description: We report on the fabrication of nanocontacts by indentation of an ultrathin insulating photoresist layer deposited on various types of conductive structures. A modified atomic force microscope (AFM) designed for local resistance measurements is used as a nanoindenter. The nanoindentation is performed while measuring continuously the resistance between the conductive tip of the AFM and the conductive layer, which is used as the trigger parameter to stop the indentation. This allows an extremely accurate control of the indentation process. The indented hole is subsequently filled by a metal to create a contact on the underlying layer. We show that nanocontacts in the range of 1 to 10 nm2 can be created with this technique.

description: Recently, a non-trivial $4D$ Einstein-Gauss-Bonnet (EGB) theory of gravity, by rescaling the GB coupling parameter as $α/(D-4)$, was formulated in \cite{Glavan:2019inb}, which bypasses Lovelock's theorem and avoids Ostrogradsky instability. The theory admits a static spherically symmetric black hole, unlike $5D$ EGB or general relativity counterpart, which can have both Cauchy and event horizons. We generalize previous work, on gravitational lensing by a Schwarzschild black hole, in the strong and weak deflection limits to the $4D$ EGB black holes to calculate the deflection coefficients $\bar{a}$ and $\bar{b}$, while former increases and later decrease with increasing $α$. We also find that the deflection angle $α_D$, angular position $θ_{\infty}$ and $u_{m}$ decreases, but angular separation $s$ increases with $α$. The effect of the GB coupling parameter $α$ on positions and magnification of the source relativistic images is discussed in the context of SgrA* and M87* black holes. A brief description of the weak gravitational lensing using the Gauss-Bonnet theorem is presented.

description: Kondo correlation in a spin polarized quantum dot (QD) results from the dynamical formation of a spin singlet between the dot's net spin and a Kondo cloud of electrons in the leads, leading to enhanced coherent transport through the QD. We demonstrate here significant dephasing of such transport by coupling the QD and its leads to potential fluctuations in a near by 'potential detector'. The qualitative dephasing is similar to that of a QD in the Coulomb Blockade regime in spite of the fact that the mechanism of transport is quite different. A much stronger than expected suppression of coherent transport is measured, suggesting that dephasing is induced mostly in the 'Kondo cloud' of electrons within the leads and not in the QD.

description: Nowadays computational complexity of fast walsh hadamard transform and nonlinearity for Boolean functions and large substitution boxes is a major challenge of modern cryptography research on strengthening encryption schemes against linear and differential attacks. Time and memory complexities of the best existing algorithm for computing fast walsh hadamard transform and non linearity for n x m substitution boxes (n >= 16;m >= 16) is O(2^(n+m)). This paper proposes three new acceleration methods that improve the computation time for parallelized walsh matrix up to 39 folds and the computation time for non linearity degree up to 563 folds, defining and accessing walsh matrix transpose, and incorporating an important part of computation process of non linearity in the computation algorithm of walsh matrix. The validity of the proposed algorithms is verified by means of simulation and experimentation and the overall analysis of resource consumption of proposed algorithms was compared with previous ones.

Hotel management in the city of Kragujevac, in time prior to transition period was based upon public company CTC “Kragujevac” which was reorganized in current terms of property transformation and which has undergone the program restructuring into contemporary hotel system. This case study deals with the expected tendencies in hotel industry of Kragujevac, derived from conducted privatization process of CTC “Kragujevac” into resulting company HTC “Šumarice”. The core of the elaborate is on recognition of future development perspectives of CTC “Kragujevac” coming out as result of property transformation and overall structural changes. Future development direction of HTC “Šumarice” is based upon the strategic leadership which understands continual adjustment of market services to the demands and regularities of the contemporary market as well as the changes in business manner in accordance to touristic market, toward wishes and needs of hotel clients.
Temporally Varying Universal Gravitational "Constant" and Speed of Light in Energy Momentum Squared Gravity

