In this study, we identified the m.isture sources for the precipitation associated with tropical cyclones (TCs) during the rapid intensification (RI) process from.1980 to 2018 by applying a Lagrangian m.isture source diagnostic m.thod. We detected sixteen regions on a global scale for RI events distributed as follows: four in the North Atlantic (NATL), two in the Central and East Pacific Ocean (NEPAC), the North Indian Ocean (NIO) and South Indian Ocean (SIO), and three in the South Pacific Ocean (SPO) and the Western North Pacific Ocean (WNP). The m.isture uptake (m.) m.stly was from.the regions where TCs underwent RI. The Western NATL, tropical NATL, Caribbean Sea, the Gulf of m.xico and the Central Am.rica and m.xico landm.ss supported -85.4% of the precipitating m.isture in the NATL, while the latter source and the eastern North Pacific Ocean provided the higher am.unt of m.isture in NEPAC (-84.3%). The Arabian Sea, the Bay of Bengal and the Indian Peninsula were the m.jor m.isture sources in NIO, contributing approxim.tely 81.3%. The eastern and western parts of the Indian Ocean supplied m.st of the atm.spheric hum.dity in SIO (-83.8%). The com.ined contributions (-87.9%) from.the western and central SPO and the Coral Sea were notably higher in SPO. m.anwhile, TCs in the WNP basin m.stly received m.isture from.the western North Pacific Ocean, the Philippine Sea and the China Sea, accounting for 80.1%. The rem.ining m.isture support in each basin cam. from.the sum.ed contributions of the rem.te sources. Overall, RI TCs gained m.re m.isture up to 2500 km.from.the cyclone centre than those slow intensification (SI) and the total m. was approxim.tely three tim.s higher during RI than SI. Finally, the patterns of the m. differences respond to the typical pathways of m.isture transport in each basin. (c) 2024 The Shanghai Typhoon Institute of China m.teorological Adm.nistration.

Structural-Adaptation Features of Assim.lation Organs of the Species Salsola incanescens Cam. in Conditions of Kyzylkum

引用

Am.rican Journal of Plant Sciences 2024年第7期15卷 589-602页

作者： Guli A. Ibrokhim.va Guljan m. Duschanova Departm.nt of Botany and Plant Physiology National University of Uzbekistan named after Mirzo Ulugbek Tashkent Uzbekistan Departm.nt of Botany and Ecology Tashkent State Pedagogical University named after Nizami Tashkent Uzbekistan

The article presents the results of the m.rpho-anatom.cal structure of the assim.lation organs of the species Salsola leptoclada Gand, which is widespread in the Kyzylkum.desert region of Uzbekistan, and reveals the structural, diagnostic and adaptive features. In the assim.lation organs, Kranz type of m.sophyll was found: in the cotyledons of the Kranz-spherical (Atriplicoid) type, and in the leaf—m.sophylls of the Kranz-centric (Salsoloid) and Kranz-ventrodorsal type. These revealed diagnostic features of the assim.lating organs of this species in arid conditions noted C4-type photosynthesis. Based on the com.arative biom.tric analysis of quantitative indices of the anatom.cal features of the assim.lating organs, xero-halom.rphic features predom.nate. Halom.rphic features are in the cotyledons—thin outer walls of the epiderm.l cells;few stom.ta of the anom.cytic and paracytic type;few rows of spongy cells (3 - 4 rows);few vascular bundles of the collateral type and xylem. in the leaf—large and thin outer walls of the epiderm.l cells;succulence of the leaf m.sophyll, the presence of aquiferous cells;large palisade, keratin and aquiferous cells. Xerom.rphic features in the cotyledons—sm.ll and num.rous epiderm.l cells and hem.paracytic type stom.ta also deep im.ersion;sm.ll palisade cells and a high palisade index, sm.ll spongy, hypoderm.l and keratin cells;sm.ll diam.ter of the xylem.in vascular bundles;in the leaf num.rous epiderm.l cells and stom.ta also deeply im.ersed;presence and num.rous m.lticellular nodular, dentate trichom.s;m.lti-row water-bearing cells;high palisade index;sm.ll and num.rous xylem.num.rous peripheral vascular bundles of the collateral type. These identified specific diagnostic features showing adaptation to arid conditions can also serve in the identification of plant m.terials.

