An efficient RF energy harvesting system

This paper proposes a new radio frequency (RF) energy harvesting system that operates over the Wi-Fi 802.11 b/g band at low input power levels. The system presented herein achieves good power conversion efficiencies (PCEs) over a power range that extends from (−20 dBm) to (3 dBm). A directive slot antenna is incorporated to drive the rectification process of the designed rectenna. The rectenna system is measured and tested, along with a power management circuitry, for design validation purposes. A good agreement between simulated and measured results is attained.
The Blood Vessels of the Human Skin

while the clinical symptoms were very similar and typical histories, were obtained of several other members of the family having been insane and having chorea, yet the pathological pictures miiacroscopically were very different. The brain of the woman was smiiall and firm, there wras no thickening of the pia-arachnoid, the ventricles were only slightly dilated, the cerebro-spinal fluid was only sliglhtly in oxcess, and there was apparently no wasting of the grey matter or basal ganglia; the brain of the mani was large and very soft throughout; there was marked thickeninig of the pia-arach'noid, which was also adherent; the ventricles were very greatly dilated and the subarachnoid and ventricular fluid in great excess; there was marked frosting of the ependyma of the lateral and fourth vs'ntricles. The grey matter and the corpus striatum were brown, very so'ft,. and considerably atrophied, especially the caudate nucleus. In the brain of the woman the cerebral arteries were in good condition; in the brain of the iiman they showed numerous rings of sclerosis. Other details are as follows:
Haptic media and the cultural techniques of touch: The sphygmograph, photoplethysmography and the Apple Watch

This article draws upon cultural techniques theory to propose an approach to studying haptic media as media technologies which train or discipline touch and which serve to produce touch itself as a coherent and ‘proper’ communicative technology. This article analyses the different forms of touch which have coalesced around the sphygmograph, a nineteenth-century pulse writing technology, and photoplethysmography, a contemporary heart rate–measuring technology which has been remediated as part of the Apple Watch. This article demonstrates that nineteenth-century clinicians drew upon the sphygmograph to authorise doctorly touch as newly ‘proper’ within a changed technological context. By contrast, an analysis of the place of error within the Apple Watch’s photoplethysmograph demonstrates how contemporary self-quantifiers are encumbered with an unreliable measuring apparatus which can only generalise a form of ‘improper’ touch, touch which fails to know the body and which remains tied to a ‘proper’ touch which lies elsewhere.
Murine Model of Immune-Mediated Rejection of the Acute Lymphoblastic Leukemia 70Z/31

70Z/3 is a murine pre-B cell leukemia line derived from BDF1 mice and has been used in the study of signaling pathways in B cells. 70Z/3 cells were initially found to cause widespread disease upon injections in animals. We have isolated 70Z/3 variants divergent in their capacity to lead to morbidity after injections. One variant, 70Z/3-NL, elicits an immune response protecting the animal from tumor growth. Another variant, 70Z/3-L, does not induce an effective immune response and causes morbidity. We demonstrated that both CD4+ and CD8+ T cells are required for the rejection of 70Z/3-NL cells. Interestingly, the immune response generated against 70Z/3-NL cells was found to protect against a challenge with the lethal variant, 70Z/3-L. This indicates that although both lines can be recognized and killed by the immune system, only 70Z/3-NL is capable of inducing a protective response. Further observations, using subclones isolated from 70Z/3-NL, demonstrated that immune recognition of a portion of the cells was sufficient for protection. Depletion of CD4+ and CD8+ T cells in animals injected previously with 70Z/3-NL cells showed that T cells, and not Abs, were required for the maintenance of the protection initiated by 70Z/3-NL. We tested the capacity of 70Z/3-NL cells to treat mice challenged with 70Z/3-L. We can delay injections of 70Z/3-NL and still provide protection for the animals. We have a model of immune-mediated rejection which will allow us to dissect the requirements for the initiation of immune responses against an ALL tumor cell line.
CCNU (lomustine), idarubicin and dexamethasone (CIDEX): an effective oral regimen for the treatment of refractory or relapsed myeloma