description: Energy Momentum Squared Gravity (EMSG) is a cosmological model where the scale factor is non vanishing at all times and hence does not favor big bang cosmology. However, the profile of density in the radiation dominated universe shows that EMSG supports inflationary cosmology. Inflationary cosmological models are successful in providing convincing answers to major cosmological issues like horizon problem, flatness problem and small value of cosmological constant but hitherto no model of inflation has been observationally confirmed. Owing to this, Varying Speed of Light (VSL) were introduced which are a class of cosmological models which disfavor inflation and propose an alternative route to solve these cosmological issues by just allowing the speed of light (and Newtonian Gravitational constant) to vary. VSL theories were motivated to address the shortcomings of inflation but do not address the shortcomings related to the initial big bang singularity. In this spirit, we present here a novel cosmological model which is free from both the "initial big bang singularity" and "inflation" by incorporating a mutually varying speed of light $c(t)$ and Newtonian gravitational constant $G(t)$ in the framework of EMSG. We report that in EMSG, for a dust universe ($ω=0$), cosmological models for a time varying $c(t)$ and $G(t)$ and constant $c$ and $G$ are indistinguishable, whereas for a radiation dominated universe ($ω= 1/3$), a mutually varying $c(t)$ and $G(t)$ provides an exiting alternative to inflationary cosmology which is also free from initial big bang singularity. We further report that for an ansatz of scale factor representing a bouncing cosmological model, the VSL theory can be applied to a quadratic $T$ gravity model to get rid of "inflation" and "big bang singularity" and concurrently solve the above mentioned cosmological enigmas.

Massive torsion modes, chiral gravity, and the Adler-Bell-Jackiw anomaly

Year: 2003

description: Regularization of quantum field theories introduces a mass scale which breaks axial rotational and scaling invariances. We demonstrate from first principles that axial torsion and torsion trace modes have non-transverse vacuum polarization tensors, and become massive as a result. The underlying reasons are similar to those responsible for the Adler-Bell-Jackiw (ABJ) and scaling anomalies. Since these are the only torsion components that can couple minimally to spin 1/2 particles, the anomalous generation of masses for these modes, naturally of the order of the regulator scale, may help to explain why torsion and its associated effects, including CPT violation in chiral gravity, have so far escaped detection. As a simpler manifestation of the reasons underpinning the ABJ anomaly than triangle diagrams, the vacuum polarization demonstration is also pedagogically useful. In addition it is shown that the teleparallel limit of a Weyl fermion theory coupled only to the left-handed spin connection leads to a counter term which is the Samuel-Jacobson-Smolin action of chiral gravity in four dimensions.

description: The crisis of values has predictable consequences, primarily economic. It affects the motivation of workers, reducing the competitive spirit, striving for excellence, focusing on achievements and thoroughness in performing duties. The crisis of values has origin in dualism of anti-work and work ethic in Serbia. To this phenomenon we should add current exploitative capitalism, where workers are maximum exploited for miserable compensation. When these factors add to the historical legacy and mentality, we get the rounded picture for the crisis of values in Serbia. Changes in values are a prerequisite of successful social change. It is necessary, therefore, to dispense with the remnants of feudalism, the Turkish oppression, communism and the crisis of the nineties, and affirm the work ethic.

description: We propose a modified gravity theory that propagates only two local gravitational degrees of freedom and that does not have an Einstein frame. According to the classification in JCAP 01 (2019) 017 [arXiv:1810.01047 [gr-qc]], this is a type-II minimally modified gravity theory. The theory is characterized by the gravitational constant $G_{\rm N}$ and a function $V(ϕ)$ of a non-dynamical auxiliary field $ϕ$ that plays the role of dark energy. Once one fixes a homogeneous and isotropic cosmological background, the form of $V(ϕ)$ is determined and the theory no longer possesses a free parameter or a free function, besides $G_{\rm N}$. For $V'(ϕ) = 0$ the theory reduces to general relativity (GR) with $G_N$ being the Newton's constant and $V=const.$ being the cosmological constant. For $V'(ϕ) \ne 0$, it is shown that gravity behaves differently from GR but that GR with $G_{\rm N}$ being the Newton's constant is recovered for weak gravity at distance and time scales sufficiently shorter than the scale associated with $V(ϕ)$. Therefore this theory provides the simplest framework of cosmology in which deviations from GR can be tested by observational data.

description: We present x-ray reflectivity and diffuse scattering measurements from the liquid surface of pure potassium. They strongly suggest the existence of atomic layering at the free surface of a pure liquid metal with low surface tension. Prior to this study, layering was observed only for metals like Ga, In and Hg, the surface tensions of which are 5-7 fold higher than that of potassium, and hence closer to inducing an ideal "hard wall" boundary condition. The experimental result requires quantitative analysis of the contribution to the surface scattering from thermally excited capillary waves. Our measurements confirm the predicted form for the differential cross section for diffuse scattering, $dσ/dΩ\sim 1/q_{xy}^{2-η}$ where $η= k_BT q_z^2/2πγ$, over a range of $η$ and $q_{xy}$ that is larger than any previous measurement. The partial measure of the surface structure factor that we obtained agrees with computer simulations and theoretical predictions.

