A precise knowledge of the sources of the arterial and neural supply of the sternohyoid (SH), sternothyroid (STM), and superior belly of omohyoid (OM) is of value to surgeons using the infrahyoid muscles in reconstruction procedures of the head and neck. This study was designed to define the anatomical bases of the variable sources of the arterial and neural supply of these muscles. Fourteen ca...

purpose: to determine anterior chamber depth (ac depth) changes during a 6 month period after phacoemulsification cataract surgery and foldable intraocular lens (iol) implantation. methods: in a cross-sectional study, 85 eyes of 85 patients were evaluated for ac depth and capsulo-rrhexis size one and six months after the procedure. results: patients included 44 male and 41 female subjects with ...

Time interleaved A/D converters (ADCs) can be used to increase the sample rate of an ADC system. However, a problem with time interleaved ADCs is that distortion is introduced in the output signal due to various mismatch errors between the ADCs. One way to decrease the impact of the mismatch errors is to introduce additional ADCs in the interleaved structure and randomly select an ADC at each s...

We introduce Action-Constrained Partially Observable Markov Decision Process (AC-POMDP), which arose from studying critical robotic applications with damaging actions. AC-POMDPs restrict the optimized policy to only apply feasible actions: each action is feasible in a subset of the state space, and the agent can observe the set of applicable actions in the current hidden state, in addition to s...

Matrix converter is basically direct three phase to three phase converter and it’s operation is based upon switching pattern of all nine switches, which are available in this converter. The output of ac converter is fed as the input of three phase induction motor. The performance of three phase matrix converter fed induction motor drive is analyzed by the switching pattern obtained by matrix co...

In calorimetry and particularly in heat capacity measurements, different characteristic relaxation time constants may perturb the experiment which cannot be considered at thermodynamic equilibrium. In this case, thermodynamics of irreversible processes has to be taken into account and the calorimetric measurements must be considered as dynamic. In a temperature modulated experiment, such as ac-...

BACKGROUND Acromioclavicular injuries are common in sports medicine. Surgical intervention is generally advocated for chronic instability of Rockwood grade III and more severe injuries. Various methods of coracoclavicular ligament reconstruction and augmentation have been described. The objective of this study is to compare the biomechanical properties of a novel palmaris-longus tendon reconstr...

A proposal for energy management in an off-grid photovoltaic pumping and irrigation system is presented and evaluated for a specific case study. The system is assumed to be based on off-the-shelf components (photovoltaic panels, battery banks, DC/AC converters, relays, submergible pumps, etc.), with a microcontroller-based energy management system, deciding when to disconnect the load from the ...

We evaluated the ingestion of anti-sheep erythrocyte (anti-E) IgG- and IgM-coated sheep erythrocytes by murine peritoneal macrophages exposed to cefodizime, a new semisynthetic cephalosporin, and other antibiotics. Cefodizime enhanced the ingestion of anti-E IgG-coated erythrocytes by peritoneal macrophages from CD-1 and BALB/c mice in a dose-dependent manner, but had no effect on uncoated or I...

There is controversy in the literature regarding a number of topics related to anterior cruciate ligament (ACL)reconstruction. The purpose of this article is to answer the following questions: 1) Bone patellar tendon bone (BPTB) reconstruction or hamstring reconstruction (HR); 2) Double bundle or single bundle; 3) Allograft or authograft; 4) Early or late reconstruction; 5) Rate of return to sp...
