Exploring Shaking for Cancer Treatment

1.Double-sided role of vibration and shaking Removing vibration and shaking is a pivotal engineering task,which is showcased,for instance,in spacecraft attitude control systems that ensure a precise three-dimensional orientation.Vibration or shaking,such as precession caused by external torque,nutation stemming from off-axis angular momentum,and wobbling due to geometric misalignment,necessitate active and passive damping mechanisms.This principle extends beyond spacecraft to centrifugation techniques,pivotal not only in washing machines but also in a spectrum of biomedical apparatuses used for isolating cells and organelles and separating DNA and proteins.

Review and update on the management of triangular fibrocartilage complex injuries in professional athletes

Triangular fibrocartilage complex injuries are common in amateur and professional sports.These injuries are mainly caused by acute or chronic repetitive axial loads on the wrist,particularly on the ulnar side and in association with rotations or radial/ulnar deviations.In order to treat professional athletes,a detailed specific knowledge of the pathology is needed.Moreover,the clinician should fully understand the specific and unique environment and needs of the athletes,their priorities and goals,the type of sport,the time of the season,and the position played.An early diagnosis and appropriate management with the quickest possible recovery time are the uppermost goals for both the athlete and the surgeon.A compromise between conservative vs surgical indications,athletes’needs and expectations,and financial implications should be achieved.Arthroscopic procedures should be timely planned when indicated as they could allow early diagnosis and treatment at the same time.Conservative measures are often used as first line treatment when possible.Peripheral lesions are treated by arthroscopic repair,whilst central lesions are treated by arthroscopic debridement.Further procedures(such as the Wafer procedure,ulnar osteotomies,etc.)have specific indications and great implications with regard to rehabilitation.

Traffic light detection and recognition in intersections based on intelligent vehicle

To ensure revulsive driving of intelligent vehicles at intersections, a method is presented to detect and recognize the traffic lights. First, the stabling siding at intersections is detected by applying Hough transformation. Then, the colors of traffic lights are detected with color space transformation. Finally, self-associative memory is used to recognize the countdown characters of the traffic lights. Test results at 20 real intersections show that the ratio of correct stabling siding recognition reaches up to 90%;and the ratios of recognition of traffic lights and divided characters are 85% and 97%, respectively. The research proves that the method is efficient for the detection of stabling siding and is robust enough to recognize the characters from images with noise and broken edges.

Laparoscopic complete mesocolic excision with central vascular ligation in right colon cancer:A comprehensive review

Aim of the study is to comprehensively review the latest trends in laparoscopic complete mesocolic excision(CME) with central vascular ligation(CVL) for the multimodal management of right colon cancer. Historical and up-to-date anatomo-embryological concepts are analyzed in detail,focusing on the latest studies of the mesenteric organ,its dissection by mesofascial and retrofascial cleavage planes,and questioning the need for a new terminology in colonic resections. The rationale behind Laparoscopic CME with CVL is thoroughly investigated and explained. Attention is paid to the current surgical techniques and the quality of the surgical specimen,yielded through mesocolic,intramesocolic and muscularis propria plane of surgery. We evaluate the impact on long term oncologic outcome in terms of local recurrence,overall and disease-free survival,according to the plane of resection achieved. Conclusions are drawn on the basis of the available evidence,which suggests a pivotal role of laparoscopic CME with CVL in the multimodal management of right sided colonic cancer: performed in the right mesocolic plane of resection,laparoscopic CME with CVL demonstrates better oncologic results when compared to standard non-mesocolic planes of surgery,with all the advantages of laparoscopic techniques,both in faster recovery and better immunological response. The importance of minimally invasive mesoresectional surgery is thus stressed and highlighted as the new frontier for a modern laparoscopic total right mesocolectomy.

Control mechanism and technique of floor heave with reinforcing solid coal side and floor corner in gob-side coal entry retaining

Floor heave is the most common convergence in gob-side entry retaining.The paper analyzes the form,process and characteristics of gob-side entry retaining with the comprehensive methods of theoretical analysis,numerical simulation and the field trial.Research results present that bending and folding floor heave is the main factor in the stage of the first panel mining;squeezing and fluidity floor heave plays a great role in the stable stage of gob-side entry retaining;the combination of the former two factors affects mainly the stage of the second mining ahead;abutment pressure is a fundamental contribution to the serious floor heave of gob-side entry retaining,and sides corners of solid coal body are key part in the case of floor heave controlling of gob-side entry retaining.Floor heave of gob-side entry retaining can be significantly controlled by reinforcing sides and corners of solid coal body,and influence rules on the floor heave of gob side entry retaining of sides supporting strength and the bottom bolt orientation in solid coal side are obtained.Research results have been successfully applied in gob-side entry retaining of G20-F23070 face haulage roadway in #2 coal mine of Pingmei Group,and the field observation shows that the proposed technique is an effective way in controlling the floor heave of gob-side entry retaining.

Laparoscopic cholecystectomy for a left-sided gallbladder

Cholecystectomy is a common procedure.Abnormalities in the anatomy of the biliary system are common but an abnormal location of the gallbladder is much rarer.Despite frequent pre-operative imaging,the aberrant location of the gallbladder is commonly discovered at surgery.This article presents a case of a patient with the gallbladder located to the left of the falciform ligament in the absence of situs inversus totalis that presented with right upper quadrant pain.A laparoscopic cholecystectomy was performed and it was noted that the cystic duct originated from the right side.The presence of a left sided gall bladder is often associated with various biliary,portal venous and other anomalies that might lead to intra-operative injuries.The spectrum of unusual positions and anatomical gallbladder abnormalities is reviewed in order to facilitate elective and emergent cholecystectomy as well as other hepatobiliary procedures.With proper identification of the anatomy,minimally invasive approaches are still considered safe.

A Looped Functional Method to Design State Feedback Controllers for Lurie Networked Control Systems

Dear Editor,This letter deals with the stabilization of Lurie networked control systems with network-induced delays(NID).By constructing a twosided looped Lyapunov functional,a sufficient condition is derived to ensure the absolute stability of the resultant closed-loop system under a state feedback controller.Then,based on this condition,a cone complementary linearisation(CCL)iterative algorithm is presented to design state feedback controller.It is shown via a numerical example that the proposed method can deliver less conservative results as well as fewer iterations if compared with existing ones.

ON THE SOLUTION OF THE SINGULAR INTEGRAL EQUATIONS WITH BOTH CAUCHY AND CONVOLUTION KERNEL

The following equations are basic forms of C-K equation (which is simplified in the following as singu-lar integral equations with convolution, that is C-K equations):where a,b,a_j,b_j are known constants or known functions, and find its solution f L_P(R), {0} or {α,β}.There were rather complete investigations on the method of solution for equations of Cauchy type aswell as integral equations of convolution type. But there is not investigation to the C-K equations, nodoubt, such that is important.
