TOKYO and CAMBRIDGE, Mass., August 25, 2025 - (JCN Newswire via SeaPRwire.com) - Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, “Eisai”) and Biogen Inc. (Nasdaq: BIIB, Corporate headquarters: Cambridge, Massachusetts, CEO: Christopher A. Viehbacher, “Biogen”) announced today that the anti-amyloid beta(AB) monoclonal antibody “LEQEMBI®” has been launched in Austria on August 25, 2025 and will be launched in Germany on September 1, 2025. LEQEMBI received the European Commission (EC) approval in April 2025 as the first therapy that targets an underlying cause of Alzheimer’s disease (AD). It is indicated for the treatment of adult patients with a clinical diagnosis of mild cognitive impairment(MCI) and mild dementia due to AD ( collectively referred to as early AD) who are apolipo protein E 4(ApoE 4*) non-carriers or heterozygotes with confirmed amyloid pathology.1 Germany and Austria will mark the first launches in the EU.Following the EC approval, Eisai has been collaborating with the regional and local healthcare authorities to implement the mandatory authorisation requirements ahead of launch. The required controlled access program** is now in place in Austria and Germany, enabling the launch in these first two EU countries. AD is a progressive, relentless disease with AB and tau as hallmarks. AD progresses in stages that increase in severity over time, and each stage of the disease presents different challenges for those living with AD and their care partners. There is a significant unmet need for new treatment options that slow the progression of AD by initiating therapy from its early stage and continuing it in order to reduce the overall burden on people affected by AD and society. Only LEQEMBI fights AD in two ways - targeting both amyloid plaque and protofibrils***, which can impact tau downstream.In the Clarity AD clinical trial, the primary endpoint was the global cognitive and functional scale, Clinical Dementia Rating – Sum of Boxes (CDR-SB).1 Treatment with lecanemab (n=757), in the EU indicated population (ApoE 4 non-carriers or heterozygotes, measured by controlled-based multiple imputation), reduced clinical decline on CDR-SB by 31% at 18 months compared to placebo (n=764).1In the EU indicated population (ApoE 4 non-carriers or heterozygotes) (n=757), the most common adverse reactions were infusion-related reaction (26%), ARIA-H (13%), headache (11%) and ARIA-E(9%). Symptomatic ARIA-E occurred in 2% of participants. Symptomatic ARIA-H occurred in 0.8% of patients.1Eisai serves as the lead for lecanemab’s development and regulatory submissions globally with both Eisai and Biogen co-commercializing and co-promoting the product and Eisai having final decision making authority. In the EU (excluding the Nordic countries), Eisai and Biogen will co-promote the medicine, with Eisai distributing the product as the Marketing Authorization Holder.For more details, please visit: https://www.eisai.com/news/2025/pdf/enews202557pdf.pdf Copyright 2025 JCN Newswire via SeaPRwire.com.

Tokyo and Kawasaki, Japan, August 25, 2025 - (JCN Newswire via SeaPRwire.com) - Shibaura Institute of Technology (Associate Professor Takuya Otani, Faculty of System Science and Engineering [Human Robot System Laboratory]), Waseda University (Professor Atsuo Takanishi, Faculty of Science and Engineering), and Fujitsu Limited today announced the development of an innovative method for efficiently controlling robot posture using quantum computing technology. This new approach facilitates the efficient and accurate calculation of inverse kinematics, i.e., determining joint angles from a target end-effector position, for multi-joint robots by leveraging qubit-based position representation and quantum entanglement. Verification using Fujitsu's quantum simulator achieved up to a 43% error reduction with fewer calculations compared to conventional methods. The effectiveness of quantum entanglement was also confirmed through an experiment carried out on the 64-qubit quantum computer jointly developed by RIKEN and Fujitsu.By expressing the orientation and position of each robot link as a qubit, and by replicating the structural influence of parent joint movements on child joints through quantum entanglement, the number of necessary calculations was significantly reduced compared to conventional classical methods. As quantum computing advances towards practical application, this development is expected to contribute substantially to the creation of next-generation robots that demand real-time control and complex operational capabilities.Quantum technology breakthrough for complex robot posture calculationIn robot posture control, calculating inverse kinematics is crucial. For robots with multiple joints, the possible angle combinations are numerous, requiring iterative calculations to minimize the discrepancy from the target position and resulting in a high computational load. For a full-body multi-joint model with 17 joints, equivalent to the number of joints in the human body, the number of possible calculations required are too vast to be solved directly. A common approach has been to perform motion calculations with an approximated 7 joints, but this limits the smoothness of movement.In this research, a new method leveraging the power of quantum computing has been proposed to address these challenges. The orientation and position of each robot part (link) are represented by qubits, and forward kinematics, i.e., calculation of end-effector position from joint angles, is carried out using quantum circuits. Inverse kinematics calculations are performed on classical computers, achieving efficient posture control through a hybrid quantum-classical approach.Improved convergence speed and accuracy with quantum entanglementFurthermore, by introducing quantum entanglement, the structure where the movement of parent joints naturally influences child joints is reproduced on the quantum circuit. This significantly improved the convergence speed and accuracy of inverse kinematics calculations. In addition, a trial calculation showed that motion calculations for a full-body multi-joint model with 17 joints can be executed in approximately 30 minutes.Expected applications in humanoid and multi-joint robotsThis method can express the posture of multi-joint robots with a small number of qubits, making it implementable even in current noise intermediate-scale quantum (NISQ) computers. In the future, this technology could be applied to real-time control of humanoid robots and multi-joint manipulators, obstacle avoidance, and energy optimization. Further performance improvements are also anticipated through combination with advanced quantum algorithms such as quantum Fourier transform.Research paper detailsAuthors:- Takuya Otani, Shibaura Institute of Technology, Faculty of System Science and Engineering- Atsuo Takanishi, Waseda University, Faculty of Science and Engineering- Nobuyuki Hara, Fujitsu Limited- Yutaka Takita, Fujitsu Limited- Koichi Kimura, Fujitsu LimitedTitle: Quantum computation for robot posture optimizationJournal: Scientific Reports, Nature PortfolioDOI:10.1038/s41598-025-12109-0About Shibaura Institute of Technology (SIT), JapanShibaura Institute of Technology (SIT) is a private university with campuses in Tokyo and Saitama.

