Toward an Understanding of Ligand Selectivity in Nanocluster Synthesis

We performed scalar relativistic density functional theory (DFT) calculations using the projector augmented wave scheme (PAW) to examine the reactivity and selectivity of diphosphine ligands LM, with the formula PH2(CH2)MPH2 (spacer M = 3, 5), toward small-sized cationic Aun (n = 7–11) nanoclusters. By isolating the ligand-induced contribution to the stability condition, we show that such interaction selectively stabilizes the cationic Au11 cluster. Furthermore, we find that L5 with the longer spacer is more capable than L3 of relieving the strain imposed on the spacer by bidentate binding to gold clusters, which have relatively small Au–Au bond lengths. Thus L5 can interact effectively with gold clusters of various sizes, but L3 can do so only with a selected few. This result demonstrates the size-selecting power of L3 toward small gold clusters such as Au113+. To further test the validity of our results we have extended the calculation to a larger cluster, Au13, and also considered the case of a ligand ...
The Narrow-Band System La1-xSrxTiO3

Magnetic, transport, and structural data on polycrystalline samples of the system La1-xSrxTiO3, 0 ≤ x ≤ 0.8, show an abrupt, but apparently smooth, transition from p-type polaronic conduction in a canted-spin antiferromagnetic system for x ≤ 0.04 to metallic, mass-enhanced Pauli paramagnetic behavior for x ≥ 0.1 with evidence for a spin glass and a discontinuous drop in TN in the transition range. We interpret these results as a manifestation of the coexistence of two distinguishable electronic domains within a single crystallographic phase as a result of cooperative displacements of the oxygen atoms.
Integration of Program Outputs: Development of a Pest Management System

Although the current effort in the program to develop a management system for the Douglas-fir tussock moth is a new venture, it is built on a solid foundation of previous research by a few key scientists at the Pacific Northwest Forest and Range Experiment Station. Their long-range studies and technical expertise have been critically important in this expanded effort.
Comparison of 2 Methods of Hexavalent Chrome Determinations in Drinking Water

[Objective]To establish the sensitive and rapid determination of hexavalent chrome in drinking water.[Methods]In the weak acid solution,micro-chromium(VI) in the water and diphenylcarbazide reacted with anion active agent and sodium dodecyl sulfate into purplish red ternary iron compound which could be extracted by chloroform and quantified at wavelength 550nm.[Results]The calibration curve showed good linearity in the range of 1 ~ 40 μg/L. The minimum detectable concentration was 0.001 mg/L. The RSD was 1.1%～1.4% and the recovery rate was 95%～110%.The sensitivity of this method was 3.8 times that of diphenylcarbazide spectrophotometry of GB/T 5750.6-2006 "Standard testing methods for drinking water o Metal Index".[Conclusion]This method is sensitive and accurate that can meet the requirements of standard testing methods for drinking water.
A Hybrid Fuzzy-Firefly Approach for Rule-Based Classification

Pattern classification algorithms have been applied in data mining and signal processing to extract the knowledge from data in a wide range of applications. The Fuzzy inference systems have successfully been used to extract rules in rule-based applications. In this paper, a novel hybrid methodology using: (i) fuzzy logic (in form of if-then rules) and (ii) a bio-inspired optimization technique (firefly algorithm) is proposed to improve performance and accuracy of classification task. Experiments are done using nine standard data sets in UCI machine learning repository. The results show that overall the accuracy and performance of our classification are better or very competitive compared to others reported in literature.
Reusability study of fiber optic based protein C biosensor.

Protein C (PC) is a vitamin K-dependent plasma zymogen produced in the liver. It is present at a concentration of 4.0μg/ml in normal plasma and, importantly, acts as both a potent anticoagulant and antithrombotic. The major activator of PC is thrombin that is formed during blood coagulation. Activation occurs on the surface of endothelial cells by means of a complex with thrombin and thrombomodulin. The PC exhibits its anti-coagulating ability by cleaving activated co-factors V and VIII into inactive fragments. This proteolytic cleavage requires, among other things, protein S and Ca++. The PC exhibits its antithrombotic nature by stimulating fibrinolysis through the indirect activation of plasminogen (Esmon et al., 1995, Reltsma, 1997).
Dynamic Imaging Reveals Coordinate Effects of Cyclic Stretch and Substrate Stiffness on Endothelial Integrity

We describe an equibiaxial cell stretcher and hybrid, elastic membrane platform designed for dynamic imaging of cells on substrates with physiological stiffness undergoing cyclic stretch. Studies enabled by this device revealed that both substrate stiffness and cyclic stretch coordinately protect pulmonary endothelial monolayers against thrombin-induced disruption. The fluorescence imaging possible with the designed hybrid membranes further revealed similarities and differences in actin and cell dynamics during monolayer recovery. The improved live-cell imaging capabilities of this platform, when used in conjunction with fluorescent probes, will have broad applications for investigations of the impact of biochemical stimuli and mechanotransduction mechanisms on mechanically perturbed tissues.
Exciter and Transceiver Design

