This article originates from a panel with the above title, held at IEEE VTC Spring 2009, in which the authors took part. The enthusiastic response it received prompted us to discuss for a wider audience whether research at the physical layer (PHY) is still relevant to the field of wireless communications. Using cellular systems as the axis of our exposition, we exemplify areas where PHY research has indeed hit a performance wall and where any improvements are expected to be marginal. We then discuss whether the research directions taken in the past have always been the right choice and how lessons learned could influence future policy decisions. Several of the raised issues are subsequently discussed in greater details, e.g., the growing divergence between academia and industry. With this argumentation at hand, we identify areas that are either under-developed or likely to be of impact in coming years - hence corroborating the relevance and importance of PHY research. © 2006 IEEE.

Is the security scanner your favorite part of the airport experience? Does it bother you that you have to spend all that money on airline tickets in order to get scanned? If so, then this is the eBay listing for you: The Rapiscan Secure 1000 SP can be all yours for the low, low price of $7,995. According to eBay seller GovSurplus2012, the scanner normally costs $113,000 — but a "new government grant" created a need for new machines. "They have to justify the grant by buying new equipment, leaving good equipment for surplus," the seller writes. In fact, the TSA ended its contract with Rapiscan in 2013, when the company was unable to deliver more advanced and less invasive technology on a Congressionally-mandated timeline. The scanner uses a backscatter system, which was controversial because of the detailed images it creates of people's bodies. Congress ruled that scanner software must create less graphic images by June 2013, and the TSA and Rapiscan ended their contract when the deadline couldn't be met. The TSA now uses millimeter wave AIT scanners that do not create detailed body outlines, but instead show a generic body outline with markers when there is a potential threat. According to the listing, the Rapiscan Secure 1000 SP "bounces a very low dose of x-rays off of a person to generate an image. This image is then analyzed by an operator to identify concealed potential threats." And if you've got several Rapiscan fans on your holiday shopping list, you'll be glad to know there is more than one scanner available. "If you need more than one system, just let us know," the seller notes. Have something to add to this story? Share it in the comments.

Sundays have a way of being languid. You could be recovering from a hangover induced by the previous night’s binge. Or, you went to church, if such was your convention. Or you sat in your house and watched television – if there was power supply, whether from the national grid or from your generator. As the day wore on, you decided if, perhaps, there was some wisdom in paying someone a visit; alternatively, you accepted the fait accompli of a few folks, including disagreeable ones, looking in and setting you back by a few coins, thanks to the booze you would offer them. After the sun had withdrawn the sharper pricks of its burning fire, you could settle for watching on the silver screen as soccer stars justified their hefty paychecks and perquisites in the leagues of foreign countries. Whether the final scores gave you cheer or pain, both of which emotions should actually be pointless for the Nigerian, you watched the day gently slip away. You looked up to Monday morning, if you aren’t of the countless unemployed, that is. On Sunday, April 19, the evening caught me with not much to do. I didn’t see the point of venturing out. I would, whether or not I liked it, leave home to following day, to keep a 10am appointment. It was necessary to print out the 40 something pages of text I had written, so we chat over their import and chart the course of further work. I kept the printed pages on a side table and took to my bed, not to go to sleep at 5.30 pm, but to sate my rediscovered joy of reading Albert Camus, whose book of essays, The Myth of Sisyphus, I had handy. I hadn’t done an hour of reading when my phone rang. It was the same lady who had broken the news of General Emeka Ojukwu’s death to me in 2011. “Are you watching AIT?” She asked. I wasn’t watching anything, I replied. My TV wasn’t even on. “Switch it on and tune to AIT.” I told her I wasn’t prepared to do anything of the sort, unless she mentioned whatever awaited my confrontation. Thus, when I got to Comrade Uche Chukwumerije’s Maitama, Abuja home on April 20, it was not for us to look at the draft of two more chapters of his biography that I had written. Once I entered the house, Chika, the Olympic taekwondo champion, and one of Chukwumerije’s