Robust Model Predictive Control for DAB Converters Using Extended Phase Shift Modulation With Minimum Backflow Power and ZVS Design

open access: yesIEEE Access
This paper introduces a method for deriving an optimal closed-form solution for extended phase shift (EPS) control of a dual active bridge (DAB) DC-DC converter, capable of achieving both minimum backflow power (MBP) and zero-voltage switching (ZVS ...

Experimental evaluation of resistojet thruster plume shields [PDF]

open access: yes
The exhaust of an engineering model resistojet has been investigated using rotary pitot probes and a rotary quartz crystal microbalance. The resistojet operated on CO2 propellant at a mass flow rate of 0.29 g/sec in both heated and unheated flows ...

The IceShark, an effective method for sampling plankton under sea ice

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Viscosity Reduction in Diluted Polyethylene Melts: A Comparative Study of Semiempirical, Viscoelastic, and Equation‐of‐State Modeling Frameworks

open access: yesPolymer Engineering &Science, EarlyView.
Schematic of the in‐line rheometry setup and the evaluation of three distinct modeling frameworks (semiempirical, viscoelastic, and EOS) to predict viscosity reduction in diluted polyethylene melts via time‐concentration superposition (Illustration generated via ChatGPT).

Hydraulic In Vitro Characterization of MR‐Conditional Blood Pumps

open access: yesArtificial Organs, EarlyView.
Cardiac surgery in neonates requires close placement of cardiopulmonary bypass machines due to limited blood volume, complicating MR compatibility. This study introduces three MR‐conditional blood pump prototypes. None interfered with MRI imaging, though RF‐related sensor effects remain untested.

Experimental and theoretical study of the smoke back-layering length in a tunnel with cross-passage: effects of longitudinal fire source locations

open access: yesRailway Engineering Science
The diversion effect caused by the linked structure in a metro tunnel with cross-passage complicates the impact of longitudinal fire source location on the smoke backflow layering behavior that has not been clarified, despite the fact that the scenario ...

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

open access: yesBrain Pathology, EarlyView.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Cannabigerol reverses mechanical allodynia through α2A‐adrenergic modulation of thalamocortical signaling in chemotherapy‐induced neuropathy

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Chemotherapy‐induced peripheral neuropathy (CIPN) is a prevalent and treatment‐resistant side effect of platinum‐based chemotherapy, characterised by mechanical allodynia. Cannabigerol (CBG), a non‐psychoactive cannabinoid, has shown antinociceptive potential, but its site and mechanism of action remain unclear.

Experimental study of two separating turbulent boundary layers [PDF]

open access: yes
A detailed study of two strong adverse pressure gradient flows, one with a free-stream velocity of 35 m/sec, at throat (producing a Re sub theta of 27000 at detachment) and another with free-stream velocity of 22 m/sec, at throat (producing a Re sub ...

Primary cardiac T‐cell rich large B‐cell lymphoma causing aortic stenosis with metastasis in a Warmblood

open access: yesEquine Veterinary Education, EarlyView.
Summary An 18‐year‐old Warmblood mare was presented to the Royal Veterinary College Equine Referral Hospital for investigation of progressive periocular and facial swelling, weight loss and tachycardia. Physical examination additionally identified bilateral pansystolic (grade 5/6 basilar left‐sided, 2/6 right‐sided), cardiac murmurs, submandibular ...
