Macromodels in the frequency domain analysis of microwave resonators

This paper describes a 1-V operation Bluetooth RF transceiver in 0.2-/spl mu/m CMOS SOI. The transceiver integrates a radio-frequency transmit/receive switch, an image-reject mixer, a quadrature demodulator, g/sub m/-C filters, an LC-tank voltage-controlled oscillator, a phase-locked loop synthesizer, and a power amplifier. The phase shifter in the quadrature demodulator is tuned dynamically to track the carrier-frequency drift allowed in the Bluetooth specification. The g/sub m/ cell in the filters uses depletion-mode pMOS transistors. In order to achieve 1-V operation, LC-tuned-folded and transistor-current-source-folded circuits are used in the RF and IF building blocks, respectively. In order to minimize power consumption, the current flowing through the circuit is optimally shared between the folded stages. A tuning circuit for the g/sub m/-C filters and a bias generation circuit ensure stable transceiver performance. The transceiver shows -77-dBm sensitivity at 0.1% bit error rate and consumes 33 and 53 mW from 1 V in the transmit and receive modes, respectively.
Continuous Free-Flap Monitoring with Tissue-Oxygen Measurements: Three-Year Experience

Early recognition of flap failure is a prerequisite for flap salvage. Many methods are used to monitor free flaps. The time interval for re-establishing vascular patency is the limiting factor for a successful revision. Prompt re-operation and a rapid and sufficient correction of the microvascular anastomosis are necessary to maintain flap viability. The Licox Catheter pO 2 Micro-Probe instrument is used for continuous determination of oxygen partial pressure (pO 2 ) in body fluids and tissue (p ti O 2 ). Over a period of 3 years, 60 free tissue transfers to head and neck, trunk, and upper and lower extremities were monitored using the Licox Catheter Probe System. The flexible Licox Catheter pO 2 Micro-Probe detected circulatory changes and failure in all cases, with no false positives or negatives. In all cases in which the arterial pedicle failed, the p ti O 2 dropped rapidly; in cases of venous insufficiency, the p ti O 2 value decreased more or less slowly. In all failing flaps, a p ti O 2 decrease of 10 mmHg within a half-hour, or a p ti O 2 drop below 10 mmHg was observed. These are observations which are useful as precise indicators for vascular complications and flap failure. Based on the authors' observations and data, the Licox probe is a sensitive and accurate monitoring system for all types of free flaps.
Burnout Among Foreign-Born and Native Swedish Women: A Longitudinal Study

The authors of this study addressed burnout experiences (generally defined as chronic depletion of an individual's energetic resources') over time in relation to other factors (e.g., distress, sleep difficulties, job demands, etc.) among foreign-born women and Swedish native women living in Stockholm. The study design was a longitudinal panel survey with two waves one year apart. In the first wave, 3,616 of 6,000 randomly selected women took part, and 2,300 of the initial 3,616 women also participated in the second wave; 427 were foreign-born women, and 1,873 were Swedish native women. Baseline/emerging distress, emerging sleep difficulties, worsening general social support, job demands at baseline/escalating during the assessment period, emerging unemployment, constraints in social support at work, and sustained/emerging financial strain were associated with future burnout, regardless of background. More foreign-born women than Swedish native women reported burnout, with these differences maintained at one-year follow-up. The factors related to burnout were largely the same in both groups, but smoking and cardiovascular disease were related to burnout only among foreign-born women. Younger age, job demands, and working hours were associated with burnout among Swedish native women. The authors found that the women had concurrent problems such as burnout, distress, and sleep problems, but foreign background was not independently related to burnout.
Economic and psychological perspectives on CEO compensation: a review and synthesis

To many, the principal--agent model is the obvious lens through which executive pay should be viewed. Such a sentiment sits uncomfortably with a large number of empirical studies suggesting that the process of determining executive pay seems to be more readily explained by recourse to arguments of managerial power and influence. This article investigates the micro-underpinnings of boardroom behavior in order to explain this departure from principal--agency theory's argument that executive compensation serves to align interests between the owners of the company and its senior managers. We find that there are strong interaction effects among social influence variables and the social setting of boardroom activity. Generous pay awards, bearing only a weak connection to corporate performance, are explained in the context of the social psychology of the boardroom. These results and a review of the empirical research, suggest the need for a more comprehensive model of executive compensation that incorporates both economic and psychological determinants.

