Light correcting light with nonlinear optics

Structured light, where complex optical fields are tailored in all their degrees of freedom, has become highly topical of late, advanced by a sophisticated toolkit comprising both linear and nonlinear *** undesired structure from light is far less developed, leveraging mostly on inverting the distortion,e.g., with adaptive optics or the inverse transmission matrix of a complex channel, both requiring that the distortion be fully characterized through appropriate measurement. We show that distortions in spatially structured light can be corrected through difference-frequency generation in a nonlinear crystal without any need for the distortion to be known. We demonstrate the versatility of our approach using a wide range of aberrations and structured light modes, including higher-order orbital angular momentum(OAM) beams,showing excellent recovery of the original undistorted field. To highlight the efficacy of this process, we deploy the system in a prepare-and-measure communications link with OAM, showing minimal cross talk even when the transmission channel is highly aberrated, and outline how the approach could be extended to alternative experimental modalities and nonlinear processes. Our demonstration of light-correcting light without the need for measurement opens an approach to measurement-free error correction for classical and quantum structured light, with direct applications in imaging, sensing, and communication.

Restricted fetal growth(RFg)is a leading contributor to perinatal mortality and has been associated with gestational exposure to air pollution,such as fine particulate matter(PM_(2.5)),nitrogen dioxide(NO2),and polycyclic aromatic hydrocarbons(PAHs).This study examines the association between trimester-specific and weekly means of air pollution throughout gestation and placental inflammatory markers at *** a prospective cohort study of 263 pregnant women in Rochester,NY,we measured interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)in placental tissue and estimated gestational exposure to PM_(2.5)and NO_(2)using a high-resolution spatial-temporal *** to PAHs was estimated using urinary 1-hydroxypyrene(1-OHP)concentrations collected once per *** distributed lag models with a penalized spline function,each interquartile range(2.6μg/m^(3))increase in PM_(2.5)concentration during gestational weeks 6−11 was associated with decreased placental IL-6 levels(−22.2%,95%CI:−39.0%,−0.64%).Using multiple linear regression models,each interquartile range increase of 1-OHP was associated with an increase in TNF-αin the first trimester(58.5%,95%CI:20.7%,74.2%),third trimester(22.9%,95%CI:0.04%,49.5%),and entire pregnancy(29.6%,95%CI:3.9%,60.6%).Our results suggest gestational exposure to air pollution may alter the inflammatory environment of the placenta at delivery.

Numerical simulation on inclusion transport in continuous casting mold

引用

Journal of University of Science and Technology Beijing 2006年第4期13卷 293-300页

作者： Lifeng Zhang Brian g thomas Department of Materials Science ＆ Engineering Norwegian University of Science ＆ Technology （NTNU） Alfred Getz vei 2 N-7491 Trondheim Norway University of Illinois at Urbana-Champaign 1206 W. Green St. Urbana IL 61801 USA

Turbulent flow, the transpor＇t of inclusions and bubbles, and inclusion removal by fluid flow, transport and by bubble flotation in the strand of the continuous slab caster are investigated using computational models, and validated through comparison with plant measurements of inclusions. Steady 3-D flow of steel in the liquid pool in the mold and upper strand is simulated with a finitedifference computational model using the standard k-εturbulence rondel. Trajectories of inclusions and bubhles tire calculated by integrating each local velocity, considering its drag and buoyancy forces, A ＂random walk＂ model is used to incorporate the effect of turbulent fluctuations on the particle motion. The attachment probability of inclusions on a bubble surface is investigated based on fundamental fluid flow simulations, incorporating the turbulent inclusion trajectory and sliding time of each individual inclusion along the bubble surface as a function of particle and bubble size. The chunge in inclusion distribution due to removal by bubble transport in the mold is calculated based on the computed attachment probability of inclusions on each bubble and the computed path length of the bubbles. The results indicate that 6%-10% inclusions are removed by fluid flow transport. 10% by bubble flotation, and 4% by entrapment to the submerged entry nozzle （SEN） walls. Smaller bubbles and larger inclusions have larger attachment probabilities. Smaller bubbles are more efficient for inclusion removal by bubble flotation, so Inng as they are not entrapped in the solidifying shell A larger gas flow rate favors inclusion removal by bubble flotation. The optimum bubble size should be 2-4mm.

