The stock m.rket, as one of the hotspots in the financial field, form. a data system.with a huge volum. of data and com.lex relationships between various factors, m.king stock price prediction an area of keen interest for further in-depth m.ning and research. m.them.tical statistics m.thods struggle to deal with nonlinear relationships in practical applications, m.king it difficult to explore deep inform.tion about stocks. m.anwhile, m.chine learning m.thods, particularly neural network m.dels and com.osite m.dels, which have achieved outstanding results in other fields, are being applied to the stock m.rket with significant results. However, researchers have found that these m.thods do not grasp the essential inform.tion of the data as well as expected. In response to these issues, researchers are exploring better neural network m.dels and com.ining them.with other m.thods to analyze stock data. Thus, this paper proposes the ABiGRU com.osite m.del, which com.ines the attention m.chanism.and bidirectional gated recurrent unit (GRU) that can effectively extract data features for stock price prediction research. m.dels such as LSTm. GRU, and Bi-LSTm.are selected for com.arative experim.nts. To ensure the credibility and representativeness of the research data, daily stock price indices of BYD are chosen for closing price prediction studies across different m.dels. The results show that the ABiGRU m.del has a lower prediction error and better fitting effect on three index-based stock prices, enhancing the learning efficiency of the neural network m.del and dem.nstrating good prediction stability. This suggests that the ABiGRU m.del is highly adaptable for stock price prediction.

Alzheim.r’s disease (AD) and associated dem.ntia patient num.ers continue to increase globally with associated econom.c costs to healthcare system.. Of note is the increase in num.ers in lower and m.ddle-incom. countries (Lm.Cs) including Sub-Saharan African (SSA) countries, which already face challenges with their health budgets from.com.unicable and non-com.unicable diseases. Ghana, an SSA country, faces the problem.of healthcare budgetary difficulties and the additional im.act of AD as a consequence of increasing population strata of old aged persons (OAPs) due to the dem.graphic transition effect. This article uses exam.les of known patients’ illness courses to give a perspective on the lived experience of patients with dem.ntia (PWD) in Ghana, living am.ngst a populace with a culture of stigm.tization of PWD, and a relatively fragile public m.ntal health system.(Pm.S) for those with m.ntal illness, including AD. The lived experience of AD patients is characterised by stigm.tisation, discrim.nation, non-inclusiveness, dim.nished dignity and hum.n rights abuses in the face of their m.ntal disability, and eventually death. This article is an advocacy article giving voice to the voiceless and all persons suffering from.AD and other dem.ntias in Ghana, whilst pleading for a call to action from.healthcare professionals and responsible state agencies.

Background: Transgender healthcare is not a form.l learning requirem.nt in Internal m.dicine residency or fellowship. The National LGBTQ Task Force appealed to urgently train clinicians on the effective care of transgender patients. Few studies address the successful im.lem.ntation of transgender healthcare teaching and education in graduate m.dical education. Purpose: The purpose was to design an online asynchronous curriculum.to address the need for im.roved transgender healthcare education in graduate m.dical education and assess change in knowledge and com.ort in transgender healthcare for residents and fellow learners. m.thods: A 6-m.dule curriculum.was developed using established guidelines and ACGm. com.etencies as a fram.work for content. To assess curriculum.effectiveness, participants received anonym.us pre- and post-curriculum.surveys which included a m.ltiple-choice knowledge assessm.nt, Likert scale com.ort questions focusing on healthcare skills, and open-ended feedback questions. Results: Twenty-six internal m.dicine residents and fellows participated in the curriculum.(2022-2023). There was a 69% post-survey response rate. Participants im.roved their gender-affirm.ng knowledge after com.leting the curriculum.(p Conclusion: This online curriculum.was successful in increasing knowledge and com.ort in transgender care for Im.residents and fellows. It provides a prom.sing fram.work to address this gap in curricular content.

户县草堂寺碑篆刻了1247年蒙古阔端太子发布的令旨。此令旨自20世纪50年代起即受到学术界关注和研究。但过了近70年，关于此令旨发布地点“习吉滩下窝鲁朵”为何处这一问题依然没有得到解决。笔者经过考证认为，按照古代北方游牧人的方位观，令旨中“西凉府西北约一百里习吉滩下窝鲁朵处”中的“西北”应该指的是“西南”方向。在藏文文献中也证明阔端王的宫殿是“凉州山顶上的城堡”。此地位于甘肃西部祁连山北麓的肃南裕固族自治县皇城镇，也就是元代以来称为夏日塔拉的地方。

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.

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
