Authors: Schifani Enrico , Grunicke David , Montechiarini Andrea , Pradera Carlos , Vila Roger , Menchetti Mattia
Published: May 2024

The number of known alien ant species throughout Europe has been steadily increasing during the last few decades and Italy has been no exception, with four new taxa reported in the last five years. Here, we document new data on the Asian needle antBrachyponera chinensis(Emery, 1895), an invasive alien species whose first establishment in Europe was detected in the southern Italian city of Naples in 2022 and which has now been found near Lake Como in northern Italy, representing the second European record, about 730 km distant from the first. Furthermore, we report for the first time the presence ofNylanderia vividula(Nylander, 1846) in the country, based on specimens collected both in Rome and near Lake Como. This is at least the secondNylanderiaspecies established in the country afterN. jaegerskioeldi, first reported in 2018. UnlikeB. chinensis,N. vividulais not considered an ecological and health threat in the invaded range and is already known to occur in several other European countries. While only a few introduced ants in Europe are considered serious ecological, economic or health threats, the increasing circulation of several alien species and the poor ability to swiftly track their movements and detect their establishment can render management very difficult.

Authors: Kumar B. Jeevan , Thangavel Mahalingam Vijayakumar , Kumar M Ganesh
Published: May 2024

Background: Among depressed patients, escitalopram plasma levels differed between those who were considered as extensive metabolizers and poor metabolizers of CYP2C19. However, the majority of research utilized the dose-response relationship. Consequently, we investigated the effect of variations in the CYP2C19 gene on the levels of drug in the bloodstream of individuals suffering from Major Depressive Disorder (MDD) in south India.

Methods: A total of 109 individuals with MDD who were prescribed escitalopram at doses of 5, 10, 15, or 20 mg daily participated in this research. We used HPLC with SPD-10AVP UV-Visible detector to measure the escitalopram concentrations in the blood. The polymorphisms of the CYP2C19 were determined by employing the PCR techniques.

Results: Our study found that 55% of the subjects were intermediate metabolizers, followed by extensive (19.3%), poor (17.4%), and ultra-rapid (8.3%). The significant correlation is identified between the steady state plasma concentration and Sex with (P - Value < 0.05), insignificant correlation was seen in Age and BMI with (P - Value > 0.05). The majority of gene variants seen in the study population were CYP2C19*1/*2, accounting for 49 individuals (44.9%).

Conclusion: These findings showed that sex had a substantial impact on the CYP2C19 genetic variation. Medication administration to individuals with CYP2C19PM requires special caution.
Associative memories based on delayed fractional-order neural networks and application to explaining-lesson skills assessment of normal students: from the perspective of multiple $ \mathit O(t^{-\alpha}) $ stability
Authors: Ke Jiang-Wei , Zhang Jin-E
Published: May 2024

This paper discusses associative memories based on time-varying delayed fractional-order neural networks (DFNNs) with a type of piecewise nonlinear activation function from the perspective of multiple $ \mathit O(t^{-\alpha}) $ stability. Some sufficient conditions are gained to assure the existence of $ 5^n $ equilibria for $ n $-neuron DFNNs with the proposed piecewise nonlinear activation functions. Additionally, the criteria ensure the existence of at least $ 3^n $ equilibria that are locally multiple $ \mathit O(t^{-\alpha}) $ stable. Furthermore, we apply these results to a more generic situation, revealing that DFNNs can attain $ (2k+1)^n $ equilibria, and among them, $ (k+1)^n $ equilibria are locally $ \mathit O(t^{-\alpha}) $ stable. Here, the parameter $ k $ is highly dependent on the sinusoidal function frequency in the expanded activation functions. Such DFNNs are well-suited to synthesize high-capacity associative memories; the design process is given via singular value decomposition. Ultimately, four illustrative examples, including applying neurodynamic associative memory to the explaining-lesson skills assessment of normal students, are supplied to validate the efficacy of the results.

