A CMOS transceiver with internal PA and digital pre-distortion for WLAN 802.11a/b/g/n Applications

A 2.4/5GHz Fully-Integrated Transceiver is implemented in 65nm CMOS technology. To alleviate the cost of external front-end components, the G-mode RF transmit/receive (T/R) switch and a power-efficient linear CMOS PA are fully integrated on-chip. On the other hand, for better performance, only the A-mode PA is integrated on-chip while the external T/R switch is used. It shows 5dB and 5.5dB NF in the G-mode and A-mode receivers respectively. Also, the transmitter delivers an average power of 18dBm OFDM (64QAM, 54MBPS) signal with EVM of -28dB for G-mode application and 16dBm OFDM (64QAM, 54MBPS) signal with EVM of −28dB for A-mode application after digital pre-distortion.
Tails of optimal transport plans for regularly varying probability measures

For the basic case of $L_2$ optimal transport between two probability measures on a Euclidean space, the regularity of the coupling measure and the transport map in the tail regions of these measures is studied. For this purpose, Robert McCann's classical existence and uniqueness results are extended to a class of possibly infinite measures, finite outside neighbourhoods of the origin. For convergent sequences of pairs of such measures, the stability of the multivalued transport maps is considered, and a useful notion of locally uniform convergence of these maps is verified under light assumptions. Applied to regularly varying probability measures, these general results imply the existence of tail limits of the transport plan and the coupling measure, these objects exhibiting distinct types of homogeneity.
Weighted Estimates of Singular Integrals and Commutators in the Zygmund Dilation Setting

The main purpose of this paper is to establish weighted estimates for singular integrals associated with Zygmund dilations via a discrete Littlewood--Paley theory, and then apply it to obtain the upper bound of the norm of commutators of such singular integrals with a function in the little bmo space associated with Zygmund dilations. Examples of such singular integrals associated with Zygmund dilations include a class of singular integrals studied by Ricci--Stein and Fefferman--Pipher, as well as a singular integral along a particular surface studied by Nagel--Wainger. We show that the lower bound of the norm of this commutator is not true for any singular integral in the class considered in Ricci--Stein and Fefferman--Pipher, but does in fact hold for the specific singular integral studied in Nagel--Wainger. In particular this implies that the family of singular integrals studied in these papers is not sufficiently general to contain the operator of Nagel--Wainger, which we show is of significance in this theory.
Factors Influencing Early Childhood Administrators' Decisions regarding the Adoption of Computer Technology

This research examined several key factors involved in decisions regarding adoption of microcomputers for administrative and instructional uses in early childhood education. Eighty directors representing both nonprofit and private proprietary early childhood programs participated in the study. Four sets of decision-making influences were considered: relevant past experiences (i.e., experiences with and knowledge about computers, experience with other educational innovations, and background in math and science), future expectancies (i.e., self-efficacy expectations and expectancies regarding the consequences of computer use), openness to change (i.e., self-perception of innovativeness and professional orientation), and social support. Multivariate prediction analyses revealed that knowledge and experience, self-efficacy for computer use, and professional orientation were the most salient factors associated with microcomputer use in the early childhood setting.
Make it move: a movement design method of simple standing products based on systematic mapping of torso movements & product messages

Human communication significantly relies on the expressivity of their body movements. Based on these body language experiences, humans tend to extract meanings even from movements of objects. This paper begins with the above human tendencies to create a design method that can help product designers make their products move to communicate. As a research vehicle, we created a robotic torso prototype and utilized it to collaborate with movement experts, and listed up possible expressive movement components. We then built a mapping matrix that links these movements to general product messages. A method which utilizes this mapping matrix was developed to help designers determine a set of effective movements that can communicate specific product messages. Lastly, a design workshop was conducted to identify the usefulness of the proposed method. We expect the procedures and findings of this study to help researchers and designers approach affective user experience through product movement design.
Experimental hypogonadism: insulin resistance, biochemical changes and effect of testosterone substitution

Abstract Background We sought to clarify the role of testosterone substitution in terms of insulin resistance and metabolic profile dysregulation in hypogonadism. Methods Twenty-nine male Wistar rats aged 11–12 weeks were divided in three groups: control (C, n = 10), sham operation; orchiectomy (ORX, n = 9); and orchiectomy + testosterone substitution (ORX+T, n = 10). Blood samples were obtained at day 1 (operation), after 10 days (intramuscular T injection 100 μg/100 g b.w.), 25 days (second T injection) and 40 days (sacrifice). Results Hormonal replacement significantly attenuated the negative effect of orchiectomy on insulin resistance as indicated by the successive changes in both insulin levels (1.44 ± 2.94 vs. 4.10 ± 2.47 vs. 1.78 ± 0.68 ng/mL, for D1, D10 and D40, respectively; p = 0.028 and p = 0.022, respectively) and HOMA-IR index (1.36 ± 2.75 vs. 3.68 ± 1.87 vs. 1.74 ± 0.69 ng/mL, for D1, D10 and D40, respectively; p = 0.024 and p = 0.026, respectively) in the ORX+T group. Irisin levels peaked at the 10th postoperative day and were decreased at the end of the experiment (0.27 ± 0.11 vs. 0.85 ± 0.54 vs. 0.02 ± 0.07 ng/mL for D1, D10 and D40, respectively; p = 0.028 in both cases), whereas resistin levels did not differ. Experimental hypogonadism results in an unfavorable lipid profile and insulin resistance, which is not observed when the ORX animals are substituted for T.
College Enrollment Decision for Nontraditional Female Students

