A Protocol for the Multi-Omic Integration of Cervical Microbiota and Urine Metabolomics to Understand Human Papillomavirus (HPV)-Driven Dysbiosis
Authors: Chorna Nataliya , Godoy-Vitorino Filipa
Published: April 2020

The multi-omic integration of microbiota data with metabolomics has gained popularity. This protocol is based on a human multi-omics study, integrating cervicovaginal microbiota, HPV status and neoplasia, with urinary metabolites. Indeed, to understand the biology of the infections and to develop adequate interventions for cervical cancer prevention, studies are needed to characterize in detail the cervical microbiota and understand the systemic metabolome. This article is a detailed protocol for the multi-omic integration of cervical microbiota and urine metabolome to shed light on the systemic effects of cervical dysbioses associated with Human Papillomavirus (HPV) infections. This methods article suggests detailed sample collection and laboratory processes of metabolomics, DNA extraction for microbiota, HPV typing, and the bioinformatic analyses of the data, both to characterize the metabolome, the microbiota, and joint multi-omic analyses, useful for the development of new point-of-care diagnostic tests based on these approaches.
Spatiotemporal Dynamics of Multiple Memory Systems During Category Learning
Authors: K. Morgan Kyle , Zeithamova Dagmar , Luu Phan , Tucker Don
Published: April 2020

The brain utilizes distinct neural mechanisms that ease the transition through different stages of learning. Furthermore, evidence from category learning has shown that dissociable memory systems are engaged, depending on the structure of a task. This can even hold true for tasks that are very similar to each other, which complicates the process of classifying brain activity as relating to changes that are associated with learning or reflecting the engagement of a memory system suited for the task. The primary goals of these studies were to characterize the mechanisms that are associated with category learning and understand the extent to which different memory systems are recruited within a single task. Two studies providing spatial and temporal distinctions between learning-related changes in the brain and category-dependent memory systems are presented. The results from these experiments support the notion that exemplar memorization, rule-based, and perceptual similarity-based categorization are flexibly recruited in order to optimize performance during a single task. We conclude that these three methods, along with the memory systems they rely on, aid in the development of expertise, but their engagement might depend on the level of familiarity with a category.
Cognitive Learning about Waste Management: How Relevance and Interest Influence Long-Term Knowledge
Authors: Stöckert Alexandra , Bogner Franz X.
Published: April 2020

Efficient waste management is a major prerequisite for reaching sustainability as every one of us produces waste. Thus, educational interventions need to offer promising assistance to reduce individual waste as much as possible to promote environmentally friendly behavior beyond stereotypical notions about waste disposal. Those who know about all facts and circumstances are more likely to correct their behavior. Our hands-on module for fifth graders was designed and implemented to support “4R”: Reduce, Reuse, Recycle and Recover, by retracing waste’s usual journey from collection management to incineration plants. The first module focused on minimizing waste by recycling, reusing and reducing it. The remaining waste was the second module’s core, which explained the waste-to-energy path using an age-appropriate functional model of how to effectively generate energy from waste. Both modules are suitable for outreach (informal) implementation as well as for formal classroom learning. The third module comprised either an onsite visit to an incineration plant or a classroom multimedia presentation. A total of 276 fifth graders participated in our three-module implementation study, completing three questionnaire cycles: two weeks before the intervention, immediately after and six weeks later. A subsequent analysis showed a clear pattern: knowledge scores increased immediately after participation and remained constant for at least six weeks. Surprisingly, no significant difference between the multimedia and outreach group appeared. When applying a semantic differential, two response pattern factors, “Relevance” and “Interest”, showed significant intercorrelations, as well as positive correlations with knowledge scores. In consequence, learning about waste management matters, and produces short- and long-term effects.

