Objective:The objective of this study was to compare cardiac transplant operative and postoperative courses of patients with failed Fontan physiology who were initially palliated with a Norwood(FFN)to those without a prior Norwood(FF).Methods:A single-institution retrospective review of all patients with Fontan failure who under-went cardiac transplantation from 2003–2021 was completed-22 underwent prior Norwood(FFN)and 11 did not(FF).descriptive and inferential statistics were calculated for operative course and patient ***:The operative course of the FFN cohort appeared to be more complex(not statistically significant,but clinically relevant)-this group exclusively experienced sternal re-entry events(3 of 22 patients)and concomitant neo-aor-tic reconstruction(6 patients),had a longer duration of surgery(median of 682 min vs.575.5 min),more time on circulatory arrest(median of 25.5 min vs.12.5 min),and more frequent use of open sternal management[50%of patients(11/22)vs.27.3%of patients(3/11)].Postoperatively,these patients underwent more mediastinal explora-tions[other than sternal closure;40.9%of patients(9/22)vs.18.2%of patients(2/11)],spent more time on mechanical ventilation(median of 5 days vs.2 days),had a longer length of stay(median of 30 days vs.19 days),and required more catheter-based re-interventions[22.7%of patients(5/22)vs.9.1%of patients(1/11)].Conclu-sion:Although underpowered,our results suggest that the operative course of FFN patients is more challenging,based mostly on neo-aortic arch *** turn,this likely leads to a more complex postoperative *** are currently collaborating with other institutions to increase the cohort size and power of the study.

In[***.A 107012427(2023)],Baldwin and Jones prove that Uhlmann–Jozsa’s fidelity between two quantum statesρandσ,i.e.,F(ρ,σ)=(Tr√√ρσ√ρ)^(2),can be written in a simplified form as F(ρ,σ)=(Tr√ρσ)^(2).In this article,we give an alternative proof of this result,using a function power series expansion and the properties of the trace *** approach not only reinforces the validity of the simplified expression but also facilitates the exploration of novel dissimilarity functions for quantum states and more complex trace functions of density operators.

Two-dimensional(2d)transition metal dichalcogenides(TMd)are atomically thin semiconductors with promising optoelectronic applications across the visible ***,their intrinsically weak light absorption and the low photoluminescence quantum yield(PlQY)restrict their performance and potential use,especially in ultraviolet(UV)wavelength light *** dots(Qd)derived from 2d materials(2d/Qd)provide efficient light absorption and emission of which energy can be tuned for desirable light *** this study,we greatly enhanced the photon absorption and PlQY of monolayer(1l)tungsten disulfide(wS_(2))in the UV range via hybridization with 2d/Qd,particularly titanium nitride MXene Qd(Ti_(2)N MQd)and graphitic carbon nitride Qd(GCNQd).with the hybridization of MQd or GCNQd,1lwS_(2)showed a maximum Pl enhancement by 15 times with 300 nm wavelength excitation,while no noticeable enhancement was observed when the excitation photon energy was less than the bandgap of the Qd,indicating that UV absorption by the Qd played a crucial role in enhancing the light emission of 1l-wS_(2)in our 0d/2d hybrid *** findings present a convenient method for enhancing the photo-response of 1l-wS_(2)to UV light and offer exciting possibilities for harvesting UV energy using 1l-TMd.

Modulation of human global/local perception by low spatial frequency filtering

引用

Chinese Science Bulletin 2003年第21期48卷 2336-2339页

作者： HANShihui J.A.weaver S.O.Murray KANGXiaojian e.w.yund.d.l.woods departmentofPsychology CenterforBrainandCognitiveSciencesPekingUniversityBeijing100871China departmentofNeurology UniversityofCaliforniaatDavisVANorthernCaliforniaSystemofClinicsDavisCA95616USA

we investigated the effect of low spatial fre-quency (SF) filtering on neural substrates underlying global and local processing in the peripheral vision by measuring hemodynamic responses with functional magnetic resonance imaging (fMRI). Subjects identified global or local shapes of compound letters that were either broadband in spatial- frequency spectrum or contrast balanced (CB) to removed low SFs and displayed randomly in the left or right visual fields. Attention to both broadband and CB global shapes generated stronger activation over the medial occipital cor-tex relative to local attention. lateralized activations in association with global processing were observed over the right temporal-parietal junction for broadband stimuli whereas over the right fusiform gyrus for CB stimuli. Atten-tion to CB local shapes resulted in activations in the medial frontal cortex, bilateral inferior frontal and superior tempo-ral cortices. The results were discussed in terms of the competition between global and local information in determining brain activations in association with global/local processing of compound stimuli.
