Handling unknown interference in cellular networks with interference coordination

We consider the downlink of a cellular network with cooperating multiple antenna base stations. On the one hand, each base stations tries to serve its associated mobile devices optimally, on the other hand, they try to minimize the interference they cause. Both goals could be achieved, if the interference channels would be zero. An adaptive beamforming based interference mitigation can only be performed for measured interference channels. To find an unachievable, but relatively tight upper bound we set the measured interference channels to zero. For such a limited cooperation, we show that the rates can be improved by predicting the interference over the unknown channels.
Internet Channel Entry: A Strategic Analysis of Mixed Channel Structures

By analyzing various alternative mixed channel structures composed of a monopoly manufacturer and online and offline outlets, we investigate how the specific channel structure and varying market conditions moderate the impact of Internet channel entry on the channel members and consumers. As an extension of Balasubramanian's model [Balasubramanian, S. 1998. Mail versus mall: A strategic analysis of competition between direct marketers and conventional retailers. Marketing Sci.173 181--195], our game-theoretic model captures the fundamental difference between two different channel types and consumer heterogeneity in preference for the Internet channel use. The equilibrium solutions indicate that Internet channel entry does not always lead to lower retail prices and enhanced consumer welfare. We also find that an independent retailer might become worse off after adding its own Internet outlet under certain market conditions. We find that the impact of the Internet channel introduction substantially varies across channel structures and market environments. We explain these varied results by proposing a framework of five key strategic forces that shape the overall impact of the Internet channel introduction.
Improving the Accuracy of Automatic Tennis Video Annotation by High Level Grammar

Automatic interpretation of videos in general and sports videos in particular relies heavily on the use of contextual information. The contextual information is encapsulated in form of grammars capturing the permissible relationships between the static and dynamic objects of the video content. The grammar is invariably multilevel, characterising the spatiotemporal relationships of pixels at the lowest level of analysis, and governing the interaction of objects and the evolution of concepts at the highest level of abstraction. An automatic video analysis system has been developed that applies multilevel contextual reasoning to understand and annotate tennis video. The system that exploits grammatical rules up to the point level achieves an impressive accuracy of 87.5%. We demonstrate that by adding an extra level in the contextual hierarchy which imposes constraints on the evolution of tennis video at the game level, further performance improvements can be gained.
On Geometric Modeling of the Human Intracranial Venous System

We describe a process aiming to construct a 3-D geometric model of the human normal intracranial venous system from MRA data. An analysis of geometric properties of the intracranial veins and sinuses results in proposing three models: circular, elliptic, and free-shape. We formulate a rule based on which a suitable geometric venous model can be selected. The cross-sectional shape of different parts of dural venous sinuses is found to be better approximated by ellipses and free shapes, while for veins the circular and elliptic models are comparable. An analysis of using splines for radii smoothing is also provided. The approach is useful for building venous models in education and clinical applications.
Extrusion Cooking Technology: An Advance Skill for Manufacturing of Extrudate Food Products

The snack industry is one of the fastest growing food sectors and is an important con- tributor within the global convenience food market. Nowadays snacks and convenience foods are also consumed regularly in India. Properly designed convenience foods can make an important contribution to nutrition in Indian societies where social changes are altering traditional patterns of food preparation. Extrusion cooking as a popular means of preparing snack foods based on cereals and plant protein foodstuff has elicited con siderable interest and attention over the past 30 years. Several studies on the extrusion of cereals and pulses, using various proportions, have been conducted because blends of cereals and pulses produce protein enriched products. Based on dough’s functional properties like WAI, WSI, ER and BD, the extruded products can be classified into differ ent group as per particular application. Therefore, this chapter is dealt with the effect of extrusion processing on product parameters, and nutritional and anti-nutritional proper ties of extruded product.
New Floating Gate Memory with Excellent Retention Characteristics

In current flash memory, there is an inevitable tradeoff between the operation voltage and the retention time due to the incorporation of very thin tunneling layer in the device structure. In this work, a new type of robust floating gate nonvolatile memory based on 2D materials is introduced to reduce the operation voltage and promote the data retention time. By taking the advantage of a dual‐gate structure, as‐fabricated devices exhibit excellent performance with low operation voltage (as low as 5 V even the tunneling layer t BN ≥ 10 nm), long retention time (on/off ratio with negligible degeneration over 105 s), and ultralow off‐leakage current (10−13 A, which is very attractive for ultralow‐power applications). Charges trapped in the top gate originated from the capacitive coupling between the back and top gates are found to be responsible for the nonvolatile behavior. The new charge trapping mechanism, which is distinguished from that in the conventional single‐gate memory devices, enables charge tunneling through a thicker tunneling layer at a low operation voltage. The achieved MoS2 nonvolatile memory with outstanding performances has great potentials for future information storage.