We report the results of a non‐randomized pilot study of an oral regimen comprising CCNU (lomustine; 25 or 50 mg/m2 on day 1), idarubicin (4‐demethoxydaunorubicin) (10 mg/m2 on days 1–3) and dexamethasone (10 mg b.d. on days 1–4) in patients with relapsed or refractory myeloma. Treatment was given every 28 d for a maximum of six courses. Sixty patients were entered of whom 57 were evaluable. Overall response rate (partial or minor response) was 49% with 30% of patients achieving a partial response (50% tumour reduction). Response rates were higher in patients with untested relapse than in those with refractory disease (overall response rates 56% vs. 31%). The major toxicity was neutropenia and the regimen was otherwise well tolerated. The median survival from entry of all patients was 15 months, with 30% of patients alive at 2 years. This regimen represents a useful addition to available treatment options.
Quickly Converging Renumbering in Network with Hierarchical Link-State Routing Protocol

We have developed an automatic network configuration technology for flexible and robust network construction. In this paper, we propose a two-or-more-level hierarchical link-state routing protocol in Hierarchical QoS Link Information Protocol (HQLIP). The hierarchical routing easily scales up the network by combining and stacking configured networks. HQLIP is designed not to recompute shortest-path trees from topology information in order to achieve a high-speed convergence of forwarding information base (FIB), especially when renumbering occurs in the network. In addition, we propose a fixed-midfix renumbering (FMR) method. FMR enables an even faster convergence when HQLIP is synchronized with Hierarchical/Automatic Number Allocation (HANA). Experiments demonstrate that HQLIP incorporating FMR achieves the convergence time within one second in the network where 22 switches and 800 server terminals are placed, and is superior to Open Shortest Path First (OSPF) in terms of a convergence time. This shows that a combination of HQLIP and HANA performs stable renumbering in link-state routing protocol networks. key words: HQLIP, HANA, renumbering, convergence time, link-state routing protocol
Calcium ion, an intracellular messenger of light adaptation, also participates in excitation of Limulus photoreceptors.

Photoreceptor cells of Limulus ventral eyes were bathed in artificial sea water (ASW) that contained 10 mM‐EGTA and no added Ca2+ (EGTA‐ASW). Test flashes elicited responses that increased to a maximum size within 10 min in EGTA‐ASW but did not change further when dark‐adapted cells were bathed for an additional 35 min in this solution. Light responses progressively declined from this maximum size if the cells were repetitively illuminated in EGTA‐ASW. In this state of reduced responsiveness, response amplitudes were further reduced by intracellular ionophoretic injection of EGTA; response amplitudes were increased by intracellular ionophoretic injection of Ca2+. Both of these findings are opposite to what is normally observed for cells bathed in ASW. Also, after repetitive illumination in EGTA‐ASW, both the slope of the response versus intensity relationship became steeper and light responses often had a delayed increase in amplitude. The light responses and the response versus intensity relation returned to normal when the bathing medium was changed back to ASW containing 10 mM‐Ca2+. The light‐induced rise in luminescence recorded from photoreceptors injected with the photoprotein aequorin (the 'aequorin response') declined by at most 50% after dark‐adapted photoreceptors were bathed in EGTA‐ASW for 45 min. However, the aequorin response progressively declined by 98% if cells were repetitively illuminated while bathed in EGTA‐ASW. The total intracellular Ca content of whole end‐organs was measured by atomic absorption spectroscopy. Total intracellular Ca content did not change significantly while photoreceptors were bathed in EGTA‐ASW even after repetitive illumination. We suggest that cytosolic Ca2+ is required by one or more steps in the mechanisms that link rhodopsin isomerization to both (i) an increase in the conductance of the cell membrane to Na+ and (ii) a release of Ca2+ from a light‐labile store.
High Speed 1.55 μm InAs/InGaAlAs/InP Quantum Dot Lasers