Published: May 2024

This paper describes a comparative performance analysis of sliding mode and fuzzy sliding mode controllers for climate control application of a greenhouse flower garden. Various internal and external climate related factors affect the overall growth and health of flowers that needs robust controllers to control the humidity and temperature of the greenhouse flower garden. Review of related works show that for non-linear systems, sliding mode controllers can provide robust performance even though chattering is a major drawback of the controller. A number of approaches are used to solve the chattering problem of sliding mode controllers such as hybrid uses of other controllers along with sliding mode controller. In this paper, sliding mode controller and fuzzy sliding mode controllers are designed and implemented for the specified control application based on the linearized and decoupled model of the system. The performance evaluation has been done for the control problems of reference tracking and disturbance rejection with time domain performance measures of percentage overshoot, settling time and rise time. Accordingly, the overall system has been implemented in MATLAB/Simulink and the simulations for the control problems have been done. Thus, FSMC has got rise time of 5.89min, 10.59min settling time and almost negligible percentage overshoot for indoor temperature at 27°C and humidity at 22g/m3. And for humidity control, the FSMC has got 5.44min settling time and nearly zero percentage overshoot for set point tracking problem. For the disturbance of solar radiation, decrease in outside temperature and fixed set point of 27°C and humidity of 22g/m3, FSMC outperforms SMC. In summary, both quantitative and qualitative results analysis results reveal that fuzzy sliding mode controller (FSMC) outperforms sliding mode controller (SMC) for the indoor temperature and humidity control tasks of both set point tracking and disturbance rejection problems.
Numerical Investigation of Seismic Behaviour for a Flexible Cantilever Retaining Wall with Cohesive Backfill
Authors: El Yamouni Bouraida , El Khannoussi Fadoua , Khamlichi Abdellatif
Published: May 2024

In the seismic design of flexible cantilever walls retaining cohesive backfill soil, the common practice is to neglect the cohesion effect. Dynamic lateral earth pressure is typically evaluated based on approaches primarily intended for cohesionless soils or through analytical pseudo-static methods. Nevertheless, both experimental and theoretical evidence has demonstrated significant effects due to soil cohesion that are not accounted for by these methods. This study involved finite element modeling (FE) of a flexible cantilever wall with a height of 5.4m, supporting homogeneous cohesive backfill under initial static and seismic loadings. The calculated active earth thrust was then compared with values obtained experimentally and through conventional analytical methods. The obtained results indicate that the presence of soil cohesion significantly reduces seismic demands on flexible cantilever retaining walls, resulting in a substantial reduction of seismic active earth pressures and total seismic thrust by up to 50% and 52%, respectively. It enhances also the overall stability of the system by shifting the point of application of seismic thrust toward the base of the wall, thereby increasing the safety margin. In addition, it significantly decreases the wall displacement at the stem top, with reductions of up to 104% compared with the case involving cohesionless backfill. It was observed that the conventional methods recommended by some seismic regulations largely underestimate seismic active pressure.

Authors: Singh Simar Rajan , Pandav Surinder Singh , Kaushik Sushmita , Nada Ritambhra , Gautam Natasha , Kaur Savleen , Thattaruthody Faisal
Published: May 2024

Purpose:

To study the morphological and histological characteristics of the fibrous capsule formed around a novel biodegradable glaucoma drainage device (GDD) implant made of oxidized regenerated cellulose (ORC) after 1 and 3 months of its implantation.

Methods:

It was a prospective, interventional, preclinical experimental study using New Zealand white rabbits. All animals underwent GDD implantation with a novel biodegradable device. The device’s body was made of ORC and attached to a silicone tube, connecting the body to the anterior chamber. Histopathology (hematoxylin and eosin/Masson’s trichrome staining) and immunohistochemistry (Alpha-Smooth Muscle Actin expression) characteristics of the bleb formed around the novel device were noted at 1 and 3 months.

Results:

One month post implantation, the biodegradable material produced a significant foreign body type of reaction evidenced by the exuberant infiltration by macrophages, lymphocytes, and multinucleated giant cells. The granulomatous response subsided by 3 months with disorganized collagen deposition on Masson’s trichrome staining. The silicone tube was an internal control, and histopathology demonstrated well-organized collagen deposition around it at 3 months. Immunohistochemistry for α-smooth muscle actin also demonstrated more myofibroblast transformation at the site of the tube than the biodegradable implant.

Conclusions:

Our results indicate that the tissue response around a biodegradable GDD was different from the response to conventional devices. A diffuse, loose vascularized mesh was observed to develop, which may be more compatible with sustained IOP control over a longer period, in contrast to the usual thick and dense capsule formed around the non-biodegradable devices.

Authors: Saikiran Kanamarlapudi Venkata , Gurunathan Deepa , Elicherla Sainath Reddy , Mallineni Sreekanth Kumar , Nuvvula Sivakumar
Published: May 2024

Objectives:

This study aimed to determine the mean oxygen saturation values (SpO2) in primary teeth using pulse oximetry.