Network Overlap and Content Sharing on Social Media Platforms

Improving content sharing on social media platforms helps firms enhance the efficacy of their marketing campaigns. The authors study the impact of network overlap—the overlap in network connections between two users—on content sharing in directed social media platforms. The authors propose a hazards model that flexibly captures the impact of three measures of network overlap (i.e., common followees, common followers, and common mutual followers) on content sharing. Using data on content sharing from two directed social media platforms (Twitter and Digg), the authors establish that a receiver is more likely to share content from a sender with whom they share more common followees, common followers, or common mutual followers even after accounting for other measures. In addition, common followers have a higher effect than common mutual followers on the sharing propensity of the receiver. Finally, the effect of common followers and common mutual followers is positive when the content is novel but decreases, and may even become negative, when many others have already shared it. Collectively, these results have a bearing for marketers to more effectively target users for spreading content on social media platforms.
A determinant of polyomavirus virulence enhances virus growth in cells of renal origin

We have identified a strain of polyomavirus, Py(L), which is unusual in causing acute morbidity and early death after inoculation of newborn mice. We determined that these animals died of kidney failure associated with extensive, virus-mediated destruction of renal tissue. Interestingly, the Py(L) strain infects baby mouse kidney cell cultures more efficiently than do other strains.

Explaining users' critical incidents of physical mobile interactions

Salo, Markus Explaining Users’ Critical Incidents of Physical Mobile Interactions Jyvaskyla: University of Jyvaskyla, 2013, 69 p. (Jyvaskyla Studies in Computing, ISSN 1456-5390; 178) ISBN 978-951-39-5501-4 (nid.) ISBN 978-951-39-5502-1 (PDF) At times, users have critical incidents with information systems (IS). Critical incidents are single experiences, which the user considers outstandingly positive or negative. For example, a critical incident may exceed one’s desires by unusual success and joy or tear one apart because of failures and frustration. Previous research has found critical incidents highly influential and powerful for customer relationships, and thus crucial for product and service providers. In the context of IS and mobile applications, researchers have studied thoroughly neither the process of critical incidents nor user behaviors after such incidents. For instance, there are no explanations as to why critical incidents occur in the first place and how the situational context influences users’ postexperience behaviors. To address the identified gap in the research, this thesis investigates qualitatively and quantitatively several hundred descriptions of critical mobile incidents collected with the critical incident technique (CIT) from actual users of mobile applications. The focus lies particularly on applications that users employ to physically interact with surrounding real-world objects and places. The results attempt to extend current knowledge in the form of a new process model for mobile experiences (MEP), providing rich insights about each of the model’s six elements: trigger, interaction, positive/negative perception, situational context, peak moments, and post-experience behaviors. One interesting finding is that users are less likely to engage in negative behaviors after negative critical incidents that take place outdoors or in vehicles than after indoor incidents. In the theoretical implications, it is argued that researchers should acknowledge six meaningful elements regarding critical ISrelated incidents instead of studying just one or a limited set of elements. As practical implications, application providers and other industry stakeholders are encouraged to systematically analyze each element of the MEP model one by one, reflect the element and its insights with an application of their interest, and then take the necessary actions.
Magnetic Resonance Imaging in Viral and Prion Diseases of the Central Nervous System

Abstract The early detection and specific diagnosis of viral infections of the central nervous system are important because many of these diseases are potentially treatable. However, clinical symptoms and physical examination are often nonspecific, and rapid diagnostic tests are available for some, but not all, viruses. Neuroimaging, in conjunction with clinical history and laboratory tests, plays an important role in narrowing the differential diagnoses. In this article, we review the clinical features, imaging characteristics, diagnosis, and treatment of the more common viral infections and prions that involve the central nervous system.
Illness experience in patients with hepatocellular carcinoma: an interpretative phenomenological analysis study

Aims Hepatocellular carcinoma (HCC) is common in Asia and has implications for compromised health-related quality of life. We report a qualitative study to explore the impact of HCC on patients’ lives and the adjustment process. Methods Thirty-three adult patients with HCC in Taiwan (age from 31 to 76 years) took part in a semistructured interview. The interview guide included illness experience, strategies used to deal with the disease, and any significant concerns in their current life. Data were analyzed using interpretative phenomenological analysis. Results Three main themes were identified. These included: (a) the impact of disease: HCC was associated with physical symptoms and psychosocial stress, as well as positive changes; (b) illness perceptions: patients perceived HCC as a long-term and chronic disease that could not be cured but might be controlled; and (c) coping strategies: these included focusing on managing HCC and its symptoms, emotional responses, and leading a normal life. Conclusion Patients’ physical condition, their illness perceptions, and coping strategies all contributed to their disease adjustment. Our results suggest that patients in Taiwan are as keen for information about their disease as described in Western cultures. Cross-cultural work is needed to enhance our understanding about how the social or cultural contexts shape individuals coping with cancer.
JNC8 guidelines for the management of hypertension in adults.

