description: Absolute spectrophotometric measurements of diffuse radiation at 1 μm to 2 μm are crucial to our understanding of the radiative content of the Universe from nucleosynthesis since the epoch of reionization, the composition and structure of the Zodiacal dust cloud in our solar system, and the diffuse galactic light arising from starlight scattered by interstellar dust. The Low Resolution Spectrometer (LRS) on the rocket-borne Cosmic Infrared Background Experiment (CIBER) is a λ/ Δλ\sim 15-30 absolute spectrophotometer designed to make precision measurements of the absolute near-infrared sky brightness between 0.75 μm < λ< 2.1 μm. This paper presents the optical, mechanical and electronic design of the LRS, as well as the ground testing, characterization and calibration measurements undertaken before flight to verify its performance. The LRS is shown to work to specifications, achieving the necessary optical and sensitivity performance. We describe our understanding and control of sources of systematic error for absolute photometry of the near-infrared extragalactic background light.

Digital micrography
Creators: name: Maharik, Ron Israel
Publisher: name: University of British Columbia
Year: 2011

description: This work is concerned with computer-assisted generation of text art. Specifically, we consider an artistic style known as micrography, in which complex images are constructed from lines of tiny, readable text. Traditionally created by trained scribes and requiring immense amounts of effort, micrography has in recent years crossed over into the digital domain, with modern artists adapting the style in various ways and using it to convey their own message. Unfortunately, creating micrography with standard digital graphic design techniques remains a tedious and frustrating exercise. The method proposed here is capable of automating the work-intensive aspects of micrography, while still keeping the designer in control of the overall look and feel of the result. For artists, this means they can now rapidly experiment with different designs in a way that would be infeasible using traditional digital techniques. We begin with an analysis of the aesthetic properties of text flow that make for a visually appealing micrography. Observing that some of these requirements are shared with well-studied problems in computer graphics such as parameterization and quadrangulation, we base our solution on the popular framework of smooth fields, augmenting it with a novel approach to boundary constraint design for planar shapes. The result is a system that lets artists generate beautiful micrography in a matter of minutes, automatically optimizing for aesthetic appeal and readability while also allowing for intuitive manual intervention.

description: The Heun functions have wide application in modern physics and are expected to succeed the hypergeometrical functions in the physical problems of the 21st century. The numerical work with those functions, however, is complicated and requires filling the gaps in the theory of the Heun functions and also, creating new algorithms able to work with them efficiently. We propose a new algorithm for solving a system of two nonlinear transcendental equations with two complex variables based on the Müller algorithm. The new algorithm is particularly useful in systems featuring the Heun functions and for them, the new algorithm gives distinctly better results than Newton's and Broyden's methods. As an example for its application in physics, the new algorithm was used to find the quasi-normal modes (QNM) of Schwarzschild black hole described by the Regge-Wheeler equation. The numerical results obtained by our method are compared with the already published QNM frequencies and are found to coincide to a great extent with them. Also discussed are the QNM of the Kerr black hole, described by the Teukolsky Master equation.

I clarify the role of these two expressions in different contexts and show how E=TS is also closely related to the Noether charge arising from the boundary term of the Einstein-Hilbert action.

description: Non-committing encryption (NCE) is a type of public key encryption which comes with the ability to equivocate ciphertexts to encryptions of arbitrary messages, i.e., it allows one to find coins for key generation and encryption which “explain” a given ciphertext as an encryption of any message. NCE is the cornerstone to construct adaptively secure multiparty computation [Canetti et al. STOC’96] and can be seen as the quintessential notion of security for public key encryption to realize ideal communication channels. A large body of literature investigates what is the best message-to-ciphertext ratio (i.e., the rate) that one can hope to achieve for NCE. In this work we propose a near complete resolution to this question and we show how to construct NCE with constant rate in the plain model from a variety of assumptions, such as the hardness of the learning with errors (LWE), the decisional Diffie-Hellman (DDH), or the quadratic residuosity (QR) problem. Prior to our work, constructing NCE with constant rate required a trusted setup and indistinguishability obfuscation [Canetti et al. ASIACRYPT’17].