RGD-Binding Integrins in Head and Neck Cancers

Alterations in integrin expression and function promote tumour growth, invasion, metastasis and neoangiogenesis. Head and neck cancers are highly vascular tumours with a tendency to metastasise. They express a wide range of integrin receptors. Expression of the αv and β1 subunits has been explored relatively extensively and linked to tumour progression and metastasis. Individual receptors αvβ3 and αvβ5 have proved popular targets for diagnostic and therapeutic agents but lesser studied receptors, such as αvβ6, αvβ8, and β1 subfamily members, also show promise. This review presents the current knowledge of integrin expression and function in squamous cell carcinoma of the head and neck (HNSCC), with a particular focus on the arginine-glycine-aspartate (RGD)-binding integrins, in order to highlight the potential of integrins as targets for personalised tumour-specific identification and therapy.
Effect of Pathology on Union of First Metatarsophalangeal Joint Arthrodesis

Background: Arthrodesis is an established treatment for symptomatic degeneration of the first metatarsophalangeal (MP) joint. The published case series have often been small with different surgeons using a variety of joint preparation and fixation methods. The nonunion frequency comparing the different pathologies has not been described. We describe the senior author’s results comparing the union of an MP arthrodesis in hallux valgus, hallux rigidus, inflammatory arthropathy, and salvage surgery with identical joint preparation and fixation methods. Methods: The logbook of the senior author was used to identify the first MP joint arthrodeses from 2003 to 2011. The radiographic data were reviewed on the Picture Archiving and Communication system to assess the severity of deformity, radiographic union, type of fixation, and need for revision surgery. If there was no definite radiographic union of the last radiograph, the medical notes were reviewed. In all, 134 MP joint arthrodeses were performed in 78 females and 38 males, with a mean age of 65 ± 12 years (range, 20-94). Fixation was achieved by crossed screws (124) and dorsal plate (10). The primary diagnoses were hallux valgus in 49 joints (36.6%), hallux rigidus in 46 joints (34%), inflammatory arthropathy in 34 joints (25.4%), and salvage surgery in 5 joints (3.7%). Results: The overall radiographic union rate was 91.8% (123/134). There were significantly more nonunions in the hallux valgus group (14.3% vs 0%, OR 16, P = .05). Conclusion: Biplanar cuts and crossed screw fixation gave similar union frequencies to published case series. Hallux valgus was associated with higher nonunion frequencies in this single surgeon series. It may be that the hallux valgus group needs a stronger construct to achieve comparable union frequencies to the hallux rigidus group. Level of Evidence: Level III, retrospective comparative study.
Early human IgH gene assembly in Epstein-Barr virus-transformed fetal B cell lines. Preferential utilization of the most JH-proximal D segment (DQ52) and two unusual VH-related rearrangements

We have analyzed the phenotypic characteristics and IgH gene rearrangements in a panel of EBV-transformed B lineage cell lines from human fetal liver and bone marrow. Some lines contained only populations of immature, Ig- Be cells, while others contained mixed populations of mature and immature B cells. The majority of identifiable IgH rearrangements involved joining of the most JH- proximal D segment, DQ52, to various JH segments, implying that DQ52 is a preferred target for initial DJH rearrangements. Three other rearrangements involving VH-related sequences were also characterized. Two involved VHDJH joining using VH3 genes, although one of these had a very unusual DJH structure. The third consisted of inverted 3' signal sequences and flanking regions of a VH4 gene appended to a JH. The mechanisms by which the later rearrangement could have occurred and its potential physiological significance are discussed.

