Moratoria disciplinaria: estudios post-coloniales, feminismo de la tercera ola, y estudios de desarrollo

This paper explores some similarities between Feminism, especially intersectionality theory, Post-colonial studies, and Participatory Alternative Development. While the three fields deal with different subject matters they have commonalities such as methodology, historical development, and activism. The three fields have as their goal, not only the accumulation of knowledge but also to strive for transformation in the world. A general sympathy for the weak and the oppressed is also shared by the three fields and their empowerment is an important goal. Finally, the role of post-modernism as an intricately linked theoretical movement that has strengthened and weakened the three fields at one time or the other will be discussed.
Software engineering: anomalies in today's education and a prospectus for the future

“The only things that are new today are in the history that we have forgotten.” The purpose of this effort is to set up a beacon in front of a few of the pitfalls that exist and lie ahead in the advance of software engineering as the focus of computing for the late 80’s, 90’s and into the 21st century.
The Mathematical and Physical Papers of G. G. Stokes (1966)

In the recent renascence of continuum mechanics the name of Stokes is often mentioned, and some of his papers have been re-read again and again in the past twenty years. The new interest differs from that which originally greeted these same papers and has little to do with the specific discoveries ascribed to Stokes in the appreciations of his own day, the obituaries, and their epigones, the histories of physical science and the notes in textbooks. Rather, passages in which Stokes wrestled with first principles have been studied, line by line, for the method of inquiry they reveal.

Globalization of Law as Documented in the Law on International Sales of Goods

This paper, presented as part of the 2008-09 Willy Delva Lecture series at the University of Gent (Belgium) and published in Nieuw Internationaal Privaatrecht: Meer Europees, Meer Globaal 541 (J. Erauw & P. Taelman, eds.) (Kluwer, 2009), explores the extent to which the United Nations Convention on Contracts for the International Sales of Goods (“CISG”) is meeting the most fundamental challenge it confronts. The CISG adopts a particularly demanding vision of globalized law, but eschews the most potent means to achieve the uniform interpretation that vision requires. The CISG relies instead on an admonition that it be interpreted with regard for, inter alia, “its international character and the need to promote uniformity in its application....” Remarkable resources have appeared to aid in achieving this goal, creating a new information infrastructure and a new method of conducting legal research and practicing law. This paper analyzes three specific issues to test the success of courts and arbitral panels in employing these resources and achieving a uniform interpretation of the CISG: 1) the interpretation of choice of law clauses that designate the law of a Contracting State; 2) determining whether a seller must deliver goods that comply with domestic regulations of the buyer’s state; 3) incorporation of standards terms under the CISG, including adoption of the “rolling contract” theory under the Convention. Examining the treatment of these issues shows a mixed picture of success in implementing the uniformity mandate of the CISG, but one that leaves the author hopeful about the future of the Convention and its lofty ambitions.
Design of Short Reinforced Concrete Bridge Columns Under Vehicle Collision

This paper presents the behavior of reinforced concrete bridge columns subjected to vehicle collision. An extensive parametric study consisting of 13 parameters was conducted, examining the peak dynamic force and the equivalent static force (ESF) of a vehicle collision with reinforced concrete bridge columns. The ESF was calculated by using the Eurocode approach and the approach of the peak of the 25-ms moving average of the dynamic impact force. The ESFs from these two approaches were compared with the AASHTO load and resistance factor design ESF of 2,670 kN (600 kips). This ESF was found to be nonconservative for some cases and too conservative for others. The AASHTO load and resistance factor design ESF was nonconservative when the vehicle’s velocity exceeded 120 km/h (75 mph) and when the vehicle’s mass exceeded 16 tons (30 kips). This paper presents the first equation that calculates a design impact force, which is a function of the vehicle’s mass and velocity. The equation covers a wide range of veh...
Technological evaluation of gesture and speech interfaces for enabling dismounted soldier-robot dialogue

With increasing necessity for intuitive Soldier-robot communication in military operations and advancements in interactive technologies, autonomous robots have transitioned from assistance tools to functional and operational teammates able to service an array of military operations. Despite improvements in gesture and speech recognition technologies, their effectiveness in supporting Soldier-robot communication is still uncertain. The purpose of the present study was to evaluate the performance of gesture and speech interface technologies to facilitate Soldier-robot communication during a spatial-navigation task with an autonomous robot. Gesture and speech semantically based spatial-navigation commands leveraged existing lexicons for visual and verbal communication from the U.S Army field manual for visual signaling and a previously established Squad Level Vocabulary (SLV). Speech commands were recorded by a Lapel microphone and Microsoft Kinect, and classified by commercial off-the-shelf automatic speech recognition (ASR) software. Visual signals were captured and classified using a custom wireless gesture glove and software. Participants in the experiment commanded a robot to complete a simulated ISR mission in a scaled down urban scenario by delivering a sequence of gesture and speech commands, both individually and simultaneously, to the robot. Performance and reliability of gesture and speech hardware interfaces and recognition tools were analyzed and reported. Analysis of experimental results demonstrated the employed gesture technology has significant potential for enabling bidirectional Soldier-robot team dialogue based on the high classification accuracy and minimal training required to perform gesture commands.
Intercontinental Transport of Dust: Historical and Recent Observational Evidence

