  • Spatio-temporal visual attention modelling of standard biometry plane-finding navigation. [Journal Article]
    Med Image Anal. 2020 Jun 20; 65:101762.Cai Y, Droste R, … Noble JA
  • We present a novel multi-task neural network called Temporal SonoEyeNet (TSEN) with a primary task to describe the visual navigation process of sonographers by learning to generate visual attention maps of ultrasound images around standard biometry planes of the fetal abdomen, head (trans-ventricular plane) and femur. TSEN has three components: a feature extractor, a temporal attention module (TA…
  • [Peripheral truncal blocks-Overview and assessment]. [Review]
    Anaesthesist. 2020 Jul 03 [Online ahead of print]Steinfeldt T, Kessler P, … Wiesmann T
  • By implementation of sonography for regional anesthesia, truncal blocks became more relevant in the daily practice of anesthesia and pain therapy. Due to visualized needle guidance ultrasound supports more safety and helps to avoid complications during needle placement. Additionally, complex punctures are possible that were associated with higher risk using landmarks alone. Next to the blocking o…
  • Boosting hydrogen evolution on MoS2 via co-confining selenium in surface and cobalt in inner layer. [Journal Article]
    Nat Commun. 2020 Jul 03; 11(1):3315.Zheng Z, Yu L, … Deng D
  • The lack of highly efficient, inexpensive catalysts severely hinders large-scale application of electrochemical hydrogen evolution reaction (HER) for producing hydrogen. MoS2 as a low-cost candidate suffers from low catalytic performance. Herein, taking advantage of its tri-layer structure, we report a MoS2 nanofoam catalyst co-confining selenium in surface and cobalt in inner layer, exhibiting a…
  • Flight Test Techniques for Quantifying Pitch Rate and Angle of Attack Rate Dependencies. [Journal Article]
    J Aircr. 2017 Nov; 54(6):2367-2377.Grauer JA, Morelli EA, Murri DG
  • Three different types of maneuvers were designed to separately quantify pitch rate and angle of attack rate contributions to the nondimensional aerodynamic pitching moment coefficient. These maneuvers combined pilot inputs and automatic multisine excitations, and were demonstrated with the subscale T-2 and Bat-4 airplanes using the NASA AirSTAR flight test facility. Stability and control derivati…
  • Minimally invasive techniques in rhinoplasty. [Journal Article]
    Curr Opin Otolaryngol Head Neck Surg. 2020 Jun 28 [Online ahead of print]Gassner HG, Magdum AA, Tasman AJ
  • CONCLUSIONS: A single incision endonasal approach, the subperichondrial and subperiosteal septal plane, the supraperichondrial plane over the cartilaginous dorsum, the subperiosteal plane over the bony dorsum, limited dorsal undermining with endoscopic visualization when feasible, conventional straight lateral osteotomy or percutaneous curved lateral osteotomy; percutaneous transverse osteotomy; conventional straight paramedian osteotomy; piezo and drill paramedian ostectomy; dorsal uncapping osteotomy; conventional rasp gross dorsal contouring; piezo or drill fine dorsal contouring; (cartilaginous) middle vault 'let down'; and minimal access subperiosteal turbinate bone resection were found to best fulfil the criteria of minimally invasive surgery. A classification system for the degree of minimally invasiveness of rhinoplasty techniques is proposed as a basis for discussion.
  • Inferior Hepatic Fissures: Anatomic Variants in Trinidad and Tobago. [Journal Article]
    Cureus. 2020 May 30; 12(5):e8369.Cawich SO, Gardner MT, … Naraynsingh V
  • Classic descriptions of the visceral surface of the human liver only define three fissures: transverse, sagittal and umbilical fissures. Any additional fissures that are present on the visceral surface of the liver are considered variant inferior hepatic fissures (IHFs). This study was carried out to document the prevalence of IHFs in the Eastern Caribbean. Knowledge of these variants is importan…
  • Weightbearing Forefoot Axial Radiography - Technical Description and Reproducibility Evaluation. [Journal Article]
    Rev Bras Ortop (Sao Paulo). 2020 Jun; 55(3):367-373.Sposeto RB, Sakaki MH, … Fernandes TD
  • Objective  The present study aims to describe a new weightbearing radiographic method to visualize the heads of the five metatarsals on the coronal plane, evaluating their accuracy through intraclass correlation coefficients. Methods  The subjects were evaluated, with weightbearing, with the ankle at 20 degrees of plantar flexion and the metatarsophalangeal joints at 10 degrees of extension, posi…
  • Evolution of lattice distortions in 4H-SiC wafers with varying doping. [Journal Article]
    Sci Rep. 2020 Jul 02; 10(1):10845.Mahadik NA, Das H, … Ruland GE
  • Lattice distortions (LD) in 4H-silicon carbide (SiC) wafers were quantified using synchrotron X-ray rocking curve mapping (RCM), and were resolved into their two components of lattice strain (Δd/d) and lattice plane curvature (LPC) for 150 mm diameter wafers. The evolution of these LDs were investigated for three sequential substrates from the same boule, one of which was the substrate reference,…
  • Covalent surface modifications and superconductivity of two-dimensional metal carbide MXenes. [Journal Article]
    Science. 2020 Jul 02 [Online ahead of print]Kamysbayev V, Filatov AS, … Talapin DV
  • Versatile chemical transformations of surface functional groups in 2D transition-metal carbides (MXenes) open up a new design space for this broad class of functional materials. We introduce a general strategy to install and remove surface groups by performing substitution and elimination reactions in molten inorganic salts. Successful synthesis of MXenes with O, NH, S, Cl, Se, Br, and Te surface…
  • The first 2 months of COVID-19 contact tracing in the Northern Territory of Australia, March-April 2020. [Journal Article]
    Commun Dis Intell (2018). 2020 Jul 02; 44Draper AD, Dempsey KE, … Krause VL
  • The Northern Territory (NT) Centre for Disease Control (CDC) undertook contact tracing of all notified cases of coronavirus disease 2019 (COVID-19) within the Territory. There were 28 cases of COVID-19 notified in the NT between 1 March and 30 April 2020. In total 527 people were identified as close contacts over the same period; 493 were successfully contacted; 445 were located in the NT and wer…