This chapter discusses the performance requirements of an exciter, its component parts are assembled in an architecture that meets the requirements and its necessary functions. A transceiver may be defined as an exciter and receiver combined in one functional unit.
The Role of Linguistic Explanation in the Acquisition of Japanese Imperfective - teiru

Previous studies on the L2 acquisition of -teiru in Japanese have revealed that the resultative meaning of -teiru is learned later than its progressive meaning, as predicted by the Aspect Hypothesis (Shirai and Kurono, Language Learning, 48, 245–279, 1998). It has also been found that learners have problems with the resultative meaning of -teiru when there is L1—L2 crosslinguistic discrepancy in lexical aspect (Nishi, Verb learning and the acquisition of aspect: Rethinking the universality of lexical aspect and the significance of L1 transfer. Unpublished Ph.D. dissertation, Cornell University, Ithaca, 2008). While researchers have uncovered the universal tendency of the developmental process of -teiru, it is not clear what promotes the learning of more difficult (or less prototypical or more marked) meanings of -teiru, and to what extent instruction affects the learning. It is also a question of whether the lexical aspect of verbs in L2 is learnable. As an attempt to address these issues, this study investigated the role of explicit grammar instruction on the learning of the resultative meaning of -teiru, by teaching L2 learners of Japanese the notion of lexical aspect, and how the aspectual meaning of -teiru is determined by lexical aspect. The results showed a positive effect of explicit form-focused instruction for the beginner group, but not for the intermediate group. The findings suggest that explicit linguistic explanation may facilitate the learning of Japanese imperfective -teiru, at least in the early stages of learning.
Sleep-Mode Voltage Scaling: Enabling SRAM Data Retention at Ultra-Low Power in Embedded Microcontrollers

In heavily duty-cycled embedded systems, the energy consumed by the microcontroller in idle mode is often the bottleneck for battery lifetime. Existing solutions address this problem by placing the microcontroller in a low-power (sleep) mode when idle and preserving application state either by retaining the data in situ in Static Random Access Memory (SRAM) or by checkpointing it to Flash. However, both of these approaches have notable drawbacks. In situ data retention requires the SRAM to remain powered in sleep mode, while checkpointing to Flash involves significant energy and time overheads. This article proposes a new ultra-low-power sleep mode for microcontrollers that overcomes the limitations of both of these approaches. Our technique, Hypnos, is based on the key observation that the on-chip SRAM in a microcontroller exhibits 100% data retention even at a much lower supply voltage (as much as 10× lower) than the typical operating voltage of the microcontroller. Hypnos exploits this observation by performing extreme voltage scaling when the microcontroller is in sleep mode. We implement and evaluate Hypnos for the TI MSP430G2452 microcontroller and show that the Microcontroller (MCU) draws only 26nA in the proposed sleep mode, which is 4× lower than a baseline sleep mode that preserves SRAM contents. Further, to reduce the overheads associated with performing the voltage scaling, we propose the use of an energy harvesting source for providing the scaled supply voltage and demonstrate (using a light sensing photodiode) that the current consumption in the proposed sleep mode can be reduced to 1nA, which is 100× lower than the current consumption in the baseline low-power mode. We also show that the decrease in sleep-mode power consumption translates to a reduction in application-level energy consumption by as much as 6.45×. By decreasing the average power consumption to such minuscule levels, Hypnos takes a significant step forward in making perpetual systems a reality through the use of energy harvesting.
Important Lessons Learned From Nearly a Half-Century of Orthopedic Practice.

“Those who cannot remember the past are condemned to repeat it” [1]. The famous quote from Hispanic American philosopher George Santayana reminds us of the critical importance of constantly reflecting on the most important lessons garnered from both our own personal experiences and those of our peers. In 49 years of academic orthopedic practice, I have frequently reflected on the most important lessons I have learned, and to which, in addition to hard work and perhaps simple luck, I attribute much of my success
New methods for the preparation of nanoscale nickel phosphide catalysts for heteroatom removal reactions

The removal of heteroatom impurities (S, N, O) from fossil fuel and biomass feedstocks is a critical step in the production of clean-burning transportation fuels. Nickel phosphide (Ni2P) has emerged as a leading candidate material on which to base a new class of catalysts to compete with the long established Ni–Mo and Co–Mo sulfides for hydrotreating of crude oil feedstocks. A recent assessment by researchers at ExxonMobil suggested that a Ni2P catalyst having a 3 nm particle size could compete with a state-of-the-art Co–Mo/Al2O3 catalyst for the hydrodesulfurization (HDS) of a straight-run gas oil feed. This article reviews recent advances in the low-temperature preparation of highly-active, nanoscale Ni2P catalysts.
A Driven Random Field System: CDW Dynamics

