Abstract:
Experimental exploration of equipment for stereotactic functional neurosurgery based on heating induced by radio-frequency current is most often carried out prior to surgery in order to secure a correct function of the equipment. The experiments are normally conducted in an experimental model including an albumin solution in which the treatment electrode is submerged, followed by a heating session during which a protein clot is generated around the electrode tip. The clot is believed to reflect the lesion generated in the brain during treatment. It is thereby presupposed that both the thermal

These patients are in need of cure or else they will develop metastatic disease. NRG/RTOG 9601 (WU Shipley, N Eng J Med 2017) identified a survival benefit from the addition of androgen receptor (AR) inhibition to SRT that was most prominent in men with high-risk features.

Abstract:
Deep Neural Networks (DNNs) have made massive progress in many fields and deploying DNNs on end devices has become an emerging trend to make intelligence closer to users. However, it is challenging to deploy large-scale and computation-intensive DNNs on resource-constrained end devices due to their small size and lightweight. To this end, model partition, which aims to partition DNNs into multiple parts to realize the collaborative computing of multiple devices, has received extensive research attention.

Abstract:
Faced with the dual pandemics of obesity and type 2 diabetes mellitus, heath care providers require a broad array of treatment options. Diet, exercise, and medications remain the cornerstones of type 2 diabetes therapy, but long-term results with lifestyle modifications can be disappointing, and, despite an ever-increasing armamentarium of pharmacotherapeutics, adequate glycaemic control often remains elusive. Moreover, most diabetes medications promote weight gain, and using them to achieve tight glycaemic control introduces a proportionate risk of hypoglycaemia. In cases where behavioural/pharmacological strategies prove insufficient, gastrointestinal surgery offers powerful alternatives for obesity and type 2 diabetes treatment (Fig. 13.4.5.1). Among severely obese patients, bariatric operations cause profound, sustained weight loss, ameliorating obesity-related comorbidities and reducing long-term mortality (1–4). Operations involving intestinal bypasses exert particularly dramatic antidiabetes effects. For example, approximately 84% of obese patients with type 2 diabetes experience diabetes remission after a Roux-en-Y gastric bypass (RYGB), maintaining euglycaemia off diabetes medications for at least 14 years (1, 5–8). Mounting evidence indicates that these effects result not only from weight loss, but also from weight-independent antidiabetic mechanisms (9). Whereas diabetes is traditionally viewed as a relentless disease in which delay of end-organ complications is the major treatment goal, gastrointestinal surgery offers a novel endpoint: complete disease remission. Consequently, conventional bariatric procedures and experimental gastrointestinal manipulations are being used worldwide to treat type 2 diabetes in association with obesity, and, increasingly, among less obese or merely overweight patients (8). Gastrointestinal surgery also offers valuable research opportunities to improve knowledge of diabetes pathogenesis and help develop less invasive procedures and novel pharmaceuticals. This chapter discusses the effects of gastrointestinal operations on type 2 diabetes, and focuses on potential antidiabetic mechanisms that mediate those effects.