COLLEGE ENROLLMENT DECISION FOR NONTRADITIONAL FEMALE STUDENTS Cindy Lorentzen Marquette University, 2014 Increasingly, more women are attending college and earning their degrees than men. This qualitative case study examined the reasons why adult females decide to enroll in college to earn their bachelor’s degree. With multiple roles and responsibilities creating time constraints that stack the odds against the completion of their degree, many women experience delays as well as starts and stops in their educational journey over many years. The findings of this qualitative research study aligned with a review of the literature. With a sense of hopefulness and determination, adult females are resilient and have a strong desire to achieve their goal of earning a college degree to advance their careers, achieve personal fulfillment, and serve as a role model for their families. As a result of their education, adult females are transformed through enhanced confidence as well as broader knowledge and perspective. These nontraditional female students look for nontraditional ways of learning that are designed to fit their busy lifestyles. NONTRADITIONAL FEMALE COLLEGE ENROLLMENT DECISION i
Photoelectric Dual Control Negative Differential Resistance Device Fabricated by Standard CMOS Process

To prepare a desired negative differential resistance (NDR) device by standard complementary-metal–oxide–semiconductor (CMOS) process, a photoelectric dual control NDR device with a PNP bipolar-junction-transistor (BJT) and an NPN BJT was designed and fabricated by using the Si-base standard 0.18 μm CMOS process without any process modification and a special substrate. In order to reduce the valley current under optical control, a metal mask was added to the NDR device. The results show that the device exhibits good NDR characteristics under either voltage-control or photo-control. Under voltage-control, a low volley current (0.23 pA) and a high peak-to-valley current ratio (1.4 × 1010) are obtained at less than 1 V. Under photo-control, the two parameters obtained at less than 0.5 V, are 37 nA and 4827, respectively. Also, the device displays fine S-type NDR characteristics and nice maintaining response function under photo-control. These superior photoelectric NDR characteristics endow the device with greatly potential application in the photoelectric logic circuits.
The Influence of the Phonological Characteristics of a Language on the Functional Units of Reading: A Study in French

Taft (1992) reported results supporting the idea that the "Body of the Boss" (gos) is an important unit in the visual recognition of English polysyllabic words. "Boss" refers to the orthographically-defined first syllable of a word (e.g., the lam of lament); "Body" refers to the part of that syllable which follows the initial consonant(s) (e.9., the am of lam). The primary evidence supporting this notion was that the pronunciation of an ambiguously pronounceable nonword could be biased by the pronunciation of a preceding word when they shared their sos, but not when they shared their phonologically-defined first syllable. Three experiments were conducted in French, to examine whether the syllable dominates as a unit of orthographic representation when the language has a clear phonological syllable structure. To construct ambiguously pronounceable nonwords, upper case letters were used and the first syllable always contained an E, which could be pronounced either as y' or e. Nonwords (e.g.,MeRANE) were preceded by an upper case version of a word sharing a BoB (e.g., fdroce) or a first syllable (e.g., mdduse). The pronunciation of the nonword's E was biased by the syllable and not by the aon, implying that the syllable, but not the non, is a relevant structure in the processing of visually presented French words.
Towards a discovery-oriented ethnography in researching the professional context of higher education

Today anthropologists seem to be increasingly studying phenomena in their own societies. Many have a focus on policies in organizations and an interest in explicating cultural phenomena constituted by power and governance. Consequently, a recent interest has emerged in Michel Foucault's philosophy, especially as an inspiration for ethnographic analysis. However, this type of inquiry is problematic, because the Foucauldian perspective contributes to a pre-established idea of social reality, hence distorting essential aspects of the process of discovery. This article aims to provide an alternative to recent trends in Foucauldian-inspired analysis by showing how Eric Wolf's anthropological project can contribute to a more discovery-oriented ethnography. Wolf's concept formation of structural power, tactical power, chain of signification and cultural brokers is closely examined in relation to studying organizational phenomena. In particular, an analysis based upon Wolf's concept can be useful for an increased understanding of policy processes in the field of higher education.
New Constraints on the Nuclear Equation of State from the Thermal Emission of Neutron Stars in Quiescent Low-mass X-Ray Binaries