Pinned charge density waves can be regarded as a model for the study of the dynamics of random systems. The nonlinear and frequency dependent conductivity of several materials is discussed, with particular emphasis on the nonlinear ac effects and higher harmonic generation, on the remanent polarization and on the critical properties as the threshold field is approached from below.
Fundamental Examination of Multiple Potential Passive Component Technologies for Future Power Electronics

Efficient and compact high-power high-frequency passive energy storage components are required for miniaturization of power converters and remain a challenging obstacle in power electronics. In this paper, multiple energy storage mechanisms are analyzed on an order-of-magnitude basis to identify potential alternatives for conventional passive components, especially magnetics, which have frequency-dependent power losses. The high energy density of mechanical storage methods provides an attractive alternative to the widely used LC resonance. Piezoelectric transduction is explored, and the performance of a piezoelectric resonator is compared to that of an LC resonator in terms of efficiency and power handling capabilities in a resonant switched-capacitor-type circuit. The analysis provides a basis for exploring potential passive energy storage component technologies and comparing their performance limits with those of electromagnetic passive components. The analysis shows that both electromagnetic and mechanical resonance, in the ideal scenarios, can offer much better performance than do passive component technologies in use today. A prototype resonator is built with off-the-shelf C0G capacitors to confirm the low loss and high power predicted by the model. The resulting resonator has an effective resistance of 2.76 $\text{m}{\Omega }$ at 2.70 MHz in 1 ${\text{cm}^{3}}$ volume and can handle 7.42 kW within the rated temperature.
Summary of Session J: The Dosimetry Handbook

The two reports in this session provide fascinating insight into the past, present, and future of the Radiofrequency Radiation Dosimetry Handbook Mr. John C. Mitchell presents a historical perspective on the origins of the handbook. As stated by Mr. Mitchell, the handbook was essential to “assist biological scientist to: (1) design better experiments, (2) more correctly interpret existing biological effects studies, and (3) extrapolate from animal studies performed under various laboratory conditions to likely human response under realistic (real world) RFR exposures.” Development of the four editions of the dosimetry handbook was clearly a passion of several individuals working as a coherent group. Two important qualities of the handbook were that it was written at a level that was easy to comprehend by the novice researcher and the data withstood the test-of-time. Specific absorption rate (SAR) values predicted by more current computer hardware and software are similar to those presented in the dosimetry handbook. Testimonial to the importance of the Radiofrequency Radiation Dosimetry Handbook is that more than 2000 hardcopies have been distributed and it is one of the most referenced publications in bioelectromagnetic research.
Router-Level Topologies of Autonomous Systems

In order to understand the Internet topology, it is important to analyze the underlying networks’ characteristics. Internet is enabled by independently operating Autonomous Systems (ASes) that collaborate to provide end-to-end communication. In this paper, we investigate the network characteristics of backbone ASes that provide transit connectivity. We collect router-level probe data sets from all of the public Internet topology measurement platforms and obtain network topologies of the backbone ASes. We then analyze the network characteristics of each AS and perform an in-depth analysis of the high ranked ASes. Analyzing two snapshots, we observe disassortative network topologies in the majority of AS topologies independent of their network size. Also, most of the top-ranked ASes have a densely connected core and exhibit power-law degree distributions.
Revealing Bound Exciton Physics in Strongly Interacting Band Insulators

The field of excitonics has gained increased attention in the last years, due to the unique properties that excitons manifest in the conversion and transport of energy. Key to these developments is the ability to exploit the physics of these collective charge excitations in materials that are easily fabricated and widely available. Particular interest is being devoted to organic semiconductors, transition metal dichalcogenides and wide-bandgap oxides, following the discovery of bound and resonant excitons in these classes of materials.
Pain Management in the Pediatric Palliative Care Population

Purpose The purpose of this integrative review was to identify, review, synthesize, and analyze the current literature related to pain management in the pediatric palliative care population from infancy through adolescence. Methods The literature was searched for the terms palliative, pediatric, and pain in PubMed, PsycINFO, Cumulative Index to Nursing and Allied HeALTH LITERATUre (CINAHL) Complete, and Google Scholar. The search was limited to papers in English that had been published from January 1, 2005, to December 31, 2016. Results These searches resulted in 918 articles, of which 29 met inclusion criteria. These 29 articles were reviewed and reported. Four broad themes emerged: patient and family experience, pain assessment, pharmacological pain management, and nonpharmaceutical interventions. Conclusions Gaps in current research have been identified, such as investigating pediatric pain scales for the palliative care population and new complementary and alternative medical therapy and other interventions. More research is needed to bring innovative pain management interventions to the attention of pediatric caregivers. Clinical relevance A better understanding of current research on pain in the pediatric palliative care population can improve patient care and lead to better research in this specialty field.
Perforated cecal adenocarcinoma presenting as a thigh abscess