description: For each country is of great importance to collect the taxes that are used to cover its expenses, or for providing the basic functions of a state and meet specific needs of the general public. However, one of the most widespread financial indiscipline entities in the Republic of Serbia is just avoiding the payment of duties, which represent the public revenue (customs, different kinds of taxes, particularly excise taxes on goods and services, various taxes, levies and other fiscal obligations). In this way, not only violating the law, but can cause many negative consequences of illegal or unlawful status. In this paper we gave a presentation of the most common ways of avoiding paying taxes in our country and indicated the main characteristics of business in the area of “gray economy”. He also drew attention to the consequences of such behavior by the state and society. At the end of the work we have pointed out the basic characteristics of the crime of tax evasion, considering that we are talking about the criminal part of which occurs as a result of failure to meet obligations to pay taxes and other levies and also constitutes a criminal offense that dominated in the overall structure of economic crime in our country

description: Introduction. Depuis le 11 mars 2020, la Côte d’Ivoire est touchée par l’épidémie de coronavirus, déclarée ce même jour comme pandémie par l’OMS. Au 11 mars 2021, soit un an après la pandémie, la Côte d’Ivoire a notifié 36 824 cas de patients atteints de Covid-19 et parmi eux 211 sont décédés. Au 31 mai 2020, la Côte d’Ivoire avait déjà notifié 2 833 cas et 33 décès. À cette période, de fausses rumeurs circulaient en Afrique sur la mise en place d’essais cliniques sur des candidats vaccins. L’impact de ces rumeurs sur l’utilisation globale des services de santé devait être mesuré et notamment sur les centres de vaccination. Objectifs. L’objectif de cette étude était de déterminer les effets de la pandémie sur les activités des services de vaccination de l’Institut national d’hygiène publique. L’étude était basée sur les rapports d’activité de son centre de vaccination de Treichville à Abidjan, composé de quatre services : Centre des vaccinations internationales, Service de vaccination des collectivités, Centre antirabique, Unité de vaccination du Programme élargi de vaccination. Résultats. Au Centre des vaccinations internationales, les activités ont chuté d’environ 50 % en mars, de 86 % en avril et de 82 % en mai par rapport à 2018 et 2019. Pour les vaccinations communautaires, les activités ont diminué d’environ 26 % en mars et de 99 % en avril et mai. Au Centre de lutte contre la rage, ces diminutions sont estimées à 38 % en avril et à 45 % en mai. Les réductions les plus importantes concernent les vaccinations contre la fièvre jaune et les méningites. Conclusion. La baisse de la fréquentation des services de vaccination pourrait augmenter le risque de survenue d’épidémies notamment de fièvre jaune qui sont déjà récurrentes à Abidjan. Des mesures de sensibilisation et de rattrapage vaccinal devraient être entreprises et d’autres études devraient être menées pour déterminer l’impact de la pandémie sur les activités de vaccination.

description: Cette journée a pour but d’inciter les praticiens, les chercheurs, les décideurs publics et privés, économiques et politiques, à considérer et à mieux anticiper l’impact sous les tropiques des pollutions environnementales rurales et urbaines sur la santé humaine, animale, végétale, marine, et microbiologique : les conséquences de l’exposition à ces substances toxiques sont particulièrement néfastes quand elle est associée à des complexes pathogènes spécifiques des tropiques, à la pauvreté et au sous-développement. Il ne s’agit pas de dresser un catalogue de toutes les pollutions environnementales, mais de situer chaque polluant présenté dans une perspective écosystémique, pluridisciplinaire de santé publique et aussi individuelle (Une seule santé/One Health), en tenant compte des histoires, ressentis et représentations locales. Malgré leur importance, des sujets majeurs, comme les devenirs des matières plastiques non carbonisées, les perturbateurs endocriniens, ou les pollutions radioactives, ne seront pas traités faute de temps. Nous traiterons des conséquences des pollutions aériennes urbaines par les fumées de combustion des ordures, des moteurs, des foyers domestiques…, à partir de l’exemple d’écosystèmes urbains togolais et ivoiriens ; il sera aussi question des impacts des pollutions urbaines et agricoles sur la prolifération des moustiques, de dysplasies faciales chez des chimpanzés sauvages attribuées aux produits phytosanitaires utilisés dans les champs qu’ils ravagent, et de la chlordécone aux Antilles françaises ; seront abordés également les impacts sur la santé des populations vivant à proximité d’exploitations minières et pétrolières, industrielles et artisanales et plus particulièrement des pollutions par les métaux lourds (Hg, Pb…), associées aux exploitations aurifères. À côté des risques sanitaires proprement dits, les répercussions sociales, politiques, économiques, à l’échelon local, national et international seront évoquées, notamment au cours de trois tables rondes d’une trentaine de minutes organisées entre les intervenants de chaque session (« pollutions aériennes », « pollutions par pesticides et engrais », « pollutions minières et pétrolières ») et alimentées par les questions et réflexions écrites des participants.

