Tracing Microplastics in Municipal Potable Water Across Residential Buildings
Creators: name: Tran, Jimmy
Publisher: name: University of Massachusetts Amherst
Year: 2023

Limited research on microplastics makes it increasingly difficult to measure the potential dangers of their toxicological effect on humans and the environment. Today, evidence has revealed that microplastics have been located in highly remote areas of the world. There are few studies that examine the movement of microplastics within urban landscapes and even fewer that observe different communities within cities. To this end, a study was devised that utilized filtration, dehydration, and Laser Direct Infrared Spectroscopy to monitor drinking water microplastics found in residential buildings across different communities.
Houses and apartments of low and high-income at different distances from the nearest water treatment plant were considered. Comparisons between format differences between housing units were made possible by creating a ratio between rent and the square footage of the unit. Samples were extracted from kitchen faucets for their high impact on cooking and human consumption. While there was no significant difference between distance, income level, and building structure some factors had a stronger influence on microplastic count than others. Using a general linear model, it was found that distance had the greatest effect on microplastic count followed by building type and then income levels. The greater the distance from a water treatment plant the fewer microplastics one was exposed to. Microplastics were found to be more abundant in apartments as opposed to houses. A weak positive correlation between income level and the number of microplastics was found but was not significant enough to state that income played a role in microplastic count. This is interpreted as microplastics having no discrimination on one’s socioeconomic status. As everyone, no matter their background is affected by microplastics, it is recommended that more research be conducted in order to confirm whether other building types and other factors have an influence on microplastic exposure.

We refer to the unitary group $G$ of $V$ as the local unitary (LU) group. We fix an orthonormal (o.n.) basis $\ket{v_1},...,\ket{v_M}$ of $V$. Then the Slater determinants $e_{i_1,...,i_N}:= \ket{v_{i_1}\we v_{i_2}\we...\we v_{i_N}}$ with $i_13. If $M$ is even, the well known BCS states are not LU-equivalent to any single occupancy state. Our main result is that for N=3 and $M$ even there is a universal subspace $\cW\subseteq\cS$ spanned by $M(M-1)(M-5)/6$ states $e_{i_1,...,i_N}$. Moreover the number $M(M-1)(M-5)/6$ is minimal.

Molecular Phylogenetics and Geometric Morphometrics Reveal Possible Cryptic Species Within the Solitary Bees Melissodes agilis and M. trinodis (Hymenoptera: Apidae)
Creators: name: Roch, Justin C.
Publisher: name: University of Massachusetts Amherst
Year: 2023

Recent concerns of declining bee populations have highlighted the importance of monitoring wild bees, but bee community assessments are hampered by species complexes that are difficult to identify. Bees in the genus Melissodes are often considered challenging to identify to species, with two widespread North American species, M. agilis Cresson and M. trinodis Robertson, being particularly difficult due to similar morphology, geographic ranges, and preferred floral hosts. These two species exhibit characteristics of cryptic species complexes, raising the possibility that our current understanding of their taxonomy is incomplete. We conducted a study to clarify the species boundaries within this complex, and to test if geometric morphometrics could be used to differentiate its member taxa. We sequenced fragments of the mitochondrial COI gene from 112 M. agilis/trinodis specimens, and integrated them into a phylogeny based on published reference sequences of over 70 Melissodes species. We additionally landmarked forewing venation for 102 of these specimens, tested if forewing morphometrics was associated with sex and phylogenetic clade, and tested if forewing morphometrics could accurately assign specimens to their proper clade and sex. Phylogenetic reconstructions resulted in nearly all specimens being assigned to three primary clades, with one clade containing reference sequences for M. agilis and M. trinodis, and two clades appearing to be undetermined cryptic taxa. Forewing morphometrics differed between clades and sexes, and was able to assign specimens to their proper clade or sex with over 80% accuracy, although accuracy of classification to clade declined to between 33-93% after cross-validation. Our results suggest the existence of cryptic diversity within M. agilis and M. trinodis, and indicate that forewing morphometrics can characterize some of this diversity. M. agilis and M. trinodis may comprise a complex of 3-5 cryptic species, but whether these are described or undescribed species is unknown. Also unclear is the degree to which the potential cryptic species contribute to the economically important sunflower pollination services currently considered to be conducted by M. agilis and M. trinodis. We encourage additional study of this complex to determine the nature of this cryptic diversity and resolve the taxonomic questions this study has raised.
A Latent Profile Analysis of Four Characteristics of Intimate Partner Violence and Associations with Posttraumatic Stress Symptoms
Creators: name: Uribe, Ana
Publisher: name: University of Massachusetts Amherst
Year: 2023