Authors: Paradiso Vito Michele , Castellino Maria , Renna Massimiliano , Santamaria Pietro , Caponio Francesco
Published: April 2020

Microgreens are gaining increasing interest as a potential functional food due to their relevant contents of micronutrients and bioactive compounds, including carotenoids. Nevertheless, the analysis of carotenoids is inherently difficult, due to their thermal and chemical susceptibility, as well as to their varying polarity. From this point of view, extraction is the most critical step, compared to chromatographic separation and detection. Thus, the reliability of data on carotenoids should be guaranteed by a constant focus on analytical issues, with appropriate adaptations to each sample matrix. In this research, a specific extraction procedure for the analysis of carotenoids in microgreens was developed. Solvent composition, extraction time, solvent/sample ratio, and repeated extractions were evaluated. The obtained protocol showed recovery of 97.2%, limits of quantitation of 5.2 μg·g−1 for lutein and 15.9 μg·g−1 for β-carotene, as well as intra-day mean repeatability of 5.7% and inter-day mean repeatability of 4.7%.
Consumer Description by Check-All-That-Apply Questions (CATA) of the Sensory Profiles of Commercial and New Mandarins. Identification of Preference Patterns and Drivers of Liking
Authors: Tarancón Paula , Tárrega Amparo , Aleza Pablo , Besada Cristina
Published: April 2020

In the last few years, the interest in developing new mandarin cultivars of superior quality has grown as a response to the increasing consumer demand of this appreciated fruit. This study evaluated the sensory profiles of five new late-season mandarin cultivars (‘Alborea‘, ’Coral‘, ’Omet‘, ’Matiz‘ and ’Tri-703‘) and six commercial cultivars found contemporarily in stores (‘Clemenules‘, ’Nova‘, ’Tango‘, ’Nadorcott‘, ‘Orri’ and ‘Ortanique’). The sensory profiles of the cultivars were described by consumers through CATA questions. Consumers’ acceptability and the main physico-chemical properties were also evaluated. Twenty-two out of 23 CATA terms differed significantly for the sensory profiles of the studied cultivars. The new cultivars shared a similar profile, described mainly as “very intense taste”, “refreshing taste”, “very aromatic” and “juicy”, and these characteristics were quite different from those of the commercial cultivars. By combining acceptability and CATA questions, drivers of liking for segments of consumers with different preference patterns were identified. This is the first time that the sensory profiles of mandarin cultivars have been described by consumers. A significant number of consumers preferred the new mandarin cultivars to the commercial ones, which allows them a promising introduction on the market.
A COLREGs-Based Dynamic Navigation Safety Domain for Unmanned Surface Vehicles: A Case Study of Dolphin-I
Authors: Zhou Jian , Wang Chenxu , Zhang Anmin
Published: April 2020

Unmanned Surface Vehicles (USVs) are intelligent machines that have been widely studied in recent years. The safety of USVs’ activities is a priority issue in their applications; one effective method is to delimit an exclusive safety domain around the USV. Besides considering collision avoidance, the safety domain should satisfy the requirements of encounter situations in the COLREGs (International Regulations for Preventing Collisions at Sea) as well. Whereas the model providing the safety domain for the USVs is defined through the experience of the manned ships, a specific model for USVs has been rarely studied. A dynamic navigation safety domain (DNSD) for USVs was proposed in this paper. To construct the model, the essential factors that could affect the navigation safety of the USVs were extracted via a rough set, and the extension functions of these factors were carried out. The DNSD was employed in various situations and compared with the ship domain models of common ships. It was found that the domain boundary can be automatically corrected according to the change in the working conditions when the DNSD is in use. Compared with the Fujii and Coldwell models, the DNSD can provide a larger safety area for a USV’s action of collision avoidance.
Re-Evaluating the Classical Falling Body Problem
Authors: El-Zahar Essam R. , Ebaid Abdelhalim , Aljohani Abdulrahman F. , Tenreiro Machado José , Baleanu Dumitru
Published: April 2020

This paper re-analyzes the falling body problem in three dimensions, taking into account the effect of the Earth’s rotation (ER). Accordingly, the analytic solution of the three-dimensional model is obtained. Since the ER is quite slow, the three coupled differential equations of motion are usually approximated by neglecting all high order terms. Furthermore, the theoretical aspects describing the nature of the falling point in the rotating frame and the original inertial frame are proved. The theoretical and numerical results are illustrated and discussed.

Published: April 2020

Probiotics are increasingly being used as a nutritional supplement by athletes to improve exercise performance and reduce post-exercise fatigue. Lactobacillus salivarius is a natural flora in the gastrointestinal tract of humans and animals. Lactobacillus salivarius subspecies salicinius (SA-03) is an isolate from the 2008 Olympic women’s 48 kg weightlifting gold medalist’s gut microbiota. In this study, we investigated its beneficial effects on physical fitness. Male ICR mice were divided into four groups (n = 10 per group) and orally administered with SA-03 for 4 weeks at 0, 2.05 × 109, 4.10 × 109, or 1.03 × 1010 CFU/kg/day. Results showed that 4 weeks of SA-03 supplementation significantly improved muscle strength and endurance performance, increased hepatic and muscular glycogen storage, and decreased lactate, blood urea nitrogen (BUN), ammonia, and creatine kinase (CK) levels after exercise. These observations suggest that SA-03 could be used as a nutritional supplement to enhance exercise performance and reduce.

