Such an approach first divides an observed signal into fixed-length segments, then performs {\\it segment-level} local diarization based on an EEND module, and merges the segment-level results via clustering to form a final global diarization result. The segmentation is done to limit the number of speakers in each segment since the current EEND cannot handle a large number of speakers. In this paper, we argue that such an approach involving the segmentation has several issues; for example, it inevitably faces a dilemma that larger segment sizes increase both the context available for enhancing the performance and the number of speakers for the local EEND module to handle. To resolve such a problem, this paper proposes a novel framework that performs diarization without segmentation. However, it can still handle challenging data containing many speakers and a significant amount of overlapping speech. The proposed method can take an entire meeting for inference and perform {\\it utterance-by-utterance} diarization that clusters utterance activities in terms of speakers. To this end, we leverage a neural network training scheme called Graph-PIT proposed recently for neural source separation.

A balanced optical microwave phase detector (BOMPD) is implemented using a balanced Mach-Zehnder modulator and is employed to discriminate the phase difference between the envelope of the optical pulses and the microwave oscillator. It is shown mathematically that the inherent nonlinear properties of BOMPD with respect to the microwave excitation amplitude can be used for interharmonic locking. The characteristic functions of the phase detector for interharmonic locking are derived analytically and are compared with the measurement results. An opto-electronic phase-locked loop (OEPLL) is demonstrated whose output frequency locks on interharmonics of the MLL repetition rate when an appropriate modulator bias and sufficient RF amplitude are applied. Thus, for the first time theory and experiment of reliable locking on interharmonics of the repetition rate of a MLL are presented.</jats:p>"}],"issue":"5","publication":"Optics Express","doi":"10.1364/oe.451894","language":[{"iso":"eng"}],"article_number":"7763","intvolume":"        30","publication_status":"published","date_updated":"2025-03-10T13:27:46Z","author":[{"id":"69233","first_name":"Meysam","last_name":"Bahmanian","full_name":"Bahmanian, Meysam"},{"id":"13256","last_name":"Kress","first_name":"Christian","full_name":"Kress, Christian"},{"orcid":"https://orcid.org/0000-0002-5950-6618","first_name":"J.

As the Nyquist signal has a rectangular bandwidth, it can be multiplexed in the wavelength domain without any guardband as a part of a Nyquist-WDM superchannel. These superchannels can be additionally multiplexed in space and polarization. Thus, the presented demonstration can open a new possibility for the detection of multidimensional parallel data signals with silicon photonics. No external pulse source is needed for the receiver, and frequency-time coherence is used to sample the incoming Nyquist signal with orthogonal sinc-shaped Nyquist pulse sequences. All parameters are completely tunable in the electrical domain. The feasibility of the scheme is demonstrated through a proof-of-concept experiment over the entire C-band (1530 nm–1560 nm), employing a 24 Gbaud Nyquist QPSK signal due to experimental constraints on the transmitter side electronics. However, the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can process Nyquist signals of 90 GHz optical bandwidth, suggesting a possibility to detect symbol rates up to 90 GBd in an integrated Nyquist receiver.</jats:p>","lang":"eng"}],"publication":"Optics Express","issue":"8","volume":30,"user_id":"13256","publisher":"Optica Publishing Group","_id":"34235","status":"public","project":[{"name":"PONyDAC: SPP 2111 - PONyDAC II - Präziser Optischer Nyquist-Puls-Synthesizer DAC","grant_number":"403154102","_id":"302"},{"name":"NyPhE: NyPhE - Nyquist Silicon Photonics Engine","_id":"299","grant_number":"13N14882"}],"citation":{"ieee":"A.

However, when experimenting with different problem formulations or when prototyping new algorithms, a major practical obstacle is the need to figure out derivatives of objective functions, especially when second‐order derivatives are required. Deriving and manually implementing gradients and Hessians is both time‐consuming and error‐prone. Automatic differentiation techniques address this problem, but can introduce a diverse set of obstacles themselves, e.g. limiting the set of supported language features, imposing restrictions on a program's control flow, incurring a significant run time overhead, or making it hard to exploit sparsity patterns common in geometry processing. We show that for many geometric problems, in particular on meshes, the simplest form of forward‐mode automatic differentiation is not only the most flexible, but also actually the most efficient choice. We introduce TinyAD: a lightweight C++ library that automatically computes gradients and Hessians, in particular of sparse problems, by differentiating small (tiny) sub‐problems. Its simplicity enables easy integration; no restrictions on, e.g., looping and branching are imposed. TinyAD provides the basic ingredients to quickly implement first and second order Newton‐style solvers, allowing for flexible adjustment of both problem formulations and solver details. By showcasing compact implementations of methods from parametrization, deformation, and direction field design, we demonstrate how TinyAD lowers the barrier to exploring non‐linear optimization techniques. This enables not only fast prototyping of new research ideas, but also improves replicability of existing algorithms in geometry processing. TinyAD is available to the community as an open source library.</jats:p>"}],"extern":"1","issue":"5","publication":"Computer Graphics Forum","volume":41,"user_id":"117512","_id":"60369","publisher":"Wiley","page":"113-124","status":"public","citation":{"ieee":"P.

The elements are guaranteed to be valid, i.e. defined by injective rational functions. The mesh is guaranteed to conform exactly, without geometric error, to arbitrary rational domain boundary and feature curves. The method generalizes the recent Bézier Guarding technique, which is applicable only to polynomial curves and elements. This generalization enables the accurate handling of practically important cases involving, for instance, circular or elliptic arcs and NURBS curves, which cannot be matched by polynomial elements. Furthermore, although many practical scenarios are concerned with rational functions of quadratic and cubic degree only, our method is fully general and supports arbitrary degree. We demonstrate the method on a variety of test cases.</jats:p>"}],"extern":"1","publication":"Computer Graphics Forum","issue":"5","type":"journal_article","department":[{"_id":"969"}],"date_created":"2025-06-25T08:56:35Z"},{"extern":"1","publication":"Computer Aided Geometric Design","department":[{"_id":"969"}],"type":"journal_article","date_created":"2025-06-25T08:44:09Z","intvolume":"        94","date_updated":"2025-07-14T12:47:12Z","publication_status":"published","publication_identifier":{"issn":["0167-8396"]},"author":[{"first_name":"Manish","last_name":"Mandad","full_name":"Mandad, Manish"},{"full_name":"Chen, Ruizhi","first_name":"Ruizhi","last_name":"Chen"},{"full_name":"Bommes, David","last_name":"Bommes","first_name":"David"},{"full_name":"Campen, Marcel","first_name":"Marcel","last_name":"Campen","orcid":"0000-0003-2340-3462","id":"114904"}],"year":"2022","title":"Intrinsic mixed-integer polycubes for hexahedral meshing","doi":"10.1016/j.cagd.2022.102078","language":[{"iso":"eng"}],"article_number":"102078","citation":{"mla":"Mandad, Manish, et al. “Intrinsic Mixed-Integer Polycubes for Hexahedral Meshing.” <i>Computer Aided Geometric Design</i>, vol. 94, 102078, Elsevier BV, 2022, doi:<a href=\"https://doi.org/10.1016/j.cagd.2022.102078\">10.1016/j.cagd.2022.102078</a>.","ama":"Mandad M, Chen R, Bommes D, Campen M.