six sons, welcomed me with a handshake and this declaration: “Your friend is dead.” Although I had known of him since Biafra, my friendship with Chukwumerije started in 2000. That year, I had presented him with a copy of Ironside, my biography of General Aguiyi-Ironsi and, although it was rather presumptuous of me (not by any stretch of the imagination would anyone pretend that I and the comrade were transmitting from the same megahertz; he was up there and I was groping for the ropes with which to climb) I asked if he would please do a review of the book for its Enugu presentation. Chukwumerije gladly accepted the task. I believe it was Ironside that persuaded him years later to commission me to write his own biography. But the going wasn’t easy. He was busy at the Senate, and I held down the job of Chief of Staff to the Governor of Anambra State. Years later, when I had turned my back to the Awka political establishment, I returned to him with apologies on the slow pace of work on the biography. But he would not hear of it, insisting that nobody was to blame since we both had our hands full of other pressing responsibilities. Months later, I visited him one evening and watched with a certain alarm as he belaboured me for tardiness on the project. But, in a certain sense, Chukwumerije was a strange man. He didn’t dwell on infractions against his person. For instance, and as I found out in the course of my research, one of his half-brothers, an undergraduate, who was on vacation in his Lagos home, had decided that he had better use of Chukwumerije’s wristwatch. Chukwumerije found out, recovered the watch and instantly forgot the matter. Chukwumerije was easy to misunderstand because he was an epitome of bluntness; but innately, he was a most considerate and sensitive mind. He made a choice early in life to stand on the side of the downtrodden. He was a revolutionary who changed his mind at the last moment against embarking on a military career, deciding instead to fight his cause with the weapon of mass communication. He was an accomplished broadcaster and journalist. That was why, shortly after the civil war, he established Afriscope, an international monthly that mediated global developments from a purely African perspective. He had been a member of the Socialist Workers and Farmers Party (SWAFP) during the First Republic, and was one of the leaders of the left-leaning People’s Redemption Party (PRP) in the Second Republic. But two of the most important roles he played were (1) in Biafra, where he was directed the secessionist republic’s propaganda machinery, and (2) in the Interim Government of Ernest Shonekan in which he was Information Secretary. A good many of the views held on this man are tied to those epochs, but they tell far less than the entire story of his reason-induced and action-packed years. A few days ago, I got shown streams of an Internet conversation on Chukwumerije by Nigerian intellectuals mostly based in the United States. Professor Abiola Irele, the renowned literary critic, observed that, “Uche was a good friend and a great journalist. I wish him good repose.” He got stridently countered by Ebenezer Obadare, an associate professor of Sociology at the University of Kansas: “Thanks Professor Irele. But Senator Chukwumerije was more than that, and for the sake of posterity, it is important that even as we mourn, we continue to see clearly. “The departed senator was a malevolent force against the realization of democracy in Nigeria, and that too ought to be part of his memoriam. He trenchantly stymied the trajectory of a noble cause, and his deeds and misdeeds as the shameless factotum of the Shonekan and Abacha regimes brought grief to many families. “Part of doing justice to the memory of the dead has to be an honest accounting of what they did while alive. “May the senator rest in peece – and may the facts of his public service remain fresh in our memory.” Not surprisingly, Dr. Obi Nwakanma, the poet and Vanguard columnist, who teaches at the University of Central Florida, came to Chukwumerije’s defence: “Ebenezer. Uche Chukwumerije was a great Nigerian patriot who defended the interests of Nigeria as he saw it against imperialism by radical means. His work as a nationalist politician, from his days at the University College Ibadan, to his association with Otegbeye’s and Nzimiro’s Socialist Workers Party, and as Secretary-General of the PRP under the leadership of Mallam Aminu Kano in the Second Republic, and his service, his last hurrah as a senator of the republic who used his position in the Senate Education Committee to work for greater funding, particularly for Nigeria’s public universities, puts him beyond the pale of your characterization of him. It is often said that those who merely play drums for the Ijele on the side do not know the real toll it takes on the Ijele to carry the