The scientific examination of the intercontinental dust transport has a long history, a vigorous present, and a promising future. Unlike the study of man-made pollution and biomass smoke, the fundamental causes of dust production, the long-range transport as well as the factors governing the removal processes of windblown dust were well established by about 1900. Much of the past century was devoted to the quantification of these processes using surface concentration monitors, aircraft sampling, and long-range transport modeling tools. By the 1990s, several new satellite sensors allowed a global-scale observation of the dynamic dust pattern. The aerosol climatologies derived from satellite data now highlight, in a semi-quantitative manner, the global distribution of dust sources. The dynamic daily aerosol data from several satellites, along with routine surface monitors now facilitates the quantitative documentation of individual intercontinental dust transport events from Sahara to Europe and the Americas, as well as from the Gobi desert to North America. In fact, the spectacular dust transport events visualized through the new satellite sensors along with the good performance of dust transport simulation and prediction models provide the most compelling evidence of intercontinental aerosol transport. Furthermore, the detection, tracking and the full explanation of these large dust events have catalyzed the emergence of ad hoc international internet-based virtual research communities. It is hoped that such collaboration over the next decades will yield a full quantification of intercontinental dust transport.
1982–4: A New Beginning or the Darkest Hour?

This chapter concentrates on a brief period in the history of Indo-Bangladesh relations, but it is a period which reveals more than has been acknowledged regarding the conduct and character of those relations. Analyses of relations between Bangladesh and India during the regime of Ziaur Rahman rarely vary from the common theme that the difficulties which have dogged relations between the two states have usually been generated wittingly, or unwittingly, by Bangladesh. This chapter examines the period from 1982 to 1984, providing evidence to show that Indo-Bangladesh relations underwent both subtle and obvious changes due to pressures emanating not just from within Bangladesh but from the interaction between a variety of internal and external forces.
New nutrients exert fundamental control on dissolved organic carbon accumulation in the surface Atlantic Ocean

The inventories of carbon residing in organic matter dissolved in the ocean [dissolved organic carbon (DOC)] and in the atmosphere as CO2 are of the same order of magnitude, such that small changes in the DOC pool could have important consequences in atmospheric carbon and thus climate. DOC in the global ocean is largely formed in the sunlit euphotic zone, but identifying predictable controls on that production is an important yet unrealized goal. Here, we use a testable and causative correlation between the net production of DOC and the consumption of new nutrients in the euphotic zone of the Atlantic Ocean. We demonstrate that new nutrients introduced to the euphotic zone by upwelling in divergence zones and by winter convective overturn of the water column, and the primary production associated with those nutrients, are the ultimate driver of DOC distributions across the Atlantic basins. As new nutrient input will change with a changing climate, the role of DOC in the ocean's biological pump should likewise be impacted.
Promoting Engaged Scholars: Matching Tenure Policy and Scholarly Practice

This article explores what an uneven embrace of community engagement means for faculty as they apply for tenure and promotion. It closely examines how three faculty members (including the author) from different departments framed and discussed their engaged scholarly contributions in the presence or absence of departmental guidelines on engaged scholarship. Their experiences and success reveal the influence of departmental context on decisions to include engagement in faculty evaluation criteria and the importance of finding strategies to mitigate the absence or underdevelopment of guidelines.
Diversity Theory and Practice

This chapter will describe different theories and practices related to diversity and how those theories and practices have shaped the need for DQ. There are lots of theories that concern race such as critical race theory; however, there are few that deal directly with diversity. This is part of the confusion in the workplace caused by the introduction of the term “diversity.” When most individuals hear the term “diversity,” they quickly deduce that it means race, and maybe it should, but it does not mean race in many organizations.
Mediated proton transport through Nafion 117 membranes imbibed with varying concentrations of aqueous VOSO 4 (VO 2+ ) and NH 4 VO 3 (VO 2 + ) in 2 M H 2 SO 4

Abstract We performed an extensive study on Nafion 117 membrane imbibed with various concentrations of aqueous ammonium metavanadate (NH4VO3), and vanadyl sulfate (VOSO4), in 2 M H2SO4 over the temperature range of 20–100 °C, using 1H NMR and AC Impedance spectroscopies. The objective was to determine the effect of the tetravalent (VO2+) and pentavalent (VO2+) vanadium ions on the proton transport of Nafion 117.1H NMR chemical shift and linewidth data show greater short-range proton transport for the VO2+ imbibed membranes compared with the VO2+. However, the local environments seem to differ in that while the data for VO2+ imbibed membranes seem to follow more the trends observed for water hydrated Nafion 117, those for the VO2+ followed the trend of its aqueous bulk vanadium solvents, indicating that viscosity plays a larger role for the VO2+ imbibed membranes compared to the VO2+.
Timing characterizations of device and CPU-like circuit to ensure process reliability