Intimate partner violence (IPV) is a prevalent potentially traumatic experience that increases risk for posttraumatic stress symptoms (PTSS). However, there is still considerable heterogeneity in PTSS among women exposed to IPV. Research on IPV has examined the ways in which different characteristics of IPV exposure have separately related to risk for PTSS, specifically the type (physical, psychological, economic, sexual), frequency (number of incidents), severity (minor, severe), and mode of violence (in-person, online). However, it may be important to examine how the integration of these characteristics of IPV differ across ���������������������� ���� ������ ���� ������������ �������������������� �������������� ���������� The current study integrated these characteristics to assess classes of IPV and the relevant associations between concurrent and future PTSS. 264 women between the ages of 18-24 (Mage=20.41, SD=2.99) were recruited as part of a greater longitudinal study examining the relationship between PTSS and co-occurring psychopathology following exposure to IPV and/or sexual assault in the past year. Four classes of IPV across four characteristics of IPV (type, severity, frequency, and mode) were identified with latent class analysis (LCA). (1) history of both mild and severe psychological, physical, and sexual IPV in person and online, (2) history of mild and severe psychological IPV and mild sexual IPV occurring in person and online, (3) history of mild psychological IPV occurring in person and online, (4) past history of one type of IPV occurring in person. Class membership and concurrent and future PTSS were found to be associated with class membership.

description: Recommender systems based on latent factor models have been effectively used for understanding user interests and predicting future actions. Such models work by projecting the users and items into a smaller dimensional space, thereby clustering similar users and items together and subsequently compute similarity between unknown user-item pairs. When user-item interactions are sparse (sparsity problem) or when new items continuously appear (cold start problem), these models perform poorly. In this paper, we exploit the combination of taxonomies and latent factor models to mitigate these issues and improve recommendation accuracy. We observe that taxonomies provide structure similar to that of a latent factor model: namely, it imposes human-labeled categories (clusters) over items. This leads to our proposed taxonomy-aware latent factor model (TF) which combines taxonomies and latent factors using additive models. We develop efficient algorithms to train the TF models, which scales to large number of users/items and develop scalable inference/recommendation algorithms by exploiting the structure of the taxonomy. In addition, we extend the TF model to account for the temporal dynamics of user interests using high-order Markov chains. To deal with large-scale data, we develop a parallel multi-core implementation of our TF model. We empirically evaluate the TF model for the task of predicting user purchases using a real-world shopping dataset spanning more than a million users and products. Our experiments demonstrate the benefits of using our TF models over existing approaches, in terms of both prediction accuracy and running time.

description: This thesis deals with the theoretical description of photonic waveguides for the simulation of non-Abelian gauge fields as well as the study of non-Hermitian systems. The artifical gauge fields emerge from a closed, adiabatic curve in the parameter manifold of a waveguide system with degeneracies. An optimisation process allows to find ideal parameters of an experimental implementation. Additionally, two Lie-algebraic methods that solve the quantum master equation of an arbitrary, lossy waveguide system are developed, which allow to study non-Hermitian systems, e.g. parity-time-symmetry.