description: We search for resonant production of tt pairs in 4.8 fb^{-1} integrated luminosity of ppbar collision data at sqrt{s}=1.96 TeV in the lepton+jets decay channel, where one top quark decays leptonically and the other hadronically. A matrix element reconstruction technique is used; for each event a probability density function (pdf) of the ttbar candidate invariant mass is sampled. These pdfs are used to construct a likelihood function, whereby the cross section for resonant ttbar production is estimated, given a hypothetical resonance mass and width. The data indicate no evidence of resonant production of ttbar pairs. A benchmark model of leptophobic Z \rightarrow ttbar is excluded with m_{Z'} < 900 GeV at 95% confidence level.

description: Most calculations of quantum corrections in supersymmetric theories are made with the dimensional reduction, which is a modification of the dimensional regularization. However, it is well known that the dimensional reduction is not self-consistent. A consistent regularization, which does not break the supersymmetry, is the higher covariant derivative regularization. However, the integrals obtained with this regularization can not be usually calculated analytically. We discuss application of this regularization to the calculations in supersymmetric theories. In particular, it is demonstrated that integrals defining the beta-function are possibly integrals of total derivatives. This feature allows to explain the origin of the exact NSVZ beta-function, relating the beta-function with the anomalous dimensions of the matter superfields. However, integrals for the anomalous dimension should be calculated numerically.

description: There are several well-known constructions of new polytopes from old, such as the pyramid construction. We define a new local construction on abstract polytopes, called digonal contraction, which allows digonal sections to be removed by merging their two edges into a single edge. This contraction also extends to the question of contracting an edge of a polytope by merging its two vertices. Digonal contraction cannot be applied arbitrarily; we present necessary and sufficient conditions for its use. Digonal contraction also has interesting interactions with another new construction, the k-bubble construction introduced by Helfand, which we describe.

description: Bullying is a pervasive problem worldwide. Children and adolescents who are victimized, perpetrate bullying, or both experience more negative consequences to their mental health than those who are not involved. It is important to understand the students involved in bullying, as well as the process through which bullying exerts its effect. The stress process model is a general orienting framework for understanding the influence that bullying can have on mental health (i.e., emotional agitation or anxiety/anger). This model suggests that the personal resources of peer social support and self-esteem may influence the stress process by acting as either mediators, moderators, or both (i.e., structural amplification). The dual purpose of this study was to examine student involvement in bullying as well as apply the stress process model to the experiences of a nationally representative random sample of 1001 Canadian youth aged 10 to 17. First, Latent Class Analysis (LCA) was used to identify groupings of students involved in bullying. Four classes emerged across four forms of bullying (physical, verbal, social, cyber) including students who 1) primarily bullied others, 2) were primarily victimized, 3) both bullied others and were victimized, as well as those who 4) did not engage in bullying (i.e., uninvolved). Second, using Structural Equation Modelling (SEM), the stress process model was applied to the relationship between bullying and emotional agitation. The personal resources of peer social support and self-esteem were examined as both mediators and moderators. The results support a partial mediation model: peer social support and self-esteem were pathways through which bullying involvement exerted an effect on anxiety and anger. Although moderation was not supported, a main effect of peer social support and self-esteem was found. Effectively, these personal resources were found to have a positive influence on students' experiences of anxiety and anger, regardless of their involvement in bullying. The process of structural amplification was not supported. Taken together, these results provide some support for the application of the stress process model to the relationship between bullying involvement and emotional agitation. Implications for counselling psychologists as well as the field of bullying prevention, intervention, and research are discussed.

Publisher: name: University of Calgary

description: Bibliography: p. 116-118
description: In Canada the responsibility of protecting human research subjects rests primarily with research ethics boards (REBs). The REB's internal dynamics and its external relationships with the research community, other REBs, and the REB's own home institution are central to its task. This study identified and described foundational elements, both internal and external to an index REB, and contextual elements which impact each of these relationships. Moreover, how REB members understand the board's role and the challenges it faces is largely shaped by these relationships and influencing factors. This study also found that the current system needs improvement. Its findings support calls in the literature for the development of a research ethics culture and a more complex understanding of the research ethics review process. In the interim, the review process would benefit from increased resources for REBs, as well as improved procedural and structural clarity and communication within and between boards.
Assembling identity

