ABSTRACT Introduction This brief report describes the process, used by the 1st Infantry Division (1ID) and Irwin Army Community Hospital (IACH) at Fort Riley, Kansas, for conducting pooled testing collection of over 2,500 Soldiers prior to a large-scale exercise involving multiple units. Materials and Methods The authors captured after action review comments on the process and results of their pooled specimen collection site. Pooled specimen test results were reviewed and classified according to Aberdeen Proving Ground criteria to determine the percentage of successful and failed pooled specimens. Results 1ID and IACH performed pooled testing collection and shipment of 2,684 specimens divided into 298 pools over 6 flight manifests. Of the 298 pooled specimens, 4 (1.34%) were found to be inconclusive or invalid, and the other 294 (98.7%) had sufficient number of human cells to be certified as SARS-CoV-2 (COVID-19) positive or COVID-19 not detected. Conclusion Pooled testing collection is a complex process that may continue to be a requirement for mass screening of COVID-19 prior to military operations. While planning should be tailored to the specific mission and unit, key factors that the authors feel are required for pooled testing to be successful in any situation are standardized training and personnel continuity, quality assurance, administrative oversight by the unit, and collaboration and communication between all involved entities.

The success of the Program of housing stock renovation in Moscow depends on the efficiency of resource management. One of the main urban planning documents that determine the nature of the reorganization of residential areas included in the Program of renovation is the territory planning project. The implementation of the planning project is a complex process that has a time point of its beginning and end, and also includes a set of interdependent parallel-sequential activities. From an organizational point of view, it is convenient to use network planning and management methods for project implementation. These methods are based on the construction of network models, including its varieties – a Gantt chart. A special application has been developed to simulate the implementation of planning projects. The article describes the basic principles and elements of modeling. The list of the main implementation parameters of the Program of renovation obtained with the help of the developed software for modeling is presented. The variants of using the results obtained for a comprehensive analysis of the implementation of large-scale urban projects are proposed.

Position information is very important tactical information in large-scale joint military operations. Positioning with datalink time of arrival (TOA) measurements is a primary choice when a global navigation satellite system (GNSS) is not available, datalink members are randomly distributed, only estimates with measurements between navigation sources and positioning users may lead to a unsatisfactory accuracy, and positioning geometry of altitude is poor. A time division multiple address (TDMA) datalink cooperative navigation algorithm based on INS/JTIDS/BA is presented in this paper. The proposed algorithm is used to revise the errors of the inertial navigation system (INS), clock bias is calibrated via round-trip timing (RTT), and altitude is located with height filter. The TDMA datalink cooperative navigation algorithm estimate errors are stated with general navigation measurements, cooperative navigation measurements, and predicted states. Weighted horizontal geometric dilution of precision (WHDOP) of the proposed algorithm and the effect of the cooperative measurements on positioning accuracy is analyzed in theory. We simulate a joint tactical information distribution system (JTIDS) network with multiple members to evaluate the performance of the proposed algorithm. The simulation results show that compared to an extended Kalman filter (EKF) that processes TOA measurements sequentially and a TDMA datalink navigation algorithm without cooperative measurements, the TDMA datalink cooperative navigation algorithm performs better.

The Impact

Abstract Background The use of a remote specimen collection strategy employing a kit designed for unobserved self-collection for SARS-CoV-2 RT-PCR can decrease the use of PPE and exposure risk. To assess the impact of unobserved specimen self-collection on test performance, we examined results from a SARS-CoV-2 qualitative RT-PCR test for self-collected specimens from participants in a return-to-work screening program and assessed the impact of a pooled testing strategy in this cohort. Methods Self-collected anterior nasal swabs from employee return to work programs were tested using the Quest Diagnostics SARS-CoV-2 RT-PCR EUA. The Ct values for the N1 and N3 N-gene targets and a human RNase P (RP) gene control target were tabulated. For comparison, we utilized Ct values from a cohort of HCP-collected specimens from patients with and without COVID-19 symptoms. Results Among 47,923 participants, 1.8% were positive. RP failed to amplify for 13/115,435 (0.011%) specimens. The median (IQR) Cts were 32.7 (25.0-35.7) for N1 and 31.3 (23.8-34.2) for N3. Median Ct values in the self-collected cohort were significantly higher than those of symptomatic, but not asymptomatic patients. Based on Ct values, pooled testing with 4 specimens would have yielded inconclusive results in 67/1,268 (5.2%) specimens but only a single false-negative result. Conclusions Unobserved self-collection of nasal swabs provides adequate sampling for SARS-CoV-2 RT-PCR testing. These findings alleviate concerns of increased false negatives in this context. Specimen pooling could be used for this population as the likelihood of false negative results is very low due when using a sensitive, dual-target methodology.

And Control

The non-motorized air systems for intelligence, monitoring and control of the earth surface have gained currency and are used for various tactic flight’s tasks and missions. The non-motorized aircrafts (NMA) and the air-monitoring systems that include board and land part are key elements of these systems. The world experience in using NMA for these uses shows that they are most suitable where the exploitation conditions are very extreme and there is an unacceptable risk for operations of piloted aviation. Such are intelligence and observation of strictly guarded sites, zones, where military operations are conducted as well as regions with large scale fires and floods. The use of people in these conditions is connected with actual threat for their lives and practically, NMA as a tool for collecting and processing of information is irreplaceable. Keywords: registration of images, methods, information systems, non-motorized aircrafts.

