for democracy. The research is based on a survey of 100 Swazis and on presentations of two leading democracy activists. The empirical data is contextually analysed with a range of complementary theories within the social sciences. The analysis explains the complexity in the challenges from different approaches both focusing on the power of tradition and political modernisation. It is concluded that the challenges are related to more than rational issues but rather to a set of cognitive and structural factors relating to the power of tradition and the dilemmas in political modernisation.

Publisher: name: MDPI

description: The increasing share of volatile, renewable energy sources rises the demand for consumers who can shift their electrical power demand in time. In theory, the industrial sector offers great potential here, as it accounts for a large proportion of electricity demand. However, the heterogeneous structure of facilities in factories and the concerns of operators regarding data security and process control often prevent the implementation of demand side management measures in this sector. In order to counteract these obstacles, this paper presents a general mathematical framework for modelling and evaluating different types of inherent energy storages (IES) which typically can be found in industrial production systems. The method can be used to calculate the flexibility potential of the IES in a factory with focus on hysteresis-controlled devices and make the potential visible and usable for power grid stabilization. The method is applied in a typical production line from metalworking industry to provide live monitoring of the current flexibility potential of selected devices.
Caught in the Clash amid Customs and Market: A Case of the Poor and Marginalized Rural Population’s Access to Land in Zambia

description: The paper is a case study analyzing the effects of the Zambian Lands Act of 1995. The problem area centers on the question as to why the market-based land reform of 1995 in Zambia has not, despite its purpose, improved the access to land for the poor and marginalized rural population. The ability to acquire land titles in Zambia highly depends on (i) access to knowledge, (ii) legal access, (iii) access through social identity, and (iv) access to authority. The findings of this paper reveal a reality in which mostly Zambian elites, chiefs, and foreign investors benefit from the prevalent power structures gaining exclusive control over land. Additionally, problems such as complicated and costly bureaucratic procedures as well as civil status, traditional hierarchies, and corruptive behavior weaken the poor and marginalized rural population’s access to land. The paper concludes that the Zambian market-based land reform in 1995 has not benefited the poor and marginalized rural population’s access to land, but has intensified inequalities.

description: We classify all possible allowed constitutive relations of relativistic fluids in a statistical mechanical limit using the Schwinger-Keldysh effective action for hydrodynamics. We find that microscopic unitarity enforces genuinely new constraints on the allowed transport coefficients that are invisible in the classical hydrodynamic description; they are not implied by the second law or the Onsager relations. We term these conditions Schwinger-Keldysh positivity and provide explicit examples of the various allowed terms.

description: We show that despite stringent constraints on the shape of the main part of the CMB spectrum, there is considerable room for its modification within its Rayleigh-Jeans (RJ) end, $ω\ll T_{\rm CMB}$. We construct explicit New Physics models that give an order one (or larger) increase of photon count in the RJ tail, which can be tested by existing and upcoming experiments aiming to detect the cosmological 21 cm emission/absorption signal. This class of models stipulates the decay of unstable particles to dark photons, $A'$, that have a small mass, $m_{A'} \sim 10^{-14} - 10^{-9}$ eV, non-vanishing mixing angle $ε$ with electromagnetism, and energies much smaller than $T_{\rm CMB}$. The non-thermal number density of dark photons can be many orders of magnitude above the number density of CMB photons, and even a small probability of $A'\to A$ oscillations, for values of as small as $ε\sim 10^{-9}$, can significantly increase the number of RJ photons. In particular, we show that resonant oscillations of dark photons into regular photons in the interval of redshifts $20 < z < 1700$ can be invoked as an explanation of the recent tentative observation of a stronger-than-expected absorption signal of 21 cm photons. We present a model that realizes this possibility, where milli-eV mass dark matter decays to dark photons, with a lifetime longer than the age of the Universe.

