In the eastern hardwood forests of North America ice storms are an important disturbance event. Ice storms strongly influence community dynamics as well as urban infrastructure via catastrophic branch failure; further, the severity and frequency of ice storms are likely to increase with climate change. However, despite a long-standing interest into the effects of freezing rain on forests, the p...

OBJECTIVES/HYPOTHESIS To examine by intraoperative electric stimulation which peripheral facial nerve (FN) branches are functionally connected to which facial muscle functions. STUDY DESIGN Single-center prospective clinical study. METHODS Seven patients whose peripheral FN branching was exposed during parotidectomy under FN monitoring received a systematic electrostimulation of each branch...

Biomass-based pellet is an important source of renewable energy. In this study, to obtain the high-quality fuel via densification pruned branches fruit trees, we investigated optimization blending ratios for different raw materials using from jujube (Ziziphus jujuba Mill.), which a widely distributed waste biomass resource in China. Through characterization and pellets, effects on storage, tran...

It is well-known that G3i, the sequent calculus for intuitionistic propositional logic where weakening and contraction are absorbed into the rules, is not terminating. Indeed, due to the contraction in the rule for left implication, the naı̈ve goal-oriented proof-search strategy, consisting in applying the rules of the calculus bottom-up until possible, can generate branches of infinite length. ...

BACKGROUND Information of tumor vascular architecture and hemodynamics is important in treating patients with head and neck tumors (HNTs). The purpose of this study is to investigate the feasibility of non-contrast-enhanced four-dimensional magnetic resonance angiography (non-CE 4DMRA) using arterial spin labeling for anatomical and hemodynamic evaluation of vascularity of head and neck tumors....

BACKGROUND Precise noninvasive evaluation of pulmonary artery (PA) morphology is extremely important for medical and surgical management of patients with cyanotic heart disease. In this study, the accuracy of two-dimensional echocardiography combined with color Doppler flow mapping to assess the size, stenosis, and atresia of the major PA branches was examined using a new parasternal approach. ...

Starving tumors eat metabolic enzyme Xia et al. describe a way to force cancer cells to destroy a key metabolic enzyme they need to survive. Autophagy helps cancer cells survive the stressful environment inside a tumor. However, blocking the process doesn’t kill cancer cells, so researchers have been looking for a way to make cells vulnerable to autophagy shutdown. Xia et al. used an ovarian ca...

The branching of dendrites and axons is a key determinant of neural circuit formation. In this issue of Neuron, Kawabe et al. demonstrate that the ubiquitin ligase Nedd4 promotes the branching of developing dendrites by targeting the small G protein Rap2. In a complementary study, Drinjakovic et al. show that Nedd4 promotes the branching of developing axons by ubiquitinating a different target,...