Abstract3 Commando Brigade’s delivery of pre-hospital (Role 1) care has until now largely been based around junior doctors delivering trauma-based resuscitation and limited primary care from small self-contained Regimental Aid Posts (RAPs). With the drawdown of large scale operations in Iraq and Afghanistan, and the diversity of potential future military operations, the deficiency of General Practitioner(GP)-led care in the deployed setting has become more evident, and this has driven the requirement for a deployable primary care facility in the form of a Medical Reception Station (MRS). This paper describes the evolution of this project, the realities of deploying a new medical capability for the first time, some of the issues faced, and the potential utility of such a medical facility in future.

In Chapter 6 the various strands of the study come together as the actual performance of the Gulf armies is appraised. Given the limited involvement of GCC countries in military operations, the available evidence to base judgments upon their battlefield effectiveness is slender. Therefore, the analysis integrates lessons that may be learned from training and large-scale exercises GCC armies have participated in. To understand Gulf armies’ deficiencies, special attention is paid to the instruction and cultural aspects of the most prestigious military specialization, pilot training. In the second section the scant foreign deployment of Gulf militaries is examined, with special emphasis on the UAE, the only GCC army with extensive experience in this area. The bulk of this chapter centers on the ongoing civil war in Yemen in which the Saudi and Emirati armed forces have played a major role, thus allowing us the opportunity to assess their performance.

2006-2010: during these four decisive years in the history of the peace movement, the movement experienced a dramatic eclipse. Within an Israeli society that had grown increasingly nationalist, more attached to symbols of Jewish identity and the memory of the Holocaust, more concerned than ever about security, and less interested in making peace with the Palestinians, the movement was incapable both of promoting a message of peace and taking a stance on the subject of human rights. It seemed apathetic, paralyzed, almost non-existent in the face of the terrible events that marked the period. This chapter shows how and why this eclipse occurred. These years were punctuated by two large-scale military operations, the war in Lebanon in July 2006 and Operation Cast Lead in the Gaza Strip from late 2008 to early 2009. These hostilities caused turmoil in the Israeli collective psychology and the perception of war and peace.

Since 1900, United States troops have fought in more foreign conflicts than any other nation on Earth. Most Americans supported those actions, believing that they would keep the scourge of war far from our homes. But the strategy seems to have failed—it certainly did not prevent terror attacks against the U.S. mainland. The savage Oklahoma City bombing in 1995 and the 11 September 2001 (9/11) attacks on New York and Washington, D.C. were not the first to inflict war damage in America’s 48 contiguous states, however—nor were they the first warlike actions to harm innocent citizens since the Civil War. Paradoxically, making war abroad has always required practicing warfare in our own back yards. Today’s large, mechanized military training exercises have degraded U.S. soils, water supplies, and wildlife habitats in the same ways that the real wars affected war-torn lands far away. The saddest fact of all is that the deadly components of some weapons in the U.S. arsenal never found use in foreign wars but have attacked U.S. citizens in their own homes and communities. The relatively egalitarian universal service of World War II left a whole generation of Americans with nostalgia and reverence for military service. Many of us, perhaps the majority, might argue that human and environmental sacrifices are the price we must be willing to pay to protect our interests and future security. A current political philosophy proposes that the United States must even start foreign wars to protect Americans and their homes. But Americans are not fully aware of all the past sacrifices—and what we don’t know can hurt us. Even decades-old impacts from military training still degrade land and contaminate air and water, particularly in the arid western states, and will continue to do so far into the future. Exploded and unexploded bombs, mines, and shells (“ordnance,” in military terms) and haphazard disposal sites still litter former training lands in western states. And large portions of the western United States remain playgrounds for war games, subject to large-scale, highly mechanized military operations for maintaining combat readiness and projecting American power abroad.

We have been long involved in large-scale computational fluid dynamics (CFD) simulations in aerospace research. These days, as the computer power grows, output data from the simulations becomes larger and larger, and we feel that the current visualization methodology has its limitation in understanding. Thus, with the target concepts of reality, collaboration, and communication, we has built an immersive and interactive visualization system with a large-sized wall-type display. The system, which has been in operation since April 2001, is driven by a SGI Onyx 3400 server with 32 CPUs, 64Gbytes memory, and 6 IR3 graphics pipelines, and comprises a 4.6×1.5-meter (15×5-foot) rear projection screen with 3 high-resolution CRT projectors, supporting stereoscopic viewing, easy color/luminosity matching, and accurate edge-blending. The system is mainly used for visualization of large-scale CFD simulations. This paper will describe the new visualization system introduced at the National Aerospace Laboratory of Japan, and the features of the system are discussed while illustrating some typical visualized examples.

This paper starts with short descriptions of emulsion preparation methods used at large and smaller scales. We give scaling relations as they are generally used, and focus on the central role that interfacial tension plays in these relations. The actual values of the interfacial tension are far from certain given the dynamic behavior of surface-active components, and the lack of measurement methods that can be applied to conditions as they occur during large-scale preparation. Microfluidic techniques are expected to be very instrumental in closing this gap. Reduction of interfacial tension resulting from emulsifier adsorption at the oil-water interface is a complex process that consists of various steps. We discuss them here, and present methods used to probe them. Specifically, methods based on microfluidic tools are of great interest to study short droplet formation times, and also coalescence behavior of droplets. We present the newest insights in this field, which are expected to bring interfacial tension observations to a level that is of direct relevance for the large-scale preparation of emulsions, and that of other multi-phase products.