Published: April 2020

Since the observation of direct interspecies electron transfer (DIET) in anaerobic mixed cultures in 2010s, the topic “DIET-stimulation” has been the main route to enhance the performance of anaerobic digestion (AD) under harsh conditions, such as high organic loading rate (OLR) and the toxicants’ presence. In this review article, we tried to answer three main questions: (i) What are the merits and strategies for DIET stimulation? (ii) What are the consequences of stimulation? (iii) What is the mechanism of action behind the impact of this stimulation? Therefore, we introduced DIET history and recent relevant findings with a focus on the theoretical advantages. Then, we reviewed the most recent articles by categorizing how DIET reaction was stimulated by adding conductive material (CM) and/or applying external voltage (EV). The emphasis was made on the enhanced performance (yield and/or production rate), CM type, applied EV, and mechanism of action for each stimulation strategy. In addition, we explained DIET-caused changes in microbial community structure. Finally, future perspectives and practical limitations/chances were explored in detail. We expect this review article will provide a better understanding for DIET pathway in AD and encourage further research development in a right direction.

Published: April 2020

Sulfur compounds are removed from petroleum by the addition of sodium hydroxide at a very high concentration. As a result, a residue called spent soda or spent caustic is generated, being extremely aggressive to the environment. In this work, the chemical properties of this residue are described in detail. The sodium hydroxide remains that have not reacted, sulfur compounds, and organic matter are the primary pollutants reported. Additionally, the main characteristics of the methods of treatment used to reduce them are described. This review comes from comprehensive and updated research and bibliographic analysis about the investigation on the topic. The advantages and disadvantages of the different treatment methods are highlighted. We established some criteria to set out when assessing the application of each one of these treatments is considered.
Influence of Selected Parameters and Different Methods of Implementing Vacuum Impregnation of Apple Tissue on Its Effectiveness
Authors: Guz Tomasz , Rydzak Leszek , Domin Marek
Published: April 2020

The study provides comprehensive information on the vacuum impregnation process applied to plant materials. It aims (in traditional applications) to ensure impermeability and elimination of porosity of various materials. The process substantially accelerates mass transfer in the liquid–solid system. The study describes the course of the process and accompanying phenomena as well its effects on plant tissues. The aim of the investigations was to determine the impact of some impregnation parameters (pressure, pressure change rate, vacuum maintenance time, relaxation time, and the coefficient of impregnating liquid viscosity) and the mode of impregnation (wet, dry, cyclic wet) on the degree of filling the plant tissue with the impregnating solution. Jonagold apples were used as the study material. The investigations have revealed that changes in the vacuum impregnation parameters (vacuum maintenance time, relaxation time, pressure change rate in the system) and the impregnation method do not exert a significant impact on the effectiveness of the process as expressed by the degree of permeation of the impregnating solution into the tissue. The pressure value and the viscosity coefficient were the only parameters that had a significant effect on the impregnation yield.

Outline of Real Physics
Authors: Liang Zhong-Cheng
Published: April 2020

Real physics is an axiomatic theoretical system based on the model of elastic particles. Unlike point-like and wave-like particles, elastic particles are objects with both mass and volume, which can spin and deform. Electrons, protons, and atoms are elastic particles. Elastic particles have three motion modes of translation, rotation, and vibration. The system of elastic particles follows simple and universal laws of motion. This paper briefly reviews the core concepts, basic principles, main contents, and major achievements of real physics. It shows that the classical physical laws (laws of motion, gravitation, electromagnetism, and thermodynamics) are all conclusions drawn from the statistics of elastic particles, which reveals the irreversibility of natural processes.