This paper presents a new analysis of the thermal emission from the neutron star (NS) surface to constrain the dense matter equation of state. We employ an empirical parameterization of the equation of state with a Markov Chain Monte Carlo approach to consistently fit the spectra of quiescent low-mass X-ray binaries in globular clusters with well-measured distances. Despite previous analyses predicting low NS radii, we show that it is possible to reconcile the astrophysical data with nuclear physics knowledge with or without including a prior on the slope of the symmetry energy Lsym. With this empirical parameterization of the equation of state, we obtain radii of the order of about 12 km without worsening the fit statistic. More importantly, we obtain the following values for the slope of the symmetry energy, its curvature Ksym, and the isoscalar skewness parameter Qsat: MeV, MeV, and MeV. These are the first measurements of the empirical parameters Ksym and Qsat. Their values are only weakly impacted by our assumptions, such as the distances or the number of free empirical parameters, provided the latter are taken within a reasonable range. We also study the weak sensitivity of our results to the set of sources analyzed, and we identify a group of sources that dominates the constraints. The resulting masses and radii obtained from this empirical parameterization are also compared to other measurements from electromagnetic observations of NSs and gravitational wave signals from the NS–NS merger GW170817.
Multicast instant channel change in IPTV systems

IPTV delivers television content over an IP infrastructure with the potential to enrich the viewing experience of users by integrating data applications with video delivery. From an engineering perspective, IPTV places both significant steady state and transient demands on network bandwidth. Typical IPTV streaming techniques incur delays to fill the play-out buffer. But, when viewers switch or surf channels, it is important to minimize this user-perceived latency. Traditional Instant Channel Change (ICC) techniques reduce this latency by having a separate unicast assist channel for every user changing channels. Instead, we propose a multicast-based approach using a secondary ldquochannel change streamrdquo in association with the multicast of the regular quality stream for the channel requested. During channel change events, the user does a multicast join to this new stream and experiences smaller display latency. In the background, the play-out buffer of the new full-quality multicast stream is filled. Then, the transition to the new channel is complete. We show that this approach has several performance benefits including lower bandwidth consumption even during flash crowds of channel changes, lower display latency (50% lower), and lower variability of network & server load. The tradeoff is a lower quality video during the play-out buffering period of a few seconds. Our results are based upon both synthetic channel change arrival patterns as well as traces collected from an operational IPTV environment.
Anti-nephrotoxic activity of some medicinal plants from tribal rich pockets of Odisha

Background: Gentamicin, a strong cationic drug accumulated at biological membranes causes net increase in oxidative stress and lipid peroxidation leading to necrotic changes in renal tubles and consequently precipitates acute nephrotoxicity. Several phytoconstituents and plants extracts demonstrated significant anti-oxidant and cyto-protective activities. Vitex negundo Linn. (VN), Oroxylum indicum Vent. (OI) and Barringtonia acutangula Linn. (BA) are widely found throughout the Asian sub-continent including India, used extensively in different forms of Indian traditional medicine like Ayurveda and Unani. Objective: Nephroprotective activity of extracts of VN roots, OI whole plant and BA leaves were investigated against experimentally induced acute nephrotoxicity [Gentamicin (i.p; 80mg/kg for 7 days)] in Wistar rats as test animals. Materials and Methods: The rats were treated with Cystone (5 mL/kg; p.o) taken as positive control and methanol-dichloromethane (1:1) extracts of VN, OI and BA (200 mg/kg; p.o) as test drugs for 7 days. Following the said treatments, biochemical parameters of urine (volume, creatinine and lactate dehydrogenase (LDH)) and serum (urea, creatinine, albumin and total protein) were estimated. Renal anti-oxidant markers viz., superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lipid peroxidation (LPO) in renal tissue were assayed. Tissue sections of kidneys from different groups were made and histopathological features were observed. Result: The extracts of VN, OI and BA significantly attenuated the nephrotoxicity by elevation of body weight, CAT, GPx and SOD or lowering urine LDH and creatinine, serum urea; serum creatinine and LPO respectively. Histopathological score of VN, OI and BA treated groups were 1+, 2+ and 2+ respectively against 4+ of the toxic group. Conclusion: The findings suggested the significant nephroprotection of VN roots followed by OI whole plant and BA leaves.
Envy, Resentment, Schadenfreude, and Sympathy: Reactions to Deserved and Undeserved Achievement and Subsequent Failure