Bog Turtle (Glyptemys muhlenbergii) Population Dynamics and Response to Habitat Management in Massachusetts
Creators: name: Vineyard, Julia
Publisher: name: University of Massachusetts Amherst
Year: 2023

The Bog Turtle (Glyptemys muhlenbergii) is a federally threatened species that occupies isolated pockets of open-canopy fens. This long-lived species is susceptible to habitat loss and degradation; thus, the conservation of known populations and management of their habitat is critical to the species’ survival. Long-term (multi-decadal) assessment is important for determining population trends and responses to ongoing habitat management. I assessed population demographics (abundance, survival) and spatial distribution (home range) of two Bog Turtle populations in Massachusetts that have been managed since the late 1990s by treating invasive species, thinning woody vegetation, and mitigating flooding. The results of this study were compared to two previous studies conducted in 1994–1997 and 2005–2009 to evaluate the response to habitat management. Estimates of adult population abundance increased from the first study period (Site 1 X̅= 37.3 ± 10.4, Site 2 X̅= 36.2 ± 3.2) to the last study period (Site 1 X̅= 65.1 ± 17.9, Site 2 X̅= 42.5 ± 10.9) across both sites. Estimates of annual survival across all study periods remained above 90% at Site 1 and were 100% for two years at Site 2. I constructed 95% minimum convex polygon (MCP) and 95% kernel density estimation (KDE) home ranges for 71 turtles. At Site 1 there was no significant influence of the study period on home range estimates. The increase in abundance estimates, high survival, and stable home range sizes at Site 1 suggest that ongoing management has maintained quality habitat. At Site 2, the average home range size decreased by approximately half after the first study period in response to flooding but increased in the current study. Fluctuations in population abundance, and home range size at Site 2 throughout the study period reflect the cycles of habitat degradation and habitat management. My results indicate that habitat management efforts implemented since the late 1990s have provided quality habitat for the two Bog Turtle populations in Massachusetts while also mitigating long-term negative impacts on the populations. This further supports the need for long-term analysis of Bog Turtle populations, especially at sites where active habitat management is occurring.

Optimization of Optical Properties of Plant-Based Foods
Creators: name: Wannasin, Donpon
Publisher: name: University of Massachusetts Amherst
Year: 2023

Plant-based foods are considered to be more sustainable food source than animal-based foods due to their lower environmental impact. However, there is a challenge in producing plant-based foods with similar taste, texture, and appearance to animal-based products to meet consumers expectations. The appearance, which includes color, is the first sensory attribute consumers experience of foods, and so it influences consumers’ buying decisions. Food colorants are added to match the color of plant-based foods with animal-based ones. The food colorant choice is shifting toward natural colorants due to their perceived health benefits and clean-label aspects. Therefore, this study aimed to optimize the optical properties of plant-based foods using natural food colorants. Initially, the impact of natural pigments that selectively absorb light (turmeric, red beet, and butterfly pea flower) and colloidal particles that selectively scatter light (oil droplets) on the optical properties of model plant-based oil-in-water emulsions was investigated. It was found the pigment and oil droplet characteristics, including pigment type and concentration, and droplet size and concentration, could be adjusted to modulate the chromaticness or lightness of emulsions by altering light absorption and scattering effects. This knowledge is useful to optimizing the appearance of plant-based foods by adjusting these parameters. Then, natural pigments with three primary colors (yellow, red, and blue) were blended to mimic the color of animal-based products (raw meat, cooked meats, egg, and cheese). A color matching model developed from Kubelka-Munk and color theories was then used to determine the optimum ratio of each colorant needed to match the spectral reflectance of animal-based products. The methodology developed was able to optimize the color of model plant-based emulsions to that of different food matrices. The improved understanding of the optical properties of natural pigments and color matching theory developed in this study should help to formulate plant-based foods with more similar appearances to animal-based products, thereby increasing consumers’ acceptance of plant-based foods.