Existing methodology and stress conditions are ideal for process benchmarking but might not be sufficient under fierce competition between advanced technology development approaches. In this paper, the importance of timing delay characterization in both device and circuit level is demonstrated and emphasized. Due to the difficulties of having accurate aging model for product level simulation during early stage of process development, silicon to simulation (S2S) correlation should be established in circuit level. Experiments in this study cover from discrete device, ring oscillator (RO) and a circuit block from ARM CPU. Based on the extensive results, the characterization of timing margin is highly recommended. So, early warnings of circuit reliability risk can be obtained to save major detours during technology development.
Ultimate CMOS density limits: measured source drain resistance in ultra small devices

The dependence of the extrinsic component of the series resistance of CMOS devices on the size of the source/drain areas has been explored experimentally. Trench isolated depletion mode n- and p-channel MOSFETs with silicided source/drain areas from 1.7*2 mu m/sup 2/ to 0.2*0.3 mu m/sup 2/ have been fabricated using electron beam lithography. A sheet resistance of 3-5 Omega / Square Operator and a contact resistivity of p/sub c/=3-6*10/sup -7/ Omega -cm/sup -2/ have been obtained for the TiSi/sub 2/ contact technology. The measured extrinsic series resistance is observed to increase rapidly for source/drain sizes below the contact transfer length of 0.6-0.8 mu m and to become larger than the intrinsic series resistance component. Based on these data, the upper limit for the CMOS current drive capability and the lower limit for propagation delay as a function of source/drain size are established. >
Resistance to Melanaphis sacchari (Hemiptera: Aphididae) in Forage and Grain Sorghums

The sugarcane aphid, Melanaphis sacchari (Zehntner), has established itself as a perennial pest of grain and forage sorghums in the United States since the summer of 2013. We conducted traditional plant resistance studies that determine tolerance, antibiosis, and antixenosis in 32 sorghum genotypes when challenged with sugarcane aphids. The genotypes included one exotic plant introduction and 31 seed and pollinator parental lines that are used to produce grain, sudangrass, and forage sorghum hybrids. One seed parent (B11055) and one grain pollinator parent (R13219) expressed significant degrees of tolerance, antibiosis, and antixenosis and were top performers in all three resistance type experiments. An additional group of seed parents (B13045 and B1057) and grain pollinator parents (R11159, R13422, and RTx2908) and the plant introduction (PI 550610) resulted in an intermediate range of phenotypic resistance (i.e., 4.0 < 6.0) indicative of antibiosis from reduced fecundity, increased intrinsic rate of increase, and increased generation times. The forms of resistance expressed in these lines, especially B11055 and R13219, have great potential in breeding programs that can be integrated into useable forms of resistant sorghums.
Patients with Blunt Traumatic Brain Injury: A Role for Computed Tomography Angiography of the Head to Evaluate Nontraumatic Causes?

Background In the setting of trauma, the cause of intracranial hemorrhage (ICH) is frequently attributed to the physical, traumatic event. Caution should still be directed toward nontraumatic (or spontaneous) causes responsible for the trauma, such as hypertension, cerebral amyloid angiopathy, aneurysms, vascular malformation, and hemorrhagic infarcts. The role for immediate computed tomography angiography remains controversial to evaluate for nontraumatic causes. Methods A systematic review of the available literature in the Medline PubMed database. Results In the available literature, only 12 patients with traumatic brain injury underwent computed tomography angiography of the head that either showed a vascular malformation and/or altered clinical management because of concerns of a vascular malformation. The ICH in 11 patients was attributed to rupture of a cerebral aneurysm; the other patient received a diagnostic angiogram that was negative. Conclusions ICH in patients with traumatic brain injury seems to be vastly associated with the traumatic event. Only rare cases have been attributed to aneurysmal rupture. None has been associated with arteriovenous malformation. Nevertheless, clinical vigilance remains reasonable, especially in younger patients and those with hemorrhage within the subarachnoid cisterns or sylvian fissure.
Stem cell genes in androgen-independent prostate cancer.

