Contact Force Estimation in Human–Robot Collaboration: A Case Study on Heavyweight Robotic Manipulators

open access: yesAdvanced Intelligent Systems, EarlyView.
The method presented in this paper provides a practical sensorless solution for estimating both contact force and contact location using only standard joint encoders and an available robot dynamic model. By reformulating the contact estimation problem using a single scalar equivalent contact parameter, the approach enables fast and robust computation ...

Insights From Unsteady Flow Analysis of Underdamped Slug Tests in Fractured Rock

open access: yesWater Resources Research, 2018
Slug tests generating oscillating (underdamped) responses are common in high‐transmissivity (T) zones, and the nature of the response depends on the plumbing of the test equipment and the formation properties.

Limited Agreement Between Perceptual and Physiological Heat Strain at Initial Stay Times for Continuous Work in the Heat Before Heat Alleviation Controls

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Accurate assessment of heat strain at initial stay time (IST; core temperature 38.0°C or Δ1.0°C above resting), when heat mitigation decisions are required, is critical for managing occupational heat exposure. We evaluated the relationship and agreement between physiological (Physiological Strain Index [PSI] and adaptive PSI [aPSI]

Numerical Calculation of Gas–Liquid Two-Phase Flow in Tesla Valve

open access: yesAerospace
In this paper, the gas–liquid two-phase flow within a Tesla valve under zero-gravity conditions is numerically studied. Based on the VOF model and the inlet two-phase separation method, the forward and reverse flow patterns and pressure drop changes in a

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

Experimental investigation of pressure disturbances influence on a parallel flow of viscous immiscible liquids in a T-shaped microchannel

open access: yesEPJ Web of Conferences, 2019
In the present paper pressure disturbances influence on parallel flow of immiscible liquids, viz. castor oil and paraffin oil, in a T-shaped microchannel with 320 um hydraulic diameter is studied experimentally.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Zuranolone: A case study in (regulatory) rush to judgement?

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Sage, in collaboration with Biogen, submitted a new drug approval for zuranolone for postpartum depression (PPD) and major depressive disorder (MDD) in December 2022. In August 2023, the US Food and Drug Administration granted approval for PPD but denied approval for MDD.

Inventory Replenishment and Transshipment for Distributed Autologous Cell Therapy Manufacturing Networks

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Autologous cell therapy (AuCT) manufacturing networks must balance two competing objectives: reducing cost and improving patient access to time‐sensitive therapy. This study compares three AuCT manufacturing network designs: a centralized network with a single manufacturing facility, a coordinated point‐of‐care (POC) network in which POCs can ...