The Construction of Masculinity in International Relations
Creators: name: Fritzsche, Nora
Publisher: name: The Interdisciplinary Journal of International Studies
Year: 2013

description: International politics is characterized by a lack of women. The few women holding high political positions are more likely to be criticized and judged based upon, what the author calls, ‘the construction of masculinity in international relations’. Tracing the origin and logic of this construction, the article critiques the dominant theories of international relations (namely, realism and liberalism) and argues for the aptness of a radical feminist social constructivist approach to the study of international politics. The article also illuminates the strong focus on men and men’s perspectives of these influential mainstream theories on their conception and interpretation of war. An examination of the concept of war reveals how masculinity and femininity are portrayed on matters of war and national security and what side effects this has on women in politics, particularly women with political positions.

description: We present results of a timing analysis of various isolated pulsars using ESA's \emph{XMM-Newton} observatory. Isolated pulsars are useful for calibration purposes because of their stable emission. We have analyzed six pulsars with different pulse profiles in a range of periods between 15 and 200 ms. All observations were made using the \emph{EPIC-pn camera} in its faster modes (Small window, Timing and Burst modes). We investigate the relative timing accuracy of the camera by comparing the pulse periods determined from the \emph{EPIC-pn camera} observations with those from radio observations. As a result of our analysis we conclude that the relative timing accuracy of the \emph{EPIC-pn camera} is of the order of $1\times 10^{-8}$.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: In this paper we consider the warped AdS$_{3}$ black hole solution of topologically massive gravity with a negative cosmological constant, and we investigate the possibility that it acts as a particle accelerator by analyzing the energy in the center of mass (CM) frame of two colliding particles in the vicinity of its horizon, which is known as the Bañados, Silk and West (BSW) process. Mainly, we show that the critical angular momentum $(L_c)$ of the particle decreases when the parameter that controls the stretching deformation ($ν$) increases. Also, we show that despite the particle with $L_c$ can exist for certain values of the conserved energy outside the horizon, it will never reach the event horizon; therefore, the black hole can not act as a particle accelerator with arbitrarily high CM energy on the event horizon. However, such particle could also exist inside the outer horizon being the BSW process possible on the inner horizon. On the other hand, for the extremal warped AdS$_{3}$ black hole, the particle with $L_c$ and energy $E$ could exist outside the event horizon and the CM energy blows up on the event horizon if its conserved energy fulfill the condition $E^{2}>\frac{(ν^{2}+3)l^{2}}{3(ν^{2}-1)}$, being the BSW process possible.

description: Merchants operations involves valuing and hedging the cash flows of commodity and energy conversion assets as real options based on stochastic models that inevitably embed model error. In this paper we quantify how empirically calibrated model errors about the futures price term structure affect the valuation and hedging of commodity storage assets, specifically the storage of natural gas, an important energy source. We also explore ways to mitigate the impact of these errors. Our analysis demonstrates the differential impact of term structure model error on natural gas storage valuation versus hedging. We also propose an effective approach to deal with the negative effect of such model error on factor hedging, a specific hedging approach. More generally, our work suggests managerial principles for option valuation and hedging in the presence of term structure model error. These principles should have relevance for the merchant management of other commodity conversion assets and for the management of financial options that also depend on term structure dynamics.

description: In this paper we find and explore the correspondence between quivers, torus knots, and combinatorics of counting paths. Our first result pertains to quiver representation theory -- we find explicit formulae for classical generating functions and Donaldson-Thomas invariants of an arbitrary symmetric quiver. We then focus on quivers corresponding to $(r,s)$ torus knots and show that their classical generating functions, in the extremal limit and framing $rs$, are generating functions of lattice paths under the line of the slope $r/s$. Generating functions of such paths satisfy extremal A-polynomial equations, which immediately follows after representing them in terms of the Duchon grammar. Moreover, these extremal A-polynomial equations encode Donaldson-Thomas invariants, which provides an interesting example of algebraicity of generating functions of these invariants. We also find a quantum generalization of these statements, i.e. a relation between motivic quiver generating functions, quantum extremal knot invariants, and $q$-weighted path counting. Finally, in the case of the unknot, we generalize this correspondence to the full HOMFLY-PT invariants and counting of Schröder paths.