Publisher: name: No Publisher Supplied

description: I examine the social and historical context for the creation of object-portraits in American art in the decade following the First World War. Object-portraits are portraits in which the artist has replaced an image of the subject’s face or body with an object or a collection of objects. This phenomenon occurs specifically in the postwar moment when several actual and intellectual assault on selfhood – from the mechanization of the Great War, the effects of the Machine Age, developments in the field of psychology that challenged traditional notions of the self, and the burgeoning consumer culture and national advertising industry – caused artists to reassess the very nature of portraiture. What they were faced with was nothing less than the question of what it meant to be human in the modern age. Their answer to this problem, in the form of the object-portraits, redefined the boundaries between subject and object, human and thing. There are three main avenues of interdisciplinary inquiry this study has taken in order to determine how the social history of the self is written upon the object-portrait. First, I examine how contemporary shifts in the growing field of psychology impacted the understanding of identity in such a way as to de-center the self away from both the body and from the concept of a unified stable core. Object-portraits responded to this de-tabilizing of identity by searching for other means of visualizing the subject. Second, I analyze the history of technology and specifically of the body-machine metaphor to consider the various ways the object-portraits evince both a fascination with, and anxiety about, the machine in its myriad forms. And finally, I examine the contemporary advertising industry and consumer culture ideology, fueled by the application of psychology to commerce, and its manipulation of the subject/object relationship. I argue that the object-portraits, particularly the ones that appropriate an advertising aesthetic, participated in and commented on this marketed discourse. Therefore, the object-portraits examined here appear at the intersection of several histories. They anchor a variety of threads, from psychology to technology to advertising, and elucidate the construction of the self in the interwar period.

description: Fast IPv4 scanning has enabled researchers to answer a wealth of security and networking questions. Yet, despite widespread use, there has been little validation of the methodology’s accuracy, including whether a single scan provides sufficient coverage. In this paper, we analyze how scan origin affects the results of Internet-wide scans by completing three HTTP, HTTPS, and SSH scans from seven geographically and topologically diverse networks. We find that individual origins miss an average 1.6–8.4% of HTTP, 1.5–4.6% of HTTPS, and 8.3–18.2% of SSH hosts. We analyze why origins see different hosts, and show how permanent and temporary blocking, packet loss, geographic biases, and transient outages affect scan results. We discuss the implications for scanning and provide recommendations for future studies.

The Geometric Theta Correspondence for Hilbert Modular Surfaces

Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: In a series of papers we have been studying the geometric theta correspondence for non-compact arithmetic quotients of symmetric spaces associated to orthogonal groups. It is our overall goal to develop a general theory of geometric theta liftings in the context of the real differential geometry/topology of non-compact locally symmetric spaces of orthogonal and unitary groups which generalizes the theory of Kudla-Millson in the compact case. In this paper we study in detail the geometric theta lift for Hilbert modular surfaces. In particular, we will give a new proof and an extension (to all finite index subgroups of the Hilbert modular group) of the celebrated theorem of Hirzebruch and Zagier that the generating function for the intersection numbers of the Hirzebruch-Zagier cycles is a classical modular form of weight 2. In our approach we replace Hirzebuch's smooth complex analytic compactification $\tilde{X}$ of the Hilbert modular surface $X$ with the (real) Borel-Serre compactification $\bar{X}$. The various algebro-geometric quantities are then replaced by topological quantities associated to 4-manifolds with boundary. In particular, the "boundary contribution" in Hirzebruch-Zagier is replaced by sums of linking numbers of circles (the boundaries of the cycles) in the 3-manifolds of type Sol (torus bundle over a circle) which comprise the Borel-Serre boundary.

description: Elevated levels of the heavy metal lead are associated with various toxic effects which may also be due to interactions with lipid membranes. Bilayer and monolayer techniques were used to monitor lead interactions with biomimetic and polar lipid extracts. Anionic and zwitterionic lipids as well as saturated and monounsaturated fatty acids were compared. Permeabilization of model membranes by lead was assessed by quantifying fluorescent dye release, whereby leakage readily occurred upon Pb2+ incubation. Fluidity and phase transition changes were investigated by laurdan generalized polarization and dynamic light scattering. Electrostatic lipid targeting by lead induced membrane rigidification which varied with the negative charges within lipid structures. Lead effects on the lateral organization of monolayers were characterized by surface pressure- and surface potential – area isotherms and Brewster angle microscopy. Pb – induced domain formation depends on the number and localization of the phosphate groups on various phosphatidylinositols.
Parents' preferences for mixed-sex children