Materials and Methods:

This comprehensive literature search on pulse oximeter used for primary teeth in determining pulp vitality using MeSH terms in four electronic databases, including PubMed, Scopus, Cochrane Library, and OvidSP, from January 1990 to January 2022. Studies reported the sample size and the mean SpO2 values (with standard deviations) for each tooth group were included. The quality assessment of all the included studies was done using the Quality Assessment of Diagnostic Accuracy Studies-2 tool and the Newcastle-Ottawa Scale. The meta-analysis included studies reporting means and standard deviations of SpO2 values. The I
2 statistics were used to determine the degree of heterogeneity among the studies.

Results:

A total of 90 studies were identified, of which five met the eligibility criteria that were qualified for the systematic review, and among them, three were included in the meta-analysis. All five included studies were of low quality due to the high risk of bias related to the patient selection, index test, and uncertainties about outcome valuation. In the meta-analysis, the mean fixed-effect measure of oxygen saturation in the pulp of primary teeth was 88.45% (confidence interval: 83.97%–92.93%).

Conclusion:

Though most of the available studies were of poor quality, the SpO2 in the healthy pulp can be established (minimum saturation, 83.48%) in primary teeth. Reference values established might help clinicians to assess changes in pulp status.

Published: May 2024

Background and Objectives:

Helicobacter pylori is a widely prevalent infection considered a significant public health challenge. Nigeria has the highest worldwide H. pylori prevalence. It is a notable cause of gastric cancer; thus, prompt diagnosis and treatment are required for eradication. The study aimed to determine the spectrum of endoscopic findings in patients with H. pylori infection at the University of Calabar Teaching Hospital.

Materials and Methods:

This was a retrospective cross-sectional study over a 4-year period on dyspeptic patients who presented at the hospital. Diagnosis of H. pylori infection was made through non-invasive techniques and patients who tested positive for H. pylori and were further assessed with upper gastrointestinal endoscopy were included in the study. A descriptive analysis of the data obtained was carried out using SPSS version 20.

Results:

One hundred and twenty-nine patients tested positive for H. pylori infection (46%) out of the two hundred and eighty dyspeptic patients evaluated during the period under study. However, only fifty-two (52) out of 129 dyspeptic patients who tested positive for H. pylori had upper gastrointestinal endoscopy and thus met the inclusion criteria. Upper gastrointestinal endoscopy revealed predominantly gastritis 37 (71.15%). This was followed by esophagitis in two (7.7%), duodenal ulcer two (3.8%), gastric ulcer three (5.8%), gastro-duodenitis four (7.7%), and gastric malignancy in two (3.8%) patients.

Conclusion:

Our study revealed that gastritis was the predominant endoscopic finding in patients with H. pylori infection. This finding is particularly significant because of the risk of development of gastric cancer in these patients from recurrent episodes of gastritis following late diagnosis and inappropriate treatment.

Authors: Dayar Dauda Ayuba , Raheem Yusuf Abiola , Yerima Abubakar , Mohammed Lawan , Zarami Abba B
Published: May 2024

Background:

Metastatic ovarian diseases are often found on the peritoneal surfaces including the liver, bowel, bladder, and uterus. Recent studies showed liver metastases as the most common presentation of stage-IV disease in patients with epithelial ovarian cancer (EOC). Paraneoplastic syndromes in ovarian cancers may be associated with rheumatologic disorders like polymyositis due to autoimmune mechanisms.

Case Presentation:

We report a case of a 61-year-old postmenopausal woman who presented with a 2-month history of progressive right hypochondrial swelling and pain, with progressive weight loss and weakness of the limbs. Examination revealed tender hepatomegaly with proximal muscle weakness. Abdominopelvic computed tomography (CT) scan revealed enlarged liver with multiple cystic lesions and right adnexal mass. CA125 and creatine kinase were elevated and ultrasound scan (USS)-guided trucut biopsy of both the hepatic and adnexal masses revealed papillary cystadenocarcinoma.

Conclusion:

We, therefore, concluded that the diagnosis in our patient is metastatic ovarian cancer to the liver with paraneoplastic phenomenon of polymyositis.