great mask. “Uche Chukwumerije did not oppose the June 12 mandate, he opposed the violation of Nigeria’s sovereignty by those who find easy comfort in urging the external invasion of Nigeria. He is a greater patriot than those who will, in the end live more in infamy than to question the true patriots who have put their feet on the ground for Nigeria, and have the marks to show for it. May Chukwumerije find rest. He is in the end, to be counted among the immortals of Nigeria.” In my view, the antipodal positions of Obadare and Nwakanma represent the tension that the biography I am working on must mediate. I may just add that Obadare’s invective is not outrageous. It is just too simply. But its simplicity is understandable, since it issues from this Age of Brevity where the social media not only allows but also actively promotes a brand of laziness that discourages the detailed exploration of antinomies. Really, it makes uncomplimentary remarks about the intellection of a people who experienced the profundity of the Nigerian civil war but have never really made any honest attempts at studying and fully appreciating its particularities and ramifications. That was why the publication of Chinua Achebe’s There Was A Country elicited from quarters thought to be academic more heat than light. That is also why, in recent weeks, all sorts of voices, including those of traditional rulers and medical doctors, have been in ascent, advocating yet another anti-Igbo pogrom. If Nigerian leaders are to be believed, the civil war was fought to keep Nigeria one. But what has continued to happen since the cessation of hostilities in January 1970, is the systematic consignment of the Igbo to a level worse than that of fourth-class citizens. In the 1979 general elections, there were five presidential candidates, one of whom was Dr. Nnamdi Azikiwe, an Igbo. And there were five vice-presidential candidates, four of whom were Igbo. In less than four decades, the condition of Ndigbo have, in a Nigeria ostensibly kept “one”, degenerated to a lack of right to live or school or work or trade in Lagos. They can’t even aspire to produce a Minister of the Federal Capital Territory of Abuja. They must spend the rest of their lives looking behind their backs, less they are caught unawares and massacred again in a fresh wave of ethnic cleansing. Comrade Uche Chukwumerije belonged to the fearless cadre of those loudly protesting that the current political status quo is a recipe for keeping Nigeria, not one, but two or many more. It is on this adamantine insistence on the imperative of justice and equity that his larger-than-life patriotic heroism is indexed.

An Ikeja High Court in Lagos on Wednesday adjourned a N150 billion libel suit filed by former Lagos State Governor, Asiwaju Bola Tinubu, against the African Independent Communication (AIT) till June 30. Justice Iyabo Akinkugbe adjourned the suit to enable Tinubu’s counsel respond to the counter-claim filed by AIT. Recall that Tinubu had instituted the suit against Daar Communications Plc, owners of AIT, for airing a documentary entitled, “Lion of Bourdilion”. In the suit, he alleged that the documentary, which started airing on March 1, was libelous and aimed at tarnishing his image. At the resumption of proceedings on Wednesday, AIT’s counsel, Mr Jeffery Kadiri, informed the court that the defendant had filed a counter-claim which had been served on the claimant. Responding, Tinubu’s counsel, Mr Ayodele Adedipe, said that the process was served on the claimant only two days ago, adding that he needed time to respond. Adedipe, therefore, asked the court for an adjournment and the judge acceded to his request. In the counter-claim, AIT listed its Chairman emeritus, Chief Raymond Dokpesi and seven others as witnesses to testify against Tinubu. Others listed to testify are : Namure Edoimioya, Chief Medan Tenke, Ajibola Adewusi, Olumide Idowu, Chief Stanley Odidi, Nwabueze and Dr Stanley Bassey. The broadcast outfit also denied each and every allegation of facts as contained in the claimant’s amended statement of claim. Dokpesi, in his statement on oath, averred that Tinubu’s claim was founded on none existing ground, because the said documentary was not entitled “The Lion of Bourdilon,” but “Unmasking the Real Tinubu”. He also averred that the documentary, in his honest opinion, was not false and was not aired out of malice to the person of the claimant. Dokpesi said that AIT, as a member of the fourth estate of the realm, was empowered by Section 22 of the Constitution to at all times, hold those in government accountable and responsible to the people of Nigeria. He further averred that the contents of the documentary were facts which had been in the public domain for over two decades. According to him, these are published independently, prior to the broadcast and have remained unchallenged till date.