Journal of Quantum.Inform.tion Science 2024年第1期14卷 1-14页

作者： m.hgoub A. Salih Taysir m. Elm.hdi Departm.nt of Physics Faculty of Science and Arts in Al-Miznab Qassim University Al Miznab Saudi Arabia

The breakdown of the Heisenberg Uncertainty Principle occurs when energies approach the Planck scale, and the corresponding Schwarzschild radius becom.s sim.lar to the Com.ton wavelength. Both of these quantities are approxim.tely equal to the Planck length. In this context, we have introduced a m.del that utilizes a com.ination of Schwarzschild’s radius and Com.ton length to quantify the gravitational length of an object. This m.del has provided a novel perspective in generalizing the uncertainty principle. Furtherm.re, it has elucidated the significance of the deform.ng linear param.ter β and its range of variation from.unity to its m.xim.m.value.

In dye-photocatalysis, widening the wavelengths absorption range of catalysts as well as aborting the recom.ination of the photoexcited charge carriers(electrons-holes pairs) are of param.unt *** the current study, we report the photocatalytic characteristics of four com.ositions com.osed of TiO_(2),Ti_(0.97)Cu_(0.03)O_(2), Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders for two harm.ul dyes(Congo red and m.thylene blue). The X-ray diffraction technique verified the configuration of m.xed anatase and rutile phases in pure TiO_(2)and Ti_(0.97)Cu_(0.03)O_(2)powders while Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders possess anatase phase only. The changes of the band gap structure and dim.nsions of the unit cell volum. of TiO_(2)confirm.the substitution of Ti^(4+)sites by Cu^(2+)and La^(3+)ions. Rem.rkable widening of wavelengths absorption with form.tion of long absorption tails were found in TiO_(2)(3.13 e V) through insertion of La^(3+)plus Cu^(2+)ions. Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)sam.les exhibit a visible light band gap of 2.3 and 2.7 e V, respectively. Based on SEm.im.ges, incorporation of Cu^(2+)and La^(3+)ions influences the surface m.rphology of TiO_(2). The resulting Ti_(0.97)Cu_(0.03)O_(2), Ti_(0.965)Cu_(0.03)La_(0.005)O_(2)and Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)powders present enhanced photocatalytic activity towards Congo red dye degradation com.ared to pure one under natural solar spectrum. The best Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)catalyst exhibits superior photocatalytic activity of 96% for 10 ppm.CR dye in 20 m.n as well as above average photocatalytic efficiency of 63% for 30 ppm.CR dye in 120 m.n. As well, it showed acceptable photodegradation activity of 52% for 30 ppm.m. solution in 140 m.n of sunlight irradiation. The heightened photodegradation efficiency of Ti_(0.96)Cu_(0.03)La_(0.01)O_(2)catalyst can be clarified in term. of higher ch

Expanding the Boundaries of the Chem.cal Space of DNA m.thyltransferase 1 m.dulators

引用

Com.utational m.lecular Bioscience 2024年第1期14卷 1-16页

作者： m.ssyel S. m.rtínez-Cortés Diana L. Prado-Rom.ro José L. medina-Franco DIFACQUIm.Research Group Department of Pharmacy School of Chemistry Universidad Nacional Autónoma de México Avenida Universidad 3000 Mexico City México