GREENHOUSE GASES AND HYDROCLIMATE VARIABILITY IN THE CARIBBEAN: A NEW SPELEOTHEM RECORD SHEDDING LIGHT ON MILLENNIAL AND ORBITAL-SCALE CHANGES
Creators: name: Zhang, Meilun
Publisher: name: University of Massachusetts Amherst
Year: 2023

Hydroclimate evolution in the northern Caribbean region has been investigated by several studies, but they offer contradicting results and none of them cover a full glacial-interglacial transition to examine orbital climate forcing. Here we present refined U-Th dating and oxygen isotope (δ18O) data from a stalagmite named Katún collected from Rio Secreto cave in the Yucatan Peninsula that discontinuously spans the time interval between 198 thousand years (kyr) before present (BP) to 320 kyr BP. Stalagmite δ18O is interpreted to reflect precipitation amount variability as established by previous studies from this cave. On orbital timescales, we identified marine isotope stages (MIS) 7, 8, and 9 in the Katún stalagmite δ18O record. The average stalagmite δ18O value during MIS 7 and 9 interglacial intervals is ~-4.5‰, suggesting wetter conditions than the glacial MIS 8 with an average δ18O value of ~-3‰. The stalagmite δ18O record exhibits higher amplitude δ18O and thus precipitation variability, and an increase in the frequency and intensity of drought events during the drier glacial interval. The record suggests a strong link between atmospheric greenhouse gases, CO2 andCH4, and precipitation variability in the Caribbean, which affects hydroclimate via changes in tropical Atlantic sea surface and air temperature. We propose that changes in North Atlantic high latitude climate are connected to regional hydroclimate, as evidenced by concurrent Caribbean precipitation and atmospheric methane variability, similar to Greenland D-O events. The broader implication of this study is that human activities may alter the fundamental relationship between Caribbean hydroclimate and greenhouse gases, which have likely sustained tropical wetlands and modulated methane production for millennia.

description: The "green" acidic clinoptilolite (HCLIN) samples were prepared by decomposition of an ammonium exchanged natural zeolite NH4CLIN at different temperatures. And their crystalline, morphology, porosity, acidity were investigated. The dehydroxylation due to thermal treatment causes fading away of the weak Brønsted acid sites (BS). Samples' activity in etherification of glycerol and tert-butanol will be decreased if it were calcined at a higher temperature or in a long time at 300°C. Besides, the glycerol conversion and the selectivity of di-ether as a renewable fuel additive were enhanced.
Initial Paleoenvironmental Evidence from the Outer Yukon-Kuskokwim Delta, Alaska
Creators: name: Allen, Hunter T
Publisher: name: University of Massachusetts Amherst
Year: 2023

Southwestern Alaska is a critically understudied region of Beringia, highlighted by the lack of paleoenvironmental reconstructions of the Yukon-Kuskokwim Delta (YK Delta). This sub-arctic region is a joint deltaic coastal lowland environment, home to 50 Yup’ik and Cup’ik communities. Anthropogenic climate change dramatically impacts the landscape. Increases in the intensity and occurrence of coastal flooding, the thaw of permafrost and tundra wildfire events have directly affected community resilience and their subsistence way of life. The YK Delta also contributes to the global atmospheric carbon budget as the region’s discontinuous permafrost thaws releasing stored carbon. These issues necessitate the filling of the regional paleoenvironmental knowledge to properly inform native populations and predict future changes to the landscape.
Working with two communities on the outer YK Delta, namely, Kongiganak and Mekoryuk, this thesis presents initial paleoenvironmental studies which contribute to our understanding of the impacts of climate change on this region. The first effort documents the development of a loess plateau on the YK Delta during the Last Glacial Period (115,000 – 11,700 years ago), specifically during Marine Isotope Stage III (60,000 – 25,000 years ago), described in Chapter 2. This topic was developed from exposures at Kongiganak and Mekoryuk, and helps to refine the relative sea level history and aeolian processes of the YK Delta. Other efforts on Nunivak Island consist of preliminary results from the first late Holocene lacustrine reconstruction and the first attempt to provide context to coastal dune geomorphology, highlighted in Chapter 3. These efforts help to establish regional paleoenvironmental conditions in the late Holocene, methodology for future sampling, and provide important estimates of long-term coastal erosion.