Published: April 2020

Web-Services can be referred as a family of technologies that standardized the communication of applications through world wide web in a cost-effective manner. Few of the major software vendors like IBM, Microsoft, Oracle, SAP are all embracing the web service standards into the newer versions of their applications which are web services enabled. All the constrains like cost, time, space for discovering, and e-business transactions can be solved easily by using web-services. With the introduction of these Web services design of the business application to provide service, integrating with other business entities, and conducting business transactions completely changed the working of a business organization. These web-services became a viable component in distributed E-Commerce platforms. In determining server response time, high speed communication systems along with computing capacity and network latency have become important. In web technologies a new model of architecture for distributed E-Commerce applications has been proposed which aims at integration and inter-operation between different platforms. In this paper we have proposed a model for developing an E-Commerce application using the Spring framework which helps in easy integration with other frameworks and solves most difficulties in an enterprise application development.

Authors: Guajardo Jesus , Petershack Jean , Caplow Julie , Littlefield John
Published: April 2020

Purpose: To assess whether there are differences in medical students’ (MS) knowledge acquisition after being provided a virtual patient (VP) case summary with a patient’s name and facial picture included compared to no patient’s name or image.Method: 76 MS from four clerkship blocks participated. Blocks one and three (Treatment group) were provided case materials containing the patient’s name and facial picture while blocks two and four (Control group) were provided similar materials without the patient’s name or image. Knowledge acquisition was evaluated with a multiple-choice-question examination (CQA_K).Results: Treatment group CQA_K scores were 64.6% (block one, n = 18) and 76.0% (block three, n = 22). Control group scores were 71.7%, (block two, n = 17) and 68.4% (block four, n = 19).  ANOVA F-test among the four block mean scores was not significant; F (3, 72) = 1.68, p = 0.18, η2=0.07. Only 22.2% and 27.3% of the MS from blocks one and three respectively correctly recalled the patient’s name while 16.7% and 40.9% recalled the correct final diagnosis of the patient.Conclusions: These results suggest that including a patient’s name and facial picture on reading materials may not improve MS knowledge acquisition. Corroborating studies should be performed before applying these results to the design of instructional materials.
Guyana’s paediatric training program: a global health partnership for medical education
Authors: Cameron Lita , Johnston Julie , Sparman Arnelle , Nelin Leif D , Singh Narendra , Hunter Andrea
Published: April 2020

Guyana is a low-middle income country on the northern coast of South America between Venezuela and Suriname. Guyana has relatively high child mortality and a notable gap in health care provision. As of 2011, there were no paediatricians in the public sector where approximately 90% of the population seek care. In response to this unmet need, Guyanese diaspora living in Canada, in partnership with Canadian paediatricians and the main teaching hospital, Georgetown Public Hospital Corporation (GPHC), developed a Master’s program in paediatrics. The postgraduate program was designed with adapted training objectives from the Royal College of Physicians and Surgeons of Canada and the American Board of Paediatrics. Innovative strategies to overcome the lack of qualified paediatric faculty in Guyana included web-conferencing and a volunteer North American paediatric faculty presence at GPHC with a goal of 1-2 weeks every month. By November 2016, 10 graduates will have passed through a rigorous program of assessment including a two-day final examination with an objective structured clinical examination (OSCE) component.
Assessing and Spatio-Temporal Variations of Potentially Toxic Elements in the Sediments from Lower Danube River in 2011-2017 Period
Authors: Radu Violeta-Monica , Ionescu Petra , Diacu Elena , Deak Gyorgy , Ivanov Alexandru Anton
Published: April 2020

The growing concern for most European rivers is due to pollution with potentially toxic elements (PTEs) and is of course a priority challenge for the Danube, a river that interconnects fresh water with the marine environment. The accumulation of PTEs from the Lower Danube River sediments and the potential negative effects of these chemicals on the water quality during and after the hydro-construction works carried out in the area to improve the navigation conditions have been studied in the present work. For seven years period (2011-2017), sampling campaigns from 10 monitoring sites were carried out. Sediment samples were taken from the Lower Danube River (km 375 - km 175) from the left and right banks, monthly during the construction period (2011 - 2015) and quarterly in the post-construction period (2015 - 2017). A total approximately of 1200 samples were analyzed and Cd, Cr, Cu, Pb, Zn and Ni content was determined to obtain the assessment of sediments that can influence water quality. Multivariate statistical analysis was applied to the complex data set obtained, the degree of accumulation and the distribution of these metals on the studied section was calculated. Also, the quality indicators of sediments were evaluated according to the legislation in force. The results showed that all concentrations of the monitored PTEs have recorded values over the normal values from the current legislation. On the whole, Zn has the highest concentration, while Cd has the smallest one. The order of the absolute average concentrations values found in this study is Zn ] Cu ] Cr ] Ni ] Pb ] Cd. For the Zn and Cu elements, slightly higher values were recorded compared to other heavy metals (Pb and Cd), which means that historically contaminated deposits in sediments can be remobilized and transported to the upper layers of the sediment or even be diffused in water. Generally, due to different sediment types and input levels, there is a variable contamination throughout the Danube aquatic ecosystem. The statistical analysis applied to analytic data highlighted the action of anthropogenic sources on the Danube aquatic ecosystem, showing the interdependencies between monitored indicators and seasonal influence.
Study on the Microstructural Characteristics of Some Metallic Layers Produced Using the Electrochemical Method and Thermal Spraying
Authors: Gheta Roxana Alexandra , Voiculescu Ionelia , Vasile Ion Mihai , Chisiu Georgiana
Published: April 2020

