Mert Korkali, Jason G Veneman, Brian F Tivnan, James P Bagrow, Paul D H Hines
Increased interconnection between critical infrastructure networks, such as electric power and communications systems, has important implications for infrastructure reliability and security. Others have shown that increased coupling between networks that are vulnerable to internetwork cascading failures can increase vulnerability. However, the mechanisms of cascading in these models differ from those in real systems and such models disregard new functions enabled by coupling, such as intelligent control during a cascade...

A meal detection and meal size estimation algorithm is developed for use in artificial pancreas (AP) control systems for people with type 1 diabetes. The algorithm detects the consumption of a meal and estimates its carbohydrate (CHO) amount to determine the appropriate dose of insulin bolus for a meal. It can be used in AP systems without manual meal announcements, or as a safety feature for people who may forget entering meal information manually. Using qualitative representation of the filtered continuous glucose monitor signal, a time period labeled as meal flag is identified...

REVIEW
Mert Burak Ozturk, Yinghui Li, Vinay Tergaonkar
The telomerase ribonucleoprotein complex has a pivotal role in regulating the proliferation and senescence of normal somatic cells as well as cancer cells. This complex is comprised mainly of telomerase reverse transcriptase (TERT), telomerase RNA component (TERC) and other associated proteins that function to elongate telomeres localized at the end of the chromosomes. While reactivation of telomerase is a major hallmark of most cancers, together with the synergistic activation of other oncogenic signals, deficiency in telomerase and telomeric proteins might lead to aging and senescence-associated disorders...

The effect of healthy aging on cognitive control of irrelevant visual information was investigated by using event-related potentials. Participants performed a spatial cuing task where an irrelevant color cue that was either contingent (color search) or noncontingent (shape search) on the attentional set was presented before a target with different stimulus-onset asynchronies. In the contingent condition, attentional capture appeared independent of age and persisted over the stimulus-onset asynchronies but was markedly pronounced for elderly people...

BACKGROUND: Acute cholecystitis (AC) is a common emergency seen by general surgeons. Optimal treatment is laparoscopic cholecystectomy (LC); however, in cases where surgery cannot be performed due to high risk of morbidity and mortality, such as in elderly patients with comorbid diseases, other treatment modalities may be used. Percutaneous cholecystostomy (PC) is one alternative method to treat AC. PC can be used to provide drainage of the gall bladder and control infection. Subsequently, interval cholecystectomy can be performed when there are better conditions...

Several pathogens have been suspected of playing a role in the pathogenesis of schizophrenia. Chronic inflammation has been proposed to occur as a result of persistent infection caused by Chlamydophila pneumoniae cells that reside in brain endothelial cells for many years. It was recently hypothesized that brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) may play prominent roles in the development of schizophrenia. NT-3 and BDNF levels have been suggested to change in response to various manifestations of infection...

The sustainable use of agricultural lands is significantly affected by the implemented management and land processing methods. In sugar beet and wheat cropping, because the agronomic characteristics of plants are different, the tillage methods applied also exhibit significant variability. Soil quality concept is used, as a holistic approach to determining the effects of these applications on the sustainable use of soil. Agricultural soil quality evaluation is essential for economic success and environmental stability in rapidly developing regions...

Aligning images in a mid-space is a common approach to ensuring that deformable image registration is symmetric - that it does not depend on the arbitrary ordering of the input images. The results are, however, generally dependent on the mathematical definition of the mid-space. In particular, the set of possible solutions is typically restricted by the constraints that are enforced on the transformations to prevent the mid-space from drifting too far from the native image spaces. The use of an implicit atlas has been proposed as an approach to mid-space image registration...

Congenital myasthenic syndromes (CMS) are a heterogeneous group of diseases of the neuromuscular junction caused by compromised synaptic transmission. Clinical features include early-onset weakness of limbs and oculobulbar muscles resulting in hypotonia, bulbar paresis, ptosis, and hypoventilation. The first dropped head syndrome in children were detected in 2 patients with LMNA and SEPN1 mutations. We report a 17-month-old boy with dropped head and limb-girdle weakness, who had no ptosis or ophthalmoplegia at presentation...