Despite recent advances in the detection and treatment of early stage prostate cancer, there remains little effective therapy for patients with locally advanced and/or metastatic disease. Although the majority of patients with advanced disease respond initially to androgen ablation therapy, most go on to develop androgen-independent tumors that are inevitably fatal. Therefore, understanding the mechanisms by which a hormone-sensitive tumor escapes hormonal control is critical to the development of effective therapeutic modalities. The study of the differentiation pathways of normal and abnormal prostate growth has led to the development of a stem cell model for prostate cancer [1–3]. Recent work discussed in this commentary suggests that prostate tumors resist apoptosis and proliferate by adopting features of normal prostatic stem/progenitor cells. Basal cells, the putative stem/progenitor cells of the prostate, possess the phenotype of androgen-independence as do most advanced prostate cancers. Therefore, the study of basal cells may prove critical to understanding prostate carcinogenesis and to the development of novel strategies for preventing and managing prostate cancer.
Exact boundary controllability of a Schrödinger equation with an internal point mass

We consider a linear system composed of two Schrodinger equations of equal length connected by a point mass interface condition. We show that the system is exactly controllable with either a Dirichlet or Neumann boundary control at one end. The novelty of this paper concerns the nature of the space of exact controllability. We find that in the case of Dirichlet control, the space of exact controllability is symmetric in terms of regularity with respect to the point mass. This is in contrast to the case of Neumann control where the exact controllability space is asymmetric with respect to the point mass in the sense that the regularity is one degree higher on the side of the point mass opposite the control.
Zustand und Schicksal des schwarzen Ghettos am Ende des Jahrhunderts

Zwanzig Jahre nach den Aufstanden, die Mitte der 1960er Jahre in den schwarzen Stadtteilen Amerikas – von Watts bis Detroit – Feuer der Wut haben auflodern lassen, ist das Ghetto an die vorderste Front der nationalen Debatte zuruckgekehrt. Doch dieses Mal ist der spektakulare, gegen die weise Herrschaft gerichtete Aufruhr, der die afroamerikanischen Bezirke der nordamerikanischen Grosstadte zerrissen hatte, einer „unterschwelligen Randale“ (Curtis 1985) aus endemischer Kriminalitat, kollektiver Armut, und innerem sozialen Verfall gewichen. Bilder von weisen Polizisten in den Spatnachrichten, die die staatliche Gewalt auf friedliche schwarze Demonstrierende niederschmettern, welche die Anerkennung ihrer elementaren Rechte einfordern, sind von grausigen Berichten uber Drive-by-Shootings, „Wohlfahrtsabhangigkeit“ und die „Teenager-Schwangerschaften-Krise“ in den schwarzen amerikanischen Innenstadten abgelost worden.

Then, this article discusses management processes of social media analytics for enterprises. An illustration of social media analytics is provided with real-world consumer review data. Finally, four challenges are discussed.
Predictors of Urology Resident Surgical Skills, Clinical Communication Skills, Common Sense and In-Service Scores

Abstract Objective To evaluate predictors of urology resident surgical skills, clinical-communication skills, common sense, and in-service scores. Methods We reviewed the Mayo Clinic experience with 49 urology residents who graduated between 2006 and 2016. Residents were independently scored 1-10 based on surgical skills, clinical-communication skills, and common sense by the Program Director and Associate Program Director. Discrepant scoring by >2 was resolved by the former Program Director. Associations of features from the medical student application with an excellent score (defined as 8-10) and in-service scores were evaluated with logistic and linear regression. Results Discrepant scoring >2 was noted in only 1, 0, and 1 resident for surgical skills, clinical-communication skills, and common sense, respectively. The mean scores for surgical skills, clinical-communication skills, and common sense were 6.4, 7.1, and 7.0, respectively, and an excellent score was noted in 16 (33%), 19 (39%), and 24 (49%) residents, respectively. The strongest feature associated with an excellent score in each category was honors in all core clinical clerkships (p Conclusions An honors grade in all clinical clerkships during medical school is the strongest feature predictive of excellent surgical skills, clinical-communication skills, and common sense among urology residents. While USMLE scores are associated with in-service scores, they do not predict for clinical skills.
Multichannel key exchange

As the world is becoming more and more connected, managing security of the network system is becoming more difficult. One of the ways to ensure security is by encrypting the data and in order to do so, the encryption key needs to be exchanged between the devices trying to communicate with each other. The key exchange that happens today use only a single communication channel, in this paper author tries to secure key exchange process and designs a key exchange technique using multiple channels.
Quantitative assessment of surface functionality effects on microglial uptake and retention of PAMAM dendrimers

