Abstract

A key challenge in realizing fault-tolerant quantum computers is circuit optimization. Focusing on the most expensive gates in fault-tolerant quantum computation (namely, the T gates), we address the problem of T-count optimization, i.e., minimizing the number of T gates that are needed to implement a given circuit. To achieve this, we develop AlphaTensor-Quantum, a method based on deep reinforcement learning that exploits the relationship between optimizing T-count and tensor decomposition. Unlike existing methods for T-count optimization, AlphaTensor-Quantum can incorporate domain-specific knowledge about quantum computation and leverage gadgets, which significantly reduces the T-count of the optimized circuits. AlphaTensor-Quantum outperforms the existing methods for T-count optimization on a set of arithmetic benchmarks (even when compared without making use of gadgets). Remarkably, it discovers an efficient algorithm akin to Karatsuba's method for multiplication in finite fields. AlphaTensor-Quantum also finds the best human-designed solutions for relevant arithmetic computations used in Shor's algorithm and for quantum chemistry simulation, thus demonstrating it can save hundreds of hours of research by optimizing relevant quantum circuits in a fully automated way.

Abstract

The urinary metabolic pattern after administration of the radiolabeled non-provitamin A carotenoid canthaxanthin was investigated in rats. In the rather complex HPLC urinary metabolic pattern a fraction was found which was conjugated. Deconjugation of the polar conjugates with glusulase, purification of the metabolite with HPLC and identification with GC-MS and NMR revealed that it was 3-hydroxy-4-oxo-7,8-dihydro-beta-ionone. This structure was confirmed by comparisons with HPLC retention times, UV/VIS- and NMR-spectroscopy and GC-MS of the synthesized compound.

Abstract

Objective: To assess the effectiveness of the pharmacotherapeutic circle (PTC), a general practitioner (GP) prescribing-improvement programme to enhance prescribing quality and reduce drug costs.Design: Combined pre- and post-intervention time-series design using an internal comparison of subgroups and an external comparative control.Setting: Small discussion groups meeting 8 times over 18 months.Participants: 79 GPs exceeding the mean drug costs/patient of all Hessian physicians by > or = 40%; 10 moderators.Interventions: Peer-review feedback of prescription patterns based on guidelines targeting 3 suboptimal prescribing areas: drug prescriptions lacking evidence-based efficacy (target A); presumptive prescribing habits (target B); and underprescribing of new, effective therapies (target C).Main Outcome Measures and Results: Significant decreases in prescription rates for target A drugs were recorded for varicose vein medications (p = 0.006), peripheral vasodilators (p = 0.0001) and topical antirheumatics (p = 0.0145), but not for prokinetics/enzymes/digestives. Prescribing of target B drugs such as benzodiazepines and nonsteroidal anti-inflammatory drugs declined markedly (p = 0.0019 and 0.0014, respectively). Target C drug prescriptions such as for opioids and proton pump inhibitors were not significantly increased. Highly significant reductions in prescription costs were observed for target A and B drugs, irrespective of whether GPs were stratified into high, medium or low prescribers. When mean prescribing costs for PTC participants were compared with those of a control group comprising 8000 GPs over a 21-month period, PTC GPs decreased their costs by 2%, whereas drug costs for all Hessian physicians rose by 10%.Conclusions: PTCs appear to be an effective method to optimise the quality of drug prescribing and reduce drug costs.

46. The influence of temperature on some physical properties of dental composites.

Subjects
*DENTAL resins, *THERMODYNAMICS, *THERMAL analysis, *DENTAL fillings, *POLYMERIZATION, *INFRARED heating
Abstract

In this study diametral tensile strength and microhardness of composites were investigated in relation to various temperatures during curing, it has been demonstrated that temperatures elevated up to 60°C can improve the mechanical properties considerably. Also the stability of the resin system in aggressive environments was improved due to more efficient cross-linking. Thermal analysis of the material showed an endothermic reaction between 60 and 70°C that is believed to be responsible for the initiation of the extra cross-linking. Heating of composite fillings during clinical use is suggested. [ABSTRACT FROM AUTHOR]

47. The curing pattern of photo-initiated dental composites.

Subjects

Abstract

In this study the curing of photo-initiated composites was investigated. After irradiation, the material in an experimental cavity could be divided into three zones: zone A which showed physical properties comparable to those of chemical initiated composites, zone B which was markedly softer than the first one, and zone C which showed no signs of curing at all. The location of the zones was dependent on the energy of the u.v. radiation, the exposure time, the storage time, and the storage conditions. The uncured material of zone C showed no tendency to set. The clinical implications of the observations are discussed. [ABSTRACT FROM AUTHOR]

48. Structural changes in composite surface material after dry polishing.

Abstract

The purpose of this study was to investigate the properties of composite materials that bad been heated to temperatures which may occur during dry polishing. Bulk composite material was submitted to thermal analysis from R.T. to 200°C. Two distinct stages of thermal reaction in this range could be identified. One at approximately 70°C, which could be related to a further initiating of unreacted groups, and one above 100°C, which could be related to the glass transition. The glass transition was also observed microscopically. Hardness measurements were carried out on the warm material at different temperatures as well as on the material being cooled down to R.T. With temperature rise, a continuous increase in hardness and abrasion resistance could be demonstrated. The observed phenomena for bulk material are related to the properties measured on dry polished surfaces. [ABSTRACT FROM AUTHOR]
