Abstract This paper develops new solution procedures for the order picker routing problem in U-shaped picking zones with a movable depot, which has so far only been solved using simple heuristics. The presents first exact approach, based on combinatorial Benders decomposition, as well heuristic approach dynamic programming that extends idea of venerable sweep algorithm. In computational study, ...

OBJECTIVE Non-adherence is a major problem in the treatment of schizophrenia. Depot antipsychotic drugs are thought to reduce relapse rates by improving adherence, but a systematic review of long-term studies in outpatients is not available. METHOD We searched the Cochrane Schizophrenia Group's register, ClinicalTrials.gov, Cochrane reviews on depot medication, and the reference sections of i...

among numerous np-hard problems, the traveling salesman problem (tsp) has been one of the most explored, yet unknown one. even a minor modification changes the problem’s status, calling for a different solution. the generalized traveling salesman problem (gtsp)expands the tsp to a much more complicated form, replacing single nodes with a group or cluster of nodes, where the objective is to fi...

The possibility that an infant’s diet may influence the later development of obesity or of atheroma gives this subject its interest and importance. The concept of the body’s depot fat as constituting an ‘organ’ is probably a useful one, but only so long as it does not lead to unwarranted simplification. For instance, samples of depot fat taken from the adipose tissue of a baby’s buttock tend to...

Aiming at the problems that tomatoes are fragile and traditional end-effector design is not suitable for tomato picking, a combination of bionic principle FRE structure finger was proposed. Based on physical properties tomatoes, flexible underactuated picking sorting designed. The optimal structural parameters fingers were determined by finite element analysis, grasping experiment carried out. ...

A high-fat diet has been recognized as an important risk factor of obesity, with variable impacts of different fatty acid compositions on the physiological process. To understand the effects of a high-margarine/lard diet, which is a major source of trans fatty acids (TFAs)/ saturated fatty acids (SFAs), elaidic acid as a biomarker of margarine intake was used to screen affected adipokines on ma...

OBJECTIVE To report a case of right posterior subcapsular cataract induced by 3-monthly depot luteinizing hormone-releasing hormone (LHRH) analogue therapy in a patient with early prostate cancer. CASE PRESENTATION A 52-year-old male with static myopia of several years' duration was given a 3-month depot LHRH analogue (goserelin 10.8 mg) as part of neoadjuvant treatment for early prostate can...

It has long been recognized that body fat distribution and regional adiposity play a major role in the control of metabolic homeostasis. However, the ability to study and compare the cell autonomous regulation and response of adipocytes from different fat depots has been hampered by the difficulty of inducing preadipocytes isolated from the visceral depot to differentiate into mature adipocytes...
