5.2. Enumeration with Magic Centre Subsquare 2 The squares are divided into non-equivalent types in the same manner as for centre subsquare 1 in . Table 4 shows the possible pairs of complement sets used in the construction of a minimum PSCMS with magic centre subsquare 2, as shown in Figure 4b. Lemma 8.

1 INTRODUCTION Pancreatic ductal adenocarcinoma (PDAC) has one of the poorest prognostic outcomes of all major cancers.1 Surgical resection is the only potential curative intent treatment option for PDAC patients, but only 10%–20% of patients are eligible for surgery at the time of diagnosis.2 There has been an increase in the administration of neoadjuvant chemotherapy (NAC) in upfront and borderline resectable PDAC patients due to a number of reasons3: (1) to downstage the disease; (2) to...

Introduction The behaviour of a system dynamics model is determined by its structure expressed in its stocks, flows, and feedback loops. The latter are especially important as they represent endogeneity in the system and provide intuitive explanations of behaviour. Further, knowing which loops are influential can help determine suitable interventions for system change. Several methods have been developed to quantify the relationship between feedback loops and behaviour.