The paper presents the comparative analysis of the microstructural particularities and the superficial characteristics (microhardness and wear resistance) of 3 methods of producing composite layers on metallic support. The aim of the research was to study the possibility of replacing the hard chromium plating process by the thermal metallization process, in order to produce layers resistant to wear and corrosion. Samples produced by hard chromium plating (layers deposited by electrolysis), samples loaded by thermal metallization with electric arc and G3Si1 wire, and samples loaded by thermal metallization with oxy-gas flame and detonation (HVOF) using tungsten carbide as filler material were used in this study.Hard chromium plating allows for high wear resistance thin layers to be produced, but the process is cumbersome and polluting. Thermal metallization allows the production of composite layers, of a chemical composition selected according to the operational demands, in much shorter times and at lower costs. In order to ensure a higher adhesion and to reduce the mechanical stresses at the support-hard layer interface, an intermediate layer of nickel was deposited in the case of samples loaded by thermal metallization with wire. In the paper, the microstructures in cross-section were analysed, the chemical compositions were determined on micro-zones related to the diffusion from the support material and the microhardness in the deposited metal and in the thermally affected zones was measured. These studies have shown that composite metallic layers displaying satisfactory mechanical and microstructural characteristics can be produced using alternative methods (thermal metallization) if optimum regime parameters are chosen.

Aim: Our long-term aim is to develop a living valvular substitute using Regenerative Medicine principles, by seeding decellularized porcine heart valve scaffolds with adult stem cells and conditioning them in bioreactors before implantation. In this study, adult stem cells were isolated from sheep adipose tissue (ADSCs). However, we found it impractical to use cells immediately after propagation and thus, in order to extend their availability in time, a preservation method was needed. Methods: Adipose tissue was harvested from 6 sheep. ADSCs were isolated using enzymatic agents and cultured. The cells were tested for plasticity using chondrogenic, adipogenic and osteogenic differentiation kits and then cryopreserved in DMSO at -1400C. Viability was tested after a 3 week storage using Trypan Blue Staining. Results: Ovine ADSCs exhibited excellent plasticity and differentiation potential. An average of 18 million ADSCs were obtained from each ovine, exhibiting more than 88% viability after a 3-week cryopreservation period followed by thawing. Conclusions: DSMO cryopreservation represents a suitable method for ovine ADSCs for regenerative medicine. This method expands the usage of stem cells in vitro before they are differentiated into more specialized cells, offering large numbers of usable ADSCs with minimal cell loss at any desired time point.