Publisher: name: No Publisher Supplied
Year: 2012

description: This dissertation uses nationally representative data from the National Survey of Families and Households toaddress the overarching question: ―For what reasons and with what consequences do people incorporate a preference for ̳at least one boy and one girl‘ into family formation ideals?‖In the first analysis, I evaluate three potential psychosocial frameworks motivating the mixed-sex ideal. Results support a ―separate spheres‖ ideology, through which parents may view the interests, traits, skills, and roles of boys and girls in families as very different. Second, results support a rational choice orientation, whereby achieving this goal maximizes having a variety of one‘s needs met in old age. Third,it may be motivated by its symbolic capital as a status marker, representing the image of a ―balanced,‖ ideal family. Based on beliefs about the non-substitutability of boys and girls, this ideal represents a form of gender inequality that persists in families. In the second analysis, I use discrete-time event history to associate individuals‘ statements about valuing a mixed-sex composition with odds of having a third child, accounting for within-couple differences on this preference.Couples with same-sex children did not have higher odds of a third birth than those with mixed-sex children. Furthermore, the degree to which couples valued having a mixed-sex composition did not matter more for those with same-sex children. Although couples with the strongest subscription to the mixed-sex ideal had significantly higher odds of a third birth than those with the lowest among couples with two boys, the effect of this pattern is too small to play a significant role in determining third births. In the third analysis, I examinewhether unfulfilled ideals for a mixed-sex composition are associated with negative psychological consequences among mothers. Results show that the sex composition of children was not associated with psychological well-being. Furthermore, women who valued a mixed-sex composition but did not obtain it did not report more depressive symptoms, poorer life satisfaction, or less satisfaction with family life than those who did not value the mixed-sex ideal. I discuss implications of findings for gender, families, psychological health, and ethical debates about sex-selection technologies.

Haar Wavelet based Block Autoregressive Flows for Trajectories

name: Schiele, Bernt
Publisher: name: CISPA

description: Prediction of trajectories such as that of pedestrians is crucial to the performance of autonomous agents. While previous works have leveraged conditional generative models like GANs and VAEs for learning the likely future trajectories, accurately modeling the dependency structure of these multimodal distributions, particularly over long time horizons remains challenging. Normalizing flow based generative models can model complex distributions admitting exact inference. These include variants with split coupling invertible transformations that are easier to parallelize compared to their autoregressive counterparts. To this end, we introduce a novel Haar wavelet based block autoregressive model leveraging split couplings, conditioned on coarse trajectories obtained from Haar wavelet based transformations at different levels of granularity. This yields an exact inference method that models trajectories at different spatio-temporal resolutions in a hierarchical manner. We illustrate the advantages of our approach for generating diverse and accurate trajectories on two real-world datasets - Stanford Drone and Intersection Drone.
Improving the learnability of mobile devices for older adults
Creators: name: Leung, Rock Anthony
Publisher: name: University of British Columbia
Year: 2011

description: Mobile computing devices, such as smart phones, offer benefits that may be especially valuable to older adults (age 65+). However older adults have been shown to have difficulty learning to use these devices, which is a barrier for technology adoption. The main goal of the research reported in this dissertation was to investigate three promising design approaches – increasing the interpretability of graphical icons, incorporating a multi-layered interface, and augmenting the mobile device’s display – to determine whether each can improve the learnability of mobile devices for older adults. We involved both older and younger adults in our studies to uncover benefits unique to older adults. In our investigation of graphical icons, we conducted an experiment to determine which icon characteristics affect initial icon interpretability for older adults. We found that icon interpretability can be improved for older adults by reducing the semantic distance between the objects depicted in the icon and the icon’s function, and by labelling icons. In our investigation of multi-layered interfaces, we prototyped a two-layer smart phone address book and conducted an experiment to assess its learnability over four learning phases. We found that the multi-layered interface, compared to a non-layered full-functionality control interface, provided greater benefits for older participants than for younger participants in terms of faster task completion times during initial learning, lower perceived interface complexity, and greater interface preference for learning. In our investigation of augmenting a mobile device display with a larger display to help older adults learn new devices, we conducted a comprehensive survey of older adults’ learning needs and preferences. Based on the survey findings, we designed and prototyped Help Kiosk, an augmented display system for helping older adults to learn to use a smart phone. An informal evaluation found preliminary evidence that Help Kiosk may be able to assist older adults in performing new mobile phone tasks. Through these three investigations, our research identified and validated design approaches that researchers and developers can use to improve the learnability of mobile devices for older adults, which should increase the chances of technology adoption.