Complicated colorectal carcinoma has several symptoms, the most common being bleeding and obstruction. Occasionally it will cause perforation, which carries a worse prognosis. We report a case of perforated adenocarcinoma of the cecum that presented as an abscess of the thigh. We also present a review of the literature on this subject.
Papillary Glioneuronal Tumor

A benign (WHO grade I), relatively circumscribed, biphasic cerebral neoplasm occurring predominantly in the temporal lobe and most commonly affecting young adults. No population-based epidemiologic data are available to date. Papillary glioneuronal tumor (PGNT) was initially described as “pseudopapillary ganglioglioneurocytoma” or “pseudopapillary neurocytoma with glial differentiation.” Established as a distinct clinicopathologic entity in 1998 by Komori et al. Regarded as a variant of ganglioglioma in the 2000 WHO classification of central nervous system tumors. Recently added as a new entity in the 2007 WHO classification.
From Conceptual Models to Agent-based Simulations: Why and How

The core problem we address in this paper is how to take a declarative conceptual representation of a complex system and produce an agent-based simulation of that model. In particular, we describe a computational technique that takes Structure-Behavior-Function models of complex systems and simulates the behavior of the modeled system in NetLogo, an agent-based programming and simulation environment. This technique has been implemented in an interactive learning environment to promote complex systems learning among middle school students.
Stoichiometry of triple-sieve tRNA editing complex ensures fidelity of aminoacyl-tRNA formation

Aminoacyl-tRNA synthetases catalyze the attachment of cognate amino acids onto tRNAs. To avoid mistranslation, editing mechanisms evolved to maintain tRNA aminoacylation fidelity. For instance, while rejecting the majority of non-cognate amino acids via discrimination in the synthetic active site, prolyl-tRNA synthetase (ProRS) misactivates and mischarges Ala and Cys, which are similar in size to cognate Pro. Ala-tRNAPro is specifically hydrolyzed by the editing domain of ProRS in cis, while YbaK, a free-standing editing domain, clears Cys-tRNAPro in trans. ProXp-ala is another editing domain that clears Ala-tRNAPro in trans. YbaK does not appear to possess tRNA specificity, readily deacylating Cys-tRNACysin vitro. We hypothesize that YbaK binds to ProRS to gain specificity for Cys-tRNAPro and avoid deacylation of Cys-tRNACys in the cell. Here, in vivo evidence for ProRS-YbaK interaction was obtained using a split-green fluorescent protein assay. Analytical ultracentrifugation and native mass spectrometry were used to investigate binary and ternary complex formation between ProRS, YbaK, and tRNAPro. Our combined results support the hypothesis that the specificity of YbaK toward Cys-tRNAPro is determined by the formation of a three-component complex with ProRS and tRNAPro and establish the stoichiometry of a 'triple-sieve' editing complex for the first time.

Chapter Four – STOCHASTIC PROCESSES

Publisher Summary A family of random variables {X(t) t є T} is called a stochastic process. For each t є T, where T is the index set of the process, X(t) is a random variable. An element t of T is usually referred to as a time parameter and t is often referred to as time. The state space of the process is the set of all possible values that the random variables X(t) can assume. Each of these values is called a state of the process. Stochastic processes are classified in a number of ways, such as by the index set and by the state space. This chapter reviews stochastic processes with emphasis on those that have immediate application to computer science problems. It considers the Poisson process, which is fundamental to computer science and to all the areas of applied probability. The birth-and-death process is a key element in queueing theory. The chapter discusses Markov chains. These are used in queueing theory and in many other computer science applications. A Markov process is called a Markov chain if its state space is discrete. The chapter presents a classification of Markov processes.
Long-term follow-up and evaluation of the treatment effect of self-administered family therapy of patients with chronic Keshan disease

