Diorganotin(IV)-2-mercaptopyrimidine complexes

Field: Chemistry (Physical Sciences)

The complexes formed between the diorganotin(IV) moieties, R2Sn(IV), and the ligand 2-mercaptopyrimidine, (H)SPym, were investigated. Complexes R2SnHal(SPym) and R2Sn(SPym)2 [R = Me, iPr, nBu, iBu, tBu, cyclohexyl(Cy), Ph] were synthesized, and characterized by elemental analysis. In the solid state, chelation of SPym through S and N donors was established by IR spectroscopy, and the nature of the environment of tin centers was investigated by 119Sn Mössbauer spectroscopy. From the dynamics of 119Sn nuclei determined by variable-temperature measurements on representative compounds [Me2SnCl(SPym) and Cy2SnBr(SPym)], as well as by point-charge model treatment of nuclear quadrupole splitting parameters, it was inferred that Me2SnCl-­(SPym) may assume a trans-Me2 octahedral coordination geometry around tin in a monodimensional polymer, or a monomeric trigonal-bipyramidal structure (distorted). The latter type of structure was assigned to the other R2SnHal(SPym) species, while R2Sn(SPym)2 complexes assume a trans-octahedral, or skew trapezoidal, tin environment. In CHCl3–CDCl3 solutions, monomeric species occur (according to vapor-pressure osmometry), where 1H and 13C NMR spectroscopic parameters of SPym indicate the persistence of Sn chelation by S and N donor atoms. The Me2SnCl(SPym) species assume trigonal-bipyramidal structures with a chelating SPym ligand, in CDCl3 and C2H5OH solutions, according to the coupling constants 1J(119Sn,13C), as well as IR and 119Sn Mössbauer spectroscopic data. 119Sn NMR parameters fully correspond with data for the homologous complexes with 2-mercaptopyridine.

Cross-boundary software engineering: Implications of engineering paradigm shift

Field: Computer Science (Physical Sciences)

Software engineering is a rigid process for dealing with machine-readable information using imprecise human hands. This legacy monolithic software engineering needs to address the emerging challenges involving heavy engagement of human communications. The author describes cases of this new trend and advantages of communication-centered software engineering. Then, the author proposes a cross-boundary software engineering model in order to describe these cases. The author discusses transition patterns for coping with these challenges. Using this model, the author describes issues for enterprises and for academic education.
204 Piglets exhibited similar performance when fed OH-methionine or DL-Methionine during the post-weaning period

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract This work aimed to compare piglet’s performance when fed DL-Methionine or Hydroxy-Methionine (OH-Met and OH-MetCa) at the requirements of sulfur amino acids (SAA) or above. 720 piglets (♀ large white*landrace x ♂ pietrain*duroc) were weaned at 28 days old (6.84 ± 1.07 kg) and randomly allocated to the experimental treatments for 42 days. The experiment was a factorial design with three Met sources (DL-Met, liquid OH-Met (acid form) or OH-MetCa under powder form) and two doses of SAA. Treatments were formulated to reach the adequate SID SAA/Lys ratio of 58% or exceeded the Spanish nutrient recommendations in SAA by 25% (0.79% SID SAA/Lys). Each treatment was replicated 12 times (6 pens of males and 6 pens of females). Growth performance was measured and data was analysed by mixed-effects models (R Core Team). The body weight was neither affected by SAA level, nor by the Met sources. The daily weight gain (DWG) was not affected by the dietary treatments from 0 to 21 days; whereas the feed conversion ratio (FCR) was significantly (P=0.01) improved when the SAA level was increased by 25% (1.272 and 1.184) due to the decreased feed intake (P=0.03). Significant interactions were found between the Sex and the SAA level for DWG (P = 0.04) and FCR (P = 0.03) from 0 to 21 days. From day 21 to 42 and from day 0 to 42, no performance criteria were different in all dietary treatments. For all criteria of performance, the three Met sources exhibited a similar response. These results confirmed that Met sources are equivalent in piglets.