Tokyo, Japan, August 22, 2025 - (JCN Newswire via SeaPRwire.com) — NEC Corporation (NEC; TSE: 6701) today announced the development of an optical fiber sensing technology to monitor road conditions and accurately predict sudden traffic congestion in real time. By collecting data from existing optical fiber communications cables and analyzing real-time traffic flow data using a proprietary AI model, NEC has reduced prediction errors by 80% compared to conventional methods.This technology enables effective traffic control, including the arrangement of detour routes, thereby contributing to the resolution of societal challenges such as logistics issues and CO2 emissions.Technology OverviewTraffic congestion is a significant social issue, threatening safety and causing substantial economic losses. In particular, congestion on expressways—the backbone of many logistics networks—has a significant economic impact. Addressing this issue requires real-time understanding of road conditions for both immediate congestion mitigation and proactive avoidance, as well as highly accurate congestion prediction based on up-to-date data.Current monitoring approaches primarily rely on point-based instruments, including cameras and loop detectors, as well as probe vehicle data (*1). However, both have limitations: the former is costly to install and maintain over entire road networks, and the latter only provides data when equipped vehicles pass by specific receiver points, limiting real-time and continuous coverage. Moreover, existing congestion prediction models heavily rely on long-term historical data, making it difficult to capture the emergence and propagation of sudden, unexpected congestion patterns.To address these challenges, NEC has developed a technology that utilizes optical fiber cables—originally installed for communications purposes alongside roads—as extensive, distributed sensors for collecting real-time, continuous traffic flow data across entire routes. NEC’s unique AI-powered model then provides real-time, high-precision predictions regarding the development and clearance of sudden congestion.Technical FeaturesNEC has developed a data assimilation algorithm that combines advanced model parameter optimization and data adapting techniques, enabling accurate simulations of real-time traffic flow using comprehensive data collected along the entirety of roadways.Model Parameter Optimization AlgorithmNEC has created an algorithm to optimize theoretical model parameters—such as driver behaviors (e.g. inter-vehicle distance adjustment)—so that simulations faithfully reproduce observed traffic flow data for entire road segments.Data Adaptation AlgorithmAn advanced algorithm converts diverse traffic flow data, including "average speed" and individual vehicle "position/speed," into formats compatible with simulation inputs. This makes it possible to set the initial conditions for simulations based on comprehensive traffic flow data obtained on entire routes, significantly enhancing the reliability of simulation outputs.Through these innovations, NEC has confirmed—using real-world data—that travel time prediction errors (a key indicator for congestion forecasting) can be reduced by approximately 80% compared to the existing method that relies on cross-sectional data from point sensors such as cameras. NEC is further advancing the realization of a dynamic road digital twin that enables real-time, network-wide traffic monitoring, the prediction of congestion evolution, and optimization of responsive measures. Real-world trials are currently underway in close collaboration with road authorities, with the goal of practical deployment by fiscal 2026.This technology was developed using data provided by Central Nippon Expressway Company Limited (NEXCO CENTRAL) and was presented at the Transportation Research Board 104th Annual Meeting (*2). NEC will also present a related paper at the 31st ITS World Congress in Atlanta, Georgia, USA, focused on enhancing the accuracy of traffic flow monitoring on expressways (*3).(*1)A system that automatically collects driving data—such as the location and speed of vehicles equipped with onboard units—using roadside sensors installed at intervals ranging from several to tens of kilometers.(*2)Presentation ID TRBAM-25-01491, "A Novel Approach to Real-Time Short-Term Traffic Prediction based on Distributed Fiber-Optic Sensing and Data Assimilation with a Stochastic Cell-Automata Model," presented at the Artificial Intelligence–Based Solutions for Traffic Modeling and Control.(*3)Session ID: PS31 Transportation Systems: Traffic Management and Operations, Next-Generation Traffic Management Approaches Title: TSE (Traffic State Estimation) in Congestion to Extend the Applicability of DFOSAbout NEC CorporationThe NEC Group leverages technology to create social value and promote a more sustainable world where everyone has the chance to reach their full potential.