Objective To analyze and evaluate the long-term effects of self-administered family therapy(family therapy) interventions on patients with chronic Keshan disease, and provide guidance for improving patient survival and quality of life. Methods A retrospective analysis method was used to collect case data of patients with chronic Keshan disease who participated in family therapy intervention projects for 2 consecutive years or more in Zoucheng City, Shandong Province from 2008 to 2018. According to the general conditions, clinical signs, the changes of electrocardiogram, cardiac color ultrasound, cardiac function grading, the therapeutic effect and prognosis were evaluated. Results A total of 74 patients with chronic Keshan disease were studied, including 33 males and 41 females, with an average age of 47.63 years old. At the last survey of family therapy, the total effective rate was 78.38% (58/74). Fisher′s exact probability test showed that environmental factors had a significant effect on the efficacy of patients with chronic Keshan disease (P 0.05). Before and after the family therapy, the distribution of cardiothoracic ratio and cardiac function grading were significantly different, and the ventricular high voltage condition was significantly improved (P < 0.05); the patient′s cardiac function grading before family therapy and the effect of the last family therapy had a significant effect on the final outcomes (P < 0.05). Conclusions The long-term continuous family therapy intervention has a significant effect on the curative effect of patients with chronic Keshan disease, and can improve the prognosis even better. Family therapy is a scientific intervention that requires long-term adherence. Key words: Family therapy; Keshan disease; Self-administered; Efficacy evaluation
A Cybersecurity Terminarch: Use It Before We Lose It

Why can't we send encrypted email (secure, private correspondence that even our mail providers can't read)? Why do our health-care providers require us to use secure portals to correspond with us instead of directly emailing us? Why are messaging apps the only way to send encrypted messages directly to friends, and why can't we send private messages without agreeing to using a single platform (WhatsApp, Signal, and so on)? Our cybersecurity tools have not evolved to offer these services, but why?
Mental Illness and Gun Violence

Nearly 200,000 Americans are injured every year from firearms. One of the most common topics of discussion and research in this area is mental health and suicidal behavior, since most of the fatalities are due to firearm suicides. Suicide screening and preventive measures are key strategies to improve these grim statistics.
The X-Ray Timing Explorer

The capabilities of the X-ray Timing Explorer (XTE) are described with particular attention paid to current scientific problems it will address from galactic neutron star systems to active galactic nuclei. It features a low-background continuous 2–200 keV response with large apertures (a 0.63-m2 proportional counter array and a 0.16-m2 dual rocking Nal/Csl scintillation array). Rapid response (in hours) to temporal phenomena, e.g. transients, is obtained by virtue of a scanning all-sky monitor and rapid maneuverability. XTE will carry out detailed energy-resolved studies of phenomena close to neutron stars (e.g. QPO’s) because of its sub-millisecond timing (to 10 μs), its high telemetry rates (to 256 kb/s), and the high throughput of its data system (to ≳ 2 × 105 c s-1).
Assessment of coated cladding impact on large-break LOCA with TRACE-DAKOTA

Abstract Since 2011, the U.S. Department of Energy has launched new research and development (R&D) programs for developing new accident tolerant fuels (ATFs). These new fuel concepts are expected to bring several advancements in terms of plant safety. However, development, licensing, as well as deployment of ATF require a substantial investment among fuel vendors, operating utilities, and regulatory authorities. For ATF to be economically feasible, credited safety benefits may be necessary to provide an economic incentive for transition of nuclear power plants from Zr/UO2-based fuel technologies to ATFs. As a result, it is essential to evaluate the economic viability of ATF by conducting a comprehensive safety benefits study informed by R&D and demonstration studies. In the present work, based on the best estimate plus uncertainty methodology, sensitivity analysis and uncertainty quantification for key safety quantities under LB-LOCA are performed for the Peach Bottom boiling water reactor (BWR) with GE14 nuclear fuel design adopting the ATF concepts. A coupled TRACE-DAKOTA analysis framework is adopted to perform the uncertainty quantification. Based on the computational results and obtained statistics, the coping time increase, fuel performance improvement as well as the most dominating phenomena during the accident for Cr-coated cladding are investigated in detail. The results obtained are useful for subsequent plant PRA study and support a move to more modernized performance-based regulatory requirements to realize plant economic benefits.
REDECA: A Novel Framework to Review Artificial Intelligence and Its Applications in Occupational Safety and Health.

Introduction: The field of artificial intelligence (AI) is rapidly expanding, with many applications seen routinely in health care, industry, and education, and increasingly in workplaces. Although there is growing evidence of applications of AI in workplaces across all industries to simplify and/or automate tasks there is a limited understanding of the role that AI contributes in addressing occupational safety and health (OSH) concerns. Methods: This paper introduces a new framework called Risk Evolution, Detection, Evaluation, and Control of Accidents (REDECA) that highlights the role that AI plays in the anticipation and control of exposure risks in a worker’s immediate environment. Two hundred and sixty AI papers across five sectors (oil and gas, mining, transportation, construction, and agriculture) were reviewed using the REDECA framework to highlight current applications and gaps in OSH and AI fields. Results: The REDECA framework highlighted the unique attributes and research focus of each of the five industrial sectors. The majority of evidence of AI in OSH research within the oil/gas and transportation sectors focused on the development of sensors to detect hazardous situations. In construction the focus was on the use of sensors to detect incidents. The research in the agriculture sector focused on sensors and actuators that removed workers from hazardous conditions. Application of the REDECA framework highlighted AI/OSH strengths and opportunities in various industries and potential areas for collaboration. Conclusions: As AI applications across industries continue to increase, further exploration of the benefits and challenges of AI applications in OSH is needed to optimally protect worker health, safety and well-being.
177 LU-DOTATATE radioligand therapy in gastroeneteropancreaticneuroendocrine tumors: a single center retrospective analysis