Management of a Huge Ovarian Cyst in Pregnancy at the Douala general Hospital, Cameroon: A Case Report and Review of the Literature

引用

Advances in Reproductive Sciences 2024年第3期12卷 165-178页

作者： Fidelia Mbi Kobenge Felix-Adolphe Elong Emenguele Pascale Mpono thomas Obinchemti Egbe Department of Obstetrics and gynecology Douala General Hospital Douala Cameroon Faculty of Health Sciences University of Bamenda Bamenda Cameroon Faculty of Health Sciences University of Buea Buea Cameroon Faculty of Medicine and Biomedical Sciences University of Yaound 1 Yaound Cameroon Department of Obstetrics and gynecology CHRACERH Yaound Cameroon

Background: Ovarian cysts in pregnancy are common and are usually small benign functional cysts (corpus luteum and theca-lutein cysts) that usually resolve spontaneously between 14 and 16 weeks of gestation. However, large ovarian cysts are rare in pregnancy, with an incidence of 0.2% - 2%, and most of them are benign. The first-line diagnostic modality is ultrasonography. Complications of ovarian cysts in pregnancy include miscarriage, ovarian torsion, cyst rupture, etc. Laparotomy is the treatment modality commonly used in our setting, and histopathologic diagnosis is important for the prognosis of the treatment. Case Presentation: MC is a 32-year-old g3P2002 married housewife of the Bakweri tribe who was referred to our department because of progressive abdominal discomfort and shortness of breath for 1 month’s duration. Her medical history is consistent with two normal vaginal deliveries at term and the use of implants (for contraception) until one month prior to the index pregnancy. Her booking visit was at 16 weeks gestation at a primary (missionary) healthcare facility, and she underwent ultrasonography and was diagnosed with a singleton viable intrauterine pregnancy and a simple septate cystic mass measuring 17 cm situated on top of the uterus, appearing to originate from the left ovary. She was referred to seek the expertise of an obstetrician-gynecologist, but she came to our department at 35 weeks gestation and underwent cesarean birth at 37 weeks gestation. In the pathological review, serous cystadenoma was diagnosed, and there were no positive findings in peritoneal cytology. Conclusion: The ultrasonographic diagnosis of the huge ovarian cyst in the index case was after 16 weeks gestation because of her late booking visit at 16 weeks gestation. The index case deferred referral to the obstetrician because of a lack of finances, came to our department at 35 weeks gestation because of abdominal pain that may have resulted from a torsion of the ovarian cyst

A dye-sensitized photocatalyst combining Pt-loaded TiO_(2)and Ru(Ⅱ)tris-diimine sensitizer(RuP)was constructed and its activity for photochemical hydrogen evolution was compared with that of Pt-intercalated HCa_(2)Nb_(3)O_(10)*** the sacrificial donor ethylenediaminetetraacetic acid(EDTA)disodium salt dihydrate was used,RuP/Pt/TiO_(2)showed higher activity than RuP/Pt/HCa_(2)Nb_(3)O_(10).In contrast,when NaI(a reversible electron donor)was used,RuP/Pt/TiO_(2)showed little activity due to back electron transfer to the electron acceptor(I3-),which was gener-ated as the oxidation product of I-.By modification with anionic polymers(sodium poly(styrenesulfonate)or sodium polymethacrylate)that could inhibit the scavenging of conduction band electrons by I3-,the H_(2)production activity from aqueous NaI was improved,but it did not exceed that of RuP/Pt/HCa_(2)Nb_(3)O_(10).Transient absorption measurements showed that the rate of semiconductor-to-dye back electron transfer was slower in the case of TiO_(2)than HCa_(2)Nb_(3)O_(10),but the electron transfer reaction to I3-was much *** results indicate that Pt/TiO_(2)is useful for reactions with sacrificial reductants(e.g.,EDTA),where the back electron transfer reaction to the more reducible product can be ***,more careful design of the catalyst will be nec-essary when a reversible electron donor is employed.