description: This research investigated the reciprocal relationship between mental models of conflict and various forms of dysfunctional social relations in organizations, including experiences of task and relationship conflicts, interpersonal hostility, workplace ostracism, and abusive supervision. We conceptualize individual differences in conflict construals as reflecting variation in people's belief structures about conflict and explore how different elements in people's associative networks-in particular, their beliefs about their best and worst strategy in conflict-relate to their personality, shape their experiences of workplace conflict, and influence others' behavioral intentions toward them. Five studies using a variety of methods (including cross-sectional surveys, a 12-week longitudinal diary study, and an experiment) show that the best strategy beliefs relate in theoretically meaningful ways to individuals' personality, shape social interactions and relationships significantly more than the worst strategy beliefs, and are updated over time as a result of individuals' ongoing experiences of conflict.

description: The measurement and control of the temperature in microscopic systems, which are increasingly required in diverse applications, are fundamentally important. Yet, the measurement of the three-dimensional (3D) temperature distribution in microscopic systems has not been demonstrated. Here, we propose and experimentally demonstrate the measurement of the 3D temperature distribution by exploiting the temperature dependency of the refractive index (RI). Measurement of the RI distribution of water makes it possible to quantitatively obtain its 3D temperature distribution above a glass substrate coated with gold nanorods with sub-micrometer resolution, in a temperature range of 100C and with a sensitivity of 2.88C. The 3D temperature distributions that are obtained enable various thermodynamic properties including the maximum temperature, heat flux, and thermal conductivity to be extracted and analyzed quantitatively.

description: We use singular Euclidean solutions to find multi-particle production cross sections in field theories. We investigate a family of time-dependent O(3) symmetrical solutions of the Yang--Mills equations, which govern the isotropic high-energy gauge boson production. At low energies our approach reproduces the instanton-induced cross sections. For higher energies we get new results. In particular, we show that the cross section for isotropic multiparticle production remains exponentially small in the running gauge coupling constant. The result applies both to the baryon number violation in the electro-weak theory and to the QCD jet production. We find that the isotropic multi-gluon production cross section falls off approximately as a ninth power of energy but possibly might be observable

description: In this study, we present a straightforward approach for functional cell-based screening by co-encapsulation of secretor yeast cells and reporter mammalian cells in millions of individual agarose-containing microdroplets. Our system is compatible with ultra-high-throughput selection utilizing standard fluorescence-activated cell sorters (FACS) without need of extensive adaptation and optimization. In a model study we co-encapsulated murine interleukin 3 (mIL-3)-secreting S. cerevisiae cells with murine Ba/F3 reporter cells, which express green fluorescent protein (GFP) upon stimulation with mIL-3, and could observe specific and robust induction of fluorescence signal compared to a control with yeast cells secreting a non-functional mIL-3 mutant. We demonstrate the successful enrichment of activating mIL-3 wt-secreting yeast cells from a 1:10,000 dilution in cells expressing the inactive cytokine variant by two consecutive cycles of co-encapsulation and FACS. This indicates the suitability of the presented strategy for functional screening of high-diversity yeast-based libraries and demonstrates its potential for the efficient isolation of clones secreting bioactive recombinant proteins.
Recovering the Inflationary Potential

description: A procedure is developed for the recovery of the inflationary potential over the interval that affects astrophysical scales ($\approx 1\Mpc - 10^4\Mpc$). The amplitudes of the scalar and tensor metric perturbations and their power-spectrum indices, which can in principle be inferred from large-angle CBR anisotropy experiments and other cosmological data, determine the value of the inflationary potential and its first two derivatives. From these, the inflationary potential can be reconstructed in a Taylor series and the consistency of the inflationary hypothesis tested. A number of examples are presented, and the effect of observational uncertainties is discussed.