1451 Introduction: Neuroendocrine tumors (NETs) are heterogeneous tumors arising from either the gastroenteropancreatic (GEP) tract or the bronchopulmonary tree. Somatostatin analogs (SSAs) are the first line therapy for somatostatin receptor (SSTR) avid, well-differentiated, inoperable and metastatic NETs. Multiple treatment options are available once progression of disease occur. These include kinase inhibitors, mTOR inhibitors, chemotherapy, and the recently FDA approved radioligand therapy with 177Lu-DOTATATE (RLT) targeting somatostatin-receptors present on NETs. We present a retrospective analysis of clinical patients treated with PRRT in our clinic. Methods: From July 2016 to December 2019, 78 patients with GEP NETs were treated with RLT in our clinic (M/F: 43/35; mean age 62.93 ± 11.34 years). The mean injected activity per cycle was 195.17±5.62 mCi. Fifty-three patients (67.95%) completed 4 PRRT cycles, 7 (8.97%) underwent 3 cycles, 9 (11.54%) underwent 2 cycles, and 9 (11.54%) underwent 1 cycle. Tumor response evaluation post-PRRT was obtained using RECIST 1.1 criteria from anatomic cross-sectional imaging (CT or MRI) or functional imaging (68Ga-DOTATATE PET/CT or Octreoscan SPECT/CT). Post-RLT tumor response was evaluated only for patients who completed all 4 cycles of RLT at time of the analysis. Grade, differentiation and Ki-67 were correlated with treatment response. Results: Of the 53 patients who completed all 4 PRRT cycles, 27 lacked follow-up imaging. Time between PRRT cycle 1 and post treatment image was 275.46 +-53.25 days. Post-PRRT tumor response was calculated on a total of 26 patients (M/F: 16/10; mean age 66,00 ±11 years). Of this patient population, 22 patients (84.62%) demonstrated overall progression-free stable disease, and 4 patients (15.38%) showed disease progression. Of the latter group, 3 patients had a new lesion on follow-up imaging, and one patient had two target lesions which increased in size on follow up imaging. Conclusions: In our retrospective analysis of post-approval clinically treated GEP-NET patients RLT was able to achieve disease control in most of the patients. Lower/higher Grade/Ki-67/differentiation were correlated with better disease control.
The Impact of Data Distribution on Fairness and Robustness in Federated Learning

Federated Learning (FL) is a distributed machine learning protocol that allows a set of agents to collaboratively train a model without sharing their datasets. This makes FL particularly suitable for settings where data privacy is desired. However, it has been observed that the performance of FL is closely related to the similarity of the local data distributions of agents. Particularly, as the data distributions of agents differ, the accuracy of the trained models drop. In this work, we look at how variations in local data distributions affect the fairness and the robustness properties of the trained models in addition to the accuracy. Our experimental results indicate that, the trained models exhibit higher bias, and become more susceptible to attacks as local data distributions differ. Importantly, the degradation in the fairness, and robustness can be much more severe than the accuracy. Therefore, we reveal that small variations that have little impact on the accuracy could still be important if the trained model is to be deployed in a fairness/security critical context.
A rodent anchored hybrid enrichment probe set for a range of phylogenetic utility: From order to species.

Rodents are the largest order of mammals and contain several model organisms important to scientific research in a variety of fields, yet no large set of genomic markers have been designed for this group to date, hindering evolutionary studies into relationships of the group as a whole. Here we present a genomic probe set designed and optimized for rodents with a protocol that is easy to replicate with little laboratory investment. This design utilizes an anchored hybrid enrichment approach specifically targeting rodents to generate longer loci with a higher substitution rate than existing vertebrate probes to provide utility at various taxonomic levels. Using a test set of rodents from all five suborders, we successfully obtained alignments for 416 of the 418 target loci with an average of 1379 bp per locus and a total alignment of more than half a million base pairs. This genomic data set performed well in all phylogenetic analyses, especially in recent phylogenetic splits, with ample parsimony-informative sites within genera and even within species, showing more than four times as many single nucleotide polymorphisms per locus than a recent vertebrate ultraconserved elements study. Additional support is provided in resolving deeper clades in Rodentia. By providing this probe design, we hope that more laboratories can easily generate data for answering questions in rodents from species delimitation to understanding relationships among families in rapid radiations.
Analysis of Capacitive Coupling within Microelectrode Array