description: We decide the Borel complexity of the conjugacy problem for automorphism groups of countable homogeneous digraphs. Many of the homogeneous digraphs, as well as several other homogeneous structures, have already been addressed in previous articles. In this article we complete the program, and establish a dichotomy theorem that this complexity is either the minimum or the maximum among relations which are classifiable by countable structures. We also discuss the possibility of extending our results beyond graphs to more general classes of countable homogeneous structures.

Subjects: Octagon quadrangle system, designs, decomposition.

description: An \emph{octagon quadrangle} is the graph consisting of a length $8$ cycle $(x_{1},x_{2},\dots,x_{8})$ and two chords, $\{x_{1},x_{4}\}$ and $\{x_{5},x_{8}\}$. An \emph{octagon quadrangle system} of order $v$ and index $\lambda$ is a pair $(X,\mathcal B)$, where $X$ is a finite set of $v$ vertices and $\mathcal B$ is a collection of octagon quadrangles (called blocks) which partition the edge set of $\lambda K_{v}$, with $X$ as vertex set. In this paper we determine completely the spectrum of octagon quadrangle systems for any index $\lambda$, with the only possible exception of $v=20$ for $\lambda=1$.

Subjects: Uniquely coloring; Edge coloring; Cubic

description: A graph $G$ is {\it uniquely k-edge-colorable} if the chromatic index of $G$ is $k$ and every two $k$-edge-colorings of $G$ produce the same partition of $E(G)$ into $k$ independent subsets.
For any $k\ne 3$, a uniquely $k$-edge-colorable graph $G$ is completely characterized;
$G\cong K_2$ if $k=1$, $G$ is a path or an even cycle if $k=2$,
and $G$ is a star $K_{1,k}$ if $k\geq 4$.
On the other hand, there are infinitely many uniquely 3-edge-colorable graphs, and hence, there are many conjectures for the characterization of uniquely 3-edge-colorable graphs.
In this paper, we introduce a new conjecture which connects conjectures of uniquely 3-edge-colorable planar graphs with those of uniquely 3-edge-colorable non-planar graphs.

description: The foothills of the Llanos Basin is an area of rough terrain and complex geology. Different post and pre-stack-time and depth migration algorithms were tested to improve seismic imaging, and reduce the effects of seismic anisotropy caused by dipping shales in the overburden. Raytracing modeling was a useful tool to identify shortcomings in the seismic acquisition parameters. Reprocessing of a seismic line using the new FRP anisotropic pre-stack depth migration from topography code gave excellent results in improving the seismic imaging in the subthrust areas. The APSDM let to new insights into the structural style of the area and gave an incentive to re-evaluate the exploration potential of the area. This thesis shows that the frontal thrust in the northern part of the Eastern Cordillera is an area of low angle thrust faults with the incipient formation of a triangle zone as opposed to previous workers who proposed inverted normal faults.

description: Deep learning enables impressive performance in image recognition using large-scale artificially-balanced datasets. However, real-world datasets exhibit highly class-imbalanced distributions, yielding two main challenges: relative imbalance amongst the classes and data scarcity for mediumshot or fewshot classes. In this work, we address the problem of long-tailed recognition wherein the training set is highly imbalanced and the test set is kept balanced. Differently from existing paradigms relying on data-resampling, cost-sensitive learning, online hard example mining, loss objective reshaping, and/or memory-based modeling, we propose an ensemble of class-balanced experts that combines the strength of diverse classifiers. Our ensemble of class-balanced experts reaches results close to state-of-the-art and an extended ensemble establishes a new state-of-the-art on two benchmarks for long-tailed recognition. We conduct extensive experiments to analyse the performance of the ensembles, and discover that in modern large-scale datasets, relative imbalance is a harder problem than data scarcity. The training and evaluation code is available at this https URL.
Semantic Bottlenecks: Quantifying and Improving Inspectability of Deep Representations