description: This thesis contributes to the convergence theory of Krylov subspace eigensolvers for discretized self-adjoint elliptic differential operators. A central topic refers to a priori convergence estimates with weak assumptions and concise bounds, which can reasonably predict the convergence rate, in particular for clustered eigenvalues. By avoiding the dependence on current approximate eigenvalues, such estimates significantly improve certain state-of-the-art estimates with regard to their sharpness and applicability.
Modeling the Effects of Forest Management Practices on Ecohydrologic Processes in the Antalya River Watershed of Turkey
Creators: name: Arslan, Hilal
Publisher: name: University of Massachusetts Amherst
Year: 2023

This study focuses on modeling the effects of forest management practices on eco-hydrological processes in the Antalya River Watershed, Turkey. With increasing global pressures from urbanization, deforestation, and climate change affecting water resources and ecosystems, understanding the impact of forest management on vital water sources is essential for sustainable water resource management and ecosystem protection. The Soil and Water Assessment Tool (SWAT) model assessed the hydrological impacts of afforestation and urban forest scenarios in the Antalya River Watershed—the model's parameterization, sensitivity analysis, and calibration phases accurately simulated base watershed processes. The validation process confirmed the accuracy of results, particularly in yearly time steps, providing a comprehensive understanding of the watershed's water management strategies. The results indicate that the afforestation scenario reduced surface runoff and increased lateral flow, decreasing erosion risk and improving groundwater recharge. Although soil evaporation and plant transpiration decreased, the increase in “revap” values highlighted higher water vapor emission from the soil, contributing to atmospheric water cycle processes. Similarly, the urban forest scenario resulted in decreased surface discharge and increased groundwater flow, indicating improved water retention and recharge capabilities. The increased evapotranspiration demonstrated the positive influence of trees and vegetation on the water cycle and atmospheric processes, emphasizing the significance of urban forest applications as valuable nature-based solutions for sustainable water resource management and conservation. In conclusion, implementing afforestation and urban forest initiatives can contribute to ecologically sound utilization of water supplies, enhance ecosystem functioning, and foster resilience in the face of environmental obstacles. The study emphasizes the potential benefits of afforestation and expanding green spaces in promoting sustainable water resources and mitigating erosion and flooding risks. The results of this study provide a scientific basis for policymakers and stakeholders to consider afforestation practices as a vital component of water resource management and watershed conservation strategies.
Memories of Hope and Loss: “kerhi maa ne bhagat singh jameya”
Creators: name: Bano, Sheher
Publisher: name: University of Massachusetts Amherst
Year: 2023

My Masters thesis focuses on socialist Indian freedom fighter Bhagat Singh’s memory in contemporary Pakistani Punjab. I use the analytical category of memory to argue that Bhagat Singh is invoked by various groups and individuals, specifically those who identify as leftists or Marxists, in contemporary Pakistan to serve a range of political purposes. My analysis particularly sheds light on how activists and writers use the figure of Bhagat Singh to highlight the erasure of regional and lingual identities in Pakistan. Their remembrances underline a perceived historical injustice; the imposition of a national identity based on Urdu language and Sunni Muslim-ness, which tended to marginalize Punjabi ethno-lingual identities. Using my ethnographic research, I further argue that Bhagat Singh and his afterlives in leftist progressive narratives also capture the tensions and differences among the Punjabi intellectuals and activists themselves. Due to the lack of adequate archival sources, my research draws heavily on oral history and contemporary Punjabi poetry and prose that I meticulously collected during my trips to Lahore in the past two years. I transcribed and translated this material from Punjabi into English on my own. Finally in my analysis of gendered literary language, I also demonstrate how mourning, and hope coexist in the Punjabi contemporary emancipatory imagination. Such overlaps illustrate how the past is continuously in dialogue with the present. 
Elucidating the Priming Mechanism of ClpXP Protease by Single-Domain Response Regulator CpdR in Caulobacter crescentus
Creators: name: Barker, Kimberly E
Publisher: name: University of Massachusetts Amherst
Year: 2023

