Population status of the Oblong turtle in Armadale’s wetlands

The Oblong turtle (Chelodina oblonga) is becoming a flagship species for Perth wetlands. As an apex predator the species plays an essential role in wetland ecosystem health. However, urban populations appear to be in decline due to numerous threats including habitat modification and destruction, wildlife-vehicle mortality, and predation. Three wetlands within City of Armadale were identified by the Armadale Gosnells Landcare Group as potentially significant sites for populations of the Oblong turtle. No baseline information on the presence and/or population status of C. oblonga within these wetlands currently exists. Modified funnel traps and fyke nets were deployed for an overnight trapping period in each wetland during October 2020. In total, thirty-four turtles were captured and released from the wetlands. The turtles captured were mainly adults and the few juveniles captured were >100 mm. Sex ratio varied from heavily male-dominated to slightly female-dominated. The results suggest that these populations have been experiencing low recruitment, and sex biased mortality at the heavily male dominated population. Continued monitoring of these populations as well as expansion of surveys to additional wetlands will enable a deeper understanding of C. oblonga population dynamics within the City of Armadale, as well as wetland-specific management recommendations

ErbB- and MUC1-targetted CAR-T cell immunotherapy of oral squamous cell carcinoma

Chimeric antigen receptor T (CAR-T) cell therapy has shown great success in treating B cell malignancies however, there are many challenges which limit their therapeutic efficacy in solid tumours. Immunotherapy of head and neck squamous cell carcinoma (HNSCC), and in particular, oral squamous cell carcinoma (OSCC), presents a unique set of challenges including lack of consistently expressed tumour associated antigens (TAAs) and the immunosuppressive tumour microenvironment (TME). Currently, there are few clinical trials investigating the use of CAR-T cells in HNSCC/OSCC however results from trials investigating similar solid tumours, such as breast cancer, can be adopted to help evaluate the use of CAR-T in this cancer. In this review, the process of CAR-T cell engineering, and different generations of these cells will be summarised, highlighting their potential use in treating HNSCC through targeting ErbB and MUC1; TAAs highly expressed by this solid tumour. Potential strategies including combination therapy, utilising both TAA-targeting CAR-Ts and immune checkpoint inhibitors, such as PD-L1, has been discussed, in an attempt to develop synergistic anti-tumour responses. In addition to this, the use of dual-targeting CAR-T cells, synthetic NOTCH (synNOTCH) receptors and alternative non-tumour targets of the TME have been reviewed. Such combination therapies have been shown to help limit solid tumour progression and enhance both the safety and efficacy of CAR-T cell immunotherapy, which may be adopted for the treatment and management of OSCC

Fees for Information Services to Hospitals: A California Experience

The project was directed toward planning, developing, and implementing a subregional biomedical information network among the forty-three health care facilities (hospitals) of the four-county area served by Loma Linda University\u27s health sciences library. The project coordinator contacted administrators and health care professionals in the forty-three institutions to present a plan for the network. The health care facilities were encouraged to support the continuation of the network through contract fees. The availability of specific information services was assured through contractual agreements. It was anticipated that the subregional network would be self-supporting after the twelve-month project period (December 1, 1976-November 30, 1977). The working territory (40,429 square miles) encompassed Mono, Inyo, Riverside, and San Bernardino counties. The project resulted in nine of the forty-three hospitals signing annual contracts for library services. It is recommended that projects of this kind extend beyond a year\u27s duration in order to educate health professionals concerning the value of access to biomedical literature in improving patient care

Redundant Arrays of IDE Drives

The next generation of high-energy physics experiments is expected to gather prodigious amounts of data. New methods must be developed to handle this data and make analysis at universities possible. We examine some techniques that use recent developments in commodity hardware. We test redundant arrays of integrated drive electronics (IDE) disk drives for use in offline high-energy physics data analysis. IDE redundant array of inexpensive disks (RAID) prices now equal the cost per terabyte of million-dollar tape robots! The arrays can be scaled to sizes affordable to institutions without robots and used when fast random access at low cost is important. We also explore three methods of moving data between sites; internet transfers, hot pluggable IDE disks in FireWire cases, and writable digital video disks (DVD-R).Comment: Submitted to IEEE Transactions On Nuclear Science, for the 2001 IEEE Nuclear Science Symposium and Medical Imaging Conference, 8 pages, 1 figure, uses IEEEtran.cls.

Multi-Terabyte EIDE Disk Arrays running Linux RAID5

High-energy physics experiments are currently recording large amounts of data and in a few years will be recording prodigious quantities of data. New methods must be developed to handle this data and make analysis at universities possible. Grid Computing is one method; however, the data must be cached at the various Grid nodes. We examine some storage techniques that exploit recent developments in commodity hardware. Disk arrays using RAID level 5 (RAID-5) include both parity and striping. The striping improves access speed. The parity protects data in the event of a single disk failure, but not in the case of multiple disk failures. We report on tests of dual-processor Linux Software RAID-5 arrays and Hardware RAID-5 arrays using a 12-disk 3ware controller, in conjunction with 250 and 300 GB disks, for use in offline high-energy physics data analysis. The price of IDE disks is now less than $1/GB. These RAID-5 disk arrays can be scaled to sizes affordable to small institutions and used when fast random access at low cost is important.Comment: Talk from the 2004 Computing in High Energy and Nuclear Physics (CHEP04), Interlaken, Switzerland, 27th September - 1st October 2004, 4 pages, LaTeX, uses CHEP2004.cls.

Passive States for Essential Observers

The aim of this note is to present a unified approach to the results given in \cite{bb99} and \cite{bs04} which also covers examples of models not presented in these two papers (e.g. $d$-dimensional Minkowski space-time for $d\geq 3$). Assuming that a state is passive for an observer travelling along certain (essential) worldlines, we show that this state is invariant under the isometry group, is a KMS-state for the observer at a temperature uniquely determined by the structure constants of the Lie algebra involved and fulfills (a variant of) the Reeh-Schlieder property. Also the modular objects associated to such a state and the observable algebra of an observer are computed and a version of weak locality is examined.Comment: 27 page