Choice of Optimal Planting and Marketing Decisions for Fresh Vegetable Producers: A Mathematical Programming Approach

Field: Agricultural and Biological Sciences (Life Sciences)

This study combines whole farm economic analysis with biophysical simulation techniques in order to achieve a twofold objective. First, the study seeks to develop a multiple enterprise vegetable farm model with a production and marketing decision interface and, second, to determine optimal production practices for Kentucky vegetable growers. Three vegetable crops are examined: tomatoes, bell peppers and sweet corn. The findings indicate that the risk associated with vegetable production can be significantly mitigated with diversification of production mix and with a greater number of transplanting dates. However, this reduction in risk comes at a high cost in terms of expected net returns.
Application of remote sensing big data in landslide identification

Field: Earth and Planetary Sciences (Physical Sciences)

&lt;p&gt;Landslides are general natural disasters in the world. Knowledge on the landslide distribution is fundamental for landslide monitoring, disaster mitigation and reduction. Traditional in-situ observations (e.g., leveling, GPS, extensometer, inclinometer) usually have high accuracy, but they are expensive and labor intensive and may also involve risks in the field. Alternatively, remote sensing data can capture the regional land surface features and thus are efficient in landslide mapping. Recent studies on landslide identification mainly rely on the pixel-based or object-oriented classification using optical images. Nonetheless, landslide activities are governed by multiple processes including the topography, geology, land cover, catchment, precipitation, and tectonics (e.g., dynamic shaking or aseismic creeping). Remote sensing data and products are beneficial to extract some of these critical parameters on a regional scale. Rapid development of machine learning algorithms makes it possible to systematically construct landslide inventory by interpreting multi-source remote sensing big data. The populous California suffers from high risks of landsliding. The United States Geological Survey (USGS) compiles the landslide inventory in the State and reports that California has about 86k landslides. Steep slope in the costal ranges, wet climate in the northern California, youthful materials at the surface from active tectonics of the San Andreas Fault and secondary fault systems, dynamic and aseismic movements instigated from the faults all contribute to high landslide susceptibility in California. In May 2017, the steep slopes at Mud Creek on California&amp;#8217;s Big Sur coast collapsed catastrophically. During January and February in 2019, several landslides occurred on the southern part of Santa Monica Mountains. In January 2021, a large debris flow hit the Rat Creek in Big Sur due to extreme precipitation. In addition, a fairly complete collection of remote sensing data and products are available in California. Here we use machine learning methods to refine landslides in California using remote sensing big data, including elevation, slope, and aspect derived from SRTM digital elevation models (DEM), the normalized differential vegetation index (NDVI) derived from Landsat 8 OLI images, the hydrometeorological observations, the nearest distance to rivers and faults, the geological and land cover maps, as well as Synthetic Aperture Radar (SAR) images. We will use the archived landslide inventory for model training and testing. We plan to further explore the critical variables in determining landslide occurrences and the inferred triggering mechanisms.&lt;/p&gt;
On integrability of a new dynamical system associated with the BBM‐type hydrodynamic flow

Field: Mathematics (Physical Sciences)

This article explores the exceptional integrability property of a family of higher‐order Benjamin –Bona–Mahony (BBM)‐type nonlinear dispersive equations. Here, we highlight its deep relationship with a generalized infinite hierarchy of the integrable R iemann ‐type hydrodynamic equations. A previous L ie symmetry analysis revealed a particular case which was conjectured to be integrable. Namely, a Lie –Bäcklund symmetry exists, thus highlighting another associated dynamical system. Here, we investigate these two equations using the gradient‐holonomic integrability scheme. Moreover, we construct their infinite hierarchy of conservation laws analytically, using three compatible P oisson structures to prove the complete integrability of both dynamical systems. We investigate these two equations using the so‐called gradient‐holonomic integrability scheme. Based on this scheme, applied to the equation under consideration, we have analytically constructed its infinite hierarchy of conservation laws, derived two compatible P oisson structures, and proved its complete integrability.
Comparison of the Treatment Efficacy of Rituximab and Plasmapheresis/Intravenous Immunoglobulin Combination with Historical Control in Chronic Antibody Mediated Rejection

Field: Medicine (Health Sciences)