We report static and dynamic characteristics of InAs/InP quantum dot (QD) lasers emitting near 1.55 μm. The gain section was optimized for a high speed operation using a unique spatially resolved model. The measured modulation capability dependence on structural parameters (barrier width and the number of QD layers) is consistent with the model predictions. Short cavity lasers with a modal gain of more than 10 cm-1 per dot layer exhibit a small signal modulation bandwidth above 9 GHz and large signal modulation at up to 22 Gb/s with an on/off ratio of 3 dB.
Idiopathic Epilepsies with a Monogenic Mode of Inheritance

Idiopathic epilepsies account for ∼40% of all epileptic diseases. For a long time, it has been known that genetic factors play a major role in the etiology of these diseases. Although oligogenic or polygenic inheritance is suspected in most of the common syndromes, a few rare idiopathic epilepsies are single‐gene disorders. They offer a chance to identify candidate genes that also may be involved in epilepsies with complex inheritance. In recent years, major progress has been made regarding the analysis of genetic factors in idiopathic epilepsy. For the first time, gene defects could be linked to two idiopathic epilepsies. Mutations in the CHRNA4 gene, which codes for the α4 subunit of the neuronal nicotinic acetylcholine receptor, lead to autosomal dominant nocturnal frontal lobe epilepsy, a rare idiopathic partial epilepsy syndrome. Two highly homologous voltage‐gated potassium channels, KCNQ2 and KCNQ3, were found to be mutated in benign familial neonatal convulsions.
Reporting Capabilities, Financial Closing Time and Effects on Cost of Equity Capital

Facing a competitive capital market, firms have incentives to reduce information uncertainty by releasing earnings early. However, firms do differ in how soon they are able to release earnings to investors. We posit that firms cannot reduce their reporting time without underlying accounting information systems that are efficient and effective. Moreover, given the reduced information asymmetry and better managed accounting processes associated with timely reporting, we expect investors to require lower risk premiums on firms that are able to report faster than others. Empirically, we find that firms with shorter time-lags from fiscal-year end to earnings release date (financial closing time) are associated with lower implied cost of capital. This result is robust after controlling for known risk factors influencing cost of capital. We contribute to the body of knowledge by quantifying the benefits of effective information systems in terms of reduced financial reporting time and investors' required risk premium.

Computer Industry Executives: An Analysis of the New Barons' Compensation

In this paper we study the compensation determinants for CEOs in the computer industry and compare these findings with a large samp le of firms from other manufacturing and service industries. We examine whether superior performance is rewarded by higher levels of compensation and find cash-based compensation, such as salary and bonus, is influenced by performance. Depending on the gr owth prospects of the company, pay is tied either to accounting measures of performance or to stock return. In contrast, stock-based compensation, such as options and restricted stock awards, is not reflective of performance but depends upon the firm's growth. Two other interesting findings are that the prevalent use of stock-based compensation in the computer industry does not appear to be the result of computer firms being "cash starved. " In addition, stock-based compensation does not appear to lead to larger executive stock ownership, as is widely believed.
Mild cognitive impairment

