Online Courts: Bridging the Gap Between Access and Justice

This article analyses the introduction of online court proceedings through the prism of access to justice. It distinguishes between the two major recent developments in terms of justice and court accessibility – ie the institutionalisation of alternative dispute resolution mechanisms and the expansion of online dispute resolution within public courts. Whilst both movements appear to be driven by similar theoretical forces, the practical adoption of fully online judicial proceedings constitutes a step towards a different direction, opening up new opportunities for attenuating the apparently intrinsic efficiency-fairness trade-off. Due to the unique features of digital technology, the emergence of state-provided online courts and tribunals for the resolution of minor civil disputes could significantly improve the efficiency of formal adversarial litigation processes, without the risk of sacrificing proper procedural protections. Overall, this article advocates that the balanced combination offered by online court systems, albeit not a panacea, may be translated into a potential enhancement of both ‘access’ and ‘justice’.

DETERMINATION OF THE 234U ISOTOPE CONTENT IN URANIUM-BEARING MATERIALS USING HIGH-RESOLUTION GAMMA SPECTROMETRY

The paper presents an overview of the research into the available non-destructive methods of determining the 234U isotope content in uranium-bearing materials. An alternative approach to a problem of detector calibration by the characteristic “intrinsic” efficiency is proposed. Certified reference uranium-bearing materials CRM 969 and CRM 146 (a range of 235U enrichments studied was 0.3…93%) were used as test samples, measurements were carried out with a wide-range energy detector based on the high-purity BeGe 3830 germanium (Canberra, USA) with 38 cm2 area and 3 cm thickness. An approach used for the “intrinsic” efficiency calibration for the 234U analysis permits to decrease the measurement error to 7.5% in the whole range of 235U enrichment (from 0.3 to 93%) and 234U concentrations (20 to 9800 µg/g). The proposed method does not demand standard samples for equipment calibration and does not depend on the physical (chemical) form of the investigated material and measurement geometry.

Symmetric and asymmetric cyclic controlled quantum teleportation via nine-qubit entangled state

In this paper, by utilizing a nine-qubit entangled state as a quantum channel, we propose new schemes for symmetric and asymmetric cyclic controlled quantum teleportation (CYCQT). In our proposed schemes, four participants Alice, Bob, Charlie and David teleport their unknown quantum states cyclically among themselves with the help of a controller Eve. No participants can reconstruct the original states sent from the respective senders without the permission of the controller. Also, by considering same nine-qubit entangled state as a quantum channel, we propose a generalized scheme for CYCQT of multi-qubit states. In contrast to the previous CYCQT schemes involving three communicators and a controller, there are four communicators and a controller in the proposed schemes. Also, compared with previous CYCQT schemes, our proposed CYCQT schemes require less consumption of quantum resource and the intrinsic efficiency of the generalized scheme increases with the increase of number of qubits in the information states.

Optical Data Transmission at 44 Tb/s with a Single Integrated Chip Source

We report world record high data transmission over standard optical fiber from a single optical source. We achieve a line rate of 44.2 Terabits per second (Tb/s) employing only the C-band at 1550nm, resulting in a spectral efficiency of 10.4 bits/s/Hz. We use a new and powerful class of micro-comb called soliton crystals that exhibit robust operation and stable generation as well as a high intrinsic efficiency that, together with an extremely low spacing of 48.9 GHz enables a very high coherent data modulation format of 64 QAM. We achieve error free transmission across 75 km of standard optical fiber in the lab and over a field trial with a metropolitan optical fiber network. This work demonstrates the ability of optical micro-combs to exceed other approaches in performance for the most demanding practical optical communications applications.