OBJECTIVE: Chronic antibody mediated rejection (CAMR) is a major therapeutic challenge for achieving long-term graft survival; treatment options are limited to several anti-humoral interventions. MATERIAL and METHODS: Efficacy of rituximab combination therapy was retrospectively investigated by comparison with a historical control group for allograft function at six month and overall graft survival/dysfunction. The inclusion criterion was biopsy proven chronic AMR according to the Banff 2007 classification. Nineteen patients found eligible, rituximab group had nine patients (rituximab, plasmapheresis and low dose IVIG); control group had ten recipients. Predictive factors for graft failure also investigated according to Banff scores and renal functions. RESULTS: None of the outcomes were exposed significant efficacy of rituximab, although better treatment response at sixth month (55% vs. 40%, p= 0.51), fewer overall graft failures (33% vs. 60%, p= 0.25) and dysfunctions (66% vs. 80%, p= 0.52). Overall, 47% of patients suffered graft failure. Advanced transplant glomerulopathy was found in 90% of biopsies (all scored = 2). Peritubular capillaritis score (1.67 +/- 0.87 vs. 0.70 +/- 0.94, p= 0.04) and interstitial inflammation score (1.78 +/- 0.44 vs. 1.00 +/- 0.47, p= 0.004) were significantly higher in recipients who suffered graft failure. CONCLUSION: Rituximab could not sufficiently prevent further deterioration of allograft and failed to improve allograft survival in CAMR, especially after settlement of the irreversible transplant glomerulopathy.
Endothelin-1 Induced Phosphorylation of Caveolin-1 and Smad2C in Human Vascular Smooth Muscle Cells: Role of NADPH Oxidases, c-Abl, and Caveolae Integrity in TGF-β Receptor Transactivation.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Caveolin-1(Cav-1) is one of the most important components of caveolae in the cell membrane, which plays an important role in cell signaling transduction, such as EGFR and TGF-β receptor transactivation. The purpose of this study was to evaluate the effect of c-Abl and NAD(P)H oxidases (NOX) on phosphorylation of Cav-1 and consequently their effect on phosphorylation of Smad2C induced by Endothelin-1 in human vascular smooth muscle cells (VSMCs). In this study, all experiments were performed using human VSMCs. The phosphorylation level of the Caveolin-1 and Smad2C proteins were assessed by western blotting using Phospho-Caveolin-1 (Tyr14) antibody and phospho-Smad2 (Ser465/467) antibody. The data were reported as mean ± SEM. The VSMCs treated with endothelin-1(ET-1) (100 nanomolar (nmol)) demonstrated a time-dependent increase in the pCav-1 level (p<0.05). The inhibitors of NOX (diphenyleneiodonium) (p<0.05), cholesterol depleting agent (beta-cyclodextrin) (p<0.05) and c-Abl inhibitor (PP1) (p<0.01) were able to reduce the level of the phospho-Cav-1 and phospho-Smad2C induced by Et-1 (p<0.05). Our results proposed that caveolae structure, NOX, c-Abl played an important role in the phosphorylation of Cav-1 induced by ET-1 in the human VSMCs. Furthermore, our findings showed that phosphoCav-1 involved in TGFR transactivation. Thus, Et-1 via a transactivation-dependent mechanism can cause phosphorylation of Smad2C.
Les nuits de Strasbourg: Creolization at the Crossroads of Europe

Field: Arts and Humanities (Social Sciences)

Assia Djebar’s 1997 novel, Les nuits de Strasbourg, has often been read narrowly as “cosmopolitan” or as a commentary on war and memory. I explore this complex text through a new lens—creolization—a concept only recently emerging from the regional limitations historically imposed on its use. Blurring national, linguistic, religious, and ethnic boundaries, Djebar questions assumptions about post-colonial creolized identities. Formed and informed by overlapping memories (personal/collective, official/unofficial), as well as by orality, plural identities, and multilingualism, this novel illustrates the process and promise of creolization.
Tax : efficient supply chain management

Field: Business, Management and Accounting (Social Sciences)

Supply chain management is a becoming increasingly important in today’s globalized markets. For manufacturing industry, the performance of industrial players is no longer determined solely by the characteristics of their products but lies on the effectiveness of the whole supply chain management. The measurement of supply chain efficiency can be based on several different metrics. In most cases, managing the trade-offs between costs and customer service level is the most common measure. Despite recent studies on the topic of tax efficient supply chain management, rarely is indirect tax a focus; yet there are huge potential to significantly improve the companies’ supply chain efficiency by combing indirect tax and supply chain management, especially the distribution network design given the nature of indirect tax. This paper aims to analyse the impact of indirect tax in the context of various distribution networks, to identify and prioritize trade-offs basis the existing supply chain management models from a manufacturing supply chain perspective.