Dendrimers are a promising class of polymeric nanoparticles for delivery of therapeutics and diagnostics. Polyamidoamine (PAMAM) dendrimers have shown significant efficacy in many animal models, with performance dependent on surface functionalities. Understanding the effects of end groups on biological interactions is critical for rational design of dendrimer-mediated therapies. In this study, we quantify the cellular trafficking kinetics (endocytosis and exocytosis) of generation 4 neutral (D4-OH), cationic (D4-NH2), anionic (D3.5-COOH), and generation 6 neutral (D6-OH) PAMAM dendrimers to investigate the nanoscale effects of surface functionality and size on cellular interactions. Resting and LPS-activated microglia were studied due to their central roles in dendrimer therapies for central nervous system disorders. D4-OH exhibits greater cellular uptake and lower retention than the larger D6-OH. D4-OH and D3.5-COOH exhibit similar trafficking kinetics, while D4-NH2 exhibits significant membrane interactions, resulting in faster cell association but lower internalization. Cationic charge may also enhance vesicular escape for greater cellular retention and preferential partitioning to nuclei. LPS activation further improves uptake of dendrimers, with smaller and cationic dendrimers experiencing the greatest increases in uptake compared to resting microglia. These studies have implications for the dependence of trafficking pathway on dendrimer properties and inform the design of dendrimer constructs tailored to specific therapeutic needs. Cationic dendrimers are ideal for delivering genetic materials to nuclei, but toxicity may be a limiting factor. Smaller, neutral dendrimers are best suited for delivering high levels of therapeutics in acute neuroinflammation, while larger or cationic dendrimers provide robust retention for sustained release of therapeutics in longer-term diseases.
Modelling microvascular pathology.

A physiologically relevant microvasculature-on-a-chip device enables the study of microvascular pathology associated with inflammation and haematological diseases.
Automorphisms and Asymptotic Numbers of One-Factorizations

In this chapter we explore a few properties of automorphisms and automorphism groups of one-factorizations. We then proceed to prove that the number of isomorphism classes of one-factorizations of K 2n tends to infinity as n does. This result, which forms a nice extension of the result of Theorem 11.4, was proven independently in [11] and [107]; the proofs are quite similar, but [107] also includes another proof using quasigroups. Basically we shall follow [11].
Distal Gastrectomy with D2 Nodal Dissection, Roux-en-Y Reconstruction for Cancer

Subtotal gastrectomy with D2 nodal dissection is indicated for gastric cancer limited to the distal portion of the stomach that can be resected with adequate margin without taking down the short gastric vessels. This chapter lists the indication, essential steps, common technical variations, and complications of the procedure. A detailed operative dictation template is included.
Interventricular septal motion during preexcitation and normal conduction in Wolff-Parkinson-White syndrome: Echocardiographic and electrophysiologic correlation☆

Abstract Interventricular septal motion was studied by echocardiogram in 20 consecutive patients with documented Wolff-Parkinson-White (WPW) syndrome before and during electrophysiologic evaluation using His bundle recordings and pacing techniques. Characteristic abnormal interventricular septal motion was seen in 8 of 11 patients with type B WPW syndrome (groups I and II). All eight patients had electrocardiographic patterns consistent with an anomalous pathway located in the anterior right ventricular wall (group I). In five of these eight patients normalization of the QRS complex for one or more beats was accomplished and produced normalization of the septal motion in four; whereas in the fifth patient, who had an underlying atrial septal defect, the abnormal septal motion remained abnormal. All nine patients with type A WPW syndrome (groups III to V) had normal septal motion both during total preexcitation and during normalization of the QRS complex. The normalization of the abnormal interventricular septal motion with normalization of the QRS complex in type B WPW syndrome strongly suggests that the abnormal motion is related to an abnormal sequence of ventricular depolarization during preexcitation. Furthermore, persistent abnormal septal motion after normalization of the QRS complex suggests that other factors such as right ventricular volume overload may be responsible. Likewise, when abnormal septal motion occurs in the presence of type A WPW syndrome, an explanation other than preexcitation must be sought.
Your Patient With Melanoma: Staging, Prognosis, and Treatment

Melanoma, a cancer of melanocytes, pigment-producing cells in the skin, is the most serious form of skin cancer. Its incidence is increasing rapidly and reaching epidemic proportions. When detected early, it is considered curable, but when detected at later stages it is arguably one of the most lethal malignancies and is the cause of more years of lost life than any other cancer except leukemia. Because most cutaneous melanomas are visible, however, melanoma in general is a cancer highly amenable to early detection. Surgery is standard treatment for localized melanoma. There is no standard therapy for advanced-stage melanoma. Metastatic melanoma disseminates widely and it frequently involves sites that are not commonly affected in other cancers, such as the gastrointestinal tract and skin. The median survival time for patients with metastatic melanoma is less than 1 year. Despite these grim statistics, long-term survival occurs occasionally. This article will review diagnosis, staging, and treatment for malignant melanoma and will discuss the nursing role in the care of patients with melanoma.
Social Risk Factors Impact Hospital Readmission and Outpatient Appointment Adherence for Children with Congenital Heart Disease.