description: Two complementary mechanisms are thought to shape social groups: homophily between agents and structural balance in connected triads. Here we consider $N$ fully connected agents, where each agent has $G$ underlying attributes, and the similarity between agents in attribute space (i.e., homophily) is used to determine the link weight between them. To incorporate structural balance we use a triad-updating rule where only one attribute of one agent is changed intentionally in each update, but this also leads to accidental changes in link weights and even link polarities. The link weight dynamics in the limit of large $G$ is described by a Fokker-Planck equation from which the conditions for a phase transition to a fully balanced state with all links positive can be obtained. This "paradise state" of global cooperation is, however, difficult to achieve requiring $G > O(N^2)$ and $p>0.5$, where the parameter $p$ captures a willingness to consensus. Allowing edge weights to be a consequence of attributes naturally captures homophily and reveals that many real-world social systems would have a subcritical number of attributes necessary to achieve structural balance.

Whither DDI - Status and Prospects in Canada
Creators: name: Bradley, Bill
Publisher: name: Zenodo
Year: 2007

description: The presentation summarizes a paper commissioned by Human Resources and Social Development Canada to examine the present status and future prospects of the Data Documentation Initiative (DDI) as a basis for improving the provision and exchange of policy-actionable data and knowledge in Canada. The paper takes the perspective of a major investor in the DDI, and is written in two parts. Part 1 provides an introduction to the DDI for researchers and knowledge workers. It describes the current state of the standard, its implementation in software tools, and the adoption of such tools in Canada's universities and governments. It introduces Version 3 and associated issues. Although there are some encouraging signs, the evidence suggests that the DDI is fragile, has not yet achieved much return on investment, and is taking on considerable risk. Part 2 introduces some of the difficulties in implementing standards for statistical metadata. It outlines the essential elements for a successful DDI: a)the standard; provision of metadata and content according to that standard, b) provision of sustainable, industrial-strength metadata management, web server, and 'killer' end-user applications to make it so, c) and close co-ordination among the elements to focus limited resources on the achievement of strategic goals. Part 2 provides an assessment of the status of the DDI for each element. The paper concludes that investments in the various components that comprise the DDI are asynchronous with the realities of the standard's overall implementation, take-up and payoffs. There appears to be almost no coordination between the elements, and little recognition among those working in each area of the interdependence of their efforts. The paper proposes that a meeting take place between key actors to initiate better coordination processes, and makes interim suggestions for action by each.

description: We calculate and resum a perturbative expansion of nuclear enhanced power corrections to the structure functions measured in deeply inelastic scattering of leptons on a nuclear target. Our results for the Bjorken $x$-, $Q^2$- and $A$-dependence of nuclear shadowing in $F_2^A(x,Q^2)$ and the nuclear modifications to $F_L^A(x,Q^2)$, obtained in terms of the QCD factorization approach, are consistent with the existing data. We demonstrate that the low-$Q^2$ behavior of these data and the measured large longitudinal structure function point to a critical role for the power corrections when compared to other theoretical approaches.

description: Phosphorene, a monolayer of bulk black phosphorus, is promising for light harvest owing to its high charge mobility and tunable direct band gap covering a broad spectral range of light. Here, via atomic-scale first-principles simulations, we report a ultrahigh activity of hydrogen evolution reaction (HER) of phosphorene originated from defective activation. Quantitative evaluation of the Gibbs free energy of the ad desorption of hydrogen (H) to from phosphorene (delta_GH) reveals that atomic vacancies and edges play a dominant role in activating the reaction. We find that the defective states, empty and well-localized around the defect core, are compensated by H species. This induces a proper hydrogen interaction complying with the thermoneutral condition of the free energy (delta_GH=0) comparable to platinum. Our findings of the highly activating defective states suggest the design of non-metal HER catalysts with structural engineering of earth-abundant phosphorus structures.

