We consider the carrier transport and plasmonic phenomena in the lateral carbon nanotube (CNT) networks forming the device channel with asymmetric electrodes. One electrode is the Ohmic contact to the CNT network and the other contact is the Schottky contact. These structures can serve as detectors of the terahertz (THz) radiation. We develop the device model for collective response of the lateral CNT networks which comprise a mixture of randomly oriented semiconductor CNTs (s-CNTs) and quasi-metal CNTs (m-CNTs). The proposed model includes the concept of the collective twodimensional (2D) plasmons in relatively dense networks of randomly oriented CNTs (CNT "felt") and predicts the detector responsivity spectral characteristics exhibiting sharp resonant peaks at the signal frequencies corresponding to the 2D plasmonic resonances. The detection mechanism is the rectification of the ac current due the nonlinearity of the Schottky contact current-voltage characteristics under the conditions of a strong enhancement of the potential drop at this contact associated with the plasmon excitation. The detector responsivity depends on the fractions of the s- and m-CNTs. The burning of the near-contact regions of the m-CNTs or destruction of these CNTs leads to a marked increase in the responsivity in agreement with our experimental data. The resonant THz detectors with sufficiently dense lateral CNT networks can compete and surpass other THz detectors using plasmonic effects at room temperatures. [ABSTRACT FROM AUTHOR]

Background: On October 7, 2023, Hamas carried out an unprecedented attack on the State of Israel and kidnapped 251 people into captivity to the Gaza Strip. Several months later, as part of a humanitarian exchange deal, 105 hostages were released in five phases and admitted to one of six hospitals throughout the country for treatment. Shamir Medical Center (SMC) was one of these facilities. This study aims to describe the structure, process and outcomes of establishing a comprehensive, multi-step, operational protocol for receiving hostages returning from captivity., Method: The process of preparing SMC as a receiving center, the establishment of procedures for implementation of the medical protocol, and the assessment of multi-disciplinary team preparedness and implementation and outcomes in an institutional protocol are described., Results: 24 returning hostages were received at SMC. Social workers, dietitians and translators were used by 100% of the majority group of returning hostages from the same country of origin and the sole individual from the other country of origin utilized a dietitian, social worker, ENT consultations, and a hearing test. Among the majority group, orthopedic and dermatological consultations were utilized by 17.4% and 13% received an ENT consultation. Of the administered imaging, 13% received a chest X-ray, 8.7% received a limb X-ray, 17.4% received a head CT scan, and 4.3% received an abdominal CT. In addition, 21.7% were provided antibiotic therapy. Protocol efficacy was measured by assessing time to various operational aspects of protocol implementation and medical procedures such as mean hours to room assignment, primary physician evaluation and social worker session. No correlation between age and operational variables was found., Conclusion: This novel operational protocol was successfully implemented and may serve as a framework for managing similar unpredictable sensitive events in the case of future need., (© 2024.

Background: C-reactive protein (CRP) blood level is associated with clinical outcomes of several diseases. However, the independent predictive role of CRP in the heterogeneous population of patients admitted to internal medicine wards is not known., Objectives: To determine whether single CRP levels at admission independently predicts clinical outcome and flow of patients in general medicine wards., Methods: This study comprised 275 patients (50.5% female) with a mean age of 68.25 ± 17.0 years, hospitalized with acute disease in a general internal medicine ward. The association between admission CRP levels and clinical outcomes including mortality, the need for mechanical ventilation, duration of hospitalization, and re-admission within 6 months was determined., Results: A significant association was found between CRP increments of 80 mg/L and risk for the major clinical outcomes measured. The mortality odds ratio (OR) was 1.89 (95% confidence interval (95%CI, 1.37-2.61, P < 0.001), mechanical ventilation OR 1.67 (95%CI, 1.10-2.34, P = 0.006), re-admission within 6 months OR 2.29 (95%CI, 1.66-3.15 P < 0.001), and prolonged hospitalization >7 days OR 2.09 (95%CI, 1.59-2.74, P < 0.001). Lower increments of10 mg/L in CRP levels were associated with these outcomes although with lower ORs. Using a stepwise regression model for admission CRP levels resulted in area under the receiver operating characteristics curves between 0.70 and 0.76 for these outcomes., Conclusions: A single admission CRP blood level is independently associated with major parameters of clinical outcomes in acute care patients hospitalized in internal medicine wards.

The adult form of mononucleosis caused by Ebstein-Barr virus (EBV) is different from the disease in children and adolescents. In most adults there is no pharyngitis or lymphadenopathy, fever is much more prolonged, abnormal liver function is frequent and lymphocytosis and the presence of atypical lymphocytes are not common. Such an atypical disease presentation often results in delayed diagnosis and unnecessary treatments. We describe 2 adults with such atypical presentations and complications of EBV infection.