Objective To examine the relations of individual and cumulative social risk factors to hospitalization outcomes and adherence to outpatient cardiology appointments within the first 2 years of life for congenital heart disease survivors. Study design Data were extracted for 219 patients who underwent infant cardiac surgery with cardiopulmonary bypass. Cumulative social risk was dichotomized into high social risk (≥2 risk factors; n = 103) versus low social risk (≤1 risk factor; n = 116). The risk of morbidity by procedure was assigned from 1 to 5 (Society of Thoracic Surgeons and European Association for Cardio-Thoracic Surgery Morbidity Scores and Categories). Two-way ANOVAs examined the effects of social risk and morbidity risk on length of first surgical hospitalization, number of readmissions and readmission days, subsequent cardiac surgical interventions, and adherence to outpatient cardiology appointments. Results An interaction between social risk and morbidity risk was identified for number of readmission days, F(4, 209) = 3.07, P = .02, η2 = .06. Pairwise comparisons demonstrated that, among those patients with the lowest risk of morbidity by procedure (morbidity scores of 1 and 2), patients at high social risk had more readmission days than patients at low social risk (morbidity score 1: 16.63 ± 34.41 days vs 3.02 ± 7.13 days; morbidity score 2: 27.68 ± 52.11 days vs 2.20 ± 4.43 days). High social risk also predicted significantly worse adherence to cardiology appointments. Conclusions Cumulative social risk impacts readmission days for patients with congenital heart disease with a low risk of morbidity by procedure. Social risk assessment can identify families who may benefit from social/behavioral interventions to optimize discharge readiness, congenital heart disease home management, and long-term outcomes.
Total system error analysis of UAV-CRP technology for monitoring transportation infrastructure assets

Abstract Infrastructure forms the backbone of a nation's economy, and there is a growing demand for a technology that offers quick, safe, and reliable infrastructure performance monitoring data, which would lead to proactive maintenance or repairs of the infrastructure to ensure its quality performance as per the original design. The increase in the applications of unmanned aerial vehicles (UAVs) or drones for such monitoring purposes have been propelled by advancements in aerial vehicle platforms and image-analyses software. Evaluating UAVs for high-quality infrastructure-distress data monitoring has been a major focus for this research. Photogrammetry is the science of measuring distances from two or multiple images of an object and close range photogrammetry (CRP) can be accomplished by using an optical camera mounted on a UAV platform and taking the images of the infrastructure object. This technology, hereafter termed as UAV-CRP technology, utilizes UAVs coupled with high quality camera lens and a global navigation satellite system (GNSS) device to collect high quality data with fewer ground control points (GCPs). The various pieces of equipment need to have their aerial technology compatibility tested in different environmental conditions and evaluate the imagery that is used for image analyses and interpretations. A comprehensive set of calibration checks were executed using the total system comprising of UAV and accessories to evaluate the imagery quality level of transportation and geotechnical infrastructure data. All the checks performed ensured that the data obtained from the UAV-CRP technology meets the quality requirements for infrastructure data. A case study of pavement infrastructure data was provided to validate the high accuracy UAV-CRP data obtained following the guidelines developed in this paper.
Longitudinal Maternal Vitamin D Status During Pregnancy Is Associated With Neonatal Anthropometric Measures

Findings on maternal 25-hydroxyvitamin D (25[OH]D) and neonatal anthropometry are inconsistent, and may at least be partly due to variations in gestational week (GW) of 25(OH)D measurement and the lack of longitudinal 25(OH)D measurements across gestation. The aim of the current study was to examine the associations of longitudinal measures of maternal 25(OH)D and neonatal anthropometry at birth. This study included 321 mother⁻offspring pairs enrolled in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Fetal Growth Studies⁻Singletons. This study was a prospective cohort design without supplementation and without data on dietary supplementation. Nevertheless, measurement of plasma 25(OH)D reflects vitamin D from different sources, including supplementation. Maternal concentrations of total 25(OH)D were measured at 10⁻14, 15⁻26, 23⁻31, and 33⁻39 GW and categorized as 75 nmol/L. Generalized linear models were used to examine associations of 25(OH)D at each time-point with neonate birthweight z-score, length, and sum of skinfolds at birth. At 10⁻14 GW, 16.8% and 49.2% of women had 25(OH)D <50 nmol/L and between 50⁻75 nmol/L, respectively. The association of maternal 25(OH)D with neonatal anthropometry differed by GW and women's prepregnancy BMI (normal (<25.0 kg/m²), overweight/obese (25.0⁻44.9 kg/m²)). All analyses were stratified by prepregnancy BMI status. Among women with an overweight/obese BMI, 25(OH)D <50 nmol/L at 10⁻14 GW was associated with lower birthweight z-score (0.56; 95% CI: -0.99, -0.13) and length (-1.56 cm; 95% CI: -3.07, -0.06), and at 23⁻31 GW was associated with shorter length (-2.77 cm; 95% CI: -13.38, -4.98) and lower sum of skinfolds (-9.18 mm; 95% CI: -13.38, -4.98). Among women with a normal BMI, 25(OH)D <50 nmol/L at 10⁻14 GW was associated with lower sum of skinfolds (-2.64 mm; 95% CI: -5.03, -0.24), at 23⁻31 GW was associated with larger birthweight z-scores (0.64; 95% CI: 0.03, 1.25), and at 33-39 GW with both higher birthweight z-score (1.22; 95% CI: 0.71, 1.73) and longer length (1.94 cm; 95% CI: 0.37, 3.52). Maternal 25(OH)D status during pregnancy was associated with neonatal anthropometric measures, and the associations were specific to GW of 25(OH)D measurement and prepregnancy BMI.
Political Property Rights and Entangled Political Economy