Hypertension is one of the most important preventable contributors to disease and death in the United States, leading to myocardial infarction, stroke, and renal failure when it is not detected early and treated appropriately. The Eighth Joint National Committee (JNC 8) recently released evidence-based recommendations on treatment thresholds, goals, and medications in the management of hypertension in adults.
Exploring the Relationships Among Travel Multimodality, Driving Behavior, Use of Ridehailing and Energy Consumption

In the last decade, advances in information and communication technologies and the introduction of the shared economy engendered new forms of transportation options and, in particular, shared mobility. Shared mobility services such as carsharing (e.g., Zipcar and Car2go), dynamic ridesharing (e.g., Carma), ridehailing (e.g., Uber and Lyft), and bike/scooter sharing (e.g., CitiBike, Jump Bike, Bird, and Lime) have gained growing popularity especially among subgroups in the population including college-educated or urban-oriented young adults (e.g., millennials). These emerging transportation services have evolved at an unprecedented pace, and new business models and smartphone applications are frequently introduced to the market. However, their fast-changing nature and lack of relevant data have placed difficulties on research projects that aim to gain a better understanding of the adoption/use patterns of such emerging services, not to mention their impacts on various components of travel behavior and transportation policy and planning, and their related environmental impacts.This report builds on an on-going research effort that investigates emerging mobility patterns and the adoption of new mobility services. In this report, the authors focus on the environmental impacts of various modality styles and the frequency of ridehailing use among a sample of millennials (i.e., born from 1981 to 1997) and members of the preceding Generation X (i.e., born from 1965 to 1980). The total sample for the analysis included in this report includes 1,785 individuals who participated in a survey administered in Fall 2015 in California. In this study, the researchers focus on the vehicle miles traveled, the energy consumption and greenhouse gas (GHG) emissions for transportation purposes of various groups of travelers. They identify four latent classes in the sample based on the respondents’ reported use of various travel modes: drivers, active travelers, transit riders, and car passengers. They further divide each latent class into three groups based on their reported frequency of ridehailing use: non-users, occasional users (who use ridehailing less than once a month), and regular users (who use it at least once a month). The energy consumption and GHG emissions associated with driving a personal vehicle and using ridehailing services are computed for the individuals in each of these groups (12 subgroups), and the authors discuss sociodemographics and economic characteristics, and travel-related and residential choices, of the individuals in each subgroup.View the NCST Project Webpage
Meat molecular detection: Sensitivity of polymerase chain reaction-restriction fragment length polymorphism in species differentiation of meat from animal origin

Three restriction enzymes were used in Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) using the mitochondrial cytochrome b region to establish a differential diagnosis which detect and discriminate between three meat species: pork, cow and chicken. DNA was extracted from samples containing meat of a single animal such as raw pork (Sus scrofa domesticus), chicken (Gallus gallus) and cow (Bos taurus) as well as mixed samples of two species of animals in different ratios. The amplified 359 base pairs (bp) portion of the mitochondrial cyt b gene from pure or mixed samples in different ratios was cut using three different restriction enzymes resulting in species specific restriction fragment length polymorphism (RFLP). This technique proved to be extremely reliable in detecting the presence of low levels of target DNA obtained from a 0.25 mg component in a particular mixed meat sample. This revealed the cyt b region as highly conserved and consequently a good molecular marker for diagnostic studies. Thus, this technique can be applied to food authentication for the identification of different species of animals in food products.
Risk factors of Osteoarthritis Knee - A Cross-sectional study

A hospital based cross sectional study was carried out in a tertiary care centre to study the risk factors of Osteoarthritis of Knee among patients attending Orthopaedics OPD. All patients aged between 40 and 65 years were included in the study. A total of 102 patients for a period of four months were studied. Nearly two thirds of our study subjects were women. OA increased with age and BMI. Risk factors like family history, history of knee injury and occupational knee bending were seen in only few of our study subjects. There is need to spread awareness among people to adopt preventive measures at an earlier age along with healthy lifestyle to reduce the body weight and hence the risk of OA.
Survey of Glaucoma in an Eye Clinic in Ghana, West Africa