REHOVOT, Israel and NEW YORK, May 1, 2015 /PRNewswire/ -- Advanced Inhalation Therapies Ltd (AIT), a leading anti-microbial therapeutic company, announced that the European Commission, acting on the recommendation from the Committee for Orphan Medicinal Products of the European Medicines Agency, granted orphan medicinal product designation to AIT-CF, the Company's proprietary high dose formulation of nitric oxide (NO), for the treatment of cystic fibrosis. The Orphan Designation is held by AIT's European agent, Biological Consulting Europe Ltd, which is located in the United Kingdom. AIT has completed a Phase IIa trial in adult CF patients. In February 2015, the Company disclosed that the U.S. Food and Drug Administration (FDA) also granted Orphan Drug Designation to AIT-CF for adjunctive treatment of cystic fibrosis (CF). Dr. David Greenberg, Chief Medical Officer of Advanced Inhalation Therapies, commented, "AIT-CF potentially affords a significant benefit to CF patients. As a naturally occurring chemical in the body, NO, when inhaled at high concentrations, kills bacteria and fungi in the lungs of CF patients and has shown broad anti-infective activity. The European Orphan Drug Designation for AIT-CF affords additional benefits as we continue to advance its clinical development." The European Commission's Orphan Designation is a status assigned to a medicine intended for use against a rare condition (prevalence of the condition in the European Union (EU) must not be more than 5 in 10,000). At the time of the designation, cystic fibrosis affected approximately 0.8 in 10,000 people in the EU or the equivalent of around 41,000 people based on current estimates. The EMA Orphan Medicinal Product Designation allows a pharmaceutical company to benefit from incentives offered by the EU to develop a medicine for the treatment, prevention or diagnosis of a disease that is life-threatening or a chronically debilitating rare disease. In addition to a 10-year period of marketing exclusivity in the EU after product approval, Orphan Medicinal Product Designation provides incentives for companies seeking protocol assistance from the EMA during the product development phase, and gives direct access to centralized marketing authorization route. Cystic Fibrosis (CF) is a lifelong, hereditary disease that causes mucus to form in the lungs and other organs. In 90% of CF cases, this mucus blocks the airways in the lungs, making it hard to breathe and leading to serious lung infections. For hospitalized CF patients, current treatments are supportive through the administration of oxygen through inhalation with bronchodilators, and include broad spectrum antibiotics and sometimes systemic steroids. Because these treatments do not eliminate all microbes, patients often suffer recurrent infections causing lung damage and ultimately in many cases respiratory failure. AIT is a biopharmaceutical company developing novel anti-viral therapeutics based on Nitric Oxide. The Company is applying its therapeutic expertise in NO to address significant medical needs, many of which cannot effectively be addressed with current standards of care, including small molecules and antibodies. AIT is building a pipeline of Nitric Oxide therapeutics as it has completed a Phase II trial for the treatment of respiratory syncytial virus (RSV) infection and a Phase II trial for the treatment of cystic fibrosis. The Company's leadership position in fundamental patents, technology, and know-how relating to NO has enabled it to develop a unique NO drug formulation for the treatment of RSV infection and Cystic Fibrosis. AIT's integrated proprietary system continuously monitors safety and efficacy parameters in patients. The Company, founded in 2011, maintains global headquarters in Rehovot, Israel and has an additional operating unit in New York, NY. For more information, visit http://www.AIT-Pharm.com .
