Ultrathin ferroic HfO-ZrO superlattice gate stack for advanced transistors.

With the scaling of lateral dimensions in advanced transistors, an increased gate capacitance is desirable both to retain the control of the gate electrode over the channel and to reduce the operating voltage. This led to a fundamental change in the gate stack in 2008, the incorporation of high-dielectric-constant HfO (ref. ), which remains the material of choice to date.

Evolutionary de Winter pattern: from STEMI to de Winter ECG-a case report.

The de Winter electrocardiography (ECG) pattern is a sign that implies proximal left anterior descending coronary artery occlusion in patients with chest pain. We report a case of a 34-year-old man with a history of smoking who presented to the local emergency department with a 49 min history of chest pain. The first ECG of the patient indicated that ST-segment elevation was noted in the lead V2-V4; 57 min later, a second ECG revealed a typical de Winter syndrome when the patient was transferred to the emergency chest pain centre of our hospital.

Microsurgical Resection of Cervical Spinal Cord Arteriovenous Malformations: Report of 6 Cases.

Objective: To summarize the experience in microsurgical resection of cervical spinal cord arteriovenous malformation (AVM).

Methods: Six patients undergoing microsurgical resection of cervical intramedullary AVM in the Third Affiliated Hospital of Sun Yat-sen University, China, between March 2005 and March 2015 were reviewed retrospectively, and their clinical manifestations, imaging data, surgical treatment, and results of long-term follow-up were analyzed.

Results: Of the 6 patients who underwent AVM resection, 2 had compact AVMs and 4 had diffuse AVMs.

The complete mitochondrial genome of the Black-spot tuskfish (Choerodon schoenleinii).

Choerodon schoenleinii, a critically endangered ocean fish, is also a highly prized commercial fish. In this study, we present the complete mitochondrial genome of C. schoenleinii based on NGS.

The complete mitochondrial genome of the Aluterus monoceros.

The complete mitochondrial genome of Aluterus monoceros (A. monoceros) has been sequenced. The mitochondrial genome of A.

The complete mitochondrial genome of Cheilinus undulates based on high-throughput sequencing technique.

Cheilinus undulatus is a Critically Endangered ocean fish, which is also a higher level predator in coral reef. The complete mitochondrial genome of Cheilinus undulatus has been sequenced by high-throughput sequencing technology. According to the results, the mitochondrial genome of Cheilinus undulatus is 17,184 bp long and consists of 38 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region.