Presence of aerobic micro‐organisms and their influence on basic semen parameters in infertile men

Urogenital tract infections in males are one of the significant etiological factors in infertility. In this prospective study, 72 patients with abnormal semen parameters or any other symptoms of urogenital tract infection were examined. Semen analysis according to the WHO 2010 manual was performed together with microbial assessment: aerobic bacteria culture, Chlamydia antigen test, Candida culture, Ureaplasma and Mycoplasma‐specific culture. In total, 69.4% of semen samples were positive for at least one micro‐organism. Ureaplasma sp. was the most common micro‐organism found in 33% of semen samples of infertile patients with suspected male genital tract infection. The 2nd most common micro‐organisms were Enterococcus faecalis (12.5%) and Escherichia coli (12.5%), followed by Staphylococcus aureus (7%), Chlamydia trachomatis (7%) and Candida sp. (5.6%). Generally, bacteria were sensitive to at least one of the antibiotics tested. No statistically significant relationship was observed between the presence of aerobic micro‐organisms in semen and basic semen parameters: volume, pH, concentration, total count, motility, vitality and morphology.
Trends in the Use of Volunteers in US Hospices

Purpose: Using a longitudinal sample of freestanding Medicare-certified hospices in the 50 US states and the District of Columbia, this study sought to explore the factors associated with volunteer demand and describe how volunteer use has changed from 2000 to 2010. Results: A temporal decline in the extent of use of volunteers in freestanding hospices was observed over the study period. Findings indicated that both organizational and environmental factors influence the use of volunteers in US freestanding hospices. Conclusion: Given the importance of volunteers, both in the preservation of hospices’ philanthropic traditions and in reducing health care expenditure at the end of life, research is needed to further evaluate the factors associated with this decline. Emphasis should be placed on improving the retention of the existing hospice volunteer workforce.
The dynamics of a PWM boost converter with resistive input

This paper investigates the large- and small-signal response issues and, in particular, the inner loop gain and outer loop response of an indirect control method for active power-factor correction. The control scheme is based on sensing the average inductor current and generating a D/sub OFF/ (the complement of the switch duty cycle) which is proportional to the current. The method is demonstrated by considering the performance of a boost-type active power-factor corrector (APFC) that does not need to sense the input voltage. Theoretical and experimental results confirm the validity of the approach and demonstrate that the proposed method can be useful in the design of robust APFC with low total harmonic distortion. The indirect control method investigated in this paper is also compared to the classical direct APFC control method, pointing to the differences between the two.
Hough technique for bar charts detection and recognition in document images

Charts are common graphic representation for scientific data in technical and business papers. We present a robust system for detecting and recognizing bar charts. The system includes three stages, preprocessing, detection and recognition. The kernel algorithm in detection is newly developed modified probabilistic Hough transform algorithm for parallel lines clusters detection. The main algorithms in recognition are bar pattern reconstruction and text primitives grouping in the Hough space which are also original. The experiments show the system can also recognize slant bar charts, or even hand-drawn charts.
The Semantics of Motion

In this paper we present a semantic study of motion complexes (ie. of a motion verb followed by a spatial preposition). We focus on the spatial and the temporal intrinsic semantic properties of the motion verbs, on the one hand, and of the spatial prepositions, on the other hand. Then we address the problem of combining these basic semantics in order to formally and automatically derive the spatiotemporal semantics of a motion complex from the spatiotemporal properties of its components.
Efficient morphological algorithms for video structuring and indexing

In this paper we propose automatic tools useful for the segmentation and indexing of video documents. These tools provide a rst structure of a video document, which is a sound starting point allowing further sophisticated and dedicated algorithms to be run on its parts. Apart from being automatic, these tools are very simple, fast and e cient, due to the use of morphological lters. Two di erent detection algorithms of geometric (cuts, wipes) or chromatic (fades, dissolves) transitions are described, followed by a tool to select representative keyframes in a shot. Two other tools for inner shot change detection and detection of related shots are also presented, the latter being used in an application of newscaster detection.
Rodent Models for Human Polycystic Ovary Syndrome1