In Caulobacter crescentus, progression through the cell cycle is regulated by the AAA+ protease ClpXP, and there are several classes of cell-cycle substrates that require adaptors in order to be degraded. CpdR, a single domain-response regulator, binds the N-terminal domain of ClpXP and primes the protease for degradation of downstream factors (Lau et al., 2015). The ability of CpdR to bind ClpX is regulated by its phosphorylation state. In the unphosphorylated state, CpdR binds ClpXP and guides its localization to the cell pole during the swarmer to stalked transition, where CpdR is mediates degradation of substrates such as PdeA. Phosphorylation of response regulator receiver domains requires magnesium as a cofactor to stabilize the phosphorylated aspartate and reciprocally, phosphorylated receiver domains bind magnesium more effectively. While it is understood that CpdR primers ClpX for substrate degradation, the mechanism by which it does so has remained unclear. Using CollabFold, we identified putative residues involved in CpdR-ClpX binding and validated them using a BACTH screening. In vitro, we characterized the role that magnesium plays in regulating CpdR binding to ClpX. In this work, we directly test the role of magnesium in CpdR priming of ClpXP to show that magnesium may play a regulatory role in CpdR-mediated degradation, and thus binding to ClpX. We identify residues in ClpX that seem to be important for CpdR binding, which prior to this work was not clear.

description: (Abridged) We describe a new method to extract spectra of stars from observations of crowded stellar fields with integral field spectroscopy (IFS). Our approach extends the well-established concept of crowded field photometry in images into the domain of 3-dimensional spectroscopic datacubes. The main features of our algorithm are: (1) We assume that a high-fidelity input source catalogue already exists and that it is not needed to perform sophisticated source detection in the IFS data. (2) Source positions and properties of the point spread function (PSF) vary smoothly between spectral layers of the datacube, and these variations can be described by simple fitting functions. (3) The shape of the PSF can be adequately described by an analytical function. Even without isolated PSF calibrator stars we can therefore estimate the PSF by a model fit to the full ensemble of stars visible within the field of view. (4) By using sparse matrices to describe the sources, the problem of extracting the spectra of many stars simultaneously becomes computationally tractable. We present extensive performance and validation tests of our algorithm using realistic simulated datacubes that closely reproduce actual IFS observations of the central regions of Galactic globular clusters. We investigate the quality of the extracted spectra under the effects of crowding. The main effect of blending between two nearby stars is a decrease in the S/N in their spectra. The effect increases with the crowding in the field in a way that the maximum number of stars with useful spectra is always ~0.2 per spatial resolution element. This balance breaks down when exceeding a total source density of ~1 significantly detected star per resolution element. We close with an outlook by applying our method to a simulated globular cluster observation with the upcoming MUSE instrument at the ESO-VLT.

description: Molekularbiologische Stammvergleichsmethoden sind bislang kein Bestandteil der Routinediagnostik von Mastitissekreten in Deutschland. Diese Methoden wurden eingesetzt um Verbreitungswege von Mikroorganismen innerhalb einer Herde nachzuvollziehen, die Unterscheidung zwischen kontagiösen und nichtkontagiösen Infektionsverläufen zu treffen und den Anteil persistierender Infektionen unter wiederkehrenden Infektionen zu ermitteln. Die Ergebnisse zeigen, dass Stammvergleichstechniken das Potential haben bei einzelbetrieblichen Mastitisproblemen erheblich zur Lösung beizutragen.