Objective: We examined the incidence of mild cognitive impairment (MCI) and its potential vascular risk factors in a prospective population-based study. Methods: An age-stratified random population-based cohort (baseline n = 1,982), followed for up to 4 years, was annually assessed for cognitive and everyday functioning. Incidence rates were calculated for both cognitive (neuropsychological [NP]-MCI) and functional (Clinical Dementia Rating [CDR] = 0.5) definitions of MCI. Several measures of vascular, metabolic, and inflammatory risk were assessed at baseline. Risk factor analyses used interval censoring survival models, followed by joint modeling of both MCI and attrition due to mortality and illness. Results: Incidence rates for NP-MCI and CDR = 0.5 were 95 and 55 per 1,000 person-years. In individual joint models, risk factors for NP-MCI were diabetes and adiposity (waist: hip ratio), while APOE ε4 genotype and heart failure increased risk of attrition. Adiposity, stroke, heart failure, and diabetes were risk factors for nonamnestic MCI. For CDR = 0.5, risk factors were stroke and heart failure; heart failure and adiposity increased risk of attrition. In multivariable joint models combining all risk factors, adiposity increased risk of NP-MCI, while stroke and heart failure increased risk for CDR = 0.5. Current alcohol use appeared protective against all subtypes. Conclusion: Incidence of MCI increased with age regardless of definition and did not vary by sex or education. Several vascular risk factors elevated the risk of incident MCI, whether defined cognitively or functionally, but most were associated with nonamnestic MCI and CDR = 0.5. Controlling vascular risk may potentially reduce risk of MCI.
Characterization of Renal Allograft Rejection by Urinary Proteomic Analysis

ObjectiveTo develop a diagnostic method with no morbidity or mortality for the detection of acute renal transplant rejection. Summary Background DataRejection constitutes the major impediment to the success of transplantation. Currently available methods, including clinical presentation and biochemical organ function parameters, often fail to detect rejection until late stages of progression. Renal biopsies have associated morbidity and mortality and provide only a limited sample of the organ. MethodsThirty-four urine samples were collected from 32 renal transplant patients at various stages posttransplantation. Samples were collected from 17 transplant recipients with acute rejection and 15 patients with no rejection. Samples from patients less than 4 days posttransplant were omitted from data analysis due to the presence of excessive inflammatory response proteins. Rejection status was confirmed by kidney biopsy. Specimens were analyzed in triplicate using SELDI mass spectrometry. The obtained spectra were subjected to bioinformatic analysis using ProPeak as well as CART (Classification and Regression Tree) algorithms to identify rejection biomarker candidates. These candidates were identified by their molecular weight and ranked by their ability to distinguish between nonrejection and rejection based on receiver operating characteristic (ROC) analysis. The candidates with the highest area under the ROC curve (AUC) exhibited the best diagnostic performance. ResultsThe best candidate biomarkers demonstrated highly successful diagnostic performance: 6.5 kd (AUC = 0.839, P < .0001), 6.7 kd (AUC = 0.839, P < .0001), 6.6 kd (AUC = 0.807, P < .0001), 7.1 kd (AUC = 0.807, P < .0001), and 13.4 kd (AUC = 0.804, P < .0001). A separate analysis using the CART algorithm in the Ciphergen Biomarker Pattern Software correctly classified 91% of the 34 specimens in the training set, giving a sensitivity of 83% and specificity of 100% using two separate biomarker candidates at 10.0 kd and 3.4 kd. ConclusionsBiomarker candidates exist in urine that have the ability to distinguish between renal transplant patients with no rejection and those with acute rejection. These biomarker candidates are the basis for development of a noninvasive method of diagnosing acute rejection without the morbidity and mortality associated with needle biopsy. The combination of biomarkers into a panel for diagnosis leads to the possibility of enhanced diagnostic performance.
A toolchain for simplifying network simulation setup

Arguably, one of the most cumbersome tasks required to run a network simulation is the setup of a complete simulation scenario and its implementation in the target simulator. This process includes selecting a topology, provision it with all required parameters and, finally, configure traffic sources or generate traffic matrices. Many tools exist to address some of these tasks. However, most of them do not provide methods for configuring network and traffic parameters, while others only support a specific simulator. As a consequence, a user often needs to implement the desired features personally, which is both time-consuming and error-prone. To address these issues, we present the Fast Network Simulation Setup (FNSS) toolchain. It provides capabilities for parsing topologies from datasets or generating them synthetically, assign desired configuration parameters and generate traffic matrices or event schedules. It also provides APIs for a number of programming languages and network simulators to easily deploy the simulation scenario in the target simulator.
Direct Anatomical Localization of the Subthalamic Nucleus on CT with Comparison to Schaltenbrand-Wahren Atlas