PurposeTo report the various types of glaucoma among West African patients presenting to an eye clinic in Ghana. MethodsA complete evaluation was performed in 198 consecutive Ghanaian glaucoma patients. Main outcome measures included intraocular pressure, visual acuity, gonioscopy findings, visual field, and total number of glaucoma medications. ResultsThe most common form of glaucoma was primary open-angle glaucoma (44.2%). Open-angle glaucoma suspects also comprised a large percentage of the group (30.5%). Chronic angle-closure glaucoma was diagnosed in 6.6% of the patients. ConclusionsPrimary open-angle glaucoma is the most common form of glaucoma being treated in this outpatient eye clinic in Ghana. Chronic angle-closure glaucoma was the second most common form of glaucoma in this series and was usually undiagnosed due to a lack of gonioscopic evaluation. Gonioscopy is an important diagnostic tool that should be promoted to guide more effective glaucoma treatment in this region. Pseudoexfoliation and pseudoexfoliation-associated glaucoma were not seen in this population.
Distribution and ultrastructure of tachykinin‐like immunoreactivity in the frog (rana esculenta) spinal cord, notably, the dorsal horn

Tachykinins are involved in pain transmission at the spinal level. In frog, at least four tachykinins [TK] have been isolated from the brain, but their organization in the dorsal horn of the spinal cord is still poorly known. We have reexamined TK distribution by immunocytochemistry using an antibody recognizing the sequence common to all tachykinins in the spinal cord and dorsal root ganglia of the green frog Rana esculenta. A dense tachykinin‐like immunoreactivity (TK‐LI) was observed in the dorsolateral fasciculus or Lissauer's tract running ventromedial to the entry of the dorsal root and in numerous small and medium‐sized dorsal root ganglion cells showing a primary afferent origin for part of TK‐LI of the dorsal horn. The observation of numerous cell bodies in the dorsal horn, in addition, suggested a local or propriospinal origin. One group of cells was localized at the entrance of the Lissauer's tract TK‐LI fibers into the dorsal horn, and another group was localized in the upper dorsal horn, a region with a low density of TK‐LI fibers. It was suggested that the latter group may correspond to neurokinin B. Electron microscopic examination of the Lissauer's tract showed numerous immunoreactive axons, some located at the center of glomerular‐like arrangements, suggesting that the information brought by these fibers may be transmitted and most probably modulated before their entry in the dorsal horn. In conclusion, the functional organization of tachykinins in the frog spinal cord seems to be similar to that of mammals, albeit with a different morphological organization. J. Comp.

Hope for the Hygiene Hypothesis: When the Dirt Hits the Fan

The hygiene hypothesis was developed in response to data suggesting that the increase in allergic diseases as well as asthma was secondary to a reduced exposure to infectious stimuli. Indeed, the epidemiologic changes, resulting in an increase in atopic disease, have been impressive and intriguing. Furthermore, although there clearly is a genetic component to atopic diseases, genetics cannot account for a marked increase in the incidence and prevalence of allergic manifestations within a few generations. Thus, environmental factors have been suggested as responsible for the changing prevalence. There are two—not mutually exclusive—possibilities, namely, that substances that promote atopy have been added to the environment or that factors that provided protection from allergic disease were lost from the environment. Both outdoor and indoor pollution, along with a long list of other environmental factors, have been proposed. It is of interest that in many developed countries, certain types of pollution have decreased, whereas the prevalence of atopic disease has increased. In this review, we have explored a detailed analysis of a large number of studies that have focused on this issue and suggest that, although the hygiene hypothesis has merit, the stimuli responsible for the new epidemiology remain enigmatic.
Leadership development program: a survey on perceived program success, employment satisfaction, and intent to stay

This research project focused on the measurement of the effect of an organization ' s leadership development program relating to employees' perceived improvement in job satisfaction and intent to stay. There are three core elements of the leadership development program: teamwork, commitment to the team and leadership. The literature review focused on research of the three core elements and why they are important in creating leaders and leadership within an organization. The focus of the study was only in the Canadian Operations of the organization. The survey was designed to measure the relationship between the program' s core elements and employees ' job satisfaction and intent to stay. The majority of the results poorly supported the hypotheses due to the very small survey population. There were some promising results with positive correlations between intent to stay for ethical considerations of the program and a company that offers such training. There are opportunities for the organization to use these results and develop a continual improvement process for the program to focus on, developing the connections between the core elements and how the program is initiated within the organization. There were several limitations such as small population size, the research questions themselves and focus on just the Canadian Operations.