ABSTRACT Polycystic ovary syndrome (PCOS) is the most frequent female endocrine disorder, affecting 5%–10% of women, causing infertility due to dysfunctional follicular maturation and ovulation, distinctive multicystic ovaries and hyperandrogenism, together with metabolic abnormalities including obesity, hyperinsulinism, an increased risk of type 2 diabetes, and cardiovascular disease. The etiology of PCOS is unclear, and decisive clinical studies are limited by ethical and logistic constraints. Consequently treatment is palliative rather than curative and focuses on symptomatic approaches. Hence, a suitable animal model could provide a valuable means with which to study the pathogenesis of the characteristic reproductive and metabolic abnormalities and thereby identify novel and more effective treatments. So far there is no consensus on the best experimental animal model, which should ideally reproduce the key features associated with human PCOS. The prenatally androgenized rhesus monkey displays many characteristics of the human condition, including hyperandrogenism, anovulation, polycystic ovaries, increased adiposity, and insulin insensitivity. However, the high cost of nonhuman primate studies limits the practical utility of these large-animal models. Rodent models, on the other hand, are inexpensive, provide well-characterized and stable genetic backgrounds readily accessible for targeted genetic manipulation, and shorter reproductive life spans and generation times. Recent rodent models display both reproductive and metabolic disturbances associated with human PCOS. This review aimed to evaluate the rodent models reported to identify the advantages and disadvantages of the distinct rodent models used to investigate this complex endocrine disorder.
Meritocratic Fairness for Cross-Population Selection

We consider the problem of selecting a pool of individuals from several populations with incom-parable skills (e.g. soccer players, mathematicians, and singers) in a fair manner. The quality of an individual is deﬁned to be their relative rank (by cumulative distribution value) within their own population, which permits cross-population comparisons. We study algorithms which attempt to select the highest quality subset despite the fact that true CDF values are not known, and can only be estimated from the ﬁnite pool of candidates. Speciﬁcally, we quantify the regret in quality imposed by “meritocratic” notions of fairness, which require that individuals are selected with probability that is monotonically increasing in their true quality. We give algorithms with provable fairness and regret guarantees, as well as lower bounds, and provide empirical re-sults which suggest that our algorithms perform better than the theory suggests.
Premorbid Use of Clopidogrel Portends Worse Outcomes in Patients Treated Surgically for Intracranial Hemorrhage

Background: Widespread use of antiplatelet and anticoagulation medications (APACs) can be a difficult challenge in the presence of a neurosurgical emergency. Premorbid use of APACs, particularly clopidogrel, has been shown to affect outcomes in patients with stroke and traumatic brain injury. Objective: We hypothesized that pre-morbid clopidogrel use in patients with intracranial hemorrhage necessitating surgical intervention would lead to a greater risk of death and need for re-operation than those taking other APACs. Methods: Retrospective single institution review was conducted from January, 2010 through November, 2012 for intracranial hemorrhages necessitating surgical evacuation. Acute, subacute and chronic subdural, epidural and intraparenchymal hemorrhages were included. Results: 185 of 410 patients that required surgery for intracranial hemorrhage were on APACs. Overall mortality rate was 33%, with a 37% mortality rate in the APAC group. Overall reoperation rate was 7.5%, and 13% in the APAC group. Chi-square testing demonstrated significance between mortality and clopidogrel use (p = 0.0038), but not in APAC, warfarin or aspirin groups. There was statistical significance between the need for reoperation and APAC use (p = 0.002), aspirin use (p = 0.0097), and clopidogrel use (p = 0.0152), but not warfarin. Multivariate regression demonstrated only clopidogrel use is associated with higher mortality (p = 0.05) and need for reoperation (p = 0.0206). Conclusion: APAC use in the setting of intracranial hemorrhage necessitating surgical evacuation have higher intraoperative blood loss, need for transfusion and risk for adverse cardiac events. Premorbid clopidogrel use is associated with an increased risk in mortality and need for reoperation.
View Reconstruction by Linear Combination of Sample Views

Ullman and Basri [1] have shown theoretically, that a three-dimensional object can be represented by a linear combination of two-dimensional images of the object. But they have applied their calculations to artificially created images only, like line drawings of cars. The application to images of real objects turns out to be difficult, because a crucial point of their algorithm is the knowlegde of correspondences in the sample views. In this article we describe a biologically inspired system which automatically provides correspondences between views of a three-dimensional object. This enables us to apply Ullman and Basri’s linear combination approach to images of arbitrary, real objects. We give detailed formula of our linear combinations and examples for reconstructed object views.
Comparing the effectiveness of cache-resident tests against cycleaccurate deterministic functional patterns

This paper provides an overview of a flow to generate and apply cache-resident self-test (CReST) patterns on a CPU as an alternative to deterministic functional patterns. This paper also compares CReST patterns against deterministic functional patterns, including the results of a case study of applying both CReST and deterministic functional patterns on commercially available AMD x86 processors in high-volume production. The experiment indicates that CReST patterns are an effective substitute for functional patterns.