The municipal reclaimed water, which often reused in circulating cooling water system, can effectively alleviate the urban water crisis. However, the reclaimed water contains a large number of microorganisms while the water environment in circulating cooling water system allows the micro-organisms to further increase. Therefore, circulating cooling water system faces slime, corrosion and other microbial problems. In this work, the microbial population structure of circulating cooling water makeup by municipal reclaimed water was investigated by using modern molecular biology DNA technology. Our results demonstrated that at the level of family, there were 17 kinds of suspended microorganisms in municipal reclaimed water, in which the dominant strain belonged to Proteobacteria, Betaproteobacteria, Methylophilales, Methylophilaceae. For the circulating cooling water without chemical agents, 13 kinds of suspended bacterias and 36 kinds of immobilized bacteria were detected, in which the dominant strain respectively was Comamonadaceae and Pseudomonadaceae which belonging to Proteobacteria Betaproteobacteria. After adding chemical agents, the number of suspended bacteria increased to 26 kinds and the distribution of bacteria species was even more. And the dominant strain become Staphylococcaceae, which belonged to Firmicutes, Bacilli, Bacillales, the reason for this was the sharply increase of TOC and TP after adding scale and corrosion inhibitors. Corrosion of instrumentation and pipe network systems caused by microorganisms is particularly complicated in circulating cooling water systems and even in whole reclaimed water utilization systems. The corrosion mechanism and corrosion process caused by different microorganisms are different. Therefore, it is very important to explore the composition of microorganisms in reclaimed water to study the corrosion of microorganisms. Based on the study of microbial population structure in municipal reclaimed water, this paper explores the microbial population structure and dominant species in the water in response to the specific situation in which reclaimed water is reused in the circulating cooling water system. At the same time, it also provides some research suggestions for the future research on the corrosion caused by microorganisms in the reuse of recycled water.

The spatially resolved star formation histories are studied for 32 normal star-forming galaxies drawn from the Spitzer Extended Disk Galaxy Exploration Science survey. At surface brightness sensitivities fainter than 28 mag arcsec−2, the new optical photometry is deep enough to complement archival ultraviolet and infrared imaging and to explore the properties of the emission well beyond the traditional optical extents of these nearby galaxies. Fits to the spectral energy distributions using a delayed star formation history model indicate a subtle but interesting average radial trend for the spiral galaxies: the inner stellar systems decrease in age with increasing radius, consistent with inside-out disk formation, but the trend reverses in the outermost regions with the stellar age nearly as old as the innermost stars. These results suggest an old stellar outer disk population formed through radial migration and/or the cumulative history of minor mergers and accretions of satellite dwarf galaxies. The subset of S0 galaxies studied here show the opposite trend compared to what is inferred for spirals: characteristic stellar ages that are increasingly older with radius for the inner portions of the galaxies, and increasingly younger stellar ages for the outer portions. This result suggests that either S0 galaxies are not well modeled by a delayed-τ model, and/or that S0 galaxies have a more complicated formation history than spiral galaxies.

The physics regulating star formation (SF) in Hickson Compact Groups (HCG) has thus far been difficult to describe, due to their unique kinematic properties. In this study, we expand upon previous works to devise a more physically meaningful SF relation able to better encompass the physics of these unique systems. We combine CO(1–0) data from the Combined Array from Research in Millimeter Astronomy to trace the column density of molecular gas

and deep Hα imaging taken on the Southern Astrophysical Research Telescope tracing

to investigate SF efficiency across face-on HCG, NGC 7674. We find a lack of universality in SF, with two distinct sequences present in the

–

plane; one for inside and one for outside the nucleus. We devise an SF relation based on the multi-freefall nature of gas and the critical density, which itself is dependent on the virial parameter

, the ratio of turbulent to gravitational energy. We find that our modified SF relation fits the data and describes the physics of this system well with the introduction of a virial parameter of about 5–10 across the galaxy. This

leads to an order-of-magnitude reduction in SFR compared to

systems.

We use K-band spectroscopic data from the Multi-Object Spectroscopic Emission Line survey to analyze the kinematic properties of galaxies at z > 3. Our sample consists of 34 galaxies at 3.0 < z
spec < 3.8 between 9.0 < 

 < 11.0. We find that galaxies with

 > 10.2 at z > 3 have 56 ± 21 km s−1 lower integrated velocity dispersion compared to galaxies at z ≃ 2 of similar stellar mass. Massive galaxies at z > 3 have either a flat or declining star formation history (SFH), whereas similar stellar mass galaxies at z ∼ 2.0 exhibit a slight peak in the past 500 Myr. Comparing with the IllustrisTNG cosmological simulation, we find that (i) the dynamical mass of massive galaxies in simulations (

> 10.0) increases by ∼0.1 dex at a fixed stellar mass between z = 2.0–3.0, and (ii) dynamical mass growth is coupled with a rapid rise in the ex situ stellar mass fraction (stars accreted from other galaxies) for massive galaxies at z < 3.5. We speculate that the rising contribution of ex situ stellar mass to the total stellar mass growth of massive galaxies is driving the higher integrated velocity dispersion and rising SFHs of massive galaxies at z ∼ 2.0 compared to galaxies of similar stellar masses at z > 3.