Neutrino mass hierarchy and Majorana CP phases within the Higgs triplet model at the LHC

Year: 2007

description: Neutrino masses may be generated by the VEV of an $SU(2)_L$ Higgs triplet. We assume that the doubly charged component of such a triplet has a mass in the range of several 100 GeV, such that it is accessible at LHC. Its decay into like-sign leptons provides a clean experimental signature, which allows for a direct test of the neutrino mass matrix. By exploring the branching ratios of this decay into leptons of various flavours, we show that within this model the type of the neutrino mass spectrum (normal, inverted or quasi-degenerate) might actually be resolved at the LHC. Furthermore, we show that within the Higgs triplet model for neutrino mass the decays of the doubly charged scalar into like-sign lepton pairs at the LHC provide a possibility to determine the Majorana CP phases of the lepton mixing matrix.

description: A relatively simple analytical formula is derived for the energy spectrum of $W$ boson in top quark decays $t\to Wb$ including ${\cal O}(α_s)$ radiative corrections. We discuss the accuracy of this formula and compare it to a more general albeit more complicated one derived in \cite{CJK}~. A Monte Carlo algorithm for generation of $W$ energy spectrum is briefly described.

Memorandum: Interest Rates and Ceiling Rates

description: This memo covers two separate topics. In the first, I discuss the topics determining Interest rates and the effect that I expect these factors to have on Interest rates in 1967. Then I consider the role of present ceilings on rates paid to depositors by commercial banks and other thrift institutions. The two topics are related in part because the rates are themselves related in well functioning markets for money and securities and in part because ceilings or other restrictions that prevent the rates paid by banks and other institutions from adjusting disrupt well established patterns of resource allocation and force individuals to search for new mans of holding assets.
Optimal Compression and Transmission Rate Control for Node-Lifetime Maximization

description: We consider a system that is composed of an energy constrained sensor node and a sink node, and devise optimal data compression and transmission policies with an objective to prolong the lifetime of the sensor node. While applying compression before transmission reduces the energy consumption of transmitting the sensed data, blindly applying too much compression may even exceed the cost of transmitting raw data, thereby losing its purpose. Hence, it is important to investigate the trade-off between data compression and transmission energy costs. In this paper, we study the joint optimal compression-transmission design in three scenarios which differ in terms of the available channel information at the sensor node, and cover a wide range of practical situations. We formulate and solve joint optimization problems aiming to maximize the lifetime of the sensor node whilst satisfying specific delay and bit error rate (BER) constraints. Our results show that a jointly optimized compression-transmission policy achieves significantly longer lifetime (90% to 2000%) as compared to optimizing transmission only without compression. Importantly, this performance advantage is most profound when the delay constraint is stringent, which demonstrates its suitability for low latency communication in future wireless networks.

description: Projecting a year or more ahead is made difficult by the number of uncertainties and often differences between forecasts reflecting differences in assumption«, At present, as so often in the past, a principle problem is to forecast government fiscal and monetary policy. IDS does not report a final decision on the fiscal 1973 budget and does not mention the fiscal 1974 budget. They hope monetary policy will become less inflationary and mention a 5% rate of growth as a target.

description: We analyze the dynamics of occupation probabilities for a certain type of design models by the use of two different methods. On the one hand we present some numerical calculations for two concrete interactions which point out that the occurrence of statistical dynamics depends on the interaction structure. Furthermore we show an analytical derivation for an infinite system that yields statistical behaviour for the average over the whole ensemble of interactions in the Van Hove-limit.

Physical and chemical characterization of nanosecond pulsed streamer discharges in water
Creators: name: Rataj, Raphael
Publisher: name: Universität Rostock
Year: 2023
Subjects: subject: 500 Natural sciences
subject: 530 Physics

description: The physical characteristics of pulsed streamer discharges in water and their chemistry were investigated, with a focus on hydrogen peroxide. The discharges were studied with regard to the pulse parameters, namely amplitude, edge steepness, and pulse duration, as well as the conductivity of the water by means of electro-optical and electro-chemical single discharge diagnostics. The characteristics of hydrogen peroxide production could be explained by the development of the discharge filaments. The energy efficiency was determined by the dielectric time constant of the system.
