The problem of Unequal Area Facility Layout Planning (UA-FLP) has been addressed by a large number of approaches considering a set of quantitative criteria. Moreover, more recently, the personal qualitative preferences of an expert designer or decision-maker (DM) have been taken into account too. This article deals with capturing more than a single DM’s personal preferences to obtain a common and collaborative design including the whole set of preferences from all the DMs to obtain more complex, complete, and realistic solutions. To the best of our knowledge, this is the first time that the preferences of more than one expert designer have been considered in the UA-FLP. The new strategy has been implemented on a Coral Reef Optimization (CRO) algorithm using two techniques to acquire the DMs’ evaluations. The first one demands the simultaneous presence of all the DMs, while the second one does not. Both techniques have been tested over three well-known problem instances taken from the literature and the results show that it is possible to obtain sufficient designs capturing all the DMs’ personal preferences and maintaining low values of the quantitative fitness function.

Criminal Justice Response

Since 2000, the Scottish Government has adopted a gendered definition of domestic abuse which explicitly positions it as both a cause and a consequence of gender inequality. Following the launch of a new strategy to prevent and eradicate violence against women and girls, the Scottish Government announced proposals to create, for the first time, a bespoke offence of domestic abuse, designed to encompass the spectrum of abusive acts that constitute domestic abuse, including emotional and psychological abuse. The new offence is intended to better reflect the experience of victims subject to coercive control, improve the criminal justice response and facilitate access to justice. It represents one of the most radical attempts yet to align the criminal justice response with contemporary policy and feminist conceptual understanding of domestic abuse as a form of coercive control. Drawing on feminist scholarship which has interrogated the value of law reform, we critically assess the scope of the legislation, the likely challenges associated with its use in the Scottish context, and the potential for unintended consequences.

17082 Background: Chemotherapy is main treatment for advanced NSCLC. But its efficacy is quite small with improvement of 1–2 months in median survival. New strategy against NSCLC is needed. Oncolytic adenovirus H101 is found to be effective against NSCLC. This trial is desigened to investigate efficacy and toxicity of intratumoral injection of H101 in combination with chemotherapy in the treatment of NSCLC. Methods: The NSCLC patients confirmed cytologically or pathologically were randomized to intratumoral injection of adenovirus H101 (1.5 × 1012 viral particles) plus NP chemotherapy (arm A) or NP chemotherapy (arm B). Objetive response was evaluated every two cycles and time to progression (TTP) and overall survival were followed up. Results: Out of 18 evaluable patients in Arm A, 4 patients showed partial response (PR),3 minor response(MR), 7 stable disease (SD) and 4 disease progression (PD), while in Arm B 16 evaluable patients showed 3 PR, 4 MR, 3 SD and 6 PD. At the first time of response evaluation, there was 1 PD in Arm A,but in Arm B there were 5 of PD. Failure rate in Arm B was significantly higher than in Arm B. Survival curves between the two arms were similar. Six month, 9 month and 1 year survival rates were slightly higher in Arm B and median TTP was also prolonged in Arm A. Except non-infectious fever, Arm A was similar in other toxicities to Arm B. there was only 2 patients developing mild pneumothorax. Conclusions: Intratumoral injection of H101 1.5 × 1012 viral particles in combination with NP chemotherapy was feasible, effective and safe in treatment of advanced NSCLC. No significant financial relationships to disclose.

AbstractBackgroundHigh-fidelity preservation strategies for primary tissues are in great demand in the single cell RNAseq community. A reliable method will greatly expand the scope of feasible collaborations and maximize the utilization of technical expertise. When choosing a method, standardizability is as important a factor to consider as fidelity due to the susceptibility of single-cell RNAseq analysis to technical noises. Existing approaches such as cryopreservation and chemical fixation are less than ideal for failing to satisfy either or both of these standards.ResultsHere we propose a new strategy that leverages preservation schemes developed for organ transplantation. We evaluated the strategy by storing intact mouse kidneys in organ transplant preservative solution at hypothermic temperature for up to 4 days (6 hrs, 1, 2, 3, and 4 days), and comparing the quality of preserved and fresh samples using FACS and single cell RNAseq. We demonstrate that the strategy effectively maintained cell viability, transcriptome integrity, cell population heterogeneity, and transcriptome landscape stability for samples after up to 3 days of preservation. The strategy also facilitated the definition of the diverse spectrum of kidney resident immune cells, to our knowledge the first time at single cell resolution.ConclusionsHypothermic storage of intact primary tissues in organ transplant preservative maintains the quality and stability of the transcriptome of cells for single cell RNAseq analysis. The strategy is readily generalizable to primary specimens from other tissue types for single cell RNAseq analysis.