I contribute to the theory of entangled political economy by showing how entanglement can be characterized in terms of political property rights. A political property right grants its holder a share of decision-making power in a specific context, as well as specifies to whom the costs and benefits from those decisions accrue. Because entangled political economy focuses on the complex relationships that exist between market and political enterprises, theorizing about these relationships as exchanges of political property rights can give us meaningful information about what entanglement is, when it exists, and how it can be expected to develop. I briefly survey the theory of political property rights, show how political property rights within a broader entanglement perspective helps understand constitutions, and discuss several applications of political property rights that can advance entangled political economy scholarship.
Using a Virtual Manipulative Intervention Package to Support Maintenance in Teaching Subtraction with Regrouping to Students with Developmental Disabilities.

To live independently, it is critical that students with disabilities maintain the basic mathematical skills they have acquired so they may apply these skills in daily life. To support maintenance of mathematical skills among students with developmental disabilities, the researchers used a multiple probe across participants design to examine the effectiveness of the VRA instructional sequence with fading support in teaching subtraction with regrouping to four students with developmental disabilities. A functional relation was found between the VRA instructional sequence with fading support and students’ accuracy in solving the problems. Students also maintained the skill up to 6 weeks after the intervention.
TFAP2C regulates carbonic anhydrase XII in human breast cancer.

The expression of carbonic anhydrase XII (CA12) is associated with the expression of estrogen receptor alpha (ERα) in breast cancer and is linked to a good prognosis with a lower risk of metastasis. Transcription Factor Activator Protein 2γ (TFAP2C, AP-2γ) governs luminal breast cancer phenotype through direct and indirect regulation of ERα and ERα-associated genes, GATA3, FOXA1, EGFR, CDH1, DSP, KRT7, FBP1, MYB, RET, KRT8, MUC1, and ERBB2-genes which are responsible for the luminal signature in breast cancer. Herein, utilizing chromatin immunoprecipitation and direct sequencing (ChIP-seq), we show that CA12 is regulated by AP-2γ through binding with its promoter region in luminal breast cancer cell lines and indirectly through a distal estrogen-responsive region in ERα-positive cell lines by upregulation of ERα. CA12 is transcriptionally silenced in basal breast cancer cell lines through histone deacetylation and CpG methylation of the promoter region and can be re-activated with Trichostatin A (histone deacetylase inhibitor) and/or 5-aza-dC (an inhibitor of DNA methylation). Strong concordance in co-expression of CA12 and ESR1 (R2 = 0.1128, p = 0486) and TFAP2C (R2 = 0.1823, p = 0.0105) was found using a panel of primary breast tumor samples (n = 35), supporting a synergetic role of AP-2γ and ERα in activation of CA12. Our results highlight the essential role of AP-2γ in maintaining the luminal breast cancer phenotype and provide evidence that epigenetic mechanisms silence luminal gene expression in the basal phenotype. Additional studies to decipher mechanisms that drive epigenetic silencing of AP-2γ target genes are a critical area for further research.
Recurrent Slipping Rib Syndrome: Initial Experience with Vertical Rib Stabilization Using Bioabsorbable Plating.

Background: Slipping rib syndrome (SRS) is an often underdiagnosed cause of lower chest wall and abdominal pain. The diagnosis of SRS is established by physical examination with or without dynamic ultrasound. The pain can be debilitating and surgical excision of the nonattached, subluxing cartilages is curative for most patients, but frustratingly, up to a quarter of patients have transient or limited relief and require reoperation. Some of these patients were found to have subluxation of the remaining bony ribs, suggesting that excision of rib cartilage alone may not be curative in a subset of patients. Materials and Methods: A retrospective review was performed of 3 patients with recurrent slipping rib pain and hypermobile bony ribs on reoperation. In an effort to stabilize the hypermobile ribs, vertical bioabsorbable plating across their ribs was performed. The plates secure the ribs apart from each other, preventing the movement of ribs against each other and therefore the pain. Results: All patients tolerated the procedure well. Mean length of stay was 2.6 days. Mean follow-up is 7 months and all report significant improvement in pain. Conclusions: Rib plating allows stabilization of hypermobile ribs, while preserving the patient's anatomical rib cage, and is a safe treatment for recurrent pain after the initial procedure. This is a novel approach in patients with recurrent slipping rib symptoms.
The Influence of Relationship Dynamics and Sexual Agreements on Perceived Partner Support and Benefit of PrEP Use Among Same-Sex Male Couples in the U.S.