The rising prevalence of drug-resistant Mycobacterium tuberculosis (MTB) strains poses a significant challenge to global tuberculosis (TB) control efforts. This study aimed to analyze drug resistance patterns and investigate the molecular characteristics of 193 MTB clinical isolates to shed light on the mechanisms of drug resistance. Of the 193 MTB clinical isolates, 28.5% (n = 53) exhibited mono-drug or multidrug resistance. Pyrazinamide mono-drug resistance (PZAr) was the most prevalent (17%, n = 33), followed by isoniazid mono-drug resistance (3.6%, n = 7). Rifampicin resistance was associated with mutations in the rpoB gene (D435Y, D435V, S450L, L452P). Isoniazid resistance mutations were found in the katG (S315T), inhA (C[-15] T), and ndh (R268H) genes, whereas ethambutol resistance mutations were observed in the embB gene (M306V, M306I, M306L, G406S, Q497R). Surprisingly, 94% of PZAr isolates (n = 31) showed no mutations in the pncA or rpsA genes. The presence of the R268H mutation in the ndh gene, not previously linked to PZAr, was detected in 15% of PZAr isolates (n = 5), suggesting its potential contribution to PZAr in specific cases but not as a predominant mechanism. The specific molecular mechanisms underlying PZAr in the majority of the isolates remain unknown, emphasizing the need for further research to uncover the contributing factors. These findings contribute to the understanding of drug resistance patterns and can guide future efforts in TB control and management.
ATHLETES’ SATISFACTION TOWARDS SPORT TRAINING: AN INITIAL INVESTIGATION AND DEVELOPMENT OF QUESTIONNAIRE
Authors: Prabowo Trisnar Adi
Published: May 2024

This study aims to investigate and develop a questionnaire to measure athletes’ satisfaction towards sports training. This quantitative research used a structural equating modeling (SEM) approach with the help of Smart-PLS. The population of this study consisted of athletes from Yogyakarta Province, Riau Province, and South Kalimantan Province. The sample was 806 athletes from 27 sports (Table 1) who will compete at the National Sports Week (PON) 2024. PON is a multi-event tournament held every four years in Indonesia, so athletes who will compete have high experience and performance. Athletes who participated in this research were aged 22.6±8.3 years, and they had 10.3±4.7 years of training experience. Instrument preparation is done by reviewing the literature and focus group discussions (FGD) involving sports coaching lecturers and nationally licensed coaches. The results of this study are that the outer loading value is >0.7, and the discriminant validity value (Fornell-Larcker Criteria) is >0.7. Cronbach Alpha Reliability and Composite Reliability also showed > 0.7. Goodness of Fit (GoF) shows an SRMR value of 0.076<0.10 or <0.08, so the model fits the data. The predictive relevance test or Q Square is 0.9>0, so this study has a good observation value. Based on the results, the questionnaire consisted of 16 items divided into four dimensions (Appendix 1), namely the dimensions of training quality, mental and emotional health, competitive performance, and competitive experience. In conclusion, a questionnaire can measure athletes’ satisfaction towards sports training. From the results of this study, it is recommended that athletes’ sports training satisfaction variable be tested on indirect influences as mediating or intervening variables. It can also be used as a variable that strengthens or weakens (moderator). Then, it is combined with other independent and dependent variables in management, psychology, society, education, and sports. So that in the future, it can produce more comprehensive research.

Published: May 2024

В исследовании проведён анализ применения эконометрических методов для оптимизации управления человеческим капиталом. Цель исследования заключается в объединении различных эконометрических методов в поэтапный алгоритм для совершенствования системы управления человеческим капиталом. Методическую основу исследования составили метод главных компонент (PCA), кластерный анализ методом K-means и линейный дискриминантный анализ (LDA). Тестирование выбранных методов было реализовано с использованием языка программирования Python. В качестве объектов тестирования были отобраны предприятия из стран Евразийского экономического союза (ЕАЭС); совокупная выборка по отобранным предприятиям составила 200 наблюдений по 15 показателям, характеризующим человеческий капитал. Применение PCA для снижения размерности данных позволило упростить сложный набор данных, делая его более управляемым для выявления ключевых направлений вариабельности в аспектах человеческого капитала. Тестирование показало, что четыре главные компоненты объяснили около 78.7% вариативности данных. Применение K-means позволило провести группировку данных в четыре отдельных кластера, которые определяют различные группы сотрудников со специфическими характеристиками. Применение LDA помогло определить ключевые факторы, разделяющие кластеры. Тестирование показало, что первая и вторая дискриминантные компоненты эффективно разделили кластеры, объясняя значительную часть вариативности между ними (78.7% объясненной дисперсии). Результаты исследования демонстрируют значимость применения эконометрических методов в реальной практике управления человеческим капиталом, предлагая новые подходы и инструменты для повышения эффективности управленческих решений в условиях ускорения интеллектуального развития экономических систем.