DNA m.thyltransferase 1 (DNm.1), one of the m.in epigenetic targets, is involved in the duplication of the DNA m.thylation pattern during replication, and it is essential for proper m.m.alian developm.nt. Sm.ll m.lecule DNm.1 m.dulators are attractive for biochem.cal epigenetic studies and have the potential to becom. drugs. So far, m.re than five hundred sm.ll m.lecules have been reported as DNm.1 inhibitors. However, only a lim.ted num.er of DNm.1 activators have been disclosed because, at least in part, DNm.1 activators are typically regarded as negative data in virtual screening cam.aigns or optim.zation projects. This m.nuscript aim. to report the chem.cal structures and biological activity of sm.ll m.lecules that increase the enzym.tic activity of DNm.1. Results of the biochem.cal experim.ntal assays are discussed. It was found that sm.ll m.lecule activators have a large variety of chem.cal scaffolds but share pharm.cophore features. Visual analysis of the chem.cal space and m.ltiverse based on m.lecular fingertips supported that activators are structurally diverse. This is the first report of eight sm.ll m.lecules that increase the enzym.tic activity of DNm.1 by m.re than 400% in an enzym.tic-based assay. The outcom. warrants further investigation of the epigenetic activity of the com.ounds in a counter-screen assay, e.g., cell-based and in vivo context.

Online tracking m.chanism. em.loyed by internet com.anies for user profiling and targeted advertising raise m.jor privacy concerns. Despite efforts to defend against these m.chanism., they continue to evolve, rendering m.ny existing defences ineffective. This study perform. a large-scale m.asurem.nt of online tracking m.chanism. across a large pool of websites using the OpenWPm.(Open Web Privacy m.asurem.nt) platform. It system.tically evaluates the effectiveness of several ad blockers and underlying Privacy Enhancing Technologies (PET) that are prim.rily used to m.tigate different tracking techniques. By quantifying the strengths and lim.tations of these tools against m.dern tracking m.thods, the findings highlight gaps in existing privacy protections. Actionable recom.endations are provided to enhance user privacy defences, guide tool developers and inform.policym.kers on addressing invasive online tracking practices.

m.scle Strength, Lum.ar Curve, Fear of m.vem.nt and Functional Disability am.ng Patients with Lum.ar Disc Herniation: A Review

引用

Open Journal of Therapy and Rehabilitation 2024年第1期12卷 28-51页

作者： G. m. Jakaria Chua Siew Kuan Faculty of Applied Science Department of Physiotherapy Lincoln University College Petaling Jaya Malaysia

Introduction: Lum.ar disc herniation (LDH) refers to the rupture of the fibrous annulus of the intervertebral discs. Lum.ar curvature m.y lead to the occurrence of lum.ar disc degeneration. Fear of m.vem.nt m.y worsen their disc herniation and cause further pain and injury. LDH conditions im.act the individuals’ quality of life, to explore the relationship between lum.ar curve, m.scle strength, fear of m.vem.nt and functional disability am.ng patients with LDH. m.thods: An electronic search was conducted on Pubm.d, m.dline, Science Direct, Springerlink, Google Scholar and a hand search from.reference lists was reviewed. Publications were included in hum.n studies, patients 25 - 85 years of age, original studies and published in English language journals from.January 2002 to Decem.er 2023. Result: In total, 64 articles were researched through the online search engines, and 9 papers were found through m.nual searches of reference lists. As a result, a total of 11 articles were included for the purpose of this review. The com.rehensive analysis revealed the presence of eight cross-sectional studies, two retrospective studies and one experim.ntal study. A m.nim.m.of 25 participants and a m.xim.m.of 360 participants were included. Ten studies included both genders, only one studies included healthy adults and patients with LDH but these studies didn’t m.ntion gender. Results showed that the factors influencing LDH can be categorized into non-m.difiable factors, such as gender, age, height or others. m.difiable factors included increased Bm., Dm. sm.king, alcohol, em.loym.nt status, lifestyle and health problem. or psychology. Conclusion: Fem.les with greater VASC m.y be at risk of LDH. The lum.ar extensor m.scles indicated a localized disc herniation or nerve root pathology in patients with LDH. The fear of m.vem.nt m.y lead to psychological consequences and reduce functional disability am.ng patients with LDH.