ANTIFASCIST AUTOBIOGRAPHICAL WRITING BY THREE SOUTHERN EUROPEAN WOMEN WRITERS: NATÁLIA CORREIA, CONCHA ZARDOYA, AND LUDOVICA RIPA DI MEANA
Creators: name: Beasley, Jessica R
Publisher: name: University of Massachusetts Amherst
Year: 2023

This thesis puts three antifascist writers in dialogue: Concha Zardoya, Natália Correia, and Ludovica Ripa di Meana. It does so based on their similarities as women who lived in Southern European fascist regimes, who wrote autobiographical poetry books about those regimes. Comparing and qualifying the regimes based on Umberto Eco’s Ur-Fascism, in which he highlights common “family resemblance” characteristics of fascist regimes, I set up the positionality of each women within her specific milieu. I then discuss the resulting poetry books, which all utilize a multi-temporal, teleological construction of the regime based on the writer’s own memory as someone who lived through it. Based on Michel-Roph Trouillot’s framing of history, I study how each writer uses this construction to move from agent/object of history to subject of history, thus granting herself the authority that was denied to her during the regime.

Early Childhood Emotion Regulation Strategy Articulation, its Neurophysiological  Correlates, and Association with Psychopathology
Creators: name: Bivins, Zachary
Publisher: name: University of Massachusetts Amherst
Year: 2023

Deliberate Emotion Regulation (ER), the effortful regulation of emotions, is strongly linked to psychopathology. In adults, deliberate ER is often experienced as a self-narrative, such as reappraising a negatively perceived scenario. However, researchers have yet to study how young children articulate deliberate ER strategies, whether these strategies relate to real-time ER neurophysiological processes, and how they are associated with psychopathology. Thus, from an existing sample of 59 children, I aimed to examine preschool-aged children’s verbally articulated ER strategies prior to a frustration challenge, and related these strategies to subsequent neural and physiological responses to frustration and psychopathology. I categorized children’s responses into two groups: those who articulated any emotion regulation strategy (i.e., “strategy”) and those who did not articulate a strategy (i.e., “no strategy”). We found that about 70% of children in this age range were able to articulate an emotion regulation strategy. Children who articulated a strategy had lower psychophysiological stress during a frustration task and fewer parent-reported ADHD inattention symptoms than children who did not articulate a strategy. There were no observed differences between groups for Prefrontal Cortex (PFC) activation, parent-reported externalizing symptoms, or parent-reported irritability symptoms. To our knowledge, this study is the first to provide evidence that emotion regulation strategy articulation is an emerging skill, and that children who are able to articulate emotion regulation strategies are also able to change their physiological stress in response to a negative emotion challenge and have fewer symptoms of psychopathology.
Simplified quantum bit commitment using single photon nonlocality

description: We simplified our previously proposed quantum bit commitment (QBC) protocol based on the Mach-Zehnder interferometer, by replacing symmetric beam splitters with asymmetric ones. It eliminates the need for random sending time of the photons; thus, the feasibility and efficiency are both improved. The protocol is immune to the cheating strategy in the Mayers-Lo-Chau no-go theorem of unconditionally secure QBC, because the density matrices of the committed states do not satisfy a crucial condition on which the no-go theorem holds.

description: Excerpts from the report: With the adoption of pallet boxes by the apple industry, the cooling of the fruit in these large containers became a problem of paramount importance. Apple producers and storage and packinghouse operators need to know the cooling rates of apples stored in pallet boxes of various designs and the effects on cooling of different stacking arrangements. Cooling studies were undertaken, some covering test pallet boxes, and some covering those in commercial use, to determine the design and arrangement which would permit the maximum cooling rate of fruit. Cooling rates and cold-storage-room designs for use with pallet boxes were compared with those for the standard 1-bushel capacity wooden box.

description: In an AP-HTPB propellant microstructure, the local strain rate depends on the AP crystal size and the material, while the local temperature rate depends on the impact velocity, AP crystal size, and the material. Larger AP crystals lead to higher local strain rates and higher local temperature rates, which means hot spots are more likely to occur in AP-HTPB propellants with more large AP crystals.
