Photon-counting single-pixel camera based on a fast spinning coding disk.

Spinning coding masks, recognized for their fast modulation rate and cost-effectiveness, are now often used in real-time single-pixel imaging (SPI). However, in the photon-counting regime, they encounter difficulties in synchronization between the coding mask patterns and the photon detector, unlike digital micromirror devices. To address this issue, we propose a scheme that assumes a constant disk rotation speed throughout each cycle and models photon detection as a non-homogeneous Poisson process (NHPP).

Empiric embolization by vasospasm therapy for acute lower gastrointestinal bleeding: a preliminary report.

To report the preliminary result of empiric embolization for angiographycally-negative lower gastrointestinal bleeding (LGIB) by using the pharmaco-induced vasospasm technique with or without the adjunctive use of intra-arterial multi-detector computed tomography (MDCT). 23 LGIB patients with positive MDCT findings but negative angiographic results underwent empiric pharmaco-induced vasospasm therapy. The presumed bleeding artery was semi-selectively catheterized, and a segment of bowel was temporarily spasmed with bolus injection of epinephrine and immediately followed by 4-h' vasopressin infusion.

Prognostic Evaluation of Conversion Therapy following Hepatic Arterial Infusion Chemotherapy or Immunotherapy in Patients with Advanced or Transarterial Chemoembolization Unsuitable Intermediate-Stage Hepatocellular Carcinoma: A Retrospective Cohort Study.

Introduction: Patients with advanced-stage or intermediate-stage hepatocellular carcinoma (HCC) unsuitable for transarterial chemoembolization (TACE) had poor prognoses. Recent advancements in hepatic arterial infusion chemotherapy (HAIC) and immune checkpoint inhibitors (ICIs) have demonstrated higher tumor response rates, which improved overall survival (OS). HAIC achieves an OS rate of approximately 14.

Efficient extraction of light-colored lignin from bamboo by p-toluenesulfonic acid assisted tetrahydrofurfuryl alcohol aqueous solution.

Acidic hydrotropes exhibit effective performance in fractionating the constituents of lignocellulosic biomass owing to their amphiphilic characteristics. However, the requirement for excessively high concentrations may lead to the condensation and aggregation of lignin. In this case, bamboo was extracted with 70 % (w/v) tetrahydrofurfuryl alcohol (THFA) aqueous solution containing 5-20 % (w/v) p-toluenesulfonic acid (pTsOH) at 90-120 °C for 1-4 h.

A molecular mechanism underlies grass carp (Ctenopharyngodon idella) TARBP2 regulating PKR-mediated cell apoptosis.

Interferon-inducible double-stranded RNA-dependent protein kinase (PKR) is one of the key antiviral arms in the innate immune system. The activated PKR performs its antiviral function by inhibiting protein translation and inducing apoptosis. In our previous study, we identified grass carp TARBP2 as an inhibitor of PKR activity, thereby suppressing cell apoptosis.

Simultaneous imaging and element differentiation by energy-resolved x-ray absorption ghost imaging.

Based on the x-ray absorption edges of different elements, we simultaneously image and distinguish the composition of three differently shaped components of an object by using energy-resolved x-ray absorption ghost imaging (GI). The initial x-ray beam is spatially modulated by a series of Hadamard matrix masks, and the object is composed of three pieces of Mo, Ag, and Sn foil in the shape of a triangle, square, and circle, respectively. The transmitted x-ray intensity is measured by an energy-resolved single-pixel detector with a spectral resolution better than 0.

Enhancing fuel characteristics and combustion performance of cellulose-rich straws through CO-assisted torrefaction.

Cellulose-rich straws of corn and rice were torrefied under carbon dioxide, and the fuel characteristics and combustion performance of the obtained biochar were investigated. A high severity resulted in surface collapse, greater pore volume, elimination of oxygen, elevated calorific value, and improved hydrophobicity in biochar. Following carbon dioxide torrefaction, the cellulose content in solid biochar experienced a slight decrease when the temperature was raised to 220 °C for longer residence durations.