Capacitive coupling within high-density microelectrode arrays can degrade neural recording signal or disperse neural stimulation current. Material deterioration in a chronically implanted neural stimulation/recording system can cause such an undesired effect. We present a simple method with an iterative algorithm to quantify the cross-coupling capacitance, in-situ.
Prospects for Progress: The TRIPS Agreement and Developing Countries After the DOHA Conference

Intellectual property rights (IPRs) have long been the subject of contentious debate between developed and developing countries. While providing an incentive to invest in and develop new technologies, IPRs also vastly increase the cost of these new technologies to developing countries. Despite disagreement on the proper role for IPRs in the global economy, IPRs became a major element in the 1994 Uruguay Round of the General Agreement on Tariffs and Trade (GATT), which established the World Trade Organization (WTO). Effective on January 1, 1995, the Trade-Related Aspects of Intellectual Property Agreement (TRIPS Agreement) formally linked compliance with minimum protection standards with international trade. This linkage directly affects technology flows to, and the course of development in, developing countries. While the Fourth Ministerial Conference at Doha, Qatar on November 9-13, 2001 integrated the concerns of developing countries more fully than previous Ministerial Conferences, the issue of technology acquisition and development in light of the increasing technology gap between developed and developing countries was overlooked.
Linear arithmetic code and its application in fault-tolerant systolic array

Fault-tolerant systolic arrays for matrix-vector multiplication are proposed. A novel method called the linear arithmetic code technique is introduced which can detect and correct n errors caused by a single faulty module in a linear systolic array. This approach can be extended to other matrix operations. >
North Carolina Assessment of Risk (NCAR): Reliability and Predictive Validity with Juvenile Offenders

Abstract Actuarial risk assessment instruments are used increasingly in juvenile justice to classify youths according to their risk of recidivism. The purpose of this article is to describe the results of two studies of one instrument: the North Carolina Assessment of Risk (NCAR). In the first study, the inter-rater reliability of the risk assessment instrument was estimated with a sample of 175 court counselors who rated videotaped vignettes of juvenile offenders. In the second study, predictive validity was assessed prospectively by following a statewide sample of 464 delinquent youths for 12 months. Findings indicate that the risk assessment instrument increases reliability as compared to clinical judgment. Moreover, risk scores are correlated significantly with rearrest. However, analyses also show that relationships between risk scores and recidivism vary for subgroups based on gender and race/ethnicity. Though challenges remain in improving the accuracy of risk assessment, the findings suggest that ...
Negotiating Social Identity

Publisher Summary The ongoing processes of identity negotiations that form the source of the social identity of an individual form the main area of focus in this chapter. The effects that a change of circumstances have on the daily behavior and reference group of a person are, in particular, presented to the readers. The social identification framework, in which individuals are considered representatives of social categories, is adopted for the study. The discourse starts off with a discussion about the social parameters of identification. The dynamics of social identification have been reviewed closely. The importance of contexts and settings in influencing the choices of a person is also highlighted in the chapter. Two different identity negotiation strategies—identity negation and identity enhancement—are presented, and the importance of striking a proper balance between them is also made apparent. Identity negotiation can result from social stigmatization, and this has been given special importance. The perception of threat acts as a bridge between stigmatization and the selection of an identity negotiation strategy. It is imperative to understand the social norms and contexts that lead to the very circumstances of negotiating stigmatized identity.
MO‐E‐17A‐12: Direct Realization of the CT Dose to Phantom: Energy to Heat Conversion in Polyethylene Using Calorimetry

Purpose: To develop a primary reference standard for absorbed dose to phantom for medical CT dosimetry. CT dosimetry relies on the implementation of the CTDI standard based on air kerma. We are taking a step toward an absorbed dose to water standard by first investigating the dose in a solid phantom. By directly measuring the heat converted from the incident radiation, the absorbed dose in the phantom at a point can be assessed with primary methods without relying on indirect conversions. Methods: The calorimeter contains two small thermistors embedded in a removable PE “core” inserted into the cylindrical HDPE phantom. A core made with polystyrene (PS) was also tested because of its purportedly negligible heat defect. Measurements were made using the two cores and with a calibrated ionization chamber in a CT beam. The air chamber values were converted to the dose to medium using appropriate stopping-power ratios from the literature, and then compared to the thermal data. Results: The PS core data yielded a dose of 1.3 times (4-run average, 3% std. dev.) higher than the converted chamber value, whereas the PE core data were inexplicably higher. The possible systematic errors include 1) excess heat from the thermistors, 2)more » in PE the exothermic chemical reactions, 3) uncertainties of the specific heat capacities of the materials, 4) thermal drift, and 5) theoretical conversion of chamber values. Monte Carlo simulations and finite element heat transfer calculations were performed to address some of these issues. The general validity was assessed in a 6 MV photon beam with an entirely different calibration scheme. Conclusion: This study demonstrates the feasibility but also revealed the difficulty in developing a new primary reference standard for absorbed dose to material for CT. Additional experimental and theoretical work is planned to achieve our goal.« less
Current Trends in Childhood Obesity Research