Abstract:
La finalidad de este proyecto es diagnosticar, cómo se encuentra la situación actual de la Universidad Tecnológica en torno al clima laboral modificado por la micropolítica. Actualmente existen tres grupos, conformados por dos sindicatos, y los empleados no sindicalizados; dichos grupos coinciden en esperar cambios positivos en la Institución. Por otra parte, la lucha de poderes entre la Autoridad y el Sindicato Principal, los diferentes grupos de choque que existen, el nacimiento de un nuevo sindicato bajo el ala de la autoridad, hace que se haga más tensa la vida laboral, surgen entonces, las siguientes preguntas: ¿Cómo influyen los sindicatos en el clima organizacional de la Institución?, ¿qué tanto poder e influencia pueden experimentar las autoridades para lograr desequilibrar al personal?. Los cuestionamientos anteriores, nos inducen a pensar que la dinámica organizacional de la Universidad son un reflejo de la micropolítica, entendiéndose como una variable que refleja cómo es que los sujetos integrantes de la organización utilizan estrategias para influir sobre los otros miembros de la organización a través del ejercicio del poder que se refleja en la vida de la Institución, y que trasciende los espacios institucionales formales generando conflictos, propiciando o dificultando las negociaciones generando grupos de interés, etc. Desde un punto de vista metodológico la investigación es de tipo documental-exploratoria-descriptiva, se aplicó una encuesta, cuyo alfa de cronbach fue de 0.941, que indica que el instrumento diseñado es confiable. Se encontró la existencia de micropolítica en la Institución, reflejada en un 83.9% de los trabajadores consideran que se debe cambiar la politización de los dirigentes sindicales para mejorar las relaciones laborales. Por otra parte, la conformación de grupos internos por parte de la autoridad fue considerada por el 80.7% de los trabajadores como un factor que menoscaba las relaciones laborales.

A lo largo de la historia la sociedad ha experimentado, permanentemente, situaciones de confrontación de intereses que han dado origen a conflictos, los cuales, desde la teoría sociológica, son considerados como situaciones inherentes al ser humano y motores del cambio social. Como una alternativa para su resolución, el Estado colombiano ha implementado los Mecanismos Alternativos de Solución de Controversias, considerados como una forma de justicia complementaria de la estatal, cuya implementación persigue dos importantes finalidades: la participación de la sociedad en la solución de sus conflictos y la descongestión del aparato jurisdiccional.Dichas herramientas jurídicas han sido concebidos, además, como una forma de acabar con la judicialización del conflicto y, en consecuencia, de restaurar los tejidos sociales, lo que se logra cuando las partes involucradas, de manera voluntaria, deciden poner fin a su controversia haciendo uso de su autonomía privada, logrando así el restablecimiento de las relaciones que se han deteriorado y la consolidación de relaciones futuras entre los miembros de la sociedad. De allí la importancia de conocer el contexto donde surge la justicia informal, los mecanismos alternativos con los que cuenta el País, y el fundamento constitucional y legal que los soportan.

Abstract:
This final chapter introduces a few tissue engineering systems that either have been used clinically or are rapidly approaching clinical use for cartilage, skin, and nerve repair. Some of the elements of each tissue engineering system are presented, together with references to the primary literature. The first example involves engineering of a tissue with an important mechanical function: cartilage. The general approach described for cartilage has been attempted in other structural tissues such as bone, tendon, and skin; there are important common elements among these tissue engineering systems. One common underlying theme, which is emphasized in the first example, is the use of a material as a scaffold for the ingrowth, proliferation, and function of cells, which differentiate into mature functional cells. After being introduced to this first example and provided with an outline of some experimental results, the reader is then presented with a series of questions: some are intended to stimulate discussion in the classroom, while others can be used as homework assignments or as the basis for independent projects. The main objective of these exercises is to assimilate information from previous chapters and apply it in a situation with clinical application: cartilage tissue engineering. The second and third examples involve tissue-engineered skin and repair of nerves lost to disease or trauma. No questions are provided with these examples, but the reader is encouraged to identify the connections to material in the preceding chapters. One of the first tissue engineering products available to patients is Carticel1®, which uses autologous cultured chondrocytes for the repair of cartilage defects in the femoral condyle (spirally curved prominences on the end of the femur that is involved in the knee joint). The procedure has several phases: first, a pea-sized biopsy of healthy knee cartilage is obtained. This tissue is expanded in vitro to obtain a large number of cultured cells that are all derived from the patient. In a second procedure, a surgeon prepares the transplant site by removing diseased tissue and preparing the defect (in the clinical trials of this product, the defect had a cross-sectional area of &lt;1 to 20 cm2, with 90% of the defects &lt;10 cm2).