description: The rapid electrification of transportation, driven by stringent decarbonization targets and supportive policies, poses significant challenges for distribution system operators (DSOs). When numerous electric vehicles (EVs) charge concurrently, local transformers risk overloading - a problem that current tariff-based strategies do not adequately address. This paper introduces an aggregator-based coordination mechanism that shifts EV charging from congested to underutilized periods using a rule-based scheduling algorithm. Unlike conventional methods that depend on complex real-time pricing signals or optimization-heavy solutions, the aggregator approach uses a simple yet effective "laxity" measure to prioritize charging flexibility. To assess technical and economic viability, a multi-agent simulation was developed to replicate residential user behavior and DSO constraints under the use of a 400 kVA low-voltage transformer. The results indicate that overloads are completely eliminated with minimal inconvenience to users, whose increased charging costs are offset by the aggregator at an annual total of under DKK 6000 - significantly lower than the cost of infrastructure reinforcement. This study contributes by (i) quantifying the compensation needed to prevent large-scale overloads, (ii) presenting a replicable, computationally feasible, rule-based aggregator model for DSOs, and (iii) comparing aggregator solutions to costly transformer upgrades, underscoring the aggregator's role as a viable tool for future distribution systems.

description: Résumé Objectif. Dans le cadre d’une étude d’impact de la chimiothérapie préventive contre la filariose lymphatique au Burkina Faso, le Programme national de lutte contre les maladies tropicales négligées (PNMTN) a conduit une enquête d’évaluation de la transmission dans les districts sanitaires de Léo, Sapouy, Boromo et Dédougou. L’objectif principal était d’évaluer le niveau de transmission de la filariose lymphatique dans ces 4 districts sanitaires répartis en 2 unités d’évaluation (UE) (Boucle du Mouhoun 3 et du Centre-Ouest 2) après au moins 9 ans de traitement médicamenteux de masse. Méthodologie. Il s’est agi d’une enquête transversale à visée descriptive réalisée en milieu communautaire sur un échantillon d’enfants de 6 à 7 ans sélectionnés par sondage en grappe. Résultats. Sur 1649 enfants enquêtés dans l’UE Centre-Ouest 2, quatre étaient positifs au Filariasis Test Strip (FTS), soit une proportion de porteurs d’antigène filarien circulant (signant la présence de stades adultes vivant de Wuchereria bancrofti) de 0,24 %. Dans l’UE BMH3, aucun des 1716 enfants enquêtés n’était positif au FTS. Conclusion. Ces résultats montrent que la transmission de la filariose lymphatique est interrompue dans ces districts sanitaires, où les traitements de masse à l’albendazole et l’ivermectine peuvent donc être interrompus.

description: The rapid proliferation of consumer electronic devices with limited capabilities over the last decade has ushered in a remarkable era of growth, necessitating the establishment of a more robust computing, storage, and communication framework to ensure heightened security. This surge in consumer electronics has permeated diverse sectors such as communication, finance, entertainment, and other services, imposing a pressing need to adhere to stringent information security standards. The Gramm-Leach-Bliley Act, including the Financial Services Modernization Act and Federal Financial Institutions Examination Council, underscores the imperative of encrypting electronic customer information during transmission or storage on networks and systems vulnerable to unauthorized access.

As the consumer electronics landscape continues to expand, the integration of devices into the Internet of Things (IoT) poses a formidable challenge in devising security solutions capable of safeguarding the exchanged data. In the contemporary realm of digital communication networks, ensuring the privacy and security of transmitted data has emerged as an indispensable prerequisite for effective communication. Over time, there has been a concerted effort to explore data security schemes that furnish secure, real-time data storage across various applications, taking into account an array of potential attacks.

In this context, the focus has shifted towards the exploration and implementation of lightweight cryptography algorithms, particularly in the context of resource-constrained devices within the IoT. These lightweight cryptography algorithms serve as a crucial line of defense, mitigating security risks associated with devices operating under resource constraints. This paper delves into the evolving landscape of data security, emphasizing the significance of encryption protocols and the adoption of lightweight cryptography in addressing the unique challenges posed by the IoT ecosystem

description: We reconsider the construction of exponential fields in the quantized Liouville theory. It is based on a free-field construction of a continuous family or chiral vertex operators. We derive the fusion and braid relations of the chiral vertex operators. This allows us to simplify the verification of locality and crossing symmetry of the exponential fields considerably. The calculation of the matrix elements of the exponential fields leads to a constructive derivation of the formula proposed by Dorn/Otto and the brothers Zamolodchikov.