Childhood obesity is a global health issue. To identify research trends and gaps of childhood obesity research, we reviewed MEDLINE publications from January 2011 to May 2012 and qualitatively analyzed the major domains and themes of research focus. Major domains are: measurements, obesity correlates, prevention interventions, treatment interventions, and policy issues. Key advances and innovations are highlighted within each domain. Emerging areas include the advancement of measurement methodologies that simultaneously capture individual and contextual information across time, analysis of policy problems, and the development of multilevel, community interventions. However, few effective and sustainable interventions are exemplified; some strategies are promising. Recommendations for future research includes the adoption of a systems approach that integrates individual, environmental, and policy change, the scale up and diffusion of innovations, studies of intended and unintended policy impacts, and the design and testing of effective social marketing strategies.
Role of Purkinje Fibers in Post-Infarction Ventricular Tachycardia

Objectives The objective of this study was to assess the role of Purkinje fibers in monomorphic, post-infarction ventricular tachycardia (VT). Background Ventricular fibrillation and polymorphic VT in the setting of acute myocardial infarction (MI) may be triggered by ectopy arising from Purkinje fibers. Methods From among a group of 81 consecutive patients with post-infarction monomorphic VT referred for catheter ablation, 9 patients were identified in whom the clinical VT had a QRS duration ≤145 ms. Mapping was performed focusing on areas with Purkinje potentials. Results A total of 11 VTs with a QRS duration ≤145 ms were induced and mapped in the 9 patients; 9 of the 11 VTs had a right bundle branch block/left-axis morphology that mimicked left posterior fascicular VT. The mean VT cycle length was 402 ± 82 ms. Eight of 9 patients had a history of inferior MI involving the left ventricular septum. One patient had an anterior wall MI with septal involvement. Mapping during VT demonstrated re-entry involving the inferior left ventricular wall. In each of the VTs, a Purkinje potential was present at the exit site of the VT re-entry circuit. Single radiofrequency catheter ablation lesions were successful in eliminating these VTs in all patients. Conclusions The Purkinje system may be part of the re-entry circuit in patients with post-infarction monomorphic VT, resulting in a type of VT with a relatively narrow QRS complex that mimics fascicular VT.
Bilateral Patching in Retinal Detachment: Fluid Mechanics and Retinal "Settling"

Purpose. When a patient suffers a retinal detachment and surgery is delayed, it is known clinically that bilaterally patching the patient may allow the retina to partially reattach or “settle.” Although this procedure has been performed since the 1860s, there is still debate as to how such a maneuver facilitates the reattachment of the retina.
MR angiography of the renal arteries

During, the past decade. MRA has evolved from an cxperimental technique into the modality of choice for the noninvasive evaluation of renovascular disease. The recent widespread application of MRA for these indications has been driven primarily by the advent of 3D contrast-enhanced MRA. which provides a fast, reliable technique for imaging large vascular territories and generates images, after postprocessing, similar in appearance to digital subtraction angiography. The cross-sectional volumetric nature of contrast-enhanced MRA affords some advantages over conventional catheter angiography. Although 3D contrast-enhanced MRA forms the backbone of vascular MR studies, several adjunctive sequences are employed to maximize the diagnostic yield of the examination. For example. flow-dependant imaging is used to complement the morphologic images of contrast-enhanced MRA by providing hemodynamic information. As such, MRA is unique among noninvasive imaging modalities in that it offers a comprehensive evaluation of anatomy and function. The availability and reliability of MRA extend renal artery screening to a wider spectrum of patients. Current applications of renal MRA range from detection of renal artery stenosis to evaluation for renal transplant donors.

Curriculum for Clinical Practice

A masters' level curriculum for clinical practice with the elderly is presented which highlights four areas: successful aging, theories of adult psychological development, practice with families and practice with groups. These areas have been abstracted from a fuller curriculum which includes practice with depressed and demented elders and their families, crosscultural practice, death and dying, interdisciplinary practice. The areas elaborated here are newer, hold special appeal for clinical students, and emerge from demographic trends.