Stimulation of the subthalamic nucleus (STN) has become an accepted treatment for motor symptoms of Parkinson’s disease. Generally, localization of the target is based on stereotactic atlas coordinates and magnetic resonance (MR) images. In this paper a method of direct anatomical localization of the STN on computed tomography (CT) images is described and compared with the Schaltenbrand-Wahren atlas. Serial CT scans were obtained at 1.5-mm interval and scan thickness of 3 mm, with the CT gantry and glabella-inion plane of the patient’s head vertical. The STN was identified as a dense structure medial to the inner semicircular border of the internal capsule in the subthalamic region. Its visibility was increased by changing the window and level settings on the CT workstation computer. The center of the STN in relationship to the intercommissural line, determined by this technique, was similar to those found on standard atlases.
Indri TREC Notebook 2006: Lessons Learned From Three Terabyte Tracks

This report describes the lessons learned using the Indri search system during the 2004-2006 TREC Terabyte Tracks. We provide an overview of Indri, and, for the ad hoc and named page nding tasks, discuss our general approach to the problem, what worked, what did not work, and what could possibly work in the future.
Image measurement of hand dimensions and model-based human hand posture estimation

We have a lot of products designed for use by hand, like a mobile phone, mouse, and camera, etc. These products can be used by many kinds of people whose hands come in various sizes. Designing a handheld product, therefore, it is required to consider the individual difference of user's hands. So there are the high expectations for simulating the interaction between user's hands in various sizes and the product in order to evaluate the product design without prototyping. To achieve it, the technology that generates various Digital Hands automatically from data of hand measurements and finds how a user grasps the product is needed. In this paper, we propose the method that measures 23 lengths and 9 widths included in all fingers automatically from a single image which is got by scanning palm side of a hand using any paper scanner. And we use these resultant measurements for estimating 9 thicknesses and 5 boundary lengths included in fingers or a palm that are perpendicular to the scanned surface. Finally, we try to deform the resultant Digital Hand model into a grasping posture.
Lower vs. higher fluid volumes in sepsis—protocol for a systematic review with meta‐analysis

Intravenous fluid administration with crystalloids is recommended in the initial management of sepsis. However, the quality of evidence supporting the recommendation on fluid volumes is low, and clinical equipoise exists. Potential benefits of restricting fluid volumes has been suggested, but the overall benefit or harm in patients with sepsis is unknown. Accordingly, we aim to assess patient‐important benefits and harms of lower vs. higher fluid volumes in resuscitation of adult patients with sepsis.
Stability trends and longitudinal correlations of negative and positive syndromes within a three‐year follow‐up of initially hospitalized schizophrenics

Our study investigates whether the distinction between positive and negative symptoms in schizophrenia – as discussed in the literature – can be confirmed by a factor analysis and whether such a distinction proves stability over time. In a further step, symptom factors are correlated to different external variables for the purpose of validation. Processed data cover 36 months obtained from a prospective 5‐year follow‐up study of 163 initially hospitalized schizophrenics. The results permit for dividing the symptoms into a total of five factors – two representing positive and negative symptoms and one representing the general neurotic syndrome. This factor structure proved to be stable over time. Correlations between symptom factors and external variables justify a trait‐interpretation of the negative factor anhedonia.
Adaptive state-feedback stabilization for high-order stochastic non-linear systems with uncertain control coefficients

This paper investigates the adaptive state-feedback stabilization problem for a class of high-order stochastic non-linear systems with unknown lower and supper bounds for uncertain control coefficients. Under some weaker and reasonable assumptions, a smooth adaptive state-feedback controller is designed, which guarantees that the closed-loop system has an almost surely unique solution on [0,∞, the equilibrium of interest is globally stable in probability and the states can be regulated to the origin almost surely. A simulation example is given to show the systematic design and effectiveness of the controller.