Background: Inguinal hernia (IH) is a prevalent condition in children necessitating surgical repair. However, determining the optimal timing (early or delayed) of inguinal herniotomy in neonates and preterm infants remains debatable. While open herniotomy traditionally serves as the standard inguinal hernia repair (IHR) procedure, laparoscopic repair has gained traction in recent decades. Our study aims to scrutinize both the optimal timing and approach to inguinal hernia repair in neonates and preterm infants.
Methods: We conducted a literature review on surgical repair of IH in neonates and preterm infants published between 1999 and 2024.
Results: Twenty studies met the inclusion criteria for this review. All studies were retrospective, predominantly originating from Europe and the United States. Thirteen out of the 20 studies focused solely on preterm infants. Patient sample sizes ranged from 30 to 8037, totaling 14533 patients. Most studies indicate that delaying inguinal hernia repair in newborns and preterm infants does not increase the risk of incarceration or recurrence. Moreover, postponing repair until after discharge from the NICU correlates with a shorter postoperative hospital stay and notably diminishes the risk of long-term postoperative ventilator dependence, thereby mitigating potential perioperative complications. Hence, this approach seems safe for certain patients whose families can reliably access appropriate surgical care.
Conclusion: Significant disparities exist in the timing of inguinal hernia repair for newborns and preterm infants across various pediatric surgery centers. Current evidence suggests delayed inguinal hernia repair may be a viable option for selected patients. Regarding the optimal approach in this population, laparoscopy appears safe and effective.

Published: May 2024

The current world faces several challenges, including climate change, an exponentially increasing population, the loss of biodiversity and environmental concerns which necessities the adoption of the sustainable nature-based solutions such as agroforestry. Agroforestry is the intricate integration of trees, crops, and livestock on the same piece of land management unit that helps to restore the ecosystem, improve soil health, thus combating the environmental degradation. Moreover, agroforestry has also emerged as a potential tool that bridges the ecological preservation, while increasing or at least maintaining the productivity of the whole agroecosystem. Agroforestry is a contemporary food system that relies primarily on natural inputs, leading to the creation of more sustainable and resilient landscapes. Simultaneously, agroforestry systems reduce the soil erosion, and increases the accumulation of organic matter, hence established a closed nutrient cycling which sustain the agricultural production for longer duration. Simultaneously, agroforestry systems are effective in enhancing food security, diversifying farm income and strengthening the resilience of community to climate change thus empower the farmers and provide an opportunity to combat poverty. However, there are numerous constraints including clear land tenure rights, market infrastructure and linkage, and lack of the traditional knowledge which influenced the adoption of agroforestry systems at global level. This immediately need to be addressed by implementing flexible legislation (such as National Agroforestry Policy 2014 adopted by India), capacity building and community involvement, value chain development and payment for ecosystem services. Overall, it is crucial to adopt low-carbon perennial agroecological practices like agroforestry in order to increase the CO2 abatement rate, improve the food, nutritional and livelihood security of smallholder farmers and contribute to a more environmental friendly and sustainable future.

Mapping of Atmospheric Corrosion of Steel in Southeast India Using Inverse Distance Interpolation Technique
Authors: Ronald Joseph J. Daniel , Ashok M.
Published: May 2024

Reinforced concrete and steel structural elements undergo premature degradation and lose strength primarily due to corrosion. Corrosion is an electrochemical phenomenon and its severity depends on several environmental factors. Experimental data on the corrosion of steel is important for making engineering decisions toward improving the service life of civil infrastructures. No recent dataset on atmospheric steel corrosion in an Indian coastal environment is found to be available in the literature, and hence this research attempts to address some of the literature gap. This paper presents an experimental study conducted to determine the corrosion rate of TMT, high-chromium steel, and stainless steel rebars exposed in actual coastal and inland regions for a period of 1 y. The site locations were located in southeastern parts of Tamil Nadu state in India. Based on the first-year corrosion rate, the corrosion rate after extended exposure (10 y) was determined based on ISO 9224 recommendations. The atmospheric steel corrosion map of Tamil Nadu state was developed using inverse distance interpolation technique. Microstructural studies indicated the formation of lepidocrocite (γ-FeOOH) phase composition in the rust products collected from coastal regions.
Cultural Intelligence and Sustainable Career Success in Intercultural Service Encounters
Authors: Tungtakanpoung May , Prouska Rea
Published: May 2024

