Syndrome decoding by quantum approximate optimization [PDF]
Quantum Inf Process 23, 368 (2024), 2022 The syndrome decoding problem is known to be NP-complete. The goal of the decoder is to find an error of low weight that corresponds to a given syndrome obtained from a parity-check matrix. We use the quantum approximate optimization algorithm (QAOA) to address the syndrome decoding problem with elegantly-designed reward Hamiltonians based on both ...

Adjuvant pharmacological strategies for the musculoskeletal system during long‐term space missions
British Journal of Clinical Pharmacology, EarlyView., 2023 Abstract Despite 2 h of daily exercise training, muscle wasting and bone loss are still present after 6‐month missions to the international space station. Some crew members lose bone much faster than others. In preparation for missions to the Moon and Mars, space agencies are therefore reviewing their countermeasure portfolios.

Calibration of syndrome measurements in a single experiment [PDF]
New J. Phys. 26 123010 (2024), 2023 Quantum error correction can reduce the effects of noise in quantum systems, e.g. in metrology or most notably in quantum computing. Typically, this requires making measurements that provide information about the errors that have occurred in the system.

Quantum error correction with higher Gottesman-Kitaev-Preskill codes: minimal measurements and linear optics [PDF]
, 2021 We propose two schemes to obtain Gottesman-Kitaev-Preskill (GKP) error syndromes by means of linear optical operations, homodyne measurements and GKP ancillae. This includes showing that for a concatenation of GKP codes with a $[n,k,d]$ stabilizer code only $2n$ measurements are needed in order to obtain the complete syndrome information, significantly

PCONet: A Convolutional Neural Network Architecture to Detect Polycystic Ovary Syndrome (PCOS) from Ovarian Ultrasound Images [PDF]
arXiv, 2022 Polycystic Ovary Syndrome (PCOS) is an endrocrinological dysfunction prevalent among women of reproductive age. PCOS is a combination of syndromes caused by an excess of androgens - a group of sex hormones - in women. Syndromes including acne, alopecia, hirsutism, hyperandrogenaemia, oligo-ovulation, etc. are caused by PCOS. It is also a major cause of

A potential biomarker of androgen exposure in European bullhead (Cottus sp.) kidney [PDF]
Fish Physiology and Biochemistry 39, 3 (2013) 573-580, 2014 The aim of this study was to identify a signal that could be used as an androgen exposure indicator in the European bullhead (Cottus sp.). For this purpose, the ultra-structure of the kidney was characterized to identify normal structure of this organ, and histological changes previously described in the kidney of breeding male bullheads were ...

Mapping Surface Code to Superconducting Quantum Processors [PDF]
arXiv, 2021 In this paper, we formally describe the three challenges of mapping surface code on superconducting devices, and present a comprehensive synthesis framework to overcome these challenges. The proposed framework consists of three optimizations. First, we adopt a geometrical method to allocate data qubits which ensures the existence of shallow syndrome ...

On the Use of Shor States for the [7,1,3] Quantum Error Correcting Code [PDF]
PRA 86, 052336 (2012), 2011 We explore the effect of Shor state construction methods on logical state encoding and quantum error correction for the [[7,1,3]] Calderbank-Shor-Steane quantum error correction code in a nonequiprobable error environment. We determine the optimum number of verification steps to be used in Shor state construction and whether Shor states without ...

Emerging trends in the management of non‐obstructive azoospermia
UroPrecision, EarlyView.Abstract Ten percent of infertile males have azoospermia, classified into obstructive and nonobstructive types, which require specific medical or surgical treatments. In nonobstructive azoospermia, advancements in microsurgery allow for effective sperm retrieval in about half of cases.

Genomic technologies and the diagnosis of 46, XY differences of sex development
Andrology, EarlyView.Abstract Differences/disorders of sex development can be caused by disruptions to the molecular and cellular mechanisms that control development and sex determination of the reproductive organs with 1:100 live births affected. Multiple genes are associated with 46, XY differences/disorders of sex development that can cause varying clinical phenotypes ...