Abstract:
In this paper, the design of disposable 3D printed surgical end-effectors for robotic lumbar discectomy is presented. Discectomy is the surgery to remove the herniated disc material that is pressing on a nerve root or spinal cord. This surgery is performed to relieve pain or numbness caused by the pressure on the nerve. The limited workspace of the spine (&lt; 27 cm3) results in challenging design requirements for surgical instruments. We propose a new cannula-based robotic lumbar discectomy procedure that can accommodate multiple articulated tools in the workspace at the same time and can be

Abstract:
Endovascular AAA repair has evolved since its inception in the late 1980s to become an accepted alternative to open surgery. This minimally invasive approach involves inserting a collapsed stent-graft through the vasculature to the AAA location and allowing it to expand to form a new conduit for blood flow [1]. EVAR carries lower operative risk than the traditional method and recovery times are significantly lower. It has been performed with considerable success in octogenarians and patients with significant comorbidities [1].

Abstract:
Abstract A model has been developed to design a new active, steerable end-effector for minimally invasive surgery. Active material is incorporated into the surgical instrument to increase the degrees of freedom available to the surgeon. This paper focuses on the modeling of the end-effector using both piezoelectric ceramic and electroactive polymer (EAP) materials. The end-effector design consists of a number of bimorph actuator sections in series with each active layer being individually controlled. Each section may behave as either a bimorph or a unimorph actuator, where in the case of unimo

Abstract:
Abnormal loading of the medial compartment of the knee is believed to be a contributing factor to the development of medial compartment knee osteoarthritis (OA) [1]. Treatment strategies for patients with medial knee OA include both invasive (i.e., surgery) and non-invasive (e.g., gait modification) options. A variety of modified gait patterns have been proposed as non-invasive treatments for patients with medial knee OA.

Abstract:
A number of situations of engineering interest are associated with the relatively rapid filling of a nearly horizontal pipeline. The displacement of the air may lead to a number of different transient conditions of concern in engineering design. Our specific application relates to the use of underground storage tunnels to mitigate combined sewage overflows. Historically, the operation of these system have created surges initiated when the tunnel passes to a surcharged condition that have resulted in “geysering” in which an air/water combination is expelled to the ground surface through manhole

Abstract:
A study of the response of a turbojet engine to the steady-state and the turbulence-type dynamic inlet distortion is presented in this paper. The steady-state distortion is generated by a 180° extent, 36 mesh screen, and the turbulence-type dynamic distortion by a 180° extent plate with 50% blockage ratio at the engine face. This plate can produce a very strong pressure fluctuation at the engine face. The statistical analysis shows that the APD of pressure fluctuation follows approximately the Normal Distribution except those cases near rotating stall or surge. Results from testing show: 1) in

Abstract:
We present an experimental system for robot assisted, minimally invasive surgery that is capable of force measurement and haptic feedback. While minimally invasive surgery with robots provides several advantages like reduced tissue trauma and shorter recovery times, there are also some inherent short-comings. Referring to surgeons, the most significant issue is the lack of haptic feedback. This often causes collateral trauma and leads to prolonged operation time. Therefore we have developed an open platform, which combines the advantages of present systems with the possibility of force reflect

In this study, we have developed a robust and accurate algorithm based on concept of two-third power law in human motor control to segment the hand trajectory of robotic surgeons into smaller segments. We hypothesis that tracking a longer trajectory is subjected to higher cognitive workload that may lead in to an imperfect CNS performance in programming muscle activation which will lead to more number of segment trajectories and pause points in hand movements. To test our hypothesis, after segmenting the trajectory, we determine the correlation between affine velocity and workload extracted fr

Abstract:
Abstract Minimally Invasive Surgery (MIS) has gained popularity in current abdominal surgical procedures due to its reduced skin incision length, shortened recovery time and decreased postoperative complications. One trend is to enhance these benefits by developing technologies to expand the application of single incision laparoscopic surgery (SILS) which has even less incision and incision-related complication. However, the practical application of SILS has been constrained by many complexities, including fundamental procedure issues (e. g. limited space), as well as the issues related to sur