Utilization of online crowdfunding for alternative cancer treatments at home and abroad.

Field: Medicine (Health Sciences)

e14044 Background: The use of alternative cancer treatments has been associated with decreased survival. However, little is known about the types of individuals who seek out these therapies, the alternative therapies pursued, and the associated costs. We utilized GoFundMe campaigns to characterize the types of patients who sought alternative cancer treatments, the types of therapies pursued, and the associated costs. Methods: We queried GoFundMe ( www.gofundme.com ) for English language campaigns using the term “alternative cancer treatment” using custom code for web scraping on 10/25/2019. We identified 1000 campaigns between 2011-2019, of which, 795 had received donations and were used for analysis. We studied each individual campaign in detail and extracted relevant information. Results: The majority of patients were female (63.5%). The most common cancer types were breast (25.3%), colorectal (10.8%), and lung (5.5%) cancer. Of patients reporting cancer stage, 79.3% had stage IV disease. Of those reporting prior cancer treatment history, 34.8% had never undergone traditional cancer treatment; 42.1%, 46.8%, and 26.6% had undergone prior surgery, chemotherapy, and radiotherapy, respectively. The most common proposed alternative treatments were vitamins and minerals (23.4%), herbs and botanicals (16.1%), special diets (13.0%), supplements (10.8%), heat or light therapy (7.8%), IV infusions (7.8%), homeopathic/naturopathic therapies (7.2%), and hyperbaric oxygen therapy (5.9%). Among all campaigns, a total of $36,394,110 was requested and a total of $8,601,759 (23.9%) was raised. The median campaign fundraising goal was $25900 (US dollars; Interquartile range [IQR] $1000 – $50000); the median amount donated was $5805 (IQR $2595 – $12580). These costs include travel as 629 (79.1%) campaigns were for patients residing in the USA, 70 (8.8%) in Europe, 62 (7.8%) in Canada, and 34 (4.3%) in other regions, from which, 54.3% of patients stated that they planned to travel internationally—most commonly to Mexico—for their alternative cancer treatments. Conclusions: Millions of dollars have been requested and raised between 2011 and 2019 for alternative cancer treatments. The majority of patients sought treatment at alternative clinics internationally, were females, had stage IV disease and primary tumors of the breast, colon/rectum or lung, who had previously undergone traditional cancer therapies, and highlight a group of patients where improved communication/education between providers and patients appears to be needed.
O tempo como medi[a]dor estético: criação e receção da obra

Field: Arts and Humanities (Social Sciences)

Time presides, directs the existence of the work, in the person of the subject-author, even when it is not evident in a first aesthetic reception. In contemporary art, despite the diversity of languages that assist it and the wear and tear (and controversy) that the concept carries, time takes hold and settles down. The manifested artistic assumptions, the meanings that define it, correspond to the role, relevance and context in which the author intends it. Time is simultaneously cause and effect, weighted through ideas and materialities, devices and evanescences that make it possible to see, hear, enjoy. Some works by artists are analyzed that: 1. Develop their production under the rationalizing / sense-perceptive aegis of the idea of time; 2. Establish (or not) the idea as a hinge, name and / or even intend to identify it. 3. They seek to apprehend, differentiate and underline the ways in which, as a receiver / subject, it points out or intuitively, in aesthetic terms. Still, to what extent, what is the dimension and modalities, in time is it treated (or is it substance): slowness, stillness, duration, delay, instant, ephemerality, fleeting precariousness; how it is transferable, interchangeable, perceptible and how it interferes and extrapolates beyond the perimeter of viso-verbal perception.