This study tested the hypothesis that schadenfreude (or pleasure in another's misfortune) would be more closely related to resentment and a wish to correct a perceived injustice than to envy, and that sympathy would involve different processes. Participants were 184 undergraduates who responded to scenarios in which a student with a record of either high or average achievement that followed high or low effort subsequently suffered failure under conditions where there was either high or low personal control. Results showed that resentment about the student's prior achievement could be distinguished from envy. Schadenfreude about the student's subsequent failure was predicted by resentment and not by envy. Sympathy was not predicted by either resentment or envy. Deservingness was a key variable in the models that were tested.
Deep Learning in Alzheimer's Disease: Diagnostic Classification and Prognostic Prediction Using Neuroimaging Data

Deep learning, a state-of-the-art machine learning approach, has shown outstanding performance over traditional machine learning in identifying intricate structures in complex high-dimensional data, especially in the domain of computer vision. The application of deep learning to early detection and automated classification of Alzheimer's disease (AD) has recently gained considerable attention, as rapid progress in neuroimaging techniques has generated large-scale multimodal neuroimaging data. A systematic review of publications using deep learning approaches and neuroimaging data for diagnostic classification of AD was performed. A PubMed and Google Scholar search was used to identify deep learning papers on AD published between January 2013 and July 2018. These papers were reviewed, evaluated, and classified by algorithm and neuroimaging type, and the findings were summarized. Of 16 studies meeting full inclusion criteria, 4 used a combination of deep learning and traditional machine learning approaches, and 12 used only deep learning approaches. The combination of traditional machine learning for classification and stacked auto-encoder (SAE) for feature selection produced accuracies of up to 98.8% for AD classification and 83.7% for prediction of conversion from mild cognitive impairment (MCI), a prodromal stage of AD, to AD. Deep learning approaches, such as convolutional neural network (CNN) or recurrent neural network (RNN), that use neuroimaging data without pre-processing for feature selection have yielded accuracies of up to 96.0% for AD classification and 84.2% for MCI conversion prediction. The best classification performance was obtained when multimodal neuroimaging and fluid biomarkers were combined. Deep learning approaches continue to improve in performance and appear to hold promise for diagnostic classification of AD using multimodal neuroimaging data. AD research that uses deep learning is still evolving, improving performance by incorporating additional hybrid data types, such as—omics data, increasing transparency with explainable approaches that add knowledge of specific disease-related features and mechanisms.
Blue Nevi of the Müllerian Tract: Case Series and Review of the Literature

Background. Blue nevi are rare in the cervix and vagina. Melanocytes are not normally found in these sites and have been hypothesized to arise either from the Schwann cells of stromal nerves or from melanocytic precursors which have aberrantly migrated from the neural crest to rest in the Müllerian stroma. Because of their rarity (3 previous cases in the literature), vaginal blue nevi have not previously been studied with immunohistochemical and ultrastructural analysis. Design. We describe 3 cases of blue nevus occurring in the Müllerian tract, 1 in the vagina and 2 in the endocervix. Results. The vaginal lesion was seen during routine examination of a 40-year-old woman. The endocervical blue nevi were incidental findings in hysterectomies performed for leiomyomata and endometrial serous carcinoma in women aged 44 and 57 years, respectively. All 3 cases showed loose aggregates of cytologically benign, pigmented, dendritic spindle cells in the superficial stroma. They were immunoreactive for S100 and melan-A, but not HMB45. Ultrastructural analysis revealed numerous melanosomes, with no Schwannian features identified. Compared with the endocervical lesions, the vaginal nevus cells were more heavily pigmented, and on electron microscopy, a greater proportion of stage IV melanosomes were seen. Conclusions. We provide the first immunohistochemical and ultrastructural findings in a vaginal blue nevus, which confirm that it is of a similar nature to the endocervical blue nevi. Ultrastructurally, our results support a melanocytic rather than Schwannian origin for Müllerian blue nevi.
An Examination of the Own-Race Preference in Infancy

The goal of this dissertation was to better characterize the nature of infants’ visual preference for own-race faces, and to test two theories regarding its origin. Chapters I and II assessed whether the race bias in infancy could be attributed to an enhanced ability to discriminate familiar faces. Based on this account, infants' race preference should be more pronounced for female pairs of faces, and should only arise whenever different individuals are presented across trials. In Chapter I, White 3-monthold infants saw multiple male and female pairs differing in race. Looking times revealed a significant own-race preference only when male faces were presented. In Chapter II, participants viewed different photographs of the same two Black and White faces across 8 trials. Findings still revealed a robust own-race visual bias uniquely in male pairs. Collectively, these findings provide evidence against the notion that differences in face discriminability are responsible for babies’ racial preference. Moving to the question of origin, Chapter III tested the hypothesis that the malespecific own-race preference is rooted in an evolutionary threat response. Participants were presented with male and female pairs of own-and other-race faces displaying averted eye gaze, a cue meant to reduce threat. Findings were inconclusive as a looking time bias specifically toward White males yet again emerged. Finally, Chapter IV examined the idea that infants’ early visual preferences are shaped by experience. Three-month-olds were shown a video of an ownand other-race
