Polylogarithmic-depth controlled-NOT gates without ancilla qubits.

Controlled operations are fundamental building blocks of quantum algorithms. Decomposing n-control-NOT gates (C(X)) into arbitrary single-qubit and CNOT gates, is a crucial but non-trivial task. This study introduces C(X) circuits outperforming previous methods in the asymptotic and non-asymptotic regimes.

Sparse Quantum State Preparation for Strongly Correlated Systems.

Quantum computing allows, in principle, the encoding of the exponentially scaling many-electron wave function onto a linearly scaling qubit register, offering a promising solution to overcome the limitations of traditional quantum chemistry methods. An essential requirement for ground state quantum algorithms to be practical is the initialization of the qubits to a high-quality approximation of the sought-after ground state. Quantum state preparation enables the generation of approximate eigenstates derived from classical computations but is frequently treated as an oracle in quantum information.

[Childhood sexual abuse: how important is the diagnosis to understand and manage sexual, anorectal and lower urinary tract symptoms].

Objective: To understand and manage the sequels of childhood sexual abuse on sexual, anorectal and lower urinary tract functions.

Material And Methods: Review of articles published in the Medline database, selected according to their scientific relevance and published guidelines on this subject together with our own experience.

Results: A history of sexual abuse is frequently found when assessing dysfunction or symptoms of the lower urinary tract.

Knee kinetic pattern during gait and anterior knee pain before and after rehabilitation in patients with patellofemoral pain syndrome.

Patellofemoral pain is likely due to compressive force acting on the patella related in turn to knee extension moment. The latter variable was assumed to be (i) reduced during short-distance free walking in case of patellofemoral pain syndrome and (ii) increased after therapeutic pain reduction. Peak knee extension moment at beginning of stance phase was recorded by three-dimensional gait analysis in 22 controls and in 23 patients with patellofemoral pain syndrome before and after rehabilitation of knee extensors and flexors to reduce the pain.

[Disabled elderly people waiting for institutionalization to a hospital ward: prospective study in the administrative district of Strasbourg (France)].

Objectives: Our aim was to estimate the number of non-satisfied instutionalization requests for inpatients and to describe the strategies elaborated to compensate for the waiting time.

Methods: This prospective follow-up study concerning all requests for institution admission for inpatients aged 75 years or older hospitalized in acute care and rehabilitation wards. Descriptive data were gathered throughout the social support process conducted during the hospitalization.

The impact of obesity on technical feasibility and postoperative outcomes of laparoscopic left colectomy.

Objective: To compare technical aspects and postoperative outcomes of laparoscopic left colectomy in obese and nonobese patients.

Summary Background Data: Obesity has been generally associated with increased surgical risk. The data regarding outcomes after laparoscopic colectomy in obese and nonobese patients are limited and quite controversial; however, most reports have suggested that obesity is associated with a greater technical difficulty as well as an increased risk for conversions and postoperative complications.

Bronchopulmonary aspergilloma: a reappraisal.

Background: Classically, most complications observed after operations for aspergilloma occurred in patients with sequelae of tuberculosis. Because the incidence of tuberculosis has declined over the past two decades, aspergilloma is expected to develop with increasing frequency in patients without previous tuberculosis. Therefore, our hypothesis was that operative outcome should have improved during the most recent years in comparison with our previous experience.

[Computer-assisted design and production of a femoral hip prosthesis].

The authors believe that a better design of prosthetic femoral stem might reduce the incidence of loosening. They have developed a method to make a prosthesis precisely adapted to a patient. Two X-Rays, one antero-posterior and one lateral view are taken.