description: Today’s deep learning systems deliver high performance based on end-to-end training but are notoriously hard to inspect. We argue that there are at least two reasons making inspectability challenging: (i) representations are distributed across hundreds of channels and (ii) a unifying metric quantifying inspectability is lacking. In this paper, we address both issues by proposing Semantic Bottlenecks (SB), integrated into pretrained networks, to align channel outputs with individual visual concepts and introduce the model agnostic AUiC metric to measure the alignment. We present a case study on semantic segmentation to demonstrate that SBs improve the AUiC up to four-fold over regular network outputs. We explore two types of SB-layers in this work: while concept-supervised SB-layers (SSB) offer the greatest inspectability, we show that the second type, unsupervised SBs (USB), can match the SSBs by producing one-hot encodings. Importantly, for both SB types, we can recover state of the art segmentation performance despite a drastic dimensionality reduction from 1000s of non aligned channels to 10s of semantics-aligned channels that all downstream results are based on.

Year: 2011

description: Identifying information flow in emails is an important, yet challenging task. In this work we investigate several algorithms for identifying similar sentences in large email datasets, as well as an algorithm for reconstructing threads from unstructured emails. We present a detailed evaluation of each algorithm in terms of accuracy and time performance. We also investigate the usage of cloud computing in order to increase computational efficiency and make information discovery usable in real time.

Modelling the helical-flexo-electro-optic effect

description: The helical-flexo-electro-optic effect shows interesting in-plane electro-optic switching behaviour due to flexoelectric coupling with applied electric fields. Previous understanding of the behaviour has been generally based on an analytic approach which makes certain assumptions about the uniformity of the helical structure and the induced tilt angle under field application. Here we remove these assumptions and develop a perturbative approximation to describe the structure in more detail. We also use a numerical method to investigate the behaviour in regimes where the perturbative approach is inappropriate. The impact of variation in elastic constants and dielectric anisotropy is investigated. We find that dielectric behaviour in particular can lead to substantial differences between the tilt angle obtained here and those obtained using previous analytic models.

description: Given a 3-uniform hypergraph H(3), an H(3)-decomposition of the complete hypergraph K(3)_v is a collection of hypergraphs, all isomorphic to H(3), whose edge sets partition the edge set of K(3)_v. An H(3)-decomposition of K(3)_v is also called an H(3)-design and the hypergraphs of the partition are said to be the blocks. An H(3)-design is said to be balanced if the number of blocks containing any given vertex of K(3)_v is a constant. In this paper, we determine completely, without exceptions, the spectrum of balanced P(3)(1 5)-designs.

Heart rate variability biofeedback in the treatment of major depression

description: Major depressive disorder is the most common mood disorder and is one of the most burdensome and disabling diseases in the world. Prevailing approaches to treating depression have a number of significant limitations and drawbacks. Consequently, alternative and adjunctive treatments for depression are being increasingly explored. The role of autonomic nervous system functioning in the etiology of depression has been examined, and depression has been found to be associated with sympathetic predominance and parasympathetic impairment. This decreased parasympathetic modulation has been attributed to impaired activity of the vagus nerve, as indexed by attenuated heart rate variability (HRV) at the respiratory frequency. Areas of the brain that areinvolved in emotion regulation influence vagus nerve functioning. HRV biofeedback has been shown to be a modality through which individuals can learn to increase the amplitude of their HRV oscillations by breathing at specific rates. Through HRV biofeedback, the vagus nerve is thought to be stimulated in such a way that promotes autonomic balance and improved emotion regulation. Previous research suggests that HRV biofeedback may significantly reduce depression symptoms. The current study was a preliminary efficacy, randomized controlled trial that intended to follow-up an open label pilot study previously conducted by this lab, which found HRV biofeedback to be effective at significantly reducing depressive symptoms. The primary goal was to evaluate the efficacy of a HRV biofeedback protocol by comparing it to a sham control protocol with similar demand characteristics. The study also sought to evaluate the feasibility, tolerability and effectiveness of this placebo. Eleven participants were recruited from the UMDNJ-University Behavioral Health Care population and surrounding communities, and were randomized to a treatment group, receiving ten weeks of HRV biofeedback training and home practice, or a control group, receiving ten weeks of sham respiratory biofeedback training and home practice. Primary outcome measures were the HAMD and the BDI-II—assessed at baseline, week four, week seven, and week ten. Results indicated no significant differences in depression symptom improvement between groups, although significant main effects for time were observed for both groups (p