Scholars have explored individual, organisation and external factors impacting career sustainability and framed these as part of a career ecosystem. While productivity is considered pivotal for career sustainability according to conceptual frameworks, there remains a gap in understanding
its practical implications for occupations involving Intercultural Service Encounters (ICSEs). Culture significantly influences the attitudes and behaviours of service employees and shapes customers’ perceptions of service quality, thereby making cultural intelligence (CQ) a key competency
for employees working in ICSEs settings such as in cultural tourism and the airline industry. This paper adopts De Vos, Van der Heijden, and Akkermans (2020) conceptual framework to underscore the significance of CQ in ICSEs and its connection to performance, thus fostering career sustainability
in such contexts. Data from an ethnographic case study in Thai Airways, comprising semi-structured interviews with cabin crew employees, observations, and company records, were collected. Our study highlights the significance of CQ competencies in expanding the understanding of sustainable
careers in ICSEs settings and aligns with the Career Ecosystem theory by emphasising the interplay between individuals, organisations, and national culture in shaping sustainable careers in such settings.

Le marketing au service du développement durable
Authors: Dekhili Sihem
Published: May 2024

Nombreux sont ceux qui voient le marketing et le développement durable comme deux domaines complètement éloignés, voire opposés. Pourtant, le marketing occupe une position privilégiée pour encourager des transformations au niveau de la production et orienter les consommateurs vers des comportements responsables. Dès son origine, le marketing s’est placé comme support d’une relation entre l’entreprise et ses clients, la quête du bien-être appartenant aux fondements mêmes de la discipline. Dans un contexte marqué par des crises et par un scepticisme ambiant, le marketing devrait aujourd’hui, plus que jamais, prouver « sa bonne foi ». Cet ouvrage offre aux praticiens, pouvoirs publics, enseignants et étudiants des illustrations démontrant que disséminer les pratiques durables est bien une question de marketing. Il affirme l’intérêt tout particulier de dépasser le clivage entre les deux notions, mais également celui de s’appuyer sur les outils et cadres d’analyse du marketing pour soutenir un développement durable et renforcer le marché vert.

Abstract. TP53 has been shown to be involved in lactation in cattle. However, the role of TP53 in buffalo lactation remains unknown. To this end, we isolated and identified the complete coding sequence (CDS) of the TP53 gene from the buffalo mammary gland and further analyzed its molecular characteristics, function, tissue differential expression, and single-nucleotide polymorphism (SNP). A transcript of this gene was cloned with a CDS length of 1161 bp, encoding a protein consisting of 386 amino acid residues. Bioinformatics analysis showed that buffalo TP53 CDS and the physicochemical characteristics, conserved domains, structure, and function of its encoded protein are highly similar to those of other species in Bovidae. The buffalo TP53 protein contains an N-terminal activation domain, a DNA-binding domain, and a tetrameric domain, and it plays a functional role in the nucleus. TP53 was found to express in all 11 detected buffalo tissues, and its expression in the heart, kidney, brain, muscle, and rumen during lactation was significantly higher than that during non-lactation (p<0.05), while in the liver, lung, and mammary gland, its expression was the opposite (p<0.05). Interference experiments in buffalo mammary epithelial cells (BuMECs) showed that TP53 inhibits the expression of genes related to milk protein and milk fat synthesis through the PI3K–AKT–mTOR pathway. A synonymous nucleotide substitution (c.204C > T) was found in the TP53 CDS of river buffalo, which is the CC homozygote in swamp buffalo. The results indicate that the TP53 gene is involved in buffalo lactation by negatively regulating the synthesis of milk protein and milk fat.

Abstract. Most anthropogenic carbon dioxide (CO2) emissions originate from urban areas. To improve understandings of urban and regional emissions, we design and construct a low-cost UAV coordinated carbon observation network (LUCCN) which uses mid-accuracy (±1 ppm) CO2 sensors. In this paper, we introduce our multi-variable non-linear regression method for calibrating the non-dispersive infrared (NDIR) CO2 sensors for LUCCN’s ground stations. We tested our calibration method with concentration data collected at the Xinglong Atmospheric Background Observatory. With comparison against data simultaneously collected by a high-accuracy cavity ring-down spectrometer, we found the maximum standard deviation of LUCCN’s sensors to be 0.782 ppm in a controlled laboratory environment with a 1-second window size and 0.53 ppm in an outdoor environment with a 1-hour running average window size. As validation of LUCCN’s ground measurements, we identify and present consistent trends between local CO2 concentration variations and aerosol pollution events captured by the space-based moderate resolution imaging spectrometer (MODIS).
