The optimal survivor search problem is to maximize the probability of finding a moving target alive. The target may be a person missing at sea or lost in a wilderness area. In a multistate target problem, the target is moving and changing states stochastically. Each state may imply different motion and detectability assumptions. We find necessary and sufficient conditions for optimal detection ...

Outcome prediction of neurological recovery in an unconscious survivor of cardiorespiratory arrest is difficult and uncertain. We describe the case of a 25-yr-old post-arrest survivor who made a remarkable neurological improvement despite a seemingly hopeless prognosis. Conventional clinical and neurophysiological assessments need to be interpreted with care in the presence of uncontrolled seiz...

Stroke is a leading cause of severe, long-term disability. Most stroke survivors are cared for in the home by a family caregiver. Caregiver stress is a leading cause of stroke survivor institutionalization, which results in significant costs to the healthcare system. Stroke family caregiver and dyad intervention studies have reported a variety of outcomes. A critical analysis of 17 caregiver in...

In a Viterbi decoder, there are two known memory organization techniques for the storage of survivor sequences from which the decoded information sequence is retrieved, namely register exchange method and traceback method. This paper extends previously known traceback approaches describes two new traceback algorithms, and compares various traceback methods with each other. Memory size, latency ...

This paper is concerned with identification of a competing risks model with unknown transformations of latent failure times. The model in this paper includes, as special cases, competing risks versions of proportional hazards, mixed proportional hazards, and accelerated failure time models. It is shown that covariate effects on latent failure times, cause-specific link functions, and the joint ...

This article offers a critical assessment of the “survivor bonds” (SBs) proposal recently put forward by Blake and Burrows, which calls for the government to issue bonds whose coupon payments are contingent on the proportions of retirees surviving to particular ages. It suggests that the proposal has considerable merit and discusses the circumstances in which SBs would be useful riskmanagement ...

Per-survivor iterative timing recovery was proposed by Kovintavewat, Barry, Erden, and Kurtas [1] to perform timing recovery, equalization, and errorcorrection decoding jointly. In this paper, we investigate the robustness of this scheme in the situation where the channel is dominated by media jitter noise. We apply the pattern-dependent noisepredictive (PDNP) technique to per-survivor iterativ...

| A time-recursive algorithm for the joint estimation of angles of arrival (AOA), multipath channel coe cients, and digital data is developed. This algorithm, which is applicable to TDMA cellular and PCS systems, is based on the technique of Per-Survivor Processing (PSP). The PSP-based adaptive array processing algorithm uses per-survivor estimation of AOAs and channel coe cients embedded into ...

In stage V twin-twin transfusion syndrome (TTTS), up to 50% of surviving twins die or experience permanent disabilities, likely due to acute intertwin hemorrhage resulting in sudden severe anemia of the survivor. Although fetal middle cerebral artery (MCA) Doppler studies demonstrate strong correlation with fetal hemoglobin values, acute hemorrhagic events are more difficult to diagnose, and op...