Use of Pre-exposure prophylaxis (PrEP) for HIV prevention by men who have sex with men (MSM) may be impacted by relationship dynamics. We assessed perceived partner support of PrEP use and benefit of PrEP by relationship characteristics among male couples. Baseline data from a randomized control trial of video-based HIV counseling and testing among male couples in the U.S. were used in adjusted multilevel regression models to assess individual and dyadic characteristics. Among 659 participants, 73.3% thought their partner would be supportive of their PrEP use; 26.7% reported their partner would not support PrEP use, which was significantly associated with intimate partner violence (IPV) (p = 0.008). Most (57.7%) did not believe PrEP would be beneficial to them or their partner. Couples with a sexual agreement allowing outside partners were significantly associated with higher perceived support of partners for PrEP (p < 0.001) and benefit of PrEP use (p < 0.001). Perceived partner support of PrEP was high but perceived benefit of PrEP was low, both shaped by relationship dynamics that highlight the need for tailored dyadic interventions. The association between perceived PrEP support and IPV points to the need to integrate relationship contexts in HIV prevention programs.

What Works in Mindfulness Interventions for Medically Unexplained Symptoms? A Systematic Review.

Background/Purpose: Mindfulness-based interventions (MBIs) have been used in medically unexplained symptoms (MUS). This systematic review describes the literature investigating the general effect of MBIs on MUS and identifies the effects of specific MBIs on specific MUS conditions. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines (PRISMA) and the modified Oxford Quality Scoring System (Jadad score) were applied to the review, yielding an initial 1,556 articles. The search engines included PubMed, ScienceDirect, Web of Science, Scopus, EMBASE, and PsychINFO using the search terms: mindfulness, or mediations, or mindful or MBCT or MBSR and medically unexplained symptoms or MUS or Fibromyalgia or FMS. A total of 24 articles were included in the final systematic review. Results/Conclusions: MBIs showed large effects on: symptom severity (d = 0.82), pain intensity (d = 0.79), depression (d = 0.62), and anxiety (d = 0.67). A manualized MBI that applies the four fundamental elements present in all types of interventions were critical to efficacy. These elements were psycho-education sessions specific to better understand the medical symptoms, the practice of awareness, the nonjudgmental observance of the experience in the moment, and the compassion to ones' self. The effectiveness of different mindfulness interventions necessitates giving attention to improve the gaps that were identified related to home-based practice monitoring, competency training of mindfulness teachers, and sound psychometric properties to measure the mindfulness practice.
Slurries for Copper Damascene Patterning: Similarities and Differences

Two first-step copper damascene slurries and one commercial second-step slurry are characterized in terms of their intrinsic properties and CMP performance. A prototype first-step slurry with high static etch rate (∼150 nm/min) yielded higher dishing in the copper lines (∼200 nm in 100 μm lines) compared to a commercial first-step slurry with negligible static etch rate. In both the cases, dishing in copper lines is observed to be a strong function of line width and radial position on the wafer. High static etch rate of the prototype slurry is believed to be responsible for the high dishing. Non-selective second-step polishing removes the liner layer while maintaining planarity.
Artificial Intelligence and Smart Universities

“Smart University” is the practical application of smart intelligence in the field of education. The adaption of IoT (Internet of Things) and smart technologies has created new learning platforms and emphasizes the value of learning. Smart campuses are equipped with smart class rooms and smart infrastructures. They are staffed by smart individuals who implement smart strategies. The results will enhance advanced learning outcomes and facilitate acquisition of information. This chapter will examine the transformation which occurs in traditional universities/colleges where artificial intelligence is taking place, thus reshaping the future of current learning models.
Postmortem submersion interval (PMSI) estimation from the microbiome of sus scrofa bone in a freshwater lake.

While many studies have developed microbial succession-based models for the prediction of postmortem interval (PMI) in terrestrial systems, similar well-replicated long-term decomposition studies are lacking for aquatic systems. Therefore, this study sought to identify temporal changes in bacterial community structure associated with porcine skeletal remains (n = 198) for an extended period in a fresh water lake. Every ca. 250 ADD, one cage, containing 5 ribs and 5 scapulae, was removed from the lake for a total of nineteen collections. Water was also sampled at each interval. Variable region 4 (V4) of 16S rDNA was amplified and sequenced for all collected samples using Illumina MiSeq FGx Sequencing platform; resulting data were analyzed with the mothur (v1.39.5) and R (v3.6.0). Bacterial communities associated with ribs differed significantly from those associated with scapulae. This difference was mainly attributed to Clostridia, Holophagae, and Spirochaete relative abundances. For each bone type, α-diversity increased with ADD; similarly, β-diversity bacterial community structure changed significantly with ADD and were explained using environmental parameters and inferred functional pathways. Models developed using 24 rib and 34 scapula family-level taxa allowed the prediction of PMSI with root mean square error of 522.97 ADD (~57 days) and 333.8 ADD (~37 days), respectively.
