The Quantum approximate optimization algorithm (QAOA) is a quantum-classical hybrid algorithm aiming to produce approximate solutions for combinatorial optimization problems. In the QAOA, the quantum part prepares a quantum parameterized state that encodes the solution, where the parameters are optimized by a classical optimizer. However, it is difficult to find optimal parameters when the quantum circuit becomes deeper. Hence, there is numerous active research on the performance and the optimization cost of QAOA. In this work, we build a convolutional neural network to predict parameters of depth QAOA instance by the parameters from the depth QAOA counterpart. We propose two strategies based on this model. First, we recurrently apply the model to generate a set of initial values for a certain depth QAOA. It successfully initiates depth 10 QAOA instances, whereas each model is only trained with the parameters from depths less than 6. Second, the model is applied repetitively until the maximum expected value is reached. An average approximation ratio of 0.9759 for Max-Cut over 264 Erd\H{o}s-R\'{e}nyi graphs is obtained, while the optimizer is only adopted for generating the first input of the model.

Visual speech (i.e., lip motion) is highly related to auditory speech due to the co-occurrence and synchronization in speech production. This paper investigates this correlation and proposes a crossmodal speech co-learning paradigm. The primary motivation of our cross-modal co-learning method is modeling one modality aided by exploiting knowledge from another modality. Specifically, two cross-modal boosters are introduced based on an audio-visual pseudo-siamese structure to learn the modality-transformed correlation. Inside each booster, a max-feature-map embedded Transformer variant is proposed for modality alignment and enhanced feature generation. The network is co-learned both from scratch and with pretrained models. Experimental results on the LRSLip3, GridLip, LomGridLip, and VoxLip datasets demonstrate that our proposed method achieves 60% and 20% average relative performance improvement over independently trained audio-only/visual-only and baseline fusion systems, respectively.

Japanese firms have historically followed a country-specific model of corporate governance. Yet, Japan has had to adapt its corporate model over the last 30 years, along with the transformation of distinctive characteristics of Japanese capitalism in the same period. We review the historical evolution of Japanese corporate governance over the last three decades with a specific emphasis on the changes in the capital structure of major companies and the efforts to correct ineffective board of directors monitoring. By doing this, we investigate to what extent specific Japanese corporate governance features may explain the nation’s economic situation over this period. Thereby, we try to clarify the influences that have presided over recent corporate governance reforms in Japan despite the existence of managerial failures and corporate scandals. This paper places itself into the debate over the diversity of capitalism as it portrays the specificities, differences, and converging trends of Japanese corporate governance practices.

Abstract The iconography of the martyrs of Japan is often linked to that of the Twenty-Six Martyrs of Nagasaki. This group of mostly Franciscans was crucified in 1597 and beatified in 1627, and also included three Jesuits. The Society of Jesus, however, did not emphasize these martyrs in their engravings and representations of the victims of their Japanese mission especially before their beatification. The close study of two major works, Nicolas Trigault’s History of the Martyrs of Japan (Latin, 1623; French, 1624) and the famous Imago primi saeculi (1640), reveals how text and image combine to generate a different discourse of martyrdom that centered on sacrificial fire rather than death on the cross. Although the first three beatified martyrs were never forgotten, the Imago in particular foregrounds another Jesuit martyr, Carlo Spinola, whose prominent family had played an important role in that work’s creation.

A high-precision hypernuclear experiment has been performed at the Mainz Microtron (MAMI) to determine the hypertriton {\Lambda} binding energy via decay-pion spectroscopy. A key element of this measurement is an accurate calibration of the magnetic spectrometers with the MAMI beam. For such an absolute calibration with small statistical and systematic uncertainties the undulator light interference method will be applied. In this contribution the basic principle of this method is discussed and the analysis status of the measured synchrotron radiation spectra is presented Comment: The 13th Biennial Conference on Classical and Quantum Relativistic Dynamics of Particles and Fields (IARD22)

Gender is a hot topic in the field of human-computer interaction (HCI). Work has run the gamut, from assessing how we embed gender in our computational creations to correcting systemic sexism, online and off. While gender is often framed around women and femininities, we must recognize the genderful nature of humanity, acknowledge the evasiveness of men and masculinities, and avoid burdening women and genderful folk as the central actors and targets of change. Indeed, critical voices have called for a shift in focus to masculinities, not only in terms of privilege, power, and patriarchal harms, but also participation, plurality, and transformation. To this end, I present a 30-year history of masculinities in HCI work through a scoping review of 126 papers published to the ACM Human Factors in Computing Systems (CHI) conference proceedings. I offer a primer and agenda grounded in the CHI and extant literatures to direct future work. Comment: 12 pages
